SCO 20 years: key achievements and the role of China
Authors: Shkvarya Lyudmila V.
Published: October 2021

The article analyzes the process of development of the Shanghai Cooperation Organization (SCO) in the historical aspect and its current state. SCO was created as a regional association to maintain stability and security. Today, China is stepping up its efforts to boost regional economic cooperation.
Based on the analysis of UNCTAD statistics for 2001-2019, the authors justified the conclusion that the economic potential of the SCO has significantly increased. However, this growth is not related to the economic interaction in SCO, but with the expansion, and with the growth of the individual countries’ economies, primarily the PRC. 
The analysis confirms, that the share of bilateral trade and the volume of mutual (especially Chinese) investments in the SCO are growing. International cooperation in certain areas has little real support at the level of the Organization as a whole. At the same time, the existing successes of the SCO countries in the economic sphere, the attraction of significant foreign investment and modern technologies, the gradual diversification of national economies, as well as new initiatives of the People's Republic of China, determine the deepening of economic cooperation, the mechanisms of which are of scientific interest.
The relevance of the study is determined by the need to study the peculiarities of the SCO evolution and the positions of individual countries in SCO. The study makes a significant contribution to the understanding of the nature and features of the processes of economic cooperation and development in the region and the positions of individual countries.
Participation of Tanzanian tribes and tribal chiefs in the 19th century slave trade
Authors: Ivanchenko Oxana V.
Published: October 2021

This article summarizes the results of three field studies conducted in Tanzania in 2018–2020 by A.A. Banshchikova, O.V. Ivanchenko and V.N. Bryndina. The research focused on Tanzanians’ memories about the 19th century Arab-Swahili slave trade and its possible impact on the contemporary interethnic relations in the country. More than 160 formal and informal interviews in English and Swahili were taken in Dar es Salaam, Bagamoyo, Kaole, Tanga, Pangani, Zanzibar and several other locations. The choice of informants was carried out maintaining representativeness of the sample by the education level, gender, age, confession, ethnicity.
This article highlights the participation of Tanzanian chiefs in the slave trade. Respondents were asked whether tribal chiefs and tribes took part in this business; which tribes and chiefs were involved; what was their motivation; do these memories affect nowadays interethnic relations in Tanzania.
It turned out that Tanzanians do not express negative attitude towards local tribes and chiefs involved in the slave trade; moreover, their involvement is often presented as enforced (due to the fear of Arabs, who possessed more modern weapons, or as a result of their dishonesty). Meanwhile, the engagement of Arabs in the slave trade is well known; there are some tensions in the relations between Afro- and Arab-Tanzanians, including those related to history. Talking about renowned persons involved in the slave trade, respondents often named chiefs famous for resisting German colonization. For them the story of resistance to colonial rule and gaining independence remains much more important than the memory of the slave trade.
Caucasian Albania and the “Gates” in the Caucasus: Caspian, Albanian and Alanian
Authors: Alikberov Alikber K.
Published: October 2021

The article dedicated to the Caspian, Albanian and Alanian "gates" in the Caucasus continues the series of publications by the authors on the topic of the historical onomastics of Caucasian Albania. The focus is on the problem of mixing the names of the Caucasian "gates" - the most important mountain passes on the main routes of movement in antiquity, due to the common origin of the names Aluan and Alan from the old root *’äle- meaning“king, prince, lord”. This problem, typical for sources of various origins - Greco-Roman, Armenian, Arab-Persian and others - is solved on the basis of these sources themselves, including using data from the Albanian palimpsest, in which the word alye is directly recorded in the meaning of ‘senior; ruler'. An equally important task is the closely related interpretation of the contexts of reference and the possible localization of the "gates" in the Caucasus. The analysis of the sources made it possible to clarify some of the prevailing views on the locations of mountain passes, to provide additional source study and linguistic arguments to confirm the change in specific localizations during the time of fixing the names of the "gates" in historical writings. Caucasian etymologies have been developed for the words "Chor" and "Caspian". The use of the entire set of data, including the names of the dominant mountains with the etymologically the same word in phrases, shows the productivity of this model for constructing geographical names and determines the historical boundaries of the distribution of the languages of the North Caucasian language family.
From Papal Envoys to Martyrs of the Faith: An Attempt in Generalization of Franciscan preaching in China in the 13th– 18th Centuries
Authors: Dubrovskaya Dinara V.
Published: October 2021

The article is an attempt to systematize the preaching of the Franciscan order in China, starting with the papal embassies to the Great Khans who conquered the Middle Empire and founded the Yuan dynasty until the end of the 20th century. The author groups the information into several major periods, suggesting a five-stage periodization of the Franciscan presence in the Far East. A change in the preaching paradigm is noted during the 700 centuries of the fickle Minorites’ presence in China. While the first reconnaissance missions, achieving modest success in preaching to non-Chinese subjects of the Mongol emperors, were mainly diplomatic in nature, in modern times the mission, enjoying the support of the Spanish Padroado system, is purposefully concentrated on preaching work, especially among the poor segments of the population. Since the 16th century begins a change in the entire logistic paradigm of the Far Eastern missionary work. If in the Middle Ages the Pope had enough to send several barefoot Franciscans to the Tatars, then in modern times the church is already forced to reckon with the countries that divided the world, initiating the Age of Exploration, first of all, with Spain and Portugal, the two then superpowers, each of which supported their own preachers, competing for influence in India, China and Japan and giving the task of preaching Christianity an additional political dimension, laden with rivalry and intrigue. The article is a continuation of the piece by the same author, focusing on theoretical foundations of the Franciscan proselytization, published earlier [Dubrovskaya, 2020(1)].

Authors:   Institute of Oncology ", Miguel Pontillo Humberto ,   Dr. Miguel Pérez Carreño ”, Valencia, Venezuela, C. Rodríguez Castillo Jhorbet , Dos Santos Tolentino
Published: October 2021

!Objective: The penile cancer is a rare entity in the developed countries and its incidence increases in the developing countries, achieving up to 10% of the malignancies in men. There is a crucial association with the HPV, in the same way it relates to inadequate hygiene habits and the phimosis. The objective of the surgical treatment is resection with adequate margins, and the inguinal lymph node dissection when indicated. The restore skin coverage in these lesions is a challenge for the surgeon, as it seeks to achieve a phallus almost normal appearance, and restore the patient's tactile and the erogenous function, with the fewest possible interventions, trying to minimize the psychological trauma. Previously, many of these patients were considered inoperable and were recommended to radiation therapy to cure the injury. The evolution of the plastic surgical techniques using skin or the myocutaneous flaps, have provided the surgeon another option to keep the local oncological control with acceptable morbidity. Clinical Case: The aim of this paper is to present the case of a 56 years old male patient with diagnostic of squamous cell cancer of the penis stage II, who underwent the penile stripping, with bilateral inguinal lymphadenectomy; and rotation flap reconstruction of the scrotal skin. We found no published paper about the skin reconstruction of penile skin flap from scrotum for cancer patients, hence the importance of this work. Keywords: Cancer, Penile, HPV, Reconstruction, Faloplastia.
Correlation of Caesarean Section Rates to Maternal and Neonatal Mortality in the Eastern Mediterranean Region; A Population-Based Ecological Study
Authors:   Department of Surgery, University Hospital Centre Zagreb, Croatia, Šijak Dorotea , Bulić Krešimir , Antabak Anko , Prlić Ivica
Published: October 2021

The physiological reaction of postocclusive local reactive hyperemia is regulated by neurovascular mechanisms and it reflects the function of microcirculation. Thermoregulatory changes occur first, in the form of increased skin surface temperature, which is usually followed by an increase in local blood flow. This study investigated a correlation between tourniquet duration on the upper arm, and the appearance of reactive hyperemia in the distal parts of the upper limb. Changes were registered with infrared thermometer and infrared thermography, which provided us a highly precise view of distribution of reactive hyperemia. Changes of oxygen saturation of peripheral arterial blood and blood pressure were also recorded. Our research has shown that longer duration of tourniquet leads to more intense and longer lasting reactive hyperemia in the palmar region, followed by higher temperatures of the skin surface, without any changes in postocclusive values of SpO2. Keywords: Infrared thermography, Microcirculation, Postocclusive hyperemia, Skin temperature, Tourniquet, Thermoregulatory changes.

Published: October 2021

OBJECTIVE:

This study aimed to explore the clinical detection and prognosis of coagulation function in patients with liver failure and sepsis.

METHODS:

The plasma fibrinogen (FIB), factor II, factor VII, factor V, factor IV, antithrombin III (ATIII), platelet (PLT), mean PLT volume (MPV), D-dimer, prothrombin activity (PTA), and fibrin degradation product (FDP) levels and thromboelastogram values were detected in patients with liver failure complicated with sepsis and compared with those in the liver failure and liver cirrhosis groups. The patients with liver failure complicated with sepsis were analyzed by univariate and multivariate logistic regression, and the regression equation was established.

RESULTS:

The levels of FIB, factor II, factor VII, factor V, ATIII, PLT, MPV, D-dimer, and FDP in the patients with liver failure complicated with sepsis were compared with those in the control group patients, and the differences were statistically significant ( p < 0.05). Among the thromboelastography parameters in the patients with liver failure and sepsis, the differences in the K-value, R-value, angle, maximum amplitude, and coagulation index values compared with those of the control group were statistically significant ( p < 0.05). The logistic regression model obtained was as follows: p = 1/(1 + e [–0.128×X1–0.058×X2 + 0.211×X3 + 0.2×X4 + 0.25]). The specificity, sensitivity, and accuracy values of the regression equation in determining the prognosis were 92%, 93.9%, and 92.8%, respectively. Among the 11 factors, factor VII, PLT, FDP, and D-dimer were included in the regression equation.

CONCLUSION:

Coagulation disorder is exacerbated in patients with liver failure and sepsis. Among the 11 coagulation-related factors, factor VII, PLT, FDP, and D-dimer may be the independent factors influencing the prognosis of patients with acute liver failure and sepsis.
A systematic review on privacy-preserving distributed data mining

Published: October 2021

Combining and analysing sensitive data from multiple sources offers considerable potential for knowledge discovery. However, there are a number of issues that pose problems for such analyses, including technical barriers, privacy restrictions, security concerns, and trust issues. Privacy-preserving distributed data mining techniques (PPDDM) aim to overcome these challenges by extracting knowledge from partitioned data while minimizing the release of sensitive information. This paper reports the results and findings of a systematic review of PPDDM techniques from 231 scientific articles published in the past 20 years. We summarize the state of the art, compare the problems they address, and identify the outstanding challenges in the field. This review identifies the consequence of the lack of standard criteria to evaluate new PPDDM methods and proposes comprehensive evaluation criteria with 10 key factors. We discuss the ambiguous definitions of privacy and confusion between privacy and security in the field, and provide suggestions of how to make a clear and applicable privacy description for new PPDDM techniques. The findings from our review enhance the understanding of the challenges of applying theoretical PPDDM methods to real-life use cases, and the importance of involving legal-ethical and social experts in implementing PPDDM methods. This comprehensive review will serve as a helpful guide to past research and future opportunities in the area of PPDDM.

Background: A long-term follow-up study in patients with amnestic mild cognitive impairment (aMCI) is needed to elucidate the association between regional brain volume and psychopathological mechanisms of Alzheimer’s disease with psychosis (AD + P). Objective: The purpose of this study was to investigate the effect of the thickness of the angular cingulate cortex (ACC) on the risk of AD + P conversion in patients with aMCI. Methods: This was a hospital-based prospective longitudinal study including 174 patients with aMCI. The main outcome measure was time-to-progression from aMCI to AD + P. Subregions of the ACC (rostral ACC, rACC; caudal ACC, cACC) and hippocampus (HC) were measured as regions of interest with magnetic resonance imaging and the Freesurfer analysis at baseline. Survival analysis with time to incident AD + P as an event variable was calculated with Cox proportional hazards models using the subregions of the ACC and HC as a continuous variable. Results: Cox proportional hazard analyses showed that the risk of AD + P was associated with sub-regional ACC thickness but not HC volume: reduced cortical thickness of the left cACC (HR [95%CI], 0.224 [0.087–0.575], p = 0.002), right cACC (HR [95%CI], 0.318 [0.132–0.768], p = 0.011). This association of the cACC with the risk of AD also remained significant when adjusted for HC volume. Conclusion: We found that reduced cortical thickness of the cACC is a predictor of aMCI conversion to AD + P, independent of HC, suggesting that the ACC plays a vital role in the underlying pathogenesis of AD + P.

Published: October 2021

Fueled by aging populations and continued environmental contamination, the global burden of Parkinson’s disease (PD) is increasing. The disease, or more appropriately diseases, have multiple environmental and genetic influences but no approved disease modifying therapy. Additionally, efforts to prevent this debilitating disease have been limited. As numerous environmental contaminants (e.g., pesticides, metals, industrial chemicals) are implicated in PD, disease prevention is possible. To reduce the burden of PD, we have compiled preclinical and clinical research priorities that highlight both disease prediction and primary prevention. Though not exhaustive, the “PD prevention agenda” builds upon many years of research by our colleagues and proposes next steps through the lens of modifiable risk factors. The agenda identifies ten specific areas of further inquiry and considers the funding and policy changes that will be necessary to help prevent the world’s fastest growing brain disease.
The International Patient Summary and the Summarization Requirement
Authors: Kay Stephen
Published: October 2021

The ‘patient summary’ has an important role in delivering continuity and coordination of a person’s health and care. ‘patient summary’ implementations are pervasive and important to both healthcare providers and to their subjects of care. The digital version of the patient summary, however, often falls short of its intended functionality and its potential value. The requirements of summarization and what they mean for the communication situation in which the summarization of health and care data takes place has been analyzed. The purpose is to understand the limitations and potential of current digital solutions for communicating a ‘patient summary’. The International Patient Summary (IPS) standard is a step towards communicating safe, relevant patient summaries for use throughout the world. To meet this grand challenge, the IPS can capitalize upon the inherent capacity and competence of all people to produce and consume summaries.

Published: October 2021

According to different systematic reviews incidence of thoracic aortic aneurysms (TAA) in the general population is increasing in frequency ranging from 5 to 10.4 per 100000 patients. However, only few studies have illustrated the role of different risk factors in the onset and progression of ascending aortic dilatation. Currently, noninvasive imaging techniques are used to assess the progression rate of aortic and aortic valve disease. Transthoracic (TT) Echocardiographic examination routinely includes evaluation of the aorta It is the most available screening method for diagnosis of proximal aortic dilatation. Since the predominant area of dilation is the proximal aorta, TT-echo is often sufficient for screening. We retrospectively analyzed the ECHO database with 78499 echocardiographic records in the Almazov National Medical Research Centre to identify patients with aneurysm. Detailed information including demographic characteristics, ECHO results and comorbidities were extracted from outpatient clinic and from hospital charts related to hospitalizations occurring within a year before index echocardiography was performed. Comorbid diseases were similarly extracted from outpatient clinic and/or hospital admissions. The classifier showed an AUC-ROC for predicting of aneurism detection after a repeated ECHO at 82%.

TUBERCULOUS GLOSSITIS - A RARE EXTRAPULMONARY LOCALIZATION
Authors: Kukurika A.V.
Published: October 2021

Tuberculous glossitis is very rare, even in countries with a high tuberculosis burden. The tongue is the most frequent lesion in the structure of oral forms, the frequency of which does not exceed 0.1%. Allocate sputtogenic and hematogenous pathways of infection. The protective function of saliva, due to enzymes and antibodies in its composition, the pH of the oral cavity, the peculiarities of the blood supply, the presence of variable saprophytic microflora, a small number of lymphoid follicles, complicates the inoculation of mycobacterium tuberculosis. However, defects of the mucous membrane due to trauma, invasive interventions and chronic nonspecific inflammation in the oral cavity create favorable conditions for the vital activity of the pathogen. Analyzed 38 clinical cases of tuberculous glossitis from foreign practice, presented their brief description. The issue of timely detection and differential diagnosis of tuberculous glossitis is relevant in the practice of doctors of various profiles. Any lesion of the tongue should be carefully investigated, diagnostics should include laboratory, histological and radiation methods.

Published: October 2021

The global COVID-19 pandemic began in December 2019 and spread rapidly around the world. Worldwide, more than 230 million people fell ill, 4.75 million cases were fatal. In addition to the threat to health, the pandemic resulted in social problems, an economic crisis and the transition of an ordinary life to a "new reality". Mathematical modeling is an effective tool for controlling the epidemic process of COVID-19 in specified territories. Modeling makes it possible to predict the future dynamics of the epidemic process and to identify the factors that affect the increase in incidence in the greatest way. The simulation results enable public health professionals to take effective evidence-based responses to contain the epidemic. The study aims to develop machine learning and compartment models of COVID-19 epidemic process and to investigate experimental results of simulation. The object of research is COVID-19 epidemic process and its dynamics in territory of Ukraine. The research subjects are methods and models of epidemic process simulation, which include machine learning methods and compartment models. To achieve this aim of the research, we have used machine learning forecasting methods and have built COVID-19 epidemic process linear regression model and COVID-19 epidemic process compartment model. Because of experiments with the developed models, the predictive dynamics of the epidemic process of COVID-19 for 30 days were obtained for confirmed cases, recovered and death. For ‘Confirmed’, ‘Recovered’ and ‘Death’ cases mean errors have almost 1.15, 0.037 and 1.39 percent deviant, respectively, with a linear regression model. For ‘Confirmed’, ‘Recovered’ and ‘Death’ cases mean errors have almost 3.29, 1.08, and 0.71 percent deviant, respectively, for the SIR model. Conclusions. At this stage in the development of the epidemic process of COVID-19, it is more expedient to use a linear model to predict the incidence rate, which has shown higher accuracy and efficiency, the reason for that lies on the fact that the used linear regression model for this research was implemented on merely 30 days (from fifteen days before 2nd of March) and not the whole dataset of COVID-19. Also, it is expected that if we try to forecast in longer time ranges, the linear regression model will lose precision. Alternatively, since SIR model is more comprised in including more factors, the model is expected to perform better in fore-casting longer time ranges.

MECHANISM OF INCREASING THE COMPETITIVENESS OF AGRICULTURAL ENTERPRISES
Authors: Zheludenko Kristina
Published: October 2021

The efficiency of agricultural enterprises in the market environment depends on the level of their competitiveness. Competition encourages producers of agricultural products to implement the results of scientific and technological progress, the use of new unique technologies and products, and ensures the active development of agricultural production. Since competitiveness is one of the main indicators of the state of enterprises, its increase becomes one of the main strategic tasks of ensuring their stable development. The study of theoretical and practical issues of increasing the competitiveness of enterprises was carried out by many domestic and foreign scientists. The article presents their theoretical approaches to defining the concept of «enterprise competitiveness». Since the activities of enterprises in the agricultural sector have characteristic features associated with the specifics of agriculture, the essence of the concept of «competitiveness of agricultural enterprises» is defined. The competitiveness of enterprises in the agricultural sector depends on a number of factors that are of different nature, origin and level of impact. For effective management of the competitiveness of economic entities in the agricultural sector, a classification of their factors is proposed. Among them, natural-geographical, scientific and technical, social, organizational, financial and economic, environmental and political factors are highlighted. The article presents the scientific substantiation of the above factors and analyzes their impact on the activities of enterprises in the agricultural sector. Taking these factors into account will increase the production of high quality products, make a profit, and will help accelerate the industry's recovery from the financial crisis. The article presents a mechanism for increasing the competitiveness of agricultural enterprises and describes its stages: analysis of the competitive positions of an agricultural enterprise, the formation and implementation of the mechanism. The measures and priority directions of increasing the competitiveness of the subjects of the agrarian market are proposed.

In the author's sense, crisis management should cover all subsystems of enterprise management: operational, technical, financial, and, especially, strategic, marketing, personnel. It is recognized that marketing in crisis management is not just one of the subsystems of the enterprise, but the basis that ensures the sustainability of all its other units.
Anti-crisis marketing involves the prompt change of all components of marketing in accordance with changes in the environment, which helps to maintain maximum competitiveness of the company in market conditions. In the crisis of the organization or to prevent it, the same marketing tools are used as in stable conditions, but the goals and objectives of marketing activities change, which acquire new specific features, the main of which is the marketing anti-crisis program. The anti-crisis marketing program should ensure the production and sale of such goods that are in steady demand in the market and bring the company's main profit. The mechanism of anti-crisis marketing in the enterprise as a management system involves the presence of the object (crisis phenomena) and the subject of management, the formation of targeted management processes, subsystem monitoring environment and forecasting: determination of the stage, parameters, volumes and scales of the crisis phenomenon, development, implementation and control of anti-crisis strategies, etc.), choice of means and methods of management, creation of a clear system of adjustment and feedback.
The end result of marketing anti-crisis management of the enterprise is the formation and implementation of marketing anti-crisis strategy.

Сфера морських перевезень значно впливає на соціально-економічний розвиток і інвестиційний потенціал держав. На графіках трендів росту вантажоперевезень чітко помітний спад, пов'язаний зі світовою економічною кризою 2008-2009 року, і поточна криза у зв'язку з COVID має дуже схожі показники. Це говорить про те, що, хоча перспективи розвитку морських перевезень у цілому представляються позитивними, існує невизначеність відносно стійкості економічного пожвавлення й пов'язаних із цим наслідків для сектору морських перевезень. Така невизначеність значною мірою обумовлена комбінацією геополітичних і економічних ризиків, торговельною політикою й структурними зрушеннями, такими як перебалансування економіки Китаю, уповільнення росту глобальних виробничо-збутових ланцюжків, зміни у світовому енергетичному балансі і поточна криза. Цьому сприяє також поява нових тенденцій, зокрема поширення цифрових технологій, які можуть змінити вигляд світового судноплавства, потоки й схеми морських перевезень. Як і раніше, неясно, як ці фактори будуть розвиватися і у якому степені вони будуть підтримувати або стримувати процес пожвавлення росту морських перевезень. Очевидно, що вони потребують подальшого моніторингу й оцінки. Однак більш уважний аналіз динаміки морських перевезень по окремих видах вантажів дозволяє одержати більш чітку уяву про зміни в їхній інтенсивності. Для цього на основі статистики по вантажообігу окремих видів морських вантажів проведений регрессійно-кореляційний аналіз і отримані рівняння лінійних регресій, що описують тренди зростання вантажообігу хімічних продуктів, наливних вантажів, контейнерних перевезень і інших типів вантажів. Аналіз базується на статистиці 2000-2018 років, тому прогноз на наступні роки виконаний з припущенням збереження умов його реалізації. Події останнього часу (пандемія COVID-19 і обумовлена нею світова економічна криза) є форс-мажорними обставинами, що, природно, порушить прогноз. Прогноз у цьому випадку може бути відновлений, коли будуть відомі фактичні об'єми спаду в 2020-2021 роках.

Значна частина сучасного енергетичного обладнання працює в умовах взаємодії з оточуючим середовищем. Високі швидкості рідини спричиняють появу суттєвого тиску на поверхні конструктивних елементів. В свою чергу, коливання елементів машин та споруд в потоці рідини веде до зміни параметрів руху рідини. Тобто виникає зв’язана задача визначення міцнісних та динамічних характеристик таких систем. З одного боку коливання пружного тіла змінюють параметри течії, а з іншого саме наявність течії призводить до суттєвого впливу на динамічні характеристики конструкції. З точки зору механіки, такі задачі можна класифікувати як задачі взаємодії різних суцільних середовищ. Для опису руху суцільних середовищ використовують загальні рівняння руху, рівняння стану, закони збереження. Різні суцільні середовища відрізняються різним зв’язком між компонентами тензорів напружень та тензорів деформацій або швидкостей деформацій. За допомогою методу зважених нев’язок в роботі отримані основні співвідношення для визначення узагальнених переміщень. При цьому загальне формулювання передбачає можливість визначення частот та форм власних коливань конструкції без врахування приєднаних мас рідини, з їх урахуванням, а також досліджувати вимушені коливання елементів конструкцій з урахуванням та без урахування взаємодіє з рідиною. Для в’язкої стисливої рідини отримано формулювання задачі в акустичному наближенні. Числова реалізація здійснена в припущенні безвихрового руху ідеальної та нестисливої рідини. Для розв’язання задачі з визначення тиску рідини отримано рівняння Лапласа з умовами не протікання в якості крайових. Задачу визначення гідродинамічного тиску із застосуванням методів теорії потенціалу зведено до розв’язання гіперсингулярного інтегрального рівняння. Форми власних коливань конструктивного елементу без врахування приєднаних мас рідини обрані як базисні для розв’язання задачі визначення динамічних характеристик з урахуванням рідини. Як приклад розглянуті власні частоти та форми коливань круглої пластинки як без урахування впливу рідини, та з її урахуванням. Досліджені також гармонічні коливання цієї пластинки.

При постановке экспериментов, связанных с использованием поляризационных свойств синхротронного излучения (СИ), представляет интерес детальный расчет спектрального углового распределения СИ и его поляризационных компонент. Учет размеров пучка показывают, что в реальных условиях излучение не будет полностью поляризованным, а форма и размеры углового распределения излучения будут искажены. Рассмотрено движение электронов в однородном магнитном поле и СИ пучка релятивистских частиц в накопителе "НЕСТОР" Национального Научного Центра «Харьковский Физико- Технический Институт» (ННЦ ХФТИ). Проанализировано влияние на формирование изображений потока квантов СИ размеров пучка электронов с энергией Е=225 МэВ. Показано, что в формирование изображений основной вклад вносит двумерное распределение частиц по вертикали и по вертикальным колебаниям. Разработано программное обеспечение, использование которого дало возможность промоделировать процесс формирования оптических изображений потоком квантов СИ. Рассмотрено формирование изображений излучения электронов с энергией Е=225 МэВ при изменении продольного расстояния L до плоскости регистрации. Определено, что на малых продольных расстояниях основной вклад в изображении вносит вертикальное распределение частиц. С увеличением расстояния возрастает вклад распределения частиц по вертикальным колебаниям, который для больших L становится определяющим. Проведено численное моделирование формирования изображений. Приведено семейство угловых распределений плотности потоков σ- и π-компонент поляризации, рассчитанных для одного из каналов вывода СИ накопителя"НЕСТОР". Зависимости оформлены в виде двумерных гистограмм для длины Lmax=300 см, вертикальных среднеквадратичных параметров пучка и разных длин волн излучения, а также для разных дисперсий L σ электронного сгустка. Получены размеры оптического люка, величина которых позволяет гарантированно регистрировать весь поток квантов СИ для указанных характеристик регистрации.

Сформульована нестаціонарна задача теплопровідності для неоднорідної анізотропної оболонки, яка обмінюється теплом із навколишнім середовищем за законом Ньютона та нагрівається нестаціонарними джерелами тепла. Матеріал оболонки є неоднорідним за товщиною і анізотропним з одною площиною теплової симетрії. По аналогії з теорією пружності для оболонок просторову задачу теплопровідності зведено до математично простішої двовимірної задачі. Таке спрощення відповідає першому наближенню Лява і має місце для тонкостінних конструкцій. Записано двовимірні рівняння теплопровідності неоднорідних анізотропних оболонок для двох часто використовуваних законів розподілу температури по товщині оболонки: кубічного та лінійного розподілів. Для оболонки, складеної з пакету жорстко з’єднаних між собою однорідних анізотропних шарів різної товщини, прийнято, що гіпотеза про характер розподілу температури по товщині виконується для всього пакету. Теплофізичні характеристики шаруватої оболонки як одного цілого подано за допомогою асиметричних одиничних функцій. Для випадку такої кусково-неперервної неоднорідності отримано вирази інтегральних характеристик теплофізичних параметрів через фізичні властивості шарів. Для неоднорідної кругової замкненої ортотропної циліндричної оболонки скінченної довжини і сталої товщини з використанням подвійного скінченого перетворення Фур’є за координатами та інтегрального перетворення Лапласа за часом записано загальний розв’язок нестаціонарної задачі теплопровідності. Досліджено температурне поле шаруватої циліндричної оболонки антисиметричної регулярної структури, осі ортотропії кожного шару якої почергово орієнтовані паралельно і перпендикулярно до координатних осей. Чисельно проаналізовано розподіл температури у двошаровій графітоепоксидній композитній оболонці за локального її нагрівання у початковий момент часу заданим температурним полем або довкіллям шляхом конвективного теплообміну. Досліджено залежність інтегральних характеристик температури від фізичних та геометричних параметрів оболонки.
