Family’s World in Mirror of Women’s Press in New Economic Policy’s Period

The transformation of the women’s press during the NEP period is examined in the article, attention is paid to the specifics of the functioning of family and household magazines for women, on the pages of which both the reforms and events of the Soviet era and pre-revolutionary values were reflected. The authors strive to identify the role that the “Magazine for Housewives” and “Women’s Magazine” played during the NEP period, supporting the family world in all its diverse social and spiritual manifestations; to clarify the ratio of traditional and innovative journalistic approaches in the formation of family and everyday media discourse. The results of a quantitative and qualitative content analysis of the publications of the “Magazine for Housewives” and “Women’s Magazine” of the NEP period are presented in the article. The novelty of the research is seen in the analysis of the structural, thematic, functional features of women’s magazines of the NEP era. Special attention is paid to the author’s body, including the previously unexplored works of A. S. Voznesensky (real name — Brodsky), who signed his materials with the pseudonym “Ilya Rentz”. It is concluded that non-state women’s editions of family and household orientation appealed to the experience of pre-revolutionary journalism and, discussing the reform of everyday life and family, continued to write about traditional family values

Rhizobacteria Effect on Arsenic Migration and Translocation of Biogenic Elements in Plants

The study was aimed at the transformation of arsenic compounds in the rhizosphere, its accumulation in plants, P and Si translocation to plants under the influence of Bacillus megaterium var. phosphaticum, and Bacillus mucilaginosus with various forms of As compounds in the soil. The authors describe the maximum effect of Bacillus megaterium var. Phosphaticum strain on As migration, its mobilization and immobilization in the rhizosphere due to arsenic leaching from mineral and difficult-todestroy compounds and its accumulation in plants. The forms of arsenic compounds were isolated from the rhizosphere based on sequential extraction procedures. The features of the inter-element As-P interaction in plants were established. With the intense accumulation of As in the rhizosphere inoculated with rhizobacteria, the intake of phosphorus into plants was not observed, as contrary to Si. The study of As and biogenic elements behavior under the influence of rhizobacteria is of great importance in the development of ecobiotechnologies related to soil remediation and crop production

Academic Motivation of Elementary School Children in Two Educational Approaches — Innovative and Traditional

Background. While the current literature provides valuable insight into how school climate perceptions and student motivation impact academic achievement, research examining the mediating efects of motivation in the linking of an innovative educational system, school climate, and achievement is limited. Tis study considers the potential of the El’konin–Davydov system of developmental education as a basis for educational innovation. Self-determination theory is applied as a useful theoretical framework that allows for consideration of both the intensity and the quality of academic motivation. Objective. Te study examines a model that illustrates the role of intrinsic and different types of extrinsic motivation in linking the El’konin–Davydov system of developmental education (DE) and school climate to the academic achievement of elementary schoolchildren. Design. Participants were 345 third and fourth graders drawn from four public schools in Moscow, with some (N = 192, 2 schools) educated in the traditional system and others (N = 153, 2 schools) in one that follows the DE system. A cross-sectional design was implemented. Results. Students in the DE system showed signifcantly lower external motivation for all three subscales (Parents, Teachers, General) and perceived school climate more favorably. Structural equation modeling showed that the hypothesized model ft the data well, supporting the hypothesis that student external motivation plays a mediating role in linking educational system (innovative vs. traditional) with academic achievement. Students’ autonomous motivation was shown to play a mediating role in linking positive perceptions of school climate with academic achievement. Conclusion. Te elementary school students from developmental education classes compared to their peers from traditional education classes demonstrate more positive profle of academic motivation including lower external motivation, more positive attitude towards school and study; however, the two groups do not difer in the level of intrinsic, identifed, and introjected motivations

Record electron self-cooling in cold-electron bolometers with a hybrid superconductor-ferromagnetic nanoabsorber and traps

The Cosmic Microwave Background (CMB) radiation is the only observable that allows studying the earliest stage of the Universe. Radioastronomy instruments for CMB investigation require low working temperatures around 100 mK to get the necessary sensitivity. On-chip electron cooling of receivers is a pathway for future space missions due to problems of dilution fridges at low gravity. Here, we demonstrate experimentally that in a Cold-Electron Bolometer (CEB) a theoretical limit of electron cooling down to 65 mK from phonon temperature of 300 mK can be reached. It is possible due to effective withdrawing of hot electrons from the tunnel barrier by double stock, special traps and suppression of Andreev Joule heating in hybrid Al/Fe normal nanoabsorber

Molecular structure and properties of κ-carrageenan-gelatin gels

© 2018 Elsevier Ltd Rheological studies, FTIR spectroscopy and a molecular docking approach were used to explore the structural basis of the peculiar physicochemical properties of gelatin gels modified with a κ-carrageenan admixture. Mixed gel properties are affected by the polysaccharide-to-gelatin ratio, Z, and can be divided into two categories. At low ratios, the strength of mixed gels varies insignificantly compared to gelatin due to the similar structures of the gels. Above the threshold content of κ-carrageenan (Z > 0.1), the storage modulus and yield stress of mixed gels are significantly enhanced. The nonadditivity and threshold character of the rheological properties could be the result of conformational ordering of both gelatin and κ-carrageenan, leading to the formation of additional junction zones in the gel network. According to molecular docking studies, the junctions could be formed as a result of complementary interactions between the gelatin triple helix and the κ-carrageenan double helix. The stack formation increases the interaction energy, which explains the strengthening of the gel network

Evaluation of wheat products with high flavonoid content: justification of importance of marker-assisted development and production of flavonoid-rich wheat cultivars

In the structure of the global commodity supply in the food market in modern conditions it is necessary to note the emergence of a broad group of new high-tech products, and specialized functional food with high value added. The creation of varieties with a high content of flavonoids (plant compounds that can have a positive effect on human health) is one of the important directions of plant breeding oriented on the functional foods development. Currently, however, there is a significant gap between the well-studied role of flavonoids and the genetic control of their synthesis, on the one hand, and development of the actual product of wheat with new properties, evaluation of the nutritional value of the end-use bakery products for consumption, on the other hand. In the present study we produced and investigated bakery products from wheat synthesizing bioflavonoid pigments anthocyanins in the grain pericarp. The grains of this wheat have dark purple color. Red-grained bread wheat was a control. These two wheat lines have almost similar genomes with the exception of a small part of chromosome 2A, which contains the Pp3/TaMyc1 gene regulating anthocyanin biosynthesis. The use of such an accurate model has allowed relating the observed differences precisely with anthocyanin biosynthesis. The important task was to evaluate the resistance of anthocyanins to the backing process. Therefore anthocyanin content was evaluated not only in the end-use product, but also in mixtures of flour and bran used for baking and separately in the bran. As a result, significant differences were detected in samples obtained from purple grains, compared with the control including the products that had passed a full processing cycle, including baking at elevated temperature. For the extraction of anthocyanins conditions were simulated most similar to those in the process of digestion in the stomach, in order to assess the amount of assimilable anthocyanins. By our estimates one can get up to 1.03 mg of assimilable anthocyanins with 100 g of whole-grained bread produced from anthocyanincolored grains. With 100 g of bran, the body will get up to 3.32 g of anthocyanins. In parallel with the evaluation of the anthocyanins content in all samples, the mass fraction of antioxidants was measured by using the amperometric method. The highest antioxidant capacity was shown for bran, while the least one was demonstrated for flour. Adding bran to the flour as well as the backing process increased the antioxidant capacity of wheat products. The contribution of anthocyanins to increased antioxidant capacity is not significant. It was shown that bread-making quality and organoleptic properties of bakery products made from anthocyanin-colored grains did not concede, or in some cases were higher than the corresponding properties of products obtained from control NIL grains. It was found that the presence of anthocyanin increases the shelf life of bakery products and their resistance to molding in provocative conditions. These results, combined with the known data about the beneficial health effects of anthocyanins, suggest that wheat bakery products made from anthocyanin-rich grains can be included to the list for dietary food. Marker-assisted selection accelerating the creation of new forms of crops with a high level of flavonoids can be proposed as a new direction for the expansion of domestic and export grain market potential due to the new possibilities of obtaining products of increased nutritional value and making a good profit
