THE TENDENCY OF DEVELOPMENT OF RUSSIA: FROM COLLECTIVISM TO INDIVIDUALISM

P. A. SOLKINA
Krasnoyarsk
Keywords: the Western society, individualism, equality, freedom, Russia

Abstract >>
This article presents a social-philosophical analysis of the tendency of development of Russia. The division of the society into types has a centuries-old history. Any concept of management of the society assumes a certain specificity of the corresponding society’s sociality, in view of which the managerial process is presented as appropriate to the life of the society. Historically, Russia has found its realization in the collectivist forms of life of the Russian people, which provides the system’s integrity and stability of the Russian society. On the contrary, the Western societies live according to the individual sociality, and its basic standards are equality and freedom. The transition from one type of a society to another type is a fatal step in the development of this society; it is a reassessment of values, change of the lifestyle and mentality.

Keywords: minerals, sulfhydryl collectors, flotation, atomic charges, collector activity, molecular modeling

Abstract >>
The authors carried out molecular modeling of clusters of simple structure and ring structure pyrite. It is suggested to analyze bonding of a collecting agent and cluster atom using the collector capacity forecasting index. It is shown that butyl dixanthate more vigorously connects to cluster atoms than thionocarbamates, e.g., Z 200 and IETNC. Analysis of the charge transfer in interaction of pyrite and the listed collecting agents shows that in monodentate bonding the charge is transferred from the mineral to the collector sulfur atoms and in bidentate bonding the classical transfer of the charge from the collector donor to the mineral acceptor is observed. It is supposed that ferrum xanthate decompounding in an acid medium results in inception of dixanthates that govern pyrite flotation. Pyrite oxidation and elemental sulfur formation also favor pyrite flotation and complicate pyrite depression in an alkaline medium.
