... which is mostly
limited to vaccinations. With vaccinations there are two types of
immunization, which are Active and Passive immunization. The difference
between the two is that Active immunization is used to control a disease on a
long term basis, where Passive immunization is used to treat a disease quickly
but only lasts a few weeks. Passive immunization works immediately but does
not last where Active immunization takes about two weeks to work and lasts
many years. There are many vaccines to prevent Encephalitis and some of the
most common diseases in this topic are Measles, Mumps and Rubella,
Nuclear Power: Cons
... those at Chernobyl are slowly rendering Nuclear Fission an obselete energy
source. This essay will prove that nuclear power is a dangerous technology and
with many other sources and the dangers involved, the disadvantages of nuclear
power far outweigh the benefits.
Alternative sources of energy are making their way into the highly
competitive field of electricity production. With the wealth of sources such as
solar, wind, hydro or geothermal the dangers involved with fission could be
solved by adopting these newer, safer methods. A main source of energy that
could lead the way for the near future is solar energy. ...
... powder, clear and colorless in solution. With its popularity, you may find creatine at any health or sport product retailer. It sells for roughly $35 a bottle, and is distributed by many manufacturers. Creatine serves as an energy reserve in muscle cells. Muscular contraction is powered by the breakdown of ATP (adenosine triphosphate) to ADP (adenosinediphosphate). When all the ATP is broken down, creatine phosphate in the muscle donates a phosphate group to ADP, and further energy reactions can occur. Creatine Monohydrate is a precursor to creatine phosphate. By supplementing with CM, CP levels in m ...
Problems Caused By Air Pollution
... tri-state valley bounded by Kentucky, Ohio, and West Virginia
have claimed to suffer from health problems, including rashes, respiratory
problems and even cancers" (D4). In 1948, in the industrial town of Donora,
Pennsylvania, which sits in a valley, had twenty deaths, and nearly 6,000
residents, or 40% of the population, suffered respiratory problems (Edelson 25,
26). New York experienced several killer smogs, which in a later analysis
attributed, from the usually severe pollution, 58 deaths (Edelson 26). Not only
in the United States are health problems caused by air pollution showing up, but
they are also sh ...
... bombs were used was called the Manhattan Project. The Manhattan Project was created by the United States government in 1942 to produce the first nuclear bomb. The official agency that produced the bomb was the Corps of Engineers’ Manhattan Engineer District, commanded by Major General Leslie R.Groves. He directed industrial and research activities at such sites as Oak Ridge, Tennessee, and Los Alamos, New Mexico (The World Book Encyclopedia 141). Here they designed to bombs that were later called “The Fat Man” and “The Little Boy”. There was later a movie named after the two bombs that showed how they were m ...
The Superstring Theory
... Physics community regardless of deference or validity. Please keeps these points in mind, and remember that Aristotle said, "All men by nature desire to know."
One day, a promising physics student walks into a professor's office wanting to find out what physics could teach him. This student, only having a rudimentary knowledge of physics, asks, "Can you give me a definition of physics?" The sage rolls his eyes back, and rubs his temples. He replies, "Big or small?" The student baffled by this, prompts again, "Um, physics?" The teacher noticing the ignorance in the room explains, "Physics is split into two maj ...
The Peregrine Falcon
... were once trained by kings to hunt and bring back
kills. This sport, called Falconry, is still popular. However, in the
1960s the American falcon came close to extinction. Most of the damage was
done by poisons that farmers used to kill insects. The worst poison was
DDT. By the time naturalists learned of DDT's effect on wildlife, it was
almost too late.
The American peregrine's scientific name is Falco peregrinus anatum.
At one time, people called this falcon a duck hawk. That was a poor name,
since falcons aren't hawks and they rarely kill ducks. The American
peregrine was once found all across the east ...
... Any of these performances are usually accompanied by dramatic changes in the patters or intensity of colors of the fish. Males and females tend to advertise their sex and availability through vibrant colors. This sexual dimorphism is most evident in such reef residents as groupers. The color patters change predictably from the "juvenile: to the "initial" subdued pattern of small adults to the "terminal" pattern in the largest adult males. The terminal male is the one with the brightest colors and gaudiest patterns.
The moon seems to play an important role in fish reproduction. According to Peter H. Pressley, i ...
The Black Hole
... is generally formed,
how it functions, and the effects it has on the universe.
In order to understand what exactly a black hole is, we must first take
a look at the basis for the cause of a black hole. All black holes are
formed from the gravitational collapse of a star, usually having a great,
massive, core. A star is created when huge, gigantic, gas clouds bind
together due to attractive forces and form a hot core, combined from all
the energy of the two gas clouds. This energy produced is so great when it
first collides, that a nuclear reaction occurs and the gases within the
star start to burn continuou ...
... are manufactured many chemicals are
used to create it. However because of the difficulty and cost of properly
disposing of these products they are often emitted into the atmosphere with
little or no treatment.
The term was first considered to be important about 20 years ago when
scientists in Sweden and Norway first believed that acidic rain may be causing
great ecological damage to the 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 ...
