The assessment of the groundwater resource sustainability in the European part of Russia

Abstract

This article presents a method to assess the resistance of groundwater resources to anthropogenic impact and the fresh groundwater withdrawal as well as the results of such assessment for different territories of the country ranging from a federal district or a region to an artesian basin. The assessment was carried out with the help of the system of indicators and indexes of groundwater resource sustainability under the influence of groundwater withdrawal developed by the author.

CHPP related anthropogenic impact zones

Abstract

This article offers a concept of an integral CHPP related anthropogenic impact zone (AIZ), representing a complex of industrial units, organizations and communications, which support the life cycle of a CHPP. The author conducted an analysis of the basic features of an integral CHPP AIZ and its elements. This concept may have a certain theoretical significance in solving optimizing environmental problems at the level of individual territories and the country in whole.

A study of the statistic properties of the distribution of thermokarst lakes in the West Siberian cryolithic zone on the basis of satellite images

Abstract

The location of thermokarst lakes on the research territory in the permafrost zone of Western Siberia is identified with the use of satellite images. The statistical data analysis shows that the empirical laws of spatial distribution of the lake centers on the plane correspond to the uniform distribution law.

The geochronology of the Holocene vegetation deve¬lopment in the South-east Baltic region (based on the results of a paleogeographic study)

Abstract

This article presents the results a of complex palaeogeographical study of Velikoye peat bog (the Šešupė River basin, the Kaliningrad region). The pollen analysis accompanied by radiocarbon dating, makes it possible to reconstruct the vegetation development, on the basis of which the climate changes in the South-east Baltic region over the Atlantic-Subatlantic periods of the Holocene can be tracked.

The identification of the predominant age of the crystalline basement of continental and ocean platforms

Abstract

This article presents the evidence of the ancient origin of crystalline basement of the platform areas of the Earth developed as a result of global volcanism in the Hadean (more than 4 Ga). In the late Mesozoic-early Cenozoic, another outbreak of volcanism and dehydration of subsoils led to a significant subsidence (8—10 km) of continental masses and the formation of the World Ocean.

The species composition and the biotopical groups of the gastropoda in the pond of Kaliningrad

Abstract

This article considers the species composition, species biotopic distribution, nutrition, and zoogeographic characteristics of gastropoda in Kaliningrad ponds. The author shows the interplay of ecological factors that determine the species composition of molluscs. The article also presents the data on the impact of the invasive species Potamopyrgus antipodarum (Gray, 1843) on the malacofauna of water bodies.

СA comparative analysis of bioflavonoid accumulation by Trifolium pratense in the Kaliningrad region

Abstract

This article examines the influence of environmental factors on the polyphenol accumulation of the red clover (Trifolium pratense L.) in the coastal and continental areas of the Kaliningrad region. The influence of temperature, light, and mineral nutrition factors on the accumulation activity of anthocyanins, leucoanthocyanidins, and catechins is determined. The coastal and continental area plants did not show any significant differences in the content of the examined polyphenol classes.

The steroid regulation of immune memory

Abstract

The solution to the problem of immune memory generation in pathological processes of various kinds is a subject of theoretical investigations of the biomedical science. The role of immune memory in different diseases is ambiguous and may have both positive and negative consequences. It necessitates the search for effective ways of its regulation (by either endocrine or external influence), which, in some cases (infectious and tumourous disease), aim to strengthen and, in other cases (autoimmune diseases and allergy), to suppress (weaken) the immune processes. The factors affecting the formation of immunological memory are numerous and varied. The steroid hormones are considered the most abundant group of biologically active agents. The influence of these agents on proliferation, differentiation and apoptosis of immune system cells is being intensively studied. This review analyses the data on the role of steroid hormones in the immune memory regulation obtained in the recent researches.

The features of the chemical composition of integumentary loams in the Vaytka-Kama loess province

Abstract

This article presents the chemical analysis of integumentary loams in the eluvial landscapes of the Vyatka-Kama Cis-Ural region. The authors focus on the features of microcell migration and the composition of petrogenic oxides. The inheritance of the microcell dispersion features of integumentary loam from the bedding rock was established on the basis of statistics.

A study into the effectiveness of modifying primer protective layers in St3 steel in case of corrosion initiated by Aspergillus niger

Abstract

Mould fungi are of particular interest as metal destroying microorganisms. This paper presents the results of a study on a number of organic compounds as St3 steel corrosion inhibitors and fungicides against the Aspergillus niger. Electrochemical, microbiological and gravimetric analyses helped increase the protective action of modified primer on steel corroding under the effect of Aspergillus niger.

Confessional space as a subject of social geography

Abstract

This article considers the notion of confessional space as a subject of social geography. Confessional space is represented as an interrelation of several elements: the religious part of population, the religious-cultural infrastructure, and the attributive-ceremonial component. The authors analyze the manifestation of these elements in different qualitative areas of the territory.
