  • Socio-economic and environmental conditions improve the waste management system of production and consumption

    The modern world is experiencing a new period of development, which in its essence and significance surpasses the previous stages of the evolution of society. We are talking about changes in all spheres of human activity, including in the interaction between society and nature. Modern trends in socio-economic development of society aimed at ensuring sustainable production and environmental safety in the application of various manufacturing and processing technologies. It is especially important to create conditions in the disposal of industrial and household waste, as the use of secondary resources will reduce the deficit of natural resources due to its depletion. And to ensure the functioning of the economic conditions and prospects for the development of such technologies and their effects on the environment will help to research and development of appropriate economic instruments. Rate the degree of approximation to the level of the production system is extremely effective technology in terms of environmental impacts can use environmental monitoring her condition, which can be carried out in various areas, the relevant objects of research. It is thus possible to monitor the dynamics of the processes of development of systems to give an adequate idea of ​​the most significant economic and environmental consequences of the practical implementation of the proposed construction and installation work.

  • The main defects of case details of cars and ways of their elimination applied in car repair production

    Production of case details – the difficult technological process demanding providing with the expensive specialized equipment, high-precision gages and defining a product level of quality. In this regard, the nomenclature of new qualitative case details in the market is very limited. In designs of cars case details are present practically at any knot or the unit. For example, the case of a transmission, transfer case (at its existence) the block of DVS cylinders, cases of the main thing and wheel reducers, cases of hydraulic and pneumatic pumps, cases of distributing devices, brake cylinders and so on. In article the concept of a case detail is considered, influence of quality of production and technical condition of case details on providing a resource of cars is revealed. Main types of influences which influence case details in use of cars are listed. Classification of the main defects of case details of cars is given, and the most perspective ways of their elimination in car repair production are considered. The listed ways found rather broad application in car repair production, but with growth of scientifically technical progress, emergence of new materials and technologies need improvement and modernization.

  • Employment of the population as factor of economic development of the territory

    One of the main priority objectives of economic policy of the government of any country in the long term is stimulation of economic growth. Has labor productivity direct impact on rates of economic growth both in the country in general, and in separate branches of economy. Employment can be referred to one of important factors of growth of labor productivity undoubtedly. In article the problem of employment of the population as one of factors of growth of labor productivity and its influence on the economic growth of the territory is considered. The correlation and regression analysis between indicators of unemployment rate and gross domestic product (GDP) is carried out. As a result of the analysis of coefficient of linear pair correlation we come to a conclusion that, according to Cheddok's scale, qualitatively communication force between factors can be characterized as "moderate", that is in 28,64% change of unemployment leads to change of GDP. If to analyze coefficient of linear pair correlation, we can come to a conclusion that communication between factors the return, that is at decrease in unemployment is observed GDP growth and vice versa. Thus, labor productivity, one of which factors is employment of the population, is the most important indicator of development of economy of the territory.

    Keywords: Employment of the population, economic development of the territory, labor productivity, correlation and regression analysis.

  • Efficiency Estimation of water -soluble technological lubricants at diamond - abrasive treatment by friction machine СМЦ-2

    The main trends of updated automobile construction are the use of permanent for lowering mass overall dimension characteristics of electric equipment and an automobile as a whole. Diamond-abrasive treatment of sintered powder permanent magnets on the basis of Barium ferrite, strontium and cobalt is connected with difficulties of obtaining surfaces with little meanings of rouhness due to the higher brittleness, tendecy to crack formation, water-soluble technological lubricants (FWSTL) РВ-6 have been developed which contain fractal clusters and generate in contact diamond-abrasive tooltreated powder magnetic material of films with high load and lubricating abilities. Estimation criteria of water-soluble lubricacants efficiency (WSTL) at diamond-abrasive treatment by friction machine СМЦ-2 have been suggested.
