The Role of the Monasteries of Vologda and Beloozero Regions in the Development of the Social-Cultural Life of This Region in the 15th-16th Centuries
Authors: Мерзляков Иоанн
Published: April 2022

Статья освещает некоторые направления деятельности самых известных и значимых монастырей Вологодско-Белозерского края в XV-XVI вв.: Успенского Кирилло-Белозерского, Покровского Дионисиево-Глушицкого, Введенского Корнилиево-Комельского. История этих монастырей показывает, что уже в первые десятилетия своего существования, часто по инициативе подвижников-основателей и их самых активных продолжателей, выстраивались такие направления их деятельности, которые со временем стали неотъемлемой составляющей русской монастырской жизни: благотворительность, просвещение, отчасти формирование взглядов на искусство - зодчество, иконопись, книжное дело, прикладные направления. Именно деятельность монастырей в этих сферах более полно отражает особенности и тенденции развития этих направлений в целом в обществе средневековой Руси.

This article reports about the activity of the most famous and important monasteries in the Vologda and Beloozero Region in the 15-16 centuries: The Kirillo-Belozersky Monastery (or the Dormition Monastery of St. Cyril), The Dionysius Glushitsky’s Monastery to the Protection of The Virgin Mary, the Saint Cornelius’ Monastery to the Entrance of the Theotokos into the Temple. The history of these monasteries shows that, since the first decades of the monasteries’ existence their founders and their disciples participated in the activities that became integral part of monastery life in Russia in the following centuries, such as charity, education, development of the outlook at the art, icon painting, books, applied art. It is the monasteries activity in previously mentioned spheres that most totally reflects the process of development in the mediaeval Russian society.

Епископ Краснодарский и Кубанский Памфил (Лясковский) ушёл из жизни весьма неординарным для высшего духовенства образом. 10 января 1936 г. он был найден повешенным на дереве в саду дома, в котором жил последнее время; в кармане оказалась записка: «В моей смерти прошу никого не винить…» При этом могила владыки в народе всегда имела почитание. Над ней построена часовня, где хранятся две толстые тетради, в которые записаны свидетельства о чудесной помощи Божией по молитвам епископу Памфилу. Почитатели архипастыря убеждены в том, что его самоубийство на самом деле было инсценировкой, устроенной сотрудниками НКВД. В данной статье представлен анализ документальных сведений о пребывании епископа Памфила на викарной Стародубской кафедре (1922 - начало 1923 г.), в контексте церковной истории Гомельской губернии того времени; рассматриваются церковно-государственные отношения и внутрицерковная жизнь в Гомельской губернии, в условиях изъятия церковных ценностей и развивающегося обновленческого движения. На примере будущего идейного борца с обновленчеством епископа Памфила (Лясковского) показаны сложности положения русского епископата в советском государстве в начале 1920-х гг., в период антирелигиозных гонений и всемерно поддерживавшегося безбожной властью церковного раскола. Уточнён целый ряд эпизодов из биографии архипастыря; многие из цитируемых документов публикуются впервые.

Pamphil (Lyaskovsky), Bishop of Krasnodar and Kuban, passed away in a very unusual way for the higher clergy. On January 10, 1936, he was found hanged from a tree in the garden of the house where he had lived recently; there was a note in his pocket: «I ask you not to blame anyone for my death…». The grave of the Vladyka has always had a popular veneration, which has increased many times over the past 30 years. A chapel was built above it, where two thick notebooks are kept, which contain testimonies of God’s miraculous help through prayers to Bishop Pamphilus. The archpastor’s venerators are convinced that his «suicide» was in fact a staging by the NKVD officers. This article presents documentary information about the stay of Bishop Pamphilus at the vicar Starodub cathedra (1922 - early 1923), in the context of the church history of the Gomel province of that time, church-state relations and internal church life in the Gomel province, in the context of the ongoing removal of jewelry from temples and the development of the Renovationist movement. On the example of the future ideological fighter against Renovationism, Bishop Pamphil (Lyaskovsky) (1883-1936), the author shows the difficulties of the position of the Russian episcopate in the Soviet state in the early 1920s, during the period of antireligious persecution and the church schism supported by the atheist authorities in every possible way.
CONTEMPORARIES OF THE CIVIL WAR IN RUSSIA AND REPRESENTATIVES OF ALBION: THE NATURE OF RELATIONS, REFLECTED IN THE FILM AND PHOTO DOCUMENTS OF THE BRITISH INTERVENTIONISTS IN THE PERIOD 1918–1919

Published: April 2022

Despite the British support of the Russian White movement during such events as the intervention and the Civil War in Russia, the effective actions of Albion towards the anti-Bolshevik forces can hardly be considered friendly. For centuries, Great Britain acted as an opponent of Russia, and only in the first half of the 20th century because of Kaiser and later fascist Germany threats Great Britain and Russia established short-term allied relations. The study of assessments connected with Great Britain standpoint of certain historical events in our country, as well as the historical experience of relations with this long-standing opponent of Russia made this article topical. In the article the author attempts to convey the nature of the difficult relationship between the contemporaries of the Russian Civil War and the British interventionists, based on visual history and such sources as film and photo documents of the British Expeditionary Forces in the period of 1918–1919. In order to understand the contradictory nature of relations with the British, Russian Republic (earlier the Russian Empire) previous allies, the author aims at showing the prerequisites for the invasion of the Entente countries and changes in the strategy of British political forces in relation to Russia. The study was carried out within the framework of such an interdisciplinary branch of science as «military anthropology», where the object of study is «a man in war». The article presents not only an overview of British film and photo documents, but also their attribution made with the definition of copyright holders, places and time of filming, accompanied with identifying the authors of the film and photo documents involved in creating a visual image of the Civil War in Russia. The study is based on the historical-comparative method, which made it possible to determine the differences between Russian-British relations during the Civil War in all territories of the presence of British interventionists — in the North, South and East of Russia.

METAMORPHIC TESTING-AS-A-SERVICE: A NEW DESIGN PATTERN OF CLOUD SERVERLESS SYSTEMS FOR METAMORPHIC TESTING
Authors: YUSYN Yakiv , ZABOLOTNIA Tetiana ,   National Technical University of Ukraine “Igor Sikorsky Kyiv Polytechnic Institute”
Published: April 2022

The task of quality assurance of software systems in IT is still an urgent problem, and due to the growing complexity of these systems is becoming increasingly difficult to use old methods of automated testing. One of the new methods of automated testing is metamorphic testing, which can be applied to systems of any complexity and which can be performed efficiently in the cloud. However, software for performing metamorphic tests in the cloud is still in the early stages of its development, due to the still low popularity of the method in the industry. So, the purpose of this work is to improve the software to perform metamorphic tests in the cloud by developing the corresponding design pattern to improve the expected results against the software code quality metrics. To achieve this objective, the new MTaaS design pattern has been developed that is based on the idea of metamorphic relation decomposition into individual parts together with automatic code generation of the relations’ and functions’ bodies. The combination of these two ideas allows the developer to concentrate only on the implementation of the logic of metamorphic relations, hiding from him all other details (such as creating serverless functions). To evaluate the developed design pattern, two software systems for metamorphic testing of the same software artifact were developed: one software system was implemented without the use of the MTaaS pattern, the other with its use. The following four code quality metrics were used in this evaluation: maintainability index, cyclomatic complexity, class coupling, lines of code. The analysis of evaluation results has demonstrated improvement of the class coupling and maintainability index metrics without worsening other metrics. Thus, the evaluation showed the effectiveness of using the developed design pattern during developing software systems for metamorphic testing based on serverless computing.

Published: April 2022

The productivity and accuracy machine parts often depend on the dynamic processes during machine and cutting operation. The increase requirements for machining operation and quality machine parts leads to the need to evaluate and take into account all the capabilities of the technological processing system (TS) to ensure the stability of the cutting process and increase speed. One of the features emergence and existence of self-oscillating processes, the least studied and dangerous in terms of the effect on sustainability ТS is the nonlinearity parameters elastic system of the machine tool and the processes occurring during cutting operation. Therefore, to assess the conditions for implementation of the cutting process with a steady limited amplitude of oscillations, it is necessary to analyze and take into account the main nonlinearities dynamics of the TS. The article considers dynamic processes in high-speed processing systems on the example of high-precision spindle assemblies, with analysis and following review of their different types nonlinearity. The machine tool spindle unit for the case of high-speed processing according to the working conditions approaches the scheme of the rotor system which self-oscillations can be caused by the action of non-conservative circulation-type forces that are not associated with external periodic loads or any resonant relationships: internal friction forces, hydrodynamic forces in sliding bearings and seals, electrodynamic and electromagnetic forces in the electrical components of motor-spindles. It is shown that if the nonlinearity is associated only with internal external friction and coefficients of friction forces do not depend on frequency, the amplitude and frequency of self-oscillations (unlike linear system) will depend only on relationship of friction forces.

Fillers or reinforcing components are an integral part of composite materials. A classification of composites according to structural features and fineness has been adopted. Ideas about the effect of fillers on the physical, mechanical and operational characteristics of composite materials and products have been defined and are constantly being deepened. In this regard, the use of volcanic rocks as fillers is noteworthy. The prospects for the use of certain types of volcanic rocks as disperse fillers of polymer composites are justified by their significant distribution and accumulation of fine fractions of screenings as waste during their extraction and processing. At the same time, the achievement of the effectiveness of such raw materials requires a deepening of ideas about the composition and physico-chemical properties, in the direction of which this work has been done. Physical and chemical studies in terms of evaluating the suitability of volcanic rocks (perlite, zeolite, andesite) as ingredients of polymer composite materials made it possible to obtain quantitative data on their chemical and mineralogical composition, hydrophilic-lyophilic balance and energy state of their surface. The interpretation of the obtained results concerning the potential interaction of the studied materials with polymeric binders is given taking into account the above features of their composition, structure and quantitative IR spectroscopy data in terms of structure-forming bonds Si–O–Si, S –O–Al, hydroxyl groups and adsorbed water. These features indicate the possibility of choosing volcanic rocks as fillers for polymer composites with the required lyophilic-lyophobic balance and energy state of their surface and providing an unlimited level of interaction with polymer binders as a factor in shaping the structure and properties of composites.

The structure of the device for diagnostics of technical condition of power transmission lines is considered in the work and its functional scheme is offered. The article describes the principle of operation of the diagnostic device according to the functional diagram. The scheme of power lines with three branches and timestamps from known places with inhomogeneities in the sounding of the main diagnostic device and the scheme of power lines with three branches and timestamps from known places that have inhomogeneities in the sounding of auxiliary sounding are considered. The proposed device for diagnosing the technical condition of power distribution networks is based on the method of processing a radar signal with frequency modulation of a continuous wave. Unlike existing devices, this device allows you to detect faults in certain areas of branched transmission lines; has low output power. The use of a software-tuned radio station in the development and production of a diagnostic device significantly reduces material costs. it is necessary to diagnose high-voltage power lines with a large number of branches, as well as to study areas of inhomogeneity with small amplitudes of reflected signals. This paper substantiates the structure and principle of operation of the location sensing device for assessing the technical condition of electrical distribution networks in ice. The novelty is the use of special broadband signals for sounding and their optimal processing, in determining the location of damage (heterogeneity) in the branched overhead power lines, which are the basis of the diagnostic device of the transmission line. The diagnostic device can become a basis for the creation of the modern all-Ukrainian dispatching point of the analysis of a technical condition and management of the equipment of electric networks by power supply lines.

Widespread and indispensable growth of natural adsorbents use is caused by the fact that they, having developed specific surface and good (often specific) bleaching peculiarities, are dozens of times cheaper than artificial adsorbents. It leads to simplification of its usage technology – they often exclude the regeneration stage from the scheme. Chemical and thermal stability of saponite, as well as ion exchange properties, open opportunities for the creation of porous materials based on natural minerals with controlled properties that can replace synthetic analogues, the production of which is associated with high technological costs. The increase in the use of natural adsorbents is based on its specific surface area and good bleaching properties which are ten times cheaper than artificial adsorbents. In this regard, the technology of their application is simplified: the regeneration stage is often excluded from the scheme. Chemical and thermal stability of saponites, as well as ion exchange properties, open up new avenues for the creation of porous materials based on natural minerals with controlled properties that can replace synthetic analogues, the production of which is associated with high technological costs. The expediency of purification of hydrocarbon mixtures using granular saponite to obtain high-octane fuels has been studied. The influence of fuel distillation temperature on its main physicochemical parameters has been studied. The fractional composition of fuel, which is affected by such indicators as: engine warm-up speed, wear of the cylinder-piston group have been investigated. The obtained results of investigations of structural, physic and chemical properties of natural minerals allow to develop theoretical and practical bases of target change of the complex of specific properties that satisfy the basic requirements, which are put forward for sorption materials. The chemical and thermal stability of glauconites, as well as ion-exchange properties, provide opportunities for the production of porous materials based on natural minerals with controlled properties that can replace synthetic analogues associated with high technological costs.

It is important today to increase the shelf life of fats used for the production of culinary and confectionery products in the food industry and in the restaurant industry. Fats are part of a variety of dishes and products in various quantities (from 1 % in fresh salads to almost 85 % in creams). When stored under the influence of light, air and moisture in fats, chemical reactions occur, mainly oxidative, which significantly impair their organoleptic and physicochemical parameters. In existing recipes, most dishes use mainly vegetable oil, margarine, cooking fat, and for children’s and special dietary foods – butter. Therefore, it was important to investigate the use of powders from different fractions of grape pomace and pomace extract as antioxidants for some fats with a very limited shelf life, including butter and margarine, which are often used to produce a variety of culinary products and confectionery. The article is devoted to topical issues of using powders from different fractions of grape pomace and their extract as antioxidants for food fats. A previous analysis of the chemical composition of powders from grape pomace showed that they retain as much as possible in native form all biologically active substances and vitamin complexes, including those responsible for antioxidant activity. It is established that to slow down the oxidation of fats and increase their shelf life, it is rational to pre-introduce into these fats powders of grape pomace in the amount of 5 % by weight of fat and extract from grape pomace in the amount of 0,5 % (dry matter) by weight fat. Such concentrations of additives do not impair the organoleptic and physicochemical parameters of the quality of the original product and can extend the shelf life, in particular, butter by 30-80 %. Such an increase in the shelf life of butter in production will contribute to a slower accumulation of free acids and peroxides during the established shelf life.

Increasing grain production and the preparation of the required amount of seed place new demands on the machinery and technology used for post-harvest treatment and, in particular, the drying of crops. As classical thermal methods of grain drying are very energy-intensive, the possibility of their effective application is limited by the properties of the dried material. The dryers used are physically and morally obsolete and do not meet modern energy saving requirements. Therefore, it is necessary to carry out intensive steps to develop and implement in the production of modern high-performance methods of grain drying and drying equipment designs. Promising ways to improve the quality of grain material and reduce energy consumption in the technological operation of drying is the use of vibration, ensuring uniform processing of grain material by constantly updating the surface of the grain in contact with the drying agent and the introduction of ozone drying. To implement high-quality drying of grain raw materials, an experimental model of a vibro-ozone complex was designed and manufactured, in which the processed material is subjected to vibration, which increases and renews the heat transfer surface. As a result, there is an intensive removal of moisture, increasing the drying rate. The drying process is moderate throughout the layer, without causing local overheating of the material. When drying grain raw materials in the vibro-ozone complex, in order to optimize the implementation of this technological process, it is necessary to establish one of the important parameters, namely the dose of treatment with ozone-air mixture. The method of determining the dose of processing of grain raw materials during drying with ozone-air mixture using the developed vibro-ozone complex, providing high-quality implementation of the technological process while reducing energy consumption.

The article considers an improved method of comprehensive assessment of the impact of washing at home on the physical and mechanical properties of textile materials intended for the manufacture of children’s casual wear. In developing the methodological basis for assessing the change in the properties of fabrics from washing, we used the results of our own observations, which allowed us to analyze the operating conditions of preschool children’s clothing, activities and characteristic movements of children on playgrounds, identify key factors of destruction of products. features, topography of wear, frequency of cleaning from dirt, method of drying, etc. Thus, it can be argued that the shrinkage of fibrous systems depends on a sufficient number of factors that can affect simultaneously and comprehensively, and therefore this process should be classified as multifactorial and difficult to study, as the evaluation method used today is insufficient informative. The maximum allowable norms of such indicators as breaking characteristics up to (-15%) have been established; air permeability coefficient up to (-15%); abrasion resistance on the plane up to (-30%); thickness up to (+20%). The recommended method has been tested experimentally. Evaluation of changes in physical and mechanical characteristics of samples from the impact of repeated processing in the washing bath of a new recipe, close to home, was performed after each wash cycle using informative indicators such as breaking force based on Po, (N) air permeability coefficients Kp (dm3/m2·s) resistance of samples to abrasion in the plane Cs (cycles) and its thickness L (mm). The obtained results show the dependence of all indicators without exception on the number of washing cycles in soap and soda solution, with such as bursting loads of samples, their resistance to abrasion on the plane and air permeability decreases, and thickness increases compared to initial characteristics. The textile material should be considered resistant to the number of washing cycles in the soap and soda solution, which led to a change in at least one of the four criteria to the specified maximum allowable values.

The main reason holding back the wide distribution of pumpkin, like some other crops, is the lack of quality seeds. The receipt and storage of seed is largely dependent on the methods and means of drying. When choosing a technology and means for drying pumpkin seeds, one must take into account their adhesion properties, that is, the tendency to form conglomerates under certain conditions, sticking to working bodies, etc. Drying equipment should ensure uniform drying throughout the entire volume of products with different moisture content, as well as a change in the main process parameters – temperature and drying agent feed rate, which will allow the use of differential drying modes. But in drying installations used for grain processing, it is practically impossible to organize a high-quality process due to the impossibility of using differentiated modes of drying seeds, as well as increased cohesive-adhesive properties of the pumpkin seed layer. A much greater effect is achieved by devices with active hydrodynamic modes, in particular, in a fluidized bed with its modifications: an aerial boiling, vibroboiling and aerovibroboiling bed. In order to improve the flowability of a layer of materials prone to sticking, sticking, the formation of channels in the material layer, agglomeration, at the initial stage of drying, along with vibration and aeration mixing, it is advisable to use additional mechanical mixing devices. The article proposes a fundamentally new concept of energy-saving drying of high-moisture seed materials, in particular pumpkin seeds, the drying process of which through specific morphological, thermophysical, increased cohesive-adhesive properties, the presence of residues of the surface film and fruit in the seed layer is the most energy-intensive. At the first stage in the process of filtration drying, in which the heated drying agent under the influence of pressure drops moves through the cellular structure of the gas-permeable material, the drying of the material also occurs due to a change in the state of aggregation of the available, mainly surface, moisture. At the second stage, when the seeds acquire discrete properties, drying occurs in the aerovibroboiling layer due to the developed phase contact and an increase in the convective diffusion rate, which contributes to an increase in the drying rate in general and allows the process to be carried out at the maximum permissible values of seed heating. To carry out research to determine the rational technological parameters of the process, a structural and technological scheme of a vibration unit has been developed and a prototype has been created, which sequentially implements the filtration and convective stages of drying pumpkin seeds.

In recent years, there has been a noticeable trend in the research and development of mobile applications for working with consumers’ wardrobes. Several applications have similar functions. The applications can be found on the platforms of Google Play, App Store, and others. However, all these works are aimed primarily at meeting the needs of end-users of garment products. Thus, the main goal of the current research is to provide a reasonable selection method to choose a mobile application for the specific situation. The performed comparative analysis of mobile applications for creating a capsule wardrobe allows one to reasonably choose a mobile application for use in the learning process, as well as in the domain of the real economy besides operating by end-users themselves. In this case, in a specific project or a specific educational situation, it is advisable to form a list of additional requirements that are key to solving this problem. The formulated working hypothesis of the research on the possibility of adapting existing mobile applications to the production/training needs of the apparel industry has been confirmed by the example of several applications. The use of ready-made mobile applications that already exist in the market of mobile technologies, allows companies to offer technology that does not require any costs for its implementation; it does not require any additional equipment – almost every employee already has a smartphone. In addition, such technology does not require additional training. The same thesis applies to education: no additional equipment is needed to attract such technology. Higher education students can take advantage of automation even in classrooms that are not equipped with computers. The implementation of digital tools such as mobile applications in the educational process will increase the interest and involvement of students in the learning process. Customizing mobile applications that are already on the mobile market will create a transition between the learning process and specific project situations in the workplace. It will provide the young specialist with a digital tool that avoids mechanical errors and facilitates the decision-making process.

The paper shows the promising feasibility of using the clitoral ternary Clitoria ternatea L. in the food industry. The main color molecules of C. ternatea flowers are various anthocyanins derived from the main classes of dolphinidin, such as ternatine. The blue color of flowers contains anthocyanins, which are widely used as a natural source of food dyes. The main properties of anthocyanins - adaptogenic, antispasmodic, anti-inflammatory and stimulating functions; antiallergic action; bactericidal, choleretic, sedative, hemostatic, antiviral properties; insulin-like, photosensitizing action; reduction of fragility and permeability of capillaries, increase of elasticity of vessels; lowering blood cholesterol; increase visual acuity, normalize intraocular pressure; strengthening the body's immunity and protective functions. Anthocyanin dyes of phenolic nature, which belong to bioflavonoids, occupy a special place among biologically active substances in plant raw materials of the clitoral triad. They determine the color of flowers from blue to blue. These plant pigments - anthocyanins - are well soluble in water. The most important factors on which the stability of anthocyanins depends are enzymes, temperature, oxygen, pH, heavy metal ions, ascorbic acid, light, etc. The intensity and variety of color in food depends on the acid content and pH. The same anthocyanins in an acidic environment give a red color, when the pH is shifted to the alkaline side give a blue or purple color, and in a strongly alkaline environment - green. Anthocyanins of flowers сlitoria ternatea L. can be used as a blue food coloring in acidic and neutral foods, in order to restore and increase the intensity of natural color, coloring colorless products and give them an attractive and marketable appearance.

Recently, the intuitive-oriented program for designers and architects, which is used to quickly create three-dimensional models of objects, structures, buildings and interiors – SketchUp, has gained widespread recognition in the world of 3D. So now almost all other developers include in their software products or direct support for models (files) SketchUp, or data exchange with it through special plug-ins. SketchUp is designed primarily for sketch, searchable 3D modeling in three-dimensional space. However, SketchUp is successfully used to develop a variety of projects in all genres of design, advertising, engineering design, film and game production. The saltation in the increasing popularity of SketchUp has occurred since the program was “tied” to the new owner’s Internet projects – Google 3D models and Google Earth. The reason for choosing and acquiring SketchUp by Google, apparently, was its simplicity and accessibility. By creating a model of an architectural structure or any other object in SketchUp, users could place their creations in the public online collections of Google. So, in particular, the selection of collections “Cities under development” contains several thousand models of real architectural buildings of the world. At the same time, Google accepted 3D models only with the requirement that they were textured and equipped with the correct geographical reference. Compared to many other popular packages, SketchUp has a number of features that are positioned as advantages. The main feature of this program is the almost complete absence of pre-configuration windows. All geometric characteristics during or immediately after the end of the tool are set from the keyboard in the Value Control Box. Another key feature is the Push/Pull tool, which allows any plane to be “pulled out” to the side, creating new side walls as it moves. You can move the plane against the predetermined curve, using a special tool Follow Me. The program is also characterized by extreme accuracy of calculations and measurements.
