Linear programming is used to find the variations in water storage of dams which generate power, thus maximising the energy got from the entire system..

Whole numbers - place value Decimals - place value Representation on a number line Equivalent/improper fractions; mixed numbers Compare and simplify fractions Decimals, percents and fractions Addition and subtraction Common and prime factors, exponents Operations on fractions an..

This gene controls a specific series of structural genes, and lies adjacent to them. It remains turned on because it is not bound by the repressor protein produced by the regulator gene. Therefore, the cistrons keep functioning, producing enzymes. The latter catalyse the synthesis of tryptophan fro..

>When we enter a darkened room from bright light, we are unable to see anything for a few moments. Within a few seconds we are able to adjust our sight to the dim light and move about easily. After vigorous exercise, the body temperature rises and there is profuse sweating. Evaporation of the sweat..

. So, the signal power progressively decreases with increasing distance. The receiver operates on the output signal from the channel in preparation for delivery to the transducer at the destination. Receiver operations include amplification to compensate for transmission loss. T..

Isothermal process is that in which the temperature of the system remains constant. Adiabatic process is where there is no exchange of heat between the system and the surrounding. Isobaric process is when the pressure on the system remains constant during any ope..

Boolean Algebra is a Mathematical structure satisfying particular laws. Boolean Algebra provides a basic logic for operations on binary numbers 0, 1. Since computers are based on a binary system, this branch of Mathematics is found to be useful for the internal working of vario..

The Application Areas of Linear Programming are: 1. Transportation Problem 2. Military Applications 3. Operation of System Of Dams 4. Personnel Assignment Problem 5. Other Applications: (a). manufacturing plants, (b). distribution centres, (c)..

Telephone Circuits - Two-way operation is essential for satisfactory telephone service, and many of the problems of the industry arise from this fact. A simplified circuit for obtaining two-way operation is shown in the below figure. This is called a local-battery system..

This gene is located adjacent to the operator gene. It has two functions. 1.The promoter gene marks the site at which the RNA polymerase enzyme binds. When the operator gene is turned on, the enzyme moves over the operator gene to reach the structural genes and the tr..
