The exponential growth in power density and miniaturization of modern electronic and mechatronic systems has intensified the need for efficient thermal management. Traditional cooling techniques, such as air-cooled heat sinks and single-phase liquid systems, are increasingly unable to manage the high heat fluxes and localized temperature gradients of high-power electronic components. This review critically examines recent advancements in cooling technologies—focusing on two-phase cooling, microchannel heat exchangers, vapor chambers, nanofluids, and phase-change materials—designed to enhance heat dissipation efficiency and system reliability..

Patient-centered care (PCC) has emerged as an important aspect of contemporary health care systems, with a focus on the delivery of health care services that meet the patients’ needs, expectations, and preferences. Despite the increasing awareness and recognition of the PCC concept in the health care field, very little research has been conducted to examine the impact of hospital management strategies on the delivery of patient-centered health care services..

This study examined the impact of hospital quality and management practices on three major outcomes: patient health results, revenue performance, and patient satisfaction in healthcare facilities. The motivation behind the study came about as a result of the increased pressure on hospitals to deliver improved patient health results while at the same time maintaining efficiency in operations and strong revenue performance. .

Postnatal care (PNC) is an important service in the prevention of maternal and child morbidity and mortality, but the utilization of PNC is not equally distributed among the tribal and disadvantaged communities in India. The objective of this study was to explore the utilization of postnatal care among Santal women in West Bengal and to identify the important factors that influence the utilization of postnatal care. A cross-sectional study was conducted among 260 Santal women who had given birth to their babies in the last six months..

This study investigates the impact of decentralized applications (DApps) on enhancing transparency and traceability in manufacturing supply chain management. Utilizing both qualitative and quantitative data collection methods, including interviews, case studies, surveys, and secondary data analysis, the research highlights the substantial benefits of DApps integration. Key findings indicate notable improvements in visibility, accuracy, speed of information sharing, stakeholder trust, compliance, and audit efficiency, as well as enhanced product tracking accuracy, issue resolution speed, raw material traceability, end-to-end supply chain visibility, and a reduction in counterfeit products. These results underscore the potential of DApps to transform supply chain operations..

The paper explores the perception of learners and teachers regarding infotainment-based English Language Teaching (ELT), in Kolkata, with particular attention to engagement, motivation, understanding, classroom interaction, usability, and learning outcomes..

This study critically explores how cyborgs in science fiction challenge, subvert, and reconfigure traditional gender roles by presenting hybrid identities that blur distinctions between human and machine, male and female. Drawing on historical and contemporary works, the paper examines how cyborg figures in texts such as Do Androids Dream of Electric Sheep?, Blade Runner, and the Terminator series disrupt established norms of identity, power, and embodiment. This research seeks to critically analyze how these narratives reshape cultural perceptions of gender. This study includes evaluating cyborg representation, interrogating gendered power dynamics, and identifying their broader sociocultural impact..

This study looks at how gender justice has changed under India's constitution since it was adopted in 1950. The Constitution laid the groundwork for government based on the initial ideas of equality and liberty, but in practice, society frequently failed to live up to its high expectations, especially when it came to resolving gender inequality. Gender justice has progressed significantly thanks to legislative efforts and judicial interpretations. Supreme Court rulings that challenged discrimination have broadened the definition of basic rights to include gender equality..

The rapid adoption of electric vehicles (EVs) necessitated the development of efficient energy recovery mechanisms to enhance driving range and overall system performance. This study aimed to develop a simplified regenerative braking system design, which will not only maximize the energy recovery but also reduce the energy recovery system complexity. The proposed solution used speed and braking demand of the vehicle as the main control parameters to distribute braking force between the regenerative and friction braking systems. A dynamic model of an EV was created and tested under various driving conditions - urban, highway and mixed driving cycles. The electric motor functioned as a generator when the car was braking to convert the kinetic energy into electrical energy and store it in the battery system. .

According to the findings of this paper, a complete examination of the function that distribution system reconfiguration plays in reducing power losses and improving system performance is presented. It makes a contribution to the continuing efforts to improve and upgrade distribution networks in order to ensure a sustainable energy future by bridging the gap between theoretical research and real implementations. In addition to paving the way for electrical grids that are smarter, more robust, and more efficient, the discoveries and approaches that were presented provide the framework for additional breakthroughs in distribution system optimization. This article discusses the actual application of the optimization approaches that have been established in real-world distribution network operations..

Active Magnetic Bearings (AMBs) are a good alternative to mechanical bearings for high-speed motor drive applications, especially because they operate contactless and cause less friction loss and better dynamic performance. This study was conducted by simulation method to analyse the performance of an Active Magnetic Bearing based high speed motor drive system. An electromagnetic force generation model, a rotor dynamics model, a displacement sensing model and a PID control model were all integrated into a mathematical model and implemented in MATLAB/Simulink. Evaluated the system under various operating conditions including nominal operation, sudden load disturbances, rotor balance and high-speed acceleration. .
