Many years of operation of top-blown converters have convincingly demonstrated their advantages, including high productivity, the ability to process cast irons of various chemical compositions, the relative simplicity of the equipment, the relatively high durability of the lining, and the ability to consistently produce low-carbon metals.

One of the most difficult problems in rolling theory is the determination of the stress-strain state of metal during deformation in grooves, which is explained by the complexity of the mathematical apparatus necessary to describe the processes of metal deformation in grooves, taking into account the entire variety of acting factors. Since the indicators of the stress-strain state of metal characterize the tendency of deformed blanks to the formation and development of defects, the calculation of such indicators is important in the design of roll grooves and rolling modes.

The structure and properties of structural ceramics depend significantly on the state of the starting components (phase and elemental composition, dispersion, and morphology of the starting powders), the method of their production, compaction, and subsequent sintering. One promising direction in the production of structural ceramics is the dry uniaxial pressing of nanopowders under the simultaneous action of powerful ultrasonic vibrations, which helps reduce wall and interparticle friction. This allows for denser packing of powder particles and, consequently, higher compaction density of any geometry. During the pressing of ultrasonic ceramic powders, the dispersion, morphology, elastic-plastic properties, compaction density, and the homogeneity of their microstructure can be influenced. However, the question of the influence of powerful ultrasonic exposure on the phase composition, parameters of the crystal structure and defects of metastable powder nanoparticles belonging to the class of polymorphic materials still remains open.

Recent research in the field of magnetism has focused largely on the study of low-dimensional systems, which is due to the prospects for creating new materials on their basis with broad functional capabilities for opto- and nanoelectronics, measuring equipment, information technology, communications, etc. One-dimensional structures are obtained either by electrochemical deposition, or by deposition on a stepped surface using lithographic methods, or by rapid cooling of the melt in a rotating liquid. In addition, there is a class of quasi-one-dimensional magnets (Ising magnets), which can be described within the framework of the one-dimensional Ising model.

The aim of this work was to analyze the defect substructure of high-intensity electron beam-modified electroexplosive composite coatings formed on the copper surface.

When using certain grades of flux, the required mechanical properties of the weld metal (in particular, impact toughness at low temperatures) are not always achieved due to the formation of a large number of non-metallic inclusions. Most of these inclusions are oxides (regardless of whether they are exogenous or endogenous). The content of non-metallic inclusions in the weld metal, in turn, depends on the amount of total oxygen. Since the solubility of oxygen in solid metal is low, the total oxygen content characterizes the level of contamination with non-metallic inclusions. When using existing fluxes for welding low-alloy steels, an increased total oxygen content and, consequently, an increased number of non-metallic inclusions are observed. Currently, a reduction in the content of non-metallic inclusions in weld metal during automatic submerged arc welding is achieved by using weakly oxidizing fluxes. However, such fluxes have unsatisfactory welding properties and are rarely used for welding low-alloy steels. When using oxidizing fluxes, the weld metal is saturated with oxygen as a result of silicon and manganese reduction processes.

The coal industry's development strategy is inextricably linked to increasing the load on underground working faces and designing mining areas with a minimum capacity of 2-3 million tons of coal per year. However, technical upgrades focused on high-performance equipment, coupled with increased mining depths, have led to a significant increase in methane emissions into mine workings. Under these conditions, safe mining of methane-rich coal seams is only possible with the use of effective gas management methods in mining areas.

The transition to greater depths in the development of minerals requires additional research to study the deformation and strength properties of the coal rock massif under increasingly complex geomechanical conditions.

The safe operation of hazardous industrial facilities (HIFs) is receiving increased attention worldwide. This issue is particularly pressing in Russia, as more than 60% of industrial equipment has reached its design life, and in the energy sector, more than 80%. Damage to HIFs can and does lead to accidents and man-made disasters with fatalities. Numerous examples have been cited over the past 10 years.

By now, a significant amount of coal washing waste has accumulated in Kuzbass. This is due to the imperfection of the technologies operating at coal washing plants, since the coal content in coal washing waste can reach 25% or more. Coal washing waste, although it contains a significant amount of coal, has an extremely limited scope of application as a fuel, since it is characterized by high ash content, moisture content, and a finely dispersed particle size distribution.

The pace of construction in the Kemerovo Region is increasing year after year, but new multi-apartment residential buildings with load-bearing brick walls have practically ceased to be commissioned. The main reasons for this are the high estimated costs and construction time. Therefore, strong, durable, and environmentally friendly brick buildings have been replaced by prefabricated panel buildings, as well as buildings with monolithic reinforced concrete frames, in which brick is used only for the construction of self-supporting walls and partitions.

The current state of uncertainty in the global and Russian economies challenges companies to overcome the crisis through specific and effective measures. The need to find new technologies to overcome the crisis at Russian enterprises necessitates the use of modern methods for reorganizing the structure of economic entities. Mergers and acquisitions are considered a key element of such restructuring in modern economic theory and practice.

Currently, many domestic educational institutions are participating in the development of modern tools for managing the educational process with the goal of increasing its effectiveness through the computerization of the pedagogical and organizational activities of the university. For the successful functioning of an innovative university, a unified concept for creating a working model of the information and educational environment in accordance with the standard is necessary, taking into account the national and regional components of this system and international experience.

Physics is a science that forms the foundation of natural science education and the theoretical thinking of future specialists. The renowned physicist, Academician L.A. Artsimovich, quite succinctly and figuratively defined the knowledge of physical science for humanity, emphasizing its ideological and polytechnical nature: “Modern physics is a kind of two-faced Janus. On the one hand, it is a science with a burning gaze, which strives to penetrate deep into the great laws of the material world. On the other hand, it is the foundation of new technology, a workshop of bold technical ideas, the support and driving force of continuous industrial progress.” At the same time, the colossal volume of knowledge accumulated by physics today makes the task of teaching it extremely difficult. Under these conditions, the only solution is to intensify the learning process by eliminating material that duplicates secondary school, bringing the physics curriculum closer to its actual content as a science, modernizing and structuring the program, and using the achievements of modern teaching technologies. Learning can be considered successful if the student has actively mastered a set of basic standard physical models; uses them constructively, revealing the mechanisms of physical phenomena and the structure of physical objects; and has a culture of physical thinking.

Sociology, as a type of social practice, defines the conditions and prerequisites for the implementation of political practices, revealing their inherent tendencies, laws of effectiveness, and the probabilities of various possibilities. In analyzing the interaction of dominance and subordination, it focuses primarily on the second aspect of this relationship: the provision of mechanisms for subordination, support, and acceptance of power structures. Sociological analysis involves identifying patterns of political behavior, the characteristics of the population's perception of power, and their sociostructural determinants.
