“…As for developed countries, which are characterized by an increasing role of the service sector and a decreasing role of industry, there are certain specific features. Firstly , their production capacity may be located in other countries due to globalization; secondly, although the relative role of industry is declining, its capacity as such continues to increase and modernize [65][66][67][68]. Thus, the role of industrial production remains significant.…”

The Kyrgyz Republic, as a developing country with a socialist past, has great opportunities for further economic development. An important factor to consider is the growth of the manufacturing industry, which highlights the significance of analyzing this sector within the country. This study centers on the potential contribution of the Eurasian Economic Union (EAEU), of which Kyrgyzstan is a constituent, towards the advancement of this industry. The research aimed to evaluate the current manufacturing capacity of the Kyrgyz Republic in the industrial sector and to comprehend the influence of the EAEU on industry growth. The main methods that were used during the writing of the research were analysis, forecasting, abstraction, and historical analysis. The work analyzed the industrial sector of Kyrgyzstan within the framework of its integration into the EAEU. The research assessed the historical background of Kyrgyzstan’s accession to the EAEU and the subsequent harmonization of national legislation with the provisions and requirements of the union. In addition, data comparing the industrial production and growth rates of Kyrgyzstan, Armenia, and Kazakhstan have been presented, highlighting notable trends and differences. The work examines specific components of the manufacturing industry of the Kyrgyz Republic, the manufacture of food, beverages, and tobacco products; rubber and plastic manufacture, and non-metallic mineral goods; manufacturing of basic metals and metal products (excluding machinery and equipment); and supply of electricity, gas, steam, and conditioned air. It also talks about the manufacturing sector's importance in Kyrgyzstan, current trends, and possible future improvements, and it enables the assessment of the country's involvement in the EAEU.

Experimental studies of the effect of adding the antifriction additive Multi-Tech-Conditioner to lubricating oil on the power of mechanical losses of a rotary piston engine were carried out, the purpose of which was to reduce the cost of potential energy of a compressed working fluid to overcome friction forces. The experimental data obtained make it possible to estimate the value of irretrievable losses of the available power of a rotary piston engine at the stage of its design and operation. Experimentally, a positive effect of the addition of the Multi-Tech-Conditioner antifriction additive to lubricating oil on the change in the power of mechanical losses of the engine was established, which was reflected in a decrease in total losses over the entire operational range of change in the rotor speed by 11.8 %. As a result of the research, it was determined that the losses for pumping strokes (gas exchange) in a rotary piston engine amount to 31.6 % of the total power of mechanical losses. An assessment was made of change in the mechanical efficiency of a rotary piston engine with a hinged-cam mechanism for converting motion under the conditions of applying an antifriction additive to lubricating oil. It has been established that the addition of the Multi-Tech-Conditioner additive to the lubricating oil in a ratio of 1:14 makes it possible to increase the mechanical efficiency of a rotary piston engine depending on the speed by 3.8–5.5 % for all operating pressures in the inlet receiver. Based on the generalization and systematization of the obtained experimental data on the use of the Multi-Tech-Conditioner additive, the most rational operating ranges of a new design rotary piston engine were identified. The maximum mechanical efficiency of a rotary piston engine is achieved in the load range of 65...75 % of the rated power, and the speed range is 63...70 %

Exploring and improving the unloading mechanism of grain silage is one of the most significant tasks in the agriculture and grain processing industry, as it can help both improve productivity and quality of work and contribute to the economic efficiency of enterprises in general. The study aims to improve the efficiency, safety, and grain quality of grain silo unloading mechanisms, with a focus on universal enhancements while also addressing unique challenges of different discharge mechanisms. Geographical considerations may impact maintenance and technology adoption but do not alter the core goal of enhancing productivity and safety. The methodology employed in the study involved a combination of qualitative and quantitative analyses, with a focus on statistical methods such as regression analysis and correlation analysis to assess the performance and efficiency of grain silo unloading mechanisms, identifying influential factors, and providing recommendations for optimization. The study highlights the critical importance of the unloading mechanism in grain silo operations, as it significantly affects productivity, grain safety, and overall efficiency. Inefficient mechanisms can lead to process slowdowns, bridging, grain jamming, and quality loss. Optimizing these mechanisms can enhance grain unloading, minimize energy and maintenance costs, and improve safety for personnel, ultimately reducing the risk of grain quality issues. Consequently, the study underscores the practical significance of enhancing grain silo unloading mechanisms to boost productivity, reliability, grain safety, and costeffectiveness.
