The Molecular dynamics simulations of the mechanical behavior of nanostructured and amorphous Al80Ti15Ni5 alloy
Authors: Melhorance Barboza Alexandre , Napoleão Bastos Ivan , Rodríguez Aliaga Luis César
Published: October 2020

Classical deformation mechanisms based on crystalline defects of metallic polycrystals are not entirely suitable to describe the mechanical behavior of nanocrystalline and glassy materials. Their inherent complexity creates a real challenge to understand the acting physical phenomena. Thus, the molecular dynamics approach becomes interesting because it allows evaluating the mechanical properties and its related atomic structure. To study the atomic structure's influence on the deformation mechanisms at the nanoscale level of the Al80Ti15Ni5 alloy, molecular dynamics simulations, and post-processing techniques were used in the present work. The results revealed a significant dependency between the Young modulus and the atomic structure. Moreover, the type of structure, i.e., nanocrystalline or amorphous, governs the deformation mechanism type. For the nanocrystalline alloy, grain boundary sliding and diffusion seem to be the dominant deformation processes followed by the less essential emissions of partial dislocations from the grain boundaries. Concerning the amorphous material, the shear transformation zones begin to form in the elastic regime evolving to shear bands, these being the main mechanisms involved in the deformation process. The results also indicate the amorphous structure as a lower limit-case of the nanocrystal. The Al80Ti15Ni5 elastic moduli values were below expectations; for this reason, the effects of unary and ternary interatomic potentials were evaluated for each element.
The Research Topics of Leadership: Bibliometric Analysis from 1923 to 2019
Authors: Samul Joanna
Published: October 2020

Leadership phenomenon is characterized by unflagging interest among scientists in the field of management. This is one of the reasons why various theories, concepts and topics of leadership are propounded in literature. The current paper examined the trends of leadership publications, the most common topics of leadership, and whether the research topics have followed a coherent progression. A literature review was conducted in order to understand what has been done until now. Using a bibliometric analysis, the current paper summarized 12,235 publications on leadership from the Web of Science database, spanning the period from 1923 to 2019. The findings obtained indicate growing number of leadership publications and the following research topics: leadership management, leadership performance, leadership model, leaders' behaviors, leaders' personalities and team leadership which are related to each other. Moreover, the results also show a weakening interest in 'hard' aspects of leadership in a 'soft' direction.

To the question of modern problems of media (on the example of relations between citizens and bank employees).
Authors:   Voronezh State Technical University, Association of mediators «NOM», Popov Petr Petrovich
Published: October 2020

This article discusses the prospects for the development of mediation practice in the banking sector. The main task of mediation is to develop cultural negotiations. Examples of the effectiveness of mediation as the main path to social stability in this area, to create a conflict-free living environment, the ability to negotiate are given. Mediation is shown as a negotiation process used in complex or conflict situations. Therefore, it can have the widest application. The conflicts that mediators have encountered and have experience working with during mediation are quite extensive. In the socio-economic and political spheres; in the trade and financial sphere, it is possible to single out conflicts typical for other firms or enterprises; there could be conflicts in state administrative institutions similar to those in enterprises. Modern industries are becoming customer-oriented, which means the constant attention of specialists of different professions to human satisfaction. It is shown that alternative methods for resolving disputes can become an effective tool for resolving conflicts in economic circulation. This institute operates in various foreign legal systems. It is assumed that in Russia it will develop. The bank mediation we are considering is a timely and worthy alternative in resolving disputes arising in the field of banking legal relations. In this paper, relations and disputes between banks and their customers - legal entities and individuals concluding loan agreements are examined. This area is very relevant, as one of the real sectors of the economy is involved here - small and medium-sized businesses and individuals, who make up the bulk of borrowers in the banking services market. An analysis of the literature data on the problems and research methods showed that the advantages of mediation are the speed of dispute resolution and the informal nature of its settlement. The question is posed: Who is best suited for the role of mediator in the banking sector? It is shown which risks are important to consider when introducing mediation in the banking sector. Explains why mediation is preferable to litigation. In mediation, work is underway with the emotions of a person, as well as at the level of understanding and adoption of agreed decisions by representations of the dispute by the parties themselves, partnerships and trusts are being established. In order for subjective prerequisites to be fulfilled regarding the implementation of mediation, it is important to increase the level of awareness of people with a banking profession about the possibilities of mediation as an effective tool for resolving disputes.
Legal Linguistic Approach to the Study of Criminogenic Communication Polycode Texts in the Digital Environment in order to Ensure Information (Worldview) Security
Authors: Nikishin V. D. , Galyashina E. I.
Published: October 2020

In order to counteract the spread of aggressive polycode texts in the Internet environment, a legal linguistic approach is required: the legal regulation of counteracting “speech” offenses should be based on a comprehensive study using special knowledge from the field of judicial speech, integrating the provisions of linguistics, social psychology, psycholinguistics, cognitive science and other sciences speech cycle. The authors examine (from the point of view of substantive law and judicial speech) the main speech actions that constitute a threat to the worldview security of communication in a digital environment and are implemented through the generation of polycode texts. The paper proves that the concept of a “multimodal text” is not equivalent to the concept of a “multicode (creolized) text”, because the selection of data from linguistic entities is based on different criteria: sensory modality and communication channel. The classification of communication channels proposed by the authors, the types of relations between the verbal and iconic components of multicode texts, and other abstracts of the paper are the starting points for further legal and linguistic research of criminogenic Internet communication that threatens information (worldview) security in the aspect of judicial linguistic examination.
A Criminal-Procedural Form: Essence, Problems, Trends and Prospects of Development
Authors: Rossinskiy S. B.
Published: October 2020

The paper is devoted to the most general issues of theory and legislative regulation of the criminalprocedural form—the necessary attribute of proceedings in a criminal case. On the basis of a procedural understanding of the criminal-procedural form, distinguishing it from formalism as a negative phenomenon in law enforcement practice, the author concludes that the criminal-procedural form serves a high purpose predetermined by a set of legal guarantees ensuring the effectiveness and high quality of criminal case results. At the same time, the author considers the most important legal properties of the criminal-procedural form: unity, universality, obligatory nature. The author also analyzes related problems arising in lawmaking and in the activities of the preliminary investigation bodies, the prosecutor’s office, the court, the bar and other persons involved in criminal proceedings. The results of the study allowed the author to give his own definition of the criminal-procedural form, determine the main tendencies and outline the prospects for its further development in the context of finding a reasonable balance between the public interests of the society and the state, on the one hand, and the rights of an individual, on the other.
Necessity to Reject Pre-Trial Inquiry as a Procedural Form of Investigation
Authors: Malysheva O. A.
Published: October 2020

A comparative legal analysis of procedural forms of inquiry and preliminary investigation leads to a conclusion about their similarity, as well as the similarity of procedural statuses of an investigator and interrogator (a person conducting an initial inquiry). This shows that the State distributes forces and resources in the field of criminal justice irrationally. At the same time, the existence of two similar forms of investigation does not lead to an improvement in the legality and quality of criminal cases investigation. On the contrary, this contributes in some cases to their deterioration (reasonable timing of proceedings in criminal cases, compensation of damage caused by crimes to victims), as confirmed by the data provided in the paper. The consolidation of similar procedural forms of investigation in the Code of Criminal Procedure of the Russian Federation proves that the national historical experience of the organization of investigation of crimes under the 1864 Charter of Criminal Proceedings is ignored. This means an unreasonable refusal to reform criminal proceedings, the necessity and directions of which were identified by the 1991 Concept of Judicial Reform of the RSFSR . The consequences are manifested in the narrowing of procedural guarantees of the right to protection of persons whose criminal cases are investigated in the form of an inquiry; in the forced violation of the rule of law by interrogators during investigation of criminal cases when initiating a criminal case on a non-obvious crime; in delaying proceedings in criminal cases initiated and investigated initially by interrogators and then for a number of reasons referred to investigators for further investigation, etc. These problems cannot be solved by constantly improving the legal regulation of the procedural form of inquiry. The written above testifies futility of the procedural form of inquiry, justifies the necessity of its elimination from the Russian criminal proceedings as an independent form of investigation.
Legal Aspects of Arms and Defense-Related Products Transfer between the EAEU Member States: Towards the Formation of an Arms Market?
Authors: Slepak V. Yu.
Published: October 2020

Treaties do not directly regulate the functioning of a single arms market in the post-Soviet space. However, an analysis of the provisions of the Treaty on the Eurasian Economic Union and agreements adopted within the framework of the Collective Security Treaty Organization leads to the conclusion that, in general, the existing legal framework contributes to the formation of similar (comparable) and the same type of regulatory mechanisms in this area based on market principles and application harmonized or unified legal regulations. The EAEU Treaty predominantly forms a general framework for the movement of goods and its possible restrictions, while detailed rules aimed at creating harmonized norms that exclude the need to resort to exceptions to the free movement of goods are created already at the CSTO level. In fact, the CSTO plays the role of an "agent" of the EAEU in terms of regulating economic issues of military integration, creating conditions for the opening of arms markets. The legislation of the Russian Federation uses two competing approaches to the functioning of arms markets. A restrictive one allows closing the national market for public safety reasons without any additional justification (it is used in the legislation on arms export and on state defense orders). A broad one, allows the market to be closed in exceptional cases (applies when the supply of goods is not directly related to defense and security issues).
Legislative Approaches to Addressing the Issue of Genetic Discrimination in Insurance
Authors: Suvorova E. I.
Published: October 2020

Genetic testing is a very attractive source of information for insurers, who often associate this opportunity with improving the risk assessment of personal insurance, as it is a key factor in determining whether insurers are willing to offer coverage to a particular individual and at what price. At the same time, statements are increasingly being made about the possibility of discrimination against policyholders and insured persons due to the expansion of the practice of using such information, which required the adoption of appropriate legislative decisions by a number of countries, although it is too early to talk about the formation of a systematic approach to solving this problem. An analysis of the legislation of a number of states revealed several approaches to solving this problem. The author highlights the countries that have established a complete ban on the use of genetic information in insurance (Austria, Norway, France), including in the context of protecting the rights to protect personal data of third parties (Spain, Portugal), as well as differentiated conditions for the use of genetic data depending on the amounts insurance coverage for life insurance, accident insurance (including at work); on the specific circumstances, determined by the legislator, and the reasons for the genetic study (Switzerland); from the participation of the insured in the program for the detection and prevention of congenital diseases (Israel).
Preliminary Constitutional Review and its Implementation in Russia: Problems of Theories and Applications
Authors: Brezhnev O. V.
Published: October 2020

The paper is devoted to the problems concerning the legal nature, normative regulation and the procedure for the implementation of the institute of preliminary constitutional review in the Russian Federation. Although the exercise of this type of constitutional control ensurs the prevention of the detected violations, it also carries certain risks associated with the limited time frame of its implementation, impossibility of taking into account interpretation of the contested norm in law enforcement, etc. The author demonstartes permissible forms of the use of preliminary control in the activity of the bodies of constitutional justice in Russia (when checking the constitutionality of international agreements and treaties of the Russian Federation, evaluating constitutional amendments, etc.). The author also investigates the practice of implementing the relevant powers. Particular attention is paid to the analysis of the legal positions of the Constitutional Court of the Russian Federation that stipulate the limits of the implementation of preliminary judicial constitutional review. The paper examines the issue of the powers of constitutional (charter) courts of constituent entities of the Russian Federation in the area under consideration.

K.L. in childhood he endured scarlet fever, but generally enjoyed good health, studied well in the village school, lingering actively helped his father in village work; character was good-natured, apathetic, played the violin well and was considered a good musician. He led a correct lifestyle, did not drink and, as far as is known, did not have sexual intercourse. I got sick in December 1895; according to the opinion of the patient's brother, the disease developed as a result of two reasons; K.L. was a witness of how the worker got into the car and was taken out dead; this circumstance seemed to have made a heavy impression on K. L; the second reason: he wanted to get married, but the father did not allow this the son must learn some trade, get a job and then get married. Around Christmas 1895 K.L. I was extremely apathetic, "quiet", slept a lot; sometimes complained about the feeling of pressure in the head and chest. At the end of January, he stopped talking, working and playing the violin, and slept almost all day long. The patient was used by a local doctor, but without any success; all manifestations of the disease progressively intensified. Before admission to the clinic, he almost continuously merged for two or three weeks, occasionally smiling: except for yes and no, he did not say a word. He himself went up to the table and ate, was clean; if he is taken somewhere, he resists. There was no deception of feelings, no inclination to destruction.

There is not a single poison, not a single infection that would produce such a variety of changes in the body as syphilis. Not a single organ is guaranteed against this terrible scourge of modern humanity. More syphilis does not spare the central nervous system, which, thanks to the modern conditions of life, is a locus mi-noris resistentiae. Damaging this organ, it produces an extremely variegated picture of both pathological and anatomical changes and clinical manifestations and course, depending on the diversity of the nature of the process, very different localization, speed or slowness of development.

The Sars-Cov-2 (COVID-19) pandemic has created unprecedented challenges, and revamped the way we live and work. Overall, this pandemic and its isolating consequences has forced societies to become more creative and develop new ways to engage. Professionally, employees are more secluded with attempts to work from home, while in the medical community, physicians have needed to either be on the frontlines treating patients or have adapted to interacting with patients virtually. Even with today’s technological advances to virtually connect with patients, physicians have had to relearn and re-engage.

Transformative learning – An educational perspective potentially contribution to radical and comprehensive change in Vietnamese higher education
Authors: Bui Thi Ngoc Linh , Tran Duc Tuan
Published: October 2020

The “Globalization 4.0” has challenged Vietnamese Higher education to meet the new requirements of generating qualified labor force: self-direct their learning and make their own decision, to adjust and develop their perspectives and their actions consequently. The current teaching and learning approaches mostly based on behaviorism are not enough to allow Higher education to achieve the new objective. Meanwhile, though constructivist learning has been implemented for years, its use was limited to activate student learning and equipped them with professional skills and competencies instead of focusing on developing their perspectives and worldview. To enhance the success of higher education in terms of achieving new educational objective, this paper will introduce transformative learning as a perspective that would be contribute to radical and comprehensive change in this educational level.

Reasonable Pumping Depth for Drainage and Gas Recovery of Shale Gas Wells
Authors: Chen Jianda , Wang Dajiang , Zhang Zhiquan , Liu Jie
Published: October 2020

For shale gas wells, in the initial production stage, the liquid production is large, and the lifting process is needed to assist the drainage. However, for gas wells, especially shale gas wells, the ultimate purpose is different from that of oil wells, and the current design method of pumping depth cannot meet the field requirements. Starting from the production characteristics of liquid-producing gas wells, this paper analyzed the gas well productivity, wellbore pressure distribution and critical liquid-carrying flow, and adopted the node analysis method to propose a design method for the pumping depth of shale gas wells during drainage and gas recovery. Then, the proposed method was applied to optimize the design of the jet pump of well A in Block JY, according to the design results, the pump was started for production; after the wellbore liquid level was raised to the designed depth, the gas well can conduct annulus space liquid-carrying production, and the production effect of well A showed that, the proposed method can be applied as a method for optimizing the technological parameters of shale gas wells.
Natural Convection Cooling of a Heat Source Placed at the Bottom of a Square Cavity. Effect of Source Length, Position, Thermal Condition and Prandtl Number
Authors: Horimek Abderrahmane , Nekag El-Amria
Published: October 2020

Cooling process of a heat source placed at the bottom side of a cold-walled cavity (TC) by means of natural convection has been studied numerically in this work. Two thermal conditions have been assumed at the source (q-imposed or T-imposed). The effects of Rayleigh number (Ra=10+3→10+6), source length (SL=0.1→1.0), source position (D) compared to left side, in addition to the effect of the number of Prandtl (Pr=0.71→10+2) were analyzed with ample details. For a source at the center of the bottom side, results showed an increase of flow and temperature disturbance with increasing Ra and/or SL, with an enhancement of both local and mean Nusselt numbers. Particular exceptions were noticed for high Ra values for the second heating type. For all considerations, the case of SL=0.1 makes an exception where a very good heat exchange rate is recorded. When the source is no longer centered, Clearer difference between this case and the previous one was recorded, especially for small D values. Very good heat exchange rate is recorded for D=0.0 for all considerations, with remarkable amount of difference compared the closest one to it, followed by a progressive decrease until the case of source at the center. Finally, Prandtl number (Pr) effect analysis showed an increase of the heat transfer rate with a clear amount from Pr=0.71 until Pr=5.0, followed by a slight increase for higher Pr values until stabilization for Pr>50.0. The good exploitation of the intervening parameters’ parameters, allows ensuring the best cooling of the source.

Published: October 2020

Este estudo visa discutir teoricamente a adaptação de estudantes à Universidade considerando variáveis psicossociais que a literatura tem mostrado estarem associadas à permanência de estudantes universitários na Instituição de Ensino Superior. Há estudos que indicam que além da importância econômica e vocacional, a universidade é local de aprimorar o desenvolvimento pessoal, obter mudanças de atitudes, valores, desenvolvimento de carreira e qualidade de vida. Entretanto, a transição do Ensino Médio para o Superior, embora traga benefícios aos alunos, pode trazer também vivências negativas, considerada por alguns como geradora de momentos críticos. São apresentadas e discutidas, com isso, variáveis relacionadas à adaptação à Universidade: as habilidades sociais (comportamentos necessários para uma relação interpessoal saudável de acordo com os parâmetros de cada cultura), a adaptabilidade à carreira (o equilíbrio almejado entre o trabalho e vida pessoal) e a maturidade profissional (conjunto de comportamentos que visam a escolha profissional de forma madura e consciente).
Velhice e saúde mental: desafios interseccionais para pessoas em situação de rua
Authors: Menezes Kelly Maria Gomes , Ferreira Sílvio Rodrigo Alves
Published: October 2020

Este artigo objetivou refletir sobre a vivência da velhice para pessoas que estão em situação de rua e como a saúde mental é vista nesse processo de envelhecimento. Como estratégias metodológicas, foi utilizada a pesquisa qualitativa em consonância às pesquisas de tipo bibliográfica, documental e de campo. As técnicas empregadas foram a observação e a entrevista aplicada a 2 (dois) sujeitos idosos em situação de rua, cujos relatos foram analisados com base na história oral. Através dos resultados, constatou-se que a saúde mental é uma política pública pouca acessada pelas pessoas que estão em situação de rua e que é imprescindível buscar novas estratégias de cuidado. Outro fator relevante percebido foi a ausência da intersetorialidade no cuidado à saúde para essa população. Por fim, observou-se que, para idosos entrevistados que se encontram nas ruas, existem diferenças perversas de se viver o envelhecimento, cujas consequências se dão em diversas dimensões de suas vidas, como: social, cultural, emocional, de saúde, entre outras. É, portanto, imperativa a necessidade de investimentos em políticas públicas para esta população, a fim de promover inclusão social e suas proteções pautadas em várias legislações vigentes.

Published: October 2020

Os saberes docentes e o seu caráter dialético têm chamado a atenção dos estudiosos da educação. O problema tratado nesta comunicação transita em torno da realidade da formação docente no Brasil e da articulação dos saberes desse grupo social com a sua prática profissional. A questão norteadora que se impõe é:  como os saberes docentes se articulam, e quais as suas implicações na práxis? A metodologia utilizada é de abordagem qualitativa e utiliza técnicas da história oral. O arcabouço teórico que sustenta o estudo se apoia no debate sobre formação de professores, sem prejuízo dos demais que complementam o referencial. A pesquisa, quanto ao seu objetivo, é descritiva, haja vista demonstrar a articulação dos saberes docentes em uma referida realidade escolar e os seus impactos no cotidiano daquela comunidade. Entre outros achados, percebemos que o cenário local encontrado se aproxima do que é descrito na revisão da literatura, que subsiste a representação do docente vocacionado, imbuído de uma tarefa para a qual afirma a necessidade de uma habilidade sobrenatural, inata, atribuição essa comumente reforçada pelos demais sujeitos da escola.

This study aims to investigate and evaluate the mechanism action of cowanin, a cytotoxic xanthone isolated from ethanolic extract of the stem bark of asam kandis (Garcinia cowa Roxb). This compound was isolated after successive column and radial chromatography to give a yellow needless crystal, m.p. 121-124 oC. Based on ultraviolet, infrared, mass and nuclear magnetic resonance spectroscopic data and comparison with those of the literature, this compound was elucidated as cowanin. Since it had activity against T47D human breast cancer cell lines, further investigation of its mechanism activity was performed to explore the effects of cowanin on cell viability, migration of cells, and the cell cycle activities against T47D breast cancer cells. Viability of cell was carried out by using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay, migration of cells by scratch migration assay, and the cell cycle analysis by flow cytometry method. As a result of this investigation, it can be seen that cowanin could inhibited T47D cells' growth at concentration 0.1, 1, 10, and 100 µg/ml at 48 hours with the IC50 value of 11.11 µg/ml. Cowanin exhibited inhibiting the cell migration T47D cells at concentration 11.1 Î¼g/mL treated cells at 48 h was 0.32 fold compared to control, suggesting the potent inhibitory effect of it. Cowanin is caused in significant detention of T47D cells at the G0-G1 phase of the cell cycle. Based on these data, it can be concluded that cowanin is a potential candidate to be developed as an anticancer drug.

This paper compares the robust and E-Bayesian estimations of the shape parameter for Burr XII distribution. BurrXII distribution was already reviewed by many researchers, as this distribution has gained special attention in recent times due to its complete applications, including the reliability field and failure time modeling. Burr distributions include 12 types of functions that produce a variety of probability density forms. We used two loss functions, quadratic, and LINEX with the E-Bayes method. The comparison conducted by simulation technique, and the absolute mean square error was measured to test the estimation methods' preference. In this study, many familiar distributions methods such as Weibull distribution, exponential logistic distribution, generalized logistic distribution, extreme value, and uniform distribution have been discussed accordingly by employing special cases and belonging to Burr distribution family. The current is dealing with the Bayesian method by depending on the parameter c that must be chosen to be close or not far from parameter b to ensure the robustness of the Bayesian estimator. Then the Bayesian expected of the parameter Î² under a quadratic loss function. It has been compared estimation for Burr-XII distribution by using the mentioned methods. We found many essential points, such as Robust estimates, in all cases, tend to be more efficient than the Bayes estimates. Also, by increasing the sample size, the robust estimates are still better than other estimation methods. When increasing the sample size, we notice a decrease in MAPE, which supports the statistical theory. We recommend using non-parametric methods to estimate Burr XII parameters. Thus, the main conclusion is that the robust process was the best.

In 2020, it is projected that the number of households in the Kepulauan Mentawai  Regency will reach 22,534 units in which 9,471 units have received electricity from the State Electricity Company (PLN). By the end of 2020, as many as 1,244 households will be targeted to get electricity from the bamboo biomass power plant that has been built. Thus until the end of 2020, there were still 11,819 household units that would not yet get electricity. The Kepulauan Mentawai  Regency Government targets that by the end of 2035 all households will have electricity, by developing electricity using bamboo biomass raw materials. The number of households in the Kepulauan Mentawai  Regency until the end of 2035 is projected to be 28,639 units, of which from 2020 to the end of 2035, there will be 17,924 household units including electricity needs. If each household is targeted to get 450 VA power, then the total electricity power still needed is 8,066 KVA or approximately 70,758,160 kWh/year. The bamboo biomass power plant, which will be operated in the Kepulauan Mentawai Regency, currently requires 1.5 kg of dry bamboo to produce 1 kW power with a power factor (ghospi) of 0.8. Thus the need for bamboo for power plants is approximately 132,484.1 tons/year. Therefore, to provide this bamboo supply, approximately 714 ha of bamboo is needed.

Working memory (WM), a central component of executive function (EF) which facilitates the capability to store and modulate information, develops rapidly during early childhood, and has proven to contribute to children's academic achievement. WM generally has two types of measures, each of which mainly involves the WM's verbal and visuospatial aspect. However, research on the standardized and developed assessment of WM aspects for early age children in Indonesia remains inadequate, especially embedded with information technology. This study aimed to develop a WM measurement tool using a computer-based application test to support the integration between the computer-based and behavioral measurements of WM aspects in early age children. Construct validity of the WM computerized test was determined by comparing the conventional and computerized EF tests on 36 children (15 boys and 21 girls) age 48-72 months old. Two computerized WM tasks that specified WM's verbal aspect, namely the Backward Animal Task and Shining Star respectively, were administered individually to each child by a trained tester. The Spearman correlation analysis resulted in Shining Star as the most suitable computer-based WM task for early age children. Both conventional and computer-based measures of the visuospatial aspect of WM had similar task mechanisms and rules. They equivalently required visual and kinesthetic modalities, which emphasized the common nonverbal aspects of WM. This result provides an initiative for the evidence-based development of the computer-based WM test in Indonesia for early age children, which is critically important to help individuals with psychological and behavioral problems during Covid-19.

Relevance. Development of valuable sterile lines of sweet pepper using nuclear-cytoplasmic male sterility is associated with the search for stable sterility maintainers in collection material.

Material and methods. The purpose of the research is to optimize the identification of the desired genotypes and accelerate the development of sterile lines using artificial climate chambers. The research material was a sterile line msTol55, which under the conditions of a film greenhouse showed partial fertility at the beginning or at the end of the growing season. The place of cultivation is artificial climate chamber, a film spring greenhouse.50-day-old seedlings were planted in pots on 10.01, the period of growing plants in the chamber - until 20.04, then the adult plants were transplanted into a spring film greenhouse. According to the traditional technology, the cassette seedlings of the same line were planted in the greenhouse on 15.04. The number of tested plants is 16-20 pcs. Growing mode in the chamber: 12 hours were illuminated with DRLV lamps, while the temperature was at the level of 26-28°C, from 20.00 to 8.00 the lamps were not illuminated, the temperature was 14-15°C. The actual sterility / fertility of the flowers was determined by the level of contamination of the fruits at the beginning of their formation.

Results. The maintained temperature regime for growing in an artificial climate chamber made it possible to identify sterile (30%) and partially fertile plants (70%) in the first 2 weeks of flowering. When adult plants were transplanted into a spring greenhouse, the number of sterile plants increased to 56%. When growing the line msTol55 in a spring greenhouse using the usual technology, partial setting of seeded and little seeded fruits on 60% of the plants was observed from the third decade of May to the second decade of July, then all plants set only non-seeded fruits. Based on the results obtained, it is advisable to identify the breeding material for the Rf gene in the ACC, since the proposed growing regime serves as a provocative background and allows for more effective control over the manifestation of sterility.
