technology and school reform

Production of aromatic hydrocarbons (arenes) like benzene, toluene and xylenes. Earlier the bulk of arenes were obtained from coal tar, but now they are derived from petroleum by the process of reforming. Increasing the octane number of straight-run gasoline by increasing the proport..

Doctors use a number of simple instruments like thermometer to monitor body temperature of patients, stethoscope to listen to heart sounds, BP instrument to check the blood pressure, BP instrument to check the blood pressure and so on. But today technology has revolutionised the wor..

It is the study of principles and practices of cattle rearing and farming for better yield of milk and milk product..

: This is the latest technology which uses the principle of osmosis. It does not require electricity and maintenance is minimum. The water obtained through membrane technology is very pure and without any contamination. This type of filter is widely used in homes , hospitals an..

Introduction - Doctors use a number of simple instruments like thermometer to monitor body temperature of patients, stethoscope to listen to heart sounds, BP instrument to check the blood pressure, BP instrument to check the blood pressure and so on. But today technology has revolutionise..

Many technologies are generated out of intensive agricultural research, to increase the food production. They are grouped in three broad groups namely crop improvement, crop protection and crop production. There are three methods of crop improvement namely, selection, breeding and t..

Recombination of DNA Technology - It is the most widely used technique in genetic engineering. It involves the formation of recombinant DNA and its introduction into an appropriate host. Recombinant DNA is the DNA formed by combining DNAs from different organisms. The technique requires s..

Summary - 1) Non-invasive diagnostic techniques are those that can be applied without penetrating the skin. 2) X-rays have a remarkable ability to penetrate matter. They help to provide detailed images of dense parts of the body like bones. 3) The photographic image produced by x-radiation is calle..

It is the most widely used technique in genetic engineering. It involves the formation of recombinant DNA and its introduction into an appropriate host. Recombinant DNA is the DNA formed by combining DNAs from different organisms. The technique requires skilful handling of genetic material an..

1. To understand molecular events in biological processes such as cell differentiation and aging. 2. It can be used to make precise gene maps. 3. Useful chemical compounds can be produced example: injectable hepatitis B vaccine. 4. It has provided a broad range of tools to aid physicians in the dia..
