  2. Church Orientations in Central and Eastern Europe

    NASA Astrophysics Data System (ADS)

    Laužikas, Rimvydas

    The objective of this case study is to discuss church orientation in Central and Eastern Europe. Due to its geographical situation, this region is a specific part of European cultural space: it is remote from the main cultural centers, it was the last to adopt Christianity, and it experienced intensive interactions with Byzantine culture. Therefore, we can assess church orientation in Central and Eastern Europe as a tradition affected by multicultural interactions and in which there is an interlacement of Catholicism from Western Europe, Byzantinism, local pagan faiths and, in part, the ideas of conception of geographical space of the Jews, Karaites, and Muslims.

  3. Conductivity Anomalies in Central Europe

    2016-01-01

    This paper is a review of studies which, by applying the magnetotelluric, geomagnetic deep sounding, and magnetovariational sounding methods (the latter refers to usage of the horizontal magnetic tensor), investigate Central Europe for zones of enhanced electrical conductivity. The study areas comprise the region of the Trans-European Suture Zone (i.e. the south Baltic region and Poland), the North German Basin, the German and Czech Variscides, the Pannonian Basin (Hungary), and the Polish, Slovakian, Ukrainian, and Romanian Carpathians. This part of the world is well investigated in terms of data coverage and of the density of published studies, whereas the certainty that the results lead to comprehensive interpretations varies within the reviewed literature. A comparison of spatially coincident or adjacent studies reveals the important role that the data coverage of a distinct conductivity anomaly plays for the consistency of results. The encountered conductivity anomalies are understood as linked to basin sediments, asthenospheric upwelling, large differences in lithospheric age, and—this concerns most of them, which all concentrate in the middle crust—tectonic boundaries that developed during all mountain building phases that have taken place on the continent.

  4. Analysis of long-range transport of particulate matters in connection with air circulation over Central and Eastern part of Europe

    NASA Astrophysics Data System (ADS)

    Stefan, Sabina; Necula, Cristian; Georgescu, Florinela

    The aim of this paper is to establish a practical methodology for examining the long-range transport of particulate matters (PM), named TSP. The daily concentration values of TSP from years 2001 and 2002, for three sites, Baia Mare (RO), Vienna (AU), Aosta (IT), were analyzed. In order to connect the main air circulation types with the aerosol concentrations at the selected sites, the catalogues of Circulation and Weather type Classification (COST733) were used. Spectral analysis was made using spectrum software based on Lomb-Scargle periodograms, and multiresolution analysis (MRA) technique based on Maximal Overlap Discrete Wavelet Transform (MODWT) with Fejer-Korovkin in 22 points wavelet filter (waveslim package). Spectral analysis shows a dominant one-year periodicity for all the time series with a variance around 22% for each time series. In addition, several winters TSP pollution episodes from each city were analyzed using a back trajectory model (HYSPLIT4), in order to compare with the resulted air circulation types. Two important concluding remarks emerge: (i) the Eastern part of Europe shows a dominant easterly air circulation and central Europe is characterized by south-west air circulations, which drive the maxima of pollutant concentrations; (ii) the choice of the domain for analysis of the circulation types is very important.

    On November 1-5, 1994, the Energy & Environmental Research Center (EERC) and Power Research Institute of Prague cosponsored their second conference since 1991 in the Czech Republic, entitled ``Energy and Environment: Transitions in East Central Europe.`` This conference was a continuation of the EERC`s joint commitment, initiated in 1190, to facilitate solutions to short- and long-term energy and environmental problems in East Central Europe. Production of energy from coal in an environmentally acceptable manner is a critical issue facing East Central Europe, because the region continues to rely on coal as its primary energy source. The goal of the conference was to develop partnerships between industry, government, and the research community in East Central Europe and the United States to solve energy and environmental issues in a manner that fosters economic development. Among the topics addressed at the conference were: conventional and advanced energy generation systems; economic operation of energy systems; air pollution controls; power system retrofitting and repowering, financing options; regulatory issues; energy resource options; waste utilization and disposal; and long-range environmental issues. Selected papers in the proceedings have been processed separately for inclusion in the Energy Science and Technology database.

    2016-01-01

    The number of new cases of HIV infection has been decreasing in some parts of the world (e.g. sub-Saharan Africa) with the highest burden of disease in recent years. However, other regions are showing a different trend, such as Eastern Europe, the Middle East, North Africa and Central Asia. This trend seems also to apply to the Central European region. This article analyses HIV data for Central Europe derived from annual surveillance reports of the European Centre for Disease Prevention and Control (ECDC) and gives an overview of the recent status of the epidemic in this specific region. We show that, although still at a low level, the HIV epidemic in Central Europe continues to grow and requires more resources and interventions to curtail the ongoing epidemic. PMID:27482455

    Each year, rotavirus (RV) infection is the leading cause of acute gastroenteritis requiring hospitalisation and of nosocomially transmitted diseases in children younger than 5 years across Central European Vaccination Awareness Group (CEVAG) countries; however, inadequate surveillance systems and lack of routine RV testing still exist in most CEVAG countries, making it difficult to accurately assess the present burden of acute RV gastroenteritis in the younger population. Furthermore, routine immunisation of infants with RV vaccines has not been implemented, and no official and uniform recommendations exist in most of the countries in these territories. The present study provides CEVAG country-specific estimates of the disease burden of RV gastroenteritis among the youngest population and presents evidence-based advice on the use of RV vaccines in the region, while providing a framework for vaccination at the national level.

    1998-01-01

    For the last 50 years, the economic and industrial development of the nations of Central and Eastern Europe has been achieved at the cost of environmental degradation. The health risks posed by this pollution to children and the steps necessary to ameliorate such risks are only beginning to be investigated. At a recent conference in Poland, sponsored in part by the National Institute of Environmental Health Sciences, participants from 11 countries in the region, together with scientists from Western Europe and the United States, met to share information regarding pediatric environmental health in Central and Eastern Europe, to consider methodologic issues in the design and conduct of such studies, and to discuss preventive strategies. This report summarizes the deliberations, outlines problem areas such as heavy metals and air pollution, delineates research and training needs to help Central and Eastern Europeans deal more effectively with such problems, and recommends specific future actions and collaborative efforts.

  10. Cenozoic continental climatic evolution of Central Europe.

    2005-10-18

    Continental climate evolution of Central Europe has been reconstructed quantitatively for the last 45 million years providing inferred data on mean annual temperature and precipitation, and winter and summer temperatures. Although some regional effects occur, the European Cenozoic continental climate record correlates well with the global oxygen isotope record from marine environments. During the last 45 million years, continental cooling is especially pronounced for inferred winter temperatures but hardly observable from summer temperatures. Correspondingly, Cenozoic cooling in Central Europe is directly associated with an increase of seasonality. In contrast, inferred Cenozoic mean annual precipitation remained relatively stable, indicating the importance of latent heat transport throughout the Cenozoic. Moreover, our data support the concept that changes in atmospheric CO2 concentrations, although linked to climate changes, were not the major driving force of Cenozoic cooling.

  11. Why (not) go east? Comparison of findings from FDA Investigational New Drug study site inspections performed in Central and Eastern Europe with results from the USA, Western Europe, and other parts of the world.

    Since the mid-1990s, investigational sites in the countries of Central and Eastern Europe (CEE) have been increasingly utilized by pharmaceutical companies because of their high productivity in terms of patient enrolment into clinical trials. Based on the FDA's publicly accessible Clinical Investigator Inspection List, we present an analysis of findings and outcome classifications from FDA inspections during Investigational New Drug (IND) studies and compare the results for the CEE region to those from Western European countries and the USA. Data from all 5531 FDA clinical trials inspections that occurred between 1994 (when the FDA first performed inspections in CEE) and the end of 2010 were entered into the database for comparative analysis. Of these, 4865 routine data audit (DA) inspections were analyzed: 401 from clinical trials performed in Western Europe, 230 in CEE, 3858 in the USA, and 376 in other countries. The average number of deficiencies per inspection ranged between 0.99 for CEE and 1.97 in Western Europe. No deficiencies were noted during 16.6%, 39.0%, and 21.5% of the inspections in Western Europe, CEE and USA, respectively. The percentages of inspections after which no follow-up action was indicated were 36.9% for Western Europe, 55.7% for CEE, and 44.3% for US sites. CEE was also the region with the lowest percentage of inspections that required official or voluntary action. On the basis of FDA inspection data, the high productivity of CEE sites appears to be accompanied by regulatory compliance as well as by data quality standards that are not inferior to those in Western regions.

    Problems in midwifery in many Central-Eastern European countries are very similar; it is possible to speak about the evolving Central-Eastern model of midwifery care. The educational models of this region have a relatively strong theoretical part; however, there is an insufficient practical dimension. Theoretical part of midwifery education in the universities is relatively autonomous and is slowly changing the professional identity of graduates. PMID:26632483

    The Iberian Massif is the best exposed segment of the European Variscan Belt. It includes relatively well preserved terranes that were accreted by transpression along time and resulted in a number of geotectonic units that formed part of the Late Paleozoic assembly of the Pangaea Supercontinent. In SW Iberia, these units are the Central Iberian Zone (CIZ), Ossa Morena Zone (OMZ), and the South Portuguese Zone (SPZ). A 210 km long NE-SW magnetotelluric profile was carried out through the CIZ, from the OMZ-CIZ boundary toward the north, reaching the Tagus (Cenozoic) basin. Data dimensionality analysis resulted in a suitable 2-D electrical resistivity structure, allowing a 2-D inversion of the data set. Complementary available geophysical data (deep seismic, gravity and aeromagnetic) and a comparison with a detailed geological cross section led us to constrain the interpretation of the 2-D electrical resistivity structure of the CIZ crust. The results show, for the upper crust, the existence of diverse conductive/resistive bodies that correlate well with known geological features (sedimentary basins, faults, granitic plutons, mineralized systems). A mild but steady conductive band is located along the middle and lower crust that is interpreted as a mafic granulite basement. The upper section of this band connects with several elongated shallow conductors, providing further evidence for the existence, in the Central Iberian Zone, of a complex décollement system where the major faults are rooted. Such a crustal architecture is viewed as the northward continuation of the Variscan large-scale structures previously recognized in the southern sectors (OMZ and SPZ).

  15. Environmental applications of ion chromatography in Eastern and Central Europe.

    2010-08-01

    Environmental analytics is one of the most important applications of ion chromatography. It includes determination of ions in water and wastewater as well as in gaseous and solid ones. Nowadays, ion chromatography has almost completely displaced the classical methods of ion determination in these areas. In spite of the fact that the ion chromatography has been officially present in the scientific world for 36 years, its role and popularity is highly diversified in various countries and regions of the world. In highly industrialized countries, it has been a reference method of water and wastewater analysis for years. In other parts of the world, it is not used and appreciated sufficiently despite its undeniable advantages. The following paper is a short overview of the most highly cited scientific and research institutions that conduct research in terms of environmental applications of ion chromatography in Eastern and Central Europe. Furthermore, the paper presents a list of a number of scientific papers referring to the discussed area, published in the years 1996-2009 in some of the most highly cited international scientific journals, and concerning publications of scientists from Eastern and Central Europe seen against the background of Europe and the world.

  16. Monthly shortage trends for Central and Western Europe

    2009-09-01

    Monthly shortage time trends are analysed for Central and Western Europe by considering more than 100 rain records (European Climate Assessment, ECA, and the Spanish Agencia Estatal de Meteorología, AEMET) covering the whole 20th century. Spells of monthly shortage are defined as consecutive months with amounts lowering the corresponding monthly median. Three annual variables are analysed: the average,, the largest, SM, and the cumulative, CS, monthly shortage. Due to the quite irregular annual evolution of these three variables, the Kendall-tau algorithm instead of a simple linear regression of the series has been applied to evaluate time trends. Positive and negative trends, never exceeding ±4.0 mm/decade, have been obtained for the three variables within the area delimited by 10°W-25°E longitude and 35°N-65°N latitude. The statistical significance at 95% level of local time trends has been assessed with the Mann-Kendall test. Additionally, the field significance of time trends is assessed by Monte Carlo simulations, randomly reproducing magnitudes and signs of time trends. The low number of empirical significant trends induces lack of field significance. A relatively high number of significant local trends (25) is only detected for CS, 6 of them are positive and 19 negative. Given that local significant trends are scattered throughout Central and Western Europe, a single spatial pattern for the monthly shortage should be discarded. Nevertheless, a close revision of local trends (statistically significant or not) manifests that positive values (increasing monthly shortage) are observed in France, a great part of the Iberian Peninsula, Central Europe and Italy.

    ABSTRACT Pneumococcal infection is a major cause of morbidity and mortality worldwide. The burden of disease associated with S. pneumoniae is largely preventable through routine vaccination. Pneumococcal conjugate vaccines (e.g. PCV7, PCV13) provide protection from invasive pneumococcal disease as well as non-invasive infection (pneumonia, acute otitis media), and decrease vaccine-type nasopharyngeal colonisation, thus reducing transmission to unvaccinated individuals. PCVs have also been shown to reduce the incidence of antibiotic-resistant pneumococcal disease. Surveillance for pneumococcal disease is important to understand local epidemiology, serotype distribution and antibiotic resistance rates. Surveillance systems also help to inform policy development, including vaccine recommendations, and monitor the impact of pneumococcal vaccination. National pneumococcal surveillance systems exist in a number of countries in Central and Eastern Europe (such as Croatia, Czech Republic, Hungary, Poland, Romania and Slovakia), and some have introduced PCVs (Czech Republic, Hungary, Kazakhstan, Russia, Slovakia and Turkey). Those countries without established programs (such as Kazakhstan, Russia and Ukraine) may be able to learn from the experiences of those with national surveillance systems. The serotype distributions and impact of PCV13 on pediatric pneumococcal diseases are relatively similar in different parts of the world, suggesting that approaches to vaccination used elsewhere are also likely to be effective in Central and Eastern Europe. This article briefly reviews the epidemiology of pneumococcal disease, presents the latest surveillance data from Central and Eastern Europe, and discusses any similarities and differences in these data as well the potential implications for vaccination policies in the region.

    The countries of Eastern and Central Europe have emerged from a political system which for decades has ignored protection of human health from hazardous wastes. While the economies of the countries in this region are stretched, awareness and concern about hazardous waste issues are a part of the new realities. At a recent conference sponsored in part by the National Institute of Environmental Health Sciences, representatives of seven countries in the region described the status of hazardous waste programs, issues of major concern, and steps being taken to protect human health. This report summarizes the deliberations, outlines some of the problems remaining in dealing with the legacy of the past, addressing the problems of the present, and providing a framework for future research and collaborative efforts.

  20. Modeling neolithic dispersal in central Europe: demographic implications.

    PubMed

    Galeta, Patrik; Sládek, Vladimír; Sosna, Daniel; Bruzek, Jaroslav

    2011-09-01

    On the basis of new examination of ancient DNA and craniometric analyses, Neolithic dispersal in Central Europe has been recently explained as reflecting colonization or at least a major influx of near eastern farmers. Given the fact that Neolithic dispersal in Central Europe was very rapid and extended into a large area, colonization would have to be associated with high population growth and fertility rates of an expanding Neolithic population. We built three demographic models to test whether the growth and fertility rates of Neolithic farmers were high enough to allow them to colonize Central Europe without admixture with foragers. The principle of the models is based on stochastic population projections. Our results demonstrate that colonization is an unlikely explanation for the Neolithic dispersal in Central Europe, as the majority of fertility and growth rate estimates obtained in all three models are higher than levels expected in the early Neolithic population. On the basis of our models, we derived that colonization would be possible only if (1) more than 37% of women survived to mean age at childbearing, (2) Neolithic expansion in Central Europe lasted more than 150 years, and (3) the population of farmers grew in the entire settled area. These settings, however, represent very favorable demographic conditions that seem unlikely given current archaeological and demographic evidence. Therefore, our results support the view that Neolithic dispersal in Central Europe involved admixture of expanding farmers with local foragers. We estimate that the admixture contribution from foragers may have been between 55% and 72%.

    The presented plate tectonic model focuses on Silurian to Early Carboniferous evolution of Central Europe with special attention given to the Sudetes region (north and north-east part of the Bohemian Massif). During our studies, we tested alternative models focused on the position of the Armorican terranes, known as the Armorican Terrane Assembly (ATA) (e.g.: Matte, 2001) and tried to refine the existing reconstructions, which describe Armorica as an individual continent during the Late Silurian and Devonian (e.g. Lewandowski, 2003, Winchester, 2002). Our plate tectonic model depict that these small blocks were scattered along the northern margin of Gondwana, where they formed the "Armorican Spour" as suggested by Kroner and Romer (2013). The seaways were present between blocks. Because of the north dipping subduction zone along the southern margin of the Laurussia continent the back-arc basin and island arc were formed. The narrowing of the Rheic ocean led to the complicated collision of Gondwana and Laurussia. Three main stages of this event can be distinguished: (1) collision of the Armorican Spour with the Laurussian island arc, (2) back-arc basin closure, (3) final Gondwana and Laurussian collision. Those stages correlate well with Variscan Subduction Zone System proposed by Kroner and Romer (2013). Interactive modeling performed in GPlates, shows that the presented model is valid from kinematic and geometrical point of view.

    Central Europe is largely safe from accidents with venomous and poisonous animals. The regions where European vipers are regularly found are shrinking. Today accidents with jellyfish and stings of venomous fish afflicted during leisure activities at the sea side play the dominant role. Life threatening accidents in Europe are mainly due to exotic snakes held in captivity. A system useful in daily medical practice is explained to classify and stage accidents due to poisonous and venomous animals. The important poisonous and venomous animals of Central Europe and the specific therapeutics, the antivenoms, are covered. The antivenom depot "Antivenin-CH" of the Swiss Toxicology Information Centre in Zurich and the MRITox in Munich with the antivenom registry Munich AntiVenom INdex (MAVIN) are presented.

    The horizontal strain field of the Bohemian Massif, central Europe, was assessed from GNSS data monitored on permanent stations of the Geodynamic Network of the Academy of Science of the Czech Republic (GEONAS) and of the Czech Office for Surveying, Mapping and Cadastre (CZEPOS). For every area a representative motion velocity was determined. Their comparison with general motions of the Eurasian plate ascertained by the NNR-NUVEL-1A model gave deviations characterizing recent influence of the Alps to the northern geological units, in our case the Bohemian Massif. From these motions a regional pattern of the horizontal strain field for the Bohemian Massif had been calculated. It was found that (i) the northern part of the Massif is under dominant E-W extensions and (ii) slight contractions were detected for the NNE-SSW direction in eastern regions of the Massif. Obtained results will be presented and discussed from a viewpoint of the Alpine structural unit actions to surrounding geological units.

    Central Europe has experienced environmental degradation for hundreds of years. The proximity of countries, their shared resources, and transboundary movement of environmental pollution, create the potential for regional environmental strife. The goal of this project was to identify the sources and sinks of environmental pollution in Central Europe and evaluate the possible impact of transboundary movement of pollution on the countries of Central Europe. In meeting the objectives of identifying sources of contaminants, determining transboundary movement of contaminants, and assessing socio-economic implications, large quantities of disparate data were examined. To facilitate use of the data, the authors refined mapping procedures that enable processing information from virtually any map or spreadsheet data that can be geo-referenced. Because the procedure is freed from a priori constraints of scale that confound most Geographical Information Systems, they have the capacity to generate new projections and apply sophisticated statistical analyses to the data. The analysis indicates substantial environmental problems. While transboundary pollution issues may spawn conflict among the Central European countries and their neighbors, it appears that common environmental problems facing the entire region have had the effect of bringing the countries together, even though opportunities for deteriorating relationships may still arise.

    In Germany, Eryngium campestre is restricted to dry habitats along the rivers Rhine and Elbe and to a few areas in Central Germany. This distribution pattern is usually regarded as a typical pattern of postglacial immigration. In the present study, we investigated whether these two geographically distinct distribution areas are genetically differentiated and whether conclusions can be drawn regarding colonization history. To analyse the phylogeographic structure of E. campestre in Central Europe, 278 individuals from 29 populations within Germany and from further reference populations within Europe were analysed. We applied amplified fragment length polymorphisms to examine their genetic relatedness. Our analyses revealed three groups: a Mediterranean group additionally including two Rhine populations; a Rhine-Main group which further includes the westernmost population from the central German dry area; and one group which includes all eastern populations. Our results show that the two geographically distinct areas are genetically differentiated. As genetic diversity within the Elbe populations is very low, we conclude that this area, which was strongly affected through the late glacial maximum, was colonized relatively recently. High genetic diversity in the Rhine populations indicates a contact zone where lineages of different origin met. This would imply that today's patterns of genetic variation were caused through glacial range contractions and expansions. The present study is one of the first studies that deal with the postglacial distribution pattern of a dry grassland plant species in Central Europe and the results suggest that a survival of E. campestre at least during the Dryas cold stage might be possible.

    Northern Central Europe is regarded as aseismic, however, several historic earthquakes with intensities of up to VII occurred in this region during the last 1000 years. This historic seismicity is clearly concentrated along major reverse faults that formerly played an important role during a tectonic inversion phase in the Late Cretaceous. Here we show with numerical simulations that large parts of the observed seismicity in northern Central Europe is most likely an effect of stress changes induced by the decay of the Scandinavian ice sheet after the Weichselian glaciation and the interference with the background stress field related to the ongoing convergence of Africa and Europe. Many of the historic earthquakes concentrate for a certain time along one fault and there is even evidence for distinct earthquake clusters in northern Central Europe e.g. along the Osning Thrust or at least along closely spaced faults like in the Gardelegen area. Such a distribution fits the characteristics of other intraplate seismic zones like the eastern United States and requires a re-evaluation of the seismic hazard potential of northern Central Europe, especially in view of the revived search for nuclear waste repositories and ongoing discussions about CO2 sequestration projects in the area.

  17. Estimation of the average visibility in central Europe

    NASA Astrophysics Data System (ADS)

    Horvath, Helmuth

    Visibility has been obtained from spectral extinction coefficients measured with the University of Vienna Telephotometer or size distributions determined with an Aerosol Spectrometer. By measuring the extinction coefficient in different directions, possible influences of local sources could be determined easily. A region, undisturbed by local sources usually had a variation of extinction coefficient of less than 10% in different directions. Generally good visibility outside population centers in Europe is considered as 40-50 km. These values have been found independent of the location in central Europe, thus this represents the average European "clean" air. Under rare occasions (normally rapid change of air mass) the visibility can be 100-150 km. In towns, the visibility is a factor of approximately 2 lower. In comparison to this the visibility in remote regions of North and South America is larger by a factor of 2-4. Obviously the lower visibility in Europe is caused by its higher population density. Since the majority of visibility reducing particulate emissions come from small sources such as cars or heating, the emissions per unit area can be considered proportional to the population density. Using a simple box model and the visibility measured in central Europe and in Vienna, the difference in visibility inside and outside the town can be explained quantitatively. It thus is confirmed, that the generally low visibility in central Europe is a consequence of the emissions in connection with human activities and the low visibility (compared, e.g. to North or South America) in remote location such as the Alps is caused by the average European pollution.

    Parasitic helminths and helminthoses do not only occur in the tropics and subtropics but are also prevalent in Austria and other Central European countries. Their prevalence is, however, more or less rather low. In total, we know more than 20 helminth species, which are diagnosed regularly in Austria; some of them occur in Austria autochthonously, some others are acquired abroad and are transferred as souvenirs to Central Europe. The spectrum of helminths described in this overview comprises species of the trematodes (flukes), cestodes (tapeworms), and nematodes (roundworms).The topic "Helminths and helminthoses in Central Europe" is divided into three parts: The first part comprises a short introduction into the field of medical helminthology and is primarily dedicated to the description of trematodes and trematode-caused diseases.

    Since the Mesozoic, central Europe tectonics has been dominated by the closure of the Tethyan Ocean as the African and European plates collided. This was accompanied by subduction, orogeny (the Alpine - Carpathian mountain chain), and microplate accretion. In the Mid-Miocene lithospheric extension formed the Pannonian Basin; this extension has been variously ascribed to slab roll-back, lithospheric gravitational instability or mantle extrusion. We present SKS splitting measurements for central Europe from temporary seismological deployments of the Carpathian Basins Project (CBP, 2005-2007) and the South Carpathian Project (SCP, 2009-2011), together with stations from permanent national networks. This provides a station spacing on the order of 50 - 70 km from the Eastern Alps across the Pannonian Basin and Carpathians to the East European platform with which to test geodynamic models for the region. SKS splitting delay times are between 0.7 - 1.5 s with a regional NW-SE trend of fast directions across the eastern Pannonian-Carpathian region, turning to parallel the tectonic strike in the Alps but perturbed by extension in the western Pannonian, the presence of the East European platform and the lithospheric instability in the Vrancea region of Romania. The fast polarisation orientations are correlated with upper mantle and transition zone tomographic images from a recent finite frequency study with the aim of controlling variations in mantle heterogeneity. The consistency of the regional anisotropy trends across much of central Europe imply olivine orientation perpendicular to the principal compressive stresses created by the collision of Adria and Europe, perturbed by Miocene extension of the Pannonian Basin and present-day lithospheric instability of the Vrancea region.

    Extreme seasonal fluctuations of the surface-air temperature characterize the climate of central Europe, 45-60 deg North Temperature difference between warm 1990 and cold 1996 in the January-March period, persisting for more than two weeks at a time, amounted to 18 C for extensive areas. These anomalies in the surface-air temperature stem in the first place from differences in the low level flow from the eastern North-Atlantic: the value of the Index 1na of southwesterlies over the eastern North-Atlantic was 8.0 m/s in February 1990, but only 2.6 m/ s in February 1996. The primary forcing by warm advection to positive anomalies in monthly mean surface temperature produced strong synoptic-scale uplift at the 700 mb level over some regions in Europe. The strong uplift contributed in 1990 to a much larger cloud-cover over central Europe, which reduced heat-loss to space (greenhouse effect). Thus, spring arrived earlier than usual in 1990, but later than usual in 1996.

    On March 28-29, 2000, epidemiologists and microbiologists convened in Warsaw, Poland, to discuss emerging, re-emerging, and drug-resistant infections in central and eastern Europe. Delegates were from the Czech Republic, Greece, Hungary, Latvia, Poland, Romania, Russia, and Yugoslavia, with the exception of the US and the UK and other worst affected countries in central-eastern Europe. It has been documented that the cause of diphtheria epidemics in several countries in the mid-1990s resulted from the breakdown of vaccination campaigns following social dislocation. Currently, diphtheria morbidity has declined through targeted vaccination programs, although fundamental socioeconomic problems continue to threaten public health. Other infectious diseases raised during the conference were the evolution of tuberculosis and HIV/AIDS, which remains largely unpredictable. In addition, the growing incidence of multidrug-resistant tuberculosis is documented in several countries. Among the major problems in tuberculosis control include late diagnosis, nonexistent or erratic drug supplies and unreliable reporting. The syringe ecosystem in both healthcare settings and injecting drug users were singled out as the vectors of sharp increase in HIV/AIDS infection. Throughout the conference, the recurrent theme was on the overriding importance of providing specialized training and the building up of networks of public health specialists.

    We propose an updated wind speed scale description adapted for Central Europe considering wind impact to buildings as well as to vegetation. The scale is motivated by the need of a broadly applicable, accurate and consistent tornado or downburst intensity rating system based on a standardised wind speed scale for the purpose of climatological homogeneity. The description comprises building and vegetation damage characteristics, which can be found in Central Europe - but similar in other parts of the world, occurring with the various classes of the Fujita- and T-scales. The scale description is supplemented by photographs of typical damage. For practical application, an ensemble-based use of a decision matrix for specific building structures and vegetation types is suggested.

Nowadays [in some countries, such as the Czech Republic,]...the decrease continues and in [other] countries (Lithuania, Latvia, Estonia) the infant mortality rate has temporarily increased due to adoption of the international definition of live and still births, while in [the] majority of countries of the previous Soviet Union and former Yugoslavia...infant mortality...has increased."

    Last year, about 75 project proposals were made to the Dutch Ministry of Housing, Physical Planning and the Environment, and the number likely will be greater this year. They were submitted mainly by Dutch industrial and consultancy firms, and covered a broad area of activity - policy planning, support for environmental groups, environmental monitoring networks, emissions abatement, water quality research, and the like. Various criteria are used to evaluate project proposals - typically the priority of the problem being addressed, and the environmental benefit expected to arise from the solution. Special attention is given to Dutch initiatives centering on large-scale problems, such as curbing nitrogen oxides and sulfur dioxide emissions from power plants. This paper reports how expanded Dutch policy will bring economic, advisory aid aimed at abating pollution, managing environment to nations of central eastern Europe.

    This paper discusses financing options available for energy (power/steam) projects in East Central Europe. It is intended to be an overview and practical guide to such options in today`s environment. A survey is made of the principal multilateral and other financial institutions providing funding and/or credit support in the region. These include the European Bank for Reconstruction and Development, the World Bank, the International Finance Corporation, the export credit agencies, and the commercial banks. Specific guarantee and other support mechanisms which some of these institutions provide are covered, including the latest developments. In addition to loan financing, potential sources of equity financing are discussed. Next, a description of the credit rating process by such institutions as Standard and Poor`s, and an example of a successful rating effort in the Czech Republic, lead into a discussion of accessing foreign and domestic bond markets to finance energy projects in the region.

    The statistical evaluation of the relationships between atmospheric circulation types and areal precipitation events took place in the context of an international project called WETRAX (Weather patterns, storm tracks and related precipitation extremes). The aim of the project was to estimate the regional flooding potential in Central Europe under enhanced climate change conditions. For parts of southern Central Europe, a gridded daily precipitation set with 6km horizontal resolution has been generated for the period 1951-2006 by the Austrian Zentralanstalt für Meteorologie und Geodynamik (ZAMG). To determine regions with similar precipitation variability, a S-mode principal component analysis has been applied. Extreme precipitation events are defined by the 95% percentile, based on regional arithmetic means of daily precipitation. Large-scale atmospheric circulation types have been derived by different statistical methods and variables using the COST733 classification software and gridded daily NCEP1 reanalysis data. To evaluate the performance of a particular circulation type classification with respect to regional precipitation extremes, multiple regression models have been derived between the circulation type frequencies as predictor variables and monthly frequencies of extreme precipitation as well as monthly rainfall amounts from these events. To estimate the regional flooding potential in Central Europe under enhanced climate change conditions, multiple regression models are applied to different projected GCM predictor data. Thus, future changes in circulation type occurrence frequencies are transferred into assessments of future changes in precipitation extremes on a regional scale.

    In Europe, sandflies (Diptera: Psychodidae: Phlebotominae) are typical Mediterranean faunal elements of low expansivity, which are widely distributed in more than 20 species in many parts of Southern Europe. A few species have extended their distribution to the northwest invading extramediterranean regions (Western, Eastern Europe); any occurrence in Central Europe north of the Alps was excluded until recently. Since 1999 sandflies have been found in several parts in Germany and in Belgium; originally these records were ascribed to climate change and global warming. Meanwhile, the more likely assumption is that sandflies have always, probably since the Holocene climate optima (ca. 4500 and 2500 B.C.), been in Central Europe sporadically to where they have come as immigrants (or re-immigrants) from Mediterranean refugial areas. It is, however, without question that global warming will lead to an extension of the distributional areas of sandflies. A climatological analysis of the localities where sandflies have been found in Central Europe has revealed that temperature is the key factor. A comparison of climatological parameters in sandfly-localities with the climatic conditions in Austria (where sandflies have not yet been found) has shown that an increase of temperature by 1 degrees C in January (Ph. mascittii) or 1 degrees C in July (Ph. neglectus), respectively, would lead to suitable conditions for the occurrence of sandflies in certain parts of Austria. (The scenarios for an increase of temperature until the end of the century vary between 1.5 degrees C to 4.5 degrees C; 3 degrees C seem to be realistic also for critical climatologists.) Leishmaniae certainly do not occur in Central Europe primarily, but an increasing number of infections in humans, as well as in animals, acquired in Central Europe has been registered. It is highly likely that these infections are due to sandflies which have been infected by sucking blood on infected dogs. Dogs infected with

    Harm reduction (HR) interventions began in Central-Eastern Europe and Central Asia in the mid-1980s with the establishment of substitution treatment (ST) in Yugoslavia. In the mid-1990s, the first needle and syringe programmes (NSPs) opened in selected countries following the outbreaks of HIV among injecting drug users (IDUs). The number of NSPs continues to increase via a combination of international and state funding with large expansions made possible via the Global Fund to Fight AIDS, Tuberculosis and Malaria. While ST is still unaccepted in several countries, others have made some progress which is especially visible in South Eastern and Central Europe and the Baltic States. Development of regional networking including Central and Eastern European HR Network and a number of national networks helped to coordinate joint advocacy effort and in some cases sustain HR services. Activism of drug users and people living with HIV (PLWH) increased in the region in the last several years and helped to better link HR with the affected communities. Still a number of challenges remain important for the movement today such as repressive drug policies; stigma and discrimination of IDUs, PLWH, sex workers and inmates, including poor access to prevention and treatment; lack of important components of HR work such as naloxone distribution and hepatitis B vaccination, prevention in prisons; issues of quality control; sustaining services after finishing of major international projects; reaching of adequate coverage and others.

    Introgressive hybridization is an important evolutionary process frequently contributing to diversification and speciation of angiosperms. Its extent in other groups of land plants has only rarely been studied, however. We therefore examined the levels of introgression in the genus Diphasiastrum, a taxonomically challenging group of Lycopodiophytes, using flow cytometry and numerical and geometric morphometric analyses. Patterns of morphological and cytological variation were evaluated in an extensive dataset of 561 individuals from 57 populations of six taxa from Central Europe, the region with the largest known taxonomic complexity. In addition, genome size values of 63 individuals from Northern Europe were acquired for comparative purposes. Within Central European populations, we detected a continuous pattern in both morphological variation and genome size (strongly correlated together) suggesting extensive levels of interspecific gene flow within this region, including several large hybrid swarm populations. The secondary character of habitats of Central European hybrid swarm populations suggests that man-made landscape changes might have enhanced unnatural contact of species, resulting in extensive hybridization within this area. On the contrary, a distinct pattern of genome size variation among individuals from other parts of Europe indicates that pure populations prevail outside Central Europe. All in all, introgressive hybridization among Diphasiastrum species in Central Europe represents a unique case of extensive interspecific gene flow among spore producing vascular plants that cause serious complications of taxa delimitation.

    Efficient monitoring of earthquakes and determination of their magnitudes are necessary for developing earthquake catalogues at a regional and national levels. Unification and homogenization of the catalogues in terms of magnitudes has great importance for seismic hazard assessment. Calibrated local earthquake magnitude scales are commonly used for determining magnitudes of regional earthquakes by all national seismological services in the Central Europe. However, at the local scale, each seismological service uses its own magnitude determination procedure. There is no systematic comparison of the approaches and there is no unified procedure. We present a comparison of the local magnitude scales used by the national seismological services of Slovakia (Geophysical Institute, Slovak Academy of Sciences), Czech Republic (Institute of Geophysics, Academy of Sciences of the Czech Republic), Austria (ZAMG), Hungary (Geodetic and Geophysical Institute, Hungarian Academy of Sciences) and Poland (Institute of Geophysics, Polish Academy of Sciences), and by the local network of seismic stations located around the Nuclear Power Plant Jaslovske Bohunice, Slovakia. The comparison is based on the national earthquake catalogues and annually published earthquake bulletins for the period from 1985 to 2011. A data set of earthquakes has been compiled based on identification of common events in the national earthquake catalogues and bulletins. For each pair of seismic networks, magnitude differences have been determined and investigated as a function of time. The mean and standard deviations of the magnitude differences as well as regression coefficients between local magnitudes from the national seismological networks have been computed. Results show relatively big scatter between different national local magnitudes and its considerable time variation. A conversion between different national local magnitudes in a scale 1:1 seems inappropriate, especially for the compilation of the

    The policy of the European co-operation in the new atmosphere of an international solidarity became one of the priorities of the European Federation of Neurological Societies (EFNS). It could be hardly pursued more efficiently in any other field of neurological performance as in education. To review several aspects of neurological practice and education the 'First European Co-operation Neurology Workshop' was held in the castle of Trest', Czech Republic, 13-20 April 2000. Participants from 15 countries (Albania, Belarus, Bulgaria, Croatia, Czech Republic, Estonia, Georgia, Hungary, Moldova, Poland, Romania, Russia, Slovak Republic and Slovenia), covering a region of 316 million inhabitants and 25 000 neurologists, presented their national postgraduate education systems (besides other topics). We refer data on density of medical doctors and that of neurologists, pre-board certification phase, board examination, continuing medical education (CME), and qualification rewards. Illustrative data were put in the comparative tables.

    In the early nineties the region of Central and Eastern Europe (CEE, more than 1 million km² and 100 million inhabitants) went through fundamental political, economic and social changes which eventually led to the European integration process. This positively influenced urban water and wastewater management , which had an unbalanced structure and rather low level of development. The paper outlines first the 1990 situation (water supply, sewerage and wastewater treatment (WWT)) and the infrastructure development of the last two decades, on the basis of a comprehensive data collection for six countries (Bulgaria, the Czech Republic, Hungary, Poland, Romania and Slovakia). Austria serves as a reference basis. Alterations of some of the drivers such as GDP (Gross Domestic Product), water tariff, investment funding and legislation are studied in detail. Then, the paper focuses on WWT by analyzing data of 20 large plants. Influent and effluent quality is evaluated. Technology indicators are estimated and assessed. They include plant removal rates and violation ratios assuming the application of the Urban Wastewater Directive, primary clarifier removal rates, actual anoxic volume and sludge age in comparison with the recommendations of the ATV guideline, criteria of secondary settling tanks and energy consumption. Finally, nutrient removal rates and upgrading options are outlined.

    Many studies indicate a gradual increase in danger of wildfire in Central Europe. The risk of wildfire differs greatly among individual areas (whether regions or districts), and this difference remains, irrespective of the methods used to describe the danger of wildfires. For this study was used the calculation of the FDI (Fire Danger Index) for 200 stations on the territory of Czech Republic in the period 1961-2008. The FDI model is being developed in the Doksany observatory based on evaluation of weather conditions. FDI model describes danger of wildfire for vegetation covered countryside. There are five levels of danger: 1 - very low risk, 2 - low risk, 3 - moderate risk, 4 - high risk, 5 - very high risk. During processing the model compute upper soil profile moisture, surface moistening and the speed of spread of wildfire. Between years 1991-2008 there was an increase in the average monthly FDI indices in comparison to the period 1961-1990. During this period, a statistically significant trend toward higher indices was found (0.02 FDI index/year). The trend of danger of wildfires growth was evident in all months.

    The occurrence and characteristics of mesocyclones in Central Europe as seen by radar are analysed. A three year analysis shows an annual and diurnal cycle with a wider maximum in the late afternoon/evening compared to the diurnal cycle of general thunderstorms. Analysis of F2 tornado events and over a hundred hail storms show the characteristics of the corresponding mesocyclones as seen by radar. For all of the six F2 tornadoes in the three-year period in Germany a corresponding mesocyclone could be detected in radar data. Furthermore the analysis reveals that about half of all hail storms in Germany are associated with a mesocyclone detected in radar data within 10 km and 10 min. Some mesocyclone attributes, e.g. depth and maximum shear, and of the associated convective cell, e.g. reflectivity related parameters VIL, VILD and echotop, have predictive skill for indicating the occurrence of hail. The mesocyclone detection algorithm may support the analysis and nowcasting of severe weather events and thus support the warning process.

    Like many elements, fluorine (which generally occurs in nature as fluoride) is beneficial to human health in trace amounts, but can be toxic in excess. The links between low intakes of fluoride and dental protection are well known; however, fluoride is a powerful calcium-seeking element and can interfere with the calcified structure of bones and teeth in the human body at higher concentrations causing dental or skeletal fluorosis. One of the main exposure routes is via drinking water and the World Health Organisation currently sets water quality guidelines for the element. In Central Europe, groundwater resources that exceed the guideline value of 1.5 mg l-1 are widespread and effects on health of high fluoride in water have been reported. The aim of the current project was to develop a geographic information system (GIS) to aid the identification of areas where high-fluoride waters and fluorosis may be a problem; hence, where water treatment technologies should be targeted. The development of the GIS was based upon the collation and digitisation of existing information relevant to fluoride risk in Ukraine, Moldova, Hungary and Slovakia assembled for the first time in a readily accessible form. In addition, geochemistry and health studies to examine in more detail the relationships between high-fluoride drinking waters and health effects in the population were carried out in Moldova and Ukraine demonstrating dental fluorosis prevalence rates of 60-90% in adolescents consuming water containing 2-7 mg l-1 fluoride.

    The comeback of the Eurasian beaver (Castor fiber) throughout western and central Europe is considered a major conservation success. Traditionally, several subspecies are recognised by morphology and mitochondrial haplotype, each linked to a relict population. During various reintroduction programs in the 20th century, beavers from multiple source localities were released and now form viable populations. These programs differed in their reintroduction strategies, i.e., using pure subspecies vs. mixed source populations. This inhomogeneity in management actions generated ongoing debates regarding the origin of present beaver populations and appropriate management plans for the future. By sequencing of the mitochondrial control region and microsatellite genotyping of 235 beaver individuals from five selected regions in Germany, Switzerland, Luxembourg, and Belgium we show that beavers from at least four source origins currently form admixed, genetically diverse populations that spread across the study region. While regional occurrences of invasive North American beavers (n = 20) were found, all but one C. fiber bore the mitochondrial haplotype of the autochthonous western Evolutionary Significant Unit (ESU). Considering this, as well as the viability of admixed populations and the fact that the fusion of different lineages is already progressing in all studied regions, we argue that admixture between different beaver source populations should be generally accepted.

    The overall situation as regards dietary intake and nutritional status in the countries of Central and Eastern Europe has varied considerably during previous decades; however, after the political, social and economic changes during the nineties these differences have increased further, especially in the areas with low GDP and war, and in the regions affected by radionuclides etc. No systematic surveillance systems in representative samples of adolescents were in effect at the beginning of the nineties in Central and Eastern Europe. There exists relatively more data on nutritional status characterized by body mass index (BMI) and skinfold thickness measurements. Food intake has mainly been followed in smaller samples of adolescents, and or in special groups (athletes, obese, vegetarians, allergies, Romanies, pupils of special schools etc.). In the countries and/or areas with sufficient GDP and income the food intake has most often been too abundant when considering the real needs of the growing organism, especially from the point of view of energy output. The composition of the diet is not adequate, i.e. too much protein, fats, sugar etc. This situation is similar to that in Western countries, USA etc. On the other hand, adolescents in Central and Eastern Europe consume too few vegetables, fruit and milk products in their diet (i.e. low intakes of Ca, fibre and vitamin C), which is less apparent in Western countries. This is mainly due to bad eating habits and nutritional traditions in the families, but also due to the changes of the prices of the mentioned foodstuffs after political and economic changes in this part of the world. Certain nutritional deficiencies were also shown as factors increasing the health risks from the Chernobyl disaster, mainly in the Ukraine, Belorussia and certain parts of Poland.

    2013-04-01

    Luminous optical emissions accompanying streamer-based natural electric breakdown processes initiating in the mesosphere are called sprites. 489 sprite events have been observed with a TV frame rate video system in Central Europe from Sopron (47.68N, 16.58E, 230 m MSL), Hungary between 2007 and 2009. On the basis of these observations, characteristic morphological properties of sprites, i.e. basic forms (e.g. column, carrot, angel, etc.) as well as common morphological features (e.g. tendrils, glows, puffs, beads, etc.), have been identified. Probable time sequences of streamer propagation directions were associated with each of the basic sprite forms. It is speculated that different sequences of streamer propagation directions can result in very similar final sprite shapes. The number and type variety of sprite elements appearing in an event as well as the total optical duration of an event was analyzed statistically. Jellyfish and dancing sprite events were considered as special subsets of sprite clusters. It was found that more than 90% of the recorded sprite elements appeared in clusters rather than alone and more than half of the clusters contained more than one basic sprite forms. The analysis showed that jellyfish sprites and clusters of column sprites featuring glows and tendrils do not tend to have optical lifetimes longer than 80 ms. Such very long optical lifetimes have not been observed in sprite clusters containing more than 25 elements of any type, either. In contrast to clusters containing sprite entities of only one form, sprite events showing more sprite forms seem to have extended optical durations more likely. The need for further investigation and for finding theoretical concepts to link these observations to electric conditions ambient for sprite formation is emphasized.

    Objective Central and Eastern Europe has among the highest rates of renal cell cancer worldwide. Few studies have been conducted in these areas to investigate the possible role of occupational exposures in renal cell cancer etiology. The purpose of this study was to examine the association of renal cell cancer with employment in specific occupations and industries. Methods From 1999–2003, we conducted a hospital-based case-control study in seven areas of the Czech Republic, Poland, Romania and Russia. A detailed occupational history was collected from renal cell cancer cases and controls, together with information on potential confounders. Odds ratios (OR) and 95% confidence intervals (CI) of cancer risk were calculated for having ever been employed in selected jobs and industries, with follow-up analyses examining duration of employment. Results A total of 992 histologically confirmed incident renal cell cancer cases and 1,465 controls were included in the analysis. An increased risk of renal cell cancer was observed for workers in agricultural labor and animal husbandry (OR=1.43, 95% CI 1.05, 1.93), particularly among women employed as general farm workers (OR=2.73, 95% CI 1.05, 7.13). Risk gradients for agricultural work increased with longer employment. An overall increased risk of renal cell cancer was seen among architects and engineers (OR=1.89, 95% CI 1.35, 2.65), and mechanical engineers (OR=1.71, 95% CI 1.03, 2.84). Conclusions Our data suggest an association between renal cell cancer and agricultural work, particularly among female workers. PMID:19737732

    BACKGROUND AND AIMS—We investigated the influence of baseline characteristics of patients with hepatocellular carcinoma (HCC) on prognosis and developed a multivariate Cox model predicting survival. All patients were from Central Europe.
METHODS—All 245 patients seen at the Department of Gastroenterology and Hepatology at the University of Vienna, Austria, from July 1991 to March 1998 were included in this retrospective study. Nineteen different clinical characteristics and survival time from date of diagnosis were noted. Factors determining survival time were analysed by univariate and multivariate analysis using Cox proportional hazard regression models and a new classification model was constructed. The validity of this model was tested on an independent group of 89 patients, seen from April 1998 to September 1999.
RESULTS—Median survival in patients with HCC was 8.0 months. In a multivariate analysis bilirubin (>2 mg/dl), portal vein thrombosis, prothrombin time (<70%), alpha fetoprotein (>180 µg/l), tumour mass >50%, and enlarged lymph nodes were independent predictors of survival. A newly constructed Cox proportional hazard model (Vienna survival model for HCC=VISUM-HCC) identified three disease stages with different durations of survival (median survival stage 1, 15.2 months; stage 2, 7.2 months; and stage 3, 2.6 months; p=0.00001). Applying the VISUM-HCC survival model to patients in Okuda stage 2 identified subgroups with an excellent and very poor prognosis for which different treatment modalities should be offered.
CONCLUSIONS—Our patients with HCC had a poor median survival of eight months. Six easily measurable clinical variables were significant predictors of survival in patients with HCC. The new VISUM-HCC survival model may be useful for stratifying patients with HCC for various clinical treatment modalities.

    We report on a flood and earthquake risk assessment for 32 countries in Europe and Central Asia with a focus on how current flood and earthquake risk might evolve in the future due to changes in climate, population, and GDP. The future hazard and exposure conditions used for the risk assessment are consistent with selected IPCC AR5 Representative Concentration Pathways (RCPs) and Shared Socioeconomic Pathways (SSPs). Estimates of 2030 and 2080 population and GDP are derived using the IMAGE model forced by the socioeconomic conditions associated with the SSPs. Flood risk is modeled using the probabilistic GLOFRIS global flood risk modeling cascade which starts with meteorological fields derived from reanalysis data or climate models. For 2030 and 2080 climate conditions, the meteorological fields are generated from five climate models forced by the RCP4.5 and RCP8.5 scenarios. Future flood risk is estimated using population and GDP exposures consistent with the SSP2 and SSP3 scenarios. Population and GDP are defined as being affected by a flood when a grid cell receives any depth of flood inundation. The earthquake hazard is quantified using a 10,000-year stochastic catalog of over 15.8 million synthetic earthquake events of at least magnitude 5. Ground motion prediction and estimates of local site conditions are used to determine PGA. Future earthquake risk is estimated using population and GDP exposures consistent with all five SSPs. Population and GDP are defined as being affected by an earthquake when a grid cell experiences ground motion equaling or exceeding MMI VI. For most countries, changes in exposure alter flood risk to a greater extent than changes in climate. For both flood and earthquake, the spread in risk grows over time. There are large uncertainties due to the methodology; however, the results are not meant to be definitive. Instead they will be used to initiate discussions with governments regarding efforts to manage disaster risk.

    Atmospheric water in form of vapor or clouds is responsible for ˜75 % of the natural greenhouse effect and carries huge amounts of latent heat. For this reason, a best possible description of the hydrological cycle is a prerequisite for reliable climate modelling. As the stable isotopes H216O, H218O and HDO differ in vapor pressure, they are fractionated during phase changes and contain information about the formation of precipitation, evaporation from the ground, etc. Therefore, the isotopic composition of atmospheric water is an useful tracer to test and improve our understanding of the extremely complex and variable hydrological cycle in Earth's atmosphere. Within the project PalMod the isotope-enabled limited-area model COSMOiso will be used for high-resolution isotope simulations of paleo-climates. For validation with modern observations we compare 12 years of modelled isotope ratios from Central Europe to observations of the Global Network of Isotopes in Precipitation (GNIP) and to observations of isotope ratios of water vapor at different locations in Germany. We find a good agreement of modelled and observed isotope ratios in summer. In winter, we observe a systematic overestimation of modelled isotope ratios in precipitation and low-level water vapor. We relate those differences to specific circulation regimes with predominantly easterly moisture transport and the corresponding strong dependence of modelled isotope ratios on lateral boundary data. Furthermore, we investigate the dependence of modelled isotope ratios in winter on the type of isotope fractionation during surface evaporation at skin temperatures close to the freezing point.

  10. A Treasure Chest of Nanogranites: the Bohemian Massif (Central Europe)

    Despite 150 years of investigation of the Bohemian Massif (Central Europe), it is only recently that the investigation of old and new samples displayed the occurrence of tiny portions of crystallized anatectic melt in regional migmatites. These vestiges of magma, called "nanogranites", are natural probes of the partial melting processes in the crust. Original melt composition and water content can be directly analyzed after piston cylinder re-homogenization. When compared to classic re-melting experiments, nanogranites are ideal "natural" experimental charges of anatectic melt. They are encapsulated in peritectic garnet immediately after production - both phases are products of the same partial melting reaction. Sheltered inside garnet, they remain unaffected by the physico-chemical changes which affected the host migmatites during their slow cooling, unlike leucosomes and anatexis-related plutons. Five different case studies of nanogranite-bearing high-grade rocks have been identified so far: three in metapelites from the Moldanubian Zone, and two in metagranitoids from the Granulitgebirge and Orlica-Śnieżnik Dome. Their characterization provides insights into how the continental crust melts at different depths, from shallow levels to mantle depths, during different moments of its metamorphic history (prograde vs. decompressional melting). For example, the investigation and experimental re-melting of nanogranites from Grt+Ky leucogranulites (Orlica-Śnieżnik Dome) recently provided evidence of prograde melting of metagranitoids under eclogite-facies conditions (T≥875°C and P~2.7 GPa), close to the stability field of coesite. The melt generated is granitic, hydrous (6 wt% H2O) and metaluminous (ASI=1.03), and is at the moment the "deepest" glass obtained through re-homogenization of primary polycrystalline inclusions in natural rocks. This work confirms that nanogranites in migmatites 1) are a powerful tool to constrain anatexis in natural rocks, and 2) can

    The first large geological map of Central and Eastern Europe was compiled by Stanisław Staszic in the early 19th century. The map is based on the geological survey that Staszic performed in different parts of Poland and adjacent areas. In 1814, Staszic presented his ideas on the geology and mineral sources of Poland and Lithuania. In 1815, he completed the book-length descriptive analysis O ziemorodztwie Karpatów i innych gór i równin Polski przez Stanisława Staszica, which was published in Warsaw and complemented by a large geological map of Central and Eastern Europe. His later studies were compiled in a historico-philosophical treatise titled Ród ludzki (1819-1820). The complete edition of Staszic's works, Dzieła, which also included these publications, appeared over 1816-1820. The geological field survey that he performed over several years, and his study of social-economic problems enabled Staszic to draw in great detail a geological map of the Carpathians, the Central Polish Highlands, Volhynia (modern Ukraine) and the Eastern Alps, as well as the areas of the Polish-Lithuanian Lowlands, the southern coast of the Baltic Sea, Polesye (modern Belarus), Moldova, Transylvania, and Hungary. Staszic was interested in the exploration of mineral deposits, particularly in Poland, which had rock salt, copper and iron ores, and coal. In his monograph and map, he adopted a stratigraphic subdivision based on types of rock contents and organic fossils, which was a slightly modified version of Werner's classification system. The lithological legend sets five classes and 135 different types of rock, and 15 types of ore deposits, using the French names for these. In general, Staszic was an advocate of Werner's paradigm; however, he did not follow exactly the ideas of the German geologist. Staszic's fundamental work recapitulates his views on geological history of Central and Eastern Europe, and brings to an end the Enlightment period in the geology of that part of

    Hungary is situated at the point of intersection of Europe`s North-South and East-West roads. It is a country of Central Europe where, as a result of political changes of the recent past, substancial social, economic and market changes have occured. Due to its geographical situation and its historical tradition, Hungary wishes to stay in the leading position among the transforming countries of this region. DedAsz Rt. is one of the six electricity supply companies of Hungary. Our main task is to distribute and supply electrical energy to the customers in this region, in the South-West part of the country. Our supply area is 18,414 sqkms, where electricity is supplied in 27 towns and 799 villages to 665,000 customers. The history of electricity supply in this area, and also the history of our company takes a look back into 100 years. The grater part of this 100-year-long history has been extensive development, especially during the decades of socialism. That time the quality items of service could not be properly emphasized. We are aware that this period is over and the quality items should come into the limelight in the future. Hungary is a relatively small country in Europe having a significant history and, according to our hopes, it certainly has a more important future. We are convinced that the political, economic and geographical inheritance provide us with such opportunities that to exploit them is not only in our interest, but it is our duty, too. Since 1990 the Government of Hungary has comrnitted itself to transform into a market economy. In accordance with this, such new aims and goals have been formulated which harmonize with the new European recommendations. The economic endeavours have also appeared in Hungary`s new energy-policy, for example, in our new Energy Act having just been accepted recently.

    Extreme river floods have been a substantial natural hazard in Europe over the past centuries, and radiative effects of recent anthropogenic changes in atmospheric composition are expected to cause climate changes, especially enhancement of the hydrological cycle, leading to an increased flood risk. For the past few decades, however, observations from Europe do not show a clear increase in flood occurrence rate. Here we present longer-term records of winter and summer floods in two of the largest rivers in central Europe, the Elbe and Oder rivers. For the past 80 to 150 yr, we find a decrease in winter flood occurrence in both rivers, while summer floods show no trend, consistent with trends in extreme precipitation occurrence. The reduction in winter flood occurrence can partly be attributed to fewer events of strong freezing-following such events, breaking river ice at the end of the winter may function as a water barrier and enhance floods severely. Additionally, we detect significant long-term changes in flood occurrence rates in the sixteenth to nineteenth centuries, and conclude that reductions in river length, construction of reservoirs and deforestation have had minor effects on flood frequency.

However, the |T| maxima are positioned not only along the suture zone, but also in Central Europe, showing that the contributions to the EML derive also from sources placed in the Paleozoic platform with a reverse dipolar aspect. From these results it appears that the contributions responsible for the nature of this anomaly are to be reconnected first to the presence of the TESZ, which puts in contact two different platforms with different thicknesses, and also to the presence of bodies with a strong remanent component, which characterize part of the Central European crust.

    Issues of hazardous waste management are major concerns in the countries of eastern and central Europe. A National Institute of Environmental Health Sciences-supported conference was held in Prague, Czech Republic, as a part of a continuing effort to provide information and promote discussion among the countries of eastern and central Europe on issues related to hazardous wastes. The focus was on incineration as a means of disposal of hazardous wastes, with discussions on both engineering methods for safe incineration, and possible human health effects from incineration by-products. Representatives from government agencies, academic institutions, and local industries from 14 countries in the region participated along with a few U.S. and western European experts in this field. A series of 12 country reports documented national issues relating to the environment, with a focus on use of incineration for hazardous waste disposal. A particularly valuable contribution was made by junior scientists from the region, who described results of environmental issues in their countries. PMID:10090701

    Geological observations reveal the style of neotectonic near-surface stresses and deformations in central Europe. Seismic activity, focal depths and fault plane solutions of earthquakes indicate kinematic reactions within the crust. A crustal deformation model which may account for the Rhine graben systems and the associated seismotectonic block movements in Europe is presented. A computer aided tomography to gravity anomalies is used in determining the crustal stresses in central Europe. Tomographical interpretations of gravity data with respect to seismic stresses are discussed. Kinematics and dynamics are integrated to show that the measured regional stresses in central Europe are derivable from the convection generated traction on the boundary of the elastic spherical shell of the crust as inferred from satellite derived gravity data.

    The wild boar (Sus scrofa) is one of the most widely distributed mammals in Europe. Its demography was affected by various events in the past and today populations are increasing throughout Europe. We examined genetic diversity, structure and population dynamics of wild boar in Central and Eastern Europe. MtDNA control region (664 bp) was sequenced in 254 wild boar from six countries (Poland, Hungary, Belarus, Ukraine, Moldova and the European part of Russia). We detected 16 haplotypes, all known from previous studies in Europe; 14 of them belonged to European 1 (E1) clade, including 13 haplotypes from E1-C and one from E1-A lineages. Two haplotypes belonged respectively to the East Asian and the Near Eastern clade. Both haplotypes were found in Russia and most probably originated from the documented translocations of wild boar. The studied populations showed moderate haplotype (0.714±0.023) and low nucleotide diversity (0.003±0.002). SAMOVA grouped the genetic structuring of Central and Eastern European wild boar into three subpopulations, comprising of: (1) north-eastern Belarus and the European part of Russia, (2) Poland, Ukraine, Moldova and most of Belarus, and (3) Hungary. The multimodal mismatch distribution, Fu's Fs index, Bayesian skyline plot and the high occurrence of shared haplotypes among populations did not suggest strong demographic fluctuations in wild boar numbers in the Holocene and pre-Holocene times. This study showed relatively weak genetic diversity and structure in Central and Eastern European wild boar populations and underlined gaps in our knowledge on the role of southern refugia and demographic processes shaping genetic diversity of wild boar in this part of Europe.

    In central Europe, ammonium sulphate and ammonium nitrate make up a large fraction of fine particles which pose a threat to human health. Most studies on air pollution through particulate matter investigate the influence of emission reductions of sulphur- and nitrogen oxides on aerosol concentration. Here, we focus on the influence of ammonia (NH3) emissions. Emission scenarios have been created on the basis of the improved ammonia emission parameterization implemented in the SMOKE for Europe and CMAQ model systems described in part I of this study. This includes emissions based on future European legislation (the National Emission Ceilings) as well as a dynamic evaluation of the influence of different agricultural sectors (e.g. animal husbandry) on particle formation. The study compares the concentrations of NH3, NH4+, NO3 -, sulphur compounds and the total concentration of particles in winter and summer for a political-, technical- and behavioural scenario. It was found that a reduction of ammonia emissions by 50% lead to a 24% reduction of the total PM2.5 concentrations in northwest Europe. The observed reduction was mainly driven by reduced formation of ammonium nitrate. Moreover, emission reductions during winter had a larger impact than during the rest of the year. This leads to the conclusion that a reduction of the ammonia emissions from the agricultural sector related to animal husbandry could be more efficient than the reduction from other sectors due to its larger share in winter ammonia emissions.

  20. Have “new” methods in medical education reached German-speaking Central Europe: a survey

    Background Simulation-based-training (SBT) in the education of health professionals is discussed as an effective alternative for knowledge and skills enhancement as well as for the establishment of a secure learning environment, for learners and patients. In the Anglo-American region, SBT and simulation and training centers (STC) are numbered as standard for medical training. In German-speaking Central Europe, priority is still given to the establishment of SBT and STC. The purpose of this study was (i) to survey the status quo relating to the existence and facilities of simulation and training centers at medical universities in German-speaking Central Europe and (ii) the evaluation of training methods, especially in the area of emergency medicine skills. Methods All public and private medical universities or medical faculties in Germany (36), Austria (4) and German-speaking Switzerland (3) were interviewed. In the survey, information regarding the existence and facilities of STCs and information with regards to the use of SBT in the area of emergency medicine was requested. The questions were partly posed in a closed-ended-, in an open-ended- and in a multiple choice format (with the possibility of selecting more than one answer). Results Of a total of 43 contacted medical universities/medical faculties, 40 ultimately participated in the survey. As decisive for the establishment of a STC the potential to improve the clinical-practical training and the demand by students were listed. Obligatory training in a STC during the first and sixth academic year was confirmed only by 12 institutions, before the first invasive procedure on patients by 17 institutions. 13 institutions confirmed the use of the STC for the further training of physicians and care-staff. Training for the acute care and emergency medicine skills in the field of pediatrics, for the most part, occurs decentralized. Conclusions New methods in medical training have reached German-speaking Central

    An interdisciplinary study of a small sedimentary basin at Neumark Nord 2 (NN2), Germany, has yielded a high-resolution record of the palaeomagnetic Blake Event, which we are able to place at the early part of the last interglacial pollen sequence documented from the same section. We use this data to calculate the duration of this stratigraphically important event at 3400 ± 350 yr. More importantly, the Neumark Nord 2 data enables precise terrestrial–marine correlation for the Eemian stage in central Europe. This shows a remarkably large time lag of ca. 5000 yr between the MIS 5e ‘peak’ in the marine record and the start of the last interglacial in this region. PMID:26523075

    The beginning of the 21st century was marked by a number of severe summer floods in Central Europe associated with extreme precipitation (e.g., Elbe 2002, Oder 2010 and Danube 2013). Extratropical storms, known as Vb-cyclones, cause summer extreme precipitation events over Central Europe and can thus lead to such floodings. Vb-cyclones develop over the Mediterranean Sea, which itself strongly warmed during recent decades. Here we investigate the influence of increased Mediterranean Sea surface temperature (SST) on extreme precipitation events in Central Europe. To this end, we carry out atmosphere model simulations forced by average Mediterranean SSTs during 1970-1999 and 2000-2012. Extreme precipitation events occurring on average every 20 summers in the warmer-SST-simulation (2000-2012) amplify along the Vb-cyclone track compared to those in the colder-SST-simulation (1970-1999), on average by 17% in Central Europe. The largest increase is located southeast of maximum precipitation for both simulated heavy events and historical Vb-events. The responsible physical mechanism is increased evaporation from and enhanced atmospheric moisture content over the Mediterranean Sea. The excess in precipitable water is transported from the Mediterranean Sea to Central Europe causing stronger precipitation extremes over that region. Our findings suggest that Mediterranean Sea surface warming amplifies Central European precipitation extremes. PMID:27573802

    The flexible and cheap labour that European “post-industrial” economies are in need of is often facilitated by undeclared labour. The undocumented migrant, from his/her part, relatively easily finds work that suits his -- at least initial -- plans. What lies behind this nexus between irregular migration and informal economy? To what extent can this nexus be attributed to the structural features of the so-called “secondary”, as opposed to “primary”, labour market? And how does migration policy correlate with this economic context and lead to the entrapment of migrants in irregularity? Finally, can this vicious cycle of interests and life-strategies be broken and what does the experience of the migrants indicate in this respect? This paper addresses these questions via an exploration of the grounds upon which irregular migration and the shadow economy complement each other in southern Europe (SE) and central and Eastern Europe (CEE) (two regions at different points in the migration cycle). In doing so, the dynamic character of the nexus between informal economy and irregular migration will come to the fore, and the abstract identity of the “average” undocumented migrant will be deconstructed.

  9. Diet and Mobility in the Corded Ware of Central Europe

    2016-01-01

    Isotopic investigations of two cemetery populations from the Corded Ware Culture in southern Germany reveal new information on the dating of these graves, human diet during this period, and individual mobility. Corded Ware Culture was present across much of temperate Europe ca. 2800–2200 cal. BC and is represented by distinctive artifacts and burial practices. Corded Ware was strongly influenced by the Yamnaya Culture that arose in the steppes of eastern Europe and western Eurasia after 3000 BC, as indicated by recent aDNA research. However, the development of CW on different chronological and spatial scales has to be evaluated. Examination of the CW burials from southern Germany supports an argument for substantial human mobility in this period. Several burials from gravefields and larger samples from two large cemeteries at Lauda-Königshofen "Wöllerspfad" and at Bergheinfeld “Hühnerberg” contributed the human remains for our study of bone and tooth enamel from the Corded Ware Culture. Our results suggest that Corded Ware groups in this region at least were subsisting on a mix of plant and animal foods and were highly mobile, especially the women. We interpret this as indicating a pattern of female exogamy, involving different groups with differing economic strategies. PMID:27223117

    Migration exposes people to a number of risks that threaten their health, including those related to psychosocial health. Self-perceived health is usually the main indicator used to assess psychosocial health. Electronic databases were used to examine the literature on the psychosocial health of immigrants in Europe and of North Africans living in their own countries. Immigrants of various ethnic groups show a similar risk of psychosocial disorders but generally present a higher risk than the local population. This risk is related to gender (being higher in women), poor socio-economic status and acculturation, discrimination, time elapsed since migration and age on arrival in the new country. Although the stressors and situations the different ethnic groups experience in the host country may be shared, the way they deal with them may differ according to cultural factors. There is a need to collect detailed data on psychosocial health among the various immigrant groups in Europe, as well as to monitor this aspect in North African residents who lack access to specific services.

  11. "out of The Cold": On Late Neanderthal Population Dynamics In Central Europe

    Jöris, O.

    During the last several years, analyses of fossil Neanderthal DNA have shown not only the degree to which the genetic fingerprints of Neanderthals differ from those of anatomically modern humans, but have also lent credibility to the hotly debated "Out- of-Africa" hypothesis. Perhaps more important than the observed genetic differences is the fact that Neanderthals - according to their reconstructed DNA sequences - were genetically highly homogeneous, indicating rapid population growth that may have followed a demographic 'bottleneck' during the first cold maximum (CM-1 = second part of OIS 4) of the last glacial, some 60 to 70 ka ago. Central European Middle Palaeolithic sites characterised by broad spectra of bifacially-worked tools, namely different forms of backed knives ("Keilmesser") com- monly attributed to Neanderthals, fall within the age-range 85 and 45 ka calBP and thus both pre- and post-date the proposed 'bottleneck' that occurred during CM-1. Di- rectly comparable sites dating within this critical period are lacking. Based on strati- graphic, palaeoenvironmental, and radiometric evidence, a series of sites can tenta- tively be age-calibrated with the high-resolution GISP2 Greenland ice core record of last glacial climate change. With the aid of improved chronological frameworks and additional palaeoenvironmen- tal information (e.g. glacier mass balance models), we have developed a three-step model with which to investigate this period. We begin with (1) pre-CM-1 populations in Central and northern Central Europe which (2) were forced into southern Euro- pean refugia (i.e. SW France and the Pannonian Basins) by the rapid expansion of the northern hemispheric ice-cover at the beginning of CM-1 (a process that could be named 'preglacial dislocation'). Finally, some 10 ka later, their descendants may have re-occupied the southern part of Central Europe during the climatic amelioration (OIS 3) following CM-1.

    Hantaviruses are considered to be emerging viruses due to their increasing significance as human pathogens and their cyclic reappearance during outbreaks. Central Europe is an important endemic region for hantavirus infections. Reflecting the presence of all relevant small mammals serving as reservoir hosts, close to all recognized European hantaviruses occur also in Central Europe. Important human pathogens, Puumala and Dobrava-Belgrade viruses, are present and cause hemorrhagic fever with renal syndrome of various severities. Moreover, several of the newly recognized shrew- and mole-borne hantaviruses are present. In this review, we summarize current data on molecular detection of hantaviruses in reservoir hosts as well as on molecular epidemiology of human hantavirus infections in Central Europe.

    An increase of hydro-climatic extremes can be observed worldwide and is challenging national and regional risk management and adaptation plans. Our study presents and discusses possible trends in climate drivers and hydro-climatic extremes in Europe observed and under future climate conditions. In a case study for Germany, impacts of different regional climate scenario ensembles are compared. To this end, a hydrological model was applied to transform the scenarios data into river runoff for more than 5000 river reaches in Germany. Extreme Value Distributions have been fitted to the hydrographs of the river reaches to derive the basic flood statistics. The results for each river reach have been linked to related damage functions as provided by the German Insurance Association considering damages on buildings and small enterprises. The robust result is that under scenario conditions a significant increase in flood related losses can be expected in Germany, while also the number of low flow events may rise.

  14. Hungarian travertine: a historic and current stone resource of Central Europe

    2013-04-01

    Travertine is a widespread dimension stone that was used worldwide in monuments. The best known examples are known from the Roman Empire from Italy, where this porous stone belonged to one of the favourite stone types. Ancient quarries of Tivoli provided material to major construction works to Rome. Other occurrences belonging to the Roman Empire outside of Rome were also used by the Romans. Some of the most important European deposits are known from Hungary. Exploitable travertine layers are found at many places in Hungary but at least two major areas were actively quarried by the Romans. One major deposit was not far away from the provincial capital of Roman Pannonia - called Aquincum, which currently forms a part of Budapest, while the other even larger occurrence is at Süttő, at the riverside of Danube some 50 km NE from the past capital. River Danube provided an excellent pathway of transport ting stone to the capital. Evidences indicate that quarrying activity in Süttő area has already begun during the 1st century BC and the travertine has been exploited with some interruptions since then. The present day quarries form the parts of the largest active dimension quarry system of Hungary. The exposed very thick banks (3 to 4m) of travertine were deposited from lukewarm springs during the Pleistocene period. Various types of travertine were used for constructing Roman aqueducts, fortresses, amphitheatre until the 4th century AD and were also transported to other parts of that Roman Province which extended to the present territory of Hungary, Austria, Slovenia and Croatia. Although the use of travertine has significantly decreased after the fall of Roman Empire in Central Europe and in Hungary, the presence of this stone was also documented from numerous Gothic and Baroque buildings from the area. The use of this stone became more popular again in the Carpathian Basin, when major constructions of larger cities such as Bratislava, Vienna or Budapest accelerated

    With the rapid growth in the no. of seismic stations globally, manual data processing for routine analysis as well as determination of seismic observables becomes more and more impractical. Therefore, automated schemes are inevitable to handle these large data volumes. For surface wave tomography, phase velocity dispersion curves of fundamental mode surface waves yield information on the isotropic as well as anisotropic structure of the crust and upper mantle. We measure inter-station phase velocity dispersion curves through cross correlation of vertical component (Rayleigh wave) and transverse component (Love wave) seismograms. We have developed a scheme to automate this well established inter-station method, which automatically selects the smooth parts of observed phase velocity dispersion curves, and thus obtain path average phase velocity dispersion curve of each inter-station path. After testing various parameters for automation of the procedure we finally confined the method to three parameters only, namely (1) difference of the measured phase velocity curve from a background model, (2) a smoothness constraint and (3) a length criterion. We performed rigorous tests to optimize the parameters and obtained optimal values of these three parameters. We successfully applied the method to more than one hundred thousand inter station paths in central and northern Europe which involved more than one million cross correlations on 20 years of the data of the permanent networks. The method was also tested on temporary deployments e.g. TOR, PASSEQ, SVEKALPKO etc, across Europe. After inversion of the fundamental mode phase velocity dispersion curves for both Rayleigh and Love waves, we obtain high resolution anisotropic phase velocity maps for periods between 10 and 250 seconds with a lateral resolution between about 50 to 100 kilometers. Well known features of upper mantle structure in central Europe are well resolved in our phase velocity maps. Distinct differences

    The international pattern of obesity is only partly understood. While in developed countries the association between education and obesity is inverse, in the developing world social distribution of obesity is less predictable. We examined obesity patterns in three countries of Central and Eastern Europe (CEE): Russia, Poland and the Czech Republic, middle-income post-communist countries undergoing social and economic transition. The prevalence of obesity was inversely associated with education of individuals in our three samples of Central and Eastern European populations. In agreement with previous findings, the inverse socioeconomic gradient was more pronounced in the Czech Republic and Poland, countries with higher Gross National Product (GNP) than Russia. In addition, obesity was more common in Russian women than in Czech or Polish women while Russian men were less obese than Czech or Polish men. These findings are consistent with the hypothesis that the social gradient in obesity differs between populations--it is more likely to find a reverse association between socioeconomic position and prevalence of obesity in the more westernized countries with higher population income.

    New finds of teeth and mandibles of Anchitheriomys from the Hambach opencast lignite mine in Northwest Germany and the first detailed descriptions of other mandibles from South Germany and Switzerland allow a review of the Central European specimens of this rare beaver genus. The metric variation of cheek teeth and especially the great differences in dimensions of incisors can be much better assessed. The observed range in size can be attributed to ontogenetic changes, and all material is assigned to Anchitheriomys suevicus. Stratigraphically, this species is restricted to the early middle Miocene, European Mammalian Neogene biozones MN 5-6.

    Central Europe was characterized by a humid-temperate climate in the 20th century. Climate change projections suggest that climate in this area will shift towards warmer temperatures by the end of the 21st century, while projected precipitation changes are highly uncertain. Here we show that the 2015 summer rainfall was the lowest on record since 1901 in Central Europe, and that climate models that perform best in the three driest years of the historical time period 1901–2015 project stronger drying trends in the 21st century than models that perform best in the remaining years. Analyses of precipitation and derived soil moisture reveal that the 2015 event was drier than both the recent 2003 or 2010 extreme summers in Central Europe. Additionally there are large anomalies in satellite-derived vegetation greenness. In terms of precipitation and temperature anomalies, the 2015 summer in Central Europe is found to lie between historical climate in the region and that characteristic of the Mediterranean area. Even though the models best capturing past droughts are not necessarily generally more reliable in the future, the 2015 drought event illustrates that potential future drying trends have severe implications and could be stronger than commonly assumed from the entire IPCC AR5 model ensemble.

  14. Crustal structure of the Pannonian-Carpathian region, Central Europe, from ambient noise tomography

    The Pannonian Basin of Central Europe is a major extensional basin surrounded by the Carpathian Mountains. During the evolution of the Carpathian-Pannonian region, extension of the crust and lithosphere created several inter-related basins of which the Pannonian basin is the largest. Imaging the seismic velocity structure of the crust and the upper mantle may help us understand the structure and geodynamic evolution of this part of central Europe. Here, we use ambient noise tomography to investigate the crust and uppermost mantle structure in the region. We have collected and processed continuous data from 56 temporary stations deployed in the Carpathian Basins Project (CBP) for 16 months (2005-2007) and 41 permanent broadband stations; this dataset enables the most well-resolved images of the S-wave structure of the region yet obtained. We computed the cross-correlation between vertical component seismograms from pairs of stations and stacked the correlated waveforms over 1-2 years to estimate the Rayleigh wave Green’s function. Frequency-time analysis is used to measure the group velocity dispersion curves, which are then inverted for the group velocity maps. Our 4-10 s group velocity maps exhibit low velocity anomalies which clearly defined the major sediment depo-centers in the Carpathian region. A broad low velocity anomaly in the center of the 5 s group velocity map can be associated with the Pannonian Basin, whereas an anomaly in the southeastern region is related to the Moesian platform. Further east, the Vienna Basin can also be seen on our maps. A fast anomaly in the central region can be associated with the Mid-Hungarian line. At periods from 18 to 24 seconds, group velocities become increasingly sensitive to crustal thickness. The maps also reveal low-velocity anomalies associated with the Carpathians. The low velocity anomalies are probably caused by deeper crustal roots beneath the mountain ranges which occur due to isostatic compensation. CBP

    Blackbirds (Turdus merula) and song thrushes (Turdus philomelos) were found to carry 95% of all spirochete-infected tick larvae among 40 bird species captured in Central Europe. More than 90% of the infections were typed as Borrelia garinii and Borrelia valaisiana. We conclude that thrushes are key players in the maintenance of these spirochete species in this region of Central Europe.

    On 29 August 2014 a fissure eruption began in Holuhraun, Northeastern Iceland, associated with increased volcanic activity in the Bárdarbunga system. For more than 150 days, the eruption released large quantities of SO2 into the atmosphere affecting not only the local Icelandic air quality, but also leading to periods of increased ambient SO2 concentrations in parts of mainland Europe. During the second half of September, significant amounts of SO2 were rapidly transported southward by favourable meteorological conditions and several countries in Central Europe experienced high ground-level SO2 concentrations. The measured concentrations reached and even exceeded the EC directive health thresholds. In this work, we evaluate the air quality effects in Europe during this targeted period using both ground-based and satellite observations (GOME2B and OMI) as well as dispersion modelling with the Lagrangian particle model FLEXPART. We estimate the volcanic SO2 source emissions by comparing the satellite observations with atmospheric transport model simulations in an inverse modelling approach. The estimated source term is evaluated against independent ground-based observational data (e.g. MAX-DOAS, Brewer) and used as emission term in dispersion model forecasts for evaluating the air quality effects in Europe. In addition, the potential use of air quality data to perform the source term estimation by inversion with ground-based data will also be investigated.

  17. Flesh flies (Diptera: Sarcophagidae) colonising large carcasses in Central Europe.

    Sarcophagidae are an important element of carrion insect community. Unfortunately, results on larval and adult Sarcophagidae from forensic carrion studies are virtually absent mostly due to the taxonomic problems with species identification of females and larvae. The impact of this taxon on decomposition of large carrion has not been reliably evaluated. During several pig carcass studies in Poland, large body of data on adult and larval Sarcophagidae was collected. We determined (1) assemblages of adult flesh flies visiting pig carrion in various habitats, (2) species of flesh flies which breed in pig carcasses, and (3) temporal distribution of flesh fly larvae during decomposition. Due to species identification of complete material, including larvae, females, and males, it was possible for the first time to reliably answer several questions related to the role of Sarcophagidae in decomposition of large carrion and hence define their forensic importance. Fifteen species of flesh flies were found to visit pig carcasses, with higher diversity and abundance in grasslands as compared to forests. Sex ratio biased towards females was observed only for Sarcophaga argyrostoma, S. caerulescens, S. similis and S. carnaria species group. Gravid females and larvae were collected only in the case of S. argyrostoma, S. caerulescens, S. melanura and S. similis. Sarcophaga caerulescens and S. similis bred regularly in carcasses, while S. argyrostoma was recorded only occasionally. First instar larvae of flesh flies were recorded on carrion earlier or concurrently with first instar larvae of blowflies. Third instar larvae of S. caerulescens were usually observed before the appearance of the third instar blowfly larvae. These results contest the view that flesh flies colonise carcasses later than blowflies. Sarcophaga caerulescens is designated as a good candidate for a broad forensic use in Central European cases.

  18. Trends in the mortality effects of hot spells in central Europe: adaptation to climate change?

    Europe has recently been affected by several long-lasting and severe heat waves, particularly in July-August 2003 (western Europe), June-July 2006 (central Europe), July 2007 (southeastern Europe) and July 2010 (western Russia). The heat waves influenced many sectors of human activities, with enormous socio-economic and environmental impacts. With estimated death tolls exceeding 50,000, the 2003 and 2010 heat waves were the worst natural disasters in Europe over the last 50 years, yielding an example of how seriously may also high-income societies be affected by climate change. The present study examines temporal changes in mortality associated with spells of large positive temperature anomalies (hot spells) in the population of the Czech Republic (around 10 million inhabitants, central Europe). Declining trends in the mortality impacts since 1986 are found, in spite of rising temperature trends. The findings remain unchanged if possible confounding effects of within-season acclimatization to heat and the mortality displacement effect are taken into account, and they are similar for all-cause mortality and mortality due to cardiovascular diseases. Recent positive socio-economic development, following the collapse of communism in central and eastern Europe in 1989, and better public awareness of heat-related risks are likely the primary causes of the declining vulnerability in the examined population (Kyselý and Plavcová, 2012). The results are also consistent with those reported for other developed regions of the world (the US, western Europe, Australia) and suggest that climate change may have relatively little influence on heat-related deaths, since changes in other factors that affect vulnerability of the population are dominant instead of temperature trends. It is essential to better understand the observed non-stationarity of the temperature-mortality relationship and the role of adaptation and its limits, both physiological and technological, and to address

  19. Glacial Isostatic Adjustment as a key to understand the neotectonics of northern Central Europe

    NASA Astrophysics Data System (ADS)

    2014-05-01

    Northern Central Europe is generally regarded as aseismic, however, several historic earthquakes with intensities of up to VII occurred in this region during the last 1200 years (Leydecker, 2009). In a pilot study we analysed the Osning Thrust, which is a one of the major Mesozoic fault zones in northern Central Europe. Several soft-sediment deformation structures like fault-arrays and a sand volcano developed in aeolian sediments, were caused by earthquakes along the Osning Thrust. The growth-strata of faults was dated with the OSL method and showed that the deformation took place between 15.9 ± 1.6 to 13.1 ± 1.5 ka (Brandes et al., 2012, Brandes & Winsemann, 2013). Numerical simulations support the results regarding the timing of the the seismicity and imply that the Late Pleistocene activity of the Osning Thrust was an effect of glacial isostatic adjustment (Brandes et al., 2012). In a second step we analysed more faults in northern Central Europe. It is evident that the historic seismicity was concentrated along major reverse faults that formerly played an important role during a tectonic contraction phase that effected Central Europe in the Late Cretaceous. Between these faults, the seismic activity was almost absent. Many of the historic earthquakes concentrated for a certain time along one fault and there is even evidence for distinct earthquake clusters in northern Central Europe e.g. along the Osning Thrust, the Aller Valley Fault and the Tornquist Zone. The spatial and temporal distribution of earthquakes (clusters that shift from time to time) implies that northern Central Europe behaves like a typical intraplate tectonic region. To analyse, if the faults that show pronounced historic seismicity are postglacial faults, we used the Fault Stability Margin (FSM), which is described in more detail in Wu & Hasegawa (1996). The Fault Stability Margins for the major reverse faults that showed historic seismicity in northern Central Europe reach the δFSM=0

    We combine paleoseismic trench and cosmogenic dating results to study the late Pleistocene-Holocene history of morphologically pronounced NW-SE trending Sudetic Marginal Fault (SMF) situated at the northeastern limit of the Bohemian Massif in central Europe. Eighteen trenches were excavated at the Bila Voda site to study 3D distribution of a beheaded alluvial fan on the NE block of the fault and to find the offset "feeder channel" that sourced the deposits. We interpret a small drainage of about 40-60 m to the SE of the fan apex as the feeder channel. A 2.5 m depth profile was collected for cosmogenic exposure dating from a well-preserved part of the fan. Using a simple model that accounts for pre-depositional exposure (inheritance) and assuming no surface erosion, 10Be concentrations are well-fit with an apparent exposure age of ~12 ka. However, this is a minimum limiting age if the surface was eroded by gelifluction in the late Pleistocene. Assuming a ~25 ka OSL age for the base of the fan apex it gives a left-lateral slip rate of ~2 mm/yr. As the Holocene deposits do not show significant displacement, most of the recorded slip took place during Late Pleistocene with corresponding slip rate of 2.8 to 3.5 mm/yr. Bila Voda site lies ~150 km south from the Late Pleistocene Weichselian maximum (~20 ka) ice-sheet front. Thus, we hypothesize that the slip rate acceleration was due to ice-loading and subsequent unloading during deglaciation. To test this, we calculated the stress induced in the lithosphere from ablation of the Weichselian ice sheet modeled as a flexing elastic plate. Preliminary modeling results indicate that complete deglaciation alters the stress field such that it would inhibit left lateral failure on the SMF, consistent with observations suggesting no slip occurred during the Holocene. Although the SMF is ~150 km from the Weichselian ice sheet front, it is well within the flexural rebound area of the ice sheet, causing normal stress on the SMF to

    Catastrophe models are widely used in reinsurance risk assessment from natural perils. In this context Guy Carpenter, a reinsurance intermediary, has developed a probabilistic hail model for Central Europe. As part of the hazard development, Guy Carpenter has tasked meteorologists at nowcast GmbH to identify historic hail patterns and individual hail storm tracks over an 8-year period from a continuous lightning dataset, issuing from their lightning detection system, "LINET". Based on historic hail footprints provided by nowcast GmbH, Guy Carpenter has developed a stochastic event generator in order to compute a catalogue consisting of synthetic, but meteorologically reasonable events, representing an 800-year history. The goal of stochastic event generation is to extend the observed hail history to extreme hail scenarios that could cause catastrophic losses to insurance portfolios and to quantify corresponding storm probabilities. Reflecting geographical dependencies, the method uses key attributes of the historic hail tracks and footprints, such as the storm track, length and bearing direction, footprint centre point and storm genesis date. A bootstrapping technique was used to associate simulated hail footprints with a likely storm track, based on historic distributions. The poster shows work in progress on the event set generation results, the computed geographic hazard maps and validation of the frequency and intensity assumptions, using data from nowcast GmbH, the European Severe Storms Laboratory (ESSL) and spatial statistics on insurance claims information.

    The paper brings insights on the process of e-health development in countries of Central and Eastern Europe, which joined European Union in 2004 years. The main part of the activities resulting in this review were carried out within the eHealth European Research Area (eHealth ERA) project established under the EU 6. Framework Programme. The research team involved in the project activities in the Centre of Innovation, Technology Transfer and University Development, Jagiellonian University focused the inquiries on the six countries: Poland, Czech Republic, Slovakia, Hungary, Lithuania and Latvia. The tool for data collection elaborated by the STAKES, Finland was applied. The main areas covered within the analysis included: health system characteristics, e-health policies definition process and deployment, specific activities in e-health subdomain as well as research and development programmes held in European countries. It seems that general background and intensive process of system and economy transformation was key factor influencing greatly the perception and status of the e-health domain in these countries. The opportunities related to the inclusion in the European Union was another essential factor bringing additional important impact on the e-health formation. All these countries started painful reform in early 90s after the fall of the communist governments. The health care system in general was not the prime benefactors of these changes. PMID:17894192

    This paper reports evidence of Pu isotopes in the lower part of the troposphere of Central Europe. The data were obtained based on atmospheric aerosol fraction samples collected from four places in three countries (participating in the informal European network known as the Ring of Five (Ro5)) forming a cell with a surface area of about 200,000km(2). We compared our original data sets from Krakow (Poland, 1990-2007) and Bialystok (Poland, 1991-2007) with the results from two other locations, Prague (Czech Republic; 1997-2004) and Braunschweig (Germany; 1990-2003) to find time evolution of the Pu isotopes. The levels of the activity concentration for (238)Pu and for ((239+240))Pu were estimated to be a few and some tens of nBqm(-3), respectively. However, we also noted some results were much higher (even about 70 times higher) than the average concentration of (238)Pu in the atmosphere. The achieved complex data sets were used to test a new approach to the problem of solving mixing isotopic traces from various sources (here up to three) in one sample. Results of our model, supported by mesoscale atmospheric circulation parameters, suggest that Pu from nuclear weapon accidents or tests and nuclear burnt-up fuel are present in the air.

  5. Holocene floodplain sedimentation in Central Europe and the impact of historic mining

    2008-12-01

    In most parts of Europe, the Late Quaternary evolution of floodplain environments is the result of interactions between natural and human factors. Land-use changes, during the Neolithic, such as deforestation and the introduction of agriculture affected the stratigraphy of river sediments due to soil erosion on the slopes and alluvial deposition of fine-grained sediments in the floodplains. Beside agriculture mining must be also considered as an important factor controlling the Late Holocene floodplain evolution. Prehistoric and historic metal mining activities caused landscape degradation, such as vegetation clearance which increased the rate of soil erosion especially via hillslope gullying. During the Late Middle Ages, East Bavaria, Germany and the Vils River Valley in particular were one of the leading regions for the iron industry in Central Europe. Two hundred ironworks used 378 000 m3 of wood per annum allowing the production of 9000 tons of iron during the "golden age" of mining in the 15th century. Since the late 19th century the role of the iron industry in East Bavaria has decreased rapidly. The intensive historic mining activities on the Vils River floodplain should have affected the river structure as well as the fluvial dynamics, in particular via the construction of ironworks and associated weirs. Further floodplain sedimentation is thought to have been influenced by the mining-induced soil erosion occurring in the catchment and primary on the slopes. The nature and extent of these changes have not been investigated to date. Analysis of 288 percussion drillings with depths of up to 7 m and a 120 m long excavator section provide new and detailed information on the Late Pleistocene to Late Holocene floodplain evolution. The generalised sequence of the Vils River floodplain is built up of five units representing facies of different genesis (rock/saprolite, gravel, sand, loam, peat) which are identified by physical, chemical and mineralogical parameters

    Study of mantle conductivity beneath the Trans European Suture Zone (TESZ) in Central Europe is the subject of the international CEMES project. The study includes investigations of the mid-mantle conductive layer, which are based on unique data sets from European geomagnetic observatories. Results obtained by few investigators for individual observatories indicate that depths up to the mid-mantle conductive layer are increasing generally from the North to South beneath Europe. To investigate the phenomenon in more details, local magnetovariation responses published by Roberts (1984), Schultz &Larsen (1987), Olsen (1998) and Semenov (1998) have been collected for 35 European geomagnetic observatories with periods from 6 hours to as long as available. The data collected for each observatory have been extended by using the ultra-long period responses obtained for the Europe-Asia region up to the global 11-year period (Semenov &Jozwiak, 1999). For all observatories, the data have been inverted by means of the 1D spherical inversion based on the stochastic method (Jozwiak, 2001). The mid-mantle conductive layer has been detected for all observatories at varying depths. The mantle geoelectrical structures are presented as the schematic maps of depths with constant conductance beneath whole Europe. The conclusion mentioned above has been generally confirmed by the data with much wider period range and great number of observatories: depths are found to increase from 500-600 km beneath the Baltic Shield down to 750-800 km beneath the southern and west-southern regions of Europe. Detailed results obtained beneath the TESZ are subject of discussion for Central Europe.

    Two species of arbovirus vector, Culex torrentium and Culex pipiens (Diptera: Culicidae), occur in several European countries, but difficulties in their accurate identification and discrimination have hampered both detailed and large-scale distribution and abundance studies. Using a molecular identification method, we identified to species 2559 larvae of Cx. pipiens/torrentium collected from 138 sites in 13 European countries ranging from Scandinavia to the Mediterranean coast. In addition, samples of 1712 males of Cx. pipiens/torrentium collected at several sites in the Czech Republic were identified to species based on the morphology of their hypopygia. We found that the two species occur together in large areas of Europe, and that Cx. torrentium dominates in northern Europe and Cx. pipiens dominates south of the Alps. The transition in dominance occurs in central Europe, where both species are roughly equally common. There was a strong correlation between the length of the growing season at different sites and occurrences of the two species. As the growing season increases, the proportion and detection of Cx. torrentium decrease, whereas those of Cx. pipiens increase. The present findings have important consequences for the interpretation of the results of studies on major enzootic and link-vectors of mosquito-borne bird-associated viruses (i.e. Sindbis, West Nile and Usutu viruses), especially in central Europe and Scandinavia.

    Lightning activity in storms with overshooting tops and hail-producing storms over Central Europe is studied, in order to find typical lightning characteristics that can be useful in nowcasting of the severity of the storm and its ability to produce hail. The first part of the study gives the analysis of lightning activity in thunderstorms with overshooting tops (OT) for the warm part of the year (May-September) from 2009 to 2010 over central and southeastern Europe. Deep convective clouds with OT were detected in Meteosat Second Generation (MSG) Spinning Enhanced Visible and Infrared Imager (SEVIRI) data, using methods based on the infrared window (IRW, 10.8 μm) channel and absorption channels of water vapor (WV, 6.2 μm) and ozone (O3, 9.7 μm) in the form of brightness temperature differences. The locations and times of the detected OT were compared to the distribution and types of lightning strokes, which were provided by the LINET Lightning Location System. The results show that the spatial distribution of lightning generally coincides with the spatial distribution of the detected OT. The largest numbers of lightning strokes and OT were found in western Hungary, southeastern Austria, northeastern Slovenia and the northern Adriatic. The largest number of OT occurred between 1600 and 1800 UTC, whereas from 0600 to 1000 UTC OT detections were rather rare. Lightning activity showed a similar temporal distribution, with an increase in lightning activity evident at or close to the time of the OT detections. At the time of and close to the location of the OT, the lightning was found to occur well above the tropopause and was clearly related to the OT of cumulonimbus clouds. In the second part of the study, lightning characteristics are studied for 35 events of hail-producing thunderstorms over Croatia in the summer months (May to September), from 2008 to 2012. The lightning distribution, also registered by LINET, was compared to hail parameters based on measurements

  9. How high is infant mortality in central and eastern Europe and the commonwealth of independent states?

    2005-03-01

    This paper examines the measurement of infant mortality in the countries of Central and Eastern Europe and the Commonwealth of Independent States (CIS). There are worrying indications that official infant mortality counts, based on administrative data, may understate the true gravity of the problem in 15 countries in the region, including 11 out of 12 CIS countries, and 4 countries in South Eastern Europe. In the case of eight CIS countries in the Caucasus and Central Asia plus Romania, the evidence is strongest, not least because surveys that allow independent estimation of infant mortality have been carried out there. In the case of the remaining six countries, the evidence is more circumstantial, and based on inconsistencies within the official data themselves, combined with information on how live births are defined. However, we find also that surveys are rather blunt instruments, and that the confidence intervals that surround estimates from these surveys are often large. PMID:15764133

    A superposed epoch analysis during late winter zonal wind reversals was carried out from 18 year observation series (1963 to 1980) of the meridional geopotential height gradient in the 30 mb level (latitude mean) and of the ozone content over central Europe. Experimental data suggest that if planetary waves are responsible for the additional meridional ozone transport during stratospheric warmings, this transport has to take place at heights other than those up to the ozone maximum in the middle latitudes.

  11. Future changes in Central Europe heat waves expected to mostly follow summer mean warming

    Daily output from the PRUDENCE ensemble of regional climate simulations for the end of the twentieth and twenty-first centuries over Europe is used to show that the increasing intensity of the most damaging summer heat waves over Central Europe is mostly due to higher base summer temperatures. In this context, base temperature is defined as the mean of the seasonal cycle component for those calendar days when regional heat waves occur and is close, albeit not identical, to the mean temperature for July-August. Although 36-47% of future Central Europe July and August days at the end of the twenty-first century are projected to be extreme according to the present day climatology, specific changes in deseasonalized heat wave anomalies are projected to be relatively small. Instead, changes in summer base temperatures appear much larger, clearly identifiable and of the same order of magnitude as changes in the whole magnitude of heat waves. Our results bear important consequences for the predictability of central European heat wave intensity under global warming conditions.

    Increasing environmental pressures worldwide, including East Central Europe are placing greater emphasis on NO{sub x} emission controls in utility power plants. Western Europe, Japan and the U.S. have significant experience in applying NO{sub x} controls, especially in boilers firing hard coal. Some countries in Europe (i.e., Germany and Austria), have gained experience in applying NO{sub x} controls in boilers firing low-rank coal. This experience can be applied to East Central European countries in providing the basis for planning NO{sub x} control projects, suggesting cost-effective solutions, and providing lessons learned. However, while the experience is generally applicable to East Central European countries, differences in boiler design, operation and coal characteristics also need to be considered. This paper begins with a comparison of the NO{sub x} regulations, identifies the key NO{sub x} control technologies and the worldwide experience with them, and discusses the achievable NO{sub x} reduction, O&M impacts, and retrofit costs for each technology. Emphasis is placed on retrofit applications for existing boilers, because new coal-fired power plants are not expected to be built for the next 5-10 years. This paper also focuses on technologies with relatively low cost and operational simplicity: combustion system tuning/optimization. low-NO{sub x} burners (LNB), overfire air (OFA), selective non-catalytic reduction (SNCR), and reburning.

  14. Perceived challenges to public health in Central and Eastern Europe: a qualitative analysis

    PubMed Central

    2012-01-01

    Background There is a major gradient in burden of disease between Central and Eastern Europe compared to Western Europe. Many of the underlying causes and risk factors are amenable to public health interventions. The purpose of the study was to explore perceptions of public health experts from Central and Eastern European countries on public health challenges in their countries. Methods We invited 179 public health experts from Central and Eastern European countries to a 2-day workshop in Berlin, Germany. A total of 25 public health experts from 14 countries participated in May 2008. The workshop was structured into 8 sessions of 1.5 hours each, with the topic areas covering coronary heart disease, stroke, prevention, obesity, alcohol, tobacco, tuberculosis, and HIV/AIDS. The workshop was recorded and the proceedings transcribed verbatim. The transcripts were entered into atlas.ti for content analysis and coded according to the session headings. After analysis of the content of each session discussion, a re-coding of the discussions took place based on the themes that emerged from the analysis. Results Themes discussed recurred across disease entities and sessions. Major themes were the relationship between clinical medicine and public health, the need for public health funding, and the problems of proving the effectiveness of disease prevention. Areas for action identified included the need to engage with the public, to create a better scientific basis for public health interventions, to identify “best practices” of disease prevention, and to implement registries/surveillance instruments. The need for improved data collection was seen throughout all areas discussed, as was the need to harmonize data across countries. Conclusions To reduce the burden of disease across Europe, closer collaboration of countries across Europe seems important in order to learn from each other. A more credible scientific basis for effective public health interventions is urgently

    The poor health and psychological well-being of people in the former socialist states of Centeral-Eastern Europe are of serious concern and may be related to low perceived control. We compared depressive symptoms, life satisfaction, and self-rated health in 3,571 male and female university students from 5 Western European countries and 4,793 students from 5 Central-Eastern European countries. Depression scores (short Beck Depression Inventory; Beck & Beck, 1972) were higher in Central-Eastern than Western European samples. The prevalence of low life satisfaction was also greater in Central-Eastern Europeans, but ratings of self-rated health did not differ. Ratings of perceived control were diminished, but sense of mastery and internal health locus of control were higher in Central-Eastern Europe. Depression and low life satisfaction were associated with low perceived control and mastery and with strong beliefs in the influence of chance over health. However, taking these factors into account did not explain the East-West difference in depressive symptoms and low life satisfaction.

    The main objective of the paper concerns the determination of the annual and multi-annual variability of air flow over East-Central Europe in the period 1871-2010. Daily mean sea-level pressure and values of physical quantities provided the basis for distinguishing 27 circulation types, i.e., eight directional cyclonic, transitional, and anticyclonic types, and one non-directional cyclonic, anticyclonic, and an undefined type. Over the area of East-Central Europe, the highest frequency is recorded for air flow from the western sector, with a maximum in the period from December to January. In spring, a higher than average frequency of cyclonic and easterly circulation is observed, and in summer—anticyclonic and northerly. Increased zonal circulation was recorded in the years 1910-1930, and particularly after 1970, and eastern at the end of the nineteenth century and in the 1930s and 1940s. An increase in the frequency of days with non-directional anticyclonic type and westerly air flow, and a simultaneous decrease in frequency of days with south-easterly and easterly circulation were observed throughout the study period. Among the three classes of circulation types, the highest persistence (particularly in winter) was recorded for anticyclonic types, i.e., when the high pressure system occurred over the Scandinavian Peninsula or East Europe.

    With the rapid growth in the number of seismic stations globally, automated analysis routines are inevitable to extract seismic observables from these large data volumes. For surface wave tomography, phase velocity dispersion curves of fundamental mode surface waves yield information on the isotropic as well as anisotropic structure of the crust and upper mantle. We have new developed an algorithm that enables automated, accurate measurement of inter-station phase velocity dispersion curves through cross correlation of vertical (Rayleigh wave) and transverse component (Love wave) seismograms. After testing various parameters for automation of the procedure we find that the automated selection of segments of a given phase-velocity curve requires three parameters only, namely (1) difference of the measured phase velocity curve from a background model, (2) a smoothness constraint and (3) a length criterion. Furthermore, before averaging phase velocities for one path outliers are rejected. We performed rigorous tests to optimize the selection parameters. Interestingly, rough perturbations in the phase velocity curves do not bias the average phase velocities towards larger values. This indicates a rather random perturbation of the phase velocities by noise and complicated non-plane wave propagation. We successfully applied the method to more than one hundred thousand inter station paths in central and northern Europe, involving more than one million cross correlations on 20 years of data from permanent networks. After inversion of the fundamental mode phase velocity dispersion curves for both Rayleigh and Love waves, we obtain high resolution anisotropic phase velocity maps for periods between 10 and 250 seconds with a lateral resolution between about 50 to 200 kilometers in Central Europe. At shorter periods the North-German and Polish sedimentary basins are clearly imaged. At lower crustal depth the Alpine crustal root is characterized by low velocities. At longer

    Background Coppicing was one of the most important forest management systems in Europe documented in prehistory as well as in the Middle Ages. However, coppicing was gradually abandoned by the mid-20th century, which has altered the ecosystem structure, diversity and function of coppice woods. Methodology/Principal Findings Our aim was to disentangle factors shaping the historical growth dynamics of oak standards (i.e. mature trees growing through several coppice cycles) in a former coppice-with-standards in Central Europe. Specifically, we tried to detect historical coppicing events from tree-rings of oak standards, to link coppicing events with the recruitment of mature oaks, and to determine the effects of neighbouring trees on the stem increment of oak standards. Large peaks in radial growth found for the periods 1895–1899 and 1935–1939 matched with historical records of coppice harvests. After coppicing, the number of newly recruited oak standards markedly grew in comparison with the preceding or following periods. The last significant recruitment of oak standards was after the 1930s following the last regular coppicing event. The diameter increment of oak standards from 1953 to 2003 was negatively correlated with competition indices, suggesting that neighbouring trees (mainly resprouting coppiced Tilia platyphyllos) partly suppressed the growth of oak standards. Our results showed that improved light conditions following historical coppicing events caused significant increase in pulses of radial growth and most probably maintained oak recruitment. Conclusions/Significance Our historical perspective carries important implications for oak management in Central Europe and elsewhere. Relatively intense cutting creating open canopy woodlands, either as in the coppicing system or in the form of selective cutting, is needed to achieve significant radial growth in mature oaks. It is also critical for the successful regeneration and long-term maintenance of oak

    The CONTRACE project investigates the uplift of pollution in frontal systems (warm conveyor belts) over North America and the transport of these air masses to Europe. The first airborne field experiment was carried out from Southern Germany in fall 2001. The DLR research aircraft Falcon was equipped with a complex instrumentation to measure NO, NOy, CO, CO2, O3, J(NO2), acetone, SO2, ions, H2O2, formaldehyde, NMHC, J(O1D) and particles. An extensive set of chemical and meteorological forecast products, including trajectory calculations, was developed and used in combination with satellite images to plan the flights. A passive tracer for surface emissions (CO) was included in the forecast models to separate the regional and intercontinental transport of polluted air masses. For the first time it succeeded to guide the Falcon aircraft into pollution plumes transported all the way from North America (NA). On 22nd November a complex chemical weather situation was predicted for Central Europe with lifting of European emissions into the lower troposphere ahead of an approaching cold front and simultaneously, the advection of a pollution plume from Eastern NA in mid tropospheric layers. Similar CO mixing ratios were observed in both plumes making it difficult to distinguish the two plumes without additional trace gas information. The European pollution plume was characterized by large enhancements in the CO (150 ppbv) and NOy (6 ppbv) mixing ratios. The NOy/CO ratio was 0.135 (typical value for fresh emissions). In comparison the estimated NOy/CO ratio for the NA pollution plume was 0.010 which indicate a tracer age of 4 days. The observed CO and NOy mixing ratios in this plume were 160 ppbv and 1 ppbv. The two plumes were also characterized by very different O3/CO relationships. In the plume from NA a positive O3/CO slope was observed indicating photochemical ozone production (O3 mixing ratios up to 50 ppbv were observed). Most likely O3 was produced photochemically in

    2013-01-01

    Background Since the early 1990s former communist countries have been reforming their health care systems, emphasizing the key role of primary care and recognizing family medicine as a specialty and an academic discipline. This study assesses the level of academic development of the discipline characterised by education and research in central and eastern European (CEE) countries. Methods A key informants study, using a questionnaire developed on the basis of a systematic literature review and panel discussions, conducted in 11 central and eastern European countries and Russia. Results Family medicine in CEE countries is now formally recognized as a medical specialty and successfully introduced into medical training at undergraduate and postgraduate levels. Almost all universities have FM/GP departments, but only a few of them are led by general practitioners. The specialist training programmes in all countries except Russia fulfil the recommendations of the European Parliament. Structured support for research in FM/GP is not always available. However specific scientific organisations function in almost all countries except Russia. Scientific conferences are regularly organised in all the countries, but peer-reviewed journals are published in only half of them. Conclusions Family medicine has a relatively strong position in medical education in central and eastern Europe, but research in family practice is less developed. Although the position of the discipline at the universities is not very strong, most of the CEE countries can serve as an example of successful academic development for countries southern Europe, where family medicine is still not fully recognised.

    The occurrence of potential aflatoxin producing fungi was examined in various agricultural products and indoor air in Central European countries including Hungary, Serbia and Croatia. For species identification, both morphological and sequence based methods were applied. Aspergillus flavus was detected in several samples including maize, cheese, nuts, spices and indoor air, and several isolates were able to produce aflatoxins. Besides, three other species of Aspergillus section Flavi, A. nomius, A. pseudonomius and A. parasiticus were also isolated from cheese, maize and indoor air, respectively. This is the first report on the occurrence of A. nomius and A. pseudonomius in Central Europe. All A. nomius, A. pseudonomius and A. parasiticus isolates were able to produce aflatoxins B1, B2, G1 and G2. The A. nomius isolate came from cheese produced very high amounts of aflatoxins (above 1 mg ml⁻¹). All A. nomius, A. pseudonomius and A. parasiticus isolates produced much higher amounts of aflatoxin G1 then aflatoxin B1. Further studies are in progress to examine the occurrence of producers of these highly carcinogenic mycotoxins in agricultural products and indoor air in Central Europe.

    As result of the gradually increasing nanotechnology sector there is the necessity of a contemporary analysis of the present regulations used for nanomaterials, to outline the current situation of the nanotechnology sector, to promote international cooperation and research's coordination to overcome disciplinary boundaries, to fill the gap between more and less experienced regions and to turn investments in R&D in industrial innovations. The general objective of the Central Europe project NANOFORCE, which is developed by national and regional chemistry associations and R&D Centres of the Central Europe area, is to foster the innovative nanotechnology-sector networks across Central Europe regions by bringing together public and private organizations to carry out collaborative and interdisciplinary researches on nanomaterials (in the frame of REACH Regulation) and to turn the most promising laboratory results into innovative industrial applications. To build up a legal advisory board for chemical enterprises starting in nanotechnology, a state of the art report on existing safety procedures and nanotech related regulations was produced to give an overview on currently available regulations used by chemical industries and manufacturing companies within the European region to secure their products. The main emphasis was placed on REACH regulation to search for relevant sections concentrating on nanomaterials which are applicable for nanotechnology. In addition, all relevant directives and amendments of REACH were screened with regard to identify gaps where action is still needed and give possible recommendations for the European Commission. Beyond literature research a questionnaire for producers, users, researchers and financiers was developed with the goal to collect information about the nanotechnology sector in the CE region concerning development, financial status, and international cooperation within joint ventures, safety and nanotoxicology.

    2013-04-01

    The demand for skilful climate predictions on time-scales of several years to decades has increased in recent years, in particular for economic, societal and political terms. Within the BMBF MiKlip consortium, a decadal prediction system on the global to local scale is currently being developed. The subproject PRODEF is part of the MiKlip-Module C, which aims at the regionalisation of decadal predictability for Central and Western Europe. In PRODEF, a combined statistical-dynamical downscaling (SDD) and a probabilistic forecast tool are developed and applied to the new Earth system model of the Max-Planck Institute Hamburg (MPI-ESM), which is part of the CMIP5 experiment. Focus is given on the decadal predictability of windstorms, related wind gusts as well as wind energy potentials. SDD combines the benefits of both high resolution dynamical downscaling and purely statistical downscaling of GCM output. Hence, the SDD approach is used to obtain a very large ensemble of highly resolved decadal forecasts. With respect to the focal points of PRODEF, a clustering of temporal evolving atmospheric fields, a circulation weather type (CWT) analysis, and a storm damage indices analysis is applied to the full ensemble of the decadal hindcast experiments of the MPI-ESM in its lower resolution (MPI-ESM-LR). The ensemble consists of up to ten realisations per yearly initialised decadal hindcast experiments for the period 1960-2010 (altogether 287 realisations). Representatives of CWTs / clusters and single storm episodes are dynamical downscaled with the regional climate model COSMO-CLM with a horizontal resolution of 0.22°. For each model grid point, the distributions of the local climate parameters (e.g. surface wind gusts) are determined for different periods (e.g. each decades) by recombining dynamical downscaled episodes weighted with the respective weather type frequencies. The applicability of the SDD approach is illustrated with examples of decadal forecasts of the MPI

    Based on stable isotope analyses of worldwide reference curves from deep sea, ice core and speleothem records, it has long been apparent that duration, intensity and climatic conditions of different interglacial periods were significantly diverse. As a consequence of negligible fresh, detrital material admixture during interglacials, the soil formation intensity and maturity of various kinds of past soils have been holding vital information on the environmental conditions at the time the soils formed. This, in turn, means that several physical and chemical properties of soils allow us to reconstruct past climatic regimes. Loess-paleosol sequences in Hungary (Central Europe) provide insight into the cyclic nature of glacial-interglacial variations of the last 1 million years. The paleosoils have been recognized as the product of warmer and moister interglacials, when the (glacial) loess material was altered by chemical weathering and pedogenic processes. 12 pedogene units from MIS-19 to MIS-5 strata were analysed in the course of this study, with a special attention to MIS-11 and MIS-19 periods, because of these can be regarded as analogues of the Holocene interglacial (due to the similarities in obliquity and eccentricity). Grain size, geochemical and (clay)mineralogical studies were elaborated and were gathered from previously published papers to quantify past weathering intensity and paleoenvironmental conditions by geochemical climofunctions. The Upper and partly, the Middle Pleistocene loess deposits are intercalated by steppe, forest-steppe and brown forest soils, while the older pedogene horizons are different kinds; these are red, Mediterranean-type soils. The MIS-5 pedocomplex consist of three parts at several Hungarian sites, however the pedogene units cannot be correlated unequivocally with the three MIS-5 warmer substages, due to the scarce absolute age data. The MIS-7 and MIS-9 stages are represented by three forest steppe soils. The MIS-11 pedocomplex

    The area defined as the N — S transect of Central Europe encompasses Slovenia, Croatia, Hungary, southern Slovakia, northern Austria, Moravia and southern Poland. Physical and biological environmental analysis have been undertaken for the Gravettian period of the last glacial, between 31 and 22 ka cal BP. Mammal faunas have been recorded from different provinces, which have climatic differences. These climatic differences are reflected in the sediments, the plant cover and the fauna. Over the course of several warm and cold events from 31-22 ka the biodiversity of the individual provinces has remained roughly the same, but important quantitative changes have occurred in the individual faunas.

    This article argues that the health-related Millennium Development Goals do not appropriately address the challenges faced by the countries of Eastern Europe and Central Asia. By ignoring adult mortality, their achievement would result in relatively small gains in life expectancy. To achieve greater impact, policies in this region must supplement the classical Millennium Development Goals with indicators of adult health, in particular cardiovascular diseases and external causes of death. In addition, countries, with support from the international community, must improve the quality of vital registration data to enable more accurate estimation of the disease burden.

    Regional climate predictions on timescales from one year to one decade are gaining importance since this time frame falls within the planning horizon of politics, economy, and society. In this context, decadal predictions are of particular interest for the development of renewable energies such as wind energy. The present study examines the decadal predictability of regional scale wind speed and wind energy potentials in the framework of the MiKlip consortium ("Mittelfristige Klimaprognosen"; www.fona-miklip.de). This consortium aims to develop a model system based on the Max-Planck-Institute Earth System Model (MPI-ESM) that can provide skilful decadal predictions on regional and global scales. Three generations of the decadal prediction system, which differ primarily in their ocean initialisation, are analysed here. Ensembles of uninitialised historical and yearly initialised hindcast experiments are used to assess different skill scores for 10m wind speeds and wind energy output (Eout) over Central Europe, with special focus given to Germany. With this aim, a statistical-dynamical downscaling (SDD) approach is used for the regionalisation of the global datasets. Its added value is evaluated by comparison of skill scores for MPI-ESM large-scale wind speeds and SDD simulated regional wind speeds. All three MPI-ESM ensemble generations show some forecast skill for annual mean wind speed and Eout over Central Europe on yearly and multi-yearly time scales. The forecast skill is mostly limited to the first years after initialisation. Differences between the three ensemble generations are generally small. The regionalisation preserves and sometimes increases the forecast skill of the global runs but results depend on lead time and ensemble generation. Moreover, regionalisation often improves the ensemble spread. Seasonal Eout skills are generally lower than for annual means. Skill scores are lowest during summer, and persist longest in autumn.

    Foliar damage to trees by air pollution in Central and Eastern Europe has been a major scientific and political issue. Emissions of toxic gases such as sulfur dioxide and nitrogen oxides can have wide-ranging effects on local and regional vegetation that can be compounded by other environmental stresses to plant growth. Since uptake and physiological effects of these gases on tree leaves we largely, mediated by stomata, surrogate methods for estimating pollutant conductances into leaves and forest canopies may lead to risk assessments for major vegetation types that can then be used in regional planning. Management options to ameliorate or mitigate air pollutant damage to forests and losses in productivity are likely to be more difficult to widely implement than on-the-stack emissions abatement. Informed management and policy decisions regarding Central and Eastern European forests are dependent on the development of quantitative tools and models for risk assessment of the effects of atmospheric pollutants on ecosystem health and productivity.

    Behçet's disease (BD) is a multiorgan inflammatory disease of complex and not entirely elucidated etiology, which was originally diagnosed in patients with aphthous stomatitis, genital ulcerations and ocular manifestations. The entity is endemic in countries of Eastern and Central Asia, especially Turkey and Iran, but rarely seen in Central Europe. As there are no specific diagnostic laboratory tests or histopathologic findings which confirm the preliminary diagnosis, the final diagnosis should be based on clinical criteria. Frequently a definitive diagnosis is established within several years or months after the first manifestations appear. The increased number of cases, recently described worldwide also in the Polish population, indicates that the disease could spread out of endemic areas. The aim of this manuscript is to present the clinical picture, diagnosis criteria and therapeutic approaches of this “international disease” which currently is observed not only in emigrants from Asia but also in native Polish citizens.

    The ever expanding Central and Eastern European Proteomic Conference (CEEPC) hosted its 8th annual meeting in Vienna, Austria, in July 2014 with resounding success, highlights of which are shared in this report. Tremendous progress in proteomics over the past decade in Central and Eastern Europe continues to rapidly accelerate due to networking across borders as well as access to sophisticated technologies. As the popularity of targeted proteomics in pathogenesis grows to unravel the complexities, so does the use of advanced analytical instrumentation. In addition, development of more sensitive research methodologies and a massive integration of technologies now give optimism to gain better understanding of the structure, functions and isoforms of various proteins as well as their complex interactions in biological systems. This, together with the confidence to qualitatively and/or quantitatively interrogate proteins of interest has led to promising developments for the identification of potential new drug targets for the treatment of various diseases.

    The giant deer Megaloceros giganteus is among the most fascinating Late Pleistocene Eurasian megafauna that became extinct at the end of the last ice age. Important questions persist regarding its phylogenetic relationship to contemporary taxa and the reasons for its extinction. We analyzed two large ancient cervid bone fragments recovered from cave sites in the Swabian Jura (Baden-Württemberg, Germany) dated to 12,000 years ago. Using hybridization capture in combination with next generation sequencing, we were able to reconstruct nearly complete mitochondrial genomes from both specimens. Both mtDNAs cluster phylogenetically with fallow deer and show high similarity to previously studied partial Megaloceros giganteus DNA from Kamyshlov in western Siberia and Killavullen in Ireland. The unexpected presence of Megaloceros giganteus in Southern Germany after the Ice Age suggests a later survival in Central Europe than previously proposed. The complete mtDNAs provide strong phylogenetic support for a Dama-Megaloceros clade. Furthermore, isotope analyses support an increasing competition between giant deer, red deer, and reindeer after the Last Glacial Maximum, which might have contributed to the extinction of Megaloceros in Central Europe.

    This study tests the hypothesis that Danish agricultural areas are the main source to airborne Alternaria spores in Copenhagen, Denmark. We suggest that the source to the overall load is mainly local, but with intermittent Long Distance Transport (LDT) from more remote agricultural areas. This hypothesis is supported by investigating a 10 yr bi-hourly record of Alternaria spores in the air from Copenhagen. This record shows 232 clinically relevant episodes with a distinct daily profile. The data analysis also revealed potential LDT episodes almost every year. A source map and analysis of atmospheric transport suggest that LDT always originates from the main agricultural areas in Central Europe. A dedicated emission study in cereal crops under harvest during 2010 also supports our hypothesis. The emission study showed that although the fields had been treated against fungal infections, harvesting still produced large amounts of airborne fungal spores. It is likely that such harvesting periods can cause clinically relevant levels of fungal spores in the atmosphere. Our findings suggest that crop harvest in Central Europe causes episodes of high airborne Alternaria spore concentrations in Copenhagen as well as other urban areas in this region. It is likely that such episodes could be simulated using atmospheric transport models.

    Across much of central Europe, the Linearbandkeramik (LBK) represents the first Neolithic communities. Arising in Transdanubia around 5500 cal. BC the LBK spread west to the Rhine within two to three hundred years, carrying elements of a mixed agricultural economy and a relatively homogeneous material culture. Colonisation of new regions during this progress would have required economic adaptations to varied ecological conditions within the landscape. This paper investigates whether such adaptation at a local scale affected health patterns and altered the dietary habits of populations that otherwise shared a common cultural and biological origin. Analysis of non-specific stress (linear enamel hypoplasia, porotic hyperostosis, cribra orbitalia) within five LBK populations from across central Europe in conjunction with published carbon and nitrogen stable isotope data from each site revealed a high prevalence of porotic hyperostosis and cribra orbitalia in western populations that was associated with a lower animal protein intake. Hypoplastic enamel was more frequently observed in eastern populations however, and may reflect geographic differences in childhood morbidity and mortality as a result of variation in social practices relating to weaning. Local socio-economic adaptations within the LBK were therefore an important factor in the exposure of populations to non-specific stress. PMID:27385276

    The vairone Leuciscus souffia is a cyprinid fish that inhabits river systems in and around the Alps. The complete mitochondrial DNA control region (945 bp) was sequenced in 295 vairone from 22 populations in Central Europe. A total of 51 haplotypes were identified with a maximum pairwise distance between haplotypes of 5.6%. Phylogenetic analyses revealed two major clades in L. souffia, an 'Italian' clade, and an 'Alpine' clade. Two hybrid zones exist, in the Mediterranean Alps and in the Soca basin. The position of the sister species of L. souffia, L. turskyi, to the 'Alpine' and the 'Italian' clade could not be resolved unambiguously. However, a linearized tree analysis indicated that L. turskyi represents a third lineage, that originated at the same time as the 'Alpine' and the 'Italian' clades of L. souffia. In the 'Alpine' clade two groups were resolved, a subclade with haplotypes from the Rhône and Var basins and a cluster with haplotypes from the Danube and Rhine systems. Our data suggest a long history of the vairone in Central Europe, predating Pleistocene glacial cycles. Two main refugia during glaciations must have existed, one in Italy and another one most probably in the Danube system. However, age estimates based on molecular clock calibrations suggest the survival of 'Alpine' haplotypes in several drainages during the last glaciation cycles. The Rhine system was only recently colonized.

    This article discusses the applicability of the new institutionalism to the politics of health care reform in postcommunist Central Europe. The transition to a market economy and democracy after the fall of communism has apparently strengthened the institutional approaches. The differences in performance of transition economies have been critical to the growing understanding of the importance of institutions that foster democracy, provide security of property rights, help enforce contracts, and stimulate entrepreneurship. From a theoretical perspective, however, applying the new institutionalist approaches has been problematic. The transitional health care reform exposes very well some inherent weaknesses of existing analytic frameworks for explaining the nature and mechanisms of institutional change. The postcommunist era in Central Europe has been marked by spectacular and unprecedented radical changes, in which the capitalist system was rebuilt in a short span of time and the institutions of democracy became consolidated. Broad changes to welfare state programs were instituted as well. However, the actual results of the reform processes represent a mix of change and continuity, which is a challenge for the theories of institutional change.

    Background and Aims Plants endemic to areas covered by ice sheets during the last glaciation represent paradigmatic examples of rapid speciation in changing environments, yet very few systems outside the harsh arctic zone have been comprehensively investigated so far. The Galium pusillum aggregate (Rubiaceae) is a challenging species complex that exhibits a marked differentiation in boreal parts of Northern Europe. As a first step towards understanding its evolutionary history in deglaciated regions, this study assesses cytological variation and ecological preferences of the northern endemics and compares the results with corresponding data for species occurring in neighbouring unglaciated parts of Central and Western Europe. Methods DNA flow cytometry was used together with confirmatory chromosome counts to determine ploidy levels and relative genome sizes in 1158 individuals from 181 populations. A formalized analysis of habitat preferences was applied to explore niche differentiation among species and ploidy levels. Key Results The G. pusillum complex evolved at diploid and tetraploid levels in Northern Europe, in contrast to the high-polyploid evolution of most other northern endemics. A high level of eco-geographic segregation was observed between different species (particularly along gradients of soil pH and competition) which is unusual for plants in deglaciated areas and most probably contributes to maintaining species integrity. Relative monoploid DNA contents of the species from previously glaciated regions were significantly lower than those of their counterparts from mostly unglaciated Central Europe, suggesting independent evolutionary histories. Conclusions The aggregate of G. pusillum in Northern Europe represents an exceptional case with a geographically vicariant and ecologically distinct diploid/tetraploid species endemic to formerly glaciated areas. The high level of interspecific differentiation substantially widens our perception of the

    Background and Aims A detailed knowledge of cytotype distribution can provide important insights into the evolutionary history of polyploid systems. This study aims to explore the spatial distribution of different cytotypes in Pilosella echioides at various spatial scales (from the whole distributional range to the population level) and to outline possible evolutionary scenarios for the observed geographic pattern. Methods DNA-ploidy levels were estimated using DAPI flow cytometry in 4410 individuals of P. echioides from 46 populations spread over the entire distribution range in central Europe. Special attention was paid to the cytotype structure in the most ploidy-diverse population in south-west Moravia. Key Results Five different cytotypes (2x, 3x, 4x, 5x and 6x) were found, the last being recorded for the first time. Although ploidy-uniform (di- or tetraploid) sites clearly prevailed, nearly one-quarter of the populations investigated harboured more (up to all five) cytotypes. Whereas penta- and hexaploids constituted only a minority of the samples, a striking predominance of the triploid cytotype was observed in several populations. Conclusions The representative sampling confirmed previous data on cytotype distribution, i.e. the spatial aggregation of mixed-ploidy populations in south-west Moravia and Lower Austria and the predominance of ploidy-uniform populations in other parts of the area investigated. Recurrent origin of polyploids from diploid progenitors via unreduced gametes and their successful establishment are considered the key factors promoting intrapopulational ploidy mixture (‘primary hybrid zones’). As an alternative to the generally accepted theory of cytotype co-existence based on the development of different means of inter-ploidy reproductive isolation, it is suggested that a long-term ploidy mixture can also be maintained in free-mating populations provided that the polyploids originate with a sufficient frequency.

    When aiming higher resolution in dynamical downscaling, which is common trend in CORDEX activities, the effects of land use and land use changes are playing increasing role. This is especially true for the urban areas, which in high resolution can occupy significant part of a single gridbox, if not being even bigger in case of big cities or megacities. Moreover, the role of cities will increase in future, as the population within the urban areas is growing faster, with the estimate for Europe of about 84% living in cities. For the purpose of qualifying and quantifying the impact of cities and in general the urban surfaces on climate, the surface parameterization in regional climate model RegCM4 has been coupled with the Single Layer Urban Canopy Model (SLUCM), which can be used both in dynamic scale within BATS scheme and in a more detailed SUBBATS scale to treat the surface on a higher resolution subgrid. A set of experiments was performed over the period of 2005-2009 over central Europe, either without considering urban surfaces and with the SLUCM treatment. Results show a statistically significant impact of urbanized surfaces on temperature (up to 1.5 K increase in summer), on the boundary layer height (ZPBL, increases up to 50 m). Additionally, the version of land-surface scheme using CLM is tested and effect of the urban environment, which is included in the CLM scheme, will be assessed. Both versions will be compared and validated using EOBS data.

    Leprosy was rare in Europe during the Roman period, yet its prevalence increased dramatically in medieval times. We examined human remains, with paleopathological lesions indicative of leprosy, dated to the 6th-11th century AD, from Central and Eastern Europe and Byzantine Anatolia. Analysis of ancient DNA and bacterial cell wall lipid biomarkers revealed Mycobacterium leprae in skeletal remains from 6th-8th century Northern Italy, 7th-11th century Hungary, 8th-9th century Austria, the Slavic Greater Moravian Empire of the 9th-10th century and 8th-10th century Byzantine samples from Northern Anatolia. These data were analyzed alongside findings published by others. M. leprae is an obligate human pathogen that has undergone an evolutionary bottleneck followed by clonal expansion. Therefore M. leprae genotypes and sub-genotypes give information about the human populations they have infected and their migration. Although data are limited, genotyping demonstrates that historical M. leprae from Byzantine Anatolia, Eastern and Central Europe resembles modern strains in Asia Minor rather than the recently characterized historical strains from North West Europe. The westward migration of peoples from Central Asia in the first millennium may have introduced different M. leprae strains into medieval Europe and certainly would have facilitated the spread of any existing leprosy. The subsequent decline of M. leprae in Europe may be due to increased host resistance. However, molecular evidence of historical leprosy and tuberculosis co-infections suggests that death from tuberculosis in leprosy patients was also a factor.

    The EU-project CECILIA (Central and Eastern Europe Climate Change Impact and VulnerabiLIty Assessment) aims at delivering a climate change impacts and vulnerability assessment in targeted areas of Central and Eastern Europe. This region appears particularly vulnerable with regard to future changes in extremes (Christensen and Christensen 2003, Schär et al. 2004), likely due to regional specificities such as highly varying topography and continentality, and due to changes in soil moisture content (Seneviratne et al. 2006). In the project, emphasis is given to applications of regional climate modeling studies at a resolution of 10 km for local impact studies in key sectors of the region. The project includes the analysis of extreme weather events in present day and future climate in the target region. For this purpose, an extensive list of precipitation and temperature indices was defined. Observational data used for the indices calculation comes from the European Climate Assessment & Dataset project (ECA&D, Klein Tank et al. 2002), from the ENSEMBLES gridded observations (E-Obs, Haylock et al. 2008), and from station data of the local partners in Central and Eastern Europe. Moreover, the same indices were calculated consistently for a selection of pre-existing RCM datasets (PRUDENCE, ENSEMBLES), and for the CECILIA driving models. Later on, the 10 km high-resolution climate simulations from CECILIA will be included in the analysis. Here we focus on the analysis of a selection of temperature indices, and on the validation of the model-derived indices with the observations. Generally, the spatial agreement between the models and the observations is very good for mean, maximum and minimum temperature (both in terms of the spatial variability and the spatial correlation). The spread between the models is larger for the daily temperature range, with most models showing larger spatial variability compared to the observations. When it comes to heat and cold wave indices

    Since 2009 the Centre of Applied Geomatics of the Military University of Technology acts as one of the 18 Local Analysis Centers within EPN (EUREF Permanent Network). The duty of the LAC is to process a subnetwork of EPN stations and deliver weekly free network solutions to the Combination Centre as well as make research aimed at interpretation of obtained sites' coordinates. We have used satellite data from more than 300 permanent sites located in Europe, incorporated to EPN and supplemented by the sites operated within Polish GBAS (Ground-Based Augmentation System) called ASG-EUPOS for investigation of the regional geokinematic effects. These observations were processed by means of combining the normal equations using BERNESE 5.0 software. The velocities of permanent sites were determined from time series (geocentric coordinates) in two ways: using robust estimation using M-estimators and with CATREF software with no significant differences obtained. The several methods of interpolation of velocities into regular grid were tested. The research on regional kinematics was done by scientific description of continuous velocity model in comparison with different discontinuous models with geological structure taken into consideration. Finally the strain rates of Central Europe were elaborated using GRID_STRAIN software and compared to the previously determined empirical models.

    Rumex confertus is a biennial species native to Eastern Europe and Asia, where it thrives on meadow-steppes and glades in forest-steppe. This species has increased its range rapidly within central Europe, yet its biology is not well understood, which has led to poorly timed management. Effects of temperature, light, sodium chloride (NaCl), hydrogen ion concentration (pH), potassium nitrate (KNO3), and polyethylene glycol 6000 on seed germination were examined. Seedling emergence was examined for seeds sown at different depths in sand-filled pots. Seeds of R. confertus were nondormant at maturity. The germination percentage and rate of germination were significantly higher in light than in darkness. Secondary dormancy was induced in these seeds by 12 weeks of dark incubation at 4°C. The seeds of R. confertus undergo a seasonal dormancy cycle with deep dormancy in winter and early spring and a low level of dormancy in early autumn. Germination decreased as soil salinity increased. NO3(-) increased the percentage and rate of germination in the studied species. Decrease in seedling emergence from the seeds buried at >0.5 cm may be due to deficiency of light. From our experiments, we conclude that the weed R. confertus normally becomes established in vegetation gaps or due to disturbance of the uppermost soil layer during the growing season through the germination of seeds originating from a long-lived seed bank.

    Publication ethics is an important aspect of both the research and publication enterprises. It is particularly important in the field of biomedical science because published data may directly affect human health. In this article, we examine publication ethics policies in biomedical journals published in Central and Eastern Europe. We were interested in possible differences between East European countries that are members of the European Union (Eastern EU) and South-East European countries (South-East Europe) that are not members of the European Union. The most common ethical issues addressed by all journals in the region were redundant publication, peer review process, and copyright or licensing details. Image manipulation, editors' conflicts of interest and registration of clinical trials were the least common ethical policies. Three aspects were significantly more common in journals published outside the EU: statements on the endorsement of international editorial standards, contributorship policy, and image manipulation. On the other hand, copyright or licensing information were more prevalent in journals published in the Eastern EU. The existence of significant differences among biomedical journals' ethical policies calls for further research and active measures to harmonize policies across journals.

    In Europe polecat populations are declining for unknown reasons during the last decades. Data on the river otter, another mustelid predator, indicate that PCB levels are high enough in some populations to interfere with the reproduction of this aquatic species. Since the diet of the polecats consists to a large amount of aquatic prey (amphibians) it appears reasonable to assume that PCBs ingested with the prey are a factor in the decline of polecats. To test this assumption PCB residues in amphibians and in adipose tissue and liver of polecats from Southwest Germany were quantified and the results were compared with literature data on the reproductive toxicity of PCBs in feral mink. According to the current data total PCB levels in polecats (adipose tissue, mean 1244 ng/g lipids; liver, mean 1677 ng/g lipids) and their prey (frogs, mean 9279 ng/kg fresh weight; toads, 4948 ng/kg fresh weight) are comparatively low. Using the toxic equivalent approach, it was calculated that polecats could feed exclusively on amphibians without consuming a harmful amount of PCBs. Therefore, PCBs cannot be an agent currently affecting polecat populations in Central Europe. Other environmental factors like habitat destruction or road accidents are more likely to have a negative impact on polecat populations. PMID:11161692

    In 2012 the Chinese navigation satellite system called BeiDou System (BDS) has reached the regional operational capabilities over the area of East Asia. Currently the BDS system consists of 5 medium orbit satellites MEO, 6 geosynchronous satellites IGSO and 5 geostationary satellites GEO and provides regional coverage by its navigation signals. Also in Europe BDS satellites can be used to determine position. In 2015 the third phase of BSD system development has started, aimed at providing global coverage and compatibility with other GNSS systems. As a result, BDS will broadcast signals at the same frequency as GPS L1 and L5 and Galileo E1, E5a and E5b. In the presented research we carried out relative positioning using the MAFA method. This was the first time when this method was applied to process BDS signals. The results show that it is possible to obtain precise position in central Europe using BDS signals only. However, with its current constellation, this is not possible 24/7, but in periodic time windows.

In Central Europe, only Seewis virus, associated with the Eurasian common shrew (Sorex araneus), has been recognized until now. In the present report, tissue samples from shrews belonging to Crocidurinae and Soricinae subfamilies, trapped in Czech Republic, Germany, and Slovakia, were screened for the presence of novel hantaviruses. Three new hantavirus partial L-segment sequences were obtained from pygmy shrews (Sorex minutus) trapped in Czech Republic and Germany. Complete nucleocapsid protein- and glycoprotein precursor-coding S- and M-segment sequences were then determined for the newly recognized hantavirus strains, CZ/Beskydy/412/2010/Sm, CZ/Drahany/420/2010/Sm, and DE/Dürrbach/1912/2009/Sm. Phylogenetic analyses showed that they represent strains of Asikkala virus (ASIV), a novel hantavirus also found in pygmy shrews from Finland. Our study reveals a broad geographic distribution of ASIV across Europe and indicates pygmy shrew as the primary reservoir host. Future studies will have to determine the pathogenic relevance of ASIV.

    Rumex confertus is a biennial species native to Eastern Europe and Asia, where it thrives on meadow-steppes and glades in forest-steppe. This species has increased its range rapidly within central Europe, yet its biology is not well understood, which has led to poorly timed management. Effects of temperature, light, sodium chloride (NaCl), hydrogen ion concentration (pH), potassium nitrate (KNO3), and polyethylene glycol 6000 on seed germination were examined. Seedling emergence was examined for seeds sown at different depths in sand-filled pots. Seeds of R. confertus were nondormant at maturity. The germination percentage and rate of germination were significantly higher in light than in darkness. Secondary dormancy was induced in these seeds by 12 weeks of dark incubation at 4°C. The seeds of R. confertus undergo a seasonal dormancy cycle with deep dormancy in winter and early spring and a low level of dormancy in early autumn. Germination decreased as soil salinity increased. NO3(-) increased the percentage and rate of germination in the studied species. Decrease in seedling emergence from the seeds buried at >0.5 cm may be due to deficiency of light. From our experiments, we conclude that the weed R. confertus normally becomes established in vegetation gaps or due to disturbance of the uppermost soil layer during the growing season through the germination of seeds originating from a long-lived seed bank.

    Among the various “natural laboratories” of high natural or technical enhanced natural radiation environments in the world such as Kerala (India), Brazil, Ramsar (Iran), etc., the areas in and around the Central European Ore Mountains (Erzgebirge) in the southern parts of former East Germany, but also including parts of Thuringia, northern Bohemia (now Czech Republic), and northeastern Bavaria, are still relatively little known internationally. Although this area played a central role in the history of radioactivity and radiation effects on humans over centuries, most of the valuable earlier results have not been published in English or quotable according to the current rules in the scientific literature and therefore are not generally known internationally. During the years 1945 to 1989, this area was one of the world’s most important uranium mining areas, providing the former Soviet Union with 300,000 tons of uranium for its military programs. Most data related to health effects of radon and other carcinogenic agents on miners and residents became available only during the years after German reunification. Many of the studies are still unpublished, or more or less internal reports. By now, substantial studies have been performed on the previously unavailable data about the miners and the population, providing valuable insights that are, to a large degree, in disagreement with the opinion of various international bodies assuming an increase of lung cancer risk in the order of 10% for each 100 Bq/m3 (or doubling for 1000 Bq/m3), even for small residential radon concentrations. At the same time, other studies focusing on never-smokers show little or no effects of residential radon exposures. Experiments in medical clinics using radon on a large scale as a therapeutic against various rheumatic and arthritic disease demonstrated in randomized double-blind studies the effectiveness of such treatments. The main purpose of this review is to critically examine

    Preventive measures in Central Europe were successful in suppressing both occupational and environmental lead exposure so that they did not constitute a severe public health problem. However, rare lead intoxications still appear. We report on lead intoxication in four family members where the source was removed lead ceiling paint. The symptoms of the lead intoxication started several weeks after removal and the inhalational exposure to the minimum dust residues lasted for more than three months before the poisoning was diagnosed. Father developed anaemia and saturnine colics. He and his two daughters received antidotal treatment which had to be repeated in the children. Finally, all recovered completely.Lead intoxication may be easily overlooked due to the unspecific symptoms. It is necessary to think of this rare poisoning which may be caused by old paints, historical ceramics and lead shots, in addition to commercial products imported from abroad. PMID:27434242

    Heating is a vital energy service in Central and Eastern Europe, but the current delivery mechanisms are riddled with problems. District heating (DH) in its present technical form and with the present management structures is an inefficient system which produces expensive heat. Customers cannot control it and react to overheating by opening windows, even in winter. DH facilities together with other forms of individual heating are responsible for air pollution, causing severe impacts on the health of urban residents. The issues relating to DH are discussed, the first World Bank activities and experiences with projects in Poland are analyzed, and the cornerstones of a strategy to support future World Bank financing and the development of sound heating policies in CEE are presented.

This development--including the foundation or reforms of medical education--was highly influenced by the ideas of the enlightened absolutism and by other international trends of the age as well. The detailed analysis of the factors shaping the history of public health in the three rather different countries shows an interesing parallelism regarding main issues. While re-organization of public health in all these countries was initiated and directed by the government and shaped according to western models, it was strongly influenced by local possibilities, culture and history.

    The changes in Central and Eastern Europe caused by upheavals at the beginning of the 1990s had great impact on the formation and implementation of educational policies. A comparison of patterns in Russia, Poland, Hungary and the Czech Republic shows common features which were rooted in the collapse of the communist system. At the same time these transformation processes were marked by considerable diversity. To elucidate these commonalities and differences, the following problem areas are examined: (a) decentralisation of responsibilities; (b) financing and privatisation; (c) structural reforms; (d) curricular reforms; and (e) evaluation, assessment and examinations. These developments are considered in the light of various theories about how periods of social transformation unfold. The article helps to throw light on the differences between the countries of the region in terms of how the educational changes were perceived and carried out.

  6. Thunderstorm occurrence and characteristics in Central Europe under different synoptic conditions

    2015-05-01

    The occurrence and characteristics of thunderstorms in Central Europe are examined in relation to the predominant synoptic conditions as derived from an automatic classification of synoptic patterns. Lightning strokes measured by a lightning detection network, human thunderstorm observations at weather stations and convective cells derived from radar reflectivity are used. The analysis reveals conditions favourable for thunderstorm development and highlights regions affected under different flow regimes. Additionally, the cell-based analysis shows that different synoptic conditions are typically associated with specific cell characteristics, such as the direction and speed of movement or cell sizes and severity. These relationships can be explained meaningfully via a description of the synoptic-meteorological characteristics of each of the standard weather patterns. As such these results may support a better understanding of thunderstorm formation as well as improve forecasters' situational awareness.

  7. Types of geographical distribution of leaf beetles (Chrysomelidae) in Central Europe *

    Abstract A comparison of the geographical distribution patterns of 647 species of Chrysomelidae in Central Europe revealed 13 types of distribution: (1) widely distributed, (2) southern, (3) southeastern, (4) southwestern, (5) northern, (6) eastern, (7) south east quarter, (8) south west quarter, (9) fragmented, (10) montane, (11) subalpine & alpine, (12) scattered, (13) unusual, and irregular patterns produced by insufficient data. Some of these distributions are trivial (e. g. northern, eastern, etc., alpine) but others are surprising. Some cannot be explained, e. g. the remarkable gaps in the distribution of Chrysolina limbata (Fabricius, 1775) and in Aphthona nonstriata (Goeze, 1777). Although our 63.000 records are necessarily tentative, we found that the distribution maps from these data reflect in many cases the common knowledge on the occurrence of leaf beetles in specific areas.

    The epidemiological trend of increasing HIV incidence rates due to sexual transmission in Central and Eastern Europe has been documented. The current review analyzed research articles that report on a wide spectrum of vulnerable populations from this world region. Studies of injection drug users, commercial sex workers, men who have sex with men, adolescents and young adults all reported inconsistent condom use. However, these patterns varied across populations and geographic areas. Populations in former Soviet countries—most affected by HIV—also often appeared to have lower condom use rates. Intensified, comprehensive, and locally-tailored measures to curb sexual HIV transmission are urgently needed. Social development programs need to incorporate HIV prevention. PMID:22348631

    In the study, we screened a total of 399 adult sheep keds (Melophagus ovinus) for the presence of RNA and DNA specific for arboviral, bacterial, and protozoan vector-borne pathogens. All investigated keds were negative for flaviviruses, phleboviruses, bunyaviruses, Borrelia burgdorferi, Rickettsia spp., Anaplasma phagocytophilum, "Candidatus Neoehrlichia mikurensis," and Babesia spp. All ked pools were positive for Bartonella DNA. The sequencing of the amplified fragments of the gltA and 16S-23S rRNA demonstrated a 100 % homology with Bartonella melophagi previously isolated from a sheep ked and from human blood in the USA. The identification of B. melophagi in sheep keds in Central Europe highlights needs extending a list of hematophagous arthropods beyond ticks and mosquitoes for a search of emerging arthropod-borne pathogens.

    The link between central Greenland stable oxygen isotopes, atmospheric blocking frequency and cold temperature extremes at decadal to multidecadal time scales is investigated using observed and proxy data as well as model experiments. A composite analysis reveals that positive stable isotope anomalies in central Greenland are associated with enhanced blocking activity in the Atlantic European region. Several indices of blocking activity in the Atlantic European region are higher correlated with central Greenland stable isotope time series than with the North Atlantic Oscillation indices both in observations and model simulation. Furthermore, the blocking frequency anomaly pattern associated with central Greenland stable isotope variability is similar to the blocking anomaly pattern associated with the Atlantic Multidecadal Oscillation. A composite analysis reveals that stable isotope variations in central Greenland are related to a large-scale pattern in the frequency of extreme low temperature events with significant positive anomalies over Europe and a southwest to northeast dipolar pattern over Asia. During observational period central Greenland isotope records, blocking and extreme temperature indices over Europe show enhanced variability 10-30 and 50-70 years. Similar quasi-periodicities dominate the spectrum of central Greenland isotope variability during the last millennium. We argue that long-term variations of climate extreme indices over Europe and Asia, as derived from observational data, can be put into a long-term perspective using central Greenland stable isotope ice core records.

  11. The "Geomorphologic Diagonal" of Central Europe - towards a new morphotectonic interpretation of macroforms in average mountains

    2016-04-01

    Modern methods of low temperature thermochronology are able to throw light on the geomorphological development of macrorelief landforms. A rarely investigated problem concerns the orientation and morphotectonic evolution of Central European uplands (low to mid-elevation mountain ranges). A conspicuous NW-SE striking boundary takes course through Germany from the Osning and Teutoburg Forest in the NW to the Bavarian Forest in the SE. I call this line the "geomorphological diagonal". East of this line, more or less NW-SE striking morphotectonic features (e.g., Harz Mountains, Sudety) dominate the macrorelief up to the eastern border of Central Europe (Thornquist-Teysseire Lineament), with the exception of the Ohre Rift and Central Bohemia. West of this line, the macrorelief is either characterized by NNE-SSW to N-S oriented structures (e.g., Upper Rhine Rift) and, to a lesser extent, by (S)SW-(E)NE mountain ranges (southern Rhenish Slate Mountains and Ore Mountains) or by no predominance at all. In the Lower Rhine Embayment and along the Middle Rhine River, (N)NW-(S)SE directed morphotectonic features influence the low mountain ranges. In several cases geologists have proven that NW-SE morphotectonic structures are related to the Upper Cretaceous (Santonian to Campanian) "basin inversion" (e.g., von Eynatten et al. 2008). A compilation of low temperature thermochronological data (AFT, [U-Th]/He) from Central Europe clearly supports strong crustal cooling during the Upper Cretaceous and lowermost Tertiary in morphotectonically protruded crustal blocks east of the geomorphological diagonal, whereas west of it the age data available so far exhibit a much larger scatter from Upper Paleozoic to Tertiary without clear evidence of an outstanding Upper Cretaceous crustal cooling event. Based on this data I hypothesize that east of the diagonal macroforms of uplifted denudation surfaces ("peneplains" or "etchplains") may be inherited from the Cretaceous whereas west of it

  12. The hot day frequency of summer 2015 in Central Europe - correspondence with monthly circulation types

    The summer 2015 was characterized by at least three heat waves in Central Europe and a distinct anomaly of hot day frequency (defined by days exceeding the 90th percentile temperature of the period 1950 to 2015 of a Central Europe temperature index inlcuding data from several stations). In order to examine the role of the atmospheric circulation (represented by NCEP-NCAR reanalysis geopotential heights), a circulation type classification based on a cluster analysis conditioned on hot day frequency has been developed for mean values of the months June, July and August 1950 to 2015. In order to optimize the classification, geopotential heights of several levels have been evaluated whereas the 200 hPa level showed highest explained cluster variances. Also four different spatial domains (ranging from the hemispheric to the regional scale) have been tested. However, the smallest one (5-15°E/45-55°N) was the best. Since the hot day frequency was included in the cluster analysis an optimal weight for this variable compared to the circulation data has to be found. Therefore weights beginning at w=0.01 up to 10 have been iteratively increased, while for each weight an ensemble of three random samples has been drawn for clustering, while 25% of the sample have been kept for evaluation, i.e. calculating the explained cluster variance. Thus an optimal weight of w=0.4 has been determined which produced an explained variance of r²=0.64 for the hot day frequency. A remarkable correspondence between the occurrence of summer months with high hot day frequencies together with two anticyclonic circulation types limited to the second half of the examination period (occurrence only after 1980) has been found and is discussed.

    Annually laminated (varved) sediments with defined event-based age anchor points such as tephra layers enable the establishment of precise chronologies in lacustrine climate archives. This is especially useful to study subtle temporal differences in the consequences of mechanisms and feedbacks during abrupt climatic changes such as the Younger Dryas over larger spatial areas. To decipher the drivers of ecological changes across the Allerød/Younger Dryas transition in central Europe, we analyzed leaf wax biomarkers from Trzechowskie paleolake in northern Poland. Samples were taken in 10 years intervals across the onset of the Younger Dryas, with the Laacher See Tephra (12,880 yrs BP) as anchor point for age-calibration. Further, we applied compound specific hydrogen isotope analysis to infer past hydrological changes, in comparison to results from the well-dated Meerfelder Maar record located up 900 km to the southwest [1]. Between 12,750 and 12,600 yrs BP, ratios of terrestrial n-alkanes show a transition from a tree-dominated lake catchment (Pinus, Betula) to an environment mainly covered by Juniperus and grasses, which is in agreement with palynological data. δD values of n-alkanes indicate a rapid cooling and/or a change of moisture source together with a slight aridification between 12,680 and 12,600 yrs BP. This is synchronous to a rapid and strong aridification inferred for the beginning of the Younger Dryas at Meerfelder Maar (western Germany) [1] but ca. 170 yrs after the inferred onset of cooling at both Meerfelder Maar and the NGRIP ice core at 12,850 yrs BP. This highlights a different temporal succession and impact of hydrological and climatic changes in eastern compared to western Europe which could potentially be related to the stronger influence of the Fennoscandian icesheets and/or the Siberian High on atmospheric circulation patterns in the more continental climate influenced parts of eastern Europe.

  18. Human impact and colluvial sediment storages in Central Europe since the Neolithic

    NASA Astrophysics Data System (ADS)

    Schlummer, Manuela; Hoffmann, Thomas

    2010-05-01

    The adoption of agricultural techniques during the early Neolithic persistently affected sediment fluxes in geomorphic hillslope and adjacent river systems. Since then soil erosion and colluviation has become important geomorphic processes in hillslope-channel-systems. Soil erosion in turn affected human societies by soil degradation causing dramatic shifts of settlement centres. Erosion induced soil degradation initiated by land use activities is considered as a major link between the interaction of humans and their environment. To test this hypothesis a large-scale synoptic analysis of local case studies is currently under progress within the Collaborative Research Centre "Our Way to Europe", which deals with human environmental interaction and human mobility in the late Quaternary. In this study it is intended to achieve the following four aims: i) a reconstruction of the spatial trajectory of the beginning colluvial process, ii) the identification of crucial controlling factors of colluviation, iii) the quantification of colluvial sediment storage in Central Europe, iv) a spatio-temporal analysis of the colluviation process. The methodological approach includes the compilation of a colluvial database for Central Europe containing information on sediment depth, volumes, sedimentation rates and sediment ages. The database will be completed by own data collections in a small catchment and by calculating a sediment budget for the Pleisbach catchment (Pleiser Hügelland, near Bonn, Germany). Based on this colluvial data an isoline map of the spatial variable starting times of colluviation is generated. The isolines will be compared to archaeological maps of European neolithisation in order to identify stagnancies in expansion of Neolithic techniques in colluvial sediment archives. Furthermore a semi-quantitative erosion index will be developed that integrates qualitative information on controlling factors of colluviation, i. e. vegetation, land use, settlement

  19. A tectonic model for the spatial occurrence of porphyry copper and polymetallic vein deposits - applications to Central Europe

    A structural-tectonic model, which was developed to assess the occurrence of undiscovered porphyry copper deposits and associated polymetallic vein systems for the Matra Mountains, Hungary, has been expanded here and applied to other parts of central Europe. The model explains how granitoid stocks are emplaced and hydrothermal fluids flow within local strain features (duplexes) within strike-slip fault systems that develop in continental crust above subducting plates. Areas of extension that lack shear at the corners and along the edges of the fault duplexes are structural traps for the granitoid stocks associated with porphyry copper deposits. By contrast, polymetallic vein deposits are emplaced where shear and extension are prevalent in the interior of the duplexes. This model was applied to the Late Cretaceous-age porphyry copper and polymetallic vein deposits in the Banat-Timok-Srednogorie region of Romania-Serbia-Bulgaria and the middle Miocene-age deposits in Romania and Slovakia. In the first area, porphyry copper deposits are most commonly located at the corners, and occasionally along the edges, of strike-slip fault duplexes, and the few polymetallic vein deposits identified are located at interior sites of the duplexes. In the second area, the model accounts for the preferred sites of porphyry copper and polymetallic vein deposits in the Apuseni Mountains (Romania) and central Slovakian volcanic field (Slovakia).

    The serious environmental problems caused by decades of Communist mismanagement of natural resources in countries of Central and Eastern Europe have been brought to light in recent years. All environmental media, including air, water, food, and soil have been burdened with toxic chemicals. Large segments of the population have been, and are now being exposed to air pollution levels exceeding guidelines established by western countries and by international health organizations. This review focuses on epidemiologic evidence regarding health effects of poor air quality in Central and Eastern Europe. It appears that short-term high levels of air pollutants (primarily particulates and SO{sub 2}) may increase mortality in sensitive parts of the population. Associations were also seen between air pollution levels and prevalence of respiratory diseases as well as lung function disturbances in adults and children. One study indicated that urban air pollution increased the risk of lung cancer. Several investigations pointed to strong interactions between risk factors. The poor scientific standard of the studies often makes it difficult to evaluate the findings. Several steps should be taken to develop environmental epidemiology in Central and Eastern Europe, including international collaboration in research projects and training. 30 refs., 1 fig., 11 tabs.

  1. Direct radiative effect modeled for regional aerosols in central Europe including the effect of relative humidity

    In view of both the climatic relevance of aerosols and the fact that aerosol burdens in central Europe are heavily impacted by anthropogenic sources, this study is focused on estimating the regional-scale direct radiative effect of aerosols in Austria. The aerosol data (over 80 samples in total) were collected during measurement campaigns at five sampling sites: the urban areas of Vienna, Linz, and Graz and on Mt. Rax (1644 m, regional background aerosol) and Mt. Sonnblick (3106 m, background aerosol). Aerosol mass size distributions were obtained with eight-stage (size range: 0.06-16 μm diameter) and six-stage (size range 0.1-10 μm) low-pressure cascade impactors. The size-segregated samples were analyzed for total carbon (TC), black carbon (BC), and inorganic ions. The aerosol at these five locations is compared in terms of size distributions, optical properties, and direct forcing. Mie calculations are performed for the dry aerosol at 60 wavelengths in the range 0.3-40 μm. Using mass growth factors determined earlier, the optical properties are also estimated for higher relative humidities (60%, 70%, 80%, and 90%). A box model was used to estimate direct radiative forcing (DRF). The presence of absorbing species (BC) was found to reduce the cooling effect of the aerosols. The water-soluble substances dominate radiative forcing at the urban sites, while on Rax and Sonnblick BC plays the most important role. This result can be explained by the effect of the surface albedo, which is much lower in the urban regions (0.16) than at the ice and snow-covered mountain sites. Shortwave (below 4 μm) and longwave surface albedo values for ice were 0.35 and 0.5, while for snow surface albedo, values of 0.8 (shortwave) and 0.5 (longwave) were used. In the case of dry aerosol, especially for urban sites, the unidentified material may contribute a large part to the forcing. Depending on the sampling site the estimated forcing gets more negative with increasing humidity

    Campylobacteriosis is the leading zoonosis in the European Union with the majority of cases attributed to Campylobacter jejuni. Although the disease is usually self-limiting, some severe cases need to be treated with antibiotics, primarily macrolides and quinolones. However, the resistance to the latter is reaching alarming levels in most of the EU countries. To shed light on the expansion of antibiotic resistance in central Europe, we have investigated genetic similarity across 178 ciprofloxacin-resistant C. jejuni mostly isolated in Slovenia, Austria and Germany. We performed comparative genetic similarity analyses using allelic types of seven multilocus sequence typing housekeeping genes, and single nucleotide polymorphisms of a quinolone resistance determining region located within the DNA gyrase subunit A gene. This analysis revealed high genetic similarity of isolates from clonal complex ST-21 that carry gyrA allelic type 1 in all three of these central-European countries, suggesting these ciprofloxacin resistant isolates arose from a recent common ancestor and are spread clonally.

    We processed all freely available data in Europe, from 1990 to October 2013, obtained through theEuropean Integrated data archive (EIDA) to calculate surface wave phase velocity maps. With anautomated inter-station method, we have obtained highly consistent, high quality, very broad band(10 s ->200 s), phase velocity measurements for both Love and Rayleigh waves. We performedmore than 8 million cross correlations to obtain around 1.5 million individual phase velocitymeasurements. Path-wise averaging resulted in more than 22,000 average dispersion curves fordifferent inter-station paths, with an average standard deviation of less than 1.5%. These averagephase velocity dispersion curves are then used to obtain Love and Rayleigh wave phase velocitymaps. We carried out number of resolutions tests to check the reliability of the isotropic and anisotropiccomponents of the maps. A quasi checkerboard test shows the areas of the best sampling, while thereliability of azimuthal anisotropy is tested using a synthetic model with fast directions at 90° tothose in the actual phase velocity maps. The results of the tests show that we obtain a lateralresolution from 100 to 200 km. At shortest periods (10 s) the isotropic maps clearly image the Central European basin system(CEBS) extending from north German basin in the north towards the Polish basin further southeast.In southern Central Europe low velocities are associated with thick sedimentary cover in the Pobasin and in the Pannonian basin. At these periods, there is a N-S trend of the anisotropy in thenorth, and E-W trend in the Alpine region in south, and in the Pannonian basin. Remarkably,isotropic velocities of the central European mantle lithosphere show no imprint of the Caledonianand Variscan sutures. In the uppermost mantle, a sharp lateral gradient at the Teisseyre-Tornquist-Zone (TTZ) is observed as compared to a more gradual lateral transition across the Sorgenfrei-Tornquist-Zone (STZ). We denote the shallow

    Beginning in 1997, Central Europe has been covered by an unprecedented network of seismic refraction experiments. These experiments (POLONAISE'97, CELEBRATION 2000, ALP 2002, SUDETES 2003) have only been possible due a massive international cooperative effort. The total length of all profiles is about 19,000 km, and over 300 explosive sources were employed. The result is a network of seismic refraction profiles that extends along the Trans-European Suture Zone region of Poland and the Bohemian massif, Pannonian basin, trough the Carpathians and Alps to the Adriatic Sea and the Dinarides. As reflected in structures within these areas, Central Europe has experienced a complex tectonic history that includes the Caledonian, Variscan, and Alpine orogenies. The related TESZ region is a broad zone of deformation that extends across Europe from British Isles to the Black Sea region that formed as Europe was assembled from a complex collage of terranes during the late Palaeozoic. For example, the Bohemian massif is mostly located in the Czech Republic and is a large, complex terrane whose origin can be traced to northern Gondwana (Africa). These terranes were accreted along the margin of Baltica that was formed during the break-up of Rodinia. The tectonic evolution of this region shares many attributes with the Appalachian/Ouachita origin and is certainly of global important to studies in terrane tectonics and continental evolution. In southern Poland, several structural blocks are located adjacent to Baltica and were probably transported laterally along it similar to the Cenozoic movement of terranes along the western margin of North America. The younger Carpathian arc and Pannonian back-arc basin were also targeted by these experiments. Thickness of the crust in the area of investigations changes from 22-25 km in the Pannonian basin to about 55 km in the Trans-European Suture Zone in SE Poland. Together, these experiments are providing an unprecedented 3-D image of the

    Background and objectives HIV among people who inject drugs (PWID) is a major public health concern in Eastern and Central Europe and Central Asia. HIV transmission in this group is growing and over 27 000 HIV cases were diagnosed among PWID in 2010 alone. The objective of this systematic review was to examine risk factors associated with HIV prevalence among PWID in Central and Eastern Europe and Central Asia and to describe the response to HIV in this population and the policy environments in which they live. Design A systematic review of peer-reviewed and grey literature addressing HIV prevalence and risk factors for HIV prevalence among PWID and a synthesis of key resources describing the response to HIV in this population. We used a comprehensive search strategy across multiple electronic databases to collect original research papers addressing HIV prevalence and risk factors among PWID since 2005. We summarised the extent of key harm reduction interventions, and using a simple index of ‘enabling’ environment described the policy environments in which they are implemented. Studies reviewed Of the 5644 research papers identified from electronic databases and 40 documents collected from our grey literature search, 70 documents provided unique estimates of HIV and 14 provided multivariate risk factors for HIV among PWID. Results HIV prevalence varies widely, with generally low or medium (<5%) prevalence in Central Europe and high (>10%) prevalence in Eastern Europe. We found evidence for a number of structural factors associated with HIV including gender, socio-economic position and contact with law enforcement agencies. Conclusions The HIV epidemic among PWID in the region is varied, with the greatest burden generally in Eastern Europe. Data suggest that the current response to HIV among PWID is insufficient, and hindered by multiple environmental barriers including restricted access to services and unsupportive policy or social environments.

    The summer of 2010 was characterized by severe weather events such as floods, heat waves and droughts across Middle East, most of Europe and European Russia. Among them the wildfires in Portugal and European Russia were some of the most prominent and led to substantial increase of atmospheric aerosols concentration. For instance, pollution from Russian wildfires, which were the most noticeable, spread around the entire central part of the country and also dispersed towards the Northern Europe. This study is devoted to Enviro-HIRLAM (Environment - HIgh Resolution Limited Area Model) model evaluation and analysis of radiation balance change due to increased aerosol burden caused by wildfires in Russia. For this purpose the model was forced by boundary and initial conditions produced by ECMWF (European Center for Medium-Range Weather Forecast) IFS and MOZART models for meteorology and atmospheric composition, respectively. The model setup included aerosol microphysics module M7 with simple tropospheric sulfur chemistry, anthropogenic emissions by TNO, wildfires emissions by FMI and interactive sea-salt and dust emissions. During the model run surface data assimilation of meteorological parameters was applied. The HIRLAM Savijarvi radiation scheme has been improved to account explicitly for aerosol radiation interactions. So that the short-wave radiative transfer calculations are performed as standard 2-stream calculations for averages of aerosol optical properties weighted over the entire spectrum. The model shows good correlation of particulate matter (PM) concentrations on diurnal cycle as well as day-to-day variability, but one always has negative bias of PM. The Enviro-HIRLAM is able to capture concentration peaks both from short-term and long-term trans boundary transport of PM and predicted the Aerosol Optical Thickness (at 550 nm) up to 2 over wildfire-polluted regions. And the direct radiative forcing is less than -100 W/m2.

    Knowledge of past climate variability based on the study of paleoclimate archives may help in better understanding the forcing mechanisms and extent of any future climate change. In some regions, such as Eastern Europe, loess-paleosol sequences (LPS) are one of the most important terrestrial archives of Quaternary paleoclimate and its spatial and temporal dynamics. Studies of LPS from the Middle and Lower Danube basins fundamentally improved understanding of the European Quaternary climate and environmental evolution. The central Balkans (central Serbia) is situated in a transition zone between the temperate-continental climate zone to the north and Mediterranean climate to the south. Up to now this area has been poorly investigated concerning the paleoclimate evolution on a longer term, albeit this region is considered more sensitive to the relative influence associated to the Mediterranean climate influence than the Carpathian basin further north. To fill this gap we conducted a high-resolution multiproxy investigation on the Stalać LPS in the central Balkan (Serbia). Located at the southern limits of European loess distribution and within the Mediterranean climate influence, the Stalać section has potential for better understanding of past regional climate dynamics. We discuss grain-size (granulometric fractions, U-ratio), environmental magnetic (χ, χfd), geochemical (major and trace elements) and colour (L*, a*, b* values) data from the Stalać section in terms of switching sediment provenance sources modulated by past environmental conditions. We can show that the Carpathian Basin and central Balkans were influenced by different environmental conditions during past ~350 ka. A general higher continentality of the climate during the late Pleistocene can be observed over the Stalać section and the Carpathian Basin, indicating that this trend is more than a regional feature. Our results indicate warmer and/or more humid last glacial cycles compared to

    Early life conditions play an important role in determining adult body size. In particular, childhood malnutrition and disease can elicit growth delays and affect adult body size if severe or prolonged enough. In the earliest stages of farming, skeletal growth impairment and small adult body size are often documented relative to hunter-gatherer groups, though this pattern is regionally variable. In Central/Southeast Europe, it is unclear how early life stress, growth history, and adult body size were impacted by the introduction of agriculture and ensuing long-term demographic, social, and behavioral change. The current study assesses this impact through the reconstruction and analysis of mean stature, body mass, limb proportion indices, and sexual dimorphism among 407 skeletally mature men and women from foraging and farming populations spanning the Late Mesolithic through Early Medieval periods in Central/Southeast Europe (~7100 calBC to 850 AD). Results document significantly reduced mean stature, body mass, and crural index in Neolithic agriculturalists relative both to Late Mesolithic hunter-gatherer-fishers and to later farming populations. This indication of relative growth impairment in the Neolithic, particularly among women, is supported by existing evidence of high developmental stress, intensive physical activity, and variable access to animal protein in these early agricultural populations. Among subsequent agriculturalists, temporal increases in mean stature, body mass, and crural index were more pronounced among Central European women, driving declines in the magnitude of sexual dimorphism through time. Overall, results suggest that the transition to agriculture in Central/Southeast Europe was challenging for early farming populations, but was followed by gradual amelioration across thousands of years, particularly among Central European women. This sex difference may be indicative, in part, of greater temporal variation in the social status afforded

    The expansion and retreat of the ice sheet is controlled by climate changes, and from the other hand, a huge ice mass influences on the climate in the regional scale. This mechanism is commonly known as the fact but often without making reconstruction by using climatological modeling. The purpose of our study is to reconstruct the climate condition during the Weichselian Ice Sheet in the Central Europe, especially for Poland and surrounded countries. The Global Climate Model (GCM) is made for predicting climate, but simplified version can be useful for reconstructing paleoclimate. Hence, the simple initial conditions and surface data proposed by the Educational version of the GCM was applied. In our study we used a simplified version of the GCM to calculate main climate characteristics within the time limits c. 21 000 BP - 18 000 BP, which has been previously invented on Columbia University. The model is constructed on grid with a horizontal resolution 8° latitude by 10° longitude and was establish for modeling most of weather conditions based on available paleoclimate data. It is possible to estimate the probable climate condition along the southern ice sheets margin on the basis of output from the GCM and GIS modeling techniques. Above the ice mass occurs local high pressure area, which seriously interfered on atmospheric circulation. Whereas the low pressure systems in the southern part of continent may caused permanent barometric situation, which stimulates wind directions as well as the precipitable water available in the mass of air. The climate on the east-south border of ice margin was colder and drier than on the west-south region, where it was more ocean-reliable and gentle with higher temperatures. The differences in temperature between the western and eastern part of the Central Europe reached few centigrade. Against a background of the mean paleoclimatic situation in the Central Europe there is coming out a question about the particular paleoclimate

    Sprites are luminous optical emissions accompanying electric discharges in the mesosphere. 489 sprite events have been observed with a TV frame rate video system in Central Europe from Sopron (47.68°N, 16.58°E, ˜230 m MSL), Hungary between 2007 and 2009. Characteristic sprite forms, i.e., column, wishbone, tree, angel, and carrot have been identified in the set of records. Characteristic morphological properties corresponding to each type are given; earlier definitions and observations as well as the related theoretical considerations are reviewed. Based on the knowledge and experience from high-speed imaging in sprite observations, probable time sequences of streamer propagation directions were associated with the characteristic sprite types. It is suggested that different streamer propagation sequences corresponding to different dynamic processes may result in similar sprite forms. Several occasionally detectable sprite features are noted and described: tendrils, glows, puffs, beads, and spots. Spots are distinguished from the similar beads by their characteristic brightness, size, and location relative to the bright body of the sprite. The events observed in Central Europe have been classified by the number of individual sprites and by the variety of types appearing in them. More than 90% of the recorded sprites were found to occur in clusters rather than alone, and more than half of the sprite clusters contained more than one sprite types. Jellyfish and dancing sprite events are described as being special subsets of sprite clusters. Statistical analysis of the occurrences of morphological types, various sprite features, and event durations indicated that jellyfish sprites and clusters of column sprites with glows and tendrils do not tend to have long optical lifetimes. Sprite events with more morphological types, on the other hand, more likely have extended durations. The maximum of the encountered event duration was lower for events with many sprite

    Many contemporary studies of climate change focused on or including Central Europe suggest significant changes of future climate characteristics. The scope of this transformation includes increased mean annual temperature, increased frequency and intensity of heat waves and droughts and changes in spatiotemporal precipitation characteristic including the tendency to occurrence of dangerous torrential rains. This makes from the region one of the particularly vulnerable area increasing the necessity of providing reliable, precise and comprehensible information both to the decision makers and general public. In our study we decided to examine climate change signal using the Köppen-Geiger climate classification on corrected output of high resolution simulations performed with the RCMs ALADIN-Climate/CZ and RegCM, nested in GCM ARPÉGE 5.0 lateral boundary conditions and ECHAM4 respectively. Both experiments were forced by IPCC SRES A1B scenario. Climate classifications like that of Köppen-Geiger are useful in wider range of ecological disciplines including forestry and agriculture as they correlate with their bio-ecologically oriented classification systems. In order to address regional and local character of climate change signal we decided to study simulations performed in 10km resolution, which is capable to capture even relatively fine scale geomorphological details. To retain as much fine scale signal as possible, model output was corrected using measured data from the dense observation networks operated by the national meteorological services of Austria (north to the Alps), Czech Republic and Slovakia. Thus, we are able to detect changes in climate characteristics affecting small scale geomorphological features like individual Alps and Carpathian mountain ranges, individual mountain systems of Bohemian massif, rift and river valleys, which are usually poorly represented in more coarse resolution. Our findings among other suggest the risk of large scale

    The increasingly dense coverage of Europe with broad-band seismic stations makes it possible to image its lithospheric structure in great detail, provided that structural information can be extracted effectively from the very large volumes of data. We develop an automated technique for the measurement of interstation phase velocities of (earthquake-excited) fundamental-mode surface waves in very broad period ranges. We then apply the technique to all available broad-band data from permanent and temporary networks across Europe. In a new implementation of the classical two-station method, Rayleigh and Love dispersion curves are determined by cross-correlation of seismograms from a pair of stations. An elaborate filtering and windowing scheme is employed to enhance the target signal and makes possible a significantly broader frequency band of the measurements, compared to previous implementations of the method. The selection of acceptable phase-velocity measurements for each event is performed in the frequency domain, based on a number of fine-tuned quality criteria including a smoothness requirement. Between 5 and 3000 single-event dispersion measurements are averaged per interstation path in order to obtain robust, broad-band dispersion curves with error estimates. In total, around 63,000 Rayleigh- and 27,500 Love-wave dispersion curves between 10 and 350 s have been determined, with standard deviations lower than 2 per cent and standard errors lower than 0.5 per cent. Comparisons of phase-velocity measurements using events at opposite backazimuths and the examination of the variance of the phase-velocity curves are parts of the quality control. With the automated procedure, large data sets can be consistently and repeatedly measured using varying selection parameters. Comparison of average interstation dispersion curves obtained with different degrees of smoothness shows that rough perturbations do not systematically bias the average dispersion measurement. They

    data support the notion that the fraction of plutonium-derived Xe in plume sources (oceanic as well as continental) is higher than in the MORB source reservoir. Hence, the MORB - type reservoirs appear to be well distinguished and more degassed than the plume sources (oceanic as well as continental) supporting the heterogeneity of Earth's mantle. Finally this study highlights that xenon isotopes in the Eifel gas have preserved a chemical signature that is characteristic of other mantle plume sources. This is very intriguing because the presence of a mantle plume in this sector of Central Europe was already inferred from geophysical and geochemical studies(Buikin et al., 2005; Goes et al., 1999). Notably, tomographic images show a low-velocity structure down to 2000 km depth, representing deep mantle upwelling under central Europe, that may feed smaller upper-mantle plumes (Eifel volcanic district-Germany).

    The CEGRN 2011 Campaign took place from 20 to 25 June 2011. It was a coordinated effort of 14 Central European Countries: Austria, Bosnia Herzegovina, Bulgaria, Croatia, Czech Republic, Germany, Hungary, Italy, Poland, Rumania, Serbia, Slovakia, Slovenia and Ukraine, with the involvement of some 85 stations. Data processing with state of the art software, and IGS08 orbits and antenna models according to the EPN standards is being completed by independent Analysis Centers in Austria, Hungary, Italy and Slovakia, with the Center in Graz acting as a Combination Center. The paper presents the results of the analysis and of the multiyear combination, with time series spanning a timeline of up to 17 years (1994-2011). Since all data up to and including the 2009 Campaign have been re-analysed with the reprocessed orbits and IGS05 antenna models, the derived velocity field represents a particularly valid example of evolution of the ITRF reference frame in Central Europe. The addition of the 2011 data set, based on IGS08, is not obvious. In a first step the solution, inclusive of the 2011 campaign, can be aligned to the EPN (European Permanent Network of EUREF) cumulative solution in ITRF2005 and can be transformed into the ETRF2000 frame. In a second step, the CEGRN campaigns are planned to be reprocessed with the IGS08 antenna models, provided the IGS and EPN reprocessing solutions (REPRO2) are available for the orbits. Once completed, a densification of the European regional velocity field will become available for both geodynamic studies and widespread dissemination of the ETRS89 standard of coordinates, in compliance with the EU Directive INSPIRE.

  20. Scientific Migration in Central Europe in the Context of the Cold War

    As a way of intellectual reparations the Allies tried in 1945 to capture German scientists to undertake research in their own R& D and military research projects. The Soviet Occupied Zone of Germany was particularly strongly affected by this seizure of its scientific elite. Among the displaced were a group of leading German physicists, who were assigned to specific laboratories in the Caucasus, where they were kept like precious birds in a golden cage advancing the Soviet atomic bomb project. These included the Nobel Laureate Gustav Hertz, Manfred von Ardenne, Peter Adolf Thiessen and Max Steenbeck, to name but a few. In contrast to many others in similar circumstances, the fate of these scientists was directly influenced by the nuclear race and the Cold War as a result of which they were unable to return to Germany before 1955. Many German returnee scientists settled in East Germany, but some enjoyed successful careers in the West. Remarkably, one of the most instrumental inventions of the nuclear age -- the ultracentrifuge used for uranium enrichment -- emerged from this ``gilded cage.'' However, the 1950s were also marked by other migrations as well as by processes of science and technology transfer. In particular, there was an exodus of many scientists from East to West, which was driven by a lack of political freedom and prospertity and exacerbated by political turmoil in Central Europe during this period (1953/1956/1961/1968). My talk will provide a brief account of these migratory processes with a focus on Germany. Migrations concerning other Central European countries such as Czechoslovakia, Hungary, and Poland will be also briefly described in a comparative perspective and illustrated with examples about the life and work of several physicists.

    Psychosocial factors at work have been found to predict a range of health outcomes but their effect on mental health outcomes has not been extensively studied. This paper explores the relationship between psychosocial factors at work and depression in three countries of Central and Eastern Europe. The data come from a cross-sectional study of working men (n = 645) and women (n = 523) aged 45-64 years, randomly selected from population registers in Novosibirsk (Russia), Krakow (Poland) and Karvina-Havirov (Czech Republic). The questionnaire included questions on the effort and reward at work, job control, the full CES-D scale of depression, and a range of other characteristics. Linear regression was used to estimate the association between depression score and work characteristics: the logarithm of the effort-reward ratio, and continuous job control score. The means of the depression score were 10.5 for men and 14.2 for women. After controlling for age, sex and country, effort-reward ratio (logarithmically transformed) was strongly related to depression score; a 1 SD increase in the log transformed effort-reward ratio was associated with an increase in the depression of 2.0 points (95% CI 1.5; 2.4), and further adjustment did not materially change the effect. Job control was inversely associated with depression score in Poland and the Czech Republic (not in Russia) but the association was largely eliminated by controlling for socioeconomic characteristics. This study suggests that the effort-reward imbalance at work is related to prevalence of depression in these central and eastern European populations.

    In July 2013 very strong boreal fire plumes were observed at the northern rim of the Alps by lidar and ceilometer measurements of aerosol, ozone and water vapour for about 3 weeks. In addition, some of the lower-tropospheric components of these layers were analysed at the Global Atmosphere Watch laboratory at the Schneefernerhaus high-altitude research station (2650 m a.s.l., located a few hundred metres south-west of the Zugspitze summit). The high amount of particles confirms our hypothesis that fires in the Arctic regions of North America lead to much stronger signatures in the central European atmosphere than the multitude of fires in the USA. This has been ascribed to the prevailing anticyclonic advection pattern during favourable periods and subsidence, in contrast to warm-conveyor-belt export, rainout and dilution frequently found for lower latitudes. A high number of the pronounced aerosol structures were positively correlated with elevated ozone. Chemical ozone formation in boreal fire plumes is known to be rather limited. Indeed, these air masses could be attributed to stratospheric air intrusions descending from remote high-latitude regions, obviously picking up the aerosol on their way across Canada. In one case, subsidence from the stratosphere over Siberia over as many as 15-20 days without increase in humidity was observed although a significant amount of Canadian smoke was trapped. These coherent air streams lead to rather straight and rapid transport of the particles to Europe.

    Aim To provide insights into the capacity to conduct health technology assessment (HTA) in Central, Eastern, and South-Eastern Europe (CESEE), taking account of technical, financial, networking, and human resources. Methods An e-mail survey of 257 CESEE key informants involved in HTA was undertaken between March and April 2014. Contact e-mail addresses were identified from the internet. The survey questionnaire consisted of 3 sections: i) characteristics of the organization performing HTA, (ii) networking in HTA, and (iii) resources allocated for HTA. Results The survey was completed by 41 respondents representing a wide range of institutions from CESEE countries (response rate of 19.8%). Less than a quarter of respondents reported that their institutions had HTA-specific budgets, whereas the majority indicated that their institutions participated in HTA networks either at domestic or international levels. Although almost half of respondents indicated that their institutions offered HTA training, a shortage in skills training was suggested as the main barrier to HTA. Conclusion This is the first survey to thoroughly assess the state of HTA capacity in the CESEE region. To strengthen HTA capacity, CESEE countries should increase financial, technical, and training resources. To strengthen collaboration, the European Union and other international bodies should assist existing HTA networks in fulfilling their regional activities through leadership, advocacy to local policymakers, funding, and technical assistance.

    This work presents dynamically downscaled near-surface wind speed fields and examines the impact of climate changes on wind speed across central Europe. The analysis is based on regional model simulation (5 RCM simulations taken from the project PRUDENCE and CLM regional climate model from M&D group) forced by IPCC emission scenario SRES - A2. Each model provided data from two 30-year simulations: a control run under present day climate conditions for the period 1961-90 and a simulation under conditions projected for the period 2021-2050. The research domain covered region from 42°N to 62°N and from 6°E to 36°E. The model ensemble shows a possible increase in future mean wind speed during winter season, especially over zonal belt from North German to North Poland where the future mean wind speed is 0.4 m/s higher than in the control period. The projected climate change in summer over most research domain shows a decrease of mean wind speed (about 0.2 m/s). The Jutland Peninsula and North German is the region with the highest simulated wind speed. The simulated changes are more pronounced in 95th percentile than in the mean. In winter, the values of the 95th percentile will increase over the North German, Jutland Peninsula and North Poland but the highest change is projected over east coast of Baltic Sea (1m/s).

    Abrupt climate shifts during the last deglaciation provide test cases for analyzing the transient response of our climate system to changes in external forcings and internal feedbacks. The regional imprints of rapid climate shifts, their timing and hence connection to local vs. large-scale mechanisms are however still poorly understood owing to a limited number of records with usually large age uncertainties and low sampling rates. In this study we examine the spatiotemporal evolution of rapid climate shifts over central Europe and Scandinavia during Bølling-Allerød (14.7-12.7kyr BP) and Younger Dryas (~12kyr BP) by means of pollen data and climate simulations. For a better understanding of physical mechanisms behind regional imprints of climate shifts, time slice experiments with the Community Earth System Model (CCSM1.0.5) are set up at high resolution (1°x1°) using different topographies and ice sheets (ICE-5G and a new version of GLAC). Matching these time slice experiments with the spatial temperature pattern derived from pollen records, we estimate the extent to which environmental conditions (pollen) represent the direct large-scale influence of climate over the Euro-Atlantic sector vs. regional-scale climate effects e.g. caused by shrinking ice sheets and coastal transgression due to sea-level rise.

    The systematic position and validity of species within genus Syngamus have always been controversial. In this present work, we evaluated the taxonomic status and phylogenetic relationships between three species of Syngamus nematodes (Syngamus trachea, Syngamus taiga and Syngamus merulae) and one taxa, determined only to the generic level, collected from respiratory tracts of passeriform hosts from Central Europe using newly obtained sequences of 2 nuclear markers (internal transcribed spacers 1 and 2 [ITS1, ITS2]) and a fragment of mitochondrial cytochrome oxidase I [COI] gene. Our results clearly showed that S. trachea, S. taiga and S. merulae are valid, molecularly and morphologically distinct species. Moreover, molecular analysis of adult female of Syngamus sp. collected from tracheae of the European robin Erithacus rubecula clearly indicate that these comprise separate species. In the derived phylogeny, the Syngamus clade is divided into two sub-clades: one comprised Syngamus species with a characteristic, well-developed cuticular collar around the oral opening (S. trachea and S. taiga) and a second that groups taxa without or with rudimentary collar (S. merulae and currently sequenced Syngamus sp. from Erithacus rubecula). These results clearly suggest that the degree of collar development (well-developed vs. rudimentary/absent) may be an important phylogenetic feature for determining the structure of the genus Syngamus on subgeneric level. Additionally, our results support historical division of the genus Syngamus into two subgenera S. (Syngamus) and S. (Ornithogamus).

  7. The legal status of home education in post-communist countries of Central Europe

    As new laws on education were gradually adopted in post-communist states after 1989, the countries also dealt with the problem of how to include home education in their own legislation. This article investigates the development of legislation on home education in five states of post-communist Central Europe: the Czech Republic, Slovakia, Slovenia, Poland and Hungary. This analysis of the legal environment for home education confirms on the one hand that these countries' approach is similar in many aspects. Generally, laws tend to regulate home education rather strictly, all home-educated children must be enrolled at some school, and these schools are mandated by the state to serve as supervisory bodies for home-educated children. This legal arrangement puts the parents of home-schooled children in a very subordinate position in relation to the school. Despite these restrictions, however, the states have gradually opened up the option for home education to quite a broad pool of potentially interested people. On the other hand, the findings show that there are also significant differences between individual countries. These differences provide a good illustration of the fact that, despite historical, economic and cultural similarities, political institutions and state bureaucracies in individual states act autonomously, which leads to different policy outcomes.

    Terrestrial isopods were collected in 13 forest fragments differing in area (within the range of 0.1 and 254.5 ha), shape and composition of forest vegetation (thermophilous oak, mesophilous oak-hornbeam, thermophilous oak-hornbeam, acidophilous oak, basiphilous oak, beech oak-hornbeam, moist mixed deciduous forest, plantations of deciduous and coniferous trees), all situated in the Český kras Protected Landscape Area, Czech Republic, Central Europe. Number of sites sampled in each fragment of forest depended on its size and ranged from 1 to 7. Altogether 30 sites were sampled. Soil samples (5 per site collected twice a year) and pitfall trapping (5 traps per site in continuous operation throughout a year) during 2008-2009 yielded a total of 14 species of terrestrial isopods. The highest densities and highest epigeic activities of terrestrial isopods were recorded in the smallest fragments of woodland. Although a wider range of habitats were sampled in the larger fragments of woodland there was not a greater diversity of species there and the population densities and epigeic activities recorded there were lower. Porcellium collicola was most abundant in small fragments of woodland regardless the vegetation there. Armadillidium vulgare and Protracheoniscus politus were statistically more abundant in the larger fragments of woodland. The results indicate that forest fragmentation does not necessarily result in a decrease in the species richness of the isopod assemblages in such habitats. PMID:22536108

    The phenological responses to climate of residents and migrants (short- and long-distance) differ. Although few previous studies have focussed on this topic, the agree that changes in phenology are more apparent for residents than for long-distance migrants. We analysed the breeding times of two selected residents (Sitta europaea, Parus major) and one long-distance migrant (Ficedula albicollis) from 1961 to 2007 in central Europe. The timing of the phenophases of all three bird species showed a significant advance to earlier times. Nevertheless, the most marked shift was observed for the long-distance migrant (1.9 days per decade on average in mean laying date with linearity at the 99.9% confidence level). In contrast, the shifts shown by the residents were smaller (1.6 days for S. europaea and 1.5 days for P. major also on average in mean laying date for both, with linearity at the 95% confidence level). Spearman rank correlation coefficients calculated for pairs of phenophases of given bird species in 20-year subsamples (e.g. 1961-1980, 1962-1981) showed higher phenological separation between the residents and the migrant. This separation is most apparent after the 1980s. Thus, our results indicate that the interconnections between the studied phenological stages of the three bird species are becoming weaker.

    The knowledge of evaluation of the intensity of cyclogenesis which could be connected with the weather having a significant impact on Earth's surface is quite useful. If, as one of the basic assumptions, the existence of connection between dry intrusions, dry bands, tropopause height and warm dark areas distribution on water vapor images (WV images) is considered, it is possible to set up a method of detecting dry intrusions on searching and tracking areas with higher brightness temperature compared with the surrounding environment. This paper covers the period between June 2010 and September 2011 over Central Europe. The ISIS method (Instrument de Suivi dans I'Imagerie satellitaire), originally developed for detection of cold cloud tops, was used as an initial ideological point. Subsequently, this method was modified by Michel and Bouttier for usage on WV images. Some of the applied criteria and parameters were chosen with reference to the results published by Michel and Bouttier as well as by Novotny. The procedure can be divided into two steps: detection of warm areas and their tracking. Cases of detection of areas not evidently connected with dry intrusions can be solved by filtering off based on the connection between detected warm areas to the cyclonic side of jet streams and significant lowering of the tropopause.

    The European Food Safety Authority (EFSA) guideline on risk assessment identifies pesticide exposure scenarios for nontarget wildlife; however, this scheme is not applicable to nonagricultural grassland. For example, different habitats and human utilization on golf courses attract bird communities that differ from those found in agricultural fields with annual crop cycles. The present study determined focal bird species for amenity grasslands such as golf courses following the EFSA guideline. Based on published data and bird surveys, a total of 102 species were found on 13 golf courses in Central Europe. Approximately 58% of the species were recorded on >20% of the golf course and were classified as focal species candidates. Common kestrel (Falco tinnunculus), common linnet (Carduelis cannabina), wood pigeon (Columba palumbus), yellowhammer (Emberiza citrinella), white wagtail (Motacilla alba), and gray heron (Ardea cinerea) are the most adequate candidate focal species for exposure scenarios of carnivorous, granivorous, herbivorous, omnivorous, insectivorous, and piscivorous birds, respectively. Candidate species were verified on 3 golf courses in southwestern Germany in spring 2012. Observations on feeding behavior identified the main foraging areas of focal species. The results of the field work combined with data from the literature identified reliable exposure scenarios to assess the risk of pesticides to birds found on golf courses.

    THE STRUCTURE, FUNCTION(S) and symbolism of early medieval (9th–10th centuries ad) fortified settlements from central Europe, in particular today’s Austria, Hungary, Czech Republic and Slovakia, are examined in this paper. It offers an overview of the current state of research together with new insights based on analysis of the site of Gars-Thunau in Lower Austria. Special emphasis is given to the position of the fortified sites in the landscape, to the elements of the built environment and their spatial organisation, as well as to graves within the fortified area. The region under study was situated on the SE border of the Carolingian (and later the Ottonian) Empire, with some of the discussed sites lying in the territory of the ‘Great Moravian Empire’ in the 9th and 10th centuries. These sites can therefore provide important comparative data for researchers working in other parts of the Carolingian Empire and neighbouring regions. PMID:23564981

    A new chronology of the last glaciation is established for the Krkonoše (Giant) Mountains, Central Europe, based on in-situ produced 10Be in moraine boulders. Exposure ages and Schmidt Hammer rebound values obtained for terminal moraines on the northern and southern flank of the mountains suggest that the oldest preserved moraines represent early phases of the Last Glacial Maximum (LGM). Large moraines at the outlet of the Snowy Cirques (Śnieżne Kotły) and in the middle part of the Úpa (Obří důl) trough were deposited around 21 ka while a series of smaller moraines above the LGM deposits represent readvances that occurred no later than 18.1 ± 0.6 ka, 15.7 ± 0.5 ka, 13.5 ± 0.5 ka and 12.9 ± 0.7 ka. An exposure age of 13.8 ± 0.4 ka obtained for protalus ramparts at the foot of the Úpská jáma Cirque headwall indicates that glaciers advanced only in north- to east-facing cirques during the Lateglacial. The last glacier fluctuation was synchronous with the Younger Dryas cold event. The timing of local glacier advances during the last glacial episode correlates with the late Weichselian glacier phases in the Alps and in the Bavarian/Bohemian Forest.

    Abstract Two new species, Pteromalus briani sp. n. and Pteromalus janstai sp. n., with unusual characters are described from the Central Plateau and the Alps in Switzerland, respectively. Pteromalus briani sp. n. is remarkable in that it has the metatibia quite abruptly expanded before the middle. This type of modification of the hind tibia is unique within the Pteromalidae and probably also the entire Chalcidoidea. It is also very rare in other parasitic wasps, where it is suspected to be associated with pheromone glands. The species is a gregarious endoparasitoid of pupae of Vanessa atalanta (Linnaeus) and Aglais urticae (Linnaeus), two common butterflies (Lepidoptera: Nymphalidae) in Europe. It is furthermore a koinobiont parasitoid ovipositing in an early larval stage of the host. The other species, Pteromalus janstai sp. n., shows a flattened mesosoma. A dorsoventrally depressed body is a unique feature within the genus Pteromalus, but known from a number species in unrelated genera and subfamilies. The two records demonstrate that it is possible to discover entirely new species with extraordinary characters even in one of the taxonomically most thoroughly explored parts of the world.

    In Central Europe, protected areas are too small to ensure survival of populations of large carnivores. In the surrounding areas, these species are often persecuted due to competition with game hunters. Therefore, understanding how predation intensity varies spatio-temporally across areas with different levels of protection is fundamental. We investigated the predation patterns of Eurasian lynx (Lynx lynx) on roe deer (Capreolus capreolus) and red deer (Cervus elaphus) in both protected areas and multi-use landscapes of the Bohemian Forest Ecosystem. Based on 359 roe and red deer killed by 10 GPS-collared lynx, we calculated the species-specific annual kill rates and tested for effects of season and lynx age, sex and reproductive status. Because roe and red deer in the study area concentrate in unprotected lowlands during winter, we modeled spatial distribution of kills separately for summer and winter and calculated-the probability of a deer killed by lynx and-the expected number of kills for areas with different levels of protection. Significantly more roe deer (46.05-74.71/year/individual lynx) were killed than red deer (1.57-9.63/year/individual lynx), more deer were killed in winter than in summer, and lynx family groups had higher annual kill rates than adult male, single adult female and subadult female lynx. In winter the probability of a deer killed and the expected number of kills were higher outside the most protected part of the study area than inside; in summer, this probability did not differ between areas, and the expected number of kills was slightly larger inside than outside the most protected part of the study area. This indicates that the intensity of lynx predation in the unprotected part of the Bohemian Forest Ecosystem increases in winter, thus mitigation of conflicts in these areas should be included as a priority in the lynx conservation strategy.

Based on 359 roe and red deer killed by 10 GPS-collared lynx, we calculated the species-specific annual kill rates and tested for effects of season and lynx age, sex and reproductive status. Because roe and red deer in the study area concentrate in unprotected lowlands during winter, we modeled spatial distribution of kills separately for summer and winter and calculated-the probability of a deer killed by lynx and-the expected number of kills for areas with different levels of protection. Significantly more roe deer (46.05–74.71/year/individual lynx) were killed than red deer (1.57–9.63/year/individual lynx), more deer were killed in winter than in summer, and lynx family groups had higher annual kill rates than adult male, single adult female and subadult female lynx. In winter the probability of a deer killed and the expected number of kills were higher outside the most protected part of the study area than inside; in summer, this probability did not differ between areas, and the expected number of kills was slightly larger inside than outside the most protected part of the study area. This indicates that the intensity of lynx predation in the unprotected part of the Bohemian Forest Ecosystem increases in winter, thus mitigation of conflicts in these areas should be included as a priority in the lynx conservation strategy.

    Teisseyre-Tornquist Zone (TTZ) corresponds to a crustal boundary between the Precambrian East European Platform (EEP) and the Palaeozoic West European Platform. Although the zone has been controlling Phanerozoic evolution of large parts of Central Europe, its course, geometry and origin are still poorly constrained. Deep reflection seismic profile POLCRUST-01, recently acquired in SE Poland, for the first time allowed a precise comparison of the Ediacaran and later tectonic patterns to the deep crustal features of the TTZ and adjacent areas. The TTZ corresponds to the subvertical Tomaszów Fault separating the Radom-Kraśnik Elevation, composed of the typical EEP crust, from the Biłgoraj-Narol Block (BNB) in the SW, with a thinned crystalline basement showing affinities to the EEP crust. The BNB is a part of the larger Caledonian Łysogóry Terrane as evidenced by its Lower Palaeozoic stratigraphy and gravity data. Thus, for the first time, the proximal Baltican affinity of this unit has been documented unambiguously. The Łysogóry Terrane is delimited from the SW by the subvertical Cieszanów Fault Zone, corresponding to the Holy Cross Suture. The adjacent Małopolska Terrane is characterized by a distinct Early Palaeozoic stratigraphy, and lower-middle crust exhibiting SW-dipping reflective packages interpreted as NE-verging thrust and shear zones of a Neoproterozoic orogen. The observations from the POLCRUST-01 profile and regional comparisons indicate that the TTZ is a major Caledonian transcurrent zone between Poland and East Romania. In central Poland, the TTZ likely forms a narrow subvertical contact between the EEP and a proximal Kuiavia Terrane, as constrained by the deep refraction seismic data. To the NW, the zone extends towards the Pomeranian part of the Caledonide fold-and-thrust belt related to the Avalonia-Baltica collision zone (Thor Suture). South-east of Poland the TTZ corresponds to the Rava Ruska Fault Zone established as a Caledonian suture

  4. Alchemical poetry in medieval and early modern Europe: a preliminary survey and synthesis. Part II - Synthesis.

    2011-03-01

    This article provides a preliminary description of medieval and early modern alchemical poetry composed in Latin and in the principal vernacular languages of western Europe. It aims to distinguish the various genres in which this poetry flourished, and to identify the most representative aspects of each cultural epoch by considering the medieval and early modern periods in turn. Such a distinction (always somewhat artificial) between two broad historical periods may be justified by the appearance of new cultural phenomena that profoundly modified the character of early modern alchemical poetry: the ever-increasing importance of the prisca theologia, the alchemical interpretation of ancient mythology, and the rise of neo-Latin humanist poetry. Although early modern alchemy was marked by the appearance of new doctrines (notably the alchemical spiritus mundi and Paracelsianism), alchemical poetry was only superficially modified by criteria of a scientific nature, which therefore appear to be of lesser importance. This study falls into two parts. Part I provides a descriptive survey of extant poetry, and in Part II the results of the survey are analysed in order to highlight such distinctive features as the function of alchemical poetry, the influence of the book market on its evolution, its doctrinal content, and the question of whether any theory of alchemical poetry ever emerged. Part II is accompanied by an index of the authors and works cited in both parts. PMID:21797075

  5. Large Scale Cooling in Tertiary Central Europe as inferred by the MBT/CBT Paleothermometer

    Earth's climate experienced dramatic changes throughout the last 65 Ma. Starting at the Paleocene/Eocene thermal maximum, the global climate underwent a gradual cooling that eventually resulted in the glaciations in the Neogene. Most reconstructions of climate variability are derived from the marine realm using global deep sea oxygen isotope curves or molecular paleotemperature proxies. In contrast, only little information on the changes of the continental climate is available, which is mainly due to a lack of continuous high resolution records and suitable quantitative temperature proxies. The MBT/CBT paleothermometer is a novel temperature proxy based on temperature-driven changes in the branched glycerol dialkyl glycerol tetraether (GDGT) content of soil-living bacteria. These changes have been demonstrated to correlate well with ambient air temperature and the MBT/CBT proxy has thus been used to reconstruct paleotemperature records of terrestrial as well as coastal marine sediments (1). In this study, we employed the MBT/CBT paleothermometer on a number of maar lake deposits that - due to their exceptional well preserved organic matter content and finely-laminated sediments - comprise excellent archives of a continental climate. The analysed lacustrine deposits were all situated in the middle European Tertiary volcanic belt and ranged in age from the Early Eocene to the Late Oligocene, allowing for the detailed reconstruction of climate evolution of the Central European continent. Calculated mean annual air temperatures (MAAT) of the Messel oil shale, deposited during the Eocene climate optimum, averaged at 25 °C. This agrees well with previous temperature estimates based on paleontological observations, suggesting a paratropical climate in Eocene Central Europe with an average air temperature of ca. 25-30 °C (2). In contrast, to the green house period of the Early Eocene, the climate of the Oligocene was significantly cooler reflected by low MAAT of 8-15

  7. Meso-Cenozoic intraplate contraction in Central and Western Europe: a unique tectonic event?

    2014-05-01

    From the British Isles to Poland, Europe experienced contractional deformation in Late Cretaceous and Paleogene time. The closest contemporaneous plate margins were the incipient Mid-Atlantic rift in the west and northwest, and the Mediterranean system of subduction zones in the south. Each of these plate margins was located more than 1000 km away from the site of deformation. This tectonic event thus represents an outstanding example of large-scale intraplate shortening and may serve as a template for comparison with modern examples. Its effects are seen in a ca. 500 km wide strip that stretches in NW-SE-direction along the Tornquist Line, a regional fault zone separating thick lithosphere of the Baltic Shield from much thinner lithosphere to the southwest. Most faults and folds also trend NW-SE, but some are linked by large N-S-striking transfer zones. In the southeast, the shortening structures are truncated by the Neogene Carpathian thrust front; their original extent is unknown. In the west, the fault zones fan out into more northerly trends in the Central North Sea and more easterly trends in the Channel area before dying out on the shelf. Late Cretaceous (ca. 90-70 Ma) shortening dominates from Poland to the North Sea, while the main shortening event in Southern Britain is of Paleogene age. Many Late Cretaceous to Paleogene structures have been conditioned by Permian or Triassic through Early Cretaceous extensional faulting, whereas some large basement uplifts and reverse faults have no demonstrable inheritance from earlier extension. The thick, mobile Zechstein salt has modified extensional and contractional structures, but both extend beyond its depositional borders. Even where thick evaporates underlie the Mesozoic sedimentary cover, the basement is typically involved in the deformation, except for localized thin-skinned imbricate thrusting and salt-cored anticlines. Different structural styles do not appear to correlate with the magnitude of shortening

    Underground storage systems are currently being used worldwide for the geological storage of natural gas (CH4), the geological disposal of CO2, in geothermal energy, or radioactive waste disposal. We introduce a complex approach to the risks posed by induced bedrock instabilities in deep geological underground storage sites. Bedrock instability owing to underground openings has been studied and discussed for many years. The Bohemian Massif in the Czech Republic (Central Europe) is geologically and tectonically complex. However, this setting is ideal for learning about the instability state of rock masses. Longterm geological and mining studies, natural and induced seismicity, radon emanations, and granite properties as potential storage sites for disposal of radioactive waste in the Czech Republic have provided useful information. In addition, the Czech Republic, with an average concentration radon of 140 Bq m-3, has the highest average radon concentrations in the world. Bedrock instabilities might emerge from microscale features, such as grain size and mineral orientation, and microfracturing. Any underground storage facility construction has to consider the stored substance and the geological settings. In the Czech Republic, granites and granitoids are the best underground storage sites. Microcrack networks and migration properties are rock specific and vary considerably. Moreover, the matrix porosity also affects the mechanical properties of the rocks. Any underground storage site has to be selected carefully. The authors suggest to study the complex set of parameters from micro to macroscale for a particular place and type of rock to ensure that the storage remains safe and stable during construction, operation, and after closure.

    Temporal patterns of immigration to the country were analysed using 668 alien species in the flora of the Czech Republic for which the dates of the first record were available (64.8% of the total number of 1031 so-called neophytes, i.e. aliens introduced after the year 1500). After a period of initial slow increase lasting to the 1840s, the accumulation of neophytes over time could be best fitted by a linear model that explained 97% of the variance. The intensity of floristic research, which varied between periods, did not significantly affect the overall increase in the number of aliens. The effect of species traits on the year of introduction was evaluated, with continent of origin, introduction type (deliberate or accidental), life history, Grime's life strategy, onset of flowering, mode of dispersal and propagule size as explanatory variables. Species of European origin and CSR strategists arrived earlier than those with other origins and strategies. Deliberately introduced species appeared earlier than accidental arrivals, and those cultivated for utilitary reasons on average arrived earlier than ornamentals. Species capable of early flowering were remarkably more prevalent among early newcomers. A separate analysis of accidentally introduced American species also identified life history as a significant predictor of immigration time, with annuals being introduced earlier than biennials and perennials. The data contribute to an understanding of a crucial stage of the invasion process that has received little attention in the literature. The model "early alien" to Central Europe is a European species with a CSR strategy deliberately brought for cultivation as a utilitary plant. Once it escaped from cultivation, its establishment in the wild was favoured by its ability to flower early and, therefore, complete the life cycle. PMID:12647111

  10. Crustal thickness in central Europe from single-station seismic noise autocorrelation analysis

    2016-04-01

    The InSight mission to Mars will place a single three-component seismometer on the planet's surface, requiring the application of single-station methods. In addition, seismicity on Mars is likely less abundant than on Earth, making it important to also use the available seismic noise. For these reasons different approaches of seismic noise autocorrelation have been tested with broadband three-component datasets from 12 stations across central Europe. These stations cover varying Moho depths of ca. 25-50 km depth. With the help of the autocorrelations, reflected body waves are extracted in order to estimate the crustal thickness at each station. This is of special relevance for Mars, where average crustal thickness is uncertain by a factor of two. The different approaches used are waterlevel normalized autocorrelation, with and without application of a short-term and long-term average filter to the spectrum of the data prior to autocorrelation, and phase autocorrelation. These approaches are compared and analyzed. Estimates for the Moho depths are made from the lag times of the reflected P-waves and compared to available Moho depth values at the stations. Due to the availability of three-component data these estimates can be cross-validated and in some cases not only P-wave reflections, but also possible S-wave and multiple reflections can be identified. The estimates compare well with the general trend of Moho depth expected for these stations. The consistency of results is further investigated by comparing different stations of the GERES array (aperture 2 km), which also allows to examine results for closely located broad-band and short-period stations side by side.

  11. Low Usutu virus seroprevalence in four zoological gardens in central Europe

    PubMed Central

    2013-01-01

    Background Usutu virus (USUV), a mosquito-borne flavivirus of the Japanese encephalitis virus antigenic group, caused bird die-offs in Austria, Hungary and Switzerland between 2001 and 2009. While the zoological gardens of Vienna and Zurich recorded USUV-associated mortality in different species of birds during this period, incidences in Budapest were limited to areas outside the zoo, and in the greater Basel area avian mortality due to USUV infection was not observed at all. The objectives of this investigation were to gain insight into USUV infection dynamics in captive birds in zoos with varying degrees of virus exposure and to study differences in susceptibility to USUV of different species of birds. Results 372 bird sera were collected between October 2006 and August 2007. The samples were tested in parallel by hemagglutination inhibition (HI) and 90% plaque reduction neutralization tests (PRNT-90). 8.75%, 5.3% and 6.59% of birds in the zoos of Vienna, Zurich and Basel, respectively, showed USUV-specific antibodies by PRNT-90. No antibodies to USUV were detected in birds of the Budapest zoo. The order Strigiformes (owls) exhibited the highest USUV-seroprevalence, compared to other orders of birds. Conclusions USUV seems not to pose an imminent threat to zoo bird populations in central Europe at the moment. Depending on a variety of especially environmental factors, however, this may change at any time in the (near) future, as experienced with West Nile virus (WNV). It is therefore strongly suggested to continue with combined WNV and USUV surveillance activities in affected areas. PMID:23919825

    The ongoing global financial crisis, which began in 2007, has drawn attention to the effect of declining economic conditions on public health. A quantitative analysis of previous events can offer insights into the potential health effects of economic decline. In the early 1990s, widespread recession across Central and Eastern Europe accompanied the collapse of the Soviet Union. At the same time, despite previously falling tuberculosis (TB) incidence in most countries, there was an upsurge of TB cases and deaths throughout the region. Here, we study the quantitative relationship between the lost economic productivity and excess TB cases and mortality. We use the data of the World Health Organization for TB notifications and deaths from 1980 to 2006, and World Bank data for gross domestic product. Comparing 15 countries for which sufficient data exist, we find strong linear associations between the lost economic productivity over the period of recession for each country and excess numbers of TB cases (r(2) = 0.94, p < 0.001) and deaths (r(2) = 0.94, p < 0.001) over the same period. If TB epidemiology and control are linked to economies in 2009 as they were in 1991 then the Baltic states, particularly Latvia, are now vulnerable to another upturn in TB cases and deaths. These projections are in accordance with emerging data on drug consumption, which indicate that these countries have undergone the greatest reductions since the beginning of 2008. We recommend close surveillance and monitoring during the current recession, especially in the Baltic states. PMID:20427332

    Following flooding in central Europe in June 2013, we have produced a flood footprint describing the maximum extent and depth of flooding. Rapid damage estimation for a flood event such as this is useful for the re/insurance industry, in which companies need to estimate the impact of flooding on their business. An early understanding of the geographical scope and severity of an event allows claims adjusters to be deployed effectively and an estimation of the potential loss ensures adequate release of funds to pay for claims. Following reports of heavy rainfall in the headwaters of the Isar, Saale, Inn, and Elbe during the first week of June 2013, we began monitoring the http://www.hochwasserzentralen.de/ website and extracted peak flow for the affected gauges. Using extreme value statistical analysis of the historic flow records, we assessed the return period of the flow generated by the 2013 event for each gauged location. This return period was then interpolated along each river reach taking into consideration catchment characteristics. Then, using previously developed Germany design hazard maps containing information on the extent and depth of flooding associated with a range of return periods at 10m resolution, we pieced together a flood footprint along the course of the affected rivers and tributaries. With much of the Elbe/Danube heavily defended and regulated, we then undertook a detailed manual exercise to account for defences and any breach locations. Here georeferenced ground / aerial photographs and satellite footprint maps produced by the German Aerospace Centre (DLR) and available through the media were used to establish the integrity of defences and to validate our flood footprint. The resulting footprint was licensed by a number of companies within the re/insurance sector and is being used by academic partners for further research into damage assessment.

    Aerosols are a major component of the Earth's atmosphere and have substantial impact on the Earth's radiation budget and on the hydrological cycle. Biomass burning smoke is one important component with respect of global climate warming as it is an important source of black carbon, which is a key player in atmospheric heating. As biomass burning smoke layers are often transported over long distances they cannot be considered as local events only but have a global effect. During transport the smoke particles are affected by aging and mixing processes. Thus their microphysical and optical properties change and, as a consequence their effect on the Earth's radiation budget. However, the influence of aging and mixing processes on the particle microphysical and optical properties is still only poorly understood. To improve our knowledge, studies of transport conditions together with measurements of the horizontal and vertical distribution the smoke layers as well as of their microphysical and optical properties are crucial. We present a case study of long-range transported Canadian biomass burning smoke to Central Europe in summer 2013. The smoke layer is characterized by multi-wavelength lidar measurements over Maisach and by continuous Ceilometer measurements over Munich, Germany. Multi-wavelength lidar measurements are an important tool for the characterization of aerosols, as they provide vertically resolved information of their optical properties which serve as input parameters for the determination of microphysical properties of the aerosol layers. Additionally, airborne in-situ measurements of size distribution and black carbon mass concentration onboard the DLR research aircraft Falcon are presented. The source regions and transport conditions are studied using a combination of satellite measurements and model simulations.

    The earthworm activity is generally recognized as an important factor changing the intrinsic heterogeneity of soil environment including the microbial constituents. In central Europe, about 40% of earthworm species are endemic to this region, some of them dominating forest and grassland ecosystems and playing a keystone role in the soil food-web. However, current knowledge about the effects of earthworms on soil microorganisms derives from studies on a few peregrine species only. Our study brought a view on the microbial component of the steppe soil affected by the activity of Allolobophora hrabei, an endemic earthworm fragmentary distributed in the border regions of the Czech Republic, Austria, Slovakia and Hungary. The study was carried out in three steppe fragments, where A. hrabei represented a key earthworm species. Comprehensive approach based on bio-indicating quantitative and qualitative options of extended phospholipid fatty acids analysis (PLFA) of bulk soil, drilosphere sensu lato and casts was used on data from two-years monitoring. In situ observation was completed by detailed observation of the casts-microbiota succession under controlled laboratory conditions. Our results showed that A. hrabei significantly affected soil microorganisms mainly via its extremely high casting activity. The doubled biomass, new qualitative composition, better growth and nutritional status of microbial community together with significantly higher availability of phosphorus and organic carbon in casts in contrast to bulk soil confirmed beneficial impact of A. hrabei on the soil environment. A. hrabei has burrowed up to more than one metre depths and produced more than 3 kg . m-2 of casts per year.

  16. The supply of alcoholic beverages in transitional conditions: the case of Central and Eastern Europe.

    2000-12-01

    Three periods are distinguished and applied to describe the dynamics of changes in the system of supply of alcoholic beverages in Central and Eastern Europe since 1980. The distinction of these three periods is based on changes in the regulation of the supply. The period of the old regulation ended in most countries around the 1990s. A deregulation took place in the early 1990s. The first steps toward a reregulation were visible in attempts to create a new order in the alcohol market in the last years of the 1990s. The analysis builds mainly on developments in Poland and Russia, with more scattered information from other countries. In each period the role of different actors (the state, the enterprises, organized crime, civil organizations and individuals), different interests (economic development, state finances, political order, public order, public health and various symbolic interests) and different public measures to regulate the supply (licensing, taxation and preventive actions and treatment) are considered. The analysis shows how the state lost its dominant position to private firms and is slowly regaining it again, how interest in state finances, overall economic development and later in profit-making dominate all three periods, and how the old system of regulations was ruined, to become rebuilt in very small steps with many conflicts and complications. Public health interests and also civil society interests were weak in comparison with economic interests. From the public health perspective, changes in the supply system have had significant consequences, but a more comprehensive regulation of supply does not necessarily lead to diminished alcohol-related harm.

  17. Dust transport and palaeoclimate during the Oldest Dryas in Central Europe - implications from varves (Lake Constance)

    1992-10-01

    This paper evaluates evidence for seasonal loess deposits in peri-Alpine Lake Constance at the end of the last Glacial (Oldest Dryas chronozone). The sedimentology of laminated couplets comprising yellow and grey silts evaluates the couplets as varves comprising alternations of loess and glacial silt and clay. The laminae, less than 1 mm thick, include from bottom to top: (1) a matrix of well-sorted, non-graded fine yellow silt with sand-size intraclasts, (2) coarsening-upward grey silt with a cap of fining-upward silt to clay. This is typical and reflects summer and winter deposits (silt and clay, respectively). The authors propose that the lack of grading and the matrix supported fabric is indicative of aeolian transport and interpret the yellow laminae as loess deposits. Volcanic glass intraclasts in the loess layers are probably derived from volcanic terrain to the west of the lake, indicating an easterly palaeowind direction. Deposition of loess in the lake occurred regularly at the beginning of each annual cycle, suggesting the palaeowinds were associated with winter and/or spring conditions. Two transport scenarios are suggested to explain the sand grains scattered in this deep-water lacustrine record. 1. The grains may have been transported as bedload over the annual winter ice-cover of the lake under moderate wind strengths, frozen into the ice, and released for deposition during spring melt. 2. The sand grains were blown directly out onto the lake water by very strong winds during spring. The first scenario is contrary to the general view that loess was transported during summer, and that loess deposits thus reflect summer conditions only. Loess input to the lake shows a transitional decrease after ca. 14.3 kyr BP and cessation at ca. 14 kyr BP, probably as a result of a change of wind behaviour, increased humidity and/or vegetational changes during the Oldest Dryas in central Europe. 62 refs., 8 figs.

    In 2003, Central Europe experienced the warmest summer on record combined with unusually low precipitation. We studied plant water relations and phenology in a 100-year- old mixed deciduous forest on a slope (no ground water table) near Basel using the Swiss Canopy Crane (SCC). The drought lasted from early June to mid September. We studied five deciduous tree species; half of the individuals were exposed to elevated CO(2) concentration ([CO(2)]) (530 ppm) using a free-air, atmospheric CO(2)-enrichment system. In late July, after the first eight weeks of drought, mean predawn leaf water potential about 30 m above ground was -0.9 MPa across all trees, dropping to a mean of -1.5 MPa in mid-August when the top 1 m of the soil profile had no plant accessible moisture. Mean stomatal conductance and rates of maximum net photosynthesis decreased considerably in mid-August across all species. However, daily peak values of sap flow remained surprisingly constant over the whole period in Quercus petraea (Matt.) Liebl., and decreased to only about half of the early summer maxima in Fagus sylvatica L. and Carpinus betulus L. (stomatal down- regulation of flux). Although we detected no differences in most parameters between CO(2)-treated and control trees, predawn leaf water potential tended to be less negative in trees exposed to elevated [CO(2)]. Leaf longevity was greater in 2003 compared with the previous years, but the seasonal increase in stem basal area reached only about 75% of that in previous years. Our data suggest that the investigated tree species, particularly Q. petraea, did not experience severe water stress. However, an increased frequency of such exceptionally dry summers may have a more serious impact than a single event and would give Q. petraea a competitive advantage in the long run.

    The bilinear receptor model positive matrix factorization (PMF) was used to apportion particulate matter with an aerodynamic diameter of 1-10 microm (PM1-10) sources in a village, Brezno, situated in an industrial region of northern Bohemia in Central Europe. The receptor model analyzed the data sets of 90- and 60-min integrations of PM1-10 mass concentrations and elemental composition for 27 elements. The 14-day sampling campaigns were conducted in the village in summer 2008 and winter 2010. Also, to ensure seasonal and regional representativeness of the data sets recorded in the village, the spatial-temporal variability of the 24-hr PM10 and PM1-10 within 2008-2010 in winter and summer across the multiple sites was evaluated. There were statistically significant interseasonal differences of the 24-hr PM data, but not intrasummer or intrawinter differences of the 24-hr PM1-10 data across the multiple sites. PMF resolved seven sources of PM1-10. They were high-temperature coal combustion; combustion in local heating boilers; marine aerosol; mineral dust; primary biological/wood burning; road dust, car brakes; and gypsum. The main summer factors were assigned to mineral dust (38.2%) and primary biological/wood burning (33.1%). In winter, combustion factors dominated (80%) contribution to PM1-10. The conditional probability function (CPF) helped to identified local sources of PM1-10. The source of marine aerosol from the North Sea and English Channel was indicated by the Hybrid Single Particle Lagrangian Integrated Trajectory Model (HYSPLIT).

    Thunderstorms in the territories of the Czech Republic and neighbouring countries are almost exclusively the only phenomena occurring in the warm season. In the cold half of the year, from October to March, an average incidence of thunderstorms is only 2%, with the least occurrence being recorded in January. Yet, winter thunderstorms are dangerous particularly for air traffic because during them, the cloud base is rapidly falling down and visibility is suddenly worsening due to heavy snowfall. Notwithstanding these facts, the issue of their occurrence in the central European space has been paid little attention so far. Long years of study into historical weather extremes in the territory of the Czech Republic revealed over 10 chronicle entries on the occurrence of winter thunderstorms in the period between November and February from the 16th to the beginning of the 20th centuries. The irregular phenomenon was even devoted three occasional prints in central Europe in the second half of the 16th century, two of which were issued in Germany. Fires caused by winter thunderstorms were no sporadic cases. The occurrence of thunderstorms in winter was apparently associated with the passage of pronounced cold fronts. This can be documented on cases from the end of December 1555 when heavy thunderstorms and consequent fires were recorded within a short period of time in Holland, Germany and in Czech lands. It is assumed that the situation in 1627 was similar when a winter thunderstorm was recorded in Prague and in Holešov, southeastern Moravia on 28 December. In February 1581, a thunderstorm in Prague became one of three unusual events publicized by the local occasional newspaper. The beginning of modern studies into winter thunderstorms dates back to the 1960s with the use of lightning flash counters and later also with the use of systems for large-scale lightning flash detection and localization. However, more comprehensive meteorological and climatological assessments of

    The multi-risk approach is a relatively new field and its definition includes the need to consider multiple hazards and vulnerabilities in their interdependency (Selva, 2013) and the current multi-hazards disasters, such as the 2011 Tohoku earthquake, tsunami and nuclear catastrophe, showed the need for a multi-risk approach in hazard mitigation and management. Our knowledge about multi-risk assessment, including studies from different scientific disciplines and developed assessment tools, is constantly growing (White et al., 2001). However, the link between scientific knowledge, its implementation and the results in terms of improved governance and decision-making have gained significantly less attention (IRGC, 2005; Kappes et al., 2012), even though the interest to risk governance, in general, has increased significantly during the last years (Verweiy and Thompson, 2006). Therefore, the key research question is how risk assessment is implemented and what is the potential for the implementation of a multi-risk approach in different governance systems across Europe. More precisely, how do the characteristics of risk governance, such as the degree of centralization versus decentralization, influence the implementation of a multi-risk approach. The methodology of this research includes comparative case study analysis of top-down and bottom-up interactions in governance in the city of Naples, (Italy), where the institutional landscape is marked by significant autonomy of Italian regions in decision-making processes for assessing the majority of natural risks, excluding volcanic, and in Guadeloupe, French West Indies, an overseas department of France, where the decision-making process is marked by greater centralization in decision making associated with a well established state governance within regions, delegated to the prefect and decentralised services of central ministries.

    As reflected in δ18O values in ice cores, the North Atlantic area experienced a series of abrupt, dramatic climatic fluctuations over the last glacial during which oceanic and atmospheric conditions alternated between full glacial (stadial) and relatively mild (interstadial) conditions [1,2]. Beyond the δ18O profiles, calcium ion concentration data (hereafter [Ca2+]) also exhibit particularly clear stadial/interstadial contrasts [3]. The Ca2+/dust concentration records are considered as a proxy for the amount of terrestrial dust reaching the ice sheet [4] and/or changing dust storm activity in the source areas around the Northern Hemisphere, mainly in East Asia [5,6]. The mode of the dust size distributions is thought to reflect transit times during transport, with larger modes indicating shorter transit times and transport routes, i.e. changed atmospheric circulation patterns [5]. However, based on clay mineralogy and Sr-Nd isotopic compositions of loess sediments Újvári, et al. [7] suggested that Central European dust cannot be excluded as a potential source of Greenland dust. As such, it is vital to analyze dust deposition in the key dust depocentres of Eastern Europe. As a record of Carpathian Basin dust source activity, we therefore studied loess sedimentation and grain size changes in the Dunaszekcsö loess sequence in Southern Hungary. For this record, we developed the highest resolution geochronological dataset for European loess based on 61 AMS 14C dates from molluscs and charcoal fragments. This allowed us to establish a uniquely high precision Bayesian age-depth model, with the mean 95% confidence ranges that vary between 119 and 798 yr. Sedimentation rates (SR) calculated from the age-depth model vary between 0.36-1.7 mm yr‑1 and the estimated bulk dust mass accumulation rates (MAR) range from 551 to 2525 g m‑2 yr‑1. Both the SR and MAR display millennial/sub-millennial scale variations, visible uniquely due to the high precision dating

    The 2015 summer was the warmest summer ever observed in Central Europe according to many characteristics, including the overall severity of heat waves. We assess how unusual this summer was by i) comparing the seasonal temperature anomalies and severity of heat waves against long-term temperature records at Central European stations, ii) evaluating its temperature characteristics at the continental scale against hot summers and major heat waves affecting Europe recently (including the 2003 western-European heat waves and the 2010 Russian heat waves), and iii) identifying time slices in climate change scenarios for the 21st century in which similar events are projected to occur over Central Europe at least once per decade. In the last point, we make use of a large ensemble of RCM simulations from CORDEX and ENSEMBLES projects and critically evaluate their ability to simulate events such as the 2015 summer (in terms of both seasonal temperature anomalies and heat waves, including their spatial extent). We examine also how results for the climate change scenarios depend on radiative forcing and driving global models.

  7. Reforming sanitary-epidemiological service in Central and Eastern Europe and the former Soviet Union: an exploratory study

    2010-01-01

    Background Public health services in the Soviet Union and its satellite states in Central and Eastern Europe were delivered through centrally planned and managed networks of sanitary-epidemiological (san-epid) facilities. Many countries sought to reform this service following the political transition in the 1990s. In this paper we describe the major themes within these reforms. Methods A review of literature was conducted. A conceptual framework was developed to guide the review, which focused on the two traditional core public health functions of the san-epid system: communicable disease surveillance, prevention and control and environmental health. The review included twenty-two former communist countries in the former Soviet Union (fSU) and in Central and Eastern Europe (CEE). Results The countries studied fall into two broad groups. Reforms were more extensive in the CEE countries than in the fSU. The CEE countries have moved away from the former centrally managed san-epid system, adopting a variety of models of decentralization. The reformed systems remain mainly funded centrally level, but in some countries there are contributions by local government. In almost all countries, epidemiological surveillance and environmental monitoring remained together under a single organizational umbrella but in a few responsibilities for environmental health have been divided among different ministries. Conclusions Progress in reform of public health services has varied considerably. There is considerable scope to learn from the differing experiences but also a need for rigorous evaluation of how public health functions are provided. PMID:20663198

    Molecular phylogeography suggests that Micromys minutus, the sole extant species of the genus, colonized its extensive range quite recently, during the Late Pleistocene-Holocene period. Rich Pliocene and Pleistocene fossil records both from Europe and China suggest rather continuous and gradual in situ phenotype rearrangements from the Pliocene to the Recent periods. To elucidate the discrepancy we reexamined a considerable part of the European fossil record of the genus (14 sites from MN15 to Q3, 0.4-4.2 Ma, including the type series of M. preaminutus from MN15 Csarnóta 2), analyzed them with the aid of detailed morphometric comparisons, and concluded that: (a) The European Pliocene form, M. praeminutus, differs significantly from the extant species; (b) it exhibits a broad phenotypic variation covering the presumptive diagnostic characters of MN16 M. caesaris; (c) despite having smaller dimensions, the Early and Middle Pleistocene forms (MN17-Q3, 2.6-0.4 Ma) seem to be closer to M. praeminutus than to the extant species; (d) the extinction of M. praeminutus during Q3 and the re-occupation of its niche by the recent expansion of M. minutus from E-European-C Asiatic sources (suggested by phylogeographic hypotheses) cannot be excluded. Discussing interpretations of the phylogenetic past of the genus we emphasize the distinct history of the West Palearctic clade (Late Miocene-Early Pleistocene) terminating with M. praeminutus and the East Asiatic clade (chalceus, tedfordi, minutus), and the possible identity of the Western clade with the Late Miocene genus Parapodemus.

    2014-01-01

    Humeral morphology has been shown to reflect, in part, habitual manipulative behaviors in humans. Among Central European agricultural populations, long-term social change, increasing task specialization, and technological innovation all had the potential to impact patterns of habitual activity and upper limb asymmetry. However, systematic temporal change in the skeletal morphology of agricultural populations in this region has not been well-characterized. This study investigates diachronic patterns in humeral biomechanical properties and lengths among 174 adult Central European agriculturalists through the first ∼ 5400 years of farming in the region. Greater asymmetry in biomechanical properties was expected to accompany the introduction of metallurgy, particularly in males, while upper limb loading patterns were expected to be more similar between the Bronze and Iron Ages. Results revealed a divergence in the lateralization of upper limb biomechanical properties by sex between the Early/Middle Neolithic and Early/Middle Bronze Age. Neolithic females had significantly more variable properties than males in both humeri, while Bronze Age female properties became homogeneous and very symmetrical relative to the right-biased lateralization of contemporaneous males. The Bronze Age to Iron Age transition was associated with morphological change among females, with a significant increase in right-biased asymmetry and a concomitant reduction in sexual dimorphism. Relative to biomechanical properties, humeral length variation and asymmetry were low though some significant sexual dimorphism and temporal change was found. It was among females that the lateralization of humeral biomechanical properties, and variation within them, changed most profoundly through time. This suggests that the introduction of the ard and plow, metallurgical innovation, task specialization, and socioeconomic change through ∼ 5400 years of agriculture impacted upper limb loading in Central

    The main goals of the research are (i) to compare weather pattern classification methods for Central Europe (COST733 domain 07 covering 43-58°N, 3-26°E) using observed and simulated present climate (1961-1990), and (ii) to analyze the climate change effects on weather patterns for the same region using different classification methods. The observed climate is represented by the ECMWF ERA40 datasets, and the simulation experiments were accomplished for future climate conditions (2071-2100) using two emission scenarios (A2 and B2) in the frame of the EU-project PRUDENCE (Prediction of Regional scenarios and Uncertainties for Defining EuropeaN Climate change risks and Effects). High resolution (50 km × 50 km) simulated daily values of meteorological variables (mean sea level pressure, temperature, precipitation) have been obtained from the regional climate model (RCM) outputs of the Danish Meteorological Institute (DMI). DMI used the HIRHAM4 RCM (developed jointly by DMI and the Max-Planck Institute in Hamburg), for which the boundary conditions were provided by the HadAM3H/HadCM3 global climate model of the UK Met Office. For the weather pattern classification we use the COST733 classification software (version 0.19-17). The 12 available classification methods (grouped into (i) optimization algorithms, (ii) leader algorithms, (iii) PCA based methods, and (iv) threshold based methods) are applied to the ERA40 daily mean sea level pressure database for 1961-1990 using 9, 18, and 27 weather pattern types.

    Measurements of the vertical distribution of atmospheric mercury (Hg) are rare, because airborne measurements are expensive and labour intensive. Consequently, only a few vertical Hg profile measurements have been reported since the 1970s. Besides the CARIBIC passenger aircraft observations, the latest vertical profile over Europe was measured in 1996. Within the Global Mercury Observation System (GMOS) project four vertical profiles were taken on board research aircraft (CASA-212) in August 2013 in background air over different locations in Slovenia and Germany. Each vertical profile consists of at least seven 5 min horizontal flight sections from 500 m above ground to 3000 m a.s.l. Gaseous elemental mercury (GEM) was measured with a Tekran 2537X analyser and a Lumex RA-915-AM. Total gaseous mercury (TGM) was measured using a Tekran 2537B analyser and gaseous oxidized mercury (GOM) was sampled onto 8 denuders for post flight analysis (one for each profile, three during the transfer flights, and two blanks). In addition to the mercury measurements, SO2, CO, O3, NO, NO2, as well as basic meteorological parameters (pressure, temperature, relative humidity) have been measured. Additional ground based speciated mercury measurements at the GMOS master site in Waldhof (Germany) were used to extend the profile to the ground. No vertical gradient was found inside the well mixed boundary layer (variation by less than 0.1 ng m-3) at different sites with GEM varying from location to location between 1.4 and 1.6 ng m-3 (STP; standard conditions: p = 1013.25 hPa, T = 273.15 K). At all locations GEM dropped to 1.3 ng m-3 (STP) when entering the free troposphere and remained constant at higher altitudes. The combination of the vertical profile, measured on 21 August 2013, over Leipzig (Germany) with the CARIBIC measurements during ascent and descent to Frankfurt airport (Germany) at approximately the same time provide a unique central European vertical profile from inside the

The model simulation was evaluated using measurements of equivalent soot carbon, absorption coefficients and particle number concentrations at 7 sites within the German Ultrafine Aerosol Network, PM10 mass concentrations from the dense measurement network of the German Federal Environmental Agency at 392 monitoring stations, and aerosol optical depth from MODIS and AERONET. A distinct time period (25 March to 10 April 2009) was chosen, during which the clean marine air mass prevailed in the first week and afterwards the polluted continental air mass mainly from south-east dominated with elevated daily average BC concentration up to 4 μg m-3. The simulated PM10 mass concentration, aerosol number concentration and optical depth were in a good agreement with the observations, while the modelled BC mass concentrations were found to be a factor of 2 lower than the observations. Together with backtrajectories, detailed model bias analyses suggested that the current BC emission in countries to the east and south of Germany might be underestimated by a factor of 5, at least for the simulation period. Running the model with upscaled BC emissions in these regions led to a smaller model bias and a better correlation between model and measurement. On the contrary, the particle absorption coefficient was positively biased by about 20% even when the BC mass concentration was underestimated by around 50%. This indicates that the internal mixture treatment of BC in the WRF-Chem optical calculation is unrealistic in our case, which over amplifies

    To check for compliance with the reduction targets defined under the Kyoto Protocol, each participating country has to report its greenhouse gas emissions to the UNFCCC (United Nations Framework Convention on Climate Change). These emissions are calculated using a bottom-up approach, by combining categories of compound use and specific activity (release) functions. The uncertainties of these estimates are not well defined, thereby making an independent validation of the reported emissions highly desirable. Top-down estimates based on atmospheric concentration measurements and using a reference species as a priori information are a promising method for independent emission estimates. For this purpose, atmospheric Radon (222-Rn) is very well suited due to its exactly known radioactive decay lifetime of 5.5 days and its homogeneous release over soil with comparatively small spatial and temporal variability. In the present study, concentration measurements of halogenated greenhouse gases such as hydrofluorocarbons (HFC), perfluorocarbons (PFC) and SF6 at the remote sites Jungfraujoch (Switzerland) and Mace Head (Ireland) were combined with backward calculations of the Lagrangian Particle dispersion model FLEXPART to derive emission rates over Central Europe. The ability of FLEXPART to simulate the origin of air masses arriving at the receptor point was checked using 222-Rn measurements in combination with the flux map recently developed by Szegvary et al. (2007), and analysis was restricted to episodes where FLEXPART successfully reproduced the observed concentration pattern of 222-Rn. This procedure not only removes all measurements where the flow regime of air masses is uncertain and source attribution of emissions is therefore difficult, but also allows to correct for potential model uncertainties originating e.g. from the complex topography not resolved by the model. The top-down estimations derived in this study generally agree well with the bottom-up estimates

    for various purposes including calculation of actual height and generation of ionograms. In this study, the performance of electron density reconstruction algorithm of IONOLAB group and standard electron density profile algorithms of ionosondes are compared with IONOLAB-RAY wave propagation simulation in near vertical incidence. The electron density reconstruction and parameter extraction algorithms of ionosondes are validated with the IONOLAB-RAY results both for quiet anddisturbed ionospheric states in Central Europe using ionosonde stations such as Pruhonice and Juliusruh . It is observed that IONOLAB ionosonde parameter extraction and electron density reconstruction algorithm performs significantly better compared to standard algorithms especially for disturbed ionospheric conditions. IONOLAB-RAY provides an efficient and reliable tool to investigate and validate ionosonde electron density reconstruction algorithms, especially in determination of reflection height (true height) of signals and critical parameters of ionosphere. This study is supported by TUBITAK 114E541, 115E915 and Joint TUBITAK 114E092 and AS CR 14/001 projects.

    The knowledge of the vertical distribution of atmospheric mercury (Hg) plays an important role in determining the transport and cycling of mercury. However, measurements of the vertical distribution are rare, because airborne measurements are expensive and labour intensive. Consequently, only a few vertical Hg profile measurements have been reported since the 1970s. Besides the Civil Aircraft for the Regular Investigation of the atmosphere Based on an Instrument Container (CARIBIC) observations, the latest vertical profile over Europe was measured in 1996. Within the Global Mercury Observation System (GMOS) project, four vertical profiles were taken on board research aircraft (CASA-212) in August 2013 in background air over different locations in Slovenia and Germany. Each vertical profile consists of at least seven 5 min horizontal flight sections from 500 m above ground to 3000 m a.s.l. Gaseous elemental mercury (GEM) and total gaseous mercury (TGM) were measured with Tekran 2537X and Tekran 2537B analysers. In addition to the mercury measurements, SO2, CO, O3, NO, and NO2, basic meteorological parameters (pressure, temperature, relative humidity) have been measured. Additional ground-based mercury measurements at the GMOS master site in Waldhof, Germany and measurements onboard the CARIBIC passenger aircraft were used to extend the profile to the ground and upper troposphere respectively. No vertical gradient was found inside the well-mixed boundary layer (variation of less than 0.1 ng m-3) at different sites, with GEM varying from location to location between 1.4 and 1.6 ng m-3 (standard temperature and pressure, STP: T = 273.15 K, p = 1013.25 hPa). At all locations GEM dropped to 1.3 ng m-3 (STP) when entering the free troposphere and remained constant at higher altitudes. The combination of the vertical profile, measured on 21 August 2013 over Leipzig, Germany, with the CARIBIC measurements during ascent and descent to Frankfurt Airport, Germany, taken at

    To bridge the resolution gap between the outputs of global climate models (GCMs) and finer-scale data needed for studies of the climate change impacts, two approaches are widely used: dynamical downscaling, based on application of regional climate models (RCMs) embedded into the domain of the GCM simulation, and statistical downscaling (SDS), using empirical transfer functions between the large-scale data generated by the GCM and local measurements. In our contribution, we compare the performance of different variants of both techniques for the region of Central Europe. The dynamical downscaling is represented by the outputs of two regional models run in the 10 km horizontal grid, ALADIN-CLIMATE/CZ (co-developed by the Czech Hydrometeorological Institute and Meteo-France) and RegCM3 (developed by the Abdus Salam Centre for Theoretical Physics). The applied statistical methods were based on multiple linear regression, as well as on several of its nonlinear alternatives, including techniques employing artificial neural networks. Validation of the downscaling outputs was carried out using measured data, gathered from weather stations in the Czech Republic, Slovakia, Austria and Hungary for the end of the 20th century; series of daily values of maximum and minimum temperature, precipitation and relative humidity were analyzed. None of the regional models or statistical downscaling techniques could be identified as the universally best one. For instance, while most statistical methods misrepresented the shape of the statistical distribution of the target variables (especially in the more challenging cases such as estimation of daily precipitation), RCM-generated data often suffered from severe biases. It is also shown that further enhancement of the simulated fields of climate variables can be achieved through a combination of dynamical downscaling and statistical postprocessing. This can not only be used to reduce biases and other systematic flaws in the generated time

    Drought and heat waves during summer in mid-latitudes are a serious threat to human health and agriculture and have negative impacts on the infrastructure, such as problems in energy supply. The appearance of such extreme events is expected to increase with the progress of global warming. A better understanding of the development of extremely hot and dry summers and the identification of possible precursors could help improve existing seasonal forecasts in this regard, and could possibly lead to the development of early warning methods. The development of extremely hot and dry summer seasons in central Europe is attributed to a combined effect of the dominance of anticyclonic weather regimes and soil moisture-atmosphere interactions. The atmospheric circulation largely determines the amount of solar irradiation and the amount of precipitation in an area. These two variables are themselves major factors controlling the soil moisture. Thus, solar irradiation and precipitation are used as proxies to analyse extreme sunny and dry late winter/spring and summer seasons for the period 1958-2011 in Germany and adjacent areas. For this purpose, solar irradiation data from the European Center for Medium Range Weather Forecast 40-yr and interim re-analysis dataset, as well as remote sensing data are used. Precipitation data are taken from the Global Precipitation Climatology Project. To analyse the atmospheric circulation geopotential data at 850 hPa are also taken from the European Center for Medium Range Weather Forecast 40-yr and interim re-analysis datasets. For the years in which extreme summers in terms of high solar irradiation and low precipitation are identified, the previous late winter/spring conditions of solar irradiation and precipitation in Germany and adjacent areas are analysed. Results show that if the El Niño-Southern Oscillation (ENSO) is not very intensely developed, extremely high solar irradiation amounts, together with extremely low precipitation

    In the Lower Rhine Embayment (LRE), as in other parts of Central Europe, several main periods of colluvial deposition (mainly Metal Ages, Roman time, Medieval time) and four main periods of alluvial and overbank deposition in the floodplains (Early Holocene, Metal Ages, partially Roman time, Medieval, Early Modern time) can be divided. The summary of colluvial sedimentation can be shown by using interdisciplinary methods, consisting of sedimentological, geochemical and archaeological methods. This allowed reconstructing a detailed land-use history. To clarify the origin of the colluvial deposits loess-sequences also have been studied geochemically and were compared to loess- and loess-like deposits from adjacent areas, such as the Northern Eifel Mountains or the Middle Rhine. The results clearly show that only the combination of methods of natural sciences and the humanities allow optimal processing of these complex findings. To sum up these results the following cycles cause by human activities can be found in the LRE: 8 periods with soil formation (P = pedogenesis), followed by a phase with mainly stable land surfaces but some rill / gully erosion (R) and succeeded by intensive erosion and colluviation (E) caused by mainly sheet floods in an more open landscape. Especially during the Metal Ages and High Middle Ages erosion is clearly detectable. In the woodlands strong deforestation took place especially due to the production of charcoal and firewood as well as grazing activities. In addition, the development of mining and related industries in the 15th to 16th centuries and further increase in 19th century produced a strong contamination of floodplain deposits. Different periods of an increasing grassland since Medieval time cause by socio-economic effects that results in a reduction of soil erosion can be distinguished.

    The genetic composition of the medieval populations of Central Europe has been poorly investigated to date. In particular, the region of modern-day Slovakia is a blank spot in archaeogenetic research. This paper reports the study of mitochondrial DNA (mtDNA) in ancient samples from the 9th-12th centuries originating from the cemeteries discovered in Nitra-Šindolka and Čakajovce, located in western Slovakia (Central Europe). This geographical region is interesting to study because its medieval multi-ethnic population lived in the so-called contact zone of the territory of the Great Moravian and later Hungarian state formations. We described 16 different mtDNA haplotypes in 19 individuals, which belong to the most widespread European mtDNA haplogroups: H, J, T, U and R0. Using comparative statistical and population genetic analyses, we showed the differentiation of the European gene pool in the medieval period. We also demonstrated the heterogeneous genetic characteristics of the investigated population and its affinity to the populations of modern Europe.

    Precise estimates of mean annual temperature (MAT) for when Neanderthals occupied Central Europe are critical for understanding the role that climatic and associated environmental factors played in Neanderthal migrations and in their ultimate extinction. Neanderthals were continuously present in the relatively warm regions of southern and Western Europe in the Pleistocene but only temporarily settled Central Europe (CE), presumably because of its colder and less hospitable climate. Here, we present a new approach for more spatially and temporally accurate estimation of palaeotemperatures based on the stable oxygen isotope composition of phosphates extracted from animal teeth found at sites linked directly to concurrent Neanderthal occupation. We provide evidence that Neanderthals migrated along the Odra Valley of CE during warmer periods throughout the Upper Pleistocene. The MATs during these migrations were about 6.8 °C for the warm phase of Oxygen Isotope Stage OIS 5a-d (prior to the OIS4 cold event) at ˜115-74,000 yr BP and about 6.3 °C during the early OIS 3 warm phase ˜59-41,000 yr BP. Our results show that temperatures during these phases peaked 2-4 °C above longer term estimates from ice cores and pollen records. We argue that our approach can provide valuable insights into evaluating the role of climate in human migration patterns in the Pleistocene.

    The western part of the Iberian Peninsula (Iberian Massif) is the best exposed fragment of the Variscan orogen in Europe. Its southern half was generated by an oblique collision between three continental terranes belonging to the margins of Laurassia (Avalonia) - the South Portuguese Zone- and Godwana - the Ossa Morena Zone (OMZ) and the Central Iberian Zone (CIZ). The boundaries between them are considered to be sutures. A 210 km long magnetotelluric profile across the eastern part of the Central Iberian Zone is presented. The profile crosses the boundary between the Ossa Morena and Central Iberian zones and spans up to the Tajo basin, crossing the Sierra de Alcudia and the Toledo Mountains. The main structures investigated are: the Los Pedroches batholit, the Alcudia anticline - Domo Extremeño, the Almadén syncline, the fold structures located to the north and the Toledo fault. We present the results of this profile, which consists of 33 MT sites, with the five components of the electromagnetic field and period ranging from 1000 Hz to 1000 s. In each MT site a TEM sounding was carried out in order to characterize the shallow electrical resistivity and to control the galvanic distortion (static shift). The results of two-dimensional inversion reveal a high conductivity zone with the transition OMZ/CIZ. Apart from the sallow structure, the most striking feature is a high conductive layer at middle to lower crust in the whole CIZ, confirming the prolongation of the same layer detected in the OMZ in previous studies.

    The Baltic Sea (Central Europe) is surrounded by coastal regions with long histories of industrialization. The heavy metal profiles in the sediments in the center of the Arkona Basin, one of the depressions of the southern Baltic Sea area, clearly reflect the historical anthropogenic influence. The Arkona Basin-is the final sink for materials derived from the Oder river which drains a highly polluted industrial area of Eastern Europe. Surficial muddy sediments from a close-meshed field of sampling-points were analyzed for distribution patterns of aliphatics and quantities and ratios of selected polycyclic aromatic hydrocarbons (PAH). These compounds are thought to reflect anthropogenic pollution related to emissions from traffic, heating, etc. We use these marker substances to test if the basin sediments reflect riverine input, and if additional sources can be identified.

  11. Family medicine in post-communist Europe needs a boost. Exploring the position of family medicine in healthcare systems of Central and Eastern Europe and Russia

    2012-01-01

    Background The countries of Central and Eastern Europe have experienced a lot of changes at the end of the 20th century, including changes in the health care systems and especially in primary care. The aim of this paper is to systematically assess the position of family medicine in these countries, using the same methodology within all the countries. Methods A key informants survey in 11 Central and Eastern European countries and Russia using a questionnaire developed on the basis of systematic literature review. Results Formally, family medicine is accepted as a specialty in all the countries, although the levels of its implementation vary across the countries and the differences are important. In most countries, solo practice is the most predominant organisational form of family medicine. Family medicine is just one of many medical specialties (e.g. paediatrics and gynaecology) in primary health care. Full introduction of family medicine was successful only in Estonia. Conclusions Some of the unification of the systems may have been the result of the EU request for adequate training that has pushed the policies towards higher standards of training for family medicine. The initial enthusiasm of implementing family medicine has decreased because there was no initiative that would support this movement. Internal and external stimuli might be needed to continue transition process. PMID:22409775

    Context. We present the largest catalog of detailed stellar kinematics of the central parts of nearby galaxies, which includes higher moments of the line-of-sight velocity distribution (LOSVD) function represented by the Gauss-Hermite series. The kinematics is measured on a sample of galaxies selected from the Arecibo Legacy Fast ALFA (Alfalfa) survey using spectroscopy from the Sloan Digital Sky Survey (SDSS DR7). Aims: The SDSS DR7 offers measurements of the LOSVD based on the assumption of a pure Gaussian shape of the broadening function caused by the combination of rotational and random motion of the stars in galaxies. We discuss the consequences of this oversimplification since the velocity dispersion, one of the measured quantities, often serves as the proxy to important modeling parameters such as the black-hole mass and the virial mass of galaxies. Methods: The publicly available pPXF code is used to calculate the full kinematical profile for the sample galaxies including higher moments of their LOSVD. Both observed and synthetic stellar libraries were used and the related template mismatch problem is discussed. Results: For the whole sample of 2180 nearby galaxies reflecting morphological distribution characteristic for the local Universe, we successfully recovered stellar kinematics of their central parts, including higher order moments of the LOSVD function, for signal-to-noise above 50. Conclusions: We show the consequences of the oversimplification of the LOSVD function with Gaussian function on the velocity dispersion for the empirical and the synthetic stellar library. For the empirical stellar library, this approximation leads to an increase in the virial mass of 13% on average, while for the synthetic library the effect is weaker, with an increase of 9% on average. Systematic erroneous estimates of the velocity dispersion comes from the use of the synthetic stellar library instead of the empirical one and is much larger than the value imposed by

    This paper reports the first find of pika remains in the Iberian Peninsula, at a site in central Spain. A fragmented mandible of Ochotona cf. pusilla was unearthed from Layer 3 (deposited some 63.4±5.5 ka ago as determined by thermoluminescence) of the Buena Pinta Cave. This record establishes new limits for the genus geographic distribution during the Pleistocene, shifting the previous edge of its known range southwest by some 500 km. It also supports the idea that, even though Europe's alpine mountain ranges represented a barrier that prevented the dispersal into the south to this and other taxa of small mammals from central and eastern Europe, they were crossed or circumvented at the coldest time intervals of the end of the Middle Pleistocene and of the Late Pleistocene. During those periods both the reduction of the forest cover and the emersion of large areas of the continental shelf due to the drop of the sea level probably provided these species a way to surpass this barrier. The pika mandible was found accompanying the remains of other small mammals adapted to cold climates, indicating the presence of steppe environments in central Iberia during the Late Pleistocene.

    formula for each country. In order to get the completeness periods for various magnitude ranges, the combined catalogue as well as each subcatalogue have been analyzed following the method of Stepp (1972). We can show that the new composite catalogue fulfills the critical minimum observation period for all intensity classes except IX and higher. A stable estimate of mean recurrence period of intensity IV is 80 years of homogeneous observations from 1900 to 1980 and for intensity V, the observation period is 120 years. A stable estimate of mean recurrence period for intensity VI is about 115 years and for intensity vii is 30 years. The homogeneous interval for maximum intensity VIII is 200 years. Maximum intensity IX earthquakes are not completely definitive for whole 962 years period. In addition, the analysis of each subcatalogue leads to similar results, except the ACORN catalogue. Therefore, the newly complied catalogue for Austria and surrounding areas is a suitable data base for seismic hazard assessment in Austria.

    Chromium is one of the most toxic elements, especially in its dissolved Cr(VI) form. In the Czech Republic (Central Europe), massive contamination of groundwater has been reported at more than 200 industrial operations. Under suitable conditions, i.e., low Eh, and high availability of reductive agents, Cr(VI) in groundwater may be spontaneously reduced to solid, largely non-toxic Cr(III). This process is associated with a Cr isotope fractionation, with the residual liquid Cr(VI) becoming enriched in the heavier isotope 53Cr. At industrial operations that have been closed and/or where no further leakage of Cr(VI) occurs, the contaminated groundwater plume may be viewed as a closed system. At such sites, an increasing degree of Cr(VI) reduction should result in an increasing del53/52Cr value of the residual liquid. Here we present del53/52Cr systematics at four contaminated Czech sites, focusing on groundwaters. At two of the four sites (Zlate Hory, Loucna) we were also able to analyze the source of contamination. Chromium in the electroplating solutes was isotopically relatively light, with del53/52Cr values <1 per mil. At the remaining two sites (Letnany and Velesin), the Cr isotope signature of the source of contamination was not known. At all four sites, most del53/52Cr values were positive, with means higer than 1 per mil: At Zlate Hory, del53/52Cr ranged between -2.2 and +3.0 per mil (mean of +1.5 per mil); at Loucna, del53/52Cr ranged between 0 and +4.0 per mil (mean of +1.7 per mil); at Letnany, del53/52Cr ranged between +2.0 and +4.5 per mil (mean of +3.2 per mil); and at Velesin, del53/52Cr ranged between +0.5 and +4.5 per mil (mean of +2.7 per mil). Cr(VI) reduction may proceed at Zlate Hory and Loucna, where del53/52Cr(VI) values in groundwater were on average higher than those of the contamination source. At these two sites, our Cr isotope data are not consistent with the existing estimates of the amount of dissolved and precipitated Cr: The pool size of

    The authors describe the situation of foot and mouth disease (FMD) in Europe over the past 70 years and analyse the origin of the disease and methods of control, particularly since preventive vaccination was banned in Europe in the early 1990s. Since then, and until 2001, despite several incursions of the virus, the disease has always been contained and eradicated rapidly. Therefore, the ban on vaccination did not result in an increase of FMD outbreaks. However, the massive outbreak which took place in 2001 in the United Kingdom (UK) with 2,030 outbreaks, raised questions on the policy utilised to date to control the disease in Europe. In future, the utilisation of ring vaccination should be considered as an alternative to mass culling of large numbers of animals. Based on the recent source of introduction of the virus, the authors review the lines of defence which should be reinforced to reduce the risk of further introduction of the disease. The FMD situation in the Commonwealth of Independent States (CIS) is also examined. The situation in the Central Asian Republics and the Caucasian region deteriorated after the collapse of the Soviet Union, despite the continuous effort of Russia to support these countries. International support is needed to prevent FMD from becoming endemic in the region.

    Computation of probabilistic earthquake hazard requires an estimate of Mmax, the maximum earthquake magnitude thought to be possible within a specified geographic region. This report is Part A of an Open-File Report that describes the construction of a global catalog of moderate to large earthquakes, from which one can estimate Mmax for most of the Central and Eastern United States and adjacent Canada. The catalog and Mmax estimates derived from it were used in the 2014 edition of the U.S. Geological Survey national seismic-hazard maps. This Part A discusses prehistoric earthquakes that occurred in eastern North America, northwestern Europe, and Australia, whereas a separate Part B deals with historical events.

    Several traces may reveal the post-mortem relocation of a corpse. Insects are particularly useful for that purpose. The use of insects for inferring the transfer of a corpse rests on a premise that particular species colonise corpses in different habitats. However, only some insects reveal a strong preference for a given type of habitat. In order to find those insects which colonise corpses exclusively in open habitats, as opposed to forest habitats, a pig carrion study was made in rural open and rural forest habitats of Central Europe. Lucilia sericata (Diptera: Calliphoridae), Dermestes frischi, Dermestes laniarius (Coleoptera: Dermestidae), Omosita colon, some species of Nitidula (Coleoptera: Nitidulidae) and Necrobia rufipes (Coleoptera: Cleridae) were found to breed exclusively in open habitats. Only Oiceoptoma thoracicum (Coleoptera: Silphidae) avoided definitely breeding in open habitats.

Only O. thoracicum may be classified as an indicator of the relocation in an opposite direction. PMID:23890643

    This study examines the hypothesis that Danish agricultural areas are the main source of airborne Alternaria spores in Copenhagen, Denmark. We suggest that the contribution to the overall load is mainly local or regional, but with intermittent long distance transport (LDT) from more remote agricultural areas. This hypothesis is supported by investigating a 10 yr bi-hourly record of Alternaria spores in the air from Copenhagen. This record shows 232 clinically relevant episodes (daily average spore concentration above 100 m-3) with a distinct daily profile. The data analysis also revealed potential LDT episodes almost every year. A source map and analysis of atmospheric transport suggest that LDT always originates from the main agricultural areas in Central Europe. A dedicated emission study in cereal crops under harvest during 2010 also supports our hypothesis. The emission study showed that although the fields had been treated against fungal infections, harvesting still produced large amounts of airborne fungal spores. It is likely that such harvesting periods can cause clinically relevant levels of fungal spores in the atmosphere. Our findings suggest that crop harvest in Central Europe causes episodes of high airborne Alternaria spore concentrations in Copenhagen as well as other urban areas in this region. It is likely that such episodes could be simulated using atmospheric transport models.

    Several traces may reveal the post-mortem relocation of a corpse. Insects are particularly useful for that purpose. The use of insects for inferring the transfer of a corpse rests on a premise that particular species colonise corpses in different habitats. However, only some insects reveal a strong preference for a given type of habitat. In order to find those insects which colonise corpses exclusively in open habitats, as opposed to forest habitats, a pig carrion study was made in rural open and rural forest habitats of Central Europe. Lucilia sericata (Diptera: Calliphoridae), Dermestes frischi, Dermestes laniarius (Coleoptera: Dermestidae), Omosita colon, some species of Nitidula (Coleoptera: Nitidulidae) and Necrobia rufipes (Coleoptera: Cleridae) were found to breed exclusively in open habitats. Only Oiceoptoma thoracicum (Coleoptera: Silphidae) avoided definitely breeding in open habitats. Sarcophaga caerulescens (Diptera: Sarcophagidae) regularly bred in open habitats but rarely bred in forests. Accordingly, L. sericata, D. frischi, O. colon, species of Nitidula and supposedly N. rufipes may be classified as indicators of corpse relocation from rural open to rural forest habitats of Central Europe. Only O. thoracicum may be classified as an indicator of the relocation in an opposite direction.

    The ImplementatioN of perSonalized medicine In NSCLC in Central Europe: EGFR testing, Histopathology, and clinical feaTures (INSIGHT) observational study assessed both implementation of epidermal growth factor receptor (EGFR) mutation testing and treatment of patients with advanced EGFR mutation-positive non-small-cell lung cancer (NSCLC) in a real-world setting in Central Europe. A total of 1785 patients from 14 cancer centers of six Central European countries were enrolled. EGFR mutations were detected in tumors of 13.8% of the patients. More than 70% of patients with advanced EGFR mutation-positive NSCLC received EGFR tyrosine kinase inhibitors as first-line therapy. The INSIGHT study demonstrated the establishment of EGFR mutation testing, a mutation rate consistent with other Caucasian patients populations, and adherence to current guidelines regarding treatment of patients with EGFR mutation-positive tumors in Central Europe.

    An international cooperative project on distribution of ozone in the Carpathian Mountains, Central Europe was conducted from 1997 to 1999. Results of that project indicated that in large parts of the Carpathian Mountains, concentrations of ozone were elevated and potentially phytotoxic to forest vegetation. That study led to the establishment of new long-term studies on ecological changes in forests and other ecosystems caused by air pollution in the Retezat Mountains, Southern Carpathians, Romania and in the Tatra Mountains, Western Carpathians on the Polish-Slovak border. Both of these important mountain ranges have the status of national parks and are Man & the Biosphere Reserves. In the Retezat Mountains, the primary research objective was to evaluate how air pollution may affect forest health and biodiversity. The main research objective in the Tatra Mountains was to evaluate responses of natural and managed Norway spruce forests to air pollution and other stresses. Ambient concentrations of ozone (O(3)), sulfur dioxide (SO(2)), nitrogen oxides (NO(x)) as well as forest health and biodiversity changes were monitored on densely distributed research sites. Initial monitoring of pollutants indicated low levels of O(3), SO(2), and NO(x) in the Retezat Mountains, while elevated levels of O(3) and high deposition of atmospheric sulfur (S) and nitrogen (N) have characterized the Tatra Mountains. In the Retezat Mountains, air pollution seems to have little effect on forest health; however, there was concern that over a long time, even low levels of pollution may affect biodiversity of this important ecosystem. In contrast, severe decline of Norway spruce has been observed in the Tatra Mountains. Although bark beetle seems to be the immediate cause of that decline, long-term elevated levels of atmospheric N and S depositions and elevated O(3) could predispose trees to insect attacks and other stresses.

    The paper presents lead isotope data from 211 samples from Phanerozoic lead-bearing ore occurrences in Central Europe, particularly from the Southern part of the former German Democratic Republic. The data are interpreted in terms of Amov's dynamic model of continuous lead isotope evolution. The relationships between thoro-genic and urano-genic model ages and the source of lead in different regional units are discussed. We observed differences in lead isotope evolution in the Hercynian internides and externides. Within the Moldanubian and Saxothuringian zones we distinguish five main lead-bearing ore associations: (1) Cambrian, stratiform base metal (Hermsdorf-Waldsassen; 206Pb/ 204Pb=17.50 17.70), (2) Devonian, vein type Sb-bearing, metamorphogene (neumühle-Hartmannsdorf; 17.80 18.00), (3) Upper Carboniferous-Permian, polymetallic, including tin, vein type (Kutna hora-Freiberg-Altenberg; 18.00 18.20), (4) Triassic (-Jurassic), Pb-Ba, vein type (Střibro-Halsbrücke; 18.20 18.60), (5) Cenozoic, polymetallic, vein type, riftogene (Roztoky-Banska Štiavnica; 18.80 19.10). Pb isotope characteristics from ores of the Montagne Noire and the Brioude-Massiac district correspond to this subdivision. Ore associations from the Rheno-Hercynian zone display higher 207Pb/204Pb ratios which can be explained by more evolved and less metamorphosed source rocks. Mineralizations of the eastern Harz (Straßberg-Neudorf) belong to the Permian association, those from the western Harz (Clausthal-Bad Grund) to the Triassic-Jurassic. Because of Pb isotope agreement the stratabound Rammelsberg and the vein bound Ramsbeck-I mineralization are presumed to be isogenetic. Pb isotope identity of distinct mineralizations in the basement zone (Halsbrücke-Bad Grund) and in the Triassic sediments (Gorny Slask-Mechernich-Bleiglanzbänke) suggests a strong genetic coherence.

    characterized the climate variability of MIS 3. Mild climate conditions in early MIS 3 caused large-scale deglaciation of the Fennoscandian Ice Sheet, and ice-free conditions with Betula-dominated vegetation (including tree birch) persisted over large parts of Fennoscandia, possibly interrupted by glaciation, during major part of MIS 3 till ca 35 ka BP. Overall, MIS 5 was mostly mild with warmest or peak interglacial conditions at the very start during MIS 5e. MIS 4-2 was mostly cold with most extreme or peak glacial conditions in the closing phase during MIS 2. This points to a subdivision of the last climate cycle into an early, overall mild interglacial half and a late, overall cold glacial half, each with duration of ca 50 ka. This review also shows that the climate variability in central and northern Europe during the LI-G cycle was mostly in degrees of continentality with major shifts in winter temperature and precipitation values; summer temperatures, on the other hand, remained largely unchanged. It points to the waxing and waning of sea-ice over the North Atlantic Ocean as a possible characteristic feature of the Late Pleistocene. The present compilation, based on long terrestrial sequences, high-resolution multi-proxy data from the oceans, and quantified paleo-climate data, strongly favors a definition of entire Marine Oxygen Isotope Stage 5 as the Last Interglacial similar as in the original marine stratigraphy and the stratigraphy at La Grande Pile in France. The proxy-based climate data places the start of the Last Glacial at the base of MIS 4 and the northwest European Pleniglacial. It shows that the division between the Eemian (MIS 5e) and the Early Weichselian (MIS 5d-a) is not useful, as not relevant from a climate point of view.

    Canine babesiosis is a severe and potentially life threatening infection. In Europe, Babesia canis is considered to be the most common species responsible for the disease. We report two cases of babesiosis caused by Babesia gibsoni. The polymerase chain reaction, restriction fragment length polymorphism analysis and further sequencing of 18S rRNA gene fragments from blood samples of both dogs revealed the identity of isolates with B. gibsoni genotypes from other dogs worldwide. This species was previously not known to infect dogs in Slovakia. It is resistant to traditional anti-babesial therapy. Therefore, correct diagnosis is crucial for the successful treatment, especially in dogs with hemolytic anemia and febrile conditions.

    Background: Major differences exist in residency training, and the structure and quality of residency programs differ between different countries and teaching centers. It is of vital importance that a better understanding of the similarities and differences in plastic surgery training be ascertained as a means of initiating constructive discussion and commentary among training programs worldwide. In this study, the authors provide an overview of plastic surgery training in the United States and Europe. Methods: A survey was sent to select surgeons in 10 European countries that were deemed to be regular contributors to the plastic surgery literature. The questions focused on pathway to plastic surgery residency, length of training, required pretraining experience, training scheme, research opportunities, and examinations during and after plastic surgery residency. Results: Plastic surgery residency training programs in the United States differ from the various (selected) countries in Europe and are described in detail. Conclusions: Plastic surgery education is vastly different between the United States and Europe, and even within Europe, training programs remain heterogeneous. Standardization of curricula across the different countries would improve the interaction of different centers and facilitate the exchange of vital information for quality control and future improvements. The unique characteristics of the various training programs potentially provide a basis from which to learn and to gain from one another. PMID:27257571

    Evidence of long central nerve fibre degeneration (axonal spheroids) in the lateral cuneate nuclei was found in all eight Thoroughbreds affected clinically and subclinically with equine laryngeal hemiplegia, but in only one of six control animals. It was considered that these spheroids may signify a central nervous component of the disease process of laryngeal hemiplegia although until further investigations are performed no firm conclusions regarding the relationship of these findings with laryngeal hemiplegia could be made. Examination of the left and right nucleus ambiguus of clinical and subclinical laryngeal hemiplegic horses revealed no pathological alterations.

    Ruminant milk and dairy products are important food resources in many European, African, and Middle Eastern societies. These regions are also associated with derived genetic variants for lactase persistence. In mammals, lactase, the enzyme that hydrolyzes the milk sugar lactose, is normally down-regulated after weaning, but at least five human populations around the world have independently evolved mutations regulating the expression of the lactase-phlorizin-hydrolase gene. These mutations result in a dominant lactase persistence phenotype and continued lactase tolerance in adulthood. A single nucleotide polymorphism (SNP) at C/T-13910 is responsible for most lactase persistence in European populations, but when and where the T-13910 polymorphism originated and the evolutionary processes by which it rose to high frequency in Europe have been the subject of strong debate. A history of dairying is presumed to be a prerequisite, but archaeological evidence is lacking. In this study, DNA was extracted from the dentine of 36 individuals excavated at a medieval cemetery in Dalheim, Germany. Eighteen individuals were successfully genotyped for the C/T-13910 SNP by molecular cloning and sequencing, of which 13 (72%) exhibited a European lactase persistence genotype: 44% CT, 28% TT. Previous ancient DNA-based studies found that lactase persistence genotypes fall below detection levels in most regions of Neolithic Europe. Our research shows that by AD 1200, lactase persistence frequency had risen to over 70% in this community in western Central Europe. Given that lactase persistence genotype frequency in present-day Germany and Austria is estimated at 71-80%, our results suggest that genetic lactase persistence likely reached modern levels before the historic population declines associated with the Black Death, thus excluding plague-associated evolutionary forces in the rise of lactase persistence in this region. This new evidence sheds light on the dynamic evolutionary

    We investigated the diversity of Bartonella in Apodemus agrarius, an important rodent of peri-domestic habitats, which has spread into Europe in the past 1000 years. Spleen samples of 344 A. agrarius from Eastern Slovakia were screened for the presence of Bartonella spp. using 16S-23S rRNA internal transcribed spacer region and bacteria were detected in 9% of rodents. Based on sequencing of three housekeeping genes (gltA, rpoB and groEL) Bartonella genotypes were ascribed to the species typical for mice and voles: B. grahamii, B. taylorii and B. birtlesii. However, the study also confirmed presence of genotypes belonging to the B. clarridgeiae/B. rochalimae clade, and the B. elizabethae/B. tribocorum clade, which are not commonly found in woodland rodents. In addition, a potential recombination event between these two genotypes was noted, which highlights an important role of A. agrarius in shaping Bartonella diversity and evolution. PMID:27279125

    During the summer months of the year 2001, six forensic cases (one is reported in the present paper), a pig carrion study in the city of Vienna (latitude 48 degrees 12'N, longitude 16 degrees 22'E) and several liver-baited traps north of Vienna, yielded large numbers of maggots of the blowfly Chrysomya albiceps (Wiedemann) (Diptera: Calliphoridae). Apart from some records from France, reports of C. albiceps from the palearctic region north of the Alps (i.e. north of a latitude of 48 degrees N) have been scarce. Our findings provided an opportunity to derive developmental schedules for C. albiceps at five different constant temperatures (15, 20, 25, 30, 35 degrees C). The minimal duration of development from oviposition to adult was inversely related to temperature, ranging from 8.3 +/- 0.5 days at 35 degrees C to 19.2 +/- 0.92 days at 20 degrees C. Although eggs hatched after 1.9 +/- 0.16 days at 15 degrees C, larvae did not complete development and frequently died during the first instar stage. We also found a high mortality rate (up to 99%) of native L. sericata larvae caused by predation of C. albiceps larvae under laboratory conditions, indicating a high susceptibility of L. sericata to attack by C. albiceps. Apart from this, the current and possible future distribution of C. albicepsin Europe is discussed. The northward expansion of its range beyond southern Europe obviously decreases the value of C. albiceps in estimating the site of death, in that it is no longer exclusive to southern European regions. Moreover, the aggressive feeding behaviour of second and third instar larve of C. albiceps could reset the post-mortem insect clock by clearing a corpse of all earlier arrivers.

    This paper reports the first find of pika remains in the Iberian Peninsula, at a site in central Spain. A fragmented mandible of Ochotona cf. pusilla was unearthed from Layer 3 (deposited some 63.4±5.5 ka ago as determined by thermoluminescence) of the Buena Pinta Cave. This record establishes new limits for the genus geographic distribution during the Pleistocene, shifting the previous edge of its known range southwest by some 500 km. It also supports the idea that, even though Europe’s alpine mountain ranges represented a barrier that prevented the dispersal into the south to this and other taxa of small mammals from central and eastern Europe, they were crossed or circumvented at the coldest time intervals of the end of the Middle Pleistocene and of the Late Pleistocene. During those periods both the reduction of the forest cover and the emersion of large areas of the continental shelf due to the drop of the sea level probably provided these species a way to surpass this barrier. The pika mandible was found accompanying the remains of other small mammals adapted to cold climates, indicating the presence of steppe environments in central Iberia during the Late Pleistocene.

    Pulsatilla patens s.s. is a one of the most endangered plant species in Europe. The present range of this species in Europe is highly fragmented and the size of the populations has been dramatically reduced in the past 50 years. The rapid disappearance of P. patens localities in Europe has prompted the European Commission to initiate active protection of this critically endangered species. The aim of this study was to estimate the degree and distribution of genetic diversity within European populations of this endangered species. We screened 29 populations of P. patens using a set of six microsatellite primers. The results of our study indicate that the analyzed populations are characterized by low levels of genetic diversity (Ho = 0.005) and very high levels of inbreeding (FIS = 0.90). These results suggest that genetic erosion could be partially responsible for the lower fitness in smaller populations of this species. Private allelic richness was very low, being as low as 0.00 for most populations. Average genetic diversity over loci and mean number of alleles in P. patens populations were significantly correlated with population size, suggesting severe genetic drift. The results of AMOVA point to higher levels of variation within populations than between populations.The results of Structure and PCoA analyses suggest that the genetic structure of the studied P. patens populations fall into three clusters corresponding to geographical regions. The most isolated populations (mostly from Romania) formed a separate group with a homogeneous gene pool located at the southern, steppic part of the distribution range. Baltic, mostly Polish, populations fall into two genetic groups which were not fully compatible with their geographic distribution.Our results indicate the serious genetic depauperation of P. patens in the western part of its range, even hinting at an ongoing extinction vortex. Therefore, special conservation attention is required to maintain the populations

    Pulsatilla patens s.s. is a one of the most endangered plant species in Europe. The present range of this species in Europe is highly fragmented and the size of the populations has been dramatically reduced in the past 50 years. The rapid disappearance of P. patens localities in Europe has prompted the European Commission to initiate active protection of this critically endangered species. The aim of this study was to estimate the degree and distribution of genetic diversity within European populations of this endangered species. We screened 29 populations of P. patens using a set of six microsatellite primers. The results of our study indicate that the analyzed populations are characterized by low levels of genetic diversity (Ho = 0.005) and very high levels of inbreeding (FIS = 0.90). These results suggest that genetic erosion could be partially responsible for the lower fitness in smaller populations of this species. Private allelic richness was very low, being as low as 0.00 for most populations. Average genetic diversity over loci and mean number of alleles in P. patens populations were significantly correlated with population size, suggesting severe genetic drift.

  19. Extreme floods in central Europe over the past 500 years: Role of cyclone pathway ``Zugstrasse Vb''

    Anthropogenically induced climate change has been hypothesized to add to the risk of extreme river floods because a warmer atmosphere can carry more water. In the case of the central European rivers Elbe and Oder, another possibility that has been considered is a more frequent occurrence of a weather situation of the type "Zugstrasse Vb," where a low-pressure system travels from the Adriatic region northeastward, carrying moist air and bringing orographic rainfall in the mountainous catchment areas (Erzgebirge, Sudeten, and Beskids). Analysis of long, homogeneous records of past floods allows us to test such ideas. M. Mudelsee and co-workers recently presented flood records for the middle parts of the Elbe and Oder, which go continuously back to A.D. 1021 and A.D. 1269, respectively. Here we review the reconstruction and assess the data quality of the records, which are based on combining documentary data from the interval up to 1850 and measurements thereafter, finding both the Elbe and Oder records to provide reliable information on heavy floods at least since A.D. 1500. We explain that the statistical method of kernel occurrence rate estimation can overcome deficiencies of techniques previously used to investigate trends in the occurrence of climatic extremes, because it (1) allows nonmonotonic trends, (2) imposes no parametric restrictions, and (3) provides confidence bands, which are essential for evaluating whether observed trends are real or came by chance into the data. We further give a hypothesis test that can be used to evaluate monotonic trends. On the basis of these data and methods, we find for both the Elbe and Oder rivers (1) significant downward trends in winter flood risk during the twentieth century, (2) no significant trends in summer flood risk in the twentieth century, and (3) significant variations in flood risk during past centuries, with notable differences between the Elbe and Oder. The observed trends are shown to be both robust against

    A checklist of ciliates from the family Euplotidae recorded in the territory of Slovakia, Central Europe was assembled. Altogether, 11 species belonging to three genera of the family Euplotidae have been reported there: Euplotes alatus, Euplotes charon, Euplotes moebiusi, Euplotoides aediculatus, Euplotoides eurystomus, Euplotoides patella, Euplotoides woodruffi, Euplotopsis affinis, Euplotopsis finki, Euplotopsis muscicola, and Euplotopsis novemcarinata. However, records of the marine species E. alatus and E. charon are doubtful and very likely represent misidentifications of E. moebiusi. Since the euryhaline species E. woodruffi was found for the first time in Slovakia, its morphology is described. Based on the literature data and our own observations, the present checklist is also accompanied with distribution data on the 11 aforementioned species. As concerns ecology, Slovak euplotids typically occurred in freshwater bodies having higher trophic levels. Only two species, E. finki and E. muscicola, were isolated from terrestrial habitats, especially, from mosses, leaf-litter, and decaying wood mass. PMID:25781253

    The widespread paradigm in ecology that community structure determines function has recently been challenged by the high complexity of microbial communities. Here, we investigate the patterns of and connections between microbial community structure and microbially-mediated ecological function across different forest management practices and temporal changes in leaf litter across beech forest ecosystems in Central Europe. Our results clearly indicate distinct pattern of microbial community structure in response to forest management and time. However, those patterns were not reflected when potential enzymatic activities of microbes were measured. We postulate that in our forest ecosystems, a disconnect between microbial community structure and function may be present due to differences between the drivers of microbial growth and those of microbial function.

    While there is broad agreement that the way that health care providers are paid affects their performance, the empirical literature on the impacts of provider payment reforms is surprisingly thin. During the 1990s and early 2000s, many European and Central Asian (ECA) countries shifted from paying hospitals through historical budgets to fee-for-service (FFS) or patient-based payment (PBP) methods (mostly variants of diagnosis-related groups, or DRGs). Using panel data on 28 countries over the period 1990-2004, we exploit the phased shift from historical budgets to explore aggregate impacts on hospital throughput, national health spending, and mortality from causes amenable to medical care. We use a regression version of difference-in-differences (DID) and two variants that relax the DID parallel trends assumption. We find that FFS and PBP both increased national health spending, including private (i.e. out-of-pocket) spending. However, they had different effects on inpatient admissions (FFS increased them; PBP had no effect), and average length of stay (FFS had no effect; PBP reduced it). Of the two methods, only PBP appears to have had any beneficial effect on "amenable mortality", but we found significant impacts for only a couple of causes of death, and not in all model specifications.

    Spores of the genus Alternaria belong to one of the most prevailing constituents of the air in all regions of the world. They form infectious inoculum of numerous plant species as well as severe inhaled allergies. The aim of this study was to compare the biological pollution with Alternaria spores of the air of 12 cities located in central and eastern Europe. The experiment was done in 2010 and it covered the territory of Latvia (LV), Lithuania (LT), Poland (PL) and Ukraine (UA). The spores were counted using an identical method and standard equipment (7-day Lanzoni volumetric sampler) followed by extensive statistical calculations. The timing of the day of maximum concentration changed mainly along the N-S direction and had a positive correlation with latitude. The most important factor determining the increase in Alternaria spore concentration was the temperature, whereas other weather parameters were not related or of low significance. Regardless of geographical location, the first phase of the season (0-0.9 % of Alternaria spores in the air) was the longest (up to 60 days) and the last (97.5 to 99 %) was the shortest (22 days or less). The means of daily concentrations of Alternaria spores ranged from 11 spores m(-3) in Klaipeda (LT, Baltic Sea coast) to 187 in Poznan (west PL, agricultural plain). The threshold value of 80 spores m(-3) that triggers the first allergy symptoms was exceeded in 8 to 86 days (Vinnitsa, UA, temperate continental, forest-steppes region). There were considerable differences between the highest number of spores per cubic metre of air, varying from 139 in the north (Klaipeda, LT) to 2,295 in central west (Poznan, PL). The biological pollution by Alternaria spores in several places of central and eastern Europe was high; the number of days exceeding the threshold value of 300 spores m(-3) connected with serious health problems of atopic people ranged from 0 to 1 on the north (LV, LT) to 29 in central west (Poznan, PL).

    The main goal of presented work is to evaluate the accuracy of modelling the atmospheric transport and transformation on regional scale, performed with 25 km grid spacing. The coupled Mesoscale Weather Model - Chemical Transport Model (CTM) has been applied for Europe under European-American AQMEII project (Air Quality Modelling Evaluation International Initiative - http://aqmeii.jrc.ec.europa.eu/). The modelling domain was centered over Denmark (57.00°N, 10.00°E) with 172 x 172 grid points in x and y direction. The map projection choice was Lambert conformal. In the applied modelling system the Comprehensive Air Quality Model with extensions (CAMx) from ENVIRON International Corporation (Novato, California) was coupled off-line to the Weather Research and Forecasting (WRF), developed by National Center for Atmospheric Research (NCAR). WRF-CAMx simulations have been carried out for 2006. The anthropogenic emisions database has been provided by TNO (Netherlands Organisation for Applied Scientific Research) under AQMEII initiative. Area and line emissions were proceeded by emission model EMIL (Juda-Rezler et al., 2012) [1], while for the point sources the EPS3 model (Emission Processor v.3 from ENVIRON) was implemented in order to obtain vertical distribution of emission. Boundary conditions were acquired from coupling the GEMS (Global and regional Earth-system Monitoring using Satellite and in-situ data) modelling system results with satellite observations. The modelling system has been evaluated for the area of Central-Eastern Europe, regarding ozone and particulate matter (PM) concentrations. For each pollutant measured data from rural background AirBase and EMEP stations, with more than 75% of daily data, has been used. Original 'operational' evaluation methodology, proposed by Juda-Rezler et al. (2012) was applied. Selected set of metrics consists of 5 groups: bias measures, error measures, correlation measures, measures of model variance and spread, which

    This study assessed the programmes, resources, and needs of HIV-prevention nongovernmental organizations (NGOs) in 75 countries in Africa, Central/Eastern Europe and Central Asia, Latin America and the Caribbean. Multiple databases and expert recommendations were used to identify one major HIV-prevention NGO in the capital or a large city in each country, and in-depth interviews were conducted with each NGO Director. Most NGOs are carrying out their programmes with minimal funding and few regularly employed personnel. Most are highly dependent on international donors, but reliance on small grants with short funding periods limits programme development capacity. HIV-prevention activities varied by region, with African NGOs most likely to use peer education and community awareness events; Eastern European NGOs most likely to offer needle exchange; Latin American NGOs to have resource centres and offer risk reduction programmes; and Caribbean organizations to use mass education approaches. Across regions, NGOs most often targeted the general public and youth, although specialized at-risk groups were the additional focus of attention in some regions. Limited funding, governmental indifference or opposition, AIDS stigma, and social discomfort discussing sex were often cited as barriers to new HIV-prevention programmes. NGOs are critical service providers. However, their funding, programmes, and resource capacities must be strengthened if NGOs are to realize their full potential in HIV prevention. PMID:16282071

  14. Centralized Authorization Using a Direct Service, Part II

    SciTech Connect

    Wachsmann, A

    2004-06-09

    Authorization is the process of deciding if entity X is allowed to have access to resource Y. Determining the identity of X is the job of the authentication process. One task of authorization in computer networks is to define and determine which user has access to which computers in the network. On Linux, the tendency exists to create a local account for each single user who should be allowed to logon to a computer. This is typically the case because a user not only needs login privileges to a computer but also additional resources like a home directory to actually do some work. Creating a local account on every computer takes care of all this. The problem with this approach is that these local accounts can be inconsistent with each other. The same user name could have a different user ID and/or group ID on different computers. Even more problematic is when two different accounts share the same user ID and group ID on different computers: User joe on computer1 could have user ID 1234 and group ID 56 and user jane on computer2 could have the same user ID 1234 and group ID 56. This is a big security risk in case shared resources like NFS are used. These two different accounts are the same for an NFS server so that these users can wipe out each other's files. The solution to this inconsistency problem is to have only one central, authoritative data source for this kind of information and a means of providing all your computers with access to this central source. This is what a ''Directory Service'' is. The two directory services most widely used for centralizing authorization data are the Network Information Service (NIS, formerly known as Yellow Pages or YP) and Lightweight Directory Access Protocol (LDAP).

    • Background and aims: Rainfed sectors of agriculture such as nature-close forestry, non-irrigated agriculture and animal husbandry on nature-close pastures are threatened by projected climate change especially in low-elevation regions in Southeast Europe, where precipitation is the limiting factor of production and ecosystem stability. Therefore the importance of complex, long term management planning and of land use optimization is increasing. The aim of the Decision Support System under development is to raise awareness and initiate preparation for frequency increase of extreme events, disasters and economic losses in the mentioned sectors. • Services provided: The Decision Support System provides GIS-supported information about the most important regional and local risks and mitigation options regarding climate change impacts, projected for reference periods until 2100 (e.g. land cover/use and expectable changes, potential production, water and carbon cycle, biodiversity and other ecosystem services, potential pests and diseases, tolerance limits etc.). The projections are referring first of all on biological production (natural produce), but the System includes also social and economic consequences. • Methods: In the raster based system, the latest image processing technology is used. We apply fuzzy membership functions, Support Vector Machine and Maximum Likelihood classifier. The System is developed in the first step for a reference area in SW Hungary (Zala county). • Novelty: The coherent, fine-scale regional system integrates the basic information about present and projected climates, extremes, hydrology and soil conditions and expected production potential for three sectors of agriculture as options for land use and conservation. • Funding: The development of the Decision Support System "Agrárklíma" is supported by TÁMOP-4.2.2.A-11/1/KONV and 4.2.2.B-10/1-2010-0018 "Talentum" joint EU-national research projects.

    Ten years ago, on 26 April 1986, as a consequence of an accident in Unit 4 of the Chernobyl-NPP, a large quantity of radioactive material was released into the atmosphere for some days. This material was spread over wide areas of Europe. Due to variable weather conditions the activity concentrations in air varied considerably in different regions. Also as a consequence of large variations in precipitation intensity-particularly in the regions of Southeastern Germany, Austria and Southern Switzerland-up to 100 kBq m{sup -2} {sup 137}Cs were deposited on the soil. Due to fallout, washout, and/or rainout, a range of foodstuffs were contaminated, and foodstuffs directly exposed to the fallout [vegetables and green fodder (grass)] showed the highest contamination levels. Consequently, milk also showed a significantly increased activity concentration, in particular of {sup 131}I. In the following years contamination in all kinds of foodstuffs decreased, but elevated contamination levels in special pathways like venison and mushrooms are still observed to date. This contamination resulted in additional exposure, mainly due to external radiation from ground and from consumption of contaminated food. The radiation exposure in the most contaminated areas was calculated on the basis of model assumptions and was found to be about 1 mSv during the first year after the accident. Using this model, the ingestion pathway was overestimated by at least a factor of two. This additional exposure decreased and is now less than 1 % on average; in the most contaminated areas, this is a few percent of the average natural radiation exposure.

    2011-01-01

    Background: The purpose of this study was to compare centralized reimbursement/coverage decision-making processes for health technologies in 23 European countries, according to: mandate, authority, structure, and policy options; mechanisms for identifying, selecting, and evaluating technologies; clinical and economic evidence expectations; committee composition, procedures, and factors considered; available conditional reimbursement options for promising new technologies; and the manufacturers’ roles in the process. Methods: A comprehensive review of publicly available information from peer-reviewed literature (using a variety of bibliographic databases) and gray literature (eg, working papers, committee reports, presentations, and government documents) was conducted. Policy experts in each of the 23 countries were also contacted. All information collected was reviewed by two independent researchers. Results: Most European countries have established centralized reimbursement systems for making decisions on health technologies. However, the scope of technologies considered, as well as processes for identifying, selecting, and reviewing them varies. All systems include an assessment of clinical evidence, compiled in accordance with their own guidelines or internationally recognized published ones. In addition, most systems require an economic evaluation. The quality of such information is typically assessed by content and methodological experts. Committees responsible for formulating recommendations or decisions are multidisciplinary. While criteria used by committees appear transparent, how they are operationalized during deliberations remains unclear. Increasingly, reimbursement systems are expressing interest in and/or implementing reimbursement policy options that extend beyond the traditional “yes,” “no,” or “yes with restrictions” options. Such options typically require greater involvement of manufacturers which, to date, has been limited

  18. Changes in the mantle transition zone from central Europe to the East European Craton as seen by receiver functions

    2012-04-01

    The depth to which lithospheric roots of cratons influence the surrounding mantle has important consequences for our understanding of the thermal structure of the mantle and its geodynamics. Still, this information is often not well constrained: previous studies of depth variations in mantle transition zone (MTZ) discontinuities beneath cratons led to variable results, depending on the craton under investigation. Here, we present evidence that the influence of the East European Craton extends into the MTZ. We study teleseismic P-receiver functions recorded at more than 400 stations across central and eastern Europe, from the Netherlands to Estonia. Using P-to-S converted waves, receiver functions yield relative travel times to the 410 km and 660 km discontinuities and are especially useful in mapping variations in MTZ thickness. The main data source in our study is the multinational PASSEQ experiment, which achieved the densest coverage with seismic stations yet in Poland and Lithuania by using about 200 temporary stations installed from 2006 to 2008. These recordings are supplemented by national and regional networks and broad-band data from older temporary deployments. The large data set allows us to image the MTZ across the Trans-European Suture Zone (TESZ), the western boundary of the East European Craton, in high resolution. We observe significantly advanced onset times, by as much as 2 s compared to standard Earth models and up to 3 s compared to the Central European Platform, for conversions from both MTZ discontinuities for locations within the craton. This effect is expected and due to the higher velocities in the mantle above the MTZ, e.g. the cratonic root. It gets even more pronounced when the opposing effect of variable crustal thickness (50 km and more within the craton in contrast to 30 to 35 km in central Europe) is considered. Additionally, the differential travel time between the two discontinuities is increased by 1 s beneath the craton, most

  19. A transportable mb(Lg) scale for central Europe and implications for low-magnitude Ms-mb discrimination

    NASA Astrophysics Data System (ADS)

    Patton, Howard J.; Schlittenhardt, Jörg

    2005-10-01

    We have extended the mb(Lg) method of Nuttli using root-mean-square (rms) amplitudes corrected for noise and a Δ-1 dependence for geometrical spreading. Lg waves recorded on the German Regional Seismic Network (GRSN) for earthquakes in south-central Europe were used to develop an mb(Lg) formula requiring a new calibration constant Crms to keep rms mb(Lg) on the same baseline as Nuttli's traditional formula based on 3rd-peak amplitudes. GRSN stations had to be calibrated for site terms and for Lg attenuation. Lateral variations in LgQ appear to be significant across the study area, and a regional Q model consisting of constant-Q partitions north, south and in the central Alps was developed using measurements based on interstation and two-event, single-station methods. When plotted against surface wave estimates of Mw, rms mb(Lg) measurements in central Europe are found to be consistent with Mw-mb(Lg) relationships for north America and southern Asia, thus supporting the transportability of our mb(Lg) formula. Frequency-wavenumber processing of Gräfenberg Array data enabled us to extract Rayleigh waves for small events, and regional Ms were measured using the Marshall and Basham formula. Our Ms-mb(Lg) relationship extends to Ms 2.5 and agrees well with observations in other regions including the western United States. The discrimination potential of Ms-mb(Lg) observations was examined under realistic monitoring conditions, where path corrections were inferred from earthquake data and applied uniformly to natural sources and explosions. Under these conditions, mb(Pn, P) are greater than mb(Lg) for large NTS explosions; however, Ms-mb scaling slopes are steeper for P waves than they are for Lg, and Ms-mb observations for NTS explosions converge near mb 4. Thus, allowing for measurement errors and additional uncertainty in mb(Pn) due to regional bias, there is little difference in the discrimination potential for Pn and Lg waves at small magnitudes. As such, a

    A land surface model s ability to simulate states (e.g., soil moisture) and fluxes (e.g., runoff) is limited by uncertainties in meteorological forcing and parameter inputs as well as inadequacies in model physics. In this study, anomalies of terrestrial water storage (TWS) observed by the Gravity Recovery and Climate Experiment (GRACE) satellite mission were assimilated into the NASA Catchment land surface model in western and central Europe for a 7-year period, using a previously developed ensemble Kalman smoother. GRACE data assimilation led to improved runoff correlations with gauge data in 17 out of 18 hydrological basins, even in basins smaller than the effective resolution of GRACE. Improvements in root zone soil moisture were less conclusive, partly due to the shortness of the in situ data record. In addition to improving temporal correlations, GRACE data assimilation also reduced increasing trends in simulated monthly TWS and runoff associated with increasing rates of precipitation. GRACE assimilated root zone soil moisture and TWS fields exhibited significant changes in their dryness rankings relative to those without data assimilation, suggesting that GRACE data assimilation could have a substantial impact on drought monitoring. Signals of drought in GRACE TWS correlated well with MODIS Normalized Difference Vegetation Index (NDVI) data in most areas. Although they detected the same droughts during warm seasons, drought signatures in GRACE derived TWS exhibited greater persistence than those in NDVI throughout all seasons, in part due to limitations associated with the seasonality of vegetation.

    Background Gastrointestinal disorders account for 7–10% of all consultations in primary care. General practitioners’ management of digestive disorders in Central and Eastern European countries is largely unknown. Aims To identify and compare variations in the self-perceived responsibilities of general practitioners in the management of digestive disorders in Central and Eastern Europe. Methods A cross-sectional survey of a randomized sample of primary care physicians from 9 countries was conducted. An anonymous questionnaire was sent via post to primary care doctors. Results We received 867 responses; the response rate was 28.9%. Over 70% of respondents reported familiarity with available guidelines for gastrointestinal diseases. For uninvestigated dyspepsia in patients under 45 years, the “test and treat” strategy was twice as popular as “test and scope”. The majority (59.8%) of family physicians would refer patients with rectal bleeding without alarm symptoms to a specialist (from 7.6% of doctors in Slovenia to 85.1% of doctors in Bulgaria; p<0.001). 93.4% of respondents declared their involvement in colorectal cancer screening. In the majority of countries, responding doctors most often reported that they order fecal occult blood tests. The exceptions were Estonia and Hungary, where the majority of family physicians referred patients to a specialist (p<0.001). Conclusions Physicians from Central and Eastern European countries understood the need for the use of guidelines for the care of patients with gastrointestinal problems, but there is broad variation between countries in their management. Numerous efforts should be undertaken to establish and implement international standards for digestive disorders’ management in general practice.

    Aim To evaluate Y-chromosomal diversity of the Moravian Valachs of the Czech Republic and compare them with a Czech population sample and other samples from Central and South-Eastern Europe, and to evaluate the effects of genetic isolation and sampling. Methods The first sample set of the Valachs consisted of 94 unrelated male donors from the Valach region in northeastern Czech Republic border-area. The second sample set of the Valachs consisted of 79 men who originated from 7 paternal lineages defined by surname. No close relatives were sampled. The third sample set consisted of 273 unrelated men from the whole of the Czech Republic and was used for comparison, as well as published data for other 27 populations. The total number of samples was 3244. Y-short tandem repeat (STR) markers were typed by standard methods using PowerPlex® Y System (Promega) and Yfiler® Amplification Kit (Applied Biosystems) kits. Y-chromosomal haplogroups were estimated from the haplotype information. Haplotype diversity and other intra- and inter-population statistics were computed. Results The Moravian Valachs showed a lower genetic variability of Y-STR markers than other Central European populations, resembling more to the isolated Balkan populations (Aromuns, Csango, Bulgarian, and Macedonian Roma) than the surrounding populations (Czechs, Slovaks, Poles, Saxons). We illustrated the effect of sampling on Valach paternal lineages, which includes reduction of discrimination capacity and variability inside Y-chromosomal haplogroups. Valach modal haplotype belongs to R1a haplogroup and it was not detected in the Czech population. Conclusion The Moravian Valachs display strong substructure and isolation in their Y chromosomal markers. They represent a unique Central European population model for population genetics.

    2010-03-01

    The INQUA Loess Commission expanded from its Central European base after the 1977 INQUA Congress. The first, furthest, and probably most successful expansion was the Western Pacific Working Group(WPWG). Co-operative loess research between China, Australia and New Zealand demonstrated the ideal working of a dedicated research group within the INQUA protocols. The WPWG functioned from 1978 to about 1988, a critical ten years during which China re-appeared on the world loess scene. The WPWG meeting in China in 1985 was a useful precursor to the INQUA Congress in Beijing in 1991. The main function of the WPWG turned out to be facilitating the return of China to the world of loess scholarship.

  12. Nitrogen and metals in two regions in Central Europe: significant differences in accumulation in mosses due to land use?

    2007-10-01

    The study was conducted to test the hypothesis that the regional variability of nitrogen (N) and metal accumulations in terrestrial ecosystems are due to historical and recent ways of landuse. To this end, two regions of Central Europe were selected for investigation: the Weser-Ems Region (WER) and the Euro Region Nissa (ERN). They were assumed to have land use-specific accumulation profiles. Thus, the metal and N accumulations in both regions were examined by means of geostatistically based comparative moss analysis. The sampling and chemical analysis of mosses were conducted in accordance with the convenient guidelines and methods, respectively. The spatial representativity of the sampling sites was computed by means of a land classification which was calculated for Europe by means of classification trees and GIS-techniques. The differences of deposition loads were tested for statistical significance with regard to time and space. The measurement values corroborated the decline of metal accumulation observed since the beginning of the European Metals in Mosses Surveys in 1990. The metal loads of the mosses in the ERN exceeded those in the WER significantly. The opposite holds true for the N concentrations: those in the WER were significantly higher than those in the ERN. The reduction of emissions from power plants, factories and houses was strongly correlated with the decline of deposition and bioaccumulation of metals. As proved by the European Metals in Mosses Surveys, this tendency is due to successful environmental policies. But no such success could be verified by monitoring the accumulation of N in mosses.

  13. The cardiovascular risk factors of the Roma (Gypsies) people in Central-Eastern Europe: a review of the published literature

    PubMed Central

    Dobranici, M; Buzea, A; Popescu, R

    2012-01-01

    Background: Estimated number of the Roma people in central-eastern Europe cannot be precisely appreciated, but official data suggest that in the 2004 they were approximately 4.2 million. At this time, there are few available data about the health status of the Roma people, mostly assessing genetic and infectious diseases, which reflect poverty, overcrowding, and lack of education. There is even less data regarding non–communicable and chronic diseases, especially cardiovascular diseases. Methods: We searched the published literature on the cardiovascular risk factors in Roma people using PubMed from January 2000 to July 2011. The searching criteria were: (1) randomized, prospective observational, retrospective and meta-analysis; (2) adult patients with cardiac diseases or cardiovascular risk factors (3) data available for cardiovascular patients. Search terms included dyslipidemia, obesity, tobacco, hypertension, and diabetes mellitus. Results: Twenty-five studies were identified. Approximately 75% of them were related to just four countries: Slovakia, Croatia, Czech Republic, and Serbia. This paper is a review based on existing literature concerning classical risk factors in Roma people with emphasis on their ethnical features. Despite limited data, the results showed that this ethnicity has the incriminated risk factors more frequently than the majority and consequently a higher cardiovascular morbidity rate. Conclusions: Quantification of the cardiovascular risk factor and their implication in the shortening of life expectancy in Roma population was a provocation due to a paucity of reliable data. At this time, we should pay more attention on the Roma health issues and the cultural concerns that might affect them in the context of borderless Europe. PMID:23390466

    2013-01-01

    Countries from South-East Europe (SEE), Central and Eastern Europe (CEE) and Newly Independent States (NIS) are in the process of harmonization with European environmental noise legislation. However, research work on noise and health was performed in some countries independently of harmonization process of adoption and implementation of legislation for environmental noise. Aim of this review is to summarize available evidence for noise induced sleep disturbance in population of CEE, SEE and NIS countries and to give directions for further research work in this field. After a systematic search through accessible electronic databases, conference proceedings, PhD thesis, national reports and scientific journals in English and non-English language, we decided to include six papers and one PhD thesis in this review: One paper from former Yugoslavia, one paper from Slovakia, one paper from Lithuania, two papers from Serbia and one paper, as also one PhD thesis from The Former Yugoslav Republic of Macedonia. Noise exposure assessment focused on road traffic noise was mainly performed with objective noise measurements, but also with noise mapping in case of Lithuanian study. Sleep disturbance was assessed with the questionnaire based surveys and was assumed from dose-effect relationship between night-time noise indicator (Lnight ) for road traffic noise and sleep disturbance (for Lithuanian study). Although research evidence on noise and sleep disturbance show to be sufficient for establishing dose response curves for sleep disturbance in countries where studies were performed, further research is needed with particular attention to vulnerable groups, other noise sources, development of laboratory research work and common methodology in assessment of burden of diseases from environmental noise.

  15. Spatial variations of earthquake occurrence and coseismic deformation in the Upper Rhine Graben, Central Europe

    Seismic activity in the densely populated Upper Rhine Graben (URG) is an aspect in the public, political, and industrial decision making process. The spatial analysis of magnitude-frequency distributions provides valuable information about local seismicity patterns and regional seismic hazard assessment and can be used also as a proxy for coseismic deformation to explore the seismo-tectonic setting of the URG. We combine five instrumental and one historic earthquake bulletins to obtain for the first time a consistent database for events with local magnitudes ML ≥ 2.0 in the whole URG and use it for the determination of magnitude frequencies. The data processing results in a dataset with 274 Poisson distributed instrumentally recorded earthquakes within the URG between 01/1971 and 02/2012 and 34 historic events since the year 1250. Our analysis reveals significant b-value variations along the URG that allow us to differentiate four distinct sections (I-IV) with significant differences in earthquake magnitude distributions: I: Basel region in the Swiss-France-German border region (b = 0.83), II: region between Mulhouse and Freiburg in the southern URG (b = 1.42), III: central URG (b = 0.93), and IV: northern URG (b = 1.06). High b-values and thus a relatively low amount of high magnitude events in the Freiburg section are possibly a consequence of strongly segmented, small-scale structures that are not able to accumulate high stresses. We use the obtained magnitude-frequency distributions and representative source mechanisms for each section to determine coseismic displacement rates. A maximum horizontal displacement rate of 41 μm/a around Basel is found whereas only 8 μm/a are derived for the central and northern URG. A comparison with geodetic and geological constraints implies that the coseismic displacement rates cover less than 10% of the overall displacement rates, suggesting a high amount of aseismic deformation in the URG.

  16. A possible central mechanism in autism spectrum disorders, part 1.

    Blaylock, Russell L

    2008-01-01

    The autism spectrum disorders (ASD) are a group of related neurodevelopmental disorders that have been increasing in incidence since the 1980s. Despite a considerable amount of data being collected from cases, a central mechanism has not been offered. A careful review of ASD cases discloses a number of events that adhere to an immunoexcitotoxic mechanism. This mechanism explains the link between excessive vaccination, use of aluminum and ethylmercury as vaccine adjuvants, food allergies, gut dysbiosis, and abnormal formation of the developing brain. It has now been shown that chronic microglial activation is present in autistic brains from age 5 years to age 44 years. A considerable amount of evidence, both experimental and clinical, indicates that repeated microglial activation can initiate priming of the microglia and that subsequent stimulation can produce an exaggerated microglial response that can be prolonged. It is also known that one phenotypic form of microglia activation can result in an outpouring of neurotoxic levels of the excitotoxins, glutamate and quinolinic acid. Studies have shown that careful control of brain glutamate levels is essential to brain pathway development and that excesses can result in arrest of neural migration, as well as dendritic and synaptic loss. It has also been shown that certain cytokines, such as TNF-alpha, can, via its receptor, interact with glutamate receptors to enhance the neurotoxic reaction. To describe this interaction I have coined the term immunoexcitotoxicity, which is described in this article.

    Metallurgical characterization of a sword blade fragments dating from the second half of the 15th century found in central Slovenia was performed in order to determine its chemical composition, microstructure, microhardness, and to obtain insight into the methods of manufacture of a late-medieval Messer sword. As the artefact was broken, examinations were limited to six very small fragments that were allowed to be removed from the cutting edge, core and the back of the blade. Light optical microscopy, scanning electron microscopy, energy dispersive X-ray spectroscopy, energy dispersive X-ray fluorescence spectrometry, differential scanning calorimetry, thermodynamics approach and Vickers micro-hardness tests were employed to analyze the microstructure and mechanical properties. The results show that the sword was manufactured from a single wrought iron billet. The surface of the sword was carburized. No evidence of quenching was found. The ferritic microstructure is concentrated in the core, and the pearlitic in the outer layer of the blade. All metal fragments contained non-metallic inclusions that were derived mostly from slag and some from hammer scale. - Highlights: • A metallurgical characterization of a medieval sword blade has been performed. • The carbon content decreased from the surface to the core of the blade. • The dominant microstructure in the outer layer is pearlite and in the core is ferrite. • The presence of lump shaped and elongated non-metallic inclusions was observed. • The sword was manufactured from a single wrought iron billet.

  18. The inability to pay for health services in Central and Eastern Europe: evidence from six countries

    Background: Out-of-pocket payments for health services constitute a major financial burden for patients in Central and Eastern European (CEE) countries. Individuals who are unable to pay use different coping strategies (e.g. borrowing money or foregoing service utilization), which can have negative consequences on their health and social welfare. This article explores patients’ inability to pay for outpatient and hospital services in six CEE countries: Bulgaria, Hungary, Lithuania, Poland, Romania and Ukraine. Methods: The analysis is based on quantitative data collected in 2010 in nationally representative surveys. Two indicators of inability to pay were considered: the need to borrow money or sell assets and foregoing service utilization. Statistical analyses were applied to investigate associations between the indicators of inability to pay and individual characteristics. Results: Patient payments are most common in Bulgaria, Ukraine, Romania and Lithuania and often include informal payments. Romanian and, particularly, Ukrainian patients most often face difficulties to pay for health services (with approximately 40% of Ukrainian payers borrowing money or selling assets to cover hospital payments and approximately 60% of respondents who need care foregoing services). Inability to pay mainly affects those with poor health and low incomes. Conclusion: Widespread patient payments constitute a major financial barrier to health service use in CEE. There is a need to formalize them where they are informal and to take measures to protect vulnerable population groups, especially those with limited possibilities to deal with payment difficulties.

  19. Neuroscience in Nazi Europe part I: eugenics, human experimentation, and mass murder.

    Zeidman, Lawrence A

    2011-09-01

    The Nazi regime in Germany from 1933 to 1945 waged a veritable war throughout Europe to eliminate neurologic disease from the gene pool. Fueled by eugenic policies on racial hygiene, the Nazis first undertook a sterilization campaign against "mental defectives," which included neurologic patients with epilepsy and other disorders, as well as psychiatric patients. From 1939-41 the Nazis instead resorted to "euthanasia" of many of the same patients. Some neuroscientists were collaborators in this program, using patients for research, or using extracted brains following their murder. Other reviews have focused on Hallervorden, Spatz, Schaltenbrand, Scherer, and Gross, but in this review the focus is on neuroscientists not well described in the neurology literature, including Scholz, Ostertag, Schneider, Nachtsheim, and von Weizsäcker. Only by understanding the actions of neuroscientists during this dark period can we learn from the slippery slope down which they traveled, and prevent history from repeating itself.

    Marginalised Roma communities in European countries live in substandard housing conditions the improvement of which has been one of the major issues of the Decade of Roma Inclusion, the ongoing intergovernmental European Roma programme. The paper presents EU-funded health impact assessments of national Roma housing policies and programmes in 3 Central and Eastern European countries in light of the evaluation of a completed local project in a fourth CEE country so as to compare predicted effects to observed ones. Housing was predicted to have beneficial health effects by improving indoor and outdoor conditions, access to services, and socioeconomic conditions. Negative impacts were predicted only in terms of maintenance expenses and housing tenure. However, observed impacts of the completed local project did not fully support predictions especially in terms of social networks, satisfaction with housing and neighbourhood, and inhabitant safety. In order to improve the predictive value of HIA, more evidence should be produced by the careful evaluation of locally implemented housing projects. In addition, current evidence is in favour of planning Roma housing projects at the local rather than at the national level in alignment with the principle of subsidiarity. - Highlights: Black-Right-Pointing-Pointer Predictive validity of HIA of national Roma housing policies - in light of current evidence - is low. Black-Right-Pointing-Pointer Implemented housing projects should be comprehensively evaluated to improve reliability of HIA. Black-Right-Pointing-Pointer Roma housing projects should be planned at the local rather than at the national level. Black-Right-Pointing-Pointer HIA should be used to plan Roma housing projects at the local level.

  1. Phenology in central Europe - differences and trends of spring phenophases in urban and rural areas

    Roetzer, T.; Wittenzeller, Markus; Haeckel, Hans; Nekovar, Jiri

    In order to examine the impacts of both large-scale and small-scale climate changes (urban climate effect) on the development of plants, long-term observations of four spring phenophases from ten central European regions (Hamburg, Berlin, Cologne, Frankfurt, Munich, Prague, Vienna, Zurich, Basle and Chur) were analysed. The objective of this study was to identify and compare the differences in the starting dates of the pre-spring phenophases, the beginning of flowering of the snowdrop (Galanthus nivalis) and forsythia (Forsythia sp.), and of the full-spring phenophases, the beginning of flowering of the sweet cherry (Prunus avium) and apple (Malus domestica), in urban and rural areas. The results indicate that, despite regional differences, in nearly all cases the species studied flower earlier in urbanised areas than in the corresponding rural areas. The forcing in urban areas was about 4 days for the pre-spring phenophases and about 2 days for the full-spring phenophases. The analysis of trends for the period from 1951 to 1995 showed tendencies towards an earlier flowering in all regions, but only 22% were significant at the 5% level. The trends for the period from 1980 to 1995 were much stronger for all regions and phases: the pre-spring phenophases on average became earlier by 13.9 days/decade in the urban areas and 15.3 days/decade in the rural areas, while the full-spring phenophases were 6.7 days earlier/decade in the urban areas and 9.1 days/decade earlier in the rural areas. Thus rural areas showed a higher trend towards an earlier flowering than did urban areas for the period from 1980 to 1995. However, these trends, especially for the pre-spring phenophases, turned out to be extremely variable.

    The pattern of microhabitat preferences of Ukrainian brook lamprey Eudontomyzon mariae ammocoetes was examined in two rivers of central Poland: the Pilica River (the Vistula River basin) and the Grabia River (the Odra River basin). A comparison of abiotic factors of the rivers revealed differences in water speed and principal components: PC1 (determining gradient from decreasing medium sand to the increasing share of three fractions of gravel), PC2 (a gradient from the declining share of very coarse and coarse sand fractions to the growing content of fine sand) and PC3 (correlated with an increasing proportion of silt). The sites did not differ significantly in terms of water depth. Relative abundance and frequency of ammocoete occurrence in the Grabia River were higher than in the Pilica River. Only speed, PC1 and PC2 made a significant contribution to the prediction of larval occurrence. Eudontomyzon mariae larvae preferred substrata with a reduced amount of medium sand and increased content of gravel (PC1) as well as with a lower content of coarse sand and higher proportion of fine-grained sand (PC2). The ammocoetes also preferred areas with a water speed of 0·2 m s(-1) but avoided speeds ≥ 0·6 m s(-1). The abundance of E. mariae was affected by water speed, as well as by all PCs. The mean ± s.e. optimal current speed was 0·265 ± 0·007 m s(-1), while abundance decreased with increasing amounts of gravel (PC1) and increased with increasing amounts of fine sand and silt in the bottom substratum (PC2 and PC3). Comparison of ammocoete microhabitat use in the Pilica and Grabia Rivers showed the lack of differences in distribution in the preferred values of current speed, PC1 and PC2.

    We present a new database of surface wave group and phase-velocity dispersion curves derived from seismic ambient noise, cross-correlating continuous seismic recordings from the Swiss Network, the German Regional Seismological Network (GRSN), the Italian national broad-band network operated by the Istituto Nazionale di Geosica e Vulcanologia (INGV). To increase the aperture of the station array, additional measurements from the Mediterranean Very Broad-band Seismographic Network (MedNet), the Austrian Central Institute for Meteorology and Geodynamics (ZAMG), the French, Bulgarian, Hungarian, Romanian and Greek stations obtained through Orfeus are also included. The ambient noise, we are using to assemble our database, was recorded at the above-mentioned stations between 2006 January and 2006 December. Correlating continuous signal recorded at pairs of stations, allows to extract coherent surface wave signal travelling between the two stations. Usually the ambient-noise cross-correlation technique allows to have informations at periods of 30 s or shorter. By expanding the database of noise correlations, we seek to increase the resolution of the central Europe crustal model. We invert the resulting data sets of group and phase velocities associated with 8-35 s Rayleigh waves, to determine 2-D group and phase-velocity maps of the European region. Inversions are conducted by means of a 2-D linearized tomographic inversion algorithm. The generally good agreement of our models with previous studies and good correlation of well-resolved velocity anomalies with geological features, such as sedimentary basins, crustal roots and mountain ranges, documents the effectiveness of our approach.

    For the first time outside sub-Saharan Africa, a lineage 2 West Nile virus (WNV) emerged in Hungary in 2004. It caused sporadic cases of encephalitis in goshawks (Accipiter gentilis), other predatory birds, and in mammals. As a consequence, a surveillance program was initiated in Hungary and in Austria, which included virological, molecular, serological and epidemiological investigations in human beings, birds, horses, and mosquitoes. The virus strain became endemic to Hungary, however only sporadic cases of infections were observed between 2004 and 2007. Unexpectedly, explosive spread of the virus was noted in 2008, when neuroinvasive West Nile disease (WND) was diagnosed all over Hungary in dead goshawks and other birds of prey (n=25), in horses (n=12), and humans (n=22). At the same time this virus also spread to the eastern part of Austria, where it was detected in dead wild birds (n=8). In 2009, recurrent WND outbreaks were observed in Hungary and Austria, in wild birds, horses, and humans in the same areas. Virus isolates of both years exhibited closest genetic relationship to the lineage 2 WNV strain which emerged in 2004. As we know today, the explosive spread of the lineage 2 WNV in 2008 described here remained not restricted to Hungary and Austria, but this virus dispersed further to the south to various Balkan states and reached northern Greece, where it caused the devastating neuroinvasive WND outbreak in humans in 2010.

    This study investigates the low-frequency (interannual and longer period) variability in three hydroclimatic records from east Central Europe. Two of these records consist of climate proxies derived from oak-tree rings in Bakta forest, and Balaton Highlands in Hungary, for the time interval 1783-2003. The third record consists of homogenized instrumental precipitation data from Budapest, Hungary, from 1842 to 2003. Using wavelet analysis, the three time series are analyzed and compared with one another. It is found that all three time series exhibit strong interannual variability at the 2-4 years timescales, and these variations occur intermittently throughout the length of each record. Significant variability is also observed in all the records at decadal timescales, but these variations persist for only two to three cycles. Wavelet coherence among the various time series is used to explore their time-varying correlation. The results reveal significant coherence at the 2-4 years band. At these timescales, the climatic variations are correlated to the tree-ring signal over different time intervals with changing phase. Increased (decreased) contribution of large-scale stratiform precipitation offers a potential explanation for enhanced (faded) coherence at the interannual timescale. Strong coherence was also observed occasionally at decadal timescales, however these coherences did not appear uniformly. These results reinforce the earlier assertion that neither the strength nor the rank of the similarity of the local hydroclimate signals is stable throughout the past two centuries.

    The aim of this study was to explore the species diversity of Trichoderma obtained from samples of wood collected in the forests of the Gorce Mountains (location A), Karkonosze Mountains (location B) and Tatra Mountains (location C) in Central Europe and to examine the cellulolytic and xylanolytic activity of these species as an expression of their probable role in wood decay processes. The present study has led to the identification of the following species and species complex: Trichoderma atroviride P. Karst., Trichoderma citrinoviride Bissett, Trichoderma cremeum P. Chaverri & Samuels, Trichoderma gamsii Samuels & Druzhin., Trichoderma harzianum complex, Trichoderma koningii Oudem., Trichoderma koningiopsis Samuels, C. Suárez & H.C. Evans, Trichoderma longibrachiatum Rifai, Trichoderma longipile Bissett, Trichoderma sp. (Hypocrea parapilulifera B.S. Lu, Druzhin. & Samuels), Trichoderma viride Schumach. and Trichoderma viridescens complex. Among them, T. viride was observed as the most abundant species (53 % of all isolates) in all the investigated locations. The Shannon's biodiversity index (H), evenness (E), and the Simpson's biodiversity index (D) calculations for each location showed that the highest species diversity and evenness were recorded for location A-Gorce Mountains (H' = 1.71, E = 0.82, D = 0.79). The preliminary screening of 119 Trichoderma strains for cellulolytic and xylanolytic activity showed the real potential of all Trichoderma species originating from wood with decay symptoms to produce cellulases and xylanases-the key enzymes in plant cell wall degradation.

    A Bayesian inversion approach was used to retrieve temporally and spatially resolved N2O fluxes for western and central Europe using in-situ atmospheric observations from the tall tower site at Ochsenkopf, Germany (50°01' N, 11°48' E). For atmospheric transport, the STILT (Stochastic Time-Inverted Lagrangian Transport) model was employed, which was driven with ECMWF analysis and short term forecast fields. The influence of temporal aggregation error, as well as the choice of spatial and temporal correlation scale length, on the retrieval was investigated using a synthetic dataset consisting of mixing ratios generated for the Ochsenkopf site. We found that if the aggregation error is ignored, then a significant bias error in the retrieved fluxes ensues. However, by estimating this error and projecting it into the observation space, it was possible to avoid bias errors in the retrieved fluxes. Using the real observations from the Ochsenkopf site, N2O fluxes were retrieved every 7 days for 2007 at 2 by 2 degrees spatial resolution. Emissions of N2O were strongest during the summer and autumn months, with peak emissions in August and September, while the regions of Benelux and northern United Kingdom had strongest annual mean emissions.

    2010-09-01

    Daily precipitation totals and daily mean temperature from Central Europe, from the period 1951-2006 have been analyzed. The drought was described using de Martonne, Ped and SPI indices. Aridity index defined by de Martonne Mi (1926) is computed as: Mi= 12Ri/(Ti+10), where Ri is the monthly precipitation amount and Ti is the monthly mean air temperature. The Ped index is defined as Pi=(Ti-Tm)/σT -(Ri-Rm)/σR , where Tm and Rm are mean monthly (seasonal) temperature and precipitation, respectively, and σT and σR are standard deviations of monthly (seasonal) temperature and precipitation, respectively. According to McKee et al. (1993), the SPI is defined on each of the time scales as the difference between precipitation on the time series (Ri) and the mean value (Rm), divided by the standard deviation (σR). This definition assumes that the data fit the normal distribution, but because it is rarely true for precipitation data the data were usually transformed to standard normal distribution. Different distributions have been used to precipitation time series on monthly and seasonal scale. The Kolmogorov-Smirnov test was used to evaluate the goodness of fit. The relations between temporal series of different indices were analyzed using Pearson's and Spearman's correlation coefficients. Also the trends were analyzed on the basis of both minimum square fit of polynomials and Mann-Kendall test. Spatial distribution of trends was analyzed.

  12. Susceptibility to acidic precipitation contributes to the decline of the terricolous lichens Cetraria aculeata and Cetraria islandica in central Europe.

    The effective quantum yield of photochemical energy conversion in photosystem II (Phi2) was shown to be reduced in the terricolous lichens Cetraria aculeata and Cetraria islandica by short-term exposure to aqueous SO2 at pH values occurring in the precipitation of areas with high SO2 pollution. Significant reduction of Phi2 was found at pHcentral Europe. In C. islandica, but not in C. aculeata, thalli with the natural content of lichen substances were more tolerant to SO2 than thalli where the extracellular lichen substances were extracted before the experiment. This supports published results that the depsidone fumarprotocetraric acid, a major lichen substance of C. islandica, increases the pollution tolerance in lichens.

    2016-04-01

    During an investigation for potential arboviruses present in mosquitoes in Hungary (Central Europe) three highly similar virus strains of a novel rhabdovirus (family Rhabdoviridae) called Riverside virus (RISV, KU248085-KU248087) were detected and genetically characterized from Ochlerotatus sp. mosquito pools collected from 3 geographical locations using viral metagenomic and RT-PCR methods. The ssRNA(-) genome of RISVs follows the general genome layout of rhabdoviruses (3'-N-P-M-G-L-5') with two alternatives, small ORFs in the P and G genes (Px and Gx). The genome of RISVs contains some unusual features such as the large P proteins, the short M proteins with the absence of N-terminal region together with the undetectable "Late budding" motif and the overlap of P and M genes. The unusually long 3' UTRs of the M genes of RISVs probably contain a remnant transcription termination signal which is suggesting the presence of an ancestral gene. The phylogenetic analysis and sequence comparisons show that the closest known relative of RISVs is the recently identified partially sequenced mosquito-borne rhabdovirus, North Creek virus (NOCRV), from Australia. The RISVs and NOCRV form a distinct, basally rooted lineage in the dimarhabdovirus supergroup. The host species range of RISVs is currently unknown, although the presence of these viruses especially in Ochlerotatus sp. mosquitoes which are known to be fierce biting pests of humans and warm-blooded animals and abundant and widespread in Hungary could hold some potential medical and/or veterinary risks.

    Background Despite the attention the situation of the Roma in Central and Eastern Europe has received in the context of European Union enlargement, research on their access to health services is very limited, in particular with regard to child health services. Methods 50 qualitative in-depth interviews with users, providers and policy-makers concerned with child health services in Bulgaria, conducted in two villages, one town of 70,000 inhabitants, and the capital Sofia. Results Our findings provide important empirical evidence on the range of barriers Roma children face when accessing health services. Among the most important barriers are poverty, administrative and geographical obstacles, low levels of parental education, and lack of ways to accommodate the cultural, linguistic and religious specifics of this population group. Conclusion Our research illustrates the complexity of the problems the Roma face. Access to health care cannot be discussed in isolation from other problems this population group experiences, such as poverty, restricted access to education, and social exclusion. PMID:19566936

  15. Public health research support through the European structural funds in central and eastern Europe and the Mediterranean

    Background Public health research provides evidence for practice across fields including health care, health promotion and health surveillance. Levels of public health research vary markedly across European Union (EU) countries, and are lowest in the EU's new member states (in Central and Eastern Europe and the Mediterranean). However, these countries now receive most of the EU's Structural Funds, some of which are allocated to research. Methods STEPS, an EU-funded study, sought to assess support for public health research at national and European levels. To identify support through the Structural funds, STEPS drew information from country respondents and internet searches for all twelve EU new member states. Results The EU allocates annually around €7 billion through the Structural Funds for member states' own use on research. These funds can cover infrastructure, academic employment, and direct research grants. The programmes emphasise links to business. Support for health research includes major projects in biosciences, but direct support for public health research was found in only three countries - Cyprus, Latvia and Lithuania. Conclusions Public health research is not prioritised in the EU's Structural Funds programme in comparison with biomedicine. For the research dimension of the new European programme for Structural Funds 2014-2002, ministries of health should propose public health research to strengthen the evidence-base for European public health policy and practice.

  1. Social security reform in Central and Eastern Europe: variations on a Latin American theme.

    PubMed

    Kritzer, B E

    After Chile reformed its social security system in 1981, several other Latin American countries and certain Central and Eastern European (CEE) countries implemented the Chilean model, with some variations: either a single- or multitier system, or with a period of transition to take care of those in the labor force at the time of the change. The single-tier version consists of individual accounts in pension fund management companies. Multi-tier systems retain some form of public program and add mandatory individual accounts. Most of the CEE countries did not want to incur the high transition costs associated with the Chilean model. The switch to a market economy had already strained their economies. Also, the countries' desire to adopt the European Union's Euro as their currency--a move that required a specific debt ceiling--limited the amount of additional debt they could incur. This article describes the CEE reforms and makes some comparisons with the Latin American experience. Most of the CEE countries have chosen a mixed system and have restructured the pay-as-you-go (PAYGO) tier, while the Latin American countries have both single- and multi-tier systems. Some CEE countries have set up notional defined contribution (NDC) schemes for the PAYGO tier in which each insured person has a hypothetical account made up of all contributions during his or her working life. Survivors and disability programs in CEE have remained in the public tier, but in most of the Latin American programs the insured must purchase a separate insurance policy. Issues common to both regions include: Administrative costs are high and competition is keen, which has led to consolidation and mergers among the companies and a large market share controlled by a few companies. Benefits are proportionately lower for women than for men. A large, informal sector is not covered by social security. This sector is apparently much larger in Latin America than in the CEE countries. Issues that are unique

  2. Visible and Infrared Wavefront Sensing detectors review in Europe - part I

    Feautrier, Philippe; Gach, Jean-luc

    2013-12-01

    The purpose of this review is to give an overview of the state of the art wavefront sensor detectors developments held in Europe for the last decade. A major breakthrough has been achieved with the development by e2v technologies of the CCD220 between 2004 and 2012. Another major breakthrough is currently achieved with the very successful development of fast low noise infrared arrays called RAPID. The astonishing results of this device will be showed for the first time in an international conference at AO4ELT3.The CCD220, a 240x240 pixels 8 outputs EMCCD (CCD with internal multiplication), offers less than 0.2 e readout noise at a frame rate of 1500 Hz with negligible dark current. The OCAM2 camera is the commercial product that drives this advanced device. This system, commercialized by First Light Imaging, is quickly described in this paper. An upgrade of OCAM2 is currently developed to boost its frame rate to 2 kHz, opening the window of XAO wavefront sensing for the ELT using 4 synchronized cameras and pyramid wavefront sensing. This upgrade and the results obtained are described extensively elsewhere in this conference (Gach et al).Since this major success, new detector developments started in Europe. The NGSD CMOS device is fully dedicated to Natural and Laser Guide Star AO for the E-ELT with ESO involvement. The spot elongation from a LGS Shack Hartman wavefront sensor necessitates an increase of the pixel format. The NGSD will be a 880x840 pixels CMOS detector with a readout noise of 3 e (goal 1e) at 700 Hz frame rate. New technologies will be developed for that purpose: advanced CMOS pixel architecture, CMOS back thinned and back illuminated device for very high QE, full digital outputs with signal digital conversion on chip. This innovative device will be used on the European ELT but also interests potentially all giant telescopes.Additional developments also started in 2009 for wavefront sensing in the infrared based on a new technological breakthrough

  3. The 2014-2015 earthquake series in the northern Upper Rhine Graben, Central Europe

    2016-05-01

    Since March 2014, an unusually large amount of earthquakes occur southeast of the city of Darmstadt in the northern Upper Rhine Graben. During the period, until April 2015, we have recorded 356 earthquakes with magnitudes ranging from ML = -0.6 to 4.2. We identified two source clusters separated laterally by about 5 km. The hypocentres within these clusters are aligned vertically extending over a depth range from 1 to 8 km with a lateral extent of about 1 to 2 km. Focal mechanisms show left-lateral strike-slip movements; b values are changing with time between b = 0.6 and b = 0.9. This is the first time in almost 150 years that such high earthquake rates have been observed in the region. Historical accounts dating back to the nineteenth century report of over 2000 felt earthquakes over a time span from 1869 to 1871. From these, maximum intensities of VII have been estimated. Other seismic activities in the region were reported in the 1970s. The observations of the 2014-2015 earthquake series do not completely match a typical main shock-aftershock sequence or a typical earthquake swarm. Especially the activity at the beginning of the earthquake series may be considered as a mixture of a main shock-aftershock sequence and a short-lasting swarm event. Whether or not the time gap between the current seismic activity, which actually takes place at the same locations as parts of the seismic swarm in 1869-1871, and the seismic activity in the nineteenth century or the seismic activity in the 1970s can be interpreted as a seismic cycle remains unclear.

  4. Alchemical poetry in medieval and early modern Europe: a preliminary survey and synthesis. Part I--Preliminary survey.

    PubMed

    Kahn, Didier

    2010-11-01

    This article provides a preliminary description of medieval and early modern alchemical poetry composed in Latin and in the principal vernacular languages of western Europe. It aims to distinguish the various genres in which this poetry flourished, and to identify the most representative aspects of each cultural epoch by considering the medieval and early modern periods in turn. Such a distinction (always somewhat artificial) between two broad historical periods may be justified by the appearance of new cultural phenomena that profoundly modified the character of early modern alchemical poetry: the ever-increasing importance of the prisca theologia, the alchemical interpretation of ancient mythology, and the rise of neo-Latin humanist poetry. Although early modern alchemy was marked by the appearance of new doctrines (notably the alchemical spiritus mundi and Paracelsianism), alchemical poetry was only superficially modified by criteria of a scientific nature, which therefore appear to be of lesser importance. This study falls into two parts. Part I provides a descriptive survey of extant poetry, and in Part II the results of the survey are analysed in order to highlight such distinctive features as the function of alchemical poetry, the influence of the book market on its evolution, its doctrinal content, and the question of whether any theory of alchemical poetry ever emerged. Part II is accompanied by an index of the authors and works cited in both parts. PMID:21465995

  5. Fireball observations in central Europe and western Australia: instruments, methods, and results

    2012-01-01

    Penetration of larger meteoroids through the atmosphere which gives rise to spectacular luminous events - fireballs or even superbolides - is of the greatest interest. Their registrations, especially photographic and newly also photoelectric recordings, provide excellent means to examine physical properties as well as the temporal and spatial distribution of extraterrestrial matter in near-Earth space. The most efficient tools for registration of these very scarce events are the fireball networks: systems covering large areas of the Earth's surface, with multiple camera stations designed to image a large fraction of the night sky. Such camera networks for fireball observations have been set up in several nations at various times in the past (European Fireball Network (EN) in the Czech Republic, Germany, Austria, and Slovakia; the Prairie Network in the USA; and the Meteorite Observation and Recovery Project (MORP) in Canada). Of these networks, only the European fireball network is still in operation, and this continuously since it was started up, but recently new networks were established in South-West Australia and in Ontario, Canada. The two main scientific aims of all these programs remain the same as in the very beginning - first, to constrain the flux of extraterrestrial material to the Earth over a range of masses, and second, to provide a statistically significant group of meteorites with accurate orbits. This contribution was focused on the current work and some particular recent results from the European Fireball Network, especially from its Czech part (current status is described, for example, by Spurny et al., 2006) and from the Desert Fireball Network in the Nullarbor Plains of South-West Australia (Bland, 2004; Spurny et al., 2012; and Bland et al., 2012). The mode of operation of both networks and the analysis methods used were described in detail and illustrated by some examples. Similarly, the most important recent results, especially from the

    Beginning in 1997, Central Europe between the Baltic and Adriatic Seas, has been covered by an unprecedented network of seismic refraction experiments POLONAISE'97, CELEBRATION 2000, ALP 2002, and SUDETES 2003, have only been possible due to a massive international consortium consisted of more than 30 institutions from 16 countries in Europe and North America. The majority of recording instruments was provided by the IRIS/PASSCAL Instrument Center and the University of Texas at El Paso (USA), and several other countries also provided instrumentation. Total length of seismic profiles in all experiments is about 20,000 km. The main results of these experiments are: 1) the delineation of the deep structure of the southwestern margin of the East European Craton (southern Baltica) and its relationship to younger terranes; delineation of the major terranes and crustal blocks in the Trans European Suture Zone; determination of the structural framework of the Pannonian basin; elucidation of the deep structure and evolution of the Western Carpathian Mountains and Eastern Alps; determination of the structural relationships between the structural elements of the Bohemian massif and adjacent features; construction of 3-D models of the lithospheric structure; and evaluation and develop geodynamic models for the tectonic evolution of the region.

    Using statistical relationships between the composition of precipitation at eight long-term monitoring stations and emission rates of sulphur (S) and nitrogen (N) compounds, as well as industrial dust in the Czech Republic and Slovakia (Central Europe), we modelled historic pH and concentrations of sulphate (SO4(2-)), nitrate (NO3(-)), ammonium (NH4(+)), chloride (Cl(-)), base cations (BC), and bicarbonate (HCO3(-)) in bulk precipitation from 1850 to 2013. Our model suggests that concentrations of SO4(2-), NO3(-), and HCO3(-) were similar (11-16 μeq l(-1)) in 1850. Cations were dominated by NH4(+) and BC (24-27 μeq l(-1)) and precipitation pH was >5.6. The carbonate buffering system was depleted around 1920 and precipitation further acidified at an exponential rate until the 1980s, when concentrations of SO4(2-), NO3(-), Cl(-), NH4(+) and BC reached maxima of 126, 55, 16, 76, and 57 μeq l(-1), respectively, and pH decreased to 4.2. Dust emissions from industrial sources were an important source of BC. Without their contribution, pH would have decreased to 4.0 in the 1980s, and the carbonate buffering system would have been depleted already in the 1870s. Since the late 1980s, concentrations of strong acid anions and BC have decreased by 46-81% (i.e. more than in Europe on average) due to a 53-93% reduction in regional emissions of S and N compounds and dust from industrial and agricultural sources. The present composition of precipitation is similar to the late 19th century, except for NO3(-) concentrations, which are similar to those during 1926-1950. Precipitation pH now exceeds 5.0, the carbonate buffering system has been re-established, and HCO3(-) has again become (after almost a century) a significant component of precipitation chemistry.

    Pb isotope ratios and Pb concentrations of well-dated sediments of Lake Constance, Central Europe have been analyzed using thermal ion mass spectrometry. Sequential extraction studies indicated isotope homogeneity of the leachable Pb components within the investigated layers. Since the middle of the 19th century a significant anthropogenic Pb component appeared in the lake sediments, and rapidly approaches concentration levels similar to that of the geogenic Pb background (20 ppm) at the beginning of the 20th century. Anthropogenic Pb was predominantly transferred to the lake sediments via the atmosphere. Pb sources were coal combustion, industrial ore processing and leaded gasoline. The flux of a fluvial Pb component to the lake sediments, additive to atmospheric Pb deposition, peaked in about 1960. This flux is attributed to (re)mobilization of Pb from polluted parts of the lake catchment, and indicates the change of catchment soils from a pollution sink to a heavy metal source. The strong reduction of anthropogenic Pb in the uppermost lake sediments since the 1960s has been caused by advances of environmental protection. The lake sediments record the changing fluxes and the isotope composition of the deposited aeolian Pb pollution. During the 20th century aeolian Pb fluxes to the lake sediments were in the range of 1--4 {micro}g/cm{sup 2}/a. During peak emission periods of gasoline Pb to the atmosphere (1960--1990) the aerosol Pb isotope composition was rather constant ({sup 206}Pb/{sup 207}Pb: 1.12--1.13) and probably a mixture of Canadian and Australian with Russian and Central European Pb types. Aeolian Pb isotope and Pb flux trends in the lake sediments as a whole agree well with the trends found in Alpine glaciers (Doering et al., 1997a,b) and in ombrotrophic peat bogs of Switzerland (Shotyk et al., 1996). However, different industrial Pb components were deposited in the archives of aeolian pollution during the early 20th century.

    Oscillations of lake levels in Central Eastern Europe during the Holocene are crucial records of past regional climatic conditions reflecting the balance between evaporation and precipitation in their catchment. Lake Stiucii (38 ha, 10 m depth) is located in Transylvanian Plain (NW Romania) at 296 m asl. A recently extracted sediment core from the central part of the lake provides the first ostracod sediment record of the lake water level fluctuations in this region covering the last 5000 cal years BP. The sediment sequence yielded approximately 1600 valves of 18 freshwater and halophile ostracod species of 11 genera. The most abundant and frequent in the entire record were Heterocypris salina (Brady 1868), Limnocythere inopinata (Baird 1843) and Plesiocypridopsis newtoni (Brady & Robertson 1870) (abundance range between 16-25%). The ostracod assemblages also show a marked variability in diversity and abundance over the past 5000 years, which appear to closely follow water level oscillations. The assemblages indicate three periods of low diversity and density of ostracods primarily represented by Candonidae between (i) 3800 and 3150 cal yr BP, (ii) 2900 and 2400 cal yr BP and (iii) 1600 and 1200 cal yr BP and probably reflect a response to low lake water levels. This inference is supported by the deposition of gyttja and low Zr concentrations. The dominance of Cyclocypris ovum (Jurine, 1820) and Candoninae in a ostracod community of otherwise poor density and diversity between 2200 and 1800 cal yr BP probably reflects littoral environments in the central, deepest part of the present lake. The ostracod assemblages diversified (up to 10 species) between 1100 and 250 cal yr BP and are dominated by co-occurrences of halophile species e.g. Heterocypris salina and Plesiocypridopsis newtoni until 700 cal yr BP, suggesting increased supply of salty water into the lake by salt springs. Thereafter Limnocythere inopinata, a typical shallow water species (<10 m) is dominant

    In Part I, neuroscience collaborators with the Nazis were discussed, and in Part II, neuroscience resistors were discussed. In Part III, we discuss the tragedy regarding european neuroscientists who became victims of the Nazi onslaught on “non-Aryan” doctors. Some of these unfortunate neuroscientists survived Nazi concentration camps, but most were murdered. We discuss the circumstances and environment which stripped these neuroscientists of their profession, then of their personal rights and freedom, and then of their lives. We include a background analysis of anti-Semitism and Nazism in their various countries, then discuss in depth seven exemplary neuroscientist Holocaust victims; including Germans Ludwig Pick, Arthur Simons, and Raphael Weichbrodt, Austrians Alexander Spitzer and Viktor Frankl, and Poles Lucja Frey and Wladyslaw Sterling. by recognizing and remembering these victims of neuroscience, we pay homage and do not allow humanity to forget, lest this dark period in history ever repeat itself.

A survey revealed the presence of tick-borne bacteria Anaplasma phagocytophilum (6.25%) and parasitic protozoa Toxoplasma gondii (3.1%). These data indicate an infectious status of the great cormorant population nesting in Slovakia; they might suggest a degree of environmental contamination by infectious agents and demonstrate the role of migratory seabirds in the circulation and dispersal of pathogens with zoonotic potential.

    It is shown which information can be extracted from the monitoring of radionuclides emitted from the Fukushima Dai-ichi nuclear power plant and transported to Europe. In this part the focus will be on the analysis of the concentration ratios. While (131)I, (134)Cs and (137)Cs were reported by most stations, other detected radionuclides, reported by some, are (95)Nb, (129m)Te, (132)Te, (132)I, (136)Cs and (140)La. From their activity ratios a mean burn-up of 26.7 GWd/t of the fuel from which they originated is estimated. Based on these data, inventories of radionuclides present at the time of the accident are calculated. The caesium activity ratios indicate emissions from the core of unit 4 which had been unloaded into the fuel storage pool prior to the accident.

    Nitrogen input from agricultural ammonia emissions into the environment causes numerous environmental and health problems. The purpose of this study is to present and evaluate an improved ammonia emission inventory based on a dynamical temporal parameterization suitable to compare and assess ammonia abatement strategies. The setup of the dynamical time profile (DTP) consists of individual temporal profiles for ammonia emissions, calculated for each model grid cell, depending on temperature, crop type, fertilizer and manure application, as well as on local legislation. It is based on the method of Skjøth et al., 2004 and Gyldenkærne et al., 2005. The method has been modified to cover the study area and to improve the performance of the emission model. To compare the results of the dynamical approach with the results of the static time profile (STP) the ammonia emission parameterizations have been implemented in the SMOKE for Europe emission model. Furthermore, the influence on secondary aerosol formation in the North Sea region and possible changes triggered through the use of a modified temporal distribution of ammonia emissions were analysed with the CMAQ chemistry transport model. The results were evaluated with observations of the European Monitoring and Evaluation Programme (EMEP). The correlation coefficient of NH3 improved significantly for 12 out of 16 EMEP measurement stations and an improvement in predicting the Normalized Mean Error can be seen for particulate NH4+ and NO3-. The prediction of the 95th percentile of the daily average concentrations has improved for NH3, NH4+ and NO3-. The NH3 concentration modelled with the STP is 157% higher in winter, and about 22% lower in early summer than the one modelled with the new DTP. Consequently, the influence of the DTP on the formation of secondary aerosols is particularly noticeable in winter, when the PM2.5 concentration is 25% lower in comparison to the use of STP for temporal disaggregation.

    West Nile virus (WNV) is a mosquito-transmitted Flavivirus belonging to the Japanese encephalitis antigenic complex of the Flaviviridae family. Its spread in the Mediterranean basin and the Balkans poses a significant risk to human health and forces public health officials to constantly monitor the virus transmission to ensure prompt application of preventive measures. In this context, predictive tools indicating the areas and periods at major risk of WNV transmission are of paramount importance. Spatial analysis approaches, which use environmental and climatic variables to find suitable habitats for WNV spread, can enhance predictive techniques. Using the Mahalanobis Distance statistic, areas ecologically most suitable for sustaining WNV transmission were identified in the Mediterranean basin and Central Europe. About 270 human and equine clinical cases notified in Italy, Greece, Portugal, Morocco, and Tunisia, between 2008 and 2012, have been considered. The environmental variables included in the model were altitude, slope, night time Land Surface Temperature, Normalized Difference Vegetation Index, Enhanced Vegetation Index, and daily temperature range. Seasonality of mosquito population has been modelled and included in the analyses to produce monthly maps of suitable areas for West Nile Disease. Between May and July, the most suitable areas are located in Tunisia, Libya, Egypt, and North Cyprus. Summer/Autumn months, particularly between August and October, characterize the suitability in Italy, France, Spain, the Balkan countries, Morocco, North Tunisia, the Mediterranean coast of Africa, and the Middle East. The persistence of suitable conditions in December is confined to the coastal areas of Morocco, Tunisia, Libya, Egypt, and Israel. PMID:26717483

    Tick-borne encephalitis (TBE), the most serious widespread vector-borne disease of humans in Europe, increased from 2- to 30-fold in many Central and Eastern European countries from 1992 to 1993, coinciding with independence from Soviet rule. Unemployment and low income have been shown in Latvia to be statistically associated with high-risk behaviour involving harvest of wild foods from tick-infested forests, and also with not being vaccinated against TBE. Archival data for 1970--2005 record major changes in the agricultural and industrial sectors, and consequent changes in the abiotic and biotic environment and socio-economic conditions, which could have increased the abundance of infected ticks and the contact of humans with those ticks. For example, abandoned agricultural fields became suitable for rodent transmission hosts; use of pesticides and emissions of atmospheric industrial pollutants plummeted; wildlife hosts for ticks increased; tick populations appear to have responded; unemployment and inequality increased in all countries. These factors, by acting synergistically but differentially between and within each country, can explain the marked spatio-temporal heterogeneities in TBE epidemiology better than can climate change alone, which is too uniform across wide areas. Different degrees of socio-economic upheaval caused by political transition in Estonia, Latvia, Lithuania, Slovenia and the Czech Republic can apparently explain the marked variation in TBE upsurge. Causal linkage between national socio-economic conditions and epidemiology is strongly indicated by striking correlations across eight countries between the degree of upsurge of TBE and both poverty and household expenditure on food (R2 = 0.533 and 0.716, respectively).

    In last decades earthquake swarms in West Bohemia, Central Europe, are monitored by a local seismic network WEBNET consisting of nine stations. In 2003 two GPS permanent observatories MARJ and POUS belonging to European permanent network EPN were established in NW Bohemia to detect possible inter-, co- and post- seismic slips of the earthquake swarms. Individual swarm events are often clustered and grouped sharply round a few tectonic fault zones. On 22 February 2004 a deep swarm of around 50 events in magnitude ML range -0.5 to 1.4 occurred in the Novy Kostel zone. Most of its events fitted in elongated cluster with -30° strike in the depth of 13.5 km differed from the main -11° strike of the Novy Kostel zone. The cluster lay 2 km apart from the main fault plane to west and preliminary focal event mechanisms displayed dip-slip regime. This two azimuth foci bifurcation most likely corresponds to two tectonic systems of this area. After the February 2004 swarm for almost two weeks the total post-seismic slip up to 10 mm was observed between time series of GPS observatories. The detected slip seems to match well to the deep-seated fault system with the -30° strike. It is remarkable that this system fits well just to pronounce gravity gradient zone existing in this area. Mutual relations among the slip movements, local earthquake occurrences and geological data will be displayed and discussed. The research was supported by the Czech Science Foundation (Project 205/05/2287), the Grant Agency of the Academy of Sciences CR (Project IAA300460507), the Support of Targeted Research programme (Project QS300460551) and the Ministry of Education, Youth and Sport (Projects LC506 and 1P05ME781).

    We study the crust-mantle and lithosphere-asthenosphere boundaries (Moho and LAB) in Central Europe, specifically below the Upper Rhine Graben (URG) rift, the Eifel volcanic region and their surrounding areas. Teleseismic recordings at permanent and mobile stations are analysed to search for shear (S) wave to compressional (P) wave converted phases. After a special processing these phases are identified in shear wave receiver functions (S-RFs). Conversions from the Moho at 2.9-3.3 s arrival time are the clearest signals in the S-RFs and indicate a relatively flat Moho at 27-30 km depth. A negative polarity conversion signal at 7-9 s arrival time can be explained with a low shear wave velocity zone (LVsZ) in the upper mantle. We use forward S-RF waveform modelling and Monte-Carlo techniques to determine shear wave velocity (vs)-depth (z) profiles which explain the observed S-RF and which outline variations of the lithospheric thickness in the study region. Across the URG rift and its surrounding mountain ranges (Black Forest, Odenwald etc.) the LAB is at a depth of about 60 ± 5 km. This depth is found for the rift itself as well as for the rift shoulders. Southeast and southwest of the URG, in the regions of the Swabian Alb and Vosges Mountains, the LAB dips to about 78 ± 5 km depth. In the volcanic Eifel region the LAB is at a much shallower depth of just 41 ± 5 km. There an upwelling mantle plume thermally eroded the lower lithosphere. The reduction of vs is about 2%-4% in the upper asthenosphere compared to the lower lithosphere. This vs contrast may be explained with a low portion of partial melt or hydrous minerals in the asthenosphere.

    The 40-year long period of heavy industrialization in Central Europe (1950-1990) was accompanied by burning of arsenic-rich lignite in thermal power plants, and accumulation of anthropogenic arsenic in forest soils. There are fears that retreating acidification may lead to arsenic mobilization into drinking water, caused by competitive ligand exchange. We present monthly arsenic concentrations in surface runoff from 12 headwater catchments in the Czech Republic for a period of 13 years (1996-2008). The studied area was characterized by a north-south gradient of decreasing pollution. Acidification, caused mainly by SOx and NOx emissions from power plants, has been retreating since 1987. Between 1996 and 2003, maximum arsenic concentrations in runoff did not change, and were < 1 ppb in the rural south and < 2 ppb in the industrial north. During the subsequent two years, 2004-2005, maximum arsenic concentrations in runoff increased, reaching 60% of the drinking water limit (10 ppb). Starting in 2006, maximum arsenic concentrations returned to lower values at most sites. We discuss three possible causes of the recent arsenic concentration maximum in runoff. We rule out retreating acidification and a pulse of high industrial emission rates as possible controls. The pH of runoff has not changed since 1996, and is still too low (<6.5) at most sites for an As-OH(-) ligand exchange to become significant. Elevated arsenic concentrations in runoff in 2004-2005 may reflect climate change through changing hydrological conditions at some, but not all sites. Dry conditions may result in elevated production of DOC and sulfur oxidation in the soil. Subsequent wet conditions may be accompanied by acidification leading to faster dissolution of arsenic-bearing sulfides, dissolution of arsenic-bearing Fe-oxyhydroxides, and elevated transport of arsenic sorbed on organic matter. Anaerobic domains exist in normally well-aerated upland soils for hours-to-days following precipitation

    In this work, we present the first study resolving the temporal evolution of δ2H and δ18O values in cloud droplets during 13 different cloud events. The cloud events were probed on a 937 m high mountain chain in Germany in the framework of the Hill Cap Cloud Thuringia 2010 campaign (HCCT-2010) in September and October 2010. The δ values of cloud droplets ranged from −77‰ to −15‰ (δ2H) and from −12.1‰ to −3.9‰ (δ18O) over the whole campaign. The cloud water line of the measured δ values was δ2H=7.8×δ18O+13×10−3, which is of similar slope, but with higher deuterium excess than other Central European Meteoric Water Lines. Decreasing δ values in the course of the campaign agree with seasonal trends observed in rain in central Europe. The deuterium excess was higher in clouds developing after recent precipitation revealing episodes of regional moisture recycling. The variations in δ values during one cloud event could either result from changes in meteorological conditions during condensation or from variations in the δ values of the water vapor feeding the cloud. To test which of both aspects dominated during the investigated cloud events, we modeled the variation in δ values in cloud water using a closed box model. We could show that the variation in δ values of two cloud events was mainly due to changes in local temperature conditions. For the other eleven cloud events, the variation was most likely caused by changes in the isotopic composition of the advected and entrained vapor. Frontal passages during two of the latter cloud events led to the strongest temporal changes in both δ2H (≈ 6‰ per hour) and δ18O (≈ 0.6‰ per hour). Moreover, a detailed trajectory analysis for the two longest cloud events revealed that variations in the entrained vapor were most likely related to rain out or changes in relative humidity and temperature at the moisture source region or both.

  3. Homosexuality and HIV/AIDS prevention: the challenge of transferring lessons learned from Western Europe to Central and Eastern European Countries.

    2005-03-01

    In order to stem the rapidly growing HIV/AIDS epidemics in Eastern Europe a transfer of prevention know-how and experience from Western European countries is necessary. The success of such a transfer is contingent on addressing a number of challenging issues. Monolithic ideas of East/West difference need to give way to the growing empirical evidence which not only shows a tremendous diversity but also many similarities among the 51 countries within the WHO European region. These include similarities regarding sexual attitudes and HIV prevention needs. Western constructs such as a gay identity need to be de-emphasized however, when it comes to promoting human rights (and thus improving HIV prevention for men who have sex with men) in Central and Eastern Europe. In asking the question of what should be transferred from Western Europe to other countries, both the strengths and weaknesses of the last 20 years of prevention need to be considered. In terms of Western European research the strength lies in identifying the social structural causes of HIV transmission. In terms of practice, the successes of instituting country-level structures while also working within the gay community are to be emphasized. Short-comings are evident in terms of reaching men of lower socio-economic status, cultural minorities and sex workers. On such questions, the expertise of Europe as a whole is needed in order to find new answers. PMID:15668214

    The objective of our study was to provide a genotype analysis of H7N7 and H7N9 influenza A viruses (IAV) and infer their relationships to co-circulating non-H7 IAV genomes. The H7N7 strains were collected in central Europe (Hungary-1, Czech Republic-1, Slovenia-1 and Poland-4) and the H7N9 in the Czech Republic and Spain between 2007 and 2011. Hand in hand with this effort, a novel IAV genotype visualization approach called digital genotyping was developed. This approach relies on phylogenetic data summarization and transformation into a pixel array called a segment identity matrix. The digital genotyping revealed a complicated genetic interplay between the H7 and co-circulating non-H7 IAV genotypes. At the H7 IAV level the most obvious relationships were observed between one Polish H7N7/446/09 and Czech H7N7/11 viruses which, despite the special and temporal distance of 800 km and 15 months, retained at least 6/8 genome segments. Close relationships were also observed between the Czech H7N9, Polish and Slovenian H7N7 on one hand and Hungarian and Slovenian H7N7 isolates on the other. In addition the former genomes exhibited close interplays with the Czech H6N2/09 and H11N9/10-like viruses. The Czech and Spanish H7N9 genomes were completely different and 6/8 of the Czech H7N9-like segments were traced to either the Czech H3N8/07, H11N9/09 and Polish H7N7/09-like viruses. The results of digital genotyping correlated with the previous observations obtained on the Polish H7N7 isolates. As was demonstrated, the digital genotyping provides a well-arranged and easily interpretable output and may serve as an alternative genotyping tool useful for handling and analysing even a large panel of IAV genomes.

    Initial objectives and design of the Benchmark campaign organized within the European COST Action ES1206 (2013-2017) are described in the paper. This campaign has aimed to support the development and validation of advanced Global Navigation Satellite System (GNSS) tropospheric products, in particular high-resolution and ultra-fast zenith total delays (ZTDs) and tropospheric gradients derived from a dense permanent network. A complex data set was collected for the 8-week period when several extreme heavy precipitation episodes occurred in central Europe which caused severe river floods in this area. An initial processing of data sets from GNSS products and numerical weather models (NWMs) provided independently estimated reference parameters - zenith tropospheric delays and tropospheric horizontal gradients. Their provision gave an overview about the product similarities and complementarities, and thus a potential for improvements of a synergy in their optimal exploitations in future. Reference GNSS and NWM results were intercompared and visually analysed using animated maps. ZTDs from two reference GNSS solutions compared to global ERA-Interim reanalysis resulted in accuracy at the 10 mm level in terms of the root mean square (rms) with a negligible overall bias, comparisons to Global Forecast System (GFS) forecasts showed accuracy at the 12 mm level with the overall bias of -5 mm and, finally, comparisons to mesoscale ALADIN-CZ forecast resulted in accuracy at the 8 mm level with a negligible total bias. The comparison of horizontal tropospheric gradients from GNSS and NWM data demonstrated a very good agreement among independent solutions with negligible biases and an accuracy of about 0.5 mm. Visual comparisons of maps of zenith wet delays and tropospheric horizontal gradients showed very promising results for future exploitations of advanced GNSS tropospheric products in meteorological applications, such as severe weather event monitoring and weather nowcasting

    In Central and Eastern Europe following the political transformations of the late 1980s and early 1990s there were dramatic declines in marriage and childbearing, significant increases in nonmarital cohabitation and childbearing, and a movement from reliance on abortion to a reliance on contraception for fertility limitation. Although many explanations have been offered for these trends, we offer new explanations based on ideational influences and the intersection of these ideational influences with structural factors. We focus on the political, economic, social, and cultural histories of the region, with particular emphasis on how countries in the region have interacted with and been influenced by Western European and North American countries. Our explanations emphasize the role of developmental models in guiding change in the region, suggesting that developmental idealism influenced family and demographic changes following the political transformations. Developmental idealism provides beliefs that modern family systems help to produce modern political and economic accomplishments and helps to establish the importance of freedom and equality as human rights in both the public and private spheres. The disintegration of the governments and the fall of the iron curtain in the late 1980s and early 1990s brought new understanding about social, economic, and family circumstances in the West, increasing consumption aspirations and expectations which clashed with both old economic realities and the dramatic declines in economic circumstances. In addition, the dissolution of the former governments removed or weakened systems supporting the bearing and rearing of children, and, the legitimacy of the former governments and their programs was largely destroyed, removing government support for old norms and patterns of behavior. In addition, the attacks of previous decades on the religious institutions in the region had in many places left these institutions weak. During this

    Geochemical and mineralogical studies of paleosols provide essential information for paleoclimatic and paleoenvironmental interpretation of continental deposits and can present a high-resolution proxy for paleoclimate. Consequently, paleosols can help to interpret the history of sediment deposition and the autogenic and allogenic processes that influenced a sedimentary basin. Paleosols are also helpful in stratigraphic studies, including sequence stratigraphic analyses. They are used for stratigraphic correlations at the local and basinal scale, and some workers have calculated sediment accumulation rates based on the degree of paleosol development. The horizons of paleosols are widely used as key horizons for the stratigraphic subdivision of continental sedimentary series. The reliability of usage of paleopedologic data has increased, especially with the development of methods of absolute and relative dating: radiocarbon, luminescent, paleomagnetic, amino acid, and paleontological (palynological and paleofaunistic) with geochemical and clay mineralogical data. The use of paleosols as components of the stratigraphic record has increased, especially after paleosols morphotypical features of different ages were studied. Paleosols in various sediment sections were once compound units of soil covers of different ages. Results from geochemical climofunctions applied to Upper Pliocene-Lower Pleistocene red clays and paleosols located in East-Central Europe (Austria, Slovakia, Hungary, Serbia and Romania) together with other geochemical data, clay mineralogy and fossil record, indicate that there were three major periods of their development. 1. The older type red clay/paleosol (age ~4.2-3.2 Ma) is red kaolinitic clay containing typically disordered kaolinite, mixed-layer smectite/kaolinite, smectite and little gibbsite. It was formed in the local subaerial weathering crust in warm, humid, subtropical or monsoon climate. 2. The younger type (age ~3.2-2.5 Ma) contains red

    Hydrological and meteorological extremes (HMEs) in Central Europe during the past 500 years can be reconstructed based on instrumental and documentary data. Documentary data about weather and related phenomena represent the basic source of information for historical climatology and hydrology, dealing with reconstruction of past climate and HMEs, their perception and impacts on human society. The paper presents the basic distribution of documentary data on (i) direct descriptions of HMEs and their proxies on the one hand and on (ii) individual and institutional data sources on the other. Several groups of documentary evidence such as narrative written records (annals, chronicles, memoirs), visual daily weather records, official and personal correspondence, special prints, financial and economic records (with particular attention to taxation data), newspapers, pictorial documentation, chronograms, epigraphic data, early instrumental observations, early scientific papers and communications are demonstrated with respect to extraction of information about HMEs, which concerns usually of their occurrence, severity, seasonality, meteorological causes, perception and human impacts. The paper further presents the analysis of 500-year variability of floods, droughts and windstorms on the base of series, created by combination of documentary and instrumental data. Results, advantages and drawbacks of such approach are documented on the examples from the Czech Lands. The analysis of floods concentrates on the River Vltava (Prague) and the River Elbe (Děčín) which show the highest frequency of floods occurring in the 19th century (mainly of winter synoptic type) and in the second half of the 16th century (summer synoptic type). Reported are also the most disastrous floods (August 1501, March and August 1598, February 1655, June 1675, February 1784, March 1845, February 1862, September 1890, August 2002) and the European context of floods in the severe winter 1783/84.

    Uncertainties posed by climate change and rapidly rising global water demand suggest that existing conflicts over water resources are likely to be exacerbated and new conflicts will appear where little or no conflict occurs today. Successfully planning for and preventing conflicts first requires a sound scientific understanding of the timing, location, and magnitude of water resource shortfalls, identification of the most appropriate climate adaptation options based on multiple criteria, and development of broad, multi-level consensus within the affected community. We recently applied this approach in a World Bank-funded adaptation assessment for the agricultural sectors of four countries in Eastern Europe and Central Asia-Albania, Macedonia, Moldova, and Uzbekistan. For each major basin, we first used a hydrological model to project changes in water availability through 2050 under country-specific high, medium, and low climate impact scenarios. Next, under the three climate scenarios, we projected changes in agricultural water demand using a crop model (i.e., AquaCrop and DSSAT), and changes in water demand in other sectors based on population projections and sectoral forecasts of changes in per capita use. We incorporated these water availability and demand projections-along with other characteristics of the water system such as water supply priorities, environmental and transboundary flow requirements, irrigation efficiency, and reservoir locations and volumes-into a monthly integrated water resource planning tool (the Water Evaluation And Planning tool, or WEAP) to generate projected unmet water demand under each climate scenario and to each sector through 2050. The findings suggest that the agricultural sector in each country (except the relatively water-rich Albania) would experience significant unmet water demands, up to 52 percent in the Syr Darya and Amu Darya River basins of Uzbekistan. Potential adaptation responses to address unmet water demands-such as

    MEEREB is an informal network of rabies experts from the Middle East, Eastern Europe and Central Asia, seeking to eliminate rabies from the region. They met for the second time to review the current rabies situation, both globally and in their respective countries, highlighting current rabies control problems and potential solutions. Success stories in Latin America, in Western Europe, in some Asian countries, as well as in Croatia and Serbia prove that elimination of human rabies is achievable in the MEEREB region. It requires political willingness and cooperation of all stakeholders, including Ministries of Health and of Agriculture; adequate management of animal bites through post-exposure prophylaxis; pre-exposure prophylaxis for populations at high risk of rabies exposure, animal vaccination and humane control of stray dog populations. MEEREB members called for a regional initiative for rabies elimination in Eastern Europe and the Middle East. They are confident that the elimination of human rabies of canine origin can be achieved in the region through adopting a One Health approach, and that campaigns for rabies elimination will have significant benefit for public health, including strengthening the structure for control of other zoonoses.

    We present here a reappraisal of the tectonic setting, stratigraphy and palaeogeography of the central part of the Sivas Basin from Palaeocene to late Miocene. The Sivas Basin is located in the collision zone between the Pontides (southern Eurasia) and Anatolia (a continental block rifted from Gondwana). The basin overlies ophiolites that were obducted onto Anatolia from Tethys to the north. The Central Anatolian Crystalline Complex (CACC) experienced similar ophiolite obduction during Campanian time, followed by exhumation and thrusting onto previously emplaced units during Maastrichtian time. To the east, crustal extension related to exhumation of the CACC created grabens during the early Tertiary, including the Sivas Basin. The Sivas Basin underwent several tectonic events during Paleogene-Neogene. The basin fill varies, with several sub-basins, each being characterised by a distinctive sequence, especially during Oligocene and Miocene. Evaporite deposition in the central part of the basin during early Oligocene was followed by mid-late Oligocene fluvio-lacustrine deposition. The weight of overlying fluvial sediments triggered salt tectonics and salt diapir formation. Lacustrine layers that are interbedded within the fluviatile sediments have locally yielded charophytes of late Oligocene age. Emergent areas including the pre-existing Sivas Basin and neighbouring areas were then flooded from the east by a shallow sea, giving rise to a range of open-marine sub-basins, coralgal reef barriers and subsiding, restricted-marine sub-basins. Utilising new data from foraminifera, molluscs, corals and nannoplankton, the age of the marine transgression is reassessed as Aquitanian. Specifically, age-diagnostic nannoplankton assemblages of classical type occur at the base of the transgressive sequence. However, classical stratigraphic markers have not been found within the planktic foraminiferal assemblages, even in the open-marine settings. In the restricted-marine sediments

    The invasive alien species Ambrosia artemisiifolia (common or short ragweed) is increasing its range in Europe. In the UK and the Netherlands, airborne concentrations of Ambrosia pollen are usually low. However, more than 30 Ambrosia pollen grains per cubic metre of air (above the level capable to trigger allergic symptoms) were recorded in Leicester (UK) and Leiden (NL) on 4 and 5 September 2014. The aims of this study were to determine whether the highly allergenic Ambrosia pollen recorded during the episode could be the result of long distance transport, to identify the potential sources of these pollen grains and to describe the conditions that facilitated this possible long distance transport. Airborne Ambrosia pollen data were collected at 10 sites in Europe. Back trajectory and atmospheric dispersion calculations were performed using HYSPLIT_4. Back trajectories calculated at Leicester and Leiden show that higher altitude air masses (1500 m) originated from source areas on the Pannonian Plain and Ukraine. During the episode, air masses veered to the west and passed over the Rhône Valley. Dispersion calculations showed that the atmospheric conditions were suitable for Ambrosia pollen released from the Pannonian Plain and the Rhône Valley to reach the higher levels and enter the airstream moving to northwest Europe where they were deposited at ground level and recorded by monitoring sites. The study indicates that the Ambrosia pollen grains recorded during the episode in Leicester and Leiden were probably not produced by local sources but transported long distances from potential source regions in east Europe, i.e. the Pannonian Plain and Ukraine, as well as the Rhône Valley in France.

    The aim of the study described in this article was to assess the physicochemical quality of water resources in Isfahan province, located in the central part of Iran, from June to November 2012. Comparison of the results with the acceptable limits recommended by the World Health Organization (WHO) for drinking water showed that nitrate, chloride, iron, and fluoride concentrations exceeded the maximum acceptable level in 12.3%, 9.2%, 6.8%, and 1.5% of samples, respectively. Total dissolved solids (TDS) and turbidity values also exceeded the maximum acceptable level in 9.2% and 3.1% of samples, respectively. In general, the quality of drinking water resources in the central part of Iran at present is mostly acceptable and satisfactory. It may be deteriorated in the future, however, because water quantity and quality in arid and semiarid areas are highly variable over time. Therefore, continued monitoring of the water resources quality is extremely important to environmental safety.

    The Poison Creek Anticline is a major fold that occupies a large part of the western part of the Lemhi Range. The fold is now broken by normal faults, but removal of displacement on the normal faults permitted reconstruction of the anticline. The fold formed during late Mesozoic compressional deformation in the hinterland of the Cordilleran thrust belt. It is in the hanging wall of the Poison Creek thrust fault, a major fault in east-central Idaho, that displaced Proterozoic strata over lower Paleozoic rocks.

    Rodents comprise more species than any other mammal order. Most rodents are considered keystone species in their ecological communities, hence the survival of many other species in the ecosystem depend on them. From medical point of view, this is particularly important for rodent-dependent pathogens. In the particular case of tick-borne diseases, rodents are important as hosts for vector ticks and as reservoir hosts (Lyme borreliosis, human granulocytic anaplasmosis, Crimean-Congo hemorrhagic fever, Tick-borne relapsing fevers, tick-borne rickettsioses, babesiosis). Community and population ecology of rodents was shown to be correlated with disease ecology in the case of many tick-borne diseases. In Eastern Europe, several adult hard-tick species use rodents as their principal hosts: Ixodes apronophorus, I. crenulatus, I. laguri, I. redikorzevi, I. trianguliceps. However, the majority of ticks feeding on rodents are immature stages of ticks which as adults are parasitic on larger mammals. Larvae and nymphs of Ixodes ricinus, the most abundant and medically important tick from Europe, are commonly found on rodents. This is particularly important, as many rodents are synanthropic and, together with other micromammals and birds are often the only available natural hosts for ticks in urban environments. This work reviews the correlated ecology of rodents and I. ricinus.

    Analysis of the hydrographic data collected during seven consecutive high resolution summer/winter cruises in the central part of the South Brazil Bight off the coastal city of Ubatuba confirmed an observable summer/winter stratification variability of the shelf waters. The maximum bulk stratification occurred at mean distances of 85.6 km and 39.1 km from the coast in the austral winter and summer cruises, respectively. Estimates of the equivalent mixing power of the physical processes that increase or decrease the stratification in the inner and middle shelves showed that both shelf regions would be vertically well mixed were it not for buoyancy advection. In the inner shelf, buoyancy advection was associated with the along-shelf transport of low salinity waters originating from river runoff. In the middle shelf, buoyancy advection was due to the oceanic South Atlantic Central Water intrusions toward the coast.

    Abstract Generally, women are less likely than men to disclose their HIV status. This analysis examined the relationship between HIV disclosure and (1) perceived barriers to care and (2) quality of life (QoL) for women with HIV. The ELLA (EpidemioLogical study to investigate the popuLation and disease characteristics, barriers to care, and quAlity of life for women living with HIV) study enrolled HIV-positive women aged ≥18 years. Women completed the 12-item Barriers to Care Scale (BACS) questionnaire. QoL was assessed using the Health Status Assessment. BACS and QoL were stratified by dichotomized HIV disclosure status (to anyone outside the healthcare system). Multilevel logistic regression analysis was used to identify factors associated with disclosure. Of 1945 patients enrolled from Latin America, China, Central/Eastern Europe, and Western Europe/Canada between July 2012 and September 2013, 1929 were included in the analysis (disclosed, n = 1724; nondisclosed, n = 205). Overall, 55% of patients lived with a husband/partner, 53% were employed, and 88% were receiving antiretroviral therapy. Patients who were with a serodiscordant partner were more likely to disclose (p = 0.0003). China had a disproportionately higher percentage of participants who did not disclose at all (nearly 30% vs. <15% for other regions). Mean BACS severity scores for medical/psychological service barriers and most personal resource barriers were significantly lower for the disclosed group compared with the nondisclosed group (p ≤ 0.02 for all). Compared with the disclosed group, the nondisclosed group reported statistically significantly higher (p ≤ 0.03) BACS item severity scores for 8 of the 12 potential barriers to care. The disclosed group reported better QoL. Overall, HIV nondisclosure was associated with more severe barriers to accessing healthcare by women with HIV. PMID:27551959

    Conflict and warfare are central but also disputed themes in discussions about the European Neolithic. Although a few recent population studies provide broad overviews, only a very limited number of currently known key sites provide precise insights into moments of extreme and mass violence and their impact on Neolithic societies. The massacre sites of Talheim, Germany, and Asparn/Schletz, Austria, have long been the focal points around which hypotheses concerning a final lethal crisis of the first Central European farmers of the Early Neolithic Linearbandkeramik Culture (LBK) have concentrated. With the recently examined LBK mass grave site of Schöneck-Kilianstädten, Germany, we present new conclusive and indisputable evidence for another massacre, adding new data to the discussion of LBK violence patterns. At least 26 individuals were violently killed by blunt force and arrow injuries before being deposited in a commingled mass grave. Although the absence and possible abduction of younger females has been suggested for other sites previously, a new violence-related pattern was identified here: the intentional and systematic breaking of lower limbs. The abundance of the identified perimortem fractures clearly indicates torture and/or mutilation of the victims. The new evidence presented here for unequivocal lethal violence on a large scale is put into perspective for the Early Neolithic of Central Europe and, in conjunction with previous results, indicates that massacres of entire communities were not isolated occurrences but rather were frequent features of the last phases of the LBK.

    The post-Communist transition to social health insurance in many of the Central and Eastern European and Central Asian countries provides a unique opportunity to try to answer some of the unresolved issues in the debate over the relative merits of social health insurance and tax-financed health systems. This paper employs regression-based generalizations of the difference-in-differences method on panel data from 28 countries for the period 1990-2004. We find that, controlling for any concurrent provider payment reforms, adoption of social health insurance increased national health spending and hospital activity rates, but did not lead to better health outcomes.

    The post-Communist transition to social health insurance in many of the Central and Eastern European and Central Asian countries provides a unique opportunity to try to answer some of the unresolved issues in the debate over the relative merits of social health insurance and tax-financed health systems. This paper employs regression-based generalizations of the difference-in-differences method on panel data from 28 countries for the period 1990-2004. We find that, controlling for any concurrent provider payment reforms, adoption of social health insurance increased national health spending and hospital activity rates, but did not lead to better health outcomes.

    Abstract A new species of Docosia Winnertz, Docosia dentata sp. n., is described and illustrated, based on a single male specimen collected in Muránska planina National Park in Central Slovakia. DNA sequences (COI, COII, CytB, and ITS2) are included and compared for 13 species of Docosia. There was found only little congruence between the molecular results and previous scarce data about interspecific relationships based on morphology. The COI and CytB gene markers showed the highest interspecific gene distances while ITS2 showed the lowest ones. An updated key to the 23 Central European species of Docosia is also presented.

    Since the late 70s, the Early Pleistocene (Gelasian) site of Coste San Giacomo (Anagni Basin, central Italy) has been known amongst palaeontologists for its diverse vertebrate fauna. During the last 5 years, new excavations and the drilling of a 46-m-deep core have provided novel pieces of information. Palaeomagnetic data, pollen and small vertebrates analyses are presented here for the first time and combined with the updated list of the large vertebrates and ostracod analysis in a multidisciplinary perspective. Large and small mammals, pollen and ostracod analyses have allowed an integrated palaeoenvironmental reconstruction of the sedimentary sequence, depicting the evolution of the alluvial plain in the surrounding landscape. Moreover, magnetostratigraphy, pollen and small mammal biochronological data have confirmed the position of the Coste San Giacomo Faunal Unit, focusing the possible age of the mammal assemblage around 2.1 Ma, in a reversed phase before the base of the Olduvai chron. In particular, the occurrence of the large vole Mimomys pliocaenicus has important biochronological significance. The Coste San Giacomo site offers a unique opportunity to investigate the faunal and environmental changes that occurred in Mediterranean Europe during the Early Pleistocene, coinciding with major climatic changes at a global scale. The occurrence of taxa such as Hippopotamus sp. in the assemblage provides evidence of early dispersal events of African taxa prior to the early Homo diffusion into Europe.

    The present study examined the prevalence and acceptance of body piercings and tattoos among a community sample from the southern German-speaking area of Central Europe. A total of 440 respondents completed information about their own body piercings and tattoos and reported whether they would be likely never to have piercings and tattoos in the future. Analyses indicated that 19.8 and 15.2% of respondents had piercings (excluding the earlobe) and tattoos, respectively. Women were more likely to have body piercings than men, but there were no sex differences in tattooing. There were also few sociodemographic differences in piercings and tattoos, and most participants reported being likely to consider body art in the future. These results are considered in relation to prevalence estimates of body art in other Western countries and the associated health risks.

    The aim of the study described in this article was to assess the physicochemical quality of water resources in Isfahan province, located in the central part of Iran, from June to November 2012. Comparison of the results with the acceptable limits recommended by the World Health Organization (WHO) for drinking water showed that nitrate, chloride, iron, and fluoride concentrations exceeded the maximum acceptable level in 12.3%, 9.2%, 6.8%, and 1.5% of samples, respectively. Total dissolved solids (TDS) and turbidity values also exceeded the maximum acceptable level in 9.2% and 3.1% of samples, respectively. In general, the quality of drinking water resources in the central part of Iran at present is mostly acceptable and satisfactory. It may be deteriorated in the future, however, because water quantity and quality in arid and semiarid areas are highly variable over time. Therefore, continued monitoring of the water resources quality is extremely important to environmental safety. PMID:26867290

    Ferula communis is a showy herbaceous plant typical of the Mediterranean area where it is used as a traditional medicine. The plant is a source of bioactive compounds such as daucane sesquiterpenes and prenylated coumarins. In Italy, most of phytochemical studies focused on Sardinian populations where poisonous and nonpoisonous chemotypes were found, while investigations on peninsular populations are scarce. In this work, we report the chemical characterisation of the essential oils obtained from different parts of F. communis growing in central Italy. The chemical profiles of the plant parts, as detected by GC-FID and GC-MS, were different from each other and from those reported in insular populations. Notably, α-pinene (10.5%), γ-terpinene (7.6%) and hedycariol (8.4%) were the major volatile constituents in flowers; α-pinene (55.9%), β-pinene (16.8%) and myrcene (5.9%) in fruits; β-eudesmol (12.1%), α-eudesmol (12.1%) and hedycariol (10.3%) in leaves; (E)-β-farnesene (9.5%), β-cubebene (8.2%) and (E)-caryophyllene (7.2%) in roots. The volatile profiles detected did not allow to classify the investigated central Italy population into the poisonous and nonpoisonous chemotypes previously described in Sardinia.

  16. Molecular phylogeny and population structure of the codling moth (Cydia pomonella) in Central Europe: II. AFLP analysis reflects human-aided local adaptation of a global pest species.

    Originally resident in southeastern Europe, the codling moth (Cydia pomonella L.) (Tortricidae) has achieved a nearly global distribution, being one of the most successful pest insect species known today. As shown in our accompanying study, mitochondrial genetic markers suggest a Pleistocenic splitting of Cydia pomonella into two refugial clades which came into secondary contact after de-glaciation. The actual distribution pattern shows, however, that Central European codling moths have experienced a geographic splitting into many strains and locally adapted populations, which is not reflected by their mitochondrial haplotype distribution. We therefore have applied, in addition to mitochondrial markers, an approach with a higher resolution potential at the population level, based on the analysis of amplification fragment length polymorphisms (AFLPs). As shown in the present study, AFLP markers elucidate the genetic structure of codling moth strains and populations from different Central European apple orchard sites. While individual genetic diversity within codling moth strains and populations was small, a high degree of genetic differentiation was observed between the analyzed strains and populations, even at a small geographic scale. One of the main factors contributing to local differentiation may be limited gene flow among adjacent codling moth populations. In addition, microclimatic, ecological, and geographic constraints also may favour the splitting of Cydia pomonella into many local populations. Lastly, codling moths in Central European fruit orchards may experience considerable selective pressure due to pest control activities. As a consequence of all these selective forces, today in Central Europe we see a patchy distribution of many locally adapted codling moth populations, each of them having its own genetic fingerprint. Because of the complete absence of any correlation between insecticide resistance and geographic or genetic distances among

    The Dinarides are a 200-300-km-wide southwest vergent fold and thrust belt extending along the eastern margin of the Adriatic Sea. The complex and varied structural and stratigraphic relationships can be used to define three major tectonic units: the internal, central, and external Dinarides. In the Internal Dinarides, platform sequences deposited in the Early and Middle Triassic underwent rapid subsidence and drowning in the Late Triassic and Early Jurassic along with rifting and subsequent formation of oceanic crust. Melange and flysch were deposited during the late Jurassic through Cretaceous as the developing thrust belt encroached upon the northeastern margin of the Dinaride carbonate platform. The Dinaride carbonate platform forms the cores of the central and external Dinarides and is composed primarily of Permian-Triassic clastics and evaporites overlain by Middle Triassic through early Eocene platform carbonates. The entire sequence is overlain by late Eocene and early Oligocene synorogenic flysch. In the central Dinarides, late Jurassic and Early Cretaceous unconformities suggest structural uplift prior to the onset of thrusting. Deformation involves Paleozoic basement and includes a major decollement in the Permian Triassic clastic and evaporite unit. Thrusting in the external Dinarides occurred in the late Eocene-early Oligocene and is restricted to Middle Triassic and younger units with major detachments forming near the base of the Ladinian and within a Late Jurassic-Early Cretaceous evaporite. Important oil source and seal lithofacies occur within intraplatform basins and lagoons in the Mesozoic sequences of the central and external Dinarides. Widespread dolomitized units within the Mesozoic carbonate sequence are potential reservoir zones. The presence of surface hydrocarbon seeps and of existing production on trend to the Dinarides in the thrust belt of Italy and Albania suggest the potential for hydrocarbon discoveries in this underexplored area.

  18. Thermochronological record of long term faulting, burial and exhumation history in the Sudetes (Bohemian Massif, Central Europe): a multi-system thermochronological approach

    Reconstructing erosional and faulting history in the old crystalline basement terrains, with lacking or sparse post-tectonic geological records, is a challenging task where even radiometric data on the basement rocks need not to provide ultimate answers. NE part of the Bohemian Massif (known as the Sudetes) represents a classic example where numerous attempts to constrain denudation, faulting and relief formation on the Variscan basement, often based on incomplete lines of evidence, led to formulation of controversial models. In this study we aim to reconstruct the post-orogenic exhumation history of the Rychlebské hory Mts. in the eastern Sudetes and constrain paleo-activity along the Sudetic Marginal Fault (SMF) - one of the morphologically most prominent, but poorly understood features of Central Europe, forming a >140 km long escarpment separating the Sudetic Mountains from the foreland in the northeast. We do so by applying zircon (U-Th)/He (ZHe), apatite fission track (AFT) and apatite (U-Th)/He (AHe) dating methods to the basement samples from different fault-bounded blocks and sparsely preserved post-orogenic sedimentary samples. New thermochronological data reveals that in the Late Cretaceous at ~95-80 Ma, the Carboniferous-Permian basement blocks SW and NE of the SMF were buried to ~4-7 km and >6.5 km depths, respectively, by sediments of the Bohemian Cretaceous Basin System. This finding contradicts the traditional paleogeographic reconstructions suggesting exposure of large portions of the Sudetes for most of the Mesozoic-Cenozoic. During the burial, the SMF acted as a normal fault as documented by offset in ZHe ages across the fault. At 85-70 Ma, the basin was inverted, Cretaceous strata eroded and basement blocks were exhumed to the near-surface at exhumation rate of ~300 m/Ma as evidenced by Late Cretaceous-Paleocene AFT ages and thermal modelling results. There is no appreciable difference in AFT and AHe ages across the fault suggesting that the

    Necrotising fasciitis (NF) is characterised by rapidly spreading necrosis of the soft tissue and fascia. It is rare but can be fatal when not managed properly. The aim of this study is to evaluate the diagnosis, treatment and results such as mortality, morbidity and reconstructive options of NF localised in the central part of the body. The main goal is to emphasise upon the clinical symptoms for early diagnosis which is the most important factor in saving the lives of these patients. Between January 2000 and December 2010, 30 patients with NF localised in central parts of the body were treated. Six of the patients were female (20%) and the others were male (80%). The mean age was 54·03 years (ranged between 26 and 83 years). The average time from the onset of symptoms to diagnosis was 6 days, ranging from 2 to 11 days. The localisation of NF was perineum in 24 patients (80%); inguinal and thigh region in 5 patients (16·7); and back in 1 patient (3·3%). The hospitalisation time was varying between 17 and 32 days (mean 23 days). Six patients (20%) died and 24 patients (80%) survived. All non-survivors had risk factors and secondary comorbidities such as immunosuppression, chronic cardiac failure, and diabetes with high glucose level. Survivors also underwent repeated debridement operation 2-4 times. Reconstructive procedures were split-thickness skin graft (STSG) in eight patients (33·3%), fasciocutaneous flaps in four patients (16·6%), fasciocutaneous flap + STSG in six patients (25%), scrotal flap + STSG in two patients (6·6%), scrotal flap in two patients (6·6%) and musculocutaneous flap + STSG in one patient (3·3%). There was no major complication such as flap and graft loss, after reconstructive procedures. Early diagnosis of NF may be the lifesaving factor. Amuputation can save the patient's life in the case of NF in the extremities; however, this is not an option for NF in central parts of the body. In these cases, when NF is suspected, early

    Hungary, in the centre of Carpathian basin grapples with numerous challenges in order to improve catastrophic indices of environmental conditions of the country, as well as the state of health of the population. Some of these problems are subjects of financial and health policy, and can be solved internally. The remaining environmental problems can only be remedied by cooperation with neighbouring younger countries. This vitally important cooperation is hampered by severe historical conflicts burdening even the present political affiliations. The authors give a short introduction and explanation of the recent sensitive situation in this central European region, as a late consequence of an historical cataclysm happened more than nine decades ago.

    The post-glacial fate of central European grasslands has stimulated palaeoecological debates for a century. Some argued for the continuous survival of open land, while others claimed that closed forest had developed during the Middle Holocene. The reasons behind stability or changes in the proportion of open land are also unclear. We aim to reconstruct regional vegetation openness and test the effects of climate and human impact on vegetation change throughout the Holocene. We present a newly dated pollen record from north-western fringes of the Pannonian Plain, east-central Europe, and reconstruct Holocene regional vegetation development by the REVEALS model for 27 pollen-equivalent taxa. Estimated vegetation is correlated in the same area with a human activity model based on all available archaeological information and a macrophysical climate model. The palaeovegetation record indicates the continuous presence of open land throughout the Holocene. Grasslands and open woodlands were probably maintained by local arid climatic conditions during the early Holocene delaying the spread of deciduous (oak) forests. Significantly detectable human-made landscape transformation started only after 2000 BC. Our analyses suggest that Neolithic people spread into a landscape that was already open. Humans probably contributed to the spread of oak, and influenced the dynamics of hazel and hornbeam.

    The north-central Appalachians occupy a critical position within the 3000+ km-long Appalachian orogen, lying southwest of the boundary between the central and northern Appalachians (CNAB). The one-billion-year-long history of tectonic activity in eastern Laurentia includes the creation and evolution of the Appalachian orogen during the Paleozoic and the Mesozoic transformation of the orogen into a passive margin during Pangea's disassembly. A most important ingredient in the evolution of the orogen was the Alleghany orogeny, which was driven by the convergence and collision between Laurentia (Laurussia) and West Gondwana (Africa). The Alleghany orogeny in the central and southern Appalachians was a de??collement tectonism that involved a larger part of eastern Laurentia than had the previous three orogenies. The fundamental element was a very low-angle thrust (de??collement) that originated in mid-crustal levels east of the presently-exposed Appalachians and rose westwardly to progressively higher levels in the upper crust and the supra-crustal Paleozoic section. Alleghany deformation was widely developed in the hanging-wall block (allochthon), primarily in the form of thrust faults and fold-and-thrust structures, both of which splayed upward from the basal de??collement. The youngest manifestations of the Alleghany orogeny were northeast-trending strike-slip faults and dextral shear zones in the Piedmont. In the north-central Appalachians, the exposed allochthon consists of two parts: the sedimentary externides (Appalachian Plateau and Valley and Ridge provinces) and the crystalline externides (Reading Prong, Blue Ridge belt, and Piedmont province). Long, thrust-cored anticlines predominate in the sedimentary externides. A widespread layer-parallel shortening preceded the folding; it is largely coaxial with the folding but extends considerably farther to the northwest toward the craton. It is hypothesized that the folding developed in reverse order, sequentially

    Oxygen isotope stage 3 (OIS 3) was a mild interval between the two cold maxima of the last (Weichselian) glaciation marked by climate changes oscillating on a 100-1000 yr time scale between near-interglacial and peak-glacial conditions. During OIS 3, modern humans entered Europe, and somewhat later their Neanderthal predecessors became extinct. Our understanding of this momentous event depends on an answer to the question, Did the unstable environmental conditions of the time play a significant role in early human history? The Stage 3 Project is an interdisciplinary study with two main goals: (1) to describe with existing data and to simulate the climates and landscapes of typical warm and cold phases between 45,000 and 30,000 yr ago and (2) to compare the results with the spatial and temporal distribution of human beings in this context. This paper introduces the Stage 3 Project and provides background to a set of papers on the climate and landscape aspects of the Project that will appear in Quaternary Research and to studies of their relevance to the Early Upper Paleolithic of Europe to appear in journals yet to be determined.

    The Chiapanecan Volcanic Arc (CVA) is a 150 km stretch of volcanoes irregularly aligned in a northwest direction, including El Chichón volcano located in the central portion of the State of Chiapas, southern Mexico. It lies between two great volcanic features: the Trans-Mexican Volcanic Arc to the northwest, and the Central American Volcanic Arc to the southeast, in a complex zone of the interaction of the North American, Caribbean and Cocos Plates. The central part of the CVA is composed of an irregular northwest alignment of at least 12 volcanic structures located 80 km to the southeast of El Chichón (the only currently active volcano in the CVA). These structures include one explosion crater (Navenchauc), one collapse structure (Apas), one dome complex (Tzontehuitz) and nine volcanic domes (Navenchauc, Huitepec, Amahuitz, La Iglesia, Mispía, La Lanza, Venustiano Carranza, Miguel Hidalgo and Santotón) with associated pyroclastic flow deposits. The juvenile lithics from these deposits have a porphyritic texture with phenocrysts of plagioclase (±), amphibole (±), clinopyroxene (±), orthopyroxene (±) and Fe-Ti oxides surrounded by a matrix composed by microlites of plagioclase and glass. The chemical results obtained from representative samples from the deposits and structures indicate that these belong to the series of subalkaline rocks, and fall into the calcalkaline field with medium to high contents of potassium. They vary in their composition from andesite to dacite with an interval of silica between a 56 to a 66% (wt.). The ages reported in the literature and obtained in this study by means of the K-Ar and the 40Ar/39Ar methods, respectively, indicated that volcanism was episodic and spanned a time from 2100 ky ago (Tzontehuitz) to 225 ky ago (Venustiano Carranza).

    Graphite furnace atomic absorption spectrometry, with Zeeman background correction and after improved matrix modification, was used to measure the plasma selenium content of healthy blood bank donors in the central part of Belgium. The mean plasma selenium concentration of 80 men and 80 women was 79.7+/-4.4ng/mL with a range of 55.0-117.4ng/mL. There was no gender difference observed. Plasma selenium level was significantly highest for the adult group, aged 45-64 years, compared to the others, except the young adults (18-24 years). The mean plasma selenium concentration measured corresponded well with literature data for Belgium. The obtained values were found to be in the medium range, compared with recent literature values for the European countries. PMID:17980813

    The Paraná Basin is a large sedimentary basin in central-eastern South America that extends through Brazil, Paraguay, Uruguay and Argentina. Evolved completely over the South American continental crust, this Paleozoic basin is filled with sedimentary and volcanic rocks deposited from the Silurian to the Cretaceous, when a significant basaltic effusion covered almost the entire area of the basin. A series of superposed sedimentary and volcanic rock layers were laid down under the influence of different tectonic settings, probably originated from distant collisional dynamics of continental boards that led to the amalgamation of Gondwanaland. The current boundaries of the basin can be the result of issuing erosional or of tectonic origin, such as the building up of large arches and faults. To evaluate the deep structural architecture of the lithosphere under a sedimentary basin is a great challenge, requiring the integration of different geophysical and geological studies. In this paper, we present the resulting Paraná Basin lithospheric model, obtained from processing and inversion of broadband and long-period magnetotelluric soundings along an E-W profile across the central part of the basin, complemented by a qualitative joint interpretation of gravimetric data, in order to obtain a more precise geoelectric model of the deep structure of the region.

    This paper describes a method of estimating emission fluxes of biogenic volatile organic compounds (BVOCs) based on the approach proposed by Guenther et al. (1995) and the high-resolution Corine land-cover 2000 database (1x1km resolution). The computed emission fluxes for the Czech Republic (selected for analysis as being representative of a heavily cultivated, central European country) are compared with anthropogenic emissions, both for the entire country and for individual administrative regions. In some regions, BVOC emissions are as high as anthropogenic emissions; however, in most regions the BVOC emissions are approximately 50% of the anthropogenic emissions. The yearly course of BVOC emissions (represented by monoterpenes and isoprene) is presented, along with the spatial distribution of annual mean values. Differences in emission distributions during winter (January) and summer (June) are also considered. PMID:19773106

    Abstract In the course of a new database project on Miocene to Recent freshwater gastropods of Europe, a great many of primary and secondary homonyms were revealed. Such nomenclatural issues need clarification in order to avoid misunderstandings and wrong statements about geographical distributions and temporal ranges. The following 16 new names are introduced to replace existing homonyms: Theodoxus militaris jurisicpolsakae nom. n., Viviparus stevanovici nom. n., Melanopsis haueri ripanjensis nom. n., Melanopsis wolfgangfischeri nom. n., Micromelania ramacanensis nom. n., Pseudamnicola welterschultesi nom. n., Muellerpalia haszprunari nom. n., Muellerpalia pseudovalvatoides nom. n., Lithoglyphus gozhiki nom. n., Valvata heidemariae willmanni nom. n., Radix macaleti nom. n., Gyraulus okrugljakensis nom. n., Gyraulus rasseri nom. n., Gyraulus vrapceanus nom. n., Planorbarius halavatsi nom. n., and Segmentina mosbachensis nom. n. Additionally, six cases of homonyms are discussed that are not replaced by new names, because they are considered junior synonyms. PMID:25147468

  12. Characterization of the radon source in North-Central Florida. Final report part 1 -- Final project report; Final report part 2 -- Technical report

    SciTech Connect

    1997-12-01

    This report contains two separate parts: Characterization of the Radon Source in North-Central Florida (final report part 1 -- final project report); and Characterization of the Radon Source in North-Central Florida (technical report). The objectives were to characterize the radon 222 source in a region having a demonstrated elevated indoor radon potential and having geology, lithology, and climate that are different from those in other regions of the U.S. where radon is being studied. Radon availability and transport in this region were described. Approaches for predicting the radon potential of lands in this region were developed.

    We assessed the probability of three major natural hazards—windthrow, drought, and forest fire—for Central and South-Eastern European forests which are major threats for the provision of forest goods and ecosystem services. In addition, we analyzed spatial distribution and implications for a future oriented management of forested landscapes. For estimating the probability of windthrow, we used rooting depth and average wind speed. Probabilities of drought and fire were calculated from climatic and total water balance during growing season. As an approximation to climate change scenarios, we used a simplified approach with a general increase of pET by 20%. Monitoring data from the pan-European forests crown condition program and observed burnt areas and hot spots from the European Forest Fire Information System were used to test the plausibility of probability maps. Regions with high probabilities of natural hazard are identified and management strategies to minimize probability of natural hazards are discussed. We suggest future research should focus on (i) estimating probabilities using process based models (including sensitivity analysis), (ii) defining probability in terms of economic loss, (iii) including biotic hazards, (iv) using more detailed data sets on natural hazards, forest inventories and climate change scenarios, and (v) developing a framework of adaptive risk management.

    The demand for agricultural products continues to grow rapidly, but further agricultural expansion entails substantial environmental costs, making recultivating currently unused farmland an interesting alternative. The collapse of the Soviet Union in 1991 led to widespread abandonment of agricultural lands, but the extent and spatial patterns of abandonment are unclear. We quantified the extent of abandoned farmland, both croplands and pastures, across the region using MODIS NDVI satellite image time series from 2004 to 2006 and support vector machine classifications. Abandoned farmland was widespread, totaling 52.5 Mha, particularly in temperate European Russia (32 Mha), northern and western Ukraine, and Belarus. Differences in abandonment rates among countries were striking, suggesting that institutional and socio-economic factors were more important in determining the amount of abandonment than biophysical conditions. Indeed, much abandoned farmland occurred in areas without major constraints for agriculture. Our map provides a basis for assessing the potential of Central and Eastern Europe’s abandoned agricultural lands to contribute to food or bioenergy production, or carbon storage, as well as the environmental trade-offs and social constraints of recultivation.

    Introduction Chronic obstructive pulmonary disease (COPD) constitutes a major health challenge in Central and Eastern European (CEE) countries. However, clinical phenotypes, symptom load, and treatment habits of patients with COPD in CEE countries remain largely unknown. This paper provides a rationale for phenotyping COPD and describes the methodology of a large study in CEE. Methods/design The POPE study is an international, multicenter, observational cross-sectional survey of patients with COPD in CEE. Participation in the study is offered to all consecutive outpatients with stable COPD in 84 centers across the CEE region if they fulfill the following criteria: age >40 years, smoking history ≥10 pack-years, a confirmed diagnosis of COPD with postbronchodilator FEV1/FVC <0.7, and absence of COPD exacerbation ≥4 weeks. Medical history, risk factors for COPD, comorbidities, lung function parameters, symptoms, and pharmaceutical and nonpharmaceutical treatment are recorded. The POPE project is registered in ClinicalTrials.gov with the identifier NCT02119494. Outcomes The primary aim of the POPE study was to phenotype patients with COPD in a real-life setting within CEE countries using predefined classifications. Secondary aims of the study included analysis of differences in symptoms, and diagnostic and therapeutic behavior in participating CEE countries. Conclusion There is increasing acceptance toward a phenotype-driven therapeutic approach in COPD. The POPE study may contribute to reveal important information regarding phenotypes and therapy in real-life CEE. PMID:27042048

  9. The unconventional hydrocarbon potential in the central part of the Baltic Basin

    2014-05-01

    The Baltic Basin is an intracratonic Phanerozoic sedimentary basin, situated on the Western margin of the East European Craton. The unconventional hydrocarbon potential is mostly related to the several organic-rich source rock complexes within the Early Palaeozoic section. In the south-eastern part of the Baltic Basin the Cambrian shales (Alum shales and Middle Cambrian), Ordovician black shales of the Caradocian age and Silurian Llandovery shales are considered as the major potential shale oil/gas playes. The depth of the the base of the Silurian shales varies from 2120 to 1125 m in the Lithuanian part of the basin. The thickness of the Lower Silurian shales in - varies from 110m to160 m. The organic matter of the source rocks is of similar composition - predominantly "oil-producing" sapropel (type II) and mixed "oil-gas liquids producing" type II-III. Pyrolisis yields (32 - 76(~100) kg HC/ton rock) suggests a good hydroacarbon generation potential. Total organic carbon content varies from 0.2-3 to 8-11%. Maximal values of the total organic carbon (up to 17%) have been recorded near the base of the Silurian (2-11 m Middle Llandovery interval) and its content generally decreases upwards the section. The Rock-Eval screening pyrolysis, biomarker data, reflectance of vitrinite-like macerals and conodont colour alteration index show considerable variations of the source rocks maturity through the basin. Maturity of the organic matter increases southwestwards from 0.6 up to 1.94% (Ro). Thermal maturity in this area ranges from immature in the Eastern part of Lithuania and to "oil window" in the Western Lithuania. In some places in central part of the basin (wells Ramučiai-1, Pajūris-1 and others) the anomalously high maturity of organic matter, indicating the lower part of the wet gas/condensate window have been recorded, most probably being related to the locally increased paleo-temperatures. Llandovery shales are clay-rich, an average values range from 28-59vol

    Over the last few decades, ecological factors, combined with everchanging landscapes mainly linked to human activities (e.g. encroachment and tourism) have contributed to modifications in the transmission of parasitic diseases from domestic to wildlife carnivores and vice versa. In the first of this two-part review article, we have provided an account of diseases caused by protozoan parasites characterised by a two-way transmission route between domestic and wild carnivore species. In this second and final part, we focus our attention on parasitic diseases caused by helminth and arthropod parasites shared between domestic and wild canids and felids in Europe. While a complete understanding of the biology, ecology and epidemiology of these parasites is particularly challenging to achieve, especially given the complexity of the environments in which these diseases perpetuate, advancements in current knowledge of transmission routes is crucial to provide policy-makers with clear indications on strategies to reduce the impact of these diseases on changing ecosystems.

    This report pt·esents a description of the stratigraphy, structure, and petrology of the volcanic rocks of the central and northern parts of the Western Cascade Range of Oregon. The study is a part of a long-range cooperative program between the U.S. Geological Survey and the Oregon State Department of Geology and Mineral Industries to prepare a geologic map of Oregon. The map area, about 7,500 square miles, lies in the densely forested western slope of the Cascade Range. It is bounded approximately by lat 43° N. and lat 45°30' N. on the south and north, the crest of the range on the east, and long 123° W. and the edge of the Willamette Valley on the west. The geology, which was mapped by reconnaissance methods, is chiefly based on examination of rock exposures along roads. The Cascade Range in Oregon comprises two physiographic divisions: the Western Cascade Range, which includes a wide, deeply dissected belt of volcanic formations making up the western slope of the range, and the High Cascade Range, which includes chiefly younger cones and lava flows forming the nearly undissected crest of the range. The volcanic rocks of the Western Cascade Range are deformed and partially altered flows and pyroclastic rocks that range in age from late Eocene t·o lute Miocene, as determined chiefly from fossil plants from more than 50 localities. These volcanic rocks overlie or interfinger westward with marine sedimentary rocks, and in the southwestern part of the map area they overlie pre-Tertiary plutonic and metamorphic rocks of the Klamath Mountains.

  12. The spread of modern humans in Europe

    The earliest credible evidence of Homo sapiens in Europe is an archaeological proxy in the form of several artifact assemblages (Bohunician) found in South-Central and possibly Eastern Europe, dating to ≤48,000 calibrated radiocarbon years before present (cal BP). They are similar to assemblages probably made by modern humans in the Levant (Emiran) at an earlier date and apparently represent a population movement into the Balkans during a warm climate interval [Greenland Interstadial 12 (GI 12)]. A second population movement may be represented by a diverse set of artifact assemblages (sometimes termed Proto-Aurignacian) found in the Balkans, parts of Southwest Europe, and probably in Eastern Europe, and dating to several brief interstadials (GI 11–GI 9) that preceded the beginning of cold Heinrich Event 4 (HE4) (≈40,000 cal BP). They are similar to contemporaneous assemblages made by modern humans in the Levant (Ahmarian). The earliest known human skeletal remains in Europe that may be unequivocally assigned to H. sapiens (Peçstera cu Oase, Romania) date to this time period (≈42,000 cal BP) but are not associated with artifacts. After the Campanian Ignimbrite volcanic eruption (40,000 cal BP) and the beginning of HE4, artifact assemblages assigned to the classic Aurignacian, an industry associated with modern human skeletal remains that seems to have developed in Europe, spread throughout the continent.

  13. Use of diagnostic ratios for studying source apportionment and reactivity of ambient polycyclic aromatic hydrocarbons over Central Europe

    Dvorská, Alice; Lammel, Gerhard; Klánová, Jana

    2011-01-01

    Ratios of levels of 9 polycyclic aromatic hydrocarbons (PAHs) in air at central European sites during 1996-2008 were used to assess the suitability of 5 commonly used diagnostic ratios (DRs) for PAH source apportionment. DRs derived from a detailed literature study on emission factors were reflected in ambient air samples only at sites located near major sources. A significant seasonality was observed in a long-term time series of ambient DRs at a background site indicating possible capability of this method to reflect changes in source characteristics. The results of a mass balance study suggest that current knowledge of PAH reactivities is insufficient for a source apportionment based on DRs at receptor sites, even when limited to major types of PAH sources. However, DRs could be used to narrow down ozone and hydroxyl radical reaction rate coefficients' uncertainties: k O 3(2) of pyrene and benzo(ghi)perylene in the particulate phase seem to be ≤ 10% of the highest rate coefficient measured using model aerosols in the laboratory and k O 3(2) of indeno(1,2,3-cd)pyrene in the gas phase could be higher than previously estimated by three orders of magnitude. The suitability of DRs for source apportionment at (especially background) receptor sites cannot be expected in the general case. However, measurements carried out close to sources are in accordance with literature data suggesting that the ratios of benzo(a)anthracene/(benzo(a)anthracene + chrysene) and indeno(123cd)pyrene/(indeno(123cd)pyrene + benzo(ghi)perylene) are capable of distinguishing between traffic and residential heating, while the ratio of anthracene/(anthracene + phenanthrene) was the least useful DR due to its low variability.

  14. From the Western Alps across Central Europe: Postglacial recolonisation of the tufa stream specialist Rhyacophila pubescens (Insecta, Trichoptera)

    PubMed Central

    2011-01-01

    Background Dispersal rates, i.e. the effective number of dispersing individuals per unit time, are the product of dispersal capacity, i.e. a species physiological potential for dispersal, dispersal behaviour, i.e. the decision to leave a habitat patch in favour of another, and connectivity of occupied habitat. Thus, dispersal of species that are highly specialised to a certain habitat is limited by habitat availability. Species inhabiting very stable environments may also adopt a sedentary life-style. Both factors should lead to strong genetic differentiation in highly specialised species inhabiting stable environments. These two factors apply to our model species Rhyacophila pubescens a highly specialised freshwater insect that occurs in tufa springs, a very stable habitat. Results We examined the genetic population structure and phylogeography using range-wide mtCOI sequence and AFLP data from 333 individuals of R. pubescens. We inferred the location of Pleistocene refugia and postglacial colonisation routes of R. pubescens, and examined ongoing local differentiation. Our results indicate intraregional differentiation with a high number of locally endemic haplotypes, that we attributed to habitat specificity and low dispersal rates of R. pubescens. We observed high levels of genetic diversity south of the Alps and genetic impoverishment north of the Alps. Estimates of migrants placed the refugium and the source of the colonisation in the Dauphiné Alps (SW Alps). Conclusions This is the first example of an aquatic insect with a colonisation route along the western margin of the Alps to the Central European highlands. The study also shows that specialisation to a stable environment may have promoted a behavioural shift to decreased dispersal rates, leading to stronger local population differentiation than in less specialised aquatic insects. Alternatively, the occurrence of highly specialised tufa spring habitats may have been more widespread in the past, leading

    The purpose of the study is to quantify the impact of present-day and future urban emission from central European cities on the regional air-quality (AQ), based on a modeling couple of the regional climate model RegCM4.2 and the chemistry transport model CAMx, including two-way interactions. A series of simulations was carried out for the present (2001-2010) decade and two future decades (2026-2035 and 2046-2055) either with all urban emissions included (base case) or without considering urban emissions. As we are interested on the impact of emission changes only, the impact of different driving meteorological conditions in the future (due to climate change) are not considered. The emissions used is the TNO MEGAPOLI European emission database that includes country/sector based scenarios for years 2030 and 2050, which were used for the encompassing decades. Further, the sensitivity of ozone production to urban emissions was examined by performing reduction experiments with -20% emission perturbation of NOx and/or NMVOC. The model was also validated using surface measurements of key pollutants. Selected air-quality measures were used as metrics describing the cities emission impact on regional air pollution. Due to urban emissions, significant ozone titration occurs over cities while over rural areas further from, ozone production is modeled, mainly in terms of number of exceedances and accumulated exceedances over the threshold of 40 ppbv. Urban NOx, SO2 and PM2.5 emissions also significantly contribute to concentrations in the cities themselves (up to 50-70% for NOx and SO2 , and up to 55% for PM2.5), but the contribution is large over rural areas as well (10-20%). Although air pollution over cities is largely determined by the local urban emissions, considerable (often a few tens of %) fraction of the concentration is attributable to other sources from rural areas and minor cities. The future urban emission AQ fingerprint is, in general, slightly smaller than in

    The study area, is located in northwest part of central Anatolian, consists of Eskişehir and Kütahya region where are important for finding occurrence of opaline silica mineralization as well as chalcedonic silica mineralization. In this study preliminary results of mineralogical properties of opals from four different area (Sabuncupınar, Belkavak, Gokçekısık and Derekoy), located between Eskisehir and Kutahya region, have been given. In the Kütahya region, dendritic opal nodules present in Pliocene pyroclastic rocks - Kanoturaǧı hill and white opals outcrop in stockwork veins with serpentinites in Küçükali hill around Sabuncupınar village. The mainly whitish - blue and gray opal nodules range from millimetres in diameter to about five and ten centimetres in Kanoturagı hill. White opals, called milky opal, are white color and present in veins within serpentinites. The Kanoturagı opal is made up of tiny spheres, the milky opal is made up tiny sphere with fibrous texture based on the SEM. Green opals present in Miocene pyroclastic rocks in Belkavak village. The Belkavak opals are greenish color and having a brecciated appearance. Opals outcrops around Sabuncu pınar and Belkavak villages consist of opal - CT, alpha quartz and, moganite, and a lesser amount of opal - C based on the results of XRD analysis. In the Eskişehir region, the dendritic opals occur as nodules in volcanogenetic conglomerates of Pliocene age in the Dereyalak area. The Dereyalak opals vary in size from millimetres in diameter to about ten centimetres. Their color are mainly white, beige, greenish, yellowish orange and black. On the other hand, Pliocene pyroclastic rocks are the host rock of opals in Gökçekısık village - Eskişehir. Gökçekısık Opals are mainly colorless, pale shades of yellow, whitish blue and gray colors and display a reinous to sub vitreous luster. Dereyalak dendiritic opals consist of opal - CT, opal - C and a lesser amount of alpha quartz and, moganite

Based on Bouguer anomaly maps we identified a couple of major trends, one to the northeast of the study area, with a high gravimetric between -90 and -106 mgals, and the other is located southwest of the area, with values of -97 and -113 mgals, these trends are also observed as magnetic domains in aeromagnetic maps. The integration of geophysical and geological models helps to delineate the interface between rocks and underlying sedimentary basement, provide an estimate of their depth, and better define the structural lineament. The recorded activity may be an indicator of regional reactivation. In addition, the central part of the SMOr could be one of the most active intraplate areas in Mexico.

    Underground nests of Talpa europaea, known as the common mole, are very specific microhabitats, which are also quite often inhabited by various groups of arthropods. Mites from the suborder Uropodina (Acari: Mesostigmata) are only one of them. One could expect that mole nests that are closely located are inhabited by communities of arthropods with similar species composition and structure. However, results of empirical studies clearly show that even nests which are close to each other can be different both in terms of the species composition and abundance of Uropodina communities. So far, little is known about the factors that can cause these differences. The major aim of this study was to identify factors determining species composition, abundance, and community structure of Uropodina communities in mole nests. The study is based on material collected during a long-term investigation conducted in western parts of Poland. The results indicate that the two most important factors influencing species composition and abundance of Uropodina communities in mole nests are nest-building material and depth at which nests are located. Composition of Uropodina communities in nests of moles was also compared with that of other microhabitats (e.g. rotten wood, forest litter, soil) based on data from 4421 samples collected in Poland. Communities of this habitat prove most similar to these of open areas, especially meadows, as well as some forest types. PMID:26861069

    This paper evaluates long-term changes in the atmospheric depositions of S and N compounds, lake water quality, and biodiversity at eight glacial lakes in the Bohemian Forest over the past 130 years. This time interval covers (i) the 'background' pre-acidification status of the lakes, (ii) a period of changes in the communities that can be partly explained by introduction of fish, (iii) a period of strong lake acidification with its adverse impacts on the communities, (iv) the lake reversal from acidity, which includes the recent status of the lakes. The lake water chemistry has followed-with a characteristic hysteresis-both the sharp increase and decline in the deposition trends of strong anions. Remarkable changes in biota have mirrored the changing water quality. Fish became extinct and most species of zooplankton (Crustacea) and benthos (Ephemeroptera and Plecoptera) retreated due to the lake water acidification. Independent of ongoing chemical reversal, microorganisms remain dominant in the recent plankton biomass as well as in controlling the pelagic food webs. The first signs of the forthcoming biological recovery have already been evidenced in some lakes, such as the population of Ceriodaphnia quadrangula (Cladocera) returning into the pelagial of one lake or the increase in both phytoplankton biomass and rotifer numbers in another lake.

    Wastewater treatment plants (WWTP) receive the effluents from various sources (communities, industrial, and hospital effluents) and are recognized as reservoir for antibiotic-resistance genes (ARGs) that are associated with clinical pathogens. The aquatic environment is considered a hot-spot for horizontal gene transfer, and lake sediments offer the opportunity for reconstructing the pollution history and evaluating the impacts. In this context, variation with depth and time of the total bacterial load, the abundance of faecal indicator bacteria (FIB; E. coli and Enterococcus spp. (ENT)), Pseudomonas spp., and ARGs (blaTEM, blaSHV, blaCTX-M, blaNDM, and aadA) were quantified in sediment profiles of different parts of Lake Geneva using quantitative PCR. The abundance of bacterial marker genes was identified in sediments contaminated by WWTP following eutrophication of the lake. Additionally, ARGs, including the extended-spectrum ß-lactam- and aminoglycoside-resistance genes, were identified in the surface sediments. The ARG and FIB abundance strongly correlated (r ≥ 0.403, p < 0.05, n = 34) with organic matter and metal concentrations in the sediments, indicating a common and contemporary source of contamination. The contamination of sediments by untreated or partially treated effluent water can affect the quality of ecosystem. Therefore, the reduction of contaminants from the source is recommended for further improvement of water quality. PMID:25933054

    Underground nests of Talpa europaea, known as the common mole, are very specific microhabitats, which are also quite often inhabited by various groups of arthropods. Mites from the suborder Uropodina (Acari: Mesostigmata) are only one of them. One could expect that mole nests that are closely located are inhabited by communities of arthropods with similar species composition and structure. However, results of empirical studies clearly show that even nests which are close to each other can be different both in terms of the species composition and abundance of Uropodina communities. So far, little is known about the factors that can cause these differences. The major aim of this study was to identify factors determining species composition, abundance, and community structure of Uropodina communities in mole nests. The study is based on material collected during a long-term investigation conducted in western parts of Poland.

    A group of 46 leading environmental health scientists from 15 nations unanimously agreed to join forces in a new scientific effort to protect human health around the world from the potentially harmful effects of environmental chemicals and radioactive materials. The scientists agreed to establish a non-political European-based, not-for-profit organization whose objectives will be to promote, coordinate and fund environmental health research in order to provide a scientific basis for environmental remediation. The organization will be affiliated with the Conte Institute. The research priorities decided upon for Eastern and Central Europe were as follows: 1. Research into the effects of toxic metals, such as lead, cadmium, arsenic, and beryllium. 2. Research in the populations of the region on cancer, birth defects, and other diseases, with emphasis on data sharing across national boundaries, on quality control, and on use of biomarkers of reproductive and other effects. 3. Studies on the molecular, biochemical, and chromosomal bases for varying genetic susceptibilities to environmentally-induced diseases. 4. Coordination of research on radiation effects, especially on radiation-exposures resulting from nuclear power and weapons plants. 5. Research on approaches to bioremediation. 6. Education and training of professionals and nonprofessionals in environmental health issues, on an international basis. These and other issues will be taken up over time by this new, cooperative scientific research organization, as decided at the Prague Conference.

    The emotional consequences of fatherhood are markedly conditional on the context in which fatherhood is lived out. This study examines the association between different contemporary forms of fatherhood and paternal psychological well-being. The data are from an anonymous online survey of 3615 biological fathers, stepfathers, adoptive fathers, and foster fathers across the German-speaking countries of Central Europe. First, a detailed characterization of the different existing family constellations is provided. Second, the consequences of these different contemporary forms of fatherhood for paternal psychological well-being are investigated. Fathers of all ages (M = 40.11, range: 19-72) with at least one child under the age of 18 were included in the present analysis (N = 2785). The presented findings demonstrate that a family structure consisting of two biological parents with biological children seems to be most beneficial to paternal well-being, while some other forms of contemporary fatherhood are associated with impaired well-being, independently of sociodemographic or relationship aspects. More specifically, a history of family separation in non-residential biological fathers and blended-family fathers, and the concomitant loss of father-child contact, is shown to be particularly disadvantageous for the well-being of these fathers. Shared living arrangements, maintaining regular contact with biological children, or forming a new intact family could protect these fathers from negative outcomes. PMID:27679796

    Since the beginning of agriculture during the Neolithic Revolution, many phases of agricultural expansion and regression occurred with associated land clearance and reforestation. As a result, soil has been washed downslope by soil erosion and gullies have incised, leading to the development of colluvial and alluvial deposits in many areas worldwide. While an increasing number of studies on past soil erosion shows significant loss of soil as an effect of human activity and extreme rainfall events, only little is known about the knock-on effects on soil fertility, possibly triggering crop failures and land abandonment until the beginning of the coordinated research programmes on soil conservation. Based on historical documents and literature reviews this paper gives examples on how soil erosion had been perceived previously by farmers, land owners, researches, and policy makers in central Europe and south-eastern USA. It presents different types of problem solving strategies and their long term efficiency - a helpful tool to evaluate the long term effects of current soil conservation practices under changing climatic conditions and increasing land use pressure.

    Concentrations of polycyclic aromatic hydrocarbons (PAHs), polychlorinated biphenyls (PCBs), and chlorinated pesticides (CPs) were measured in air and precipitation at a background site in central Europe. Σ PAH concentrations in air and rainwater ranged from 0.7 to 327.9 ng m-3 and below analytical method detection limit (< MDL) to 2.1 × 103 ng L-1. The concentrations of PCBs and CPs in rainwater were < MDL. Σ PCB and Σ CP concentrations in air ranged from < MDL to 44.6 and < MDL to 351.7 pg m-3, respectively. The potential relationships between PAH wet scavenging and particulate matter and rainwater properties were investigated. The concentrations of ionic species in particulate matter and rainwater were significantly correlated, highlighting the importance of particle scavenging process. Overall, higher scavenging efficiencies were found for relatively less volatile PAHs, underlining the effect of analyte gas-particle partitioning on scavenging process. The PAH wet scavenging was more effective when the concentrations of ionic species were high. In addition, the elemental and organic carbon contents of the particulate matter were found to influence the PAH scavenging.

    Little is known about atmospheric input of beryllium (Be) into ecosystems, despite its highly toxic behavior. For three consecutive winters (2009-2011), we measured Be concentrations in horizontal deposition (rime) and vertical deposition (snow) at 10 remote mountain-top locations in the Czech Republic, Central Europe. Beryllium was determined both in filtered waters, and in HF digests of insoluble particles. Across the sites, soluble Be concentrations in rime were 7 times higher, compared to snow (6.1 vs. 0.9ng·L(-1)). Rime scavenged the pollution-rich lower segments of clouds. The lowest Be concentrations were detected in the soluble fraction of snow. Across the sites, 34% of total Be deposition occurred in the form of soluble (bioavailable) Be, the rest were insoluble particles. Beryllium fluxes decreased in the order: vertical dry deposition insoluble>vertical dry deposition soluble>horizontal deposition soluble>vertical wet deposition insoluble>vertical wet deposition soluble>horizontal deposition insoluble. The average contributions of these Be forms to total deposition were 56, 21, 8, 7, 5 and 3%, respectively. Sites in the northeast were more Be-polluted than the rest of the country with sources of pollution in industrial Silesia.

    Metamorphosed and deformed tourmaline-bearing leucogranites with a Cambro-Ordovician formation age are widespread in the Monotonous Group of the Variscan southern Bohemian Massif, Czech Republic. The rocks, known locally as Blaník gneiss, are strongly peraluminous and classify as phosphorus-rich low-T, S-type granite. The magma formed from a metapelitic source, most likely through muscovite dehydration melting. With respect to its low-T origin and the abundance of tourmaline, the Blaník gneiss is exotic within the spectrum of Early Palaeozoic granites of the Variscan fold belt of Central Europe. Coeval granitic gneisses in the neighbouring Gföhl unit of the Bohemian Massif can be classified as higher T S-type granites and were probably generated through biotite dehydration melting. The geochemical differences between the Early Palaeozoic granitic magmatism in the Gföhl unit and the Monotonous Group support models claiming that these two geological units belonged to independent peri-Gondwana terranes before the Variscan collision. It is suggested here, that the Gföhl unit and the Monotonous Group represent zones of higher and lower heat flow within the Early Palaeozoic northern Gondwana margin, respectively. The geochemical data presented in this study could be helpful for terrane correlations and palaeogeographic reconstructions.
