... (growth of the genetically altered Escherichia coli under controlled conditions). The chains were purified and later combined by chemical techniques to produce insulin structurally and chemically identical to pancreatic human insulin. (Hyde, 1984) As of 1986, human insulin began to be produced by a process which involves the enzymatic conversion of human insulin's biosynthetic precursor, human proinsulin. The genetic coding for human proinsulin is inserted into the special E. coli bacteria which are then grown in a fermentation process to produce human proinsulin. With genetic engineering, new proteins are synthesized. They can be introduced into plants or an ...

... of energy they emit. Since the mid 1900's radioactive wastes have been stored in different manners, but since several years new ways of disposing and storing these wastes have been developed so they may no longer be harmful. A very advantageous way of storing radioactive wastes is by a process called 'vitrification'. Vitrification is a semi-continuous process that enables the following operations to be carried out with the same equipment: evaporation of the waste solution mixed with the ------------------------------------------------------------ 1) borosilicate: any of several salts derived from both boric acid and silicic acid and found in ce ...

... air resistance pushes up as pulls down, which causes the object to slow down. When Galileo's experiment was repeated on the moon, the hammer and the feather hit the ground at the exact same time. This is due to the fact that the moon has no atmosphere. Therefore, air resistance doesn't exist on the moon. Also, the amount of air resistance on an object depends on the speed, size, shape, and density of the object. The larger the surface area of the object, the greater the amount of air resistance on it. This is why feathers, leaves, and sheets of paper fall more slowly than pennies, acorns, and crumpled balls of paper. There is another legend that states that wh ...

... was readily available. Being around big happy plants all the time helps people in the south happy by giving them something to take their mind off of life for a while. Garden Geraniums may reach the size of a bush in warm, dry climates (Garden Geranium 1). Again, the bright colored flowers make any bouquet of flowers complete. It is very hard to get any Geraniums to grow in short and cold growing seasons, like in the Pacific Northwest. It was very easy to grow and pick the beautiful flowers in the south. Wisteria is in the legume family of woody, climbing plants. The best know Wisteria are Chinese, but American are just as good. Most people use them for crawl ...



Global Economy And The Environment

... is one of the key issues that the policy makers and MNCUs should set a high priority on. This is because growth and development is strongly correlated with environmental degradation. Furthermore, it is fair to say that the MNCUs are more likely to have a more harmful environmental impact from growth and development, as opposed to the local corporations. This is because MNCUs may not be as knowledgeable as local corporations in resource utilization and land management. This also refers to the notion of Rthe locals know their land better than anybody elseS. The tropical rain forest of Brazil is a good example of this. The RindigenousS or the local peopl ...



Computers That Mimic The Human Mind

... then we must first look at the capabilities of the human mind. If one looks closely at the capabilities of the human mind and compares them to the most recent technological advances, then it would be obvious that computers and software are beginning to mimic even the most advanced mental states. In the future, computers will be able to do anything the human mind is capable of thus proving Eliminative Materialism to be a sound solution to the mind-body problem. Most of the day the human mind is taking in information, analyzing it, storing it accordingly, and recalling past knowledge to solve problems logically. This is similar to the life of any computer. Hum ...

... and overpopulation of humans that was the cause of the environmental problems that we have today. 2. Human Activity Causing the Problem The reason our Earth is getting hotter is that human activities are emitting too much carbon dioxide into the atmosphere. The radiation from the sun gets trapped in the bag of carbon dioxide that surrounds our earth. One main reason for the problem of global warming is the burning of fossil fuels. Fossil fuels are coal, oil and natural gases. We use these fuels to run factories, power plants, cars, trucks, buses, air conditioning and etc. The people of the earth are putting 5.5 billion tons of carbon, in the form of c ...

... have been around for multiple centuries and are cut down daily in a matter of hours in order to produce more buildings and houses in this already over-crowded world. If the rate at which we cut down trees is continued without any regulation, the forests will all be gone in ten years, so we should do mankind a favor and try to preserve what is left. If the old growth forests are gone, then they can never return because it takes over five generations to produce one and at the rate that the human population is increasing, there is not enough land to have a secure place for a new forest. If we realize that it is best for the human race to stop destroying the natural ...

... especially should recognize the many benefits from genetic engineering. They could end up with a cure a lot faster and find easier ways of getting treatment to healthier foods. From this kind of example, genetic engineering should be a known and accepted practice. It is a safe way to create good quality foods, create new lives, and cure diseases. In May of 1994, the Food and Drug Administration approved a genetically engineered tomato called “Flavr Savr”. Many people cringe at the thought of eating them. These tomatoes, though, are proven better and healthier even though they are slow ripening. The idea of altering a plant's traits seems radical and new, bu ...

... in their behavior. Manic-depressives, due to their spontaneous nature, are more likely to commit suicide than depressives. Manic depression involves alternating episodes of serious mania and depression. An affected person’s mood can swing from excessive highs (mania) to deep hopelessness (depression), usually with periods of normal mood in between. Some individuals may display mixed symptoms of both mania and depression at the same time, while others may have fewer symptoms of mania (also referred to as hypomania). The type severity, and duration of mood episodes may vary. Some individuals may experience excessive mania, or excessive depression, and som ...
