Published: October 2021

Abstrak Buncis merupakan salah satu produk pertanian di Indonesia yang diekspor ke luar negeri. Setelah dipanen, buncis disimpan untuk diproses sebelum diekspor ke konsumen. Kesegaran buncis umumnya hanya bertahan selama 1 minggu, oleh karena itu diperlukan alat khusus untuk mempertahankan kesegaran buncis sebelum diekspor ke konsumen. Untuk mempertahankan kesegaran buncis, temperatur udara 4°C-7°C dengan kelembaban 90%-95% perlu dipertahankan. Dengan menggunakan cold strorage, kondisi ruang penyimpanan dapat diatur sedemikian rupa agar memenuhi kriteria tersebut. Pada penelitian ini dirancang sebuah cold storage dengan kapasitas 10 ton untuk tanaman buncis. Cooling Load Temperatur Difference (CLTD) pada perancangan ini diatur bulan dan waktunya yang disesuaikan dengan posisi dari cold storage. Beban pendinginan total untuk 10 ton buncis adalah sebesar 46,73 kW. Cold storage hasil rancangan menggunakan siklus kompresi uap dengan fluida refrigeran R134a tanpa menggunakan humidifier. Untuk mempertahankan kondisi udara pada cold storage agar sesuai dengan kebutuhan, kompressor AC dengan kapasitas 12,7 kW digunakan pada siklus kompresi uap.

Assessment of the possibility of modeling nonlinear multivariable calibration function using artificial neural networks
Authors: Molchanova E. I. , Korzhova E. N. , Fedorov V. V. , Portnyagin A. D.
Published: October 2021

The use of artificial neural networks (ANNs) is considered justified when studying the problems that do not have a generally accepted solution algorithm. One of such problems in X-ray fluorescence analysis (XRF) is a control of the metal content in atmospheric air and air of the working area. Determination of the calibration characteristics is raveled by the lack of standard samples of the composition of aerosols collected on the filter. To solve this problem, synthetic calibration samples (CS) were manufactured as a thin organic film containing a powder material of the known chemical composition. The weight of the film samples varied within a range of 40 – 155 mg to simulate different aerosol loading of the filters and the content of components in them changed 20 – 200 times which corresponds to the samples of real aerosols. The possibility of modeling a nonlinear calibration multivariable function using artificial neural networks was evaluated in analysis of 38 film calibration samples (from 40 to 100 mg). The structure of the neural network, activation functions, learning algorithms have been investigated. Modeling was performed using an academic version of the BaseGroup Deductor analytical platform. It is shown that implementation of the back propagation of errors leads to much higher values of the error of analysis compared to the error of the regression calibration functions, whereas the Resilient Propagation algorithm provides the smallest values of the error of vanadium determination (Sr) in the calibration samples of aerosols. The range of low content of the elements in the training set is determined with a greater error compared to high content range, and therefore, the sigmoid activation function leads to unsatisfactory accuracy of the analysis results, and preference should be given to hyperbolic tangent (tanh).
Study of the dependence of the strength characteristics of metals on variations in the modes of manufacturing process using microstructure-sensitive acoustic parameters
Authors: Kamyshev A. V. , Pasmanik L. A. , Radostin A. V. , Zaitsev V. Yu.
Published: October 2021

The microstructure-sensitive acoustic parameters (MSA parameters) of metal of the object under control are determined using measurements of the propagation time of bulk elastic waves of the ultrasonic range by the echo-pulse method. The structural features of the metal are thus evaluated not only in the surface layer, but also throughout the entire volume. We present the results of practical application of the MSA-parameters to estimation of the deviation of the velocity ratios of longitudinal and shear waves relative to the «basic» state with known strength characteristics. A correlation of the MSA-parameters with variations in the elastic moduli of metals attributed to modification of their microstructure is discussed. The generalized values of the ratios of wave velocities for steels of the same group are used in calculations to characterize the «base» state. It is shown that when calculating the MSA-parameters for a certain kind of construction steel, it is possible to use the averaged ratios of the velocities measured for quasi-isotropic reference samples made of the same type of steel. The generalized baseline ratios of the longitudinal and shear wave velocities are determined for the samples made of carbon steel, low-alloy, and alloyed steels. We present experimental evidence of using MSA-parameters to detect microstructural changes in metal samples and accompanying changes in their strength characteristics that occur during changes in modes and conditions of welding and heat treatment. A comparative analysis of the MSA parameters with the values of the mechanical properties and parameters of the crack resistance of the metal is carried out. It was shown that the accuracy of measuring the MCA parameters provided by modern hardware significantly exceeds changes in them occurred under significant deviations of the strength characteristics. The experimental results obtained clearly indicate that the MSA-parameters can be successfully used to improve the methods of quantitative non-destructive assessment of the features of metal microstructures

Published: October 2021

Aluminum alloys with electroplated coatings and copper plated in particular gained multiple applications. However, pre-zincate treatment often fails to provide the desired adhesion of the coating. We present the results of studying the effect of the electrolyte composition on the adhesion and other properties of the coating-base system. It is shown that an electrolyte with a reduced content of sulfuric and phosphoric acids can be used for anodizing and the oxide films formed during anodizing are stable in the usual copper-plating sulfuric acid electrolyte which eliminates contact exchange and increases adhesion. The use of a modern scratch-test method provides numerical determination of the values of adhesion of copper coatings. The adhesion value depends on the surface porosity of the oxide film and on the type of anodized alloys. The results can be used to improve the technology of applying copper coatings, both as an independent coating and as an underlayer in multilayer coatings.

Published: October 2021

Determination of the porosity, structural characteristics of pores, and gas pressure in closed pores is the most important part of assessing physical and mechanical properties of materials. The internal pressure inside the pore can be used in estimating the level of strength reliability of the porous volume of the product to optimize the technological processes of product manufacturing, control their structure and properties, and avoid the formation of cracks at the boundaries of the particles consisting the material. We present a method for calculating the internal pressure in a spherical pore that has arisen in the material of a product obtained using powder metallurgy or additive technologies. The proposed procedure for measuring internal pressure in a pore consists in application of an external pressure to the product, measurements of the displacements of the points on the pore surface, and calculation of the internal pressure from the difference between the displacements. In this case, the known solutions of the problem of the theory of elasticity regarding the deformation of a spherical cavity located in the center of a spherical hollow ball are used. The results obtained can be used to assess the properties and structure of the products obtained by additive technology and methods of powder metallurgy, as well as to improve the technology of their manufacture.
Technique for accelerated tests of samples for wear resistance
Authors: Rozhkov Yu. N. , Aulov V. F. , Ivanov V. I.
Published: October 2021

A review of the existing methods of accelerated abrasive wear tests is presented. The shortcomings of the technique implemented on an IM-01 installation of the VISKHOM design, as well as the Brinell-Howarth technique for laboratory studies, in which a powder abrasive is used are discussed, e.g., a problem of a uniform distribution of a free-flowing abrasive material over the surface of the contact zone, as well as problems of ensuring the stability of the supply of the abrasive material during the experiment. The goal of the study is to develop a methodology for comparative assessment of the wear resistance, excluding noted shortcomings. The tests were carried out on an M-1 installation using plate specimens 60 × 40 × 3 mm. The abrasive material used was a radial flap wheel 150 – 220 mm in diameter (width 30 mm, bore diameter 30 – 40 mm). The degree of wear was determined by a decrease in the mass of the sample by weighing on a balance with an accuracy of 0.1 mg before and after testing. The test results were considered as a relative wear resistance ε equal to the ratio of the wear resistance of the test specimen to the wear resistance of the reference one. The use of relative wear resistance makes it possible to increase the accuracy of the results obtained due to elimination of the influence of natural changes in external parameters that determine the intensity of wear during the test. The developed installation provides significant shortening of the accelerated comparative test (8 min) compared to 40 min on an IM-1, the structure and grain size of the working fluid, the constancy of the load in the contact zone and the speed of interaction between the sample and the tool being the same. Flap wheels of various grain sizes provide application of the device to a wide range of tasks without preliminary grinding of the samples and necessitate only their preliminary cleaning from slags and large particles after applying wear-resistant coatings.
DISCUSSION ON “AYKOL MANAS” IN THE CONTEXT OF THE HISTORICAL RELATIONSHIP BETWEEN SHAMANISM AND STORYTELLING AMONG THE KYRGYZ PEOPLE
Authors:   N. N. Miklukho-Maklai Institute of Ethnology and Anthropology, Russian Academy of Sciences, Manichkin Nestor A.
Published: October 2021

The article dwells upon connection between the two most important Kyrgyz traditions: shamanism ( bakshylyk ) and storytelling ( zhomokchuluk ). It considers the general cultural and social field that forms some features that are characteristic of both shamans and storytellers, as well as the traces of pre-Islamic culture that can be found in the world of the Kyrgyz epic. Special attention is paid to the post-folklor version of the epic “Manas” – the dastan “Aykol Manas” and the public discussion around that literary work. The discussion reflects, on the one hand, specific aspects of the understanding of the Kyrgyz epic tradition, and on the other hand, a number of characteristic features that accompany modern transformations of Kyrgyz shamanism.
THE CONTRIBUTION OF E. M. MELETINSKY TO THE CAUCASIAN EPOS STUDIES. ON THE 100TH ANNIVERSARY OF THE BIRTH OF THE SCHOLAR
Authors:   Academy of Sciences of Abkhazia, Dzhapua Zurab D.
Published: October 2021

The article analyses the contribution of Meletinsky to Caucasian epic studies. The role of Caucasian epic traditions in the study of the problem of the origins and the early forms of the epos is considered. A significant number of the comparative-typological studies of Meletinsky are based on the materials of mythoepic cultures of Caucasus mountain people. The scholar singled out the Caucasian epics, along with some other traditions, as the special early stage in the history of the epic. Meletinsky was one of the pioneers in the fundamental studies of the Caucasian Nart epics. Based on the analysis of materials available to him at that time, Meletinsky comes to the fundamental conclusions on the genre nature, national versions, images, subjects and motifs of the Nart epic. The scholar considered Sataney and Sasrykua to be the earliest characters in the epic, whose images clearly reflected the features of a cultural hero, especially in the close Abkhaz and Adyg versions. Furthermore, according to Meletinsky, the Transcaucasian legends about the chained heroes – Abkhaz Abryskil, Armenian Mger and Georgian Amiran – represent a kind of interweaving of mythological epic and heroic tales, in which the motives of cultural exploits are largely supplanted by episodes of the heroic struggle with Giants. In the studies of Meletinsky, the epic traditions of the people of the North Caucasus and Transcaucasia are subjected to the deepest analysis at a very high level of comparative studies.
THE TURKIC DELI [POSSESSED] DOMRUL AND THE GREEK ADMET. A STUDY BY W. EBERHARD
Authors:   Institute of Oriental Studies RAS, Anikeeva Tatiana A.
Published: October 2021

The article contains a commented publication of a fragment from the unpublished work of a Sinologist Wolfram Eberhard (1909–1989) “Über die Erzählungen des Dede Korkut” (“On the legends of” “Dede Korkut”). “The Book of Dede Korkut” always was the object of particular interest to scholars engaged in comparative research and typology of folklore. It is generally accepted that the formation of some of the legends, included in “Kitab-i Dedem Korkut”, was strongly influenced by both the Byzantine, Greek folklore, and archaic plots of the earlier period, what became the starting point of the research in W. Eberhard’s unpublished work. An important feature of Eberhard’s work distinguishing it from the actual Turkological studies of “ The Book of Korkut” and Turkish folklore in general, is an attempt to make comparisons with Greek myths, many monuments of the Indian and Persian literary tradition, thus placing the Oghuz epic in the broad context of the history of world literature. The published excerpt dwells with the legend of the possessed Domrul as part of the Turkish book epic “The Book of Dede Korkut”, its origin and parallels with the ancient mythology and plots of the “Ocean of Legends” by Somadeva and “Mahabharata”.

A Teoria do Fato Social desenvolvida pelo sociólogo francês Émile Durkheim apresenta regras para observação e estudo dos fenômenos sociais externos, coercitiveis e gerais, tendo como cenário a sociedade detentora de uma consciência própria (realidade sui generis), independente da consciência individual. Diante da relevância dos estudos de Durkheim, buscou-se realizar uma pesquisa de natureza descritiva para sistematizar a Teoria do Fato Social, por meio de conceitos, métodos e aplicações encontrados nas obras do próprio autor, com o objetivo de criar um modelo teórico-analítico baseado em Durkheim para analisar a corrupção nos tempos atuais. Nesse sentido, realizou-se uma pesquisa bibliográfica tendo como objeto de busca as obras do autor, bem como artigos nacionais e internacionais relacionados à teoria do fato social. A importância do presente estudo reside na possibilidade de compreender os estudos de Durkheim, possibilitando sistematizar uma perspectiva teórica para aplicação em futuros estudos sobre análise de fatos sociais ligados a administração pública como a corrupção. Conclui-se que a corrupção é um fato social inerente ao estado de anomia da sociedade. Propõe-se como futuros estudos a aplicação do modelo teórico de corrupção elaborado a partir da perspectiva durkheimiana.

Corruption as a durkheimian social fact: proposition of a theoretical model
Abstract
The Theory of Social Fact developed by the French sociologist Émile Durkheim presents rules for the observation and study of external, coercible and general social phenomena based on a society that has its own consciousness (sui generis reality), independent of individual consciousness. Given the relevance of Durkheim's studies, a descriptive nature research was sought to systematize the Social Fact Theory, through concepts, methods and applications found in the author's own works, with the aim of creating an analytical theoretical model based in Durkheim to analyze corruption in modern times. In this sense, a bibliographical research was carried out with the author's works as a search object, as well as national and international articles related to the Theory of Social Fact. The importance of this study lies in the possibility of understanding Durkheim's studies, enabling the systematization of a theoretical perspective for application in future studies on the analysis of social facts linked to public administration such as corruption. It is concluded that corruption is a social fact inherent to the state of anomie of society. It is proposed as future studies the application of the theoretical model of corruption elaborated from the Durkheimian perspective.

Abstract

 

Indonesia is a country that is prone to earthquakes. Many houses or buildings in Indonesia are built using reinforced concrete material. Shear damage to reinforced concrete elements is very dangerous, because this damage occurs suddenly and usually occurs explosively. The nonlinear three-dimensional finite element analysis of self-compacting concrete beam and high strength concrete beam by mechanical compaction were carried out using the MSC Marc/Mentat software. Steel is modeled by being embedded in concrete. The Mohr-Coulomb Linear failure criterion is used for concrete and Von Mises for reinforcing steel. The results of the load- deflection curves for both self-compacting and mechanical compaction high-strength concrete beams are almost the same as those of the experimental curves in the elastic area, after elasticity, the analysis curve differs slightly from the experimental curve. The results of the theoretical analysis of the strength of the concrete are almost the same as the results of the analysis of the finite element concrete beams without reinforcement. The results of the contact analysis also showed that there was contact and detachment in the contact area of the load bearing steel and the beam support with the concrete.

São raros os criadores de uma ruptura epistemológica, quer dizer, de uma nova leitura possível da realidade. No campo da filosofia ocidental moderna criadores assim foram Descartes, Kant, Hegel, Marx, Heidegger e outros. Na teologia foram Tomás de Aquino, Lutero, Bultmann, Rahner e outros. Gustavo Gutiérrez abriu um caminho novo e promissor para o pensamento teológico, excogitou uma maneira nova de fazer teologia. É a pretensão da teologia da libertação como corrente dentro do cristianismo: de ser uma nova maneira de pensar Deus e todas as coisas ligadas a Deus. A libertação não significa apenas um tema na agenda dos teólogos. É um horizonte a partir do qual todas as coisas são iluminadas, é um campo no qual tudo se situa e ganha nova significação. Não se trata, pois, de libertação como um verbete dentro de uma enciclopédia, ao lado de outros verbetes. Trata-se de uma ótica pela qual se entendem, analisam e se expõem todos os demais verbetes...
Gustavo Gutiérrez – um Perfil Amigo
Authors: Betto Frei
Published: October 2021

Multiplicam-se livros, teses, artigos e resenhas sobre as obras de teólogos como Gustavo Gutiérrez, Leonardo Boff, Hugo Assmann, Juan Luis Segundo, José Míguez Bonino, Elsa Támez e de tantos outros identificados com os critérios e a metodologia da Teologia da Libertação. Esta ocupa o lugar de prima-donna na Teologia contemporânea. Graças às Instruções do cardeal Ratzinger, a TdL (Teologia da Libertação) tornou-se tema de interesse até mesmo da Academia de Ciências da União Soviética, como nos foi possível constatar na viagem de um grupo de teólogos àquele país em junho de 1987. As duas Instruções emitidas pela Congregação da Doutrina da Fé e o processo contra o livro Igreja: Carisma e Poder e a pessoa de seu autor, Leonardo Boff, fizeram o debate teológico transcender os veneráveis muros das instituições eclesiásticas e ocupar amplos espaços nos meios de comunicação, nas universidades e nos movimentos políticos...
A Negação do Sujeito na empresa colonial
Authors: Castelo Branco Manoel J. de F.
Published: October 2021

O conceito de pobre é um abstrato universalizado na filosofia, nas ciências sociais e na pastoral de base. É um conceito que se tornou um lugar comum tanto na teoria social quanto no discurso político, mas que nunca se objetiva na prática social concreta, a não ser nos casos raros de alguma pastoral de hoje. O que mostra a riqueza do conceito e ao mesmo tempo o vazio em que se perde sempre, porque nunca diz nada...
Surgical treatment of urethral tuberculosis in men – history and present (literature review)

The literature review provides data on tuberculosis of the urethra in men. This disease is rarely recorded, as a rule, at the stage of formation of the urethral stricture, which can develop many years after the onset of the disease. Urethral tuberculosis is usually secondary to other localizations of extrapulmonary tuberculosis, such as tuberculosis of the prostate, penis, kidney, and bladder, but there are also isolated forms of this disease. The most common symptoms of urethral tuberculosis are the presence of strictures, skin-urethral and recto-prostatic fistulas, and purulent urethritis. Almost always, with this disease, conservative specific therapy was carried out, which in some cases made it possible to completely eliminate the symptoms and ensure the patient’s clinical recovery. Tuberculous urethral strictures are operated on according to generally accepted rules, but there is no single algorithm for the surgical treatment of strictures of this etiology, often limiting itself only to urine diversion or urethral dilation. Of the urethroplasty, the most commonly used end-to-end urethral anastomosis. In our opinion, a promising direction is the use of various grafts for the surgical treatment of this disease.

Cardiovascular disease has serious economic and social consequences that affect people, health systems and societies around the world. Ischemic heart disease is one of the main global causes of death of the population, and its growth is predicted in the coming years. This fact continues to be of serious concern to health, social and economic services. Cardiovascular disease remains the most common cause of death, and age-standardized rates are higher for men than for women. Cardiovascular comorbidity increases significantly with age.The combination of ischemic heart disease and comorbid pathology is noted in cancer incidence, bronchial asthma, non-alcoholic fatty liver disease, type 2 diabetes mellitus, chronic obstructive pulmonary disease, periodontal disease, etc. It is necessary to analyze the existing disease with past diseases, risk factors and predictors available in the patient. The presence of concomitant diseases quite often requires additional diagnostic methods and changes in the tactics of treating coronary heart disease due to the fact that some of them are a contraindication to the use of certain groups of drugs. Periodontal disease includes a wide range of inflammatory conditions that affect the supporting structures of the teeth, which can lead to tooth loss and contribute to systemic inflammation. Periodontal disease is associated with several systemic diseases, one of which is coronary artery disease. It is imperative that clinicians understand the link between periodontal disease and cardiovascular disease. Comprehensive treatment of periodontitis and restoration of a healthy periodontium can help reduce overall inflammation in the body and reduce the risks of coronary heart disease.
Importance of extremophilic microorganisms in biogeochemical cycles
Authors: Arlette Galván González  , Rocío Pérez y Terrón
Published: October 2021

Extremophilic microorganisms are organisms capable of proliferating under extreme conditions that are generally detrimental to most life on Earth. They are organisms considered of importance in different areas of research, due to their ability to produce proteins and enzymes under inhospitable conditions. Therefore, in the present work, the information on their participation in the processes of biogeochemical cycles was collected and analyzed in order to demonstrate their ecological importance. Recent studies on the metabolic pathways of the Extremophilic microorganisms and their environment have shown that most of the archaea, some bacteria and cyanobacteria carry out metabolic activities essential for the biogeochemical cycles of sulfur, carbon and nitrogen. Archaea and bacteria being one of the main microorganisms that participate in a variety of processes such as sulfidogenesis, methanogenesis, ANAMMOX (anaerobic ammonium oxidation), among others. This has suggested that Extremophilic microorganisms and extreme ecosystems have a significant impact on global biogeochemical cycles.
The Localisation of Kumano Gongen Cult and Mountain Beliefs: From engi to kagura
Authors: Suzuki Masataka
Published: October 2021

This paper discusses the Kumano Gongen cult, which played an important role for Japanese religious beliefs and mountain beliefs. The first part is the analysis of the engi of Kumano in comparison with that of Hikosan in medieval times. The second part focuses on the localisation of Kumano Gongen cult tracing and explaining the shift from engi to kagura in medieval and modern times. This paper analyses the contents of the Kumano Gongen gosuijaku engi focusing on three themes: 1) mountain beliefs found in engi narratives; 2) the concept of kami; and 3) the diffusion and localisation of religious concepts about Kirime no Ōji, showing how the shift from Gongen to Ōji occurred.
The Multilocality of Satoyama
Landscape, Cultural Heritage and Environmental Sustainability in Japan
Authors: Bulian Giovanni
Published: October 2021

Using the versatile concept of multilocality, the paper analyses the close interrelation between Japanese landscape, cultural heritage and social construction of spatial meaning in the context of satoyama (mountain village). Originally intended as a peripheral space of subsistence within the rural economy, satoyama is considered today one of the main expressions of the Japanese local culture guided by identity mechanisms and based on complex discursive constructions of native place-based and environmental rhetoric. At the same time, the satoyama landscape has also become a transnational symbol promoted by the Japanese government which is used in national and international research programmes for environmental sustainability. The sense of multilocality of the satoyama landscape is here interpreted in its double identity value that can be put to a wide variety of political and cultural constructions of place.
Researching Shamanism in Contemporary Japan
Authors: Rivadossi Silvia
Published: October 2021

This paper takes its cue from Massimo Raveri’s studies and interests, especially concerning Japanese shamanic practitioners and the relationship between media and religion. By further broadening his analysis with more recent data, this paper suggests how a study of contemporary Japanese shamanism could be undertaken, within the theoretical framework offered by critical discourse analysis. Through the suggested examination of the multiple discourses on shamans conducted in peripheral and central areas of the country, it would be possible to reach a better understanding of both shamanism and contemporary society, overcoming essentialist views.

The Android and the Fax: Robots, AI and Buddhism in Japan
Authors: Baffelli Erica
Published: October 2021

In March 2019, a temple in Kyoto, Kōdaiji, unveiled to the public ‘Mindar’, a robot developed in collaboration with Ishiguro Hiroshi, a well-known robotics professor at Osaka University. The android is presented as the manifestation of Kannon, the bodhisattva of compassion. It can move, speak, and record what it sees. Mindar delivers sermons based on the Heart Sutra and, according to the temple’s priest, it will keep evolving and its knowledge will become endless. Mindar has received mixed responses from visitors, from those who cry during the sermons to those who feel it inappropriate for a robot to preach in a temple. Media coverage has mainly focused on the potential for Mindar to change the image of Buddhism in Japan, a tradition often portrayed as antiquated and mainly focused on funerary rituals. By examining the declarations of Mindar’s creators and varied responses of its visitors, and drawing on observation of Mindar’s practice, this chapter explores the interaction between AI, robotics, and Buddhism in contemporary Japan. It highlights the affective potentialities and possibilities of AI, in particular as they relate to emotional connections between humans and robots, and the implications for Buddhism in contemporary Japan.
