Natural environment assessment of negative impact of anthropogenic factors

Sustainable development of each region of the country and improvement in living standards and public health can only be achieved by preserving natural capital and maintaining proper environmental quality. Environmental quality in the Krasnodar Region is determined by levels of anthropogenic and technogenic load on the natural environment. Sources of pressure are objects of industry, power engineering, transport, capital construction, agroindustrial complex and municipal services, which lead to pollution of atmospheric air, water and land resources, to pollution of surface and ground water and degradation of some water bodies, to disruption of ecosystems of flora and fauna. The article is devoted to the review of the condition of atmospheric air and water bodies in Krasnodar Krai, as well as to the study of pollution indicators of discharged wastewater in the territory of the region. Information on indicators of polluted wastewater discharge into water bodies is presented, a grouped table is determined on the basis of these pollution indicators, which indicates the main reasons for the continued pollution of surface water bodies, conclusions are drawn as to what measures to solve the global environmental problem should be taken to improve the quality of wastewater treatment

Integrated development of carrying capacities of the Baikal-Amur Mainline and Trans-Siberian Railway

The paper considers actual technical and technological problems in the development of the Eastern polygon of the Russian railway network. The purpose of the study is to develop a methodology and software tools that ensure the search for effective solutions for given resource and logistical constraints. Methods of simulation modeling, distribution of flows on networks and graphs are used. The result of the study is a hybrid set of model calculations

Effect of organic component nature on tribological properties of “bronze-aqueous solution of carboxylic acid-steel” system

The work objective is to study the effect of the alkanoic acids nature on the tribotechnical characteristics of the “bronze-aqueous solution of carboxylic acids-steel” friction system. The tribological tests are carried out on the end-type friction machine AE-5. The sedimentation analysis using the disc centrifuge CPS Disc Centrifuge Model DC24000 is carried out to determine the wear particle size. The surface roughness of the servovite film is determined with the aid of the atomic-force microscope PHYWE. The friction factor fall with increasing the strength of the acetic and glycolic acids, and its growth with the increase of the oxalic acid content in the lubricating medium is observed. When the acid concentration in the lubricant composition and in the oxalic-acetic-glycolic acid series is increasing, the wear factor of the friction couple decreases. With increase in the mean wear particle size in the glycolic-acetic-oxalic acid series, the friction rate increases. The servovite film being formed in the aqueous-glycolic environment on the steel disc surface contains oxygen. The oxygen percentage in the film depends on the specific surface of the nanostructured system
