.... the surface to bubble up in some places. Eventually, the weak spots of the crust break open from the pressure, and the gas shoots outward; this is referred to by astronomers as a jet. Dust that had been mixed in with the gas is also pushed out, and as more jets appear, a small gas and dust shell forms around the nucleus, and this is called the coma. The coma, also called the head, is a dense cloud of water, carbon dioxide and other gases and comes off of the nucleus. They can be several thousand kilometers in diameter, depending on the comet’s distance from the sun and the size of the nuc .....

.... of the bass remain the same nort and south. The spawn in the spring, when water temperatures begin to move past sixty degrees fahrenheit. The spring spawning urge in a bass is set off by both water temperature and photoperiod. Photoperiod is the proportion of the day in which the bass are exposed to sunlight. As the day light hours grow longer through the spring and early summer, so does the photoperiod. This process affects the temperature of different bodies of water in different ways. Small shallow ponds heat up much earlier in the year. As a result the bass will begin to spawn muc .....

.... into extraordinarily thin sheets. For example, one ounce of gold can be hammered into a 100 square foot sheet. Gold is the most reflective and least absorptive material of infrared (or heat) energy. High purity gold reflects up to 99% of infrared rays. Gold is also an excellent conductor of thermal energy or heat. Since many electronic processes create heat, gold is necessary to transfer heat away from delicate instruments. Gold alloy is the most tenacious and long-performing material available for protection of these temperatures. Geologists use the latest technology such as satellite .....

.... big-warfare program in the world, with 32,000 scientists working on it. Much of it had to do with genetic engineering. In one of the projects they took smallpox, which has otherwise disappeared from the world, and found a way to genetically introduce into it, without reducing its efficacy as smallpox, either Ebola virus or equine encephalitis viruses. Nobody seems to know what happened to those experimental viruses. A third example: we now have plants genetically engineered to produce plastic. The idea is that we will no longer need to depend so much on petroleum, or on the Middle .....

.... and; 3) How can faculty begin to integrate these technologies into their classrooms and research. Key words: teaching sociology, information technology, on-line teaching Introduction Information technology is quickly becoming the hub of efforts within the higher education community. Indeed, colleges and universities have demonstrated a fierce rush to amass technological tools, and are only now addressing the possibilities for adapting them to academic use. Ideally, new networked information technologies, such as the World Wide Web and E-mail will become fruitful pedagogical tool .....

.... the metabolism of melanin during prenatal development. This can be inherited by an dominant or recessive trait. In complete , there is lack of pigmentation in skin and hair, as well as in retinal and iris tissue; in incomplete , skin and hair may vary from pale to normal; in ocular , function may vary from norma to impaired. Impairments may involve the retina and iris. If a person has then they usually have somewhere between 20/70 and 20/200 visual. Ty-Neg or also called type 1A results from a genetic defect in an enzyme called tyrosinase. Tyrosinase helps the body to change the ami .....

.... but when in the stratosphere it binds to and destroys ozone. This is a cyclic process and therefor means that one chlorine can destroy many ozone molecules (Figure 1.2) During the winter in the Antarctic the circumpolar vortex, which is a strong westerly circulation around the continent, builds in the stratosphere. This phenomenon causes the interior of the stratosphere to be cut off and the temperatures drop below -800C. This results in thin clouds forming and that enables reactions with gases containing chlorine to take place. In the spring the sun returns and the chlorine in th .....

.... when you put it on snow and the snow melts it runs into a river or goes down to the ground water and pollutes it. The best way of handling of manure is to build a six month pit or harvester. That means that you can hold your livestock manure and all the runoff that is run into it for six months or more. To build a pit you must have a overview map that shows; "1. Farm buildings, yards surrounding area, homes, other buildings, lakes, ponds, streams, roads, and other prominent landmarks, with in about one-half mile, should be shown and feet .....

.... legends and unsubstantiated theories. The inuit believed that the northern lights were the spirits of dead relatives, dancing around in the sky, while the Vikings believed that they were caused by a fire on the edge of the world. In the fourteenth century, Aristotle described the auroras as jumping goats caused by the earth=s vapours being set on fire by meteors. Later on, in 1707, a Norwegian physicist claimed that they were caused by steam and smoke that escaped from a heat source beneath Greenland. It was not until the late 1950's that scientists finally discovered the true cause of .....

.... 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 ------------------------------------------------------------ 1) borosilicate: any of several salts derived from both boric acid and silicic acid and found in certain minerals such as tourmaline. additives necesary for the production of borosilicate glass, calcination and elaboration of the glass. These operations are carried out in a metallic pot that is heated in an induction furnace. .....
