Safety of urban buildings near explosive objects
Authors: Bazhina Elena , Bazhin Pavel 
Published: July 2020

Abstract
The article outlines the basic principles for choosing the most rational urban development near explosive urban facilities. The developed principles make it possible to minimize risks both for newly constructed and for constructed urban facilities located near energy-intensive industries.
The following points must first be made. There are several possible options that are pursued in determining the security status of objects, people and territories adjacent to explosive objects. Firstly, it can be preliminary calculations for assessing safety zones, and secondly, the purpose of research can be to determine the degree of safety of a particular object located near the alleged source of an emergency explosion. For example, an oil refinery, which is energy-intensive and occupies a significant territory through which mechanisms and people move and on which industrial and auxiliary buildings are located.
Let us turn to the methodology for calculating the dynamic characteristics at a certain point in the air medium disturbed by the explosion.
The technique used is a difference analogue of the laws of conservation of mass and momentum. In this case, the entire computational domain is preliminarily divided into a certain number of computational cells in which the calculation of the parameters of the medium is carried out. The method used to calculate the parameters characterizing the interaction of compression waves with buildings and structures is based on a numerical scheme. Its essence is reduced to direct numerical integration of conservation laws in a differential form with the use of integral conservation laws. This method is known as the Godunov method and is used to solve non-stationary problems of hydrodynamics.
The results of the calculation of the effect of compression waves on buildings during a deflagration emergency explosion at a nearby energy-consuming facility – fuel filling station (AZS) are considered.

Authors: Shishelova T I , Fedchishin V V , Hromovskih M A 
Published: July 2020

Abstract
Production of electric power by nuclear power plants (NPP) in the world and in Russia accounts for about 17%. Much attention is currently paid to safe NPP operation and to enhancement of their reliability. Present-day nuclear power plants with high-temperature gas-cooled rectors require development and application of new composite materials capable to withstand high temperatures and mechanical stresses. Ceramic composite materials where whiskers of heat-resistant chemical compounds are used as reinforcement fibers look promising for those purposes. The paper investigates and analyses the opportunity of applying whiskers as reinforcement fibers for heat-resistant composite ceramic building materials. Studies revealed that whiskers of silicon carbide and aluminium nitride are resistant towards high temperature heating without notable change in their chemical composition. It was found out that mono crystals of silicon carbide have higher mechanical strength owing to lack of defects in its structure. Linear heat expansion factors of silicon carbide that are needed for thermo-chemical calculations of composite materials on its base were determined.

Abstract
Experimental studies on the decontamination and stabilization of sludge were carried out using the product “Desolak”, which is calcium oxide treated with a disinfectant. As a result of the research, it was found that the sewage sludge of Voronezh is safe and can be used as organic fertilizer for growing agricultural plants. The determination of the content of mineral nutrients in the soil and the soil reaction showed that the application of organic fertilizers in the form of sludge in comparison to the variant without fertilizers increases the content of nitrogen nitrate, exchange potassium, and mobile phosphorus in the soil. At the same time, the mass fraction of impurities of toxic elements in the soil decreases when sewage sludge is added as an organic-lime fertilizer.

Authors: Uvarova O A , Naumova O E 
Published: July 2020

Abstract
The article discusses the formation experience of the fuel and energy complex of Eastern Siberia. Based on the analysis of a large number of archival materials, it is shown how enterprises of oil and gas production, coal industry, and hydropower were built under the conditions of the controlled and planned economy. The geography of Eastern Siberia contemplated the construction of powerful industries, which became natural monopolies under the new economic conditions. The coal industry was mostly privatized. Today, the enterprises producing and processing oil, gas, and hydropower operate in the frame of private-public partnership. Siberia has never experienced a shortage of electricity. Its cost was low; therefore, the enterprises were highly profitable. The market economy identified new trends: strengthening of the export-orientedness of the enterprises in the energy sector; attraction of foreign investment into organizing the construction of the newest enterprises; rapid introduction of new technologies; and increase in the uneven development of the region. Summary of historical experience can serve as a source of understanding of modern economic realities.
