.... are some of the many uses of Gamma Rays in Medicine. Gamma Rays are also Used a great deal in modern day industries. Gamma Rays can be used to examine metallic castings or welds in oil pipelines for weak points. The rays pass through the metal and darken a photographic film at places opposite weak points. In industry, Gamma rays are also used for detecting internal defects in metal castings and in welded structures. Gamma rays are used to kill pesticides and bugs in food. Gamma rays are also used in nuclear reactors and atomic bombs. Gamma rays are often used in the food industry. The radioisotopes preserve foods. Although the rays never come in contact wit .....

.... Foundation (HCF1998), cloning is a scientific process in which a strand of DNA from one organism with the egg cell of another which creates a genetically matched life form. The actual merging process between the cells is called Nuclear Transfer. In this process the nucleus of one donor cell is removed and placed into a lab dish and starved of nutrients; it is then placed into a lab dish with a fertilized egg cell. Naturally, the cell that was starved will try to fuse with the healthy cell but it will need a little help. These two cells are then electrified thereby causing the two cells to fuse together combining their genetic structures. .....

.... and in part because response to pollution appears to be so costly at individual, governmental and corporate levels. It appears that great material loss, as well as visual manifestation, have been the only ways to galvanize action towards altering and limiting technologies so that adverse chemicals and substances are no longer belched into the environment. For example, Sagan is right on the mark when he indicates that it took the reality that CFCs were destroying the sensitive but protective ozone layer to encourage large chemical companies to begin a gradual phase-out of these substances, even when scientists had already discovered the terrible effe .....

.... the theory work. The Russian scientist Konstantin Tsiolkovsky and the experimental work of the American Robert Goddard, confirmed that a satellite might be launched by means of a rocket. During the years 1943 through 1946 several studies concluded that available rockets would be unable to place a satellite into orbit. Work on rockets for missiles and upper atmosphere research was so great after World War II that by 1954 the possibility of launching a satellite was no longer in serious doubt. In October 1954 the Committee for the International Geophysical Year (IGY), announced to other countries that they were considering launching small satellite vehicles for .....

.... sensory perception, or ESP, is defined as a way of receiving information without using one of our five senses. The study of ESP is a part of a science called parapsychology. This is also called psychical research, or psi for short. Besides ESP, there is another branch of psi communication which includes the phenomenon in which an object seems to be moved by the mind alone. The mover does not touch the object which can be living or non living. This is called psychokinesis or PK. There are three accepted types of ESP, clairvoyance, precognition,and telepathy. Clairvoyance is the extra sensory perception of events that are taking place at the exact time of .....

.... spelling, handwriting, and sometimes in arithmetic. is not a result of lack of motivation, sensory impairment, inadequate instructional or environmental opportunities, or other limiting conditions, but may occur together with these conditions. Although is life-long, individuals with frequently respond successfully to timely and appropriate intervention." Definition of " develops during the first six months of gestation . Neurons are churned out in the brain's ventricular zone. Attached to fibers, the neurons travel to the cerebral cortex, which contains the language centers. Here they hit a barrier, stop and take their place in layers above previously d .....

.... from acid rain is the killing of of many plants and underwater life in thousands of lakes and streams around the world. It strips forest soils of nutrients and damages farm crops. Acid rain can also corrode stone buildings, bridges, and priceless monuments. Acid rain can also be harmful to humans because acid rain kills the crops and fish we eat, ruins homes, and the acid can release lead in the pipes and the lead could go into our drinking water. It is hard to determine where acid rain may fall next, because the wind from a pollueted area could carry pollution to another area and the acid rain could fall there. The regions effected more by acid rain is la .....

.... traits and characteristics can be identified. By marking a piece of DNA associated with a specific trait, scientists can determine the location of genes which are important for desirable traits. It is much easier to select plants and animals that have been mapped for important traits than waiting until they are fully-grown. This way, animals and plants are recognized at an earlier state whether or not they will be useful in breeding. DNA fingerprinting also makes it easier to ensure that organisms are homozygous for certain, desirable traits, rather than relying on just the phenotypes which may actually prove to be heterozygous and can, therefore, pass on t .....
