Diffuse matter and cosmogony of stellar systems in researches by ***

Research in Astronomy and Astrophysics 2018年第8期18卷 89-96页

作者： natalia ivanovna bondar Crimean Astrophysical Observatory RAS Nauchny298409Russia

The main topic of long-term researches by G.A. Shajn is the nature of diffuse matter, its dis- tribution in the Galaxy and extragalactic systems, interaction with the interstellar medium and hot stars, and the formation of emission and reflection nebulae and stars. Based on the analysis of experimental data, mainly photographic observations of nebulae in the Milky Way and extragalactic systems, he made conclusions and suggested well-founded hypotheses on a wide range of considered problems, including those related to cosmogony. The structure of nebulae, and their masses and sizes give reasons behind the conclusion that most of them are formed not in the process of ejection of matter from the stars, but rather they are objects which are born and evolve, and quite often are comprised of giant conglomerates of gas, dust and stars. The distribution of OB-type stars and nebulae in spiral branches points to their genetic relation and the fundamental role of the interstellar medium as the source of their formation. The structural features of nebulae are determined by the action of magnetohydrodynamic forces. Magnetic fields in a galaxy control the motion of diffuse gas-dust matter and ensure the maintenance of its spiral structure. These ideas continue being developed in modern directions of astrophysics.

State of Organic Matter and Particularities of Physicochemical Properties of Soils in the Endogenous Hydrogen Seepage Zones

Open Journal of Soil Science 2018年第8期8卷 186-196页

In the territory of the Voronezh region of Russia in ordinary middle loam chernozem the elevated concentration of endogenous hydrogen streams up to 0.65% at the depth of 100 - 120 cm was detected. This phenomenon is observed in the center of depressions. The soils differ in morphological, chemical and physical properties. The top humus horizon is markedly bleached comparing to the soil outside the depression: The lightness L readings increase for 16% - 30%. The soil acidity (up to pH 4.5 - 5.0) and organic carbon content are elevated comparing to the sample for reference. The proportion of fulvic acids increases on average thrice as compared with the soils outside the hydrogen fluids influence zone. Despite the high humus content the mechanical strength of aggregates decreases 3 - 4 times. Under conditions of hydrogen fluids, changes occur at the aggregate structural level in the direction of decreasing their mechanical strength. In the center of the depressions strength of aggregates is reduced by 2 - 3 times in comparison with the control. The opposite regularity was observed in the absence of hydrogen flows, where the strength of aggregates was 3 times higher than in comparison with the control.

Reduction of serotonergic gene expression in the raphe nuclei of the midbrain under positive fighting experience in male mice

The concept of a major inhibitory role of serotonin in aggressive behavior is widely accepted by investigators. There was ample evidence that a pharmacologically-induced increase in the serotonin activity attenuates agonistic behavior in animals, and that the manipulations inhibiting the brain serotonergic system can elicit aggressiveness in male mice and rats. Repeated experience of aggression in daily agonistic interactions has been shown to reduce serotonin activity in brain of victorious male mice. The study aimed to analyze expression of the serotonergic genes -Tph2, Sert, Maoa and Htr1a, as well as the Bdnf and Creb genes in the midbrain raphe nuclei of male mice with positive fighting experience in daily encounters and male mice with the same track record of aggression followed by two-week no-fight period. It has been shown that mRNA levels of the serotonergic and Creb genes are reduced in the winners in comparison with male mice without consecutive positive fighting experience of aggression. After the fighting deprivation the Tph2, Sert, Bdnf and Creb genes recover their expression while mRNA levels of the Maoa and Htr1a genes proceed at a significantly higher level as compared with the respective controls. Downregulation of serotonergic genes is indicative of the inhibition of serotonergic activity under repeated experience of aggression. Nevertheless recovering of Tph2 and Sert gene expression and overexpression of the Maoa and Htr1a genes after no-fight period suggest that changes in brain serotonergic activity are not main cause of the behavioral pathology developing in male mice in this experimental context.
