.... as much an addict as someone hooked on crack, cocaine, morphine or heroin. The folks that say they don't want to quit, because of the pleasure they derive from smoking, are not really speaking for themselves. It is their addiction speaking for them. It is that little addicted voice inside their minds rationalizing the addiction, because they know, it might hurt to quit. They know that there will be a sense of loss. They know that smoking is as much a part of their personality as being a happy person, or being a morning person, or liking to go to the movies. Smoking becomes a part of who and what you are, An addict. It amazes me the number of people who smoke .....

.... he made the first distinction between children who were cretins and what he referred to as "Mongoloids." Down based this unfortunate name on his notion that these children looked like people from Mongolia, who were thought then to have an arrested development. This ethnic insult came under fire in the 1960s from Asian genetic researchers, and the term was dropped from scientific use. Instead, the condition became "Down's syndrome." In the 1970s, an American revision of scientific terms changed it simply to "Down syndrome," while it still is called "Down's" in Europe. In the first part of the twentieth century, there was much speculation of the ca .....

.... is the degree measure from the horizontal that a wing is elevated or declined. When the angle of attack is between 1 and 20 degrees, the most lift is generated. To find the lift generated by a particular area of wing in a standard airfoil shape, a teardrop with the fat end facing forward, the equation L=Cl 1/2 (pV2)S. Cl is the lift coeficent, which is determined by the shape of the airfoil and the angle of attack. P stands for the air mass density, V for the velocity of the air passing over the wing, and S for the area of the wing when viewed from above or below. As the air flows over the wing producing lift, it grabs onto the wings surface and cause .....

.... measure the mass of the copper while in the vial. Remove approximately 0.35 g into a 250 mL beaker. check the balance and record the mass of the remaining mixture in the vial. In the laboratory hood, dissolve the copper with ~ 3 mL of nitric acid. Allow the beaker to remain under the hood until the fumes cease. The remaining solution should be blue. Bring the beaker back to the lab station and add ~ 10 mL of distilled water. Stir the mixture, all the while adding ~ 8 mL of 6M of NaOH to the beaker. Check with litmus paper to ensure that it is slightly basic. Fill the beaker with up to 100 mL mark with distilled water. Heat the solution and allow .....

.... 1 Although the general structure of all amino acids follows figure 1, the presence of a zwitterion is made possible due to the basic properties of the NH2 group and the acidic properties of the COOH group. The amine group (NH2) is Lewis base because it has a lone electron pair which makes it susceptible to a coordinate covalent bond with a hydrogen ion. Also, the carboxylic group is a Lewis acidic because it is able to donate a hydrogen ion (Kotz et al., 1996). Other forms of amino acids also exist. Amino acids may exists as acidic or basic salts. For example, if the glycine reacted with HCl, the resulting amino acid would be glycine hydrochlorid .....

.... testing is the material used to make blue jeans and is currently one of the world's most popular fabrics. It is fairly heavy and is made with a blue cotton warp and a white cotton filling (Groilers, 1996). The thermal underwear is duofold, with an outer layer made of 65% cotton, 25% wool, and 10% nylon, and an inner layer made of 100% cotton. It's the winter again and the weather is becoming colder. Each morning many people wonder what to wear to stay as warm as possible, but they aren't sure which material will keep them warmest. The experiment was chosen to see which clothing insulator retains the most heat. "Insulation is material that protects agai .....

.... he may return in the afterlife. The first sign that the end of natures yearly cycle, autumn, is approaching is when the leaves begin to change their color and whither. Even though they are changing color because they are dying, that thought is dismissed from the mind because of the beauty in that event which the eye beholds-with humans it should be the same thing. People should not feel sad seeing their elder loved ones change their colors and whither but rather rejoice from the knowledge that they lived a magnificent life and their death is merely the start of a new beginning. After all the leaves have fallen, and the ground is littered in seas of immense co .....

.... have emerged. A major influence in the development of what is now known as the computer were made by the United States military in the 1940's and 1950's. The needs of the military at the time required that a system be created that could aid in the aiming of ballistic military equipment. Today’s modern computers are undoubtedly the result of the United States military’s early developments and technological advancements in computing. Because of the military’s need for the computer earlier this century, great advancements have been, and will continue to be made in the way of computers and other technologies. Truly the first computers, or tools made with th .....
