What is Green House Effect ?
The name "Green-house effect" comes
from the fact that this effect is use in horticulture for the up bringing of
green plant's in small house made of glass walls and glass root. The green walls
and roofs of a green-house allows the sun-light to come in freely but it does
not allows the long wavelength infrared radiations reflected by the soil, plants
and other contents of green house to go out.
Role of Carbondioxide in Green House Effect
The carbon dioxide in the atmosphere also performs another major role. The earth receives light of different wavelengths from the sun. The Ozone in the upper atmosphere absorbs most of the harmful ultraviolet radiation and lets the other wavelengths pass through.

Project Report on Drugs Addiction
"DRUGS ADDICTION"
INTRODUCTION OF "DRUGS ADDICTION"
Drug Addiction word is make by two words :
(I) Drug (II) Addiction.
What is means Drug
Any substance, other than food, used in the prevention, diagnosis, all aviation or treatment of a disease is called a drug. A drug may also be defined as a chemical which, when taken in some way after the body function. Drug is also known as a medicine. Generally, the term drugs applied to any stimulating or depressing substance that can be habituating or addictive.
Meaning of Addiction
Addiction is the habitual, psychological and physiological dependence on a substance or practice. Which is beyond voluntary control. A person who is habituated to a substance or a practice, especially a harmful one, is called an addict.
Drugs Dependence
Drugs are prescribed by physicians for the prevention or treatment of diseases, or for increasing the physical and mental performance and are withdrawn as soon as the desired effect is achieved. Repeated use of certain drugs on a periodic or continuous basis may make the body dependence. Such drugs are called psychotropic rugs. They act on the brain and alter behaviour, consciousness and capacity of perception. Hence, they are also termed mood-altering drugs. Some people start taking drugs without medical advise due to one reason or the other and become drugs dependent.
Classification of Drugs
There are a large number of drugs on which people become dependent. These are classifies into four major groups : sedatives and tranquilizers, opiate narcotics, stimulants and hallucinogens.
Project Report Malnutrition :
What is Malnutrition :
The condition in which the people become weak and sick because of insufficient and unbalanced food is called malnutrition. A large no of people in our country and other developing countries suffer from malnutrition because of poverty, lack of education, wrong notions and frequent pregnancies. The main cause of malnutrition is poverty.

Project Report Chemical Fertilizers and Manures:
Fertilizers are the sources of plant nutrients, manufactured
commercially from chemicals. They contain much higher amount of nutrients in
comparison to the manures and are, therefore, used in very small quantities.
These fertilizers may supply one or more nutrients. Chemically they may be
inorganic compounds (e.g., ammonium sulphate) or organic compounds (e.g. urea).
1. A manure is a natural
substance. It is obtained by decomposition of animal wastes such as dung (gobar)
of cattle and buffaloes and plant residues.
2. A manure contains small amounts
of essential plant nutrients such as nitrogen, phosphorus and
potassium.
5. A manure is not nutrient
specific and it tends to remove the general deficiency of the soil.
6. A manure is voluminous and
bulky so it is inconvenient to store, transport, handle and apply to the
crop.
7. A manure is cheap and is prepared in rural
homes or fields.
