Temperature effect on the current-voltage characteristic fill factor for the silicon solar cells
PublikacjaW pracy przedstawiono badania wpływu temperatury pracy krzemowych ogniw fotowoltaicznych na wartość współczynnika wypełnienia charakterystyki prądowo- napięciowej (FF). Efekty dyfuzyjne w obszarze złącza oraz rekombinacja nośników ładunku ograniczają wartość współczynnika wypełnienia charakterystyki. Spadek tej wartości wynika głównie ze wzrostu wartości rezystancji szeregowej rs. Na rezystancję szeregową składają się: opór emitera...

The formal safety assessment and influence of human factor in application to chosen ship's type
PublikacjaTragedia jednego ze statków typu ro-ro pokazała podatność tego typu statków na utratę stateczności, przewrócenie się, a w ostateczności zatonięcie. Wszystkie ro-rowce charakteryzują się małym zanurzeniem, a wynurzona część kadłuba podatna jest na działanie wiatru. Jeżeli dodatkowo w takich warunkach dochodzi element nieprawidłowego rozmieszczenia pojazdów i ich słabego zamocowania to groźba przesunięcia ładunku staje się realna....

Strength deterioration of 26H2MF and 34HNM steels used in ship engines: hydrogen factor
PublikacjaBadano podatność stali 26H2MF i 34HNM poddanych różnej obróbce cieplnej na niszczenie wodorowe. Badania wykonano metodą powolnego rozciągania z szybkością 10-6 s-1. Określano wytrzymałość, wydłużenie, przewężenie i energię zniszczenia. Stwierdzono znaczna degradację w 0,01 M kwasie siarkowym z dodatkiem arszeniku. Wykazano istnienie korelacji między obróbką cieplną i stopniem degradacji. Efekty przypisano pułapkowaniu wodoru.

Hydrophobic and hydrophilic properties of pollutants as a factor influencing their redistribution during snowpack melt
PublikacjaGlaciers accumulate organic pollutants delivered by snow. However, our understanding of the exact dynamics of organic pollutants in the snowpack relies primarily on laboratory experiments and mathematical models. To fill the gap related to the detailed field data, we have conducted observations of melting snow profiles in two locations and three different stages of melting on one High Arctic glacier, as well as in superimposed...

Exploring the factor structure and the validity of the abbreviated Basic and Earning Self-Esteem Scales
PublikacjaThe original longer versions (Forsman & Johnson, 1996) and abbreviated versions of the Basic and Earning Self-Esteem Scales have been used in clinical and non-clinical settings, but little is known about the factor structure and the validity of these scales in their abbreviated forms. The original longer versions of the scales comprise several dimensions, but both abbreviated versions of the scales have been interpreted as if they...

Interaction of the conserved region 4.2 of sigma(E) with the RseA anti-sigma factor
PublikacjaEo-E RNA polymerase transcribes a regulon of folding factors for the bacterial envelope and is induced by physical and chemical stresses. The RseA anti-sigma factor inhibits the activity of Esigma(E) RNA, polymerase. It is shown here that the N-terminal portion of sigma(E), residues 1-153, binds core RNA polymerase. RseA interacts with residues 154-191 of sigma(E), a site that is homologous to region 4, the sigma factor binding...

Constant-Factor Approximation Algorithm for Binary Search in Trees with Monotonic Query Times
PublikacjaWe consider a generalization of binary search in linear orders to the domain of weighted trees. The goal is to design an adaptive search strategy whose aim is to locate an unknown target vertex of a given tree. Each query to a vertex v incurs a non-negative cost ω(v) (that can be interpreted as the duration of the query) and returns a feedback that either v is the target or the edge incident to v is given that is on the path towards...
