Methodological solutions for level measurements of socio-economic security of the industrial sector
Статья научная
The basis of the description of the values of socio-economic security of the production system is based on the principle of extreme dispersion of industrial States along the axis of maximum security - the least security, taking into account the configuration of the composition and the degree of satisfaction of the society's needs, which determine the goals of ensuring socio-economic security. Groups of requests satisfied at various levels are formed on the systematization of requests proposed by Belarusian scientists. The degree of socio-economic security of the industrial sector, determined by the probability to meet all kinds of demands of society, is dependent on the emerging structure of production capacity. The acquired data allowed to form appropriate methodological solutions for level measurements of socio-economic security of the industrial sector.

Methods of drawing portrait genre in fine arts
Статья научная
Art is one of the forms of social expression, and it was created as a result of visualizing the images created in human thinking, emotions and abstract thought by means of images. The images created as a result of the impact of the external world surrounding a person, the processes and events occurring in it on feelings and thinking are the basis of image creation. Portrait painting, which reflects a person’s inner world, feelings and emotions through facial expressions, lines, likeness and mimicry, eyes and gaze, which are considered as a mirror of mood, is considered a very complex genre of fine art and painting. The portrait genre, which is one of the main genres of painting and graphics, has taken a very wide place in fine arts. As in other genres, portrait works take their content from public life and reflect public existence through specific artistic images and influence public life. Therefore, the portrait artist is not satisfied with giving only external signs of a person in his works, such as external resemblance, pose, movement and facial expressions. At the same time, the tries to show the spiritual world, psychological characteristics and what kind of character the person he paints.

The reliability of the results of any forecast is dependent on the validity of the selection of objects and the definition of its subject area. Suppose that in the total number of objects of the forecast it makes sense to exclude the signatures of the industrial sector (industrial objects) and non-industrial objects, which, despite the relation to the external environment, have a specific impact on the position and formation of the industrial sector. To clarify the selection of the objects and the subject of the forecast of socio-economic security of the industrial sector, the following methodological approach is proposed. The forecast objects are oriented by the location of the sources of industrial sector hazards - “internal environment - external environment” - by the scheme of interelement connections in its structure and the importance of communications outside the structure (to distinguish objects it is proposed to mark them symbolically in accordance with the “industry objects” and “non-industry objects”). The subject field of the forecast is formed by the qualitative and quantitative properties of the objects of study. The task is to identify those objects from a large number of probable objects and their data that will allow to identify negative phenomena and processes capable of implementation in the current period (updated threats).

Статья научная
Magnesium is a rich element on earth, with high reversible, cycle stability and antitoxicity, low cost, and high-volume hydrogen capacity, its theoretical hydrogen storage capacity up to 7.6 wt %. Magnesium-based hydrogen storage materials are considered as one of the most promising hydrogen storage media. However, due to its high thermodynamic stability and slow hydrogen adsorption kinetics, the high adsorption temperature and long adsorption time limit its practical application. In order to overcome the thermodynamic and kinetic obstacles of magnesium-based hydrogen storage materials in practical application and improve the hydrogen storage performance of MgH2, catalytic modification is a very effective method at present. This review summarizes the preparation methods, characterization methods and reaction basis of various catalysts modified by MgH2.

Modern aspects of etiology, mechanisms, pathogenesis and diagnostics of ovarian formations
Статья обзорная
This review focuses on ovarian lesions. Ovarian tumors occupy the 3rd place among all tumors of the female genital organs, and 7th in the overall structure of malignant tumors, so the problem of timely diagnosis and treatment of ovarian lesions remains relevant. The share of benign ovarian tumors accounts for 70-80%. Among benign ovarian lesions, epithelial lesions are most common - tatami up to 16% and cystadenoma up to 22.8%. Histogenesis of ovarian formations is not fully understood, which explains the contradictions in the origin of a particular tumor. For the first time, features of the mechanisms of neoplasm formation have been described by A. Knudson et al., his team was one of the first to develop and publish the theory of ‘double strike’, interpreting the mechanisms for implementing sporadic and hereditary forms of neoplasms. Ovarian cancer - both on the part of the etiology and the clinical picture of a heterogeneous genetically determined pathology. The basis of the emergence of this group of tumors is the mutation of the genetic apparatus of the cell...
