.... viruses, we are the invaders (Baddorf, Ourworld.compuserve.com)." Between the years of 425BC-430BC Athens' population was dramatically reduced when about 300,00 of its inhabitants died from some sickness. Some people now believe that this great plague was really Ebola. The first recorded outbreak of the Zaire string of the Ebola virus was in Zaire, in 1976. The doctors didn't know how to treat it and that meant that they didn't know how to contain it either. As infected people met in public places the virus spread. In Western Sudan, the same year, the Sudan string of the Ebola virus emerged with similar results. Both casts togeth .....

.... All are formed from the gravitational collapse of a star, usually having a great, massive, core. A star is created when huge, gigantic, gas clouds bind together due to attractive forces and form a hot core, combined from all the energy of the two gas clouds. This energy produced is so great when it first collides, that a nuclear reaction occurs and the gases within the star start to burn continuously. The Hydrogen gas is usually the first type of gas consumed in a star and then other gas elements such as Carbon, Oxygen, and Helium are consumed. This chain reaction fuels the star for millions or billions of years depending upon the amount .....

.... Mount (ATM) solar panels faced the Sun to provide as much electricity as possible. Because of the loss of the meteoroid shield, however, this positioning caused workshop temperatures to rise to 126 degrees F. The launch of Skylab 2 was postponed 10 days while NASA engineers developed procedures and trained the crew to make the workshop habitable. At the same time, engineers "rolled" Skylab to lower the temperature of the workshop. Skylab's 2nd manned mission - May 25th to June 22nd Astronauts; Charles Conrad, Jr. Paul J. Weitz Joseph P.

.... problems from bed-wetting, however, some children who wet the bed can develop psychological problems, including low self-esteem. This disorder also affects family members through anger and frustration because of the condition. One important reminder to parents with children who suffer from this condition is that bed-wetting should not be thought of as a behavioral problem.

As parents, the best way to help your child is to be understanding and remember that punish .....

.... to be important about 20 years ago when scientists in Sweden and Norway first believed that acidic rain may be causing great ecological damage to the planet. The problem was that by the time that the scientist found the problem it was already very large. Detecting an acid lake is often quite difficult. A lake does not become acid over night. It happens over a period of many years, some times decades. The changes are usually to gradual for them to be noticed early. At the beginning of the 20th century most rivers/lakes like the river Tovdal in Norway had not yet begun to die. However by 1926 local inspectors were noticing that many of .....

The present paper seeks to explore current research through investigating the social and bio-genetic influence of . Testing and treatments of those with ADHD will also be discussed. In accordance with Dulcan et al. (1997) ADD, ADD-H, ADHD, although not identical, will be considered interchangeably due to similarity.
