Nuclear Reactors A nuclear reactor, formerly known as an atomic pile, is a device used to initiate and control a self-sustained nuclear chain reaction. Nuclear reactors are used at nuclear power Plants for electricity generation and in propulsion of ships. Heat from nuclear fission is passed to a working fluid (water or gas), which in … Read more
Metal In chemistry, a metal is an element that readily forms positive ions (cations) and has metallic Bonds. Metals are sometimes described as a lattice of positive ions surrounded by a cloud of delocalized electrons. The metals are one of the three groups of Elements as distinguished by their ionization and bonding properties, along … Read more

(i) Industrial wastes: Industries are the major causes for soil pollution Textiles, steel, paper, Cement, oil, dyeing and other industries are responsible for soil pollution. Toxic … Read more
REM in Toxicology: A Comprehensive Overview Rapid eye movement (REM) sleep is a crucial stage of sleep characterized by brain activity similar to wakefulness, vivid dreaming, and muscle paralysis. While REM sleep is essential for cognitive function, emotional regulation, and memory consolidation, its role in toxicology is less well-understood. However, emerging research suggests that REM … Read more
The Silent Epidemic: Diseases Caused by Environmental Degradation The Earth, our home, is facing a multitude of environmental challenges, from climate change to pollution and deforestation. These challenges are not just abstract concepts; they have a direct and devastating impact on human health, leading to a silent epidemic of diseases caused by environmental degradation. This … Read more
Understanding Cloudbursts: Phenomenon, Impact, and Response Cloudbursts, sudden and intense bursts of rainfall concentrated in a small area, are a dramatic and often destructive weather phenomenon. While the term “cloudburst” is not formally defined in meteorology, it generally refers to a rainfall event exceeding 100 millimeters (4 inches) per hour, often occurring over a short … Read more
