The work is devoted to the study of the efficiency of shielding the radiation exposure of heavy ions depending on the phase composition of Cu-Bi coatings. As a method of producing protective coatings, an electrochemical deposition method was used. The change in phase composition was carried out by varying the applied potentials difference during deposition. The study found ...

Turbines are one of the most important means of producing clean energy, as they do not cause any negative emissions affecting the environment. Recently, the need to design turbines capable of facing strong winds has appeared because the currently designed turbines must be cut off in such circumstances. This study aims to find the best design parameters and investigate the ...

A behavioral model of the modular reduction device with optimal hardware costs was designed in CAD Quartus Prime Lite Edition. An algorithm of operation is implemented in the Verilog HDL language. A method is used where, at each step of the calculation, the value of either tripled, doubled, or single value of the module is subtracted from the most significant bits shifted ...

The study examined the intricate relationships between embankment slope configurations, toe drain designs, and drawdown scenarios. It utilized a unique combination of numerical, physical, and mathematical models. The investigation involved 16 numerical models and 8 physical models with distinct characteristics. The research explored the correlations of key parameters: matric ...

The use of large-span structures made of glued wood in countries with large timber reserves in Finland, Sweden, Norway, Russia, the USA and Canada has shown that this can be quite interesting and expressive from the architectural position of the building. Sports facilities, sports and sports facilities, sports facilities, sports and cultural facilities. The practice of ...

The commissioning of the new fragment separator ACCULINNA-2 at FLNR JINR is accomplished. The separator is destined to expand the possibilities in studies of dripline nuclei performed with the exotic secondary radioactive ion beams (RIBs) at energies of (5 – 50) AMeV. The projected high transmission and purification level were confirmed experimentally for a number of RIBs in ...

Nano-dimensional crystalline cadmium sulfide is a semiconductor that exhibits size-dependent optoelectronic properties, determined by the effects of quantum confinement. Due to these effects, it is possible to adjust the optical properties of the final cadmium sulfide clusters by varying their size. In this work we report the results of a theoretical study of CdS nanoparticles ...

The design of shallow foundations is performed in accordance with different building regulations depending on geotechnical and geological conditions. This paper involves the design calculations applying Kazakhstani and European approaches. The design of shallow foundations in Nur-Sultan city in Kazakhstan was implemented by the calculation of bearing capacity and elastic settlement ...

Neutrons can be an instrument or an object in many fields of research. Major efforts all over the world are devoted to improving the intensity of neutron sources and the efficiency of neutron delivery for experimental installations. In this context, neutron reflectors play a key role because they allow significant improvement of both economy and efficiency. For slow ...
