NATURAL CONVECTIVE MHD MASS TRANSFER FLOW PAST AN INFINITE VERTICAL POROUS PLATE EMBEDDED IN A POROUS MEDIUM WITH THERMAL DIFFUSION AND CHEMICAL REACTION
Authors: Saikia Dibya Jyoti , Ahmed Nazibuddin , Bordoloi Rajdeep
Published: February 2023

The intent of this current exploration is to examine the natural convective magnetohydrodynamics (MHD) mass transfer flow past an infinite vertical porous plate implanted in a porous medium with thermal diffusion and chemical reaction. An analytical solution for momentum, energy, and concentration equations is achieved by implementing the perturbation method. A uniform magnetic field is installed orthogonally with the plate and the fluid undergoes a normal suction velocity with the consideration that heat flux at the plate is constant. In contemplation of recording the influence of different nondimensional parameters and deliberating the flow characteristics, the computational aftermath for fluid velocity, temperature, and species concentration is portrayed graphically. Investigations divulge the fact that the increase in thermal diffusivity causes hefty falls in the temperature field and improves the concentration of the fluid. Again it is also noted that the fluid velocity and species concentration dwindle as a result of a high rate of consumption of species. The solutions obtained in this study are attained asymptotically.

Published: February 2023

Waste rubber has been widely applied in geotechnical engineering, benefiting from its light weight, high elasticity, low density, good durability and high compressibility. In this paper, the effects of rubber content (RC) and rubber size (d0) on the dynamic properties of expansive soil–rubber (ESR) were investigated by low-temperature dynamic triaxial tests. The results show that: (1) the shear stress of ESR decreases with the increase of RC with a particle size ratio of 1.3, but first decreases and then increases with a particle size ratio of 2.4; (2) the RC threshold between soil-like and rubber-like ESR is 10%; (3) the maximum shear modulus ratio of ESR occurs at RC = 10% and d0 = 0.25 mm, with the best dynamic performance; (4) the hysteretic curve of ESR was flat and elliptical, deviating upward to the right at freezing condition. In addition, different contact modes between rubber and expansive soil are proposed and the contact mechanism has been revealed.
Modelling unsaturated silty tailings and the conditions required for static liquefaction
Authors: Wang Yanzhi , Vo Thanh , Russell Adrian R.
Published: February 2023

The potential for static liquefaction of tailings is a major focus in the design and operation of tailings storage facilities. This research models the behaviour of unsaturated tailings, with a variety of degrees of saturation, addressing the propensity for static liquefaction during monotonic loading. Unsaturated triaxial tests, including constant suction conditions and constant water–air mass conditions, were performed. A bounding surface plasticity model was used to simulate the results. The constant mass condition is relevant to undrained closed-system loading, which may prevail during fast deformation after the tailings becomes unstable, when the air and water in the pore space remain locked inside the tailings. Boyle's law and hydraulic hysteresis were accounted for to model the changes of pore air and water pressures, and suction, with the change in tailings volume. Good agreement was achieved between test results and model simulations. Additional simulations to mimic rising water tables under constant total stress states in the field, situations that may trigger instabilities, are also shown. Results are added to charts which relate peak and post-liquefaction strengths, as well as collapse lines, to measures of initial state, for unsaturated conditions, which may be of use in practice.

Authors: Viswanadham Bhamidipati Venkata Surya , Saran Rishabh Kumar , Kumar Pankaj
Published: February 2023

Geotechnical structures such as levees, dykes, canals and tailing dams, when subjected to extreme climatic conditions such as flooding and drawdown, are prone to failure on the upstream and downstream sides due to transient seepage conditions. Therefore, it is imperative to physically replicate such conditions in the actual stress state. Hence, the objective of this paper is to present the performance of an in-flight simulator developed to simulate flooding and drawdown (ISFD) events at enhanced gravities. The working principle, design details, various components of the developed simulator and calibration at normal (1g) and high gravities are discussed. In this study, the calibration and performance of the ISFD set-up were demonstrated on a model levee section in a 4.5 m radius large beam geotechnical centrifuge facility at the Indian Institute of Technology Bombay, India. In total, three centrifuge model tests were conducted on a scaled-down levee section (with and without internal drainage layers) constructed with silty sand-type material to validate the ISFD capabilities. In addition, seepage and slope stability analysis for the centrifuge models was carried out using Plaxis-2D geotechnical software, which compared favourably with physically observed tests results.
Deterrence in Space
Authors: Edl András
Published: February 2023

The recent increase in space activity brought space security considerations more to the forefront. Asthe chances of conflict in space are growing, scientific research aims at finding the possibly mosteffective tools to avoid or to win conflicts in this new domain.However, equipment deployed in space, in case it is destroyed, is hard to replace and due to thegenerated debris field, it can also endanger the capabilities of the attacker. Therefore, many expertsconsider deterrence as one of the most effective methods and try to adjust it for the space domain.However, there is a fundamental difference between the Western and the Russian or Chinese conceptsof this strategy. For the latter, coercion is an acceptable and logical part of deterrence.

Published: February 2023

Im Dezember 1926 besuchte der Reichsminister des Auswärtigen Gustav Stresemann den ein paar Monate zuvor fertiggestellten Neubau der Kulturwissenschaftlichen Bibliothek Warburg (KBW) in Hamburg in der Heilwigstraße 116. Aby Warburg bedankte sich bei dem hohen Repräsentanten der Weimarer Republik «mit einem Vortrag über die Hoheitsaspekte der Briefmarke». Für die kunsthistorische Aufmerksamkeit der konventionellen Art ein ungewöhnlicher Gegenstand, präsentierte Warburg von diesen kleinen Erzeugnissen des Postverkehrs aus England und Frankreich diverse «elegante», «ansehnliche» Exemplare. Landschaften im Miniaturformat, allegorische Szenen, ausgeklügelte Herrscherporträts mit Kostümen und Gesten aus dem mythologischen Fundus waren es, die den Entwurf für Marken häufig bestimmten: Darstellungen, in denen sich für Warburg das «politische und kulturelle» Prestige des jeweiligen Landes symbolisch spiegelte.
Arkady, Archbishop of Belovodye: On the Initial Stage of His Biography
Authors:   Tomsk State University, Esipova Valeriya A.
Published: February 2023

The legend of Belovodye is widely known and has repeatedly attracted researchers' attention; however, the history of the Old Believers' Belovodye hierarchy is just beginning to be studied in detail. The biography of Arkady, Archbishop of Belovodye, has been partly reconstructed. However, only the late period of his activities has been studied in detail, the early years and the period of the formation of his “legend” are still almost unknown. The aim of this work is to systematize available data on this issue and introduce them into scholarly discourse. The State Archive of Tomsk Oblast (GATO) stores an investigation file started in 1869, when Arkady was arrested in the vicinity of Tomsk, in the Baturino village. During the search incidental to arrest of Arkady and his followers, a book collection was confiscated and partly transferred to the Tomsk Theological Seminary. In 1920 the Seminary's book collection became part of the funds of the Research Library of Tomsk State University Research Library. The data are complemented by a letter that was found between pages of another manuscript, confiscated from the Old Believers who lived in the Tomsk-Chulym taiga in 1874. Thus, there are a number of documents relating to the period of Arkady's life that has remained practically unknown until today. The information from the archival file was studied. It contains materials from the examination of the confiscated books in the Tomsk Theological Consistory; inventories containing indications of their individual characteristics have been preserved. These indications made it possible to identify two of the confiscated books, they are now stored in the Research Library of Tomsk State University. This is Izmaragd (lit. ‘emerald', 16th century) and Kanonnik (lit. ‘canon book', 19th century), with specific notes on the endpapers, made in one handwriting. The notes use the “loud” names of the “owners” (Job the Patriarch); the time of their creation is incorrectly indicated (“Written under Ivan the Terrible”). The text of Arkady's letter is published in this article. His handwriting is similar to that in ordination certificates by Arkady that were published earlier. There is also a similarly between the letter and the ordination certificates in the mentioned titles awarded by Arkady. The newly discovered materials allow reconstructing part of Arkady's biography in the period from 1869 to 1874. They also show that Arkady tested the main techniques that he used during the takeoff of his career in the Ural period while he was in Siberia. It was at this time that he already used forged certificates, confused the investigators, calling himself fictious names. The published letter demonstrates one of the stages of the formation of Arkady's “legend” and shows the transformation of the hierarchy of authorities that he built in his “legend”.
Particular Problems of the Practice of Presenting a Person for Identification: Forensic and Criminal Procedural Aspects

Published: February 2023

The article reveals a complex of problems associated with the implementation of tactics of presenting a person for identification in crime investigations. The range of problems affects methodological, forensic, and criminal procedural aspects. The object of the study was the effectiveness of the practice of implementing the tactical potential of the investigative action of presenting a person for identification. In the study, the following general scientific methods were used: analysis, synthesis, systemic and structural. The following specific scientific methods were also used: modeling, statistical analysis, comparative historical, expert assessment. The article contains the following conclusions. Differentiation of tactical techniques depending on the procedural status of the identifying person is the main vector for the development of the tactical potential of the investigative action under consideration. At the same time, one can agree that the current Criminal Procedure Code of the Russian Federation only slightly changed the wording, without introducing anything fundamentally innovative in tactical terms. In the present period, research into the forensic nature of presenting a person for identification is dominant, aimed at developing tactical practices for conducting new types of identification (by smell, voice, etc.). A significant part of the authors of scientific studies believe that the presentation of a person for identification often depends on the success of an investigation in many criminal cases. Other researchers believe that the presentation of a person for identification is an investigative action with a tactically dubious result. In our opinion, both sides present fair arguments. Therefore, in order to neutralize the position of the second group of authors, it is necessary to develop new types of presentation for identification. In the forensic theory, an undifferentiated procedure for organizing the procedure for presenting a person for identification (independent of the procedural position of the identifier) was developed and is still considered the most rational. The most “disenfranchised” participants in the criminal process are the victim and, especially, the witness as a legally oriented, conscientious figure obliged to give truthful testimony, disregarding the issues of ensuring personal safety, not caring either about their family members or those close to them. The traditional formulations of criminal procedural norms regulating the freedom of choice of actions of an identifiable person in an investigative action, in fact, do not carry freedom of choice. In some cases, there is an undeniable expediency of re-presentation for identification. The article describes both of these cases.
Impact of Coronavirus Infection Threats and Response Measures to Combat It on Disabled People as a Socially Vulnerable Category: A Thematic Literature Review
Authors:   Southern Federal University, Detochenko Lyudmila S. , Agapova Elena A. ,   Southern Federal University
Published: February 2023

In December 2019, the world faced the COVID-19 pandemic, which caused a widespread social upheaval. The negative consequences of the infection and restrictions associated with it have particularly acutely affected socially vulnerable groups of the population, including the disabled. This article attempts a thematic analysis of scientific publications on the impact of the coronavirus infection and response measures to combat it on persons with disabilities. The empirical basis was the domestic and foreign literature in Russian and English from the scientific databases Scopus, ScienceDirect, Google Academy, E-library, as well as published in journals included in the list of peer-reviewed publications of the Higher Attestation Commission of the Russian Federation. The analysis of English- and Russian-language literature suggests the relevance of research on the threats and social consequences of COVID-19. However, the emphasis on the disparity and specificity of the threats and consequences of the pandemic, and the response to it for socially vulnerable groups of the population is rather characteristic of English-language literature. English-language databases contain a larger body of scientific literature on the problems of persons with disabilities in this period. Based on the analysis of the databases, the main threats to persons with disabilities during the pandemic were identified (threats related to the availability and quality of medical services; the inability to comply with preventive measures; deterioration of mental health; socioeconomic risks; threats associated with difficulties in reducing or unavailability of services and social support; increased risks of infection in segregated living conditions; the low level of accessibility of the environment and information; the increase in violence and the transformation of “norms” in relation to persons with disabilities). Scientific research is an important resource for reducing threats during the COVID-19 period and developing fundamentally new mechanisms for protecting the rights of persons with disabilities. Insufficient attention of domestic researchers to the situation of disabled people, lack of consideration of gender, age, and nosological characteristics of various categories of disabled people during the pandemic negatively affect the development of targeted support for the population. The thematic spectrum of research on the problems of persons with disabilities during the pandemic allows us to outline research directions in the Russian reality and use the knowledge gained in the development of practical recommendations for improving social policy in relation to persons with disabilities.
Laos in international development aid flows
Authors:   Tomsk State University, Pogorelskaya Anastasia M. , Phonekeo Vinavath ,   Tomsk State University
Published: February 2023

Since the establishment of the Lao People's Democratic Republic (Lao PDR) in 1975, the development of the country has been uneven both due to domestic policy deficiencies as well as changing international environment. The aim of the article is to provide an overview of the domestic situation in the Lao PDR in connection with the position of the country at the world arena from the 1970s up to date. The study is based on the country-specific research issued abroad in the 1990s-2000s as well as individual papers provided by Russian authors in the 2000s. The sources used for the study include the World Bank and the UN agencies data as well as information from specialized bodies dealing with development including the USAID and the EEAS. The peculiarities of the political system attributed to the Lao PRD include one-party rule, state dominance on most spheres of life and high level of corruption. The economy of the country used to suffer from the land-locked character but nowadays the country strives to gain advantage from being a transit territory in the Mekong River region. Due to sharp turns in the state economic policy from nationalization and collectivization to market orientation, the economy has been rather weak. The efforts to make tourism one of the drivers of economic development along with mining, hydropower production and agriculture, were devalued by the pandemic. The opportunities for receiving education in the country are especially limited for the poor, representatives of ethnic minorities, and women. Due to the continuing growth of the population, it may become even more difficult to provide education in the country largely. The healthcare system is also understaffed and underfunded. Malnutrition is wide-spread among the poor population. However, the healthcare system has improved a lot during the last 30 years. Many social problems of the country are not duly solved partially due to large state deficit that is somehow balanced by foreign aid. Laos was acknowledged a least developed country (LDC) in 1971. Thus, Laos relied a lot on foreign aid. The volumes of official development aid provided to the Lao PDR by the OECD Development Assistance Committee in 1971-2020 changed a lot due to the changes in the main donors of development aid from France and the US at the beginning of the 1970s, then the Soviet Union and Socialist bloc countries in 1975-1990, then again Western states, Japan, UN agencies gaining the main donor position for the Lao PDR. Countering poverty and other social problems were declared the priorities for both Lao authorities and international aid donors, certain success was achieved: the average poverty rate has decreased, the GDP per capita has been growing, the public debt remained large, though. Since the country is expected to be deprived of the LDC status in 2026 due to achieving relatively good results, it is time for the Lao PDR to reformulate its domestic and foreign policy approaches.
Lenin's theory of revolution
Authors:   Moscow State Regional University, Shults Eduard E.
Published: February 2023

The article analyzes Lenin's concept in the theory of revolution. The scientific background on the basis of which Lenin created this concept, and those new basic ideas and provisions with which he enriched the theory of revolution are considered. The author considers the key provisions of the theory of revolution, developed by the beginning of the 20th century, and their evolution in Lenin's concept: definition of the phenomenon, its reasons and consequences, classification and stages of revolutions, problems of social basis of revolutions, terror in revolutions, various social, psychological and cultural factors in revolution, i.e., all that forms a complete authorial concept of the theory of revolution. In the author's opinion, Lenin was not only a recognized practitioner of revolution and the developer of the principles of the armed antigovernment struggle, but also a large theorist in the scientific development of revolutionary theory as a scientific area, and he contributed significantly to the development of the theory of revolution whose provisions had a huge impact on all subsequent research. In particular, Lenin: (1) completed Marx' definition and classification of revolutions, (2) made additions to the problem of stages and change of stages in revolutions, (3) offered a slightly different concept of the social basis of revolutions, (4) put forward the principle of “revolutionary situation” (without it no revolution, without looking at any objective reasons, will take place), 5) put forward the principle of a huge role of political factors in revolutions, (6) considered the problem of the reasons of revolutions not only in the obligatory and objective change of formations in connection with the conflict of a way of production and productive forces, but also in the light of various social factors, (7) supported and developed Marx's idea about modernization in revolution, but put forward his own principle of revolution as an instrument of accelerated modernization.

Published: February 2023

The relevance of the article is due to the need to determine the role of the cognitive paradigm in increasing the effectiveness of subject-subject interaction in the educational process of higher education, this interaction contributing to the development of the educational process's subjects with axiological priorities. The authors solve the problem of revealing empathic reserves and mechanisms of interaction between a teacher and students that allow the educational process to be carried out in an atmosphere of comfort, trust, openness, which determines humanistic semantic formations and value-based transformations of the individual. In the article, on the basis of participation seen as the opposite of domination, coercion and authoritarianism, and as a reserve for creating a favorable psychological climate for cooperation, the authors compare the basic and advanced participatory skills of the teacher. The authors define the importance of the cognitive component of empathy as a connecting link in the development of value-based awareness, understanding and regulation of educational subjects' cognitions and emotions that affect the success of their interaction. Empathy is revealed as a form of rational-emotional-intuitive reflection of another person, which predicts one's behavior in subject-subject interaction. The authors define the position of the teacher in subject-subject interaction from the perspective of the cognitive paradigm, which, in the logic of empathic conditioning of this interaction, is transformed into the role of a guide. Such a position of the teacher is formed on the basis of the development of a step-by-step algorithm for the development of the teacher's emotional identification as a structural component of empathy. Experimental results of the study of empathic reserves and mechanisms of interaction between a teacher and students are presented on the basis of a survey of 48 second-year students of two groups (Gr.07-911 and Gr.07-911k) of the Chemical Education specialty, the Institute of Chemistry named after I.M. Butlerov of Kazan Federal University, and 41 people of two groups (Gr. 3A and Gr. 3B) in the Art of Ballet and Art of Dance specialties of the final year of the Kazan Choreographic School. The survey used the method of diagnosing the level of empathic abilities of V.V. Boyko. The selected diagnostics made it possible not only to obtain the qualitative characteristics of each channel of empathy of the students and their identification, but also, most importantly, to obtain personality-oriented information about the attitudes that promote or hinder empathy in subject-subject interaction for each surveyed student.

The increasing consumption of fossil fuels and the high emission of exhaust gases have encouraged researchers to explore different approaches to reduce its consequences. Apart from focussing on the engine components, modifications on the fuel molecules can also deliver huge improvement. Using magnetic fields on the fuel line becomes one of the promising alternatives to give a better performance of the engine and produce less hazardous emissions. Previous researchers have proven that the magnetic field could enhance combustion rate by influencing the fuel molecules. After the magnetic treatment, hydrogen atoms in the hydrocarbon fuel tend to react better with oxygen molecules, thus creating more improved combustion. However, the results were varied among the researchers with huge ranges, especially in the rate of fuel-saving and emissions depending on the experiment’s setup. While many previous researchers have reported significant improvement in engine performance with the use of the magnetic fields on the fuel line, some reported insignificant effects. Despite the promising potential, this method has not received much attention from both automotive manufacturers and users. The objective of this paper is to discuss the previous studies regarding influences of the magnetic field to the hydrocarbon fuel and engine’s output. Based on the up-to-date research findings, discussion and explanations consisting of molecular reactions, important factors in influencing the changes in the engine performance and exhaust emissions are to be discussed.

Solar activity such as solar flares causes increased X-ray and ultraviolet ray flux. This event will cause sudden ionospheric disturbances (SID) and disrupts the communication systems as well as the space-based equipment on Earth. Public awareness especially to school students on the effects of solar activities towards humans on Earth is very important as the dependency of human daily life on space technology is increasing. The awareness has been conducted by the Space Science Center, Institute of Climate Change, UKM using UKM-SID™ system. Based on the program, it was found that school student experienced constraints in the process of analyzing data due to the absence of computers in schools. Therefore, UKM-SID™ system, with portable kit equipped with an interactive software to produce an easy-to-understand figure, was proposed. An algorithm was also developed to transfer the observed data onto the server in near real time. The developed Graphical Interface software showed a visualized sunrise and sunset patterns which is in agreement with the previous study. A solar flare was detected on 1 December 2020. The observed data is also successfully uploaded onto the server in near real time. Result shows that this new UKM-SID™ system is able to capture the solar flare occurrence. This new system is also at an optimal and sophisticated level compared to the technology that has been used. Hence, the researchers believe the UKM-SID™ is able to help educators, students and the general public in the learning of space science more effectively.
From Opposition Leader to Prime Minister: Giorgia Meloni and Women’s Issues in the Italian Radical Right
Authors: De Giorgi Elisabetta , Cavalieri Alice , Feo Francesca
Published: February 2023

Under the motto “God, homeland, and family”—but also by stressing one further important marker of social identity, i.e., gender—Italian radical right party leader Giorgia Meloni multiplied her party seats in parliament from 2013 onwards. After the 2022 elections, she became the first woman prime minister in Italy. Starting from an overview of the figure of Giorgia Meloni as a radical right woman leader, we explore her and her party’s position on women-related issues and their relevance while exploring, in opposition, two different contexts: representative institutions and social media. To do that, we draw on parliamentary data—bills and parliamentary questions introduced in parliament by Fratelli d’Italia—and on Meloni’s public discourse—examined in an analysis of all the tweets posted by her official Twitter account, between 2013 and 2021. As expected, a low saliency of women’s issues appears in all the types of data examined, although some of them are more exposed to the shift in attention caused by the rise of related trend topics. Both Meloni and her party are strong supporters of the “natural family” and make use of women’s issues in claiming femonationalist arguments, especially on social media. However, Meloni and her party cannot be considered as fully “neo-traditional,” as are other similar parties in Europe, but rather as a combination of “neo-traditional” and “modern-traditional.”
Seamless GPU Acceleration for C++-Based Physics with the Metal Shading Language on Apple’s M Series Unified Chips
Authors: Gebraad Lars , Fichtner Andreas
Published: February 2023

The M series of chips produced by Apple has proven a capable and power-efficient alternative to mainstream Intel and AMD ×86 processors for everyday tasks. In addition, the unified design integrating the central processing and graphics processing unit (GPU), have allowed these M series chips to excel at many tasks with heavy graphical requirements without the need for a discrete GPU) in some cases even outperforming discrete GPUs. In this work, we show how the M series chips can be leveraged using the Metal Shading Language (MSL) to accelerate typical array operations in C++. More important, we show how the usage of MSL avoids the typical complexity of compute unified device architecture (CUDA) or OpenACC memory management by allowing the central processing unit (CPU) and GPU to work in unified memory. We demonstrate how performant the M series chips are on standard 1D and 2D array operations such as array addition, single-precision A·X plus Y, and finite-difference stencils, with respect to serial and OpenMP-accelerated CPU code. The reduced complexity of implementing MSL also allows us to accelerate an existing elastic wave equation solver (originally based on OpenMP-accelerated C++) while retaining all CPU and OpenMP functionality without modification. The resulting performance gain of simulating the wave equation is near an order of magnitude for large domain sizes. This gain attained from using MSL is similar to other GPU-accelerated wave-propagation codes with respect to their CPU variants but does not come at much increased programming complexity that prohibits the typical scientific programmer to leverage these accelerators. This result shows how unified processing units can be a valuable tool to seismologists and computational scientists in general, lowering the bar to writing performant codes that leverage modern GPUs.
toponímia de origem tupi na Região Geográfica Intermediária de Rio Verde (GO)

Neste estudo, objetivou-se analisar a toponímia indígena de acidentes físicos de nove municípios da Região Geográfica Intermediária de Rio Verde (GO). Ao orientar-se por princípios teóricos e metodológicos da Toponímia, estabeleceram-se os seguintes objetivos específicos: i) verificar a etimologia e os significados dos itens lexicais que passaram a exercer a função de topônimos, como forma de buscar a motivação semântica dessas unidades e classificá-las conforme o modelo taxionômico de Dick (1990a); ii)descrever os dados em termos de produtividade no universo estudado e a estrutura morfológica; iii) comparar os nomes indígenas da região goiana com os do sul de Mato Grosso do Sul, com a intenção de averiguar se a influência de línguas indígenas é a mesma em regiões onde há comunidades autóctones atualmente. A análise demonstrou que os topônimos são, em sua maioria, motivados por elementos da vegetação e da fauna regional. O cotejamento dos dados evidenciou que topônimos de origem Tupi estão nasduas áreas comparadas. Em Mato Grosso do Sul, entretanto, a atual presença de povos indígenas confere à toponímia local características distintas, ou seja, as línguas ainda faladas por essa população interferem diretamente na toponímia da região.

Este estudio pretende realizar una breve reflexión sobre el carácter universal de las leyendas orales, teniendo en cuenta las narraciones que florecen y se multiplican en las entrañas de la enigmática y fascinante Amazonia. A través de esta literatura de tradición oral que sobresale en la región es posible conocer gran parte de la cosmovisión de los pueblos que habitan o habitaron la región y todo lo que ello conlleva. Entre otras cuestiones, las leyendas nos invitan a reflexionar sobre la importancia de preservar y dar a conocer las voces de la selva, especialmente en cuanto al cuidado del llamado “pulmón del mundo”. Así, tendremos en cuenta las realidades del universo más rural, del interior ribereño, con el anhelo de sumarnos a estas voces que, por mucho tiempo, fueron silenciadas por la “civilización” y el “progreso”. En las narraciones orales la realidad y la ficción se funden y se confunden, despertándonos todos los tipos de sentimientos. En las leyendas subrayamos la palabra como el principal remo que nos permite desplazar y avanzar a bordo de la canoa que nos lleva al encuentro de lo más recóndito de la tradición oral amazónica y nos permite escribir una página más en la historia de esta literatura, cuyo carácter es universal. De ahí que consideramos oportuno ampliar esta reflexión al ámbito de la enseñanza de Español como Lengua Extranjera – ELE, al tiempo que proponemos el uso de las leyendas orales en la clase, en los diferentes niveles y ámbitos educativos.

O artigo proposto almeja trazer à luz discussões relevantes aos campos de estudos da Literatura e da Intermidialidade a partir da apresentação de alguns achados caros à produção literária assinada por autores brasileiros provenientes do ciberespaço. Diante desse cenário, sugerimos clarificações acerca do estado de ser da área atinente às relações dialogais interartes, ancoradas nas contribuições de pensadores cujos trabalhos teóricos são pertinentes ao tema e seguidas de ilustrações do horizonte que compreende os feitos de natureza escrita, nos quais a imagem faz-se atuante em múltiplas instâncias – tanto como recurso ao desenvolvimento de uma dada narrativa eletrônica, quanto como registro manual por intermédio da linguagem verbal e, ainda, como mediação entre suportes vários, constituindo, assim, uma morada possível ao texto. Tais formas de conceber a Literatura tornam reconhecido o abraço fraterno entre arte, homem e tecnologia na contemporaneidade.
relação entre violência e a sua representação artística em Solução de dois estados (2020), de Michel Laub
Authors: Cruz Lucas Sauzem , Dutra Aylon de Oliveira , De Felippe Renata Farias
Published: February 2023

A discussão em torno da representação da violência na arte é o que impulsiona a narrativa de Solução de dois estados, romance do escritor Michel Laub, publicado em 2020. A partir do desenvolvimento dessa temática no livro, este artigo analisa de que maneira a estrutura composicional do relato favorece a construção de uma narrativa performática que instiga o leitor a refletir sobre questões suscitadas no decorrer da história. Para tal, a pesquisa baseia-se no estudo sobre realismo performático reflexivo de Ravetti (2019), tendo como base os panoramas sobre literatura brasileira contemporânea de Schollhammer (2009) e Dalcastagnè (2012); além do estudo de Pellegrini (2004) sobre literatura e violência no Brasil.
leitura moderada da Revista da Sociedade Philomathica
Authors: Esteves Gabriel
Published: February 2023

Este trabalho pretende apontar uma nova maneira de interpretar as propostas estéticas da Revista da Sociedade Philomathica (1833), órgão de divulgação da Sociedade Filomática da Academia de Direito de São Paulo, não a partir de uma perspectiva proto-romântica e ultranacionalista, como quis a historiografia literária do século XX, mas de um ponto de vista deliberadamente moderador. Pretende-se mostrar que a Philomathica, em todos os assuntos que lhe diziam respeito (literatura, filosofia, política), tendia a assumir uma postura eclética, avessa às opiniões extremadas e perfeitamente alinhada ao projeto político-cultural de outros periódicos contemporâneos como a Aurora Fluminense e O Homem e a América, jornais ligados à Sociedade Defensora da Liberdade e Independência Nacional, associação que comungava várias personalidades importantes da vida política na corte, e de onde manaria o influxo literário que deu origem a nosso romantismo moderado.
Do totem ao umbigo
Authors: Pimentel Davi Andrade
Published: February 2023

A partir do diálogo entre o livro A obscena senhora D, de Hilda Hilst, e os livros Totem e tabu e A interpretação dos sonhos, de Sigmund Freud, este artigo analisa três questões fundamentais para a estrutura narrativa do texto hilstiano acima destacado: primeira, a presença do totemismo na composição de uma imagem de Deus correlacionada à figura do animal porco; segunda, a morte possível de Deus, a sua (não) presença; e, por fim, a ideia do umbigo, que é visto ora como marca de uma hereditariedade perdida, ora como revelação do desconhecido, ora como materialidade do corpo, como algo que se pode tocar.
On a queueing inventory with common life time and reduction sale consequent to increase in age
Authors: Rof V Abdul , Krishnamoorthy A.

Consider an inventoried item for which reduction in sales price is declared as the age of the item increases. Decision to maintain sales price at the same level/reduce, is taken at stages 2, · · · , k − 1, k. On the items attaining CLT, they are sold at scrap value, provided items are still left in stock. Customer arrival forms a non-homogenous Poisson process, with rate increasing with each sales price reduction. Service time follows exponential distribution.The items are replenished according to (S, s) policy with positive lead time. Each stage of CLT is iid which follows a Phase type distribution with representation(α, S) of orderm. The k-fold convolution of this distribution is the CLT of the inventoried items. The problem is modelled as a queueing-inventory problem which is a continuous time Markov chain (CTMC). The stationary distribution of this CTMC is computed and various performance measures are discussed. A cost function is constructed to compute the optimal order quantity and reorder level.The model is compared with queueing inventory model in which the CLT follows Erlang Distribution of order k.

Mathematics teaching and learning has been a special focus in the academic discourse due to its felt complexity in teaching and learning. This felt complexity originate from the teacher preparation process itself. Covid 19 pandemic had given a drastic blow to all the educational activities. This has affected the curricular practices in an unimaginable way. An attempt is made here to examine the various problems faced by prospective teachers in online mathematics teaching and learning during the pandemic period. Samples were selected from government/aided/unaided colleges using stratified random sampling technique with the help of a questionnaire developed for the purpose. Analysis of the data has been carried out by using techniques such as percentage, t test and ANOVA. It is concluded from the study that the several hurdles and difficulties has been there specific to mathematics teaching and learning and majority of them were unhappy with the online mathematics teaching and learning.
Deep learning based missing object detection and person identification: an application for smart CCTV

Security and protection are the most crucial concerns in today’s quickly developing world. Deep Learning methods and computer vision assist in resolving both problems. One of the computer vision subtasks that allows us to recognise things is object detection. Videos are a source that is taken into account for detection, and image processing technology helps to increase the effectiveness of state-ofthe-art techniques. With all of these technologies, CCTV is recognised as a key element. Using a deep convolutional neural network, we accept CCTV data in real time in this article. The main objective is to make content the centre of things. Using the YOLO technique, we were able to detect the missing item with an improvement of 10% sparsity over the current state-of-the-art algorithm in the context of surveillance systems, where object detection is a crucial step. It can be utilised to take immediate additional action.

With so many amazing things going on in the world of science and technology, we still don't have an effective solution to ward off pests electronically. Pesticides, insecticides and other repellents are toxic and dangerous to human health. Electronic Pest Repellent (EPR) is a new technology that is cheap, environmentally friendly, effective and poses no risk to humans. Electronic pest repellents are electronic devices that are capable of producing sounds in the ultrasonic frequency range that are inaudible to the human ear but are audible to pests such as rodents, birds and insects. Sounds of this frequency (10-100 kHz) are annoying to pests and leave the place due to severe hearing impairment. The device can be used by the general public to repel mosquitoes, insects, cockroaches and by farmers to repel rodents, insects and other pests.
