The choice of material for the walls of the house is an important issue during construction. Walls take up a quarter of all the costs of building a house. If you carelessly take this choice, you can incur serious expenses in the future. When choosing materials for building a house, you need to measure your capabilities with a number of conditions and factors: functional load and purpose (summer house, housing for temporary or permanent residence); the climate of the area where the construction of the house is planned; project scope and number of storeys; the type of future exterior decoration of the facades; the presence and possibility of delivery of building materials to the facility; own budget. The article presents detailed comparative analysis of the most popular building materials (bricks, ceramoblocks, aerated concrete blocks, rounded bar, glued profiled beam, wooden frame, sandwich panels, wood). Each of them has its own advantages and has characteristics that may seem to someone as disadvantages.
Transport is one of the main tools in solving major political and economic tasks in ensuring the country’s defense capability. Management and monitoring of transport serve as an information basis for ensuring the functioning and development of the socio-economic system. In the modern world, transport management and monitoring of stable and long-term socio-economic transport development are of particular importance. This article discusses such concepts as transport management and monitoring, economic security and ensuring counteraction to its threats, threshold values of indicators of economic security and various approaches to their formation, innovative activity as one of the mechanisms for ensuring the development of the Russian economy.
This article analyzes the information about the developed, introduced, industrially mastered domestic composite materials on domestic raw materials according to the developed technologies for their production and application in industry, which allows recommending these developments as import substitution of dishes used by Russian manufacturers with non-stick coating of composite materials. The reducing of the dependence of the imported raw materials and components is not just a slogan. It is the prospect of using PTFE in dispersion-filled coatings due to a number of its unique properties: an abnormally low friction coefficient among structural materials (0.04-0.05 for steel without lubrication); high temperature resistance (decomposition onset temperature 418 ° C); high chemical stability (reacts only with melts of alkali metals, elemental fluorine at high temperatures); possesses excellent insulating properties. Based on the data on the Russian-made fluoroplast containing materials and coatings for various operational purposes created and introduced into production, it can be confidently stated: each of the developments individually and in the complex is import-substituting for technological, technical and quality indicators performed on domestic raw materials.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
