Solution of the problem of modeling the local distortions of geometric shape of one-layer domes and its program implementation are presented in the paper. Modeling is based on selection of nodes on the computer screen and assigning the values of initial deviations of selected nodes from the ideal surface along the normal to this surface. The graphical user interface of the program includes the necessary set of instruments and the color palette of visualization for the pattern of distortion.

The algorithm of problem numerical solution for design and calculation of structures, which are interacting with an elastic half-space in terms of flat deformation are presented in the article.

The method thermoactivation current spectroscopy were spent an estimation of chemical activity of antifreezes (degree of aggression of a cooling liquid as solvent in relation to rubber). It is established that chemical activity of antifreeze is connected both with temperature of a cooling liquid, and with a hydrogen indicator of environment.

The characteristic features of using multi-propellant mixed biofuels with rapeseed oil in diesel engines have been considered. The results of experimental research of a type D-245.12S vehicle diesel engine running on diesel fuel, rapeseed oil, rapeseed oil methyl ester and gasoline multi-propellant mixtures have been shown. The dependence of fuel efficiency and exhaust emission characteristics on mixed biofuel components has been shown.

An actual task planning of electric energy consumption on throughput for trunk oil pipeline are considered in this article. Main results of the statistical analysis of characteristics of simulated object, principles and methods of construction of mathematical models were shown. For built models are obtained to assess their adequacy and results verification. The problem is solved by using real data observation one linear plot of trunk oil pipeline.

The problems of the strategic changes in organizations are discussed. The possible variants of resistance to strategic changes are demonstrated. It is noted that the success of the changes depends on how the leadership will implement them. It is paid attention to the fact of the conflict emergence in the process of the changes in the organization.

The paper considers the geological hazard to the example of one of the villages in Gorno Badakhshan Republic of Tajikistan.

The actual problem of preservation of scientific shots of the mining industry is discussed. One of ways of the decision of this point in question at the Russian university of friendship of the people is considered.
