The investigation into airborne fungal spore concentrations was conducted in Szczecin (Poland) between 2004 and 2009. The objective of the studies was to determine a seasonal variation in concentrations of amerospores on the basis of meteorological parameters. The presence of spores in Szczecin was recorded using a volumetric method. Fungal spores were present in the air in high numbers in late...

The denaturation transition which takes place in circular DNA is analyzed by extending the Poland-Scheraga (PS) model to include the winding degrees of freedom. We consider the case of a homopolymer whereby the winding number of the double-stranded helix, released by a loop denaturation, is absorbed by supercoils. We find that as in the case of linear DNA, the order of the transition is determi...

1 Comment on " Why is the DNA denaturation transition first order? " Recently, Kafri, Mukamel and Peliti (KMP) [1] extended the classical Poland-Scheraga (PS) model for the denaturation transition of DNA [2]. According to PS, the energetic binding of bases in the double helix competes with the entropic contribution of denatured loops, implying that the nature of the transition depends on the ex...

The article investigates the role of bank capital in financing reproduction processes and increase of economic growth indicators, considers the essence of the concept of “bank capitalization”, determines the structure and main sources of bank capital increase. Taking into account the fact that Ukraine and Poland have similar vectors of economic development, the current practices of increasing t...

the aim of the current investigation was to evaluate the sedentary lifestyle of the polish population and its link with prolonged sitting in light of individual and environmental factors.the sample consisted of 1505 polish people between 18 and 64 years old. the computer-assisted telephone interview (cati) survey was conducted with the polish version of international physical activity questionn...

due to the fact that a considerable part of europe, including some regions of poland, isconsidered to be deficient in selenium, it seems necessary to develop a selenium map for different regions of poland, which will be used in future to prepare a prophylaxis programme against selenium deficiency inanimals. the aim of the study was to determine selenium content in selected organs (liver and kid...

The Poland-Scheraga (PS) Model is one of the most celebrated applications of statistical physics to biology. By relying on basic laws of statistical phase transitions the PS model describes the denaturation of DNA strands as a function of temperature according to a minimal set of assumptions. The basic model makes the prediction of a second-order phase transition in the order parameter of the s...

background the prevalence of newly-diagnosed cases of chronic hepatitis is decisive for the overall incidence rate of hepatitis b observed in poland. objectives we aimed to determine the chronic hepatitis b incidence trends in poland, taking into consideration the ages, genders, and environments of the patients. methods the study is based on aggregated data from polish descriptive epidemiologic...
