.... fibre optics, is the channelled transmission of light through hair-thin glass fibres. The clear advantages of fibre optics are too often obscured by concerns that may have been valid during the pioneering days of fibre, but that have since been answered by technical advances. Fibre is fragile An optical fibre has greater tensile strength than copper or steel fibres of the same diameter. It is flexible, bends easily, and resists most corrosive elements that attack copper cable. Optical cables can withstand pulling forces of more than 150 pounds. Fibre is hard .....

.... the astronauts in the Columbia deployed two commercial communications satellites from November 11 to 16, 1982. Later memorable flights included the seventh, whose crew included the first U.S. woman astronaut, Sally K. Ride; the ninth mission, November 28-December 8, 1983, which carried the first of the European Space Agency's Spacelabs; the 11th mission, April 7-13, 1984, during which a satellite was retrieved, repaired, and redeployed; and the 14th mission, November 8-14, 1984, when two expensive malfunctioning satellites were retrieved and returned to e .....

.... do this, to the cytoplasm. In the cytoplasm there are free transfer RNA [tRNA] molecules which hve three protruding bases these sets of three on the tRNA are called anti-codons. Each tRNA molecule attracts different amino acids, of which there are around twenty, and they "stick" to the tRNA and depending on which tRNA molecule it is it wil attract a diferent amino-acid.On the RNA every three bases are called codons these are complementary to the anti-codons of the tRNA. For instance a codon of - GAA - would pair with the anti-codon- CUU -. In this fashion weak hy .....

.... emissions from electric power generators in three Canadian provinces. There are also some interesting questions and answers and facts are included also. This information was organized from various websites. It also contains information from a newspaper article about a new monitoring site for acid rain in Irish Cove located in Cape Breton, Nova Scotia. ACID RAIN The atmosphere, unpolluted, is the means of life on earth. It is a thin layer of gases which surrounds our planet. It is known that without the atmosphere our planet would be inhabitable, but we co .....

.... that technological implants had been made, including audio-visual implants. The UFO entities can see through her eyes and hear through her ears. She is aware of the continuous presence of what she calls her "live-in companion," who answers to the name of Hweig. Mrs. Kannenberg realizes that Hweig would be explained away by conventional scientists in terms of split personality or some other form of mental abberation. Although she does not agree with this interpretation of her situation, she does not claim to have any paranormal abilit .....

.... the increased price of water, or even the ever increasing occurrence of sinkholes, the evidence of a water shortage is everywhere. Since we need water to survive, and there are no alternatives to support life on this planet, we must find a way to keep up with our ever increasing water demand. This report presents the water shortage problem that is occurring in Florida. This report will familiarize you with the problem and explain the other uses currently being employed in Florida. This report also explains the procedure, as well as a recommendation including .....

.... were genetically identical, which sparked a fury of outcry all around the world. The technique of transferring a nucleus from a somatic cell into an egg cell of which the nucleus had been removed, called nuclear transplantation, is an extension of research that had been ongoing for over 40 years. Up until now, scientists thought that adult cells could not be “reprogrammed” to behave like a fertilized egg and create an embryo, but the evidence obtained by Dolly’s success prove otherwise. The issues of cloning have been around for a long time, starting with the p .....

.... 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 hydrochloride (see fig. 2). Glycine hydrochloride is an example of an acidic salt form of the amino acid. Likewise, if NaOH were added, the resulting amino acid would be sodium glycinate (see fig. 3), an example of a basic salt form. Fig. 2 Fig. 3 Due to t .....
