Hijama, or cupping therapy, has traversed an intricate path from ancient therapeutic traditions to its modern adaptations. Its historical significance spans across multiple civilizations, being deeply rooted in Islamic prophetic medicine and other cultural practices. A plethora of techniques, such as wet, dry, and moving cupping, emphasize its adaptability to varied therapeutic needs. Scientific evaluations hint at its potential efficacy in areas like pain mitigation, blood circulation enhancement, and, though more rigorous research is advocated for universal validation. Contemporary global health trends, technological exposures, and socio-religious factors shape its present-day perception, with notable inclinations in sports medicine and endorsements by public figures. However, concerns about safety, possible side effects, and the pressing demand for standardized practitioner training underscore the need for its judicious application. As Hijama carves its niche in the modern health paradigm, it simultaneously evokes a balance of enthusiasm, skepticism, and curiosity. This narrative encapsulates the evolution of a practice deeply anchored in tradition, highlighting the importance of scientific scrutiny, cultural appreciation, and safety protocols in its holistic reception and implementation.

The steel industry plays a vital role in global economic development, but it is also responsible for significant environmental impacts, including greenhouse gas emissions, resource depletion, and waste generation. As the world strives for sustainability, the concept of green steelmaking has emerged as a pathway to mitigate these challenges and promote a more environmentally friendly steel production process. Green steelmaking encompasses a range of practices and technologies aimed at reducing the industry's carbon footprint and minimizing its environmental impact. One key aspect of green steelmaking is the integration of renewable energy sources into the production process. By shifting away from fossil fuels and adopting clean energy alternatives such as wind, solar, or hydropower, steelmakers can significantly reduce their carbon emissions and dependence on finite resources. Another crucial element of green steelmaking is the recycling and reuse of materials. Steel is highly recyclable, and by utilizing scrap steel as a primary feedstock, the industry can reduce the need for virgin raw materials, conserve resources, and decrease energy consumption. Additionally, byproducts and waste materials from the steelmaking process, such as slag and sludge, can be repurposed for various applications, contributing to waste reduction and resource efficiency. Furthermore, green steelmaking involves the implementation of advanced technologies and process optimization. Innovative technologies like electric arc furnaces, which use electricity instead of fossil fuels for steel melting, offer higher energy efficiency and lower carbon emissions compared to traditional blast furnaces. Hydrogen-based reduction processes, which utilize hydrogen as a reducing agent instead of carbon, show promise in achieving carbon-free steel production. To support the transition to green steelmaking, collaboration, and policy support are essential. Governments and regulatory bodies can play a crucial role in incentivizing and promoting sustainable practices through supportive policies, financial incentives, and the establishment of regulatory frameworks. Collaboration between industry stakeholders, research institutions, and technology providers is also vital for knowledge sharing, research and development, and the scaling up of sustainable steelmaking solutions. In conclusion, green steelmaking represents a transformative approach to steel production, aligning with the global objectives of sustainability and environmental stewardship. By integrating renewable energy, promoting recycling, adopting innovative technologies, and fostering collaboration, the steel industry can reduce its environmental impact, contribute to climate change mitigation, and pave the way for a greener and more sustainable future.

This study discusses the viability of substituting marble debris for cement in order to save money and the environment. The usage of marble dust particles as a fine aggregate replacement in concrete is studied in this study. In concrete, marble has taken the position of fine aggregate at content levels of 0, 4, 8, 12, and 16. To examine the varied features of Marble dust concrete, five distinct series of concrete mixtures were created. Workability, compressive strength, water absorption, specific gravity, and other parameters of controlled concrete have been compared.

Because of the research that has been done over the past three decades, continuous casting is now a complex and cutting-edge technique. This study has referenced the critical numerical modeling approach of the continuous casting process. The current work explains how molten steel flows, transfers heat, solidifies, forms the shell through solidification and coupling, and more. The continuous casting process is currently a trusted industrial method for the manufacture of steel. Numerous complex processes involving fluid flow, heat transport, and structural deformation are a part of the continuous casting process. Since metallurgical techniques have recently advanced, the continuous casting process has taken over as the primary way to make steel. Steel producers are always looking for innovative, more productive manufacturing techniques in order to achieve efficient and effective output.
