Abstract In the article, the use of the drug, Etafos-f at concentrations of 10-4 , 10-5 , 10-6 , 10-7 g/dm3. as an activator of activity of the biocenosis of activated sludge in the purification of coolant-containing wastewater. The study found that the addition of the drug in a concentration of 10-4 g/dm3 reduces the […]
Abstract The article proposes a technology for producing castings from aluminum cast iron with an aluminum content of 10 … 19% by centrifugal SHS casting, which is an environmentally friendly production and ensures the production of castings with high mechanical properties for structural materials. Due to the structural features of aluminum cast irons, they have […]
Abstract Due to its properties, natural gas can be used in all transport segments. Compressed natural gas is effective in transport, which is operated in urban locations. This is passenger, light freight transport, utility machinery. The environmental impact of large fleets is higher than personal vehicles due to large annual mileage, so the fleets of […]
Abstract Russian companies show significant interest in the implementation and development of process management. This is primarily due to the economic feasibility of its application. Secondly, with the opportunities that open up at each level of development of the process control system. The introduction of the process management technology of the enterprise increases in a […]
Abstract The water flow rate of the cooling system of tower cooling towers is considered as a controlled parameter. Using data on the irregularity of irrigation density over the cross-section, a regression model of the operating characteristic of a tower cooling tower was obtained, which establishes the dependence of the temperature difference on the irrigation […]
Abstract In this article, we analyze the existing methods for limiting water inflow in wells and the problems associated with them. The fields, their geological structure, fluid properties and geological exploration of the blocks under consideration were also considered and analyzed. To fully understand the problem, we analyzed the development status, the properties of polymers […]
Abstract The article discusses the use of a laser Doppler anemometer for measuring flow parameters with a high degree of turbulence in power plants. Due to the lack of rigorous analytical solutions of the equations describing the turbulent flow regime of liquid and gas flows, the use of experimental methods for studying flows is an […]
Abstract Holding the state accountable for the commission of an internationally wrongful act can be carried out by the injured entity directly or by contacting the international judicial bodies. The very process of resolving a dispute in such bodies is significantly different from the domestic judicial process, and court decisions taken by the international bodies […]
Abstract The article discusses the effective operation of the truck’s drive axle under the influence of extreme environmental factors. The influence of temperature and mobility of ambient air, storage and operation of the car is considered. A description of the loading conditions of the drive axle parts is given. The authors developed a classification of […]
Abstract In the work, thermal studies of compositions based on polypropylene were carried out and, depending on the composition of the composition, a comprehensive assessment of the quality of materials of polymer automotive components was carried out, since comprehensive quality control of materials is the confidence that the finished products are of high quality, which […]
