... on how far the photon has dropped between the orbitals. Tom adds that collision of an atom and a photon leads to the absorption of the photon’s energy by the atom prompting the electron jumping to a higher energy level. Further as the electron falls back to its original energy level, it releases extra energy in the form of a light photon. X-ray photons have too much energy than enables them to pass through most things including the human body. According to Tom, the “heart” of an x-ray machine is an electrode pair, a cathode and an anode that sits inside a glass vacuum tube. He further advances that the cathode is a heated filament similar to an older fluorescent lamp. The x-ray machine passes current through the filament, heating... is...

...Jonathan Davis Mr. Jelle Roos ENC1102 February 15, 2007 Cellular Phone Use While Driving: A Death Sentence It is often argued that when using a mobile phone while driving, it causes a big enough distraction to be responsible for many traffic accidents. This view is supported by many studies that conclude there is a higher collision risk, and that motorists who do talk while driving are more likely to lose control of their vehicles. This has been found even when drivers are using hand-free systems. Despite this, the U.S. National Highway Traffic Safety Administration (NHTSA) found that 10% of all people operating vehicles on the road during the day were using cell...

Driving distraction has been a focus of study since the early1900's when researchers examined the 'hypnotic effect' of windshield wipers (Curry 2002). The concept of safety and 'paying attention' then is not a new concept, it has been a focus of research since the use of vehicles began. In the multi-media age, people use cell phones and personal hand held computers to stay...

.... (1997), they said that we should have a better understanding of the nature and magnitude of any road safety problem rather than restricting cell phone usage while operating a motor vehicle. Therefore, they recommended that we should make in vehicle information system that would reduce accidents on our roads. For this source they are looking in ways on how we can reduce road accidents on the roads rather than banning their usage which might be just a partial solution. The source is common to the others because it is addressing how not only can we reduce accidents by banning cell phone usage while driving but we can further reduce them by innovating our...

The prevailing changes in climate temperatures, ocean currents and landscapes caused by global warming will lead to an increase in the incidence of natural disasters such as tsunamis and hurricanes. The tsunami that hit South Asia in December 2004 resulted in approximately 47,000 deaths in Sri Lanka, India, Bangladesh, Thailand and Burma. Global warming experts believe that although tsunamis are natural occurrences, this one was particularly deadly because of rising sea levels in these areas-the work of global warming. Climatic alterations have increased sea level up to 10-20cm in some areas, compared to...

...caused by cellular usage because these drivers whether using a hands-free kit on their cellular phone, still lose concentration while driving. They did not find any safety advantage of the hands-free over the hand-held device. Besides, cell phones allow drivers to make emergency calls.
Hence, Redelmeier and Tibshirani (1997), suggest that it is important to have a better understanding of the nature and magnitude of any road safety problem rather than restricting cell phone usage while operating a motor vehicle. An in-vehicle information system or a driver assistance system could reduce road accidents. Banning their...
