Posted in 2017, HISTORY, Issue № 7(61) July 2017 | 0 comments

The paper is devoted to the analysis of the features of operation of the “Open Society” Fund and its activities on the territory of the Russian Federation during the period of 1993-2003. The author assesses the influence of J. Soros’s personal influence on the activities of this fund, including those on the territory of Russia. Previously unpublished archival documents are presented, in defense of the hypothesis that during the considered period, “Open Society” NGO carried out such activities on the territory of the Russian Federation that go beyond its original competence.

INFLUENCE OF VARIOUS CONCENTRATIONS OF NaCl ON GERMINATING ABILITY OF SEEDS OF COMMON FLAX (LINUM USITATISSIMUM L.)

Posted in 2017, Issue № 6(60) June 2017, БИОЛОГИЧЕСКИЕ НАУКИ | 0 comments

The following work reflects the results of the study of the effect of various concentrations of sodium chloride on a number of indicators of early ontogenesis of common flax and namely the germinating ability of seeds, the mass of seedlings, the length of the main root and hypocotyls in dynamics. Seeds and seedlings of Linum usitatissimum were exposed to solutions of NaCl in concentrations of 0.01M, 0.02M, 0.03M, 0.04M and 0.05M for six days. It is shown that salinity stress does not have a unique effect on germinating ability of seeds with a higher concentration of NaCl (0.04 M) has a stimulating effect on this index. At the same time, a 0.02 M sodium chloride solution stimulated the development of the root system of seedlings, but did not affect the development of the aerial parts of plants. The results of the work enable us to conclude that the effect of NaCl solutions on common flax is determined solely by the specific concentration of the given substance.

CONCEPTUAL PROVISIONS OF DOSIMETRIC MODEL OF EXTERNAL IRRADIATION OF SOIL MESO-FAUNA AT ACUTE PHASE AFTER RADIOACTIVE LOSSES

Posted in 2017, Issue № 6(60) June 2017, БИОЛОГИЧЕСКИЕ НАУКИ | 0 comments

The article considers the features of the radiation situation in the natural environment at the initial phase of radioactive fallout and shows the absence of software tools for dosimetric assessment for biota in the first months of the radiation situation formation. The authors substantiate the necessity for the development of a software tool for estimating the irradiation of soil biota, as one of the exposed groups of organisms. The main assumptions of the dosimetric model of irradiation of soil meso-fauna, including radiation sources and radiation effects, are formulated.

ECOLOGICAL AND EPIDEMIOLOGICAL PROBLEMS OF TOXOCAROSIS IN RUSSIA

Posted in 2017, Issue № 6(60) June 2017, БИОЛОГИЧЕСКИЕ НАУКИ | 0 comments

We conducted ecological and epidemiological assessment of the situation related to toxocarosis, as well as the analysis of the toxocarosis distribution in Russia, and comparison with the statistical data of other countries. The results of the research showed that toxocarosis is a serious problem – it is widely spread all over the world, which contributes to an unfavorable epidemiological situation. Recent studies have shown a relatively low prevalence of toxocarosis in Western Europe. The highest incidence rate is recorded in tropical countries (Bali, West Indies). It is established that toxocarosis is one of the most widespread diseases and a very dangerous zoonoses helminthiases affecting a person.

METRIC SPACE OF UNLIMITED CONVEX SETS AND UNLIMITED POLYHEDRON

Posted in 2017, Issue № 5(59) May 2017, PHYSICS AND MATHEMATICS | 0 comments

In the paper there is a definition of metric space H(K) the unlimited closed convex subsets of Banach space X, having the same recessive K. There is a Hausdorff metric that is used as a distance. It is established in this paper that the properties of a metric space H(K) are different from the properties of the metric spaceof convex compacts with Hausdorff metric. It is established that the theorem similar to the theorem of approximation of convex compacts polyhedrons is wrong. That is not each element of metric space H(K) can be approximated by the generalized polyhedrons, which are the analogues of the normalpolyhedrons.

The paper introduces the concept of a generalized polyhedron in the following way. The set of elements H(0)+K are known as generalized polyhedrons.

The criterion of approximation is derived. In order for the element of the space H(K) could be approximated by generalized polyhedrons in the Hausdorff metric it is necessary and sufficient that its basic function was evenly continuous.

APPLICATION OF HIGH-FREQUENCY EFFECTS TO REMOVE GROUND ADHESION ON MACHINES WORKING BODIES

Posted in 2017, AGRICULTURE, Issue № 5(59) May 2017 | 0 comments

This article examines the use of piezoceramic emitters for controlling adhesion of soil to the working bodies of earth-moving machines. Also an experiment was performed and the experimental data was obtained. After further processing of patterns a graphical interpretation of the effect of piezoceramic emitters was obtained. Subsequently, it was concluded that the use of piezoceramic emitters is more preferable in terms of compactness and equal spacing on the surface of the working body than, for example, the use of the currently existing means for heating the ladle or vibration exposure. It has been shown that the technical performance of the machines with the intensifying device to reduce adhesion of soils when working on wet ground at a negative temperature is 1.2…1.4 times greater than the machines not equipped with such a device, i.e. there is economic impact of their implementation due to increased productivity.

STRUCTURAL REINFORCEMENT OF ARCHITECTURAL MONUMENTS USING POLYMER COMPOSITE MATERIALS

Posted in 2017, ARCHITECTURE, Issue № 5(59) May 2017 | 0 comments

The issues on structural reinforcement of columns using bands made of polymer composite material and carbon fiber lamellae are considered in this paper. A particular attention is paid to strength and corrosion resistance of the materials used, and their ability to keep the appearance of the architectural monument. It is possible to strengthen the column by gluing strips made of composite material in a stretched cross-section area in different directions, at different angles of fabric winding, both continuously and discretely, besides it is necessary to calculate the areas where it is necessary to do. The further development in this direction is expected both in construction and in architecture, with the usage of new innovative materials that can be applied in other areas, for example, medicine, aviation, helicopter industry, and space industry.

IN VITRO ANTIPROLIFERATIVE POTENTIAL AND ANTIOXIDANT CAPACITY OF NEW COORDINATION COMPOUNDS

Posted in 2017, Issue № 5(59) May 2017, MEDICINE | 0 comments

In the present study the ability of coordination compounds TIA-90, TIA-91 and TIA-93 to induce the inhibition of proliferation in the epithelial cells of pancreatic carcinoma of the BxPc-3 line were investigated. Their cytotoxicity against normal kidney epithelial cells of Madin Darby dog’s MDCK line was also evaluated. The viability of cancer cells was determined by the Alamar Blue test using the redox indicator of resazurin. To identify the antioxidant properties of TIA-90, TIA-91 and TIA-93 anticancer agents, we used a relatively simple but reliable ABTS method. Obtained results showed that the compounds TIA-90 and TIA-93 have greet antiproliferative and antioxidant potentials. The cytotoxic activity of these compounds against normal cells of the MDCK line is lower than that on tumor cells, which indicates the prospect of their use as antitumor agents. However, additional studies are need to evaluate the mechanisms of action of these compounds, as well as their possible adverse effects in other bioassay systems and animal models.
