Project Report on Green House Effect Green House Effect is heating up of earth's atmosphere due to the trapping of intra-red ray. (reflected from the earth's surface) by the carbon dioxide layer in the atmosphere is called green-house effect. The green-house effect in the atmosphere occurs due to the presence of a blanket of carbon-dioxide gas in the atmosphere. This blanket of carbon dioxide gas in the atmosphere allows the sunlight to come in freely but does not allow the intra-red radiation reflected by the earth's surface to go out. It is just because the sun light can come in freely but the intra-red rays cannot go out freely that the temperature of earth's atmosphere is raised. The rise in temperature produce gas in the by green-house effect on earth's atmosphere depends on the amount of carbon dioxide gas in the atmosphere. In other words, the proportion of carbon dioxide in atmosphere effects the temperature of atmosphere. So, if the proportion o...
PROJECT REPORT ON HUMAN DISEASES A disease is a condition of the body or apart of it in which functions are disturbed or arranged. Diseases may also be defined as morphological , physiological , psychological disturbance in the body or body parts caused by some external agencies which may be non-parasitic e.g. deficiency of nutrients or may be parasitic caused by causes, bacteria , fungi etc. The term disease means DIS-EASE or discomfort. In short it can be defined as �diseases is disorder of body�. SOURCES OF DISEASES The reservoir of human diseases are: a) Air : It is reservoir of pathogens of many diseases like, measles, mumps, tuberculosis, diphtheria etc. b) Food and Water : These are reservoir of pathogens of many diseases like, cholera, polio, typhoid, roundworm, tapeworm etc. c) Soil : It is a reservoir of ...
