We fit the single-hadron transverse-momentum spectra measured in Pb+Pb collisions at sNN = 2.76 TeV with the blast-wave model that includes production via resonance decays. Common fit to pions, kaons, (anti)protons, and lambdas yields centrality dependence of the freeze-out temperature and transverse expansion velocity. In the most central collisions we see T= 98 MeV and 〈v〉 = 0.654. The K∗ resonance fits into this picture but the f meson might freeze-out a little earlier. Multi-strange baryons seem to decouple at higher temperature and weaker transverse flow. Within our model we observe hints of chemical potential for the charged pions. © 2016 IOP Publishing Ltd.

Electoral geography has been established as an important part of political geography in the post-communist countries of Central and Eastern Europe in the last twenty years. Geographers endeavour to contribute to increasing electoral studies focusing on the spatial context of elections. The aim of this article is to identify the main research trends in current electoral geography around the world. We emphasize the approaches of relevant researchers to electoral geography's most important issues. The article offers a basic review of contemporary leading studies and the main research directions in electoral geography. © Institute of Geography SAS.

We explore the influence of deuteron formation in the late stage of nucleus-nucleus reactions on the fluctuations observed in the final net-proton yields around midrapidity. At each investigated energy, the produced (anti)proton yield at chemical freeze-out is assumed to fluctuate according to a Poisson distribution and in each event the probability for deuteron formation by coalescence is proportional to (dNproton/dy)2. The protons that are then clustered in deuterons are usually not included in the experimental measurement of the net-proton fluctuations, therefore, we subtract these clustered protons from the final state proton number for the calculation of the net-proton fluctuations (the same is done in the antiproton sector). Due to the nonlinear deuteron formation probability the resulting distribution is not a Skellam distribution, but shows the interesting feature of a decrease in the kurtosis κσ2 and a local maximum in the skewness Sσ observables as the collision energy decreases. © 2015 American Physical Society.

The characterization of the physical structure and the quality of a habitat is becoming more important in the environmental planning and management of rivers. The Water Framework Directive which views morphology as a basic component of rivers, requires that the EU member states evaluate hydromorphological quality as a part of the ecological assessment of their water bodies. The purpose of this paper is to assess the natural conditions on the River Váh in the upper Liptov region by means of hydromorphological and botanical survey of the river corridor and to contribute to its conservation and restoration. The results - more than 20 detailed maps, field records and photographs - give a precise and timely picture of the river channel's natural condition and its morphological features, including information about the abundance of trees and shrubs, but also a list of the sources of pollution and illegal waste dumps and the localities with invasive plant species. This information not only assists as a resource for any further research on fluvial processes, but it is also an important part of any environmental planning and management process, whether it is a structural engineering, revitalization or a conservation project. © Geografický ústav SAV/Institute ot Geography SAS.

Prevalence of functional disorders of the musculoskeletal apparatus in the school population is a precondition for structural changes and often the cause of invalidity in adulthood in Slovakia. Also statistics of health insurance companies correspond with this fact. Therefore, early diagnosis and prevention in children and youth carried out through exercise programs are one of the options of prevention of these facts in later age. The study presents a partial objective and tasks with the intention of the intervention exercise programme to influence selected determinants of the muscul oskeletal system in female pupils of fourth grades at secondary schools within lessons of physical education, with the possibility to extend the knowledge about the effect and significance of exercise programs as a part of physical education. Our selected test group consisted of female fourth grade pupils at secondary schools in L. Mikuláš. As to methods for obtaining data we used standardized methods of evaluation of selected musculoskeletal apparatus determinants based on pedagogical and medical practice. We processed the obtained qualitative and quantitative data of evaluation of the dynamic function of the spine with the aid of the parametric t-test for dependent observation and the Chi-square test for overall muscle balance. Results significantly (p < 0.01) demonstrated the impact of the selected exercise program with selected equipment on the determinants of the muscular system in the tested group of female pupils, whereby we confirmed the effectiveness of the exercise program on spine dynamic function and overall muscle balance, as well as of the possibilities of its inclusion in physical education and sports.
