Authors: Anisimov I A , Gorbunova A D 
Published: August 2020

Abstract
In modern cities, the high level of air pollution from road transport leads to the need to develop and operate new types of environmentally friendly vehicles. Currently, one of these is electric transport. The fleet of electric vehicles is growing rapidly. It necessitates the development of an appropriate charging infrastructure. However, the features of the location of the Russian Federation, which are predominantly low temperatures and variable climatic conditions, necessitate studying the existing charging infrastructure and developing new approaches to calculating the number and location of its facilities. The article presents an analysis of previously performed studies in the field of calculating the size and location of charging stations and a comparative assessment of the operating features of the existing regional charging infrastructure in the Russian Federation. The factors affecting the number of charging sessions were identified. The plan of further research is presented, aimed at calculating the number and location of charging stations in the regions of the Russian Federation.

Authors: Khlebova L P , Sokolova G G , Brynzova S E 
Published: August 2020

Abstract
We performed a bioassay of aqueous extracts from the bottom sediments of the Chumysh River near the settlement of Talmenka (the Altai Territory of Russia) using the Allium test. The presence of toxic components that caused a decrease in the mitotic activity of onion root meristem cells was revealed. The frequency of pathological mitoses, significantly exceeding the background value (on average, 16.3 times), indicates the presence of factors with total mutagenic activity in the samples. We found violations of chromosome divergences (emissions beyond the spindle, lagging, running off and premature chromosome divergence), abnormalities of the mitotic apparatus (multipolar, asymmetric, monocentric mitosis, polyploidy), bridges (single and multiple). The prevalence of spindle pathologies suggests chemical contamination of the bottom sediments. Stress factors present in bottom sediments activate adaptive mechanisms of the test-object cells, aimed at maintaining their viability and reliability of the transmission of genetic information to the next cellular generations. Such adaptation mechanisms include the formation of micronuclei and cell polyploidization.

Authors: Kosarev V F , Klinkov S V , Chesnokov A E , Smirnov A V , Vidyuk T M 
Published: August 2020

Abstract
The purpose of this work is to test the possibility of reducing the microhardness of particles of bronze powder CuAl10Fe3Mn2 by heat treatment. It is assumed that in the future, when obtaining coatings by cold gas-dynamic spraying, the use of less hard bronze particles will lead to more favorable conditions for the formation of coatings with improved characteristics. The conducted experimental studies allow us to conclude that the selected modes of heat treatment of this powder can noticeably reduce the microhardness of its particles (approximately by factor of 1.5). It should also be noted that heat treatment in a vacuum and in an argon medium leads to close values of the microhardness of the particles.

Authors: Patoding Hestikah Eirene , Sau Matius , Rombe  
Published: August 2020

Abstract
This study aims to determine the distribution of electrical power by considering the addition of generating capacity and the addition of networks using ETAP applications. The simulation results show that for the first scenario, the addition of generating capacity is carried out at Barru Bus without the addition of transmission networks, the voltage on bus 36 (Barawaja) stabilizes from 0.92 pu to 1.02 pu, with losses of 17.218 MW and 30.171 MVAR. This shows that power losses have decreased from 18.853 MW and 41.291 MVAR or decreased by 1.635 MW from power losses before the addition of generation in Barru, and the second scenario is the addition of generation at Bontoala and the addition of an express network. The system voltage that previously dropped became stable at the existing tolerance limit. Besides that, there were power losses when adding a generator at the Barru Bus. Thus, the distribution of electricity will be better when there is an additional generation at Bontoala Bus and the addition of an express network in the Sulselbar system.
