PROTAC Design v1
Authors: not provided boc.protac
Published: May 2022

PROTAC (protein degradation targeted chimera) is a special protein degradation technology, which uses ubiquitin proteasome pathway, a natural protein degradation pathway in cells, to remove specific proteins that need to be degraded. A PROTAC molecule consists of two key domains: the domain that specifically binds to the target protein that needs to be degraded, and the domain that binds to the E3 ubiquitination ligase, which is linked by a specific linker. Unlike traditional small molecule inhibitors, which can only regulate the activity of target proteins, PROTAC can directly degrade target proteins through the protein destruction mechanism of cells themselves. Intracellular proteins with abnormal structure or function are labeled with polyubiquitin by a series of enzymes, which are then transferred to the proteasome for degradation. As a leading service provider in drug discovery and research, BOC Sciences is fully capable and committed to providing one-stop proteolysis targeting molecular drug discovery based on chimeric (PROTAC®). This has become a promising strategy in the field of drug discovery. With a comprehensive and advanced platform, we provide PROTAC molecular discovery package services to customers around the world to meet new drug discovery goals. This includes a variety of services that cover the entire process.
[RETRACTED] Peptide C-Terminal Modification v1
Authors: Miller Cathy
Published: May 2022

[RETRACTED]

The post-translation modification of eukaryotic proteins by the addition of isoprenyl lipids at their C-termini was first observed in the 1970s and 1980s. Since then, more than a hundred proteins have been shown to be modified by C15 farnesyl or C20 geranylgeranyl groups, including most members of the Ras, Rho, and Rab families of G proteins. The C-terminal of the peptide is synthesized as an amide to neutralize the negative charge created by the C-terminal COOH. This modification is added to prevent enzyme degradation, to mimic native proteins, and in some cases to remove hydrogen bonding at the C-terminal of the peptides which may interfere with the assays. Creative Peptides specialized in the custom synthesis of C-terminal modification peptides, providing a confidential and efficient service at competitive prices. Every step of peptide synthesis is subject to Creative Peptides' stringent quality control. Typical delivery specifications include HPLC chromatogram Mass spec analysis Synthesis report Certificate of analyses
Lexical Cohesion Patterns of Natural Science Academic Text and Implications for Lexical Teaching: Textual Analysis of IELTS Reading Passages
Authors: Wang Yi
Published: May 2022

With IELTS’s worldwide recognition as an accountable indicator of English proficiency level, scholars have investigated IELTS extensively to provide insights for ESL teaching. Despite the manifold investigation into the validity, typographical features, washback on candidates and practical knowledge of the reading test, little research is done to manifest its lexical cohesion patterns and pedagogical implications. To fill in the research gap, the researcher selected 20 natural science passages from IELTS reading passages and conducted textual analysis under Halliday and Hasan’s English cohesion framework. Pedagogical implications are revealed by combining research findings with a lexical-based teaching approach, lexical syllabus design and knowledge structure development in the subject matter. Research findings indicate that the lexical cohesion patterns of natural science passages share similar organisational structures with subject matter knowledge. Reiteration patterns establish a panoramic view and taxonomic framework of subject matter, whereas collocation patterns focus on detailed explanations, examples and contextual extension that can contribute to the accruement of real-world knowledge. Based on these findings, the study suggests that the teacher can integrate lexical cohesion syllabus into the traditional pre-reading, while-reading and post-reading teaching stages. Though limited in scope and validity, these findings can provide a framework of combined research between text analysis and teaching approaches. More empirical experiments can be followed up to undergird the efficacy of the suggested lexical syllabus and provide more detailed pedagogical insights.
A Cross-Cultural Study of Modality in the Speech Act of Asking for Permission
Authors: Tran Tien B.
Published: May 2022

This paper is concerned with a cross-cultural study of modality expressions in asking for permission by Vietnamese and English speakers. The study involved 209 Canadian and Vietnamese informants with the use of a Discourse Completion Task questionnaire. A total of 3000 utterances were chosen for analysis to gain insights into the frequency and types of lexico-modal markers manifested in the two languages. It is found that hearer-oriented verbal style tends to be dominant in Vietnamese while the speaker-oriented strategy is more favored in English. Vietnamese speakers tend to employ direct strategies with a dominant use of appealers which sounds intimate to the hearer. English speakers, by contrast, incline to conventionally-indirect strategies such as Can I, Could I, etc. It is also evident that Vietnamese speakers frequently use politeness markers when they communicate with the older, but they hardly use them for their peers. English speakers, however, use politeness markers for all partners with a slight variation. Another noteworthy similarity is that both Canadian and Vietnamese women modalize their language than men.
Translating Nure-Nure Texts in Karonese Society Into English: Applying Translation Techniques
Authors: Sembiring Milisi , Girsang Martina , Siregar Roswani
Published: May 2022

The aim of this study is to develop Molina & Albir’s (2002) translation technique in translating nure-nure texts of the Karonese language into English. The problems in the process of translating the source language (SL) into the target language (TL) are the equivalences of the SL in the TL. The data are collected from Suka’s (2014) book entitled Ranan Adat: Orat Nggeluh, Rikut Bicara Kalak Karo ope Tubuh seh Idilo Dibata. Conceptual research was applied to get the data while translation and critical discourse analysis were used to analyze the data. The authors translated twenty-two data samples from the SL into the TL. They used Molina & Albir’s (2002) translation technique to translate metaphors, stylistic repetition, a poem, politeness, and cultural terms in the nure-nure text into English. The study reveals ndu, -ta, and kam are polite pronouns in the Karonese language but they are not found in English. The translation techniques of adaptation, description, transposition, calque, generalization, literal translation, modulation, compensation, amplification, and borrowing were applied when translating the SL into the TL. The authors propose using the interdisciplinary translation technique to develop Molina & Albir’s (2002) translation technique as an alternative technique to overcome the problems of equivalences in a TL.
English Learning Demotivating Factors Among Non-English Majors in Medical University
Authors: Meng Yanzhi
Published: May 2022

Learning motivation is closely related to second language acquisition. Strong learning motivation can make up for the lack of language competence and poor learning conditions to a certain extent, while lack of motivation or demotivation will hinder language-gifted learners from achieving their expected learning goals. This study investigates the demotivating factors of learning English among non-English majors in medical university by interviewing 60 undergraduates. The findings show that the demotivating factors mainly involve the teachers, teaching contents, learning environment and the learners. The study further puts forwards some practical suggestions for stimulating and maintaining students’ learning motivation.

WATER SPRINGS OF VOLYN REGION, THEIR CLASSIFICATION AND SPATIAL LOCATION
Authors:   Lesya Ukrainka Volyn National University, Mishchenko O. , Fenko V. ,   Lesya Ukrainka Volyn National University
Published: May 2022

The scientific interest in the study of water sources is related to their recreational, environmental and sacred significance, as well as the prospect of use in the drinking water supply. The object of this study is the natural water springs of the Volyn region. The methodological basis is a combination of geographical and environmental approaches used in the investigation of the interaction of man and nature. The scientific novelty of the research is the application of a scientific approach to the study of water springs in the Volyn region not only as factors in maintaining water balance but also as objects of worship. The study of geological and hydrogeological preconditions for the formation of water springs in the Volyn region shows that the groundwater of the study area belongs to the bicarbonate class, a group of calcium mainly of the first or second type. The existing classifications of water springs are generalized and adapted to the conditions of Volyn region. The classification of water springs is made on the following features: the direction of water flow, the peculiarity of functioning, the nature of use, hydrological conditions, chemical composition and the level of sacredness. According to the results of the study, it was established that within the study area there were 81 functioning springs, 52 of which are consecrated. The spatial location of water springs in the Volyn region has been studied in the structure of physical and geographical areas. It is established that the largest share of them was formed in Verkhnoprypiatskyi (19), Liubomlsko-Kovelskyi (18) and Turiisko-Rozhyshchenskyi (15) physical-geographical districts. Some consecrated water springs of the Volyn region, which are used as objects of worship, are described, in particular in the villages: Telchi, Vorotniv, Hirka Polonka, Hremiache, Sokil. The widespread disappearance of natural water springs in the Volyn region is due to the natural and anthropogenic factors and is associated not only with their pollution, siltation, drying but also with the depletion of groundwater. In order to preserve and reproduce water springs, we advise continuing to work on their arrangement, to intensify the organization of operational and long-term forecasts of environmental change, monitoring of chemical and biological pollution, certification, and creation of protected areas within them.
Vernacular culture, city, architecture: analysis and correlation of concepts
Authors:   Taras Shevchenko National University of Kyiv, Kyiv, Ukraine, Butsykina Y. O.
Published: May 2022

The article is devoted to structuring the existing definitions of three key concepts within modern vernacular cultural studies in order to build a holistic picture of understanding the vernacular elements in urban space. Within the definition of vernacular culture (M. Lantis, A. Markusen, J. Carr and L. Servon), characteristics such as the combination of traditional culture and modern aspects of cultural identity in the non-professional dimension of city life were identified. Within the definition of the concept of vernacular city (J. Krase and T. Shortell, S. Sapu and others) the appeal to the discourse of everyday (G. Simmel, H. Lefebvre, M. de Certeau, R. Sennett and M. Blonsky) and the method of visual semiotics (R. Jakobson) is analyzed in order to distinguish signs of visual representation and urban identity, social and cultural conditions in the construction of urban space by its inhabitants. The concept of vernacular architecture (R. Brown and D. Maudlin, H. Guillaud, M. Salman) carries a combination of elements of traditional and everyday within postmodern and postcolonial studies and the concept of "collage city", as well as through the prism of the problem of sustainability.
The ways of developing a culture of education quality and academic integrity in the contemporary university
Authors:   Taras Shevchenko National University of Kyiv, Kyiv, Ukraine, Maslikova I. I.
Published: May 2022

The article deals with the analysis of the legislative provisions and regulations in the field of higher education in Ukraine and the regulatory framework of Taras Shevchenko National University of Kyiv. These legislative acts and regulations lay the foundation for the development of a culture of education quality and the corporate culture of the university. The study of the state of ensuring academic integrity within the framework of the AcademIQ project "Initiative for Academic Integrity and Quality Initiative", especially research of the interpretation of the survey of the teachers and students of Taras Shevchenko National University of Kyiv, allowed to outline the ways of developing a culture of quality in higher education, corporate culture of the university and academic integrity. The development of corporate culture and the quality of education at the university is associated with the articulation of the key values of the contemporary university community and the ethical virtues of all participants in the educational process. These values and virtues should be determined in broad discussions among students, teachers, and administration. The implementation of these values is possible through joint scientific, educational, methodological, cultural and social events, which can bring together all members of the university community. Teachers and students can internalize these values in different training courses. Ensuring academic integrity is possible through its procedural and institutional design. The important way for developing of academic integrity is raising awareness of all participants in the educational process through the increase of the content of internet sites, through broad discussions about complex cases of academic integrity, through the introduction of training modules into academic courses "Professional and Corporate Ethics", "Ethics", "Introduction on University Studies", "Academic Writing" .
Anthropology of victim in postmodern cultural practices
Authors:   Bogdan Khmelnitsky National University of Cherkassy, Pushonkova O. A.
Published: May 2022

The article examines the anthropological dimension of the victim phenomenon through the prism of Rene Girard's concept and modern studies of nihilistic tendencies of cultural scenarios with dominant polar psychotypes. The significance of Rene Girard's theory in the study of the archetypal basis of victim behavior, its historical sources and myth-ritual basis is studied. The cultural specifics of modern forms of counteracting victimhood and value contradictions of the victim's figure in the conditions of new threats to humanity, changes in the space of culture in the direction of increasing dependence on media communication platforms, are revealed. Some aspects of the victim's behavior have been linked to identity patterns which suggests a hedonistic-entertaining culture format that results in narcissistic choices or escapist behavior. The article clarifies the nature of the interaction between the images of the victim in the era of multimedia communication and cultural practices which acquire the character of a ritual response to the archaic internal conflict in the context of cultural-traumatic discourse. Examining the sacred nature of the victim in the processes of desacralization of modern culture, according to R. Girard, preservation and essential transformation of this defining archetype as a medium of aggression is concluded. In the modern scenarios a model of total victim is formed that has lost the function of channeling social aggression, falling into a vicious circle of destruction of either oneself or others (W. Kraus), or which is "stuck" in the "triangle of fate", where everyone is a victim (S. Karpman). A hedonist who suffers from shortcomings in a flat everyday life, having lost the tragedy of his own existence in the culture, acts as its repressed subject, but is not aware of it, according to the psychoanalytic theory of cultural trauma. However, in everyday practices (bullying, gaslighting, trolling) anyone can be a victim at any time. In a more global dimension, we are talking about the collective nature of sacrifice, as evidenced by the tendencies of radicalism, terrorism, war, genocide, etc. It is possible to eliminate human inherent aggressive instincts only through the step-by-step development of the value sphere (W. Kraus). This is the only thing that can prevent the self-destruction of the mankind and solve the problem of intraspecific aggression, which was considered from different points of view by K. Lorentz and R. Girard.
Essay: egyptological theme in the works of the Lesia Ukrainka
Authors:   Kharkiv State Academy of Culture, Soshnikov A. A.
Published: May 2022

Dedicated to the problem of modeling the image of Ancient Egypt in the work of Lesya Ukrainka as one of the popular areas of interests of intellectuals of the 19th – early 20th centuries. It was determined that the formation of this image is the result of her solid Egyptological knowledge, formed both through acquaintance with contemporary scientific oriental and Egyptological literature, and through direct study of the ancient Egyptian cultural heritage during her stay in Egypt and visiting its museums and ancient monuments. It is emphasized that the Egyptian essays by Lesia Ukrainka became the first attempt of Ukrainian orientalism to organize knowledge about the East on a Ukrainian mental basis. It is emphasized that the poetry of Lesya Ukrainka on Egyptian themes is the original artistic expression of her "History of the Eastern Peoples", in fact, the views expressed in it on the peculiarities of the development of ancient civilizations.

Published: May 2022

O presente trabalho teve como objetivo ajustar o modelo volumétrico de Schumacher-Hall por grupos de espécies e para um conjunto de 24 espécies, utilizando a análise multivariada, em uma área submetida ao Manejo Florestal Comunitário. Os dados utilizados são oriundos da Floresta Nacional do Tapajós, mais precisamente da Unidade de Produção Anual 10. Foi realizada a análise de Cluster e análise discriminante para verificar a veracidade do dendrograma formado. A partir do agrupamento foi ajustado o modelo volumétrico de Schumacher e Hall para os grupos e para todas as espécies que fizeram parte do estudo, com a finalidade de compará-los. Dentre os grupos, o que mais se destacou em volumetria foi o grupo III (Manilkara huberi; Couratari guianensis e Hymenaea courbaril), seguido do grupo II (Cordia goeldiana; Dipteryx odorata; Lecythis pisonis; Cedrela odorata; Diplotropis purpurea; Handroanthus incana; Vochysia maxima; Goupia glaba; Pseudopiptadenia psilostachya; Mezilaurus itauba; Terminalia dichotoma; Handroanthus serratifolius) e em terceiro o grupo I (Apuleia moralis; Pouteria bilocularis; Vatairea paraensis; Cedrelinga catenaeformis; Lecythis lurida; Hymenolobium petraeum; Bagassa guianensis; Hymenaea parvifolia; Astronium lecointei). O ajuste das equações apresentou diferença significativa apenas para a equação do grupo II quando comparados o volume estimado com o volume real, não sendo aplicável a equação geral para tal grupo de espécies. Os grupos I e III só apresentaram diferença significativa em relação a equação aplicada para todas as espécies. Com isso recomenda-se o ajuste por agrupamento de espécies, principalmente para florestas tropicais.

Authors: Alves Rafael Mateus , Silva Monalisa Alves Diniz da , Silva Elania Freire da , Silva Joyce Naiara da Silva
Published: May 2022

Os sistemas agroflorestais destacam-se por possibilitarem uma exploração ecologicamente viável das espécies envolvidas, tanto florestais como cultivadas. Pityrocarpa moniliformis se destaca como uma espécie florestal com alto valor apícola, o que viabiliza uma fonte de renda extra para os agricultores, já o milho é uma das principais espécies utilizadas como base alimentar, por ser fonte de carboidratos e proteínas. Dessa forma, são necessárias pesquisas sobre as possíveis interações estabelecidas entre as espécies florestais e cultivadas, tal como a alelopatia. Visto isso, objetivou-se identificar uma possível influência alelopática de folhas secas de P. moniliformis, em processo de decomposição, sobre o estabelecimento e o desenvolvimento inicial de plântulas de milho, variedade Ibra. Identificou-se através da caracterização qualitativa a presença ou ausência de alcaloides, triterpenoides, esteroides, saponinas, cumarinas, compostos fenólicos, taninos, flavonoides, antraquinonas, antocianidinas, chalconas, leucoantocianidinas, catequinas e flavononas, para o extrato aquoso de folhas secas de P. moniliformis. Além de verificar o estabelecimento das plântulas através da porcentagem, índice de velocidade e o tempo médio de emergência e o desenvolvimento inicial, avaliando altura da parte aérea, comprimento do sistema radicular e massa seca da parte aérea, do sistema radicular e total. O delineamento utilizado foi o inteiramente casualizado em esquema fatorial. Constatou-se no extrato foliar a presença de alcaloides, triterpenoides, saponinas, compostos fenólicos, taninos, flavonoides, antraquinonas, catequinas e flavononas, sendo elas substâncias com potencial alelopático. O cultivo do milho como parte integrante de um sistema agroflorestal em que haja a presença de P. moniliformis não é recomendado.

Published: May 2022

Objetivou-se avaliar a resposta dos teores foliares de macronutrientes na cultura do milho sob adubação nitrogenada de cobertura e efeito residual da coinoculação de Azospirillum brasilense na soja. Semeou-se soja com dois tratamentos, constituídos pela inoculação das sementes com Bradyrizobium japonicum com e sem a coinoculção com Azospirillum brasilense, sendo semeado milho na sucessão. Os tratamentos para a cultura do milho foram constituídos pela combinação da inoculação residual de Bradyrhizobium japonicum e a coinoculação residual com Azospirillum brasilense na faixa (fator principal) aplicados nas sementes da soja e cinco doses de N (0, 50, 100, 150 e 200 kg ha-1) aplicadas no milho segunda safra consorciado com Urochloa ruziziensis nas parcelas (fator secundário). Foi realizada determinação do teor foliar de N, P, K, Ca, Mg e S para cultura do milho. Foram realizadas as seguintes determinações: eficiência de utilização de nitrogênio (EUN), recuperação do nitrogênio aplicado (RNA), eficiência agronômica do N aplicado (EA) e eficiência fisiológica (EF). Os dados das avaliações foram submetidos à análise de variância, sendo que as médias do fator qualitativo (inoculação) foram comparadas pelo teste F e para o fator quantitativo (doses de N), foi realizado o estudo de regressão polinomial. O resíduo da coinoculação no milho não elevou o teor de N foliar do milho, porém houve incremento de forma crescente conforme a dose de N aplicada. Para os demais nutrientes quantificados (P, Ca, Mg), houve tendência ao incremento foliar desses nutrientes na maioria das doses em relação a coinoculação e interação entre os fatores inoculação e doses de N. Para K e S não houve incremento de acordo com o resíduo da coinoculação. A coinoculação residual com Azospirillum brasilense na soja promove melhorias na fisiologia do milho cultivado em sucessão, gerando plantas com maior potencial produtivo e maior potencial de tolerância a estresses.

Published: May 2022

Uma importante função da embalagem nos alimentos é a conservação do produto. Quando se trata de frutas, essa função é determinante já que os atributos visuais de qualidade (aparência e cor) são limitantes no momento da compra, e sofrem transformações rápidas após a colheita. Neste trabalho objetivou-se avaliar o efeito de diferentes embalagens (tereftalato de polietileno, embalagem ativa e biofilme de pectina) na conservação de morangos. As frutas foram lavadas e sanitizadas com hipoclorito de sódio, e posteriormente envolvidas pelas embalagens. Foi realizado um delineamento experimental 32, sendo que os fatores foram o tipo de embalagem e o tempo de armazenamento (3, 5 e 7 dias). Foram avaliados os parâmetros colorimétricos (L*, a* e b*), a perda de massa, o teor de sólidos solúveis e pH durante os períodos de armazenamento. O biofilme de pectina resultou em maiores variações do peso (29,03%), porém manteve as menores variações nos demais parâmetros avaliados. O fator tempo foi significativo (P ≤ 0,05) apenas para as respostas a* e b* da cor. Os resultados deste trabalho demonstram uma alternativa para melhorar a conservação dos morangos.

El objetivo del texto fue describir los beneficios a corto, mediano y largo plazo de la reforestación con fines comerciales en el departamento de Córdoba. Para lo cual, fue necesario tener en cuenta las diferentes variables tales como la vulnerabilidad del sistema financiero, las limitaciones en las tecnologías de punta, el ordenamiento forestal y la normatividad vigente. La metodología fue mediante la puesta en marcha de un modelo de valoración de empresas en Microsoft Excel adaptado para las unidades forestales, por medio de la realización de un ejercicio en el cual, se utiliza un modelo de simulaciones de Montecarlo, el cual permitió definir de un set de variables exógenas (explicativas) que se pueden obtener un resultado de valor patrimonial. Luego de la realización de la investigación teórica, la recolección de información y de la realización de tres simulaciones que propone el modelo Montecarlo permitió exponer que las diferentes variables afectan los rendimientos económicos de las plantaciones forestales; en las diferentes simulaciones se logró determinar que ellas ayudan a fijar los parámetros de tal manera que estos se encuentren en rangos de aumentos y disminuciones acorde a la realidad económica

Frente a la responsabilidad social de las organizaciones es escaso el análisis moral sobres su fundamentación, de allí que este artículo se basó en responder a la pregunta ¿cuáles son los argumentos morales que se identifican en las publicaciones y que dan soporte a la responsabilidad social de las organizaciones?  Partió de una investigación documental de corte cualitativo donde se realizó una abstracción discursiva del fenómeno para identificar nuevas tendencias y explicaciones. El principal hallazgo es la preeminencia de las posturas deontológicas sobre las consecuencialistas; esto se debe, entre otras cosas, por las obligaciones y deberes tanto legales como autónomas que se apoyan en objetivos sociales de la empresa.  La conclusión principal muestra la coherencia de este hallazgo con el proceder las empresas que establecen normas y protocolos como instrumento para el comportamiento de quienes integran la organización.

INTRODUCTION: Impaired renal function as seen in chronic kidney disease (CKD) is a known risk factor for coronary artery diseases and has been linked to inferior outcome after myocardial revascularization. Studies on the outcome of coronary bypass grafting (CABG) in CKD-patients are scarce. We aimed to study this subgroup of patients following CABG in a well defined whole-nation cohort, focusing on short term complications and 30 day mortality. MATERIALS AND METHODS: A retrospective study on 2300 consecutive patients that underwent CABG at Landspítali University Hospital 2001-2020. Patients were divided into four groups according to preoperative estimated glomerular filtration rate (GFR), and the groups compared. GFR 45–59 mL/mín/1.73m2, GFR 30-44 mL/mín/1.73m2, GFR <30 mL/mín/1.73m2 and controls with normal GFR (≥60 mL/mín/1.73m2). Clinical information was gathered from medical records and logistic regression used to estimate risk factors of 30-day mortality. RESULTS: Altogether 429 (18.7%) patients had impaired kidney function; these patients being more than six years older, having more cardiac symptoms and a higher mean EuroSCORE II (5.0 vs. 1.9, p<0.001) compared to controls. Furthermore, their left ventricular ejection fraction was also lower, their median hospital stay extended by two days and major short-term complications more common, as was 30 day mortality (24.4% vs. 1.4%, p<0.001). In multivariate analysis advanced age, ejection fraction <30% and GFR <30 mL/min/1.73m2 were independent predictors of higher 30-day mortality (OR=10.4; 95% CI: 3.98-25.46). CONCLUSIONS: Patients with impaired renal function are older and more often have severe coronary artery disease. Early complications and 30-day mortality were much higher in these patients compared to controls and advanced renal failure and the strongest predictor of 30-day mortality.

При строительстве новых базовых станций на сложных по рельефу загородных трассах, отдаленных и труднодоступных населенных пунктов Хабаровского края необходимо учитывать ослабление сигнала за счет лесных массивов. На примере уже существующего объекта связи проводится оценка распространения радиоволн для технологии GSM в диапазонах 900 и 1800 МГц. Проведен расчет затухания для трассы со сложным рельефом с учетом лиственного леса,его сравнение с фактическими показателями, а также результаты моделирования для хвойного и смешанного леса. Для решения поставленных задач используются методы математического моделирования, вычислительной математики, системного анализа, методы программирования и натурного экспериментального исследования.

When building new base stations on country roads with difficult terrain, remote and hard-to-reach settlements of the Khabarovsk Territory, it is necessary to take into account the weakening of the signal due to forests. On the example of an already existing communication facility, an assessment of the propagation of radio waves for GSM technology in the range of 900 and 1800 MHz is carried out. The calculation of attenuation for a path with a complex terrain, taking into account a deciduous forest, its comparison with actual indicators, and also the simulation results for a coniferous and mixed forest are presented. To solve the tasks set, methods of mathematical modeling, computational mathematics, system analysis, programming methods and full-scale experimental research are used.

The methods of managing the reliability of special-purpose equipment are investigated. The model of maintenance management (hereinafter referred to as the) of security equipment is considered, the model is tested on various values of system parameters. The task of optimizing the maintenance of equipment is formulated in the form of an optimal control problem. Using explicit difference schemes, a discrete optimal control problem is constructed, for which the necessary optimality conditions are formulated. Taking into account the obtained relations, an algorithm for numerical solution of the problem by gradient methods is proposed.
