Working Out of Resource-Saving Technology of Enrichment of Phosphate-Raremetall Ores

Possibility of complex use of phosphate-raremetall ores of the Tatar deposit is proved. Results of researches of crystal-chemical features of the minerals which are a part of rejects of electric separation of ore-dressing plant of the Tatar deposit ores on which basis perspective reagents are chosen are stated. Law of action of the chosen reagents on minerals of electric separation rejects is established. On the reagents which have given the best indicators of flotation on monofractions, researches on rejects of factory with use of the multilevel factorial plan 33⁄9 are conducted. It is received an apatite concentrate with the maintenance of Р2О5 39,9 % at extraction of 98,5 %.Доказывается возможность комплексного использования фосфатно-редкометалльных руд Татарского месторождения. Изложены результаты исследований кристаллохимических особенностей минералов, входящих в состав хвостов электрической сепарации обогатительной фабрики руд Татарского месторождения, на основе которых выбраны перспективные реагенты. Установлена закономерность действия выбранных реагентов на минералы хвостов электрической сепарации. На реагентах, давших лучшие показатели флотации на монофракциях, проведены исследования на хвостах фабрики с использованием многоуровневого факторного плана 33/9.

Adaptation of Fire-Fighting Systems to Localization of Fires in the Premises: Review

Fire protection is a basic safety issue for all categories of buildings. The criteria for effective fire suppression and the characteristics of extinguishing systems in insulated areas depend on a combination of factors. The main influences include the type of combustible material, ambient temperature, type of spray extinguisher, air inflow and outflow conditions, and space geometry. This article analyzes the most widely used fire-extinguishing technologies in different locations. The main aspects of using the pulsed delivery technology of extinguishing liquid are considered. Based on the analysis of publications from the last decade, it is possible to develop intelligent systems for recording fires and extinguishing fires in the premises

Basic Directions of Wage Differentiation in Industry

The most important tasks noted at the Twenty-sixth Congress of the CPSU include the further improvement of the organization of wages, in the course of which it is necessary to see to it that they correspond entirely to the worker's contribution to the nation's work effort. "Life," M. A. Suslov noted in his speech at the All-Union Conference of Social Science Department Heads, "requires raising the stimulating role of wages. And this requires that we strive for a direct dependence between the size of wages and the actual results of labor always and everywhere."

Monetary incentives as a management technique in the system of public sector in the states with market economy

The paper analyzes experience of nations with well-developed market economy in terms of monetary incentives of public sector employees as a state technique of efficient management of public sector. Principles and techniques of wages setting up are considered as well as social payments to employees of the sector, differentiation of wages of employees of various levels of authorities and budget sponsored agencies

FEATURES OF MICROHAEMODYNAMICS AND ENDOTHELIUM-DEPENDENT DILATION OF MICROVESSELS AT DIFFERENT TYPES OF REGULATION OF BLOOD CIRCULATION

Microhaemodynamics research at practically healthy persons with hypo-, eu- or hyperkinetic type of regulation of blood circulation is conducted. Absence at them in a condition of functional rest of distinctions in the values of linear and volume speed of a blood-groove in the nail roller of a finger of a brush is shown. In turn, the analysis of reactivity of microvessels at test with a shoulder occlusion, allowed to establish that for hypokinetic type of regulation of blood circulation, unlike two other types, decrease in an endothelium-dependent vasodilatation is characteristic
