... building up suddenly rupture, and then rebound.”(Associated 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 wa ...

... the center of the crystals. Minerals in each system share certain proportions and crystal form and many important optical properties. The six crystal systems are very important to a mineralogists and geologists; specification of the system is necessary in the description of each crystal system. Isometric This system comprises crystals with three axes, all perpendicular to one another and all have equal length. Tetragonal This system comprises crystals with three axes, all perpendicular to one another; but only two are equal in length. Orthorhombic This system comprises crystals with three mutually perpendicular axes, all of different lengths. Monocli ...

... business, and national security. They also believe that they will affect importers of oil and coal. Senator Christopher Dodd of Connecticut says that health care is at the worst risk right now. He says that, "As much as 80-90% of our doctors' offices are not compliant. 64% of hospitals still have serious problems with the Y2K issues," (Senate Y2K Report Wendy Griffith). The senate also believes that they will affect Medicare, power companies, banks, and stocks. People now believe that they must remove their money from the banks. This is true, but most of them are waiting until the end of the year to do this. If everyone goes to the bank simultaneously to remov ...

... she will have inherited two defective X chromosomes and herself will be a hemophiliac. If she is not affected and the gene is recessive, she is now classified as a carrier. In some cases, there is no previous record of hemophilia in the family. Male children who would be born with hemophilia would be the result of the mutation of the gene. There are two types of hemophilia: Hemophilia A and Hemophilia B. Hemophilia A, also known as "Classical Hemophilia" is caused by a factor Vlll deficiency. This is the most common form of hemophilia. The second type of hemophilia, is Hemophilia B, and is sometimes referred to as the "Christmas Disease." Hemophilia B is ca ...

... Western Australia grow to over 80 metres in height. Around Sydney Harbour, blackbutts once grew as big as a large lounge room Eucalypts seem to be able to grow anywhere. They are found springing out of large cracks in rocks, growing at the edge of sandy dunes in the full force of sea gales, and bent and twisted at the edge of the snow line in the Alps. They are also found in other parts of the world from Ethiopia to Ecuador, from California to Israel. Where eucalypts grow is determined by many environmental factors such as soil type, amount of water, wind direction, the direction the tree is facing and whether there is frost. THE IMPORTANCE OF THE EU ...

... was initiated. Perhaps the most dynamic chemical reaction of Cesium occurs when it is exposed to oxygen. This exposure causes oxides to form, where even the heat from oxidation is enough to melt and ignite this metal. Another major reaction of Cesium occurs with water and ice. Ice with a temperature as low as -177 degrees Fahrenheit can trigger a vigorous reaction. Because Cesium reacts so violently with organic compounds, it is considered the most reactive of Alkali metals. There are four principle compounds that make up Cesium’s structure: Cesium Chloride, Cesium Fluoride, Cesium Carbonate, and Cesium Sulfate. The most important compound is Chloride, which ...

... Service Provider. Because telephone technology is much older than the Internet, there have been limitations to how fast data can travel over existing copper telephone lines. Using an analog modem, data is translated from its digital form to an analog signal, to travel over the telephone lines. Once it gets to its destination, the data is converted back into its digital form. Line noise is a result of data being transmitted as an analog signal. The FCC imposed limitations, decades ago, to minimize the amount of line noise that was allowed. This law was imposed long before the PC ever existed. However, it directly affects how fast we can access the Inte ...

... and goddesses were based on the planets that were visible to the people of that time. Astrology was also popular in Babylon, Egypt, the Middle East, and China. Modern Astrology has changed as new planets have been discovered. Astrology is about the interaction between the planets, including the Sun and the Moon, and the Star Signs. It studies the mathmatical cycles on which these interactions are based. In some ways, the forces between the planets involved in Astrology can be simplified into one word : gravity. The Sun has the greatest gravity and, therefore, the strongest affect on Astrology, followed by the Moon and the other planets. Astrology can be best unders ...

... replenishes the sand. Beach formation begins as eroded continental material--sand, gravel, and cobble fragments--is washed to sea by streams and rivers. Two separate processes result in the deposit of this sand and sediment on the shore. Most sediment is suspended in sea water and transported along the coast by the longshore current, a stream of water flowing parallel to the beach that is created by the action of waves breaking at an angle to shore. Longshore transport can deliver up to a million cubic yards of sediment annually to a single beach. In the second process, sand deposited onshore by the longshore current is then oscillated by waves breaking onto and r ...

... mankind and should not be banned. Cloning is the Creation of another person that is an exact copy of another person (Clarke 1); this leaves too much to the imagination and leads to misunderstanding of the methods scientists use in cloning. In more clear terms, cloning is the process in which DNA of a female egg is replaced with different DNA from another cell. This process is referred to as the Nuclear Transfer or Nuclear Substitution. DNA molecules are the strings of protein that hold genetic coding. In this operation, the nucleus, which is the part of the cell that contains the DNA, are carefully removed from an unfertilized female egg then replaced with the DN ...
