  9. Microalgal biofilms on common yew needles in relation to anthropogenic air pollution in urban Prague, Czech Republic.

    PubMed

    Nováková, Radka; Neustupa, Jiří

    2015-03-01

    Excessive occurrence of microalgae on needles of gymnosperms was reported for the first time in the 1980s from the Scandinavian countries. Since then, it has been repeatedly encountered on needles from various European forest habitats. The abundance of these biofilms has been related to the climatic conditions, such as temperature and precipitation, as well as to the air pollution by nitrogen and sulfur oxides. Urban areas typically have relatively homogenous climates and profound variation in levels of air pollution. Therefore, variation in the occurrence of biofilms in localities within an urban area may be related to local anthropogenic air pollution. We investigated the abundance of biofilms occurring on needles of the common yew (Taxus baccata) in the city of Prague, Czech Republic. The biofilms were composed of algae, fungi and particulate matter. The cover area of the biofilms was marginally explained by a positive influence of short-term maximum atmospheric levels of nitrogen dioxide (NO2). The amounts of the microalgae were also positively influenced by short-term maximum NO2 levels. In addition, high atmospheric levels of particulate matter (PM10) were related to low abundance of algae. The microbial biofilms growing on widely cultivated conifers, such as the common yew, form one of the few commonly occurring natural communities in highly urbanized central areas of temperate European cities. Consequently, we propose that microscopic analysis of biofilms may be used as a rapid and cheap method to collect ecological data. Such data may be used in biomonitoring schemes illustrating the effects of anthropogenic air pollution on natural microcommunities in urban areas.

    The prevalence of intestinal parasites was evaluated by examination of dog faecal samples in the Prague city centre, agricultural areas, and two shelters. The overall prevalence of parasites (i.e., protozoa and helminths, mentioned below) in Prague was 17.6%. Toxocara canis was the most common parasite, and was recovered from 6.2% of dogs, followed by Cystoisospora spp. (2.4%), Cryptosporidium spp. (1.4%), Trichuris sp. (1.1%), Taenia-type (1.0%), Giardia spp. (0.1%), Toxascaris sp. (0.9%), Dipylidium sp. (0.7%), Sarcocystis spp. (0.6%), Capillaria spp. (0.6%), Neospora/Hammondia spp. (0.5%), Ancylostoma sp. (0.4%), Uncinaria sp. (0.4%), and Spirocerca sp. (0.2%). The prevalence of infections with helminths and protozoans in two animal shelters in Prague was examined at the dog's admittance ir reception to the shelters and during housing. T. canis eggs (6.5%), Cystoisospora (4.4%), and Giardia (3.3%) cysts were the most prevalent. Significant increases in the prevalence of some parasites were found after a stay in the shelter. Giardia spp. showed an 11-fold increase in prevalence of dogs placed in the shelters for a longer time; Cryptosporidium spp. had a 7-fold increase, Capillaria spp. a 5-fold, Spirocerca sp., Neospora/Hammondia spp., and Cystoisospora spp. a 4-fold increase over dogs examined at the time of admittance to the shelter (p<0.01). Dog in rural areas were infected significantly more frequently (p<0.01) than those in Prague. In 540 faecal samples from rural areas, the overall prevalence of parasites (i.e., protozoa and helminths mentioned below) was 41.7%. The prevalence of T. canis was 13.7%, followed by Cystoisospora spp. (8.0%), Taenia spp. (3.5%), Sarcocystis spp. (3.0%), Giardia spp. (2.2%), Cryptosporidium spp. (2.0%), Trichuris sp. (1.7%), Toxascaris sp. (1.7%), Dipylidium sp. (1.3%), Neospora/Hammondia spp. (1.3%), Spirocerca sp. (1.1%), Uncinaria sp. (0.9%), Ancylostoma sp. (0.7%), and Capillaria spp. (0.6%).

    Opuka stone (extremely fine-grained clayey-calcareous silicite) used for a carved stone altar located in the interior of the St. Vitus Cathedral (Prague, Czech Republic) was affected by decay phenomena (formation of the case-hardened surface, its later blistering, flaking and/or powdering of stone substrate) which are similar to those observed in outdoor environments. Through the detailed analytical study (optical microscopy and scanning electron microscopy with energy dispersive spectrometry and x-ray elemental mapping of cross-sections of surface layers, x-ray diffraction of surface layers, ion-exchange chromatography for water-soluble salts, mercury porosimetry) and analysis of long-term indoor environmental monitoring (temperature, relative humidity, sulphur and nitrogen oxides deposition), it has been found that observed decay phenomena, which are manifested on microscale by brittle damage and formation of mode I (tensile) cracks along the exposed surface of the stone, can be interpreted as a result from thermohygric stress occurring on the interface between case hardened surface layer and stone substrate.

    The 6(th) Haemophilia Global Summit was held in Prague, Czech Republic, in September 2015. The programme was designed by an independent Scientific Steering Committee of haemophilia experts and aimed to share optimal management strategies for haemophilia at all life stages, explore recent potential advances in the management of haemophilia A and B and discuss challenges in haemophilia care. In this supplement from the meeting, Dan Hart reviews the lessons that can be learnt from cost-constrained environments with regard to improving care for people with haemophilia globally. Sébastien Lobet discusses the importance of physical activity for optimising care and Roseline d'Oiron and Jan Blatný consider the role of real-world data in understanding the effect of treatment in a clinical setting over the long term and the true impact of treatment on the day-to-day life of the patient. Gili Kenet addresses the current challenges relating to the optimal management of prophylaxis, and Gerry Dolan and Cedric Hermans discuss the value of pharmacokinetic (PK) parameters in informing treatment decisions. Cedric Hermans and Valérie Libotte explore the importance of considering social and occupational development factors as an integral part of haemophilia care, and Jan Astermark reviews key strategies to predict and prevent inhibitor development.

  13. Application of spatial synoptic classification in evaluating links between heat stress and cardiovascular mortality and morbidity in Prague, Czech Republic

    2015-09-01

    Spatial synoptic classification (SSC) is here first employed in assessing heat-related mortality and morbidity in Central Europe. It is applied for examining links between weather patterns and cardiovascular (CVD) mortality and morbidity in an extended summer season (16 May-15 September) during 1994-2009. As in previous studies, two SSC air masses (AMs)—dry tropical (DT) and moist tropical (MT)—are associated with significant excess CVD mortality in Prague, while effects on CVD hospital admissions are small and insignificant. Excess mortality for ischaemic heart diseases is more strongly associated with DT, while MT has adverse effect especially on cerebrovascular mortality. Links between the oppressive AMs and excess mortality relate also to conditions on previous days, as DT and MT occur in typical sequences. The highest CVD mortality deviations are found 1 day after a hot spell's onset, when temperature as well as frequency of the oppressive AMs are highest. Following this peak is typically DT- to MT-like weather transition, characterized by decrease in temperature and increase in humidity. The transition between upward (DT) and downward (MT) phases is associated with the largest excess CVD mortality, and the change contributes to the increased and more lagged effects on cerebrovascular mortality. The study highlights the importance of critically evaluating SSC's applicability and benefits within warning systems relative to other synoptic and epidemiological approaches. Only a subset of days with the oppressive AMs is associated with excess mortality, and regression models accounting for possible meteorological and other factors explain little of the mortality variance.

  14. Refining the Early Devonian time scale using Milankovitch cyclicity in Lochkovian-Pragian sediments (Prague Synform, Czech Republic)

    The Early Devonian geological time scale (base of the Devonian at 418.8 ± 2.9 Myr, Becker et al., 2012) suffers from poor age control, with associated large uncertainties between 2.5 and 4.2 Myr on the stage boundaries. Identifying orbital cycles from sedimentary successions can serve as a very powerful chronometer to test and, where appropriate, improve age models. Here, we focus on the Lochkovian and Pragian, the two lowermost Devonian stages. High-resolution magnetic susceptibility (χin - 5 to 10 cm sampling interval) and gamma ray spectrometry (GRS - 25 to 50 cm sampling interval) records were gathered from two main limestone sections, Požár-CS (118 m, spanning the Lochkov and Praha Formations) and Pod Barrandovem (174 m; Praha Formation), both in the Czech Republic. An additional section (Branžovy, 65 m, Praha Formation) was sampled for GRS (every 50 cm). The χin and GRS records are very similar, so χin variations are driven by variations in the samples' paramagnetic clay mineral content, reflecting changes in detrital input. Therefore, climatic variations are very likely captured in our records. Multiple spectral analysis and statistical techniques such as: Continuous Wavelet Transform, Evolutive Harmonic Analysis, Multi-taper method and Average Spectral Misfit, were used in concert to reach an optimal astronomical interpretation. The Požár-CS section shows distinctly varying sediment accumulation rates. The Lochkovian (essentially equivalent to the Lochkov Formation (Fm.)) is interpreted to include a total of nineteen 405 kyr eccentricity cycles, constraining its duration to 7.7 ± 2.8 Myr. The Praha Fm. includes fourteen 405 kyr eccentricity cycles in the three sampled sections, while the Pragian Stage only includes about four 405 kyr eccentricity cycles, thus exhibiting durations of 5.7 ± 0.6 Myr and 1.7 ± 0.7 Myr respectively. Because the Lochkov Fm. contains an interval with very low sediment accumulation rate and because the Praha Fm. was

    Palaeozoic limestones from the Barrandian area (Prague Basin, Bohemian Massif, Czech Republic) have been quarried and utilized, among others, for manufacturing of inorganic binders. Certain beds, e.g. Devonian dvorecko-prokopské limestones were historically burnt for high quality hydraulic lime which is not produced recently. Aiming to evaluate potential of this specific raw material for small-scale production of restoration hydraulic lime, we have conducted some laboratory experimental burning tests in an electrical furnace up to 1200°C. Prior to the burning, all studied lithotypes (4 in total) have been examined for their mineralogy (optical microscopy, cathodoluminescence study, X-ray diffraction of insoluble residue) and geochemistry (wet chemical analyses). Studied biomicritic limestones can be classified as wackstones to packstones. Carbonate content varies from 80 to 90 %, the rest is due to dominant illite and silica, and subordinate kaolinite, feldspars, and/or chlorite. Specific composition of non-carbonate component (specifically high content of illite and silica) positively influences formation of CS, Ca, and/or CAS phases when burnt at calcination temperatures from 850 to 1200°C (in steps of 50°C). In the products formed during firing, mineral phases typical for hydraulic lime, such as larnite, brownmillerite, and gehlenite, along with free lime, quartz and silica phases, and portlandite were identified by X-ray diffraction. The amount of the dominant hydraulic phase, larnite, increased with higher firing temperature. On the other hand, content of free lime, quartz and silica decreased. The amount of portlandite was almost independent of the firing temperature. Higher amounts of larnite and other hydraulic phase were detected during the peak firing temperature of 1200°C in specimens containing higher amount of insoluble residue. From the study performed, it is evident that studied dvorecko-prokopské limestone, which included favourable amount of

  20. Influence of mineralogical, petrographical, and geochemical characteristics of impure limestones on the composition of fired hydraulic lime: a case study on Lower Palaeozoic limestones from the Prague Basin (Barrandian area, Czech Republic)

    2014-05-01

    Prague Basin, making part of the Barrandian area (Bohemian Massif, Czech Republic), is a rift-like depression filled with non-metamorphosed sedimentary series of Upper Proterozoic - Lower Palaeozoic age. Among other sedimentary rocks, different types of limestones are present. These limestone were historically exploited and used for various purposes including natural and decorative stone, common construction material, and also a raw material for firing of inorganic binders: aerial lime, hydraulic lime and/or, more recently, Ordinary Portland Cement (OPC). Lithotypes with higher amount of silica and/or clay component were of special interest due to the hydraulicity of fired product known as "pasta di Praga" in Baroque. However, our recent knowledge of these limestones is incomplete in terms of the contribution of mineralogical, geochemical, and petrographical characteristics on the properties of fired hydraulic lime. In the recent study, representative samples of 4 facies of the Lower Devonian limestone (Kosoř ls., Řeporyje ls., Dvorce-Prokop ls., and Zlíchov ls.) were subjected to a detailed mineralogical and petrographic study of raw material by means of polarizing microscopy, cathodoluminiscence of thin sections and scanning electron microscopy with an energy dispersive spectrometer (SEM-EDS). X-ray diffraction (XRD) of insoluble residues obtained by treatment with both the hydrochloric acid and the acetic acid solution was used. Wet silicate analysis provided data on the content of major elements from which standard cement and lime indexes and modules were calculated. Laboratory firing experiments of these limestone were performed by a calcination at temperature ranging from 850 to 1200°C (after 50°C). XRD of fired products shows that limestones with high content of silica (some of the Dvorce-Prokop ls.) produced binder with high amount of newly formed calcium silicates (larnite). Gehlenite and others calcium aluminates and aluminosilicates are typical for

    Reports maintaining that sperm concentration in male ejaculates had decreased markedly over the past decades captured mind-share all over the world. However, literary data diverge about such a lasting trend. Our objective has been to contribute to the ongoing debate by presenting results of our own research. We have studied semen analyses of 5,363 men who had been tested at an outpatient care unit of the Prague Institute of Sexology between 1950 and 1984. These semen analyses measured volume of the ejaculate, sperm concentration, sperm motility, and a share of sperms with morphological abnormalities. None of these values showed statistically significant deterioration among seven groups of patients, each spanning five years. Therefore, our data did not confirm the above-mentioned lasting trend in semen analysis values. Research teams from all over the world have recently attracted a lot of attention by reporting a no-table decrease over the past decades in sperm concentration in the male ejaculates. However, literary data diverge about such a lasting trend. Our objective has been to contribute to the ongoing debate by presenting results of our own research. We have analysed semen tests filed in the archives of the Institute of Sexology at the 1st Faculty of Medicine of Charles University. We have studied a set of 5,363 men who had undergone their first sperm analysis between 1950 and 1984. We have gathered our data from medical records, using a uniform pattern of investigation. The set was divided into seven five-year groups based on the year of the first analysis. Volume of the ejaculate: The groups showed the following average volume of the ejaculate: 3.9-3.8-3.8-3.8-3.8-3.7-3.7 (ml). Neither the distribution nor the mean value of this variable has changed much over time. Sperm concentration: The groups showed the following mean sperm concentration: 32.9-42.3-56.2-57.9-72.2-70.8-72.3 (million per ml). It is obvious from these results that the mean sperm

The operational and personal costs of CzechGeo/EPOS are mostly covered by the Ministry of education, sports and youth within the support of twelve large research infrastructures in the Czech Republic. Web pages of the project www.czechgeo.cz are being built as a data portal which should integrate all the data and services provided by the involved institutions and research infrastructures. Seismic portal offers selected portions of digital data from permanent, local and temporary seismic stations, locations of seismic events in the country and worldwide, daily seismograms from permanent observatories and local seismic network Webnet, seismic bulletins and catalogs, and macroseismic observations on the territory of the Czech Republic. Magnetic portal involves besides real-time magnetograms also recent state of geomagnetic activity and its forecast for the next day. GPS portal will provide preprocessed data from regional GPS stations. Building the national portal is closely related with the development of the Preparatory phase of the EPOS (European Plate Observing System) project.

    Today, an agreement was signed in Prague between ESO and the Czech Republic, aiming to make the latter become a full member of ESO as of 1 January 2007. "The future membership of the Czech Republic in ESO opens for the Czech astronomers completely new opportunities and possibilities. It will foster this discipline on the highest quality level and open new opportunities for Czech industry to actively cooperate in research and development of high-tech instruments for astronomical research," said Miroslava Kopicová, Minister of Education, Youth and Sports of the Czech Republic. ESO PR Photo 52/06 ESO PR Photo 52/06 Signing Ceremony "We warmly welcome the Czech Republic as the thirteenth member of ESO," said Catherine Cesarsky, ESO's Director General. "The timing couldn't be better chosen: with the Very Large Telescope, Europe is now at the forefront of ground-based astronomy, and with the construction of ALMA and the final studies for the European Extremely Large Telescope, we will ensure that this will remain so for several decades. We look forward to working together with our Czech colleagues towards these successes." The signing event took place at the Czech Ministry of Education, Youth and Sports in Prague. Following ratification by the Czech Parliament, the Czech Republic with thus join the twelve present member states of ESO, the European Organisation for Astronomical Research in the Southern Hemisphere: Belgium, Denmark, France, Finland, Germany, Italy, the Netherlands, Portugal, Spain, Sweden, Switzerland and the United Kingdom. The Czech Republic is the first country from Central and Eastern Europe to join ESO. Astronomy in the Czech Republic has a very long tradition that dates from as far back as 3500 BC. Four centuries ago, Tycho Brahe and Johannes Kepler established themselves in Prague at the invitation of the emperor Rudolph II, laying the ground for the first golden age in astronomy. Later, eminent scientists such as Christian Doppler, Ernst Mach and

    At the 1st Medical Faculty of Charles University in Prague the prevalence of smoking was investigated among the faculty, staff, students and among health professionals in the country. We found 38.1% smokers (current and occasional) among malephysicians (N = 625), 25.6% smokers among women physicians (N = 394), 48.7% smoking nurses (N = 729) and 42.3% smokers among paramedical staff (N = 298). We have also followed up smoking habits among our students since 1989 (N = 1235). The number of smokers among them rose from 7% in 1989 to 18% in 1994. Students were also asked about their opinion on smoking as a risk factor for coronary heart disease which has a rising trend. Trying to coordinate the anti-smoking activity at all seven medical faculties in the Czech Republic, in collaboration with the Faculty of Medicine of Masaryk University in Brno, the National Centre for Health Promotion and the Czech Commission of EMASH, present the main points of the anti-smoking strategy at Czech medical faculties.

  16. Calibration of historical geomagnetic observations from Prague-Klementinum

    2015-04-01

    The long tradition of geomagnetic observations on the Czech territory dates back to 1839, when regular observations were started by Karl Kreil at the Astronomical Observatory Prague-Klementinum. Observations were carried out manually, at the beginning more than ten times per day and the frequency later decreased to 5 daily observations. Around the turn of century the observations became to be disturbed by the increasing urban magnetic noise and the observatory was closed down in 1926. The variation measurements were completed by absolute measurements carried out several times per year. Thanks to the diligence and carefulness of Karl Kreil and his followers all results were printed in the yearbooks Magnetische und meteorologische Beobachtungen zu Prag and have thus been saved until presence. The entire collection is kept at the Central Library of the Czech Academy of Sciences. As the oldest geomagnetic data have been recently recognized as an important source of information for Space Weather studies, digitization and analysis of the data have been now started. Although all volumes have been scanned with the OCR option, the low quality of original books does not allow for an automatic transformation to digital form. The data were typed by hand to Excel files with a primary check and further processed. Variation data from 1839 to 1871 were published in measured units (scales of divisions). Their reduction to physical units was not as straight forward as we are used in recent observatories. There were several reasons: (i) the large heavy magnetic rods were not as stable as recent systems, (ii) the absolute measurements of horizontal components were carried out by the genius but rather complicated Gauss method, (iii) the intervals between absolute measurements was on the scale of months and eventual errors were not recognized timely. The presentation will discuss several methods and give examples how to cope with the problem.

    These are the proceedings of the 30th Winter Workshop on Nuclear Dynamics, which was held in Galveston, Texas, in April 2014. As in previous years, the unique character of this conference series has allowed us to bring together nuclear scientists with very different interests to discuss recent progress and scientific achievements. Out of the 67 contributions at WWND 2014 we have selected these 34 manuscripts. The topics capture the range of theoretical and experimental advances in our field. On the experimental side we saw very exciting results from the RHIC beam energy scan program and the p-p, p-Pb and Pb-Pb runs at the highest collision energies at the LHC. On the theory side the system size dependence of the experimental measurements led to a detailed evaluation of the initial conditions and plasma propagation using a wide variety of phenomenological approaches. These results were complemented by the most recent continuum extrapolated data from lattice in order to model the complete evolution of the relativistic heavy ion system. These proceedings of the 30th Winter Workshop on Nuclear Dynamics again provide a snapshot of the status of the field. The articles, many of which were written by some of the most promising young scientists in the field, are documenting the excitement and achievements that are characteristic for modern day nuclear science.

  18. Kepler as astronomical observer in Prague

    NASA Astrophysics Data System (ADS)

    Bialas, Volker

    Official histories of science have consistently perpetuated the rumour that Kepler's poor eyesight prevented him from undertaking astronomical observations. However the condition of his eyesight could not have been so serious for in 1582, when his father made it possible for him to see a lunar eclipse, Kepler saw the moon emerge clearly. We find quite a lot of his astronomical observations especially of the years in Prague, mostly left in his manuscripts and unpublished until now. They will be edited in Vol. XXI.1 of the Kepler-Edition in the next future. Kepler's astronomical observations in Prague were mostly initiated by spectacular phenomena in the sky. He was self-critical enough to know, that his observations could not compete with those of the best observers of his time. It was not necessary for him to come up to highest standard of accuracy, and it was not possible to do so because he did not possess proper astronomical instruments. But nevertheless it was important for him as a theorist of astronomy and as a philosopher of nature to take a view of the phenomena which he wished to study carefully.

    A miniature lightweight portable Raman spectrometer and a palm-sized device allow for fast and unambiguous detection of common gemstones mounted in complex jewels. Here, complex religious artefacts and the Ring Monstrance from the Loreto treasury (Prague, Czech Republic; eighteenth century) were investigated. These discriminations are based on the very good correspondence of the wavenumbers of the strongest Raman bands of the minerals. Very short laser illumination times and efficient collection of scattered light were sufficient to obtain strong diagnostic Raman signals. The following minerals were documented: quartz and its varieties, beryl varieties (emerald), corundum varieties (sapphire), garnets (almandine, grossular), diamond as well as aragonite in pearls. Miniature Raman spectrometers can be recommended for common gemmological work as well as for mineralogical investigations of jewels and cultural heritage objects whenever the antiquities cannot be transported to a laboratory.This article is part of the themed issue 'Raman spectroscopy in art and archaeology'.

    Temperature inversions (TIs) have been closely studied for a variety of reasons. Here, we present an analysis of low-level TIs, based on a dataset of atmospheric soundings from the aerological station at Prague-Libuš (Czech Republic). Measurements have been carried out here since 1974, at the four main synoptic hours. First, the homogeneity of both the radiosonde data and sounding-derived time series was investigated. Since the homogeneity of the derived time series was affected by changes in the observation routine, only the period of 1992-2012 was further analysed. Second, diurnal and annual regimes of surface-based (SBTIs) and elevated (ETIs) temperature inversions were described. Maximum frequency of the SBTIs occurred at 00 UTC and in September and October. During autumn, persistent SBTIs also often occurred, which could be linked to decreased cyclonicity. Third, changes in TIs were evaluated, and the strongest trends were compared with the nearby station at Kümmersbruck (Germany). In all seasons except spring, nocturnal SBTIs decreased almost identically at both stations. Morning SBTIs decreased as well; however, the trend was considerably stronger at Prague; and it was also mirrored by an increase in ETIs. Since only a part of these trends could be explained by changes in the large-scale circulation, other factors (low tropospheric warming, suburbanisation) are hypothesized to have affected the trends.

    A number of epidemiological studies in several countries have implicated cigarette smoking, occupation, age, sex and air pollution as well as other environmental factors in the epidemiology of chronic respiratory disease. This paper reports the results of a respiratory-symptom and pulmonary-function survey among a large population of men aged 50-65 years in Prague. In general, the findings of other studies have been confirmed, showing that these relationships occur in an even wider range of geographic and cultural backgrounds. In addition, the study uncovered an apparent relationship between the occurrence of respiratory symptoms and a family history of chronic bronchitis and tuberculosis, suggesting that future surveys should include studies of familial aggregations of chronic respiratory disease. Similar studies have been carried out in other parts of Czechoslovakia with different levels of air pollution for comparison with the results of this study. PMID:5311058

    Prague, the Czech Republic, is a popular sex tourism destination where sex work is decriminalized and young men offer sexual services at low prices relative to countries in Western Europe. This quantitative survey aimed to identify some of the demographic characteristics of these young men and their experiences in the sex industry. Internet escorts (N = 20) and sex workers in bars and clubs (N = 20) completed the survey anonymously in spring 2011. The results showed that sex workers in clubs often had troubled pasts and were forced into sex work to survive. They also reported incidents of violence, serious alcohol and drug use, as well as frequent gambling. The larger group of sex workers in Prague is made up of Internet escorts who have backgrounds that are not atypical for the average Czech youth. They had fewer problems with drugs and alcohol but were twice as likely as sex workers in bars and clubs to be victims of violent crime. Plans for interventions to help those who would change their line of work, as well as the importance of sociocultural context in understanding sex workers, are discussed.

The 25th anniversary of Inverse Problems was celebrated with a service to the community, the publication of an issue of topical reviews selected by board members, which presented the achievements and state-of-the-art of the field. The 30th birthday of the journal is now approaching and we found it appropriate to include in the celebration the scientific community that supports the journal by their submissions. A conference, IPTA 2014: Inverse Problems - From Theory to Application (http://ipta2014.iopconfs.org/home), will be held in the home town of our publisher, IOP Publishing, in Bristol on 26-28 August 2014. The conference brings together top researchers, both from academia and industry, and will look at the scientific future of the field. Presentations by keynote speakers, which summarize what the board considers to be new trends, are complemented by contributions submitted by specialists and younger researchers in several minisymposia. To build a bridge to the future generation of researchers, a scientist at the beginning of their career will be giving a lecture. Let me finish with cordial thanks to all of our authors, referees, the members of the Editorial Board and International Advisory Panel, and the publishing team. I wish all of you a successful and healthy New Year and hope to meet many of you in August in Bristol.

    The European Commission, in its strategy to protect the health of the European citizens, states that in order to assess the impact of air pollution on public health, information on long-term exposure to air pollution should be available. Currently, indicators of air quality are often being generated using measured pollutant concentrations. While air quality monitoring stations data provide accurate time series information at specific locations, air quality models have the advantage of being able to assess the spatial variability of air quality (for different resolutions) and predict air quality in the future based on different scenarios. When running such air quality models at a high spatial and temporal resolution, one can simulate the actual situation as closely as possible, allowing for a detailed assessment of the risk of exposure to citizens from different pollutants. AURORA (Air quality modelling in Urban Regions using an Optimal Resolution Approach), a prognostic 3-dimensional Eulerian chemistry-transport model, is designed to simulate urban- to regional-scale atmospheric pollutant concentration and exposure fields. The AURORA model also allows to calculate the impact of changes in land use (e.g. planting of trees) or of emission reduction scenario's on air quality. AURORA is currently being applied within the ESA atmospheric GMES service, PASODOBLE (http://www.myair-eu.org), that delivers information on air quality, greenhouse gases, stratospheric ozone, … At present there are two operational AURORA services within PASODOBLE. Within the "Air quality forecast service" VITO delivers daily air quality forecasts for Belgium at a resolution of 5 km and for the major Belgian cities: Brussels, Ghent, Antwerp, Liege and Charleroi. Furthermore forecast services are provided for Prague, Czech Republic and Bratislava, Slovakia, both at a resolution of 1 km. The "Urban/regional air quality assessment service" provides urban- and regional-scale maps (hourly resolution

    Widimský, J

    2013-06-01

    The paper presents the origins of the Czech Society of Cardiology on the one hand, and the origins of Czech cardiology on the other. The Czech Society of Cardiology is the third oldest in the world (after the American and German Societies). It was founded in 1929 by Prof. Libenský. As early as in 1933, the Society organised the first international congress of cardiologists in Prague, which was attended by 200 doctors, out of which 50 were from abroad. The most participants came from France and Poland. Other participants came from England, Argentina, Belgium, the Netherlands, Italy, Romania, Spain and Switzerland. The worldwide importance of this congress is apparent from the fact that both the World Society of Cardiology and the European Society of Cardiology (EKS) were founded after World War II in the years 1950 and 1952, i.e. almost 20 years after the first international congress of cardiology in Prague. In 1964, the Fourth Congress of European Society of Cardiology was held in Prague with the participation of 1,500 specialists from 31 countries and chaired by Prof. Pavel Lukl, the later president of EKS (1964- 1968). The paper also presents the work of our specialists in WHO and the history of the international journal Cor et Vasa issued by the Avicenum publishing house in Prague in English and Russian in the years 1958- 1992. An important role in the development of our cardiology was played by certain departments and clinics. In 1951, the Institute for Cardiovascular Research (ÚCHOK) was founded in PrahaKrč, thanks to the initiative of MU Dr. František Kriegl, the Deputy Minister of Health. Its first director was Klement Weber, who published, as early as in 1929, a monograph on arrhythmias -  50 years earlier than arrhythmias started to be at the centre of attention of cardiologists. Klement Weber was one of the doctors of President T. G. Masaryk during his serious disease towards the end of his life. Jan Brod was the deputy of Klement Weber in the

    Geophysical studies on the Bush River Peninsula in the Edgewood Area of Aberdeen Proving Ground, Maryland, delineate landfill areas and provide diagnostic signatures of the hydrogeologic framework and possible contaminant pathways. These studies indicate that, during the Pleistocene Epoch, alternating stands of high and low seal levels resulted in a complex pattern of shallow channel-fill deposits in the Kings Creek area. Ground-penetrating radar studies reveal a paleochannel greater than 50 ft deep, with a thalweg trending offshore in a southwest direction into Kings Creek. Onshore, the ground-penetrating radar data indicate a 35-ft-deep branch to the main channel, trending to the north-northwest directly beneath the 30th Street Landfill. Other branches are suspected to meet the offshore paleochannel in the wetlands south and east of the 30th Street Landfill. This paleochannel depositional system is environmentally significant because it may control the shallow groundwater flow regime beneath the site. Electromagnetic surveys have delineated the pre-fill lowland area currently occupied by the 30th Street Landfill. Magnetic and conductive anomalies outline surficial and buried debris throughout the study area. On the basis of geophysical data, large-scale dumping has not occurred north of the Kings Creek Disposal Site or east of the 30th Street Landfill.

    Physical activity is the basic non-pharmacological instrument in the treatment of type 2 diabetes. Nevertheless, only a small number of diabetics take regular physical exercise. One of the reasons why diabetics "do not exercise" is that they have little opportunity to try physical stress under expert supervision and to get to know its effects on, for example, sugar levels. It is a very complex matter to define the optimal intensity of physical activity of, for example, a diabetic who suffers from obesity. In 2001 VSTJ MEDICINA Prague opened its first physical activity centre at the First Faculty of Medicine, Charles University in Prague, in cooperation with the Third Internal Clinic and the Institute of Sports Medicine of the First Faculty of Medicine, Charles University in Prague. It now has over 2000 members, of whom around 60% are patients with metabolic syndrome. Over 150 patients exercise every day under the supervision of expert instructors. The main objective of the Physical Activity Centre is to teach patients the correct principles of physical exercise to enable them to continue carrying out their trainers' instructions at home. A correct understanding of the importance of physical exercise and practical experience under the supervision of experienced instructors improves compliance and has a strong effect on the compensation of diabetes, thereby improving the prognoses of these patients.

    Intercomparison exercises of radon instruments play an important part when it comes to domestic survey as well as international or national mapping in dwellings, soil or water. Therefore, it is of prime interest to improve and standardize technical methods of measurement and also to verify quality assurance through comparison between different instruments and techniques. In the present paper is described the latest intercomparison exercise performed between the Laboratory of Environmental Radioactivity (hereafter called LER) of our department and other 15 different teams around Europe. The test has been held at two radon reference sites located 60 km SW of Prague, Czech Republic.

    High Energy Nuclear Physics (HENP) collaborations experience show that the computing resources available at a single site are often neither sufficient nor satisfy the need of remote collaborators eager to carry their analysis in the fastest and most convenient way. From latencies in the network connectivity to the lack of interactivity, work at distant computing centers is often inefficient. Having fully functional software stack on local resources is a strong enabler of science opportunities for any local group who can afford the time investment. The situation becomes more complex as vast amount of data are often needed to perform meaningful analysis. Prague's heavy-ions group participating in STAR experiment at RHIC has been a strong advocate of local computing as the most efficient means of data processing and physics analyses. To create an environment where science can freely thrive, a Tier 2 computing center was set up at a Regional Computing Center for Particle Physics called 'Golias'. It is the biggest farm in the Czech Republic fully dedicated for particle physics experiments. We report on our experience in setting up a fully functional Tier 2 center leveraging the minimal locally available human and financial resources. We discuss the solutions chosen to address storage space and analysis issues and the impact on the farms overall functionality. This includes a locally built STAR analysis framework, integration with a local DPM system (a cost effective storage solution), the influence of the availability and quality of the network connection to Tier 0 via a dedicated CESNET/ESnet link and the development of light-weight yet fully automated data transfer tools allowing the movement of entire datasets from BNL (Tier 0) to Golias (Tier 2). We will summarize the impact of the gained computing performance on the efficiency of the local physics group at offline physics analysis and show the feasibility of such a solution that can used by other groups as well.

    2013-04-01

    Several studies have examined heat- and cold-related cardiovascular (CVD) mortality in the Czech Republic. Much less is understood about heat- and cold-related CVD morbidity and possible regional differences. This study compares heat- and cold-stress effects on excess CVD mortality and morbidity in the city of Prague and a rural region of southern Bohemia over 16-year period (1994-2009). Population size and age structure are similar in the two regions. Excess mortality (number of deaths) and morbidity (number of hospital admissions) were determined as differences between observed and expected daily values, the latter being adjusted for long-term changes, annual and weekly cycles, and epidemics of influenza/acute respiratory infections. Several methods for identifying days and spells of days with heat and cold stress are applied, including Physiologically Equivalent Temperature (PET) and the Universal Thermal Climate Index (UTCI). Generally higher relative excess CVD mortality on warm days was identified in Prague, while on cold days we found higher excess CVD mortality in the rural region of southern Bohemia. In contrast to mortality, weak excess CVD morbidity was observed for both warm and cold days. The differences between Prague and the rural region of southern Bohemia indicate a possible influence of urban heat island effect in Prague together with other factors such as long- and short-term exposure to air pollution, different lifestyle, or different population, which may result in differing vulnerability to heat and cold stress.

He was one of the founders of gastroenterology in Czechoslovakia. He had been habilitated in 1948 for thesis Ulcerative colitis. Mařatka stood at the first steps of foundation of Czech Gastroenterology Society very soon after the WW2 and followed with the preparation as a secretary ge-neral of the 8th ASNEMGE Congress in Prague 1968 and as a president the 1st Congress of Endoscopy in the very optimistic atmosphere of ,,Prague Spring". He was nominated or elected by several international gastroenterology organisations, during 1976-1980 had been President of ESGE. He started with editoring of Czech gastroenterology Association journal as a member of editorial board and had been its main editor between 1969-1999. His well appreciated novelty in the magazine was a short remarks in one or two sentences from the world scientific literature which appeared in every copy. As an editor emeritus he supported the quality of the journal by many advices and contributions including articles.

    Documentary evidence is employed to present the history of tornadoes in the Czech Lands (recently Czech Republic) in AD 1119-2010. Based on contemporaneous descriptions of events, tornadoes are categorised as proven or probable. They are analysed collectively in terms of their spatio-temporal changes, annual variation, specific features, and impacts according to the Enhanced Fujita (EF) scale. The first documented tornado, on 30 July 1119, did great damage to Vyšehrad Castle in Prague (EF3). Only three other tornadoes were recorded before AD 1500. In the following three centuries, the number fluctuated between 11 and 16 events per century. Documented tornado frequency increased significantly from the 19th century onwards, reaching peaks in 1931-1940 (44 tornadoes) and particularly in 2001-2010 (56 tornadoes); this rise, however, reflects the availability of relevant sources as well as increased social awareness and advances in communication technology. A total of 264 tornado days and 307 tornadoes were documented for the Czech Lands in 1119-2010. Although they are relatively homogeneously extended over the territory of the Czech Republic, tornadoes tend to occur more frequently at lower and medium altitudes. The highest frequency of tornadoes is recorded for the summer half-year (mainly from June to August), although they may develop between March and October. Probable tornadoes have also been recorded in the winter months. The strongest tornadoes in the Czech Lands may be classified as EF3, largely with significant damage to buildings and trees, but 13 related deaths have also been recorded. The paper presents not only a new chronology and climatology for Czech tornadoes but is also an important contribution to the study of tornadoes in Europe.

    Summary Aim The rates of HIV acquired through heterosexual contact are increasing in the Czech Republic. This study explored potential HIV risk associations with alcohol, illicit drugs and sexual behaviours among adults from a community-based sample attending gay- and non-gay venues in Prague. Methods Women attending bars, cafes and beer gardens in central Prague responded to the self-administered, time-site survey. Alcohol use was measured by the AUDIT-C and CAGE questionnaires. Sexual network structuring identified number, gender and coital frequency with current and recent sexual partners. Statistical analysis included central tendency, chi-square and logistic regression. Female participants (n = 124) ranged from 18 to 67 years of age (mean 29 years); 25% self-identified as non-heterosexual. Results We found alcohol to be the preferred drug of choice. Younger heterosexual women with new and casual sexual partners were more likely to use alcohol excessively. Women with children reported the least alcohol use. Sixty percent of the sample had never used condoms; condom-use was associated with longer relationship duration and discussions about HIV status with a sexual partner; non-use tended to occur among unmarried women with multiple male partners in short, serial sexual relationships. Women who sought HIV testing tended to be younger and more self-identified as non-heterosexual. Protective practices were rarely reported even when HIV transmission increases via heterosexual sexual partnering. Conclusion Further research is recommended regarding cultural and contextual influences on HIV risk behaviours among Czech women. PMID:26851424

  13. Born unwanted, 35 years later: the Prague study.

    A long-held belief among mental health practitioners is that being born unwanted carries a risk of negative psychosocial development and poor mental health in adulthood. The Prague Study was designed to test this hypothesis. It followed the development and mental well-being of 220 children (now adults) born in 1961-63 in Prague to women twice denied abortion for the same unwanted pregnancy. The children were individually pair-matched at about age nine with 220 children born from accepted pregnancies when no abortion had been requested. This article brings together in one place the theoretical assumptions and hypotheses, the criteria for selecting the study participants and major findings from five follow-up waves conducted among the children around the ages of 9, 14-16, 21-23, 28-31 and 32-35 years, plus a sub-study of married unwanted pregnancy subjects and accepted pregnancy controls at ages 26-28. To control for potential confounding factors in data interpretation, all siblings of all subjects were included in the last two waves. It was found that differences in psychosocial development widened over time but lessened at around age 30. All the differences consistently disfavoured the unwanted pregnancy subjects, especially only children (no siblings). They became psychiatric patients (especially in-patients) more frequently than the accepted pregnancy controls and also more often than their siblings. The overall findings suggest that, in the aggregate, denial of abortion for unwanted pregnancy entails an increased risk for negative psychosocial development and mental well-being in adulthood.

    Extraordinary occasions for art of any kind - music, creative graphic and plastic arts, literature (classic, modern incl. science fiction), theatre, cinema, etc. - exist to harmonise individual personal interests with those of the humanity well-being and of the Nature and also to cultivate individual spirituality and the appropriate values. Arts can be applied as irreplaceable means for making any human being better, for improving his sense for solidarity and for increasing his ethical sensibility. An interest for the art should be cultivated already since the childhood. - How much of inspiration for numerous composers all over the world has been given by the Nature, how much of inspiration for people who by listening to such a music are increasing nobility of their behaviour as well as their friendly approach to the Nature. - Many classical music works have been written with a strong inspiration by the Nature itself from the past until today. The actual Year of the Czech Music gives the possibility to present the most famous Czech composers inspired by the Nature (selected examples only): Bedřich Smetana (1824 - 1884): At the sea shore - a concert etude for piano inspired by his stay in Göteborg (Sweden); Vltava (Moldau) - a symphonic poem from the cycle "My country" inspired by the river crossing Bohemia from the South to Prague; From the Bohemian woods and meadows - another symphonic poem from the same cycle. Antonín Dvořák (1841 - 1904): V přírodě (In the Nature) - a work for orchestra Leoš Janáček (1854 - 1928): Příhody li\\vsky Bystrou\\vsky (The Cunning Little Vixen) - an opera situated mostly in a forest. Josef Bohuslav Foerster (1859-1951): Velké širé rodné lány (Big large native fields) - a choir for men singers inspired by the nature in the region where the composer as a boy from Prague was visiting his grand-father. Vítězslav Novák (1870 - 1949): In Tatra mountains - a symphonic poem expressing the author's passion for the famous

    2016-04-01

    Reduced numbers of deaths during heat waves related to introduction of heat early warning systems has been demonstrated in many areas of the world. These systems are most often based on synoptic or epidemiological approaches to assessing the impact of heat on mortality. While the synoptic approach is based on the classification of air masses and the subsequent identification of oppressive air masses (OAMs), the epidemiological approach identifies direct relationship between time series of mortality and meteorological data (mostly air temperature). In this study, OAMs and oppressive days (ODs) will be identified in the period May-September 1994-2013 using selected methods of the synoptic (SSC) and epidemiological approach (GAM, piecewise regression), respectively. Relations between mortality daily data (adjusted for long-term and seasonal changes) and both meteorological and non-meteorological factors (pollution, day of the season, the length of heat waves, year) within OAMs and ODs, will be identified in the "training" years. The resulting regression relationships will be tested on independent "testing" years to evaluate the ability of different approaches to predict days with increased mortality. The results of the project may help to refine the criteria for issuing biometeorological forecasts and warnings of possible adverse heat effects.

    The 16th volume of the Acta Historica Astronomiae is the Proceedings of the International Symposium on the History of Science in the Rudolphine Period. The meeting was held in Prague from 22 to 25 October 2001, on the 400th anniversary of Tycho's sudden death, and was attended by approximately 65 scientists and historians. The volume contains 36 contributions dealing with the life and work of Tycho Brahe, the astronomy of the era, and many cultural aspects of Rudolphine Prague. One of the first papers is an eye-opener on the fact that Tycho Brahe was a cosmologically-driven observer. This is followed by a very illuminating paper on gender roles in science in the late 16th century, with emphasis on the role of Sophie Brahe, Tycho's youngest sister. Several subsequent papers reveal the existence of barely known links between Tycho and his contemporaneous colleagues. These extremely-well documented papers also deal with the broader philosophical investigation he was involved in, viz. meteorology, medicine, astrology, alchemy and even theology. Important names of Tycho's days are Petrus Severinus, Johannes Pratensis, Theophrastus Paracelsus, John Craig, Ursus (Nicolai Reymers Baer) etc. Very illuminating is the information on the relations between Tycho and the Jesuits in Prague, explaining the reason why this order was very supportive of the Tychonic cosmological model. The relationsship with Kepler, and also Kepler's observational activities (after Tycho's death) are highlighted as well as the hideous mode of communication between Galileo and Kepler. More than one paper deals with the accuracy and precision of Tycho's observations, and the causal impact of this accuracy on the scientific revolution. Another study discusses the study of Tycho's handwriting, this paper brings the aditional bonus of a list of accessible works which contain notes by him. One very interesting project was Brahe's proposal to the Republic of Venice to determine the exact latitudes of

    Uterus transplantation is a novel experimental method of female infertility treatment. It is an appropriate treatment modality for women with absolute uterine factor infertility - congenital uterine malformations, absent uterus, hysterectomized women and non-functional uterus.Successful animal studies confirming the safety and efficacy were performed before introduction of uterus transplantation into human medicine. The first clinical trial was performed in 2012-2013 in Gothenburg, Sweden. The first child from the transplanted womb was delivered in 2014. Concerning the promising results of Swedish trial it is essential to perform trials in some other world centers.In 2015 Czech Ministry of Health permitted uterus transplantation trial in cooperation of two Prague hospitals - namely Institute for Clinical and Experimental Medicine and University Hospital Motol. The aim of the Czech trial is to reassert feasibility, efficacy and safety of uterus transplantation in two groups of women - 10 recipients from living and 10 from deceased brain donor. We believe that detailed and precise long-term theoretic and practical preparation and perfectly arranged trial are the main conditions of the successful uterine transplantation survey. The first Czech uterus transplantation was performed in April 30, 2016.Up to December 2016 four transplantations out of planned 20 (2 in living donor and 2 in deceased brain donor arm) were carried out by our team.

    Human skeletal variability is influenced by several factors, including genetics, environment, and socio-cultural background. Forensic methods being traditionally based on targeted reference groups, it is recognized that they are population-specific. Additionally, secular trends highly impact on the skeletal morphology, but the effect of outdated methods on forensic cases is not yet well documented. This paper compares the sexual dimorphism of femoral dimensions in two samples from the Czech population separated by 60 years in time (Pachner and the Prague National Museum Collections). Significant secular trends are present within this short span in both sexes and for most of the seven tested linear variables. The consequence of secular trends on sex determination is tested with logistic regression, and a decrease in reliability is systematically observed when using the older Czech sample on the 20th century sample, whichever the set of variables included. A model based on a recent Croatian sample provides a higher reliability on contemporaneous Czech individuals. These results imply that above population specificity, temporal consistency may be a major criterion to fulfil when applying forensic anthropology identification methods.

    Report is given on the tuberculosis (TB) prevalence and the new diseases monitoring in Czech Republic (CR) in 1999 using the register of notifiable TB diseases. 1631 new TB cases and relapse were notified (15.9/100,000 citizens). Majority TB cases, 1369 (13.3/100,000 citizens) were of the respiratory system and 262 TB cases were in other locations. 63% of the respiratory system diseases were bacteriologically verified. In comparison with the year 1998, the number of newly notified TB patients was 9.6% lower, number of TB cases of the respiratory system which were bacteriologically verified was 12.3% lower, cases of microscopically positive TB were 17.4% less frequent. Among the notified TB patients there were 91 foreigners. TB relapse was identified in 61 patients. Among the notified TB cases, 987 (60.5%) were males and 644 (39.5%) were females. In both sexes patients over 65 predominated. Prevalence of TB cases higher than the average for the whole state was found in Prague, northern and western Bohemia. Groups with TB prevalence higher than 50/100,000 citizens were identified (the risk groups). They include homeless people, drug addicts, asylum applicants, and prisoners. Due to subjective troubles of patients TB was diagnosed in 70.2% cases, by active investigation in 13.9% patients. Late TB diagnosis at autopsy came in 6.8% cases. Decease due to TB was notified in 79 patients. In 77 of them TB had not been diagnosed premortally. 106 new cases and relapses of non-TB mycobacterial disease were notified in 1999. The case of tuberculosis in CR was in 1999 restrainable. In comparison with 1998 significant decrease of TB prevalence in individual subgroups of TB disease was described (10 to 17%). Also the decrease of the long-term trend (10 years) of newly notified TB patients and TB of the respiratory system was depicted. It is necessary to maintain the quality and extend of the TB control program in order to prevent the new outbreak of TB disease.

    Computing Center of the Institute of Physics in Prague provides computing and storage resources for various HEP experiments (D0, Atlas, Alice, Auger) and currently operates more than 300 worker nodes with more than 2500 cores and provides more than 2PB of disk space. Our site is limited to one C-sized block of IPv4 addresses, and hence we had to move most of our worker nodes behind the NAT. However this solution demands more difficult routing setup. We see the IPv6 deployment as a solution that provides less routing, more switching and therefore promises higher network throughput. The administrators of the Computing Center strive to configure and install all provided services automatically. For installation tasks we use PXE and kickstart, for network configuration we use DHCP and for software configuration we use CFEngine. Many hardware boxes are configured via specific web pages or telnet/ssh protocol provided by the box itself. All our services are monitored with several tools e.g. Nagios, Munin, Ganglia. We rely heavily on the SNMP protocol for hardware health monitoring. All these installation, configuration and monitoring tools must be tested before we can switch completely to IPv6 network stack. In this contribution we present the tests we have made, limitations we have faced and configuration decisions that we have made during IPv6 testing. We also present testbed built on virtual machines that was used for all the testing and evaluation.

    The usage of the new IPv6 protocol in production is becoming reality in the HEP community and the Computing Centre of the Institute of Physics in Prague participates in many IPv6 related activities. Our contribution presents experience with monitoring in HEPiX distributed IPv6 testbed which includes 11 remote sites. We use Nagios to check availability of services and Smokeping for monitoring the network latency. Since it is not always trivial to setup DNS in a dual stack environment properly, we developed a Nagios plugin for checking whether a domain name is resolvable when using only IP protocol version 6 and only version 4. We will also present local area network monitoring and tuning related to IPv6 performance. One of the most important software for a grid site is a batch system for a job execution. We will present our experience with configuring and running Torque batch system in a dual stack environment. We also discuss the steps needed to run VO specific jobs in our IPv6 testbed.

    Personal exposures to carcinogenic polycyclic aromatic hydrocarbons (c-PAHs) bound to airborne particulate matter 2.5 μm (PM2.5) were measured in the context of a large-scale molecular epidemiological study in order to identify the impacts of air pollution on human health. Sampling was carried out in three industrial cities in the Czech Republic: Ostrava, Karvina and Havirov. The city of Prague, exhibiting much lower industrial air pollution but a high level of traffic, served as a control. The first monitoring campaigns were held in winter and were repeated in the summer of 2009. The active personal monitors PV 1.7 for PM2.5-bound c-PAHs were used. Non-smoking city policemen from Prague, Karvina and Havirov, and office workers from Ostrava, participated in the study. All participants completed a personal questionnaire and a time-location-activity diary. The average personal winter exposure to c-PAHs (sum of the eight PAHs-benz[a]anthracene, benzo[a]pyrene, benzo[b]fluoranthene, benzo[g,h,i]perylene, benzo[k]fluoranthene, chrysene, dibenz[a,h]anthracene and indeno[1,2,3-c,d]pyrene) was highest in Karvina, 39.1, followed by Ostrava at 15.1 and Prague at 4.3 ng/m(3). The winter levels were significantly higher than the summer values (P<0.001): 4.3 in Karvina, 3.0 in Ostrava, 1.6 in Havirov and 1.0 ng/m(3) in Prague. The average personal benzo[a]pyrene winter/summer exposures were: 6.9/0.6 in Karvina, 2.5/0.4 in Ostrava, 0.8/0.1 in Prague and 0.2 ng/m(3) in summer in Havirov. In this study, we examined personal exposure to c-PAHs and tested it for associations with potential predictor variables collected from questionnaires, addressing life style factors and day-to-day activities. We found outdoor concentration, environmental tobacco smoke exposure, home heating fuel of coal, wood or gas, frequency of exhaust fan use, cooking and commuting by a car to be the main determinants of personal exposure.

  13. Aging in the Czech Republic.

    PubMed

    Andel, Ross

    2014-12-01

    The goal was to provide an overview of main issues relevant to aging in the Czech Republic. The Czech Republic is a former Eastern Bloc nation of about 10.5 million. Older adults are overrepresented relative to those under age 15. Life expectancy currently hovers around 78 years (75 for men/81 for women), a number slightly higher than most of Eastern Europe but lower than most of Western Europe. Cardiovascular diseases account for about 50% of all mortality, which is one of the highest rates in Europe and therefore of particular concern. Lifestyle habits, especially high alcohol consumption, a high rate of smokers, and high-fat diet relative to most other European countries and the United States, combined with relatively low expenditures for health promotion, appear important in the context of high cardiovascular mortality. Long-term care is funded mostly by state and local governments. The country has tried to address issues associated with insufficient capacity and low quality in long-term care, a particularly prominent problem in the Czech Republic compared with other European countries. The recently established International Clinical Research Center brings new possibilities for collaborative research in the Czech Republic, including research specific to aging. Improving long-term care and establishing methodologically sound longitudinal data sets are among the most pressing issues, although sustaining the pension system strained by increasing life expectancy, low retirement age, and extensive government-sponsored benefits has also recently emerged as a critical issue.

    Abstract Objective To assess risk factors for paediatric burn injuries in the Czech Republic and to suggest preventive measures. Methods This study included all children aged 0–16 years hospitalized during 1993–2000 at the Prague Burn Centre and data from the Czech Ministry of Health on national paediatric burn hospitalizations during 1996–2006. Personal, equipment and environmental risk factors were identified from hospital records. Findings The incidence of burn admissions among 0–14 year-olds increased from 85 to 96 per 100 000 between 1996 and 2006, mainly due to a 13% increase among 1–4 year-olds. Between 1993–2000 and 2006, the proportion of burn victims in the country hospitalized at the Prague Burn Centre increased from 9% to 21%. Detailed data were available on 1064 children (64% boys). Around 31% of all burn hospitalizations were in 1 year-olds. Some 79% of burns occurred at home: 70% in the kitchen, 14% in the living room or bedroom and 11% in the bathroom. Of the 18% occurring outdoors, 80% involved boys. Scalds from hot liquids accounted for 70% of all burns. The mean hospital stay was 22 days for boys and 18 days for girls. Conclusion Most burns involved scalds from hot liquids at home: beverages in kitchens and water in bathrooms. There is a need for passive preventive measures, such as redesigned domestic cooking and eating areas, safer electrical kettles and temperature control devices for bathrooms. Educational programmes should be developed for parents and caregivers. A national plan for child burn prevention with specific targets would be helpful. PMID:19551256

    This analysis of the Czech health system reviews recent developments in organization and governance, health financing, health-care provision, health reforms and health system performance. The Czech health-care system is based on compulsory statutory health insurance providing virtually universal coverage and a broad range of benefits, and doing so at 7.7 % of GDP in 2012 - well below the EU average - of which a comparatively high 85 % was publicly funded. Some important health indicators are better than the EU averages (such as mortality due to respiratory disease) or even among the best in the world (in terms of infant mortality, for example). On the other hand, mortality rates for diseases of the circulatory system and malignant neoplasms are well above the EU average, as are a range of health-care utilization rates, such as outpatient contacts and average length of stay in acute care hospitals. In short, there is substantial potential in the Czech Republic for efficiency gains and to improve health outcomes. Furthermore, the need for reform in order to financially sustain the system became evident again after the global financial crisis, but there is as yet no consensus about how to achieve this.

    Takasago has been devoted to producing l-menthol since 1954, and our long history of manufacturing this important aroma chemical is reviewed here. The current asymmetric catalytic process had its 30th anniversary in 2013. Our l-menthol process is considered carbon-neutral, and, therefore, 'green' and sustainable. It uses renewable myrcene obtained from gum rosin as a starting material. In addition, the Rh-BINAP (=2,2'-bis(diphenylphosphino)-1,1'-binaphthyl) catalytic system is highly efficient. This pathway not only leads l-menthol, but a variety of 100% biobased aroma chemical products as well. By measuring the (14) C levels in a material, one can determine the percentage of carbon that is biobased. This biobased assay, described as the ratio plant-derived C/fossil-derived C, can clarify how renewable a product really is. This will be highlighted for several of Takasago's key aroma chemicals.

    Life expectancy is increasing worldwide and the burden of Parkinson's disease (PD) is growing. There are several cost-of-illness studies for PD from Western Europe and the USA, however, data about the costs associated with PD in Eastern Europe are still lacking. The objective of this study was to evaluate direct and indirect costs in a cohort of Czech patients with idiopathic PD and to identify cost-driving factors. Study participants (n=100) were recruited from the neurological department of the Charles University in Prague. Health-economic data were collected using a "bottom-up" approach. Costs were calculated from the societal perspective and the human capital approach was used to estimate indirect costs. Czech currency was converted into 2004 Euros (EUR) and inflated to 2008 prices. Independent cost-driving factors were identified in multivariate regression analysis. Total semi-annual costs of PD were EUR 5510 (95% CI: 4470-7090) per patient. Direct costs accounted for 60% of the total costs and indirect costs for 40%. Patients' expenditures accounted for 40% of their income. Independent cost-driving factors included disease severity, motor complications, psychosis and age. In conclusion, our study demonstrates a considerable economic burden of PD in the Czech Republic. Total costs are generally lower than in Western Europe but the proportion of costs that fall on patients is higher because of lower incomes. More intensive government support for patients with chronic diseases such as PD and the development of disease-management programs that incorporate both the clinical and economic effects of PD treatment are needed.

    The history of early meteorological observations using instruments in the Czech Lands is described (the longest temperature series for Prague-Klementinum starts in 1775, precipitation series for Brno in 1803). Using the PRODIGE method, long-term monthly temperature and precipitation series from selected secular stations were homogenized (for 10 and 12 stations, respectively). All the seasonal and annual temperature series for the common period 1882-2010 show a significant positive linear trend with accelerated warming from the 1970s onwards. No significant linear trends were disclosed in the series of seasonal and annual precipitation totals. Correlation coefficients between the Czech series analysed decrease as distances between measuring stations increase. A sharper decrease of correlations for precipitation totals displays much weaker spatial relationships than those for mean temperatures. The highest correlations between all stations appeared in 1921-1950, the lowest in 1891-1920 (temperature) and 1981-2010 (precipitation). Wavelet analysis reveals that very distinct annual cycles, as well as the slightly weaker semi-annual ones, are better expressed for temperature series than for precipitation. Statistically significant cycles longer than one year are temporally unstable and sporadic for precipitation while in the temperature series cycles of 7.4-7.7a (a = year) and 17.9-18.4a were recorded as significant by all stations in 1882-2010 (quasi-biennial cycle of 2.1-2.2a for half the stations). Czech homogenous temperature series correlate best with those of the Northern Hemisphere for annual, spring and summer values (with significant correlation coefficients between 0.60 and 0.70), but this relation is temporally unstable. Circulation indices, such as the North Atlantic Oscillation Index (NAOI) and the Central European Zonal Index (CEZI) may explain the greater part of Czech temperature variability, especially from December to March and for the winter; however

    Several studies have examined the relationship of high and low air temperatures to cardiovascular mortality in the Czech Republic. Much less is understood about heat-/cold-related cardiovascular morbidity and possible regional differences. This paper compares the effects of warm and cold days on excess mortality and morbidity for cardiovascular diseases (CVDs) in the city of Prague and a rural region of southern Bohemia during 1994-2009. Population size and age structure are similar in the two regions. The results are evaluated for selected population groups (men and women). Excess mortality (number of deaths) and morbidity (number of hospital admissions) were determined as differences between observed and expected daily values, the latter being adjusted for long-term changes, annual and weekly cycles, and epidemics of influenza/acute respiratory infections. Generally higher relative excess CVD mortality on warm days than on cold days was identified in both regions. In contrast to mortality, weak excess CVD morbidity was observed for both warm and cold days. Different responses of individual CVDs to heat versus cold stress may be caused by the different nature of each CVD and different physiological processes induced by heat or cold stress. The slight differences between Prague and southern Bohemia in response to heat versus cold stress suggest the possible influence of environmental and socioeconomic factors such as the effects of urban heat island and exposure to air pollution, lifestyle differences, and divergence in population structure, which may result in differing vulnerability of urban versus rural population to temperature extremes.

    This paper bundles 40 contributions by the IceCube collaboration that were submitted to the 30th International Cosmic Ray Conference ICRC 2007. The articles cover studies on cosmic rays and atmospheric neutrinos, searches for non-localized, extraterrestrial {nu}{sub e}, {nu}{sub {mu}} and {nu}{sub {tau}} signals, scans for steady and intermittent neutrino point sources, searches for dark matter candidates, magnetic monopoles and other exotic particles, improvements in analysis techniques, as well as future detector extensions. The IceCube observatory will be finalized in 2011 to form a cubic-kilometer ice-Cherenkov detector at the location of the geographic South Pole. At the present state of construction, IceCube consists of 52 paired IceTop surface tanks and 22 IceCube strings with a total of 1426 Digital Optical Modules deployed at depths up to 2350 m. The observatory also integrates the 19 string AMANDA subdetector, that was completed in 2000 and extends IceCube's reach to lower energies. Before the deployment of IceTop, cosmic air showers were registered with the 30 station SPASE-2 surface array. IceCube's low noise Digital Optical Modules are very reliable, show a uniform response and record waveforms of arriving photons that are resolvable with nanosecond precision over a large dynamic range. Data acquisition, reconstruction and simulation software are running in production mode and the analyses, profiting from the improved data quality and increased overall sensitivity, are well under way.

  13. Life history of the individuals buried in the St. Benedict Cemetery (Prague, 15th-18th centuries): insights from (14)C dating and stable isotope (δ(13)C, δ(15)N, δ(18)O) analysis.

    Funerary practices and bioarchaeological (sex and age) data suggest that a mortality crisis linked to an epidemic episode occurred during the fifth phase of the St. Benedict cemetery in Prague (Czech Republic). To identify this mass mortality episode, we reconstructed individual life histories (dietary and mobility factors), assessed the population's biological homogeneity, and proposed a new chronology through stable isotope analysis (δ(13)C, δ(18)O and δ(15)N) and direct radiocarbon dating. Stable isotope analysis was conducted on the bone and tooth enamel (collagen and carbonate) of 19 individuals from three multiple graves (MG) and 12 individuals from individual graves (IG). The δ(15)N values of collagen and the difference between the δ(13)C values of collagen and bone carbonate could indicate that the IG individuals had a richer protein diet than the MG individuals or different food resources. The human bone and enamel carbonate and δ(18)O values suggest that the majority of individuals from MG and all individuals from IG spent most of their lives outside of the Bohemian region. Variations in δ(18)O values also indicate that all individuals experienced residential mobility during their lives. The stable isotope results, biological (age and sex) data and eight (14)C dates clearly differentiate the MG and IG groups. The present work provides evidence for the reuse of the St. Benedict cemetery to bury soldiers despite the funeral protest ban (1635 AD). The Siege of Prague (1742 AD) by French-Bavarian-Saxon armies is identified as the cause of the St. Benedict mass mortality event.

    The study resumes previous research that found significant effects of hot spells on increased mortality in highly urbanized regions of the Czech Republic, and declining trends in heat-related mortality in the Czech population as a whole. We analyze severe hot spells during 1994-2013 and temporal changes of their effects on total and cardiovascular mortality in several urban regions with a different overall socioeconomic level (city of Prague, city of Brno, Ostrava region, NW Bohemia). Mortality data were standardized to account for different population structure and its changes over time. The mortality baseline for each region was determined using a generalized additive model. Although declining trends in the mortality impacts of hot spells prevail in most regions in spite of rising temperature trends, the magnitude of the mortality decline was different with respect to the overall socioeconomic level and development of the regions. The results suggest that trends in heat-related mortality depend on the level of socioeconomic deprivation of population. It is essential to better understand the risks of climate change in different parts of population with respect to their adaptability.

    The physiological and molecular basis of apparent resistance to glyphosate in horseweed (Conyza canadensis L. Cronq.) plants that had survived being sprayed with the herbicide at Prague-Bubny railway station in the Czech Republic was investigated. For the sake of comparison, plants expected to be susceptible were collected in areas where no herbicides had been used. Plants of both sets were treated, at the rosette stage (10-25 leaves, diameter of 3-5 cm), with herbicide at the rate recommended for use in the Czech Republic to control horseweed (960 g of glyphosate-IPA/ha; Roundup Klasik, Monsanto, 480 g of glyphosate-IPA ae L(-1)). Phytotoxic symptoms of the treated plants varied substantially, both between and within these sets of plants. Leaves of susceptible (S) plants wilted and turned yellow, and the plants subsequently died; leaves of plants with reduced susceptibility (RS) remained green, or new leaves were created in the center of their rosettes a few weeks after glyphosate application. There were no significant differences in the accumulation of shikimate between S and RS plants 3 days after treatment (DAT). However, the time course of changes in shikimic acid contents differed between the two biotypes; from 3 to 10 DAT, they decreased more than 4-fold in RS plants, while in S plants, they increased (3-fold, on average) from 3 to 7 DAT. A conserved region of the epsps gene, in which mutations are known to confer resistance in several plant species, was amplified from samples of both S and RS plants and sequenced, but no changes in the encoded amino acid sequence were found, indicating that mutations at another epsps site were responsible for the observed resistance, or that the mechanism may be at least partially non-target-based. Our results suggest that the reduced susceptibility to glyphosate may be due to impaired herbicide translocation, as previously found in studies of horseweed in the United States.

    Viticulture has long been essential to the commercial and social well-being of parts of the Czech Lands (now the Czech Republic), and detailed records have been kept for centuries of the timing and relative success of the grape crop. Using such documentary data from the Bohemian wine-growing region (mainly northwest of the capital, Prague), series of grape-harvest dates (GHDs) were created for the 1499-2015 period. Because the link between harvest dates and temperatures is strong, GHD series, together with instrumental mean temperature series starting in 1801, were used to reconstruct mean April-August temperatures for the region from 1499 to 2015. Linear regression (LR) and variance scaling (VS) methods were used for calibration and compared in terms of explained variance and their ability to capture extreme values. It emerged that LR does not significantly underestimate temperature variability. However, VS shows far greater capacity to capture extremes. GHDs explain 64 % of temperature variability over the full calibration period. The 1986-2015 period was identified as the warmest 30-year period of the past 514 years, an observation consistent with recent global warming. The highest April-August temperatures appeared in a reconstruction for the year 1540, which was warmer than the next two very warm, and far more recent, seasons in 2003 and 2015. The coldest period occurred at the beginning of the 20th century (1900-1929). The series reconstructed for the Czech Lands is in close agreement with other (central) European reconstructions based on other proxies. The series created here makes an important contribution to a better understanding of long-term spatiotemporal temperature variability in central Europe.

    The main goal of personalized medicine is the individualized approach to the patient's treatment. It could be achieved only by the integration of the complexity of novel findings in diverse "omics" disciplines, new methods of medical imaging, as well as implementation of reliable biomarkers into the medical care. The implementation of personalized medicine into clinical practice is dependent on the adaptation of pre-graduate and post-graduate medical education to these principles. The situation in the education of personalized medicine in the Czech Republic is analyzed together with novel educational tools that are currently established in our country. The EPMA representatives in the Czech Republic in cooperation with the working group of professionals at the Faculty of Medicine in Pilsen, Charles University in Prague have implemented the survey of personalized medicine awareness among students of Faculty of Medicine in Pilsen-the "Personalized Medicine Questionnaire". The results showed lacking knowledge of personalized medicine principles and students' will of education in this domain. Therefore, several educational activities addressed particularly to medical students and young physicians were realized at our facility with very positive evaluation. These educational activities (conferences, workshops, seminars, e-learning and special courses in personalized medicine (PM)) will be a part of pre-graduate and post-graduate medical education, will be extended to other medical faculties in our country. The "Summer School of Personalized Medicine in Plzen 2015" will be organized at the Faculty of Medicine and Faculty Hospital in Pilsen as the first event on this topic in the Czech Republic.

  2. Were the 2011 Prague, Oklahoma Earthquakes Natural, Induced, or Something in Between?

    NASA Astrophysics Data System (ADS)

    McGarr, A.

    2013-12-01

    Two hypotheses have been proposed for the origin of the Prague, Oklahoma earthquake sequence, which is under debate. I offer a third explanation, whereby this sequence was triggered by approximately 12 million cubic m of wastewater injected into the epicentral zone, from five high-volume injection wells. This sequence included three earthquakes of M5 or greater: a M5 foreshock, the M5.7 main shock, and a M5 aftershock (Keranen et al., Geology, 2013). The main shock, which caused substantial damage, is of exceptional importance in the central and eastern United States because it is the second largest earthquake that has been recorded in this vast region. Because of its importance in assessing seismic hazard, especially in central Oklahoma, there is an urgent need to understand its origin. The first hypothesis argues that the Prague earthquakes are of natural origin (Keller and Holland, OGS website, 2013). As shown by Ellsworth et al. (abstract, SSA Meeting, 2012,), the seismicity in central Oklahoma has increased dramatically starting in 2009. This increase is inconsistent with natural processes that are likely to occur in this geologically stable area. Instead, it seems more likely that the increase in seismicity is related to the increase of fluid injection activities related to expanding oil and gas operations. Even so, the Prague earthquakes themselves could be a natural sequence. The second hypothesis argues that the M5 foreshock was triggered by pore pressure increase due to wastewater injected from two wells near the northeast end of the epicentral zone. This M5 event, in turn, increased the Coulomb stress on a pre-existing fault triggering the M5.7 mainshock and its numerous aftershocks (Keranen, et al., 2013). This hypothesis focuses on two nearly co-located disposal wells, Stasta 1 and 2, that together injected nearly 100,000 cubic m of wastewater into the basal aquifer during the years leading up to the Prague earthquakes. There are, however, five much

    Lead concentrations in the tissues of perch and its parasites were determined as mg/kg dw. Lead was found at higher concentrations in the acanthocephalans (11.56) than in different tissues (liver, gonads and muscle with skin and bone) of perch. With respect to fish tissues, the highest concentrations of lead were present in the liver (1.24), followed by the gonads (0.57) whereas the lowest concentrations were in the muscle with skin and bone (0.21). The bioconcentration factors for lead indicated that parasites accumulate metals to a higher degree than fish tissues--lead concentrations in acanthocephalans were 9.32, 19.27 and 55.05 higher than in liver, gonads and muscles of host, respectively.

    We monitored concentrations of Cd, Cu, Mn and Zn in acantocephalan parasites (Acanthocephalus lucii) and its final host (Perca fluviatilis). The concentrations in parasites were found to be significantly higher than those found in the muscle, gonads and liver of fish host. The bioaccumulation factor values were 194, 24.4, 2.2 and 4.7 for Cd, Cu, Mn and Zn, respectively. This suggests a benefit for the host due to the high accumulation of toxic cadmium.

    Drugs taken for cancer can interact with each other, with agents taken as part of supportive care, with drugs taken for comorbid conditions (which are particularly common in the elderly patients), and with herbal supplements and complementary medicines. We tend to focus on the narrow therapeutic window of cytotoxics, but the metabolism of tyrosine kinase inhibitors by the cytochrome P450 3A4 enzyme (CYP3A4) makes some TKIs particularly prone to interference with or from other agents sharing this pathway. There is also potential for adverse pharmacokinetic interactions with new hormonal agents used in advanced prostate cancer. PMID:26823680

    Totally 887 heifers of Holstein-Friesian breed mostly in late pregnancy imported to the Czech Republic from France (597), Germany (89), Denmark (181) and Holland (20) were examined coprologically from September 1993 to March 1995 in the parasitological laboratory of the National Veterinary Institute (NVI). Prague. Feces were sampled individually, rectally, always on days 1-3 following importation from heifers housed in particular quarantine sheds. In compliance with presently valid veterinary regulations, all animals were examined for liver fluke disease (fascioliasis) and lungworm. Moreover, 634 heifers were submitted to qualitative coprological examination aimed at revealing the presence of cysts and oocysts of protozoa, eggs of taenias and nematodes of gastrointestinal tract. The method according to Pavlásek (1991), especially designed for proving oocysts of the genus Cryptosporidium, was applied in all fecal specimens delivered to the SVI from animals in quarantine (N = 887). From trematodes, 12 heifers imported from France were positive for eggs of Fasciola hepatica and in other two animals eggs of the genus Paramphistomum were found. None of the imported heifers showed lungworm disease. Summary of data on occurrence of endoparasites gained during qualitative examination of samples of feces taken from heifers imported from France, Germany and Denmark is presented in Tab. I. Parasitologically, 91.2 to 100% of imported animals were positive. Taeniasis (the genus Moniezia) was detected in 2.8% of heifers imported from France and in 9.8% animals from Denmark. Protozoal parasites were found in 58.8% (Denmark) and 92.8% (Germany) heifers. Coccidial oocysts most frequently observed represented the genus Eimeria (E. bovis, E. auburnensis and E. zuernii). Gastrointestinal nematodes of nine genera were found in 72.5 to 80.8% of heifers. The most frequent findings were genera Ostertagia, Haemonchus and Trichostrongylus.

    Professor Frantisek Por MD and Professor Robert Klopstock MD were contemporaries, both born in 1899, one in Zvolen, the other in Dombovar, at the time of Austro-Hungarian Monarchy. Prof. Por attended the Faculty of Medicine in Budapest from 1918 to 1920, and Prof. Klopstock studied at the same place between 1917 and 1919. From 1920 until graduation on 6th February 1926, Prof. Por continued his studies at the German Faculty of Medicine, Charles University in Prague. Prof. Klopstock had to interrupt his studies in Budapest due to pulmonary tuberculosis; he received treatment at Tatranske Matliare where he befriended Franz Kafka. Later, upon Kafka's encouragement, he changed institutions and continued his studies at the German Faculty of Medicine, Charles University in Prague, where he graduated the first great go. It is very likely that, during their studies in Budapest and Prague, both professors met repeatedly, even though their life paths later separated. Following his graduation, Prof. Por practiced as an internist in Prague, later in Slovakia, and from 1945 in Kosice. In 1961, he was awarded the title of university professor of internal medicine at the Faculty of Medicine, Pavol Jozef Safarik University in Kosice, where he practiced until his death in 1980. Prof. Klopstock continued his studies in Kiel and Berlin. After his graduation in 1933, he practiced in Berlin as a surgeon and in 1938 left for USA. In 1962, he was awarded the title of university professor of pulmonary surgery in NewYork, where he died in 1972.

Normalization MS/Fe is also used to determine the contamination of sediments by magnetic particles, using calculation of enrichment factor of magnetic susceptibility in sediments. In our study, we compared the magnetic enrichment of overbank fines of five rivers in Czech Republic (the Ploucnice, the Morava, the Jizera, the Litavka, and the Berounka rivers). Magnetic susceptibility was measured using KLY-2 Kappabridge (Agico, Czech Republic) and mass-specific data were expressed in m3×kg-1. X-ray fluorescence elementary analysis of powdered sediments was performed by ED XRF MiniPal 4.0 (PANalytical, the Netherlands). ED XRF results were calibrated to ppm values using results obtained from selected samples by ICP MS. Compared samples were taken from lithogenic parts of profiles, unaffected by anthropogenic contamination and pedogenetic and reductimorphic processes. Results showed high variability of the measured values. In the Litavka and the Morava River sediments were measured low values of MS (˂150×10-9) at relatively high contents of Fe (20-45 000 ppm). In contrast, lower flow of the Jizera River showed low Fe contents (˂12000 ppm) having MS values in a wide range (70-800×10-9). The Plou

    Two criticality dosimetry systems were tested by Czech participants during the intercomparison held in Valduc, France, June 2002. The first consisted of the thermoluminescent detectors (TLDs) (Al-P glasses) and Si-diodes as passive neutron dosemeters. Second, it was studied to what extent the individual dosemeters used in the Czech routine personal dosimetry service can give a reliable estimation of criticality accident exposure. It was found that the first system furnishes quite reliable estimation of accidental doses. For routine individual dosimetry system, no important problems were encountered in the case of photon dosemeters (TLDs, film badge). For etched track detectors in contact with the 232Th or 235U-Al alloy, the track density saturation for the spark counting method limits the upper dose at approximately 1 Gy for neutrons with the energy >1 MeV.

    Cerny, M.

    1995-12-01

    On February 16, 1992, the Government of the Czech Republic sanctioned, by its Decree No. 112/82, its first Energy Policy. Since that time, a number of conditions have changed: first of all, there was the partition of the former Federal Czechoslovak Republic, then the privatization of most of energy producing corporations, the deregulation of a significant proportion of power and energy commodities, the decision to bring to an end the construction of the Temelin nuclear power station, the creation of conditions for the construction of the Ingoldstadt oil pipeline, etc. These steps, on which the final decisions have been made, have brought about the necessity of updating the existing general Energy Policy. The updated Energy Policy is based on the Programme Statement by the Government of the Czech Republic of July 1992, as well as on other materials associated with energy and power generation, either approved or negotiated by the Government, in particular the State Environmental Policy the Rules of the State Raw Materials Policy, the European Association Agreement, the European Energy Charter, the results of the Uruguayan Round of GATT, the Convention on Climate Changes, the Ecological Action Programme for central and East-European countries, and other international documents that have either been, or are likely to be sanctioned by the Czech Government (especially the European Energy Charter Treaty, and the protocol on Trans-boundary Air Pollution and on Further Reduction of Sulphur Oxide Emissions).

  17. Health tourism in a Czech health spa.

    PubMed

    Speier, Amy R

    2011-04-01

    This paper is about the changing shape of health tourism in a Czech spa town. The research focuses on balneotherapy as a traditional Czech healing technique, which involves complex drinking and bathing therapies, as it is increasingly being incorporated into the development of a Czech health tourism industry. Today, the health tourism industry in Mariánske Lázne is attempting to 'harmoniously' combine three elements--balneology, travel and business activities. One detects subtle shifts and consequent incongruities as doctors struggle for control over the medical portion of spa hotels. At the same time, marketing groups are creating new packages for a general clientele, and the implementation of these new packages de-medicalizes balneotherapy. Related to the issue of the doctor's authority in the spa, the changes occurring with the privatization of tourism entails the entrance of 'tourists' to Mariánske Lázne who are not necessarily seeking spa treatment but who are still staying at spa hotels. There is a general consensus among spa doctors and employees that balneotherapy has become commodified. Thus, while balneotherapy remains a traditional form of therapy, the commercial context in which it exists has created a new form of health tourism.

    The aims of this study were to evaluate seroprevalence and the importance of various risk-factors for Toxoplasma infection in the Czech Republic. A prospective cross-sectional survey was conducted among military personnel in Prague. Consenting subjects (n = 3250) completed a questionnaire concerning demographics and risk-factors, and blood samples were taken to determine anti-Toxoplasma antibody titres according to complement fixation and ELISA IgG and IgM tests. The seroprevalence of toxoplasmosis was 23%. In multivariate analysis, independent predictors of Toxoplasma seropositivity were age (OR 1.03 / year), consumption of raw meat (OR 1.35), owning a cat (OR 1.25), owning rabbits (OR 1.47), childhood residence in a town with a population of <10 000 inhabitants (OR 1.63) vs. location of the childhood residence in a town with population of >100 000 inhabitants, and blood group type A (OR 1.28), B (OR 1.33) or AB (OR 1.43) vs. O. These results suggested that horizontal toxoplasmosis transmission in the Czech Republic may occur through consumption of raw meat, contact with cat faeces and farming.

    Abstract A golden jackal (Canis aureus) individual was recorded ~40 km east of Prague in the Czech Republic. It is the first record of a living golden jackal in the country; up to now several individuals have been recorded but all of them were either shot dead or killed by a vehicle. The observed animal was documented by camera traps set up for research of carnivore diversity in different habitats in the study area. It was first photographed on 19 June 2015, and in total there were 57 records made by 12 traps until 24 March 2016 when the animal was still present in the area. Forty-nine of the 57 records were made in a shrubby grassland over an area of ~100 ha, 39% of sightings were during the day and 61% in the night. There were two distinct peaks in the circadian activity of the animal, from 4 to 10 a.m., and from 6 p.m. to midnight. We also review the verified records of the golden jackal in the Czech Republic, some of which were only published in local hunting magazines. However, the observation reported in this paper represents the first evidence of a long-term occurrence in Europe of the same golden jackal individual, that persisted for at least nine months and over winter, northwest of Hungarian-Austrian border where the population has been known to reproduce.

  20. Extreme wind climate in the Czech Republic

    Pop, L.; Hanslian, D.; Jiri, H.

    2011-12-01

    Extreme wind events belong to the most damaging weather-related hazards in Czech Republic. Therefore a complex survey is performed to exploit the wind data available over the period of industrial measurements in Czech Republic for extreme wind analysis. The object of the survey is to find the limitations of wind data available, to analyze the conditions for extreme wind events and to try to enhance the knowledge about the statistical behavior of extreme wind. The data quality showed itself as a major issue. The homogeneity of extreme wind data is broken in many cases as the extreme wind values are highly dependent on the measuring instrumentation and changes in neighborhood. It also may be difficult to distinguish between correct high wind data and erroneous values. The individual analysis and quality assessment of wind data used in extremal analysis is therefore essential. There are generally two basic groups of extreme wind events typical in the Czech Republic and generally over the mid-latitudes: The "convective" events (can be also called as "squalls") are primarily initiated by deep convection, whereas the primary cause for "non-convective" (synoptic) events is large-scale pressure gradient. The subject is, however, a bit more complex, as the pressure gradient inducing high wind in higher atmospheric levels or wind shear can be a significant factor in convective events; on the other hand, convection may increase wind speeds in otherwise "non-convective" synoptic-scale windstorms. In addition, there are some special phenomena that should be treated individually: the physical principle and climatological behavior (frequency, magnitude and area affected) of tornadoes make them very different from common convective straight winds; this is in lesser scale also the case of "foehn" or "bora" effects belonging to non-convective events. These effects, however, do not play major role over the Czech Republic. In Czech Republic, the overall impact of convective and non

    Preliminary results of research on old maps of Czech Lands deposited at the Map Collection of Charles University (CU) in Prague are presented. The extensive cartographic collection belongs among the most important collections in the Czech Republic. Maps of Czech Lands, i.e. Bohemia, Moravia and Silesia, created by individuals in the period of 1518 - 1720 are part of our history and represent important cultural heritage of immense value. They give evidence about the period in which they originated. The goal of the research is to document the development of cartography during the period 1518 (Claudianus's map) to 1720 (Müller's map). More than 50 originals or facsimiles of different maps were found in the Map Collection of CU during inventory phase of the work. This paper concentrates on a description of most interesting maps discovered from the point of view of their content, map symbols and cartometric characteristics. The research is conducted within the project "Cartometric and semiotic analysis and visualization of the old Czech Lands maps in the period 1518 - 1720". The analysis of map content can provide us with answers to other relevant questions related to analysis and assessment of maps. Similarly to modern maps, old maps also include some map elements which were becoming more and more precise with the development of cartography and geodesy. The map research then centered on the analysis of the map content and on cartometric analysis using modern computation methods. The obtained results of the research will be described and compared with information presented in historical and cartographic studies of the last decades. Cartometric analyses of the map are important. They verify cartographic parameters of the map. The following cartometric analysis will be carried out: positional accuracy of the map, calculation of the map scale, calculation of the rotation of the map. The methodology of cartometric analysis used in this article is based on comparing a

    AIM: To ascertain whether the Prague circumferential (C) length and maximal (M) length criteria for grading the extent of Barrett’s esophagus can be applied prior to its widespread application in South Korea. METHODS: Two hundred and thirteen consecutive cases with endoscopic columnar-lined esophagus (CLE) were included and classified according to the Prague C and M criteria. RESULTS: Of 213 cases with CLE, the distribution of maximum CLE lengths was: 0.5-0.9 cm in 99 cases (46.5%); 1.0-1.4 cm in 63 cases (29.6%); 1.5-1.9 cm in 15 cases (7.0%); 2.0-2.4 cm in 14 cases (6.6%); 2.5-2.9 cm in 1 case (0.5%); and 7.0 cm in 1 case (0.5%). Twenty cases (9.4%) had columnar islands alone. Two hundred and eight cases (97.7%) lacked the circumferential CLE component (C0Mx). Columnar islands were found in 70 cases (32.9%), of which 20 cases (9.4%) had columnar islands alone. CONCLUSION: In regions where most CLE patients display short or ultrashort tongue-like appearance, more detailed descriptions of CLE’s in < 1.0 cm lengths and columnar islands, as well as avoidance of repeating the prefix “C0” need to be considered in parallel with the widespread application of the Prague system in South Korea.

    1993-10-01

    The Prague Conference on nuclear waste management and environmental remediation provided extensive interchange of ideas and insight into new technologies and management approaches throughout the world. A variety of environmental remediation technologies have potential application to Department of Energy facilities; others illustrate pitfalls to be avoided. This paper presents the highlights from the first environmental remediation (ER) technical program in the American Society of Mechanical Engineers` series of international nuclear waste management conferences. This program covers ER technologies, decontamination and decommissioning (D&D) technologies and experience, ER site characterization and modeling, management of and results from actual clean up actions, and data on several major international environmental problems. Focusing on direct benefits to the Department of Energy`s (DOE) ER Program, this paper summarizes pertinent technical information, identifies useful technical papers, lists key technical contacts, and identifies specific actions to obtain additional information. US attendance at meetings like this is normally quite limited compared to attendance at North American meetings. The purpose of this paper then is to increase general awareness of this meeting in US technical circles and to broadly disseminate key information to US ER programs and contractors. To do this, the paper is organized to present background information on the conference itself, document the beneficial technical information, and outline ongoing information exchange activities.

    This paper presents the results from a field trial that was performed during a 4 year period on a 5.5 km long radio link path operating at 26 GHz in Prague. The purpose was to investigate the amount of attenuation due to precipitation and its yearly variations. The attenuation of the radio link signal and the rain rate were measured. The measured attenuation results are compared to the models given by the International Telecommunication Union (ITU). The propagation measurements show large yearly variations due to variability in rain rate from one year to another. The measured results are in agreement with the ITU long-term statistical rain attenuation model if the measured rain rate for the individual year is used. For the worst year the number of fades, the fade duration, the fade speed, the worst month statistics, and the polarization correlation are presented. The measurements presented will add to the current knowledge of fading due to precipitation, and some of the results, such as the fade duration distributions, are new knowledge.

    The purpose of this research was to compare ecological status of a few small urban watersheds in Prague agglomeration (the Botic creek, the Zátisský creek and the Komoranský creek) with different sources of pollution, different sewer systems and with different hydraulic regimes of the recipient. Concentrations of selected heavy metals (Cd, Cu, Ni, Pb, Zn) were measured in water and sediment samples and in different species of benthic organisms. The biological assessment of macrozoobenthos has also been carried out using two biotic indexes: the saprobic index and the ASPT. The assessment of the environmental risk in an aquatic environment has been based on three different coefficients: the Distribution coefficient (Kd), the Hazard Quotient (HQ) and the Metal Pollution Index (MPI). In the Botic creek there was found out chronic load of bottom sediment by heavy metals. There is higher ecological risk of sediment toxicity in this creek. Outlets of combined sewer system in the Botic creek degrade water quality and consequently deteriorate biological indicators. In the Zátisský creek the main problem is connected with storm sewer outlets. The comparison of the Zátisský creek with the reference stream, the Komoranský creek demonstrates strong hydraulic impact, which induces frequent changes of watercourse morphology reflecting on the composition and representation of benthic macroorganisms.

    ALICE, as well as the other experiments at the CERN LHC, has been building a distributed data management infrastructure since 2002. Experience gained during years of operations with different types of storage managers deployed over this infrastructure has shown, that the most adequate storage solution for ALICE is the native XRootD manager developed within a CERN - SLAC collaboration. The XRootD storage clusters exhibit higher stability and availability in comparison with other storage solutions and demonstrate a number of other advantages, like support of high speed WAN data access or no need for maintaining complex databases. Two of the operational characteristics of XRootD data servers are a relatively high number of open sockets and a high Unix load. In this article, we would like to describe our experience with the tuning/optimization of machines hosting the XRootD servers, which are part of the ALICE storage cluster at the Tier-2 WLCG site in Prague, Czech Republic. The optimization procedure, in addition to boosting the read/write performance of the servers, also resulted in a reduction of the Unix load.

    The results of atmospheric deposition of heavy metals and trace elements, determined in moss Pleurozium schreberi collected around the Temelin Nuclear Power Station in the Czech Republic in 2011, are presented. The monitored area around NPP Temelin comprises 29 sampling sites located along 8 profile radii stretched as of 2, 5, 10, and 20 km from the NPP. Some pollution sources are located in the study area. A total of 42 elements (Na, Mg, Al, Cl, K, Ca, Sc, Ti, V, Cr, Mn, Fe, Co, Ni, Zn, As, Se, Br, Rb, Sr, Zr, Mo, Ag, Cd, In, Sb, I, Cs, Ba, La, Ce, Sm, Eu, Tb, Hf, Ta, W, Au, Hg, Pb, Th, and U) were determined by epithermal instrumental neutron activation analysis with the neutron flux density Φepi=3.6×1011n/(cm2s) at the pulsed fast reactor IBR-2, FLNP, JINR. To determine the presence of radionuclides and their measurable activity in samples, laboratory gamma spectrometry was found to be the best detection method. A coaxial HPGe detector with samples in the geometry of Marinelli containers in the laboratory of Faculty of Nuclear Sciences CTU in Prague was used. To assess the influence of NPP Temelin on the Biomass in 20 km radius, the mass activity of 137Cs (Bq/kg) was determined. No other short-term radionuclides have ever been identified in any spectrum.

    The objective of this descriptive study was to evaluate the performance of the international World Health Organization (WHO) child growth standards in the Czech Republic and determine the prevalence of wasting among children using the 1991 Czech growth reference and the WHO growth standards. The study utilized the 2006 WHO Child Growth Standards and the 1991 Czech growth references. The WHO standards were based on a longitudinal study of 882 children aged 0-24 months and on cross-sectional studies of 6669 children aged 18-71 months. The 1991 Czech growth references were based on a cross-sectional survey including 90 910 children aged 0-18 years (34 164 were children aged < 5 years). The prevalence of wasting was significantly higher among Czech children when using the WHO growth standards compared with the Czech references. The prevalence of wasting among 0-5-month-old children was 15.5% among boys and 12.9% among girls compared with the expected 2.3% of the WHO standards. In the length category of 50 cm, 9.0% of boys and 9.9% of girls fell under the WHO wasting cut-off compared with the 3% from the Czech growth reference. The application of the WHO growth standards may results in a significant increase of Czech children classified in the category of wasting, especially among infants aged 0-5 months. The performance and potential impacts of the WHO growth standards should be evaluated further before their adoption in the Czech Republic and other countries with local growth references.

    2013-12-01

    Moderate sized earthquakes (~M5-6) in the continental interior of the United States are relatively rare. However, anthropogenic stresses, such as the injection of fluids associated with oil and natural gas extraction, act to weaken the continental crust and can cause the release of stresses through earthquakes along pre-existing faults. In November 2011, three M≥ 5.0 earthquakes occurred near Prague, Oklahoma along the Wilzetta fault system, a historically inactive, complex network of interacting strike-slip faults. These earthquakes were large enough to damage infrastructure in the epicentral region, including several homes, as well as injure two people. Thousands of earthquakes were generated along the Wilzetta fault system including the M5.0 foreshock, M5.7 mainshock, and M5.0 aftershock that occurred on November 5, 6 and 8, respectively. The M5.0 foreshock ruptured a NE-striking fault segment located within ~200 m of active injection wells and within ~1 km of the surface, and has been interpreted as an induced event [Keranen et al., 2013]. In the days to weeks that followed the M5.0 foreshock, we detected thousands of aftershocks with a dense network of 47 temporary stations, including seven seismometers that are part of the EarthScope Transportable Array. The stations are located both in the epicentral region and at regional distances of up to 150 km. The dense station distribution and vigorous aftershock sequence provide an opportunity to probe the local fault structures and stress field using shear wave splitting measurements. The orientation of polarized shear waves and the associated delay times, measured from the split shear waves, provide information on the anisotropy of the upper crust. Rotations of shear wave polarization may indicate variation in local pore fluid pressures that could potentially be linked to injection activity, near fault stress heterogeneity, and/or local shear fabric aligned with fault structures.

    2014-01-01

    The slip model for the 2011 Mw 5.6 Prague, Oklahoma, earthquake is inferred using a linear least squares methodology. Waveforms of six aftershocks recorded at 21 regional stations are used as empirical Green's functions (EGFs). The solution indicates two large slip patches: one located around the hypocenter with a depth range of 3–5.5 km; the other located to the southwest of the epicenter with a depth range from 7.5 to 9.5 km. The total moment of the solution is estimated at 3.37 × 1024 dyne cm (Mw 5.65). The peak slip and average stress drop for the source at the hypocenter are 70 cm and 90 bars, respectively, approximately one half the values for the Mw 5.8 2011 Mineral, Virginia, earthquake. The stress drop averaged over all areas of slip is 16 bars. The relatively low peak slip and stress drop may indicate an induced component in the origin of the Prague earthquake from deep fluid injection.

    Human prion diseases are a group of very rare diseases with a unique pathogenesis and, due to an inauspicious prognosis and unavailability of therapy, with fatal consequences. The etiopathogenetic background is the presence of pathologically misfolded prion protein, highly resistant to denaturation, the aggregation and presence of which in the brain tissue causes irreversible neuronal damage. The most frequent prion disease in humans is Creutzfeldt-Jakob disease (CJD) which occurs in sporadic, hereditary/familial, or acquired/infectious/iatrogenic forms. A new form of CJD, variant CJD, is considered to be linked to dietary exposure to beef products from cattle infected with bovine spongiform encephalopathy (BSE) and to infection via blood transfusion. The clinical picture of these diseases is characterized by a rapidly progressing dementia, cerebellar and extrapyramidal symptoms, and rather specific MRI, EEG, and CSF findings. Clinically, the diagnosis is described as possible or probable prion disease and needs to be confirmed by neuropathological or immunological investigation of the brain tissue. Epidemiological data from the Czech Republic spanning the last decade are presented.

  5. Application of Subspace Detection to the 6 November 2011 M5.6 Prague, Oklahoma Aftershock Sequence

    Subspace detection is a powerful tool for the identification of small seismic events. Subspace detectors improve upon single-event matched filtering techniques by using multiple orthogonal waveform templates whose linear combinations characterize a range of observed signals from previously identified earthquakes. Subspace detectors running on multiple stations can significantly increasing the number of locatable events, lowering the catalog's magnitude of completeness and thus providing extraordinary detail on the kinematics of the aftershock process. The 6 November 2011 M5.6 earthquake near Prague, Oklahoma is the largest earthquake instrumentally recorded in Oklahoma history and the largest earthquake resultant from deep wastewater injection. A M4.8 foreshock on 5 November 2011 and the M5.6 mainshock triggered tens of thousands of detectable aftershocks along a 20 km splay of the Wilzetta Fault Zone known as the Meeker-Prague fault. In response to this unprecedented earthquake, 21 temporary seismic stations were deployed surrounding the seismic activity. We utilized a catalog of 767 previously located aftershocks to construct subspace detectors for the 21 temporary and 10 closest permanent seismic stations. Subspace detection identified more than 500,000 new arrival-time observations, which associated into more than 20,000 locatable earthquakes. The associated earthquakes were relocated using the Bayesloc multiple-event locator, resulting in ~7,000 earthquakes with hypocentral uncertainties of less than 500 m. The relocated seismicity provides unique insight into the spatio-temporal evolution of the aftershock sequence along the Wilzetta Fault Zone and its associated structures. We find that the crystalline basement and overlying sedimentary Arbuckle formation accommodate the majority of aftershocks. While we observe aftershocks along the entire 20 km length of the Meeker-Prague fault, the vast majority of earthquakes were confined to a 9 km wide by 9 km deep

    + with 0.003 g.m-2.year-1, were negligible. If we summarized all nitrogen species considered, the dry deposition over most part of the CR was as high as 3.1 g.m-2.year-1, indicating six-fold higher deposition as compared to the value reported by Ostatnická (2009). Preliminary verification comparing measured and modeled wet deposition (particularly N/NO3- and N/NH4+) indicated that modeled values were two times lower for N/NO3-, and three times lower for N/NH4+ as compared to measured values. Substitution of unmeasured nitrogen species by modeled values seems to be a plausible way for approximation of total nitrogen deposition, and getting more realistic spatial pattern for further studies of likely nitrogen impacts on ecosystems.

    The history of traditional capuchin balsam is the focal point of the second part of the article on the unknown history of pharmacy at the capuchin monastery in Prague-Hradčany. Capuchin balsam, a medicinal speciality, was being manufactured in the monastery from the end of the 18th century till the year 1950. It is a spirit tincture, its prescription originating from the formulation by Oswald Croll. Balsamum Peruvianum, Gummiresina myrrha, Gummiresina olibanum, and Styrax are the main ingredients, besides assorted plants. The balsam was taken as an antiseptic, antiphlogistic, and analgesic. The balsam was a favoured rustic medicine, and it was sold also abroad (Germany, Poland, USA, Ireland, Belgium). The profit made from the sale of the balsam supported the reconstruction and the maintenance of the monastery and the local theological studies. Other medical formulations connected with the name of the capuchin order are also mentioned.Key words: pharmaceutical history capuchins capuchin balsam monastics pharmacies.

    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.

    Many fire risk models have been developed for various temporal and spatial scales and application purposes. The integrated warning service in the Czech Republic is used for wildfire risk assessment model of FDI (Fire Danger Index). 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. Simply say higher index value, reflects to higher risk of wildfire. As input data, the model uses measured values from the Czech Hydrometeorological Institute stations network as well as ALADIN's model predicted conditions. The modelling process computes upper soil profile moisture, surface moistening and the spreading speed of fire. Early warning system for wildfires prevention in the Czech Republic is used since 2006.

  11. Verification of the radiometric map of the Czech Republic.

    The radiometric map of the Czech Republic is based on uniform regional airborne radiometric total count measurements (1957-1959) which covered 100% of the country. The airborne radiometric instrument was calibrated to a (226)Ra point source. The calibration facility for field gamma-ray spectrometers, established in the Czech Republic in 1975, significantly contributed to the subsequent radiometric data standardization. In the 1990's, the original analogue airborne radiometric data were digitized and using the method of back-calibration (IAEA, 2003) converted to dose rate. The map of terrestrial gamma radiation expressed in dose rate (nGy/h) was published on the scale 1:500,000 in 1995. Terrestrial radiation in the Czech Republic, formed by magmatic, sedimentary and metamorphic rocks of Proterozoic to Quaternary age, ranges mostly from 6 to 245 nGy/h, with a mean of 65.6 ± 19.0 nGy/h. The elevated terrestrial radiation in the Czech Republic, in comparison to the global dose rate average of 54 nGy/h, reflects an enhanced content of natural radioactive elements in the rocks. The 1995 published radiometric map of the Czech Republic was successively studied and verified by additional ground gamma-ray spectrometric measurements and by comparison to radiometric maps of Germany, Poland and Slovakia in border zones. A ground dose rate intercomparison measurement under participation of foreign and domestic professional institutions revealed mutual dose rate deviations about 20 nGy/h and more due to differing technical parameters of applied radiometric instruments. Studies and verification of the radiometric map of the Czech Republic illustrate the magnitude of current deviations in dose rate data. This gained experience can assist in harmonization of dose rate data on the European scale.

    We have estimated the number of serious fungal infections in the Czech Republic. All published epidemiology papers reporting Czech fungal infection rates were identified. Where no data existed, we used specific populations at risk and fungal infection frequencies in those populations. Population statistics were obtained from the 2011 Census data, prevalence and incidence data for at-risk conditions were obtained from publicly accessible healthcare statistics and relevant surveys. We estimate that 152,840 Czech women suffer with recurrent vaginal thrush. Allergic bronchopulmonary aspergillosis is likely in 4739 adults and 6581 more have severe asthma with fungal sensitisation. Hypersensitivity pneumonitits secondary to fungi is estimated in 1050 cases and 365 people may have chronic pulmonary aspergillosis. Oesophageal candidiasis is estimated in 210 HIV-positive people. There are 12 cases of Pneumocystis pneumonia in HIV population and 60 more cases in non-HIV population. There are an estimated 526 cases of candidaemia, 79 cases of Candida peritonitis and 297 cases of invasive aspergillosis a year. About 176,000 (1.67%) Czech people suffer from severe fungal infections each year, predominantly from recurrent vaginitis and allergic respiratory conditions. Substantial uncertainty surrounds these estimates except for invasive aspergillosis in haematology and candidaemia in critical care.

    2014-08-01

    Nuclear medicine in the Czech Republic is a full specialty with an exclusive practice. Since the training program was organized and structured in recent years, residents have had access to the specialty of nuclear medicine, starting with a two-year general internship (in internal medicine or radiology). At present, nuclear medicine services are provided in 45 departments. In total, 119 nuclear medicine specialists are currently registered. In order to obtain the title of Nuclear Medicine Specialist, five years of training are necessary; the first two years consist of a general internship in internal medicine or radiology. The remaining three years consist of training in the nuclear medicine specialty itself, but includes three months of practice in radiology. Twenty-one physicians are currently in nuclear medicine training and a mean of three specialists pass the final exam per year. The syllabus is very similar to that of the European Union of Medical Specialists (UEMS), namely concerning the minimum recommended numbers for diagnostic and therapeutic procedures. In principle, the Czech law requires continuous medical education for all practicing doctors. The Czech Medical Chamber has provided a continuing medical education (CME) system. Other national CMEs are not accepted in Czech Republic.

  7. Low stress drops observed for M1.5-5.6 Earthquakes During the 2011 Prague, Oklahoma sequence

    2015-12-01

    In November 2011, three M≥4.8 earthquakes and thousands of aftershocks occurred along the structurally complex Wilzetta fault system near Prague, Oklahoma. Previous studies suggest that fluid injection in nearby wells was responsible for inducing the M4.8 foreshock [Keranen et al., 2013], which subsequently triggered the M5.6 mainshock [Sumy et al., 2014]. We examine earthquake source properties using waveforms collected by 47 temporary and permanent seismic stations installed within ~100 km of the events. Brune stress drops are calculated for a subset of 278 aftershocks of the Prague, Oklahoma sequence that range in magnitude from M1.0-4.9. We compute the horizontal amplitude spectra and smooth the spectra with a Konno and Ohmachi [1998] filter. We then assume a standard Brune source spectral model and iteratively solve for seismic moment (Mo), corner frequency (fc) and kappa (κ) using a Gauss-Newton method. We are able to recover reasonably fit Mo, fc, and κ for 172 earthquakes, but find the Mo determined by spectra fit are consistently overestimated for events with M<1.5. Therefore only stress drops for the 149 events with initial Mo > 1.5 are reported. The median stress drop is ~0.3 MPa (3 bars), which is significantly lower than typical values (10+ MPa) observed for CEUS events. We find minimal dependence of stress drop on focal depth for the depth range from 1-10 km. However, we observe some spatial variation of stress drops, with higher stress drops observed near the intersection of the mainshock rupture plane with the fault plane associated with the M4.8 aftershock. The low stress drops observed for events on both the foreshock and mainshock fault plane may indicate both of these segments of the Wilzetta fault system were influenced by local wastewater injection. Our results echo those of several recent studies [Hough, 2014; Sun and Hartzell, 2014], which conclude that induced earthquakes have lower stress drops than tectonic events.

  8. Ground Motion Attenuation and Shear-Wave Splitting Analyses for the November 2011 M5.7 Prague, Oklahoma Earthquake

    NASA Astrophysics Data System (ADS)

    Sumy, D. F.; Cochran, E. S.; Keranen, K. M.; Neighbors, C.; Atkinson, G. M.

    2014-12-01

    During November 2011, three M≥5.0 earthquakes and thousands of aftershocks occurred on and near the Wilzetta fault, a structurally complex ~200 km long, Pennsylvanian-aged fault near Prague, Oklahoma, in close proximity to several active wastewater injection wells. All three M≥5.0 earthquakes had strike-slip mechanisms consistent with rupture on three independent focal planes, suggesting activation of three different strands of the Wilzetta fault. Wastewater injection can cause a buildup of pore fluid pressure along the fault, which decreases the fault strength and may induce earthquakes. Based on the proximity of earthquakes to active fluid injection wells, the unilateral progression of aftershocks away from the initial M5.0 event, and shallow earthquake depths, Keranen et al. [2013] concluded that fluid injection was responsible for inducing the first M5.0 event. Furthermore, Sumy et al. [2014] found that the initial M5.0 event increased the Coulomb stress in the region of the M5.7 mainshock, triggering a cascade of earthquakes along the Wilzetta fault. Thus, while nearby wastewater injection directly induced the initial M5.0 event, this earthquake triggered successive failure along the Wilzetta fault; however, it remains unclear if the additional ruptured fault strands are also influenced by fluid injection. In this study, we explore instrumental ground motions and shear-wave splitting of the November 2011 Prague, Oklahoma sequence, in order to construct ground motion prediction equations (GMPEs) and understand the local stress regime, respectively. We examine ~1,000 earthquakes recorded by a total of 47 seismometers, located within ~150 km of the Wilzetta fault. With respect to GMPEs, initial results suggest that the ground motions are smaller than similar magnitude earthquakes of natural/tectonic origins, and these lower intensities may be a result of lower stress drops [e.g. Hough, 2014]. With respect to shear-wave splitting, we examine quality graded

    The aim of this study was to find any relation between soft facial tissue thickness (FSTT) and sex, age and asymmetry in the contemporary Czech population. The studied sample consisted of head CT scans of 102 adult Czech individuals between the ages of 21 and 83. Forty FSTTs were evaluated and analysed using PCA, Hotelling's T(2) test, LDA, the Kolmogorov-Smirnov test, MANOVA, the Kruskal-Wallis test and Wilcoxon's paired test. The greatest sexual dimorphism was detected in the lower part of the face, which had discriminant power almost the same as the entire faces (approximately 80%). On the other hand, a significant influence of aging was shown, mostly in the area of the upper face (In females, twice as many landmarks displayed a significant influence, compared with males). The influence of asymmetry was confirmed in seven bilateral landmarks, five of them favouring the right side.

    Managing inventory is considered as one of the most challenging tasks facing supply chain managers and specialists. Decisions related to inventory locations along with level of inventory kept throughout the supply chain have a fundamental impact on the response time, service level, delivery lead-time and the total cost of the supply chain. The main objective of this paper is to identify and analyse the share of a particular logistic model adopted in the Czech Republic (Consignment stock, Buffer stock, Safety stock) and also compare their usage and adoption according to different industries. This paper also aims to specify possible reasons of particular logistic model preferences in comparison to the others. The analysis is based on quantitative survey held in the Czech Republic.

    1998-01-01

    Polymorphism at the BoLA DYA locus was determined in two groups of Czech Black Pied cattle by PCR-RFLP detecting substitutions at nucleotide positions 112 and 219. Animals for this study were nonrandomly selected according to their health status in two BoLA-associated infections: bovine leukosis (n = 59) and Johne's disease (n = 36). A group of noninfected Czech Red Pied cows (n = 37) was used for comparison. The frequencies of DYA alleles and haplotypes were virtually identical in the two selected groups as well as in the infection-free animals. In contrast, distribution of BoLA DRB3.2 alleles differed considerably between the infected groups as expected based on the previously detected associations with BoLA. The results suggest that the polymorphism of the DYA unexpressed gene was not influenced by selecting animals for this study according to their health status.

    On 6 April 2011, the ESO Paranal Observatory was honoured with a visit from the President of the Czech Republic, Václav Klaus, and his wife Livia Klausová, who also took the opportunity to admire Cerro Armazones, the future site of the planned E-ELT. The distinguished visitor was shown the technical installations at the observatory, and was present when the dome of one of the four 8.2-metre Unit Telescopes of ESO's Very Large Telescope opened for a night's observing at Cerro Paranal, the world's most advanced visible-light observatory. "I'm delighted to welcome President Klaus to the Paranal Observatory and to show him first-hand the world-leading astronomical facility that ESO has designed, has built, and operates for European astronomy," said ESO's Director General, Tim de Zeeuw. President Klaus replied, "I am very impressed by the remarkable technology that ESO has built here in the heart of the desert. Czech astronomers are already making good use of these facilities and we look forward to having Czech industry and its scientific community contribute to the future E-ELT." From the VLT platform, the President had the opportunity to admire Cerro Armazones as well as other spectacular views of Chile's Atacama Desert surrounding Paranal. Adjacent to Cerro Paranal, Armazones has been chosen as the site for the future E-ELT (see eso1018). ESO is seeking approval from its governing bodies by the end of 2011 for the go-ahead for the 1-billion euro E-ELT. Construction is expected to begin in 2012 and the start of operations is planned for early in the next decade. President Klaus was accompanied by the Minister of Foreign Affairs of the Czech Republic, Karel Schwarzenberg, the Czech Ambassador in Chile, Zdenek Kubánek, dignitaries of the government, and a Czech industrial delegation. The group was hosted at Paranal by the ESO Director General, Tim de Zeeuw, the ESO Representative in Chile, Massimo Tarenghi, the Director of Operations, Andreas Kaufer, and Jan Palous

    1994-08-01

    Energy efficiency is a particularly important issue in the emerging economies of Eastern Europe. Much of the energy used in the Czech Republic is supplied by lignite, a soft brown form of coal. Its combustion is largely responsible for an extreme acid rain problem and other forms of air pollution and land use complications. Additionally, inefficient energy use is prevalent, placing additional stresses on an already fragile economy. This paper reports on a project in the mid-sized (250,000 residents) and industrial city of Plzen, in the Czech Republic. The Facility Energy Decision Screening (FEDS) process, developed by PNL for the U.S. Department of Energy`s (DOE`s) Federal Energy Management Program (FEMP), was applied to the city to determine the level of cost-effective energy efficiency potential in the city. Significant potential was found to exist, primarily in large, cooperatively owned apartment buildings heated by district systems.

    The Czech Republic has signed the Association Agreement with the European Union in early nineties and it has been the Republic's goal to accede to full membership in the European Union. In the power sector, the Directive 96/92/EC is, in this respect, the most important document. The Czech Energy Law was become effective from 1995 in a compromise form which proved to stay well short of perfection. Unfortunately, a number of articles and provisions fail to be consistent with the relevant EU documents, and even far less so with Directive 96/92/EC. The draft Energy Policy of the Czech Republic as presented officially in May 1997, has already definitely stressed some basic features of the future market in electricity. Regrettably, also in the draft Energy Policy some pressing long-term problems fail to be recognized or addressed and also areas failing to conform with the European power industry laws can be found in it. For the Czech Republic, it will be useful to utilize the experience of mainly the smaller EU countries and to proceed in pursuance of the findings of a thorough analysis and in a stepwise manner. In the first phase, it will be enough to make those moves which are common for all the conceivable solutions. Directive 96/92/EC does not prescribe a change in the structure of the existing electric power sector and far less any change in the ownership relation. In the same token, Directive 96/92/EC does not charge the member states with any duty to launch a wholesale market in electricity (pool of exchange). That is reserved under the discretion of the member states. Nowhere throughout the Directive is encountered any requirement to reduce the market strength of the dominant entities, if such exist.

    Rubber dam is considered an ideal device for tooth isolation. Nevertheless, its usage is quite rare in the Czech Republic. The aim of this study was: firstly, to gather and evaluate information regarding the use of rubber dam by dentists in the Czech Republic and to compare it with other countries; secondly to find out whether there are any influencing factors as to rubber dam usage; and finally to find out frequency of rubber dam use separately in endodontic treatment and in placing fillings of different materials. A questionnaire-based survey was conducted. Dentists filled in the questionnaires during dental conventions, educational events, conferences and congresses. Rubber dam was routinely used by less than eight per cent of the respondents (n = 35); less than twenty-two per cent of the respondents (n = 97) used rubber dam occasionally, and more than seventy per cent of the respondents (n = 317) has never use it. The results showed that rubber dam is not used frequently in the Czech Republic. If rubber dam is used, then it is typically for endodontic treatment or composite fillings. There were several factors with a statistically significant influence on the usage of rubber dam, such as gender, length of professional career, percentage of direct payments, previous experience in using rubber dam, and undergraduate training in rubber dam use.

  18. Eu accession and its consequences for Czech professionals.

    2004-01-01

    In March 2003, the Erasmus University Rotterdam (The Netherlands) organised a conference on EU accession and its consequences for applicant countries' health systems. One of the sessions dealt with health professionals. Questions raised during this meeting concerned the impact of accession on medical doctors, in particularly the options of new member state nationals to practice their profession in another member state, and the reverse. It appeared that there are several (legal) barriers for border crossing professionals. This issue is of extreme importance to both the EU, its member states and the applicant countries. Therefore, it is of importance that Czech health professionals participate in this debate. Due to many uncertainties in the pre-accession stage, the conference could not give a clear answer to all the questions. This contribution is an attempt to enhance the national debate on potential consequences of the free movement of persons to the Czech Republic by explaining the European legal context of free movement of persons and to make some critical remarks on the Czech situation.

    2013-10-01

    This article is concerned with identifying economic factors primarily that affect birth rates in Czech Republic. To find the relationship between the magnitudes, we used the multivariate regression analysis and for modeling, we used a time series of annual values (1994-2011) both economic indicators and indicators related to demographics. Due to potential problems with apparent dependence we first cleansed all series obtained from the Czech Statistical Office using first differences. It is clear from the final model that meets all assumptions that there is a positive correlation between birth rates and the financial situation of households. We described the financial situation of households by GDP per capita, gross wages and consumer price index. As expected a positive correlation was proved for GDP per capita and gross wages and negative dependence was proved for the consumer price index. In addition to these economic variables in the model there were used also demographic characteristics of the workforce and the number of employed people. It can be stated that if the Czech Republic wants to support an increase in the birth rate, it is necessary to consider the financial support for households with small children.

  20. Insights from the 2011 Prague, Oklahoma earthquake sequence on the role of damage zones in the seismic cycle

    2013-12-01

    Although most faults are surrounded by a halo of fractured rock known as a damage zone, it is not clear what role damage zones play during the seismic cycle on mature faults. Here, we present a superbly-located foreshock-mainshock-aftershock sequence that demonstrates most aftershocks are located within the damage zone surrounding the fault. The 2011 Prague, Oklahoma sequence included three M5+ earthquakes along three different faults over a three-day period. The third event was captured with an array of nine seismometers with ~2 km spacing, allowing for precise event location. We located more than 1000 foreshocks and aftershocks of the November 8 M5 event within a 14 hour time window, and relocated these aftershocks using singular-value decomposition in HypoDD. Because of the accuracy in event horizontal location, we can use these events to compare aftershock distribution to fracture distributions within damage zones surrounding faults. The aftershock sequence localizes to a damage zone thickness that scales with the length of the rupture patch, similar to previously documented scaling between fault length and damage zone thickness. Furthermore, the falloff in aftershock density decays precipitously away from the fault, in a similar fashion to fracture density decay in damage zones. Most aftershocks in this sequence occur within the first hour after the mainshock, and there is no obvious migration of aftershocks away from the fault with time. Finally, foreshock activity along this fault was limited to the intersection with the fault that had hosted a M5.7 earthquake two days prior.

    The presented study is focused on the analysis and comparison of hydrological drought occurrence, development and duration in six small to middle sized catchments in the Czech Republic (CZ) and Slovakia. The main questions to be answered are: (1) are there correlations between the physical conditions in the catchments and drought occurrence, and (2) does the spatial trend of drought occurrence exist. The Žitava catchment is located in the central western part of Slovakia having runoff dominated by rainfall with the contribution of snow melting during the spring period. The Belá River catchment is located on the contact of Západné and Vysoké Tatry Mts. in the north of Slovakia. The runoff is snow to snow-rain combined type. The Ľupčianka catchment is located on the northern slopes of the Nízke Tatry Mts. in the northern part of the central Slovakia. The runoff regime is snow-rain combined in the upper part of the catchment, and of rain-snow type in the rest of catchment. The Rakovnický potok brook (CZ) has its spring in Rakovnická pahorkatina hilly land. Runoff is dominated by rainfall, quite heavily influenced by water uptakes in the catchment. The Teplá River (CZ) originates in peat meadows in the western part of the Czech Republic. Runoff is dominated by rainfall. The Metuje catchment (CZ) is formed by Adršsbach-Teplické stěny Upland. The headwater part is typical by deeply incest valleys, table mountains and pseudokarst caves. The discharge is fed dominantly by groundwater. The streamflow drought was characterized using discharge data, the groundwater drought using the base flow values. The local minimum method was used for base flow separation. The threshold level method (Q80, BF80) and the sequent peak algorithm were used for calculation of drought duration in discharge and base flow time series. The data of the same three decades of the common period (1971 - 1980, 1981 - 1990 and 1991 - 2000) were used. The resulting base flow values along with

    In the field of civil engineering applications in the Czech Republic, Ground Penetrating Radar (GPR) is used particularly for the diagnostics of roads and bridges. There is no producer of GPR in the Czech Republic, sets of different producers are used, particularly Geophysical Survey Systems, Inc. (USA) and MALÅ GeoScience (Sweden). The measurement results are mostly processed by software Radan, Road Doctor Pro, ReflexW and RadEx. The only technical specification in the Czech Republic is TP 233 issued by the Ministry of Transport, which describes the diagnostics of roads by GPR. Apart from a basic description of the method and a measurement system, it mentions possible applications. The only application where accuracy is mentioned is the locating of dowels and tie bars in concrete road pavements, which states that if calibration is performed, the expected depth accuracy is up to 1.0 cm. The following R&D project is currently in progress: New diagnostics methods as a supporting decision tool for maintenance and repair of road pavements - their contribution and ways of their usage (2012-2014) The project aims to test possible non-destructive methods (particularly GPR and laser scanning), make recommendations when and how to use specific methods for individual applications and for changes in technical specifications. The following R&D projects have been recently completed: Position of dowels and tie bars in rigid pavements and importance of their correct placement to pavement performance and service life (2012-2013) The project included an analysis of individual NDT methods used for the location of dowels and tie bars and for testing of their accuracy - GPR, MIT-scan and GPR in combination with a metal detector. Multichannel ground penetrating radar as a tool for monitoring of road and bridge structures (2009-2011) The project included detection of hollow spaces under non-reinforced concrete pavements, detection of excessive amount of water in road construction

    The first specialist nursing team placing peripherally inserted central catheters (PICCs) in the Czech Republic was established in September 2012. During 2013 the team placed 167 PICCs and 162 midline catheters. In another 6 patients the insertion was not successful. PICCs were inserted mainly for oncology patients; while midline catheters were inserted for patients admitted to general wards. Average duration of catheter insertion was 91 days (range 7-285 days) for PICCs and 14 days (range 2-40 days) for midline catheters. During follow up of PICCs, catheter infection rate was 0.3/1000 days, vein thrombosis rate 0.4/1000 days, catheter occlusion 0.4/1000 days, and catheter displacement 0.33/1000 days. For midline catheters infection rate was 1.4/1000 days, vein thrombosis 5.2/1000 days, catheter occlusion 2.6/1000 days, and catheter displacement 2.2/1000 days. The authors hope that these results will motivate other hospitals in the Czech republic to establish PICC teams, as in other European countries.

    The aim of presented review is to address the most relevant issues related to the health effects caused by the human exposure to lead, as they have been recognized in Czech Republic in the period of 1992-1994 within the framework of the National Integrated Programme on Environment and Health (NIPEH) approved in 1992 and supported by WHO-European Centre for Environment and Health (WHO-ECEH), Bilthoven, The Netherlands and by the Government of the Netherlands. Basic sources of environment exposure to lead are identified and the fate of lead in the individual compartments of the environment is discussed. Relevant methods used for the exposure evaluation are summarized and the highest-risk group of population is defined. Attention is being paid to the effects of the long-term exposure to low lead levels, while other exposure settings are intentionally omitted. Interventional measures developed in the Czech Republic in attempt to reduce the environmental exposure are introduced. Instead of presenting specific data, current state-of-art and general trends are presented; list of references tries to combine the internationally recognized studies with those coming from national sources.

  20. Climate forcings of past droughts in the Czech Lands

    NASA Astrophysics Data System (ADS)

    2015-04-01

    Frequency and intensity of local droughts is governed by a complex interaction of diverse processes, originating from internal dynamics of the climate system as well as its responses to external forcings. Separating and quantifying the effects of individual drought-inducing agents is a nontrivial task, often approached via statistical methods. In this presentation, we employ multiple linear regression to identify components attributable to various forcing factors, both external (solar irradiance, volcanic activity, anthropogenic greenhouse gases and aerosols) and internal (NAO, ENSO, AMO), in the monthly series of selected drought indices (PDSI, Z-index, SPI, SPEI) calculated for the territory of the recent Czech Republic during the 1883-2010 period. Moving block bootstrap is used for evaluation of the statistical significance of the results. Our analysis, carried out for drought index series characterizing a country-wide average as well as ten individual locations, suggests presence of a distinct component correlated with anthropogenic forcing (driven largely by the increasing concentrations of greenhouse gases) in the temperature-sensitive drought indices (PDSI, Z-index, SPEI). There are also indications of an influence of major volcanic eruptions in some of the Czech drought series, whereas variations of solar activity do not seem to leave a significant imprint. Of the major oscillatory modes in the climate system, North Atlantic Oscillation can be linked to a relatively strong component in most of the drought characteristics. Effects of ENSO, while generally weaker and scattered, are also detectable. No significant relation to Atlantic Multidecadal Oscillation phase was found.

  1. Upgrading selected Czech coals for home and industrial heating

    1995-12-31

    The Czech Republic has large coal reserves, particularly brown coal and lignite, and to a lesser extent, bituminous coal. Concurrent with the recent political changes, there has been a reassessment of the role of coal for electrical and heating energy in the future economy, owing to the large dependence on brown coal and lignite and the implementation of more stringent environmental regulations. These coals have a relatively high sulfur content, typically 1-3 wt%, and ash content, leading to significant SO{sub 2} and other gaseous and particulate emissions. Some of the bituminous coals also exhibit high ash content. Against this background, the Energy & Environmental Research Center, on behalf of the U.S. Agency for International Development and the U.S. Department of Energy Office of Fossil Energy, undertook a project on upgrading Czech coals to achieve desired fuel properties. The purpose of the project was to assist the city of Usti nad Labem in Northern Bohemia in developing cost-effective alternatives for reducing environmental emissions from district and home heating systems.

    2012-01-01

    Background Schistosoma reflexum (SR) is congenital syndrome briefly characterized by visceral eventration, severe dorsoflexion and ankylosis of the spine and arthrogryposis. A genetic etiology has been proposed, but conclusive evidence has not yet been provided. Methods Pedigree analysis was carried out in 29 cases of SR in Czech Holsteins and Holstein crosses. Genetic relationship was evaluated and inbreeding coefficients calculated. Pedigrees of 15 Czech Holsteins fathering non-SR affected calves were used for comparison. Results Twenty-one cases occurred in one pedigree founded by three sires while three SR calves occurred in another pedigree with a common grandfather. The sex ratio between affected males and females was 11:6. Affected calves shared common ancestors different from those shared by the unaffected calves. The inbreeding coefficient in the SR affected calves was not increased compared to unaffected calves. Conclusions The findings are consistent with SR being inherited autosomal recessively. Further studies are however needed to confirm this and therefore a breeding trial is recommended where a suspected heterozygous sire is mated to closely related females. PMID:22472123

    The fuel and energy base in Czech Republic is presently in a period of great structural change. The substantial problem is the evolution from a centrally planned system to a market economy model of extraction, production and consumption of fuel and energy sources. The biggest contemporary problems are the following: (1) very high energy consumption per GNP-unit as a consequence of the recent period of cheap energy subsidized by the government; (2) not existing programs for energy savings, regeneration, and renewable sources; (3) up until now, low energy price and its distortion by targeted subsidies don`t allow us to estimate the alternative energy sources economically; (4) due to crude oil and gas import in the economy almost wholly dependent on unreliable sources in the former Soviet Union; (5) as a consequence of an oversized energy consumption there are relevant environment problems; and, (6) the current economic situation in the industry doesn`t enable it to provide sufficient investment capital targeted to energy savings or utilization of renewable sources. In the area of solid fuels management, the Czech economy will have to face unknown competitive forces on the free coal market, where increasingly Canadian, Australian, American and South Afrikan coals are pushed through. A specific problem appears to be the competition of some European coals that have a high rate of state subventions. Total geological coal reserves in former Czechoslovakia amount to 28 billion tons.

  5. Beginnings of rocket development in the czech lands (Czechoslovakia)

    NASA Astrophysics Data System (ADS)

    Plavec, Michal

    2011-11-01

    Although the first references are from the 15th Century when both Hussites and crusaders are said to have used rockets during the Hussite Wars (also known as the Bohemian Wars) there is no strong evidence that rockets were actually used at that time. It is worth noting that Konrad Kyeser, who described several rockets in his Bellifortis manuscript written 1402-1405, served as advisor to Bohemian King Wenceslas IV. Rockets were in fact used as fireworks from the 16th century in noble circles. Some of these were built by Vavřinec Křička z Bitý\\vsky, who also published a book on fireworks, in which he described how to build rockets for firework displays. Czech soldiers were also involved in the creation of a rocket regiment in the Austrian (Austro-Hungarian) army in the first half of the 19th century. The pioneering era of modern rocket development began in the Czech lands during the 1920s. The first rockets were succesfully launched by Ludvík Očenášek in 1930 with one of them possibly reaching an altitude of 2000 metres. Vladimír Mandl, lawyer and author of the first book on the subject of space law, patented his project for a stage rocket (vysokostoupající raketa) in 1932, but this project never came to fruition. There were several factories during the so-called Protectorate of Bohemia and Moravia in 1939-1945, when the Czech lands were occupied by Nazi Germany, where parts for German Mark A-4/V-2 rockets were produced, but none of the Czech technicians or constructors were able to build an entire rocket. The main goal of the Czech aircraft industry after WW2 was to revive the stagnant aircraft industry. There was no place to create a rocket industry. Concerns about a rocket industry appeared at the end of the 1950s.

    The photovoltaic (PV) power system for Space Station Freedom (SSF) uses solar array blankets which provide structural support for the solar cells and house the electrical interconnections. In the low Earth orbital (LEO) environment where SSF will be located, surfaces will be exposed to potentially damaging environmental conditions including solar ultraviolet (UV) radiation, thermal cycling, and atomic oxygen. It is necessary to use ground based tests to determine how these environmental conditions would affect the mass loss and optical properties of candidate SSF blanket materials. Silicone containing, silicone coated, and SiO(x) coated polyimide film materials were exposed to simulated LEO environmental conditions to determine there durability and whether the environmental conditions of UV, thermal cycling and oxygen atoms act synergistically on these materials. A candidate PV blanket material called AOR Kapton, a polysiloxane polyimide cast from a solution mixture, shows an improvement in durability to oxygen atoms erosion after exposure to UV radiation or thermal cycling combined with UV radiation. This may indicate that the environmental conditions react synergistically with this material, and the damage predicted by exposure to atomic oxygen alone is more severe than that which would occur in LEO where atomic oxygen, thermal cycling and UV radiation are present together.

    The Tsunami disaster affected several countries in Southeast Asia in December 2004 and killed or affected many tourists, most of them from Europe. Eight Czech citizens died, and about 500 Czechs were seriously mentally traumatized. The psychosocial needs of tourists included: (1) protection; (2) treatment; (3) safety; (4) relief; (5) psychological first aid; (6) connecting with family members; (7) transportation home; (8) information about possible mental reactions to trauma; (9) information about the normality of their reaction; (10) procedural and environmental orientation; (11) reinforcement of personal competencies; and (12) psycho-trauma therapy. The Ministry of Foreign Affairs of the Czech Republic was in charge of general emergency management. General coordination of psychosocial support was coordinated under the Ministry of Interior of the Czech Republic, which is connected to the Central Crisis Staff of the Czech Government. The major cooperative partners were: the Ministry of Foreign Affairs, the Ministry of Defence, the Ministry of Health, Czech Airlines, psychosocial intervention teams of the Czech Republic, and the Czech Association of Clinical Psychologists. The main goals of relief workers were: (1) to bring back home the maximum number of Czech citizens; (2) to provide relevant information to the maximum number of affected Czech citizens; (3) to provide relevant information to rescue workers and professionals; and (4) to prepare working psychosocial support regional network. Major activities of the Ministry of Interior (psychology section) included: (1) establishing a psychological helpline; (2) running a team of psychological assistance (assistance in the Czech airports, psychological monitoring of tourists, crisis intervention, psychological first aid, assistance in the collection of DNA material from relatives); (3) drafting and distributing specific information materials (brochures, leaflets, address lists, printed and electronic instructions

    Pornography continues to be a contentious matter with those on the one side arguing it detrimental to society while others argue it is pleasurable to many and a feature of free speech. The advent of the Internet with the ready availability of sexually explicit materials thereon particularly has seemed to raise questions of its influence. Following the effects of a new law in the Czech Republic that allowed pornography to a society previously having forbidden it allowed us to monitor the change in sex related crime that followed the change. As found in all other countries in which the phenomenon has been studied, rape and other sex crimes did not increase. Of particular note is that this country, like Denmark and Japan, had a prolonged interval during which possession of child pornography was not illegal and, like those other countries, showed a significant decrease in the incidence of child sex abuse.

    The present study provides normative data stratified by age for the Rey Auditory Verbal Learning test Czech version (RAVLT) derived from a sample of 306 cognitively normal subjects (20-85 years). Participants met strict inclusion criteria (absence of any active or past neurological or psychiatric disorder) and performed within normal limits on other neuropsychological measures. Our analyses revealed significant relationships between most RAVLT indices and age and education. Normative data are provided not only for basic RAVLT scores, but for the first time also for a variety of derived (gained/lost access, primacy/recency effect) and error scores. The study confirmed a logarithmic character of the learning slope and is consistent with other studies. It enables the clinician to evaluate more precisely subject's RAVLT memory performance on a vast number of indices and can be viewed as a concrete example of Quantified Process Approach to neuropsychological assessment.

    The aim of the present study was to investigate the relationship between domains of the job satisfaction and components of subjective well-being in nurses. A convenience sample of hospital nurses was recruited from six hospitals in Czech Republic. Data were collected using a set of questionnaires that included the McCloskey/Mueller Satisfaction Scale, the Positive Affect Scale, the Negative Affect Scale and the Personal Well-being Index. We confirmed low association between job satisfaction and subjective well-being of nurses. Satisfaction with extrinsic rewards, co-workers and family/work balance accounted for only a small percentage of variance in cognitive component of subjective well-being. Positive affect was predicted by interaction opportunities and scheduling. Negative affect was predicted by interaction opportunities and scheduling and intention to leave the actual workplace. Low percentage of the variance suggests that subjective well-being is not strongly influenced by job satisfaction.

  12. The lack of isolated palatal clefts in Czech Gypsies.

    Orofacial clefts are usually divided into three basic types: isolated cleft lip (CL), cleft lip and palate (CLP) and isolated cleft palate (CP). The incidence of specific cleft types in a population and their relative numbers show specific differences between ethnic groups and races. However, there are no available data about the incidence and relative numbers of orofacial cleft types (CL, CLP, CP) in the gypsy ethnic group. The aim of this study was to compare relative numbers of specific types of orofacial clefts between the Czech gypsy and non-gypsy populations. We conducted a retrospective epidemiological study using a set of all living patients with orofacial clefts born in the Czech Republic from 1964 until 2002. The cleft patients were subdivided into three groups: 5304 non-gypsy children, both parents of whom were non-gypsies (NN), 98 gypsy children, both parents of whom were gypsies (GG) and 18 children with one parent non-gypsy and one parent gypsy (NG). The relative number of isolated CP was 37.1% in NN children. However, the relative number of CP was significantly reduced to 5.1% (P < 0.01) in the GG group. Conversely, the relative number of CLP was higher (P < 0.01) in the GG group (62.2%) in comparison to the NN group (39.2%). The tendency to decrease in the relative number of CP and increase in the relative number of CLP was also apparent in the NG group, but not so well expressed. We hypothesize that the decrease in CP and increase in CLP and CL in gypsies might be caused by their genetic predis-position to CL. Since the CP originates later than CL during embryonic development, some CP arise in embryos with already existing CL giving rise to CLP. Consequently, the missing isolated CP might be hidden in the group of CLP patients postnatally.

    2009-04-01

    Since 2002, we found relatively stable number of diabetes mellitus cases among clients of General Health Insurance Company of the Czech Republic. This means, after calculating incidence rate with respect to decline in total numbers of insured during the same period, a 6% increase in real incidence rate. On the doctors side, outpatient, mostly private diabetologists have about the same capacity of their offices, 2.9 physicians (WTE)/100 000 citizens over the last years. Analysis of costs and volume of services provided, clearly demonstrate, that diabetology is medical specialization of a great importance not only from the point of view of number of patients and services provided but also of its influence on the overall health care costs. Data show not only higher average expenses for treatment of patients with diabetes mellitus compared to average expenses incurred for treatments of all other diagnoses, but show also a crucial relationship of costs with presence or absence of diabetes mellitus complications. Money spend by the medical insurance system and also and more importantly health profit to patients can thus be substantially influenced via improvements in organization of care, via higher involvement, compliance of patients to the treatment and to necessary change in their lifestyles and last but not least via increase in quality of care. Cost control can be achieved by strengthening the role of pharmacoeconomics in decisions making processes of health insurance companies, importance of which is demonstrated on the past developments on drug market in the Czech Republic. General Health Insurance Company will target these goals in coming years and in its business plans will also include expected increases of costs for organization of care and for higher renumeration of physicians as well.

    During the Eighth International Conference on High Levels of Natural Radiation and Radon Areas held in autumn 2014 at Prague, the third intercomparison of radon/thoron gas and radon short-lived decay products measurement instruments was organised by and held at the Natural Radiation Division of the National Radiation Protection Institute (NRPI; SÚRO v.v.i.) in Prague. The intercomparison was newly focussed also on continuous monitors with active sampling adapters capable to distinguish radon/thoron gas in their mix field.The results of radon gas measurements carried out in the big NRPI radon chamber indicated very well an average deviation of up to 5 % from the reference NRPI value for 80 % of all the exposed instruments. The results of equilibrium equivalent concentration continuous monitors indicated an average deviation of up to 5 % from the reference NRPI value for 40 % of all the exposed instruments and their ~8-10 % shift compared with the NRPI. The results of investigated ambient conditions upon response of exposed continuous monitors indicated influence of aerosol changes upon response of radon monitors with an active air sampling adapters through the filter, only. The exposures of both radon/thoron gas discriminative continuous monitors and passive detectors have been indicated inconsistent results: on one hand, their excellent agreement up to several per cent for both the gases, and on the other hand, systematic unsatisfactory differences up to 40 %. Additional radon/thoron exercises are recommended to improve both the instruments themselves and quality of their operators.

    Although most faults are surrounded by a halo of fractured rock known as a damage zone, it is not clear what role damage zones play during the seismic cycle on mature faults. Here, we present a superbly-located foreshock-mainshock-aftershock sequence surrounding the November 8, M5 Prague Oklahoma earthquake, which demonstrates most aftershocks are located within the damage zone surrounding the fault. The 2011 Prague, Oklahoma sequence included three M5+ earthquakes along three different faults over a three-day period. The November 8th event was third in the sequence and captured with an array of nine seismometers with ~2 km spacing, allowing for precise event location. We located more than 1000 foreshocks and aftershocks within a 14 hour time window, and relocated these aftershocks using waveform cross correlation and HypoDD. Because of the location precision, we can use these events to investigate spatial and temporal complexity of the foreshock and aftershock sequences. First, we compare the aftershock distribution to fracture distributions within damage zones surrounding faults. The aftershock sequence localizes to a reasonable damage zone thickness given the rupture length of the event, according to previously documented scaling between fault length and damage zone thickness. Furthermore, the aftershock density is constant within the fault zone, but falls off precipitously outside of the damage zone. Most aftershocks in this sequence occur within the first hour after the mainshock, and there is some indication of temporal migration of aftershocks away from the fault. Finally, foreshock activity along this fault was limited to the intersection with the fault that had hosted a M5.7 earthquake two days prior. Because this earthquake is potentially linked to fluid waste disposal, we interpret our results in terms of hydraulic pressure changes during the foreshock-mainshock-aftershock sequence.

    CzechGeo/EPOS is a distributed network of geoscience observations operated by the Czech research institutions and universities. The system consists of permanent observatories usually incorporated in global data networks, local stations or networks in areas significant in the long-term for basic research or applications and mobile stations which serve for repeated observations at selected points, or for field measurements, usually within the scope of large international projects. CzechGeo/EPOS is closely connected with the large European research infrastructure EPOS (European Plate Observing System) and its service covers continuous monitoring of geophysical fields on Czech territory and in selected areas abroad via long uninterrupted series of measurements on fixed sites, which are vital for understanding of Earth interior processes. The infrastructure is organized in 5 sections: Seismology, GNSS and Gravimetry, Geodynamics, Geomagnetism, Geological and Geophysical Databases. CzechGeo/EPOS provides user-friendly data access to global or regional data bases/repositories, including real-time data access whenever possible, transmits access to high-level products (e.g. waveform data, seismological bulletins and regional catalogues, geomagnetic indices) and integrates data in the frame of the Implementation Phase of the EPOS Project. CzechGeo/EPOS involves nearly all observational activities related to the solid Earth carried out by the Czech geoscience institutions and thus is indispensable for any geoscience research on our territory. Through participation in more than twenty global or regional networks CzechGeo/EPOS builds up close cooperation with European partners and contributes substantially to better understanding of the processes in the Earth's interior.

    The US has invested heavily in research, development, and demonstration of efficient and environmentally acceptable technologies for the use of coal. The US has the opportunity to use its leadership position to market a range of advanced coal-based technologies internationally. For example, coal mining output in the Czech Republic has been decreasing. This decrease in demand can be attributed mainly to the changing structure of the Czech economy and to environmental constraints. The continued production of energy from indigenous brown coals is a major concern for the Czech Republic. The strong desire to continue to use this resource is a challenge. The Energy and Environmental Research Center undertook two major efforts recently. One effort involved an assessment of opportunities for commercialization of US coal technologies in the Czech Republic. This report is the result of that effort. The technology assessment focused on the utilization of Czech brown coals. These coals are high in ash and sulfur, and the information presented in this report focuses on the utilization of these brown coals in an economically and environmentally friendly manner. Sections 3--5 present options for utilizing the as-mined coal, while Sections 6 and 7 present options for upgrading and generating alternative uses for the lignite. Contents include Czech Republic national energy perspectives; powering; emissions control; advanced power generation systems; assessment of lignite-upgrading technologies; and alternative markets for lignite.

    We analyze droughts in the Czech Republic from 1881-2006 based on the Palmer drought severity index (PDSI) and the Z-index using averaged national temperature and precipitation series for the calculations. The standardized precipitation index (SPI), PDSI and Z-index series show an increasing tendency towards longer and more intensive dry episodes in which, for example, droughts that occurred in the mid-1930s, late 1940s-early 1950s, late 1980s-early 1990s and early 2000s were the most severe. Cycles at periods of 3.4-3.5, 4.2-4.3, 5.0-5.1 and 15.4 years exceeded 95% confidence levels in application of maximum entropy spectral analysis. These are expressed at different intensities throughout the period studied. The occurrence of extremely dry and severely dry months is associated with a higher frequency of anticyclonic situations according to the classification employed by the Czech Hydrometeorological Institute. Principal component analysis documents the importance of the ridge from the Siberian High over Central Europe when extreme and severe droughts in months of the winter half-year are considered in terms of sea-level pressure. In the summer half-year, the ridge of the Azores High over Central Europe is the most important. Drought episodes have a profound effect on national and regional agricultural production, with yields being consistently lower than in normal years, as is documented through the example of spring barley, winter wheat, forage crops on arable land, and hay from meadows. Seasons with pronounced drought during the April-June period (e.g., 1947 and 2000) show the most significant yield decreases. Forests appear to be very vulnerable to long-term drought episodes, as it was the case during the dry years of 1992-1994. This study clearly confirms the statistically significant tendency to more intensive dry episodes in the region, driven by temperature increase and precipitation decrease, which has already been suggested in other studies.

    The paper summarizes results of monitoring of (137)Cs activities in game species roaming in the woods over the territory of the Czech Republic for the time interval of 1986-2012. Geometric means and other statistical characteristics were estimated from the data sets on the assumption of log-normal distribution of the data from the time interval 2004-2012 where the character of data distribution had displayed no significant change. Geometric means (in Bq/kg) in meat were: wild boar 5.1, red deer 1.9, roe deer 0.77 and feathered game 0.14. The mean value in the less frequent game amounted to 0.36 Bq/kg. The geometrical standard deviation (GSD) widely varied from 1.6 to 21 for the studied species. Based on mass activity dependence on time, we assessed the effective and environmental half-lives of activity decline. For red deer and roe deer, the effective (137)Cs half-life was 2.9 and 3.2 years, and environmental half-life 3.2 and 3.6 years respectively. The effective half-life of (137)Cs in wild boar of 38 years was determined with large uncertainty and it shows constant influx of (137)Cs activity to the digestive tract of wild boars. A statistically significant season-based (137)Cs level was found in red deer and wild boar. Higher winter and spring activities of (137)Cs in wild boar are linked with decreasing access to naturally occurring food with lower (137)Cs content (chestnuts, acorns, and beech nuts), making boar grub around for ground-deposited food (often for mushrooms with higher activity). Higher winter activities of (137)Cs in red deer meat, most probably, are due to lower access to green diet in winter. The average annual committed effective dose for Czech population based on estimates of game species meat consumption between 2004 and 2012 was insignificant, only 0.03 μSv.

    Loess-paleosol sequences preserve information that can be used to reconstruct paleoenvironement, specifically the climatic conditions and the vegetation present at the time of their formation, or determine their age. A dense network of reliably analyzed sequences from different geographic locations is crucial for representation of ecological and climatic trends during the Pleistocene (Frechen, 2011). The aim of this study is to fill the gap in the geographical distribution of well described loess-paleosol sequences in Central Europe. Therefore, it focuses on a loess-paleosol sequence in Bůhzdař, situated 9 km NW of Prague, Czech Republic. This profile was last studied in 1952 by naturalist Vojen Ložek. This study uses a number of analyses in order to get a multi-proxy record of local paleoenvironmental changes archived in a sequence of alternating loess sediments and paleosols in Bůhzař. Geochemical approaches are combined with paleozoology to define climatic conditions at the time of formation of the strata. Oxygen isotope 18O values of pedogenic carbonates can be used as a proxy of climatic factors such as temperature and precipitation, whereas carbon isotope values can be used to reconstruct changes in the atmospheric CO2 concentration (Obreht et al. 2013), perhaps also the relative proportions of plants using C3 and C4 metabolic pathways (Kaakinen et al., 2006). Findings of fossil malacofauna, which occupied specific ecological niches, can complement these results. The Bůhzdař locality is exceptional in terms of density of pedogenic carbonates, such as loess dolls, pseudomycelia and marl concretions. These concretions are, in some parts, more compact and form a compact layer. Analysis of pedogenic processes could bring new clues regarding the understanding of the way various forms of carbonates were formed. The analyses are in progress and the first results will be presented during an EGU session in April 2016. References Frechen, M. ed. (2011). Loess in

    The health of human populations living in industrial regions is negatively affected by exposure to environmental air pollutants. In this study, we investigated the impact of air pollution on a cohort of subjects living in Ostrava, a heavily polluted industrial region and compared it with a cohort of individuals from the relatively clean capital city of Prague. This study consisted of three sampling periods differing in the concentrations of major air pollutants (winter 2009, summer 2009 and winter 2010). During all sampling periods, the study subjects from Ostrava region were exposed to significantly higher concentrations of benzo[a]pyrene (B[a]P) and benzene than the subjects in Prague as measured by personal monitors. Pollution by B[a]P, particulate matter of aerodynamic diameter <2.5 µm (PM2.5) and benzene in the Ostrava region measured by stationary monitors was also higher than in Prague, with the exception of PM2.5 in summer 2009 when concentration of the pollutant was significantly elevated in Prague. To evaluate DNA damage in subjects from both locations we determined the levels of bulky DNA adducts in peripheral blood lymphocytes using the (32)P-postlabeling method. Despite higher B[a]P air pollution in the Ostrava region during all sampling periods, the levels of B[a]P-like DNA adducts per 10(8) nucleotides were significantly higher in the Ostrava subjects only in winter 2009 (mean ± SD: 0.21 ± 0.06 versus 0.28 ± 0.08 adducts/10(8) nucleotides, P < 0.001 for Prague and Ostrava subjects, respectively; P < 0.001). During the other two sampling periods, the levels of B[a]P-like DNA adducts were significantly higher in the Prague subjects (P < 0.001). Multivariate analyses conducted among subjects from Ostrava and Prague separately during all sampling periods revealed that exposure to B[a]P and PM2.5 significantly increased levels of B[a]P-like DNA adducts in the Ostrava subjects, but not in subjects from Prague.

    The prevalence of child obesity in the Czech Republic has increased in the last several years, especially among school-aged children. While obesity trends are closely monitored in the Czech Republic, very little is known about the dietary habits and exercise behaviors of Czech children. The purpose of this study was to evaluate nutrient intakes and physical activity, as well as identify predictors of BMI-for-age in a sample of Czech school-aged children. Ninety-seven fourth, fifth and sixth graders and their parents from two large Czech cities participated in the study. Two 24-hour recalls provided total amount of energy, fat, percentage of energy derived from fat, dietary fiber, and servings of fruits and vegetables. Physical activity was measured by the Self-administered Physical Activity Checklist (SAPAC). Children consumed less energy and dietary fiber than suggested by Czech dietary recommendations. The proportion of energy that children consumed from fat was 28.5%. Children consumed 1.4 cups of fruit and 1.2 cups of vegetables. Children's physical activity levels fell within the current recommendations. Age was the only significant predictor of higher BMI-for-age. Poor dietary quality may be responsible for increasing rates of child obesity in the Czech Republic. Nutritional professionals in the Czech Republic should focus on increasing consumption of fruits, vegetables, and other high-fiber foods in order to reduce the risk for overweight among Czech children.

    Mn biogeochemistry was studied from 1994 to 2003 in a small forested catchment in the central Czech Republic using the watershed mass balance approach together with measurements of internal stores and fluxes. Mn inputs in bulk deposition were relatively constant during a period of sharply decreasing acidic deposition, suggesting that the Mn source was terrestrial, and not from fossil fuel combustion. Mn inputs in bulk deposition and Mn supplied by weathering each averaged 13 mg m-2 year-1 (26 mg m -2 year-1 total input), whereas Mn export in streamwater and groundwater averaged 43 mg m-2 year-1. Thus an additional Mn source is needed to account for 17 mg m-2 year -1. Internal fluxes and pools of Mn were significantly greater than annual inputs and outputs. Throughfall Mn flux was 70 mg m-2 year-1, litterfall Mn flux was 103 mg m-2 year -1, and Mn net uptake by vegetation was 62 mg m-2 year-1. Large pools of labile or potentially labile Mn were present in biomass and surficial soil horizons. Small leakages from these large pools likely supply the additional Mn needed to close the watershed mass balance. This leakage may reflect an adjustment of the ecosystem to recent changes in atmospheric acidity. ?? 2007 Springer Science+Business Media B.V.

    Epidemiological evidence of lung cancer risk from radon is based mainly on studies of male miners. Recent results of one such study of Czech uranium miners who were restricted to lower exposure rates are reported. Two main factors that generally influence radiogenic risk of cancer, time since exposure and age at exposure, are analyzed. New analyses in the form of a relative risk model confirmed the strong decreasing effect with time since exposure that was observed earlier. In addition, a significant dependence on age at exposure was observed. This pattern of decreasing relative risk with increasing age at irradiation is consistent with observations in A-bomb survivors and irradiated patients. Similar analyses were performed for the two most frequent histological types of bronchogenic carcinoma, epidermoid and small cell. The general pattern of the risk for these two types was found to be similar to that for lung cancer overall. Nevertheless, differences were observed between these two types in the magnitude of the risk coefficients and in the latent period. The effect of radon exposure was found to be stronger but briefer for the small cell type. The effect of smoking was not examined in this study, as such data were not available.

    Background. Listeria monocytogenes (LM) is currently the third most frequent pathogen of bacterial meningitis in adults. Methods. A prospective study of patients with LM meningitis in a Czech tertiary care hospital, carried out from 1997 to 2012. Results. Thirty-one patients were diagnosed with LM meningitis, which was 7% of a total of 440 adult patients with acute bacterial meningitis (ABM) over a 16-year period. Their median age was 63 years, range 26–80 years. Nineteen patients (61%) had underlying immunocompromising comorbidity; 15 patients (48%) were older than 65 years. Fourteen patients (45%) had arterial hypertension. The typical triad of fever, neck stiffness, and altered mental status was present in 21 patients (68%). The median count of cerebrospinal fluid (CSF) leukocytes was 680/μL, protein level 2.6 g/L, and glucose ratio 0.28. Four patients (13%) died, and nine (29%) survived with moderate to severe sequelae. Conclusion. LM meningitis is known to affect immunosuppressed and elderly patients. Arterial hypertension seems to be another important predisposing factor.

    Coal is the only domestic source of fossil fuel in the Czech Republic. The coal reserves are substantial and their share in total energy use is about 60%. Presently necessary steps in making coal utilisation more friendly towards the environment have been taken and fairly well established, and an interest to develop and build advanced coal units has been observed. One IGCC system has been put into operation, and circa 10 AFBC units are in operation or under construction. Preparatory steps have been taken in building an advanced combustion unit fuelled by pulverised coal and retrofit action is taking place in many heating plants. An actual experience has shown two basic problems: (1) Different characteristic of domestic lignite, especially high content of ash, cause problems applying well-tried foreign technologies and apparently a more focused attention shall have to be paid to the quality of coal combusted. (2) Low prices of lignite (regarding energy, lignite is four times cheaper then coal) do not oblige to increase efficiency of the standing equipment applying advanced technologies. It will be of high interest to observe the effect of the effort of the European Union to establish a kind of carbon tax. It could dramatically change the existing scene in clean coal power generation by the logical pressure to increase the efficiency of energy transformation. In like manner the gradual liberalisation of energy prices might have similar consequences and it is a warranted expectation that, up to now not the best, energy balance will improve in near future.

    The area around the Pribram lead smelter has been recognized to be heavily contaminated by lead (Pb). In the early 1970s, several episodes of livestock lead intoxication were reported in this area; thereafter, several epidemiological and ecological studies focused on exposure of children. In contrast to earlier studies, the recent investigation (1992-1994) revealed significantly lower exposure to lead. From 1986-1990, recorded average blood lead levels were about 37.2 micrograms lead (Pb)/100 ml in an elementary school population living in a neighborhood close to the smelter (within 3 km of the plant). The present study, however, has found mean blood lead levels of 11.35 micrograms/100 ml (95% CI = 9.32; 13.82) among a comparable group of children. In addition to blood lead, tooth lead was used to assess exposure among children. Statistically significant differences (p < 0.05) were observed between the geometric mean tooth lead level of 6.44 micrograms Pb/g (n = 13; 95% CI = 3.95; 10.50) in the most contaminated zone and 1.43 micrograms Pb/g (n = 35; 95% CI = 1.11; 1.84) in zones farther away from the point source. Both biomarkers, blood and tooth lead levels, reflect a similar pattern of lead exposure in children. This study has attempted a quantitative assessment of risk factors associated with elevated lead exposure in the Czech Republic. Content of lead in soil, residential distance from the smelter, consumption of locally grown vegetables or fruits, drinking water from local wells, the mother's educational level, cigarette consumption among family members, and the number of children in the family were factors positively related (p < 0.05) to blood lead levels. The resulting blood lead level was found to be inversely proportional to the child's age. Images Figure 1. PMID:9189705

    On 30 January 2000, following the breach in the tailing dam of the Aurul SA Baia Mare Co., a major spill of about 100,000 m(3) of cyanide and metal-rich liquid waste was released into the river system near Baia Mare in northwest Romania. The pollutants flowed via different tributaries into the Tizsa (Tisa) river and finally through the Danube river into the Black Sea. Along the way pollutants (especially cyanides) caused rapid death of aquatic organisms and animals living close to the poisoned rivers. Following request from the governments of Romania, Hungary, and the Federal Republic of Yugoslavia, United Nations sent international mission experts to the area of accident. The Czech team of four experts took very active part in this mission. Samples of surface water collected by this team 3 weeks after the accident showed high toxicity in the rivers on the Romanian territory. Due to this impact, water from the Szamos river and a large area of the Tisza river in Hungarian territory was still medially toxic. Improvement of this situation was detected only in downstream areas of the Tisza/Tisa river. The high toxicity of surface water from the locality of the Lapos river upstream of the accident indicated the possibility of toxic pollution from other sources in the area. Aquatic sediments were highly toxic only in the Aurul reservoir and its surrounding area. Rapid decline of their toxicity indicated more limited adverse impact of the "Aurul pollution" in comparison with surface water. From ecotoxicological results it is evident that there is an urgent need to start abatement activities in the Baia Mare area because the possibility of future accidents still exists (this hypothesis was proved by further accidents on 10.3.2000 and the beginning of May 2000).

    2017-01-01

    Introduction Keratoconus is a relatively frequent disease leading to severe visual impairment. Existing therapies are imperfect and clinical management may benefit from improved understanding of mechanisms leading to this disease. We aim to investigate the replication of 11 single nucleotide polymorphisms (SNPs) with keratoconus. Methods SNPs from loci previously found in association with keratoconus were genotyped in 165 keratoconus cases of Caucasian Czech origin (108 males and 57 females) and 193 population and gender-matched controls. They included rs1536482 (COL5A1), rs4839200 (KCND3), rs757219 and rs214884 (IMMP2L), rs1328083 and rs1328089 (DAOA), rs2721051 (FOXO1), rs4894535 (FNDC3B), rs4954218 (MAP3K19, RAB3GAP1), rs9938149 (ZNF469) and rs1324183 (MPDZ). A case-control association analysis was assessed using Fisher’s exact tests. Results The strongest association was found for rs1324183 (allelic test OR = 1.58; 95% CI, 1.10–2.24, p = 0.01). Statistically significant values were also obtained for rs2721051 (allelic test OR = 1.72; 95% CI, 1.07–2.77, p = 0.025) and rs4954218 (allelic test OR = 1.53; 95% CI, 1.01–2.34; p = 0.047) which showed an opposite effect direction compared to previously reported one. Conclusion Independent replication of association between two SNPs and keratoconus supports the association of these loci with the risks for the disease development, while the effect of rs4954218 warrants further investigation. Understanding the role of the genetic factors involved in keratoconus etiopathogenesis may facilitate development of novel therapies and an early detection. PMID:28207827

    The EMBO workshop ‘Functional Organization of the Cell Nucleus’ held in Prague at the Hotel of the Postgraduate School of Medicine was attended by 110 participants (49 invited speakers and 61 selected participants) from 22 countries. Such a full range of topics devoted to the cell biology of the nucleus has not been discussed previously in such an intimate meeting in Europe. The workshop not only offered an opportunity for junior scientists to benefit from having an international meeting within Europe and a chance to discuss their work with internationally recognized experts, but it also offered a unique opportunity for interactions among the more established investigators. The fruits of a number of presentations are gathered together in a Special Issue of the Journal of Structural Biology which appeared in spring 2000. Last but not least, it is worth mentioning that while stepping through a packed scientific program, the participants did find the time to observe the solar eclipse just before the lunch break of August 11.

    Biological properties (rct marker and antigenic relatedness) were compared in vaccine prototype strains and in 62 poliovirus strains isolated during a period 1969-1978 from the main municipal sewerage system of the City of Prague. None of the strains isolated from the municipal sewerage showed biologic properties that would fully differ from those observed in vaccine-derived strains. The strains detected very late postvaccination (after about a year) showed a lesser extent of changes than strains isolated earlier after vaccination. The most frequent changes were recorded in type 2 strains, less frequent in type 3 strains and the least frequency of changes was found in type 1 strains. To facilitate comparisons of these changes in dependence on time of postvaccination virus excretion a supporting evaluation criterion has been developed to help express the dynamics of changes in the isolated poliovirus strains. The recorded degree of the dynamics of changes was highest in type 2 strains, lower in type 3 strains and lowest in type 1 strains. The dynamics of changes detected in strains of various types was not always constant in the course of years: in a given year (or in a period of several years) changes occurred always in strains of the same serologic type, whereas strains of the other two types changed only insignificantly during the respective period.

The open data model supported the evidence of all treatments that were used in a certain place as well as (where appropriate) to store relevant information on the application of those treatments. The stored data should together answer the questions like "What amount of which treatment was used in a certain place?", "When it will be safe to apply another treatment?" or "Is the treatment registered and allowed in the European Union/Member State?" The FOODIE data model is based on INSPIRE specification for Agricultural and Aquaculture Facilities., The FOODIE data model is based on the Activity Complex model.. Within INSPIRE, "Activity Complex" denotes a generic name agreed across thematic domains trying to avoid specific thematic connotations such as "Plant", "Installation", "Facility", "Establishment" or "Holding". Such scope may be identified for this paper as the Nitrate Directive or Water Framework Directive A Collection of data was verified on within the FOODIE Czech pilot farm with 1'214 ha of arable land to obtain information about farm machinery management and agro-meteorological observation. Selected tractors and implements were equipped by telemetry units to record vehicle trajectory in the fields and a wireless sensor network was established to observe meteorological conditions within a two fields with cereals. For these such purposes, a novel data model was developed to manage both sensor data and farm records within one platform simultaneously with the client application, which allows end-users to make visualization and analysis of farm data. The Czech Pilot is addressed to improve management and logistic of farms and agriculture service companies, introducing new tools and crop management methods for reduction of environmental burden while maintaining production level.

    The External Quality Control System (EQAS) of laboratory activities in medical microbiology and parasitology was implemented in the Czech Republic in 1993 with coded sera samples for diagnosis of viral hepatitis and bacterial strains for identification distributed to first participating laboratories. The number of sample types reached 31 in 2003 and the number of participating laboratories rised from 79 in 1993 to 421 in 2003. As many as 15.130 samples were distributed to the participating laboratories in 2003. Currently, almost all microbiology and parasitology laboratories in the Czech Republic involved in examination of clinical material participate in the EQAS. Based on the 11-year experience gained with the EQAS in the Czech Republic, the following benefits were observed: higher accuracy of results in different tests, standardisation of methods and the use of most suitable test kits.

    2012-08-01

    Research has revealed that organic consumers share beliefs about positive health effects, environmentally friendly production and better taste of organic food. Yet, very little is known about the decisions of organic consumers in post-socialist countries with emerging organic food markets. In order to examine this area a representative data set (N=1054) from the Czech Republic was used. Target group of the study has become the Czech consumers that purchase organic food on regular basis. The consumers' behaviour was conceptualised with the use of the theory of planned behaviour (ToPB). Firstly, the ToPB model was tested, and secondly, belief-based factors that influence the decisions and behaviour of consumers were explored. The theory proved able to predict and explain the behaviour of Czech organic consumers. The best predictors of the intention to purchase organic food are attitudes towards the behaviour and subjective norms. Decisive positions in consumers' beliefs have product- and process-based qualities.

    Transmission of canine leishmaniosis (CanL) is described in three consecutive generations of female Boxers living in a non-endemic environment in the Czech Republic. Infection of the first generation female likely occurred during a breeding visit to Italy and the dog died with typical clinical signs of the disease but without definitive laboratory diagnosis. The second and third generation offsprings never left the Czech Republic, suffered from clinical CanL confirmed by polymerase chain reaction and serology, and were apparently infected by transplacental transmission. Persistence of CanL in the Czech Republic over 7 years with a suspected origin in an endemic region and progression of infection through subsequent generations in a non-endemic country exemplifies that this disease may establish itself also in areas where no obvious vectors are present.

The compositions of Saliceto's prescriptions are simplified in comparison with the then prescription habits and contain a greater number of chemical active ingredients. Preparation of ophthalmic drops by means of distillation or boiling on a water bath deserves special attention. The treatise was translated into Czech in the first half of the 15th century and provided the basis for Czech pharmaceutical terminology.

    2011-10-01

    Naive listeners' perceptual assimilations of non-native vowels to first-language (L1) categories can predict difficulties in the acquisition of second-language vowel systems. This study demonstrates that listeners having two slightly different dialects as their L1s can differ in the perception of foreign vowels. Specifically, the study shows that Bohemian Czech and Moravian Czech listeners assimilate Dutch high front vowels differently to L1 categories. Consequently, the listeners are predicted to follow different paths in acquiring these Dutch vowels. These findings underscore the importance of carefully considering the specific dialect background of participants in foreign- and second-language speech perception studies.

    The content of 35 elements was determined in moss samples collected at 250 sites in the Czech Republic (CZ) in 2000. Four main areas of increased element contents in moss were revealed in the CZ (southern Moravia, Czech part of the former Black Triangle I territory, industrial northeastern Moravia, and the surroundings of a smelting town in southwestern Bohemia). The bioindicated high levels of Al, Ce, Co, Ga, La, Li, Pr, S, Th, U, V and Y atmospheric deposition loads in southern Moravia have never been reported in any paper before. Correlations were found in element content in moss vs. altitude, precipitation sums and bedrock types of the moss sampling plots. The current variability of element content in the CZ moss samples can be explained by the operation of not more than six factors.

  7. Radon Dose Determination for Cave Guides in Czech Republic

    2008-08-07

    According to recommended approach there are six (from total of twelve) open-to-public caves in Czech Republic, reaching near to an effective lung-dose of 6mSv/year. A conservative approach for estimating the potential effective lung-dose in caves (or underground) is based on two season's measurements, using solid state alpha track detector (Kodak in plastic diffusion chamber). The obtained dataset is converted into an annual effective dose, in agreement with the ICRP65 recommendation, using the 'cave factor' 1.5. The value of 'cave factor' which depends on the spectrum of aerosol particles, or on the proportional representation of the unattached/attached ratio (6.5 : 93.5 for residential places, 13.6 : 86.4 for caves due to lower concentration of free aerosols) and on the equilibrium factor. Thus conversion factor is 1.5 times higher in comparison with ICRP 65. Is this correct? Because a more precisely determined dose value would have a significant impact on radon remedies, or on restricting the time workers stay underground, a series of measurement was initiated in 2003 with the aim to specify input data, computation and errors in effective dose assessment in each one of the evaluated caves separately. The enhancement of personal dosimetry for underground work places includes a study of the given questions, from the following points of view in each cave: continual radon measurement; regular measurements of radon and its daughters to estimate the equilibrium factor and the presence of free {sup 218}Po; regular indoor air flow measurements to study the location of the radon supply and its transfer among individual areas of the cave; natural radioactive element content evaluation in subsoil and in water inside/outside, a study of the radon sources in the cave; determination of the free fraction from continual unattached and attached fraction measurement (grid and filter); thoron measurement. Air flow measurements provide very interesting information about the origin

    Measurements of PM10, PM2.5 and PM1 and particle number concentration and size distribution were measured for 24 h on a platform of the Prague underground metro in October 2013. The three PM fractions were analysed for major and minor elements, secondary inorganic aerosols (SIA) and total carbon (TC). Measurements were performed both when the metro was inoperative and closed to the public (referred to as background), and when the metro was in operation and open to passengers. PM concentrations were elevated during both periods, but were substantially increased in the coarse fraction during hours when the metro was in operation. Average PM concentrations were 214.8, 93.9 and 44.8 μg m-3 for PM10, PM2.5 and PM1, respectively (determined gravimetrically). Average particle number concentrations were 8.5 × 103 cm-3 for background hours and 11.5 × 103 cm-3 during operational hours. Particle number concentrations were found to not vary as significantly as PM concentrations throughout the day. Variations in PM were strongly governed by passing trains, with highest concentrations recorded during rush hour. When trains were less frequent, PM concentrations were shown to fluctuate in unison with the entrance and exit of trains (as shown by wind velocity measured on the platform). PM was found to be highly enriched with iron, especially in the coarse fraction, comprising 46% of PM10 (98.9 μg m-3). This reduces to 6.7 μg m-3 during background hours, proving that the trains themselves were the main source of iron, most probably from wheel-rail mechanical abrasion. Other enriched elements relative to background hours included Ba, Cu, Mn, Cr, Mo, Ni and Co, among others. Many of these elements exhibited a similar size distribution, further indicating their sources were common and were attributed to train operations.

    The analysis of mtDNA haplogroup frequency in various populations is a tool for studying human history and population dynamics. The aim of this study is to map the frequency of major mtDNA haplogroups in 300 maternally unrelated individuals representing the Czech population of the central part of the Czech Republic. Eighteen polymorphic sites in the coding region of mtDNA were screened by PCR-RFLP to determine 11 mtDNA haplogroups and 5 subhaplogroups. The most frequent haplogroups were H (41%) and U (21%). Less frequent haplogroups were J and T, each with a frequency of 8%. Frequencies of other haplogroups (V, K, HV, W, preV, X, and I) did not exceed 5%. The results of our study reveal that the frequency of mtDNA haplogroups in the Czech population is similar to the frequencies obtained in other European countries, especially Poland, Germany, and Russia. On the contrary, significant differences in haplogroup frequency were found between the Czech and Finnish populations (haplogroups U, T, W) and populations from Bulgaria and Turkey (haplogroups H).

    Carbapenemase-producing Enterobacteriaceae and Pseudomonas spp. are increasingly reported in many countries all over the world. Due to the resistance of those bacteria to almost all antibiotics (e.g.beta-lactams, aminoglycosides, fluoroquinolones),treatment options are seriously limited. In the Czech Republic, the incidence of carbapenemase-producing Enterobacteriaceae seems to be low, restricted to only three cases detected between 2009 and 2010.Here, we describe molecular typing of 15 carbapenemase-producing Klebsiella pneumoniae isolates identified in the Czech Republic during 2011. Five VIM-1-producing isolates belonging to sequence type (ST)11 and one VIM-4-producing isolate of ST1029 have been detected. blaVIM-1 and blaVIM-4 as a part of class 1 integrons were chromosomally located or carried by a plasmid belonging to A/C replicon type (blaVIM-4). KPC-3-producing isolates of ST512, recovered from six patients, caused an outbreak. Three more isolates producing KPC-2 enzyme belonged to ST258. Both blaKPCgenes were part of the Tn4401a transposon carried on plasmids of the pKpQIL type. The isolates were resistant to all antibiotics tested except colistin and/or gentamicin.Four of these 15 strains were recovered from patients repatriated to the Czech Republic from Greece and Italy. This is the first report of outbreaks caused by carbapenemase-producing Enterobacteriaceae in the Czech Republic.

  20. The approaches to the didactics of physics in the Czech Republic - Historical development

    The aim of this paper is to describe approaches to the didactics of physics which have appeared in the Czech Republic during its development and to discuss mainly their relationships with other fields. It is potentially beneficial to the understanding of the current situation of the Czech didactics of physics and to the prognosis of its future development. The main part of the article includes a description of the particular approaches of the Czech didactics of physics, such as the methodological, application, integration and communication approaches described in chronological order. Special attention is paid to the relationships of the didactics of physics and physics itself, pedagogy and other fields. It is obvious that the methodological approach is narrowly connected to physics, while the application approach comes essentially from pedagogy. The integration approach seeks the utilization of other scientific fields to develop the didactics of physics. It was revealed that the most elaborate is the communication approach. This approach belongs to the concepts that have influenced the current didactical thinking in the Czech Republic to a high extent in other fields as well (including within the didactics of socio-humanist fields). In spite of the importance of the communication approach, it should be admitted that the other approaches are, to a certain extent, employed as well and co-exist.

    The aim of this contribution is to introduce the recently started three year's project named "Variability of Short-term Precipitation and Runoff in Small Czech Drainage Basins and its Influence on Water Resources Management". Its main goal is to elaborate a methodology and online utility for deriving short-term design precipitation series, which could be utilized by a broad community of scientists, state administration as well as design planners. The outcomes of the project will especially be helpful in modelling hydrological or soil erosion problems when designing common measures for promoting water retention or landscape drainage systems in or out of the scope of Landscape consolidation projects. The precipitation scenarios will be derived from 10 years of observed data from point gauging stations and radar data. The analysis is focused on events' return period, rainfall total amount, internal intensity distribution and spatial distribution over the area of Czech Republic. The methodology will account for the choice of the simulation model. Several representatives of practically oriented models will be tested for the output sensitivity to selected precipitation scenario comparing to variability connected with other inputs uncertainty. The variability of the outputs will also be assessed in the context of economic impacts in design of landscape water structures or mitigation measures. The research was supported by the grant QJ1520265 of the Czech Ministry of Agriculture, using data provided by the Czech Hydrometeorological Institute.

  1. Relationship between abortion and contraception: A comparative socio-demographic analysis of Czech and Slovak populations.

    PubMed

    Kocourkova, Jirina

    2016-01-01

    Before 1990, abortions were highly prevalent in Eastern Europe, including Czechoslovakia. After 1990, the Czech and Slovak populations experienced a significant decrease in the abortion rate. Because both states have complete statistics on abortion and identical histories of abortion legislation, trends in abortion rates between 1988 and 2008 can be compared in detail using standard and decomposition methods. Binary logistic regression with odds ratios and 95% confidence intervals were used to identify the variables associated with changes in attitudes toward abortion between 1991 and 2008. First, a convergence in abortion rates was confirmed, although a higher abortion rate among unmarried Czech women remained in 2008. In contrast, a divergence in contraceptive practices was found; Slovaks have significantly lagged behind Czechs in the use of modern contraceptives. Differentials in attitudes toward abortion significantly increased (p < .001). Additionally, although a decline in the abortion rate was achieved without legal restrictions to access to abortions, various factors were responsible for this outcome. In the Czech Republic, improvements in family planning and increasing awareness of reproductive health have played key roles in promoting responsible sexual behavior, whereas in Slovakia, the stronger influence of the Catholic Church has contributed to the prevention of abortions.

    Background This study presents antigenic and genetic characteristics of Neisseria meningitidis strains recovered from invasive meningococcal disease (IMD) in the Czech Republic in 1971–2015. Material and Methods A total of 1970 isolates from IMD, referred to the National Reference Laboratory for Meningococcal Infections in 1971–2015, were studied. All isolates were identified and characterized by conventional biochemical and serological tests. Most isolates (82.5%) were characterized by multilocus sequence typing method. Results In the study period 1971–2015, the leading serogroup was B (52.4%), most often assigned to clonal complexes cc32, cc41/44, cc18, and cc269. A significant percentage of strains were of serogroup C (41.4%), with high clonal homogeneity due to hyperinvasive complex cc11, which played an important role in IMD in the Czech Republic in the mid-1990s. Serogroup Y isolates, mostly assigned to cc23, and isolates of clonally homogeneous serogroup W have also been recovered more often over the last years. Conclusion The incidence of IMD and distribution of serogroups and clonal complexes of N. meningitidis in the Czech Republic varied over time, as can be seen from the long-term monitoring, including molecular surveillance data. Data from the conventional and molecular IMD surveillance are helpful in refining the antimeningococcal vaccination strategy in the Czech Republic. PMID:27936105

    This paper addresses the course, extent, and impacts of a windstorm that occurred on 20-21 December 1740, in the Czech Lands. The analysis is based on documentary data included in chronicles, "books of memory", memoirs, damage reports, urbaria, and cadastral records, as well as secondary sources. The windstorm started with a thunderstorm in the afternoon of 20 December, continued during the night, and was followed by a flood. It also appeared in documentary data from Bavaria, Thuringia, Saxony, Silesia, Slovakia, and Hungary. The event may be related to a cyclone north-west of the Czech territory moving to the east with an intense western flow over central Europe. The storm did great material damage to houses, farm buildings, churches, and forests and is recorded in various documentary sources for 85 places in the Czech Lands. The windstorm had a significant influence on the development of local plantation forestry (discussed in greater detail). Judging by territorial extent and damage done, this windstorm, compared to other similar events, has been classified as "the windstorm of the eighteenth century" in the Czech Lands. This contribution demonstrates the potential of documentary evidence for the elucidation of heavy windstorms in the pre-instrumental period in Europe.

  9. Reflections on the main schools of the world psychology in the Czech interwar psychology.

    PubMed

    Plháková, Alena

    2008-11-01

    The author deals with the reasons for the different level of acceptance of the three important psychological perspectives (Gestalt psychology, behaviorism, and psychoanalysis) in the Czech interwar psychology. Gestalt psychology was probably the most accepted approach, which was at least partly caused by its founding in the neighboring Germany. It was an academic perspective that was convenient for the professional ambitions of its representatives as well as for their endeavor to establish psychology as a serious scientific discipline. On the contrary, the acceptance of behaviorism was rather negative or indifferent. Czech psychologists perceived it as a predominantly foreign, extraneous school of thinking. They preferred the studies on consciousness and the method of introspection over empirical research. Psychoanalysis also has never taken deeper roots in Czechoslovakia. Some Czech intellectuals accepted the existence of unconsciousness but they criticized Freudian sexual symbolism (Peroutka, Capek). Negative attitudes of the politicians Masaryk and Benes also contributed to the cool reception of this school. With sporadic exceptions, the psychoanalytic thinking was developed only in a small Jewish-German-Czech circle.

    2015-04-01

    Water erosion is a main factor of degradation of soils used for agriculture in the Czech Republic. For landscape conservation purposes the soil erosion risk is defined here mostly by USLE (Wischmeier and Smith, 1978). Within USLE the precipitation impact on erosion is a function of rainfall kinetic energy and intensity represented by R-factor. In the Czech Republic historically and recently several research teams have analyzed rainfall data to assess R-factor. Till now not many European countries have performed detailed spatially distributed analyses of rain erosivities. Most studies use only simplified methods based on long-term rainfall averages or databases of only several station-datasets. The most recent study on rainfall erosivity spatial distribution over the Czech Republic was based on digital rain gauge data from automatic stations of the Czech Hydrometeorogical Institute. The erosive rains were derived from continuous 1 minute step 10-year rainfall data (2003-2012) from 245 stations. Based on the research recent annual R-factor values in the stations vary from 37 to 239 [N.h-1] (values over 100 are located in mountain regions with minimum of agricultural land). Average value is 69 [N.h-1.year-1]. For the Czech Republic the future prediction is based on 10km resolution ALADIN/CZ regional climate model. Within the EU FP6 project CECILIA it was coupled with GCM ARPEGE to provide a projection of future climate in two time slices, 2021-2050 and 2071-2100, according to the IPCC A1B emission scenario. Daily precipitation volumes and percentiles of maximal events allowed authors to develop R-factor maps of present and future scenarios. Based on the analyses we can conclude that average value for the whole territory of the Czech Republic will remain close to 70 [N.h-1.year-1] or even decrease for 2071-2100, but we can expect significant changes (30-40 % rise or decrease) for several large agricultural regions (eg. Southern Moravia). These changes will have impact

  12. Autosomal recessive limb-girdle muscular dystrophies in the Czech Republic

    2014-01-01

    Background Autosomal recessive limb-girdle muscular dystrophies (LGMD2) include a number of disorders with heterogeneous etiology that cause predominantly weakness and wasting of the shoulder and pelvic girdle muscles. In this study, we determined the frequency of LGMD subtypes within a cohort of Czech LGMD2 patients using mutational analysis of the CAPN3, FKRP, SGCA, and ANO5 genes. Methods PCR-sequencing analysis; sequence capture and targeted resequencing. Results Mutations of the CAPN3 gene are the most common cause of LGMD2, and mutations in this gene were identified in 71 patients in a set of 218 Czech probands with a suspicion of LGMD2. Totally, we detected 37 different mutations of which 12 have been described only in Czech LGMD2A patients. The mutation c.550delA is the most frequent among our LGMD2A probands and was detected in 47.1% of CAPN3 mutant alleles. The frequency of particular forms of LGMD2 was 32.6% for LGMD2A (71 probands), 4.1% for LGMD2I (9 probands), 2.8% for LGMD2D (6 probands), and 1.4% for LGMD2L (3 probands). Further, we present the first results of a new approach established in the Czech Republic for diagnosis of neuromuscular diseases: sequence capture and targeted resequencing. Using this approach, we identified patients with mutations in the DYSF and SGCB genes. Conclusions We characterised a cohort of Czech LGMD2 patients on the basis of mutation analysis of genes associated with the most common forms of LGMD2 in the European population and subsequently compared the occurrence of particular forms of LGMD2 among countries on the basis of our results and published studies.

  13. The role of coal in the economy of the Czech Republic

    SciTech Connect

    Doruska, J.

    1995-12-01

    The Czech Republic ranks among the countries with high total reserves of hard coal and lignite. Therefore coal always had and still has a significant role in covering the power demand of the Czech Republic. Transition of the national economy, based on the principles of the market economy and private ownership, affects among others also behavior of the mining companies. A strong emphasis is also aimed at the environmental aspects concerning both the process of coal mining and the process of its utilization. Within these intentions the power policy of the Czech Republic is formulated. The Czech Republic, which has 10 mil. inhabitants, ranks among the countries with a high share of industry in the process of creating the gross national product. This state has its historical roots as on the present territory of the Czech Republic there had been concentrated a majority of industrial and mining capacities of the Hapsburg Empire. The First World War resulted among others in the decline of the Hapsburg Empire. Within this process Czechoslovak Republic was established (apart from other things the center of democracy in the Central Europe). In that republic the industry had an important position. The industrial potential had been expanded even during the occupation of Czechoslovakia by Nazi Germany in the years 1939 - 1945. After the Second World War when Europe was divided into two political spheres Czechoslovakia became a significant industrial base of so called East Bloc. Such a development and the needs of the Eastern Bloc resulted in the intensive development of the heavy industry on the territory of Czechoslovakia.

    Background Germline mutations in the BRCA1 and BRCA2 genes have been shown to account for the majority of hereditary breast and ovarian cancers. The purpose of our study was to estimate the incidence and spectrum of pathogenic mutations in BRCA1/2 genes in high-risk Czech families. Methods A total of 96 Czech families with recurrent breast and/or ovarian cancer and 55 patients considered to be at high-risk but with no reported family history of cancer were screened for mutations in the BRCA1/2 genes. The entire coding sequence of each gene was analyzed using a combination of the protein truncation test and direct DNA sequencing. Results A total of 35 mutations in the BRCA1/2 genes were identified in high-risk families (36.5%). Pathogenic mutations were found in 23.3% of breast cancer families and in 59.4% of families with the occurrence of both breast and ovarian cancer. In addition, four mutations were detected in 31 (12.9%) women with early onset breast cancer. One mutation was detected in seven (14.3%) patients affected with both a primary breast and ovarian cancer and another in three (33.3%) patients with a bilateral breast cancer. A total of 3 mutations in BRCA1 were identified among 14 (21.4%) women with a medullary breast carcinoma. Of 151 analyzed individuals, 35 (23.2%) carried a BRCA1 mutation and 9 (6.0%) a BRCA2 mutation. One novel truncating mutation was found in BRCA1 (c.1747A>T) and two in BRCA2 (c.3939delC and c.5763dupT). The 35 identified BRCA1 mutations comprised 13 different alterations. Three recurrent mutations accounted for 71.4% of unrelated individuals with detected gene alterations. The BRCA1 c.5266dupC (5382insC) was detected in 51.4% of mutation positive women. The mutations c.3700_3704del5 and c.181T>G (300T>G) contributed to 11.4% and 8.6% of pathogenic mutations, respectively. A total of eight different mutations were identified in BRCA2. The novel c.5763dupT mutation, which appeared in two unrelated families, was the only recurrent

    Although the Czech Republic is not generally characterized as a drought prone region within European context, drought occurs and is one of the most important climatic extremes in terms of economic damages. Crop production is highly sensitive to soil water availability and the rainfed agriculture almost dominantly prevails in the Czech Republic. Generally we can observe trends towards drier conditions with more often and more severe drought episodes. Based on this, the impact analyzes are very important. The relationship between drought episodes (with various timing and severity) and observed decrease of yields at district level (NUTS4) during the period from 2000 to 2014 was analyzed within submitted study. The observed yields of spring barley, winter wheat and oilseed winter rape from 14 districts were used (210 seasons are included). All districts are positioned within southeastern part of the Czech Republic and represent various agro-climatic conditions. The regressions between various drought indicators (as independent variables) and yields (dependent variable) were established. For this purpose the several drought indicators in monthly time step were derived as spatial average for arable land (each district separately). The difference between precipitation and reference evapotranspiration (ET0), average soil moisture content available for crops up to 40 cm and 100 cm depth, percent of time with soil moisture below 50 % and below 30 % of available soil moisture up to 100 cm depth were used. For reference evapotranspiration (ET0) and soil water estimates SoilClim model was used. This software is the main module used within Drought monitoring system in the Czech Republic (www.intersucho.cz). Within this study SoilClim was used in resolution 500 x 500 meters within grids of arable land. The soil water holding capacity as well as vegetation development was considered. By this way the yield losses due to various drought intensity was identified and compared. In case

    While magnetoreception in birds has been studied intensively, the literature on magnetoreception in bony fish, and particularly in non-migratory fish, is quite scarce. We examined alignment of common carps (Cyprinus carpio) at traditional Christmas sale in the Czech Republic. The sample comprised measurements of the directional bearings in 14,537 individual fish, distributed among 80 large circular plastic tubs, at 25 localities in the Czech Republic, during 817 sampling sessions, on seven subsequent days in December 2011. We found that carps displayed a statistically highly significant spontaneous preference to align their bodies along the North-South axis. In the absence of any other common orientation cues which could explain this directional preference, we attribute the alignment of the fish to the geomagnetic field lines. It is apparent that the display of magnetic alignment is a simple experimental paradigm of great heuristic potential.

    The External Quality Control (EQC) system in activities of laboratories engaged in medical microbiology and parasitology was established in the Czech Republic in 1993 when to the first laboratories which applied coded serum samples were sent for diagnosis of viral hepatitis and bacterial strains for identification. In the course of years the number of control areas increased and in 2000 there were 31 and the number of those interested in participation in EQC increased from 79 in 1993 to 434 in 2000. This year a total of 13,239 samples will be sent to laboratories. Gradually thus almost all microbiological and parasitological laboratories concerned with examination of clinical material became involved. Seven-year experience with EQC in the Czech Republic revealed that gradually the results of various examinations became more accurate, that methods became standardized and the most suitable examination sets are used.

    Based on an anonymous questionnaire survey of a representative population group above 15 years of age in the Czech Republic (862 men and 857 women) the authors investigated also sociodemographic factors affecting attitudes of the Czech population to induced abortions. The findings suggest that attitudes of men and women to induced abortions do not differ essentially in any of the investigated criteria. The size of domicile does not affect the attitudes substantially. The most restrictive views are expressed by respondents of the oldest age group (above 60 years) and respondents of the youngest age group (15-17 years). The liberal attitude to induced abortions increases with the educational level. Religious belief has a marked effect on restrictive attitudes to abortions, nevertheless among catholic subjects only 7% male and female respondents expressed refused induced abortions unequivocally.

    During several recent years NRI Rez has been performing the LBB analyses of safety significant primary circuit pipings of NPPs in Czech and Slovak Republics. The analyses covered the NPPs with reactors WWER 440 Type 230 and 213 and WWER 1000 Type 320. Within the relevant LBB projects undertaken with the aim to prove the fulfilling of the requirements of LBB, a series of large scale experiments were performed. The goal of these experiments was to verify the properties of the components selected, and to prove the quality and/or conservatism of assessments used in the LBB-analyses. In this poster, a brief overview of experiments performed in Czech Republic under guidance of NRI Rez is presented.

    German patients in search of IVF with egg donation (which is prohibited by German law) are increasingly deciding to travel to clinics in other countries (mostly to the Czech Republic and Spain) that are able to provide them with the eggs of other women. Through three case studies of German couples who crossed international borders for IVF with egg donation, this article provides insight into these transnational practices aiming to circumvent restrictions in reproduction, whatever they may be. The material for this article is based on ethnographic fieldwork and interviews conducted in Germany, Spain and the Czech Republic, as well as research undertaken on IVF internet bulletin boards. The concepts of 'reproductive agency' and 'reproductive projects' are used to analyse the ways in which people search for information about treatments and clinics in other countries, how they embed the practice into their daily lives and how they deal with and position themselves regarding the need for reproductive travel.

    Crisis mapping is a legitimate component of both crisis informatics and disaster risk management. It has become an effective tool for humanitarian workers, especially after the earthquake in Haiti in 2010. Ushahidi is among the many mapping platforms on offer in the growing field of crisis mapping, and involves the application of crowdsourcing to create online and interactive maps of areas in turmoil. This paper presents the Crisis Map of the Czech Republic, which is the first such instrument to be deployed nationwide in Central Europe. It describes the methodologies used in the preparatory work phase and details some practices identified during the creation and actual employment of the map. In addition, the paper assesses its structure and technological architecture, as well as its potential possible development in the future. Lastly, it evaluates the utilisation of the Crisis Map during the floods in the Czech Republic in 2013.

    This paper presents an analysis of factors influencing job satisfaction in post-transition economies on the example of the Czech Republic. Our research shows that women reported higher levels of job satisfaction compared to men. Education proved to be statistically significant in one of three indicators of job satisfaction. Personal income and workplace relationships proved to be positively and significantly related to all the three indicators of job satisfaction. Most of the occupational dummies were significantly related to two out of three indicators of job satisfaction. In addition, we found that Czech entrepreneurs enjoy and value their job, which indicates strong self-selection for doing business in post-transition economies. However, human capital expressed by the level of education was significant factor for job satisfaction, meaning that well-educated people might not be satisfied with their jobs or feel that their education and experience are wasted in the market economy.

    A checklist is presented of the Orthoptera of the Czech Republic. Based on the critical revision of published data and previous lists of species, which often contained only general or questionable data and which often inaccurately cited each other, we found 96 species of Orthoptera belonging to the fauna of the Czech Republic. We emphasize those changes that are based on comparison with previous checklists. We provide information on missing, unclear, and extinct species and on newly detected species, and we confirm the status of species that have been missing for a long time (Leptophyes boscii, Polysarcus denticauda, Ruspolia nitidula, Eumodicogryllus bordigalensis, Tetrix bolivari, Mecostethus parapleurus). We also note those species for which only several individuals have been detected (Pteronemobius heydenii) or those survived only at a single locality (Platycleis montana, Aiolopus thalassinus, Dociostaurus brevicollis, Omocestus petraeus) or at two localities (Poecilimon intermedius, Platycleis veyseli, Pseudopodisma nagyi). Phaneroptera nana is recorded as new for Bohemia.

    It was consumed 48 -51 % of hard coal (total output 28 - 30 Mt/year) in a long period for the production of coke. It appears to be anomaly in comparison with other coke producers in Europe and in the world, it was predeterminated by {open_quotes}steel conception{close_quotes} of state`s economics. The production of coke reached 10-11 Mt/year in former Czechoslovakia in the period 1970-1990. A considerable quantity 1.2 - 1.7 Mt/year of produced coke was utilized for heating. In comparison, 7-5.4 Mt coke/year was it in Poland for the heating. Al coke production is realized on the basis of Czech hard coals mined in the southern part of Upper Silesian Coal District. The coke production is operated in multi-chamber system with full recovery of chemical products (gas, raw tar, raw benzene, amonium etc.). The future trend of smokeless fuel production in Czech Republic makes for to the non-recovery coke oven, it means to two-product processes (coke + reduction gas, coke + electricity and so on). Jewell--Thompson coke oven (hard coal) and Salem oven (ignites) represent nonrecovery nowadays. The possibility of it`s application in Czech Republic are discussed. Jumbo coking reactor system (European project No. 500 to the Eureka programme) produces primarily metallurgical coke. The strong Clean Air Act suspends the production of smokeless fuel in multi-chamber system also in Czech Republic for the future period 2010-2020.

    Major reforms in the Czech energy sector have been initiated to reverse 40 years of central planning, subsidized energy pricing, unchecked pollution from coal-fired plants, concerns over nuclear safety and fuel cycle management, and dependence on the former U.S.S.R. for oil, gas, and nuclear fuel processing. Prices for electricity, heat, and natural gas paid by industry are close to western levels, but subsidized prices for households are as much as 40% lower and below economic cost. State control of major energy enterprises is being reduced by moving toward government-regulated, investor-owned companies to raise needed capital, but with a strategic stake retained by the state. Foreign firms will participate in privatization, but they are not expected to acquire a controlling interest in Czech energy companies. Economic conditions in the Czech Republic are now improving after the disruptions caused by restructuring since 1989 and separation of the former Czech and Slovak Federal Republics in January 1993. The downturn in the economy after 1989 was concentrated in energy-intensive heavy industry, and recovery is paced by consumer trade, services, light industry and construction. Energy use in relation to gross domestic product (GDP) has declined, but it is still significantly higher than in OECD (Organization for Economic Cooperation and Development) countries. The GDP increased by 2% in 1994 after dropping 22% between 1989 and 1993. A positive balance of payments has been achieved, with foreign investment offsetting a small trade deficit. The government`s external debt is only 4% of GDP. This report studies the application of lignite resources within the newly formulated energy policies of the republic, in light of a move toward privatization and stronger air pollution regulations. Lignite has represented the major energy source for the country.

    A large-scale development in exploration and production of uranium ores in the Czech Republic was done in the 2nd half of the 20. century. Many uranium deposits were discovered in the territory of the Czech Republic. One of the most considerable deposits in the Czech Republic is the site Hamr na Jezere - Straz pod Ralskem where both mining methods - the underground mining and the acidic in-situ leaching - were used. The extensive production of uranium led to widespread environmental impacts and contamination of ground waters. Over the period of 'chemical' leaching of uranium (ca. 32 years), a total of more than 4 million tons of sulphuric acid and other chemicals have been injected into the ground. Most of the products (approx. 99.5 %) of the acids reactions with the rocks are located in the Cenomanian aquifer. The contamination of Cenomanian aquifer covers the area larger then 27 km{sup 2}. The influenced volume of groundwater is more than 380 million m{sup 3}. The total amount of dissolved SO{sub 4}{sup 2-} is about 3.6 million tons. After 1990 a large-scale environmental program was established and the Czech government decided to liquidate the ISL Mine and start the remediation in 1996. The remediation consists of contaminated groundwater pumping, removing of the contaminants and discharging or reinjection of treated water. Nowadays four main remedial technological installations with sufficient capacity for reaching of the target values of remedial parameters in 2037 are used - the 'Station for Acid Solutions Liquidation No. One', the 'Mother liquor reprocessing' station, the 'Neutralization and Decontamination Station NDS 6' and the 'Neutralization and Decontamination Station NDS 10'. It is expected that the amount of withdrawn contaminants will vary from 80 000 to 120 000 tons per year. Total costs of all remediation activities are expected to be in excess of 2 billion EUR.

    Objective measured trend data are important for public health practice. However, these data are rare for an adult population. Therefore, the aim of this study was to describe time trends in pedometer-determined physical activity of Czech adults (25–65 years) from 2008 to 2013. Participants were Czech national citizens whose physical activity was assessed objectively using a Yamax Digiwalker SW-700 pedometer (Yamax Corporation, Tokyo, Japan) for seven consecutive days in the period 2008 to 2013. The final sample was 4647 Czech adults [M age 41.4 ± 10 years; M body mass index (BMI) 25.1 ± 3.7 kg/m2]. The results showed that men took more steps/day (M (Mean) = 10,014; 95% CI (Confidence Interval) = 9864–10,164) than women (M = 9448; 95% CI = 9322–9673) in all age and BMI groups. Mean steps/day declined from 2008 to 2013 by 852 steps/day in men and 1491 steps/day in women. In the whole sample, the proportion of participants who had a sedentary lifestyle (<5000 steps/day) increased by 5.8%; the proportion taking ≥10,000 steps/day decreased by 15.8%. In 2013, men and women were 2.67 and 2.05 times, respectively, more likely to have a physically inactive lifestyle (<7500 steps/day) than in 2008. Conversely, in 2008, men and women were 1.68 and 2.46 times, respectively, less likely to have very active lifestyle (>12,500 steps/day). In conclusion, this study suggests that there has been a substantial reduction in physical activity in Czech adults over time. PMID:27783062

    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.

    Tularaemia, a zoonosis of veterinary and public health importance, commonly occurs in the Czech Republic as well as other countries of Northern Hemisphere. The objective of this study was to analyse the environmental conditions of distribution of natural foci of tularaemia and their long-term persistence in the Czech Republic. A geographic information system has been used for this purpose. A new variable (chi(t)), the mean number of natural foci in a specific area, has been suggested for the evaluation of diseases occurring in natural foci. Comparing two 15-year periods, a close correlation between the geographic distribution and numbers of natural foci of tularaemia in the Czech Republic in 1971-1985 and 1986-2000 (r = 0.91, n = 1814, t = 92.50, p = 0.01) was found. Natural foci of tularaemia have been persistent, but not stationary, over the period of 30 years and the geographic area of their occurrence has not been considerably growing or diminishing in the Czech Republic. The highest numbers of natural foci of tularaemia were in habitats of alluvial forests (chi(t) = 7.20), geographic areas of up to 200 m of elevation above sea (chi(t) = 9.18), 8.1-10.0 degrees C of mean annual air temperature (chi(t) = 6.24), 450-700 mm of mean annual precipitation (chi(t) = 2.84), and 2001-2200 hour of mean annual sunshine duration (chi(t) = 8.77). It was proved that tularaemia persists in specific areas of natural foci, the general environmental conditions of which can be defined and make it possible to predict the occurrence of tularaemia in other areas of suitable conditions.

    The social sciences within health care and pharmacy provide various points of view on issues often managed by professionals both inside and outside of the health care system. This multidisciplinary perspective often leads to divergent views and sometimes seemingly contradictory viewpoints and solutions. This paper is devoted to the opinions and attitudes of Czech citizens on selected issues of healthcare and pharmacy, the elucidation of which could be a source for understanding the relationships among participants in our pluralist health care system as a whole. This article presents the results of a sociological survey featuring a representative sample in terms of gender, age and region of 1,797 respondents from the Czech population aged 15 and over. The research is focused on the issues of self-medication, choice of pharmacy, out of pocket expenditures on prescription drugs and over-the-counter medicines, experiences with side effects and finally an evaluation of patient comprehension of information leaflets accompanying health care products. According to the results presented here, at the onset of a health problem most of the population tries to treat the condition themselves before seeing a doctor (54.1% always, 30.9% sometimes). Over-the-counter drugs are purchased generally in classic pharmacies without self-service (96.1%). The choice of pharmacy is determined primarily by proximity, with much less importance placed on personal experience or lower price. According to the survey, Czechs spend around 150 CZK (€ 5.9) for over-the-counter medicines and around 143 CZK (€ 5.6) for prescription drugs per month; 77.9% of Czech citizens were shown to understand the information provided on package leaflets. These data help to understand the perception, orientation and behavior of the patient in the healthcare system, with the ultimate goal of leading to higher system effectiveness as well as greater satisfaction for all parties involved.

    The study of droughts in the instrumental period can be based on various drought indices calculated usually from precipitation and temperature series. Documentary evidence, overlapping partly also with meteorological measurements, represents another important source utilisable particularly for the pre-instrumental period. Direct reports of drought or indirect indications of its impacts may be found in various individual or institutional sources: narrative written sources (annals, chronicles, commemorative records), weather diaries, personal and official correspondence, stall-keepers' and market songs, journalism, financial-economic records, religious sources (rogations, sermons, praying), special printed sources, chronograms, epigraphic sources ("hunger" stones). Corresponding data indicate directly meteorological drought and with describing of drought impacts also agricultural and hydrological droughts. The first credible direct drought information from the Czech Lands reports not any rain or snowfall during the 1090/1091 winter (Monk of Sázava). But data before AD 1500 are relatively scarce and they are related prevailingly to Bohemia. Density of precipitation/drought documentary records in the Czech Lands increases significantly after 1500. This allows create series of precipitation indices with classification of dry months in the scale -1 as dry, -2 as very dry and -3 as extremely dry month. Such dataset is important for the creation of 500-year Czech drought chronology.

    Clinical trials are an important part of clinical research. The conduction of clinical trials is strictly regulated and has to comply with an approved protocol. Local regulatory authorities, independent ethic committees, sponsors of clinical trials as well as the investigators are involved from the submission until the very end of the trial. All clinical trials performed in the Czech Republic have to be approved by the State Institute for Drug Control and by the Ethics Committee. The regulatory bodies and independent ethics committees evaluate and continuously supervise the justification and protocol of the clinical trial, quality of the investigational medicinal products and, primarily, the safety of the participants (patients and/or healthy volunteers) in clinical trials. In the Czech Republic there are many advanced clinical research centres, either located in private practices or within hospitals. The investigators are able to conduct a wide variety of clinical trials and recruit a high number of subjects for the trials, as well as to comply with the Good Clinical Practice guidelines and other regulatory requirements. The aim of this article is to summarise the current situation of clinical trials in the Czech Republic as well as the opportunities for getting involved in clinical trials and obligations arising for health professionals from such an involvement.

The survey was conducted by the National Institute of Public Health with financial support from the Ministry of Health and the Czech WHO office. Sociological survey replicated comparative research conducted in eight EU countries in the first half of this decade. Representative survey in 1037 respondents in the age over 16 years, selected in all regions of the country. The identical methodology as used in the original study was utilized. Health literacy was measured in the areas of health care, disease prevention and health promotion.We found that 59,4 % of respondents showed limited general health literacy; health literacy in health care is proved to be 49.5 % of the population, in the area of disease prevention it was 54.1 % respondents and in health promotion it was even even 64.3 % of respondents. Compared to the other countries surveyed, Czech Republic occupies the eighth, penultimate place. Health literacy is correlated negatively with age and positively with education. We found a strong social gradient of health literacy which rises with social status. Health literacy quite significantly influences the health status and health behaviors.Key words: health literacy, health behaviour, health promotion, social determinants of health.

    One hundred and twenty-seven exfoliative toxin-producing (ET-positive) strains of Staphylococcus aureus collected in 23 Czech and one Slovak maternity hospitals from 1998 to 2011 were genotypically characterized by multilocus sequence typing (MLST), pulsed-field gel electrophoresis (PFGE) profiling, spa gene polymorphism analysis, and ETA-converting prophage carriage, which resulted in the identification of 21 genotypes grouped into 4 clonal complexes (CC). Ninety-one isolates carried the eta gene alone whilst 12 isolates harboured only the etb gene. Two new, to date not defined, spa types (t6644 and t6645) and 2 novel sequence types (ST2194 and ST2195) were identified in the set of strains under study. The predominant CC121 occurred in 13 Czech hospitals. CC15, CC9, and ST88 (CC88) exclusively included eta gene-positive strains while the strains belonging to ST121 harboured the eta and/or etb genes. This study highlights not only significant genomic diversity among impetigo strains and the distribution of major genotypes disseminated in the Czech and Slovak maternity hospitals, but also reveals their impact in epidermolytic infections.

    Various sources of documentary evidence from Bohemian wine-growing region (NW part of the Czech Republic, CR) were used to compile series of grape-harvest dates (GHDs) for the 1499-2012 period. As the higher temperatures lead to earlier harvest dates and vice versa, GHDs series and mean Czech instrumental temperature series starting in 1801 were used to reconstruct mean April-August temperatures for the Czech Lands (recent CR) from 1499 to 2012. Ordinary least square (OLS) regression and variance scaling (VS) methods were used for calibration and compared as for explained variance and their ability to capture extreme values. The OLS does not underestimate temperature variability significantly and captures extremes well. The GHDs explain 79% of temperature variability in overlapping period. The 1971-2012 period, consistent with recent global warming, was identified as the warmest during the past 515 years. The highest April-August temperatures were reconstructed for the year 1540, which was warmer than two last very warm and more recent seasons in 2000 and 2003. The coldest period occurred at the beginning of the 20th century (1900-1929). The new reconstruction shows good agreement with existing Central European reconstructions that are based on different proxies. Reconstructed temperature series represents an important contribution to the better understanding of the long-term spatial-temporal temperature variability in Central Europe.

  18. Czech lesbian activism: gay and lesbian parental rights as a challenge to patriarchal marriage.

    In their advocacy for the legal recognition of same-sex relationships during the 1990s, prominent Czech gay rights activists focused only on issues of sexuality and did not question the essentialist understanding of gender, especially in parenting. Consequently, even though the Czech Republic legalized registered partnerships for gays and lesbians in 2006, legal barriers now exist regarding parental rights for same-sex couples, who are prohibited from adopting children and accessing reproductive technology once they register with the state. This article examines a rising, new wave of Czech lesbian activism that has focused on gaining legal parental rights for registered same-sex couples. While lesbian activists were disempowered in terms of their public visibility as well as political involvement during the 1990s, the recent growing prominence of lesbian groups has been enabled by their stronger political focus and organizational coherence. Analyzing the lesbian activists' strategies, I show not only how lesbian activism can advance the public debate about traditional gender roles, but also how lesbian activism can strengthen the critique of the ideology of marriage.

    The volume of waste electrical and electronic equipment (WEEE) has been rapidly growing in recent years. In the European Union (EU), legislation promoting the collection and recycling of WEEE has been in force since the year 2003. Yet, both current and recently suggested collection targets for WEEE are completely ineffective when it comes to collection and recycling of small WEEE (s-WEEE), with mobile phones as a typical example. Mobile phones are the most sold EEE and at the same time one of appliances with the lowest collection rate. To improve this situation, it is necessary to assess the amount of generated end of life (EoL) mobile phones as precisely as possible. This paper presents a method of assessment of EoL mobile phones generation based on delay model. Within the scope of this paper, the method has been applied on the Czech Republic data. However, this method can be applied also to other EoL appliances in or outside the Czech Republic. Our results show that the average total lifespan of Czech mobile phones is surprisingly long, exactly 7.99 years. We impute long lifespan particularly to a storage time of EoL mobile phones at households, estimated to be 4.35 years. In the years 1990-2000, only 45 thousands of EoL mobile phones were generated in the Czech Republic, while in the years 2000-2010 the number grew to 6.5 million pieces and it is estimated that in the years 2010-2020 about 26.3 million pieces will be generated. Current European legislation sets targets on collection and recycling of WEEE in general, but no specific collection target for EoL mobile phone exists. In the year 2010 only about 3-6% of Czech EoL mobile phones were collected for recovery and recycling. If we make similar estimation using an estimated average EU value, then within the next 10 years about 1.3 billion of EoL mobile phones would be available for recycling in the EU. This amount contains about 31 tonnes of gold and 325 tonnes of silver. Since Europe is dependent on import

    The main purpose of the first version of the computer system PERUN, which has been developed in 2001-2002 (presented in EGS 2002), is the probabilistic seasonal crop yield forecasting for a given site. The system is based on the crop growth model WOFOST (version 7, slightly modified) and the six-variate version of the stochastic weather generator Met&Roll. The system is now being enhanced to allow assessment of the crop yield potential of a larger area. As this assessment requires a great amount of meteorological, pedological and crop data to be gathered, but these data are not yet all available to the authors, the presentation will rather focus on the methodological aspects and the results of the sensitivity analysis. The presentation will consist of the following points: (i) Overview of the PERUN system. The results of the validation experiments (spring barley and winter wheat at selected Czech locations) will be presented, too. (ii) Methodology used for a spatial assessment. The assessment is based on integrating model crop yields simulated at multiple sub-regions with region-specific climatic and pedological conditions. The input daily weather series are produced by the stochastic generator. The multi-year crop model simulation is performed for each sub-region to assess the mean and variability of the model yields. (iii) Sensitivity of the regional crop production potential to uncertainties in selected input characteristics: crop cultivar, soil type, hydrological characteristics (e.g. amount of available water at the beginning of the simulation), and climatic conditions (e.g temperature, precipitation). In assessing sensitivity to climate, the climatic characteristics will be varied within the range of values typical for the territory of the Czech Republic. The crops applied in the analysis are spring barley and winter wheat.

    To a relativist, a time period equivalent to that of 60 orbits of the Earth around the Sun, or 5.676438379482·1019 cm of proper time, may not sound particularly significant. Yet, in our human society, it gives us the opportunity of honouring those we love and respect. Such was the occasion for the publication of this volume in honour of Professor Jiri Bicák of the Institute of Theoretical Physics at Charles University in Prague - a city in which Tycho Brahe and Kepler worked together, and where Einstein struggled to construct his general theory of relativity. An appropriate, but unusual, celebratory event which was organized on the relevant January evening involved an intersection of interesting time-shifted worldlines. A record of this is available at http://astro.troja.mff.cuni.cz/bicak/, which may help in comprehending the preface. Our purpose here, however, is to comment on the more permanent item that was produced for the occasion. It must immediately be stated that this is not a typical festschrift in which leading authorities around the world contribute articles dedicated to an academic colleague. It was a surprise present from past research students to their teacher. It maintains the character of a personal tribute but, basically, the contributions are research papers of the highest quality. The result is a very valuable academic reference. As Bicák would have wanted, this is a substantial contribution to objective science, not a piece of post-modern sentimentalism. Reflecting Bicák's own wide interests, the different contributions to this volume cover specific topics in general relativity, astrophysics, theoretical physics and cosmology. They include original articles and thorough up-to-date reviews. In all cases, detailed mathematical or computational analysis is guided by requirements of physical significance. The first paper is by Dolezel on observations from within slowly rotating voids in cosmological models and their compatibility with Mach

    A prognosis of how the information society in health care will look like in 2013 must start from the current state of affairs at the given locality regarding healthcare management by public authorities including legislative, ICT technological levels and accessibility of professional knowledge in individual fields of medicine. It is presumed that after 10 years the influence of this 'starting point' will still persist and knowledge of the current state of affairs will be needed to positively but also negatively differentiates the prognosis [Health Care in the Information Society: A Prognosis for the Year 2013, in this issue] for individual localities, e.g. Germany versus neighbouring the Czech Republic. The present article focuses on aims of Czech health care and the measures that are taken in Czech health care that are carried out and which have been already initiated. Their significance towards the future prognosis according to [Health Care in the Information Society: A Prognosis for the Year 2013, in this issue] is clear. The first measure is legalisation of conditions, which allow health care administration only be carried out with electronic forms and the protection of these sensitive personal data when they are placed in a centralised data depository where they are prepared for physicians who use them while providing health care in health institutions. In the Czech Republic an information system is developed called Internet Access to Health Patient Information (IHPI). The second measure is creating a unified central system of health information together with methodologies for data collection, data standards and protocols. In the Czech Republic there is the National Health Information System (NHIS) governed by the Institute for Health Information and Statistics (IHIS CR). The NHIS enables care providers to get information about the health state of citizens, about health institutions, about their activities and economics, it enables to regulate the provision of

    Of 34 breeds kept in the Czech Republic 45,604 sheep were genotyped for codons 136, 154 and 171 in the prion protein gene (PRNP) during the years 2006-2014. In this cohort, haplotypes ARR, ARQ, ARH, AHQ, VRQ, AHR and ARK were detected. The haplotype AF141RQ associated with susceptibility to atypical scrapie was observed in nine out of 30 breeds analysed for this purpose. In addition, six rare nonsynonymous substitutions producing haplotypes AT137RQ, AN138RQ, AG151RQ, AH151RQ, ARL168Q and ARQE175 were identified in various breeds. Due to their low frequencies, these polymorphisms are of no potential importance for the breeding programme. With regard to their genetic particularity, Sumavka, Valachian and Cameroon breeds were screened for additional polymorphisms. Further haplotypes, AR143RQ and AS146RQ, were found in Sumavka and Cameroon, and in Valachian sheep, respectively. Frequencies of the ARR (resistance-associated), VRQ (susceptibility-associated) haplotypes, and of the most resistant ARR/ARR genotype calculated for sheep born in the years 2001-2003 and 2011-2013 documented effects of the 10 year-lasting national breeding programme. The total frequency of ARR doubled from 36.8 to 75.8 %, while the frequency of VRQ decreased from 4 to 0.7 %. The total frequency of the ARR/ARR genotype increased from 17.7 to 59 %. These data show that the national scrapie resistance breeding programme has had an important desirable effect on haplotype and genotype frequencies of PRNP in Czech sheep.

More detailed attention is paid in particular to the development of the method of gastric bandings and the role at the First Surgical Department in this field in "classical" as well as miniinvasive surgery. Results of gastric banding are summarized in 683 patients operated since 1983, in particular the numbers of early and late complications after laparotomies and laparoscopic operations, similarly as complications which are directly associated with gastric banding itself. In the conclusion it is stated that the First Surgical Department of the General Faculty Hospital and First Medical Faculty Charles University in Prague belong as regards their results in surgical treatment of obese subjects and the position in the field of bariatric surgery on an international scale to the foremost departments in this field worldwide.

    The quantification of atmospheric deposition flux is essential for assessment of its impact on ecosystems. We present an advanced approach for the estimation of the spatial pattern of atmospheric nitrogen deposition flux over the Czech forests, collating all available measured data and model results. The aim of the presented study is to provide an improved, more complete, more reliable and more realistic estimate of the spatial pattern of nitrogen deposition flux over one country. This has so far usually been based on measurements of ambient NOx concentrations as dry deposition proxy, and [Formula: see text] and [Formula: see text] in precipitation as wet deposition proxy. For estimation of unmeasured species contributing to dry deposition, we used the CAMx Eulerian photochemical dispersion model, coupled with the Aladin regional numeric weather prediction model. The contribution of fog and dissolved organic nitrogen was estimated using a geostatistical data driven model. We prepared individual maps for particular components applying the most relevant approach and then merged all layers to obtain a final map representing the best estimate of nitrogen deposition over the Czech Republic. Final maps accounting for unmeasured species clearly indicate that the approach used so far may result in a substantial underestimation of nitrogen deposition flux. Our results showed that nitrogen deposition over the Czech forested area in 2008 was well above 2 g N m(-2) yr(-1), with almost 70% of forested area receiving 3-4 g N m(-2) yr(-1). NH3 and gaseous HNO3, contributing about 80%, dominated the dry nitrogen deposition. Estimating the unmeasured nitrogen species by modeled values provides realistic approximations of total nitrogen deposition that also result in more realistic spatial patterns that could be used as input for further studies of likely nitrogen impacts on ecosystems.

    The process of industrialization in the Czech Republic, which is more intensive than in other parts of central Europe, has been under way since the mid-nineteenth century. Over the last 40 years, large-scale industrial activity was based on extensive use of domestic primary energy sources, especially brown-coal/lignite. The escalation of this usage inflicted heavy devastation to large portions of industrial zones and, as a result, worsened living conditions through atmospheric pollution and other environmental impacts in large regions of central Europe. The Czech electricity industry and CEZ, a.s. (the nation`s principal electricity generator, responsible for meeting eighty percent of national electricity demand, and operator of the nationwide EHV transmission system) has been challenged to cope with all environmental issues by the end of 1997, in compliance with the strict limits set by the Clean Air Act of 1991, which are comparable to standard implemented in advanced industrial countries. A review of the critical environmental issues is presented and the role of the individual and of the State is analyzed. The approach of CEZ, a.s., towards a better natural environment and its response to legal environment provisions have been incorporated into the company`s development program. It comprises decommissioning the most obsolete fossil-fuel fired power stations; rehabilitation of thermal power plants; supplementing the coal/lignite-fired units selected for future operation with FGD systems and retrofitting them with DENOX equipment; a larger share of nuclear electricity generation after the completion of the Temelin NPP (2 units of 1000MW each) and, last but not least, initiating DSM (demand-side management) programs of energy-electricity savings in the Czech Republic.

    The main aim of this study was to determine and evaluate urinary excretion of uranium in the general public of the Czech Republic. This value should serve as a baseline for distinguishing possible increase in uranium content in population living near legacy sites of mining and processing uranium ores and also to help to distinguish the proportion of the uranium content in urine among uranium miners resulting from inhaled dust. The geometric mean of the uranium concentration in urine of 74 inhabitants of the Czech Republic was 0.091 mBq/L (7.4 ng/L) with the 95% confidence interval 0.071-0.12 mBq/L (5.7-9.6 ng/L) respectively. The geometric mean of the daily excretion was 0.15 mBq/d (12.4 ng/d) with the 95% confidence interval 0.12-0.20 mBq/d (9.5-16.1 ng/d) respectively. Despite the legacy of uranium mines and plants processing uranium ore in the Czech Republic, the levels of uranium in urine and therefore, also human body content of uranium, is similar to other countries, esp. Germany, Slovenia and USA. Significant difference in the daily urinary excretion of uranium was found between individuals using public supply and private water wells as a source of drinking water. Age dependence of daily urinary excretion of uranium was not found. Mean values and their range are comparable to other countries, esp. Germany, Slovenia and USA.

    Hailstorms belong to natural phenomena causing great material damage in present time, similarly as it was in the past. In Moravia (eastern part of the Czech Republic), systematic meteorological observations started generally in the latter half of the 19th century. Therefore, in order to create long-term series of hailstorms, it is necessary to search for other sources of information. Different types of documentary evidence are used in historical climatology, such as annals, chronicles, diaries, private letters, newspapers etc. Besides them, institutional documentary evidence of economic and administrative character (e.g. taxation records) has particular importance. This study aims to create a long-term series of hailstorms in South Moravia using various types of documentary evidence (such as taxation records, family archives, chronicles and newspapers which are the most important) and systematic meteorological observations in the station network. Although available hailstorm data cover the 1541-2014 period, incomplete documentary evidence allows reasonable analysis of fluctuations in hailstorm frequency only since the 1770s. The series compiled from documentary data and systematic meteorological observations is used to identify periods of lower and higher hailstorm frequency. Existing data may be used also for the study of spatial hailstorm variability. Basic uncertainties of compiled hailstorm series are discussed. Despite some bias in hailstorm data, South-Moravian hailstorm series significantly extends our knowledge about this phenomenon in the south-eastern part of the Czech Republic. The study is a part of the research project "Hydrometeorological extremes in Southern Moravia derived from documentary evidence" supported by the Grant Agency of the Czech Republic, reg. no. 13-19831S.

    Meteorological and hydrological extremes (hydrometeorological extremes - HMEs) cause great material damage or even loss of human lives in the present time, as well as it was in the past. For the study of their temporal and spatial variability in periods with only natural forcing factors in comparison with those combining also anthropogenic effects it is essential to have the longest possible series of HMEs. In the Czech Lands (recently the Czech Republic), systematic meteorological and hydrological observations started generally in the latter half of the 19th century. Therefore, in order to create long-term series of such extremes, it is necessary to search for other sources of information. There exist different types of documentary evidence used in historical climatology and hydrology, represented by various sources such as annals, chronicles, diaries, private letters, newspapers etc. Besides them, institutional documentary evidence (of economic and administrative character) has particular importance (e.g. taxation records). Documents in family archives represent further promising source of data related to HMEs. The documents kept by the most important lord families in Moravia (e.g. Liechtensteins, Dietrichsteins) are located in Moravian Land Archives in Brno. Besides data about family members, industrial and agricultural business, military questions, travelling and social events, they contain direct or indirect information about HMEs. It concerns descriptions of catastrophic phenomena on the particular demesne (mainly with respect to damage) as well as correspondence related to tax reductions (i.e. they can overlap with taxation records of particular estates). This contribution shows the potential of family archives as a source of information about HMEs, up to now only rarely used, which may extend our knowledge about them. Several examples of such documents are presented. The study is a part of the research project "Hydrometeorological extremes in Southern

    Environmental issues, especially the solution of the air pollution problem, have taken on great significance in the Czech Republic (which was a part of the Czech and Slovak Federal Republic until the end of 1992) since the 1989 {open_quotes}Velvet{close_quotes} Revolution. The former CSFR Federal Committee for the Environment and both the Republic Ministries started immediately with creating new environmental legislation, which is the main governmental tool for protecting the environment in the newly developing democracy state system with a market oriented economy. The inspiration for that activity was found in legislation of developed countries - member states of the European Union, and in German environmental law in particular. This paper surveys the major laws and regulations that gradually came into force in the Czech Republic since 1990. The provisions of the primary significance are the Act No.309/1991 S.B., dated July 9, 1991, on the protection of the air against pollutants - The Clean Air Act, the Act No.218/1992 S.B., dated April 27, 1992, which changes and supplements the Act No.309 - The Clean Air Act, the Measure of the Federal Committee for the Environment of October 1, 1991 to the Clean Air Act, and its amended wordings of June 23, 1992, 84/1991 S.B., and 84/1992 S.B., the Act No.389/1991 S.B., dated September 10, 1991 on the state administration of air protection and charges for the pollution of air, and several regulations based on the Act No.389/1991 S.B., issued in the period 1992 -1993.

    Typhus fever was a lethal disease of mankind. Elucidation of its origin and spread was due to more or less unscientific approaches at the time. Only in the second half of the 19th and at the beginning of the 20th century the period of a scientific approach to knowledge of its etiology, clinical aspects and epidemiology started. A great contribution was made in this respect by Czech doctors. The latter included Professor Hlava who made a series of experiments which were among the first which investigated the etiology of this disease. He may be therefore quite rightly included among one of the discoverers of the origin of typhus fever.

The oldest records of tornado occurrence in the region can be found in chronicles from the first half of the 12th century—the two most interesting of these are presented here in translation from the original Latin texts. Several other cases of possible tornadoes and waterspouts can be found in chronicles from the 12th and 13th centuries. However, from the descriptions of the events, it is not always clear if the phenomenon was a tornado, waterspout, dust swirl, or if it was of a non-tornadic nature. From the 14th to 19th centuries, tornado records are rather scarce for the region. However, this is likely to have a non-meteorological explanation. Gregor Mendel's (1871) essay " Die Windhose vom 13. October 1870" can be considered as a distinctive "breakpoint" in the documentation history of tornadoes in the territory of the present Czech Republic, followed later by the work of Edler von Wahlburg [Das Wetter 28 (1911) 135] and Wegener [Wind-und-Wasserhosen in Europa. F. Vieweg & Sohn, Braunschweig, 1917]. During the "socialist" period, the term " tornado" was seldom used and they were poorly understood, producing a view that "tornadoes do not occur in Central Europe". The situation began to change with the works of Munzar [Tromby (tonáda) na územı´ Èeské republiky v letech 1119-1993. Zbornı´k Dejin Fyziky, vol. XI. Voj. Akadémia SNP, Liptovský Mikuláš, pp. 69-72, 1993 (in Czech)] and Šálek [Meteorol. Zpr. 47 (1994) 172], and new records showed that about one tornado per year occurred between 1994 and 1999. Finally, between 2000 and 2002, the number of documented tornadoes in the Czech Republic was five to eight cases per year.

    Coal, rock and material conveying and men-riding presently represent the critical activities of the mining process. Coal when cut out in the face is continually transported towards the expedition from a mine. The selection of coal conveying system from face to the skip complex or directly to the surface depends mainly on the quantity of coal conveyed, the hauling distance, the local and time concentration of production and the lifetime of a system. Possibilities of belt conveying and combined belt conveying and locomotive haulage, used in Czech coal mines, are analyzed from the point of view of technological advantages and disadvantages and compared according to the economic parameters.

    Complex combustion research in the furnace of a high output boiler is part of complex research known as the Czech ``Clean Coal Technology`` program. Here the authors, are also testing results from three-dimensional mathematical and isothermal models. The results are used for simple burner alteration without additional financial requirements. The complex approach to these problems could lead to an increase in the capture of pollutants such as NO{sub x} (including N{sub 2}O), SO{sub x}, HF, HCl, heavy metals and hydrocarbons.

    We report a case of 54-year-old female, who was diagnosed with acute viral hepatitis E with uncomplicated anicteric course of the infection. The patient did not have a specific travel history to endemic areas and the infection has been acquired in the Czech Republic. The epidemiologic history was remarkable only because she consumed undercooked pork meat. A differential diagnostic process of acute viral hepatitis in our conditions as well as problems of acute viral hepatitis E as an autochtonous infection in Western and Central Europe are discussed.

    The key restriction of transplantation medicine globally, as well as in the Czech Republic, concerns the lack of organs. The number of deceased donors, and thus the availability of organ transplants, has been stagnating in our country. The paper describes current legal regulations governing the dia-gnosis of brain death and primary legal and medical criteria for the contraindication of the deceased for organ explantation, gives an overview of the number of liver transplants, age structure, and diagnosis resulting in brain death of the deceased liver donors in the Czech Republic.

  3. One language, two number-word systems and many problems: numerical cognition in the Czech language.

    Comparing numerical performance between different languages does not only mean comparing different number-word systems, but also implies a comparison of differences regarding culture or educational systems. The Czech language provides the remarkable opportunity to disentangle this confound as there exist two different number-word systems within the same language: for instance, "25" can be either coded in non-inverted order "dvadsetpät" [twenty-five] or in inverted order "pätadvadset" [five-and-twenty]. To investigate the influence of the number-word system on basic numerical processing within one culture, 7-year-old Czech-speaking children had to perform a transcoding task (i.e., writing Arabic numbers to dictation) in both number-word systems. The observed error pattern clearly indicated that the structure of the number-word system determined transcoding performance reliably: In the inverted number-word system about half of all errors were inversion-related. In contrast, hardly any inversion-related errors occurred in the non-inverted number-word system. We conclude that the development of numerical cognition does not only depend on cultural or educational differences, but is indeed related to the structure and transparency of a given number-word system.

    (137)Cs is one of the most important radionuclides released in the course of atmospheric nuclear weapon tests and during accidents in nuclear power plants such as that in Chernobyl, Ukraine, or Fukushima, Japan. The aim of this study was to compare (137)Cs and (40)K concentrations in particular species of mushrooms from selected locations in the Bohemian Forest (Czech: Šumava), Czech Republic, where a considerable contamination from the Chernobyl accident had been measured in 1986. Samples were collected between June and October 2014. Activities of (137)Cs and (40)K per dry mass were measured by means of a semiconductor gamma spectrometer. The (137)Cs values measured range from below detection limit to 4300 ± 20 Bq kg(-1), in the case of (40)K from 910 ± 80 to 4300 ± 230 Bq kg(-1). Differences were found between individual locations, due to uneven precipitation in the course of the movement of the radioactive cloud after the Chernobyl accident. There are, however, also differences between individual species of mushrooms from identical locations, which inter alia result from different characteristics of the soil and depths of mycelia. The values measured are compared with established limits and exposures from other radiation sources present in the environment. In general, it can be stated that the values measured are relatively low and the effects on the health of the population are negligible compared to other sources of ionizing radiation.

    The principal aim of our study was to present norms for old and very old Czech adults on the Czech version of the Montreal Cognitive Assessment (MoCA) and investigate the influence of social and demographic factors on MoCA performance. We analyzed 540 adults aged ≥ 60 years (5-year age categories; nationally representative sample in terms of sex and educational level), who met strict inclusion criteria for the absence of neurodegenerative disorders and performed within normal range in neuropsychological assessment. Using multiple regression model, we found that MoCA performance was affected by age and education (both p < .001) but not sex. The study provides normed percentile estimates for MoCA performance stratified by age (60-74 years; ≥ 75 years) and education lower versus higher. We also present percentile equivalents for the MoCA and Mini-Mental State Examination (MMSE) for use in clinical practice. We found age- and education-related effects on MoCA performance which support the use of culturally adapted normative data.

    Background Gene polymorphisms encoding the enzyme NADPH–cytochrome P450 oxidoreductase (POR) contribute to inter-individual differences in drug response. Aim To estimate polymorphic allele frequencies of the POR gene in a Czech Slavic population. Materials & Methods The gene POR was analyzed in 322 Czech Slavic individuals from a control cohort by sequencing and HRM analysis. Results Twenty-five SNP genetic variations were identified. Of these variants, 7 were new, unreported SNPs, including two SNPs in the 5´flanking region (g.4965 C>T and g.4994 G>T), one intronic variant (c.1899 −20C>T), one synonymous SNP (p.20Ala=) and three nonsynonymous SNPs (p.Thr29Ser, p.Pro384Leu and p.Thr529Met). The p.Pro384Leu variant exhibited reduced enzymatic activities compared to wild type. Conclusion New POR variant identification indicates that the number of uncommon variants might be specific for each subpopulation being investigated, particularly germane to the singular role that POR plays in providing reducing equivalents to all CYPs in the endoplasmic reticulum.

    In the Czech republic, as well as in other areas, the bridges are of various age and various condition. It seems that more problems can be found on recently- built bridges, but this is due to the fact that the old ones are usually not monitored in such a detail or not at all. The aim of monitoring bridges is to find possible deformations before the deformations get large/significant to endanger the people and/or traffic. However, there are more deformation causes of the bridges, and most of them are reversible, such as thermal dilation, bending with load etc. The problem is to recognize these components from the irreversible deformations, and one needs a large dataset, covering at least 18 month data (to separate the thermal dilation component from the linear deformation component). The direction of the irreversible movements can be arbitrary, and due to the easily accessible Sentinel-1 data, we try to monitor the bridge from various directions.For improving the accuracy we plan to make experiment with corner reflectors to enhance the intensity, and therefore to lower the standard deviation of the movement, however this experiment will be evaluated in future.Our project monitors few bridges in the Czech republic, of various length and age.

    Outbreaks of locusts, probably Locusta migratoria, were once relatively frequent phenomena in Central Europe. Documentary evidence reaching back as far as the fourteenth century provides information about these events in the Czech Lands. The stages of morphological development of locusts are influenced by a number of natural conditions, including climate. The question remains as to the extent to which the occurrence of locusts may be attributed to particular weather/climatic patterns in a given year (period) in Central Europe. Available documentary sources recording locust outbreaks in the Czech Lands are presented. The chronology thus created shows their occurrence peaked in the seventeenth century, followed in severity by the eighteenth and sixteenth centuries. Some of the largest outbreaks recorded (1338, 1474-1475, 1542-1546, 1693, 1712 and 1748-1749) are analysed in detail. Seasonal temperature and precipitation patterns in Central Europe during the years in which the locust outbreaks took place show no particular climatic features compared with the years without them, with the exception of cooler and wetter springs and wetter summers.

    Many children skip breakfast, consume soft drinks/sweets and do not eat the recommended amounts of fruit and vegetables. Poor eating habits in children tend to be carried over into adulthood. The changes in eating behaviours of Czech 11-, 13- and 15-year-old children were examined by frequency of breakfast (on weekdays and weekends), fruit, vegetable, sweet and soft drink consumption using data obtained from the Health Behaviour in School-aged Children (HBSC) surveys in 2002, 2006, 2010 and 2014. Logistic regression was used to analyze changes in eating behaviours. The findings showed a significant increase (only in girls, p ≤ 0.001) in prevalence of breakfast consumption (on weekdays) and a decrease in daily consumption of soft drinks (in boys and girls, p ≤ 0.001), sweets (in boys and girls, p ≤ 0.01) and fruit (in boys, p ≤ 0.01; in girls, p ≤ 0.001) between 2002 and 2014. Daily vegetable and breakfast on weekends consumption remained statistically unchanged over time. More frequent daily fruit, vegetable and breakfast (on weekends) consumption was reported by girls and younger children, whereas daily soft drink intake was more prevalent in boys and older children. There is a need for re-evaluation of current policies and new initiatives to improve the eating habits of Czech children. PMID:26694428

    Until 1990, contraception was free of charge for women in Czechoslovakia. Condoms were the only contraceptive which had to be paid for. Abortion was also free and was permitted for health and social reasons under certain circumstances. In 1987, Abortion Committees were abolished, and women were given the decision whether or not to have an abortion with only a time limit remaining (12 weeks of gestation). At this time, it was decided to charge fees for abortions performed after eight weeks of gestation. During this period, the use of modern contraceptive methods remained relatively low. When the Czech Republic was established as an independent state, fees were introduced for some health services including abortion and contraception. Abortions for health reasons remain free of charge. Health insurance schemes are being developed which cover the costs of some contraceptive supplies. Despite the initiation of fees, the number of induced abortions has slowly decreased since 1989, the number of births has decreased, and the use of modern contraceptives has increased. The priorities of the Czech Family Planning Association, therefore, are to identify target groups of women who do not use contraception and to increase the effectiveness of sex education.

    In the last few years, interest in the collection of data using remotely piloted aircraft systems (RPAS) has sharply risen. RPAS technology has a very wide area of use; one of its main advantages is its accuracy, timeliness of data, frequency of collecting data and low operating costs. RPAS can be used for the mapping of small, dangerous and inaccessible areas in contrast with ordinary aerial photogrammetry. In the cadastre of real estates of the Czech Republic, it is possible to map out areas by using aerial photogrammetry, so it has been done in the past. However, this is a relatively expensive and complex technology, and therefore we are looking for new alternatives. An alternative would be to use RPAS technology for data acquisition. The testing of the possibility of using RPAS for the cadastre of real estates of the Czech Republic is the subject of this paper. When evaluating results we compared point coordinates measured by geodetic method, GNSS technology and RPAS technology.

    Professor Karel Maydl was born in Rokytnice nad Jizerou, where his father was employed at the local court. Czech cardio-surgery was born with the first successful treatment of the stab in the heart, which was done by professor Rychlík in 1910. The next few years the cardio-surgery was represented only by occasional treatment of heart injury. Only in 1934 Jirí Divis excided ganglion stelatum to cure angina pectoris and in 1936 he performed surgical treatment of constrictive pericarditis. Article reviews all Essentials moments in the development of cardio-surgery in Bohemia and Moravia. The second part of the paper gives at present the most frequently performed surgeries. It is concluded that the Czech cardio-surgery has according to the numbers and duality of the treatment the west-European level. At the end Professor Maydl, who died for heart failure, is quoted, why he himself had to be stroked by the disease, which is not possible to treat with the knife. In the 100 years since that it is possible to evaluate that in ICEM 283 medical doctors have been treated for the heart disease and results of their operations were Berger than in standard population. It reproves the bad record of doctors to be bad patients.

    Although the research on cyberbullying has increased dramatically in recent years, still little is known about how cyberbullying participant groups (i.e., cyberbullies, cybervictims, and cyberbully-victims) differ from one another. This study aims to discriminate between these groups at an individual and relational level by controlling for age and gender. Self-control, offline aggression, and self-esteem are analyzed as individual-level variables. Parental attachment and peer rejection are involved as relational-level variables. A total of 2,092 Czech adolescents aged 12 to 18 were enrolled from a random sample of 34 primary and secondary schools located in the South Moravian region of the Czech Republic. Discriminant function analyses indicated that the participant groups are discriminated by two functions. The first function increases the separation between cyberbullies and cyberbully-victims from cybervictims, indicating that cyberbullies and cyberbully-victims are similar to each other in terms of low self-control, offline aggression, and gender, and have higher scores on measures of low self-esteem and offline aggression. However, cyberbully-victims had the highest scores on these measures. The second function discriminates between all three groups, which indicates that those variables included in the second function (i.e., parental attachment, peer rejection, self-esteem, and age) distinguish all three involved groups.

    Background Health literacy is a critical determinant of women’s and children’s health and therefore has immense consequences for the health of society as well. Evidence from epidemiological, clinical and experimental studies indicates that unhealthy lifestyles and risky behavioural habits of parents before conception and during pregnancy influence the etiology of various health defects. Decreasing primary risk factors, practicing physical wellness, monitoring physiological markers and preparing for labour, breastfeeding and newborn care should be the main parental responsibilities during the prenatal period. Methods Our study focused on specifying the main determinants of health literacy among 360 pregnant Czech women by using an anonymous questionnaire and selected anthropometric data of mothers. The criteria for study participation produced a sample representing 1.41% of Czech women in labour during a given 2012 reference period. Results Despite quite adequate knowledge of both risks and supporting factors for pregnancy and foetal development, the lifestyles of a majority of the women surveyed were far from optimum: only 30% reported good dietary and physical activity habits, 24% were active or passive smokers and one third of the women occasionally drank alcohol, more often among those who were university educated. Conclusion Our results have confirmed previously published data noting that health literacy and a healthier lifestyle of pregnant women are associated with a higher level of education (except for alcohol drinking) and with contact with a midwife (in some examined parameters) in prenatal courses.

    The morbidity and mortality rates in patients with cystic fibrosis (CF) are significantly affected by infections with Burkholderia cepacia complex. In a Czech CF Centre, the prevalence of the infection reached up to 30 %, with the majority of patients found to be infected with Burkholderia cenocepacia (formerly genomovar III of the Burkholderia cepacia complex). Since B. cenocepacia is associated with patient-to-patient transmission and epidemic outbreaks among CF patients, this study sought to examine the epidemiological relatedness between the Czech isolates belonging to the genomovar-homogeneous group. Eighty-three clinical isolates recovered from 67 CF patients were analysed using a random amplified polymorphic DNA (RAPD) assay and macrorestriction typing (SpeI and XbaI) followed by PFGE. A single predominant banding pattern shared by multiple isolates was detected, although SpeI-generated PFGE results yielded a higher rate of inter-pattern variability in comparison to the more uniform RAPD and XbaI-generated PFGE results for this clone. Both typing systems also showed that only three out of 67 patients harboured strains distinct from the major strain type. The dominant clone was characterized by PCR positivity for the B. cepacia epidemic strain marker, PCR negativity for the cable pilin subunit gene and close genetic relatedness to the epidemic strain of RAPD 01 type previously identified in Canada.

    This paper discusses the engineering considerations related to the design of a new 110 MWe atmospheric fluidized bed boiler (CFB) and boiler island auxiliaries for installation at the CEZ, a.s. (Czech Republic Utility) Ledvice Power Station. The plant is located in the northwest Bohemia area of the Czech Republic in the foothills of the Krusne Hory Mountains, between the towns of Bilina and Teplice. The type of fuel to be burned in the CFB is brown coal which requires unique design considerations in as well as the particular boiler operational parameters. The impetus behind the addition of this new CFB at the plant is that the existing pulverized coal fired steam generator which was put in service in 1969 is unable to meet new regulations and laws regarding compliance with the protection of the environment and will be replaced once the new CFB unit is brought into service. A technical-economic study conducted by CEZ, a.s. evaluated CFB technology as the most advantageous from a long-term standpoint. The following variations were considered in the study: boiler retrofit and construction of new ash handling equipment; implementation of the combined cycle based upon natural gas; and reconstruction of the boiler equipment with transition to atmospheric fluid-bed combustion. The selection of the supplier of fluid-bed boiler was performed with an emphasis of the bidders` references as for the construction and operation of fluid-bed boilers with the outputs of min. 300 t/hr.

    Mucopolysaccharidosis type II (Hunter syndrome, MPS II, OMIM 309900) is an X-linked lysosomal storage disorder caused by deficiency of iduronate-2-sulfatase (IDS). We analysed clinical and laboratory data from 44 Slavic patients with this disease. In total, 21 Czech, 7 Slovak, 9 Croatian and 7 Serbian patients (43 M/1 F) were included in the study (median age 11.0 years, range 1.2-43 years). Birth prevalence ranged from 1:69,223 (Serbia) to 1:192,626 (Czech Rep.). In the majority of patients (71%), the disease manifested in infancy. Cognitive functions were normal in 10 patients. Four, six and 24 patients had mild, moderate, and severe developmental delay, respectively, typically subsequent to developmental regression (59%). Residual enzyme activity showed no predictive value, and estimation of glycosaminoglycans (GAGs) had only limited importance for prognosis. Mutation analysis performed in 36 families led to the identification of 12 novel mutations, eight of which were small deletions/insertions. Large deletions/rearrangements and all but one small deletion/insertion led to a severe phenotype. This genotype-phenotype correlation was also identified in six cases with recurrent missense mutations. Based on patient genotype, the severity of the disease may be predicted with high probability in approximately half of MPS II patients.

    Many children skip breakfast, consume soft drinks/sweets and do not eat the recommended amounts of fruit and vegetables. Poor eating habits in children tend to be carried over into adulthood. The changes in eating behaviours of Czech 11-, 13- and 15-year-old children were examined by frequency of breakfast (on weekdays and weekends), fruit, vegetable, sweet and soft drink consumption using data obtained from the Health Behaviour in School-aged Children (HBSC) surveys in 2002, 2006, 2010 and 2014. Logistic regression was used to analyze changes in eating behaviours. The findings showed a significant increase (only in girls, p ≤ 0.001) in prevalence of breakfast consumption (on weekdays) and a decrease in daily consumption of soft drinks (in boys and girls, p ≤ 0.001), sweets (in boys and girls, p ≤ 0.01) and fruit (in boys, p ≤ 0.01; in girls, p ≤ 0.001) between 2002 and 2014. Daily vegetable and breakfast on weekends consumption remained statistically unchanged over time. More frequent daily fruit, vegetable and breakfast (on weekends) consumption was reported by girls and younger children, whereas daily soft drink intake was more prevalent in boys and older children. There is a need for re-evaluation of current policies and new initiatives to improve the eating habits of Czech children.

    Several flash floods occurred in the territory of the Czech Republic during the last decade of June and beginning of July 2009. These events caused vast economic damage and unfortunately there were also 15 fatalities. The complete evaluation of flash floods from the point of view of its meteorological cause, hydrological development and impacts was done under the responsibility of Ministry of Environment of the Czech Republic. Czech Hydrometeorological Institute (CHMI) coordinated this project. The results of the project contain several concrete proposals to reduce the threat of flash floods in the Czech Republic. The proposals were focused on possible future improvements of CHMI forecasting service activities including all other parts of Flood prevention and protection system in the Czech Republic. The synoptic cause of floods was the extraordinary long (12 days is longest in more than 60 years history) presence of eastern cyclonic situation over the Central Europe bringing warm, moist and unstable air masses from Mediterranean and Black Sea area. Very intensive thunderstorms accompanied by torrential rain occurred almost daily. Storm cells were organized in train effect and crossed repeatedly the same places within several hours. The extremity of the flood events was also influenced by soil saturation due to daily occurrence of rainstorms. The peak flows exceeded significantly 100-year of recurrence time in many sites. The observed and mainly unobserved catchments were affected. The detailed fields of rainfall amounts were gained from the adjusted meteorological radar observation. All of the available rainfall measurements at the climatological and rain gage stations were used for the adjustment. Hydraulic and rainfall-runoff models were used to evaluate the hydrological response. It was proved again, that the outputs from currently used meteorological forecasting models are not sufficient for a reliable local forecast of the strong convective storms and their

  1. Personalised, predictive and preventive medication process in hospitals—still rather missing: professional opinion survey on medication safety in Czech hospitals (based on professional opinions of recognised Czech health care experts)

    PubMed Central

    2014-01-01

    The survey had the following aims: (1) to rationalise the hypothesis that risks and losses relating to medication process' errors in Czech hospitals are at least comparable with the other developed countries and EU countries especially, (2) to get a valid professional opinion/estimate on the rate of adverse drug events happening in Czech hospitals, (3) to point out that medication errors represent real and serious risks and (4) to induce the hospital management readiness to execute fundamental changes and improvements to medication processes. We read through a lot of studies inquiring into hospitals' medication safety. Then, we selected the studies which brought reliable findings and formulated credible conclusions. Finally, we addressed reputable Czech experts in health care and asked them structured questions whether the studies' findings and conclusions corresponded with our respondents' own experience in the Czech hospital clinical practice and what their own estimates of adverse drug events' consequences were like. Based on the reputable Czech health care expert opinions/estimates, the rate of a false drug administration may exceed 5%, and over 7% of those cause serious health complications to Czech hospital inpatients. Measured by an average length of stay (ALOS), the Czech inpatients, harmed by a false drug administration, stay in hospital for more than 2.6 days longer than necessary. Any positive changes to a currently used, traditional, ways of drug dispensing and administration, along with computerisation, automation, electronic traceability, validation, or verification, must well pay off. Referring to the above results, it seems to be wise to follow the EU priorities in health and health care improvements. Thus, a right usage of the financial means provided by the EC—in terms of its new health programmes for the period 2014–2020 (e.g. Horizon 2020)—has a good chance of a good result in doing the right things right, at the right time and in the

    Evolutionary genetics has reached a new level of research thanks to the opportunity to study the genomes of not only present-day but also of ancient organisms. The obtaining of reliable data when working with ancient DNA is possible only in the case of interdisciplinary collaboration between archaeologists, paleontologists, molecular geneticists, and bioinformaticians. Despite laborious and high-cost technologies, the results never cease to amaze and can not only fill the gaps in the knowledge of the evolutionary history of different species but can also review the existing ideas on population development and dynamics. In this review, we discuss the history of the development of investigative techniques in ancient DNA research and the most striking results of these studies, including the most recent achievements.

    1997-12-01

    Ossification of the sesamoid bone of the first finger was studied in left hand-and-wrist X-rays of 296 Czech boys and 272 girls 9 to 15 years old using data collected between 1962 and 1966. The logit and the YES or NO methods were used in treating the data. A sesamoid bone, clearly visible to the naked eye, was considered as positive and when it was not yet visible, as negative. The sesamoid bone was developed in 50 per cent of boys at the age of 13.6 years and in 50 per cent of girls at the age of 11.2 years. This stage preceded the age at onset of menarche in Czech girls by 1.9 years. Boys showed a greater variability (SD = 1.4) than girls (SD = 0.8). Both sexes with clearly visible (ossified) sesamoid bones in their first fingers showed to be, on the average, taller and heavier in comparison with the Czech standard and with those boys and girls of corresponding ages without the sesamoid bone. In contrast to the still continuing secular trend in stature in Czech youths, the age of menarche remained in the last cca 30 years unchanged. In view of the close link between bone age and onset of menarche which remained unchanged for the past 30 years, we may consider our finding as still applicable to present-day adolescents.

    European brown hares (Lepus europaeus) coming from the Czech Republic, Slovakia and Austria were tested for serum antibodies against Neospora caninum by a competitive-inhibition enzyme-linked immunosorbent assay and for serum antibodies against Toxoplasma gondii by an indirect fluorescent antibody test. In a total of 925 samples, 280 (30%) and 132 (14%) reacted positively for N. caninum and T. gondii antibodies, respectively. Out of 333 hares in the Czech Republic, 129 (39%) and 71 (21%) reacted positively for N. caninum and T. gondii antibodies, respectively. Out of 209 hares in Slovakia, 8 (4%) and 13 (6%) reacted positively for N. caninum and T. gondii antibodies, respectively. Out of 383 hares in Austria, 143 (37%) and 48 (13%) reacted positively for N. caninum and T. gondii antibodies, respectively. Mixed infection (concurrent presence of both N. caninum and T. gondii antibodies) was found in 25 (8%) hares in the Czech Republic, in 14 (4%) hares in Austria and in none hare in Slovakia. It is the first report of antibodies against Neospora caninum in hares in the Czech Republic and Austria.

  3. Mercury accumulation in peatbogs at Czech sites with contrasting pollution histories.

    2012-05-01

    Mercury (Hg) concentrations and accumulation patterns were studied in (210)Pb-dated peat cores from three ombrotrophic sites in the Czech Republic with contrasting emission histories (Novodomské rašeliniště, ND, and Bílá Smědá, BS, in the polluted northern parts of the country, and Jezerní slať, JS, in a relatively pristine southern part of the Czech Republic). The Hg concentration varied significantly between sites. Whereas the sites in the northern part of the Czech Republic yielded a range of higher Hg concentrations (50-750 μg kg(-1) for ND and 30-600 μg kg(-1) for BS), a Hg concentration range of 40-220 μg kg(-1) was reported at JS. At the northern localities, the highest Hg concentrations were detected at depths of 5-10 cm, corresponding to the period between the early 1960s until the late 1980s. In contrast, the highest Hg values at JS were observed at a depth of 10-15 cm, corresponding to the period between the early 1950s and the early 1970s. The maximum Hg accumulation rates were approximately 2× higher at the northern localities (ND: 106 μg m(-2)yr(-1), BS: 90 μg m(-2)yr(-1), JS: 43 μg m(-2)yr(-1)). Although a decrease in the Hg concentration can be observed in the youngest segments of all the peat cores, a slight increase in Hg accumulation rates in the most recent peat segments (living Sphagnum moss) has been reported for all three sites (40-44 μg m(-2)yr(-1)), which is approximately 2× higher than in peat bogs in western and northern Europe. This observation may either be related to a real recent increase in Hg emissions in Central Europe (active coal mining and burning and limited Hg pollution control in thermal power plants) or could indicate a preferential Hg binding mechanism in the living moss at the surface of the peat.

    Remotely sensed vegetation indices by satellites are valuable tool for vegetation conditions assessment also in the case of field crops. This study is based on the use of NDVI (Normalized Difference Vegetation Index) and EVI (Enhanced Vegetation Index) derived from MODIS (Moderate Resolution Imaging Spectroradiometer) aboard Terra satellite. Data available from the year 2000 were analyzed and tested for seasonal yields predictions within selected districts of the Czech Republic (Central Europe). Namely the yields of spring barley, winter wheat and oilseed winter rape during the period from 2000 to 2014 were assessed. Observed yields from 14 districts (NUTS 4) were collected and thus 210 seasons were included. Selected districts differ considerably in their soil fertility and terrain configuration and represent transect across various agroclimatic conditions (from warm and dry to relative cool and wet regions). Two approaches were tested: 1) using of composite remotely sensed data (available in 16 day time step) provided by the USGS (https://lpdaac.usgs.gov/); 2) using daily remotely sensed data in combination with originally developed smoothing method. The yields were successfully predicted based on established regression models (remotely sensed data used as independent parameter). Besides others the impact of severe drought episodes within vegetation were identified and yield reductions at district level predicted (even before harvest). As a result the periods with the best relationship between remotely sensed data and yields were identified. The impact of drought conditions as well as normal or above normal yields of field crops could be predicted by proposed method within study region up to 30 days prior to the harvest. It could be concluded that remotely sensed vegetation conditions assessment should be important part of early warning systems focused on drought. Such information should be widely available for various users (decision makers, farmers, etc.) in

    RNF213/Mysterin has been identified as a susceptibility gene for moyamoya disease, a cerebrovascular disease characterized by occlusive lesions in the circle of Willis. The p.R4810K (rs112735431) variant is a founder polymorphism that is strongly associated with moyamoya disease in East Asia. Many non-p.R4810K rare variants of RNF213 have been identified in white moyamoya disease patients, although the ethnic mutations have not been investigated in this population. In the present study, we screened for RNF213 variants in 19 Slovakian and Czech moyamoya disease patients. A total of 69 RNF213 coding exons were directly sequenced in 18 probands and one relative who suffered from moyamoya disease in Slovakia and the Czech Republic. We previously reported one proband harboring RNF213 p.D4013N. Results from the present study identified four rare variants other than p.D4013N (p.R4019C, p.E4042K, p.V4146A, and p.W4677L) in four of the patients. P.V4146A was determined to be a novel de novo mutation, and p.R4019C and p.E4042K were identified as double mutations inherited on the same allele. P.W4677L, found in two moyamoya disease patients and an unaffected subject in the same pedigree, was a rare single nucleotide polymorphism. Functional analysis showed that RNF213 p.D4013N, p.R4019C and p.V4146A-transfected human umbilical vein endothelial cells displayed significant lowered migration, and RNF213 p.V4146A significantly reduced tube formation, indicating that these are disease-causing mutations. Results from the present study identified RNF213 rare variants in 22.2% (4/18 probands) of Slovakian and Czech moyamoya disease patients, confirming that RNF213 may also be a major causative gene in a relative large population of white patients.

    The aim of the study was to examine the prevalence and type of medicines used by high school students in the Czech Republic and to analyze association between use of medicines during last 6 months and self medication with different socio-demographic and lifestyle aspects. A cross-sectional study was conducted in high schools from two regions and three towns in the Czech Republic. The study sample was a student population of nine selected high schools. The study was approved by the local Ethics Committees and school board and was conducted in compliance with the ethical principles of the Declaration of Helsinki. Questionnaires respecting anonymity were distributed to the students during the regular class period. Students answered closed and open questions divided into six sections focussing on their experience with chronic and irregular use of medicines, medicines use during last six months, conditions treated, type and source of used medicines. A modified log-linear Poisson regression model with a robust variance estimator (sandwich) was used for statistical analysis. In total, 979 students, aged 14-21 years (mean age 17 years) participated in the study: 32% were male and 68% female; 19% of students reported regular use of medicines for chronic disease. The use of medicines during the last 6 months was reported by 83% of students; 42% of them reported the use of both prescription and over the counter (OTC) medicines; 22% the use only of OTC, and 31% only prescription medicines. Allergy, asthma, disorders of the thyroid gland, atopic dermatitis, and hypertensive diseases were among the most frequent long-term diseases. The most frequent groups of medicines used for the treatment of long-term diseases were systemic antihistamines, thyroid preparations, and respiratory drugs. Nonsteroidal anti-inflammatory medicines, ibuprofen and paracetamol were the most frequently used medicines during last six months. The study results showed quite extensive use of both

    The aim of this paper is to specify the cost of treatment and care for people with Alzheimer's disease (AD) in the Czech Republic and also with a view to the future. Data availability is evaluated as well as the quality of cost comparison with other developed countries. Data for the Czech Republic will include data from the health insurance company regarding medicines and treatment, as well as a selected home caring for people with dementia and, ultimately, the Social Security Administration. The basic methods include an analysis of data from publicly available sources, direct interviews with the representatives of nursing homes caring for people with dementia and the representative of the Social Security Administration of the Czech Republic. Items will be specified within the category of direct costs. For the study, the indirect costs related to the loss of patient as well as caring person productivity are not considered. Costs for treatment and care are based from the data on 4162 patients, the costs of a bed from data on 391 beds in homes for the elderly. The average annual cost per patient with AD in the Czech Republic was calculated and came to the amount of 12,783 EUR. These items include outpatient care, inpatient care in a medical facility, inpatient care in homes and medications. In terms of share of these items on the direct costs, the largest item are services provided by special homes which contributes to the direct costs by 94 %, medications create 1 % and treatment (both outpatient and inpatient) 5 %. In the case of home care the total costs are lower at 4698 EUR. The Czech Republic as well as other developed countries are faced with the problem of unified accounting cost of people suffering from Alzheimer's disease. This then causes the calculation of the economic burden to be very difficult and indicative values.

  8. March-June temperature reconstruction in the Czech Lands based on cereal harvest dates in the 1501-2008 period

    Cereal crop harvests reflect the weather patterns of the period immediately preceding them, and thus the dates at which they begin may be used as a source of proxy data on regional climate. Using systematic phenological observations in the Czech Lands (now known as the Czech Republic) after 1848, together with exploration of further surviving documentary evidence (chronicles, diaries, financial accounts etc.), it has proved possible to create series of winter wheat harvest dates for the period 1501-2008. Employing linear regression, the harvesting dates of the main cereal species (wheat, rye, barley, oats) were first converted to winter wheat harvest days and then normalised to the same altitude above sea level. The next step consisted of using series of winter wheat harvest dates to reconstruct mean March-June temperatures in the Czech Lands, applying standard palaeoclimatological methods. Series reconstructed by linear regression explain 70% of temperature variability. A profound cold period corresponding with late winter wheat harvests was noted between 1659 and 1705. In contrast, warm periods (i.e. early winter wheat harvests) were found for the periods of 1517-1542, 1788-1834 and 1946-2008. The period after 1951 is the warmest of all throughout the entire 1501-2008 period. Comparisons with other European temperature reconstructions derived from documentary sources (including grape harvest dates), tree-ring and instrumental data reveal generally close agreement, with significant correlations. Lower correlations around A.D. 1650 and 1750 may be partly related to deterioration of socio-economic conditions in the Czech Lands resulting from prolonged wars. The results obtained demonstrate that it is possible to use widely-available cereal harvest data for climate analysis and also that such data constitute an independent proxy data series for the region of Central Europe crucial to further studies of the potential impact of climatic variability and climate change

    The making of an end of life decision represents worldwide one of the most difficult issues that physicians can be confronted with --not only should it be regarded as consisting of medical and legal aspects, but ethics and moral values are present as well. Furthermore, it shall not be supposed that the economic parameter is negligible, unfortunately even to the contrary. The fact that the decision is often made by physicians under pressure caused by a system of limited resources (and therefore it can not avoid being distorted) must be kept in mind. At any rate , according to Czech law under which neither assisted suicide nor euthanasia is allowed, the legality and legitimacy of withdrawal and withholding of medical treatment is based on the argument of informed consent of the patient, advanced directives and the standard of lege artis treatment. These also shall be pleaded as defences in eventual criminal proceedings.

    2012-02-01

    Extemporaneously prepared products still have an irreplaceable role in therapy. In order to boost the magistral preparation, the availability of appropriate substances for the pharmacies must be ensured. This is due to the fact that many commercial pharmaceutical products containing these active ingredients do not comply with the individual requirements of a particular patient. Based on the practice requirements, the most requested substances have been chosen and within two years 16 pure substances with quality certificates have been provided for magistral preparation in pharmacies, and there are other chemicals coming. The increased availability of these chemicals should in particular eliminate the inappropriate and sometimes unlawful use of commercial medicinal products in extemporaneously prepared products. The paper presents 16 substances and formulations created by the authors, some of which are based on foreign formulations; however, they have been adapted to meet the requirements of the domestic environment. These products should create the basis of standardized formulations for preparation in pharmacies in the Czech Republic.

    In Czech Republic there is a long tradition of providing tertiary scholarships to students from developing countries. The government scholarship programme started in the 1950s already as a part of the Czechoslovak technical assistance to countries in the South. Even though the programme left tens of thousands of graduates all over the world, the recent programme evaluation has revealed that it is characterised by a relatively poor performance. This article brings forward the main outcomes of the programme evaluation, highlights the policy recommendations and summarises policy reflections that occurred following the evaluation. The programme evaluation was done under unfavourable circumstances and could be accordingly defined as 'shoestring evaluation'. The restrictions and their influence on evaluation outcomes are discussed in article, too.

    Iodopenia is importance world-wide problem--the cause of spectrum of iodine deficiency disorders (IDD). The "simple" way for its compensation is iodine supplementation--preferably by iodinization of salt: in the Czech Republic prevalence of IDD was very high in the past. The complex program for compensation of iodine deficiency realized in the CR includes improvement of salt iodization, supplementation of pregnant and lactating women, fortification of products for babies' nutrition and increasing use of iodinized salt in general population incl. food industry. Thus CR is country with compensated iodine deficiency according to criteria WHO, UNICEF, ICCIDD. In future, however, systematic interest should be focused on optimalization of iodine saturation, esp. in pregnant women and evaluation of possible risk of supranormal iodine intake (impairment of thyroid function, activation of thyroid autoimmunity). Taking in account, the changes of nutrition and life style systematic monitoring of quality of iodine supplementation seems to be essential.

    There is a long tradition in radiochemistry in the present Czech Republic that dates from 1856. However, the modern history of nuclear analytical techniques (NAT) development started after installation of the first experimental nuclear reactor and Van de Graaff accelerator in the mid-sixties at Rez. Since then, the NAT, such as neutron activation analysis (NAA) both instrumental (INAA) and radiochemical (RNAA), gamma activation analysis, particle-induced X-ray and gamma-ray emission (PIXE and PIGE, respectively), Rutherford backscattering, and neutron depth profiling have been continuously developed and applied in various scientific and technological fields. The radiochemical approach has always had a strong position in these investigations and resulted in the discovery of the substoichiometry separation principle in NAA and isotope dilution techniques and extensive utilization of RNAA. The use of INAA and RNAA in the evaluation of biological and environmental materials as well as plants is described.

    Guidelines for the management of obesity include recommendation about diet, exercise, behavioral modification, drug therapy and bariatric surgery in the comprehensive management of an obese patient. It is emphasized that the treatment of obesity should be individually tailored according to the age of the patient, degree and phase of obesity, body fat distribution and an expression of risk factors and comorbidities. The new realistic goals in obesity management do not focus on the weight loss per se but mainly on the risk factors reduction which accompanies even modest weight loss. The system of obesity management introduced in the Czech Republic includes obesity management centres attached to major teaching hospitals, obesity out-patient clinics (led by an obesity specialist), primary care physicians and weight reduction clubs. Postgraduate training in obesity management should be recognized by health authorities as a function specialty. A time demanding therapeutic strategy in obesity management should be taken into account by both health policy makers and health insurance companies.

    Ergosterol is considered to be a suitable indicator of mold infestation in barley and malt. In this study ergosterol levels in different varieties of barley and malt produced in the Czech Republic were determined. A modified high-performance liquid chromatography (HPLC) method was statistically processed, validated (Effivalidation program), and applied to 124 samples of barley and malt. Ergosterol was isolated by extraction and saponification, and the quantification was performed using HPLC with diode array detection. The content of ergosterol ranged between the limit of detection (LOD) and 36.3 mg/kg in barley and between the LOD and 131.1 mg/kg in malt. Ergosterol is presumably connected with metabolites generated when barley grain is attacked by pathogens, and such barley often shows a high overfoaming (gushing) value. However, it was found that the content of ergosterol does not correlate with the degree of beer gushing.

    Kriging is one of the geostatistical techniques for spatial data analysis that is usually used for a modelling of natural phenomena or a creation of digital elevation models. In this paper, we introduce kriging methods in the context of a landslide modelling in time. The proposed procedure, as well as most of the statistical methods, is designed for complete data sets, i.e. the observations at the beginning and the end of the study are available. In order to use all the information from the data and to avoid the loss of information after omitting observations with missing values, the algorithm for imputation of missing data values based on kriging techniques is proposed. The methodology was verified by the landslide modelling in Halenkovice, Czech Republic, during the period from June 2008 to March 2010. The obtained results showed a potential of kriging methods for the landslide modelling.

  17. Environmental security in the Czech Republic: Status and concerns in the post Communist era

    The Czech Republic has made great strides toward reconciling its political and economic development with environmental protection and security issues since its recent democratization. Although new technological and legislative efforts continue to work at reducing emissions from automobiles, industries, power plants and coal mining, the Republic is committed to continuing its battle against air and water pollution, poor waste management, and needless destruction of nature. Shifting the structure of primary energy sources to qualitatively better fuels, along with the introduction of less energy-consuming technologies and the activation of new nuclear reactors, would eventually replace most of the output of coal burning power plants. However, the use of nuclear power has been opposed by several political and environmental activists groups. At the international level, Austria`s opposition to the Temelin Nuclear Power plant is of great concern since Austria, as a non-nuclear state, propagates negative information about nuclear power to its citizens and other countries.

    Magnetotactic bacteria (MTB) are of considerable interest because of their importance in the manufacture of various bioinspired materials. In order to find out the status of magnetotactic bacteria at three different sediment in Czech Republic, samples collected from both standing and running freshwaters were subjected to molecular diversity analysis by using 16S rRNA gene approach. Total community DNA from sediment sample was isolated and used for PCR, cloning and sequence analysis. Of the 24 analyzed sequences, six clones are closely related to Magnetobacterium sp. affiliated with the Nitrospira phylum which showed the dominance of Magnetobacterium phylotypes in the sample. This study will provide useful insight about the community structure of MTB in this particular geographical region. However more detailed and specific studies are warranted in order to properly assess the community structure of MTB's in fresh water sediments.

    The objective of this study was to determine the coumarin content of ground cinnamon purchased from retail markets in the Czech Republic. No sample was labelled with information on the botanical source, but, in some cases, the countries of origin were specified. For comparison, a single cinnamon sample imported directly from a plantation in Sri Lanka that came from Cinnamomum verum was analyzed. Results from 60 ground cinnamon samples comprising twelve brands confirmed a high content of coumarin, with mean levels ranging from 2,650 to 7,017 mg · kg(-1). The high coumarin content confirmed that these cinnamon samples obtained from cassia cinnamon were in contrast to the sample from Sri Lanka, which was coumarin-free.

    Design principles for sub-slab depressurisation systems recently used in the Czech Republic for remediating existing buildings are described. Results of an efficiency analysis performed on the basis of data from >60 single-family houses are presented. It was found out that the efficiency varies between 70 and 98 %, which is twice greater than when additionally applied radon-proof insulation is used. The efficiency is mainly influenced by the vertical profile of the soil permeability and by the air-tightness of floors resting on the soil. Higher efficiency was found for houses with greater air-tightness of the floors and with a sub-floor layer with permeability higher than the permeability of the subsoil.

    The evolving debate on "urban shrinkage" mirrors an increasing interest in demographic phenomena on the part of urban scholars. This paper discusses ambiguous evidence about recent population decline in the large cities of Poland and the Czech Republic, with a particular focus on Łódz and Brno in general and their inner cities more specifically. By applying a mixed-method approach, the paper identifies indications of inner-city repopulation and socio-demographic diversification which are not yet apparent in register or census data. It is argued that there are indications of a silent transformation of traditional residential patterns and neighbourhoods in east central Europe. In the inner cities, this is reflected, amongst other things, by the presence of new households that may be called "transitory urbanites".

    Wild passerine birds (Passeriformes) from the northeastern part of the Czech Republic were examined for ectoparasites during the pre-breeding period in 2007. Two species of fleas of the genera Ceratophyllus and Dasypsyllus (Siphonaptera: Ceratophyllidae), and 23 species of chewing lice belonging to the genera Ricinus, Myrsidea, Menacanthus (Phthiraptera: Menoponidae), Brueelia, Penenirmus, and Philopterus (Phthiraptera: Philopteridae) were found on 108 birds of 16 species. Distribution of insect ectoparasites found on wild birds during pre-breeding was compared with previous data from the post-breeding period. There was no difference in total prevalence of chewing lice in pre-breeding and post-breeding periods. Higher prevalence of fleas and slightly higher mean intensity of chewing lice were found on birds during the pre-breeding period. There was a significant difference in total prevalence but equal mean intensity of chewing lice on resident and migrating birds.

    Since 2001, the absolute gravimeter FG5#215 has been used for modernization of national gravity networks in Czech Republic, Slovakia and Hungary. Altogether 37 absolute sites were measured at least once. In case of 29 sites, the absolute gravity has been determined prior to the FG5#215 by other accurate absolute meters (FG5 or JILA-g). Differences between gravity results, which reach up to 25 microgal, are caused by random and systematic errors of measurements, variations of environmental effects (mainly hydrological effects) and by geodynamics. The set of achieved differences is analyzed for potential hydrological effects based on global hydrology models and systematic errors of instrumental origin. Systematic instrumental errors are evaluated in context with accomplished international comparison measurements of absolute gravimeters in Sèvres and Walferdange organized by the Bureau International des Poids et Measures and European Center for Geodynamics and Seismology, respectively.

    Pericentric inversion of human chromosome 9 [inv(9)] is a relatively common cytogenetic finding. It is largely considered a clinically insignificant variant of the normal human karyotype. However, numerous studies have suggested its possible association with certain pathologies, e.g., infertility, habitual abortions or schizophrenia. We analysed the incidence of inv(9) and the spectrum of clinical indications for karyotyping among inv(9) carriers in three medical genetics departments in Prague. In their cytogenetic databases, among 26,597 total records we identified 421 (1.6 %) cases of inv(9) without any concurrent cytogenetic pathology. This study represents the world's largest epidemiological study on inv(9) to date. The incidence of inv(9) calculated in this way from diagnostic laboratory data does not differ from the incidence of inv(9) in three specific populationbased samples of healthy individuals (N = 4,166) karyotyped for preventive (amniocentesis for advanced maternal age, gamete donation) or legal reasons (children awaiting adoption). The most frequent clinical indication in inv(9) carriers was "idiopathic reproductive failure" - 37.1 %. The spectra and percentages of indications in individuals with inv(9) were further statistically evaluated for one of the departments (N = 170) by comparing individuals with inv(9) to a control group of 661 individuals with normal karyotypes without this inversion. The proportion of clinical referrals for "idiopathic reproductive failure" among inv(9) cases remains higher than in controls, but the difference is not statistically significant for both genders combined. Analysis in separated genders showed that the incidence of "idiopathic reproductive failure" could differ among inv(9) female and male carriers.

    The REVEALS model is a tool for recalculating pollen data into vegetation abundances on a regional scale. We explored the general effect of selected parameters by performing simulations and ascertained the best model setting for the Czech Republic using the shallowest samples from 120 fossil sites and data on actual regional vegetation (60 km radius). Vegetation proportions of 17 taxa were obtained by combining the CORINE Land Cover map with forest inventories, agricultural statistics and habitat mapping data. Our simulation shows that changing the site radius for all taxa substantially affects REVEALS estimates of taxa with heavy or light pollen grains. Decreasing the site radius has a similar effect as increasing the wind speed parameter. However, adjusting the site radius to 1 m for local taxa only (even taxa with light pollen) yields lower, more correct estimates despite their high pollen signal. Increasing the background radius does not affect the estimates significantly. Our comparison of estimates with actual vegetation in seven regions shows that the most accurate relative pollen productivity estimates (PPEs) come from Central Europe and Southern Sweden. The initial simulation and pollen data yielded unrealistic estimates for Abies under the default setting of the wind speed parameter (3 m/s). We therefore propose the setting of 4 m/s, which corresponds to the spring average in most regions of the Czech Republic studied. Ad hoc adjustment of PPEs with this setting improves the match 3–4-fold. We consider these values (apart from four exceptions) to be appropriate, because they are within the ranges of standard errors, so they are related to original PPEs. Setting a 1 m radius for local taxa (Alnus, Salix, Poaceae) significantly improves the match between estimates and actual vegetation. However, further adjustments to PPEs exceed the ranges of original values, so their relevance is uncertain. PMID:24936973

    We have developed an algorithm for identifying sudden changes in air pressure and temperature over the Czech Republic. Such events were retrieved from the data covering in 1986-2005 and were matched with the daily numbers of all-cause deaths and deaths due to cardiovascular diseases from the national database, separately for the whole population and that aged 70 years and over. Excess daily mortality was determined by calculating deviations of the observed number of deaths from the expected number of deaths for each day in the respective groups. The relative deviation of the mortality the mean was calculated as the ratio of the excess mortality to the expected number of deaths. We used 3-hour air pressure data from 10 meteorological stations and hourly air temperature data from 9 stations representative of the Czech Republic. Pressure changes were evaluated on time scales of 3, 6 and 12 hours, separately for summer and winter time. Temperature changes were evaluated on a 24-hour time scale, separately for summer and winter season. Events characterized by pressure or temperature changes above the critical threshold and recorded within 24 hours at more than 50% of meteorological stations were retrieved. The critical thresholds were defined separately for each station using quantiles of distributions of air pressure and temperature changes. Relative mortality deviations for days D-2 (2 days before the change) to D+7 (7 days after the change) were averaged over the retrieved events. Statistical significance of the mean relative deviation was tested using the Monte Carlo method. Increased mortality followed large temperature increases and large pressure drops both in summer and winter months. Decreased mortality was observed after large pressure increases and large temperature drops in summer. Mortality variations are usually more pronounced in the population aged 70 years and over, and cardiovascular diseases account for most deaths after sudden temperature changes.

    Myelodysplastic syndrome (MDS) is a common hematological disease in patients over sixty. Despite intensive research, the therapy of this heterogeneous blood disease is complicated. In recent years, two new therapeutic approaches have been proposed: immunomodulation and demethylation therapy. Immunomodulation therapy with lenalidomide represents a meaningful advance in the treatment of anemic patients, specifically those with 5q- aberrations. As much as 60-70% of patients respond and achieve transfusion independence. We present the initial lenalidomide experience of the Czech MDS group. We analyze Czech MDS register data of 34 (31 female; 3 male; median age 69 years) chronically transfused low risk MDS patients with 5q- aberration treated by lenalidomide. Twenty-seven (79.4%) patients were diagnosed with 5q- syndrome, 5 patients with refractory anemia with multilineage dysplasia, 1 patient with refractory anemia with excess of blasts 1, and 1 patient with myelodysplastic/myeloproliferative unclassified. Response, as represented by achieving complete transfusion independence, was achieved in 91% of patients. A true 5q- syndrome diagnosis in most our patients may be responsible for such a high response rate. Complete cytogenetic response was reached in 15% of patients and partial cytogenetic response in 67%, within a median time of 12 months. TP53 mutation was detected in 15% (3 from 18 tested) and 2 of these patients progressed to higher grade MDS. The majority of patients tolerated lenalidomide very well. Based on this albeit small study, we present our findings of high lenalidomide efficacy as well as the basic principles and problems of lenalidomide therapy.

  9. The influence of different types of grassland on soil quality in upland areas of Czech Republic.

    The diversity of grassland in upland areas of Czech Republic was studied on selected soil characteristics of these biotopes. In the first phase, 44 soil characteristics were studied and mutual correlations were found between many of them. In the following phase characteristics were chosen which correlated most with other soil characteristics and, at the same time, were easy to evaluate in practise. A great number of correlations were also evidenced between many soil characteristics and the content of humus and nitrogen, which are closely linked to organic matter in soil. In studying these characteristics on selected areas with different types of grassland and consequential cluster analysis and further evaluation, the grassland plots were divided into three groups, from newly established vegetation to species-rich communities. Non-parametric analysis was carried out on the results and a statistically significant difference was proved between the species rich and poorvegetation and carbon and nitrogen content of the soil. Slightly different humus quality (higher amount of HA) was also found under richer vegetation. These results show that at 0-20 cm layer, 58.9 tonnes of carbon ha⁻¹ was measured under species-poor pastureland and 106.1 tonnes of carbon ha under species-rich vegetation. The results showed that besides supporting species diversity, the described quality change can also be important for carbon sequestration. The difference of about 40-50 tonnes of carbon ha and converting 10% of grassland in the Czech Republic to species-rich vegetation would mean sequestration of about 3.9 Mt carbon. If only agroenvironmentally subsidized areas are converted, carbon sequestration in such vegetation could amountto 1.7 Mt.

  10. The use of taxation records in assessing historical floods in South Moravia, Czech Republic

    Since the second half of the 17th century, tax relief has been available to farmers and landowners to offset flood damage to property (buildings) and land (fields, meadows, pastures, gardens) in South Moravia, Czech Republic. Historically, the written applications for this were supported by a relatively efficient bureaucratic process that left a clear data trail of documentation, preserved at several levels: in the communities affected, in regional offices, and in the Moravian Land Office, all of which are to be found in estate and family collections in the Moravian Land Archives in the city of Brno, the provincial capital. As well as detailed information about damage done and administrative responses to it, data are often preserved as to the flood event itself, the time of its occurrence and its impacts, sometimes together with causes and stages. The final flood database based on taxation records is used here to describe the temporal and spatial density of both flood events and the records themselves. The information derived is used to help create long-term flood chronologies for the rivers Dyje, Jihlava, Svratka and Morava, combining floods interpreted from taxation records with other documentary data and floods derived from later systematic hydrological measurements (water levels, discharges). Common periods of higher flood frequency appear largely in the periods 1821-1850 and 1921-1950, although this shifts to several other decades for individual rivers. A number of uncertainties are inseparable from flood data taxation records: their spatial and temporal incompleteness; the inevitable limitation to larger-scale damage and restriction to the summer half-year; and the different characters of rivers, including land-use changes and channel modifications. Taxation data have considerable potential for extending our knowledge of past floods for the rest of the Czech Republic, not to mention other European countries in which records have survived.

    In the present paper, the rainfall erosivity factor (R factor) for the area of the Czech Republic is assessed. Based on 10 min data for 96 stations and corresponding R factor estimates, a number of spatial interpolation methods are applied and cross-validated. These methods include inverse distance weighting, standard, ordinary, and regression kriging with parameters estimated by the method of moments and restricted maximum likelihood, and a generalized least-squares (GLS) model. For the regression-based methods, various statistics of monthly precipitation as well as geographical indices are considered as covariates. In addition to the uncertainty originating from spatial interpolation, the uncertainty due to estimation of the rainfall kinetic energy (needed for calculation of the R factor) as well as the effect of record length and spatial coverage are also addressed. Finally, the contribution of each source of uncertainty is quantified. The average R factor for the area of the Czech Republic is 640 MJ ha-1 mm h-1, with values for the individual stations ranging between 320 and 1520 MJ ha-1 mm h-1. Among various spatial interpolation methods, the GLS model relating the R factor to the altitude, longitude, mean precipitation, and mean fraction of precipitation above the 95th percentile of monthly precipitation performed best. Application of the GLS model also reduced the uncertainty due to the record length, which is substantial when the R factor is estimated for individual sites. Our results revealed that reasonable estimates of the R factor can be obtained even from relatively short records (15-20 years), provided sufficient spatial coverage and covariates are available.

    Tachylytes from rift-related volcanic rocks were recognized as: (i) irregular veinlets in host alkaline lava flows of the Kozákov volcano, Czech Republic, (ii) (sub)angular xenoliths in alkaline lava of the feeding channel of the Bukovec volcano, Czech Republic, and (iii) paleosurface of a tholeiitic lava flow from Hafrafell, Iceland. The tachylyte from Kozákov is phonotephrite to tephriphonolite in composition while that from Bukovec corresponds to trachyandesite to tephriphonolite. Both glass and host rock from Hafrafell are of tholeiitic basalt composition. The tachylyte from Kozákov, compared with the host rock, revealed a substantial enrichment in major elements such as Si, Al and alkalis along with Rb, Sr, Ba, Nb, Zr, REE, Th and U. The tachylyte from Bukovec displays contrasting trends in the incompatible element contents. The similarity in composition of the Hafrafell tachylyte paleosurface layer and parental tholeiitic basalt is characteristic for lavas. The host/parent rocks and tachylytes have similar initial Sr-Nd characteristics testifying for their co-magmatic sources. The initial ɛNd values of host/parent rocks and tachylytes from the Bohemian Massif (+3.4 to +3.9) and those from Iceland (+6.3) are interpreted as primary magma values. Only the tachylyte from Bukovec shows a different ɛNd value of -2.1, corresponding to a xenolith of primarily sedimentary/metamorphic origin. The tachylyte from Kozákov is a product of an additional late magmatic portion of fluids penetrating through an irregular fissure system of basaltic lava. The Bukovec tachylyte is represented by xenoliths originated during the interaction of ascending basaltic melt with granitoids or orthogneisses, whereas the Hafrafell tachylyte is a product of a rapid cooling on the surface of a basalt flow.

    The study of the prevalence of erythromycin resistance in 22 169 S. pyogenes strains in the Czech Republic in 1996-2003 on the background of rough data on the nationwide consumption of macrolide antibiotics confirmed that the exponential growth of resistance observed in 1998-2001 copied with a delay the rise in macrolide antibiotic consumption recorded in 1992-1995. The highest frequency of erythromycin resistance was found in 2001 (16.5%) with a subsequent decrease to 14.5% in 2002 and to 9.1% in 2003. The drop in resistance followed the stagnation in macrolide consumption and its decrease by 17% in 2002. Upward and downward trends in macrolide resistance in different regions and age groups copied the nationwide trends with some quantitative differences that could not be analyzed in view of the lack of detailed data on antibiotic consumption. A 99.5% concordance was found between the results of the phenotypic method and those of detection of genes coding for constitutive, inducible and efflux resistance to macrolide-lincosamide-streptograminB (MLSB) antibiotics. In 2001 when the highest erythromycin resistance was recorded in the Czech Republic, most of the tested strains (91.2%) showed resistance to all MLSB antibiotics, with macrolide efflux (susceptibility to lincosamides and 16-membered macrolides was conserved) being implicated in resistance of 8.8% of the strains only. In 2003, the number of erythromycin resistant strains decreased and the resistance mechanism was ascribed to macrolide efflux in 26.8% of them. Almost all of the strains with constitutive or induced MLSB resistance are also resistant to either tetracycline or bacitracin or both. In the light of S. pyogenes resistance to bacitracin, the bacitracin disk is not usable in preliminary identification any more.

    The Czech Republic has a dense net of observatories, astronomical clubs and other activities for both adults and children. Can we use it to improve skills of our pupils and their motivation to choose their career in science? Does the situation in the Czech Republic differ from abroad? What can we improve in the future? These questions were not answered satisfactorily so far. We decided to contribute to solve this issue.We present our survey of current state based mainly on electronic sources and personal dealings. Besides of 56 observatories working with public and many interest clubs, there are other possibilities to meet astronomy. For example, Astronomical Olympiad attracts thousands of pupils across the country each year to solve both theoretical and practical tasks in astronomy. In other projects, children can visit Dark-Sky Parks, design experiments for a stratospheric balloon, observe with CCD or radio devices or build their own rockets.We outline our ongoing project to examine the link between popularization activities and pupils’ or high school students’ attitude toward science and science career. We plan to create a typology of both popularization activities and life stories of people dealing with astronomy. From the methodological point of view, the mixed method design, combining both the qualitative and quantitative approach, will be used to solve the research problems. The basic research plan will be a case study. So far the project is based on interviews with various subjects. We choose people with different life stories, all connected with astronomy or astronomy popularization in some period. We focus on important moments in their career, similarities between subjects, and various types of possible motivation to participate in astronomy-related activities or to study science at university.Future results can be used to help interested organizations such as universities, observatories or astronomical societies. They will be able to work more

    Insertion-deletion polymorphisms (INDELs) are diallelic markers derived from a single mutation event. Their low mutation frequency makes them suitable for forensic and parentage testing. The examination of INDELs thus combines advantages of both short tandem repeats (STR) and single nucleotide polymorphisms (SNP). This type of polymorphisms may be examined using as small amplicon size as SNP (about 100 bp) but could be analyzed by techniques used for routine STR analysis. For our population study, we genotyped 55 unrelated Czech individuals. We also genotyped 11 trios to analyze DIPplex Kit (QIAGEN, Germany) suitability for parentage testing. DIPplex Kit contains 30 diallelic autosomal markers. INDELs in DIPplex Kit were tested with linkage disequilibrium test, which showed that they could be treated as independent markers. All 30 loci fulfill Hardy-Weinberg equilibrium. There were several significant differences between Czech and African populations, but no significant ones within European population. Probability of a match in the Czech population was 1 in 6.8 × 10(12); combined power of discrimination was 99.9999999999%. Average paternity index was 1.13-1.77 for each locus; combined paternity index reached about 27,000 for a set of 30 loci. We can conclude that DIPplex kit is useful as an additional panel of markers in paternity cases when mutations in STR polymorphisms are present. For application on degraded or inhibited samples, further optimization of buffer and primer concentrations is needed.

    The aim of this paper is to describe the constitutional limits to the financing of health care and especially of public health insurance in the Czech Republic. It describes the current situation in the financing of health care on the basis of the Czech constitutional order as it has been interpreted by the Constitutional Court. Finally it presents an overview of the incorporation of the right to health into the constitutional documents of several European countries with the stress on the right to receive health care "free of charge". It is not typical within the European region to specify in constitutional acts to what extent it is giving the right to health care free-of-charge or more precisely to what extent and for what groups health care is paid for by persons other than by the citizens (patients). The Czech Republic is one of the exceptional cases in which the basic right to health care free-of-charge on the basis of public insurance is given directly by the Constitution.

    The aim of this study was to investigate the influence of selected soil characteristics on tree vitality at representative forest monitoring plots. We have chosen 20 stands with prevailing Norway spruce and 20 plots with dominance of European beech across the Czech Republic. Following soil characteristics were determined: pH, content of dissolved organic carbon (DOC), content of exchangeable (extracted by 0.1 M BaCl2) Ca, Mg and K, and major organic (formic, acetic and oxalic) and inorganic (e.g. sulphate and nitrate) anions in the aqueous extracts. Moreover, major Al forms in aqueous and 0.5 M KCl soil extracts were determined by means of HPLC/IC. Health of forest stands, expressed as crown defoliation, was assessed repeatedly. Overall, Al speciation in aqueous extracts was significantly affected by the DOC content and by the concentration of low molecular mass organic acids (LMMOA). The DOC content and composition is strongly dependent on tree species. We have observed higher proportion of organically bound Al in soil aqueous extracts under Norway spruce compared to European beech. This is probably caused by higher share of LMMOA from the total DOC content under Norway spruce. The health status of forest stands expressed as defoliation was negatively influenced by the contents of exchangeable Al3+ species and positively by the contents of exchangeable Ca and Mg in soils (Fig. 1). Potentially phytotoxic Al3+ was assessed as the prevailing Al exchangeable form. The beach stands is generally showed higher presence of Al3+, compared to the spruce stands. The Norway spruce stands exhibited different composition of DOC in soil, showing a higher share of LMMOA which might mitigate Al toxicity there. This study was supported by the Ministry of Agriculture of the Czech Republic (project no. QI92A216).

    We investigated the transit time distribution (TTD) of discharge collected from fractures in the Bedrichov Tunnel, Czech Republic, using lumped parameter models and multiple environmental tracers. We then utilize time series of δ18O, δ2H and 3H along with CFC measurements from individual fractures in the Bedrichov Tunnel of the Czech Republic to investigate the TTD, and the uncertainty in estimated mean travel time in several fracture networks of varying length and discharge. We also compare several TTDs, including the dispersion distribution, the exponential distribution, and a developed TTD which includes the effects of matrix diffusion. The effect of seasonal recharge is explored by comparing several seasonal weighting functions to derive the historical recharge concentration. We identify best fit mean ages for each TTD by minimizing the error-weighted, multi-tracer χ2 residual for each seasonal weighting function. We use this methodology to test the ability of each TTD and seasonal input function to fit the observed tracer concentrations, and the effect of choosing different TTD and seasonal recharge functions on the mean age estimation. We find that the estimated mean transit time is a function of both the assumed TTD and seasonal weighting function. Best fits as measured by the χ2 value were achieved for the dispersion model using the seasonal input function developed here for two of the three modeled sites, while at the third site, equally good fits were achieved with the exponential model and the dispersion model and our seasonal input function. The average mean transit time for all TTDs and seasonal input functions converged to similar values at each location. The sensitivity of the estimated mean transit time to the seasonal weighting function was equal to that of the TTD. These results indicated that understanding seasonality of recharge is at least as important as the uncertainty in the flow path distribution in

    The Czech Republic was heavily industrialized in the second half of the 20th century but the associated emissions of Hg and S from coal burning were significantly reduced since the 1990s. We studied dissolved (filtered) stream water mercury (Hg) and dissolved organic carbon (DOC) concentrations at five catchments with contrasting Hg and S deposition histories in the Bohemian part of the Czech Republic. The median filtered Hg concentrations of stream water samples collected in hydrological years 2012 and 2013 from the five sites varied by an order of magnitude from 1.3 to 18.0 ng L− 1. The Hg concentrations at individual catchments were strongly correlated with DOC concentrations r from 0.64 to 0.93 and with discharge r from 0.48 to 0.75. Annual export fluxes of filtered Hg from individual catchments ranged from 0.11 to 13.3 μg m− 2 yr− 1 and were highest at sites with the highest DOC export fluxes. However, the amount of Hg exported per unit DOC varied widely; the mean Hg/DOC ratio in stream water at the individual sites ranged from 0.28 to 0.90 ng mg− 1. The highest stream Hg/DOC ratios occurred at sites Pluhův Bor and Jezeří which both are in the heavily polluted Black Triangle area. Stream Hg/DOC was inversely related to mineral and total soil pool Hg/C across the five sites. We explain this pattern by greater soil Hg retention due to inhibition of soil organic matter decomposition at the sites with low stream Hg/DOC and/or by precipitation of a metacinnabar (HgS) phase. Thus mobilization of Hg into streams from forest soils likely depends on combined effects of organic matter decomposition dynamics and HgS-like phase precipitation, which were both affected by Hg and S deposition histories.

    Central Europe is generally not considered a drought-prone region, and the drought research and support is traditionally focused on the Mediterranean and southeastern part of the continent and drying trends there. However, Central Europe, including the Czech Republic, recently experienced a series of drought events with substantial impacts, especially on crop production. Because agriculture systems, and vegetation in general, have adapted to evenly distributed precipitation, the region is susceptible to even short-term droughts. The recent drought events may be the result of multi-decadal climate variability or a more general trend, with some studies showing a link to a more frequent occurrence of atmospheric circulation patterns that are conducive to drought. This study introduces an innovation to the standard methodological approaches in evaluating drought climatology by analyzing soil moisture conditions over more than fifty years. This approach relies on state-of-the art observed weather data and tested soil moisture model, and focuses on the dynamic simulation of soil moisture content with high temporal (daily) and spatial (500 m) resolution in a diverse landscape. Statistically significant trends of decreasing soil moisture content were found, notably during May and June between 1961 and 2012. In contrast, trends toward higher soil moisture content were noted during the October-March time period. When the periods of 2001-2012 and 1961-1980 were compared, the probability of drought between April and June was found to increase by 50%. This indicates a loading of the "climate dice" toward drier conditions. The probability of extreme drought events has been also found to increase. These results support the concerns about the potentially increased severity of drought events in Central Europe under projected climate change and has been submitted to International Journal of Climatology. The study was funded by project "Establishment of International Scientific Team

    Our study has been aimed at demonstrating the main role of viruses in the aetiology of acute gastroenteritis in children less than 5 years old and at pointing out the diagnostic potential of electron microscopy in the diagnosis of viral gastroenteritis. A prospective study was conducted to analyse the aetiology of diarrhoeal diseases in children less than 5 years of age admitted to the Department of Infectious Diseases between September 2006 and December 2008. All children were tested by faecal culture, latex agglutination and electron microscopy. A total of 832 children were included in the study. An aetiological agent was detected in 788 children (94.6 %). A bacterial aetiology was found in 22 (2.6 %) children and bacterial-viral co-infection was found in 146 (17.6 %) patients. The most frequent causative agents of gastroenteritis in children were viruses, which were detected in 620 (74.5 %) patients. The main causes of viral gastroenteritis were rotaviruses (detected in 410 children), followed by caliciviruses (42), coronaviruses (28), adenoviruses (19) and astroviruses (14). Dual viral infections were detected in 107 children, with rotavirus-calicivirus co-infection being the most common. Electron microscopy proved to be a more sensitive method in comparison with the latex agglutination test for the diagnosis of rotaviruses and adenoviruses. The major role of viruses in diarrhoeal diseases among children under 5 years of age in the Czech Republic has been confirmed. The diagnostic potential of electron microscopy, particularly in small outbreaks of gastroenteritis, was clearly shown.

  5. New technologies of waste disposal in Czech Republic, evoked by new laws

    Of the utmost importance for the conception of waste disposal in any country is the fact how rich the respective country is and how realistic its legislators are. The apparently ideal approach to solving this problem is that chosen by more affluent European countries where wastes are recycled, are charged with taxes and duties, and where wastes that necessitate to be disposed are handled similarly as the nuclear wastes. The benefits are evident. The amounts of wastes to be deposited are minimalized. The waste repositories can be sealed by using layers of clay, foil and clay, and during a period of 50 to 100 years, any communication of the repository with the ambient environments can be eliminated. The disadvantage of such waste repositories, if applied to most of wastes, are the high costs associated with their depositioning. The prices of products, which the costs of waste disposal are being reflected in, are thus increasing, and, for this reason, many of products are becoming unmarketable, even on the domestic market. These financial means are often spent for nothing because the service life of some protective elements being at present used for construction of waste repositories is limited in time (for example, the service life of isolating foil is 50 to 1 00 years). Waste disposal in the Czech Republic, particulary from power plants, is discussed.

  6. The polycyclic aromatic hydrocarbon concentrations in soils in the Region of Valasske Mezirici, the Czech Republic

    2009-01-01

    The polycyclic aromatic hydrocarbon (PAH) contamination of urban, agricultural and forest soil samples was investigated from samples obtained in the surroundings of Valasske Mezirici. Valasske Mezirici is a town located in the north-east mountainous part of the Czech Republic, where a coal tar refinery is situated. 16 PAHs listed in the US EPA were investigated. Organic oxidizable carbon was also observed in the forest soils. The PAH concentrations ranged from 0.86-10.84 (with one anomalous value of 35.14) and 7.66-79.39 mg/kg dm in the urban/agricultural and forest soils, respectively. While the PAH levels in the urban/agricultural soils are within the range typically found in industrialized areas, the forest soils showed elevated PAH concentrations compared to other forest soils in Western and Northern Europe. The PAH concentrations and their molecular distribution ratios were studied as functions of the sample location and the meteorological history. The soils from localities at higher altitudes above sea level have the highest PAH concentrations, and the PAH concentrations decrease with increasing distance from the town. PMID:20003407

    The activity concentration of (137)Cs in samples of coniferous forest humus collected across the territory of the Czech Republic in 1995 and 2005 was analysed, and it was found significantly correlated with the surface deposition caused by the Chernobyl accident. The effective (12.8 y) and environmental (22.3 y) half-lives of radiocaesium in humus were calculated and compared with those in spruce bark. The impact of important forest stand factors, that is, precipitation, content of organic matter, age of trees and pH, on the behaviour of (137)Cs in humus was studied. It was observed that humus samples with a higher proportion of organic matter, higher pH(H2O) and pH(CaCl2) contained higher amounts of (137)Cs. Conversely, with the age of trees, the activity concentration of (137)Cs in humus is decreasing. Higher precipitation and humus acidity decrease the reduction rate of the (137)Cs in humus. These stand factors increase bioavailability of (137)Cs in humus. The transfer and retention of available (137)Cs in biomass of organisms living in humus for a long time can satisfactorily explain the longer residence time of (137)Cs in humus affected by the studied factors.

    Context Research on the association between religiosity and fertility—and, particularly, on the effects of secularization on fertility desires and outcomes—has been concerned primarily with mechanisms that are fundamentally institutional and are embedded in formal religious structures. Supplementary explanations focused on noninstitutional dimensions of religiosity have never been tested. Methods Conventional ordinary least-squares regression was used to test the association between belief in God (i.e., a personal God or some sort of life force) and fertility desires among 2,251 women aged 18–45 in Slovenia and 951 women aged 15–44 in the Czech Republic who participated in the European Family and Fertility Survey in the mid-1990s. Results In both samples, substantial proportions of women either were nonbelievers or believed in God but were not institutionally religious. Belief in God was independently associated with fertility desires even in analyses controlling for self-reported religiosity. Women who believed in a personal God wanted approximately 0.2 more children, and those who believed in a life force wanted approximately 0.1 more children, than nonbelievers. Results were similar across several alternative measures of religiosity. Conclusions At least some of the connection between religiosity and fertility apparently is attributable to metaphysical beliefs. Future research on the effect of secularization on fertility decline should investigate the potentially distinct effects of different dimensions of religiosity. PMID:25682844

    To evaluate the accumulation of aluminium, cadmium, chromium, copper, lead, mercury, nickel, and zinc in crayfish and fish organ tissues, specimens from three drinking water reservoirs (Boskovice, Landštejn, and Nová Říše) and one contaminated site (Darkovské moře) in the Czech Republic were examined. Crayfish hepatopancreas was confirmed to be the primary accumulating site for the majority of metals (Cu > Zn > Ni > Cd > Cr), while Hg and Cr were concentrated in abdominal muscle, and Al and Pb were concentrated in gill. Metals found in Nová Říše specimens included Cu > Zn > Ni and those found in Boskovice included Zn > Hg > Cr. Cd concentrations were observed only in Landštejn specimens, while contaminated Darkovské moře specimens showed the highest levels of accumulation (Cu > Al > Zn > Pb). The majority of evaluated metals were found in higher concentrations in crayfish: Cu > Al > Zn > Ni > Cr > Cd > Pb, with Hg being the only metal accumulating higher in fish. Due to accumulation similarities of Al in crayfish and fish gill, differences of Hg in muscle, and features noted for the remaining metals in examined tissues, biomonitoring should incorporate both crayfish and fish to produce more relevant water quality surveys.

    Nickel is a metal that can be present in products containing hardened edible oils, possibly as leftover catalyst from the vegetable oil hardening process. Nickel may cause toxic effects including the promotion of cancer and contact allergy. In this work, nickel content was determined in hydrogenated vegetable fats and confectionery products, made with these fats, available on the Czech market using newly developed method combining microwave digestion and graphite furnace AAS. While concentrations of 0.086±0.014mg.kg(-1) or less were found in hydrogenated vegetable fats, the Ni content in confectionery products was significantly higher, varying between 0.742±0.066 and 3.141±0.217mg.kg(-1). Based on an average consumer basket, daily intake of nickel from vegetable fats is at least twice as low as intake from confectionery products. Based on results, the levels of nickel in neither vegetable fats nor confectionery products, do not represent a significant health risk.

    Individual monitoring of aircrew of airline operators registered in the Czech Republic has been performed since 1998. In this work, annual effective doses and annual collective effective doses of aircrew from occupational exposure in the period from 1998 to 2008 are presented, methods used for their evaluation and verification are described, and general trends observed in the data are discussed. Annual effective doses were calculated using the computer code CARI from flight schedules provided by airline operators and typical flight profiles. The method was verified via a comparison with (i) measurements using different types of detectors and (ii) calculations using the CARI and EPCARD codes with actual flight data. It was found that average annual effective doses in the period from 1998 to 2008 were in the range from 1.2 to 2.0 mSv and followed the trend of the solar cycle. Annual collective effective doses increased from 1.4 manSv in 1998 to 4.1 manSv in 2008 as the number of aircrew increased from 857 to 2158 during this period. Combined relative uncertainties (coverage factor ) of reported individual and collective effective doses were ∼ 25 %, which is well within the range given by the factor of 1.5. More work is needed to achieve a higher accuracy of this estimate.

    Children with preschool language difficulties are at high risk of literacy problems; however, the nature of the relationship between delayed language development and dyslexia is not understood. Three hundred eight Slovak and Czech children were recruited into three groups: family risk of dyslexia, speech/language difficulties and controls, and were assessed three times from kindergarten until Grade 1. There was a twofold increase in probability of reading problems in each risk group. Precursors of 'dyslexia' included difficulties in oral language and code-related skills (phoneme awareness, letter-knowledge and rapid automatized naming); poor performance in phonological memory and vocabulary was observed in both affected and unaffected high-risk peers. A two-group latent variable path model shows that early language skills predict code-related skills, which in turn predict literacy skills. Findings suggest that dyslexia in Slavic languages has its origins in early language deficits, and children who succumb to reading problems show impaired code-related skills before the onset of formal reading instruction.

    This paper focuses on the measurement and assessment of absorbed doses of radiation in caves of the Czech Republic, some of which exhibit high activity concentration of radon in air. Presented is an analysis and recommendations based on measurement results obtained in the underground caves over the past 12 y. The most important results for cave environments were as follows: integral radon monitoring using RAMARN detectors can provide more consistent results for calculating the effective dose; no major differences were shown in the average radon activity concentration during working time as opposed to non-working time; the unattached fraction of radioactive particles in air ranged from 0.03 to 0.6, with arithmetical average fp = 0.13; the direct dependence between equilibrium factor F and the size of the unattached fraction fp was described using the Log-Power expression ln(1/fp) = a*ln(1/F)(b); the calculated values for coefficients a and b were 1.85 and -1.096, respectively. The individual cave factor for each investigated underground area was calculated.

    The maar-diatreme volcanic structure in the vicinity of the village of Lomnice near the town of Bruntál (North Moravia, Czech Republic) has been investigated using a set of geophysical methods including ground magnetometry, gravimetry and electrical resistivity tomography. The structure was detected by an aerial magnetic survey in the second half of the 20th century. Since its discovery only limited information about this buried structure has been available. The coherence of the magnetic anomaly of 190 nT and Bouguer anomaly of -4.7 mGal indicates a volcanic origin of the structure. The funnel-shaped maar-diatreme structure is filled with lacustrine clay and colluvium of Car-boniferous greywacke, which forms the country rock. The surface diameter of the structure is about 600 m, the depth is more than 400 m. The spatial association with other volcanic centers in the surroundings of the town of Bruntál infers the relative dating of the Lomnice maar. The phreatic eruption and maar-diatreme formation could be an indirect conse-quence of effusive activity of the nearby Velký Roudný volcano. The Lomnice structure is the first Plio-Pleistocene maar-diatreme ever described in North Moravia and Silesia.

    A new steinernematid nematode, herein described as Steinernema poinari sp. n., was recovered by baiting soil samples with the last instar wax moth larvae Galleria mellonella in three localities of southwest Bohemia, Czech Republic. Morphological and molecular data confirmed this nematode as a new species which belongs to the affine/intermedium group. S. poinari sp. n. was characterized by male, female and infective juvenile morphological observations. Male spicules are robust with a pointed tip, SW% = 109 (98-123) and GS% = 70 (58-87). The tail terminus of the first generation have a papillated mucron, whereas in the second generation a short filamentous mucron sometimes develops. Females of the first generation have a moderately protruding vulva, postanal swelling absent or slightly developed. Second generation females have a long filamentous mucron on the tail tip. Infective juvenile have a body length of 768 µm, lateral field formula 2, 5, 6, 5, 2, 1, ratio D% of 46 (40-55), E% of 84 (76-95) and H% of 50 (43-56). The new species was characterized by sequences of ITS and D2D3 regions of ribosomal DNA. S. poinari sp. n. can also be separated from S. affine and S. intermedium by cross-breeding tests.

    2008-11-01

    The paper examines impacts on mortality of heat waves in 2003, the hottest summer on record in the Czech Republic, and compares them with previous similar events. While most summer heat waves over the period since 1986 were associated with significantly elevated mortality, this was not the case for three out of the four heat waves in 2003. The relatively weak mortality response was particularly noteworthy for the most severe heat wave which occurred in the first 10 days of August 2003 and resulted in enormous excess mortality in some western European countries. A mortality displacement effect and short-term adaptation to heat contributed to the reduced mortality impacts of the heat waves that followed after previous relatively warm periods. However, the decreased mortality response of the 2003 heat waves compared to previous heat waves in the 1990s is also likely to have arisen from positive health-care and other socio-economic changes in the post-communist central European region over the past decade, as well as a better public awareness of heat-related risks due to enhanced media coverage and regular biometeorological forecast and warnings.

    Our research focuses on the analysis of extreme high maximum air temperature events (EXHTEs) in the Czech Republic in the period 1961-2010, their climatological characteristics, and on the identification of synoptic-scale circulation conditions conductive to them. EXHTEs are detected using the Weather Extremity Index (WEI) combining return periods of daily maximum air temperature, duration of events, and the extent of the affected area. We selected 37 EXHTEs as non-overlapping periods with the highest WEI. Some long EXHTEs were divided into several shorter synoptically homogeneous episodes. Using the two-level divisive clustering of 700 hPa air temperature and wind field anomalies, we obtained four main variants of synoptic-scale circulation conditions. The most frequent variant associated with extreme episodes is characterized by a westerly flow connected with a high pressure ridge extending northeastward from North Africa over Central Europe or with an anticyclone centered over the Central Mediterranean. The most extreme episodes occurred during the variant characterized by an easterly flow between a high pressure area to the northeast and a low pressure area to the southeast.

    Media, and particularly TV media, have a great impact on the general public. In recent years, spatial patterns of information and the relevance of intangible geographies have become increasingly important. Gatekeeping plays a critical role in the selection of information that is transformed into media. Therefore, gatekeeping, through national media, also co-forms the generation of mental maps. In this paper, correspondence analysis (a statistical method) combined with cloud lines (a new visual analytics technique) is used to analyze how individual major regional events in one of the post-communist countries, the Czech Republic, penetrate into the media on a national scale. Although national news should minimize distortions about regions, this assumption has not been verified by our research. Impressions presented by the media of selected regions that were markedly influenced by one or several events in those regions demonstrate that gatekeepers, especially news reporters, functioned as a filter by selecting only a few specific, and in many cases, unusual events for dissemination.

    Evaluation of 108 cases when the pharmacist found a need to intervene into prescription verified the use of internationally employed system of classification of pharmaceutical interventions in the conditions of the Czech pharmacy of the basic type. The so-called dispensing care at the counter was provided by five participating pharmacists (out of seven working in the pharmacy) for a period of six months. The most frequently identified problems included: inappropriate use of medicaments--overdose, use at unsuitable time (28.7 %), a need to inform the patient (17.6 %), potentially ineffective therapy (12.9 %), drug interactions (7.4 %), suspected and potential undesirable effects of prescribed medicaments (7.4 %), and insufficient compliance (6.5 %). Solution of problems with medicaments was most frequently: a change in dosage (25.9 %), recommendation to consult the physician (24.1 %), and professional counselling on pharmacotherapy (23.1 %). The pharmacotherapeutic group identified as the one most frequently requiring a telephone consultation of the pharmacist and the physician was antibiotics, including antibacterial chemotherapeutic agents.

    The levels and profiles of 16 polybrominated diphenyl ethers congeners (PBDEs), three isomers of hexabromocyclododecane (HBCD) and other six "alternative" brominated flame retardants (BFRs) in dust collected in 25 Czech households and 27 car interiors were investigated. The Σ16 PBDEs contents varied widely with maximum concentrations reaching up to 5896 and 33728 μg/kg in house and car dust, respectively. The highest concentrations of PBDEs were observed for BDE 209, which was found almost in all samples and exceeded concentrations of other PBDEs even by one order of magnitude. The profile and levels of Penta-, Octa-, and DecaBDE obtained within this study were comparable to those presented in other studies worldwide and confirmed lower contamination of dust from Europe compared to North America. From the group of "alternative" BFRs, suitable for commercial applications as an alternative to banned PBDEs, mainly decabromodiphenyl ethane (DBDPE) and HBCD were detected in the concentration ranges <20-3567 and <0.3-950 μg/kg, respectively. γ-HBCD was dominating, forming up to 70% of ΣHBCD. Using the measured concentrations and estimates of dust ingestion rates it was estimated that toddlers had a higher exposure than adults for all compounds investigated.

    The present state of the environment in the Czech Republic is influenced by many factors and one of them is the quality of fuel used in energetic sources. The greatest share is created by coal, burned with a low capacity, big power station blocks without a significant effort to reduce the emission of pollutants. It is possible to use other provisions for improving the environment: (1) primary--changing the burning fuel, the minimization of pollutant formation resulting in a burning process, the reconstruction of a significant part of burning equipment, and others; (2) or secondary--trapping pollutants. Changing the fuel must be done, however, with minimization of outgoing pollutants. It should not burden surroundings with other undesirable influences and must provide the necessary output. One of the possibilities which is getting attention in the world today is the burning of biomasses. This solution itself has great investment cost (the necessity to build special burning equipment), but an attempt to burn suitable forms of biomass together with coal directly in the existing burning equipment has been discovered as a possible solution to this problem.

    The present state of the environment in the Czech Republic is influenced by many factors and one of them is the quality of fuel used in energetic sources. The greatest share is created by coal, burned with a low capacity, and besides big power station blocks without a significant effort to reduce the emission of pollutants. It is possible to use other provisions for improving the environment - primary - changing the burning fuel, the minimization of pollutant formation resulting in a burning process, the reconstruction of a significant part of burning equipment, and others - or secondary - trapping pollutants, that is cleaning the burning. Changing the fuel must be done, however, with minimization of outgoing pollutants. It should not burden surroundings with other undesirable influences and must provide the necessary output.

This solution itself has great investment cost (the necessity to build special burning equipment), but an attempt to burn suitable forms of biomass together with coal directly in the existing burning equipment has been discovered as a possible solution to this problem. The Department of Energetics has made a lot of experience and would like to present the information to the colleagues.

    The aim of this study was to compare knowledge about, confidence with, and attitudes towards epilepsy and affected people between groups of freshmen and senior teachers in training (preservice teachers) at the Faculty of Education in Pilsen, Czech Republic. Two hundred thirty-six freshmen and 138 seniors completed the 21-item Scale of Attitudes Towards People with Epilepsy (ATPE), an 18-item multiple-choice test measuring their knowledge about epilepsy, and a 5-item questionnaire focused on confidence with epilepsy in a school environment. We found that despite a higher level of knowledge about epilepsy among seniors (mean score of 9.6 points compared with 8.48 points for freshmen, p<0.001), attitudes towards epilepsy, and also confidence in how to manage children affected with this disease did not differ significantly. The presented findings suggest that epilepsy-related training of preservice teachers should be more effective especially with respect to their ability to resolve problems that may happen to children with epilepsy in a class.

    Polycyclic aromatic hydrocarbons (PAHs) are complex hazardous organic compounds that are introduced into the atmosphere as by-products of partial combustion processes. For common atmospheric conditions, the large molecular weight PAHs, such as benzo(a)pyrene (B[a]P), are found in the particulate phase and are believed to account for a considerable amount of the fine particulate matter toxic potential. Nonetheless, unlike meteorological variables and criteria pollutants, PAHs are very rarely monitored on a routine basis in most parts of the world. We present methodology for development and evaluation of a model for estimation of daily and monthly ambient B[a]P concentrations. The model utilizes a very large ambient B[a]P database from three sites in the Czech Republic. The difficulties faced when dealing with ambient PAH data are discussed. Model performance was evaluated by a complete internal-, external-, and temporal cross validations. The models reproduced very accurately monthly mean ambient B[a]P concentrations and provided acceptable daily mean B[a]P concentrations. Spatial extrapolations resulted in small deterioration of the models' performance. The temporal backward extrapolation revealed comparable errors to the spatial extrapolations in spite of the dramatic emissions reduction in the early years of the study period.

    We analyze the electric power load in the Czech Republic (CR) which exhibits a seasonality as well as other oscillations typical for European countries. Moreover, we detect the 1/f noise property of electrical power load with extra additional peaks that allows to separate it into a deterministic and stochastic part. We then focus on the analysis of the stochastic part using improved Multi-fractal Detrended Fluctuation Analysis method (MFDFA) to investigate power load datasets with a minute resolution. Extracting the noise part of the signal by using Fourier transform allows us to apply this method to obtain the fluctuation function and to estimate the generalized Hurst exponent together with the correlated Hurst exponent, its improvement for the non-Gaussian datasets. The results exhibit a strong presence of persistent behavior or strong anti-persistent behavior for the differences and the dataset is characterized by a non-Gaussian skewed distribution. There are also indications for the presence of the probability distribution that has heavier tail than the Gaussian distribution.

    Daphne shrubs with light green rings and mosaic on leaves contained flexuous filamentous virions (696 x 13 nm) and cylindrical inclusions typical of the subdivision III of Edwardson's classification for inclusions induced by members of the family Potyviridae. Decoration tests using antisera to 67 potyviruses revealed distant serological relations among chilli veinal mottle virus, Colombian datura virus, papaya ringspot virus, tobacco vein mottling virus and yam mosaic virus. The 3' terminal region of the virus genome was amplified by RT-PCR using primers specific for cloned and sequenced members of the family Potyviridae. The most similar sequences in the GenBank were those of isolates of wild potato mosaic virus (WPMV) and yam mild mosaic virus (YMMV), originating from Peru and Guadeloupe, respectively. The new sequence had 63.2% and 61.9% nucleotide identity to WPMV and YMMV in the coat protein gene. The results suggest that the Czech isolate from daphne should be regarded as a new member of the genus Potyvirus. The name daphne mosaic virus (DapMV) is suggested for this virus.

    We investigated the taxonomic status of a phenetically unique group of 25 Acinetobacter strains which were isolated from multiple soil and water samples collected in natural ecosystems in the Czech Republic. Based on the comparative sequence analyses of the rpoB, gyrB, and 16S rRNA genes, the strains formed a coherent and well separated branch within the genus Acinetobacter. The genomic uniqueness of the group at the species level was supported by the low average nucleotide identity values (≤77.37%) between the whole genome sequences of strain ANC 3994(T) (NCBI accession no. APOH00000000) and the representatives of the known Acinetobacter species. Moreover, all 25 strains created a tight cluster clearly separated from all hitherto described species based on whole-cell protein profiling by matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) and shared a unique combination of metabolic and physiological properties. The capacity to assimilate l-histidine and the inability to grow at 35°C differentiated them from their phenotypically closest neighbor, Acinetobacter johnsonii. We conclude that the 25 strains represent a novel Acinetobacter species, for which the name Acinetobacter bohemicus sp. nov. is proposed. The type strain of A. bohemicus is ANC 3994(T) (=CIP 110496(T)=CCUG 63842(T)=CCM 8462(T)).

  8. Declining impacts of hot spells on mortality in the Czech Republic: adaptation to climate change?

    Extreme temperature events have pronounced negative impacts on ecosystems and society, including human health effects. The study examines temporal changes in mortality associated with spells of large positive temperature anomalies (hot spells) in the population of the Czech Republic (central Europe) during 1986-2006. Declining trends in the mortality impacts are found in summer as well as in transition seasons, in spite of rising temperature trends (warming by 1.4 deg. C in summer over the 21-year period). The finding remains unchanged if possible confounding effects of within-season acclimatization to heat and the mortality displacement effect are taken into account. 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. The results suggest that climate change may have relatively little influence on heat-related deaths, since changes in other factors that influence 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 associated uncertainties in studies dealing with climate change projections of temperature-related mortality.

    Phasmarhabditis bonaquaense n. sp. is described and illustrated from the body of Malacolimax tenellus, from the locality of České Švýcary near the village of Dobrá Voda, the Czech Republic. Females are characterized by a body length of 2349 (1878-2626) µm and a cupola shaped tail with a long hyaline hair-like tail tip. Extremely prominent papilla-like phasmids present. Males 1829 (1414-2121) µm long. Peloderan bursa with nine pairs of rays (papillae), 1/1/1/2/1/3. One non-paired apparent papilla-like structure located near the ventral appendage anterior to the cloaca. Prominent papilla-like phasmids located close to the tail tip. Small subunit (18S), ITS, and D2-D3 expansion segments of the large subunit of ribosomal DNA were used to analyze the phylogenetic relationships of sequenced species in the genus Phasmarhabditis and other closely related species. Phasmarhabditis bonaquaense n. sp. varied from other related nematodes both in morphological characterizations and phylogenetic analysis. The life cycle of the newly described species is not well known but it is probably a facultative, mollusc-parasitic nematode able to survive permanently in the saprobic phase on decaying organic matter.

    To evaluate the accumulation of aluminium, cadmium, chromium, copper, lead, mercury, nickel, and zinc in crayfish and fish organ tissues, specimens from three drinking water reservoirs (Boskovice, Landštejn, and Nová Říše) and one contaminated site (Darkovské moře) in the Czech Republic were examined. Crayfish hepatopancreas was confirmed to be the primary accumulating site for the majority of metals (Cu > Zn > Ni > Cd > Cr), while Hg and Cr were concentrated in abdominal muscle, and Al and Pb were concentrated in gill. Metals found in Nová Říše specimens included Cu > Zn > Ni and those found in Boskovice included Zn > Hg > Cr. Cd concentrations were observed only in Landštejn specimens, while contaminated Darkovské moře specimens showed the highest levels of accumulation (Cu > Al > Zn > Pb). The majority of evaluated metals were found in higher concentrations in crayfish: Cu > Al > Zn > Ni > Cr > Cd > Pb, with Hg being the only metal accumulating higher in fish. Due to accumulation similarities of Al in crayfish and fish gill, differences of Hg in muscle, and features noted for the remaining metals in examined tissues, biomonitoring should incorporate both crayfish and fish to produce more relevant water quality surveys.

    Arsenic (As) occurs in atmospheric deposition both in soluble and insoluble forms, mainly bound to fine aerosol particles (less than 2.5 microm). Interception deposition (i.e. fog, dew and ice accretion) represents a specific type of atmospheric deposition, which has been much more contaminated with As than bulk deposition. This study compares the As amount and its binding forms in bulk and interception deposition in the winters of 1984-1986 and 2003-2005 in the Orlické hory mountains (Adlergebirge) near the Czech-Polish border; sampled and analysed by the same methodology. The As concentrations in ice accretions decreased 16 times over the twenty year period (from 50 microg L(-1) to 3 microg L(-1)), while the pH values increased by 0.8 units. As concentrations in snow decreased from 15 microg L(-1) in 1984-1986 to <2 microg L(-1) in 2003-2005. This decline mirrored the considerable decrease in industrial emissions in Central Europe. Higher acidity of interception deposition (about 1 pH unit) in comparison with the bulk deposition was observed in both sampling periods. The quantity of bulk deposition (snowfall) also influenced the As concentration in interception deposition. Dry periods resulted in higher As-amounts in interception deposition due to limited washing of atmospheric aerosol particles by wet deposition. The As concentration and stability in atmospheric deposition are important for the study of subsequent As-migration and/or accumulation in soil -- groundwater -- surface water.

    Non-steroidal anti-inflammatory drugs (NSAIDs) belong to most used pharmaceuticals in the human and veterinary medicine. The widespread consumption of NSAIDs has led to their ubiquitous occurrence in water environment including large river systems. In the present study, concentrations of the five most frequently used NSAIDs (ibuprofen, diclofenac, naproxen, ketoprofen and indomethacin) were determined in the watercourses of the river Elbe basin in Czech Republic. The presence of the pharmaceuticals was measured at 29 sampling sites including urban and rural areas, small creeks and main tributaries of the Elbe monthly from April to December of 2011. For the NSAIDs quantitation, the comprehensive analytical method combing pentafluorobenzyl bromide (PFBBr) derivatization with highly sensitive two-dimensional gas chromatography time-of-flight mass spectrometry (GCxGC-TOFMS) was developed. Although the content of all NSAIDs varied at the particular sampling points significantly, total amount of particular compounds was relatively stable during all monitored periods with only non-significant increase in the spring and autumnal months. Ibuprofen was found to be the most abundant drug with maximum concentration of 3210 ng/L, followed by naproxen, diclofenac and ketoprofen (1423.8 ng/L, 1080 ng/L and 929.8 ng/L, respectively). Indomethacin was found only at several sampling sites (maximum concentration of 69.3 ng/L). Concentrations of all compounds except ibuprofen were significantly higher at sampling sites with low flow rates (creeks), followed by the biggest watercourses.

    Characteristics of rainfall events in an ensemble of 23 regional climate model (RCM) simulations are evaluated against observed data in the Czech Republic for the period 1981-2000. Individual rainfall events are identified using the concept of minimum inter-event time (MIT) and only heavy events (15 % of events with the largest event depths) during the warm season (May-September) are considered. Inasmuch as an RCM grid box represents a spatial average, the effects of areal averaging of rainfall data on characteristics of events are investigated using the observed data. Rainfall events from the RCM simulations are then compared to those from the at-site and area-average observations. Simulated number of heavy events and seasonal total precipitation due to heavy events are on average represented relatively well despite the higher spatial variation compared to observations. RCM-simulated event depths are comparable to the area-average observations, while event durations are overestimated and other characteristics related to rainfall intensity are significantly underestimated. The differences between RCM-simulated and at-site observed rainfall event characteristics are in general dominated by the biases of the climate models rather than the areal-averaging effect. Most of the rainfall event characteristics in the majority of the RCM simulations show a similar altitude-dependence pattern as in the observed data. The number of heavy events and seasonal total precipitation due to heavy events increase with altitude, and this dependence is captured better by the RCM simulations with higher spatial resolution.

    We present the temporal trends and spatial changes of deposition of sulphur and nitrogen in Czech forests based on records from long-term monitoring. A statistically significant trend for sulphur was detected at most of the sites measuring for wet, dry, and total deposition fluxes and at many of these the trend was also present for the period after 2000. The spatial pattern of the changes in sulphur deposition flux between 1995 and 2011 shows the decrease over the entire forested area in a wide range of 18.1-0.2 g m(-2) year(-1) with the most pronounced improvement in formerly most impacted regions. Nitrogen still represents a considerable stress in many areas. The value of nitrogen deposition flux of 1 g m(-2) year(-1) is exceeded over a significant portion of the country. On an equivalent basis, the ion ratios of NO3(-)/SO4(2-) and NH4(+)/SO4(2-) in precipitation show significantly increasing trends in time similarly to those of pH.

    The Czech anatomist and physiologist of the 18th century, Jirí Procháska (1749-1820), ranks among the major figures of Czech cultural history. Due to historical circumstances, the works of Jirí Procháska were published mostly in Latin and only some in German. However, given that only two of his works have been translated into Czech and one of them also partially into English, the results of his extensive research activities are currently unavailable not only to the international scientific community, but also to the Czech scientific community. Although his research reflected the time in which he lived and thus has been re-evaluated by later researchers, his achievements undoubtedly belong to the major intellectual heritage of Czech science and certainly deserve attention as such. It is therefore our duty not only to remember the work and legacy of Jirí Procháska, which significantly influenced the development of our knowledge, but also to try to critically assess his contribution in terms of today. The article surveys the important biographical events of Jirí Procháska's life, taking into account the importance of his research and teaching.

    Data on concentrations of heavy metals (As, Cd, Cr, Cu, Fe, Hg, Mn, Ni, Pb, V and Zn) in moss collected on the lightly industrialized territory of Lithuania and on the highly industrialized territory of the Czech Republic in 1995, 2000 and 2005 is used to separate the background and anthropogenic contributions to heavy metal concentrations in moss. The distribution of the concentration logarithms allowed us to determine a background mode, and to estimate the background concentration of heavy metals from this mode. The method was then applied for an estimation of the contribution of local sources to the total pollution level in both countries. The average concentrations and the background modes of heavy metals in Lithuania and in the Czech Republic were very similar, except in the case of vanadium, where the background concentration was higher in Lithuania than in the Czech Republic. For most elements, the background concentration in moss had a decreasing tendency in Lithuania and in the Czech Republic between 1995 and 2005, though the concentration of Cu and Hg increased in Lithuania. The variability of chromium concentration in moss differed from the remaining investigated elements in the Czech Republic, and it was expressed as a bimodal lognormal distribution. This variability may be due to simultaneous contamination of moss by chromium from soil and from industrial sources of pollution.

    A mercury electrolysis chlor-alkali plant has been operating in Neratovice, the central Czech Republic since year 1948. We focused on the assessment of mercury contamination in the plant surroundings. To assess the contamination extent we sampled organic and mineral soils, bedrock, bark, needles and tree rings from several forest sites with variable distance from plant. The soils were predominately arenic cambisol and the vegetation cover composed of mixed to coniferous forests (majorly Pinus sylvestris). At all the sites, the highest concentrations occurred in the organic rich O horizons of the forest soils. The Hg concentrations increased from Oi horizon (up to 252 μg/kg) with fresh organic matter, through Oe horizons (up to 617 μg/kg) to the Oa horizons (up to 813 μg/kg) with relatively highly decomposed organic matter. The Hg concentrations in mineral soil were significantly lower in range from 3 to 44 μg/kg. Sandstone bedrock contained low Hg concentrations from 2.7 to 4.7 μg/kg. The difference between the high Hg in organic and low Hg in mineral horizons results from order of magnitude different content of soil organic matter. In the same time low Hg in mineral soil indicates low level of Hg migration down the soil profile. Apart from the simple comparison of Hg concentrations, insight into the patterns of soil Hg distribution can be gained by examining the stoichiometric ratios of Hg to C. Soil Hg/C should be greater in areas with greater atmospheric Hg deposition. O horizons of sites closer to plant up to 4.5 km exhibited elevated Hg/C ratios (2.0 - 2.2 μg/g) with respect to those at more distant sites (0.7 - 0.9 μg/g). Values of mineral soil Hg/C ratios varied irrespective to the distance from the plant. Organic soil Hg pool decreased from 13.6 mg/m2 in distance of 1.9 km from the plant to 2.6 mg/m2 in distance of 9 km. But the mineral soil Hg pool ranging from 7.6 to 12.3 mg/m2 exhibited no trend with distance. The polluted sites up to 2.5 km from

    The drying trends in the Czech Republic especially during May and June are of great concern as they influence the key part of growing season in the region. The fact that April-June period of 2001-2012 showed 50% increase of drought probability compared to 1961-1980 is alarming. In the same time the probability of extreme drought was found to be also rising significantly. This study tries to understand what has driven reported changes in the soil moisture especially during the warm half of the year. Therefore trends of global radiation, temperature, precipitation, relative humidity, wind speed, reference and actual evapotranspiration, snow cover but also start of key phenology phases were assessed and their relationship with the changes in the soil moisture analyzed. In addition measured pan-evaporation data as well as results of studies were used to assess reliability of the reported trends. We have found that increased global radiation and air temperature together with decreased relative humidity (all significant at 0.05) lead the increase of the reference evapotranspiration in all months of growing season. That was the case especially in April, May and August when over 80% of the territory showed statistically significant trends in reference evapotranspiration values. This finding was shown to be consistent with the observed pan evaporation (1968-2012) that was characterized by increasing trends especially during April-June period. These changes in combination with the earlier end of snow cover and earlier start of growing season (in some regions by up to 20 days) led to increased actual evapotranspiration at the start of growing season that tends to deplete the soil moisture earlier, leaving landscape more exposed to impacts of rainfall variability. These results support the concerns about the potentially increased severity of drought events in Central Europe. While the evaporative demand is clearly increasing, it is not matched by the similar increase of

    The FGD plant Tisovain the Czech republic is a retrofit downstream of a 100 MW lignite fired power plant. It was designed and built by L. and C. STEINMUELLER GmbH. Despite a narrow time schedule, the project was finished on time in December 1997. The major objectives of the applied limestone/gypsum process are: Minimum investment and operating costs; production and environmentally neutral disposal of a stabilized product containing the by-products fly ash, slag, gypsum and effluent. The first objective is achieved by the following new process arrangement: The flue gas is taken over from the boiler and fed directly into a wet scrubber for absorptive removal of the acid gases SO{sub 2}, HCl and HF. The cleaned flue gas is vented into the atmosphere without reheating by means of a wet stack which is arranged on top of the scrubber. By the described arrangement, a heat exchanger for cooling/heating of the flue gas is not required. No ductwork for connecting scrubber and stack is needed. Furthermore, the pressure drop across the FGD plant is minimized and allows the use of the already existing flue gas fans. Based on Steinmueller's experience with various limestone qualities, the powdered limestone supplied to the plant is milled once more on site. Thereby the reactivity of the limestone is enhanced resulting in low power consumption for the required plant performance. The second objective is achieved as follows: A part of the scrubbing liquid is continuously bled off as the underflow of a hydrocyclone station in order to remove the gypsum produced in the scrubber. A further dewatering of the gypsum does not take place. Instead, the effluent is mixed with fly ash and slag. As an additive, lime slaked with slag slurry is added. The resulting mixture is disposed of and compacted in the nearby opencast mine workings. It hardens in cement-like setting reactions to an environmentally safe stabilized product.

    The Czech Republic (CZ) had extremely high emissions and atmospheric deposition of pollutants in the second half of the 1980s. Since the beginning of the 1990s, moss, spruce bark and forest floor humus have been used as bioindicators of air quality. In the first half of the 1990s, seven larger areas were found to be affected by high atmospheric deposition loads. Six of these "hot spots" were caused by industrial pollution sources, mainly situated in coal basins in the NW and NE part of the country, and one large area in the SE was affected by increased deposition loads of eroded soil particles. After restructuring of industry in CZ, these hot spots were substantially reduced or even disappeared between 1995 and 2000. Since 2000, only two larger areas with slightly increased levels of industrial pollutant deposition and a larger area affected by soil dust have repeatedly been identified by biomonitoring. The distribution of lead isotope ratios in moss showed the main deposition zones around important emission sources. Very high SO2 emissions led to extreme acidity of spruce bark extracts (pH of about 2.3) at the end of the 1980s. The rate of increasing bark pH was strikingly similar to the rate of recovery of acid wet deposition measured at forest stations in CZ. By about 2005, when the median pH value in bark increased to about 3.2, the re-colonisation of trees by several epiphyte lichen species was observed throughout CZ. An increase in the accumulation of Chernobyl-derived (137)Cs in bark was detected at about ten sites affected by precipitation during the time when radioactive plumes crossed CZ (1986). Accumulated deposition loads in forest floor humus corresponded to the position of the moss and bark hot spots.

    The study examines the relationship between sudden changes in weather conditions in summer, represented by (1) sudden air temperature changes, (2) sudden atmospheric pressure changes, and (3) passages of strong atmospheric fronts; and variations in daily mortality in the population of the Czech Republic. The events are selected from data covering 1986-2005 and compared with the database of daily excess all-cause mortality for the whole population and persons aged 70 years and above. Relative deviations of mortality, i.e., ratios of the excess mortality to the expected number of deaths, were averaged over the selected events for days D-2 (2 days before a change) up to D+7 (7 days after), and their statistical significance was tested by means of the Monte Carlo method. We find that the periods around weather changes are associated with pronounced patterns in mortality: a significant increase in mortality is found after large temperature increases and on days of large pressure drops; a decrease in mortality (partly due to a harvesting effect) occurs after large temperature drops, pressure increases, and passages of strong cold fronts. The relationship to variations in excess mortality is better expressed for sudden air temperature/pressure changes than for passages of atmospheric fronts. The mortality effects are usually more pronounced in the age group 70 years and above. The impacts associated with large negative changes of pressure are statistically independent of the effects of temperature; the corresponding dummy variable is found to be a significant predictor in the ARIMA model for relative deviations of mortality. This suggests that sudden weather changes should be tested also in time series models for predicting excess mortality as they may enhance their performance.

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

    Between March 2012 and April 2014, we performed post-mortem parasitological examinations of 11 Eurasian beavers (Castor fiber Linnaeus, 1758) from the basins of four main rivers (Dyje, Labe, Morava, Vltava) in the Czech Republic. The cause of death of five adult animals was unknown, three adult animals died after being hit by cars, while one young and one adult as a result of serious injuries and one juvenile male drowned. The trematode Stichorchis subtriquetrus (Rudolphi, 1814) Lühe, 1909 was only found in the caecum body and caecum apex of nine beavers (82%), with no significant differences in parasite intensity among beavers. The highest number of trematodes (271) occurred in an adult female in July 2013; while a range of 1-57 individuals were found in other positive beavers. S. subtriquetrus size in both parts of the caecum was 11.0-17.0 × 5.5-8.0 mm (mean 14.3 × 6.9 mm). Results demonstrated that for the optimal detection of eggs, it was necessary to examine at least 10 g of faeces with a new modified method of sedimentation. The size range of 30 eggs was 157.1-182.5 × 99.3-109.8 μm (mean 168.0 × 104.4 μm). There were no differences in prevalence and seasonal occurrence of S. subtriquetrus between male and female beavers. We did not find any other intestinal endoparasites or tissue parasites (Sarcocystis spp., Trichinella spp.).

    Epidemiological evidence of lung cancer risk from radon is based mainly on studies of men employed underground in mines where exposures are relatively high in comparison to indoor exposure. Risk from residential radon can be estimated from occupational studies. Nevertheless, as such extrapolations depend on a number of assumptions, direct estimation of the risk is needed. The present study of lung cancer mortality was designed as a follow-up of a population (N = 12,004) in a radon prone area of the Czech Republic covering the period 1960-1999. Information on vital status and causes of death were obtained mostly from local authorities and from the national population registry. Exposure estimates were based on one year measurements of radon progeny in most houses of the study area (74%). Exposures outside the area (16%) were based on country radon mapping. Mean concentration of 509 Bq/m3 is higher than the country estimate by a factor of 5. By 1999, a total of 210 lung cancers were observed, somewhat more than the nationally expected number (O/E = 1.10) in comparison to generally low numbers corresponding to cancers other than lung (O/E = 0.81). The excess relative risk per standard radon concentration (100 Bq/m3) was 0.087 (90% CI: 0.017-0.208). This value is consistent with risk coefficients derived in other indoor studies. The present follow-up demonstrated that increased incidence of lung cancer depends linearly on exposure in terms of average radon concentration in the course of previous 5-34 years. Adjustment for smoking did not substantially change this estimate, although the risk coefficient for non-smokers (0.130) was higher in comparison to that for ever smokers (0.069), but not statistically different.

  5. Bohunician technology and thermoluminescence dating of the type locality of Brno-Bohunice (Czech Republic).

    Results of thermoluminescence (TL) dating of 11 heated flint artifacts from the 2002 excavation at Brno-Bohunice, Czech Republic, are presented. The samples are from the eponym locality for the Bohunician, an industrial type considered technologically transitional between Middle and Upper Paleolithic core reduction strategies. The Bohunician is the first early Upper Paleolithic technocomplex in the Middle Danube of Central Europe and, therefore, is implicated in several issues related to the origins of modern humans in Europe. The Bohunician provides an example of how one technological strategy combines crested blade initiation of a core with the surficial (almost Levalloisian) reduction of blanks as blades and points. As the Middle Danube lacks antecedents of the behavioral steps within this technology, several hypotheses of inter-regional cultural transmission, with and without hominin gene flow, could explain the appearance of the Bohunician. The elucidation of the temporal context of Bohunician assemblages is, therefore, a critical step in understanding the behavioral, and potentially biological, succession in this region. Radiocarbon age estimates from charcoal associated with Bohunician sites suggest a wide age range between 33 and 41 ka 14C BP, which is also observed for individual sites. TL dating of heated flint artifacts provides ages on the calendric time scale of an archeological event, the firing. The weighted mean of 48.2+/-1.9 ka BPTL for 11 heated flint samples from Brno-Bohunice provides the first non-radiocarbon data on archeological material from the Bohunician. The TL dating, in conjunction with the archeological and sedimentological analysis, allows the evaluation of the integrity of this new type-collection. The hypothetical possibility of the incorporation of Szeletian artifacts (i.e., leaf points) into the site formation processes can therefore be refuted.

    The Land Cover of the Czech landscape could change several times. Reconstructing Land Cover and especially greenery in the past is important for today's use of the landscape. Two periods were chosen to track changes in scattered greenery, the years 1953 and 2014. The source of information was an historical orthophotomap supplemented with a Military Topographic Map and an orthophotomap supplemented by terrain mapping. The software ArcMap and GuidosToolbox were used. The greenery was highlighted and manually converted to a vector format. The total area of the monitored territory is 2,190 hectares. In 1953, greenery took up 102 ha and 90 individual green areas were identified here. In 2014, greenery took up 222 ha and it was divided into 113 individual areas. In 1953 the perimeter of all green areas was 41,537 meters; in 2014 the perimeter of all green areas was 89,974 meters. There are two apparent trends here. The first is the simplification of shapes as a result of large-scale management; the second is the formation of a large length of linear greenery and small width with a large perimeter. The shape of the surface is linked to the area and perimeter. In 1953 this parameter was on average 1.87, and in 2014 the average value was 2.58. Comparing the results of the distance analysis of Label Objects using the GuidosToolbox software found that virtually all green areas were classified differently in 1953 and 2014. The results are completely different and further analysis makes no sense.

    Elevated mortality associated with high ambient temperatures in summer represents one of the main impacts of weather extremes on human society. Increases in cardiovascular mortality during heat waves have been reported in many European countries; much less is known about which particular cardiovascular disorders are most affected during heat waves, and whether similar patterns are found for morbidity (hospital admissions). Relatively less understood is also cold-related mortality and morbidity in winter, when the relationships between weather and human health are more complex, less direct, and confounded by other factors such as epidemics of influenza/acute respiratory infections. The present study analyses relationships between temperature extremes and cardiovascular morbidity and mortality. We make use of the datasets on hospital admissions and daily mortality in the population of the Czech Republic (about 10.3 million) over 1994-2009. The data have been standardized to remove the effects of the long-term trend and the seasonal and weekly cycles. Periods when the morbidity/mortality data were affected by epidemics of influenza and other acute respiratory infections have been removed from the analysis. We use analogous definitions for hot and cold spells based on quantiles of daily average temperature anomalies, which allows for a comparison of the findings for summer hot spells and winter cold spells. The main aims of the study are (i) to identify deviations of mortality and morbidity from the baseline associated with hot and cold spells, (ii) to compare the hot- and cold-spell effects for individual cardiovascular diseases (e.g. ischaemic heart disease I20-I25, cerebrovascular disease I60-I69, hypertension I10, aterosclerosis I70) and to identify those diagnoses that are most closely linked to temperature extremes, (iii) to identify population groups most vulnerable to temperature extremes, and (iv) to compare the links to temperature extremes for morbidity and

  8. Remote sensing of forest damage in the Czech Republic using hyperspectral methods

    Entcheva, Petya K.

    The current study assesses the potential of hyperspectral data for monitoring the initial stages of damage in Norway spruce forests characterized by subtle changes in foliar chlorophyll and chemistry. Both field and airborne high spectral resolution reflectance measurements were obtained for selected study sites in the Krusne hory, Czech Republic. High spectral resolution airborne canopy data and field foliar samples were acquired simultaneously in August 1998 for a total of 51 study sites within the Krusne hory. The sites were selected to represent a full range of damage conditions in even-aged Norway spruce (Picea abies (L.) Karst) stands located between 820--920m elevation. Reflectance, foliar pigments, nitrogen and chemical constituents were determined for first-, second- and third-year needles. A strong correlation to damage was established for the foliar chemistry. A significant increase in polar compounds (such as tannins, sugars and starch) and a reduced needle lignification occurs with increasing damage. Foliar chemical constituents appear to be effective indicators of long-term environmental conditions. The strong relationship between damage level and polar compounds suggests high potential for use of these constituents as bio-indicators of stress. Both field and airborne high spectral resolution data separate the initial forest damage classes. Based on field reflectance measurements for third-year needles, derivative indices from the red edge region were most strongly correlated to damage level, followed by indices ratioing damage-sensitive and damage-insensitive bands and a parameter describing the fit of an Inverted Gaussian curve. Red/red edge spectral data from the Airborne Solid State Array Spectrometer (ASAS) had the highest potential for separation of initial levels of damage, which corresponds with the region suggested as most sensitive to damage as seen in conducting the field reflectance measurements. Both optical and derivative indices

    2015-04-01

    In this paper, issues of agricultural drainage systems are introduced and discussed from the views of their former, current and future roles and functioning in the Czech Republic (CR). A methodologically disparate survey was done on thirty-nine model localities in CR with different intensity and state of land drainage systems, aimed at description of commonly occurred problems and possible adaptations of agricultural drainage as perceived by farmers, land owners, landscape managers or by protective water management. The survey was focused on technical state of drainage, fragmentation of land ownership within drained areas as well as on possible conflicts between agricultural and environmental interests in a landscape. Achieved results confirmed that there is obviously an increasing need to reassess some functions of prevailingly single-purpose agricultural drainage systems. Drainage intensity and detected unfavourable technical state of drainage systems as well as the risks connected with the anticipated climate change from the view of possible water scarcity claims for a complex solution. An array of adaptation options for agricultural drainage systems is presented, aiming at enhancement of water retention time and improvement of water quality. It encompasses additional flow-controlling measures on tiles or ditches, or facilities for making selected parts of a drainage system inoperable in order to retain or slow down the drainage runoff, to establish water accumulation zones and to enhance water self-cleaning processes. However, it was revealed that the question of landowner parcels fragmentation on drained land in CR would dramatically complicate design and realization of these measures. Presented solutions and findings are propounded with a respect to contemporary and future state policies and international strategies for sustainable agriculture, water management and environment.

    Loess and paleosol deposits, worldwide, have provided an important medium from which paleoclimatic conditions and paleoenvironments could be reconstructed. Within the field of environmental magnetism, the most fruitful data have been time series of various common magnetic parameters, such as, but not exclusively, bulk magnetic susceptibility and its frequency dependence, magnetic hysteresis derived parameters, and remanent magnetizations. Magnetic anisotropy data, capable of determined the orientation distribution of mineral particles within oriented bulk specimens, have proven to be a powerful tool even in non-lithified and poorly consolidated aeolian sediment. A 15 meter long loess and paleosol section at the Dolni Vestonice site in the Czech Republic (48°53'11.5''N 16°39'15.8''E) was investigated within the framework of a multi-disciplinary funded research project (ANR-08-BLAN-0227-CSD6). Here we present the interpretation of the anisotropy of magnetic susceptibility data set. Oriented specimens were collected from the 1 meter depth mark to the base of the section at a 5 or 10 cm depth sampling interval. Overall, 2 to 4 specimens were obtained at each sampling depth for a total of 632 specimens. The mean bulk magnetic susceptibility along the deposit is everywhere below 56 x 10-8 m3/kg and the degree of magnetic anisotropy (Pj) does not exceed 1.05. Intra-sampling depth reproducibility between specimens is good except in sand rich loess of the upper rapidly accumulating intervals. The magnetic anisotropy data, combined with field observations, optically stimulated luminescence chronology and other analytical data, reveal a fairly complete history of loess accumulation since the last interglacial. Nonetheless, the depositional environment was likely marked by hiatus, by erosional surfaces, and by post-depositional deformations driven by the local geomorphology and the regional tectonic setting.

    Hops represent an important natural source of bioactive polyphenols, particularly proanthocyanidins, which can contribute to prevention of several civilization diseases, owing to their antioxidant and radical scavenging activity. We have developed a high-throughput ultra-high-performance liquid chromatography time-of-flight mass spectrometry profiling method, which can be used for monitoring of bioactive proanthocyanidins in hops. The method was applied for analysis of hops of four Czech varieties (Saaz, Sladek, Preminat and Agnus) from the 2011 crop (9 localities, 11 samples) and the 2012 crop (24 localities, 40 samples). Hop samples were extracted by acetone and the analytes were separated on the Acquity UPLC BEH Shield RP18 column. Partial validation of the method revealed a satisfactory intra-day repeatability of the method for retention times (relative standard deviation within 1.39%) as well as areas under the peaks (within 9.89%). Experimental data were evaluated using principal component analysis and cluster analysis. Significant amounts of di-, tri- and tetramer proanthocyanidins consisting of (epi)catechin and (epi)gallocatechin were found in the hop samples. The dependence of the proantocyanidin composition on both the variety and the growing locality was observed. Specifically, the traditional Saaz variety contained more frequently oligomers formed by (epi)catechin units only, whereas the varieties Premiant and Agnus produced oligomers consisting of (epi)catechin as well as (epi)gallocatechin units. The relative abundance of proanthocyanidins in studied hop varieties from the two crops, 2011 and 2012, did correspond to each other. In the further perspective, the method may also be used for prediction of qualitative marks or authenticity verification of hops.

    Rivers and streams in the urban areas are losing natural environmental values. There is especially small watercourses issue, where there exists the lack of river management and interest of municipalities. The main used methods are based on the field research of river landscape, mapping and inventory of anthropogenic landforms and determination of Channel Capacity Coefficient (CCC). We establish the list of anthropogenic landforms, which we divide to the five categories - industrial, agrarian, urban, transport network, and water management structures. Values of the channel morphologic parameters - width of channel, width of riverbed, and the degree of countersink - are measured for Channel Capacity Coefficient calculation. Pattern of objects shrinking transverse profile and limiting the smooth flow are investigated beside the morphological features. Resulting from the application of these theoretical methods are several practical outputs. Firstly, we construct thematic grid cell monitoring maps (a) count of anthropogenic landforms in the floodplain; (b) weighted average of landform, whose weight was determined on the basis of their influence on the impact of floods. Secondly, we identify pattern distribution of the watercourses channel capacity in the selected study areas. Thirdly, we confirm existence of the urban stream syndrome which is characterized by consistently observed ecological degradation of brooks. The main symptoms of degradation are the altered channel morphology, occurrence of flashfloods, and the rate of ecological stability. Above mentioned characteristics were applied in two different catchments in the Czech Republic - the Leskava Brook and the Lacnovsky Brook. Both streams flow through the urban area in the diverse natural conditions and with various historical development. The Leskava Brook is situated in the southern part of Brno in the Southern Moravia, and the Lacnovsky Brook, lies in the northern part of Svitavy town on the border of Moravia

    2008-06-25

    In this study we evaluate the potential environmental and health impact of dairy cattle livestock and manure management in the Czech Republic. We present a new approach for national assessments of the environmental impact of an agricultural sector. Emission estimates are combined with a country-specific set of indicators to assess the environmental impact in nine regions with specific environmental characteristics. We estimate the contribution of emissions of ammonia (NH3) and nitrogen oxides (NO) to acidification and terrestrial eutrophication, nitrate (NO3) and phosphate (PO4) to aquatic eutrophication, nitrogen oxides (NO), particulate matter (PM10) and (PM2.5) to human toxicity and methane (CH4) and nitrous oxide (NO) to global warming. We present large regional differences in the environmental and health impact per unit of agricultural production. The regional acidifying, eutrophying and global warming impact of dairy cattle is calculated to be up to three times the national average, depending on the dairy cattle intensity. Aquatic eutrophication is found to be a problem in regions with relatively high eutrophying emissions per hectare of so-called nitrate vulnerable zones. Human toxicity problems caused by dairy cattle livestock and manure management are problematic in regions with a high population density in rural areas. The strength of our approach is the use of country-specific characterisation factors to assess the potential environmental and health impact of agriculture at the sub-national scale. We were able to analyse the potential environmental impact without explicit quantification of specific effects on humans and ecosystems. The results can be used to identify the most polluted areas as well as appropriate targets for emission reduction.

    Knowledge of contaminant behavior (e.g. its sorption onto soil particle, degradation etc.) is essential when assessing contaminant migration in soil and groundwater environment. This study was focused on evaluating sorption isotherms and half-lives for 7 pharmaceuticals (clarithromycin, trimethoprim, metoprolol, atenolol, clindamycin, carbamazepine, sulfamethoxazole) on 13 soils of different soil properties. Sorption of ionizable compounds was highly affected by soil pH. The sorption coefficient of sulfamethoxazole was negatively correlated to soil pH and thus positively related to hydrolytic acidity and exchangeable acidity. Sorption coefficients for clindamycin and clarithromycin were positively related to soil pH and thus negatively related to hydrolytic acidity and exchangeable acidity and positively related to base cation saturation. Sorption coefficients for the remaining pharmaceuticals (trimethoprim, metoprolol, atenolol, and carbamazepine) were also positively correlated with the base cation saturation and cation exchange capacity. Degradation rates in some degree reflected sorption of studied pharmaceuticals on soil particles and increased with decreasing sorption. The highest mobility in studied soils was observed for sulfamethoxazole, but this pharmaceutical was relatively quickly degraded. The second highest mobility was found for carbamazepine, which mostly did not noticeably degrade during our experiments. Thus this pharmaceutical has the highest potential to migrate in water environment. The lowest mobility was observed for clarithromycin. However, this pharmaceutical due to its stability may be retained in an environment for a long time.

    In recent years, the amount of radioactive materials seizures (captured radioactive materials) has been rising. It was above all due to newly installed detection facilities that were able to check metallic scrap during its collection in scrap yards or on the entrance to iron-mills, checking municipal waste upon entrance to municipal disposal sites, even incineration plants, or through checking vehicles going through the borders of the Czech Republic. Most cases bore a relationship to secondary raw materials or they were connected to the application of machines and installations made from contaminated metallic materials. However, in accordance to our experience, the number of cases of seizures of materials and devices containing radioactive sources used in the public domain was lower, but not negligible, in the municipal storage yards or incineration plants. Atomic Act No. 18/1997 Coll. will apply to everybody who provides activities leading to exposure, mandatory assurance as high radiation safety as risk of the endangering of life, personal health and environment is as low as reasonably achievable in according to social and economic aspects. Hence, attention on the examination of all cases of the radioactive material seizure based on detection facilities alarm or reasonably grounds suspicion arising from the other information is important. Therefore, a service carried out by group of workers who ensure assessment of captured radioactive materials and eventual retrieval of radioactive sources from the municipal waste has come into existence in the Nuclear Research Institute Rez plc. This service has covered also transport, storage, processing and disposal of found radioactive sources. This service has arisen especially for municipal disposal sites, but later on even other companies took advantage of this service like incineration plants, the State Office for Nuclear Safety, etc. Our experience in the field of ensuring assessment of captured radioactive materials

    Hailstorms are among the hydrometeorological extremes recognised in the historical past of the Czech Lands as grounds for tax relief if agricultural crops or material structures were damaged by them. The administrative process involved three levels (community, regional office, land office). The damage reports and taxation records for South Moravia (the southeastern parts of today's Czech Republic) were mainly stored in the Moravian Land Archives at Brno in estate accounts and collections of family archives. Data related to the date of a given hailstorm, its accompanying convective phenomena, the communities affected and the type of damage, as interpreted from taxation records, has created a database spanning the years 1650 to 1941 AD. A total of 766 records contain descriptions that cover 433 days upon which hailstorms did damage in South Moravia, as well as incidentally provide some additional information for the remainder of the Czech Lands and other parts of the Austro-Hungarian empire. The hailstorms detected concentrate to a large extent around the 1821-1850 period, which accounts for 44.4 % of all events. Although reported most frequently without other convective phenomena, they were often accompanied by torrential rain. The current contribution analyses the four most outstanding hailstorms in detail, those characterised by the highest number of estates and communities affected: 26 May 1830, 18 July 1832, 25 June 1844 and 20 June 1848. Uncertainties in hailstorm data, particularly with regard to their spatial and temporal heterogeneity, are discussed. Finally, the 1811-1850 period, with the highest number of hailstorm days, is compared with hailstorm patterns that derive from systematic meteorological observations in the 1961-2000 reference period. Damaging hailstorms disclosed by taxation data will be used to compile long-term hailstorm series for South Moravia (together with those derived from other documentary evidence and systematic meteorological

    The aim of this retrospective study was to determine the prevalence of lysosomal storage disorders (LSDs) in the Czech Republic. The data on cases diagnosed between 1975 and 2008 were collected and analyzed. The overall prevalence of LSDs in the Czech population (12.25 per 100,000) is comparable to that reported for the countries with well-established and advanced diagnostics of LSDs such as the Netherlands (14 per 100,000), Australia (12.9 per 100,000) and Italy (12.1 per 100,000). Relatively higher prevalence of LSDs was reported in the north of Portugal (25 per 100,000). Thirty-four different LSDs were diagnosed in a total of 478 individuals. Gaucher disease was the most frequent LSD with a birth prevalence of 1.13 per 100,000 births. The most frequent LSD groups were lipidoses, mucopolysaccharidoses, and neuronal ceroid lipofuscinoses, with combined prevalences of 5.0, 3.72, and 2.29 per 100,000 live births, respectively. Glycoproteinoses (0.57 per 100,000 live births), glycogenosis type II (0.37), and mucolipidoses (0.31) rarely occur in the Czech population, and a range of other LSDs have not been detected at all over the past three decades. Knowledge of the birth prevalence and carrier frequency of particular disorders is important in genetic counselling for calculation of the risk for the disorder in the other members of affected families. Earlier diagnosis of these disorders will permit timely intervention and may also result in lowering of the number of newborns with LSDs. PMID:20490927

    Two studies investigated the importance of phoneme awareness relative to other predictors in the development of reading and spelling among children learning a consistent orthography (Czech) and an inconsistent orthography (English). In Study 1, structural equation models revealed that Czech (n=107) and English (n=71) data were fitted well by the same predictors of reading and spelling. Phoneme awareness was a unique predictor in all models. In Study 2, Czech (n=40) and English (n=27) children with dyslexia showed similar deficits on phoneme awareness relative to their age- and spelling-matched control peers. Phoneme awareness appears to be a core component skill of alphabetic literacy, which is equally important for learners of consistent and inconsistent orthographies.

    Ground surface temperature histories were reconstructed from the temperature logs of eleven boreholes drilled in the Czech Republic. The study has identified several climate episodes during the past millennium, when the ground surface temperature oscillated with an amplitude of at least 2-3 K. Pronounced warming by up to 2 K characterized the beginning of the 20th century. The results seem to correlate well with climate reconstructions based on proxy data, and also with the long-term meteorological records. The paper represents the first part of a more extensive study aimed to propose a regional pattern of the past climate change derived from geothermal data in Central Europe.
