Abstract. This paper presents the results of a comprehensive evaluation of a small-scale hybrid biogas plant for farms in Uzbekistan. The system under study includes a 0.5 m³ bioreactor, a 2 m² solar collector, and a 0.55 kW photovoltaic panel, providing therm...
The article is devoted to the analysis and demonstration of approaches to the calculation of combined heating and cooling systems using heat pumps and renewable energy sources (RES) under the conditions of Uzbekistan. Calculation results are presented, and the...
The results of the analysis of perforation works in productive horizons are presented. It was established that the increase in well production rates after horizon perforation depends on the depletion level of recoverable oil reserves. It is shown that at the l...
Abstract. The article presents the preliminary results of field experiments on the use of the rain irrigation method in the cultivation of the Turon winter wheat variety zoned for the conditions of the Kashkadarya region. It is known that grain crops, includin...
This article analyzes the thermal efficiency of energy-active window units (EAWUs) for passive houses under the climatic conditions of Tashkent city (6th climatic zone of Uzbekistan) based on the Giovanni bioclimatic diagram. The study focuses on the role of w...
This article discusses the solution to the problem of identifying complex hidden relationships between varieties by clustering using the DBSCAN algorithm, dividing the characteristics of soft wheat varieties into groups (reflecting the growth and development o...

In this study, the potential for reducing the specific heat consumption of residential buildings in the Tashkent climate was examined by utilizing a solar parabolic concentrator in combination with a heated floor system. The developed mathematical model incorp...
This article analyzes the role and importance of investments in effectively organizing the processes of reproduction in agriculture. Highlights the opportunities provided by investments for introducing innovative technologies, developing infrastructure, using ...
The geological and physical conditions of the multi-layer gas condensate field Urga are presented. Using the material balance method, the drainable gas reserves were estimated. Low efficiency of field development was established based on a comparison of reserv...
Considered one of the most widespread ancient crops in the world, soybeans are currently grown in 91 countries covering 118 million hectares. Main producers: USA 70-90 million tons, Argentina 50 million tons, China 20-40 million tons, India 6-7 million tons, R...
. Currently, one of the problems facing the Uzbekistan Railways JSC is that trains being accepted into the station from the lack of empty station tracks are waiting in front of the entrance traffic lights or at neighboring stations. As a result, the number of ...
Currently, in world practice, scientific research and design work is being carried out on the development and creation of passive solar heating systems. If the heat storage wall of a passive solar heating system consists of a perforated heat storage wall, then...
Under conditions of steady motion, the resulting pressure losses due to friction along the length cause a number of characteristic features of the movement of a real gas compared to the movement of incompressible liquids through pipes. At the same time, the ph...
Today, there are several types of photovoltaic cells on the commercial market, and their efficiency in natural conditions varies depending on climatic factors. Taking into account that the weather conditions of different regions are different, there is a probl...
This article presents a detailed analysis of the potential for integrating digital innovations to improve oil extraction rates from reservoirs. The process of increasing oil recovery from reservoirs, or EOR, is defined as strategic intervention in a reservoir ...
The causes of spoilage and deterioration of minerals extracted from the Tepaquton mining complex are systematically analyzed and the main causes of spoilage and deterioration are identified. In addition, reasonable proposals for reducing degradation and failur...
The global transition to renewable energy sources has led to a dramatic increase in research and development in solar energy technologies. Among them, flat solar water heating collectors are attracting a lot of attention due to their potential to improve energ...
Using a solar simulator, a photoelectric-thermal system integrated into an open-loop air building with a working fluid was experimentally investigated. Options for building-integrated photovoltaic/thermal systems and systems using polycrystalline silicon photo...
