Abstract
The growing of high-strength low-alloy steels use in the welded metal structures manufacture is accompanied by an increase in the requirements for the reliability of prediction results in the “composition-structure-properties” system. The fractal analysis methods use makes it possible to establish a metal structure characteristics numerical parameterization, the metallographic analysis of which gave only a qualitative assessment. The article shows the fractal analysis possibilities for the numerical evaluation of such of the structure of weld metal characteristics as the total length of grain boundaries, the distribution of dislocations at the grains structural boundaries, the distribution density of non-metallic inclusions accumulations with a distance less than 5r from one another. There was show the possibility of the structure and non-metallic inclusions numerical parameterization in the “structure-fractal-properties” system for predicting the mechanical properties of the low-alloy high-strength steels weld metal

Keywords: low-alloy steel; metallographic; fractal analysis; metal structure; non-metallic inclusions; mechanical properties.

Stotska O. – BIOTRANSFORMATION OF BREWING WASTE

BIOTRANSFORMATION OF BREWING WASTE

Abstract
Brewery wastewater contains dissolved organic substances, therefore, for their highly efficient cleaning, it is necessary to use suitable and economically beneficial ecological technologies. Substances dissolved in water cannot be filtered or precipitated using coagulants, removed using flotation, etc. Some of the impurities can be removed by physical and chemical methods, but the main part of them is in the solution. Effective treatment of such wastes is possible only if biotechnological methods of treatment are used.

Keywords: brewing production, biotransformation, biotechnology, wastewater, methane fermentation, biogas, feed biomass.

Abstract
Cold resistance is one of the most important properties of materials that determine the reliability and durability of structures and equipment in low temperature conditions. The article presents the results of an analysis of the influence of chemical composition on the cold resistance of steels. These data can serve as a scientific basis for the development of advanced technologies for the production of promising materials for extreme operating conditions.

Keywords: cold resistance, steel, chemical composition, alloying elements, mechanical properties.

Abstract
The literature review over the past 20 years indicates a particular interest towards foreign accent perception in business environment and reveals biased attitude of natives, whether employers or employees, to non-nativeness in terms of phonological competence in the studied field. While the attitude of natives has been thoroughly researched, immigrants’ opinions might vary and require careful consideration. This study aims to examine to which extent, if any, a foreign accent in the German language affects professional communication of Russian-speaking immigrants living and working in Germany (in fields including IT, finance, healthcare, education, etc.). In total, 108 participants aged 22-62 completed a questionnaire, the primary purpose of which was to explore whether a foreign accent is perceived as a hindrance in business environment. The research included a quantitative analysis of gathered statistical information processed via JASP software, as well as a qualitative analysis of open-ended items. The major finding indicates that for 39.8% of the participants, a foreign accent has no influence on interactions within a business context. According to the results of the questionnaire, 31.5% of the respondents have never found themselves confronted with a problem of not being understood due to a foreign accent. Finally, for more than a half of the surveyed participants, namely 53.7%, their foreign accent had no bearing on the accomplishment of job-related tasks as part of the working process whatsoever.

Keywords: foreign accent, second language, accentism, German linguoculture, workplace, professional discourse

Abstract
The interaction of manganese atoms with atoms of group VI elements (S, Se, Te) in the silicon lattice has been studied. The formation of electrically neutral molecules with ionic-covalent bonds between Mn atoms and group VI elements, which possibly lead to the formation of new binary unit cells Si₂B_VI⁺⁺Mn^— in the silicon lattice, has been experimentally established. It has been established that in Si <S, Mn> samples, intense complexation occurs at a temperature of T=1065˚C, respectively.

Keywords: single crystal, interactions, electrically neutral molecules, diffusion, complexation, thermal annealing.

Antonov A. – THE CORRECTED VERSION OF THE SPECIAL THEORY OF RELATIVITY

THE CORRECTED VERSION OF THE SPECIAL THEORY OF RELATIVITY

Antonov A.
PhD, HonDSc, HonDL, ResProf., H.ProfSci
Independent researcher, Kiev, Ukraine

Abstract
This article shows that the version of the special theory of relativity (STR) presented in all physics textbooks is incorrect, since relativistic formulas obtained therein are incorrect. They are incorrectly explained using the wrong principle of non-exceeding the speed of light and have led to incorrect conclusions about the physical unreality of imaginary numbers and the existence in na-ture of only our visible universe. This version of the STR proved to be in demand only because its authors were not able to explain physical sense of imaginary numbers. The article provides three proofs of physical reality of imaginary numbers and explains their physical sense in the theory of linear electric circuits, relativistic physics and astrophysics. This made it possible to obtain cor-rected relativistic formulas, from which appropriate conclusions were drawn.

Keywords: Special theory of relativity, imaginary numbers: Multiverse: dark matter: dark energy.

Abstract
Based on cognitive and discursive analysis of texts of Russian-language Internet communication, the authors identify the features of the modern content of the concept “new life” as a constant of Russian linguoculture. The authors consistently describe the conceptual features of the considered constant and demonstrate their relationship with its figurative realizations and emotional and evaluative halo in the analyzed Internet texts. The authors present the value component of the constant, highlight its dominants and emphasize its ambivalence.

Keywords: Russian concept “new life”, cognitive and discursive analysis, texts of Russian Internet communication

LEXICAL AND SYNTACTICAL STYLISTIC DEVICES BASED ON REPETITION

Abstract
The article elaborates the difference between similar lexical and syntactical devices which are based on repetition. Similar and distinctive points of some different rhetoric devices have been studied in the article. Lexical and syntactical devices such as epistrophe or anaphora, mesodiplosis, epiphora, symploce, epizeuxis, parallel construction, reversed construction or chiasmus, antimetabole, anadiplosis, antistasis, negative-positive restatement, diacope and gradatio, epanalepsis have been analyzed respectively. While analyzing the terms which are based on the repetition, it turned out that the major goal of these devices is the emphasis. Despite one common feature, these rhetoric devices and techniques differ from each other for the location along or inside the sentence(s) or clause(s). So some of them are repeated at the beginning of the sentence (epistrophe) while the others are found at the end (epiphora) and in the middle (mesodiplosis) of the sentence or clause. Some are repeated within two or more clauses or sentences in different places.

Keywords: gradatio, antistasis, chiasmus, diacope, mesodiplosis, antimetabole, epanalepsis

Abstract
331 patients with schizophrenia took part in the study: 252 patients with negative symptoms of schizophrenia (main group) and 79 patients with positive symptoms of schizophrenia (comparison group). The research used a comprehensive approach, consisting in the use of psychometric (personal and social functioning scales (PSP)) and statistical research methods. The analysis of the features of social functioning in patients with schizophrenia made it possible to determine that patients with negative symptoms were characterized by the presence of significant violations in socially useful activities and personal and social interaction. In patients with positive symptoms of schizophrenia, significant violations in the field of self-care and in the field of aggressive behavior patterns were noted. The obtained data can be used to create treatment and rehabilitation programs and improve the strategy of psychocorrective care for patients with schizophrenia.

Keywords: schizophrenia, negative symptoms, positive symptoms, social functioning, social interaction, self-care, community service
