The state of the atmospheric air in such industrial cities of the Rostov region, as Belaya Kalitva, Donetsk, Kamensk-Shakhtinsky over the last 10 years (2003-2012). Identified main pollution sources and priority pollutants. Analysis of the concentrations of pollutants in areas of concentration of industrial enterprises, on highways and in dwelling zones. It is established that industrial cities are specific «geochemical provinces», in which abnormally elevated concentrations of many chemical elements. On the background of the decrease of the role of industrial enterprises in the air pollution increases the role of motor transport

The summary. In article, with the account of generalisation of references, questions of essence and methodology of an estimation of economic efficiency of manufacture are considered. On materials of subjects of the Russian Federation the estimation technique potential of territories is developed and realised (with the account occupied in economy, fixed capital, investments into fixed capital, innovative possibilities), the estimation, from positions of measurement of productivity of live and last work, efficiency of functioning of regional economy is carried out.

Keywords: Keywords: an estimation, efficiency, productivity, potential, region, innovative possibilities.

It is presented in article that the technique of determination of stochastic similarity of functioning of one of subsystems of the intensified hydrothermal treatment - moistening of details of top of footwear. According to the offered technique there were received to be expressions for determination of output parameter of process "moistening" - the module of elasticity of skin and relative deviations of characteristics the subsystems proving similarity functioning of considered subsystems in stochastic sense. According to the offered technique expressions for determination of output parameter of a subsystem of "moistening" - the module of elasticity of skin and relative deviations of independent parameters of process of the vacuum and sorption moistening, providing with the possibility of forecasting of the minimum duration of processing were received.

Keywords: stochastic similarity, means-equipment-technology-production system, the processing intensified hydrothermal treatment, the vacuum and sorption moistening, the determined similarity, tanning and shoe materials

  To estimate the effectiveness of forest machines developed technological possibility coefficient. Coefficients reflect the ability to provide a given performance of transport vehicles in the logging, the decline in the quality of the skid road surface. Method allows determining the amount of logging residues, necessary for the skid road construction. At calculating the available volume accounted for logging residues. Resources of logging residues are calculated depending on the type of timber and the length of skid road. The method allows selecting the optimum system of machines to work in these natural production conditions or schedule performance loss due to reduced carrying capacity of skid road.
