... to cost $6-7 billion alone. At the end of 1993, total nuclear waste fund expenditures through the end of the year were nearly 3.7 billion. Very little of this money comes from individual investors. If a retrievable facility (one where the casks of spent fuel can be retrieved later) is built, this will be a good deal more. Other disposal types, such as sub- seabed and space disposal may prove to be cheaper at a later time. This is a cause for concern, but there are a greater amount of reasons to further and eventually finish the Yucca Mountain Project. One is the desert climate naturally occurring in the western United States. The weather is dry and warm and t ...

... and sellers are the number of households owning personal computers (over 33% in the U.S.) and the exponential growth of applications of the Internet, most notably the World Wide Web (WWW). With increased penetration of computers, particularly multi-media computers equipped with CD-ROM drives and modems, subscription-based services such as America Online (AOL), Prodigy, and Compuserve, where consumers are able to check airline flight schedules and make reservations, purchase a wide variety of products, and discuss product performance with other consumers, are becoming very popular. Households in Chicago and San Francisco can purchase groceries from home usi ...

... the fuel economy was better, and the tires were also much quieter. was the answer to the challenges of designing rubber hoses and belts for agricultural, industrial, and automotive equipment (DuPont). 49 is used in mainly body armor and making architectural structures stronger (Sci. & Inv. Enc., 1354). 49 is mainly made out of coal, corn, air, and water; making it rot and rust resistant. Compared to steel and concrete, 49's psi (pressure per square inch) is 525,000, steel's is 36,000, and concrete's is 3,000 (New Necessities). The blast suppression, or body armor, is strong enough to endure machine gun fire (up to .3 caliber), land mines, terroristic weap ...

... a node at the closed end. When the air reaches the open end, the reflected compression wave becomes a rarefaction. It bounces back through the tube to the closed end, where it is reflected. the wave has now completed a single cycle. It has passed through the tube four times making the closed tube, one fourth the length of a sound wave. By a continuous sound frequency, standing waves are produced in the tube. This creates a pure tone. We can use this knowledge of one fourth wavelength to create our own demonstration. It does not only have to be done using wind, but can also be demonstrated using tuning forks. If the frequency of the tuning forks is ...

... irrespective of the metal the electrodes were made of or the kind of gas in the tube. In 1909, RA Millikan, an American scientist, measured that charge. All electrons are found to be identical no matter their source or the method of liberating them from matter. From the values of e/m, and e, the mass of an electron was calculated to be .00055 amu. PROTON- Eugeen Goldstein used a Crookes tube with holes in the cathode, and observed that another kind of ray was emitted from the anode and passed through the holes. He discovered this in 1886. In 1889, William Wien showed these rays to be positively charged. The ratio of charge to mass was smaller than el ...

... and turning. These estimates are usually based on the number of serious cs, the definition of which varies considerably. Some doctors define cs as those who cannot sleep at all; other are willing to categorize cs as all those who merely complain about their sleep. The currently accepted definition, to become known as DIMS (Difficulty Initiating or Maintaining Sleep). Several surveys have tried to pin down the exact cause of sleep problems. Of 1,000 households, one third had someone with current problems and in 42 percent someone had suffered from sleep disorders at sometime. Some doctor's polls have been revealing yet somewhat disparate. In one survey, roug ...

... base pairing 3. The diameter of the helix is 2.0 nm and adjacent bases are separated by 0.34 nm and inclined at 360 relative to each other. This means that each complete turn of the double helix contains about 10 base pairs. 4. The amount of guanine is usually equal to that of cytosine. The monomers of RNA and DNA are called nucleotides. Each nucleotide has three parts: A Five Carbon or Pentose Sugar The sugar will be one of two very similar pentose rings. Ribo contain the sugar ribose. Deoxyribo contain the sugar deoxyribose. The only difference between these two sugars is that deoxyribose contains one oxygen atom less than ribose. Pentose sugars are essen ...

... thoughts, and loss of interest in usual activities. They feel like they’re worthless and hopeless. They also have negative thoughts towards the past and future. Many people go through guilt, crying, or having suicidal thoughts. Unlike a manic episode, the person has lack of energy, and either an appetite loss or gain. is a recurrent illness, so a person usually has more than one episode. These episodes can last from weeks to months. They occur whenever and have no certain pattern. Sometimes a stressful life event can trigger an episode, and sometimes they just happen. If a person has more than four episodes a year they are known as “rapid c ...

... bright stars according to the CONSTELLATIONS they are in. Thus, the brightest star in the Big Dipper (part of the constellation Ursa Major) is called alpha Ursa Majoris. Polaris, in the Little Dipper (Ursa Minor), is gamma (designated by the Greek lower-case letter gamma) Ursa Minoris, and Betelgeuse, in Orion, is gamma Orionis. VARIABLE STARS (those which periodically change in brightness) have lettered names, such as RR Lyrae in the constellation Lyra. Fainter stars are known by their numbers in a catalog; HD 12938 is the 12,938th star in the Henry Draper Catalogue. CHARACTERISTICS OF STARS Each star in the universe has its own position, motion, size, mass, ...

... which used were quadrant, armilla, and triquetrum. All furnish some measure of the position of the heavenly body. It took an endless amount of mathematical calculations to come up with the Copernicus' theory. He had to find out how fast the Earth spins around the Sun, and how far the Sun is. He also had to calculate the length of the orbit of the Earth. People use math in every walk of life. In our days everything is related to math, and Copernicus used his knowledge of mathematics to provide the human kind with an important discovery. Only a small amount of people are interested in Copernicus' work. If it wasn't for Copernicus' love of scientific t ...
