.... sulfur dioxide, for example, comes from electric power plants burning coal or oil. Others are formed through the action of sunlight on previously emitted reactive materials. For example, ozone, a dangerous pollutant in smog, is produced by the interaction of hydrocarbons and nitrogen oxides under the influence of sunlight. Ozone has also caused serious crop damage. On the other hand, the discovery in the 1980s that air pollutants such as fluorocarbons are causing a loss of ozone from the earth's protective ozone layer has caused the phasing out of .....

.... 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 additives necesary for the production of borosilicate glass, calcination and elaboration of the glass. These operations are carried out in a metallic pot that is heated in an induction urnace. The vitrification of one load of wastes comprises of the following stages. The firs .....

.... ruins homes, and the acid can release lead in the pipes and the lead could go into our drinking water. It is hard to determine where acid rain may fall next, because the wind from a pollueted area could carry pollution to another area and the acid rain could fall there. The regions effected more by acid rain is large parts of eastern North America, Scandinavia, and central Europe. In alot of places acid rain isn't a probelm because some soils can neutralize the acid and it doesn't effect the crops. Areas more sensitive to acid rain is in the western United .....

.... If a retrievable facility (one where the casks of spent fuel can be retrieved later) is built, this will be a good deal more. Other disposal types, such as sub- seabed and space disposal may prove to be cheaper at a later time. This is a cause for concern, but there are a greater amount of reasons to further and eventually finish the Yucca Mountain Project. One is the desert climate naturally occurring in the western United States. The weather is dry and warm and their are very few natural disasters, such as earthquakes. Also, this part of the nation has a .....

.... the life of the universe. You would think of this as the end, but only an explosion is needed to wake up and give life to a new universe. Therefore, trapped forever in the cycle of rebirth. As humans we also travel through a cycle of rebirth according to the Hindu religion. We are all trapped on the Wheel of Samsara trying to break free. It is only possible to escape through the laws of Karma. Karma is simply how you act in this life determines what you are after your rebirth. For example, if you live each life being the best Hindu you possible can eventually your soul or Atman will be releas .....

.... the virus is present up to 7 weeks after being treated. Vomit and diarrhea contain the infected blood and mucus so any contact with this, e.g. in poor drinking water can cause contraction of the virus. Luckily enough Ebola is not airborne and in some cases due to its self-limiting nature, it has been known to die out within a person before killing the host. In one case when a Swiss researcher found the Ebola Tai virus, she contracted it from a chimpanzee. This was during an investigation into the spur of deaths among them at the time. To this day, there .....

.... carbon monoxide emission by increasing burning efficiencies. In its haste to declare MTBE as a required ingredient in gasoline, the EPA failed to consider a basic chemical property of MTBE and its long-term effects upon the environment. Because MTBE is highly water-soluble, it dissolves in water, leading to higher concentrations of MTBE in many lakes in the California Sierra Nevada mountains and in many groundwater supplies. Hence, by addressing only one component of a system separately, the EPA failed to see the ramifications of our apparent solution. This my .....

.... produce nearly ten times as much energy, while being only a fraction of the size. How the PEM Fuel Cell Works: A fuel cell is an electrochemical device that produces electricity silently, without combustion. Hydrogen fuel, which is one of the most abundant chemicals in the universe, and oxygen from the air are electrochemically combined in the fuel cell to produce electricity. Heat and pure water vapour are the only by-products of the fuel cell. The Ballard Fuel Cell is made up of two electrodes, the anode and the cathode, separated by a polymer membrane elec .....
