Authors: Panteleeva M , Borozdina S 
Published: April 2020

Abstract
The article is devoted to the analysis of possible solutions to traffic congestion, which have become an integral part of the modern space of the cities and regions population vital activity, especially near houses and shopping complexes. It is impossible to characterize the modern transport system without mentioning errors when planning the organization of traffic, as well as in the design and construction of transport hubs. Attempts to solve the problem of traffic congestion have been made repeatedly in various countries of the world, but all of them were of a differentiated nature and national specificity. Many researchers believe that in order to level transport problems, it is necessary to build new road junctions and separate traffic flows. However, according to the authors, the most suitable, in particular, for our country, can be a comprehensive approach to solving these problems. This approach involves the creation of a parametric model of forming an indicators system for assessing the operational state of road interchanges in the living environment formation conditions. This system allows taking into account the integral impact of technological, economic, environmental and social factors that affect the efficiency of transport interchanges.

Published: April 2020

Abstract
Approach to choose a place for the incinerator plant is considered in the paper. One of the ways to solve the problem of continuous growth of household and industrial waste in the world is construction of incinerators. In Russia, there is still a great fear that the incineration of waste will dramatically worsen the environmental situation. It is significant to take into consideration the cost of construction, the necessary conditions for construction and the opinion of citizens when choosing the appropriate location of the plant. Since this problem is multi-criterion, the method of hierarchy analysis was suggested to consider the site selection. This approach refers to the problem of decision-making in conditions of certainty, but in a situation when the quantitative indicators are determined on the basis of the scale of preferences and on the basis of feelings and emotions. The stages of solving problem with the help described method are described. The hierarchy analysis technique was demonstrated by the example of the task to find a place for the location of the waste incineration plant

Published: April 2020

Abstract
The article presents the results of modeling the operating parameters of an engine pressurization assembly centrifugal compressor at evaporative air cooling. A step-by-step method for calculating a centrifugal compressor is described in order to evaluate the effect of evaporative cooling and air humidity on the temperature behind a centrifugal compressor. The proposed method for calculating the operating parameters of an engine pressurization assembly centrifugal compressor of an internal combustion engine with evaporative air cooling is used to evaluate the effect of humidity on the operation of a turbo compressor using an author program (certificate of state registration of the computer program № 2016611761). A series of calculations of a centrifugal compressor parameters was carried out with finely dispersed water in front of the compressor, which allowed the air humidity to be maintained at 100% with changes in temperature and pressure during the compression process. Analysis of the results showed areas in which it is advisable to organize the separation and removal of excess moisture. The presented research results are necessary for choosing the methods for separating moisture during evaporative cooling of charge air in turbocharged internal combustion engines.

Authors: Gabitov A I 
Published: April 2020

Abstract
Theoretical concepts of inhibition mechanism in metal corrosion and forecasting of protective properties of substances are connected with experimental (electrochemical, adsorption, mechano-chemical) research. Inhibition mechanism may be fully demonstrated by comparing experimental research data with results of calculating quantum-chemical values of the proposed corrosion inhibitors molecules. The latter therewith enable to detect those physico-chemical characteristics that directly demonstrate protective properties of the inhibitor. Molecular moment, number of atoms in molecule and number of electrons in outer molecular orbitals are found to have maximum affect on the protection level. Application of petrochemical products including semi-finished products and petrochemical wastes for making new highly efficient and relatively inexpensive corrosion inhibitors is shown to be promising. Calculation results of quantum chemical values of corrosion inhibitors molecules by heterocyclic compounds may be used in learning corrosion inhibition mechanism by the compounds studied.

Authors: Melnikov A E , Grib N N , Rochev V F 
Published: April 2020

Abstract
The paper presents some results of comparative tests for the strength properties of enclosing rocks from the coal deposits of Southern Yakutia. For example, the ultimate compressive strength of fine-grained sandstones from the Chulmakansky coal deposit was determined in two ways. In the former case, the authors determined maximum collapse pressure for cylindrical samples. In the latter case, arbitrary-shaped samples were tested by loading a sample with opposing indenters of conical shape. As a result, it was established that the difference in rock strength characteristics determined in the above-mentioned ways, does not exceed 20%. When determining rock strength by loading arbitrary-shaped samples with opposing indenters of conical shape, overestimated values are obtained as compared to the classical test. Nevertheless, point load method can be used in order to promptly determine the strength characteristics of sandstone in the course of mining operations provided the number of test samples in a series is increased.
