... still young in age has grown rapidly, spreading to countries world wide and connecting 50 million users. With its popularity, it is incumbent upon our society to recognize how the Internet works and to be aware of its advantages as well as disadvantages. While seemingly high tech the Internet concept is rather simple. Computers speak to one another and send information. This is accomplished by sending and receiving electronic impulse, and then decoding them into a message. In order to communicate with one another they are linked up in a network. They are then able to access information from thousands of other computers. The network acts like one large computer s ...
... genes into a common infectious organism, 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 Albert Jonsen. But the idea, he adds, raises a host of issues, "from the fantastic to the profound." When anesthesia was discovered in the 19th century, ther ...
... we also feel a responsibility to mothers and their babies to explore issues concerning the use of epidural anesthesia in labor issues that are seldom discussed prenatally. Several factors make the use of epidurals potentially hazardous. The Physician’s Desk Reference cautions that local anesthetics – the type used in epidurals – rapidly cross the placenta. When used for epidural blocks, anesthesia can cause varying degrees of maternal, fetal, and neonatal toxicity which can result in the following side effects: hypotension, urinary retention, fecal and urinary incontinence, paralysis of lower extremities, loss of feeling in the limbs, headach ...
... grabbed the guard’s AK-47 and killed seven more crew members on the way to the torpedo bay where he locked himself in. This suicidal teenager the stayed in the bay for twenty hours threatening to blow it up and potentially causing a “Floating Chernobyl”(Paddock-thestar.com). He talked to his mother and then he just killed himself. When scientists and nuclear activists got a hold of this story “it sent shivers through their spine” (Paddock-thestar.com). This was because one day they know that one suicidal teenager will actually have the guts to just blow himself up with all those nuclear warheads. Russian officials were q ...
... This is a question I hope to address in the following research. Self examinations are the most commonly used tests used for detecting breast cancer among women today. The self exam is a simple exam that women can perform on their own with a few simple steps. Another way of detecting breast cancer is with a mammography. This is an X-ray that scans in make up of the breast to show whether there are and tumors. This is the most effective type of detection to date. (Cancer Facts, Detection. National Cancer Institute) One disadvantage to using mammography is that with mammography, the x-ray picture sometimes detects substances in the breast that are not recog ...
... Acid Rain can dissolve limestone and chalk, and corrodes outdoor structures. Statues and monuments that are left unprotected can fall victim to the unpredjudiced destruction of acid rain. Acid Rain reacts to different types of soil and rocks in two ways. 1) Acid rain will dissolve alkaline rocks and soil, or will neutralize the alkalinity. 2) Acid rain will increase the acidicy of already acidic rocks and soil, such as granite, or the soil which results from corroded granite. Acidic chemicals, and alkaline chemicals react to each other by reducing the alkalinity or acidicy of each other. Which ever has the strongest pH level, usually will ne ...
... imagined , were one day projected onto the constellations which, in the Chaldean imagination, they resembled. This celestial menagerie has furthermore given the zodiac its name, for in greek, it means "route of animals." The sun enters the first zodiacal sign, Aries , and then continues its path through the remaining eleven signs. The twelve signs of the zodiac are: Aries, Taurus, Gemini, Cancer, Leo, Virgo, Libra, Scorpio, Sagittarius, Capricorn, Aquarius, and Pisces. The moon and the planets pass through the signs too, but obviously at different speeds from those of the sun. The moon, which is close to the earth, circles the zodiac in twenty-nine day ...
... alcohol presents,it is still in countless social cirles. Alcohol penetraes all ages, educational, occupational, and socioeconomical boundaries. Each year it is estimated that ten percent of all deaths are related to alcohol abuse. Am astonishing fifty percent of all major automobile accidents, and murders are associated with alcohol. On and on the statistics point to the enormous dangers of alcohol, yet it is a legalized drug. As bleak as this problems seems to be on society as a whole, it is also rueful for the poor soul who is alcohol dependent. The life span of the alcoholic is about ten years shorter than the non-drinker. The lifetime prevalence for in the ...
... inserted instructions for buildin g a metal-ion binding sight. They discovered where to put this slot by simulating the antibody on a large computer. The resulting product revealed an anti-fluorescein antibody which binds to metal ions. After physically inserting the genetic code in to E. coli. bacteria, the researchers had a large batch of a new compound which they named QM212. When copper was added to this new batch, it binded with the metal-ion binding sight, decreasing the fluorescent emissions. Applications: The human immune system already uses similar antibodies for similar tasks. Natural antibodies conform to the shape of foreign bodies a ...
... first level, primary structure, is just the basic order of all the amino acids. The amino acids are held together by strong peptide bonds. The next level of protein organization is the secondary structure. This is where the primary structure is repeated folded so that it takes up less space. There are two types of folding, the first of which is beta-pleated sheets, where the primary structure would resemble continuous spikes forming a horizontal strip. The second type of folding is an alpha helix, which goes vertically forming a wavy line. An alpha helix is in the same shape of one strand of DNA. These new formations are held together by hydrogen bonds. T ...
