Cloning 7
.... such as the
influenza virus, could be hazardous.
We have come to believe that all human beings are equal; but even more
firmly, we are taught to believe each one of us is unique. Is that
idea undercut by cloning? That is, if you can deliberately make any
number of copies of an individual, is each one special? How special
can clones feel, knowing they were replicated like smile buttons. "We
aren't just our genes, we're a whole collection of our experiences,"
says Alb .....

Cloning 8
.... discourse and the public policy with respect to genetics must develop simultaneously. Human genetic material is routinely patented. In July 1990, the California Supreme Court ruled that a patient whose diseased spleen had been used to produce patented cell lines had no right to the millions of dollars potentially resulting from the sale of pharmaceutical products derived from his spleen. By September 4, 1993, the National Institutes of Health had filed for patents on 6,122 gene fragments. Although .....

Clubfoot
.... that same century, a mechanical device resembling a turnbuckle was used to help stretch the tendons. By this time clubfoot was pretty well known around the world, using the typical stretching and splinting methods. In the 1800’s plaster of paris was first introduced, and later that same century, the introduction of aseptic technique and anasthesia diminished, but not eliminated infection. As the 70’s and 80’s rolled around, other more reliable methods were depended upon. These new methods were less .....

Colorado River
.... a reliable or accessible water source, and timber for building was difficult to find. There was a lack of land that could be irrigated easily. By the turn of the century, most present day cities and towns were already established. Trails, roads, and railroads linked several areas with neighboring regions. Although the Colorado River drainage system was still not integrated. In the mid 1900’s many dams had been built to harness and use the water. A new phase of development occurred at the end of the s .....

Comets
.... the head of the comet and in the opposite direction from the sun. According to Charles A. Schweighauser in his book, entitled Astronomy from A to Z: A Dictionary of Celestial Objects and Ideas, he states that we see comet heads and tails because they not only reflect sunlight, but they also fluoresce—give off their own light—when comets are near the sun. The tails from the comet may be up to 150 million kilometers long each or together.
Comets have a predictable orbit. There are one thousand comets .....

Computer Aided Drafting And Design
.... clumsy, elaborate machines which needed lots of human intervention to one program on a floppy disk. When the power of computers increased, so did the possibilities of CADD.
Images on CADD systems are drawn with the aid of a keyboard, mouse, or tracking ball. One selects the starting point of a line, the ending point, and the line is drawn. A scale at the bottom of the screen tells how long the line will be. On some CADD systems, the computer itself can measure how long the line will be while the .....

Computer Illiteracy
.... assigns the students to send in all assignments by e-mail? Eventually, they will have to learn the basics of e-mail which, in turn, reveals even more problems with being computer illiterate. For an essay, the teacher requires that they go to the library to do research. The computer illiterate happily walks into the library to do their research. Imagine their surprise when they find out that the main tool of research is one of those darn computers. The poor illiterates stare blankly at a comput .....

Computer Viruses

Some damaged files cannot be repaired and must be replaced with uninfected archive files. The table below outlines some techniques used to protect computer systems.

.... California. Fossils have been found as far east as Texas, Florida, and New York. More recently, however, they were confined to a horseshoe-shaped area north of Los Angeles.
For years, no one knew precisely how many California condors existed, although they have been considered to be a declining species since the 1890s. One estimate put their number at 100 in the early 1940s. Another indicated there were 50 to 60 in the early 1960s. By the late 1970s, the estimate had dropped to 25 to 30 birds.

Coral Reefs And Bleaching Phenomenon
.... incoming waves. This is vital to maintaining the white sandy beaches that drive the tourist motivated economies in tropical regions. An example of the value of coral reefs in this regard is illustrated by Jon Luoma in his article “Reef Madness”. Luoma explains that after a land-reclamation project that destroyed a reef in the Maldives, the government had to spend more than $12 million to build an artificial seawall that served the same purpose(24).
As with all diverse ecosystems, the coral reef mu .....

The IEEE 802.14 Working Group is a committee of engineers representing the vendor community that has developed a specification for data over cable networking. The group, which was formed in the early 90's, had intended to develop a specification that would be rec .....

Caffeine
.... Where caffeine lifts your spirits, when it wears off there can be bouts of depression. If drank too close to bedtime, caffeine can disrupt your sleep. You can get the shakes from caffeine.
Recent studies have failed to find any relationship between caffeine and strokes or increased risk of heart attack. There is no evidence that caffeine causes cancer, elevated cholesterol or high blood pressure.
You can have caffeine, but in moderation. A maximum of 350 mg of caffeine a day is .....

Cancer 2
.... information, stored in a coded form DNA, is carried out of the nucleus by RNA and then translated into proteins by ribosomes. 70% of oncogenes are located in the weak points of the chromosomes-hereditary regions where the DNA molecule may break or its portions may be rearranged into new combinations. Actually most of the times, the nucleus and the DNA are constantly exposed to substances that may alter the genes. But these alterations are almost always prepared by intricate mechanism with the function of .....

Cancer 3
.... swelling of the joints. The most common form of arthritis is osteoarthritis, which is also known as degenerative joint disease because it is characterized by joint degeneration and loss of cartilage. Cartilage is the shock absorbing material between joints. The weight-bearing joints such as the knees, hips, and spine, as well as the hands, are the joints most often affected by osteoarthritis. These joints are under much greater stress because of additional weight and continuous use (lifting, sports, suppo .....
