... it had no effects on the lab animals, therefore its study was discontinued. LSD’s study was revived in 1943, when research indicated it could potentially be used as treatment for schizophrenia, due to its similarity in structure to Nicatamide, a chemical found in the human brain, which directly affects the experiences of a Schizophrenic (DEA,1). On April 16, 1943, while Dr. Hofmann was measuring a fresh quantity of LSD, he accidentally dosed himself and was overcome with confusion. He was then obligated to leave work due to “a sensation of mild dizziness” and “extreme activity of imagi ...

... day. Some products developed in NASA's space program that we now incorporate in our daily lives include the vacuum cleaner, pacemaker, pens that can write upside-down, and the zero-gravity training system. The vacuum cleaner was originally a great tool for astronauts in outer space. It is now a very helpful tool for cleaning our homes. The pacemaker is a form of life-support on spacecrafts, helping astronomers' hearts pump while they are outside of the Earth's atmosphere. It is used, on Earth, for those who's hearts have problems with pumping blood. Pens that write upside-down are used in space, where there i ...

... Mt. Hood, Mt. Etna, Vesuvius, and Mt. Saint Helens are examples of volcanic mountains. Rocks are hard but in time they can bend or fold producing Folded mountains. The Alps formed as the Eurasian plate pushed against the African plate. Other examples of folded mountains are the Rockies, Himalayas, Appalayas, and the Andes. Fault-block mountains are formed when one plate pushes or pulls away from another plate. In the Earth, hot currents of magma or molten rock may well up and crack the weakened crust above. As the crust cracks, blocks of rock rise or fall forming Fault-block mountains. Examples o ...

... of it fill city streets, the first and even second floors of buildings, automobiles and anything else that may have fallen victim to the hurricane's epic floodwaters. Workers hack and chip at the mud with shovels and pickaxes, and an endless procession of shopowners scurry between their gutted businesses and the river in a desperate attempt to wash and salvage their goods. A muddy valley runs past the Central Prison, where some of the incarcerated swam to freedom as Mitch's floodwaters rose and propelled them over the walls. Hundreds of homes, streets, and businesses were washed away, and those that remaine ...

... difficult and the resulting compounds quite unstable. Helium is the most difficult of all gases to liquefy and is impossible to solidify. These properties make liquid helium extremely useful as a refrigerant and for experimental work in producing and measuring temperatures close to absolute zero. Liquid helium can be cooled almost to absolute zero at normal pressure by rapid removal of the vapor above the liquid. At a temperature slightly above absolute zero, it is transformed into helium II, also called super fluid helium, a liquid with unique physical properties. It has no freezing point, and its viscosit ...

... resistance of this organism. But while research continues, it is vital to be aware of how these deadly germs spread and what we can do to prevent them. Long before humans discovered antibiotics, they existed in nature. So naturally, after penicillin was introduced, some germs were already naturally resistant to the drug. As we used more and more of the antibiotics, we incidentally caused drug-resistant germs to progress. So, even if you’ve never misused antibiotics, you could still become infected by bacterium most drugs won’t kill. For each drug, there are germs genetically programmed to survive- som ...

... was the start of time and space. The matter and radiation of that early stage rapidly expanded and cooled. Several million years later, it condensed into galaxies. The universe has continued to expand, and the galaxies have continued moving away from each other ever since. Today the universe is still expanding, as astronomers have observed. The Steady State model says that the universe does not evolve or change in time. There was no beginning in the past, nor will there be change in the future. This model assumes the perfect cosmological principle. This principle says that the universe is the same everyw ...

... to move. Then the wolf pack can eat and tear him apart at their own will. Although savage and bloodthirsty, wolves are among some of the world's smartest and most perceptive mammals. Where found: Wolves are found all over the world, and on almost every major continent of the earth. The following wolves are types of Gray Wolves (Canis lupus). In eastern Europe the European Wolf (Canis lupus lupus) can be found even though it used to roam most of western Europe as well. In Spain, two wolves have also been identified-Canis lupus deitanus and Canis lupus signatus. While the first is similar to many of the other ...

... or work, even when there is no sign of difficulty. They also have trouble relaxing and they often have insomnia. Many live from day to day with distressing physical symptoms such as trembling, sweating, muscle tension, stomach pains, or headaches that tend to worsen when they face even mild stress (Harvard Health Letter, 1998) In 1994, generalized anxiety disorder (GAD) became an identifiable mental disorder with a DSM-IV diagnosis. The diagnostic criteria for GAD are: A. Unrealistic or excessive anxiety and worry about life circumstances for a period greater than 6 months, during which this person has been ...
