.... further behind other children the same age. Between 18 and 36 months old, they suddenly reject people, act strangely, and lose language and social skills they had already learned. During the 1950’s and 1960’s, people with were isolated and some were sent away to institutions. Today, many of those with can attend school with other children. Methods are available to help improve their social, language, and academic skills. Even though more than 60 percent of adults with continue to need care throughout their lives, some programs are beginning to demonstrate that with appropriate support, they can be trained to do meaningful work and participate .....

.... in the manufacturing of paper, plastics, insecticides, cleaning fluids, antifreeze, paints, medicines, and petroleum products. The unfortunate and unavoidable by-product of these manufacturing processes is dioxin, one of the most toxic substances on the planet earth. Dioxins are also produced whenever chlorine containing substances, such as PVC, are burned. Life as we know it will change, if a Greenpeace campaign is successful. The powerful environmental group has mounted a well-organized campaign that has as its objective nothing less than a total, worldwide ban on chlorine. With the public health and billions of dollars at stake, the debate .....

.... are characterized by bad feelings of sadness and despair that can become feelings of hopelessness and helplessness. Some of the symptoms of a depressive episode include anhedonia, disturbances in sleep and appetite, psycomoter retardation, loss of energy, feelings of worthlessness, guilt, difficulty thinking, indecision, and recurrent thoughts of death and suicide. The manic moods are made up by elevated or irritable mood, increased energy, decreased need for sleep, poor judgment and insight, and often reckless or irresponsible behavior. Bipolar affective disorder affects one percent of the population (approximately three million people) in the .....

.... is working closely with government agencies, universities and research centers to reduce the frequency and impact of oil spills. As a result of new operating procedures and research into advanced technologies, the industry has made tremendous progress in preventing spills over the past decade. In 1997, the latest year that Coast Guard statistics are complete, the volume of oil spilled in U.S. waters declined by two-thirds compared to the year before, representing the lowest amount recorded since the Coast Guard began publishing data in 1973. And more than three-fourths of those spills were under 10 gallons -- less than a car's fuel tank holds. .....

.... that fuels our economic growth. They power new industrial technologies that keep our economy growing and improve our global competitiveness. They cut America's demand for imported oil by nearly 100 million barrels a year—reducing our dependence on foreign oil suppliers and cutting our trade deficit. The future looks even better. Advanced-design nuclear power plants are now being developed—quicker and less costly to build, better performing, and even safer than today's plants. These plants will supply our children's and grandchildren's electricity—while helping to protect their environment. Cheers For Energy Efficiency .....

.... was maneuvered so its Apollo Telescope 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. Kerwin The crew meats with Skylab .....

.... that effects the entire structure. The bottom of the rainforest is the soil upon which everything must grow. Wherever rainforests are found, sandy red coloured soil can be found as well. This soil contains few nutrients, which is why attempting to grow any sort of crops would be futile. On top of this soil is a thin layer of humus, which simply said is the compost made from the millions of dead animals and plants of the forest. When things such as leaves and animals die their remains are quickly broken down by a limitless amount of tiny organisms. Some insects that do just this sort of thing include: beetles, ants, termites and a host of oth .....

.... that is lined with sharp teeth along the edges, thus, the name saw sharks. SQUALIFORMES: The order possesses three family which consist of about 82 species. These sharks are characterized by their slender, cylinder-shaped bodies, long snouts with shortened mouths. HEXANCHIFORMES: The Hexanchiformes or cow sharks, comprise of two families. Recognized by their six or seven pairs of gill slits, there sharks can often be found in deep water. The frilled shark (CHLAMYDISELACHUS ANGUINEUS) who's appearance is quite unmistakable due to it's "eel" like appearance, is perhaps one the strangest shark that exist today.

.... Union, Russia, and America. The Soviets are obsessed with space travel, and always have been. They posses an ideal vision of life on Mars. The Russians pride themselves for their excellent space survival. Unfortunately, the country does not have the funds to carry out their survival plans. Lastly, many believe an American flag should be placed on the planet of Mars. The Americans have greatly contributed to the findings on Mars; they have helped figure out that the temperature is cool and that the atmosphere is thin. America’s NASA deeply desires for Mars to be a useful planet. Many take-offs have been launched in recent years to carry ou .....

.... are passed down as the cell reproduces therefore spreading the cancer. Neoplasms are generally classified into two groups: malignant and benign. Malignant tumors, or abnormal tissue, grow more rapidly than benign tissue and they invade normal tissue. Benign tissue is structured similar to normal tissue while malignant tissue is abnormal and has an unstructured appearance. Of greater importance, benign tissue does not metastasize, or begin to grow in other sites, like malignant tumors do. Cancer always refers to metastasized tumors but the term tumor is not always necessarily cancer. A tumor is any living tissue that is #1 distinguisha .....
