.... It is long-haired and silvery gray in eastern coastal regions but short-haired and dark gray inland. The red kangaroo, which is found throughout Australia's interior grasslands, is the largest and most powerful species. A male may attain a head-body length of 1.5 m; have a tail 1 m long; stand 2 m tall; and weigh 90 kg. A gray kangaroo can clear more than 9 m (30 feet) at a bound and attain a speed of 48 kilometres per hour. The wallaroo, a smaller and stockier animal, may be dark gray to pinkish brown; it lives in rocky country throughout Australia except Victoria. These large kangaroos travel in groups (mobs) under the leadership of the lar .....

.... and with many other sources and the dangers involved, the disadvantages of nuclear power far outweigh the benefits. Alternative sources of energy are making their way into the highly competitive field of electricity production. With the wealth of sources such as solar, wind, hydro or geothermal the dangers involved with fission could be solved by adopting these newer, safer methods. A main source of energy that could lead the way for the near future is solar energy. It is clean efficient and is already a large part of American and Canadian electricity production. "Solar energy already supplies about 6% of the nation's [U.S.A] energy ... the indust .....

.... roughly $35 a bottle, and is distributed by many manufacturers. Creatine serves as an energy reserve in muscle cells. Muscular contraction is powered by the breakdown of ATP (adenosine triphosphate) to ADP (adenosinediphosphate). When all the ATP is broken down, creatine phosphate in the muscle donates a phosphate group to ADP, and further energy reactions can occur. Creatine Monohydrate is a precursor to creatine phosphate. By supplementing with CM, CP levels in muscle apparently are maximized, and more muscular work can occur, since there are greater energy reserves to use. Approximately 95% of the body's creatine supply is found in the skelet .....

.... requires a large, cumbersome antenna to focus them into a narrow radar beam. The British showed that microwaves, with their short wavelength, could be focussed ina narrow beam with an antenna many times smaller. This enabled them to make more effective use of radar since an antenna could be carried on aircraft, ships and mobile ground stations. This characteristic of microwaves, the efficiency with which they are concentrated in a narrow beam, is one reason why they can be used in cooking. You can produce a high-powered microwave beam in a small oven, but you can't do the same with radio waves, which are simply too long. Microwaves and th .....

.... surface. All of these activities are unfavorably altering the composition of the biosphere and the Earth's heat balance. If we do not slow down our use of fossil fuels and stop destroying, the forests, the world could become hotter than it has been in the past million years. Average global temperatures have risen 1 degree Fahrenheit over the last century. If carbon dioxide and other greenhouse gases continue to spill into the atmosphere, global temperatures could rise five to 10 degrees by the middle of the next century. The warning will be the greatest at the higher latitudes of the Northern Hemisphere, with the largest temperature rises occurring i .....

.... Superfluidity. Cryogenics first came about in 1877, when a Swiss Physicist named Rasul Pictet and a French Engineer named Louis P. Cailletet liquefied oxygen for the first time. Cailletet created liquid oxygen in his lab using a process known as adiabatic expansion, which is a "thermodynamic process in which the temperature of a gas is expanded without adding or extracting heat from the gas or the surrounding system"(Vance 26). At the same time Pictet used the "Joule-Thompson Effect," a thermodynamic process that states that the "temperature of a fluid is reduced in a process involving expansion below a certain temperature and pressure"(McClintock .....

.... B. burgdorferi do not live in water, soil, or plants. Borrelia grow slowly compared to most bacteria. They elongate for 12 to 24 hours before dividing into two cells. B. burgdorferi is approximately 20 to um long and 0.2 to 0.25 um wide, with 7 to 11 flagella. More than 30 proteins are contained within B. burgdorferi1. This bacteria uses white-footed mice, mosquitoes, and deer as their hosts. This disease does not discriminate between sex and age; male and female, as well as old and young are affected. It is widely distributed around the world in the temperate zones3. A person is infected when a black-legged tick imbeds itse .....

.... they can run Linux on their computers(Windows can only run on Intel Based PCs).Digital Alpha systems are used by the huge companies.Linux has the capability of running on the Digital Alpha systems so it can reach the advanced users.Other computer system is Macintosh Power PC that is used by graphical designers,press companies and advertising companies, can be run with Linux. The others are Sun Sparc&Sun Ultra, Amiga, 3Com Palm Pilot which are rarely used. This capability of Linux provides a large user number and user kind that makes Linux more popular.(www.linux.org) Linux has a powerful security system.It is almost impossible to write a virus fo .....

.... C-46 transport, lost somewhere in the Mount Ranier area, a young Idahoan businessman named Kenneth Arnold spotted something that would change his life forever. Just north of his position flying at an altitude of 9,500 feet and an unprecedented airspeed of 1,700 mph he spotted nine circular aircraft flying in formation. According to his estimate the aircraft were approximately the size of a DC-4 airliner ( Jackson 4). This account was the first sighting to ever receive a great deal of media attention. This sighting gave birth to the phrase "flying Saucer" coined by a reporter named Bill Begrette. Although not the first UFO sight .....

.... more distant past. The air bubbles can be analysed for the relative abundance of carbon dioxide to estimate atmospheric carbon dioxide levels at times extending back 160 000 years. Through the ice sheet, we know that 160 000 years ago, carbon dioxide concentrations were about 180 ppm and have presently exceeded 350 ppm. 5) There are mainly 3 major sources of carbon dioxide presently and historically. They are industrial activity, land use change and cement plants. The carbon dioxide from industrial activity mainly comes from fossil fuel burning and is by far the most abundant of sources. The carbon dioxide from land use change comes mostly f .....
