... some good aspects of this genetic engineering, but they still seem pessimistic of the future of cloning in animals excluding humans. The first thing the article states is the Wall Street opportunities for the biotech field. Instead of phone calls from eager investors only phone calls from reporters were coming in asking about this market. I feel that now would be a great time to invest in biotechnical companies specializing in agricultural and medicinal cloning. This article says nothing about the great potentials of long term investment. Long term investment especially in the medicinal field is incredibly profitable. Just as in other controversial invest ...
... suggest that leptons and quarks may actually be the same object but in different states. Bosons, too, may be this same object but in still another state. The everyday world is made of molecules. Because molecules are so small, their existence was not easy to establish. Indirect evidence for molecules was strong during the second half of the 19th century, and the first explicit evidence was found when Brownian motion was correctly understood and studied in about 1906 by physicists Albert Einstein and Jean-Baptiste Perrin. There are many kinds of molecules, and it was clear that simplifying ideas were needed. The Russian chemist Dmitri Mendeleev argued that there ...
... sequence of cognitive deterioration is observed (Lezak, 1993). The mild stage begins with memory, attention, speed dependent activities, and abstract reasoning dysfunction. Also mild language impairments begin to surface. In the moderate stage, language deficits such as aphasia and apraxia become prominent. Dysfluency, paraphasias, and bizzare word combinations are common midstage speech defects. In the severe stage the patient is gradually reduced to a vegetative state. Speech becomes nonfluent, repetitive, and largely non-communicative. Auditory comprehension is exceedingly limited, with many patients displaying partial or complete mutism. Late in t ...
... and most predominantly, drug therapies. Drug therapy is the primary form of treatment implemented at the onset of schizophrenia. The drug clozapine is very effective for many patients who do not respond to initial drug treatment programs and treats both the positive and negative symptoms of schizophrenia (Advokat et al., 1999; Robinson et al., 1999). Moreover, a reduction in negative symptoms has also been noted to occur as individuals are treated with amisulpride and (Danion et al., 1999). The use of newer drugs to treat schizophrenia has produced fewer side effects in most patients. However, it has been found that although the use of risperidone to treat ...
... in it's pure form, but associated with other elements in rocks and minerals. An aluminosilicate such as felspar (KAlSi3O8) is the main constituent of many rocks such as granite, which is quartz and mica cemented together with felspar. These rocks are gradually weathered and broken down by the action of carbon-dioxide from the air dissolved in rainwater forming ‘kaolin'. This is further broken down to form other substances, ultimately resulting in the formation of Aluminium deposits. Where and how Aluminium is mined? Aluminium is never found in it's pure state until it has been refined. Aluminium is made when refining alumina, which is in turn found from the ...
... it is common to find families with several affected members. While such clustering'could also be due to shared non-inherited (environmental') factors,more convincing evidence has come from twin studies, as well as studies of ill individuals who were adopted away before the onset of illness. It is fair to say that even such studies do not suggest inherited factors as the sole causes. A more reasonable explanation is that there are individuals who have an inherited proneness to illness. Such individuals may fall ill, if in addition, they are exposed to noxious factors in the environment such as drugs. This model' is similar to that already proven in the ...
... was mentioned the first thing that came to people's minds were the bombings of Hiroshima or Nagasaki. No one ever considered the fact that plutonium could be used for more constructive purposes such as: sources of energy or to keep a person's heart beating. We did begin to produce more plutonium but the majority of the substance was used towards our nuclear weapons programs. Along with reactors, sometimes comes a meltdown which can cause harmful effects if it isn't controlled quickly enough. After such instances as the Hanford, Washington reactor meltdown and the accident in the U.S.S.R. at the Chernobyl site, no one wanted to hear about the use of plutoni ...
... mosquito does not feed. After about two days the pupa evolves into an adult mosquito. The new adult mosquito escapes from the pupae skin be splitting the skin open and resting at the water surface to allow its' body parts to harden. can complete the entire egg to adult cycle in 10 to 14 days, depending on the temperature, with shorter times during warmer periods. Some species can even reach the adult stage in as little as two to three days. Why Do We Need ? Mosquitoes are very abundant. Many of the eggs that mosquitoes lay in the water, and never become adults. They are eaten by fish, insects, frogs, toads and other amphibians. They are a major food source ...
... families with children form Asia, Africa, South America, Eastern and Mediterranean Europe (as these areas have a high number of people infected); drug users; and anyone in close contact with someone infected. This is not as scary as it seems, for you cannot contract the virus through sneezing, coughing, or holding hands. A surprising fact about hepatitis B, considering it is preventable, is that one in twenty people are or will be infected in their lifetime. There are one million people infected in the United States. More than 350 million people worldwide are chronic carriers of the virus. A chronic carrier is someone with the virus in their bloo ...
... but the number of radiation-caused deaths is still unknown. The same deadly radiation that was present in this explosion is also present in spent fuels. This presents special problems in the handling, storage, and disposal of the depleted uranium. When nuclear fuel is first loaded into a reactor, 238U and 235U are present. When in the reactor, the 235U is gradually depleted and gives rise to fission products, generally, cesium (137Cs) and strontium (90Sr). These waste materials are very unstable and have to undergo radioactive disintegration before they can be transformed into stable isotopes. Each radioactive isotope in this waste material decays at its ch ...
