Authors: Zhao Jielin , Kho Dun
Published: May 2023

The research object is the role of China’s assistance in the implementation of Information and Communication Technologies projects in the context of international assistance of China to Africa, and the role of the Forum on China-Africa cooperation (FOCAC) in this process. The research subject is the set of measures used by China to provide such assistance including that within FOCAC. The author studies such aspects of the topic as the importance of Chinese transnational corporations operating in the field of communication technologies, the role of FOCAC as a platform helping realize effective cooperation between China and Africa in the field of telecommunication, and the reaction of Western countries to such actions of Beijing. To solve the research tasks the author uses the following methods: structural-logical, the system approach, historical and economical and statistical analysis. The author arrives at the following conclusions: 1) the Information and Communication Technologies field is one of the most promising market sectors for China in Africa, as its corporations have a range of advantages compared with their Western competitors; 2) in consideration of close connection between Chinese companies and the government, it is obvious that through this interaction, Beijing successfully extends the pool of its political partners; 3) FOCAC plays a special role as it is the only mechanism allowing China to realize its African vector of external policy bilaterally and multilaterally. The scientific novelty of the research consists in the fact that the author analyzes the topic which hasn’t been studied sufficiently enough in Russian and foreign historiography; the author analyzes new sources and attempts to define the role of FOCAC particularly in cooperation in the field of telecommunication.

Authors: Bershov Vladimir Nikolaevich
Published: May 2023

The subject of this research is the final stage of the struggle for independence of Syria (1945-1946). The article explores the “Anglo-French Agreement on Near East” of December 13, 1945, as well as the response of Syrian society to its conclusion. The author reviews the discussion in the United Nations Security Council  that took place on February 14-16, 1946 regarding the question of evacuation of foreign troops from the territory of Levant , as well as the results of decisions accepted in the UN Security Council that affected the attainment of independence of Syria. Moreover, the article analyzes the final stage of negotiations between Syrian, British and French governments, which led to evacuation of foreign troops from Syria on April 17, 1946. This event resumed the result of French mandate control in the country. The conclusion is made that the “Anglo-French Agreement on Near East” of December 13, 1945 became a breakthrough moment in the struggle of Syrian nation for independence. After it has been signed, the protest movement in Syrian cities reached its heights, forcing the government of Levant to propose it for consideration in the UN Security Council regarding the evacuation of foreign troops on February 14-16, 1946. Although no resolution has been adopted, the question received an international resonance. Under the international pressure, Britain and France had to withdraw their troops in April 1946. This marked another – Syrian – chapter of decolonization of Asian countries. The mandate system was left behind.
Changes in the policy of rendering British aid to the White Forces of Siberia and Southern Russia in July 1919 and their causes (based on the meeting protocol of the War Cabinet of July 25, 1919)
Authors: Mironiuk Sergei
Published: May 2023

The object of this research is the changes in the policy of rendering British aid to the White Forces of Siberia and Southern Russia in July 1919 and their causes. The subject of this research is the information on these matters, contained in the meeting protocol of the British War Cabinet of July 25, 1919 and related decision. Within the framework of the question “Situation in Russia”, were comprehensively discussed the reasonableness and possibilities of rendering British aid to A. V. Kolchak’s army in Siberia and A. I. Denikin’s army in Southern Russia. The author applies narrative method of research for description of documents that have not been previously introduced into the scientific discourse by the Russian scholars. The comparative method is used for correlation of data collected from various sources. The scientific novelty consists in the comprehensive examination of the claimed topic based on the meeting protocol of the War Cabinet of July 25, 1919, as well as other newly introduced documents from the United Kingdom National Archive. The author comes to the conclusion that the escalation of social tension in British society, major defeats of A. V. Kolchak, successful offensive operations of A. I. Denikin, along with the lack of financial resources for supporting the White Forces on all fronts, led to curtailing of British aid to Kolchak’s army and increased support of Denikin’s army, since his military achievements at the moment theoretically allowed counting upon invasion of Moscow.  
Manifestation of attributes of American culture in the works of George Balanchine
Authors: Fugina Ol'ga
Published: May 2023

The object of this research is the works of the Russian-American ballet master George Balanchine, viewed through the prism of dominant features of American culture, which in turn, were determined and formulated by the author (duality, permanent transformation, strive for innovation, American communicative behavior, “special” treatment of women, mass culture). In the course of this study, the author analyzes the cultural phenomena and processes common to the American society, as well as assesses the level of Balanchine’s integration into American culture as a creative individual and generator of ideas. The novelty of this research lies in the first ever culturological analysis of the work of George Balanchine; previously, his heritage was viewed from the perspective of art or ballet studies. It is concluded that despite the 50-year stay of George Balanchine in the United States, the nature of his creative thought remained Russian, while the means of realization leant on the American reality. Therefore, namely such cultural diffusion generated the new ballet aesthetics – neoclassical, which became traditional for the American ballet theatre. The conducted analysis allows to more profoundly understand Balanchine’s ballet heritage by the theoreticians and practitioners of ballet.

“The Secrets of Modern Petersburg” of V. P. Meshchersky and “The Remote House on Vasilyevsky Island” of V. P. Titov and A. S. Pushkin
Authors: Efimov Anton Sergeevich
Published: May 2023

This article examines the influence of the romantic-gothic novel The Remote House on Vasilyevsky Island” (1829) by V. P. Titov and A. S. Pushkin upon the anti-nihilistic novel “The Secrets of Modern Petersburg” (1877) by . P. Meshchersky. In the limelight is the evolution and sociopolitical adaptation of the romantic-gothic themes “invitation of evil spirits into the house” and “evil spirits obsessed with romantic passion towards a human”. The article demonstrates how the religious-mythological image of “evil spirits” (destructive beginning) undergoes “ideological transformation”, and in the conditions of development of realistic art in the middle XIX century “blends” at the artistic level of anti-nihilistic level with the image of a “nihilist”. The research is based on biographical, comparative and historical methods, as well as motif analysis. The sociopolitical context of the 1870’s is being considered. Problematic of the continuity of Pushkin’s storyline, characterology, and system of themes in the works of V. P. Meshchersky is an unexplored area. The study of influence of the narrative “The Remote House on Vasilyevsky Island” upon anti-nihilistic novel “The Secrets of Modern Petersburg” along with their comparative analysis have not been previously conducted. The article also comments on the historiosophical ides, which led Meshchersky to reconsideration of Pushkin’s storyline and its adaptation to the relevant sociopolitical realities of the 1870’s.

¿Enseñanza explícita o imitación? Cómo desarrollar algunos rasgos suprasegmentales en la producción oral de estudiantes de español hungaroparlantes
Authors: Baditzné Pálvölgyi Kata , Kovács Dorottya
Published: May 2023

Some former studies (Baditzné, 2019 and 2020; Kovács, in press) suggest the lack of chaining or fluency in the speech of Hungarian B2 CEFR level students of Spanish. On the basis of these previous results, we pose the question whether the pronunciation of Hungarian learners regarding these aspects can be further improved by making them aware of the phenomena of synalepha and resyllabification, and if so, which one is more effective: practicing its use through different simple activities, or the imitation of the oral production of native speakers. To answer the research question, the oral production (in the form of reading) of 10 Hungarian students was analysed regarding the synalepha and resyllabification, before and after they had participated in a brief individual training on the suprasegmental traits in question or who had been exposed to an authentic recording with native speech. According to our data, which can be considered preliminary, it is the explicit training that contributes to a greater extent to a more successful acquisition of the two phenomena.

défi du pluralisme et la contestation juridique d’une formation obligatoire pour toutes et tous en Éthique et culture religieuse
Authors: Bégin Luc
Published: May 2023

Das Curriculum Ethik und religiöse Kultur (Ethique et culture religieuse - ECR), das 2008 in Québec eingeführt wurde, bildet die letzte Etappe eines langen Prozesses der Dekonfessionalisierung der Schulen in Québec. Dieses nicht konfessionelle Curriculum, das sich als Antwort auf die Herausforderungen des Pluralismus der québec’schen Gesellschaft versteht, hat einen gewissen Widerstand, darunter zwei juristische Anfechtungen, ausgelöst. In beiden Fällen war das Obligatorium Teil der Auseinandersetzung. Der Beitrag analysiert diese beiden juristischen Fälle, indem er die darin entfalteten zentralen Argumente in Bezug auf die Ziele und die Struktur des ECR-Curriculums situiert. Die Wichtigkeit, das Obligatorium des Unterrichts beizubehalten – um adäquat auf die Herausforderungen des Pluralismus antworten zu können – und die Frage der Verletzung der Religionsfreiheit, welcher von den Richtern in den verschiedenen Instanzen besondere Aufmerksamkeit zukam, stehen im Zentrum der Analyse.

Published: May 2023

A bottleneck in high-throughput nanomaterials discovery is the pace at which new materials can be structurally characterized. Although current machine learning (ML) methods show promise for the automated processing of electron diffraction patterns (DPs), they fail in high-throughput experiments where DPs are collected from crystals with random orientations. Inspired by the human decision-making process, a framework for automated crystal system classification from DPs with arbitrary orientations was developed. A convolutional neural network was trained using evidential deep learning, and the predictive uncertainties were quantified and leveraged to fuse multiview predictions. Using vector map representations of DPs, the framework achieves an unprecedented testing accuracy of 0.94 in the examples considered, is robust to noise, and retains remarkable accuracy using experimental data. This work highlights the ability of ML be used to accelerate experimental high-throughput materials data analytics.
Synthesis of artificial cells via biocatalytic polymerisation-induced self-assembly

Published: May 2023

Artificial cells are biomimetic microstructures that mimic functions of natural cells and find application, e.g., as microreactors, as building blocks for molecular systems engineering, and to host synthetic biology pathways. Here, we report enzymatically synthesised polymer-based artificial cells with the ability to express proteins. They are created by biocatalytic atom transfer radical polymerization-induced self-assembly (bioPISA). The metalloprotein myoglobin synthesises amphiphilic block copolymers that self-assemble into structures ranging from micelles over worm-like micelles to polymersomes and giant unilamellar vesicles (GUVs). The GUVs encapsulate cargo during the polymerisation, including enzymes, nanoparticles, microparticles, plasmids and cell lysate. The resulting artificial cells act as microreactors for enzymatic reactions and for osteoblast-inspired biomineralization, and could express proteins when fed with amino acids, as shown by the expression of the fluorescent protein mClover and of actin. Actin polymerises in the vesicles and alters the artificial cell’s internal structure by creating internal compartments. Thus, bioPISA-derived GUVs mimic bacteria as they are composed of a microscopic reaction compartment that contains genetic information which is able to express proteins upon induction. bioPISA not only is a powerful tool in the pursuit of artificial cells but also for the easy and highly efficient encapsulation of biological molecules under mild conditions and in biologically relevant media. Therefore, it could have significant implications for the development of biomaterials and drug-delivery systems, as well as for cell encapsulation, and the in-situ formation of nano-objects.
Computation of Finite Temperature Mechanical Properties of Zeolitic Imidazolate Framework Glasses by Molecular Dynamics
Authors: Castel Nicolas , Coudert François-Xavier
Published: May 2023

Mechanical properties of amorphous phases of metal-organic frameworks (MOF), such as MOF glasses, are difficult to determine experimentally. Moreover, computational characterization is limited by the level of theory chosen for the description of interatomic interactions and is often computationally expensive. In this work, we have extensively investigated the computation of finite temperature mechanical properties of ZIF-4 in the crystal and glass phases. We critically assessed computational methodologies including ab initio molecular dynamics, reactive force fields, and classical force fields, based on a variety of glass models. We find that ZIF-4 glasses have a larger bulk modulus than the crystal and confirm previous studies that the density is larger for the glass phases. Moreover, we confirm in the case of zeolitic imidazolate framework (ZIF) glasses the relationship between density and bulk modulus, showing that obtaining models of correct density is key to the prediction of physical properties for these systems.
Heterogeneous Polymeric Matrix Induced Room-temperature Phosphorescence

Published: May 2023

Room-temperature phosphorescence (RTP) materials based on phosphor-doped polymers have been studied for more than sixty years. In these polymer-based RTP materials, the intrinsic structures and properties of polymeric matrixes are critical to their triplet emission. However, RTP materials with non-homogeneous matrixes are rarely studied, and far too little attention has been paid to the possible interferences of structures and components of polymeric matrixes on the final photophysical properties. In this work, we reported RTP materials with phase-separated matrixes consisting of two incompatible polymers, i.e., polystyrene (PS) and polyisoprene (PI). By doping difluoroboron β-diketonate derivatives into the blends or block copolymers of PS and PI, bright and long-lived green RTP emissions can be obtained under ambient conditions, while no afterglow can be observed in pure PS or PI homopolymers. The mechanism of triplet emission in heterogeneous matrixes was investigated. The findings of this work provide a new approach to the low-cost fabrication of RTP materials with comprehensive performances through high-throughput processing methods.
Colloidal Interactions in Ionic Liquids– the electrical double layer inferred from ion layering and aggregation
Authors: Espinosa-Marzal Rosa M. , Goodwin Zachary A. H. , Zhang Xuhui , Zheng Qianlu
Published: May 2023

Ionic liquids (ILs) are organic salts that remain liquid in absence of a solvent over a wide range of temperatures, often at room temperature. This chapter summarizes the progress in understanding colloidal interactions mediated by ILs and their electrical double layer (EDL) based on experimental observations and theory. It is well known that short-range oscillatory forces in ILs originate from the overscreening provided by ion layers that accumulate close to the charged surface. In contrast, the origin of the more surprising long-range decaying force is not well understood yet. There is experimental and theoretical evidence opposing the originally proposed dilute behavior of ILs, arising from either ion pair formation or solvent/voids/alkyl tails being the effective charge carrier. Here, we overview experiments and theory that supports an alternative explanation of this long-range force based on ion aggregation.
Model-based evaluation of piston reactor to produce hydrogen from methane via catalytic SMR and ATR routes
Authors: Abousrafa Aya , Katebah Mary , Linke Patrick , Al-Rawashdeh Mamoun , Jacobs Timothy
Published: May 2023

Piston reactor technology can enable process intensification for electrical and mechanical power conversion to chemical products. Previous work has investigated hydrogen production via partial oxidation of methane (POM) in piston reactors; however, other routes remain unexplored. This work aims to theoretically evaluate if catalytic steam methane reforming (SMR) and methane autothermal reforming (ATR) constitute promising routes for hydrogen production using piston reactor technology for typical parameters and conditions encountered in automotive internal combustion engines (ICE). Specifically, the aim is to use reactor modeling and consider process design aspects in the early stages of investigation to provide direction and justify the next research and development stages involving experimentation, while eliminating infeasible options from the further expensive analysis. The piston reactor is first modeled using a zero-dimensional thermodynamic single-zone piston model coupled with available steady-state kinetic models for these routes. This model-based analysis shows that the highly endothermic SMR reaction is not feasible at ICE conditions, leading to its elimination from further assessments and studies. Thermal coupling of an endothermic reaction with a side-exothermic reaction is a potential solution to drive thermodynamically limited endothermic reaction routes in the piston reactor. The reactor modeling revealed that operation become feasible by coupling SMR with POM in ATR-type scenarios and achieves process intensification compared to steady-state ATR reactors through a significantly higher hydrogen production per catalyst (287-fold increase) and similar methane conversion between 89% and 97% at significantly lowered intake feed temperature (reduced by 283 K). The implementation of ATR piston reactors into grey and blue hydrogen production process designs is explored to understand overall performance and economy of scale effects. The process design studies reveal that the piston reactor-based processes offer savings of approx. 20% in hydrogen production costs compared to conventional ATR processes considering identical plant sizes and natural gas prices. The hydrogen production study highlights the value of the implemented approach for quickly identifying promising directions for further detailed experimental and modeling studies during early-stage exploration.

Background Chronic kidney disease CKD is considered as one of the current public health problems associated with increased mortality rates. People with CKD have a greater likelihood for decreased function and quality of life QoL. It is important to encourage and incorporate exercises and physical activity to maintain healthy and active life.Aim The objectives of this study were to evaluate the adherence to exercise programme by patients diagnosed with CKD undergoing dialysis and to identify potential barriers for the same.Methods The observational study was carried out in the dialysis unit of a tertiary hospital. A total of 42 patients undergoing dialysis as outpatients in the hospital were enrolled for the study. The baseline outcome measures of joint range of motion and maximum repetition rate MRR testing of the selected muscles were done. Strengthening exercises by using resistance bands were carried out during haemodialysis and a home exercise program HEP to be followed on the remaining five days of the week was taught to the patients. At the end of three months adherence to the exercise regimen was evaluated using a questionnaire.Results At the end of 12 weeks 52 of the patients adhered to exercises during dialysis and 48 adhered to HEP. Conclusion Adherence to strengthening exercise programme in patients undergoing haemodialysis as outpatients in a tertiary hospital was found to be average. It is clinically essential to take this adherence rate into consideration while prescribing exercise program for patients undergoing dialysis.

Worksite wellness programs are often implemented to increase work productivity and improve the health in employees however there is very little evidence on how effective these programs are. This review of literature aims to investigate the impact Worksite Wellness Programs have on the physiological and psychological health-related outcomes in white-collar workers. Electronic databases including PubMed Web of Science and CINAHL were screened. Publications between 2010 and 2020 were included. A total of nine studies were reviewed. Six out of nine studies showed positive improvements in physical health characteristics like BMI fat mass waist circumference occupational sitting time and step counts. Four out of nine studies showed significant differences in psychological outcomes like quality of life emotional exhaustion ruminative depression and other stress-related symptoms. No significant changes were found in job satisfaction performance and cognitive function. The study yielded mixed results regarding the impact of wellness programs on health outcomes. There exists strong evidence demonstrating the impact of Worksite wellness programs on major physiological outcomes such as BMI step counts waist circumference sitting time waist-to-hip ratio and blood pressure. Significant reductions in major psychological outcomes such as anxiety and depression were reported.

The increasing need to obtain data on the meteorological situation to ensure the safety of aircraft flight actualizes the development of radar systems for remote collection and processing of information, including for solving the problems of classifying dangerous weather phenomena. This determined the primary development of the domestic weather radar complex of the near airfield zone (WR BZ). The article presents the features of the construction of the WR BZ, as well as the main tasks it solves. To classify meteorological phenomena from cloudiness to squall in the weather radar complex of the near airfield zone, it is proposed to take as a basis the criteria tested by weather radar stations of previous generations. These criteria are based on an analysis of the height distribution of reflectivity, taking into account the vertical temperature profile. In addition, a criterion for classifying thunderstorms in the cold period of time has been additionally introduced in the WR BZ. To calibrate the values of the criteria, a mathematical apparatus and special software were developed. To collect statistical data, WR BZ were installed in various climatic regions: the Central and North-Western Federal Districts and the Republic of Crimea. Further, an effective validation of the information received was carried out. At present, WR BZ has passed preliminary, acceptance, certification tests, trial operation, while demonstrating an effective classification of meteorological phenomena, thanks to the correct selection of decision criteria. The article considers the possibility of increasing the reliability and justification of the classification of dangerous meteorological phenomena through the additional use of information on the distribution of altitudes of the specific rate of dissipation of turbulent energy of the atmosphere, as well as an additional set of statistical data in various climatic zones of the European territory of Russia – the Upper Volga Region and the Krasnodar Region.

This study aimed to investigate the use of YouTube videos as a supplementary resource for EFL students. It uses a descriptive qualitative research method. The sample in this study was ten students in senior high school who had experienced learning EFL through YouTube as a supplementary resource for speaking fluency. The data collection instrument is a google form questionnaire with open-ended and close-ended questions. According to the findings, using YouTube in EFL classes positively supports speaking fluency for EFL learners, particularly in shaping and organizing ideas, enhancing motivation, developing and supporting peer collaboration, improving vocabulary, and reducing students' shyness. The current study's findings have clear implications for the teacher and students on how the students utilize YouTube as a supplementary resource in increasing their speaking fluency; the resource should focus more on developing student speaking fluency.
Some features of short-term blood pressure variability in patients with arterial hypertension in comparison with healthy volunteers
Authors: Kanishcheva Olena
Published: May 2023

Introduction. Blood pressure variability is a significant prognostic factor and an independent predictor of cardiovascular disease and mortality in patients with arterial hypertension. Objective. The objective of our study was to perform a comparative analysis of blood pressure variability indices in patients with hypertension and healthy volunteers. Materials and methods. 172 patients with arterial hypertension and 22 healthy volunteers took part in the study. All study participants underwent daily BP monitoring, based on the results of which short-term blood pressure variability was assessed. The results. In this open, non-randomized, single-point study, we first performed a comparative analysis of short-term BP variability in patients with hypertension and healthy volunteers. Currently, there is no generally accepted consensus regarding which of the proposed indices of BP variability is more informative. Therefore, in order to objectify the obtained data, we calculated several of the most widely used indices of short-term BP variability. In the main group all indices, SBP as well as DBP, were higher compared to the control group. However, the statistical significance of this difference was confirmed only for some, not for all indices. Conclusions. According to the results of the analysis of SD, SDw, CV, SV and ARV indices, a higher variability of blood pressure was established in patients with arterial hypertension compared to that in healthy volunteers. On the other hand, convincing data on the diagnostic informativeness of the CV index in the assessment of blood pressure variability were not obtained in this study.
