Study of the adsorption nature, emission - adsorption parameters of La, Sm, Gd films on the surface of the sharp monocrystal of the molybdenum alloy - rhenium CCC and GPU structure and the establishment of general laws and regulations of the adsorption nature of these rare earth metals.

The research paper provides the potential danger of sediment dust, the need to take into account the amount of dust in assessing the risk of ignition in the production room. The data obtained made it possible to determine the time of collection of dust sufficient to form an explosive dust air mixture.

The article deals with the issues of hydrometallurgical processing of beneficiation products, the reasons for the loss of valuable components and the problems of rational use of natural mineral resources. The process, technological schemes, technological parameters and standard conditions for cyanidation of enrichment products are analyzed.

This article discusses the physics and its connection with other sciences. The main task of modern physics is to comprehensively study the material world, to find the laws of its structure and motion, and to connect these laws to each other. Motion is the main property of matter and the condition of its existence. The form of movement of matter is divided into several main types: mechanical, physical, biological and social. There was an opportunity to separate disciplines based on the study of the type of movement.

Today, the digital land cadastre is one of the most important activities of economic sectors, and the land cadastre has been created and been developing since the beginning of the personal society. In particular, with the development of the tax system, the study of land resources and land cadastre has become a primary necessity. At a certain stage of the society's development, along with the number of land areas, the quality condition began to be calculated, and later there was a need to calculate the amount of profit received from lands with different productivity. Land reform is the main basis of agrarian reforms related to the market economy. Without successfully implementing it, without instilling in the peasants a sense of ownership of the land and the results of their labour, it is impossible to carry out agrarian reform at the necessary level without introducing the types of land use that fully meet the requirements of the market economy. In this case, land assessment, including soil assessment and economic (normative) land assessment data will be of great practical importance, and this, in turn, will serve as the main foundation for the implementation of the "Digital Uzbekistan - 2030" strategy in our country.

The article studies the influence of parameters on the reaction rate of catalytic dimerization of methane, kinetic relations in the flow differential quartz reactor (P=0,1 MPa, Vcat =0.5÷2 ml, СН4:О2=2:4, contact time 0.1÷0.09 sec) in the temperature range of 750-580 ℃. The influence of temperature on methane conversion and product selectivity, the influence of oxygen and hydrogen impurities on methane conversion and acetylene selectivity, and the dependence of ethane selectivity on temperature were discussed. At different concentrations of methane with a volume ratio of СН4:О2=3:1 in the mixture, the influence of temperature parameters on selectivity for acetylene was studied, a reaction mechanism was proposed and a kinetic model was developed for obtaining ethane, ethylene, acetylene and acetic anhydride from methane.

The article under discussion discusses poultry meat and its processed products. The authors of the article consider that in recent decades there has been an increase in the importance of poultry meat and its products in human nutrition due to its high consumption properties. Poultry farming in Uzbekistan has always played one of the most important roles in supplying the population with high-quality products. The accumulated data on the nutritional and biological value of poultry meat testify to its compliance with the medical and biological requirements for raw materials for the production of mass food products, including children's.
