A brief description of natural and artificial influences influencing the stability of buildings and structures is presented. Studying the seismic resistance of buildings and structures designed, under construction, erected, and in operation requires time to wait for seismic activity, which is not permissible; costs of manpower and resources, which is inappropriate. In this regard, a working hypothesis has been put forward that by artificially acting on soils with the help of detonation wave energy, it will be possible to induce vibrations, with the help of which it will be possible to study the behavior of building structures put into operation, the entire building and structure as a whole. The goal is set: - to investigate the behavior of structures under construction and in the operation of buildings and structures that perceive artificial vibrations caused by the detonation unit by acting on soils. To achieve this goal, tasks have been identified. A detonation (blast) wave is taken as a "tool" for force action. The theoretical foundations of the experiment are briefly presented and the developed scheme of a detonation tube and a shock wave with a general view of the installation causing detonation wave energy. A brief technique for carrying out field experiments is presented.
The analysis of the fishery companies of the republic shows that the main drawback in the fishing industry is the small volume of mass rearing of fish fry and the ineffective use of artificial groundwater reservoirs both – built in the 60-80s of the last century and those currently under construction. Due to the inappropriate size of the surface of these lakes, about 50-100 hectares, and insufficient depth in the ponds, small quantities of carp (2000-3000 units) are bred, large-scale repairs are being carried out, and the fish catch per pond with an area of 1.0 hectares is 1,0-3.0 tons, which, in turn, requires a large amount of water, mineral fertilizers and animal feed. The Innovative Fishery Center under the Fergana State University explores favorable hydro biological conditions for intensive fish farming, with an account of the climate of the republic, without the use of aerators, by organizing the circulation of water in the pond water, in order to provide fish bred in the reservoir with a sufficient amount of oxygen, considering the insufficient surface of the area (0.5-1 hectares – ponds with artificial soil, up to 1.5 hectares – natural reservoirs). As a result of carp care in poly culture, fish productivity is increased by 3-4 times as compared to the method of extensive fish farming.
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.
