In developed countries, the share of continuously cast steel is approaching 100%, while in the domestic metallurgy industry, approximately 25% of steel is still cast into molds, which, in absolute terms, amounts to approximately 15 million tons/year. This is why research aimed at improving the technology for producing and processing ingots is relevant.

The effect of increasing plasticity (or superplasticity) of metals and alloys, which manifests itself during structural and phase transformations, is widely used in practice. The advantage of using the effect of kinetic plasticity of metals and alloys is the possibility of significantly increasing the plasticity resource, reducing forces during deformation and preventing cracks caused by a significant level of internal stresses. Currently, the effect of kinetic plasticity during martensitic transformation is widely used in the case of surfacing of hardening steels.

The durability and reliability of machines are largely determined by the fatigue resistance of individual components, since in the vast majority of cases, the main loading types for machine parts are dynamic, repeated, and alternating loads, and the primary failure mode is fatigue. Increasing the fatigue life of stainless steels is associated with the use of concentrated energy flows that modify the surface of the materials.

Analysis of the stress-strain state of horizontally layered massifs, including workings, geological faults, and fluid reservoirs, remains a pressing problem. Many scientists and specialists, including B.V. Vlasenko, G.I. Gritsko, A.N. Dinnik, V.E. Mirenkov, V.N. Oparin, and others, have contributed to its solution. To study the stress-strain state of the host rocks around the working contour, it is necessary to calculate the magnitudes of additional displacements, stresses, and strains. At the preliminary stage of their calculation, it is necessary to determine the stress-strain state of the intact massif. The authors proposed a method for solving boundary value problems for modeling the stress-strain state of heterogeneous massifs based on the finite difference method.

The Tashtagol iron ore deposit is characterized by powerful rock bursts. The danger of such dynamic events is generally undetectable, and in areas of subsequent working collapse, the burst-hazardous condition is not detected, since the primary failure source is typically located deep within the rock mass or is formed under the influence of a massive blast and the dynamic loading of shifting wall rocks. Taking into account the high energy of rock bursts, accumulated during geodynamic processes in high-ranking blocks, studies were conducted on the behavior of large sections of the massif, covered by observations at complex geodynamic sites on the surface and in the mine.

The country's socioeconomic development is inextricably linked to the modernization of production. The creation of new machines and mechanisms is only possible through serious fundamental research, ensuring high production efficiency and low production costs already at the design stage. Gear-and-lever mechanisms are widely used in the mechanical engineering, metallurgy, and mining industries, particularly those in which the axles of some wheels are movable (planetary gears). Therefore, the issue of improving planetary gears is highly relevant.

The development, improvement, and restructuring of the country's transportation network should be based on those parts that have not lost their economic significance (the main railway network) and the creation of new elements, the need for which is driven by the need to intensify commodity exchange not only within the country but also in global economic relations.

The control system for the continuous casting machine-2 withdrawal stand at the NKMK Electric Steel Mill-2 is based on a two-zone subordinate control scheme, tuned to average parameters in the magnetic flux attenuation speed control zone. This setup does not meet the quality and control precision requirements of modern technological processes.

Rising energy prices and increasing environmental pollution are forcing us to reconsider our approach to the use of traditional energy resources and consider alternative energy sources, their technical prospects, and potential solutions.

Currently, alongside coal mining, its beneficiation is developing rapidly. The inevitable result of the beneficiation process is the production of waste – small coal particles and mineral inclusions. A significant amount of coal beneficiation waste has already accumulated; it is stored at beneficiation plants and pollutes the environment. One method of utilizing coal beneficiation waste is its combustion in a vortex furnace of an automated power-generating complex in the form of a coal-water slurry.

At the Department of General and Analytical Chemistry of the Siberian State University of Management, systematic studies of the thermal melting constants of lanthanide halides are being conducted with the aim of studying the periodicity of changes in the physicochemical properties obtained by a unified method for similar compounds of the lanthanide series. This study is devoted to determining the thermal melting constants of neodymium tribromide (NdBr3). In the series of lanthanide tribromides, NdBr3 occupies a special place - this substance undergoes a crystalline morphotropic transition, which consists in the fact that the hexagonal structure of the UCl3 type, characteristic of lanthanum, cerium and praseodymium tribromides, changes to an orthorhombic structure of the PuBr3 type.

Concrete for road construction must possess high compressive and tensile strength, crack resistance, durability, and abrasion resistance. To achieve these characteristics, fiber-reinforced concrete is recommended. Domestic and international experience shows that dispersed reinforcement of concrete with various fibers is the most optimal and is increasingly used in many areas of construction. Steel wire, glass, basalt, and polypropylene fibers are commonly used as fibers, but experience has shown that their use is either expensive (steel fibers) or ineffective (glass fibers).

The construction industry's raw material base includes both natural and man-made (industrial waste). One of the main ways to reduce material intensity in the production of building materials is through the use of secondary mineral resources (SMR). The Construction Materials Laboratory at the Siberian State Industrial University studied various man-made products of metallurgy: ferrous and non-ferrous metallurgy slags, foundry and gas cleaning waste; ore and coal beneficiation waste; burnt rock; industrial waste from the energy sector; mining waste, and others.

Currently, the accumulation of finely dispersed, unsaleable coal waste in waste heaps has led to the development of coal-water fuel technologies. The need to burn water-saturated coal fines requires the development of coal-water slurries and combustion methods. One promising area is the combustion technology of coal-water slurry fuel (CWSF) in a vortex furnace.

When drinking water is collected at treatment plants from surface sources, a significant amount of contaminated water is generated from the blowdown of horizontal settling tanks or clarifiers containing a suspended sediment layer and the backwash of rapid filters. This water has high levels of suspended solids, color, aluminum, and other constituents.

The task of developing rational innovation management programs for the implementation of electroslag processes (ESP) for hardening rapidly wearing parts of metallurgical equipment with new composite materials (CMs), discussed below, consists of finding the most typical solution for a given set of conditions for increasing the service life of the equipment and, consequently, the productivity of the main units. In this case, it is necessary to select only those management methods that best suit a given situation of reducing production costs and improving product quality, promoting the enterprise's innovative activity and its competitiveness.

Currently, in the context of the transformation of the education system and, consequently, changing financing conditions, many budgetary institutions, like commercial enterprises, must independently manage their development. The extra-budgetary activities of organizations are a source of financial resources that enable them to efficiently carry out their statutory activities and implement their development strategy, ensuring high-quality services, decent salaries for all institution employees, and adequate material and technical equipment. The regulatory documents being developed to define planning methods and pricing for services provided are general in nature and do not take into account the complexity of integrating the financial flows of all structural divisions, the structural and functional characteristics of the educational institution, its competitiveness, as well as the climatic conditions, the demographic situation of the region, and the solvency of its population.

The philosophy of act has long been firmly associated with the name of M.M. Bakhtin in Russian philosophical thought. A strong notion of "before Bakhtin" and "after Bakhtin" paradigms has emerged in these reflections. However, in the current situation, circumstances have arisen that actualize not only individual ideas, philosophemes of Bakhtin's concept, and his reflections on the crisis of act, but also the entire experience of understanding the essence of act and its nature within these paradigms.

At the current stage of development in Russian society, there is an urgent need to develop and implement new approaches to implementing social policy for people with disabilities and shift the focus of its implementation to the regions. N.I. Lapin notes that a region is both an object of state governance and a subject thereof. Regional authorities oversee the activities of subordinate organizations and regulate the region's political, administrative, social, and industrial infrastructure. A specific, practical description of a region allows us to present a set of indicators (indicators, indices) characterizing the state and dynamics of a given community, the quality of life, and the social well-being of its various strata, and, in accordance with these indicators, to formulate an individual social policy system for a given entity.

Children enjoy a special privileged position in any country. Concern for the younger generation manifests itself in a wide variety of areas. Among these areas, protecting the rights and legitimate interests of minors should be paramount.
