Abstract Using nuclear gamma resonance (Mössbauer) spectroscopy in the backscattering geometry, the surface layers of graphite cast irons irradiated with nitrogen ion fluxes were studied. New phases were discovered and identified that are formed in the surface layers of the studied alloys during the implantation of nitrogen ions. A relationship has been established between the […]
Abstract The paper presents an analysis of methods for monitoring the flow and pressure of crankcase gases, a method for measuring the pressure of crankcase gases using the built-in diagnostic system. The authors investigated the prospects, advantages and disadvantages of the method of diagnosing an engine by the flow rate and pressure of crankcase gases, […]
Abstract The paper describes aspects related to the design stages of modern residential buildings. Reflected is the lack of requirements for the presence or absence of stagnant zones in residential premises of apartment buildings. Convective flows were simulated in the living room of a multi-room apartment of a multi-unit standard panel house. It is shown […]
Abstract The ability to find a derivative and use it in different fields plays a large role in the practical activities of students, both in technical specialties, and in economic, and humanitarian ones. The concept of the derivative is one of those mathematical concepts that are intersubjective in nature and are actively used in economic, […]
Abstract The process of spraying a liquid has a wide range of applications in various fields of technology. The spray characteristics primarily rely on design features of the sprayers and their modes of operation. It is known that values of the flow rate and capture radius of the sprayed jets depend on the pressure, nozzle […]
Abstract Environmental problems are becoming more acute for modern humanity with every passing year. The quality of atmospheric air is of particular concern. It is polluted by the industrial emissions, car exhaust, energy enterprises and other anthropogenic sources [1]. Atmospheric air is a vital component of the natural environment, an integral part of the environment […]
Abstract The work is devoted to the study of the influence of automobile roads and walkways surface conditions on the public consciousness. The formation of certain qualities in a person, and their reflection in reality were investigated. The main method of the research was the group survey, as well as the personal interview, in which […]
Abstract In all four forms of administration of justice (constitutional; civil; administrative; criminal proceedings) for participants in procedural relations, it is possible to: use the native language, as well as use the services of an interpreter. However, the practice of implementing the constitutional right to judicial protection in the context of “language guarantees” is sometimes […]
Abstract The study of the issues on use and exploration of outer space, which were made possible thanks to the development of new means of technology, required concerted action by different states. International cooperation in space exploration is also promoted by the high cost of research and the economic feasibility of joint projects. Despite the […]
Abstract We have considered a possibility of modifying the roofing bitumen by the developed mixed thermoplastic elastomer (TPE) in view of its increased resistance to atmospheric aging. We evaluated the preliminary selection of TPE composition with accordance to the time of dissolution in the bitumen melt and main physical and mechanical properties. In order to […]
