long term incentives

This classification is based on the most fundamental property of the elements - the atomic number, so it is more accurate. With the atomic number as the basis of this classification, the position of isotopes in one place is justified. The systematic grouping of elements into the four blocks..

In (a + b) n , let 'a' and 'b' be both positive numbers. As r increases, the factor decreases. So long as this factor is greater than 1, T r+1 remains greater tha..

It is clear that there is an inherent tendency to variation in sexual reproduction. An error in DNA copying during sexual reproduction also causes changes as we shall see. The long-term consequences of the accumulation of variations in species, is the basis for evolution and diversity in..

Satellite technology is very useful in collecting information about various factors of the atmosphere, which governs the weather and climatic conditions. An aerial photograph of the Country is shown daily on the television. It is also published daily in the newspapers. The data collected by INSAT ..

Adaptations are favourable, heritable variations or changes that enable an organism to increase its chances of survival. Such variations are the result of genetic recombinations or mutations. Adaptations can be either permanent (i.e., heritable from generation to generation) or temporary (i..

Crop yields remaining stagnant, pesticides polluting the eco-systems, increasing cost of fertilizers, reducing soil fertility, imbalance in host - parasite and predator - parasite relationships have pushed agriculture into dangerous mode. Scientists have looked back into the technologies evol..

When propagation is over a good conductor like seawater, particularly at frequencies below about 100 kHz, surface absorption is small. Also, the attenuation due to the atmosphere is small. Thus, the angle of tilt is the main determining factor in the long distance propagation such waves...

The dipole pattern of earth's magnetic field is disturbed due to solar winds. Solar winds are a stream of charged particles coming from the sun. These particles ionise the atmosphere above these poles which display a light high up in the atmosphere. This phenomenon occurring in the arctic region is..

Cartilagenous joints are slightly movable joints in which the joint surfaces are separated by some intervening substance and slight movement only is possible. These are also called ampharthroses e.g, the symphysis where a pad of cartilage unites the two pubic bones; the inter vertebral joints wi..
