Evaluation of Shear Strength Parameters in Unreinforced and Shotcrete Reinforced Coal through Experimental and Numerical Methods
Authors: Bhat Ilyas , S. Rupali , Kumar Arvind
Published: August 2022

The shear strength of coal mines forms the most significant aspect in the evaluation of mining disasters. A series of direct shear strength tests were conducted on intact coal specimens and coal-shotcrete specimens to evaluate the shear strength characteristics of the coal and coal-shotcrete interface. The tests were carried out under 1, 2 and 3 MPa of normal pressure respectively. The peak shear strength in intact coal specimen reaches its maximum value of 3.96 MPa under 3MPa of normally applied pressure while the shotcrete-coal interface has an estimated peak shear strength of 0.73, 0.80 and 0.86 MPa under the normal pressure of 1, 2 and 3 MPa respectively. Mohr-Coulomb model parameters such as adhesion strength and angle of adhesion were further determined that were used for the design and evaluation of shear strength of in situ coal mines. Numerical simulations of coal-shotcrete and intact coal specimens were performed using the Mohr-Coulomb model in Abaqus software and the numerical results obtained were found in good agreement with experimental results exhibiting peak variation of less than 15%. Further, ultrasonic pulse velocity test measurements were performed on coal specimens to evaluate the dynamic shear strength parameters and the parameters obtained were found to be enhanced compared to static strength parameters.
Evaluation of Doppler and electroencephalographic changes in patients with postconcussion syndrome due to mild blast traumatic brain injury
Authors: Tretiakova Albina I. , Zavaliy Yurii V.
Published: August 2022

Mild blast traumatic brain injury (mbTBI) often remains undiagnosed and untreated due to lack of treatment of patient, imperfect screening tools, unclear diagnostic criteria, and lack of means to objectify or visualize the injury.
Objective: to investigate Doppler and electroencephalographic changes in patients with postconcussion syndrome (PCS) due to mbTBI and the possibility of their use to objectify the injury.
Materials and methods. The study involved 115 male participants of hostilities in the East Ukraine (main group) with a diagnosis of "PCS after previous mbTBI" and 30 healthy individuals (control group). Patients were in the long-term period of injury (from 6 months to 3 years). After collecting complaints and history data, the neurological status and the state of cognitive functions were examined. Neuropsychological testing according to the Montreal cognitive assessment score was carried out. Ultrasound duplex scanning with color Doppler mapping of neck and head vessels and transcranial duplex scanning were performed. Quantitative electroencephalography was performed according to standard parameters (sensitivity - 70 μV / cm, time constant - 0.1 s, filter - 40 Hz).
Results. In patients with PCS after mbTBI, transcranial duplex scanning can detect changes in vascular resistance in the intracranial vessels of both the carotid and vertebrobasilar basins (mostly reduced resistance values), as well as signs of venous discirculation in the basal veins of the brain, quantitative electroencephalography – changes in the frequency and topic of the α-rhythm, a decrease in its amplitude, frequency-spatial inversion, the presence of signs of dysfunction of nonspecific brain structures, according to spectral analysis – a decrease in α-power, an increase in β-power, activity in θ- and δ-bands.
Conclusions. Detected Doppler and electroencephalographic changes may persist in the long-term period of mbTBI. They should be taken into account in the differential diagnosis of post-traumatic stress disorder.

Published: August 2022

Objective: The spinal accessory nerve (Acc) is susceptible to trauma in at least 6% of cases of brachial plexus injury (BPI). The impaired Acc function disables its utilization for transfer to the suprascapular nerve (SS). The selection of approach to SS is highly dependant on the anatomy of BPI. The purpose of this study was to determine the incidence of the anterior-posterior approach of Acc to SS transfer in BPI and associated functional outcomes.
Methods. Twenty nine patients with BP/Acc associated injury were included. Ten patients underwent the transfer of Acc to SS by the anterior approach (AA), 19 patients – by the posterior approach (PA). Nine nerve transfers through AA and one nerve transfer through PA required the interposition of an autologous nerve graft. The functioning of the supra-/infraspinatus muscle was evaluated at 9 and 15mos. on the basis of the MRC and the external rotation (ER) range. ER more than +400 beyond the sagittal plane was regarded as effective recovery of function.
Results. Impaired function (M3 or lower on MRC) of the lower trapezius muscle was associated with preserved anatomy of the SS in the supraclavicular region in 9 out of 10 cases. Eighteen patients (62%) recovered to M3 and higher (shoulder stability), 11of these (38%) showed recovery to M4-M5. Five of all patients recovered to M4-M5 and were able to produce ER within the effective ROM (+400-600 of ER). After the AA to the SS, shoulder stability was restored in 60% of cases (M4-M5 in 30%). After the PA to the SS, shoulder stability was restored in 74% of cases (M4-M5 in 42%). Only non-complete BPI showed effective recovery of power and function in terms of less than 6 mos. after injury. PA to SS with no graft provided shoulder stability in 72% of cases, AA to the SS and the graft interposition ensured shoulder stability in 50% of cases.
Conclusions. The incidence of AA to the SS was 35%, PA – 65%; preserved anatomy of the SS in supraclavicular region was associated with an increased risk of trapezius muscle dysfunction; the PA to SS and consecutive direct end-to-end transfer of Acc showed better results compared to other combinations of nerve transfers in providing shoulder stability.

Published: August 2022

Many soldiers who were wounded during the war in Ukraine with Russia increased the number of cases of spinal injury.
As a result of the Russia-Ukraine war, the number of patients with spine and spinal cord injuries increased significantly.
According to the literature, gunshot wounds to the spine and spinal cord accounted for 0.26% of all soldier injuries during the American Civil War, with a mortality rate of 55%. According to the U.S. military data, spinal and spinal cord injuries accounted for 1.2% of war-related deaths during the Korean War, 1.0% - during the Vietnam War and the Gulf War, 6.0% - during the US invasion of Panama, 11.1% - during the war in Afghanistan and Iraq. Disability related to spinal cord injuries (14.0%) is currently the leading cause of discharge from military service for U.S. soldiers who have been injured.
Patient M., 32 years old, male sustained mine blast injury. Immediately after the injury there was tetraplegia.
Surgery was performed to correct vertebrae С7–Тh1, decompression of the spinal cord at the level of vertebrae С7–Тh1. Sixteen days after surgery, the neurological deficit regressed to the Frankel C clinical group. The patient was transferred to rehabilitation treatment.
A clear, consistent, rapid algorithm of action in spinal cord injuries allowed to provide highly qualified care, which allowed to achieve significant results in the regression of neurological deficits in the postoperative period.

Published: August 2022

Oriented attachment of nanobricks into hierarchical multi-scale structures such as inorganic nanoclusters is one of the crystallization mechanisms that has revolutionized the field of nano and materials science. Herein, we show that the mosaicity, which measures the misalignment of crystal plane orientation between the nanobricks, governs their magneto-optical properties as well as the magnetic heating functions of iron oxide nanoclusters. Thanks to high-temperature and time-resolved microfluidics, we were able to isolate and characterize (structure, properties, function) the different intermediates involved in the diverse steps of the nanocluster’s formation, to propose a detailed dynamical mechanism of their formation and establish a clear correlation between changes in mosaicity at the nanoscale and their resulting physical properties. Finally, we demonstrate that their magneto-optical properties can be described using simple molecular theories.
Towards predictive design of electrolyte solutions by accelerating ab initio simulation with neural networks.
Authors: Zhang Junji , Pagotto Joshua , Duignan Timothy
Published: August 2022

Electrolyte solutions play a vital role in a vast range of important materials chemistry applications. For example, they are a crucial component in batteries, fuel cells, supercapacitors, electrolysis and carbon dioxide conversion/capture. Unfortunately, the determination of even their most basic properties from first principles remains an unsolved problem. As a result, the discovery and optimisation of electrolyte solutions for these applications largely relies on chemical intuition, experimental trial and error or empirical models. The challenge is that the dynamic nature of liquid electrolyte solutions require long simulation times to generate trajectories that sufficiently sample the configuration space; the long range electrostatic interactions require large system sizes; while the short range quantum mechanical (QM) interactions require an accurate level of theory. Fortunately, recent advances in the field of deep learning, specifically neural network potentials (NNPs), can enable significant accelerations in sampling the configuration space of electrolyte solutions. Here, we outline the implications of these recent advances for the field of materials chemistry and identify outstanding challenges and potential solutions.
Catalytic enantioselective 6𝝿 photocyclization of acrylanilides
Authors: Jones Benjamin , Solon Pearse , Popescu Mihai , Du Ji-Yuan , Paton Robert , Smith Martin
Published: August 2022

Controlling absolute stereochemistry in catalytic photochemical reactions is generally challenging owing to high rates of background reactivity. Successful strategies broadly rely on selective excitation of the reaction substrate when associated with a chiral catalyst. Recent stud-ies have demonstrated that chiral Lewis acid complexes can enable selective energy transfer from a photosensitizer to facilitate enantiose-lective triplet state reactions. Here, we apply this approach to the enantioselective catalysis of a 6π photocyclization through the design of an iridium photosensitizer optimized to undergo energy transfer to a reaction substrate only in the presence of a chiral Lewis acid complex. Amongst a group of iridium(III) sensitizers, enantioselectivity and yield closely correlate with photocatalyst triplet energy within a narrow window enabled by a modest reduction in substrate triplet energy upon binding a scandium/ligand complex. These results demonstrate that photocatalyst tuning offers a means to suppress background reactivity and improve enantioselectivity in photochemical reactions.
Modeling coarse-grained van der Waals interactions using dipole-coupled anisotropic quantum Drude oscillators
Authors: Bandyopadhyay Prasanta , Sadhukhan Mainak
Published: August 2022

The Quantum Drude Oscillator (QDO) model is a promising candidate for accurately calculating the van der Waals (vdW) energies. Anisotropic QDO models have recently been used to represent molecular fragments rather than single atoms. While this model promises accurate calculation of vdW energies, there is significant room for improvements such as incorporating a proper fragmentation method, higher-order dispersion corrections, etc. The present work attempts to gauge dipole-dipole interactions’ ability without fragmentation. A suitable anisotropic damping function is also introduced to work with anisotropic QDO. This revised model accurately predicts the vdW complex for the majority of the systems considered. This work indicates the limit of dipole approximation for an anisotropic QDO-based model.
Understanding activity trends in furfural hydrogenation on transition metal surfaces
Authors: Liu Sihang , Govindarajan Nitish , Chan Karen
Published: August 2022

Furfural hydrogenation to furfuryl alcohol is an industrially significant reaction for biomass valorization. The hydrogenation process has been mainly catalyzed by chromite-based materials that are notorious for their toxicity, thereby highlighting the need to find alternate catalyst materials. In addition, there is a gap in the mechanistic understanding of furfural hydrogenation on transition metal surfaces. Herein, we combine density functional theory calculations and microkinetic modeling to study the reaction mechanism of furfural hydrogenation to furfuryl alcohol on terrace (111/0001) and stepped (211) transition metal surfaces. We find the rate- determining steps for furfural hydrogenation to depend on the identity of the metal, where the strong binding metals are limited by desorption of the product (furfuryl alcohol) while the moderate and weak binding metals are limited by steps involving surface hydrogenation or H2 activation. We show that the binding energy of furfural is a good descriptor to rationalize and predict the activity trends for the production of furfuryl alcohol. Among the metal and bulk/single atom alloy surfaces investigated in this work, we find Cu-based alloys to be the most active catalysts, with CuNi alloys predicted to be promising candidates for furfural hydrogenation.

Recently, various metabolites derived from host microbes have been reported to modulate the immune system, with potential involvement in health or diseases. Archaea, prokaryotic organisms, are present in the human body, but their connection with the host is largely unknown when compared with other microorganisms such as bacteria. This study focused on unique glycerolipids from symbiotic methanogenic archaea and evaluated their activities toward an innate immune receptor. The results revealed that archaeal lipids were recognized by the C-type lectin receptor Mincle and induced immune responses. A concurrent structure-activity relationship study identified key structural features of archaeal lipids required for recognition by Mincle. Subsequent gene expression profiling suggested qualitative differences between the symbiotic archaeal lipid and the pathogenic bacteria-derived lipid. These findings have broad implications for understanding the function and pathogenicity of symbiotic archaea to host health and diseases.
Kinetic energy density for open-shell systems: Analysis and development of a novel technique
Authors: Priya Priya , Sadhukhan Mainak
Published: August 2022

The quest for an approximate yet accurate kinetic energy density functional is central to the development of orbital-free density functional theory. While a recipe for closed-shell systems has been proposed earlier, we have shown that it cannot be naively extended to open-shell atoms. In this present work, we investigated the efficacy of an ad-hoc recipe to compute the kinetic energy densities for open-shell atoms by extending the methodology used for closed-shell systems. We have also analyzed the spin-dependent features of Pauli potentials derived from two previously devised enhancement factors. Further, we have proposed an alternate but exact methodology to systematically compute the kinetic energy density for atoms of arbitrary spin multiplicity.
Paisajes de Aprendizaje: infraestructura educativa para personas con déficit auditivo
Authors: Neuhaus Buzaglo Carolina Lucía
Published: August 2022

Al tratar sobre la deuda de infraestructura educativa, se suele hacer hincapié en el déficit cuantitativo; sin embargo, poco se habla de cómo se proyectan las escuelas. Este artículo expone la toma de partido y las estrategias de mi proyecto de fin de carrera “Paisajes de aprendizaje” (2019), donde se plantea el diseño de una escuela inclusiva para personas con déficit auditivo. Para esto, se enfoca en dos cuestionamientos fundamentales: ¿cómo proyectar para resolver las necesidades de los niños no oyentes? y ¿cómo resolver el problema de las barreras que limitan la accesibilidad en nuestras ciudades? En este aspecto, el aprendizaje corporal, el auto descubrimiento y los estímulos hápticos son los lineamientos básicos de diseño. Por medio de este, se cuestionan los límites de accesibilidad al interior de la ciudad, haciendo del entorno el medio conector entre el espacio público y la ciudad, entre una población minoritaria y la sociedad.
Patrimonio invisible. Un estudio en México con personas de diversidad funcional visual sobre accesibilidad al patrimonio edificado
Authors: Gómez Casanova Mireya , Pérez Barragán Martha Yolanda , Azevedo Salomao Eugenia María
Published: August 2022

La diversidad es una variable transversal en todos los campos, que debe ser considerada a través de la accesibilidad universal. Ni las zonas urbanas históricas ni el patrimonio edificado tienen que ser excepciones para incluir a la diversidad en su gestión. Pero ¿cómo se consolida una perspectiva de diversidad funcional en el campo cultural patrimonial? Se propone una reflexión sobre la relación que se construye entre patrimonio y sentidos a través de la experiencia de personas con limitación visual, quienes no pueden establecer una relación persona-edificio de una manera visual y recurren a otros campos perceptivos. Tal reflexión permite ampliar las posibilidades para el conocimiento del patrimonio desde el enfoque de la conservación activa, reforzando la idea de conocer para valorar y, en consecuencia, conservar. Desde este enfoque, el patrimonio es visto no como remanente del pasado, sino lleno de futuras posibilidades y, sobre todo, como una presencia actual.

In the present world of technology, students grow up with technological devices at home and in schools, which revolutionize the way they learn. Future education technology shall transform teaching and learning by providing teachers and students with a variety of new devices to work with. Thus, the study was designed to examine the impact of multimedia technology-integrated instruction on learning satisfaction of students studying at upper primary level in one of the countryside primary schools in Bhutan. A mixed methods research was adopted to ensure better understanding of the results. Following a purposive sampling technique, 45 students were selected as research samples. Over a period of three months, the participants were taught at least three lessons of science in a week using multimedia technology. Instruments such as open-ended questions and questionnaires were administered to assemble the data. The quantitative data collected from the questionnaire were analyzed and inferred using the inferential statistical t-test with significance p<0.05 and descriptive statistical mean and standard deviation. And qualitative data from open-ended questions were analyzed using the grounded theory coding system. The findings revealed that students were highly satisfied with learning science through multimedia technology, as it not only made the lessons easier to understand and lively to participate in, but also challenging and enjoyable. Furthermore, inferential statistics revealed that there was no statistically significant difference in satisfaction with learning between male and female students. Therefore, the researchers stipulated that the integration of multimedia technology assisted instruction had a large positive impact on increasing student learning satisfaction. The findings of this study were intended to inform curriculum reformers, educational leaders, and teachers with practical evidence that they should propose pedagogical change in classroom teaching and learning using multimedia technology.

Authors: Almutairi Nouf Rashdan
Published: August 2022

The current study aimed to investigate the extent and areas of training needs of teachers of students with learning disabilities (LD) as well as the extent to which some demographic variables influence the training needs for LD teachers. The researcher adopted a quantitative research method using a 42-item questionnaire as a data collection tool. The sample consisted of 432 LD teachers working in the programs designed for LD students in public schools in Riyadh. Teachers were selected using the simple random sampling method. The data were analyzed using descriptive and inferential statistical techniques. The results indicated that the most of the questionnaire items represented moderate training needs (mean = 2.78) for the teachers. The results indicated that, to a certain extent, gender influenced the extent of training needs of teachers working with LD students. For example, male teachers had more training needs than female teachers. Qualification and years of teaching experience were found to influence the training needs of participants in this study, for example, teachers with bachelor’s degrees were found to have more training needs than those with master’s degrees, while those with less than 5 years of experience have more training needs comparing to other groups. Implications and recommendation for designing LD teachers’ professional development programs are discussed.

It is proposed to implement pedagogical practices in various forms from the first year of study in a higher education institution, combining practical, educational and cognitive, research activities, using the results obtained in course and qualification projects, individual educational and research tasks from the cycle of disciplines.
PIER PAOLO PASOLINI AND CONTEMPORARY ITALIAN LITERATURE
Authors:   Russian State University for the Humanities, Bystrova Tat’yana A.
Published: August 2022

The article is concerned with the perception of Pasolini’s works and ideas in the contemporary Italian literature. Many modern writers mention or refer to Pasolini in their works. For some of them he is a brilliant rebel of the 1970s (Elena Ferrante), others are still shocked by his death (Andrea Baiani), some turn to his literary heritage, borrowing individual ideas and images (the idea of Post-history cited by Antonio Scurati, the theme of duplicity by Sandro Veronesi, the theme of consumerism in modern society by Walter City) or echo by the very structure of their works (Giuseppe Genna). Pasolini becomes an example or a beacon for many modern writers, he is seen as a man who is undividedly devoted to the word and at the same time has a clear ideological position, who put above all the needs of his neighbors and who took on himself the role of the national conscience revealing the ills of modern society.
ABOUT SOME FEATURES OF LEONID ARONZON’S ARTISTIC WORLD
Authors:   Russian State University for the Humanities, Pronin Maksim V.
Published: August 2022

The article analyses some features and variations of the use of various means of poetic language in the work of the Soviet uncensored poet Leonid Aronzon (1939–1970). Even despite the fact that most of his poems were written in accordance with all the norms of traditional syllabic-tonic versification, the author in his texts actively experiments with the use of certain means of language, exercises in the word and form creation, often creates new words and various sentences, devoid of a semantic layer, uses borrowings from foreign languages, ready-made quotations from other literary works, abusive or obscene vocabulary that is not recognized as the norm of the literary language, adapts phrases and other components of syntax to foreign or Russian forms. In some cases, he also experimented with visual poetry, non-standard graphic presentation of the text, trying to achieve, as far as possible, its ideal symmetry in writing. The examples of the use of certain means of poetic language considered in this article, their definition and systematization, allow the reader to better understand how the artistic world of the author works.
THE INFLUENCE OF MODERN TRENDS ON THE SPECIFICS OF THE SUBJECTIVE ORGANIZATION OF ROCK TEXTS OF THE 21ST CENTURY
Authors:   Russian State University for the Humanities, Solntseva Arina Yu.
Published: August 2022

The article studies the influence of modern trends on the specifics of the subjective organization of rock texts of the musicians generation in the “pro-Western” period, starting from that of the “era” of the emo subculture and ending in 2021. The main purpose of the article is to establish the peculiarity of the subjective organization of texts in rock poetry of the 2000s–2010s, as well as to determine the influence of social events on the change of the lyrical hero. In the course of the study, conclusions are drawn about the importance of the performer in the communicative chain “author-hero-performer-audience”, as well as possible reasons for changing the characteristics of lyrical heroes in the texts of four Russian rock bands of the modern generation (“Tracktor Bowling”, “Louna”, “Amatory”, “Pornofilms”). Using the example of the texts of each of these groups, the conclusion is made about a certain development of the group from the beginning of the creative path to its end or the last album as well as about the importance of the performer’s role for the texts composition of modern performers, as well as about the mutation of the lyrical hero under the influence of extra-textual factors. The article discusses the common features of the subject organization of four groups created at different times and having different communicative goals. Based on the subjective analysis, a conclusion is drawn about the mass character of modern rock music.
THE “BLACK LEGEND” ABOUT VALENTINA VISCONTI IN THE FRENCH POLITICAL CULTURE AT THE TURN OF THE 14TH–15TH CENTURIES
Authors:   Institute of World History, Togoeva Olga I.
Published: August 2022

The article deals with the analysis of the origins and features of the formation of the “black legend” about Valentina Visconti, the wife of Duke Louis of Orleans and the sister-in-law of Charles VI. The author studies in detail all the sources of the turn of the 14th–15th centuries, which retold rumors that the Duchess was a witch who brought a spell on the French king, and disputes the point of view prevailing in historiography, according to which the creator of that “black legend” was one and the only person – the Hennegau chronicler Jean Froissart. According to the author of the article, rumors about Valentina Visconti arose much earlier than Froissart took up the compilation of his “Chronicles”, they were initially oral in nature and were primarily associated with the political propaganda of the Dukes of Burgundy, who were trying to gain full power in the French Kingdom
THE RETURN OF THE SHRINE AND ITS LEGITIMATION THROUGH LEGENDS. THE CASE OF ST. NICHOLAS THE WONDERWORKER, THE ICON OF KYLASOVO
Authors:   Perm State University, Korolyova Svetlana Yu.
Published: August 2022

The article focuses on the case of revered icon of St. Nicholas the Wonderworker from Kylasovo village of Perm Region. The author introduces the importance of legends in creating the existence of an icon as a sacral object and the ways the “breaks” of tradition are symbolically overcome. The paper outlines etiological plots related to the icon and the forms of its veneration as well as the history of the loss and re-acquisition of the shrine in the 20th century and reconstruction of the local tradition at the present stage. The earliest legends about the Kylasovo icon of St. Nicholas the Wonderworker (a phenomenon on the periphery of the cultural space, blinding of blasphemers) show that the plots have already become widely known and are updated in the south of the Perm region with the processes and events of the 17th–18th centuries. The realities of the Soviet era (the closure of a rural church, disappearance and discovery of a miraculous image hidden in a village house) contribute to a new round of the development of the oral tradition. The history of the salvation of the shrine was published on the official website of the church of Kylosovo village. It can be considered as the beginning of the inclusion of modern oral legends about this icon into the fields of official church culture. In the 2000s another problematic situation was the restoration (in fact, rewriting) of the revered icon. It should be noted about a link of a significant part of folk legends with “crisis points” in the life of the parish, caused by the “instability of being” of the local shrine (loss, transfer to another church, radical restoration). In such situations the legitimation of the current changes and confirmation of the miraculous nature of a religious relic as functions of religious become the important functions of religious narratives. Such functions are generally inherent in legends about shrines when modern material highlights their pragmatics more obvious
THE POST-SOVIET FATE OF ‘SOVIET ICONS’
Authors:   Russian State University for the Humanities, Antonov Dmitriy I. , Tyunina Sofya M. ,   Russian State University for the Humanities
Published: August 2022

The paper, based on the material s of scientific expeditions, describes the post-Soviet fate of handmade icons created by icon-makers of the Soviet era. The authors focus on the places in which ‘Soviet icons’ have existed since the collapse of the USSR, and on the roles they are assigned in the postSoviet socio-cultural space. Whereas during the Soviet era hand-made icons functioned primarily in the private homes, the last decades have seen some new sites of their existence, as churches, chapels, natural shrines, utility rooms of churches and monasteries, antique stores, flea markets, online-services for the sale of collectible and second-hand goods; finally, the abandoned houses. In some places Soviet icons serve a praying and protective function; form the iconostasis and spaces of rural natural sanctuaries. In other cases they lose their role as sacred objects and gradually disappear from the social space – either by falling into disrepair or through ritualized disposal. The authors describe also a practice of turning Soviet icons into a symbolic and material resource, as it happens in the case of the St. Nicholas Convent in Arzamas town
“COLOR REVOLUTIONS”. RUSSIAN HISTORIOGRAPHY OF THE ISSUE
Authors:   Lomonosov Moscow State University, Naumov Aleksandr O. , Demin Dmitrii V. ,   Lomonosov Moscow State University
Published: August 2022

The aim of the proposed research is to analyze the works of Russian specialists devoted to the issue of color revolutions. The authors state that the overthrow of S. Milosevic as a result of the first such “revolution” in Serbia in 2000 was not promptly reflected in Russian historiography, and that issue really became relevant only after the orange revolution in Ukraine. In general, for a series of color revolutions in the post-Soviet space in 2003–2005 Russian science responded with a series of articles in which researchers, mainly based on the political science concepts of transitology and democratization, focused on the analysis of the internal causes and prerequisites for regime change in Georgia, Ukraine and Kyrgyzstan. Since then, the understanding of color revolutions in Russian scientific discourse has evolved significantly, serious monographs have appeared, touching upon various aspects of that geopolitical phenomenon. In the course of the analysis of the most significant scientific articles and monographs, the authors of the article come to the conclusion that at the moment Russian scientific view has accumulated a significant amount of knowledge in the field of studying color revolutions, but the possibilities for further development of the direction in Russia are far from exhausted.
SCIENCE, EDUCATION AND TECHNOLOGIES AS A FACTOR SHAPING RUSSIAN-ARMENIAN TECHNOLOGICAL SPACE
Authors:   Russian-Armenian University, Avetisyan Parkev S.
Published: August 2022

The article analyzes the role of the science, education and technology for the formation of a single technological space of the Russian Federation and the Republic of Armenia in modern conditions. The author emphasizes that there is a definite lack of the new concept of scientific and technological cooperation between the Russian Federation and the Republic of Armenia, which could form the basis for close cooperation between the two countries at a new stage and provide the doctrinal structure pattern for the dynamic development projects and platforms for full-scale interstate cooperation created with the aim of forming a single scientific and technological space. The latter, as the author points out, should become a basic concept not only within the framework of bilateral relations but also on the scale of the Commonwealth of Independent States and the Eurasian Economic Union. The article defines the priority goals and directions for modernization of higher education in the two countries, the role of higher education to ensure national security. The author characterizes the trends in the publishing activity of researchers in Russia and Armenia over the past decade, based on the statistics of publications of scientists from the Russian Federation and the Republic of Armenia published in the international abstract and citation database Scopus, including joint publications of articles on leading branches of knowledge.

Authors:   Russian State University for the Humanities, Ershov Vitalii F.
Published: August 2022

The paper is a critical review of two books devoted to the peculiarities of the formation, social life and personalities of the North Caucasian diaspora in 20th century Europe: the monograph “North Caucasian emigrants in France” and the biographical dictionary “North Caucasians in emigration in the 20th century”. The reviewer notes that their author Irina Babich introduced into scientific circulation a diverse, full of valuable information complex of materials from French archives, creating on that basis a number of historical and ethnographic studies of the North Caucasian communities of Europe in the 1920s – 1930s. In the monograph under review, the author analyzes the social structure, everyday life and culture of emigrants from the North Caucasus who arrived to France in different periods of the 20th century. The study of sociopolitical movements and religious life of the North Caucasian communities, carried out on the basis of archival sources, is of considerable scientific interest. The reviewer proposes to consider biographical dictionary, prepared by a research team consisting of I.L. Babich, T.A. Gladkova and L.A. Mnukhin as an addition to the well-known series of reference books on the history of the Russian diaspora in France, edited by L.A. Mnukhin in the 1990s – 2000s. The reviewed publications together make an important contribution to the further development of the issues of the Russian far abroad in Europe, revealing, at the same time, the potential of new thematic perspectives in the development of that large topic related to the history of the peoples of Russia, trends of modern global development, the transformation of the concept of “diaspora” in international humanities.
