.... standards”, you ask. The answer to this question lies in the history of UNIX; UNIX is a sort of subset of a much larger and more complex operating system called MULTICS. Both UNIX and MULTICS were developed decades ago for very large computers; only now, decades later are personal computers finally powerful enough to tackle these multitasking, multi-user systems with advanced features. Getting back to the crux of our first fact, LINUX looks like UNIX. LINUX is not officially UNIX simply because it was not written by the same programmers as was the .....

.... treat ringworm and many other skin infections. It was then limited because of the narrow margin between the benefits and its health risks. Thallium bromide-iodide crystals are still used as infrared detectors. Thallium sulphate used to be widely used as a pesticide and an ant killer. It was odorless and tasteless and worked well, but it was found to be too toxic. Thallium slats which burn with a bright green flame are used in flares and rockets. Thallium is the 60th most abundant element in the Earth’s crust. There are 3.6 parts of Thallium in every milli .....

.... were banned in '78 and a nation-wide toxic waste site cleanup program was developed in 1980. The EPA then evacuated Times Beach, Montana for dangerous levels of dioxin in soil, which was then criticized for its heavyhandedness and arrogance. Charges of mismanagement and undue political influence caused the head of the EPA to resign in '83. "The deputy director resigns because of charges of making a 'hit list' of employees to be hired, fired, or promoted because of political leanings. The former head of the toxic waste cleanup is found guilty of perjury and .....

.... with an initial energy of about 1 MeV will induce fission is rather low, but can be increased by a factor of hundreds when the neutron is slowed down through a series of elastic collisions with light nuclei such as hydrogen, deuterium, or carbon. This fact is the basis for the design of practical energy-producing fission reactors. In December 1942 at the University of Chicago, the Italian physicist Enrico Fermi succeeded in producing the first nuclear chain reaction. This was done with an arrangement of natural uranium lumps distributed within a large stack of p .....

.... of dilutions. The reactions will then be observed to see at which point a precipitate no longer occurs. Ksp will then be stated as a range of values at room temperature, and the precipitate test tubes will be heated until the precipitate is dissolved so that Ksp may be observed and determined at different levels. In this experiment various solutions of lead nitrate and potassium iodide were mixed at a number of different dilutions. Through the observation of the amount – or lack of precipitate formed in each dilution, the mathematical relationship b .....

.... main reason most countries use thermal versus the hydroelectric is because their countries don't have enough concentrated water to create enough energy to generate electricity. (World Book vol. 14, 586) Nuclear power plants generate only about eleven percent of the world's electricity. There are around 316 nuclear power plants in the world that create 213,000 megawatts of electricity. (INFOPEDIA) Radioactive, or nuclear, waste is the by-product of nuclear fission. Fission occurs when atoms' nucleus' split and cause a nuclear reaction. (General Informatio .....

.... to say how much water there is left in your well. It is also difficult to tell where exactly the source of recharge for your well is. Thus if an area near your well becomes polluted, the pollution may seep into the groundwater feeding your well. The purpose of this project is to explore the subject of groundwater, its place in the water cycle, how it seeps through the ground and how it accumulates in underground pockets called aquifers. The project will also examine the many uses of groundwater in agriculture as well as environmental problems that are presen .....
