... and storing these wastes have been developed so they may no longer be harmful. A very advantageous way of storing radioactive wastes is by a process called 'vitrification'. Vitrification is a semi-continuous process that enables the following operations to be carried out with the same equipment: evaporation of the waste solution mixed with the ------------------------------------------------------------ 1) borosilicate: any of several salts derived from both boric acid and silicic acid and found in certain minerals such as tourmaline. additives necesary for the production of borosilicate glass, calcination and elaboration of the glass. These ...
... which can then be used to turn electric generators there must be another method. The concentrated beams of sunlight are collected in a device called a solar furnace, which acts on the same principles as a large magnifying glass. The solar furnace takes the sunlight from a large area and by the use of lenses and mirrors can focus the light into a very small area. Very elaborate solar furnaces have machines that angle the mirrors and lenses to the sun all day. This system can provide sizeable amounts of electricity and create extremely high temperatures of over 6000 degrees Fahrenheit. Solar energy generators are very clean, little waste is emitted from the ge ...
... that are simmilar to terrestrial basalts, the surface is even more weathered and rusted.The brighter areas seem to have similar but even more weatherd and rusted material that apparently contain more fine, dust-sized particles than they do the dark reigons. The mineral scapolite,which is rare on Earth,seem's wide spread; it may serve as a store for carbon dioxide in the atmosphere. Bright caps, apparntly made of frost or ice, mark the planet's polar regions . their seasonal cycle has been followed for almost two centuries .Each Martian autumn, bright clouds form over correct pole.Bellow what is called polar hood , a thin cap of carbon dioxide frost is let during au ...
... is caused by the flow of blood through the pulmonary artery, which takes blood to the lungs. The arteries are still slightly narrow, and, therefore, blood flow through them will cause a murmur. As the baby grows, the murmur will become softer and many times disappear altogether. Another common innocent murmur heard in children ages 3 to 8 years is a vibratory musical murmur called a Still's murmur. No one knows the cause of the murmur other than blood flowing through a healthy vigorous heart. The murmur is usually detected at a well-child visit or if the child comes in with fever or some other form of illness. In times of fever or illness, the murmur will be loud ...
... also considered a dolphin. Dolphins were once hunted by commercial boats for the small amount of oil that can be extracted from their body. This oil is used to lubricate small parts in watches. Cheaper oils have been found, so dolphins are not hunted for this reason anymore. Dolphins can be caught in tuna nets by accident. Since dolphins have to breath at the surface they drown in tuna nets. It is estimated that 4.8 million dolphins were killed in tuna nets from 1959 to 1972. Under pressure from animal rights activists tuna consumers will not accept tuna from canners that do not protect dolphins. Animal rights activists also believe that dolphins shouldn't be in c ...
... per year per cow. It is necessary ;however, that the producer be well educated on how to handle twinning, in order for it to be successful for them. Many agencies see twinning as an economic move upward. The American Breeder Service has made efforts to produce semen as well as embryos with high predicted breeding values available to producers. They have been recorded based on twinning probabilities and ovulation rates. A large amount of work on twinning has also been done by the Meat and Animal Research Center. Since the early eighties, they have located cattle with a high frequency of twinning and been forming a breeding foundation based on this charact ...
... from the Arabic al-kohl, which was a term used to describe eyeliner that Middle Eastern women wore. Later, the definition broadened to mean an exotic substance (Monroe 5-6). It was primarily used among ancient people for special ceremonies, magic, and medicine, and “by about 1500 BC, Egyptian doctors included beer or wine in about 15 percent of their medicines”(Monroe 8-9). Alcoholic beverages are produced through a process called fermentation using plants such as corn, rye, barley, potatoes, and grapes, and are classified by their types and proofs. Some types of alcohol are beer, ale, stout, porter, malt liquor, wine, whiskey, bourbon, gin, rum, b ...
... treat human-induced as a serious global-scale environmental threat. The overwhelming majority of scientific experts believe human-induced climate change is inevitable. The question is not whether climate will change in response to human activities, but rather where (regional pattern), when (the rate of change) and by how much (magnitude). (17,18). Alarming information and trends are leading the scientific community in this same belief. The concept of is predicting detrimental events for the future. The most prevalent issue of is the increase in overall world temperature. In the thirty year time period of 1951-1980, a 0.4C temperature increase has ...
... regarding the human mind. As most will agree, bottled emotions do more harm than good. The act of keeping feelings inside tends to create a “pressurized” effect on the brain, overloading the psyche with pent-up “garbage”. As is the case in any good romance movie, the onlooker with bottled emotions waits until the end to release everything, dramatically and emotionally releasing all her pressurized tensions. Sure, Hollywood is not the best place to get your life morals, but a lesson really can be learned here, and the same lesson can be applied to the big question at hand. “Why does he act so gay?” By now you may be realizing where I am going wit ...
... neutrons that can begin a chain reaction, each neutron that is given off could collide with another Uranium atom splitting it apart. Each of these fissioning atoms releases a very large amount of energy, and some more neutrons. This process continues causing a chain reaction withut any outside assistance, and the Uranium has "gone critical"(Martindale, 794-195). This chain reaction is the basis for how nuclear power is made. The amount of the energy that is given off in nuclear fission is astronomical. To equal the amount of energy given off when splitting some uranium the size of a golf ball, one would have to burn approximately twenty-five train cars full ...
