Hemophilia Manitoba
Number of words: 925 - Number of pages: 4.... and all of his daughters will be carriers
of the hemophilia disorder because all he can pass on is
the defective X-chromosome.
Males mostly have hemophilia, but women can also have
hemophilia. This is extremely rare though because two
defective X-chromosomes would be needed. In fact, the
first proven case of women having hemophilia was not until
the 1950’s (Bornstein 89). Female carriers are also at
risk. These women are known as asymptomatic carriers and
may suffer excessive menstrual bleeding, bruising,
nosebleeds, and problems during childbirth.
One serious pro .....

The Beauty Of Rainbows
Number of words: 252 - Number of pages: 1.... a rainbow is a curve of colored light which is seen in the
sky. Rainbows can be seen in moonlight or in artificial light. They are caused
by the sun shining through tiny drops of water in the air. A rainbow's
brightness depends on how large the drops are. The larger the drops are the
brighter the rainbow will be.
Many people think that a rainbow is only made of six colors, but it is
really make of seven. The colors in order are red, orange, yellow, green, blue,
indigo, and violet. A primary rainbow is a rainbow with red on the outside and
violet on the inside. The largest rainbow visi .....

Gallium
Number of words: 487 - Number of pages: 2.... gallite. It is
extracted as a by-product from zinc blende, iron pyrites, bauxite, and
germanite.
Silvery white and soft enough to be cut with a knife, gallium takes on a
bluish tinge because of superficial oxidation. Unusual for its low melting
point ( about 30 degrees C, 86 degrees F ), gallium also expands upon
solidification and supercools readily, remaining a liquid at temperatures as
low as 0 degrees C ( 32 degrees F ).
Gallium has the longest usefull liquid range of any element. The liquid
metal clings to glass and similar surfaces. The crystal structure of gallium
is orthorhomb .....

Acid Rain
Number of words: 1940 - Number of pages: 8.... 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 lakes were beginning to show signs of death. Fish were
found dead along the banks of many rive .....

Nuclear Weapons

to keep a person's heart beating. We did begin to produce more plutonium
but the majority of the substance was used towards our nuclear weapons
programs.
Along with reactors, sometimes comes a meltdown which can cause
harmful effects if it isn't controlled quickly enough. After such
instances as the Hanford, Washington reactor meltdown and the accident in
the U.S.S.R. at the Chernobyl site, no one wanted to hear about the use of
plutonium. The United States government banned nuclear testing and also
ended the .....

Electrical Energy
Number of words: 231 - Number of pages: 1.... the rate at which the capacitor is discharged, which is the current, is decreased. The outcome of this is that the capacitor will be completely discharged meaning that both the current and voltage will equal zero. At this time all the energy stored in the circuit will have been transferred to thermal energy at the resistor.
A heater uses electrical power. The power dissipated in a resistor is in return proportional to the resistance and the square of the current that passes through it. As the energy is changed from electrical to thermal the resistor gets hot.
In long distance transmission, cu .....

Hanta Pulmonary Syndrome
Number of words: 414 - Number of pages: 2.... as woodpiles and sheds where there is little air circulation to move off the virus, it can linger for a sizeable duration of time.
The best method of fighting the hanta virus is prevention. By controlling the rodent population and preventing them from entering houses and sheds, the risk of infection can be lowered. Furthermore, educating those in high-risk areas of the signs of the disease and what to do about them significantly lowers the likelihood of death.
The virus cannot spread from human to human even during its peak state, but since exposed persons may not show symptoms for some we .....

Dolphins & Humans: Breaking Barriers Of Communication

Plutocrat wrote Thathos, Odysseus' son, was saved from drowning as a young child through the aid of a dolphin. A roman scholar Plink the Elder, who lived in AD 23-69, wrote about a boy named Hermias. Hermias had many encounters with a friendly dolphin which he would except rides from. One day Hermias was thrown off the dolphins back by a sudden storm and drowned in the sea. The dolphin brought the boy's body back to the shore, and the dolphin threw itself on the sh .....

The Landsats Satellites
Number of words: 1099 - Number of pages: 4.... radiance data with multispectral and panchromatic scanning capabilities. The multispectral mode captures data in three bands in the following spectral ranges: .50-.59, .61-.68 and .79-.89 micrometers. The three bands are co-registered and have a ground resolution of 20m. The panchromatic mode images data in the spectral range .51-.73 micrometers at a sampling interval of 10m.
LITERATURE REVIEW
Landsats 1 through 3 circled the Earth every 103 minutes, completing 14 orbits a day. Eighteen days and 251 overlapping orbits were needed to provide almost complete coverage of the Earth .....
