.... later became a classic. These books included an improved version of the periodic table. Sir Joseph Thomson, another important person in the development of the atomic theory, was born in 1906. Thomson won the Nobel Prize in physics (1906) for his work in the conduction of electricty through gases. He discovered the electron by using cathode rays. An electron is the smallest particle of an atom, the charge on an electron is negative. Ernest Rutherford, who was born in 1871 identified the three main components of radioactivity: alpha, beta, and gamma particles. Rad .....

.... Micheal J. Smith, a professor at the University of Wisconsin-Madison explains that knowledge can be used as a weapon or as a tool (DeTienne 462). For instance monitoring abuse can be found in the in the situation of airline agents. The agents discovered that by keeping customers on hold while finishing their work they could gain an extra 5-minute break (De Tienne 462). In the future these evasions of work will be stopped and for this reason "employee's who are accustomed to evading the monitoring system may no longer be able to tolerate it" (De Tienne 463). These types .....

.... same year, researchers in Pennsylvania cloned a live frog. The technique used was known as embryo twinning, or causing the embryo to split apart. It is much easier to clone with embryonic cells. Much later, mammals such as sheep were cloned using this process. (Nash 64) In 1970, John Gurdon repeated the procedure suggested by Hans Spemann. This time, the experiment yielded partial success. The tadpoles were born alive, but they died when they began to feed. He showed that transplanted nuclei reverted to an embryonic state. In the early 1980's, there was some controve .....

.... just like being there in person. in no way takes the place of face to face, but it does offer the convenience of a different means of communication. Videoconferencing is a type of conferencing in which video cameras and microphones capture sight and sound for transmission over a communications network. Videoconferencing makes it possible to conduct meetings with participation of groups who are hundreds and thousands of miles apart (Senn, 1998). As Joseph Jesson an information technology consultant at Amoco in Chicago put it the notion of was highlighted at the 1964 Worlds .....

.... structures. On average, acid rain is about nine times more acidic than rain water, and has been recorded as low as 2.5 on the pH scale (forty times more acidic than water.) Acid deposition kill fish, soil bacteria, and as well as aquatic and terrestrial plants. the acid also drain the soil of essential nutrients such as aluminum and releases them into bodies of water such as streams, lakes, and ponds. These bodies of water develop highly concentrated levels of these nutrients which can really harm the aquatic life forms in that area Those areas without any alkaline metal depos .....

.... genital . This is because there are very often no symptoms that go along with the virus. This is not always the case though and when symptoms do occur they are often seen as a cluster of blister sores, usually on the vagina, vulva, cervix, penis, or anus. For genital , symptoms may last several weeks, go away but only to return again weeks, months, or even years later. Symptoms may also include pain in the infected area, itching, burning feeling if urine flows over sores, and possibly an inability to urinate if severely swollen from many sores. Very severe outbreaks may h .....

.... most common in the atmosphere of the earth. It is also found in the earth’s crust. Sir Walter Ramsey and Morris W. Travers discovered it in 1898. Its uses include electric signs, lamps, and lasers. Argon is the most abundant and most used noble on earth. Sir Walter Ramsey discovered it by Lord Rayleigh and in 1894. Argon makes up about 1.2 % of the earths atmosphere. It is found naturally in rock and in the air. It is used for electric light bulbs and fluorescent tubes. It is also used a lot in industry. Krypton a very rare noble was discovered by Sir Walter Ramsey and by .....

.... movements also show paraheliotropic response as well. Paraheliotropism minimizes water loss by reducing the amount of light absorbed by the leaves; the leaves orient themselves parallel to the sun’s rays. Plants that exhibit paraheliotropic behavior usually do so at midday, when the sun’s rays are perpendicular to the ground. This reorientation takes place only in leaves of plants that are capable of nastic light-driven movements, such as the trifoliate leaf of Erythrina spp. (Herbert 1984). However, this phenomenon has been observed in other legume spe .....
