Technological processes for restoring parts by hot stamping have a number advantages: shaping occurs in dies a simple design, existing forging and pressing equipment is used with the use standard automation and mechanization tools. In the process restoration parts by hot plastic deformation, it is possible to restore the shape and dimensions the worn surface, as well as to obtain the required microstructure the metal the restored part, which makes it possible to increase its service life due to subsequent thermo mechanical processing. A study was made the reasons for the loss performance the ball pins the torque rod, designs dies were developed for the restoration worn solid parts by the method hot forging. Parts are restored by creating targeted metal flows into the wear area using hot plastic deformation. It has been established that the hardness the metal in the middle part the restored part \"Ball pin\" increased by 30 ... 32% in relation to serial parts. When heated to the temperature forging and deformation the metal, the internal damage the metal accumulated inside the part is restored.

New crown complexes with biological prop ethers have been created, and the structure of the produced crown complexes has been determined using elemental analysis data from studies of these samples' IR, mass, and NMR spectra. According to the contact duration between the phases, the pH and solution's composition, the structure of tetracyclines, and their concentration, an organized research of the sorption of tetracycline on a magnetic composite with crown ethers was conducted as a component of the study. Crown ethers and Fe3O4 (CE@Fe3O4NPs) nanoparticles were produced under certain conditions, and the composites' magnetic and structural characteristics were evaluated. Tetracyclines were evaluated for their ability to bind to the nanostructures produced by CE@Fe3O4 NPs. These structures have no negative effects and remain safe for consumption. Crown ethers are currently produced using novel techniques, and new magnetic sorbents made with crown ethers and Fe3O4 nanoparticles have also been developed. It has been shown that magnetic sorbents composed of Fe3O4 nanoparticles and crown ethers have superparamagnetic characteristics. The research in consideration identifies and discusses the characteristics of tetracyclines' sorption behavior. There are several methods for concentrating tetracyclines for sorption onto a magnetic sorbent using Fe3O4 nanoparticles and crown ethers from aqueous solutions. Our research has demonstrated, using the example of produced CE@Fe3O4 NPs nanostructures, that mixing the nanotechnological approach with the methods of supramolecular chemistry offers a large adsorption effectiveness.","PeriodicalId":511802,"journal":{"name":"Advances in Science and Technology","volume":"4 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-04-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140710163","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Inaccuracies made in the choice of equivalent circuits and calculations using the MATLAB Simuling programs and others increase the errors. In a number of cases of automatic reclosing, and in problems with nonzero initial conditions, transient processes require special calculation programs. The analysis of transient processes plays a special role in the selection of elements of relay protection and automation systems in the analysis of design calculations. In many cases, when carrying out computational project work, rather expensive, sometimes not very accurate programs and software are used. Therefore, carrying out design calculations for simple cases of switching and short-circuit, sometimes turns into inadequate and undeserved dependence on foreign specialists. The presented article examines the results of transient processes and voltages when the transmission line is turned on to a sinusoidal voltage source and, as a result, automatic reclosing.","PeriodicalId":511802,"journal":{"name":"Advances in Science and Technology","volume":"5 9","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-04-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140712212","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
