Authors: Zeliang Lungsang , Malakar Durga
Published: February 2025

The present study explores the undercurrents of gender equity and empowerment within educational institutions. Education is regarded as the most pivotal tool for the all-round development of individuals. Gender discrimination, especially in education, is prevalent in the world over. This study tries to understand the barriers and facilitators influencing gender parity and the empowerment of girls and women in educational settings. The study will seek to identify the factors that hinder gender equity in Nagaland, India, such as enrolment, retention, curriculum, and the impact of socio-cultural factors. There has been significant progress in the education of girls and women, but disparities persist, especially in marginalised communities. Several factors, such as poverty, sociocultural norms, infrastructure, and curriculum, continue to impede the educational advancement of women. The paper explores the necessity of a multi-faceted approach that addresses these challenges. The study presents a way forward for policymakers and stakeholders to promote gender equity and empower girls and women through education in Nagaland and the country. The present paper also tries to understand why women have little say in decision-making, political participation, and administration despite being well-educated.

Published: February 2025

Science learning must be designed so that students can understand natural phenomena that are constantly changing. This study aims to explore scaffolding strategies related to research trends, influence on learning outcomes, appropriate learning models, research designs used, and profiles of the use of scaffolding in science learning at various levels of education. The research is a systematic literature review (SLR) to collect, analyze, and compile findings on scaffolding strategies in science learning. The literature review results show that scaffolding strategies are effective in helping students understand scientific concepts better. Providing structured scaffolding to students effectively improves students’ learning outcomes. The literature review results show that in the 2014-2024 time span, research on the application of scaffolding mostly uses quantitative methods with a non-equivalent control group design. The learning model that is widely used with scaffolding is Problem-Based Learning (PBL). Scaffolding positively impacts students' cognitive and affective learning outcomes, concept understanding, science process skills, argumentation skills, critical thinking skills, higher-order thinking skills (HOTS), learning independence, learning motivation, scientific literacy, problem-solving skills, and misconceptions. The scaffolding strategies can improve science learning effectively.

Authors: Oliveira Marcus Vinícius de , Lopes Josenilton dos Santos , Reis Alcione dos , Silva Rosemar Batista da
Published: February 2025

A crescente demanda por qualidade superficial em peças usinadas eleva os custos de produção, desafiando a indústria metal-mecânica a equilibrar a qualidade dimensional e geométrica com a redução de custos. A retificação, apesar de proporcionar melhor qualidade, implica em maior tempo de usinagem e custos mais elevados. Na literatura de usinagem, tabelas frequentemente mostram acabamentos obtidos por diferentes processos, mas sem especificar o material usinado, a ferramenta de corte ou os parâmetros empregados, dificultando uma análise precisa. Para uma comparação adequada, é essencial que o material da peça, as ferramentas de corte e os parâmetros de usinagem sejam claramente definidos. Neste sentido, este trabalho visa comparar o acabamento superficial do aço ABNT 1045 nos processos de torneamento e retificação. No torneamento, foi utilizado um inserto de metal duro com Vc = 107,4 m/min, f = 0,103 mm/rot e ae = 400 µm, sem fluido de corte. Na retificação, foi empregado um rebolo de óxido de alumínio branco (AA46K6V) com Vc = 32 m/s, ae = 20 µm e 40 µm, vw = 7,5 m/min e fluido de corte. Os resultados indicaram que a rugosidade das peças retificadas foi 82 % menor em comparação com as torneadas na condição mais agressiva.
AN EXPERIMENTAL METHODOLOGY TO STUDY THE INTER-LAYER TEMPERATURE AIMING AT SELF-TEMPERING IN WAAM
Authors: Ghayour Moheb Ali , Moradi Mahmoud , Seyedkashi Seyed Mohammad Hossein , Scotti Americo
Published: February 2025

Additive manufacturing (AM) is an approach in which a model designed by CAD can be produced directly after layering. AM has high flexibility and the ability to make parts with the required final properties. One of the technologies used to produce metal parts using AM is the Wire Arc Additive Manufacturing (WAAM), which is becoming attractive to various industries due to its cheapness and high production speed. One of the challenges for producing HSLA steel built by WAAM is to moderate its microstructure brittleness, resulting from reasonable fast cooling rates of the multiple deposited layers. This can be potentially done by post-heat treatment, which is a time and resource-consuming practice. Self-tempering, as a result of the subsequent layer depositions (multilayer), is potentially another solution. One hypothesis is that self-tempering is likely to occur by controlling interlayer temperatures (IT). But IT has been handled in WAAM only to maintain the wall dimensional features constant without heat accumulation correction by forced parameter variations. Therefore, the global objective of this proposal is to study the effect of interlayer temperature (IT), and the methods of applying and controlling IT, on the wall metallurgy of a quenchable low alloy steel WAA manufactured, maintaining the same wall width as a comparison parameter, regardless of the IT value.

Published: February 2025

Este estudo investiga a aplicação da técnica de Monitoramento da Integridade Estrutural baseada em Impedância Eletromecânica (ISHM) para a detecção de falhas em estruturas de aço espessas. A pesquisa envolveu a realização de análises experimentais em três tipos de estruturas distintas: uma viga de aço, um tarugo e um eixo de usina hidrelétrica. Os resultados mostraram que a técnica ISHM foi eficaz na detecção de falhas na viga e no tarugo, com um aumento significativo na métrica CCD à medida que os danos se intensificaram. No entanto, a técnica não conseguiu identificar adições de massa no eixo da usina, o que pode ser atribuído à inadequação do equipamento de medição utilizado para essa estrutura específica. Assim, o estudo sugere a necessidade de desenvolvimento de equipamentos personalizados para melhorar a eficácia da técnica ISHM em aplicações industriais, especialmente em estruturas espessas, destacando seu potencial e suas limitações.

Published: February 2025

O monitoramento ultrassônico da integridade estrutural é um dos ensaios não destrutivos mais utilizados. A detecção de descontinuidades por meio de um dispositivo ultrassônico é realizada monitorando as reflexões sônicas transmitidas ao material por meio de um transdutor acoplado à estrutura. No presente trabalho, a técnica ultrassônica foi aplicada a uma estrutura fixa, utilizando transdutores ultrassônicos convencionais de diferentes cabeçotes fixados na estrutura a fim de identificar danos e seu crescimento. Os transdutores foram mantidos fixos diferentemente do procedimento comumente adotado para detecção de descontinuidade com a técnica ultrassônica. Os resultados preliminares demonstraram que é possível identificar a propagação dos danos utilizando o procedimento proposto, porém o posicionamento dos transdutores e o ganho previamente adotado influenciam significativamente nos sinais obtidos. Pelos resultados, pode-se inferir que a técnica pode ser explorada em diferentes condições.

Authors: Lima Euclides Antônio Pereira de , Scarafiz Guilherme , Carvalho Solidônio Rodrigues de , Borges Valério Luiz
Published: February 2025

A gaseificação é uma das tecnologias emergentes utilizadas para o tratamento de resíduos, destacando-se por ser um processo mais limpo e com menor geração de poluentes. No processo de gaseificação, a temperatura atinge aproximadamente 850º C, e o gás de síntese (syngas) gerado passa por equipamentos de controle que removem cinzas e reduzem material particulado. Além disso, sistemas de lavadores de gases e queimadores são geralmente utilizados para eliminar as impurezas restantes antes da liberação na atmosfera. Contudo, o monitoramento das emissões deve ser rigorosamente realizado em conformidade com a legislação ambiental vigente, e os pontos de amostragem precisam seguir as normas técnicas aplicáveis. No caso da chaminé do gaseificador em estudo, foi possível dimensionar os bocais de amostragem com distâncias entre as singularidades superiores às exigências normativas (mínimo de oito vezes o diâmetro interno da chaminé a montante e duas vezes a jusante) garantindo assim o cumprimento dos requisitos normativos e proporcionando um perfil adequado para a realização da amostragem isocinética das emissões atmosféricas.

Authors: Muhanad Mais , R.Baiee Wadhah
Published: February 2025

The introduction of GPS technology has led to the creation of vast amounts of spatio-temporal data, which captures the movement patterns of different things. Efficient allocation of resources to ensure user satisfaction is a crucial factor in shaping the future of urban planning and development. It is required to comprehend the factors that can contribute to the creation of methods for studying user behaviours using a substantial number of persons within a brief timeframe. It is essential to employ appropriate clustering approaches to analyze this data in order to comprehend spatio-temporal behaviours.Heatmaps offer a graphical display of changes in density across both location and Time, making them a user-friendly tool for initial data analysis and identifying areas of high activity. The Spatio-Temporal Dynamic Graph Neural Network (ST-DGNN) utilizes graph neural networks to represent the intricate connections present in spatio-temporal data, encompassing both spatial interdependencies and temporal changes. Our methodology improves the accuracy and interpretability of trajectory clustering by integrating different methods. The suggested method has been shown to identify relevant clusters effectively and reveal noteworthy spatio-temporal characteristics through experimental analysis on real-world GPS datasets. The research utilizes a dataset comprising 182 users for analysis. Numerous measures are taken to boost the clustering accuracy of the applied techniques, including addressing missing values and outliers. Additionally, this thesis introduces a framework for time estimation based on graph-based deep learning, termed Spatio-Temporal Dual Graph Neural II Networks (STDGNN). The method entails constructing node-level and edge-level graphs that depict the adjacency connections between intersections and road segments. The results showed a number of cluster changes in each period of time dependent on move users and period; for example, the (2592) cluster of period one hour.
PID CONTROLLER FOR SPEED CONTROL OF PMSM BASED ON MAYFLY OPTIMIZATION ALGORITHM
Authors: Jaber Fatimah
Published: February 2025

Permanent magnet synchronous motor (PMSM) is extensively employed in AC servo drives owing to their superior torque-to-inertia ratio, power density, efficiency, and power factor compared to other motors. So, it is a crucial point to regulate the PMSM speed. Conventional proportional, integral, and differential (PID) is a simple controller and easy to implement but it is coefficients are essentially determined by experience when used in PMSM to control the speed. This invariably produces unacceptable outcomes, in addition when it comes to low-power application drives, PID controller gains typically produce adequate results but, when it comes to high-power application drives, an untuned PID does not deliver satisfactory performance. The optimization algorithm offers an effective method to produce optimal PID gains. Therefore, to optimize the PID coefficients to regulate the PMSM speed, this study suggests a mayfly optimization algorithm (MA). Recently, the MA was introduced as a new intelligent optimization method with exceptional optimization capabilities. Nuptial dancing and random flight improve the ability of the algorithm to balance its features of exploitation and exploration while assisting in its escape from local optima. This suggested approach has been verified with MATLAB, and the outcomes are compared with the standard particle swarm optimization technique (PSO) and conventional PID. The outcomes show that compared to the standard PSO or conventional PID, the PID parameters adjusted by the MA method can produce faster speed responses and less overshoot. Furthermore, the system's optimal ITAE index value, as determined by the MA technique, is smaller (0.794) as compared to other techniques 1.503 and 1.906 respectively.
Load Deflection Analysis of Beam-Column using Total Potential Energy (TPE) Principle
Authors: Al fadul Manar , Darwash Haider , Y. Al-Ghalibi Furat
Published: February 2025

A modified TPE approach to perform finite deflection analysis of slender beam-column elements has been developed. The proposed approach utilizes the energy principal method and takes into account the geometric nonlinearity including the effects of axial force on bending stiffness, the end moments on axial stiffness (bowing), and the initial imperfection. A new equation of the deformation curve that approaches to the exact solution is used in the strain-displacement relation to obtain a more accurate beam-column response. The derived formulation of displacement of the beam-column under axial compressive load with single curvature bowing is presented with initial imperfection and different end eccentricities. The Green strain tensor equation is developed to consider higher-order bowing term. Nonlinear analysis of central finite deflection is carried out using Newton-Raphson iteration that includes high order terms of total potential energy (TPE).  The beam-column stability is verified by computing the hessian determinant of the total potential energy. The validity of the new approach is established by comparing the numerical results obtained using the proposed equations against data previously published in the literature. Outputs from the analysis indicate that the proposed approach is capable of capturing the deflection of the beam-column with enhanced accuracy, ranging from 8.5% for e = 0.025 and up to 23.5% when e = 0.125.

This paper presents an analytical framework for digital transformation in healthcare product supply chains. It aims to systematically analyze the impact of digital initiatives across the Supply Chain Operations Reference (SCOR) model's categories: Enable, Plan, Source, and Deliver. The study explores how digital technology enhances access, affordability, and adoption of healthcare products while influencing decision-making architecture and improving supply chain actor agency and accountability. The methods used in this study include a systematic analysis of digital initiatives within healthcare product supply chains, framed by the Supply Chain Operations Reference (SCOR) model, supported by case studies and real-world examples. The results revealed that digital technology has a profound impact on improving healthcare product supply chains in several key areas including enhancing product availability, improving affordability, and expediting the adoption of new health products. The paper indicates that digital solutions significantly enhance access to healthcare products by improving visibility and traceability throughout the supply chain, leading to better inventory management, fewer stockouts, and more efficient distribution. Furthermore, the findings suggest that digital interventions help reduce costs, contributing to affordability by streamlining procurement processes, minimizing transaction costs, and optimizing resource allocation. Additionally, the results indicate that digital tools accelerate the adoption of health products by enabling real-time data analytics, which supports faster decision-making and more efficient approval processes. The findings also reveal that digital technology reshapes the decision-making architecture within supply chains which allows for more decentralized, data-driven decisions that enhance the agility and responsiveness of supply chain actors. However, the results emphasize that the long-term effectiveness of digital solutions hinges on their ability to empower supply chain actors and improve accountability. The paper concludes that governments when developing digital transformation roadmaps, should prioritize areas where lack of information is the primary constraint.

They operate at a higher level, applying their talents, aptitudes, and capabilities to improve not just their well-being but also that of others and society. (Ruchi Sundriyal, Dr. Ravindra Kumar(2014)) . Almost everyone agrees that education improves life satisfaction and well-being in some way, including indirectly, by obtaining important factors that influence happiness, like better jobs, financial benefits, and improved health (Yang Dongliang, Zheng Ge, Wang Haoran, Li Mingna (2022)). Nonetheless, there is a variety of evidence about the direct impact of schooling. Education structures crucial happiness-building elements by changing various areas of personal life. Adult education has developed into lifelong learning over time, involving individuals of multiple ages and geographical locations, with an emphasis on underserved populations, such as those with low incomes. The New Education Policy (NEP) 2020, emphasises an adult education paradigm to improve life satisfaction and well-being for everyone, especially women and marginalized groups. In this research paper, the researcher aims to describe and understand the well-being and happiness of women from adult education in India. The method used in writing this article is the literature study method, where data is obtained by a series of activities related to library data collection methods, reading and recording, and processing research materials.

Authors: Noor Romy Rahwani
Published: February 2025

Purpose: This study examines the buy-versus-build dilemma in corporate accounting information systems (AIS), with a particular focus on the decision-making process and its implications for the development of these systems.

Design: This research uses a qualitative method to study The Trio Borneo Medika, a trade company in Indonesia. It includes focus group talks with various departments and analyzes the data based on themes that emerge.

Findings: The study shows that custom-built systems fit specific business needs, but they can lead to longer delivery times and operating problems. Using ready-made software speeds up system setup and enhances business processes by following the best practices in the industry. A hybrid method has been developed as a good solution by combining customized parts with standard software.

Originality/Value: This study adds to existing knowledge by offering practical advice on whether to buy or build in AIS. It shows how combining both options can help achieve a good balance between customization and efficiency.
The impact of parental expectations and social factors on exam stress among schoolchildren
Authors: Dewa Hansi Raveena Senevirathne
Published: February 2025

Exam stress is a significant concern for schoolchildren, often affecting their academic performance and mental well-being. This article examines the impact of parental expectations and social factors, such as family dynamics, cultural pressures, and socioeconomic status, on the stress levels experienced by students during exam periods. Parental expectations are often a double-edged sword, where high hopes can motivate students but also create intense pressure, leading to anxiety and burnout. Additionally, the article explores how social factors, including the support or lack of support from family, peer relationships, and the resources available within the community, shape a child's ability to cope with exam-related stress. By analyzing these elements, the study aims to provide insights into how social and familial influences intersect to either mitigate or exacerbate the pressures surrounding exams. The findings suggest that a holistic approach, involving both parents and schools, is essential for reducing stress and promoting healthier academic experiences for students.
Temporal dynamics of indoor air quality: Investigating the impact of cooking activities and ventilation efficiency in shared kitchens

Indoor air quality (IAQ) plays a pivotal role in safeguarding human health and well-being, particularly in shared spaces like hostel kitchens where cooking is frequent. This study investigates the temporal dynamics of IAQ in shared kitchens, focusing on pollutant fluctuations during cooking activities and the role of ventilation efficiency. Using advanced monitoring tools, volatile organic compounds (VOCs), Carbon Dioxide (CO2), and Air Quality Index (AQI) were analyzed over a seven-day period. Results indicate pronounced peaks in pollutant levels during morning and evening cooking hours, attributed to frying, grilling, and other high-emission activities, compounded by insufficient ventilation. Comprehensive visualizations such as scatter plots, heatmaps, and 3D scatter graphs reveal actionable insights into pollutant behavior over time. Based on these findings, interventions including advanced ventilation systems, cleaner cooking technologies, and real-time air quality monitoring are proposed. These measures aim to mitigate IAQ challenges, ensuring healthier living environments for residents.
