    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

    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

    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

    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.

    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.

  13. Comparative risk assessment: an international comparison of methodologies and results.

    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

    2015-12-01

    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

    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

  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.

    2003-10-01

    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.

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.

    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

    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.

    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

    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.

    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 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

    Population densities of large herbivores are determined by the diverse effects of density-dependent and independent environmental factors. 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

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

    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.

  13. Testing Friction Laws by Comparing Simulation Results With Experiments of Spontaneous Dynamic Rupture

    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 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.

    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.

    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.

    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

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

    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

    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.

    In July 1994, the Idaho National Engineering Laboratory (INEL), under a contract from U.S. Department of Energy`s (DOE) Environment Management Office of Science and Technology (OST, EM-50) published a report entitled {open_quotes}Integrated Thermal Treatment System Study - Phase 1 Results{close_quotes} (EGG-MS-11211). This report was the culmination of over a year of analysis involving scientists and engineers within the DOE complex and from private industry. 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.

    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.

    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%.

  17. Demographic and settlement transformations in peripheral regions (based on the example of eastern Poland)

    2012-01-01

    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.

  18. Weight discrepancy and body appreciation among women in Poland and Britain.

    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

    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.

    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

    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

    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.

    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.

  8. Four methods of attitude determination for spin-stabilized spacecraft with applications and comparative results

    Smith, G. A.

    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.

    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. This work is partially funded by AGH research grant no 11.11.140.319. Murata K. J., Smith R. L., 1946.

    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

    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

    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.

    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

  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

    Economic transformation has had a positive influence in Poland on statistical indices that characterize occupational safety and health (OSH). Surprisingly, working conditions have not deteriorated. Methodological differences make comparing statistical data in various countries difficult. OHS standards in Poland are harmonized with European and international ones. Testing and certification, quality and OSH management systems are very important, as are education and training in OSH and international cooperation. Increasing unemployment is a significant threat to the development of OSH or even maintenance of its current state. PMID:11743908

    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.
