... 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 with the food, Beta radiation kills various organisms such as bacteria, yeast, and insects. Gamma rays are sometimes used in science. They are used to detect Beryllium. They also played a very important role in the development of the atomic bomb. Gamma Rays can be very dangerous to use or be in contact wit ...
... a chemical found in the human brain, which directly affects the experiences of a Schizophrenic (DEA,1). On April 16, 1943, while Dr. Hofmann was measuring a fresh quantity of LSD, he accidentally dosed himself and was overcome with confusion. He was then obligated to leave work due to “a sensation of mild dizziness” and “extreme activity of imagination.”(Discovery, 2) On April 19, 1943, at exactly 4:20 pm, Dr. Albert Hofmann ingested 0.25 mg. of liquid LSD and journeyed on the first intentional “acid trip.” In 1947, Dr. Hofmann’s employers, Sandoz Laboratories, began marketing LSD in Europe. It was introduced into ...
... is released slowly into the city. The dissipation of heat energy is slowed and even stopped by the tall building walls that do not allow infrared radiation to escape as readily as do the relative level surfaces of the surrounding countryside. The slow release of heat tends to keep city temperatures higher than those of the unpaved faster cooling areas. On clear, still nights when the heat island is pronounced, a small thermal low- pressure area forms over the city. Sometimes a light breeze, called a country breeze which blows from the countryside into the city. If there are major industrial areas along the city's outskirts, pollutants are carried into the heart ...
... asteroids if we don’t know when they will strike. So after thinking about an anti-asteroid defense system, I think that our government should look into constructing one. When one thinks about what an asteroid could do to our planet it is usually a very scary thought. In the past we have been very lucky with where asteroids have hit our earth. Back in 1908 in the Tunguska region of Siberia, an object from space hit there causing miles of forest to be devastated. If that same object had hit New York, it would have probably been like a 20 megaton bomb going off in Times Square. That would have completely altered history. What makes it worse is that it is tho ...
... growth products and production of spare body parts. Firstly, selective breeding throughout the ages has served humanity in many ways. The origins of cloning lie in the agricultural history of humanity. Therefore the perceived gap between cloning and our nature are not so distant, as cloning has been the means by which humankind has cultivated flora for a millennia. In addition, selective breeding has been the means by which humankind has manipulated fauna for its own ends. In both cases genetic manipulation does serve humanity on many practical levels. Secondly, humankind has genetically engineered many species through selective breeding. The potential of cloning ...
... A supernova may radiate more energy in a few days than the Sun does in 100 million years, and the energy expended in ejecting material is much greater even than this. In many cases, including the Crab nebula supernova, the stellar remnant left behind after the explosion is a NEUTRON STAR--a star only a few kilometers in diameter having an enormously large density and consisting mainly of neutrons--or a PULSAR, a pulsating neutron star. There are two common types of supernovas, called type I and type II. Type I occurs among old stars of small mass, whereas type II occurs among very young stars of large mass. It is not known how a small-mass star can r ...
... water so the readings would still not be acceptable. Orbiting satellites cover 99 % of the Earth's surface. According to surface-based temperatures, 1997 was the warmest year on record. According to U.S. government satellites and weather balloons1997 as the seventh coolest year since satellite measurements began in 1978. Further more, satellite and balloon based information, which uses different technology, concur with each other's readings according to NASA. My opinion is that surface-based information can not be relied on until it covers more land. Also, I find it difficult to argue with two different sources that prove each other's information to be accurate. ...
... tool for astronauts in outer space. It is now a very helpful tool for cleaning our homes. The pacemaker is a form of life-support on spacecrafts, helping astronomers' hearts pump while they are outside of the Earth's atmosphere. It is used, on Earth, for those who's hearts have problems with pumping blood. Pens that write upside-down are used in space, where there is no gravity and writing with pens would otherwise be impossible. They are convenient tools on Earth when we are trying to write on vertical surfaces. A zero-gravity training system is used to help astronauts become more comfortable with the conditions in space. It is used in places such as Sport ...
... water bath. Cool the tube. 2. Wet the dialysis tubing with the beaker of distilled water. 3. Twist one end of the tubing. 4. Fold the twisted end over on itself. 5. Tie a tight knot. Leave the extra string. 6. Insert the transfer pipette (cut off top) about one third of the way into the tubing. 7. Tie a knot securely around the transfer pipette. Leave the extra string. 8. Add two transfer pipettes (two squirts) of the Gatorade solution to the tubing. 9. Add two transfer pipettes (two squirts) of the starch solution to the tubing. 10. If you spilled any solutions while transferring, carefully rinse the tubing. 11. Fill the cylinder with distilled water to about 2.5 ...
... anaerobic sites such as peat bogs. This high degree of survivability combines with another factor inherent in the nature of pollen - the large amount produced - to make pollen analysis one of the most important tools available to the archaeologist. Though one further factor in the make-up of pollen enhances its value, namely the wide morphological variation between pollen from different plant species, most of which can be detected and classified using normal laboratory equipment. Pollen analysis is a technique which demands a high level of skill on the part of the excavator, scientist and interpreter to enable it to fulfil its potential. Collection of pollen samp ...
