tissues. The most frequently affected part is the leg. The most
common cause of lymphatic obstruction is filaries. Filaries is
caused chiefly by the species Wuchereria. When you have
wherever it is located your skin will become rough
and thickened like the skin of an elephant.
Over 1 billion people in 73 countries are at risk of getting
elephantiasis, and there are over 120 million people who
already have it.
New research has determined that albendazole, which has
already become a standard treatment to fight intestinal
parasites, is 99 percent effective against the parasite that
causes lymphatic filariasis. The diseas ...

Title: Solar Energy: An Alternative Energy
Details: Words: 290, Pages: 2... constant nuclear fusion reaction that is
taking place. The amount of energy at the solar constant, which is at outer edge
of the earth's atmosphere, is two calories per minute per cm squared. A calorie
is the amount of energy needed to raise one gram of water one degree Celsius.
If we could efficiently harness the energy bombarding the earth for twenty-four
hours we could power New York for a year. Unfortunately the photovoltaic cells
that change the energy into electricity are so inefficient that it would take
twenty-five years to pay for it's self in output.
There many uses of solar energy. Some homes rely fully on the power of the sun
to heat their water. Oth ...

3. It is seldom possible to count all the individuals in a given space. Explain one method by which biologists can study population densities without obtaining such data.
Scientist barely ever count the amount of individuals in a certain area because it would take too much time. Instead of actually counting the number of individuals in an area they would compare it with other areas where they know the population of individuals. In this way they can roughly estimate the number of individuals in a certain area.
4. What might happen to a rabbit population in an area where there are no predators?
If there were a few rabbits in an ar ...

Small cell carcinoma tumors are small and fragile. They are divided into groups by their shapes. The term “oat cell carcinoma” is used to develop in smokers and usually in the central part of the lung. They spread by the lymph glands and into the blood stream early. This type of tumors can only be seen through an electron microscope on high magnification. A rare type of lung cancer, which develops from hormone producing cells are carcinoid tumors. They have a much less malignant course than small cell carcinoma.
Lung cancer has been blamed on many factors but the most important is smoking ...

With all these harmful to children, there are ways to protect them from it. First, as a parent, don’t smoke. If you are a smoker, quit! If you can’t, don’t smoke in your house, in the car or near your children. Have a permanent place outside the house just for smoking purposes only. Make sure that your child's day-care, school or playgrounds are smoke free. Educate everybody you know about the hazard of secondh ...

Title: Cable Vs. V.90 Modems
Details: Words: 1217, Pages: 5... cable modem platform to end-users.
. Since cable modem technology is very recent the conflict exists between different standards. The only specification that has been approved by ITU (in 1998) is DOCSIS (Data Over Cable Service Interface Specifications) which was developed by MCNS, CabeLabs, Arthur D. Little and consortium of North American MCOs. Later that year CableLabs established certification program that would ensure interoperability among the equipment from different vendors. Certified cable modems are expected to appear in second quarter of 1999.
While waiting for the certificates vendor already started to develop the products that would meet new DOCSI ...

downdrafts are associated with critical wind shears. However, there are two
types of down drafts that are particularly hazardous to flight operations
because of there severity and small size. Professor T. Fulita, an
atmospheric scientist from the University of Chicago, coined the term
downburst for a concentrated, sever downdraft that induces an outward burst
of damaging winds at the ground. He also introduced the term microburst for
a downburst with horizontal dimensions of 4km or less (Lester 11-4).
Microbursts form by the same process that produce the more common and less
intense down drafts; that is, by precipitation ...

The second prayer called al-duhr (noon prayer) should be done between noon and the next prayer which is the asr (afternoon) prayer. The fourth prayer of the day is the Maghrib (sundown) prayer. The last prayer is called the Isha (night) prayer. If any prayer is missed at any time of the day for any reason, it can be made up at a later time. The next pillar of Islam is al-sowm (the fast). Muslims must fast during the Islamic month of Ramadan. Muslims engage in this practice in order to gain endurance and compassion for the poor. The four ...

Treatment
Because no drug developed so far has proved effective, treatment is entirely symptomatic. Use of moist heat coupled with physical therapy to stimulate the muscles was first initiated by the Australian nurse Elizabeth Kenny, and antispasmodic drugs are administered to produce muscular relaxation. In the convalescent stage, occupational therapy is used.
Disease Control
Three broad types of the virus have been identified: the Brunhilde (type 1), Lansing (type 2), and Leon (type 3) strains. Immunity to one ...

evolutionary process and the clarity of his work makes Charles Darwin the
most popular figure in the scientific field of Evolution (Francoeur, 1965,
p.34). Charles Darwin (1809-1882) was the fourth child of Dr. Robert
Darwin and grandson of Erasmus Darwin. Much of Charles' childhood was
spent collecting insects, coins and reading various literature on natural
history, travel and poetry. Charles Darwin was not a scholarly student
during his years at Edinburgh Medical College. He disliked what was taught
and found most of the lectures boring, yet he developed a natural interest
in studying r ...
