Music is a melody that reflects the inner emotional experiences of a person. "Music (Greek - art of muses) is an art form that reflects human emotional experiences, thoughts, imagination through the consistency or set of musical sounds (tones, melodies)." The genesis of music goes back to primitive times. There are different theories about this in science. Some researchers associate the emergence of music with a primitive ritual, some with the labor process, others with hunting processes (pre-hunting and post-hunting games).

In the work, the activated Ni-Co catalyst for the conversion of methane to carbonates was prepared by placing  γ-Аl2О3 in solutions of nickel and cobalt nitrates. The time dependence of methane conversion was studied for different catalysts. In these processes, CО2/CH4=1:1,41 1 ratio was obtained.

As a result of the research conducted, the methane effect of Co on Ni/Al2O3  catalyst for conversion. The following possible mechanism was proposed.

The purpose of the work is to study the effect of Co on the conversion of methane to carbonate, and the dependence of these processes on catalysts of different compositions, time and temperatures.

The article discusses the advantages of using axiological scales in the analysis of the level of values reflected in the Uzbek language proverbs. Axiolinguistics is a science that integrates axiology and linguistics and is interrelated with linguoculturology, psycholinguistics, sociology, and cognitology. Axiolinguistics has emerged as a result of highlighting the role of lexical units in the expression of axiological content. The article discusses the main goals, tasks and main issues of axioinguistics. Linguistic definition of evaluation and value, methods of evaluation are described. Scales are the methods of measurement and evaluation used in the exact and natural sciences. In recent years, as a result of the use of scales in the socio-humanitarian spheres, linguistic, psycholinguistic, axiolinguistic scales have emerged. The scale method evaluation level is also important in determining the norm of the relationship. The role of axiolinguistic scales in illuminating the content level reflected in the proverbs is illustrated by case studies. The results and conclusions are presented on the basis of the axiolinguistic scale. Recommendations for using this method are given.

President of the Republic of Uzbekistan Sh. Mirziyoev "Today, our Uzbekistan is rising to a new, higher stage of development based on the main principle: "From national revival to national rise." "During the large-scale reforms implemented in our country, the role and influence of the state language in our lives is increasing more and more," he said. In fact, today, when Uzbek language is given the status of the state language, when we celebrate it as a national holiday, it is very important to raise our language to a higher level.

The article covered the process of developing a wireless temperature monitor with a radio module for researching solar cells under heat and humidity conditions. Through this, the possibility of using the equipment and panels installed in the solar power plant in the organization of technical service was considered. The possibility of improving the quality of service has increased if the workers know the temperature and humidity of the solar cells while monitoring the amount of energy produced. In this article, we have implemented wireless communication between two Arduino microcontrollers and temperature and humidity monitoring using an NRF24L01 radio module, DHT11 sensor and display.

The article is devoted to the consideration of phraseological units-euphemisms related to the phraseological-semantic group of the socio-political sphere. The study of several euphemism dictionaries and selected material indicates that the appearance of a significant part of the units of this group is associated with the peculiarities of the political and social development of English-speaking countries, as well as other European countries. Concluded that it is the euphemistic function that is most suitable for veiling and hiding from the general public unsightly political and military actions nominated with the help of euphemism phraseological units.

The purpose of this article is to identify the most effective and common forms of political euphemisms, as well as the specific features of terminological changes.

The given аrticle deаls with testing the validity of mаchines using strаin gаuges аs well аs the dynamic behаvior of a vehicle the forces and moments аcting on the wheels. The level of accuracy should be acceptable. Since all the tire models used in the literature calculate the tire forces and moments based on parameters which are difficult to measure or estimate online, in this paper a different approach is undertaken. A wheel rim from a formula student car was fitted with strain gauges and a study was conducted with respect to the feasibility to estimate the static load applied to it. The results of this research highlight the differences encountered and discuss possible solutions.

The article justified the urgency of ensuring the environmental safety of water intake and treatment facilities in water supply systems by creating a complex of specialized protective equipment. The operation of water supply systems was analysed, as a result of which it was determined that the environmental safety of water intakes was insufficient. To solve this problem, the scientific justification of the ecologically sustainable operation of the natural-technical system of the specialized type "natural water environment - water management complex - agricultural water supply system" was carried out. The proposed systematic approach to solving the vital problems of ensuring the environmental safety of water intake facilities of water systems is to provide high-quality water to consumers in any operating conditions (mud, suspension) of agricultural water supply systems. At the same time, the complex of water and intake treatment facilities improves the river ecosystem.

The social relations that arise in the release from responsibility due to the fact that the guilty person regrets his act, the conditions for the release from responsibility due to the fact that the guilty person regrets his act, and the criminal law norms regarding the basis of their application are analyzed.

In this article, the logical, systematic, logical-legal, comparative-legal methods of research are widely used. In particular, the formation of the doctrine of the crime compound and its stages of historical development are described in detail. Including, first of all, the most Continental (Romano-Germanic) and Anglo-Saxon (Common) from large law families the objective side of the crime structure in the doctrine of criminal law existing in the family of law and The concept of "actus reus" is scientific about them by the scholars of each family of law views, studies, similarities and differences between them described in detail. Also, the objective aspect of the crime and "actus reus" concept has been analyzed in comparative law and the problematic aspects in them are sequential described. In this article, the main focus is on the objective aspect of the composition of the crime advantages of signs and "actus reus-mens" in criminal law in the Anglo-Saxon legal family rea" on the "corpus delicti" (composition of the crime) consisting of a criminal act aspects related to the shortcomings of the theory are both theoretically and practically justified. At the same time, criminal law exists in the Anglo-Saxon (common) law family scientists in the doctrine J.Austin, M.Moore, D. Husak, J.Fletcher, H.Morris, M.Gore, A.Enker, W.Blackstone, G.Williams and Russian belonging to the continental (Romano-Germanic) family of law scientists A.N.Trainin, N.F.Kuznetsova, V.N. Kudryavtsev, D.M.Molchanov and others, as well as national scientists A.S.Yakubov, M.Kh.Rustamboev, S.S.Nayimov, M.Usmonaliev and Scientific works of P.Bakunovlar and others were used. At the same time, continental (Romano-Germanic) and Anglo-Saxon (common) law countries are crimes analyzed the criminal legislation of the Republic of Uzbekistan in this regard specific proposals and recommendations for improvement have been developed.
