Chicken Pox With Works Cited
... characterized by an eruption or rash, from the Latin and Greek word exanthema, meaning to break out, or, originally, to bloom. Many people were misdiagnosed due to the similarities between these diseases, and the fact that they can occur in milder or more sever forms leading to an overlap of the most obvious symptoms. (7)
Chickenpox mostly occurs in children classifying it as a childhood disease although it can occur in adults who are not yet immune to it. This could lead to the belief of chickenpox being one of the oldest diseases. Since the chickenpox infection has two phases, one most common during ...
Lab: Determining What Type Of Stimulus Info Is More Easily Remembered
... CVC is used, rather than in random
Remembering is the retrieval of information, which is stored in memory.
The act of remembering takes place when a correct response is given to a
certain stimuli presented. Forgetting is a weakening of this stimulus-
The Purpose of this experiment is to determine what type of stimulus
information is more easily remembered, be it in randomized manner or
meaningful. When are more errors made in remembering the stimuli, among
these two types of stimuli used (CVC). Also, when a correct respon ...
Docking With Mir
... the Mir space station. We couldn't give up the hope of peace
Launch Day had arrived; June 29, 1995. During launch and ascent, there
wasn't much to think about except the thrill of the ride. Then the tension rose.
In less than thirty-six hours, they would have to close a gap of four thousand
miles at an altitude of 245 miles while traveling at 17,500 miles per hour, only
to have to move within three inches and two degrees of a quickly moving, very
fragile object in space. One small thrust of a poorly aligned engine could cost
one of four space-worthy shuttles and the world's first and only long-term sp ...
... occur within seven days. Usually when a person becomes infected cutaneously the bacterium enters a cut or abrasion on the skin, such as when handling contaminated wool, hides, leather or hair products (especially goat hair) of the infected animal. A skin infection begins as a raised itchy bump that resembles an insect bite, but within one to two days it develops into a vesicle and then a painless ulcer, usually one to three centimeters in diameter with a black necrotic (dying) area in the center of the ulcer. Lymph glands in the adjacent area may swell. About twenty percent of untreated cases of cutaneous anthrax wil ...
Greenhouse Gases And Consequences
... rays have a longer wavelength than visible light, and for this reason can be absorbed by certain gases in the atmosphere, labelled greenhouse gases. This absorption of heat warms up the atmosphere, which in turn radiates some of the heat back to the earth.
Greenhouse gases include water vapour, carbon dioxide (CO2), methane (CH4), chloroflurocarbons (CFCs), Ozone (O3), and Nitrous Oxide (N2O).
It all seems very straightforward: greenhouse gases trap the sun's heat, warming the planet sufficiently for life to exist. There is, however, one problem: human activity has dramatically increased the amount of greenhouse ga ...
Genetic Engineering And Its Fu
... unethical to modify life. Changing life to service us is not morally wrong. It is not inhuman either. Of course, if you believe using animals for scientific research is morally wrong that's your belief, I am stating that genetically enhancing them to be better research specimens is not unethical. My reason behind this is that we don't just do research in order to infect and kill off the mice, we do it so one day we will have a cure for cancer and can save hundreds of thousands of human lives. Of course if you value the life of a mouse over a human then you would see differently. Some fear that this science is too po ...
The Comparative Abundance Of The Elements
... the 17 elements that make up 99.5%, the most abundant of
these are Oxygen 49.2%, Silicon 25%, and Aluminum 7.5%. Then the next most
abundant elements are Iron 4.7%, Calcium 3.4%, Sodium 2.6%, Potassium 2.4%,
Magnesium 1.9%, Hydrogen 0.9%, titanium 0.6%, Chlorine 0.2%, Phosphorus
Manganese and Carbon are all 0.1%, Sulfur 0.05% Barium 0.04%, Nitrogen 0.03% and
the rest of the elements on the periodic table take up about 0.5%.
The elements of the crust are graphed below, but only ones that are the
most abundant due to the fact that the abundance of the other elements of the
crust are too low to graph accurately on ...
Ebola Virus 2
... 1976 in Zaire, followed by an out break in western Sudan almost immediately afterwards. The third out break in Sudan in 1979 was smaller with 22 deaths out of the 34 cases. The first outbreaks in Zaire and western Sudan were large resulting in 340 deaths out of the 550 cases.
The most recent outbreak is in Kikwit, Zaire. The outbreak appears to have started with a patient who had surgery in Kikwit on April 10, 1995. Members of the patient's surgical team developed symptoms similar to those of a viral hemorrhagic fever disease.
The symptoms of Ebola hemorrhagic fever begin 4 to 16 says after infection. Victim ...
Hard Drive Evolution
... installations. Vast "disk farms" of giant 14 and 8 inch drives costing tens of thousands of dollars each buzzed away in the air conditioned isolation of corporate data centers. The personal computer revolution in the early 1980s changed all that, ushering in the introduction of the first small hard disk drives. The first 5.25-inch hard disk drives packed 5 to 10 MB of storage, the equivalent of 2,500 to 5,000 pages of double-spaced typed information, into a device the size of a small shoebox. At the time, a storage capacity of 10 MB was considered too large for a so-called "personal" computer.
The first PCs used re ...
Mass And Science
... that works like a sea saw.
Mass is a measure of the amount of matter in an object. Both living and nonliving things are made up of matter. Matter is anything that has mass and takes up space. Most matter on earth exists in three states: liquids, solids, and gas. All matter is made up of tiny particles called atoms. An atom is the smallest unit of matter that can exist and still be recognized. You and all the things around you are made of matter.
Since we all live at the surface of the earth where the acceleration of gravity is relatively constant, it has been natural for us to confuse the concepts of mass ...
