Increasing the competitiveness of enterprises in the world and domestic markets will make a huge contribution to the effective development of the country as a whole based on strategic analysis. It should be noted that the competitiveness of enterprises of this industry and their products depends not only on the conditions of the world market, but also on the degree of Organization of production of enterprises within the country. An important source of solution to this problem is the support of the state in the implementation of effective methods of industry management, new approaches to the organization of production, achievements of Science and scientific and technological progress in production. In the context of limited opportunities of society, despite the maximum support of the state, it remains a serious problem to increase the resource potential of enterprises based on strategic analysis, increase the material and technical level, its industrialization, and use of intensive innovative technologies in the near future. Thus, all of the above determined the relevance of the topic of the scientific article and its importance in the development of the country's economy. At the same time, despite the high relevance of the issue and the depth of scientific research, there is a lack of systematic approach and a lack of comprehensive consideration from a modern economic point of view. Also, in many theoretical aspects, only individual studies are devoted to the methodological and practical aspects of the formation of market conditions. Therefore, in order to replace it, there is a need to solve the issues of improving the economic efficiency of industrial enterprises by improving the economic mechanism for increasing the competitiveness of enterprises.

The article is devoted to the study of the problems of the formation and evaluation of digital competencies in the context of digitalization of general education. Currently, the problem of determining the level of formation of competencies among specialists in any field is an urgent task in the preparation and competitive selection of specialists. In the Russian education system, the training of future teachers and advanced training, additional professional education of experienced teachers should go to a new level of development in connection with the implementation of competency-based educational programs. And in these conditions, it becomes necessary to search for new approaches to assessing professional and digital competencies in general education teachers. Various models and algorithms for the formation of professional and digital competencies in general education teachers are studied. The approaches to the development of a cognitive model of competency formation are identified. A qualimetric approach to assessing digital competencies is revealed, as one of the most effective. Descriptors of key competencies of the digital economy, digital competencies are developed. The criteria for assessing digital and professional competencies formed by general education teachers were identified, the main indicators for evaluating the results were determined. A mechanism and means for assessing the level of formation of digital competencies, a scale for translating assessments of the level of competencies into a verbal assessment system have been developed. Based on the main indicators for assessing results, competency matrices have been developed for all stages of competency formation. An appraisal fund has been developed, consisting of various competency-level appraisals that have both formative and appraisal functions. This study allows us to develop a cognitive model of the formation of the digital competence of a teacher in the context of digitalization of general education. The results of the study can become the basis for the modernization of the system of training and retraining of teachers in the context of digitalization of general education.

This paper discusses the issues of the convergence process, which allows revealing the peculiarities of the interpenetration of customary law among some representatives of the Samoyed and Finno-Ugric peoples. The relevance of the study is due to the identification of the process of influence of customary legal views of the indigenous population of the Northern Russia on the formation of positive law. Objective: to study the process of approximation of customary legal norms, that existed among some Finno-Ugric and Samoyedic peoples both among themselves and with the customary legal elements of ethnic groups living in the neighborhood not excluding the interception between the norms of positive law and customary legal norms of Komi, Nenets, Khanty and Mansi. Results and scientific novelty: The work shows that the approximation of customary legal norms and institutions among these peoples occurred constantly both among themselves and with the customary legal elements of peoples living in territorial proximity with them. Usually legal institutions, which started to be realized in the 17th century, are distinguished. However, by the 19th century an integral system of legal customs is being developed, that was applied among the studied peoples. Attention is drawn to the fact that starting from the 17th century the Russian legislator “protected” the northern peoples from illegal influence and arbitrariness on the part of the officials. By the first half of the 19th century the legislator even sanctioned the most important principles of state policy in the “Charter on the Management of Foreigners”, where normatively not only the traditional forms of using patrimonial lands for indigenous peoples were fixed, but also the possibility of codification of customary law. The novelty of the study is seen in the fact that empirical material has been used to identify the process of interception of customary legal norms and institutions among the studied peoples.

Researching the content of the issue of professional and pedagogical mobility, we note the following. At the present stage of development of modern society, the problem of professional and pedagogical mobility is especially relevant. It is characterized by the growth of intensive and progressive changes in society, covering all spheres of human life, including the professional sphere. For a modern specialist to be successful and necessary, he must be mobile, ready for changes, able to quickly adapt to changing conditions, that is, he must be professionally mobile. Great importance is attached to the consideration of professional and pedagogical mobility as a pedagogical category. Concepts such as "mobility", "professional mobility", "pedagogical" are analyzed. On the basis of research and supplementation of these concepts there is a problem of independent understanding of professional and pedagogical mobility as a characteristic of the individual, which is reflected in the process of professional activity, readiness to develop, self-structuring and adapt to changes in the changing professional environment. The article clarifies the need to create a personal professional image, to organize and implement practical activities to get closer to this person, to detail the main steps for reorganization in connection with the changing conditions of the professional and pedagogical environment.

An important factor in increasing the efficiency of crop diversification in West Kazakhstan and reducing the dependence of crop productivity on weather conditions is the expansion of crops most adapted to unsustainable humidification of plants such as chickpeas, Sudan grass, sorghum, corn and sunflower. One of the ways to increase the productivity of Sudanese grass is to use its mixed crops with chickpeas, sunflower, corn and sorghum. Mixtures due to the best quality indicators of feed provide the maximum yield of feed units and digestible protein. The article presents research data on the study of mixed crops of Sudanese grass with annual crops in the conditions of the 1st dry-steppe zone of Western Kazakhstan. A comparative test of mixed crops by yield from digestible protein area units revealed the most nutritionally valuable mixtures. So, in the research of 2018-2020, the largest yield for digestible protein was obtained on the variant using sunflower for silage mixed with Sudan grass (1.65 c/ha), slightly lower on the versions of using a mixture of Sudan grass and corn for silage (1.58 c/ha) and a mixture of sorghum and Sudan grass for silage (1.55 c/ha).

Currently, the problem of the negative impact of petroleum hydrocarbons in the Caspian Sea has become catastrophic. Intensive pollution of marine waters by oil and oil products, from production, transportation and storage of hydrocarbons leads to the oppression of the sea ecosystem. Mechanical and physico-chemical methods for cleaning the marine environment are characterized by low efficiency, secondary pollution and high cost. The most promising is the use of microbiological methods for cleaning waters from oil pollution. In the article presents the results of the identification of reactive oxidizing bacteria isolated from the marine environment of the Caspian Sea, for further use in new biopreparation from oil pollutions. From the sea water in bulk berths Aktau sea port and the port of Bautino (North Caspian) allocated 27 hydrocarbon isolates of microorganisms having the ability to oil degradation of these strains selected the 4 most active cultures, which were identified as Bacillus cereus (2 strains), strain Bacillus sr.13 and Acinetobacter sr.10. Article is written by results of the scientific project of grant financing of Committee of Science of the Ministry of Education and Science of the Republic of Kazakhstan "Activization of the self-clearing ability of sea water of the Caspian Sea from oil products".

One of the priority areas of life safety and environmental protection is the creation of modified fire and explosion-suppressing powder compositions using man-made waste from various industries. Their use makes it possible to reuse substandard (expired) fire extinguishing compositions, possibly as substances that slow down the processes of explosion and combustion of materials. Fire and explosion-suppressing powders at the end of the shelf life must be regenerated or disposed of. For the regeneration procedure, i.e. restoration of the fire-extinguishing properties of the powder, it is sent to the manufacturing plant to restore its properties and characteristics. This allows you to modify the properties of the powder and produce an improved product. At the same time, a significant contribution is made to the development of a system for the rational use of natural resources, disposal of production waste, preservation of the ecological situation in the area, as well as prevention of emergencies and emergencies at industrial dumps. Comprehensive and rational use of secondary material and raw materials and wastes of various industries should take a certain place in the raw material balance of industry and in the prevention of emergencies.

According to X-ray phase analysis, the slag from the high-carbon ferrochrome production is represented mainly by forsterite Mg2SiO4, spinel MgAl2O4, partially amorphous glass phase and admixture of calcium orthosilicate Ca2SiO4. In the slag from the low-carbon ferrochrome production, the main crystalline phase is calcium orthosilicate γ-Ca2SiO4, as well as magnesium orthosilicate forsterite Mg2SiО4. The research results of specific surface area, average particle size determination and sieve analysis have shown that the slag from the low-carbon ferrochrome production is a finely dispersed gray powder with the following characteristics: the specific surface area – 295 m2 /kg, the average particle size – 6.8 μm, the true density – 3.01 g/cm3 , the bulk density – 739 kg/m3 . The research of the physicochemical and physicotechnical properties has established that in terms of chemical, mineralogical composition and refractoriness indices, the slags from the high-carbon ferrochrome and low-carbon ferrochrome productions can be valuable raw materials for heat-resistant materials.

In this article the kinetics of the process of sorption of copper (II) ions from aqueous solutions by polymer sulfonic cation exchanger, an elementary unit containing a heterocycle and a sulfonic group, under static conditions at a temperature of 298 K and a copper concentration of 2 mmol / mg is investigated. The sulfonic cation exchanger was preliminarily obtained by the reaction of polycondensation of diphenyl oxide and furfural with further sulfonation to obtain functional ionogenic groups in order to increase the extraction efficiency. The obtained kinetic curves of the dependence of the degree of extraction of copper ions from solution on time were processed using the Boyd, Adamson, and Myers equation, which describes diffusion in a limited volume of solution. The kinetic parameters of the sorption process (effective diffusion coefficient, etc.) are calculated, and the results obtained are compared with the data for the traditionally used industrial cation exchanger, which is a copolymer of styrene and divinyl benzene. It has been established that the process of sorption of copper (II) ions in the sulfonic cation exchanger phase is of an intra diffusion nature and corresponds to second-order kinetic equations.

In the work, a chemical analysis of humic substances based on oxidized coal of the Maikuben basin (Kazakhstan) is carried out. Humic acids were obtained on the basis of potassium humates by acidification with a 20% acid solution to pH = 3-4.5. The optimal conditions for obtaining nitrohumic acids from oxidized coals are: the duration of the process is 3 hours, the ratio of S:L = 1:5, the content of nitric acid is 64%, sulfuric acid is 96% and the composition of the nitrating mixture is 1:1 (g/g). Amminohumic derivatives were obtained in the presence of a 3% aqueous solution of ammonia using mechanical activation and ultrasonic treatment. The samples obtained were tested as an adsorbent for water purification from heavy metals. Humic acids and aminohumate showed the highest degrees of purification for zinc (99.0-100.0%) and cadmium (80.0-96.7%), and nitrohumic acid showed a high adsorption capacity for heavy metals like copper - 100.0 % and lead 82.9%. This is due to the fact that when interacting with heavy metals, humic acids and their derivatives (amino and nitro) form chelate complexes due to carboxyl, phenolic, nitro and amino groups. As a result of the study, the possibility of using them as non-toxic available sorbents for the purification of heavy metals in aqueous media has been shown.

The article emphasizes the inevitability of the formation of CO2 in the production of thermal and electric energy with the combustion of fossil fuel and analyzes the sources of carbon dioxide generation at power facilities in Kazakhstan. Technologies for the production of electrical and thermal energy with reduced generation of carbon dioxide, which are being implemented in a short time, are discussed. A possible method for quantifying the level of CO2 emissions for the conditions of Kazakhstan is shown, through the use of the specific consumption of conventional (carbon) fuels for production as a unit of thermal energy and / or electricity. A number of available and relatively cheap technological solutions are presented, which, when implemented, can significantly reduce carbon dioxide emissions. It is noted that these technologies can be implemented administratively and economically, and the formulations of the required decisions of the Government are given. For each of the proposed technologies, an assessment of possible volumes of reduction of carbon dioxide emissions is given and difficulties that may be encountered during implementation are indicated. A scheme for determining the degree of participation of a particular country in global carbonation is considered and it is shown that, depending on the method of "spreading" the total volume of emissions of a particular country, one and the same country can be both among prosperous countries and among a number of countries to which it is necessary to apply strict "carbon" taxes. It is noted that the determination of the share of a particular country in the form of emissions per unit area of the country's territory seems to be more "fair" taking into account the global nature of pollution.

On the base of analyses on the development of the construction industry as well as fires occurring in Kazakhstan, the article justifies the areas of fire prevention related to technical regulation that is the certification of materials, construction structures and engineering systems. The translucent building structures have increasing application in modern construction techniques. For such structures, the most vulnerable indicator is the fire resistance limit. A technical solution is offered to increase this indicator by using water irrigation. On the base of existing international and national regulatory documents, a number of methods has been developed for experimental determination of the actual fire resistance limit by cooling of structures with water in case of fire. Large-scaled fire researches have been carried out to determine the actual limit of fire resistance of the translucent partition made of tempered glass "Float" with the thickness of 12 mm, M1 grade both in the presence of water irrigation and in the absence thereof. The tests were carried out under standard and actual fire conditions. Optimal parameters of water irrigation are determined. On the base of research results, it is proposed to improve the construction standards in this field as well as methodological documents in the field of certification tests.

The possibility of organizing the production of bentonite mats as multifunctional watertight screens was thoroughly studied on the basis of the Taganskoye deposit in East Kazakhstan that is represented by three industrial horizons of alkaline, alkaline-earth and pharmaceutical bentonites, by their characteristics being one of the highest quality not only in Kazakhstan, but outside the country as well. Tagansky bentonite has a wide range of applications in various industries due to its unique chemical composition, including as a multifunctional material for the installation of watertight screens in the construction and rehabilitation of waste landfills of various origins. The article raises the question of the use in current practice of mandatory requirements for the arrangement of artificial protective screens during the construction of landfills, which should completely eliminate or minimize pollution of environmental components, the introduction of which could contribute to the development of local production of innovative materials based on Kazakhstan's bentonite deposits.
