Authors: Каберты Нодар Гаврилович , Дзагоев Сергей Федорович
Published: October 2021

Цель работы состоит во всестороннем исследовании показателей уровня жизни населения Республики Южная Осетия как одного из базовых факторов, влияющего на современные и будущие миграционные процессы. Методы. Использованы методы статистического анализа динамики численности и миграции населения Республики Южная Осетия, а также методы компаративного анализа динамики доходов населения в современной Южной Осетии и северокавказских регионах Российской Федерации. Результат. Обоснован вывод о том, что, несмотря на положительную динамику заработной платы работающих в разных отраслях экономики Южной Осетии, доходы работающего населения частично признанного государства пока в разы ниже аналогичных в сопредельных регионах России. Сложившиеся уровень и динамика денежных доходов, выступающие как наиболее интенсивно влияющие на масштабы и направления миграционных процессов обстоятельства, не могут выступать в качестве факторов миграционной привлекательности даже для граждан, покинувших Южную Осетию в ходе осетино-грузинского конфликта 1992–2008 гг. Область применения результатов. Использование полученных результатов в деятельности Правительства Южной Осетии позволит повысить прогностическую составляющую миграционной политики и будет способствовать формированию обоснованных планов социально-экономического развития республики. Выводы. Повышение уровня и качества жизни населения, как минимум, до среднерегиональных показателей Северо-Кавказского федерального округа является для Правительства Южной Осетии приоритетным направлением государственной социально -экономической политики.

End-to-end mapping of a spear-phishing attack on Higher Education Institution in EU
Authors: Nielsen Kurt Gammelgaard , Kristensen Helle Betina
Published: October 2021

Spear-phishing is a growing threat to the education sector. This analysis maps a specific attacker and demonstrate a likelihood 15% to be attacked by this attacker. The analysis uses open source intelligence tools to reveal a continued pattern where the actor is reusing infrastructure and procedure against several HEI in Europe.

For a spear-phising attack to become successful, it has to be able to lure the enduser. This study includes a user vulnerability assessment on the specific spear-phishing attacks used in two comparable studies consisting of 36,851 respondents from two educational institutions. The studies show that without prior training, the concrete spear-phishing attack will lure 20 to 49% of all users.

To investigate the high risk of this attack to endusers an eye-tracking study was conducted. The study shows that respondents generally spend more time viewing phishing indicator than one expect by chance, but there seems to be no correlation between viewing indicators and lured to action. Endusers seems to rate the trustworthiness of mails by an overall reading. As a consequence endusers are easily lured by the attacker because of the trustworthiness of the specific spear-phishing mail.

The Impact of the Pandemic on German Academic IT Facilities in 2020 and beyond. Results of the Annual ZKI Survey on Trends at Academic IT Centres
Authors: Dreyer Malte , Bierwirth Maik
Published: October 2021

Academic IT centres throughout Europe and beyond were affected heavily by the consequences of the Covid-19 pandemic. In particular, teaching services and video conferencing tools had to be significantly enhanced and scaled immediately, while the impact on research IT was moderate, in comparison. In addition, after the Schrems II ruling of the European Court of Justice in July 2020, the situation was further complicated by the fact that the EU-US Privacy Shield was declared invalid. Therefore, tools and services by IT companies based in the US can hardly be used at state-funded universities in the EU without substantial negotiations with the vendors.

A survey across 94 academic institutions in Germany shows which aspects stand out and what priorities many of the German IT centres have set for this sudden, inevitable surge in digitalisation in 2020. The working group on “Strategy and Organisation” of the ZKI Association for German academic IT centres conducts an annual survey on the most important topics and focal points of member institutions. The survey takes up and documents the most relevant or trending issues of IT facilities from universities and research institutions. It is completed by CIOs, heads of data centres, IT directors and persons in comparable roles. The 2021 survey, carried out in December 2020 and January 2021, had an additional focus on the impact of the Covid-19 pandemic on IT institutions in 2020. The results might also shed light on the effects of the pandemic on academic IT facilities in other EU countries – or serve as a basis for differentiation.

Published: October 2021

The campuscloud sciebo is a widely used service for higher education in the federal state of North Rhine-Westphalia (NRW) in compliance with German data protection legislation. The project started in February 2015. Currently, there are over 200.000 registered users. Modernizing the infrastructure for future demands is one of the current major challenges of sciebo. Due to evolved technology, a modernisation of the setup became necessary. Not only for scalability, but also for the closer integration with other services, the shift to a Kubernetes-based platform was an obvious step. Today, the modernized setup consists of two synchronously mirrored server sites, each with a 5 PB net capacity Spectrum Scale file system and two Kubernetes clusters running ownCloud software.

Published: October 2021

Background and Objective: Iron deficiency anemia (IDA) is the most common type of micronutrient deficiency in the world. Numerous reports indicated that adolescence is a period which has an increased risk of development of IDA. Given the importance of IDA and lack of studies in Saravan, a city of Iran, this study was performed to assess the prevalence of IDA among adolescent girls.Methods: In this cross-sectional study, 460 high-school girls were randomly selected. Demographic data was collected using a questionnaire. Knowledge, attitude and practice of participants with regard to iron deficiency anemia was measured at the beginning of the interview. Accordingly, five cc of blood sample was drawn from each student to determine the prevalence of anemia, which was defined by a hemoglobin level lower than 12 mg / dL. The level of ferritin was analyzed to confirm the IDA for students diagnosed with anemia. Ferritin level lower than 12 ?g / dl was considered as IDA. Data was analyzed using SPSS software version 22.Results: Prevalence of anemia and IDA was 24% (n = 111) and 12.6% (n = 58), respectively. Results showed that 37 % of students had good knowledge, 45. 5 % good attitude, and 6.7 % had good practice. Also, there was no significant association between IDA and socio-economic status including parental education, job, and household income (P>0.05).Conclusion: The findings of this study showed that the prevalence of IDA was moderate in Saravan city. Given the importance of IDA and its complications, further studies are needed, especially in high risk populations for IDA such as children.

Background: The biological activities of dark Chinese teas are largely due to their microbial post-fermentation. Herbal teas are traditional Russian beverages that hold special value, owing to their taste and useful medicinal properties. However, no data are available in the literature on using microbial post-fermentation for enhancing their biological activity. The goal of this work was to demonstrate that the fungus Eurotium isolated from Chinese black teas can be used for the post-fermentation of herbal teas produced from bay willow and apple leaves.Methods: Eurotium cristatum was isolated from brick Chinese tea Fujan and identified using conventional methods of microbiology and molecular biology. Low molecular weight metabolites (phenols, amines, sugars, and amino acids) were determined by HPLC. E. cristatum was grown in association with the bacterium Bacillus amyloliquefaciens.Results: It was revealed to exhibit valuable biosynthetic features, such as a lack of mycotoxins, zero antimicrobial activity, and the capacity to synthesize neuroactive amines. B. amyloliquefaciens displayed a wide spectrum of antibiotic (antimicrobial and antifungal) activities that anifested themselves even with antibiotic-resistant bacteria). While growing on green unfermented tea (Camellia sp.) E. cristatum produced and modified neuroactive amines, such as dopamine, serotonin, and epinephrine. The fungus efficiently grew during the post-fermentation of herbal teas from both bay willow and apple leaves. Even though Camellia leaves substantially differed from bay willow and apple leaves in terms of phenol content, the growth of E. cristatum on Camellia was also sufficiently good. This suggests that the growth of Eurotium fungi is not influenced by the phenolic compounds. The data obtained on the composition of phenolic compounds, carbohydrates, and amino acids in the fermented plants and raw material provide evidence that the growth of the fungus proceeds depends on the hydrolysis of high molecular weight phenols and cell biopolymers in the fermented material.Conclusion: Thus, the ability of E. cristatum to grow on plant leaves of significantly different biochemical composition provides foundations for new technologies aiming to obtain post-fermented herbal teas with high biological activity that are enriched in low molecular weight compounds including biogenic amines.
On one approach to the solution of miscellaneous problems of the theory of elasticity

Published: October 2021

Herein, a miscellaneous contact problem of the theory of elasticity in the upper half-plane is considered. The boundary is a real semi-axis separated into four parts, on each of which the boundary conditions are set for the real or imaginary part of two desired analytical functions. Using new unknown functions, the problem is reduced to an inhomogeneous Riemann boundary value problem with a piecewise constant 2 × 2 matrix and four singular points. A diﬀerential equation of the Fuchs class with four singular points is constructed, the residue matrices of which are found by the logarithm method of the product of matrices. The single solution of the problem is represented in terms of Cauchy-type integrals when the solvability condition is met.
Eigenvalues, traceability, and perfect matching of a graph
Authors: Benediktovich V. I.
Published: October 2021

It is well known that the recognition problem of the existence of a perfect matching in a graph, as well as the recognition problem of its Hamiltonicity and traceability, is NP-complete. Quite recently, lower bounds for the size and the spectral radius of a graph that guarantee the existence of a perfect matching in it have been obtained. We improve these bounds, ﬁrstly, by using the available bounds for the size of the graph for existence of a Hamiltonian path in it, and secondly, by ﬁnding new lower bounds for the spectral radius of the graph that are suﬃcient for the traceability property. Moreover, we develop the recognition algorithm of the existence of a perfect matching in a graph. This algorithm uses the concept of a (κ,τ)-regular set, which becomes polynomial in the class of graphs with a ﬁxed cyclomatic number.
Deformed and stressed states of materials at the rolling of three layer stacks, dislocation structure of inner layer – nickel foil
Authors: Hurski L. I.
Published: October 2021

The deformed and stressed states during rolling of a three-layer stack from various materials with a nickel foil inner layer are considered. The technique of determining the density of dislocations is described. The data about the inﬂuence of deformation conditions on the distribution and density of dislocations during rolling of nickel foil in various stacks are presented, including the registration or determination of the dislocation structure of nickel foil before deformation and at various degrees of deformation. It is shown that the mechanical scheme of deformation of the inner layer of the stack, namely, the deformation of the nickel foil by non-uniform compression with shear, has a decisive inﬂuence on the development of the dislocation structure and properties. It is established that the dislocation density is determined not only by the degree of deformation, but also by a scheme of the deformed and stressed state of matter, and for the case of shear deformation with increasing degree of deformation the dislocation density increases more rapidly than in the case of tensile strain or compression without shear; the result of shear deformation is a signiﬁcant reﬁnement of the structure of materials: with increasing degree of plastic deformation of the material a three-dimensional cellular network of dislocation is formed, wherein the borders of cells are formed by tangles of dislocations. With increasing degree of deformation, the density of dislocations at the cell boundaries increases, and the size of the cells decreases; in this case, the areas inside the cells of the dislocation network are always free of dislocations. The obtained results allow recommending the schemes with shear deformation for new promising processes of production of materials with unique properties.

The article deals with the choice of materials for connecting tires of traction batteries (TB). The optimal parameters of their spot welding with batteries are experimentally established (the ﬁrst pulse with a current of 7 kA duration of 1 ms, the break between the pulses of 1 ms, the second pulse with a current of 7 kA duration of 2 ms). When operating the traction battery on electric vehicles, the resistance of the connecting tires should not lead to heating of the batteries in order to avoid overheating above 60 °C. In most modern TB, consisting of Li-ion elements, a nickel tape is used for the connection. To ensure the weldability of materials (copper–nickel or nickel–nickel), it is important that the operating temperature is reached at a short-term current pulse in the welding zone. One of the solutions to this problem is the application of a metal coating. Experiments were conducted on the weldability of various materials, including those with applied coatings. The best results in weldability were shown by tires made of tinned copper, which was welded to nickel plates (emitting the battery body). Tear tests of the welded samples were carried out. The tensile strength of the original copper tires was 340–450 MPa. When welding copper–nickel and copper(tinned) – nickel plates, the strength limit values reach 70 % of the strength of the original copper plate. On the basis of the obtained experimental data, a pilot batch of battery TB was manufactured, which successfully passed tests for compliance with the technical requirements for the strength and the value of the transition resistances of the welded joints of connecting buses with batteries.
Improved model of powder blend compacting in a roll compactor

A new mathematical model of mineral fertilizer compacting using a roll compactor is developed. This model is based on the transition to the values of stress tensor components averaged over the cross-sectional area of the powder mixture ﬂow. To deﬁne these stresses, equations of equilibrium of the elementary layer determined in the mixture by two planes perpendicular to the ﬂow direction are composed. To obtain relatively simple analytical relations in the calculations, the hypothesis of a power-law dependence of hydrostatic pressure on mixture density, accepted in the framework of the Johansen model, was used. In order to take into account changes in the mechanical characteristics of the mixture (angle of internal friction, coefﬁcient of external friction, transverse strain coefﬁcient) while compacting, we approximated the known experimental dependencies of the corresponding characteristics on the density. The inter-particle cohesion parameter was taken to be proportional to the hydrostatic pressure. The model allows calculating the gap between the rolls surfaces for a given initial bulk density and the required ﬂake density. With the known gap value, the distribution of the axial average stresses in the powder mixture, the normal and shear stresses on the rolls’ surfaces are determined. The results of the calculations of the rolls surface gap and the normal roll pressure diagram are compared with the experimental data given in the literature for the urea compacting process.
Surface construction for orthrotropic perfectly elastic-plastic Murnaghan material
Authors: Shved O. L.
Published: October 2021

The problem of constructing a yield surface is described. The magnitude of the stress velocity potential is explained graphically. The parameters of an elastic-plastic process are introduced: a modiﬁed R. Schmidt parameter and an analogue of the Lode parameter, the sign of which changes only when the singular point of the plasticity curve passes. The formal work area of the Murnaghan law is calculated, the real area will be much smaller. An effect similar to the Bauschinger effect for the deviator of the stress tensor is assumed to be fair. In the basic experiments of uniaxial and biaxial tension, compression and shear, a piecewise-linear generator with vertices at the corresponding singular points of the plasticity curves is determined. The magnitude of the effect is approximated by a quadratic dependence in the place parameter and piecewise-linear one in the hardening parameter. According to the magnitude of the effect, at the point of the active process there is a singular point of the curve, into which the basic generator moves. The yield surface is constructed by ductility curves drawn through the generator. Determination of the magnitude of the effect under repeated loading after unloading is considered.

By scanning the blades of the impeller and the guide devices of the full-scale compressor of the helicopter gas turbine engine, a solid-state design model of the compressor with a tunable geometry in the height of the blades was developed. The empirical dependencies of the values of nonlinear wear of the blade of the 1st stage of the compressor on the operating time and the concentration of dust in the air are presented. A block diagram of the procedure for calculating the characteristics and parameters of a helicopter gas turbine compressor is presented. When calculating the ﬂow in the gas–air path of the compressor, the numerical solution of the Navier–Stokes equations averaged by Reynolds, the ﬁnite element method in combination with the establishment of patterns of erosive wear of the blades depending on the operating conditions of the engine is used. Mathematical dependencies of the thermogasodynamic parameters of the helicopter gas turbine compressor operation on its operating time and the dustiness of the atmosphere are obtained using modeling. The obtained results can be used in the development of a methodology for automated monitoring of the wear condition of the compressor blades of a helicopter gas turbine engine according to its thermogasodynamic parameters, applied to various climatic operating conditions.
