Published: May 2024

Abstract. Installation errors are important factor for the contact performance of the variable hyperbolic circular arc tooth trace (VH-CATT) cylindrical gear; the study of the relationship between installation errors and contact performances is beneficial for gear vibration and noise reduction. Firstly, based on the meshing theory, the tooth surface equation and contact ellipse of the VH-CATT cylindrical gear were deduced, and the tooth surface imprinting experiment was realized. Next, the tooth contact analysis model of the VH-CATT cylindrical gear was developed to investigate the influence of the installation errors on the elliptical contact area. Then, the calculation formulas of the tooth surface gap and contact point flexibility matrix were carried out to develop the load tooth contact analysis model of the VH-CATT cylindrical gear. Finally, the influence of the installation errors on the load distribution was investigated. Research shows that the elliptical contact area of the VH-CATT cylindrical gear is a line contact within a certain range and is located in the middle section of the tooth width. The elliptical contact area of the VH-CATT cylindrical gear increases or decreases rapidly when meshing in and out, and all the installation errors have a certain influence on the elliptical contact area, except for the center distance error. The single-tooth meshing area with the installation errors is greater than that of the ideal gear pair. The load distribution area with the installation errors deviates from the middle section, except for the center distance error. The installation rotation errors around the x and y axis have a certain influence on the maximum load of the single-tooth meshing area. The research results provide a basis for improving the bearing capacity of the VH-CATT cylindrical gear and optimizing the design.

Published: May 2024

Mixed-Team-Relay (MTR) triathlon is a novel Olympic discipline whose performance determinants and tactical behaviors have barely been studied. Additionally, a regulatory change has been made to the male and female relay order for the Paris 2024 Olympics. Therefore, this study aimed to determine the performance determinants and race dynamics as a function of competitive level on the new regulated MTR triathlon. Results from 129 national teams, (516 elite triathletes) across five MTR World Triathlon Series and two MTR European Championships in 2022 and 2023, were analyzed. Split times, average speeds, time behind the race leader (gap), partial and finishing positions, pack position as well as the rank positions of every segment, relay leg, and overall race were computed. Decision tree analyses were conducted as a predictive method for the overall results, and correspondence analyses were conducted to examine the relationship between the different relay legs and segments and the finishing positions. The performance of the fourth leg was the most relevant for overall result (30%), as well as the fourth running leg (16%) and the female legs performance (7%). Medallist relay teams were characterized by displaying a differential speed lower than 0.5 and 0.83 km/h, respectively, from the best-ranking athletes in the Legs 1 and 4. Furthermore, staying in the front pack after the second swimming leg showed a great relationship with achieving a medal position. New MTR triathlon rules shift race dynamics, emphasizing individual efforts in cycling and swimming, while maintaining the crucial importance of running.

Published: May 2024

A field experiment was carried out at the Regional Research and Technology Transfer Station, Chiplima for 6 consecutive years to study the effect of drain spacing in reclamation of waterlogged areas in loamy soil under shallow water table condition. Three drain spacing of 10, 15 and 20 m and two cropping systems of rice-wheatmung and rice-mustard-sesamum were laid out for the study. 10m drain spacing was found to be more effective in regulation of excess water from the field and lowering the groundwater table than the other two. At 10m spacing, the grain yield of rice was maximum (52.47 q/ha) with highest water-use-efficiency (76.17 kg/ha/cm). The same drain spacing also resulted in highest yield and water-use-efficiency of other dry crops like wheat, mung, mustard and sesamum. 10m drain spacing not only quickly removed the excess water from the crop field (drainage coefficient is 10.76 x 1O.5cmls) but also gave maximum net return and benefit-cost ratio (Rs. 7350/ha and 1.31, respectively for rice-wheat-mung and Rs. 6637/ha and 1.29, respectively for rice-mustard-sesamum) as compared to other two drain spacing. The lowering of the groundwater table after 6 years of the experiment was maximum (30.3 cm) for the 10 m drain spacing whereas it was minimum (24.2 cm for 20 m drain spacing).

Entire cotton picking in India is manual. It is not only a slow process but involves extremely tedious hard work. Due to impending scarcity of labour, mechanization of cotton harvesting is considered to be of vital importance. A study was conducted on the performance of a two-row self-propelled cotton picker at different locations in India. The performance of John Deere 9935 cotton picker was evaluated at PAU Ludhiana and CICR, Nagpur. Tests at PAU, Ludhiana was conducted on LH 1556 having average plant height of 112.9 cm. The mean values of forward speed, effective field capacity, total harvesting loss, mechanical picking efficiency and picker efficiency were 2.62 km/h, 0.28 ha/h, 23.62 %, 75.7 % and 76.4 %, respectively. The field evaluation of cotton picker at CICR, Nagpur was conducted on seven varieties/genotypes, namely CNH 120 MB, CNH 123, CNH 155, CNH 911, CNH 2713, CNH 4736 and GSH 2. The average height of plant and lowermost boll were 85.9 cm, 86.0 cm, 98.1 cm, 81.9 cm, 73.2 cm, 77.8 cm and 86.3 cm and 9.0 cm, 10.9 cm, 21.6 cm, 11.6 cm, 16.4 cm and 12.3 cm for CNH 120 MB, CNH 123, CNH 155, CNH 911, CNH 2713, CNH 4736 and GSH 2, respectively. The mean values of forward speed, effective field capacity, fuel consumption, total harvesting loss, mechanical picking efficiency and picker efficiency were 2.203.38 km/h, 0.278-0.563 ha/h, 22.0 - 24.0 l/h, 14.29-31.74 %, 55.6 - 83.1 % and 68.3-85.7 %, respectively. The cultural practices and staggered blooming characteristics of present Indian cotton varieties poses challenge to engineers in mechanization of cotton picking. With the advent of new genotypes, it may be possible to introduce mechanical cotton pickers successfully.

Published: May 2024

Waterlogging is common in irrigated areas of Western Yamuna Canal command covering Gohana sub-division of Sonepat district of Haryana state. Probable flood water level indicating the degree of water logging was predicted by using digital elevation model (OEM) as the base and Geographic Information System (ILWIS Academic 3.0) for anaiysis. For different levels of probable flooding the percentage area that would be submerged and the volume of water to be drained had been calculated for 20 cm interval in flood stages. In this OEM based study, the volume of water to be drained was calculated by multiplying the difference between the surface elevation and flood level with the area of each pixel. A discrepancy between the predicted and actual flood water levels was found out and was attributed to either or both of the slope of the flowing water and ingress of floodwater from the neigh boring areas, which were not considered in the present study. The developed methodology will be useful in designing drainage systems in command areas, which are inundated at times due to flooding.

Published: May 2024

Rainfall data of Bhilwara district in Rajasthan state for a period of45 years were analysed from two approaches viz.; 'Meteorological' approach and 'Onset of monsoon' approach. The results revealed considerable difference in rainfall characteristics with respect to length of growing period, water surplus/ deficit and probability of intervening dry spells due to these approaches. The 'Onset of monsoon' approach is more rational as it precisely describes the actual crop environment and provides information for varying onsets of monsoon as compared to 'Meteorological' approach. The results of water balance study revealed an increase of 142.6% in water deficit due to delay in onset (31 51 SMW) as compared to normal onset of monsoon (27th SMW), whereas an increase of 35.2% and decrease of 33.7% in water surplus was recorded due to late and early onset of monsoon. The correlation studies also reveal that onset of monsoon is inversely correlated (-0.91) with duration of rainy season while positively correlated (0.83) with water deficit. Thus, the 'onset of monsoon' approach should be considered for crop planning under rainfed regions to harness more profit per unit of rainfall.

Published: May 2024

Precision seeding in nursery plug trays requires placement of single seed in each cell. In mechanical seeding, this requirement can be met by vacuum singulation of seeds and dropping one seed in individual cells. Studies were conducted to determine optimum combination of suction pressure and nozzle size for the singulated picking of tomato and capsicum seeds. Sixteen combinations of different nozzle sizes and suction pressures were evaluated for singulation and seeding of these seeds in plug trays. The suction pressure was found to influence picking of single seed the most followed by nozzle size for both, capsicum and tomato seeds. The optimum combination of suction pressure and nozzle hole size for more than 90% singles in the case of capsicum was 500 mm of water column (4.91 kPa) and 0.49 mm and for tomato it was 400 mm of water column (3.92 kPa) and 0.46 mm, respectively.

Published: May 2024

Nonlinear optimization design models were developed for field conditions to design and manage furrow irrigation system using Lewis-Kostiakov infiltration equation. The design criterion used in the models was the depth of irrigation and basic infiltration rate of the soil. The objective function of the non-expanded nonlinear model was constructed on the basis of a relationship between net returns and water requirement efficiency, and the expanded nonlinear model was developed in terms of net returns and costs. The design variables of the models were the inflow rate, length of run, inflow time, number of furrows per set and number of sets. The expanded nonlinear model gave a better representation of the design parameters and was more flexible because it permitted easy changes in the objective function than non-expanded nonlinear model. The model can be used to compare different types of furrow irrigation management strategies.

Published: May 2024

The paper is focused on the testing of material from the "Lyulyakovitsa" tailings dam situated in proximity to the town of Panagyurishte in Bulgaria. The primary objective of this study is to investigate various laboratory techniques aimed at determining essential dynamic characteristics of the studied material. This research is conducted with the goal of subsequently assessing the seismic response of the existing tailings dam. In the context of performing an equivalent linear analysis, a widely used approach in geotechnical earthquake engineering, several crucial relationships and parameters come into play. These include the material's stiffness degradation, the damping ratio, and the small-strain stiffness, expressed through the shear wave velocity. The paper describes analysis of three experiments carried out in the geotechnical laboratory "Komaba" at the University of Tokyo. These experiments introduce undrained cyclic triaxial tests conducted under identical relative density (95%) of the tailings and executed at 50 kPa, 80 kPa, and 100 kPa effective confining stress, specifically, respectively. Additionally, two distinct testing methods were employed to measure the shear wave velocity in the specimens. The findings align with certain established directions in the existing literature for characterizing the dynamic properties of granular soils. Simultaneously, they underscore the practicality of the laboratory experiments adopted for acquiring a comprehensive set of relationships and parameters.

Authors: A. Bhandare Sushama , N. Kataria Krupa , N Athole Yuvraj
Published: May 2024

Aim: To learn about the effect of patient education on anxiety and depression in patients with intracardiac devices.
Background: Advances in the management of arrhythmias and heart failure have resulted in the increasing use of cardiac implantable electronic devices (CIEDs). Surprisingly even though these devices may save the recipient's life, these are life changing implying multiple challenges in the process of psychosocial adaptation. Studies suggest almost a quarter of patients experience anxiety and depression after pacemaker implantation which in turn negatively impacts their quality of life. Lack of information may result in self-imposed restrictions affecting ordinary daily life, further increasing psychosocial issues and turning into a vicious cycle. An intervention in the form of patient education is critical for improving self-care abilities, patient outcomes and reducing avoidable hospitalizations.
Methodology: In this experimental study, there were a total of 39 participants with intracardiac devices (post-operative patients who were hemodynamically stable and follow up patients to 1 to 2 months) aged between 18 to 80 years, the outcome measures used were Cardiac Anxiety Questionnaire and Cardiac Depression Scale.
Results: The difference between the pre- and post-values within the group was determined by the Wilcoxon-signed rank test. There was a statistically significant difference in both CAQ (Z value -4.801, p- value< 0.0005) and CDS scores (Z value -5.306, p-value< 0.0005). The sub-scales of CAQ showed significant differences with Fear (Z value -4.809, p-value< 0.0005), Avoidance (Z value -3.798, p-value< 0.0005) and HFA (Z value -3.640, p-value< 0.0005).
Conclusion: This study's findings concluded that patients with intracardiac devices had a significant decline in anxiety and depression post-patient education.

Authors: Singla Ipsa , Bansal Haripriya , Oberoi Tavishi
Published: May 2024

Background- Arboviral diseases, such as chikungunya dengue and now zika represent a problem. Epidemiology of chikungunya and dengue is well known, including its social and climatic factors associated, but only few data and reports of chikungunya are available. The clinical differentiation of chikungunya from dengue is no doubt challenging since both diseases can share clinical signs and symptoms leading to potential misdiagnosis of chikungunya in areas where dengue is endemic resulting in delayed treatment and high morbidity.
Aim & Objective- To assess seroprevalence, clinical presentations and seasonal trends of chikungunya infection in this region.
Material and method- The study was conducted in the Department of Microbiology, Government Medical College, Amritsar from January 2023 to December 2023. The serum samples were subjected to IgM antibody capture enzyme linked immunosorbent assay (MAC-ELISA) for detection of anti-chikungunya virus IgM antibodies.
Result- Overall, 52% (241/465) clinical samples were positive by MAC-ELISA. Females were more affected than males and age group >45 years was mostly affected. Fever (100%) was the primary symptom. Maximum cases were detected in the months of August to October with peak in September month. Majority of the cases were reported from rural area (94.8%).
Conclusion- In this study, seroprevalence of Chikungunya was significantly high. Though Chikungunya is a self-limiting infection, increasing morbidity by Chikungunya virus infection is affecting social and economic status of individual. Thus, a community empowerment to effectively control mosquito population by employing different mosquito control measures along with personal protection is mandatory to tackle future outbreak of the disease.

Authors: Lukas Marco , Leineweber Sebastian , Reitz Birger , Overmeyer Ludger , Aschemann Alexander , Klie Benjamin , Giese Ulrich
Published: May 2024

Rubber mixing is a complex manufacturing process that poses challenges for process control due to the high number of control variables, including mixing parameter settings, rheological behavior, compound viscosity, and batch-dependent material variations. Already small deviations from the control variables can influence the compound properties, leading to increased scrap rates. To address these challenges, this paper introduces an artificial intelligence–based approach to enhance process control in rubber mixing by predicting mixing temperatures from input variables. The proposed method uses feedforward neural networks (FFNs) to enable early identification of batch-specific temperature deviations, thereby enabling systematic improvements with each new application. The FFN was trained on a diverse dataset encompassing various rubber recipes and batches. Post-training, the FFN demonstrated remarkable accuracy, achieving a mean absolute percentage error of 1.00% on the training dataset and 1.44% on the validation dataset, thereby showcasing its efficacy in predicting temperature fluctuations within the mixing process. Consequently, the FFN can determine the relevant input variables necessary to achieve specific mixing temperatures, providing a foundation for an automated control system in rubber mixing process. This paper outlines the system architecture of the FFN tailored for rubber mixing and provides a comprehensive overview of the experimental results.

Published: May 2024

The study aims to evaluate the secondary-level academic achievement and self-concept of the pupils belonging to the traditionally impoverished potter caste of the Kumbhakar Community. A self-made questionnaire evaluates the impact of academic self-concept on academic achievement in schools. The sample consists of 100 secondary school students from three schools. Results reveal that Kumbhakar community students have a moderate academic self-concept in academic achievement, with no significant gender-based differences, guardian’s occupation, and educational level. A substantial disparity exists in academic self-concept among secondary-level students based on family type and Residence, as well as a low positive correlation between academic self-concept and achievement. Moreover, this study highlights how attaining Sustainable Development Goal 4 (Inclusive Education for All) can improve students’ academic self-concept and performance in impoverished or socioeconomically backward communities by developing positive attitudes within an elusive environment and crucial interventions facilitating robust acculturation.

Published: May 2024

This study aims to create and validate a scale that measures peer collaboration among secondary school students. The study had three objectives: 1) to identify the constructs of collaboration, 2) to develop a collaboration scale, and 3) to validate the collaboration scale. The study included 363 9th-grade students, and after an extensive literature review, it identified four constructs of collaboration: social interdependence, conflict resolution, cooperation, and sharing of resources. The consistency between these constructs was found to be positive. The scale reliability was established with a Cronbach’s alpha coefficient of 0.768 and a test-retest reliability coefficient of 0.71. The content validity of the scale was also established with a Cohen kappa coefficient of 0.66. The study found that differences between boys and girls can be determined by obtaining standard scores on the collaboration scale. This new collaboration scale will be a useful tool for practitioners who use constructivist pedagogy to measure collaboration.

Mauro Guilherme Pinheiro Koury, editor-chefe da Revista Brasileira de Sociologia da Emoção - RBSE faleceu. Juntamente com os organizadores, trabalhou arduamente para que esse dossiê se concretizasse. Herdeiro da tradição sociológica de Georg Simmel, após retornar da Universidade de Glasgow, Escócia, ingressou como professor da Universidade Federal da Paraíba. Koury é daqueles intelectuais que o leitor sabia, de antemão, onde encontrá-lo; bastava ir aos encontros da Associação Brasileira de Antropologia, Associação Brasileira de Ciências Sociais, Reuniões de Antropologia do Mercosul, Associação Latino-Americana de Sociologia, além de outros eventos da área e logo se perceberia sua assiduidade. Não por acaso, Koury foi o fundador da RBSE e da Revista de Antropologia e Sociologia - Sociabilidades Urbanas (SOCURBS), foi coordenador do Grupo de Pesquisa em Antropologia e Sociologia das Emoções (GREM) e Grupo Interdisciplinar de Estudos em Imagem (GREI), assim como desbravador, no Brasil, daquilo que conhecemos por sociologia e antropologia das emoções. Koury foi quem assumiu a responsabilidade de introduzir nas universidades brasileiras uma parte significativa dos clássicos que lemos, em português, na medida em que traduziu e publicou na RBSE textos de autores como Marcel Mauss, Georg Simmel, Robert Park, Maurice Halbwachs e Eric Hobsbawn que, por falta de tradução, até então eram desconhecidos por parte do público brasileiro. Koury formou uma importante geração de intelectuais no campo das Ciências Sociais, em especial da Sociologia e Antropologia.

Resumo: Fotoetnografia faz 25 anos. O meu próprio trabalho constitui-se em um apanhado de mais de duas décadas de atividades acadêmicas para o desenvolvimento e conceituação do termo Fotoetnografia, quando em minha pesquisa de mestrado (UFRGS 1996) e depois retomado no doutorado (Universidade de Paris 7 Denis – Diderot 2002). No presente artigo, em forma de memorial, apresento atividades ainda anteriores aos anos noventa, que sempre apontaram no sentido de atividades multidisciplinares que culminaram nesse conceito hoje amplamente utilizado sobretudo no campo das ciências sociais.

Abstract: Photo-Ethnography is 25 years old. My own work constitutes more than two decades of academic activities for the development and conceptualization of the notion of Photo- Ethnography, starting in my Master's research (UFRGS 1996) and later in the Doctorate (Université Paris 7 Denis Diderot 2002). In this article, that takes the form of a memorial, I present activities even before the nineties, which always pointed towards multidisciplinary activities that culminated in this concept that is now widely used, especially in the field of social sciences.

RESUMO: Ser mulher, preta, parda, indígena e nordestina constitui-se como uma coleção de fatores que podem desencadear preconceitos que refletem sobre as crenças sobre a capacidade humana e de trabalho do gênero feminino. A mulher nordestina é marcada pela luta e pelo empoderamento, que pouco a pouco ganha espaço nas atividades econômicas e sociais, como é o caso das “Sereias”, pescadoras que sustentam seus lares nos municípios do litoral cearense. Este artigo tem como objetivo apresentar um estudo fotoetnográfico sobre o protagonismo feminino nas atividades de pesca no litoral cearense. Esse estudo teve início em 2012, com projeto fotoetnográfico apoiado pelo do Ministério da Cultura, Correios, Secretaria de Cultura do Estado do Ceará SECULT e Local Foto. Ao todo foram visitados sete municípios do litoral cearense conhecidos pela pesca artesanal de mariscos, algas e peixes. Por dois anos, tivemos a oportunidade de conhecer mulheres que protagonizam a cena pesqueira do Ceará, conhecemos suas casas, barcos, tradições, famílias e amigos. Quando imergimos no universo dessas mulheres fomos afetadas pelas suas histórias, que inspiraram esse relato.

ABSTRACT: Being a black woman, with a mixed race, indigenous and northeastern is constituted as a collection of factors that can trigger prejudices that reflect on the beliefs about the human and work capacity of the female gender. A northeastern women are marked by struggle and empowerment, which little by little gains space in economic and social activities, as is the case of the “Sereias”, fisherwomen who support their homes in the municipalities of the Ceará coast. This article aims to present a photoethnographic study on female protagonism in fishing activities on the coast of Ceará. This study started in 2012, with a photoethnographic project supported by the Ministry of Culture, Correios, Ceará State Department of Culture SECULT and Local Foto. In all, seven cities on the coast of Ceará were known for their artisanal fishing of shellfish, seaweed and fish. For two years, we had the opportunity to meet women who lead the fishing scene in Ceará, we know their houses, boats, traditions, families and friends. When we immersed ourselves in the universe of these women, we were affected by their stories, which inspired this story.

AVANÇOS E DESAFIOS DAS POLÍTICAS PÚBLICAS PARA A EDUCAÇÃO DE JOVENS E ADULTOS (EJA) NO BRASIL
Authors: Lages Rita Cristina Lima , Machado Josiane Aparecida , Sant'ana Rivânia Maria Trotta
Published: May 2024

Este estudo analisa os avanços e desafios das pesquisas e das políticas públicas sobre/para a Educação de Jovens e Adultos (EJA) no Brasil. Apesar dos progressos, como o lançamento do Programa Nacional de Integração da Educação Profissional com a Educação Básica na Modalidade de Educação de Jovens e Adultos (PROEJA) em 2007, persistem desafios como a qualidade do ensino, a evasão escolar e a falta de estrutura adequada. A EJA desempenha um papel fundamental na inclusão e equalização de oportunidades, porém, para cumprir seu papel de forma eficaz, é necessário compreender os avanços e desafios enfrentados pelas políticas públicas destinadas a essa modalidade. A metodologia se constituiu em revisão bibliográfica sobre políticas públicas para a EJA, analisando documentos e estudos que abordam a evolução e os impactos dessas políticas. Destaca-se a importância de políticas acessíveis, inclusivas e de qualidade, além da capacitação adequada dos professores, para garantir a eficácia das políticas públicas para a EJA e superar os desafios existentes.

RESUMO: Este artigo tem por objetivo relatar os resultados de um projeto de ensino chamado "Por que falar de gênero e sexualidade na escola?" desenvolvido no Instituto Federal Sul-rio- grandense - câmpus Pelotas, com alunos do ensino médio-técnico com a duração de 40 horas. O curso propôs estudos acerca de temas como gordofobia, racismo, misoginia, violências contra a comunidade LGBTIA+, relacionamentos abusivos, heteronormatividade, com o intuito de fomentar micropolíticas educacionais voltadas à valorização da diferença, convertendo o espaço educacional em um ambiente inclusivo e aberto à diferença, no qual os alunos tiveram a oportunidade de desenvolver a capacidade de convívio com a diferença, afastando-se de preconceitos e opressão. Ao tratar de assuntos que não tinham relação direta com suas realidades, foi proporcionado às estudantes um ambiente de respeito e empatia com a realidade de corpos dissidentes, o que possibilitou o entendimento dos seus próprios privilégios.

ABSTRACT: This paper aims to report the results of a teaching project called "Why talk about gender and sexuality in school?" developed at Instituto Federal Sul-rio-grandense - campus Pelotas, with high school-technical students lasting 40 hours. The course proposed studies on topics such as fatphobia, racism, misogyny, violence against the LGBTIA+ community, abusive relationships, heteronormativity, in order to foster educational micropolicies aimed at valuing difference, converting the educational space into an inclusive and open to difference environment, in which students had the opportunity to develop the ability to convivialize with difference, moving away from prejudice and oppression. When dealing with issues that were not directly related to their realities, students were provided with an environment of respect and empathy with the reality of dissenting bodies, which allowed the understanding of their own privileges.

Published: May 2024

The aim of this paper is to introduce the notions of power boundedness, Cesàro boundedness, mean ergodicity, and uniform ergodicity for a family of bounded linear operators on a Banach space. The authors present some elementary results in this setting and show that some main results about power bounded, Cesàro bounded, mean ergodic, and the uniform ergodic operator can be extended from the case of a linear bounded operator to the case of a family of bounded linear operators acting on a Banach space. Also, we show that the Yosida theorem can be extended from the case of a bounded linear operator to the case of a family of bounded linear operators acting on a Banach space.
Stress-difference index for graphs
Authors: Rajendra R. , Reddy Polaepalli Siva Kota , Harshavardhana C. N.
Published: May 2024

The stress of a vertex is a node centrality index, which has been introduced by Shimbel (1953). The stress of a vertex in a graph is the number of geodesics (shortest paths) passing through it. A topological index of a chemical structure (graph) is a number that correlates the chemical structure with chemical reactivity or physical properties. In this paper, we introduce a new topological index for graphs called stress-difference index using stresses of vertices. Further, we establish some inequalities, prove some results and compute stress-difference index for some standard graphs. Also, we found that there is a positive correlation between the stress-difference index and some physical properties of lower alkanes.
