Currently, sulfoxide methods are of greatest interest for the practice of separation of lead-copper concentrates. The selection processes based on the use of sulfoxides such as sulfuric acid, sulfite salts, etc. should be included in this subgroup.d. Typically, these reagents are used in combination with other depressors [3].

The main advantage of sulfoxide methods is the lack of dissolution of noble metals and higher efficiency compared to many known methods.

The subgroup under consideration includes a method using sodium sulfite, iron vitriol and sulfuric acid for halenite depression Currently, about thirty methods of flotation separation of lead-copper concentrates are known.

The product is a white or yellow powder in appearance, odorless or tasteless. The substance has high thermal and salt resistance, does not contain toxins. If the reagent is introduced into the aqueous phase of the solution, it acts as a thickener and helps to reduce the filtration rate. The moisture content of the substance is less than 10 percent. The material complies with international standards for this substance.

This article provides for a healthy lifestyle among the population and young people, schoolchildren and students of colleges, institutions, improving medical culture and how to protect one's health. Also, conducted on new pedagogical technologies and innovative methods.

The manuscript shows a short data used using fluorescent probes to study the effect of polyphenol PС-7 on changes in the dynamics of intracellular Ca²+ content in rat brain synaptosomes, depending on the site of glutamate binding on calcium channels by a specific mediator with glutamate. To measure the amount of cytosolic Ca²+ synaptosomes, we calculated using the Grinkevich equation. It has been shown that polyphenol PС-7 binds to the β1-subunit of the voltage-gated calcium channel and allosterically changes its conformation so that the conductivity for Ca²+ ions increases through the channel, the blocking effect of polyphenol PС-7 can be explained by its binding to voltage-gated calcium channels and activating them.

The importance of assessment in the educational process and international assessment systems were discussed. There is also information on the dependence of a child's educational opportunities on genetic factors and upbringing. In this regard, it is recommended to use Gardner's "theory of multiplicity of intelligence" to make the most of the child's potential. The article presents a map of the “multi-intelligence theory” of intellect and comments on the relationship of types of intellect to the cerebral hemispheres. A "Child Intelligence Diagram" is also recommended for practice.

In chronic experiments in laboratory animals, studied toxicological perspective new antiarrhythmic effect of N-deacetyllappaconitine for the treatment of arrhythmic states, an original herbal preparation based on Aconitum leucostonum, Ac.Septentrionale was created. During 2,5 months of intragastric administration in animals exposed to all doses of N-deacetyllappaconitine, no deviations in the parameters of the functioning of the nervous system were found, therefore, this value is the lowest effective (threshold) dose in a chronic experiment.

This article is about the study of the production of clothing suitable for men's non-traditional statures, which analyzes the types of statues and their deviations from the standard form. in addition, the article describes the methods of designing clothes for men with an unusual type of figure using examples.

Physical education and sports should be an integral part of the general culture  of the citizens of the country.Therefore, the principle of health-oriented physical education requires attention to the responsibility of participants to respond to their health and when exercising. This article scientifically explores the principle that physical education is health-oriented.

This article gives a brief overview of optical devices used in shooting. This article is intended to acquaint students (students) of higher, secondary special and secondary education institutions with information about optical devices used in shooting.

The article presents the results of testing the use of Angren dry remote active ash and slag in Portland cement as an active mineral additive. It was found that Portland cement with the addition of Angren dry remote active ash and slag renders karrazastoy, ekanomet clinker and it is proved that hydro removed ash and slag (2011 year) does not recommend as an active mineral additive. Therefore, dry remote active ash and slag is recommended for use as an active mineral additive in the production of cement, improving its construction and technical properties. The possibility of using Angren dry remote active ash and slag as an active mineral component for producing cements with low corrosion resistance is shown. Angren dry remote active ash and slag contributes to the formation of the structure of the cement stone, increases its density and strength against aggressive ions, causing increased resistance in aggressive environments. And save up to 30% of cement. It has been established that Portland cement with the addition of Angren dry remote active ash and slag has an intensifying effect on the formation of clinker minerals. Therefore, the Angren dry remote active ash and slag is recommended for use as a mineralizing additive in the production of cement. Use of chemical industry waste with replacement of expensive natural production and consumption waste. At the same time, an environmental problem is being addressed.

The article gives an innovative scientific definition of waste terms through a creative approach to the literature and assets. For the first time, a new classification was developed to take into consideration the waste created in emergencies, and its practical significance was revealed.

The teaching method is one of the basic categories of teaching methods. In the general didactic sense, the concept of a method includes the methods of interrelated activities of the teacher and students, aimed at achieving the goals of education, upbringing and development of students. In this understanding, the methods can be universal, applicable to teaching different disciplines, although they have their specific embodiment in each discipline. For a language teacher, methods are important as sources of knowledge, skills and abilities formation. These methods include: working with a text, a book, a teacher's story, conversation, excursion, exercises, the use of visualization in teaching. Depending on the independence of educational actions performed by students, active and passive methods are distinguished; by the nature of the work of students - oral and written, individual and collective, classroom (classroom) and home.

A healthy lifestyle is the process of forming a person striving for maturity, able to overcome the most dangerous and harmful influences, factors affecting active work, strong physical and mental state. In order to conduct effective socio-political and spiritual and educational work among young people, trainings have been introduced in each educational institution aimed at increasing medical knowledge about a healthy lifestyle, personal hygiene, family spirituality, and the negative impact of harmful influences. Diseases from healthy childbirth. It plays an important role in shaping the principles of a healthy lifestyle in the minds of our youth.

This article scientifically examines the importance of healthy living in the development of society and the achievement of physical maturity.

This paper describes a statistical analysis of lineaments based on multi-temporal Landsat 8 imageries in the Fergana Valley (East Uzbekistan). The results of the statistical analysis showed that determined that the count of lineament structures changes by months. It was also noted that the Namangan region is more prone to the manifestation of lineament structures. The maximum count of lineament structures was in July. And in November, we observe a sharp decrease in lineament structures. According to the results of the rose diagrams, various orientations are observed for these months. There is a coincidence of directions.

Radio Astronomical Observatory of Suffa, and new proposals for radioastroclimatic (seeing) studies for atmospheric radio prediction are described. The paper presents the results of many-year (2015-2020) and seasonal observations of the astroclimate at the construction site of the RT-70 radio telescope on the Suffa plateau (an altitude of 2400 m above sea level). Observations were carried out automatically every 10 minutes throughout the year, starting from November 2014.

This article is about clothing used for shooting briefly illuminated. This article is intended to acquaint students of higher, secondary special and secondary education institutions with information about clothing used in shooting.
