The stress-migration phenomenon in films of alloy Al–Si which is observed at a current of high density (an order 105 А/mm2) is investigated. By results of researches the technical decision which allows quality raise of obtained film structures is offered. Its essence consists in formation in films the traps for migrating atoms of aluminium at course of a current of high density at the expense of formation the passive layer of TiN on the metal layer surface, for example, Al–1,5 %Si. In the presence of advanced relief of a surface of modern integrated circuits, for example with sub-micron sizes of the topology elements, the thickness and structure of metal current-carrying films on relief steps differs from what are located on planar sites. It leads to occurrence of essential gradients of mechanical pressure which are stress-migration motive power. As it is known, that temperature factor of linear expansion of aluminium is approximately 20 times, than SiO2, that causes active generation of dot defects in a layer of the alloy on the base of aluminium which is much more plastic than SiO2. Under the influence of a gradient of residual pressure, dot defects, existed in films, for example vacancies, come to movement mainly on border of metal - dielectric and in due course under the influence of a current of high density lead to formation of group defects in an alloy film, in particular emptiness, hills etc. Since stress-migration processes on these sites occur most intensively, as a result there is a rupture of films mainly on steps of a topological relief. Results of the research have passed approbation and can be used at manufacturing of silicon semi-conductor devices and integrated microcircuits.

Introduction. The article is devoted to the analysis of the linguistic means expressing the concept of «mystery» in the fictional works of J. Lippard and N. Buntline, the allocation of its socio-cultural component and the field model construction of lexical units representing this concept. The relevance of the research is due to the interest of modern linguistics in the study of the conceptual sphere of artistic works of the «urban mysteries» genre by American authors.Methodology and sources. The study was conducted within the framework of a linguistic and cultural approach using methods of description, comparison, interpretative analysis, conceptual analysis, the method of dictionary definitions analyzing, structural and semantic analysis, and the method of quantitative calculations. The illustrative material of the study consisted of more than 74 lexical units representing the «mystery» concept in the language, 45 of which were found in the analyzed works. The material was obtained by the method of directed sampling from the fictional works of American authors of the 19th century.Results and discussion. This article discusses and analyzes various interpretations of the concept of «mystery» by domestic and foreign scientists; defines the role of the concept in the work of fiction as a whole and in the analyzed novels of two authors J. lippard and N. Buntline; identifies the features of the linguistic implementation of the «mystery» concept; classifies the linguistic units of the concept according to their parts of speech, semantics and stylistic coloring; analyzes the writers' linguistic pictures of the world and the conceptual sphere of their works, the illustrative zone of which reveals the reasons for the similarity not only of the storylines of the works, but also of their lexical content.Conclusion. The study made it possible to describe and illustrate the individual style of American authors of the 19th century through a system of expressive means that correlates the inner world of the writer with the artistic reality, the artistic world of the text created by the «poetic» language. The mental world can be interpreted in cognitive terminology as an individual poetic conceptual sphere, or the conceptual system of the author, consisting of a conceptual, objective, associative, figurative and symbolic layer of the concept. The study showed that the learning of the writer's linguistic picture of the world and the conceptual sphere of the work can be carried out using a field model, analyzing the LSF forming the «mystery» concept. The analyzed LSF is distinguished by a more specific vocabulary composition, the complication of the seme structure of words, the seme expansion and the restructuring of their hierarchy, which together form the artistic worldview of the authors.

After strong earthquakes and volcanic eruptions, geomagnetic oscillations with frequencies of 3.5–4.0 mHz have sometimes been observed. In this paper, we theoretically study the probable cause of these phenomena, which is related to the vertical acoustic resonance arising between the Earth's surface and the thermosphere due to the propagation of the atmospheric wave corresponding to the acoustic branch generated by surface displacements. In the plane layered model of the atmosphere and ionosphere with inclined geomagnetic field, we analyze the propagation of two-dimensional (2D) harmonic acoustic wave. The height of the reflecting atmospheric layer corresponds to the region of sharp temperature change close to the thermosphere boundary ∼80–90 km. In this case, the calculated fundamental resonant frequency is close to the frequencies of the observed oscillations. The solution of this problem is used to calculate currents and electromagnetic perturbations in the atmosphere and ionosphere. The ionospheric E-layer is considered in the thin layer approximation. In this approximation, the formulas describing the geomagnetic perturbations (GMP) in the ionosphere and on the Earth's surface are derived. The GMP spectrum contains a sharp maximum at the frequency corresponding to the acoustic resonance. According to the calculations, close to the resonance frequency, the spectral powers of GMPs on the ground can reach 5–30 nT2/Hz, which is consistent with the results of ground-based measurements.

The article deals with the phenomenon of tattooing practices, its functional significance and role in everyday communications. As an empirical object of research, we chose urban youth aged 18-25 years old, who has 3 or more tattoos and lives in Novosibirsk. We also used quantitative secondary data obtained as a result of the VTsIOM study to justify the choice of an empirical object, as well as to describe the attitude of different age groups to practices tattooing. Twenty-six semi-structured interviews were conducted. During the analysis of the information received, we were able to discover the functional significance of tattoos in the life of urban youth, describe the features of making a decision about a tattoo, and identify the role of tattoos in the process of everyday communication.

The article examines Russian-Chinese relations in the context of the interface between the projects of the Eurasian Economic Union and the project "One Belt — One Road." For a relatively long time, experts considered the difficulty of connecting these projects. The EAEU is an integration association of some countries of the post-Soviet space. Regarding the economic belt of the Silk Road, there has long been a discussion about its essence and mechanisms. The complexity of the interface was seen in the obvious difference in the essence of the projects, and hence the interface mechanisms themselves. The concept of "One Belt — One Road" is used by us as a generalization for all individual projects put forward by the People's Republic of China. In fact, this does not change the interface problem. Recently, with the emergence of new views on integration issues and the formation of the theory of Eurasian integration, it became possible to consider it as a certain mechanism for achieving other more significant goals.Aim. The purpose of the study is to analyze Russian-Chinese relations in the context of the impact of the development of integration projects of EAEU and OBOR.Tasks. Thus, the tasks of the study were: to show the possibility of studying the interaction of projects within the framework of integration interaction; show that interaction is a mechanism for influencing Russian-Chinese relations.Methods. The research methodology is based on modern views on the process of Eurasian integration, more precisely on such concepts as "pragmatic Eurasianism," "securing integration," "geographical poles of inaccessibility," "transport union." At the same time, the main idea is integration as a mechanism for achieving other goals, including the possibility of influencing international relations. Under current circumstances, the COVID-19 pandemic has a direct impact on international relations and in particular on international economic relations. Since the modern development, primarily economic relations, is largely determined by the influence of the pandemic, the secondary task was to show the stability of integration associations to the conditions of the pandemic.Results. The results were: the possibility of using the provisions of the modern theory of Eurasian integration to solve the problems of interaction between the EAEU and the OBOR was shown; it is shown that the ideological contradictions of the projects of the EAEU (protection of preferences of the common customs territory) and the OBOR (creation of extensive FTAs) are partially removed by the signed agreements within the framework of the interface; resistance of integration structures to pandemic is shown.Conclusions. New approaches to defining the integration process, in particular, the theory of Eurasian integration — "pragmatic Eurasianism" is focused on the possibility of achieving the goals of the "One Belt — One Road" project and the concept of the Great Eurasian Partnership and provides an opportunity to show the dynamics of development, including in Russian-Chinese relations.

The article presents an analysis of literature data and the results of our own retrospective studies of the characteristics of the menstrual cycle in female combatants who have undergone concussion. Clinical and anamnestic factors have been identified that negatively affect the menstrual function of women of reproductive age, who received contusions during hostilities. The relationship between the state of mental health of women and menstrual irregularities has been established. Aim: to identify and evaluate changes in the menstrual function of women - veterans of reproductive age. Also, to establish the relationship between menstrual irregularities in women - veterans of reproductive age who have undergone contusion, and the state of their somatic and mental health.Materials and method: The research was conducted at the Department of Obstetrics, Gynecology and Reproductology of the National University of Health of Ukraine named after P.L. Shupika. To achieve this goal, a comprehensive clinical and laboratory examination was performed in 567 women of reproductive age (main group and comparison group) who participated in hostilities and suffered contusions, the average age of the subjects was 27.08 ± 4.23 years.The period of stay in the combat zone is 29.34 ± 9.21 months, the time from the moment of receiving a mild traumatic brain injury (contusion) is 18.8 ± 9.2 months. Group I - 399 fertile women who suffered contusions during the fighting with PKS. Group II - 168 women of childbearing age who suffered contusions during hostilities without PKS (mean age 32.21 ± 7.32 years).Results: The results of the studies revealed statistically significant deviations in the characteristics of the menstrual cycle of women who participated in hostilities who were injured with PKS, compared with women without PKS. It has been proven that women-viskovosluzhvits more often develop menstrual irregularities, namely a decrease or increase in the number, lengthening or shortening of the menstrual cycle by 7 days. Taking into account ...

The article analyzes specific elements of the Arab societies' political life which distinguish it from political relations in the Western nation-states. Admitting the existence of a large number of such kind of elements, the authors focus only on three of them which are related to the sources of power and its distribution. Emphasizing that these elements are deeply rooted into the Arab-Muslim political tradition, so that they have tended to be present throughout the whole Islamic period of the region, the authors find out that each of them has its own medieval countertype. Thus, the article addresses the dichotomy of the supreme power of caliphs and sultans, formed in the IX – XI centuries and manifested today both in Jihadist organizations (i.e. ISIS, Al-Qaeda) and in the political strategies of moderate Islamist movements, such as Tunisian party Al-Nahda. The second example is the urban militias, which are correlated with the medieval phenomenon of «young hero» or «chivalry» communities – fityan. The fityan communities have seven specific traits, which not only are characteristic of the militias, but also demonstrate fundamental difference between the militias and urban criminal groups. Major attention is paid to Libyan militias, which are studied on the materials of field research conducted by one of the authors. Finally, the third element discussed is the particular role of the army and other security forces in the Arab political systems.The authors provide three possible interpretations of all the revealed coincidences. According to the first one, they are presented as aberrations of the researcher's scientific consciousness, which make them look for historical equivalents to contemporary issues. Second interpretation belongs to the tradition of «the new medievalism». According to it, the described phenomenon is in fact the revival of some medieval practices, caused by the end of the Modernity era. The last interpretation views the analyzed elements as distinctive civilization traits of the Arab world.
