... away. If you were to misplace a file in your office, it would probably be hard to find it, whereas if you lost a file on a computer you could use the find utility in Microsoft Windows 95, 98 or 2000 (by pressing the button and F at the same time) and the file would be found in a few seconds. On a computer you could automatically put the files in alphabetical order by whatever- name, GP, date of birth e.t.c. However, in an office cabinet it really would not be easy at all to put and keep the files in some sort of alphabetical sequence. Currently the database is pen-and-paper based, which may be cost effective but ...

... years ago. Burning fossil fuels has other downfalls, too. All the burning that is required to turn the turbines releases much sulfur, nitrogen gases, and other pollutants into the atmosphere. The cleanest, cheapest, and least polluting power plant of the two types is the hydroelectric power plant. The 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 ...

... of these nuclear wastes? Scientist have thought of several methods to dispose the nuclear by- products. They tried to chemically treat the waste and reuse it, but "that would cost a fortune". They thought of launching the waste into outer space but it too will cost a fortune. They tried to dump barrels filled with nuclear waste into the ocean but they started leaking. As you can see, there is a great need for a nuclear waste disposal site. These sites may sound frightening, but it may be the only way for us to dispose the devastation we had longed to create. In 1986, the decision for a nuclear waste depositary ...

... in the transmutation of metals. To this name the Arabs affixed the article `al', thus giving al-khemeia, or alchemy. HISTORY OF ALCHEMY: From an early period the Egyptians possessed the reputation of being skillful workers in metals and, according to Greek writers, they were conversant with their transmutation, employing quicksilver in the process of separating gold and silver from the native matrix. The resulting oxide was supposed to possess marvelous powers, and it was thought that there resided within in the individualities of the various metals, that in it their various substances were incorporated. Th ...

... operating systems already at hand can still be used throughout the network without conflicting with one another. Quick access and easy programming is also another consideration that is made when considering this type of network. Intranets have just started to be implemented throughout the world and already a big change is being noticed. Companies are keeping track of all of their important information on web sites, which are restricted to users, unless they have the security code to access them. Thanks to Internet technology, companies and other types of organizations are able to keep all of their information organ ...

... ivory. Elephant ivory is no longer at the biggest risk for poaching; hippo ivory is. Eastern Zaire once had one of the largest hippo populations in the world, around 23,000 hippos. According to a count done in 1994, this number has now dropped to 11,000. The 1989 ban on elephant ivory is the main cause attributed to the exponential rise to hippo ivory trade. "European and African activists are petitioning advocacy groups, including last week's annual Convention on International Trade in Endangered Species in Florida, for a ban on hippo poaching. But they say they're a long way from putting an end ...

... can be found when produced artificially in a laboratory. Discovery of the element was first claimed in 1957 by scientific groups in the United States, Great Britain, and Sweden, but the first confirmed discovery of a nobelium isotope was by a team of scientists at the Lawrence Radiation Laboratory in Berkeley, California and that took place in 1958. The isotope was created by bombarding curium isotopes with carbon ions. Chemically, the properties of nobelium are unknown, but because it is an actinide, its properties should resemble those of the rare earth elements. Isotopes with mass numbers from 250 to ...

... those in between are at the mercy of these microorganisms, which come in many forms - viruses, bacteria, fungi and parasites. The most dangerous of these forms is the virus. Some viruses, such as the common flu, are considered to have a fairly detrimental capacity. The flu can incapacitate a human for several weeks with various symptoms such as bodily soreness, fever, bronchial complications, and even pneumonia. But while these conditions can be painful and frightening, we are usually confident that proper medication and rest will take care of the matter. However there is a much more severe and indiscriminate tyran ...

... As a result of these risks, all special effects are regulated at the federal, state and local level. In general, all are explosives, but not all explosives are . Class A explosives (high explosives) are materials like dynamite and Primacord which may detonate even if unconfined. Pyrotechnic special effects materials are Class B explosives. They will burn, but not explode unless confined. Examples are black powder and pellet powder, safety fuses, igniters, igniter cord, fuse lighters, Class B special fireworks, and Class B composite solids propellants. Class C explosives are common fireworks. Note t ...

... There are distinctive patches of white on underside of the flukes). These markings are unique to each individual whale, like a fingerprint. The humpback's skin is freqently scarred and may have patches covered with diatoms. Humpback whales have 14-35 throat grooves that run from the chin to the navel. These grooves allow their throat to expand during the huge intake of water during filter feeding. They have small, round bumps on the front of the head edging the jaws. Humpbacks have huge, mottled white flippers with rough edges that are up to one-third of its body length; these are the largest flippers of any ...
