Short Paragraph on \’Thermos Flask\’ (175 Words)

The \’Thermos Flask\’ is a flask in which loss or gain of heat through conduction, convection and radiation has been reduced to a minimum. It is used for keeping a hot liquid hot and a cold liquid cold for a good length of time. The thermos flask consists of a double-walled glass flask placed on a spring within a metal casing, its mouth being closed by a cork stopper. The space between the walls is evacuated. The outer side of the inner wall and the inner side of the outer wall are silvered. The space between the vessel and the metal case is packed with felt or cork. The vaccum between the two walls of the glass bottle and the felt pad between the bottle and the metal case prevents the flow of heat due to conduction and convection. The silvered surface facing each other reduce radiation and absorption of heat to a minimum. Hence, heat can neither pass from the bottle to outside nor from outside into the bottle. Thus, a hot liquid placed in the bottle will remain hot and cold liquid cold for a sufficiently long time.

Short Paragraph on \’Diabetes\’ (125 Words)

The \’Diabetes\’ is the disease of metabolism. It is caused due to the deficiency of harmone insulin and results from the imbalance of the endocrine glands. There occurs accumulation of sugar in the blood beyond the level that the kidneys can retain and this leads to passing of sugar in urine along with the minerals and water soluble vitamins. There is starvation of body tissue which results in rapid utilization of proteins and fats of the body, and consequent loss of weight. Diabetes may be controlled by-

(a) Adjustment of diet in order to relieve stress on the pancreas.
(b) Supply of sufficient quantity of insulin, if necessary, to reduce the level of blood sugar to normal level and to rendor urine free of sugar.
(c) Administration of antidiabetic drugs to stimulate the pancreas to produce more insulin.

All living cells contain propein, and muscle tissue is primarily protein. Proteins may defined as substances composed principally of amino-acids, chemically combined. Carbon, Hydrogen, Nitrogen, Oxygen, Sulphur and in a few instances, Phosphorus are the element present in proteins. The richest sources of a protein are lean meat, cheese and eggs.
