Vinyl Chloride: A Threat to Human Body
Vinyl chloride, the chemical in several of the train cars that derailed and burned in East Palestine, Ohio recently can be extremely harmful to the human liver. The liver is the body's filter for removing toxicants from the blood. Specialized cells known as hepatocytes help reduce the toxicity of drugs, alcohol, caffeine and environmental chemicals and then send away the waste to be excreted.
The chemical has been shown to cause liver cancer, as well as a nonmalignant liver disease known as TASH, or toxicant-associated steatohepatitis. Vinyl chloride is used to produce Polyvinyl Chloride (PVC), a hard plastic used for pipes, as well as in some packaging, coatings and wires.
India’s First Hybrid Rocket
Recently, India’s first hybrid-sounding rocket by private players was launched from Chengalpattu, Tamil Nadu. Martin Foundation, in association with Dr. APJ Abdul Kalam International Foundation and Space Zone India, launched the Dr. APJ Abdul Kalam Satellite Launch Vehicle Mission- 2023.
The organisations mentioned that 5,000 students were involved in the project. The selected students designed and constructed a student satellite launch vehicle (rocket) and 150 PICO satellites (satellites at a mass below 1 kg, implemented by use of modern miniaturization techniques) research experiment cubes that contained different payloads. The rocket can be used for research in weather, atmospheric conditions and radiation.
Hybrid rocket is a bipropellant rocket engine which uses propellants that are in two different states, typically liquid and solid, which when reacted, create exhaust gases suitable for rocket propulsion.
In 2022, the Space technology startup Skyroot Aerospace also sent India’s first privately developed rocket Vikram-S. It is a single-stage spin-stabilised solid propellant rocket with a mass of approximately 545 kgs.
