Pulmonary Agents
.... in the interior of many military vehicles). The oxides of nitrogen (NOxs) are components of blast weapons or may be toxic decomposition products. Smokes, e.g., HC, contain toxic compounds that cause the same effects as phosgene does. The remainder of this chapter will deal solely with phosgene because it is the prototype of this class of agents; however, the principles of medical management of phosgene exposure also apply to casualties from compounds such as PFIB or NOxs.
HISTORY/MILITARY RELEVANCE
Phosgene was first synthesized by John Davy in 1812. Subsequent development as a potential chemical warfare agent led to the first .....

White Tigers
.... tigers by having blue eyes, a pink nose, and creamy white fur with black stripes. Tiger’s stripes are just like a human fingerprint, meaning that no two tigers have the same pattern of stripes. White tigers are not usually born from other white tigers. They get their color from double recessive allele. A Bengal tiger with two normal alleles or one normal or white allele is colored orange. Only a double dose of the mutant allele results in white tigers, and you can only imagine how often that happens (www.cranes.org/whitetigers.com).
The white tiger has long been the focus of human fear and respect for years, because of it .....

Newton's Laws Of Motion
.... speed is called acceleration. An increase in speed is called positive acceleration, while a decrease in speed is called negative acceleration, or deceleration. Acceleration can also mean a change in direction as well as in speed. A force is needed to change the direction of an object, so a change in force can also mean a change in direction as well as a change in speed. According to Newton’s Second Law of Motion, the change in direction of a moving object depends on the applied force.
The amount of acceleration depends on the object’s weight. A lighter object will accelerate more than a heavier object. Newton’s Second .....

Solutions Around You
.... constant conditions. In a solution, one substance is usually considered to be dissolved, or broken down in another. The substance that is dissolved is called the solute. The substance that does the dissolving is the solvent. Not every substance dissolves in every other substances. A substance that dissolves in another substance is called soluble. Soluble means capable of being dissolved. A substance that does not dissolve is called insoluble.
TYPES OF SOLUTION
There are several different possible combinations of solute and solvent according to the physical state. It is useful, however, to categorize solutions accordi .....

What Is Macroevolution?
.... are for the rest of their existence. Phyletic gradualism suggests that species continue to adapt to new challenges over the course of their history. Species selection and species sorting theories claim that there are macroevolutionary processes going on that make it more or less likely that certain species will exist for very long before becoming extinct, in a kind of parallel to what happens to genes in microevolution.
The history of the concept of macroevolution
In the "modern synthesis" of neo-Darwinism, which developed in the period from 1930 to 1950 with the reconciliation of evolution by natural selection and modern ge .....

Are UFOs Real?
.... It states that the UFOs represent demons coming to earth for the final battle between good and evil (Randle 112). The not so widely accepted theory is that of hallucination/dream. Its major debunker is that mass hallucinations would have to be fairly common. The final hypothesis on UFO sightings is the null hypothesis, which states that they simply do not exist (Randle 114).
There are three different specific types of sightings. First comes the Close Encounter of the First Kind. In this setting, a UFO is seen at close range, but does not interact with its environment, this type is the most common (Arvey 54). Next are the Close .....

The Measurement Of Gas Exchange In Blue Gouramis
.... them to adapt to this problem. Since water contains an insufficient concentration of oxygen, fishes use gills to obtain the required amount of oxygen---via the counter-current exchange process. As water enters the mouth of a fish, it passes through slits in the pharynx, flows over the gills, and exits at the back of the operculum (gill cover) (Campbell 1997). This ventilation process serves to bring in a fresh supply of oxygen to the fish and removes carbon dioxide expelled at the gills (Campbell 1997). The water that flows across the gills flows in the opposite directions as compared to the direction of the blood flow in t .....

Genetic Cloning
.... attempt. The point is however that we now have a man created sheep, what else could be done in the near future.
There are many different goals for genetic cloning. Would you like to clone someone close to you who had died? In the movie “Gattaca” you get a peak at something that could be made possible by cloning, the genetic engineering of children not yet born. It could be the end of birth defects. If given the choice to be able to make a child perfectly healthy and have the traits you want in your child, would you do it? Infertile couples would be able to have babies. Organs could be cloned for transplants, no more .....

Human Cloning

Another is as the cells duplicate they usually do not make it passed the 32-cell stage or 64 because of abnormalities in the environment or just because the process is not natural. The real reason why it does not work yet is not clearly known at the moment.
Since human cloning became such a distinct possibility with Dolly being born many ethical and moral issues have been brought up. First off cloning takes out the entire autonomy of childbirth. You would now have many children with identical features causing those chi .....

Little Green Men Or Just Little Microscopic Organisms?
.... due
to a collision of an astroid that would have set back the evolution process of
Mars, causing it to be a harsh planet. A Viking spacecraft which landed on Mars
in 1976 found that the planet was bathed in ultraviolet radiation, "intense
enough so it would probably fry any microbe we know on this planet,"says Jack
Farmer, an Ames researcher who calls himself an "exopaleontologist"—a searcher
for fossils on other worlds. The redness of Mars is due to the chemical assault
known as oxidation, which turns iron compounds into rust, and it would surely
kill anything that sticks its head up.
"So why do you still believe that there is .....

BETA PICTORIS: PLANETS? LIFE? OR WHAT?
.... nebula had surrounded the sun, long ago, in order
for our solar system to form and take on their currents motions (1).
In 1755, a German, named Immanuel Kant, reasoned that “gravity would
make circumsolar cloud contract and that rotation would flatten it (1)." Thus,
the cloud would assume the general shape of a rotating disk, explaining the fact
that the planets, in our solar system, revolve in a disk-shaped distribution.
This idea, about the disk-shaped nebula that was formed around the early
sun, came to be known as the nebula hypothesis (1). Then, in 1796, a French
mathematician named Laplace, proposed that th .....
