Theoretical and experimental study of high-pressure synthesized B20-type compounds Mn1−x_{1-x}(Co,Rh)x_xGe

The search and exploration of new materials not found in nature is one of modern trends in pure and applied chemistry. In the present work, we report on experimental and \textit{ab initio} density-functional study of the high-pressure-synthesized series of compounds Mn$_{1-x}$(Co,Rh)$_x$Ge. These high-pressure phases remain metastable at normal conditions, therewith they preserve their inherent noncentrosymmetric B20-type structure and chiral magnetism. Of particular interest in these two isovalent systems is the comparative analysis of the effect of $3d$ (Co) and $4d$ (Rh) substitution for Mn, since the $3d$ orbitals are characterized by higher localization and electron interaction than the $4d$ orbitals. The behavior of Mn$_{1-x}$(Co,Rh)$_x$Ge systems is traced as the concentration changes in the range $0 \leq x \leq 1$. We applied a sensitive experimental and theoretical technique which allowed to refine the shape of the temperature dependencies of magnetic susceptibility $\chi(T)$ and thereby provide a new and detailed magnetic phase diagram of Mn$_{1-x}$Co$_x$Ge. It is shown that both systems exhibit a helical magnetic ordering that very strongly depends on the composition $x$. However, the phase diagram of Mn$_{1-x}$Co$_x$Ge differs from that of Mn$_{1-x}$Rh$_x$Ge in that it is characterized by coexistence of two helices in particular regions of concentrations and temperatures.Comment: 12 pages, 11 figure

Sociology, labour and transition in post-Soviet Russia: A view from within

For almost 20 years, since the early 1990s, Professor Simon Clarke led multiple international research projects in Russia, China and Vietnam studying labour relations, enterprise restructuring and household economics under post-socialist transition. Breaking out of post-socialist scholarship’s narrow confines, both social and ideological, he led an exploration of the void opened by former Soviet Union disintegration reconnecting with those who brought the brunt of it. Equally unique among western scholars was his promotion of a vast network of former Soviet Union researchers and activists, later formalised in the Institute for Comparative Research in Labour Relations. Here, for the first time, some of its leading scholars reflect on his legacy, methods and ever-lasting contribution to the advancement of sociology and social activism in Russia. Their accounts convey the radically alternative character of the overall project, returning both achievements and limitations. In substantive terms, the emerging picture confirms the indeterminacy and complexity of Clarke’s original findings: no linear development from ‘the subsumption of labour under capital’ to ‘familiar patterns of class conflict’ has occurred. Instead, growing labour protests follow labour degradation and restructuring, a strong state becoming the arbiter in the stand-off between neoliberalism and workers’ resistance

Electrical discharges in the atmosphere of Venus

Data received from Venera 11 and 12 experiments involving the electrical activity of the atmosphere of Venus show that the electrical discharges occur in the cloud layer. Their energy is roughly the same as in terrestrial lightning, but with a pulse repetition frequency of the discharges which is much greater

Continuous adult education for social and occupational mobility: innovative educational resource of Borovichi teacher training college

This article represents innovative educational resources that allows teachers to create organizational practice and didactic conditions for the implementation of continuous multilevel formation of various categories of studentsПредставлены инновационные образовательные ресурсы, позволяющие преподавателям Боровичского педагогического колледжа на практике создавать организационно-дидактические условия для реализации непрерывного многоуровневого образования различных категорий обучающихс

In vitro clonal micropropagation of Aronia L. varieties from the collection of the botanic garden of the National Research University “BelSU” (Belgorod, Russia)

Studying the characteristics of in vitro cultivation of species and varieties of Aronia made it possible to determine the optimal conditions for sterilizing plants, the composition of the medium for propagation and rhizogenesis of explants. Adaptation plant varieties of Aronia obtained using the developed media and cultivation regimes is characterized by a high survival rate (97-99%) under unsterile conditions, which makes them potential objects for mass replication by clonal micropropagatio

The main features of phraseological units in the Russian and Armenian languages and their translation

The study deals with the structure of phraseological units of the Russian and Armenian languages. The researchers analyze figurative meaning of phraseological units appearing on the base of primary, nominative meaning of the words in one or another free phras

Elastic properties of FeSi

Measurements of the sound velocities in a single crystal of FeSi were performed in the temperature range 4-300 K. Elastic constants $C_{12}$ and $C_{44}$ deviate from a quasiharmonic behavior at high temperature; whereas, $C_{12}$ increases anomalously in the entire range of temperature, indicating a change in the electron structure of this materia

Online education in sociology and history: causes and consequences of deficit in Runet

Недостаточно развитый рынок онлайн-образования в России включает МООС и другие образовательные ресурсы по социологии и истории, однако их количество явно мало с учетом мировоззренческой функции социологии и истории. История активнее представлена на русскоязычных образовательных платформах. У социологии есть специализированная – ФОМлабс. Чем больше российских граждан будут учиться в интернете истории и социологии, тем выше будет сформирован уровень критического мышления, гражданской культуры.Underdeveloped market of online education in Russia includes MOOC and other educational resources on sociology and history, but, considering the ideological function of sociology and history, the number of them is very small. History is represented more by the Russian educational platforms. Sociologists have a specialized one – FOMlabs. The more Russian citizens learn history and sociology on the internet, the more the level of critical thinking and civic culture increases

THE MISSION OF THE REGIONAL UNIVERSITY AND ITS FOCUS ON THE DEVELOPMENT OF HUMAN CAPITAL IN THE REGION

The purpose of the article: The article clarifies and justifies the mission of a modern regional university, which focuses on the activities of a university on the development of human capital in the region.Materials and methods: Based on the data of scientific literature, strategic documents of the state, materials of regional statistics, surveys of respondents, the strategic direction of the formation of a regional university is justified - orientation of its mission, research and educational activities on the development of human capital. A range of directions for improving the functioning of a regional university has been proposed and justified in order to bring the content of its activities in line with the regional focus and the new mission.Results of the research: Regional universities are presented in the article as high-tech educational organizations of higher education, the vector of strategic development of which should be focused on maximum integration into the economy and social sphere of the regions. Structural components of human capital are proposed - education capital, health capital, labor, cultural and moral capital, intellectual capital, entrepreneurial capital, social capital, cyclically interacting with each other in the process of personal and professional development of a teacher.
