Earthquakes
Words: 1173 / Pages: 5 .... Press 1993) The vibrations can range from barely noticeable to catastrophically destructive. Six kinds of shock waves are generated in the process. Two are classified as body waves-that is, they travel through the earth's interior-and the other four are surface waves. The waves are further differentiated by the kinds of motions they impart to rock particles. Primary or compressional waves (P waves) send particles oscillating back and forth in the same direction as the waves are traveling, whereas secondary or transverse shear waves (S waves) impart vibrations perpendicular to their direction of travel. P waves always travel at higher vel .....

God Guided Evolution
Words: 1329 / Pages: 5 .... studying numerous science authorities, logical deductions can be made that would help one form his own opinion on the matter. One might go so far to say as science and the Bible are God’s most basic forms of communication with the human; thus scientific deduction of the Bible should allow us to solve the mystery of man’s and the universe’s origins.
A very highly debated topic within the bigger argument is, “What started it all?” Creationists believe that God merely spoke all that we know into existence, but evolutionists prefer to believe a massive, random explosion spawned the cosmos. Obviously, a middle-grounder could find both preposte .....

Environment Report: Tidal Power In The Bay Of Fundy
Words: 1554 / Pages: 6 .... 3 main areas: the main Harbor,
Courtenay Bay and the Outer Harbor. These areas are influenced by the Bay of
Fundy tides and the currents of the St John River which flow out of the main
Habour into the Bay.
This section also experiences two high and two low tides each day (semi
- diurnal), with a tidal range varying from 15 to 18 feet, depending on the type
of tides. High - water heights vary from 22 to 28 feet and low - water heights
vary from 0 to 7 feet above chart data. Because of these semi - diurnal tides
and the action of the St John River, slack water in the Habour occurs at
approximately tides and not at high or low water as would be the .....

Nuclear Power
Words: 1824 / Pages: 7 .... radioactive wastes have been stored in different
manners, but since several years new ways of disposing 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

borosilicate: any of several salts derived from both boric acid and silicic
acid and found in certain minerals such as tourmaline. addi .....

DNA
Words: 1416 / Pages: 6 .... also in chloroplasts in plants, and mitochondria in plants and animals.
All DNA molecules contain a set of linked units called nucleotides. Each
nucleotide is composed of three things. The first is a sugar called deoxyribose.
Attached to one end of the sugar is a phosphate group, and at the other is one
of several nitrogenous bases. DNA contains four nitrogenous bases. The first two,
adenine and guanine, are double-ringed purine compounds. The others, cytosine
and thymine, are single-ringed pyrimidine compounds. (Miller, 141) Four types of
DNA nucleotides can be formed, depending on which nitrogenous base is involved.
The phosphate group of each n .....

Acid Rain 10
Words: 1747 / Pages: 7 .... industrial processes, such as the production of iron and steel, utility factories, and crude oil processing. In iron and steel production, the smelting of metal sulfate ore produces pure metal. This causes the release of sulfur dioxide. Sulfur dioxide can also be emitted into the atmosphere ny natural disasters or means. This ten percent of all sulfur dioxide emission comes from volcanoes, sea spray, plankton, and rotting vegetation.
The oxides of nitrogen are by-products of firing processes of extreme high temperatures, for example: automobiles, and utility plants; and in chemical industries, for example: fertilizer production, etc. Also, na .....

Iron
Words: 1056 / Pages: 4 .... 55.847, it's atomic number is 26, it's specific gravity is 7.86, it's
melting point is 1535 degrees Celsius, and it's boiling point is 3000 degrees
Celsius. It burns in oxygen forming ferrous oxide. When exposed to moist air,
iron becomes corroded, forming a reddish - brown, flaky, hydrated ferric oxide,
commonly known as rust. (Encarta, 1996)
Iron is formed in shallow seas. It comes out of the water and collects
on the sea floor. This creates an underwater deposit. This process occurs over
billions of years. Through plate movement the whole sea floor is eventually
moved up out of the water. Once out of the water, the iron has formed a lan .....

Dolphins
Words: 878 / Pages: 4 .... killer whale, which is also considered a
dolphin, can grow to be 30 feet long. The pilot whale is 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 t .....

Computer Education
Words: 271 / Pages: 1 .... 1950 in the U.S.. began in the middle of the 1950s with an organized body of knowledge. Also Japanese the teaching of computer science has been developed in the same period. During 1955 to 1959, some universities developed their own computers. They organized short courses.
Computer technology comes from the U.S. to Japan. Usually a technology is developed in the U.S.. After that, it comes to Japan so Japanese is late at all and most manuals are written in English so it is easy to lean computer for people who speak English; however, most Japanese people who live in Japan cannot understand English so they have to translate English to Japanese to un .....

Pulmonary Agents
Words: 2323 / Pages: 9 .... (the alveolar-capillary membrane); however, the precise mechanisms of toxicity remain an enigma. The U.S. produces over a billion pounds of phosgene (CG) per year for industrial uses; however, we do not stockpile this agent for military use.
Perfluoroisobutylene (PFIB) is a toxic pyrolysis product of tetrafluoroethylene polymers encountered in military materiel (e.g., Teflon7, found in the interior of many military vehicles). The oxides of nitrogen (NOxs) are components of blast weapons or may be toxic decomposition products. Smokes, e.g., HC, contain toxic compounds that cause the same effects as phosgene does. The remainder of this chapter wil .....
