    Urban soil is an important component of urban ecosystems. This study focuses on heavy metal contamination in soils of Wien (Austria) and results are compared to those for a few large European cities. We analysed the elemental contents of 96 samples of topsoil from urban, suburban and rural areas in Wien along a dynamic (floodplain forest) and a stable (oak-hornbeam forest) urbanization gradient. The following elements were quantified using ICP-OES technique: Al, As, Ba, Ca, Cd, Co, Cr, Cu, Fe, K, Mg, Mn, Pb, P, S and Zn. For heavy metals PI (pollution index) values were used to assess the level of pollution. The PI values indicated high level of pollution by Pb in the suburban and rural area of stable gradient and in the urban area of dynamic gradient; moderate level of pollution was indicated for Cd in the urban area of stable gradient. The level of pollution was moderate for Co in the suburban and rural area of the stable gradient, and for Cu in suburban area of stable gradient, and urban area of dynamic gradient. The pollution level of Zn was moderate in all areas. Urban soils, especially in urban parks and green areas may have a direct influence on human health. Thus, the elemental analysis of soil samples is one of the best ways to study the effects of urbanization. Our results indicated that the heavy metal contamination was higher in Wien than in a few large European cities.

    1983-08-01

    This discussion of Austria focuses on the following: geography, people, history, government, political conditions, economy, foreign relations, and relations between the US and Austria. As of July 1982, the population of Austria totaled 7.6 million with an annual growth rate of 0.1%. The infant mortality rate is 16/1000, and life expectancy is 73 years. Austria is primarily mountainous, and the climate is moderate. 99% of Austria's population are native German speakers. The only 2 significant minority groups are about 20,000 Slovenes in Carinthia and about 25,000 Croatians in Burgenland. The Austro-Hungarian Empire played a decisive role in central European history, partly because of its strategic position astride the southeast approaches to western Europe and the north-south routes between Germany and Italy. The president of Austria is directly elected to a 6-year term and may not serve more than 2 successive terms. As chief of state, the president's functions are largely representational. The chancellor (head of government) is either the leader of the party that wins the majority of seats in parliamentary elections and therefore can form a government or a coalition, or the leader of the party having the support of the president in the formation of a minority government. The chancellor selects the cabinet and, with its assistance, weilds actual power and is responsible to the Federal Assembly. The Federal Assembly (parliament) is composed of 2 houses--the National Council, or lower house, and the Federal Council, or upper house. Virtually all legislative authority is concentrated in the National Council. Since World War 2 Austria has enjoyed politcal stability. The 2 major parties that formed during the 1945-66 period have the support of about 90% of the electorate. Austria has a free enterprise economy in which the government plays an important role. More than half of the gross domestic product (GDP) comes from manufacturing and services. Austrian farms are small

    A new 4pi spin manipulator composed of two Wien filters oriented orthogonally and separated by two solenoids has been installed at the CEBAF/Jefferson Lab photoinjector. The new spin manipulator is used to precisely set the electron spin direction at an experiment in any direction (in or out of plane of the accelerator) and provides the means to reverse, or flip, the helicity of the electron beam on a daily basis. This reversal is being employed to suppress systematic false asymmetries that can jeopardize challenging parity violation experiments that strive to measure increasingly small physics asymmetries [*,**,***]. The spin manipulator is part of the ultra-high vacuum polarized electron source beam line and has been successfully operated with 100keV and 130keV electron beam at high current (>100 microAmps). A unique feature of the device is that spin-flipping requires only the polarity of one solenoid magnet be changed. Performance characteristics of the Two Wien Filter Spin Flipper will be summarized.

  6. Anomalous Wien Effects in Supercooled Ionic Liquids.

    2016-05-01

    We have measured conductivity spectra of several supercooled monocationic and dicationic ionic liquids in the nonlinear regime by applying ac electric fields with large amplitudes up to about 180  kV/cm. Thereby, higher harmonic ac currents up to the 7th order were detected. Our results point to the existence of anomalous Wien effects in supercooled ionic liquids. Most ionic liquids studied here exhibit a conductivity-viscosity relation, which is close to the predictions of the Nernst-Einstein and Stokes-Einstein equations, as observed for classical strong electrolytes like KCl. These "strong" ionic liquids show a much stronger nonlinearity of the conductivity than classical strong electrolytes. On the other hand, the conductivity-viscosity relation of the ionic liquid [P_{6,6,6,14}][Cl] points to ion association effects. This "weak" ionic liquid shows a strength of the nonlinear effect, which is comparable to classical weak electrolytes. However, the nonlinearity increases quadratically with the field. We suggest that a theory for explaining these anomalies will have to go beyond the level of Coulomb lattice gas models. PMID:27203333

  7. Eyesight and the solar Wien peak

    2003-03-01

    It is sometimes said that humans see best at yellow-green wavelengths because they have evolved under a Sun whose blackbody spectrum has a Wien peak in the green part of the spectrum. However, as a function of frequency, the solar blackbody spectrum peaks in the infrared. Why did human vision not evolve toward a peak sensitivity in this range, if the eye is an efficient quantum detector of photons? The puzzle is resolved if we assume that natural selection acted in such a way as to maximize the amount of energy that can be detected by the retina across a range of wavelengths (whose upper and lower limits are fixed by biological constraints). It is then found that our eyes are indeed perfectly adapted to life under a class G2 star. Extending this reasoning allows educated guesses to be made about the kind of eyesight that might have evolved in extrasolar planetary systems such as that of the red dwarf Gliese 876.

    The Drau Glacier was the largest Pleistocene glacier in the southeastern part of the Alps and significantly shaped the landscape in this region. The study area is located at the termination of the Drau Glacier in the southern part of Austria (Carinthia). The investigation aims to decipher glacial dynamics during the Late Pleistocene glacial advance, stabilisation and final recession of this glacier based on geological/geomorphological mapping, interpretation of airborne laser scan (ALS) topographic data and lithostratigraphic investigations of glacial and periglacial sediments. Special emphasis is laid on the reconstruction of the maximum extent of the glaciation (LGM). Based on previous mapping by Bobek (1959) and Ucik (1996-1998) more details have been gained for the paleogeographic reconstruction based on glacial and non-glacial erosion and accumulation features. These include traces of pre-Upper Pleistocene glaciation, drumlins, terminal moraines and kettle holes. Paleogeographic reconstruction was done with correlation of different outcrops based on lithostratigraphy and ALS topography. Sequences of gravel related to glacial advance covered by till, followed by periglacial sediments allowed detailed reconstruction of the glacial sequence in this area and the complex succession of various extents of the Drau Glacier.

  13. Analysis of Wien filter spectra from Hall thruster plumes.

    2015-07-01

    A method for analyzing the Wien filter spectra obtained from the plumes of Hall thrusters is derived and presented. The new method extends upon prior work by deriving the integration equations for the current and species fractions. Wien filter spectra from the plume of the NASA-300M Hall thruster are analyzed with the presented method and the results are used to examine key trends. The new integration method is found to produce results slightly different from the traditional area-under-the-curve method. The use of different velocity distribution forms when performing curve-fits to the peaks in the spectra is compared. Additional comparison is made with the scenario where the current fractions are assumed to be proportional to the heights of peaks. The comparison suggests that the calculated current fractions are not sensitive to the choice of form as long as both the height and width of the peaks are accounted for. Conversely, forms that only account for the height of the peaks produce inaccurate results. Also presented are the equations for estimating the uncertainty associated with applying curve fits and charge-exchange corrections. These uncertainty equations can be used to plan the geometry of the experimental setup. PMID:26233378

  14. Tornado climatology of Austria

    Holzer, A. M.

    After several decades of little work, a revised tornado climatology for Austria is presented. Tornadoes seldom form in the alpine areas, however, near the eastern flanks of the Alps, favourable conditions for tornado genesis are found. Whereas in the alpine regions less than 0.3 tornadoes per 10,000 km 2 a year touch down (averaged for provinces or major parts of a province), we can count 0.9 in the greater Graz area, 1.0 in the greater Linz area and 1.2 tornadoes per 10,000 km 2 a year in the greater Vienna area, suggesting the existence of so-called tornado alleys. As these regions are the most populated areas of Austria, there is a possible population bias in the dataset. The overall average for Austria is 0.3 tornadoes per 10,000 km 2 a year. The database consists of 89 tornadoes, one landspout and six waterspouts, with a total of 96 events. The seasonal peak is in July with a maximum probability of tornadoes in the late afternoon and early evening hours. Every fifth tornado occurs in the hour after 5 p.m. The maximum intensity determined for a tornado in Austria was T7 on the TORRO-Scale (F3 on the Fujita-Scale), the most common intensity is T2 on the TORRO-Scale (F1 on the Fujita-Scale).

  16. Ray-tracing analysis of the Wien velocity filter for protons

    NASA Astrophysics Data System (ADS)

    Kim, Jae Hong; Kim, Yu-Soek

    2015-02-01

    A Wien velocity filter employs a combination of crossed magnetic and electrostatic fields in order to select the desired velocity of ions. Several microscopes and spectrometers are used as filters to ensure the introduction of a pure ion fraction into the lens, deflecting unnecessary particles which have slightly different energies. The Wien filter is also considered to be a useful device to transport mono-energy protons from a source to an injection system. In its simplest form, the Wien filter has two flat parallel electrodes that are arranged between two flat magnet poles, creating homogeneous electric and magnetic fields which cross each other. However, this type of filter has no focusing effect in the direction of the magnetic field and has an unmatched field distribution, which causes deflections of protons at the entrance and the exit of the filter. At higher magnetic field strengs, for fast protons, the deflection of the trajectories becomes larger; thus, the transport efficiency is reduced. A low-aberration velocity filter is needed for high transport efficiency. Recently, a stigmatic focusing of the filter by using hyperbolic cylindrical magnet pole pieces, which produce an inhomogeneous magnetic field inside the ExB filter, has been suggested. In this research, three types of Wien filters were designed in order to investigate the geometry of the electrodes and the magnet poles, thus minimizing aberrations. Ray-tracing analyses were carried out to estimate the performance of the proposed Wien filters within a useful velocity selector.

    In 2007 Austria reported a total of 438 foodborne outbreaks affecting 1715 people, including 286 hospitalized patients and one death. Salmonella spp. and Campylobacter spp. accounted for 95% of all reported outbreaks. Forty-eight (11%) of the 438 Austrian outbreaks were acquired abroad. Of the 390 domestically acquired foodborne outbreaks, bacterial infection caused 376, viruses (norovirus and 1-time hepatitis A virus) caused 11, and intoxications (Staphylococcus aureus enterotoxins, alkaloid toxins) caused two. In one outbreak the causative agent was unknown. Salmonella spp. caused 264 (70%) of the bacterial outbreaks, Campylobacter spp. caused 104 (28%), enterohemorrhagic Escherichia coli (EHEC O145:H-, O157:H-, O157:H7, O182: H49, O91:H7, ONT:H4) caused six, Shigella flexneri and Shigella sonnei each caused two. The hospitalization rates were 22% for domestically acquired infections with Salmonella spp. and 14% for Campylobacter spp. Among outbreaks where the source was known, eggs were implicated in 49%, meat products (especially poultry) in 44% and fish in 2%. The ratio of household outbreaks to general outbreaks was 82.3% to 17.7%. In 54 of the 62 general domestic outbreaks the following locations of exposure were documented: commercial food suppliers (e.g. restaurants, cafeterias) 24 times, family celebrations, nursery schools, take-aways and barbecues 22 times, nursing homes and hospitals eight times. It is likely that the relatively high number of household outbreaks reflects an insufficient level of epidemiological investigation of outbreaks in Austria. More resources may be needed for identification of individual clusters that belong to larger foodborne outbreaks exceeding district or provincial borders. PMID:19280130

    2016-03-01

    The purpose of this article was to compile all existing data regarding the prevalence of obesity in Austria in all age groups, and to perform additional analyses. Prevalence of obesity in the adult Austrian population varies between 8.3 and 19.9% in men, and 9.0 and 19.8% in women with increasing trends over time. Prevalence of obesity in children and adolescents in Austria varies between 3.1 and 9.0% in boys and between 2.2 and 7.3% in girls. Factors associated with obesity include higher age, lower educational level, profession, migration background, living in eastern parts of Austria, lack of social support, and psycho-social pressure. In women, socio-economic parameters are stronger associated with obesity compared to men. Obesity is associated with hypertension, diabetes mellitus, osteoarthritis, and low back pain, and deteriorated quality of live, in both sexes, and in men additionally with a history of heart attack, and in women additionally with anxiety/depression.

    2012-04-01

    A new flood model for Austria quantifying fluvial flood losses based on probabilistic event set developed by Impact Forecasting (Aon Benfield's model development centre) was released in June 2011. It was successfully validated with two serious past flood events - August 2002 and August 2005. The model is based on 10 meters cell size digital terrain model with 1cm vertical step and uses daily mean flows from 548 gauge stations of series of average length ~ 60 years. The even set is based on monthly maxima flows correlation, generating 12 stochastic events per year and allows to calculate annual and occurrence exceedance probability loss estimates. The model contains flood extents for more than 24,000 km of modelled river network compatible with HORA project (HOchwasserRisikoflächen Austria) for design flows ranging from 2 to 10,000 years. Model is primarily constructed to work with postal level resolution insurance data reducing positional uncertainty by weighting over more than 2.5 millions address points from Austria Post's ACGeo database. Countrywide flood protections were provided by the Austrian Ministry of Environment. The model was successfully tested with property portfolios of 8 global and local insurance companies and was also successfully validated with August 2002 and August 2005 past events evaluating their return period on the probabilistic simulation basis.

    This paper presents simulations of a mass spectrometer composed of one or two Wien filters. The ion source used is MONO1000 ECRIS. This ion source can produce singly charged ions with high efficiency, especially for gaseous materials. After extraction, the ions are mass selected and can be injected either into a beam line towards an experiment area or in an N+ charge booster. Due to its compactness and simplicity the proposed spectrometer is well adapted for preparing and analyzing radioactive beams. The simulations are based on the SIMION 3D [www.simion.com/] software.

    1985-07-01

    A summary description of Austria's demographic situation, economic conditions, labor force characteristics, housing conditions, household characteristics, and marriage patterns is provided. Austria, the former center of the Hapsburg Empire, covers 32,375 square miles and is divided into 9 provinces, including Vienna, the federal capital. Austria's population increased from 6.9 million in 1950 to 7.6 million in 1980. Since 1980 it declined slightly and in 1985 it was estimated to be 7,487,000. Between 1961-81, the industrial, western region of the country grew more rapidly than the predominantly rural eastern section of the country. Vienna, the largest city in the country, experienced a decline in population size from 1.9 million to 1.5 million since 1923. Part of the decline was due to the annihilation of the city's Jewish population in 1938. Austria has a lower urban population (56%) than most other industrialized countries. This low rate reflects the availability of tourist related jobs in the rural areas. 98% of the population is Austrian, the official language is German, and most of the inhabitants are Roman Catholic. Due to the homogeneity of the population, the country has few religious and racial problems; however, a recent study indicated that about 1/2 of the population has anti-Semetic attitudes. Life expectancy is 69 years for men and 76 years for women. Austria's population is aging. Currently, 18% of the population is under 15 years of age, and 14% is 65 years of age or older. Births are expected to increase slightly until the end of the 1900s and then decline slightly. Austrians place a high value on children and family life. Between 1978-82 the marriage rate increased from 4.5/1000 to 4.8/1000, and the median age at marriage increased from 22.4-23.0 years for women and from 25.6-25.8 years for men. The number of divorces/year increased from 11,168-14.298 between 1976-82. Currently, there are 2,767,000 households, and the average household size is 2

    The conventional Wien filter is a device with orthogonal static magnetic and electric fields, often used for velocity separation of charged particles. Here we describe the electromagnetic design calculations for a novel waveguide RF Wien filter that will be employed to solely manipulate the spins of protons or deuterons at frequencies of about 0.1-2 MHz at the COoler SYnchrotron COSY at Jülich. The device will be used in a future experiment that aims at measuring the proton and deuteron electric dipole moments, which are expected to be very small. Their determination, however, would have a huge impact on our understanding of the universe.

    The gas cluster ion beam (GCIB) and liquid metal ion beam have been studied in the context of ion beam usage for analytical equipment in applications such as X-ray photoelectron spectroscopy and secondary ion mass spectroscopy (SIMS). In particular, small ion sources are used for the secondary ion generation and ion etching. To set the context to this study, the SIMS project has been launched to develop ion-gun based analytical equipment for the Korea Basic Science Institute. The objective of the first stage of the project is the generation of argon beams with a GCIB system [A. Kirkpatrick, Nucl. Instrum. Methods Phys. Res., Sect. B 206, 830-837 (2003)] that consists of a nozzle, skimmer, ionizer, acceleration tube, separation system, transport system, and target. The Wien filter directs the selected cluster beam to the target system by exploiting the velocity difference of the generated particles from GCIB. In this paper, we present the theoretical modeling and three-dimensional electromagnetic analysis of the Wien filter, which can separate Ar(+) 2500 clusters from Ar(+) 2400 to Ar(+) 2600 clusters with a 1-mm collimator.

    This guideline which is endorsed by the Austrian Society of Haemophilia, the Austrian Society of Paediatrics, and the Austrian Society of Haematology & Medical Oncology is intended to give a clear and practical guidance for diagnosing and treating haemophilia in Austria. In the treatment of haemophilia there are few controlled interventional trials, and recommendations usually have a rather low level of evidence.The main basis for this paper are the new international guidelines by the World Federation of Hemophilia, published in 2013. These were adapted according to the local situation and experience.Covered topics are diagnostics, control visits, pharmacological treatment options, prophylaxis and treatment in children and adults, possible problems arising in haemophilia carriers and special aspects like home therapy, options for venous catheters, management of various traumas, bleedings and interventions, including dental procedures, and last not least inhibitors and their treatment.

    Austria has a long and successful tradition in geriatric medicine, nursing and sociology. In contrast, research in experimental gerontology has only come into focus more recently. Gerontological research is performed in various laboratories and clinics of the Medical Schools of the Universities of Vienna, Graz and Innsbruck, respectively, as well as in the School of Veterinary Medicine in Vienna, the Institute for Applied Microbiology of the Vienna University for Agricultural Sciences, the Faculty of Natural Sciences of the University of Salzburg, and in extra-universitary institutions such as the Ludwig-Boltzmann-Institute for Aging Research in Vienna and the Institute for Biomedical Aging Research of the Austrian Academy of Sciences in Innsbruck. Therefore, the following brief reflections will be organized in a topographic fashion.

    According to current European and international recommendations (e.g. by IAEA, WHO and European Union), countries shall identify high radon areas. In Austria, this task was initiated already in the early 1990s, which yielded the first Austrian Radon Potential Map. This map is still in use, updated with recent indoor radon data in 2012. The map is based on radon gas measurements in randomly selected dwellings, normalised to a standard situation. To meet the current (legal) requirements, uncertainties in the existing Austrian radon map should be reduced. A new indoor radon survey with a different sampling strategy was started, and possible mapping methods are studied and tested. In this paper, the methodology for the existing map as well as the planned strategies to improve this map is discussed.

    Johann Palisa discovered the first asteroid (136) Austria in 1874 at the Austrian Naval Observatory in Pola, Istria. After discovering 27 more objects in Pola, Palisa was offered a position in Vienna where he had the new large refractor (at that time the largest telescope in the world) at his disposal. During his career he discovered a total of 121 asteroids, making him the most successful discoverer of minor planets using visual techniques. Joseph Rheden used the new technology of photography to continue the program. He concentrated on measurements of positions for the purpose of orbit determination. At the same time Theodor Oppolzer introduced a new method of orbit determination which was applied to the observations. International cooperations resulted among other projects in the production of the Wolf-Palisa charts, and, much later, in a remeasurement of the original plates and use of the data for the improvement of orbit determination. This successful field of research came to an end because of the deterioration of observing conditions in Vienna, financial problems due to the political and economic decline following World War I and the death of Palisa in 1925.

  12. ATAT@WIEN2k: An interface for cluster expansion based on the linearized augmented planewave method

    2010-05-01

    We have developed an interface between the all-electron density functional theory code WIEN2k, and the MIT Ab-initio Phase Stability (MAPS) code of the Alloy-Theoretic Automated Toolkit (ATAT). WIEN2k is an implementation of the full-potential linearized augmented planewave method which yields highly accurate total energies and optimized geometries for any given structure. The ATAT package consists of two parts. The first one is the MAPS code, which constructs a cluster expansion (CE) in conjunction with a first-principles code. These results form the basis for the second part, which computes the thermodynamic properties of the alloy. The main task of the CE is to calculate the many-body potentials or effective cluster interactions (ECIs) from the first-principles total energies of different structures or supercells using the structure-inversion technique. By linking MAPS seamlessly with WIEN2k we have created a tool to obtain the ECIs for any lattice type of an alloy. We have chosen fcc Al-Ti and bcc W-Re to evaluate our implementation. Our calculated ECIs exhibit all features of a converged CE and compare well with literature results.

  13. Economic burden of osteoporotic fractures in Austria

    PubMed Central

    2012-01-01

    Objective Osteoporotic fractures impose a huge economic burden on society. Though several cost of illness studies from other countries exist, no equivalent study has been conducted in Austria. Our study aims at assessing costs resulting from osteoporotic fractures in Austria in the year 2008 from a societal perspective. Methods We took both direct and indirect costs into consideration. Direct costs encompass medical costs such as expenses for pharmaceuticals, inpatient and outpatient medical care costs, as well as other medical services (e.g., occupational therapies). Non-medical direct costs include transportation costs and medical devices (e.g., wheel chairs or crutches). Indirect costs refer to costs of productivity losses due to absence of work. Moreover, we included costs for early retirement and opportunity costs of informal care provided by family members. For our analysis, we combined data of official statistics, expert estimates as well as unique patient surveys that are currently conducted in the course of an international osteoporotic fracture study in Austria. Results For the year 2008, the total annual financial burden incurred by osteoporotic fractures in Austria amounted to approx. €685.2 million, the largest fraction of which was due to the opportunity cost of family care (30.2%), followed by costs for hospitalization (26.6%). Conclusions The financial burden of osteoporotic fractures in Austria is substantial. Our findings may have implications for future economic analyses, and also support health care authorities in their decision making. PMID:22827971

    The main aim of this work is to study crustal granulite xenoliths from Beistein (Styrian Basin, Austria). Styrian-basin is situated at the westernmost part the Pannonian-basin-system. We collected 17 felsic granulite xenoliths, from basaltic pyroclastics near Beistein. We made petrography, geothermo-barometry and fluid inclusion studies to find out their evolution and fluid content and to make a comparison with other crustal xenoliths found in the Pannonian Basin. The petrography shows, that these xenoliths experienced 3 evolutional stages. At the beginning, a felsic magmatic body intruded into the middle crust. It contained feldspar, pyroxenes, quartz, biotite, opaque minerals, apatite and zircon. This intrusion experienced cooling. This cooling generated the stable mineral assemblage of the granulite facies (feldspar + orthopyroxene + quartz ± garnet) at p=5.5-6.7 kbar and T= 800-850oC and resulted in antiperthitic exsolution of feldspars. The third step was the uplift of the xenoliths in the basalt to the surface which generated temperature increase, and pressure decrease. Considering the petrology of the fluid inclusions (FI) in these xenoliths, there are primary and secondary FIs in the samples. This shows us, that there were minimum of two fluid events (fluid-rock interaction). The very first fluid event coeval with the emplacement and crystallization of the magmatic body in the deep crust, witnessed by primary inclusions in the relict magmatic minerals like apatite and zircon. There are other primary FIs also in the main rock-forming minerals, such as plagioclase, quartz and pyroxenes. The second fluid event happened still in the lower crust. This produced the secondary FI rows along healed fractures mostly in the felsic minerals. The microthermometry shows, that CO2 was the dominant fluid phase in the crust, but genetically the different FIs have different compositions. The melting temperatures (Tm) of primary FIs were between -58,0 and -65,6 °C, and that

    AlpArray Austria is a research project to study the geodynamics of the Eastern Alps and the subsurface of Austria with a large-scale mobile broadband seismological network. AlpArray Austria is part of the AlpArray project - a unique European transnational research initiative in which 64 research institutes from 17 countries join their expertise to advance our knowledge about the structure and evolution of the lithosphere beneath the entire Alpine area. AlpArray Austria is coordinated by the Department of Meteorology and Geophysics (IMGW) at the University of Vienna and funded by the Austrian Science Fund (FWF). During spring 2015 the deployment of 42 mobile broadband seismometers (and two permanent stations) will commence and by autumn 2015 Austria will be completely covered by a dense seismological network with an average station spacing of about 40 kilometers. The mobile network consisting of 27 Reftek 151 60s sensors (provided by IMGW) and 15 Trillium 120s instruments (provided by the Dublin Institute for Advanced Studies, DIAS, Ireland) will complement the permanent Austrian seismic network operated by the Austrian Zentralanstalt für Meteorologie und Geodynamik (ZAMG) that will also install the two permanent stations. AlpArray Austria will be continuously recording high-quality ground motion data for three years. Seismic data will be distributed through the European Integrated Data Archive (EIDA) and shared with the collaborating AlpArray institutes. AlpArray Austria will shed light on the detailed geological structure and geodynamical evolution of the Eastern Alps and the subsurface of Austria. Utilizing seismic analysis methods such as shear wave splitting, receiver functions and body wave dispersion the AlpArray Austria working group at IMGW will, together with the international partners, focus on seismic anisotropy in the upper mantle, the location of interfaces and tomography, to answer outstanding questions on slab geometry and subduction polarity under

  6. Influenza vaccination in Austria, 1982-2003.

    2007-01-01

    Since the past decade influenza vaccination is becoming an increasingly important aspect of public health programs. In the early 1990s independent investigators began to gather information on the comparative use of influenza vaccine in developed countries. The annual level of influenza vaccine distributed in each country was calculated as the number of doses distributed per 1000 total resident population. During the first period of research in 18 developed countries influenza vaccine was widely underused. From 1980 to 1992 the annual vaccination rates increased in most of the 18 countries. But Austria (Switzerland and Finland) showed little change (20 doses/1000 in 1982 and 23 doses in 1992). When in 1992-1995 four new countries were included, doses increased slightly in Austria, too, to about 52 doses/1000 in 1995, but the country still belonged to the low-use countries compared to Spain 160 doses/1000, although vaccination was recommended for all elderly people <65 years and persons with high-risk medical conditions. Self-payment was usual, and there was no reimbursement within the national or social health insurance schemes. From 1996 (77 doses/1000), to 2000 (118 doses/1000) and 2003 (127 doses/1000), vaccination increased slightly, but Austria remained one of the lowest three Western European countries reported, together with Sweden (127) and Norway (102). Possible reasons for the low usage in Austria may be the following: people mistake influenza for an influenza-like illness, a lack of effective social marketing, costs are not taken over by social or private insurance and discordance in the Austrian medical fraternity about the importance of vaccination. Especially in view of a possible new influenza pandemic, public awareness of the importance of vaccination must increase. PMID:17427004

  7. Biometeorology in austria: past, present and future

    NASA Astrophysics Data System (ADS)

    Dirmhirn, Inge

    1991-09-01

    Biometeorology in Austria has been shaped by concepts, personalities, and technology. In early times, the branches of biometeorology that are usual today were already evident: agricultural and forest meteorology, phenology, medical biometeorology and balneology, aerial biometeorology, urban housing and stabling meteorology all started to emerge several centuries ago. From the 1920 up to 1936, Wilhelm Schmidt at the Agricultural University of Austria laid the foundations of modern biometeorology. He was followed by Franz Sauberer, who headed a Department of Biometeorology at the National Weather Service and devoted his active life totally to biometeorology. Several years after his untimely death, the Department was dissolved. Not until 1981 was biometeorology taken up again at the Agricultural University, where the tradition of Schmidt and Sauberer now lives on in several courses within the area of applied biometeorology: Micro-and Topoclimatology, Agricultural and Forest Meteorology and Atmospheric Radiation. Biometeorology, being an experimental science, has also been influenced by new technological developments. The early period was exclusively observational. During the late nineteenth and early twentieth centuries mechanical and simple electric instruments were used with strip-chart recorders. These time consuming methods have now been replaced by electronic devices, including data loggers and portable computers along with many new electronic sensors, which provide additional insight into biometeorological problems. Since computers also make it possible to solve some of the complicated equations of biometeorology, the future of this science seems to be bright, not only in Austria but throughout the world.

    In Austria, a total of 606 food borne outbreaks, affecting 1,910 people altogether (including 368 hospitalized patients and 1 fatal outcome) were documented in 2005. Salmonella spp. and Campylobacter spp. accounted for 99% of all reported outbreaks. Fortysix (8%) of the 606 outbreaks were acquired abroad. Bacteria caused all but one of the 560 domestically acquired food borne outbreaks: 427 (76%) were due to Salmonella spp., 128 (23%) due to Campylobacter spp. and two outbreaks each due to enterohaemorrhagic Escherichia coli and Yersinia enterocolitica. Norovirus caused an outbreak affecting 22 persons. The respective hospitalization rate for domestically acquired Salmonella spp. and Campylobacter spp. infections was 20% and 16%. Of those outbreaks where information as to the source was provided, eggs were implicated in 57%, meat products (especially poultry) in 30% and milk or dairy products (especially raw milk) in 4%. The ratio between family outbreaks and general outbreaks was 89% to 11%. For general outbreaks the following locations of exposure were given: commercial food suppliers (incl. restaurants, cafeterias) 34 x, family celebrations 14 x, nursery schools 4 x, festivities (e.g. fairs) 3 x, nursing homes twice and once a mixed outbreak involving commercial food suppliers plus homes (Austria-wide S. Enteritidis PT19 outbreak). In our opinion, the relatively high number of family outbreaks merely reflects the still insufficient quality of epidemiological outbreak investigation in Austria, i.e. lack of consolidating individual clusters into larger food borne outbreaks which exceed district or provincial borders.

    It has been possible to measure glacier recession on the basis of Landsat data, in conjunction with comparisons of the magnitude of recession of a glacier margin with in situ measurements at fixed points along the same margin. Attention is presently given to the cases of Vatnajokull ice cap, in Iceland, and the Pasterze Glacier, in Austria, on the basis of satellite data from 1973-1987 and 1984-1990, respectively. Indications of a trend toward negative mass balance are noted. Nevertheless, while most of the world's small glaciers have been receding, some are advancing either due to local climate or the tidewater glacier cycle.

The seven foreigners stayed in four hotels located in a geographical diameter of less than 10 km. Two cases were diagnosed in The Netherlands and five in the UK. The first case occurred in 1992, while the remaining cases clustered between August 2000 and April 2004. None of these cases was reported officially as part of a hotel-associated cluster, thereby highlighting several weaknesses of the infectious disease control systems involved.

    It has been possible to measure glacier recession on the basis of Landsat data, in conjunction with comparisons of the magnitude of recession of a glacier margin with in situ measurements at fixed points along the same margin. Attention is presently given to the cases of Vatnajokull ice cap, in Iceland, and the Pasterze Glacier, in Austria, on the basis of satellite data from 1973-1987 and 1984-1990, respectively. Indications of a trend toward negative mass balance are noted. Nevertheless, while most of the world's small glaciers have been receding, some are advancing either due to local climate or the tidewater glacier cycle. 21 refs.

  19. Assessing the accuracy of the Second Military Survey for the Doren Landslide (Vorarlberg, Austria)

    Reconstruction of the early and long-term evolution of landslide areas is especially important for determining the proportion of anthropogenic influence on the evolution of the region affected by mass movements. The recent geologic and geomorphological setting of the prominent Doren landslide in Vorarlberg (Western Austria) has been studied extensively by various research groups and civil engineering companies. Civil aerial imaging of the area dates back to the 1950's. Modern monitoring techniques include aerial imaging as well as airborne and terrestrial laser scanning (LiDAR) providing us with almost yearly assessment of the changing geomorphology of the area. However, initiation of the landslide occurred most probably earlier than the application of these methods, since there is evidence that the landslide was already active in the 1930's. For studying the initial phase of landslide formation one possibility is to get back on information recorded on historic photographs or historic maps. In this case study we integrated topographic information from the map sheets of the Second Military Survey of the Habsburg Empire that was conducted in Vorarlberg during the years 1816-1821 (Kretschmer et al., 2004) into a comprehensive GIS. The region of interest around the Doren landslide was georeferenced using the method of Timár et al. (2006) refined by Molnár (2009) thus providing a geodetically correct positioning and the possibility of matching the topographic features from the historic map with features recognized in the LiDAR DTM. The landslide of Doren is clearly visible in the historic map. Additionally, prominent geomorphologic features such as morphological scarps, rills and gullies, mass movement lobes and the course of the Weißach rivulet can be matched. Not only the shape and character of these elements can be recognized and matched, but also the positional accuracy is adequate for geomorphological studies. Since the settlement structure is very stable in the

    Concentrations of 26 elements (B, Na, Mg, P, S, K, Ca, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, As, Se, Rb, Sr, Mo, Cd, Sb, Ba, Hg, Pb, U) in wild game meat from Austria were analysed using an inductively coupled plasma mass spectrometer. All investigated animals were culled during the hunting season 2012/2013, including 10 chamois (Rupicapra rupicapra), 9 hare (Lepus europaeus), 10 pheasant (Phasianus colchicus), 10 red deer (Cervus elaphus), 12 roe deer (Capreolus capreolus) and 10 wild boar (Sus scrofa). In 19 out of 61 meat samples lead concentrations were higher than 0.1 mg/kg, the maximum limit in meat as set by the European Commission (Regulation EC No 1881/2006), which is most likely caused by ammunition residues. Especially, pellet shot animals and chamois show a high risk for lead contamination. Despite ammunition residues all investigated muscle samples show no further health risk with respect to metal contamination. PMID:26886253

  1. Space Radar Image of Oetzal, Austria

    NASA Technical Reports Server (NTRS)

    1999-01-01

    This image is a false-color composite of Oetzal, Austria located in the Central Alps centered at 46.8 degrees north latitude, 10.70 degrees east longitude, at the border between Switzerland (top), Italy (left) and Austria (right and bottom). The area shown is 50 kilometers (30 miles) south of Innsbruck, Austria. This image was acquired by the Spaceborne Imaging Radar-C and X-Band Synthetic Aperture Radar (SIR-C/X-SAR) aboard the space shuttle Endeavour on its 14th orbit. Oetztal is a SIR-C/X-SAR hydrology supersite. Approximately one quarter of this image is covered by glaciers, the largest of which, Gepatschferner, is visible as a triangular yellow patch in the center of the scene. The summits of the main peaks reach elevations between 3,500 and 3,768 meters (11,500 and 12,362 feet) above sea level. The tongues of the glaciers are descending from elevated plateaus down into narrow valleys which were formed during the last ice age. This color image was produced in C-band using multi-polarization information (red=CHV, green=CVV,blue=CVV/CHV). The blue areas are lakes (Gepatsch dam at center right; Lake Muta at top right) and glacier ice. The yellow areas are slopes facing the radar and areas of dry snow. Purple corresponds to slopes facing away from the radar. Yellow in the valley bottom corresponds to tree covered areas. There is 30 to 50 centimeters (12 to 20 inches) of dry, fresh snow on the glaciers, and about 10 centimeters (4 inches) in the valley at the city of Vent, Austria (center). At these data were taken, the weather was cold, with snow and thick fog. The entire area would appear white to an optical sensor because it is all covered under a winter snowpack. Researchers are interested in Oetztal because knowing how glaciers shrink and grow over time is an important indication of climatic change. Spaceborne Imaging Radar-C and X-Synthetic Aperture Radar (SIR-C/X-SAR) is part of NASA's Mission to Planet Earth (MTPE). The radars illuminate Earth with

  2. Evaluation of groundwater droughts in Austria

    Droughts are abnormally dry periods that affect various aspects of human life on earth, ranging from negative impacts on agriculture or industry, to being the cause for conflict and loss of human life. The changing climate reinforces the importance of investigations into this phenomenon. Various methods to analyze and classify droughts have been developed. These include drought indices such as the Standard Precipitation Index SPI, the Palmer Drought Severity Index PDSI or the Crop Moisture Index CMI. These and other indices consider meteorological parameters and/or their effects on soil moisture. A depletion of soil moisture triggered by low precipitation and high evapotranspiration may also cause reduced groundwater recharge and thus decreasing groundwater levels and reduced groundwater flow to springs, streams, and wetlands. However, the existing indices were generally not designed to address such drought effects on groundwater. Thus, a Standardized Groundwater level Index has recently been proposed by Bloomfied and Marchant (2013). Yet, to our knowledge, this approach has only been applied to consolidated aquifers in the UK. This work analyzes time series of groundwater levels from various, mostly unconsolidated aquifers in Austria in order to characterize the effects of droughts on aquifers in different hydrogeologic and climatic settings as well as under different usage scenarios. In particular, comparisons are made between the water rich Alpine parts of Austria, and the dryer parts situated in the East. The time series of groundwater levels are compared to other data, such as meteorological time series and written weather records about generally accepted phenomena, such as the 2003 European drought and heat wave. Thus, valuable insight is gained into the propagation of meteorological droughts through the soil and the aquifer in different types of hydrogeologic and climatic settings, which provides a prerequisite for the assessment of the aquifers' drought

    This commentary discusses the decision in S.H. and Others v. Austria from a political theoretical and bioethical perspective. I focus on the opinion's discussion of what I call 'circumvention tourism', travelling abroad for the purpose of circumventing domestic prohibitions, especially as to medical services. The majority opinion in the case touts Austria's allowance of circumvention tourism for reproductive technology services that are illegal on Austrian soil as a reason to find as lawful Austria's prohibition on using those services on Austrian soil. To the contrary, I show that, in many ways, permitting circumvention tourism for these services while prohibiting them domestically is deeply problematic.

    This paper reports very generally on changes in the situation of women in physics in Austria since 2008 and more specifically on a national web-based survey that was distributed among physicists in Austria. It was aimed at understanding why few women are motivated to study physics and to follow an academic path. Family responsibilities— among others—seem to have a deep impact on women's careers. In Austria, initiatives to support women in scientific careers are quite well known throughout the physics community, and a high percentage of women responding to the survey said they had participated in at least one of them.

    Soil organic matter (SOM) is the major factor affecting sequestration of heavy metals in soil. The mean free binding energy and the mean free adsorption energy and speciation of Zn in soil, as affected by SOM, were determined by employing Wien effect measurements. The presence of SOM markedly decreased the Zn binding energy in soils in the following order: Top (5.86 kJ mol(-1)) < Bottom (8.66 kJ mol(-1)) < Top OM-free (9.44 kJ mol(-1)) ≈ Bottom OM-free (9.50 kJ mol(-1)). The SOM also significantly decreased the adsorption energy of Zn on black soil particles by reducing nonspecific adsorption of Zn on their surfaces. The speciation of Zn in soils was elucidated by extended X-ray absorption fine structure spectroscopy and microfocus X-ray fluorescence. The results obtained by linear combination fitting of EXAFS spectra revealed that the main forms of Zn in soil were outer-sphere Zn, Zn-illite, Zn-kaolinite, and HA-Zn. As the SOM content increased, the proportion of HA-Zn among the total immobilized Zn increased, and the proportion of nonspecific adsorbed Zn decreased. The present results implied that SOM is an important controlling factor for the environmental behavior of Zn in soils.

    Suicide rates exceed fatal traffic accidents two-fold in Austria but have been decreasing since 1987. Against common perceptions, approximately 75 % of all suicides in Austria are commited by men each year and while suicide attempts are more common in adolescents, completed suicides increase with age. Studies show that suicide rates are more common in rural than in urban areas and are associated with socio-economic factors. Nationwide prevention efforts should keep these epidemiological aspects in mind. PMID:23055303

    In Austria, vaccination coverage against Bordetella pertussis infections during infancy is estimated at around 90%. Within the last years, however, the number of pertussis cases has increased steadily, not only in children but also in adolescents and adults, indicating both insufficient herd immunity and vaccine coverage. Waning immunity in the host and/or adaptation of the bacterium to the immunised hosts could contribute to the observed re-emergence of pertussis. In this study we therefore addressed the genetic variability in B. pertussis strains from several Austrian cities. Between the years 2002 and 2008, 110 samples were collected from Vienna (n = 32), Linz (n = 63) and Graz (n = 15) by nasopharyngeal swabs. DNA was extracted from the swabs, and bacterial sequence polymorphisms were examined by MLVA (multiple-locus variable number of tandem repeat analysis) (n = 77), by PCR amplification and conventional Sanger sequencing of the polymorphic regions of the prn (pertactin) gene (n = 110), and by amplification refractory mutation system quantitative PCR (ARMS-qPCR) (n = 110) to directly address polymorphisms in the genes encoding two pertussis toxin subunits (ptxA and ptxB), a fimbrial adhesin (fimD), tracheal colonisation factor (tcfA), and the virulence sensor protein (bvgS). Finally, the ptxP promoter region was screened by ARMS-qPCR for the presence of the ptxP3 allele, which has been associated with elevated production of pertussis toxin. The MLVA analysis revealed the highest level of polymorphisms with an absence of MLVA Type 29, which is found outside Austria. Only Prn subtypes Prn1/7, Prn2 and Prn3 were found with a predominance of the non-vaccine type Prn2. The analysis of the ptxA, ptxB, fimD, tcfA and bvgS polymorphisms showed a genotype mixed between the vaccine strain Tohama I and a clinical isolate from 2006 (L517). The major part of the samples (93%) displayed the ptxP3 allele. The consequences for the vaccination strategy are discussed.

Considering the very shallow facies of the Upper Pannonian deposits and compared to fold structures documented in the neighbouring coal mine of Neufeld (Häusler, 2012b), the geophysical investigations of these buckling structures support the hypothesis of a tectonic origin.

    Acanthamoebae are the causative agents of an often seriously progressing keratitis (AK) occurring predominantly in contact lens wearers and can cause several disseminating infections potentially resulting in granulomatous amoebic encephalitis (GAE) in the immunocompromised host. Our institution is the Austrian reference laboratory for Acanthamoeba diagnostics and the aim of this study was to give an overview of proven cases of Acanthamoeba infections in Austria during the past 20 yr. All samples of patients with suspected AK or GAE were screened for Acanthamoeba spp. by culture and/or PCR and the detected amoebae were genotyped. Altogether, 154 cases of AK and three cases of GAE were diagnosed. Age of the AK patients ranged from 8 to 82 yr (mean 37.8) and 58% of the patients were female. Approximately 89% of the AK patients were contact lens wearers, almost all cases were unilateral and 19% of the patients required a keratoplasty. Age of the GAE patients ranged from 2 to 25 yr (mean 14.7), all were HIV-negative, but two were severely immunosuppressed at the time of diagnosis. The predominant genotype in the AK cases was T4, other genotypes found were T3, T5, T6, T10 and T11. The three GAE cases involved genotypes T2, T4 and T5.

    The possible existence of autochthonous sandfly populations in Central Europe north of the Alps has long been excluded. However, in the past years, sandflies have been documented in Germany, Belgium, and recently, also in Austria, close to the Slovenian border. Moreover, autochthonous human Leishmania and Phlebovirus infections have been reported in Central Europe, particularly in Germany. From 2010 to 2012, sandfly trapping (740 trap nights) was performed at 53 different capture sites in Austria using battery-operated CDC miniature light traps. Sites were chosen on the basis of their climate profile in the federal states Styria, Burgenland, and Lower Austria. Sandfly specimens found were transferred to 70% ethanol for conservation. Identification was based on morphological characters of the male genitalia and the female spermathecae, respectively. Altogether, 24 specimens, 22 females and 2 males, all identified as Phlebotomus (Transphlebotomus) mascittii Grassi, 1908, were found at six different sampling sites in all three federal states investigated. The highest number of catches was made on a farm in Lower Austria. Altogether, the period of sandfly activity in Austria was shown to be much longer than presumed, the earliest capture was made on July 3rd and the latest on August 28th. Sandflies have been autochthonous in Austria in small foci probably for long, but in the course of global warming, further spreading may be expected. Although P. mascittii is only an assumed vector of Leishmania spp.-data on its experimental transmission capacity are still lacking-the wide distribution of sandflies in Austria, a country thought to be free of sandflies, further supports a potential emergence of sandflies in Central Europe. This is of medical relevance, not only with respect to the transmission of Leishmania spp. for which a reservoir is given in dogs, but also with respect to the phleboviruses.

    This is a digital elevation model that was geometrically coded directly onto an X-band seasonal change image of the Oetztal supersite in Austria. The image is centered at 46.82 degrees north latitude and 10.79 degrees east longitude. This image is located in the Central Alps at the border between Switzerland, Italy and Austria, 50 kilometers (31 miles) southwest of Innsbruck. It was acquired by the Spaceborne Imaging Radar-C/X-band Synthetic Aperture aboard the space shuttle Endeavour on April 14, 1994 and on October 5, 1994. It was produced by combining data from these two different data sets. Data obtained in April is green; data obtained in October appears in red and blue, and was used as an enhancement based on the ratio of the two data sets. Areas with a decrease in backscatter from April to October appear in light blue (cyan), such as the large Gepatschferner glacier seen at the left of the image center, and most of the other glaciers in this view. A light blue hue is also visible at the east border of the dark blue Lake Reschensee at the upper left side. This shows a significant rise in the water level. Magenta represents areas with an increase of backscatter from April 10 to October 5. Yellow indicates areas with high radar signal response during both passes, such as the mountain slopes facing the radar. Low radar backscatter signals refer to smooth surface (lakes) or radar grazing areas to radar shadow areas, seen in the southeast slopes. The area is approximately 29 kilometers by 21 kilometers (18 miles by 13.5 miles). The summit of the main peaks reaches elevations of 3,500 to 3,768 meters (xx feet to xx feet)above sea level. The test site's core area is the glacier region of Venter Valley, which is one of the most intensively studied areas for glacier research in the world. Research in Venter Valley (below center)includes studies of glacier dynamics, glacier-climate regions, snowpack conditions and glacier hydrology. About 25 percent of the core test

    To gain deeper insight into the epidemiology of HIV-1 transmission in South-East Austria we performed a retrospective analysis of 259 HIV-1 partial pol sequences obtained from unique individuals newly diagnosed with HIV infection in South-East Austria from 2008 through 2014. After quality filtering, putative transmission linkages were inferred when two sequences were ≤1.5% genetically different. Multiple linkages were resolved into putative transmission clusters. Further phylogenetic analyses were performed using BEAST v1.8.1. Finally, we investigated putative links between the 259 sequences from South-East Austria and all publicly available HIV polymerase sequences in the Los Alamos National Laboratory HIV sequence database. We found that 45.6% (118/259) of the sampled sequences were genetically linked with at least one other sequence from South-East Austria forming putative transmission clusters. Clustering individuals were more likely to be men who have sex with men (MSM; p<0.001), infected with subtype B (p<0.001) or subtype F (p = 0.02). Among clustered males who reported only heterosexual (HSX) sex as an HIV risk, 47% clustered closely with MSM (either as pairs or within larger MSM clusters). One hundred and seven of the 259 sequences (41.3%) from South-East Austria had at least one putative inferred linkage with sequences from a total of 69 other countries. In conclusion, analysis of HIV-1 sequences from newly diagnosed individuals residing in South-East Austria revealed a high degree of national and international clustering mainly within MSM. Interestingly, we found that a high number of heterosexual males clustered within MSM networks, suggesting either linkage between risk groups or misrepresentation of sexual risk behaviors by subjects.

    Today, at a ceremony in Vienna, the Austrian Minister for Science and Research, Johannes Hahn and the ESO Director General, Tim de Zeeuw, signed the formal Accession Agreement between Austria and ESO, paving the way for Austria to join ESO as its 14th member state by 1 July this year. Signing Austria Agreement ESO PR Photo 20a/08 The Signing Ceremony "This will not only give the high-quality Austrian astronomical community full access to ESO's facilities, it will give Austrian scientists a say, together with their colleagues from the other member-states, in shaping the future of our science," said Tim de Zeeuw. The signing of the Agreement followed the unanimous approval by the ESO Council during its meeting in Prague on 3 June and the decision by the Austrian Government on 25 June. At the ceremony, Minister Hahn emphasised that the accession of Austria to ESO is a strong commitment to fundamental research and particularly to astronomy. "This sustainable investment enables Austrian science to gain access to a leading, international research infrastructure, and provides an important impulse for the attractiveness of Austria as a place for research," he said. "With the signature of the agreement today we bring a long discussion to a happy end and Austrian astronomy to new horizons." Since the Agreement means accession to an international convention, the agreement must now be submitted to the Austrian Parliament for ratification. "It is not possible to plan for radical changes, but ideal conditions will be created by this accession, which will strengthen Austrian and European astronomy. It is now for the scientists to use this opportunity," concluded the Austrian Minister.

  5. Autochthonous Leptospirosis in South-East Austria, 2004–2012

    Background Leptospirosis is one of the world’s mostly spread zoonoses causing acute fever. Over years, leptospirosis has been reported to occur rarely in Austria and Germany (annual incidence of 0.06/100,000 in Germany). Only imported cases have been on the increase. Objectives of this case-series study were to retrospectively assess epidemiologic and clinical characteristics of leptospirosis illnesses in South-East Austria, to describe risk exposures for autochthonous infections, and to compare patients with imported versus autochthonous infection. Methodology/Principal Findings During the 9-year period between 2004 and 2012, 127 adult patients (49 females, 78 males) who tested positive by rapid point-of-care test for Leptospira-specific IgM (Leptocheck®) were identified through electronic hospital databases. Follow-up telephone interviews were conducted with 82 patients. A total of 114 (89.8%) of the 127 patients enrolled had acquired leptospirosis within Austria and 13 (10.2%) had potentially imported infections. Most autochthonous cases were diagnosed during the months of June and July, whereas fewest were diagnosed during the winter months. Exposure to rodents, recreational activities in woods or wet areas, gardening, cleaning of basements or huts were the most common risk exposures found in autochthonous infection. Serogroups Australis (n = 23), Sejroe (n = 22), and Icterohaemorrhagiae (n = 11) were identified most frequently by MAT testing in autochthonous infections. Patients with imported leptospirosis were significantly younger, less likely to be icteric and had significantly lower liver transaminase levels (p = 0.004) than those with autochthonous infections. Conclusions/Significance Leptospirosis is endemic in South-East Austria. In contrast to reports from other countries we found a relatively high proportion of leptospirosis cases to be female (39% vs. ∼10%), likely the result of differing risk exposures for South-East Austria

  6. Paleo-Ice flow and overdeepenings in an Alpine setting: Examples from the Tyrolian Alps (Austria)

    surveys, a model of the LGM ice flow, its variation and its effect on glacial erosion is developed. On the one hand the effect of topography on ice dynamics in terms of promoting ice build-up as well as restricting erosion is evident. For the tributary valleys, on the other hand, the biggest amount of glacial erosion most probably occurred during the phase of ice build-up. However, seismic data, especially seismic stratigraphy (Reitner et al., 2007), shows the limitations of paleo-glaciological models derived from the youngest sequence, in this case the LGM sequence, for explaining sedimentary remnants of older glaciations. According to our example shifts of, and changes in, the amount of glacial erosion in tributary valleys may best be explained by changes in the onset of ice transfluences during ice build-up. Hence, a step-by-step lowering of passes and cols (water divides) during pleniglacial conditions had a profound impact on the ice dynamics of the following glaciation and, thus, on the occurrence of overdeepenings. Our model for a dynamic evolution of morphology presents an inverse relationship between the shaping of the surface and the subsurface and may only hold for a restricted area. However, this non-static view on glacier constellation and its change through time can explain the occurrence of unexpected overdeepenings or changes in erratic clast content elsewhere in dissected, formerly glaciated, Alpine landscapes.

    S. Wiens and A. Ohman (2002) disputed the conclusion that Pavlovian conditioning is strongly related to contingency awareness (P. F. Lovibond & D. R. Shanks, 2002) on the basis that an inappropriate definition of awareness was used. J. R. Manns, R. E. Clark, and L. R. Squire (2002) contended that delay eyeblink conditioning is independent of awareness. The authors of the present article consider these arguments, highlight several problems in the new studies described by the commentators, and conclude that there is still little evidence for unconscious conditioning in either subliminal autonomic conditioning or eyeblink conditioning. The most parsimonious account of existing data is that a single learning process gives rise to both awareness and conditioned responding. Further progress in evaluating the possibility of unconscious conditioning would be facilitated by the development of more completely specified and testable dual-process models.

    Leprosy used to be a widespread, dreaded disease in Europe during the middle ages, and it still remains an important health problem in some parts of the world today. Herein, we present data on the earliest 'Austrian' (an adult female from the early medieval period) proven to have suffered from leprosy. Manifestations of the disease were first identified during a systematic screening of pathological changes in skeletons recovered from an archaeological site in Pottenbrunn (Lower Austria). In the present study, DNA extracts from selected cranial and postcranial bone samples were investigated using polymerase chain reaction primers specific to the Mycobacterium leprae (M. leprae) repetitive element (RLEP). M. leprae traces were detected in extracts from nasal and palatine bones. Sequence analysis of informative polymorphic sites supports previous reports indicating that European M. leprae strains fall into single nucleotide polymorphism group 3. In summary, these findings put Austria on the map of confirmed leprosy cases in ancient Europe.

    From January to October 1992 24 Neisseria gonorrhoeae isolates from clinical specimens were collected at the Federal Public Health Laboratory in Innsbruck (Austria) and screened for resistance to penicillin G, erythromycin, tetracycline, spectinomycin, ceftriaxone, cefuroxime, ciprofloxacine, and silver nitrate. Patients originated from the Austrian provinces Salzburg, Tirol, and Vorarlberg, and presented with manifest gonorrhoea. Two of 24 isolates were penicillinase-producing N. gonorrhoeae. Both strains were isolated from men who had just returned from Thailand or Kenya. The isolate from Africa was also resistant to tetracycline. Five of 24 infections were acquired abroad, sex tourism being involved in four cases. The antimicrobial resistance pattern found in gonococci in western Austria revealed that topical silver nitrate and erythromycin are equally acceptable for use in prophylaxis of neonatal ophthalmia. Penicillin is still the drug of choice in the treatment of endemic infections. If gonorrhoea has been acquired abroad, especially in Asia or Africa, ceftriaxone, spectinomycin or ciprofloxazine are recommended for therapy. PMID:8333204

    While standard economic theory posits that privately owned hospitals are more efficient than their public counterparts, no clear conclusion can yet be drawn for Austria in this regard. As previous Austrian efficiency studies rely on data from the 1990s only and are based on small hospital samples, the generalizability of these results is questionable. To examine the impact of ownership type on efficiency, we apply a Data Envelopment Analysis which extends the existing literature in two respects: first, it evaluates the efficiency of the Austrian acute care sector, using data on 128 public and private non-profit hospitals from the year 2010; second, it additionally focusses on the inpatient sector alone, thus increasing the comparability between hospitals. Overall, the results show that in Austria, private non-profit hospitals outperform public hospitals in terms of technical efficiency. A multiple regression analysis confirms the significant association between efficiency and ownership type. This conclusive result contrasts some international evidence and can most likely be attributed to differences in financial incentives for public and private non-profit hospitals in Austria. Therefore, by drawing on the example of the Austrian acute care hospital sector and existing literature on the German acute care hospital sector, we also discuss the impact of hospital financing systems and their incentives on efficiency. This paper thus also aims at providing a proof of principle, pointing out the importance of the respective market conditions when internationally comparing hospital efficiency by ownership type.

    The reform of psychiatric services in Austria started during the second half of the seventies of the 20th century. During the early phase the reform focussed on dehospitalization and principles of community psychiatry. About 60% of psychiatric hospital beds were closed and the size of psychiatric hospitals was reduced. One of the psychiatric hospitals was closed and psychiatric departments were opened as part of district general hospitals. During this time the number of psychiatric hospital admissions increased markedly and a large proportion of mentally ill are treated as inpatients in non-psychiatric wards. Only about a fifth of self-employed psychiatrists working in their own office have a contract with health insurances. In Austria, the number of psychotherapists is much higher than the number of psychiatrist. A variety of different types of community services provide social and vocational rehabilitation, focussing on consultation, housing, daily structure and employment. Psychiatric services are nowadays fragmented into a number of sub-disciplines such as psychosomatics or child and adolescent psychiatry. This fragmentation and the missing coordination of psychiatric services hamper the enhancements of psychiatric care. This complicates the development of integrated services, i.e. the structured and planned cooperation of the different types of services. Since there are no binding rules for the organisation and planning in entire Austria, financing and organisation of services is fragmented. For establishing an integrated health care, coordination and cooperation between providers, sponsors of health care as well as policy makers are essential.

    We report five consecutive cases of Anaplasma (A.) phagocytophilum infection (the causative agent of human granulocytic anaplasmosis (HGA)) from western Austria. All infections were acquired between June and August in 2003 and 2004 in the Inn valley (Tyrol, Austria). Four patients required hospitalisation, one patient was treated as an outpatient. During the acute stage of illness, laboratory findings included thrombocytopenia (5/5), elevated C-reactive protein (5/5), elevated neopterin (5/5), elevated lactate dehydrogenase (4/5), and elevation of liver enzymes (4/5). Leukopenia (3/5) and elevated procalcitonin (2/5) were less frequently observed. All patients were treated with tetracyclines, which led to prompt improvement of the clinical conditions. Anti-platelet antibodies were observed in one of four patients, but remained unchanged after complete covalescence.

The Austrian Red Cross Blood Service (ARC-BS) started a first voluntary screening for WNV in blood donors from Eastern Austria by Nucleic Acid Testing (NAT) in June 2014. This is also the most extensive WNV surveillance programme in humans in Austria so far. In August 2014, one autochthonous WNV infection was detected in a blood donor from Vienna. By now, one in 67,800 whole blood donations was found to be positive for WNV RNA.

    Rodents are important reservoirs for a large number of zoonotic pathogens. We examined the occurrence of 11 viral, bacterial, and parasitic agents in rodent populations in Austria, including three different hantaviruses, lymphocytic choriomeningitis virus, orthopox virus, Leptospira spp., Borrelia spp., Rickettsia spp., Bartonella spp., Coxiella burnetii, and Toxoplasma gondii. In 2008, 110 rodents of four species (40 Clethrionomys glareolus, 29 Apodemus flavicollis, 26 Apodemus sylvaticus, and 15 Microtus arvalis) were trapped at two rural sites in Lower Austria. Chest cavity fluid and samples of lung, spleen, kidney, liver, brain, and ear pinna skin were collected. We screened selected tissue samples for hantaviruses, lymphocytic choriomeningitis virus, orthopox viruses, Leptospira, Borrelia, Rickettsia, Bartonella spp., C. burnetii, and T. gondii by RT-PCR/PCR and detected nucleic acids of Tula hantavirus, Leptospira spp., Borrelia afzelii, Rickettsia spp., and different Bartonella species. Serological investigations were performed for hantaviruses, lymphocytic choriomeningitis virus, orthopox viruses, and Rickettsia spp. Here, Dobrava-Belgrade hantavirus-, Tula hantavirus-, lymphocytic choriomeningitis virus-, orthopox virus-, and rickettsia-specific antibodies were demonstrated. Puumala hantavirus, C. burnetii, and T. gondii were neither detected by RT-PCR/PCR nor by serological methods. In addition, multiple infections with up to three pathogens were shown in nine animals of three rodent species from different trapping sites. In conclusion, these results show that rodents in Austria may host multiple zoonotic pathogens. Our observation raises important questions regarding the interactions of different pathogens in the host, the countermeasures of the host's immune system, the impact of the host-pathogen interaction on the fitness of the host, and the spread of infectious agents among wild rodents and from those to other animals or humans.

    Groundwater is the most important source for drinking water in Austria. In some parts of Southern Austria water resources already are very vulnerable to unfavourable climate conditions. This paper summarizes case studies of estimating the impact of climate change on groundwater recharge and groundwater flow in Southern Austria in the frame of the ETC-Alpine Space project ALP-WATER-SCARCE. In several pilot regions a distributed hydrological model was set up to simulate groundwater recharge and groundwater flow for a period of 10 to 30 years. The pilot sites range from mountainous catchments with steep hillslopes to Alpine valleys and flatlands with pore aquifers. In the model period comprehensive land data and meteorological data were used, and the models were calibrated to available stream gauge data. Additional low flow monitoring in the frame of the project also allowed for a more detailed regional analysis in some catchments. The simulations were firstly used to extend runoff and groundwater recharge depths on an annual basis up to 200 years into the past by regression analysis with long time meteorological parameters (HISTALP). The historical view shows that groundwater flow and recharge in most of the pilot regions decreased since the beginning of the 20th century, which is mainly the effect of climate change. Changes of land use are of minor relevance in most of the regions. Second, by the calibrated model scenarios were simulated to quantify the impact of a possible future change in the climatic conditions on water resources. The scenarios were generated by altering the model input by a "Delta-Change", under consideration of the historical development. These scenarios can be interpreted as "what if"-scenarios to quantify the sensitivity of the hydrological systems on these climatic variables. The results are compared with actual and projected water uses as a basis for regional water resources management.

    In Austria energy wood production in short rotation coppice systems (SRC) becomes increasingly important to meet the demands of the growing bio-energy sector. In order to successfully develop the SRC market, the achievement of high and constant yields in SRC management is just as important as a reliable harvesting technology, which facilitates the production of high quality wood chips. Yield models and site-specific knowledge about productivity are needed with respect to clones, site factors and management alternatives. Therefore in the years 2007 and 2008 experimental plots (Marchfeld; 16 poplar clones and 19 willow clones) and a network of demonstration plots (different regions in Lower Austria; 7 poplar clones, 4 willow clones) were established. Single shoot surveys and biomass functions in combination with stand inventories form the general basis for estimating yield and productivity. They also help to optimize yield and rotation length by taking the maximum harvestable tree diameter into account, which is determined by harvesting techniques. For optimizing the yield estimation of SRC stands, preliminary clone specific yield functions for poplar and willow clones were developed. These specific yield functions were based on common yield estimation functions with respect to the newly used clones (e.g. faster growth, lower wood density), using a regression analytical approach. Standard stand surveys were carried out in autumn 2007, 2008, 2009 and 2010. We were able to show a high variety in biomass production of poplar and willow clones on the specific site. For the first and second rotation cycle the mean productivity of poplar clones was within a range of 4 - 12 t/y/ha and for willow clones within a range of 3 - 17 t/y/ha. These results were compared with the productivity of older experimental plots in Austria. Based on the preliminary results of productivity of poplar and willow clones for various site factors and management alternatives (planting design

    Abstract Rodents are important reservoirs for a large number of zoonotic pathogens. We examined the occurrence of 11 viral, bacterial, and parasitic agents in rodent populations in Austria, including three different hantaviruses, lymphocytic choriomeningitis virus, orthopox virus, Leptospira spp., Borrelia spp., Rickettsia spp., Bartonella spp., Coxiella burnetii, and Toxoplasma gondii. In 2008, 110 rodents of four species (40 Clethrionomys glareolus, 29 Apodemus flavicollis, 26 Apodemus sylvaticus, and 15 Microtus arvalis) were trapped at two rural sites in Lower Austria. Chest cavity fluid and samples of lung, spleen, kidney, liver, brain, and ear pinna skin were collected. We screened selected tissue samples for hantaviruses, lymphocytic choriomeningitis virus, orthopox viruses, Leptospira, Borrelia, Rickettsia, Bartonella spp., C. burnetii, and T. gondii by RT-PCR/PCR and detected nucleic acids of Tula hantavirus, Leptospira spp., Borrelia afzelii, Rickettsia spp., and different Bartonella species. Serological investigations were performed for hantaviruses, lymphocytic choriomeningitis virus, orthopox viruses, and Rickettsia spp. Here, Dobrava-Belgrade hantavirus-, Tula hantavirus-, lymphocytic choriomeningitis virus-, orthopox virus-, and rickettsia-specific antibodies were demonstrated. Puumala hantavirus, C. burnetii, and T. gondii were neither detected by RT-PCR/PCR nor by serological methods. In addition, multiple infections with up to three pathogens were shown in nine animals of three rodent species from different trapping sites. In conclusion, these results show that rodents in Austria may host multiple zoonotic pathogens. Our observation raises important questions regarding the interactions of different pathogens in the host, the countermeasures of the host's immune system, the impact of the host–pathogen interaction on the fitness of the host, and the spread of infectious agents among wild rodents and from those to other animals or humans.

    The main objective of the paper is to understand the contributions to the uncertainty in low flow projections resulting from hydrological model uncertainty and climate projection uncertainty. Model uncertainty is quantified by different parameterizations of a conceptual semi-distributed hydrologic model (TUWmodel) using 11 objective functions in three different decades (1976-1986, 1987-1997, 1998-2008), which allows disentangling the effect of modeling uncertainty and temporal stability of model parameters. Climate projection uncertainty is quantified by four future climate scenarios (ECHAM5-A1B, A2, B1 and HADCM3-A1B) using a delta change approach. The approach is tested for 262 basins in Austria. The results indicate that the seasonality of the low flow regime is an important factor affecting the performance of model calibration in the reference period and the uncertainty of Q95 low flow projections in the future period. In Austria, the calibration uncertainty in terms of Q95 is larger in basins with summer low flow regime than in basins with winter low flow regime. Using different calibration periods may result in a range of up to 60 % in simulated Q95 low flows. The low flow projections show an increase of low flows in the Alps, typically in the range of 10-30 % and a decrease in the south-eastern part of Austria mostly in the range -5 to -20 % for the period 2021-2050 relative the reference period 1976-2008. The change in seasonality varies between scenarios, but there is a tendency for earlier low flows in the Northern Alps and later low flows in Eastern Austria. In 85 % of the basins, the uncertainty in Q95 from model calibration is larger than the uncertainty from different climate scenarios. The total uncertainty of Q95 projections is the largest in basins with winter low flow regime and, in some basins, exceeds 60 %. In basins with summer low flows and the total uncertainty is mostly less than 20 %. While the calibration uncertainty dominates over climate

    A large majority of Austrian citizens are aware of tick-borne encephalitis (TBE), consequently reflected by a high vaccination rate of 85%. In return, risk assessment and disease mapping on human cases might be hampered due to high and inhomogeneous vaccination rates and travel habitats of humans. The roe deer was used to obtain a starting point for the integral view on the actual risk of TBE in Austria. The roe deer exhibits several attributes which makes it suitable as an indicator species: the roe deer has a restricted home range and it is known to be a heavy tick carrier. Furthermore it sero-converts after infection with TBE, but no outbreak occurs. Sera from 945 roe deer were obtained from all over Austria and screened with IFAT for the antibodies against TBE. Twenty-two positive samples, 2.4%, and 17 samples at the borderline titre of 1:16 were identified. The majority of the positive samples, 70.6%, were located in known TBE areas based on human cases. Further research is needed to confirm or reject new endemic foci of TBE transmission. PMID:25869034

    In situ gamma-spectrometry has become a useful method of assessing the nuclide concentrations of man-made and natural gamma-emitters in the soil. For the quality assurance of the measurements, periodically conducted intercomparison exercises are essential. Therefore exercises were organized in different European countries since 1990, the last one was conducted in Salzburg, Austria in September 1994. The participation of 27 measurement teams from all over Europe emphasizes the importance of the intercomparison. Salzburg was selected because the Province of Salzburg, Austria was among the most heavily contaminated regions outside the former USSR by the Chernobyl fallout. Two different typical sites were selected for the measurements: Site 1 was inside the urban area of Salzburg on intensively used grassland which had not been tilled since the deposition of the fallout. This site is representative for intensively used agricultural regions in the Province of Salzburg. Site 2 was in the mountainous regions of the Hohe Tauern at an elevated altitude of 1600 m, representing the agricultural soil- and contamination conditions of the Alpine regions in the Tauern. The two sites differ significantly in terms of soil characteristics, a crucial parameter for the evaluation of in situ gamma-spectra. The participants used different approaches for the evaluation of the gamma-spectra in terms of considering the depth distribution. In the paper the results from the 24 European teams are presented.

    2013-01-01

    Background Preventive health check-ups in Austria are offered free of charge to all insured adults (98% of the population) and focus on early detection of chronic diseases, primary prevention, and health counseling. The study aims to explore predictors of compliance with the recommended interval of preventive health check-up performance. Methods Source of data was the Austrian Health Interview Survey 2006/07 (15,474 subjects). Participation in a preventive health examination during the last three years was used as dependent variable. Socio-demographic and health-related characteristics were used as independent variables in a multivariate logistic regression analysis. Results Results show that 41.6% of men and 41.8% of women had attended a preventive health check-up within the last three years. In multivariate analysis, subjects ≥40 years, with higher education, higher income or born in Austria were significantly more likely to attend a preventive health check-up. Furthermore, a chronic disease was associated with a higher attendance rate (OR: 1.21; CI: 1.07-1.36 in men; OR: 1.19; CI: 1.06-1.33 in women). Conclusions Attendance rates for health check-ups in the general Austrian population are comparatively high but not equally distributed among subgroups. Health check-ups must increase among people at a young age, with a lower socio-economic status, migration background and in good health. PMID:24308610

    We report on the first documented outbreak of leptospirosis in Austria. In July 2010, four cases of serologically confirmed leptospirosis occurred in athletes after a triathlon held in Langau. Heavy rains preceded the triathlon (rainfall: 22 mm). The index case (Patient A) was a 41-year-old previously healthy male, who was admitted to hospital A on July 8 with a four-day history of fever up to 40°C that began 14 days after attending the triathlon event. On July 7, patient B, a 42-year-old male, was admitted to the same hospital, with signs and symptoms of kidney failure. Hemodialysis was performed every other day for 3 weeks. While the serum drawn on the day of admission was negative for antibodies against Leptospira, a specimen from July 28 tested positive with Leptospira interrogans. On July 11, patient C, a 40-year-old male, was admitted to hospital B for nephritis. On July 14, patient D, a 44-year-old male, was admitted to hospital C with a ten days history of intermittent fever, mild dry cough and headache. Our report underlines that in Austria recreational users of bodies of freshwater must be aware of an existing risk of contracting leptospirosis, particularly after heavy rains. The suppressive influence of a triathlon on the immune system is well documented and therefore an outbreak in this population group can be seen as a sensitive indicator concerning possible risk for the general population.

    We present an almost 500-year May-July temperature reconstruction based on 24 biophysical series. 19 are vine-related series from Kőszeg, Szombathely and Sopron in Western Hungary (11 series, from 1580s onwards), Vienna, Klosterneuburg, Perchtoldsdorf (7 series; at present from 1520s onwards) in Eastern Austria and Bratislava in Western Slovakia (1 series, from 1770s onwards). At present, the first, largest group is the vine related indicators, where dates of blossoming (1 series), beginning of grape ripening (3 series), dates of full ripening (2 series), beginning of grapevine harvest (8 series), starting dates of pressing out the juice (1 series: at present 1520s onwards), starting dates of tax-collection (after the pressed juice: 1 series) and wine quality indices (3 series: from 1580s onwards) are also included. The second main group of 4 indicators applied in the analysis are grain-harvest related indicators from Western Hungary, such as dates for estimation of harvesting-shares which are strongly dependant on the beginning of grain harvesting (at present 2 series: from 1640s onwards) and dates of grain tax collection (2 series: from 1560s onwards). A third group, still in development, is mainly related to more natural vegetation, and is strongly dependent on the full ripening of oak acorns: the starting dates of woodland pasture (at present 1 series: from 1770s onwards). The above-mentioned historical series correlate well, over the 18th-19th century period, with Vienna May-July measured temperature (Böhm, et. al. 2009). The complicated nature of these historical data is described (e.g. with respect to the normality of the data distribution), and we present methods to transform and composite the data into a homogenous, homoscedastic time-series that can be used for proxy based calibration. Finally, a preliminary May-July temperature reconstruction is derived using modified dendrochronological methods. (see Leijonhufvud et al. 2009) The Kőszeg, Szombathely

    The successful marriage policy of margrave Leopold III increased the importance of the House of Babenberg in late medieval Austria (12th century). Historical documentation is inconclusive in providing evidence whether or not his eldest son Adalbert derived from an earlier relationship or from the marriage with King Henry IV's daughter Agnes of Waiblingen, with whom Leopold is considered to have had 17 children. As a matter of fact Adalbert was ignored in the line of succession in favor of a younger brother, Leopold IV, which has led to long term historical discussions. Human remains attributed to these individuals were subjected to DNA analysis. Autosomal, Y-chromosomal and mitochondrial DNA analyses brought successful results, which suggested that Leopold III, Agnes and Adalbert were related in parent-son constellation, in contrast to historical considerations. A possible mix-up of Adalbert's remains with those of his younger brother Ernst could not be confirmed by DNA analysis.

    1997-09-01

    As part of a long-term study of indoor air pollution, formaldehyde concentrations were determined in 792 apartments following complaints by inhabitants. Measurements were carried out using Draeger tubes as well as the acetyl acetone method. In 157 apartments, HCHO concentrations of more than 0.1 ppm, exceeding the recommended standard values for indoor air concentrations, were determined. The concentrations determined tended to decrease over time. As far as they were caused by furnishings, they were limited to the spaces where these furnishings were installed. In older-style prefabricated houses with foam-filled particle-board wall systems, concentrations of more than 1.0 ppm were determined. In spite of legal regulations governing the release of formaldehyde from substances, preparations and products containing formaldehyde which have been in existence in Austria since 1990, this substance must still be considered as a possible factor of indoor pollution in causing feelings of ill-health.

    In Austria, about a quarter of the population older than 60 years receives more than five medicines per quarter at the expense of the statutory health insurance. Especially for older and multimorbid people the risk of adverse drug reactions increases by taking multiple drugs. The social insurance has initiated activities to direct the focus on the issue of polypharmacy and the associated problems. An information campaign with the title "Vorsicht Wechselwirkung" has been developed which addresses physicians and patients. Tailored to the target groups, useful information and assistance should contribute to strengthening the awareness and compliance, and to improving the quality of drug therapies. To specifically sensitize general practitioners to the issue of polypharmacy, the "Poly-rate" is calculated. It is used as a parameter to assess the extent of polypharmacy in a physician's practice, and is being sent to general practitioners by the social insurance for information purposes. PMID:26847442

    In Austria, two recent eParticipation projects focused on adolescent citizens. The first project, “mitmachen.at - move your future” was to provide initial experiences with an eParticipation tool. The second project, “Jugend2help”, applied the lessons learned from the “mitmachen.at” project to improve the Austrian public administration web portal for adolescent citizens. In both projects, the results indicate that web portals and eParticpation seems to suit the adolescents’ information and communication needs. Involving the users is central to the development of an eParticipation process or platform so that the users’ specific characteristics (age, skills), needs and interests are included appropriately. The target users’ characteristics are also important for developing a marketing strategy which is able to reach them. Other issues which must also be considered in eParticipation are accessibility, inclusion and possibly gender.

    Kreisgrabenanlagen, monumental Neolithic circular enclosures, have been recorded in many places in central Europe. Some of them have been described as having entrances pointing to solar- or lunar-related declinations (e.g., solstices, lunistices). Over 40 KGAs have been found in Lower Austria, and the current ASTROSIM project investigates their potential astronomical use. Horizon data surveyed in the field are combined with previous results from geomagnetic prospection on a digital elevation model, and the reconstructed three-dimensional sceneries and virtual models can then be investigated for their astronomical potential. In contrast to a promising overview study, results for the Lower Austrian KGA are rather sobering in general, but there are a few solar-oriented entrances which can be demonstrated with newly-developed software.

  5. Alternative solutions for public and private catastrophe funding in Austria

    NASA Astrophysics Data System (ADS)

    Gruber, M.

    2008-07-01

    The impacts of natural hazards as well as their frequency of occurrence during the last decades have increased decisively. Therefore, the public as well as the private sector are expected to react to this development by providing sufficient funds, in particular for the improvement of protection measures and an enhanced funding of damage compensation for affected private individuals, corporate and public entities. From the public stance, the establishment of an appropriate regulatory environment seems to be indispensable. Structural and legal changes should, on the one hand, renew and improve the current distribution system of public catastrophe funds as well as the profitable investment of these financial resources, and on the other hand, facilitate the application of alternative mechanisms provided by the capital and insurance markets. In particular, capital markets have developed alternative risk transfer and financing mechanisms, such as captive insurance companies, risk pooling, contingent capital solutions, multi-trigger products and insurance securitisation for hard insurance market phases. These instruments have already been applied to catastrophic (re-)insurance in other countries (mainly the US and off-shore domiciles), and may contribute positively to the insurability of extreme weather events in Austria by enhancing financial capacities. Not only private individuals and corporate entities may use alternative mechanisms in order to retain, thus, to finance certain risks, but also public institutions. This contribution aims at analysing potential solutions for an improved risk management of natural hazards in the private and the public sector by considering alternative mechanisms of the capital and insurance markets. Also the establishment of public-private-partnerships, which may contribute to a more efficient cat funding system in Austria, is considered.

A detailed national model, obtained for the year 2013 through Material Flow Analysis, represents the reference situation. Applicability and limitations are discussed for a range of actions aimed at reducing consumption, increasing recycling, and lowering emissions. The potential contribution of each field of action is quantified and compared using three indicators: Import dependency, Consumption of fossil-P fertilizers and Emissions to water bodies. Further, the uncertainty of this assessment is characterized and priorities for the upgrade of data collection are identified. Moreover, all the potential gains discussed in the article are applied to the reference situation to generate an ideal target model. The results show that in Austria a large scope for phosphorus stewardship exists. Strategies based exclusively either on recycling or on the decline of P consumption hold a similar potential to reduce import dependency by 50% each. An enhanced P recycling from meat and bone meal, sewage sludge and compost could replace the current use of fossil-P fertilizers by 70%. The target model, i.e. the maximum that could be achieved taking into account trade-offs between different actions, is characterized by an extremely low import dependency of 0.23kgPcap(-1)y(-1) (2.2kgPcap(-1)y(-1) in 2013), by a 28% decline of emissions to water bodies and by null consumption of fossil-P fertilizers. This case study shows the added value of using Material Flow Analysis as a basis to design sound management strategies. The systemic approach inherent to it allows performing a proper comparative assessment of different actions, identifying priorities, and visualizing a target model. PMID:27177138

  7. Management of Disused Sealed Sources in Austria - 12147

    SciTech Connect

    Fischer, Helmut

    2012-07-01

    The use of sealed radiation sources is regulated by the Austrian Radiation Protection Act and the General Radiation Protection Ordinance. The Austrian radiation protection legislation requires minimisation of radioactive waste. The preferred radioactive waste management option concerning sealed sources, both spent and disused, is the return to the manufacturer. If this is not possible a reuse by a third party is encouraged. According to this requirement, disused sealed sources shall, as far as possible, be stored on the site of the licence holder until a new owner is found. If this is not possible, disused sealed sources shall be transported to Nuclear Engineering Seibersdorf, which is a recognised storage facility for radioactive waste in Austria, for temporary storage pending reuse. Sources, which cannot be reused, are declared as radioactive waste. Since Austria is a Member State of the European Union, the Council Directive 122/2003/Euratom on High Activity Sealed Sources and Orphan Sources is applied. This directive defines high activity sealed sources on the basis of their total activity. The possession of such sources is subject to certain obligations. Therefore it is in the interest of the owner to return disused sources as soon as possible to the manufacturer or to deliver them to Nuclear Engineering Seibersdorf. In case of the loss and finding of an 'orphan' source the competent authority secures, recovers and stores the source at the cost of the owner of the source with recourse. In line with the directive the licensee of a High Activity Sealed Source has to notify the main data concerning this source to the Central Source Register which is maintained by the Federal Minister of Agriculture, Forestry, Environment and Water Management for all radioactive sources. This register was put into operation in 2006. (authors)

    We present Hubble Space Telescope (HST) near-infrared photometry of the coldest known brown dwarf, WISE J085510.83-071442.5 (WISE 0855-0714). WISE 0855-0714 was observed with the Wide Field Camera 3 (WFC3) on board HST using the F105W, F125W, and F160W filters, which approximate the Y, J, and H near-infrared bands. WISE 0855-0714 is undetected at F105W with a corresponding 2σ magnitude limit of ˜26.9. We marginally detect WISE 0855-0714 in the F125W images (S/N ˜ 4), with a measured magnitude of 26.41 ± 0.27, more than a magnitude fainter than the J-band magnitude reported by Faherty et al. WISE J0855-0714 is clearly detected in the F160W band, with a magnitude of 23.86 ± 0.03, the first secure detection of WISE 0855-0714 in the near-infrared. Based on these data, we find that WISE 0855-0714 has extremely red {{F}}105{{W}}-{{F}}125{{W}} and {{F}}125{{W}}-{{F}}160{{W}} colors relative to other known Y dwarfs. We find that when compared to the models of Saumon et al. and Morley et al., the {{F}}105{{W}}-{{F}}125{{W}} and {{F}}125{{W}}-{{F}}160{{W}} colors of WISE 0855-0714 cannot be accounted for simultaneously. These colors likely indicate that we are seeing the collapse of flux on the Wien tail for this extremely cold object.

  9. Filicide in Austria and Finland - A register-based study on all filicide cases in Austria and Finland 1995-2005

    PubMed Central

    2009-01-01

    Background Filicide is the tragic crime of murdering one's own child. Previous research has found that the offending parents are commonly depressed and that suicide is often associated as an actual act or an intention. Yet, filicide is an underreported crime and previous studies have been strained with methodological problems. No comprehensive international studies on filicide have been presented in the literature until now. Methods This was a descriptive, comprehensive, register-based study of all filicides in Austria and Finland during 1995-2005. Filicide-suicide cases were also included. Results Most of the perpetrators were the biological mothers; in Austria 72%, in Finland 52%. Suicide followed filicide either as an attempt or a fulfilled act in 32% and 54% of the cases in Austria and Finland, respectively. Psychotic mood disorders were diagnosed for 10% of the living perpetrators in Austria, and 12% in Finland. Non-psychotic depression was diagnosed in 9% of surviving perpetrators in Austria, 35% in Finland. Conclusion The data from the two countries demonstrated that filicide is such a multifaceted and rare phenomenon that national data from individual countries seldom offer sufficient scope for its thorough study. Further analyses are needed to produce a complete picture of filicide. PMID:19930581

    This paper reports on the Austrian research project "Renewable energy in Austria: Modeling possible development trends until 2020". The project investigated possible economic and ecological effects of a substantially increased use of renewable energy sources in Austria. Together with stakeholders and experts, three different scenarios were defined, specifying possible development trends for renewable energy in Austria. The scenarios were simulated for the period 2006-2020, using the integrated environment-energy-economy model "e3.at". The modeling results indicate that increasing the share of renewable energy sources in total energy use is an important but insufficient step towards achieving a sustainable energy system in Austria. A substantial increase in energy efficiency and a reduction of residential energy consumption also form important cornerstones of a sustainable energy policy. PMID:21976785

  11. Evaluation of the operational Air-Quality forecast model for Austria ALARO-CAMx

    NASA Astrophysics Data System (ADS)

    Flandorfer, Claudia; Hirtl, Marcus

    2016-04-01

    The Air-Quality model for Austria (AQA) is operated at ZAMG by order of the regional governments of Vienna, Lower Austria, and Burgenland since 2005. The emphasis of this modeling system is on predicting ozone peaks in the North-east Austrian flatlands. The modeling system is currently a combination of the meteorological model ALARO and the photochemical dispersion model CAMx. Two modeling domains are used with the highest resolution (5 km) in the alpine region. Various extensions with external data sources have been conducted in the past to improve the daily forecasts of the model, e.g. data assimilation of O3- and PM10-observations from the Austrian measurement network (with optimum interpolation method technique), MACC-II boundary conditions; combination of high resolved emission inventories for Austria with TNO and EMEP data. The biogenic emissions are provided by the SMOKE model. The model runs 2 times per day for a period of 48 hours. ZAMG provides daily forecasts of O3, PM10 and NO2 to the regional governments of Austria. The evaluation of these forecasts is done for January to September 2015, with the main focus on the summer peaks of ozone. The measurements of the Air-Quality stations are compared with the punctual forecasts at the sites of the stations and the area forecasts for every province of Austria. Several heat waves occurred between June and September 2015 (new temperature records for St. Pölten and Linz). During these periods the information threshold for ozone has been exceeded 19 times, mostly in the Eastern regions of Austria. Values above the alert threshold have been measured at some stations in Lower Austria and Vienna at the beginning of July. For the evaluation, the results for the periods with exceedances in Eastern Austria will be discussed in detail.

    This paper offers a description of the e-Government Strategy in Austria and its e-Government readiness, and looks at how two different user groups are experiencing e-Government in Austria. Studies conducted show that adolescent citizens are more optimistic and enthusiastic about the possibilities offered whilst the municipalities are more skeptical. The Austrian e-Government strategy, the decisionmakers and IT solution providers must understand the needs of all stakeholders and provide viable solutions accordingly.

  13. Structural shifts in the employment of foreign workers in Austria.

    Biffl, G

    The full economic importance of immigration becomes clear only when one examines the concentration of immigrant workers in certain industries and occupations, and this is done in the case of Austria to show the degree of segmentation of the labor market between indigenous and foreign labor. In the course of the 1960s the employment of foreign labor gained importance in Austria. As a consequence, bilateral agreements with the major recruiting countries were made, e.g., with Spain in 1962 and 1969, with Turkey in 1964, and with Yugoslavia in 1966. The reason for the increasing demand for foreign labor was the short supply of indigenous labor due to increasing participation rates and strong economic growth. The demand-pull for foreign labor gained momentum with the onset of the economic boom in 1970, so that by the end of 1973 the number of foreign workers had doubled in comparison to 1970. The 226,800 foreign workers accounted for 8.7% of total employment. The 1974-75 recession and the weak economic development ever since resulted in a decreasing demand for labor. At the same time, the supply of indigenous labor increased as a consequence of a demographic effect and because of increasing participation rates of women. From 1981 to the present, foreign employment decreased again due to the unusually long period of economic stagnation. During 1983, 145,300 foreign workers were engaged, i.e., 5.3% of total employment. The structure for foreign employment now differs greatly from that in the 1960s. The share of women in foreign employment has increased steadily from some 20% in the early 1960s to 31% in 1973 and 40% in 1983 -- a value comparable to the Austrian female share in employment. The reduction of foreign employment since 1973 affected, above all, Yugoslav men. the share of Yugoslavs in foreign employment decreased from 196,300 or 79% in 1973 to 92,200 or 61.7% in 1983. With the duration of foreign employment rising, the disribution of foreign labor over economic

    Low pressure granulite facies rocks are commonly found in the Bohemian Massif in Upper Austria. They belong to the Moldanubian Unit and were metamorphosed during the last stage of the Variscan orogeny. The investigated granulites from the Donau valley (west of Linz), Lichtenberg (northwest of Linz), Sauwald (south of the river Danube) and Bad Leonfelden zone comprise mainly migmatic paragneisses. Most of these rocks underwent high degrees of melting forming meta- and diatexites (''Perlgneise)''. Al-rich metapelites with partly cm-sized garnet porphyroblasts, which are suitable for precise PT and PT-path determinations, can be found in some localities of this unit. In this study samples taken along the Danube valley between Linz and Wilhering, from Lichtenberg and from Bad Leonfelden (north of Linz) were sampled and investigated petrographically in detail. Since garnets are rare and usually consumed by cordierite, a sample with large garnets was investigated in detail. A chemical zoning profile across the c. 1cm large garnet displayed elevated Ca contents (Xgrs=0.06) in the central part which decreased discontinuously towards the rim to Xgrs=0.02. Almandine, pyrope and spessartine components do not show any pronounced zoning pattern. Most of the smaller garnet grains in other samples are also homogeneous in composition with a slight Xalm increase and Xprp decrease at the rims, typical for retrograde diffusional zoning. The cordierite-garnet-sillimanite-granulites as well as some mafic granulites were used for geothermobarometry. Metamorphic conditions of around 770°C to 850°C and 0.5-0.6 GPa could be obtained, which are similar to the values obtained by Tropper et al. (2006). P. Tropper I. Deibl F. Finger R. Kaindl (2006).

    Computing reference evapotranspiration and multiplying it with a specific crop coefficient as recommended by the Food and Agriculture Organization of the United Nations (FAO) is the most widely accepted approach to estimate plant water requirements. The standardized form of the well-known FAO Penman-Monteith equation, published by the Environmental and Water Resources Institute of the American Society of Civil Engineers (ASCE-EWRI), is recommended as a standard procedure for calculating reference evapotranspiration. Applied and validated under different climatic conditions it generally achieved good results compared to other methods. However, several studies documented deviations between measured and calculated reference evapotranspiration depending on local environmental conditions. Consequently, it seems advisable to evaluate the model under local environmental conditions. Evapotranspiration was determined at a subhumid site in Austria (48°12'N, 16°34'E; 157 m asl) using a large weighing lysimeter operated at (limited) reference conditions and compared with calculations according to ASCE-EWRI. The lysimeter had an inner diameter of 1.9 m and a hemispherical bottom with a maximum depth of 2.5 m. Seepage water was measured at a free draining outlet using a tipping bucket. Lysimeter mass changes were sensed by a weighing facility with an accuracy of ±0.1 mm. Both rainfall and evapotranspiration were determined directly from lysimeter data using a simple water balance equation. Meteorological data for the ASCE-EWRI model were obtained from a weather station of the Central Institute for Meteorology and Geodynamics, Austria (ZAMG). The study period was from 2005 to 2010, analyses were based upon daily time steps. Daily calculated reference evapotranspiration was generally overestimated at small values, whereas it was rather underestimated when evapotranspiration was large, which is supported also by other studies. In the given case, advection of sensible heat proved

    isotopic compositon of 14 sulfides as galena, sphalerite, pyrite and native sulfure were determined as well, with values ranging between -17.5 and 2.8 ‰ (CDT). For the investigated sulfates, the sulfur isotopic values show generally low values, which are characteristic for the late Permian. The broad distribution of sulfide values point toward bacterial reduction, fact also reflected by some higher isotopic values of sulfates. The oxygen values show a larger scatter from 9 to 23‰, which is even larger than that found for the Zechstein anhydrites of northern Germany, north-eastern Italian Alps or western Poland. The associated carbonates, as calcite, dolomite and magnesite are in disequilibrium with the sulfates indicating rather primary marine isotopic signature than re-equlibration with the sulfates at higher temperatures.

    The regional weather forecast model ALADIN of the Central Institute for Meteorology and Geodynamics (ZAMG) is used in combination with the chemical transport model CAMx (www.camx.com) to conduct forecasts of gaseous and particulate air pollution over Europe. The forecasts which are done in cooperation with the University of Natural Resources and Applied Life Sciences in Vienna (BOKU) are supported by the regional governments since 2005 with the main interest on the prediction of tropospheric ozone. The daily ozone forecasts are evaluated for the summer 2008 with the observations of about 150 air quality stations in Austria. In 2008 the emission-model SMOKE was integrated into the modelling system to calculate the biogenic emissions. The anthropogenic emissions are based on the newest EMEP data set as well as on regional inventories for the core domain. The performance of SMOKE is shown for a summer period in 2007. In the frame of the COST-action 728 „Enhancing mesoscale meteorological modelling capabilities for air pollution and dispersion applications", multi-model ensembles are used to conduct an international model evaluation. The model calculations of meteorological- and concentration fields are compared to measurements on the ensemble platform at the Joint Research Centre (JRC) in Ispra. The results for 2 episodes in 2006 show the performance of the different models as well as of the model ensemble.

    Atmospheric concentrations of many elements have been significantly increased by human activities. The quantification of these changes and their effect on the terrestrial and aquatic ecosystems is important because of their potentially adverse effects. The human nuclear activities, especially releases from the spent nuclear fuel reprocessing plants, are presently the main source of 129I in the environment. In this work, the concentration of 129I and the ratios of 129I/ 127I in aerosols weekly collected in Vienna, Austria (202 m a.s.l) during the year 2001 are presented. Iodine was extracted from the aerosol filters using a strong basic solution and separated from the matrix elements by anion exchange. The chemical yield of the procedure, determined by ICP-MS, ranges from 70% to 95%. The AMS results indicated that the 129I/ 127I isotopic ratios were of the order 10 -8 to 10 -7. The 129I originated from gaseous emissions from the Sellafield reprocessing plant. The measured 129I concentrations were compared with those of 7Be, a cosmogenic radionuclide. Although, both radionuclides exhibit nearly the same distribution pattern (higher levels in summer and lower in winter) their different origins can clearly be deduced from short term variations.

    One of the central purposes of cross-cultural psychiatry is to scrutinize the sociocultural influences on the phenomenology of psychiatric diseases. On the other hand it is possible to lay bare a nucleus of symptoms, common to all cultures, which, independently of all influences, occupies a central position for an understanding of the disease considered. In this study an attempt was made to approach this problem by means of investigating the contents of delusion of schizophrenic patients in Austria and Pakistan. The contents of delusion among 126 Austrian and 108 Pakistani patients diagnosed as having schizophrenia according to DSM-III-R (art. 295) were compared following the classification of Huber and Gross. Additionally the kind of persecution and the type of the persecutor were registered. However it appeared that only a few contents of delusion are frequent in both countries. In both countries persecution was the most frequently mentioned content of delusion. The comparison of the contents of delusion revealed significantly higher frequencies of delusions of grandeur, guilt and religious delusions in Austrian patients. Significant differences could also be found with the kind of persecution and the persecutor's type. Cultural factors seem to have a decisive influence on shaping the contents of delusion.

    In the context of the Austrian Genome Program, a tissue bank is being established (Genome Austria Tissue Bank, GATiB) which is based on a collection of diseased and corresponding normal tissues representing a great variety of diseases at their natural frequency of occurrence from a non-selected Central European population of more than 700,000 patients. Major emphasis is put on annotation of archival tissue with comprehensive clinical data, including follow-up data. A specific IT infrastructure supports sample annotation, tracking of sample usage as well as sample and data storage. Innovative data protection tools were developed which prevent sample donor re-identification, particularly if detailed medical and genetic data are combined. For quality control of old archival tissues, new techniques were established to check RNA quality and antigen stability. Since 2003, GATiB has changed from a population-based tissue bank to a disease-focused biobank comprising major cancers such as colon, breast, liver, as well as metabolic liver diseases and organs affected by the metabolic syndrome. Prospectively collected tissues are associated with blood samples and detailed data on the sample donor's disease, lifestyle and environmental exposure, following standard operating procedures. Major emphasis is also placed on ethical, legal and social issues (ELSI) related to biobanks. A specific research project and an international advisory board ensure the proper embedding of GATiB in society and facilitate international networking. PMID:17709968

    Large part of the border region between Republic of Slovenia and Republic of Austria is represented by high east west extended mountainous ridge of Karavanke/Karawanken. It is a range extending along the Slovenian-Austrian border for almost 150 km. Its terrain consists of long and prominent ridges, whose slopes steeply fall to the northern and southern side. Ridges are interrupted by long, deep and narrow valleys. The highest peaks reach over 2000 m above sea level. In the entire range prominent ridges with mountain meadows and forests prevail. The area is scarcely populated, the main economic activities are grazing and forestry, in some places tourism is also developing, especially winter sports centres. Karavanke/Karawanken lies on the contact between two continental plates, the large European plate in the north and the smaller Adriatic plate in the south. When the Adriatic plate was thrusted over the European one towards the north, the collision resulted in the folding of sediments previously deposited in the space between the plates. The contact of both plates caused large lateral displacements, causing the rocks of both plates to fold and fault and then extend along the contact. This is the area of Periadriatic lineament, dividing Karavanke/Karawanken range into their north and south part. Periadriatic lineament is large stripe slip tectonic structure along which on the northern side rocks were extruded to the east and on the southern side to the west. Along the lineament metamorphic (e.g. biotitic and feldsparic para-gneis, amfibolites) and magmatic (e.g. diabaz, granite and tonalite) rocks of various ages are present. Palaeozoic sedimentary rocks cover large part of the mountain ridge. The oldest are Silurian and Ordovician limestone on the northern border followed by Devonian ridge limestones. They are covered by molasse sedimentation in Carbon and shallow marine and river predominantly clastic sedimentation in Perm. The most abundant and with numerous

The gamma-log curve supports the biostratigraphic data very well. The gamma response becomes gradually weaker in the upper, undisturbed part of the section (Nu10-Nu0, Berriasian). The lower part (Nu18-Nu10, Tithonian) of the section shows the highest gamma responses. The gamma curve pattern at Nutzhof therefore shows decreasing values what corresponds well with decreasing values of susceptibility as well with the contrastingly, increasing values in carbonate content (from 50 per cent up to 95 per cent CaCo3) and increasing grey scale values (up to 250). The above reported results strongly suggest that the section mirrors a change of the depositional position of the Nutzhof section from a shallower into a deeper region, and a more stable environment on the European Helvetic shelf to slope during the Late Jurassic to Early Cretaceous time.

    We mostly deal here with socio-medical aspects of vaccinations. Various initiatives are summed up that are intended to optimize the system of immunization by vaccines and to establish certain innovative, and also internationally remarkable approaches. In spite of the undoubted successes of vaccinations in Austria, there still are some major deficits that should be eliminated. The Austrian system of immunization by vaccines has been mainly concentrating on continuously adapting its vaccination schedules. Such modifications are based on current scientific knowledge and thus dynamic in nature whereas the public health system necessarily relies on commonly established and easily adoptable requirements. This discrepancy has brought about a certain degree of uncertainty in some instances.--(See K. Spork, I. Mutz: "Recommendations for Vaccination in Childhood and for Adults".) By further developing immunization programs into a general concept of immunization by vaccines we should be able to put the potential benefits of preventive medical care better into effect than before because such a concept based on clearly defined public health objectives provides strategic and tactical measures and, what is even more important, also includes evaluation.--(See Vutuc, Kunze: "Epidemiology as Background for Vaccinations".) In this connection it has also been necessary to develop various activities in the field of social marketing, examples of which will be mentioned in this issue. There is mainly one recurring source of dispute that must be discussed here, the question of what is immunization of the public at large and what is immunization to be recommended for certain groups (so called risk groups). It has to be principally noted that the idea of risk group immunization has not been too effective in many areas. A typical example for such a project that has to be reconsidered is the active immunization against Central European Encephalitis (CEE) or Tick Bone Encephalitis (TBE

There is evidence from ancient genetic data for a high frequency of Y-chromosomal haplogroup G in prehistoric populations of Central Europe, whilst nowadays levels well below 10% are routinely observed. A population sample comprising ∼3700 specimens was analyzed for Y-chromosomal variation by genotyping Y-SNPs and Y-STRs. The set of binary markers included nine SNPs specific for sub-lineages of haplogroup G. The frequency of haplogroup G in 2379 unrelated men born in Tyrol amounted to 11.3%. Nearly all of these Y chromosomes belonged to haplogroup G2a. The main sub-haplogroup within G2a was defined by the SNP L497 (G2a3b1c) and reached a population frequency of 8.6%. Although this average level is higher than reported for other countries the geographical distribution of haplogroup G-L497 showed a differentiated pattern with a clustered distribution within some alpine valleys, where maxima above 40% were found. Both, the estimation of coalescent times and a principle coordinates analysis based on RST values derived from Y-STR haplotypes from different sub-regions of Tyrol revealed evidence for an old settlement history associated with Y chromosomes belonging to haplogroup G in the Tyrolean Alps.

  5. Assessing management effects on Oak forests in Austria

    Historic land use as well as silvicultural management practices have changed the structures and species composition of central European forests. Such changes have effects on the growth of forests and contribute to global warming. As insufficient information on historic forest management is available it is hard to explain the effect of management on forests growth and its possible consequences to the environment. In this situation, the BIOME-BGC model, which integrates the main physical, biological and physiological processes based on current understanding of ecophysiology is an option for assessing the management effects through tracking the cycling of energy, water, carbon and nutrients within a given ecosystems. Such models are increasingly employed to simulate current and future forest dynamics. This study first compares observed standing tree volume, carbon and nitrogen content in soil in the high forests and coppice with standards stands of Oak forests in Austria. Biome BGC is then used to assess the effects of management on forest growth and to explain the differences with measured parameters. Close positive correlations and unbiased results and statistically insignificant differences between predicted and observed volumes indicates the application of the model as a diagnostic tool to assess management effects in oak forests. The observed data in 2006 and 2009 was further compared with the results of respective model runs. Further analysis on simulated data shows that thinning leads to an increase in growth efficiency (GE), nitrogen use efficiency (NUE) and water use efficiency (WUE), and to a decrease in the radiation use efficiency (RUE) in both forests. Among all studied growth parameters, only the difference in the NUE was statistically significant. This indicates that the difference in the yield of forests is mainly governed by the NUE difference in stands due to thinning. The coppice with standards system produces an equal amount of net primary

    SummaryThis article evaluates the spatial and temporal changes in streamflow flashiness in 122 mountain catchments in Slovakia and Austria. The flashiness is quantified by the Richards-Baker flashiness index ( FI), which is the ratio of absolute day-to-day fluctuations of streamflow relative to total flow in a year. The analysis is based on daily streamflow data from the period 1976 to 2005. The results show that the average day-to-day fluctuations of streamflow vary from 6% to 43%, depending on the catchment. The spatial pattern of the FI reflects the variations in the main geological units and generally shows a trend of decreasing flashiness with increasing size of the catchment. Statistically significant temporal trends in flashiness are found in 7 Slovak and 22 Austrian catchments. Most of these trends are related to anthropogenic effects, while, in a few catchments, the change in annual flashiness appears to be caused by changes in precipitation seasonality. A multivariate statistical analysis of FI indicates negative correlations with catchment area, mean catchment elevation, percents of forest cover, agricultural land and Quaternary geology. Positive correlations are found between FI and Tertiary and Calcareous geologies. Extrapolating the regression models beyond the observed range of catchment attributes used in the estimation leads to significant prediction errors. In order to better interpret the FI values, a statistically significant relationship was found between the FI and the frequency of peak flows exceeding the long-term mean as well as between the FI and the 5% quantile of daily streamflow.

    Osteoporosis-related hip fractures represent a substantial cause of mortality and morbidity in industrialized countries like Austria. Identification of groups at high risk for mortality after hip fracture is crucial for health policy decisions. To determine in-hospital, long-term, and excess mortality after osteoporosis-related hip fracture in Austrian patients, we conducted a retrospective cohort analysis of pseudonymized invoice data from Austrian social insurance authorities covering roughly 98 % of the entire population. The data set included 31,668 subjects aged 50 years and above sustaining a hip fracture between July 2008 and December 2010 with follow-up until June 2011, and an age-, gender-, and regionally matched control population without hip fractures (56,320 subjects). Kaplan-Meier and Cox hazard regression analyses served to determine unadjusted and adjusted mortality rates: Unadjusted all-cause 1-year mortality amounted to 20.2 % (95 % CI: 19.7-20.7 %). Males had significantly higher long-term, in-hospital, and excess mortality rates than females, but younger males exhibited lower excess mortality than their female counterparts. Advanced age correlated with increased long-term and in-hospital mortality, but lower excess mortality. Excess mortality, particularly in males, was highest in the first 6 months after hip fracture, but remained statistically significantly elevated throughout the observation period of 3 years. Longer hospital stay per fracture was correlated with mortality reduction in older patients and in patients with more subsequent fractures. In conclusion, more efforts are needed to identify causes and effectively prevent excess mortality especially in male osteoporosis patients. PMID:24989776

    A foodborne norovirus outbreak occurred after a pre-Christmas celebration among a group of local foresters in Austria in December 2007. A total of 66 persons, 60 participants of the Christmas party and 6 kitchen staff members of the restaurant where the party took place, were identified as the at-risk cohort. Questioning of this cohort was performed by self-report questionnaires or telephone interviews (response rate of 95%). The outbreak attack rate was 33.3% (21 of 63 persons), including two of the kitchen staff. Three stool specimens yielded norovirus genogroup II. Univariate analysis revealed that exposure to a ham roll and pastry was possibly associated with risk of gastroenteritis (risk ratio [RR] of 4.45, 95% CI of 1.91 to 10. RR of 2.44, 95% CI of 0.93 to 6.39). After controlling for the effects of sex, age, and other food items with a log-linear model, ham roll remained significantly associated with disease risk (RR of 3.91, 95% CI of 1.57 to 9.76). Ham roll was most likely contaminated with norovirus during preparation by a disease-free kitchen assistant, whose infant became sick with laboratory-confirmed norovirus gastroenteritis 2 days before the party. Informing food handlers about the possible risk of food contamination with norovirus and training them in the appropriate measures of hand hygiene and environmental disinfection at the working place and at home are essential for preventing food-related norovirus outbreaks. Norovirus-infected household members of healthy food handlers must be considered a possible reservoir for foodborne norovirus outbreaks.

  9. Subnational responsibilities for healthcare and Austria's rejection of the EU's patients' rights directive.

    Kostera, Thomas

    2013-07-01

    In 2011, Member States and the European Parliament brought into force a Directive on the application of patients' rights in cross-border healthcare within the EU. Austria voted against this directive even though its national legislation was already in line with the rulings of the European Court of Justice which had triggered the negotiations on the directive. Why then, in the absence of any legal constraints on adapting to it, did Austria vote against the directive? The article argues that it was the federal structure of financing hospital infrastructure and the subnational level's influence on national position building which led to the rejection of the directive. The article retraces the process of position building by analyzing the interaction between the national and the subnational levels and concludes that Austria's position mirrors the national struggle between both levels of government over control of the hospital sector.

    In the recent past, significant rockfalls, which pose a danger to persons, railways and roads, occurred in the quarry of Spitz (NÖ-Austria). An existing seismic warning system did not fulfill the expected efficiency and reliability standards since the ratio of well-detected events to undetected events or false alarms was not satisfactory. Our aim was to analyze how a seismic warning system must be designed in order to overcome these deficiencies. A small-scale seismic network was deployed in the Spitz quarry to evaluate the possibility of improving the early-warning rockfall monitoring network by means of seismic observations. A new methodology based on seismic methods, which enables the detection and location of rockfalls above a critical size, was developed. In order to perform this task, a small-scale (200x200 m2) passive seismic network comprised of 7 monitoring seismic stations acquiring data in continuous mode was established in the quarry of Spitz so that it covered the rockfall hazard area. On the 2nd of October 2015, an induced rockfall experiment was performed. It began at 09:00 a.m (local time, 07:00 UTC) and lasted about 1.5 hours. The entire data set was analyzed using the pSysmon software. In order to locate the impact point of the rock falls, we used a procedure based on the back-projection of the maximum resultant amplitude recorded at each station of the network within a time window to every grid-point covering the whole area of interest. In order to verify the performance of the employed algorithm for detection and localization, we performed man-induced rock falls. We also used a terrestrial laser scanner and a camera, not only to draw the rockfall block trajectories, but also to determine the volume of rock lost or gained in the different areas of the quarry. This allowed us to relate the lost mass with the strength of the collision (Pseudo-magnitude) of the rockfall, and draw and rebuild their associated trajectory. The location test performed

    The Spannagel cave is located around 2,500 m asl at the end of the Tux Valley in Tyrol (Austria) close to the Hintertux glacier. While the area above the cave is ice free at present, it was covered by ice during past glacials as well as during colder periods of Interglacials. Presently, the temperature inside the cave is between 1.8° and 2.0° C. We used the d18O time-series of three stalagmites which grew in small distance from each other. This speleothem record is not influenced by effects of kinetic isotope fractionation due to the low temperatures in the cave. The stalagmites were precisely dated with the U/Th-method. The combined record (COMNISPA, Vollweiler et al. 2006) shows substantial variability within the last 9 kyr with features like the Holocene Climatic Optimum between 7.5 and 6.5 kyr, the Mediaeval Warm Period between 1.2 and 0.7 kyr and the Roman Warm Period between 2.25 and 1.7 kyr. In contrast, periods of lower temperatures are visible between 7.9 and 7.5, 5.9 and 5.1, 3.5 and 3 kyr, and during the LIA between 600 and 150 yr. The period between 5.9 and 5.1 kyr has equivalence in many records from various regions in both hemispheres corresponding to global cooling. It also includes the time of the Alpine Iceman at 5.3 kyr. The timing of the climatic variations revealed by COMNISPA agrees approximately with that shown by other Alpine archives. Joerin et al. (2006) dated wood and peat samples which were released by melting Swiss Alpine glaciers located between Engadin and Valais. Both the d18O maxima and minima recorded in COMNISPA clearly have counterparts in the glacier recession record. Comparisons of COMNISPA with other archives have shown that our stalagmite curve does not only record local climate but also the history of European climate. The extremely high correlation to the Hematite Stained Grain record of Bond et al. (2001) suggests that COMNISPA is a good archive for climate in the North Atlantic region (Mangini et al. 2007).

    Geomorphological inventories are being made in the State of Vorarlberg (Austria) since the mid-1950s by the University of Amsterdam. Starting as an academic training fieldwork for undergraduate geomorphology students, PhD students and staff members soon recognized the research potential of the unique alpine landscape. In particular, landforms and deposits of the ice-marginal environment and pollen records preserved in peat provide valuable proxies for climate reconstruction and give detailed insight in the former growth and decay of the Rhine glacier network and of local glaciers, and assist in reconstructing landscape development in general. A project was started in 2007 to prepare community wide inventory maps of potential geoconservation areas, based on digital geomorphological mapping in a Geographical Information System (GIS). A stepwise protocol was designed for the identification of potential geoconservation areas in the landscape, comprising: 1. Preparing digital geomorphological maps, using a morphogenetic classification scheme 2. Assigning values for selected geoconservation assessment criteria to types of geomorphological features 3. Ranking the criteria assessment values into three categories of potential geoconservation value, and 4. Storing, visualizing and describing the geoconservation data. Four major traits are used in the weighting and ranking protocol (steps 2 and 3): scientific relevance, frequency of occurrence, disturbance, and environmental vulnerability. The process of assigning values and of ranking the landforms and deposits has been automated in GIS. For the evaluation of disturbance we use digital infrastructure layers in GIS which can be intersected with the potential geoconservation areas to determine the level of disturbance. The proposed method is demonstrated for the municipality of Lech, a well-known winter skiing resort. To illustrate the loss of high-rank potential geoconservation areas due to human influence over the last 50

  14. Susceptibility to mountain hazards in Austria - paradigms of vulnerability revisited

    NASA Astrophysics Data System (ADS)

    Fuchs, Sven

    2010-05-01

    The concept of vulnerability is pillared by multiple disciplinary theories underpinning either a technical or a social origin of the concept and resulting in a range of paradigms for either a qualitative or quantitative assessment of vulnerability. However, efforts to reduce susceptibility to hazards and to create disaster-resilient communities require intersections among these theories, since human activity cannot be seen independently from the environmental setting. Acknowledging different roots of disciplinary paradigms, issues determining structural, economic, institutional and social vulnerability are discussed with respect to mountain hazards in Austria. The underlying idea of taking such an integrative viewpoint was the cognition that human action in mountain environments affects the state of vulnerability, and the state of vulnerability in turn shapes the possibilities of human action. It is argued that structural vulnerability as originator results in considerable economic vulnerability, generated by the institutional settings of dealing with natural hazards and shaped by the overall societal framework. Hence, the vulnerability of a specific location and within a considered point of time is triggered by the hazardous event and the related physical susceptibility of structures, such as buildings located on a torrent fan. Depending on the specific institutional settings, economic vulnerability of individuals or of the society results, above all with respect to imperfect loss compensation mechanisms in the areas under investigation. While this potential for harm can be addressed as social vulnerability, the concept of institutional vulnerability has been developed with respect to the overall political settings of governmental risk management. As a result, the concept of vulnerability, as being used in natural sciences, can be extended by integration of possible reasons why such physical susceptibility of structures exists, and by integration of compensation

    Human infections with tick-borne encephalitis (TBE)virus are a public health concern in certain regions of Europe, central and eastern Asia. Expansions of endemic areas and increased incidences have been associated with different factors including ecological changes supporting tick reproduction, socioeconomic changes increasing human outdoor activities and climatic changes favouring virus circulation in natural foci. Austria is among the most strongly affected countries in Central Europe, but the annual number of cases has strongly declined due to vaccination. Here,we have analysed changes of the incidence of TBE in the unvaccinated population of all federal states of Austria over a period of 42 years. The overall incidence in Austria has remained constant, but new strongly affected endemic regions have emerged in alpine valleys in the west of Austria. In parallel, the incidence in low-land regions in the north-east of the country is decreasing. There is no evidence for a shift to higher altitudes of infection sites in the traditional TBE zones,but the average altitudes of some newly established endemic areas in the west are significantly higher. Our analyses underscore the focal nature of TBE endemic areas and the potential of TBE virus to emerge in previously unaffected regions.

    The regional weather forecast model ALADIN-Austria of the Central Institute for Meteorology and Geodynamics (ZAMG) is used in combination with the chemical transport model CAMx (www.camx.com) to conduct forecasts of gaseous and particulate air pollutants over Austria. The forecasts "which are done in cooperation with the University of Natural Resources and Applied Life Sciences in Vienna (BOKU)" are supported by the regional governments since 2005. In the operational model version, the Air Quality model for Austria (AQA), uses the operational meteorological forecasts conducted with ALADIN which has a horizontal resolution of 9.7 km. Since 2008 the higher resolved ALARO is also available at the ZAMG. It has a horizontal resolution of 4.9 km and models the PBL with more vertical layers than ALADIN. ALARO also uses more complex algorithms to calculate precipitation, radiation and TKE. Another advantage of ALARO concerning the chemical modeling with CAMx is that additionally to the higher resolved meteorological forecasts it is possible to use finer emission inventories which are available for Austria. From 2006 to 2007 a SODAR-RASS of the ZAMG was operated in the north-eastern Austrian flat lands (Kittsee) which provides a comprehensive data set to compare vertical profiles of wind and temperature with the model predictions. Both models are used as meteorological driver for the chemical dispersion model CAMx. The results of predicted PM10 concentrations are compared to air quality measurements in Kittsee and also to observations in complex terrain for a selected episode.

    BACKGROUND Disaffiliation from religion is an important factor behind the rapid rise in persons claiming no religious affiliation in many advanced industrial countries. Scholars typically think of disaffiliation as a life course process that is confined to young adults, with little change occurring among older adults, yet few studies have examined this assumption outside the United States and Great Britain. OBJECTIVE We evaluate whether the young-adult model of disaffiliation from religion applies in Ireland and Austria, two historically Catholic-majority countries with different levels of non-affiliation growth. METHODS We use census data on religious affiliation in Ireland (1971–2011) and Austria (1971–2001) to track aggregate changes in the percentage reporting no religious affiliation over the life course for successive birth cohorts. RESULTS We find support for the young-adult model in Ireland. However, recent cohorts in Austria exhibit a distinct pattern of disaffiliation that continues into middle adulthood. Our analysis suggests that mid-life disaffiliation in Austria is connected to a religious tax, which we argue spurs nominally affiliated adults to disaffiliate themselves, as their income rises and the costs of religious affiliation increase. CONCLUSION Our findings offer insight into some of the social factors behind recent religious change across Europe and highlight the need for more cross-national research on the age and cohort dimensions of this change.

    The Air-Quality model for Austria (AQA) is operated at ZAMG in cooperation with the University of Natural Resources and Life Sciences (BOKU) in Vienna by order of the regional governments since 2005. The modeling system is currently a combination of the meteorological model ALARO and the photochemical dispersion model CAMx. Two modeling domains are used with the highest resolution (5 km) in the alpine region. Various extensions with external data sources have been conducted in the past to improve the daily forecasts of the model. Since 2013 O3- and PM10-observations from the Austrian measurement network have been assimilated daily using optimum interpolation. Dynamic chemical boundary conditions are obtained from Air-Quality forecasts provided by ECMWF in the frame of MACC-II. Additionally the latest available high resolved emission inventories for Austria are combined with TNO and EMEP data. The biogenic emissions are provided by the SMOKE model. ZAMG provides daily forecasts of O3, PM10 and NO2 to the regional governments of Austria. The evaluation of these forecasts is done for the summer 2013 with the main focus on the forecasts of ozone. The measurements of the Air-Quality stations are compared with the punctual forecasts at the sites of the station and with the area forecasts for every province of Austria. In the summer of 2013, two heat waves occurred. The first very short heat wave was in June 2013. During this period one exceedance of the alert threshold value for ozone occurred. The second heat wave took place from the end of July to the mid of August. Due to very high temperatures (new temperature record for Austria measured in Bad Deutsch-Altenburg with 40.5°C) and long dryness episodes the information threshold value has been exceeded several times in the eastern regions of Austria. The alert threshold value has been exceeded one time in this period. For the evaluation, the results for the second heat wave episode in Eastern Austria will be discussed

    This paper reports on the Austrian research project “Renewable energy in Austria: Modeling possible development trends until 2020”. The project investigated possible economic and ecological effects of a substantially increased use of renewable energy sources in Austria. Together with stakeholders and experts, three different scenarios were defined, specifying possible development trends for renewable energy in Austria. The scenarios were simulated for the period 2006–2020, using the integrated environment–energy–economy model “e3.at”. The modeling results indicate that increasing the share of renewable energy sources in total energy use is an important but insufficient step towards achieving a sustainable energy system in Austria. A substantial increase in energy efficiency and a reduction of residential energy consumption also form important cornerstones of a sustainable energy policy. PMID:21976785

    Promoting mental health is a central public health issue since the Jakarta statement in 1997. In Austria, the nationwide organisation for health promotion is the 'Fonds Gesundes Österreich' (FGÖ), which has been established in 1998. The FGÖ funds and supports workplace health promotion projects; therefore, it co-operates with the Austrian Network on Workplace Health Promotion. In 2011, among others, two Austrian companies were honoured as best practice models for promoting mental health in the project 'Work. In tune with life. Move Europe'. One of their central key success factors are the provision of equal opportunities, engagement, their focus on overall health as well as the implementation of behavioural and environmental preventive measures. Since mental health problems in the population are still rising, public health promotion projects which orientate on the best practice models have to be established in Austria. PMID:24327008

    The asteroids 136 Austria and 238 Hypatia were observed photoelectrically in UBV during four nights in Feb. 1981, using the 0.6 m Bochum telescope (ESO-time) at the European Southern Observatory, La Silla, Chile. For 136 Austria, a rotation period of P equals 11.5 + or 0.1 h (0.479 + or - 0.004 d) could be derived with a lightcurve partially observed and an amplitude of at least 0.40 mag. 238 Hypatia has a rotation period of P equals 8.9 + or - 0.1 h (0.371 + or - 0.004 d) and a lightcurve amplitude of 0.12 mag. For both asteroids UBV-colors were measured frequently and no variation during rotation was remarked, exceeding the scatter.

    A total of 341 clinical isolates of Streptococcus pyogenes from Vienna, Austria and three Hungarian cities were tested for susceptibility to four macrolides and 12 other antibiotics. All isolates were fully susceptible to penicillin and the other beta-lactams tested. A high level of tetracycline resistance was found in Austria (26.7%) and in Hungary (30.5%). The rate of resistance to erythromycin, clarithromycin and azithromycin was 4.7% in Vienna and 3.7% in the Hungarian communities. In both countries, the MIC(90) values of erythromycin and clarithromycin were 0.12 mg/L and the MIC(90) of josamycin was 0.5mg/L. The M phenotype of resistance conferred by the mefA genes was predominant (n = 9) among the macrolide-resistant isolates (n = 14).

    GIN AUSTRIA (Gesundheitsinformationsnetz AUSTRIA) offers patients and consumers reliable medical knowledge about diseases, wellness and disease management in an understandable way and enables them to quick and incessant access to informations about the Austrian health system and Austrian health organizations. To improve the quality of the database and to achieve full customer (patients, citizens) satisfaction a systematic approach for implementing total quality management is also applied. Focusing the attention on understanding and responding to customer needs, systematic and continuous improving of the IS and total involvement of all participants are the three core TQM principles at this project. The second focus of the project is the development and the implementation (prototype) of a medical dictionary or rather medical thesaurus as interface for patients, who are not used to scientific terms and expressions. This interface is based on the controlled vocabulary of the MeSH-Thesaurus (german version).

    The effect of the moon on the number of newborns has been investigated extensively with contradictory results but with few significant findings. In this paper, a possible lunar effect is analyzed by a nonlinear Poisson regression model similar to a Fourier analysis based on all children (n = 2,760,362) born in Austria between 1970 and 1999, i.e. 371 lunar cycles. We found no significant effect even when considering the influence of parity and gestation. Our study is in contrast to a French study using a similarly large data base which showed a weak but significant effect. Nevertheless, significant p values based on very large samples must be interpreted cautiously. Our study is in concordance with other studies which often use small and selected samples or rather inefficient statistical methods. We conclude that there is no significant effect of the lunar cycle on the number of deliveries in Austria.

    On the basis of several carapaces, a new species of xanthid crab, Etisus evamuellerae, is described from the Middle Miocene of the Vienna (Austria) and Great Hungarian basins. It differs from the coeval xanthids, Xantho moldavicus and Pilodius vulgaris, in having a distinctly protruding front and comparatively longer carapace. Contrary to those two species, the new one makes up for just a small percentage in the decapod crustacean assemblages studied. PMID:25983383

    Since its inception in 2010, the Arab Spring has evolved into a situation of violent conflict in many countries, leading to high levels of migration from the affected region. Given the social impact of the large number of individuals applying for asylum across Europe in 2015, it is important to study who these persons are in terms of their skills, motivations, and intentions. DiPAS (Displaced Persons in Austria Survey) aims to uncover the socio-demographic characteristics of the persons seeking refuge who arrived in Austria in 2015, mainly originating from Syria, Iraq and Afghanistan. Particular focus is on human capital, attitudes and values. This survey, the first of its kind in Austria and possibly in Europe, was carried out among adult displaced persons, mostly residing in Vienna, yielding 514 completed interviews. Information gathered on spouses and children allows for the analysis of 972 persons living in Austria, and of further 419 partners and children abroad. Results indicate that the surveyed population comprised mainly young families with children, particularly those coming from Syria and Iraq. Their educational level is high compared with the average level in their country of origin. A vast majority of respondents are Muslims, rating their religiosity at medium levels. Judging from stated attitudes towards gender equity, interviewed men seem to have more liberal attitudes than their compatriots. The majority of respondents do not intend to return to their home countries, mostly because of the perception of permanent threat. DiPAS provides data for political decision-making and the on-going societal dialogue. Its findings can help to inform assessments about the integration potential of the displaced population into the host society. In addition, the applied methodological technique and experiences during the fieldwork provide valuable insights on sampling asylum seekers and refugees in the current European context.

    With the bluetongue virus serotype 8 (BTV-8) outbreak in 2006, vector monitoring programmes (according to EU regulation 1266/2007) were implemented by European countries to obtain information on the spatial distribution of vectors and the vector-free period. This study investigates the vector monitoring programmes in Austria and Switzerland by performing a retrospective cost analysis for the period 2006-2010. Two types of costs were distinguished: costs financed directly via the national bluetongue programmes and costs contributed in-kind by the responsible institutions and agricultural holdings. The total net costs of the monitoring programme in Austria amounted to €1,415,000, whereby in Switzerland the costs were valued at €94,000. Both countries followed the legislation complying with requirements, but differed in regard to sampling frequency, number of trap sites and sampling strategy. Furthermore, the surface area of Austria is twice the area of Switzerland although the number of ruminants is almost the same in both countries. Thus, for comparison, the costs were normalised with regard to the sampling frequency and the number of trap sites. Resulting costs per trap sample comprised €164 for Austria and €48 for Switzerland. In both countries, around 50 per cent of the total costs can be attributed to payments in-kind. The benefit of this study is twofold: first, veterinary authorities may use the results to improve the economic efficiency of future vector monitoring programmes. Second, the analysis of the payment in-kind contribution is of great importance to public authorities as it makes the available resources visible and demonstrates how they have been used.

    Borrelia bavariensis was recently described as a distinct genospecies among the B. burgdorferi sensu lato complex. The prevalence of B. bavariensis in Austria, a highly endemic area for tick-transmitted pathogens, is scarcely characterized. To investigate the prevalence of B. bavariensis in Ixodes ricinus ticks we reevaluated the results of a study conducted in 518 ticks from southeastern Austria collected in 2002 and 2003. The presence of B. burgdorferi s.l.-specific DNA in ticks was analyzed by a PCR for the outer surface protein A (ospA) gene. Borrelia species were differentiated by restriction fragment length polymorphism (RFLP) analysis, and samples positive for B. bavariensis were further analyzed by multilocus sequence analysis. Two of 133 (1.5%) B. burgdorferi s.l.-positive I. ricinus ticks were infected with B. bavariensis. Both specimens were coinfected with the OspA serotype 5 of B. garinii. Borrelia bavariensis is present; however, seem to be rare in I. ricinus ticks in southeastern Austria.

    Long-term care for the aged is an area that has not been in the focus of health promotion so far. The paper describes context, concept and project plan of a 2-year pilot project of comprehensive health-promoting setting development in residential aged care in Austria, and provides an overview over main experiences and results. Austria's most relevant health promotion agencies, a specialized scientific institute and Austria's largest provider of aged care acted as partners. The project aimed at developing elements of a comprehensive approach, but also providing evidence for the effectiveness of health promotion. Therefore, the project combined an organizational development approach with a scientific, randomized controlled study on mobility enhancement for residents. A comprehensive settings approach turned out acceptable for the main stakeholders of aged care (owners and management, staff, residents and residents' relatives). Strategy development, based on a systematic needs assessment, found staff health to be of special interest for the organization (ergonomics, workability over life course), and residents' relatives, got more attention. The mobility study was able to achieve positive results on occupational performance, concerning quality-of-life indicators and reached also formerly inactive groups. After the end of the project, health promotion is still on the agenda of the organization; further developments will be monitored. Good support from the policy level and well-established networking between the aged care provider, health promotion agencies and a network for health promotion in health care seems to have been an important resource for success.

    The complete 1992 register of minimal invasive operations at all surgical departments in Austria has been compiled for the third year running, representing questionnaires returned from 107 departments reporting a total of 11,591 laparoscopic cholecystectomies (LC). Evaluation of the data from the 81 departments with a least 2 years' experience showed an increase of 56.60% in the number of LCs and an overall increase in cholecystectomies of 18.50% in comparison with 1991. Sonography and/or intravenous cholangiography remain the standard procedures for the pre-operative diagnosis of bile-duct concrements, undertaken in 98.05% and 71.70%, respectively, of all cases in 1992. Intra-operative cholangiography has been implemented with increasing frequency (17.56% of all cases in 1992), especially in those departments with longer experience on LC. The conversion rate to open cholecystectomy was 6.09%, and the incidence of secondary cholecystectomy was 1.26%. The mortality rate was 0.11%. Our register now contains the data on 19,872 LCs. Our evaluation of the multicentric data aims at a complete documentation of the frequency of this surgical procedure and the incidence of complications in Austria with a view to establishing guidelines for the indications for LC and planning of this operation, as well as following up current trends in the regional implementation of LC in Austria.

    Background Despite three decades of prenatal screening program for toxoplasmosis in Austria, population-based estimates for the incidence of maternal infections with Toxoplasma gondii during pregnancy are lacking. We studied the incidence of primary maternal infections during pregnancy in the Federal State of Upper Austria. Methods Screening tests for 63,416 women and over 90,000 pregnancies (more than 84.5% of pregnancies in the studied region) in the time period between 01.01.2000 and 31.12.2007 were analysed. The incidence of toxoplasmosis was estimated indirectly by binomial and directly by interval censored regression. Results During the studied period, 66 acute infections (risk of 0.07% per pregnancy) were detected, but only 29.8% of seronegative women were tested at least three times during their pregnancies. The seroprevalence of Toxoplasma antibodies among all tested women was 31%. Indirectly estimated incidence (from differences in prevalence by age) was 0.5% per pregnancy, while directly estimated incidence (interval censored regression) was 0.17% per pregnancy (95% confidence interval: 0.13-0.21%). Conclusions Calculating incidence from observed infections results in severe underreporting due to many missed tests and potential diagnostic problems. Using statistical modelling, we estimated primary toxoplasmosis to occur in 0.17% (0.13-0.21%) of all pregnancies in Upper Austria. PMID:22168604

    Approximately one-sixth of Austria’s land surface is karstified One-fourth of the precipitation falling in Austria lands in these karst areas, providing one-third of the population with drinking water If the projected future water needs of Austria are to be met, optimal utilization and protection of these karst water supplies is necessary To achieve these goals, community officials and civil engineers must understand the nature of karst water resources and the problems associated with their utilization At the recommendation fo the Federal Ministry for Agriculture and Forestry of the Republic of Austria, a pamphlet designed to provide this critical information has been written. The four major areas discussed in the pamphlet are definitions and descriptions of karst water flow and occurrence, discharge and physiochemical requirements for karst water supplies, requisite environmental studies of all possible sources of qualitative and/or quantitative damage to the karst water supply and engineering methods that can aid in preventing such damage, and legislative provisions necessary to protect karst water resources from water quality or quantity degradation In addition, the role of the public in karst water supply protection is discussed.

    In this paper, it is shown how to select the optimal wavelengths minimizing the relative error and the standard deviation of the temperature. Furthermore, it is shown that the optimal wavelengths in mono-spectral and bi-spectral methods (for a Planck's law) can be determined by laws analogous to the displacement Wien's law. The simplicity of these laws can thus allow real-time selection of optimal wavelengths for a control/optimization of industrial processes, for example. A more general methodology to obtain the optimal wavelengths selection in a multi-spectral method (taking into account the spectral variations of the global transfer function including the emissivity variations) for temperature measurement of surfaces exhibiting non-uniform emissivity, is also presented. This latter can then find an interest in glass furnaces temperature measurement with spatiotemporal non-uniformities of emissivity, the control of biomass pyrolysis, the surface temperature measurement of buildings or heating devices, for example. The goal consists of minimizing the standard deviation of the estimated temperature (optimal design experiment). For the multi-spectral method, two cases will be treated: optimal global and optimal constrained wavelengths selection (to the spectral range of the detector, for example). The estimated temperature results obtained by different models and for different number of parameters and wavelengths are compared. These different points are treated from theoretical, numerical and experimental points of view.

    Morphometry is a suitable method to describe geomorphological landform elements in different scales. Here, we present a workflow investigating the suitability of an area-wide elementary landform map computed for the entire country of Austria to delineate major natural geomorphological regions by analyzing spatial variability and distribution of elementary landforms. The workflow makes use of r.geomorphon, an extension module for the free and open source geographic information system GRASS GIS. It is a raster based tool that intends to delineate landform elements by applying a pattern recognition algorithm which is based on the visible neighborhood computed from a focal pixel. The input parameter lookup distance (L) represents the maximum distance for line-of-sight calculations for each pixel. Applying a local ternary pattern concept and a lookup table used for classification, a map containing the landform elements flat, peak, ridge, shoulder, slope, spur, hollow, footslope, valley and pit is generated. Jasciewicz and Stepinski (2013), who authored the extension, applied it to create a general geomophometric map of Poland. We present a geomorphon-based landform map of Austria calculated with r.geomorphon with L=1500 m, which corresponds to 60 pixels based on the 25 m digital elevation model (DEM) provided by the European Environmental Agency. The visual inspection of the resulting map allows the viewer to distinguish major natural geomorphologic regions of Austria. For instance, the variability and distribution of landform elements i.e. classified geomorphons within the crystalline rocks of the Bohemian massive in the northern part of Austria seem to be similar to those of the area encompassed by the Austrian Alps, however at a much finer scale. In contrast, the Vienna Basin can be clearly identified by a sudden shift in the distribution of the landform elements towards the element "flat". For an objective, transferable and reproducible approach we developed a

    Political and social issues have a major impact on how and when HIV infection and AIDS are treated, and were a major component of the meeting in Vienna. Many discussions were held on aspects such as epidemiology, risk behavior, public health, human rights, political responses to the epidemics challenge, social stigma and discrimination, use of and recommendations on the use of condoms and other preventive measures... However, the availability of drugs and/or other therapies is a crucial issue, and while it was not the main focus of attention during this year's international AIDS conference, it will be the focus of the following report. Indeed, intensive research for new antiretrovirals continues, with new active compounds presented during the poster sessions at the Wien Messe convention center, but a wide armamentarium is currently already available, including late-generation agents such as darunavir, etravirine, raltegravir and maraviroc that provide reliable effectiveness as rescue therapy for patients failing older drug-containing highly active regimens (Azkune Galparsoro, H. et al., Abst THPE0141). All information across the meeting related to therapies for HIV infection are briefly reviewed in the following report, which complements and guides through the extensive information available on the organizing society's website.

    An impressive two-third or about 40GWh/y of electricity in Austria is produced from renewable energy sources, in particular hydro energy. For the remaining part the country depends on fossil fuels, which together with iron & steel production form the most CO2 intensive industries in Austria with a combined emission of just over 20Mt/y. According to the IEA, CO2 capture and geological storage (CCS) can reduce the global CO2 emission until 2050 by 17%. A correct assessment of CCS needs to start with the storage potential. Prior to this study, only general estimates of the theoretical capacity of Austrian reservoirs were available, thus, up until now, the realistic potential for CCS technology has not been assessed. Both for policy and industry, an assessment of the matched capacity is required, which is the capacity that actually will be used in CCS projects. This hurdle can be taken by applying a recently developed methodology (Welkenhuysen et al., 2013). This policy support system (PSS) consists of two parts, PSS Explorer and PSS III simulator. In brief, the methodology is based on expert judgements of potential reservoirs. These assessments can provide the best available data, including the expert's experience and possibly confidential data, without disclosing specific data. The geo-techno-economic calculation scheme PSS Explorer uses the expert input to calculate for each individual reservoir an assessment of the practical capacity (as probability density functions), in function of an acceptable price for storage. This practical capacity can then be used by the techno-economic PSS III simulator to perform advanced source-sink matching until 2050 and thus provide the matched reservoir capacity. The analysed reservoirs are 7 active or abandoned oil and gas reservoirs in Austria. The simulation of the electricity and iron & steel sector of Austria resulted in the estimation of the geological storage potential, taking into account geological, technological and

    This is the third of a three-part paper series through which we assess the performance of runoff predictions in ungauged basins in a comparative way. Whereas the two previous papers by Parajka et al. (2013) and Salinas et al. (2013) assess the regionalisation performance of hydrographs and hydrological extremes on the basis of a comprehensive literature review of thousands of case studies around the world, in this paper we jointly assess prediction performance of a range of runoff signatures for a consistent and rich dataset. Daily runoff time series are predicted for 213 catchments in Austria by a regionalised rainfall-runoff model and by Top-kriging, a geostatistical estimation method that accounts for the river network hierarchy. From the runoff time-series, six runoff signatures are extracted: annual runoff, seasonal runoff, flow duration curves, low flows, high flows and runoff hydrographs. The predictive performance is assessed in terms of the bias, error spread and proportion of unexplained spatial variance of statistical measures of these signatures in cross-validation (blind testing) mode. Results of the comparative assessment show that, in Austria, the predictive performance increases with catchment area for both methods and for most signatures, it tends to increase with elevation for the regionalised rainfall-runoff model, while the dependence on climate characteristics is weaker. Annual and seasonal runoff can be predicted more accurately than all other signatures. The spatial variability of high flows in ungauged basins is the most difficult to estimate followed by the low flows. It also turns out that in this data-rich study in Austria, the geostatistical approach (Top-kriging) generally outperforms the regionalised rainfall-runoff model.

    Current interest into past climate change and its potential role for changes in the environment call for spatially distributed climate datasets of high temporal resolution and extending over several decades. To foster such research, we present a new gridded dataset of daily minimum and maximum temperature covering Austria at 1-km resolution and extending back till 1961 at daily time resolution. To account for the complex and highly variable thermal distributions in this high-mountain region, we adapt and employ a recently published interpolation method that estimates nonlinear temperature profiles with altitude and accounts for the non-Euclidean spatial representativity of station measurements. The spatial analysis builds upon 150 station series in and around Austria (homogenised where available), all of which extend over or were gap-filled to cover the entire study period. The restriction to (almost) complete records shall avoid long-term inconsistencies from changes in the station network. Systematic leave-one-out cross-validation reveals interpolation errors (mean absolute error) of about 1 °C. Errors are relatively larger for minimum compared to maximum temperatures, for the interior of the Alps compared to the flatland and for winter compared to summer. Visual comparisons suggest that valley-scale inversions and föhn are more realistically captured in the new compared to existing datasets. The usefulness of the presented dataset (SPARTACUS) is illustrated in preliminary analyses of long-term trends in climate impact indices. These reveal spatially variable and eventually considerable changes in the thermal climate in Austria.

    Several environmental media in Austria were monitored for artificial radionuclides released during the Fukushima nuclear accident. Air (up to 1.2 mBq/m(3) particulate (131)I) and rainwater (up to 5.2 Bq/L (131)I) proved to be the media best suited for the environmental monitoring, allowing also a temporal resolution of the activity levels. Significant regional differences in the wet deposition of (131)I with rain could be observed within the city of Vienna during the arrival of the contaminated air masses. Forward-trajectory analysis supported the hypothesis that the contaminated air masses coming from the northwest changed direction to northeast over Northern Austria, leading to a strong activity concentration gradient over Vienna. In the course of the environmental monitoring of the Fukushima releases, this phenomenon-significant differences of (131)I activity concentrations in rainwater on a narrow local scale (8.1 km)-appears to be unique. Vegetation (grass) was contaminated with (131)I and/or (137)Cs at a low level. Soil (up to 22 Bq/kg (137)Cs) was only affected by previous releases (nuclear weapon tests, Chernobyl). Here, also significant local differences can be observed due to different deposition rates during the Chernobyl accident. The effective ecological half-lives of (137)Cs in soil were calculated for four locations in Austria. They range from 7 to 30 years. No Austrian sample investigated herein exceeded the detection limit for (134)Cs; hence, the Fukushima nuclear accident did not contribute significantly to the total radiocesium inventory in Austrian environmental media. The levels of detected radioactivity were of no concern for public health.

    A single mechanism of azole resistance was shown to predominate in clinical and environmental Aspergillus fumigatus isolates from the Netherlands, and a link to the use of azoles in the environment was suggested. To explore the prevalence of azole-resistant A. fumigatus and other aspergilli in the environment in other European countries, we collected samples from the surroundings of hospitals in Copenhagen, Innsbruck, and Madrid, flowerbeds in an amusement park in Copenhagen, and compost bags purchased in Austria, Denmark, and Spain and screened for azole resistance using multidish agars with itraconazole, voriconazole, and posaconazole. EUCAST method E.DEF 9.1 was used to confirm azole resistance. The promoter and entire coding sequence of the cyp51A gene were sequenced to identify azole-resistant A. fumigatus isolates. A. fumigatus was recovered in 144 out of 185 samples (77.8%). Four A. fumigatus isolates from four Danish soil samples displayed elevated azole MICs (8%), and all harbored the same TR/L98H mutation of cyp51A. One A. lentulus isolate with voriconazole MIC of 4 mg/liter was detected in Spain. No azole-resistant aspergilli were detected in compost. Finally, A. terreus was present in seven samples from Austria. Multi-azole-resistant A. fumigatus is present in the environment in Denmark. The resistance mechanism is identical to that of environmental isolates in the Netherlands. No link to commercial compost could be detected. In Spain and Austria, only Aspergillus species with intrinsic resistance to either azoles or amphotericin B were found.

    Recently, a new mesothelioma epidemic was predicted from observations made in Western Europe. From early observations in Austria the lower increase in cases of mesothelioma compared with neighbor countries had been related to different uses of asbestos. In order to test this hypothesis, incidence and mortality of pleural cancer [International Classification of Diseases (ICD)-8/9 163] were analyzed for three decades and supplemented by data from a cohort study in the factory that had been the largest consumer of asbestos imported to Austria and from all Austrian occupational diseases registered between 1990 and 2001. In men, mortality rates (based on 15 to 45 deaths/year) were lowest in 1980-1989, but similar in 1970-1979 and 1990-2001. No increase in younger-birth cohorts was detected. Incidence rates (based on 13 to 44 cases/year) increased (36%) non-significantly ( P=0.14). In women, a significant decrease in mortality and incidence rates ( P<0.01) was observed from 1970. Rates from work-related mesothelioma (based on only 0-7 men and 0-4 women/year) must be interpreted with caution. In the cohort of 2,816 asbestos cement workers 26 pleural mesotheliomas were registered from 1990 through mid-1999. Six of these cases (three male and three female) had not been registered as an occupational disease, but all of these cases had been encoded under ICD 163 in mortality statistics. One female cohort member registered as having asbestosis according to the death certificate had died from mesothelioma according to the statistics of occupational diseases. We conclude that no epidemic of mesothelioma due to past asbestos exposure is to be expected in Austria.

    Highlights: • Informal collectors from Hungary collect bulky waste and reusable items in Austria. • Two methodologies were applied to estimate the informally collected quantities. • Both approaches lead to an estimation of roughly 100,000 t p.a. informally collected. • The formal Austrian system collects 72 kg/cap/yr of bulky waste, WEE & scrap metal. • Informal collection amounts to approx. 12 kg/cap/yr. - Abstract: Disparities in earnings between Western and Eastern European countries are the reason for a well-established informal sector actively involved in collection and transboundary shipment activities from Austria to Hungary. The preferred objects are reusable items and wastes within the categories bulky waste, WEEE and metals, intended to be sold on flea markets. Despite leading to a loss of recyclable resources for Austrian waste management, these informal activities may contribute to the extension of the lifetime of certain goods when they are reused in Hungary; nevertheless they are discussed rather controversially. The aim of this paper is to provide objective data on the quantities informally collected and transhipped. The unique activities of informal collectors required the development and implementation of a new set of methodologies. The concept of triangulation was used to verify results obtained by field visits, interviews and a traffic counting campaign. Both approaches lead to an estimation of approx. 100,000 t per year of reusable items informally collected in Austria. This means that in addition to the approx. 72 kg/cap/yr formally collected bulky waste, bulky waste wood, household scrap (excluding packaging) and WEEE, up to a further 12 kg/cap/yr might, in the case that informal collection is abandoned, end up as waste or in the second-hand sector.

  6. What's left? - Investigations on soil cover of conservation tillage methods in Austria

    One of the most accepted and a practicable method to prevent soil from erosion is conservation tillage. If conservation tillage practices are performed in a proper way soil is protected from wind and water erosion. This study deals with the effectivity of conservation tillage practices under real field conditions. Therefore we i) carried out rainfall simulation experiments employing conservation tillage practices which had been proposed by farmers to test whether actual conservation tillage practices would be effective, ii) did an observation of mean soil cover on arable land after seeding in Lower and Upper Austria for field sites where conservation tillage was funded. Rainfall simulation experiments were carried out in the years 2011 and 2012 for various conservation tillage treatments consisting of different mulching and no tillage techniques. To evaluate results on surface runoff and erosion we additionally measured soil cover, bulk densities and surface roughness of the experimental plots. Soil cover estimation of the arable land in Lower and Upper Austria which is funded for conservation tillage practices was done in 2012 and 2013. Altogether on 146 randomly chosen field sites soil cover was estimated by using an object-based image analysis method. Results reveal that the effectiveness of conservation tillage was depending on the existence of a sufficient soil cover. However, under conditions of actual farm practices, a sufficient soil cover was not obtained for mulching treatments in 2011 and only partially in 2012. Therefore, mulching treatments partially gained even higher surface runoff and soil loss rates than conventional tillage practices. Due to their high soil cover, soil loss and surface runoff of no tillage treatments were very small as compared to all other tested treatments. The results of the soil cover estimation in Lower and Upper Austria show that under practicable land use a mean soil cover of 12 percent can be reached, what's rather low in

    Since the beginning of human settlement extensive land cover and land use changes have induced significant geomorphic landscape changes as water and sediment dynamics have been transformed. The presented project focuses on the reconstruction of Holocene geomorphic landscape evolution and the assessment of recent geomorphic processes in the Northern foothills of the Eastern Alps in Austria - an area intensively agriculturally used since the middle ages and often overlooked in its geomorphic evolution. The study area is a small catchment (ca. 66 ha) which is located in the western part of Lower Austria comprising a land use history as well as environmental settings typical for wide regions across the Northern foothills of the Eastern Alps in Austria. The catchment elevation ranges from 268 to 323 m a.s.l. and has a mean slope angle of 8%. The climate in this region can be characterized as humid. The lithology mainly consists of Tertiary marly to sandy deposits which are superimposed by Quaternary sediments (e.g. loesses). Dominant soil types are Cambisols, Luvisols, and Planosols. Furthermore, the catchment is used as a Hydrological Open Air Laboratory (HOAL) implemented for the long-term research of water-related flow and transport processes in the landscape (http://hoal.hydrology.at). The main objective of this research project is to reconstruct Holocene landscape evolution by analyzing physical parameters of sediment cores taken from colluvial and alluvial sediment archives with additional 14C and OSL dating as well as by the measurement of truncated and covered standardized Luvisol profiles. First results will be presented at the EGU General Assembly 2016.

  8. Unregulated access to health-care services is associated with overutilization--lessons from Austria.

    The Austrian health-care system is characterized by free provider choice and uncontrolled access to all levels of care. Using primary data, the ECOHCARE study shows that hospitalization rates for the secondary and tertiary care levels in Austria are both 4.4 times higher than those reported from the USA using a similar methodology. At the same time, essential functions of the primary care sector are weak. We propose that regulating access to secondary and tertiary care and restricting free provider choice to the primary care level would both reverse over utilization and strengthen the primary care sector.

    This study examines the skeletal remains of a subadult from an archeological site in Austria. Radiocarbon dating and archeological attribution indicate that this individual is of pre-Columbian origin. Most of the skeleton was recovered, and only the teeth and the orbital roofs show changes. Dental defects such as the mulberry molar and a tapered, fang-like canine suggest a diagnosis of congenital syphilis. This is the first probable case of congenital syphilis from pre-Columbian Central Europe. Our findings contribute to the pre-Columbian theory, offering counter evidence to the assumption that syphilis was carried from Columbus' crew from the New to the Old World.

    Vaccination against the sexually transmitted Human Papilloma Virus (HPV), a necessary agent for the development of cervical cancer, has triggered much debate. In Austria, HPV policy turned from “lagging behind” in 2008 into “Europe's frontrunner” by 2013. Drawing on qualitative research, the article shows how the vaccine was transformed and made “good enough” over the course of five years. By means of tinkering and shifting storylines, policy officials and experts disassociated the vaccine from gender, vaccine manufacturers, and youth sexuality. Ultimately, the HPV vaccine functioned to strengthen the national immunization program. To this end, preventing an effective problematization of the extant screening program was essential.

    We assessed the prevalence of verotoxigenic Escherichia coli (VTEC) in chamois (Rupicapra rupicapra) and livestock grazing on a mountain pasture in Austria during June-August 2009. We detected VTEC throughout the sampling period in high numbers in cattle as well as in chamois, leading to the assumption that the degree of contamination of the environment is high. This is the first report of pathogenic E. coli identified in chamois, implicating chamois as a new potential reservoir of these zoonotic pathogens. Because the study area also serves recreational purposes, there is a risk of humans acquiring infection via direct or indirect contact. PMID:21719837

    Since 2002 OGS (Istituto Nazionale di Oceanografia e di Geofisica Sperimentale) in Udine (Italy), the Zentralanstalt für Meteorologie und Geodynamik (ZAMG) in Vienna (Austria), and the Agencija Republike Slovenije za Okolje (ARSO) in Ljubljana (Slovenia) are using the Antelope software suite as the main tool for collecting, analyzing, archiving and exchanging seismic data in real time, initially in the framework of the EU Interreg IIIA project "Trans-national seismological networks in the South-Eastern Alps" (Bragato et al., 2004, 2010). The data exchange has proved to be effective and very useful in case of seismic events near the borders between Italy, Austria and Slovenia, where the poor single national seismic networks coverage precluded a correct localization, while the usage of common data from the integrated networks improves considerably the overall reliability of real time seismic monitoring of the area (Fig. 1). At the moment the data exchange between the seismic data centers relies on their internet connections: this however is not an ideal condition for civil protection purposes, since the reliability of standard internet connections is poor. For this reason in 2012 the Protezione Civile della Provincia Autonoma di Bolzano in Bolzano (PCBZ, Italy), OGS, ZAMG subsidiary in Tirol (ZAMG Tirol) and ARSO joined in the Interreg IV Italia-Austria Project "SeismoSAT" (Progetto SeismoSAT, 2012) aimed in connecting the seismic data centers in real time via satellite. ARSO does not belong to the Interreg Italia-Austria region: for this reason ARSO joined the SeismoSAT project as an "associated partner", which, according to Interreg rules can not be funded. ARSO participation in the project is therefore at the beginning limited in benefiting only indirectly from improvement in the robustness of the data exchange between the other data centers, while eventually fully taking part in the project if other sources of funding will be available. The project is in a

  14. Influence of weak motion data to magnitude dependence of PGA prediction model in Austria

    Data recorded by the STS2-sensors at the Austrian Seismic Network were differentiated and used to derive the PGA prediction model for Austria (Jia and Lenhardt, 2010). Before using it to our hazard assessment and real time shakemap, it is necessary to validate this model and obtain a deep understanding about it. In this paper, influence of weak motion data to the magnitude dependence of our prediction model was studied. In addition, spatial PGA residuals between the measurements and predictions were investigated as well. There are 127 earthquakes with a magnitude between 3 and 5.4 that were used to derive the PGA prediction model published in 2011. Unfortunately, 90% of used PGA measurements were made for the events with a magnitude smaller than 4. Only ten quakes among them have a magnitude larger than 4, which is the important magnitude range that needs our attention and hazard assessment. In this investigation, 127 earthquakes were divided into two groups: the first group only includes events with a magnitude smaller than 4, while the second group contains quakes with a magnitude larger than 4. By using the same modeling for estimating PGA attenuation in 2011, coefficients of the model were inverted from the measurements in two groups and compared to the one based on the complete data set. It was found that the group with the weak quakes returned results that only have small differences to the one from all 127 events, while the group with strong quakes (ml> 4) gave greater magnitude dependence than the model published in 2011. The distance coefficients stayed nearly unchanged for all three inversions. As the second step, spatial PGA residuals between the measurements and the predictions from our model were investigated. As explained in Jia and Lenhardt (2013), there are some differences in the site amplifications between the West- and the East-Austria. For a fair comparison, residuals were normalized for each station before the investigation. Then normalized

    The essential oil compositions of the different plant parts of wild growing caraway (Carum carvi, Apiaceae) were analyzed by GC/MS and GC/FID. The plants came from two meadows in the Vienna region, Austria. The oils from young fruits had a high proportion of limonene (61-83%), and those from inflorescences limonene (39-62%) and germacrene D (23-41%). The carvone contents of fruits, inflorescences and leaves varied greatly. Leaves and stems, low in volatiles, were dominated by germacrene D and germacrene A. Therefore, wild caraway appears as a valuable aromatic herb in meadows.

    A giant termite is described and figured from the Late Miocene of the Styrian Basin in southeastern Austria. Gyatermes styriensis gen. n. et sp. n. is represented by a relatively complete forewing, with basal scale. The fossil approximates in size the largest of all termites today and is the largest fossil termite on record. The presence of this species in the Late Miocene fauna of Europe indicates that climatic conditions were appropriate for the persistence of species and colonies requiring relatively stable, warm conditions. The genus is primitive in overall features but shares some similarity with the dampwood termites.

    Knowledge about seasonal trends in acute toxoplasmosis in pregnancy may help to understand and avoid risk factors for infection. Analysing regular screening records of 51 754 pregnant women, members of the largest statutory health insurance company in the federal state of Upper Austria from 2000 to 2005, we found a twofold increase of diagnoses of acute toxoplasmosis during winter months. Taking the delay between infection and screening into account, the increased number of detections in winter points towards more frequent infections in autumn. We propose a higher consumption of contaminated vegetables and fruit from gardening as one of the potential explanations.

    In January 2013, after an intense rainfall of about 400 mm, the historic slope movement northwest of the village of Pechgraben (municipality Großraming, Upper Austria) started to move. Already in early March the landslide with an area of about 7 hectares came to a halt. After the long-lasting rainfall (200mm) from June 1st to 3rd 2013 the Pechgraben landslide was reactivated with an extent of about 80 ha on June 6th. This landslide is therefore the largest in Austria since the last 5 years. Several million cubic meters of loose material was moving towards the settlement area. Already one day later, on June 7th, 2013, emergency measures began immediately. The Geological Survey of Austria (GBA), the University of Natural Resources and Life Sciences, Institute of Mountain Risk Engineering (IAN), and the consultant engineering office Moser/Jaritz as well as the local fire brigade and the federal armed forces supported the Torrent and Avalanche Control with their remediation measures. In addition to the emergency measures, which consisted mainly of water diversion and material removal, a comprehensive monitoring system (GPS, inclinometer, geoelectric monitoring, airborne laserscan and aerial photogrammetry, etc.) has been created in order to document the development of the slope movement and to be able to take further measures if necessary. The geophysical part undertaken by the Geological Survey of Austria consisted of an airborne geophysical survey (EM, magnetics, gamma radiation) as well as several geoelectric profiles to understand the geology and mechanism of the landslide. To monitor the movement, we set up 5 different geoelectrical monitoring profiles, permanent inclinometers, photo monitoring, piezometers, as well as soil humidity and precipitation sensors.

    their application to key areas of condensed matter physics. Researchers from industry mainly focused on challenges arising from applied industrial research; contributions describing successful applications of DFT techniques to industrial problems were more scarce. Progress during the last decade has been very fast. The ESF research program has been renewed under the much bolder title 'Towards Computational Materials Design' and is now approaching the end of this second funding period. Due to the development of accurate, efficient and stable software packages for ab initio simulations, DFT-based techniques are now routinely used in many industrial laboratories worldwide. It was therefore considered timely to organize a second 'Theory meets Industry' workshop. The meeting took place between 12-14 June 2007 at the Erwin-Schrödinger-Institute (ESI) for Mathematical Physics in Vienna (Austria). It was sponsored by the Universität Wien through the VASP (Vienna Ab-initio Simulation Program) project, the Center for Computational Materials Science Vienna, the Erwin-Schrödinger-Institute and the ESF Program 'Towards Computational Materials Design'. The program of the workshop was decided by an international advisory board consisting of Ryoji Asahi (Toyota Central Research and Development Laboratory), Risto Nieminen (Helsinki University of Technology), Herve Toulhoat (Institut Français du Pétrole), Erich Wimmer (Materials Design Inc.), Chris Wolverton (Ford Motor Co. and Northwestern University) and Jürgen Hafner (Universität Wien). The 35 invited talks presented at the meeting were divided equally between researchers from academia and from industry.

    This article provides a summary of the author’s research on human smuggling in Austria comparing migrants from Former Yugoslavia and the Russian Federation. The project’s primary intent was to collect more detailed information on migrants seeking asylum in Austria and their use of smuggling services to leave their home countries, including detailed information on demographics, force or threat of force by smugglers, routes and methods of transportation, costs of smuggling, payment methods, and deeper perceptual questions regarding the flight. Another central premise of the article discusses how current distinctions between human smuggling and human trafficking are arbitrary in many regards.

    Eucoleus boehmi (syn. Capillaria boehmi) is a canine trichuroid nematode affecting the upper respiratory airways (i.e., nasal cavity and paranasal sinuses) of dogs, foxes, and wolves. In the past few years, reports in dogs and wild canids have increased from across Europe, but data on its occurrence and distribution in Austria is scanty. A total of 47 red foxes (Vulpes vulpes) from the two westernmost provinces (Tyrol and Vorarlberg) of Austria were therefore examined for the presence of E. boehmi at necropsy. Eggs and adult nematodes were identified morphologically and molecularly (cox1) as E. boehmi. These nematodes were found in 26 (78.8 %) and 13 (92.9 %) foxes from Tyrol and Vorarlberg, respectively, with an overall prevalence of 83.0 % (39/47). The prevalence rate of infection recorded in this study is among the highest in Europe. These results suggest that foxes may represent an important source of infection for dogs and other canids, but further studies are needed to elucidate the transmission dynamics. PMID:27230019

    TBE is a public health problem well under control in Austria because of a mass vaccination programme. There have been 50-100 registered cases per year for many years, the vaccination rate of the population is currently 85 %. Special attention has to be given to the "older" generation 40 plus as this is the segment of the population where the majority of cases are observed annually. In comparison of the counties, Tyrol and Upper Austria finished first and second after a long time when Styria and Carynthia had observed most of the cases. For TBE applies the same as for Tetanus, namely the principle of disease control or disease elimination: The virus cannot be eliminated and vaccination provides individual protection. The both available TBE vaccines have proven to be very effective with an effectivity of 96-99 %, also when given irregular vaccinations the protection rate is still very high (>90 %). More than 4000 prevented cases between 2000 and 2011 prove this impressively.

    On July 15, 2012, adult Anopheles hyrcanus (Pallas 1771) mosquitoes were caught next to a farm barn near Rust, Burgenland, close to Lake Neusiedl National Park in eastern Austria. Six weeks later, adults of this invasive species were also found in a sheep shelter outside the village of Oggau and another 2 weeks later, in a horse barn in Mörbisch. The morphological typing was confirmed genetically by amplification and sequencing of a 1,404-bp-long fragment within the 5.8S ribosomal RNA gene, the internal transcribed spacer 2, and the 28S ribosomal RNA gene. Out of two A. hyrcanus pools analyzed, one was found positive for Plasmodium sp. A 460-bp-long sequence within the mitochondrial cytochrome b region revealed 100 % identity to a sequence of a Plasmodium parasite identified in a New Zealand bellbird (Anthornis melanura). The Austrian finding sites are close to the Hungarian border. In Hungary, the occurrence of A. hyrcanus was already reported in 1963. A. hyrcanus is considered the most important potential vector of malaria in southern France today. In Austria, sporadic autochthonous malaria cases could emerge, caused by immigration from malaria-endemic countries and heavy tourism. However, the broad population coverage of the Austrian health care system makes the reestablishment of endemic areas for malaria unlikely.

    Pharmaceutical expenditure continued to rise steadily in Austria during the 1990s and early 2000s despite a variety of reforms. However, recent reforms and initiatives have moderated the growth rate. These initiatives include transparent pricing of new drugs and generics, greater restrictions on the prescribing of new drugs and voluntary price reductions. Alongside this, there have also been initiatives to enhance rational and efficient prescribing. The lack of published data makes it difficult to fully analyze the impact of individual reforms. In addition, some reforms have only recently been introduced. Despite this, implications can be drawn for key stakeholder groups in the future. This includes pharmaceutical companies continuing to need to demonstrate substantially added benefit for their new drug to command average European prices. Otherwise, premiums will be restricted to a maximum 10% above the price of current standards. In addition, companies will need to continue to lower the price of their brands in interchangeable classes as standards become available as generics. The alternative will be prescribing restrictions. Further reforms will be needed in Austria to meet government growth targets for pharmaceutical expenditure of only 3-4% per annum, while continuing to fund new innovative drugs and increased volumes with greater prevalence of chronic diseases. Possible future measures and their implications for key stakeholder groups will also be discussed.

    The prevalence of Toxoplasma gondii in free-ranging chickens is a good indicator of the prevalence of T. gondii oocysts in the soil because chickens feed from the ground. The prevalence of T. gondii in free-range chickens (Gallus domesticus) from 11 Bio-farms in Austria was determined. Antibodies to T. gondii assayed by the modified agglutination test (MAT) were found in 302 of 830 (36.3%) chickens with titers of 1:10 in 50, 1:20 in 69, 1:40 in 53, 1:80 in 40, 1:160 or higher in 90. Hearts of 218 chickens with MAT titers of 10 or higher were bioassayed individually in mice. Tissues from 1183 chickens were pooled and fed to 15, T. gondii-free cats. Feces of the cats were examined for oocysts; 11 cats shed T. gondii oocysts. T. gondii was isolated from 56 chickens by bioassay in mice. Thus, there were 67 isolates of T. gondii from these chickens. Genotyping of these 67 isolates using the SAG2 locus indicated that all 33 were Type II. Phenotypically and genetically these isolates were different from T. gondii isolates from Brazil. None of the isolates was virulent for mice. This is the first report of isolation of T. gondii from chickens from Austria.

    Orf-virus (ORFV) is a parapoxvirus that infects small ruminants worldwide causing sporadic zoonotic infections, mainly transmitted by direct contact with sheep and goats. Following an ORFV case in a hunter of Alpine chamois (Rupicapra rupicapra), who did not report previous contact to domestic animals, a serological survey in Western Austria was conducted to assess the seroprevalence of ORFV in this species. In addition, this study also tested blood/tissue samples of chamois from different areas of the adjacent province of Bolzano/Northern Italy for antibodies against ORFV using immunofluorescence and ELISA. The observed seropositivity rates in the chamois tested on the Austrian and Italian side of the Alps were 23.5% and 9.5%, respectively, with a combined 95% confidence interval ranging from 0.0678 to 0.238. Although the prevalence was significantly lower than the one observed in Austrian sheep flocks, this study provided the first evidence that parapoxviruses have spilled over into chamois populations to a significant degree in the Tyrol regions of Austria and Italy.

    The objective of this study was to analyze in detail the time trend in prostate cancer mortality in the population of Tyrol, Austria. In Tyrol, prostate-specific antigen tests were introduced in 1988-1989 and, since 1993, have been offered to all men aged 45-74 years free of charge. More than three quarters of all men in this age group had at least one such test in the last decade. The authors applied the age-period-cohort model by Poisson regression to mortality data covering more than three decades, from 1970 to 2003. For Tyrol, the full model with age and period and cohort terms fit fairly well. Period terms showed a significant reduction in prostate cancer mortality in the last 5 years, with a risk ratio of 0.81 (95% confidence interval: 0.68, 0.98) for Tyrol; for Austria without Tyrol, no effect was seen, with a risk ratio of 1.00 (95% confidence interval: 0.95, 1.05). Each was compared with the mortality rate in the period 1989-1993. Although the results of randomized screening trials are not expected until 2008-2010, these findings support the evidence that prostate-specific antigen testing offered to a population free of charge can reduce prostate cancer mortality.

  17. Assessing the completeness of historical earthquake records in Austria and surrounding Central Europe

    Completeness of earthquake catalogues is a necessary condition for seismic hazard assessment since they are the base for the determination of a and b values of the Gutenberg-Richter relation. A new composite catalogue for Austria has been created based on data from four different catalogues of earthquakes in Austria (ZAMG, 2009; ACORN, 2004; Van Gils & Leydecker, 1991; Shebalin et al., 1998) including for the first time also data from surrounding regions such as the Vienna Basin outside Austria and a buffer region 100km outside the boundary of the Austria and Vienna basin. The used earthquake catalogues cover different record length with a first entry in 1048 AD. A reliable estimate of the a and b parameters of the Gutenberg-Richter Relation from this newly compiled dataset can be only given, if the new catalogue is checked for completeness. We determined the completeness intensity (Ic) and the completeness periods for the composite catalogue following the method described by Stepp (1972). This method supposes that the earthquake occurrences are Poisson-distributed and investigates (i) the minimum observation interval required to reach reliable estimates of mean recurrence periods, (ii) the time interval for which the catalogues may be regarded complete. Both intervals are functions of the intensity class. Ic is the smallest intensity above which every earthquake was recorded for a given time interval. The completeness period is the time interval in which the catalogue is complete for a given intensity range. As most of the catalogue's records are pre-instrumental data, this completeness check was performed on intensity data avoiding ambiguities arising from intensity-magnitude conversion. In a second step, we repeated the completeness check, but this time based on magnitudes in order to determine the influences of various magnitude conversions. For pre-instrumental events, we converted intensities into magnitudes using published intensity-magnitude conversion

  18. Ten years trends (1984-1993) in the precipitation chemistry in central Austria

    Since 1984, wet precipitation samples have been collected from five sampling sites in the eastern Alpine region of Austria. The chemical analysis performed included pH, NH 4+, Na +, K +, Ca 2+, Mg 2+, Cl -, NO 3- SO 42- and precipitation amount. These data were used to determine the 10 years (1984-1993) trends in precipitation chemistry and deposition for all major ions. The statistical data treatment by the use of least-squares linear regression revealed a significant decrease of sulfate and hydrogen ion concentrations and depositions at all sites in consideration (above 65% for hydrogen ion and over 33% for sulfate concentration and 40% for hydrogen and 36% for sulfate deposition). An effort is made to explain the acidity decrease not only by the parallel decrease of sulfate concentration but by the participation of the other constituents of the wet precipitation events. It has been found that when the hydrogen ion concentration decrease is stronger than that of sulfate ion concentrations a compensation mainly by ammonium ion concentration increase is achieved. On the contrary, when the hydrogen ion concentration decrease is weaker than sulfate concentration decrease, a calcium ion concentration decrease is present for the sites in consideration. The results obtained indicate that the precipitation chemistry in Central Austria follows the global trends of controlled reduction of atmospheric acidity.

  19. One decade of scientific studies of snow management on Austria's glacier ski resorts

    After the extremely warm summer of 2003, when melt affected Austria's glaciers up to the highest elevations, a scientific study on artificial modification of mass balance was initiated. It examined the effects of glacier covers and water injection, but also various grooming methods and snow accumulations based on monitoring and modelling of snow and energy balance. The results showed that covering the glacier was the most effective and cheapest method, saving about 70% of glacier melt in places. But covers are restricted to a small portion of the area, as they require high maintenance. In recent years, snow production and snow accumulation by wind drift have gained more and more importance, not only modifying glacier mass balance, but also guaranteeing an early season start. Initially about 35 ha of the glacier area (<10% of the ski resort area and less than one per mille of the total glacier area in Austria) were covered and later the area was reduced as snow production possibilities increased. Snow depots are often used as fun parks for snow boarders. Glacier covers are not primarily used for keeping snow for early season start on ski tracks, but to maintain the surface, especially close to cable car infrastructure, at a constant elevation and slope. Despite glacier dynamics, glacier surfaces with snow management show reduced decrease of surface elevation , both on piste and along lift tracks.

    In many European party systems, the radical right has challenged established patterns of political competition. This article studies the consequences of this by using the case of the Freedom Party of Austria (FPÖ) and data from Austria’s first national election study (AUTNES). It is found that the FPÖ has weakened Austria’s previously highly stable system of socio-structural and ideological divisions as expressed by the two mainstream parties, the People’s Party and the Social Democrats. In socio-structural terms, the FPÖ has undermined the Social Democrats’ support base. In ideological terms, FPÖ voters have distinct views on newer issues such as immigration, European integration and dissatisfaction with the political system, but its supporters’ views on Austria’s traditional conflicts surrounding the economy and social and religious values cannot explain the party’s success. These findings further our understanding of the transformation of political conflicts not just in Austria, but in Western Europe in general. PMID:26770003

    Mutations in the connexin 26 (Cx26) gene (GJB2) are associated with autosomal nonsyndromic sensorineural hearing loss. This study describes mutations in the Cx26 gene in cases of familial and sporadic hearing loss (HL) by gene sequencing and identifies the allelic frequency of the most common mutation leading to HL (35delG) in the population of eastern Austria. For this purpose we have developed and applied a molecular beacon based real-time mutation detection assay. Mutation frequencies in the Cx26 gene of individuals from affected families (14 out of 46) and sporadic cases (11 out of 40) were 30.4% and 27.5%, respectively. In addition to known disease related alterations, a novel mutation 262 G-->T (A88S) was also identified. 35delG accounted for almost 77% of all Cx26 mutations detected and displayed an allelic frequency in the normal hearing population of 1.7% (2 out of 120). The high prevalence of the 35delG mutation in eastern Austria would therefore allow screening of individuals and family members with Cx26 dependent deafness by a highly specific and semi-automated method.

    Disparities in earnings between Western and Eastern European countries are the reason for a well-established informal sector actively involved in collection and transboundary shipment activities from Austria to Hungary. The preferred objects are reusable items and wastes within the categories bulky waste, WEEE and metals, intended to be sold on flea markets. Despite leading to a loss of recyclable resources for Austrian waste management, these informal activities may contribute to the extension of the lifetime of certain goods when they are reused in Hungary; nevertheless they are discussed rather controversially. The aim of this paper is to provide objective data on the quantities informally collected and transhipped. The unique activities of informal collectors required the development and implementation of a new set of methodologies. The concept of triangulation was used to verify results obtained by field visits, interviews and a traffic counting campaign. Both approaches lead to an estimation of approx. 100,000 t per year of reusable items informally collected in Austria. This means that in addition to the approx. 72 kg/cap/yr formally collected bulky waste, bulky waste wood, household scrap (excluding packaging) and WEEE, up to a further 12 kg/cap/yr might, in the case that informal collection is abandoned, end up as waste or in the second-hand sector.

    Landslides frequently cause damage to agricultural land and infrastructure in Lower Austria - a province of Austria. Also settlements and people are threatened by landslides. To reduce landslide risks and to prevent the establishment of new settlements in highly landslide prone areas, the project "MoNOE" (Method development for landslide susceptibility modeling in Lower Austria) was set up by the provincial government. The main aim of the project is the development of methods to model rock fall and slide susceptibility for an area of approx. 15,900 km2 and to implement the resulting susceptibility maps into the spatial planning strategies of the state. Right from the beginning of the project a close cooperation between the involved scientists and the stakeholders from the Geological Survey of Lower Austria and the Department of Spatial Planning and Regional Policy of Lower Austria was established to ensure that method development and final susceptibility maps meet exactly the needs and demands of the stakeholders. This posed huge challenges, together with its realization in the large study area and a (heterogeneous) complex geological situation,. Limitations were given by restricted data availability (e.g. for geology or landslide inventories) in such a large study area. Rock fall susceptibility was modeled by a combined approach of determining rock fall release areas by empirical slope thresholds (dependent on geology) followed by empirical run-out modeling. Slide susceptibility was modeled based on the statistical approaches of weights of evidence (WofE) and generalized additive models (GAM) by two different research groups. Huge efforts were spent on the validation of all susceptibility models. In a later stage of the project we found that the best scientific maps are not necessarily the best maps to be implemented in spatial planning strategies. Thus, in close cooperation with the stakeholders, decisions had to be taken to find the best resolution of the maps

    Global trade of biomass-related products is growing exponentially, resulting in increasing ‘teleconnections’ between producing and consuming regions. Sustainable management of the earth's lands requires indicators to monitor these connections across regions and scales. The ‘embodied human appropriation of NPP’ (eHANPP) allows one to consistently attribute the HANPP resulting from production chains to consumers. HANPP is the sum of land-use induced NPP changes and biomass harvest. We present the first national-level assessment of embodied HANPP related to agriculture based on a calculation using bilateral trade matrices. The dataset allows (1) the tracing of the biomass-based products consumed in Austria in the year 2000 to their countries of origin and quantifying the HANPP caused in production, and (2) the assigning of the national-level HANPP on Austria's territory to the consumers of the products on the national level. The dataset is constructed along a consistent system boundary between society and ecosystems and can be used to assess Austria's physical trade balance in terms of eHANPP. Austria's eHANPP-trade balance is slightly negative (imports are larger than exports); import and export flows are large in relation to national HANPP. Our findings show how the eHANPP approach can be used for quantifying and mapping the teleconnections related to a nation's biomass metabolism. PMID:23576842

The population structure of 327 MRSA isolated between 2002 and 2012 was investigated. MRSA was assigned to 58 different spa types and 14 different MLST CC (multilocus sequence type clonal complexes); in particular, between 2007 and 2012, an increasing diversity in MRSA clones could be observed. The most abundant clonal complex was CC5. On the respective SCCmec cassettes, the CC5 isolates differed clearly within this decade and CC5/SCCmecI, the South German MRSA, predominant in 2002, was replaced by CC5/SCCmecII, the Rhine-Hesse MRSA in 2012. Whereas in many European countries MLST CC22-MRSA (EMRSA 15, the Barnim epidemic MRSA) is predominant, this clone occurred in Austria nearly 10 years later than in neighbouring countries. CC45, the Berlin EMRSA, epidemic in Germany, was only sporadically found in South-East Austria. The Irish ST8-MRSA-II represented by spa-type t190 was frequently found in 2002 and 2007, but disappeared in 2012. Our results demonstrate clonal replacement of MRSA clones within the last years in Austria. Ongoing surveillance is warranted for detection of changes within the MRSA population. PMID:27231237

    Triggered by the occurrence of acid rain a sampling network for the collection of wet deposition samples was initiated in Austria in the early 1980s. Now the data set covers a time period of slightly more than 30 years for the stations being operable since the beginning. Sampling of rain water and snow was and is performed with Wet and Dry Only Samplers (WADOS) on a daily basis. Chemical analysis of rain water and snow samples comprised anions (chloride, nitrate, sulfate) and cations (sodium, ammonium, potassium, calcium and magnesium) as well as pH and electrical conductivity. Here we evaluate and discuss temporal trends of both, ion concentrations and wet deposition data for twelve sampling stations, which were operable for most of the observation period of 30 years. As expected concentrations and wet deposition loads of sulfate and acidity decreased significantly during the last three decades - which is also reflected by a strong decrease of sulfur emissions in Austria and neighboring countries. Regarding nitrate the decrease of concentrations and wet deposition loads is less pronounced. Again this is in accordance with changes in emission data. In case of ammonium even less stations showed a significant decrease of annual average concentrations and depositions. Reasons for that might be twofold. On one hand emissions of ammonia did not decrease as strongly as e.g. sulfur emissions. Furthermore local sources will be more dominant and can influence the year to year variability. Seasonality of ion concentrations and deposition loads were investigated using Fourier analysis. Sulfate, nitrate, ammonium, acidity and also precipitation amount showed characteristic seasonal patterns for most of the sites and for concentrations as well as deposition loads. However the maxima in ion concentrations and deposition loads were observed during different times of the year. Concentrations of basic cations and chloride, on the contrary, hardly showed any seasonality. However, as

    Objectives To assess rates of neonaticide after the implementation of a preventative “anonymous delivery” law in mid-2001 in Austria. Women are allowed to access antenatal care and give birth in a hospital anonymously, without showing any ID and free of charge. Design Retrospective Study Setting A complete census of police-reported neonaticides was obtained from the police statistics of Austria, Sweden and Finland. Population All neonaticides reported to the police, 1991-2009. Main outcome measures Neonaticide rates pre- (1991-2001) and post- (2002-2009) anonymous delivery legislation per 100,000 births. Methods The Mann-Whitney U test for two independent samples was used to compare neonaticide rates during the pre-law period to the rates observed after the implementation of the new law for each country. Results On average the rate of police-reported neonaticides was 7.2 per 100.000 births (SD=3.5, median=7.1) in Austria prior to passage of the law and 3.1 per 100.000 births (SD= 2.1; median= 2.6) after passage of the law. A significant decrease in neonaticide was observed in Austria after the implementation of anonymous delivery (Mann-Whitney U test p=.017). Whereas the Finnish and Swedish rates were lower than the Austrian rates before and after the implementation of the Austrian law, they remained unchanged over the study period. Conclusion Our data demonstrate a significant decrease in the number of police-reported neonaticides in Austria after the implementation of anonymous delivery. Even though underlying factors associated with neonaticide are complex, the findings could indicate an effect of anonymous delivery in the prevention of this crime. PMID:23210536

    A project to establish an Austria-wide health-monitoring system for cattle was launched in 2006. Veterinary diagnostic data subject to documentation by law [Law on the Control of Veterinary Medicinal Products (Tierarzneimittelkontrollgesetz)] are standardized, validated, and recorded in a central database. This Austria-wide project is a collaboration among agricultural and veterinary organizations as well as universities, and is also supported by the Austrian government. In addition to providing information for herd management and preventive measures, further objectives of the project include estimating breeding values for health traits and monitoring the overall health status of Austria's cattle. To ensure a high level of participation from farmers and veterinarians, data security issues are extremely important. Valid data are the prerequisite for the efficient use of health records. The challenge hereby is to distinguish between farms with low frequencies of diseases and incomplete documentation and recording. Measures were undertaken to establish a routine monitoring system for direct health traits. A routine genetic evaluation for direct health traits as part of the joint breeding value estimation program between Germany and Austria was introduced for Fleckvieh in December 2010, based on diagnostic data from 5,428 farms with 147,764 Fleckvieh cows. In 2010 to 2011, the reporting of direct health traits as a compulsory part of performance recording and the breeding program was introduced as well. The overall challenge is the availability of sufficient valid direct health data for reliable breeding values. Practical experience gained in Austria in setting up a health registration system, focusing mainly on the availability of direct health data for breeding purposes with its successes and difficulties, is described.

    Austria was the first country in Europe implementing a universal mass vaccination program against rotavirus gastroenteritis (RV-GE) for all infants nationwide. Epidemiological data from a hospital based surveillance system show that incidence rates of children hospitalized with RV-GE decreased in 2009 compared to 2008 and compared to the prevaccination period 2001-2005. Decreasing hospitalization-rates from RV-GE were observed in children of all age groups, even in those not eligible for vaccination according to their age, suggesting herd immunity induced by universal mass vaccination against RV-GE. In 2009 the disease burden was highest in children below three months of age stressing the importance of the early start of the immunization course.

    Knowledge about suicide might be positively correlated with local suicide prevalence. This hypothesis was tested with a sample of 107 medical and social science undergraduates from Estonia, a country with a high suicide rate, using Hubbard and McIntosh's 1992 Revised Facts on Suicide Quiz. Compared (independent-groups t tests) with a sample of undergraduates from Austria, which has a markedly lower suicide rate, Estonians presented significantly higher overall knowledge about suicide (d = 0.39), particularly concerning demographic and epidemiological facts about suicide (d = 0.77) but not pertaining to clinical and interpersonal knowledge contents (d = -0.06). Study limitations and suggestions for extension of this preliminary inquiry are discussed. PMID:17918542

    During the hunting season of 2001-02, blood and spleen samples from 59 red deer (Cervus elaphus), 77 roe deer (Capreolus capreolus), four fallow deer (Dama dama), and five chamois (Rupicapra rupicapra) were collected from nine hunting districts (n = 133) and one deer farm (n = 12) in southern Austria. Sera were tested for antibodies against bovine viral diarrhea virus (BVDV) with an enzyme-linked immunosorbent assay (ELISA) and virus neutralization tests against three BVDVs and one border disease virus strain. Reverse transcriptase polymerase chain reaction was used for detection of pestivirus-specific RNA in spleen samples. Antibodies were detected in one serum sample when using ELISA and virus neutralization tests. Results of the virus neutralization tests of this sample provided strong evidence for the exposure to the BVDV-1 genotype. The spleen samples were negative for pestivirus-specific RNA.

    Landslides pose a significant hazard in the federal district of Lower Austria. The Geological Survey of Lower Austria is responsible for detailed site investigations as well as the planning and installation of protective measures. The most landslide prone area in Lower Austria is within the Rhenodanubian Flyschzone whose materials consist of alterations of fine grained layers (clayey shales, silty shales, marls) and sandstones. It exhibits over 6200 landslides within an area of approx. 1300 km². For areas susceptible to landsliding, protection works are not feasible or simply too costly. Therefore, monitoring systems have been installed in the past, most of them, however, are not operated automatically and require field visits for data readouts. Thus, it is difficult to establish any relation between initiating and controlling factors to gain a comprehensive understanding of the underlying process mechanism that is essential for any early warning applications. In this presentation, we present the design and first results of an automated landslide monitoring system in Gresten (Lower Austria). The deep-seated, slow moving Salcher landslide extends over approx. 8000 m² and is situated adjacent to residential buildings and infrastructure. This monitoring setup is designed to run for at least a decade to account for investigations of long term sliding dynamics and pattern. Historically the Salcher landslide has shown shorter phases with accelerated movements followed by longer phases with barely any movements. Those periods of inactivity commonly exceed regular project durations, thus it is important to cover longer periods. Such slope dynamics can be investigated throughout many parts in the world, thus this monitoring might allow to understand better also landslides with infrequent movement patterns. The monitoring setup consists of surface as well as subsurface installations. All installations are connected to permanent power supply, are taking the respective

    The Armed Forces Regional Medical Examiner in Europe is responsible for medico-legal death investigations for the U.S. military in 89 countries in Europe, Southwest Asia, and Africa. The Disaster Mortuary Affairs Response Team (DMART) is a rapidly deployable, experienced, multidisciplinary team patterned after the regional U.S. civilian Disaster Mortuary Response Teams. One of the first major challenges since the DMART's inception occurred on November 11, 2000. A fire in a funicular servicing a ski resort claimed 155 victims in a mountain tunnel in Kaprun, Austria. The DMART deployed to assist the Austrian authorities in the rapid recovery, examination, identification, and return of the remains. The DMART's considerable forensic expertise and inherent spirit of cooperation were instrumental in the successful management of the disaster, resulting in the positive identification and release of all 155 remains within 2 weeks of the incident.

    The WISDOM (Water Ice Subsurface Deposits Observations on Mars) Ground Penetrating Radar has been selected to be part of the ExoMars 2018 exobiological rover mission. A prototype has been tested during the Mars Simulation organized by the Austrian Space Forum in Alpine ice caves in Dachstein, Austria. This campaign provided the opportunity to validate methods developed to process WISDOM's data in a well-documented environment and to retrieve geometrical and quantitative information about the 3D structure and the electromagnetic properties of the subsurface. We estimate the ice thickness in different locations inside the ice caves, and show that this ice is formed of fine strata with different properties. Data analysis allows reconstructing the bedrock in a 3D environment where a complete survey was performed.

    In northeastern Austria there is a growing interest in increased utilisation of forest biomass for energy. This study focuses on soil properties and nutrient pool characteristics in deciduous forests in order to provide advice for forest management. We (i) quantified selected exchangeable cations in the soils of our study area and (ii) identified the effects of stand age, soil type, soil depth and soil pH on exchangeable cations and cation exchange capacity (CEC). Nine permanent Quercus petraea dominated plots on sandy, clayey cambisols and calcic chernozem were selected for our study. From each plot 18 soil samples were collected in a systematic grid by means of a soil corer with 70 mm diameter to a maximum depth of 60 cm. Soil pH, exchangeable mineral elements K, Ca, Mg, Na, Mn, Al, and Fe were determined in five geometric soil horizons. Statistical analysis showed that (i) forest age did not influence the exchangeable K content of the sandy soils; (ii) the exchangeable K content decreased with increasing stand age in clayey cambisols; (iii) exchangeable K, Na and Mg were higher in calcic chernozems and clayey cambisols (iv) exchangeable Fe was significantly higher in sandy forest soils except in the 60-80 years old stand; (v) exchangeable Fe was below detection limit in calcic chernozem soils. A comparison of exchangeable cations revealed that (i) Ca is the key element of base cations (ii) the content of base cations is strongly significantly higher in calcic chernozem soils (iii) calcic chernozem soils have the highest CEC. CEC ranged from 38 to 190 μmol/g in the entire research area. Base cations, acid cations and CEC differ with soil depth as followed (i) in sandy and clayey cambisols, CEC had a minimum in 20 cm depth and then increased with soil depth to 50 cm; (ii) CEC decreased steadily with soil depth in calcic chernozems. As expected, CEC is significantly positively correlated (Pearson correlation coefficient 0.661, P<0.01) with the pH of the soil. The

    Recent studies from Austria, France and Italy have shown that there is a poor adherence to the screening scheme for maternal Toxoplasma infections in pregnancy demonstrated by the fact that many recommended examinations are missed. This leads to undetected infections and limits our knowledge of incidence of the disease. We discuss the negative consequences of this situation on research on treatment effectiveness and the outcomes of congenital toxoplasmosis. The responsible public health institutions should assume responsibility for appropriate surveillance of the screening programme and take measures to improve screening adherence during pregnancy. Screening should start as early as possible in pregnancy and the latest test should be done at delivery. Screening schedule should allow distinguishing infections from the first, second and third trimester of pregnancy, as the risk of materno-foetal transmission and outcomes in case of foetal infections varies by time.

    In a pilot study, we aimed to identify the output of public health research by Austrian university and non-university research institutions and compare it with its translation into Austrian public health policy. A keyword search in PubMed was conducted for the period 2000 to 2013. The 'Public Health Newsletter' published by the Austrian Ministry of Health and the 'Health Reform Law 2013' were used as surrogate indicators for the translation of research into public health policy.A total of 97 publications in peer-reviewed journals showed a wide variation in topics. Comparing the research topics with the articles of the 'Public Health Newsletter', we found identity in the field of communicable diseases. The Health Reform Law 2013 confirms the importance of evidence-based decision-making; yet, it contains no direct mentioning of or relation to research results. Based on our methodology, moderate appreciation of research results at the political level could be found in Austria.

    Site selection is a crucial part of the work flow for installing seismic stations. Here, we report the preparations for a countrywide temporary seismic network in Austria. We describe the specific requirements for a multi-purpose seismic array with 40 km station spacing that will be operative approximately three years. Reftek 151 60 s sensors and Reftek 130/130S digitizers form the core instrumentation of our seismic stations which are mostly installed inside abandoned or occasionally used basements or cellars. We present probabilistic power spectral density analysis to assess noise conditions at selected sites and show exemplary seismic events that were recorded by the preliminary network by the end of July 2015.

    Two case studies involving the large-scale and deep-seated creeping of slopes in southern Austria are discussed. In both instances passive and active remedial measures were applied to help mitigate the landslide hazard. At the first site, geodetic and extensometer measurements indicated movements averaging up to > 50 cm/year with a maximum of 352 cm occurring in one year. Previous active measures consisting of rigid structures were destroyed and replaced by flexible protective engineering works. The second case study involves an intensive geodetic monitoring program. Here, averaged yearly velocities are found up to > 30 cm/year. Active remedial measures consisted of stream diversion and protective engineering works. Both cases show the importance of a comprehensive passive remediation program.

    2016-01-01

    Background Dirofilaria repens and D. immitis are filarioid helminths with domestic and wild canids as main hosts and mosquitoes as vectors. Both species are known to cause zoonotic diseases, primarily pulmonary (D. immitis), ocular (D. repens), and subcutaneous (D. repens) dirofilariosis. Both D. immitis and D. repens are known as invasive species, and their distribution seems associated with climate change. Until very recently, both species were known to be nonendemic in Austria. Methodology and Principal Findings Metadata on introduced and possibly autochthonous cases of infection with Dirofilaria sp. in dogs and humans in Austria are analysed, together with analyses of mosquito populations from Austria in ongoing studies. In Austria, most cases of Dirofilaria sp. in humans (30 cases of D. repens—six ocular and 24 subcutaneous) and dogs (approximately 50 cases—both D. immitis and D. repens) were most likely imported. However, occasionally infections with D. repens were discussed to be autochthonous (one human case and seven in dogs). The introduction of D. repens to Austria was confirmed very recently, as the parasite was detected in Burgenland (eastern Austria) for the first time in mosquito vectors during a surveillance program. For D. immitis, this could not be confirmed yet, but data from Germany suggest that the successful establishment of this nematode species in Austria is a credible scenario for the near future. Conclusions The first findings of D. repens in mosquito vectors indicate that D. repens presumably invaded in eastern Austria. Climate analyses from central Europe indicate that D. immitis also has the capacity to establish itself in the lowland regions of Austria, given that both canid and culicid hosts are present.

    The emergence and spread of infectious diseases in mid-latitudes, so far mainly observed in the tropics, considerably increase under the current situation of climate change. A recent example is the Usutu virus (USUV) outbreak in Austria. USUV is closely related to the West Nile virus in the U.S. and caused mass mortalities mainly of blackbirds (Turdus merula). The USUV flavivirus persists in a natural transmission cycle between vectors (mosquitoes) and host reservoirs (birds) and leads - once endemic in a population - to periodic outbreaks. In an epidemic model to explain the USUV dynamics in Austria 2001-2005, USUV dynamics were mainly determined by an interaction of bird immunity and environmental temperature. To investigate future scenarios, we entered temperature predictions from five global climate models into the USUV model and also considered four different climate-warming scenarios defined by the I ntergovernmental Panel on Climate Change, IPCC (20 different model-scenario combinations). We downscaled the 20 time series of predicted temperatures (through the year 2100) to represent the region around Vienna. Our simulations predict that USUV will persist in the host population after the epidemic peak observed in 2003. USUV-specific annual blackbird-mortality time series predict that the outbreak frequency increases successively from the beginning to the end of the century. Simulations of worst-case scenarios result in an endemic equilibrium with a decline of the blackbird population of about 24%. Additionally we calculated the annually averaged basic reproduction number for the period 1901-2100. The latter depict that undetected major outbreaks before 2000 were unlikely, whereas it is likely that the USUV becomes endemic after 2040.

    In January 2014, the first nationwide quality-assured breast cancer screening program addressing women aged ≥ 40 years was introduced in Austria. As part of the process of developing a patient information leaflet, the Evidence Based Medicine (EBM) Review Center of the Medical University of Graz was charged with the task of assessing the potential benefits and harms of breast cancer screening from the available evidence. Based on these results, key figures were derived for mortality, false-positive and false-negative mammography results, and overdiagnosis, considering Austria-specific incidence rates for breast cancer and breast cancer mortality. Furthermore, the current evidence regarding age limits and screening interval, which were the subjects of controversial public discussions, was analyzed. A systematic search for primary and secondary literature was performed and additional evidence was screened, e. g., evaluation reports of European breast cancer screening programs. On the basis of the available evidence and of the Austrian breast cancer mortality and incidence rates, it can be assumed that - depending on the age group - 1 to 4 breast cancer deaths can be avoided per 1,000 women screened in a structured breast cancer screening program, while the overall mortality remains unchanged. On the other hand, 150 to 200 of these 1,000 women will be affected by false-positive results and 1 to 9 women by overdiagnosis due to the structured breast cancer screening. Therefore, the overall benefit-harm balance is uncertain. If women from 40 to 44 or above 70 years of age are considered, who can also participate in the Austrian screening program, even a negative benefit-harm balance seems possible. However, with the implementation of quality standards in breast cancer screening and the dissemination of a patient information leaflet, an improvement in the medical treatment situation, specifically in terms of informed decision-making, can be expected.

  8. Cardiac rehabilitation in Austria: long term health-related quality of life outcomes

    2009-01-01

    Background The goal of cardiac rehabilitation programs is not only to prolong life but also to improve physical functioning, symptoms, well-being, and health-related quality of life (HRQL). The aim of this study was to document the long-term effect of a 1-month inpatient cardiac rehabilitation intervention on HRQL in Austria. Methods Patients (N = 487, 64.7% male, age 60.9 ± 12.5 SD years) after myocardial infarction, with or without percutaneous interventions, coronary artery bypass grafting or valve surgery underwent inpatient cardiac rehabilitation and were included in this long-term observational study (two years follow-up). HRQL was measured with both the MacNew Heart Disease Quality of Life Instrument [MacNew] and EuroQoL-5D [EQ-5D]. Results All MacNew scale scores improved significantly (p < 0.001) and exceeded the minimal important difference (0.5 MacNew points) by the end of rehabilitation. Although all MacNew scale scores deteriorated significantly over the two year follow-up period (p < .001), all MacNew scale scores still remained significantly higher than the pre-rehabilitation values. The mean improvement after two years in the MacNew social scale exceeded the minimal important difference while MacNew scale scores greater than the minimal important difference were reported by 40-49% of the patients. Two years after rehabilitation the mean improvement in the EQ-5D Visual Analogue Scale score was not significant with no significant change in the proportion of patients reporting problems at this time. Conclusion These findings provide a first indication that two years following inpatient cardiac rehabilitation in Austria, the long-term improvements in HRQL are statistically significant and clinically relevant for almost 50% of the patients. Future controlled randomized trials comparing different cardiac rehabilitation programs are needed. PMID:19995445

  9. Patterns of globalized reproduction: Egg cells regulation in Israel and Austria

    PubMed Central

    2012-01-01

    Since the successful introduction of in vitro fertilization in 1978, medically assisted reproduction (MAR) has proliferated in multiple clinical innovations. Consequently, egg cells have become an object of demand for both infertility treatment and stem cell research, and this raises complex legal, ethical, social and economic issues. In this paper we compare how the procurement and use of human egg cells is regulated in two countries: Israel and Austria. Israel is known for its scientific leadership, generous public funding, high utilization and liberal regulation of assisted reproductive technology (ART). Austria lies at the other extreme of the regulatory spectrum in terms of restrictions on reproductive interventions. In both countries, however, there is a constant increase in the use of the technology, and recent legal developments make egg cells more accessible. Also, in both countries the scarcity of egg cells in concert with the rising demand for donations has led to the emergence of cross-border markets and global 'reproductive tourism' practices. In Israel, in particular, a scandal known as the 'eggs affair' was followed by regulation that allowed egg cell donations from outside the country under certain conditions. Cross-border markets are developed by medical entrepreneurs, driven by global economic gaps, made possible by trans-national regulatory lacunae and find expression as consumer demand. The transnational practice of egg cell donations indicates the emergence of a global public health issue, but there is a general lack of medical and epidemiological data on its efficacy and safety. We conclude that there is need for harmonisation of domestic laws and formulation of new instruments for international governance. PMID:22913734

    Basic technical and economic examinations of Austrian mass waste landfills, concerning the recovery of secondary raw materials, have been carried out by the 'LAMIS - Landfill Mining Austria' pilot project for the first time in Austria. A main focus of the research - the subject of this article - was the first devotion of a pilot landfill to an integrated ecological and economic assessment so that its feasibility could be verified before a landfill mining project commenced. A Styrian mass waste landfill had been chosen for this purpose that had been put into operation in 1979 and received mechanically-biologically pre-treated municipal waste till 2012. The whole assessment procedure was divided into preliminary and main assessment phases to evaluate the general suitability of a landfill mining project with little financial and human resource expense. A portfolio chart, based on a questionnaire, was created for the preliminary assessment that, as a result, has provided a recommendation for subsequent investigation - the main assessment phase. In this case, specific economic criteria were assessed by net present value calculation, while ecological or socio-economic criteria were rated by utility analysis, transferring the result into a utility-net present value chart. In the case of the examined pilot landfill, assessing the landfill mining project produced a higher utility but a lower net present value than a landfill leaving-in for aftercare. Since no clearly preferable scenario could be identified this way, a cost-revenue analysis was carried out in addition that determined a dimensionless ratio: the 'utility - net present value quotient' of both scenarios. Comparing this quotient showed unmistakably that in the overall assessment, 'leaving the landfill in aftercare' was preferable to a 'landfill mining project' in that specific case. PMID:27170192

    The early medieval site Thunau am Kamp consists of a hill fort and a settlement with large burial ground at the bank of river Kamp. All these features are under archaeological investigation since many years. The settlement comprises many pit houses, some with stratigraphic order. Every pit house was equipped with at least one cupola oven and/or a hearth or fireplace. Sometimes the entire cupola was preserved. The site was occupied during the 9th and 10th AD according to potshards which seem to indicate two phases: In the older phase ovens were placed in the corner of the houses while during the younger phase they are found in the middle of the wall. In order to increase the archaeomagnetic data base 14 ovens have been sampled. They fill the temporal gap in the data base for Austria around 900 AD. Laboratory treatment included alternation field and thermal demagnetisations as well as rock magnetic experiments. The baked clay with was formed from a loess sediment has preserved stable directions. Apart from one exception the mean characteristic remanent magnetization directions are concentrated around 900 AD on the early medieval part of the directional archaeomagnetic reference curve of Austria (Schnepp & Lanos, GJI, 2006). Using this curve archaeomagnetic dating with RenDate provides ages between 800 and 1100 AD which are in agreement with archaeological dating. In one case archaeomagnetic dating is even more precise. Together with the archaeological age estimates and stratigraphic information the new data have been included into the database of the Austrian curve. It has been recalculated using a new version of RenCurve. The new data confine the curve and its error band considerably in the time interval 800 to 1100 AD. The curve calibration process also provides a probability density distribution for each structure which allows for posterior dating. This refines temporal errors considerably. Usefulness of such an approach and archaeological implications will be

    Basic technical and economic examinations of Austrian mass waste landfills, concerning the recovery of secondary raw materials, have been carried out by the 'LAMIS - Landfill Mining Austria' pilot project for the first time in Austria. A main focus of the research - the subject of this article - was the first devotion of a pilot landfill to an integrated ecological and economic assessment so that its feasibility could be verified before a landfill mining project commenced. A Styrian mass waste landfill had been chosen for this purpose that had been put into operation in 1979 and received mechanically-biologically pre-treated municipal waste till 2012. The whole assessment procedure was divided into preliminary and main assessment phases to evaluate the general suitability of a landfill mining project with little financial and human resource expense. A portfolio chart, based on a questionnaire, was created for the preliminary assessment that, as a result, has provided a recommendation for subsequent investigation - the main assessment phase. In this case, specific economic criteria were assessed by net present value calculation, while ecological or socio-economic criteria were rated by utility analysis, transferring the result into a utility-net present value chart. In the case of the examined pilot landfill, assessing the landfill mining project produced a higher utility but a lower net present value than a landfill leaving-in for aftercare. Since no clearly preferable scenario could be identified this way, a cost-revenue analysis was carried out in addition that determined a dimensionless ratio: the 'utility - net present value quotient' of both scenarios. Comparing this quotient showed unmistakably that in the overall assessment, 'leaving the landfill in aftercare' was preferable to a 'landfill mining project' in that specific case.

    Since the successful introduction of in vitro fertilization in 1978, medically assisted reproduction (MAR) has proliferated in multiple clinical innovations. Consequently, egg cells have become an object of demand for both infertility treatment and stem cell research, and this raises complex legal, ethical, social and economic issues.In this paper we compare how the procurement and use of human egg cells is regulated in two countries: Israel and Austria. Israel is known for its scientific leadership, generous public funding, high utilization and liberal regulation of assisted reproductive technology (ART). Austria lies at the other extreme of the regulatory spectrum in terms of restrictions on reproductive interventions.In both countries, however, there is a constant increase in the use of the technology, and recent legal developments make egg cells more accessible. Also, in both countries the scarcity of egg cells in concert with the rising demand for donations has led to the emergence of cross-border markets and global 'reproductive tourism' practices. In Israel, in particular, a scandal known as the 'eggs affair' was followed by regulation that allowed egg cell donations from outside the country under certain conditions.Cross-border markets are developed by medical entrepreneurs, driven by global economic gaps, made possible by trans-national regulatory lacunae and find expression as consumer demand. The transnational practice of egg cell donations indicates the emergence of a global public health issue, but there is a general lack of medical and epidemiological data on its efficacy and safety. We conclude that there is need for harmonisation of domestic laws and formulation of new instruments for international governance.

    The shallow Murtal aquifer south of Graz, Austria, provides easily withdrawable groundwater, which is supplied as drinking water without any chemical treatment. The aquifer is also used intensively by agriculture. Common agricultural management practices are the main source for diffuse nitrogen leaching and high groundwater nitrate concentrations. To safeguard the coexisting use of these two important resources, lysimeters are operated at the agricultural test site Wagna, Austria, and the influence of two beneficial management practices--low nitrogen input and organic farming--on nitrogen leaching towards groundwater is investigated. The technical lysimeter design as presented here consists of: (1) high-resolution weighing cells, (2) a suction controlled lower boundary condition for sucking off seepage water, thus emulating undisturbed field conditions, (3) comparative soil temperature, water content and matrix potential measurements inside and outside the lysimeter at different depths, (4) an installation of the lysimeters directly into test plots and (5) a removable upper lysimeter ring enabling machinery soil tillage. Our results indicate that oasis effects or fringe effects of the lysimeter cylinder on unsaturated water flow did not occur. Another lysimeter cultivated with lawn is operated for observing grass-reference evapotranspiration, which resulted in good agreement with calculated grass-reference evapotranspiration according to the FAO-Penman-Monteith method. We conclude that lysimeters installed at Wagna test site did not show any fringe effects and, thus, are appropriate tools for measuring water balance elements and nitrogen leaching of arable and grass land at point scale. Furthermore, our results for the period of 2005 to 2011 show that beneficial management practices reduced nitrate leaching and, hence, may allow for a sustainable coexistence of drinking water supply and agriculture in the Murtal aquifer.

    he Directive 2007/60/EC of the European Parliament and of the Council of 23 October 2007 on the assessment and management of flood risks (EFD) aims at the reduction of the adverse consequences for human health, the environment, cultural heritage and economic activity associated with floods in the Community. This task is to be achieved based on three process steps (1) preliminary flood risk assessment (finalised by the end of 2011), (2) flood hazard maps and flood risk maps (due 2013) and (3) flood risk management plans (due 2015). Currently, an interdisciplinary national working group is defining the methodological framework for flood risk management plans in Austria supported by a constant exchange with international bodies and experts. Referring to the EFD the components of the flood risk management plan are (excerpt): 1. conclusions of the preliminary flood risk assessment 2. flood hazard maps and flood risk maps and the conclusions that can be drawn from those maps 3. a description of the appropriate objectives of flood risk management 4. a summary of measures and their prioritisation aiming to achieve the appropriate objectives of flood risk management The poster refers to some of the major challenges in this process, such as the legal provisions, coordination of administrative units, definition of public relations, etc. The implementation of the EFD requires the harmonisation of legal instruments of various disciplines (e.g. water management, spatial planning, civil protection) enabling a coordinated - and ideally binding - practice of flood risk management. This process is highly influenced by the administrative organisation in Austria - federal, provincial and municipality level. The Austrian approach meets this organisational framework by structuring the development of the flood risk management plan into 3 time-steps: (a) federal blueprint, (b) provincial editing and (c) federal finishing as well as reporting to the European Commission.

    In January 2014, the first nationwide quality-assured breast cancer screening program addressing women aged ≥ 40 years was introduced in Austria. As part of the process of developing a patient information leaflet, the Evidence Based Medicine (EBM) Review Center of the Medical University of Graz was charged with the task of assessing the potential benefits and harms of breast cancer screening from the available evidence. Based on these results, key figures were derived for mortality, false-positive and false-negative mammography results, and overdiagnosis, considering Austria-specific incidence rates for breast cancer and breast cancer mortality. Furthermore, the current evidence regarding age limits and screening interval, which were the subjects of controversial public discussions, was analyzed. A systematic search for primary and secondary literature was performed and additional evidence was screened, e. g., evaluation reports of European breast cancer screening programs. On the basis of the available evidence and of the Austrian breast cancer mortality and incidence rates, it can be assumed that - depending on the age group - 1 to 4 breast cancer deaths can be avoided per 1,000 women screened in a structured breast cancer screening program, while the overall mortality remains unchanged. On the other hand, 150 to 200 of these 1,000 women will be affected by false-positive results and 1 to 9 women by overdiagnosis due to the structured breast cancer screening. Therefore, the overall benefit-harm balance is uncertain. If women from 40 to 44 or above 70 years of age are considered, who can also participate in the Austrian screening program, even a negative benefit-harm balance seems possible. However, with the implementation of quality standards in breast cancer screening and the dissemination of a patient information leaflet, an improvement in the medical treatment situation, specifically in terms of informed decision-making, can be expected.

    Creeping soft-rock landslides trigger various seismic signals which relate to key dynamics of the slope instability. A new seismic monitoring study is carried out at Pechgraben - Upper Austria, where a clay-shale rich mudslide was reactivated in summer 2013 after heavy rainfalls. The well geophysical instrumentation of the Pechgraben mudslide by the Geological Survey of Austria (LAMOND network including permanent ERT, GPS, piezometers, soil temperature/humidity and photomonitoring) is expected as a better basis for joint interpretation of seismic source processes. Seismic data are acquired by small-aperture (< 30 m) sparse seismic arrays. Potential events are recognized by frequency-time signatures in sonograms, where sonograms are spectrograms featuring a frequency-dependant noise adaptation that enhance the display of weak signal energy down to the noise threshold. Further signal evaluation follows an interactive scheme where semi-automated beam forming method enables for approximate source location. Three seismic arrays where deployed at Pechgraben in October 2015 for an eight days feasibility study. About 200 seismic signals potentially triggered by the landslide were manually picked on night-time measurements. Target signals occur in tremor-like sequences and have duration within 1 - 8 seconds. Local magnitudes are calibrated down to ML -1.5 (Wood-Anderson amplitude ≈ 0.1 μm in 100 m distance). Observed waveforms display high degree of similarity with seismic signals catalogued at other soft-rock landslides suggesting that a general typology of seismic source processes could be established for creeping soft-rock instabilities with potential further implications in landslide mitigation and forecasting.

    Soil organic matter (SOM) is an important resource in agriculture. It influences soil fertility, erosion processes and prevents soil degradation. However, SOM is strongly affected by climate change, soil conditions and management alterations. The presented study analyzes SOM changes in Austria on a regional scale in the "Marchfeld" and the "Muehlviertel". For quantification these SOM changes the model CCB (Candy Carbon Balance) was used. Based on a 1 square kilometer raster, the impact of specific site conditions on SOM are determined to characterize the study areas. Used as a main indicator for these conditions is the biologic active time (BAT). BAT describes the biologic activity for carbon cycling in top soils depending on soil and climatic conditions. High values of BAT indicate fast SOM reproduction rates. Hence, BAT changes over last years signpost the risk of SOM loss and can be used as an on-farm decision tool. The change of risks of SOM loss due to climate change is assessed by model results. Therefore, three climate scenarios are used to compute reproduction rates of SOM. "High risk-regions" can be identified for policy consulting. Different climate scenarios can help to develop best case and worst case results. First results show that the region "Marchfeld" had a higher change in BAT during last 2 decades comparing to the "Muehlviertel". A higher risk of SOM loosing is evident. Nevertheless, future scenarios predict a higher change of BAT for the "Muehlviertel". Apparently, the sensitivity of "Marchfeld" sites regard to climate change has been higher in the past and most BAT changes took place until now. With this method an evaluation of farm management in regard to SOM reproduction and recommendation of crop rotations for the future are possible. In conclusion, the aim of the project is a tool box for farmers and policy makers to evaluate present and future agricultural management. An examination of additional regions in Austria is planned.

    The European Water Framework Directive requires the surface and groundwater bodies in the EU to be back to good quality conditions by 2015. To elucidate the mean residence time (MRT), the recharge area and the potential source of contaminations in particular monitoring wells a combination of several tracers has to be applied at least over one year to answer these questions with confidence. For the implementation of this goal it is necessary that any measures to improve groundwater quality show an impact depending on the MRT. The two groundwater bodies "Grazer Feld" and "Leibnitzer Feld" in the southern part of Styria, Austria stretch out along the river Mur in the N - S direction and covers an area of 166 and 103 km2. The porous aquifer of 10 - 20 m (Grazer Feld) of 6 - 10 m (Leibnitzer Feld) thickness consists of sandy gravel and boulders. In both groundwater bodies are about 2/3 of the aquifer is covered by loam of variable thickness. The depth to water varies between 2 - 20 and 2 - 8 m, respectively. The mean precipitation rate is 900 mm/a. The groundwater runs more or less along the river Mur with a small gradient. The northern part of the Grazer Feld groundwater body is dominated by the urban structure of the city of Graz. The southern part and the groundwater body Leibnitzer Feld is impacted intensively by agricultural use. Due to the extensive agricultural use it contains high concentrations of nitrate and pesticides and shows other hydrochemical changes caused by urbanisation and industrial use. In 33 monitoring wells delta oxygen-18 was analysed four times during one year within the framework of the Austrian hydrochemical groundwater monitoring system. During one campaign 3H, 3H/3He, CFCs and SF6 was analysed in all wells. In addition, the same methods were applied on depth-resolved groundwater samples at selected wells (Kralik et al. 2011). The results of the 3H-input and 3H/3He-models support in both groundwater bodies the rapid water circulation (<5

Support groups existed in which the desire for more specialized services was voiced. In response to this situation, funding was received to develop a new structure for early disease detection and long term support for both the person with dementia and their caregivers. This article describes the development of the model of the Dementia Service Centres (DSCs) and the successes and difficulties encountered in the process of implementing the model in six different rural regions of Upper Austria. The DSC was described in the First Austrian Dementia Report as one of the potential service models for the future. PMID:24339114

    In many cases, composition and characteristics of hillslope sediments are of particular importance related to landslide research in low mountain areas. The interaction of geologic, geomorphologic, and hydrologic factors determines the susceptibility for mass movements, which is affected by human impact as well. The present study aims to investigate factors that control mass movements and natural and anthropogenic impacts. On March 8th 2009, a landslide of 30.000 to 50.000 m³ occurred that destroyed a large part of a sports ground in the village of Hintersdorf, municipality of St. Andrä-Wördern (Lower Austria). As a result of extensive water supply ground liquefaction was initiated and the slide mass moved in form of a mud flow about 200 m down slope. As a consequence a small forest area and a fishpond were destroyed and an adjacent road was damaged. Closely to the event, first studies started and showed that the Hintersdorf landslide was triggered by extensive water saturation combined with hydrostatic pressure inside the slide mass. Heavy and long-lasting rainfalls and the start of snowmelt caused strong seepage and soil water saturation. Furthermore, insufficient ground drainage and overflow of a small retention pond intensified the unfavourable impact on soil-mechanical stability. Further studies included archive data analyse, field survey, as well as laboratory analyse and showed that high landslide susceptibility at the Hintersdorf landslide site was caused by a bundle of factors that control the process: The sports ground was built nearby the head of a trough valley that collects interflow and surface run-off from the surrounding slopes. The Flysch bedrock is covered extensively by clayey slope deposits. Furthermore, in the area of the valley head a waste deposit was operated up to the 1980's that resulted in a thick waste filling there. The Hintersdorf sports ground was constructed in 1984 on top of the waste body. Preliminary results show that hillslope

    Incoherent societal adaptation to natural processes results in significant losses every year. A better knowledge of the spatial and temporal distribution of hazards and risks, and of particular hot spots in a given region or period, is essential for reducing adverse impacts. Commonly, different hazard and risk estimations are performed within individual approaches based on tailor-made concepts. This works well as long as specific cases are considered. The advantage of such a procedure is that each individual hazard and risk is addressed in the best possible manner. The drawback, however, consists in the fact that the results differ significantly in terms of quality and accuracy and therefore cannot be compared. Hence, there is a need to develop a strategy and concept which uses similar data sources of equivalent quality in order to adequately analyze the different natural hazards and risks at broader scales. The present study is aiming to develop such a platform. The project Risk:ATlas focuses on the design of an atlas visualizing the most relevant natural hazards and, in particular, possible consequences for the entire territory of Austria. Available as a web-based tool and as a printed atlas, it is seen as a key tool to improve the basis for risk reduction, risk adaptation and risk transfer. The atlas is founded on those data sets available for the entire territory of Austria at a consistent resolution and quality. A 1 m resolution DEM and the official cadastre and building register represent the core, further data sets are employed according to the requirements for each natural hazard and risk. In this contribution, the methodology and the preliminary results for fluvial and pluvial floods and their consequences to buildings for three selected test areas in different types of landscapes (rural, urban and mountainous) are presented. Flooding depths expected for annualities of 30, 100 and 300 are derived from existing data sets for fluvial floods and are computed

    Unmanned Aerial Vehicles (UAV) have become a standard tool for geodata collection, as they allow conducting on-demand mapping missions in a flexible, cost-effective manner at an unprecedented level of detail. Easy-to-use, high-performance image matching software make it possible to process the collected aerial images to orthophotos and 3D-terrain models. Such up-to-date geodata have proven to be an important asset in natural hazard management: Processes like debris flows, avalanches, landslides, fluvial erosion and rock-fall can be detected and quantified; damages can be documented and evaluated. In the Alps, these processes mostly originate in remote areas, which are difficult and hazardous to access, thus presenting a challenging task for RPAS data collection. In particular, the problems include finding suitable landing and piloting-places, dealing with bad or no GPS-signals and the installation of ground control points (GCP) for georeferencing. At the BFW, RPAS have been used since 2012 to aid natural hazard management of various processes, of which three case studies are presented below. The first case study deals with the results from an attempt to employ UAV-based multi-spectral remote sensing to monitor the state of natural hazard protection forests. Images in the visible and near-infrared (NIR) band were collected using modified low-cost cameras, combined with different optical filters. Several UAV-flights were performed in the 72 ha large study site in 2014, which lies in the Wattental, Tyrol (Austria) between 1700 and 2050 m a.s.l., where the main tree species are stone pine and mountain pine. The matched aerial images were analysed using different UAV-specific vitality indices, evaluating both single- and dual-camera UAV-missions. To calculate the mass balance of a debris flow in the Tyrolean Halltal (Austria), an RPAS flight was conducted in autumn 2012. The extreme alpine environment was challenging for both the mission and the evaluation of the aerial

    Since the social sick funds have only limited amounts of money at their disposal, whereas the pharmaceutical market is constantly growing, thorough evaluations have to be undertaken how contributions are to be spent to get adequate value for money and especially to gain utmost benefit for the patients. When deciding on whether a pharmaceutical is listed in the Code of Reimbursement or not, pharmacoeconomic studies are obligatory in two cases: for real innovations with substantial therapeutic benefit and for applications for inclusion in the Yellow Box, when there are no alternatives listed in the Yellow Box. On the basis of the pharmacoeconomic study a comprehensible and justifiable cost/use relation of the pharmaceutical applied for should be proven in comparison with therapeutic alternatives in Austria. However, a pharmacoeconomic study is always only one aspect among others deciding on reimbursement and price. Even though the pharmaceutical applied for is not included in the Code of Reimbursement, reimbursement is possible in special cases if there is no adequate pharmaceutical listed in the Code of Reimbursement and the pharmaceutical is absolutely needed for therapeutic reasons. In these cases prior approval from a chief medical officer is required. Pharmacoeconomic studies for the purpose of section sign 25 of the Rules of Procedure for publishing the Code of Reimbursement (VO-EKO) must meet the following requirements: From a methodical point of view both cost-effectiveness analyses and--in justified cases--cost-utility analyses may be used. Due to required accuracy and traceability incremental analyses are preferred. Medical and economic data underlying the pharmacoeconomic study have to show a high degree of validity and evidence. The perspective to be taken is that of the Austrian Health Insurance. When determining the therapeutic alternatives, the most frequent indication, the most purposeful medical dosage and the main group of affected patients have to

    Deformed Quaternary cave sediments, which are well protected from both the erosional processes occurring at the Earth's surface and anthropogenic activities, provide a detailed archive of paleoseismic events, as well as an opportunity to assess potential regional seismic hazards. Hirlatz Cave, which lies about 2 km SW of Hallstatt, in the Salzkammergut area of Upper Austria, formed in a Triassic carbonate platform in the Dachstein Nappe, part of the Northern Calcareous Alps. With an overall length of 101 km, this is the third largest cave system in Austria. The present study focuses on an approximately 6.8 m long x 3 m high outcrop of Quaternary deposits that lie 2.8 km southeast of the cave entrance, in the so-called Lehmklamm. The succession comprises alternating packages of (a) pale grey sediments 3-25 mm thick and (b) finely laminated (1-2 mm) alternations of grey and lighter and darker brown sediments in layers 10-34 mm thick. X-ray diffraction analyses of the unconsolidated, finely laminated clay-sized sediments show a varve-like layering of brighter, carbonate and quartz-rich, and darker, clay mineral-rich layers of fluvio-lacustrine deposits. Heavy mineral analyses indicate an amphibolite facies source area that underwent a greenschist facies overprint. This indicates that the crystalline Central Alps lying to the south of the cave was likely the source. The succession contains abundant millimetre to centimetre-sized seismogenically-induced flame and fishtail structures, domino-boudins and syn-slumping structures such as folds and faults (normal and thrust faults) with flanking structures. Geometric analogues that are 2-3 orders of magnitudes larger have been described close to the Dead Sea Fault (e.g. Alsop et. al., 2011). Quantitative techniques, such as the reconstruction of the aspect ratios of boudins, the fault system polarity, the variation coefficient of faults and kinematic balancing have been used to interpret the structures. This suggests that (i

    Loess/palaeosol sequences contain detailed information about palaeoenvironmental changes during the Quaternary. Furthermore, because of its long distance aeolian transport, which resets the luminescence signal to zero prior to deposition, loess is highly suitable for luminescence dating. This allows the determination of geodynamic processes with time. The loess deposits in the Kremser Feld (Lower Austria) are up to 30 m thick. The loess/paleosol sequence of Stratzing is situated at the eastern margin of the west-east elongated hill of the ‘Galgenberg'; this location is famous for its archaeological finds, e.g. the sculpture "Fanny", one of the oldest identifiable representations of the human figure (Neugebauer-Maresch, 1993). The loess profile examined here has a total depth of 7.5 m and is subdivided into 19 prominent horizons. For each horizon the grain size distribution, pH-value, total carbonate content, total organic content and sulphur content was derived in order to reconstruct the environmental conditions leading to sedimentation and soil formation. To set up a geochronological framework for the loess deposition and the subsequent soil formation, nine samples were dated by means of elevated temperature post-IR IRSL (Thiel et al., submitted). Besides a general discussion about the sedimentological data we will discuss horizon 18 in more detail; this is a paleosol rich in clay and poor in mineralic carbonate. The sulphur content is relatively high and indicates higher humidity and warmer climate, all making the unexpectedly low organic carbon content of particular interest. The luminescence ages reveal an important hiatus above this well-developed palaeosol (from ~ 100 to ~ at least 200 ka) clearly showing that this loess/palaeosol sequence is not a continuous record. This implies either significant erosion or lack of loess deposition in this area. Neugebauer-Maresch, C., 1993. Kunst und geistige Welt. - In: Neugebauer-Maresch, C., (ed): Altsteinzeit im

  10. A multi-proxy record of Lateglacial climatic and environmental changes from Lake Mondsee (Upper Austria)

    Within the frame of the ESF EuroCLIMATE project DecLakes (Decadal Holocene and Lateglacial variability of the oxygen isotopic composition in precipitation over Europe reconstructed from deep-lake sediments), the sediment record of pre-alpine Lake Mondsee (Upper Austria) has been investigated with a special focus on the Lateglacial. The use of a multi-proxy approach, including microfacies analysis, high-resolution -XRF element scanning, stable isotope analyses on valves of benthic ostracods, carbon geochemistry and analysis of pollen and ostracods enables the identification of major climatic fluctuations during this period. Furthermore, the parallel sampling strategy allows direct comparison of sensitivity of different proxies to climatic and environmental changes. The basal clastic-detrital facies of the profile is dominated by proglacial varves. The gradual onset of biochemical calcite precipitation is paralleled by a rapid shift in oxygen isotope ratios of benthic ostracod valves which marks the abrupt warming at the onset of the Lateglacial Interstadial. However, the allochthonous sediment input from the catchment shows no rapid shift but a gradual decrease. During the Allerød biozone sedimentation is dominated by homogeneous endogenic calcite with a very low detrital component. At the onset of the Younger Dryas cold period a marked decrease in oxygen isotope ratios within ca. 100 years occurs, followed by a reduction in the amount of endogenic calcite and the increase of detrital flux with a lag of about 100 years. The clear vegetational shift towards higher proportions of herbs and Juniperus and the frequency increase of detrital event layers lag the ^18O signal by about 250 years. In contrast, the rapid Holocene warming within 20-30 years is well reflected by the parallel ^18O rise and the establishment of a vegetation adapted to a warmer climate with the onset of massive calcite precipitation and the cessation of detrital input lagging by only few decades

    Pasterze Glacier is the largest glacier in Austria and the Eastern Alps. The glacier is located at the foot of Mt. Großglockner (3798 m a.s.l.), the highest peak in Austria, and is accessible rather easily by a high alpine road ending above the main glacier tongue. At present, the glacier covers an area of about 17 km2, has a length of 8.3 km, a maximum ice thickness of about 190 m and is characterized by two unequally sized glacier tongues. The main glacier tongue is c.4 km long and heavily covered by debris. Since the end of the Little Ice Age (LIA) at around AD 1850 this glacier receded by 2.1 km. During the last c.160 years the main glacier tongue lowered by some 250 m on average. The glacier surface flow velocity decreased substantially, i.e. for example by 32% between the time periods 2003-2006 and 2006-2009. Glacier recession revealed large areas of previously ice-buried bedrock as well as minerogenic and biogenic sediments. In this contribution we present a compendium of research results based on several projects related to pure proglacial but also paraglacial processes and landforms in the vicinity of the present glacier. We will discuss (a) rock slope adjustment processes and its causes influencing for instance the supraglacial debris cover of the main glacier tongue substantially, (b) landform dynamics in the outwash plain and adjacent slopes close to the present glacier terminus, (c) the role of dead-ice for the proglacial landsystem, (d) formation and rapid enlargement of rock outcrops within the ice-fall, and (e) related natural hazard aspects. A further aspect discussed here - which is rather particular for Pasterze Glacier - is the (e) biogenic material (peat lumps and wood fragments) which has been found in recently deglaciated terrain. This material provides valuable insight into past ecological, glaciological and climatological conditions. Further rapid back- and downwasting of this glacier is very likely due to lack of ice replenishment. The

    Introduction Due to the interaction between smoking and the virus and the antiretroviral therapy, the excess health hazard due to smoking is higher in HIV+ patients than in the general population. International studies suggest a higher prevalence of smoking in HIV+ subjects compared to the general population. It was the aim of the study to assess prevalence of smoking, to analyze determinants of smoking, and to evaluate readiness to quit in HIV+ patients in Germany and Austria. Material and Methods Consecutive patients with positive tested HIV status, smokers and non-smokers, who are treated in seven different HIV care centres in Austria and Germany were included. Nicotine dependence was assessed with the Fagerström Test for Nicotine Dependency (FTND), and stages of change by a standardized readiness to quit questionnaire. Self-reported smoking status was objectified by measuring exhaled carbon monoxide levels. Smokers who wanted to quit were offered a structured smoking cessation programme, and those who did not want to quit received a 1-minute consultation. After six months, the smoking status of all included subjects was reassessed. Results A total of 447 patients were included; the response rate was 92%. Prevalence of smoking was 49.4%. According to a multivariate logistic regression analysis, lower age, male sex, lower educational level, and smoking of the partner were significantly associated with the smoking status. According to the FTND, 25.3% showed a low (0–2 points), 27.6 a moderate (3–4 points) and 47.1% a high (5–10 points) dependency. Regarding stages of change, 15.4% of the smokers were in the stadium precontemplation, 48.4 in contemplation, 15.4 in preparation and 10.0 in the stadium action. 11.0% were not assignable in any stadium. Higher education level and lower grade of dependency were significantly associated with the wish to quit smoking. Six months after the baseline examination, smoking cessation visits (at least one session) was

    Up-to-date and frequent glacier outlines are a necessity for many applications within glaciology. While multispectral band ratios are a comparatively robust method for automatically classifying clean ice on a pixel-based level, semi- or fully automated glacier inventories are complicated by spectral similarities between classes such as debris-covered glacier ice and the surrounding bedrock and moraines, or between clean ice and turbid pro-glacial water. Most glacier inventories therefore require a great deal of manual correction. Here, we present a glacier inventory of the Hohe Tauern Mountains in the Central Eastern Alps in Austria. Numerous glaciers, including the Pasterze Glacier, which is the longest glacier in the Eastern Alps, shape this mountainous region. The mapping of glaciers is based on object-based image analysis (OBIA) using both high resolution (HR) satellite imagery from Landsat 8 and a digital elevation model (DEM) derived from Airborne Laser Scanning (ALS) data. We automatically classify clean ice, debris-covered ice and glacial lakes. Image objects are created by applying the multiresolution segmentation algorithm implemented in the eCognition (Trimble) software. The resulting image objects are classified using a combination of various features, whereby a focus was put on the selection of robust features that are ideally applicable for mapping large areas, for example spectral indices such as the Normalized Differenced Vegetation Index (NDVI), Normalized Difference Snow and Ice Index (NDSI), Normalised Difference Water Index (NDWI), Land and Water Mask (LWK) and a ratio of the SWIR and NIR spectral bands. The ability of OBIA to incorporate optical and elevation data and to individually address data-specific characteristics helps differentiate debris-covered ice from surrounding features not only by using spectral properties but also based on morphological and topographic parameters, while the inclusion of rulesets relying on contextuality, size

    Epilepsy is a devastating condition with a considerable increase in mortality compared to the general population. Few studies have focused on cause-specific mortality which we analyse in detail in over 4,000 well-characterized epilepsy patients. The cohort comprised of epilepsy patients ≥ 18, treated between 1970 and 2009 at the epilepsy clinic of Innsbruck Medical University, Austria, and living in the province of Tyrol, Austria. Epilepsy diagnosis was based on ILAE guidelines (1989); patients with brain tumor were excluded. Deceased patients and causes of death (ICD-codes) were obtained via record linkage to the national death registry. We computed age-, sex-, and period-adjusted standardized mortality rates (SMR) for 36 diagnoses subgroups in four major groups. Additional analyses were performed for an incidence cohort. Overall cohort: 4,295 patients, 60,649.1 person-years, 822 deaths, overall SMR 1.7 (95 % CI 1.6-1.9), highest elevated cause-specific SMR: congenital anomalies [7.1 (95 % CI 2.3-16.6)], suicide [4.2 (95 % CI 2.0-8.1)], alcohol dependence syndrome [3.9 (95 % CI 1.8-7.4)], malignant neoplasm of esophagus [3.1 (95 % CI 1.2-6.4)], pneumonia [2.7 (95 % CI 1.6-4.2)]. Incidence cohort: 1,299 patients, 14,215.4 person-years, 267 deaths, overall SMR 1.8 (95 % CI 1.6-2.1), highest elevated cause-specific SMR congenital anomalies [10.8 (95 % CI 1.3-39.3)], suicide [6.8 (95 % CI 1.4-19.8)], alcohol dependence syndrome (6.4 [95 % CI 1.8-16.5)], pneumonia [3.9 (95 % CI 1.8-7.4)], cerebrovascular disease at 3.5 (95 % CI 2.6-4.6). Mortality due to mental health problems, such as suicide or alcohol dependence syndrome, malignant neoplasms, and cerebrovascular diseases was highly increased in our study. In addition to aim for seizure freedom, we suggest improving general health promotion, including cessation of smoking, lowering of alcohol intake, and reduction of weight as well as early identification of psychiatric comorbidity in patients with epilepsy.

    The phenology of trees affects the productivity of forests making phenological representation an important component of ecosystem models. The response to cues in temperature and day length varies among provenances, with the differences among provenances not fully understood. We evaluated the accuracy of eleven budburst models for birch and Norway spruce in Germany, United Kingdom (UK), Austria and Finland; covering gradients in latitude, altitude and continentality. The models were not able to accurately predict the timing of budburst, especially in the Alps. Early budburst were in general predicted too early and late budburst predicted too late, hence were budburst predicted too early in UK and too late in Austria. Models to be used in climate change assessments should be able to capture extreme events since budburst that today are considered very early could become the norm in a warmer climate. Our results imply that the models accuracy varied with spring temperatures and along geographical gradients. Model complexity was in this study assumed to represent the models level of plant physiological realism. All phenological models contain empirical components, and the model performance is therefore to some degree dependent on the calibration data, and cannot be considered truly process-based. The more complex models were in general less able to capture the variation in budburst and their performance was more dependent on the calibration data. Four different calibration schemes were employed; models predicted budburst of birch more accurately when fitted with one site in Germany, while the models performed better for Norway spruce when fitted with multiple sites in Germany. Among the two best performing models were an empirical model based on spring temperatures and the Alternating model based on growing degree days with a dynamic forcing requirement. However, both models could be considered unsuitable for climate change impact assessments. The empirical model is for

    Landslides pose a serious threat to many communities in Austria. The region of Lower Austria is underlayed, amongst others, by the lithological units of the Flysch Zone and the Gresten Klippenbelt. Both are particularly affected by landslides and the majority of episodic occurrences are bound to these two units. The active Salcher landslide is situated at the western border of the municipality of Gresten and is embedded in the geologic transition zone of the respective lithological units. The landslide is a reactivated and deep seated complex landslide that endangers buildings, parts of a road and lifelines such as power and optical fiber lines, fresh and sewage water supplies. Its varying movement rates are in the order of a few centimeters per year and consequently are classified as slow to extremely slow. Despite biannual geodetic surveys, little is known about the dynamic behavior including the triggering and controlling factors and its internal structure. Surface and subsurface investigations were therefore carried out on that landslide. With the intention to detect morphological surface changes, comparative geomorphologic mapping and terrestrial laser scanning was performed. Additionally, surface kinematical information was acquired by historical documents and GNSS measurements. The detailed present soil-physical conditions and their relation to current dynamics were investigated by six drill cores and three inclinometer installations. Soil specimens were obtained by percussion drilling. Particle size distribution, and water and carbonate content were subsequently analyzed in the laboratory. In addition, dynamic probing was performed at 13 sites across the landslide body and resistance values were compared to textural findings. The soil specimens show a heterogeneous texture and large variations in carbonate and water content. Soil wedges, originating from local displacements, were determined in two drill cores.

    Within ten days of August 2008 a cluster of nine earthquakes was detected by the Zentralanstalt für Meteorologie & Geodynamik (ZAMG) and other institutions in adjacent countries in the northwestern region of Austria, which until then was unremarkable in terms of its naturally occurring seismicity. At that time, the events with estimated magnitudes between ≈2.0 and 3.8, were located at depths of about 10-20 km in the general vicinity of Braunau (≈13.5° E) between the Bohemian Massif and the Eastern Alps, in an area of elevated geothermal heatflow (80-90 mW/m^2) with active geothermal energy production. A relocation of these events with NonLinLoc (Probabilistic Non-Linear Location algorithm) and HypoDD (Double-Difference location scheme) using a 3D-velocity model (Δx,y,z=1 km) of Austria revealed a very dense clustering of these events, and resulted in anomalously deep foci within 10 km of the Moho. Coherent focal mechanisms with T-axes striking NE-SW were determined for the strongest of the events through both, waveform-inversion (gCAP) and P-wave onset polarities (HASH). Further, the waveforms of all events exhibit high similarity (corr. of > 80%), as is typically observed in conjunction with densely clustered seismicity. Using a crosscorrelation technique (Subspace Detection Algorithm) we found previously undetected, weaker events during that time span associated with the same cluster. Similarly deep, lower crustal seismicity in the northern Alpine foreland has previously been observed and investigated in the Swiss part of the Central Alps west of 10° E, where the deepest events have been found to closely follow the Moho of the subducting European lithosphere. With the cluster of events reported on in this study apparently being singular in time and space, and in the absence of additional events observed at comparable depths in the wider region, we at this point do not infer any conclusive information as to the reasons of the observed seismicity.

    In the region of South-Eastern Styria, Austria, a strong increase of summer temperature over the last decades was recognized by Kabas et. al. (Meteorol. Z./ 20 (3), 277-289, 2011). With climate change the temperature will further increase, so that the possibility for more frequent droughts in summer will rise. This leads to the question if, for example, a steppe climate similar to that in the neighboring Hungarian Pussta can evolve in this region. Drastic climatic changes will be accompanied by strong changes in the hydrological balance. Since the region is strongly influenced by agriculture and other non-climatic factors as well, these human impacts on the water cycle must be considered. The Wegener Center, University of Graz is studying the Raab catchment in South-Eastern Styria, Austria, as an example of a small catchment of the climate-sensitive southern Alpine foothills. The available data indicate that the region is vulnerable to droughts in summer, signalled by a strong temperature increase over the recent decades and a tendency of precipitation decrease. The main goals of this study are to explore how the water balance in the region is going to change in the future, what the most significant uncertainties are and where there might be thresholds towards drastic changes. In this poster we report on the first steps, which is to build up a hydrological model for the Styrian Raab valley based on the Water balance Simulation Model (WaSiM) of ETH Zurich, Switzerland. Within the calibration the focus is on low flow conditions in summer. Given that the model shows good results for the well observed recent decades, a sensitivity analysis for changes in specific (control) parameters of the surface water balance is conducted. This will include anomalies of temperature and precipitation, water use for irrigation, and others. This enables to explore how warmer temperatures or changes in irrigation and crops affect the catchment. Model analyses do not only focus on flow

    Air quality is a key element for the well-being and quality of life of European citizens. Air pollution measurements and modeling tools are essential for assessment of air quality according to EU legislation. The responsibilities of ZAMG as the national weather service of Austria include the support of the federal states and the public in questions connected to the protection of the environment in the frame of advisory and counseling services as well as expert opinions. The Air Quality model for Austria (AQA) is operated at ZAMG in cooperation with the University of Natural Resources and Life Sciences in Vienna (BOKU) by order of the regional governments since 2005. AQA conducts daily forecasts of gaseous and particulate (PM10) air pollutants over Austria. In the frame of the project AQA-PM (funded by FFG), satellite measurements of the Aerosol Optical Thickness (AOT) and ground-based PM10-measurements are combined to highly-resolved initial fields using regression- and assimilation techniques. For the model simulations WRF/Chem is used with a resolution of 3 km over the alpine region. Interfaces have been developed to account for the different measurements as input data. The available local emission inventories provided by the different Austrian regional governments were harmonized and used for the model simulations. An episode in February 2010 is chosen for the model evaluation. During that month exceedances of PM10-thresholds occurred at many measurement stations of the Austrian network. Different model runs (only model/only ground stations assimilated/satellite and ground stations assimilated) are compared to the respective measurements. The goal of this project is to improve the PM10-forecasts for Austria with the integration of satellite based measurements and to provide a comprehensive product-platform.

    This study compared genetic diversity of Toxoplasma gondii isolates from Portugal, Austria and Israel. For this, we genotyped 90 T. gondii isolates (16 from Portugal, 67 from Austria and 7 from Israel) using 10 nested PCR-restriction length polymorphism (RFLP) genetic markers and 15 microsatellite (MS) markers. By PCR-RFLP typing, 7 isolates from Portugal chickens were identified as type II (ToxoDB #1 or #3), 4 were type III (ToxoDB #2) and the remaining 4 isolates have unique genotype pattern were designated as ToxoDB #254. One mouse virulent isolate from a bovine fetus (Bos taurus) in Portugal was type I (ToxoDB #10) at all loci and designated as TgCowPr1. All 67 isolates from Austria and 7 from Israel were type II (ToxoDB #1 or #3). By MS typing, many additional genetic variations were revealed among the type II and type III isolates. Phylogenetic analysis showed that isolates from the same geographical locations tend to cluster together, and there is little overlapping of genotypes among different locations. This study demonstrated that the MS markers can provide higher discriminatory power to reveal association of genotypes with geographical locations. Future studies of the type II strains in Europe by these MS markers will be useful to reveal transmission patterns of the parasite.

    This study presents fossil-fuel related CO2 emissions in Austria and Czechoslovakia (current Czech Republic and Slovakia) for 1830–2000. The drivers of CO2 emissions are discussed by investigating the variables of the standard Kaya identity for 1920–2000 and conducting a comparative Index Decomposition Analysis. Proxy data on industrial production and household consumption are analysed to understand the role of the economic structure. CO2 emissions increased in both countries in the long run. Czechoslovakia was a stronger emitter of CO2 throughout the time period, but per-capita emissions significantly differed only after World War I, when Czechoslovakia and Austria became independent. The difference in CO2 emissions increased until the mid-1980s (the period of communism in Czechoslovakia), explained by the energy intensity and the composition effects, and higher industrial production in Czechoslovakia. Counterbalancing factors were the income effect and household consumption. After the Velvet revolution in 1990, Czechoslovak CO2 emissions decreased, and the energy composition effect (and industrial production) lost importance. Despite their different political and economic development, Austria and Czechoslovakia reached similar levels of per-capita CO2 emissions in the late 20th century. Neither Austrian “eco-efficiency” nor Czechoslovak restructuring have been effective in reducing CO2 emissions to a sustainable level. PMID:21461052

    Caves formed by rising sulfuric waters have been described from all over the world in a wide variety of climate settings, from arid regions to mid-latitude and alpine areas. H2S is generally formed at depth by reduction of sulfates in the presence of hydrocarbons and is transported in solution through the deep aquifers. In tectonically disturbed areas major fractures eventually allow these H2S-bearing fluids to rise to the surface where oxidation processes can become active producing sulfuric acid. This extremely strong acid reacts with the carbonate bedrock creating caves, some of which are among the largest and most spectacular in the world. Production of sulfuric acid mostly occurs at or close to the water table but also in subaerial conditions in moisture films and droplets in the cave environment. These caves are generated at or immediately above the water table, where condensation-corrosion processes are dominant, creating a set of characteristic meso- and micromorphologies. Due to their close connection to the base level, these caves can also precisely record past hydrological and geomorphological settings. Certain authigenic cave minerals, produced during the sulfuric acid speleogenesis (SAS) phase, allow determination of the exact timing of speleogenesis. This paper deals with the morphological, geochemical and mineralogical description of four very typical sulfuric acid water table caves in Europe: the Grotte du Chat in the southern French Alps, the Acqua Fitusa Cave in Sicily (Italy), and the Bad Deutsch Altenburg and Kraushöhle caves in Austria.

    A calibrated and validated dynamic material flow model of Austrian aluminum (Al) stocks and flows between 1964 and 2012 was developed. Calibration and extensive plausibility testing was performed to illustrate how the quality of dynamic material flow analysis can be improved on the basis of the consideration of independent bottom-up estimates. According to the model, total Austrian in-use Al stocks reached a level of 360 kg/capita in 2012, with buildings (45%) and transport applications (32%) being the major in-use stocks. Old scrap generation (including export of end-of-life vehicles) amounted to 12.5 kg/capita in 2012, still being on the increase, while Al final demand has remained rather constant at around 25 kg/capita in the past few years. The application of global sensitivity analysis showed that only small parts of the total variance of old scrap generation could be explained by the variation of single parameters, emphasizing the need for comprehensive sensitivity analysis tools accounting for interaction between parameters and time-delay effects in dynamic material flow models. Overall, it was possible to generate a detailed understanding of the evolution of Al stocks and flows in Austria, including plausibility evaluations of the results. Such models constitute a reliable basis for evaluating future recycling potentials, in particular with respect to application-specific qualities of current and future national Al scrap generation and utilization.

    This paper reports a recently finished, interdisciplinary project on rural wastewater management in Austria. The objective of the project was to study alternative wastewater management options based on separation of the wastewater into its constituent parts, and to compare them with conventional ones. Thereby, a feasibility study of both conventional and alternative options for wastewater management in six model regions was carried out. Life cycle costs and social acceptance were analysed by using a case study-based assessment approach. However, hygienic and environmental risks were evaluated on a more general level. In order to complement the findings, a survey on urine separation system users in the Solar City of Linz was conducted. Based on these assessments and empirical findings, the paper concludes that options using a full separation of all wastewater fractions should be considered with care. Options based on a separation of only grey water and black water or in the liquid/solid phase can offer ecological and financial advantages over conventional options. Further, options combining wastewater management and regional biogas plants were identified as an interesting solution. However, legal constraints restrict this option currently.

    Empirical evidence of the impact of contraceptive counselling and factors affecting women's contraceptive choices are limited. CHOICE (Contraceptive Health Research Of Informed Choice Experience) was a large-scale study in 11 European countries. Women in Austria aged 15-40 years considering a short-acting, reversible form of combined hormonal contraceptive were eligible to participate. The choices included the combined daily pill, weekly transdermal patch, and monthly vaginal ring. This study assessed and compared 2478 women's original preferences with their post-counselling choices and evaluated their perceptions and criteria for their choice. Women who were 'undecided' decreased from 18.1% pre-counselling to 3.2% post-counselling; significantly more women post-counselling chose the monthly ring (8.7% to 23.8%; difference 15.1%, 95% CI 13.3-16.8%; P<0.0001) or the weekly patch (6.2% to 7.8%; difference 1.7%, 95% CI 0.5-2.9%; P=0.0014). Women's primary reasons for choosing a method included 'easy to use' (daily pill, weekly patch and monthly ring) and 'still effective if I experience vomiting, diarrhoea' (weekly patch and monthly ring). Structured and balanced counselling led to changes in the method chosen.

    In this paper we present two heavily eroded tooth fragments found in Grub/Kranawetberg, a Gravettian excavation site near Stillfried, Lower Austria. Both fragments were found during wet screening of sediment taken from an area near a hearth. Overall, the cultural layer yielded a large number of stone tools and flakes as well as bony points and over sixty bone beads and bone bead fragments. They point to an absolute date of 24,400 to 25,400 BP. We present a description of the tooth fragments and identify them as remains of an early modern human. One of the fragments is a deciduous right first lower molar (84) and the other a deciduous left lateral upper incisor (62). Due to their characteristic shape and size, as well as the degree of attrition, both teeth could have belonged to one single individual--a possibility consistent with their position in the stratigraphic column. The incisor could be compared for its metrical dimensions to the few other contemporaneous Upper Palaeolithic findings showing an insignificantly smaller dimension in mesio-distal and bucco-lingual dimensions. Although the remains are limited they increase our very small sample of deciduous teeth for this time period, which is essential for a better understanding of possible evolutionary trends from the Upper Palaeolithic to the Mesolithic.

    In this study we assess the prediction of a range of runoff signatures for a consistent dataset. Daily runoff time series are predicted for 213 catchments in Austria by a regionalised rainfall-runoff model and by Top-Kriging, a geostatistical interpolation method that accounts for the river network hierarchy. From the runoff timeseries, six runoff signatures are extracted: annual runoff, seasonal runoff, flow duration curves, low flows, high flows and runoff hydrograph. The predictive performance is assessed by the bias, error spread and proportion of unexplained spatial variance of statistical measures of these signatures in cross-validation mode. Results of the comparative assessment show that the geostatistical approach (Top-Kriging) generally outperforms the regionalised rainfall-runoff model. The predictive performance increases with catchment area for both methods and all signatures, while the dependence on climate characteristics is weaker. Annual and seasonal runoff can be predicted more accurately than all other signatures. The spatial variability of high flows is the most difficult to capture followed by the low flows. The relative predictive performance of the signatures depends on the selected performance measures. It is therefore essential to report performance in a consistent way by more than one performance measure.

    In Austria, 700 women are diagnosed every year with ovarian carcinoma. Approximately 15% of the patients with epithelial ovarian cancer have a germline mutation in the BRCA1 or BRCA2 genes. The increased incidence of breast and/or ovarian cancer in genetically related family members has given rise to the term "hereditary breast and ovarian cancer syndrome" (HBOC). Some 25-55% of these in-family diseases are attributed to germline mutations of BRCA1 or BRCA2, and approximately 5-10% to other known tumor predisposition syndromes. The remaining persons may carry mutations in as yet unidentified genes. HBOC caused by BRCA1 and BRCA2 mutations is an autosomal dominant disorder with high penetrance. BRCA1 and BRCA2 encode for so-called tumor suppressor proteins. Inherited functional mutations of these genes cause loss of function of the respective allele. Loss of function of the second allele causes complete loss of the corresponding protein and facilitates the development of a malignancy.The Association of Gynecologic Oncology recommends that testing for a germline mutation in BRCA1 or BRCA2 should be offered to all patients with epithelial ovarian cancer. When mutations in BRCA1, BRCA2, or other cancer-susceptibility genes have been identified, patients with ovarian carcinoma can be treated with new, innovative therapies. This recommendation is intended as a standard guideline for genetic testing of patients with an ovarian carcinoma.

    Domestic cats can be infected with a variety of enteric protozoa. Genotyping of protozoan species, especially Giardia as the most common, can improve assessment of their relevance as zoonotic agents. For an overview on the occurrence of feline enteric protozoa, 298 faecal samples of cats from private households, catteries and animal shelters in Austria were collected. All samples were examined by flotation and using a rapid test for Giardia (FASTest). For the detection of Tritrichomonas blagburni, freshly voided faeces (n = 40) were processed using a commercial culturing system (InPouch TF-Feline). Genotyping was done at the β-giardin gene loci (each sample) and triosephosphate isomerase gene loci (positive samples) for Giardia and at the 18S rRNA gene (positive samples) for Cryptosporidium. Thirty-seven samples (12.4%) were positive for Giardia by flotation and/or using a rapid test. Cryptosporidium was present in 1.7%, Cystoisospora in 4.0%, Sarcocystis in 0.3% and T. blagburni in 2.5% of the samples. Genotyping revealed Giardia cati, the potentially zoonotic Giardia duodenalis and Cryptosporidium felis. Most of the infected cats had no diarrhoea. Cats from shelters were significantly more often infected than owned cats (p = 0.01). When comparing Giardia detection methods, the rapid test had a higher sensitivity than flotation. Polymerase chain reaction (PCR) results were mostly independent from the other two tests.

    A calibrated and validated dynamic material flow model of Austrian aluminum (Al) stocks and flows between 1964 and 2012 was developed. Calibration and extensive plausibility testing was performed to illustrate how the quality of dynamic material flow analysis can be improved on the basis of the consideration of independent bottom-up estimates. According to the model, total Austrian in-use Al stocks reached a level of 360 kg/capita in 2012, with buildings (45%) and transport applications (32%) being the major in-use stocks. Old scrap generation (including export of end-of-life vehicles) amounted to 12.5 kg/capita in 2012, still being on the increase, while Al final demand has remained rather constant at around 25 kg/capita in the past few years. The application of global sensitivity analysis showed that only small parts of the total variance of old scrap generation could be explained by the variation of single parameters, emphasizing the need for comprehensive sensitivity analysis tools accounting for interaction between parameters and time-delay effects in dynamic material flow models. Overall, it was possible to generate a detailed understanding of the evolution of Al stocks and flows in Austria, including plausibility evaluations of the results. Such models constitute a reliable basis for evaluating future recycling potentials, in particular with respect to application-specific qualities of current and future national Al scrap generation and utilization.

    Reports of CMhl infections in South American Camelids in Europe are only available from the United Kingdom and Switzerland. Knowing that CMhl infections can lead to severe disease resulting in death if combined with other diseases or stress, it was the aim of this study to assess prevalence data from camelids in Austria. In comparison to the previous studies a representative number of camelids was investigated nationwide. Data were assessed due to differences in geographical region, age, sex, species, and origin. A relatively high prevalence of 25.8% was recorded. CMhl was detected significantly more often in alpacas (Vicunja pacos) than in llamas (Lama glama) and more frequently in animals younger than 2 years. Additionally regional differences have been observed, which might be due to climatic differences and/or variations in insect vectors. In this study apperantly clinical healthy animals were shown to be infected with CMhl. Camelids infected with CMhl are a pathogen reservoir. The results of this study indicate different risk levels of infection between llamas and alpacas and between younger and older animals. The data presented underline the necessity of further studies on CMhlI infections in South American Camelids.

    Austria's mammalian wildlife comprises a large variety of species, acting and interacting in different ways as reservoir and intermediate and definitive hosts for different pathogens that can be transmitted to pets and/or humans. Foxes and other wild canids are responsible for maintaining zoonotic agents, e.g. Echinococcus multilocularis, as well as pet-relevant pathogens, e.g. Hepatozoon canis. Together with the canids, and less commonly felids, rodents play a major role as intermediate and paratenic hosts. They carry viruses such as tick-borne encephalitis virus (TBEV), bacteria including Borrelia spp., protozoa such as Toxoplasma gondii, and helminths such as Toxocara canis. The role of wild ungulates, especially ruminants, as reservoirs for zoonotic disease on the other hand seems to be negligible, although the deer filaroid Onchocerca jakutensis has been described to infect humans. Deer may also harbour certain Anaplasma phagocytophilum strains with so far unclear potential to infect humans. The major role of deer as reservoirs is for ticks, mainly adults, thus maintaining the life cycle of these vectors and their distribution. Wild boar seem to be an exception among the ungulates as, in their interaction with the fox, they can introduce food-borne zoonotic agents such as Trichinella britovi and Alaria alata into the human food chain.

    Dendrogeomorphic dating of historical debris-flow events is a highly valuable tool for improving historical records in the field of natural hazard management. Previous dendrogeomorphic investigations generally have focused on case studies of single torrents; however, regional investigations may offer a more accurate reconstruction of regional patterns of activity and therefore may have an advantage over individual cases. The aim of the study is to provide a regional reconstruction of debris-flow events for a site in the Northern Calcareous Alps of western Austria (Gamperdonatal, Vorarlberg) and to document spatial and temporal morphological changes in individual and neighboring torrents. Analysis of 442 trees (268 Pinus mugo ssp. uncinata, 164 Picea abies, and 10 Abies alba) allowed identification of 579 growth disturbances corresponding to 63 debris-flow events since A.D. 1839. The majority of growth disturbances were in the form of growth suppression or release (76%) owing to the nature of both the deposited material and the process characteristics. Regional patterns of event frequency indicated a paucity of activity in the early to mid-twentieth century and increased activity since A.D. 1948, whereby large events were followed by subsequent years of continued activity of smaller magnitude. Patterns of frequency could be attributed primarily to spatiotemporal changes in channel morphology, but may also be reflective of changes in transport conditions within the valley. This study provides the first regional investigation in the Austrian Alps and contributes to the documentation of tree responses to geomorphic disturbances in calcareous material.

    The hydrogeology of the deep-seated, slowly creeping Klasgarten rockslide in Austria is investigated in this study based on detailed surface and subsurface field data, laboratory analyses, and analytical and numerical simulations. Field data are derived from several deep exploration and monitoring boreholes, an exploration drift located within the rockslide, and geological and geomorphological mapping. Particular attention is given to the pore pressure measurements and their temporal and spatial variability. These pore pressure variations are controlled by a thin layer of clayey fault gouge (representing the basal shear zone of the rockslide), a high-permeability rockslide mass, and moderately fractured paragneissic bedrock. Variably saturated equivalent-continuum hydraulic conductivities and storage properties are derived from packer tests, laboratory tests and optical televiewer images. These data sets are used for two-dimensional numerical groundwater models to study the flow-field and pore-pressure variations caused by the reservoir water-level fluctuations, the transient groundwater infiltration from snowmelt and precipitation along the slope, and the exploration drift. The strongest pressure transients in the rockslide are caused by reservoir level fluctuations and not the natural groundwater recharge, even at substantial distances from the reservoir. The response times are very short and only a minor distance-dependent attenuation is observed. The results of this study are essential to analyse the hydromechanical control of the deformation behaviour of rockslides adjacent to hydropower reservoirs. Further, it helps to understand how the formation of a rockslide can change the original bedrock aquifer.

    Palaeobiogeographical and palaeodiversity patterns of scleractinian reef corals are generally biased due to uncertain taxonomy and a loss of taxonomic characters through dissolution and recrystallization of the skeletal aragonite in shallow marine limestones. Herein, we describe a fossil lobophylliid coral in mouldic preservation from the early middle Miocene Leitha Limestone of the Central Paratethys Sea (Vienna Basin, Austria). By using grey-scale image inversion and silicone rubber casts for the visualization of the original skeletal anatomy and the detection of distinct micromorphological characters (i.e. shape of septal teeth, granulation of septocostae) Parascolymia bracherti has been identified as a new species in spite of the dissolved skeleton. In the recent era, Parascolymia like all Lobophylliidae is restricted to the Indo-Pacific region, where it is represented by a single species. The new species proves the genus also in the Miocene Mediterranean reef coral province. A review of the spatio-temporal relationships of fossil corals related to Parascolymia indicates that the genus was probably rooted in the Eastern Atlantic‒Western Tethys region during the Paleocene to Eocene and reached the Indo-Pacific region not before the Oligocene. The revealed palaeobiogeographical pattern shows an obvious congruence with that of Acropora and tridacnine bivalves reflecting a gradual equatorwards retreat of the marine biodiversity center parallel to the Cenozoic climate deterioration.

    Since the year 2000, prospective dental students at Innsbruck Medical University, Innsbruck, Austria, have undergone both theoretical and practical preadmission exams, called the Dental Admission Test (DAT). The aim of this investigation was to assess the suitability and outcome of this selection practice. Five classes from 2001 to 2005 (N=97; forty-three female, fifty-four male) were retrospectively reviewed. DAT results were compared with student performance, gender, ability to graduate on time, and dropout rates. Furthermore, the influence of a previous medical degree was evaluated. The t-test was used to analyze correlations between the results of the DAT and the following: gender, students who graduated on time, and students who had previously completed a medical degree. Pearson's correlation coefficient (r) was applied to analyze correlations among test scores, age, and students' performance during the first clinical year. Students graduating on time were noted to have significantly better DAT results; students with a previous medical degree showed significantly better grades during their first clinical year. The difference between the performance of male and female applicants on the DAT was not significant. Correlation was found between DAT results and dental school performance (r=-0.462). We conclude that the DAT may reduce dropout rates by excluding applicants unlikely to be successful in practical courses and that DAT scores are a reliable tool to predict student performance during the first clinical year of dental school in Innsbruck.

    The Stambach mass movement (Austria) is a large and deep-seated mass movement in the Austrian Alps. It consists of a complex and compound mass movement system. The latest major reactivation of the Stambach mass movement was initiated in 1982 by rock fall activity that triggered an earth flow, which transformed into a mud flow. Six sediment cores were taken along the entire earth flow body showing a complex mixture of rock fall blocks and earth flow material. Whenever the earth flow was active, numerous wooden remains were buried within the flow mass. Thirteen of these remains sampled from the sediment cores were radiocarbon dated. The results indicate that the first activation of the Stambach mass movement occurred at least around 9750-9900 cal BP, followed by at least three further events during the Holocene, around 6310-5650, 2320-1880, and 1600-1180 cal BP. Accumulation of toppled rock towers in the head area of the earth flow, followed by a sudden collapse and saturated, undrained loading of the earth flow body, is the main trigger for activating the earth flow. These long lasting preparatory processes make it difficult to determine certain recurrence intervals. However, our data show that the Stambach mass movement was (and most probably still can be) reactivated after more than 3000 years of dormancy.

    With paragraph 95 of its new Penal Code, Austria has joined the ranks of those countries which, by statutory provision, lay down a general duty, which applies to everyone to render aid in a case of misadventure. This provision is to enhance the principle of rendering aid and assistance to a fellow human being in need, and to obligate everyone to exercise at least a minimum of solidarity with fellow-men and to undertake to save another person in danger of life or limb. The conception in legal policy and juristic application is shown by examples drawn from the literature. A case is reported in detail to demonstrate that the provision is also applicable to the doctor's activity in the hospital, starting out from the relatively wide scope of the concept of "misadventure". 95 of the Austrian Penal Code defines a typical crime by omission, the applicability therefore not being bound to the proof of an injurious outcome. The paper points out the particular difficulty in the differential diagnosis of alcoholisation - cranial trauma.

    The identification of extremely high indoor radon concentrations in the village Umhausen (Tyrol, Austria) initiated a scientific program to get information about the source and distribution of this noble gas. The high concentrations can not be related to U anomalies or large-scale fault zones. The nearby giant landslide of Koefels, with its highly fractured and crushed orthogneisses, are the only possible source of radon, despite the fact that the U and Ra content of the rocks is by no means exceptional. The reasons for the high emanation rates from the landslide are discussed and compared to results gained from a similar examination of the giant landslide of Langtang Himal (Nepal). The exceptional geologic situation in both cases, as well as the spatial distribution of different concentration levels, indicate that both landslides must be considered as the production sites of radon. Independent of the U and Ra contents of the rocks, the most important factors producing high emanation rates are the production of a high active surface area in circulation pathways for Rn-enriched soil air by brittle deformation due to the impact of the landslidemass. 37 refs., 4 figs., 1 tab.

    The objective of this study was to describe the experience of genetic testing in Austrian women with a BRCA1 or BRCA2 mutation in terms of preventive measures taken and incident cancers diagnosed. We collected clinical information on 246 Austrian women with a BRCA1 or BRCA2 mutation tested between 1995 and 2012 and followed 182 of them for an average of 6.5 years. Of the 90 women who were cancer-free at baseline, 21.4% underwent preventive bilateral mastectomy, 46.1% had preventive bilateral salpingo-oophorectomy, and 1 took tamoxifen; 58.8% of the at-risk women underwent at least one screening breast magnetic resonance imaging (MRI). Of the 85 women with breast cancer, 69.4% had a unilateral mastectomy or lumpectomy and 30.6% had a contralateral mastectomy. In the follow-up period, 14 new invasive breast cancers (6 first primary and 8 contralateral), 1 ductal carcinoma in situ case, 2 incident ovarian cancer cases, and 1 peritoneal cancer were diagnosed. In Austria, the majority of healthy women with a BRCA1 or BRCA2 mutation opt for preventive oophorectomy and MRI screening to manage their breast cancer risk; few have preventive mastectomy or take tamoxifen.

    In 1975 Austria introduced an obligatory serological screening of pregnant women for toxoplasmosis. Every woman is tested for antibodies at the beginning of her pregnancy and, in case of seronegativity, again in the second and third trimester. Basic tests are--alternatively--Dye test (SFT) and Indirect Fluorescent Antibody test IFAT); for further clarification, complement fixation test (CFT) and, particularly, various tests for detection of specific IgM and IgA antibodies and, in certain cases, for circulating antigen are carried out. If a primary Toxoplasma gondii infection of the pregnant woman is suspected, immediate therapy--with spiramycin before the 16th week of gestation and with pyrimethamin plus sulfadiazin after the 15th week of gestation--is carried out. Before the introduction of the screening programme, the incidence of prenatal toxoplasma infections was 50-70 per 10,000 births, presently it is below 1 per 10,000 births. Seropositivity among pregnant woman has decreased from almost 50% at the end of the seventies, to 36.7% in recent years (1989-1991). The percentage of suspected primary infection during pregnancy has, however, in the same period increased from less than 0.4% to 0.83%.

    Data of a tracer experiment with Bromide at one of the three lysimeters in Wagna/Austria are used to test the unsaturated zone solute transport model in MIKE-SHE. On April 4th, 2005 50 mg/l of Bromide were applied on the lysimeter operated with conventional farming. At this time the lysimeter was covered with bare soil until the start of the cultivation of pumpkin one month later. Concentrations at the lysimeter bottom (180 cm depth) were measured and, after break-through, plant uptake was measured to quantify mass recovery. The model using the Richards-Van Genuchten-Mualem approach is setup by comprehensive data of vegetation and soil hydraulic properties available at the lysimeter. Water movement simulation in the unsaturated zone is tested against measured seepage rates at the lysimeter bottom and soil water contents in different soil depths in a period of five years. A sensitivity study shows that, particularly in the quaternary gravel zone two different parameter sets are necessary to represent the different dynamics of water content and seepage. With both two sets the general dynamics of the tracer experiment are simulated well. However, the early rapid rise of the measured concentrations could not be represented by either parameter set, which indicates a complex pore system consisting of different flow paths in the gravel zone, e.g., a system of matrix flow and macro-pore flow.

    Attitudes towards suicide among medical students in Madras (India) and Vienna (Austria) were compared using the SUIATT questionnaire by Diekstra and Kerkhof (1989). Results show a very restrictive attitude in Madras, rejecting the right to commit suicide, nearly always judging suicide as a cowardly act, and rejecting the idea of assisted suicide. On the other hand, in Vienna a more permissive attitude was found. It is interpreted that the Indian pattern comes close to a "medical" or "disease model", with stronger emphasis on mental illness, impulsiveness and emotional aspects, whereas the Viennese pattern reflects a "theoretical", "rational model", concentrating on cognitive factors and minimizing the influence of mental illness, emotional difficulties and restrictions related to suicidal behaviour. This pattern may be influenced by the public discussion on assisted suicide and the right to die in Europe in the last decade. Possible relations to the risk for actual suicidal behaviour are discussed using respective answers concerning previous suicidal ideation and suicide attempts. The answers concerning suicidal ideation seem to be strongly influenced by the different attitude patterns: only 16.8% reported previous suicidal ideation in Madras, compared to 51.5% in Vienna, whereas the percentage of reported suicide attempts is equal in both centres (5.9%:4.9%).

    The study uses measured and calculated data on airborne pollutants, particularly nitrogen (ranges between 28 to 43kgN*ha(-1)*yr(-1)) and sulphur (10 to 18kgSO(4)-S*ha(-1)*yr(-1)), in order to assess their long-term (1992 to 2005) effects on bryophytes at the UN-ECE Integrated Monitoring site 'Zöbelboden' in Austria. Bryophytes were used as reaction indicators on 20 epiphytic plots using the IM monitoring method and on 14 terrestrial plots using standardised photography. The plots were recorded in the years 1992, 1993, 1998, and 2004/2005. Most species remained stable in terms of their overall population size during the observed period, even though there were rapid turnover rates of a large percentage of species on all investigated plots. Only a few bryophytes (Hypnum cupressiforme, Leucodon sciuroides) responded unambiguously to N and S deposition. Nitrogen deposition had a weak but significant effect on the distribution of bryophyte communities. However, the time shifts in bryophyte communities did not depend on total deposition of N and S.

    In this study 2058 blood samples from sheep of 150 flocks from the province of Tyrol were tested by ELISA and serum neutralisation tests for antibodies to ruminant pestiviruses. In the ELISA, positive results were obtained with 34.9% of individual sheep sera and in 89.3% of the sheep flocks. The prevalence in sheep and sheep flocks varied according to areas. Seroprevalence of pestiviruses was significantly (p < 0.05) higher in small ruminants pastured during summertime on the Alps. Comparative neutralisation studies were carried out on all positive blood samples with BVDV-1, BVDV-2 and BDV. 443 seropositive sheep samples exhibited clearly the highest titre against one of the pestivirus strains tested. 413 revealed the highest titres (2 or more fold) to BVDV-1, 6 to BVDV-2 and 24 to BDV. In some areas a very high rate of pestivirus seroprevalence could be found. This fact could be harmful to the BVDV-Elimination and Controlling Program in cattle in Austria.

    The rapid emergence and dissemination of carbapenemase-producing Enterobacter species and other members of the Enterobacteriaceae poses a considerable threat to the care of hospitalized patients and to public health. In this study, Enterobacter isolates demonstrating decreased susceptibility to carbapenems detected at the Division of Hygiene and Medical Microbiology, Innsbruck Medical University, between January 2006 and December 2010 were tested for bla(VIM-1), bla(NDM-1), bla(IMP), bla(KPC) and bla(OXA-48) using a multiplex PCR with published primers. PFGE was performed to determine the genetic relatedness. In total, 33 isolates (28 Enterobacter cloacae and 5 Enterobacter aerogenes) were collected during the study period. From 2006 to 2009, between two and seven isolates were found per year. In 2010, a significant increase of carbapenem-resistant strains was observed (n = 12). The bla(VIM-1) gene was detected in all 28 isolates of E. cloacae. Typing of E. cloacae by PFGE revealed three distinct clusters, the biggest of which contained 18 isolates. These findings demonstrate the emergence of VIM-1-producing Enterobacter in Tyrol, western Austria. The clonal relationship confirms the risk of spread of these organisms and their possible persistence over time.

    Reports of CMhl infections in South American Camelids in Europe are only available from the United Kingdom and Switzerland. Knowing that CMhl infections can lead to severe disease resulting in death if combined with other diseases or stress, it was the aim of this study to assess prevalence data from camelids in Austria. In comparison to the previous studies a representative number of camelids was investigated nationwide. Data were assessed due to differences in geographical region, age, sex, species, and origin. A relatively high prevalence of 25.8% was recorded. CMhl was detected significantly more often in alpacas (Vicunja pacos) than in llamas (Lama glama) and more frequently in animals younger than 2 years. Additionally regional differences have been observed, which might be due to climatic differences and/or variations in insect vectors. In this study apperantly clinical healthy animals were shown to be infected with CMhl. Camelids infected with CMhl are a pathogen reservoir. The results of this study indicate different risk levels of infection between llamas and alpacas and between younger and older animals. The data presented underline the necessity of further studies on CMhlI infections in South American Camelids. PMID:27529994

    Myrmekites have attracted the attention of petrographers over more than a century, and several genetic models have been proposed. We report on myrmekites from the Weinsberg granite of the Moldanubian zone of Upper Austria. Based on petrographic evidence, fluid-mediated replacement of alkali feldspar by myrmekite during the sub-solidus evolution of the granite is inferred. The replacement was metasomatic on the scale of the myrmekite domains requiring addition of sodium and calcium and removal of potassium from the reaction site. In contrast, silica and aluminum were conserved across the reaction front. Myrmekite formation appears to have been synchronous with and related to the hydration of orthopyroxene and concomitant replacement of primary magmatic plagioclase by biotite at around 500 °C. The evolution of the myrmekite microstructure and a peculiar composition zoning of the plagioclase constituting the myrmekite matrix is qualitatively explained by a model for discontinuous precipitation, which accounts for chemical segregation by diffusion within the reaction front and the propagation of the reaction front with finite mobility as potentially rate limiting processes. Constraints on the underlying reaction rates are derived from the preserved microstructure and chemical pattern. Crystal orientation imaging by electron backscatter diffraction reveals grain-internal deformation, which is primarily concentrated in the quartz and less pronounced in the plagioclase matrix of the myrmekite. This is interpreted as a growth feature related to different transformation strain at the segments of the myrmekite reaction front, where quartz and plagioclase are formed.

  16. Gravity Variations Induced by Changing Snowpack Observed at Conrad Observatory (Austria)

    Hydrological processes are usually associated with mass transport. This induces gravity variations observed by superconducting gravimeter (SG) masking the pure geodynamical signal. The present study focusses specifically on gravity variations due to snow accumulation and melting. Measurements of the gravity signal are taken from the SG GWR C025 located at the Conrad Observatory (Austria) in an underground laboratory at about 1000m altitude. In snow rich winters a snowpack of one meter in depth or even more can be observed at this location. Snow height is measured at three different locations to get an idea of its variability. At one place additionally the weight of the snow pack is determined which allows to calculate the snow water equivalent. Gravitational signals are rather different for the accumulation and ablation phase, not only due to the different time scales of these processes but also due to the complex way path of melting water entering the ground beneath of the SG. Two methods, rainfall admittance function and Bouguer reduction, are used to account for the effect of the snow pack. Both have their strengths and weaknesses. They work better for short-term mass transports than for long lasting ones because in the latter case interference with signals of other environmental processes gets more prominent. A few case studies including both accumulation and ablation of snow on different time scales will be discussed.

    This study presents a comparative, field-based hydrogeological characterization of exhumed, inactive fault zones in low-porosity Triassic dolostones and limestones of the Hochschwab massif, a carbonate unit of high economic importance supplying 60 % of the drinking water of Austria's capital, Vienna. Cataclastic rocks and sheared, strongly cemented breccias form low-permeability (<1 mD) domains along faults. Fractured rocks with fracture densities varying by a factor of 10 and fracture porosities varying by a factor of 3, and dilation breccias with average porosities >3 % and permeabilities >1,000 mD form high-permeability domains. With respect to fault-zone architecture and rock content, which is demonstrated to be different for dolostone and limestone, four types of faults are presented. Faults with single-stranded minor fault cores, faults with single-stranded permeable fault cores, and faults with multiple-stranded fault cores are seen as conduits. Faults with single-stranded impermeable fault cores are seen as conduit-barrier systems. Karstic carbonate dissolution occurs along fault cores in limestones and, to a lesser degree, dolostones and creates superposed high-permeability conduits. On a regional scale, faults of a particular deformation event have to be viewed as forming a network of flow conduits directing recharge more or less rapidly towards the water table and the springs. Sections of impermeable fault cores only very locally have the potential to create barriers.

  18. Deformation bands evolving from dilation to cementation bands in a hydrocarbon reservoir (Vienna Basin, Austria)

    2013-01-01

    In this study we analyzed five core samples from a hydrocarbon reservoir, the Matzen Field in the Vienna Basin (Austria). Deformation bands occur as single bands or as strands of several bands. In contrast to most published examples of deformation bands in terrigeneous sandstones, the reduction of porosity is predominantly caused by the precipitation of Fe-rich dolomite cement within the bands, and only subordinately by cataclasis of detrital grains. The chemical composition of this dolomite cement (10–12 wt% FeO) differs from detrital dolomite grains in the host rock (<2 wt% FeO). This observation in combination with stable isotope data suggests that the cement is not derived from the detrital grains, but precipitated from a fluid from an external, non-meteoric source. After an initial increase of porosity by dilation, disaggregation and fragmentation of detrital grains, a Fe-rich carbonate fluid crystallized within the bands, thereby reducing the porosity relative to the host sediment. The retention of pyrite cement by these cementation bands as well as the different degree of oil staining on either side of the bands demonstrate that these cementation bands act as effective barriers to the migration of fluids and should be considered in reservoir models.

    Palaeobiogeographical and palaeodiversity patterns of scleractinian reef corals are generally biased due to uncertain taxonomy and a loss of taxonomic characters through dissolution and recrystallization of the skeletal aragonite in shallow marine limestones. Herein, we describe a fossil lobophylliid coral in mouldic preservation from the early middle Miocene Leitha Limestone of the Central Paratethys Sea (Vienna Basin, Austria). By using grey-scale image inversion and silicone rubber casts for the visualization of the original skeletal anatomy and the detection of distinct micromorphological characters (i.e. shape of septal teeth, granulation of septocostae) Parascolymia bracherti has been identified as a new species in spite of the dissolved skeleton. In the recent era, Parascolymia like all Lobophylliidae is restricted to the Indo-Pacific region, where it is represented by a single species. The new species proves the genus also in the Miocene Mediterranean reef coral province. A review of the spatio-temporal relationships of fossil corals related to Parascolymia indicates that the genus was probably rooted in the Eastern Atlantic‒Western Tethys region during the Paleocene to Eocene and reached the Indo-Pacific region not before the Oligocene. The revealed palaeobiogeographical pattern shows an obvious congruence with that of Acropora and tridacnine bivalves reflecting a gradual equatorwards retreat of the marine biodiversity center parallel to the Cenozoic climate deterioration.

    The late Triassic period is recognized as one of the five major mass extinctions in the fossil record. All these important intervals in earth history are associated with excursions in C-isotope records thought to have been caused by perturbations in the global carbon cycle. The nature and causes of C-isotopic events across the Triassic-Jurassic (T-J) transition however, are poorly understood. We present several new high resolution organic C-isotope records from the Eiberg Basin, Austria, including the proposed Global boundary Stratotype Section and Point (GSSP) for the base of the Jurassic. The Triassic-Jurassic boundary interval in these records is characterized by the initial and main negative organic carbon isotope excursions (CIE) of up to 8‰. The initial and main CIEs are biostratigraphically constrained by first and last occurrences of boundary defining macro- and microfossils (e.g. ammonites). High resolution C-isotope records appear to be an excellent correlation proxy for this period in the Eiberg Basin. Pyrolysis analysis demonstrates increased Hydrogen Index (HI) values for organic matter coinciding with the initial CIE. Terrestrial organic matter influx and mass occurrences of green algae remains may have influenced the C-isotope composition of the sedimentary organic matter. This may have contributed to the extreme amplitude of the initial CIE in the Eiberg Basin.

    The present study is the first to investigate the relationships between a multiple set of paranormal beliefs and the acceptance of evolution, creationism, and intelligent design, respectively, in Europe. Using a questionnaire, 2,129 students at secondary schools in Vienna (Austria) answered the 26 statements of the Revised Paranormal Belief Scale (R-PBS) and three statements about naturalistic evolution, creationism and intelligent design (ID). The investigated Austrian students showed an average R-PBS score of 82.08, more than 50% of them agreed with naturalistic evolution, 28% with creationism, and more than a third agreed with ID, the latter two closely correlated with each other. Females generally showed higher belief scores in the paranormal, creationism and ID. The agreement with naturalistic evolution correlated negatively with religious belief, but not with other paranormal beliefs, whereas the two non-scientific alternatives to evolution significantly correlated with both traditional and paranormal beliefs. Religious belief showed a significant positive correlation with other paranormal beliefs. All subscales of paranormal belief decreased during the eight grades of secondary school, as did acceptance of creationism and ID. However, the acceptance of naturalistic evolution did not correlate with age or grade. Possible reasons and implications for science education and the biology curriculum at Austrian secondary schools are discussed.

    In August 2002 Austria was affected - like other European countries e.g. Germany, Czech Republic or Romania - by an extreme flood event, which occurred in Central Europe and brought rainfall of extraordinary extent and flood recurrence intervals from several years to more than 1000 years. Losses of human life and livestock and damages of infrastructure, buildings, public and private properties rose the public awareness and the demand for improvement of future flood mitigation measures. The Centre of Natural Hazards and Risk Management of the BOKU-University for Natural Resources and Applied Life Sciences, Vienna startet as a first initiative with a summary and review of all reports and documents upon the regional impact of the event. The summary includes the description of the meteorological boundary conditions, the flood generation and their frequencies. A broad range of disciplinary aspects like river engineering, river ecology, vegetation and biology, soil science and soil mechanics, rural and urban planning were involved. The inventory and interpretation of the damages forms a base for assessment of shortcomings and requirements for a successful flood protection strategy for the future. The holistic approach will result in improved regional water management plans and assists in the development of a sustainable, catchment based flood mitigation strategy. Besides the review of the event the presentation will comment on some lacks and shortcomings in the collected data base and will give hints for future demands in online monitoring requirements, on establishment and improvement of forecasting tools and of the information transfer to the emergency services.

    During the last decade medical education in Austria has seen more changes than in the whole of the previous century, with a complete overhaul of the structure of undergraduate curricula. Curricula now are organized in thematic, integrated modules, students have early patient encounters, the number of examinations has been drastically reduced, objective examinations have been introduced throughout the entire course as has skills training, and quality management is assured. As a consequence of the judgement of the European Court in 2005 against discrimination and in favour of equal treatment of EU citizens, free enrolment was abandoned and admission tests were introduced. In postgraduate training, licensing examinations are now obligatory. Crucial results from the point of view of students as well as with regard to the supply of manpower to the health care system are a sharp decrease in the formerly extremely long mean duration of study programmes and a sharp fall in drop-out rates. The now fully autonomous medical universities have the opportunity to intensify collaboration and to embark on a process of continuous renewal. Structural reform of undergraduate and postgraduate curricula will eventually ensure full equality of Austrian and other European medical qualifications. PMID:21818199

    Debris flows represent a severe hazard in alpine regions and typically result from a critical combination of relief energy, water, and sediment. Hence, besides water-related trigger conditions, the availability of abundant sediment is a major control on debris flows activity in alpine regions. Increasing temperatures due to global warming are expected to affect periglacial regions and by that the distribution of alpine permafrost and the depth of the active layer, which in turn might lead to increased debris flow activity and increased interference with human interests. In this contribution we assess the importance of permafrost on documented debris flows in the past by connecting the modeled permafrost distribution with a large database of historic debris flows in Austria. The permafrost distribution is estimated based on a published model approach and mainly depends of altitude, relief, and exposition. The database of debris flows includes more than 4000 debris flow events in around 1900 watersheds. We find that 27 % of watersheds experiencing debris flow activity have a modeled permafrost area smaller than 5 % of total area. Around 7 % of the debris flow prone watersheds have an area larger than 5 %. Interestingly, our first results indicate that watersheds without permafrost experience significantly less, but more intense debris flow events than watersheds with modeled permafrost occurrence. Our study aims to contribute to a better understanding of geomorphic activity and the impact of climate change in alpine environments.

    In a pilot study, we aimed to identify the output of public health research by Austrian university and non-university research institutions and compare it with its translation into Austrian public health policy. A keyword search in PubMed was conducted for the period 2000 to 2013. The 'Public Health Newsletter' published by the Austrian Ministry of Health and the 'Health Reform Law 2013' were used as surrogate indicators for the translation of research into public health policy.A total of 97 publications in peer-reviewed journals showed a wide variation in topics. Comparing the research topics with the articles of the 'Public Health Newsletter', we found identity in the field of communicable diseases. The Health Reform Law 2013 confirms the importance of evidence-based decision-making; yet, it contains no direct mentioning of or relation to research results. Based on our methodology, moderate appreciation of research results at the political level could be found in Austria. PMID:24664575

    Current management guidelines of HIV infected adults include recommendation to immunization against common vaccine preventable diseases. This effort is hindered by the scarce knowledge regarding the immunization status of this especially vulnerable patient group. This study analyzed the serostatus for pertussis, diphtheria and tetanus of more than 700 HIV infected individuals residing in Austria. These individuals were representative for the Austrian HIV cohort regarding sex, age, transmission risk and HIV progression markers. Overall, 73.6% were on suppressive HAART, mean CD4 cell count was 603c/μl. Seropositivity was 84% for diphtheria, 51% for tetanus and 1% for pertussis. Migrants had a lower chance of tetanus seropositivity (OR 0.30 (CI 0.21 to 0.43)). Increase in CDC classification were associated with increased diphtheria seropositivity (OR 1.42 (CI 1.02 to 1.98)) and a CD4 nadir<200c/μl was associated with increased pertussis seropositivity (OR 12.2, 95% CI 1.2 to 121). Importantly due to the well preserved immune status of nearly all participants vaccination would be feasible in the majority of the seronegative patients. In patients with a CD4 count>200c/μl, 95% lacked seroprotection to at least one of the antigens included in the triple vaccine Tdap and could be vaccinated. Thus, a proactive approach would largely reduce the number of patients at risk for these vaccine-preventable diseases.

    Domestic cats can be infected with a variety of enteric protozoa. Genotyping of protozoan species, especially Giardia as the most common, can improve assessment of their relevance as zoonotic agents. For an overview on the occurrence of feline enteric protozoa, 298 faecal samples of cats from private households, catteries and animal shelters in Austria were collected. All samples were examined by flotation and using a rapid test for Giardia (FASTest). For the detection of Tritrichomonas blagburni, freshly voided faeces (n = 40) were processed using a commercial culturing system (InPouch TF-Feline). Genotyping was done at the β-giardin gene loci (each sample) and triosephosphate isomerase gene loci (positive samples) for Giardia and at the 18S rRNA gene (positive samples) for Cryptosporidium. Thirty-seven samples (12.4%) were positive for Giardia by flotation and/or using a rapid test. Cryptosporidium was present in 1.7%, Cystoisospora in 4.0%, Sarcocystis in 0.3% and T. blagburni in 2.5% of the samples. Genotyping revealed Giardia cati, the potentially zoonotic Giardia duodenalis and Cryptosporidium felis. Most of the infected cats had no diarrhoea. Cats from shelters were significantly more often infected than owned cats (p = 0.01). When comparing Giardia detection methods, the rapid test had a higher sensitivity than flotation. Polymerase chain reaction (PCR) results were mostly independent from the other two tests. PMID:25762189

    Austria's mammalian wildlife comprises a large variety of species, acting and interacting in different ways as reservoir and intermediate and definitive hosts for different pathogens that can be transmitted to pets and/or humans. Foxes and other wild canids are responsible for maintaining zoonotic agents, e.g. Echinococcus multilocularis, as well as pet-relevant pathogens, e.g. Hepatozoon canis. Together with the canids, and less commonly felids, rodents play a major role as intermediate and paratenic hosts. They carry viruses such as tick-borne encephalitis virus (TBEV), bacteria including Borrelia spp., protozoa such as Toxoplasma gondii, and helminths such as Toxocara canis. The role of wild ungulates, especially ruminants, as reservoirs for zoonotic disease on the other hand seems to be negligible, although the deer filaroid Onchocerca jakutensis has been described to infect humans. Deer may also harbour certain Anaplasma phagocytophilum strains with so far unclear potential to infect humans. The major role of deer as reservoirs is for ticks, mainly adults, thus maintaining the life cycle of these vectors and their distribution. Wild boar seem to be an exception among the ungulates as, in their interaction with the fox, they can introduce food-borne zoonotic agents such as Trichinella britovi and Alaria alata into the human food chain.

    The area of Linz (Oberösterreich) is the most heavily polluted region in Austria, due to its chemical and steel industry. In 1981, a survey of volatile nitrosamines in ambient air performed by a local laboratory revealed levels of up to 5.45 micrograms/m3. This instigated the setting up of a systematic nitrosamine monitoring programme from February 1983 to May 1984, during which the validity of the analytical procedures was determined. A total of 363 air samples was collected over 200 days at 16 different locations in and around Linz. About 6% of the samples showed low nitrosamine contamination, with levels between 0.01 and 0.04 microgram/m3 of N-nitrosodimethylamine (NDMA), N-nitrosodiethylamine (NDEA), and N-nitrosomorpholine (NMOR). The lower limit of detection was 0.005 microgram/m3. It was not possible to confirm these low concentrations by high-resolution mass spectrometry. In some samples, thermal energy analyser-responsive material was observed, which may be due to the occurrence of C-nitro compounds.

    Predicted climate warming will likely reduce the area and increase the fragmentation of alpine snowbed habitats. The ability of snowbed plants to cope with such fragmentation will, among other things, depend on their reproductive strategy. With respect to the mating system, as a key component of reproductive strategies, the environmental conditions in arctic and alpine snowbeds have been hypothesized to select for high selfing ability due to short growing seasons and unpredictable pollinator service. In this study we evaluate whether the mating system strategies of seven typical snowbed forbs of the northeastern Calcareous Alps in Austria are in line with this hypothesis. Field-pollination experiments were conducted in order to study the effects of pollinator exclusion (bagging; all study species), emasculation and manual self- and cross-pollination (subset of study species) on seed set. Additionally, data on floral traits associated with the reproductive system such as anther and ovule numbers and pollen:ovule ratios were collected. Results demonstrate that selfing is not uncommon but by no means obligatory for snowbed plants: the study species display a wide range of mating system types, from predominately outcrossing to predominately selfing. The different reproductive strategies of regional snowbed plants are discussed in relation to their ability to cope with climate warming induced habitat fragmentation.

    For the first time, basic technical and economic studies for landfill mining are being carried out in Austria on the basis of a pilot project. An important goal of these studies is the collection of elementary data as the basis for an integrated ecological and economic assessment of landfill mining projects with regard to their feasibility. For this purpose, economic, ecological, technical, organizational, as well as political and legal influencing factors are identified and extensively studied in the article. An important aspect is the mutual influence of the factors on each other, as this can significantly affect the development of an integrated assessment system. In addition to the influencing factors, the definition of the spatial and temporal system boundaries is crucial for further investigations. Among others, the quality and quantity of recovered waste materials, temporal fluctuations or developments in prices of secondary raw material and fuels attainable in the markets, and time and duration of dumping, play a crucial role. Based on the investigations, the spatial system boundary is defined in as much as all the necessary process steps, from landfill mining, preparing and sorting to providing a marketable material/product by the landfill operator, are taken into account. No general accepted definition can be made for the temporal system boundary because the different time-related influencing factors necessitate an individual project-specific determination and adaptation to the facts of the on-site landfill mining project.

    Landslides represent significant hazards in the mountainous areas of Austria. The Regional Geological Surveys are responsible to inform and protect the population, and to mitigate damage to infrastructure. Efforts of the Regional Geological Survey of Lower Austria include detailed site investigations, the planning and installation of protective structures (e.g. rock fall nets) as well as preventive measures such as regional scale landslide susceptibility assessments. For potentially endangered areas, where protection works are not feasible or would simply be too costly, monitoring systems have been installed. However, these systems are dominantly not automatic and require regular field visits to take measurements. Therefore, it is difficult to establish any relation between initiating and controlling factors, thus to fully understand the underlying process mechanism which is essential for any early warning system. Consequently, the implementation of new state-of-the-art monitoring and early warning systems has been started. In this presentation, the design of four landslide monitoring and early warning systems is introduced. The investigated landslide process types include a deep-seated landslide, a rock fall site, a complex earth flow, and a debris flow catchment. The monitoring equipment was chosen depending on the landslide processes and their activity. It aims to allow for a detailed investigation of process mechanisms in relation to its triggers and for reliable prediction of future landslide activities. The deep-seated landslide will be investigated by manual and automatic inclinometers to get detailed insights into subsurface displacements. In addition, TDR sensors and a weather station will be employed to get a better understanding on the influence of rainfall on sub-surface hydrology. For the rockfall site, a wireless sensor network will be installed to get real-time information on acceleration and inclination of potentially unstable blocks. The movement

    Recently deciduous forests in northeastern Austria received increased attention as potential sources of biomass for energetic utilisation. There are still substantial deficits in the knowledge on carbon pools, -sequestration and -dynamics at these forest sites. The aim of our study was therefore to identify the main determinants which control soil organic carbon (SOC) pools in differently managed Quercus petraea dominated stands. We used the chronosequence approach to test the influence of stand age and management on the SOC pool. Soil samples were systematically collected from 14 plots by means of a 70mm hand auger to a depth of max. 60cm and separated into five geometric horizons. Narrow O-layers and signs of active bioturbation on most sites suggest rapid carbon mineralisation. Carbon pools of the aboveground biomass, the O horizon as well as fine and coarse roots and decay were determined. Soils in our study are cambisols derived from fossil alluvial deposits and loess and calcic chernozems derived from loess. Total soil carbon was determined by means of dry combustion and subtraction of soil inorganic carbon (SIC, by means of the Scheibler-method) if present. Mean SOC contents ranged from 5.3 kg.m-2 to10.4 kg.m-2 in the entire study area. The highest contents were found in calcic chernozem sites (7.2-10.4 kg.m-2) followed by loamy cambisol (6.1-6.8 kg.m-2) and sandy cambisol sites (5.3-6.9 kg.m-2). Among three chronosequence sets, we found strong positive correlations with total nitrogen (Pearson correlation coefficients of +0.91 to +0.93, p<0.01) and medium strong positive correlations with fine root content (+0.27 to +0.42, p<0.01). In both cases, stronger correlations were observed at cambisol sites. Further medium correlations were found between SOC and decay (+0.23 to +0.42, p<0.01), but no influence of the soil type was observed. As expected, SOC contents decreased significantly with increasing soil depth. Tighter C/N ratios in deeper horizons suggest

    Water economic studies in 1990s documented the importance of the springs draining relict rock glaciers for water supply and human consumption as well as for the ecosystem in alpine catchments in the Niederen Tauern Range, Austria. Recent studies confirm the hydrologic importance and show that in the easternmost subunit, the Seckauer Tauern Range, more than 40% of the area above 2000 m a.s.l. and up to 20% of the area above 1500 m a.s.l. drain through relict rock glaciers. Thus, the hydraulic properties of these alpine aquifers are considered to be important controls on the hydrology of these areas. Nevertheless their hydraulic properties and their inner structure are still poorly understood. Our hydrogeological research is carried out at the Schöneben Rock Glacier, located in Seckauer Tauern Range, Austria. This rock glacier is presumably relict although patches of permafrost might exist particularly in the upper part of the landform. The rock glacier covers an area of 0.11 km² and drains a total catchment of 0.76 km² with a maximum elevation of 2282 m a.s.l.. The rock glacier consists predominantly of gneissic sediments (mainly coarse-grained, blocky at the surface) and extends from 1720 to 1905 m a.s.l.. Discharge of the rock glacier spring is recorded since 2002. Electrical conductivity and water temperature used as natural tracers are continuously monitored since 2008. Furthermore, a tracer test with simultaneous injection of the fluorescent dyes naphthionate and fluoresceine at two injection points (one close to the front and one close to the rooting zone of the rock glacier) was performed. Recession analysis of the spring hydrograph reveals similarities to the flow dynamics of karst springs. The results exhibit on the one hand a slow base flow recession indicating a high storage capacity and on the other hand sharp discharge peaks immediately after rainfall events referring to a high hydraulic conductivity. Applying different analytic runoff models, the

    Landslides pose a major threat around the world, to both human life and infrastructure. This may be an even bigger issue in the near future, as an increased landslide activity is commonly listed as an expected impact of human-induced climate change, together with an increasing population growth and the further demand of living space. This requires sound and appropriate means of monitoring slopes prone to landsliding. Monitoring systems for investigating kinematic aspects of landslides aid in analyzing, interpreting, and ultimately understanding its spatio-temporal movement behavior. Landslides around the world greatly differ in terms of typology, movement patterns and geometry, thus, making it difficult to establish a one-fits-all monitoring solution. The linkage between multiple systems with automated instrumentation has often demonstrated the benefits of continuous surveillance in terms of predicting and early warning forthcoming landslide movements. Within this presentation, we introduce a recently established long-term monitoring site on the active Salcher landslide that makes use of an innovative multi-parameter system. The investigated landslide is situated in the municipality of Gresten (Austria) and extends over approx. 8000 m². This slow moving, deep-seated landslide is geologically located in the Gresten Klippenbelt (Helvetic Zone). The characteristic lithofacies are the Gresten Beds of Early Jurassic age that is covered by a sequence of marly and silty beds with intercalated sandy limestones. Together with the adjacent Flyschzone, this area exhibits one of the highest landslide susceptibility within Austria. The monitoring setup consists both of surface and subsurface systems. Surface measurements on multiple locations are performed with highly sensitive sensor networks that measure surface inclination and acceleration. These are wirelessly connected with each other, highly flexible and constructed with a high longevity, yet still at a high measurement

    Parameters of upward initiated lightning from tall objects are gaining increasing interest in recent years. This is a result of the installation of tall objects (wind turbines, radio towers, etc.) experiencing a high number of lightning flashes. Lightning current waveforms of flashes initiated from the Gaisberg Tower (GBT) in Austria are continuously measured since 1998. On average this radio tower (tower height 100 m) located on a small mountain (1287 m ASL) next to the city of Salzburg triggers about 60-70 flashes per year. More than 50% of the triggered flashes occurred during cold season (similar to so-called winter lightning in Japan) and more or less independent of the overall thunderstorm activity in Austria. Up to now, more than 800 flashes have been recorded by employing a 0.25 mΩ shunt at the tower top. Compared to inductive sensors, with their limited lower bandwidth, a shunt allows correct measurement of the slowly varying, low amplitude initial continuing current (ICC). ICCs are lasting for several hundreds of milliseconds and they are the main contributors to the transferred charge by a flash. Maximum transferred charge in a single flash was 783 C and this negative flash was recorded during cold season on October15th, 2012. Contrary to observations in winter lightning in Japan, where upward initiated flashes with very large charge transfer are predominantly bipolar, at the GBT 7 out of the 10 flashes exceeding a charge transfer of 300 C were negative, 2 were positive and 1 bipolar. Most of the flashes (93%) triggered by the GBT are of negative polarity, initiated by a positive upward propagating leader. But also positive (4%) and bipolar (3%) flashes are observed at the GBT. In case of negative lightning flashes, 45% of current records exhibit an ICC only, 23% of flashes has pulses of peak current exceeding 2 kA superimposed on the ICC, and return strokes following the ICC after a period of "no current" is observed in 32% of the events.

    Identifying Bacillus cereus as the causative agent of a foodborne outbreak still poses a challenge. We report on the epidemiological and microbiological investigation of three outbreaks of food poisoning (A, B, and C) in Austria in 2013. A total of 44% among 32 hotel guests (A), 22% among 63 employees (B) and 29% among 362 residents of a rehab clinic (C) fell sick immediately after meal consumption. B. cereus isolated from left overs or retained samples from related foods were characterized by toxin gene profiling, and molecular typing using panC sequencing and M13-PCR typing (in outbreak A and C). We identified two B. cereus strains in outbreak A, and six B. cereus strains, each in outbreak B and C; we also found Staphylococcus aureus and staphylococcal enterotoxins in outbreak A. The panC sequence based phylogenetic affiliation of the B. cereus strains, together with findings of the retrospective cohort analyses, helped determining their etiological role. Consumption of a mashed potatoes dish in outbreak A (RR: ∞), a pancake strips soup in outbreak B (RR 13.0; 95% CI 1.8-93.0) and for outbreak C of a fruit salad (RR 1.50; 95% CI 1.09-2.00), deer ragout (RR: 1.99; 95% CI 1.23-3.22) and a cranberry/pear (RR 2.46; 95% CI 1.50-4.03)were associated with increased risk of falling sick. An enterotoxigenic strain affiliated to the phylogenetic group with the highest risk of food poisoning was isolated from the crème spinach and the strawberry buttermilk, and also from the stool samples of the one B. cereus positive outbreak case-patient, who ate both. Our investigation of three food poisoning outbreaks illustrates the added value of a combined approach by using epidemiological, microbiological and genotyping methods in identifying the likely outbreak sources and the etiological B. cereus strains.

    Sensors, such as the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA's Terra satellite, are developed for monitoring global and/or regional ecosystem fluxes like net primary production (NPP). Although these systems should allow us to assess carbon sequestration issues, forest management impacts, etc., relatively little is known about the consistency and accuracy in the resulting satellite driven estimates versus production estimates driven from ground data. In this study we compare the following NPP estimation methods: (i) NPP estimates as derived from MODIS and available on the internet; (ii) estimates resulting from the off-line version of the MODIS algorithm; (iii) estimates using regional meteorological data within the offline algorithm; (iv) NPP estimates from a species specific biogeochemical ecosystem model adopted for Alpine conditions; and (v) NPP estimates calculated from individual tree measurements. Single tree measurements were available from 624 forested sites across Austria but only the data from 165 sample plots included all the necessary information for performing the comparison on plot level. To ensure independence of satellite-driven and ground-based predictions, only latitude and longitude for each site were used to obtain MODIS estimates. Along with the comparison of the different methods, we discuss problems like the differing dates of field campaigns (<1999) and acquisition of satellite images (2000-2005) or incompatible productivity definitions within the methods and come up with a framework for combining terrestrial and satellite data based productivity estimates. On average MODIS estimates agreed well with the output of the models self-initialization (spin-up) and biomass increment calculated from tree measurements is not significantly different from model results; however, correlation between satellite-derived versus terrestrial estimates are relatively poor. Considering the different scales as they are 9km² from MODIS and

    In recent decades, an increasing number of studies have aimed to shed light on the origin and spread of tuberculosis in past human populations. Here we present the results of a systematic palaeodemographic and palaeopathological survey of the Early Mediaeval population of Gars/Thunau (Lower Austria), which - at this stage - includes 373 individuals recovered at two archaeological sub-sites: a fortified settlement (including a necropolis) at the top of a hill - probably reserved for social and military elites; and a large riverine settlement at the foot of the hill, a so-called 'suburbium', where burials and an area of 'industrial' character were discovered. We recorded a great number of pathological alterations and a variety of 'classical' features of tuberculosis, such as vertebral destructions (Pott's disease) and joint destructions, and other pathological (unspecific) features probably linked with Mycobacterium tuberculosis infection (e.g. new bone formation at the inner surface of the ribs, endocranial alterations in the form of 'pits', and new bone formation at the cranial base). We hypothesize that the two contemporaneous (∼900-1000 AD) populations of Gars/Thunau differed not only in their social affiliation/condition, but also in the type and frequencies of their population-density-related infectious diseases (in particular tuberculosis). Moreover, we investigated the molecular genetic evidence of the causative organism in a few selected immatures exhibiting pathological changes at the inner wall of the cranium and discuss these findings in regard to the macroscopic features observed. Finally, we analysed carbon and nitrogen stable isotopes of both populations and strontium isotope ratios of the hill-top inhabitants in order to reconstruct certain aspects of diet and mobility to test our hypothesis concerning the specific social and/or military character of the site.

    Feline demodicosis is a rare parasitic condition caused by three different species of mites (Demodex cati, Demodex gatoi, and an unnamed species). D. gatoi inhabits the superficial skin layer (stratum corneum) and is easily transmitted between individual cats. A 2-year-old female spayed Cornish Rex was presented with alopecia and pruritus. The dermatological examination revealed bilateral alopecia and excoriations on trunk, limbs, and belly. The second cat in the household, a 3-year-old female spayed Thai, showed no clinical signs. Superficial and deep skin scrapings were performed and cellophane tapes applied, and living D. gatoi mites could be detected in both cats. Oral ivermectin (0.25 mg/kg every other day) was subscribed. Feces were collected from both cats and fecal flotation with sugar and zinc solutions performed. When compared to skin scrapings and cellophane tapes, D. gatoi was detected more frequently and in higher numbers in fecal samples. Our findings suggest that D. gatoi can be efficiently diagnosed with coproscopy, particularly in asymptomatic carrier animals. DNA was extracted from the flotation liquid, and a PCR protocol for the species verification was designed. A fragment targeting a 325-bp DNA fragment of the D. gatoi mitochondrial 16S rDNA gene was amplified with a 100% similarity to the D. gatoi entry in GenBank® (GI 421920216). We report the first finding of D. gatoi in Austria and propose fecal flotation as a valuable tool for mite detection. Fecal flotation liquid is suitable for DNA extraction and PCR-based species verification of D. gatoi.

    The Triassic-Jurassic (T-J) boundary interval coincides with enhanced extinction rates in the marine realm and pronounced changes in terrestrial ecosystems on the continents. It is further marked by distinct negative excursions in the δ13C org and δ13C carb signature that may represent strong perturbations of the global carbon cycle. We present integrated geochemical, stable-isotope and palynological data from the Kuhjoch section, the Global boundary Stratotype Section and Point (GSSP) for the base of the Jurassic (Northern Calcareous Alps, Austria). We show that the initial carbon isotope excursion (CIE), coinciding with the marine extinction interval and the formation of black shales in the western Tethys Eiberg Basin, is marked by only minor changes in kerogen type, which is mainly of terrestrial origin. Increased Total Organic Carbon (TOC) concentrations of 9% at the first half of the initial CIE coincide with Hydrogen Index (HI) values of over 600 mg HC/g TOC. The high correlation (with R2 = 0.93) between HI values and terrestrial Cheirolepidiaceaen conifer pollen suggests a terrestrial source for the hydrogen enriched organic compounds. The lack of major changes in source of the sedimentary organic matter suggests that changes in the δ13C org composition are genuine and represent true disturbances of the global C-cycle. The sudden decrease in total inorganic carbon (TIC) concentrations likely represents the onset of a biocalcification crisis. It coincides with a 4.5‰ negative shift in δ13C org values and possibly corresponds to the onset of CAMP related volcanic activity. The second half of the initial CIE is marked by the dramatic increase of green algae remains in the sediment. The simultaneous increase of the C org/N tot ratio suggests increased marine primary production at the final stage of black shale formation.

    The horizontal and vertical attenuation of the aerosol, the sky radiance, and the light absorption coefficient of the aerosol have been determined at wavelengths in the visible. From this set of data the following optical characteristics of the atmospheric aerosol could be derived: vertical optical depth, horizontal extinction and absorption coefficient, scattering phase function, asymmetry parameter, and single scattering albedo. Campaigns have been performed in Almería, Spain, and Vienna, Austria. The aerosol undergoes a considerable variation, as experienced by many other studies. Sometimes the vertical and the horizontal measurements gave similar data; on other days the aerosol at the surface and the aerosol aloft were completely different. The "clearest" aerosol always had the smallest single scattering albedo and thus relatively the highest light absorption. The optical characteristics of the aerosol in the two very different locations were very similar. Using the measured optical data, a radiative transfer calculation was performed, and the radiation reaching the ground was calculated. Comparing the values for the clear aerosol and the days with higher aerosol load, the radiative forcing due to the additional aerosol particles could be determined. The forcing of the aerosol at the ground is always negative, and at the top of the atmosphere it is close to zero or slightly negative. Its dependence on wavelength and zenith angle is presented. The preindustrial aerosol in Europe was estimated, and the forcing due to the present-day aerosol was determined. At the surface it is negative, but at the top of the atmosphere it is close to zero or positive. This is caused by the light absorption of the European aerosol, which is higher than in most other locations.

  4. Variability of solid load in the proglacial Fagge River, Tyrol (Austria)

    Glaciers can strongly affect sediment dynamics in high-mountain basins. They receive clastic material from rock walls by gravitational processes of various magnitudes (rock slides to rockfalls) or by subglacial erosion and transport sediments downvalley like a conveyor belt. At the glacier tongue the meltwater with its accompanying river load enters the proglacial system. Fine material is moving in suspension leading to turbid meltwater. The coarse fraction of the meltwater load is rolling or sliding as bedload on the proglacial channel bed. As glaciers are vulnerable to and thus indicators of climate change the sediment transfer systems in Alpine glacier basins will respond as well. Since the end of the Little Ice Age (LIA) around 1850 glacier in the European Alps have been melting down and their front lines have been retreating. Where the glacier ice is gone large amounts unconsolidated sediments are deposited (moraines, glaciofluvial deposits) and can easily be reworked during subsequent rain storms or snowmelt. As a consequence it is of great concern whether more solid load (higher sediment availability) or less solid load (trapping effect of proglacial lakes) is transported in proglacial rivers in the near future. Due to glacier retreat the amount of unconsolidated, sparsely vegetated sediments, which are prone to rapid remobilization, is increasing. Because more of these sediments are available for fluvial sediment transport, it is generally assumed that glacier retreat leads to an increase in sediment discharge from proglacial zones. The main objective of this study is to present a budget of the fluvial sediment transport within the proglacial Fagge River for the observation period 2012 - 2014. This quantification of solid sediment transport is needed for further investigations on the way to a holistic sediment budget for the whole glaciated catchment of the Gepatschferner in Tyrol/Austria.

  5. Improved Detection of Local Earthquakes in the Vienna Basin (Austria), using Subspace Detectors

    The Vienna Basin in Eastern Austria is densely populated and highly-developed; it is also a region of low to moderate seismicity, yet the seismological network coverage is relatively sparse. This demands improving our capability of earthquake detection by testing new methods, enlarging the existing local earthquake catalogue. This contributes to imaging tectonic fault zones for better understanding seismic hazard, also through improved earthquake statistics (b-value, magnitude of completeness). Detection of low-magnitude earthquakes or events for which the highest amplitudes slightly exceed the signal-to-noise-ratio (SNR), may be possible by using standard methods like the short-term over long-term average (STA/LTA). However, due to sparse network coverage and high background noise, such a technique may not detect all potentially recoverable events. Yet, earthquakes originating from the same source region and relatively close to each other, should be characterized by similarity in seismic waveforms, at a given station. Therefore, waveform similarity can be exploited by using specific techniques such as correlation-template based (also known as matched filtering) or subspace detection methods (based on the subspace theory). Matching techniques basically require a reference or template event, usually characterized by high waveform coherence in the array receivers, and high SNR, which is cross-correlated with the continuous data. Instead, subspace detection methods overcome in principle the necessity of defining template events as single events, but use a subspace extracted from multiple events. This approach theoretically should be more robust in detecting signals that exhibit a strong variability (e.g. because of source or magnitude). In this study we scan the continuous data recorded in the Vienna Basin with a subspace detector to identify additional events. This will allow us to estimate the increase of the seismicity rate in the local earthquake catalogue

    Deposits spanning the Radotruncana calcarata Taxon Range Zone at the Postalm section, Northern Calcareous Alps (Austria) are examined quantitatively for foraminiferal assemblages, especially the planktonic group. This study focuses on establishing a high resolution record spanning an 800 ka long stratigraphic interval from the active continental margin of the Penninic Ocean. The Postalm section displays reddish limestone- marl alternations representing precession cycles. For this study, 26 samples were taken bed by bed to allow a "per-precession-cycle" resolution (i.e., a minimum sample distance of ∼20 ka). Samples from limestones as well as from marls were examined for foraminiferal assemblages. Data suggest a typical, open marine Campanian foraminiferal community. The >63 µm fraction is dominated by opportunist taxa, i.e., members of Muricohedbergella and biserial planktic foraminifera. Archaeoglobigerina and "Globigerinelloides" appear frequently and benthic foraminifera are very sparsely found. The share of globotruncanids, representing more complex morphotypes amongst planktonic foraminifera, is recorded with 5-10%. The state of preservation of foraminifera from the Postalm section is moderate to poor. Differences between samples from marls and samples from limestone are evident, but do not reveal evidence that there was an influence on the postdepositional microfossil communities. However, data from microfossils showing moderate to bad preservation can still offer valuable insight into the palaeoenvironment and biostratigraphy. Information gathered on the composition of the planktonic foraminiferal assemblage confirms a low-to-mid-latitude setting for the Postalm section. As well resolved records of Late Cretaceous foraminifera assemblages are rare, the examination of the Radotruncana calcarata Taxon Range Zone provides some insights into variations and short term changes during the very short period of 800 ka.

    The importance of surface soil water (rooting zone) has become evident with climate change affecting rainfall patterns and crop production. The use of Cosmic Ray Neutron Probe (CRNP) for measuring surface soil water has become increasingly popular. The advantage of CRNP is that it is a non-invasive technique for measuring soil water content at an area-wide scale, in contrast to more conventional, techniques which measure mainly at field scale (point level). The CRNP integrates over a circular area of ca. 600 meters in diameter, to a depth of 70 cm, giving an average value for soil water content. Cosmic radiation interacting with the Earth's atmosphere continuously generates neutrons. At Earth's surface, these neutrons interact with surface water, and are slowed down. At sub-micrometer geometrics, these neutrons affect semiconductor devices, so they can be counted, slow and fast ones separately. From the difference in numbers between fast and slow neutrons, soil water content is calculated. As first in Austria, a CRNP (CRS 1000/B model) consisting of two neutron counters (one tuned for slow, the other one for fast neutrons), data logger and an Iridium modem, has been installed at Petzenkirchen research station of the Doctoral Programme for Water Resource Systems (TU Vienna) at 48.14 latitude and 15.17 longitude, 100 km west of Vienna, in late autumn 2013. The research station is located in an undulating agricultural landscape, characterized by heavy Cambisols and Planosols, and winter wheat and barley as main crops in winter, and maize and sunflower in summer. In addition, an in-situ soil moisture network consisting of 32 stations of Time Domain Transmissivity (TDT) sensors measuring soil water at 4 depths (0.05, 0.10,0.20 and 0.50 m) over an area of 64 ha has been established. This TDT network is currently being used to validate the use of the innovative CRNP technique. First results will be shown at the EGU 2014.

    The distribution of Y-chromosomal haplogroup G2a (G-P15) in present-day paternal lineages in Tyrol (Austria) was analyzed by applying a high-density regional sampling scheme that also covered remote mountain areas. There is evidence from ancient genetic data for a high frequency of Y-chromosomal haplogroup G in prehistoric populations of Central Europe, whilst nowadays levels well below 10% are routinely observed. A population sample comprising ∼3700 specimens was analyzed for Y-chromosomal variation by genotyping Y-SNPs and Y-STRs. The set of binary markers included nine SNPs specific for sub-lineages of haplogroup G. The frequency of haplogroup G in 2379 unrelated men born in Tyrol amounted to 11.3%. Nearly all of these Y chromosomes belonged to haplogroup G2a. The main sub-haplogroup within G2a was defined by the SNP L497 (G2a3b1c) and reached a population frequency of 8.6%. Although this average level is higher than reported for other countries the geographical distribution of haplogroup G-L497 showed a differentiated pattern with a clustered distribution within some alpine valleys, where maxima above 40% were found. Both, the estimation of coalescent times and a principle coordinates analysis based on RST values derived from Y-STR haplotypes from different sub-regions of Tyrol revealed evidence for an old settlement history associated with Y chromosomes belonging to haplogroup G in the Tyrolean Alps.

    Sediment production, storage and transport in glacial systems are spatially and temporally variable. Due to the ongoing global warming an accelerated glacial retreat is expected, leading to an exposure of unconsolidated sediments. Additionally, a higher sediment production from destabilised rock walls caused by permafrost degradation and glacial debuttressing is expected. At least those paraglacial processes become more important in alpine catchments in the near future. But, there is still a knowledge gap on the quantification of sediment transporting processes in those regions. The research questions we are focussing on are part of the PROSA project ("High-resolution measurements of morphodynamics in rapidly changing Proglacial Systems of the Alps") and are investigated at the Gepatschferner glacier. The Gepatschferner is located in the Eastern European Alps at the south end of the Kaunertal valley. It is the second largest glacier in Austria (15.7 km², 2012). The Gepatschferner is drained by the Fagge River. In this presentation we will focus on two main components of the sediment budget of the Gepatschferner: the input to and the output from the glacier system. The sediment input from the surrounding rockwalls to the glacier is observed by comparing multi-temporal airborne LiDAR DEMs (2006, July 2012, September 2012) to determine sediment delivery by rockfall. In 2012 a gauging station was installed at the Fagge River in front of the glacier outlet in oreder to determine the glacio-fluvial output of sediment from the glacier system. During the ablation periods from 2012 to 2014 the water level was recorded. At different stages the discharge was measured and a reliable stage-discharge relation could be established. That relation was used in combination with the recorded stage for the computation of the hydrograph in each season. Additionally, the solid sediment output was estimated using the discharge data as well as suspended sediment concentration from several

    Eclogite-facies rocks pertaining to the Penninic realm of the Eastern Alps are exposed as a thin, fault- bounded sliver, juxtaposed against rocks of lower metamorphic grade, within the central Tauern Window, southwest Austria. Previous work suggests that the eclogites formed as a result of southward subduction of the European continental margin beneath the advancing Apulian complex during the Alpine orogeny. The Eclogite Zone itself consists of a diverse metasedimentary pile, dominated by calcareous schists, within which micro- to mega boudins of mafic eclogite are exposed. Peak conditions for both the eclogites and host metasediments are ~ 20 kbar at ~ 600° C. Structurally beneath the Eclogite Zone crystalline Pennine basement and associated cover units form the Venediger Complex, whereas the hanging-wall comprises basement slices (the Rote Wande Nappe) and an in--complete ophiolitic sequence - the Glockner nappe. This work presents results from a revised study of the tectono-metamorphic evolution of the Eclogite Zone and adjacent nappes. New pseudosections for eclogitic pelites show a well-constrained, clockwise P--T path, which culminates in peak conditions within the garnet-chloritoid-kyanite field. X-Ray mapping and REE profiles are employed to link the growth of allanitic epidotes to the rock's P--T evolution. Further pseudosections, which model rocks from both hanging and footwall units provide fresh constraints on the region's P--T evolution. Thermobarometric data are combined with new petrographic and field-based, structural datasets to form the basis of an isotope geochronology study, which aims to resolve conflicting views on the timing of eclogite- facies metamorphism in the Eastern Alps. A better understanding of the region's P--T--t relationship will have important implications for: 1. The geodynamic evolution of the Alpine chain as a whole; namely whether collision occurred contemporaneously along the eastern portion of the belt, and 2. The study of

    Four kaolin deposits in the Bohemian Massif were studied in order to assess the potential for the recovery of rare earth elements (REE) as by-products from the residue after extraction and refining of the raw kaolin. The behaviour of REE + Y during kaolinitization was found to be largely a function of pre-alteration mineralogy. In the examples studied, i.e. granite-derived deposits of Kriechbaum (Austria) and Božičany, and arkose-derived deposits of Kaznějov and Podbořany (all Czech Republic), the REE + Y are predominantly hosted by monazite which has remained unaffected by kaolinitization. The overall REE + Y content of the variably kaolinitized rocks is strongly dependent on their genesis. While ion adsorption plays only a minor role in the concentration of REE + Y in the studied kaolinitized rocks, the processing and refining of the raw kaolin leads to residues that are enriched in REE + Y by a factor of up to 40. The use of a magnetic separator and a hydrocyclone in the processing of the raw material can yield REE + Y contents of as much as 0.77 wt%. Although this value compares well with the REE + Y concentration in some potentially economic REE + Y projects elsewhere, the overall tonnage of the (REE + Y)-enriched residue is by far not sufficient to consider economic extraction of REE + Y as by-product. Our results are most probably applicable also to other kaolin deposits derived from the weathering of Hercynian basement granites elsewhere (e.g. in Saxonia and Bavaria, Germany). Overall, the potential for REE + Y production as by-product from kaolin mining has to be regarded as minimal.

    The compositional characteristics of untreated pure juice prepared from 88 apple varieties grown in the region of Eferding/Upper Austria were determined. Many of the analyzed varieties are noncommercial, old varieties not present in the market. The aim of the study was to quantitate the mineral, phosphate, trace elements, and polyphenolic content in order to identify varieties that are of particular interest for a wider distribution. Great variations among the investigated varieties could be found. This holds especially true for the total polyphenolic content (TPC) ranging from 103.2 to 2,275.6 mg/L. A clear dependence of the antioxidant capacity on the TPC levels was detected. Bioinformatics was employed to find specific interrelationships, such as Mg²⁺/Mn²⁺ and PO₄³⁻/K⁺, between the analyzed bio- and phytochemical parameters. Furthermore, special attention was drawn on putative effects of grafting on the phytochemical composition of apple varieties. By grafting 27 different apple varieties on two trees grown close to each other, it could be shown that the apple fruits remain their characteristic phytochemical composition. Finally, apple juice prepared from selected varieties was further characterized by additional biochemical analysis including cytotoxicity, epidermal growth factor receptor (EGFR) inhibition, and α-amylase activity tests. Cytotoxicity and inhibition of EGFR activation were found to be dependent on the TPC, while α-amylase activity was reduced by the apple juices independent of the presence of polyphenolic substances. Taken together selected apple varieties investigated within this study might serve as preferable sources for the development of apple-based food with a strong focus on health beneficial effects.

    A prospective, noninterventional survey was conducted among Clostridium difficile positive patients identified in the time period of July until October 2012 in 18 hospitals distributed across all nine Austrian provinces. Participating hospitals were asked to send stool samples or isolates from ten successive patients with C.difficile infection to the National Clostridium difficile Reference Laboratory at the Austrian Agency for Health and Food Safety for PCR-ribotyping and in vitro susceptibility testing. A total of 171 eligible patients were identified, including 73 patients with toxin-positive stool specimens and 98 patients from which C. difficile isolates were provided. Of the 159 patients with known age, 127 (74.3%) were 65 years or older, the median age was 76 years (range: 9-97 years), and the male to female ratio 2.2. Among these patients, 73% had health care-associated and 20% community-acquired C. difficile infection (indeterminable 7%). The all-cause, 30-day mortality was 8.8% (15/171). Stool samples yielded 46 different PCR-ribotypes, of which ribotypes 027 (20%), 014 (15.8%), 053 (10.5%), 078 (5.3%), and 002 (4.7%) were the five most prevalent. Ribotype 027 was found only in the provinces Vienna, Burgenland, and Lower Austria. Severe outcome of C. difficile infection was found to be associated with ribotype 053 (prevalence ratio: 3.04; 95% CI: 1.24, 7.44), not with the so-called hypervirulent ribotypes 027 and 078. All 027 and 053 isolates exhibited in vitro resistance against moxifloxacin. Fluoroquinolone use in the health care setting must be considered as a factor favoring the spread of these fluoroquinolone resistant C. difficile clones.

    Deposits spanning the Radotruncana calcarata Taxon Range Zone at the Postalm section, Northern Calcareous Alps (Austria) are examined quantitatively for foraminiferal assemblages, especially the planktonic group. This study focuses on establishing a high resolution record spanning an 800 ka long stratigraphic interval from the active continental margin of the Penninic Ocean. The Postalm section displays reddish limestone- marl alternations representing precession cycles. For this study, 26 samples were taken bed by bed to allow a “per-precession-cycle” resolution (i.e., a minimum sample distance of ∼20 ka). Samples from limestones as well as from marls were examined for foraminiferal assemblages. Data suggest a typical, open marine Campanian foraminiferal community. The >63 µm fraction is dominated by opportunist taxa, i.e., members of Muricohedbergella and biserial planktic foraminifera. Archaeoglobigerina and “Globigerinelloides” appear frequently and benthic foraminifera are very sparsely found. The share of globotruncanids, representing more complex morphotypes amongst planktonic foraminifera, is recorded with 5–10%. The state of preservation of foraminifera from the Postalm section is moderate to poor. Differences between samples from marls and samples from limestone are evident, but do not reveal evidence that there was an influence on the postdepositional microfossil communities. However, data from microfossils showing moderate to bad preservation can still offer valuable insight into the palaeoenvironment and biostratigraphy. Information gathered on the composition of the planktonic foraminiferal assemblage confirms a low-to-mid-latitude setting for the Postalm section. As well resolved records of Late Cretaceous foraminifera assemblages are rare, the examination of the Radotruncana calcarata Taxon Range Zone provides some insights into variations and short term changes during the very short period of 800 ka.

    At present, GNSS monitoring of landslides is an accepted and approved method to detect movements of slopes at risk in the sub-centimetre level. However, high-precision geodetic GNSS-receivers are expensive, therefore this monitoring method is not widely applied. Recently low-cost GNSS-receivers are conquering the geodetic market and are well suited for a cost effective and yet precise GNSS-monitoring. During the project GeoWSN, which was funded by the Austrian Research Promotion Agency (FFG), an applicable low-cost monitoring system was developed at Graz University of Technology. The system is based on a so-called Wireless Sensor Network (WSN) consisting of low-cost GNSS-receivers, temperature and humidity sensors and inertial measurement units. Additionally energy-harvesting technologies and power-saving algorithms provide that the system is energy- autarkic. For real-time applications, a communication link between the sensor nodes is implemented. The relative positioning method RTK (Real Time Kinematic) is applied to reach the highest possible accuracy. The GeoWSN sensor nodes enable the detection of possible movements in the real-time processed positions of the sensor nodes. To ensure a real-time evaluation and interpretation of the data, the current status of the slope can be acquired by a local warning centre. Therefore, affected people can be warned within a short latency. Several test-scenarios have shown the acceptance of the system at the warning centre of Styria, Austria. This contribution should give an overview of the main idea of a low-cost warning system and results of the project GeoWSN.

    Samples from a pristine raised peat bog runoff in Austria, the Tannermoor creek, were analysed for their iron linked to natural organic matter (NOM) content. Dissolved organic carbon < 0.45 μm (DOC) was 41-64 mg L(-1), iron 4.4-5.5 mg L(-1). Samples were analysed applying asymmetric field flow fractionation (AsFlFFF) coupled to UV-vis absorption, fluorescence and inductively coupled plasma mass spectrometry (ICP-MS). The samples showed an iron peak associated with the NOM peak, one sample exhibiting a second peak of iron independent from the NOM peak. As highland peat bogs with similar climatic conditions and vegetation to the Tanner Moor are found throughout the world, including areas adjacent to the sea, we examined the behaviour of NOM and iron in samples brought to euhaline (35‰) conditions with artificial sea salt. The enhanced ionic strength reduced NOM by 53% and iron by 82%. Size exclusion chromatography (SEC) of the samples at sea-like salinity revealed two major fractions of NOM associated with different iron concentrations. The larger one, eluting sharply after the upper exclusion limits of 4000-5000 g mol(-1), seems to be most important for iron chelating. The results outline the global importance of sub-mountainous and mountainous raised peat bogs as a source of iron chelators to the marine environment at sites where such peat bogs release their run-offs into the sea.

    Mosquitoes (Diptera: Culicidae) are important vectors for a wide range of pathogenic organisms. As large parts of the human population in developed countries live in cities, the occurrence of vector-borne diseases in urban areas is of particular interest for epidemiologists and public health authorities. In this study, we investigated the mosquito occurrence in the city of Vienna, Austria, in order to estimate the risk of transmission of mosquito-borne diseases. Mosquitoes were captured using different sampling techniques at 17 sites in the city of Vienna. Species belonging to the Culex pipiens complex (78.8 %) were most abundant, followed by Coquillettidia richiardii (10.2 %), Anopheles plumbeus (5.4 %), Aedes vexans (3.8 %), and Ochlerotatus sticticus (0.7 %). Individuals of the Cx. pipiens complex were found at 80.2 % of the trap sites, while 58.8 % of the trap sites were positive for Cq. richiardii and Ae. vexans. Oc. sticticus was captured at 35.3 % of the sites, and An. plumbeus only at 23.5 % of the trap sites. Cx. pipiens complex is known to be a potent vector and pathogens like West Nile virus (WNV), Usutu virus (USUV), Tahyna virus (TAHV), Sindbis virus (SINV), Plasmodium sp., and Dirofilaria repens can be transmitted by this species. Cq. richiardii is a known vector species for Batai virus (BATV), SINV, TAHV, and WNV, while Ae. vexans can transmit TAHV, USUV, WNV, and Dirofilaria repens. An. plumbeus and Oc. sticticus seem to play only a minor role in the transmission of vector-borne diseases in Vienna. WNV, which is already wide-spread in Europe, is likely to be the highest threat in Vienna as it can be transmitted by several of the most common species, has already been shown to pose a higher risk in cities, and has the possibility to cause severe illness.

    Historic mining in the Eastern Alps has left us with a legacy of numerous spoil heaps hosting specific, metal tolerant vegetation. Such habitats are characterized by elevated concentrations of toxic elements but also by high irradiation, a poorly developed substrate or extreme pH of the soil. This study investigates the distribution of vascular plants, mosses and lichens on a copper spoil heap on the ore bearing Knappenberg formed by Prebichl Layers and Werfener Schist in Lower Austria. It serves as a model for discriminating between various ecological traits and their effects on vegetation. Five distinct clusters were distinguished: (1) The bare, metal rich Central Spoil Heap was only colonised by highly resistant specialists. (2) The Northern and (3) Southern Peripheries contained less copper; the contrasting vegetation was best explained by the different microclimate. (4) A forest over acidic bedrock hosted a vegetation overlapping with the periphery of the spoil heap. (5) A forest over calcareous bedrock was similar to the spoil heap with regard to pH and humus content but hosted a vegetation differing strongly to all other habitats. Among the multiple toxic elements at the spoil heap, only Cu seems to exert a crucial influence on the vegetation pattern. Besides metal concentrations, irradiation, humidity, humus, pH and grain size distribution are important for the establishment of a metal tolerant vegetation. The difference between the species poor Northern and the diverse Southern Periphery can be explained by the microclimate rather than by the substrate. All plant species penetrating from the forest into the periphery of the spoil heap originate from the acidic but not from the calcareous bedrock. PMID:27185350

    Background The prosperity of Hallstatt (Salzkammergut region, Austria) is based on the richness of salt in the surrounding mountains and salt mining, which is documented as far back as 1500 years B.C. Substantial archaeological evidence of Bronze and Iron Age salt mining has been discovered, with a wooden staircase (1108 B.C.) being one of the most impressive and well preserved finds. However, after its discovery, fungal mycelia have been observed on the surface of the staircase, most probably due to airborne contamination after its find. Objective As a basis for the further preservation of this valuable object, the active micro-flora was examined to investigate the presence of potentially biodegradative microorganisms. Results Most of the strains isolated from the staircase showed to be halotolerant and halophilic microorganisms, due to the saline environment of the mine. Results derived from culture-dependent assays revealed a high fungal diversity, including both halotolerant and halophilic fungi, the most dominant strains being members of the genus Phialosimplex (synonym: Aspergillus). Additionally, some typical cellulose degraders, namely Stachybotrys sp. and Cladosporium sp. were detected. Numerous bacterial strains were isolated and identified as members of 12 different genera, most of them being moderately halophilic species. The most dominant isolates affiliated with species of the genera Halovibrio and Marinococcus. Halophilic archaea were also isolated and identified as species of the genera Halococcus and Halorubrum. Molecular analyses complemented the cultivation assays, enabling the identification of some uncultivable archaea of the genera Halolamina, Haloplanus and Halobacterium. Results derived from fungi and bacteria supported those obtained by cultivation methods, exhibiting the same dominant members in the communities. Conclusion The results clearly showed the presence of some cellulose degraders that may become active if the requirements for

    Background Leading scholars in ethnobiology and ethnomedicine continuously stress the need for moving beyond the bare description of local knowledge and to additionally analyse and theorise about the characteristics and dynamics of human interactions with plants and related local knowledge. Analyses of the variation of local knowledge are thereby perceived as minimal standard. In this study we investigate the distribution and variation of wild plant knowledge in five domains: food, drinks, human medicine, veterinary medicine and customs. We assess relations between the wild plant knowledge of informants and their socio-demographic as well as geographic background. Method Research was conducted in the Biosphere Reserve Grosses Walsertal, Austria. Structured questionnaires were used to inquire wild plant knowledge from 433 informants with varying socio-demographic and geographic background. Children assisted in the data collection. Data was analysed using descriptive statistics and generalized linear models. Results and discussion A majority of respondents is familiar with wild plant uses, however to varying degrees. Knowledge variations depend on the socio-demographic and geographic background of the informants as well as on the domains of knowledge under investigation: women, older informants and homegardeners report more human medicinal applications and applications in drinks than men, younger informants and non-homegardeners; farmers know a greater variety of veterinary medicinal applications than non-farmers; the place of residence relates significantly to food and veterinary uses. Customs are difficult to investigate in standardized matrices. The household-related distribution of work and the general socio-cultural context are especially helpful in order to explain intracultural variation of knowledge in the Grosses Walsertal.

    A well-established possibility to treat opiate addiction is the participation in opiate maintenance treatment programmes. For this purpose the opioids methadone and buprenorphine have been evaluated and are used nowadays in many countries. However, since 1998 also the use of slow-release oral morphine (SROM) has been legally permitted in Austria. Our data show that these morphine preparations are frequently abused and are dominating the black market in the meantime. Especially the intravenous consumption of SROM goes along with highly dangerous side effects that exceed the risks of needle sharing alone. Special galenics are supposed to ensure a 24 h effect of the otherwise quickly metabolised morphine. If dissolved and injected, insoluble contents such as talcum cause microembolisms, leading to severe damages of the inner organs. Furthermore, SROM, i.e. a drug prescribed by physicians, has been proved to be the main responsible substance in most drug related deaths since its permission and has nearly replaced heroin. Forensic physicians play a major role in the profound examination of these cases, including extensive toxicological analyses and interpretation of results. For instance, a differentiation between a recent morphine and heroin consumption is certainly possible, provided appropriate methods are used. A reliable estimation of the current situation of drug abusing habits is a premise for adequate therapeutic offers and preventive measures. Thus, well-founded and comparable data have to be collected. To facilitate data report a standardized report form has been developed that includes an obligatory statement regarding morphine or heroin consumption. This should help to enlighten the ongoing discussion on the role of SRM in drug abuse cases.

    Tick-borne encephalitis (TBE) was until the early 1980s among the most frequent causes of viral induced central-nervous infectious diseases in Austria. Since 1981 the vaccination was forced by intensive media campaigns. Aim of this study was to investigate the effects of the media campaigns and to evaluate them under health economic criteria. The number of hospitalized TBE-cases declines from 1981 to 1990, the linear trend shows a reduction from 427 to 109. If the linear trend from 1971 to 1980 would have continued the respective number in 1990 would have been 585 cases. Thus the model shows that from 1981 to 1990 more than 50% or 2,690 out of 5,368 possible cases are prohibited, from 1991 to 2000 based on the 1990 vaccination rate approximately 85% or 500 cases annually. In the age group 7 to 14 years the proportion of protected exposed is almost 97%. The loss of quality of life is higher than represented by the inpatient statistics. Many of the TBE victims have chronic impairments, mainly due to paresis and depression. Based on the 1990 cost data economic benefits for the social insurance companies in the decade 1981 to 1990 are AS 147 millions for inpatient care, respectively AS 108 millions for loss of productivity and AS 77 millions for early retirement, resulting in total benefits of AS 331 millions. The estimated benefits for 1991 to 2000 based on 1990 cost data are AS 270 millions for inpatient care, AS 200 millions for loss of productivity, and AS 368 for early retirement (total AS 828 millions).

    Identifying Bacillus cereus as the causative agent of a foodborne outbreak still poses a challenge. We report on the epidemiological and microbiological investigation of three outbreaks of food poisoning (A, B, and C) in Austria in 2013. A total of 44% among 32 hotel guests (A), 22% among 63 employees (B) and 29% among 362 residents of a rehab clinic (C) fell sick immediately after meal consumption. B. cereus isolated from left overs or retained samples from related foods were characterized by toxin gene profiling, and molecular typing using panC sequencing and M13-PCR typing (in outbreak A and C). We identified two B. cereus strains in outbreak A, and six B. cereus strains, each in outbreak B and C; we also found Staphylococcus aureus and staphylococcal enterotoxins in outbreak A. The panC sequence based phylogenetic affiliation of the B. cereus strains, together with findings of the retrospective cohort analyses, helped determining their etiological role. Consumption of a mashed potatoes dish in outbreak A (RR: ∞), a pancake strips soup in outbreak B (RR 13.0; 95% CI 1.8-93.0) and for outbreak C of a fruit salad (RR 1.50; 95% CI 1.09-2.00), deer ragout (RR: 1.99; 95% CI 1.23-3.22) and a cranberry/pear (RR 2.46; 95% CI 1.50-4.03)were associated with increased risk of falling sick. An enterotoxigenic strain affiliated to the phylogenetic group with the highest risk of food poisoning was isolated from the crème spinach and the strawberry buttermilk, and also from the stool samples of the one B. cereus positive outbreak case-patient, who ate both. Our investigation of three food poisoning outbreaks illustrates the added value of a combined approach by using epidemiological, microbiological and genotyping methods in identifying the likely outbreak sources and the etiological B. cereus strains.

    Schmallenberg virus (SBV) has emerged in summer-autumn 2011 in north-western Europe. Since then, SBV has been continuously spreading over Europe, including Austria, where antibodies to SBV, as well as SBV genome, were first detected in autumn 2012. This study was performed to demonstrate the dynamics of SBV spread within Austria, after its probable first introduction in summer 2012. True seroprevalence estimates for cattle and small ruminates were calculated to demonstrate temporal and regional differences of infection. Furthermore, the probability of SBV genome detection in foetal tissues of aborted or stillborn cattle and small ruminants as well as in allantoic fluid samples from cows with early foetal losses was retrospectively assessed. SBV first reached Austria most likely in July-August 2012, as indicated by retrospective detection of SBV antibodies and SBV genome in archived samples. From August to October 2012, a rapid increase in seroprevalence to over 98% in cattle and a contemporaneous peak in the detection of SBV genome in foetal tissues and allantoic fluid samples was noted, indicating widespread acute infections. Notably, foetal malformations were absent in RT-qPCR positive foetuses at this time of the epidemic. SBV spread within Austrian cattle reached a plateau phase as early as October 2012, without significant regional differences in SBV seroprevalence (98.4-100%). Estimated true seroprevalences among small ruminates were comparatively lower than in cattle and regionally different (58.3-95.6% in October 2012), potentially indicating an eastward spread of the infection, as well as different infection dynamics between cattle and small ruminants. Additionally, the probability of SBV genome detection over time differed significantly between small ruminant and cattle samples subjected to RT-qPCR testing.

    This paper presents a new approach for incorporating public hospitals by contrasting the experience from an "old" EU country (Austria) with a new EU member state (Estonia). In the EU (including the new member states) hospital overcapacity is a serious problem, from a technical, fiscal and political perspective. Few countries have succeeded in establishing an appropriate framework for resource management and for guaranteeing long-term financial viability of their hospital network. Many countries are in search of effective policies for improved hospital management and more cost-effective resource use in the health sector. Over the past decade, experiences in Austria and Estonia have emerged as innovative examples which may provide lessons for other EU countries and beyond. This paper describes the evolution of public hospitals from public budgetary units and public management to incorporated autonomous organizations under private corporate law, resulting in a contractual relationship between (public) owners and private hospital management. Outdated and inefficient public sector structures were replaced by more agile corporate management. The arrangement allows for investments, operating costs and budgeting according to strategic business goals as opposed to political "fiat". Shielding hospitals from local political influence is an important aspect of this concept. Horizontal integration through networking of public hospitals and introducing private management helps create a new corporate culture, allowing for more flexibility to achieve efficiencies through downsizing and economies of scale. Based on contracts the new balance between ownership and managerial functions create strong incentives for a more business-like, results-oriented and consumer-friendly management. This was achieved both in Austria and Estonia in a politically sensitive way, adopting a long-term vision and by protecting the interests of hospital owners and staff. PMID:16919838

    Tropospheric ozone is an important air pollutant, although plants have active defense strategies (e.g. antioxidants), the cumulative ozone dose may lead to chronic damages to plant tissues. Ozone enters into plants through stomata and reacts with other chemicals to create toxic compounds. This affects plant photosynthesis and may reduce CO2 fixation, and consequently growth. Open top cambers (OTC) are usually used to study the effects of elevated ozone levels on photosynthesis; whereas field studies with on site occurring ozone levels are rare. A recent modelling study on Norway spruce stands in Austria exhibited trends in model errors indicating that an increase in ozone dose leads to a reduction in volume increment. This study aims to explore how different ozone doses affect photosynthesis under field conditions and may translate into growth response for 12 stands of Norway spruce, distributed along an ozone concentration gradient across Austria. A LI-6400xt photosynthesis system was utilized to collect physiological parameters including net photosynthesis, stomata conductance, internal CO2 concentration, transpiration, etc. Chlorophyll fluorescence data was collected by using a PEA chlorophyll fluorescence meter, and chlorophyll content was measured. Morphological characteristics and soil samples were also analyzed. Ozone dose to leaf tissue was calculated from external ozone concentration, the conductance of the stomata to ozone, the leaf area index and the time span of the day when ozone uptake takes place. Our results confirm that increasing cumulative ozone dose reduces maximum assimilation rate and carboxylation efficiency under field conditions. Our final goal is to quantify how far this ozone induced reduction in assimilation power ultimately translates into a growth reduction of Norway spruce in Austria.

    Results from a previous project "FarmClim" highlight that the IPCC default emission factor is not able to reflect region specific N2O emissions from Austrian arable soils. The methodology is limited in identifying hot spots and hot moments of N2O emissions. When estimations are based on default emission factors no recommendations can be given on optimisation measures that would lead to a reduction of soil N2O emissions. The better the knowledge is about Nitrogen and Carbon budgets in Austrian agricultural managed soils the better the situation can be reflected in the Austrian GHG emission inventory calculations. Therefore national and regionally modelled emission factors should improve the evidence for national deviation from the IPCC default emission factors and reduce the uncertainties. The overall aim of NitroAustria is to identify the drivers for N2O emissions on a regional basis taking different soil types, climate, and agricultural management into account. We use the LandscapeDNDC model to update the N2O emission factors for N fertilizer and animal manure applied to soils. Key regions in Austria were selected and region specific N2O emissions calculated. The model runs at sub-daily time steps and uses data such as maximum and minimum air temperature, precipitation, radiation, and wind speed as meteorological drivers. Further input data are used to reflect agricultural management practices, e.g., planting/harvesting, tillage, fertilizer application, irrigation and information on soil and vegetation properties for site characterization and model initialization. While at site scale, arable management data (crop cultivation, rotations, timings etc.) is obtained by experimental data from field trials or observations, at regional scale such data need to be generated using region specific proxy data such as land use and management statistics, crop cultivations and yields, crop rotations, fertilizer sales, manure resulting from livestock units etc. The farming

    Kettle holes are very common features in proglacial environments. Myriads of small, often circular shaped lakes are indicative of dead ice slowly melting out after the collapse of glaciers and subsequent burial of glaciofluvial sediments. Many of these lakes transformed into mires during the Postglacial and the Holocene. Still, little is known about the mechanisms leading to mire formation in such environments. We aim to analyse the shape and the postglacial history of infilling and peat accumulation of a typical dead ice kettle using 2D resistivity surveying, core-drilling, 14C dating and palynologic analyses. The kettle hole mire is located within a small kame delta deposit just south of the LGM extend of the Salzach Piedmont glacier (Austria/Germany). Today, the mire is a spot of exceptional high biodiversity and under protection. Sediment core samples extracted in the deepest (c. 10-14 m) and central part of the kettle directly overly lacustrine fine sediments and yielded young ages covering the subatlantic period only. Young ages are in agreement with palynologic results comprising e.g. pollen of secale (rye) and juglans (walnut). However, these deposits are situated beneath a massive water body (10 m), only covered by a thin floating mat. A second, more distally situated drill core indicates the thinning of this water body at the expense of peat deposits covering the Late Glacial to Middle Holocene. Multiple 2D resistivity data support drilling information and enabled us to reconstruct the shape of the basin. The transition from lacustrine sediments to the water body above is characterised by a sharp increase in resistivity. Furthermore, the resistivity pattern within the entire kettle indicates an increase towards the centre, most probably as a result of the changing nutrient content. The postglacial evolution of the mire is in agreement with the concept of "floating mat terrestrialisation", representing a horizontal growth of the floating mat from the edges

    Longer data series (e.g. >10 a) of ground temperatures in alpine regions are helpful to improve the understanding regarding the effects of present climate change on distribution and thermal characteristics of seasonal frost- and permafrost-affected areas. Beginning in 2004 - and more intensively since 2006 - a permafrost and seasonal frost monitoring network was established in Central and Eastern Austria by the University of Graz. This network consists of c.60 ground temperature (surface and near-surface) monitoring sites which are located at 1922-3002 m a.s.l., at latitude 46°55'-47°22'N and at longitude 12°44'-14°41'E. These data allow conclusions about general ground thermal conditions, potential permafrost occurrence, trend during the observation period, and regional pattern of changes. Calculations and analyses of several different temperature-related parameters were accomplished. At an annual scale a region-wide statistical significant warming during the observation period was revealed by e.g. an increase in mean annual temperature values (mean, maximum) or the significant lowering of the surface frost number (F+). At a seasonal scale no significant trend of any temperature-related parameter was in most cases revealed for spring (MAM) and autumn (SON). Winter (DJF) shows only a weak warming. In contrast, the summer (JJA) season reveals in general a significant warming as confirmed by several different temperature-related parameters such as e.g. mean seasonal temperature, number of thawing degree days, number of freezing degree days, or days without night frost. On a monthly basis August shows the statistically most robust and strongest warming of all months, although regional differences occur. Despite the fact that the general ground temperature warming during the last decade is confirmed by the field data in the study region, complications in trend analyses arise by temperature anomalies (e.g. warm winter 2006/07) or substantial variations in the winter

    By now there is a broad consensus that due to human-induced global change the frequency and magnitude of heavy precipitation events is expected to increase in certain parts of the world. Given the fact, that rainfall serves as the most common triggering agent for landslide initiation, also an increased landside activity can be expected there. Landslide occurrence is a globally spread phenomenon that clearly needs to be handled. The present and well known problems in modelling landslide susceptibility and hazard give uncertain results in the prediction. This includes the lack of a universal applicable modelling solution for adequately assessing landslide susceptibility (which can be seen as the relative indication of the spatial probability of landslide initiation). Generally speaking, there are three major approaches for performing landslide susceptibility analysis: heuristic, statistical and deterministic models, all with different assumptions, its distinctive data requirements and differently interpretable outcomes. Still, detailed comparison of resulting landslide susceptibility maps are rare. In this presentation, the susceptibility modelling outputs of a deterministic model (Stability INdex MAPping - SINMAP) and a statistical modelling approach (generalized additive model - GAM) are compared. SINMAP is an infinite slope stability model which requires parameterization of soil mechanical parameters. Modelling with the generalized additive model, which represents a non-linear extension of a generalized linear model, requires a high quality landslide inventory that serves as the dependent variable in the statistical approach. Both methods rely on topographical data derived from the DTM. The comparison has been carried out in a study area located in the district of Waidhofen/Ybbs in Lower Austria. For the whole district (ca. 132 km²), 1063 landslides have been mapped and partially used within the analysis and the validation of the model outputs. The respective

    Based on an N-S-oriented crustal-scale cross section running east of the Rhine Valley in Vorarlberg, western Austria, we address the Alpine nappe stack and discuss the boundary between Central and Eastern Alps. For our cross section, we used surface geology, drillings and reinterpreted seismic lines, together with published sections. The general architecture of the examined area can be described as a typical foreland fold-and-thrust belt, comprising the tectonic units of the Subalpine Molasse, (Ultra-)Helvetic, Penninic and Austroalpine nappes. These units overthrusted the autochthonous Molasse along the south-dipping listric Alpine basal thrust. The European Basement, together with its autochthonous cover, dips gently towards the south and is dissected by normal faults and trough structures. The seismic data clearly show an offset not only of the top of the European Basement, but also of the Mesozoic cover and the Lower Marine Molasse. This indicates an activity of the structures as normal faults after the sedimentation of the Lower Marine Molasse. The Subalpine Molasse is multiply stacked, forming a triangle zone at the boundary with the foreland Molasse. The shortening within the Subalpine Molasse amounts to approximately 45 km (~67 %), as deduced from our cross section with the Lower Marine Molasse as a reference. The hinterland-dipping duplex structure of the Helvetic nappes is deduced from surface and borehole data. There are at least two Helvetic nappes needed to fill the available space between the Molasse below and the Northpenninic above. This is in line with the westerly located NRP20-East transect (Schmid et al., Tectonics 15(5):1047-1048, 1996; Schmid et al., The TRANSMED Atlas: the Mediterranean Region from Crust to Mantle, 2004), where the two Helvetic nappes are separated by the Säntis thrust. Yet in contrast to the Helvetic nappes in the NRP20-East transect, both of our Helvetic nappes comprise Cretaceous and Jurassic strata. This change is

    The Heumoes landslide, is located in the eastern Vorarlberg Alps, Austria, 10 km southeast of Dornbirn. The extension of the landslide is about 2000 m in west to east direction and about 500 m at its widest extent in north to south direction. It occurs between an elevation of 940 m in the east and 1360 m in the west, slope angles of more than 60 % can be observed as well as almost flat areas. Its total volume is estimated to be 9.400.000 cubic meters and its average velocities amount to some centimeter per year. Surface signatures or 'photolineations' of creeping landslides, e.g. fractures and rupture lines in sediments and street pavings, and vegetation contrasts by changes of water table in shallow vegetation in principle can be resolved by remote sensing. The necessary ground cell resolution of few centimeters, however, generally can't be achieved by routine areal or satellite imagery. The fast technological progress of unmanned areal vehicles (UAV) and the reduced payload by miniaturized optical cameras now allow for UAV remote sensing applications that are below the high financial limits of military intelligence. Even with 'low-cost' equipment, the necessary centimeter-scale ground cell resolution can be achieved by adapting the flight altitude to some ten to one hundred meters. Operated by scientists experienced in remote-control flight models, UAV remote sensing can now be performed routinely, and campaign-wise after any significant event of, e.g., heavy rainfall, or partial mudflow. We have investigated a concept of UAV-borne remote sensing based on motorized gliders, and four-propeller helicopters or 'quad-rotors'. Several missions were flown over the Heumoes landslide. Between 2006 and 2008 three series UAV-borne photographs of the Heumoes landslide were taken and could be combined to orto-mosaics of the slope area within few centimeters ground cell resolution. We will present the concept of our low cost quad-rotor UAV system and first results of the

    In the context of Lateglacial and Holocene climate change research, rock glaciers (creeping mountain permafrost) also play an important role. They are phenomena of discontinuous alpine permafrost and as such good indicators for the mean annual air temperature for the period they are active. We have 10Be surface exposure dated boulders from two relict rock glaciers in Larstigtal, Austria. This is the type area for a postulated mid-Holocene cold period called the Larstig oscillation. The period of activity was suggested to be of similar age as the mid-Holocene Frosnitz advance of glaciers in the Venediger Mountains farther to the east (Patzelt and Bortenschlager, 1973). For rock glaciers of this size to be active at 2200 m a.s.l. in Larstig valley would have required a significant drop in temperatures, thus a marked mid-Holocene cold pulse, for at least several centuries at around 7.0 ka. In contrast, our exposure dates show that the rock glaciers stabilized during the early Preboreal (Ivy-Ochs et al., submitted). We see no distinct pattern with respect to exposure age and boulder location on the rock glaciers. This implies that for our site the blocks did not acquire inherited 10Be during exposure in the free rock face, in the talus at the base of the slope, or during transport on the rock glaciers. Our data point to final stabilization of the Larstigtal rock glaciers in the earliest Holocene and not in the middle Holocene. Combined with data from other archives (Nicolussi et al., 2005), there appears to have been no time window in the middle Holocene long enough for rock glaciers of the size and at the elevation of the Larstig site to have formed.

    Wetland ecosystems provide multiple functions and services for the well-being of humans. In urban environments, planning and decision making about wetland restoration inevitably involves conflicting objectives, trade-offs, uncertainties and conflicting value judgments. This study applied trade-off and multi criteria decision analysis to analyze and quantify the explicit trade-offs between the stakeholder's objectives related to management options for the restoration of an urban floodplain, the Lobau, in Vienna, Austria. The Lobau has been disconnected from the main channel of the Danube River through flood protection schemes 130 years ago that have reduced the hydraulic exchange processes. Urban expansion has also changed the adjacent areas and led to increased numbers of visitors, which hampers the maximum potential for ecosystem development and exerts additional pressure on the sensitive habitats in the national park area. The study showed that increased hydraulic connectivity would benefit several stakeholders that preferred the ecological development of the floodplain habitats. However, multiple uses including fishery, agriculture and recreation, exploring the maximum potential in line with national park regulations, were also possible under the increased hydraulic connectivity options. The largest trade-offs were quantified to be at 0.50 score between the ecological condition of the aquatic habitats and the drinking water production and 0.49 score between the ecological condition of the terrestrial habitats and the drinking water production. At this point, the drinking water production was traded-off with 0.40 score, while the ecological condition of the aquatic habitats and the ecological condition of the terrestrial habitats were traded off with 0.30 and 0.23 score, respectively. The majority of the stakeholders involved preferred the management options that increased the hydraulic connectivity compared with the current situation which was not preferred by

    The results of streamflow trend studies are often characterised by mostly insignificant trends. This applies especially for trends of annually averaged runoff: In our study region, Western Austria, we found that there is a trend gradient from high-altitude to low-altitude stations, i.e. a pattern of mostly positive annual trends at higher stations and negative ones at lower stations. At mid-altitudes, trends are mostly insignificant. The trends were most probably caused by the following two main processes: On the one hand, melting glaciers produce excess runoff at high-altitude watersheds. On the other hand, increasing evapotranspiration results in decreasing trends at low-altitude watersheds. However, these patterns are masked at mid-altitudes because the resulting positive and negative trends balance each other. To verify these theories, we attributed the detected trends to specific causes. For this purpose, we analysed trends on a daily basis, as the causes for these changes might be restricted to a smaller temporal scale than the annual one. The daily trends were assessed by calculating 30-day moving average subsets and then estimating significance and magnitude. This allowed for the explicit pointing out of the exact days of year (DOY) when certain streamflow trends emerge and then relating them to the according DOYs of trends and annual cycles of other observed variables, e.g. the DOYs when snow height trends occur or the DOY when temperature crosses the freezing point in spring. Concerning trends caused by increased glacial melt, we applied correlation analyses between glacier area and trend magnitudes during the corresponding DOYs. As a result, the positive trends in spring were attributed to an earlier and more intense snow melt. The ones that follow in late spring at upper stations could be related to increased glacial melt. The negative trends in summertime that turn up earlier at low-altitude stations and later at high-altitude stations are most

    We investigate the geological and geotechnical characteristics of the Ludoialm Landslide (Tyrol, Austria), a very slow to extremely slow clay, silt rotational slide located in the Northern Calcareous Alps. With a length of 700 m and a maximum width of 300 m the landslide involves at least 500,000 m³ of till and debris flow deposits. Given that the Ludoialm Landslide occurs in a relatively flat terrain with an average slope angle of 17°, a particular geotechnical and hydrogeological situation is assumed. This study focuses on processes and mechanisms which have triggered the soil slide. Several methods are applied to gain an integral understanding of the landslide including the analysis of historic documents and aerial views, geomorphological and geological field mapping, laboratory analysis of geotechnical parameters and clay mineralogy, numerical modelling and remote sensing. The Ludoialm Landslide dates back at least to the time of the oldest campaign of aerial imagery in this area in 1952. However it can be assumed that the initial formation of the landslide is much older. Digital photogrammetry is applied to derive a sequence of terrain models from stereo pairs of historic aerial views. These terrain models are then used to simulate the deformation history of the landslide during the last decades. In the last sixty years, the landslide area has extended notably and was reactivated twice in 1967 and 1999 as a result of intensive snow melting in spring. Detailed field mapping showed that the landslide consists of several slabs of variable activity and secondary slides at the toe. In order to improve the understanding of the geotechnical and hydrogeological characteristics of the landslide, samples for laboratory analyses were collected from the till and debris flow deposits as well as from the underlying marl. On the one hand, a mineral analysis using X-ray diffraction was performed whereas on the other hand, drained and undrained triaxial tests were conducted

    Climate-induced environmental changes are triggering the dynamic evolution of high-mountain lakes worldwide, a phenomenon that has to be monitored in terms of lake outburst hazards. We analyzed the spatial distribution and recent temporal development of high-mountain lakes in a study area of 6139 km2, covering the central European Alps over most of the province of Tyrol and part of the province of Salzburg in western Austria. We identified 1024 natural lakes. While eight lakes are ice-dammed, one-third of all lakes are located in the immediate vicinity of recent glacier tongues, half of them impounded by moraines, half by bedrock. Two-thirds of all lakes are apparently related to LIA or earlier glaciations. One landslide-dammed lake was identified in the study area. The evolution of nine selected (pro)glacial lakes was analyzed in detail, using multitemporal remotely sensed images and field reconnaissance. Considerable glacier retreat led to significant lake growth at four localities, two lakes experienced stagnant or slightly negative areal trends, one lake experienced a more significant negative areal trend, and two lakes drained completely during the investigation period. We further (i) analyzed the susceptibility of selected lakes to glacial lake outburst floods (GLOFs), using two different methods; (ii) identified potential triggers and mechanisms of GLOFs; (iii) calculated possible flood magnitudes for predefined flood scenarios for a subset of the lakes; and (iv) delineated potentially impacted areas. We distinguished three phases of development of bedrock-dammed lakes: (a) a proglacial, (b) a glacier-detached, and (c) a nonglacial phase. The dynamics - and also the susceptibility of a lake to GLOFs - decrease substantially from (a) to (c). Lakes in the stages (a) and (b) are less prominent in our study area, compared to other glacierized high-mountain regions, leading us to the conclusion that (i) the current threat to the population by GLOFs is lower but

    Investigating fossil landslides may help to predict possible future events. The larger than 3 km2 Köfels rockslide, located in the Ötztal Valley (Tyrol, Austria) represents one of the largest landslides in metamorphic rock masses in the Alps. It occurred in the early Holocene approx. 8700 years BP and has been subject of numerous studies. So far no reconstruction of the pre-failure topography and volume determination based on high resolution airborne laser scanning digital elevation models (DEM) and up-to-date GIS methods was done. In addition, only a few numerical studies using numerical modelling techniques focusing on the failure as well as deformation process and the rock mass strength properties were performed. The present work will attempt to close this gap. The Köfels rockslide is reanalyzed with regard to its actual and initial topography as well as the involved failure and deposition volumes based on a recent DEM. The complex topographic situation of the study site requires four different models of the terrain in order to calculate the volume of the failure and deposition mass. Therefore the following topographies are reconstructed: (i) the pre-failure topography representing the situation before the event, (ii) the topography of the failure surface without the deposition mass in the valley, (iii) the topography after the event but before valley incision and deposition of the alluvium north and south of the rock slide deposit, and (iv) the up-to-date DEM, which represents the present topographic situations in the area. The volumes of the failure and deposition masses of the Köfels rock slide are estimated by comparing the four terrain models. Besides geomorphological considerations based on the DEM, published data from boreholes and an investigation adit are used to reconstruct the pre-failure valley topography. For the geotechnical analysis the 2-D discrete element code UDEC by Itasca is applied to a geological cross section of the Köfels rock slide

    Background Changing lifestyles have recently caused a severe reduction of the gathering of wild food plants. Knowledge about wild food plants and the local environment becomes lost when plants are no longer gathered. In Central Europe popular scientific publications have tried to counter this trend. However, detailed and systematic scientific investigations in distinct regions are needed to understand and preserve wild food uses. This study aims to contribute to these investigations. Methods Research was conducted in the hill country east of Graz, Styria, in Austria. Fifteen farmers, most using organic methods, were interviewed in two distinct field research periods between July and November 2008. Data gathering was realized through freelisting and subsequent semi-structured interviews. The culinary use value (CUV) was developed to quantify the culinary importance of plant species. Hierarchical cluster analysis was performed on gathering and use variables to identify culture-specific logical entities of plants. The study presented was conducted within the framework of the master's thesis about wild plant gathering of the first author. Solely data on gathered wild food species is presented here. Results Thirty-nine wild food plant and mushroom species were identified as being gathered, whereas 11 species were mentioned by at least 40 percent of the respondents. Fruits and mushrooms are listed frequently, while wild leafy vegetables are gathered rarely. Wild foods are mainly eaten boiled, fried or raw. Three main clusters of wild gathered food species were identified: leaves (used in salads and soups), mushrooms (used in diverse ways) and fruits (eaten raw, with milk (products) or as a jam). Conclusions Knowledge about gathering and use of some wild food species is common among farmers in the hill country east of Graz. However, most uses are known by few farmers only. The CUV facilitates the evaluation of the culinary importance of species and makes comparisons

    The alien plant species Fallopia japonica (Japanese Knotweed), Fallopia sachalinensis (Sakhalin Knotweed) and the clonal knotweed hybrid Fallopia × bohemica are invasive plant species which spread out within Europe. They often form dense stands along Rivers and have negative impacts on biodiversity and ecosystem functioning and also threaten the stability of river banks. Due to their life form, vitality and their enormous ability to regenerate themselves, they are extremely hard to fight. The control measurements against Fallopia species are therefore complicated and often do not have the desired results. Our research tried two approaches to deal with these invasive plant species. The first approach was the use of soil bioengineering techniques which have considerable potential for the management of Fallopia. In our study at the river Schwechat (Lower Austria) we tested two soil bioengineering methods for the control of Fallopia. The first method was the use of living brush mattresses with willows (Salix sp.) to fight the growth of Fallopia species. Within a second method a black liner was used in combination with willow cuttings. After cutting the Fallopia stands the liner was applied to the river bank and fixed with living willow cutting to the surface. The two areas were compared to untreated river bank areas. At several points of time we compared the aboveground response (number of shoots, basal shoot diameters, plant heights, number of stems, aboveground biomass). Additionally the aboveground plant parameters of the willows were measured. In a second approach it was tested if Fallopia can be suppressed or even exterminated if they are submerged for longer time periods. For the experiments Fallopia rhizomes were planted in plastic containers. After a certain growing period, the plants were cut and documented quantitatively by the measurements of shoot lengths, shoot diameters and aboveground biomass. After the first harvest the containers were flooded with

    Fault zones are the result of tectonic processes and are geometrical features frequently encountered in carbonate aquifer systems. They can hamper the fluid migration (hydrogeological barriers), propagate the movement of fluid (draining conduits) or be a combination of both processes. Numerical modelling of fractured carbonate aquifer systems is strongly bound on the knowledge of a profound conceptual model including geological and tectonic settings such as fault zones. In further consequence, numerical models can be used to evaluate the conceptual model and its introduced approximations. The study was conducted in a fractured carbonate aquifer built up by permomesozoic dolo/limestones of the Semmering-Wechsel complex in the Eastern Alps (Austria). The aquifer has an assumed thickness of about 200 m and dips to the north. It is covered by a thin quartzite layer and a very low permeable layer of quartz-phyllite having a thickness of up to several hundred meters. The carbonate layer crops out only in the southern part of the investigation area, where it receives autogenic recharge. The geological complexity affects some uncertainties related to the extent of the model area, which was determined to be about 15 km². Three vertical fault zones cross the area approximately in a N-S direction. The test site includes an infrastructural pilot tunnel gallery of 4.3 km length with two pumping stations, respectively active since August 1997 and June 1998. The total pumping rate is about 90 l/s and the drawdown data were analysed analytically, providing a hydraulic conductivity of about 5E-05 m/s for the carbonate layer. About 120 m drawdown between the initial situation and situation with pumping is reported by piezometers. This led to the drying up of one spring located at the southern border of the carbonates. A continuum approach using MODFLOW-2005 was applied to reproduce numerically the observed aquifer behaviour and investigate the impact of the three fault zones. First

    The Hirlatz Cave lies in the Dachstein Massif about 2 km SW of Hallstatt, in the Upper Austrian Salzkammergut. With a length of 101 km, this karst cave, located in the Dachstein nappe (Northern Calcareous Alps), is the second largest known cave system in Austria. Within the cave, in the so-called Lehmklamm, located 2.8 km southeast of the cave entrance, laminated (mm-scale) Quaternary clay-sized sediments with interbedded fine-grained sandy layers are preserved. In these layers, numerous soft sediment deformation structures are preserved in many layers. The unconsolidated sediments show rhythmic layering of brighter, carbonate and quartz rich, and darker, more clay mineral rich horizontal varve-like layers, that are assumed to be fluvio-lacustrine deposits. The present study focuses on a very detailed documentation of an approximately 6.8 x 3 m vertical outcrop that was cut by a small brook. Centimeter to millimeter sized water escape structures (intruded cusps and flame structures), folds (detachment folds, fault bend folds) and faults (normal faults, fault propagation folds, bookshelf faults) are described. Because of the geometric analogy to seismogenic structures which have been described at two orders of magnitude larger scales from areas close to the Dead Sea Fault, we suggest that the formation of the investigated soft-sediment structures was also triggered by seismic events. The structures were mainly formed by three different mechanism: (i) North directed gravitational gliding near the sediment surface; (ii) Liquefaction resulting in a density discontinuity and decreasing in shear strength within in the stratified layers; (iii) Extensional faulting that cut through the stratified layers. Observations of coarsening upwards into sandy layers on the top of the outcrop and current ripple indicate a north-directed flow under phreatic conditions, which is opposite to the present flow direction of the vadose water in the cave. The fact that deformation and

    A N-S oriented crustal-scale cross-section was constructed east of the Rhine valley in Vorarlberg, western Austria addressing the central Alps-eastern Alps boundary. The construction was based on published data, surface geology, drillings, as well as on reinterpreted seismic lines. The general architecture of the examined area can be described as a typical foreland fold-and-thrust belt, comprising the tectonic units of the Subalpine Molasse, (Ultra-)Helvetic, Penninic, and Austroalpine nappes. These units overthrusted the autochthonous Molasse along the south-dipping listric Alpine basal thrust. The thermotectonic evolution of this nappe stack is adressed by Bertrand et al. (this session). The Subalpine Molasse is multiply stacked, forming a triangle-zone (Müller et al. 1984). The shortening within the Subalpine Molasse in the cross section has been calculated using the Lower Marine Molasse as a reference and amounts to approx. 46 km, (~70%). Towards east the shortening within the Subalpine Molasse decreases dramatically as shown by Ortner et al. (this session). A well-defined seismic feature in the research area is the European basement together with its autochthonous cover, with a moderate southward dip from about 3500m BSL to approx. 6500m BSL along the ca. 50km long section. Several seismic sections show fault structures offsetting the top of the European basement as well as autochthonous cover. Another discontinuous double reflector that can be identified in several seismic sections is interpreted as the base of the Helvetic nappe complex (approx. at 5000m BSL in the southernmost parts). The internal structure of the Helvetic nappe stack could hardly be resolved. The assumed hinterland dipping duplex-structure of the Helvetic nappes results from surface and borehole-data. However, there are at least two Helvetic nappes needed to fill the available space. The deeper one, termed "Hohenemse nappe" (Wyssling, 1985), is overlain by the superficially exposed

    The 4.4 km-long Hermannshöhle (located in Kirchberg/Wechsel, Lower Austria) is one of the largest caves in the Lower Austroalpine Unit. It is developed in an isolated block of carbonate marble, taking up only 140 x 160 m of ground area and 73 m of elevation difference. The cave is unusual in two respects: (a) its dense network of corridors is arranged in a three-dimensional maze and (b) the most outstanding macro- and micromorphologic features were caused by paragenesis. Speleothems are abundant throughout the cave comprising flowstones, dripstones, helictites, popcorn, calcite rafts, a shield, and moonmilk. Even though most passages are canyon-shaped, the cave shows exclusively phreatic features. Sediment fills are abundant as well, mostly covering the floor of passages to an unknown depth, containing mainly allochthonous material, i.e. schists and gneisses. Besides some vadose dripwater the cave is dry today. A conspicuous feature is the lack of a single water path and instead a maze with multiple flow paths formed. Another interesting feature is that one part of the cave developed below the nearby Ramsbach brook but is still dry. There are small ponors reported from the Ramsbach brook (which were observed during river regulation) indicating an actively draining karst system, which is not yet explored. The aim of this study was to enlighten the palaeohydrology of this cave using morphological and sedimentological observations as well as U/Th dating of speleothems. First results show that the palaeo-environment and the hydrologic setting of the Hermannshöhle were drastically different from today. Undersaturated water sourced from nearby non-karstic gneisses and schists gave rise to well-developed contact karst features. Surprisingly the palaeo flow direction deduced from indicators like scallops and sediment structures was opposite to the flow direction of the present nearby brooks (Rams- and Feistrizbach). Following pulses of clastic sediment input a distinct

    Inland surface waters and associated wetlands must not be neglected when global greenhouse gas emissions are balanced. Natural lakes, rivers and hydroelectric reservoirs are parts of the surface water system where outgassing of CO2 or CH4 enhances the carbon flux to the atmosphere. For lakes, the carbon emission estimates vary over several orders of magnitude, depending on the age of the lake, depth, area, volume, temperature, input of organic carbon and residence time. Nitrogen input into lakes may be caused by wet atmospheric deposition, by surface runoff from agricultural areas and by wastewater inputs into the tributaries. In most cases, denitrification of nitrate is the dominating source of N2O; only in the case of high ammonium loads and oxygen availability nitrification and subsequent denitrification to N2O and N2 play a major role. Focusing on Lake Neusiedl (Austria) as case study, this study aims at illuminating the regional role of a shallow steppe lake as greenhouse gas emitter and at analyzing the local physico-chemical conditions affecting the emission of CO2, CH4 and N2O. The uniqueness of this lake with regard to its shallowness, salinity and sediment depth required the performance of separate measurement campaigns instead of applying general lake greenhouse gas flux rates. For the period of 9 months (based on 6 observation episodes in spring, summer, and autumn), the greenhouse gas emissions of the lake consisted of about 75700 t CO2, 1006 t CH4, and 18 t N2O. Presumably because of significant sulphate concentrations in the lake water (0.3-0.4 g/l) and high pH (8.5-9) the C emissions were not dominated by CH4 but by CO2. Approximately one third of the methane and carbon dioxide emissions originated in the pelagic zone and two thirds in the reed belt whereas nitrous oxide emissions were similar in these two zones. An estimate of ebullitive emissions resulted in additional 1765 t CH4 that predominantly originated in or near the reed belt from spring

    2015-10-01

    Structurally controlled Cu-Au mineralization in the historic Flatschach mining district (Styria, Austria) occurs in a NE-SW to NNE-WSW oriented vein system as multiple steep-dipping calcite-(dolomite)-quartz veins in amphibolite facies metamorphic rocks (banded gneisses/amphibolites, orthogneisses, metagranitoids) of the poly-metamorphosed Austroalpine Silvretta-Seckau nappe. Vein formation postdated ductile deformation events and Eoalpine (Late Cretaceous) peak metamorphism but predated Early to Middle Miocene sediment deposition in the Fohnsdorf pull-apart basin; coal-bearing sediments cover the metamorphic basement plus the mineralized veins at the northern edge of the basin. Three gold-bearing ore stages consist of a stage 1 primary hydrothermal (mesothermal?) ore assemblage dominated by chalcopyrite, pyrite and arsenopyrite. Associated minor minerals include alloclasite, enargite, bornite, sphalerite, galena, bismuth and matildite. Gold in this stage is spatially associated with chalcopyrite occurring as inclusions, along re-healed micro-fractures or along grain boundaries of chalcopyrite with pyrite or arsenopyrite. Sericite-carbonate alteration is developed around the veins. Stage 2 ore minerals formed by the replacement of stage 1 sulfides and include digenite, anilite, "blue-remaining covellite" (spionkopite, yarrowite), bismuth, and the rare copper arsenides domeykite and koutekite. Gold in stage 2 is angular to rounded in shape and occurs primarily in the carbonate (calcite, Fe-dolomite) gangue and less commonly together with digenite, domeykite/koutekite and bismuth. Stage 3 is a strongly oxidized assemblage that includes hematite, cuprite, and various secondary Cu- and Fe-hydroxides and -carbonates. It formed during supergene weathering. Stage 1 and 2 gold consists mostly of electrum (gold fineness 640-860; mean = 725; n = 46), and rare near pure gold (fineness 930-940; n = 6). Gold in stage 3 is Ag-rich electrum (fineness 350-490, n = 12), and has a

    2014-05-01

    The Postalm section in the Northern Calcareous Alps (Austria) covers an almost continuous succession of Santonian to Maastrichtian hemipelagic to pelagic sediments. Our detailed stratigraphic study starts with an in-depth evaluation of the R. calcarata total range zone. The implementation of a cyclostratigraphic model was followed by a high resolution assessment of foraminifera and nannoplankton communities of this interval (Wagreich et al., 2012). In the aim to expand the cyclostratigraphic framework for the Upper Cretaceous, a biostratigraphic sampling of the entire succession at Postalm was conducted. As cyclic sedimentation of marls and marly limestones prevails throughout the section, over 300 samples have been taken bed-by-bed. Foraminifera data suggest the outcrop covers an interval ranging from the uppermost Santonian Dicarinella asymetrica to the Maastrichtian Gansserina gansseri Zone (nannofossil zones CC17 to CC22). The lowermost part of the section displays a comparatively shallow shelf environment yielding high percentage of benthic foraminifera with a highly diverse community. However, we can observe a distinct deepening in the basal Campanian and towards the Maastrichtian. Stratigraphically younger parts (i.e. Upper Campanian and Maastrichtian) of the section are displaying a deeper palaeoenvironment. In this pelagic environment foraminifera packstones with marl intercalations dominate the lithology. The state of preservation of microfossils has to be considered as moderate to poor. Evidence for frequent turbidite events in the uppermost (Maastrichtian) part of the section was recorded. As isotope records of the previousely investigated calcarata interval at Postalm correlate well to other Campanian sections, we are confident to find a valuable proxy in the data from other subsections of this outcrop as well. The cyclostratigraphic evaluation of sedimentation cycles in combination with biostratigraphic data sheds light upon the duration of planktic

    The mechanism of deep reversible air circulation (the so called "chimney effect" or "wind tube") is known to be a process of ground overcooling in the lower and deeper parts of porous sediments and related landforms such as scree slopes or intact and relict rock glaciers. Warm air outflow emerging from relatively small voids within these mostly coarse-grained sediment bodies is sometimes noticeable. However, easier to identify are associated phenomena such as snowmelt windows, snow cover depressions and hoarfrost formations. Generally, these indications for warm air outflow are found at the upper part of scree slopes or the rooting zone of rock glaciers. Here we present widespread field evidences of hoarfrost from the pseudo-relict Schöneben Rock Glacier in the Seckauer Tauern Range, Austria located at E14°40'26'' and N47°22'31''. Herewith, a pseudo-relict rock glacier is defined as an intermediate rock glacier type between a relict and a climatic-inactive rock glacier, hence a relict rock glacier with locally isolated patches of permafrost. The rock glacier covers an area of about 0.11km2, ranges from ca. 1720 to 1905 m a.s.l., and consists predominantly of coarse-grained gneissic sediments with blocks up to a size of several cubic metres at the surface. In particular the lower part and some ridges in the central and upper part are covered by dwarf pines (pinus mugo) mirroring the flow structure of the previously active rock glacier. Isolated permafrost occurs presumably at the rooting zone of the rock glacier as indicated by evidences from a neighbouring rock glacier in a comparable setting. Field observations in November 2011 showed widespread occurrences of hoarfrost crystals growing around the funnel edge indicating the sublimation of vapour from warm funnels. Such hoarfrost sites were found at more than 50 single locations distributed over the entire rock glacier from the tongue to the rooting zone generally. The occurrence of hoarfrost can get classified

  17. Total Petroleum Systems of the North Carpathian Province of Poland, Ukraine, Czech Republic, and Austria

    2006-01-01

    Three total petroleum systems were identified in the North Carpathian Province (4047) that includes parts of Poland, Ukraine, Austria, and the Czech Republic. They are the Isotopically Light Gas Total Petroleum System, the Mesozoic-Paleogene Composite Total Petroleum System, and the Paleozoic Composite Total Petroleum System. The Foreland Basin Assessment Unit of the Isotopically Light Gas Total Petroleum System is wholly contained within the shallow sedimentary rocks of Neogene molasse in the Carpathian foredeep. The biogenic gas is generated locally as the result of bacterial activity on dispersed organic matter. Migration is also believed to be local, and gas is believed to be trapped in shallow stratigraphic traps. The Mesozoic-Paleogene Composite Total Petroleum System, which includes the Deformed Belt Assessment Unit, is structurally complex, and source rocks, reservoirs, and seals are juxtaposed in such a way that a single stratigraphic section is insufficient to describe the geology. The Menilite Shale, an organic-rich rock widespread throughout the Carpathian region, is the main hydrocarbon source rock. Other Jurassic to Cretaceous formations also contribute to oil and gas in the overthrust zone in Poland and Ukraine but in smaller amounts, because those formations are more localized than the Menilite Shale. The Paleozoic Composite Total Petroleum System is defined on the basis of the suspected source rock for two oil or gas fields in western Poland. The Paleozoic Reservoirs Assessment Unit encompasses Devonian organic-rich shale believed to be a source of deep gas within the total petroleum system. East of this field is a Paleozoic oil accumulation whose source is uncertain; however, it possesses geochemical similarities to oil generated by Upper Carboniferous coals. The undiscovered resources in the North Carpathian Province are, at the mean, 4.61 trillion cubic feet of gas and 359 million barrels of oil. Many favorable parts of the province have been

    Geoconservation potential is, in our approach, closely linked to the spatial distribution of geomorphological sites and thus, geomorphological inventories. Detailed geomorphological maps are translated, using a standardized workflow, into polygonal maps showing the potential geoconservation value of landforms. A new development is to semi-automatically extract in a GIS geomorphological information from high resolution topographical data, such as LiDAR, and combine this with conventional data types (e.g. airphotos, geological maps) into geomorphological maps. Such hybrid digital geomorphological maps are also easily translated into digital information layers which show the geoconservation potential in an area. We present a protocol for digital geomorphological mapping illustrated with an example for the municipality of Lech in Vorarlberg (Austria). The protocol consists of 5 steps: 1. data preparation, 2. generating training and validation samples, 3. parameterization, 4. feature extraction, and 5. assessing classification accuracy. The resulting semi-automated digital geomorphological map is then further validated, in two ways. Firstly, the map is manually checked with the help of a series of digital datasets (e.g. airphotos) in a digital 3D environment, such as ArcScene. The second validation is field visit, which preferably occurs in parallel to the digital evaluation, so that updates are quickly achieved. The final digital and coded geomorphological information layer is converted into a potential geoconservation map by weighting and ranking the landforms based on four criteria: scientific relevance, frequency of occurrence, disturbance, and environmental vulnerability. The criteria with predefined scores for the various landform types are stored in a separate GIS attribute table, which is joined to the attribute table of the hybrid geomorphological information layer in an automated procedure. The results of the assessment can be displayed as the potential

    Background In recent years various studies showed, that hepatitis E virus (HEV) is a growing public health problem in many developed countries. Therefore, HEV infections might bear a transmission risk by blood transfusions. The clinical relevance still requires further investigations. The aim of this study was to provide an overview of acute HEV infections in Upper Austrian blood donors as well as a risk estimation of this transfusion-related infection. Methods and Findings A total of 58,915 blood donors were tested for HEV RNA using a commercial HEV RT-PCR Kit. 7 of these donors (0.01%) were PCR-positive with normal laboratory parameters in absence of clinical signs of hepatitis. Viral load determined by quantitative real-time PCR showed a HEV nucleic acid concentration of 2,217 293,635 IU/ml. At follow-up testing (2–11 weeks after donation) all blood donors had negative HEV RNA results. Additionally, genotyping was performed by amplification and sequencing of the ORF1 or ORF2 region of the HEV genome. All HEV RNA positive donor samples revealed a genotype 3 isolate. For the antibody screening, anti-HEV IgM and IgG were detected by ELISA. Follow up serological testing revealed that no donor was seropositive for HEV IgM or IgG antibodies at time of donation. Moreover, we verified the prevalence of anti-HEV IgG in 1,203 of the HEV RNA negative tested blood donors. Overall 13.55% showed positive results for anti-HEV IgG. Conclusions In the presented study, we investigated HEV infections in blood donations of Upper Austria over 1 year. We concluded that 1 out of 8,416 blood donations is HEV RNA positive. Seroprevalence of anti HEV IgG results in an age-related increase of 13.55%. Therefore, based on this data, we recommend HEV-PCR screening to prevent transmission of hepatitis E virus by transfusion.

    Objective To assess the influence of cognitive, functional and behavioral factors, co-morbidities as well as caregiver characteristics on driving cessation in dementia patients. Methods The study cohort consists of those 240 dementia cases of the ongoing prospective registry on dementia in Austria (PRODEM) who were former or current car-drivers (mean age 74.2 (±8.8) years, 39.6% females, 80.8% Alzheimer’s disease). Reasons for driving cessation were assessed with the patients’ caregivers. Standardized questionnaires were used to evaluate patient- and caregiver characteristics. Cognitive functioning was determined by Mini-Mental State Examination (MMSE), the CERAD neuropsychological test battery and Clinical Dementia Rating (CDR), activities of daily living (ADL) by the Disability Assessment for Dementia, behavior by the Neuropsychiatric Inventory (NPI) and caregiver burden by the Zarit burden scale. Results Among subjects who had ceased driving, 136 (93.8%) did so because of “Unacceptable risk” according to caregiver’s judgment. Car accidents and revocation of the driving license were responsible in 8 (5.5%) and 1(0.7%) participant, respectively. Female gender (OR 5.057; 95%CI 1.803–14.180; p = 0.002), constructional abilities (OR 0.611; 95%CI 0.445–0.839; p = 0.002) and impairment in Activities of Daily Living (OR 0.941; 95%CI 0.911–0.973; p<0.001) were the only significant and independent associates of driving cessation. In multivariate analysis none of the currently proposed screening tools for assessment of fitness to drive in elderly subjects including the MMSE and CDR were significantly associated with driving cessation. Conclusion The risk-estimate of caregivers, but not car accidents or revocation of the driving license determines if dementia patients cease driving. Female gender and increasing impairment in constructional abilities and ADL raise the probability for driving cessation. If any of these factors also relates to

    Translating guidelines into nursing practice remains a considerable challenge. Until now, little attention has been paid to which interventions are used in practice to implement guidelines on changing clinical nursing practice. This cross-sectional study determined the current ranges and rates of implementation-related interventions in Austria, Germany, and The Netherlands and explored possible differences between these countries. An online questionnaire based on the conceptual framework of implementation interventions (professional, organizational, financial, and regulatory) from the Cochrane Effective Practice and Organization of Care (EPOC) data collection checklist was used to gather data from nursing homes and hospitals. Provision of written materials is the most frequently used professional implementation intervention (85%), whereas changes in the patient record system rank foremost among organisational interventions (78%). Financial incentives for nurses are rarely used. More interventions were used in Austria and Germany than in The Netherlands (20.3/20.2/17.3). Professional interventions are used more frequently in Germany and financial interventions more frequently in The Netherlands. Implementation efforts focus mainly on professional and organisational interventions. Nurse managers and other responsible personnel should direct their focus to a broader array of implementation interventions using the four different categories of EPOC's conceptual framework.

    We aimed to investigate the prevalence and correlates of smoking in people living with HIV (PLWHIV) in Germany and Austria and their readiness to quit. A total of 447 consecutive patients with confirmed positive HIV status who were treated in different outpatient HIV centres in Austria and Germany were included. Nicotine dependence and stages of change were assessed by standardized questionnaires, and this was confirmed by measuring exhaled carbon monoxide. Prevalence of smoking was 49.4%. According to a multivariate logistic regression analysis, higher age (for each year of life OR = 0.96; 95% CI 0.92-1.00) and tertiary education level (OR = 0.43; 95% CI 0.15-0.79) were associated with a lower chance, and occasional (OR = 3.75; 95% CI 1.74-8.07) and daily smoking of the partner (OR 8.78; 95% CI 4.49-17.17) were significantly associated with a higher chance of smoking. Moderate (OR = 3.41; 95% CI = 1.30-9.05) and higher nicotine dependency level (OR = 3.40; 95% CI 1.46-7.94), were significantly associated with higher chance, and older age (for each year of life OR = 0.95; 95% CI = 0.91-0.99), with lower chance for readiness to quit smoking. Those results may be used to address preventive measures to quit smoking aimed at PLWHIV and the importance of addressing smoking habits.

    The biogeographical centers of origin of important food crops-called Vavilov centers-are considered to be crucial sources of genetic diversity for present and future crop-breeding programs and thus for human food safety worldwide. Global environmental change and more intensified modes of crop production may cause genetic erosion (loss of traditional crop varieties and loss of crop wild relatives), especially in Vavilov centers. The present study focused on how the risk of genetic erosion (or loss of agro-biodiversity) is perceived in comparison to 16 other risk topics by experts and lay people in Austria and China. The most striking result was that genetic erosion was perceived to be an exceptionally unknown and uncertain risk topic, given that only genetically modified organisms (GMOs) were perceived as being even more uncertain. As a consequence of the high uncertainty, the idea of applying the precautionary principle to further prevent genetic erosion is discussed. An unprecedented finding-one that differs from Austrian participants-is that the Chinese have a higher perceived control over all risk topics. The increased perception of controllability in China is discussed in light of the theory of reflexive modernization. This theory strives to explain the increased critical attitude in Western countries such as Austria toward scientific innovations and toward the idea that everything can be calculated and mastered at will. By revealing different notions of risk perception, this research also provides additional scientific input to risk communication efforts for public education.

    Cryptocrystalline magnesite (CM) occurs all over the world predominantly in ultramafic rocks and within those mainly in ophiolite zones. The mineralization forms either veins and networks, which are strictly controlled by regional fault tectonics (Kraubath-type), or nodules and layers, which occur in sediments above the ophiolite close to the paleosurface (Bela Stena type). These types are well established and named after their type deposits in Austria and Serbia, respectively (Pohl, 1990; Prochaska, 2000; Wilson & Ebner, 2006). Stable isotopic studies of CM showed that in comparison to sparry magnesite CM has lower δ13C values (-18‰ to -6‰) and more constant δ18O values (+22‰ to +29‰) (Kralik et al., 1989). Furthermore, it was observed that the Kraubath-type and Bela Stena-type CM differ in their isotopic composition in that the latter is characterised by higher δ13C (-1‰ to +4‰) and δ18O values (+26‰ to +36‰) (Jurković & Pamić, 2003). The formation of CM is still a subject of debate. The δ18O values suggests formation temperatures below 80°C (Kralik et al., 1989; Ece et al., 2005). The C isotope data indicate that the C was either derived from the atmosphere or by decarboxylation of organic-rich sediments (Zedef et al. 2000). Our research addresses the following major questions: (a) What are the reasons for the difference in stable isotopic composition between the Kraubath and the Bela Stena-type? (b) Is it possible to distinguish different types of mineralizations within a deposit using stable isotope data and can this information be applied as a tool for CM exploration? (c) Do the individual isotopic patterns of the individual deposits reflect different conditions for formation or later (post-mineralization) alteration events? Our investigations were concentrated on the type locality in Kraubath (Austria) as well as on some currently operating deposits in the magnesite districts of Eskişehir and Tavşanlı (western Anatolia/ Turkey

Treatments and potential new therapeutic strategies for these hepatopathies were discussed during the 50th International Liver Congress organized by the European Association for the Study of the Liver. Echoing epidemiological facts and a high social interest for hepatitis C virus infection, new findings with investigational and potential new therapies for the disease centered much of the attention at the conference. Nevertheless, new research was also reported related to potential improvements in how other liver diseases, particularly hepatitis B virus infection, hepatocellular carcinoma and a range of inflammatory and immune-mediated liver diseases, including rare hereditary diseases that should never be forgotten.

    Terrestrial laser scanners (TLS) have widely been used for high spatial resolution data acquisition of topographic features and geomorphic analyses. Existing applications encompass different landslides including rockfall, translational or rotational landslides, debris flow, but also coastal cliff erosion, braided river evolution or river bank erosion. The main advantages of TLS are (a) the high spatial sampling density of XYZ-measurements (e.g. 1 point every 2-3 mm at 10 m distance), particularly in comparison with the low data density monitoring techniques such as GNSS or total stations, (b) the millimeter accuracy and precision of the range measurement to centimeter accuracy of the final DEM, and (c) the highly dense area-wide scanning that enables to look through vegetation and to measure bare ground. One of its main constraints is the temporal resolution of acquired data due to labor costs and time requirements for field campaigns. Thus, repetition measurements are generally performed only episodically. However, for an increased scientific understanding of the processes as well as for early warning purposes, we present a novel permanent 3D monitoring setup to increase the temporal resolution of TLS measurements. This accounts for different potential monitoring deliverables such as volumetric calculations, spatio-temporal movement patterns, predictions and even alerting. This system was installed at the active Salcher landslide in Gresten (Austria) that is situated in the transition zone of the Gresten Klippenbelt (Helvetic) and the Flyschzone (Penninic). The characteristic lithofacies are the Gresten Beds of Early Jurassic age that are covered by a sequence of marly and silty beds with intercalated sandy limestones. Permanent data acquisition can be implemented into our workflow with any long-range TLS system offering fully automated capturing. We utilize an Optech ILRIS-3D scanner. The time interval between two scans is currently set to 24 hours, but can be

    The FLUXNET project [1] aims at quantifying the magnitude and controls on the CO2, H2O and energy exchange of terrestrial ecosystems. Ideally, the various biomes of the Earth would be sampled in proportion to their spatial extent - in reality, however, study site selection is usually based on other (more practical) criteria so that a bias exists towards certain biomes and ecosystem types. This may be problematic because FLUXNET data are used to calibrate/parameterize models at various scales - if certain ecosystems are poorly replicated this may bias model predictions. Here we present data from a project in Tyrol/Austria where we have been investigating the CO2, H2O and energy exchange of five grassland sites during 2005-2007. The five permanent grassland sites were exposed to similar climate, but differed slightly in management. In a FLUXNET style approach, any of these sites might have been selected for making long-term flux measurements - the aim of this project was to examine the representativeness of these sites and, if evident, elucidate the causes for and controls on differences between sites. To this end we conducted continuous eddy covariance flux measurements at one (anchor) site [2, 3], and episodic, month long flux measurements at the four additional sites using a roving eddy covariance tower. These data were complemented by measurements of environmental drivers, the amount of above ground phytomass and basic data on vegetation and soil type, as well as management. Data are subject to a rigorous statistical analysis in order to quantify significant differences in the CO2, H2O and energy exchange between the sites and to identify the factors which are responsible for these differences. In the present contribution we report results on CO2 fluxes. Our major findings are that (i) site-identity of the surveyed grassland ecosystems was a significant factor for the net ecosystem CO2 exchange (NEE), somewhat less for gross primary production (GPP) and not for

    The transdisciplinary project INNrisk, in collaboration with public risk and disaster management, investigates the severe floods of 22nd and 23rd of August, 2005, and their effects within the federal province of Tyrol. The inundation and accompanying processes (e.g. debris flows, log jams, underwashing of infrastructure) caused by the river Inn and its tributaries created a dangerous situation for Tyrol. The overall economic loss of direct assets is said to amount to ca. 500 million Euros. Climate change has basically been causing a statistical increase of damaging floods within the Alpine Space in recent decades while increasing vulnerability at the same time. The expansion of settlements is one factor in the threat to large numbers of people and growing economic losses. However, the disasters of the last decade provide an opportunity for analysing the flood process in terms of natural-science and geographical aspects as well as in terms of economic and statistical ones. This should lead to a better understanding of triggers and effects in those areas where humans are active and form the basis for mitigation and adaptation strategies. The results of such analyses represent valuable information for public risk and disaster management, particularly in presenting the effects on public and private households. The INNrisk project primarily aims to assess the framework conditions in systemic-legal terms and to analyse human actions during the floods in relation to various plans and the damage potentials resulting from them. The assessed losses depend to a great extent on the actions taken during the emergency and on flood operations by the public emergency management and local fire departments, which are in charge of floods and related processes in the case of Austria. Assessment will be carried out by analysing a database of series of human actions for the duration of the emergeny and increased risk. The project also strives to arrive at a macro- and mesoeconomic

    The Vienna basin is a pull-apart basin located at the contact between the Alpine arc and the Eurasian plate, with the Eastern Alps to the West, the Western Carpathian to the East, the Bohemian massif to the North, and the Pannonian basin to the South. The southern border of this basin, called the Vienna Basin Fault System (VBFS), is accommodating part of the extrusion of the Pannonian basin (~1-2 mm/yr) due to the convergence between the Adriatic microplate and the Eurasian plate. The VBFS is a sinistral strike-slip fault and one of the most active fault in Austria. Along the VBFS, the seismicity is mainly concentrated in separate clusters with a spacing of approximately 20 km. In 2000 and 2013, two sequences constituted by two main shocks and 20-30 aftershocks occurred in one of these clusters located close to Ebreichsdorf, approximately 30 km south of Vienna. We focus here on the sequence of 2013 whose earthquakes were relocated using the double-difference method. The two main shocks, with local magnitudes of 4.2 and very similar focal mechanisms (N63, sinistral strike-slip), seem to be almost collocated. The aftershocks are located mainly to the northwest and at shallower depths compared with the main shocks. In order to better understand the relationships between the two main shocks and their aftershocks, we use two simple models of Coulomb failure stress to investigate possible coseismic static stress transfer between the main shocks and the aftershocks: the constant apparent friction model and the isotropic poroelastic model. The Coulomb failure stress change at the location of most aftershocks is positive but under 0.01 MPa. Aftershock triggering due to coseismic static stress is then unlikely. On the other hand, two other mechanisms could drive this sequence i.e., rapid non-linear pore pressure diffusion along the fault plane or aseismic slip. Given inter-event distances and times of ~0.5-1 km and hours to days, respectively, a high hydraulic diffusivity of

    2015-04-01

    Glacierized high-mountain environments are characterized by active morphodynamics, favouring the rapid appearance and disappearance of lakes. On the one hand, such lakes indicate high-mountain environmental changes such as the retreat of glaciers. On the other hand, they are sometimes susceptible to sudden drainage, leading to glacial lake outburst floods (GLOFs) putting the downstream population at risk. Whilst high-mountain lakes have been intensively studied in the Himalayas, the Pamir, the Andes or the Western Alps, this is not the case for the Eastern Alps. A particular research gap, which is attacked with the present work, concerns the western part of Austria. We consider a study area of approx. 6,140 km², covering the central Alps over most of the province of Tyrol and part of the province of Salzburg. All lakes ≥250 m² located higher than 2000 m asl are mapped from high-resolution Google Earth imagery and orthophotos. The lakes are organized into seven classes: (i) ice-dammed; near-glacial (ii) moraine-dammed and (iii) bedrock-dammed; (iv) moraine-dammed and (v) bedrock-dammed distant to the recent glaciers; (vi) landslide-dammed; (vii) anthropogenic. The temporal development of selected lakes is investigated in detail, using aerial photographs dating back to the 1950s. 1045 lakes are identified in the study area. Only eight lakes are ice-dammed (i). One third of all lakes is located in the immediate vicinity of recent glacier tongues, half of them impounded by moraine (ii), half of them by bedrock (iii). Two thirds of all lakes are impounded by features (either moraines or bedrock) shaped by LIA or Pleistocenic glaciers at some distance to the present glacier tongues (iv and v). Only one landslide-dammed lake (vi) is identified in the study area, whilst 21 lakes are of anthropogenic origin (vii). 72% of all lakes are found at 2250-2750 m asl whilst less than 2% are found above 3000 m asl. The ratio of rock-dammed lakes increases with increasing

    The Moldanubian superunit is part of the internal zone of the Variscan Orogen in Europe and borders on the Saxothuringian and Sudetes zones in the north. In the south, it is blanketed by the Alpine foreland molasse. Tectonically it is subdivided into the Moldanubian Nappes (MN), the South Bohemian Batholith (SBB) and the Bavarian Nappes. This work describes the ~ 500 m thick Freyenstein shear zone, which is located at the southern border of the Bohemian Massif north and south of the Danube near Freyenstein (Strudengau, Lower Austria). The area is built up by granites of Weinsberg-type, which are interlayered by numerous dikes and paragneisses of the Ostrong nappe system. These dikes include medium grained granites and finegrained granites (Mauthausen-type granites), which form huge intrusions. In addition, smaller intrusions of dark, finegrained diorites und aplitic dikes are observed. These rocks are affected by the Freyenstein shear zone und ductily deformed. Highly deformed pegmatoides containing white mica crystals up to one cm cut through the deformed rocks and form the last dike generation. The Freyenstein shear zone is a NE-SW striking shear zone at the eastern edge of the SBB. The mylonitic foliation is dipping to the SE with angles around 60°. Shear-sense criteria like clast geometries, SĆ structures as well as microstructures show normal faulting top to S/SW with steep (ca. 50°) angles. The Freyenstein shear zone records a polyphase history of deformation and crystallization: In a first phase, mylonitized mineral assemblages in deformed granitoides can be observed, which consist of pre- to syntectonic muscovite-porphyroclasts and biotite as well as dynamically recrystallized potassium feldspar, plagioclase and quartz. The muscovite porphyroclasts often form mica fishes and show top to S/SW directed shear-sense. The lack of syntectonic chlorite crystals points to metamorphic conditions of lower amphibolite-facies > than 450° C. In a later stage fluid

    A rock slide on to the clayey - silty - sandy - pebbly masses in the Gschliefgraben (Upper Austria province, Lake Traunsee) having occurred in 2006 as well as the humid autumn of 2007 triggered an earth flow comprising a volume up to 5 mill m³ and moving with a maximum displacement velocity of 5 m/day during the winter of 2007-2008. The possible damage was estimated up to 60 mill € due to possible destruction of houses and of a road to a settlement with heavy tourism. Exploratory drillings revealed that the moving mass consists of an alternate bedding of thicker, less permeable clayey - silty layers and thinner, more permeable silty - sandy - pebbly layers. The movement front ran ahead in the creek bed. Therefore it was assumed that water played an important role and the earth flow moved due to soaking of water into the ground from the area of the rock slide downslope. Inclinometer measurements showed that the uppermost, less permeable layer was sliding on a thin, more permeable layer. The movement process was analysed by numerical models (FLAC) and by conventional calculations in order to assess the hazard. The coupled flow and mechanical models showed that sections of the less permeable layer soaked with water were sliding on the thin, more permeable layer due to excessive watering out of the more permeable layer. These sections were thrust over the downward lying, less soaked areas, therefore having higher strength. The material thrust over the downward lying, less soaked areas together with the moving front of pore water pressures caused the downward material to fail and to be thrust over the downslope lying material in a distance of some 50 m. Thus a cyclic process was created without any indication of a sudden sliding of the complete less permeable layer. Nevertheless, the inhabitants of 15 houses had to be evacuated for safety reasons. They could return to their homes after displacement velocities had decreased. Displacement monitoring by GPS showed that

    The WISDOM (Water Ice Subsurface Deposit Observations on Mars) Ground Penetrating Radar (GPR) is among the instruments selected as part of ESA's 2018 ExoMars Rover mission, whose scientific objectives are to search for signs of past and present life and to investigate the planet's subsurface. Combined with the rover, the GPR will provide high resolution observations of the structure of the shallow subsurface and assist in the identification and location of sedimentary layers or massive ice deposits, where organic molecules are the most likely to be found and well-preserved. The resulting data sets will also be a valuable tool for determining the nature, location and extent of potential targets for drilling. WISDOM prototypes, representative of the final flight model, are currently being field tested in various Mars analogue and cold-climate environments. In April 2012, members of the WISDOM team brought two development prototypes to an Alpine ice cave in Dachstein, Austria, to field test the instrument and participate in the Mars Simulation organized by the Austrian Space Forum. The GPRs were tested on 3 different platforms including the radio-controlled "Magma White" Rover from ABM Space Education in Poland. Radar investigations were conducted in four different cave environments, measuring ice thickness, stratigraphy, fracture geometry, and basal topography. Data sets processed and analyzed prove to be in agreement with the shallow environment characteristics determined by direct observation and previously obtained with commercial GPRs. From a geoelectrical point of view, massive ice containing a small amount of impurities can be approximate as a rather homogeneous medium. A massive ice unit will appear on a radargram as an area with no noticeable signal return, due to the little backscattered signal. Ice is also a low conductivity medium which leads to a deep penetration of the electromagnetic waves. The radargrams obtained from WISDOM data are consistent with

    Geochronology, based on pollen and isotopes, of a Late Glacial gyttja deposit in Vorarlberg, Austria. The Gasserplatz, a peat biotope with histosols, is situated 1 km NE of Feldkirch in Vorarlberg. During the last deglaciation, i.e. the retreat of the Ill glacier by the end of the Oldest Dryas, a tiny ice-marginal lake here developed in a sheltered position at an elevation of 439 m.a.s. After local deglaciation, lacustrine carbonate (chalk gyttja) deposited. At the beginning of the Holocene the lake changed into a peat bog with peat accumulation. The soil archive of the Gasserplatz contains a 6m undisturbed high quality paleoecological record, a sequence of Late Glacial and Holocene deposits. To ‘read' this record we applied pollen and isotope analysis on the Late Glacial lacustrine carbonate deposits. Research on the Gasserplatz profile will be continued by pollen analysis and radiocarbon dating of the Holocene peat deposits. The sedimentation in the former lake started with sterile clay deposition (70 cm) on till. Around 13,000 BP (radiocarbon years) deposition of a 270 cm lacustrine carbonate section started. The deposition rate was rather constant, about 0.85mm per year during almost 3000 years. Peat accumulation started at around 9,500 BP. The pollen diagram of the lake marl deposits shows the vegetation development starting at 13,000 BP. The oldest spectra (535-500 cm) reflect a pioneer vegetation (Artemisia, Helianthemum, Gramineae), followed by invasions of Betula, Juniperus and Pinus. Oscillations in Betula percentages are probably caused by temperature variations. 14C dating of the lake marl deposits is not straightforward. Depending on the source materials (shale's, organic mud, peat) we found different ages at the same depth in the core. Shale's and fibric peat provide the best results for a correct geochronology of the record. 13C variations show (1) periods without and with biomass production, and (2) qualitative properties of produced biomass

    There is increasing evidence for the spread of West Nile virus (WNV) in southern, eastern and central Europe. In parallel, another flavivirus, the antigenically closely related Usutu virus, was introduced from Africa and first detected in Austria (2001), followed by Spain (2003), Hungary (2005), Italy (2006), Switzerland (2006) and Germany (2007). In Austria, human WNV infections have not previously been documented, although the virus was isolated from birds and detected in mosquitoes in 2008 and 2009. We therefore conducted a retrospective search for human cases of WNV infection using serum and cerebrospinal fluid samples collected from patients with central nervous system (CNS) disease in the summers of 2009, 2010 and 2011. Although all samples were negative for WNV by polymerase chain reaction, quantitative evaluation of standardised antibody assays with purified flavivirus antigens (including Usutu virus, which cross-reacts with WNV even in neutralisation assays) provided serological evidence for three autochthonous WNV infections in Austria: two in 2009 and one in 2010. Our data highlight the importance of raising awareness of WNV infections in Austria and neighbouring countries and suggest including testing for this infection in routine diagnostic practice of CNS diseases.

    Gender-fair language consists of the symmetric linguistic treatment of women and men instead of using masculine forms as generics. In this study, we examine how the use of gender-fair language affects readers' support for social initiatives in Poland and Austria. While gender-fair language is relatively novel in Poland, it is well established in Austria. This difference may lead to different perceptions of gender-fair usage in these speech communities. Two studies conducted in Poland investigate whether the evaluation of social initiatives (Study 1: quotas for women on election lists; Study 2: support for women students or students from countries troubled by war) is affected by how female proponents (lawyers, psychologists, sociologists, and academics) are referred to, with masculine forms (traditional) or with feminine forms (modern, gender-fair). Study 3 replicates Study 2 in Austria. Our results indicate that in Poland, gender-fair language has negative connotations and therefore, detrimental effects particularly when used in gender-related contexts. Conversely, in Austria, where gender-fair language has been implemented and used for some time, there are no such negative effects. This pattern of results may inform the discussion about formal policies regulating the use of gender-fair language. PMID:26582996

    In the framework of the European InterregIV Italy/Austria project: "HAREIA - Historical and Recent Earthquakes in Italy and Austria" the Central Institute for Meteorology and Geodynamics (ZAMG) and Mathematic and Geosciences Department of University of Trieste (DMG) are upgrading the transfrontier seismic network of South-Eastern Alps with new 12 accelerometric stations to enhance the strong motion instrument density near the Austria/Italy border. Various public institutions of the provinces Alto Adige (Bolzano Province), Veneto (ARPAV) and Friuli Venezia Giulia (Regional Civil Defense) in Italy and in the Austrian province of Tyrol are involved in the project. The site selection was carried out to improve the present local network geometry thus meeting the needs of public Institutions in the involved regions. In Tyrol and Alto Adige some strategic buildings (hospitals and public buildings) have been selected, whereas in Veneto and Friuli Venezia Giulia the sites are in the free field, mainly located near villages. The instruments will be installed in an innovative box, designed by ZAMG, that provides electric and water isolation. The common choice regarding the instrument selection has been the new Kinemetrics Basalt ® accelerograph to guarantee homogeneity with the already installed instrumentation and compatibility with the software already in use at the different seismic institutions in the area. Prior to deployment the equipment was tested at the Conrad Observatory and a common set-up has been devised. The Conrad Observatory, seismically particularly quiet, permits to analyze both the sensor and the acquisition system noise. The instruments were connected to the network and the data sent in real-time to the ZAMG data center in Vienna and the DMG data center in Trieste. The data have been collected in the database and analyzed using signal processing modules PQLX and Matlab. The data analysis of the recordings at the ultra-quiet Conrad Observatory pointed out

    Climate and Land Use Change can have severe impacts on natural water resources needed for domestic, agricultural and industrial water use. In order to develop adaptation strategies, it is necessary to assess the present and future vulnerability of the water resources on the basis of water quantity, water quality and adaptive capacity indicators. Therefore a methodological framework was developed within the CC-Ware project and a detailed assessment was performed for Austria. The Water Exploitation Index (WEI) is introduced as a quantitative indicator. It is defined as the ratio between the water demand and the water availability. Water availability is assessed by a high resolution grid-based water balance model, utilizing the meteorological information from bias corrected regional climate models. The demand term can be divided into domestic, agricultural and industrial water demand and is assessed on the water supply association level. The Integrated Groundwater Pollution Load Index (GWPLI) represents an indicator for areas at risk regarding water quality, considering agricultural loads (nitrate pollution loads), potential erosion and potential risks from landfills. Except for the landfills, the information for the current situation is based on the CORINE Landcover data. Future changes were predicted utilizing the PRELUDE land use scenarios. Since vulnerability is also dependent on the adaptive capacity of a system, the Adaptive Capacity Index is introduced. The Adaptive Capacity Index thereby combines the Ecosystem Service Index (ESSI), which represents three water related ecosystem services (Water Provision, Water Quantity Regulation and Water Quality Regulation) and the regional economic capacity expressed by the gross value added. On the basis of these indices, the Overall Vulnerability of the water resources can be determined for the present and the future. For Austria the different indices were elaborated.

    Earthquakes are commonly seen as unpredictable. Even when scientists believe an earthquake is likely, it is still hard to understand the indications observed, as well as their theoretical and practical implications. There is some controversy surrounding the concept of using animals as a precursor of earthquakes. Nonetheless, several institutes at University of Natural Resources and Life Sciences, and Vienna University of Technology, both Vienna, Austria, and Syiah Kuala University, Banda Aceh, as well as Terramath Indonesia, Buleleng, both Indonesia, cooperate in a long-term project, funded by Red Bull Media House, Salzburg, Austria, which aims at getting some decisive step forward from anecdotal to scientific evidence of those interdependencies, and show their possible use in forecasting seismic hazard on a short-term basis. Though no conclusive research has yet been published, an idea in this study is that even if animals do not respond to specific geophysical precursors and with enough notice to enable earthquake forecasting on that basis, they may at least enhance, in conjunction with other indications, the degree of certainty we can get of a prediction of an impending earthquake. In Indonesia, indeed, before the great earthquakes of 2004 and 2005, ominous geophysical as well as biological phenomena occurred (but were realized as precursors only in retrospect). Numerous comparable stories can be told from other times and regions. Nearly 2000 perceptible earthquakes (> M3.5) occur each year in Indonesia. Also, in 2007, the government has launched a program, focused on West Sumatra, for investigating earthquake precursors. Therefore, Indonesia is an excellent target area for a study concerning possible interconnections between geophysical and biological earthquake precursors. Geophysical and atmospheric measurements and behavioral observation of several animal species (elephant, domestic cattle, water buffalo, chicken, rat, catfish) are conducted in three areas

  8. Evaluation of the biomass potential for the production of lignocellulosic bioethanol from various agricultural residues in Austria and Worldwide

    Due to the fact that the resources of fossil fuels are steadily decreasing, researchers have been trying to find alternatives over the past few years. As bioethanol of the first generation is based on potential food, its production has become an increasingly controversial topic. Therefore the focus of research currently is on the production of bioethanol of the second generation, which is made from cellulosic and lignocellulosic materials. However, for the production of bioethanol of the second generation the fibres have to be pre-treated. In this work the mass balances of various agricultural residues available in Austria were generated and examined in lab scale experiments for their bioethanol potential. The residues were pretreatment by means of state of the art technology (steam explosion), enzymatically hydrolysed and fermented with yeast to produce ethanol. Special attention was paid the mass balance of the overall process. Due to the pretreatment the proportion of cellulose increases with the duration of the pre-treatment, whereby the amount of hemicellulose decreases greatly. However, the total losses were increasing with the duration of the pre-treatment, and the losses largely consist of hemicellulose. The ethanol yield varied depending on the cellulose content of the substrates. So rye straw 200 °C 20 min reaches an ethanol yield of 169 kg/t, by far the largest yield. As result on the basis of the annual straw yield in Austria, approximately 210 000 t of bioethanol (266 million litres) could be produced from the straw of wheat (Triticum vulgare), rye (Secale cereale), oat (Avena sativa) and corn (Zea mays) as well as elephant grass (Miscanthus sinensis) using appropriate pre-treatment. So the greenhouse gas emissions produced by burning fossil fuels could be reduced significantly. About 1.8 million tons of motor gasoline are consumed in Austria every year. The needed quantity for a transition to E10 biofuels could thus be easily provided by bioethanol

The following extraintestinal helminth species were detected: Taenia taeniaeformis (liver), Calodium hepaticum (liver), and Echinococcus multilocularis DNA (liver) in the common vole; and Taenia taeniaeformis (liver), Calodium hepaticum (liver), and Taenia crassiceps (musculature) in the water vole. Infestations with Toxocara canis and Trichinella sp. were not found. Our study documents the first description of E. multilocularis DNA in the intermediate host (Microtus arvalis) and of other medically relevant extraintestinal helminths in common and water voles in Austria.

    Greenhouses in botanical or zoological gardens are home to dozens of species of invertebrates that were introduced alongside plants or potting soil. Our study presents the description of an alien species of earwig, Euborellia arcanum sp. nov., found in tropical greenhouses in Leipzig and Potsdam (Germany) and in Vienna (Austria), including information about its biology in breeding culture. The species was most likely introduced into Europe by way of plants or plant matter from Florida, but the region of its natural habitat is unknown. The sequence of the mitochondrial gene cytochrome c oxidase subunit I (COI) was also evaluated and added to GenBank as a DNA barcode for further identification. PMID:26248909

    Target-orientated prevention and effective crisis management can reduce or avoid damage and save lives in case of a strong earthquake. To achieve this goal, a project for automatic generated ShakeMaps (maps of ground motion and shaking intensity) and updating the Austrian hazard map was started at ZAMG (Zentralanstalt für Meteorologie und Geodynamik) in 2015. The first goal of the project is set for a near-real-time generation of ShakeMaps following strong earthquakes in Austria to provide rapid, accurate and official information to support the governmental crisis management. Using newly developed methods and software by SHARE (Seismic Hazard Harmonization in Europe) and GEM (Global Earthquake Model), which allows a transnational analysis at European level, a new generation of Austrian hazard maps will be ultimately calculated. More information and a status of our project will be given by this presentation.

    Human reproduction is a biological phenomenon, however, sociocultural factors such as marital status influence pregnancy outcome and reproductive success. In the present study the impact of maternal marital status on pregnancy outcome was tested for all births, which had taken place in Austria between 1999 and 2004, which met the following criteria: single births, nulliparity, mothers older than 19 years (n = 179 830). The rate of preterm delivery (< 37 beginning weeks of gestation) and rate of low birth weight (< 2500 g) among term births were significantly higher among unmarried mothers in comparison to married mothers. Additionally the newborns of unmarried mothers were significantly lighter and shorter than those of married mothers. This was especially true of immigrant mothers. No significant differences between married and unmarried mothers were found regarding mode of delivery. Even at the beginning of the 21st century unmarried status represents an important stress factor for pregnant women.

    We aimed to investigate the prevalence and correlates of smoking in people living with HIV (PLWHIV) in Germany and Austria and their readiness to quit. A total of 447 consecutive patients with confirmed positive HIV status who were treated in different outpatient HIV centres in Austria and Germany were included. Nicotine dependence and stages of change were assessed by standardized questionnaires, and this was confirmed by measuring exhaled carbon monoxide. Prevalence of smoking was 49.4%. According to a multivariate logistic regression analysis, higher age (for each year of life OR = 0.96; 95% CI 0.92–1.00) and tertiary education level (OR = 0.43; 95% CI 0.15–0.79) were associated with a lower chance, and occasional (OR = 3.75; 95% CI 1.74–8.07) and daily smoking of the partner (OR 8.78; 95% CI 4.49–17.17) were significantly associated with a higher chance of smoking. Moderate (OR = 3.41; 95% CI = 1.30–9.05) and higher nicotine dependency level (OR = 3.40; 95% CI 1.46–7.94), were significantly associated with higher chance, and older age (for each year of life OR = 0.95; 95% CI = 0.91–0.99), with lower chance for readiness to quit smoking. Those results may be used to address preventive measures to quit smoking aimed at PLWHIV and the importance of addressing smoking habits. PMID:26919722

    This qualitative study was carried out to investigate the effectiveness of cognitive-behavioral therapy (CBT) for Iranian migrants suffering from major depressive disorder (MDD) and living in Austria for an average of 14 years. The qualitative data were collected through interviews based on the Farsi version of the Structured Clinical Interview for the fourth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV). However, to obtain more information from the participants, they were asked to talk in more detail about their childhood and teenage years, reasons for immigration, their lifestyle before and after immigration, and their social activities. Interviews were conducted at four time points: preintervention, postintervention, 1-month follow-up, and 6-month follow-up. Patients who did not complete the interventions were interviewed on a voluntary basis to explain their reasons. Preintervention interviews were conducted to get some useful information about participant's' expectations of psychotherapy, especially group-based cognitive-behavioral therapy (GCBT), and also to assess the reasons for depression from their own point of view. The postintervention interviews were conducted to examine the participants' psychological situations as well as the reasons for positive effects of interventions. The interviews on average lasted 50 minutes, and field notes were taken. The results of this study showed a reduction in depression symptoms after the interventions. However, the effect of treatment was not persistent. The findings suggest that the main reasons behind Iranian migrants' depression in Austria is related to their dysfunctional acculturation attitude. The effectiveness of GCBT for Iranian migrants with depression also may be related to their sociocultural background. PMID:27294588

    A major challenge for modern waste management lies in a smart integration of waste-to-energy installations in local energy systems in such a way that the energy efficiency of the waste-to-energy plant is optimized and that the energy contained in the waste is, therefore, optimally utilized. The extent of integration of thermal waste treatment processes into regular energy supply systems plays a major role with regard to climate control. In this research, the specific waste management situation looked at scenarios aiming at maximizing the energy recovery from waste (i.e. actual scenario and waste-to-energy process with 75% energy efficiency [22.5% electricity, 52.5% heat]) yield greenhouse gas emission savings due to the fact that more greenhouse gas emissions are avoided in the energy sector than caused by the various waste treatment processes. Comparing dedicated waste-to-energy-systems based on the combined heat and power (CHP) process with concepts based on sole electricity production, the energy efficiency proves to be crucial with regard to climate control. This underlines the importance of choosing appropriate sites for waste-to-energy-plants. This research was looking at the effect with regard to the climate impact of various waste management scenarios that could be applied alternatively by a private waste management company in Austria. The research is, therefore, based on a specific set of data for the waste streams looked at (waste characteristics, logistics needed, etc.). Furthermore, the investigated scenarios have been defined based on the actual available alternatives with regard to the usage of treatment plants for this specific company. The standard scenarios for identifying climate impact implications due to energy recovery from waste are based on the respective marginal energy data for the power and heat generation facilities/industrial processes in Austria.

  16. Effects of acculturative stress on PTSD, depressive, and anxiety symptoms among refugees resettled in Australia and Austria

    2016-01-01

    Background Research indicates that exposure to war-related traumatic events impacts on the mental health of refugees and leads to higher rates of posttraumatic stress disorder (PTSD), depression, and anxiety symptoms. Furthermore, stress associated with the migration process has also been shown to impact negatively on refugees' mental health, but the extent of these experiences is highly debatable as the relationships between traumatic events, migration, and mental health outcomes are complex and poorly understood. Objective This study aimed to examine the influence of trauma-related and post-migratory factors on symptoms of PTSD, depression, and anxiety in two samples of Bosnian refugees that have resettled in two different host nations—Austria and Australia. Method Using multiple recruitment methods, 138 participants were recruited to complete self-report measures assessing acculturative stress, PTSD, depressive, and anxiety symptoms. Results Hierarchical regressions indicated that after controlling for age, sex, and exposure to traumatic events, acculturative stress associated with post-migratory experiences predicted severity of PTSD and anxiety symptoms, while depressive symptoms were only predicted by exposure to traumatic events. This model, however, was only significant for Bosnian refugees resettled in Austria, as PTSD, depressive, and anxiety symptoms were only predicted by traumatic exposure in the Bosnian refugees resettled in Australia. Conclusion These findings point toward the importance of assessing both psychological and social stressors when assessing mental health of refugees. Furthermore, these results draw attention to the influence of the host society on post-migratory adaptation and mental health of refugees. Further research is needed to replicate these findings among other refugee samples in other host nations. PMID:26886488

    Usutu virus (USUV), family Flaviviridae, has been responsible for avian mortality in Austria from 2001 to 2006. The proportion of USUV-positive individuals among the investigated dead birds decreased dramatically after 2004. To test the hypothesis that establishment of herd immunity might be responsible, serological examinations of susceptible wild birds were performed. Blood samples of 442 wild birds of 55 species were collected in 4 consecutive years (2003--2006). In addition, 86 individuals from a birds of prey rehabilitation centre were bled before, at the peak, and after the 2005 USUV transmission season in order to identify titre dynamics and seroconversions. The haemagglutination inhibition test was used for screening and the plaque reduction neutralization test for confirmation. While in the years 2003 and 2004 the proportion of seropositive wild birds was <10%, the percentage of seroreactors raised to >50% in 2005 and 2006. At the birds of prey centre, almost three quarters of the owls and raptors exhibited antibodies before the 2005 transmission season; this percentage dropped to less than half at the peak of USUV transmission and raised again to almost two thirds after the transmission season. These data show a from year to year continuously increasing proportion of seropositive wild birds. The owl and raptor data indicate significant viral exposure in the previous season(s), but also a number of new infections during the current season, despite the presence of antibodies in some of these birds. Herd immunity is a possible explanation for the significant decrease in USUV-associated bird mortalities in Austria during the recent years. PMID:17869454

  18. Application of 2-D geoelectrical resistivity tomography for mountain permafrost detection in sporadic permafrost environments: Experiences from Eastern Austria

    2015-04-01

    Mountain permafrost covers some 2000 km² of the Austrian Alps which is less than 2.5% of the national territory. Delineating the altitudinal lower limit of permafrost in the mountains of Austria is difficult due the complex topography, the rather sparseness of field verification data and the lack of long-term permafrost monitoring data. Such monitoring data should cover different slope aspects, different elevations, different substrates and different mountain regions of Austria. In this study it was attempted to delineate the lower limit of permafrost at two study sites in the Tauern Range, Austria, applying two-dimensional geoelectrical resistivity tomography (ERT). In addition, multi-annual ground temperature data collected by miniature temperature datalogger (MDT) were used to validate the results. At the study site Hochreichart (maximum elevation 2416 m asl), located in the Seckauer Tauern Range, 14 ERT profiles (lengths 48-196 m; electrode spacing 2, 2.5 or 4 m) were measured at elevations between 1805 and 2416 m asl. Measurements were carried out at two cirques (Reichart, Schöneben) and at the summit plateau of Hochreichart. Results at this site indicate that permafrost lenses are detectable at elevations down to c.1900 m asl at radiation-sheltered sites. Furthermore, at the summit plateau permafrost only occurs as rather small lenses. The ERT-based permafrost pattern is generally confirmed by the MTD data with negative mean annual ground temperature values at only a few monitoring sites. However, the possibility of air-filled cavities causing higher resistive zones faking permafrost existence cannot be excluded because coarse-grained sediments (i.e. relict rock glaciers and autochthonous block fields) are widespread at this study site. At the second study site Kögele Cirque (maximum elevation 3030 m asl) located in the Schober Mountains 12 ERT profiles (lengths 48 m; electrode spacing 2 m) were measured at elevations between 2631 and 2740 m asl.

The antibiotic susceptibility of 274 MRSA and 284 MSSA strains from Hungary, Austria and macedonia was tested by the broth microdilution method. The clonal relationship of strains was determined by pulsed-field gel electrophoresis. Intermediate susceptibility to vancomycin appeared in Macedonian MRSA strains. Macedonian MRSA strains had high-level amikacin and gentamicin resistance. MSSA strains generally were susceptible to all drugs at minimum inhibitory concentrations (MIC(50)) except for gentamicin resistance in Macedonian strains. In Hungary and Austria a common antibiotic resistance phenotype of MRSA predominated, while in macedonia three other phenotypes were also prevalent. Geographical differences in the resistance of S. aureus are still high. Since resistance levels of MRSA and MSSA strains differ extensively, they should be considered separately for antibiotic resistance analysis.

    The protozoan Hepatozoon canis, which is transmitted via ingestion of infected ticks by canine hosts, is not endemic to mid-latitude regions in Europe. Its distribution is supposed to be linked to the occurrence of its primary tick vector Rhipicephalus sanguineus. A young male golden jackal (Canis aureus) found as road kill close to Vienna, Austria, was infected by this pathogen. Cloning and sequencing of the PCR product revealed 6 different haplotypes of H. canis. Based on the sequences, no clear relationship to the origin of infection could be traced. This is the first report of H. canis for Austria, and wild canines such as the currently found jackal may provide a source of natural spread of this parasite into non-endemic areas. This natural immigration of wild animals represents a way of pathogen introduction, which has to be considered in disease prevention in addition to human-made introduction due to animal import and export.

    The scleractinian genus Faksephyllia Floris, 1972, is revised based on the study of original and topotypic material as well as original descriptions. Representatives of this genus have been reported from only a small number of lower Paleogene localities, including the Danian of Azerbaijan, Denmark (Greenland), Kazakhstan, and Sweden, as well as the Paleocene of Austria and Denmark (Fakse). New material belonging to the type species of Faksephyllia (F. faxoensis) is described from the Lower Oligocene of Austria (Northern Calcareous Alps, Tyrol). In addition, material from the Oligocene of Germany and the Lower Oligocene of Italy, formerly grouped with the genera Calamophyllia and Rhabdophyllia, are here re-assigned and transferred to Faksephyllia. The genus Faksephyllia remains a monospecific taxon, including only the type species, Faksephyllia faxoensis (Beck, in Lyell). In addition, Faksephyllia represents the earliest colonial genus among the caryophylliids. PMID:27615857

    Laurelia Juss. (Atherospermataceae R. Br.) today is a disjunct genus in the southern hemisphere that inhabit temperate moist forests of South America and New Zealand. Unequivocal Atherospermataceae fossils are still rare and are known since the Upper Cretaceous from the southern hemisphere. Here, we present the first findings of Laurelia pollen in the northern hemisphere, preserved in EECO (Early Eocene Climate Optimum) sediments in southern Austria. The sediments of the Paleogene Holzer Formation rest with an erosional unconformity on Campanian rocks, is 8 m-thick and composed of soft red and green claystone, and coaly lenses rich in terrestrial palynomorphs. The pollen and spores were examined with LM and SEM and assigned to botanical families and genera. Overall, three different palynomorph-rich facies were identified: The first, at the base of the Holzer Formation, is characterized by abundant and diverse fern spores, various Arecaceae, Myricaceae, and Juglandaceae. The second is from the black transgressive shale and characterized by the co-occurrence of marine dinoflagellates and Normapolles, Nypa, palm pollen, and Avicennia. The third facies is dominated by wind pollinated triporate taxa (e.g., Normapolles, Myricaceae, Juglandaceae), monosulcate palm taxa and numerous fern spores. The Atherospermataceae pollen, which resembles most closely the genus Laurelia Juss., were encountered in low numbers in all three facies of the Holzer Formation, but previously misidentified. The reason lies in the aperture type: Atherospermataceae pollen are composed of two hemispherical halves that are separated by a complete ring-like aperture or an incomplete a ring-like aperture that acts as a zone of weakness so that the deposited fossil pollen, tend to fall apart. Most fossil Laurelia pollen in the Krappfeld are preserved as rolled up individual halves and look like boat-shaped sulcate pollen grains of monocots or basal angiosperms; preservation of complete grains is rare

    In AQA, Air Quality model for Austria, the regional weather forecast model ALADIN-Austria of the Central Institute for Meteorology and Geodynamics (ZAMG) is used in combination with the chemical transport model CAMx (www.camx.com) to conduct forecasts of gaseous and particulate air pollutants over Austria. The forecasts which are done in cooperation with the University of Natural Resources and Applied Life Sciences in Vienna (BOKU) are supported by the regional governments since 2005. In the current model version AQA uses the operational meteorological forecasts conducted with ALADIN which has a horizontal resolution of 9.7 km. Since 2008 the higher resolved ALARO is also available at the ZAMG. It has a horizontal resolution of 4.9 km and models the PBL with more vertical layers than ALADIN. ALARO also uses more complex algorithms to calculate precipitation, radiation and TKE. Another advantage of ALARO concerning the chemical modelling with CAMx is that additionally to the higher resolved meteorological forecasts it is possible to use finer emission inventories which are available for Austria. From 2006 to 2007 a SODAR-RASS of the ZAMG was operated in the north-eastern Austrian flat lands (Kittsee). In this study the measured vertical profiles of wind and temperature are compared with the model predictions. The evaluation is conducted for an episode in January 2007 when high PM10 concentrations were measured at the air quality station Kittsee. Analysis of the RASS-temperature-profiles show that during this episode a strong nocturnal inversion developed at the investigated area. The ability of the models ALADIN and ALARO to predict this complex meteorological condition is investigated. Both models are also used as meteorological driver for the chemical dispersion model CAMx and the results of predicted PM10 concentrations are compared to air quality measurements.

    The AGO Kommission Ovar already published a statement in 2013, warning about the uncritical use of hyperthermic intraperitoneal chemotherapy (HIPEC) outside controlled studies. This statement has now been updated after the most recent literature was reviewed by AGO Kommission Ovar, the AGO Study Group, NOGGO, AGO Austria and AGO Switzerland. The authors conclude that HIPEC remains experimental. Its use is not recommended and should be rejected outside of prospective controlled trials. PMID:26941446

    Biogas is rich in methane and can be further purified through biogas upgrading technologies, presenting a viable alternative to natural gas. Landfills and anaerobic digestors treating municipal solid waste are a large source of such biogas. They therefore offer an attractive opportunity to tap into this potential source of natural gas while at the same time minimizing the global warming impact resulting from methane emissions in waste management schemes (WMS) and fossil fuel consumption reduction. This study looks at the current municipal solid waste flows of Spain, Italy, and Austria over one year (2009), in order to determine how much biogas is generated. Then it examines how much natural gas could be substituted by using four different biogas upgrading technologies. Based on current waste generation rates, exploratory but realistic WMS were created for each country in order to maximize biogas production and potential for natural gas substitution. It was found that the potential substitution of natural gas by biogas resulting from the current WMS seems rather insignificant: 0.2% for Austria, 0.6% for Italy and 0.3% for Spain. However, if the WMS is redesigned to maximize biogas production, these figures can increase to 0.7% for Austria, 1% for Italy and 2% for Spain. Furthermore, the potential CO2 reduction as a consequence of capturing the biogas and replacing fossil fuel can result in up to a 93% reduction of the annual national waste greenhouse gas emissions of Spain and Italy.

    The emergence of West Nile virus (WNV) was expected in Austria since the initial discovery of the infection in neighbouring Hungary in 2003/2004. In 2008 six cases of West Nile disease were diagnosed at the Institute for Veterinary Disease Control Mödling, Austrian Agency for Health and Food Safety (AGES), involving five goshawks (Accipiter gentilis) and one gyrfalcon (Falco rusticolus), which were found dead in the eastern Austrian federal states of Lower Austria, Vienna and Styria, respectively. Pathomorphological and immunohistochemical findings suggested a WNV infection. Virus was isolated in embryonated specific pathogen free chicken eggs and propagated in mouse neuroblastoma cells (NA), in which a cytopathic effect occurred. The virus was identified and characterised by electron microscopic examination and molecular detection using RT-PCR, sequencing, and phylogenetic analysis. The Austrian WNV sequences exhibited nucleotide identities of 99.9% to the lineage 2 WNV sequences described in Hungary since 2004. In addition, 71 sera of 14 different bird species were screened for the presence of WNV antibodies using a commercial ELISA: 43.7% of the tested samples showed antibody titers. Selected positive sera were also subjected to WNV neutralisation tests, in which the ELISA results were verified in 66%. The results of this study confirm unambiguously the presence of a lineage 2 WNV infection in birds of prey in the eastern part of Austria.

    A critical discussion of the recent First Section and Grand Chamber judgments of the European Court of Human Rights in the case of S.H. and Others v. Austria, which upheld an Austrian ban on in-vitro fertilisation (IVF) using donor gametes (ova and sperm). The author argues that the regulatory regime adopted by Austria is overbroad insofar as the regime it adopts fails to accurately reflect the legitimate interests of the state. This is not a conventional "controversial morals" case where, in the absence of a clear moral and/or policy consensus among the Council of Europe member states, states are properly accorded a wide margin of appreciation. The regime adopted by Austria embodies a clear sex bias (with their respective gametes standing as near perfect proxies for the sex of the applicants) with exceptions being made to address male infertility while leaving women without medical remedy. As such, the margin of appreciation should be significantly restricted and the classifications embodied by the regime subject to the highest possible scrutiny.

    Antibiotic resistance patterns of more than 120 000 clinical Escherichia coli isolates were retrospectively analysed. Isolates originated from both hospitalized patients and outpatients from the region of southeast Austria from 1998 to 2013. Except for amoxicillin/clavulanic acid, nitrofurantoin and piperacillin/tazobactam, all of the antibiotics analysed showed increasing proportions of resistant isolates over time, which were most prominent for ampicillin (from 25.4% in 1998 to 40% in 2013), cefotaxime (0.1% to 6.7%), ceftazidime (0.3% to 14.2%), ciprofloxacin (4.3% to 16.7%) and trimethoprim/sulfamethoxazole (14.6% to 24.8%). There was a marked increase in extended-spectrum β-lactamase-positive isolates (0.1% to 6.3%) starting in 2005, with male patients and hospital-related patients showing a higher increase than female patients and outpatients. Proportions of resistant isolates for most antibiotics were generally higher for male patients and hospital-related patients. Amikacin, nitrofurantoin and trimethoprim/sulfamethoxazole showed a marked increase in resistance proportions among male subjects aged 10 to 19 years which were absent for female subjects, indicating a strong modulation potential of host characteristics.

    Global warming results in an ongoing retreat of glaciers in the Alps, leaving behind large amounts of easily erodible sediments. In addition, the debuttressing of rock-walls and the decay of permafrost in the high mountain regions facilitates mass movements of potential disastrous consequences, such as rock falls, landslides and debris flows. Therefore, it is highly important to quantify the amount of sediments that are supplied from the different compartments and to investigate how glacial retreat influences sediment dynamics in proglacial areas. In the presented work glacier retreat and associated sediment dynamics were investigated in the Kromer valley (Silvretta Alps, Austria) by analyzing remote sensing data. Glacial retreat from the period of 1950 to 2012 was documented by interpreting aerial photographs. By digitizing the different stages of the glaciers for six time frames, changes in glacier area and length were mapped and quantified. In order to identify, characterize and quantify sediment dynamics in the proglacial areas a high resolution DEM of difference (DoD) between 2007 and 2012 was created and analyzed, further differentiating between different zones (e.g. valley bottom, hillslope) and types of geomorphic processes (e.g. fluvial, gravitational). First results will be presented at the EGU General Assembly 2016.

    Traditional bilingual education programmes in regional linguistic minority contexts face major challenges within the recent paradigm of linguistic diversity against a background of increasing migration, mobility and trans-locality. Based on three case studies, the authors of this paper focus on how particular dual-medium models are applied in Slovene-German schools in Carinthia, Austria. They examine not only how these schools provide for a balanced bilingual teaching and learning environment, but also how they deal with their students' multilingual realities and support their identification with bi- and multilingualism. The authors regard schools as institutional sites where linguistic dispositions are subject to discursive power relations and where language policies and educational goals are negotiated by teachers, parents and students alike. Drawing on speaker-centred and ethnographic approaches in sociolinguistic research, the authors seek to document experiences of all actors involved as well as spatial and discursive practices. Through this the authors show how these dual-medium schools achieve particular profiles in multilingual education which are potentially regarded as innovative examples of best-practice and as being of interest for students and families with heterogeneous linguistic backgrounds.

    Worldwide, countries face the challenge of securing funds for health promotion. To address this issue, some governments have established health promotion foundations, which are statutory bodies with long-term and recurrent public resources. This article draws on experiences from Austria, Australia, Germany, Hungary and Switzerland to illustrate four lessons learned from the foundation model to secure funding for health promotion. These lessons are concerned with: (i) the broad spectrum of potential revenue sources for health promotion foundations within national contexts; (ii) legislative anchoring of foundation revenues as a base for financial sustainability; (iii) co-financing as a means to increase funds and shared commitment for health promotion; (iv) complementarity of foundations to existing funding. Synthesizing the lessons, we discuss health promotion foundations in relation to wider concerns for investment in health based on the values of sustainability, solidarity and stewardship. We recommend policy-makers and researchers take notice of health promotion foundations as an alternative model for securing funds for health promotion, and appreciate their potential for integrating inter-sectoral revenue collection and inter-sectoral funding strategies. However, health promotion foundations are not a magic bullet. They also pose challenges to coordination and public sector stewardship. Therefore, health promotion foundations will need to act in concert with other governance instruments as part of a wider societal agenda for investment in health.

  14. Enabling eParticipation of the Youth in the Public Debate on Legislation in Austria: A Critical Reflection

    Scherer, Sabrina; Neuroth, Christoph; Schefbeck, Günther; Wimmer, Maria A.

    Legislation formation is an area of democracy, in which participation of target groups (citizens, companies, interest groups, experts) plays a crucial role. With the emergence of the Internet and the growing maturity of more recent technologies a new potential emerged for supporting participation in the legislation process. The use of ICT does, however, not automatically enhance the participation in democratic processes and may even impose new [technically based] barriers. Therefore, software development of legislative eParticipation applications should carefully investigate and bear in mind the specific targeted users. It is not feasible to just provide the necessary ICT and the legislative documents in order to start a consultation, especially with young citizens. When introducing not only a new tool but even a new procedure, the whole process needs to be planned in detail and accompanied by an expert team. In this respect, the paper at hand describes the implementation of a pilot within the LEX-IS project that aimed to facilitate and enable participation of the youth in the public debate on legislation in Austria. The subject of online discussion via the platform was a ministerial draft bill and the formulation of a comment statement based on the previous discussions to be uploaded on the Austrian Parliament’s platform. The paper introduces the evaluation methodology and the results of the pilot regarding the use of the argumentation support system, participation of the youth and potential impact on the Austrian legislature. Finally, concluding remarks are provided.

    Total and size-segregated Pt and Pd emission factors from on-road vehicles were measured in the Kaisermühlen Tunnel in Vienna, Austria. Aerosol sampling was performed simultaneously inside and outside the tunnel during April and May 2005. Analysis of the acid-digested aerosol samples was performed using a preconcentration procedure with subsequent on-line detection by electro-thermal atomic absorption spectrometry (ETAAS). Inside the tunnel distinctly increased Pt and Pd concentrations were found with highest levels in total suspended particulate matter samples and reduced concentrations in the size-segregated PM10 and PM2.5 samples. Emission factors were calculated from concentration differences between tunnel inside and tunnel outside samples, the distance between tunnel entrance and sampling location, the ventilation rate, and the number of vehicles passing through the tunnel. Emission rates observed for Pt ranged from 38 +/- 5.9 to 146 +/- 13 ng veh(-1) km(-1), whereas the emission factors of Pd varied between 13 +/- 2.1 and 42 +/- 4.1 ng veh(-1) km(-1). Variations in the emission rates were assumed to originate from alterations in traffic conditions. Size-segregated investigations revealed that the major part of Pt and Pd emissions were released in the coarse aerosol mode (size fraction > PM10), nevertheless a considerable fraction (approximately 12% and approximately 22% respectively) was emitted in the inhalable PM2.5 fraction.

    The impact of air mass origin and season on aerosol chemical composition and new particle formation and growth events (NPF events) in Vienna, Austria, is investigated using impactor samples from short-term campaigns and two long-term number size distribution datasets. The results suggest that air mass origin is most important for bulk PM concentrations, chemical composition of the coarse fraction (>1.5 μm) and the mass size distribution, and less important for chemical composition of the fine fraction (<1.5 μm). Continental air masses (crustal elements) were distinguished from air masses of marine origin (traces of sea salt). NPF events were most frequent in summer (22% of measurement days), and least frequent in winter (3% of measurement days). They were associated with above-average solar radiation and ozone concentrations, but were largely independent of PM2.5. Air mass origin was a secondary influence on NPF, largely through its association with meteorological conditions. Neither a strong dependence on the PM2.5 loading of the air masses, nor indications of a source area for NPF precursors outside the city were found.

    In Austria, mandatory screening for the prevention of congenital toxoplasmosis stipulates a serological test for antibodies against Toxoplasma gondii as early as possible in pregnancy. In the case of a seronegative result, subsequent tests at intervals of 8 weeks are requested. We analysed serological data from Styria, an Austrian federal state, to determine the seroprevalence and incidence of Toxoplasma infections. The study included 353,599 tests from 103,316 women during 158,571 pregnancies from 1995 to 2012. The age-adjusted seroprevalence decreased from 43.3% in 1995 to 31.5% in 2012, with a yearly decline of 0.84% (95% confidence interval (CI): 0. 79 -0.88). The intergravid incidence showed an annual decrease of 4.2%. The average yearly incidence of intragravid and intergravid seroconversions was 0.52% (95% CI 0.45–0.61) and 0.72% (95% CI 0.67–0.77), respectively. If the difference between these rates (p < 0.001) can be explained by the effect of primary prevention such as avoiding raw meat and taking hygiene precautions when encountering cats or preparing vegetables, only ca two of seven (28%) infections were avoided by hygiene measures taken by pregnant women. Primary prevention may therefore have its limits. PMID:27562876

    Water protection is one of the most important goals in environmental protection. The Clean Water Act in the USA and the Water Framework Directive (WFD) in Europe are the legal frameworks to facilitate the achievement of this goal. The question is raised of whether more information can be extracted from WFD-related groundwater data. To answer it, a methodology has been developed that is easy to use and could be implemented into official practice. A case study is presented in which the groundwater data of a sodic area in Austria (Seewinkel) is assessed. Eighteen parameters in groundwater sampled from 23 wells (1991-2011) were analyzed. With basic statistics, trend-, cluster-, Wilks' λ and spatial sampling density analysis, local phosphorus and boron phenomena were described, along with the determining role of sulphate, groundwater flow, and the oxygen gradient in the area. As a final step, the spatial sampling density was determined. Regarding the current set of parameters, all the sampling sites are necessary and only in the case of certain parameters (Ca2+, Mg2+, K+, NO3 -, pH) could one sampling site be abandoned. The methodology applied brings a new perspective to exploring groundwater data collected according to the requirements of the WFD.

    The mineral chemistry of heavy minerals has been widely used to identify, discriminate, and characterise sediment source areas. In particular, the heavy mineral garnet has important implications for the identification of the potential lithologies exposed in the source area(s) and their evolution through time because it has a wide range of major element composition and of its high importance in defining metamorphic conditions. We sampled stream sediments and adjacent source-rocks in the southern Tauern window of the central Eastern Alps in Austria. The Tauern window exposes an old continental basement belonging to the European foreland. Our study area encompasses metamorphic rocks in the Dorfertal, Timmeltal and Frosnitztal valleys, and accompanying sediments from recent rivers. Heavy mineral assemblages and major element composition of garnets are used to study the source to sink relations. The studied rivers are draining the same geological (well-defined) source area (i.e. Venediger nappe, Eclogite zone, Glockner nappe). In our research, we like to answer following question: Do the recent river sediments show similar heavy mineral suites and garnet composition compared with those present in the source rocks?

    The dependency on carbon-based fossil energy and growing awareness of climate change issues has induced ambitious policy initiatives to promote renewable energy sources for indoor heating. Combustion of regionally available material such as wood is considered a carbon-neutral alternative for oil and gas, but unregulated revival of wood stoves may cause detrimental health effects. For the prognosis of the health impact of air pollution due to the use of wood stoves, Upper Austria served for a case study. On the basis of recent measurements of particulate matter <10 μm in aerodynamic diameter (PM10) and nitrous gases (NO(x)), we compared the air pollution attributable to present energy mix (termed scenario 1) with two alternatives: For scenario 2, we assumed replacement of light fuel oil by either fossil gas or biomass, and for scenario 3, replacement of light fuel oil by biomass only. Compared with the current exposure from scenario 1, the increased annual mean PM10 levels are estimated to lead to 101 (95% CI 56;146) and 174 (95% CI 92;257) additional deaths among 1.4 million inhabitants per year for scenarios 2 and 3, respectively. Without adequate strategies for reducing the emissions of domestic heating facilities, replacement of fossil energy sources could lead to an increased health risk.

    The dependency on carbon-based fossil energy and growing awareness of climate change issues has induced ambitious policy initiatives to promote renewable energy sources for indoor heating. Combustion of regionally available material such as wood is considered a carbon-neutral alternative for oil and gas, but unregulated revival of wood stoves may cause detrimental health effects. For the prognosis of the health impact of air pollution due to the use of wood stoves, Upper Austria served for a case study.

    We performed a 6-month open-label study on the use of the transdermal rivastigmine patch in clinical routine in 103 patients with Alzheimer's disease from 25 outpatient services in Austria. After baseline, safety and tolerability of the 10 cm2--rivastigmine patch was assessed at week 4, 12 and 24 in all patients. A Mini Mental State Examination was done at baseline and at week 12 and 24. Skin adherence of the patch was very good or good in 85% of study participants. Only 2.9% of patients had gastrointestinal adverse events. Local skin reactions occurred in 23% of individuals. Skin alteration were mostly mild in severity. In only 6.8% of subjects did they result in termination of treatment. At the earliest skin reactions were observed after 3 months of treatment. Cognitive functioning of patients improved comparable to the controlled trial which led to approval of the rivastigmine patch. In daily routine the safety profile of the rivastigmine patch is favourable, as is the response to treatment. Local, mostly mild skin reactions affect approximately every fifth patient, and they occur relatively late in the course of therapy. Patients and their caregivers should receive detailed information about skin reactions to omit unnecessary drop outs to treatment. PMID:19272293

    Immunohistochemical, ultrastructural and pathological studies were carried out on the gills of bream Abramis brama (L.) from Lake Mondsee, Austria, that were naturally infected with Ergasilus sieboldi Nordmann, 1832. Of a total of 14 specimens of bream examined, the gills of 7 (50%) were parasitized with this copepod and the intensity of infection ranged from 1 to 23 crustaceans per host. Histopathological investigations of infected gill showed extensive tissue damage due to attachment and feeding of the crustacean. Parasites attached close to the base of filaments near the gill arch. Pressure exerted by the ectoparasite attached to the lateral margin of the gill filaments induced atrophy of the secondary lamellae. Tissue reactions included hyperplasia and mucous cell proliferation of the respiratory epithelium. Mucous cells displayed an intense immunohistochemical reactivity with the anti-nitric oxide synthase antibody. In parasitized primary and secondary lamellae, a high number of eosinophilic granular cells and rodlet cells were noticed. Rodlet cells represent an inflammatory cell type closely linked to other piscine inflammatory cells. Presence of a high number of inflammatory cells at the site of E. sieboldi attachment is related to intense host cellular reaction.

    Geomorphological landslide inventories provide crucial input data for any study on the assessment of landslide susceptibility, hazard or risk. Several approaches for assessing landslide susceptibility have been proposed to identify areas particularly vulnerable to this natural hazard. What they have in common is the need for data of observed landslides. Therefore the first step of any study on landslide susceptibility is usually the compilation of a geomorphological landslide inventory using a geographical information system. Recent research has proved the feasibility of orthophoto interpretation for the preparation of an inventory aimed at the delineation of landslides with the use of distinctive signs in the imagery data. In this study a multi-annual landslide inventory focusing on shallow landslides (i.e. translational soil slides of 0-2 m in depth) was compiled for two study areas in Vorarlberg (Austria) from the interpretation of nine orthophoto series. In addition, derivatives of two generations of airborne laser scanning data aided the mapping procedure. Landslide scar areas were delineated on the basis of a high-resolution differential digital terrain model. The derivation of landslide volumes, depths and depth-to-length ratios are discussed. Results show that most mapped landslides meet the definition of a shallow landslide. The inventory therefore provides the data basis for the assessment of shallow landslide susceptibility and allows for the application of various modelling techniques.

    J. N. Cooley, manager, Safeguards Studies Department; E. Von Halle, head, Technical Resources Section; and D. W. Swindle, Jr., director, International Technology Programs Division, Martin Marietta Energy Systems, Inc., traveled to Vienna, Austria, November 9--20, 1988, to conduct a 5-day uranium enrichment safeguards training course for the International Atomic Energy Agency (IAEA). The course was developed and conducted by Energy Systems for the IAEA through the US. Program for Technical Assistance to IAEA Safeguards (POTAS) under Task B.48. Titled ''Nuclear Material Safeguards for Enrichment Plants,'' this second session of the course was held on November 14--18, 1988, for 15 IAEA inspectorate and support division personnel. The course was developed and initially taught in 1987 to train IAEA professionals whose responsibilities require knowledge of safeguarding nuclear material at enrichment plants on the safeguards-relevant principles of enrichment technology, particularly as related to centrifuge enrichment facilities. Based on comments received during initial training session, the course and reference materials were revised, updated, and expanded. The main objective of the course is to provide participants with the necessary skills to perform their inspection activities at enrichment plants. Overall, the course was very well received; the four-part course manual was especially appreciated because of the text accompanying the view graphs. The general consensus was that the course should be repeated so that inspectors who could not be accommodated in this session will have a chance to be trained in this important area of safeguards.

    Multihazard risk analysis and disaster planning for emergency services as a basis for efficient provision in the case of natural hazards - case study municipality of Au, Austria A. Maltzkait (1) & C. Pfurtscheller (1) (1) Institute for Interdisciplinary Mountain Research (IGF), Austrian Academy of Sciences, Innsbruck, Austria The extreme flood events of 2002, 2005 and 2013 in Austria underlined the importance of local emergency services being able to withstand and reduce the adverse impacts of natural hazards. Although for legal reasons municipal emergency and crisis management plans exist in Austria, they mostly do not cover risk analyses of natural hazards - a sound, comparable assessment to identify and evaluate risks. Moreover, total losses and operational emergencies triggered by natural hazards have increased in recent decades. Given sparse public funds, objective budget decisions are needed to ensure the efficient provision of operating resources, like personnel, vehicles and equipment in the case of natural hazards. We present a case study of the municipality of Au, Austria, which was hardly affected during the 2005 floods. Our approach is primarily based on a qualitative risk analysis, combining existing hazard plans, GIS data, field mapping and data on operational efforts of the fire departments. The risk analysis includes a map of phenomena discussed in a workshop with local experts and a list of risks as well as a risk matrix prepared at that workshop. On the basis for the exact requirements for technical and non-technical mitigation measures for each natural hazard risk were analysed in close collaboration with members of the municipal operation control and members of the local emergency services (fire brigade, Red Cross). The measures includes warning, evacuation and, technical interventions with heavy equipment and personnel. These results are used, first, to improve the municipal emergency and crisis management plan by providing a risk map, and a

    About 2.5% (~2000 km²) of the national territory of Austria is influenced by permafrost conditions. A slightly smaller area of Austria is additionally affected by deep seasonal frost which is, however, similarly exposed to intensive physical weathering and related geomorphic processes. Currently, 23 skiing resorts, 31 water reservoirs and 42 mountain huts are either directly or indirectly influenced by permafrost and associated processes in Austria as determined from regional permafrost models. Ground thermal changes most likely affect the ground stability and infrastructure in those areas. Therefore, changes in the distribution and characteristics of permafrost and seasonal frost are of high economic and ecological importance. A range of Austrian institutions are interested in systematic permafrost monitoring (several universities, geological surveys, the Austrian torrent and avalanche control agency or several different alpine clubs). However, to date no coordinated monitoring network has been established on a national scale and a strategy for long-term permafrost/periglacial observation did not exist so far. Such a national strategy has been developed in 2015 within the permAT project funded through the StartClim2014-program. During permAT an extensive literature review and data search as well as a workshop with 40 participants (scientists, stakeholder and policy maker) were accomplished. The workshop allowed the integration of national as well as international colleagues into the strategy development. Results of permAT clearly demonstrate that the number of present permafrost/periglacial monitoring sites is far too little in Austria. Only few alpine areas of Austria are well represented by the existing monitoring activities but large areas lack such instrumentations. Furthermore, permafrost boreholes exist at only three sites in central Austria (all contribution to the GTN-P network) and there is a lack of knowledge about thermal conditions and recent changes

    The isotopic ratios of oxygen and hydrogen in water (2H/1H and 18O/16O) are important tools to characterise waters and their cycles. This starts in the atmosphere as rain or snow and continues in surface water and ends in shallow groundwater as well as in deep groundwater. Tritium formed by natural cosmic radiation in the upper atmosphere and in the last century by tests of thermonuclear bombs in the atmosphere, is characterised by its radioactive decay with a half-life of 12.32 years and is an ideal age-marker during the last 60 years. To determine the origin and mean age of waters in many projects concerning water supply, engineering and scientific projects in the last 45 years on more than 1,350 sites, more than 40,000 isotope measurements were performed in Austria. The median value of all sites of oxygen-18 is δ 18O -10.7 ‰ and for hydrogen-2 δ 2H -75 ‰. As the fractionation is mainly temperature dependent the lowest negative values are observed in winter precipitation (oxygen-18 as low as δ 18O -23 ‰) and in springs in the mountain regions (δ 18O -15.1 ‰). In contrast the highest values were observed in summer precipitation (up to δ 18O - 0.5 ‰) and in shallow lakes in the Seewinkel (up to δ 18O + 5 ‰). The isotopic ratios of the Austrian waters are also influenced by the origin of the evaporated water masses. Therefore the precipitation in the region south of the main Alpine crest (East-Tyrol, Carinthia and South-East Styria) is approximately 1 ‰ higher in δ 18O-values than sites at the same altitude in the northern part. This is most probably caused by the stronger influence of precipitation from the mediterranean area. The median value of all 1,120 sampling sites of decay corrected (2015) tritium measurements is 6.2 tritium units (TU). This is somewhat smaller than the median value of all precipitation stations with 7.2 TU. This can be explained by the fact that in most cases in groundwater the median value has been reduced by decay

    INTRODUCTION: In a village situated at 1215 m a.s.l. in a natural preserve in an Austrian alpine valley elevated BaP concentrations have been measured in the last years. A highly frequented highway leading from Italy to Germany passes near the village. Monthly means of particulate BaP concentrations show a clear seasonal trend with values below 1 ng/m³ during the warmer months and with concentrations up to 9 ng/m³ in the cold season. Annual averages in the years 2000 - 2005 ranged between 1.4 and 2.8 ng/m³ - much higher than the EU target value of 1 ng/m³. We used a macrotracer model developed at the Vienna University of Technology to determine the contributions of the sources for BaP emissions, which were mainly space heating with wood and traffic from the highway. EXPERIMENTAL: The macrotracer concept is a nine component model to derive source contribution and explains 80-100% of PM10 aerosols in Austria. The amount of traffic exhaust is derived by using EC as tracer, whereas EC produced by wood burning is subtracted, the amount of wood smoke is derived by the anhydro-sugar levoglucosan and the ratio between the anhydro-sugars levoglucosan and mannosan. For the source apportionment of BaP the applied factors reflect on the one hand the composition of the automotive fleet in Austria and on the other hand the composition of the fire wood in the region. Filter samples collected with a high volume sampler in winter were analyzed for PM10 aerosol mass, total, organic, elemental and carbonate carbon, HULIS, anhydro-sugars, polyols and ions (major ions and organic acids) and PAHs. In the same way emission samples taken at a motor test stand and at a test stand for wood combustion were analyzed (Schmidl et al. 2008). The saccharides were determined using high pH anion exchange and pulsed amperometry (HPAE-PAD). Details of the analytical method are given in Iinuma et al., 2009. Elemental and organic carbon were determined with a thermal-optical instrument (Sunset lab

    This study presents a comparative, field-based hydrogeological characterization of exhumed, inactive fault zones in low porosity Triassic dolostones and limestones of the Hochschwab massif, a carbonate unit of high economic importance supplying 60% of the drinking water of Austria`s capital Vienna. The hydrogeology (groundwater storage and flow) of the massif has been reported to be essentially governed by karstified, large-scale faults. Previous work has shown that faults that formed during the Oligocene to Miocene lateral extrusion of the Eastern Alps act as groundwater pathways draining the karst massif preferably in E-W-direction. We present hydrogeological relevant data from these types of fault zones and a conceptual model, which supports the idea that fault-zone networks also have the potential to contribute significantly to the storage capacity of the aquifer. With respect to fault zone architecture and rock content, four types of faults are presented: (1) faults with single stranded, minor fault cores, (2) faults with single stranded, permeable fault cores, (3) faults with single stranded, impermeable fault cores, and (4) faults with multiple stranded, permeable fault cores. Within these faults cataclastic rocks and strongly cemented cataclastic breccias form low-permeability (< 1 mD) domains. Fractured rocks with fracture densities varying by a factor of 10 show significantly elevated porosities (> 3%) with respect to the country rock (< 1%). Dilation breccias with average porosities > 3% and permeabilities > 1000 mD form high-permeability domains. Our data illustrates significant differences in the architectural build-up of fault zones in dolostone (multiple-stranded cataclastic fault cores of weak lateral continuity, high volumes of intensely fractured rock) and limestone (laterally distinct, single-stranded fault cores, Riedel-shear fractures dominating fracture patterns). Karstic carbonate dissolution occurs preferentially along faults cores in

    In mountainous regions of Austria and of many other European countries, climate change may cause a further intensification of grassland management. Therefore, the effects of intensive cattle grazing on selected soil chemical and physical properties, above- and below-ground phytomass, forage quality, plant species composition and plant species richness at the scale of a representative paddock in a mountainous region of Austria were investigated. At the study site (Styrian Enns valley; 675 m a.s.l.), climate is relatively cool and humid, with a mean annual air temperature of 6.7°C and a mean annual precipitation of 970 mm, of which 66% falls during the vegetation period (April-October). The soil is a deep, base-rich Cambisol with a loamy sand texture. The paddock investigated has a total area of about 2 ha and had been grazed by dairy cows (Brown Swiss) five times per grazing season. The stocking density was 4 cows ha-1 during 180 days from early May to the end of October with a grazing time of about 8 hours per day. The strip grazed permanent pasture was manured annually for a long time, mostly with cattle slurry. Vegetation surveys were carried out using the method of Braun-Blanquet. Above- and below-ground phytomass, forage quality and mineral element concentration in the harvestable above-ground plant biomass were determined by using standard methods. During the grazing season surface soil samples (0-10 cm depth) for chemical analyses were collected before each grazing period (5 analyses of composite samples per site). At the beginning and the end of the grazing season also soil samples for physical analyses were taken from the topsoil (0-15 cm depth). Heavy cattle treading led to a substantial soil compaction especially in the 5-10 cm layer and to a deterioration of topsoil structure. The porous crumb structure was replaced by a compact platy structure. The topsoil was enriched with nutrients (mainly nitrogen, potassium, phosphorus and boron). The degree of

    In the course of highway constructions (Wiener Außenring-Schnellstraße (S1)) a detailed sedimentological transect of 1.8 km length was logged in deposits of the Central Paratethys near the village of Stetten, N of Korneuburg in Lower Austria. A total of 324 sediment- and 118 molluscan samples was studied. The siliciclastic succession consists of pelitic and sandy sediments and sandstones and is rich in fossils. The fossil remains consist of sponges, corals, serpulids, molluscs, balanids, echinoderms, fish and micromammals. Quantitatively the molluscs dominate and have been studied in detail. 139 species were determined from more than 11,000 shells. Two gastropod species, Agapilia pachii und Granulolabium bicinctum make up more than 53% of the assemblage. Another 11 species (Nassarius edlaueri, Bittium spina, Loripes dujardini, Hydrobia spp., Paphia subcarinata, Cyllenina ternodosa, Turritella gradata, Corbula gibba, Cerastoderma praeplicata, Striarca lactea, Sandbergeria perpusilla) each contributes more than 1% to the total molluscan composition, but all other 126 species are quantitatively unimportant. A conspicuous alternation between intertidal and shallow subtidal mollusc associations is evident. The intertidal is dominated by the superabundant Agapilia pachii and Granulolabium plicatum, whereas the heavily bioturbated fully marine subtidal is characterized by a more diverse assemblage including Turritella gradata, Nassarius edlaueri, Anadara diluvii and various venerids. Additionally, layers with large fragments of Crassostrea and thin coal deposits with Terebralia bidentata are quite abundant in the section. Washed in land snails (e.g., Planorbidae) and river snails (Melanopsidae) occur occasionally. This faunal composition, along with its typical alternation points to a vivid dynamic within this Lower Miocene, subtropical ecosystem in the paleo-estuary of the southern Korneuburg basin.

    An approach to establish the recharge component of managed aquifer recharge (MAR) has recently been proposed that uses small-diameter shallow wells installed using relatively inexpensive drilling methods such as direct push. As part of further development of that approach, a generalized procedure is presented for a technical and economic assessment of the approach's potential in comparison to other systems. Following this procedure, the use of small-diameter wells was evaluated both experimentally and numerically for a site located in southern Styria, Austria. MAR is currently done at the site using a horizontal pipe infiltration system, and system expansion has been proposed with a target rate of 12 l/s using small-diameter wells as one possible option. A short-duration single-well field recharge experiment (recharge rate 1.3-3.5 l/s) was performed (recharge by gravity only). Numerical modeling of the injection test was used to estimate hydraulic conductivity (K). Quasi-steady-state, single-well recharge simulations for different locations, as well as a long-term transient simulation, were performed using the K value calibrated from the field injection test. Results indicate that a recharge capacity of 4.1 l/s was achievable with a maximum head rise of 0.2 m at the injection well. Finally, simulations were performed for three different well fields (4, 6 and 8 wells, respectively) designed to infiltrate a target rate of 12 l/s. The experimental and numerical assessments, supported by a cost analysis of the small-diameter wells, indicate that the small-diameter wells are a viable, cost-effective recharge approach at this and other similar sites.

    Dykes in the Strudengau area (SW Moldanubian Zone, Austria) can be mineralogically divided into lamprophyres (spessartites and kersantites) and felsic dykes (granite porphyries, granitic dykes and pegmatoid dykes). Geochemical analyses of 11 lamprophyres and 7 felsic dykes show evidence of fractional crystallization. The lamprophyres are characterized by metaluminous compositions, intermediate SiO2 contents and high amounts of MgO and K2O; these rocks have high Ba (800-3000 ppm) and Sr (250-1000 ppm) contents as well as an enrichment of large-ion lithophile elements over high field strength elements, typical for enriched mantle sources with variable modifications due to fractionation and crustal contamination. This geochemical signature has been reported from durbachites (biotite- and K feldspar-rich mela-syenites particularly characteristic of the Variscan orogen in Central Europe). For most major elements, calculated fractionation trends from crystallization experiments of durbachites give an excellent match with the data from the Strudengau dykes. This suggests that the lamprophyres and felsic dykes were both products of fractional crystallization and subsequent magma mixing of durbachitic and leucogranitic melts. Rb-Sr geochronological data on biotite from five undeformed kersantites and a locally deformed granite porphyry gave cooling ages of c. 334-318 Ma, indicating synchronous intrusion of the dykes with the nearby outcropping Weinsberger granite (part of the South Bohemian Batholith, c. 330-310 Ma). Oriented matrix biotite separated from the locally deformed granite porphyry gave an Rb-Sr age of c. 318 Ma, interpreted as a deformation age during extensional tectonics. We propose a large-scale extensional regime at c. 320 Ma in the Strudengau area, accompanied by plutonism of fractionated magmas of syncollisional mantle-derived sources, mixed with crustal components. This geodynamic setting is comparable to other areas in the Variscan belt documenting an
