... these biological processes slightly differ for eukaryotes and prokaryotes, they are the basic mechanisms for which proteins are formed in all living organisms. There are four main levels of a protein, which make up its native conformation. The 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, ...

... data structures. However, all have limitations - either in functionality or in terms of cost - and their strengths are almost inevitably outstripped by users' demands. During the past three years, data warehousing has emerged as one of the hottest trends in information technology for corporations seeking to utilise the massive amounts of data they are accumulating. Managers from all business disciplines want enterprise wide information access, as well as the ability to manipulate and analyse information that the company has gathered for a single purpose, to make more intelligent business decisions. Whet ...

... is increased by 0.4 percent each year because of the massive consumption of fossil fuels such as oil, coal, and natural gas. Another contributing factor is the the amount of forest logged, every second of the day the area of a football field in trees is cleared by either being logged or burnt. Two other deadly greenhouse gasses which are entering the atmosphere even faster than carbon dioxide are methane and chloroflourocarbons, although they are not as damaging in the long run. These increases are likely to affect worldwide temperatures dramatically. In 100 years time the average temperature for ...

... two million new cases reported this year in the U.S. The disease is . is a group of rapidly reproducing, undifferentiated cells in the area of the breast in women. The earliest changes occur in the epithelial cells of the terminal end buds (TEB) of the breast milk ductal system. While the outlining steps of are unknown, the cells in the breast trigger a reaction of cell reproduction. These new cancer cells form tumors. If cancer cells are active or are considered malign, the tumor grows at tremendous speeds, and may end up in metastasis. Metastasis is a complex process in which cells break away from their prim ...

... sometimes even a cardiac catheterization is done if the outcome is felt necessary to make management decisions. This is a complex area which requires careful judgment by physician and patient. is a manifestation of coronary artery disease, the same disease leading to heart attacks. Coronary artery diseas refers to those syndromes caused by blockage to the flow of blood in those arteries supplying the heart muscle itself, i.e., the coronary arteries. Like any other organ, the heart requires a steady flow of oxygen and nutrients to provide energy for rmovement, and to maintain the delicate balance of chemicals which ...

... to her. In 1968, she began to have telepathic experiences, which were initially very frightening. In 1980, she tried being regressed under hypnosis by Dr. Leo Sprinkle. During the sessions conducted by Dr. Sprinkle, she was unable to recall what her captors looked like, but did remember that technological implants had been made, including audio-visual implants. The UFO entities can see through her eyes and hear through her ears. She is aware of the continuous presence of what she calls her "live-in companion," who answers to the name of Hweig. Mrs. Kannenberg realizes that Hweig would b ...

... pulls the star’s material towards it’s center no longer has an opposing force to act against it. As a result the star collapses. A star that once had eight times as much matter as our sun and was 1,000,000 miles across, becomes a sphere only ten to fifteen miles across. As the star collapses, very small particles (called neutrinos) escape into space. After the star becomes a very small sphere, it explodes like a giant nuclear bomb and becomes a billion times as bright as our own sun. All kinds of matter and radiation are blasted into space. This matter and radiation travels through space at near ...

... characteristics that can be mapped such as continuous snow or deserts. One of the most popular classification systems is the Koppen Climate Classification system, which gives different climates three letters that describe that climate. The Koppen Climate Classification system is comparatively simple and is based on a triad of letter symbols. The first (capital) letter is the critical one; the A climates are humid and tropical; the B climates are very dry; the C climates are humid and mild; the D climates reflect increasing cold; and the E climates mark the polar areas. The first letter is follo ...

... and structure of communities. The processes of predation affect virtually every species to some degree or another. Predation can be defined as when members of one species eat (and/or kill) those of another species. The specific type of predation between wolves and large ungulates involves carnivores preying on herbivores. Predation can have many possible effects on the interrelations of populations. To draw any correlations between the effects of these predator-prey interactions requires studies of a long duration, and statistical analysis of large data sets representative of the populations as a whol ...

... a precise, sequential consideration of data, obtained by clinical observations, interrogation to obtain a detailed case of history, and palpation of the pulses. There are three main methods of diagnosis that are employed in the clinic: looking, asking and palpating, all of which contribute to a full and accurate diagnosis of the patient’s condition. By looking at the patient’s face, body and movements, the practitioner is already beginning to create a diagnosis. Another major diagnostic tool is the tongue. It is said that the state of the internal organs is reflected in the tongue, and the practitioner will ...
