Modernization Of Computers
Number of Words: 544 / Number of Pages: 2
... and an electronic suit. Fastened tothe suit are sensors, which send information to the main computer. Thiscomputer works with the data and displays them on the electronic spectacles. This is a technique which use three-dimentional views, therefore the scenery seems incredibly realistic. If you want to be a boxer, simply change thescenery on the main computer, and you are in the ring.Today, many kids have got video games. You could say these games are thepresent's answer to ludo and monopoly. In a way, it is a great advantage thatthe kids are being presented to computors at an early age, because they w ...

... who favor public expenditures to hold back the sea and other public officials and some scientists who are skeptical about erosion-fighting programs. There were those who believed people should not be allowed to rebuild in hazardous areas and those who would not forbid them to build as long as they did not ask for recompense when they got into trouble. One group has felt property owners should not be compensated if they are forbidden to rebuild, and others say it is unconstitutional to take property without compensation.
The November 1997 meeting helped to demonstrate that the issue of sea le ...

Local Area Network Bridges

... and high-bandwidth feature but its topology may be more dynamic than in a single LAN due to possible bridge or LAN failures and hosts being moved around.
Bridge routing algorithms should meet the following requirements:
1) A bridges LAN environment should resemble a single LAN environment as closely as possible. In other words, the extension should be transparent to hosts.
2) The transparency requirement extends to performance requirements, such as low transmission delays, low undetected data corruption and FIFO maintenance.
3) Bridges routing algorithms should be able to adapt quickly to en ...

Nucleic Acids
Number of Words: 425 / Number of Pages: 2
... nucleotide has three parts:
A Five Carbon or Pentose Sugar
The sugar will be one of two very similar pentose rings. Ribo contain the sugar ribose. Deoxyribo contain the sugar deoxyribose. The only difference between these two sugars is that deoxyribose contains one oxygen atom less than ribose. Pentose sugars are essential because they are involved in linking different nucleotides together by condensation reactions.
The Nitrogen-Containing Bases
There are two types of bases found in nucleic acids. The purine bases have two nitrogen containing rings, while the pyrimidines have only one. In DNA the ...

Forests Cannot Absorb CO2 Emissions
Number of Words: 329 / Number of Pages: 2
... Experts hope that this new way to cut back on
these CO2 emissions will not be costly and time consuming.
Dry air is made up of about 78 percent nitrogen and 21 percent
oxygen. For living things, the two most important gases are oxygen and
carbon dioxide. All plants and animals in respiration use oxygen.
Respiration is the process by which food is changed to energy.
Photosynthesis is the process by which plants make sugar and starches.
Thus nature restores oxygen and carbon dioxide to the air about as fast as
they are used up.
There should be money invested in to this because it will help the
envi ...

Mechanics: Statics And Dynamics
Number of Words: 1552 / Number of Pages: 6
... role in engineering than does mechanics, and it is the oldest of
all physical sciences. The writings of Archimedes covering bouyancy and the
lever were recorded before 200 B.C. Our modern knowledge of gravity and motion
was established by Isaac Newton (1642-1727).
Mechanics can be divided into two parts: (1) Statics, which relate to
bodies at rest, and (2) dynamics, which deal with bodies in motion. In this
paper we will explore the static dimension of mechanics and discuss the various
types of force on an object and the different strength of materials.
The term strength of materials refers to ...

Bipolar Disorder 4

... between. Some individuals may display mixed symptoms of both mania and depression at the same time, while others may have fewer symptoms of mania (also referred to as hypomania). The type severity, and duration of mood episodes may vary. Some individuals may experience excessive mania, or excessive depression, and some may experience an equal amount of both. The mood episodes can last for a few days to as long as several months, especially when left untreated or not treated effectively. Usually a person with bipolar disorder can expect an average of ten episodes of either mania or depression in ...

Determination Of An Unknown Amino Acid From Titration
Number of Words: 1634 / Number of Pages: 6
... acids also exist. Amino acids may exists as acidic or
basic salts. For example, if the glycine reacted with HCl, the resulting amino
acid would be glycine hydrochloride (see fig. 2). Glycine hydrochloride is an
example of an acidic salt form of the amino acid. Likewise, if NaOH were added,
the resulting amino acid would be sodium glycinate (see fig. 3), an example of a
basic salt form.
Fig. 2
Fig. 3
Due to the nature of amino acids, a titration curve can be employed to identify
an unknown amino acid. A titration curve is the plot of the pH versus the volume
of titrant used. In the case of amin ...

Acid Rain

... many cones (Baines, 22). Secondly, acid rain
damages the trees through the soil by releasing metals that harm them even further (Lucas, 72).
Acid rain makes the trees lose their leaves, so when the trees try to regrow their leaves, buds
come instead, this process is called a panic shoot (M. 15). Large land areas which used to be
covered with forests are now gone, dead or dying (Baines, 21). Around the 1980’s more than half
Kotto 2
of the trees in Germany had signs of acid rain damage (Edmonds, 14). Now it is known that acid
rain is one of th ...

Twinning In Cattle

... move upward. The American
Breeder Service has made efforts to produce semen as well as embryos with high
predicted breeding values available to producers. They have been recorded based
on twinning probabilities and ovulation rates. A large amount of work on
twinning has also been done by the Meat and Animal Research Center. Since the
early eighties, they have located cattle with a high frequency of twinning and
been forming a breeding foundation based on this characteristic. “We believe the
time has come to make some of these unique genetic resources available to the
beef industry through artificial ...
