The regularities of the oxidation of combustible substances in the presence of various catalytic systems have been established, and catalysts have been selected on their basis for the sensitive elements of a highly sensitive ammonia monitoring sensor. The use of the created sensors significantly reduces the analysis error, increases the service life and stability of the device, and at the same time improves the reproducibility and selectivity of determining the micro concentration of ammonia.

To look at the process of creating modern clothing within the framework of the structure of the clothing assortment from the point of view of the block-modular design method. Classification of types of decoration of modern clothing based on the Uzbek traditional costume.

The given article provides a brief overview of the literature on the history of the development of foam concrete in the industry of building materials and products. The results of work carried out by foreign and domestic researchers on the production and improvement of the technical properties of foam concrete are presented.

The results of studying the composition of lime sludge waste from the production of chemical fertilizers are presented. The analysis of the chemical composition of CaCo3, Ca (OH) 2, NaOH, Na2CO3, MgO, non-solvent substances in water, moisture in lime sludge is presented. The percentage was studied in order to use lime waste as a secondary raw material for fine aggregate in the production of aerated concrete and aerated concrete.

The article is devoted to the development of an imitation fuzzy model of the natural gas drying process during its preparation for transportation. To solve the problem, adaptive means of automatic control have been proposed, which will almost completely compensate for the change in the parameters of the gas drying process. The paper proposes methods and models of optimal adaptive control aimed at increasing the efficiency of gas drying. The use of the proposed model allows parametric and structural optimization of production in order to improve the quality of gas drying.
