THE INFLUENCE OF THE MAGNETIC FIELD ON SUPERCONDUCTING AND NORMAL CHARACTERISTICS OF YBA2CU3OX POLYCRYSTALS SUBJECT TO TIME DEGRADATION
Abstract
The effect of a constant magnetic field on the superconducting and normal characteristics of YBa2Cu3OX (Y123) polycrystals, preserved at room temperature for a long time, was examined using the resistivity curves r (T) at a constant transport current of 10mA in the temperature range (77-290) K. The width of the superconducting transition (DΤC) and its critical temperature (ΤC) were considered as superconducting characteristics. Moreover, ΤC was determined by the temperatures corresponding to the onset, middle, and end of the transition (ΤCon, Tc0.5, and Tc0).
Given the fact that the magnetic-field dependence of resistivity (magnetoresistance) is considered as a normal characteristic in the fluctuation range (Tc0 <T <ΤCon), it is shown that all the characteristics under consideration expose monotonic behavior depending on the magnetic field. Moreover, parallel to the increase in the magnetic field, the critical temperature not only decreases but also shows an anomalous growth, the maximum value of which for Tcon, Tc0.5 and Tc0 was accordingly 5.3K, 4.2K and 2.9K, which means that depending on the magnetic field, Tcon is most unstable. Depending on the magnetic field, asynchronous change in Tcon indicates that both characteristics are conditioned by the same mechanism. It has been revealed that the behavior of the magnetoresistance in the range of fluctuation is strictly temperature-dependent. It has also been found out that negative magnetoresistance is observed over the entire range of the applied magnetic field at 92 K, whereas at higher temperatures, both negative and positive types of magnetoresistance are observed. Also, it was proved that changes in superconducting and normal characteristics, depending on the magnetic resistance, occur in reverse phases, i.e. in the case of a change in the magnetic field, the growth of one is accompanied by a simultaneous contraction of the other and vice versa.
The results obtained were observed within the framework of the model of structural inhomogeneities at a microscopic level in samples subjected to temporary degradation.
Keywords and phrases. High-temperature superconductor (HTS), superconducting transition (ST), ST width, onset, the middle and final temperature of ST (DΤC, Tc0.5, Tc0.5 and Tc0), magnetoresistance․

ENSURING GAS SAFETY VIA MICROPROCESSOR BASED
GAS DETECTING DEVICE
Abstract
This article is devoted to the design and production of micro-processor based gas analyzing and detecting device of the new generation. Two methods were chosen for the gas detection process, one of which is the catalytic combustion method based on heat generated by combustible gas burning on an oxidation catalyst, and the second one is electrochemical principle-based measurements which use an electrochemical sensor to detect gas concentration by measuring current based on the electrochemical principle, which utilizes the electrochemical oxidation process of target gas on the working electrode inside the electrolytic cell, the current produced in the electrochemical reaction of the target gas is in direct proportion with its concentration while following Faraday law, then concentration of the gas could be get by measuring value of current.
The combination of these sensors provides low consumption, high precision, high sensitivity, wide linear range, good anti-interference ability, excellent repeatability and stability of the detector results.
Adding a microprocessor to the sensors which work by the above-mentioned methods, we assembled gas detecting and analyzing device “ELAR”, which is a microprocessor-based and software-controlled device (hereinafter referred to as the "signalling device"), used in rooms to detect leaks of natural gas (CH4) and increased concentration of incompletely burnt carbon monoxide (Co). When triggered, the alarm emits a loud sound and light signal and also sends a command to close the solenoid valve, cut off the supply of combustible gas, to prevent an explosion from gas leakage, fire or human casualties.
As a result, it is expected to have gas analyzing and detecting device of a new generation which won’t react to other gases apart from CH4 and Co, will have a self-calibration function with special software, 0 adjustments, auto-calibration when in use, alarming when detectors are out of order, as well as will register data by time and incidents in non-volatile memory. They will have the ability to read incidents using a computer program.
Keywords and phrases. Catalytic combustion method, compensation element, lower-explosion-limit (LEL), electrochemical oxidation process, electrolytic cell, electrochemical reaction.

NUTRITION, PROBIOTICS AND Periodic disease: DNA methylation of commensal Escherichia coli
Abstract
Keeping specific diets is one of the main points in managing many diseases. It is also known that the intake of certain food might provide predictable shifts in gut bacterial communities in diseases. On the other hand, probiotics are suggested to restore the unfavourable changes in gut microbiota. Moreover, food enriched with specific probiotics might be the basis of certain diets, but the selection of probiotics and its targeted delivery through food requires serious scientific-technological approaches to stimulate/keep the growth of probiotic through synbiotic nutrition.
Periodic disease /PD, FMF, familial Mediterranean fever/, the autosomal recessive and systemic autoinflammatory disorder, is characterized by recurrent bouts of fever, serositis, synovitis, and/or cutaneous inflammation. A low-salt/low-fat diet may be used in the management of PD patients. The exact role of intestinal bacteria is not yet fully understood, but the potential for host-microbiota dialogue is widely discussed in the pathogenesis of PD.
This study aimed to clarify whether the investigations on DNA methylation of gut commensal E. coli from FMF patients had actuality for evaluating host-microbiota dialogue.
The following keywords- E. coli, gut, FMF and DNA methylation were used to collect data from PubMed (1990-2021).
The analysis of the literature data substantiated the usefulness of the investigations on DNA methylation of gut commensal E. coli in FMF disease for the evaluation of host-microbiota dialogue.
Keywords and phrases. FMF, probiotic, E. coli, methylation, DNA, gut microbiota.

PROTECTIVE EFFECT OF BACTERIAL MELANIN ON SUBSTANTIA
NIGRA IN PARKINSON'S DISEASE
Abstract
Parkinson's (PD) disease is a common movement disorder in a wide range of neurodegenerative diseases, often associated with gradual personality degradation. The major reason for PD is the progressive disturbance of dopaminergic neurons of the substantia nigra pars compacta. Therefore, therapy aimed at slowing the death of dopaminergic neurons can be effective. In the treatment of neurodegenerative diseases, various kinds of neuroprotectors are successfully used, after which the recovery of lost functions of the central nervous system is accelerated. In the present study, bacterial melanin was used for this purpose.
A comparative study of the morphofunctional state of the cell structures of the compact substantia nigra in rats was conducted on the rotenone model of PD and in combination with the administration of bacterial melanin.
For the morphological and histochemical study, we used the method of detecting the activity of Ca2 + - dependent acid phosphatase.
The data analysis showed that during rotenone intoxication of the brain, neuronal death and substantia nigra depigmentation are observed, sharp morphological changes in intracellular structures occur, which indicates gross metabolic and morphological disorders. With the introduction of bacterial melanin, there is a tendency to preserve the typical morphological picture of the neurons of the substantia nigra pars compacta compared to the model of PD. Obtained data give reason to suggest bacterial melanin acts as a neuroprotective agent.
Keywords and phrases. Substantia nigra pars compacta, bacterial melanin, PD model.

EXPRESS NALYSIS OF UNKNOWN ORGANIC SUBSTANCES
Conducting chemical experiments and analyzing them take up most of the time from all the work of scientists. Any chemist can mix and dissolve reagents, but for some research and experiments, you need to repeat the same manipulations hundreds of times while maintaining the accuracy of the proportions of the reagents. Besides, a considerable amount of effort is spent combining reagents with each other and fixing the results obtained. All these processes are similar in that they require repeating the same actions with a slight difference in the variables.
Of course, modern instrumental methods of chemical analysis come to the rescue. They are highly accurate, based on the latest principles of contemporary science, and often require modern equipment and highly specialized service personnel. The work of the laboratory staff is based on the analysis of the received samples of raw materials and products. At the same time, working in a chemical laboratory can be dangerous, and specific standards and requirements for equipment and reagent storage have been developed to protect the personnel.
Therefore, to achieve the best results, it is necessary to make substantial financial and labour intensive investments in chemical laboratories. This is fully justified in a number of forensic and innovative research laboratories, where each study is unique and often has several legal implications.
However, a large number of chemical laboratories carry out routine work daily. A fully equipped chemical laboratory allows you to study the properties of individual substances and materials, to observe the course of the interaction of reagents. The main goal of the employees of chemical laboratories is to create and implement express methods for the analysis of samples, which allow for quality control in the "field" conditions. Work is constantly underway to speed up the preparation of samples for research, and screening methods of analysis are being introduced. These laboratories need daily rapid tests that can be performed quickly and inexpensively. Using relatively inexpensive chemical reagents, the simplest physicochemical, color, and other tests presented in the article, the laboratory will quickly and efficiently complete its daily task while avoiding expensive equipment.
We hope that this work will be helpful, especially for environmental and chemical laboratories with limited resources and factory and various industrial laboratories, because as a result, both material resources and, most importantly, time are saved.
Keywords and phrases. Organic compounds, solvent, solubility, aliphatic and aromatic hydrocarbons, alcohols, aldehydes, ketones.

SOCIO-PSYCHOLOGICAL CHARACTERISTICS OF GROUP RELIABILITY OF PHYSICIANS IN EMERGENCIES COVID-19 PANDEMIC
Abstract
This article presents the scientific hypothesis that the socio-psychological profile of group reliability of physicians in emergencies is formed mainly by active professional-personal qualities of group members, such as sincerity, personal responsibility and awareness and work efficiency. To prove the presented hypothesis, we studied the peculiarities of demonstrating the group reliability of physicians and the features forming the concept of their group reliability – a comparative empirical analysis of the medical support group's reliability criteria was conducted.
The practical value of the research presented in this article lies in the fact that the ideas about group reliability gained during empirical-theoretical research are a methodological basis for developing social-psychological programs and training aimed at increasing the effectiveness of physicians' activities. This may be done by bettering group cohesion, improving the staff's communicative qualities, and harmoniously developing human resources.
This research also reveals an essential aspect of professional reliability that relates to the psychological effects of teamwork while working in a group, which tends to reduce team stress and aid in personal job functions. In this regard, let's note such aspects as:
• Psychological features of persons engaged in joint professional activities.
• Mechanisms of organizing work in a single psychological field take into account the different professional functions and individual characteristics of employees.
Keywords and phrases. Group reliability, sincerity, personal responsibility, awareness, work efficiency, emergencies.

EDUCATION IN THE CONDITIONS OF THE NEW CORONAVIRUS, TRAINING OF FOREIGN LANGUAGES IN THE DAYS OF PANDEMIC
They cannot stop me. I will get my education, if it is in the home, school, or anyplace. –
Abstract
In 2019 the spread of the new coronavirus in the world affected all spheres of life. The education sector suffered greatly as the shift to distance learning caused great psychological difficulties. Besides, the problem of technological equipment and access to the Internet arose. Many people around the world couldn't afford to use their computers or smartphones for distance education. The pandemic, however, was an opportunity to acquire new knowledge. In global lockdowns, people started to look for alternative methods for the teaching and learning process to continue. Thus, online learning became not an option but a necessity; people could acquire new knowledge without leaving home and spending resources.
In the course of our work, we conducted surveys among students, and with the help of research, discovered the effectiveness of teaching foreign languages in the context of a pandemic; we highlighted the role of foreign language knowledge in the modern era and studied the model of distance learning in the Republic of Armenia.
Keywords and phrases. COVID-19 pandemic, online learning, distance learning, foreign language teaching, distance education in Armenia.

THE EFFICIENCY OF ANTI-CRISIS MEASURES FOR OVERCOMING THE ECONOMIC CRISIS CAUSED BY COVID-19 IN RA
Abstract
Due to the coronavirus pandemic, the world economy has entered a phase of another crisis at a fairly rapid pace since the beginning of 2020. The COVID-19 crisis has governments worldwide operating in a context of radical uncertainty and faced with difficult trade-offs given the health, economic and social challenges it raises.
The economic crisis caused by the coronavirus pandemic is unique; it is difficult to predict its possible depth. Governments in almost every country in the world have tried, and continue to try, to find the right balance between saving lives and saving national economies. Many governments at all levels have reacted quickly, applying a place-based approach to policy responses and implementing appropriate measures in response to the COVID-19 crisis.
In general, the effectiveness of the anti-crisis measures taken by the Government can be preliminarily evaluated by analyzing the financial allocations volume and GDP ratio index and the range of beneficiaries of these measures.
The most effective way to overcome the current economic crisis is to inject sufficient liquidity into the economy, which will help avoid a sharp decline in both aggregate supply and demand; otherwise, the economy will inevitably end up in a long period of decline.
To overcome the economic crisis, the Government of the Republic of Armenia developed and implemented a number of anti-crisis measures, which did not stand out with high efficiency due to small allocations for anti-crisis measures well as due to the narrow range of beneficiaries.
Keywords and phrases. Economic crisis, coronavirus pandemic, anti-crisis measures, financial resources, efficiency.

CAREER DEVELOPMENT MANAGEMENT AT DOCTORATE
Abstract
The purpose of this paper is to introduce the importance of professional and transferable skills of the doctoral candidate, stimulate discussion about the impact and effective management of the doctorate in a context of reforms in the policies and processes of third-level higher education.
Training of professional skills gives some discussion in doctoral studies about the availability and acquisition of graduate skills at the previous levels of higher education. It is assumed that the applicant in a specific area should already have the set of skills that will be fully applicable to doctoral studies and will be satisfying for the full realization of the graduate's professional qualifications.
A doctorate graduate must have adequate professional skills in the areas of research, education, cooperation and teamwork, innovation, etc. and therefore should have the skills that can be transferred from science/research to pedagogy/education or from pedagogy/education to leadership. Thus, transferable skills are universal and are an essential tool for all aspects of the doctor's professional realization. This is why doctoral students are mostly trained in transferable rather than vocational/professional skills.
It is important to investigate the awareness of teachers and students at the universities related to the necessity to enhance creativity within and by the academic community. Therefore, today's educational programs are considered competitive, with the result that not only "academic" but also "creative skill" graduates. In this regard, special emphasis should be placed on the student's not formal but productive individual work to develop creativity, an innovation that is one of the requirements of the current Bologna process.
At present, universities are facing a challenge to revise the direction of providing educational services in such a way as to reinforce the employer-HEI bridge and the dynamic changes taking place in the labor market by taking into account. The involvement of future employer in the management processes of doctorate and career development is important.
A postgraduate student - PhD must demonstrate leadership skills in a working environment, directing the teamwork of large or small groups of employees to achieve effective outcomes. And if the traditional administrator guided the process in accordance with established organizational standards and norms, the doctor with a degree would show creative approaches here, trying to transform and develop the team management process, using his high professional qualities.
Keywords and phrases. Doctorate, career management, professional and transferable skills, doctoral candidate leadership.

COMPOUNDING IN THE WORK “ARMENIAN HISTORY” BY KIRAKOS GANGZAKETSI
Abstract
Various languages of the world have different word-formation. Depending on the stages of the language development, they may possess vivid or weakly displayed manifestations of word-formation patterns. The changes occurring in social life most of all influence the word stock of any language. Meanwhile, it is worth mentioning that word-formation models are stable; that is to say, both distinct words and word formation patterns may be transferred from one stage of the language to another.
The present paper touches upon the phenomenon of compounding and its peculiarities in the work of ‘History of Armenia’ by an Armenian historian of the 13th century Kirakos Gandzaketsi. The research covers in detail the approaches to patterns of compounding existent in linguistic literature, as well as all the types of compounds presented in the work of the historian, the compounding patterns with root words and linking vowels, any possible combinations of component stems belonging to different parts of speech.
Having analyzed the observations on the word-formation patterns of compounds in the researched work, we can conclude that they stand out due to their diversity. However, some disproportion in terms of their functional characteristics can be observed. There are patterns with the help of which tens of words can be formed, and there are patterns with only one example. Based on a comprehensive analysis of compounding peculiarities in Old Armenian and Middle Armenian, namely in the studied work, we can unequivocally state that the historian, being a representative of the Middle Armenian literature, mostly used word formation patterns of Old Armenian, applying all the types of compounding and various combinations of root words in his work.
Keywords and phrases. Kirakos Gandzaketsi, 13th century, “History of the Armenians”, compounding, word formation.

THE TRANSFORMATION OF A YOUNG FAMILY IN MODERN ARMENIAN
SOCIETY
Abstract
This article is devoted to the young family transformation of the contemporary Armenian community along with global economic influences, the causes and potential solutions of educational problems where the author has stressed the family organization as the key cell of society as a responsible for the mechanism of the formulation of an individual.
The modern family is going through a difficult period of its development. The young family firstly needs the support of the state. The scientific works devoted to the study of the family problems and family relationship, however, is not sufficient, as the institution of the family is different in different periods, as well as the needs and the mechanisms of satisfaction.
Based on the analysis of various educational structures, the author concludes that the family creates the foundations of ethical schooling and future youth and family formation development.
Monitoring different aspects of socialization of young people, which have a significant impact on the person formation, the author suggests using complex attitude, revealing the motivation and main issues for forming a family. Besides family, the state also takes responsibility. One should prove the quote: “solid family, strong motherland”.
Keywords and phrases. Family, youth, family upbringing, national traditions, globalization, communication, socialization.

The psychological manifestations of the armenian youth’s political activity
Abstract
A study was carried out to review the motives and manifestations of the political activity of the Armenian youth. The study involved 100 undergraduate and graduate students of the Armenian State Pedagogical University. The following varieties of the survey method were used: written survey - questioning; oral group survey – conversation. The data obtained were compared with the results of similar studies conducted with young people in Russia. According to the survey results, the majority of Armenian youth are interested in politics, but only a few believe that politics plays a significant role in their lives. Politically active youth are convinced that their demands can be heard in the public and political life of the country. The following motives condition the political activity of the Armenian youth: preserving the integrity of the Motherland, restoring the infringed human dignity, demanding the restoration of social justice, improving the economic situation of the country. Most young people do not have clear political preferences: their attitude is often conditioned by sympathy for the personality of the party leader, rather than knowledge of party programs. Young people's political activity is predominantly affective in nature: their attitude towards politicians is very emotional, the reasoning and analytical components are weakly expressed. Armenian youth has a subjective attitude to political events and gives opposite assessments. On the one hand, young people demand freedom of expression in their political behaviour, but on the other hand, they show intolerance towards dissent.
School and university education for teenagers and youth should contribute to developing a culture of conducting a civilized dialogue.
Keywords and phrases. Youth, political activity, subjective point of view, polar assessments, civilized dialogue.

QUALITATIVE MEASURES OF FAMILY FUNCTIONS AFFECTING CHILD DEPRIVATION
Specifically, the approaches proposed by Bowlby, Spence, Kadushin and Burnstein were discussed in the context of risk factors causing child abandonment. Besides, the concept of family resilience was studied as a new perspective on family functioning.
Even though there exists a range of diverse approaches in social sciences regarding family care deficiencies and child abandonment, there is still a need for additional studies to develop a more structured view of the phenomenon. Specifically, to extract the practical measurements of the classification of the phenomenon, both for research and practical purposes. In particular, a qualitative research was carried out based on the methodology of the grounded theory. In the frames of the research, about 282 registered cases of child abandonment were studied. The cases were classified into four main categories, according to the circumstance of becoming deprived of parental care: death of a parent, refusal of care, inability, or impossibility to take care of a child. As a result, it was possible to identify the essential factors that accompany each of these four circumstances and to highlight the key axes through which the guardianship vector passes.
The results of the article allow us to state that firstly, child abandonment is a multilayer phenomenon, that is why both the causes and impact of abandonment at least depend on social relations (child-parent, child-substitute parent, parent-substitute parent) and main components of deprivation (nature and quality of the relationship, circumstance of becoming deprived of care, nature of the action to deprive the child of care). Second, child abandonment takes place in cases when the above-mentioned risk factors intersect. Third, as a rule, abandonment is an intentional and voluntary action by the parent. And finally, the amount and quality of natural social ties are directly related to the outcome of child abandonment.
In addition to the findings, the proposed approach to the classification of the phenomenon of children’s deprivation from parental care in the previous article has been revised, which can be useful both from theoretical and research perspectives and have an active impact upon the policy development for children deprived of basic care.
Keywords and phrases. Childhood, childhood content, family functions, qualitative measurement of family functioning, care deprivation, child abandonment, social relations, grounded theory.

THE ROLE OF PUBLIC INVESTMENT POLICY IN THE FORMATION AND REGULATION OF THE INVESTMENT MARKET
Abstract
The development of a market economy in any country is impossible without systematic and effective market relations regulation. The public investment policy is the activity of state bodies and institutions aimed at influencing the investment market and redistributing the capital flows in favour of settling issues of public importance, as well as attracting investments to priority areas of economic development, defined in the relevant state programs for a certain forecast period with the account of the balance between private and public interests. The effectiveness of investment market regulation can significantly impact the overall effectiveness of the general economic policy. On the one hand, a developed investment market is necessary for the economic growth of the state. On the other hand, the active turnover of financial goods and services contributes to the development of business relations in the country.
Within the framework of state regulation of the investment market, the key role of public investment policy is to ensure the balance of private and public interests in the market, considering that personal interest is manifested in directing the investment activity to maximum profits. In contrast, the public interest lies in the state's strive to achieve socially effective results, using investments in transport, social, energy and other infrastructures.
The state carries out the function of creating a favourable investment environment in the country with the application of the active method, which is connected with the increase of the efficiency of the investment activity, as well as with the help of the tools of the method, which can be summarized as follows: ensuring favourable conditions for private investors, direct state participation in most efficient and significant investment projects for the country, application of internationally accepted criteria for assessing the financial efficiency of investments, such as current value, internal rate of return, repayment period, promotion of private sector investment through tax incentives.
Key words and phrases. State investment policy, investment market, efficiency, public interest, economic growth.
