Chromium
Number of Words: 483 / Number of Pages: 2
... used to make armor plating
for tanks and warships. They are also used for ball bearings and the hard
cutting edges of high-speed machine tools.
Nickel is highly resistant to electric current and is often added to
chromium steels to make them easier to work. For example, stainless steel
sinks can be pressed out from flat sheets of steel that can contain 18 percent
chomium and 8 percent nickel.
When nickel is mixed with chromium, the resulting metal can stand
very high temperatures without corroding. For example, the heating elements of
toasters can be made from an alloy that is 8 ...

The Role Catalysts In Chemical Reactions, Their Importance In Industry, Problems And New Developments
Number of Words: 1031 / Number of Pages: 4
... hydrogen ions, or protons: H+. Protons can be released
from hydrated ions, for example H3O+, but more commonly they are released from
ionisable hydroxyl groups (R-OH) where the O-H bond is broken to produce R-O-
and H+. When the reactant receives protons from an acid it undergoes a
conformational change, (change in shape and configuration), and becomes a
reactive intermediate. The intermediate can then either become an isomer by
returning a proton to the catalyst, or it may undergo a further reaction and
form a completely new molecule.
Up until the mid - 1960's silica-alumina gels were used to catalys ...

All About Ants (almost)

... habitats but the extreme arctics. Their
success is manifested in the claim that at any time there are at least 1
quadrillion living ants on earth(Groliers Œ93).
All species of ants are social. They live in organized communities or colonies,
which may contain anywhere from a few hundred to more than 20 million
individuals. These are organized into a complex system which may contain two or
more castes and sub castes which can be roughly organized into three groups.
Queens, males and workers.
The queen is much larger than the other ants, and has wings until mating. Her
primary task is to lay eggs ...

Creatine 2
Number of Words: 477 / Number of Pages: 2
... to stop producing ATP because of an overload of ATP being made from the Creatine. This can result in kidney or liver failure.
Constriction of the blood vessels occurs when you use Creatine and work out for extended amounts of time. This can cause major constriction of the vessels around the heart causing abnormal heart rates and heart attacks.
Pancretitis is another side effect where the pancreas stops working and fails. Creatine is said to be directly related to pancretitis if it is being used when it occurs.
Asthma is said to be directly related to some types of Creatine if they are used to do certai ...

Creation Of The Beach
Number of Words: 1256 / Number of Pages: 5
... water flowing parallel to the beach that is created by the action of waves breaking at an angle to shore. Longshore transport can deliver up to a million cubic yards of sediment annually to a single beach. In the second process, sand deposited onshore by the longshore current is then oscillated by waves breaking onto and receding from the beach. This continual onshore-offshore movement gradually pushes the sand along the beach edge. both the longshore transport of sediment along the coast and the movement of sand by waves along the foreshore are a part of the process called littoral drift.
The Califor ...

... it will need a little help. These two cells are then electrified thereby causing the two cells to fuse together combining their genetic structures.
Cloning / 3
Now that we have established the scientific basis of cloning, let me tell you how cloning can directly benefit humanity. There are many health issues that can be avoided, reversed and cured by the cloning of human cells and body parts. With the aid of cloning
technology, couples that have suffered infertility would be able to have their own biological children. Cloning technology may potentially be used to complete ...

Cable Modems Are The Wave Of The Future
Number of Words: 365 / Number of Pages: 2
... is up to 100 times faster than a 28.8 modem because of the high bandwidth that is available through coaxial cable lines. A 28.8 modem can transmit data at a rate of 28,800 bits per second. Cox@Home cable modems can transmit data at 1,500,000 - 3,000,000 bits per second saving the user valuable time and unneeded boredom.
Some factors that are beyond the control of the @Home Network can affect the speed of connection to the Internet. For example, the tremendous increase in Internet traffic over the last few years has resulted in a reduction of speeds and packet loss. Since bottlenecks can occur ...
