Quantitative data on the feeding of Cyclops strenuus Fischer and Cyclops viridis Jurine. [Translation from: Trudy saratov.Otd.vses.nauchno-issled.Inst.ozer.rech.ryb.Khoz. 1, 163-176, 1951.]

Cyclopids, exactly in the same way as daphnids, significant component in the nutrition of plankton-f and the young of the majority of fishes. It is established that the food spectrum of cyclopids is extremely broad: daphnids, planarians, Copepodite stages of copepods (cannibalism), rotifers, protists, bacteria, phytoplankton and so on. It is clear that the problem of studying these or other components of feeding in the general food spectrum can be definitely resolved only after obtaining exact quantitative data on the feeding of cyclopids. This article attempts to fill the gap in the study of the quantitative side of the feeding of cyclopias; in it is investigated the size of the 24-hour ration of cyclopids feeding on protists, the dependence of the ration on some factors of the external medium, and the difference of 24-hour consumption per unit weight of tody with two species of cyclopids (Cyclops strenuus and Cyclops viridis)

Umělecké jazykové prostředky v překladu.

This work in the field of the translation theory, extending to the translation practice, focuses on exploring literary terms and techniques, that participate in the construction and poeticisation of the literary text. Very often these terms make problems in the process of translation text from one language to another. The aim is localizing (with regard to its contextual involvement), analysis and subsequent selection of the most appropriate translation solutions of these terms. The work focuses on the translation of these literary devices not only in plan of Slavic languages (Russian, Czech, Slovak), but also takes into account the aspect of non-Slavic languages (English).Práce z oblasti teorie překladu, s přesahem i do překladatelské praxe se zaměřuje na zkoumání uměleckých jazykových prostředků, které se podílejí na výstavbě a poetizaci díla; a mnohdy činí problémy v procesu převodu textu z jednoho jazyka do druhého. Cílem práce je lokalizace (s přihlédnutím k jejích kontextovému zapojení), analýza a následné výběr nejvhodnějšího překladatelského řešení těchto jednotek. Práce se zaměřuje na překlad těchto jevů nejen v plánu slovanských jazyků (ruský, český, slovenský), ale zohledňuje i aspekt jazyků neslovanských (anglický).Ústav východoevropských studiíInstitute of East European StudiesFaculty of ArtsFilozofická fakult

Gods and Believers in "Mrs. Dalloway" (a Cognitive Study of V. Woolf’s Religious Concepts)

The article deals with topical issues of religious worldview and its interaction with national culture and individual artistic worldviews as crystallized in the language of literature. It presents a vigorous study of some religious concepts in Virginia Woolf’s artistic worldview which have previously been overlooke

Investigation of the effects of low-temperature non-equilibrium plasma treatment

The article considers the issue of archaeological leather conservation with the application of new material treatment methods. The work includes a microscopic examination of leather archaeological articles, a study of the microstructure of archaeological leather with various natural origins, and an identification of archaeological leather based on its generic origin. The authors investigated of the influence of non-equilibrium low-temperature plasma treatment on the structural transformations of leather articles, and a study of its influence on the physical, mechanical and hygienic properties of archaeological leather articles prior to conservation.peer-reviewe

Trace element contamination in the arms of the Danube Delta (Romania/Ukraine): Current state of knowledge and future needs

This paper provides the first critical synopsis of contamination by selected trace elements in the whole Danube Delta (Romania/Ukraine) to: identify general patterns of contamination by trace elements across the Delta, provide recommendations to refine existing monitoring networks and discuss the potential toxicity of trace elements in the whole Delta. Sediment samples were collected between 2004 and 2007 in the three main branches of the Delta (Chilia, Sulina and Sfantu Gheorghe) and in the secondary delta of the Chilia branch. Samples were analyzed for trace elements (Cd, Co, Cr, Cu, Ni, Pb, V, and Zn) and TiO2, Fe2O3, MnO, CaCO3 and total organic carbon. Cluster analysis (CA) and Principal Component Analysis (PCA) showed that levels of Cd, Cu, Pb, and Zn were influenced by anthropogenic activities. At the opposite, concentrations of Cr and Ni largely originated from the weathering of rocks located in the Romanian part of the Danube catchment and naturally rich in these elements. Data analysis using Self- Organizing Maps confirmed the conclusions of CA/PCA and further detected that the contamination tended to be higher in the Chilia and Sulina arms than in the Sfantu Gheorghe arm. The potential ecological risks due to trace element contamination in the Danube Delta could be identified as moderate and localized, provided that the presence of the natural sources of Cr and Ni was properly considered. The available results suggest that monitoring sediment quality at the mouths of Sulina and Sfantu Gheorghe arms is probably enough to get a picture of the sediment quality along their entire lengths. However, a larger network of monitoring points is necessary in the Chilia and secondary Chilia delta to account for the presence of local point sources and for the more complex hydrodynamic of this part of the Danube Delta

Influence of pressure ratio on GTU and CCP efficiency

In this work ways of increase in efficiency of gas-turbine units (GTU) are analysed. Besides commercially mastered high reference temperatures of gases in front of the gas turbine (GT) – to 1500-1600 °C, also other factors influencing efficiency of GTU, in particular, pressure ratio are considered. The analysis of optimum values of pressure ratio and the analysis of influence of intermediate gases heating and intermediate air cooling are carried out. The experience of developments of GT with high pressure ratio is given.В работе проанализированы способы повышения эффективности газотурбинных установок (ГТУ). Помимо коммерчески освоенных высоких начальных температур газов перед газовой турбиной (ГТ) – до 1500-1600°С, рассмотрены и другие факторы, влияющие на эффективность ГТУ, в частности, степень повышения давления. Проведен анализ оптимальных значений степени повышения давления, влияние промежуточного подогрева газов и промежуточного охлаждения воздуха. Приведен опыт разработок ГТ с высокой степенью повышения давления
