Investigation of The Technological Process of Work and Justification of the Parameters of Raw Cotton

The article substantiates the method of compaction and the parameters of the compactor of raw cotton in an elastic container, which make it possible to increase the productivity of cotton pickers due to the large capacity of the container and the increase in the coefficient of use of shift time. A layered compaction method has been studied, which makes it possible to compact the cotton mass with its continuous flow from the bottom to the neck of the container. Theoretically, the pressure in various layers of the cotton mass, the distance between the inner ends of the sealing elements, the magnitude of the stroke and the speed of movement of the sealer, the volume of the container are determined, the coefficients are found that take into account the elongation of the height of the container and the layering of the seal. All parameters are substantiated from the condition of ensuring high productivity and reliability of the cotton pickers

The prospects of using various wooden pipes in the processes of substance exchange

This study introduces a novel approach to oil layering during the final distillation of vegetable oils using spherical wooden nozzles in the deodorizing champir. The nozzles, which move continuously due to the extraction of oil from the upper part of the device and the release of water vapor from the lower part, are shown to increase the contact surface between the liquid and vapor phases. This is demonstrated through the use of mulberry, walnut, and California nibs. The mobile floating wooden nozzles are found to enhance the interaction between the phases, leading to improved distillation outcomes

Fractal representations in image processing of remote sensing of the earth

This article explores the application of fractal representations in the image processing of remote sensing data for Earth observation. Fractals, with their self-similar properties and complex patterns, offer a powerful mathematical framework for analyzing the intricate structures found in natural landscapes. The study highlights the advantages of using fractal-based methods over traditional image processing techniques, particularly in capturing the multifaceted textures and irregularities of Earth’s surface features. By leveraging fractal geometry, enhanced accuracy in the classification and interpretation of remote sensing images is achieved. This approach facilitates better monitoring and understanding of environmental changes, land use patterns, and natural disasters. The findings underscore the potential of fractal representations to significantly improve the quality and efficacy of remote sensing image analysis, providing a robust tool for Earth science research and practical applications in environmental management

Integrated physical enhanced recovery method for high-viscosity oil reservoirs

The physical methods of enhanced oil recovery using electromagnetic fields are studied in this paper. Purpose of the work is to study the dependence of the main quantities that determine the volume of filtered oil, including the viscosity of oil, on the parameters (temperature, intensity and frequency) of thermal and electromagnetic fields, and optimize these parameters for maximum oil recovery factor using electric fields and steam treatment of the formation.It is proposed to combine the most effective and environmentally friendly methods to increase oil production. In the developed technique, methods of converting steam energy are used to create a torque of the drilling device with simultaneous steam treatment of the bottomhole zone of the reservoir. As well as the impact of an alternating electromagnetic field on the reservoir matrix and interstratal liquid fluids to create currents, increase the mobility of molecules of liquid fluids, and, as a consequence, increase the temperature and lower the viscosity of oil, which will increase oil recovery. As a result of numerous experimental experiments carried out using the original setup in the laboratory of the branch of the Tyumen Industrial University in Nizhnevartovsk, it was shown that a decrease in viscosity is observed only when exposed to simultaneous thermal and electromagnetic fields

The distribution of impurities along the height of the conical part of the hydrocyclone in the purification of hydrocarbons

The results of the study of the process of purification of hydrocarbons from mechanical impurities using hydrocyclone are presented. The distribution curves of the equivalent diameter of the equilibrium particles along the height of the conical part of the test sample of the hydrocyclone are constructed (D = 0.4 m, HK = 0.65 m). The analysis of the obtained data showed the possibility of centrifugal purification of hydrocarbon raw materials from particles with a size of 0.024 to 0.2 mm, depending on the physical properties of the phases to be separated. The distribution pattern of the equivalent diameter of the particles of HF = a (RC) can be used as a recommendation for the selection of the formulas of the conical part of hydrocyclones

The article presents the dynamics of changes in live weight for a year, measurements, body build indices and productivity of one-year-old pure-bred Kazakh fine-wool female lambs and crossbreeds of different bloods with German meat merino, when creating a fine-wool meat sheep breed in the south-east of Kazakhstan - “Etti merino”. The resulting crossbred offspring are characterized as large animals, with a high live weight and good meat forms

Scattering anisotropy in HgTe (013) quantum well

We report on a detailed experimental study of the electron transport anisotropy in HgTe (013) quantum well of 22 nm width in the directions [100] and [03 (1) over bar] as the electron density function n. The anisotropy is absent at the minimal electron density near a charge neutrality point. The anisotropy increases with the increase in n and reaches about 10% when the Fermi level is within the first subband H1. There is a sharp increase in the anisotropy (up to 60%) when the Fermi level reaches the second subband E2. We conclude that the first effect is due to the small intra-subband anisotropic interface roughness scattering, and the second one is due to the strongly anisotropic inter-subband roughness scattering, but the microscopical reason for such a strong change in the anisotropy remains unknown.
