Authors: ÖZSOY Neslihan
Published: April 2020

In this study, optimum
machining conditions were determined by investigating the surface roughness of
the 7075-T6 aluminum alloy milling, depending on the spindle speed (rpm), feed
per tooth (Fz-mm/tooth) and the cooling type parameters. Taguchi experiment
design method was used to save time and cost. Experiments were based on the
Taguchi L16 orthogonal array and signal/noise (S/N) ratios were used in the
evaluation of the test results. Optimum surface roughness values were
determined with Taguchi optimization. In addition, variance analysis and
regression analysis were performed. Confirmation tests were conducted to verify
the work. As a result of the confirmation tests, it was found that the surface
roughness optimization in the milling of the 7075-T6 aluminium alloy was
successfully applied.

Today, many imaging tools have emerged in the
medical field using ionizing radiation. Computed tomography (CT) is regarded
the most creative and  common modality among the other imaging
devices. In CT imaging, radiation may scatter to the environment from the
patient and the interaction medium. In this study, two CT scanners with
 different slice numbers were used
to measure the scatter radiation dose to the
environment. Alderson rando phantom was utilized in the acquired CT exams as
human body simulation. Radiation dose levels at different distances were
determined by placing thermoluminescence dosimeters in the surrounding
environment (at different distances) during phantom’s head-neck and thorax CT
imaging. As a result, it
has been found that the radiation dose varies
between 13.90±1.96 µSv and 96.79±11.12 µSv in head and neck CT imaging. While,
in thorax CT scan,  the
radiation dose varies between 5.28±0.84 µSv and 20.63±1.76 µSv.

Published: April 2020

e-Migraine is a validated tool to estimate the severity of headache based on Migraine Comorbidity Index (MigCI) that includes comorbidities of migraine, age, baseline duration of headache (hours) and baseline frequency of headache (day/month). The aim of this study is to introduce the prediction tool for physicians to calculate the MigCI score easily. Our study sample consisted of 2012 patients enrolled in the Turkish Headache Database examined by neurologists between 2000 and 2015. Comorbidities were modeled according to posterior probabilities obtained from Latent Class Analysis. The score ranges of the baseline duration and frequency of migraine were determined according to previous studies and histogram charts. Age groups were designated by the classification of World Health Organization. An index formula was created by using all these variables and total score was calculated. The range of MigCI score was 1.02 and 17.22. The median value with the 25th and 75th percentiles were 4.44[2.96-6.00]. The MCI introduced in this study is the first to estimate the headache score considering the posterior probabilities as weights. e-Migraine is a practical tool that may help physicians to detect the headache score and suggest a treatment or care to the patients according to the score.

Published: April 2020

За последние сто лет многие существенные гравитационные явления были предсказаны и обнаружены Общей теорией относительности (GR), которая до сих пор остается лучшей теорией гравитации. Тем не менее, из-за великих наблюдательных открытий 20-го века некоторые (квантовые) теоретические и (астрофизические и космологические) феноменологические трудности современной гравитации были мотивацией для поиска болееобщей теории гравитации, чем ОТО. В результате были рассмотрены многие модификации ТО. Одним из многообещающих недавних исследований является нелокальная модифицированная гравитация. В этой статье мы представляем обзор некоторых нелокальных гравитационных моделей с их точными космологическими решениями, в которых нелокальность выражается аналитической функцией от оператора Даламбера — Бельтрами. Некоторые из полученных решений содержат эффекты, которые обычно присваиваютсятемной материи и темной энергии.

Published: April 2020

A liderança tem um papel estratégico, pois cabe a ela transmitir os princípios e valores que regem a organização, facilitando a adaptação e a integração dos funcionários, além de conceber e articular as metas que colocam as pessoas acima das preocupações individuais. O estilo de liderança praticado pelo líder pode incentivar a realização das atividades ou, pelo contrário, pode promover a competição negativa e desmotivar a equipe, sendo que, a falta de comprometimento prejudica a performance da empresa. Nesse sentido, esse estudo tem como objetivo identificar a importância do coaching e da liderança no desenvolvimento da equipe (funcionários e gestores) do segmento bancário em uma agência do setor público da Serra Gaúcha. A metodologia do estudo consiste em uma pesquisa descritiva, com abordagem quantitativa, por meio do uso de questionário estruturado, aplicado a cem por cento da equipe. Os resultados da pesquisa evidenciam que mais da metade dos funcionários entrevistados desconhece o coaching e a sua aplicação na prática. O estudo também evidencia que a maioria dos entrevistados não acredita que um processo de coaching influencie no atingimento das metas, por outro lado, a maioria mostra concordância sobre a necessidade de investimentos por parte da instituição bancária para a formação e o desenvolvimento de líderes.

Published: April 2020

This study is a first exploratory approach to identify differences and similarities between U.S. and Argentine farmers’ main management strategies. Considering the importance of agriculture in these countries and the key roles both of them play in agriculture world markets, our findings could help agribusiness industries and policymakers to make well-informed decisions based on a more comprehensive understanding of farmers’ behavior in both countries. Regarding sociodemographic aspects, U.S. farming is more family-operated, farmers are older, and farms are, on average, a smaller scale than in Argentina. The results show that U.S. farmers work more on their own farm compared to Argentine farmers. Regarding the factors considered more important in farm management, Argentine and U.S. farmers are more concerned about costs and productive aspects than about marketing issues or human resources aspects. This study also indicates that farmers in both countries prefer to do most of the farm tasks by themselves.

Published: April 2020

La educación superior requiere de una transformación significativa en sus procesos de enseñanza-aprendizaje debido al cambio significativo del entorno actual. Este nuevo contexto exige adaptaciones sustanciales en todos los aspectos asociados, particularmente por parte de los docentes. Por ello, se realizó un análisis de brechas para contrastar diferencias entre la importancia y el nivel de desarrollo de competencias académicas en docentes de la Universidad Autónoma de Chihuahua (UACH). Para esto, se aplicó una encuesta en línea a 372 profesores para evaluar seis factores que agrupan los dominios de las competencias docentes establecidas por la UACH como un perfil deseable. Se realizó un análisis cuantitativo descriptivo de medias y conglomerados. A partir de las agrupaciones arrojadas por el análisis estadístico, se demostró que las evaluaciones respecto a la importancia y desarrollo de las competencias docentes se polarizan al considerar la antigüedad de los docentes: los de mayor antigüedad evalúan consistentemente de manera más baja tanto la importancia como el desempeño logrado, en comparación con quienes tienen menos de 15 años como profesores. Asimismo, es evidente que se requiere replantear la participación docente en torno a varias de las competencias, como procesos de investigación, tutorías y valoración del desarrollo de competencias. Por lo tanto, se concluye que es necesario considerar la manera en que la antigüedad afecta la evaluación de las percepciones hechas según su importancia y nivel de desempeño.
The Yugoslavs in the Ethnocultural Space of Kuban in the Late 18th – Early 20th Centuries
Authors:   Kuban State Agrarian University, Zhabchik Svetlana Viktorovna
Published: April 2020

The study deals with some aspects of the Yugoslavs resettlement to the Kuban lands in the historical past. The Slavic community appears to us as a complex world of systematic mutual enrichment and merging of various ethnic groups. This was facilitated by the process of the Yugoslavs resettlement to the Kuban territory in connection with the tragic events in the places of their former residence. The peoples remained faithful to the Orthodox Church, namely Serbs, Bulgarians and Russians, became participants in the cultural exchange and mutual enrichment during a long historical period. In the modern world, this experience is extremely useful, as it strengthens and develops multifaceted ties between peoples of Slavic origin. The work is based on the works of pre-revolutionary researchers, as well as modern local lore scientists. Various archival materials and statistical sources were involved. The paper uses case studies to show the fruitful cooperation of the Slavic peoples who left a significant mark in the history of the Black Sea region. Analytical studies have shown that the Yugoslavs fitted perfectly into the ethnocultural space of the region. Some representatives of the Yugoslavs gained fame in the military field, the exploration, development and improvement of the new territory.
American Woman in Propaganda Games of the Cold War: Annabelle Bucar and her “Truth About American Diplomats”
Authors:   Northern (Arctic) Federal University, Feldt Aleksei Yegenyevich
Published: April 2020

In February 1949, the book with the title The Truth about American Diplomats by Annabelle Bucar was published in the Soviet Union. The author was a former officer of the U.S. Embassy in Moscow. The activity of her colleagues in this book was shown as very unpleasant. One year before this event, Bucar left the U.S. Embassy and married to a Soviet citizen, but she did not imagine that the fact of her transition on the side of the strategic enemy of the United States could be used as much as possible by the Soviet Intelligence services. The article analyzes how this situation has become a part of Soviet propaganda during the Cold War. Particular attention is paid to the problem of the authorship of the book, the main purpose of which was to create a negative image of American diplomacy among the Soviet readers during the period of growing confrontation between the USSR and the USA.
Dematerialization of Labor in the Art of Metamodernism
Authors:   Kuban Institute of Socioeconomics and Law branch of Academy of Labor and Social Relations, Bespalaya Olga Petrovna
Published: April 2020

The paper considers the problem of dematerialization of the artist’s labor in the situation of metamodernism. It is stated that the idea of labor, which has changed throughout history, undergoes significant metamorphoses in modern conditions. Artistic work is gaining ever-greater freedom from the material labor; the criterion of “done” in the modern artistic environment is losing its significance. The features of the situation, which is commonly called “metamodernism”, its differences from postmodernism, are examined. The author connects the process of abandoning labor and moving towards the dematerialization of artistic creativity with the emergence of a new metamodern discourse. As an illustration, examples are given from various trends in art (readymade, performance, network art). The relevance of the work is due to the fact that contemporary art, abandoning the irony of postmodernism, is looking for new ways of expression. The dematerialization of labor in this case is one of the options for the further development of artistic creativity.

Authors: Dieckmann Hayley G. , Costa Lais R. R. , Martínez-López Beatriz , Madigan John E.
Published: April 2020

OBJECTIVE

To describe an animal health database used to facilitate effective disaster response and retrospective analysis of data concerning animals other than cats and dogs affected by the 2018 California Camp Fire.

ANIMALS

Veterinary medical entries (n = 206) for evacuated or rescued animals (151) of various species, including avian, bovine, camelid, caprine, equine, ovine, and porcine species, temporarily housed at the Butte County fairgrounds in Gridley, Calif.

PROCEDURES

Case data were collected via a standardized form by volunteers with the University of California-Davis Veterinary Emergency Response Team during triage and treatment of animals brought to the shelter. Collected data were entered into a database. Multiple correspondence analysis was used to evaluate associations among patient species, types and severity of injuries, and behavior.

RESULTS

Burns, respiratory disease, gastrointestinal illnesses, and lacerations were the most prevalent illnesses and injuries among the overall shelter population for the first 12 days of the Camp Fire. Ovine patients were more likely to have had respiratory illness than were other species. The most prevalent medical conditions among equine patients were lacerations and gastrointestinal illnesses. Severe burns were most common among porcine, camelid, and avian patients. The temporal distribution of cases suggested the immediate evacuation of equine species and the delayed movement of bovine and avian species to the shelter.

CONCLUSIONS AND CLINICAL RELEVANCE

Collection of animal health information through the database allowed assessment of prevalent medical conditions among various farm animals following a wildfire. Adaptation of this database to other disasters could improve emergency response protocols by providing guidance for management of resources and allow retrospective assessment for response improvement.

Most of mankind’s living and workspace have been or going to be blended with smart technologies like the Internet of Things. The industrial domain has embraced automation technology, but agriculture automation is still in its infancy since the espousal has high investment costs and little commercialization of innovative technologies due to reliability issues. Machine vision is a potential technique for surveillance of crop health which can pinpoint the geolocation of crop stress in the field. Early statistics on crop health can hasten prevention strategies such as pesticide, fungicide applications to reduce the pollution impact on water, soil, and air ecosystems. This paper condenses the proposed machine vision relate research literature in agriculture to date to explore various pests, diseases, and weeds detection mechanisms.
Electric-Field Assisted Modulation of Surface Thermochemistry
Authors: Shetty Manish , Ardagh Matthew , Pang Yutong , Abdelrahman Omar , Dauenhauer Paul
Published: April 2020

Conventional catalyst design has enhanced reactivity and product selectivity through control of surface thermochemistry by tunable surface composition and the surrounding environment (e.g., pore structure). In this work, the prospect for electric field towards controlling product selectivity and reaction networks on the Pt(111) surface was evaluated with periodic density functional theory (DFT) calculations in concert with machine learning (ML) algorithms. Linear scaling relationships (LSRs) for adsorption energies of surface species in electric field were shown to: (i) be distinct as compared to zero-field LSRs across metals, and (ii) linearly correlate with adsorption energies of H* rather than the binding element. The slope of LSRs linearly correlated with the zero-field dipole moment. A random forest ML regression algorithm predicted field-dependent adsorption energies with a mean absolute error (0.12 eV) comparable to DFT. Overall, this study identifies the path forward for electric field-assisted catalysis, specifically towards catalyst poisoning, product selectivity, and control of reaction pathways.
An Investigation into the Identification of Potential Inhibitors of SARS-CoV-2 Main Protease Using Molecular Docking Study
Authors: Das Sourav , Sarmah Sharat , Lyndem Sona , Singha Roy Atanu
Published: April 2020

A new strain of a novel infectious disease affecting millions of people, caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has recently been declared as a pandemic by the World Health Organization (WHO). Currently, several clinical trials are underway to identify specific drugs for the treatment of this novel virus. The inhibition of the SARS-CoV-2 main protease is necessary for the blockage of the viral replication. Here, in this study, we have utilized a blind molecular docking approach to identify the possible inhibitors of the SARS-CoV-2 main protease, by screening a total of 33 molecules which includes natural products, anti-virals, anti-fungals, anti-nematodes and anti-protozoals. All the studied molecules could bind to the active site of the SARS-CoV-2 protease (PDB: 6Y84), out of which rutin (a natural compound) has the highest inhibitor efficiency among the 33 molecules studied, followed by ritonavir (control drug), emetine (anti-protozoal), hesperidin (a natural compound), lopinavir (control drug) and indinavir (anti-viral drug). All the molecules, studied out here could bind near the crucial catalytic residues, HIS41 and CYS145 of the main protease, and the molecules were surrounded by other active site residues like MET49, GLY143, HIS163, HIS164, GLU166, PRO168, and GLN189. As this study is based on molecular docking, hence being particular about the results obtained, requires extensive wet-lab experimentation and clinical trials under in vitro as well as in vivo conditions.

Novel compounds (4-amino-2-(phenylamino)thiazol-5-yl)(thiophene-2-yl)methanone and (4-amino-2-(4-chlorophenyl)aminothiazol-5-yl)(thiophene-2-yl)methanone are synthesized and characterized by UV, IR, 1H and 13C NMR, and high-resolution mass spectrometry. The structural optimization and the interpretation of theoretical vibrational spectra is made by the density functional theory calculation using Becke's three-parameter exchange functional in combination with the Lee—Yang—Parr correlation Gaussian 09 program package with the standard 6-311G basis software set. The equilibrium geometry, various bonding features, and harmonic vibrational wave numbers of the titled compound are investigated using the density functional theory calculation. Structural changes in the molecule due to the substitution of the electron withdrawing group are also analyzed. The Mülliken population analysis on atomic charges is performed. The thermodynamic stability in the ground state and reactivity of the compounds in the excited state are explained by the HOMO—LUMO energy gap. The molecular docking study is carried out using Hex 8.0. This study aids to understand the antibacterial activity of the compound.

Published: April 2020

Background

In December 2019, a pneumonia caused by a novel coronavirus (SARS-CoV-2) emerged in Wuhan, China and has rapidly spread around the world since then.

Aim

This study aims to understand the research gaps related to COVID-19 and propose recommendations for future research.

Methods

We undertook a scoping review of COVID-19, comprehensively searching databases and other sources to identify literature on COVID-19 between 1 December 2019 and 6 February 2020. We analysed the sources, publication date, type and topic of the retrieved articles/studies.

Results

We included 249 articles in this scoping review. More than half (59.0%) were conducted in China. Guidance/guidelines and consensuses statements (n = 56; 22.5%) were the most common. Most (n = 192; 77.1%) articles were published in peer-reviewed journals, 35 (14.1%) on preprint servers and 22 (8.8%) posted online. Ten genetic studies (4.0%) focused on the origin of SARS-CoV-2 while the topics of molecular studies varied. Nine of 22 epidemiological studies focused on estimating the basic reproduction number of COVID-19 infection (R0). Of all identified guidance/guidelines (n = 35), only ten fulfilled the strict principles of evidence-based practice. The number of articles published per day increased rapidly until the end of January.

Conclusion

The number of articles on COVID-19 steadily increased before 6 February 2020. However, they lack diversity and are almost non-existent in some study fields, such as clinical research. The findings suggest that evidence for the development of clinical practice guidelines and public health policies will be improved when more results from clinical research becomes available.

Motivated by the potential devastating effect of a COVID-19 outbreak in retirement homes and long-term facilities for dependent elderly, we present the impact of worst-case scenarios in French institutions using a specific age structure and case–age fatality ratios. The death toll could equal the yearly death toll caused by seasonal influenza in those older than 65 years or could largely exceed that, depending on the final attack rate and proportion of infected institutions.
ENCRYPTION AND DECRYPTION OF AUDIO SIGNAL BASED ON RSA ALGORITHN
Authors: Yousif Sura F.
Published: April 2020

One of the most important methods to protect and verify information that are exchanged over public communication channels in the existence of third party called antagonists is encryption. The stored or transmitted message is transformed in the encryption process to unreadable or gibberish form. The reverse process in which the intendent recipient can reveal the encrypted message content is called decryption. The encryption and decryption processes are achieved using secret keys that are exclusively exchanged between the sender and recipient. This method can be applied to any form of message such as audio, video, image or text data. The current work applies the well-known RSA algorithm for audio signal encryption and decryption. The performance of the presented algorithm has been tested via experimental implementation which show that the Cpestral Distance Measure (CD), Linear Predicative Code Measure (LPC) and Segmental Spectral Signal to Noise Ratio (SSSNR) reach to 6.8781, 4.9614 and -21.5563 dB respectively using Matlab simulations. The results on the presented technique validated that it is secure, reliable and efficient to be applied in secure audio communications as well as it performed high intelligibility of the recovered audio signal.

Published: April 2020

Objetivo: El propósito de este estudio fue determinar la relación entre el índice de masa corporal, el índice de masa grasa y la tensión arterial en un grupo de cadetes con sobrepeso. El índice de masa corporal no estima la adiposidad como sí sucede con el índice de masa grasa; a su vez, el exceso de adiposidad predispone el desarrollo de enfermedades cardiovasculares. Materiales y métodos: estudio observacional retrospectivo. Se aplicaron estadísticos descriptivos y correlación de Pearson. Resultados: 90 cadetes con edad promedio 22 ± 3años y con índice de masa corporal de 27,3 ± 2 kg/m2, hicieron parte del estudio. El índice de masa grasa no presentó diferencias significativas entre hombres y mujeres: 7,62 ± 2,37 kg/m2 y 7,8 ± 2,3kg/m2 respectivamente (p: 0,38). En hombres, la tensión arterial sistólica y diastólica fue normal y sin diferencias significativas (p > 0,05). En los hombres, la tensión arterial diastólica se relacionó con valor absoluto de la masa grasa (r= 0,420 p 0,00) y con el índice de masa grasa (r=0,386 p: 0,00). En las mujeres, el índice de masa grasa se relacionó con el índice de masa corporal (r= 0,516 p= 0,00) y la tensión arterial sistólica se relacionó con la circunferencia de la cintura (r= 0,357 p: 0,03). Conclusiones: en jóvenes militares el índice de masa corporal ≥ 25 kg/m2, no se relaciona con la tensión arterial y el índice de masa grasa, no sugiere sobrepeso por adiposidad.

Published: April 2020

The study investigated the effect of eggshell and groundnut husk as fillers on flexible polyether foam. The fillers with the particle sizes of 50µm each were mixed in the ratio of 50:50. Diverse percentages of the two combined fillers ranging from 10%, 20%, 30%, 40% and 50% were incorporated into the polyether recipes in the appropriate foam formulations and foam samples were produced. The unfilled foam (0%filler) served as the standard control sample. The physico-mechanical test carried out on the foam showed increase in the properties such as density, compression set test, indentation hardness test, tensile strength test and decrease for elongation at break test as compared to the unfilled foam. The scanning electron microscopy result showed the cell sizes became smaller and concentrated with an irregular shape as the filler load increased, thereby making it denser and thicker. Eggshell and groundnut husk fillers may be used in the making of flexible polyether foam since these materials are organic in natures. They can improve the mechanical properties and biodegradability of polyurethane product. The utilization of these fillers in polymer composites productin will help in sanitizing the environment by reducing landfills and producing eco-friendly waste and also it influences cost positively.

«Intelletto d’amore».
Authors: Mocan Mira
Published: April 2020

The essay takes into consideration the importance of the affective mysticism of the twelfth century for the beginnings and development of Dante’s poetry, starting from the novelty of ‘praise’ formulated in the Vita nova up to the most mature reworkings, in the canto XXIV of the Purgatorio and along the last cantos of the poem. The focus is on the works of William of Saint-Thierry, in particular on his Expositio in Cantica Canticorum, in which there is a first attestation of the formula intellectus amoris, a possible source for the famous Dante’s incipit Donne ch’avete intelletto d’amore and for the concept of love that follows from it. The essay then focuses on the high frequency of intertextual references to texts belonging to the tradition of affective mysticism, including the works of William himself, in early romance poetry, highlighting the continuity between this line of inspiration and Dante’s poetics.
Management of Primary Headache in the Emergency Department
Authors: Pescatore Richard
Published: April 2020

Headache is a common presentation to emergency departments (EDs), comprising nearly 4% of all ED admissions.‎1 While the overwhelming majority of patients present with a primary headache disorder, particularly migraine, the emergency physician’s role calls for the simultaneous exclusion of severe or life-threatening pathology while providing judicious and effective symptom relief.‎2 Notably, recent investigations suggest that this dual mandate performs well, excluding more than 99% of conditions resulting in serious adverse neurologic sequelae, though at the cost of high-frequency and low-yield advanced imaging utilization.‎3‎, 4 While a comprehensive understanding of the diagnostic process and underlying pathophysiology associated with headache disorders is critical for the emergency clinician, this review is meant to chiefly describe the treatment of primary headache and the variety, efficacy, and indications of those interventions. While individual headache type classification can be helpful in targeting approach or therapy, diagnosis can be difficult in the emergency setting, and primary headaches of most types are often approached similarly in the ED. Interestingly, the overwhelming majority of patients who present to an emergency department with acute primary headache have migraine, but the majority of patients receive a less specific diagnosis and a treatment that is correspondingly nonspecific.‎5 Importantly, however, the dynamic, diverse, and unique nature of different headache presentations to the ED make an algorithmic or step-wise approach to headache management ill-advised. The emergency practitioner must have a working knowledge of the array of treatment options available and apply therapies in a considered and informed manner. Following effective analgesia, however, the most important intervention emergency physicians can deliver for their headache patients is to connect them with outpatient physicians savvy about headache management, who will then provide these headache patients with appropriate acute therapeutics, initiate preventive therapy and provide anticipatory guidance about their disease process.‎6
Telemedicine Healthcare for Headache Medicine During COVID-19 and Beyond
Authors: Provenzano David
Published: April 2020

The current COVID-19 pandemic sheds light on the importance of telemedicine in the care of patients experiencing headaches. Generally, headache patients suffer from lack of access to healthcare and physicians specializing in headache medicine. Now more than ever, telemedicine is needed during the COVID-19 pandemic to limit unnecessary virus exposure while still providing high-level quality care.

Currently there is no published research regarding the risk of COVID-19 infections in headache patients. Nevertheless, headache patients must follow best practices like the rest of the population to limit their personal risk of infection and to mitigate virus community spread.
During this unprecedented public health crisis, our priority as headache specialists and health care professionals is to support social distancing while ensuring proper access to healthcare. Telemedicine will play a key role in expanding such access to physicians specializing in headache medicine. Furthermore, the expansion of telemedicine initiated during the COVID-19 pandemic will most likely continue once the pandemic ends secondary to documented high levels of acceptability, patient satisfaction, improvements in patient access, and cost of care reductions. The purpose of this manuscript is to define the current utilization of telemedicine for headache patients and to provide strategies for incorporation into headache care plans during the COVID-19 pandemic.

Practical Russian Language Skills as a Prerequisite for Academic Adaptation of the Central Asian Students
Authors: Korneva Galina Viktorovna , Gerasimova Elena Evgen'evna
Published: April 2020

The article is devoted to the problem of academic adaptation of the Central Asian students. The authors accentuate the fact that the Russian-language competence of the Central Asian students is limited to the sphere of everyday communication, it is not sufficient for studying at the Russian higher school; so, training students from the near abroad is associated with difficulties. It is emphasized that the sufficient Russian-language competence is a prerequisite for successful academic adaptation of this contingent of learners; therefore, purposeful systematic work is required to develop and improve the Central Asian students’ Russian-language skills.
