Abstract

W polskich elektrowniach pracuje ponad 50 bloków klasy 200 MW, głównie ponad czterdziestoletnich, których eksploatacja staje się coraz bardziej kosztowna z powodów funkcjonalnych i środowiskowych. Jednostki te albo przeszły już kosztowną modernizację, dostosowującą je do wymagań obowiązującej od 2016 r. dyrektywy IED (o emisjach przemysłowych), albo uzyskały w tym zakresie derogacje. Jednak najpóźniej od 2021 r. będą musiały spełniać one jeszcze bardziej restrykcyjne normy, tzw. konkluzje BAT dotyczące emisji zanieczyszczeń. Wymagają więc kolejnej modernizacji. Problematyczna jest także znaczna ilość dwutlenku węgla, który emitują. Narodowe Centrum Badań i Rozwoju, dostrzegając ten problem, podjęło decyzję o wdrożeniu programu „Bloki 200+. Innowacyjna technologia zmiany reżimu pracy bloków energetycznych klasy 200 MWe z uwzględnieniem trybu zamówienia przedkomercyjnego”. NCBR, przy czynnym zaangażowaniu uczestników sektora, planuje pozyskać niskonakładową metodę modernizacji bloków energetycznych. Ma ona nie tylko przedłużyć ich żywotność, ale także umożliwić eksploatację przy częstszych zmianach obciążenia, wymuszonych coraz większym udziałem OZE w Krajowym Systemie Elektroenergetycznym. Program ma na celu także wdrożenie w wymiarze krajowym rozwiązań zaczerpniętych z modelowego trybu finansowania badań amerykańskiej agencji DARPA. Planowane jest również przetestowanie nowatorskiego trybu zamówień przedkomercyjnych w dziedzinie nowych technologii. Artykuł wyjaśnia przede wszystkim, na czym polega nowe podejście NCBR do finansowania badań rozwojowych w dziedzinie elektroenergetyki (idea „państwo jako inteligentny zamawiający”). Analiza przedstawionego modelu programu odpowiada także na pytanie, czy pozyskanie innowacyjnej metody modernizacji bloków energetycznych ma szansę przyczynić się w znacznym stopniu do zapewnienia bezpieczeństwa energetycznego w Polsce w perspektywie krótko- i średnioterminowej.

Abstract

The paper examines the issues of epidemiology, conditions, and treatment of eating disorders in men which are not widely recognised in either Polish and other International research. The aim of this paper is to provide an narrative overview of published research to date on the epidemiology, determinants and treatment of eating disorders in males, to discuss some of the differences reported in studies of self-identified gender disparities, and differences in comparison to the literature on female eating disorders. The prevalence and extent of the issue is underestimated by those affected and by clinicians. Consequently, men suffering from eating disorders (EDs) are less likely to be recognised or to receive appropriated timely help. This paper is based on a narrative review analysis of research reports on EDs. The authors discuss the issue of EDs in the context of gender, indicating how self-identified gender can affect clinical presentation (including somatic self- -perception, and the methods employed and motives in striving for a ‘perfect’ figure) and how these relate. Both the methods used in collecting data on eating disorders and the precision of diagnostic criteria for recognising eating disorders (mainly anorexia nervosa and bulimia nervosa) (both on the DSM and ICD systems) are based largely on research conducted in female clinical populations. Analysis of the empirical material to date leads us to assume that symptoms of EDs in men are more often (than in the case of women) related to (self)stigmatisation, difficulties in obtaining a correct diagnosis, coexistent body dysmorphic disorders, substance addictions, and greater physical activity.’

Abstract

The aim of the present study was to investigate whether the anterior chamber constitutes part of the normal migratory pathway of CD4+ and CD8+ lymphocytes in cattle and swine. The cells obtained from aqueous humor of cows and pigs were stained for CD4 and CD8 receptors, and subsequently analyzed with flow cytometry. The mean percentage of CD4+CD8-, CD4-CD8+ and CD4+CD8+ cells within the total lymphocyte population of the bovine anterior chamber was, respectively, 17.88, 12.64 and 27.26%. In turn, the mean values of these parameters in pigs were 1.77, 38.48 and 17.45, respectively. Among bovine and porcine CD4+CD8+ cells prevalent were those displaying CD4lowCD8low and CD4lowCD8high phenotypes, respectively. The results suggest that the anterior chamber in cattle and swine is an element in the normal migratory pathway of CD4+, CD8+ and CD4+CD8+ cells. Furthermore, the contribution of these subsets in the anterior chamber lymphocyte population can differ considerably between animal species.

Abstract

This article is a proposal of a new edition of the text of Agnus Dei contained in the manuscript kept in the Kórnik Library (manuscript No. BK 101), consisting of comprehensive transliteration, scientific transcription with linguistic commentary and - which is a significant novelty compared to the previous editions of historical texts - philological translation. The combined analysis of language and versification allowed for a fuller reading of the meaning of the text and - in consequence - the drafting of a new transliteration and transcription, in many places different from the one published by M. Muszyński in 1968. The article contains a description of the codex in which the presented text is written, a short history of the European and Polish cult of wax medallions consecrated by the Pope, as well as the Latin text of a poem about Agnus Dei, which may be the source (although not necessarily a direct one) of the Polish text.

Abstract

Yield and the course of crop vegetation are the result of the interaction between the level of cultivation technology and the course of meteorological conditions, which are a variable production factor. The aim of the study was to quantify the effect of meteorological conditions on the course of development stages and yield of winter wheat cultivated in two technological variants (A1 – medium-intensive and A2 – intensive). The paper uses data on yield and timing of winter wheat development stages from four Experimental Stations for Variety Testing (Pol. Centralny Ośrodek Badania Odmian Roślin Uprawnych – COBORU) experimental stations from 2007–2016 located within the Upper Vistula and Upper Oder River basins. To determine the dependence of the length of development stages of winter wheat on the values of selected meteorological elements, the linear regression metod, correlation coefficient. It was found that the lengths of the selected developmental stages are positively correlated with air temperature and negatively correlated with the sum and number of days with precipitation in these stages. A 1°C increase in air temperature resulted in a shortening of the shooting – heading and heading – full maturity periods by 2.5 and 2.8 days respectively. An increase of 100 mm of precipitation in the periods sowing – full maturity and heading – full maturity resulted in an increase of these periods by 5 and 10 days. Increasing the number of days with precipitation by 10 days in the sowing – full maturity and heading – vax maturity stages resulted in extending these stages by 4.1 to 4.4 and 7 to 7.5 days for the A1 and A2 cropping technologies, respectively.
