Ultrasound makes use of sound waves of high in pitch that humans cannot hear them. It has become a great boon to medical science. Using ultrasound, doctors can peer deep inside every part of the body without cutting it. Cardiologists can see which blood vessels are thickened or obstructed and which muscles are being starved of blood. The sound waves are used by ophthalmologists to treat tumours in the eye, as well as to relive the pressure that causes glaucoma. A Urologist use the ultrasound to pulverize kidney stones. Unlike X-rays, ultrasound has no harmful effect compared with other body imaging systems, it's also fast and portable and cheap. It eliminates screws and glues in plastic products. Ultrasound is a sound energy in the forms of high range frequency waves. It is used to locate the object.
Ultrasound technology painful operations and weeks of lying on bed are unnecessary. Ultrasound is opening up new horizons in other fields outside medicine as well. It welds trouser pockets and even stitches bed guilt. Vacuum cleaner bags and cassette are sealed by ultrasound. The ultrasound energy is used to blast out dirt and dust out of the clothes. It is used for cleaning in labs, warships, factories and jewellery stores.
Biotechnology is being looked at as a key tool in environmental clean lines. Bio remediation is the use of living organisms to render the dangerous pollutants harmless. Certain genetically engineered organisms are being developed to convert toxic material into benevolent substance. One biotech company, The institute for genomic research has developed a micro is that can absorb large amounts of radio activity. Forest research institutes are aiming at inventing new genes that can be inserted into growing trees to make them grow faster, become more resistant to diseases in a better way and withstand heat, cold and draught.
Biotechnology is the use of biological processes. That is used to manufacture the product to improve the quality of human life. Biotechnology can be divided into sub disciplines called red, white, green and blue. Red biotechnology involves medical processes such as to getting organism to produce new drugs and also generates human tissues. White biotechnology involves industrial processes such as production of chemicals. Green biotechnology involves such processes as development of pest resistant grains. Blue biotechnology involves the processes of marine encompasses and aquatic environments. Biotechnology is the advanced technology and it has potential for misuses.
