Abstract: Background-Chronic Obstructive Pulmonary Disease (COPD) and Type 2 Diabetes Mellitus (T2DM) frequently coexist because of shared risk factors, including ageing, smoking, obesity, physical inactivity, and systemic inflammation. Their coexistence contributes to impaired pulmonary function, poor glycaemic control, reduced exercise capacity, diminished quality of life, and increased morbidity. Although exercise rehabilitation is recommended for both conditions individually, evidence regarding its effectiveness in patients with both COPD and T2DM has not been comprehensively synthesised. Objective- To systematically evaluate the effects of exercise interventions on clinical outcomes in adults with comorbid COPD and Type 2 Diabetes Mellitus. Methods- This systematic review was conducted according to the PRISMA 2020 guidelines. Electronic databases including PubMed/MEDLINE, Scopus, Embase, Web of Science, Cochrane Library-PEDro, and Google Scholar were searched for studies published between January 2015 and June 2026. Randomized controlled trials, controlled clinical trials, and prospective cohort studies evaluating structured exercise interventions in adults with comorbid COPD and T2DM were included. Methodological quality was assessed using the Cochrane Risk of Bias 2 (RoB 2) tool and ROBINS-I. Due to clinical and methodological heterogeneity, a narrative synthesis was performed. Results- Twenty-five studies met the eligibility criteria. Exercise interventions, including aerobic training, resistance training, combined aerobic-resistance exercise, pulmonary rehabilitation, inspiratory muscle training, and high-intensity interval training, demonstrated consistent improvements in exercise capacity, pulmonary function, glycaemic control, respiratory muscle strength, dyspnoea, inflammatory markers, and health-related quality of life. Combined aerobic and resistance exercise delivered within pulmonary rehabilitation programmes showed the most consistent overall clinical benefits. Exercise interventions were generally safe and well tolerated, with no serious exercise-related adverse events reported. Conclusion- Current evidence supports structured exercise rehabilitation as a safe and effective non- pharmacological intervention for individuals with comorbid COPD and T2DM. Combined aerobic and resistance exercise within pulmonary rehabilitation appears to provide the greatest clinical benefit. However, larger multicentre randomized controlled trials with standardized exercise protocols and longer follow-up are needed to strengthen the evidence base.

Abstract: Delivering responsive augmented reality (AR) experiences on mobile devices requires maintaining high rendering performance while operating within the constraints of limited processing power, memory, and battery resources. This study introduces a benchmarking framework developed with Flutter that evaluates the runtime performance of AR applications using Google ARCore on a physical Android device. The proposed framework continuously records important runtime metrics, including frame rate, frame time, CPU utilisation, memory consumption, estimated power usage, and motion-to-photon (MTP) latency during live AR sessions. Six optimisation techniques—distance-based level of detail, visibility control for distant objects, adaptive rendering quality, lazy asset loading, background-isolate data export, and batched platform metric collection—can be enabled independently to examine their individual and combined impact through controlled A/B experiments. Performance evaluation was conducted on a Realme RMX5070 smartphone running Android 16 under identical environmental conditions using a Release build. Experimental results demonstrate that enabling all optimisation strategies increased the average frame rate from 92.94 FPS to 103.27 FPS, representing an improvement of approximately 11.1%. Average memory usage decreased from 286.5 MB to 267.7 MB, while mean UI frame time was reduced by 9.4%. Among the evaluated techniques, adaptive quality adjustment produced the largest individual improvement in rendering performance. CPU utilisation remained consistently close to full capacity throughout all experiments, whereas GPU utilisation metrics were unavailable because of platform restrictions. The proposed benchmarking framework offers a reproducible methodology for analysing Flutter-based mobile AR applications and provides a practical foundation for future optimisation research across different devices and AR platforms.

Abstract: The purpose of the study was to compare the stress levels of male and female among different departments of an engineering college. A total number of 179 employees both male and female in which 28 from polytechnic (18 male and 10 female). 63 from engineering (36 male and 27 female), 52 from management (27 male and 25 female), and 36 from science & technology (7 male and 29 female) have been included in the study. All males and females who were selected for the study were in the age group of 20 years to 60 years. The results of the study shows that no significant difference can be found conclusively in perceived stress levels found across gender or college type. Although minor variations were observed, particularly a slightly higher vulnerability among female teachers, however, the overall pattern indicates a uniformly moderate level of stress among teachers

Abstract: Sericulture is an agro-based rural enterprise that integrates mulberry cultivation, silkworm rearing, cocoon production, silk reeling and value-added silk processing. Its importance extends beyond silk production because the sector provides employment, income diversification and livelihood opportunities for small and marginal farmers. India is the world's second-largest producer of raw silk and produced 38,913 MT in 2023–24, of which mulberry silk contributed 29,892 MT, while Tasar, Eri and Muga contributed 1,586, 7,183 and 252 MT, respectively. Estimated cumulative employment associated with the Indian silk sector reached 9.5 million persons in 2023–24. This review quantitatively examines sericulture as a rural enterprise by comparing production, employment, labour utilization, production costs, gross and net returns, benefit–cost ratios and technological interventions. Published farm-level studies demonstrate substantial economic potential. In Dharmapuri district of Tamil Nadu, the reported total cost of sericulture was ₹279,585.80 ha⁻¹, gross income was ₹332,168.80 ha⁻¹ and net income was ₹52,583 ha⁻¹, with a benefit–cost ratio of 1.37. Labour requirements were also substantial, particularly for women during mulberry maintenance and silkworm rearing. Recent evidence further demonstrates that structured training can significantly improve adoption of sustainable sericulture practices. Among 222 farmers in West Bengal, trained farmers recorded a knowledge score of 94.12 ± 6.35 compared with 74.33 ± 8.21 among untrained farmers, while adoption scores were 71.31 ± 9.42 and 53.00 ± 10.18, respectively. The evidence indicates that sericulture can function as a sustainable rural enterprise when productivity-enhancing technologies, skill development, market access, labour availability and environmental management are integrated into production systems.

Abstract: The representation of nature has undergone significant transformation in Canadian fiction, moving from images of wilderness and geographical vastness towards complex representations of ecological crisis, environmental vulnerability, and human–nature interdependence. This paper examines this transformation through an ecocritical reading of selected Canadian fiction, focusing on Margaret Atwood's Oryx and Crake (2003), Lee Maracle's Celia's Song (2014), Cherie Dimaline's The Marrow Thieves (2017), and Waubgeshig Rice's Moon of the Crusted Snow (2018). The study investigates how Canadian writers have moved beyond representing nature as a passive landscape or national symbol and increasingly portray it as an active component of human identity, cultural memory, survival, and ethical responsibility. The analysis considers wilderness, anthropocentrism, technological intervention, climate change, Indigenous ecological knowledge, environmental justice, and community resilience. Atwood's dystopian fiction demonstrates the consequences of technological domination and the commodification of biological life, whereas Maracle's work foregrounds relationality between humans, land, animals, and community. Dimaline connects ecological catastrophe with colonial histories and Indigenous displacement, while Rice explores energy dependence and the significance of local ecological knowledge during social disruption. The paper argues that contemporary Canadian fiction represents a movement from the idea of nature as wilderness towards an understanding of nature as an interconnected ecological system in which human survival is inseparable from environmental health. Through this transformation, Canadian fiction contributes to the development of ecological consciousness and challenges conventional anthropocentric understandings of the human–nature relationship.
