Seeing The Vessels Of The Retina
.... at the floor with their right eye.
I held the flashlight up towards the ceiling under their right eye, but they
kept looking at the floor, not the light.
RESULTS
I am writing down what everyone recorded for me. I am first:
JOSH: I could see black blood vessels with orange in the background...it looked
like a lot of dead tree.
BRENDA: The blood vessels resembled jagged lighting bolts or trees in the winter
time.
LAURA: I saw crooked lines that didn't stand still, but kept changing.
DARWIN: The i .....

Wavelength Of 10 Or Higher And 11 Down. Gamma Rays Are Produced In Labs
.... rays are also used for detecting
internal defects in metal castings and in welded structures. Gamma rays are used
to kill pesticides and bugs in food. Gamma rays are also used in nuclear
reactors and atomic bombs.
Gamma rays are often used in the food industry. The radioisotopes
preserve foods. Although the rays never come in contact with the food, Beta
radiation kills various organisms such as bacteria, yeast, and insects. Gamma
rays are sometimes used in science. They are used to detect Beryllium. The .....

Apollo 13 (AS-508): Houston, We Have A Problem.
.... increase within cryogenic oxygen tank 2. When
pressure reached the cryogenic oxygen tank 2 relief valve full-flow conditions
of 1008 psi, the pressure began decreasing for about 9 seconds, at which time
the relief valve probably reseated, causing the pressure to rise again
momentarily. About a quarter of a second later, a vibration disturbance was
noted on the command module accelerometers.
The next series of events occurred within a fraction of a second between
the accelerometer disturbances and th .....

The Hale Bopp Comet

object in the same field, and almost immediately suspected a comet, since I had
been looking at M70 last month, and *knew* there wasn't any other objects
there."
Thomas Bopp explains his story like this, "On the night of July 22, 1995
some friends and I headed out into the desert for a dark of the moon observing
session. The site, which is west of Stanfield, AZ and a few mile south of
Interstate 8 is about 90 miles southwest from my home.

Arizona Concrete
.... cement is produced by pulverizing clinker consisting
essentially of hydraulic calcium silicates along with some calcium aluminates
and calcium aluminoferrites and usually containing one or more forms of calcium
sulfate (gypsum) as an interground addition. Materials used in the manufacture
of portland cement must contain appropriate proportions of calcium oxide, silica,
alumina, and iron oxide components. During manufacture, analyses of all
materials are made frequently to ensure a uniformly high qu .....

Avalanches And Landslides

huge avalanche was triggered by the 1964 Alaskan earthquake. The slide spilled
out onto the Sherman glacier, during the big slide several other smaller slides
happened and those were the one that took lives in Anchorage, and destroyed
property
There are a couple of types of avalanches and how the destroy so much this one
is named "Loose Snow Avalanches"1, it starts' in a small area then grows in size
and mass as it descends.Another type is the "Slab Avalanche" it actually starts
in .....

Circulation Systems Over China
.... monsoon circulation which prevails over China
throughout the year.
Surface Pressure Field and Winds: For any fluid to initiate movements, pressure
gradient must exists. Therefore, for a close understanding of the circulation
system that operates over China, we should start from discussing the seasonal
pressure distribution at sea-level over the Asia-Pacific region, which is the
driving force for the air movements in China. Most clearly to be seen, the
largest difference in the atmospheric pressure occurs .....

Climatology
.... a triad of letter symbols. The first
(capital) letter is the critical one; the A climates are humid and tropical;
the B climates are very dry; the C climates are humid and mild; the D
climates reflect increasing cold; and the E climates mark the polar areas.
The first letter is followed by two more letters that further define the climate
of that region. The second letter represents and explains the dry season:
whether there is or isn't a dry season, whether it is a short or long dry
season, and what .....

Copper And Molybdenum Deposits In The United States
.... copper in the region of Lake Superior and the area natives had
copper jewelry and ornamentation. Earnest copper mining began in Simsbury,
Connecticut about 1709 and copper was actually exported to England after a
source was discovered in New Jersey around 1719. In later times domestic copper
resources did not satisfy national needs until the discovery of gold in
California shifted the focus of mineral exploration westward and strikes of rich
copper ores occurred in Tennessee and the Cordilleran base regio .....

Natural Disasters
.... effect on everyone.
The hurricane year is broken up into two seasons. They are referred to
as early season and late season. The early season starts June first and runs to
September 10. The late season starts on September 10 and runs to the end of
November. The date of September 10 is the midway point between the two seasons.
This is the date that separates early season from late season. This leads me to
what my research was about. I am writing about the differences between early
season and late season hu .....

Changes In The Earth's Environment
.... the environment as being truly threatened
by human progress and in desperate need of help.
Natural hazards have been defined as “...extreme geophysical events greatly
exceeding normal human expectations in terms of their magnitude or frequency and
causing significant damage to man and his works with possible loss of life.”
(Heathcote,1979,p.3.). A natural hazard occurs when there is an interaction
between a system of human resource management and extreme or rare natural
phenomena (Chapman,1994). As M .....

Fossil Fuel Consumption, CO2 And Its Impact On Global Climate
.... by use and the current consumption
patterns are non-sustainable. It is recognised that energy conservation and the
development of renewable energy sources will be needed to sustain economic
growth. The quantity of ultimately recoverable fossil fuels is limited by
geology and remains a matter of suspicion, but the view of the 1970s that
scarcity was imminent is still popular. It is the 1973 Oil Crisis marked the
transition from abundant, low-cost energy to an era of increasing prices and
scarcity. Toda .....

The Ocean
.... Thermohaline circulation.
Wind-driven circulation result from the wind sets the surface waters into motion
as currents. The currents generally flow horizontally-that is parallel to the
earth¡¦s surface. The wind mainly affects only the upper 100 to 200 meters of
water. However, the flow of wind-driven currents may extend to depths of 1,000
meters or more.
Thermohaline circulation produces great vertical currents' hat flow from the
surface to the ocean bottom and back. The currents largely result from
dif .....

Ocean Environment
.... and the differences in density are the major factor in understanding
the formation of currents and the positions of water masses in the sea. In
addition, temperature and salinity play major roles in influencing the
distribution of plants and animals.
The sediments of the sea floor may be divided into lithogenous,
hydrogenous, biogenous, and cosmogenous sediments. Lithogenous sediments are
the major sediments on the ocean floor. They are derived from the chemical and
mechanical weathering of rocks. .....

Tundra And The Artic
.... the summers are cool and short. Also due to the fact that much of
it's territory is located within the northern pole a lot of the Tundra receives
alternating 6 month periods of light and dark. This is also the reason why the
Tundra receives cold weather; at it's degree of latitude the suns rays end up
hitting the region obliquely, thus causing less solar heat. Here are the
temperatures of the Tundra in general:
Average January temperature: -32.1 degrees Celsius
Average July temperature: +4.1 degrees C .....
