In this paper the burn-out of the alloying elements Ti, Al in the electroslag refining was studied. The experiment was conducted on laboratory scale electroslag refining (ERS) equipment, the steel grades used in the study contain Ti and Al alloy elements. Experimental results showed that the burn-out ratio of Ti and Al in ESR was quite high. To minimize that ratio, it was possible to apply technological measures such as: using protective gas and selecting of an appropriate slag system, as well as combining additives containing Ti and Al for slag in the refining process. When applying these measures, the burning level of Ti and Al has decreased significantly compared to the previous one (from > 50 % to below 20 %). Especially in case of using the ANF-32 slag + 10 % TiO2 and conducting the operation of ESR under the Ar gas environment, the burn-out ratio of these alloy elements exhibited a negative value.

Authors:   Viện Khoa học và Kỹ thuật vật liệu, Trường Đại học Bách khoa Hà Nội – Số 1, Đại Cồ Việt, Hà Nội, Nguyen Ngoc Minh
Published: November 2021

High Cr white cast iron is an alloy widely used in the field of manufacturing parts working in conditions of high wear resistance. However, the machining process for this alloy is often difficult due to its high hardness. Therefore, the objective of this study is to find out the appropriate parameters of heat treatment process to be able for softening of high Cr white cast iron with a lower hardness, ensuring the cutting process. In this study, the samples were austenitized partially and soft annealed in a resistance furnace. Optical microscope, X-ray diffractometer and field emission scanning electron microscope were used to observe and evaluate the microstructure of samples before and after heat treatment. The Rockwell hardness tester (RHT) is also used to evaluate hardness variation of samples. Research results have shown that the change of primary carbide grain size and formation of secondary carbides during heat treatment can reduce the hardness of white cast iron to the suitable range for machining.

Published: November 2021

Air-conditioning as a technical solution to protect inhabitants from excessive heat exposure creates the challenge of expanding indoor health effects. While air-conditioning has mostly been applied as an improvement to living conditions, health and environmental problems associated with its use frequently occurs. Therefore, this paper challenges and extends existing knowledge on sustainability related to the smart air-conditioning systems. The decrease of CO2 level in building requires an intelligent control system because energy utilisation has been legitimately connected with wellbeing and eventually to operational expenses. A building’s indoor environmental essential factors of comfort are IAQ, visual and thermal. Through an appropriate structured controller, the performance of indoor control system can be altogether improved. It merits creating innovative control techniques to optimise the indoor environment quality for air-conditioning system. The newly proposed backpropagation neural network was optimised using Matlab to control the CO2 level appropriately while carefully taking into account the performance of system controllers such as the stability, adaptability, speed response and overshoot. The controller of indoor environment was designed, and the proportional-integral-derivative control was utilised as a result of its suitability. The smart controllers were designed to regulate the parameters automatically to ensure the optimised control output. The indoor CO2 possesses an appropriate time constant and settling time of 2.1s and 27.3s, respectively. Therefore, utilising smart control techniques to exterminate various indoor health effects is expected to produce sustainable living conditions.

本文討論楊伯峻《春秋左傳注》釋《左傳》魯隱公至魯僖公時期六則有待商榷字詞，計有「季年」、「征伐以討其不然」、「不以阻隘」、「薄而觀之」、「獻狀」、「鄉役之三月」。一、「季年」專指某位國君在位最末年，非泛指最後一段時間。二、「征伐以討其不然」之「不然」有「不如此」義，「征伐以討其不然」指可征伐不遵「會」、「朝」之「禮」之諸侯。三、「不以阻隘」之「阻」、「隘」於傳文相對舉，故仍應從《春秋左傳集解》釋為同義詞。四、「薄而觀之」之「薄」仍應釋為「迫」，表現曹共公欲詳觀重耳駢脅而無禮之狀。五、「獻狀」之「獻」當讀為《說文解字》之「𤅊」，即典籍所見「讞」，有議罪、辨別是非之意。「獻狀」乃如《國語．晉語四》「誅觀狀」，謂議曹共公觀駢脅之罪。六、「鄉役之三月」之「三月」，依《左傳》「某公之某年」、「謚號之某年」句法與僖公二十八年《春秋經》、《左傳》記載，「三月」當為序數，釋為魯僖公二十八年（632 B.C.）三月。

 

This article discusses six phrases on Yáng Bó-jùn’s "Chun Qiu Zuo Zhuan Zhu" which based on the period of Lǔ Yǐn Gōng to Lǔ Xī Gōng in Zuo Zhuan. They are "jì nián", "zhēng fá yǐ tǎo qí bù rán", "bù yǐ zǔ ài", "báo ér guān zhī", "xiàn(獻) zhuàng" and "xiāng yì zhī sān yuè" 1. The meaning of the phrase "jì nián" is the last year of a certain monarch’s reign only, not the last period of his reign. 2. The phrase "bù rán" has the meaning of disobeying the agreement; therefore, the sentence "zhēng fá yǐ tǎo qí bù rán" means to go on a punitive expedition to those vassals who disobeyed the rules of "huì" and "cháo". 3. Although the words "zǔ" and "ài" in the phrase "bù yǐ zǔ ài" are contrastive meanings in "Zhuan"; however, from "Ji Jie", they should be still interpreted as synonyms. 4. The word "báo" should be interpreted as "pò" in the phrase "báo ér guān zhī". The whole meaning of this phrase is Cáo Gòng Gōng heard that Zhòng Er’s ribs were connected together, and wanted to take a look at him while he was taking a bath. That was so rude. 5. According to "Shuō Wén Jiě Zì", the word "xiàn(獻)" should read as "yàn(𤅊)" in the phrase "xiàn(獻) zhuàng". The words "yàn(𤅊)" and "yàn(讞)" are the same in ancient books and records. It means to judge the cases and distinguish right from wrong. For example, Cáo Gòng Gōng wanted to take a look at Zhòng’ Er’s ribs and that was a case so-called "Zhū guān zhuàng" in Guó Yǔ. 6. The grammar of the phrase "sān yuè" in the sentence "xiāng yì zhī sān yuè" is quite similar to the sentences "mǒu gōng zhī mǒu nián" and "shì hào zhī mǒu nián" in Zhun. According to "Jīng" and "Zhuán", "sān yuè" should be an ordinal number ,and it means the March in 632 B. C.

 
Entre Góngora y Quevedo
Authors: Jauralde Pou Pablo
Published: November 2021

This article discusses how Quevedo arrives to the silvas, how that affects the set of compositions that were written in his time, and how ideological and formal issues converged. However, due to his trip to Italy, Quevedo, who planned to write a book of silvas, changes course when he learned of Góngora’s Soledades. It is proposed that Quevedo’s Sermon estoico, which came later, is a kind of answer to the Soledades. But both of these works take different formal and ideological directions.
A figura da bruxa sob a perspectiva teórica de René Girard, na poesia de Amanda Lovelace
Authors: Hirasike Roseli , Bastazin Vera Lúcia
Published: November 2021

Este artigo aborda a figura da bruxa na literatura e sua presença nos poemas do título A bruxa não vai para a fogueira neste livro, de Amanda Lovelace. Partimos de um breve panorama dos estudos de Joseph Campbell, focando, em seguida, os conceitos de poder como objeto de desejo e a teoria do desejo mimético de René Girard. Apresentamos dados históricos e a origem etimológica do termo bruxa, importantes para a interpretação em foco, no qual o poder desejado é aquele de controle do fogo destruidor, em oposição ao fogo transformador, também presente na base dos mitos das deusas-bruxas. Finalmente, procedemos à análise da temática feminista dos poemas e os parâmetros que nos apontam o bode expiatório, surgido na linha traçada entre a bruxa das fogueiras da Inquisição e o gênero masculino na atualidade, representado metaforicamente nos poemas como “o cara dos fósforos”.

Analysis of Rectangular Reinforced Concrete Liquied Tanks by Using Yield Line Theory
Authors: Zandi Yousef , Keivani Afram
Published: November 2021

In the analysis of rectangular reinforced liquid storage tanks, a method assuming linear-elastic behavior for material can be used, i.e., the strip method, the moment coefficient method, the finite element method, etc. In the analysis of these types of tanks, tank walls can be considered as slabs. In this study, tank walls were analyzed as slabs subjected to hydrostatic loading; in the analysis, the yield line theory is used because it is more suitable for the linear inelastic behavior of reinforced concrete slabs than the ones based on the linear elastic theory. An iterative algorithm based on yield line theory is presented for the design of isotropically reinforced recrangular concrete slabs supported along all four edges. A computer program is coded which predicts the location of yield lines for the slabs depending upon certain parameters. As a result of this prediction, the manual design of such slabs can be significantly simplified by the use of the coefficient obtained by using the program. It was shown that the analytical computation of the ultimate moment per unit length requires the solution of a highly nonlinear system of equations. This difficulty was overcome by utilizing an iterative technique within the computer program. It also gives the value of the ultimate moment per unit length of the yield line.

An age-old syndrome which possesses not only multifactorial etiological origins but also often associated with high rate of remission-rebound frequency during its management time is kidney stone (termed as urolithiasis). In Ayurveda, this syndrome is called as mutrakricchra and it is one of the most distressing syndromes among the group of urinary disorder conditions attached to human beings till today. Even Acharya Sushruta, a pioneer in the art of surgery, described the root causes and management of urolithiasis. In modern medical practice, plenty of management/treatment options are available which starts from the use of uresis-promoting agent to dietary or nutritional supplement intake. Approaches developed by amalgamating the ayurvedic concept/principle with modern medical practice is a promising strategy and even welcome addition for urolithiasis management. This review provides a comprehensive insight on how the amalgamation of ayurvedic concept with modern medical practice helps in urolithiasis management.

Published: November 2021

In today’s world, cryptography techniques are used and implemented on the elementary method of finding the prime factor of large integer, which is said to be “Inevitable to Track”. But living in an era where nothing is impossible to achieve, so cryptographic techniques are exposed to both technologies’ advancement in computational power of machines and advancement in the fields of mathematics to break the notion that factoring of large integers into their prime is impossible. To cope up with the threat that cryptography will face is handled by fusion of physics into cryptography, leading to the evolution of Quantum Cryptography. It is one of the fast-growing fields in computer technology. In this paper, I am going to brief the concepts of Quantum Cryptography and how this technology has led to the development of the strategy of complete secure key distribution. The paper covers the loophole present in the modern cryptography techniques, the fundamental principle of quantum cryptography, its implementation in the real world along with the limitation faced in this field, and the possible future of quantum cryptography.

Management of Forests in the Northern Western Ghats
Authors: Ghate Ketaki
Published: November 2021

The Western Ghats in India are a UNESCO World Heritage Site and one of the "hotspots" of biologicaldiversity in the world. Looking at the physiography and climate of the Northern Western Ghats, the regionshould support Tropical semi evergreen (on Crestline) to moist deciduous type of forest (on Eastern end ofspurs) as ‘climax’ type of vegetation. But it is seen to be variedly degraded and fragmented due to use bylocal people for cultivation or intrusion by outsiders for commercial gains over the last two centuries, as wellas modern developmental pressures within the last few decades. The original forest cover and biodiversityis seen only in pockets of notified protected areas or within semiprotected areas like scared groves. Rest ofthe landscape is degraded to various seral stages depending on the degree of disturbance and is reflected insix major vegetation classes namely Rocky outcrops, Open grasslands with Scrub, Dense shrubbery, Dwarfcanopy forests, Riparian forests and Tall mature forests. Composition of species pertaining to each of theseclasses is more or less definite with some overlaps. The current article tries to illustrate the reasoning foreach of these stages along with the dominant species associated with each stage, mainly flora and birds. Ofthese stages, the last one is the protected ‘climax’ vegetation, which is the only support for ‘habitat specialist’species, some of which are threatened as per IUCN. No other seral stage can support this biodiversity. Froman ecological point of view, there is an urgent need to conserve these pockets and provide buffer for them.A detailed study may need to be undertaken to know the exact areas under such climax forest and developa policy for their protection.The article also suggests landscape-based management strategies for conservation in the NorthernWestern Ghats, based on ecological role and potential of each land class. This can be achieved throughvarious restoration techniques like soil water conservation, plantation, habitat development etc.
Growth of random errors in temperature forecasts by numerical method using centred time-differences
Authors: RAO D Y P. , RAMAMURTI K. S.
Published: November 2021

The growth of initial random errors in temperature forecasts by numerical method using centred time-differenced is investigated. Horizontal advection in one dimension is considered. Assuming that there is no correlation between the initial random errors as the different grid points and neglecting any correlation that may develop in the col1rse of computation, the random errors grow much more rapidly in this method than in forward time differencing. In both methods, correlations develop between the random errors at different grid points in the course of computation. When these are taken in to account, the growth of random errors is further enhanced in the forward differences. In the centred time-differences method, these correlations keep the random error almost at the initial level.
Oceanography of the Arabian Sea during the southwest monsoon season Part II: Stratification and circulation

Published: November 2021

The distribution of mass in the Arabian Sea during the southwest monsoon season, 1963 is presented through several vertical sections and spatial distribution charts of the thermosteric anomaly. The circulation patterns in the upper 200 m are derived. The basic feature of circulation is found to be the formation of several cyclonic and anti-cyclonic cells. Upwelling off the southwest coast of India has been explained on a more rational basis than has been assumed hitherto. It is now attributed partly due to the divergence in the current field and partly due to the cyclonic motion around Laccadive and Maldive Island.

HERITAGE CONTESTATION AND CONTEXT OF RELIGION: POLITICAL SCENARIO FROM SOUTHERN ASIA
Authors: P.B. Singh Rana
Published: November 2021

Heritage is a cultural identity to be refl ected in the purview of individual, unique and multiple layers of pluralism, especially with respect to religion, at least in Oriental cultures that maintained their traditions and continuity together with examples of contestation, destruction and also sometimes harmonious co-existence. In the span of time the layering of various cultures put their marks, which in the sequence of time turn to be the issue of confl icts due to claims and controls by the diff erent groups. As a consequence there resulted issues of representation, belongingness, control and power, dissonance and contestation. Despite all theoretic constructs and human concerns for peace and harmony the issue of dissonance dominates, especially withreference to ethnicities and religion. The religious built environments are the pitiful suff erers in such happenings of turmoil recorded every parts of the world. In South Asia the Muslim invasion in medieval period (15th to 18th centuries) had been the major force and process for destruction and superimposing Islamic structure, like in case of major sacred cities of Hindus in north India. In the areas of old culture one fi nds heritagescapes that are subject to ‘ill construction and jumbled space’ where ‘several sites appear incompatibly’. The confl icts between secularist democracy and democratic religiosity are the common phenomena in South Asian region. So on, confl icts between archaeological sites or monuments and lived cultural heritage. It may be accepted rationally that if the two communities, Hindus and Muslims, are ready not to heap defeat and humiliation with an aim to re-establish the history of the medieval times, the issues can be resolved amicably. This essay reviews the emerging literature dealing with the enduring role and context of religion in the issue of contesting heritage (mostly cultural). Emphasis is further laid on the contextual constructs of analysis, examples from diff erent parts of Southern Asia, and fi nally role of religion in policies, mitigation and management of contesting heritage.
INSTITUTIONAL CAPACITY AND POLITICAL CHALLENGE: THE CATHOLIC CHURCH IN LATIN AMERICA
Authors: R. Pattnayak Satya
Published: November 2021

With increased competition from the Protestant denominations, the Catholic Church finds itself precariously placed in Latin America in recent years. In light of the steady decline in the number of Catholics and Catholic priests in the region, many have predicted the Church’s gradual irrelevance in politics. But as this study argues, that is not exactly the case. Although the growth in Protestant populations continues unabated in Latin America, the Catholic Church has increased its involvement in educational and social welfare activities. This seems to be a long-terms strategy, and is particularly true in countries where it faces the most intense competition from other religions.
CULTURE VERSUS RELIGION: A THEORETICAL ANALYSIS OF THE ROLE OF INDIGENOUS AFRICAN CULTURE OF UBUNTU IN SOCIAL CHANGE AND ECONOMIC DEVELOPMENT IN THE POSTAPARTHEID SOUTH AFRICAN SOCIETY
Authors: Simon Mapadimeng Mokong
Published: November 2021

The question of the relationship between social values and beliefs (be them religious or cultural) and the economy has always been a subject of intense scholarly inquiry and debate. To this day, it continues to receive greater attention, especially in the contemporary era where intensifying globalisation processes have brought to light questions such as religious and cultural diversity and the challenges as well as opportunities that they present. As Ray and Sayer (1999) pointed out, there has since the dawn of the twenty first century, been a ‘cultural turn’ characterised by strong interest in questions of links between culture and economy. This article provides a critical review of perspectives on the links between culture, religion, economy and development. While greater attention is drawn to cultural values, some contrast between religion and culture is however provided to avoid tendency to confuse both concepts. Including religion is also necessary as its values, like cultural values, have social significance. Thus understanding their role has bearing on understanding that of cultural values. The central purpose of the review is to provide a basis for examining claims about the role of the indigenous African culture of ubuntu in South Africa’s post-apartheid development.
ISLAM – RUSSIAN ORTHODOX CHURCH RELATIONS AND THE STATE IN THE POST-COMMUNIST RUSSIA
Authors: Sotnichenko Alexander
Published: November 2021

After the fall of Soviet Union we can state a fact of a religious heritage in Russia. It is applied not only to the traditional religious institutions, like Moscow Patriarchy, but also to different heterodox religious movements. Now we can state a fact of the originally shaped religion policy of Moscow. Orthodox Christianity in Russia has one universally recognized center – Moscow Patriarchy. Its position is shared by 90% of Russian Christians. But we can’t say that the leaders have one consolidated opinion about the problems of the relations between Islam and Christianity. We can single out two groups; one can be called „For Islam” and the second „Against Islam”. Their followers have different views on the problems of proselytism, inter-religious dialogue and religion policy of the state and the foreign policy of Russia. The same, but much more multifaceted situation is in Russian Islam. Muslims in Russia don’t have any universally recognized authority. There are several organizations, regional or aspiring to the center position, authorities, sheikhs and popular homilists with their own opinions. Here we try to classify the main organizations and their views on the problem of a dialogue with Russian Orthodoxy, Christianity at all and the Russian State’s regional policy.

Actuality. Buckwheat is a valuable food crop with unique medicinal and dietary properties of cereal and the ability to reduce radiation damage, traditional for Ukraine. Despite this, the sown area under buckwheat is insufficient to meet the needs of the population of our country. Under the conditions of climate change, breeders face an acute question regarding the creation of competitive, highly productive varieties of edible buckwheat with increased adaptive potential. Goal. Based on the results of the competitive test of 2018–2020, to select the best high- yielding breeding sample with increased adaptive potential to biotic and abiotic environmental factors in the conditions of the northern part of the Forest-Steppe of Ukraine. Research methods. Field, laboratory, measuring and weighing. Processing the results of experimental studies was performed using Microsoft Excel 2010. Results. According to the results of the competitive test of 2018-2020 selected a breeding sample p-4/13, which over the years of competitive testing significantly exceeded the standard by 95% probability, variety Olha, and proved to be a highly productive population with high adaptive potential. This population in 2020 was transferred to the Ukrainian Institute of Plant Variety Examination for state qualification examination (Application № 20008003 dated 10.11.2020) as a new variety of buckwheat Petropavlivska. Conclusions. A highly productive, early- ripening, determinant variety of edible buckwheat Petropavlivska was created, with biological grain yield of 2.2–2.5 t / ha, weight of 1000 grains of 28.9 g, grain uniformity of 85–88%, grain yield of 72%, protein content of 14,7–15.2%.

Left-wing generation, right-wing generation. Ivan Meshekov and Ernst Jünger (preliminary notes)
Authors:   ", Sabourin Vladimir ,   St. Cyril and Methodius",   University of Veliko Tarnovo
Published: November 2021

This article is an introduction to the comparison between the constituting of the “left-wing generation” of the Bulgarian literary critic Ivan Meshekov (1891–1970) and the “right-wing generation” of the German writer Ernst Jünger (1895–1998) in the frontline experience of World War I. Both authors are emblematic figures of the leftwing and the right-wing intellectual spheres respectively, being, at the same time, black sheep in their own political camp. In the well-grounded existential and conceptual temerity of decisions which led them to a categorical generational binding of the aesthetical with the political, Ivan Meshekov and Ernst Jünger are shown to be brothers in arms in a decesionistic situation of the “lost generation” which seeks and finds itself (or finds death) on the battlefields of World War I.
