represents the condition in a thick walled pipe. The area for heat flow is proportional to the radius – as may be seen‚ the area at the outside wall of the pipe is much greater than the middle. As a result the temperature gradient is inversely proportional to the radius. The heat flow ‘per unit length of pipe’ at any radius r‚ is [pic] cf. [pic] Note: Area‚[pic] Note there is no length of pipe (l) in this equation as we choose to deal with loss per unit length of pipe instead – later we shall

Scheduled Areas and Tribal Areas : Scheduled Tribes live in contiguous areas unlike other communities. It is‚ therefore‚ much simpler to have an area-approach for development activities and also regulatory provisions to protect their interests. In order to protect the interests of Scheduled Tribes with regard to land alienation and other social factors‚ provisions of ‘‘Fifth Schedule" and ‘‘Sixth Schedule"have been enshrined in the Constitution. The Fifth Schedule under Article 244(1) of Constitution

the form of a heat wave that swept across the Great Plains and the Mid West in July 1995. It represented the affect of the disaster and also the problems faced by the healthcare and public protection authorities in coping up with the situation during and after the disaster. The number of lives lost was estimated to be 522 and 733‚ count given by two sources. The heat wave struck Chicago on 11 July and it left on 16th July leading to an annihilating situation in the city with a huge loss to life. The

While‚ on 17th August 1970‚ with the experiences from the previous two attempts‚ "Venus 7" lander completed their missions on the surface of the Venus successfully. The lander gauged the atmospheric pressure on the surface of the Venus‚ which illustrated that the pressure on the Venus’ surface was at least 90 times stronger

Loss of Species Every year a new species gets placed on the endangered species list‚ extinction is a natural process but due to human activity there has been a rapid decline in the wild species population. Loss of habitat or alteration‚ hunting‚ introduction of foreign species‚ and disease are major culprits in the extinction rate. The protection of species is an important element to the survival of biodiversity as well as human sustainability. The loss of a species means humans will lose out

Research Summary Heat stroke is defined by Knochel and Ouchama (2002‚ p. 1978) as “a core body temperature that rises above 40°C (105°F) and that is accompanied by hot‚ dry skin and central nervous system abnormalities such as delirium‚ convulsions‚ or coma.” Heat stroke can be the result of either exposure to a high environmental temperature or from an elevated core temperature due to strenuous exercise. However‚ due to the presentation of an ‘unconscious unknown’ the diagnosis of heat stroke can be
