SOCIO-CULTURAL DYNAMICS OF SOCIAL PHENOMENA OF THE RUSSIAN CIVILIZATION

Purpose: Identification of the heuristic significance of radicalism and solidarity as elements of the Russian civilization concept, not only within the framework of a unified, strictly fixed theory, but as universal intellectual tools of a modern socio-humanitarian vision of historical reality. Methodology: The basis of the work is a civilizational approach, which allowed to most effectively evaluate the interesting aspects of the social development of Russian civilization. Main Findings: The authors revealed the specific content of national manifestations of radicalism and solidarity in a philosophical and historical context. The most important manifestations of the social aspirations of key mega-objects of Russian history: the ethnic group, the state and the church are analyzed. When considering the historical specifics of the designated vectors of civilizational dynamics, attention is drawn to the role of individuals in the process of activating or deactivating the indicated directions of Russia development. Novelty/Originality: The authors revealed the specific content of national manifestations of radicalism and solidarity in a philosophical and historical context. The tendency towards radical and solidary forms of interaction among the participants in the civilization process, especially at the tragic moments of historical changes, was a special form of manifestation of social dynamics. Its total completeness, expressed, among other things, through the acceleration or deceleration of the adaptation to historical reality processes, became a state of self-disclosure of specific subjects of social action, acting as vehicles of unknown metahistorical forces

Innovation as the main factor for sustainable development of a commercial bank

The article is an original study of the essence of banking innovations and their role in ensuring sustainable development of a commercial bank. The authors make definitive analysis of the term ‘innovation’ in research works of domestic and foreign authors, reveal their key feature, namely, the novelty that carries energy necessary for sustainable development of economy and a commercial bank. From the point of view of the synergetic approach and using the principles of non-equilibrium thermodynamics, scenario development of an open economic system is considered, a commercial bank being a special case of it; schemes to illustrate it are provided. The analysis made by the authors allows for a conclusion that it is possible to ensure a stable development of a credit institution only if there is a permanent inflow of external energy that compensates for energy losses due to entropic dispersion and a negative influence of internal and external factors thereon. Systemic innovation activity come laden with this energy, which leads to the conclusion that it is innovations that are the main factor ensuring a sustainable development of a commercial bank. A classification of banking innovations into basic (radical), combinatorial, and modifying ones is given.peer-reviewe

Interethnic aggression and extremism in the Rostov Region : forming factors in the conditions of social realities of a multiethnic region

The article is devoted to studying the specifics of the forming factors of interethnic aggression and extremism in a multiethnic region. Based on the results of their own research and the analysis of secondary sociological data, the authors emphasize four primary groups of factors causing the manifestations of interethnic aggression and extremist practices in the Rostov Region: social and economic, sociocultural, geopolitical and the factors connected with the conflictogenic potential of labor migration. It is emphasized that the escalating interethnic tension and aggression in the region have not gained critical character yet; however, under the influence of the pointed factors, the conflictogenic environment is formed, which at occurrence of crisis situations or appearance of radical opinion leaders can provoke an increase in the number of crimes of extremist character. At the end, it is concluded that the urgent need in the minimization of these trends requires carrying out a system policy of the interethnic relations regulation, improving the migrants’ adaptation system and developing a multicultural education system in the region.peer-reviewe

Particularities of spatial kinetics of hybrid thorium reactor installation containing the long neutron source based on magnetic trap

In this work, we study the features of the spatial kinetics of installation as a hybrid thorium reactor with an elongated plasma neutron source based on a magnetic trap. The active zone of the installation under study consists of an assembly of hexagonal fuel blocks of a unified design and a long solenoid with a high-temperature plasma column passing through the axial region of the core. Combining engineering expertise in creating nuclear reactors with a physics-technical potential for obtaining high-temperature plasma in a long magnetic trap we ensure the solution of the multidisciplinary problem posed. These studies are of undoubted practical interest, since they are necessary to substantiate the safety of operation of such hybrid systems. The research results will allow optimizing the active zone of the hybrid system with leveling the resulting offset radial and axial energy release distributions. Results of our study will be the basis for the development of new and improvement of existing methods of criticality control in related systems such as "pulsed neutron source - subcritical fuel assembly"

Influence of a wet wood particle form on the characteristics of its ignition in the high-temperature medium

The results of the experimental and theoretical studies of the processes of the single particles ignition of the wood biomass of various forms (a cube, a cylinder and a sphere) have been presented. According to the results of the experimental studies, it has been established that the particles form can have a fairly significant effect on the characteristics and conditions of ignition. It has been shown that the wood particles in the form of a sphere are ignited much faster than cylindrical and cubic ones (ignition delay times are less by 56%). Such a tendency is maintained for particles sizes from 1 · 10-3?m to 3 · 10-3?m. According to the results of the experiments, the mathematical model for ignition of a particle of wet wood biomass has been formulated, taking into account the joint occurrence of the main processes of the thermal preparation (radiation-convective particle heating, evaporation of water, thermal decomposition of the organic part of the fuel, output, ignition and combustion of gaseous pyrolysis products, ignition of the char residue)
