    Poland is an important case study in understanding the role of international cooperation in reducing the risk of global climate change. A the world's fourth largest coal producer, the nation occupies a key position in the political economy of a changing Europe. More importantly, Poland is pursuing energy policy reforms that half of the world must follow to reduce greenhouse gas emissions and prosper economically. Poland is undergoing profound economic and environmental change. This nation of 38 million people hopes to shift from planning to markets to allocate economic resources, and at the same time to conserve and protect environmental resources. Per capita incomes are only one-fourth of West Germany's, for example, but per capita energy use (and emissions of carbon dioxide) is just as high. High energy intensity causes much of Poland's serious air and water pollution. Economic efficiency could help reduce carbon and sulfur emissions, but the capital required to improve the energy infrastructure is scarce. The combination of these problems has reduced GNP per capita 9 percent over the last decade

  2. Double strand break repair: two mechanisms in competition but tightly linked to cell cycle

    DNA double strand breaks (DSB) are highly toxic damage although they can be induced to create genetic diversity. Two distinct pathways can repair DSB: Homologous Recombination (HR) and Non Homologous End Joining (NHEJ). If un- or mis-repaired, this damage can lead to cancer. Thus, it is essential to investigate how these two pathways are regulated for DSB repair. NHEJ inhibition leads to HR DSB repair stimulation. However, this channeling to HR is tightly linked to cell cycle since NHEJ and HR are active in G1/early S and late S/G2, respectively. Our results suggest that G1-unrepaired DSB go through S phase to be repaired by HR in G2. Those results allow a better understanding of DSB repair mechanisms regulation. (author)

    NY-ESO-1 has been suggested as therapeutic cancer vaccine in prostate cancer. This study was undertaken to explore the relationship of NY-ESO-1 with tumor phenotype, biochemical recurrence, and molecular subgroups in hormone-naive prostate cancers. NY-ESO-1 immunohistochemistry was analyzed on a tissue microarray containing 11,152 prostate cancer samples. Results were compared to clinically follow-up data, ERG status, and deletions on PTEN, 3p13, 5q21, and 6q15. NY-ESO-1 expression was absent in benign prostate glands. In prostate cancer, NY-ESO-1 positivity was found 8.8% of our 8,761 interpretable tumors including 5.8% with weak, 2.5% with moderate, and 0.5% with strong expression. There was a threefold higher rate of NY-ESO-1 expression in ERG fusion positive tumors than in ERG negative cancers (P ESO-1 expression was associated with early biochemical recurrence (P = 0.0002) and high Gleason grade (P ESO-1 expression was also linked to PTEN (P = 0.0012) and 6q15 deletions (P = 0.0005). Our observations indicate a tight link of NY-ESO-1 expression to ERG activation and (to a lesser extent) PTEN- and 6q15-deletions in prostate cancer. The impact of these interactions on the likelihood of response to immunotherapy is unclear. The prognostic impact of NY-ESO-1 expression is little and not independent of histologic variables. © 2014 Wiley Periodicals, Inc.

    Invasive insects may dramatically alter resource cycling and productivity in forest ecosystems. Yet, although responses of individual trees should both reflect and affect ecosystem-scale responses, relationships between physiological- and ecosystem-scale responses to invasive insects have not been extensively studied. To address this issue, we examined changes in soil nitrogen (N) cycling, N uptake and allocation, and needle biochemistry and physiology in eastern hemlock (Tsuga canadensis (L) Carr) saplings, associated with infestation by the hemlock woolly adelgid (HWA) (Adelges tsugae Annand), an invasive insect causing widespread decline of eastern hemlock in the eastern USA. Compared with uninfested saplings, infested saplings had soils that exhibited faster nitrification rates, and more needle (15)N uptake, N and total protein concentrations. However, these variables did not clearly covary. Further, within infested saplings, needle N concentration did not vary with HWA density. Light-saturated net photosynthetic rates (Asat) declined by 42% as HWA density increased from 0 to 3 adelgids per needle, but did not vary with needle N concentration. Rather, Asat varied with stomatal conductance, which was highest at the lowest HWA density and accounted for 79% of the variation in Asat. Photosynthetic light response did not differ among HWA densities. Our results suggest that the effects of HWA infestation on soil N pools and fluxes, (15)N uptake, needle N and protein concentrations, and needle physiology may not be tightly coupled under at least some conditions. This pattern may reflect direct effects of the HWA on N uptake by host trees, as well as effects of other scale-dependent factors, such as tree hydrology, affected by HWA activity. © The Author 2015.

    Long-range enhancers of transcription are a key component of the genomic regulatory architecture. Recent studies have identified bi-directionally transcribed RNAs emanating from these enhancers known as eRNAs. However, it remains unclear how tightly coupled eRNA production is with enhancer activity. Through our systematic search for long-range elements that interact with the interferon-β gene, a model system for studying inducible transcription, we have identified a novel enhancer, which we have named L2 that regulates the expression of interferon-β. We have demonstrated its virus-inducible enhancer activity by analyzing epigenomic profiles, transcription factor association, nascent RNA production and activity in reporter assays. This enhancer exhibits intimately linked virus-inducible enhancer and bidirectional promoter activity that is largely dependent on a conserved Interferon Stimulated Response Element and robustly generates virus inducible eRNAs. Notably, its enhancer and promoter activities are fully retained in reporter assays even upon a complete elimination of its associated eRNA sequences. Finally, we show that L2 regulates IFNB1 expression by siRNA knockdown of eRNAs, and the deletion of L2 in a BAC transfection assay. Thus, L2 is a novel enhancer that regulates IFNB1 and whose eRNAs exert significant activity in vivo that is distinct from those activities recapitulated in the luciferase reporter assays. © The Author(s) 2014.

    The Italian National Institute for Nuclear Physics (INFN) has successfully tested the first model of a new fast-ramping curved dipole magnet. This is great news for CERN, which sees the advance as holding potential for the future of the SPS.   The first model of a new fast-ramping curved dipole magnet being prepared for cryogenic testing at the LASA laboratory (INFN Milano, Italy). On 16 July INFN introduced an innovative dipole magnet. With a length of some 4 metres, it can produce a 4.5 Tesla magnetic field and achieve a tighter bend than ever before (the bending radius has been squeezed to a remarkable 66.7 metres). This new magnet was designed in the first instance for GSI’s SIS300 synchrotron (in Germany), which will require 60 dipoles of this type. "Achieving such a tight bend demanded a major R&D effort," stressed Pasquale Fabbricatore, the spokesman of the INFN collaboration responsible for the magnet’s development. "We had to not o...

  7. Tight closure and vanishing theorems

    International Nuclear Information System (INIS)

    Smith, K.E.

    2001-01-01

    Tight closure has become a thriving branch of commutative algebra since it was first introduced by Mel Hochster and Craig Huneke in 1986. Over the past few years, it has become increasingly clear that tight closure has deep connections with complex algebraic geometry as well, especially with those areas of algebraic geometry where vanishing theorems play a starring role. The purpose of these lectures is to introduce tight closure and to explain some of these connections with algebraic geometry. Tight closure is basically a technique for harnessing the power of the Frobenius map. The use of the Frobenius map to prove theorems about complex algebraic varieties is a familiar technique in algebraic geometry, so it should perhaps come as no surprise that tight closure is applicable to algebraic geometry. On the other hand, it seems that so far we are only seeing the tip of a large and very beautiful iceberg in terms of tight closure's interpretation and applications to algebraic geometry. Interestingly, although tight closure is a 'characteristic p' tool, many of the problems where tight closure has proved useful have also yielded to analytic (L2) techniques. Despite some striking parallels, there had been no specific result directly linking tight closure and L∼ techniques. Recently, however, the equivalence of an ideal central to the theory of tight closure was shown to be equivalent to a certain 'multiplier ideal' first defined using L2 methods. Presumably, deeper connections will continue to emerge. There are two main types of problems for which tight closure has been helpful: in identifying nice structure and in establishing uniform behavior. The original algebraic applications of tight closure include, for example, a quick proof of the Hochster-Roberts theorem on the Cohen-Macaulayness of rings of invariants, and also a refined version of the Brianqon-Skoda theorem on the uniform behaviour of integral closures of powers of ideals. More recent, geometric

  8. Shaping drug policy in Poland.

    2016-05-01

    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.

    Sunflower oil is one of the major sources of edible oil. As the second largest hybrid crop in the world, hybrid sunflowers are developed by using the PET1 cytoplasmic male sterility system that contributes to a 20 % yield advantage over the open-pollinated varieties. However, sunflower production in North America has recently been threatened by the evolution of new virulent pathotypes of sunflower rust caused by the fungus Puccinia helianthi Schwein. Rf ANN-1742, an 'HA 89' backcross restorer line derived from wild annual sunflower (Helianthus annuus L.), was identified as resistant to the newly emerged rust races. The aim of this study was to elucidate the inheritance of rust resistance and male fertility restoration and identify the chromosome location of the underlying genes in Rf ANN-1742. Chi-squared analysis of the segregation of rust response and male fertility in F(2) and F(3) populations revealed that both traits are controlled by single dominant genes, and that the rust resistance gene is closely linked to the restorer gene in the coupling phase. The two genes were designated as R ( 11 ) and Rf5, respectively. A set of 723 mapped SSR markers of sunflower was used to screen the polymorphism between HA 89 and the resistant plant. Bulked segregant analysis subsequently located R ( 11 ) on linkage group (LG) 13 of sunflower. Based on the SSR analyses of 192 F(2) individuals, R ( 11 ) and Rf5 both mapped to the lower end of LG13 at a genetic distance of 1.6 cM, and shared a common marker, ORS728, which was mapped 1.3 cM proximal to Rf5 and 0.3 cM distal to R ( 11 ) (Rf5/ORS728/R ( 11 )). Two additional SSRs were linked to Rf5 and R ( 11 ): ORS995 was 4.5 cM distal to Rf5 and ORS45 was 1.0 cM proximal to R ( 11 ). The advantage of such an introduced alien segment harboring two genes is its large phenotypic effect and simple inheritance, thereby facilitating their rapid deployment in sunflower breeding programs. Suppressed recombination was observed in LGs 2, 9

    2010-10-22

    Based on the shearlet transform we present a general construction of continuous tight frames for L2(ℝ2) from any sufficiently smooth function with anisotropic moments. This includes for example compactly supported systems, piecewise polynomial systems, or both. From our earlier results in Grohs (Technical report, KAUST, 2009) it follows that these systems enjoy the same desirable approximation properties for directional data as the previous bandlimited and very specific constructions due to Kutyniok and Labate (Trans. Am. Math. Soc. 361:2719-2754, 2009). We also show that the representation formulas we derive are in a sense optimal for the shearlet transform. © 2010 Springer Science+Business Media, LLC.

  12. The links between implementing ISA 540 and mitigating the practice of smoothing reported net earnings using write-offs of accounts receivable and inventory by reporting entities in Poland

    Full Text Available The paper addresses the question of the links between implementing ISA 540 and mitigating the practice of smoothing reported net earnings using write-offs of accounts receivable and inventory by reporting entities in Poland. The research question stems from the previous analysis carried out by the author in which evidence was provided that reporting entities in Poland in the period 2000–2010 effectively used write-offs of accounts receivable and inventory in order to mitigate fluctuations of reported net earnings. This paper provides evidence that before implementing ISA 540 reporting entities used write-offs of receivables and inventory for income smoothing in effective manner, however in the period after implementing the standard (2009–2014 no link was observed between the write-offs and reduced fluctuations of reported net earnings. The research has been carried out using Wilcoxon signed-rank test used to check equality of medians of mean deviations of net earnings before write-offs of receivables and inventory and mean deviations of net earnings after write-offs. For the period before implementing ISA 540 there are grounds to reject the hypothesis of equality of medians of mean deviations of net earnings, however in the post-adoption period there is no justification to reject the hypothesis of equality of medians. The research provides evidence of positive impact of ISA 540 mitigating the processes of accounting earnings management. The indicated regularity does not apply to banks, because within this group of companies we have not observed the use of write-offs of loan receivables in order to reduce the variability of net earnings before implementing ISA 540 and in the period following the implementation of the standard.

  13. Novel Alleles of Two Tightly Linked Genes Encoding Polygalacturonase-Inhibiting Proteins (VrPGIP1 and VrPGIP2 Associated with the Br Locus That Confer Bruchid (Callosobruchus spp. Resistance to Mungbean (Vigna radiata Accession V2709

    Full Text Available Nearly all mungbean cultivars are completely susceptible to seed bruchids (Callosobruchus chinensis and Callosobruchus maculatus. Breeding bruchid-resistant mungbean is a major goal in mungbean breeding programs. Recently, we demonstrated in mungbean (Vigna radiata accession V2802 that VrPGIP2, which encodes a polygalacturonase inhibiting protein (PGIP, is the Br locus responsible for resistance to C. chinensis and C. maculatus. In this study, mapping in mungbean accession V2709 using a BC11F2 population of 355 individuals revealed that a single major quantitative trait locus, which controlled resistance to both C. chinensis and C. maculatus, was located in a 237.35 Kb region of mungbean chromosome 5 that contained eight annotated genes, including VrPGIP1 (LOC106760236 and VrPGIP2 (LOC106760237. VrPGIP1 and VrPGIP2 are located next to each other and are only 27.56 Kb apart. Sequencing VrPGIP1 and VrPGIP2 in “V2709” revealed new alleles for both VrPGIP1 and VrPGIP2, named VrPGIP1-1 and VrPGIP2-2, respectively. VrPGIP2-2 has one single nucleotide polymorphism (SNP at position 554 of wild type VrPGIP2. This SNP is a guanine to cystine substitution and causes a proline to arginine change at residue 185 in the VrPGIP2 of “V2709”. VrPGIP1-1 has 43 SNPs compared with wild type and “V2802”, and 20 cause amino acid changes in VrPGIP1. One change is threonine to proline at residue 185 in VrPGIP1, which is the same as in VrPGIP2. Sequence alignments of VrPGIP2 and VrPGIP1 from “V2709” with common bean (Phaseolus vulgaris PGIP2 revealed that residue 185 in VrPGIP2 and VrPGIP1 contributes to the secondary structures of proteins that affect interactions between PGIP and polygalacturonase, and that some amino acid changes in VrPGIP1 also affect interactions between PGIP and polygalacturonase. Thus, tightly linked VrPGIP1 and VrPGIP2 are the likely genes at the Br locus that confer bruchid resistance in mungbean “V2709”.

    2013-01-01

    The Polish authorities are doing everything in their power to block Nord Stream 2, the Russian natural gas pipeline project that will double (by 2019) Nord Stream 1 through the Baltic Sea. Gazprom's Nord Stream 2 (in which European companies such as Engie (France), Uniper and Wintershall (Germany), OMV (Austria) and Shell are involved) will poses a risk, according to Poland, to the gas supply of central European countries (and notably Ukraine). Poland also intends to stop all its gas imports from Russia after 2022 (end of the Yamal contract): the country is therefore developing its capacity to increase its own natural gas production and has just inaugurated a liquefied natural gas terminal on the Baltic Sea. A gas pipeline is also in project, that will link Norway to Poland. For power generation, the nuclear energy option is also studied

    2014-01-01

    The aim of the article is evaluation of the epidemiological situation of hepatitis A in Poland in 2012. Assessment of epidemiological situation of hepatitis A was based on results from analysis of the annual bulletins: "Infectious diseases and poisonings in Poland in 2012", "Vaccinations in Poland in 2012", reports from individual cases and epidemiological investigations of outbreaks linked to hepatitis A, sent by Epidemiological Departments in Sanitary Epidemiological Stations to the Department of Epidemiology at NIPH-NIH. In Poland, 71 cases of hepatitis A were registered in 2012. The incidence of 0.17/ per 100 000 inhabitants was slightly higher than previous year. The incidence of hepatitis A ranged from 0.08/100 000 in Łódzkie and Podlaskie to 0.35/100 000 in Śląskie. The incidence of hepatitis A in men and women was at an approximate level and amounted to 0.19 and 0.18/100 000 respectively. The peak of incidence was recorded during the summer and autumn-winter months. In 2012 imported cases constituted 52.1% of all cases of hepatitis A. There were five outbreaks involving of 11 registered cases in 2012. In 2012, there was a slight increase in the incidence of hepatitis A in compared with the previous year. However, apart from that there were no significant changes in the epidemiological situation of hepatitis A. In Poland there is still very low endemicity for hepatitis A. Decreased incidence and the small number of people vaccinated against hepatitis A facilitates the accumulation of a fairly numerous population of persons susceptible to infection which is connected with the possibility to increase the number of cases of hepatitis A. Despite the fact that the current epidemiological situation of hepatitis A in Poland is good, the disease still requires monitoring and analysis within the framework of epidemiological surveillance system.

    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. © The Author 2015.

    Full Text Available Poland and Ukraine are the two biggest and most populated countries of Central and Eastern Europe. Because of their size, neighbourhood and position in the region the two countries have often been compared to France and Germany. Both countries are deeply interested in their mutual cooperation. Such situation steams from five factors: direct neighbourhood, common (albeit difficult history, attractiveness of the Polish labour market for the Ukrainians, membership of Poland in the Western structures, and last but not least, the Russian threat. Despite complimentary interests, both countries have difficulty to effectively develop their mutual relations and turn them into a real “strategic partnership”. These problems are due to the internal political and economic situation in Ukraine, limits imposed by the membership of Poland in the EU, Russian policy aiming at keeping Ukraine within its zone of influence and, finally, the EU reluctance to effectively engage in Ukraine.

  9. Nuclear Physics in Poland

    Wroblewski, A.K.

    2004-01-01

    Full text: This will be a short presentation of low and high energy nuclear physics in Poland, its history, essential results, and the present status. Nuclear physics in Poland has a tradition of hundred years. Research started just after the discovery of radium and polonium by Polish-born Maria Sklodowska-Curie and her husband Pierre Curie. Maria Sklodowska-Curie employed numerous Polish assistants in her Paris laboratory and supported radioactivity studies in Warsaw, her birth place, then under the occupation of tsarist Russia. In the first decades of the XXth century Poland was one of the leading countries in radioactivity studies. In the late 1930-ies a cyclotron was constructed in Warsaw and an ambitious 'Star of Poland' project was launched to study the cosmic rays. Unfortunately, the Second World War stopped all scientific activity in Poland. A large fraction of Polish physicists perished in the period 1939-1945. After the World War nuclear physics of low and high energy was rebuilt in Warsaw and Krakow. Already in 1952 Marian Danysz and Jerzy Pniewski discovered the first hypernucleus. This important discovery was essential to understand the properties of numerous new particles found in cosmic rays. Polish physicists entered intensive collaboration with both CERN and Dubna and took part also in research at other centers in Europe (DESY, GSI, GANIL, Julich, SACLAY) and the United States (Fermilab). At present the research is concentrated in Warsaw and Krakow (the two largest centers), and smaller teams, mostly theorists, are also in Bialystok, Katowice, Kielce, Lublin, Lodz and Wroclaw. Several years ago a heavy ion cyclotron was built in Warsaw. Among the important discoveries made by Polish nuclear physicists one may mention the theoretical works on superheavy elements and the recent discovery of the two-proton radioactivity

  10. Distribution of Vulpia species (Poaceae in Poland

    Full Text Available The distribution of four species of the genus Vulpia [V. myuros (L. C.C. Gmel., V. bromoides (L. S.F. Gray, V. ciliata Dumort. and V. geniculata (L. Link] reported in Poland has been studied. Currently, V. myuros and especially V. bromoides are very rare species, and their greatest concentration can be found only in the Lower Silesia region. The number of their localities decreased after 1950 and it seems resonable to include both species in the "red list" of threatened plants in Poland: V. myuros in the EN category, V. bromoides in the CR category. V. ciliata and V. geniculata are very rare ephemerophytes and their localities not confirmed during ca 60 years are of historical interest only.

    Full Text Available Field observations on the occurrence of soybean diseases were undertaken in the southern and central regions of Poland in the period 1976-1980. Most prevalent were foliage diseases caused by Peronospora manshurica, Pseudomonas syrinqae pv. glycinea and soybean mosaic virus (SMV. Sclerotinia sclerotiorum and Ascochyta sojaecola were reported as pathogens of local importance. The following pathogenic fungi: Botrytis cinerea, Fusarium culmorum, F. oxysporum and Rhizoctonia solani were also isolated from soybean.

  13. Abortion in Poland.

    Szawarski, Z

    1991-12-01

    As of July 1991 abortion is still legal in Poland. Currently the Polish Parliament has taken a break from the debate because the issue is so important that any decision must not be made in past. There is strong pressure from the Catholic Church to eliminate access to abortion. In the fall the Polish people will vote for and elect their first truly democratic Parliament. Abortion does not seem to be playing as important a role as other political issues. In 1956 a law was passed that allowed a woman to have an abortion for medical or social reasons. This law resulted in allowing women in Poland to use abortion as their primary form of contraception. The vast majority of the abortions were performed under the social justification. Then, when democracy same to Poland with the help of the Catholic Church, an unprecedented debate in the mass media, churches, and educational institutions was stirred up. The government attempted to stay out of the debate at first. But as people from different side of the debate saw that they had an opportunity to influence things in their favor, they began to politicize the issue. Currently there are 4 different drafts of the new Polish abortion law. 3 of them radically condemn abortion while the 4th condemns it as a method of family planning, but allows to terminate pregnancies in order to save the life of the mother.

  14. Poland's syndrome revisited.

    Science.gov (United States)

    Fokin, Alexander A; Robicsek, Francis

    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.

  15. Diagnosing the tight building syndrome

    Energy Technology Data Exchange (ETDEWEB)

    Rogers, S.A.

    1987-12-01

    Formaldehyde is but one of many chemicals capable of causing the tight building syndrome or environmentally induced illness (EI). The spectrum of symptoms it may induce includes attacks of headache, flushing, laryngitis, dizziness, nausea, extreme weakness, arthralgia, unwarranted depression, dysphonia, exhaustion, inability to think clearly, arrhythmia or muscle spasms. The nonspecificity of such symptoms can baffle physicians from many specialties. Presented herein is a simple office method for demonstrating that formaldehyde is among the etiologic agents triggering these symptoms. The very symptoms that patients complain of can be provoked within minutes, and subsequently abolished, with an intradermal injection of the appropriate strength of formaldehyde. This injection aids in convincing the patient of the cause of the symptoms so he can initiate measure to bring his disease under control.

  16. Invasive tightly coupled processor arrays

    CERN Document Server

    LARI, VAHID

    2016-01-01

    This book introduces new massively parallel computer (MPSoC) architectures called invasive tightly coupled processor arrays. It proposes strategies, architecture designs, and programming interfaces for invasive TCPAs that allow invading and subsequently executing loop programs with strict requirements or guarantees of non-functional execution qualities such as performance, power consumption, and reliability. For the first time, such a configurable processor array architecture consisting of locally interconnected VLIW processing elements can be claimed by programs, either in full or in part, using the principle of invasive computing. Invasive TCPAs provide unprecedented energy efficiency for the parallel execution of nested loop programs by avoiding any global memory access such as GPUs and may even support loops with complex dependencies such as loop-carried dependencies that are not amenable to parallel execution on GPUs. For this purpose, the book proposes different invasion strategies for claiming a desire...

    Coal power generation produces gases which pollute the environment and cause damage to vegetation and human health. Where alternative sources of energy are not economically viable, the only solution is to ensure that gas emissions are reduced to a minimum. The Department of Technical Co-operation is sponsoring a programme with the support of the Department of Research and Isotopes to demonstrate a technology which will show Poland, and possibly other countries, a way to attain European emission standards without the need to compromise industrial growth.

  1. Global Coal Trade. From Tightness to Oversupply

    International Nuclear Information System (INIS)

    Cornot-Gandolphe, Sylvie

    2013-01-01

    Over the past four years, international coal trade has been reshaped by China's surging imports. China, which was still a net exporter in 2008, became the world's first coal importer in 2011, taking over the position that Japan has occupied for three decades. Its imports have continued their rising trend and reached a record level in 2012, despite the country's economic slowdown. China imported 289 million tons of coal in 2012, up 30% over 2011. It now accounts for 23% of global imports. Although China is the world's largest coal producer, several factors have contributed to the sudden rise in its imports, including the higher cost of domestic coal relative to international prices and bottlenecks in transporting domestic coal to south-eastern provinces. More recently, another event shook the international coal business: the United States have been back on the market. The collapse of U.S. gas prices, to $4/million Btu in 2011 and even $2.75/million Btu in 2012, linked with the 'shale gas revolution', has made coal uncompetitive in the electricity sector, its main outlet on the U.S. market. U.S. coal demand dropped 4% in 2011 and 11% in 2012. The reduction in domestic demand has forced U.S. miners to look for overseas outlets. Their exports surged by 31% in 2011 and 16% in 2012. They reached 112 million tons in 2012, more than twice the level of 2009. The United States, which almost disappeared from the international steam coal market in the 2000's, have regained a larger share of the total coal export market, 9% in 2012, against 6% in 2009. These developments, although not directly linked, have a huge impact on the global market and pricing of coal. Chinese imports have helped the market to quickly recover from its low level of 2008-2009. The speed and magnitude of China's coal imports even shifts the market from a sluggish to a tight situation. Prices started to rise after their collapse in the second half of 2008 caused by the economic and financial crisis

  2. Poland and Global Threats

    Science.gov (United States)

    Kleer, Jerzy

    2016-01-01

    This essay seeks to present the specifics of global threats, as well as the reasons for them being universal in nature, and for their persistence. A certain classification of the threats is also engaged in. At the same time, an attempt is made to show the specific threats present - irrespective of their global counterparts - in different regions, and even in different states. The genesis and nature of the latter are demonstrated in a somewhat ad hoc manner by reference to the threats considered to face Poland. If the global threats are truly universal, and arise out of the changes taking place around the world in the last half-century (primarily around the twin phenomena of globalisation and the information revolution), a specific reverse kind of situation applies to decolonisation, plus the collapse of the communist system and the transformation into market economies that apply to formerly communist countries. Equally, some at least of the threats facing Poland may have even a longer history, given that they are very much influenced by past economic and political development, as well as the dominant cultural system.

  7. Sulphur in Poland

    Directory of Open Access Journals (Sweden)

    2001-12-01

    Full Text Available Poland belongs to one of the last countries with native sulphur mining. Its history begun in 15th century. Deposit area of Tarnobrzeg re-presents 80% of all known sulphur reserves in this country. All of explored deposits in this area were created by metasomatic alteration of sulphur bearing limestones with sulphur mineralised liquids, which arised from melt gypsum. The average content is 25 - 30% of sulphur in Tarnobrzeg area. Considerable parts of deposits are created by calcite and native sulphur. Gypstone, baryte and stroncianite have only minera-logic occurencies. The extensive native sulphur deposits account for 88% of the country´s sulphur production. There were five sulphur mines in operation: Jeziórko, Grêbów, Machów I, Machów II and Basznia, but operations in Basznia were ended in 1992 and Machów and Machów II were liquidated. The sixth mine Osiek is currently producing. Only the Machów I mine operated an open-pit extraction and refining process, the other four mines producing sulphur using a modified Frasch method that gives elemental sulphur of up to 99,9% purity. Sulphur is an important export commodity with foreign sales totalling around 1.5 - 2.5 Mt/y. Modern benefication methods, which allowing to achieve sulphur from hydrocarbons, are causing decrease of native sulphur prices in the world and bringing about reduction of mining activities for this raw material in Poland.

  8. Rubella in Poland in 2013.

    Korczyńska, Monika Roberta; Paradowska-Stankiewicz, Iwona

    2015-01-01

    In 2004, Poland has adopted the WHO goal of rubella elimination and congenital rubella syndrome prevention. The main target of the Programme is to stop transmission of the virus in the environment and prevention of congenital rubella in children. This can be achieved by carrying out the vaccination. Participation in the rubella elimination program requires clinical diagnosis of rubella cases and their confirmation with laboratory test. In Poland, until 2003, national vaccination recommendation included a dose of rubella vaccine only for girls aged 13 years. Among men, the incidence of measles remained high creating a risk of infection of non-immune pregnant women which may lead to the development of congenital rubella syndrome in the child. To assess epidemiological situation of rubella in Poland in 2013, including vaccination coverage in Polish population. The descriptive analysis was based on data retrieved from routine mandatory surveillance system and published in the annual bulletins "Infectious diseases and poisonings in Poland in 2013" and "Vaccinations in Poland in 2013" (MP. Czarkowski, Warszawa 2014, NIZP-PZH, GIS). In 2013, there was big epidemic of rubella in Poland--with 38,548 registered cases (6 times more than in 2012), incidence 84.4 per 100,000 (5 times higher than in the previous year). The highest incidence rate, regardless of gender and the environment, was observed among adolescents aged 15-19 years (911.6 per 100,000). The incidence of rubella in boys and men was significantly higher than the incidence in girls and women (181.4 versus 23.9). In 2013, two cases of congenital rubella syndrome were registered. Rubella epidemic which occurred in Poland in 2013 was the result of use in the past vaccination against rubella only for girls 13 years of age. The proportion of laboratory tests confirming/excluding rubella infection is still very low in Poland. In 2013, only 0.2% of rubella cases were laboratory confirmed.

    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

The highest number of cases was reported in mazowieckie voivodeship (35 321), the lowest in podlaskie voivodeship (5 346). The highest incidence was recorded in children aged 4 years. The chickenpox incidence among men was higher by 12.4% comparing to women (543.4). The incidence among rural residents (595.0) was higher by 9.8 % than among urban residents. Number of cases hospitalized due to mumps was 1 467. Number of people vaccinated against chickenpox was 63 608. In 2014, there was increase in the incidence of chickenpox in Poland. Since 2002 the number of people vaccinated against chickenpox increased. The increase in the number of people vaccinated against chickenpox would help maintain the downward trend in subsequent years.

    In 1998 Poland, along with all other Member States in the WHO European Region, implemented Measles Elimination Program coordinated by WHO. It requires achieving and maintaining very high vaccine coverage (>95%), recording all cases and suspected cases of measles, and laboratory testing of all suspected measles cases in the WHO Reference Laboratory. In Poland it is a Laboratory of Department of Virology, NIPH-NIH. To assess epidemiological situation of measles in Poland in 2012, including vaccination coverage in Polish population, and Measles Elimination Program implementation status. The descriptive analysis was based on data retrieved from routine mandatory surveillance system and published in the annual bulletins "Infectious diseases and poisonings in Poland in 2012" and "Vaccinations in Poland in 2012", and measles case-based reports from 2012 sent to the Department of Epidemiology NIPH-NIH by Sanitary-Epidemiological Stations. In total, there were 70 measles cases registered in Poland in 2012 (incidence 0.18 per 100 000). The highest incidence rate was observed among infants (2.08 per 100 000) and children aged 1 year (2.47 per 100 000). In 2012, 37 cases (52,9%) were hospitalized due to measles. No deaths from measles were reported. Vaccination coverage of children and youth aged 2-11 years ranged from 83.6% do 99.6% (primary vaccination in children born in 2011-2006) and from 76.6% do 96.7% (booster dose in children born in 2003-2001). Performance of the surveillance system was insufficient with only 127 measles-compatible cases reported in 2012 (33% of expected reports). Fifty cases (71%) were confirmed by IgM ELISA test. The epidemiological situation of measles deteriorated in 2012 in comparison to proceding year. The results indicate a need to further promote Measles Elimination Program in Poland, maintain the high immunisation coverage and improve measles surveillance system.

The descriptive analysis was based on data retrieved from routine mandatory surveillance system and published in the annual bulletins "Infectious diseases and poisonings in Poland in 2012" and "Vaccinations in Poland in 2012" (Czarkowski MP i in., Warszawa 2013, NIZP-PZH i GIS). Mumps cases were classified according to the criteria of surveillance case definition implemented in the European Union (Commission Decision of 28 April 2008 amending Decision 2002/253/EC). National Immunisation Programme for year 2012 was also used. In total, there were 2779 mumps cases registered in Poland in 2012. Incidence of mumps was 7.2 per 100 000 and it was higher by 7.5% in comparison with 2011 and lower by 19.4% in comparison to median for the years 2006-2010. The highest incidence rate was observed among children aged 5 years (71.8 per 100 000). Incidence in women (5.9) was lower than in men (8.6). In 2012, 25 people were hospitalized due to mumps. Vaccination coverage of children aged 3 years in Poland in 2012 was 97.9%. Systematic execution of mumps vaccination in accordance with the National Immunisation Programme resulted in a significant decrease in the number of registered cases. Due to the high vaccination coverage further decline in the number of cases is expected.

    Full Text Available The Orthodox educational system has been meeting important tasks, which is raising a general mental level of clergy and faithful. Its foundation was driven by needs of the Orthodox Church. Educating a young generation in the spirit of the Orthodoxy happened to be the main task of the enlightened class. Brotherhood, monastery and parish school were to be part of this program. The Orthodox education shaped religious life, helped preserve the religious and national identity of the believers. An evidence of that is the fact, that only those localities preserved “the Greek faith “, in which next to the monasteries were schools. Higher education, and especially Mohyla Academy, shaped by the then elite, played a vital role in the history of Orthodox Church in the Republic and neighboring countries. A similar role had to play in the interwar period College of Orthodox Theology at the University of Warsaw and in post-war Orthodox Section of the Christian Academy of Theology Presented here outline of history of Orthodox education in Poland indicates to the, appreciated by clergy and hierarchy, need of development of theological schools. Theological schools played and still play important role in shaping the attitudes of clergy and faithful. Schools provide necessary pastoral resources, shape Orthodox cultural and scientific environment. Theological education has remained an essential element for the proper functioning of Orthodox Church in the Polish Republic.

    A large number of chickenpox cases, occurring especially in children, indicates the rationale for the use of chickenpox vaccinations. In Poland since 2002, chickenpox vaccination is included in the National Immunisation Programme as recommended. To assess epidemiological situation of chickenpox in Poland in 2013 in comparison to previous years. The descriptive analysis was based on data retrieved from routine mandatory surveillance system and published in the annual bulletins "Infectious diseases and poisonings in Poland in 2013" and "Vaccinations in Poland in 2013" (Czarkowski MP i in., Warszawa 2014, NIZP-PZH i GIS). National Immunisation Programme for year 2013 was also used. In 2013, 178 501 cases of chickenpox were registered in Poland. The incidence was 463.6 and was lower than in 2012 (540.5). The highest number of cases was reported in mazowieckie voivodeship, the lowest in podlaskie voivodeship. The highest incidence was recorded in children aged 4 years (6 545.1 per 100,000). The chickenpox incidence among men (491.7) was higher by 12.4% comparing to women (437.3). The incidence among rural residents (497.2) was higher than among urban residents (441.7). Number of cases hospitalized due to mumps was 1 184. Number of people vaccinated against chickenpox was 57 168. In 2013, there was decrease in the incidence of chickenpox [corrected] in Poland with small fluctuations. Since 2002 the number of people vaccinated against chickenpox increased. The increase in the number of people vaccinated against chickenpox would help maintain the downward trend in subsequent years.

    In 2004, Poland has adopted the WHO goal of rubella elimination and congenital rubella syndrome prevention. Participation in the rubella elimination program requires clinical diagnosis of rubella to be confirmed with laboratory test. In Poland, until 2003, national vaccination recommendation included a dose of rubella vaccine only for girls aged 13 years. Among men, the incidence of measles remained high creating a risk of infection of non-immune pregnant women which may lead to the development of congenital rubella syndrome in the child. To assess epidemiological situation of rubella in Poland in 2012, including vaccination coverage in Polish population. The descriptive analysis was based on data retrieved from routine mandatory surveillance system and published in the annual bulletins "Infectious diseases and poisonings in Poland in 2012" and "Vaccinations in Poland in 2012". In 2012, there was a significant increase in the number of cases of rubella - 6 263 cases (in 2011, 4 290 cases) - and the increase in incidence (from 11.1 per 100 thousand. 16.3). The highest incidence rate, regardless of gender and the environment, was observed among adolescents aged 15-19 years (118.0 per 100 000). As in 2011, the incidence of rubella in boys and men was higher than the incidence in girls and women (25.6 versus 7.5). In 2012, no cases of congenital rubella syndrome were registered. The proportion of laboratory tests confirming/excluding rubella infection is still very low in Poland. In 2012, only 0.2% of rubella cases were laboratory confirmed.

    In 2004, Poland has adopted the WHO goal of rubella elimination and congenital rubella syndrome prevention. The main target of the Programme is to stop transmission of the virus in the environment and prevention of congenital rubella in children. In Poland participation in the rubella elimination program requires clinical diagnosis of rubella cases and their confirmation with laboratory tests. Vaccination against rubella was introduced in 1987, initially only in 13 - year-old girls. Since 2003, single jab vaccination against rubella, measles and mumps is used (MMR vaccine for all children: primary vaccination at the age 13-15 months and a booster vaccination at the age of 10). To assess epidemiological situation of rubella in Poland in 2014, including vaccination coverage in Polish population. The descriptive analysis was based on data retrieved from routine mandatory surveillance system and published in the annual bulletins “Infectious diseases and poisonings in Poland in 2014” and “Vaccinations in Poland in 2014” (MP. Czarkowski, Warszawa 2014, NIZP-PZH, GIS). In 2014, there was a significant decrease in the number of rubella cases - with registered 5891 cases (in 2013 - 38 548 cases) - and a decline in incidence (from 101.1 per 100 000 to 15.3). The highest incidence, regardless of gender and the environment was observed in the age group 5-6 years (respectively 93.8 and 109.4 per 100 000). Similarly to 2013, rubella incidence of males was higher than the incidence in girls and women (20.0 versus 10.9). In 2014, no cases of congenital rubella syndrome were registered. The proportion of laboratory tests confirming/excluding rubella infection is still very low in Poland. In 2014, only 0.6% of rubella cases were laboratory confirmed.

    The purpose of the study was evaluation of epidemiological situation of salmonellosis in Poland in 2012 compared to the previous years. The main source of data for this study are statistical overviews contained in the annual bulletins "Infectious Diseases in Poland in 2012" (NIZP-PZH, GIS, Warsaw 2013), reports from investigations obtained from the sanitary epidemiological stations. Information on deaths due to infectious and parasitic diseases registered in Poland in 2012 and earlier years is based on the data from the Department for Demographic Research of Central Statistical Office. For the purpose of surveillance cases were classified according to the case definition. In Poland in 2012, it was reported a total of 8 444 cases of zoonotic salmonellosis including 8 267 cases of intestinal salmonellosis and 177 of extraintestinal one. The incidence was 21.9/100 000. The criteria for a confirmed case met more than 94% of cases. The number of reported cases was lower than in 2011, reflecting the continued downward trend in the number of cases of salmonellosis in Poland. A very high percentage (69.4%) hospitalizations of people infected with zoonotic Salmonella remains. In outbreaks proportion of hospitalizations accounted for one third of the cases. Predominated children under the age of 5 years. Seven people died of salmonellosis. In 2012, it was reported 181 outbreaks caused by Salmonella in which 1 511 people still. They were mostly small family outbreaks. The most common etiological agent of salmonellosis in Poland is S. enteritidis, but slightly increases the percentage cases, for which no serologic type was determined. In 2012 it stood at 14%. This proportion was highest in the Pomorskie province and amounted to 58%. Keeping up for more than 10 years in the percentage of salmonellosis hospitalization rate at 70%, indicates underreporting of the disease in the country and mostly detection of the cases requiring hospital treatment.

    Yamamoto, Yasushi; Hiraiwa, Kouji; Morooka, Shinichi; Abe, Nobuaki

    An innovative fuel cycle system concept named BARS (BWR with an Advanced Recycle System) has been proposed as a future fuel cycle option aiming at enhanced utilization of uranium resources and reduction of radioactive wastes. In BARS, the spent fuel from conventional light water reactors (LWRs) is recycled as a mixed oxide (MOX) fuel for a BWR core with the fast neutron spectrum by means of oxide dry-processing and vibro-packing fuel fabrication. The fast neutron spectrum is obtained by means of triangular tight fuel lattice. Further study on BARS, especially on tight lattice MOX fuel, has been initiated as a joint study by Toshiba and Gifu University. The objective of this paper is to show the latest progress of the study on BARS, especially concerning the thermal-hydraulics measurements for tight lattice bundle.

    In Poland the radioactive contamination of the environment and food has been controlled since the early sixties by the Service for Measurements of Radioactive Contamination (SPSP). The service comprises a network of measuring stations and the Centre of Radioactive Contamination Measurements (COPSP). Actually, there are 100 measurement stations. The main task of such station is systematic measurement of radioactivity level in samples of environment components and food. Nine stations of SPSP acting within meteorological stations, ten stations of low level air radioactivity measurements (Aerosols Sampling Stations-500) and eleven permanent monitoring stations (PMS) form the radiation monitoring warning system in Poland.

    Full Text Available Gypsophila perfoliata L. is a maritime sand-dune species naturally occurring in Asia and southeastern Europe. In Europe it also is found in ruderal habitats rarely, mainly along railway lines. In Poland the species was first recorded in the 1950s; it was found only at railway stations where iron ore was offloaded from the Kryvyi Rih region, Ukraine. Recently it was found in a new type of habitat: the roadside of a main road in the Carpathians. The paper characterizes the current status, distribution and habitat spectrum of this alien species in Poland.

    The aim of this study is to present the epidemiology of salmonellosis in Poland in 2010. The study was based on data from: "the Infectious diseases and poisonings in Poland 2010", information from laboratories based in sanitary stations, the forms of outbreaks investigations conducted by sanitary stations and data from Demographic Surveys Departament based in the Central Statistical Office. All cases were classified according to the case definition used by surveillance. A total of9 732 salmonellosis cases were reported in Poland. Among them 8 549 cases were intestinal and 183 were extraintestinal. The incidence rate was 25.5 per 100 000 inhabitants. Over 95% of cases met the criteria for a confirmed case. The number of registered cases was higher than in the previous two years, despite this an overall decreasing trend was observed in the number of cases of salmonellosis in Poland. Cases of salmonellosis occurred primarily among children under 5-years old. There were no deaths reported due to salmonellosis. There is still a high percentage, about 70%, hospital admissions of people infected with zoonotic Salmonella. The percentage of hospitalization in outbreaks is almost two and a half times lower -29%. In 2010, 189 outbreaks caused by Salmonella were reported, affecting 1 662 people (almost 18% of all reported cases of intestinal salmonellosis). Most were small family outbreaks. Still the most common etiologic agent in Poland is S. Enteritidis. When compared with previous years, in 2010 there was an increase in the number of cases caused by S. Mbandaka, S. Infantis and S. Virchow. The number of screening tests for carriers among food handlers decreased by over 10% however the percentage diagnosed with positive result increased from 0.3% to 0.5%. Human salmonellosis is still a significant public health problem in Poland. The very high percentage (70%) of hospitalization, persisting for many years indicates that diagnosis and reporting ofsalmonellosis in Poland is

    2018-03-01

    The potential for innovativeness is difficult to measure, though many have attempted to do so. In order to look at Poland's innovation potential, its current position and its opportunity to grow, compared with developing and developed countries, this study analysed the patent statistics of the Polish and European Patent Offices. Poland has been a member of the European Union for over a decade now. Therefore, we took into consideration the statistics for patent applications and grants for the last decade, up to the first quarter of 2016. The questions we wanted to answer concerned not only the technology fields that Poland patented its inventions in, but also the types of patent grantees and applicants. In order to determine why Poland is still considered to be only a moderate innovator by the Innovation Union Scoreboard, we also gathered information on Polish inventors abroad in 2015 and the first quarter of 2016, to see their number, technology fields, and types of patent grantees. Finally, we attempted to identify the main barriers that seem to inhibit Polish technology and innovation growth, despite significantly growing R&D intensities (up from 0.56 GDP and EUR 1,139 M in 2004 to 0.94 GDP and EUR 3,864 M in 2014).

  20. Air protection strategy in Poland

    Energy Technology Data Exchange (ETDEWEB)

    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.

    Since 1998, Poland has been actively participating in the Measles Elimination Program, coordinated by the World Health Organization (WHO). It requires achieving and maintaining very high vaccine coverage (>95%), recording all cases and suspected cases of measles, and laboratory testing of all suspected measles cases in the WHO Reference Laboratory. In Poland it is a Laboratory of Department of Virology, NIPH-NIH.

    Since 1998, Poland has been actively participating in the Measles Elimination Program, coordinated by the World Health Organization (WHO). It requires achieving and maintaining very high vaccine coverage (>95%), recording all cases and suspected cases of measles, and laboratory testing of all suspected measles cases in the WHO Reference Laboratory. In Poland it is a Laboratory of Department of Virology, NIPHNIH. In order to confirm or exclude the case of measles specific measles IgM antibodies should be measured using Elisa test, or molecular testing (PCR) should be performed to detect the presence measles virus RNA in biological material. To assess epidemiological situation of measles in Poland in 2014, including vaccination coverage in Polish population, and Measles Elimination Program implementation status. The descriptive analysis was based on data retrieved from routine mandatory surveillance system, measles case-based reports from 2014 sent to the Department of Epidemiology NIPH-NIH by Sanitary-Epidemiological Stations and data published in the annual bulletins “Infectious diseases and poisonings in Poland in 2014” and “Vaccinations in Poland in 2014” (MP Czarkowski et all., Warszawa 2015, NIZP-PZH, GIS). In total, there were 110 measles cases registered in Poland in 2014 (incidence 0.29 per 100,000), from which 87 cases (79%) were confirmed with laboratory test. That was more than in 2013 - when 84 cases were reported and incidence was 0,22. The highest incidence rate was observed among children aged 1 year (3,43 per 100,000). In 2014, 76 cases (69%) were hospitalized due to measles. No deaths from measles were reported. Vaccination coverage of children and youth aged 2-11 years ranged from 79.7% do 94.8% (primary vaccination in children born in 2004-2013) and from 77.7% to 85.8% (booster dose in children born in 2005-2011).

    In Poland, they are still recorded high number of cases whooping cough - five-year median for 2005-2009 and 2010-2014 are similar and amount to 5.2 and 5.5 per 100 000 population. The trend of the incidence of pertussis in a high percentage of adults that was observed in years between 2009-2011 (the results of the National Research Epidemiology of Pertussis), in subsequent years, ie. 2012-2014 was halted. Still the most effective strategy to prevent illness is the vaccination according to the current vaccination calendar. The aim of the study is to assess the epidemiological situation of pertussis in Poland in 2014, including vaccine coverage of children. Assessment of the epidemiology of pertussis in Poland was based on analysis of individual reports of suspected cases of pertussis sent to the NIPH-NIH by the regional sanitaryepidemiological stations, data from the bulletin “Infectious diseases and poisonings in Poland in 2011” and bulletin “Immunizations in Poland in 2014 “ (MP Czarkowski et al, Warsaw 2015, NIPH-NIH, GIS). In 2014, number of registered cases of whooping cough was 2 100. The incidence was 5.5 per 100,000 and it was slightly lower than in the previous year (5.5/100,000). The highest incidence (46%) occurred in children aged 15 years and older. 601 people were hospitalised (28.6% of total). In 2014, there were no deaths from whooping cough. The incidence of whooping cough observed in 2014 is comparable to the previous year and it indicates a fixed circulation of bacteria in the environment and still continuing infection vulnerability of the population.

    2015-01-01

    The purpose of the study was to evaluate the epidemiologic situation of salmonellosis in Poland in 2013 compared to previous years. The main source of data for this study are statistical overviews included in annual bulletin "Infectious Diseases in Poland in 2013", information from sanitary station laboratories as well as forms of outbreak investigations obtained from the sanitary stations. Information on deaths due to infectious and parasitic diseases registered in Poland in 2013 and earlier years is based on the data of the Department for Demographic Research of Central Statistical Office. For the purpose of surveillance cases were qualified according to the current definition. In Poland in 2013, a total of 7 578 cases of zoonotic salmonellosis were reported including 7 407 cases of intestinal salmonellosis and 171 of parenteral one. The incidence was 19,7/100 000. The criteria for a confirmed case were met by more than 96% of cases. The number of reported cases was lower than in previous year, reflecting the continued downward trend in the number of cases of salmonellosis in Poland. A very high percentage (more than 72%) of hospitalizations of people infected with zoonotic Salmonella continues. In the outbreaks the proportion of hospitalizations accounted only for 35% of all cases. Predominantly children below 5 years of age suffer from the illness. Salmonellosis was an indicated cause of death only in 10 of the cases. In 2013 179 outbreaks were reported, in which Salmonella was found to be the etiological agent. Majority of them were small household outbreaks and they cumulated for a total number of cases of 1 218. The most common species of Salmonella responsible for infection in Poland is S. Enteritidis. For many years, up to date a slight increase is observed in reported cases of the disease, but without known serotype of Salmonella. In 2013 it was 16% and (as in previous year) it was the highest in pomorskie voivodeship (58%). High percentage of

    1999-01-01

    High level radioactive wastes and timing gas generation means for jetting out an inert gas after a predetermined period of time are contained together in a steel overpack. A steel lid is welded to the opening of the overpack so as to seal the high level radioactive wastes and the timing gas generation means. Then, the inert gas is jetted out from the timing gas generating device, and the gas tightness is detected by detecting the inert gas at the circumference of the overpack. Alternatively, a corrosion resistant coating layer having a gas generation means for jetting out an inert gas is coated at the circumference of a steel overpack containing high level radioactive wastes, and the overpack is sealed. The inert gas is generated from the gas generating means in the coating layer, and the inert gas at the periphery of the coating layer is detected to determine gas tightness. (N.H.)

    The aim of this study was to assess the epidemiology of meningitis and/or encephalitis in Poland in 2014. In the last three years in Poland, about 3000 cases of meningitis and/or encephalitis of viral or bacterial etiology were recorded annually. Assessment of the epidemiological situation of meningitis and/or encephalitis in Poland in 2014, was based on the results of the analysis of epidemiological reports sent to the NIZP-PZH by the Regional Sanitary-Epidemiological Stations published in the annual bulletin “Infectious diseases and poisonings in Poland in 2014” and “Preventive immunizations in Poland in 2014”. In 2014 in Poland 3488 cases of bacterial meningitis and/or encephalitis were recorded. Almost 61.3% of these were viral infections. In 2014, in comparison to 2013, a 1.1% increase in the number of cases of meningitis and/or encephalitis was observed and 91% with viral etiology.

    Poland syndrome was first described in 1840 by Alfred Poland while still a medical student and the other components of the syndrome were described at London Guy's Hospital following the dissection of a cadaver's hand, which had hypoplasia and syndactyly. The incidence of Poland syndrome has been reported to be 1 in 30,000 live births. In the present case report, two Poland syndrome patients with ipsilateral hypomastia and a reduction in the axillary/pectoral hairs diagnosed during adulthood are presented; one patient was affected on the left side and had widespread cafe au lait spots, and the other patient had respiratory dysfunction due to multiple rib anomalies.

  14. The role of tight junctions in mammary gland function.

    Stelwagen, Kerst; Singh, Kuljeet

    2014-03-01

    Tight junctions (TJ) are cellular structures that facilitate cell-cell communication and are important in maintaining the three-dimensional structure of epithelia. It is only during the last two decades that the molecular make-up of TJ is becoming unravelled, with two major transmembrane-spanning structural protein families, called occludin and claudins, being the true constituents of the TJ. These TJ proteins are linked via specific scaffolding proteins to the cell's cytoskeleton. In the mammary gland TJ between adjacent secretory epithelial cells are formed during lactogenesis and are instrumental in establishing and maintaining milk synthesis and secretion, whereas TJ integrity is compromised during mammary involution and also as result of mastitis and periods of mammary inflamation (including mastitis). They prevent the paracellular transport of ions and small molecules between the blood and milk compartments. Formation of intact TJ at the start of lactation is important for the establishment of the lactation. Conversely, loss of TJ integrity has been linked to reduced milk secretion and mammary function and increased paracellular transport of blood components into the milk and vice versa. In addition to acting as a paracellular barrier, the TJ is increasingly linked to playing an active role in intracellular signalling. This review focusses on the role of TJ in mammary function of the normal, non-malignant mammary gland, predominantly in ruminants, the major dairy producing species.

    Full Text Available We give a tight scheme for teleporting a quantum state between two parties whose reference frames are misaligned by an action of a finite symmetry group. Unlike previously proposed schemes, ours requires no additional tokens or data to be passed between the participants; the same amount of classical information is transferred as for ordinary quantum teleportation, and the Hilbert space of the entangled resource is of the same size. In the terminology of Peres and Scudo, our protocol relies on classical communication of unspeakable information.

    Full Text Available A combination of local flow measurement techniques and fog flow visualization was used to determine the inward leakage for two tight-fitting powered air-purifying respirators (PAPRs, the 3M Breathe-Easy PAPR and the SE 400 breathing demand PAPR. The PAPRs were mounted on a breathing machine head form, and flows were measured from the blower and into the breathing machine. Both respirators leaked a little at the beginning of inhalation, probably through their exhalation valves. In both cases, the leakage was not enough for fog to appear at the mouth of the head form.

    2014-12-01

    Full Text Available The author discusses issues of sustainable development in rural areas in Poland from the perspective of natural resources management. Sustainable development of rural areas is the way of managing which links economic, social and ethical principles with ecological safety. This may be reached by proper management, directed on cautious usage of ecosystems’ self-controlling mechanisms, with the progress of science and technology. Agriculture in Poland is one of the most important sectors from an economic perspective and its importance is greater in Poland than in other countries in the EU. It has an influence not only on the social and economic situation of the rural population, but also on the natural environment, structure of landscape and biodiversity. From ecological point of view, functions of rural areas are not only being a place for production of food, resources for industry and green energy, but also supplying environmental goods such as protection of biodiversity and influencing air and water quality as well as landscape. The author presents ways to reduce the pressure of agricultural activities on water resources in the region, catchment and farm scale

    2010-04-01

    In vitro studies have demonstrated that occludin and tricellulin are important for tight junction barrier function, but in vivo data suggest that loss of these proteins can be overcome. The presence of a heretofore unknown, yet related, protein could explain these observations. Here, we report marvelD3, a novel tight junction protein that, like occludin and tricellulin, contains a conserved four-transmembrane MARVEL (MAL and related proteins for vesicle trafficking and membrane link) domain. Phylogenetic tree reconstruction; analysis of RNA and protein tissue distribution; immunofluorescent and electron microscopic examination of subcellular localization; characterization of intracellular trafficking, protein interactions, dynamic behavior, and siRNA knockdown effects; and description of remodeling after in vivo immune activation show that marvelD3, occludin, and tricellulin have distinct but overlapping functions at the tight junction. Although marvelD3 is able to partially compensate for occludin or tricellulin loss, it cannot fully restore function. We conclude that marvelD3, occludin, and tricellulin define the tight junction-associated MARVEL protein family. The data further suggest that these proteins are best considered as a group with both redundant and unique contributions to epithelial function and tight junction regulation.

    The work plan for October 1, 1997 to September 30, 1998 consisted of investigation of a number of topical areas. These topical areas were reported in four quarterly status reports, which were submitted to DOE earlier. These topical areas are reviewed in this volume. The topical areas covered during the year were: (1) Development of preliminary tests of a production method for determining areas of natural fracturing. Advanced Resources has demonstrated that such a relationship exists in the southern Piceance basin tight gas play. Natural fracture clusters are genetically related to stress concentrations (also called stress perturbations) associated with local deformation such a faulting. The mechanical explanation of this phenomenon is that deformation generally initiates at regions where the local stress field is elevated beyond the regional. (2) Regional structural and geologic analysis of the Greater Green River Basin (GGRB). Application of techniques developed and demonstrated during earlier phases of the project for sweet-spot delineation were demonstrated in a relatively new and underexplored play: tight gas from continuous-typeUpper Cretaceous reservoirs of the Greater Green River Basin (GGRB). The effort included data acquisition/processing, base map generation, geophysical and remote sensing analysis and the integration of these data and analyses. (3) Examination of the Table Rock field area in the northern Washakie Basin of the Greater Green River Basin. This effort was performed in support of Union Pacific Resources- and DOE-planned horizontal drilling efforts. The effort comprised acquisition of necessary seismic data and depth-conversion, mapping of major fault geometry, and analysis of displacement vectors, and the development of the natural fracture prediction.

    The U.S. Internal Revenue Service on Apr. 1, 1991, released the inflation adjustments used in the calculations of Non-Conventional Fuel Tax Credits for 1990. The inflation adjustment, 1.6730, when applied to the base price of $3/bbl of oil equivalent, adjusts the tax credit to $5.019/bbl for oil and 86.53 cents/MMBTU for gas. The conversion factor for equivalent fuels is 5.8 MMBTU/bbl. Unfortunately, the tax credit for tight formation gas continues to be unadjusted for inflation and remains 52 cents/MMBTU. As many producers are aware, the Omnibus Budget Reconciliation Act of 1990 expanded the dates of eligibility and the usage for-Non-Conventional Fuel Tax Credits. Among other provisions, eligible wells may be placed in service until Jan. 1, 1992, and once in place may utilize the credit for production through Dec. 31, 2002.

Tuberculosis surveillance and monitoring in Europe 2016. Stockholm: European Centre for Disease Prevention and Control, 2016”. 6 698 TB cases were reported in Poland in 2014. The incidence rate was 17.4 cases per 100 000, withlarge variability between voivodeships from 9.3 to 26.5 per 100 000. The mean annual decrease of TB incidence in 2010- 2014 was 2.1%. 6 066 cases had no history of previous treatment i.e. 15.8 per 100 000. 632 cases i.e. 1.6 per 100 000 – 9.4% of all registered subjects were relapses. The number of all notified pulmonary tuberculosis cases in 2014 was 6311 i.e. 16.4 per 100 000. Pulmonary cases represented 94.2% of all TB cases. In the presented year 387 extrapulmonary TB cases were reported. Children with TB (70 cases) accounted for 1.0% of all cases notified in Poland. The incidence of tuberculosis increases with age from 1.2 per 100 000 among children to 30.4 per 100 000 among patients 65 years old and older. The incidence among men i.e. 24.6 per 100 000 was 2.3 times higher than among women i.e. 10.7 per 100 000. The biggest difference in the TB incidence between the two sex groups occurred in persons aged 45 to 49 years – 40.4 vs. 9.3. The TB incidence in rural population was lower than in urban, respectively 17.0 per 100 000 and 17.7 per 100 000. The number of all registered culture positive TB cases, including relapses, was 4

    The objective of this study is to investigate the feasibility of the On-Board Sound Intensity (OBSI) system to measure tire-pavement noise in Poland. In general, sources of noise emitted by the modern vehicles are the propulsion noise, aerodynamic resistance and noise generated at the tire-pavement interface. In order to capture tire-pavement noise, the OBSI system uses a noise intensity probe installed in the close proximity of that interface. In this study, OBSI measurements were performed at different types of pavement surfaces such as stone mastic asphalt (SMA), regular asphalt concrete (HMA) as well as Portland cement concrete (PCC). The influence of several necessary OBSI measurement conditions were recognized as: testing speed, air temperature, tire pressure and tire type. The results of this study demonstrate that the OBSI system is a viable and robust tool that can be used for the quality evaluation of newly built asphalt pavements in Poland. It can be also applied to generate reliable input parameters for the noise propagation models that are used to assess the environmental impact of new and existing highway corridors.

    To evaluate the main features of TB epidemiology in 2012 in Poland and to compare with the corresponding EU data. Analysis of case- based clinical and demographic data on TB patients from Central TB Register, of data submitted by laboratories on anti-TB drug susceptibility testing results in cases notified in 2012, data from National Institute of Public Health - National Institute of Hygiene on cases of tuberculosis as AIDS-defining disease, from Central Statistical Office on deaths from tuberculosis based on death certificates, data from ECDC report "Tuberculosis Surveillance in Europe, 2014 (situation in 2012). 7 542 TB cases were reported in Poland in 2012. The incidence rate was 19.6 cases per 100 000, with large variability between voivodships from 10.6 to 30.2. The mean annual decrease of TB incidence in 2008-2012 was 2.4%. 6 665 cases had no history of previous treatment; 17.3 per 100 000. The number of all notified pulmonary tuberculosis cases was 7 018; 18.2 per 100 000. The proportion of extrapulmonary tuberculosis among all registered cases was 6.9% (524 cases). In 2012, 36 patients had fibrous-cavernous pulmonary tuberculosis (0.5% of all cases of pulmonary tuberculosis). TB was diagnosed in 95 children (1.3% of all cases, incidence 1.6). The incidence of tuberculosis increased progressively with age to 34.8 among patients 65 years old and older. The mean age of new TB cases was 53.1 years. The incidence among men (27.4) was more than two times higher than among women (12.2). The incidence rate in rural population was lower than in urban; 20.2 vs. 18.6. Bacteriologically confirmed pulmonary cases (4870) constituted 69,4% of all pulmonary TB cases. The number of smear positive pulmonary TB cases was 2 778 (39.6% of all pulmonary cases). In 2012 in the all group of TB patients in Poland there were 276 (3.7%) of homeless and 1 905 (25.3%) of unemployed. There were 48 foreigners registered among all cases of tuberculosis in Poland (0.6%) and 243 cases

    2016-12-01

    Full Text Available Data from a number of tourism and transport sources are used in this analysis, concentrating on Poland: the largest tour operators and areas in which air carriers are likely to have the greatest impact. The top 25 air charter carriers identified are examined closely in terms of connections, and the geographical characteristics of these links are highlighted. The research reveals substantial differences in models of air leisure traffic between Western Europe and Poland. These are of a quantitative, but also a qualitative nature, and reflect the disparate levels of affluence of societies, different mobility patterns, and various experiences, adventures and demands on the part of travellers. Overall, charter traffic in Poland is still seen to be flourishing, while that in Western Europe is in relative decline.

    Social capital, measured as the level of trust among people, may be regarded as a new production factor alongside the traditional ones of human and physical capital. With appropriate levels of social capital, monitoring and transaction costs can be saved and thus economic growth stimulated. Via...... linking social capital to rural development and comparing the cases of agricultural cooperative movements in Denmark and Poland, this paper identifies possible roots of building social capital and suggests that social capital was built through a lengthy process in both countries during the 19th century....... However, the comparison of the present level of social capital indicates that the level of social capital is significantly higher in Denmark than in Poland. The paper concludes that the reason for this difference is due to the fact that the original accumulation of social capital in Poland was destroyed...

  13. What Determines State Capture in Poland?

    2013-12-01

    Full Text Available Purpose: This study examines the determinants of ex-ante state capture in Poland. Methodology: In order to establish the determinants of ex-ante state capture a logistic regression is estimated. Findings: The study shows that in Poland the majority of legal acts were passed with the aim to satisfy the interest of particular groups. Furthermore, the regression analysis shows that the likelihood of state capture increases during the period of higher economic growth and local elections. The likelihood of state capture, however, declines during presidential elections. The results we attribute to different interests of political parties in the period of local and presidential elections. Finally, we fi nd that the state capture increased over the years in Poland. Additionally, we show that the EU accession did not prevent state capture in Poland. In contrast, the fi nancial crisis of 2007 resulted in a wake-up effect and the likelihood of state capture declined in Poland. Research limitations: In the study we employ proxies for state capture, yet we assume that corruption is a widespread phenomenon in Poland. However, due to its nature corruption is very diffi cult to assess and measure. Originality: The study uses a unique dataset on ex-ante state capture that was identifi ed in the legal acts that have been passed in the period 1990–2011 in Poland.

    Poland started the works on construction of first nuclear power plant in 1992. The social protest as well as deep political and economical changes in Poland induced the decision of the Polish government to abandon the construction of the nuclear power plant in Zarnowiec. After the period of political and economical transformation, in 1992 Polish economy starts to grow up, also growth of the electric power consumption. Are there prospect for utilization in Poland the nuclear power plant? This work is devoted to analyse such question. The present structure of power and fuel materials in Poland were analysed and the possible direction of changes was shown for the period up to 2020 year. It was stated, that the economical development in Poland should be bound with the growth of the consumption of most effective fuel and energy. These fuel or energy should be imported to Poland. Therefore, the nuclear power should be treated as one of possible ways of the balance of electric power in Poland. Particularly, that it will be expected the special ecological conditions in the energy production in Europe. In the present work, was shown, that the nuclear power was discriminated in the analysis of the development of power and fuel system in Poland. The incorrect values of economical parameters concerning of the nuclear power plant was used in the analysing numerical programs. The investment costs, design time and fuel price for nuclear energy was analysed, and shown, that in the proper conditions, the cost of the electric energy produced in the nuclear power plant is compared with the costs of electric energy produced in the conventional power stations. In this work, the proposals of the basic nuclear and radiological safety standards for the nuclear power plant in Poland are shown. (author). 20 refs, 10 figs, 3 tabs

    In contrast to animals, Crimean-Congo hemorrhagic fever (CCHF) causes a severe disease in humans with a high mortality rate. The etiological agent, CCHF virus (CCHFV), can be transmitted by argasid and ixodid ticks, but arachnids of the genus Hyalomma, followed by Rhipicephalus and Dermacentor serve as the major vectors of this virus. The goal of the study was to assess the epidemiological situation of CCHFV infection in cattle in south-east Poland, and survey for potential tick vector species. A total of 592 bovine blood samples from animals located in the southernmost region in Poland were tested by IgG sandwich enzyme-linked immunosorbent assay. Ticks (n = 993) from south-east Poland were collected from dogs, cats, cattle, and horses and tested by RT-PCR. All 592 serum samples were negative for IgG antibodies to CCHFV. Of the ticks collected, 125 were Dermacentor reticulatus and 868 represented Ixodes ricinus, both species are regarded as potential vectors of CCHFV. All tick samples were negative for the presence of CCHFV. Considering the zoonotic nature, public health importance, and the virus increasing spread, it was prudent to assess the seroprevalence of CCHFV in the south-east area of Poland, bordering with CCHFV endemic areas. It seems unlikely that CCHFV infection will suddenly spread in Poland, but considering the multiple possibilities of the virus introduction, serosurveys and vector biosurveillance should be conducted at regular intervals.

    Sadkowska-Todys, Małgorzata; Czarkowski, Mirosław P

    The aim of the study is to assess the epidemiological situation of salmonellosis in Poland in 2014 in comparison to the previous years. The evaluation was based on the data from the bulletin “Infectious diseases and poisoning in Poland 2014”, information from the laboratories of sanitary-epidemiological stations and reports from the epidemiological investigations in outbreaks of salmonellosis, sent by the sanitary-epidemiological stations to the Department of Epidemiology, as well as the data from the Department of Demographic Studies of the Central Statistical Office. Cases were classified according to the definitions adopted in the UE. In 2014, a total number of 8 392 cases of salmonellosis derived from animals were reported, including 8 197 cases of intestinal salmonellosis and 195 cases of extraintestinal. The total incidence was 21.8/100 000. Almost 96% of the cases met the criteria for a confirmed case. The number of registered cases was, for the first time since many years, higher than in the previous year, but still lower than the median for 2008-2012. A very high percentage (approximately 70%) of hospitalizations remains among patients diagnosed with salmonellosis. Approximately 33% of all cases in outbreaks of salmonellosis were hospitalized. The highest incidence was among children under the age of 5 years. Salmonellosis was reported as the cause of death for 13 patients. In 2014 there were 171 outbreaks reported with Salmonella as an etiological agent. Majority of them were small outbreaks limited to the family in singular household, and the total number of cases in those outbreaks amounted to 1 229 people. In Poland the most common etiological agent of salmonellosis is (and have been for many years) S. Enteritidis. In 2014, the first time in many years, an increase was recorded in the annual number of cases of salmonellosis. A very high percentage of hospitalizations for salmonellosis cases indicates a relatively rare practice among GPs in ordering

    2008-06-01

    Full Text Available This paper presents spatial relations between Polish urban areas and valuable habitats and links between them composing the country’s ecological network. The quantitative analysis for 891 towns and cities was conducted using GIS techniques based on cartographic vector data and statistical data. Valuable habitats and links between them, such as national parks, landscape parks, CORINE biotopes sites, wildlife corridors linking NATURA 2000 sites and ECONET areas, can be found in 72% of Polish towns and cities. The proportion of artificial surfaces in those areas is different depending on the size of a town or city and its location. Urban areas with the highest index of presence of valuable habitats and links between them are concentrated in the south of Poland, where settlement network is most dense. However, in the case of those areas the proportion of artificial surfaces interfering with the ecological network is lower than Poland’s average, being 16%. The pressure of anthropogenic land cover extending onto the country’s ecological network is most conspicuous in urban areas with a population of at least several dozen thousand residents where the average developed area is 20.8% of their total area. The danger for the continuity of the nature system is best seen in the north westernPoland, where artificial surfaces interference in towns and cities is largest. The analysis performed identified 82 towns and cities, in which the preservation of the continuity of the ecological networkshould be a priority in spatial management because of a higher than average index of the presence of valuable habitats and links between them and large proportion of artificial surfaces in those areas.

  19. Uncooled infrared photodetectors in Poland

    2006-03-01

    The history and present status of the middle and long wavelength Hg1-xCdxTe 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 vapour 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 vapour 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. At present, 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.

    2015-12-01

    According to the Directive 2009/28/EC of the European Parliament and of the European Council on the promotion of the use of energy from renewable sources the target for the share of energy from renewable sources in gross final energy consumption in the year 2020 for Poland is 15%. Poland promotes renewable electricity through a quota system, tax relief and subsidies, as well as loans. There are three subsidy models and a loan scheme, which support heat generated from renewable energy sources. In dimension to transport renewable energy is promoted primarily by bio-fuels. The Republic of Poland established two programmes for renewable energy plants: a training programme, which is dedicated to installers in RES sector and certification system pertaining solar thermal installations. This report monitors the policy changes after the release of the 2013 Progress Report for Poland and was regularly updated (updated until December 2015)

  4. Identification of MarvelD3 as a tight junction-associated transmembrane protein of the occludin family

    Directory of Open Access Journals (Sweden)

    Balda Maria S

    2009-12-01

    Full Text Available Abstract Background Tight junctions are an intercellular adhesion complex of epithelial and endothelial cells, and form a paracellular barrier that restricts the diffusion of solutes on the basis of size and charge. Tight junctions are formed by multiprotein complexes containing cytosolic and transmembrane proteins. How these components work together to form functional tight junctions is still not well understood and will require a complete understanding of the molecular composition of the junction. Results Here we identify a new transmembrane component of tight junctions: MarvelD3, a four-span transmembrane protein. Its predicted transmembrane helices form a Marvel (MAL and related proteins for vesicle traffic and membrane link domain, a structural motif originally discovered in proteins involved in membrane apposition and fusion events, such as the tight junction proteins occludin and tricellulin. In mammals, MarvelD3 is expressed as two alternatively spliced isoforms. Both isoforms exhibit a broad tissue distribution and are expressed by different types of epithelial as well as endothelial cells. MarvelD3 co-localises with occludin at tight junctions in intestinal and corneal epithelial cells. RNA interference experiments in Caco-2 cells indicate that normal MarvelD3 expression is not required for the formation of functional tight junctions but depletion results in monolayers with increased transepithelial electrical resistance. Conclusions Our data indicate that MarvelD3 is a third member of the tight junction-associated occludin family of transmembrane proteins. Similar to occludin, normal expression of MarvelD3 is not essential for the formation of functional tight junctions. However, MarvelD3 functions as a determinant of epithelial paracellular permeability properties.

    Silin, Dmitriy [Lawrence Berkeley National Lab. (LBNL), Berkeley, CA (United States)

    2012-08-07

    This technical report summarizes some recently developed approaches to studies of rock properties at a pore scale. Digital rock approach is complementary to laboratory and field studies. It can be especially helpful in situations where experimental data are uncertain, or are difficult or impossible to obtain. Digitized binary images of the pore geometries of natural rocks obtained by different imaging techniques are the input data. Computer-generated models of natural rocks can be used instead of images in a case where microtomography data are unavailable, or the resolution of the tools is insufficient to adequately characterize the features of interest. Simulations of creeping viscous flow in pores produce estimates of Darcy permeability. Maximal Inscribed Spheres calculations estimate two-phase fluid distribution in capillary equilibrium. A combination of both produce relative permeability curves. Computer-generated rock models were employed to study two-phase properties of fractured rocks, or tight sands with slit-like pores, too narrow to be characterized with micro-tomography. Various scenarios can simulate different fluid displacement mechanisms, from piston-like drainage to liquid dropout at the dew point. A finite differences discretization of Stokes equation is developed to simulate flow in the pore space of natural rocks. The numerical schemes are capable to handle both no-slip and slippage flows. An upscaling procedure estimates the permeability by subsampling a large data set. Capillary equilibrium and capillary pressure curves are efficiently estimated with the method of maximal inscribed spheres both an arbitrary contact angle. The algorithms can handle gigobytes of data on a desktop workstation. Customized QuickHull algorithms model natural rocks. Capillary pressure curves evaluated from computer-generated images mimic those obtained for microtomography data.

  6. US production of natural gas from tight reservoirs

    International Nuclear Information System (INIS)

    1993-01-01

    For the purposes of this report, tight gas reservoirs are defined as those that meet the Federal Energy Regulatory Commission's (FERC) definition of tight. They are generally characterized by an average reservoir rock permeability to gas of 0.1 millidarcy or less and, absent artificial stimulation of production, by production rates that do not exceed 5 barrels of oil per day and certain specified daily volumes of gas which increase with the depth of the reservoir. All of the statistics presented in this report pertain to wells that have been classified, from 1978 through 1991, as tight according to the FERC; i.e., they are ''legally tight'' reservoirs. Additional production from ''geologically tight'' reservoirs that have not been classified tight according to the FERC rules has been excluded. This category includes all producing wells drilled into legally designated tight gas reservoirs prior to 1978 and all producing wells drilled into physically tight gas reservoirs that have not been designated legally tight. Therefore, all gas production referenced herein is eligible for the Section 29 tax credit. Although the qualification period for the credit expired at the end of 1992, wells that were spudded (began to be drilled) between 1978 and May 1988, and from November 5, 1990, through year end 1992, are eligible for the tax credit for a subsequent period of 10 years. This report updates the EIA's tight gas production information through 1991 and considers further the history and effect on tight gas production of the Federal Government's regulatory and tax policy actions. It also provides some high points of the geologic background needed to understand the nature and location of low-permeability reservoirs

  7. Energy Policies of IEA Countries: Poland [Polish version

    Energy Technology Data Exchange (ETDEWEB)

    NONE

    2011-07-01

    Poland has made commendable efforts to develop a solid energy policy framework over the last years. As energy security is a high policy priority, the country is enhancing gas supply security by building an LNG terminal, expanding underground storage capacity and increasing domestic gas production. Polish plans for developing electricity and gas cross-border links will also contribute to regional security of supply. In addition, the government has announced an ambitious nuclear programme by 2030, envisaging the first unit to enter operation by 2022. Other achievements include energy intensity improvements, an increased share of renewables and a stronger focus on energy research and development (R&D). Despite these positive developments, there is room for improving Poland’s energy strategy. First, a more integrated energy and climate policy is needed to put Poland firmly on a low-carbon path while enhancing energy security. Second, energy policy could put more emphasis on promoting competition to make the energy markets more efficient. Decarbonising Poland’s power sector will be a particularly significant challenge requiring huge investments. Coal accounts for 55% of Polish primary energy supply and 92% of electricity generation, raising significant climate change and environmental challenges. To this end, Poland’s efforts to improve energy efficiency and to diversify the country’s energy mix are praiseworthy and should be pursued. The government’s attention to R&D on clean coal technologies, including carbon capture and storage (CCS) is also encouraging. The government could put more focus on the positive role that gas can play in decarbonising the electricity mix, especially if Poland’s potential resources of unconventional gas are confirmed. To tap these resources, it will be vital to put the necessary legal and regulatory framework in place. This in-depth review analyses the energy challenges facing Poland and provides sectoral critiques and

    Epidemiological assessment of the incidence of tetanus in Poland in 2010 was based on the analysis of aggregate data provided by the State Sanitary Inspection and published an annual newsletter: Infectious diseases and intoxications in Poland in 2010, compiled by MP Czarkowski, E Cielebak, B Kondej, E Staszewska, Warsaw in 2011 and based on an annual newsletter: Vaccinations in Poland in 2010, compiled by MP Czarkowski, E Cielebak, B Kondej, E Staszewska, Warsaw 2011. A more accurate characterization of disease was based on the individual reports sent to the Department of Epidemiology, NIPH-NIH. In the last decade the incidence of tetanus has remained below 0.08/100 000 inhabitants. The average annual incidence was lower than in the previous decade, but within the last ten years to the annual variation is difficult to assign a distinct incidence tendency. Rather, they correspond to random fluctuations. In 2010, 16 cases were reported, including which occurred in 2009. All cases was reported as probable--diagnosis based on clinical signs and information about injuries. Overall incidence was 0.042/100 000, which was small and not significanty different from incidence in 2009 (0.05/100 000). All cases in 2010, were over 59 years of age, which is a strong expression of the trend observed for years that the disease is present in older age groups where the level of vaccination against tetanus is particularly low. Among people infected, there were three men and 13 women. Four cases ended with deaths. Three of these were women, among whom mortality was 23.1%, and one death occurred in a man, mortality 33.3%. Three deaths occurred among the 6 cases in people over 79 years of age, mortality 50%. The incubation period of the disease in 3 cases was less than 7 days, in 4 cases 8-14 days, in 4 cases 15-21 days, in 2 cases 22 days and more. Portals of entry of infection in 7 cases accounted for abrasion or laceration, in 6 cases the puncture wound in one it was bitten wound, and

    Polański, Piotr

    The aim of this article is to assess the epidemiological situation of hepatitis A in Poland in 2014 with the regard to the recent years. The assessment was conducted based on the results of the analysis of data from the bulletins “Infectious diseases and poisonings in Poland in 2014” and “Vaccinations in Poland in 2014”, as well as information from the individual cases questionnaires and reports of epidemiological investigations in outbreaks of hepatitis A, submitted by the sanitary-epidemiological stations to the Department of Epidemiology in NIPH-NIH. In 2014 in Poland there were 76 cases of hepatitis A registered. Incidence per 100 000 inhabitants was 0.20, and in different voivodeships varied from 0.07 (in Dolnosląskie voivodeship) to 0.30 (in Małopolskie voivodeship). The incidence among male and female did not differ (and was 0.20/ 100 000). In 2014 despite the increase in the number of cases (comparing it to the previous year) no significant change in epidemiological situation of hepatitis A was observed. Poland is still regarded as a country of low endemicity of hepatitis A. In routine surveillance system there is no information concerning the professional affiliation of persons being vaccinated, whereas the vaccinations themselves are recommended in the Polish vaccination schedule. Particular attention should be directed towards the vaccinations of persons who take part in berries primal production, product of which Poland is a major exporter of in the EU. In the light of increasing number of international hepatitis A outbreaks (which could be characterized by the prolonged duration, as well as the high possibility of secondary cases appearing- especially in countries of low endemicity) the maintenance of high level routine surveillance in Poland gains importance. The latter could also contribute to the efficiency of epidemiological investigations in multistate outbreaks.

    In Poland registration of all cases of Lyme disease is conducted by the Epidemiological Unit of National Institute of Public Health - National Institute of Hygiene. Most cases of Lyme disease occur in the North- East region of Poland; however, it is important to note that the disease is no longer solely a problem of this region of Poland. The aim of this work is to assess the epidemiological situation of Lyme disease in Poland in 2012 as compared to the situation in the previous years. Assessment of the epidemiological situation of Lyme disease in Poland was made on the basis of an analysis of individual notifications of suspected Lyme disease submitted to NIZP-NIH by the Provincial Sanitary- Epidemiological Stations; as well as data from "Infectious diseases and poisoning in Poland in 2012" bulletin, and "Vaccinations in Poland in 2012" bulletin (MP Czarkowski and Co, Warsaw 2013, NIPH-NIH, NCI). In 2012 there were 8 782 registered cases of Lyme disease and it is 4.3% higher than in the previous year. The overall incidence in the country amounted to 23.8 per 100 000 people. The highest incidence rate was recorded in Podlaskie province - 75.5 per 100 000 people. 2 063 people were hospitalized due to Lyme disease. In 2012 incidence rate of Lyme disease was gradually dropping down. The registered number of cases was reduced by 4.1% in comparison to the previous year. There is still a fairly low percentage of cases detected with diagnostic test called Western blot method.

    2016-01-01

    Full Text Available Key factors influencing electricity consumption in the residential sector in Poland have been identified. A fixed-effects model was used, which includes time effects, and a set of covariates, based on the model developed by Houthakker et al. This model estimates electricity demand by using lagged values of the dependent variable along with current and lagged values of electricity prices, and other variables that affect electricity demand such as: population, economic growth, income per capita, price of related goods, etc. The model has been identified according to the research results of the authors and those obtained by Bentzen and Engsted. The set of covariates was extended to the lagged electricity price given by a tariff (taken from two years previous to the time of interest and heating degree days index, a very important factor in European Union countries, where the climate is temperate. The authors propose four models of residential electricity demand, for which a confidence interval of 95% has been assumed. Estimation was based on Polish quarterly data for the years 2003-2013.

    Celiński-Mysław, Daniel; Matuszko, Dorota

    2014-11-01

    The paper analyses six cases of the derecho phenomena, which occurred in Poland between 2007 and 2012. The input data included reports on dangerous meteorological phenomena, SYNOP and METAR reports, MSL pressure maps, upper air maps at 500 hPa and 850 hPa, radar depictions and satellite images, upper air sounding plots and data from a system locating atmospheric discharges. Derechos are caused directly by the activity of mesoscale convective systems linked up with either, in winter, a cold front of a deep low-pressure system, or, in summer, with an area of wind convergence in a warm sector of a cyclone or with an articulated cold front which, moving within a low-pressure embayment, develops a very active secondary depression. It was found that southern and central Poland were the regions most frequently affected by derechos. Mid-level and high-level jet streams, augmented by high thermodynamic instability of air masses, were found to be conducive to the development of derechos.

  15. Environmental aspects of the geothermal energy utilisation in Poland

    2017-11-01

    Geothermal energy is considered as a strategic and sustainable source of renewable energy that can be effectively managed in several economic sectors. In Poland, despite the abundant potential of such resources, its share in the energy mix of renewable energy sources remains insubstantial. The utilisation of geothermal resources in Poland is related to the hydrogeothermal resources, however, numerous researches related to petrogeothermal energy resources are being performed. The utilisation of each type of energy, including geothermal, has an impact on the natural environment. In case of the effective development of geothermal energy resources, many environmental benefits are pointed out. The primary one is the extraction of clean, green energy that is characterised by the zero-emission rate of pollutants into the atmosphere, what considering the current environmental pollution in many Polish cities remains the extremely important issue. On the other hand, the utilisation of geothermal energy might influence the natural environment negatively. Beginning from the phase of drilling, which strongly interferes with the local landscape or acoustic climate, to the stage of energy exploitation. It should be noted that the efficient and sustainable use of geothermal energy resources is closely linked with the current law regulations at national and European level.

    2014-01-01

    Full Text Available Over the last quarter of the century relations between Russia and Poland are balancing between trying to understand the burden of mutual guilt and a desire to construct non-emotional pragmatic relations. Sources of tension vary. In particular, it is the desire of Poland to position itself as a valued player in NATO and the EU and the role distance between the two countries in IR system, which does not allow Russia to maintain an equal political dialogue with Poland. In fact, Poland is not afraid of a direct threat from Russia, but the worst scenario is the one in which Russia without changing the content of its imperial policy can be accepted as a full partner in the international community. The evolution of Russian statehood and national specifics of democracy is largely determined the assessment of the prospects of Russian politics in Poland. The mistake of Polish diplomacy last years was that it took no direct efforts to improve relations with Russia, but only tried to impose the dialogue on Russian authorities. Diplomatic methods were designed to hurt Russian interests and to create a topic for discussion. In response, after 2006 Russia chose the tactic of ignoring Poland. But, ignoring Polish authorities, Russian politicians acted similarly with other political forces. In Poland among influential political forces, there was and there is still no loyalty to Russia. For Russian interests it is no matter who are or will be in power in Poland. However as a rule, it is an important factor that foreign policy decisions are de facto within the competences of the President and the government, as well as experiencing a significant influence of the parliamentary forces. Recent trends show no tangible innovations in bilateral programme. But innovations appear in multilateral and conflict enough issues, such as deployment of US missile defense system in Poland or Polish supervision of "Eastern Partnership" programme.

    2014-06-01

    Full Text Available In Poland, inland shipping plays only a mariginal role in transport needs fulfillment. Inland shipping has a share of mere 0,3% in goods transport modal split. The reason for this is poor and variable technical parameters of inland waterways together with adverse legal regulations. Different situation takes place in Western European countries, in which the development of this mode of transport is viewed as a way of road transport develop-ment restraint. In Poland, the need to move some of the volume from road transport to in-land shipping is specifically observed within marine ports surroundings. Because of their complex nature, the investments in inland shipping infrastructure would also be helpful in solving the current problems of water management. Inland waterways in Poland guaran-tee neither an adequate level of flood protection, nor the water needs fulfillment of do-mestic economy. When it comes to water reserves, Poland is one of the most deficient countries in Europe. Thus there is a need to invest in inland waterways in Poland.

  19. Generic assessment of tight-fitting annulus spacer mobility

    International Nuclear Information System (INIS)

    Robertson, J.; Micuda, L.; Van Den Brekel, N.

    2006-01-01

    This paper provides a generic assessment of the mobility of tight-fitting fuel channel annulus spacers in OPG and Bruce Power nuclear units. This assessment is applicable to all tight-fitting annulus spacers, including those used in the original fuel channel installation (Darlington Units 1-4, retubed Pickering Units 1-4, and Bruce Unit 8) and as a result of single fuel channel replacements (SFCR) (Pickering Units 5-8, Bruce Units 3-7). Tight-fitting annulus spacers were designed not to move. Pressure tube to calandria tube contact analyses, and the associated blister susceptibility assessments, have assumed that these tight-fitting spacers remain at the pre-service installed locations. Given the importance of this assumption, the technical basis for the expectation that tight-fitting annulus spacers do not move significantly from their pre-service locations, relative to the pressure tube, was reviewed in detail. The review also assessed the inspection data, comparing spacer locations from in-service and pre-service inspections. The review has concluded that tight-fitting spacers do not move sufficiently to necessitate a postulated spacer movement in fuel channel contact analyses. The paper describes the background of this issue, briefly reviews the experimental programs used to qualify the positional stability of the tight-fitting spacer design, and evaluates the current database of in-service spacer location inspection information to demonstrate that no significant movement relative to the pressure tube has been observed.

  1. Approaches to Sustainable Development in Poland

    International Nuclear Information System (INIS)

    Kostrzewa, Karina; ); Piasecki, Ryszard

    2009-01-01

    The sustainable development principle was introduced into the legal system of Poland when the Constitution of the Polish Republic was adopted in 1997. Paradoxically, in Poland - one of the few countries in the world which have introduced the concept of sustainable development at the level of the Constitution, it is difficult to find a reference to it in the political debate. The national sustainable development strategy Poland 2025 has met no response among society and today it seems to be hardly remembered by anybody. An average citizen does not know the concept of sustainable development, or has a vague notion of it, often identifying it exclusively with environmental protection. Solving social problems (the labour market, education, health protection, equality of the sexes, etc.) is not associated with sustainable development whatsoever, and neither is engagement into achieving these development targets on the global scale

  2. Economic costs of electricity production in Poland

    Beeldman, M.; Solinski, J.

    1994-02-01

    This study presents a methodology for the calculation of the economic costs of the production of electricity. This methodology is applied to assess electricity production cost in Poland by type of power station for the years 1995 and 2000. In addition, an overview is presented of the methods used by the OECD countries, particularly in the Netherlands. The main conclusions of the study are: 1) the real economic costs to generate electricity in Poland are about two times higher compared with the traditional book-keeping data; 2) the investment costs will become the most important cost component in the near future; and 3) there are considerables differences in production cost per kWh for the different types of power plants in Poland. 4 appendices, 14 refs

    Rorat, Marta; Jurek, Tomasz

    2016-01-01

    Health, safety and medical errors are currently the subject of worldwide discussion. The authors analysed medico-legal opinions trying to determine types of medical errors and their impact on the course of sepsis. The authors carried out a retrospective analysis of 66 medico-legal opinions issued by the Wroclaw Department of Forensic Medicine between 2004 and 2013 (at the request of the prosecutor or court) in cases examined for medical errors. Medical errors were confirmed in 55 of the 66 medico-legal opinions. The age of victims varied from 2 weeks to 68 years; 49 patients died. The analysis revealed medical errors committed by 113 health-care workers: 98 physicians, 8 nurses and 8 emergency medical dispatchers. In 33 cases, an error was made before hospitalisation. Hospital errors occurred in 35 victims. Diagnostic errors were discovered in 50 patients, including 46 cases of sepsis being incorrectly recognised and insufficient diagnoses in 37 cases. Therapeutic errors occurred in 37 victims, organisational errors in 9 and technical errors in 2. In addition to sepsis, 8 patients also had a severe concomitant disease and 8 had a chronic disease. In 45 cases, the authors observed glaring errors, which could incur criminal liability. There is an urgent need to introduce a system for reporting and analysing medical errors in Poland. The development and popularisation of standards for identifying and treating sepsis across basic medical professions is essential to improve patient safety and survival rates. Procedures should be introduced to prevent health-care workers from administering incorrect treatment in cases. © The Author(s) 2015.

    2015-01-01

    The aim of the study is to assess the epidemiological situation of hepatitis A in Poland in 2013 compared to previous years. The evaluation was carried out on the basis of the results of the analysis of data from the annual bulletin "Infectious diseases and poisonings in Poland in 2013" and "Vaccinations in Poland in 2013", the information from individual diseases forms and epidemiological investigations forms for hepatitis A outbreaks, sent by sanitary-epidemiological stations to the Department of Epidemiology of NIZP-PZH. In 2013, 48 cases of hepatitis A were registered in Poland. The incidence per 100,000 inhabitants was 0.12, and in particular provinces it ranged from 0.05 in the Kujawsko-Pomorskie province to 0.26 in the Wielkopolska province. The incidence of hepatitis A for men and women was at a similar level and amounted to 0.13 and 0.12/100,000. In 2013 imported cases accounted for 45.8% of the total number of hepatitis A cases. There were three outbreaks, where the total of 13 people fell ill. 2013 saw a slight decrease in the number of cases compared to the previous year. Besides, there were no significant changes in the hepatitis A epidemiological situation. In Poland, there is still very low endemicity. Since several years, there has been a decline in the number of people vaccinated against hepatitis A. All of this affects the accumulation of a fairly large population of people susceptible to the infection, which may increase incidence. Although the current hepatitis A epidemiological situation in Poland is good, it still requires monitoring, analysis and constant observation within the structured epidemiological surveillance.

    2016-08-01

    The misuse of over-the-counter (OTC) drugs became a global public health concern. Although abuse with dextrometorphan (DXM), pseudoefedrine (PSD), codeine (COD) or benzydamine (BND) may lead even to psychosis, drugs containing these substances are relatively cheap and freely available. In Poland the Act on Counteracting Drug Addiction was amended in 2015, however it seems that there are still some points which could be improved. Study was conducted between October 2014 and June 2015 using a specially designed questionnaire delivered to pharmacists from the Greater Poland region. Questionnaire consisting of 11 closed questions was distributed by direct contact and via the Internet. From over 2500 distributed questionnaires, we received 761 sheets and 680 were included. The misuse of OTC drugs is increasing in Poland from pharmacists point of view. The most popular substance was PSD followed by COD and DXM. The main reason of misuse of these drugs could be related to the use of Internet and free access to these medications. In respondents (58.2%) opinion OTC drugs containing analyzed substances should be moved into the prescription status. The misuse of OTC drugs should be considered as a very dangerous phenomenon. Although the Act on Counteracting Drug Addiction was amended in Poland in 2015, there are some facets requiring improvement. Social education may play a key role in the limitation of misuse of OTC drugs. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

  16. Post-accession economic development of Poland

    Directory of Open Access Journals (Sweden)

    Witold ORŁOWSKI

    2011-12-01

    Full Text Available The aim of this paper is to analyse the economic performance of Poland in the post-accession period. Poland joined the EU in 2004, after a long and difficult economic transition. The whole post-accession period could be divided into two sub-periods: the pre-crisis period of 2004-07, and the turbulent period of 2008-11. During the pre-crisis period, Poland recorded a fast growth, with a built-up of macroeconomic disequilibria. During the turbulent period, the economy was dealing successfully with the global financial crisis. The growth slowed down and the disequilibria were reduced. The paper discusses the growth patterns in the both sub-periods and tries to explain the factors that contributed to the good economic performance during the financial crisis. The astonishingly good economic growth results cannot be attributed to a single factor, but to a combination of many factors contributing at the same time. However, Poland has many valuable assets that may help in dealing with the further economic turbulences.

    The main objective of the THERMIE Associated Measure WE05 is to study market conditions and estimate the market for wind power in Eastern Europe. This report describes the results of a study of the conditions in Poland, which has been concentrated on the following areas: wind energy potential in Poland; data concerning the present structure of the power production system including costs; payback prices, subsidies, etc. with relation to renewable energy sources, especially wind power; information on existing wine turbines and their production in Poland; possibilities for co-production of wind turbines by Polish and EC factories, and rules and legislation pertaining to the establishment of wind turbines and to power production by wind, eg regulations related to grid connection, safety and environment. According to existing data there are possibilities for using the wind potential in certain parts of poland. The wind data have to be improved if particular sites are considered for wind parks. The current official plans concerning the energy system have taken renewable sources into consideration, including wind power that is estimated to contribute ∼ 1 GWh by 2005-2010. Wind turbines may be connected to the public grid with due regard to the strength of the line. Presently, the owner has to pay all the costs, however, new rules are under consideration. The conditions for the connection and operation of wind turbines have to be discussed with the particular utility on an an-hoc basis. (EG)

  6. Hepatitis C in Poland in 2012.

    Science.gov (United States)

    Parda, Natalia; Henszel, Lukasz; Stępień, Małgorzata

    2014-01-01

    In Poland, an estimated 2 000 HCV infections are reported annually, of which chronic stage of infections predominates (>95%). It is estimated that seroprevalence of anti-HCV and prevalence of active infections in the general population amount to ca 0.95% (more than 320 000 persons) and 0.6% (230 000 persons), respectively. The alarming finding is that approximately 90% of persons diagnosed with HCV infection are unaware of the condition and consequently hepatitis C virus may be transmitted to their contacts. The objective of the present article is to determine the epidemiology of HCV infections in Poland in 2012 comparing to the preceding years. The assessment of epidemiological situation of HCV infections in Poland was based on the analysis of aggregated data from the State Sanitary Inspection, published in "Infectious diseases and poisonings in Poland in 2012" (Czarkowski MP et al. "Infectious diseases and poisonings in Poland in 2012" Warsaw, NIPH-NIH and CSI). The data on mortality due to hepatitis C, which was obtained from the Demographic Surveys and Labour Market Department of Central Statistical Office, were also employed. In 2012, Poland reported 2 292 HCV infections, meeting 2005 definition (incidence 5.95), of which 1.4% were co-infections with HCV and HBV (33 cases). Compared to the data of 2011, the incidence was slightly lower (2 338; 6.07). Given 2009 definition, a total of 2 265 cases were reported (5.88), which constituted an increase of 3.5% compared to the data from the previous year (2 241; 5.82). Overall, 217 fatal cases due to hepatitis C were reported in 2012, of whom only 9 (4%) were due to acute stage of infection. Compared to the data from 2011, the epidemiological situation of hepatitis C in Poland has not changed significantly. The alarming fact is the increasing number of deaths due to hepatitis C. Probably, it suggests delayed diagnosis of HCV infections. Thus, it is a necessity to promote early diagnosis of HCV infections which can

    The current study concerns fundamental controls on fluid flow in tight carbonate rocks undergoing CO2 injection. Tight carbonates exposed to weak carbonic acid exhibit order of magnitude changes in permeability while maintaining a nearly constant porosity with respect to the porosity of the unreacted sample. This study aims to determine—if not porosity—what are the microstructural changes that control permeability evolution in these rocks? Given the pore-scale nature of chemical reactions, we took a digital rock physics approach. Tight carbonate mudstone was imaged using X-ray microcomputed tomography. We simulated calcite dissolution using a phenomenological numerical model that stands from experimental and microstructural observations under transport-limited reaction conditions. Fluid flow was simulated using the lattice-Boltzmann method, and the pore wall was adaptively eroded at a rate determined by the local surface area and velocity magnitude, which we use in place of solvent flux. We identified preexisting, high-conductivity fluid pathways imprinted in the initial microstructure. Though these pathways comprise a subset of the total connected porosity, they accommodated 80 to 99% of the volumetric flux through the digital sample and localized dissolution. Porosity-permeability evolution exhibited two stages: selective widening of narrow pore throats that comprised preferential pathways and development and widening of channels. We quantitatively monitored attributes of the pore geometry, namely, porosity, specific surface area, tortuosity, and average hydraulic diameter, which we qualitatively linked to permeability. This study gives a pore-scale perspective on the microstructural origins of laboratory permeability-porosity trends of tight carbonates undergoing transport-limited reaction with CO2-rich fluid.

  8. The media of sociology: tight or loose translations?

    Sociologists have increasingly come to recognize that the discipline has unduly privileged textual representations, but efforts to incorporate visual and other media are still only in their beginning. This paper develops an analysis of the ways objects of knowledge are translated into other media, in order to understand the visual practices of sociology and to point out unused possibilities. I argue that the discourse on visual sociology, by assuming that photographs are less objective than text, is based on an asymmetric media-determinism and on a misleading notion of objectivity. Instead, I suggest to analyse media with the concept of translations. I introduce several kinds of translations, most centrally the distinction between tight and loose ones. I show that many sciences, such as biology, focus on tight translations, using a variety of media and manipulating both research objects and representations. Sociology, in contrast, uses both tight and loose translations, but uses the latter only for texts. For visuals, sociology restricts itself to what I call 'the documentary': focusing on mechanical recording technologies without manipulating either the object of research or the representation. I conclude by discussing three rare examples of what is largely excluded in sociology: visual loose translations, visual tight translations based on non-mechanical recording technologies, and visual tight translations based on mechanical recording technologies that include the manipulation of both object and representation. © London School of Economics and Political Science 2015.

  9. Human zonulin, a potential modulator of intestinal tight junctions.

    Intercellular tight junctions are dynamic structures involved in vectorial transport of water and electrolytes across the intestinal epithelium. Zonula occludens toxin derived from Vibrio cholerae interacts with a specific intestinal epithelial surface receptor, with subsequent activation of a complex intracellular cascade of events that regulate tight junction permeability. We postulated that this toxin may mimic the effect of a functionally and immunologically related endogenous modulator of intestinal tight junctions. Affinity-purified anti-zonula occludens toxin antibodies and the Ussing chamber assay were used to screen for one or more mammalian zonula occludens toxin analogues in both fetal and adult human intestine. A novel protein, zonulin, was identified that induces tight junction disassembly in non-human primate intestinal epithelia mounted in Ussing chambers. Comparison of amino acids in the active zonula occludens toxin fragment and zonulin permitted the identification of the putative receptor binding domain within the N-terminal region of the two proteins. Zonulin likely plays a pivotal role in tight junction regulation during developmental, physiological, and pathological processes, including tissue morphogenesis, movement of fluid, macromolecules and leukocytes between the intestinal lumen and the interstitium, and inflammatory/autoimmune disorders.

    Maintaining a healthy gut environment is a prerequisite for sustainable animal production. The gut plays a key role in the digestion and absorption of nutrients and constitutes an initial organ exposed to external factors influencing bird's health. The intestinal epithelial barrier serves as the first line of defense between the host and the luminal environment. It consists of a continuous monolayer of intestinal epithelial cells connected by intercellular junctional complexes which shrink the space between adjacent cells. Consequently, free passing of solutes and water via the paracellular pathway is prevented. Tight junctions (TJs) are multi-protein complexes which are crucial for the integrity and function of the epithelial barrier as they not only link cells but also form channels allowing permeation between cells, resulting in epithelial surfaces of different tightness. Tight junction's molecular composition, ultrastructure, and function are regulated differently with regard to physiological and pathological stimuli. Both in vivo and in vitro studies suggest that reduced tight junction integrity greatly results in a condition commonly known as "leaky gut". A loss of barrier integrity allows the translocation of luminal antigens (microbes, toxins) via the mucosa to access the whole body which are normally excluded and subsequently destroys the gut mucosal homeostasis, coinciding with an increased susceptibility to systemic infection, chronic inflammation and malabsorption. There is considerable evidence that the intestinal barrier dysfunction is an important factor contributing to the pathogenicity of some enteric bacteria. It has been shown that some enteric pathogens can induce permeability defects in gut epithelia by altering tight junction proteins, mediated by their toxins. Resolving the strategies that microorganisms use to hijack the functions of tight junctions is important for our understanding of microbial pathogenesis, because some pathogens can

    Full Text Available Abstract Planar carbon-based electronic devices, including metal/semiconductor junctions, transistors and interconnects, can now be formed from patterned sheets of graphene. Most simulations of charge transport within graphene-based electronic devices assume an energy band structure based on a nearest-neighbour tight binding analysis. In this paper, the energy band structure and conductance of graphene nanoribbons and metal/semiconductor junctions are obtained using a third nearest-neighbour tight binding analysis in conjunction with an efficient nonequilibrium Green's function formalism. We find significant differences in both the energy band structure and conductance obtained with the two approximations.

    Butyrate, one of the SCFA, promotes the development of the intestinal barrier. However, the molecular mechanisms underlying the butyrate regulation of the intestinal barrier are unknown. To test the hypothesis that the effect of butyrate on the intestinal barrier is mediated by the regulation of the assembly of tight junctions involving the activation of the AMP-activated protein kinase (AMPK), we determined the effect of butyrate on the intestinal barrier by measuring the transepithelial electrical resistance (TER) and inulin permeability in a Caco-2 cell monolayer model. We further used a calcium switch assay to study the assembly of epithelial tight junctions and determined the effect of butyrate on the assembly of epithelial tight junctions and AMPK activity. We demonstrated that the butyrate treatment increased AMPK activity and accelerated the assembly of tight junctions as shown by the reorganization of tight junction proteins, as well as the development of TER. AMPK activity was also upregulated by butyrate during calcium switch-induced tight junction assembly. Compound C, a specific AMPK inhibitor, inhibited the butyrate-induced activation of AMPK. The facilitating effect of butyrate on the increases in TER in standard culture media, as well as after calcium switch, was abolished by compound C. We conclude that butyrate enhances the intestinal barrier by regulating the assembly of tight junctions. This dynamic process is mediated by the activation of AMPK. These results suggest an intriguing link between SCFA and the intracellular energy sensor for the development of the intestinal barrier. PMID:19625695

    2001-05-01

    The general health insurance introduced in Poland in 1999 is essentially a social insurance. In this article, the main features of the present health care system are discussed, i.e. the sources and principles of financing, ownership relations, structures, entitlements to obtain medical services and the rules of access to services. Emphasis has been put on the operations of various entities operating within the health care sector, including opportunistic conduct of the providers of services financed from public sources, cost dumping, establishing provider alliances, methods of cost control, and the fact that some patients leave the publicly financed system. In Poland, a parallel private system has been developing for many years. Systemic transformations have not changed that direction, but increased considerably the significance of household income and education as the factors that differentiate patient in equality. This article is concluded with the note on the opportunities for the development of supplementary private insurance.

    Full Text Available The article presents an outline of the issue concerning formulation of a marketing strategy and the possibility of using the knowledge on consumers' preferences for organic development of farms and their products on the example of southern Poland. The paper analyses the distribution process of organic food in the aspect of developing innovative marketing strategies. The studies were performed in 50 organic farms and on the example of 100 respondents from the region of southern Poland. In the opinion of the surveyed representatives of the organic food producers, a competitive advantage of their offer depends the most on the health values, brand, reputation, and taste. Moreover, information on products and the form and place of their sale are significant. The analysis shows that the knowledge is the most eagerly obtained from the Internet. Thus, producers should publish their profiles and pages on social media and business portals.

    Assessment of the epidemiological situation of scarlet fever in Poland in 2014. The evaluation was performed by reviewing surveillance data published in the bulletin “Infectious diseases and poisonings in Poland in 2014” as well as in previous bulletins, and unpublished data collected under Statistical survey program of official statistics. These data relate to cases of scarlet fever registered by health sanitary inspection on the basis of statutory notification of scarlet fever reported by physicians. In 2014, annual, incidence rate of scarlet fever in Poland was about 9% lower in comparison to previous year. There were 22 855 cases all over the country and the incidence was 59.5 per 100,000 population; depending on the voivodeship ranged from 19.5 in podkarpackie to 93.2 in pomorskie. The highest incidence was noted among 4-year-old children (981.4) and 5-year-old children (971.0). However the incidence among children and young people up to 15 years accounted for 95.7% of all cases. The incidence among men (67.2) was higher by 28.5% than incidence among women (52.3). Incidence rate in urban areas, in any size town, was higher than in rural areas. Overall incidence in urban areas was 66.4; in rural areas - 49.0. 1,11% of patients were hospitalized. There were no reported deaths related to scarlet fever. In the surveillance of scarlet fever it is necessary to ensure that the collected data will be valid and reliable. Very low specificity of this surveillance may not only impinge on the assessment of epidemiological situation of this disease in Poland but also overshadow the situation of other diseases, including diseases under elimination program (rubella, measles). This is one of the greatest challenges facing sanitary inspection in the coming years.

    Lyme disease is the most common tick-borne disease in Poland. Borrelia burgdorferi spirochete can occur in the whole country, which, according to ECDC, should be considered as an endemic area. Borrelia strains are transmitted to humans and certain other animals by Ixodes (1). Human infection is caused by saliva or tick vomit. Reservoir spirochete are numerous species of animals, mainly rodents. Lyme disease, due to its multifocal character, rich symptomatology and diagnostic problems, is a serious challenge for clinicians and epidemiologists The aim of this study was to assess the epidemiological situation of Lyme disease in Poland in 2015 in comparison to the previous years The descriptive analysis was based on data retrieved from routine mandatory surveillance system and published in the annual bulletin “Infectious diseases and poisonings in Poland in 2015” (2) Despite observed in recent years the tendency to growth of number of cases, in 2015 was marked by growth inhibition incidence of Lyme disease.In 2015, 13 625 cases were registered in Poland, ie by 0.7% less than in the previous year. The overall incidence in the country was 35.4 per 100 000 population - the highest was recorded in the Podlaskie voivodeship - 96.3 per 100 000 inhabitants. In 2015, 1905 (14%) people were hospitalized due to Lyme disease In 2015, for the first time in a few years, the growth rate of Lyme disease has been stopped. Registered 0.7% less cases than in the previous year. There is still a need for bringing awareness of the need for diagnostic laboratory testing according to recommendations, which will improve the accuracy of the diagnosis

  5. Church unions and their consequences in Poland

    2014-11-01

    Full Text Available Orthodox Christians in Poland have faced numerous attempts to be forced into union with the Roman Catholic Church, ranging from the thirteenth to the twentieth century. The first attempt at a union between the Roman Catholic Church and the Orthodox Church took place as early as the mid-thirteenth century. Another attempt at forcing the Orthodox Church into union with Rome took place during the reign of Ladislaŭ II Yagiello. The problem of church union returned in the reign of Alexander the Yagiellonian. When Ivan III rejected all projects for bringing the Florence such a union into practice, discussion on church union disappeared until the end of the sixteenth century. The mission of the papal legate, Father Antonio Possevino, to Ivan IV, had been intended to draw Moscow into the union, and its failure caused the papacy to concentrate its efforts on the Orthodox Church in Poland. The Ruthenian bishops’ obedience to the Pope was officially announced on the 8 October 1596. The decisions of the Uniate-Catholic synod were met with numerous protests from the Orthodox clergy and nobility. The larger part of the clergy and the faithful, together with bishops remained in the Orthodox camp. Despite the failure of the Brest Synod in fully uniting Orthodox and Roman churches, new union projects concerning the Orthodox Church in Poland continued to arise prior to the end of 18th century. The Vatican’s interest in the Orthodox Church in Central Europe was renewed at the end of the First World War. On April 1st, 1917, the Pope created the Congregation for the Oriental Churches which was responsibile for all issues relating to the activities of all the Eastern denominations. Despite aims at unification, attempts at church union have had a negative influence on the relations between the Roman Catholic and Polish Orthodox Church in contemporary Poland. The result of centuries of attempts at unification under the Pope has been fragmentation and division.

    In 1997, a new Energy Law was passed in Poland. An important element of the law is that local energy planning is made obligatory. The law describes obligatory tasks and procedures for Polish municipalities related to planning and organisation of the energy sector. With the objective of supporting the Polish municipalities in their obligations according to the energy law of 1997, the project 'Energy Planning in Poland at Municipal Level - Support to Decision Makers' was launched. As part of the project, Municipal Guideline Reports have been elaborated for three model municipalities. These guidelines present the basis for the Energy Supply Plans in these municipalities. For the city of Legionowo, the following was recommended: 1. The planning processes initiated during the project should be continues/followed up, 2. Master Plan for the district heating system should be prepared, 3. The possibilities of establishment of a major natural gas-fired CHP plant of the Combined Cycle type should be investigated. The present report is the final Master Plan based on the following reports: Master Plan for Legionowo - Status Report; Master Plan for Legionowo - Hydraulic Analysis; CHP Plant Legionowo Poland - CHP Feasibility Analysis.

    2016-07-01

    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. Copyright © 2016 Associazione Italiana di Fisica Medica. Published by Elsevier Ltd.

  14. Hemolymph metabolites and osmolality are tightly linked to cold tolerance of Drosophila species: a comparative study.

    Drosophila, like most insects, are susceptible to low temperatures, and will succumb to temperatures above the freezing point of their hemolymph. For these insects, cold exposure causes a loss of extracellular ion and water homeostasis, leading to chill injury and eventually death. Chill-tolerant species are characterized by lower hemolymph [Na(+)] than chill-susceptible species and this lowered hemolymph [Na(+)] is suggested to improve ion and water homeostasis during cold exposure. It has therefore also been hypothesized that hemolymph Na(+) is replaced by other 'cryoprotective' osmolytes in cold-tolerant species. Here, we compared the hemolymph metabolite profiles of five drosophilid species with marked differences in chill tolerance. All species were examined under 'normal' thermal conditions (i.e. 20°C) and following cold exposure (4 h at 0°C). Under benign conditions, total hemolymph osmolality was similar among all species despite chill-tolerant species having lower hemolymph [Na(+)]. Using NMR spectroscopy, we found that chill-tolerant species instead have higher levels of sugars and free amino acids in their hemolymph, including classical 'cryoprotectants' such as trehalose and proline. In addition, we found that chill-tolerant species maintain a relatively stable hemolymph osmolality and metabolite profile when exposed to cold stress while sensitive species suffer from large increases in osmolality and massive changes in their metabolic profiles during a cold stress. We suggest that the larger contribution of classical cryoprotectants in chill-tolerant Drosophila plays a non-colligative role for cold tolerance that contributes to osmotic and ion homeostasis during cold exposure and, in addition, we discuss how these comparative differences may represent an evolutionary pathway toward more extreme cold tolerance of insects. © 2016.

    The production of secretory proteins at the ER (endoplasmic reticulum) depends on a ready supply of energy and metabolites as well as the close monitoring of the chemical conditions that favor oxidative protein folding. ER oxidoreductases and chaperones fold nascent proteins into their export-competent three-dimensional structure. Interference with these protein folding enzymes leads to the accumulation of unfolded proteins within the ER lumen, causing an acute organellar stress that triggers the UPR (unfolded protein response). The UPR increases the transcription of ER chaperones commensurate with the load of newly synthesized proteins and can protect the cell from ER stress. Persistant stress, however, can force the UPR to commit cells to undergo apoptotic cell death, which requires the emptying of ER calcium stores. Conversely, a continuous ebb and flow of calcium occurs between the ER and mitochondria during resting conditions on a domain of the ER that forms close contacts with mitochondria, the MAM (mitochondria-associated membrane). On the MAM, ER folding chaperones such as calnexin and calreticulin and oxidoreductases such as ERp44, ERp57 and Ero1alpha regulate calcium flux from the ER through reversible, calcium and redox-dependent interactions with IP3Rs (inositol 1,4,5-trisphophate receptors) and with SERCAs (sarcoplasmic/endoplasmic reticulum calcium ATPases). During apoptosis progression and depending on the identity of the ER chaperone and oxidoreductase, these interactions increase or decrease, suggesting that the extent of MAM targeting of ER chaperones and oxidoreductases could shift the readout of ER-mitochondria calcium exchange from housekeeping to apoptotic. However, little is known about the cytosolic factors that mediate the on/off interactions between ER chaperones and oxidoreductases with ER calcium channels and pumps. One candidate regulator is the multi-functional molecule PACS-2 (phosphofurin acidic cluster sorting protein-2). Recent studies suggest that PACS-2 mediates localization of a mobile pool of calnexin to the MAM in addition to regulating homeostatic ER calcium signaling as well as MAM integrity. Together, these findings suggest that cytosolic, membrane and lumenal proteins combine to form a two-way switch that determines the rate of protein secretion by providing ions and metabolites and that appears to participate in the pro-apoptotic ER-mitochondria calcium transfer.

    of differentiation. Concomitant with agonist production, murine fibroblasts undergo two rounds of mitosis referred to as mitotic clonal expansion. Here we show that mouse embryonic fibroblasts deficient in either of two cell cycle inhibitors, the transcription factor p53 or its target gene encoding the cyclin......-dependent kinase inhibitor p21, exhibit increased adipogenic potential. The antiadipogenic effect of p53 relied on its transcriptional activity and p21 expression but was circumvented by administration of an exogenous PPAR agonist suggesting a linkage between cell cycling and PPAR ligand production. Indeed, cell...... cycle inhibitory compounds decreased PPAR ligand production in differentiating 3T3-L1 preadipocytes. Furthermore, these inhibitors abolished the release of arachidonic acid induced by the hormonal cocktail initiating adipogenesis. Collectively, our results suggest that murine fibroblasts require clonal...

    Full Text Available While most past studies have emphasized the relationships between specific forest stands and edaphic factors, recent observations in Central African moist forests suggested that an increase of slash-and-burn agriculture since 3000–2000 BP (Before Present could be the main driver of the persistence of light-demanding tree species. In order to examine anthropogenic factors in the persistence of such populations, our study focused on Pericopsis elata, an endangered clustered timber species. We used a multidisciplinary approach comprised of botanical, anthracological and archaeobotanical investigations to compare P. elata patches with surrounding stands of mixed forest vegetation (“out-zones”. Charcoal samples were found in both zones, but were significantly more abundant in the soils of patches. Eleven groups of taxa were identified from the charcoals, most of them also present in the current vegetation. Potsherds were detected only inside P. elata patches and at different soil depths, suggesting a long human presence from at least 2150 to 195 BP, as revealed by our charcoal radiocarbon dating. We conclude that current P. elata patches most likely result from shifting cultivation that occurred ca. two centuries ago. The implications of our findings for the dynamics and management of light-demanding tree species are discussed.

For these insects, cold exposure causes a loss of extracellular ion and water homeostasis, leading to chill injury and eventually death. Chill......-tolerant species are characterized by lower hemolymph [Na(+)] than chill-susceptible species and this lowered hemolymph [Na(+)] is suggested to improve ion and water homeostasis during cold exposure.

    Adiaspiromycosis is a rare fungal infection caused by saprophytic fungi Emmonsia spp. (type Ascomycota) occurring especially in small free-living mammals. The aim of this study was to evaluate the occurrence of histopathological lesions asscociated with adiaspiromycosis in the Eurasian beaver inhabiting Poland. In order to evaluate the presence of natural adiaspiromycosis we systematically investigated beaver populations from north-eastern Poland for adiaspores in the lungs. This study reveals for the first time the presence of pulmonary adiaspiromycosis of Eurasian beaver in Poland. As far as we know, there is no published data regarding pulmonary adiaspiromycosis in human patients in Poland.

  13. Unconventional Tight Reservoirs Characterization with Nuclear Magnetic Resonance

    2017-12-01

    The increase in tight reservoir exploitation projects causes producing many papers each year on new, modern, and modified methods and techniques on estimating characteristics of these reservoirs. The most ambiguous of all basic reservoir property estimations deals with permeability. One of the logging methods that is advertised to predict permeability but is always met by skepticism is Nuclear Magnetic Resonance (NMR). The ability of NMR to differentiate between bound and movable fluids and providing porosity increased the capability of NMR as a permeability prediction technique. This leads to a multitude of publications and the motivation of a review paper on this subject by Babadagli et al. (2002). The first part of this presentation is dedicated to an extensive review of the existing correlation models for NMR based estimates of tight reservoir permeability to update this topic. On the second part, the collected literature information is used to analyze new experimental data. The data are collected from tight reservoirs from Canada, the Middle East, and China. A case study is created to apply NMR measurement in the prediction of reservoir characterization parameters such as porosity, permeability, cut-offs, irreducible saturations etc. Moreover, permeability correlations are utilized to predict permeability. NMR experiments were conducted on water saturated cores. NMR T2 relaxation times were measured. NMR porosity, the geometric mean relaxation time (T2gm), Irreducible Bulk Volume (BVI), and Movable Bulk Volume (BVM) were calculated. The correlation coefficients were computed based on multiple regression analysis. Results are cross plots of NMR permeability versus the independently measured Klinkenberg corrected permeability. More complicated equations are discussed. Error analysis of models is presented and compared. This presentation is beneficial in understanding existing tight reservoir permeability models. The results can be used as a guide for choosing

    the development of the nuclear power programme; and PAA's proactive approach to coordination with Poland's Office of Technical Inspection. The IRRS team made several recommendations and suggestions for PAA as it grows in the next few years, facing challenges and increasing demands as its nuclear power programme expands. To position PAA to address its growth, additional responsibilities, and the retirement of many senior managers, and to maintain its strong focus on safety for currently regulated facilities and activities, the IRRS team advised PAA to: Establish and frequently review that there is a clear link between PAA's organizational goals and objectives, and resource planning, such as staffing and strategies for external support; Consider strengthening and documenting PAA's management system; and Develop and strengthen internal guidance to document authorization processes, review, assessment and inspection procedures. In its preliminary report, the IAEA team's main conclusions have been conveyed to PAA. A final report will be submitted to the Government of Poland in about three months. PAA has informed the team that the final report will be made publicly available. The IAEA encourages nations to invite a follow-up IRRS mission about two years after the mission has been completed. Background The team reviewed the legal and regulatory framework for nuclear safety and addressed all facilities regulated by PAA. This was the 46th IRRS mission conducted by the IAEA. About IRRS Missions IRRS missions are designed to strengthen and enhance the effectiveness of the national nuclear regulatory infrastructure of States, while recognizing the ultimate responsibility of each State to ensure safety in this area. This is done through consideration of regulatory, technical and policy issues, with comparisons against IAEA safety standards and, where appropriate, good practices elsewhere. (IAEA)

    2007-06-19

    The objectives of this project are to develop and test new techniques for creating extensive, conductive hydraulic fractures in unconventional tight gas reservoirs by statistically assessing the productivity achieved in hundreds of field treatments with a variety of current fracturing practices ranging from 'water fracs' to conventional gel fracture treatments; by laboratory measurements of the conductivity created with high rate proppant fracturing using an entirely new conductivity test - the 'dynamic fracture conductivity test'; and by developing design models to implement the optimal fracture treatments determined from the field assessment and the laboratory measurements. One of the tasks of this project is to create an 'advisor' or expert system for completion, production and stimulation of tight gas reservoirs. A central part of this study is an extensive survey of the productivity of hundreds of tight gas wells that have been hydraulically fractured. We have been doing an extensive literature search of the SPE eLibrary, DOE, Gas Technology Institute (GTI), Bureau of Economic Geology and IHS Energy, for publicly available technical reports about procedures of drilling, completion and production of the tight gas wells. We have downloaded numerous papers and read and summarized the information to build a database that will contain field treatment data, organized by geographic location, and hydraulic fracture treatment design data, organized by the treatment type. We have conducted experimental study on 'dynamic fracture conductivity' created when proppant slurries are pumped into hydraulic fractures in tight gas sands. Unlike conventional fracture conductivity tests in which proppant is loaded into the fracture artificially; we pump proppant/frac fluid slurries into a fracture cell, dynamically placing the proppant just as it occurs in the field. From such tests, we expect to gain new insights into some of the critical

  20. Preconditioning Filter Bank Decomposition Using Structured Normalized Tight Frames

    Directory of Open Access Journals (Sweden)

    Martin Ehler

    2015-01-01

    Full Text Available We turn a given filter bank into a filtering scheme that provides perfect reconstruction, synthesis is the adjoint of the analysis part (so-called unitary filter banks, all filters have equal norm, and the essential features of the original filter bank are preserved. Unitary filter banks providing perfect reconstruction are induced by tight generalized frames, which enable signal decomposition using a set of linear operators. If, in addition, frame elements have equal norm, then the signal energy is spread through the various filter bank channels in some uniform fashion, which is often more suitable for further signal processing. We start with a given generalized frame whose elements allow for fast matrix vector multiplication, as, for instance, convolution operators, and compute a normalized tight frame, for which signal analysis and synthesis still preserve those fast algorithmic schemes.

  1. Maximally Localized Radial Profiles for Tight Steerable Wavelet Frames.

    Science.gov (United States)

    Pad, Pedram; Uhlmann, Virginie; Unser, Michael

    2016-05-01

    A crucial component of steerable wavelets is the radial profile of the generating function in the frequency domain. In this paper, we present an infinite-dimensional optimization scheme that helps us find the optimal profile for a given criterion over the space of tight frames. We consider two classes of criteria that measure the localization of the wavelet. The first class specifies the spatial localization of the wavelet profile, and the second that of the resulting wavelet coefficients. From these metrics and the proposed algorithm, we construct tight wavelet frames that are optimally localized and provide their analytical expression. In particular, one of the considered criterion helps us finding back the popular Simoncelli wavelet profile. Finally, the investigation of local orientation estimation, image reconstruction from detected contours in the wavelet domain, and denoising indicate that optimizing wavelet localization improves the performance of steerable wavelets, since our new wavelets outperform the traditional ones.

    Full Text Available The circumstances of implicating Serbia (in 1914 and Poland (in 1939 into world wars by the forces provoking these conflicts, as well as the history of the heroic resistance of both mentioned organisms against the aggressors having numerous advantages, deserve to be constantly reminded as great lessons for the next generations of Europeans. The anniversaries of the break out of both world wars constitute a great opportunity for this type of reminder. In the presented text, compiling the Serbian experiences of the war started in 1914 with the Polish experience of the war which broke out a quarter of century later, the author stresses the follow­ing issues: - the reaction of Serbia/Poland on declaring the wars 1914/1939 (in detail, and also (in general: - the situation of war seclusion of Serbia/Poland in 1914/1939 experienced despite having the allies, - huge discrepancies of the aggressors' and the defenders' forces, as well as the resistance, exceeding the estimated opportunities, of the attacked countries towards the enemies, - the scale of the Serbian martyrdom in the 1st and Polish in the 2nd world wars, - the appearance of the war success, redeemed with extremely great sacrifice, and the presence of the threat for the Serbian/ Polish nation in the order shaped as a result 1st/2nd world war. The fragments of sources quoted in the article as well as the authors' considerations, are exhibited as key terms and simultane­ously as the common features of the Serbs and the Poles, enhanced at the moments of threat for both the nations and their countries: faith (in victory, in the help of Providence, honour, the spirit of fight and being ready for uncompromising resistance to aggressors. These val­ues constitute an essential element of comparison in the search of understanding the Serbian and Polish history and attitudes as well as the choices made by the Serbs and the Poles.

  9. [Medical student curriculum in psychiatry in Poland].

    Bilikiewicz, A

    1999-01-01

    The author describes present medical student curricula in psychiatry in Polish medical schools based on the questionnaire sent to all the lecturers of the subject in Poland. The questionnaire contained questions concerning the schedule of lectures, seminars and classes (the list of topics) as well as the number of hours of the forms of activities like interpersonal training, discussion groups, internship, etc. We also asked on which year of studies the course in psychiatry took place. The questionnaire included our request to describe the level of integration of psychiatry and other pre-clinical and clinical subjects as well as to enclose a recommended reading list (handbooks and other items of literature). The last question dealt with the problem of assessment of lectures and classes by students. The results of the questionnaire reveal great differences in the curricula of psychiatry in various schools in Poland. The differences lie both in the courses and the number of hours devoted to teaching psychiatry (in most schools it was 120 hours or less). In 7 schools students learn psychiatry in the 6th i.e. the last year of their studies. In 2 schools lectures in psychiatry are given in the th year. In Kraków and Gdańsk the courses in psychiatry consist of 150 and 160 hours respectively. The author proposes unification of the curricula in psychiatry concerning both the number of hours of classes and lectures, and topics as well as introducing the diagnostic and classifying criteria ICD-10 (WHO) since Poland is going to join EU.

    Full Text Available Introduction : The first survey of bariatric surgery in Poland was published in 2007. New trends are observed worldwide, and there is a current need to investigate the status of bariatric surgery in Polish institutions. This survey was initiated to gain an overview of Polish bariatric surgery during 2007–2014. Aim : To analyze the number and types of bariatric procedures performed in Polish institutions in 2014 and to perform a trend analysis from 2007 to 2014. Material and methods : A questionnaire regarding the numbers and types of bariatric procedures performed between 2007 and 2014 was e-mailed to all members of the Bariatric Society (a branch of the Association of Polish Surgeons and to 28 surgical departments. Trend analyses from 2007 to 2014 were performed. Results: Among the surgical departments, 16 (57% responded. The results showed that 1499 bariatric procedures were performed in Poland in 2014, with 96.4% done laparoscopically. The highest number was from Masovian Voivodeship. The most commonly reported procedures were laparoscopic sleeve gastrectomy (LSG (60.7%, followed by laparoscopic Roux-en-Y gastric bypass (19.2%, mini gastric bypass (11.1%, and adjustable gastric banding (7.6%. Most significant was the rise in prevalence of LSG from 8.0% to 60.4% of the total bariatric procedures from 2007 to 2014. Conclusions : Laparoscopic sleeve gastrectomy is currently the most frequently performed bariatric procedure in Poland. The accuracy of the national survey of procedures would be enhanced if we could create a national registry.

    Research highlights: → We disrupted epidermal tight junction barrier in reconstructed epidermis. → It altered Ca 2+ distribution and consequentially differentiation state as well. → Tight junction should affect epidermal homeostasis by maintaining Ca 2+ gradient. -- Abstract: It is well known that calcium ions (Ca 2+ ) induce keratinocyte differentiation. Ca 2+ distributes to form a vertical gradient that peaks at the stratum granulosum. It is thought that the stratum corneum (SC) forms the Ca 2+ gradient since it is considered the only permeability barrier in the skin. However, the epidermal tight junction (TJ) in the granulosum has recently been suggested to restrict molecular movement to assist the SC as a secondary barrier. The objective of this study was to clarify the contribution of the TJ to Ca 2+ gradient and epidermal differentiation in reconstructed human epidermis. When the epidermal TJ barrier was disrupted by sodium caprate treatment, Ca 2+ flux increased and the gradient changed in ion-capture cytochemistry images. Alterations of ultrastructures and proliferation/differentiation markers revealed that both hyperproliferation and precocious differentiation occurred regionally in the epidermis. These results suggest that the TJ plays a crucial role in maintaining epidermal homeostasis by controlling the Ca 2+ gradient.

    1985-01-01

    A radiation-tight coupling arrangement for coupling a machining laser to a hot cell containing radioactive material, comprising a cell flange integrally formed on the confinement wall which defines a cell opening, a cell door formed to interlock tightly with the cell flange, thereby closing the cell opening, an elongated container movably arranged in the sleeve and having a container flange defining a container opening and connected by a sealing bellows, a container door formed to interlock tightly with the container flange and to interlock with the cell door when the container flange interlocks with the cell flange, and a machining line translationally arranged in the container. When the container is in a retracted position, a radiation blocking drum intervenes between the cell opening and the container opening. The radiation blocking drum is rotated to allow the container to translate toward the cell. As a result of rotation of the container, the container flange interlocks with the cell flange and the container door interlocks with the cell door. The container door and cell door are then removed in tandem, allowing the machine head of the machining line to be inserted into the hot cell. The laser beam passes through the machine head and impinges on the radioactive material to be cut

    Carbon is very unique in among the elements and its ability to form strong chemical bonds with a variety number such as two carbons (graphene) and four carbons (diamond). This combination of strong bonds with tight mass and high melting point makes them technologically and scientifically important in nanoscience development. Tight-binding model (TB) is one of the semi-empirical approximations used in quantum mechanical world which is restricted to the Linear Combinations of Localized Atomic Orbitals (LCAO). Currently, there are many approaches in tight-binding calculation. In this paper, we have reproduced a polynomial scaling function by fitting to the TB model. The model is then applied into carbon molecules and obtained the energy bands of the system. The elements of the overlap Hamiltonian matrix in the model will be depending on the parameter of the polynomials. Our purpose is to find out a set of parameters in the polynomial which were commonly fit to an independently calculated band structure. We used minimization approach to calculate the polynomial coefficients which involves differentiation of eigenvalues in the eigensystem. The algorithm of fitting the parameters is carried out in FORTRAN.

  15. Physicians and abortion: provision, political participation and conflicts on the ground--the cases of Brazil and Poland.

    2011-01-01

    Two qualitative studies have been conducted between 2002 and 2009 in Poland and Brazil, two different geopolitical settings in which the Catholic Church has had a significant political influence and where abortion is highly restricted. In both countries, struggles for abortion rights have played an important role in challenging the current restrictive policies and bringing attention to the plight of women unable to obtain abortions. This article examines the political role that physicians play in these contestations, drawing on some findings of two larger qualitative studies. In Poland semi-structured interviews were conducted with 26 physicians in Warsaw and Krakow and with 55 women aged 18 to 45 in Gdańsk. In Brazil questionnaires were administered and semi-structured interviews conducted with 22 obstetrician-gynecologists and 23 health professionals in two public maternity hospitals in Salvador da Bahia. This article argues that gynecologists' perspectives and practices not only reflect or heed religious precepts on reproductive rights, but are also deeply influenced by inadequate medical training and by the fear of being prosecuted or stigmatized, especially in Brazil. The political non-engagement of physicians in Poland is driven by the lack of abortion rights discourse in the public arena, poor links with women's rights groups, and the lack of political unity within the medical community. Comparisons between Brazil and Poland ultimately suggest that strong liaisons between physicians and the feminist movement influence physicians' attitudes and political engagement and are most promising in abortion rights advocacy efforts.

    Evaluation of the epidemiological situation of campylobacteriosis in Poland in 2013 and 2014 in comparison with the situation in the previous years. The evaluation of the epidemiological situation was carried out on the basis of the analysis of the data contained in the annual bulletins “Infectious diseases and poisonings in Poland” for the years 2012- 2014, extended by the information from the individual questionnaires of diseases and forms of the epidemiological investigations of outbreaks of campylobacteriosis, sent by the sanitary-epidemiological stations to the Department of Epidemiology and also on data from the Department of Demographic Studies of the Central Statistical Office. In 2013 in Poland it was registered 552 cases of campylobacteriosis, while in 2014 the number of registered cases was 652. It is respectively by almost 30% and 50% more than in 2012. The overall incidence for 2013 was 1.43 and for 2014 it was 1.69 per 100 000. In 2013 all reported cases were classified as confirmed, whereas in 2014 – number of confirmed cases was 650, and two as probable. Both in 2013 and in 2014 incidence much higher than the total for the in three provinces: Śląskie (respectively 3.89 and 4.7/ 100 000), Warmińsko- Mazurskie (4.42 and 3.53/ 100 000) and Lubuskie (3.03 and 4.51/100000) incidence was both in 2013 and 2014 Markedly higher then for the country as a whole. The percentage of hospitalization was higher than in previous years and amounted in 2013 to 71.4% and in 2014 to 74.4%. In 2013 Campylobacter species was identified in more than 83% of patients and in almost 87% in 2014. In 2013 over 77% and in 2014 as much as 82% of cases were caused by C. jejuni, and correspondingly more than 6% and almos 5% by C.coli. As in previous years, the majority of cases, in 2013 - 435 (79%) and in 2014 - 491 (75%) occurred in the age group 0-4. In 2013 therte were recorded two, and 2014 - 7 outbreaks caused by Campylobacter jejuni. In Poland, despite the gradual

    In the 21 st century energy cooperation is one of the key factors of fundamental importance for the maintenance of sustainable development. Broadly perceived energy issues offer extensive opportunities for international cooperation and economic integration through the implementation of major infrastructural projects. Energy cooperation should also take into account such key factors as energy efficiency and environment protection. In all these areas cooperation will be based both on instruments available in the framework of regional collaboration in the framework of the European Policy. The result of that policy should be to set up a new nuclear power station in Poland and prepare experts in this area. (author)

    The seminar held in Warsaw by the CIFOPE from 23 to 25 november 1992 was centered around the restructuring of the coal industry and its implications for the Polish economy in the context of the current deep-running economic reforms. Partly based on French experience, this seminar shed some light on long-term problems for Poland like the kind of industrial policy that will be needed to avoid desertification problems, the need for price reform in the pursuit of profitability, and the networks and financial aids needed to restructure on such a large scale, considering that coal is a key sector in the Polish economy

    Full Text Available Chara strigosa is reported from several lakes in Poland. The finds were published by Izabella Dąmbska in 1966, but have not been recognised internationally, presumably because Dąmbska's article was published in a local paper in Polish. We give a short description of Charetum strigosa first described by Dąmbska. One of the lakes with C. strigosa is reported with luxuriant growth of a blue-green bacteria common in water blooms. There is a need to survey these lakes in order to prevent an increasing eutrophication.

    Environmental deterioration in Poland particularly in 1970's, was a result of an incorrect investment policy and indifferent attitude to the principles of the preservation of nature. Water resources, as part of the environment were affected accordingly. Shortage in water resources is caused by deterioration activity of the industrial, the progressing urban development, overconsumption caused by low prices of water and low status the legislation connected with the natural environment. The European integration processes going on make it necessary to adapt the Polish standards and technological solutions in the sphere of the environmental protection to the standards required by the European Union. The destroyed natural environment cannot secure living at a relatively high standard. Hence the concept of ecological safety based on the conviction that there is no high quality J. life without a high quality of the surrounding environment' has more followers. The main purpose of this paper is to describe the nature and scope of water pollution in Poland with an emphasis on current threats to water quality, with achievements in last decade and background of other European countries.

    International non-proliferation efforts have been taken to reduce the risk related to nuclear materials and radioactive sources. The physical security of nuclear facilities to prevent acts of sabotage or terrorism and to protect nuclear materials against loss or seizure is an essential element of the nuclear non-proliferation regime. Iraq case and the end of the Cold War have influenced the development of co-operation and openness in many countries. Poland due to: - its geolocation, - a growing number of post Chernobyl contamination transports and - high risk to become a transit country in illicit trafficking of nuclear materials and radioactive sources, initiated deployment of the fixed installation instruments at the border check-points. Since the end of 1990 to now 103 such devices have been installed. Broader involvement in combating illicit nuclear trafficking of Border Guards, Customs Services, Police and Intelligence Security has been noticed. Paper presents Poland's experience in implementing national prevention measures to reduce nuclear proliferation risk and in detecting capabilities against illicit nuclear traffic. (author)

    The aim of the study is to assess epidemiological situation of infectious and parasitic diseases in Poland in 2014, and an indication of the potential health risks from communicable diseases occurring in other areas of the globe. This paper is a summary of the analysis and evaluation of the results of epidemiological surveillance of infectious diseases in Poland in 2014, and those elements of European and global epidemiological background, which in this period had an impact on the epidemiological situation in Poland or constituted a threat. The main source of data for this study are statistical reports included in annual bulletins “Infectious diseases and poisoning in Poland in 2014” and “Immunizations in Poland in 2014” (NIPH-PZH, GIS, Warsaw 2015) and the data contained in the articles of „Epidemiological chronicle” presented in the Data on deaths are based on the statement of the Department for Demographic Research and Labour Market CSO presenting numbers of deaths from infectious and parasitic diseases registered in Poland in 2014, and in the previous years. Upper respiratory tract infection classified as “suspected flu and the flu season” in the since many years are the largest position among the diseases subject to disease surveillance. In the last decade, particularly large increase in the incidence of upper respiratory tract infection was reported in the flu season 2013., when the increase in comparison to the median of years 2008-2012 amounted to 189.8%. In 2014. Number of reported cases was 3 137 056 which represented a nonsignificant decrease of 0.8% compared with the previous year. However, compared to the median of the years 2008-2012 it was an increase of 187.4%. Better then based on calendar year is a picture obtained by examining the incidence of seasonal periods in the annual, but counted from 1 September to 31 August of the following year. In such a setup, in the 2012/2013 season were recorded 3 025 258 of cases, and in the season

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

    2017-10-01

    Analytical expressions for the fields of a radially polarized, ultrashort, and tightly focused laser pulse propagating in a linear-response plasma are derived and discussed. The fields are obtained from solving the inhomogeneous wave equations for the vector and scalar potentials, linked by the Lorenz gauge, in a plasma background. First, the scalar potential is eliminated using the gauge condition, then the vector potential is synthesized from Fourier components of an initial uniform distribution of wavenumbers, and the inverse Fourier transformation is carried out term-by-term in a truncated series (finite sum). The zeroth-order term in, for example, the axial electric field component is shown to model a pulse much better than its widely used paraxial approximation counterpart. Some of the propagation characteristics of the fields are discussed and all fields are shown to have manifested the expected limits for propagation in a vacuum.

    Full Text Available Abstract
    The Standard Method was used for three field censuses of the otter Lutra lutra distribution in Poland. In the first national survey in 1991-1994 evidence of otters was found throughout the country, with 80% of positive sites on 2000 sites visited. Only two areas, Silesia in the south and Central Poland, had very few signs of otters. The following censuses in Central and Eastern Poland (1996-1998 and 2003 showed the otter expanded its range and recolonised much area of Central Poland, including about 700 km of rivers in the catchment of River Bzura. The number of positive 10x10 km UTM squares increased twice as compared to first survey (1991-1994. The rate of expansion was very high in comparison to other studies in European countries. This could be due to the functional cohesion of network of rivers and lakelands in Poland. The expansion of otters was accompanied by change in habitat selection: preference for optimal habitats (unregulated rivers with tree and other vegetation cover decreased while suboptimal and marginal habitats (e.g. channels, regulated rivers in towns were occupied more frequently as compared to first survey. The negative side-effect of the expansion of the species is the increase of damages on fishponds, with consequent increase of pressure by fishpond owners to permit shooting of otters and/or to promote damage compensation.

    Full Text Available A very significant form of company activity determining its development and even survival is innovation activity. Raising capital for the implementation of innovation is an important but not the only factor in the introduction of innovation. Characteristics of innovation, and in particular the risk of failure, make for a significant difficulty in obtaining external financing, particularly from third parties, which is an obstacle to their development and implementation. The subject of discussion in the article is the hybrid formula mezzanine type of financing innovative projects implemented both in start-up companies and in already well established companies. The purpose of the article is to discuss the possibilities and to perform an analysis of the practices followed by mezzanine funds in Poland in respect to the innovation activities of Polish companies. Research presented in the article was conducted on the basis of information on investments performed by mezzanine funds in Poland. Of particular importance for the innovativeness of the economy is to have companies from the SME sector, and therefore we also carried out research in this group. Innovations are often initiated in special purpose companies, start-up, etc., that operate in the SME sector. Therefore, the financing of innovation cannot be ignored as a thread of innovation in SMEs. The study involved interviews in several companies in the sector. The study concerned the possibilities of financing innovation involving mezzanine, knowledge of hybrid forms of financing, preparedness for hybrid financing. Studies are not representative, but are rather sounding a view to clarify any further research. Hypothesis: mezzanine financing, utilizing its specific benefits, is increasingly used to finance the gap in the financing of innovation, in particular special purpose companies in the SME sector. So the hypothesis raises two strands of research. The first concerned the financing of innovation

    Full Text Available A review on the recent advances of the flow and transport phenomena in tight and shale formations is presented in this work. Exploration of oil and gas in resources that were once considered inaccessible opened the door to highlight interesting phenomena that require attention and understanding. The length scales associated with transport phenomena in tight and shale formations are rich. From nanoscale phenomena to field-scale applications, a unified frame that is able to encounter the varieties of phenomena associated with each scale may not be possible. Each scale has its own tools and limitations that may not, probably, be suitable at other scales. Multiscale algorithms that effectively couple simulations among various scales of porous media are therefore important. In this article, a review of the different length scales and the tools associated with each scale is introduced. Highlights on the different phenomena pertinent to each scale are summarized. Furthermore, the governing equations describing flow and transport phenomena at different scales are investigated. In addition, methods to solve these equations using numerical techniques are introduced. Cross-scale analysis and derivation of linear and nonlinear Darcy’s scale laws from pore-scale governing equations are described. Phenomena occurring at molecular scales and their thermodynamics are discussed. Flow slippage at the nanosize pores and its upscaling to Darcy’s scale are highlighted. Pore network models are discussed as a viable tool to estimate macroscopic parameters that are otherwise difficult to measure. Then, the environmental aspects associated with the different technologies used in stimulating the gas stored in tight and shale formations are briefly discussed.

    Highlights: ► Cardiac tight junctions are present between coronary endothelial cells. ► Ischemic preconditioning preserves the structural and functional integrity of tight junctions. ► Myocardial edema is prevented in hearts subjected to ischemic preconditioning. ► Ischemic preconditioning enhances translocation of ZO-2 from cytosol to cytoskeleton. -- Abstract: Ischemic preconditioning (IPC) is one of the most effective procedures known to protect hearts against ischemia/reperfusion (IR) injury. Tight junction (TJ) barriers occur between coronary endothelial cells. TJs provide barrier function to maintain the homeostasis of the inner environment of tissues. However, the effect of IPC on the structure and function of cardiac TJs remains unknown. We tested the hypothesis that myocardial IR injury ruptures the structure of TJs and impairs endothelial permeability whereas IPC preserves the structural and functional integrity of TJs in the blood–heart barrier. Langendorff hearts from C57BL/6J mice were prepared and perfused with Krebs–Henseleit buffer. Cardiac function, creatine kinase release, and myocardial edema were measured. Cardiac TJ function was evaluated by measuring Evans blue-conjugated albumin (EBA) content in the extravascular compartment of hearts. Expression and translocation of zonula occludens (ZO)-2 in IR and IPC hearts were detected with Western blot. A subset of hearts was processed for the observation of ultra-structure of cardiac TJs with transmission electron microscopy. There were clear TJs between coronary endothelial cells of mouse hearts. IR caused the collapse of TJs whereas IPC sustained the structure of TJs. IR increased extravascular EBA content in the heart and myocardial edema but decreased the expression of ZO-2 in the cytoskeleton. IPC maintained the structure of TJs. Cardiac EBA content and edema were reduced in IPC hearts. IPC enhanced the translocation of ZO-2 from cytosol to cytoskeleton. In conclusion, TJs occur in

    Starting from the simplified linear combination of atomic orbitals method in combination with first-principles calculations, we construct a tight-binding (TB) model in the two-centre approximation for borophene and hydrogenated borophene (borophane). The Slater and Koster approach is applied to calculate the TB Hamiltonian of these systems. We obtain expressions for the Hamiltonian and overlap matrix elements between different orbitals for the different atoms and present the SK coefficients in a nonorthogonal basis set. An anisotropic Dirac cone is found in the band structure of borophane. We derive a Dirac low-energy Hamiltonian and compare the Fermi velocities with that of graphene.

    Tight glycemic control in the ICU has been shown to reduce mortality in some but not all prospective randomized control trials. Confounding the interpretation of these studies are differences in how the control was achieved and underlying incidence of hypoglycemia, which can be expected to be affected by the introduction of continuous glucose monitoring (CGM). In this issue of Critical Care, a consensus panel provides a list of the research priorities they believe are needed for CGM to become routine practice in the ICU. We reflect on these recommendations and consider the implications for using CGM today.

    Full Text Available Introduction. An analysis of the drinking water quality and the degree of access to water supply and sewerage system in Poland was conducted. Materials and methods. Method of analysis of secondary statistical data was applied, mostly based on data available in the materials of the Central Statistical Office in Warsaw, the Waterworks Polish Chamber of Commerce in Bydgoszcz and the National Water Management in Warsaw. Result and discussion. 60 % of Poles do not trust to drink water without prior boiling. Water flowing from the taps, although widely available, is judged to be polluted, with too much fluorine or not having the appropriate consumer values (colour, smell and taste. The current water treatment systems can however improve them, although such a treatment, i.e. mainly through chlorination of water, deteriorates its quality in relation to pure natural water. The result is that fewer and fewer Poles drink water directly from the tap. They also less and less use tap water to cook food for which the bottled water is trusted more. Reason for that is that society does not trust the safety of the water supplied by the municipal water companies. The question thus is: Are they right? Tap water in Poland meets all standards since it is constantly monitored by the water companies and all relevant health services. Tap water supplied through the water supply system can be used without prior boiling. Studies have shown that only the operating parameters of water, suc h as taste, odour and hardness, are not satisfactory everywhere, different in each city, and sometimes in different districts of cities, often waking thoughts among users about its inappropriateness. The lowered water value can be easily improved at home through the use of filters. In conclusion, due to constant monitoring and investment in upgrading treatment processes, the quality of tap water has improved significantly in the last years. Conclusion. The results first allow assessing the

    Dysentery as infective and contagious disease is registered by all EU and EFTA countries only as shigellosis according to etiological classification of the infectious diseases. The cases are also registered by ECDC. According to ECDC Report for 2006-2008 the incidence rate in Poland Sanitary Stations, send to the National Register of Infectious Diseases, evaluated, calculated and published by Department of Epidemiology National Institute of Public Health (NIZP-PZH) in Annual Bulletin "Infections and Intoxications in Poland in 2010", Warsaw NIZP-PZH and GIS (Chief Sanitary Inspectorate ) 2010. Laboratory data were collected as reports from all Regional Sanitary Laboratories send to NIZP-PZH Department of Bacteriology, data from epidemiological investigation of outbreaks including data from identification of Shigella strains obtained from the Reference Laboratory for Gram-negative Bacilli of NIZP-PZH Bacteriology Department. In 2010 thirty cases of shigellosis were registered (incidence was 0.08/100 000 inhabitants) the same number of cases and incidence was observed in 2009, nearly the same in 2008 - 33 cases (incidence 0.09). The numbers were lower than the median in 2004-2008 (64 cases, incidence 0.17/100 000). According to laboratory reports in all 16 Regional Sanitary Stations only 14 persons were Shigella positive, in spite that more than 600 000 were examined: 10 persons were infected by S. sonnei, 4 by S. flexneri. Only one strain of S. sonnei was isolated from a patient with diarrhea. It was in the Regional Sanitary Station laboratory of the małopolskie voievodeshaft. No one strain of S. boydii or S. dysenteriae was isolated. Most of the dysentery cases were examined by other laboratories than laboratories of sanitary epidemiological service. The obligation of private payment for bacteriological examination of suspected cases is one of reason that patient is treated with antibacterial drugs without determination of etiological agent of the infection.

    In 1997, a new energy law was passed in Poland. An important element of the law is that local energy is made obligatory. The law describes obligatory tasks and procedures for the Polish municipalities related to planning and organisation of the energy sector. With the objective of supporting the Polish municipalities in their obligations according to the energy law, the project 'Energy Planning in Poland at Municipal Level - Support to Decision Makers' was launched. As part of the project, Municipal Guideline Reports have been elaborated for three model municipalities. These guidelines present the basis for energy supply plans in the three municipalities. For the city of Legionowo, the following was recommended: 1. The planning processes initiated during the project should be continued/followed up, 2. Master Plan for the district heating system should be prepared, 3. The possibilities of establishment of a major natural gas-fired CHP plant of the combined cycle type should be investigated. The present report describes the electricity market in Poland, the market in which a CHP plant in Legionowo will have to operate. Furthermore the report presents the results of the feasibility analysis carried out for a new CHP plant in Legionowo. (BA)

    Barsanti, P.; Di Palo, L.; Grimaldi, G.

    1988-01-01

    In 1987 the local leak rate test (LLRT) results of the primary containment were revised, with the following main goals: to highlight recurring problems, leading to lack of leak tightness of the primary containment; to individuate the pertinent degradation mechanisms; to assess the corrective actions already implemented and to plan further improvements, if necessary; and to optimize the preventive maintenance program on the containment, particularly the inspection frequency. All LLRTs in the past operating period, both before (as found) and after (as left) maintenance were analyzed, in terms of leakage rate and equivalent area of leak, for each penetration. Corrective actions already implemented included replacement of some valves with better quality type one, passivation of the carbon steel pipes and improvement of the pertinent surveillance procedures. Long term corrective actions, now under consideration, will include the following: more extensive passivation of pipes, carrying humid air, so that oxidation could be drastically reduced; better chemistry control in fluid systems; extensive replacement of the butterfly valves presently used; implementation of the LLRT practice, such to quantitatively measure the leakage rate, also in presence of large leak; and reduction of the time interval between periodical tests, on the basis of the results of the previous ones. Following these guidelines, future overall leakage tests would be performed in as found condition, aimed to verify the effectiveness of the entire maintenance and testing program of the primary containment and of its capability to maintain leak tightness during the time between two subsequent tests

    2017-09-01

    Full Text Available The sparsity regularization approach, which assumes that the image of interest is likely to have sparse representation in some transform domain, has been an active research area in image processing and medical image reconstruction. Although various sparsifying transforms have been used in medical image reconstruction such as wavelet, contourlet, and total variation (TV etc., the efficiency of these transforms typically rely on the special structure of the underlying image. A better way to address this issue is to develop an overcomplete dictionary from the input data in order to get a better sparsifying transform for the underlying image. However, the general overcomplete dictionaries do not satisfy the so-called perfect reconstruction property which ensures that the given signal can be perfectly represented by its canonical coefficients in a manner similar to orthonormal bases, resulting in time consuming in the iterative image reconstruction. This work is to develop an adaptive wavelet tight frame method for magnetic resonance image reconstruction. The proposed scheme incorporates the adaptive wavelet tight frame approach into the magnetic resonance image reconstruction by solving a l0-regularized minimization problem. Numerical results show that the proposed approach provides significant time savings as compared to the over-complete dictionary based methods with comparable performance in terms of both peak signal-to-noise ratio and subjective visual quality.

    The particle in a periodic potential is an important topic in an undergraduate quantum mechanics curriculum and a stepping stone on the way to more advanced topics, such as courses on interacting electrons in crystalline solids, and graduate-level research in solid-state and condensed matter physics. The interacting many-body phenomena are usually described in terms of the second quantized lattice Hamiltonians which treat single-particle physics on the level of tight-binding approximation and add interactions on top of it. The aim of this paper is to show how the tight-binding tunneling amplitude can be related to the strength of the periodic potential for the case of a cosine potential used in the burgeoning field of ultracold atoms. We show how to approach the problem of computing the tunneling amplitude of a deep lattice using the JWKB (Jeffreys-Wentzel-Kramers-Brillouin, also known as semiclassical) approximation. We also point out that care should be taken when applying the method of the linear combination of atomic orbitals (LCAO) in an optical lattice context. A summary of the exact solution in terms of Mathieu functions is also given.

    DARYLE H BUSCH RICHARD S GIVENS

    2004-12-10

    Much of the earth's pollution involves compounds of the metallic elements, including actinides, strontium, cesium, technetium, and RCRA metals. Metal ions bind to molecules called ligands, which are the molecular tools that can manipulate the metal ions under most conditions. This DOE-EMSP sponsored program strives (1) to provide the foundations for using the most powerful ligands in transformational separations technologies and (2) to produce seminal examples of their applications to separations appropriate to the DOE EM mission. These ultra tight-binding ligands can capture metal ions in the most competitive of circumstances (from mineralized sites, lesser ligands, and even extremely dilute solutions), but they react so slowly that they are useless in traditional separations methodologies. Two attacks on this problem are underway. The first accommodates to the challenging molecular lethargy by developing a seminal slow separations methodology termed the soil poultice. The second designs ligands that are only tight-binding while wrapped around the targeted metal ion, but can be put in place by switch-binding and removed by switch-release. We envision a kind of molecular switching process to accelerate the union between metal ion and tight-binding ligand. Molecular switching processes are suggested for overcoming the slow natural equilibration rate with which ultra tight-binding ligands combine with metal ions. Ligands that bind relatively weakly combine with metal ions rapidly, so the trick is to convert a ligand from a weak, rapidly binding species to a powerful, slow releasing ligand--during the binding of the ligand to the metal ion. Such switch-binding ligands must react with themselves, and the reaction must take place under the influence of the metal ion. For example, our generation 1 ligands showed that a well-designed linear ligand with ends that readily combine, forms a cyclic molecule when it wraps around a metal ion. Our generation 2 ligands are

    2010-01-01

    America has begun the development of a new heavy lift rocket which will enable humans to return to the moon and reach even farther destinations. Five decades ago, the National Aeronautics and Space Administration designed a system (called Saturn/Apollo) to carry men to the moon and back; the rocket which boosted them to the moon was the Saturn V. Saturn V was huge relative to contemporary rockets and is still the largest rocket ever launched. The new moon rocket is called Ares V. It will insert 40% more payload into low earth orbit than Saturn V; and after docking with the crew spacecraft, it will insert 50% more payload onto the translunar trajectory than Saturn V. The current design of Ares V calls for two liquid-fueled stages and 2 "strap-on" solid rockets. The solid rockets are extended-length versions of the solid rockets used on the Shuttle. The diameter of the liquid stages is at least as large as the first stage of the Saturn V; the height of the lower liquid stage (called the core stage) is longer than the external tank of the Shuttle. Huge rockets require huge infrastructure and, during the Saturn/Apollo era, America invested significantly in manufacturing, assembly and launch facilities which are still in use today. Since the Saturn/Apollo era, America has invested in additional infrastructure for the Shuttle program. Ares V must utilize this existing infrastructure, with reasonable modifications. Building a rocket with 50% more capability in the same buildings, testing it in the same test stands, shipping on the same canals under the same bridges, assembling it in the same building, rolling it to the pad on the same crawler, and launching it from the same launch pad is an engineering and logistics challenge which goes hand-in-hand with designing the structure, tanks, turbines, engines, software, etc. necessary to carry such a large payload to earth orbit and to the moon. This paper quantitatively discusses the significant "tight fits" that are

    The authors describe systems developed in Poland for the computerised assessment of coal reserves. The Zasoby system calculates coal reserves and evaluates selected natural properties of seams within the boundaries of an arbitrary mining property, based entirely on exploratory borehole data. The IOS-10 system is based on the Polish data bank for bituminous coal deposits. It is not suitable for use in mine design procedures, but is widely used for the statistical recording of reserves in areas currently being worked. The major part of the paper is devoted to a description of the Geo-3 system, used for the computation of reserves in prospective areas from borehole data, as well as in active mining areas or partially worked-out deposits. The computation method is explained and examples of the results obtained are given.

    When evaluating the quality of Rheumatology specialty training, it can be useful to explore similarities and differences between countries. In this article we compare the training in the UK and Poland. The two training programmes are similar in length and in the competencies that must be achieved, although they do have significant differences in the way the training is structured. The UK-based system is more out-patient based, which can be advantageous, as after completion of training the doctor is more confident in treating common rheumatological problems. On the other hand, having exposure to paediatric rheumatology and orthopaedics like one has in Polish-based training, despite a short placement time, is definitely beneficial for the trainee in gaining all-round knowledge. In conclusion, each system has its merits and can be further enhanced by observing how junior doctors are sub-speciality trained in different countries.

    Full Text Available The problems presented in the text refer to the education of convicts in Poland. It has been based on current Polish legal regulations, statistical data and specialist literature. The problems which refer to the education of convicts in Poland are regulated by the Act of 6th June 1997, the Executive Penal Code, the Act on the Education System and executive acts to the above-mentioned regulations. The current situation in the labour market requires people to acquire education and to improve their qualifications. People without education, who are excluded from the access to professional development and in-service training, find themselves in an extremely difficult situation. The lack of qualification and vocational skills usually leads to exclusion from the labour market. People who serve their sentences in prisons find themselves in a particularly difficult situation, because their lack of education may push them back into crime. A very positive tendency that may be observed in Poland is a growing demand for prison education. Convicts may acquire knowledge and raise their qualifications at various levels and in various fields. They may follow the curricula at the level of a primary or secondary school; they may pass their Matura certificate and, after the consent of relevant authorities, they can continue their education at the university level. Convicts may also learn a new profession, change their professional qualifications or acquire new additional skills during specialist courses. The qualifications acquired in this way shall meet current demand in the labour market, and convicts may find employment after they leave prisons. Education allows them to improve their self-esteem and self-reliance, to catch up with any deficiencies and to work on their self-discipline. At the same time, education offers opportunities to expand knowledge, to return to the society and to the labour market. It is important for convicts to obtain opportunities for

    Full Text Available In Poland, as in other European Union countries, the project finance structure is used to finance investments in the field of energy. This method investment financing is often used in the world. The upward trend inhibition in recent periods has been due to the global financial crisis and financial instability in the euro zone. On account of the necessity to develop the energy infrastructure associated with renewable sources, the considerable strengthening in the use of project finance techniques can be expected. The particular progression may be observed in the case of public-private partnership (ppp, where public investments are carried out by private companies. Companies, in case of investment realization in the field of ppp, almost always use project finance, because it is a beneficial way to separate the risks associated with an investment from the balance sheet of the compa-ny.

    Shale-gas formations are known to be associated with source rocks. Major oil and gas provinces in Poland have been reviewed with respect to source rock quality using a petroleum play concept. As a result, three potential shale-gas plays were distinguished: (1) Silurian of the western slope of the East European Craton, (2) Carboniferous of the Fore-Sudetic Monocline, (3) Miocene of the Carpathian Foredeep Basin. Only the Silurian of the East European Craton and the Carboniferous of the Fore-Sudetic Monocline were further evaluated to delineate prospective areas as the Carpathian Foredeep Basin was not available for exploration license. The screening criteria used in this evaluation were main geochemical parameters: total organic carbon (TOC), thermal maturity and kerogen type, as well as depth, thickness and lateral extent of potential organic-rich shale formations. Three prospective areas have been delineated within the Silurian of the East European Craton: (1) Baltic Basin, (2) Podlasie Depression and (3) Lublin Basin, whereas one prospective area was high graded in the Carboniferous of the Fore-Sudetic Monocline. This evaluation was carried out based on the existing data gathered for the most part by the Polish Geological Institute. The four shale-gas prospective areas have been characterized using lithology and depositional environments, geochemical data, structural evolution and burial history of Silurian and Carboniferous strata, as well as thickness of the organic-rich shales. Published data concerning successful shale gas plays in the U.S. were collected to make a comparison with the prospective shale-gas formations of Poland. The Polish government granted several exploration concessions over the last two years in each of the prospective areas. In the initial stage of exploration activities, EurEnergy have been focused on acquisition of more detailed geochemical data (based on existing core samples), preparation of geological and structural studies as well

This paper is an introduction to more detailed studies of the epidemiological situation of selected infectious diseases and summarizes the results of the surveillance of infectious diseases in Poland in 2015. References to epidemiological situation in other countries are limited to situations that may affect current or potential occurrence of the disease in Poland. The main source of epidemiological information for this summary is the data from the reports of the State Sanitary Inspection included in the annual bulletins “Infectious Diseases and Poisonings in Poland in 2015” and “Vaccination in Poland in 2015” (1, 2). The epidemiological situation of particular diseases is further elaborated in the Epidemiological Chronicle of the same issue of the Epidemiological Review. Data on deaths are based on the presentation of the Demographic and Labor Market Department of the Central Statistical Office on deaths from infectious and parasitic diseases registered in Poland in 2015 and earlier. For a long time, the most common diseases among epidemiological surveillance it is upper respiratory tract infections classified as “influenza and suspected influenza”. In 2015, the number of cases was 3,843,438 (9 994,7 / 100,000). As to compare with the 2014’s incidence, this was an increase of 22.6%. In 2015, incidence of intestinal infections with etiology of salmonella increased by 2.8% compared to the previous year, but compared to the median of 2009-2013 was 2.5% lower. A serious epidemiological problem is a strong upward trend in nosocomial infections including infections caused by

    Full Text Available Ozone in the lower part of the atmosphere (troposphere, strong photochemical oxidant, is not directly emitted to the atmosphere but formed through a series of complex reactions. Ozone concentrations depends on ozone precursors air contamination (mainly nitrogen dioxide and non-methane volatile organic compounds and meteorological conditions (temperature and solar radiation. The main sectors emitted ozone precursors are road transport, power and heat generation plants, household (heating, industry, and petrol storage and distribution. Ozone and some of its precursors are also transported long distances in the atmosphere and are therefore considered a transboundary problem. As a result, the ozone concentrations are often low in busy urban areas and higher in suburban and rural areas. Nowadays, instead of particulate matter, ozone is one of the most widespread global air pollution problems. In and around urban areas, relatively large gradients of ozone can be observed. Because of its high reactivity in elevated concentrations ozone causes serious health problems and damage to ecosystems, agricultural crops and materials. Main ill-health endpoints as a results of ozone concentrations can be characterised as an effect of pulmonary and cardiovascular system, time morbidity and mortality series, development of atherosclerosis and asthma and finally reduction in life expectancy. The associations with increased daily mortality due to ozone concentrations are confirmed by many researches and epidemiological studies. Estimation of the level selected ill-health endpoints (mortality in total and due to cardiovascular and respiratory causes as a result of the short-term ozone exposure in Poland was the main aim of the project. Final results have been done based on estimation method elaborated by WHO, ozone measurements from National Air Quality Monitoring System and statistical information such as mortality rate and populations. All analysis have been done in

    Full Text Available The main purpose of this work is to analyse the phenomenon of enterprises’ bankruptcy in Poland in 2004-2013 and attempt to build regression models defining the relationship between the number of bankrupted companies and selected macroeconomic parameters of the national economy. The analysis is based on Coface Poland reports presenting the phenomenon of bankruptcy in Poland of branches, provinces, legal forms of companies and types of bankruptcy proceedings. Studies have shown that the greatest risk of bankruptcy refers to metals production and fabricated metal products enterprises, manufacture of food products and beverages, wholesale trade, construction, micro and small enterprises, enterprises under the age of 10 years and companies from Mazovia region, Silesia and Lower Silesia. The estimated parameters of the regression models showed that the number of bankruptcies in Poland is strongly determined i.a. by the number of registered companies, GDP growth, dynamics of changes in fixed capital formation and changes in foreign exchange rates.

  13. Multiple regions of Crumbs3 are required for tight junction formation in MCF10A cells.

    Fogg, Vanessa C; Liu, Chia-Jen; Margolis, Ben

    2005-07-01

    The formation and maintenance of tight junctions is essential for the development of epithelial cell polarity. Recently, a number of conserved polarity-regulating proteins have been shown to localize to epithelial tight junctions, and to play a role in the regulation of tight junction formation. The Crumbs3/PALS1/PATJ protein complex localizes at epithelial tight junctions and interacts with the polarity-regulating protein complex of Par6/Par3/aPKC. Overexpression of Crumbs3 in MDCKII cells leads to a delay in tight junction formation in these cells, suggesting a role in the regulation of tight junction development. Here we report new evidence that Crumbs3 indeed plays an essential role in tight junction formation. Mammary MCF10A cells express little endogenous Crumbs3 and fail to form tight junctions when grown under standard tissue culture conditions. The staining pattern of ZO-1, a tight junction marker, is fragmented, and other tight junction markers show either fragmented junctional expression or diffuse cytoplasmic staining. Expression of exogenous Crumbs3 induces the formation of tight junction structures marked by smooth, continuous ZO-1 staining at apical cell-cell junctions. A number of other tight junction markers, including claudin-1 and occludin, are also recruited to these junctions. Analysis by transmission electron microscopy and measurements of the transepithelial electrical resistance confirm that these structures are functional tight junctions. Mutations in either the Crumbs3 PDZ binding motif or the putative FERM binding motif lead to defects in the ability of Crumbs3 to promote tight junction development. Our results suggest that Crumbs3 plays an important role in epithelial tight junction formation, and also provide the first known functional role for the mammalian Crumbs FERM binding domain.

  20. Revenue Risk of U.S. Tight-Oil Firms

    2016-10-01

    Full Text Available American U.S. crude oil prices have dropped significantly of late down to a low of less than $30 a barrel in early 2016. At the same time price volatility has increased and crude in storage has reached record amounts in the U.S. America. Low oil prices in particular pose quite a challenge for the survival of U.S. America’s tight-oil industry. In this paper we assess the current profitability and future prospects of this industry. The question could be broadly stated as: should producers stop operation immediately or continue in the hope that prices will rise in the medium term? Our assessment is based on a stochastic volatility model with three risk factors, namely the oil spot price, the long-term oil price, and the spot price volatility; we allow for these sources of risk to be correlated and display mean reversion. We then use information from spot and futures West Texas Intermediate (WTI oil prices to estimate this model. Our aim is to show how the development of the oil price in the future may affect the prospective revenues of firms and hence their operation decisions at present. With the numerical estimates of the model’s parameters we can compute the value of an operating tight-oil field over a certain time horizon. Thus, the present value (PV of the prospective revenues up to ten years from now is $37.07/bbl in the base case. Consequently, provided that the cost of producing a barrel of oil is less than $37.07 production from an operating field would make economic sense. Obviously this is just a point estimate. We further perform a Monte Carlo (MC simulation to derive the risk profile of this activity and calculate two standard measures of risk, namely the value at risk (VaR and the expected shortfall (ES (for a given confidence level. In this sense, the PV of the prospective revenues will fall below $22.22/bbl in the worst 5% of the cases; and the average value across these worst scenarios is $19.77/bbl. Last we undertake two

    Highlights: Black-Right-Pointing-Pointer Cardiac tight junctions are present between coronary endothelial cells. Black-Right-Pointing-Pointer Ischemic preconditioning preserves the structural and functional integrity of tight junctions. Black-Right-Pointing-Pointer Myocardial edema is prevented in hearts subjected to ischemic preconditioning. Black-Right-Pointing-Pointer Ischemic preconditioning enhances translocation of ZO-2 from cytosol to cytoskeleton. -- Abstract: Ischemic preconditioning (IPC) is one of the most effective procedures known to protect hearts against ischemia/reperfusion (IR) injury. Tight junction (TJ) barriers occur between coronary endothelial cells. TJs provide barrier function to maintain the homeostasis of the inner environment of tissues. However, the effect of IPC on the structure and function of cardiac TJs remains unknown. We tested the hypothesis that myocardial IR injury ruptures the structure of TJs and impairs endothelial permeability whereas IPC preserves the structural and functional integrity of TJs in the blood-heart barrier. Langendorff hearts from C57BL/6J mice were prepared and perfused with Krebs-Henseleit buffer. Cardiac function, creatine kinase release, and myocardial edema were measured. Cardiac TJ function was evaluated by measuring Evans blue-conjugated albumin (EBA) content in the extravascular compartment of hearts. Expression and translocation of zonula occludens (ZO)-2 in IR and IPC hearts were detected with Western blot. A subset of hearts was processed for the observation of ultra-structure of cardiac TJs with transmission electron microscopy. There were clear TJs between coronary endothelial cells of mouse hearts. IR caused the collapse of TJs whereas IPC sustained the structure of TJs. IR increased extravascular EBA content in the heart and myocardial edema but decreased the expression of ZO-2 in the cytoskeleton. IPC maintained the structure of TJs. Cardiac EBA content and edema were reduced in IPC hearts. IPC

  2. Trends in drug delivery through tissue barriers containing tight junctions.

    A limitation in the uptake of many drugs is the restricted permeation through tissue barriers. There are two general ways to cross barriers formed by cell layers: by transcytosis or by diffusion through the intercellular space. In the latter, tight junctions (TJs) play the decisive role in the regulation of the barrier permeability. Thus, transient modulation of TJs is a potent strategy to improve drug delivery. There have been extensive studies on surfactant-like absorption enhancers. One of the most effective enhancers found is sodium caprate. However, this modulates TJs in an unspecific fashion. A novel approach would be the specific modulation of TJ-associated marvel proteins and claudins, which are the main structural components of the TJs. Recent studies have identified synthetic peptidomimetics and RNA interference techniques to downregulate the expression of targeted TJ proteins. This review summarizes current progress and discusses the impact on TJs' barrier function.

    Multiplicity is a key statistic for understanding the formation of very low mass (VLM) stars and brown dwarfs. Currently, the separation distribution of VLM binaries remains poorly constrained at small separations (candidates from a library of 738 spectra from the SpeX Prism Spectral Libraries. We present twelve new binary candidates, confirm two previously reported candidates and rule out other two previously reported candidates. All of our candidates have primary and secondary spectral types between M7-L7 and L8-T8 respectively. We find that blue L dwarfs and subdwarfs are contaminants in our sample and propose a method for segregating these sources. If confirmed by follow-up observations, these systems may potentially add to the growing list of tight separation binaries, giving further insight into brown dwarf formation scenarios.

    Performance guarantees for recovery algorithms employed in sparse representations, and compressed sensing highlights the importance of incoherence. Optimal bounds of incoherence are attained by equiangular unit norm tight frames (ETFs). Although ETFs are important in many applications, they do not exist for all dimensions, while their construction has been proven extremely difficult. In this paper, we construct frames that are close to ETFs. According to results from frame and graph theory, the existence of an ETF depends on the existence of its signature matrix, that is, a symmetric matrix with certain structure and spectrum consisting of two distinct eigenvalues. We view the construction of a signature matrix as an inverse eigenvalue problem and propose a method that produces frames of any dimensions that are close to ETFs. Due to the achieved equiangularity property, the so obtained frames can be employed as spreading sequences in synchronous code-division multiple access (s-CDMA) systems, besides compressed sensing.

    We have continued high gradient R&D of ICHIRO 9-cell cavities at KEK. ICHIRO 9-cell cavity #5 (I9#5) that has no end groups on beam tube to focus on high gradient sent to Jlab as S0 tight loop study. Surface treatments and vertical test were repeated 3 times at Jlab, and then I9#5 sent back to KEK. We also repeated surface treatments and test at KEK. Maximum gradients were 36.5MV/m at Jlab, and 33.7MV/m at KEK so far. Now we are struggling with the puzzle why the results of singles do not work well on 9-cell cavities.

We characterize when...... such systems form tight frames, and when two GTI Bessel systems form dual frames for L2(G). In particular, this offers a unified approach to the theory of discrete and continuous frames and, e.g., yields well known results for discrete and continuous Gabor and wavelet systems....

  7. Zonulin, regulation of tight junctions, and autoimmune diseases.

    Recent studies indicate that besides digestion and absorption of nutrients and water and electrolytes homeostasis, another key function of the intestine is to regulate the trafficking of environmental antigens across the host mucosal barrier. Intestinal tight junctions (TJs) create gradients for the optimal absorption and transport of nutrients and control the balance between tolerance and immunity to nonself antigens. To meet diverse physiological challenges, intestinal epithelial TJs must be modified rapidly and in a coordinated fashion by regulatory systems that orchestrate the state of assembly of the TJ multiprotein network. While considerable knowledge exists about TJ ultrastructure, relatively little is known about their physiological and pathophysiological regulation. Our discovery of zonulin, the only known physiologic modulator of intercellular TJs described so far, has increased our understanding of the intricate mechanisms that regulate the intestinal epithelial paracellular pathway and has led us to appreciate that its upregulation in genetically susceptible individuals leads to autoimmune diseases. © 2012 New York Academy of Sciences.

  8. ADVANCED FRACTURING TECHNOLOGY FOR TIGHT GAS: AN EAST TEXAS FIELD DEMONSTRATION

    The primary objective of this research was to improve completion and fracturing practices in gas reservoirs in marginal plays in the continental United States. The Bossier Play in East Texas, a very active tight gas play, was chosen as the site to develop and test the new strategies for completion and fracturing. Figure 1 provides a general location map for the Dowdy Ranch Field, where the wells involved in this study are located. The Bossier and other tight gas formations in the continental Unites States are marginal plays in that they become uneconomical at gas prices below $2.00 MCF. It was, therefore, imperative that completion and fracturing practices be optimized so that these gas wells remain economically attractive. The economic viability of this play is strongly dependent on the cost and effectiveness of the hydraulic fracturing used in its well completions. Water-fracs consisting of proppant pumped with un-gelled fluid is the type of stimulation used in many low permeability reservoirs in East Texas and throughout the United States. The use of low viscosity Newtonian fluids allows the creation of long narrow fractures in the reservoir, without the excessive height growth that is often seen with cross-linked fluids. These low viscosity fluids have poor proppant transport properties. Pressure transient tests run on several wells that have been water-fractured indicate a long effective fracture length with very low fracture conductivity even when large amounts of proppant are placed in the formation. A modification to the water-frac stimulation design was needed to transport proppant farther out into the fracture. This requires suspending the proppant until the fracture closes without generating excessive fracture height. A review of fracture diagnostic data collected from various wells in different areas (for conventional gel and water-fracs) suggests that effective propped lengths for the fracture treatments are sometimes significantly shorter than those

    Unconventional gas refers to natural gas contained in difficult-to-produce formations that require special drilling and completion techniques to achieve commercial production. It includes tight gas, coal seams, organic shales, and gas hydrates. Canada's vast unconventional gas resource is becoming an increasingly important part of the country's gas supply. The emergence of unconventional gas production in Canada over the past several years has made the unconventional increasingly conventional in terms of industry activity. It was suggested that in order to realize the potential for unconventional gas in Canada, all stakeholders should engage to ensure the development is environmentally responsible. Unconventional gas accounts for nearly one third of U.S. gas production. It also accounts for nearly 5 Bcf per day and growing. The impetus to this sudden growth has been the gradual and increasing contribution of tight sands and limes to Canadian production, which accounts for more than 4 Bcf per day. Coalbed methane (CBM) is at 0.5 Bcf per day and growing. In response to expectations that CBM will reach 2 to 3 Bcf per day over the next 2 decades, Canadian producers are placing more emphasis on unconventional resource plays, including organic shales and gas hydrates. As such, significant growth of unconventional gas is anticipated. This growth will be facilitated by the adoption of U.S..-developed technologies and new Canadian technologies. It was suggested that research and development will be key to unlocking the unconventional gas potential. It was also suggested that the already existing, strong regulatory structure should continue in order to accommodate this growth in a sustainable manner. figs

    Claudin-5 is a tight junction (TJ) protein which limits the diffusion of small hydrophilic molecules. Thus, it represents a potential pharmacological target to improve drug delivery to the tissues protected by claudin-5-dependent barriers. Sodium caprate is known as an absorption enhancer which opens the paracellular space acting on TJ proteins and actin cytoskeleton. Its action on claudin-5 is not understood so far. Epithelial and endothelial systems were used to evaluate the effect of caprate on claudin-5 in TJ-free cells and on claudin-5 fully integrated in TJ. To this aim, confocal microscopy on live and fixed cells and isolated mouse brain capillaries, Western blotting and permeability assays were employed. Caprate reversibly reduced claudin-5 trans-interactions in TJ-free human embryonic kidney-293 cells expressing claudin-5-YFP. It decreased the membranous claudin-5 and the F-actin content in Madin-Darby canine kidney-II cells expressing Flag-claudin-5, thereby increasing the permeability to the small molecule lucifer yellow. Interestingly, zonula occludens protein 1 (ZO-1), which links transmembranous TJ proteins to the actin cytoskeleton, was not affected by caprate treatment. Similarly, endogenous claudin-5 in the membrane of brain endothelia was displaced together with F-actin, whereas ZO-1 remained unaffected. Caprate transiently opens the paracellular space, reducing the intercellular claudin-5/claudin-5 interactions and the polymerized actin at the perijunctional region of endothelial and epithelial cells. In conclusion, the study further elucidates the cellular effects of caprate at the tight junctions.

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

    Full Text Available The New Public Management movement regards citizens as customers and, accordingly, focuses on the quality of services provided by public-sector organizations. Since this approach negatively affected democratic values, there has been a shift of the focus from consumer satisfaction and quality of services to quality of governance. The latter implies the improvement of the relationship between government and citizens as active members of the community. Over the last twenty years, participatory budgeting (PB has become a popular form of co-production intended to improve the quality of local governance. The aim of the article is to provide a comparative analysis of the use and role of PB in Croatia, Poland and Slovakia and to identify the models of PB used in selected countries. In order to compare the case studies of municipalities in selected countries, a qualitative analysis has been used and the classification of PB models applied. Most analyzed local units use the “Porto Alegre adapted for Europe” model, but the “Consultation on public finances”, “Representation of Organized Interest” and “Proximity participation” models are also represented. The main findings are that PB indeed enables better allocation of public sources according to citizens’ needs (various public services were delivered following the trend of social innovation and co-creation, but the problem lies in the low amount assigned for PB from public budgets and the relatively low interest of citizens to participate in the PB processes. PB might also bring certain risks linked with its implementation, e.g. misuse of the idea for political reasons or additional costs of projects delivered in the PB process.

    In Poland, nuclear medicine (NM) has been an independent specialty since 1988. At the end of 2013, the syllabus for postgraduate specialization in NM has been modified to be in close accordance with the syllabus approved by the European Union of Medical Specialists and is expected to be enforced before the end of 2014. The National Consultant in Nuclear Medicine is responsible for the specialization program in NM. The Medical Center of Postgraduate Training is the administrative body which accepts the specialization programs, supervises the training, organizes the examinations, and awards the specialist title. Specialization in NM for physicians lasts for five years. It consists of 36 months of training in a native nuclear medicine department, 12 months of internship in radiology, 3 months in cardiology, 3 months in endocrinology, 3 months in oncology, and 3 months in two other departments of NM. If a NM trainee is a specialist of a clinical discipline and/or is after a long residency in NM departments, the specialization in NM can be shortened to three years. During the training, there are obligatory courses to be attended which include the elements of anatomy imaging in USG, CT, and MR. Currently, there are about 170 active NM specialists working for 38.5 million inhabitants in Poland. For other professionals working in NM departments, it is possible to get the title of a medical physics specialist after completing 3.5 years of training (for those with a master's in physics, technical physics or biomedical engineering) or the title of a radiopharmacy specialist after completing 3 years of training (for those with a master's in chemistry or biology). At present, the specialization program in NM for nurses is being developed by the Medical Centre of Postgraduate Education.

    This Report is a result of the Polish Nuclear Physics Network (PNPN) action having as objective the mapping study of the basic and applied research in this domain in Poland. In the often employed slang it constitutes one of the '' deliverables '' of the EWON (East-West Outreach) Network, operating within the I3- (Integrated Infrastructure Initiative) EURONS, one of the Nuclear Physics projects in the Six Framework Programme (FP6). However, although prepared within the nuclear structure EURONS framework, this mapping study also reports on the activities in the hadron physics in Poland (organized in the FP6 within a second Nuclear Physics project I3-Hadron Physics) as well as in Nuclear Theory and Applications of Nuclear Physics. The Report contains references to activities and published papers from the last ten years: 1996 - 2006. In some cases also slightly older data are included, if necessary, for the completeness of the reported subjects. The Report is organized as follows. After the information on Polish Nuclear Physics Network (a part of the EWON Network), a few overview papers describe the main domains of the PNPN scientific activity. The contents of these papers were previously presented during the NuPECC meeting, held in Krakow June 9, 2006. A number (89) of more detailed contributions (together with appropriate references) emanating from various research groups follows the review articles. Some of the contributions provide concise summaries of wide research activities. Other authors preferred to report separately or individually on narrower topics. Most of the presented activities were conducted within the international collaborations. However, the adopted policy was that only Polish researchers are indicated as authors of the contributions, whereas the international collaborations are reflected by (all) authors of cited publications.

    Despite the long history of pertussis vaccination and high vaccination coverage in Poland and many other developed countries, pertussis incidence rates have increased substantially, making whooping cough one of the most prevalent vaccine-preventable diseases. Among the factors potentially involved in pertussis resurgence, the adaptation of the Bordetella pertussis population to country-specific vaccine-induced immunity through selection of non-vaccine-type strains still needs detailed studies. Multi-locus variable-number tandem repeat analysis (MLVA), also linked to MLST and PFGE profiling, was applied to trace the genetic changes in the B. pertussis population circulating in Poland in the period 1959-2013 versus country-specific vaccine strains. Generally, among 174 B. pertussis isolates, 31 MLVA types were detected, of which 11 were not described previously. The predominant MLVA types of recent isolates in Poland were different from those of the typical isolates circulating in other European countries. The MT27 type, currently predominant in Europe, was rarely seen and detected in only five isolates among all studied. The features of the vaccine strains used for production of the pertussis component of a national whole-cell diphtheria-tetanus-pertussis (DTP) vaccine, as studied by MLVA and MLST tools, were found to not match those observed in the currently circulating B. pertussis isolates in Poland. Differences traced by MLVA in relation to the MLST and PFGE profiling confirmed that the B. pertussis strain types currently observed elsewhere in Europe, even if appearing in Poland, were not able to successfully disseminate within a human population in Poland that has been vaccinated with a whole-cell pertussis vaccine not used in other countries.

    Full Text Available Background Recently, several studies have been conducted to determine the optimal strategy for intraoperative fluid replacement therapy in renal transplantation surgery. Since infusion of sodium bicarbonate as a buffer seems to be safer than other buffer compounds (lactate, gluconate, acetatethat indirectly convert into it within the liver, We hypothesized tight control of metabolic acidosis by infusion of sodium bicarbonate may improve early post-operative renal function in renal transplant recipients. Methods:120 patients were randomly divided into two equal groups. In group A, bicarbonate was infused intra-operatively according to Base Excess (BE measurements to achieve the normal values of BE (5 to +5 mEq/L. In group B, infusion of bicarbonate was allowed only in case of severe metabolic acidosis (BE [less than or equal to] 15 mEq/L or bicarbonate [less than or equal to] 10 mEq/L or PH [less than or equal to] 7.15. Minute ventilation was adjusted to keep PaCO2 within the normal range. Primary end-point was sampling of serum creatinine level in first, second, third and seventh post-operative days for statistical comparison between groups. Secondary objectives were comparison of cumulative urine volumes in the first 24 h of post-operative period and serum BUN levels which were obtained in first, second, third and seventh post-operative days. Results:In group A, all of consecutive serum creatinine levels were significantly lower in comparison with group B. With regard to secondary outcomes, no significant difference between groups was observed. Conclusion:Intra-operative tight control of metabolic acidosis by infusion of Sodium Bicarbonate in renal transplant recipients may improve early post-operative renal function.

    Full Text Available Introduction. In 2012, China became the largest spender in international tourism, benefiting many destinations worldwide. Even if for Poland it is not an important source market yet, the Polish authorities have undertaken some marketing activities in China. The main aim of the paper is to explore the profile, motivations, and perceptions of the Chinese tourists visiting Cracow. The secondary aim is to check the effectiveness of the marketing efforts dedicated to the Chinese market undertaken by Poland since 2010. Material and methods. Data for the study (n = 100 were collected using a paper survey in English carried out among mainland Chinese tourists in Cracow in 2015. Results. The Chinese usually visit Poland for the first time, often in transit. They are prompted by the information found online and by word of mouth. Their main reasons to come are tradition, culture, historical sites, landscapes, and low costs. These expectations are well fulfilled, and the tourists′ overall satisfaction is very high. The Chinese find Poland to be different from other Western European countries. For them, Poland is a remarkable, traditional, safe, and developing country. Yet, their knowledge about the destination is limited. The main problem encountered is the language barrier, both online and once on site. The marketing efforts undertaken by Poland in the Chinese market have had weak and ambivalent effects. Conclusions. In order to attract Chinese tourists, there is a need to intensify expenditure not only on promotion (mainly online but also on the removal of language-based communication problems. There is also scope for expanding the tourist offer dedicated to Chinese tourists - both in Poland and in cooperation with other Central European countries.

    Full Text Available In the global rankings of generalized trust, Poland occupies a lowly positon. Only 1/3 of Poles have a strong trust in strangers and roughly the same number believe that trust in business generally pays of. At the same tme, only half of them believe that a market economy based on private enterprise is the best economic system for the country. According to the literature review a major factor in the development of entrepreneurship is trust in other economic actors. The aim of the artcle is to present the relaton between trust and entrepreneurial actvites in Poland. In this paper the hypothesis was adopted that the level of trust in the public sphere, especially in business relatons in Poland, had an impact on the intensity of entrepreneurial actvites. The analysed period comprises the years from 2002 to 2016. The artcle presents changes in the potental for social trust, including trust in business. Indicators of confdence include the percentage of people that have trust in diferent actors in Poland. A further part of the paper is devoted to the phenomenon of entrepreneurship in Poland. Among the indicators of entrepreneurship are the number of newly registered and deregistered enttes, and enttes that are new or deregistered from the REGON register per 10 thousand of populaton. Moreover, the innovaton actvity of enterprises in Poland has been described. At the end, relatons between trust and entrepreneurial actvites in Poland were examined. The data was analysed statstcally with Pearson’s correlaton coefcients. The analysis of confdence and entrepreneurship is based mainly on the data published by the Polish Central Statstcal Ofce and Public Opinion Research Centre.

    Familial spastic paraplegia (FSP) (MIM No.18260) constitutes a clinically and genetically diverse group of disorders that share the primary feature of progressive, severe, lower extremity spasticity. FSP is classified according to the mode of inheritance and whether progressive spasticity occurs in isolation ({open_quotes}uncomplicated FSP{close_quotes}) or with other neurologic abnormalities ({open_quotes}complicated FSP{close_quotes}), including optic neuropathy, retinopathy, extrapyramidal disturbance, dementia, ataxia, ichthyosis, mental retardation, or deafness. Recently, autosomal dominant, uncomplicated FSP was shown to be genetically heterogeneous and tightly linked to a group of microsatellite markers on chromosome 14q in one large kindred. We examined 126 members of a non-consanguineous North American kindred of Irish descent. FSP was diagnosed in 31 living subjects who developed insidiously progressive gait disturbance between ages 12 and 35 years. Using genetic linkage analysis to microsatellite DNA polymorphisms, we showed that the FSP locus on chromosome 14q was exluded from linkage with the disorder in our family. Subsequently, we searched for genetic linkage between the disorder and microsatellite DNA polymorphisms spanning approximately 50% of the genome. We observed significantly positive, two-point maximum lod scores (Z) for markers on chromosome 15q: D15S128 (Z=9.70, {theta}=0.05), D15S165 (Z=3.30, {theta}=0.10), and UT511 (Z=3.86, {theta}=0.10). Our data clearly establishes that one locus for autosomal dominant, uncomplicated FSP is mapped to the pericentric region of chromosome 15q. Identifying genes responsible for chromosome 15q-linked and chromosome 14q-linked FSP will greatly advance our understanding of this condition and hopefully other inherited and degenerative brain and spinal cord disorders that are also characterized by axonal degeneration.

    Full Text Available Thallium concentrations in primary mineral commodities extracted in Poland and processed in high temperatures were determined by ICP-MS method. Samples of hard and brown coal, copper-silver and zinclead ores, argillaceous and calcareous rocks of different genesis and age were analyzed. The highest thallium concentrations occur in the zinc-lead ores, the average content being of 52.1 mg/kg. The copper ores contain in average 1.4 mg/kg of thallium. Hard coals from the Upper Silesian Coal Basin display higher thallium content than those exploited in the Lublin Coal Basin. Brown coals from Turow deposit distinguish by much higher values, 0.7 mg/kg Tl, than those from huge Bełchatów and smaller Konin-Turek region deposits. Average thallium concentrations in clays used for ceramic materials are lower than 1 mg/kg, except of Mio-Pliocene Slowiany deposit. The average content of thallium in the studied limestone and dolomite raw materials for cement, lime, and metallurgical flux, and refractories is very low in comparison to the average amounts in the world carbonate rocks.

    Radiological contamination of the environment is caused by nuclear activities on the globe: nuclear weapon tests and the Chernobyl accident. The transfer of radionuclides to the organism via ingestion is one of the sources of doses obtained by people. To assess the doses received by humans the intake of isotopes with daily diet was defined. The concentration of radionuclides in foodstuffs was determined. The network of Service for Measurement of Radioactive Contamination systematically controls all kinds of important agricultural products such as milk, meat, vegetables, fruit, cereals and forest products: mushrooms, blueberries etc. Measurement stations involved in food monitoring act within Sanitary-Epidemiological Stations, Veterinary Hygiene Units and Chemical-Agricultural Stations. All activities are co-ordinated by the Central Laboratory for Radiological Protection. The level of activity of caesium isotopes has regularly been monitored in collected samples originating from different administrative districts of Poland. Since 1994 the 134 Cs concentration has been below the detection limit. The activity of 137 Cs has been measured to determine long-term effect of the accident on the contamination of milk, meat and other foodstuffs. (orig.)

    Due to the energy crisis and the substantial rise in prices for mineral fuels and raw materials, along with searches for new energy sources, Poland (PNR) has begun works to restore and modernize those sources which in economic aspects were considered unprofitable, including low power hydroelectric power plants (GES). The development of such hydroelectric power plants must also be reevaluated from the ecological aspect. The ecological significance of a hydroelectric power plant lies in preventing a further lowering of the ground waters, the use of cascades for holding high water and for regulating its drainage with a threat of flooding, oxygen enrichment of water, prevention of erosion and silting of rivers, purification of water currents using protective grids with a favorable effect on the forests and the fishing industries located along the water currents used and the creation of conditions for relaxation, sports and turism. The restoration of hydraulic turbines is the basic condition for outfitting the hydroelectric power plants. Different designs for such turbines relative to the assigned capacity are examined.

    2016-12-01

    Full Text Available In this paper we introduce the research plan for the preparation of a searchable electronic repository of the earliest extant legal oaths from medieval Poland drawing on the expertise in historical corpus-building developed for the history of English. The oaths survive in the overwhelmingly Latin land books from the period between 1386 and 1446 for six localities Greater Poland, in which the land courts operated: Poznań, Kościan, Pyzdry, Gniezno, Konin and Kalisz. A diplomatic edition of the oaths was published in five volumes by Polish historical linguists (Kowalewicz & Kuraszkiewicz 1959–1966. The edition is the only comprehensive resource of considerable scope (over 6300 oaths from the years 1386–1446 for the study of the earliest attestations of the Polish language beyond glosses. Recognising some limitations, but most of all its unparalleled coverage of the coexistence of Latin and the vernacular, the ROThA project embarks on transforming the edition into an open up-to-date digital resource. We thus aim to facilitate research into the history of Polish and Latin as well as of the legal system and the related social and linguistic issues of the period.

    2015-06-01

    Full Text Available The changes in the Polish socio-economic system, initiated at the turn of 1989 and 1990, led to a systematic increase in the liberalization of economy and thereby the rise of the level of economic freedom. The aim of this paper is to examine the impact of the economic transition on the development of economic freedom in Poland. The analysis, carried out in the period 1995-2015, was conducted on the basis of the chain-linked Economic Freedom Index by the Fraser Institute and the Index of Economic Freedom of the Heritage Foundation and the Wall Street Journal. The analysis indicates that: (1 Poland cannot be considered as a country that is fully free economically, but the transition of its economic system has resulted in a rapid growth of economic freedom. (2 The impact of transition varies for different areas (sub-indices of the economy. (3 The European economic integration stimulated the increase of EFI, but the economic crisis did not decrease the level of economic freedom.

  11. Incremental versus Rapid Internationalisation of Firms: Results of Exploratory Investigation from Poland

    Krzysztof Wach

    2016-02-01

    Full Text Available Objective: The main objective of the article was to discuss the pace of internationalisation and its empirical verification among Polish firms taking into account two factors – strategic thinking and familiness of the studied firms. Research Design & Methods: The paper, apart from literature review and its critique, is based on results of a survey conducted among randomly selected 355 internationalised firms of different sizes from Poland. Findings: Firms having an internationalisation strategy rather internationalize faster than these lacking such a strategy, taking into account the average number of years elapses from its founding to the first internationalisation. The empirical results show that the average time of internationalisation is shorter in case of family firms than non-family firms. Implications & Recommendations: Strategic thinking seems to be very important while going international. A well thought-out strategy can stimulate the whole process of internationalisation, so decision makers, especially entrepreneurs, should pay more attention to strategic aspects, even in early stages of development or early internationalisation. Contribution & Value Added: The article attempts to enrich the ongoing scientific discourse on the role of time and the pace of internationalisation by adding some evidence from Poland illustrating and verifying the links between strategic thinking as well as familiness of firms and the speed of internationalisation measured in years from the establishment of firms.

    Puumala virus (PUUV) represents one of the most important hantaviruses in Central Europe. Phylogenetic analyses of PUUV strains indicate a strong genetic structuring of this hantavirus. Recently, PUUV sequences were identified in the natural reservoir, the bank vole (Myodes glareolus), collected in the northern part of Poland. The objective of this study was to evaluate the presence of PUUV in bank voles from southern Poland. A total of 72 bank voles were trapped in 2009 at six sites in this part of Poland. RT-PCR and IgG-ELISA analyses detected three PUUV positive voles at one trapping site. The PUUV-infected animals were identified by cytochrome b gene analysis to belong to the Carpathian and Eastern evolutionary lineages of bank vole. The novel PUUV S, M and L segment nucleotide sequences showed the closest similarity to sequences of the Russian PUUV lineage from Latvia, but were highly divergent to those previously found in northern Poland, Slovakia and Austria. In conclusion, the detection of a highly divergent PUUV lineage in southern Poland indicates the necessity of further bank vole monitoring in this region allowing rational public health measures to prevent human infections.

  13. Poland: A Dark Side of Church Cultural Policy

    Directory of Open Access Journals (Sweden)

    Szocik Konrad

    2015-12-01

    Full Text Available The cultural policy of the Roman Catholic Church in Poland is incorporated into state-run cultural policies. The organs of public authority enforce the objectives of Church regardless of Church’s actual ability to influence the society. It should be pointed out that the secularization of religion in Poland is frequently misinterpreted and usually equated with its deprivatization. It is worth mentioning that Catholicism is the dominant religion of the country and the Roman Catholic Church has hold a special position in Poland and play a major role in the country’s social and political life. In practice, however, Polish society appears to be religiously indifferent. This paper proves that the official, state-run cultural policy in Poland is based on favoritism of the Roman Catholic Church, regardless of Church’s actual ability to wield influence on society. Thus, there is a variety of implicit and explicit cultural policies implemented by the authorities to support Church. This work also aims at addressing the question of social attitudes to women, especially the one concerning the UN and EU law embracing women’s rights, until recently still not implemented in Poland. This paper further explores some peculiarities of this topic as an example of a specific outcome of Church cultural policy and its impact on both the past and present-day society.

    TBM3 is an open source package for computational simulations of quantum materials at multiple scales in length and time. The project originated to investigate the multiferroic behavior in transition-metal oxide heterostructures. The framework has also been designed to study emergent phemona in other quantum materials like 2-dimensional transition-metal dichalcogenides, graphene, topological insulators, and skyrmion in materials, etc. In the long term, we will enable the package for transport and time-resolved phenomena. TBM3 is currently a C++ based numerical tool package and framework for the design and construction of any kind of lattice structures with multi-orbital and spin degrees of freedom. The fortran based portion of the package will be added in the near future. The design of TBM3 is in a highly flexible and reusable framework and the tight-binding parameters can be modeled or informed by DFT calculations. It is currently GPU enabled and feature of CPU enabled MPI will be added in the future.

    Recovery of various signal transduction molecules in the detergent-resistant membrane microdomain (DRM) fraction suggests the importance of this region in cellular functions. Insolubility of the outer leaflet of DRM to the non-ionic detergent is ascribed to the tight association of cholesterol and sphingolipid. Since, poor localization of sphingolipid is observed in the inner leaflet, the physicochemical background of the insolubility of the inner leaflet is hence still an enigma. NAP-22 (also called BASP1 or CAP-23) is a neuron-enriched calmodulin-binding protein and one of the major proteins in the DRM of the neuronal cell membrane. A previous study showed the presence of several lipids in a NAP-22 fraction after the process of extraction and column chromatography. In this study, the effect of lipid extraction on NAP-22 was studied through native-gel electrophoresis, ultracentrifugation, and electron microscopic observation. The mobility of NAP-22 in native-PAGE was shifted from low to high after delipidation. Delipidated NAP-22 bound phosphatidylserine (PS), phosphatidylinosotol, and ganglioside. Some part of the mixture of PS and NAP-22 was recovered in the insoluble fraction after Triton X-100 treatment and the addition of cholesterol enhanced the amount of NAP-22 in the insoluble fraction.

    1986-01-01

    Two types of tank systems are present at the Livermore Site: tanks and associated piping for the storage of fuel (forty-three systems), and tanks or sumps and associated piping for the retention of potentially contaminated wastewater (forty systems). The fuel systems were tested using commercially available test methods: Petro-Tite, Hunter Leak Lokator, Ezy-Chek, and Associated Environmental Systems (A.E.S.). In contrast to fuel tank systems, wastewater systems have containers that are predominantly open at the top and not readily testable. Therefore, a project to test and evaluate all available testing methods was initiated and completed. The commercial method Tank Auditor was determined to be appropriate for testing open-top tanks and sumps and this was the method used to test the majority of the open-top containers. Of the 81 tanks tested, 61 were found to be leak tight, 9 were shown to have leaks, and 11 yielded inconclusive results. Two tanks have not yet been tested because of operational constraints; they are sheduled to be tested within the next two months. Schedules are being developed for the retesting of tanks and for remedial actions

    Tight junctions (TJs) are essential for normal function of epithelia, restricting paracellular diffusion and contributing to the maintainance of cell surface polarity. Superficial cells of the urothelium develop TJs, the basis for the paracellular permeability barrier of the bladder against diffusion of urinary solutes. Focusing on the superficial cell layer of stratified cell cultures of an immortalized human ureteral cell line, TEU-2 cells, we have examined the presence of TJ and TJ-associated proteins. TEU-2 cells were treated with calcium chloride and fetal bovine serum culture conditions used to induce stratification that resembles the normal transitional epithelial phenotype. Cultures were examined for TJ and TJ-associated proteins by confocal immuno-fluorescence microscopy and evaluated for TJ mRNA by reverse transcriptase-polymerase chain reaction (RT- PCR). TEU-2 cultures exhibited immunoreactivity at intercellular margins for claudins 1, 4, 5, 7, 14 and 16 whereas claudins 2, 8 and 12 were intracellular. RT-PCR corroborated the presence of these claudins at the mRNA level. The TJ-associated proteins occludin, JAM-1, and zonula occludens (ZO-1, ZO-2 and ZO-3) were localized at cell margins. We have found that numerous TJs and TJ-associated proteins are expressed in stratified TEU-2 cultures. Further, we propose TEU-2s provide a useful ureteral model for future studies on the involvement of TJs proteins in the normal and pathological physiology of the human urinary system. PMID:18553212

    In 2010 and 2011 the collimation system has been operated with relaxed settings, i.e. with retractions between different collimator families larger than the nominal settings that provide optimum cleaning. This configuration ensured a sufficient cleaning performance at 3.5 TeV while allowing larger tolerances on orbit control. Tighter collimator settings were proposed to push the cleaning performance and to allow larger orbit margins between TCDQ dump protection and tertiary collimators, which opens the possibility to push further the LHC β* reach. After having verified with beam that the cleaning is improved as expected, the feasibility of tighter collimator settings must be addressed with high stored intensity. For this purpose, an end-of-fill study was proposed after a standard physics fill with 1380 bunches nominal bunches at 3.5 TeV, for a total stored energy of 95 MJ. During this test, primary and secondary collimators were moved to that tight settings after about 8 hours of stable physics conditions in...

    The main index for integrity of the fuel rods cladding is the specific activity value of the primary coolant. This value determines the safe operation of the reactor. The limit for safe operation of WWER-1000 reactor is the value of the total activity of Iodine isotopes in the primary coolant 5.0x10 -3 Ci/l. The paper briefly describes the methodology for performing a fuel tightness test (sipping test) and shows the results from these tests performed during the period 1987 -1999 in units 5 and 6 at the Kozloduy NPP. An additional index related to the safe operation is defined to characterize the fuel cladding integrity Fuel Reliability Index (FRI). The FRI is defined as value of the average activity of 131 I in the primary coolant, corrected with a part of precipitated 235 U migration and fixed to the general permanent purification frequency. Two criteria (quantitative and statistic) are determined to qualify the fuel cladding integrity. The results from sipping tests show good reliability of the fuel irradiated in unit 5 and 6 at the Kozloduy NPP

    Landauer-Buttiker formalism with the assumption of semi-infinite electrodes as reservoirs has been the standard approach in modeling steady electron transport through nanoscale devices. However, modeling dynamic electron transport properties, especially nanoscale capacitance, is a challenging problem because of dynamic contributions from electrodes, which is neglectable in modeling macroscopic capacitance and mesoscopic conductance. We implement a self-consistent quantum tight-binding model to calculate capacitance of a nano-gap system consisting of an electrode capacitance C‧ and an effective capacitance Cd of the middle device. From the calculations on a nano-gap made of carbon nanotube with a buckyball therein, we show that when the electrode length increases, the electrode capacitance C‧ moves up while the effective capacitance Cd converges to a value which is much smaller than the electrode capacitance C‧. Our results reveal the importance of electrodes in modeling nanoscale ac circuits, and indicate that the concepts of semi-infinite electrodes and reservoirs well-accepted in the steady electron transport theory may be not applicable in modeling dynamic transport properties.

    Object: In a construction for air-tightly connecting radioactive material handling equipment with a radioactive waste container through a vinyl bag, to use a multi-stage expansion tube to introduce the radioactive waste into the waste container in safe and positive manner. Structure: During normal operation in the radioactive material handling equipment, a multi-stage expansion cylinder is extended by operation of a remote shaft to suitably throw the waste in a state with a vinyl bag protected, whereas when the waste is disposed away from the equipment, the multi-stage expansion cylinder is contracted and received into a holder, and the vinyl bag is heated and sealed at a given position and cut, after which a cover of an outer container for disposal is closed and carried out. The vinyl bag remained on the side of the holder after sealed and cut is put into the waste container after a fresh vinyl bag, in which another waste container is received, has been secured to the holder.

    There are evidences that the fluid flow in tight and shale formations does not follow Darcy law, which is identified as pre-Darcy flow. Here, the unsteady linear flow of a slightly compressible fluid under the action of pre-Darcy flow is modeled and a generalized Boltzmann transformation technique is used to solve the corresponding highly nonlinear diffusivity equation analytically. The effect of pre-Darcy flow on the pressure diffusion in a homogenous formation is studied in terms of the nonlinear exponent, m, and the threshold pressure gradient, G1. In addition, the pressure gradient, flux, and cumulative production per unit area for different m and G1 are compared with the classical solution of the diffusivity equation based on Darcy flow.

  3. Claudin-21 Has a Paracellular Channel Role at Tight Junctions

    KAUST Repository

    Tanaka, Hiroo

    2016-01-05

    Claudin protein family members, of which there are at least 27 in humans and mice, polymerize to form tight junctions (TJs) between epithelial cells, in a tissue- and developmental stage-specific manner. Claudins have a paracellular barrier function. In addition, certain claudins function as paracellular channels for small ions and/or solutes by forming selective pores at the TJs, although the specific claudins involved and their functional mechanisms are still in question. Here we show for the first time that claudin-21, which is more highly expressed in the embryonic than the postnatal stages, acts as a paracellular channel for small cations, such as Na+, similar to the typical channel-type claudins claudin-2 and -15. Claudin-21 also allows the paracellular passage of larger solutes. Our findings suggest that claudin-21-based TJs allow the passage of small and larger solutes by both paracellular channel-based and some additional mechanisms. © 2016, American Society for Microbiology.

    The fact that, since 1 May 2004, Poland has the status of European Union member involves certain consequences for Poland's competitiveness in the international services trade market. What competitive position will Poland finally occupy among the EU countries in the postaccession period will to a large extent depend on Poland's present position in the services trade with the EU countries. So, the paper tries to present, on the basis of the most recent available statistical data published by th...

  5. Dew chemistry near a motorway in SW Poland

    2010-07-01

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

    Epidemiologic data on multiple sclerosis (MS) in Poland are limited. Our objectives were to assess a mean annual incidence rate, and MS prevalence on December 31, 2015 in the Swietokrzyskie province (central Poland). We analyzed data of 1525 patients, collected in the Polish Multiple Sclerosis Registry. On December 31, 2015, overall crude prevalence of MS was not less than 121.3/100,000 (95% CI, 114.6-128.4). Significantly higher prevalence was recorded in females (167.1; 95% CI, 155.6-179.1) than in males (73.2; 95% CI, 64.2-82.6; PPoland confirmed that central Poland is a high risk area for MS.

    The surface warming has been widespread over the entire globe. Central Europe, including Poland, is not an exception. Global temperature increases are accompanied by changes in other climatic variables. Climate change in Poland manifests itself also as change in annual sums of precipitation. They have been slightly growing but, what is more important, seasonal and monthly distributions of precipitation have been also changing. The most visible increases have been observed during colder half-year, especially in March. A decreasing contribution of summer precipitation total (June-August) to the annual total is observed. Climate projections for Poland predict further warming and continuation of already observed changes in the quantity of precipitation as well as its spatial and seasonal distribution.

  10. 'Other' Posts in 'Other' Places: Poland through a Postcolonial Lens?

    Mayblin, Lucy; Piekut, Aneta; Valentine, Gill

    2016-02-01

    Postcolonial theory has tended to focus on those spaces where European colonialism has had a territorial and political history. This is unsurprising, as much of the world is in this sense 'postcolonial'. But not all of it. This article focuses on Poland, often theorised as peripheral to 'old Europe', and explores the application of postcolonial analyses to this 'other' place. The article draws upon reflections arising from a study of responses to ethnic diversity in Warsaw, Poland. In doing so we conclude that postcolonialism does indeed offer some important insights into understanding Polish attitudes to other nationalities, and yet more work also needs to be done to make the theoretical bridge. In the case of Poland we propose the 'triple relation' be the starting point for such work.

  11. Controlling the production and distribution of drugs in communist Poland.

    2014-01-01

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

    The paper presents results on determination of 90 Sr in bilberry and cowberry leaves (Vaccinium myrtillus and Vaccinium vitis-idaea) and the use of these plants as bio-monitors of radiostrontium contamination in Poland. Radiostrontium was determined by mean of liquid scintillation spectrometry preceded by radiochemical separation using Sr-resin and 85 Sr tracer. The approximate map of 90 Sr contamination of Poland is presented. The activity ratio between 90 Sr and obtained earlier data for 137 Cs in the same samples is discussed. The enhancement of radiostrontium content observed in northeastern Poland seems to be the trace of hot-particles fallout from initial Chernobyl cloud, which passed over Polish territory toward Scandinavia.

    2014-09-01

    Full Text Available Basidiomata of Callistosporium pinicola were collected in years 2012–2013, on strongly decayed fallen trunks of Picea abies and Abies alba on two remote sites, localized in North-eastern and southern Poland. These localities represent the first records of this fungus in Poland. A full description and illustration of C. pinicola based on Polish specimens are provided and the distinguishing features and delimitation of the species are briefly discussed. The ecology of C. pinicola, its general distribution and threat are also presented. As all specimens of C. pinicola were collected only in recent years we suggest that this species is increasing its distribution in Poland. However, we cannot rule out the possibility that, because of its cryptic nature, C. pinicola has been much overlooked in the past.

    1993-01-01

    Today, there are two steps of human rabies impendence: a. exposures to rabid or rabies suspected animals b. human deaths due to rabies. Red foxes, dangerous rabies reservoir are responsible for the main tendency and spread of rabies in Poland (over 2000 cases in 1992). This has a direct bearing on the treatment of exposed persons and on rabies among unvaccinated domestic animals. The number of persons requesting post exposure rabies treatment is also increasing--6500 vaccinees in 1992. During last eight years no case of human death was registered in Poland. Mass parenteral canine vaccination campaign and effective control methods of rabies in dogs in Poland are the mostly successful and significant elements separating wild animal rabies from human society. Any inaccuracy on this field would be the risk of transmission of wild rabies to human surrounding.

    2016-09-01

    Full Text Available The paper includes analysis and assessment of trade in the ICT services performance of Poland. This study is looked at the trade position, essentially on the basis of the share in the world ICT services exports, revealed comparative advantage (RCA, and trade coverage ratio. It also identifies trends of the world trade in the ICT services. The statistics are derived from the basis of UNCTAD and Eurostat. International trade in the ICT ser-vices sector has specific characteristics and the interpretation of results of this trade is to take account of the particular nature of the ICT services. Poland is currently not revealed comparative advantage in the ICT services exports, but has had positive balance. Practically all trade indicators for Poland show very strong growth, which indicate a significant improvement in its ICT services trade position.

  19. Pedestrian Safety in Road Traffic in Poland

    2017-10-01

    Every third road accident in Poland involves a pedestrian as a participant or, most of the time, a casualty. Pedestrian accidents are usually the result of complex situations and the outcome of a number of factors related to driver and pedestrian behaviour and road infrastructure. Safety depends largely on how well the traffic condition is perceived and on visibility in traffic. The paper presents the results of analyses of methodologies for systematic studies of pedestrian behaviour and pedestrian-driver relations. The effects of the location of the site, type of cross-section and other selected parameters on pedestrian and driver behaviour are demonstrated. The analyses showed that pedestrians are most often put at risk by too long pedestrian crossings, vehicles going too fast around pedestrian crossings, lack of proper sight distance and poorly lit or unlit pedestrian crossings. The reason for such defective infrastructure is that planners, designers, contractors and maintenance services are not receiving any support from design, marking and maintenance regulations for pedestrian traffic. In addition, the Road Traffic Law is not restrictive enough when it comes to drivers’ obligations towards pedestrian safety. Polish design regulations allow long pedestrian crossings up to four lanes in one direction or three lanes in two directions irrespective of traffic control and speed limits. Pedestrian crossings should be kept at a maximum of three lanes. There is nothing in the design regulations about the required driver-pedestrian sight distance. Neither does the Road Traffic Law help engineers with that. It is legal to park vehicles within 10 m of a pedestrian crossing which does not guarantee the necessary sight distance. Drivers must be able to see a pedestrian waiting or stepping onto the crossing from a distance that will help them come to a stop safely. It is safer to follow the principle of providing adequate pedestrian sight distance. Recommendations for

    Oncoplastic and reconstructive techniques are essential tools in the armamentarium of contemporary breast surgeons. The aim of the study was to identify oncoplastic reconstructive patterns in breast cancer centers across Poland. A questionnaire of 18 questions was sent by email to the members of the Polish Society of Surgical Oncology and the Polish Society of Plastic, Reconstructive and Esthetic Surgery via their dedicated websites. The numbers of breast cancer patients operated on in each center ranged from 120 to 904 per year. Breast-conserving surgery (BCS) predominated in all but one center (range 50-70%). Immediate breast reconstructions (IBR) accounted for 6-42% of procedures, The most frequent type of IBR was either a two-stage expander followed by a permanent implant or one-stage implant- based with or without synthetic mesh. The most frequent type of delayed breast reconstruction (DBR) was a two-stage expander followed by implant-based reconstruction. None of the surveyed cancer centers performed free flap reconstruction. Deep inferior epigastric perforator (DIEP) flaps were performed in the plastic surgery department. Reconstructions based on pedicled flaps were performed in cancer centers. Acellular dermal matrices (ADM) and fat transfer were used in selected centers. In the clinical scenario of adjuvant radiotherapy, delayed breast reconstruction was favored. The full range of oncoplastic BCS was performed. Patient-reported outcome measures (PROM) and complications were assessed. Our findings can act as a platform for further improvement in skills, certification, data collection and audit, including patient reported expectation measures. There is also an urgent need to address pan-European inconsistencies in procedural reimbursement.

  1. Abortion, church and politics in Poland.

    1992-01-01

    In early 1991 the abortion debate in Poland entered its new stage. The prolife and prochoice options had already clashed in the early 1930s over a new penal code and backstreet abortions. According to the code of 1932, induced abortion was allowed in cases of rape, incest, or for medical indications. Abortion was legalized in 1956, but subsequently it came under attack from Catholic circles, and by 1989 the Unborn Child Protection Bill was drafted which criminalized abortion. Only 11% of Polish women use modern contraceptives. The less efficient methods are the most prevalent: the natural method (Ogino-Knaus calendar), 35% of couples; coitus interruptus, 34%; condoms, 15%; oral contraceptives 7%; chemical spermicides, 2.5%; and the IUD 2%. According to size of Catholic Church estimate there are 600,000 abortions yearly. In contrast, official statistics indicate that the number of abortions is decreasing: 137,950 in 1980; 105,300 in 1988; 80,100 in 1989; 59,400 in 1990. In January 1991 the Constitutional Tribunal dismissed the motion of the Polish Feminist Association against the restrictive regulations of the Ministry of Health concerning abortion. After a parliamentary stalemate on the Unborn Child Protection Bill a commission consisting of 46 persona (1.2 of them women, 20 persons from the prochoice and 24 from the prolife lobby) continued the debate on the bill. Public opinion polls conducted by independent groups in November 1990 showed that about 60% of citizens were against the Senate's draft. Since then interest in the abortion issue has dwindled, and only 200 women and men took part in a prochoice demonstration in front of the parliament on January 25, 1991. In the spring of 1989 and in September 1990 thousands had participated in similar demonstrations. The prevailing attitude is that if the antiabortion bill is passed nothing can be done.

    Full Text Available Background . Home care (HC is placed between the health and social welfare systems, and the clients of HC mostly need health services. Along with other providers, family doctors (FDs are usually involved in the provision of care. Objectives. This paper aims to describe and compare the involvement of HC providers to elderly and disabled persons in Poland and Estonia. Material and methods . This study is part of the international project EURHOMA P (Mapping Professional Home Care in Europe. Data was collected in 2008–2010. Experts from different areas of health and social care were queried by using a questionnaire containing structured case narratives, which were hypothetical descriptions of the situations of elderly or disabled persons living at home and in need of care. Results. There are a number of HC services, e.g. nursing, medical and social, available in both countries. The application for HC is mostly made by the patient or a close family member; the point of entry to HC can differ and depends on the client’s primary problem. FDs, together with social workers, play an important role in the provision of HC services in both countries. However, due to a shortage of round-the-clock professional services at a client’s home, families are also expected to play a large role in providing HC . Conclusions . Health care professionals, mainly those working in primary health care, play a remarkable role in access to and provision of HC services. Nevertheless, responsibility for 24-hour care lies, to a large extent, with the client’s immediate family. This situation seems to be typical in Eastern European countries.

    The characteristics of extreme precipitation, including the dominant trends, were analysed for eight stations located in different parts of Poland for the period 1951-2010. Five indices enabling the assessment of the intensity and frequency of both extremely dry and wet conditions were applied. The indices included the number of days with precipitation ≥10mm·d-1 (R10), maximum number of consecutive dry days (CDD), maximum 5-day precipitation total (R5d), simple daily intensity index (SDII), and the fraction of annual total precipitation due to events exceeding the 95th percentile calculated for the period 1961-1990. Annual trends were calculated using standard linear regression method, while the fit of the model was assessed with the F-test at the 95% confidence level. The analysed changes in extreme precipitation showed mixed patterns. A significant positive trend in the number of days with precipitation ≥10mm·d-1 (R10) was observed in central Poland, while a significant negative one, in south-eastern Poland. Based on the analysis of maximum 5-day precipitation totals (R5d), statistically significant positive trends in north-western, western and eastern parts of the country were detected, while the negative trends were found in the central and northeastern parts. Daily precipitation, expressed as single daily intensity index (SDII), increased over time in northern and central Poland. In southern Poland, the variation of SDII index showed non-significant negative tendencies. Finally, the fraction of annual total precipitation due to the events exceeding the 1961-1990 95th percentile increased at one station only, namely, in Warsaw. The indicator which refers to dry conditions, i.e. maximum number of consecutive dry days (CDD) displayed negative trends throughout the surveyed area, with the exception of Szczecin that is a representative of north-western Poland.

    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.

  7. Urothelial Tight Junction Barrier Dysfunction Sensitizes Bladder Afferents

    2017-01-01

    Abstract Interstitial cystitis/bladder pain syndrome (IC/BPS) is a chronic voiding disorder that presents with pain in the urinary bladder and surrounding pelvic region. A growing body of evidence suggests that an increase in the permeability of the urothelium, the epithelial barrier that lines the interior of the bladder, contributes to the symptoms of IC/BPS. To examine the consequence of increased urothelial permeability on pelvic pain and afferent excitability, we overexpressed in the urothelium claudin 2 (Cldn2), a tight junction (TJ)-associated protein whose message is significantly upregulated in biopsies of IC/BPS patients. Consistent with the presence of bladder-derived pain, rats overexpressing Cldn2 showed hypersensitivity to von Frey filaments applied to the pelvic region. Overexpression of Cldn2 increased the expression of c-Fos and promoted the activation of ERK1/2 in spinal cord segments receiving bladder input, which we conceive is the result of noxious stimulation of afferent pathways. To determine whether the mechanical allodynia observed in rats with reduced urothelial barrier function results from altered afferent activity, we examined the firing of acutely isolated bladder sensory neurons. In patch-clamp recordings, about 30% of the bladder sensory neurons from rats transduced with Cldn2, but not controls transduced with GFP, displayed spontaneous activity. Furthermore, bladder sensory neurons with tetrodotoxin-sensitive (TTX-S) action potentials from rats transduced with Cldn2 showed hyperexcitability in response to suprathreshold electrical stimulation. These findings suggest that as a result of a leaky urothelium, the diffusion of urinary solutes through the urothelial barrier sensitizes bladders afferents, promoting voiding at low filling volumes and pain.

    1997-11-19

    This DOE-funded research into seismic detection of natural fractures is one of six projects within the DOE`s Detection and Analysis of Naturally Fractured Gas Reservoirs Program, a multidisciplinary research initiative to develop technology for prediction, detection, and mapping of naturally fractured gas reservoirs. The demonstration of successful seismic techniques to locate subsurface zones of high fracture density and to guide drilling orientation for enhanced fracture permeability will enable better returns on investments in the development of the vast gas reserves held in tight formations beneath the Rocky Mountains. The seismic techniques used in this project were designed to capture the azimuthal anisotropy within the seismic response. This seismic anisotropy is the result of the symmetry in the rock fabric created by aligned fractures and/or unequal horizontal stresses. These results may be compared and related to other lines of evidence to provide cross-validation. The authors undertook investigations along the following lines: Characterization of the seismic anisotropy in three-dimensional, P-wave seismic data; Characterization of the seismic anisotropy in a nine-component (P- and S-sources, three-component receivers) vertical seismic profile; Characterization of the seismic anisotropy in three-dimensional, P-to-S converted wave seismic data (P-wave source, three-component receivers); and Description of geological and reservoir-engineering data that corroborate the anisotropy: natural fractures observed at the target level and at the surface, estimation of the maximum horizontal stress in situ, and examination of the flow characteristics of the reservoir.

  9. Tight junctions: a barrier to the initiation and progression of breast cancer?

    LENUS (Irish Health Repository)

    Brennan, Kieran

    2010-01-01

    Breast cancer is a complex and heterogeneous disease that arises from epithelial cells lining the breast ducts and lobules. Correct adhesion between adjacent epithelial cells is important in determining the normal structure and function of epithelial tissues, and there is accumulating evidence that dysregulated cell-cell adhesion is associated with many cancers. This review will focus on one cell-cell adhesion complex, the tight junction (TJ), and summarize recent evidence that TJs may participate in breast cancer development or progression. We will first outline the protein composition of TJs and discuss the functions of the TJ complex. Secondly we will examine how alterations in these functions might facilitate breast cancer initiation or progression; by focussing on the regulatory influence of TJs on cell polarity, cell fate and cell migration. Finally we will outline how pharmacological targeting of TJ proteins may be useful in limiting breast cancer progression. Overall we hope to illustrate that the relationship between TJ alterations and breast cancer is a complex one; but that this area offers promise in uncovering fundamental mechanisms linked to breast cancer progression.

    2017-12-01

    The paper presents the problem of excessive air pollution in Poland caused mainly by low emission. The emission arises in result of heating flats by means of old and energetically inefficient heating installations. In Poland and Bulgaria the inhaled air is of the worst quality out of all EU countries. The paper presents economic and technical problems related to low emission occurring during the combustion of solid fuels in local boiler houses. Furthermore, the most significant economic issues, connected with the reduction of low emission are discussed, as well as technological possibilities of efficient reduction of the amount of pollution in the atmosphere. Conclusions are presented at the end of the article.

In view of Poland’s tragic history and the economic liberalisation that has taken place since 1989, we believe that the EU should adopt a generous approach toward its application. Unfortunately it looks as if the EU wants Poland to conform with all its laws before it can join. Our research suggests that the EU should pursue an open trade, labour and investment policy.

  16. A theoretical investigation of tight-binding thermolysin inhibitors.

    1997-08-29

    A tight-binding thermolysin inhibitor, Cbz-Phe-psi[PO2NH]-Leu-Ala (ZFpLA, Ki = 0.068 nM), and its analogs, ZRp(O)LA (R = Ala, Leu or Phe) have been studied using the finite difference solution to the linearized Poisson-Boltzmann equation (FDPB) and solvation entropy correction (SEC). The binding energy difference between conformationally different thermolysin inhibitors ZFpLA and ZGpLL is estimated using three approaches. Two of approaches use the X-ray structures of ZFpLA-thermolysin and ZGpLL-thermolysin structures. The third one uses both X-ray structures to calculate binding energy differences from ZFpLA and ZGpLL to a hypothetical intermediate MepLA. All the results are qualitatively correct with one closely reproducing the experimental value. The enhancement of the ZFpLA binding is attributed largely to the solvation entropy or "hydrophobic force". The binding mode of the ZGpLR N-terminal moiety appears to be electrostatically unfavorable. Reducing the polarity of that moiety is predicted to enhance binding affinity. The binding trends due to the hydrophobic variation of ZRp(O)LA are calculated within 1 kcal/mol of the experimental values. Increasing lipophilicity of a ligand favors the binding due to the difference of surface area change between the free state and the bound state. The analysis of energetic components shows that these trends are not specific for the binding of phosphorus-containing inhibitors but are generally true for protein-ligand interactions. The electrostatic calculation does not support the involvement of the second protonation of ZFpLA in binding. Therefore, reexamining the second protonation of ZFpLA or seeking further experimental support seems appropriate. The structural sensitivity of the FDPB calculation was assessed by using ligand and receptor structures from different X-ray studies of thermolysin. The small deviations (< 0.3 A) in the receptor structures do not cause significant changes in electrostatic binding energy if there

  17. Road Infrastructure Safety Management in Poland

    2017-10-01

    The objective of road safety infrastructure management is to ensure that when roads are planned, designed, built and used road risks can be identified, assessed and mitigated. Road transport safety is significantly less developed than that of rail, water and air transport. The average individual risk of being a fatality in relation to the distance covered is thirty times higher in road transport that in the other modes. This is mainly because the different modes have a different approach to safety management and to the use of risk management methods and tools. In recent years Poland has had one of the European Union’s highest road death numbers. In 2016 there were 3026 fatalities on Polish roads with 40,766 injuries. Protecting road users from the risk of injury and death should be given top priority. While Poland’s national and regional road safety programmes address this problem and are instrumental in systematically reducing the number of casualties, the effects are far from the expectations. Modern approaches to safety focus on three integrated elements: infrastructure measures, safety management and safety culture. Due to its complexity, the process of road safety management requires modern tools to help with identifying road user risks, assess and evaluate the safety of road infrastructure and select effective measures to improve road safety. One possible tool for tackling this problem is the risk-based method for road infrastructure safety management. European Union Directive 2008/96/EC regulates and proposes a list of tools for managing road infrastructure safety. Road safety tools look at two criteria: the life cycle of a road structure and the process of risk management. Risk can be minimized through the application of the proposed interventions during design process as reasonable. The proposed methods of risk management bring together two stages: risk assessment and risk response occurring within the analyzed road structure (road network, road

  13. Organic food consumption in Poland: Motives and barriers.

    Science.gov (United States)

    Bryła, Paweł

    2016-10-01

    This paper aims to investigate selected aspects of organic food consumption in Poland. We conducted a survey in a representative sample of 1000 consumers. Polish consumers are convinced that organic food is more expensive, healthier, more environmentally friendly, more tasty and more authentic than conventional food. They believe its arouses more trust, has a better quality, is subject to more strict controls, and is produced in a more traditional way. According to Polish consumers, the most important characteristics of organic food are healthiness and high quality. The perceived authenticity of organic food depends on its natural taste, product quality, labelling, in particular having a European quality sign, as well as the retailer type and a separate exposition place in the points of purchase (merchandising). The critical barrier to the development of the organic food market in Poland is the high price, followed by an insufficient consumer awareness, low availability of organic products, short expiry dates and low visibility in the shop. The principal motives of organic food selection in Poland include: healthiness, ecological character of the product, food safety considerations, superior taste, and quality assurance. We identified the motives for and barriers to organic food consumption in Poland. Copyright © 2016 Elsevier Ltd. All rights reserved.

In 2011, there were 453 radiation oncologists – specialists (1 in 168 patients), 325 medical physicists (1 in 215 patients), and 883 radiotherapy technicians (1 in 86 patients) vs. 320, 188, and 652, respectively, in 2005. The number of linear accelerators increased by 60%, from 70 units in 2005 to 112 in 2011. The current linac/patient ratio in Poland is 1 linac per 678 patients. Waiting times from diagnosis to the start of treatment has decreased. Conclusion Compared to 2005, there are more treatment facilities, more and better equipment (linacs), and more cancer care specialists. There are still large differences between the 16 Polish provinces in terms of equipment availability and ease of access to treatment. However, radiotherapy services in Poland have improved dramatically since the year 2005. PMID:24416548

    Both the Czech Republic and Poland as former Communist countries, are transforming their economies from central planning to a free market. This applies equally to energy planning and because they are starting from the same point, they have come up with very comparable solutions despite strong cultural differences, so that the parallels are striking. This study analyzes the energy management in local authorities in Poland and the Czech Republic with the objective of better: identifying the current situation, identifying the opportunities for action both now and in an extended European Union, identifying the constraints that may hinder full integration of East European municipalities in European Union programmes, improve the integration of municipalities in the countries concerned in pan-European networks of municipalities interested in energy issues. The study reviews the powers and responsibilities of local authorities in the energy field and the institutional framework within which local authorities work. There are now 16 directly elected regional authorities in Poland and the local authorities have been restructured into two levels, the Powiad and the Gmina. Similarly, in the Czech Republic 14 elected regional authorities have been established. This document brings together 2 reports: the final report and the study report about the energy policies in Poland and in the Czech republic: structure of local government, general and institutional aspects, national political organisation, national administrative organisation, municipal role in production and distribution, regulation and planning, energy issues, energy management policies, specific aspects at local level etc... The conclusions from two review seminars (Jablonec nad Nison (Czech republic), 25-26 January 2001, and Bielsko Biala (Poland), 22-23 February 2001) and some fact files on 4 large Czech towns and 4 large Polish towns complete the study.

    Continuous population aging has raised international policy interest in promoting active aging (AA). AA theoretical models have been defined from a biomedical or a psychosocial perspective. These models may be expanded including components suggested by lay individuals. This paper aims to study the correlates of AA in three European countries, namely, Spain, Poland, and Finland using four different definitions of AA. The EU COURAGE in Europe project was a cross-sectional general adult population survey conducted in a representative sample of the noninstitutionalized population of Finland, Poland, and Spain. Participants (10,800) lived in the community. This analysis focuses on individuals aged 50 years old and over (7,987). Four definitions (two biomedical, one psychosocial, and a complete definition including biomedical, psychosocial, and external variables) of AA were analyzed. Differences in AA were found for country, age, education, and occupation. Finland scored consistently the highest in AA followed by Spain and Poland. Younger age was associated with higher AA. Higher education and occupation was associated with AA. Being married or cohabiting was associated with better AA compared to being widowed or separated in most definitions. Gender and urbanicity were not associated with AA, with few exceptions. Men scored higher in AA only in Spain, whereas there was no gender association in the other two countries. Being widowed was only associated with lower AA in Poland and not being married was associated with lower AA in Poland and Finland but not Spain. Associations with education, marital status, and occupation suggest that these factors are the most important components of AA. These association patterns, however, seem to vary across the three countries. Actions to promote AA in these countries may be addressed at reducing inequalities in occupation and education or directly tackling the components of AA lacking in each country.

  8. High energy physics in Poland: the first 50 years

    International Nuclear Information System (INIS)

    Wroblewski, A.K.

    1993-01-01

    High energy physics in Poland started in 1933 when Stanislaw Ziemecki and Konstanty Narkiewicz-Jodko performed measurements of the latitude effect for cosmic rays. Subsequently, experiments with cosmic rays were carried out in balloon flights in a deep salt mine. Other Polish pioneers in this field were Ignacy Adamczewski, Czeslaw Bialobrzeski, Marian Miesowicz, Szczepan Szczeniowski and Jan Wesolowski. The ambitious 'Star of Poland' project of a stratospheric balloon flight to study cosmic rays up to an altitude of 30000 meters was not successful, first because of the fire accident and then of the outbreak of World War II. The destruction of laboratories during the war has slowed down the development of high energy physics in Poland by at least twelve years. However, in the late forties Marian Miesowicz started important cosmic ray studies in Cracow. In 1952 research using nuclear emulsions was initiated in Warsaw by Marian Danysz and Jerzy Pniewski. Two years later Marian Miesowicz and Jerzy Gierula began similar research in Cracow. In the late fifties Aleksander Zawadzki in Lodz started comprehensive studies of extensive air showers. Already in 1963 the number of experimental and theoretical papers on high energy physics published in Poland exceeded 100. Strong experimental and theoretical groups have been established in Cracow, Lodz and Warsaw. To supplement research with emulsions and bubble chambers the construction of electronic detectors for on-line experiments has been instituted. Thus, in the early eighties Polish high energy physicists were ready to participate in large projects such as DELPHI at LEP and ZEUS and H1 at HERA. The discovery of hypernuclei by Danysz and Pniewski in 1952 may be regarded as the most important achievement of physics in post-war Poland. (author). 108 refs, 26 figs, 1 tab

    The success of shale/tight plays and the advanced exploitation technology applied in North America have triggered interest in exploring and exploiting tight oil in China. Due to the increased support of exploration and exploitation,great progress has been made in Erdos basin, Songliao basin, Junggar basin, Santanghu basin, Bohai Bay basin, Qaidam Basin, and Sichuan basin currently. China's first tight oil field has been found in Erdos basin in 2015, called xinanbian oil field, with over one hundred million tons oil reserves and one million tons of production scale. Several hundred million tons of tight oil reserve has been found in other basins, showing a great potential in China. Tight oil in China mainly developed in terrestrial sedimentary environment. According to the relations of source rock and reservoir, the source-reservoir combination of tight oil can be divided into three types, which are bottom generating and top storing tight oil,self- generating and self-storing tight oil,top generating and bottom storing tight oil. The self- generating and self-storing tight oil is the main type discovered at present. This type of tight oil has following characteristics:(1) The formation and distribution of tight oil are controlled by high quality source rocks. Terrestrial tight oil source rocks in China are mainly formed in the deep to half deep lacustrine facies. The lithology includes dark mudstone, shale, argillaceous limestone and dolomite. These source rocks with thickness between 20m-150m, kerogen type mostly I-II, and peak oil generation thermal maturity(Ro 0.6-1.4%), have great hydrocarbon generating potential. Most discovered tight oil is distributed in the area of TOC greater than 2 %.( 2) the reservoir with strong heterogeneity is very tight. In these low porosity and permeability reservoir,the resources distribution is controlled by the physical property. Tight sandstone, carbonate and hybrid sedimentary rocks are three main tight reservoir types in

    The fall in rates of tuberculosis (TB) in many countries has been accompanied by the concentration of cases in the social risk groups including homeless persons. Comparison of TB features in homeless persons and in non-homeless patients. TB cases reported to National TB Register in Poland in whom information about the social status was available (the data about the social status were collected obligatorily in the years 2004-2013 only) were analysed. The results of DSTs were obtained from laboratory records and were available for the cases reported since 2010. Treatment outcome after 12 months was analysed for the cases registered between 2004-2012. The significance (Si) of the differences in proportions was assessed with chi-square test. Phomeless persons (HP) and 72,989 other patients (OP) with TB were included. In the group of HP, there was a greater proportion of males in comparison with OP (90.5% vs. 66.3%) (Si). The mean age of HP was 49.8 years (SD±10.9); of OP-52.9 years (SD±17.5) (Si). 16.6% of HP and 10.4% of OP were previously treated for TB (Si). The previous treatment was adequate in 62.2% of HP and in 85.8% of OP (Si). Pulmonary TB was in 98.0%, extrapulmonary TB in 2.0% of HP and, respectively, in 92.5% and 7.5% of OP (Si). Pulmonary TB was confirmed by culture in 76.3% of HP and in 64.5% of OP (Si). Sputum smears were positive in 70.7% of HP and in 62.5% of OP (Si). Caseous pneumonia occurred in 2.7% of homeless subjects and in 1.1% of OP (Si); infiltrative TB in 95.5% of HP and in 97.5% of OP (Si). Resistance to isoniazid was observed in 2.9% of HP and in 3.1% of OP; to rifampicin in 0.0% of HP and in 0.2% of OP; to isoniazid and rifampicin in 0.4% of HP and in 0.8% of OP. These differences were not Si. Treatment success rate among HP was 44.1%; default rate 24.8%; 4.0% of HP died from tuberculosis; 3.2% died from other causes; 5.2% were transferred and their outcomes were unknown; 0.4% were still on treatment; 0.4% had treatment failure; in 17

    Full Text Available The paper discusses a simple looking but highly nonlinear regime-switching, self-excited threshold model for hourly electricity prices in continuous and discrete time. The regime structure of the model is linked to organizational features of the market. In continuous time, the model can include spikes without using jumps, by defining stochastic orbits. In passing from continuous time to discrete time, the stochastic orbits survive discretization and can be identified again as spikes. A calibration technique suitable for the discrete version of this model, which does not need deseasonalization or spike filtering, is developed, tested and applied to market data. The discussion of the properties of the model uses phase-space analysis, an approach uncommon in econometrics. (original abstract

    Full Text Available Abstract Background Zonula occludens, also known as the tight junction, is a specialized cell-cell interaction characterized by membrane "kisses" between epithelial cells. A cytoplasmic plaque of ~100 nm corresponding to a meshwork of densely packed proteins underlies the tight junction membrane domain. Due to its enormous size and difficulties in obtaining a biochemically pure fraction, the molecular composition of the tight junction remains largely unknown. Results A novel biochemical purification protocol has been developed to isolate tight junction protein complexes from cultured human epithelial cells. After identification of proteins by mass spectroscopy and fingerprint analysis, candidate proteins are scored and assessed individually. A simple algorithm has been devised to incorporate transmembrane domains and protein modification sites for scoring membrane proteins. Using this new scoring system, a total of 912 proteins have been identified. These 912 hits are analyzed using a bioinformatics approach to bin the hits in 4 categories: configuration, molecular function, cellular function, and specialized process. Prominent clusters of proteins related to the cytoskeleton, cell adhesion, and vesicular traffic have been identified. Weaker clusters of proteins associated with cell growth, cell migration, translation, and transcription are also found. However, the strongest clusters belong to synaptic proteins and signaling molecules. Localization studies of key components of synaptic transmission have confirmed the presence of both presynaptic and postsynaptic proteins at the tight junction domain. To correlate proteomics data with structure, the tight junction has been examined using electron microscopy. This has revealed many novel structures including end-on cytoskeletal attachments, vesicles fusing/budding at the tight junction membrane domain, secreted substances encased between the tight junction kisses, endocytosis of tight junction

    The consequences of tight monetary policy are analyzed in an optimizing currency-substitution model of a small, open economy that operates under an open capital account and a flexible exchange rate. There is a reasonably good fit between the dynamics generated by the model and the stylized facts in the tight-money episodes that occurred in Kenya in 1993 and Nigeria in 1989-91. The study's results shed light on two issues: why tight money has provoked stupendous increases in inflation and the ...

    In this thesis, we investigate the electronic and optical properties of pure as well as of substitutionally alloyed II-VI and III-V bulk semiconductors and corresponding semiconductor quantum dots by means of an empirical tight-binding (TB) model. In the case of the alloyed systems of the type A{sub x}B{sub 1-x}, where A and B are the pure compound semiconductor materials, we study the influence of the disorder by means of several extensions of the TB model with different levels of sophistication. Our methods range from rather simple mean-field approaches (virtual crystal approximation, VCA) over a dynamical mean-field approach (coherent potential approximation, CPA) up to calculations where substitutional disorder is incorporated on a finite ensemble of microscopically distinct configurations. In the first part of this thesis, we cover the necessary fundamentals in order to properly introduce the TB model of our choice, the effective bond-orbital model (EBOM). In this model, one s- and three p-orbitals per spin direction are localized on the sites of the underlying Bravais lattice. The matrix elements between these orbitals are treated as free parameters in order to reproduce the properties of one conduction and three valence bands per spin direction and can then be used in supercell calculations in order to model mixed bulk materials or pure as well as mixed quantum dots. Part II of this thesis deals with unalloyed systems. Here, we use the EBOM in combination with configuration interaction calculations for the investigation of the electronic and optical properties of truncated pyramidal GaN quantum dots embedded in AlN with an underlying zincblende structure. Furthermore, we develop a parametrization of the EBOM for materials with a wurtzite structure, which allows for a fit of one conduction and three valence bands per spin direction throughout the whole Brillouin zone of the hexagonal system. In Part III, we focus on the influence of alloying on the electronic

    Usher syndrome type I is an autosomal recessive disease characterized by profound congenital hearing impairment and vestibular dysfunction followed by the onset of progressive pigmentary retinopathy in childhood or early adolescence. A locus (USH1C) for one form of this disease was previously assigned to the short arm of chromosome 11 through linkage studies in the Acadian population of southwestern Louisiana. Linkage analyses of a set of microsatellite markers in 27 Acadian families provide evidence that USH1C lies between D11S861 and D11S928. Three markers (D11S419, D11S921, and D11S899) that lie between the flanking markers show no recombination with USH1C, and all 54 chromosomes with the abnormal allele at the disease locus have identical alleles for D11S419 and D11S921. This haplotype was found on only 10 of 50 chromosomes with the normal allele at the disease locus, suggesting a strong founder effect. Of the 54 chromosomes with the abnormal allele, 12 had a divergent allele at D11S899. These results suggest that USH1C is in the 2-3-cM interval between D11S861 and D11S899. 16 refs., 2 figs., 3 tabs.

    Toxocariasis is a worldwide distributed zoonotic disease. Soil contaminated with Toxocara eggs appears to be the main source of infection for humans. The aim of our study was to estimate the environmental contamination with Toxocara eggs in public areas in northeastern Poland followed by the assessment of seroprevalence of toxocariasis in the children's population inhabiting the areas. A total of 168 soil samples were collected in June and September from public areas, and 28 from patients' residences. They were all examined for Toxocara eggs using the centrifugal flotation technique. Two-step serological tests comprising enzyme-linked immunosorbent assay (ELISA) and Western blot (WB) were performed in 190 children aged 2-17 without any symptoms of toxocariasis. The positive samples accounted for 36 and 32 % in the urban area, 39 and 18 % in the suburbs, and 39 and 46 % in parks, for June and September, respectively. All the sites located near the patients' residences with confirmed persistent toxocariasis were found contaminated with Toxocara eggs. A significant drop in the mean number of eggs was noted in the suburbs after summer (0.64 vs 0.18, p contamination was documented in soil from urban sandboxes and parks. The overall seroprevalence in children tested for toxocariasis was 4.2 % as determined by ELISA and WB (3.0 % in preschool children and 7.7 % in school children). The current study revealed high contamination of public areas in northeastern Poland with Toxocara eggs as well as marked seroprevalence in asymptomatic children. There is an urgent need to introduce and promote preventive health measures to limit spread of toxocariasis.

    Recommendations for diphtheria immunization are to apply an effective primary immunization in infancy and to maintain immunity throughout life. Immunity against diphtheria depends primarily on antibody to the diphtheria toxin. This study evaluated the seroprevalence of IgG diphtheria antitoxin in sera of healthy children, adolescents and adults in Poland. A total of 1387 serum samples collected between 2010 and 2012 from individuals with ages ranging from 1 month to 85 years were investigated. Antibody concentrations were measured with an enzyme-linked immunosorbent assay (Anti-Diphtheria Toxoid ELISA IgG, Euroimmun, Germany). The results showed that among 1387 individuals examined, 547 (39.4%) had anti-diphtheria toxoid IgG antibody levels below 0.1 IU/ml (36.9% ≤ 18 years and 40.5% >18 years old, respectively). The 212 (50.8%) children and 542 (55.9%) adults showed only basic protection (0.1-1.0 IU/ml) and need immediate booster. High levels of anti-diphtheria toxoid IgG antibodies (>1.0 IU/ml) were found more often in children and adolescent (12.2%) than in adults (3.6%) and this was statistically significant (P 60 years old. Characteristically, in individuals > 40 years old high levels of anti-diphtheria toxoid IgG antibodies (>1.0 IU/ml) were not seen. There were no statistically significant differences in results in relation to gender. The present study showed inadequate immunity levels to diphtheria amongst the Polish population, especially in adults > 40 years old and children ≤ 2 years old. To prevent reemergence of diphtheria an information campaign reminding people about recommendations concerning diphtheria booster vaccination in adults should be conducted. Moreover, the immunogenicity of the DTP vaccine used in Poland should be verified.

    The frequent and high consumption of sugar products, particularly sucrose, is one of the causative factors of dental caries. Meta-analyses assessing the relationship between sugar intake and dental caries revealed that a restricted sugar intake to less than 10% of the daily energy intake results in substantial health benefits. Sugar consumption in Poland is 2-fold higher than recommended by the WHO. As change in dietary habits is slow, knowledge of whether a gradual reduction of sugar consumption influences beneficially the dental condition is important. Assessment of the relationship between caries experience and sugar consumption in 12-year-old children. The data obtained from the Statistical Agricultural Yearbooks of the Central Statistical Office in Poland regarding the average yearly sugar intake by a person in the years 1995-2013, and caries prevalence (frequency and DMFT) resulting from the national epidemiological studies of the 12-year-old children conducted by the Ministry of Health in those years were analyzed. The data was analyzed by linear regression. Regression function parameters and coefficients of determination were assessed for a possible link between sugar consumption and dental caries frequency and severity was expressed as DMFT value. The mean yearly sugar intake by a statistical Pole ranged from 43.6 kg (2002) to 35.3 kg (2006). Despite a slight trend to lower the sugar consumption, its mean intake in 1995 and 2013 was the same (41.9 kg). Caries frequency and DMFT decreased in 2012 compared to 1995 from 90.5% to 79.6% and from 4.3 to 3.53 kg in 2012, respectively. The increased sugar intake by 1 kg/year caused the increase of caries frequency by 1% and DMFT value by 0.2. Even a relatively low decrease in sugar consumption can exert some beneficial influence on the dental condition in adolescents, particularly upon the severity of caries.

    Full Text Available Campylobacter infection is one of the most common enteric human diseases world-wide but the mechanism of Campylobacter pathogenicity has not been exactly explained yet. One of the main reasons is genotypic, hence phenotypic diversity of the bacterial isolates. The aim of the present study was to perform a molecular characterization of randomly selected C. jejuni and C. coli strains isolated from poultry faeces and carcasses in Poland. Several virulence gene markers were identified by polymerase chain reaction (PCR. Furthermore, genetic typing has also been used by the macrorestriction profiling with pulsed-field gel electrophoresis (PFGE. The results of the present study showed that all analyzed isolates of C. jejuni (n = 24 and C. coli (n = 24 contained the flaA and cadF sequences. On the other hand, the virB11 gene was present only in 6 of 48 (12.5% of the analyzed isolates, whereas most of the strains contained the cdt genes. Other virulence gene iam linked to Campylobacter invasiveness was present in 34 of 48 (72.9% strains. The restriction analysis of the whole genome digested with SmaI produced three main clonal groups designed as I, II (with two subgroups IIa and IIb, and III obtained by the comparison of macrorestriction profiling patterns. The results showed a poor correlation between Campylobacter profiles generated by a clonal molecular technique and the presence of virulence markers. Therefore, PCR detection of Campylobacter virulence markers can be utilized as a simple and rapid tool to discriminate stains recovered from different sources, especially when used in conjunction with the PFGE profile analysis as a complex strategy. These kinds of analyses had not been previously carried out in Poland and these results may generate more knowledge regarding the genetic diversity and molecular relationship of Campylobacter.

    Full Text Available Objective: The aim of the article is to identify and verify the relationship between internationalization and innovativeness as well as innovative behaviour of high-tech businesses in Polish context. Research Design & Methods: A quantitative research design was employed. A survey was conducted on the sample of 263 firms operating in high-tech industries in Poland. To verify the assumed relationships statistical instruments were used, including descriptive statistics, Chi-Square test, the Kruskal-Wallis test and multivariate regression. Findings: The level of innovativeness of investigated hi-tech firms was relatively high. Results suggest that the innovativeness of a business contributes to the intensification of the internationalization process of firms operating in high-tech industries. The regression model confirms the dependence of internationalization on three innovative behaviours, such as the general evaluation of innovativeness of the firm, the pace of innovation diffusion and the number of implemented innovations. Implications & Recommendations: Polish high-tech businesses seem to be relatively well internationalized, especially in comparisons to general business population. Policy makers should continue to support innovativeness of Polish economy, but especia­lly these industries which are highly innovative. Contribution & Value Added: The research presented in the article seems to be one of the first in Poland investigating into internationalization and innovation in high-tech industries. The results are in line with the majority of empirical evidence worldwide. The preliminary link between innovation and internationalization among Polish high–tech businesses was confirmed.

    Tight junctions are intercellular junctions localized at the most apical end of the lateral plasma membrane. They consist of four kinds of transmembrane proteins (occludin, claudins, junctional adhesion molecules, and tricellulin) and huge numbers of scaffolding proteins and contribute to the paracellular barrier and fence function. The mutation and deletion of these proteins impair the functions of tight junctions and cause various human diseases. In this paper, we provide an overview of rec...

    Full Text Available In 2017 statistics showed that Chinese Foreign Direct Investments (FDI in Poland for 2016 amounted to a more than half of all Chinese FDI in Poland for the 2000–2016. Yet the overall amount of Chinese FDI remains modest in comparison with Western Europe or even with Hungary. Despite much proclaimed Sino-Polish rapprochement in 2015–2016 and high hopes for OBOR/BRI initiative in Poland, cooperation with China has not been a breakthrough for Poland in terms of economic results. There have not been ground-breaking Sino-Polish projects and Polish government’s desire to strengthen ties with China loosened in late 2016/early 2017 (though it may revive now.There are several reasons for that, from the perception of Poland as non-attractive for majority Chinese investments, via lack of overall Polish strategy of attracting these investors to discrepancies of economic interests between Poland and China.

  9. Selective release of the digital extensor hood to reduce intrinsic tightness in tetraplegia

    2011-01-01

    Patients with tetraplegia may have various degrees of spasticity in the hand ranging from a completely clenched fist to reduced control of grip at triggered spasticity. The objective of the present study was to evaluate the functional effect of the distal ulnar intrinsic release procedure to reduce intrinsic tightness. Seventeen patients with tetraplegia (37 fingers) and with prominent intrinsic tightness were operated on for distal intrinsic release with a modification of the procedure to include only the ulnar side of the proximal phalanx. All the patients had more pronounced tightness on the ulnar than on the radial side of the affected finger. Long fingers were consistently the most affected digits. The intrinsic tightness was released completely in all patients and the range of motion (ROM) was improved by 25%, and up to 45% in mild and severe cases, respectively. The good immediate effects of treatment as shown by increased ROM remained intact by 6 months postoperatively. These data suggest that the distal ulnar intrinsic release procedure is a simple and valuable way of reducing intrinsic tightness and improving hand function and grip for patients with intrinsic tightness. This procedure can be added to other procedures such as lengthening and transfer of tendons. PMID:21504278

    2013-01-01

    A popular approach for medical image reconstruction has been through the sparsity regularization, assuming the targeted image can be well approximated by sparse coefficients under some properly designed system. The wavelet tight frame is such a widely used system due to its capability for sparsely approximating piecewise-smooth functions, such as medical images. However, using a fixed system may not always be optimal for reconstructing a variety of diversified images. Recently, the method based on the adaptive over-complete dictionary that is specific to structures of the targeted images has demonstrated its superiority for image processing. This work is to develop the adaptive wavelet tight frame method image reconstruction. The proposed scheme first constructs the adaptive wavelet tight frame that is task specific, and then reconstructs the image of interest by solving an l 1 -regularized minimization problem using the constructed adaptive tight frame system. The proof-of-concept study is performed for computed tomography (CT), and the simulation results suggest that the adaptive tight frame method improves the reconstructed CT image quality from the traditional tight frame method.

  13. Gas-Water Flow Behavior in Water-Bearing Tight Gas Reservoirs

    2017-01-01

    Full Text Available Some tight sandstone gas reservoirs contain mobile water, and the mobile water generally has a significant impact on the gas flowing in tight pores. The flow behavior of gas and water in tight pores is different than in conventional formations, yet there is a lack of adequate models to predict the gas production and describe the gas-water flow behaviors in water-bearing tight gas reservoirs. Based on the experimental results, this paper presents mathematical models to describe flow behaviors of gas and water in tight gas formations; the threshold pressure gradient, stress sensitivity, and relative permeability are all considered in our models. A numerical simulator using these models has been developed to improve the flow simulation accuracy for water-bearing tight gas reservoirs. The results show that the effect of stress sensitivity becomes larger as water saturation increases, leading to a fast decline of gas production; in addition, the nonlinear flow of gas phase is aggravated with the increase of water saturation and the decrease of permeability. The gas recovery decreases when the threshold pressure gradient (TPG and stress sensitivity are taken into account. Therefore, a reasonable drawdown pressure should be set to minimize the damage of nonlinear factors to gas recovery.

    It was reported that hamstring muscle tightness may increase mechanical loading on the lumbar spine. Therefore, we attempt to decrease tightness in the leg muscles in pediatric patients. Forty-six pediatric patients with spondylolysis underwent rehabilitation. We applied active stretching to the hamstrings, quadriceps, and triceps surae. Tightness in each muscle was graded as good, fair, or poor. We educated each patient on how to perform active stretching at home. They were re-evaluated for muscle tightness 2 months later. Tightness at baseline and after 2 months was as follows: for the hamstrings, good in 3 patients, fair in 9, and poor in 34 and significant improved after 2 months (p<0.05), with improvement by least 1 grade seen in 86% of patients with fair or poor at baseline; for the quadriceps, 7, 3, and 30 patients had good, fair and poor, with significant improvements in 72% (p<0.05). For the triceps surae, 6, 3 and 10 patients had good, fair and poor, which improved significantly (p<0.05). Home-based active stretching was effective for relieving muscle tightness in the leg in a pediatric population. Adolescent athletes should perform such exercise to maintain flexibility and prevent lumbar disorders. J. Med. Invest. 64: 136-139, February, 2017.

    Although posterior capsule tightness is believed to cause abnormal contact in the subacromial space, it is not clear whether this tightness changes the contact between the acromion and humeral head. Nine fresh, frozen cadaveric shoulders were used to measure contact pressure on the coracoacromial arch during passive flexion, abduction, and internal and external rotation at 90° of elevation in the scapular plane, as well as horizontal adduction and abduction. The site where the peak contact pressure occurred was also observed. The posterior capsule in the region from 8 to 10 o'clock in the right shoulder was plicated to simulate posterior capsule tightness. Peak contact pressure significantly increased with the tightened posterior capsule during flexion. Although peak contact pressure on the coracoacromial ligament during internal rotation significantly increased after capsule tightening, there was no significant increase in pressure when considering the entire coracoacromial arch. The angle where the peak contact pressure occurred during flexion was not significantly far from the end range. The site of the peak contact pressure in 7 of 9 shoulders was on the lesser tuberosity during flexion, regardless of the posterior capsule tightness. Posterior capsule tightness increased contact pressure mainly on the lesser tuberosity during flexion. The peak contact pressure occurred close to the end range of flexion, mainly on the lesser tuberosity. These findings are useful to understand the contribution of posterior capsule tightness to subacromial contact. Copyright © 2012 Journal of Shoulder and Elbow Surgery Board of Trustees.

    Full Text Available Ultra-tight integration was first proposed by Abbott in 2003 with the purpose of integrating a global navigation satellite system (GNSS and an inertial navigation system (INS. This technology can improve the tracking performances of a receiver by reconfiguring the tracking loops in GNSS-challenged environments. In this paper, the models of all error sources known to date in the phase lock loops (PLLs of a standard receiver and an ultra-tightly integrated GNSS/INS receiver are built, respectively. Based on these models, the tracking performances of the two receivers are compared to verify the improvement due to the ultra-tight integration. Meanwhile, the PLL error distributions of the two receivers are also depicted to analyze the error changes of the tracking loops. These results show that the tracking error is significantly reduced in the ultra-tightly integrated GNSS/INS receiver since the receiver’s dynamics are estimated and compensated by an INS. Moreover, the mathematical relationship between the tracking performances of the ultra-tightly integrated GNSS/INS receiver and the quality of the selected inertial measurement unit (IMU is derived from the error models and proved by the error comparisons of four ultra-tightly integrated GNSS/INS receivers aided by different grade IMUs.

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

    Full Text Available This paper compares and contrasts the policy reform experiences of Poland and Turkey en route to high income. For both countries, globalization has presented unprecedented opportunities to catch up, unleased by integration into European and global markets and the establishment of macroeconomic discipline. These opportunities were reinforced by the creation of economic institutions to strengthen competition and support private entrepreneurship, catalyzed by the convergence process with the European Union. Both Poland and Turkey have shown resilience following the 2008 global crisis, but continued success will require renewed structural reform measures. Dealing with the challenging of aging while at the same time finding a way to sustain productivity growth through greater domestic innovation is shaping Poland’s policy agenda. Turkey's structural and demographic potential as well as its strategic location between the markets of Europe and Asia offers attractive value proposition to investors, which could be further enhanced with improvements in business regulations and economic governance.

    The prevalence of Equine herpesvirus 2 (EHV-2) infections in the horse populations in Poland was investigated. Peripheral blood leukocytes (PBLs) of 139 horses were tested. The animals were divided into four groups: clinically healthy horses, horses suffering from respiratory disorders, mares with a recent abortion and horses with diagnosed ataxia. Thirty-four virus isolates were obtained from leukocytes of the tested animals by cocultivation with equine dermal cells and were identified as EHV-2 by PCR using primers for the gB gene of EHV-2 and/or primers for the sequence located upstream of the gene homologous to the equine interleukin 10 (IL-10) gene. These results indicate that EHV-2 is prevalent in horse populations in Poland. As the virus was most frequently isolated from horses with respiratory disorders its etiological importance may be considered.

    Full Text Available Unilateral defect of pectoral muscle and ipsilateral syndactyly constitute Poland syndrome. Absence or hypoplasia of the breast and nipple, axillary hair loss and dermatoglyphic abnormalities have also been reported in this syndrome. The primary defect could be in the development of the proximal subclavian artery with early deficit of blood flow to the distal limb and the pectoral region, resulting in partial loss of tissue in those regions. However, the association of congenital hemangioma with Poland sequence has not been observed so far. Such an association is being reported here in a 1-year-old infant, second-born of nonconsanguineous parents, who also had polydactyly instead of the documented syndactyly.

    The attempt to estimate the real number of rubella cases in the years 2015-2016 in Poland was presented in this paper. The relations between number of reported cases of measles in 2006-2015y., the number of laboratory-confirmed cases of rubella among cases suspected of measles and the proportion of rubella among patients suspected of measles in the last 10 years as well as the results of serological examination in samples from 74 patients suspected of rubella collected in the first half of 2016 year were analysed. The sera from patients suspected of rubella were collected in cooperation with the State Sanitary Inspection. The analysis of data collected during the study-cases of suspected measles (2006-2016) and rubella infections (in 2016y.) indicated high over-registration of rubella in recent years in Poland, which is associated with a very low rate of laboratory confirmed cases.

    Full Text Available This paper addresses the role masculist groups currently play in fostering resistance to feminist-influenced efforts to advance the autonomy and equality of women in Poland, where the strong influence of the Polish Catholic Church continues to shape attitudes and actions in professional, governmental and civil society spheres. The paper argues that Polish public discourse since 1989 has been strongly dominated by antifeminist rhetoric advanced by masculist groups. This rhetoric is not only used in the media and in political discourse; it also influences legislation and thus hinders efforts to secure a satisfactory level of equality for women, evidenced in struggles over abortion reform, the Convention on Preventing and Combating Violence Against Women, and the trivialisation of rape. The findings of the paper are based on qualitative social research on men’s social movements in Poland between 2009 and 2012 and on qualitative media discourse analysis of articles published between 2009 and 2014.

    Full Text Available Each region in Poland has a different economic potential due to its own specific features. Taking account of the specific nature of individual regions is important for the management of the country as a whole and of its particular regions. Existing disparities in the economic development may lead to many negative phenomena, such as internal migration or regional marginalization. Excessive price and income inequalities may weaken economic growth throughout the country. It is important for the coherence of the whole country that the disparities between regions are not too big. The study determines the consequences of price differentiation for regional development in Poland. The analysis was conducted using the coefficient of variation, correlation coefficient, regression coefficient and medium pace. The regions differ in terms of development, dynamic growth and wages. However, prices are much less diverse.

    Full Text Available In a study of the genus Cetrelia in Poland, four taxa have been identified, two of which, C. chicitae and C. monachorum, are reported for the first time from the country. All taxa differ in chemistry and subtle morphological characters. Cetrelia monachorum is the commonest member of the genus in Poland (237 records, whereas C. chicitae is known only from 6 records. All taxa are endangered, and three, C. cetrarioides, C. chicitae and C. olivetorum, appear to be critically so, thus deserving the category CR; although C. monachorum is the most frequent, it is not common and should be treated as endangered (EN. The distribution of all taxa, their habitat requirements, as well as morphology and secondary chemistry, are discussed.

    2018-01-01

    Full Text Available The study presents the temporal and spatial variability of particulate matter concentration in Poland in the calendar winter season (December-February. The basis for the study were the hourly and daily values of particulate matter PM10 concentration from the period 2005/06 – 2014/15, obtained from 33 air pollution monitoring stations. In Poland, the obligation to monitor the concentration of the finer fraction of particles smaller than 2.5µm in aerodynamic diameter was introduced only in 2010. Consequently, data on PM2.5 concentration refer to a shorter period, i.e. 2009/10 – 2014/15, and were obtained from 23 stations. Using the cluster analysis (k-means method, three regions of comparable variability of particulate matter concentration were delineated. The largest region, i.e. Region I, comprises the northern and eastern central area of Poland, and its southern boundary is along the line Gorzów Wlkp-Bydgoszcz-Konin-Łódź-Kielce-Lublin. Markedly smaller Region II is located to the south of Region I. By far the smallest area was designated to Region III which covers the south west area of Poland. The delineated regions show a marked variability in terms of mean concentration of both PM fractions in winter (PM10: region I - 33 µg·m-3, region II - 55 µg·m-3, region III - 83 µg·m-3; PM2,5: region I - 35 µg·m-3, region II - 50 µg·m-3, region III - 60 µg·m-3 and, in the case of PM10, the frequency of excessive daily limit value.

    2012-12-01

    Full Text Available Introduction: Quality of bathing water is of key importance for bathers’ health, mainly due to the fact, that each year millions of people use bathing sites as places for recreation and sport activities. Most of the bathing sites are of adequate quality of water, but still there are cases of health risk because bathing water is polluted. One of the main health risk factor in bathing water are cyanobacteria and their blooms. Cyanobacteria are microorganisms of morphological features of bacteria and algae. They live in colonies, which in large quantities show up as streaks, dense foam on the water surface. The aim of this paper was to assess the impact of cyanobacteria blooms on health regarding bathing water quality in Poland. Materials and methods: Assessment covered all bathing sites in Poland supervised by Polish National Sanitary Inspection (PIS in the period from 2007 to 2009. The base was data collected during bathing water monitoring conducted by PIS and their formal decisions of bathing bans introduced in response to revealed bathing water pollution. Results and discussion: The results of assessment indicate, that about one-fourth of all bathing bans in Poland was due to cyanobacteria blooms. Conclusions: Every fifth bathing sites located on artificial lake or water reservoir and every tenth on the sea bathing sites were polluted. Average period of bathing ban due to cyanobacteria blooms in Poland varies. Relatively the shortest bathing bans were observed on the sea bathing sites (no longer than one week on average. Much longer were bathing bans on lakes and artificial lakes (one month on average.

    Full Text Available Introduction : Epidemiological data on anaphylaxis have been underestimated both in Poland and worldwide. Aim : To evaluate the prevalence of anaphylaxis in Poland, including a classification by gender, age and residential region. Material and methods : The data used in the analysis were derived from two sources, the National Health Fund records of healthcare services for 2008–2015 (official statistics and a questionnaire-based survey conducted in 2015 on a sample of 305 allergists practicing in different regions of Poland. Results : In 2015, 3144 people received treatment for anaphylactic shock (T78.0, T78.2, T80.5, T88.6 with an estimated prevalence rate of anaphylaxis of 8.2 per 100,000 (8.4 for females and 7.9 for males. The highest prevalence rate was found for women aged 50–54 years (14.5 per 100,000. There was a very large difference in the prevalence of anaphylaxis between rural and urban areas (13.1 vs. 0.8 per 100,000. In 2015, the Polish NHF spent PLN 3.5 million (EUR 835,000 on the management of anaphylaxis. Of the allergists surveyed, 73% had been currently managing patients who had experienced anaphylactic shock. The most common causes of anaphylaxis included insect venom (41.4%, food (29.8% and drugs (17.4%. Conclusions : A central anaphylaxis registry should be established in Poland. This is the only approach that would allow collecting a wide range of reliable information on the cases, management and consequences of anaphylaxis. Ongoing management of patients who have experienced anaphylactic shock should be improved.

    Lipska, Iga; McAuslane, Neil; Leufkens, Hubert; Hövels, Anke

    2017-01-01

    The objective of this study is to illustrate and provide a better understanding of the role of health technology assessment (HTA) processes in decision making for drug reimbursement in Poland and how this approach could be considered by other countries of limited resources. We analyzed the evolution of the HTA system and processes in Poland over the past decade and current developments based on publicly available information. The role of HTA in drug-reimbursement process in Poland has increased substantially over the recent decade, starting in 2005 with the formation the Agency for Health Technology Assessment and Tariff System (AOTMiT). The key success factors in this development were effective capacity building based on the use of international expertise, the implementation of transparent criteria into the drug reimbursement processes, and the selective approach to the adoption of innovative medicines based on the cost-effectiveness threshold among other criteria. While Poland is regarded as a leader in Central and Eastern Europe, there is room for improvement, especially with regard to the quality of HTA processes and the consistency of HTA guidelines with reimbursement law. In the "pragmatic" HTA model use by AOTMiT, the pharmaceutical company is responsible for the preparation of a reimbursement dossier of good quality in line with HTA guidelines while the assessment team in AOTMiT is responsible for critical review of that dossier. Adoption of this model may be considered by other countries with limited resources to balance differing priorities and ensure transparent and objective access to medicines for patients who need them.

    Full Text Available In District Heating Systems (DHS there are significant fluctuations in demand for heat by consumers during both the heating and the summer seasons. These variations are considered primarily in the 24-hour time horizon. These problems are aggravated further if the DHS is supplied by a CHP plant, because fluctuations in heat demand adversely affect to a significant degree the stable production of electricity at high overall efficiency. Therefore, introducing Thermal Energy Storage (TES would be highly recommended on these grounds alone. The characteristics of Large (i.e. over 10 000 m3 TES in operation in Poland are presented. Information is given regarding new projects (currently in design or construction that apply TES technology in DHS in Poland. The paper looks at the methodology used in Poland to select the TES system for a particular DHS, i.e., procedure for calculating capacity of the TES tank and the system to prevent water stored in the tank from absorbing oxygen from atmospheric air. Implementation of TES in DHS is treated as a recommended technology in the Polish District Heating sector. This technology offers great opportunities to improve the operating conditions of DHS, cutting energy production costs and emissions of pollutants to the atmosphere.

Growing importance of education in improving professional opportunities, changing educational aspirations and parents’ support as well as positive internal migration trends were emphasised. Rural regions are still lagging behind urban areas, though optimistic characteristics indicate receding stigmatisation and marginalisation of the Polish country with internal migration of young and educated individuals, including affluent ones (potential luxury goods buyers, to rural areas. In the semi urbanisation and suburbanisation processes the increase of rural population involves mostly areas adjacent to big agglomerations rather than peripheral villages. The study is based on analysis of public statistical Central Statistical Office of Poland data including the National Population and Housing Censuses of 1988, 2002, 2011, supplemented and deepened the Public Opinion Research Center (CBOS opinion poll results in Poland and global reports from the area of urbanization and education.

    2007-07-01

    The paper describes the state of the art in renewable energy sources development. The obligation resulting from the membership of Poland in the European Union as well as from other international agreements in the scope of renewable energy sources development are described. The production of electricity, heat and biofuels in Poland is given and the perspectives of development of particular renewable energy sources in Poland are discussed in the view of potential reserves and other constrains. The economic aspects of renewable energy technologies are shown. The environmental pros and cons of biomass energy development are described. Arguments for development of renewable energy sources use are stated: the decrease of dependence from primary energy sources, the decrease the emission of green house gases and the recovery of agricultural regions of the country. In conclusion it is stated that the significance of renewable energy sources in Polish conditions is constrained to local societies. Their development should be adjusted to conditions predominating in a given region and that wider consumption of renewable energy sources should develop in conformity with sustainable development, so it is necessary to reach agreement between local societies, institutions dealing with environment protection and representatives of power sector.

    Bovine tuberculosis (bovine TB, bTB) is caused by bovine bacilli: Mycobacterium bovis and M caprae The studies conducted in Poland, in the National Bovine Tuberculosis Reference Laboratory in the Department of Microbiology of the National Veterinary Research Institute in Pulawy, show that animal tuberculosis in Poland is also caused by M caprae We here describe the identification and genotypic assessment of 52 isolates of M caprae obtained from Polish cattle and wild animals over the last five years. We show that strains isolated from bison have significant genotypic diversity and are distinct compared with the genotypes of strains isolated from cattle. Similarly, isolates from cattle herds can be highly genotypically variable. Formal designation of the members of the Mycobacterium tuberculosis complex is controversial in Poland; there is a gap in veterinary legislation with regard to bTB and no explicit mention of M caprae causing tuberculosis in animal. © British Veterinary Association (unless otherwise stated in the text of the article) 2018.

    Full Text Available The article presents the impact of the introduction of lower secondary schools on the educational style of the working classes in Poland. This particular reform is seen as one of the elements of change to the education system adapting it to the general parameters of post-Fordism. The author supports the theory of Pierre Bourdieu, which states that society is divided into three social classes (upper, middle and popular and each of them produces a specific lifestyle and style of education. The education style of a class provides individuals with certain dispositions to educational institutions and school careers, which are realised in the form of social practices (selection of specific type of schools, learning techniques, ways of spending time, etc.. The changes taking place in the education system in Poland over the last 15 years, i.e. since the 1999 reform, are similar to processes that occurred in the 1980s and 1990s in western countries. They include the economisation of education, the parameterisation and quantification of educational results, as well as the introduction of market mechanisms for managing and financing state-owned schools. The article is based on individual in-depth interviews conducted during two field studies organised in 2013–2014: Cultural practices of the working class (120 IDIs and Class differences in cultural practices in the North-Eastern Poland (60 IDIs. The findings become the basis of formulating new theoretical and research proposals for the field of education.

    Full Text Available Cultivation of the Burgundy truffle, Tuber aestivum Vittad., has become a new agricultural alternative in Poland. For rural economies, the concept of landscaping is often considerably more beneficial than conventional agriculture and promotes reforestation, as well as land-use stability. Considering examples from France, Italy, Hungary and Spain, truffle cultivation stimulates economic and social development of small, rural communities. Because there is no long tradition of truffle orchards in Poland, knowledge regarding the environmental factors regulating the formation of fruiting bodies of T. aestivum is limited. Thus, knowledge concerning ectomycorrhizal communities of T. aestivum host species is crucial to ensuring successful Burgundy truffle production. We investigated the persistence of T. aestivum ectomycorrhizae on roots of hazel (Corylus avellana L. and oak (Quercus robur L. and checked the host-species influence on community structure of ectomycorrhizal fungi. The study was conducted in an experimental plantation located in eastern Poland and established in 2008. We demonstrated that the number of fungal taxa was not significantly different between oak and hazel. However, the species composition differed between these two host trees. During the three-year study, we observed that species richness did not increase with the age of the plantation.

    Free-living amoebae belonging to the genus Acanthamoeba are the causative factor of many diseases. Among others, they cause Acanthamoeba keratitis (AK), a condition that usually occurs in contact lens wearers, though it is also observed in non-wearers. The number of diagnosed cases of AK increased more than eightfold during 8 years in the USA, and a proportional increase in frequency also occurred in Poland and Europe. Cases of AK are usually diagnosed late, and their therapy is difficult and rarely successful. AK is an uncommon diagnosis in Poland. The increased number of positive cases observed in our laboratory may reflect the growing at-risk population of contact lens wearers. Acanthamoeba as a genus of facultative human parasites is currently classified into 17 genotypes. Isolates belonging to seven genotypes were found to be associated with AK. One genotype in particular, T4, was found to be overrepresented in human disease. The main finding of our study is that in Poland, AK is almost always associated with the T4 genotype.

    Full Text Available Establishing a common strategic framework is a decisive factor in the Ukrainian-Polish relations in the current social and political context. The complexity of the partnership between the two states arise from their geographical location on the borderline between civilizations, the site of historical cataclysms. At the same time, national sovereignty of was always a high priority for both peoples. The recognition of Ukraine’s independence by Poland marked a new stage of rapprochement between Warsaw and Kyiv, the act being evidence of maturity of the Polish political elite. Poland made its best to promote the interest of Ukraine in the international political arena. The article suggests periodization in the history of the Ukrainian-Polish partnership. Ukrainian policy can be modelled on Poland’s experience of the transformation of society. Being a member of the European Union, Poland advocates the idea of European and Euro-Atlantic integration of Ukraine. Increased economic cooperation is one of the aspects of the Ukrainian-Polish partnership. Cooperation at regional level, between local government bodies is also important for the relations between the two states. Step by step, visa regulations are being liberalized, interpersonal contacts broadened. The beginning of the 21st century witnesses a change in political consciousness of Ukrainian and Polish people, who reconsider painful events from their past.

    Full Text Available The analysis of the Polish flora of the order Uredinales is based on a simultaneously published descriptive elaboration (M a j e w s k i 1977, ms. The information on the Uredinales flora of Poland has been compared as far as possible with the data obtained from the analysis of the flora of sever al other countries in Europe with a different type of vegetations. In a chapter devoted to the statistics of the flora of Polish rust fungi the number of genera and species of these fungi in Poland is discussed, as well as their life cycles and host plants. The distribution of Uredinales in Poland is analysed on the basis of the A r w i d s s o n - D u r r i e u classification modified by the author, and particular attention is paid to the depedence of the range of the fungus on its life cycle and the occurrence of the host. Changes in the flora a result of its synantropization are also considered. The Polish Uredinales are divided into several groups on the basis of range, and example of their distribution involving historical factors are discussed.

  14. AGRICULTURAL ORGANIZATIONS IN POLAND – AN ATTEMPT TOWARDS A TYPOLOGY*

    Full Text Available Agricultural organizations play an important role in political decision-making at the local, national, and EU levels. However, it is diffi cult to estimate to what extent the size of public transfers to the Polish countryside is a direct eff ect of these organizations’ activity. The same question applies to farming privileges, which are much more numerous than those for other social groups in rural areas. One of the reasons for this stems from the fact that agricultural organizations in Poland have rarely been examined. The aim of this article is therefore to obtain a structured picture of agricultural organizations in Poland and to search for relations between their legal forms and statutory goals. The main types distinguished here include farmers’ trade unions, employers’ organizations, agribusiness organizations (agribusiness federations and unions, and associations. Taking into consideration the number of members and the thrust of activities, including impact on agricultural policy, the most important agricultural organizations in Poland seem to be the trade unions and agribusiness organizations. The substantive diff erence between them lies in their stated goals. Trade unions primarily indicate goals of a social nature. Federations of agribusiness organizations strive to support their members and promote policy changes, while agribusiness organizations work for the development of specialized farms.

    Poland appears as a new-comer in the domain of nuclear power but in fact previous projects of nuclear power plants existed but were abruptly stopped in the afterwards of Chernobyl. Today almost 90% of the electricity produced in Poland comes from the combustion of coal and lignite. In january 2009 the Polish government decided to include nuclear power in the energy mix with an aim of a 15% share of the electricity production in 2030 and with the first nuclear plant operating in 2020. The path toward this aim is marked out as following. 2009-2010: drawing up of the legal frame, creation of the nuclear safety authority, drawing up of the list of potential sites, and launching of the public debate. 2011-2013: selection of the first site, of the pool of investors, of the reactor technology and the signature of the contract for the first plant. 2014-2015: obtention of the administrative agreements, elaboration of the technical project. 2016-2020: construction of the plant. The polish public opinion favours nuclear energy and there is a kind of competition between different regions to home nuclear power plants. In 2010 Poland signed various collaboration agreements with the Usa, France and South-Korea. Polish authorities are studying the pros and cons of the EPR (EDF - Areva), ABWR (GE/Hitachi) and AP1000 (Westinghouse) reactors. (A.C.)

  16. The influence of educational research on education in Poland

    There is no need nowadays to convince people that modern education cannot function properly without the help of scientific research, and especially of pedagogical research. It is true that there still appear many pedagogical works `inflated by wind', as Comenius expressed it more than three hundred years ago, and these publications may even acquire a temporary popularity. But the general trend towards the development of pedagogy as a discipline based on research has been established for quite some time and is constantly gaining strength in the developed countries. Concurrently, pedagogical disciplines have had increasing influence on the development of education. The question of how these disciplines have developed in Poland and how they have influenced the educational system calls for a broader review, such as to allow one to draw conclusions on how to harmonise more effectively the domain of educational research with that of education. Such a review is the aim of the present paper. The following issues are considered: the functions of educational research, the kinds of educational investigations conducted in Poland, ways of disseminating their findings, and the organisation of research in Poland. The paper ends with a discussion of some of the more important conclusions reached.

    Within a constrained carbon environment, the risks of future natural gas supply, and the need to move to market-based electricity prices, the study team found: (1) the deployment of new nuclear energy in Poland itself is very competitive in the next decade or two; (2) if such generation could be made available to Poland prior to deployment of its own nuclear generation facilities, Poland would benefit from partnering with its Baltic neighbors to import electricity derived from new nuclear generation facilities sited in Lithuania; and (3) Poland appears to be a good candidate for a partnership in the Global Nuclear Energy Partnership (GNEP) as an emerging nuclear energy country.
