It is shown that intermetallic metals of the modifying ligatures are not the crystallization centers of primary crystals of a a-phase. As the main demodifier serves hydrogen dissolved in liquid silumin. For a solution of the problem of modifying of primary crystals of a a-phase in castings from silumins it is necessary to accept a presumption that crystallization centers of primary crystals of a a-phase are the crystalline developments consisting of a-phase nanocrystals, and the role of the modifying intermetallic metals of modifiers comes down to the active absorption of the dissolved hydrogen.

It is shown that the phosphorum which is contained in a silumin melt in number of 0,01–0,04% exists in the dissolved form. For a solution of the problem of modifying of primary crystals of a β -phase in silumin castings it is necessary to accept a presumption that the oxygen adsorbed by a melt promotes decay and hinders the formation of crystallization centers of primary crystals of a β -phase. The role of phosphorum comes down to reduction of concentration of the adsorbed oxygen which works as the demodifier of primary microstructure of castings.

The Mind

The problem of the “wandering mind” phenomenon is considered in an interdisciplinary perspective. We provide evidence that the “wandering mind” is the cause of attention errors when performing cognitive tasks, both in laboratory conditions and in professional and daily activities. We show the role of “wandering mind” in the modeling of personal psychological future. According D. Kahneman’s conceptual views on the thinking nature, the “wandering mind” is a prerequisite of appearance of creative ways to solve ambiguous problems (“creative insight”) in the process of thinking. Based on the B.F. Lomov’s methodological conception, we reveal the need for considering the problem of “wandering mind” along with socio-psychological characteristics of a group (such as, for example, incorporativity), which includes subjects that are in the described condition.

We consider the formation and development features of the nurseries as a special social institution in the Tambov Governorate in the early of 20th century. The governorate and county levels of declared scientific problem consideration allows to conduct the successful reconstruction of the formation and activities of infant nurseries for foundlings, orphans in both urban and rural areas, which reflected the practice of social care and charity of “trouble children”. We reveal the implementation features of county initiatives for the social protection of foundlings and orphans, as well as the levels and forms of such support for such categories of Russian society by local authorities. We clarify the possibilities of organizing nurseries for foundlings at the governorate and county hospitals and maternity wards. We note the role of particular medical workers in the development of civic initiatives and public service in the rescue of foundlings. We identify the historiographic traditions of both domestic and foreign historians in the study of the orphans charity in the context of the social work organization and the social institutions development, including nurseries. Based on the analysis of a wide range of historical sources, it was possible to identify the most successful and effective practices of organizing nurseries both in the peaceful years and in the periods of Russian-Japanese War of 1904–1905 and World War I 1914–1918, which allowed us to consider various little-studied aspects of the stated scientific problem. We reveal the regional features of the social protection system for orphans through the prism of nursery care. We clarify the position and role of the Orthodox Church on the organization of orphan charity in monasteries during the war years of 1914–1918. We reveal the main posing issues of the prospects for studying a wide range of problems in the history of orphanhood in the Tambov Governorate in the early 20th century. We pay attention to the importance of taking into account regional specifics and specific historical manifestations of social policy when conducting a study of charitable support and private public initiatives of the considered period.

The form, typology, essence and causes of the interaction between theater and cinema in the world is one of the priorities in the field, and a number of scientific studies have been conducted on the subject. In world experience, during the development of cinematography, it has been used the help of theatrical figures in overcoming the problems of acting, directing and dramaturgy. The study of theater and cinema as the main types of artistic worldview, in which the relationship between the two independent arts, exchanges of actors, process of interaction, individual characteristics were assessed, and it was considered as a new phenomenon. The article studies issues, causes and factors of influence of the same process in 1920–1930. The interaction of Uzbek theater and cinema, the study of creative ties, see it as a scientific problem has attracted attention in recent years. The article examines the role of Uzbek stage leaders in the development of screen art as a separate process, as well as the phenomenon of interaction between theater and cinema. The author explores a new creative life, a biography of a stage actor in cinema, opened for theater actors on the eve of the twentieth century. The art of filmmaking, which has been fighting for the actor for half a century, studies on facts that have attracted theater performers. Theatrical art has proven to be a model for cinematography in terms of decorating, makeup, music, lighting, and acting.

This article is dedicated to examination of the role of Parliamentary Assembly in development of the Union State. The goal is to trace the parliamentary activity in the Union State throughout the entire time of its existence, the objectives that were pursued, their transformation, and change of conditions for their accomplishment. This topic is especially relevant in the current context. A new milestone has passed in the history of Union State: December 2019 marked twenty years since its creation. Agreement on the formation of Parliamentary Assembly of the Community of Belarus-Russia Union State was signed earlier, in 1996. The novelty of this works consists in comprehensive and detailed analysis of different stages in formation of Parliamentary Assembly, which allows describing their role in further consolidation of the Union State. The scientific problem of this article can be articulated as follows: Parliamentary Assembly is not just a legislative institution that formulates the agenda for development of the Union State; it is also a platform for a continuous dialogue between Russia and Belarus. Therefore, examination of this government institution in an urgent scientific problem that allows revealing the key aspects of evolution of the Union State. As the resources for this article, the author explored the legislative acts of the Republic of Belarus and the Russian Federation, legal information from official portals of the Union State and the Parliamentary Assembly. This underline the need for further development of parliamentarism in Russia-Belarus Union State for the purpose of improvement and strengthening of relations between the countries in the current conditions of international transformation. The article is based on most relevant documents pertaining to Russia-Belarus relations for the period from 1991 to the present.

Strong steels suffer from embrittlement due to dissolved hydrogen, a phenomenon which can be mitigated by trapping the hydrogen at carbide particles, where it is rendered benign. The precipitation and coarsening of plate-like M 4 C 3 carbides, during the tempering of quaternary Fe–C–Mo–V martensitic steels, has been characterized both experimentally and by developing appropriate kinetic theory. The trapping capacity is found to peak when the carbides are about 10 nm in length, indicating a role of coherency strains in trapping hydrogen atoms via elastic interactions. This suggests a method for developing alloys which are better able to resist the detrimental effects of hydrogen.

For a solution of the problem of modification of a microstructure of cast alloys it is necessary to accept admission that crystallization centers of crystals of phases are the crystalline buildups consisting of nanocrystals of phases. The role of modifiers comes down to lower concentration in a metal melt of the dissolved surface-active elements and gases and (or) to formate of the moistened substrates on which process of gas generation and deleting gas bubbles will be most preferable.
