In any production of products based on mineral fibers, one of the main types of equipment included in the line for the production of fiber products is installations for forming a basalt carpet or the so-called fiberizing chambers. The quality of finished products depends on their perfection. Currently, there are several widely used in industry methods for producing mineral fibers from the melt, which determine the various types and designs of hibernation chambers. In all chambers, the formation of mineral wool carpet occurs under the influence of hydrodynamic forces. Therefore, the study of such hydrodynamic characteristics as the rate of fall of individual fibers and clumps of these fibers and the hydrodynamic resistance of the carpet is of paramount importance in the design of new and reconstruction of old chambers. In this paper, we study the relationship between the strain rate and the viscosity coefficient of basaltic melt during fiber formation using a blown head developed by the authors. The substantiation of the process of fiber formation using a blowing head is given. Relations are obtained that establish the dependence of the strain rate in the fiber stream on the viscosity of the melt. Experimental data have been obtained that can be used to evaluate the effect of a basalt deposit on the dependence of the strain rate on the viscosity of a basalt melt. It was found that high-speed deformation of the melt greatly affects the quality of the fibers and the amount of waste in the production of fibers.

The paper is devoted to studying the following issue as a statement. What do we know and what we don’t know about arithmetic tables. Perhaps there is no mathematical problem as naive or as simple as finding a method for creating arithmetic tables. We confirm that the general method has not been found yet. This study provides a nonterminal solution to this problem. Why? The presentation of arithmetic material in essence, plus some accompanying ideas, makes it possible to develop them further in the system. Materials and methods. The system looks like this: a numerical table as Pascal's triangle and a symmetric polynomial in two or three variables. Some arithmetic properties of such tables will be found, studied, and proved. All this was made possible only after the successful decryption of the entire class of numeric tables of truncated triangles in the cryptographic system. Results. For example, the arithmetic properties of truncated Pascal’s triangle for finding all prime numbers have been found and presented, and then their formulas have been placed. In addition to elementary addition and subtraction tables, unlimited “comparison” tables of numbers are given and presented for the first time. Conclusions. For computer implementation of the objectives set, the rules of real actions that should exist for tables have been laid down. Only the recurrent numeric series should be used for this purpose.

The surface properties of microporous aluminosilicates are of primary importance in chemical technology and catalysis. The determination of the surface area, pore volume, and pore size and size distribution for microporous aluminosilicates is a complex scientific and technical problem related to both accurate measurements and the correct choice of a mathematical model that adequately describes the physicochemical processes occurring on the test surface. Currently, t-plot, as-plot, Dubinin-Radushkevich model, Dillimore model and Horvath-Kawazoe model are frequently used, each of which has certain advantages and certain disadvantages, to determine micropores in the material. It should be noted that t-plot model found the most frequent use. This is a consequence of the good correlation of volumes and pore areas obtained with its help with theoretically calculated values for various materials. In this point, the article provides a calculation of Zn-modified zeolite H-ZSM-5 surface properties using the t-plot model, for which nitrogen adsorption isotherms were originally obtained. The nitrogen adsorption isotherms of the initial zeolite H-ZSM-5 can be attributed to the first type of isotherms, and the modified samples to the fourth type of isotherms according to Brunauer’s classification. It was found that the initial zeolite is a typical microporous zeolite of H-ZSM-5 type, while the modified samples are micro- and mesoporous materials. Calculation of nitrogen adsorption isotherms using the t-plot model allows to determine the volume of micro and mesopores, which varied in the range of 0.11–0.14 cm3/g for micropores and 0.04–0.07 cm3/g for mesopores. Based on the obtained data, it can be concluded that when zeolite is modified with zinc at a zinc concentration less than 15 wt.%, micropores are not filled with zinc, while mesopores are predominantly filled and an additional surface of zinc oxide is formed on the external surface of the zeolite.

The article presents the results of a study of the prevalence of pollen allergy and allergies to house dust mites among the Bishkek population in 2019. The examined patients, aged 4 to 60 years, were divided into groups according to the age periodization of a person. Identification of general and specific IgE antibodies was carried out using modern methods of laboratory diagnosis of the immunological profile. Linked Immunosorbent Assay options such as Chemiluminescence Immunoassay (CLIA) and Immunoblotting were used. The obtained results indicate a widespread sensitization of the Bishkek population to pollen allergens, sensitization to house dust mite allergens is more pronounced in the form of a polyvalent allergy. There is also a tendency to increase the prevalence of allergic diseases among the country’s child population. Pollinosis occupies a leading place among allergic diseases in the country due to the fact that weeds prevail in the city’s natural vegetation, which is highly allergenic. Data on the incidence of allergic diseases in Kyrgyzstan, as well as abroad, do not reflect the true spread of allergies, because like most patients with mild forms of allergic diseases do not go to the doctor. Therefore, the early detection, prevention, and treatment of allergic diseases are one of the most important issues of modern medicine and biology. It is necessary to create annual flowering calendars of allergenic plants. Round the clock biomonitoring of the air to monitor pollen and air disputes is necessary to inform patients with hay fever. Preventive measures for patients with sensitization to house dust mite allergens include the prevention of mass reproduction of mites, namely the reduction of dust and humidity in rooms.

Circadian stress causes dysregulation of brain Homo sapiens software followed by impairment of the cognitive and visceral brains. The body’s circadian rhythms are programmed with a system of circadian genes. Circadian clock and circadian system — are the biophysical and biochemical regulators of immune protection. Circadian synchronization system is an evolutionary software product of biocomputer for survival and preparation of the organism for expected cyclic challenges, different epigenetic orientation. Understanding the temporal relationship between stressors and stress reactions is critical to understanding the molecular foundations of the physiology and pathogenesis of the disease. Chronic stress and circadian mismatch trigger a cascade of failures in the functioning of neurophysiological, neuroendocrine, and psychoneuroimmune mechanisms. Epigenetic loading and allostatic overload reduce both the body’s overall workability and its physical, occupational, and cognitive components. Circadian stress has a pathological effect on a person, in all his age periods of life. The level of disease exposure depends on the stability of the body’s protective systems. In the works of N. P. Romanchuk, it is established that modern solution to the problem of rehabilitation of cognitive brain H. sapiens with the use, on the one hand, tools and technologies of artificial intelligence, and on the other — multidisciplinary interaction of neurophysiologist with clinical universal specialist in the field of neurology, psychiatry, psychotherapy, psychoanalysis, and geriatrics. Modern artificial intelligence technologies are capable of much, including predicting cognitive disorders and cognitive disorders, through combined and hybrid neuroimaging, next-generation sequencing, etc., with the aim of initiating timely and effective rehabilitation of brain H. sapiens. Chronotherapy and psychochronobiological strategies to protect various groups and categories of the population from the effects of circadian stress allow blocking the transition of cognitive disorders to cognitive disorders. The skin is a unique synchronized near interface of the skin-circadian system, and the condition of the skin of the face and hands is an individual indicator (biomarker) of the effect of chronic circadian stress on accelerated (premature) aging of the human body.

This article discusses features of competence-oriented tasks used in mathematics lessons. Result of education is not only knowledge of specific disciplines, but also ability to apply them in everyday life, for use in the future training. And this largely depends not on the knowledge, skills and practices acquired, but on some additional qualities, competencies and more relevant to understanding the modern goals of education. Introduction of these concepts into teaching practice in school has required a change in the content and methods of education, specification of activity types that school students have to master at the end of an educational process and in the study of individual subjects. Success of today’s student in the future largely depends on his/her ability to acquire and develop skills, practices and competencies that can be used in any life situation. Therefore, it is necessary to educate children in readiness for change, developing of qualities such as mobility, constructiveness and ability to learn.

The article develops the idea of the presence in the Turkic languages of defective paradigms of personal predicative and personally–possessive conjugation. The category of personality / impersonality is an integral part of predicativity. Predicativity is the basis of any communication. It organizes and coordinates the speech and its components, being the constructive and semantic center of the utterance. Predicative is the framework of a proposal consisting of the main members of the proposal or one of them.

The article attempts to describe the gestures used by the representatives of Turkish culture and to classify them by comparing them with Russian gestures. While analyzing gestures, the principle of lacunarity, the absence of a phenomenon in a comparable language, was taken into account. The material of the study was the observation of the process of communication of representatives of various cultures with native speakers of the Turkish language, an analysis of literature, from which one could draw descriptions of certain gestures, materials of modern media. The research methodology is based on a comparative analysis of two languages in an asynchronous context. The study of gestures led to the following results: 1) the vast majority of gestures are lacunas (which have no analogs in another culture) for a representative of Russian culture; 2) gestures close in execution have distinctive features that do not allow them to be equated to Russian gestures in full. The possible coincidence of gestures in the aspect of execution, an increase in the number of borrowed gestures from Western cultures, once again proves that it is a nonverbal culture that is a ‘living substance’, influenced by cultural and socio-political changes in society. Nevertheless, in spite of this, today it is possible to establish and describe purely Turkish gestures, which are an integral part of communication with representatives of Turkish culture.

The article deals with the problems of the category of informativity of fictional texts, types of information, and the cognitive principles of distributing information in the text. The cognitive principles of iconicity, relevance, linguistic economy and redundancy, their verbalization in the fictional text are being discussed. The fictional text is characterized by two opposite tendencies. On the one hand, it tends to linguistic economy, on the other — to linguistic redundancy; both tendencies being equally important for the category of informativity.
