The work shows that it is expedient to use waste from oil production (oil sludge) as a raw material for obtaining porous fillers, which promotes the development of industrial ecology. Industrial ecology studies waste-free technologies - when waste from one production facility is used as raw material at another facility, which will achieve either waste-free production or maximum use of multi-tonnage waste. Ecological-economic systems are the subject of study of industrial or industrial ecology. Currently, the impact of industry on the environment is relevant because the activities of the fuel and energy complex, metallurgical, chemical, mechanical engineering, and many other enterprises cause significant and irreversible damage to nature. The fuel and energy complex is one of the main “polluters” of the natural environment. These are atmospheric emissions (48% of all atmospheric emissions), discharges of wastewater (36% of all discharges), as well as the formation of solid waste (30% of all solid pollutants). The conducted research has shown that due to the increased contents of carbon (16.2%) and calorific value (3300 kcal/kg) in the oil sludge, which burn or contribute to burning (calorific value) during firing, porosity is created in the ceramic material, and a porous material with low density, grade by bulk density of less than 400, is obtained. Based on a liquid-powder composition and waste from oil production - oil sludge, a porous filler with high physical and mechanical properties was obtained. The use of oil production waste in the production of porous fillers contributes to the disposal of industrial multi-tonnage waste, the protection of the environment, and the expansion of the raw material base for construction materials.

The paper considers working conditions characterized by the presence of harmful and dangerous factors of the natural and industrial environment, as well as the functional body state of builders performing various jobs. As the subject of scientific research, the levels of harmful and dangerous factors of the labor process in the warm and cold periods of the year and physiological indicators characterizing the dynamics of changes in the functional body state of builders working on open construction sites under the influence of the environment were chosen. The purpose of the research is to develop measures to create safe working conditions, as well as to improve the performance and maintain the health of builders. To achieve this goal, the following tasks were solved: the hygienic features of the working conditions of construction work were determined and the leading natural, industrial, harmful and dangerous production factors were identified; the quantitative and qualitative characteristics of harmful factors and the reasons for their formation were studied; professional characteristics of the work of builders with an assessment of the severity and intensity of the labor process were given; a set of measures aimed at optimizing working conditions and maintaining the health of builders was developed. The paper notes that the whole complex of harmful production factors affects the functional state and performance of builders of various professions.

Alkaline water electrolysers are widespread in many industries, including systems with hydrogen cycle of energy storage. One of the problems of modern alkaline water electrolysers is insufficient purity of generated electrolysis gases relative to electrolysis systems with solid-polymer electrolyte. In this regard, work on modification of existing porous diaphragms is actively carried out. One new area of research is the impregnation of new hydrophilic fillers into the composition of existing diaphragms and the transition to ion-solvate membranes. In this work the synthesis of zirconium hydroxide hydrogel inside a porous diaphragm with the hydrophilic filler TiO2 was carried out. This synthesis makes it possible to obtain a membrane with anion-exchange properties. A possible mechanism of OH- hydroxyl ion transfer by immobilized K+ ion was also proposed. The obtained results demonstrated the resistance of the membrane to concentrated alkaline solutions.

Processing of fruits and grapes and the creation of high-quality food items are completely consistent with the requirements of not destroying the produced crop. Making candied fruits from fresh fruits is a processed product that can increase the shelf life of the fruits by many years. The processing of fruits and grapes to produce high-value food products can be done without destroying the cultivated crop. Candied fruits, for example, are a processed product made from fresh fruits that can significantly prolong their shelf life for many years. Research was conducted in 2021-2022 at the Scientific Research Institute of Horticulture, Viticulture and Winemaking named after Academician M. Mirzaev “Department of Storage and Processing of Fruit and Grapes”. The results depicted that the dry matter content of candied fruits was generally higher than 70-75%, which was consistent across most sources. An analysis of processed products made from grain fruits showed that candied fruits made from apricots had a dry matter content of 94.5-97.2%, while peaches had a dry matter content of 93.8-95.1%, and plums had a dry matter content of 85.7-88.6%. It is worth noting that apricots and peaches contained particularly high levels of dry matter.

Development, implementation, and achievement of the desired results of Uzbekistan's stable progress and development of reforms are directly related to the professional personnel who organize these processes and their knowledge of innovative management. Because the correct determination of the directions of the reforms and the results to be achieved requires such qualities as high knowledge, potential, and professional skills from the specialist personnel. In addition, it is important to properly organize personnel management in every enterprise and organization in every field, direction, and place the most qualified personnel with the necessary knowledge and potential in every job. An important aspect of econometric analysis is that it is an analysis based on the assessment of the effects of factors that have an indirect, but not direct, effect on the change in the outcome variable. That is, in our analysis, if we define the indicator of employment of graduates as a result, the factors that indirectly influence its change are the scientific potential of teachers, the degree to which the institution where the graduate is trained is compatible with practice, the level of scientific research in the educational institution, education in harmony with international experiences. Factors such as have an indirect effect. In this article, medium-term forecast indicators of the level of employment of graduates in the training of agricultural educational institutions in the period of 2022-2027 have been developed. Also, the main directions of introduction of market mechanisms in effective management of agrarian education system are highlighted in the article.

Many farms in Uzbekistan, Ukraine, Kazakhstan and other republics arrange the production cultivation of chlorella and other microalgae in special installations and the use of suspensions as a protein-vitamin additive in the ration of farm animals. The use of chlorella and other microalgae in the fattening of cattle, pigs and poultry allows for additional weight gain, the elimination of avitaminosis diseases and improvement of product quality.

This paper seeks to contribute to continuing efforts to better understand and control the effects of urbanization on our environment and society by offering a thorough review of the most recent geodetic measuring techniques for build-up area growth. In this article, we give a case study from Uzbekistan that looks at current geodetic measuring techniques for expanding build-up areas. Uzbekistan is a fast urbanizing nation in Central Asia, and politicians and experts are both deeply concerned about the growth of the country's built-up regions. The case study, which offers a thorough investigation of the geodetic measuring methods and tools used to gauge and track the growth of the built environment, is focused on a particular metropolitan region in Uzbekistan. Therefore, this article gives a summary of current geodetic measurement methods, including remote sensing methods like LiDAR and satellite imaging as well as surveying methods like total station and GNSS. The case study also emphasizes some of the difficulties and restrictions related to these methods, such as the requirement for precise geodetic control points and the inadequacies of satellite imaging in regions with thick vegetation or cloud cover.
