Item Climate change and stock market: The systematic review for future research using TCCM and meta-analysis(Elsevier Ltd, 2025) A, A.; V, G.B.The Intergovernmental Panel on Climate Change (IPCC) and the 2016 Paris Agreement have significantly heightened global awareness of environmental issues, stimulating extensive discussions on the intersection of climate change and financial markets in major economies. This study utilized a comprehensive keyword-based database search strategy to examine existing research on climate change and the stock market, while also providing suggestions for future research avenues. From an initial pool of 1992 papers indexed in Scopus and Web of Science, 138 articles published in A* and A-rated journals on the Australian Business Deans Council Journal Quality List (ABDC-JQL) were identified as relevant for analysis. To uncover prevailing trends in this area of research, the study employed the Theory, Context, Characteristics, and Methods (TCCM) framework and the Meta regression analysis alongside the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines during the screening process. The findings indicate that rising ecological uncertainty is likely to significantly impact corporate performance, which, in turn, could negatively influence stock market dynamics. These results highlight a crucial direction for future research into the interplay between climate change and stock market behavior. © 2025 The Author(s)Item Experimental investigation of rotor wound multi disc magneto-rheological fluid brake(SAGE Publications Ltd, 2025) Bhat, S.H.; A, A.; Naveen, S.; Kumar, H.; M, A.Magneto-Rheological fluid (MRF), known for changing properties under a magnetic field, is ideal for brakes and dampers in magnetically controlled devices. This research presents a novel design for a 10-disc MR brake using in-house Magneto-Rheological Fluid (MRF), distinguished by its integration of electromagnet windings directly onto the brake shaft. Magneto-static analysis, performed using Finite Element Method Magnetics (FEMM) software, optimized the material selection and dimensions, enhancing the magnetic field distribution across the MRF gap and maximizing braking torque. The design, with rotor windings and a consistent MRF gap, generates a uniform magnetic field, significantly boosting performance. Theoretical braking torque was estimated using Bingham plastic model for MRF characterization, aligning well with experimental results. The compact 10-disc MR brake design, weighing 1.19 kg, shows robust torque performance across varying current levels. Remarkably, prior research had not integrated electromagnet windings directly on the rotor of MR brake, marking this study as pioneering in advancing MR brake performance. © The Author(s) 2025.
