    The publication has a cognitive research character. It presents a comparative analysis of free Internet services in Poland and abroad, used to adjust the data obtained using satellite measurement techniques. The main aim of this work is to describe and compare free tools for satellite data processing and to examine them for possible use in the surveying works in Poland. Among the many European and global services three of them dedicated to satellite measurements were selected: ASG-EUPOS (Poland), APPS (USA) and CSRS (Canada). The publication contains the results of calculations using these systems. Calculations were based on RINEX files obtained via postprocessing service (ASG-EUPOS network) POZGEO D for 12 reference stations in the South Poland. In order to examine differences in results between the ASG-EUPOS, APPS and CSRS the transformation points coordinate to a single coordinate system ETRF 2000 (in force in Poland) was made. Studies have shown the possibility of the calculation in Poland (in postprocessing mode) using the analyzed applications with global coverage.

    This study compares the social determinants of individual health between the United States, a capitalist society, and Poland, a 'post-communist' society. The effects of demographic factors, family characteristics and socioeconomic status on self-reported health are estimated with OLS regression using data from the 1994 American and Polish General Social Surveys. The results show lower self-reported health and more rapid declines in health for people over 60 in Poland than in the United States. Also, in Poland, women report worse health than do men while the opposite is found for the United States. The relationships between education, income and health were stronger in the United States than in Poland. Age, gender and SES may operate differently in the two countries because of a gap in social development (e.g. varying living standards and styles, health care systems and cultural attitudes) between the West and the former Eastern Europe.

    This study presents the results of the analysis of the remains of 23 executed male individuals aged between 21 and 63 years, recovered from Osobowicki Cemetery in Wroclaw (Poland), field 83B, in 2012. In 1948 and 1949, prisoners sentenced to death by firing squad--most of them associated with the post-war anti-communist underground independence movement in Poland--were buried there. The aim of the study was to analyse fatal wounds and the method of execution, and to compare the results to data from archival documents. The results were also compared with studies concerning executions during a later period, i.e. 1949-1954. The research on the method of execution during this period of history carried out during the exhumations in Osobowicki Cemetery was the first conducted on such a scale in Poland. Forensic analysis revealed a wide variety of gunshot wounds inflicted during executions, revealing both gunshots to the head, especially single shots to the back of the head, and cases corresponding to the use of a firing squad, probably equipped with machine guns. The results of the research indicate that capital punishment by shooting was carried out in ways both similar to those the specified in the regulations and completely different. PMID:24767546

    The aim of the project is to develop national database of seismic activity for seismic hazard assessment. Poland is known as a region of very low seismicity, however some earthquakes occur from time to time. The historical catalogue consists of less than one hundred earthquakes in the time span of almost one thousand years. Due to such a low occurrence rate, the study has been focussing on events at magnitudes lower than 2 which are more likely to occur during a few-year-long project. There are 24 mobile seismic stations involved in the project which are deployed in temporary locations close to humans neighbourhood. It causes a high level of noise and disturbances in recorded seismic signal. Moreover, the majority of Polish territory is covered by a thick sediments. It causes the problem of a reliable detection method for small seismic events in noisy data. The majority of algorithms is based on the concept of STA/LTA ratio and is designed for strong teleseismic events registered on many stations. Unfortunately they fail on the problem of weak events in the signal with noise and disturbances. It has been decided to apply Real Time Recurrent Neural Network (RTRN) to detect small natural seismic events from Poland. This method is able to assess relations of seismic signal in frequency domains as well as in time of seismic phases. The RTRN was taught by wide range of seismic signals - regional, teleseismic as well as blasts. The method is routinely used to analyse data from the project. In the firs two years of the project the seismic network was set in southern Poland, where relatively large seismicity in known. Since the mid-2010 the stations have been working in several regions of central and northern Poland where some minor historical earthquakes occurred. Over one hundred seismic events in magnitude range from 0.5 to 2.3 confirms the activity of Podhale region (Tatra Mountains, Carpathians), where an earthquake of magnitude 4.3 occurred in 2004.

    This study compared the characteristics of probability samples of homeless adults in Poland (N = 200 from two cities) and the United States (N = 219 from one city), using measures with established reliability and validity in homeless populations. The same measures were used across nations and a systemic translation procedure assured comparability of measurement. The two samples were similar on some measures: In both nations, most homeless adults were male, many reported having dependent children and experiencing out-of-home placements when they themselves were children, and high levels of physical health problems were observed. Significant national differences were also found: Those in Poland were older, had been homeless for longer, showed lower rates on all psychiatric diagnoses assessed (including severe mental and substance abuse disorders), reported less contact with family and supportive network members, were less satisfied when they sought support from their networks, and reported fewer recent stressful life events and fewer risky sexual behaviors. Culturally-informed interpretations of these findings and their implications are presented. PMID:24473922

  8. Could socio-economic transformation and the resulting psychological stress influence cancer risk in Opole province, Poland?

    2005-09-01

    The paper presents the results of a risk assessment analysis of cancer morbidity in Opole province before and after a political transformation in Poland, i.e. in the 1985-1989 quinquennium and the following two equivalent periods of: 1990-1994 and 1995-1999. Measures of morbidity are given and its growth in males and females are compared with the ageing effect as well as with unemployment. In the paper a general conclusion has been drawn suggesting that the socio-economic transformation begun after 1989 and the resulting stress could have been the one of the possible background effects influencing the health status in the region. It must be accentuated, however, that the relation has not been a subject of statistical proving due to a methodological impossibility; a divagated question is offered for scientific concern and open discussion.

    Although hydrogen is one of the fundamental constituents of the earth's atmosphere its global balance is still poorly clarified. A few developed inventories diverging values for efficiency of sources and sinks of this gas. The European network for the hydrogen concentrations measurement is based on several unevenly spaced measurement points. While in 2009 MPI Jena has delivered accurate scale for hydrogen measurements and the techniques of analyses are well described, still large areas of Central Europe is uncovered by representative stations. The first measurement point, established under the EUROHYDROS EU program, on the territory of Poland was Kraków city. Different laboratory setups was tested there and compared to each other. The Kraków area has significant car traffic and its geographical location implies frequent temperature inversions in lower troposphere leading to the accumulation of trace gases in atmosphere of the city. Observations launched in 2007 revealed that the concentration of hydrogen fluctuates strongly within diurnal and seasonal timescales. Its average concentration is three times larger than this, observed at the other stations. The European "background" concentrations of hydrogen are not reflected in the Krakow record. An ideal place to carry out observation of the regional air composition for Central Europe is a research station located in the meteorological observatory at Kasprowy Wierch. Measurement point at the top of mountain peak with elevation of 2000m a.s.l. gives an access to the well mixed troposphere. The station delivers also the necessary facilities and logistics. Since year 1996 greenhouse gas measurement program has been operating at this point. The first measurements of atmospheric concentrations of hydrogen at Kasprowy Wierch were performed in year 2010, based on dedicated gas chromatograph using RGD detector installed at the station. Analysis of hydrogen content in the outside air is performed without any enrichment

    History of hematopoietic stem cell transplantations in Poland begins in early 1980s; the 1st bone marrow allotransplantation was performed in 1983 in the Central Clinical Hospital of the Military Medical Academy in Warsaw. Following years brought the 1st autologous stem cell transplantations. Ten years later, unrelated bone marrow transplantation was performed for the 1st time by the team of the Hematology and Blood and Marrow Transplantation Unit in Katowice. Since then, hematopoietic stem cell transplantation developed to be standard procedure and one of the most important therapies applied in leukemia treatment. The number of allotransplantations in Poland has grown significantly in the past 2 decades, which generated new needs and problems. In 2005, based on a new Transplant Law, a National Transplants Registry was created. Its main role is to collect data (registration of procedures and follow-up data) related to every transplantation case for stem cells and tissues as well as for organs. We present statistics concerning stem cell transplantations performed in Poland, as collected in the National Transplants Registry in the years 2006-2014. There are 18 centers transplanting hematopoietic stem cells in Poland. The total number of hematopoietic stem cell transplantations performed in 2006-2014 was 3,537, with allotransplantations from relatives accounted for 1,491 and from unrelated donors for 2,046. The main indication for allotransplantation in past years was acute leukemia. PMID:27496493

  11. Comparative Soot Diagnostics: Preliminary Results

    The motivation for the Comparative Soot Diagnostics (CSD) experiment lies in the broad practical importance of understanding combustion generated particulate. Depending upon the circumstances, particulate matter can affect the durability and performance of combustion equipment, can be a pollutant, can be used to detect fires and, in the form of soot, can be the dominant source of radiant energy from flames. The nonbuoyant structure of most flames of practical interest makes understanding of soot processes in low gravity flames important to our ability to predict fire behavior on earth. These studies also have direct applications to fire safety in human-crew spacecraft, since smoke is the indicator used for automated detection in current spacecraft. In the earliest missions (Mercury, Gemini and Apollo), the crew quarters were so cramped that it was considered reasonable that the astronauts would rapidly detect any fire. The Skylab module, however, included approximately 20 UV-sensing fire detectors. The Space Shuttle has 9 particle-ionization smoke detectors in the mid-deck and flight deck and Spacelab has six additional particle-ionization smoke detectors. The designated detectors for the ISS are laser-diode, forward-scattering, smoke or particulate detectors. Current plans for the ISS call for two detectors in the open area of the module, and detectors in racks that have both cooling air flow and electrical power. Due to the complete absence of data concerning the nature of particulate and radiant emission from incipient and fully developed low-g fires, all three of these detector systems were designed based upon l-g test data and experience. As planned mission durations and complexity increase and the volume of spacecraft increases, the need for and importance of effective, crew-independent, fire detection grows significantly. To provide this level of protection, more knowledge is needed concerning low-gravity fire phenomena and, in particular, how they might be

    The author reviews recent evidence concerning the emigration potential of Russia and Eastern Europe, using data from a 1991 survey of 4,269 respondents. "It is demonstrated that the proportion of adults wishing to emigrate from each of these countries in February 1991 varied from a low of 2 per cent in Lithuania to a high of 13 per cent in Poland. Total emigration potential from the region is estimated to have been between 10.2 and 16.7 million....A multiple regression analysis indicates that age and pessimism concerning democracy are the main factors that were independently associated with desire to emigrate."

    Anually laminated (varved) lake deposits are suitable natural archives for reconstructing past climatic and environmental changes at seasonal resolution. A major advantage of such records is that varve counting allows constructing robust and independent chronologies, a key challenge for paleoclimate research. Recently, a new annually laminated sediment record has been obtained from Lake Jelonek, located in the eastern part of the Pomeranian Lakeland in northern Poland (Tuchola Pinewoods). The lake is surrounded by forest and covers an area of 19,9 ha and has a maximum depth of 13,8 m. Three overlapping series of 14,3 m - long sediment records have been cored with an UWITEC 90 mm diameter piston corer from the deepest part of the lake. A continuous master composite profile has been established comprising the entire postglacial lacustrine sediment infill. Preliminary analyses including micro-facies analyses on thin sections from selected intervals as well as X-ray fluorescence element scanning (µ-XRF) reveal that the sediments are to a large part annually laminated. Here we present detailed varve models for different sediment intervals and discuss high-resolution geochemical variation in the entire sediment record. A preliminary age model based on radiocarbon dating and major biostratigraphical boundaries based on pollen data will be presented as well. These data will form the fundament for the planned multi-proxy study for detailed reconstructions of climatic and environmental variability during the late glacial and Holocene in the southern Baltic.

    Background Electronic cigarettes vaporize nicotine dissolved in glycerine and/or propylene glycol (e–liquid). Due to a lack of regulations, e-liquids may contain inaccurately labelled nicotine levels. Our aim was to test nicotine levels in samples of e-liquids from three countries. Methods We measured nicotine concentration in 32, 29 and 30 e-liquids purchased between 2013 and 2014 from locations in the United States (US), South Korea, and Poland, respectively. Results Nicotine concentration in the US products varied from 0 to 36.6 mg/mL. Traces of nicotine were found in three US products labelled as ‘nicotine free’. Two-thirds of South Korean products did not contain detectable amounts of nicotine, whereas nicotine concentration in other products varied from 6.4±0.7 to 150.3±7.9 (labelled as ‘pure nicotine’) mg/mL. In products from Poland, nicotine concentration varied from 0 to 24.7±0.1 mg/mL. Overall, we found significant discrepancies (>20%) in the labelled nicotine concentrations in 19% of analysed e-liquids. Conclusion Most of the analysed samples had no significant discrepancies in labelled nicotine concentrations and contained low nicotine levels. However some products labelled as ‘nicotine-free’ had detectable levels of the substance, suggesting insufficient manufacturing quality control. We identified a single product labelled as ‘pure nicotine’ which contained significantly higher concentration of the drug, increasing the risk of accidental poisoning. The study reveals the need for quality standards of these new nicotine containing products. PMID:25724267

    Background We performed a clinical audit of preoperative rectal cancer treatment at two European radiotherapy centres (Poland and Spain). The aim was to independently verify adherence to a selection of indicators of treatment quality and to identify any notable inter-institutional differences. Methods A total of 162 patients, in Catalan Institute of Oncology (ICO) 68 and in Greater Poland Cancer Centre (GPCC) 94, diagnosed with locally advanced rectal cancer and treated with preoperative radiotherapy or radio-chemotherapy were included in retrospective study. A total of 7 quality control measures were evaluated: waiting time, multidisciplinary treatment approach, portal verification, in vivo dosimetry, informed consent, guidelines for diagnostics and therapy, and patient monitoring during treatment. Results Several differences were observed. Waiting time from pathomorphological diagnosis to initial consultation was 31 (ICO) vs. 8 (GPCC) days. Waiting time from the first visit to the beginning of the treatment was twice as long at the ICO. At the ICO, 82% of patient experienced treatment interruptions. The protocol for portal verification was the same at both institutions. In vivo dosimetry is not used for this treatment localization at the ICO. The ICO utilizes locally-developed guidelines for diagnostics and therapy, while the GPCC is currently developing its own guidelines. Conclusions An independent external clinical audit is an excellent approach to identifying and resolving deficiencies in quality control procedures. We identified several procedures amenable to improvement. Both institutions have since implemented changes to improve quality standards. We believe that all radiotherapy centres should perform a comprehensive clinical audit to identify and rectify deficiencies. PMID:24991212

    The use of veterinary medicinal products in food producing animals for a variety of purposes causes that their residues may be presented in edible tissues. As a result, in concern of public health, European Union Countries establish each year monitoring plans and they control the levels of harmful substances in food of animal origin. This paper presents survey of residues of veterinary medicinal products and coccidiostats in eggs for Poland and European Union in years 2007-2010. Despite the decrease in reported non-compliant results for coccidiostats, the numbers were still higher than those for veterinary medicines. The most often determined coccidiostats were: nicarbazin, dinitrocarbanilide, salinomycin and lasalocid, and the most often reported non-compliant results for veterinary medicines were: antimicrobials, enrofloxacin and doxycycline.

    Over the past two decades Clostridium difficile infection (CDI) has appeared as a major public health threat. We performed a retrospective study based on the records of patients hospitalized for CDI at the University Hospital in Krakow, Poland, between 2008 and 2014. In the study period, CDI occurred in 1009 individuals. There were 790 (78%) individuals who developed infection only once, whereas 219 (22%) developed infection more than once. The percentage of deaths within 14 days of CDI confirmation was 2·4%, with a mean age of 74·2 ± 15·9 years. Crude mortality was 12·9% in medical wards, 5·6% for surgical wards and 27·7% in the ICU setting. The time span between diagnosis and death was 5·1 days on average. Between 2008 and 2012 a 6·5-fold increase of CDI frequency with a posterior stabilization and even reduction in 2013 and 2014 was observed. According to the data analysed, 2/3 patients in our population developed CDI during their hospitalization even though they were admitted for different reasons. Medical wards pose a significantly higher risk of CDI than the surgical ones. Age is a risk factor for CDI recurrence. In the case of patients who died, death occurred shortly after diagnosis. The first CDI episode poses much higher risk of mortality than the consecutive ones. PMID:25858553

    Purpose To comprehensively identify the determinants of quality of life (QoL) in a population study sample of persons aged 18–50 and 50+. Methods In this observational, cross-sectional study, QoL was measured with the WHOQOL-AGE, a brief instrument designed to measure QoL in older adults. Eight hierarchical regression models were performed to identify determinants of QoL. Variables were entered in the following order: Sociodemographic; Health Habits; Chronic Conditions; Health State description; Vision and Hearing; Social Networks; Built Environment. In the final model, significant variables were retained. The final model was re-run using data from the three countries separately. Results Complete data were available for 5639 participants, mean age 46.3 (SD 18.4). The final model accounted for 45% of QoL variation and the most relevant contribution was given by sociodemographic data (particularly age, education level and living in Finland: 17.9% explained QoL variation), chronic conditions (particularly depression: 4.6%) and a wide and rich social network (4.6%). Other determinants were presence of disabling pain, learning difficulties and visual problems, and living in usable house that is perceived as non-risky. Some variables were specifically associated to QoL in single countries: age in Poland, alcohol consumption in Spain, angina in Finland, depression in Spain, and self-reported sadness both in Finland and Poland, but not in Spain. Other were commonly associated to QoL: smoking status, bodily aches, being emotionally affected by health problems, good social network and home characteristics. Conclusions Our results highlight the importance of modifiable determinants of QoL, and provide public health indications that could support concrete actions at country level. In particular, smoking cessation, increasing the level of physical activity, improving social network ties and applying universal design approach to houses and environmental infrastructures could

  20. Successive episodes of normal faulting and fracturing resulting from progressive extension during the uplift of the Holy Cross Mountains, Poland

    NASA Astrophysics Data System (ADS)

    Konon, Andrzej

    2004-03-01

    Conjugate normal faults, extension fractures and mesh-fracture structures were investigated in Devonian carbonate rocks from the southern part of the Holy Cross Mountains (HCM) (Central Poland). Strata folded during Variscan deformations were later subject to uplift, resulting in increasing extension in the upper part of the rock mass. At a relatively shallow depth, faults and fractures developed in an orderly vertical succession. First, mesh fracture structures and conjugate normal fault sets enclosing acute dihedral angles (2Θ) of over 45° were formed. Next, conjugate normal faults with 2Θ less than 45° and sub-vertical extension fractures developed. The occurrences of conjugate normal sets enclosing different dihedral acute angles and extension fractures with similar strikes, juxtaposed with each other at the same stratigraphic level, point to the fact that the uplifted rock mass underwent successive changes in a stress regime leading to the formation of these structures. The first sets of conjugate normal faults and fractures developed when the HCM were uplifted during a late stage of Variscan deformations. The next sets of extension fractures and conjugate normal faults developed during the following uplift events interrupted by periods of sedimentation of the Mesozoic and younger strata.

    Southern Podlasie is a specific region as regards HIV/AIDS hazards for its geographical position (border zone) as well as social problems (high level of unemployment). The aim of the research was to find out the level of knowledge of rural youth on the subject of risk factors and ways of spreading HIV as well as AIDS clinic. 405 students aged 15-17 (197 males and 208 females) that attend chosen rural schools on the territory of Southern Podlasie were questioned. The method of diagnostic poll was employed in the research using the questionnaire "HIV/AIDS knowledge and beliefs" from international studies on school youth health preservation (HBSC)--the supervisor of the project in Poland is professor B. Woynarowska). The research has shown different levels of knowledge of rural youth on the subject of HIV/AIDS. There were still many false opinions among the people questioned about the ways of HIV infection. Despite considerable knowledge about the ways of reducing the risk of HIV infection, there was low level of knowledge concerning AIDS treatment compared with the results of nationwide survey, there were fewer correct answers in our study group. It is the duty of schools, parents and mass media to provide the youth with relevant information on the subject of HIV/AIDS. Only systematic education in this domain can protect the infected persons and their partners or children against the consequences of ignoring the disease. PMID:15002230

    The five-year goal of this effort is to calculate high fidelity mid-UV spectra for individual stars and stellar systems for a wide range of ages, abundances, and abundance ratios. In this first year, the emphasis was placed on revising the list of atomic line parameters used to calculate mid-UV spectra. First, new identifications of atomic lines and measurements of their transition probabilities were obtained for lines of the first and second ionization stages of iron-peak elements. Second, observed mid-UV and optical spectra for standard stars were re-analyzed and compared to new calculations, to refine the determination of transition probabilities and to estimate the identity of lines still missing from the laboratory lists. As evidenced by the figures, a dramatic improvement has resulted in the reproduction of the spectra of standard stars by the calculations.

    Due to the supra-regional importance of areas of intensive agriculture, it is important to identify factors, that are affecting the size of the drainage basin. One of the methods that will allow to determine relations is the spatial valorization of environmental elements, that affect the circulation of water. Such analysis was performed for highly agricultural region in the central part of Poland (52° 30'N, 18° 50'E). The study area was Zglowiaczka basin, which covers an area of 1.495,6 km2.With the help of GIS methods and tools, there have been designated from thematic maps these factors of natural environment elements, that influence the size of the outflow. Basing on topographic maps at 1:25000 scale, river network, river length has been calculated, hydrographic objects such as lakes, swamps, marshes have been inventoried and the land use has been partly assessed. For the evaluation of the terrain there has been used a DTM in the form of a raster, that was created on the base of analyzing photogrametric materials. Its accuracy is similar to topographic maps at 1:10000 scale, with 1m vertical resolution. It was mainly used to determine the slopes, and watersheds deletion. It was also required to determine the length of some contours of the catchment's - the material needed for the expected value of runoff in the model. To determine the land use - mainly for agricultural use of crop type, Corine Land Cover 2000 was used. To determine the lithology and as a result - the infiltration, there were used both geological and soil maps.

    Background Cigarette smoking remains the leading preventable cause of death and disease. Thus, all activities aiming to reduce smoking play an important role in improving population health. The positive role of the general practitioner (GP) in smoking cessation could increase the success rate for quitting smoking, if compared with unassisted cessation. The aim of this study was to determine what kind of general practitioner smokers need in order to stop smoking. Methods Four focus groups with 12 current and 12 former smokers (aged 20-59, 11 women and 13 men), were arranged in the city of Toruń, Poland, with a view to describe their opinions on the GP’s role in smoking cessation. The data were subjected to descriptive qualitative content analysis. Results Two major themes emerged in the analysis: the smokers’ positive and negative experiences of the GP in smoking cessation and their expectations regarding the role of the GP in smoking cessation. The first theme embraced the following subthemes: (1) GP’s passivity, (2) routine questions about the patient’s smoking during the visit, (3) lack of time during the visit, and (4) the role model of the GP in smoking cessation. Within the second theme, the respondents identified the following subthemes: (1) bringing up the topic of smoking cessation, even in situations when the patient is unprepared for this; (2) the necessity of a tailored approach to the patient; (3) access to information and evidence confirming the harms of smoking tobacco; (4) prescription of pharmacological and other treatment; and (5) referral to specialists in smoking cessation. Conclusions Patients expect their GP to actively participate in smoking cessation through a more tailored approach to the patient’s needs. The patients’ experiences did not match their expectations: the smokers rarely got advice on smoking cessation from their GPs. Finally, they emphasized the importance of the GP as a role model in smoking cessation. PMID

    Dietary intake of macro-, trace and toxic elements was determined among the young adult population of Eastern Poland. The study was performed in 2011-2013 and involved 583 participants living in Lublin and its province. Dietary intakes of metals were determined using a 24h dietary recall technique and a market basket method. The analytical quantification of As, Ca, Cd, Cu, Fe, K, Mg, Mn, Mo, Na, Ni, Pb, Se and Zn was performed using ICP-MS technique, whereas the content of mercury was determined using the Mercury Analyzer. Performed investigations revealed that daily dietary intakes of the majority of the study elements (macro- and trace) and toxic elements such as As, Pb or Hg are within the range of reference values. However, high consumption of Na and improper Na/K ratio combined with low intake of Mg may be harmful to the health of the population. Moreover, obtained data suggest that the risk of developing diseases among population in Eastern Poland related to high exposure to Ni and Cd absorbed from foodstuffs was high. PMID:27049125

    Individual dosimetry service based on thermoluminescence (TLD) detectors has started its activity at the Institute of Nuclear Physics (IFJ) in Krakow in 1965. In 2002, the new Laboratory of Individual and Environment Dosimetry (Polish acronym LADIS) was established and underwent the accreditation according to the EN-PN-ISO/IEC 17025 standard. Nowadays, the service is based on the worldwide known standard thermoluminescent detectors MTS-N (LiF:Mg,Ti) and MCP-N (LiF:Mg,Cu,P), developed at IFJ, processed in automatic thermoluminescent DOSACUS or RE2000 (Rados Oy, Finland) readers. Laboratory provides individual monitoring in terms of personal dose equivalent H(p)(10) and H(p)(0.07) in photon and neutron fields, over the range from 0.1 mSv to 1 Sv, and environmental dosimetry in terms of air kerma K(a) over the range from 30 μGy to 1 Gy and also ambient dose equivalent H*(10) over the range from 30 μSv to 1 Sv. Dosimetric service is currently performed for ca. 3200 institutions from Poland and abroad, monitored on quarterly and monthly basis. The goal of this paper is to identify the main activities leading to the highest radiation exposures in Poland. The paper presents the results of statistical evaluation of ∼ 100,000 quarterly H(p)(10) and K(a) measurements performed between 2002 and 2009. Sixty-five per cent up to 90 % of all individual doses in Poland are on the level of natural radiation background. The dose levels between 0.1 and 5 mSv per quarter are the most frequent in nuclear medicine, veterinary and industrial radiography sectors. PMID:21183549

    Poland, a post-socialist democracy with a high interest in successful integration with the European Union and a strong catholic tradition, currently has some of the most restrictive anti-drug laws in Europe. Structural violence towards drug users has intensified as a result of decades of shifting drug policies and, surprisingly, the more recent process of political and economic liberalization. This commentary considers the contextual and historical dynamics of drug policy-making in Poland. It traces transitions in Poland's drug control policy, throughout Poland's history as a soviet satellite state, under martial law, and in the democracy that it is today. This case study draws on an analysis of interviews with key actors and participant observations in combination with documents and archival records. This paper follows the changes in Poland's drug control policy, throughout Poland's history as a soviet satellite state, under martial law, and in the democracy that it is today. Factors contributing to the enactment of restrictive drug laws have occurred in a highly politicized context during a series of dramatic political transitions. Current drug policies are woefully inadequate for treating those in need of drug treatment and care as well as for preventing HIV and other harms linked to drug injecting. PMID:27140431

    Kocinka catchment with 258 km2 of surface area is one of the Soils2Sea project (BONUS programme) case studies. One of the main scientific objectives of this project is to analyze how changes in land use and climate may affect the nutrient load to the Baltic Sea. Hydrogeological conditions in the Kocinka catchment are determined by Quaternary glacial till and glacifluvial sands and gravels underlain by karstic-fractured limestones which compose the Upper Jurassic Major Groundwater Basin (MGWB 326), one of four most important groundwater reservoirs in Poland. Pollution with nitrates is the most important threat to groundwater quality in this groundwater body. The concentration of nitrate in some wells, in the southern part of Kocinka catchment where outcrops of Jurassic limestones occur, exceeds the maximum permissible level of 50 mgNO3/L and constantly increases. A prerequisite for measures to reduce NO3 loads to the groundwater body is identification of sources of nitrate pollution. The working hypothesis links the high nitrate concentrations with the leaking sewage system in Czestochowa city and its surroundings but agricultural sources cannot be excluded as 66% of Kocinka catchment area is used agriculturally. A dedicated study employing environmental tracers was launched with the main aim of quantifying the pathways and dynamic of groundwater flow in the aquifer. Tritium was found throughout the system but its concentrations vary considerably. Decrease of tritium contents with depth in the aquifer was observed in one of wells. This points to active recharge and characteristic time scales of groundwater flow in order of years to several decades. To identify the origin of nitrate pollution nitrogen and oxygen isotope ratios of dissolved nitrate was analyzed in a number of wells with high nitrate concentrations. The isotopic composition of dissolved nitrates does not confirm the hypothesis on the decisive role of urban sewage in nitrate pollution. The isotope date

    To investigate temporal variability of methane (CH4) fluxes in an urban environment, air-surface exchange fluxes of CH4 were continuously measured using eddy covariance techniques at a city-centre site in Łódź, Poland, from July 2013 to August 2015. In the immediate vicinity of the measurement site, potential methane sources include vehicle traffic, dense sewerage infrastructure and natural gas networks. Sensible and latent heat fluxes have also been measured since 2000 and carbon dioxide fluxes since 2007 at this site. Upward CH4 fluxes dominated during the measurement period, indicating that the city centre is a net source of CH4 to the troposphere. The highest monthly fluxes were observed in winter (2.0 to 2.7 g m-2 month-1) and the lowest in summer (0.8 to 1.0 g m-2 month-1). Fluxes on working days were around 6 % higher than on weekends. The cumulative flux indicates that the city centre emitted a net quantity of nearly 18 g m-2 of CH4 in 2014. Stable values of the FCO2/ FCH4 ratio in months (minimum 2.41 × 10-3, maximum 5.3 × 10-3) and the lack of a clear annual course suggest comparable magnitude of both fluxes.

  13. Air protection strategy in Poland

    Blaszczyk, B.

    1995-12-31

    Air quality is one of the basic factors determining the environmental quality and influencing the life conditions of people. There is a shortage of proper quality air in many regions of Poland. In consequence, and due to unhindered transport, air pollution is the direct cause of losses in the national economy (reduction of crops, losses in forestry, corrosion of buildings and constructions, worsening of people`s health). Poland is believed to be one of the most contaminated European countries. The reason for this, primarily, is the pollution concomitant with energy-generating fuel combustion; in our case it means the use of solid fuels: hard coal and lignite. This monocultural economy of energy generation is accompanied by low efficiency of energy use (high rates of energy loss from buildings, heat transmission pipelines, energy-consuming industrial processes). This inefficiency results in the unnecessary production of energy and pollution. Among other reasons, this results from the fact that in the past Poland did not sign any international agreements concerning the reduction of the emission of pollution. The activities aimes at air protection in Poland are conducted based on the Environmental Formation and Protection Act in effect since 1980 (with many further amendments) and the The Ecological Policy of the state (1991). The goals of the Polish air pollution reduction program for the period 1994-2000 are presented.

    With 38 million residents, Poland has the eighth-largest population in Europe. A successful transition from communism to democracy, which began in 1989, has brought several significant changes to the country's economic development, demographic structure, quality of life, and public policies. As in the other European countries, Poland has been facing a rapid increase in the number of older adults. Currently, the population 65 and above is growing more rapidly than the total population and this discrepancy will have important consequences for the country's economy. As the population ages, there will be increased demands to improve Poland's health care and retirement systems. This article aims to provide a brief overview of the demographic trends in Poland as well a look at the country's major institutions of gerontology research. The article also describes key public policies concerning aging and how these may affect the well-being of Poland's older adults. PMID:26315315

    We report the results of a survey of the attitudes and practices of paediatricians in Warsaw, Poland, with respect to the treatment of infants born with severe handicaps. The results are compared with a similar survey conducted by Australian researchers (1). In the Polish medical community surveyed, unconditional respect for life is a dominant attitude. Our study has revealed a deeply-entrenched paternalistic attitude among Polish doctors and a strong unwillingness to distinguish between 'ordinary and extraordinary means' of prolonging life, as well as an ambivalent attitude towards legal regulations binding in Poland.

Broad areas of astrophysics are covered and the level of astronomical research in Poland is higher than the world average. Joining ESO has created an atmosphere that is conducive to further improvements in the quality of Polish research, and it marks an important step towards the full integration of Polish astronomers into the international scientific community.

  19. Information Uncertainty to Compare Qualitative Reasoning Security Risk Assessment Results

    2009-01-01

    The security risk associated with malevolent acts such as those of terrorism are often void of the historical data required for a traditional PRA. Most information available to conduct security risk assessments for these malevolent acts is obtained from subject matter experts as subjective judgements. Qualitative reasoning approaches such as approximate reasoning and evidential reasoning are useful for modeling the predicted risk from information provided by subject matter experts. Absent from these approaches is a consistent means to compare the security risk assessment results. Associated with each predicted risk reasoning result is a quantifiable amount of information uncertainty which can be measured and used to compare the results. This paper explores using entropy measures to quantify the information uncertainty associated with conflict and non-specificity in the predicted reasoning results. The measured quantities of conflict and non-specificity can ultimately be used to compare qualitative reasoning results which are important in triage studies and ultimately resource allocation. Straight forward extensions of previous entropy measures are presented here to quantify the non-specificity and conflict associated with security risk assessment results obtained from qualitative reasoning models.

    Background: Health literacy concerns the capacities of people to meet the complex demands of health in modern society. In spite of the growing attention for the concept among European health policymakers, researchers and practitioners, information about the status of health literacy in Europe remains scarce. This article presents selected findings from the first European comparative survey on health literacy in populations. Methods: The European health literacy survey (HLS-EU) was conducted in eight countries: Austria, Bulgaria, Germany, Greece, Ireland, the Netherlands, Poland and Spain (n = 1000 per country, n = 8000 total sample). Data collection was based on Eurobarometer standards and the implementation of the HLS-EU-Q (questionnaire) in computer-assisted or paper-assisted personal interviews. Results: The HLS-EU-Q constructed four levels of health literacy: insufficient, problematic, sufficient and excellent. At least 1 in 10 (12%) respondents showed insufficient health literacy and almost 1 in 2 (47%) had limited (insufficient or problematic) health literacy. However, the distribution of levels differed substantially across countries (29–62%). Subgroups within the population, defined by financial deprivation, low social status, low education or old age, had higher proportions of people with limited health literacy, suggesting the presence of a social gradient which was also confirmed by raw bivariate correlations and a multivariate linear regression model. Discussion: Limited health literacy represents an important challenge for health policies and practices across Europe, but to a different degree for different countries. The social gradient in health literacy must be taken into account when developing public health strategies to improve health equity in Europe. PMID:25843827

    Only a few studies comparing flea composition on the coast and in the mountains have been conducted. We investigated differences in flea communities infesting small mammals in selected habitats in northern, central, and southern Poland. We predicted (1) a greater number of flea species in the southeastern Poland and a lower number in the north, (2) a greater number of flea species in fertile and wet habitats than in poor and arid habitats, and (3) a low similarity of flea species between flea communities in western and eastern Poland. We found a negative effect of increasing latitude on flea species richness. We suppose that the mountains providing a variety of environments and the limits of the geographic ranges of several flea subspecies in southeastern Poland result in a higher number of flea species. There was a positive effect of increasing wetness of habitat on flea species richness. We found a high diversity in flea species composition between western and eastern Poland (beta diversity = 11) and between central and eastern Poland (beta diversity = 12). Re-colonization of Poland by small mammals and their ectoparasites from different (western and eastern) refugees can affect on this high diversity of flea species. PMID:24619068

    The increasing number of computerised tomography (CT) procedures performed in Poland in recent years has resulted in a growing contribution of these examinations to the whole exposure of the population to ionising radiation from medical sources. (The number of CT examinations in Poland was 170,000 in 1995 and 460,000 in 1999.) An evaluation is presented of doses to patients in CT examinations performed with different types of CT unit. To evaluate the exposure to patients dose linear product (DLP) was measured using a NOMEX dosemeter with a pencil chamber (PTW, Frieburg) and the cylindrical PMMA phantoms 'head' and 'body'. CTDI values were evaluated according to current methodology as described in European Guidelines (EUR 16262). The measurements were performed for seven types of CT unit made by different companies. The CTDI values were also compared to reference levels recommended by IAEA. In conclusion it was found that the value of collective effective dose (2200 man.Sv), has increased in Poland nearly 4 times in comparison to 1995, whereas the number of CT examinations increased nearly 3 times in this period. For most of the 'controlled' CT scanners the values of CTDI in head procedures are near to or higher than the IAEA Reference Level (50 mGy); this can result from the protocols, which are chosen without a dose analysis.

    This paper presents application of satellite interferometric methods (persistent scatterer interferometric synthetic aperture radar (PSInSAR™) and differential interferometric synthetic aperture radar (DInSAR)) for observation of ground deformation in the Upper Silesian Coal Basin (USCB) in Southern Poland. The presented results were obtained during the DORIS project (EC FP 7, Grant Agreement n. 242212, www.doris-project.eu). Several InSAR datasets for this area were analysed. Most of them were processed by Tele-Rilevamento Europa - T.R.E. s.r.l. Italy. Datasets came from different SAR satellites (ERS 1 and 2, Envisat, ALOS- PALSAR and TerraSAR-X) and cover three different SAR bands (L, C and X). They were processed using both InSAR techniques: DInSAR, where deformations are presented as interferometric fringes on the raster image, and PSInSAR, where motion is indentified on irregular set of persistent scatterer (PS) points. Archival data from the C-band European Space Agency satellites ERS and ENVISAT provided information about ground movement since 1992 until 2010 in two separate datasets (1992-2000 and 2003-2010). Two coal mines were selected as examples of ground motion within inactive mining areas: Sosnowiec and Saturn, where mining ceased in 1995 and 1997, respectively. Despite well pumping after closure of the mines, groundwater rose several dozen meters, returning to its natural horizon. Small surface uplift clearly indicated on satellite interferometric data is related to high permeability of the hydrogeological subregion and insufficient water withdrawal from abandoned mines. The older 1992-2000 PSInSAR dataset indicates values of ground motion ranging from -40.0 to 0.0 mm. The newer 2003-2010 dataset shows values ranging from -2.0 to +7.0 mm. This means that during this period of time subsidence was less and uplift greater in comparison to the older dataset. This is even more evident in the time series of randomly selected PS points from both coal

    Dietary investigations in four central European survey populations carried out in the German Democratic Republic, Poland and Denmark between 1982 and 1984 using different methodologies were analysed in order to assess the possibilities of characterizing the dietary habits of individual survey participants in a comparable fashion. This was done with the view of assessing the feasibility of a pooled cancer cohort study. For this purpose a method has been devised to combine dietary information derived by food frequency questionnaires and quantitative recording methods into a quantitative characterization of individuals' habits. A comparable characterization between different cultural settings could be demonstrated for a selected list of food items. The selection was determined by the food items considered in common in the different food frequency questionnaires and yielding sufficient and comparable variation as well as absolute amounts of intake. This was more clearly found for food items such as 'fruit' which experience a concise role in dietary habits. However, the observed discrepancies of the different dietary methods within the countries, and, most importantly, between the countries, result in distributions of average daily consumption values which are not deemed to be comparable.

    Diagnostic tests are traditionally compared for accuracy against a gold standard but can also be compared prospectively in a trial. A conventional trial comparing two tests would randomize each participant to a testing strategy, but a more efficient alternative is to give both tests to all participants and follow up those with discordant results. Participants could be randomized before or after testing. The statistical analysis of such a trial has not previously been described. We investigated two estimates of the risk difference for a binary outcome: one based on analysing outcomes as if from a conventional trial and one combining estimates of different parameters in the manner of a decision analysis. We show that the trial estimate and decision analysis estimate are both unbiased and derive approximate formulae for their standard errors. By using the decision analysis estimate (but not the trial estimate), the same precision can be achieved by randomizing before testing as by randomizing after. To avoid destroying equipoise, and to allow consenting and randomizing to be carried out at the same visit, we recommend randomizing before testing. Giving both tests to all participants means fewer need to be recruited: in one example from the literature, the proposed design was nearly four times more efficient in this sense than a conventional trial design.

    The MARIA reactor at the Institute of Atomic Energy (IAE) in Swierk (30 km SE of Warsaw) in the Republic of Poland is considering conversion from high-enriched uranium (HEU) to low-enriched uranium (LEU) fuel assemblies (FA). The FA design in MARIA is rather unique; a suitable LEU FA has never been designed or tested. IAE has contracted with CERCA (the fuel supply portion of AREVA in France) to supply 2 lead test assemblies (LTA). The LTAs will be irradiated in MARIA to burnup level of at least 40% for both LTAs and to 60% for one LTA. IAE may decide to purchase additional LEU FAs for a full core conversion after the test irradiation. The Reactor Safety Committee within IAE and the National Atomic Energy Agency in Poland (PAA) must approve the LTA irradiation process. The approval will be based, in part, on IAE submitting revisions to portions of the Safety Analysis Report (SAR) which are affected by the insertion of the LTAs. (A similar process will be required for the full core conversion to LEU fuel.) The analysis required was established during working meetings between Argonne National Laboratory (ANL) and IAE staff during August 2006, subsequent email correspondence, and subsequent staff visits. The analysis needs to consider the current high-enriched uranium (HEU) core and 4 core configurations containing 1 and 2 LEU LTAs in various core positions. Calculations have been performed at ANL in support of the LTA irradiation. These calculations are summarized in this report and include criticality, burn-up, neutronics parameters, steady-state thermal hydraulics, and postulated transients. These calculations have been performed at the request of the IAE staff, who are performing similar calculations to be used in their SAR amendment submittal to the PAA. The ANL analysis has been performed independently from that being performed by IAE and should only be used as one step in the verification process.

    Recently, horseradish peroxidase (HRP) was immobilized on activated wool and we envisioned that the use of chitosan would be interesting instead of wool owing to its simple chemical structure, abundant nature and biodegradability. In this work, HRP was immobilized on chitosan crosslinked with cyanuric chloride. FT-IR spectroscopy and scanning electron microscopy were used to characterize immobilized HRP. The number of ten reuses of immobilized HRP has been detected. The pH was shifted from 5.5 for soluble HRP to 5.0 for immobilized enzyme. The soluble HRP had an optimum temperature of 30 °C, which was shifted to 35 °C for immobilized enzyme. The soluble HRP and immobilized HRP were thermal stable up to 35 and 45 °C, respectively. The apparent kinetic constant values (K(m)) of soluble HRP and chitosan-HRP were 35 mM and 40 mM for guaiacol and 2.73 mM and 5.7 mM for H2O2, respectively. Immobilization of HRP partially protected them from metal ions compared to soluble enzyme. The chitosan-HRP was remarkably more stable against urea, Triton X-100 and organic solvents. Chitosan-HRP exhibited large number of reuses and more resistance to harmful compounds compared with wool-HRP. On the basis of results obtained in the present study, chitosan-HRP could be employed in bioremediation application. PMID:23769933

    Data compression is very necessary in business data processing, because of the cost savings that it offers and the large volume of data manipulated in many business applications. It is a method or system for transmitting a digital image (i.e., an array of pixels) from a digital data source to a digital data receiver. More the size of the data be smaller, it provides better transmission speed and saves time. In this communication, we always want to transmit data efficiently and noise freely. This paper will provide some compression techniques for lossless text type data compression and comparative result of multiple and single compression, that will help to find out better compression output and to develop compression algorithms.

    Comparative risk assessment (CRA) is a systematic procedure for evaluating the environmental problems affecting a geographic area. This paper looks beyond the U.S. border and examines the experience with CRAs conducted in various developing countries and economies in transition, including Bangkok, Thailand, Cairo, Egypt and Quito, Ecuador, as well as other locations in Eastern Europe, Asia and Central and South America. A recent pilot CRA conducted in Taiwan is also considered. Comparisons are made of both the methodologies and the results across the relatively diverse international literature. The most robust finding is that conventional air pollutants (e.g., particulate matter and lead) consistently rank as high health risks across all of the CRAs examined. Given the varied nature of the settings studied in the CRAs, including level of economic development, urban-rural differences, and climate, this finding is particularly significant. Problems involving drinking water are also ranked as a high or medium health risk in almost all the countries studied. This is consistent with the results of analyses conducted by the World Bank suggesting contamination, limited coverage and erratic service by water supply systems. Beyond the major air pollutants and drinking water, the CRA results diverge significantly across countries. A number of problems involving toxic chemicals, e. g., hazardous air pollutants, rank as high health risks in the US but do not appear as consistent areas of concerns in the other countries studied. This likely reflects the so-called "risk transition" - the shift from sanitation and infection disease problems to those involving industry, vehicles and toxic substances - that often occurs with economic development. It may also reflect the greater information about sources of toxic pollutants in the U.S. For other problems, there are important differences across the developing countries and economies in transition. For example, hazardous and

    Validation of SMOS products is vital for their further use in the study of climate and hydrology. Several authors [1,2] have recently evaluated SMOS soil moisture data with an aid of in-situ observations of soil moisture. Collow and Robock have reported a dry bias as compared to in situ observations. Since their results are not much conclusive, they call for further studies using more data. Bircher and co-authors have also noted significant discrepancies between Danish network and SMOS soil moisture. SWEX_POLAND soil moisture network consists of 9 stations located in Eastern Poland. These stations are located on the areas representing variety types of land use: meadows, cultivated fields, wetlands and forests. We have expanded our analysis, as presented in the EGU 2012, using data from all network stations. Similarly as before, we have used three methods in our comparison studies: the Bland-Altman method, concordance correlation coefficient and total deviation index. Using these methods we have confirmed a fair/moderate agreement of SMOS L2 SM data and network observations. Like the other authors we have also noted the significant biases in SMOS soil moisture. However, the general trends in dynamics of soil moisture revealed by SMOS, the SWEX_POLAND network and referred to GLDAS, are in a considerable relevancy. We have shown that the SMOS satellite measurements are reliable, so can be used to detect areas of dry and moist soil. In Poland the trends indicating the growth of agricultural droughts are depicted by SMOS L2 very well, even better than national drought services for the agriculture. It is worth to note that the year 2011 was more variable and drier than the 2010 for Poland. Moreover, SMOS data prove the well-known property of central Poland to be drier than the rest of the country. It is expected that further mitigation of RFI contamination in Poland will be available due to the cooperation of ESA SMOS to the national spectrum control services (UKE

  17. The NOD2 3020insC Mutation in Women with Breast Cancer from the Bydgoszcz Region in Poland. First Results

    PubMed Central

    2006-01-01

    The frameshift NOD2 gene mutation 3020insC is predominantly associated with Crohn's disease, but predisposes to many types of common cancers as well. We studied the frequency of this mutant NOD2 allele in 148 breast cancer women from the Bydgoszcz region in Poland. The NOD2 mutation was present in 8.8% of the patients. The mean age at breast cancer diagnosis of the mutation carriers was 43 years. We did not find any mutation in patients diagnosed with breast cancer after the age of 50 years. There was no association of the NOD2 mutation with a strong family history of breast cancer. On the contrary, the mutation frequency (11.4%) was two times higher in women from families with a single case of breast cancer and with aggregation of other common types of cancer, especially digestive tract cancers. Low risk of breast cancer in the mutation carriers seems to be confirmed by finding the 3020insC mutation in three healthy parents of probands aged 73, 74 and 83 years, from three separate families.

  18. Direct anterior total hip arthroplasty: Comparative outcomes and contemporary results

    Connolly, Keith P; Kamath, Atul F

    2016-01-01

    Direct anterior total hip arthroplasty has become increasingly more popular among arthroplasty surgeons, in large part due to the use of an intramuscular interval and desire to reduce soft tissue damage. Several studies have now been published comparing the anterior intramuscular to other commonly used approaches, and many studies have published complication rates on large series of patients. Review of comparative studies indicates direct anterior hips tend towards shorter hospital stays and high rates of patients discharged to home. Although some studies show evidence of early benefit in functional outcomes, there is no strong evidence that the anterior approach provides any long term functional improvements compared to other approaches. Additionally, evidence to support reduced damage to soft tissue may not translate to certain clinical significance. Rates of intra-operative femur fracture, operative time and blood loss rates are notably higher for those developing familiarity with this approach. However, when surgeons have performed a modest number of procedures, the complication rates tend to markedly decrease in most studies to levels comparable to other approaches. Accuracy of component positioning also favors the anterior approach in some studies. This review summarizes the available literature comparing the direct anterior to other approaches for total hip arthroplasty and provides a comprehensive summary of common complications.

    Introduction Comparing results of representative surveys conducted in different East-European countries could contribute to a better understanding and management of cardiovascular risk factors, offering grounds for the development of health policies addressing the special needs of this high cardiovascular risk region of Europe. The aim of this paper was to describe the methodology on which the comparison between the Romanian survey SEPHAR II and the Polish survey NATPOL 2011 results is based. Material and methods SEPHAR II, like NATPOL 2011, is a cross-sectional survey conducted on a representative sample of the adult Romanian population (18 to 80 years) and encompasses two visits with the following components: completing the study questionnaire, blood pressure and anthropometric measurements, and collection of blood and urine samples. Results From a total of 2223 subjects found at 2860 visited addresses, 2044 subjects gave written consent but only 1975 subjects had eligible data for the analysis, accounting for a response rate of 69.06%. Additionally we excluded 11 subjects who were 80 years of age (NATPOL 2011 included adult subjects up to 79 years). Therefore, the sample size included in the statistical analysis is 1964. It has similar age groups and gender structure as the Romanian population aged 18–79 years from the last census available at the moment of conducting the survey (weight adjustments for epidemiological analyses range from 0.48 to 8.7). Conclusions Sharing many similarities, the results of SEPHAR II and NATPOL 2011 surveys can be compared by a proper statistical method offering crucial information regarding cardiovascular risk factors in a high-cardiovascular risk European region.

  20. Poland's syndrome revisited.

    2002-12-01

    Poland's syndrome is a rare congenital anomaly characterized by unilateral chest wall hypoplasia and ipsilateral hand abnormalities. Literary data suggest its sporadic nature. The prevailing theory of its cause is hypoplasia of the subclavian artery or its branches, which may lead to a range of developmental changes. The incidence of Poland's syndrome varies between groups (male versus female patients, congenital versus familial cases, and so on) and ranges from 1 in 7,000 to 1 in 100,000 live births. Cases of Poland's syndrome associated with leukemia, carcinoma of the hypoplastic breast, and other conditions, confirm the relationship between developmental defects and tumors, and require oncologic awareness. Various manifestations, age, and gender require different surgical approaches. Our experience, which includes 27 patients (15 male, 12 female), 20 of whom (12 male, 8 female) underwent operation, suggests that the repair should be done in two stages in children and in a single stage in adults. Reconstruction and/or stabilization of the aplastic ribs may be achieved using bone grafts or prosthetic mesh. Muscle flaps and breast implants may be used to correct muscle deficiency and breast hypoplasia and to help achieve a complete cosmetic repair. PMID:12643435

    Background Several factors, which are components of pharmaceutical care, can influence a patient’s choice of a community pharmacy store and contribute to frequent visits to the same pharmacy. Objectives To compare factors that influence a patient’s choice of pharmacy in Poland and in the UK, to identify which of them are components of pharmaceutical care, and to relate them to patient loyalty to the same pharmacy. Methods A self-administered, anonymous questionnaire was distributed to clients visiting pharmacies in Poland and the UK January–August 2011. Comparisons were performed using chi-square tests and logistic regression. All statistical analyses were performed using SPSS 20.0. Results The response rate was 55.6% (n=417/750; 36 pharmacies) and 54.0% (n=405/750; 56 pharmacies) in Poland and in the UK, respectively. The most frequently reported factors, as defined by a percentage of responders, were in Poland: 1) location (84%); 2) professional and high-quality of service (82%); 3) good price of medicines (78%); and 4) promotions on medicines (66%). In the UK, the most commonly reported factors were: 1) professional and high quality of service (90%); 2) location (89%); 3) good advice received from the pharmacist (86%); and 4) option of discussing and consulting all health issues in a consultation room (80%). Good advice and an option of discussing personal concerns with a pharmacist are components of pharmaceutical care. Thirty-eight percent of patients in Poland and 61% in the UK declared visiting the same pharmacy. Conclusion Components of pharmaceutical care are important factors influencing the patient’s choice of pharmacy in the UK and, to a lesser degree, in Poland. Additionally, more patients in the UK than in Poland are committed to a single pharmacy. Therefore, implementing the full pharmaceutical care in Poland may contribute to an increase in patient loyalty and thus strengthen competitiveness of pharmacy businesses. PMID:24868150

    We describe a collaborative effort between the U.S., India, and Poland to track acute chemical releases during 2005–2007. In all three countries, fixed facility events were more common than transportation-related events; manufacturing and transportation/warehousing were the most frequently involved industries; and equipment failure and human error were the primary contributing factors. The most commonly released nonpetroleum substances were ammonia (India), carbon monoxide (U.S.) and mercury (Poland). More events in India (54%) resulted in victims compared with Poland (15%) and the U.S. (9%). The pilot program showed it is possible to successfully conduct international surveillance of acute hazardous substances releases with careful interpretation of the findings. PMID:19826549

    The aim of the presentation is to show the suitability of using numerical model wind speed forecasts for the wind power industry applications in Poland. In accordance with the guidelines of the European Union, the consumption of wind energy in Poland is rapidly increasing. According to the report of Energy Regulatory Office from 30 March 2013, the installed capacity of wind power in Poland was 2807MW from 765 wind power stations. Wind energy is strongly dependent on the meteorological conditions. Based on the climatological wind speed data, potential energy zones within the area of Poland have been developed (H. Lorenc). They are the first criterion for assessing the location of the wind farm. However, for exact monitoring of a given wind farm location the prognostic data from numerical model forecasts are necessary. For the practical interpretation and further post-processing, the verification of the model data is very important. Polish Institute Meteorology and Water Management - National Research Institute (IMWM-NRI) runs an operational model COSMO (Consortium for Small-scale Modelling, version 4.8) using two nested domains at horizontal resolutions of 7 km and 2.8 km. The model produces 36 hour and 78 hour forecasts from 00 UTC, for 2.8 km and 7 km domain resolutions respectively. Numerical forecasts were compared with the observation of 60 SYNOP and 3 TEMP stations in Poland, using VERSUS2 (Unified System Verification Survey 2) and R package. For every zone the set of statistical indices (ME, MAE, RMSE) was calculated. Forecast errors for aerological profiles are shown for Polish TEMP stations at Wrocław, Legionowo and Łeba. The current studies are connected with a topic of the COST ES1002 WIRE-Weather Intelligence for Renewable Energies.

    While the world has yet to adopt a single unified policy to limit climate change, many countries and regions have adopted energy and climate policies that have implications for global emissions. In this paper, we discuss a few key policies and how they are included in a set of 24 energy and integrated assessment models that participated in the Asia Modeling Exercise. We also compare results from these models for a small set of stylized scenarios to the pledges made as part of the Copenhagen Accord and the goals stated by the Major Economies Forum. We find that the targets outlined by the United States, the European Union, Japan, and Korea require significant policy action in most of the models analyzed. For most of the models in the study, however, the goals outlined by India are met without any climate policy. The stringency of climate policy required to meet China’s Copenhagen pledges varies across models and accounting methodologies.

    This paper presents the results of tests conducted to determine the effect of the constructional elements of a Laval nozzle on the velocity and pressure distribution and the magnitude of the reaction force of the jet. The effect was studied of the shapes of the entrance section of the nozzle and three types of divergent sections: namely, straight cone, conoidal with cylindrical and piece and diffuser obtained computationally by a graphical method due to Professor F. I. Frankle. The effect of the divergence angle of the nozzle on the jet reaction was also investigated. The results of the investigation showed that the shape of the generator of the inner surface of the entrance part of the nozzle essentially has no effect on the character of the flow and on the reaction. The nozzle that was obtained by graphical computation assured the possibility of obtaining a flow for which the velocity of all the gas particles is parallel to the axis of symmetry of the nozzle, the reaction being on the average 2 to 3 percent greater than for the usual conical nozzle under the same conditions, For the conical nozzle the maximum reaction was obtained for a cone angle of 25deg to 27deg. At the end of this paper a sample computation is given by the graphical method. The tests were started at the beginning of 1936 and this paper was written at the same time.

    2014-05-01

    In January 2014 Head Office of Geodesy and Cartography, Polish authority for geodesy and cartography, has released transformation models for position and height. The appearance of the models is related to changes in legal acts concerning the introduction of new reference system and frames used in Poland. The transformation models link old reference frames PL-ETRF89-GRS80h (also called EUREF-89) and PL-KRON86-NH with new realizations PL-ETRF2000- GRS80h and PL-EVRS2007-NH. The reference frame for position is expressed in the same reference system ETRS89. In case of height system Poland is currently switching form Kronstadt normal height system to EVRS - European height system referred to the Normaal Amsterdams Peil. The transformation models are based on grids covering territory of Poland with node spacing of 0.01 of degree. Model for transformation between previous and current ETRS89 realizations is based on the results of GNSS calibration campaign conducted between 2008 and 2011, covering over 500 points (permanent reference stations and 1st order ground control points) regularly distributed over interest area. Above transformation model has been analyzed in the context of differences to previous frames realizations and to the approach based on parameter transformation. In the context of implementation of EVRF2007 the new local quasi-geoid model PL-geoid-2011 has been compared to the latest geopotential model, European quasi-geoid models EGG and local quasi-geoid models used so far. In addition the new model has been confronted with undulations based on the existing satellite levelling data, including the results of the fourth leveling campaign.

    2015-09-01

    The area of contact between Precambrian and Phanerozoic Europe in Poland has complicated structure of sedimentary cover and basement. The thinnest sedimentary cover in the Mazury-Belarus anteclize is only 0.3-1 km thick, increases to 7-8 km along the East European Craton margin, and 9-12 km in the Trans-European Suture Zone (TESZ). The Variscan domain is characterized by a 1- to 2-km-thick sedimentary cover, while the Carpathians are characterized by very thick sediments, up to c. 20 km. The map of the basement depth is created by combining data from geological boreholes with a set of regional seismic refraction profiles. These maps do not provide data about the basement depth in the central part of the TESZ and in the Carpathians. Therefore, the data set is supplemented by 32 models from deep seismic sounding profiles and a map of a high-resistivity (low-conductivity) layer from magnetotelluric soundings, identified as a basement. All of these data provide knowledge about the basement depth and of P-wave seismic velocities of the crystalline and consolidated type of basement for the whole area of Poland. Finally, the differentiation of the basement depth and velocity is discussed with respect to geophysical fields and the tectonic division of the area.

    The purpose here is to contribute to the discussion surrounding the use of community benefits (also known as added value) in radioactive waste facility siting programmes. These are becoming more widely used following a series of programme failures around the world, due in the main to a lack of local involvement. A number of different models for the use of community benefits and why they may or may not assist a siting process exist in the literature, based on either a voluntary market approach or one involving coercion by a state authority or developer. Review of real-life examples suggests that two main approaches to the use of benefits exist, a 'legally-mandated' approach where details are laid down in legislation, and a 'locally-negotiated' approach where the details are agreed by the parties through discussions. As part of the European Commission supported IPPA project (Implementing Public Participation Approaches in Radioactive Waste Disposal), stakeholder groups in three participant countries, the Czech Republic, Poland and Slovenia, all of which currently utilise the 'legally-mandated' approach to the provision of community benefits, were invited to respond to a series of questions designed to explore their attitudes and thoughts about the two approaches and related issues such as trust in the institutions and the legal framework. Some initial results and conclusions are presented, although this work is continuing and will be reported at the end of the IPPA project in 2013. (authors)

    In order to elucidate the clinical homogeneity and severity of the hyperphenylalaninaemias in Poland, a total of 71 children with typical phenylketonuria (PKU) originating from western and northern Poland were screened for 13 mutations in the phenylalanine hydroxylase (PAH) gene. Eighty percent of all PKU alleles tested were found to carry an identified mutation. One mutation, namely the R408W mutation, accounted for more than 63% of mutant PAH alleles in Poland, the other 27% being accounted for by six mutations: IVS12nt1 (5%), IVSnt546 (5%), Y414C (4%), R252W (1.5%), R261Q (< 1%), and G272ter (< 1%). The predominance of the R408W mutation resulted in a high rate of homozygotes (35.2%) and compound heterozygotes for this mutation in children from western and northern Poland. The frequency and deleterious nature of this mutation probably accounts for the clinical homogeneity and severity of the hyperphenylalaninaemias in Poland. In addition, the high rate of the R408W mutation and its association with mutant haplotype 2 at the PAH locus in Poland give additional support to the Balto-Slavic origin of this mutant gene.

    Poland and Albania, respectively the first and last European countries to emerge from Communist rule, have unveiled bidding rounds for oil and gas projects. This paper reports that the goal is to encourage foreign investment in exploration and development. Poland's ministry of Environmental Protection, Natural Resources and Forestry, Warsaw, announced the schedule for its first bidding round for coalbed methane exploration licenses. Site is the Upper Silesian coal basin. Oil and gas companies were invited to submit proposals by Oct. 1 to develop what the ministry says is one of the world's most commercially viable coalbed methane resource. Five data packages are available covering 11 blocks. Packages cost $20,000 each or in combinations as much as $70,000 for all five. They include geological data, maps, gas transmission infrastructure details, drilling data, and results of coalbed methane studies. A bid is eligible only if the bidder has bought the relevant data package.

    The objective of the study was determination of experiment-induced alterations and changes in the properties of reservoir rocks and sealing rocks sampled from potential reservoir for CO₂. In the experiment, rocks submerged in brine in specially constructed reactors were subjected to CO₂ pressure of 6 MPa for 20 months at room temperature. Samples of Lower Jurassic reservoir rocks and sealing rocks (sandstones, claystones, and mudstones) from the Zaosie Anticline (central Poland) were analysed for their petrophysical properties (specific surface area, porosity, pore size and distribution) before and after the experiment. Comparison of the ionic composition the brines before and after the experiment demonstrated an increase in total dissolved solids as well as the concentration of sulphates and calcium ions. This indicates partial dissolution of the rock matrix and the cements. As a result of the reaction, the properties of reservoir rocks did not changed significantly and should not affect the process of CO₂ storage. In the case of the sealing rocks, however, the porosity, the framework density, as well as the average capillary and threshold diameter increased. Also, the pore distribution in the pore space changed in favour of larger pores. The reasons for these changes could not be explained by petrographic characteristics and should be thoroughly investigated. PMID:25519873

  14. [Social aspect of clinical research in Poland].

    Each year more than 400 new clinical studies are registered in Poland. They gather above 50.000 of study participants. Social opinion on clinical trials is an important factor. The paper presents the review of actual opinions on clinical research in Poland. It provides the description of standards of protection of study participants, benefits and risks related to the participation in clinical research and the role of media in creating and influencing of the social perception of clinical trials. Results of conducted questionnaire studies imply that Poles correctly identify and assess the risk of participation in clinical experiments. The primary reason for the participation seams to be the possibility to help other patients, contribution to the progress of science and standards of medical care and potential benefits for other sufferers. The need of testing the safety and efficacy of the new medication in man is generally well recognized. At the same time a substantial part of the society is concerned with the possible corruption of investigators and unethical behaviour of sponsors. The social perception of clinical research in Poland is in majority of analyzed parameters not substantially different from opinions in other member states of EU. However, the medical society should be more active in influencing and changing some negative impressions. PMID:18432135

    Since the successful transition to a freely elected parliament and a market economy after 1989, Poland is now a stable democracy and is well represented within political and economic organizations in Europe and worldwide. The strongly centralized health system based on the Semashko model was replaced with a decentralized system of mandatory health insurance, complemented with financing from state and territorial self-government budgets. There is a clear separation of health care financing and provision: the National Health Fund (NFZ) the sole payer in the system is in charge of health care financing and contracts with public and non-public health care providers. The Ministry of Health is the key policy-maker and regulator in the system and is supported by a number of advisory bodies, some of them recently established. Health insurance contributions, borne entirely by employees, are collected by intermediary institutions and are pooled by the NFZ and distributed between the 16 regional NFZ branches. In 2009, Poland spent 7.4% of its gross domestic product (GDP) on health. Around 70% of health expenditure came from public sources and over 83.5% of this expenditure can be attributed to the (near) universal health insurance. The relatively high share of private expenditure is mostly represented by out-of-pocket (OOP) payments, mainly in the form of co-payments and informal payments. Voluntary health insurance (VHI) does not play an important role and is largely limited to medical subscription packages offered by employers. Compulsory health insurance covers 98% of the population and guarantees access to a broad range of health services. However, the limited financial resources of the NFZ mean that broad entitlements guaranteed on paper are not always available. Health care financing is overall at most proportional: while financing from health care contributions is proportional and budgetary subsidies to system funding are progressive, high OOP expenditures

  16. Length and terms of occurrence of thermal seasons in Poland - are any changes observed?

    While thinking of seasons, one mostly has in mind astronomical seasons which are very often mentioned by media. These are set using Sun's position above the equator and the tropics. Seasons defined by these manners very frequently do not match with prevailing climatic conditions in Poland. Therefore, especially in scientific research, different ways of setting the beginning and ending of seasons in Poland are employed. Climatic seasons are used very broadly. They divide the year into four parts of almost equal duration. Nevertheless, for Poland, this method is also not fully representative, because it does not take into account regional differentiation of climatic conditions. More objective criteria are used in phenological seasons, where their duration is set by, for example the terms of florescence and maturation of plants. In this research, thermal criterion is applied for setting the duration of seasons - terms of persistent exceedances of characteristic thresholds of mean daily air temperature (5 degrees C for autumn and spring, 0 degrees C for winter and 15 degrees C for summer). The climate of Poland is characterised by large long-term variability of thermal conditions. It results in the possibility of evident differences in the length and terms of seasons beginning and ending between years. The winter season 2012/2013 in Poland was exceptionally long, and very low temperatures occurred during the whole March, even in the first decade of April in some parts of the country. At the same year at the end of April temperatures exceeded 20 degrees C (summer conditions). It resulted in another wide discussion on evident changes of length or even fading of some seasons in the media. Based on meteorological data from 10 Polish meteorological stations, that represent different regions of the country, authors are researching how the length of thermal seasons changed between years 1951 and 2013 in Poland.

    Background. We compared the public perception of cancer care in Poland and Austria. Both countries are members of the European Union (EU) but reflect two extremes in health-related per capita spending. Recently, the EUROCARE-5 study reported on very discrepant cancer outcomes between the two countries. Methods. A one-time survey was conducted to compare the public perception of cancer treatment in Poland and Austria. In total, 3,649 subjects, representing the general population, cancer patients, and cancer patients’ family members, were surveyed. Results. In both countries, cancer was considered the most challenging problem of the health care system, and health care was indicated as the most important issue influencing political election decisions. Polish compared with Austrian cancer patients gave a significantly lower positive assessment of overall cancer treatment efficacy and detection methods. Cancer cure rates estimated by Polish and Austrian citizens were 29% and 44%, respectively. The majority of all citizens interviewed thought that cancer patients should have access to all available registered cancer drugs. However, only 18% of Poles versus 62% of Austrians agreed with the notion that the available cancer treatment in their countries is of a standard comparable to that of other EU countries. Consequently, 24% of Poles and 7% of Austrians identified financial status, age, gender, and residence as factors influencing the availability of cancer treatments. Conclusion. In both countries, cancer is considered the most challenging problem of the health care system, and health care issues may strongly influence decisions for political elections. Vast differences in the two populations’ perceptions of cancer care reflect actual cancer outcomes and the national per capita spending on health-related issues. PMID:25520325

    Fowl adenoviruses (FAdVs) are widely distributed in chickens in Poland and throughout the world. FAdV infections have been reported in the United States, Australia, Europe, and the Mediterranean basin. Detection of FAdVs strains is very important from the epidemiological point of view and for monitoring disease outbreaks and developing strategies for vaccine development. Several molecular epidemiology and phylogenetic studies have been performed, but the results obtained are still limited, because FAdV strains, even of the same serotype, have very diverse characteristics. Some strains are pathogenic and some are nonpathogenic. This report describes the successful isolation of 96 FAdV field strains from chickens in Poland. A PCR assay specific for the L1 loop region of the hexon gene was conducted, and the products were subjected to sequence analysis. The sequences were analysed using BLAST and Geneious 6.0 software and compared to adenovirus field and reference strain sequences from different parts of the world that are accessible in the NCBI GenBank database. The sequences of the adenovirus strains indicated that they belonged to five species, Fowl aviadenovirus A-E, represented by eight serotypes FAdV-1, FAdV-4, FAdV-5, FAdV-7, FAdV-8a, FAdV-8b, and FAdV-2/11 (FAdV-D). The relationships between FAdVs isolated in Poland and isolates from other regions of the world were determined. PMID:26446890

    Tritrichomonas foetus, a parasite of cattle reproductive system, has been recently discovered as a cause of disease in cats in many countries. T. foetus infects and colonizes cat's ileum, caecum, colon and can lead to enteritis. This paper presents the first clinical case of cat intestinal trichomonosis caused by T. foetus in Poland. The material for this study was a smear collected from a 6-month-old male British Shorthair cat. The presence of parasitic protozoan was determined via microscopic examination and confirmed by amplification of T. foetus rDNA using polymerase chain reaction (PCR) technique. In the first PCR reaction, a DNA of Trichomonadidae was identified and in the second PCR, T. foetus was detected. The T. foetus positive products from the second PCR reaction were sequenced. Interpretation of the sequencing results of obtained amplicons by comparing them with the GenBank database proved that the causative agent, in this case, was T. foetus. PMID:26408578

    Postponing motherhood is a widespread phenomenon across developed countries, however only few studies look into very late motherhood in post-socialist countries using individual level data. In this study, I look at the context of the first childbirth in Poland in the midst of the political transformation of 1989. Employing sequence analysis I reconstructed life trajectories of women who experienced the transition to adulthood during the late 1980's and the early 1990's and have just completed their fertility histories. Individual data from the 2011 GGS-PL and the 2011 FAMWELL Survey were used. Comparing paths of mothers’ lives, I searched for differences in educational, professional and conjugal careers between women who gave birth before the age of 30 and after the age of 35. The results show how various life careers crisscross over the life course leading women to late motherhood. PMID:25641993

  1. Mercury emission from coal-fired power plants in Poland

    NASA Astrophysics Data System (ADS)

    Glodek, Anna; Pacyna, Jozef M.

    The paper reviews the current state of knowledge regarding sources of mercury emission in Poland. Due to the large quantities of coal burned at present, as well as taking into account existing reserves, coal remains the main energy source of energy in Poland. The data on coal consumption in Poland in the past, at present and in the future are discussed in the paper. Information on the content of mercury in Polish coals is presented. Coal combustion processes for electricity and heat production are the main source of anthropogenic mercury emission in Poland. It is expected that the current emissions will decrease in the future due to implementation of efficient control measures. These measures for emission reduction are described in the paper. Results of estimated mercury emission from coal-fired power station situated in the Upper Silesia Region, Poland are investigated. A relationship between mercury emission to the air and the mercury content in the consumed coal in power station equipped with the electrostatic precipitators (ESPs) is discussed.

  2. Very large hail occurrence in Poland from 2007 to 2015

    Very large hail is known as a presence of a hailstone greater or equal to 5 cm in diameter. This phenomenon is rare but its significant consequences, not only to agriculture but also to automobiles, households and people outdoor makes it essential thing to examine. Hail appearance is strictly connected with storms frequency and its kind. The most hail-endangered kind of storm is supercell storm. Geographical distribution of hailstorms was compared with geographical distribution of storms in Poland. Similarities were found. The area of the largest number of storms is southeastern Poland. Analyzed European Severe Weather Database (ESWD) data showed that most of very large hail reports occurred in this part of Poland. The probable reason for this situation is the longest period of lasting tropical airmasses in southeastern Poland. Spatial distribution analysis shows also more hail incidents over Upper Silesia, Lesser Poland, Subcarpathia and Świętokrzyskie regions. The information source about hail occurrence was ESWD - open database, where everyone can add report and find reports which meet given search criteria. 69 hailstorms in the period of 2007 - 2015 were examined. They caused 121 very large hail reports. It was found that there is large disproportion in number of hailstorms and hail reports between individual years. Very large hail season in Poland begins in May and ends in September with cumulation in July. Most of hail occurs between 12:00 and 17:00 UTC, but there were some cases of very large (one extremely large) hail at night and early morning hours. However very large hail is a spectacular phenomenon, its local character determines potentially high information loss rate and it is the most significant problem in hail research.

    We evaluated helminth parasites of the introduced North American raccoon ( Procyon lotor L.) in Poland. From June 2006 to May 2007, 91 raccoon fecal samples were collected in the Warta Mouth National Park situated in western Poland near the Polish-German border. Coprological analyses involved flotation and sedimentation. In total, 7 helminth taxa were identified in the feces: Ancylostoma spp., Baylisascaris procyonis, Capillariidae, Placoconus lotoris, Spirocerca lupi, Strongyloides procyonis, and Echinostoma sp. The parasite assemblage in the raccoon exhibited a low diversity. The results were compared with data from other European and North American studies and suggest a lower prevalence of parasites in newly invaded areas, compared with earlier invaded areas or the native range.

    The paper presents results on 210Po activity concentration measured in mushroom samples collected in northern Poland (Białogard and Elblag areas). Among 20 species of wild mushrooms, King Bolete (Boletus edulis), accumulated 210Po in the highest degree. Therefore this species of higher mushrooms is an excellent bioindicator for 210Po radioactivity in the land environment. Finally, the effective dose of polonium emission was calculated for a consumer of King Bolete. Wild mushroom consumption contributed up to 37 microSv to the effective dose in an individual consuming about 5 kg (fresh weight) of heavily contaminated Boletus edulis species per year.

    2012-04-01

    Weather forecast accuracy has increased in recent times mainly thanks to significant development of numerical weather prediction models. Despite the improvements, the forecasts should be verified to control their quality. The evaluation of forecast accuracy can also be an interesting learning activity for students. It joins natural curiosity about everyday weather and scientific process skills: problem solving, database technologies, graph construction and graphical analysis. The examination of the weather forecasts has been taken by a group of 14-year-old students from Bierun (southern Poland). They participate in the GLOBE program to develop inquiry-based investigations of the local environment. For the atmospheric research the automatic weather station is used. The observed data were compared with corresponding forecasts produced by two numerical weather prediction models, i.e. COAMPS (Coupled Ocean/Atmosphere Mesoscale Prediction System) developed by Naval Research Laboratory Monterey, USA; it runs operationally at the Interdisciplinary Centre for Mathematical and Computational Modelling in Warsaw, Poland and COSMO (The Consortium for Small-scale Modelling) used by the Polish Institute of Meteorology and Water Management. The analysed data included air temperature, precipitation, wind speed, wind chill and sea level pressure. The prediction periods from 0 to 24 hours (Day 1) and from 24 to 48 hours (Day 2) were considered. The verification statistics that are commonly used in meteorology have been applied: mean error, also known as bias, for continuous data and a 2x2 contingency table to get the hit rate and false alarm ratio for a few precipitation thresholds. The results of the aforementioned activity became an interesting basis for discussion. The most important topics are: 1) to what extent can we rely on the weather forecasts? 2) How accurate are the forecasts for two considered time ranges? 3) Which precipitation threshold is the most predictable? 4) Why

    The objective of this study was to assess the transformation of precipitation in terms of quantity and chemical composition following contact with the crown layer in tree stands with varied species composition, to investigate the effect of four predominant forest-forming species (pine, spruce, beech, and oak) on the amount and composition of precipitation reaching forest soils, and to determine the sources of pollution in atmospheric precipitation in forest areas in Poland. The amount and chemical composition (pH, electric conductivity, alkalinity, and chloride, nitrate, sulfate, phosphate, ammonium, calcium, magnesium, sodium, potassium, iron aluminum, manganese, zinc, copper, total nitrogen, and dissolved organic carbon contents) of atmospheric (bulk, BP) and throughfall (TF) precipitation were studied from January to December 2010 on twelve forest monitoring plots representative of Polish conditions. The study results provided the basis for the determination of the fluxes of pollutants in the forest areas of Poland and allowed the comparison of such fluxes with values provided in the literature for European forest areas. The transformation of precipitation in the canopy was compared for different tree stands. The fluxes of substances in an open field and under canopy were influenced by the location of the plot, including the regional meteorological conditions (precipitation amounts), vicinity of the sea (effect of marine aerosols), and local level of anthropogenic pollution. Differences between the plots were higher in TF than in BP. The impact of the vegetation cover on the chemical composition of precipitation depended on the region of the country and dominant species in a given tree stand. Coniferous species tended to cause acidification of precipitation, whereas deciduous species increased the pH of TF. Pine and oak stands enriched precipitation with components that leached from the canopy (potassium, manganese, magnesium) to a higher degree than spruce and

    In this study we assessed the genomic stability of Mycobacterium bovis BCG Moreau seed lots used in Poland for BCG vaccine production since 1955 by pulsed field gel electrophoresis (PFGE), amplified fragment length polymorphism (AFLP) and random amplification of polymorphic DNA (RAPD). BCG vaccine lots were more closely related the original lot -M. bovis BCG Rio de Janeiro Moreau compared with seeds used before 1980, which is consistent with seed lot distribution recorded in the archives. We confirmed the presence of RD8, RD2, senX3-regX3, RD14, DU2-I, whiB3, trcR, the second copy of IS6110 inserted in the promoter region of phoP, mutation D322G in phoR, ΔRD1, and ΔfadD26-ppsA in M. bovis BCG Moreau used for BCG production in Poland. However, unlike the Rio de Janeiro parent BCG, the BCG Moreau substrain used in Poland does not harbour a deletion in Rv3887c, a region that is involved in the membrane transport protein that is part of the ESX-2 type VII secretion system. Differences in the distribution of BCG Moreau for its subsequent use for manufacturing influenced the microevolution of BCG Moreau used in Brazil and Poland. PMID:22749596

    Forests provide important ecosystem services, and protected areas around the world are intended to reduce human disturbance on forests. The question is how forest cover is changing in different parts of the world, why some areas are more frequently disturbed, and if protected areas are effective in limiting anthropogenic forest disturbance. The Carpathians are Eastern Europe's largest contiguous forest ecosystem and are a hotspot of biodiversity. Eastern Europe has undergone dramatic changes in political and socioeconomic structures since 1990, when socialistic state economies transitioned toward market economies. However, the effects of the political and economic transition on Carpathian forests remain largely unknown. Our goals were to compare post-socialist forest disturbance and to assess the effectiveness of protected areas in the border triangle of Poland, Slovakia, and Ukraine, to better understand the role of broadscale political and socioeconomic factors. Forest disturbances were assessed using the forest disturbance index derived from Landsat MSS/TM/ETM+ images from 1978 to 2000. Our results showed increased harvesting in all three countries (up to 1.8 times) in 1988-1994, right after the system change. Forest disturbance rates differed markedly among countries (disturbance rates in Ukraine were 4.5 times higher than in Poland, and those in Slovakia were 4.3 times higher than in Poland), and in Ukraine, harvests tended to occur at higher elevations. Forest fragmentation increased in all three countries but experienced a stronger increase in Slovakia and Ukraine (approximately 5% decrease in core forest) than in Poland. Protected areas were most effective in Poland and in Slovakia, where harvesting rates dropped markedly (by nearly an order of magnitude in Slovakia) after protected areas were designated. In Ukraine, harvesting rates inside and outside protected areas did not differ appreciably, and harvests were widespread immediately before the

    In April 2013, the Laboratory of Geomatics launched the project under the acronym "Bartek 3D" in cooperation with the Research Section of Students from the AGH in Krakow, Pedagogical University and the Jagiellonian University as well. The main aim of the project is to monitor the biggest and probably one of the oldest trees in Poland - Oak Bartek in Zagnańsk (N 50o59'14"; E 20o38'59"), based on multi-temporal Terrestrial Laser Scanning (TLS) technology. One of the results of the project should be a 3D model of Oak Bartek and detection of the changes in the shape of the tree. Terrestrial Laser Scanning and the traditional forest inventory measurements were performed during the Leaf-OFF season in April 2013 and April 2014 and repeated in Leaf-ON period in July 2013 and October 2014 with using scanners: FARO FOCUS 3D, RIEGL VZ-400, LEICA C10 and RevScan (HandyScan). The results based on TLS technology showed some differences comparing to existing data obtained by traditional measurements for forestry inventory: Height (H) of the tree: altimeter Vertex (Haglˆf) H = 29.31 m; HTLS = 28.49 m; Trunk circumference (L) measured with stretched tape: LST = 9.80 m; adjacent along the shape of bark: LT = 13.70 m; TLS measurments: LTLS1/4 = 9.97 m oraz LRevScan = 13.54 m, The average diameter at breast height (DBH130cm) calculated on the basis of 3D basal area of stem DBHTLS1/4 = 3.03 m (DBHT = 3.12 m).

    The aim of the presentation is to analyze if there are any changes in frequency and/or intensity of dry spells in Poland. In recent years precipitation some changes in seasonality of precipitation in Poland were observed, expressing in higher totals in winter and early spring and lower in summer. Together with shorter period with snow cover resulting in smaller water supply at the beginning of vegetation period from snow cover melting and higher temperatures it can cause a serious water deficit. It can exert significant impact on crops. According to 4th IPCC Report more frequent dry spells are probable to increase even in those place where the overall amount of precipitation is not projected to change significantly. Daily precipitation totals from more than 20 stations in Poland were used to distinguish the dry spells and a few indices of dryness were calculated. The spatial and temporal variability of these indices on the area of Poland was analyzed and synoptic scale drivers for prolonged drought events were identified.

    The Goczalkowice Reservoir in the Katowice voivodeship in the Upper Silesia area of Poland. It serves as a major source of water for the population of the Upper Selesia region. In 1987 a major shift took place in the ecology of the reservoir. The shift resulted in major algae blooms which caused problems at the water treatment plant. The primary purpose of the study was to more specifically define the water quality problem of the Goczalkowice Reservoir, to determine it causes and to develop a set of recommendations leading to a solution. The report would then become the basis for proposals for financing of one or more projects needed to implement its recommendations.

    This report provides an analysis of how and why energy use has changed in Poland since the 1970s, with particular emphasis on changes since the country began its transition from a centrally planned to a market economy in 1989. The most important factors behind the large decline in Polish energy use in 1990 were a sharp fall in industrial output and a huge drop in residential coal use driven by higher prices. The structural shift away from heavy industry was slight. Key factors that worked to increase energy use were the rise in energy intensity in many heavy industries and the shift toward more energy intensive modes of transport. The growth in private activities in 1991 was nearly sufficient to balance out continued decline in industrial energy use in that year. We compared energy use in Poland and the factors that shape it with similar elements in the West. We made a number of modifications to the Polish energy data to bring it closer to a Western energy accounting framework, and augmented these with a variety of estimates in order to construct a sufficiently detailed portrait of Polish energy use to allow comparison with Western data. Per capita energy use in Poland was not much below W. European levels despite Poland`s much lower GDP per capita. Poland has comparatively high energy intensities in manufacturing and residential space heating, and a large share of heavy industries in manufacturing output, all factors that contribute to higher energy use per capita. The structure of passenger and freight transportation and the energy intensity of automobiles contribute to lower energy use per capita in Poland than in Western Europe, but the patterns in Poland are moving closer to those that prevail in the West.

  2. Projections of changes of areal evapotranspiration for different land-use units in the Wielkopolska Region (Poland)

    Strong global warming has been observed in the last three decades. Central Europe, including Poland, is not an exception. Moreover, climate projections for Poland foresee further warming as well as changes in the quantity as well as spatial and seasonal distribution of precipitation. This will result in changes in all elements of the water balance, including the areal evapotranspiration. For estimating the areal evapotranspiration, the heat balance method (HBM) is used in this paper for the growing season (March-October), whereas for the remaining months (November-February), evaporation is calculated according to the Ivanov equation. Values of areal evapotranspiration from selected land units are examined and compared for the average conditions in two time horizons, i.e. 1961-1990 (control period) and 2061-2090 (projection horizon) over the Wielkopolska Region in Poland, based on multi-model ensemble climate projections. Projections for the future, based on the MPI-M-REMO model, indicate that the regional average increases of the annual sum of areal evapotranspiration (connected mainly with an increase of air temperature) is equal to 45 mm, with the biggest changes during winter. In the growing season, the highest increases are expected to appear in July and June. As regards the spatial distribution, the highest increases are projected for the areas with presently highest evapotranspiration, e.g. the southwestern parts of the region.

    This paper examines the cost efficiency of dairy farms in 2 important regions of commercial milk production in Poland (i.e., Wielkopolskie and Podlaskie). Both regions gained importance following the market-driven resource allocation mechanism adopted after Poland's transition to the market economy in 1989 and accession to the European Union (EU) in 2004. The elimination of the dairy quota system in the EU in 2015 offers new expansion opportunities. The analysis of trends in cow numbers, milk production, and yield per cow shows different patterns of expansion of the dairy sector in the 2 regions. We selected dairy farm data from the Farm Accounts Data Network database for both regions and applied the cost frontier estimation model to calculate the relative cost-efficiency index for the period 2004 to 2009. The indexes compare each farm in the sample to the most efficient dairy farm in each region separately. Additionally, the top 5% of dairy farms with the highest relative cost efficiency index from each region were compared in terms of production costs with published results from a study using the representative farm approach. The comparison of results from 2 different studies permits a conclusion that Wielkopolskie and Podlaskie dairy farms are able to compete with farms from the 4 largest milk-producing countries in the EU. Although both regions can improve yields per cow, especially Podlaskie, both regions are likely to take advantage of the expansion opportunities offered by the 2015 termination of the milk quota system.

    In Poland in 2009 were reported 22 malaria cases confirmed according to the EU case definition for the purposes of routine surveillance system. All of them were imported, including 1 case of recrudescence, 86% from Africa. In 18 cases P falciparum etiology was confirmed and in 2--P vivax, in 1--P ovale and 1 P malariae. Most cases occurred in the age group 21-40 years, there were 21 cases in males and 1 in female. Common reasons for travel to endemic countries were work-related visits (14 cases) and tourism (6 cases), one person who visited the family and in one case unknown reason for travel. Three persons used chemoprophylaxis during their travel but only one of them appropriately, relevant information was missing in 5 cases. Clinical course was severe in 7 cases of P falciparum malaria and medium-severe in one case. In 2009, there were no malaria deaths in Poland. Education on the prevention of malaria and pretravel health advising is still greatly needed. PMID:21913479

    In Poland in 2007 there were 11 malaria cases confirmed according to the European Union cases definition reported through the routine surveillance system. All of them were imported, 82% from Africa, including 2 cases of relapse. Invasion with Plasmodium falciparum was diagnosed in 7 cases, mixed invasion in 2 cases and P. vivax- in one case. The majority of cases were in the age group 35-45 (8 cases) and were males (10 cases). Common reasons for travel to endemic countries were work-related (5 cases) and tourism or family visits (4 cases). Approximately half of the cases for whom the information was available used malaria chemoprophylaxis during their travel. Clinical course was severe in one case of P. falciparum malaria and the person died of the disease. The decreasing trend in malaria incidence in Poland is likely related to incomplete reporting as tourist and professional travel to endemic areas has not decreased and there is no indication of wider use ofchemoprophylaxis.

    Organic contaminant concentrations in mussels and oysters were compared between archived samples of a Mussel Watch Program of the 1970s and samples collected in the 1980s and the 1990s by the National Oceanic and Atmospheric Administration`s (NOAA`s) National Status and Trends Mussel Watch Project. These comparisons are possible because 51 sites of the current Mussel Watch Project were co-located with sites of the 1970s program. Archived samples were analyzed using current analytical techniques and were analyzed concurrently with the 1992 samples of NOAA`s Mussel Watch Project. Chlorinated pesticides and polycyclic aromatic hydrocarbons, displayed significant decreases between the 1970s and the 1990s. Polychlorinated biphenyls and butyltins were found in higher concentrations in the first year that they were quantified by NOAA`s Mussel Watch Project (1986 and 1989, respectively) than in the 1970s samples. Concentrations for both have decreased since then. The original 1970s analytical results were also compared to current analytical results from archived samples. Results were comparable for the quantification of DDE. Polycyclic aromatic hydrocarbon analyses were generally comparable for the greater than 3-ring molecules. When a conversion factor was applied, results were also comparable for the quantification of PCBs even though the early methods quantified Aroclor 1254 and the more recent method quantifies PCBs by congener.

    In the current work, we use the Constant Volume model and the numerical method, Regularized Smoothed Particle Hydrodynamics (RSPH) to study propagation and reflection of blast waves from detonations of the high explosives C-4 and TNT. The results from simulations of free-field TNT explosions are compared to previously published data, and good agreement is found. Measurements from height of burst tests performed by the Norwegian Defence Estates Agency are used to compare against numerical simulations. The results for shock time of arrival and the pressure levels are well represented by the numerical results. The results are also found to be in good agreement with results from a commercially available code. The effect of allowing different ratios of specific heat capacities in the explosive products are studied. We also evaluate the effect of changing the charge shape and height of burst on the triple point trajectory.

    Survey of recently published studies on globular clusters, and comparison of stellar evolution and pulsation theory with reported observations. The theory of stellar evolution is shown to be capable of describing, in principle, the behavior of a star through all quasi-static stages. Yet, as might be expected, estimates of bulk properties obtained by comparing observations with results of pulsation and stellar atmosphere theory differ somewhat from estimates of these same properties obtained by comparing observations with results of evolution theory. A description is given of how such estimates are obtained, and suggestions are offered as to where the weak points in each theory may lie.

    The Central Register of Occupational Diseases keeps the records of all reported and certified occupational diseases in Poland. In this paper the incidence of occupational diseases in Poland in 2001 is discussed on the basis of the data provided by the Register. The changes in the incidence pattern over the recent 30 years are also shown. In 2001, 6,007 cases of occupational diseases were registered, with the incidence rate of 63.2 per 100,000 employees. The highest incidence rates were noted for seven categories of diseases: the vocal organ diseases, noise-induced hearing loss, pneumoconioses, contagious and invasive diseases, dermatoses, chronic diseases of bronchi, and vibration syndrome. Altogether these diseases covered 5,239 cases (87.2% of all registered cases). Mining and quarrying, agriculture, hunting and forestry, education, health and social works were the economy activities with the highest incidence of occupational diseases. The majority of occupational diseases (93.9%) have developed after a long-term (over 10 years) exposure to particular harmful factors. As much as 58.5% of cases were recorded in males. The predominant occupational diseases in males were occupational hearing lesions, while in females chronic vocal organ diseases, most common in teachers, were most frequently recognized. In Poland, the diseases of the vocal organ poses a serious problem from the medical and socio-economic points of view. These pathologies show the highest dynamics of the incidence among all registered occupational diseases. Over the last five years the vocal organ diseases have moved upwards to the top in the ranking, both with respect to the number of cases and the incidence rate. Since 1998, the incidence of occupational diseases has been continuously showing a downward tendency. Four categories of occupational diseases have accounted mostly for this decline: noise-induced hearing loss, chronic diseases of vocal organ, contagious and invasive diseases, and

    Increasing environmental threats to agricultural production and the stability of ecosystems have been observed on the Polish lowlands since the 1970s. Several hundred million trees and shrubs have been planted on farmland, mostly along roads and with the involvement of public agencies, with a view to timber being produced, and soil erosion and the water deficit mitigated. On the basis of over 50 years of practical observations and scientific experiments, recommendations have been drawn up as regards the structural and spatial features of new tree planting outside forests that maximize environmental, production-related and social benefits. This paper gives a brief description of the history of the active establishment of woody vegetation across agricultural landscapes in Poland, along with best practices elaborated for this at several scientific centres.

    The epidemics of HIV infection spreads wider and wider. It is estimated that in 2002 about 5 million new cases were registered in the world. In the paper there were analysed information concerning cases of HIV infection and AIDS cases reported in Poland in the years 1985-2002. The epidemic situation of HIV infection and AIDS was compared with the data on the epidemics of the disease in other European countries given in the reports of the World Health Organisation. The number of newly diagnosed cases of HIV infection equaled 7880 in the studied period in Poland. Until the end of the year 2001 there were diagnosed 1153 cases of AIDS and 570 patients died of it. In comparison with other European countries the prevalence of HIV carrier state is low in the Polish population. The main group of HIV infection risk in our country are i.v. drug abusers, and among newly detected carriers the majority are men aged 20-29. Dynamic increase of HIV infected patients in the countries being neighbours of Poland that is Russia, Belarus and Ukraine as well as the rise in importance of the of heterosexual intercourses as a means of spreading of the virus may become a threat to health of the Polish population.

    2005-09-01

    The history and present status of the middle and long wavelength Hg1xCdxTe infrared detectors in Poland are reviewed. Research and development efforts in Poland were concentrated mostly on uncooled market niche. Technology of the infrared photodetectors has been developed by several research groups. The devices are based on mercury-based variable band gap semiconductor alloys. Modified isothermal vapor phase epitaxy (ISOVPE) has been used for many years for research and commercial fabrication of photoconductive, photoelectromagnetic and other devices. Bulk growth and liquid phase epitaxy was also used. At present, the fabrication of IR devices relies on low temperature epitaxial technique, namely metalorganic vapor phase deposition (MOCVD), frequently in combination with the ISOVPE. Photoconductive and photoelectromagnetic detectors are still in production. The devices are gradually replaced with photovoltaic devices which offer inherent advantages of no electric or magnetic bias, no heat load and no flicker noise. Potentially, the PV devices could offer high performance and very fast response. Actually, the uncooled long wavelength devices of conventional design suffer from two issues; namely low quantum efficiency and very low junction resistance. It makes them useless for practical applications. The problems have been solved with advanced 3D band gap engineered architecture, multiple cell heterojunction devices connected in series, monolithic integration of the detectors with microoptics and other improvements. Present fabrication program includes devices which are optimized for operation at any wavelength within a wide spectral range 1-15 μm and 200-300 K temperature range. Special solutions have been applied to improve speed of response. Some devices show picoseconds range response time. The devices have found numerous civilian and military applications.

    Retrieval of immature oocytes from unstimulated ovaries, followed by in vitro maturation (IVM) was originally proposed in order to avoid side effects of gonadotropin administration. The target is to eliminate or significantly reduce the risk of ovarian hyperstimulation syndrome (OHSS) in patients with polycystic ovary syndrome (PCOS), drug cost and burden on patients. This technology was also suggested in treatment of normo-ovulatory women, fertility preservation or infrequent conditions such as failure of oocytes to mature or repeated development of poor quality embryos. In this study we intended to examine the possibility that IVM results may be comparable to standard IVF. A PubMed database search from 1999-2013 was carried out for publications concerning the indications of IVM and study the possibility that IVM results may be comparable to standard IVF. In vitro maturation of the oocytes procedures obtained up to 35% clinical pregnancy rate in young women, comparable with in vitro fertilization (IVF) in many programs. The obstetric and perinatal outcomes of IVM cycles are comparable with IVF/ICSI cycles. In conclusion IVM may gradually replace IVF in certain cases, as the technique continues to develop and pregnancy rates continue to increase, being a promising and simple alternative approach to standard IVF in various indications.

    In the past, the entire field of science and technology in Poland was divided into three sectors: the Academy of Sciences, the universities and other academic institutions, and the research and development institutes. The level of collaboration among these sectors was low, and the system of financing science and technology was centralized, bureaucratic, and inefficient. The present Science Bill,' which came into force in January, 1991, has three important new features: autonomy, scientific merit, and openness. The coordination of government policy in this field has been entrusted to the KBN (State Committee for Scientific Research). Members of the Committee and its two commissions - one each for basic and applied research - are elected by the scientific community in direct two-stage elections. This new approach to the management of scientific research organization and financing should result in better utilization of budgetary resources allocated for science in Poland.

    A previous study used RELAP and RAVEN to conduct a boiling water reactor station black-out (SBO) case study in a simulation based environment to show the capabilities of the risk-informed safety margin characterization methodology. This report compares the RELAP/RAVEN simulation results with traditional PRA model results. The RELAP/RAVEN simulation run results were reviewed for their input parameters and output results. The input parameters for each simulation run include various timing information such as diesel generator or offsite power recovery time, Safety Relief Valve stuck open time, High Pressure Core Injection or Reactor Core Isolation Cooling fail to run time, extended core cooling operation time, depressurization delay time, and firewater injection time. The output results include the maximum fuel clad temperature, the outcome, and the simulation end time. A traditional SBO PRA model in this report contains four event trees that are linked together with the transferring feature in SAPHIRE software. Unlike the usual Level 1 PRA quantification process in which only core damage sequences are quantified, this report quantifies all SBO sequences, whether they are core damage sequences or success (i.e., non core damage) sequences, in order to provide a full comparison with the simulation results. Three different approaches were used to solve event tree top events and quantify the SBO sequences: “W” process flag, default process flag without proper adjustment, and default process flag with adjustment to account for the success branch probabilities. Without post-processing, the first two approaches yield incorrect results with a total conditional probability greater than 1.0. The last approach accounts for the success branch probabilities and provides correct conditional sequence probabilities that are to be used for comparison. To better compare the results from the PRA model and the simulation runs, a simplified SBO event tree was developed with only four

    Background: Measuring quality of care and ranking hospitals with outcome measures poses two major methodological challenges: case-mix adjustment and variation that exists by chance. Aim: To compare methods for comparing and ranking hospitals that considers these. Methods: The Netherlands Stroke Survey was conducted in 10 hospitals in the Netherlands, between October 2002 and May 2003, with prospective and consecutive enrolment of patients with acute brain ischaemia. Poor outcome was defined as death or disability after 1 year (modified Rankin scale of ⩾3). We calculated fixed and random hospital effects on poor outcome, unadjusted and adjusted for patient characteristics. We compared the hospitals using the expected rank, a novel statistical measure incorporating the magnitude and the uncertainty of differences in outcome. Results: At 1 year after stroke, 268 of the total 505 patients (53%) had a poor outcome. There were substantial differences in outcome between hospitals in unadjusted analysis (χ2 = 48, 9 df, P < 0.0001). Adjustment for 12 confounders led to halving of the χ2 (χ2 = 24). The same pattern was observed in random effects analysis. Estimated performance of individual hospitals changed considerably between unadjusted and adjusted analysis. Further changes were seen with random effect estimation, especially for smaller hospitals. Ordering by expected rank led to shrinkage of the original ranks of 1–10 towards the median rank of 5.5 and to a different order of the hospitals, compared to ranking based on fixed effects. Conclusion: In comparing and ranking hospitals, case-mix-adjusted random effect estimates and the expected ranks are more robust alternatives to traditional fixed effect estimates and simple rankings.

    The compressional velocities are estimated for materials thought to be important in the lunar interior and compared with lunar seismic results. The lower lunar crust has velocities appropriate for basalts or anorthosites. Anorthosite is preferred if lunar basalts result from a small degree of partial melting. The high velocities associated with the uppermost mantle imply high densities and a change to a lighter assemblage at depths of the order of 120 km. Ca- and Al-rich minerals are important components of both the lower crust and the upper mantle. Most of the moon may have accreted from refractory material rich in Ca, Al, U, and the rare-earth elements. The important mineral of the upper mantle is garnet; possible accessory minerals are kyanite, spinel and rutile. If the seismic results stand up, the high-velocity layer in the moon is more likely to be a high-pressure form of anorthosite than eclogite, pyroxenite, or dunite.

  7. Emigration preferences and plans among medical students in Poland

    Background Migration and ethical recruitment of health care workers is receiving increased attention worldwide. Europe’s aging population is creating new opportunities for medical doctors for finding employment in other countries, particularly those of a better standard of living. Methods We conducted a survey among 1214 medical students in five out of eleven universities in Poland with medical schools in October 2008. A series of statistical tests was applied to analyse the characteristics of potential migrants. Projections were obtained using statistical analyses: descriptive, multifactorial logistic regression and other statistical methods . Results We can forecast that 26–36% of Polish medical students will emigrate over the next few years; 62% of respondents estimated the likelihood of emigration at 50%. Students in their penultimate year of study declared a stronger desire to migrate than those in the final year. At the same time, many students were optimistic about career opportunities in Poland. Also noted among students were: the decline in interest in leaving among final year students, their moderate elaboration of departure plans, and their generally optimistic views about the opportunities for professional development in Poland. Conclusions The majority of Polish students see the emigration as a serious alternative to the continuation of their professional training. This trend can pose a serious threat to the Polish health care system, however the observed decline of the interest in leaving among final year students, the moderate involvement in concrete departure plans and the optimistic views about the opportunities for professional development in Poland suggest that the actual scale of brain drain of young Polish doctors due to emigration will be more limited than previously feared.

    Radiation transmission, leakage and beam penumbra are essential dosimetric parameters related to the commissioning of a multileaf collimation system. This work shows a comparative analysis of commonly used film detectors: X-OMAT V2 and EDR2 radiographic films, and GafChromic EBT registered radiochromic film. The results show that X-OMAT over-estimates radiation leakage and 80-20% beam penumbra. However, according to the reference values reported by the manufacturer for these dosimetric parameters, all three films are adequate for MLC dosimetric characterization, but special care must be taken when X-OMAT V2 film is used due to its low energy photon dependence.

    The results of a functional analysis of problem behavior and a paired-choice assessment were compared to determine whether the same social reinforcers were identified for problem behavior and an appropriate response (time allocation). The two assessments were conducted in classroom settings with 4 adolescents with mental retardation who engaged in severe problem behavior. Each student's classroom teacher served as the therapist for all phases of assessment. The two assessment procedures identified the same social reinforcers for problem and appropriate behavior for 3 of 4 participants. PMID:17970268

    We analyze the scaling laws for a set of two different species of long flexible polymer chains joined together at one of their extremities (copolymer stars) in space dimension D=2. We use a formerly constructed field-theoretic description and compare our perturbative results for the scaling exponents with recent conjectures for exact conformal scaling dimensions derived by a conformal invariance technique in the context of D=2 quantum gravity. A simple Monte Carlo simulation brings about reasonable agreement with both approaches. We analyze the remarkable multifractal properties of the spectrum of scaling exponents. PMID:12005898

    Background The surgical treatment of advanced megaesophagus has no consensus, being esophagectomy the more commonly used method. Since it has high morbimortality - inconvenient for benign disease -, in recent years an alternative has been introduced: the esophageal mucosal resection. Aim To compare early and late results of the two techniques evaluating the operative time, length of ICU stay; postoperative hospitalization; total hospitalization; intra- and postoperative complication rates; mortality; and long-term results. Methods Were evaluated retrospectively 40 charts, 23 esophagectomies and 17 mucosectomies. In assessing postoperative results, interviews were conducted by using a specific questionnaire. Results Comparing the means of esophagectomy and mucosal resection, respectively, the data were: 1) surgical time - 310.2 min and 279.7 min (p> 0.05); 2) length of stay in ICU - 5 days and 2.53 days (p <0.05); 3) total time of hospitalization - 24.25 days and 20.76 days (p> 0.05); 4) length of hospital stay after surgery - 19.05 days and 14.94 days (p> 0.05); 5) presence of intraoperative complications - 65% and 18% (p <0.05); 6) the presence of postoperative complications - 65% and 35% (p> 0.05). In the assessment of late postoperative score (range 0-10) esophagectomy (n = 5) obtained 8.8 points and 8.8 points also got mucosal resection (n = 5). Conclusions Esophageal mucosal resection proved to be good alternative for surgical treatment of megaesophagus. It was advantageous in the immediate postoperative period by presenting a lower average time in operation, the total hospitalization, ICU staying and complications rate. In the late postoperative period, the result was excellent and good in both operations. PMID:25861065

    OBJECT The object of this study was to compare the clinical, functional, and aesthetic results of 2 surgical techniques, pterional (PT) and minipterional (MPT) craniotomies, for microsurgical clipping of anterior circulation aneurysms. METHODS Fifty-eight patients with ruptured and unruptured anterior circulation aneurysms were enrolled into a prospective randomized study. The first group included 28 patients who underwent the MPT technique, and the second group comprised 30 patients who underwent the classic PT craniotomy. To evaluate the aesthetic effects, patients were asked to grade on a rule from 0 to 100 the best and the worst aesthetic result. Photographs were also taken, assessed by 2 independent observers, and classified as showing excellent, good, regular, or poor aesthetic results. Furthermore, quantitative radiological assessment (percentage reduction in thickness and volumetric analysis) of the temporal muscle, subcutaneous tissue, and skin was performed. Functional outcomes were compared using the modified Rankin Scale (mRS). Frontal facial palsy, postoperative hemorrhage, cerebrospinal fistula, hydrocephalus, and mortality were also analyzed. RESULTS Demographic and preoperative characteristics were similar in both groups. Satisfaction in terms of aesthetic result was observed in 19 patients (79%) in the MPT group and 13 (52%) in the PT group (p = 0.07). The mean score on the aesthetic rule was 27 in the MPT group and 45.8 in the PT group (p = 0.03). Two independent observers analyzed the patient photos, and the kappa coefficient for the aesthetic results was 0.73. According to these observers, excellent and good results were seen in 21 patients (87%) in the MPT and 12 (48%) in the PT groups. The degree of temporal muscle, subcutaneous tissue, and skin atrophy was 14.9% in the MPT group and 24.3% in the PT group (p = 0.01). Measurements of the temporal muscle revealed 12.7% atrophy in the MPT group and 22% atrophy in the PT group (p = 0.005). The

    Background Conventional stripping is considered to be the standard procedure for great saphenous vein (GSV) varicosities, but many other alternative treatments such as cryostripping, endovenous laser therapy (EVLT), radio-frequency ablation, and ultrasound-guided foam sclerotherapy have been developed. Among them, both cryostripping and laser therapy have been reported to be less traumatic, with lower rates of complications and recurrences when compared to conventional stripping. To compare the efficacy of these treatments, we have analyzed and compared the mid-term clinical outcomes of cryostripping and EVLT. Methods Patients diagnosed with varicose veins of the GSV and treated with cryostripping or laser therapy between September 2008 and April 2013 were enrolled in this study. Duplex ultrasonography was used for the diagnosis and evaluation of varicosity and reflux, and the clinical-etiology-anatomy-pathophysiology classification was used to measure the clinical severity. The symptoms, Venous Clinical Severity Score (VCSS), recurrence rates, and complication rates of the cryostripping and laser therapy groups were analyzed and compared. Results A total of 68 patients were enrolled in this study. 32 patients were treated with cryostripping, and 36 patients were treated with laser therapy. The median follow-up period was 29.6 months. Recurrence was noted in three patients from the cryostripping group and in two patients from the EVLT group. There was no difference in the VCSS score, operative time, duration of hospital stay, and complication rate between the cryostripping group and the EVLT group. Conclusion The mid-term clinical outcomes of cryostripping were not inferior to those of EVLT. Further, considering its cost-effectiveness, cryostripping seems to be a safe and feasible method for the treatment of varicose veins. PMID:26509128

    In 1979 the Cancer Control Agency of British Columbia changed from radium to remote controlled afterloaded caesium in the treatment of carcinoma of the cervix. In the 3 years prior to the change, 139 patients received radium as part of their treatment and in the 3 years after the change, 158 patients received caesium. Overall referral patterns, patient and cancer demographics, and treatment policies were stable throughout the 6-year period. Radiotherapy technique, dose, dose distribution and dose rate were comparable for both radium and caesium treated patients. The results of treatment in the two time periods showed no difference in survival, local tumour control or complications. The use of afterloading has not compromised treatment results and has allowed better nursing care for patients and protection from radiation for all staff. PMID:2752690

    The aim by our group is to understand the behaviour of the grouping methyl starting from the study of molecules having a great symmetry. In this part of work, it is had the crystalline structure of the dinitromesitylen (DNM) who is solved starting from the diffraction of x-rays starting from a monocrystal at the ambient temperature. Parallel to the experimental study, we undertook theoretical calculations conformation of the insulated molecule of DNM by using the methods of the DFT (Density Functional Theory).Calculations of optimization of the molecular conformation of the DNM by using the chain of program GAUSSIAN03 and functional MPW1PW91, B3LYP level with the 6-311G and LANL2DZ bases gave a conformation Cs with results very close to the experiment for the lengths and the angles of bond. The computation results obtained starting from the base set (6-311G) and functional MPW1PW91 give for the conformation of Dinitromesitylen (DNM) a good agreement of about a 1.9% for the lengths of bond and 1.2% for the angles of bond compared with the results of the diffraction of x-rays. Calculations of Raman and infra-red spectroscopy undertaken starting from the results of optimization by using same functional MPW1PW91 and B3LYP and the sets of bases 6-311G LanL2DZ led to the values of frequencies very close to the experimental results.

    The comparison of the clinical results and costs of the two methods of closure of patient ductus arteriosus was undertaken in two comparable groups of 40 patients treated in the same period in the same hospital. After transcatheter closure there was a 9% residual shunt rate at 3 years, the 2 patients with a residual continuous murmur being operated secondarily. The only complication was severe haemolysis which regressed after transcatheter ablation of the prosthesis. After surgical closure, there were no residual shunt. Some postoperative complications were observed in 20% of cases, usually benign (ventilatory problems, dysphonia or urinary infection), but occasionally more serious (peroperative lesion of the pulmonary artery). Morbidity, inherent to the technique of closure, was very different and much less in catheter closure. The average cost (daily cost x average length of hospital stay) was much less with transcatheter closure 38,558 francs versus 11,240 francs. On the other hand, the direct cost of transcatheter closure was greater than that of surgery: 32,798 francs versus 20,903 francs, the difference being related to the actual price of the prosthesis. The authors conclude that the 3 year results of transcatheter closure of patent ductus arterious make this technique a reasonable therapeutic alternative to surgery. From the safety point of view, the two techniques are comparable bu patient confort is greater with transcatheter closure for an increase in cost of the initial procedure which should decrease in relation to the types and prices of the prosthesis used.

    We compare and interpret results of several rock fabric analysis techniques, as applied to samples of plagioclase-hornblende porphyry from a well-exposed small intrusion in the Henry Mountains of southern Utah, U.S.A. The fabric analysis techniques considered include field measurements of phenocryst shape-preferred orientation, anisotropy of magnetic susceptibility, anisotropy of anhysteric remanent magnetization, high- resolution X-ray computed tomography, and three-dimensional shape-preferred orientation calculated from two- dimensional image analysis. The exceptional exposure of the studied intrusion allows us to confidently infer magma flow kinematics and to estimate the minimum amount of shear strain accommodated by the magma during emplacement. Our study therefore provides an important contrast to most studies, in which flow kinematics and magmatic strain are inferred from rock fabric in incompletely exposed intrusions. We find that observed fabric orientations often closely mimic local intrusion geometry, making it difficult to infer general magmatic flow kinematics from fabric near contacts. At each analysis location, orientation results from each technique generally agree but fabric shape and magnitude parameters vary widely between techniques. Fabric shape may therefore not provide useful information about flow kinematics (e.g. constrictional vs. flattening flow). Similarly, fabric magnitudes plateau at moderate values and do not provide a useful strain gauge. Because each technique provides unique information, it is invariably beneficial to use more than one fabric analysis technique. Failure to check results from one technique against those from another can results in misinterpretation of intrusion flow kinematics.

Consistent with a hypothesis derived from national differences in relative levels of collectivism and individualism, both direct and indirect aggression were higher in the US than in Poland and higher in Poland than in China. The theoretical implication of these results and directions for future research were discussed. PMID:18985769

    This paper examines the shape of the recently reformed health care system in Poland. Until December 31,1998 everyone had access to free health care and the medical institutions were financed by the State. Since January 1, 1999, under the provisions of the Universal Health Insurance Act, hospitals became independent from the State budget and gained more financial resources for their activities. 17 regional health insurance funds contract for medical services with hospitals and individual practices. Most services provided to the insured are paid by the funds that receive premiums, but some are still financed from the State budget. The revised legislation on Medical Care Establishments intended to create a better management of health care institutions and administrative control over the quality of care. The system has been severely criticised: it is too bureaucratic, there are too many insurance funds, patients have experienced problems with access to health care, particularly to special treatment or to treatment available outside the area of the health insurance fund to which the patient belongs. The new Minister for Health suggested that the 17 funds should be replaced by 5 "health funds" that would finance health care and be closely connected to the local government answerable for their activities. This paper will deal with the scope of health care packages, the conditions of provision of health services, obligations of health care providers, patient rights, and the quality of health care.

    The paper is aimed at presenting the incidence of occupational diseases in Poland. The analysis was performed on the basis of the information included in 'occupational disease certificates'. All sanitary and epidemiological stations throughout the country are committed to send these certificates to the Central Register of Occupational Medicine in The Nofer Institute of Occupational Medicine in Lódź. The incidence of occupational diseases during the three recent years (1996-97-98) was the subject of a thorough analysis. In all, 11,318, 11,685 and 12,017 cases of occupational diseases, respectively were registered over those three years. The corresponding rates were 116.0, 116.9 and 117.3, respectively per 100,000 people employed. In 1998, diseases of the voice organ predominated (30.4%) of all occupational diseases) and they were followed by hearing impairment (28.2%), infectious and parasitic diseases (9.9%), pneumoconioses (8.2%), dermatoses (6.4%), vibratory syndrome (2.9%) and poisoning (2.5%). These disease categories constituted over 88% of all occupational diseases registered in that year. Diseases of the voice organ which showed the greatest growth dynamic were mainly diagnosed among teachers. Neither in the United States nor in the member states of the European Union, this pathology is included into the list of occupational diseases. In view of high rates of its incidence in our country it has become one of essential problems of occupational medicine. In Poland, particular attention is paid to infectious and parasitic diseases among which hepatitis occupies the first place (65%), mostly among health service workers. The decrease in hepatitis incidence observed in the 1990s has been due to an intensive vaccination programme in this group of workers. The incidence of occupational hepatitis became rather stable and accounted for 940 cases per year, however the incidence of hepatitic C increased at the same time.

    Background Candidate gene studies have been a key approach to the genetics of schizophrenia. Results of these studies have been confusing and no genes have been unequivocally implicated. The hypothesis-driven candidate gene literature can be appraised via comparison with the results of genome-wide association studies (GWAS). Methods We described the characteristics of hypothesis-driven candidate gene studies from SZGene, and used pathway analysis to compare hypothesis-driven candidate genes with GWAS results from the International Schizophrenia Consortium (ISC). Results SZGene contained 732 autosomal genes evaluated in 1,374 studies. These genes had poor statistical power to detect genetic effects typical for human diseases, assessed only 3.7% of genes in the genome, and had low marker densities per gene. Most genes were assessed once or twice (76.9%), providing minimal ability to evaluate consensus across studies. The ISC had power of 89% to detect a genetic effect typical for common human diseases and assessed 79% of known autosomal common genetic variation. Pathway analyses did not reveal enrichment of smaller ISC p-values in hypothesis-driven candidate genes nor did a comprehensive evaluation of meta-hypotheses driving candidate gene selection (schizophrenia as a disease of the synapse or neurodevelopment). The most studied hypothesis-driven candidate genes had no notable ISC results (COMT, DRD3, DRD2, HTR2A, NRG1, BDNF, DTNBP1, and SLC6A4). Conclusions We did not find support for the idea that the hypothesis-driven candidate genes studied in the literature were enriched for common variation involved in the etiology of schizophrenia. Larger samples are required definitively to evaluate this conclusion. PMID:21854684

    Seventy-one patients with neuroblastoma (NB) and 25 patients with other neoplastic or nonneoplastic diseases were studied with MIBG scintigraphy. Sensitivity and specificity at diagnosis were 94% and 88%, respectively. Of 52 patients with NB studied during follow-up, 14 had on one or several occasions conflicting results, when the findings at MIBG scintigraphy were compared to standard investigations (SI: CT scan, bone scan, x-ray, and ultrasound). The correlation of MIBG scintigraphy and SI to clinical outcome were in these 14 patients not significantly different. Adding VMA-excretion measurements did not significantly improve the predictive value of MIBG scintigraphy or SI. Patients with tumor-suspected lesions only at MIBG scintigraphy should be followed closely and the nature of the lesions should be explored through biopsy.

    We compare the results of the photometrical analysis of barred galaxies with those of a similar analysis from N-body simulations. The photometry is for a sample of nine barred galaxies observed in the J and K[s] bands with the CANICA near infrared (NIR) camera at the 2.1 m telescope of the Observatorio Astrofísico Guillermo Haro (OAGH) in Cananea, Sonora, Mexico. The comparison includes radial ellipticity profiles and surface brightness (density for the N-body galaxies) profiles along the bar major and minor axes. We find very good agreement, arguing that the exchange of angular momentum within the galaxy plays a determinant role in the evolution of barred galaxies.

    The article presents the results of the first study on seasonal activity of ticks and prevalence of tick-borne encephalitis virus (TBEV) in nymphs from the Silesian Province (Southern Poland). Previous studies on the prevalence of TBEV in ticks in Poland have been conducted mostly in northern and eastern regions, but none in the Silesian Province itself. The aims of this study were to analyse the seasonal variation in tick populations and compare TBEV prevalence in nymphs from different geographical locations in the Silesia. A total of 5160 questing Ixodes ricinus ticks were collected by the flagging method from 23 localities in southern Poland in 2010. Micro-climatic parameters (air temperature and humidity) were measured in order to estimate their influence on tick population. The highest tick activity was recorded in spring and was positively correlated with relative air humidity (RH). TBEV in the Silesian Province was analysed in 1750 nymphs and an overall prevalence was 0.11% (2 pools out of 175 analysed). The results of this study show that TBEV pool prevalence in nymphs is low in accordance with the low number of TBE cases reported within the region. PMID:25838177

    Introduction. Delta Healthy Sprouts trial was designed to test the comparative impact of two home visiting programs on weight status, dietary intake, and health behaviors of Southern African American women and their infants. Results pertaining to the primary outcome, gestational weight gain, are reported. Methods. Participants (n = 82), enrolled early in their second trimester of pregnancy, were randomly assigned to one of two treatment arms. Gestational weight gain, measured at six monthly home visits, was calculated by subtracting measured weight at each visit from self-reported prepregnancy weight. Weight gain was classified as under, within, or exceeding the Institute of Medicine recommendations based on prepregnancy body mass index. Chi-square tests and generalized linear mixed models were used to test for significant differences in percentages of participants within recommended weight gain ranges. Results. Differences in percentages of participants within the gestational weight gain guidelines were not significant between treatment arms across all visits. Conclusions. Enhancing the gestational nutrition and physical activity components of an existing home visiting program is feasible in a high risk population of primarily low income African American women. The impact of these enhancements on appropriate gestational weight gain is questionable given the more basic living needs of such women. This trial is registered with ClinicalTrials.gov NCT01746394, registered 4 December 2012. PMID:27595023

    The main source of acrylamide in the diet are thermally processed carbohydrate-rich products, mainly those obtained from potatoes. Acrylamide is a substance with neurotoxic, genotoxic and carcinogenic properties. The International Agency for Research on Cancer classified it as a potential human carcinogen in 1994. The purpose of this study was to assess acrylamide content in 24 samples of crisps randomly collected in Poland in 2004. Acrylamide was determined in the form of brominated derivatives by gas chromatography coupled with mass spectrometry. The average acrylamide content in the crisp samples examined was 998 mg/kg of the product, ranging from 352 to 3647 microg/kg, depending on the type of the crisps. The factor determining the differences in acrylamide content in the product was also the manufacturer. The average content of acrylamide in the crisps produced by three different manufacturers (manufacturers 1-3) was ca. 600-900 microg/kg, and in the crisps produced by manufacturer 4 was ca. 3 times higher. Moreover, substantial differences were found between the same types of crisps produced by the same manufacturers but originating from different manufacturing batches. The results obtained suggest the effects of various technological processes and raw material types on the level of acrylamide in crisps. PMID:17193744

In this study, we used the official 1998-2003 inventory data on ungulate numbers from 462 forest districts and 23 national parks across Poland to determine the roles of various environmental factors in shaping country-wide spatial patterns of ungulate abundances. Spatially explicit generalized additive mixed models showed that different sets of environmental variables explained 39 to 50 % of the variation in red deer Cervus elaphus, wild boar Sus scrofa, and roe deer Capreolus capreolus abundances. For all of the studied species, low forest cover and the mean January temperature were the most important factors limiting their numbers. Woodland cover above 40-50 % held the highest densities for these species. Wild boar and roe deer were more numerous in deciduous or mixed woodlands within a matrix of arable land. Furthermore, we found significant positive effects of marshes and water bodies on wild boar abundances. A juxtaposition of obtained results with ongoing environmental changes (global warming, increase in forest cover) may indicate future growth in ungulate distributions and numbers. PMID:24244044

    Johnson, A. Ivan

    On June 4, 1991, AGU Fellow Joseph Fairfield Poland died in a Sacramento, Calif., hospital at the age of 83 after a long fight with Parkinson's Disease. A recognized expert on land subsidence and a retiree from the U.S. Geological Survey's Water Resources Division, his death occurred only 2 weeks after the end of the 4th International Symposium on Land Subsidence, held in Houston, Tex. Frequently known as “Mr. Land Subsidence,” it was appropriate that the proceedings of that symposium had been dedicated to him.Born in Boston, Poland earned a bachelor's degree in geology from Harvard University in 1929. He was resident geologist for Tropical Oil Company in Colombia from 1929 to 1931. After returning to the United States, Poland earned his master's degree in geology from Stanford University in 1935, taught groundwater hydrology, and consulted on groundwater and geophysical problems in the West and Southwest.

    Friction laws are typically introduced either based on theoretic ideas or by fitting laboratory experiments that reproduce only a small subset of possible behaviors. Hence it is important to validate the resulting laws by modeling experiments that produce spontaneous frictional behavior. Here we simulate experiments of spontaneous rupture transition from sub-Rayleigh to supershear done by Xia et al. (Science, 2004). In the experiments, two thin Homalite plates are pressed together along an inclined interface. Compressive load P is applied to the edges of the plates and the rupture is triggered by an explosion of a small wire. Xia et al. (2004) link the transition in their experiments to the Burridge-Andrews mechanism (Andrews, JGR, 1976) which involves initiation of a daughter crack in front of the main rupture. Xia et al. have measured transition lengths for different values of the load P and compared their results with numerical simulations of Andrews who used linear slip-weakening friction. They conclude that to obtain a good fit they need to assume that the critical slip of the slip-weakening law scales as P-1/2, as proposed by Ohnaka (JGR, 2003). Hence our first goal is to verify whether the dependence of the critical slip on the compressive load P is indeed necessary for a good fit to experimental measurements. To test that, we conducted simulations of the experiments by using boundary integral methodology in its spectral formulation (Perrin et al., 1995; Geubelle and Rice, 1995). We approximately model the wire explosion by temporary normal stress decrease in the region of the interface comparable to the size of the exploding wire. The simulations show good agreement of the transition length with the experimental results for different values of the load P, even though we keep the critical slip constant. Hence the dependence of the critical slip on P is not necessary to fit the experimental measurements. The inconsistency between Andrews' numerical results

    Possible future climate change effects on dryness conditions in Poland are estimated for six climate projections using the standardized precipitation index (SPI). The time series of precipitation represent six different climate model runs under the selected emission scenario for the period 1971-2099. Monthly precipitation values were used to estimate the SPI for multiple timescales (1, 3, 6, 12, and 24 months) for a spatial resolution of 25 km for the whole country. Trends in the SPI were analysed using the Mann-Kendall test with Sen's slope estimator for each grid cell for each climate model projection and aggregation scale, and results obtained for uncorrected precipitation and bias corrected precipitation were compared. Bias correction was achieved using a distribution-based quantile mapping (QM) method in which the climate model precipitation series were adjusted relative to gridded precipitation data for Poland. The results show that the spatial pattern of the trend depends on the climate model, the timescale considered and on the bias correction. The effect of change on the projected trend due to bias correction is small compared to the variability among climate models. We also summarize the mechanisms underlying the influence of bias correction on trends in precipitation and the SPI using a simple example of a linear bias correction procedure. In both cases, the bias correction by QM does not change the direction of changes but can change the slope of trend, and the influence of bias correction on SPI is much reduced. We also have noticed that the results for the same global climate model, driving different regional climate model, are characterized by a similar pattern of changes, although this behaviour is not seen at all timescales and seasons.

    Possible future climate change effects on drought severity in Poland are estimated for six ENSEMBLE climate projections using the Standard Precipitation Index (SPI). The time series of precipitation represent six different RCM/GCM run under the A1B SRES scenario for the period 1971-2099. Monthly precipitation values were used to estimate the Standard Precipitation Index (SPI) for multiple time scales (1, 3, 6, 12 and 24 months) for a spatial resolution of 25 km × 25 km for the whole country. Trends in SPI were analysed using a Mann-Kendall test with Sen's slope estimator for each 25 km × 25 km grid cell for each RCM/GCM projection and timescale, and results obtained for uncorrected precipitation and bias corrected precipitation were compared. Bias correction was achieved using a distribution-based quantile mapping (QM) method in which the climate model precipitation series were adjusted relative to gridded E-OBS precipitation data for Poland. The results show that the spatial pattern of the trend depends on the climate model, the time scale considered and on the bias correction. The effect of change on the projected trend due to bias correction is small compared to the variability among climate models. We also summarise the mechanisms underlying the influence of bias correction on trends using a simple example of a linear bias correction procedure. In the case of precipitation the bias correction by QM does not change the direction of changes but can change the slope of trend. We also have noticed that the results for the same GCM, with differing RCMs, are characterized by similar pattern of changes, although this behaviour is not seen at all time scales and seasons.

    The aim of the study was to determine the rate of transmission of drug resistant human immunodeficiency virus-1 (HIV-1) variants among therapy-naïve HIV positive patients in Poland in the year 2008, to compare the data with the results from the years 2000 to 2007 and to monitor patterns of HIV-1 subtypes present in Polish population and their evolution. Complete protease and part of reverse transcriptase regions were sequenced from the sera of patients directed to the laboratory for drug resistance testing. The Stanford's HIVdb program was used for the interpretation of results and subtyping. The variants scoring at least "intermediate resistance" for at least one drug were considered as resistant. The results obtained were compared to those obtained in the years 2000-2007. A total of 95 patients were enrolled in the 2008 study. Homosexual transmission of infection was documented in more than 55% of all cases. The overall prevalence of transmitted drug resistance (TDR) was 5.3% (3.9% in 2007, 5.8% in 2006, and 14.1% in the years 2002-2005). The study from the years 2000 to 2001 revealed 28.7% prevalence. Preliminary analysis of the first half of 2009 shows the ratio of 7.8%. In four (4.2%) cases drug resistance was associated with protease inhibitors class, in one case (1.1%) with resistance to non-nucleoside reverse transcriptase inhibitors class. In four cases (4.2%) non-B subtype was identified (C, G, CRF01_AE, CRF02_AG). An increase of percentage of drug resistant mutants-from 3.9% (2007) to 5.3% (2008)-was recognized. In this study, TDR was limited to single classes of antiretroviral drugs. HIV-1 subtype B prevails in Poland. PMID:20513098

    Background: Developmental dysplasia of hip (DDH) is one of the congenital anomalies in newborns that if not diagnosed and treated on time can lead to a severe disability. Although clinical examination is a very useful way for screening, but in some patients, a confirmatory diagnostic method such as ultrasonography is needed. The aim of the present study is to compare the sensitivity and specificity of clinical examination and ultrasonography in early detecting of DDH. Materials and Methods: A total of 5800 of newborns were examined by orthopedic surgeon as a screening method. The newborns with risk factors or suspicious on clinical examination were introduced to repeat clinical and ultrasonographic examination of hip. The results were collected and recorded by a check list and then the sensitivity and specificity of clinical examination were calculated. Results: Of 5701 newborns (11402 hips) who were studied by two methods of clinical examination and ultrasonography (by Graf method), the overall incidence of DDH was 29 per 1000. Only 94 hips (13.5%) of 694 disordered ones according to clinical examination were involved on ultrasonographic evaluation. A total of 240 hips of 334 (72%) involved hips according to ultrasonography (Graf type IIb or more) were diagnosed normal on clinical examination, considering ultrasonography as a gold standard method of evaluating DDH, the sensitivity and specificity of clinical examination were calculated 28.1% and 94.5%, respectively. Conclusion: According to the present study, ultrasonogeraphic examination has a high valuable in screening of DDH and the clinical examination done by an experienced orthopedic surgeon has an acceptable value in primary screening of DDH in developing countries for detecting of healthy neonates, but if the newborn has a risk factor or is suspicious on clinical examination, it will be necessary to get assistance from ultrasonography by an experienced sonographer.

    In 1996 a program was started, financed by the Environmental Ministry of Portugal and IAEA, aiming to study the inorganic atmospheric pollutant dispersion in Sado Estuary. Gent PM10 air samplers were used for air particulate matter sampling. Three sampling sites were chosen, forming a triangle around the fuel power station of Setúbal. Transplants of Parmelia sulcata Taylor were suspended in nylon bags within a rectangle 15 km wide and 25 km long on a 2.5 x 2.5 km grid. Two sets of four transplants were hung in each of the 47 locations, one set facing the wind and the other set opposing the wind. The transplants were suspended in December 1997 for a 1-year period; every 3 months, one transplant of each set was collected. Both lichen transplants and PM10 filters were analysed by INAA and PIXE. A comparative study of results obtained for the two sampling procedures is presented in this work. PMID:12199472

    High speed machining (HSM), or high performance machining, has been one of the most recent technological advances. When applied to milling operations, using adequate machines, CAM programs and tooling, it allows cutting hardened steels, which was not feasible just a couple of years ago. The use of very stiff and precision machines has created the possibilities of machining holes in hardened steels, such as AISI H13 with 48-50 HRC, using helical interpolations, for example. Such process is particularly useful for holes with diameter bigger than normal solid carbide drills commercially available, around 20 mm, or higher. Such holes may need narrow tolerances, fine surface finishing, which can be obtained just by end milling operations. The present work compares some of the strategies used to obtain such holes by end milling, and also some techniques employed to finish them, by milling, boring and also by fine grinding at the same machine. Results indicate that it is possible to obtain holes with less than 0.36 m in circularity, 7.41 m in cylindricity and 0.12 m in surface roughness Ra. Additionally, there is less possibilities of obtaining heat affected layers when using such technique.

    Sixteen healthy exercise trained participants underwent the following three, 10-h exposures in a randomized manner: (1) Hypobaric hypoxia (HH; 3450m terrestrial altitude) (2) Normobaric hypoxia (NH; 3450m simulated altitude) and (3) Normobaric normoxia (NN). Plasma oxidative stress (malondialdehyde, MDA; advanced oxidation protein products, AOPP) and antioxidant markers (superoxide dismutase, SOD; glutathione peroxidase, GPX; catalase; ferric reducing antioxidant power, FRAP) were measured before and after each exposure. MDA was significantly higher after HH compared to NN condition (+24%). SOD and GPX activities were increased (vs. before; +29% and +54%) while FRAP was decreased (vs. before; -34%) only after 10h of HH. AOPP significantly increased after 10h for NH (vs. before; +83%), and HH (vs. before; +99%) whereas it remained stable in NN. These results provide evidence that prooxidant/antioxidant balance was impaired to a greater degree following acute exposure to terrestrial (HH) vs. simulated altitude (NH) and that the chamber confinement (NN) did likely not explain these differences.

  1. Comparing gender awareness in Dutch and Swedish first-year medical students - results from a questionaire

    PubMed Central

    2012-01-01

    Background To ascertain good and appropriate healthcare for both women and men implementation of gender perspectives in medical education is needed. For a successful implementation, knowledge about students' attitudes and beliefs about men, women, and gender is crucial. The aim of this study was to compare attitudes to gender and gender stereotyping among Dutch and Swedish male and female medical students. Methods In this cross-sectional study, we measured the attitudes and assumptions about gender among 1096 first year medical students (616 Dutch and 480 Swedish) with the validated Nijmegen Gender Awareness in Medicine Scale (N-GAMS). The response rate was 94% in the Netherlands and 93% in Sweden. Univariate analysis of variance (ANOVA) was used to compare the scores between Dutch and Swedish male and female students. Linear regressions were used to analyze the importance of the background variables. Results There were significant differences in attitudes to gender between Dutch and Swedish students. The Swedish students expressed less stereotypical thinking about patients and doctors and the Dutch were more sensitive to gender differences. The students' sex mattered for gender stereotyping, with male students in both countries agreeing more with stereotypical statements. Students' age, father's birth country and mother's education level had some impact on the outcome. Conclusions There are differences between cultures as well as between men and women in gender awareness that need to be considered when implementing gender in medical education. This study suggests that to arouse the students' interest in gender issues and make them aware of the significance of gender in medical work, the examples used in discussions need to be relevant and challenging in the context of the specific country. Due to different levels of knowledge and different attitudes within the student population it is important to create a climate for dialogue where students feel permitted to

    Background: This work demonstrates the importance of spatiotemporal stochastic modelling in constructing maps of major epidemics from fragmentary information, assessing population impacts, searching for possible etiologies, and performing comparative analysis of epidemics. Methods: Based on the theory previously published by the authors and incorporating new knowledge bases, informative maps of the composite space-time distributions were generated for important characteristics of two major epidemics: Black Death (14th century Western Europe) and bubonic plague (19th-20th century Indian subcontinent). Results: The comparative spatiotemporal analysis of the epidemics led to a number of interesting findings: (1) the two epidemics exhibited certain differences in their spatiotemporal characteristics (correlation structures, trends, occurrence patterns and propagation speeds) that need to be explained by means of an interdisciplinary effort; (2) geographical epidemic indicators confirmed in a rigorous quantitative manner the partial findings of isolated reports and time series that Black Death mortality was two orders of magnitude higher than that of bubonic plague; (3) modern bubonic plague is a rural disease hitting harder the small villages in the countryside whereas Black Death was a devastating epidemic that indiscriminately attacked large urban centres and the countryside, and while the epidemic in India lasted uninterruptedly for five decades, in Western Europe it lasted three and a half years; (4) the epidemics had reverse areal extension features in response to annual seasonal variations. Temperature increase at the end of winter led to an expansion of infected geographical area for Black Death and a reduction for bubonic plague, reaching a climax at the end of spring when the infected area in Western Europe was always larger than in India. Conversely, without exception, the infected area during winter was larger for the Indian bubonic plague; (5) during the

    The infrasound stations of the International Monitoring System (IMS) have a relatively coarse geographical coverage. Even when taking national infrasound stations which are not part of the IMS into account, the inter-station spacing is still in the range of several hundreds of kilometers. For tasks involving the recovery of dynamic properties of the source and hence the understanding of the atmospheric propagation conditions of the infrasonic waves, it is important to validate the methods applied in infrasound modeling, in particular for shorter distances. The shadow zone that exists for paths between the tropospheric and stratospheric ducts thereby poses the most significant difficulty. A field study has been performed utilizing six single infrasound sensors along the great circle path between a known source (DLR engine test facility, Lampoldshausen) and a nearby receiver (BGR infrasound array I26, Bavarian Forest) covering a distance of about 320km in total. The recordings gathered give new possibilities in studying the evolution of the infrasonic wave-field to regional distances and, in particular, through the shadow zone by comparing measured signals with modeling results. In this study we thus aim at testing and improving our infrasound modeling, especially the prediction of shadow zones in ray-tracing. For numerical modeling the ray-tracer HARPA/DLR is used. Compared to its original version HARPA/DLR was improved by the integration of adequate atmospheric temperature and wind fields (ECMWF weather forecast data for altitudes up to 80km, statistical values given by the MSISE00 (temperature) and HWM07 (horizontal wind) climatologies for greater heights). The modeling shows shadow zones which extend from about 20-40km to some 130-170km for the months from December 2011 to March 2012, in good agreement with the observations. However, the modeling effort for April and May 2012 shows a much broader shadow zone, which is less conforming to the observations. Our

    COPHES/DEMOCOPHES has its origins in the European Environment and Health Action Plan of 2004 to "develop a coherent approach on human biomonitoring (HBM) in Europe". Within this twin-project it was targeted to collect specimens from 120 mother-child-pairs in each of the 17 participating European countries. These specimens were investigated for six biomarkers (mercury in hair; creatinine, cotinine, cadmium, phthalate metabolites and bisphenol A in urine). The results for mercury in hair are described in a separate paper. Each participating member state was requested to contract laboratories, for capacity building reasons ideally within its borders, carrying out the chemical analyses. To ensure comparability of analytical data a Quality Assurance Unit (QAU) was established which provided the participating laboratories with standard operating procedures (SOP) and with control material. This material was specially prepared from native, non-spiked, pooled urine samples and was tested for homogeneity and stability. Four external quality assessment exercises were carried out. Highly esteemed laboratories from all over the world served as reference laboratories. Web conferences after each external quality assessment exercise functioned as a new and effective tool to improve analytical performance, to build capacity and to educate less experienced laboratories. Of the 38 laboratories participating in the quality assurance exercises 14 laboratories qualified for cadmium, 14 for creatinine, 9 for cotinine, 7 for phthalate metabolites and 5 for bisphenol A in urine. In the last of the four external quality assessment exercises the laboratories that qualified for DEMOCOPHES performed the determinations in urine with relative standard deviations (low/high concentration) of 18.0/2.1% for cotinine, 14.8/5.1% for cadmium, 4.7/3.4% for creatinine. Relative standard deviations for the newly emerging biomarkers were higher, with values between 13.5 and 20.5% for bisphenol A and

    Study Design Prospective observational study. Objective To determine whether preference-based health utility scores for common spinal radiculopathies vary by specific spinal level. Methods We employed a standard gamble study using the general public to calculate individual preference-based quality of life for four common radiculopathies: C6, C7, L5, and S1. We compared utility scores obtained for each level of radiculopathy with analysis of variance and t test. Multivariable regression was used to test the effects of the covariates age, sex, and years of education. We also reviewed the literature for publications reporting EuroQol-5 Dimensions (EQ-5D) scores for patients with radiculopathy. Results Two hundred participants were included in the study. Average utility for the four spinal levels fell within a narrow range (0.748 to 0.796). There were no statistically significant differences between lumbar and cervical radiculopathies, nor were there significant differences among the different spinal levels (F = 0.0850, p = 0.086). Age and sex had no significant effect on utility scores. There was a significant correlation between years of education and utility values for S1 radiculopathy (p = 0.037). On review of the literature, no study separated utility values by specific spinal level. EQ-5D utilities for both cervical and lumbar radiculopathy were considerably lower than the results of our study. Conclusions Utility values associated with the most common levels of cervical and lumbar radiculopathy do not significantly differ from each other, validating the current practice of grouping utility by spinal segment rather than by specific root levels. The discrepancy in average utility values between our study and the EQ-5D highlights the need to be mindful of the underlying instruments used when assessing outcomes studies from different sources.

The purpose of that study was {open_quotes}to conduct a systematic engineering evaluation of a variety of mixed low level waste (MLLW) treatment system alternatives.{close_quotes} The study also {open_quotes}identified the research and development, demonstrations, and testing and evaluation needed to assure unit operability in the most promising alternative system.{close_quotes} This study evaluated ten primary thermal treatment technologies, organized into complete {open_quotes}cradle-to-grave{close_quotes} systems (including complete engineering flow sheets), to treat DOE MLLW and calculated mass balances and 20-year total life cycle costs (TLCC) for all systems. The waste input used was a representative heterogenous mixture of typical DOE MLLW. An additional study was conducted, and then, based on response to these studies, additional work was started to investigate and evaluate non-thermal treatment options on a footing comparable to the effort devoted to thermal options. This report attempts to present a summary overview of the thermal and non-thermal treatment technologies which were examined in detail in the process of the above mentioned reviews.

    Aim of the study To determine the cost-effectiveness of lung cancer (LC) screening with low-dose computerised tomography of the chest, as compared to an approach without screening, reimbursed today by the National Health Fund (NHF) in Poland. Material and methods In order to analyse the current costs of diagnostic and therapeutic procedures of a model LC patient treated today, a model group consisting of 199 consecutive patients diagnosed and treated in the Oncology Centre in Bydgoszcz, Poland from January 2007 to April 2010 was used. The number and type of performed procedures in this group was obtained from the Polish Register of Neoplasms and the NHF. Only direct medical costs were analysed. To calculate the total costs of screening, diagnostics, and treatment of the hypothetical LC patient who would have cancer diagnosed with screening CT, data from the literature and costs calculated for the model group were used. Prices of procedures were obtained from the price list of the NHF on 30 April 2010 and did not change from that time until June 2014. One-way sensitivity analysis was performed. Results The average cost per LC patient, diagnosed and treated without screening, is 5567.50 EUR, and median LC-specific survival is one year. In the hypothetical LC patient with cancer diagnosed by screening, the average cost is 13689.35 EUR per LC patient, with a median LC-specific survival of at least seven years. A calculated incremental cost-effectiveness ratio (ICER) is 1353.64 EUR/year of life gained. Conclusions Lung cancer screening with low-dose CT would be highly cost-effective in Poland.

    The aim of the performed research was to determine catchments under the nitrogen pressure in Poland in period of 2007-2010. National Water Management Authority in Poland uses the elaborated methodology to fulfil requirements of Nitrate Directive and Water Framework Directive. Multicriteria GIS analysis was conducted on the base on various types of environmental data, maps and remote sensing products. Final model of real agricultural pressure was made using two components: (i) potential pressure connected with agriculture (ii) the vulnerability of the area. The agricultural pressure was calculated using the amount of nitrogen in fertilizers and the amount of nitrogen produced by animal breeding. The animal pressure was based on the information about the number of bred animals of each species for communes in Poland. The spatial distribution of vegetation pressure was calculated using kriging for the whole country base on the information about 5000 points with the amount of nitrogen dose in fertilizers. The vulnerability model was elaborated only for arable lands. It was based on the probability of the precipitation penetration to the ground water and runoff to surface waters. Catchment, Hydrogeological, Soil, Relief or Land Cover maps allowed taking into account constant environmental conditions. Additionally information about precipitation for each day of analysis and evapotranspiration for every 16-day period (calculated from satellite images) were used to present influence of meteorological condition on vulnerability of the terrain. The risk model is the sum of the vulnerability model and the agricultural pressure model. In order to check the accuracy of the elaborated model, the authors compared the results with the eutrophication measurements. The model accuracy is from 85,3% to 91,3%.

    Monitoring, mapping and modelling of mining induced terrain deformations are important tasks for quantifying and minimising threats that arise from underground extraction of useful minerals and affect surface infrastructure, human safety, the environment and security of the mining operation itself. The number of methods and techniques used for monitoring and analysis of mining terrain deformations is wide and expanding with the progress in geographical information technologies. These include for example: terrestrial geodetic measurements, Global Navigation Satellite Systems, remote sensing, GIS based modelling and spatial statistics, finite element method modelling, geological modelling, empirical modelling using e.g. the Knothe theory, artificial neural networks, fuzzy logic calculations and other. The presentation shows the results of numerical modelling and mapping of mining terrain deformations for two cases of underground mining sites in SW Poland, hard coal one (abandoned) and copper ore (active) using the functionalities of the Deformation Information System (DIS) (Blachowski et al, 2014 @ http://meetingorganizer.copernicus.org/EGU2014/EGU2014-7949.pdf). The functionalities of the spatial data modelling module of DIS have been presented and its applications in modelling, mapping and visualising mining terrain deformations based on processing of measurement data (geodetic and GNSS) for these two cases have been characterised and compared. These include, self-developed and implemented in DIS, automation procedures for calculating mining terrain subsidence with different interpolation techniques, calculation of other mining deformation parameters (i.e. tilt, horizontal displacement, horizontal strain and curvature), as well as mapping mining terrain categories based on classification of the values of these parameters as used in Poland.

    Previous studies have suggested that the process of transmigration has detrimental effects on the body image of migrants relative to women in the country of origin. In the present work, we examined the body image of Polish migrants in Britain (n=153), Polish women in Poland (n=153), and a comparison group of British White women (n=110). Participants completed a measure of actual-ideal weight discrepancy and the Body Appreciation Scale (BAS). Contrary to hypotheses, our results showed that Polish women in Poland had significantly higher weight discrepancy than their counterparts in Britain. Further analyses showed that the BAS reduced to two dimensions among Polish participants, with Polish participants in Poland having significantly lower body appreciation than Polish migrants. We suggest that the sociocultural changes that have taken place in Eastern Europe may place women in that region at relatively high risk for developing negative body image. PMID:23972729

    An analysis of wastewater from Krakow (Poland) for the presence of controlled and uncontrolled stimulant drugs of abuse was performed. Samples were collected from the Plaszow wastewater treatment plant, Krakow, Poland, and prepared by solid phase extraction. The LC-QTOFMS method was applied for identification and quantification of popular stimulants: MDMA, mephedrone, 4-MEC, MDPV and mCPP. Environmental loads of illicit drugs were calculated; the WWTP discharged loads ranging from 3.6 to 6.7 mg day(-1) 1000 inhabitants(-1) of MDMA, 3.6 to 7.1 mg day(-1) 1000 inhabitants(-1) of mephedrone and 4.8 to 5.8 mg day(-1) 1000 inhabitants(-1) of 4-MEC. The results confirmed the growing popularity of new psychoactive substances in Poland. PMID:27365137

    The aim of this article is to show specific demographic processes and accompanied transformations of settlement structure in eastern Poland at the turn of the 21st cent. Eastern Poland, covering Lubelskie, Podkarpackie, Podlaskie, Świętokrzyskie and Warmińsko-Mazurskie voivodeships, acquired the features of peripheral area in terms of communication and socio-economic aspects as a result of long-lasting historical processes. Unfavourable demographic processes can be observed in eastern Poland. They are accompanied by changes in settlement structure. Depopulation has significant social and economic consequences. The process increases social polarization between different regions in the country and between rural and urban areas. Moreover, the outflow of young and most active population to other regions or abroad is an important barrier for economic revival in peripheral regions. Consequently, unfavourable socio-economic structure in these areas is consolidated or even strengthened. This primarily concerns Lubelskie and Podlaskie voivodeships.

  8. Private Education in Poland: Breaking the Mould?

    Klus-Stanska, Dorota; Olek, Hilary

    1998-03-01

    The burgeoning private sector is perhaps the most tangible of the changes in education which followed the upheavals of 1989/90 in Central and Eastern Europe. This article sets out to analyse the growth of private education in Poland and its contribution to the ongoing processes of democratisation and educational development. The authors argue that the euphoria of the period immediately following the overthrow of one-party communism encouraged unrealistic expectations of educational reform. Their analysis of private sector schooling in Poland suggests that its development has occurred in a haphazard fashion, reflecting the uncertainties of a society undergoing a painful process of transition. Symptomatic of this has been the failure to establish a clear regulatory framework for the private sector - an omission which has undermined the credibility of private schools. Nevertheless, the authors argue that the development of private sector schooling in Poland has brought diversity and a degree of innovation to a system previously almost devoid of either. There is now an urgent need for the evaluation and dissemination of private sector initiatives, which can serve as examples for future educational decision-making in Poland.

    Chosen problems of law implementation in the contemporary process of building's modernization in Poland. One of the major problems in the contemporary process of building's modernization in Poland is the pluralism of different interpretations of chosen legal terms, existing in the contemporary building code. Incorrect interpretation, results in the incorrect application to the authorities for the proper building permit and as the effect, it causes the lost of time and money. The article tries to identify some of these problems and seeks the solution to solve them, through the evolutionary method of building law creation.

  18. Comparing offshore wind farm wake observed from satellite SAR and wake model results

    NASA Astrophysics Data System (ADS)

    Bay Hasager, Charlotte

    2014-05-01

    Offshore winds can be observed from satellite synthetic aperture radar (SAR). In the FP7 EERA DTOC project, the European Energy Research Alliance project on Design Tools for Offshore Wind Farm Clusters, there is focus on mid- to far-field wind farm wakes. The more wind farms are constructed nearby other wind farms, the more is the potential loss in annual energy production in all neighboring wind farms due to wind farm cluster effects. It is of course dependent upon the prevailing wind directions and wind speed levels, the distance between the wind farms, the wind turbine sizes and spacing. Some knowledge is available within wind farm arrays and in the near-field from various investigations. There are 58 offshore wind farms in the Northern European seas grid connected and in operation. Several of those are spaced near each other. There are several twin wind farms in operation including Nysted-1 and Rødsand-2 in the Baltic Sea, and Horns Rev 1 and Horns Rev 2, Egmond aan Zee and Prinses Amalia, and Thompton 1 and Thompton 2 all in the North Sea. There are ambitious plans of constructing numerous wind farms - great clusters of offshore wind farms. Current investigation of offshore wind farms includes mapping from high-resolution satellite SAR of several of the offshore wind farms in operation in the North Sea. Around 20 images with wind farm wake cases have been retrieved and processed. The data are from the Canadian RADARSAT-1/-2 satellites. These observe in microwave C-band and have been used for ocean surface wind retrieval during several years. The satellite wind maps are valid at 10 m above sea level. The wakes are identified in the raw images as darker areas downwind of the wind farms. In the SAR-based wind maps the wake deficit is found as areas of lower winds downwind of the wind farms compared to parallel undisturbed flow in the flow direction. The wind direction is clearly visible from lee effects and wind streaks in the images. The wind farm wake cases

    The compliance of microvascular anastomosis is an important predictive factor for long term patency of graft or vascular reconstruction. This experimental study compare the compliance of manual suture and laser assisted end to end microvascular anastomosis. In nine New-Zealand white rabbits we performed manual end-to-end suture anastomosis on the left femoral artery and laser assisted anastomosis on the right femoral artery, with a diode laser (wavelength 988 nm, power output 500 mW). Compliance was obtained by echotracking (CBI 8000 sonomicrometry system with 20 MHz implantable microprobe from Crystal-Biotech, USA) on the anastomosis site as well as upstream, and downstream from the anastomosis. Vessel compliance was lower on the manual suture side compared to the laser assisted anastomosis side, especially downstream from the anastomosis.

  20. Comparative application of different risk assessment models and implications on resulting remediation options.

    PubMed

    2014-01-01

    The issue of contaminated soils and their productive recovery is a quite controversial environmental and economic problem with important consequences for its social, public health and sustainability aspects. The sheer number and characteristics of the polluted sites are so large and varied, and the definition of priorities related to their remediation interventions so site-dependent, that proper characterization and final environmental quality goals reflect a strategic importance. One of the possible approaches to site specific approach and site priority ranking can be that of carrying out, respectively, absolute and comparative analysis procedures. An important aspect to be solved is represented by the necessity to consider not only the potential risk to public health, but also the best possible financial return from the investments for remediation, especially when carried out with public money. In this paper, different contaminated sites' risk assessment approaches are considered, compared and their applicability to support sustainable policies discussed using a case study. PMID:24645457

    2009-06-01

    This article reports a study of the relation between narcissism as a personality characteristic and the cultural dimension of individualism/collectivism. Participants from a more collectivistic society (Poland; n = 167) were compared with participants from a more individualistic society (The Netherlands; n = 156). Two dimensions of narcissism were distinguished: overt and covert. The cultural tendency for narcissism was measured by comparing average scores on both types of narcissism in both countries, as well as by the meaning that overt and covert narcissism seems to have for psychological well-being. More specifically, the correlations were compared among both types of narcissism and depression and meaning of life. In the Polish sample, the average score on covert narcissism was higher. In the Dutch sample, on the other hand, depression and meaning of life were significantly related to covert narcissism. PMID:19708410

    Rhodococcus equi is an important bacterial pathogen in foals up to 6 months old, widespread in horse farms all over the world. It was found that only virulent R. equi strains expressing 15-17 kDa virulence-associated protein (VapA) and having large virulence plasmid of 85-90 kb containing vapA gene are pathogenic for horses. To date, 12 plasmid types have been reported in VapA positive strains from horses. There are no data concerning plasmid types of Polish field R. equi strains isolated from horses and horse farm environment. The aim of the study is to determine plasmid profiles of virulent R. equi strains isolated in Poland from dead foals as well as from soil samples taken from horse breeding farms. Plasmid profiles of 10 clinical strains derived from 8 farms and 11 environmental strains from 3 farms, confirmed as virulent by PCR, were compared with 12 reference strains containing the known plasmid size and type. Plasmid DNAs were analysed by digestion with the restriction endonucleases BamHI, EcoRI, EcoT22I, and HindIII for detailed comparison and estimation of plasmid sizes. The results of RFLP analysis revealed that all except one isolates used in the study are classified as VapA 85 kb type I plasmid. One strain harboured VapA 87 kb type I plasmid. This is the first report of plasmid types of Polish field R. equi strains. The results of our preliminary investigations on horse farms located in central and eastern Poland indicate that the virulent R. equi strains thus far isolated from diseased foals and horse farms environment represent a highly uniform plasmid pattern.

    This paper presents the results of a blind comparison of top ten search results retrieved by Google.ch (French) and Khresmoi for everyone, a health specialized search engine. Participants--students of the Faculty of Medicine of the University of Geneva had to complete three tasks and select their preferred results. The majority of the participants have largely preferred Google results while Khresmoi results showed potential to compete in specific topics. The coverage of the results seems to be one of the reasons. The second being that participants do not know how to select quality and transparent health web pages. More awareness, tools and education about the matter is required for the students of Medicine to be able to efficiently distinguish trustworthy online health information. PMID:25160174

    A method for the in-vivo measurement of wear resistance of restorative materials is described. A profilometer is used to record the reduction in vertical dimension of the test material's occlusal surface. This loss of substance is calculated as the wear resistance index. The technique was used in a 13 month clinical evaluation of 3 different restorative materials, Adaptic, Amalgam (Dispersalloy) and Estic microfill. The procedure is simple in execution and very accurate. Statistical analysis has shown significant differences in wear resistance of the examined materials independent of patient variation. Attrition and abrasion were definitely greater with a standard composite material (Adaptic) than with amalgam and a test composite (Estic microfill). The newly developed composite material utilizing extremely fine filler particles of pyrogenic SiO2 (Estic microfill) was shown to be comparable to amalgam in wear resistance during the 13-month test period.

    1975-01-01

    The attitude of a spacecraft is determined by specifying independent parameters which relate the spacecraft axes to an inertial coordinate system. Sensors which measure angles between spin axis and other vectors directed to objects or fields external to the spacecraft are discussed. For the spin-stabilized spacecraft considered, the spin axis is constant over at least an orbit, but separate solutions based on sensor angle measurements are different due to propagation of errors. Sensor-angle solution methods are described which minimize the propagated errors by making use of least squares techniques over many sensor angle measurements and by solving explicitly (in closed form) for the spin axis coordinates. These methods are compared with star observation solutions to determine if satisfactory accuracy is obtained by each method.

    Despite the long-standing history of transplantation, the shortage of organs has remained its most restrictive factor. In 2010, the number of actual deceased organ donors in Poland was 13.5/million population (pmp). However, a huge difference in organ recovery rates is evident between various regions, eg, 32 pmp, in western Pomerania compared with 1-3 pmp in southern districts. A substantial number of patients who die while awaiting organ transplantations could be saved were effective programs able to overcome barriers in deceased organ donation. Such programs, eg, the European Donor Hospital Education Program, Donor Action, European Training Program on Organ Donation, United States Collaborative in Donation were introduced several years ago, but after transient improvements there has not been real progress. A new comprehensive program-Regional Partnership for Transplantation-was initiated a year ago in 4 districts of southern Poland by the Polish Union for Transplantation Medicine. The letter of intent to activate the donation program was signed by the local administration, the president of the local medical school, president of the Physician's Chamber, transplant centers, the Polish Union for Transplantation, and the Polish Transplant Coordinating Center. The plan of action included training of in-hospital coordinators, visits to all regional hospitals in company of a representative of the hospital founding body, examination of the real donation pool and the need for participation in a donation program training and education of the hospital staff in legal and organizational aspects of donation, brain death recognition, and various aspects of donor care. In addition, the program included communication skills workshops for intensive care unit physicians (with participation of 2 actors, an experienced anesthesiologist, and a psychologist), lectures for high school and university students and for hospital chaplains as well as alumni of higher seminaries.

    Cognitive abilities likely evolved in response to specific environmental and social challenges and are therefore expected to be specialized for the life history of each species. Specialized cognitive abilities may be most readily engaged under conditions that approximate the natural environment of the species being studied. While naturalistic environments might therefore have advantages over laboratory settings for cognitive research, it is difficult to conduct certain types of cognitive tests in these settings. We implemented methods for automated cognitive testing of monkeys (Macaca mulatta) in large social groups (Field station) and compared the performance to that of laboratory housed monkeys (Laboratory). The Field station animals shared access to four touch screen computers in a large naturalistic social group. Each Field station subject had an RFID chip implanted in each arm for computerized identification and individualized assignment of cognitive tests. The Laboratory group was housed and tested in a typical laboratory setting, with individual access to testing computers in their home cages. Monkeys in both groups voluntarily participated at their own pace for food rewards. We evaluated performance in two visual psychophysics tests, a perceptual classification test, a transitive inference test, and a delayed matching to sample memory test. Despite differences in housing, social environment, age, and sex, monkeys in the two groups performed similarly in all tests. Semi-free ranging monkeys living in complex social environments are therefore viable subjects for cognitive testing designed to take advantage of the unique affordances of naturalistic testing environments.

    A comparative multicenter clinical trial of two low-dose combined oral contraceptives (OCs) was conducted in Malaysia, Egypt, Thailand, and Mexico. Efficacy, safety and acceptability were investigated in women taking either a norgestrel-based (NG) OC or a norethindrone acetate-based (NA) OC. This paper includes analysis of 892 women, all of whom were at least 42 days but within 26 weeks postpartum and randomly allocated to one of the above OCs. Follow-up visits were scheduled at 1, 4, 8 and 12 months after admission. Baseline sociodemographic characteristics were similar for both groups, as well as compliance. There were nine unintended pregnancies reported; eight of these occurring in the NA group. Adverse experiences were minor with headaches and dizziness being the most common complaints; frequency of reports was similar in both groups. The group taking the NG-based OC had significantly (p < .05) fewer menstrual-related complaints. Discontinuations due to menstrual problems were significantly more common among NA users (primarily amenorrhea). Discontinuations in the NG group were primarily for other personal reasons, e.g. unable to return to the clinic. There was also a significant difference between the two groups for the 11-month gross cumulative life table discontinuation rates due to menstrual problems (p < .01); the NA group had the higher rate.

    1985-01-01

    The fire/smoke alarm response of a condensation nuclei fire detector (CNFD) was compared with photoelectric and ionization detectors. Tests were conducted in a former control room 8.5 m by 8.9 with a 2.7 m ceiling. The room had air supplied from above the ceiling and under the floor with return air exiting from ceiling grills. The environment was varied from 278 to 305 K and relative humidities from 8 to 65%. Four detection zones were located in the room. Each zone contained a sampling head for the CNDF, a photodetector, and an ionization detector so that each detector system had four opportunities to alarm during tests. The particle level in the test room was also monitored during tests with a condensation nuclei particle counter. The CNFD responded to 90% of exposures to smoldering plastic and 84% of exposures to visible fire. The photoelectric response was 43 and 12.5% respectively for the same conditions. The ionization response was 9 and 48 respectively.

    This was a prospective, open-label, nonrandomized pilot study to evaluate efficacy and tolerability of levalbuterol (LEV) in acute asthma. Asthmatics (forced expiratory volume in 1 second [FEV1], 20-55% predicted) were sequentially enrolled into cohorts of 12 to 14 and received 0.63, 1.25, 2.5, 3.75, or 5.0 mg LEV or 2.5 or 5.0 mg racemic albuterol (RAC) every 20 minutes x 3. After the first dose, FEV1 changes were 56% (0.6 L) for 1.25 mg LEV and 6% (0.07 L) and 14% (0.21 L) for 2.5 and 5 mg RAC respectively. After three doses, FEV1 changes were 74% (0.9 L), 39% (0.5 L), and 37% (0.6 L) for 1.25 mg, LEV 2.5 mg, RAC and 0.63 mg LEV respectively. LEV doses greater than 1.25 mg did not further improve bronchodilation. Baseline plasma (S)-albuterol levels were negatively correlated with baseline FEV1 (R = - 0.3, P = .004) and percent change in FEV1 (R = -0.3, P = .006). LEV at a dose of 1.25 mg produced effective bronchodilation that was greater than both RAC doses. The negative correlation between (S)-albuterol levels and FEV1 could suggest a deleterious effect of (S)-albuterol. Larger comparative studies are warranted. PMID:14724875

    A series of TOMS instruments (on November 7 , Meteor 3, and Earth Probe) has been monitoring the annual development of the Antarctic ozone hole since the 1980s. The ozone mapping instrument on Aura, OMI, is expected to take over this record of observation from the aging Earth Probe TOMS instrument. The area of the ozone hole can be taken as a sensitive indicator of the magnitude of ozone destruction each year. The timing of initial formation of the ozone hole and its duration are sensitive to the atmospheric dynamics of the southern polar regions. The entire TOMS data record (1978 - 2004) has recently been reprocessed with the new version 8 algorithm, which includes a revised calibration. The effect has been to slightly increase ozone hole area over earlier estimates, but only by 23%. OMI (ozone monitoring instrument) on Aura is a hyperspectral imaging instrument that operates in a pushbroom mode to measure solar backscattered radiation in the ultraviolet and visible. OMI has higher spatial resolution than TOMS - 14 x 24 km versus 38 km x 38 km from TOMS. OMI has now begin mapping total column ozone on a global basis in a measurement similar to TOMS. The ozone hole measurements for 2003 are compared with those from Earth Probe TOMS.

    Constant changes in society and the public health domain force public health professionals into new roles and the development of new competencies. Public health professionals will need to be trained to respond to this challenge. The aim of this comparative study among Poland, the UK and the Netherlands is to identify competence needs for Master of Public Health graduates entering the labour market from a European perspective. A self-administered questionnaire was sent to employers in the three countries, rating the importance of competency in public health on a master's level. In all three countries, interpersonal competencies, like team working and communication skills, are rated as highly important. However, employers in the UK and Poland generally rate public health specific competencies as much more important than their Dutch colleagues. It is concluded that while public health specific knowledge is providing a useful starting point for entry-level public health professionals, employers increasingly recognise the value of generic competencies such as communication and team working skills. The results suggest a stronger emphasis on teaching methods that encourage active learning and the integration of skills, which is crucial for enhancing graduates' employability, and foster an open attitude to multidisciplinary working, which is essential in modern health care.

    This paper presents the results of official control of pesticide residues in minor crops collected in southeastern Poland in 2013-2014. Compliance of used pesticides with applicable law was also verified, and determined residues were compared to maximum residue levels (MRLs) provided for in Regulation (EC) No. 395/2005. A total of 583 samples of 25 different types of fresh fruit and vegetables were analyzed for pesticide residues. Pesticide residues were detected in 158 samples (27.1 % of the analyzed samples). According to the European Commission Health & Consumer Protection Directorate-General (SANCO) guidelines document, MRL violations were understood as cases where a residue level exceeded the MRL after the uncertainty of the method (50 %) was considered. MRL violations were found in four samples. The usage of unauthorized pesticides was detected in 5.8 % of analyzed samples. Substances banned in Poland were found in two samples. Fungicides were the most frequently detected group of pesticides. Pesticide residues were most commonly found in fruit samples (19.4 % of all analyzed samples), mainly in gooseberry, redcurrant, and huckleberry. The majority of samples were compliant with MRLs, which means that they were suitable for trade. PMID:27251221

    This paper presents the problem of the hydropower plant oblique water inflow and its influence on the turbines operation. Oblique water inflow on the low head hydropower plant with bulb turbines influences turbine characteristics. The characteristics change occurs due to swirl incidence in the turbine inlet which spreads to the guide vanes inlet. Downstream, the flow conditions change is caused in the turbine runner in relation to the flow conditions without swirl inflow. Special attention is paid to the phenomenon of swirl flow incidence in the turbine conduit. With the aim of presenting and analyzing the oblique water inflow consequences on the hydropower plant operation, the existing turbine model tests results, performed in the laboratories, and the in situ prototype testing results have been used.

    Anthropogenic production of reactive nitrogen (Nr) has drastically altered the nitrogen cycle over the past few decades by causing it to accumulate in the environment. A nitrogen footprint (NF) estimates the amount of Nr released to the environment as a result of an entity's activities. The Nitrogen Footprint Tool (NFT) for universities and institutions provides a standardized method for quantifying the NF for the activities and operations of these entities. The NFT translates data on energy use, food purchasing, sewage treatment, and fertilizer use to the amount of Nr lost to the environment using NOx and N2O emission factors, virtual nitrogen factors (VNFs) for food production, N reduction rates from wastewater treatment, and nitrogen uptake factors for fertilizer. As part of the Nitrogen Footprint Project supported by the EPA, seven institutions (colleges, universities, and research institutions) have completed NFT assessments: University of Virginia, University of New Hampshire, Brown University, Dickinson College, Colorado State University, Eastern Mennonite University, and the Marine Biological Laboratory. The results of these assessments reveal the magnitude of impacts on the global nitrogen cycle by different activities and sectors, and will allow these institutions to set NF reduction goals along with management decisions based on scenarios and projections in the NFT. The trends revealed in early analysis of the results include geographic differences based on regional energy sources and local sewage treatment, as well as operational differences that stem from institution type and management. As an example of the impact of management, the amount and type of food served directly impacts the food production NF, which is a large percentage of the total NF for all institutions (35-75%). Comparison of these first NF results will shed light on the primary activities of institutions that add Nr to the environment and examine the differences between them.

    Obstetric brachial plexus injuries (OBPP) are a relatively common stretch injury of the brachial plexus that occurs during delivery. Roughly 30 % of patients will not recover completely and will need a surgical repair. Two main treatment strategies have been used: primary surgery, consisting in exploring and reconstructing the affected portions of the brachial plexus within the first few months of the patient's life, and secondary procedures that include tendon or muscle transfers, osteotomies, and other orthopedic techniques. Secondary procedures can be done as the only surgical treatment of OBPP or after primary surgery, in order to minimize any residual deficits. Two things are crucial to achieving a good outcome: (1) the appropriate selection of patients, to separate those who will spontaneously recover from those who will recover only partially or not at all; and (2) a good surgical technique. The objective of the present review is to assess the published literature concerning certain controversial issues in OBPP, especially in terms of the true current state of primary and secondary procedures, their results, and the respective roles each plays in modern-day treatment of this complex pathology. Considerable published evidence compiled over decades of surgical experience favors primary nerve surgery as the initial therapeutic step in patients who do not recover spontaneously, followed by secondary surgeries for further functional improvement. As described in this review, the results of such treatment can greatly ameliorate function in affected limbs. For best results, multi-disciplinary teams should treat these patients. PMID:26615411

    For decades, monochromatic large-scale ultralow frequency (ULF) waves with a period of about 30 s have been observed upstream of the quasi-parallel bow shock. These waves typically propagate obliquely with respect to the interplanetary magnetic field (IMF), while the growth rate for the instability causing the waves is maximized parallel to the magnetic field. It has been suggested that the mechanism for the oblique propagation concerns wave refraction due to the spatial variability of the suprathermal ions, originating from the E × B drift component. We investigate the ULF foreshock under a quasi-radial IMF with Vlasiator, which is a newly developed global hybrid-Vlasov simulation solving the Vlasov equation for protons, while electrons are treated as a charge-neutralizing fluid. We observe the generation of the 30 s ULF waves and compare their properties to previous literature and multipoint Time History of Events and Macroscale Interactions during Substorms (THEMIS) spacecraft observations. We find that Vlasiator reproduces the foreshock ULF waves in all reported observational aspects. We conclude that the variability of the density and velocity of the reflected back streaming ions determines the large-scale structure of the foreshock, which affects the wave frequency, wavelength, and oblique propagation. We conclude that the wave refraction may also be at work for radial IMF conditions, which has earlier been thought of as an exception to the refraction mechanism due to the small E × B drift component. We suggest that additional refraction may be caused by the large-scale spatial variability of the density and velocity of the back streaming ions.

    An analysis of 129 patients with 131 squamous cell carcinomas of the supraglottic larynx treated between October 1964 and April 1987 with radiotherapy alone or radiotherapy followed by neck dissection is presented. All patients had a minimum 2-year follow-up. Patients were excluded from analysis of disease control at the primary site and/or neck if they died within 2 years of treatment with the site(s) continuously disease-free. Local control rates with radiotherapy and ultimate local control rates, including patients successfully salvaged after a local recurrence, were as follows: T1, 13 of 13 and 13 of 13; T2, 34 of 42 (81%) and 37 of 42 (88%); T3, 25 of 41 (61%) and 34 of 41 (83%); and T4, 3 of 9 and 6 of 9. There was no significant difference in local control rates when comparing patients who were anatomically suitable for a supraglottic laryngectomy with those who would have required a total laryngectomy. Local control rates were slightly diminished in patients with T2-T3 lesions who had impaired or absent vocal cord mobility. The overall rates of ultimate local control with voice preservation for the entire series of 129 patients were as follows: T1, 100%; T2, 87%; T3, 69%; and T4, 57%. Cause-specific survival rates at 5 years by stage were I, 2 of 2; II, 10 of 12 (83%); III, 9 of 13 (69%); IVA, 4 of 6; and IVB, 7 of 22 (32%). The incidence of severe complications was 4 of 115 (3%) for T1-T3 lesions and 4 of 14 (29%) for T4 lesions.

    We evaluated the exposure to pesticides from the consumption of passion fruits and subsequent human health risks by combining several methods: (i) experimental field studies including the determination of pesticide residues in/on passion fruits, (ii) dynamic plant uptake modelling, and (iii) human health risk assessment concepts. Eight commonly used pesticides were applied onto passion fruits cultivated in Colombia. Pesticide concentrations were measured periodically (between application and harvest) in whole fruits and fruit pulp. Measured concentrations were compared with predicted residues calculated with a dynamic and crop-specific pesticide uptake model, namely dynamiCROP. The model accounts for the time between pesticide application and harvest, the time between harvest and consumption, the amount of spray deposition on plant surfaces, uptake processes, dilution due to crop growth, degradation in plant components, and reduction due to food processing (peeling). Measured and modelled residues correspond well (r(2)=0.88-0.99), with all predictions falling within the 90% confidence interval of the measured values. A mean error of 43% over all studied pesticides was observed between model estimates and measurements. The fraction of pesticide applied during cultivation that is eventually ingested by humans is on average 10(-4)-10(-6), depending on the time period between application and ingestion and the processing step considered. Model calculations and intake fractions via fruit consumption based on experimental data corresponded well for all pesticides with a deviation of less than a factor of 2. Pesticide residues in fruits measured at recommended harvest dates were all below European Maximum Residue Limits (MRLs) and therefore do not indicate any violation of international regulatory thresholds.

    Statistical analysis of the daily course of exposures to TL-01 tube radiation for 93 psoriatic patients from the Medical University of Łódź during 20-day phototherapy shows that the dose of 1 J/cm(2) represents a unit of single exposure necessary for psoriasis healing. This value is converted to the antipsoriatic effective dose of 317.9 J/m(2) using the TL-01 lamp irradiance spectrum and the antipsoriatic action spectrum. It is proposed that the daily exposure of 317.9 J/m(2) serves as the standard antipsoriatic dose (SAPD) providing a link between the cabinet and the out-door exposures and it could be used for planning heliotherapy in Poland. A model is proposed to calculate ambient antipsoriatic doses for 3 h exposures around the local noon (9 am-12 am GMT) based on satellite measurements of ozone and cloud characteristics. The model constants are determined by a comparison with pertaining antipsoriatic doses measured by the Brewer spectrophotometer in central Poland. It is found that 3 h exposures to solar radiation in the period 15 May-15 September provides the mean (2005-2013) doses in the range 2.7-3.1 SAPD over Poland. Thus, heliotherapy could be treated as an alternative to the cabinet phototherapy for almost 4 months. It seems that the most effective site for antipsoriatic heliotherapy is the south/east part of Poland (the Bieszczady Mountains). The heliotherapy could be carried out in existing national health centers equipped with the standard easy-to-use biometers for on-line monitoring of UV level and controlling duration of sunbathing to avoid erythema risks. It is even possible to control the antipsoriatic heliotherapy by a patient himself, using low-cost hand-held instruments measuring UV index. PMID:25116946

    The photoluminescence of selected halite crystals from Bochnia Salt Mine (Bochnia, Poland) were discovered in 2014. This is a result of contemporary precipitation from percolating waters. In most cases the fluorescence is observed in whole crystals or in zones of crystals. Only clear parts of transparent crystals are orange-red fluorescent in short UV light (320 nm). Chemical microanalysis by scanning electron microscopy/energy dispersive spectroscopy SEM/EDS indicates that this is activated by Mn and Pb. The concentration of Mn is similar in fluorescent and inactive salt and equals to 0.13 - 0.27 wt.%. The concentration of Pb, however, averages to 3.8 wt.% in fluorescent parts reaching only 1.9 wt.% elsewhere. There is no difference in the unit cell parameters determined by powder X-ray diffraction. The percolating waters contain some Mn (ca. 3.9 ppm) but the concentration of Pb is below the detection limits. The experiments of precipitation of halite from the solutions containing various concentrations of Mn and Pb were performed to simulate this fenomenon using solutions containing: 1 mg Pb/L and 80 mg Mn/L; 1 mg Pb/L and 0.8 mg Mn/L; 1 mg Pb/L and 0.6 mg Mn/L; and 0 mg Pb/L and 80 mg Mn/L. The results indicate that fluorescence is apparent when halite forms from solutions containing more than 0.8 mg Mn/L and more than 1 mg Pb/L. The presence of lead as co-activator is necessary requirement: Mn alone does not activate the fluorescence of halite. This is in accordance with the results of previous work (Murata et al., 1946; Sidike et al., 2002). Rock salt in the mine does not show fluorescence at all. Fluorescence of contemporary salt in Bochnia salt mine is a result of mining activity and slight, sporadic contamination with traces of Mn and Pb.

    ANITA (Analysing Interferometer for Ambient Air) is a flight experiment precursor for a permanent continuous air quality monitoring system on the ISS (International Space Station). For the safety of the crew, ANITA can detect and quantify quasi-online and simultaneously 33 gas compounds in the air with ppm or sub-ppm detection limits. The autonomous measurement system is based on FTIR (Fourier Transform Infra-Red spectroscopy). The system represents a versatile air quality monitor, allowing for the first time the detection and monitoring of trace gas dynamics in a spacecraft atmosphere. ANITA operated on the ISS from September 2007 to August 2008. This paper summarizes the results of ANITA s air analyses with emphasis on comparisons to other measurements. The main basis of comparison is NASA s set of grab samples taken onboard the ISS and analysed on ground applying various GC-based (Gas Chromatography) systems.

    This paper presents the situation of the profession of medical physicists in Poland. The official recognition of the profession of medical physicist in Polish legislation was in 2002. In recent years, more and more Universities which have Physics Faculties introduce a medical physics specialty. At present, there are about 15 Universities which offer such programmes. These Universities are able to graduate about 150 medical physicists per year. In 2002, the Ministry of Health introduced a programme of postgraduate specialization in medical physics along the same rules employed in the specialization of physicians in various branches of medicine. Five institutions, mostly large oncology centres, were selected as teaching institutions, based on their experience, the quality of the medical physics professionals, staffing levels, equipment availability, lecture halls, etc. The first cycle of the specialization programme started in 2006, and the first candidates completed their training at the end of 2008, and passed their official state exams in May 2009. As of January 2016, there are 196 specialized medical physicists in Poland. Another about 120 medical physicists are undergoing specialization. The system of training of medical physics professionals in Poland is well established. The principles of postgraduate training and specialization are well defined and the curriculum of the training is very demanding. The programme of specialization was revised in 2011 and is in accordance with EC and EFOMP recommendations. PMID:27378393

    Evaluating various algorithms for the inter-subject registration of brain magnetic resonance images (MRI) is a necessary topic receiving growing attention. Existing studies evaluated image registration algorithms in specific tasks or using specific databases (e.g., only for skull-stripped images, only for single-site images, etc.). Consequently, the choice of registration algorithms seems task- and usage/parameter-dependent. Nevertheless, recent large-scale, often multi-institutional imaging-related studies create the need and raise the question whether some registration algorithms can 1) generally apply to various tasks/databases posing various challenges; 2) perform consistently well, and while doing so, 3) require minimal or ideally no parameter tuning. In seeking answers to this question, we evaluated 12 general-purpose registration algorithms, for their generality, accuracy and robustness. We fixed their parameters at values suggested by algorithm developers as reported in the literature. We tested them in 7 databases/tasks, which present one or more of 4 commonly-encountered challenges: 1) inter-subject anatomical variability in skull-stripped images; 2) intensity homogeneity, noise and large structural differences in raw images; 3) imaging protocol and field-of-view (FOV) differences in multi-site data; and 4) missing correspondences in pathology-bearing images. Totally 7,562 registrations were performed. Registration accuracies were measured by (multi-)expert-annotated landmarks or regions of interest (ROIs). To ensure reproducibility, we used public software tools, public databases (whenever possible), and we fully disclose the parameter settings. We show evaluation results, and discuss the performances in light of algorithms’ similarity metrics, transformation models and optimization strategies. We also discuss future directions for the algorithm development and evaluations. PMID:24951685

    We reduce measurements made by the Active Magnetosphere and Planetary Electrodynamics Response Experiment (AMPERE) to give the total Birkeland (field-aligned) current flowing in both hemispheres in monthly and hourly bins. We analyze these totals using 6 years of data (2010-2015) to examine solar zenith angle-driven variations in the total Birkeland current flowing in both hemispheres, simultaneously, for the first time. A diurnal variation is identified in the total Birkeland current flowing, consistent with variations in the solar zenith angle. A seasonal variation is also identified, with more current flowing in the Northern (Southern) Hemisphere during Bartels rotations in northern (southern) summer. For months close to equinox, more current is found to flow in the Northern Hemisphere, contrary to our expectations. We also conduct the first test of the Milan (2013) model for estimating Birkeland current magnitudes, with modifications made to account for solar contributions to ionospheric conductance based on the observed variation of the Birkeland currents with season and time of day. The modified model, using the value of ΦD averaged by Bartels rotation (scaled by 1.7), is found to agree with the observed AMPERE currents, with a correlation of 0.87 in the Northern Hemisphere and 0.86 in the Southern Hemisphere. The improvement over the correlation with dayside reconnection rate is demonstrated to be a significant improvement to the model. The correlation of the residuals is found to be consistent with more current flowing in the Northern Hemisphere. This new observation of systematically larger current flowing in the Northern Hemisphere is discussed in the context of previous results which suggest that the Northern Hemisphere may react more strongly to dayside reconnection than the Southern Hemisphere.

  14. Flexible Survival Strategies of Pseudomonas aeruginosa in Biofilms Result in Increased Fitness Compared with Candida albicans *

    The majority of microorganisms persist in nature as surface-attached communities often surrounded by an extracellular matrix, called biofilms. Most natural biofilms are not formed by a single species but by multiple species. Microorganisms not only cooperate as in some multispecies biofilms but also compete for available nutrients. The Gram-negative bacterium Pseudomonas aeruginosa and the polymorphic fungus Candida albicans are two opportunistic pathogens that are often found coexisting in a human host. Several models of mixed biofilms have been reported for these organisms showing antagonistic behavior. To investigate the interaction of P. aeruginosa and C. albicans in more detail, we analyzed the secretome of single and mixed biofilms of both organisms using MALDI-TOF MS/MS at several time points. Overall 247 individual proteins were identified, 170 originated from P. aeruginosa and 77 from C. albicans. Only 39 of the 131 in mixed biofilms identified proteins were assigned to the fungus whereby the remaining 92 proteins belonged to P. aeruginosa. In single-species biofilms, both organisms showed a higher diversity of proteins with 73 being assigned to C. albicans and 154 to P. aeruginosa. Most interestingly, P. aeruginosa in the presence of C. albicans secreted 16 proteins in significantly higher amounts or exclusively among other virulence factors such as exotoxin A and iron acquisition systems. In addition, the high affinity iron-binding siderophore pyoverdine was identified in mixed biofilms but not in bacterial biofilms, indicating that P. aeruginosa increases its capability to sequester iron in competition with C. albicans. In contrast, C. albicans metabolism was significantly reduced, including a reduction in detectable iron acquisition proteins. The results obtained in this study show that microorganisms not only compete with the host for essential nutrients but also strongly with the present microflora in order to gain a competitive advantage.

  15. Comparing the results of bed load transport equations to field measurements in an Alpine river

    Transport processes play a decisive role in fluvial systems when sediment is carried from source to sink. In a mountain river reach the morphologic development is basically determined by the bed load transport. Attempts to observe bed load entrainment and movement directly in the field are often complicated through difficulties in spatial and temporal variability and a necessary field effort. For this reason the development of sediment transport equations has a long history. A variety of such formulae has appeared since the first "modern" equation of DU BOYS (1879) was presented. Each of them is based on one of the following approaches: shear stress, stream discharge, stochastic function for sediment movement or stream power. Many of these equations have been developed on the basis of flume data or field data sets from specific river reaches. Therefore a critical consideration of their application to other natural streams is essential. A lack of available field data is undoubtedly the cause for a deficiency of such testing. (GOMEZ & CHURCH 1989; HABERSACK & LARONNE 2002; MARTIN 2003) In this study a selection of sediment transport equations is tested against data sets of 50 field observations from the Partnach River, in the Reintal Valley, Germany, in the years 2008-2011. At the outlet of this alpine catchment the channel bed is characterized by a gradient of 2 % and a median grain size of 24 mm. Bed load samples were taken using the Helley-Smith sampler at flow rates ranging from 1.0 - 5.9 m3/s. According to these data evaluations performance and feasibility of transport equations for field applications are checked. Up to now the results between observed and calculated transport rates show a large scatter of more than several orders of magnitude. This underlines the statements from GOMEZ AND CHURCH (1989) that most equations under/over predict transport rates if the basic requirements (steady flow, equilibrium load), which are usually assumed, are not fulfilled.

  16. Comparing two fish sampling standards over time: largely congruent results but with caveats

    1. We sampled Lake Bourget (surface area = 44 km2) using CEN standard gillnet and provisional standard acoustic survey methods over 3 years (2005, 2010 and 2011) as the fish community responded to re-oligotrophication. A total of 16 species were caught in benthic gillnets and three species in pelagic gillnets. 2. Lake Bourget results were consistent with a recent study (Emmrich et al., Freshwater Biology, 57, 2012, 2436) showing strong correspondence between average biomass-per-unit-effort (BPUE) in standard benthic gillnets and average acoustic volume backscattering when smaller lakes (0.25–5.45 km2) were treated as sample units. 3. The BPUE of whitefish (Coregonus lavaretus), perch (Perca fluviatilis) and roach (Rutilus rutilus) measured by benthic gillnets all declined significantly with increasing bathymetric depth; 93% of nets set at depths >50 m caught zero fish. 4. Pelagic gillnetting indicated that small (20 m) increased significantly after 2005. 5. Both surveys showed whitefish biomass increased significantly during the study, but whitefish ≥25 cm were poorly represented in benthic gillnet catches. Contrary to the acoustic findings, the BPUE of perch and roach in benthic gillnets did not vary significantly over time. This metric is insensitive to changes in size structure in that a high catch of small fish and a low catch of large fish in different years can provide similar average BPUE estimates. 6. We examined correlations between BPUE in benthic gillnets and acoustic methods at fine spatial scales by averaging acoustic backscattering measurements encompassed by buffers of varying size (250–2000 m) around individual gillnets and by averaging samples collected from lake quadrants. Correlations at fines scales were generally poor, and only in 1 year was the quadrant correlation significant. The lack of correlation can be explained, in part, by the two gears sampling different components of the fish community. Conversely, in pelagic habitat, where the

    Alkalinity generation in the sediment of the southern North Sea is the focus of several recent studies. One motivation for these efforts is the potentially enhanced buffering capacity of anthropogenic CO2 invasion into the corresponding pelagic system. An adaptation of a global multilayer sediment model (Heinze et al., 1999) in combination with a pelagic ecosystem model for shelf sea dynamics was used to study the benthic reactions on very different annual cycles (2001 - 2009) including the River Elbe summer flooding in 2002. The focus of this study is the efflux of alkalinity, their different contributors (aerobic respiration, denitrification, net sulfate reduction, calcite dissolution, nitrification) and their seasonal and interannual cycles. Similar to the observations covering the southern North Sea (Brenner et al., 2015) the model results show large horizontal gradients from the near-shore high productive areas with benthic remineralization up to Rmin = 10.6 mol C m‑2 yr‑1 and TA generation RTA = 2 mol C m‑2 yr‑1 to off-shore moderate productive areas with mean Rmin = 2.5 mol C m‑2 yr‑1 and mean TA generation RTA = 0.4 mol C m‑2 yr‑1. Beside calcite dissolution, aerobic respiration (producing ammonium) and denitrification are the largest contributors to alkalinity generation. Nitrification is reducing alkalinity in the sediment. Due to low regenerated primary production in summer, the year 2001 exhibits the lowest input of particulate organic matter into the sediment (POCexp=2.3 mol C m‑2 yr‑1), while the year 2003 exhibits the highest export production (POCexp=2.6 mol C m‑2 yr‑1). The biogeochemical reactions and the effluxes from the sediment follow these pelagic amplitudes with a time lag of about one year with damped amplitudes.

  18. Vaccination against hepatitis viruses in Poland.

    2001-03-21

    At present, two etiologic varieties of viral hepatitis (VH) can be directly vaccine-preventable: VH type A and VH type B. In addition, VH type D can be prevented indirectly through vaccination against VH-B. The first commercially available vaccine against VH-B appeared in 1981 and was human plasma-derived. After several years, it has generally been replaced by a recombinant type of vaccines. The obvious benefits of vaccination against VH-B prompted its introduction into the national immunization program in Poland in 1989. At that time, vaccination was offered free of charge to high-risk groups: newborns of HBsAg-carrier mothers, health-care workers, students: at medical schools, nursing schools, medical technology schools, and caretakers at institutions for mentally retarded persons. However, similarly to the experiences of other countries, observations in Poland indicated that such a targeted strategy fails to induce major epidemiological changes. In 1989 and in 1993, the incidence of VH-B per 100000 was 40.3 and 34.6, respectively. In addition, during these years, the incidence of V-B per 100000 children aged 0-4 years was 20.0 and 38.4, respectively. It has been decided that vaccination against VH-B will be obligatory for all newborns beginning from 1993. Due to financial constraints, it has been introduced in three phases, and since 1996, all newborns in Poland have been vaccinated. Already in 1993, three additional risk groups have been offered vaccination: patients with chronic diseases, patients awaiting planned surgery, and persons coming into close contact with acute VH-B or chronically HBV-infected individuals. In 1999, the incidence of VH-B per 100000 was 9.1/100000, and it may be assumed that vaccination helped to decrease the incidence of VH-B in Poland. The country experience with vaccination against VH-A is still limited. At present, it is recommended for children and adolescents and people dealing with food distribution, as well as for several other

    The paper is a subjective yet critical authors' description of arbitrarily chosen series of events associated with the development of optical fibre technology (OFT) in Poland. There are reminding pioneering research activities in the second half of the seventies in Optical Fibre Technological Centres in Lublin (UMCS), in Warsaw (in ONPMP), which were joined soon after by Białystok (Polytechnics and Glass Works). There are mentioned with friendliness the key persons of that period, and in particular the pioneers of OFT in Poland, which are not with us anymore. There is emphasized the role of the first national symposia on "Optical Fibres and Their Applications", which played an integration role for the newly established research community of OFT and photonics. Omitting the complex history of the development of OFT in Poland during the intermediate years, we bravely jump to today, a day which would have not existed now, if the pioneering period had not been so rich in research results. The authors would like to show in particular these research, scientific and logistic activities, which despite difficult conditions of science development in Poland, when looked at from some distance in time and space, seemed to be then well ahead of their time.

    Persistent organochlorine compounds were used in agriculture and industry for years. Their ability to accumulate in organisms constituting links of the food chain and a unique chemical stability made them a hazardous environmental contaminants. The metabolism and excretion of chlorinated hydrocarbons is a very slow process. One of the most important means of elimination such compounds from the woman`s body is lactation. Consequently, human milk has occasionally a significant concentration of organochlorine compounds. Such compounds are identified in women`s milk all over the world. The objective of this study was to identify organochlorine pesticides, HCB, and PCBs concentrations in human milk in Poland by comparing more and less industrialized regions. 15 refs., 3 tabs.

  1. Use of flavoured cigarettes in Poland: data from the global adult tobacco survey (2009–2010)

    2014-01-01

    Background Nowadays the European Union faces a debate on the ban of sale of flavoured cigarettes. There is growing evidence that certain subgroups of smokers are more vulnerable to the use of flavoured cigarettes. However in some European countries, figures on the use of these cigarettes are still scarce. The aim of the study was to assess the prevalence of flavoured cigarettes use in Poland, and examine whether its use among adults varies by socio-demographic characteristics. Methods Data on tobacco use including flavoured cigarettes and other characteristics were derived from the Global Adult Tobacco Survey (GATS). GATS is a cross-sectional, household survey implemented in Poland between 2009 and 2010. GATS provided data on a representative sample of 7,840 individuals covering 2,254 current smokers. Logistic regression model was used to obtain odds ratios (ORs) and 95% confidence interval (CI) of the selected socio-economic variables on the use of flavoured cigarettes. Results Among females the aromatized cigarettes use was 26.1% compared to 10.5% in males (OR = 2.3; 95% CI: 1.62–3.2; p ≤ 0.001). Respondents aged 20–29 years had an increased likelihood of using flavoured cigarettes compared to subjects aged 60 years or older (OR = 2.7; 95% CI: 1.1–6.5; p ≤ 0.001). Respondents aware of negative health consequences of smoking had OR = 1.4 95% CI: 1.1–2.1 (p ≤ 0.05) of smoking aromatized cigarettes compared to those who were unaware. Participants who perceived some kinds of cigarettes less harmful than others were also more likely to use flavoured cigarettes compared to subjects who were convinced that all cigarettes are equally harmful (OR = 1.4; 95% CI: 1.1–1.8; p ≤ 0.01). High educational attainment, living in large cities, being non-economically active was also associated with use of flavoured cigarettes. Conclusion Our results are consistent with majority of epidemiology studies on this topic to date and

    The occurrence of Demodex kutzeri Bukva, 1987 was examined and compared in red deer coming from different populations--25 red deer from northern Poland (Masurian Lake District) and 25 from southern Poland (Lower Silesia). The total prevalence of infestation in red deer by D. kutzeri was 52% with the mean intensity of 38 individuals and the intensity range of 1-135. Parameters of infestation for red deer from northern Poland were much higher (68%, 49), while for other red deer--lower (36%, 16). Demodectic mites D. kutzeri are associated with common hair follicles, therefore they can be found in different parts of the body, however most of the specimens were found in the head skin. Regardless of the location and the infestation rate (including density of mites in the skin), infestations were not accompanied by symptoms of demodecosis. PMID:24171302

    109 sera from patients in the early phase of acute hepatitis non-B were tested by immunoenzymatic methods for presence of serologic markers of infections with HBV, HAV and CMV. The analysis of the results showed that 14 patients were infected with HBV, 20 with HAV and 2 with CMV. The remaining 73 cases could apparently be attributed to the infection with HCV. It has been estimated that in 1988, 69.5% of hepatitis cases in Poland could have resulted from the infection with HBV, 24%--from the infection with NANB viruses and only, and only 6.5%--from the infection with HAV. These data even if representing a slight overestimate of the incidence of hepatitis due to the parenteral spread of infections agents support the postulate that measures to prevent these infections should be strengthened.

    This study is mainly devoted to operational meteorology, to improve tornado forecast in Poland and create a Universal Tornadic Index formula. A study is focusing on climatology of sounding-derived parameters associated with tornadoes in Poland and their potential value for tornado forecasting. The data was collected from soundings made in 10 stations in and around Poland which were closely in time and space connected with tornado occurrence. The main aim of the study was to analyze the thermodynamic and kinematic parameters derived from soundings and formulate an index. The information about tornado incidents was taken from media reports and the European Severe Weather Database for the years 1977-2012. Total of 97 tornado cases were divided according to their strength for significant (F2/F3), weak (F0/F1) and unrated cases, and also according to their environmental surface temperature, for warm (> 18 °C) and cold (< 18 °C) tornadoes. As it turned out, depending on the temperature, tornadoes tended to present different environmental conditions for tornadogenesis. In warm cases, the most important factor was instability while for cold cases it was dynamic wind field. It was also proven that significant tornadoes in Poland occur in conditions accompanied by high moisture content, moderate instability and high wind shear conditions. The results of this study were used to create a Universal Tornadic Index designed to forecast activity in warm and cold, and weak and strong tornadic environments. The quality of this index was tested for the period with increased tornado activity in Poland from 2008 to 2010.

    The pollen grains of Ambrosia spp. are considered to be important aeroallergens in parts of southern and central Europe. Back-trajectories have been analysed with the aim of finding the likely sources of Ambrosia pollen grains that arrived at Poznań (Poland). Temporal variations in Ambrosia pollen at Poznań from 1995-2005 were examined in order to identify Ambrosia pollen episodes suitable for further investigation using back-trajectory analysis. The trajectories were calculated using the transport model within the Lagrangian air pollution model, ACDEP (Atmospheric Chemistry and Deposition). Analysis identified two separate populations in Ambrosia pollen episodes, those that peaked in the early morning between 4 a.m. and 8 a.m., and those that peaked in the afternoon between 2 p.m. and 6 p.m.. Six Ambrosia pollen episodes between 2001 and 2005 were examined using back-trajectory analysis. The results showed that Ambrosia pollen episodes that peaked in the early morning usually arrived at Poznań from a southerly direction after passing over southern Poland, the Czech Republic, Slovakia and Hungary, whereas air masses that brought Ambrosia pollen to Poznań during the afternoon arrived from a more easterly direction and predominantly stayed within the borders of Poland. Back-trajectory analysis has shown that there is a possibility that long-range transport brings Ambrosia pollen to Poznań from southern Poland, the Czech Republic, Slovakia and Hungary. There is also a likelihood that Ambrosia is present in Poland, as shown by the arrival of pollen during the afternoon that originated primarily from within the country.

    Obsolete pesticides were stored in Poland from the middle sixties until the late eighties of the 20th century mostly in underground disposal sites, called "pesticide burial grounds" or "pesticide tombs". The total amount of pesticide waste and packaging materials disposed of in these landfills exceeded 20000 Mg. Typically, the content of a pesticide tomb was dominated by organochlorine pesticides (comprising 10-100% of the total waste volume) with DDT as the prevailing compound. Other pesticide types, such as phosphoroorganic, carbamate insecticides, dinitrophenols, phenoxyacids, and inorganic compounds were stored in smaller quantities, usually not exceeding 10-20% of the total waste volume. With the growing awareness of the threats that these landfills posed to the environment, the first inventory for the whole country was made in 1993 and remediation was initiated in 1999. The total amount of waste, which had to be removed from the known pesticide tombs (hazardous substances, contaminated soils, construction materials etc.) was about 100000 Mg. According to the National Waste Management Plan, the reclamation of pesticide tombs was assumed to have been finished by the end of 2010, however, this goal has not been achieved. The aim of this review is to present a historical perspective of pesticide burial grounds in Poland with an emphasis on their creation, function, inventory, and remediation. Based on unpublished reports, and other published materials of limited availability written in Polish, this review may serve as a source of information for representatives of other countries, where remediation of pesticide burial grounds is still in progress. The experience gained over a ten-year period, when restoration of pesticide tombs was implemented in Poland, reveals that there are many obstacles to this action arising not only from technical, but also from economic and social issues.

    Bovine neonatal pancytopenia (BNP), a newly emerged syndrome of discussed etiology in calves, has been diagnosed since 2006. Here we describe first cases of BNP in Poland. Between September 2008 and April 2011, 62 cases of BNP were diagnosed in dairy calves. Bleeding skin lesions were mostly pronounced in summer and early autumn. Severe thrombocytopenia was observed in all sick animals. All calves came from herds vaccinated against BVDV infection with PregSure BVD vaccine (Pfizer). Substitution of colostrum from dams of BNP positive calves with colostrum from dams from herds free of BNP was the only effective measure to avoid new cases in affected herds. PMID:23214380

    The 3D P-wave seismic velocity model was obtained by combining data from multiple studies during past 50 years. Data sources included refraction seismology, reflection seismology, geological boreholes, vertical seismic profiling, magnetotellurics and gravimetry. Use of many data sources allowed creation of detailed 3D P-wave velocity model that reaches to depth of 60 km and includes 6-layers of sediments and 3-layers of the crust. Purpose of this study is to analyze how 3D model influences local (accuracy of location and source time estimation for local events), regional (identification of wide-angle seismic phases) and global (teleseismic tomography) seismic travel times. Additionally we compare results of forward seismic wave propagation with signals observed on short period and broadband stations.

  19. The changing sexual attitudes of boys in Poland.

    1990-12-01

    Until relatively recently, boys in Poland, especially in rural areas, were encouraged to have sex before marriage, while girls were expected to remain virgin until their wedding day or at least until they were engaged to be married. Many boys therefore had sex with girls they did not intend to marry, and abstained from sex with the women they hoped to have as wives. That arrangement was accepted by both boys' parents and boys' prospective wives. Women's emancipation, migration, and changing gender roles during the 1970s, however, affected sexual attitudes and behaviors. Girls grew more sexually active and the importance of virginity decreased. Tensions between the sexes subsequently increased as folk and romantic models were replaced by the partnership model and greater adherence to Catholic sexual ethics. The increased tension is readily seen via the growing number of boys with sexual problems. Approximately 90% of boys masturbate, generally without guilt. Almost 50% of 17 year old boys in Poland have had intimate sexual contact. It is common for boys' first act of sexual intercourse to occur after consuming alcohol and generally without the use of contraception. During first sexual contacts and throughout their premarital period, 40% of boys practice coitus interruptus and 38% use no method of contraception at all. An inability among the majority of boys to find willing sex partners after their first sexual intercourse causes them by necessity to not continue having sex immediately after initiation and also to engage in sex with other boys and men. The author notes that alcohol consumption among boys prior to having sex may be their way of overcoming the fear of women, and that some boys expect their female partners to be maternal. Contraception is not widely used because methods are not well known or rejected often for religious reasons. Many young people get married as a result of unplanned premarital pregnancy.

    In the 1990s Poland began to make a transition to a free-market economy: a transition accompanied by a variety of negative socio-economic developments, most notably a rise in unemployment. The aim of this study is to shed light on the relationship between occupational status (including unemployment) and the risk of cardiovascular disease (CVD), by examining the experience of 542 men and 572 women between the ages of 40 and 50 of the town of Wroclaw in 2006. The Framingham Risk Score (FRS), which uses certain health and life-style parameters to predict the risk of major coronary problems over a 10-year period, was calculated, and the effect of occupational status on the FRS was assessed. The results showed that the FRS varied according to sex and to occupational status, with the highest FRS rating among unemployed men. Thus governmental policies to counter the adverse effects of unemployment should be developed to remedy the problem. PMID:20627735

    In this work a construction of an agent based model for studying the effects of influenza epidemic in large scale (38 million individuals) stochastic simulations, together with the resulting various scenarios of disease spread in Poland are reported. Simple transportation rules were employed to mimic individuals’ travels in dynamic route-changing schemes, allowing for the infection spread during a journey. Parameter space was checked for stable behaviour, especially towards the effective infection transmission rate variability. Although the model reported here is based on quite simple assumptions, it allowed to observe two different types of epidemic scenarios: characteristic for urban and rural areas. This differentiates it from the results obtained in the analogous studies for the UK or US, where settlement and daily commuting patterns are both substantially different and more diverse. The resulting epidemic scenarios from these ABM simulations were compared with simple, differential equations based, SIR models - both types of the results displaying strong similarities. The pDYN software platform developed here is currently used in the next stage of the project employed to study various epidemic mitigation strategies.

  3. Human exposure to pollutants in Poland

    1992-07-01

    Serious environmental problems caused by decades of mismanagement of Poland's natural resources have been brought to light in recent years. All environmental media--air, water, food, and soil--have been burdened with toxic chemicals. Some environmental problems are so severe that the sources of pollution and the mitigation techniques needed are obvious, requiring no further research, but rather common sense, monies, and determination to implement the necessary controls and mitigation procedures. This paper will not address these obvious cases. Rather it will address that spectrum of environmental problems which requires a better understanding of public health risk in order to develop effective risk management strategies. Because these problems are numerous and monies limited, policy makers will need to set priorities both for research projects and control options. Using environmental concentration data presently available from Poland (especially for air), the paper will estimate human exposures, will point out research and monitoring needs, and hopefully, will lend credence to the concept that environmental policies and risk reduction strategies will be most effective if the Total Human Exposure Concept is used as the guiding scientific principle in risk assessment and management programs.

These are: Photonics Society of Poland (PSP), Polish Committee of Optoelectronics of SEP, Photonics Section of KEiT PAN, Laser Club at WAT, and Optics Section of PTF. Each of these communities keeps slightly different specificity. PSP publishes a quarterly journal Photonics Letters of Poland, stimulates international cooperation, and organizes conferences during Industrial Fairs on Innovativeness. PKOpto SEP organizes didactic diploma competitions in optoelectronics. KEiT PAN takes patronage over national conferences in laser technology, optical fiber technology and communications, and photonics applications. SO-PTF has recently taken a decision to organize a cyclic event "Polish Optical Conference". The third edition of this conference PKO'2013 was held in Sandomierz on 30.06-04.07.2013. The conference scientific and technical topics include: quantum and nonlinear optics, photon physics, optic and technology of lasers and other sources of coherent radiation, optoelectronics, optical integrated circuits, optical fibers, medical optics, instrumental optics, optical spectroscopy, optical metrology, new optical materials, applications of optics, teaching in optics. This paper reviews chosen works presented during the III Polish Optical Conference (PKO'2013), representing the research efforts at different national institutions.

  5. [Does Poland need a population policy?].

    An attempt is made to present some important issues relative to population policy, and to prove the need for such a policy in Poland. A population policy is defined as a combination of direct and indirect actions by the state to influence the growth of the population, as well as its distribution and structure. As in most European countries, an average Polish household has 2 children, a smallpercentage of families have 3 children, and many households have no children, or only 1 child. Therefore, a probirth policy is recommended to maintain the birth rate at 2.10-2.20. However, within such a policy, a family should be free to make its own plans for reproduction. Contraceptives must be available and abortion should be permitted. Given the unsaturated market and permanent shortage of essential goods, a Polish population policy can only be considered from the perspective of a general socioeconomic policy. To pursue the goals of an efficient population policy, an acceptable standard of living should be achieved. Strategically, population policy in Poland should be aimed at creating an optimal structure that would correspond to the stable and, at some point, stationary population model. An evolutionary transition to a stable (or stationary) model should take place over 2 or 3 generations. Such structural changes should go hand-in-hand with permanent improvements in the health, welfare, and cultural life of the population. PMID:12314830

    Purpose: We have previously demonstrated that intensity-modulated radiotherapy (IMRT) with a static multileaf collimator process results in a more homogenous dose distribution compared with conventional wedge-based whole breast irradiation (WBI). In the present analysis, we reviewed the acute and chronic toxicity of this IMRT approach compared with conventional wedge-based treatment. Methods and Materials: A total of 172 patients with Stage 0-IIB breast cancer were treated with lumpectomy followed by WBI. All patients underwent treatment planning computed tomography and received WBI (median dose, 45 Gy) followed by a boost to 61 Gy. Of the 172 patients, 93 (54%) were treated with IMRT, and the 79 patients (46%) treated with wedge-based RT in a consecutive fashion immediately before this cohort served as the control group. The median follow-up was 4.7 years. Results: A significant reduction in acute Grade 2 or worse dermatitis, edema, and hyperpigmentation was seen with IMRT compared with wedges. A trend was found toward reduced acute Grade 3 or greater dermatitis (6% vs. 1%, p = 0.09) in favor of IMRT. Chronic Grade 2 or worse breast edema was significantly reduced with IMRT compared with conventional wedges. No difference was found in cosmesis scores between the two groups. In patients with larger breasts ({>=}1,600 cm{sup 3}, n = 64), IMRT resulted in reduced acute (Grade 2 or greater) breast edema (0% vs. 36%, p <0.001) and hyperpigmentation (3% vs. 41%, p 0.001) and chronic (Grade 2 or greater) long-term edema (3% vs. 30%, p 0.007). Conclusion: The use of IMRT in the treatment of the whole breast results in a significant decrease in acute dermatitis, edema, and hyperpigmentation and a reduction in the development of chronic breast edema compared with conventional wedge-based RT.

    The aim of this work was to compare 10 mostly edible aboveground and 10 wood-growing mushroom species collected near a heavily trafficked road (approximately 28,000 vehicles per 24 h) in Poland with regard to their capacity to accumulate 26 trace elements (Ag, Al, As, Au, B, Ba, Bi, Cd, Co, Cr, Cu, Fe, Ga, Ge, In, Li, Mn, Ni, Pb, Re, Sb, Se, Sr, Te, Tl, and Zn) in their fruit bodies in order to illustrate mushroom diversity in element accumulation. All analyses were performed using an inductively coupled plasma optical emission spectrometry (ICP-OES) spectrometer in synchronous dual view mode. The aboveground species had significantly higher levels of 12 elements, including Ag, As, Pb, and Se, compared to the wood-growing species. An opposite relationship was observed only for Au, Ba, and Sr. The results of principal component analysis (PCA) and hierarchical cluster analysis (HCA) implied some new relationships among the analyzed species and elements. Of the analyzed mushroom species, lead content in Macrolepiota procera would seem to pose a health risk; however, at present knowledge regarding lead bioaccessibility from mushrooms is quite limited.

    Miocene conifer wood samples from the Belchatow brown coal deposit in Poland were studied in order to discuss a range of chemical variations that occur as a result of biochemical coalification. Petrographic analysis, ultimate analysis, electron microprobe technique, and FTIR spectroscopy were used in this study. Our data show several progressive trends in functional groups distribution that take place during the wood transformation from group 1 to group 4, such as an overall increase in aromaticity, an increase in lignin/cellulose ratio, and an increase in oxygen functionalities. Other observations include an increase in aliphatic stretching and bending functionalities from groups 1 to 3; followed by a decrease in the wood of group 4; appearance of aliphatic out-of-plane bands in group 3 and increase in group 4; an increase in CH2/CH3 in group 4 compared to the other groups; and decrease in O-H groups in group 4 compared to other groups. These observations, together with other chemical and petrological observations, indicate that the progressive elimination of cellulose and modification of lignin are dominant processes of the wood transformation. ?? 2005 Elsevier B.V.

    The diffusion of ‘modern’ contraceptives—as a proxy for the spread of low-fertility norms—has long interested researchers wishing to understand global fertility decline. A fundamental question is how local cultural norms and other people's behaviour influence the probability of contraceptive use, independent of women's socioeconomic and life-history characteristics. However, few studies have combined data at individual, social network and community levels to simultaneously capture multiple levels of influence. Fewer still have tested if the same predictors matter for different contraceptive types. Here, we use new data from 22 high-fertility communities in Poland to compare predictors of the use of (i) any contraceptives—a proxy for the decision to control fertility—with those of (ii) ‘artificial’ contraceptives—a subset of more culturally taboo methods. We find that the contraceptive behaviour of friends and family is more influential than are women's own characteristics and that community level characteristics additionally influence contraceptive use. Highly educated neighbours accelerate women's contraceptive use overall, but not their artificial method use. Highly religious neighbours slow women's artificial method use, but not their contraceptive use overall. Our results highlight different dimensions of sociocultural influence on contraceptive diffusion and suggest that these may be more influential than are individual characteristics. A comparative multilevel framework is needed to understand these dynamics. PMID:25904669

    At the end of the 1980s, Poland began the transformation from an essentially one-party communist system to a politically pluralistic democratic system. These political and economic changes had major social consequences, among others unemployment and a sharp decrease in real personal income. The aim of the study was to investigate the possible relationship between stress in adult men, measured by the Allostatic Load, and the socio-economic deterioration during the first part of the economic transition. The Allostatic Load included eleven markers assessing adverse nutritional intake, cardiovascular activity, inflammatory processes, and lung, hepatic and renal functions. The results indicate a significantly higher risk of metabolic dysregulation in men examined after 1990, compared to men from previous years. After adjustment for socioeconomic variables and lifestyle variables, men examined in 1991 had a 31% greater risk of higher Allostatic Load compared with men examined in 1985 (OR=1.31; p=0.0541), in 1992, this risk was 50% greater (OR=1.50; p<0.01), and in 1993, the risk was 66% greater (OR=1.66; p<0.05). The conclusion is drawn that significantly more stressogenic factors for men were those directly connected with the financial situation of their families, than a sudden but short increase of prices for goods and services.

    The presence of pharmaceuticals in drinking water, even at very low concentrations, has raised concerns among stakeholders such as drinking-water regulators, governments, water suppliers and the public, with regard to the potential risks to humans. Despite this, the occurrence and the fate of pharmaceuticals in drinking waters of many countries (e.g. in Poland) remains unknown. There is a lack of sufficiently sensitive and reliable analytical methods for such analyses and a need for more in-depth hydrogeological analysis of the possible sources of drug residues in drinking water. In this paper, a multi-residual method for the simultaneous determination of seventeen human pharmaceuticals in drinking waters has been developed. Large-volume extractions using Speedisk extraction disks, and derivatization prior to GC-MS-SIM analysis using a new silylating agent DIMETRIS were applied. The method detection limits (MDLs) ranged from 0.9 to 5.7ng/L and the absolute recoveries of the target compounds were above 80% for most analytes. The developed method was successfully applied in the analysis of the target compounds in drinking water collected in Gdansk (Poland), and of the 17 pharmaceuticals, 6 compounds were detected at least once. During the investigation, the geomorphology of the site region was taken into account, possible sources of pharmaceuticals in the analysed drinking water samples were investigated, and the presence of the drugs in ground and surface waters, raw and treated drinking waters was determined. Concentrations were also compared with those observed in other countries. As a result, this study has not only developed a new analytical method for determining pharmaceuticals in drinking waters as well as rendering missing information for Poland (a country with one of the highest consumptions of pharmaceuticals in Europe), but it also presents a modelled in-depth hydrogeological analysis of the real sources of drugs in drinking waters.

    2005-03-01

    A new method (XRWIS) to predict the minimum road surface temperature for the winter maintenance of roads, using geomatics, has been tested in Poland. A geographical database was constructed for a 200 km test route from Krakow to the Slovakian border. A GPS survey to measure sky-view factor was carried out as part of the COST 719 project. A computer energy balance model ‘IceMiser’ was run retrospectively to predict road surface temperature every 20 minutes for every 20 m along the road using hourly weather data recorded at two adjacent climate stations: at low elevation in Krakow and at high elevation in Zakopane, in March 2003. A GIS was used to visualise the predicted road surface temperatures. The IceMiser model was verified by comparing the predicted road surface temperatures with measured road surface temperatures at a number of road weather outstations along the route. The results for four road weather outstations are discussed. The best results are for Libertow (264 m) and Myslenice (304 m) close to Krakow, whereas the results for Skawa (518 m) and Piatkowa Gora (649 m) at high elevation are not as good, probably due to their distance from the Zakopane climate station.

    Background In 1948, Professor Józef Gajek initiated a detailed census of the wild edible plants used in Poland. The questionnaires were collected by correspondents of the Polish Folklore Society in 95 localities throughout Poland. A major part of these archival materials, including a substantial collection of herbarium specimens, had not undergone thorough analysis prior to this study, which presents a quantitative analysis of this archival set of data. Methods Herbarium specimens were identified and a database was created. Results Ninety-eight taxa identified to genus or species level, including 71 botanical species, identified using herbarium specimens, were found. On average only 11 edible plant species per locality were listed, the longest list included 39 species. No correlation between latitude and the number of edible species was found, whereas there was small but significant correlation with the longitude. Fruits were the most frequently collected part of plants. Most plants were primarily collected by women and children. Children both helped parents to collect wild fruits and also ate many species raw, which were not consumed by adults, but had often been eaten in the past. Eighteen of the taxa had not been reported in a recent comprehensive review of edible plants of Poland. Stratiotes aloides, used as a famine vegetable in the Łódź region, has never been reported as edible in any ethnobotanical literature. Conclusion The results undermine the conclusions of a recent comprehensive review of edible plants of Poland, which stated that many more wild edible plants have been collected in the Carpathians than in lowland Poland. However such results were shown to be caused by the substantially larger number of ethnographic studies undertaken in the Carpathians. In fact, large numbers of edible plant species were collected in the mid-20th century in a few regions, particularly along the eastern border, in the Carpathians and in communities originating from

    Background Neisseria meningitidis is a leading etiologic agent of severe invasive disease. The objective of the study was to characterise invasive meningococcal disease (IMD) epidemiology in Poland during the last decade, based on laboratory confirmed cases. Methods The study encompassed all invasive meningococci collected between 2002 and 2011 in the National Reference Centre for Bacterial Meningitis. The isolates were re-identified and characterised by susceptibility testing, MLST analysis, porA and fetA sequencing. A PCR technique was used for meningococcal identification directly from clinical materials. Results In the period studied, 1936 cases of IMD were confirmed, including 75.6% identified by culture. Seven IMD outbreaks, affecting mostly adolescents, were reported; all were caused by serogroup C meningococci of ST-11. The highest incidence was observed among children under one year of age (15.71/100,000 in 2011). The general case fatality rate in the years 2010–2011 was 10.0%. Meningococci of serogroup B, C, Y and W-135 were responsible for 48.8%, 36.6%, 1.2% and 1.2% of cases, respectively. All isolates were susceptible to third generation cephalosporins, chloramphenicol, ciprofloxacin, and 84.2% were susceptible to penicillin. MLST analysis (2009–2011) revealed that among serogroup B isolates the most represented were clonal complexes (CC) ST-32CC, ST-18CC, ST-41/44CC, ST-213CC and ST-269CC, and among serogroup C: ST-103CC, ST-41/44CC and ST-11CC. Conclusions The detection of IMD in Poland has changed over time, but observed increase in the incidence of the disease was mostly attributed to changes in the surveillance system including an expanded case definition and inclusion of data from non-culture diagnostics.

    The area covered by magnetotelluric survey is a part of the Trans-European Suture Zone (TESZ). The TESZ is the largest tectonic boundary in Europe, extending from the British Isles through Poland to the Black Sea. Several two-dimensional (2-D) models of the electrical resistivity distribution have already been constructed for this area but it turned out that the region had a complicated, three-dimensional structure. Thus a three-dimensional (3-D) inversion model appears to be relevant and interesting to investigate. In cooperation with the Berlin Magnetotelluric Work Group several additional long-period magnetotelluric (LMT) sites were assembled in 2012 and 2013. The mesh was located in the north-west part of Poland (Pomerania region). As a result we obtained 17 new sites over the surface area of approximately of 100 km × 50 km, in addition to 9 stations set up earlier. The collected data were converted to a uniform format and the initial processing was executed. By using the latest software the transfer functions (impedances) and the ellipses of the phase tensor for the sites of our mesh have been calculated. The apparent resistivities and phase responses as functions of period are calculated from the impedance components. The computer program ModEM (Egbert G.D., Kelbert A., 2012), which is used for this work, is a parallel 3-D inversion program for magnetotelluric data. The inversion code employs MPI and, besides impedances, includes tippers and magnetic tensor. The main result of this work is a 3-D model with a good RMS fit of ~2.2 which we could compare with previous outcomes. In this model two prominent, NW-SE striking conductive lineaments located in the mid-crustal levels are noticed. These structures we relate tentatively to the Variscan and Caledonian deformation fronts. Also the analysis of the invariants of the Horizontal Magnetic Tensor (HMT) obtained from previous results (Jozwiak, 2012) allowed us to examine the TESZ in more detail.

    Since the beginnings of twenty-first century in Poland increasing number of reports about the drug-facilitated sexual assaults have been observed. Many drugs have been identified as so-called "date-rape drugs", because of their pharmacological properties, especially inducing amnesia. These drugs are used for the purpose of "drugging" unsuspected victims and than raping them. In a typical scenario, the perpetrator surreptitiously adds "date-rape drug" to the alcoholic or non-alcoholic beverage of an unsuspecting person, who is subsequently sexually assaulted while under the influence of this substance. Many victims do not report the incident until several days after the event or even do not report it at all. They report the incident so late after the events because they often have problems with remember the course of incident. It causes that victim is not reliable witness for justice. Detection of "date-rape drugs" in biological fluids is unequivocal evidence of perpetration. Analysis of biological fluids collected from victims of rapes for presence of drugs was rare in Poland up to now. The aim of this study is to show the use of "date-rape drugs" in Poland. Materials for this study were from the routine casework elaborated at the Institute of Forensic Research in Kraków. APCI-LC-MS methods were applied for screening of biological fluids (blood and/or urine) for amphetamine and its 6 analogues, for 12 substances from benzodiazepine group and for quantification of the detected drugs. HPLC-DAD was used as a screening method for wide range of medicinal drugs, and NCI-GC-MS methods for determination of ketamine and tetrahydrocannabinols (delta9-tetrahydrocannabinol, 9THC) and its metabolite (11-nor-carboxy-delta9-tetrahydrocannabinol, THCCOOH). In 2000-2004, the biological fluids taken from 33 persons, both sexually assaulted or perpetrators were analysed. In 2000 and 2002 not any case of this type was registered, in 2001 only two cases were recorded. After 2003

    The welfare of captive bears became a big issue of concern in Poland when a case of a bear being ill-treated became a high-profile case in the media. This case created a challenge to verify, study, and understand the main problems associated with bear keeping so that zoos could significantly improve the conditions in which they keep bears or ensure they keep bears at the minimum required standards. The results presented here are from 1 of the few countrywide studies of captive bear conditions conducted in all the captive institutions in Poland that keep bears. Thirteen institutions kept bears at the time of the study (2007-2009), including 54 individuals of 5 species. Major welfare problems were identified, and the results have been used to challenge zoos to address the changes required and focus the government's attention on areas that require legislative improvement.

    Tornadoes, or high speed rotating columns of air, are some of the most extreme natural processes occurring on Earth. Currently the trend towards more frequent and more severe occurrence of tornadoes appear also in Poland. So far, tornadoes in Poland resulted in very serious damage to infrastructure and led to injury or death many of the people. Forecast of tornados is not a easy task, especially when the phenomenon is local. Must be based on a comprehensive analysis of mesoscale numerical models, atmospheric soundings and radar data. Unfortunately, there are a number of limitations.One of it, is that the mesoscale weather models often do not capture local events, so forecast of the tornados in real time and place can not occur well in advance. The phenomenon of tornadoes must be better understood and become the object of a comprehensive analysis, so that the resulting information can be used both for research purposes as well as educational.

    The distribution of mining tremors is strictly related to the exploitation progress of mining works and, consequently, to the local stress field. In case the distribution is known, it is possible to determine future area of intensive seismicity in exploited mining panel. In the paper, an analysis of working face-to-tremor distance for Rudna copper mine in Poland is presented. In order to develop a spatial model of tremors' occurrence in the exploited mine, the seismicity of four mining sections in the five-month period was investigated and the tremors' distribution was obtained. It was compared with the spatial distribution of tremors in coal mines found in the literature. The results show that the places where tremors mostly occur — the vicinity of the face, in front of it — coincide with the high-stress area predicted by literature models. The obtained results help to predict the future seismic zone connected with planned mining section, which can be used in seismic hazard analysis.

    The genetic diversity of human immunodeficiency virus type 1 (HIV-1) offers an opportunity to track the development of the epidemic across different populations. Viral pol gene fragments from 55 individuals of Polish origin with recent HIV-1 infection identified in 2008-2010 in four Polish cities were analyzed. Viral sequences were compared with sequences from 100 individuals (reference group) infected before 2004. Viral spread among groups with different HIV transmission categories was compared using a phylogenetic approach. The majority of sequences from individuals with recent infection were subtype B (93%) within which four transmission clusters (18% of samples) were detected. Samples from men infected through sex between men and from persons infected through injecting drugs were broadly separated (P < 0.0001), while samples from individuals infected by heterosexual contacts were dispersed uniformly within phylogenetic tree (P = 0.244) inferred from viral sequences derived from individuals infected recently and the reference group. The percentage of samples from persons infected by heterosexual contacts which clustered with samples from men infected through sex between men was not significantly higher for those with recent infection (47%), compared to the reference group (36%). In conclusion, men infected by sex between men and individuals infected through injecting drugs appear to form separate HIV transmission networks in Poland. The recent spread of HIV-1 among persons infected with subtype B by heterosexual contacts appears to be linked to both these groups. PMID:23080488

    We have implemented the WRF-Chem model version 3.5 over Poland to quantify the direct and indirect feedback effects of aerosols on simulated meteorology and aerosol concentrations. Observations were compared with results from three simulations at high spatial resolutions of 5 × 5 km: (1) BASE—without any aerosol feedback effects; (2) DIR—with direct aerosol-radiative effects (3) INDIR—with direct and indirect aerosol-radiative effects. We study the overall effect during January 2011 as well as selected episodes of the highest differences in PM10 concentrations between the three simulations. For the DIR simulation, the decrease in monthly mean incoming solar radiation (SWDOWN) appears for the entire study area. It changes geographically, from about -8.0 to -2.0 W m-2, respectively for the southern and northern parts of the country. The highest changes do not correspond to the highest PM10 concentration. Due to the solar radiation changes, the surface mean monthly temperature (T2) decreases for 96 % of the area of Poland, but not more than 1.0 °C. Monthly mean PBLH changes by more than ±5 m for 53 % of the domain. Locally the differences in PBLH between the DIR and BASE are higher than ± 20 m. Due to the direct effect, for 84 % of the domain, the mean monthly PM10 concentrations increase by up to 1.9 µg m-3. For the INDIR simulation the spatial distribution of changes in incoming solar radiation as well as air temperature is similar to the DIR simulation. The decrease of SWDOWN is noticed for the entire domain and for 23 % of the domain is higher than -5.0 W m-2. The absolute differences of PBLH are slightly higher for INDIR than DIR but similarly distributed spatially. For daily episodes, the differences between the simulations are higher, both for meteorology and PM10 concentrations, and the pattern of changes is usually more complex. The results indicate the potential importance of the aerosol feedback effects on modelled meteorology and PM10

    Research of medical gases is well established in Poland and has been marked with the foundation of several professional societies. Numerous academic centers including those dealing with hyperbaric and diving medicine conduct studies of medical gases, in vast majority supported with intramural funds. In general, Polish research of medical gases is very much clinical in nature, covering new applications and safety of medical gases in medicine; on the other hand there are several academic centers pursuing preclinical studies, and elaborating basic theories of gas physiology and mathematical modeling of gas exchange. What dominates is research dealing with oxygen and ozone as well as studies of anesthetic gases and their applications. Finally, several research directions involving noble gas, hydrogen and hydrogen sulfide for cell protection, only begin to gain recognition of basic scientists and clinicians. However, further developments require more monetary spending on research and clinical testing as well as formation of new collective bodies for coordinating efforts in this matter. PMID:23916016

    The restoration of democracy in Poland initiated a major system transformation including reform of the health sector. The international community were quick to respond to the need for assistance. Polish proposals were supported by international experts and projects were developed together with international development agencies and donors. Donors had no experience of central and eastern Europe, these countries had never been beneficiaries of aid and neither side had experience working together. Progress and absorption of funds was slow. Comparative experience from developing countries was used to analyze the barriers encountered in project development and implementation in Poland. The conditions necessary for implementation were not satisfied. Insufficient attention was paid to the project process. Barriers originate on the side of both donors and recipients and additionally from programme characteristics. The most serious problems experience in Poland were lack of government commitment to health care reform leading to failure to provide counterpart funds and low capacity for absorption of aid. Rent seeking attitudes were important. Donor paternalistic attitudes, complex procedures and lack of innovative approach were also present. Poor coordination was a problem on both sides. Multi-lateral projects were too complex and it was not always possible to integrate project activities with routine ones. External consultants played an excessive role in project development and implementation, absorbing a large portion of funds. The barriers have been operationalised to create a checklist which requires validation elsewhere and may be useful for those working in this field. PMID:10170090

    This paper describes bone marrow donation and transplantation in Poland in terms of its history, current state, and information on the quality control system. Based on data gathered from the informatics systems of the Polish Central Unrelated Potential Bone Marrow Donor and Cord Blood Registry and the Polish transplant registries, as well as World Marrow Donor Association statistics, we performed an overview study to collect and compare numbers on hematopoietic stem cells donations and transplantations in Poland in the years 2010-2014. In the last 5 years, the number of registered potential hematopoietic stem cells donors in Poland increased by more than 4 times, from about 146,000 to over 750,000. During the same period, the number of patients qualified to hematopoietic stem cells transplantation from unrelated donor increased from 557 in 2010 to 817 in 2014. We observed a striking change in the percentage of transplantations performed in Polish centers using material collected from national donors--from 24% to 60%. This shift was also evident in the number of search procedures closed with acceptation of Polish donors--from 27% in 2010 to 58% in 2014. Another consequence of Polish registry growth is the increasing number of donations from Polish donors for international patients. Between 2010 and 2014, the percent of donation for non-national patient increased from 33% to 76%, placing Poland in 6th place in the ranking of the HSC "exporters" worldwide. Growth of transplantation rates involves standardization process, which is a natural way of development for national organizations in the field of HSCT because of its international character.

    Climate change affects many natural processes and the same applies to human impact For instance climate change and anthropogenic activities may cause increased fire activity or change peatland dynamics. Currently it is still unknown how Sphagnum peatlands in the oceanic-continental transition zone of Poland may respond to combined effects of heat waves, drought and fire. The aim of the study was to reconstruct the last 2000 years palaeohydrology and fire history at Linje bog in Northern Poland. The main task was to determine the drivers of fire episodes, particularly to identify climatic and anthropogenic forcing. A two-meter peat core was extracted and subsampled with a high resolution. Micro- and macroscopic charcoal analyses were applied to determine past fire activity and the results compared with palaeohydrological reconstructions based on testate amoeba analysis. Palynological human indicators were used to reconstruct human activity. A depth-age model including 20 14C dates was constructed to calculate peat accumulation rates and charcoal influx. We hypothesised that: 1) fire frequency in Northern Poland was determined by climatic conditions (combination of low precipitation and heat waves), as reflected in peatland water table, and that 2) past fire episodes in the last millennium were intensified by human activity. Furthermore climate may have influenced human activity over harvest success and the carrying capacity. Our study shows that fire was important for the studied ecosystem, however, its frequency has increased in the last millennium in concomitance with land use activities. Landscape humanization and vegetation opening were followed by a peatland drying during the Little Ice Age (from ca. AD 1380). Similarly to other palaeoecological studies from Poland, Linje peatland possessed an unstable hydrology during the Little Ice Age. Increased fire episodes appeared shortly before the Little Ice Age and most severe fires were present in the time when

    Following the defeat of communism, Poland has witnessed an erosion in the separation between state and church, as the Roman Catholic church has begun using its immense political power to press for social legislation -- one that includes a ban on abortion and contraception. The Catholic church has already succeeded in obtaining government support of religious education (in fact, it has become the only instruction available), and in tightening divorce laws. Most of the church initiatives affect women disproportionately. As a solution for the country's unemployment, bishops suggested taking jobs from women and giving them to men. Moreover, the church's most vehement campaign has centered on family planning and abortion. Bishops have begun a campaign designed to eventually ban contraception and abortion. Despite the fact that 60% of all Poles approve of the law permitting abortion, the church successfully lobbied the Ministry of Health to impose measures requiring a woman seeking an abortion to obtain the approval of 2 gynecologists, her family doctor, and a church approved psychologist. At least 3 women have already died from self-induced abortions following the enactment of the regulations. The church has also succeeded in getting the government to stop subsidizing birth control pills. with consent from Pope John Paul II, Catholic pharmacists in Poland have refused to sell contraceptives. These measures ignore the well-known fact that contraception is the best, least coercive way to reduce the number of abortions. It appears, however, that the bishops' heavy hand has led to a decline in public support for the church. PMID:12178848

The simulation results of Zeff using Geant4 and MCNP codes have been compared with possible available experimental results and theoretical WinXcom, and good agreement has been observed. The simulated μ/ρ and Zeff values using Geant4 and MCNP code signifies that both the simulation process can be followed to determine the gamma ray interaction properties of the alloys for energies wherever analogous experimental results may not be available. This kind of studies can be used for various applications such as for radiation dosimetry, medical and radiation shielding.

    Based on a literature review concerning methane emissions in Poland, it was stated in 2009 that the National Greenhouse Inventory 2007 [13] was published. It was prepared firstly to meet Poland's obligations resulting from point 3.1 Decision no. 280/2004/WE of the European Parliament and of the Council of 11 February 2004, concerning a mechanism for monitoring community greenhouse gas emissions and for implementing the Kyoto Protocol and secondly, for the United Nations Framework Convention on Climate Change (UNFCCC) and Kyoto Protocol. The National Greenhouse Inventory states that there are no detailed data concerning methane emissions in collieries in the Polish mining industry. That is why the methane emission in the methane coal mines of Górnośląskie Zagłębie Węglowe - GZW (Upper Silesian Coal Basin - USCB) in Poland was meticulously studied and evaluated. The applied methodology for estimating methane emission from the GZW coal mining system was used for the four basic sources of its emission. Methane emission during the mining and post-mining process. Such an approach resulted from the IPCC guidelines of 2006 [10]. Updating the proposed methods (IPCC2006) of estimating the methane emissions of hard coal mines (active and abandoned ones) in Poland, assumes that the methane emission factor (EF) is calculated based on methane coal mine output and actual values of absolute methane content. The result of verifying the method of estimating methane emission during the mining process for Polish coal mines is the equation of methane emission factor EF.

    Poland syndrome is the most frequent cause of congenital breast aplasia and hypoplasia. Breast and possible chest wall deformities can be treated with several surgical techniques, including implants, and pedicled or free flaps.We describe the case of a young patient with severe Poland syndrome with amastia, athelia, and deformity of the chest wall, and aplasia of 2 ribs. Marked hypoplasia of the ipsilateral latissimus dorsi muscle ruled out a reliable reconstructive option.Two perforator flaps were performed in a single-stage operation. A hemi-deep inferior epigastric perforator flap was harvested to correct the chest deformity, whereas the contralateral superficial inferior epigastric artery flap allowed breast reconstruction.No complications occurred and a subjectively and objectively pleasing cosmetic result was maintained at 3-year follow-up.

    Human infection by Babesia microti has been recognized as an emerging zoonosis with important public health implications worldwide. In Europe the reported cases of human babesiosis have been attributed mostly to B. divergens infection, with only sporadic cases of the disease caused by B. microti or B. venatorum. This study, based on molecular methods (PCR, R-T PCR, DNA sequencing and phylogenetic analysis), reveals for the first time in Poland, asymptomatic infection with . microti in immunocompetent healthy individuals working in forest ecosystems. Of the 58 professional foresters examined, two (3.4%) were identified as B. microti-positive by specific PCR. The results of this study also provide strong evidence that in eastern Poland, where tick-borne diseases (TBDs) are endemic, there is a potential risk of acquiring human babesiosis due to zoonotic B. microti parasites commonly found in rodents and I. ricinus ticks. The potential public health importance of this finding is discussed. PMID:25780828

    Tertiary basaltic volcanics from southwest Poland which form the eastern part of the Central European Volcanic Province (CEVP) have been studied for Sr, Nd, and Pb isotopic compositions. 87Sr/86Sr ratios range from 0.70317 to 0.70369, 143Nd/144Nd ratios range from 0.51285 to 0.51302 and Pb isotopic compositions range from 19.42 to 19.94 for 206Pb/204Pb. These data indicate the influence of three end-member mantle components DMM, HIMU and EM. An analysis of all isotopic results from the CEVP leads to the conclusion that basalts from SW Poland have the most depleted character. We propose a model whereby the depleted source mantle for the CEVP interacted with enriched components (EM). The western part of the CEVP was enriched on a larger scale than the eastern part, probably due to the influence of the Rhine Graben rift.

  19. Correlation between DNA ploidy, metaphase high-resolution comparative genomic hybridization results and clinical outcome of synovial sarcoma

    Background Although synovial sarcoma is the 3rd most commonly occurring mesenchymal tumor in young adults, usually with a highly aggressive clinical course; remarkable differences can be seen regarding the clinical outcome. According to comparative genomic hybridization (CGH) data published in the literature, the simple and complex karyotypes show a correlation between the prognosis and clinical outcome. In addition, the connection between DNA ploidy and clinical course is controversial. The aim of this study was using a fine-tuning interpretation of our DNA ploidy results and to compare these with metaphase high-resolution CGH (HR-CGH) results. Methods DNA ploidy was determined on Feulgen-stained smears in 56 synovial sarcoma cases by image cytometry; follow up was available in 46 cases (average: 78 months). In 9 cases HR-CGH analysis was also available. Results 10 cases were found DNA-aneuploid, 46 were DNA-diploid by image cytometry. With fine-tuning of the diploid cases according to the 5c exceeding events (single cell aneuploidy), 33 cases were so called "simple-diploid" (without 5c exceeding events) and 13 cases were "complex-diploid"; containing 5c exceeding events (any number). Aneuploid tumors contained large numbers of genetic alterations with the sum gain of at least 2 chromosomes (A-, B- or C-group) detected by HR-CGH. In the "simple-diploid" cases no or few genetic alterations could be detected, whereas the "complex-diploid" samples numerous aberrations (equal or more than 3) could be found. Conclusions Our results show a correlation between the DNA-ploidy, a fine-tuned DNA-ploidy and the HR-CGH results. Furthermore, we found significant correlation between the different ploidy groups and the clinical outcome (p < 0.05). PMID:22053830

    Compared to other regions in Poland, the Lublin Upland and Roztocze Hills are distinguished by the density and size of gully systems. In this area, morphometric analyses using GIS tools were performed based on digital data processed from 1:10 000 topographic maps and the Digital terrain Model. The results obtained allowed distinguishing of 17 "gully regions", i.e. areas characterized by a high concentration of gully forms. The analysis of distribution of gullies in relation to other environmental elements demonstrated that the particularly intensive development of gullies in specific areas was associated with geomorphological, geological, hydrogeological, and paleogeographical factors. The anthropogenic impact, i.e. intensive, long-term agricultural management and consequent deforestation, was of great importance as well. The gully regions identified are characterized by a varied surface area and dissection density that in extreme cases reaches over 10 km/km2. From the economic point of view, the phenomenon is unfavourable, as it leads to fragmentation of arable land and intensification of erosion processes. On the other hand, gully regions offer attractive landscape and natural values, therefore some areas have been included in various protection programmes.

    One hundred and three samples of faeces of reared grey wolves from four locations (Stobnica Park and Zoological Gardens in Bydgoszcz, Wrocław and Cracow) and twenty-six samples of faeces from two free-roaming packs of grey wolf (Canis lupus L.) in Piła (Forest Divisions: Borne Sulinowo, Czarnobór, Jastrowo) and Zielona Góra (Forest Divisions: Torzym, Krosno Odrzańskie) were collected between 2005 and 2007. Helminth eggs were detected in 78.6% of faecal samples of reared grey wolves and in 88.4% of those of free-roaming wolves. The trematode Alaria alata (80.1%) and nematodes Eucoleus aerophilus (23.1%) and Spirocerca lupi (11.5%) were only detected from wild packs of wolves and the nematodes Ancylostoma caninum (35.9%), Trichuris vulpis (15.5%) and Toxocara canis (3.9%) were only detected from reared wolves. Differences were observed in the prevalence and composition of helminth fauna between reared and wild grey wolves and our results are compared with those from studies within Poland and elsewhere in Europe.

    Two joint Polish-Hungarian field campaigns were performed close beside cattle farms, near Turew (Poland), with the idea to determine energy budget components above cropland and to estimate ammonia flux. The first campaign was performed above grassland with limited fetch (close shelter belt) in June 2008, the second above arable cropland in October 2008. Turbulent fluxes were calculated using micrometeorological measurement data (standard meteorological parameters, radiation and surface energy budget components) as well as three different methods: (i) the gradient, (ii) the Bowen ratio and (iii) the eddy covariance method. Results obtained using different methodologies for flux calculations and local effects on energy budget closure were compared. During the second campaign concentration of ammonia was measured employing three different instruments: (i) a passive sampler, (ii) the AMANDA system and (iii) a diode laser based photoacoustic instrument combined with preconcentration sampling (WaSul-Flux). These measurements provide data for ammonia flux calculation on landscape scale. Data obtained using the AMANDA system and the photoacoustic instrument was used to determine vertical and horizontal distribution of ammonia concentration. Ammonia fluxes were calculated using gradient and profile method. Sensitivity analysis of the ammonia flux calculation [(i) assessment of ammonia gradient, (ii) choice of universal function, (iii) application of gradient and profile techniques], daily variations of the energy budget components and the effects of ammonia emission from the cattle farm were also investigated.

    A parasitological survey of an Asian fish, Chinese sleeper Perccottus glenii, inhabiting the Włocławek Reservoir on the lower Vistula River (central Poland) revealed the occurrence of an exotic cestode Nippotaenia mogurndae Yamaguti and Miyata, 1940, which spreads spontaneously with a host to European waters. This paper documented the first record of the parasite in Poland. Specimens were described, and the effect of fish size and season on the infection level was analyzed. Within the 3 years, 112 fish were examined. Samples were collected by electrofishing in the upper part of the Włocławek Reservoir three times (seasonally) in 2006 and 2007 and once in autumn 2008. Parasitological indices (prevalence, intensity of infection, and abundance) in particular samples as well as in two size groups of fish were calculated. Statistical tests were applied to analyze the results (Spearman's correlation coefficient and Mann-Whitney's U test). The infection level of Chinese sleeper with N. mogurndae in the Włocławek Reservoir (prevalence 54.7%, mean intensity of infection 7.2, maximum 29) was comparable to infection noted in the area of the natural range of the host. The infection of smaller fish (less than 80 mm, TL) increased gradually with increasing body size. The infection of bigger specimens was in general higher, but the parasite recruitment was of a more incidental character. The spreading of N. mogurndae with Chinese sleeper is still in progress. The Włocławek Reservoir provides suitable conditions for parasite development. PMID:19943065

    Since the XIX century human trichinellosis has remained an unsolved problem of public healthcare in Poland. This paper describes the past situation and analyses current changes in the epidemiological pattern of trichinellosis in Poland. Epidemiological data from the last 60 years, point out that the number of human cases as well as the number of deaths caused by trichinellosis has decreased significantly. Up to 90s the main source of Trichinella infection for people was pork. Among other implemented control measures, the introduction of the artificial digestion method in the early 80s to detect trichinellosis in pigs resulted in a shift in the sources of Trichinella infection in humans - pork was replaced with wild boar meat. In the years 1990-1995 the number of outbreaks due to pork consumption was 3.5-times higher than in the years 2000-2005. In the early nineties pork was the source of infection causing about 71% of all outbreaks; in 2000-2005 that number has fallen to only 12%. On the other hand wild boar meat was responsible for 23% of the outbreaks in 1990-1995 and as many as 88% of all outbreaks in the years 2000-2005. Moreover the number of persons infected in the outbreaks significantly decreased. The study of wild animals demonstrated that wild boars in Poland are infected not only with T. spiralis but also with Trichinella britovi. These results and EU recommendations indicate a requirement of determining the Trichinella species which cause infections in outbreaks. In the 3 trichinellosis outbreaks in 2005 the infected meat products were examined with molecular tools. T. spiralis species larvae were the etiological agents of infection in all these outbreaks. The current epidemiological situation of trichinellosis in Poland indicates a need of increasing the awareness of risks related to wild boar meat consumption among the general public. Introducing the artificial digestion method as an obligatory method for wild boar meat examination is also necessary

    The correct management, with the classic techniques, of the thoracic deformity in Poland's syndrome is difficult, with often insatisfactory results. The current surgical treatment involves the use of prothetic material and/or different flaps with their own complications and scares. The experience of our team with fat grafting (we named lipomodeling) in breast reconstruction helped us to propose the correction of the thoracic and mammary deformity by repeated fat transfer sessions. Fat grafting is commonly used in our team since 1998 in various indication of breast surgery. We reviewed retrospectively our ten first cases of thoracic deformity in Poland's syndrome treated with only fat grafting. Patients had repeated procedures until obtaining a satisfactory result. The fat was harvested from the thigh, buttocks, and abdomen. There were young patients with a mean age of 16years old (from 12 to 24). The mean follow-up was 51months. An average of 2.9 procedures (1 to 5) with 255cm(3) of fat injection at each procedure was needed to obtain symetry. Hundred percent of the patients were satisfied. No complication was noted. As reported, the reconstruction of the thoracic deformity and the mammary shape can be obtained by fat grafting. The absence of a flap donor site sequelae and the absence an implant allow this technique to be simple, reproductible, and without great complication. These criteria match well the surgical management of this deformity, which is mainly aesthetic. Moreover, the secondary benefit of liposuction of disgracious steatomery helps the acceptance of the procedure. Therefore in our hands, fat grafting to the breast (lipomodeling) is now our first choice treatment in thoracic Poland syndrome deformity. Given the rarity of this syndrome, we recommend a treatment by an operator who makes the learning curve of lipomodeling, and who often deals with Poland syndrome. PMID:23153632

    The aim of this study is to examine the prevalence of underweight, overweight and obesity, using International Obesity Task Force (IOTF) criteria, in four cohorts of children and adolescents living in Poland in different economic eras: communist economy (1977/1978), crisis of the 1980s (1987/1988), political and economic transformation (1992/1994) and the free market economy (2002/2004). Analysis was conducted on a database including 10,934 records for children of the age 7-18 years. In Poland, in the last 26 years of economic and political transformations, the epidemic of obesity was not noticed but the growing incidence of children and adolescents with body mass deficit was observed (p<0.0001) (20.2% of girls in 2002/2004 vs. 11.0% in 1977/1978 and 12.1% of boys in 2002/2004 vs. 7.2% in 1977/1978). Lower parental education and a higher number of children in a family resulted in a higher prevalence of underweight (odds ratio [OR] fluctuated from 1.26 to 1.63). The social effects of the political transformation in Poland significantly affected families with low socio-economic status (SES), and especially more eco-sensitive boys. This result is opposite to the trends observed in Western countries and makes an important contribution to the current knowledge of the course of further changes in weight-to-height ratio at a global scale.

    Poland belongs to the group of EU countries with the highest levels of mercury emissions, with a large portion of these emissions being related to coal combustion. This paper presents a modelling analysis of the impact that the Polish power sector has on the atmospheric concentrations of mercury. A detailed mercury emission inventory is used to analyse the concentration and deposition of mercury. For this study, a chemical scheme devoted to mercury transformations in the atmosphere was implemented into the Polyphemus air quality system. The system was then used to perform simulations for 2008 in two domains i.e. over Europe and over Poland. The impact of various parameters on concentration and wet scavenging of mercury has been analysed. The results of the mercury ambient concentrations and depositions, are presented. Additionally, the contribution of natural and anthropogenic sources to mercury deposition in Poland is shown. The performed works showed that the national sources have low impact to overall deposition, however local contribution in wet deposition of big emitters may reach 50%. Sensitive analysis showed a significant impact of reaction with bromine compound and scavenging coefficient on modelled results of mercury concentration and deposition.

    Sepsis represents a life-threatening infection requiring the immediate start of antibacterial treatment to reduce morbidity. Thus, laboratories use direct antimicrobial susceptibility testing (AST) to rapidly generate preliminary results from positive blood cultures. As the direct AST has not yet been published to be evaluated with EUCAST breakpoints, the purpose of the study was to investigate the reliability of the direct agar diffusion test to correctly produce AST results from positive monobacterial blood cultures compared with the VITEK2-based definitive AST, when current EUCAST breakpoints were used. A total of 428 isolates from unselected monobacterial routine blood cultures and 110 challenge strains were included. Direct agar diffusion-based and standard VITEK2-based AST of 2803 bacterium–drug combinations yielded a total clinical category agreement of 95.47% with 1.28% very major errors and 3.42% combined major and minor errors. On the species level, very major errors were observed in the species–drug combinations Enterococcus spp.–high-level gentamicin (10.87%) and Staphylococcus spp.–rifampicin (5%), only. No very major errors occurred with Enterobacteriaceae and Pseudomonas aeruginosa. In most species–drug combinations, the direct agar diffusion test using EUCAST breakpoints precisely predicted the result of the definitive antibiotic susceptibility test and, thus, it can be used to optimize empiric antibiotic therapy until definitive results are available.

    Background: There is currently no consensus in the literature on which embolic agent induces the greatest degree of liver hypertrophy after portal vein embolization (PVE). Only experimental results in a pig model have demonstrated an advantage of n-butyl-cyanoacrylate (NBCA) over 3 other embolic materials (hydrophilic gel, small and large polyvinyl alcohol particles) for PVE. Therefore, the aim of this human study was to retrospectively compare the results of PVE using NBCA with those using spherical microparticles plus coils. Methods: A total of 34 patients underwent PVE using either NBCA (n = 20), or spherical microparticles plus coils (n = 14). PVE was decided according to preoperative volumetry on the basis of contrast-enhanced CT. Groups were compared for age, sex, volume of the left lobe before PVE and future remnant liver ratio (FRL) (volume of the left lobe/total liver volume - tumor volume). The primary end point was the increase in left lobe volume 1 month after PVE. Secondary end points were procedure complications and biological tolerance. Results: Both groups were similar in terms of age, sex ratio, left lobe volume, and FRL before PVE. NBCA induced a greater increase in volume after PVE than did microparticles plus coils (respectively, +74 {+-} 69 % and +23 {+-} 14 %, p < 0.05). The amount of contrast medium used for the procedure was significantly larger when microparticles and coils rather than NBCA were used (respectively, 264 {+-} 43 ml and 162 {+-} 34 ml, p < 0.01). The rate of PVE complications as well as the biological tolerance was similar in both groups. Conclusion: NBCA seems more effective than spherical microparticles plus coils to induce left-lobe hypertrophy.

    Objective: To comparatively analyze the results from arthroscopic rotator cuff suture between smoking and non-smoking patients. Methods: A group of 286 patients who underwent arthroscopic suturing of primary rotator cuff injuries between June 12, 2002, and May 14, 2008, was analyzed. The patients included in the study were evaluated using the UCLA scale, with a minimum follow-up of 12 months and average of 56.52 months. The variables studied were age, sex, side operated, dominance, profile of cigarette use and UCLA index. Results: This study evaluated a total of 205 patients. Mean age (p = 0.289) and sex (p = 0.124) were analyzed statistically between the smoking and non-smoking patients and the two groups were considered to be similar. The average UCLA score for the non-smoking patients (143) was 34 (32 to 35). The average UCLA score for the smoking patients (51) was 33 (29 to 35). There was no statistically significant difference in UCLA score (p = 0.123) between the smoking and non-smoking patients. For the purposes of statistical analysis, we grouped the small and medium tears (107) and compared these with the large and extensive tears (80), between smokers and non-smokers. There was no statistically significant difference using the Mann-Whitney test regarding the small and medium tears (p = 818). There was a statistically significant difference using the Mann-Whitney test regarding the large and extended tears, between the smoking and non-smoking patients, such that the non-smokers showed better UCLA scores (p = 0.038). Conclusion: The results from arthroscopic suturing of large and extensive rotator cuff injuries are inferior among smoking patients. PMID:27027006

    Incontinence-associated dermatitis (IAD) is a common problem in elderly incontinent people. A comparative cross-sectional study was conducted to examine and compare properties of intact skin on the buttocks and subumbilicus area in elderly people wearing absorbent products and to identify pad environment factors that affect skin properties. Study participants included 45 elderly (age range: 68 to 103 years) female residents of one nursing home who were incontinent of feces and urine (dual incontinence group--DIG, n = 35) or feces only (fecal incontinence group--FIG, n= 10). Skin pH and hydration were measured and factors believed to affect the perineal environment and contribute to the development of IAD were assessed. In both DIG and FIG, skin hydration levels and pH were higher in the coccygeal than in the subumbilical area. Skin hydration of the sacral region in the DIG was significantly higher than in the FIG (P = 0.019) and skin pH on the coccygeal region and sacral region in the DIG was significantly higher than in the FIG (coccygeal region, P = 0.013; sacral region, P = 0.023). Absorbent pad surface pH (P &0.01) and excessive sweating (P = 0.006) were significantly related to skin pH. Results show that properties of perineal skin in elderly women with incontinence are affected by occlusion with pads, increasing the risk of IAD. Studies comparing the effect of various types of pads and pad-change frequencies on skin properties are needed. PMID:21205991

    In spite of widespread support from most member countries’ societies for European Union policy, including support for the sustainable development idea, in many EU countries the levels of acceptance of new environmental protection programmes have been and, in particular in new member states, still are considerably low. The experience of the countries which were the first to implement union directives show that they cannot be effectively applied without widespread public participation. The goal of this study was, using the example of Poland, to assess public acceptance of the expansion of nature conservation in the context of sustainable development principles and to discover whether existing nature governance should be modified when establishing new protected areas. The increase in protected areas in Poland has become a hotbed of numerous conflicts. In spite of the generally favourable attitudes to nature which Polish people generally have, Natura 2000 is perceived as an unnecessary additional conservation tool. Both local authorities and communities residing in the Natura areas think that the programme is a hindrance, rather than a help in the economic development of municipalities or regions, as was initially supposed. This lack of acceptance results from many factors, mainly social, historic and economic. The implications of these findings for current approach to the nature governance in Poland are discussed.

    At the time of the Second Republic of Poland, in March 1922, the city of Vilnius together with the Vilnius Region was incorporated into Poland. Sanitary and health negligence was one of the main problems of the city. The genesis of that situation dates back to the 120-year national bondage, when the city was under the Russian rule. Since 1915 it was occupied by the German invader, and from January to April 1919 it belonged to Soviet Russia. The legacy left by this epoch concerned bad housing conditions, problems with removal of impurities, scarcity of fresh water supply, uneven and dirt roads, which along with other bionegative factors resulted in dissemination of contagious diseases and occurrence of other health risks. In Vilnius of the interwar period, similarly to other big cities in Poland, sanitary surveillances played a significant role in controlling acute contagious diseases, inspecting sanitary conditions of living quarters, service outlets, industrial plants, sites of production and selling food articles, as well as surveillance of food. Municipal doctors supervised the work of sanitary inspectors in each sanitary office. PMID:19899609

    An observed increase in air temperature can lead to significant changes in the phenology of plants and, consequently, changes in agricultural production. The aim of the study was to evaluate the spatial differentiation of thermal resources in Poland and their variability during a period of changing thermal conditions in Europe. Since the variability of thermal conditions is of paramount importance for perennial crops, the study focused on apple, plum, and cherry orchard regions in Poland. The analysis was conducted for the period of 1951-2010 using air temperature daily data. Thermal resources have been defined using the growing degree days (GDD) index calculated independently for the whole year and during in frost-free season for three air temperature thresholds: 0, 5, and 10 °C, which determine the non-winter period, growing season, and the period of full plant growth, respectively. In addition, due to the high significance for perennials in particular, the incidence and intensity of frost during flowering were calculated. In this study, a detailed analysis of the spatial differentiation of thermal resources was first performed, followed by an evaluation of long-term variability and associated change patterns. The obtained results confirmed an increase in thermal resources in Poland as a consequence of the lengthening of the growing season. However, the frequency and intensity of spring frost, especially during flowering or even during ripening of plants, remain a threat to harvests in both the eastern and western parts of the country.

    While numerous ancient human DNA datasets from across Europe have been published till date, modern-day Poland in particular, remains uninvestigated. Besides application in the reconstruction of continent-wide human history, data from this region would also contribute towards our understanding of the history of the Slavs, whose origin is hypothesized to be in East or Central Europe. Here, we present the first population-scale ancient human DNA study from the region of modern-day Poland by establishing mitochondrial DNA profiles for 23 samples dated to 200 BC - 500 AD (Roman Iron Age) and for 20 samples dated to 1000-1400 AD (Medieval Age). Our results show that mitochondrial DNA sequences from both periods belong to haplogroups that are characteristic of contemporary West Eurasia. Haplotype sharing analysis indicates that majority of the ancient haplotypes are widespread in some modern Europeans, including Poles. Notably, the Roman Iron Age samples share more rare haplotypes with Central and Northeast Europeans, whereas the Medieval Age samples share more rare haplotypes with East-Central and South-East Europeans, primarily Slavic populations. Our data demonstrates genetic continuity of certain matrilineages (H5a1 and N1a1a2) in the area of present-day Poland from at least the Roman Iron Age until present. As such, the maternal gene pool of present-day Poles, Czechs and Slovaks, categorized as Western Slavs, is likely to have descended from inhabitants of East-Central Europe during the Roman Iron Age.

    Backgrounds/Aims To compare the clinical outcomes of intraoperative radiofrequency ablation (RFA) and non-anatomical hepatic resection (NAHR) for small hepatocellular carcinoma (HCC). Methods From February 2007 to January 2015, clinical outcomes of thirty four patients with HCC receiving RFA or NAHR were compared, retrospectively. Results There was no difference of patient and tumor characteristic between the two groups that received RFA or NAHR. The 1, 2, and 3-year recurrence rates following RFA were 32.2%, 32.2% and 59.3% respectively, and 6.7%, 33.3% and 33.3% following NAHR respectively (p=0.287). The 1, 2 and 3-year overall survival (OS) rates following RFA were 100%, 88.9% and 76.2% respectively, and 100%, 85.6% and 85.6%, respectively, following NAHR (p=0.869). We did not find a definite statistical difference in recurrence rate and OS rate between the two groups. In the multivariate analysis, number of tumor was an independent prognostic factor for recurrence and albumin was an independent prognostic factor for OS. Conclusions We recommend non-anatomical hepatic resection rather than intraoperative RFA in small sized HCC, due to a higher recurrence rate in intraoperative RFA. Intraoperative RFA was inferior to non-anatomical hepatic resection in terms of recurrence rate. We need to select the optimal treatment considering liver function and possibility of recurrence.

    Photointerpretation is the technique generally used to map and analyze the tectonic features existent on Mars surface. In this study we compare qualitatively and quantitatively two tectonic maps based on the interpretation of satellite imagery and a map derived semi-automatically. The comparison of the two photointerpreted datasets allowed us to infer some of the factors that can influence the process of lineament mapping on Mars. Comparing the manually mapped datasets with the semi-automatically mapped features allowed us to evaluate the accuracy of the semi-automatic mapping procedure, as well as to identify the main limitations of the semi-automatic approach to mapping tectonic structures from MOLA altimetry. Significant differences were found between the two photointerpretations. The qualitative and quantitative comparisons showed how mapping criteria, illumination conditions and scale of analysis can locally influence the interpretations. The semi-automatic mapping procedure proved to be mainly dependent on data quality; nevertheless the methodology, when applied to MOLA data, is able to produce meaningful results at a regional scale.

    In this study, the influence of traffic intensity on dew formation efficiency and chemistry is presented. The measurements were conducted near the A4 motorway in SW Poland in almost flat land relief with intense agricultural activity. The dew/hoarfrost was collected by means of insulated plain passive radiative condensers at three sites: AN and AS located in the close vicinity of the motorway (30 m) on the opposite sides of the road, and AR, representing rural background conditions beyond the motorway influence. Measurements were conducted in two short campaigns in April and September 2009 with 9 and 10 collection days respectively. The average daily efficiency of dew formation was 0.179 L/m2. Its value for AN, AS and AR was on average 0.170, 0.199 and 0.173 L/m2, respectively. The efficiency of dew formation at measurement sites located on both sides of the road differed by up to about 200% during an individual dew episode. Maximum daily value reached 0.389 L/m2. The average volume-weighted pH was acidic and ranged from 4.29 (AS) to 4.58 (AR). The electric conductivity (EC) at all measurement sites was relatively low reaching on average 55.9 μS/cm for AN, 62.2 μS/cm for AS and 35.8 μS/cm for AR. The average volume-weighted TIC parameter (total ionic content) reached the value of 0.62 meq/L (AN and AS) and 0.38 meq/L (AR). Both EC and TIC values indicated strong influence of the motorway at sites located in its close vicinity (AN and AS). Depending on airflow direction during individual dew collection events, AN or AS sites were situated alternatively on windward or leeward side of the road, which distinctly influenced dew formation and chemistry: the leeward condenser was characterized by smaller water volume, higher EC and higher TIC when compared both with its windward counterpart and the background site. The ionic structure of the collected samples was similar at all measurement sites. The largest share had NO3 - anion (28-32%) and Ca2+ cation (22-25%). Thus

    We evaluate exactly the statistical integral for an inhomogeneous one-dimensional (1D) counterion-only Coulomb gas between two charged boundaries and from this compute the effective interaction, or disjoining pressure, between the bounding surfaces. Our exact results are compared to the limiting cases of weak and strong couplings which are the same for 1D and three-dimensional (3D) systems. For systems with a large number of counterions it is found that the weak-coupling (mean-field) approximation for the disjoining pressure works perfectly and that fluctuations around the mean-field in 1D are much smaller than in 3D. In the case of few counterions it works less well and strong-coupling approximation performs much better as it takes into account properly the discreteness of the counterion charges. PMID:19275406

    In this study we examine and describe the neuroanatomical organization of sensory cortex in four rodents: laboratory Norway rats (Long Evans; Rattus norvegicus), wild-caught Norway rats (Rattus norvegicus), wild-caught California ground squirrels (Spermophilus beecheyi), and wild-caught Eastern gray squirrels (Sciurus carolinensis). Specifically, we examined the myeloarchitecture and cytochrome oxidase reactivity for several well-identified areas in visual cortex (areas 17, 18, and 19), somatosensory cortex (areas S1, S2 and PV), and auditory cortex [areas A1 + AAF (R) and TA] and compared the percentage of dorsolateral cortex devoted to each of these areas. Our results demonstrate that squirrels have a larger mean percentage of dorsolateral cortex devoted to visual areas than rats. The difference is due to the greater percentage of cortex devoted to known areas such as area 17 and area 18 and not simply to a difference in the number of visual areas, which ultimately makes this distinction even more pronounced. Furthermore, both rat groups have a larger percentage of the dorsolateral cortex devoted to somatosensory and auditory cortical areas. Differences within groups were also observed. The arboreal squirrel had a larger mean percentage of dorsolateral cortex devoted to areas 17 and 18 compared with the terrestrial squirrel. The laboratory Norway rat had a larger percentage of dorsolateral cortex devoted to both somatosensory and auditory areas than the wild-caught Norway rat. Our results indicate that differences in sensory apparatus, use of sensory systems, and niche are reflected in the organization and size of cortical areas. PMID:20886618

    The purpose of this study was to compare the midterm results of a radiological and surgical approach to uterine fibroids. One hundred twenty-one women with reproductive plans who presented with an intramural fibroid(s) larger than 4 cm were randomly selected for either uterine artery embolization (UAE) or myomectomy. We compared the efficacy and safety of the two procedures and their impact on patient fertility. Fifty-eight embolizations and 63 myomectomies (42 laparoscopic, 21 open) were performed. One hundred eighteen patients have finished at least a 12-month follow-up; the mean follow-up in the entire study population was 24.9 months. Embolized patients underwent a significantly shorter procedure and required a shorter hospital stay and recovery period. They also presented with a lower CRP concentration on the second day after the procedure (p < 0.0001 for all parameters). There were no significant differences between the two groups in the rate of technical success, symptomatic effectiveness, postprocedural follicle stimulating hormone levels, number of reinterventions for fibroid recurrence or regrowth, or complication rates. Forty women after myomectomy and 26 after UAE have tried to conceive, and of these we registered 50 gestations in 45 women. There were more pregnancies (33) and labors (19) and fewer abortions (6) after surgery than after embolization (17 pregnancies, 5 labors, 9 abortions) (p < 0.05). Obstetrical and perinatal results were similar in both groups, possibly due to the low number of labors after UAE to date. We conclude that UAE is less invasive and as symptomatically effective and safe as myomectomy, but myomectomy appears to have superior reproductive outcomes in the first 2 years after treatment.

    Purpose: Tumor hypoxia has been observed in many human cancers and is associated with treatment failure in radiation therapy. The purpose of this study is to quantify the effect of different radiation fractionation schemes on tumor cell killing, assuming a realistic distribution of tumor oxygenation. Methods and Materials: A probability density function for the partial pressure of oxygen in a tumor cell population is quantified as a function of radial distance from the capillary wall. Corresponding hypoxia reduction factors for cell killing are determined. The surviving fraction of a tumor consisting of maximally resistant cells, cells at intermediate levels of hypoxia, and normoxic cells is calculated as a function of dose per fraction for an equivalent tumor biological effective dose under normoxic conditions. Results: Increasing hypoxia as a function of distance from blood vessels results in a decrease in tumor cell killing for a typical radiotherapy fractionation scheme by a factor of 10{sup 5} over a distance of 130 {mu}m. For head-and-neck cancer and prostate cancer, the fraction of tumor clonogens killed over a full treatment course decreases by up to a factor of {approx}10{sup 3} as the dose per fraction is increased from 2 to 24 Gy and from 2 to 18 Gy, respectively. Conclusions: Hypofractionation of a radiotherapy regimen can result in a significant decrease in tumor cell killing compared to standard fractionation as a result of tumor hypoxia. There is a potential for large errors when calculating alternate fractionations using formalisms that do not account for tumor hypoxia.

    The paper presents the results of year-long measurements of radon ((222)Rn) concentration inside 129 buildings in Poland in relation to the geological conditions of their foundation. The authors took into account the division of the country into tectonic units, as well as the lithology of the rocks forming the bedrock of these buildings. As expected, the highest value of mean annual (222)Rn concentration (845 Bq/m(3)) was recorded in a building situated in the area of the Sudetes, while the highest geometric mean (characteristic of the expected log-normal data distribution) was calculated based on measurements from buildings located within the East-European craton, in the area of Mazury-Podlasie monocline, where it reached 231 Bq/m(3). Such results reflect geological conditions - the occurrence of crystalline rocks (especially U- and Ra-enriched granites and orthogneisses) on the surface in the Sudetes, and of young post-glacial sediments containing fragments of Scandinavian crystalline rocks, also enriched with U and Ra, in the area of Mazury-Podlasie monocline. However, the least expected result of the investigations was finding out that, contrary to the hitherto widespread belief, none of the major tectonic units of Poland can be excluded from the list of those containing buildings with mean annual (222)Rn concentration exceeding 200 Bq/m(3). The mean annual concentration of radon for all the buildings were much higher than the mean concentration value (49.1 Bq/m(3)) of indoor radon in Poland quoted so far. These results cast a completely new light on the necessity to perform measurements of radon concentration in residential buildings in Poland, no more with reference to small areas with outcrops of crystalline rocks (especially the Sudetes, being the Polish fragment of the European Variscan belt), but for all the major tectonic units within Poland.

    Background: Peripheral arterial disease (PAD) represents systematic atherosclerosis of great vessels. PAD affects approximately 10-20 % of patients older than 60 years and is associated with high mortality and morbidity rate debilitating individuals’ life. Objectives: To compare the results of Gadolinium enhanced MR-Angiography and surgery in patients suspected to have peripheral arterial disease. Materials and Methods: In this prospective cohort study, 30 consecutive patients matching the inclusion criteria were enrolled and MR-Angiography was performed prior to surgery for each one. Results: 22 patients were male (73.3%) and the mean age was 60.3 ± 10.6 years in our study group. The most common artery for cut off and run off was superior femoral artery in both assessments. Proximal section of each artery was the most common anatomical section for cut off and run off. There was a same report of cut off artery by MR-Angiography and surgery (kappa coefficient of agreement was 0.96, P value < 0.001) and positive predictive value was 0.97 (95% CI: 0.83-0.99). Conclusions: According to our findings MR-angiography is an appropriate alternative imaging modality for patients suspected to have peripheral arterial disease and it facilitates the early diagnosis proposed by the clinical findings. Also beneficial characteristics of this method such as low exposure to ionizing radiation, repeatability, and low risk of contrast agent-induced nephropathy make it a modality of choice in patients with renal impairment.

  7. A comparative study between experimental results and numerical predictions of multi-wall structural response to hypervelocity impact

    1992-01-01

    Over the last three decades, multiwall structures have been analyzed extensively, primarily through experiment, as a means of increasing the protection afforded to spacecraft structure. However, as structural configurations become more varied, the number of tests required to characterize their response increases dramatically. As an alternative, numerical modeling of high-speed impact phenomena is often being used to predict the response of a variety of structural systems under impact loading conditions. This paper presents the results of a preliminary numerical/experimental investigation of the hypervelocity impact response of multiwall structures. The results of experimental high-speed impact tests are compared against the predictions of the HULL hydrodynamic computer code. It is shown that the hypervelocity impact response characteristics of a specific system cannot be accurately predicted from a limited number of HULL code impact simulations. However, if a wide range of impact loadings conditions are considered, then the ballistic limit curve of the system based on the entire series of numerical simulations can be used as a relatively accurate indication of actual system response.

    1997-01-01

    A high-lift workshop was held in May of 1993 at NASA Langley Research Center. A major part of the workshop centered on a blind test of various computational fluid dynamics (CFD) methods in which the flow about a two- dimensional (2D) three-element airfoil was computed without prior knowledge of the experimental data. The results of this 'blind' test revealed: (1) The Reynolds Averaged Navier-Stokes (RANS) methods generally showed less variability among codes than did potential/Euler solvers coupled with boundary-layer solution techniques. However, some of the coupled methods still provided excellent predictions. (2) Drag prediction using coupled methods agreed more closely with experiment than the RANS methods. Lift was more accurately predicted than drag for both methods. (3) The CFD methods did well in predicting lift and drag changes due to changes in Reynolds number, however, they did not perform as well when predicting lift and drag increments due to changing flap gap, (4) Pressures and skin friction compared favorably with experiment for most of the codes. (5) There was a large variability in most of the velocity profile predictions. Computational results predict a stronger siat wake than measured suggesting a missing component in turbulence modeling, perhaps curvature effects.

    Three-dimensional photogrammetric techniques arecommonly used to generate high-resolution digital outcrop models suitable to complement stratigraphic and structural field studies. This is particularly true for near vertical outcrops were direct data collection is very difficult to perform, provided that the data are reliable. To check whether fracture attribute data acquired from photogrammetric digital outcrop models can be effectively integrate field data, we performed a multisource data acquisition programme on the master joint set affecting the Langhian part of the Marnoso Arenacea Formation, a foredeep siliciclastic turbidite succession widely exposed in the external sector of the Northern Apennines. We selected an about 90 m high vertical cliff in a meander of the Santerno River, which was surveyed by both terrestrial and drone-aided photogrammetry to produce two different digital outcrop models of the same strata. Moreover, field data were collected in the same strata along river bed exposures few hundred meters upstream. Comparison of master joint attributes, namely orientation, spacing and height, collected along linear scanlines in the field and in the two digital outcrop models shows quite comparable results, particularly when FSI (Fracture Spacing Index) values are considered. Sensitivity tests of the impact of the number of data on the statistical results from photogrammetric scanlines, where hundreds of measurements can be collected along each scan line, were also performed. Our results provide further support to the effectiveness of the integration between field and photogrammetrically-obtained structural data to study fracture densities in partially accessible exposures. Given the large data numbers that can be collected in digital outcrop models, once validated in the field, photogrammetric data allow robust statistical analysis to be performed on fracture attributes.

  10. [Thoughts on demographic optimization in contemporary Poland].

    Oledzki, M

    1980-01-01

    This article presents the viewpoint of the Polish school of social policy of the Institute of Social Economy concerning the problem of optimization of demographic structures and processes in contemporary Poland. This school was created under the leadership of the outstanding sociologist Ludwik Krzywicki (1859-1941). The reasoning concerns, first of all, the scientific premises of the choice of criteria of demographic optimization examined and then there is a critical assessment of modern simplified approaches to the definition of optimum population. It also shows actual possibilities of demographic optimization and the complexity of analytical categories of socioeconomic processes which determine the development of the population in specific time and space. In conclusion, the theory of demographic optimization is regarded as a task too ambitious and perhaps even utopian in view of the assumptions needed for its satisfactory realization. This conclusion confirms the thesis contained in the handbook of demography by J.Z. Holzer published in 1970. The author considers, however, that the search for a theory of demographic optimization is still a task which mobilizes social sciences to an integration centered on demography and social policy.

    Introduction Breast cancer is the most common malignant tumour among women. About 15,000 new cases of breast cancer are diagnosed and more than 5,000 women die in Poland every year. The aim of this study was to analyse the incidence and mortality rate of breast cancer among women in Poland in the years 2001-2010. Material and methods Analysed data concerning the incidence of and mortality from cancer among women were obtained from the National Cancer Registry. Results The number of new cases reported in 2010 exceeded that reported in 2001 by 3,666. The mortality from breast cancer among women increased by 15.1% by 2009, to subsequently drop by 0.3% in 2010. The standardized incidence rate increased by 7.4 and the standardized mortality rate fell by 1.3 in 2001-2010. Conclusions In the years 2001-2010 the incidence of breast cancer in women in Poland rose by 30.3%, with an increase of 7.4 in the incidence rate. The highest rise in the incidence and mortality of women due to breast cancer in Poland is reported in the Lodz voivodeship. In the years 2001-2009 the number of women's deaths due to breast cancer increased slightly, while the mortality rate dropped. PMID:26327877

    Objectives To investigate the prevalence of comorbidities in early rheumatoid arthritis (ERA) and early axial spondyloarthritis (ESpA) versus the general population. Methods Baseline data of 689 patients with ERA from the Etude et Suivi des Polyarthrites Indifférenciées Récentes (ESPOIR) cohort (age 48.2±12.1 years, symptoms duration 14.2±14.5 weeks) and 645 patients with ESpA from Devenir des Spondylarthropathies Indifférenciées Récentes (DESIR; age 32.8±8.4 years, axial symptoms duration 79.0±45.7 weeks) were analysed. Metabolic and cardiovascular diseases (CVD), infections and neoplasia were determined in each cohort. The prevalence (95% CI) of several comorbidities was compared with that in the French general population. For patients without CVD, the 10-year risk of developing CVD was calculated using the Framingham and SCORE equations. The heart age was calculated using the 2008 Framingham points system. Results 42% of patients with ERA and 20.3% of patients with ESpA had at least 1 comorbidity; the most common were arterial hypertension (AHT) and dyslipidaemia. AHT prevalence (95% CI) in ERA (18.2% (15.5% to 21.3%)), but not in ESpA (5.08% (3.57% to 7.14%)), was significantly increased (p<0.05) compared with the general population (7.58%). Prevalence of tuberculosis history was higher in ERA (4.7% (3.3% to 6.6%)), and ESpA (0.99% (0.4% to 2.3%)) than in the general population (0.02%; both p<0.05). No differences were observed in malignancies, coronary heart disease or diabetes. In ERA, among patients without a history of CVD, an intermediate to high CVD risk was found. The heart age exceeded the real age by 4.1±9.6 years in ERA and by 2.1±7.0 years in ESpA (p<0.001). Conclusions We found an increased prevalence of AHT and tuberculosis history in ERA and ESpA, and an increased CVD risk. These results should prompt rheumatologists to check these comorbidities early in the disease. PMID:26535145

    Our paper discusses results of research conducted in Southern Poland focusing on social attitudes towards floods - natural hazards frequently observed in Poland. Lately (e.g. 1997, 2001, 2010) several hundred thousand of people suffered from floods occurring in all examined communities. Presented analyses are based on questionnaire survey in which several criteria were used to select places for studies: objective degree of risk, prior experience of extreme events, size of community, strength of social bonds, social capital and quality of life. Nearly 2000 responses (from 9 communities) were gathered from the survey. Our main research questions were following: - are there differences between attitudes in those communities depending on how frequently they have experienced floods? - does settlement size have an impact on social attitudes towards floods, especially on mitigation behaviour? - are urban inhabitants less adapted to floods be upheld and do rural communities show more activity in the face of natural disasters? - what do information and education policies concerning floods look like? Three dimensions of social attitudes towards natural hazards were analyzed: cognitive (knowledge and awareness of local hazards), emotional (feelings towards hazards, like concern and anxiety); and instrumental (actions taken in response to a potential natural disaster). A combination of these three dimensions produces various types of perception and behaviour towards the perceived hazard (Raaijmakers et al., 2008): ignorance when the local population is unaware of a threat and therefore develops no concern and takes no preventive actions; safety when the local population is aware of a threat, but regards its level as either low or acceptable and is therefore not concerned with the threat and makes no preparations for a disaster; risk reduction when a high level of awareness and concern produces the mechanism of reducing the cognitive dissonance and denial of a disaster threat

    In Poland there are only Regional Bioethical Committees. Unlike most EU countries Poland has no coordinating centre on bioethics for human research. However, the Ministry of Health and Welfare has established a Bioethics Appeals Committee. The functioning of the Bioethical Committees in Poland is regulated in detail by the Regulation of the Ministry of Health and Welfare of 1999. All regulations comply with important guidelines such as: the Helsinki Declaration, The Rules of Good Clinical Practice, EU Directives and legal regulations binding in Poland, mainly the Act of the Medical Doctor Profession and the Dentist Profession, as well as the Act of Pharmaceutical Law. In the framework of the Human Biomonitoring Programme, the application for bioethical evaluation will be submitted to the Bioethical Committee at the Nofer Institute of Occupational Medicine in Lodz. The data protection legislation in Poland according to the Act of the Protection of Personal Data of 29th of August 1997 with latest amendments fulfils EU regulations. The Act also contains detailed provisions regarding the duties of the Inspector General for Data Protection. The paper presents data on the activities of the Bureau of the Inspector General for Personal Data Protection in 2005, 2006 and 2007. PMID:18541070

    The Lower Vistula Region in northern Poland is a stratotype area for the Vistulian (Weichselian) glaciation and during Last Glacial Maximum (LGM) the southernmost extension of the Scandinavian ice sheet occurred in western Poland and in eastern Germany. Reinterpretation of the available geochronological data (radiocarbon, 36Cl and 10Be ages), supplied with new field geological evidence, mostly for the Late Vistulian ice sheet limits and movement directions, was focused in three key regions in Poland. During the late Middle Vistulian there was one or two ice sheet advances in the Lower Vistula region. The Late Vistulian maximum ice sheet limit in Poland was time-transgressive and occurred at 24-19 kyrs BP (generally, the younger to the east). Ice sheet limits during the Leszno Phase occurred at 24 cal/10Be/36Cl kyrs, the Poznań Phase ice sheet limit was dated to 19 10Be/36Cl kyrs and the Pomeranian Phase ice sheet limit about 16-17 10Be/36Cl kyrs. Every Late Vistulian glacial phase in Poland was preceded by an ice sheet retreat.

    Infections with dengue virus are transmitted by mosquitoes. In tropical areas, it is mainly spread by Aedes aegypti while in countries with lower temperatures by Aedes albopictus. Since 2010, autochthonous cases of dengue are also reported in Europe. There are 4 serotypes of dengue virus (DENV). No correlation between clinical presentation of disease and virus type, however, were determined. Nevertheless, reinfection with different type of DENV may lead to a serious, life-threatening condition. An estimated 100 million persons are infected with dengue virus per year. Of them, approximately a half (mainly children) develop the symptoms of dengue fever (DF), dengue haemorrhagic fever (DHF) or dengue shock syndrome (DSS). Fatality is high in case of severe dengue. Dengue is a serious condition provided there is a presence of IgG antibodies directed against antigens of particular DENV serotypes, associated with primary infection caused by different serotype or transferred from infected mother to her child. For adequate dengue laboratory diagnosis, it is required to apply a set of various diagnostic methods. Within the family Flaviviridae, cross-reactivity is reported, which may lead to the occurrence of false-positive results. In Poland, differential diagnosis with different Flavivirus species is of special importance as it is an endemic area for tick-borne encephalitis (TBE). Thus, data regarding history of patient's immunization against TBE or yellow fever should be also taken into consideration as important in interpretation of results of serological examination.

    The Ner River valley (central Poland) underwent substantial transformation during the Weichselian-Holocene transition as a result of fluvial processes and climate changes, resulting in the establishment of its present shape in the Holocene. A multiproxy study based on organic deposits from a palaeochannel fill (Lutomiersk-Koziówki) shows that after the channel was cut off during the late glacial termination, it became a shallow oxbow, fed by local springs. In the Boreal period, the oxbow lake was also fed by precipitation and became a telmatic environment overgrown by rush and swamp vegetation. Finally, it was covered by overbank deposits. The first flooding phase (9900-9600 cal. BP) was followed by the accumulation of overbank sediments (after 9500 cal. BP) and flooding increased after ca. 9300-9000 cal. BP. Pollen data provide information on the regional vegetation context for local and regional changes. In the Atlantic period, an increase in both summer and winter temperatures is inferred from the pollen data, corresponding to an expansion of thermophilous deciduous forests. While in general, flooding phases of the Early Holocene are poorly recognised in Eastern Europe, the Lutomiersk-Koziówki site may be considered as one of the reference points for this phenomenon in the region.

    Background and Aims Chemoembolization is a standard treatment for hepatocellular carcinoma (HCC). Radioembolization with 90Y microspheres is a new, transarterial approach to radiation therapy. We performed a comparative effectiveness analysis of these therapies in patients with HCC. Methods We collected data from 463 patients who were treated with transarterial locoregional therapies (chemoembolization or radioembolization) over a 9-year period. We excluded patients who were not appropriate for comparison and analyzed data from 245 (122 who received chemoembolization and 123 who received radioembolization). Patients were followed for signs of toxicity; all underwent imaging analysis at baseline and follow-up timepoints. Overall survival was the primary outcome measure. Secondary outcomes included safety, response rate, and time-to-progression. Uni- and multi-variate analyses were performed. Results Abdominal pain and increased transaminase activity were more frequent following chemoembolization (P<.05). There was a trend that patients treated with radioembolization had a higher response rate than with chemoembolization (49% vs. 36%, P=0.104). Although time-to-progression was longer following radioembolization than chemoembolization (13.3 months vs 8.4 months, P=0.046), median survival times were not statistically different (17.4 months vs 20.5 months, P=0.232). Among patients with intermediate-stage disease, survival was similar between groups that received chemoembolization (17.5 months) and radioembolization (17.2 months, P=0.42). Conclusion Patients with HCC treated by chemoembolization or radioembolization with 90Y microspheres had similar survival times. Radioembolization resulted in longer time-to-progression and less toxicity than chemoembolization. Post-hoc analyses of sample size indicated that a randomized study with >1000 patients would be required to establish equivalence of survival times between patients given the different therapies.

    2013-01-01

    Background 'An ounce of prevention is worth a pound of cure’ is a common saying, and indeed, most health economic studies conclude that people are more willing to pay for preventive measures than for treatment activities. This may be because most health economic studies ask respondents to compare preventive measures with treatment, and thus prompt respondents to consider other uses of resources. However, psychological theorizing suggests that, when methods do not challenge subjects to consider other uses of resources, curative treatment is favored over prevention. Could it be that while prevention is praised, cure is preferred? Methods In two experimental studies, we investigated, from a psychological perspective and using a between-subjects design, whether prevention or treatment is preferred and why. In both studies, participants first read a lung cancer prevention or treatment intervention scenario that varied on the prevention-treatment dimension, but that were the same on factors like 'costs per saved life’ and kind of disease. Then participants completed a survey measuring appreciation (general and monetary) as well as a number of potential mediating variables. Results Both studies clearly demonstrated that, when the design was between-subjects, participants had greater (general and monetary) appreciation for treatment interventions than for preventive interventions with perceived urgency of the intervention quite consistently mediating this effect. Differences in appreciation of treatment over preventive treatment were shown to be .59 (Study 1) and .45 (Study 2) on a 5-point scale. Furthermore, participants thought that health insurance should compensate more for the treatment than for preventive measures, differences of 16% (Study 1), and 22% (Study 2). When participants were asked to directly compare both interventions on the basis of a short description, they preferred the preventive intervention. Conclusion It appears that people claim to prefer

    Research presents an overview on thunderstorm occurrence in Poland and focuses mainly on the relationship between human observations of thunderstorms (SYNOP daily summaries) and instrumental lightning detection data (PERUN network) in the timeframe between 2002 and 2013. The total of 4,952,203 cloud-to-ground flashes (2082 days with thunderstorms) derived from the PERUN lightning database, and 12,419 daily thunderstorm SYNOP reports from 44 meteorological stations (1417 days with thunderstorms) are compared. Within the use of two different computational methods, we define the threshold value of the human average observational thunderstorm detection range within a meteorological station. Results indicate that the average of this value ranges from 16.9 km (Delta computational method) to 18.3 km (threat score computational method). Given the limitations of both methods, we believe that the average of these two (17.5 km) may be the most reliable estimate that expresses how lightning is perceived by humans. Large differences in observational range values between some of the stations (e.g. from 12 km in Bielsko-Biała to 24 km in Łeba) indicate that thunderstorm measurements performed by humans are not homogeneous and are prone to errors. We estimate that an average increase/decrease of observational range by approximately 1 km results in 1 additional/redundant day in the average annual number of thunderstorm days in the climatological sense. Results indicate that already existing thunderstorm climatology papers that are based on SYNOP thunderstorm reports may present presumably not entirely reliable results and overestimate or underestimate values from the real distribution.

    Crystalline silica is an agent harmful to human health, and quite frequently present in occupational environments. Occupational groups exposed to crystalline silica dust include mostly workers of the mineral and coal mining as well as metallurgical, chemical and construction industries. In the European Union (EU), the number of those exposed to this agent is estimated at over 2 million persons. In Poland, the number of people employed under conditions of excessive silica dust exposure exceeds 50 thousand. The assessment of occupational exposure to crystalline silica comprises several steps: primarily workplace determinations, quantitative sample analyses and comparisons of the obtained results with admissible values. This work describes a set of instruments that enables direct comparison of the study results with admissible values binding in almost 40 countries. It also highlights the consequences resulting from the classification of quartz and cristobalite, the most common forms of crystalline silica, as carcinogens by the International Agency for Research on Cancer (IARC). A survey of air sampling and dust determination methods used in various countries to measure airborne dust concentrations of crystalline silica in occupational environments are presented along with relevant tables. The GESTIS data base, specifying the methods considered by EU as suitable for measuring and assessing harmful agents, was used as the selection criterion. Particular attention was paid to the methods used to determine crystalline silica; the effect of analytical methods applied, sample preparation procedures, and reference materials on the results of determinations was also analyzed. Main parameters of method validation, such as detection and determination limits, and precision of the analysis were compared. PMID:18041202

    This report describes the first identification in Poland of bovine viral diarrhoea virus (BVDV)-2 in a dairy herd where severe clinical disease with losses of young animals was observed. The virus was readily cultivated in cell culture and a phylogenetic analysis of the nucleotide sequences and secondary structures of the viral genomic 5' untranslated region confirmed virus identity. The economic impact of the infection was significant compared to the previously prevalent BVDV-1 infections confirming that this genotype of BVDV can cause severe sickness in affected herds. The use of BVDV-1 vaccine did not prevent the infection with the BVDV-2 genotype. PMID:25457262

    The aim of this study was to evaluate the level of lead (Pb) in the livers and kidneys of free-living animals from Poland, with regard to the differences in tissue Pb content between the species. The research material consisted of liver and kidney samples collected from roe deer (Capreolus capreolus), red deer (Cervus elaphus), and wild boar (Sus scrofa) that had been hunted in 16 voivodeships of Poland. The concentration of lead had been measured using inductively coupled plasma optical emission spectrometry (ICP-OES) method. The results show that differences in lead concentration in the organs depended on the geographic location. In roe deer and red deer, the highest mean lead concentrations in the livers and kidneys, observed in the central region of Poland, were twice as high as the lowest concentration of Pb in these animals from the northeastern region of the country. In wild boar, the highest mean concentration of Pb was noted in the livers of animals from the central region of Poland and in the kidneys of animals from the northwestern region, while the lowest lead concentrations in both organs were typical for wild boar from the southeast part of the country. Our results show that areas located in the center and in the north of Poland carry most of the burden of lead bioaccumulation. PMID:27068893

    Objectives To characterise the comparative effectiveness of combination therapy (a tumour necrosis factor inhibitor (TNFi) and a conventional synthetic disease-modifying antirheumatic drug (csDMARD) such as methotrexate) and monotherapy (TNFi only) for psoriatic arthritis (PsA) from a large US registry. Methods The analysis included adult patients with PsA who were enrolled in the Corrona database (ClinicalTrials.gov, NCT01402661), had initiated a TNFi, were biologic naïve, and had a follow-up visit ≥90 days after drug initiation. The endpoints of the analysis were TNFi persistence (drug survival) and time to Clinical Disease Activity Index (CDAI) remission. All analyses were performed using propensity scoring, which were estimated using CDAI and patient sex, to control for channelling bias. Results Of 519 patients meeting the inclusion criteria (318 with combination therapy and 201 with monotherapy), the analysis population was 497 for TNFi persistence and 380 for time to remission. The difference between combination therapy (TNFi+methotrexate, 91% of patients; TNFi+other csDMARD, 9%) and monotherapy was not statistically significant for TNFi persistence (32 and 31 months, p=0.73) and time to remission (21 and 25 months, p=0.56). Predictors of TNFi persistence included Hispanic ethnicity (longer persistence), PsA duration (longer persistence), history of methotrexate use (shorter persistence), body mass index (shorter persistence) and disease activity (shorter persistence). Conclusions Patients with PsA from a large US registry experienced similar TNFi persistence on combination therapy and monotherapy. Prospective, randomised clinical trials evaluating the efficacy of combination therapy versus monotherapy would provide much-needed clarity on treatment options for patients with PsA. Trial registration number NCT01402661. PMID:26819748

  6. A Study of The Eastern Mediterranean Hydrology and Circulation By Comparing Observation and High Resolution Numerical Model Results.

    Alhammoud, B.; Béranger, K.; Mortier, L.; Crépon, M.

    The Eastern Mediterranean hydrology and circulation are studied by comparing the results of a high resolution primitive equation model (described in dedicated session: Béranger et al.) with observations. The model has a horizontal grid mesh of 1/16o and 43 z-levels in the vertical. The model was initialized with the MODB5 climatology and has been forced during 11 years by the daily sea surface fluxes provided by the European Centre for Medium-range Weather Forecasts analysis in a perpetual year mode corresponding to the year March 1998-February 1999. At the end of the run, the numerical model is able to accurately reproduce the major water masses of the Eastern Mediterranean Basin (Levantine Surface Water, modi- fied Atlantic Water, Levantine Intermediate Water, and Eastern Mediterranean Deep Water). Comparisons with the POEM observations reveal good agreement. While the initial conditions of the model are somewhat different from POEM observations, dur- ing the last year of the simulation, we found that the water mass stratification matches that of the observations quite well in the seasonal mean. During the 11 years of simulation, the model drifts slightly in the layers below the thermocline. Nevertheless, many important physical processes were reproduced. One example is that the dispersal of Adriatic Deep Water into the Levantine Basin is rep- resented. In addition, convective activity located in the northern part of the Levantine Basin occurs in Spring as expected. The surface circulation is in agreement with in-situ and satellite observations. Some well known mesoscale features of the upper thermocline circulation are shown. Sea- sonal variability of transports through Sicily, Otranto and Cretan straits are inves- tigated as well.

    A review of the literature shows that origination of biological stones as well as their pathogenesis mostly depend on the environmental factors. As a result, the structural spectrum of such calculi and their chemical composition are highly diversified. It is well known that biological stones are formed mostly in the digestive and urinary tracts. However, it has been demonstrated that this kind of stony structure can be also, though rarely, found in circulatory and reproductive systems, skin, mucosa, and tear ducts. Although in palaeopathology, the list of biological stones is enriched by stony tumours and/or discharges, it is very difficult to uncover the small size deposits in excavation material. In the literature such findings, originating from different countries and centuries, are few. The described stone was found among the bones of an adult individual in the medieval cemetery of Gdańsk (Poland). The SEM, X-ray spectrometer and chemical evaluation revealed that it was a bladder calculus. PMID:25275551

  8. Genesis of transverse kame trains in eastern Poland

    2007-01-01

    Transverse kames, forming trains perpendicular to the direction of ice-sheet advance, are rare morphological elements in previously glaciated areas. The genesis of an example from the ice-contact zone of the Wartanian glaciation in eastern Poland is discussed. The transverse kames there form two main, distinctly separated, sub-parallel trains. Their sedimentary successions fill erosional troughs incised in the pre-Wartanian deposits on northern slopes. They consist of thick glaciofluvial sand and glaciofluvial/glaciolacustrine sandy/silty units that are covered with a thin, usually discontinuous, glacial till succession. The genesis of this kame type has been modelled. It is concluded that transverse kames developed in two phases: (1) erosion of the substratum in subglacial channels during initial deglaciation, and (2) glaciofluvial deposition in crevasses during advanced deglaciation (in the form of low-energy fans periodically submerged under stagnant water), followed locally by a cover of flowtills. Both the ablation of the ice and the accumulation of the kame deposits were controlled by the co-occurrence of ice zones either enriched or impoverished with sediment. Zonal enrichment of ice with debris was determined by the development of shear zones over substratum elevations that were inclined up-ice. The formation and subsequent infilling of crevasses both took place in zones of relatively clean ice, so that the resulting kames form a train perpendicular to the direction of ice movement.

  9. Defining HIV Risk and Determining Responsibility in Postsocialist Poland

    2014-01-01

    Drawing on 15 months of ethnographic research on HIV prevention programs in Poland, I explore the consequences of the shift from models of HIV prevention that emphasize “risk groups” and AIDS blame, to models that focus on “risky behaviors” and universal risk. The centrality of choice making and individual risk management in these models suggests objective risk assessment free from moralizing arguments. The Polish national prevention strategy shifted to focus on choice making, address all risk groups, and include concrete prevention strategies. This shift created a backlash that resulted in the reassertion of moral arguments about risk and risk groups that positioned those most vulnerable to HIV outside the purview of prevention efforts. AIDS organizations working with marginalized, “morally problematic” populations used the label “at risk” to legitimize claims to resources. They enacted a model of risk reduction in which the relevant actor is the individual buffeted by social forces, and behavior change, and therefore HIV risk reduction, is a long process because of myriad forms of vulnerability clients face. Despite efforts to reconceptualize risk, organizations positioned the individual as the locus of HIV prevention interventions, rather than attempting to address the social context that shapes risk.

    The aim of the paper was to discuss the problems related to the classification of B. subtilis and B. thuringiensis bacteria to the 2nd risk group under the 2005 decree of the Ministry of Health on hazardous biological agents (Law Gazette No. 81, item 716 with later amendments). The decree is a Polish implementation of the Directive 2000/54/EC generally consistent with its recommendations, but in the case of certain microorganisms a separate decision has been taken and having in mind the health of workers, changes in the list of hazardous agents existing in Poland have been made. The paper presents in detail the legal situation in this field, as well as current knowledge about the biology of these microorganisms, their use in the biotechnology industry and related production of allergenic proteins, and their effect on the human health. Placement ofB. subtilis and B. thuringiensis in the 2nd risk group resulted in the interpretative difficulties encountered by employers who use products containing these bacteria, institutions involved in such products trade and inspectorates supervising working conditions. Based on the literature review it is suggested to initiate actions leading to the development of hygiene norms for certain enzymes/bioinsecticides present in the air, the more that the tests to assess air concentrations of some of them are available. This solution would permit to remove B. subtilis and B. thuringiensis bacteria from the 2nd risk group without the risk for the care of workers' health. PMID:22774467

    Histomonosis (histomoniasis, blackhead), beside coccidiosis, belongs to the most important parasitic protozoan diseases in poultry. So far Histomonas meleagridis infections with varied mortality rates have been mainly diagnosed in young turkeys. Recently an increasing number of cases have been reported in chicken flocks in Europe resulting in economic losses. It is thought that this situation is predominantly caused by a complete withdrawal of the effective antihistomonals in the EU. Authors listed the selected outbreaks of histomonosis in 10 chicken flocks originated from different farms of 4 regions in Poland: 8 broiler breeder flocks (at mean age of 33 weeks) and 2 commercial layers flocks (at mean age of 38 weeks). This study reported here naturally occurring case of H.meleagridis infection in commercial broiler breeder (BB) flock line ROSS 308 at the age of 16 weeks. We showed acute form of infection with characteristic necrotic foci in the liver, and ulcerative typhilitis. Beside the liver and caeca, the multiple histomonads, lymphoid tissue depletion and heavy destruction in the bursa of Fabricius were observed. Additionally, the absence of systemic diffuse histomonads and lack of Heterakis gallinarum, caecal worm eggs in faecal samples were noted. PCR technique enabled to detect the presence of H.meleagridis genetic material in the investigated tissue samples. Authors indicate that histomonosis can be considered as re-emerging infectious diseases in chicken flocks of intensive production system. PMID:25976057

    Due to a lack of data in regard to the spread of viral infections in Polish pigeon populations, studies were undertaken to assess the frequency of adeno-, circo- and herpesvirus infections in flocks of pigeons across the entire country. In total, 107 flocks were examined, of which 61 per cent consisted of racing and 39 per cent of fancy pigeons. The flocks were divided into groups according to breed (racing and fancy pigeons) as well as physical condition (healthy and sick). In the studied pigeon flocks, the pigeon circovirus (PiCV) genetic material was the most frequently detected (44.5-100 per cent depending on the group), pigeon herpesvirus genetic material was second in frequency (0-30 per cent depending on the group), while genetic material of pigeon adenovirus was found only in two flocks of young birds with clinical symptoms of Young Pigeon Disease Syndrome (YPDS). The presence of fowl adenovirus (FAdV) genetic material was not detected in any of the studied flocks. Results obtained demonstrate a wide spread of circovirus in pigeon flocks in Poland, and substantiate earlier theories proposed by other authors, that immunosuppression evoked by PiCV infection is one of the main causative agents of YPDS.

    Transport is a major source of air pollution, noise, injuries and physical activity in the urban environment. The quantification of the health risks and benefits arising from these factors would provide useful information for the planning of cost-effective mitigation actions. In this study we quantified the burden of disease caused by local transport in the city of Warsaw, Poland. The disability-adjusted life-years (DALYs) were estimated for transport related air pollution (particulate matter (PM), nitrogen oxides (NOx), sulfur dioxide (SO2), benzo[a]pyrene (BaP), cadmium, lead and nickel), noise, injuries and physical activity. Exposure to these factors was based on local and international data, and the exposure-response functions (ERFs) were based on published reviews and recommendations. The uncertainties were quantified and propagated with the Monte Carlo method. Local transport generated air pollution, noise and injuries were estimated to cause approximately 58,000 DALYs in the study area. From this burden 44% was due to air pollution and 46% due to noise. Transport related physical activity was estimated to cause a health benefit of 17,000 DALYs. Main quantified uncertainties were related to disability weight for the annoyance (due to noise) and to the ERFs for fine particulate matter (PM2.5) air pollution and walking. The results indicate that the health burden of transport could be mitigated by reducing motorized transport, which causes air pollution and noise, and by encouraging walking and cycling in the study area.

    The paper gives the results of the first studies on the chemistry of cloud water collected during 3 mo (Aug.-Oct. 2010) in the free atmosphere over the area to the south of the Tri-City (Gdansk-Sopot-Gdynia) conurbation on the Gulf of Gdansk, Poland. Taken from cumulus, stratus, and stratocumulus clouds by means of an aircraft-mounted collector, the water samples were analyzed for the following contaminants: anions (chlorides, fluorides, nitrates, sulfates, and phosphates), cations (lithium, sodium, potassium, ammonium, calcium, and magnesium), and trace metals. In addition, pH values were measured, and the type and composition of suspended particulate matter was determined. We discuss the relationship between the concentration of inorganic ions and the type of cloud from which water was sampled. The chemistry is also likely related to the circulation pattern and inflow of clean air masses from the Baltic Sea. Moreover, a relationship was found between the composition of the samples examined and the location of pollutant emission sources. PMID:25602567

    Botanical gardens offer continuity for phenological recording in observers, protocols and plant specimens that may not be achievable from other sources. Here, we examine phenological change and synchrony from one such garden in western Poland. We analysed 66 botanical phenophases and 18 interphase intervals recorded between 1977 and 2007 from the Poznań Botanical Garden. These were examined for trends through time and responsiveness to temperature. Furthermore, we derived measures of synchrony for start of spring and end of autumn events to assess if these had changed over time. All 39 events with a mean date before mid-July demonstrated a significant negative relationship with temperature. Where autumn events were significantly related to temperature, they indicated a positive relationship. Typically, spring events showed an advance over time and autumn events a delay. Interphase intervals tended to lengthen over the study period. The measures of synchrony changed significantly over time suggesting less synchrony among spring events and also among autumn events. In combination, these results suggest increases in growing season length. However, responses to a changing climate were species-specific. Thus, the transitions from winter into spring and from autumn into winter are becoming less clearly defined.

    Between 1944 and 1989--the period of communist power in Poland--the national pharmaceutical market experienced several dramatic changes. The country was a prodigious importer of drugs following the Second World War, with a large portion of the medicine received being donated by various aid organisations. In the 1960s, Poland became a significant exporter of drugs to the Eastern Bloc countries, but dropped down the list of meaningful producers again after the post-1989 transformation. For four and a half decades the pharmaceutical market in Poland had been a scene of political and ideological struggle. The companies, owned and controlled by the state, were poorly managed, being neither innovative nor competitive. This fact, along with the state's irrational and inconsequent drug policy, caused an almost permanent shortage in drug supplies for patients: ironic for a socialist system in which universal and free health care was a basic principle.

    Poland syndrome is a rare congenital malformation. This syndrome was described in 1841 by Alfred Poland at Guy's Hospital in London. It is characterized by hypoplasia of the breast and nipple, subcutaneous tissue shortages, lack of the costosternal portion of the pectoralis major muscle and associated alterations of the fingers on the same side. Corrective treatment of the chest and soft tissue abnormalities in Poland syndrome varies according to different authors. We report the case of a 17-year-old adolescent who underwent chest wall reconstruction with a methyl methacrylate prosthesis. This surgical procedure is recommended for large anterior chest wall defects, and it prevents paradoxical movement. Moreover it provides for individual remodeling of the defect depending on the shape of the patient's chest. PMID:23453291

    Cryptosporidium intestinal parasites have been detected in farmed pigs worldwide. Infections are usually asymptomatic with a low number of oocysts shed in pig feces. This makes the recognition of infection difficult or unsuccessful when microscopic methods are used. The aim of this study was molecular identification of Cryptosporidium species in pig herds raised in Poland with regard to the occurrence of zoonotic species. In total, 166 pig fecal samples were tested. The examined pigs were aged 1 to 20 weeks. Overall, 39 pig farms were monitored for parasite presence. The detection and identification of Cryptosporidium DNA was performed on the basis of PCR-RFLP and nucleotide sequence analysis of the amplified 18 SSU rRNA and COWP gene fragments. Infected animals were housed in 21 (53.8%) of the pig farms monitored. The presence of Cryptosporidum was confirmed in 46 (27.7%) samples of pig feces. Among positive fecal samples, 34 (29.3%) were collected from healthy animals, and 12 (24%) from diarrheic pigs. Most infected animals (42.1%) were 2 to 3 months old. The following parasite species were detected: C. scrofarum, C. suis and C. parvum. Indeed, asymptomatic infections caused by C. scrofarum were observed in the majority of the herds. Mixed infections caused by C. suis and C. scrofarum were not common; however, they were observed in 8.6% of the positive animals. C. parvum DNA was found only in one sample collected from a diarrheic pig. The application of molecular diagnostic tools allowed for detection and identification of Cryptosporidium species in pigs. The sporadic findings of C. parvum are subsequent evidence for the contribution of pigs in the transmission of cryptosporidiosis from animals to humans. PMID:25638969

    Here, we present the first detected cases of bluetongue virus (BTV) in native cattle from Poland. The virus was found in animals located near the Polish-Belarusian and Polish-Lithuanian borders. The positive animals were detected through an official epidemiological surveillance program. A combination of type-specific real-time RT-PCR and phylogenetic tests revealed the presence of BTV serotype 14 (BTV-14). This serotype is highly homologous to the vaccine strain and BTV-14 present in Russia, Lithuania, and Spain (from an animal imported from Lithuania). The most probable route of virus introduction to Poland was transmission through midges. All of the cases were subclinical. PMID:27068167

    Like other Central European countries, Poland faces the twin challenges of improving environmental quality while also promoting economic development. The study examines the cost of achieving alternative emission standards and the savings in abatement cost that might be achieved with policies that rely on economic incentives rather than with rigid command and control measures. A central element of the analysis is a dynamic model of least-cost energy supply in Poland that allows examination at a national level of the effects of different pollution standards and policies.

This has changed the once predominant character of Poland as a ¿sending' migrant country into a ¿sending' and 'receiving' one. The extra burden of additional temporary or permanent migrants from neighboring East and Central European states is, together with the expanding number of asylum seekers, placing further strains on the country's economy. It also has changed the demographic structure of the nation-state as well as the social and economic (trade) structure and traffic patterns." (EXCERPT) PMID:12293076

    Neuropsychologists and other clinicians often comment on the minimal relationship that frequently exists between formal assessments of executive functions, analysis of findings, recommendations, and the person's real-life functioning. The authors' believe that current assessments of executive functions do not transfer easily to real-world behavior. There are limitations in the current examinations and in the settings in which they are given. The tests are artificial and the test settings lack the usual stresses, distractions, and multiple demands common to real life. The interactions are unlike what they experience in everyday life. The examiner often, but unintentionally orients the participant to relevant information that in turn can help the person compensate for the difficulties with executive control processes and bias the findings. We believe that virtual reality (VR) more closely approximates real life settings, the distractions, and the common interchanges (VR) provides a "life-like," three-dimensional (3-D) highly interactive environment, and safety from potential dangers that could arise in actual situations. VR can increase motivation because of its gaming, interactive, and immersive qualities and features are easily modified and allow for multiple applications. Our goal is to develop VR assessments that can be administered under controlled and safe conditions, but which are more sensitive to difficulties with executive control processes critical to safe, independent living. This initial study compares several functions assessed by the Wisconsin Card Sorting Test (WCST) with our three-dimensional, stereographic scenario, Look for a Match (LFAM) Study participants completed questionnaires, alternately began with either the WCST or LFAM, and then took the second test. All participants completed motion sickness and follow-up questionnaires. The results demonstrated that the study participants found LFAM to be more enjoyable and interesting, but found the

    A Europe-wide dynamic ammonia (NH3) emissions model has been applied for one of the large agricultural countries in Europe, and its sensitivity on the distribution of emissions among different agricultural functions was analyzed by comparing with observed ammonia concentrations and by implementing all scenarios in a chemical transport model (CTM). The results suggest that the dynamic emission model is most sensitive to emissions from animal manure, in particular how animal manure and its application on fields is connected to national regulations. To incorporate the national regulations, we obtained activity information on agricultural operations at the sub-national level for Poland, information about infrastructure on storages and current regulations on manure practice from Polish authorities. The information was implemented in the existing emission model and was connected directly with calculations from the Weather Research and Forecasting model (WRF). The model was used to calculate four emission scenarios with high spatial (5 km × 5 km) and temporal resolution (3 h) for the entire year 2010. In the four scenarios, we have compared a constant emission approach (FLAT), scenario (1) against (2) a dynamic approach based on the Europe-wide default settings (Skjøth et al., 2011, scenario DEFAULT); (3) a dynamic approach that takes into account Polish practice and less regulation compared to Denmark (POLREGUL); (4) a scenario that focuses on emissions from agricultural buildings (NOFERT). The ammonia emission was implemented into the chemical transport model FRAME (Fine Resolution Atmospheric Multi-pollutant Exchange) and modelled ammonia concentrations were compared with measurements. The results for an agricultural area suggest that the default setting in the dynamic model is an improvement compared to a non-dynamical emission profile. The results also show that further improvements can be obtained at a national scale by replacing the default information on manure

    This article presents the results of study about distribution, inflow and accumulation of polonium, uranium and plutonium in aquatic and land environment of Poland and the southern Baltic Sea. Radionuclides of (210)Po, (234)U and (238)U as well as (239+240)Pu and (241)Pu are strongly accumulated in Baltic organisms and plants and transferred through the trophic chain. The values of bioconcentration factor (BCF) in Baltic plants and animals are higher for polonium and plutonium in comparison with uranium. The principal source of radionuclides in the southern Baltic Sea is their inflow with rivers. Total annual runoff of polonium, uranium and plutonium from the Vistula and the Odra as well as the Pomeranian rivers were calculated at 95 GBq of (210)Po, 750 GBq of (234+238)U and 160 MBq of (238+239+240)Pu. Seasonal and spatial variability of (210)Po, (238)U and (239+240)Pu levels in the Vistula and the Odra drainage basins were assessed by application of neural-network based classification, especially cluster analysis (CA), principal component analysis (PCA) and self-organizing maps (SOM). The result for the Vistula river indicated correlation between polonium and plutonium as well as polonium and uranium. In the Odra drainage basin, the biggest differences were observed in the case of (238)U. To assess if there are statistically significant differences in mean concentration values of (210)Po, (238)U and (239+240)Pu for the Vistula and the Odra rivers drainage basins were obtained by used of the non-parametric tests. Comparing to the Vistula catchment area, statistically differences concentration of (210)Po and (239+240)Pu in all year was observed for river samples collected on the Odra drainage basin.

    The north-eastern part of Poland is considered an area of high risk for infection with tick-borne diseases, including with human granulocytic ehrlichiosis (HGE) agents. The etiological agent of HGE is Anaplasma phagocytophilum. As the animal reservoir for A. phagocytophilum in the environment serve the species from Cervidae and Bovidae families. European bison (Bison bonasus) and elk (Alces alces) are the big ruminant species, reintroduced to the forests of Middle Europe after many decades of absence. In the foci of zoonotic diseases they are able to play a role as natural reservoir to pathogens, however, their status as protected animals means their study has been rare and fragmentary. The studies of B. bonasus were conducted in Białowieża Primeval Forest and A. alces in Biebrza National Park. PCR amplifications were performed using primers amplifing the end of the groES gene, the intergenic spacer and approximately two-thirds of the groEL gene in the first round, and primers that span a 395-bp region of the groEL gene were used in the second round. The positive results were obtained in B. bonasus and A. alces, the prevalence of infection was 66.7 and 20.0%, respectively. Randomly selected samples were sequenced, sequences were compared with GenBank entries using Blast N2.2.13 and determined as A. phagocytophilum. The results presented herein are the first record of the presence of Anaplasma phagocytophilum in A. alces, and at the same time confirm the previous observations regarding the infection of B. bonasus with A. phagocytophilum.

    This two-part meta-analysis combined data from eight prospective randomized trials designed to compare the nutritional efficacy of early enteral (TEN) and parenteral (TPN) nutrition in high-risk surgical patients. The combined data gave sufficient patient numbers (TEN, n = 118; TPN, n = 112) to adequately address whether route of substrate delivery affected septic complication incidence. Phase I (dropouts excluded) meta-analysis confirmed data homogeneity across study sites, that TEN and TPN groups were comparable, and that significantly fewer TEN patients experienced septic complications (TEN, 18%; TPN, 35%; p = 0.01). Phase II meta-analysis, an intent-to-treat analysis (dropouts included), confirmed that fewer TEN patients developed septic complications. Further breakdown by patient type showed that all trauma and blunt trauma subgroups had the most significant reduction in septic complications when fed enterally. In conclusion, this meta-analysis attests to the feasibility of early postoperative TEN in high-risk surgical patients and that these patients have reduced septic morbidity rates compared with those administered TPN.

    The article concerns the most important demographic processes that took place in two post-communist countries, Poland and Ukraine, after 1990. These countries differ in terms of economic changes that they have gone through so far. In case of Poland we may consider it as a success in reforming the economy, despite the fact that it caused certain negative social phenomena, e.g. large unemployment. On the other hand, in Ukraine, economic crisis was not stopped, but it is also deepening and its results have become significant modifiers of population processes. The changes in population number, natural growth and migration in both countries are the subjects of detailed analyses. They were presented in the context of the "secondary demographic transition", which Poland and Ukraine entered rapidly at the beginning of 1990, along with economic transformation and social changes.

    This study aims to present the case of a female patient with Poland's syndrome and pectus excavatum deformity who underwent breast and chest wall reconstruction with a pre-shaped free deep inferior epigastric perforator flap. A 57-year-old female patient with Poland's syndrome and pectus excavatum presented with a Baker III capsular contracture following a previously performed implant-based right breast reconstruction. After a chest and abdominal CT angiography, she was staged as 2A1 chest wall deformity according to Park's classification and underwent implant removal and capsulectomy, followed by a pre-shaped free abdominal flap transfer, providing both breast reconstruction and chest wall deformity correction in a single stage operation. Post-operative course was uneventful, and the aesthetic result remains highly satisfactory 24 months after surgery. Deep inferior epigastric free flap represents an interesting reconstructive solution when treating Poland's syndrome female patients with chest wall and breast deformities. PMID:25991894

    Bryła, Paweł

    2016-10-01

    This paper aims to investigate selected aspects of organic food consumption in Poland. We conducted a survey in a representative sample of 1000 consumers. Polish consumers are convinced that organic food is more expensive, healthier, more environmentally friendly, more tasty and more authentic than conventional food. They believe its arouses more trust, has a better quality, is subject to more strict controls, and is produced in a more traditional way. According to Polish consumers, the most important characteristics of organic food are healthiness and high quality. The perceived authenticity of organic food depends on its natural taste, product quality, labelling, in particular having a European quality sign, as well as the retailer type and a separate exposition place in the points of purchase (merchandising). The critical barrier to the development of the organic food market in Poland is the high price, followed by an insufficient consumer awareness, low availability of organic products, short expiry dates and low visibility in the shop. The principal motives of organic food selection in Poland include: healthiness, ecological character of the product, food safety considerations, superior taste, and quality assurance. We identified the motives for and barriers to organic food consumption in Poland. PMID:27417333

    The aim of this study was to determine residual polychlorinated biphenyls (PCBs) and organochlorine pesticides in the adipose tissue of wild terrestrial mammals coming from the same area in northwest Poland and to compare the organochlorine content and profile between species. The study was performed on five mammalian species, including omnivores (badger, wild boar, raccoon dog) and herbivores (roe deer, red deer). The obtained results show that the levels of residues of most of the analyzed compounds were greater in omnivorous mammals than herbivorous mammals. We found differences in the pattern of accumulation of organochlorines. In the raccoon dog organochlorines accumulated in the following descending order: DDTs > PCBs > HCHs > endrin > dieldrin; in the badger, wild boar, and roe deer, the order was as follows: DDTs > HCHs > PCBs > endrin > dieldrin; and in red deer, the order was as follows: HCHs > DDTs > PCBs > endrin > dieldrin. PCB 153 was dominant in herbivores and in the wild boar, whereas in the raccoon dog it was lower than PCB 138 and in badger lower than PCB 180. These differences in the tested species may reflect differences in metabolic capacity and/or feeding habits and an uneven distribution of organochlorines in the area where the animals lived. Maximum residue levels (MRLs) were exceeded in single samples from animals whose meat and fat can be consumed by humans. The greatest number of cases where MRLs were exceeded was observed in the adipose tissue of the badger (HCHs, DDTs, endrin, non-dioxin-like PCBs) and the fewest in the adipose tissue of roe deer (only lindane).

    There is no doubt that museum collections provide a wide variety of information on ticks. The tick collection at the Natural History Department of the Museum of Upper Silesia in Bytom consists only of 37 specimens as the department is focused mainly on building collections of insects and birds. However, this does not mean that such collection cannot contribute to our knowledge about these arthropods. The most valuable results of studies on the museum's tick collection concerned Polish fauna. There are specimens of I. ricinus dating back as far as 1930-1948, which are the first known records of the presence of this tick in the Upper Silesia. Two specimens collected in copula in 1941 might be the earliest record of the mating behaviour of this species in Poland. The most important result was the detection of 2 cases of H. marginatum presence in Poland, which by far are the oldest documented cases of its presence in this country. PMID:27294652

    There have been few studies comparing substance use and misuse (SU&M) in different performing arts forms. Herein, we identified and compared SU&M in women studying an art (ballet, n = 21), a non-Olympic sport (dance sport, n = 25), and an Olympic sport (synchronized swimming, n = 23). The sample of variables comprised general, educational, and sport factors, as well as SU&M data, including consumption of opiates, cigarettes, alcohol, nutritional supplements, doping behaviors, and beliefs. Using the Kruskal-Wallis test, we found no significant differences between study groups in potential doping behaviors. Most of the examinees reported that they did not rely on physicians' and/or coaches' opinions regarding doping. Only sport dancers recognized their consumption of cannabis as a violation of anti-doping rules. Those more convinced that doping habits are present in their sport (or art) have a certain tendency toward doping usage. In conclusion, a strong anti-doping campaign within the studied arts is suggested, focusing on the health-related problems of SU&M. PMID:20795336

    The main goal of this project is to show the influence of a large linear source of air pollution on dew formation and chemistry. Dew sampling was performed during the growing season of 2009 at 3 sites near Wroclaw in SW Poland in the vicinity of A4 motorway which connects southern part of Poland with Germany and other EU countries. The road crosses in this part a rural landscape from WSW to ENE direction. The traffic is notoriously heavy, even at night, and lorries constitute about one third of vehicles. Two of the sampling sites were set in a distance of 30 meters from the motorway edge on the opposite sides (SE and NW) of the road to monitor dew efficiency and chemistry depending on wind direction. The third one was set 1.25 km to the NNW of the former pair to represent background rural conditions beyond the road influence. All three sites and the motorway are surrounded by vast arable grounds with intense agriculture activity. Three insulated plane radiative condensers, each 1 m2 in area, inclined at 15°, were installed at measurement sites. Two series of measurements were performed: the first in April lasted twenty days including several days without sampling, the second in September was continuous and lasted eleven days. Altogether there were nineteen dew or hoar frost sampling days, nine in April and ten in September. Basic meteorological data were gathered three times daily. Water yield of three condensers was compared to meteorological data and between each other. The research findings show that the most favorable weather conditions corresponding to high amounts of dew or hoar frost were characterized by synoptic scale warm air advection, high relative humidity, moderate wind speed i.e. 2-3 m/s and radiative weather. The samples from condenser located in calm air site usually had less volume than the other in windy place. The motorway heat source imposed a strong impact on efficiency of dew. The condenser on the leeward site of the road was characterized

    Immunizations are crucial to the prevention of disease, thus, having an accurate measure of vaccination status for a population is an important guide in targeting prevention efforts. In order to comprehensively assess the validity of self-reported adult vaccination status for the eight most common adult vaccines we conducted a survey of vaccination receipt and compared it to the electronic medical record (EMR), which was used as the criterion standard, in a population of community-dwelling patients in a large healthcare system. In addition, we assessed whether validity varied by demographic factors. The vaccines included: pneumococcal (PPSV), influenza (Flu), tetanus diphtheria (Td), tetanus diphtheria pertussis (Tdap), Human PapillomaVirus (HPV), hepatitis A (HepA), hepatitis B (HepB) and herpes zoster (shingles). Telephone surveys were conducted with 11,760 individuals, ≥ 18, half with documented receipt of vaccination and half without. We measured sensitivity, specificity, positive and negative predictive value, net bias and over- and under-reporting of vaccination. Variation was found across vaccines, however, sensitivity and specificity did not vary substantially by either age or race/ethnicity. Sensitivity ranged between 63% for HepA to over 90% (tetanus, HPV, shingles and Flu). Hispanics were 2.7 times more likely to claim receipt of vaccination compared to whites. For PPSV and Flu those 65+ had low specificity compared to patients of younger ages while those in the youngest age group had lowest specificity for HepA and HepB. In addition to racial/ethnic differences, over-reporting was more frequent in those retired and those with household income less than $75,000. Accurate information for vaccination surveillance is important to estimate progress toward vaccination coverage goals and ensure appropriate policy decisions and allocation of resources for public health. It was clear from our findings that EMR and self-report do not always agree. Finding

    To assess relationships of inflammatory markers and 2 related clinical factors with blood culture results, we retrospectively investigated inpatients' blood culture and blood chemistry findings that were recorded from January to December 2014 using electronic medical records and analyzed the data of 852 subjects (426 culture-positive and 426 culture-negative). Results suggested that the risk of positive blood culture statistically increased as inflammatory marker levels and the number of related factors increased. Concerning the effectiveness of inflammatory markers, when the outcome definition was also changed for C-reactive protein (CRP), the odds ratio had a similar value, whereas when the outcome definition of blood culture positivity was used for procalcitonin (PCT), the greatest effectiveness of that was detected. Therefore, the current results suggest that PCT is more useful than CRP as an auxiliary indication of bacterial infection. PMID:26525643

    Weather and climate are important natural resources for tourism and recreation, although sometimes they can make outdoor leisure activities less satisfying or even impossible. The aim of this work was to determine weather perception seasonal variability of people staying outdoors in urban environment for tourism and recreation, as well as to determine if personal factors influence estimation of recreationist actual biometeorological conditions and personal expectations towards weather elements. To investigate how human thermal sensations vary upon meteorological conditions typical for temperate climate, weather perception field researches were conducted in Warsaw (Poland) in all seasons. Urban recreationists' preference for slightly warm thermal conditions, sunny, windless and cloudless weather, were identified as well as PET values considered to be optimal for sightseeing were defined between 27.3 and 31.7 °C. The results confirmed existence of phenomena called alliesthesia, which manifested in divergent thermal perception of comparable biometeorological conditions in transitional seasons. The results suggest that recreationist thermal sensations differed from other interviewees' responses and were affected not only by physiological processes but they were also conditioned by psychological factors (i.e. attitude, expectations). Significant impact of respondents' place of origin and its climate on creating thermal sensations and preferences was observed.

  16. Mothers say "baby" and their newborns do not choose to listen: a behavioral preference study to compare with ERP results.

    Previously published results from neonatal brain evoked response potential (ERP) experiments revealed different brain responses to the single word "baby" depending on whether it was recorded by the mother or an unfamiliar female. These results are consistent with behavioral preference studies in which infants altered pacifier sucking to contingently activate recordings of the maternal vs. an unfamiliar female voice, but the speech samples were much longer and information-rich than in the ERP studies. Both types of neonatal voice recognition studies imply postnatal retention of prenatal learning. The preference studies require infant motor and motivation systems to mount a response in addition to voice recognition. The current contingent sucking preference study was designed to test neonatal motivation to alter behavior when the reward is the single word "baby" recorded by the mother or an unfamiliar speaker. Results showed an absent or weak contingent sucking response to the brief maternal voice sample, and they demonstrate the complementary value of electrophysiological and behavioral studies for very early development. Neonates can apparently recognize the maternal voice in brief recorded sample (previous ERP results) but they are not sufficiently motivated by it to alter sucking behavior. PMID:25859203

    While numerous ancient human DNA datasets from across Europe have been published till date, modern-day Poland in particular, remains uninvestigated. Besides application in the reconstruction of continent-wide human history, data from this region would also contribute towards our understanding of the history of the Slavs, whose origin is hypothesized to be in East or Central Europe. Here, we present the first population-scale ancient human DNA study from the region of modern-day Poland by establishing mitochondrial DNA profiles for 23 samples dated to 200 BC – 500 AD (Roman Iron Age) and for 20 samples dated to 1000–1400 AD (Medieval Age). Our results show that mitochondrial DNA sequences from both periods belong to haplogroups that are characteristic of contemporary West Eurasia. Haplotype sharing analysis indicates that majority of the ancient haplotypes are widespread in some modern Europeans, including Poles. Notably, the Roman Iron Age samples share more rare haplotypes with Central and Northeast Europeans, whereas the Medieval Age samples share more rare haplotypes with East-Central and South-East Europeans, primarily Slavic populations. Our data demonstrates genetic continuity of certain matrilineages (H5a1 and N1a1a2) in the area of present-day Poland from at least the Roman Iron Age until present. As such, the maternal gene pool of present-day Poles, Czechs and Slovaks, categorized as Western Slavs, is likely to have descended from inhabitants of East-Central Europe during the Roman Iron Age.

    Global Navigation Satellite Systems (GNSS) are designed for positioning, navigation and amongst other possible applications it can also be used to derive information about the state of the atmosphere. Continuous observations from GNSS receivers provide an excellent tool for studying the neutral atmosphere, currently in near real-time. The Near Real-Time (NRT) neutral atmosphere and water vapour distribution models are currently obtained with high resolution from Ground Base Augmentation Systems (GBAS), where reference stations are equipped with GNSS and meteorological sensors. The Poland territory is covered by dense network of GNSS stations in the frame of GBAS system called ASG-EUPOS (www.asgeupos.pl). This system was established in year 2008 by the Head Office of Geodesy and Cartography in the frame of the EUPOS project (www.eupos.org) for providing positioning services. The GNSS data are available from 130 reference stations located in Poland and neighbour countries. The ground meteorological observations in the area of Poland and neighbour countries are available from ASG-EUPOS stations included in EUREF Permanent Network (EPN) stations, airports meteorological stations (METAR messages stations), and stations managed by national Institute of Meteorology and Water Management (SYNOP messages stations). Institute of Geodesy and Geoinformatics (IGG) of Wroclaw University of Environmental and Life Sciences had created permanent NRT service of ZTD (Zenith Total Delay) estimation for the area of Poland from GPS observations called IGGHZG. The first part of the paper presents the methodology of NRT GNSS data processing for ASG-EUPOS stations for ZTD estimation and its comparison to the results coming from EPN ACs and Military University of Technology in Warsaw AC (MUT AC).

    Cognitive abilities likely evolved in response to specific environmental and social challenges and are therefore expected to be specialized for the life history of each species. Specialized cognitive abilities may be most readily engaged under conditions that approximate the natural environment of the species being studied. While naturalistic environments might therefore have advantages over laboratory settings for cognitive research, it is difficult to conduct certain types of cognitive tests in these settings. We implemented methods for automated cognitive testing of monkeys (Macaca mulatta) in large social groups (Field station) and compared the performance to that of laboratory-housed monkeys (Laboratory). The Field station animals shared access to four touch-screen computers in a large naturalistic social group. Each Field station subject had an RFID chip implanted in each arm for computerized identification and individualized assignment of cognitive tests. The Laboratory group was housed and tested in a typical laboratory setting, with individual access to testing computers in their home cages. Monkeys in both groups voluntarily participated at their own pace for food rewards. We evaluated performance in two visual psychophysics tests, a perceptual classification test, a transitive inference test, and a delayed matching-to-sample memory test. Despite the differences in housing, social environment, age, and sex, monkeys in the two groups performed similarly in all tests. Semi-free ranging monkeys living in complex social environments are therefore viable subjects for cognitive testing designed to take advantage of the unique affordances of naturalistic testing environments.

    In 2005 and 2006, hydrogeochemical study was carried out in the bipartite Wiśniówka Mała pit lake of the Holy Cross Mountains (south-central Poland). This is the largest acidic water body in Poland. This report presents the element concentrations in the water and sediment, stable sulfur and oxygen isotope ratios in the soluble sulfates, and stable oxygen isotope ratio in the water. The scope of the investigation also encompassed mineralogical examinations (scanning electron microscope, X-ray diffraction) of the sediment. The results of this study show that there is a spatial and temporal variability in concentrations of most elements and sulfur isotope ratios in the examined pit lake. The water of the western pond displayed a lower pH with a mean of 3.73 and higher conductivity (390 μS cm-1) as well as higher concentrations of sulfates (156 mg L-1) and most of the cations and anions. The concentrations of Fe2+ and Fe3+ averaged 0.8 and 0.4 mg·L-1. In contrast, the eastern pond water revealed a higher pH (mean of 4.36), lower conductivity (293 μS cm-1) and lower sulfate (90 mg L-1) and trace metal levels. Similar variations were recorded in the stable sulfur isotope ratios. The δ34SV-CDT(SO4 2-) values in the water of the western pit pond were in the range of -6.7 to -4.6‰ (mean of -5.6‰), whereas that in the eastern pit pond ranged from -2.2 to -0.9‰ (-1.6‰). The alkalinity of the entire lake water was below 0.1 mg·L-1 CaCO3. No distinct difference in the δ18OV-SMOW(SO4 2-) was noted between the western and eastern pit ponds. Compared to the Purple Pond in the Sudetes (Poland) and similar sites throughout the world, the examined pit lake is highlighted by distinctly low concentrations of sulfates, iron and other trace metals. Based on this and other studies performed in the Holy Cross Mountains, a conclusion can be drawn that the SO4 2- in the Wiśniówka Mała pit lake water is a mixture of SO4 2- derived from the following sources: (1) pyrite

    ABSTRACT Objective To determine the efficacy of stress urinary incontinence treatments adding pelvic floor muscle training to vaginal electrical stimulation. Methods Forty-eight women with stress urinary incontinence were randomized into 2 groups: 24 underwent isolated vaginal electrical stimulation, and 24 vaginal electrical stimulation plus pelvic floor muscle training. History, physical examination, voiding diary, perineum strength test, and urodynamic study were assessed. Comparisons were made for adherence to treatment, muscle strength improvement, urinary symptoms, and degree of satisfaction immediately, 12 and 96 months after treatment. Results Patients' degree of satisfaction on vaginal electrical stimulation, and on vaginal electrical stimulation plus pelvic floor muscle training immediately, 12 and 96 months post treatment, were, respectively: 88.2% versus 88.9% 64.7% versus 61.1% and 42.9% versus 28.6% (p>0.05). Conclusion Vaginal electrical stimulation associated to pelvic floor muscle training did not show better results than vaginal electrical stimulation alone. PMID:25003921

    In this work the possibility of modeling manufacturing ceramic products is analyzed through the application of transient thermography, holographic interferometry and digital speckle photography, in order to identify the subsurface defects characteristics. This integrated method could be used to understand the nature of heterogeneous materials (such as plastic, sponge simulating a void, wood, aluminum) potentially contained within ceramic materials, as well as to predict crack formation due to them. The paper presents the analysis of green ceramic tile containing defects of different types and sizes located at different depths. The finite element method is used for solving the problem of transient heat transfer occurring in experimental conditions. Unknown parameters of the numerical model (such as convective heat transfer coefficients and sample surface emissivity) were adjusted to obtain numerical simulation results as close as possible to those obtained experimentally. Similarities and differences between experimental and simulated data are analyzed and discussed. Possibilities for improving the results and further developments are proposed.

    Regular air temperatures' changes, as an effect of succession of the seasons, are a part of people's everyday life. When winters and summers are not characterised by extreme thermal conditions, people are well prepared and there are no losses for agriculture and economy or human health consequences observed. A similar situation takes place in case of typical springs and autumns, where normally no too low or too high air temperatures occur. The situation becomes totally different when the air temperature significantly exceeds frames of typical temperature for particular months or seasons. Appearance of winter conditions during months in which they are not expected may lead to losses in different branches of the economy e.g. transport or agriculture. Heat in non-summer months potentially brings less damages for the economy, but it might be a great threat for human health, especially for those with cardiological diseases, and it may result in thermal discomfort. If these conditions last for sufficient period of time, they may cause disorders in plant vegetation cycles. One element of the discussion held on the global warming which has been observed since the half of the twentieth century, is the question of how this effects the occurrence of climatic anomalies. Does it result in an decrease of "cold" thermal anomalies and in an increase of frequency of "hot" anomalies? Or does it increase the occurrence of both types of these events? In this research there will be performed an analysis of the occurrence of conditions typical for winter months, outside the climatic winter (December, January, February) at ten locations in the area of Poland. During the months directly close to this period (November and March) the threshold for winter conditions will be maximum temperature below 0 oC which means occurrence of frost all day long. For other non-summer months the threshold will be mean daily temperature below 0 oC meaning low temperatures during the day, not only morning

  4. Model Related Estimates of time dependent quantiles of peak flows - case study for selected catchments in Poland

    Under Polish climate conditions the series of Annual Maxima (AM) flows are usually a mixture of peak flows of thaw- and rainfall- originated floods. The northern, lowland regions are dominated by snowmelt floods whilst in mountainous regions the proportion of rainfall floods is predominant. In many stations the majority of AM can be of snowmelt origin, but the greatest peak flows come from rainfall floods or vice versa. In a warming climate, precipitation is less likely to occur as snowfall. A shift from a snow- towards a rain-dominated regime results in a decreasing trend in mean and standard deviations of winter peak flows whilst rainfall floods do not exhibit any trace of non-stationarity. That is why a simple form of trends (i.e. linear trends) are more difficult to identify in AM time-series than in Seasonal Maxima (SM), usually winter season time-series. Hence it is recommended to analyse trends in SM, where a trend in standard deviation strongly influences the time -dependent upper quantiles. The uncertainty associated with the extrapolation of the trend makes it necessary to apply a relationship for trend which has time derivative tending to zero, e.g. we can assume a new climate equilibrium epoch approaching, or a time horizon is limited by the validity of the trend model. For both winter and summer SM time series, at least three distributions functions with trend model in the location, scale and shape parameters are estimated by means of the GAMLSS package using the ML-techniques. The resulting trend estimates in mean and standard deviation are mutually compared to the observed trends. Then, using AIC measures as weights, a multi-model distribution is constructed for each of two seasons separately. Further, assuming a mutual independence of the seasonal maxima, an AM model with time-dependent parameters can be obtained. The use of a multi-model approach can alleviate the effects of different and often contradictory trends obtained by using and identifying

  5. High resolution operational air quality forecast for Poland and Central Europe with the GEM-AQ model - EcoForecast System

    2013-04-01

    The air quality forecast is an important component of the environmental assessment system. The "Clean Air for Europe" (CAFE) Directive 2008/50/EC stipulates a need for numerical modelling in order to support public information services to interpret measurements of pollutants concentrations and to prepare and evaluate air quality plans. Most European countries have developed model-based air quality modelling and information services. We will present the design strategy, development and implementation of a regional high resolution forecasting system that was implemented in Poland. The new national high resolution air quality forecasting system has evolved from a semi-operational chemical weather system EcoForecast.EU which is based on the GEM-AQ model (Kaminski et al., 2008). GEM-AQ is a comprehensive chemical weather model where air quality processes (chemistry and aerosols), troposphere and stratospheric chemistry are implemented on-line in the operational weather prediction model, the Global Environmental Multiscale (GEM) model (Cote et al, 1998), developed at Environment Canada. For these applications, the model is run on a global variable resolution grid with horizontal spacing of 15 km over Europe. In the vertical there are 28 hybrid levels, with the top at 10 hPa. A high resolution nested forecast at 5 km resolution over Poland (and surrounding countries) was implemented in December 2012. The forecast is published once a day at www.EcoForecast.EU. The air quality forecast is presented for ozone, nitrogen dioxide, sulphur dioxide, carbon monoxide, PM10 and PM2.5 as maps of daily maxima and daily averages. We will present results from the on-going model evaluation study over Central Europe (2010-2012). Modelling results were evaluated and compared with available observation of ozone and primary pollutants from air quality monitoring stations and from meteorological synoptic stations. Ozone exposure indices, as defined in the CAFE Directive, will be shown for the

    Comparison of immediate postoperative results of patients undergoing cemented total knee arthroplasty with and without ischemia. Observational, cross-sectional, retrospective, analytical, single-center study that included 180 patients who underwent total knee arthroplasty from 2011 to 2014: 120 without ischemia, 60 with ischemia. Mean age was 70 years with SD ± 7. Criteria to assess the immediate postoperative results include intraoperative bleeding, hemoglobin differential and pain. Exclusion criteria comprised patients being treated at a pain clinic, those on anticoagulants, with a history of bleeding disorders, psychiatric conditions, kidney failure or those intolerant to NSAIDs. In total knee arthroplasty without ischemia there is better pain control (p = 0.026). The hemoglobin differential and intraoperative bleeding were less with ischemia (p = 0.008). 32.8% of patients required blood transfusion, but no statistically significant relationship was established with the use or non-use of ischemia (p = 0.301). The most commonly reported pain was within a VAS of 0-3; 62.2% of cases reported mild pain. Mean hemoglobin differential was 3.7 with SD ± 1.3 with a range from 0 to 7.4. Patients in whom no ischemia was used during the surgical procedure experienced less pain. There was less bleeding and hemoglobin differential with the use of ischemia. However, this did not result in a statistically significant difference in the need for blood transfusion. The use of ischemia with caution and according to the surgeons preference is recommended.

    Blood donor screening of viral markers in Poland is based on serologic testing for anti-HCV, HBsAg, anti-HIV1/2 (chemiluminescence tests) and on nucleic acid testing (NAT) for RNA HCV, RNA HIV-1 and DNA HBV performed in minipools of 6 with real-time PCR (MPX 2.0 test on cobas s201) or with TMA in individual donations (Ultrio Plus or Ultrio Elite). Donors of plasma for anti-D and anti-HBs production are tested for parvovirus B19 DNA. Before implementation tests and equipment are evaluated at the Institute of Hematology and Transfusion Medicine (IHTM). The last 20 years witnessed a decreasing trend for HBsAg in both first time and repeat donors (1%-0.3% and 0.1%-0.02% respectively). Prevalence of anti-HCV repeat reactive results was stable and oscillated around 0.8% for first time donors and 0.2% for repeat donors. Elevated prevalence of seropositive HIV infected donors was recently observed (7.5-9 cases/100,000 donors). Since respective molecular markers implementation HCV RNA was detected on average in 1/119,235 seronegative donations, HIV RNA in 1/783,821 and HBV DNA in 1/61,047. HBV NAT yields were mostly occult hepatitis B (1/80,248); window period cases were less frequent (1/255,146). The efficiency of HBV DNA detection depends on the sensitivity of the HBV DNA screening system. PMID:26519842

    Patient rights are the specification of general human rights. The rights define the patient position in relation to health institutions or medical professions providing, broadly understood, health services. The protection system of patient rights outlined by international legal and ethical regulations is detailed to specific social, political and economic realities by internal legal systems of individual states. Imperfections of the Polish health care system in relation to achieving adequate protection of patient rights, resulting, inter alia, from the lack of comprehensive regulation of the matter of patient rights, led the legislature to introduce new regulations concerning this aspect to the Polish legal order. The new Act of 6 November 2008 on Patient Rights and the Patient Rights Ombudsman (binding from 5 March 2009) is the first universally binding legal act in the Polish legal system entirely dealing with the matter of patient rights. It regulates the rights of the patient and correlated with them obligations of health care providers (public and non-public) irrespectively of both the legal form providers, as well as the sources of funding of the benefits provided. In particular, the Act states: the patient right to health services, right to obtain information, right to confidentiality of patient-linked information, right to consent to obtain health services, right to respect privacy and dignity of the patients, right to medical records and objecting to the doctor's opinion or decision, right to respect private and family life, right to pastoral care. The new regulations--besides the specification of the catalogue of patient rights--reinforced the institutional protection of patient rights by establishing a new central public administrative body having jurisdiction to protect patient rights--the Patient Rights Ombudsman. Poland, like other European countries, makes an attempt to improve the protection of patient rights. The introduction of the Act entirely

  9. Comparing the cognitive differences resulting from modeling instruction: Using computer microworld and physical object instruction to model real world problems

    NASA Astrophysics Data System (ADS)

    Oursland, Mark David

    This study compared the modeling achievement of students receiving mathematical modeling instruction using the computer microworld, Interactive Physics, and students receiving instruction using physical objects. Modeling instruction included activities where students applied the (a) linear model to a variety of situations, (b) linear model to two-rate situations with a constant rate, (c) quadratic model to familiar geometric figures. Both quantitative and qualitative methods were used to analyze achievement differences between students (a) receiving different methods of modeling instruction, (b) with different levels of beginning modeling ability, or (c) with different levels of computer literacy. Student achievement was analyzed quantitatively through a three-factor analysis of variance where modeling instruction, beginning modeling ability, and computer literacy were used as the three independent factors. The SOLO (Structure of the Observed Learning Outcome) assessment framework was used to design written modeling assessment instruments to measure the students' modeling achievement. The same three independent factors were used to collect and analyze the interviews and observations of student behaviors. Both methods of modeling instruction used the data analysis approach to mathematical modeling. The instructional lessons presented problem situations where students were asked to collect data, analyze the data, write a symbolic mathematical equation, and use equation to solve the problem. The researcher recommends the following practice for modeling instruction based on the conclusions of this study. A variety of activities with a common structure are needed to make explicit the modeling process of applying a standard mathematical model. The modeling process is influenced strongly by prior knowledge of the problem context and previous modeling experiences. The conclusions of this study imply that knowledge of the properties about squares improved the students

    The locations of H atoms in biological structures can be difficult to determine using X-ray diffraction methods. Neutron diffraction offers a relatively greater scattering magnitude from H and D atoms. Here, 1.65 {angstrom} resolution neutron diffraction studies of fully perdeuterated and selectively CH{sub 3}-protonated perdeuterated crystals of Pyrococcus furiosus rubredoxin (D-rubredoxin and HD-rubredoxin, respectively) at room temperature (RT) are described, as well as 1.1 {angstrom} resolution X-ray diffraction studies of the same protein at both RT and 100 K. The two techniques are quantitatively compared in terms of their power to directly provide atomic positions for D atoms and analyze the role played by atomic thermal motion by computing the {sigma} level at the D-atom coordinate in simulated-annealing composite D-OMIT maps. It is shown that 1.65 {angstrom} resolution RT neutron data for perdeuterated rubredoxin are {approx}8 times more likely overall to provide high-confidence positions for D atoms than 1.1 {angstrom} resolution X-ray data at 100 K or RT. At or above the 1.0{sigma} level, the joint X-ray/neutron (XN) structures define 342/378 (90%) and 291/365 (80%) of the D-atom positions for D-rubredoxin and HD-rubredoxin, respectively. The X-ray-only 1.1 {angstrom} resolution 100 K structures determine only 19/388 (5%) and 8/388 (2%) of the D-atom positions above the 1.0{sigma} level for D-rubredoxin and HD-rubredoxin, respectively. Furthermore, the improved model obtained from joint XN refinement yielded improved electron-density maps, permitting the location of more D atoms than electron-density maps from models refined against X-ray data only.

    Between 1995 and 2003 the Galileo spacecraft orbited Jupiter and flew-by multiple times at the Galilean satellites Io (7), Europa (12), Ganymede (5), and Callisto (8). The wealth of new unprecedented data from Galileo in-situ measurements in comparison to hybrid- and MHD simulation results enhanced our view of the understanding of the interaction between the moons (or in the case of Ganymede's own magnetosphere) and the surrounding highly dynamic Jovian magnetosphere. In this paper the in-situ particles and fields measurements are reviewed in the context of the future ESA-mission JUICE to arrive in the Jovian system in 2030.

    The objective of this study was to evaluate the contamination of vegetables, fruits and soil with zoonotic parasite eggs on organic and conventional farms in south-eastern Poland. To evaluate the contamination with eggs of zoonotic parasites, examinations were conducted on 8 conventional and 11 organic farms in south-eastern Poland from May-October in 2008 and 2009. The following fruit and vegetables were selected for the experiment: strawberry, leek, onion, carrot, zucchini, beetroot, parsley, potatoes, celery, rhubarb, lettuce, cabbage, broccoli, pumpkin, young beetroot leaves, cauliflower, French beans, turnip, fennel and sorrel. A total of 187 samples of vegetables, fruits and soil were examined by means of a modified flotation method according to Quinn et al. (1980). Contamination with Ascaris, Trichuris and Toxocara eggs was found, with a higher number of positive samples revealed on conventional (34.7%), compared to organic farms (18.9%). The level of contamination in soil samples from conventional farms was higher (88.5% positive samples), than of those from organic farms (32.8%). Of the 15 geohelmints eggs, positive samples were found in vegetables: 9 Toxocara eggs, 4 Ascaris eggs and 2 Trichuris eggs. No geohelmints eggs were observed in the strawberry samples. The consumption of vegetables and fruits contaminated with the eggs of parasites may be the cause of parasitoses in humans. Stricter sanitary standards on farms of all types may limit the incidence of parasitic zoonoses. PMID:23020033

    During the last two millennia human activity and their settlements together with varying climate conditions strongly influenced landscape scale changes. Especially within palaeoecological records these environmental responses are well expressed. However, a robust age control is needed for the evaluation and interpretation of biotic proxies.We present a record from the annually laminated (varved) sediments of Lake Czechowskie, located in northern Poland. The investigated record covers the past 2000 years and demonstrates the continuous vegetation history and human activity in the Northern part of the Tuchola Pinewoods. The chronology was established by varve counting and confirmed by AMS 14C dating, 137Cs activity measurement and a tephra layer (Askja 1875). We used high-resolution biotic (pollen, green algae and diatom analysis) sedimentological (varve and sublayer thickness variations) and geochemical (µ-XRF data) proxies to reconstruct the environmental changes within a time of increasing human activity and fluctuating climatic conditions. Based on different spatial sampling and measuring increments the temporal resolution varies between subseasonal (µ-XRF), annual (varves) up to five-varveresolution (biotic proxies) making it possible to trace even short lasting local and regional changes. Our results display visible human pressure in this area between 50- 350 yr. AD (Roman Period) exerted by tribes related to the Wielbark Culture. The development of persisting settlements and agriculture took place at expense of surrounding hornbeam forests. An intensification of lake productivity (expressed as an increase of varve thickness) started after 250 AD. If this lake ecosystem response relates to an intensified agriculture (and a possible transport of nutrients from neighboring rural lands) or to a climate shift will be further discussed. The rapid decline of human indicators about 350 years AD at the transition to the migration period might be related to cooler

    Climate change is a complex environmental problem that can be used to examine students' understanding, gained through classroom communication, of climate change and its interactions. The present study examines a series of four science sessions given to a group of primary school student teachers (n = 20). This includes analysis of the communication styles used and the students' pre- and post-conceptualisation of climate change based on results obtained via essay writing and drawings. The essays and drawings concerned the students' unprompted pre- and post-conceptions about climate change, collected before and after each of the four inquiry-based science sessions (in physics, chemistry, biology and geography). Concept mapping was used in the analysis of the students' responses. The communication used in the four sessions was analysed with a communicative approach in order to find out the discussion about climate change between teacher and students. The analyses indicated that the students did not have the knowledge or the courage to participate in discussion, but post-conceptualisation map showed that students' thinking had become more coherent after the four sessions. Given the results of the present study, proposals for using concepts maps and/or communication analysis in studying students' conceptions are presented.

    The Tajo Basin and Betic Mountain Chain in the south central region of the Iberian Peninsula were chosen for investigation in the first phase of the magnetotelluric (MT) component of the PICASSO (Program to Investigate the Convective Alboran Sea System Overturn) project. The MT results provide information about the electrical conductivity distribution in previously unprobed subsurface regions, as well as complimenting and enhancing results of prior geological and geophysical investigations thereby enabling the definition of a petrological subsurface model and a comprehensive understanding about the tectonic setting. Two-dimensional (2-D) inversion of the MT data provides enhanced insight into Iberian subsurface geology in the crust. The most striking features of the final model are (i) a distinct vertical interface within the Variscan basement beneath the center of the Tajo Basin that is spatially associated with the boundary between regions with and without substantial Alpine deformation, and (ii) a middle to lower crustal conductive anomaly that can be related to remnants of asthenospheric intrusion in connection with Pliocene volcanic events in the Calatrava Volcanic Province. For the latter, effects of hydrous phases are inferred that may originate from dehydration processes within the subducting slab beneath Alboran Domain and Betic Mountain Chain.

    Multidrug-resistant tuberculosis (MDR-TB) poses a serious challenge to the global control of the disease. The purpose of this study was to characterize MDR-TB patients from Poland and to determine the extent of MDR-TB disease attributable to recent transmission. The study included all 46 patients diagnosed with MDR-TB in Poland in 2004 and followed up for 6 years (until 2011). For each patient, sociodemographic and clinical characteristics, treatment outcomes, and bacteriological data were collected by the review of medical and laboratory records. Mycobacterium tuberculosis isolates from all patients were characterized using spoligotyping, mycobacterial interspersed repetitive unit-variable number tandem repeat (MIRU-VNTR) typing, IS6110 restriction fragment length polymorphism (RFLP) analysis, and sequencing analysis of drug resistance-associated loci (katG, mabA-inhA, rpoβ, rpsL, and embB). The majority of patients were male (86.9%), 40-64 years of age (60.8%), with a history of TB treatment (84.8%), and producing smear-positive sputa (86.9%). Twenty-two (47.8%) patients suffered from concomitant diseases and 28 (60.8%) were alcohol abusers. Treatment outcome assessment revealed that 8 (17.4%) patients were cured or completed therapy, while 15 (32.6%) died of TB, 11 (23.9%) defaulted, 8 (17.4%) failed, and 1 (2.2%) was transferred and lost to follow-up. Upon genotyping, 10 (21.7%) isolates were allocated in four clusters. These were further subdivided by mutational profiling. Overall, in 6 (13%) patients, MDR-TB was a result of recent transmission. For 4 (8.7%) of these patients, a direct epidemiological link was established. The study shows that the transmission of MDR-TB occurs at a low rate in Poland. Of urgent need is the implementation of a policy of enforced treatment of MDR-TB patients in Poland. PMID:25037868

    This prospective study investigated revision after modular short stem implantation. Results are presented for 2 different types of neck adapters (titanium and cobalt-chromium [CoCr]). Eighty-five patients with titanium adapters and 87 patients with CoCr adapters underwent follow-up examination after an average of 5.7 and 5.2 years, respectively. Mean patient age was 57 years in both groups. Indications were primary osteoarthritis (80%), cup dysplasia (14%), and other (6%). Mean Harris Hip Scores were 98 and 99 points (titanium and CoCr groups, respectively). Ninety percent and 96% of patients were very satisfied or satisfied (titanium and CoCr groups, respectively); 3% of patients in both groups were dissatisfied. Pain decreased from visual analog scale score 7 and 6 preoperatively to 0.37 and 0.15 postoperatively for the titanium and CoCr groups, respectively. No joint dislocation occurred. Six patients needed revision within the first year (2 for infection, 1 for via falsa position, and 2 for aseptic loosening in the titanium group, and 1 for aseptic loosening in the CoCr group). Nine revisions occurred due to neck adapter failure (titanium group). Primary standard stems were used in all revisions. Excluding material-related adapter failures in the titanium group, the 5-year survival rate was 94.8% (95% confidence interval [CI], 88.9-97.6 for titanium) and 99% (95% CI, 93.7-99.8 for CoCr). No radiographic signs of loosening were seen at last follow-up. Fine sclerotic lines were detected in Gruen zones 1 (17.2%) and 2 (14%), hypertrophies in zone 3 (4.3%), and periprosthetic cancellous bone compressions in zone 6 (75.8%). No adapter fractures occurred for CoCr components. The treatment and anchoring system of the short stem studied yielded good results and allowed revision using standard stems in all patients.

    Blood serum samples collected from randomly selected groups of 100 persons inhabiting rural community 'A' located in eastern Poland and exposed to floods by the Vistula river, and 98 persons inhabiting rural community 'B', also located in eastern Poland, but in the area not exposed to floods were examined by the microscopic agglutination test (MAT) for the presence of antibodies against 18 Leptospira serovars. Positive results showed 3% of serum samples collected from community 'A', while the seroprevalence in community 'B' was 9.2%, being insignificantly higher than in community 'A'. For both examined communities (n=198), a significant positive correlation was found between the prevalence and titer of seropositive response and age of examined people (r=0.145, p=0.042). No significant differences were found between the prevalence of positive reactions in males and females (p>0.05). The reactions with 10 serovars of Leptospira (Australis, Autumnalis, Hebdomadis, Hardjo, Sejroe, Zanoni, Bataviae, Bratislava, Canicola and Grippotyphosa), belonging to 3 species (L. interrogans, L. borgpetersenii, L. kirschneri), were found in the examined communities. From both communities, of 12 persons demonstrating positive results in MAT, 9 showed reaction with one serovar, 2 with two serovars and 1 with three serovars. The highest titers found during the examination did not exceeded 800. In conclusion, our results suggest that there is only a slight, if any, hazard of an leptospirosis epidemic after the flood that afflicted eastern Poland in the year 2010 and the general epidemiological situation of leptospirosis in eastern Poland. Although there does not seem to be any cause for concern, further research is needed. PMID:22742803

  20. Detection and identification of Chlamydophila psittaci in asymptomatic parrots in Poland

    2012-01-01

    Background Psittacosis, an avian disease caused by Chlamydophila psittaci, can manifest as an acute, protracted, or chronic illness, but can also be asymptomatic. C. psittaci can persist in the host for months to years, often without causing obvious illness, and therefore poses a threat for zoonotic outbreak. We investigated the prevalence of C. psittaci from 156 tracheal swab samples from 34 different species of parrots in Poland, and determined the genotype of strains from the positive samples. Results An overall prevalence of 10.3% was observed using two different PCR assays, both providing similar results. Thirteen of the PCR-positive samples were genotype A, two were genotype B, and one could not be classified. Conclusions These results indicate widespread dissemination of C. psittaci in Polish psittacine populations, without any clinical signs of chlamydiosis, and hence could pose a zoonotic hazard. PCR screening provided a definitive diagnosis of psittacosis, and subsequent ompA gene analysis could be helpful for better understanding the epidemiology of the C. psittaci genotypes. To the best of our knowledge, this is the first report of the incidence of C. psittaci in parrots in Poland. PMID:23206592

    AIM: To describe the risk profile of patients in hospital with hepatitis C virus (HCV) infection in Poland. METHOD: Using a structured questionnaire, all patients with confirmed HCV infection were interviewed about the risk factors. RESULTS: Among the 250 patients studied, transfusion before 1993 was the primary risk factor in 26%, intravenous drug use setting in 9% and occupational exposure in health-care in 9%. Women were more likely to have a history of occupational exposure or transfusion before 1993 and less likely to undergo minor surgery. Known nosocomial risk factors (transfusion before 1993, dialysis) were responsible for 27% of infections, probable nosocomial factors (transfusions after 1992, minor surgery) for 14% and further 9% were occupationally acquired infections. CONCLUSION: A careful history investigation can identify a known or probable risk factor for HCV acquisition in 59% of patients with HCV infection. Preventive activities in Poland should focus on infection control measures in health-care setting. PMID:16440435

    Poland syndrome is a rare congenital anomaly characterized by a unilateral congenital absence of the sternocostal head of the pectoralis major muscle. The absence of the pectoralis major does not only result in chest asymmetry but also in a missing anterior axillary fold, which is essential for natural anatomical appearance in both male and female patients. In Poland syndrome patients, we perform bipolar latissimus dorsi flap transfer, which can be associated with a sublatissimus implant in women. All procedures are performed through a single short midaxillary incision, and tendon translocation in this technique allows the creation of the anterior axillary fold and thus a natural chest appearance. Moreover, this technique can be performed by any plastic surgeon operating under a basic operating room setting. PMID:27622115

    This research, conducted in 1998 and 2008, uses go/no-go data to investigate the fundamentals of cognitive functioning in the inhibitory control ability of Japanese children. 844 subjects from kindergarten to junior high school participated in go/no-go task experiments. Performance of go/no-go tasks, which are frequently used to investigate response inhibition, measures a variety of cognitive components besides response inhibition. With normal brain development, the ability to inhibit responses improves substantially in adolescence. An increase over time in the error rate during the go/no-go tasks of subjects of the same age indicates that these processes are not functioning properly. Comparisons between the 1998 and 2008 data revealed several differences in error rates. In 2008, there were increases in the number of errors in groups from each age range. The comparison also revealed that overall error rates peaked at later ages in the 2008 subjects. Taken together, these results show changing conditions in the inhibitory function of the prefrontal cortex. However, the reason for these changing conditions remains unclear. While a lifestyle questionnaire revealed several differences in factors such as bedtimes and hours spent watching TV, analysis did not reveal a significant correlation. PMID:25061475

    Data from 2 separate studies were used to examine the relationships of axillary or thoracic skin temperature to rectal temperature and to determine the phase relationships of the circadian rhythms of these temperatures. In study 1, axillary skin and rectal temperatures were recorded in 19 healthy women, 21 to 36 years of age. In study 2, thoracic skin and rectal temperatures were recorded in 74 healthy women, 39 to 59 years of age. In both studies, temperatures were recorded continuously for 24 h while subjects carried out normal activities. Axillary and thoracic probes were insulated purposely to prevent ambient effects. Cosinor analysis was employed to estimate circadian rhythm mesor, amplitude, and acrophase. In addition, correlations between temperatures at various measurement sites were calculated and agreement determined. The circadian timing of axillary and skin temperature did not closely approximate that of rectal temperature: the mean acrophase (clock time) for study 1 was 18:57 h for axillary temperature and 16:12 h for rectal; for study 2, it was 03:05 h for thoracic and 15:05 h for rectal. Across individual subjects, the correlations of axillary or thoracic temperatures with rectal temperatures were variable. Results do not support the use of either axillary or skin temperature as a substitute for rectal temperature in circadian rhythm research related to adult women. PMID:14737919

    The paper studies a particular electrode system, two flat parallel electrodes with a dielectric plate having a small circular hole between them. Its main feature is that the region of the strong electric field is located far from metal electrode surfaces, which permits one to preclude the injection charge formation and to observe field-enhanced dissociation (the Wien effect) leading to the emergence of electrohydrodynamic (EHD) flow. The described electrode system was studied by way of both computer simulation and experiment. The latter was conducted with the help of the particle image velocimetry (or PIV) technique. The numerical research used trusted software package COMSOL Multiphysics, which allows solving the complete set of EHD equations and obtaining the EHD flow structure. Basing on the computer simulation and the comparison with experimental investigation results, it was concluded that the Wien effect is capable of causing intense (several centimeters per second) EHD flows in low-conducting liquids and has to be taken into account when dealing with EHD devices.

    The Environmental Mapping and Analysis Programme EnMAP is a hyperspectral satellite mission, supposed to be launched into space in the near future. EnMAP is designed to be revolutionary in terms of spectral resolution and signal-to-noise ratio. Nevertheless, it will provide a relatively high spatial resolution also. In order to exploit the capacities of this future mission, its data have been simulated by other authors in previous work. EnMAP will differ from other spaceborne and airborne hyperspectral sensors. Thus, the assumption that the standard classification algorithms from other sensors will perform best for EnMAP as well cannot by upheld since proof. Unfortunately, until today, relatively few studies have been published to investigate classification algorithms for EnMAP. Thus, the authors of this study, who have provided some insights into classifying simulated EnMAP data before, aim to encourage future studies by opening the EnMAP contest. The EnMAP contest consists in a benchmark dataset provided for algorithm development, which is presented herein. For demonstrative purposes, this report also represents two classification results which have already been realized. It furthermore provides a roadmap for other scientists interested in taking part in the EnMAP contest.

    Analyses of historical or modern populations indicate a strong relationship between mortality level and standard of living, measured, among other factors, by degree of urbanization. The aim of this study was to assess mortality rates in children of up to 5 years of age in two populations living under different conditions in central modern Poland at the end of the 19th century: the rural parish of Kowal, under Russian partition, and Toruń, an industrial and urbanized centre under Prussian partition. Data on births and deaths were taken from birth certificate registries and from the Prussian statistics yearbooks for 1876-1894. Death rates of children aged 0-5 years were calculated, and also for annual age ranges. The urban population had lower birth rates (37.19‰), natural increase rates (8.0‰), population dynamics rates (1.26‰), which provide information about the relation between two components of a natural increase, i.e. births and deaths, and an over-mortality of boys in relation to girls. In the rural population these values were all higher: 53.67‰, 18.11‰ and 1.59‰ respectively. No impact was found of social stratification on child mortality in the wide age group of 0-5 years. However, for subsequent one-year age groups significant relationships between mortality level and size and industrialization level of the population centres were noted. The living conditions of infants in Toruń, although being in a better position as an area annexed by Prussia, were markedly worse than those of rural Kowal Parish. In the urban centre infant mortality was slightly over 269 for 1000 live born, and in Kowal Parish it was 163 for 1000 live born. The high infant mortality was balanced in Toruń by the higher mortality levels of children aged 2-5 years compared with Kowal Parish. Natural selection in the city had the greatest impact on infants, who did not have the protective influence of breast-feeding because women had to return to work shortly after giving

    This study analyzed the anti-myeloma effect of zoledronic acid monotherapy by investigating patients at the time of asymptomatic biochemical relapse. One hundred patients were randomized to receive either zoledronic acid (4 mg iv/4 weeks, 12 doses) (n=51) or not (n=49). Experimental and control groups were well balanced for disease and prognostic features. Zoledronic acid did not show an antitumor effect according to changes in M-component. However, there were fewer symptomatic progressions in the experimental group than in the control group (34 versus 41, respectively; P=0.05) resulting in a median time to symptoms of 16 versus 10 months (P=0.161). The median time to next therapy was also slightly longer for the treated group than the untreated, control group (13.4 versus 10.1 months), although the difference was not statistically significant (P=0.360). The pattern of relapses was different for treated versus control patients: progressive bone disease (8 versus 20), anemia (24 versus 18), renal dysfunction (1 versus 2), and plasmacytomas (1 versus 1, respectively). This concurred with fewer skeletal-related events in the treated group than in the control group (2 versus 14), with a projected 4-year event proportion of 6% versus 40% (P<0.001). In summary, zoledronic acid monotherapy does not show an antitumor effect on biochemical relapses in multiple myeloma, but does reduce the risk of progression with symptomatic bone disease and skeletal complications.

    There is conflicting evidence about the merits of mobile bearings in total knee replacement, partly because most randomised controlled trials (RCTs) have not been adequately powered. We report the results of a multicentre RCT of mobile versus fixed bearings. This was part of the knee arthroplasty trial (KAT), where 539 patients were randomly allocated to mobile or fixed bearings and analysed on an intention-to-treat basis. The primary outcome measure was the Oxford Knee Score (OKS) plus secondary measures including Short Form-12, EuroQol EQ-5D, costs, cost-effectiveness and need for further surgery. There was no significant difference between the groups pre-operatively: mean OKS was 17.18 (sd 7.60) in the mobile-bearing group and 16.49 (sd 7.40) in the fixed-bearing group. At five years mean OKS was 33.19 (sd 16.68) and 33.65 (sd 9.68), respectively. There was no significant difference between trial groups in OKS at five years (-1.12 (95% confidence interval -2.77 to 0.52) or any of the other outcome measures. Furthermore, there was no significant difference in the proportion of patients with knee-related re-operations or in total costs. In this appropriately powered RCT, over the first five years after total knee replacement functional outcomes, re-operation rates and healthcare costs appear to be the same irrespective of whether a mobile or fixed bearing is used.

    The problem of the anisotropy and heterogeneity of karstic aquifers has been previously described. The Opole-Zawadzkie Major Groundwater Body (south-west Poland) was chosen for this investigation. The parameters for anisotropy were analysed on the basis of well yield and observation of macro-fractures (field scale) compared with micro-fractures. Sta-tistical tools were used to assess the directions and values of anisotropy. The estimated parameters were tested on two different models realized in Visual Modflow code. The anisotropy of hydraulic conductivity was recognized as an es-sential factor for groundwater flow direction and water table depletion prognosis as well as for water budget modification. The second model (M2), representing anisotropy flow conditions, gave an 11% lower value of safe yield in com-parison with the first model (M1-isotropic). Additionally, anisotropy conditions caused water table lowering and limitation of aquifer recharge. The results of these studies indicate the need for more attention to be paid to the anisotropy problem in the area, where fracture-karstic aquifers are the main source of groundwater supply.

    Carbon source alternatives for denitrification belong to the highest research area priorities as they allow to optimize N removal within the existing capacities. In particular, some food industry effluents appear to be good candidates for such alternatives due to their high C/N ratios and high content of readily biodegradable organic fraction. The aim of this study was to determine the immediate effects of dosing different types of industrial wastewater on the denitrification capability of process biomass originating from the "Wschod" WWTP in Gdansk (northern Poland). Three types of industrial wastewater (effluents from a distillery, brewery and fish-pickling factory) were tested in two kinds of batch experiments. The results of this study revealed that the investigated industrial wastewater can be a potential external carbon source to improve denitrification efficiency. The observed single nitrate utilization rates (NURs) were ranging from 2.4 to 6.0 g N/(kg VSS.h) and were comparable to the rates associated with the utilization of readily biodegradable COD in the settled wastewater. When the NURs were measured during anoxic P uptake, the P uptake rates did not appear to be adversely affected by the addition of any carbon source. PMID:19151486

    In June of 2000, biogeochemical study was carried out in three ecosystems of the Holy Cross Mountains (south-central Poland). This paper presents element concentrations and stable sulfur (and in one site lead) isotope ratios in rocks, detailed soil profiles, and plant bioindicators including epiphytic lichen Hypogymnia physodes (L.) Nyl., mosses (Pleurozium schreberi (Brid.) Mitt., Hypnum cupressiforme Hedw. S. Str., Hylocomium splendens (Hedw.) B.S.G.), Scots pine (Pinus sylvestris L.), common birch (Betula pendula Roth.), aspen (Populus tremula L.) and English oak (Quercus robur L.). Chemical analyses were performed with ICP-AES and AAS methods in the accredited laboratory (Central Chemical Laboratory of the Polish Geological Institute in Warsaw). The principal objective of this study was to compare the chemical composition of rocks, soils and selected plant bioindicators between investigation sites using the same methods of sample collection, preparation and analyses. The results of this study have shown that there is a high variability in concentrations of elements in plant bioindicators from the same sites that can not be explained only by soil properties or anthropogenic influence. This conclusion indicates that for biomonitoring purposes (especially with vascular plants) we cannot neglect individual features of the species examined. PMID:16308778

    Objectives The goal of the article is to present the changes in morbidity and costs of systemic lupus erythematosus (SLE) in Poland in the 2008–2012 period, depending on the province of residence of the patients based on data reported to the public payer – the National Health Fund. Material and methods Based on the ICD-10 code and the patient's personal identity number, the number of patients and medical costs (cost of hospitalization, pharmaceutical, medical procedures, dialysis and specialist consultations) were calculated by province (voivodeship) and urban or rural residence. Results Annually on average in the assessed period in Poland approximately 20 000 patients were diagnosed with SLE. The studied group was dominated by women (they were 5.2 times more numerous). The morbidity rate was 52.183 patients per 100 thousand inhabitants. Most patients were in the age range of 48–56 years. Average annual expenses for this group of patients over the examined period were USD 16,327 million. Two times more was expended on patients inhabiting cities, approximately 4 times more on women. Calculated per patient, the average cost of therapy was USD 810.63. Conclusions The population of SLE patients in Poland is highly stable. The results of analysis indicate 1.64 times more frequent occurrence in urban areas, which may be connected with availability of doctors. The SLE treatment costs in Poland are much lower than in other countries, which is related mainly to the fact that therapy with biological drugs is not financed.

    This paper presents the background, objectives, and preliminary outcomes from the first year of activities of the Polish-Norwegian project CHIHE (Climate Change Impact on Hydrological Extremes). The project aims to estimate the influence of climate changes on extreme river flows (low and high) and to evaluate the impact on the frequency of occurrence of hydrological extremes. Eight "twinned" catchments in Poland and Norway serve as case studies. We present the procedures of the catchment selection applied in Norway and Poland and a database consisting of near-natural ten Polish and eight Norwegian catchments constructed for the purpose of climate impact assessment. Climate projections for selected catchments are described and compared with observations of temperature and precipitation available for the reference period. Future changes based on those projections are analysed and assessed for two periods, the near future (2021-2050) and the far-future (2071-2100). The results indicate increases in precipitation and temperature in the periods and regions studied both in Poland and Norway.

    PASSEQ 2006-2008 (Passive Seismic Experiment in TESZ; Wilde-Piórko et al, 2008) was the biggest so far passive seismic experiment in the area of Central Europe (Poland, Germany, Czech Republic and Lithuania). 196 seismic stations (including 49 broadband seismometers) worked simultaneously for over two years. During experiment multiple types of data recorders and seismometers were used making analysis more complex and time consuming. Dataset was unified and repaired to start the detection of local seismic events. Two different approaches for detection were applied for stations located in Poland. One used standard STA/LTA triggers (Carl Johnson's STA/LTA algorithm) and grid search to classify and locate events. Result was manually verified. Other approach used Real Time Recurrent Network (RTRN) detection (Wiszniowski et al, 2014). Both methods gave similar results showing four previously unknown seismic events located in area of Gulf Of Gdańsk in southern Baltic Sea. The investigation of local seismicity is a good opportunity for verification of new seismic models of lithosphere in the area. In this paper we discuss both detection methods with their pros and cons (accuracy, efficiency, manual work required, scalability). We also show details of all detected and previously unknown events in discussed area. This work was partially supported by NCN grant UMO-2011/01/B/ST10/06653.

    Postmortem parasitic examinations of the large intestines of 725 slaughtered horses from individual farmers in southeastern Poland were carried out. The examinations were carried out monthly since February 2006 until January 2007 (except for August 2007 because of a technological stoppage in the slaughterhouse). The examinations included the intensiveness and extensiveness of the infestation of the Strongylidae belonging to the Strongylus genus. The Strongylidae were found in 26.5% of the examined horses. Strongylus vulgaris was the most dominant nematode and had a 22.8% prevalence, Strongylus edentatus was carried by 18.3% of the horses. Strongylus equinus was identified only in 1.7% of the examined horses. Our findings revealed that combined infestation of S. vulgaris and S. edentatus occurred in 100 (52.1%) of the 725 horses infected by the Strongylidae. The present results indicate that the lowest prevalence of strongyle species except for S. equinus was found in January, February, and March. However, it is difficult to draw a conclusion because of an extremely low extensiveness of infestation. The results indicate that the prevalence of the Strongylidae in horses from southeastern Poland is limited. PMID:22961235

    Noise is one of the most common physical risks in the workplace. Long term exposure to its high levels (above 80-85 dB) can pose a significant threat to health of workers, including hearing loss. Noise can also be a burdensome factor hampering work, causing stress and various health problems. In the European Union about 80 million workers (1/3 of total working population) complain about noise. In Poland, there are about 200 thousand workers exposed to noise in excess of MAI values. For years noise-induced hearing loss has been at the top of the list of occupational diseases. This paper presents a review of the data on noise hazards in the EU countries based on the reports of the European Foundation for the Improvement of Living and Working Conditions and publications of the European Agency for Safety and Health at Work. The statistical data on working conditions in Poland (including noise-induced risks) obtained from the Central Statistical Office and statistical data on occupational diseases (including hearing loss) elaborated by the Nofer Institute of Occupational Medicine in Łódź were the subject of analysis. The article also presents the results of noise measurements and surveys carried out in selected national companies. The obtained results indicate the necessity for both objective and subjective assessments of noise hazards in the workplace. PMID:23394010

    Serum samples of 474 wild birds, 378 horses, and 42 humans with meningitis and lymphocytic meningitis were collected between 2010 and 2014 from different areas of Poland. West Nile virus (WNV) antibodies were detected using competition enzyme linked immunosorbent assays: ELISA-1 ID Screen West Nile Competition, IDvet, ELISA-2 ID Screen West Nile IgM Capture, and ELISA-3 Ingezim West Nile Compac. The antibodies were found in 63 (13.29%) out of 474 wild bird serum samples and in one (0.26%) out of 378 horse serum samples. Fourteen (33.33%) out of 42 sera from patients were positive against WNV antigen and one serum was doubtful. Positive samples obtained in birds were next retested with virus microneutralisation test to confirm positive results and cross-reactions with other antigens of the Japanese encephalitis complex. We suspect that positive serological results in humans, birds, and horses indicate that WNV can be somehow closely related with the ecosystem in Poland. PMID:25866767

    A study of comparison of water vapor mixing ratio profiles, relative humidity profiles, and cloud vertical structures using two different instruments, a multiwavelength Aerosol-Depolarization-Raman lidar and radiosoundings, is presented. The observations were taken by the lidar located in Warsaw center and the radiosoundings located about 30km to the North in Legionowo (Poland). We compared the ground-based remote sensing technology with in-situ method in order to improve knowledge about water content thought the atmosphere and cloud formation. The method used for retrieving the cloud vertical structure can be improved comparing the radiosonde results with the lidar observations, which show promising results.

    2011-10-01

    Until recently, it has been assumed that pelagic crinoids, the roveacrinids (Roveacrinida, Crinoidea), became extinct during the Cretaceous-Paleogene boundary event. Recent finds of well-preserved roveacrinidal remains (brachials and radials) in the Danian (Early Paleogene) of Poland showed that they survived into the earliest Cenozoic. This group was thus characterized as a "dead clade walking". Here, we present fossil evidence that these pelagic crinoids survived in Poland until at least the Middle Miocene (Badenian, ca. 14 Myr ago)—more than 50 Myr after their supposed extinction. These Miocene roveacrinids constitute the first documented evidence of Roveacrinida in strata of Neogene age, thus prolonging the stratigraphic range of pelagic crinoids. This find characterizes the order as a "Lazarus taxon" rather than a "dead clade walking" group.

    The construction of a nuclear power plant is under consideration in Poland. One of the sites under discussion is near Lubiatowo, located on the cost of the Baltic Sea northwest of Gdansk. An assessment of possible environmental consequences is carried out for 88 real meteorological cases with the Lagrangian particle dispersion model FLEXPART. Based on literature research, three reactor designs (ABWR, EPR, AP 1000) were identified as being under discussion in Poland. For each of the designs, a set of accident scenarios was evaluated and two source terms per reactor design were selected for analysis. One of the selected source terms was a relatively large release while the second one was a severe accident with an intact containment. Considered endpoints of the calculations are ground contamination with Cs-137 and time-integrated concentrations of I-131 in air as well as committed doses. They are evaluated on a grid of ca. 3 km mesh size covering eastern Central Europe.

    In Poland, African swine fever (ASF) emerged in February 2014; by August 2015, the virus had been detected in >130 wild boar and in pigs in 3 backyard holdings. We evaluated ASF spread in Poland during these 18 months. Phylogenetic analysis indicated repeated incursions of genetically distinct ASF viruses of genotype II; the number of cases positively correlated wild boar density; and disease spread was very slow. More cases were reported during summer than autumn. The 18-month prevalence of ASF in areas under various animal movement restrictions was 18.6% among wild boar found dead or killed by vehicles and only 0.2% in hunted wild boar. Repeated introductions of the virus into the country, the primary role of wild boar in virus maintenance, and the slow spread of the disease indicate a need for enhanced biosecurity at pig holdings and continuous and intensive surveillance for fast detection of ASF.

    Propolis studies in Poland were initiated by Professor Stan Scheller in the 1960s. It was a team of Polish researchers who developed a method of introducing hydrophobic ethanol extracts of propolis (EEP) into aqueous solutions, which enabled the study of their biological properties. The studies performed in Poland showed that EEP possesses antioxidant, radioprotective, and immunostimulating properties. It was possible to demonstrate antibacterial activity of propolis on Gram-positive bacteria, virulent Mycobacterium tuberculosis, and protozoa as well as stimulating activity of aqueous extracts of propolis on proliferation of cells in vitro. Polish investigators showed that propolis stimulates regeneration of tissue, acts as antioxidant and radioprotector, has strong immunostimulative properties, affects animals' life span by extending it, and improves intellectual and life functions of the elderly.

    The article provides an overview of the development of electron beam X-ray microanalysis (EPMA) in Poland. Since the introduction by Prof. Bojarski of EMPA over 45 years ago, tremendous advances in methodologies and in instrumentation have been made in order to improve the precision of quantitative compositional analysis, spatial resolution and analytical sensitivity. This was possible due to the activity of Applied Crystallography Committee at the Polish Academy of Sciences, as well as the groups of researches working in the Institute for Ferrous Metallurgy (Gliwice), the Technical University of Warsaw, the Silesian Technical University (Katowice), the AGH-University of Sciences and Technology (Krakow), and the Institute of Materials Science and Metallurgy Polish Academy of Sciences (Krakow). Based on the research examples realized by these teams, conferences, seminars and congresses organized, as well as books and academic textbooks issued, the evolution of electron beam X-ray microanalysis in Poland is demonstrated.

    The agricultural sector in Poland is of considerable social and economic importance for the nation. Climate variability and change are of primary relevance to this largely climate-dependent sector. Changes in seven temperature-related agroclimatic indices (lengths of the growing season and of the frost-free season, days of occurrence of the last spring frost and of the first autumn frost; and annual sums of growing degree-days for three values of temperature threshold) in Poland in 1951-2010 are examined. As expected, they generally correspond to the overwhelming and ubiquitous warming. Many, but not all, detected trends are statistically significant. However, for some indices, strong natural variability overshadows eventual trends. Projections of temperature-related agroclimatic indices for the future, based on regional climate models, are also discussed.

    The stratigraphical distribution of Porosphaera globularis, a common calcareous sponge in the Upper Cretaceous (mostly Campanian and Maastrichtian) of Poland was studied. The presented material, both new and from museum collections, comes from the Campanian of the Miechow Synclinorium, in southern Poland, and from the Lower Campanian of Mielnik in the south-eastern part of the Mazury-Podlasie Homocline, in eastern Poland. The significance of the species in extra-regional correlation, its palaeobiogeography and stratigraphical potential is critically reviewed.

    Many fossil mammoth remains from more than 300 localities have been discovered over last 170 years in Poland. First radiocarbon dates of woolly mammoth from Poland were published in the 1960s and the 1970s. These dates must be regarded with caution due to absence of details of the used methods. Recently, about 40 fossil mammoth remains were radiocarbon dated by accelerator mass spectrometry (AMS) method in the Poznań Radiocarbon Laboratory. Dates are given as an uncalibrated radiocarbon dates (BP) and as calendar dates (cal. BP). The dates range from ca. 52 ka BP to ca. 13,2 ka BP (> 50,0 - ca. 16,1 cal. ka BP) and can be correlated with Oxygen Isotope Stage (OIS) 3 and OIS 2. A new radiocarbon evidence fits into the well known colonization pattern of Mammuthus primigenius in Central Europe and confirms a continuous distribution in the Grudziądz Interstadial (middle Weichselian, OIS 3) and the onset of the Last Glacial Maximum (LGM). On the other hand, the severe climatic circumstances lasting in conventional radiocarbon dates from ca. 22 ka BP to ca. 17 ka BP probably reduced the number of animals or even cased the withdrawal of woolly mammoth from the area north from the Sudetes and the Carpathian Mountains for 4-5 millennia. Only one date ca. 20,3 ka BP (ca. 24,2 cal, ka BP) is available from this time-span. Mammuthus primigenius reappeared in southern Poland ca. 14,6 ka BP (ca. 17,9 cal. BP) but soon had disappeared from this region because of marked reduction in open habitats at the beginning of Late Glacial Interglacial warming (Greenland Interstadial I or Bølling and Allerød) The latest available record from Poland is from Dzierżysław: 13,180±60 BP (ca. 15,600±400 cal. BP).

    Neisseria meningitidis of serogroup B (MenB) is currently responsible for more than 70% of cases of invasive meningococcal disease (IMD) in Poland and Europe as a whole. The aim of this study was to estimate strain coverage of a multicomponent meningococcal serogroup B vaccine (4CMenB) in Poland; the meningococcal antigen typing system (MATS) was used to test a panel of 196 invasive MenB strains isolated in Poland in 2010 and 2011. The strains were also characterized by MLST and sequencing of porA, factor H-binding protein (fHbp), Neisserial heparin-binding antigen (nhba) and Neisserial adhesin A (nadA) genes. MATS and molecular data were analyzed independently and in combination. The MATS results predicted that 83.7% (95% CI: 78.6-91.0%) of isolates would be covered by the 4CMenB vaccine; 59.2% by one vaccine antigen, 19.9% by two and 4.6% by three antigens. Coverage by each antigen was as follows: fHbp 73.0% (95% CI: 68.9-77.5%), NHBA 28.6% (95% CI: 13.3-47.4%), NadA 1.0% (95% CI: 1.0-2.0%) and PorA 10.2%. Molecular analysis revealed that the most frequent clonal complexes (ccs) were cc32 (33.2%), cc18 (17.9%) and cc41/44 (15.8%) with estimated coverage of 98.5%, 88.6% and 93.5%, respectively. Consistent with findings for other European countries, our study predicts high coverage by the 4CMenB vaccine in Poland. PMID:26686998

    The hepatitis C virus (HCV) is globally recognized as a serious public health concern. Current statistics indicate that approximately 2% of people worldwide and 1.9% of people in Poland suffer from HCV infection.This study was conducted to assess the anti-HCV seroprevalence in pregnant women in Poland and subsequently provide recommendations on the rationale for obligatory screening.A total of 42,274 women participated in our study, of which 16,130 were pregnant. We were granted access to their health data stored in the form of electronic medical records kept by the network of outpatient clinics throughout Poland.The lowest rate of positive anti-HCV test results was found in women ages 25 to 34 (0.73%); however, younger and older age groups had similar rates (15-24 = 0.86%; 35-44 = 0.84%). Additional analysis of data from the period between 2011 and 2014 revealed a downward trend in the proportion of positive anti-HCV tests among pregnant women (mean positive anti-HCV = -0.001 × year + 1.9451; R = 0.7274). Regardless of the gradual increase in the number of female patients undergoing screening between 2004 and 2015, there has been a constant decrease in the rate of positive cases. The rate of pregnant women potentially infected with HCV was twice as lower than that in a control group of women undergoing tests for other medical circumstances: 0.76% vs 1.67% (P < 0.0001).Analysis of real-world data of female patients in Poland provides evidence that screening based on an individual's medical history and behavioral risk factors in clinical circumstances would be more effective than obligatory testing of all pregnant women.

    "This article presents the process of migration of Kazakhs of Polish ancestry from Kazakhstan to Poland which has been taking place since the early 1990s. Poles deported in the past to Kazakhstan were mostly inhabitants of territories which did not belong to Poland; neither were they citizens of Poland. Therefore, the process of adaptation and integration was rather painful. The article points to factors that may simplify and those that may impede integration. The other problem...concerns the piecemeal policy towards Kazakhstan Poles, adopted by the Polish government, which seems risky if not dangerous. The author explains why it may cause a huge wave of illegal immigration to Poland." PMID:12294305

The prevalence of back pain, its intensity, location, and situations in which it occurred were assessed with a questionnaire. Results. Among 1089 respondents, 830 (76.2%) admitted that they had experienced back pain at various frequencies within the year preceding the study. Back pain was located mainly in the lumbar segment (74.8%). Mild pains were dominant, which was declared by 44.7% of the respondents. Girls experienced back pain significantly more frequently than boys (52.2% versus 47.8%, P < 0.05). Conclusions. The research revealed that back pain is a common phenomenon. The prevalence of back pain in children and youth living in southeast Poland is similar to the frequency of occurrence of such complaints occurring in peers in other countries. It seems significant to monitor the remaining regions of Poland in order to define the scale of the problem and to look for the risk factors of back pain in children and youth to undertake efficient prophylactic actions.

    Ashworthius sidemi, a nematode belonging to the family of Trichostrongylidae, is a primary parasite of the Asian deer, mainly sika deer (Cervus nippon), with which it was introduced to Ukraine, as well as Slovakia, the Czech Republic and France. Migrating red deer carried this parasite from neighboring countries to Polish territory. Until now, in Poland, this parasite has been recorded in European bison, red deer, roe deer and fallow deer. As a result of post-mortem examinations of 10 elk, 2 of them from the Augustów Forest and Biebrza Marshes, A. sidemi were found in abomasa for the first time in Poland. The intensity of the invasions was 120 and 7 specimens, respectively. This finding of Ashworthius sidemi in elk indicates a further expansion of the focus of ashworthiosis in BiaŁowieża towards the north into the Biebrza Marshes and the Augustowska Forest. The growth of the elk population and their tendency for long distance migrations can contribute to the spread of the parasitosis in much greater distances than deer. On the basis of our own research and data from the literature, the current spread of ashworthiosis in Poland is discussed. PMID:24338312

    A nautilid faunule of seven specimens, comprising Eutrephoceras bouchardianum (d'Orbigny, 1840), Cymatoceras deslongchampsianum (d'Orbigny, 1840), and Cymatoceras tourtiae (Schlüter, 1876) is described from a condensed middle Cenomanian interval at Annopol, Poland. C. tourtiae is recorded for the first time in Poland. The studied material consists of reworked phosphatised internal moulds of phragmocones, which may be of early or middle Cenomanian age, given the stratigraphic range of the associated ammonites. The nautilid moulds vary in inferred mode of infilling, and in intensity of abrasion, bioerosion and mineralisation. The sediment entered the phragmocones in two ways: 1) through punctures in the shell, the result of bioerosion or mechanical damage; 2) through siphonal openings by intracameral currents. In contrast to the fossil moulds from the Albian phosphorites of Annopol, which originated via direct precipitation of apatite around and/or inside fossils, the present nautilid moulds seem to have originated through secondary phosphatisation of the initially calcareous moulds. Diversity of taphonomic signatures in nautilid material from the middle Cenomanian interval at Annopol is compatible with the complex, multievent depositional scenario proposed for this level.

    With the collapse of socialism, the number of nongovernmental organizations in Eastern Europe increased dramatically, as part of democracy and capitalism building. In the West, NGOs have served as key players in shaping the response of the HIV epidemic, reflecting both the withdrawal of the state from service provision in line with neoliberal reforms and the activist roots from which many of these organizations originated. As a result, AIDS NGOs and the people who work in them are often characterized as engaging in an activist endeavor in order to affect social and political change that will enable better prevention and care. This article explores the extent to which a similar framework applies to AIDS NGOs in Poland and Eastern Europe, more generally, where the notion of “anti-politics” and disengagement from political activism remains strong. As they developed in Poland, AIDS NGOs have focused on caring for clients, cultivating a professional identity, and abstaining from politics, to the eschewal of advocacy activities on behalf of their clients. This orientation has implications for the types of HIV prevention programs these organizations offer, as well as the possibilities for collaborating with researchers and service providers from the West.

    Toxocariasis is a helminthozoonosis due to the infection of humans with larvae belonging to the Toxocara genus. Humans become infected as a result of accidental consumption of infected eggs containing third stage larvae (L3) nematodes from Toxocara canis or Toxocara cati species. Toxocariasis was recognized for the first time in the early 1950s, and the first cases of toxocariasis in Poland were described a few years later. Toxocariasis is clinically classified into several types: classic and incomplete visceral larva migrans (VLM) syndrome, ocular larva migrans (OLM) syndrome, neurological toxocariasis (NLM), covert toxocariasis and asymptomatic toxocariasis. In 1994-2005, 18,367 sera of people suspected of being infected with Toxocara were analysed, 1.8-76% had anti- Toxocara antibodies. In the period 1978-2009, 1,022 clinical cases of toxocariasis were recognized in Poland. In the opinion of the authors, in order to reduce the frequency of toxocariasis in human populations, some prophylaxis should undertaken, e.g. public education of zoonotic diseases, systematic control of animal, deworming of pets, cleaning pets' faeces by the owners.

    Introduction Ultraviolet phototherapy (UVP) is widely used in dermatological practice for the treatment of various skin diseases. Numerous studies support its beneficial curing effectiveness; however, overexposure to ultraviolet radiation can cause adverse health effects, such as sunburn reaction, erythema response, cataract, skin aging, etc. For these reasons, it is of special importance to monitor performance of UVP cabins using a calibration system to evaluate the UV doses incident upon the patient. Material and methods A mechanized cabin control system (CCS) is proposed. It consists of radiometers with a wide and narrow field of view to estimate the body irradiation and to identify malfunctioning cabin tubes. Quality control and quality assurance procedures are developed to keep high accuracy of the calibration procedure. The CCS has been used in the examination of two different types of UVP cabins routinely working in Poland. Results It allows precise calculation of UV doses and spatial variability of UV radiance inside the cabin, thus providing uncertainties of the doses assigned by medical staff. The CCS could potentially serve as a primary standard for monitoring various UVP cabins working in Poland. Conclusions The methodology developed to quantify UV doses in UVP cabins may be easily extended to any UV radiation source. PMID:25624865

    The purpose of this paper was to present the current data on the risk of toxocarosis in humans in Poland and to give an overview of the clinical and diagnostic aspects of the disease. The number of reported clinical cases of Toxocara infection in children in Poland in medical literature has increased recently. The results of field surveys aimed to evaluate the soil contamination with geohelminth eggs conducted during the last few years showed that Toxocara is the most common zoonotic agent in urban public sites and in rural settlements. The questionnaire revealed rural inhabitants' low awareness of zoonotic parasite threats to humans. In particular parents should be advised as to what proper preventive measures to undertake to eliminate the toxocarosis risk factors for children in rural environment. Prevention of initial environment contamination with Toxocara canis and T. cati eggs, which includes proper treatment regimes to eliminate patent infections in dogs and cats and preventing pets from defecating in public areas and private households is vital. To provide the public with suitably presented information as well as pet owners with uniform recommendations, a close collaboration between veterinary and public health professionals is crucial.

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

    Introduction The magnetotelluric survey was made along a regional profile, which runs across Poland from south-west to north-east during 2005-2006 years. The profile crosses major geological structures of Central Poland, including the Variscan Externides and Variscan foredeep, the Transeuropean Suture Zone and the marginal zone of East European Craton. The main objectives of the project include identification of sub-Zechstein sedimentary structures and evaluation of resistivity distribution within the deep crust, especially at the contact of East European Precambrian Craton and Central Europe Paleozoic structures. The length of the profile is about 700 km; 161 deep magnetotelluric sounding sites were made with a medium spacing of about 4 km. Data acquisition and processing The recording of the components of natural electromagnetic field was made with a broad range of frequencies, varying from 0.0003 Hz up to 575 Hz with use of MT-1 system of Electromagnetic Instruments Incorporation. This frequency band allowed obtaining the information about geology ranging from a few dozen meters to approximately 100 km, depending on the vertical distribution of the resistivity inside geological medium. To reduce the electromagnetic noise, magnetic and electric remote reference was applied. A remote reference site was located at a distance of over 100 km of field sites. Processing of the recorded data included the estimation of the components of impedance tensor (Zxx, Zxy, Zyx and Zyy ), with use of robust type procedures. The components of the impedance tensor allowed in a subsequent step for calculation of field curves for two orientations of the measurement system (XY - described further as the TM mode and YX - TE mode) and additional parameters of the medium like skew, strike, pole diagrams etc. Recording of the vertical component of electromagnetic field (Hz) allowed calculation of tipper parameter T.

    Multi-model ensemble climate projections in the ENSEMBLES Project of the EU allowed the authors to quantify selected extreme-weather indices for Poland, of importance to climate impacts on systems and sectors. Among indices were: number of days in a year with high value of the heat index; with high maximum and minimum temperatures; length of vegetation period; and number of consecutive dry days. Agricultural, hydrological, and human health indices were applied to evaluate the changing risk of weather extremes in Poland in three sectors. To achieve this, model-based simulations were compared for two time horizons, a century apart, i.e., 1961-1990 and 2061-2090. Climate changes, and in particular increases in temperature and changes in rainfall, have strong impacts on agriculture via weather extremes - droughts and heat waves. The crop yield depends particularly on water availability in the plant development phase. To estimate the changes in present and future yield of two crops important for Polish agriculture i.e., potatoes and wheat, some simple empirical models were used. For these crops, decrease of yield is projected for most of the country, with national means of yield change being: -2.175 t/ha for potatoes and -0.539 t/ha for wheat. Already now, in most of Poland, evapotranspiration exceeds precipitation during summer, hence the water storage (in surface water bodies, soil and ground) decreases. Summer precipitation deficit is projected to increase considerably in the future. The additional water supplies (above precipitation) needed to use the agro-potential of the environment would increase by half. Analysis of water balance components (now and in the projected future) can corroborate such conclusions. As regards climate and health, a composite index, proposed in this paper, is a product of the number of senior discomfort days and the number of seniors (aged 65+). The value of this index is projected to increase over 8-fold during 100 years. This is an

    Tree-ring based temperature reconstructions form the scientific backbone of the current debate over global change, and they are the major part of the palaeo data base used for the IPCC report. However, long temperature reconstructions derived from temperate lowland trees growing well within their distributional limits in central Europe are not part of the IPCC report, which is an essential gap in the international data base. It appears that dendroclimatological analysis at temperate lowland sites was so far difficult to perform mainly for three reasons: diffuse climate-growth relationships, the lack of long chronologies due to absence of sufficient numbers of long-living trees and the potential loss of low-frequency signals due to the short length of the sample segments. We present two robust multi-centennial reconstructions of winter temperatures and summer precipitation based on pine and oak tree-ring widths chronologies from northern Poland, where so far no long tree-ring based reconstructions were available. We compared the new records with global, hemispherical and regional reconstructions, and found good agreement with some of them. In comparison, the winter temperature of our reconstruction, however, did not indicate any modern warming nor did the summer precipitation reconstruction suggest any modern 20th century changes. In a second step, we measured cell structures and developed chronologies of parameters such as cell wall thickness and cell lumen area. We used our new method (Liang et al. 2013a,b) applying confocal laser scanning microscopy to increment core surfaces for efficient histometric analyses. We focused on samples covering the last century because meteorological data necessary for calibration studies were available for direct comparisons. It was demonstrated that the correlations with climate were strong and different from those found for tree-ring widths (e.g., N-Poland oak-vessel-lumen-area-chronology with previous September-to-December mean

    Underground coal mining is associated with large quantities of gangue. In the past, the majority of gangue was not utilized but was placed in the vicinity of the coalmines forming cone-shaped dumps. Some of them contained even millions of tons of rock. Nowadays, environmental precautions extort larger utilization of any kind of waste materials, for example in road construction, civil engineering or as stowing in underground abandoned workings. Examination of the composition of waste dumps, including radioactivity, is thus an important issue. The paper presents results of a radiological survey carried out in several dumps located in the Upper Silesian Coal Basin in the south of Poland. Measurements of samples were carried out with the use of a gamma-ray spectrometer. Activity concentration results for the uranium and thorium decay chains are discussed.

    Lake Żabińskie is the main study site of CLIMPOL, a project which aims at establishing a quantitative reconstruction of climate change in northern Poland during the last millennium. The lake is located in the Masurian Lake District (54°07'54.5"N; 21°59'01.1"E) and presents features typical for kettle-hole lakes, i.e. a small surface area (41.6 ha) and a considerable depth (44.4 m) in the central part of the lake bottom. A set of gravity and piston cores collected from the deepest part of the lake indicate that the sediment record contains an undisturbed and continuous sequence of varved deposits. A regular monitoring of lake water properties and modern sedimentation was initiated to better understand the influences of limnology on the processes of varve formation and preservation in this lake. During monthly field campaigns a broad range of physical and chemical parameters of the lake water column as well as sediment fluxes were measured. Seasonal changes in sediment composition registered in sediment trap allow establishing documentation of an annual deposition model which is here compared with results of microstratigraphic investigations of thin sections and high-resolution XRF scanning of impregnated sediment slabs. Multiple calcite deposition during growing season of one year is well reflected in the complex structure of varves which include up to six individual calcite laminae. During spring and summer, pennate and centric diatoms occur in addition to calcite crystals. In the late summer grains of vivianite and pyrite are present. Chrysophyte cysts are also very common but no distinct seasonality can be observed. During autumn and winter period minerogenic and organic detritus occurs. XRF measurements confirm that highest Ca concentrations occur during spring and summer which are followed by distinct maxima in Fe, K and S concentrations. Si concentrations, which represent mainly biogenic silica content in the sediments are consistent with Ca while Mn

    2015-10-01

    In this paper, we document the Middle Triassic marine fauna recovered from the fissure/cave system of Stare Gliny (southern Poland) developed in the Devonian host dolomite. The fossils are mostly represented by in situ preserved and small-sized holdfasts of crinoids (Crinoidea) that are attached to the cave walls. Other fossils found in the cave infills include articulated brittle stars and brachiopods. Our findings constitute the oldest Mesozoic evidence for troglophile crinoids. We suggest that troglomorphism in these echinoderms was likely related to protection against predation, which underscores the magnitude of anti-predatory adaptations to increased predation pressure that occurred during the Early Mesozoic Marine Revolution.

    The selenium was quantified in the caps, stalks or a whole fruiting bodies of king bolete (Boletus edulis), brown birch scaber stalk (Leccinum scabrum), parasol mushroom (Macrolepiota procera), fly agaric (Amanita muscaria) and poison pax (Paxillus involutus) collected at the various regions of Poland in 1998-2001. King bolete, parasol mushroom and fly agaric were a much more abundant in selenium than brown birch scaber stalk or poison pax. Some differences were observed between the selenium content of the particular species collected at different sites as well as depending on anatomical part of the fruiting body. PMID:14755851

    Natural water reservoirs are very valuable floristic sites in Poland. Among them, the most important for preservation of biodiversity of flora are limnocrenic karst springs. The long-term process of human pressure on habitats of this type caused disturbance of their biological balance. Changes in the water regime, industrial development and chemisation of agriculture, especially in the period of last two hundred years, led to systematic disappearance of localities of many plant species connected with rare habitats and also to appear numerous invasive plant species. They are: Acorus calamus, Echinocystis lobata, Elodea canadensis, Erechtites hieraciifolia, Impatiens glandulifera, Solidago canadensis, S. gigantea and S. graminifolia. Fielworks were conducted in 2010-2014.

    During the Pleistocene large continental ice sheets developed in Scandinavia and North America. Ice-loading caused bending of the lithosphere and outward flow in the mantle. Glacial loading is one of the most prominent tectono-mechanical event in the geological history of northern Poland. The Pomeranian region was subjected several times to a load equivalent of more than 1 km of rocks, which led to severe increase in both vertical and horizontal stresses in the upper crustal rocks. During deglaciation a rapid decrease in vertical stress is observed, which leads to destabilization of the crust - most recent postglacial faults scarps in northern Sweden indicate glacially induced earthquakes of magnitude ~Mw8. The presence of the ice-sheet altered as well the near-surface thermal structure - thermal gradient inversion is still observable in NW Poland. The glacially related processes might have left an important mark in the sedimentary cover of northern Poland, especially with regard to fracture reopening, changes in stress state, and damage development. In the present study, we model lithospheric bending caused by glacial load, but our point of interest lies in the overlying sediments. Typical glacial isostatic studies model the response of (visco-) elastic lithosphere over viscoelastic or viscous asthenosphere subjected to external loads. In our model, we introduce viscoelastic sedimentary layers at the top of this stack and examine the stress relaxation patterns therein. As a case study for our modelling, we used geological profiles from northern Poland, near locality of Wejherowo, which are considered to have unconventional gas potential. The Paleozoic profile of this area is dominated by almost 1 km thick Silurian-Ordovician shale deposits, which are interbedded with thin and strong limestone layers. This sequence is underlain by Cambrian shales and sandstones, and finally at ~3 km depth - Precambrian crystalline rocks. Above the Silurian there are approximately

    In this article, the author describes the recent changes in patterns of drug use in Poland in the light of available data. A much higher incidence of use has been seen in the 1980s, and there are indications that this can be accounted for by increased use among young people from the manual working class. Social deprivation may play a part in the etiology of the 1980s "epidemic," and evidence is put forward in support of this view. Both patterns of use and the policies that have been introduced to deal with them are viewed in terms of the political, economic, and social context of post-Solidarity perestroika. PMID:2787787

    Seasonal fluctuations in mortality and their causes in the nineteenth century Polish rural populations: wealthy, agriculturally and economically advanced populations from Wielkopolska, and poor populations from Silesia and Galicia (southern Poland) were described. Data-sources included parish death registers from the Roman Catholic parish of Dziekanowice in the region of Wielkopolska, Prussian statistical yearbooks for the Pozna Province as well as information from previous publications regarding Silesia and Galicia. The 19th century patterns were compared with those in present-day Poland. The occurrence of seasonality of deaths was assessed with: the Chi-squared test, the Kolmogorov-Smirnov test, and the Autoregressive Integrated Moving Average Models (ARIMA). In all populations there was a winter maximum of the number of deaths, while the minimum occurred in early summer. In the poor populations of Silesia and Galicia another statistically significant increase in the incidence of deaths was observed in the early spring. In the rich and modern villages of Wielkopolska there was no spring increase in the number of deaths, however, in all populations of Wielkopolska, irrespective of a particular pattern, a secondary mortality peak occurred in the late summer and autumn. Statistical tests used in this study did not show any clear differences in the distribution of the seasonality of deaths between the populations of Wielkopolska on the one hand, and the populations from Galicia and Silesia, on the other hand. The statistical significance of differences was, however, evident between populations representing the two distinguished by secondary peaks death seasonality patterns. Seasonal death increase split the populations under study into two groups according to the criterion of wealth. PMID:26898041

    Previous studies have shown that ragweed pollen arrives in Poland from sources in the south, in Slovakia, the Czech Republic, Hungary and Austria. It is likely that ragweed pollen also arrives from sources in the southeast (e.g. Ukraine). This hypothesis was investigated using 13 years of pollen data and back-trajectory analysis. Ambrosia pollen data were collected at three sites in Poland, Rzeszów, Kraków and Poznań. The amount of ragweed pollen recorded at Rzeszów was significantly higher than in Poznań and Kraków. This can be related to either a higher abundance of local populations of Ambrosia in south-east Poland or the proximity of Rzeszów to foreign sources of ragweed pollen. The combined results of pollen measurements and air mass trajectory calculations identified plumes of Ambrosia pollen that were recorded at Rzeszów, Kraków and Poznań on 4 and 5 September 1999 and 3 September 2002. These plumes arrived at the pollen-monitoring sites from an easterly direction, indicating sources of Ambrosia pollen in eastern Poland or Ukraine. This identifies Ukraine as a possible new source of ragweed pollen for Poland and therefore an important source area of Ambrosia pollen on the European Continent.

  16. Value of children and fertility: Results from a cross-cultural comparative survey in eighteen areas in Asia, Africa, Europe and America.

    For explaining cross-cultural differences in fertility behavior, this paper conjoins three complementary approaches: the 'demand'-based economic theory of fertility (ETF), a revised version of the 'supply'-based 'value-of-children' (VOC)-approach as a special theory of the general social theory of social production functions and the framing theory of variable rationality. A comprehensive model is specified that encompasses the variable efficiency of having children for the optimization of physical well-being and of social esteem of (potential) parents; it also accounts for the variable rationality of fertility decisions. The model is tested with a data set that comprises information on VOC and fertility of women within the social settings of 18 areas (Peoples Republic of China, North and South India, Indonesia, Palestine, Israel, Turkey, Ghana, South Africa, East and West Germany, the Czech Republic, France, Russia, Poland, Estonia, the United States and Jamaica). Latent class analysis is used to establish a measurement model for the costs and benefits of children and to analyze area differences by a two-level multinomial-model. Two-level Cox-regressions are used to estimate the effects of perceived costs and benefits of children, individual resources and context opportunities, with births of different parity as dependents. This simultaneous test in a cross-cultural context goes beyond the current state of fertility research and provides evidence about the cross-cultural validity of the model, the systematic effects of VOC on fertility and the changing rationality of fertility decisions during demographic transition and socio-economic change.

    Two commonly used receptor models, positive matrix factorization (PMF) and chemical mass balance (CMB), are applied to 3-year PM2.5 data at two urban sites (Atlanta, GA and Birmingham, AL) and two rural sites (Yorkville, GA and Centreville, AL). Source apportionment results using the two receptor models are analyzed and compared. Both models are able to identify major sources at all sites, though the degree of agreements and correlations between source impacts estimated by PMF and CMB varies depending on sources and receptor sites. Estimated contributions of secondary inorganic particles are the most comparable and highly correlated. The lesser comparability and correlations of estimated contributions of other sources (mostly primary) may be attributed to several factors. Resolved source profiles in PMF have more processed (or aged) characteristics resulting in part from atmospheric mixing and condensation of oxidized compounds, whereas source profiles used in CMB are obtained from measurements of emission sources with minimum amount of atmospheric processing. The PMF profiles vary from site to site; both atmospheric processing and local source variability contribute. In comparison, the CMB profiles obtained from a limited number of emission measurements may not be locally representative even if they are regionally representative. The omission of possible known or unknown sources due to lack of proper source profiles or proper "marker" species may also cause the differences in the source apportionment results. In addition, the implication for PM time-series health study is discussed based on the results from this study.

Our investigations confirmed that Hg in urban aerosol samples was predominantly related to local industrial and commercial emissions, whereas the main source of Hg in particulate matter collected at the forest site was connected with regional anthropogenic processes. This paper provides the results of the first long-term measurements of size-fractionated particulate mercury conducted in central Poland, which could be an important insight into atmospheric Hg processes within such a scarcely investigated part of Europe.

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

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

    The doses of gamma radiation, concentrations of radium isotopes in water and sediments, radon concentration and concentration of alpha potential energy of radon decay products in the copper ore mine and in the mining region in the vicinity of Lubin town in Poland are presented. These data served as a basis for the assessment of radiological hazard to the mine workers and general public. The results of this assessment indicate that radiological hazard in the region does not differ substantially from typical values associated with natural radiation background. The calculated average annual effective dose for copper miners is 1.48 mSv. In general, copper ore mines can be regarded as radiologically safe workplaces.
