... and millions of dollars in property damage, in the United States alone. It is difficult to obtain accurate statistics on lightning injuries and fatalities since a systematic compilation of information on lightning casualties does not exist. Many case histories show heart damage. Inflated lungs and brain damage have also been observed from lightning fatalities. Loss of consciousness, amnesia, paralysis and burns are reported by many who have survived. Deaths and injuries to livestock and other animals, thousands of forest and brush fires, as well as millions of dollars in damage to buildings, communications systems, ...

... contain compounds of magnesium in nature. Magnesium hydroxide (milk of magnesia) and magnesium sulfate (Epson salt) are well known. Milk of magnesia is used in medicine as a laxative. Magnesium is also used in artificial limbs, vacuum cleaners, snow skis, wheelbarrows, and lawn mowers. In 975AD calcium was useful for setting broken bones. There have been many uses for calcium over the years, but calcium has not been available on a large scale until the twentieth century. Calcium is a metallic element, which is fifth in abundance in the Earth’s crust. It is essential for forming leaves, bones, shells, and Po ...

... a large re-emergence in the southwestern United States and Mexico due to the arid climates in those areas. Cases have been spread all over the western U.S. with even a few in the east, but nearly half of the cases to date have been in the Four Corners area. In a dry area, the disease’s incubation is somewhat longer, making the chances of contracting it somewhat higher. In places such as woodpiles and sheds where there is little air circulation to move off the virus, it can linger for a sizeable duration of time. The best method of fighting the hanta virus is prevention. By controlling the rodent popula ...

... The force that resist motion between two surfaces that are touching each other. What do we use machines for? Machines are used for many things. Machines are used in everyday life just to make things easier. You use many machines in a day that you might take for granted. For example a simple ordinary broom is a machine. It is a form of a lever. Our country or world would never be this evolved if it wasn't for machine. Almost every thing we do has a machine involved. We use machines to manufacture goods, for transportation, ect. In the W=F*d equation the trade of between force and distance is as you use ...

... for a wider screen display, like those screens in movie theaters, and a sharper picture. What causes this perk is the fact that digital signals have a higher bit rate. This allows for more bits to be transmitted into the TV (cable, antenna, or satellite). The more bits a TV can transmit, the better the picture or screen resolution. The digital TV signal can carry as many as 19.4 megabits of data, which means a broadcaster can mix multiple programs of varying bit sizes onto a single channel. Say you’re watching a football game, since one camera view only uses up so many bits, you can select a different camera ...

... public has had some type of understanding about the power of plutonium and the devastating properties it possesses. After WWII, Americans started to think about what the atomic bomb could do to the United States and it's people. When ever plutonium was mentioned the first thing that came to people's minds were the bombings of Hiroshima or Nagasaki. No one ever considered the fact that plutonium could be used for more constructive purposes such as: sources of energy or to keep a person's heart beating. We did begin to produce more plutonium but the majority of the substance was used towards our nuclear weapons ...

... including molluscs, sponges, and worms, help shape reefs, but hard corals and various algae are the major architects. In effect, the corals build limestone, because their skeletons are made of Calcium Carbonate. The skeletons deposited by these corals and other organisms accumulate, along with sand and other debris, to form the backbone of the reef. Over tens of thousands of years, chemical and mechanical changes turn the reef into true rock. The body of a coral animal consists of a polyp, which is the living portion of the coral. A polyp is a hollow, cylindrical structure attached at one end to a surface, the ot ...

... "Recommendation for Recycling Water in a Florida Pilot Plant" The water shortage problem has affected all of us in one way or another. Either through the mandatory restrictions or the increased price of water, or even the ever increasing occurrence of sinkholes, the evidence of a water shortage is everywhere. Since we need water to survive, and there are no alternatives to support life on this planet, we must find a way to keep up with our ever increasing water demand. This report presents the wa ...

... and to grow will be provided for in most instances by a man made lighting system. Many different varieties of plants can be grown using the hydroponic technique. Some examples are lettuce, herbs and tomatoes, as well as seasonal flowering plant species. The use of hydroponics in gardening as well as large scale crop growth can enable the grower to produce many types of plants out of their normal growing season. Another attraction and use for hydroponic growing methods is that a person can have a garden in small spaces such as an apartment. In addition a good source of natural sunlight is not required be ...

... man of his own time. He made contributions to science, mathematics, and religious philosophy. Pascal was born on June 19, 1623 in Clermont-Ferrand of central France. His father was a highly placed civil official and everyone expected Pascal to follow in his footsteps. But Pascal proved to be a child prodigy. At the age of twelve, he figured out the proposition of Euclidean geometry with no help. At the age of seventeen, he wrote an essay on conic sections which contained a theorum that was named after him. Pascal also invented many things. He constructed the first digital calculating system for his fathe ...
