LEARNING BEHAVIOUR IN AN EXTRAORDINARY SITUATION
Authors: Knežević Žana , Tripković-Samardžić Vesna
Published: June 2021

Closures of higher educational institutions and cancellation of in-person classes caused by COVID-19 made ESP teachers in Montenegro find alternative ways to transform the serious emergency into an important opportunity to foster innovation in the area of teaching ESP online. Doing so, the teachers sought to enhance the experience already in place in many countries round the world. This paper deals with students’ responsiveness to employing new teaching methods aimed at increasing learner autonomy in virtual environment during COVID-19 pandemic, which inevitably encouraged the use of technology. The study focuses on two groups of students (19 second-year students of the Faculty of Visual Arts and 43 third-year students of the Faculty of Information Technology, University Mediterranean Podgorica, Montenegro) and their response to the alternative methods of teaching ESP, as well as the results they achieved in mid-term and final exams. The results are compared to those that the same group of students achieved in the previous semester, providing a comparative analysis of an impact of online teaching on students’ learning behaviour and accomplishments in the extraordinary situation.
INSTITUTIONAL STRATEGIES TO INCREASE EMI QUANTITY AND QUALITY IN RUSSIAN HIGHER EDUCATION INSTITUTIONS: COMPARATIVE ANALYSIS
Authors: Belyaeva Elena , Freese Michael
Published: June 2021

The article starts by examining the reasons behind the relatively recent growth of English as a medium of instruction (EMI) in Russian higher education institutions, from internationalization to more altruistic motives. While internationalization in Russia has recently been facilitated through a top-down approach at a national level, the quantity and quality of courses and programs taught in English are the responsibility of Russian universities and are primarily managed at an institutional level. Russian higher education institutions (HEIs) have been employing several strategies such as international recruiting, long-term university partnerships and faculty development. The authors take a closer look at each strategy, assessing its strengths and weaknesses, and illustrating it with some examples. Comparative analysis of the strategies under scrutiny allows to highlight more effective ones which are likely to positively impact the quantity and quality of EMI in Russian higher education in the years to come.
DOG – IMAGE PAREMIAS IN TRANSLATION (BASED ON NIKITA KHRUSHCHEV’S MEMOIRS)
Authors: Carter Elena V.
Published: June 2021

Animalistic metaphors are widely used in political discourse. The paper deals with the comparative analysis of Russian paremias with the constituent element “dog” employed in Nikita Khrushchev’s memoirs and their English translations. The etymology and cultural connotations of the phraseological units are explored as well. The corpus linguistics methodology is used to identify the expressions containing the word “dog.” By applying Conceptual Metaphor Theory and frame semantics, the mappings that serve to recreate the author’s view of “dog” cognition and communication for the reader are investigated. The research contributes to the study of phraseology and translation as it provides an insight into challenges caused by linguistic and cultural differences while transferring metaphorical expressions from one language and culture to another.
COMPARATIVE ANALYSIS OF POLITENESS STRATEGIES IN RUSSIAN AND ENGLISH DENTISTRY TEXTS
Authors: Grigoriev Ivan , Rubtsova Svetlana
Published: June 2021

The paper compares two corpora of Russian and English research articles in dentistry to identify differences between texts as regards evaluative language and other language tools to pursue politeness strategies. Positive politeness strategies are understood as a part of the positive evaluation process having the pragmatic function not to offence each other’s desire to be approved of. The study aims to define the politeness strategies that are most commonly used in Russian and English medical journals and to focus on the possible reasons for differences in Russian and Anglo-Saxon academic writing cultures that underlie the choice of politeness strategies. The analysis of the data shows that Russian research articles rarely employ politeness strategies if compared to their English counterpart preferring negative politeness strategies to positive ones. This study also provides some methodological advice for developing a syllabus in academic writing. Conclusions made on the basis of two compared corpora can also provide insights into both translation and contrastive studies.

The survey demonstrates that four-phase method of ESP listening contributes to eliminate lexical and sociocultural unawareness and develop communicative competence.
MAIN DIFFICULTIES IN TRANSLATING CONTRACTUAL DOCUMENTATION (ENGLISH/RUSSIAN)
Authors: Timofeeva Lilia , Morozova Maria , Potapova Tamara
Published: June 2021

The article is devoted to one of the most common translation problems in the sphere of law, namely finding the adequate equivalents in vocabulary, especially it concerns foreign terminology, in grammar and in text structure.While it is well-known that equivalence is one of the key concepts in translation, the research on practical applications of this principle in different professional spheres is still limited. With the rise of the interest to the machine translation, the special attention to the most common translation problems in the sphere of law can contribute to the overall understanding of the translation process. The methodological approach taken in this study is a mixed methodology based on comparative, structural, socio-linguistic and socio-cultural aspects of translation. The material presented in the article is based on the original contracts developed in English and Russian for the major oil and gas projects to be implemented in Russia 2006-2009. The examples of vocabulary, grammar and text structures equivalents can show the reasons for emergence of the main translation difficulties - polysemantic structure of some  terms, absence of concept  in either language, dependence of the meaning of the term on the context, idiomatic expressions, historically established traditions in legal text formation – emphasizing the idea that equivalence principle should be considered as a priority when translating contractual documentation.
ROLE OF ONLINE DISCUSSION FORUMS IN ENHANCING USERS’ COGNITIVE SKILLS
Authors: Ononiwu Charles
Published: June 2021

The study examines the role of online discussion forums (ODFs) in the learning process, using Garrison, Anderson and Archer's (2000) Community of Inquiry (CoI) model, particularly on the development of metacognitive skills, higher-order thinking skills and collaborative learning, all of which provide the impetus for workplace skills, such as analytical skills and teamwork. To achieve that, the study adopts the qualitative content analysis method to examine learners’ text submissions in the ODF. An ODF was set up on www.easyclass.com (an online learning management system), and students were invited to post their submissions in the forum bi-weekly for three months. A series of prompts from the course instructor were given to the learners in the ODF bi-weekly after the f2f classroom interaction. The prompts were designed to elicit students' responses, which would provide evidence of students’ learning, such as application of theory to practice, the abstraction of major ideas from a text, appropriate inferences and synthesis of ideas, etc. The analysis of the findings demonstrated evidence of metacognitive awareness, which was facilitated by the asynchronous nature of the discussion forum, as it gives learners sufficient time to engage in thorough research and careful thought before posting their submission. The findings also demonstrated that peer-to-peer knowledge dissemination is best stimulated using the ODF, as it gives learners opportunities to participate actively and to collaborate with their peers in the learning process.
CASE STUDY APPROACH TO TEACHING AND LEARNING ENGLISH FOR MEDICAL PURPOSES
Authors: Šelmić Nataša
Published: June 2021

The expression case study implies a wide range of issues presented for analysis, based on actual or simulated events that could logically occur. Besides, it involves profound research of phenomena or events. In medical education and practice, a case study represents an essential diagnostic procedure and investigation method used to create a profound understanding of an intricate problem in its real context. The implementation of the case study approach is of great importance in teaching English for medical purposes because the medical topics presented to students are familiar to them and medical terminology is applied to language learning. The case study is so structured as to serve the communicative function and provides the necessary content. It comprises the most relevant aspects in the field of medicine such as presenting signs and symptoms, performing different types of examinations, treatment, and health care management. The standard problem that needs to be solved is the patient’s problem, and establishing an adequate diagnosis is the goal. In this way, students develop critical thinking and reflective learning, improve organizational skills, as well as the ability to see the complexity of real-world events and understand the perspective of others.  This method has proven to be highly practical preparing students for reality, not theory workplace. In this way integration of language and the professional setting is enabled.
A PROPOSAL FOR PROFESSIONAL DEVELOPMENT OF BUSINESS ENGLISH TEACHERS IN SERBIA – OVERVIEW OF THE RESEARCH
Authors: Vidaković Mirna
Published: June 2021

This paper gives an overview of the empirical research conducted in the doctoral thesis entitled “A New Model of Professional Development of Business English Teachers in Serbia: Theoretical, Methodological and Practical Aspects”. Having noticed that professional needs of Business English teachers in Serbia were not sufficiently recognized, the research aimed to analyse the current situation regarding Business English teaching and professional development of teachers so as to gain data necessary for creating a proposal of a model of development that would fully respond to teachers’ pedagogical demands. The sample included 85 teachers and 349 students of Business English. Data collected through questionnaires and interview were analysed quantitatively and qualitatively. The results were largely consistent with contemporary research in the fields of LSP (Languages for Specific Purposes) and professional development of teachers. A few points which reflected a traditional approach to education concerned students’ perception of teachers’ roles and field competencies, and teachers’ expectations with regard to obtaining ready-made pedagogical solutions. The proposed model advocates a bottom-up and reflective approach to professional development, encourages both self-directed learning and collaboration, and offers content that suits teachers’ diverse experience and working contexts.
ESP STUDENTS’ ATTITUDES AND MOTIVATION BEFORE AND AFTER CROATIA JOINED THE ERASMUS PROGRAM
Authors: Kabalin Borenić Višnja
Published: June 2021

Results of our research study conducted before Croatia joined the Erasmus program in 2010 suggested that the experience of internationalization might affect ESP students’ attitudes, learning priorities and motivation. To establish whether generations that participated in academic mobility programs differ from their pre-Erasmus peers, we repeated our original study from 2009: Business and economics students’ attitudes to English, L2 motivation and invested effort were measured using the same questionnaire based on sociolinguistic and L2 motivation research rooted in social psychology. The same attitudes and motivation scales were used to compare the two groups. To ensure comparability, the data from the original and the present study were submitted to Coarsened Exact matching, which resulted in two subsets (N=98 each). T-test and correlational analyses revealed significant differences between the two groups, but the findings somewhat disappointed our previous expectations regarding the impact of university internationalization.
ОКУПЉАЊЕ ЛИБЕРАЛА ПОД ВОЂСТВОМ ЈОВАНА РИСТИЋА ОД 1868. ДО 1873. ГОДИНЕ
Authors: Pešić Miroslav
Published: June 2021

This paper shows the efforts of the Governorship, and especially Jovan Ristic’s efforts during the four-year mandate, to gather a large number of Liberals around him using various means. Most of the Liberals accepted the regime of the Governorship hoping that it would soften the political-bureaucratic regime by introducing certain reforms. The second governor, Jovan Ristic, together with the first one, Blaznavac, gathered political supporters around him using all levers of power, not even excluding the liberals of St. Andrea’s assembly, even though they had never seen him as their political ally. Despite the fact that he stood with an enemy of the liberals, Ilija Garasanin, Ristic managed to impose himself as their leader. This statesman started the reign with the movement of liberals, although he did not believe in the ideas of liberalism himself.
GENDER AND IDEOLOGY: WOMEN ON POSTAGE STAMPS IN SERBIA: 2006-2018
Authors: Bašaragin Margareta , Savić Svenka
Published: June 2021

In 2000 certain democratic changes happened in Serbia. They instilled hopes that everyday life will be more democratic in every segment, especially when gender equality is concerned (equality for the different, that is, women). The degree to which a society is democratic could be measured in different ways. One of them is the presence of visuals (drawings, etc.) or presence of any other form of material culture.The aim of this paper is to examine the degree of democratic changes in multinational, multi-confessional and multilingual Serbia during the last decade as it relates to the absence of linguistic codes, and using postage stamps to depict women (2006-2018). The corpus consists of all the postage stamps printed during the period, but only those depicting women were analysed. The analysis of the text on postage stamps opens up a theoretical question “What is text”?We here introduce the criterion of ‘implied knowledge’ as a measure for the understanding of the meaning of text on a stamp, more accurately, as a measure of the presence of an implicit discrimination towards notable women.The results reveal the following: 1. there are only several women who got the privilege to be presented on a postage stamp in this period; 2. all of them originate from the Serbian culture and none from other national communities. This clearly shows that the ideological decision is in question.
STRATEGIC COMMUNICATION AND SOCIAL NETWORK INFLUENCE: THE METHODS OF PSYCHOLOGICAL MANIPULATIONS IN CYBERSPACE AND THE SUGGESTION FOR ITS PREVENTION
Authors: Mitrović Miroslav , Vasiljević Dragan
Published: June 2021

Strategic communication is one of the expressions of state power and the instrument for achieving political and the security of national interests. In the context of contemporary conflicts, it is an appearance of hybrid action in the fields of information, the media, the Internet and the wide spectrum of public diplomacy performances. The main goal of strategic communication (SC) is to influence public opinion. In addition, SC strives to move the focus of the public towards cultural values as well as the adjustment of the political system. The main task of strategic communication (SC) is to influence public opinion and its focus on cultural values, the possible adaptation of the political system by "reprogramming" political culture in accordance with the goals set by psychological influence. One of the main channels for influence are social networks. In the paper, we used a multi-criterion analysis to identify the method of prevention pertaining to psychological manipulations in the cyberspace. This paper suggests preventive measures against negative impacts of social networks. In the paper, we used the Analytic Hierarchical Processes for the analysis of hierarchy in the application of preventive measures. Based on the obtained results, we developed and presented the application of preventive measures, to prevent the harmful effects of psychological manipulations in the cyberspace.
CYBERSECURITY – VIRTUAL SPACE AS AN AREA FOR COVERT TERRORIST ACTIVITIES OF RADICAL ISLAMISTS
Authors: Trifunović Darko
Published: June 2021

Over time, terrorism has evolved into different forms. One of the most dangerous is certainly cyber terrorism. There are many different motivations for terrorists to deploy cyber terrorism as a tool in their fight. Internet and computer networks are powerful resources on which contemporary society relies heavily. Terrorist groups have developed new tools and methods of the fight and they have become more effective, efficient, and unpredictable. Virtual, or cyberspace, is perfect and very safe ground for terrorist groups’ various activities, such are secret encrypted communication, file sharing, indoctrination and recruitment of vulnerable individuals, fundraising and promotions of their future actions and accomplishments spreading fear among common people. Are we adequately aware of these facts and prepared for countermeasures? The fact is that terrorists use mostly open-source tools (software) for their purposes, widely available and free of charge, as well as video games, popular social networks (mostly Twitter), and software developed by their programmers. The purpose of this paper is to point out some of the methods radical Islamic terrorist groups have been using and underline the importance of responding to this new security challenge.

Authors:   Policía Nacional de Colombia, Medellín, Colombia, Ochoa Díaz Alex Gabriel , Páramo Pablo ,   Universidad Pedagógica Nacional, Bogotá, Colombia
Published: June 2021

El presente estudio tiene como propósito caracterizar el fenómeno de la extorsión como práctica delictiva en el departamento del Caquetá (Colombia), a partir del perfil general derivado de la identificación de algunas variables que diferencian los modus operandi de los principales autores de este flagelo. Se realizó el análisis de 52 casos de extorsión en la región a partir de la sistematización de las denuncias interpuestas por las víctimas, lo cual permitió identificar las variables que caracterizan el delito. La información fue sistematizada y analizada con el programa Multidimensional Scalogram Analysis (MSA), con el cual se evidencia que el delito de extorsión es estructurado al mostrar similitud en el accionar de los distintos grupos criminales que actúan en la zona, lo que contribuye a esclarecer en cierto grado el responsable y su modalidad extorsiva. Se discute la importancia del análisis centrado en el MSA para la perfilación de la extorsión y sus implicaciones en el esclarecimiento de otros delitos dentro de la investigación criminal.

Necropolítica no Estado do Rio de Janeiro.
Authors: Ferreira Ítalo do Couto
Published: June 2021

A presente pesquisa visou analisar a eficiência e a eficácia da política de morte, ou necropolítica, adotada como política de segurança pública pelo governador do Estado do Rio de Janeiro, Wilson Witzel. Para tal, foi testada estatisticamente a relação entre o aumento dos homicídios por intervenção policial e a diminuição dos homicídios dolosos, compilando-se dados dessas variáveis do primeiro semestre de 1998 até o primeiro semestre de 2019, constatando-se que não existe evidência estatística que comprove essa relação entre as variáveis. Qualitativamente, analisou-se o discurso de morte do governador à luz da Necropolítica, de MBEMBE (2016), e da filosofia dos direitos humanos aplicada à atuação policial, demonstrando que essa política e discurso de morte, ilegalmente, submete os moradores das favelas fluminenses a um estado de exceção, que mata, desumaniza e fere a dignidade da pessoa humana. Além disso, à luz do direito internacional e nacional, foi demonstrado que a necropolítica adotada pelo governo Witzel infringe os tratados de direitos humanos e as leis nacionais quanto ao uso da força por policiais, sobretudo, utilizando armas de fogo.

Published: June 2021

O objetivo deste artigo é explicitar as contradições da defesa dos serviços oferecidos pelas academias de ginástica como essenciais à saúde em momentos de intensificação de casos da Covid-19. Analisou-se o modo como a concepção hegemônica que relaciona exercício físico e saúde é utilizada para justificar a reabertura destes estabelecimentos em momento de ascensão de casos e óbitos. Buscamos evidenciar como esse discurso assume um caráter ideológico. Apesar de ser uma necessidade, o exercício físico, produzido como mercadoria, apresenta seu valor de uso subsumido ao valor de troca, ou seja, é produzido prioritariamente para responder à necessidade de acumulação de capital. Reiteramos nossa concordância com a importância do exercício físico à saúde, mas problematizamos que deve ser considerado como uma necessidade historicamente produzida, portanto, articulada à particularidade de determinado momento histórico.

Published: June 2021

El presente trabajo consistió en la simulación del control automático en el domo de una caldera acuotubular, para conocer en detalle el comportamiento del nivel y presión y su influencia en la operación de la caldera. Para obtener la dinámica de cada una de las variables en el domo, se utilizó el software de calderas. Se realizaron diferentes perturbaciones en modo manual para recolectar datos y posteriormente ajustarlos a un modelo dinámico. Con las funciones ajustadas, se propuso una estrategia de control multivariable MIMO 2x2, que se validó con el criterio de ganancia relativa procediendo a la metodología de desacople.
Los parámetros de cada controlador fueron sintonizados por el método BLT para sistemas multivariables y validados con el criterio de estabilidad de Nyquist. Se simuló el sistema 2x2 en el software Control Station con los controladores en automático y se realizaron perturbaciones tipo escalón para observar la influencia que tiene cada parámetro del controlador PID en el tiempo de respuesta, oscilación y offset de las variables controladas y su reflejo en las demás variables. Con el criterio de overshoot y rise time se volvió a sintonizar cada parámetro.
Para garantizar que la dinámica en el domo se mantenga controlada, se realizó perturbaciones para servo control y control regulador obteniendo resultados satisfactorios para cada sistema. Se demostró que los controladores PID responderán de manera rápida y eficiente.

Authors: Buelvas-Caro Saúl David , Aguas-Mendoza Yelitza del Rosario , Olivero-Verbel Rafael Enrique
Published: June 2021

Biocoagulants have emerged as an environmentally friendly and efficient alternative to surface water clarification, allowing the use of agro-industrial waste as a bioavailable source for the treatment of high turbidity water. The objective of this research was to compare the efficiency in the surface water coagulation process of the Magdalena river using aluminum sulfate and tamarind seeds (Tamarindus indica) dissolved in aqueous solution and saline solution. The clarification process was carried out by testing jar, for this was performed an extraction of the hot and cold tamarind coagulant which were evaluated in conjunction with an inorganic coagulant in different mother dilutions (distilled water and saline) at concentrations of 35 and 40 mg/L and at a stirring speed of 100 and 200 rpm. The parameters of pH, electrical conductivity (S/cm), turbidity (NTU) and color (UPC) were measured during the clarification process. The results show a 97.2% reduction in inorganic treatment (SAL) compared to initial turbidity and a decrease in natural cold extracted (STF) and hot (STC) treatments of 58.2% and 39.1% respectively, when diluted in aqueous solution. While diluting in saline solution there was a greater removal of turbidity when applying aluminum sulfate, followed by STF and STC treatment, with removal values of 99%, 75% and 53% respectively. The highest coagulating activity occurred when applying a dose of 40mg/L and when diluting treatments in NaCl with maximum reported values for SAL, STF and STC treatment of 93%, 85% and 59%. Tamarind seeds proved to be an efficient coagulant for water clarification

Populus has a wide ecogeographical range spanning the Northern
Hemisphere, and exhibits abundant distinct species and hybrids globally.
Populus tomentosa Carr. is widely distributed and cultivated in
the eastern region of Asia, where it plays multiple important roles in
forestry, agriculture, conservation, and urban horticulture. Reference
genomes are available for several Populus species, however, our
goals were to produce a very high quality de novo, chromosome-level
genome assembly in P. tomentosa genome that could serve as a
reference for evolutionary and ecological studies of hybrid speciation.
Here, combining long-read sequencing and Hi-C scaffolding, we present a
high-quality, haplotype-resolved genome assembly. The genome size was
740.2 Mb, with a contig N50 size of 5.47 Mb and a scaffold N50 size of
46.68 Mb, consisting of 38 chromosomes, as expected with the known
diploid chromosome number (2n=2x=38). A total of 59,124 protein-coding
genes were identified. Phylogenomic analyses revealed that P.
tomentosa is comprised of two distinct subgenomes, which we
deomonstrate is likely to have resulted from hybridization between
Populus adenopoda as the female parent and Populus alba
var. pyramidalis as the male parent, approximately 3.93 Mya.
Although highly colinear, significant structural variation was also
found between the two subgenomes. Our study provides a valuable resource
for ecological genetics and forest biotechnology.
Warming drives sustained plant phosphorus demand in a humid tropical forest

Phosphorus (P) is often one of the most limiting nutrients in highly
weathered soils of humid tropical forests, which may regulate the
responses of carbon (C) feedback to climate warming. Based on a 7-year
continuous field warming experiment conducted by translocating microcosm
forest ecosystems from a high-elevation site to low-elevation sites, we
detected changes in the ecosystem P cycle in response to warming. We
report that warming drives sustained plant P demand by increasing P
uptake and thus decreasing foliar N:P. This increased plant P content is
supplied by multiple processes including enhanced plant P resorption,
soil P mineralization and dissolution without changing litter P
mineralization and leachate P. These findings suggest that warming may

Objective: To compare plasma free amino acid (FAA) and carnitine levels
in pregnant women with and without hydatidiform mole (HM). Methods: This
prospective study was conducted in patients admitted to Harran
University Medical Faculty Hospital Obstetrics Clinic between January
and November 2018. Twenty-three pregnant women with HM, and 24 healthy
pregnant women as controls were enrolled in the study. The venous blood
samples were collected, and, FAA and carnitine concentrations were
measured in plasma using liquid chromatography/tandem mass spectrometry
(LC-MS/MS). Results: The levels of alanine, arginine, and valine from
the 14 amino acids examined were significantly lower in the HM group
than in the healthy group (475.46 ± 103.55 µmol/L vs 556.99 ± 105.16
µmol/L, p = 0.019; 428.87 ± 138.91 µmol/L vs 547.11 ± 140.20 µmol/L, p =
0.009; and 290.96 ± 97.10 µmol/L vs 358.61 ± 75.40 µmol/L, p = 0.03;
respectively). In addition, several carnitines, C8DC, C16:1, and C18, of
the 27 carnitines examined were significantly higher in the HM group
than in the control group (0.07 ± 0.06 µmol/L vs 0.03 ± 0.01 µmol/L, p =
0.021; 0.18 ± 0.09 µmol/L vs 0.10 ± 0.06 µmol/L, p = 0.03; and 0.07 ±
0.02 µmol/L vs 0.03 ± 0.01 µmol/L, p = 0.021; respectively). Conclusion:
This study demonstrated that a decrease in some plasma FAAs and an
increase in some plasma carnitine levels might be effective in the
pathogenesis of HM.
Protective effects of astragaloside IV against hypertension-induced vascular remodeling involves the DNMT1 and TET2 signaling pathway

Proliferation, migration, and the phenotypic switch of vascular smooth muscle cells (VSMCs) play an important role in vascular remodeling induced by hypertension. Astragaloside IV (AS-IV), the active ingredient of Astragalus membranaceus, has been shown to exert a beneficial role in cardiovascular disease. The present study aimed to investigate the mechanism responsible for the protective effects of AS-IV on hypertension-induced vascular remodeling. AS-IV significantly reduced blood pressure and aortic media thickness in two-kidney, one-clip (2K1C) hypertensive rats. AS-IV administration downregulated the expression levels of DNA methyltransferase1 (DNMT1), matrix metalloproteinase (MMP2) and proliferating cell nuclear antigen (PCNA) and upregulated the expression of smooth muscle 22? protein (SM22?), ?-smooth muscle actin (ACTA2) and ten-eleven translocation 2 (TET2) in the aorta of hypertensive rats. AS-IV inhibited the proliferation and migration in VSMCs treated with angiotensin II (Ang II). AS-IV increased the expression of SM22?, ACTA2 and TET2, and decreased the expression of collagen Ia (COL-1a), collagen IIIa (COL-3a), DNMT1, MMP2 and PCNA in vitro. Reduction in 5-methylcytosine (5-mC) was observed in VSMCs treated with AS-IV. Knockdown of DNMT1 induced the expression of TET2, while the level of DNMT1 did not change after knockdown of TET2. These results suggest that AS-IV reversed hypertension-induced vascular remodeling by inhibiting DNMT1 and upregulating TET2.

The article deals with the question of building hard, soft and self-skills among students – centennials. The article presents the results of four – year (from 2017 to 2021) work with students of the School of computer sciences and robotics as part of educational course “Entrepreneurial behavior”. During this period, more than 400 students of the 2nd year, aged 19–20 years, took part in the study, of which 93 % were men. The geography of respondents is presented from Kaliningrad to Blagoveshchensk, including Tomsk, Novosibirsk, Kemerovo regions, Altai and Krasnoyarsk territories, the Republic of Altai and Buryatia, and foreign students from Kazakhstan, China, and Vietnam took part in this study. The author suggests the models for the building hard, soft and self-skills of students. The author considers the Tshaped model which is aimed at the simultaneous development of hard and soft skills. The Vshaped model offers the building hard skills at the intersection of two new professions from the future. The W model, so named the model of winner, is a model that allows to develop, first of all, self-skills. These model helps to train a creative and proactive specialist who is able not only to use what is available, but also to create something new.
