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 addresses the issues of mathematical modeling of water flow velocity and pressure parameters. The theoretical basis relies on the Bernoulli and Navier – Stokes equations, while the dynamic and kinematic viscosity of water is analyzed. To determine...
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...
The article presents the results of an experimental study of the operation processes of a solar photovoltaic power plant (SPVPP) with a total capacity of 40 kW, connected directly to the power grid, for one year. To improve the reliability of the SPVPP, the nu...
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...

The article presents the results of research conducted on fields cleared of grain and the study of the physical and mechanical properties of the soil in these areas. The results obtained were used to maintain soil fertility in agriculture and create optimal co...
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...
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...
It is known that the demand for energy in the world is increasing, traditional fuel resources are not evenly distributed on the globe, and the negative impact of carbon dioxide gases on the environment is high when using them. Today, determining the relative h...
Today, due to the increase of hard-to-extract natural gas reserves in the world, as a result of the liquefaction of productive layers, the cases of the decrease in the flow rate of wells are increasing year by year. When using gas and gas condensate wells, liq...
The article describes the results of the application of rank paleotectodynamicanalysis methods for the first time to study conditions of formation and age ratio of tectonic structuresof different intervals of Mesozoic-Cenozoic geological history within the cen...
One of the main tasks of salt transfer research is the selection of a mathematical model that corresponds to given conditions based on the study of the structural features of individual horizons of the studied rock strata, the patterns of movement of substance...
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...
The use of solar photovoltaic devices is becoming increasingly important in stabilizing energy security and solving environmental problems. Particular attention is paid to the scientific substantiation of factors affecting the efficiency of solar photovoltaic ...
In this research work, the energy efficiency of the introduction of heat pumps into the energy supply systems of buildings in the conditions of Karshi city was evaluated based on the thermodynamic cycle of the heat pump operating on the basis of a low-temperat...
In modern conditions of intensive increasing the electricity consumption in all spheresof human activity, limited hydrocarbon fuel reserves, as well as the severity of environmentalproblems in the energy sector require the development and implementation of mor...
