.... serious chest injuries. Unfortunately for about 100 people in the past decade, their lives were saved at the expense of suffering a less severe injury caused by the air bag itself. However, when proper air bag safety is applied in conjunction of wearing a seat belt properly, most injuries and deaths caused by motor vehicle crashes are minimized or even prevented all together. Air bags are designed specifically to cushion occupants as they move forward in a front-end crash, keeping the head, neck, and chest from hitting the steering wheel or dashboard. In order to perform well, air bags deploy quickly and forcefully, with th .....

.... quite strange and hardly fulfilled their purpose of actually propelling the balloon. The basic propeller had evolved from the simple concepts of da Vinci, and was slowly becoming an effective means of aerial propulsion. To reach the next plateau of flight an increased knowledge of the propeller would be needed, and the mysteries of the propeller and mechanical power would need to be solved. These substantial tasks remained for aviation's pioneers to tackle during the 19th century. Throughout the 19th century, aviation pioneers explored and tinkered with the concepts of flight to design a viable airship. Some pioneers tried to tra .....

.... aging. As these diseases are conquered, far more people will live to their full potential life span and remain active and healthy for life. A lot is known about the diseases that affect people and cause death. Much less is known about real aging because it involves fundamental cell processes that are quite complex. However, this mystery of life is being unraveled and will offer opportunities in the future that were once considered to be only possible in science fiction. It is hard to improve on the advice given by Seneca (4 B.C. -65 A.D.) to eat moderate amounts of well-balanced foods, get plenty of fresh air, exercise, and li .....

.... placed in a extremely low salt diet, or later when salt was introduced, Of the hypertensive subjects, half of those on the low salt diet did experience a drop in blood pressure, which returned to its previous leel when salt was introduced. Of course, these are other researcherswhgich tend to support the findings. A small Indiana study showed that when normal individuals took large amount of salt, the bolld pressure did not consistenly rise into the hypertensive range. Also, study in Israel showed that a low-calorie diet could reduce blood pressure without changing salt consumption. After viewing research statistics, w .....

.... (Bartow 1) The second type of coal is Bituminous or soft coal. It's the most plentiful type of coal in the States, and is mainly found in the eastern and middle part of the North American continent. Bituminous coal is primary used to generate electricity, and has a carbon content of 45 to 86 percent and a heat value of 10,500 to 15,000 Btu's. Sub-bituminous coal rank just below bituminous coal with 35 to 45 percent carbon content. The heat value of Sub-bituminous coal is between 8,300 and 13,000 Btu's per pound. It can be found in the western parts of the states. Lignite the lowest carbon content then the others "it usually .....

.... are changing the world as we know it, and they offer an exciting new way of working. The news represented a complete turnaround for the corporate giant. Microsoft Chairperson, Bill Gates publicly announced his company's new connection to the Internet. The announcement rang through the nation. Gates has consistently ignored the Internet in favor of desktop computing. So, with Microsoft's approval, computers kicked into even higher gear (Gates, 72). The pace of innovation continues to astonish even those involved from the start. If one wants to find enthusiasm, intellect, hard work, and imagination; then computers is t .....

.... its compact beta-can structure. Biochemists now frequently exploit GFP’s unique structural and physical characteristics to visualize various cellular activities. One such application of GFP is to understand the role of a hormone, T3, in the translocation of thyroid hormone nuclear receptors (TRs).* In this project, GFP was fused to the human TR subtype b1 protein and the protein’s intracellular movement was visually tracked in live cells in the presence or absence of the T3 hormone. The prevalent hypothesis of this experiment was that T3 is essential in directing TR proteins to the nucleus of the cell where the proteins bin .....

.... theories is that another star once passed close to the Sun, and tidal perturbations between the two stars drew out filaments of gas from which the planets condensed. Theories of this type encounter enormous difficulties in trying to account for modern information about the solar system, and they have generally been discarded. By contrast, monistic theories envisage a disk of gas and dust, called the primitive solar nebula, that formed around the Sun. Many of these theories speculate that the Sun and the planets formed together from the primeval solar nebula. A photograph taken in 1984 of a nearby star, Beta Pictoris, appear .....

.... arctic and Antarctic. George W. Wetherill even notes that “Even if a planet or moon could not support life globally, each could contain a tiny niche where life could thrive” (Science News, 328). What are the most favorable conditions for life to develop? It is now known that life simply cannot emerge anywhere that does not contain water. It is mostly preferred that this water exists in liquid form, but there are possibilities that life can form in freezing as well as boiling conditions. Water and energy, which both exist in many places in outer space, are prime biological prospecting sites. this ranges from deep sea thermal .....

.... of climate change, causes the heat problem. Because their cardiovascular system has to work harder to keep the body cool during hot weather. The temperature causes harmful effects to human health and another is cause of lung problem. "Higher air temperatures also increases the concentration of ozone at ground level". When this happens, the harmful ultraviolet radiation in the upper atmosphere reaches the earth's surface. The ESP states that "Ozone damages lung tissue, and causes particular problems for people with asthma and other lung diseases. Even modest exposure to ozone can cause healthy individuals to experience che .....
