.... attempt to escape from the house when it was given the opportunity during the first four days. As the days progressed, it's total number of escapes decreased. This could be attributed to the fact that every time it found it's way outside, it was immediately picked up and returned to it's proper location. This is a perfect example of using the untraining technique of "negative reinforcement". Even thought the intent was to protect the cat from the harsh threats that awaited it in the real world, it was effective in reducing the number of escapes. After data collection was completed for the four days of observation, a progra .....

.... It does not involve adding anything to the water that is not already there, since virtually all sources of drinking water in the United States contain some fluoride. Fluoridation is a form of nutritional supplementation that is not unlike the addition of vitamins to milk, breads and fruit drinks; iodine to table salt; and both vitamins and minerals to breakfast cereals, grains and pastas. The protection of fluoridation reaches community members in their homes, at work and at school -- simply by drinking the water. The only requirements for the implementation of fluoridation are the presence of a treatable centralized water supply .....

.... even through the night the rays stay in and heat the air. The greenhouse is also called a "HOT HOUSE" because it gets so hot. The greenhouse effect is caused by gases such as carbon monoxide, carbon dioxide, and nitrogen escaping into the atmosphere. These gases get trapped in the ozone layer and do not let the suns rays escape very easily. This causes the earth to warm up. This warming can cause droughts, and this would really affect the farmers. This heating up will cause the plants and animals would die. .....

.... hydrated ions, for example H3O+, but more commonly they are released from ionisable hydroxyl groups (R-OH) where the O-H bond is broken to produce R-O- and H+. When the reactant receives protons from an acid it undergoes a conformational change, (change in shape and configuration), and becomes a reactive intermediate. The intermediate can then either become an isomer by returning a proton to the catalyst, or it may undergo a further reaction and form a completely new molecule. Up until the mid - 1960's silica-alumina gels were used to catalyse the cracking of hydrocarbons. This form of cracking is where the large molecul .....

.... coal became widely used for heating, cooking and industrial processes. Air pollution during the Industrial revolution was far worse than anything seen today. Apart from the smoke and fumes obscuring visibility, they also caused major health problems to the inhabitants of the industrial areas reducing life expectancies, predominantly with respiratory diseases. The simultaneous development of the internal combustion engine, well drilling technology and the capacity to refine crude oil into gasoline and other liquid fuels (B. Nebel et al 1995) in the late 1880’s, produced an alternative to steam power. Air pollution was g .....

.... All radio waves fall within a frequency range of 3 kilohertz, or 3000 cycles per second to 30 gigahertz. Within the range of frequencies, radio waves are further divided into two groups or bands such as very low frequency ( VLF 10-30 kHz ), low frequency (LF 30-300 KHz), medium frequency ( MF 300-3000 KHz), high frequency ( HF 3-30 MHZ) and very high frequency ( VHF 30-300MHZ). Amplitude modulation is the oldest method of transmitting voice and music through the airwaves is by amplitude modulation. This is accomplished by combining a sound wave from a microphone, tape, record, or CD with a "carrier" radio wave. The result : .....

.... adding or extracting heat from the gas or the surrounding system"(Vance 26). At the same time Pictet used the "Joule-Thompson Effect," a thermodynamic process that states that the "temperature of a fluid is reduced in a process involving expansion below a certain temperature and pressure"(McClintock 4). After Cailletet and Pictet, a third method, known as cascading, was developed by Karol S. Olszewski and Zygmut von Wroblewski in Poland. At this point in history Oxygen was now able to be liquefied at 90 K, then soon after liquid Nitrogen was obtained at 77 K, and because of these advancements scientist all over the world began comp .....

.... complications develop. Doctors estimate that, in women, one third of the s result in PID (Pelvic Inflammatory Disease). Often these infections are not diagnosed until PID or other complications develop. In men, rarely, s may lead to pain or swelling in the scrotal area, which is a sign of epididymitis, an inflammation of a part of the male reproductive system located in the testicles. Left untreated, this condition, like PID in women, can cause infertility. Chlamydia can cause proctitis (inflamed rectum) and conjunctivitis (inflammation of the lining of the eye). The bacteria also have been found in the throat as a result of or .....

.... had, and believe me, he has had many. The point is, APBT get a bad name because of the people who own them. In doing research for this paper I have become deeply fascinated with this breed and actually understand a great deal more about the APBT than the average person. But to understand more about the APBT, you must understand its history and its impact on society. The (APBT) is a descendent of the original English bull-baiting Bulldog and has historically been bred with working/performance goals in mind ( Stahlkuppe p.7). The challenge of describing the APBT invites a long sequence of superlatives. The APBT is a supremely at .....

.... reason these are causing such a commotion is the damage they cause to living things on Earth. When the ozone depletes, it causes more ultraviolet (UV) rays to hit the Earth's surface than are healthy (Singer and Crandall npg). UV rays affect the DNA of every living cell, altering the protein make-up of that cell (Goldfarb 288). Most importantly it affects "microscopic photoplankton" which rest at the bottom of the food chain, placing us in extreme danger (Goldfarb 288). Henry Lee, leading researcher on ozone depletion for the Environmental Protection Agency (EPA), says that UV rays will only have a slight effect on oceans .....
