What is Ozone? How it is depleted by harmful gases?

Ozone (O3) is a molecule formed by three atoms of oxygen. Normally, O2 is present in atmosphere which refers to as oxygen. It is essential for all aerobic forms of life. Ozone is a deadly poison. However, at the higher levels of the atmosphere, Ozone shields the surface of the earth from ultraviolet (UV) radiation of the sun. This radiation causes severe skin problems like skin cancer, cataract, etc. Ozone is the product which we get; when the UV rays splits the oxygen (O2) atoms into O and O atoms. These splited atoms mixes with (O2) atoms to form (O3) atoms. In this way, Ozone is formed. The decrease of ozone has been linked to synthetic chemicals like chloroflurocarbons (CFCs) which are used in refrigerants, fire extinguishers and Air conditioners. Chloroflurocarbons composed of three elements:

1. Chlorine

2. Flurine

3. Carbon

1 chlorine molecule breaks upto 1 lakh molecules of ozone.

Siphon Hydroelectric Power Plant - Edu Foundation

Abstract: The invention relates to the siphon hydroelectric power plant which aimed to provide non-polluting, safe, economically feasible and industrially accessible source of energy. It comprises: atleast three tanks which are placed in a row and later filled with water, two siphon pipes which pumps water from the tanks, a turbine is placed just above the middle tank, two connecting pipes are placed at the lower portion of the power plant project which make a connection between the tanks. Claims (6): The apparatus for obtaining siphon hydroelectric energy comprising two large tanks of equal size and another tank placed in the middle which is slightly smaller than the first two. The apparatus of claim 1 further includes atleast two siphon pipes so that water can be taken from the large equal tanks into the middle tank. The apparatus of claim 1 and 2 further includes two connecting pipes at the lower portion of power plant in order to maintain the level of water in all the ta...

How Platelets Work? - Edu Foundation

When a tissue is wounded or a blood vessel is ruptured due to some injury, the blood flows through it. If not checked, it may cause an excessive loss of blood. Sometimes, this immense loss of blood even leads to death. However, the body has its own natural device of preventing the loss of blood by forming a "blood clot" which plugs the injury and stops further flow of blood, and also checks the entry of pathogenic microorganisms. The process of blood clotting is a complex process which is mainly initiated and maintained by the platelets which circulate around the body along with other blood components. In the region of injury, the platelets rupture and release a substance called thromoboplastin. It converts protein prothrombin into thrombin. Vitamin K is essential for the formation of prothrombin in liver. Thrombin then changes soluble fibrinogen protein into fibrin. The latter undergoes rapid polymerization to form long fibres. The fibres form a network over the damaged ...

What is Artificial Kidney? How it works? - Edu Foundation

Kidneys are most vital organs for survival of the organsisms. Though the kidneys remain active throughout the life, its efficiency gradually declines with normal ageing process. For example, its activity declines to about 50% by the age of 70 in human beings. The other causes of decline in the normal functioning of kidneys are diseases such as kidney infection, injury or restricted blood flow to kidneys. These abnormalities result in kidney damage and malfunctioning. A general term for decline in the performance of kidney due to a disease is kidney failure. Though it is not common, it may result to death within a couple of weeks if not treated properly. Kidney failure is often due to build up of potassium ions which causes heart failure. The failure of both kidneys immediately need medical intervention. There are two alternatives of kidney failure (i) A matching kidney from a healthy person may be transplanted, or (ii) An 'artificial kidney' machine may be employed in or...
