  10. The Conception Approach to the Traffic Control in Czech Cities - Examples from Prague

    NASA Astrophysics Data System (ADS)

    Tichý, Tomáš; Krajčír, Dušan

    Modern and economic development of contemporary towns is without question highly dependent upon traffic infrastructure progress. Automobile transport intensity is dramatically rising in large towns and other Czech and European cities. At the same time number of traffic congestions and accidents is increasing, standing times are becoming longer and ecological stress is also escalated. To solve this situation seems to be the most effective solution to design intelligent traffic light intersection control system, variable message signs, preference of public transportation, road line traffic control and next telematics subsystems. This control system and subsystems should improve permeability of traffic road network with a respect for all demands on recent trends of traffic development in towns and regions.

    2016-04-01

    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.

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

    NASA Astrophysics Data System (ADS)

    Urban, Aleš; Kyselý, Jan

    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.

    Opuka as a very fine-grained sedimentary rock deposited during Upper Cretaceous in relatively shallow (hemipelagic) marine conditions in the Bohemian Cretaceous Basin (Czech Republic) represents type of natural stone that has been widely exploited and used for construction from about 9th c. AD. Romanesque churches in Prague and central Bohemia are among the first preserved structures for which the opuka has been used. Question whether very local or more distant sources have been employed represents still unsolved matter. In the recent study, we focus on the detailed analysis of specimens of opuka taken from the Church of the Beheading of St. John the Baptist in Dolní Chabry (Prague). During the previous archaeological survey of the recent church (dated to 12th c. AD), remnants (basements constructed of opuka stone) of three older churches have recognized. The aim of recent material study is recognition of similarities or differences between opuka stones coming from these different construction phases and answering a question, whether material from a single source or from different localities has been employed. The study is based on the detailed petrographic examination using four sets of techniques: (1) microscopic observation (basic optical microscopy supplemented with the electron microscopy with microanalysis and X-ray elemental mapping), (2) X-ray diffraction of insoluble residue (composition of clay fraction and detection of some less organized silica forms), (3) chemical analysis and computation of modal composition by using normative minerals based on known mineralogical composition (input from microscopy and XRD), (4) study of physical properties, specifically by means of mercury porosimetry to quantify complex pore space of these rocks. Based on the results, three basic sets of specimens have been distinguished: (1) opuka stone with low content of carbonates (22-26 wt. %) and with higher content of kaolinite and illite (both WCI and PCI), (2) opuka stone

    In August 2002 the Czech Republic was struck by the largest flood in its history with the destruction of more than 1000 houses, tens of km of roads and dozens of bridges. The reconstruction of the country will take more than 2 years. The catastrophic flood was caused by two rainfall events following rapidly one after the other. Saturated basins and full river channels after the first rainstorm caused the highest water stages and discharges ever recorded in a number of river profiles in the country. In Prague two floods coincided, with run-off from the Vltava river cascade meeting the flood wave from the Berounka river. The floods in the Czech Republic and in Prague are still being assessed. The water level of this flood surpassed the flood marks from the last century by 70 - 100 cm. At the present time the value of the discharge in Prague is evaluated as 5200 {m^3 s-1}, whereas {Q100} is considered to be 3700 {m3s-1}. The Vltava in Prague is a trained river, protected by embankments ({Q50} and {Q20}) and protective dykes ({Q100} and {Q20}). In addition, a significant role in the flood protection of Prague was played by the manipulation of the dams of the Vltava river cascade, and by a new element - mobile walls protecting the historically valuable Old Town of Prague on the right bank of the Vltava. A conception for improving the flood protection of Prague was ready in the form of a design at the end of the {20th} century. It was ready for use in 2000, when the way in which it should be built was also checked. The calculation for the level of the mobile wall was based on mathematical modeling of the course of a hundred year flood in Prague. However, the mobile walls were constructed 50 cm higher than the calculated flood levels. During the flood, the water levels reached about 20 cm, and in some places only about 5 cm, below the top of the mobile walls, but the mobile walls were not overtopped. Mobile walls were not used on the left bank of the Prague city center

  1. 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

    challenging research domains in condensed form. The diversity of the different topics is especially impressive. 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.

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

    This study presents a flood frequency analysis for the Vltava River catchment using a major profile in Prague. The estimates of peak discharges for the pre-instrumental period of 1118-1824 based on documentary sources were carried out using different approaches. 187 flood peak discharges derived for the pre-instrumental period augmented 150 records for the instrumental period of 1825-2013. Flood selection was based on Q10 criteria. Six flood-rich periods in total were identified for 1118-2013. Results of this study correspond with similar studies published earlier for some central European catchments, except for the period around 1750. Presented results indicate that the territory of the present Czech Republic might have experienced extreme floods in the past, comparable - with regard to peak discharge (higher than or equal to Q10) and frequency - to the flood events recorded recently.

  13. Air quality of Prague: traffic as a main pollution source.

    2009-09-01

    Political and economical transition in the Central and Eastern Europe at the end of eighties significantly influenced all aspects of life as well as technological infrastructure. Collapse of outdated energy demanding industry and adoption of environmental legislation resulted in seeming improvements of urban environmental quality. Hand in hand with modernization the newly adopted regulations also helped to phase out low quality coal frequently used for domestic heating. However, at the same time, the number of vehicles registered in the city increased. The two processes interestingly acted as parallel but antagonistic forces. To interpret the trends in urban air quality of Prague, Czech capital, monthly averages of PM(10), SO(2), NO(2), NO, O(3) and CO concentrations from the national network of automated monitoring stations were analyzed together with long term trends in fuel consumption and number of vehicles registered in Prague within a period of 1992-2005. The results showed that concentrations of SO(2) (a pollutant strongly related to fossil fuel burning) dropped significantly during the period of concern. Similarly NO(X) and PM(10) concentrations decreased significantly in the first half of the nineties (as a result of solid fuel use drop), but remained rather stable or increased after 2000, presumably reflecting rapid increase of traffic density. In conclusion, infrastructural changes in early nineties had a strong positive effect on Prague air quality namely in the first half of the period studied, nevertheless, the current trend in concentrations of automotive exhaust related pollutants (such as PM(10), NO(X)) needs adoption of stricter measures.

    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.

  1. Calibration of historical geomagnetic observations from Prague-Klementinum

    NASA Astrophysics Data System (ADS)

    Hejda, Pavel

    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.

    One of the fundamental issues in European security is NATO expansion. This study examines the Czech Republic`s reasons for wanting to join NATO as well as its overall security policy in Europe. Because the Czech Republic is one of the premier candidates for NATO entry, understanding its motives and aspirations is important as a guide to promoting a better grasp of security issues in Central and Eastern Europe and to facilitating an improved understanding of the context in which NATO expansion will take place.

  7. 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.

  8. Charging systems for municipal solid waste: experience from the Czech Republic.

    2008-12-01

    The paper presents results of research into municipal waste treatment in the Czech Republic. Its special focus is on the impacts of various municipal solid waste charging systems on separating and recycling efforts of municipalities and households. The municipal solid waste charging systems are shortly described first, including the principles of the relevant Czech legislation. It shows that the Czech waste legislation provides space for implementing Pay-as-You-Throw (PAYT) models in the Czech Republic. The main results of representative surveys conducted by the authors within the EU PAYT project in 2003 in selected Czech municipalities and Prague households are shown. The survey confirmed that in municipalities that apply the PAYT charging system, citizens separate more waste and produce less residual waste. The survey data analysis has also shown which factors contributing to satisfactory waste separation are relevant and should be taken into the account when providing policy recommendations for introducing PAYT charging systems in other cities.

    Permanent Scatterers Interferometry SAR (PSInSAR) allows precise measurements of ground movements to be detected. This remote sensing technique assesses displacements along the satellite line of sight and detects vertical movements of targets on the Earth surface (called permanent scatterers). They are representing particularly by man-made objects (e.g. individual buildings) and by rock outcrops in a landscape. For area of Prague were processed 78 ERS1/2 SAR scenes for period from 1992 to 2005. Subsidence and uplift rates in the Prague area reach millimetres to centimetres per year. The PSInSAR analysis identifies primarily vertical movements of local significance, mostly subsiding of buildings and/or object complexes in the urban area. The second investigated Ostrava-Karviná area is heavily affected by long-term undermining activities. The PSInSAR data for this area relate to the 1995-2000 period (acquired by processing ERS1/2 48 SAR scenes). Displacements for the urban area of Ostrava town display subsiding effects, because of coal-mining decrease, while in the Karviná coal mining area they are still in a progress. Some areas located in the undermined region move down up to several decimetres per year. Detectable rate of vertical movement obtained by the PSInSAR application reaches at most 1.5 centimetres per year. Since in a few locations rates of movements are rather high, three scenes from 2007 by differential interferometry SAR were processed using the ALOS PALSAR approach to determine these intensive movements. The work was supported by the Targeted Research Programme of the Academy of Sciences of the Czech Republic (1QS300460551) and by Ministry of Education, Youth and Sport of the Czech Republic (LC506).

    Particles originating from the last major Eyjafjallajökull volcano eruption in April 2010 were subsequently found in settled dust samples collected in a suburban area of Prague, Czech Republic. These dust samples contained predominantly non-volcanic particulate matter of super-regional but mainly local origin. The highest proportion of the Eyjafjallajökull material recorded in the Prague daily dust samples reached 12% of the total lithic component mass. Volcanogenic particles, mostly glasses, were concentrated in particle size classes from 2.5 to 25 μm, but rare fragments of volcanic glasses up to 50 μm in diameter were also found. The most effective method for detection and identification of the volcanic ash particles were morpho-textural observations combined with energy dispersive and wavelength dispersive analysis of individual grains and X-ray powder diffraction. Because of the low percentage of volcanic ash particles in the total samples, the geochemical signal was rather weak although detectable in terms of selected trace elements and REE distributions. The mineralogy, particle size distributions, and geochemical compositions of the Prague samples were compared with reference materials sampled near the Eyjafjallajökull volcano.

    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. PMID:24423089

    2007-02-01

    Tornadoes have occurred in the territory of the Czech Republic throughout history. Although their frequency and intensity are not as high as in the USA, they can cause severe damage as well. That is why a systematic effort to document individual occurrences of this dangerous meteorological phenomenon as far as possible back into the past began in the 1990s. The aim of this investigation is to extend the first European catalogue of tornadoes originally published by Wegener [Wegener A., 1917. Wind-und Wasserhosen in Europe], by the addition of these cases from the Czech Republic. This paper adds further to Setvák, Šálek and Munzar [ Setvák M., Šálek M., Munzar J., 2003. Tornadoes within the Czech Republic—from medieval chronicles to the internet society. Atmos. Res. 67-68, 589-605], who reported the earliest documented tornado in the land of the Czech Republic which occurred in AD 1119 in Prague. In so doing, it presents recently discovered tornado cases from the 16th to the early 20th centuries, found in a variety of historical sources since the last ECSS conference held in Prague in 2002. In particular we will focus on the case from Jablonec nad Nisou (northern Bohemia) in 1925, which was probably the first case in the Czech Republic with accompanying photographic documentation of damage caused by a tornado.

    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

  3. The August 2002 flood in the Czech Republic

    The floods in August 2002 in the Czech Republic were caused by very intensive and large-scale rainfall that hit mainly the southern and western part of the country. There were two following rainfall events, the first on the {6th} and {7th} August and the second on the {11th} and {12th} August. The total sum of areal rainfall was 150 to 200 mm; in mountain areas more than 250 mm and in some localities even more than 300 mm. Such large-scale rainfall amounts are extraordinary for Czech conditions. The first wave of rainfall caused floods in the majority of rivers. There were 10 to 20 year floods, exceptionally 100-year (and more) floods on rivers in the southern and western part of the country. When the second wave of rainfall followed the first one, rivers were already full of water and soils were saturated: therefore the runoff response was rapid and massive. Water levels in all rivers rose very quickly again and they reached their historical maxima in many places. Peak discharges in most streams reached or exceeded a 100-year flood and in some rivers a 1000-year flood. The capital of the Czech Republic, Prague, is situated at the confluence of two rivers, the Moldau and the Berounka (left hand tributary of the Moldau). The flow in the Moldau River can be partly controlled by operation of many reservoirs in the upstream reaches of the river (the Moldau cascade), the flow in Berounka is not influenced. During the first flood event the major part of the wave was retained by the reservoirs and the discharge in Prague was reduced. During the second event the inflow into the reservoir system was so high that reservoirs were filled before the peak occurred. The peak flow from the Berounka River coincided with the maximum outflow from the Moldau. As a consequence, on 14th August the peak discharge in Prague was about 5200 {m3/s} (the long-term mean discharge is 150 {m3/s}) and is preliminarily judged to be a 500-year flood. The influence of the Moldau cascade on the

    Four centuries ago in 1610, the Kepler family were living in their last place of residence in Prague, in a house in a courtyard off Karlova Street (Karlova ulice), very close to the east end of Charles Bridge (Karluv most). The house is No.188, U Francouzske koruny (French Crown House), and has a passage through to Anenska Street. Kepler spent 12 years in the city, publishing his most important works including Astronomia Nova.

  5. Geophysical research in the Czech Republic

    Čermák, Vladimir

    General interest in Earth studies has a long tradition in the Czech Republic that dates back to the German physician, Georg Agricola, a pioneer in scientific classifications of minerals collected in North Bohemia's Ore Mountains during the early 16th century. Astronomy flourished during the rule of Hapsburg Emperor Rudolph II (1552-1612). Modern geophysics developed in the middle of the 18th century from systematic meteorological observations and continued in the 19th century with H. Benndorfs seismological experiment in the mining town of Pribram.In 1920, the State Geophysical Institute was created, with Vaclav Laska as its first director. The institute's research activities concentrated on seismology and geomagnetism. In 1945, the Chair of Geophysics was established at the Charles University in Prague, reflecting the increasing interest in geophysical studies. The Czechoslovak Academy of Sciences was founded in 1952, the same year that the first Conference of Czechoslovak Geophysicists passed the resolution that an institute of geophysics should be reestablished within the new academy as the coordinating and leading institution of basic geophysical research.

    2007-11-02

    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.

    As we commemorate the 30th anniversary of the Campylobacter, Helicobacter, and Related Organisms (CHRO) workshops with this special Frontiers edition, we look back upon three decades of research and provide some highlights from the 16th International CHRO meeting. Although Theodor Escherich himself provided drawings of campylobacters back in the 1880s, Campylobacter jejuni was not identified until the 1950s. Helicobacter pylori was first described to be the causative agent of stomach ulcers at a CHRO meeting by Barry Marshall and Robin Warren—who later received the Nobel Prize for their findings that bacteria could cause diseases previously believed to be caused by human factors. Now, several genome sequences for campylobacters, helicobacters, and related organisms are available and we have moved into an era examining the intersection between host microbial ecology and pathogen infection. Both pioneers and new investigators in the CHRO research field continue to obtain “unexpected results” demonstrating that campylobacters and helicobacters do not follow classic paradigms of other well-characterized gastrointestinal pathogens and we are learning that there is a plethora of interesting related organisms beyond C. jejuni and H. pylori. This review summarizes recent discoveries in CHRO research and the exciting directions ahead. PMID:22919612

    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.

  14. What Mathematics Is Hidden Behind the Astronomical Clock of Prague?

    NASA Astrophysics Data System (ADS)

    Krizek, M.; Solcova, A.; Somer, L.

    2006-08-01

    The mathematical model of the astronomical clock of Prague was developed by the professor of Prague University, Joannes Andreae, called Sindel. It was realized by Mikulas from Kadan around 1410. Over the centuries its construction has been renovated several times. The ingenuity of clockmakers of that time can be demonstrated by the following construction. The astronomical clock of Prague contains a large gear with 24 slots at increasing distances along its circumference. This arrangement allows for a periodic repetition of 1-24 strokes of the bell each day. There is also a small auxiliary gear whose circumference is divided by 6 slots into segments of arc lengths 1, 2, 3, 4, 3, 2. These numbers form a period which repeats after each revolution and their sum is s = 15. At the beginning of every hour a catch rises, both gears start to revolve and the bell chimes. The gears stop when the catch simultaneously falls back into the slots on both gears. The bell strikes 1 + 2 + ... + 24 = 300 times every day. Since this number is divisible by s = 15, the small gear is always at the same position at the beginning of each day. The large gear has 120 interior teeth which drop into a pin gear with 6 little horizontal bars that surround the centre of the small gear. The large gear revolves one time per day and therefore, the small gear revolves 20 times per day with approximately 4 times greater circumferential speed, since its circumference is 5 times smaller. This makes the regulation of strokes sufficiently precise despite the wearing out of the slots on the large gear. When the small gear revolves it generates by means of its slots a periodic sequence whose particular sums correspond to the number of strokes of the bell at each hour: 1, 2, 3, 4, 5 = 3 + 2, 6 = 1 + 2 + 3, 7 = 4 + 3, 8 = 2 + 1 + 2 + 3, 9 = 4 + 3 + 2, ... We show that we could continue in this way until infinity. However, not all periodic sequences have such a nice summation property. The astronomical clock of

    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

    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. PMID:25130638

    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.

  2. Comparison of SSC and epidemiological approaches to evaluating links between heat stress and mortality in Prague, Czech Republic

    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

    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.

    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.

    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

    Highway bridge in the southern part of Prague, Czech republic, is the longest bridge in the Czech republic and it is architectonically unique in Europe. It was built above the valley with confluence of two big rivers, Vltava and Berounka, in an area of frequent floods. On top, there is a five-lane highway with an important, circle-shape crossroad, and both ends of the bridge end up in a tunnel. During construction, steel was partially replaced by concrete in comparison to the plan, and first cracks arose just after opening of the bridge in September 2010, and are progressively getting bigger. We try to monitor this bridge using the InSAR technique with 22 TerraSAR-X scenes, acquired in the Staring Spotlight mode with a resolution of approximately 0.3 meters during June 2014 - February 2015 (11 days interval).

    How do different parts of a basin contribute to discharge? Case study Rokytka Brook, Šumava Mts., Czech Republic Lukáš Vlček, Jan Kocum, Bohumír Janský, Luděk Šefrna Charles University in Prague, Faculty of Science, Prague, Czech Republic Runoff formation is a very important issue within a flood protection and drought prevention. To solve this topic a lot of parameters, which affect the outflow, need to be known. Especially it is necessary to find out which part of a catchment contributes mostly to discharge during flood events or during drought periods. Optimal conditions for such a research are provided by our study in Šumava Mts., where a number of former floods has been created. In near future this area can play role within the water storage enhancement in SW Czech Republic during drought periods. Central part of Šumava Mts. is covered with peat bogs and other peaty soil types which are mostly supplied by rain water. This study takes place in the small catchment (1 km²) in Šumava Mts. It is created by 2 main slopes with different vegetation and soil coverage. First slope is covered by well-developed peat bog where 3 springs were found, the second slope is covered by dead spruce forest and soil type of entic Podzol, where one spring was found. Each specific part of the catchment was mapped and equipped by devices such as water level probe or tensiometers. Spring discharges and outflow have been observed. For consecutive analyses water silica, stable isotopes and temperature observations have been carried out as well. Results of this research should help to better understand the runoff process taking place in the core zone of Šumava Mts. Moreover it should improve a flood forecasting and the knowledge about retention ability of Czech mountains.

    The eruption of Mount Tambora in Indonesia in 1815 was one of the most powerful of its kind in recorded history. This contribution addresses climatic responses to it, the post-eruption weather, and its impacts on human life in the Czech Lands. The climatic effects are evaluated in terms of air temperature and precipitation on the basis of long-term homogenised series from the Prague-Klementinum and Brno meteorological stations, and mean Czech series in the short term (1810-1820) and long term (1800-2010). This analysis is complemented by other climatic and environmental data derived from rich documentary evidence. Czech documentary sources make no direct mention of the Tambora eruption, neither do they relate any particular weather phenomena to it, but they record an extremely wet summer for 1815 and an extremely cold summer for 1816 (the "Year Without a Summer") that contributed to bad grain harvests and widespread grain price increases in 1817. Possible reasons for the cold summers in the first decade of the 19th century reflected in the contemporary press included comets, sunspot activity, long-term cooling and finally - as late as 1817 - earthquakes with volcanic eruptions.

    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. PMID:26980521

    The variability of aerosol chemical composition and the impact of the origin of respective air masses were studied in high time resolution for selected periods of high and low levels of aerosol burden at a suburban station in Prague-Suchdol, Czech Republic in summer and winter. Ambient aerosol measurements were performed using the compact-Time of Flight-Aerosol Mass Spectrometer (c-ToF-AMS) and variations in concentration of the main species are discussed. The average mass concentrations for the main species were (summer; winter): organic matter (4.2 μg/m3; 8.4 μg/m3), SO42- (2.0 μg/m3; 4.4 μg/m3), NH4+ (1.2 μg/m3; 2.8 μg/m3), NO3- (0.8 μg/m3; 5.4 μg/m3) and Cl- (0.1 μg/m3; 0.23 μg/m3). We found an inverse relationship between non-refractory submicron particulate matter (NR-PM1) levels and the boundary layer height, mainly in winter. Furthermore, levels of pollution were influenced by the air mass origin, where cleaner maritime air masses resulted in lower aerosol levels compared to those of continental origin. Analysis of the diurnal variation of NR-PM1 showed minimum concentrations in the afternoon caused by dilution as a result of an increase in the boundary layer height. Most maximum concentrations of the main species occurred in the morning or night except sulphate which had a midday maximum, probably due to downdraft from upper boundary layer air and photochemical formation in the afternoon.

  17. Assessment and treatment of aphasia in czech.

    PubMed

    Lehečková, Helena

    2012-01-01

    Intervention approaches to aphasia differ in different countries. The aim of this paper is to give an overview of the situation in the Czech Republic. The following topics are summarized: (1) Czech logopedics in aphasiology; (2) the assessment of aphasia; (3) the treatment of aphasia; (4) Czech aphasiologic material; (5) the qualification of clinical logopedists, and (6) regulations of aphasiologic care. Czech is a very intricate language, both phonetically and grammatically. The prevalence of consonants appearing in long sequences (a whole sentence can be constructed purely of consonants) makes it difficult to pronounce. The strong inflecting character with hundreds of grammatical forms for each inflected word makes it difficult to use correct morphology and syntax. These facts make Czech a real challenge both for aphasics and logopedists. An overview of aphasia tests and treatment methods used in the Czech Republic, as well as conditions of logopedic care are given. The paper will allow comparison with the situation in other countries. PMID:23108445

    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.

    The Demirjian methods to determine dental age are based on analysis of orthopantograms. The dental age estimation is based on establishing the tooth development stages. The purpose of this study was to assess the accuracy of estimation of dental age by Demirjian in the use of all of his four methods. 505 Czech healthy boys and girls aged 3 to 18 years were examined radiographically at the Department of Stomatology, Second Faculty of Medicine, Charles University in Prague. It was mentioned the factors of underlying diseases influence the accuracy of the dental age estimation. For statistical evaluation, descriptive statistics was used to compare deviations of the mean values of chronological and dental age in each age group. The resulting difference between dental age and chronological age is not significant in both genders only when using both Demirjian 7-teeth methods of 1973 and 1976. Therefore these may be most appropriately used for forensic age estimation. There are shown standard deviation differences in different countries. Demirjian's original 7-teeth method from 1973 and Demirjian's revised 4-teeth method from 1976 appear to be the best methods for calculating the dental age of healthy Czech children of both genders.

    Thin foils, 0.5-50 μm in thickness, have been irradiated in vacuum at Prague Asterix Laser System in Prague using 1015-16 W cm-2 laser intensity, 1315 nm wavelength, 300 ps pulse duration and different focal positions. Produced plasmas from metals and polymers films have been monitored in the forward and backward directions. Ion and electron accelerations have been investigated by using Thomson parabola spectrometer, x-ray streak camera, ion collectors and SiC semiconductor detectors, the latter employed in time-of-flight configuration. Ion acceleration up to about 3 MeV per charge state was measured in the forward direction. Ion and electron emissions were detected at different angles as a function of the irradiation conditions.

    Not only the public debate about science but even the way scientists conceive their own work is to some extent determined by cultural images. In the case of synthetic biology, literary figures like the Golem of Prague and its successors, such as Frankenstein's monster, seem to suggest themselves. This article reconstructs some cognitive structures underlying the surface of metaphorical thinking and shows how talking about synthetic biology as similar to Golem-making obscures important ontological, pragmatic, and ethical differences.

    The territory of the Czech Republic was contaminated as a result of the breakdown in the Chernobyl nuclear power plant in 1986. The Czech population received low doses of ionising radiation which, though it could not cause a deterministic impact, could have had stochastic effects expressed in the years following the accident. Twenty years after the accident is a long enough time to assess its stochastic effects, primarily tumours and genetic impairment. The moderate amount of radioactive fallout received by the Czech population in 1986 increased thyroid cancer in the following years; on the other hand, no obvious genetic impact was found.

    2012-01-01

    This article examines whether housing tenure and regional differences in housing affordability have an impact on labour mobility. This relationship is important for understanding the sources of structural unemployment and impediments to economic growth. Using two sample surveys from the Czech Republic, this research reveals that at the individual level housing tenure is the most powerful factor determining willingness to change residence for employment reasons. A time-series regression analysis reveals that the impact of housing affordability on observed interregional migration patterns is relatively weak and that this effect is concentrated among the highly educated seeking employment in the capital, Prague. These results demonstrate that housing tenure has a significant impact on labour migration plans in case of unemployment and that the dynamic impact of regional differences in housing affordability on labour mobility is concentrated within the most highly skilled segment of the labour force.

    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.

    Whole blood selenium, copper, zinc and manganese concentrations of 197 institutionalized senior citizens (46 males, 151 females) aged 61-100 years (mean age 83.6 years) were determined using atomic absorption spectrometry and inductively coupled plasma mass spectrometry from two localities in the Czech Republic (Prague and Teplice) from 2009 through 2011. Geometric means (GM) of whole blood selenium (B-Se), copper (B-Cu), zinc (B-Zn) and manganese (B-Mn) levels were 74.0 μg/l, 941.0 μg/l, 5898.0 μg/l and 10.9 μg/l, respectively. Gender-related differences were found with significantly higher B-Cu levels in women and significantly higher B-Zn levels in men. The percentage of seniors with B-Se levels lower than 56 μg/l (which is equivalent to the critical value of 45 μg/l of Se in serum (S-Se)) was 8.6%. A negative correlation between age and B-Se levels was found. B-Zn positively correlated with serum albumin and prealbumin whereas a negative correlation between age and B-Zn was observed. Seniors with diabetes mellitus and atherosclerosis had higher B-Cu and B-Mn levels, respectively, than those without these diagnoses. The elderly from Prague had significantly higher B-Mn concentrations than those from Teplice. We found no evidence of serious essential elements deficiencies or excesses in the seniors who participated in this study. PMID:23245729

    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. PMID:23588853

    Linkages between lunar synodic cycle and select types of meteorological parameters have been suggested in previous studies. In important papers it was demonstrated that extreme precipitation events occur more frequently on the third to fifth day after syzygies. The effect is sometimes called Bowen's signal and similar lunar or semi-lunar modulation was later found also in ozone concentrations, sunshine, thunderstorm frequencies and in global temperatures observed by polar orbiting satellites. In our earlier papers we tried to analyse the possibility that the effect is transient in relation to solar activity. We confirmed the long-term quasi-periodical nearly-parallel changes in expression of lunar signal in 14 century-long daily precipitation series across Europe. The prevailing periods seemed to be similar to 22-year Hale solar magnetic cycle but there was no clear evidence and other similar celestial cycles could not be excluded. A unique set of uninterrupted daily precipitation data from Prague-Klementinum since 1804, published by the Czech Hydrometeorological Institute, was available. In this study we also made use of a related dataset of daily mean cloudiness that dates back as far as 1775. The cloud cover has been observed in a subjective way but we think its reliability is relatively good. In the case of precipitation we also examined the series of days with daily amount exceeding 10 mm. The data were divided into epochs of synodic months and superposed for 5 or 11 years with a step of one year. We get six sets of mean 29-day synodic signals containing 198-204 records for precipitation and 227-233 records for cloudiness. The temporal occurrence of lunar variation was defined as correlation coefficient ψ between semi-lunar cosine function (period 4π/29.53), emulating the Bowen's signal, and the mean signals. The coefficients ψ drawn against time created quasi-periodical charts ranging over more than two centuries. The impression of the ever

    Wind erosion risk strongly depends on soil surface conditions. Aridity or dryness of the climate in the Czech Republic is a typical property for Southern Moravia and Central Bohemia. The study aims to map and assess qualitatively the areas vulnerable to wind erosion using available data and intelligible methodology. The evaluation is based on the number of days when at least once a day dry condition of bare soil surface was recorded. Daily data of soil surface state from 70 climatological stations to 500 m altitude from 1981 to 2010 are used. First, soil conditions from 1st March to 30th April and from 1st September to 31st October were evaluated. Evaluation of erosion risk in May is presented separately in the second phase, because only thermophilous crops (late-sowing crops) can be affected in that time. The results show that mainly in the South and Southeast Moravia, there are areas where up to 60 days with dry soil surface in the spring and autumn occurred. Occurrence of such conditions may represent potential risk of wind erosion for arable soils and therefore potential risk for sown crops and loss of fertile soil surface which is irreplaceable for agricultural activities. The results are applicable for preparation of a concept of wind erosion control measures in the threatened regions.

    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

    This study tested the hypothesis that being born of an unwanted pregnancy is a risk factor for poor mental health in adulthood. Self-report and objective data were collected at ages 28 to 31 and 32 to 35 years in a cohort of nearly 200 "unwanted" subjects born after their mothers had been twice denied an abortion for the same pregnancy. The same data were collected in a sociodemographically matched control cohort of "accepted" subjects whose mothers had not requested an abortion, and from siblings of both the unwanted subjects and the accepted control subjects. Logistic regression analyses conducted with several indicators of poor mental health in adulthood as dependent variables brought partial support for the hypothesis. Specifically, unwanted subjects became psychiatric patients (especially psychiatric inpatients) more frequently than their siblings and the accepted controls. Criminality, alcohol-related disorders, and heavy smoking were not associated with unwanted pregnancy. PMID:12409858

    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.

    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.

  1. Lead isotope ratios in tree bark pockets: an indicator of past air pollution in the Czech Republic.

    Tree bark pockets were collected at four sites in the Czech Republic with differing levels of lead (Pb) pollution. The samples, spanning 1923-2005, were separated from beech (Fagus sylvatica) and spruce (Picea abies). Elevated Pb content (0.1-42.4 microg g(-1)) reflected air pollution in the city of Prague. The lowest Pb content (0.3-2.6 microg g(-1)) was found at the Kosetice EMEP "background pollution" site. Changes in (206)Pb/(207)Pb and (208)Pb/(206)Pb isotope ratios were in agreement with operation times of the Czech main anthropogenic Pb sources. Shortly after the Second World War, the (206)Pb/(207)Pb isotope ratio in bark pockets decreased from 1.17 to 1.14 and the (208)Pb/(206)Pb isotope ratio increased from 2.12 to 2.16. Two dominant emission sources responsible for these changes, lignite and leaded petrol combustion, contributed to the shifts in Pb isotope ratios. Low-radiogenic petrol Pb ((206)Pb/(207)Pb of 1.11) lead to lower (206)Pb/(207)Pb in bark pockets over time. High-radiogenic lignite-derived Pb ((206)Pb/(207)Pb of 1.18 to 1.19) was detected in areas affected by coal combustion rather than by traffic. PMID:18597820

    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. PMID:19722578

  3. Twenty year development of occupational diseases in the Czech Republic: medical and geographical aspects.

    2014-12-01

    The study analysed occupational diseases in the Czech Republic from the viewpoint of occupational medicine and medical geography. It used a dataset consisting of 32,646 cases of occupational diseases reported during the period of 1994-2013. The descriptive part of the study analysed occupational diseases according to their spatial distribution, occurrence in different branches of economic activities, employees' gender, and according to chapters of the List of occupational diseases. The incidence of occupational diseases showed an overall decreasing trend, which can be related to several factors--transformation of the national economy (shift from heavy industry to manufacturing industry and services), an improvement in access to occupational healthcare services, increased responsibility of employers for safe working conditions, but also a concealment of health problems by employees for fear of losing job. An exception to the decreasing trend is the automotive industry, in which the upward trend in occupational diseases occurrence was noted. The analytical part of the study focused on the relation between unemployment and occupational diseases incidence rates in different regions of the Czech Republic. In most regions, a statistically significant inverse association was shown between the rate of unemployment and occupational disease incidence. The situation is described in more detail for the Moravia-Silesia and Ustí nad Labem Regions and the Capital City of Prague, wherein a statistically significant inverse association was shown between the rate of unemployment and occupational disease incidence. The theory of marginal utility can explain the phenomenon. To certain degree of health problems, employees tend to prefer employment stability, especially if the unemployment is on rise in their region. On the other hand, if losing their job, they often try to claim benefits connected with occupational diseases. PMID:25622483

    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.

    Thin black surface layers or black coloured gypsum crusts can be observed on stones of many buildings and sculptures around the world. The black weathered stone and mortar surface from selected sections of the Prague Castle were studied by microscopic methods, GC/MS and pyrolysis-GC/MS analysis. Microscopically, we found an authigenic gypsum formation with an outer layer of an admixture of fine grains of quartz, clay minerals, thermally altered clay minerals, fly ash, and carbonaceous particles of natural and anthropogenic origin particularly chars, cokes, soots. Noncarbonate C content ranged between 0.8% and 4.3%. Phtalates dominated in extracts from the samples and benzonitrile had the greatest abundance in the pyrolysis products. The identified organic particles and compounds are known to result from human activities. PMID:21855962

    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. PMID:21250499

    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.

    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.

Both NPPs were built to Soviet design and according to Soviet regulations and standards but most of equipment for primary circuits was supplied by home manufactures. The objective for the Czech LBB programme is to prove the LBB status of the primary piping systems of these NPPs and the LBB concept is a part of strategy to meet western style safety standards. The reason for the Czech LBB project is a lack of some standard safety facilities, too. For both Dukovany and Temolin NPPs a full LBB analysis should be carried out.

    2011-06-01

    The Czech Hydrometeorological Institute (CHMI) has utilized lightning data from the Central European Lightning Detection Network (CELDN) since 1999. The CELDN primarily focuses on the detection of cloud-to-ground (CG) lightning but intra-cloud (IC) lightning detection is also available. Lightning detection is used by the CHMI forecasters as an additional source to radar and satellite data for nowcasting of severe storms. Lightning data are also quantitatively used in automatic nowcasting applications. The quality of lightning data can be evaluated using their climatological characteristics. Climatological characteristics are also useful for defining decision thresholds that are valuable for human forecasters as well as for automatic nowcasting applications. The seven-year period from 2002 to 2008, which had relatively even-quality lightning data, was used to calculate the spatial and temporal distributions of lightning. The monthly number of CG strokes varies depending on the season. The highest number of CG strokes occurs during summer, with more than 20 days of at least five detected CG strokes on the Czech Republic territory in June and July. The least number of CG stokes occurs in winter, with less than three days per month having at least five detected CG stokes. The mean diurnal distribution of CG strokes peaks between 1500 and 1600 UTC and reaches a minimum between 0500 and 0800 UTC. The average spatial distribution of CG strokes shows sharp local maxima corresponding with the locations of the TV broadcast towers. The average spatial distribution of CG flash density, calculated on a 20 × 20 km grid, shows the maximum (3.23 flashes km - 2 year - 1 ) in the western part of Czech Republic and the minimum (0.92 flashes km - 2 year - 1 ) in the south-southeast of the Czech Republic. In addition, lightning characteristics related to the identified convective cells, such as distribution of the lightning stroke rates or relation to the radar derived by Vertically

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

    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).

    Based on hitherto unknown layouts and documents from the Prague archives, this paper reviews the evolution of the health care system in the capital of Bohemia. From the high Middle Ages to the Enlightenment, the town's history as well as changing political and religious tendencies provide a unique background for the development of different types of institutions for the care of the poor and sick. The first charitable foundations of the sovereigns and the archbishops were soon followed by the semi-monasterial infirmaries of the Hospitallers. Leprosoria and other shelters for the contagious deserve special attention. After the counter-reformation, the newly built hospitals of orders like the Brothers of Saint John of God and the Sisters of Saint Elizabeth played an important role. From the architectural point of view, the baroque hospitals built by Kilian Ignaz Dientzenhofer belong to the most impressive examples of hospital architecture in Europe. Finally, the medical reforms of Emperor Joseph II. led to a series of completely new institutions, which can be regarded as the beginning of modern medicine im Bohemia. It was especially intended to describe exactly the site and the architectonic appearance of the preserved buildings. Thus, the medical historian can contribute to the care and preservation of these medical monuments. PMID:7631381

    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.

    Background Brominated flame retardants (BFRs)—polybrominated diphenyl ethers (PBDEs) and hexabromocyclododecane (HBCD)—belong to the group of relatively “new” environmental contaminants. The occurrence of these compounds in the Czech aquatic ecosystem was for the first time documented within the 3-year monitoring study initiated in 2001. In 2002–2003 HBCD and the major PBDE congeners (28, 47, 49, 66, 85, 99, 100, 153, 154, and 183) were found in 136 freshwater fish samples collected from several sampling sites located at three Czech rivers (Vltava, Elbe, Tichá Orlice). Chub (Leuciscus cephalus), barbel (Barbus barbus), bream (Abramis brama), perch (Perca fluviatilis), and trout (Salmo trutta), representing the most common fish species, were examined by gas chromatography coupled with negative chemical ionization mass spectrometry. Results The presence of PBDE congeners and HBCD was detected in all analyzed samples (limits of detection for target analyts ranged from 0.015 to 0.1 ng/g lipid weight). Without exception the dominating congener was BDE-47. The most pronounced extent of fish contamination was found in the Vltava river at Klecany, downstream from the industrial agglomeration of Prague. As for fish species, the highest concentrations of PBDEs (sum of congeners) were measured in benthic species, represented by bream and barbel, up to 19.6 ng/g wet weight and 16.5 ng/g wet weight, respectively. The lowest accumulation occurred in predator fish (perch and trout). The highest levels of HBCD were detected in barbel from Srnojedy on the Elbe River (15.6 ng/g wet weight), downstream.

    Mackuľak, Tomáš; Birošová, Lucia; Grabic, Roman; Škubák, Jaroslav; Bodík, Igor

    2015-09-01

    The aim of this study was to compare estimation of nicotine use in Slovakia (SR) and the Czech Republic (CR) based on cotinine analysis in wastewater from seven selected wastewater treatment plants (WWTPs) with conventional estimation based on tobacco product sales. Urinary bio-markers of nicotine use were analyzed by liquid chromatography coupled with tandem mass spectrometry (LC-MS/MS). The study was performed concurrently at all the WWTPs (from 11 to 18 March 2014). Representative 24 h composite samples were analyzed with on line SPE/LC-MS/MS method. Based on the average residence time of wastewater in the sewers and the average time in the sampling device, specific correction coefficients were designed to improve estimation of nicotine consumption. Nicotine ingestion level was back-calculated and expressed as mass of pure drug consumed per day and per 1000 inhabitants for selected cities of both countries (mean, 2.2 g for Piešťany and 8.0 g for Nitra, respectively). Consequently, the cigarette consumption results were recalculated for each country separately and compared with the data of both national statistical offices (2362 cigarettes/year/person--SR and 2088 cigarettes/year/person--CR). Our results highly correspond to the data of national statistical offices (up to 99.9% in SR and to 96% in CR). The average amount of money invested in cigarette sales was estimated in the capitals of both countries. It is about 1 million EUR/day for Prague and about 0.3 million EUR/day for Bratislava. The calculation of nicotine consumption, utilizing a specific correction coefficient, is the correct way to obtain more accurate data in drug studies of this kind, thus allowing a better drug abuse assessment.

    2014-07-01

    Since the early 1990s, the Czech Republic has been one of the countries that carry out a radon programme on its territory, with the aim of protecting people from unnecessary long-term exposure in their homes. Since that time, many achievements have been registered, and many unexpected difficulties have cropped up. This may be the right moment to take some time out to analyse the state of the programme and to determine the direction for its future development. An extended SWOT analysis can serve as a useful tool for this purpose. Originally, SWOT analyses were used exclusively by for-profit organisations aiming to evaluate their perspectives, develop strategies and make plans in order to achieve their objectives. More recently, it has been used in a wide range of decision-making situations when a desired end-state is to be defined. Here, an extended SWOT analysis is used to formulate possible beneficial strategies for advancing anti-radon policy in the Czech Republic. PMID:24729595

    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.

  20. Previously expressed wishes in the Czech republic--a missed chance of the Czech legislator.

    PubMed

    Peterková, Helena

    2013-12-01

    By ratification of the Convention on Human Rights and Biomedicine, previously expressed wishes as a completely new institute have been, via Article 9, implemented in the Czech legal system. With no history of practical experience with previously expressed wishes, and after more than 6 years of legislative work on the new Act on Healthcare Service, a unique provision was enacted which is actually not meant to serve as an instrument enabling withdrawal of the mechanical support of vital functions. In this paper, the great paradox of the Czech legal provision on previously expressed wishes is to be discussed and critically analyzed in order to explain the seriousness of the consequences of initial misunderstanding of the purposes and context of previously expressed wishes.

    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.

  4. The issue of surrogacy in Czech law.

    PubMed

    Lojková, Jana

    2012-03-01

    Surrogacy is thought to be one of the most controversial methods of assisted reproduction. It involves cases where a commissioning couple asks a surrogate mother to give birth to a child that will be conceived from their egg and sperm because the woman from the commissioning couple is not able to bear the child to full term herself. They conclude an agreement where the surrogate mother binds herself to terminate all her parental rights to the child immediately after the child's birth and to delegate them together with the child to the commissioning couple. Ethical dilemmas concerning the issue of surrogacy together with all the possibilities of today's globalised world that enable infertile couples to find surrogate mothers abroad in case the legal regulations of their country put a ban on it create a space for a legislator to try to find a solution that will avoid all the risks and highlight a number of positives on the other hand. A Czech legislator is currently trying to find this solution and even though there are few children demonstrably born to surrogate mothers in the Czech Republic, the whole process of surrogacy still proceeds in a legal vacuum at the moment. We can only find the legal definition of a mother of a child as a woman that gives him or her birth and a provision of law that makes all the legal acts that evade the law void. Some practical consequences of this situation will be described in the text together with possibilities and the inspiration that comes from foreign legal regulations and cases. PMID:22908742

    The 2nd Annual European League Against Rheumatism (EULAR) Congress, held in Prague, 13–16 June 2001, was an impressive event with a record turnout of 8300 delegates. It offered a large variety of first-class state of the art lectures by some 180 invited worldwide speakers. Several new and ongoing therapeutic developments were discussed. The aim to attract the young scientific community was only partly achieved, and the dependence on industry posed some problems. The organization, however, was a big improvement compared with the previous congress in this series. The number of submitted abstracts was relatively low (1200) compared with the number of delegates. Accommodation of satellite symposia and organization of poster sessions remain problem areas of this meeting. The Annual EULAR Congress emerges as one of the two most important annual congresses of rheumatology, the other being the American College of Rheumatology meeting.

    In this study, we attempt to target both the urokinase plasminogen activator and the mitogen-activated protein kinase pathway in acute myeloid leukemia (AML) cell lines and primary AML blasts using PrAgU2/LF, a urokinase-activated anthrax lethal toxin. PrAgU2/LF was cytotoxic to five out of nine AML cell lines. Cytotoxicity of PrAgU2/LF appeared to be nonapoptotic and was associated with MAPK activation and urokinase activity because all the PrAgU2/LF-sensitive cell lines showed both uPAR expression and high levels of MEK1/2 phosphorylation. Inhibition of uPAR or desensitization of cells to MEK1/2 inhibition blocked toxicity of PrAgU2/LF, indicating requirement for both uPAR expression and MAPK activation for activity. PrAgU2/LF was also cytotoxic to primary blasts from AML patients, with blasts from four out of five patients showing a cytotoxic response to PrAgU2/LF. Cytotoxicity of primary AML blasts was also dependent on uPAR expression and phos-MEK1/2 levels. CD34+ bone marrow blasts and peripheral blood mononuclear cells lacked uPAR expression and were resistant to PrAgU2/LF, demonstrating the lack of toxicity to normal hematological cells and, therefore, the tumor selectivity of this approach. Dose escalation in mice revealed that the maximal tolerated dose of PrAgU2/LF is at least 5.7-fold higher than that of the wild-type anthrax lethal toxin, PrAg/LF, further demonstrating the increased safety of this molecule. We have shown, in this study, that PrAgU2/LF is a novel, dual-specific molecule for the selective targeting of AML. PMID:26500025

    2015-09-01

    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. PMID:26448298

    The presentation highlights main results of the InterDrought project (2013-2015), which includes several Czech universities and research institutes, and also shows overview of multidisciplinary scientific monograph on drought. The basic data sources consisting of instrumental, documentary, tree-ring and satellite data are presented. Selected drought indices (SPI, SPEI, Z-index and PDSI) calculated from homogenised Czech temperature and precipitation series are used to describe spatial and temporal variability of droughts in the Czech Lands for the 1804-2010 period including selection of drought extreme episodes and their detail description with respect to meteorological and synoptic patterns and impacts as well. Analysis of droughts prior 1804 is based on documentary data and oak tree-ring widths used for compilation of 500-year Czech drought chronology. The occurrence of extreme droughts is further analysed with respect to sea-level pressure patterns in the Atlantic-European area, climate forcings and changes in land-use. Examples of agricultural and hydrological droughts are mentioned. High resolution soil moisture models are used to estimate drought trends in last five decades as well as estimate future development of droughts in the Czech Republic. Overview represented by this paper will be complemented by several individual detail studies of other InterDrought Team members.

    Background Approximately 30%–60% of adults diagnosed with bipolar disorder (BD) report onset between the ages 15 and 19 years; however, a correct diagnosis is often delayed by several years. Therefore, investigations of the early features of BD are important for adequately understanding the prodromal stages of the illness. Methods A complete review of the medical records of 46 children and adolescents who were hospitalized for BD at two psychiatric teaching centers in Prague, Czech Republic was performed. Frequency of BD in all inpatients, age of symptom onset, phenomenology of mood episodes, lifetime psychiatric comorbidity, differences between very-early-onset (<13 years of age) and early-onset patients (13–18 years), and differences between the offspring of parents with and without BD were analyzed. Results The sample represents 0.83% of the total number of inpatients (n=5,483) admitted during the study period at both centers. BD often started with depression (56%), followed by hypomania (24%) and mixed episodes (20%). The average age during the first mood episode was 14.9 years (14.6 years for depression and 15.6 years for hypomania). Seven children (15%) experienced their first mood episode before age 13 years (very early onset). Traumatic events, first-degree relatives with mood disorders, and attention deficit hyperactivity disorder were significantly more frequent in the very-early-onset group vs the early-onset group (13–18 years) (P≤0.05). The offspring of bipolar parents were significantly younger at the onset of the first mood episode (13.2 vs 15.4 years; P=0.02) and when experiencing the first mania compared to the offspring of non-BD parents (14.3 vs 15.9 years; P=0.03). Anxiety disorders, substance abuse, specific learning disabilities, and attention deficit hyperactivity disorder were the most frequent lifetime comorbid conditions. Conclusion Clinicians must be aware of the potential for childhood BD onset in patients who suffer from

    + 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.

    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.

  14. The state of psychiatry in the Czech Republic.

    Höschl, Cyril; Winkler, Petr; Pěč, Ondřej

    2012-08-01

    This overview of Czech psychiatry begins with a brief review of its history; outlines its social, political and economic determinants and then describes the field itself. Both epidemiological and service-related information are discussed, together with the issues for mental health personnel, education and research. The heavy burden of communist history pervades most areas and must be taken into account in the specific characteristics that influence both the current situation and future prospects of Czech psychiatry. This consideration is essential for orientation in the field and to understand Czech particularities. The greatest challenges, however, originate from the fundamental changes that are going on in the world today. These challenges reach beyond national boundaries and include such phenomena as globalization, migration, ageing population, growing burden of mental ill health, the still prevailing stigma towards psychiatry, and the psychological roots and consequences of current financial and societal crises.

    1995-12-01

    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.

    Description of an Urban Heat Island (UHI) using the difference in air temperature is one of the world's most studied characteristics. If, however, one wants to express how the temperature is perceived by humans, one must consider the overall effect of air temperature, wind speed, air humidity and radiation flows, which is expressed using temperature bioclimatological indexes. One of them is the so-called physiological equivalent temperature (PET), which is used for quantification of the overall effect of meteorological parameters combined with human energetic balance and which is perceived by humans. The RayMan (Matzarakis et al 2007, 2010) microscale models in the city of Prague were used to simulate biometeorological conditions describing the effect on humans using PET. This study was funded by project "Building up a multidisciplinary scientific team focused on drought" No. CZ.1.07/2.3.00/20.0248. Michal Žák would like to thank the project "UHI - Development and application of mitigation and adaptation strategies and measures for counteracting the global Urban Heat Islands phenomenon" (number 3CE292P3). This project is implemented through the CENTRAL EUROPE Programme co-financed by the ERDF.

  1. The contribution of ambient sources to particulate pollution in spaces and trains of the Prague underground transport system

    NASA Astrophysics Data System (ADS)

    Braniš, Martin

    During a fixed-route including (i) surface walk on streets, (ii) underground spaces (corridors, vestibules and platforms) and (iii) underground trains of the Prague Metro Rail System (PMRS) a fast response portable photometer was used to measure concentrations of PM 10 (particulate matter <10 μm). On the basis of more than 100 monitored trips the PMRS may be characterised as more polluted than the streets above. On average, the highest PM 10 concentration was recorded inside the Metro trains (113.7 and 1.44), the second highest in the underground spaces of stations (102.7 and 1.29), followed by outdoor environment (74.3 and 0.85), expressed in μg m -3 and in dimensionless relative normalised units, respectively. In spite of the statistically significant difference (p<0.001) between ambient and underground PM 10 levels recorded by the photometer, the ambient concentrations were tightly associated with those from the underground spaces (r2=0.820) as well as from the Metro trains (r2=0.774). The correlation between concentrations from both underground microenvironments was even higher (r2=0.964) indicating a common source of aerosol inside the PMRS. Since also reasonable correlation was found between fixed site monitors (FSM) and both ambient and underground photometer PM 10 levels a strong influence of surface traffic-related particulate pollution on the underground air quality is suggested.

  2. Effects of sudden air pressure changes on hospital admissions for cardiovascular diseases in Prague, 1994-2009

    Plavcová, Eva; Kyselý, Jan

    2014-08-01

    Sudden weather changes have long been thought to be associated with negative impacts on human health, but relatively few studies have attempted to quantify these relationships. We use large 6-h changes in atmospheric pressure as a proxy for sudden weather changes and evaluate their association with hospital admissions for cardiovascular diseases (CVD). Winter and summer seasons and positive and negative pressure changes are analysed separately, using data for the city of Prague (population 1.2 million) over a 16-year period (1994-2009). We found that sudden pressure drops in winter are associated with significant rise in hospital admissions. Increased CVD morbidity was observed neither for pressure drops in summer nor pressure increases in any season. Analysis of synoptic weather maps shows that large pressure drops in winter are associated with strong zonal flow and rapidly moving low-pressure systems with centres over northern Europe and atmospheric fronts affecting western and central Europe. Analysis of links between passages of strong atmospheric fronts and hospital admissions, however, shows that the links disappear if weather changes are characterised by frontal passages. Sudden pressure drops in winter are associated also with significant excess CVD mortality. As climate models project strengthening of zonal circulation in winter and increased frequency of windstorms, the negative effects of such weather phenomena and their possible changes in a warmer climate of the twenty-first century need to be better understood, particularly as their importance in inducing excess morbidity and mortality in winter may increase compared to cold spells.

  12. Nuclear medicine training and practice in the Czech Republic.

    PubMed

    Kamínek, Milan; Koranda, Pavel

    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. PMID:24867257

  14. [Development and current utility of infobases in Czech cancer care].

    PubMed

    2014-01-01

    Evaluation of the quality and effectiveness of health care is an integral part of modern health care. It can only be performed with sufficiently detailed data sources describing each segment of care. In case of significant heterogeneity and lack of standardization of hospital information systems it is necessary to fully exploit existing parametric data sources. The valid systems for Czech cancer care: the National Cancer Registry, clinical registries of Czech Society for Oncology of the Czech Medical Association of J.E. Purkyne, registries of screening programs and administrative data form healthcare payers. From these registries we can obtain a very complex and detailed view on prevention, diagnosis and cancer treatment in the Czech Republic. To achieve this goal, which means more integrated and comprehensive utilization of national registries, surveys and administrative data, it is necessary to fully utilize and apply the current legislative framework, in particular provision of the Act no. 372/2011 Sb.Key words: clinical registry - evaluation of health care - information system - legislation - malignant tumor - population.

    1995-09-01

    Thirteen moladvites have been found on the surf side of the gravel beaches on the shore of the Jesenice water reservoir on the Odrava River. This spur lies about 1 250 m NW of the village Okrouhl at Cheb in Western Bohemia, Czech Republic, where only slightly rounded Pliocene gravels of the Vildgtejn Formation outcrop on the surface and form the bottom of the reservoir at this point. These gravels are also uncovered at the Tekaz Cheb gravel pit, 2 350 m to the NW from the find site. The bottom of the gravel pit and the basement of the moldavite-bearing gravel sands consist of the Miocene Cypris claystones. Red-brown andalusite and feldspar grains are typical minerals of the sandy gravels. The moldavites are lat in shape with deep sculpture, formed in a weakly acidic environment. Moldavites did not undergo prolonged transportation from the site of fall. Two samples have sharp grooves. The moldavites from the Cheb Basin are somewhat smoother to the touch and not as sharp as the moldavites from the Ceske Budejovice-Trebon area in Southern Bohemia. In a microscope, very fine secondary sculpture can be seen, probably formed in the water of the reservoir. The glass-matter is pure inside the samples and thus this is apparently repeated emphasizing of the original sculpture. The biggest specimens are No. 1 (5.44 g; 3 x 1.6 x 0.7 cm) and No. 8 (4.855 g; 3.2 x 1.7 x 0.5 cm). Their color ranges from bottle green to light bottle green to olive green or olive brown in two samples. In the shape, color, high content of bubbles and lechatelierite grains, density (rho = 2.34 - 2.38), refractive index (n = 1.4888 - 1.4936), and chemical composition of sample No. 5 (microprobe analysis: SiO2 - 78.70 wt. %, TiO2 - 0.35, Al2O3 - 10.13, FeO - 1.62, MnO - 0.12, MgO - 2.03, CaO - 3.11, Na2O - 0.42, K2O - 2.61) the moldavites of the Cheb Basin correspond to moldavites from the Ceske Budejovice-Trebon area in Southern Bohemia (1,2). The finds of moldavites in the Cheb Basin reflect the

    2011-09-01

    Two measurement campaigns near busy freeway and suburban crossroad (different traffic intensity) were carried out in Prague city. Both of the two traffic related campaigns were supported with simultaneous measurements at suburban background site to compare measured values with corresponding city background. Extensive set of aerosol instrumentation was used during both campaigns at both measurement sites. Two aerosol spectrometer sets (SMPS and APS) were used to monitor aerosol particle number size distribution. Two BLPI provided information about mass size distribution and chemical composition of collected size resolved aerosol samples. The crossroad campaign was also supported by two EC/OC field analysers providing information about elemental and organic carbon concentrations. Consequent chemical analysis of collected size resolved samples comprised of ion chromatography (water soluble ions), PIXE (elements) and RBS (carbon). Results obtained from spectrometers and BLPIs showed that the main contribution of traffic in ultrafine size range can be attributed to direct exhaust emissions, while the coarse fraction was dominated mainly by regional background aerosol with small traces of brake and tyre abrasion as well as the resuspension of the road dust. Chemical analysis demonstrated that most of the water soluble ions can be found in fine fraction of mass distribution and mostly comes from regional background and long range transport. Most of major elements were found in coarse fraction of mass size distribution and it can be attributed to three different sources: abrasion of different vehicle parts (Fe, Cu, Mn and Zn), resuspension of the road dust (Si, Al, Ca) and long range transport or regional background (Ca and K). Elemental carbon concentration (diesel engine emissions) was found to be proportional to traffic intensity.

    2016-03-01

    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. PMID:26860069

    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

    Zámková, Martina; Blašková, Veronika

    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.

    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

Samples were pooled based on the decade of sampling, age, gender, and three geographical areas; in adults, one pooled samples consisted of ten and in children of twenty individual samples. Altogether 233 pooled samples were analyzed. For all organochlorine pesticides (OCPs), significant downward trends were observed in the period 1970-1990 (p<0.001). The levels of HCB exceeded the Biomonitoring Equivalent (BE) value. The hazard quotient (HQ) in Prague and Ostrava during the 1970s and 1980s was about 40 and in the 1990s it had dropped to about five. In Uherské Hradiště, the HQ in 1975 was one order of magnitude higher (about 170), and had decreased to approximately 12 by 1987. For both HCB and the DDT sum, the BE-related carcinogenic risk of actual concentrations in the past exceeded significantly the individually accepted cancer risk level of 10(-4). The levels of the main PCB congeners in the 1970s through 1990s revealed an upward time trend in all analyzed strata. The highest concentrations were found in the serum of residents from the hot-spot area Uherské Hradiště. Critical PCB sum concentration levels (700ng/g lipid for vulnerable population groups and 1800ng/g lipid for other population groups) were substantially exceeded with an increasing time trend. PCB sum had exceeded HBM II values of 7μg/L of serum since 1980 in all age strata. In conclusion, the body burden of the Czech general population relative to persistent organic pollutants (POPs) in the period 1970 through 1990 significantly exceeded currently existing health based limit values. The past exposure might adversely affect the

    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.

    2000-04-01

    For the first time an anonymous survey by means of questionnaires on the scope and surgical treatment of strabism was used in the Czech Republic in 1998. In 54 departments of the Czech Republic 3167 operations of strabism were made. 80% of the operated patients were children under 15 years of age. The most frequent primary surgical operation was modification of the strength of horizontal muscles. This surgical procedure was implemented in 81.7%. The ratio of primary operations and re-operations in child patients was 10:1. The mean age of child patients during the primary operation of strabism was 4.3 years, on re-operation 7.2 years, the mean period of hospitalization during the primary operation was 4.4 days. Two surgical centres performed more than 20 operations per month. As a matter of routine a surgical microscope was used only by some departments which made less than 5 operations of children suffering from strabism per month. In order to follow up national trends of surgery of strabism the authors will repeat similar investigations in future. PMID:10874792

    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. PMID:25616129

  1. Climate forcings of past droughts in the Czech Lands

    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.

  2. Pedigree analysis of Czech Holstein calves with schistosoma reflexum

    PubMed Central

    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

  3. Contribution to the origin of progeny in middle European Habsburgs: skeletal roentgencephalometric analysis of the Habsburgs buried in Prague.

    From comparisons of roentgencraniometric findings in the first Habsburgs on the Bohemian throne (1526-1612) reduction of the length of the anterior cranial base is obvious and is also consistent with reduction of the depth of the maxilla. The findings are consistent with the small cranium and skull capacity of these Habsburgs. The maxilla is therefore not retrusive, even in Rudolf II where it is affected by a pathological process. The body of the mandible is not reduced which causes a disproportion due to the short anterior base and the maxilla. The disproportion in Ferdinand I and Maxmilian II is compensated by posterior rotation of the mandible. In Rudolf II the body of the mandible is markedly prolonged, the lower jaw is displaced forward and the finding can be described as true progenia. It is evidenced by the shorter anterior base and maxilla of the emperor. Habsburg progenia is thus evident in Central European Habsburgs only in Rudolf II, probably due to the traits of his mother from the Spanish branch of the Habsburgs. The parameters of the lower jaw of father Maxmilian II and grandfather Ferdinand I, however, do not exclude a certain predisposition to progeny in the Central European Habsburg family. The cranium of the first Habsburg on the Czech throne, Ferdinand I, is typical in the high maxillary portion of the face with a markedly posterior rotation of the mandible and a steep position of the upper and lower incisors. The cranium of his wife Anna Jagellonska, on the other hand, is typical in bimaxillary protrusion. In the son Maxmilian II, as a trait from the maternal side, the face is not prolonged, the incisors procline well and the occlusion is normal. In Rudolf II the face is shorter due to the overclosure of the mandible and the pathological process of the maxilla. Anthropological examination of all three generations of emperors revealed increasing brachycrania, a narrow highly vaulted forehead with a non-indented nasal root, poorly developed

    The National Register of Joint Replacements of the Czech Republic was established as part of the National Health Information System in 2002. The register's administrator is the Institute of Health Information and Statistics of the Czech Republic, the Czech Society for Orthopaedics and Traumatology acts as its guarantor of scientific quality. The register is financed from governmental sources. It was launched into full operation in 2003 and it currently focuses on hip joint replacements. Register of knee and shoulder joint replacements is in the process of preparation. The register provides aggregate epidemiological data and other statistics, including the Revision Rate (RR) and curves of cumulative survival probability (Kaplan-Meier) for the main monitored groups of patients and implants used. In years 2003-2012 there were 101,734 primary implantations and 13,459 revision surgeries registered. In terms of gender distribution there is a predominance of females amounting to 59.4% in primary implantations and to 63.49% in revision surgeries. The age structure covers the entire range of adult population; however, more than 50% of the replacements are being implanted between 60-74 years of age. Most frequent indications for primary implantation are primary coxarthrosis (69.85%), post-fracture conditions (13.41%) and post-dysplasia arthritis (8.73%). The most frequent indications for revision surgery are aseptic loosening of acetabular component (38.15%), aseptic loosening of femoral component (22.01%) and recurrent dislocation (6.5%). 45,450 (44.68%) of primary implantations were cemented, 36,477 (35.86%) uncemented, 16,559 (16.28%) hybrid with cemented femur and 656 (0.64%) hybrid with cemented acetabulum. There were also records of 2,592 cervicocapital prostheses (2.55%). Most commonly used is the classic anterolateral approach 75.86% in primary implantations and 50.06% in revision surgeries. Mini-invasive approaches in primary implantations did not exceed 3.2% of all

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

    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 Political Board of the Central Committee of the Czechoslovak Communist Party started to study the possibilities of creating a rocket industry after the first flight into space and particularly after US nuclear weapons were based in Italy

  7. Introduction to the 30th volume of Inverse Problems

    NASA Astrophysics Data System (ADS)

    Louis, Alfred K.

    2014-01-01

    The field of inverse problems is a fast-developing domain of research originating from the practical demands of finding the cause when a result is observed. The woodpecker, searching for insects, is probing a tree using sound waves: the information searched for is whether there is an insect or not, hence a 0-1 decision. When the result has to contain more information, ad hoc solutions are not at hand and more sophisticated methods have to be developed. Right from its first appearance, the field of inverse problems has been characterized by an interdisciplinary nature: the interpretation of measured data, reinforced by mathematical models serving the analyzing questions of observability, stability and resolution, developing efficient, stable and accurate algorithms to gain as much information as possible from the input and to feedback to the questions of optimal measurement configuration. As is typical for a new area of research, facets of it are separated and studied independently. Hence, fields such as the theory of inverse scattering, tomography in general and regularization methods have developed. However, all aspects have to be reassembled to arrive at the best possible solution to the problem at hand. This development is reflected by the first and still leading journal in the field, Inverse Problems. Founded by pioneers Roy Pike from London and Pierre Sabatier from Montpellier, who enjoyably describes the journal's nascence in his book Rêves et Combats d'un Enseignant-Chercheur, Retour Inverse [1], the journal has developed successfully over the last few decades. Neither the Editors-in-Chief, formerly called Honorary Editors, nor the board or authors could have set the path to success alone. Their fruitful interplay, complemented by the efficient and highly competent publishing team at IOP Publishing, has been fundamental. As such it is my honor and pleasure to follow my renowned colleagues Pierre Sabatier, Mario Bertero, Frank Natterer, Alberto Grünbaum and Bill Symes in their big footsteps, and I consider it a privilege to thank all that have contributed to the success of the journal. In its 30 years of existence, the journal has evolved from a trimestral to monthly print publication, now paralleled by an electronic version that has led to publication speeds unheard of when the journal began. This timely publication is especially important for younger researchers, but equally for experienced ones, who in that respect still feel young. In addition, the scope has changed to focus more precisely on the core of inverse problems, characterized, for example, by data errors, incomplete information and so on. In the beginning, fields where questions were considered to lead to inverse problems were listed in the journal's scope to make it clear that the problems being discussed were inverse problems in character. With the development of the solution methods, we now see that inverse problems are fundamental to almost all areas of research. The journal now hosts a number of additional features. With Insights we provide a platform for authors to introduce themselves and their work group, and present their scientific results in a popular and non-specialist form. Insights are made freely available on the journal website to ensure that they are seen by a wider community, beyond the immediate readership of the journal. Special issues are devoted to fields that have matured in such a way that the readers of our journal can profit from their presentation when the time for writing text books has not yet come. In addition, the different approaches taken by different contributors to a special issue disclose the multiple aspects of that field. With Topical reviews we aim to present the new ideas and areas that are stimulating future research. We are thankful that highly acclaimed authors take the time to present the research at the forefront of their respective fields. It is always very enlightening to read these articles as they introduce challenging research domains in condensed form. The diversity of the different topics is especi

    Growth references are important for paediatric health monitoring. It is critical to understand differences in growth interpretation and potential consequences when using available growth references. This study compares the growth of Czech breastfed children with the current WHO growth standards 2006 and the Czech references 1991, 2001. A total of 960 infant/parent pairs in the Czech Republic were recruited through paediatric practices. Anthropometric data were collected during infants' first 12 months of life and parent questionnaires were gathered during a preventive visit at 18 months. Czech breastfed infants were longer with a greater head circumference at all percentiles compared to the WHO standards and were similar to the national references. The percentile weight-for-age and weight-for-length values of infants (: 6 months) were lower, and higher (6-12 months) compared to the WHO standards. The infant growth in the sample differed from both the WHO standards as well as the national references. Our findings indicate that the growth of Czech breastfed children differs from the current national references. These discrepancies were smaller compared to the WHO standards. The results of the study were used for new growth assessment guidelines to optimize feeding recommendations for Czech infants. The adoption of the WHO standards in the Czech Republic is not recommended. PMID:26036096

    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. PMID:25990114

    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 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.

    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.

    Pigeon, doves and songbirds are hosts of the parasite Trichomonas gallinae (Rivolta, 1878), which causes avian trichomonosis. Raptors are infected when they digest infected prey. A high percentage of the diet of Eurasian sparrowhawk Accipiter nisus (Linnaeus) is comprised of birds. During the breeding season 2012 and 2013, we clinically tested 298 nestling Eurasian sparrowhawks from urban and rural areas of the Czech Republic for the presence of trichomonads. Sparrowhawk nestlings in the urban area were more infected (32.9%) than in the rural area (12.2%) in 2012 (χ(2) = 6.184, P = 0.045). The number of infected nestlings dropped in the urban area (5.4%) and remained similar in the rural area (16.6%) in 2013. Sequences of ITS region and SSU rDNA confirmed that the isolates from infected sparrowhawk nestlings belonged to Trichomonas gallinae. PMID:26198549

    The large‐scale change of Czech society since 1989 has involved the democratic transformation of the health system. To empower the patient was one important goal of the healthcare reform launched immediately after the Velvet Revolution. The process has been enhanced by the accession of the Czech Republic to the European Union and the adoption of important European conventions regulating the area. The concept of informed consent and a culture of negotiation are being inserted into a traditionally paternalistic culture. Our article describes the current situation on the issue of the communication of information on state of health and treatment, and on the question of the participation of the patient in decisions on treatment. We present empirical results of a public opinion survey on this issue. The results show a still prevailing submissive attitude towards the physicians, despite the fact that the concept of informed consent has become more and more publicly familiar (42% of respondents gave the completely correct answer regarding informed consent). The impact of age, education and sex on answers to the questionnaire was analysed. Men, younger and more educated respondents were more likely to show the autonomous attitude, whereas women, older and less educated people tended to show the traditional submissive attitude. Further, our article raises the question of the cultural and historical background within which the current ethically and legally binding norms (products of western democracies, in fact) are interpreted. The question is how far cultural modifications are tolerable in the practical implementation of universal ethical constructs (informed consent). PMID:17470503

    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.

    The Czech Republic Global Youth Tobacco Survey (GYTS) is a school-based survey of students in grades 7-9, conducted in 2002. A two-stage cluster sample design was used to produce representative data for all of the Czech Republic. On a large sample of students (N=4,149) from 7-9th grade it reveals that smoking among children has been continually growing. According to the results of this study, over 34% of the respondents smoke. Results of the study help us to understand social and attitudinal factors that affect adolescent smoking habits. Social factors include particularly the convenient availability of cigarettes and the lack of the legal regulation of the retail of cigarettes: over one half of all smokers under 15 years of age regularly purchase cigarettes in regular retail outlets; 72% of them reported never having been restricted in their purchases because of their age. Advertising and media coverage appears to be another important factor that affects smoking in this age group. Over 80% of children under 15 years of age reported that they have been exposed to the tobacco advertising. The study also allows an interesting analysis of the exposure to the environmental tobacco smoke. Compared to non-smokers, this exposure has been significantly higher in the case of smokers--both in their homes and at other locations (58% vs. 25%, and 90% vs. 57% respectively). The analysis of the data also revealed a strong misconception about the health risks related to passive smoking among smokers. The study provides three key findings for health promotion: (1) it is necessary to exert a continuous pressure on the political representation to strictly enforce the regulations of tobacco distribution and availability to minors; (2) school health education as well as community oriented prevention programs need to explicitly communicate non-smoking as a standard; and (3) it is important to increase the attractiveness and availability of smoking cessation programs.

    This is one of the first studies, which compares the level of stigmatizing behaviour in countries that used to be on the opposite sides of the Iron Curtain. The aim was to identify the prevalence of reported and intended stigmatizing behaviour towards those with mental health problems in the Czech Republic and to compare these findings with the findings from England. The 8-item Reported and Intended Behaviour Scale (RIBS) was used to assess stigmatising behaviour among a representative sample of the Czech population (n=1797). Results were compared with the findings of an analogous survey from England (n=1720), which also used the RIBS. The extent of reported behaviour (i.e., past and present experiences with those with mental health problems) was lower in the Czech Republic than in England. While 12.7% of Czechs reported that they lived, 12.9% that they worked, and 15.3% that they were acquainted with someone who had mental health problems, the respective numbers for England were 18.5%, 26.3% and 32.5% (P<0.001 in each of these items). On the other hand, the extent of intended stigmatizing behaviour towards those with mental health problems is considerably higher in the Czech Republic. Out of maximum 20 points attached to possible responses to the RIBS items 5-8, Czechs had a lower total score (x=11.0, SD=4.0) compared to English respondents (x=16.1, SD=3.6), indicating lower willingness to accept a person with mental health problems (P<0.001). The prevalence of stigmatizing behaviour in the Czech Republic is worrying. Both, further research and evidence based anti-stigma interventions, should be pursued in order to better understand and decrease stigmatizing behaviour in the Czech Republic and possibly across the post-communist countries in Central and Eastern Europe.

    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.

    of large quantities of spatially and non-spatially referenced data. For data integration of agriculture data FOODIE introduced the open data model. 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 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. PMID:25464037

  5. Congenital cataract, facial dysmorphism and demyelinating neuropathy (CCFDN) in 10 Czech gypsy children – frequent and underestimated cause of disability among Czech gypsies

    2014-01-01

    Background Congenital Cataract Facial Dysmorphism and demyelinating Neuropathy (CCFDN, OMIM 604468) is an autosomal recessive multi-system disorder which was first described in Bulgarian Gypsies in 1999. It is caused by the homozygous founder mutation c.863 + 389C > T in the CTDP1 gene. The syndrome has been described exclusively in patients of Gypsy ancestry. The prevalence of this disorder in the Gypsy population in the Czech Republic and Central Europe is not known and is probably underestimated and under-diagnosed. Methods We clinically diagnosed and assessed 10 CCFDN children living in the Czech Republic. All patients are children of different ages, all of Gypsy origin born in the Czech Republic. Molecular genetic testing for the founder CTDP1 gene mutation was performed. Results All patients are homozygous for the c.863 + 389C > T mutation in the CTDP1 gene. All patients presented a bilateral congenital cataract and microphthalmos and had early cataract surgery. Correct diagnosis was not made until the age of two. All patients had variably delayed motor milestones. Gait is characteristically paleocerebellar in all the patients. Mental retardation was variable and usually mild. Conclusions Clinical diagnosis of CCFDN should be easy for an informed pediatrician or neurologist by the obligate signalling trias of congenital bilateral cataract, developmental delay and later demyelinating neuropathy. Our data indicate a probably high prevalence of CCFDN in the Czech Gypsy ethnic subpopulation. PMID:24690360

    In order to identify polymorphic sites and to find out their frequencies and the frequency of haplotypes, the complete D-loop of mitochondrial DNA (mtDNA) from 93 unrelated Czech Caucasians was sequenced. Sequence comparison showed that 85 haplotypes were found and of these 78 were unique, 6 were observed twice and 1 was observed three times. Genetic diversity (GD) was estimated at 0.999 and the probability of two randomly selected sequences matching (random match probability, RMP) at 1.2%. Additionally these calculations were carried out for hypervariable regions 1, 2 (HV1, HV2), for the area between HV1 and HV2 and for the area of the hypervariable region HV3. The average number of nucleotide differences (ANND) was established to be 10.2 for the complete D-loop. The majority of sequence variations were substitutions, particularly transitions. Deletions were found only in the region where HV3 is situated and insertions in the same place and in poly-C tracts between positions 303 and 315 in HV2. A high degree of length heteroplasmy was found especially in the regions of poly-C tracts between positions 16184 and 16193 in HV1 and between positions 303 and 315 in HV2. Position heteroplasmies were found in two cases. PMID:14593483

    Increasing demands for precise GNSS levelling in the Czech Republic as well as exclusively available gravity and terrain data raised up the realization of a more accurate transformation between the ETRS and the vertical reference system Bpv (Baltic after adjustment), known also as a quasigeoid model. In order to meet high accuracy requirements for the model, the setting and the solution of the geodetic boundary value problem were reconsidered. The problem is formulated for gravity disturbances and the representation formula for the solution was derived by means of the Green's function method constructed for an oblate ellipsoid of revolution. Resulting integral kernel, as an analogue to the so-called Hotine function, was used in the convolution for numerical evaluation of the disturbing potential. The difference between the ellipsoid and the terrain was taken into account through successive approximations. The resulting solution leads to a detailed knowledge of the residual disturbing potential T on the Earth's surface in the area of interest. In addition, restoring the global low-frequency part of T and inserting non-gravitational systematical effects associated with Bpv, that have been identified too, make it possible to interpret the results in terms of height anomalies or quasigeoid heights within the Bpv system. The resolution, accuracy and precision of the transformation between ETRS and Bpv is discussed and compared with the quasigeoid models available today.

    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.

    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.

    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

  12. Natural and anthropogenic enrichments of heavy metals in modern soils: the case study in the Jizera floodplain, Czech Republic

    The timing and realistic quantification of the anthropogenic pollution of soils and sediments are among relevant topics of numerous current environmental geochemistry studies. Geochemical mapping and depth profiling of pollutants in soils and sediments is used for reconstruction of historical pollution and evaluation of previous (cumulative) impacts. In fact, the depth profiles of heavy metals in modern soils are a result of two main processes: deposition of atmospheric fallout (everywhere) or sediment (in floodplains) with anthropogenic components on one hand, and element migration due to biogeochemical processes (Fe oxide transformations, element recycling by plants and joint processes) on the other hand. These processes are not always taken into account, particularly when only one piece of the jigsaw puzzle is in focus, such as development of pollution proxy (e.g., stable lead isotope ratios, MS) or geochemical mapping. Mature soils, of which surface strata are enriched in heavy metals, are too complex systems to allow simple distinguishing natural and anthropogenic portions of that enrichment; possible natural enrichment factor (EF) ~1.5 has been assumed in the case of Pb and Zn by Reimann et al. Floodplains can offer a "natural isolation of pieces of jigsaw puzzle", if deposition and erosion in the floodplain have alternated in the past (such behaviour is relatively common). This alteration can produce terraces or related sediment units of different age, but composed of sediment with the same geochemistry, i.e. material with the same provenance and after the same hydraulic sorting before the deposition. We studied fluvisols in the Jizera floodplain (~50 north-east from Prague, Czech Republic), where a terrace is present along the currently inundated floodplain. We found that atmospheric fallout and/or past pedogenic processes in the terrace above that active floodplain do not cause enrichment of Cr, Cu, Ni, and Zn; perhaps there is an exception for Pb.

    In this paper, activity concentrations of radiocesium in mushrooms from various locations in the Czech Republic and the Slovak Republic in the years 2000-2004 are presented. Summary reports of Czech regulatory bodies have judged the average activity concentrations in mushrooms to be remarkably below the maximum permissible level of contamination. However, there are certain regions where radiocesium activities have approached the maximum permissible level for contamination of basic foodstuff. For example, the highest activity concentration of (137)Cs measured by gamma-spectrometry was 2,263 Bq kg(-1) (on a dry mass basis), in Xerocomus badius from Staré Ransko (a locality in the Czech-Moravian Highlands, Czech Republic). The highest activity concentration of (137)Cs measured in Slovakia was 966 Bq kg(-1) (on a dry mass basis), for Suillus luteus from Senica. For comparison, the corresponding activity concentration in a sample taken within the 30 km zone around Chernobyl was measured to be 6,000 Bq kg(-1) (on a dry mass basis). Our results have also demonstrated remarkably lower activity concentrations of (137)Cs in Slovakia compared to those in the Czech Republic. PMID:16628432

    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. 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).

    of large quantities of spatially and non-spatially referenced data. For data integration of agriculture data FOODIE introduced the open data model. 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 main aim of the eGovernment programme in the Czech Republic is to enhance the efficiency of public administration. The Digital Map of Public Administration (DMVS) should be composed of digital orthophotographs of the Czech Republic, digital and digitised cadastral maps, digital purpose cadastral map (ÚKM) and a technical map of municipality, if available. The DMVS project is a part of computerisation of public administration in the Czech Republic. The project enhances the productivity of government administration and also simplifies the processes between citizens and public administration. The DMVS project, that should be compliant with the INSPIRE (Infrastructure for Spatial Information in the European Community) initiative, generates definite demand for geodata on the level of detail of land data model. The user needs that are clearly specified and required are not met due to inconsistencies in terminology, data management and level of detail.

    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 Czech Republic, England, France, Germany and Sweden differ culturally and economically, but they commonly exhibit general trends of decentralisation in the control of educational processes and outcomes. The present contribution looks at these five European countries as the venue for case studies in educational restructuring as well as evaluation, assessment and reporting. It shows that such trends have been most radical in the Czech Republic and Sweden, while England has centralised curriculum policy and France has devolved some decision-making to bodies at lower levels, but as representatives of the central state.

  2. Site Selection and Geological Research Connected with High Level Waste Disposal Programme in the Czech Republic

    Attempts to solve the problem of high-level waste disposal including the spent fuel from nuclear power plants have been made in the Czech Republic for over the 10 years. Already in 1991 the Ministry of Environment entitled The Czech Geological Survey to deal with the siting of the locality for HLW disposal and the project No. 3308 ''The geological research of the safe disposal of high level waste'' had started. Within this project a sub-project ''A selection of perspective HLW disposal sites in the Bohemian Massif'' has been elaborated and 27 prospective areas were identified in the Czech Republic. This selection has been later narrowed to 8 areas which are recently studied in more detail. As a parallel research activity with siting a granitic body Melechov Massif in Central Moldanubian Pluton has been chosen as a test site and the 1st stage of research i.e. evaluation and study of its geological, hydrogeological, geophysical, tectonic and structural properties has been already completed. The Melechov Massif was selected as a test site after the recommendation of WATRP (Waste Management Assessment and Technical Review Programme) mission of IAEA (1993) because it represents an area analogous with the host geological environment for the future HLW and spent fuel disposal in the Czech Republic, i.e. variscan granitoids. It is necessary to say that this site would not be in a locality where the deep repository will be built, although it is a site suitable for oriented research for the sampling and collection of descriptive data using up to date and advanced scientific methods. The Czech Republic HLW and spent fuel disposal programme is now based on The Concept of Radioactive Waste and Spent Nuclear Fuel Management (''Concept'' hereinafter) which has been prepared in compliance with energy policy approved by Government Decree No. 50 of 12th January 2000 and approved by the Government in May 2002.

    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 218Po; 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.

    Lysosomal lipase deficiency is a hereditary autosomal recessive enzymopathy leading to lysosomal storage of triacylglycerols (TAG) and cholesterol esters (CE). In particular cells with a permanently high receptor-mediated LDL endocytosis are affected (liver, kidneys). There are two basic phenotypes. The fatal infantile phenotype (Wolman's disease) with generalized storage of both types of apolar lipids. This form was diagnosed in this country only once. The opposite is the protracted, oligosymptomatic form encountered in all age groups. It is characterized by the storage of CE (which gave this entity the name of cholesteryl storage disease--CESD). Its main sign is affection of the liver (hepatomegaly, hepatopathy), which in some instances may lead to organ failure, directly or after cirrhotic transformation. Furthermore there is permanent hypercholesterolaemia (high LDL cholesterol) due to increased VLDL synthesis by hepatocytes, low HDL cholesterol and variably raised TAG. This constellation of blood lipids is a risk factor for the development of atherosclerosis. In the course of 25 years in the Czech Republic 13 cases of CESD were diagnosed in 11 families. Ten of these cases were characterized by clinically manifest hepatopathy with hepatomegaly, detected incidentally during medical examinations (at the age of 2-14 years). In three adult patients with permanent hypercholesterolaemia the storage process was subclinical and the diagnosis was established quite incidentally by examination of non-specific secondary and tertiary manifestations of the disease. The diagnosis was established in all cases of CESD at the tissue level (liver biopsy), at the biochemical (acid lipase deficiency) and molecular genetic level (mutation in enzyme locus). In all instances mutation of G934A was found leading to reduction and loss of the eighth exon. This mutation was present in five patients in a homozygous state. Six mutations were heterozygous. In one instance for technical

    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.

    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.

  7. Documentary and instrumental-based drought indices for the Czech Lands back to AD 1501

    2016-04-01

    This study addresses the reconstruction of four slightly different drought indices in the Czech Lands (recent Czech Republic) back to 1501 AD. Reconstructed monthly temperatures for central Europe that are representative for the Czech territory, together with reconstructed seasonal precipitation totals from the same area, are used to calculate monthly, seasonal and annual drought indices (SPI, SPEI, Z-index, and PDSI). The resulting time-series reflect interannual-to multi-decadal drought variability. The driest episodes cluster around the beginning and end of the 18th century, while 1540 emerges as a particularly dry extreme year. The temperature-driven dryness of the past three decades is well captured by SPEI, Z-index and PDSI, whereas precipitation totals show no significant trend during this period (as reflected in SPI). Data and methodological uncertainty associated with Czech drought indices, as well as their position in a greater European context, are critically outlined. Further discussion is devoted to comparison with fir tree-rings from southern Moravia and a spatial subset of the "Old World Drought Atlas" (OWDA), which reveals significant correlation coefficients, of around 0.40 and 0.50, respectively. This study introduces a new documentary-based approach for the robust extension of standardized drought indices back into pre-instrumental times, which we also believe has great potential in other parts of the world where high-resolution paleoclimatic insight remains as yet limited.

  9. 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.

    Czech Republic joined European action plan on alcohol for years 2000 to 2004 and signed its accomplishment. However, since 2000 situation has worsened. Alcohol consumption raised in 2001 (the last known data) to 10.0 litters of 100% alcohol (that is 159.9 litters of beer, 8.2 litters of distillates and 16.2 litters of wine per person per year). The only positive aspect was the small rise of consumption tax in distillates and that some thesis of the European action plan on alcohol were included into the governmental document "Long-term improvement of the health status of the population in Czech republic--Health for everybody in the 21st century". The proclamation has had no practical effect. Highly adverse is the situation with alcohol consumption in children and adolescents, which was described in the last study. Risks related to the high alcohol consumption in Czech republic include: High incidence of alcohol related death, including children, adolescents and young people (injuries, traffic accidents, poisonings, suicides, liver and tumor diseases); higher morbidity; lower productivity at work and worse position of Czech workers in concurrent environment; worse reproduction health, higher incidence of inborn defects caused by alcohol taken during pregnancy (including its beginning, when women do not know it); frequent social and family problems caused by alcohol abuses; increased risk of consumption of non-alcoholic drugs in children and adolescents. Alcohol belong to throughway drugs and its consumption in early age represents for children and adolescents a risk factor for other addictive drugs; alcohol is related namely to violent and negligent delicts; flagrant alcohol excesses together with alcohol related criminality harm the prestige of Czech Republic to foreign visitors and can drive them back.

    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.

    2010-05-01

    In Integrated Water Resources Management planning the effects of changing natural conditions (natural water availability) and socio-economic development (water demand) must be taken into consideration. Climate change will influence the water availability. In some sectors, e.g. agricultural irrigation, also the water demand is influenced by climatic conditions. Both, the development of natural water availability and water demand, are connected with certain levels of uncertainty. Therefore, scenarios of socio-economic development and climate change are required for Integrated Water Resources Management planning. The river Elbe basin (catchment area approximately 150,000 km²) is located in central Europe. The river Elbe basin is a trans boundary river basin. One third is located in the Czech Republic upstream of Germany, where two thirds of the basin is located. Therefore, inflows from the Czech part are important for instance for navigation in the German part. For navigation an inflow to Germany of 100 m3/s is required. Due to climate change the inflows are expected to decline. In the project GLOWA-Elbe a water management model for the whole river Elbe basin was developed. The model for the Czech part includes among others 52 reservoirs, 20 thermoelectric power plants, 70 hydroelectric power plants, 30 industrial users, 15 agricultural irrigation users, 40 public water utilities, and 160 waste water treatment plants. Two global socio-economic trends are renationalized and used in the simulations. Renationalized climate data are used to simulate the effects of climate change on natural discharges. Using the water management model the effects of global change on inflows from the Czech Republic to Germany are simulated. Using this model is it analyzed, if reservoir management in the Czech part can sustain a required inflow of 100 m3/s to Germany.

    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

    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

    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.

    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.

    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. PMID:23227241

    Treponema pallidum subsp. pallidum (TPA) is the causative agent of the sexually transmitted disease syphilis. In the Czech Republic, several hundred cases of syphilis are reported annually; e.g. in 2012, 696 syphilis cases were documented. In the last decades, an increasing prevalence of macrolide resistant TPA strains harboring A2058G or A2059G mutations in the 23S rRNA gene has been reported. Macrolides were used (and rarely are still being used) in the Czech Republic for the treatment of syphilis in patients allergic to penicillin. While 37% of TPA strains were resistant to macrolides between 2004 and 2010, this rate increased to 67% between 2011-2013. High prevalence of A2058G or A2059G mutations and increasing rates of macrolide resistant TPA strains have also been documented in other developed countries. Therefore, macrolides should not be used in the treatment of syphilis. PMID:25872989

    In this paper, we analyse the occurrence of BLAD and CVM heterozygous animals in Holstein cattle in the Czech Republic in 1993-2005. The occurrence of BLAD heterozygous sires and heifers (BL) during the period 1993-1998 in Czech Holsteins was 13.9% and 10.7%. Radical measures have been taken to restore the population. Evidently, the measures have been efficient, in 2005 one BLAD heterozygous sire of 101 was found. Continuous testing is necessary, because in commercial herds, the eradication process is not short-term. The found occurrence ofCVM heterozygous sires (CV) decreased from 20% in 2001 to 8% (7 positive of 85) in 2005.This is still quite a high frequency. The occurrence in CV females of 20% remains higher. Therefore, the use of CV sires should be restricted thoroughly. Identification of the molecular basis for inherited diseases, should lead to control measures which would enable the quick recovery of the population. PMID:19113030

    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.

    Mining for coal and its utilization have various impacts on the surrounding environment. Huge volumes of waste materials which are by-products of both the underground and open cast coal mining, pose one of the major environmental hazards in addition to air pollution caused by coal burning in power plants in the Czech Republic. Some of these risks could be reduced when having accurate and comprehensive data on coal quality. Statistical data processing of almost 35,000 coal samples from Late Paleozoic and Tertiary coal basins of the Czech Republic provided a unique information on the quality of lignite, sub-bituminous and bituminous coals and anthracites including the content of toxic trace elements (As, Be, Hg, Pb and Se). In this context related environment and health risks and protection implications are discussed. PMID:16218333

    Background This paper contributes to research in health systems literature by examining the role of health boards in hospital governance. Health care ranks among the largest public sectors in OECD countries. Efficient governance of hospitals requires the responsible and effective use of funds, professional management and competent governing structures. In this study hospital governance practice in two health care systems – Czech Republic and New Zealand – is compared and contrasted. These countries were chosen as both, even though they are geographically distant, have a universal right to 'free' health care provided by the state and each has experienced periods of political change and ensuing economic restructuring. Ongoing change has provided the impetus for policy reform in their public hospital governance systems. Methods Two comparative case studies are presented. They define key similarities and differences between the two countries' health care systems. Each public hospital governance system is critically analysed and discussed in light of D W Taylor's nine principles of 'good governance'. Results While some similarities were found to exist, the key difference between the two countries is that while many forms of 'ad hoc' hospital governance exist in Czech hospitals, public hospitals in New Zealand are governed in a 'collegiate' way by elected District Health Boards. These findings are discussed in relation to each of the suggested nine principles utilized by Taylor. Conclusion This comparative case analysis demonstrates that although the New Zealand and Czech Republic health systems appear to show a large degree of convergence, their approaches to public hospital governance differ on several counts. Some of the principles of 'good governance' existed in the Czech hospitals and many were practiced in New Zealand. It would appear that the governance styles have evolved from particular historical circumstances to meet each country's specific requirements

    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.

    This paper summarises the results of parasitological examinations of the European eel Anguilla anguilla (Linnaeus) in the Czech Republic, carried out at the Institute of Parasitology, Czech Academy of Sciences (previously the Czechoslovak Academy of Sciences) within the period of 50 years (1958-2008). Even though this survey is limited to the Czech Republic, it provides extensive data probably incomparable with any other study anywhere regarding the number of eels examined and parasites found. A total of 723 eels was examined from 42 localities that belong to all of the three main river drainage systems in the country, i.e. the Elbe, Danube and Oder river basins. Of the 31 species of adult and larval macroparasites including Monogenea (4 species), Trematoda (3), Cestoda (3), Nematoda (11), Acanthocephala (5), Hirudinea (1), Bivalvia (1), Copepoda (1), Branchiura (1) and Acariformes (1), most of them (30) were recorded from the Elbe River basin. These parasites can be divided into three main groups regarding their host specificity: parasites specific for eels (26%), non-specific adult parasites occurring also in other fishes (61%) and non-specific larvae (13%). The highest number (19) of parasite species was recorded in the Mácha Lake fishpond system in northern Bohemia. The parasite communities in eels from the individual localities exhibited large differences in their species composition and diversity depending on local ecological conditions. The parasite fauna of A. anguilla in the Czech Republic is compared with that in other European countries. The nematode Cucullanus egyptae Abdel-Ghaffar, Bashtar, Abdel-Gaber, Morsy, Mehlhorn, Al Quraishy et Mohammed, 2014 is designated as a species inquirenda. PMID:26130652

    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.

    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.

    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 review is performed for the data of local and regional seismographical networks installed in mines of the Ostrava-Karvina Coal Basin (Czech Republic), where underground anthracite mining is carried out and dynamic events occur in the form of rockbursts. The seismological and seismoacoustic observations data obtained in panels that are in limiting state are analyzed. This aggregate information is a basic for determining hazardous zones and assigning rockburst prevention measures.

    Piétrain boars of different ryanodine receptor (RYR1) genotypes (NN, Nn and nn, three boars each) were mated with approximately 10 Czech Large White x Czech Landrace sows (genotype NN) each to produce one litter per sow. The progeny of nn boars had a significantly higher individual weaning weight (7.31 kg versus 6.86 kg) and average daily gain from birth to weaning (252 g/day versus 240 g/day) than the progeny of NN boars. Furthermore, piglets from nn boars differed statistically significant also from piglets of boars with the Nn genotype for these two traits. The litters of the NN boars were greater by 0.5 piglets than the litters of the nn boars for the total number of piglets born, piglets born alive and piglets weaned, but the differences were not significant. The Nn genotype showed for all litter size traits and the number of stillborn piglets the best values. The difference between the genotypes Nn and nn was statistically significant at the 0.05 level for the number of piglets born alive and the number of piglets weaned. PMID:17488359

    Deinstitutionalization has not been pursued in the post-communist Europe until recently. The population of psychiatric patients institutionalized in the regional mental hospitals is, however, largely understudied. The aim of this study is to assess discharges of long-term inpatients with schizophrenia from Czech psychiatric hospitals and to analyse re-hospitalizations within this group. The nationwide register of all-cause inpatient hospitalizations was merged with the nationwide register of all-cause deaths on an individual level basis. Descriptive statistics, survival analysis and logistic regression were performed. 3601 patients with schizophrenia previously hospitalized for more than a year were discharged from Czech mental hospitals between 1998 and 2012. This included 260 patients hospitalized for >20years. Nearly one fifth (n=707) of the long-term patients died during the hospitalization; and discharges of 19.36% (n=697) were only administrative in their nature. Out of 2197 truly discharged patients, 14.88% (n=327) were re-hospitalized within 2weeks after the discharge. The highest odds of rehospitalization were associated with being discharged against medical advice (OR 5.27, CI: 3.77-7.35, p<0.001). These data are important for the ongoing mental health care reforms in the Czech Republic and other countries in the Central and Eastern Europe. PMID:27094718

    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.

    Postwar mortality evolution in the Czech Socialist Republic has run through 2 different stages with the turning point being 1960. Since about the beginning of the 1960s, the mortality level in the Czech Socialist Republic has quickly declined for both sexs and in each age category. The rate of decline has slowed with increasing age. Since the 1960s, the mortality of the older population has ceased to decline or has worsened; with men, this phenomenon spread even as low as 40 years old. Infant and child mortality, male mortality under 40 years of age, and female mortality under 50 years of age positively contributed to a longer life span, except between 1960 and 1970. The present mortality situation in the Czech Socialist Republic is the result of the unfavorable developments of the last 20 years, especially in the decade 1960-1970. The present age structure of mortality is characterized by higher infant mortality, higher male mortality above 40 years of age, and higher female mortality at 50-55 years of age. A certain improvement observed in the last few years is relative, as the mortality of the male population over 30 is the same today as it was 35 years ago and the mortality of the female population is the same as it was in the mid-1960s.

    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. PMID:22504401

    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.

    Bats from the families Rhinolophidae (n = 90) and Vespertilionidae (n = 191) in the USA and Czech Republic were screened for the presence of Cryptosporidium by microscopic and molecular analysis of faecal samples collected from rectum of dissected animals and from the ground beneath roosting sites. Cryptosporidium oocysts were not detected in any of the 281 faecal specimens examined using the aniline-carbol-methyl violet staining method. Nested PCR amplification, sequencing and phylogenetic analysis of the small ribosomal subunit rRNA and actin genes were used to identify isolates and infer evolutionary relationships. Cryptosporidium parvum was identified in a western small-footed bat (Myotis ciliolabrum) from the USA and a common pipistrelle bats (Pipistrellus pipistrellus) from the Czech Republic. Two novel genotypes were identified and named Cryptosporidium bat genotype III and IV. Bat genotype III was found in two big brown bats (Eptesicus fuscus) from the USA. Bat genotype IV was detected in two common pipistrelle bats from the Czech Republic. PMID:26255170

    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.

    This paper presents our first experience with the application of the METRo model, which forecasts road surface temperature and road conditions (e.g., wet or dry surface, ice) in the Czech Republic. In our version, the model uses online measurements from road weather stations (RWS) in the Czech Republic and weather forecasts from ALADIN, the operational numerical weather prediction NWP model of the Czech Hydrometeorological Institute. The METRo model was quasi-operationally tested during the winter season (November 2012-February 2013) using data from 25 RWS. We compared three model runs with an emphasis on road surface temperature. The first run used the original model and served as a reference. The second run applied model output statistics (MOS) to ALADIN forecasts of temperature and humidity at 2 m above the ground, which are required by METRo. The third run applied METRo in a nowcasting mode by starting the model every hour and using new measurements available from the RWS. The results indicated that MOS improved the accuracy of the temperature and humidity at 2 m but had little impact on the forecasted road surface temperature. However, the nowcasting scheme significantly improved the accuracy of the forecasts for the initial 3 to 4 h. The evaluation of the METRo results suggests that the radiation flux forecast is crucial for an accurate road surface temperature forecast.

    The Czech Republic is a country with a well-developed peaceful utilization of nuclear energy and ionizing radiation. Sealed Radioactive Sources (further also SRS) are broadly used in many areas in the Czech Republic, e.g. in research, industry, medicine, education, agriculture, etc. Legislation in the field of ionizing radiation source utilization has been fully harmonized with European Community legislation. SRS utilization demands a proper system which must ensure the safe use of SRS, including the management of disused (spent) and orphaned SRS. In the Czech Republic, a comprehensive system of SRS management has been established that is comparable with systems in other developed countries. The system covers both legal and institutional aspects. The Central Register of Ionizing Radiation Sources is an important part of the system. It is a tracking system that covers all activities related to SRS, from their production or import to the end of their use (recycling or disposal). Many spent SRS are recycled and can be used for other purposes after inspection, repacking or reprocessing. When the disused SRS are not intended for further use, they are managed as radioactive waste (RAW). The system of SRS management also ensures the suitable resolution of situations connected with improper SRS handling (in the case of orphaned sources, accidents, etc.). (author)

    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

    This paper deals with the analysis of the costs, applied, for example, when treating specific diseases - an important aid in prioritizing the process of resource allocation. In our review, the specific disease is dementia caused by Alzheimer's disease. This paper aims to provide more information on the partial costs per patient that are calculated according to the aggregated data from publicly available sources as well as from the results of authors' own investigation. The University Hospital in Hradec Králové and the General Health Insurance Company of the Czech Republic participated in this research. The elementary research objective was to compare the costs per patient diagnosed early onset, to those of the patient diagnosed later. The Czech Republic lacks information regarding dementia. Therefore, these issues require attention. The methods used in this paper included time series analyses, methods of direct questioning, interviews with experts, and analyses of medical documentation. These methods were combined to exploit their particular advantages and to ensure the issues discussed, were covered. The investigation showed that the underpinning of patients with Alzheimer's disease at early onset is advantageous from an economic perspective, because the cost of outpatient care is much lower compared with that of inpatient care. The international comparisons of the volume of care provided should be approached with great caution. These are based solely on the facts of various expert estimates and are not usually supported by hard data. Yet, they still illustrate the overall view of our ability to take care of people with dementia. According to experts, care in the Czech Republic significantly lags behind the rest of developed Europe.

    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.

    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

    Highlights: Black-Right-Pointing-Pointer In this paper, we define lifespan of mobile phones and estimate their average total lifespan. Black-Right-Pointing-Pointer The estimation of lifespan distribution is based on large sample of EoL mobile phones. Black-Right-Pointing-Pointer Total lifespan of Czech mobile phones is surprisingly long, exactly 7.99 years. Black-Right-Pointing-Pointer In the years 2010-20, about 26.3 million pieces of EoL mobile phones will be generated in the Czech Republic. - Abstract: 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.

Departments of Landscape Ecology and GIS Applications from the Silva Tarouca Research Institute for Landscape and Ornamental Gardening, v.v.i. study these changes mainly in the research project MSM 6293359101 Research into sources and indicators of biodiversity in cultural landscape in the context of its fragmentation dynamics, the subpart Quantitative analysis of the dynamics of the Czech landscape development. In this paper, the authors concentrate mainly on map sources, which were acquired for the purpose of the project and also introduce partial results. Maps, which are the sources for the analyses, are following: maps from 2nd Austrian military survey in the scale 1:28 800 (created for the territory of the Czech Republic in the period 1836-1852), maps from 3rd Austrian military survey in the scale 1:25 000 (created for the Czech Republic in the period 1876-1880), Czechoslovak military topographic maps in the scale 1:25 000 from 1950s and 1990s, and Czech topographic base maps in the scale 1:10 000 from 2002-2006. It is necessary to complete maps of the 2nd and 3rd Austrian military survey thanks to their incompleteness, mainly along state borders. Also maps from 1nd Austrian military survey in the scale 1:28 800 (created for the Czech Republic in the period 1764-1783) are available; however, their usage for the accurate analyses in the GIS environment is restricted by their poor cartographic accuracy. Apart of the above mentioned maps, there has been progress in collecting maps from the interwar and war period (revised maps of the 3rd Austrian military survey maps, maps of the provisional military survey from 1923-1933, maps of definitive military survey from 1934-1938 and maps from survey of Moravian part of the Protectorate of Bohemia and Moravia, so called Messtischblätter from 1939-1945).

    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.

    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.

    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

    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.

    Reflecting on a three year long exploratory research of ethics committees in the Czech Republic authors discuss the current role and identity of research ethics committees. The research of Czech ethics committees focused on both self-presentation and self-understanding of ECs members, and how other stakeholders (representatives of the pharmaceutical industry) view them. The exploratory research was based on formal and informal communication with the members of the ethics committees. Members of the research team took part at six regular voluntary meetings of the ethics committees' members, organised by the Forum of Czech Ethics Committees, and at three summer schools of medical ethics. There were realised twenty-five semi-structured interviews as well as six focus group sessions and a participant observation of several regular meetings of three ethics committees. On the grounds of experience from the interviews a simple questionnaire survey was realised among the members of the ethics committees. The ethics committees comprise a community of members working voluntarily, without claims to remuneration or prestige; the unifying goal is protection of subjects of research. The principal working methods are dialogue and agreement. The members of the ethics committees thus, among other things, create an informal community, which can be to a certain extent seen as a Kantian ethical community in a weak sense. The phenomenon of ethics committees can also be described by terms of an epistemic community and a community of practice. These concepts, which are borrowed from other authors and areas, are used as a way how to think of ECs role and identity a bit differently and are meant as a contribution to the current international debate on the topic.

    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.

    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. PMID:26650830

    Eight isolates of the Pea seed-borne mosaic virus (PSbMV) from the Czech Republic were studied regarding their biological and molecular characteristics. Molecular characterization using RT-PCR was done on the 5'(Nter)NIb-CP-UTR3' region amplified using universal CPUP/P9502 primer pair and the newly designed PSB8812/PSB944, and PSB8800/PSB9440 primer pairs, respectively. Sequential and phylogenetic analysis of CP-UTR3' region from all isolates showed that the available Czech and GenBank PSbMV isolates were distributed into 4 clusters in agreement with their diversification and according to their biological characteristics (i.e. pathotype). The molecular data were confirmed by biological testing on different pea cultivars. The Czech isolates were distributed into two pathotypes, the P-1 (7 isolates) and P-4 (1 isolate). PMID:18459836

A total of 1148 different haplotypes were found. The overall haplotype diversity (HD) was determined as 0.998. Analysis of Molecular Variance (AMOVA) reveals non-significant distances between regions concerning their haplotype distribution, thus allowing to use the whole sample as a representative reference database of the Czech Republic. Median network analysis shows a remarkable bipartite composition of the Czech haplotypes, falling in distinct clusters with Eastern and Western European roots. PMID:20215022

  19. Tornadoes within the Czech Republic: from early medieval chronicles to the "internet society"

    NASA Astrophysics Data System (ADS)

    Setvák, Martin; Šálek, Milan; Munzar, Jan

    This paper addresses the historical documentation of tornadoes and the awareness of tornadic events in the area of the present Czech Republic throughout the last nine centuries. 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.

While modelling concentration of low-level ozone proper information about VOC sources and sinks is necessary. VOC are emitted into the atmosphere both from anthropogenic and natural sources. It has been shown in previous studies (e.g. Simpson et al, 1995) that contribution of volatile organic compounds emitted from biogenic sources to total amount of VOC in the atmosphere can be significant. Our work focuses on estimation of VOC emissions from natural ecosystems, most importantly from forests, and its application in photochemical modelling. Preliminary results have shown that inclusion of biogenic emissions in model input data leads to improvement of resulting ozone concentration which encouraged us to work on detailed biogenic VOC emission estimation. Using grid of 1x1km CORINE Land Cover over the area of the Czech Republic, emissions from deciduous, coniferous and mixed forests were estimated aplying the algorithm of Guenther et al., 1995. According to data from Forest Management Institute each cell of model grid has been assigned a proportional composition of each of thirteen tree species which are the the main forest constituents in the Czech Republic. Aggregating data of tree species composition with land cover category emission factor of particular chemical compound (isoprene, monoterpenes) has been obtained for each cell. Annual emissions of VOC on hourly basis have been calculated for domain of the Czech Republic. Biogenic emissions of isoprene and monoterpenes were compared with the emission inventory of anthropogenic sources. The inventory is provided by Czech Hydrometeorological Institute and covers emissions from major stationary sources, area sources (including domestic heating) and mobile sources. Our results show that natural emissions are approximately half the amount of organic compounds emitted

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

    Abstract Background The goal of the study is to evaluate the sensitivity of Czech physicians to the early diagnosis of dementia in patients with memory impairment. Methods A retrospective observational study was designed. We have reviewed the electronic medical records of patients who have been hospitalized for the first time due to dementia of any type at the Kromeriz Mental hospital from January 1, 2012 to December 31, 2013 (24-month period). Pluralistic methods combining the qualitative and quantitative approach were used in this study. Results Dementia of any type was diagnosed in 125 patients in the monitored period. The mean time between patient memory complaints and his / her admission to our facility for their first hospitalization due to dementia was 7.1 years (+- 3.7 years). Most patients with dementia had no prior outpatient treatment of their memory impairment (56.2%); a minority of patients (43.8%) had treatment of their memory impairment by an outpatient physician. Conclusion The sensitivity of Czech physicians to the early diagnosis of dementia is very low. Any delay in starting the treatment of dementia means a worsened effectiveness of this treatment, a worsened quality of life of patients with dementia and their caregivers. Our recommendations for both the early diagnosis and treatment of dementia should be involved in guidelines and should become a part of the pregraduate and postgraduate education of all physicians.

    This paper presents the results of atmospheric radioactivity monitoring over the Czech Republic, as obtained by the Radiation Monitoring Network, following the Fukushima Dai-Ichi Nuclear Power Plant accident. Maximum values for (131)I were 5.6 mBq m(-3) in aerosol form and 13 mBq m(-3) in gaseous form. The maximum values for (134)Cs and (137)Cs were 0.64 and 0.72 mBq m(-3), respectively. The estimated effective half-time for removing the activity from the atmosphere was 6-7 d and 3.5 d for caesium and iodine, respectively. The gaseous-to-total activity ratios of (131)I ranged between 0.3 and 0.9, with an arithmetic mean value of 0.77. The mean value for the (134)Cs/(137)Cs ratios was close to 1.0. The effective inhalation dose due to the accident for an adult living in the Czech Republic was estimated at <4 × 10(-5) mSv, out of which the proportion of (131)I was 88%. PMID:24813185

    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.

    Among the most common non-conventional wastewater treatment techniques used in the Czech Republic are waste stabilisation ponds (WSP), subsurface horizontal flow constructed wetlands (CW) and vertical flow groundfilters (GF). These extensive systems can be advantageously used for treatment of waters coming from sewerages where the ballast weighting commonly makes more than half of dry-weather flow. The monitoring was focused at 14 different extensive systems. Organics removal efficiencies were favourable (CW-82%; GF-88%); in the case of WSP only 57% due to the algal bloom. Total nitrogen removal efficiencies were 43 and 47% for WSP and GF; in the case of CW only 32% due to often occurring anaerobic conditions in filter beds. Total phosphorus removal efficiencies were 37, 35 and 22% for WSP, GF and CW, respectively. Often occurring problems are the ice-blockage of surface aerators at WSP during wintertimes, the pond duckweed-cover or the algal bloom at WSP during summers; a gradual colmatage of filter systems; and the oxygen deficiency in beds of subsurface horizontal flow constructed wetlands. Czech legal regulations do not allow treated wastewater disposal into underground waters. There is only an exception for individual family houses. Up to now, knowledge gained by monitoring of a village (which uses the infiltration upon a permission issued according to earlier legal regulations) have not shown an unacceptable groundwater quality deterioration into the infiltration areas.

    Background Peutz-Jeghers syndrome (PJS) is an autosomal dominant hereditary disease characterized by mucocutaneous pigmentation and gastrointestinal hamartomatous polyposis. The germline mutations in the serine/threonine kinase 11 (STK11) gene have been shown to be associated with the disease. Individuals with PJS are at increased risk for development of various neoplasms. The aim of the present study was to characterize the genotype and phenotype of Czech patients with PJS. Methods We examined genomic DNA of 8 individuals from five Czech families by sequencing analysis of STK11 gene, covering its promotor region, the entire coding region and the splice-site boundaries, and by multiplex ligation-dependent probe amplification (MLPA) assay designed for the identification of large exonic deletions or duplications of STK11 gene. Results We found pathogenic mutations in STK11 gene in two families fulfilling the diagnostic criteria of PJS and in one of three sporadic cases not complying with the criteria. The patient with the frameshift mutation in STK11 gene developed aggressive gastric cancer. No other studied proband has developed a carcinoma so far. Conclusion Our results showed that a germline mutation of STK11 gene can be found not only in probands fulfilling the PJS diagnostic criteria, but also in some sporadic cases not complying with the criteria. Moreover, we observed a new case of aggressive gastric cancer in a young patient with a frameshift mutation of STK11 gene. PMID:19615099

    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

    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.

    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.

    This paper estimates the effect of the abolition of user charges for children's outpatient care (30 CZK/1.2 EUR) in 2009 on the demand for ambulatory doctor visits in the Czech Republic. Because the reform applied only to children, we can employ the difference-in-differences approach, where children constitute a treatment group and adults serve as a control group. The dataset covers 1841 observations. Aside from the treatment effect, we control for a number of personal characteristics using micro-level data (European Union Statistics on Income and Living Conditions). Using the zero-inflated negative binomial model, we found no significant effect from the abolition of user charges on doctor visits, suggesting either that user charges are ineffective in the Czech environment or that their value was set too low. On the contrary, personal income, the number of household members and gender have a significant effect. A number of robustness checks using restricted samples confirm the results. PMID:27422120

    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.

    The study examines spatial patterns of effects of high temperature extremes on cardiovascular mortality in the Czech Republic at a district level during 1994-2009. Daily baseline mortality for each district was determined using a single location-stratified generalized additive model. Mean relative deviations of mortality from the baseline were calculated on days exceeding the 90th percentile of mean daily temperature in summer, and they were correlated with selected demographic, socioeconomic, and physical-environmental variables for the districts. Groups of districts with similar characteristics were identified according to socioeconomic status and urbanization level in order to provide a more general picture than possible on the district level. We evaluated lagged patterns of excess mortality after hot spell occurrences in: (i) urban areas vs. predominantly rural areas; and (ii) regions with different overall socioeconomic level. Our findings suggest that climatic conditions, altitude, and urbanization generally affect the spatial distribution of districts with the highest excess cardiovascular mortality, while socioeconomic status did not show a significant effect in the analysis across the Czech Republic as a whole. Only within deprived populations, socioeconomic status played a relevant role as well. After taking into account lagged effects of temperature on excess mortality, we found that the effect of hot spells was significant in highly urbanized regions, while most excess deaths in rural districts may be attributed to harvesting effects.

    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.

    Tendencies in water regime resulting from land-use change represent an important subject for research and in the region of so called Black Triangle at the borders of Czech Republic, Germany and Poland urgent practical problem. Namely extensive deforestation in Czech hilly basins induced by acid rains, which appeared in seventies and eighties, requires attention. Discussions among professionals and public, sometimes having emotional character, took place after large floods on the rivers Odra and Morava in 1997 and in Vltava and Elbe river basins in August 2002. The influence of deforestation induced by acid rains in the Central Europe has been considered as important contribution to disastrous character of floods. Simulations of rainfall-runoff process in several catchments and experimental basins in two distinct headwater regions along German borders, with different extent of deforestation have been carried out using daily time series up to 40 years long. The outputs of two hydrological models of different structure have been compared in these investigations: - the conceptual model SAC-SMA - Sacramento soil moisture accounting - physically based 1- D model BROOK´90 The differences between observed and simulated discharge, which could show the tendencies in the runoff have been followed. They indicate increase of runoff after deforestation.

This study also examines male sex workers’ mental health problems in relation to their sexual identity or orientation. Material/Methods A sample of Czech male sex workers (N=40) were examined on a range of sexual and psychological variables using a quantitative survey administered face-to-face. The study employed locally validated versions of Beck’s Depression Inventory and Zung’s Self-Report Anxiety Scale. Results The results indicate that for homosexuals, working as a male sex worker is not related to any serious mental health problems. However, those identifying as heterosexual and bisexual more frequently reported symptoms of depression and bisexuals showed significantly more anxiety. Conclusions These findings suggest sexual identity is an important issue to consider when addressing the mental health needs of this population. PMID:25239091

    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.

  20. 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

    Overweight is often mentioned in causal relationship with various psychological problems and a lack of self-control. 438 randomly chosen subjects (selected from electoral registers or by random walk method)--men and women from Prague and the countryside--were divided according to their body weight into two groups, one with BMI equal or lower that 25, the other one with BMI higher than 25. 92.2 per cent of the subjects were overweight, 8 per cent had BMI higher than 30. Comparison of the two groups with lower and higher body weight based on a self-report questionnaire (GHQ, CAGE and some other items) showed differences between men and women. In men, with growing body weight the self-control in food intake decreased and problems related to lack of self-control increased significantly (smoking, problems with alcohol). On the contrary, women with overweight reported higher self-control in food intake (dieting) and had less problems with alcohol. The relationship between psychological problems (depression, anxiety) and overweight was not unequivocally proved. Men with higher body weight reported significantly less somatic problems in the GHQ. They also suffered comparatively less from depression and anxiety. The overweight women showed slightly more anxiety and significantly higher social dysfunction than women with normal body weight.

    2010-09-01

    Directive 2007/60/EC of the European Parliament and of the Council of 23 October 2007 on the assessment and management of flood risks (the Flood Risk Directive) signifies that flood risk analysis methods are gaining ground in EC Member States and, therefore, also in the Czech Republic (CR). Procedures of flood risk analysis have been developed in the Czech Republic since the catastrophic floods of 1997 in line with European and worldwide trends and have been tested and applied in hundreds of case studies to date. Currently, the Flood Risk Directive Guideline based on past experience with flood risk analysis applications is being processed. The aim of the paper is to present flood risk analysis procedures and specially developed techniques for the assembly of flood hazard, danger and flood risk maps. Methods related to flood risk management plans are briefly mentioned as well. The following particular problems are discussed in more detail: an application and extension of the "danger matrix" approach, the definition of residual danger, the formulation of efficiency criteria and preliminary multi-criteria flood risk assessment. These issues were tested in practical applications at pilot locations in the Czech Republic. Present experience provides evidence that the flood risk analysis methods used in the Czech Republic are in harmony with the requirements of the Flood Risk Directive. The proposed and applied methods are based primarily on existing available data such as flood extent maps, cadastral maps, the Register of Census Districts and Structures and others.

    Extraintestinal Escherichia coli infections are associated with extraintestinal pathogenic E. coli (ExPEC) strains. A total of 114 E. coli isolates were characterized regarding their antimicrobial resistance in a prospective study of 319 broilers from 12 slaughterhouses in the Czech Republic, a European Union member, during 2008. PCR-based assays to define ExPEC-associated traits were performed in resistant strains. Consumption of antimicrobial drugs by poultry in the Czech Republic was also analyzed. Antibiotic resistance was detected in 82% of isolates. Resistance to nalidixic acid and ciprofloxacin was predominant. Plasmid-mediated quinolone resistance genes, qnrB19 and qnrS1, were detected in 1 and 3 of 93 resistant isolates, respectively. Twenty-three percent of resistant isolates were considered as ExPEC. In total, 972 kg of flumequine, enrofloxacin, and difloxacin were used in poultry in the Czech Republic during 2008. High prevalence of broilers with ciprofloxacin-resistant E. coli isolates was linked to consumption of quinolones in poultry. Broilers may comprise an important vehicle for community-wide dissemination of fluoroquinolone-resistant E. coli and ExPEC. Withdrawal of fluoroquinolones from use in chicken production should be seriously considered in the Czech Republic and the European Union as well. PMID:23020862

    Active commuting (AC) to school represents a great opportunity to incorporate walking or cycling into adolescents’ everyday routine. The objective of the study was to describe changes in AC in Czech adolescents across a 10-year period in different built environments. Data from the 2001 and 2011 Czech Census of Population and Housing were used to examine the mode of transportation taken to school in 6236 adolescents. Changes in AC over time were analyzed for low and high walkable areas separately in two Czech regional cities, Olomouc and Hradec Králové. Between 2001 and 2011, the proportion of adolescents actively commuting to school decreased by 47%, from an absolute rate of 49.1% to 26%. The proportion of active commuters fell in low walkable areas by 61% and in high walkable areas by 39%. The results indicated that adolescents in 2011 were 2.7 times less (OR = 0.365, p < 0.001) likely to actively commute than in 2001. The AC behavior in Czech adolescents has a negative tendency to replicate travel-to-school patterns in adolescents previously described in more developed countries. The findings might serve as a recommendation for municipal policy. PMID:26501304

    2013-01-01

    Background Enterohemorrhagic Escherichia coli (EHEC) cause diarrhea-associated hemolytic uremic syndrome (D+ HUS) worldwide, but no systematic study of EHEC as the causative agents of HUS was performed in the Czech Republic. We analyzed stools of all patients with D+ HUS in the Czech Republic between 1998 and 2012 for evidence of EHEC infection. We determined virulence profiles, phenotypes, antimicrobial susceptibilities and phylogeny of the EHEC isolates. Methodology/Principal Findings Virulence loci were identified using PCR, phenotypes and antimicrobial susceptibilities were determined using standard procedures, and phylogeny was assessed using multilocus sequence typing. During the 15-year period, EHEC were isolated from stools of 39 (69.4%) of 56 patients. The strains belonged to serotypes [fliC types] O157:H7/NM[fliCH7] (50% of which were sorbitol-fermenting; SF), O26:H11/NM[fliCH11], O55:NM[fliCH7], O111:NM[fliCH8], O145:H28[fliCH28], O172:NM[fliCH25], and Orough:NM[fliCH25]. O26:H11/NM[fliCH11] was the most common serotype associated with HUS (41% isolates). Five stx genotypes were identified, the most frequent being stx2a (71.1% isolates). Most strains contained EHEC-hlyA encoding EHEC hemolysin, and a subset (all SF O157:NM and one O157:H7) harbored cdt-V encoding cytolethal distending toxin. espPα encoding serine protease EspPα was found in EHEC O157:H7, O26:H11/NM, and O145:H28, whereas O172:NM and Orough:NM strains contained espPγ. All isolates contained eae encoding adhesin intimin, which belonged to subtypes β (O26), γ (O55, O145, O157), γ2/θ (O111), and ε (O172, Orough). Loci encoding other adhesins (efa1, lpfAO26, lpfAO157OI-141, lpfAO157OI-154, iha) were usually associated with particular serotypes. Phylogenetic analysis demonstrated nine sequence types (STs) which correlated with serotypes. Of these, two STs (ST660 and ST1595) were not found in HUS-associated EHEC before. Conclusions/Significance EHEC strains, including O157:H7 and non

    The complex analysis of the pedigree records of Czech Landrace (CLA), Czech Large White-dam line (CLWd), Czech Large White-sire line (CLWs), Duroc (DC), and Pietrain (PN) was performed to determine trends of genetic diversity (GD), and to find the main sources of the GD loss. The total size of the pedigree was 132,365, 391,151, 32,913, 13,299, and 7,160 animals in CLA, CLWd, CLWs, DC, and PN, respectively. Animals born in the years 2011 through 2013 were assumed as the reference population. The average pedigree completeness index for one generation back was 95.9%, 97.4%, 91.2%, 89.8%, and 94.2% for appropriate breeds. Number of ancestors explaining 100% of gene pool was 186, 373, 125, 157, and 37 in CLA, CLWd, CLWs, DC, and PN, respectively. The relative proportion of inbred animals (58%, 58%, 54%, 47%, and 25%), the average inbreeding (2.7%, 1.4%, 2.5%, 3.6%, and 1.3%) and the average co-ancestry (3.1%, 1.6%, 3.3%, 4.2%, and 3.3%) were found over the past decade in analysed breeds. The expected inbreeding under random mating increased during the last 10 years in CLWs and PN and varied from 1.27% to 3.2%. The effective population size computed on the basis of inbreeding was 76, 74, 50, 35, and 83 in 2012 in CLA, CLWd, CLWs, DC, and PN, respectively. The shortest generation interval (1.45) was observed for CLWd in sire to son selection pathway. The longest generation interval obtained PN (1.95) in sire to daughter pathway. The average relative GD loss within last generation interval was 7.05%, 4.70%, 9.81%, 7.47%, and 10.46%, respectively. The relative proportion of GD loss due to genetic drift on total GD loss was 85.04%, 84.51%, 89.46%, 86.19%, and 83.68% in CLA, CLWd, CLWs, DC, and PN, respectively. All breeds were characterized by a high proportion of inbred animals, but the average inbreeding was low. The most vulnerable breeds to loss of GD are DC and PN. Therefore, a breeding program should be more oriented to prevent the increase of GD loss in these breeds

    In previous studies the spatial and temporal evolution of drought events in the Czech Republic were extensively analyzed by comparing results from the most advanced drought indices (e.g. the SPI and SPEI), which take into account the role of antecedent conditions in quantifying drought severity. In the present study, the Standardized Precipitation Evapotranspiration Index (SPEI) was adopted to assess and project drought characteristics in the Czech Republic based on the regional climate model ALADIN-Climate/CZ simulated data. The simulations were conducted at high resolution (10km) for the current (1961-2000) and two future climates (2021-2050 and 2071-2100). First, the observed data of air temperature and precipitation totals was transferred into a regular grid of ALADIN-Climate/CZ model. The bias correction was applied on the scenario runs. The bias correction method is based on variable correction using individual percentiles whose relationship is derived from observations and control RCM simulation. The SPEI was calculated based on observed monthly data of mean temperature and precipitation totals for the period 1961-1990, as reference period, and for the periods 2021-2050 and 2071-2100, as future climates under A1B SRES scenario. The SPEI were calculated with various lags, 1, 3, 6, 12 and 24 months because the drought at these time scales is relevant for agricultural, hydrological and socio-economic impact, respectively. The study refers at the warm season of the year (April to September). As in the case of observational study, we have identified three climatically homogeneous regions, corresponding to the altitudes below 400 m, between 401 and 700 m and, above 700 m. For these three regions the frequency distribution of the SPEI values in 7 classes of drought category (%) were calculated based on grid point data falling in each region, both for the observed data and scenario runs. The paper presents the projected changes in frequency distribution of SPEI at

    2013-09-01

    In this paper, quantitative precipitation forecasts (QPF) are evaluated using several verification techniques and analysis of the results from these techniques. The forecasts were produced by two limited-area numerical weather prediction models: the ALADIN-CZ model operated by the Czech Hydro-Meteorological Institute (CHMI) and the COSMO model operated by the German Weather Service (DWD). Each model was run using two horizontal resolutions over the domain covering the Czech Republic. The ALADIN-CZ model outputs were obtained using resolutions of approximately 9 km and 4.7 km, and the COSMO model outputs were obtained using resolutions of approximately 7 km and 2.8 km. The forecast quality is studied for the flash flood period that occurred in June and July of 2009, when convective rainfalls with durations of 1 to 3 h and a return period of more than 100 years caused devastating floods in many Czech localities. The radar-based rainfalls used to verify the forecasts were produced by the CHMI operational product MERGE, which merges radar-derived rainfalls with the rainfalls that are measured by ground rain gauges. A series of 56 consecutive forecasts of 3-h rainfalls were verified using traditional and spatial verification techniques, and the results from these analyses were compared. The verification was performed using traditional verification scores based on a contingency table, spatial verification by the fractions skill score (FSS) and the SAL (structure-amplitude-location) technique. The FSS represents a fuzzy verification technique and compares the fractional coverage of precipitation grids over a threshold in spatial windows around the observations and forecasts. The SAL is a spatial object-oriented verification technique used to evaluate the structure, amplitude, and location of a precipitation field. The quality of QPF depends strongly on the scale of convective precipitation, and all models provide good forecast quality for extended rainfall systems. The

    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

    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

    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. PMID:25763029

    Astroviruses are a major cause of gastroenteritis in humans and animals. Recently, novel groups of astroviruses were identified in apparently healthy insectivorous bats. We report the detection of diverse novel astrovirus sequences in nine different European bat species: Eptesicus serotinus, Hypsugo savii, Myotis emarginatus, M. mystacinus, Nyctalus noctula, Pipistrellus nathusii or P. pygmaeus, P. pipistrellus, Vespertilio murinus, and Rhinolophus hipposideros. In six bat species, astrovirus sequences were detected for the first time. One astrovirus strain detected in R. hipposideros clustered phylogenetically with Chinese astrovirus strains originating from bats of the families Rhinolophidae and Hipposideridae. All other Czech astrovirus sequences from vesper bats formed, together with one Hungarian sequence, a separate monophyletic lineage within the bat astrovirus group. These findings provide new insights into the molecular epidemiology, ecology, and prevalence of astroviruses in European bat populations. PMID:26273815

    Nitrogen dioxide (NO₂) is a toxic gas, a product of combustion in malfunctioning ice-resurfacing machines. NO₂ poisoning is rare but potentially lethal. The authors report a case of mass NO₂ poisoning involving 15 amateur ice hockey players in the Czech Republic. All players were treated in the Department of Respiratory Diseases at Brno University Hospital in November 2010 - three as inpatients because they developed pneumonitis. All patients were followed-up until November 2011. Complete recovery in all but one patient was achieved by December 2010. None of the 15 patients developed asthma-like disease or chronic cough. Corticosteroids appeared to be useful in treatment. Electric-powered ice-resurfacing machines are preferable in indoor ice skating arenas. PMID:24032121

    In 1995 and 1996, the shedding of Toxoplasma gondii oocysts was monitored in the faeces of Felidae in six zoos in the Czech Republic. In all, 2287 samples of faeces from 19 species of Felidae were examined. In Ostrava Zoo, four episodes of shedding of Toxoplasma-like oocysts were identified, using a flotation examination, in a pair of wild cats (Felis silvestris), six episodes in a wild cat held separately, and three episodes in a pair of Amur leopard cats (F. euptilurus). After the passage of sporulated oocysts through laboratory mice, T. gondii was confirmed in the pair of wild cats (three episodes), in the wild cat held separately (three episodes) and in the pair of Amur leopard cats (one episode). In Jihlava Zoo, one episode of shedding of T. gondii oocyst was identified in Geoffroy's cat (Oncifelis geoffroyi) using flotation and isolation examination. The possible sources of toxoplasmosis of the Felidae in zoos are discussed. PMID:9493305

    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.

    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. PMID:25004940

    Long-term observations of total ozone (TOZ) and vertical ozone profiles, the basic parameters of the ozone layer, have been performed at the Solar and Ozone Observatory (SOO) Hradec Kralove and at the Aerological Department (AD) Praha of the Czech Hydrometeorological Institute (CHMI) since 1961 and 1992 respectively. The Dobson and Brewer spectrophotometers regularly calibrated towards the international references and electro-chemical ECC ozone sondes are used for the measurements. The observations contribute to the global GAW and NDACC ozone monitoring systems. Up to now analyses of the data give the basic findings given bellow and documented in the presentation. Some of them have important implication to the international ozone monitoring infrastructure, as well. - The decrease of TOZ by about 5-7 % in the winter-spring months towards the pre ozone-hole period have occurred since the mid eighties. This is in good agreement by the magnitude and time with depletion of the ozone layer due to chemical destruction of ozone in the NH mid-latitudes. - Significant depletion 3-5 % of TOZ has been identified also in the summer season since the early nineties. As this can not be attributed to the man-made chemical processes a change in the UT/LS dynamics over Central Europe is the most probable reason. - Aerological measurements taken at AD show that the summer reduction of TOZ very well coincides with a change of UT/LS temperature that persists for about two decades over the Czech territory. Therefore it has a long-term character that can be regarded as a climate shift in UT/LS and need to be further investigated. - 15 years of unique simultaneous Dobson/Brewer observations of TOZ performed at SOO show systematic seasonal deviations between both data sets that exceed instrumental accuracy of measurements. The differences are mostly caused by different wavelengths and their ozone absorption coefficients used by both instruments. As the Brewer observations are being

    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.

    Fifty-two ostracod taxa were identified from two sediment cores collected from the early Badenian Židlochovice stratotype. Ostracod assemblages were analyzed with a focus on taxonomy, paleoecology, distribution of taxa along the sediment cores, quantification of valve/carapace ratios, and species richness by Simpson's Reciprocal Index. The changes in ostracod assemblages identified in these cores reflect a shallowing of the marine water-depth from circalittoral/epibathyal to shallow infralittoral, and an increase in the sedimentation rate upwards through time. A comparison of all Badenian ostracod assemblages in the Carpathian Foredeep indicates a high proportion of deep-water ostracod species in Židlochovice and its surroundings, suggesting that the deepest part of the Carpathian Foredeep was probably situated in this part of the Czech Republic.

    The 4 casein loci were evaluated as haplotypes in 2 dairy goat breeds kept in the Czech Republic. Analysis of 41 White Shorthaired (WSH) trio families and 44 Brown Shorthaired (BSH) trio families revealed 14 and 20 haplotypes, respectively. Various genomic techniques were used to type the casein loci. Twenty-two different combinations of these alleles (casein haplotypes, in the order CSN1S1-CSN2-CSN1S2-CSN3) were found. Only 5 haplotypes in the WSH breed and 6 haplotypes in the BSH breed occurred at frequencies >0.05. For the WSH breed, the most common haplotype was FCFB (0.260), whereas for the BSH breed, the most common haplotype was FCFA (0.217). The information on the haplotype variability in both breeds could be used in breeding programs aimed at preserving biodiversity or selecting animals for specific protein production and cheesemaking.

    The aim of this study is to develop the spatial model of summer precipitation over the Czech Republic using auxiliary geographical variables in order to produce gridded data needed for various applications. Daily precipitation data from 203 stations for the period 1971 - 2003 are used. Model is performed at different time steps (year, ten-years, and entire period). Considering that models performed at different time steps can vary significantly, it was necessary to verify two assumptions before the development of spatial prediction: (1) whether geographical variables control significantly the spatial distribution of summer precipitation over the Czech Republic; (2) and whether the effects of significant geographical variables (model parameters) do not vary significantly in time. Various candidate geographical predictors are evaluated in the stepwise regression models for summer precipitation: (1) a set of omnidirectional parameters of the elevation characterizing an area of 3 km x 3 km around meteorological stations, (2) various cross products calculated between geographical coordinates and elevation or topographic parameters, (3) slope and four facets of slope aspect which characterize the orographic regimes over the Czech Republic, (4) land cover parameters describing areas of about 10 km by 10 km around meteorological stations and (5) geographical coordinates. The orographic parameters are derived from the 1 km resolution digital elevation model (DEM), while the land cover parameters are derived from the 1 km resolution CORINE (Coordination of information on the environment) land cover data. To assure stability of the regression equations and comparability of regression models in time, both orthogonally rotated Principal Component Analysis (PCA) and frequency of significant predictors - selected using stepwise regression at each time step - are used to select identical significant independent variables for various time steps.

    By comparing five ecosystem types in the Czech Republic over several years, we recorded the highest carbon sequestration potential in an evergreen Norway spruce forest (100%) and an agroecosystem (65%), followed by European beech forest (25%) and a wetland ecosystem (20%). Because of a massive ecosystem respiration, the final carbon gain of the grassland was negative. Climate was shown to be an important factor of carbon uptake by ecosystems: by varying the growing season length (a 22-d longer season in 2005 than in 2007 increased carbon sink by 13%) or by the effect of short- term synoptic situations (e.g. summer hot and dry days reduced net carbon storage by 58% relative to hot and wet days). Carbon uptake is strongly affected by the ontogeny and a production strategy which is demonstrated by the comparison of seasonal course of carbon uptake between coniferous (Norway spruce) and deciduous (European beech) stands.

    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 prebreeding 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. PMID:21395201

    Land adjustment in Czech Republic is the instrument of landscape transformation, ecological stability consolidation, real property ownership restoration and land register arrangement. This instrument has been based in our legal order since 1990, and it is still actively used. Through this process it is possible to project new aquiculturing measurements, erosion control measurements, new components of ecological network or new field roads, which are the most common measurement of all. Here will be presented the inventory of projected and realized measurements of all mentioned types in several cadastral territories. Also there will be mentioned their impact on ecological stability, flood management or erosion control.

    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

    The objective of this study was to estimate the genetic parameters, genetic trends and breeding values using linear model (LM) and threshold model (TM) for the development of hip dysplasia (HD) in Labrador Retrievers in the Czech Republic (n = 3151). The right and left hip joints were evaluated separately using the Fédération Cynologique Internationale scoring system. Four linear and four TMs were tested for the correct estimation of genetic parameters. All the tested models utilized fixed effects of sex, assessor, year of birth, regression of age at evaluation, random direct genetic effects and the effect of the animals' permanent environments. The models differed in the inclusion of the following effects: fixed effects of regression of inbreeding coefficient, random maternal effect and random effect of the maternal permanent environment. Compared to the TM, the LM provided lower coefficients of direct (0.25-0.29 versus 0.26-0.35) and maternal heritability (0.01-0.02 versus 0.03-0.05), repeatability (0.76-0.77 versus 0.78-0.83) and of the correlation between direct and maternal effects (-0.55 to -0.21 versus -0.80 to -0.27). In the tested models, no statistical significance was found for fixed regression of inbreeding coefficients or for the random effect of the permanent maternal environment. In spite of the similarity of the LM and TM results, the TM is recommended as the more suitable model for estimating genetic parameters and subsequent breeding values for HD in Labrador Retrievers in the Czech Republic.

    This article presents major epidemiologic features of tick-borne encephalitis (TBE) in the Czech Republic, using data of laboratory-confirmed cases since 1970. A total of 17,053 cases of TBE were reported in the Czech Republic (population 10 million) in 1970-2008. The data show several important features. First, the pattern of TBE incidence changed over time. Until the end of the 1970s, TBE was characterized by periods of alternately higher and lower incidence (between 180 and 595 cases per year); the 1980s were a period of low incidence with minimum variability; since the beginning of the 1990 s, there has been a steep rise in incidence, with marked year-to-year variation (e.g., 745 cases were registered in 1995, and a maximum of 1029 cases were registered in 2006). Second, the age distribution of TBE incidence has changed. Until the end of 1990 s, incidence peaked among those 15-19 years of age, with a gradual decline with age. In the 2000s, however, TBE incidence has been rising in those aged 60-64 years, with a sharp decline in those older than 65 years. Third, the seasonal pattern of TBE has changed markedly over time. In the earlier period, incidence had a clear peak in July/August; since the 1990 s, more cases have occurred in earlier and later months of the year. The proportion of cases occurring in April, May, October, and November increased from 9% in the 1970s to 23% in 2000-2008. Fourth, the geographical distribution of TBE also changed over time, with TBE increasingly occurring in the mountainous districts at higher altitudes. These changes in incidence patterns appear to be linked with changes in climatic and meteorological conditions. The link between climate change and TBE incidence is plausible, since TBE is a recreation-related infection associated with outdoor activities, and since climatic changes affect the life cycle of the vector.

    Aim: CYP2C8 represents 7% of the hepatic cytochrome system and metabolizes around 5% of drugs in phase I processes. It also plays a significant role in metabolism of endogenous compounds. More than 20 single-nucleotide polymorphisms (SNPs) have been noted, mainly in exons 3, 5, and 8. The most studied SNPs may lead to decreased enzyme activity and may have impact on drug metabolism. Variant alleles are called CYP2C8*2 (I269F), CYP2C8*3 (R139K, K399R), and CYP2C8*4(I264M). Our aim was to investigate the frequency of major functional SNPs among the Czech population. Material and methods: DNA was isolated from whole blood of 161 healthy, young, and unrelated subjects (94 men and 67 women, aged from 23 to 28 years). The genotypes of polymorphic positions CYP2C8*2, CYP2C8*3 (G416A, A1196G), and CYP2C8*4 were determined by polymerase chain reaction–restriction fragment length polymorphism. Results and conclusion: Observed allele frequencies were 10.9%, 5.9%, and 0.3% for the alleles CYP2C8*3, CYP2C8*4, and CYP2C8*2, respectively. Both CYP2C8*3 (G416A, A1196G) alleles have been found in complete linkage disequilibrium. The allele distribution complies well with Hardy–Weinberg equilibrium. Allele frequencies of functionally important CYP2C8 variants in the Czech population are similar to that of other Caucasian populations. PMID:22313047

    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.

  14. 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.

    Over the recent years, the incidence of obesity is continuously rising. A research conducted in 2008-2009 on a representative sample of Czech population (n = 2,058) suggests that 23% of adult population of the Czech Republic are obese and 34% are overweight. This represents an increase of 5% in the number of obese people (17% vs. 22%), while the number of overweight remains practically the same (35% vs. 34%). A more significant shift in female waist circumference compared to male has also been shown. The incidence of hypertension in the evaluated sample was more than a two-fold higher in obese participants (48% vs. 21%) and as much as 3-fold higher in type 2 diabetes mellitus (7% vs. 20%). The risk of body weight increase is the highest between 50th and 59th year of age, where hypertension and diabetes are the most frequently diagnosed. The risk of obesity in adulthood is mostly carried over from childhood and more than 3/4 (77%) of those, who were overweight or obese as children, are in these categories as adults. Quality of life and satisfaction with own health is more related to BMI than age. Even though body weigh is increasing with the same amplitude in sportsman and physically active people, they are reaching lower final BMI due to their lower starting body weight. It is clear that physically active lifestyle in younger age is the best predictor of lower BMI in adult life. Consumption of secondary processed meat and lower consumption of fruit and vegetables are important factors in adulthood. PMID:21105446

    Background White-nose syndrome is a disease of hibernating insectivorous bats associated with the fungus Geomyces destructans. It first appeared in North America in 2006, where over a million bats died since then. In Europe, G. destructans was first identified in France in 2009. Its distribution, infection dynamics, and effects on hibernating bats in Europe are largely unknown. Methodology/Principal Findings We screened hibernacula in the Czech Republic and Slovakia for the presence of the fungus during the winter seasons of 2008/2009 and 2009/2010. In winter 2009/2010, we found infected bats in 76 out of 98 surveyed sites, in which the majority had been previously negative. A photographic record of over 6000 hibernating bats, taken since 1994, revealed bats with fungal growths since 1995; however, the incidence of such bats increased in Myotis myotis from 2% in 2007 to 14% by 2010. Microscopic, cultivation and molecular genetic evaluations confirmed the identity of the recently sampled fungus as G. destructans, and demonstrated its continuous distribution in the studied area. At the end of the hibernation season we recorded pathologic changes in the skin of the affected bats, from which the fungus was isolated. We registered no mass mortality caused by the fungus, and the recorded population decline in the last two years of the most affected species, M. myotis, is within the population trend prediction interval. Conclusions/Significance G. destructans was found to be widespread in the Czech Republic and Slovakia, with an epizootic incidence in bats during the most recent years. Further development of the situation urgently requires a detailed pan-European monitoring scheme. PMID:21079781

    Spinocerebellar ataxias (SCAs) are a heterogeneous group of neurodegenerative disorders currently associated with 27 genes. The most frequent types are caused by expansions in coding CAG repeats. The frequency of SCA subtypes varies among populations. We examined the occurrence of rare SCAs, SCA8, SCA12, SCA17 and dentatorubro-pallidoluysian atrophy (DRPLA), in the Czech population from where the data were missing. We analyzed causal gene expansions in 515 familial and sporadic ataxic patients negatively tested for SCA1-3 and SCA6-7. Pathogenic SCA8 and SCA17 expansions were identified in eight and five patients, respectively. Tay-Sachs disease was later diagnosed in one patient with an SCA8 expansion and the diagnosis of multiple sclerosis (MS) was suspected in two other patients with SCA8 expansions. These findings are probably coincidental, although the participation of SCA8 expansions in the susceptibility to MS and disease progression cannot be fully excluded. None of the patients had pathogenic SCA12 or DRPLA expansions. However, three patients had intermediate SCA12 alleles out of the normal range with 36 and 43 CAGs. Amyotrophic lateral sclerosis (ALS) was probable in the patient with 43 CAGs. This coincidence is remarkable, especially in the context with the recently identified predisposing role of longer SCA2 alleles in ALS. Five families with SCA17 represent a significant portion of ataxic patients and this should be reflected in the diagnostics of SCAs in the Czech population. SCA8 expansions must be considered after careful clinical evaluation. PMID:22872568

    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

    Internist Bohumil Eiselt belongs to eminent personalities of the Prague Medical Faculty. Since the summer semester in 1861, he purposefully and systematically persuaded the Czech as the teaching language at the Prague Medical Faculty. In 1871, his clinic was recognized as the first Czech clinic of the not yet divided Prague Medical School. In 1881, he managed to get the largest clinic of internal medicine in the general teaching hospital which, after the activation in 1883, was transferred at the Czech Medical School. It ensured the Czech medics good conditions for learning internal medicine. Bohumil Eiselt stood at the cradle of the Czech Medical Association and the Journal of Czech Physicians, founded in 1862, whose introduction was necessary for the development of professional medical Czech. The same importance had his publishing the edited compendium Professional pathology and therapy in the years 1878-1889 and organizing the first congresses of Czech medical doctors. PMID:22292345

    An international project network consisting of five receivers for sampling LF and VLF radio signals has been going on to record the data in Europe from different transmission stations around the World. One of them was established in Resadiye, Turkey, located just on the North Anatolian Fault Zone. The receiver works in VLF (16.4, 21.75, 37.5 and 45.9 kHz) and LF (153, 180, 183, 216 and 270 kHz) bands monitoring ten frequencies with one minute sampling interval. An earthquake of Mw = 4.9 took place 225 km away from the VLF/LF station at the eastern tip of the Erzincan basin at 4 km depth on July 30, 2009. We observed some anomalies on the radio signals (37.5 and 153 kHz) that initiated about 7 days before the earthquake and disappeared soon after the earthquake. We attribute this anomaly to the Mw=4.9 earthquake as a seismo-electromagnetic precursor. The radio anomaly that appeared 7 days before the occurrence of the 2009 Erzincan earthquake is in good agreement with other results indicating precursory anomalies in the project network mostly observed in seismically active countries such as Italy and Greece. Several data processing stages were applied to the data. Firstly, we processed the time series of the radio signals to understand how the frequency content of the anomaly differs from that of the normal trend. For this purpose we selected two time windows; one covering the anomaly period and the other spanning a normal period. The selected time window length was a 6 day. The sampling interval and the length of the time window limit the observed spectra from 120 seconds to six days. We identified a significant bias (drop) for the signal energy of the anomaly period at the whole frequency band. Secondly, in order to clearly depict the anomaly we estimated the daily Rayleigh Energy of the calculated spectra following the Parseval's theorem. We initiated the estimations well before the anomaly period. Such calculations gave an obvious sign for the impending event. Thirdly, we constructed a spectrogram including the whole frequency band of the data from fortnight before the earthquake to a week after the earthquake. The strongest anomaly in the spectrogram was identified for the periods larger than 60 hours. In earthquake prediction studies it is crucial to understand the source of the anomaly. Since the sources of the anomaly we are interested in are the earthquakes we tried to derive information on the properties of the earthquake that generated our anomaly in the radio signals. Within this frame, we analyzed the broadband data at several local seismic stations that recorded the event and estimated source parameters such as centroid moment tensor, source radius and stress drop. Our analysis shows that the event was a shallow one showing predominantly normal faulting mechanism and was associated with extremely high stress drop with an average value of about 250 bars.

    On July 20, 1969, the human race accomplished its single greatest technological achievement of all time when a human first set foot on another celestial body. Six hours after landing at 4:17 p.m. Eastern Standard Time (with less than thirty seconds of fuel remaining), Neil A. Armstrong took the "small step" into our greater future when he stepped off the Lunar Module, named Eagle, onto the surface of the Moon, from which he could look up and see Earth in the heavens as no one had done before him. He was shortly joined by Edwin "Buzz" Aldrin, and the two astronauts spent twenty-one hours on the lunar surface and returned forty-six pounds of lunar rocks. After their historic walks on the Moon, they successfully docked with Michael Collins, patiently orbiting the cold but no longer lifeless Moon alone in the Command module Columbia. This CR-ROM is intended as a collection of hard to find technical data and other interesting information about the Apollo 11 mission, as well as the apollo program in general. It includes basic overviews, such as a retrospective analysis, an annotated bibliography, and history of the lunar-orbit rendezvous concept. It also contains technical data, such as mission operations reports, press kits, and news references for all of the Apollo missions, the Apollo spacecraft, and the Saturn V launch vehicle. Rounding out this CD-ROM are extensive histories of the lunar Orbiter program (the robotic predecessor to Apollo, biographies of the Apollo astronauts and other key individuals, and interesting audio-visual materials, such as video and audio clips, photo galleries, and blueprint-like diagrams of the Apollo spacecraft.

    These proceedings document a number of aspects of a big science facility and its impact on science, on technology, and on the continuing program of a major US research institution. The Zero Gradient Synchrotron (ZGS) was a 12.5 GeV weak focusing proton accelerator that operated at Argonne for fifteen years--from 1964 to 1979. It was a major user facility which led to new close links between the Laboratory and university groups: in the research program; in the choice of experiments to be carried out; in the design and construction of beams and detectors; and even in the Laboratory management. For Argonne, it marked a major move from being a Laboratory dominated by nuclear reactor development to one with a stronger basic research orientation. The present meeting covered the progress in accelerator science, in the applications of technology pioneered or developed by people working at the ZGS, as well as in physics research and detector construction. At this time, when the future of the US research programs in science is being questioned as a result of the ending of the Cold War and plans to balance the Federal budget, the specific place of the National Laboratories in the spectrum of research activities is under particular examination. This Symposium highlights one case history of a major science program that was completed more than a decade ago--so that the further developments of both the science and the technology can be seen in some perspective. The subsequent activities of the people who had worked in the ZGS program as well as the redeployment of the ZGS facilities were addressed. Selected papers are indexed separately for inclusion in the Energy Science and Technology Database.

    The Biomolecule Sequencer is a Commercial Off-The-Shelf device developed by Oxford Nanopore Technologies and implements a method of DNA sequencing unlike any other current sequencers. The device measures changes in electrical current through a nanopore depending on the sequence of the DNA strand that is passing through it. Since the technology is built on nanometer-scale ion pores, the hardware itself is exceptionally small (3 x 1 x 58 inches), lightweight (less than 120 grams with USB cable), and powered only by a USB connection. The sequencing device is permanent, while the flow cells, to which the samples are added, are periodically replaced. The goal of our upcoming technology demonstration on ISS is to provide evidence that DNA sequencing in space is possible, which holds the exciting potential to enable the identification of microorganisms, monitor changes in microbes and humans in response to spaceflight, and possibly aid in the detection of DNA-based life elsewhere in the universe.

    Since human infection by a novel influenza virus A H1N1 of swine origin was reported in April 2009, the virus has spread worldwide causing a pandemic. In the Southern Hemisphere, the first pandemic wave has taken place, coinciding with Austral Winter. In the Northern Hemisphere, transmission has been sustained under the basal level of epidemic until the first weeks of October, when incidence rates have risen up to the pidemic level in some countries, including Spain. This work reviews the differential characteristics of this novel virus in terms of pathogenicity, clinical syndrome and epidemiology, as well as the diagnostic, prophylactic and therapeutic procedures available; information we consider relevant to minimize the impact of this new pandemic in our area.

    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

    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).

    Background Previous studies have shown that deprived neighbourhoods have higher cardiovascular mortality and morbidity rates. Inequalities in the distribution of behaviour related risk factors are one possible explanation for this trend. In our study, we examined the association between cardiovascular risk factors and neighbourhood characteristics. To assess the consistency of associations the design is cross-national with data from nine industrial towns from the Czech Republic and Germany. Methods We combined datasets from two population based studies, one in Germany ('Heinz Nixdorf Recall (HNR) Study'), and one in the Czech Republic ('Health, Alcohol and Psychosocial Factors in Eastern Europe (HAPIEE) Study'). Participation rates were 56% in the HNR and 55% in the HAPIEE study. The subsample for this particular analysis consists of 11,554 men and women from nine German and Czech towns. Census based information on social characteristics of 326 neighbourhoods were collected from local administrative authorities. We used unemployment rate and overcrowding as area-level markers of socioeconomic status (SES). The cardiovascular risk factors obesity, hypertension, smoking and physical inactivity were used as response variables. Regression models were complemented by individual-level social status (education) and relevant covariates. Results Smoking, obesity and low physical activity were more common in deprived neighbourhoods in Germany, even when personal characteristics including individual education were controlled for. For hypertension associations were weak. In the Czech Republic associations were observed for smoking and physical inactivity, but not for obesity and hypertension when individual-level covariates were adjusted for. The strongest association was found for smoking in both countries: in the fully adjusted model the odds ratio for 'high unemployment rate' was 1.30 [95% CI 1.02–1.66] in the Czech Republic and 1.60 [95% CI 1.29–1.98] in Germany

    Pancreatic ductal adenocarcinoma (PDAC) has the worst prognosis among common solid cancer diagnoses. It has been shown that up to 10% of PDAC cases have a familial component. Characterization of PDAC-susceptibility genes could reveal high-risk individuals and patients that may benefit from tailored therapy. Hereditary mutations in PALB2 (Partner and Localizer of BRCA2) gene has been shown to predispose, namely to PDAC and breast cancers; however, frequencies of mutations vary among distinct geographical populations. Using the combination of sequencing, high-resolution melting and multiplex ligation-dependent probe amplification analyses, we screened the entire PALB2 gene in 152 unselected Czech PDAC patients. Truncating mutations were identified in three (2.0%) patients. Genotyping of found PALB2 variants in 1226 control samples revealed one carrier of PALB2 truncating variant (0.08%; P = 0.005). The mean age at PDAC diagnosis was significantly lower among PALB2 mutation carriers (51 years) than in non-carriers (63 years; P = 0.016). Only one patient carrying germline PALB2 mutation had a positive family breast cancer history. Our results indicate that hereditary PALB2 mutation represents clinically considerable genetic factor increasing PDAC susceptibility in our population and that analysis of PALB2 should be considered not only in PDAC patients with familial history of breast or pancreatic cancers but also in younger PDAC patients without family cancer history.

Echinococcus multilocularis was found in the following regions: South Bohemian (districts Jindrichův Hradec, Ceský Krumlov, Prachatice and Strakonice), Central Bohemian (Benesov district) and North Bohemian (district Teplice and Chomutov). There were 87 positive (10.6%) foxes in 56 places (16%). In some areas of the South Bohemian region examinations of foxes were repeated. It was found that there are places where the prevalence of E. multilocularis varied between 28.6 and 75% (mean 53.7%) but also areas which were repeatedly negative. In 1996 after one-week intervals foxes from the Prachatice district (South Bohemian region) were sent for parasitological examination. During different months of the year the prevalence of E. multilocularis varied between 2.6 and 33.3%. A similar investigation was made during May to October 1996 (except September) also in the district of Ceský Krumlov (South Bohemian region). Tapeworms were found in 7.14 to 66.7% of foxes.

    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.

    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.

    Kabuki syndrome (KS) is a dominantly inherited disorder mainly due to de novo pathogenic variation in KMT2D or KDM6A genes. Initially, a representative cohort of 14 Czech cases with clinical features suggestive of KS was analyzed by experienced clinical geneticists in collaboration with other specialties, and observed disease features were evaluated according to the 'MLL2-Kabuki score' defined by Makrythanasis et al. Subsequently, the aforementioned genes were Sanger sequenced and copy number variation analysis was performed by MLPA, followed by genome-wide array CGH testing. Pathogenic variants in KMT2D resulting in protein truncation in 43% (6/14; of which 3 are novel) of all cases were detected, while analysis of KDM6A was negative. MLPA analysis was negative in all instances. One female patient bears a 6.6 Mb duplication of the Xp21.2-Xp21.3 region that is probably disease causing. Subjective KS phenotyping identified predictive clinical features associated with the presence of a pathogenic variant in KMT2D. We provide additional evidence that this scoring approach fosters prioritization of patients prior to KMT2D sequencing. We conclude that KMT2D sequencing followed by array CGH is a diagnostic strategy with the highest diagnostic yield. PMID:26841933

    The growing numbers of stray dogs and cats have posed serious public-health, socioeconomic, political and animal-welfare problems in many EU countries. Stray animal population control is a complex issue and there are no easy solutions. Recognising the importance of the issue the European Commission has, since 2007, actively contributed to the elaboration of the first global welfare standards for the control of dog populations in the framework of the World Organisation for Animal Health (OIE). Problem-solving approaches vary in different countries as there is no common European Community legislation dealing with stray animal control. In this paper the authors describe the characteristics of the stray dog and cat problem in general and focus on existing European legislation. A comparative overview of policies and measures in place in the Czech Republic and in Italy is made to observe the differences between the two countries and understand the different needs in each, considering their historical and social differences (i.e. a post-communist eastern country vs a western country and founder member of what is now the European Union).

    Broadband recordings of 88 seismic stations distributed in the Bohemian Massif, Czech Republic, and covering the time period of up to 12 years were processed by a cross-correlation technique. All correlograms were analyzed by a novel approach to get both group and phase dispersion of Rayleigh and Love waves. Individual dispersion curves were averaged in five distinct geological units which constitute the Bohemian Massif (Saxothuringian, Teplá-Barrandean, Sudetes, Moravo-Silesian, and Moldanubian). Estimated error of the averaged dispersion curves are by an order smaller than the inherent variability due to the 3D distribution of seismic velocities within the units. The averaged dispersion data were inverted for 1D layered velocity models including their uncertainty, which are characteristic for each of the geological unit. We found that, overall, the differences between the inverted velocity models are of similar order as the variability inside the geological units, suggesting that the geological specification of the units is not fully reflected into the S-wave propagation velocities on a regional scale. Nevertheless, careful treatment of the dispersion data allowed us to identify some robust characteristics of the area. The vp to vs ratio is anomalously low (~1.6) for all the units. The Moldanubian is the most rigid and most homogeneous part of the Bohemian Massif. Middle crust in the depth range of ~3-15 km is relatively homogeneous across the investigated region, while both uppermost horizon (0-3 km) and lower crust (>15 km) exhibit lower degree of homogeneity.

    To reconstruct the geomorphic imprint of the anthropogenic and natural environmental changes in the Late Holocene, we studied the alluvial record of the Bečva River floodplain (Outer Western Carpathians, Czech Republic). Coring, geophysical sounding and lithological analysis of floodplain deposits supported by AMS (accelerator mass spectrometry) dating enabled the establishment of the primary evolutionary stages of Late Holocene floodplain evolution. During the Late Atlantic and Early Subboreal periods, gravel aggradation and braided environments occurred in the studied floodplain. The Late Subboreal and Early Subatlantic are characterised by overbank sedimentation, and the Middle Subatlantic is marked by the recurrence of gravel aggradation. A major incision phase took place during the Mediaeval Warm Period. The onset of overbank sedimentation in the 15th century correlated with ongoing deforestation of the lower parts of catchment, and colonisation of the mountain ridges during the 16th-17th centuries further accelerated this process. During the 20th century, reforestation of mountains and river-channel training resulted in a significant incision phase. Our data suggest that climate fluctuations were major driving factors for the morpho-sedimentary evolution of the floodplain approximately up to the 12th century, whereas in the latter evolution period, anthropogenic activity superseded natural factors. This transition occurred more than one millennium later than in other Central and Western European catchments.

    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.

    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 aim of this study was to analyze the prevalence of rickettsiae in the tree-hole tick Ixodes arboricola in the Czech Republic and Slovakia. During May to September of 2009 and 2013, bird boxes belonging to three different areas were screened for ticks. In total, 454 nestlings and 109 nests of 10 hole-breeding bird species were examined. Ticks were found on Ficedula albicollis, Parus major, Cyanistes caeruleus and Sitta europaea and/or in their nests. In total, 166 ticks (17 nymphs, 10 males and 139 females) were found at 3 areas (arithmetic mean±standard error: 55.3±45.9). All ticks were tested for the presence of Rickettsia species by polymerase chain reaction targeting the rickettsial genes gltA, ompA, ompB and htrA and amplicon sequencing. All individuals except 3 nymphs were infected with 'Candidatus Rickettsia vini'. Multilocus sequence typing showed closest proximity to Rickettsia japonica and Rickettsia heilongjiangensis cluster. The presence of 'Ca. R. vini' is reported for the first time in Slovakia. PMID:25769386

    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.

    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. PMID:16292598

    This paper presents and discusses data on oral contraception from a national representative survey (n = 1072) on knowledge, attitudes and practice with regard to contraceptive use in the Czech and Slovak Federal Republic (CSFR). Only 7% of the women at risk of unplanned pregnancy used the pill. The low rate of use seems to be due to the general negative image of oral contraception, reinforced by the experiences of past users and opinions expressed by relative, friends, doctors, and the media. In particular, perceived psychological disadvantages have an important bearing on the decision not to use the method, whereas perceived advantages have hardly any impact. It is likely that this negative image is closely linked with the types of oral contraceptives that have been available in the country and also with the limited choice. Second- and third-generation oral contraceptives have only very recently become available. It is recommended that balanced information on the advantages and disadvantages of oral contraception be made available to doctors and to the general public on a large scale and through a variety of channels.

    The objective of this study is vulnerability and exposer intensity due to land use change in Olomouc, Czech Republic. Vulnerability assessment with exposer intensity to land use/cover change is an important step for enhancing the understanding and decision-making to reduce vulnerability. This study work includes quantification of Exposure Index (EI), Sensitivity Index (SI) and Adaptive Capacity Index (AI). EI is based on intensity of land use/cover change, SI and AI based on natural factors such as elevation, slope, vegetation and land use/cover. Vulnerability Index (VI) derived on the quantification of SI and AI and compared from 1991, 2001 and 2013. Comparing of EI and VI for last three decades, settlements have highest vulnerability index due to high socio-economic activities and water have lowest vulnerability index due to less human interferences. Agriculture has highest exposer index and second highest vulnerability, which show its high rate of exploitation and production. In the study areas, vulnerability tends to increase with the increase of exposure to land use change, but can peak off once the land use start to benefit socio-economically from development. Only in this way we can enhance the adaptive capacity of study area to use change of land.

    This paper presents three indices for evaluation of hydrometeorological extremes, considering them as areal precipitation events and trans-basin floods. In contrast to common precipitation indices, the weather extremity index (WEI) reflects not only the highest precipitation amounts at individual gauges but also the rarity of the amounts, the size of the affected area, and the duration of the event. Furthermore, the aspect of precipitation seasonality was considered when defining the weather abnormality index (WAI), which enables the detection of precipitation extremes throughout the year. The precipitation indices are complemented with the flood extremity index (FEI) employing peak discharge data. A unified design of the three indices, based on return periods of station data, enables one to compare easily inter-annual and seasonal distributions of precipitation extremes and large floods. The indices were employed in evaluation of 50 hydrometeorological extremes of each type (extreme precipitation events, seasonally abnormal precipitation events, and large floods) during the period 1961-2010 in the Czech Republic. A preliminary study of discrepancies among historic values of the indices indicated that variations in the frequency and/or magnitude of floods can generally be due not only to variations in the magnitude of precipitation events but also to variations in their seasonal distribution and other factors, primarily the antecedent saturation.

    The Podlesí granite stock (Czech Republic) is a fractionated, peraluminous, F-, Li- and P-rich, and Sn, W, Nb, Ta-bearing rare-metal granite system. Its magmatic evolution involved processes typical of intrusions related to porphyry type deposits (explosive breccia, comb layers), rare-metal granites (stockscheider), and rare metal pegmatites (extreme F-P-Li enrichment, Nb-Ta-Sn minerals, layering). Geological, textural and mineralogical data suggest that the Podlesí granites evolved from fractionated granitic melt progressively enriched in H 2O, F, P, Li, etc. Quartz, K-feldspar, Fe-Li mica and topaz bear evidence of multistage crystallization that alternated with episodes of resorption. Changes in chemical composition between individual crystal zones and/or populations provide evidence of chemical evolution of the melt. Variations in rock textures mirror changes in the pressure and temperature conditions of crystallization. Equilibrium crystallization was interrupted several times by opening of the system and the consequent adiabatic decrease of pressure and temperature resulted in episodes of nonequilibrium crystallization. The Podlesí granites demonstrate that adiabatic fluctuation of pressure ("swinging eutectic") and boundary-layer crystallization of undercooled melt can explain magmatic layering and unidirectional solidification textures (USTs) in highly fractionated granites.

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

    2010-05-01

    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.

    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.

    This study aimed to examine relationships between DHEA(S), anthropometric parameters, oral glucose tolerance test derived data and lipid spectra in a Czech non-diabetic population. 380 healthy volunteers both with and without a family history of diabetes type 2 (DM2) were enrolled into the study (women: n=235, age 28.9+/-9.4 years, BMI 22.3+/-4.5 kg/m(2), men: n=145, age 32.3+/-10.0 years, BMI 24.7+/-3.6 kg/m(2)). Spearman's correlations (both without and with the adjustment for age, age and BMI), as well as ANCOVA were used. Non-adjusted data showed many "beneficial" correlations between DHEA(S) and both anthropometric and metabolic variables. Statistical analysis revealed that almost all correlations of DHEA(S) to adiposity and fat distribution in men as well as in women disappeared after the adjustment. There are, however, differences between men and women in the correlation of DHEA(S) to insulin sensitivity and lipid levels. The use of hormonal contraceptives (COC) is also an important factor in this relationship. In men and also in women using COC, DHEA-S after adjustment correlated positively with fasting and stimulated glucose, insulin and C-peptide, and negatively with insulin sensitivity. In this respect, the benefit of DHEA(S) supplementation seems -- at least in terms of its alleged antiobesity and antidiabetogenic effects -- to be more than controversial. PMID:18271690

    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. PMID:23137984

    2016-01-01

    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

Total mercury concentrations were determined using a single-purpose atomic absorption spectrophotometer AMA 254. Methylmercury concentrations were determined by gas chromatography. The location where the highest total mercury concentrations in fish muscle tissues were found was the Vltava - Vraňany (0.236±0.1001mg/kg(-1)), and the highest methylmercury concentration was found at the Labe - Obříství (0.231±0.1056mg/kg(-1)). The conclusion based on the data ascertained is that the locations from which the lowest number of fish meat servings can be eaten are the Vltava - Vraňany and the Labe - Obříství. The results of this study helped evaluate contamination levels of rivers that flow out of the Czech Republic. PMID:24360463

    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

    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 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.

    The aim of this study was to describe epidemiological and clinical characteristics of imported enteric fever in Czech travellers and to determine the antimicrobial susceptibility of isolated strains. Retrospective descriptive study included adult patients treated with enteric fever at Hospital Na Bulovce during January 2004-December 2012. A case of typhoid or paratyphoid fever was defined as isolation of Salmonella Typhi or Paratyphi from blood or stool. During the study period, there have been diagnosed 19 cases of enteric fever (12 males and 7 females) with age median of 30 years; 14 cases were caused by Salmonella Typhi and 5 cases by S. Paratyphi A. The infection has been acquired in South Asia (16 patients; 84.2 %), in Africa (Egypt, Angola) in two cases (10.5 %), and in Mexico (1; 5.3 %). Symptoms included fever (all patients), diarrhoea (16 cases; 84.2 %), headache (9; 47.4 %), and abdominal pain (7; 36.8 %). Seventeen patients (89.5 %) were treated with fluoroquinolones; however, the treatment failure was observed in seven of them (41.2 %). Decreased ciprofloxacin susceptibility was detected in eight strains (66.7 %), and one strain (8.3 %) was multidrug resistant. Sequence analysis of quinolone resistance-determining regions (QRDR) of the gyrA gene revealed the presence of amino acid substitutions in all tested isolates with decreased ciprofloxacin susceptibility. Typhoid and paratyphoid fevers represent epidemiologically important diseases that may lead to potentially life-threatening complications. Major issue in the management of enteric fever represents the non-susceptibility of Salmonella strains to fluoroquinolones and other antimicrobials. PMID:25394534

    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

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

    NASA Astrophysics Data System (ADS)

    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

    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. PMID:18394682

    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.

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

    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

    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

    The aim of this study was to compare the contamination levels of certain important fishing grounds in the Czech Republic and to assess the health risk of consuming the fish from these localities. The assessment was performed from 2006 to 2010 in 27 fishing grounds. Within this project, 707 fish from 14 different species were sampled. The concentration of selected toxic metals (Hg, Pb, Cd) and persistent organic pollutants (POPs), such as non-dioxin-like polychlorinated biphenyls (NDL-PCBs), hexachlorocyclohexane (HCH) isomers, dichlorodiphenyltrichloroethane (DDT) and its metabolites (o,p´-DDE; p,p´-DDE; o,p´-DDD; p,p´-DDD; o,p´-DDT; p,p´-DDT) and hexachlorobenzene (HCB), were analysed in the muscle tissue of the sampled fish. Atomic absorption spectrometry (AAS) was used for the analysis of toxic metals. All of the POPs were analysed using gas chromatography with an electron capture detector (GC/ECD). Common bream (Abramis brama) was chosen as a reference fish species for the comparison of fishing grounds. Mercury was found as a major pollutant in fish flesh at all of the sampling sites. Concentrations in excess of the maximum level (ML) of mercury in the muscle tissue of fish (0.5 mg kg(-1)) were registered in 32 samples. Concentrations of other monitored toxic metals in fish muscle were low, typically below the limit of quantification (LOQ). From the tested POPs, DDTs and NDL-PCBs were found as major pollutants. ML for NDL-PCBs (ICES-6) in muscle tissue of fish (0.125 mg kg(-1)) was exceeded in 7 samples. In case of tested pesticides, concentrations in excess of the MRL were not registered. PMID:25173745

    Rectal smears of calves, cows and young bulls, as well as cloacal smears of house sparrows (Passer domesticus), from farms at the villages of Sumice and Troskotovice, Czech Republic, were examined for E. coli resistant to 12 antimicrobials. The resistant isolates were tested for antimicrobial-resistance genes and integrons. Totals of 40% (n=183), 3% (n=95), 0% (n=33), and 9% (n=54) of Escherichia coli isolates from calves, cows, young bulls and house sparrows, respectively, were antimicrobial resistant. The following genes were identified in cattle E. coli isolates: tetA, tetB (isolates resistant to tetracycline), bla(TEM) (beta-lactams), strA, aadA (streptomycin), sul1, sul2 (sulphonamides), and cat, floR (chloramphenicol). Seven of 16 antimicrobial-resistant calf isolates from the Sumice farm possessed class 1 integrons with the aadA1 gene cassette integrated, 1 kb in size. On the Troskotovice farm, eight of 57 antimicrobial-resistant calf isolates possessed class 1 integrons. Integrons of 1.5kb with the dhfr1- aadA1 gene cassette were found in four isolates, followed by a 1kb integron with the aadA1 gene found in three isolates, and a 1.7kb integron with the dhfr17-aadA5 gene cassette and the phenotype ASSuTSxtNaCipCCfG. The prevalence of resistant E. coli in calves compared to adult cattle was much higher and probably was influenced by oral antimicrobial usage in calves, feeding with milk and colostrum from treated cows, as well as mechanisms unrelated to antimicrobial drug selection. Although house sparrows lived together with the cattle and came into contact with cattle waste on the farm, they were not infected by resistant E. coli isolates with the same characteristics as those found in cattle.

    The subsurface of the Earth has a certain capability to remember what has happened on its surface tens to hundreds of years ago. Ground surface temperature (GST) history, reflecting past climate conditions, can be evaluated by analysing the excursions left on the present-day temperature-depth distribution measured by precise temperature loggings in the boreholes. Temperature logs from fifteen selected holes were inverted into GST histories to assess the corresponding climatic changes. These temperature records generally represent typical conditions existing on the territory of the Czech Republic. In combination with the GST reconstructions from our previous works, these data were used to assess the regional pattern of the last 250-year climatic change. The GSTs were obtained by applying the generalized least-squares inversion method [Jackson, D.D., 1972. Interpretation of inaccurate, insufficient and inconsistent data. Geophys. J. R. Astron. Soc. 28, 97-109], whereby the additional information on interdependence of both measured data and climate changes can be incorporated into the model in the form of covariance matrices. Three main episodes can be distinguished in the last 250 years: a warm period between 1790 and 1830, a slightly colder period in 1940-1960, and a general warming with the average rates of 0.01-0.03 K/year since then. The geographical distribution of the recent warming rate may indicate an impact of human activities. The verification of the GST assessment was accomplished by the independent past climate reconstructions gained by the use of historical sources and instrumental records.

    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.

    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.). PMID:25916466

    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.

    Results of a recent molecular epidemiological study of 1,3-butadiene (BD) exposed Czech workers, conducted to compare female to male responses, have confirmed and extended the findings of a previously reported males only study (HEI Research Report 116, 2003). The initial study found that urine concentrations of the metabolites 1,2-dihydroxy-4-(acetyl) butane (M1) and 1-dihydroxy-2-(N-acetylcysteinyl)-3-butene (M2) and blood concentrations of the hemoglobin adducts N-[2-hydroxy-3-butenyl] valine (HB-Val) and N-[2,3,4-trihydroxy-butyl] valine (THB-Val) constitute excellent biomarkers of exposure, both being highly correlated with BD exposure levels, and that GST genotypes modulate at least one metabolic pathway, but that irreversible genotoxic effects such as chromosome aberrations and HPRT gene mutations are neither associated with BD exposure levels nor with worker genotypes (GST [glutathione-S-transferase]-M1, GSTT1, CYP2E1 (5' promoter), CYP2E1 (intron 6), EH [epoxide hydrolase] 113, EH139, ADH [alcohol dehydrogenase]2 and ADH3). The no observed adverse effect level (NOAEL) for chromosome aberrations and HPRT mutations was 1.794 mg/m(3) (0.812 ppm)--the mean exposure level for the highest exposed worker group in this initial study. The second Czech study, reported here, initiated in 2003, included 26 female control workers, 23 female BD exposed workers, 25 male control workers and 30 male BD exposed workers (some repeats from the first study). Multiple external exposure measurements (10 full 8-h shift measures by personal monitoring per worker) over a 4-month period before biological sample collections showed that BD workplace levels were lower than in the first study. Mean 8-h TWA exposure levels were 0.008 mg/m(3) (0.0035 ppm) and 0.397 mg/m(3) (0.180 ppm) for female controls and exposed, respectively, but with individual single 8-h TWA values up to 9.793 mg/m(3) (4.45 ppm) in the exposed group. Mean male 8-h TWA exposure levels were 0.007 mg/m(3) (0.0032 ppm
