The Atomic Theory

(1868-1870), which later became a classic. These books included an improved version of the periodic table.
Sir Joseph Thomson, another important person in the development of the atomic theory, was born in
1906. Thomson won the Nobel Prize in physics (1906) for his work in the conduction of electricty through gases.
He discovered the electron by using cathode rays. An electron is the smallest particle of an atom, the charge on
an electron is negative.

The Prospect Of Cold Fusion
.... phenomenon that occurs when ordinary hydrogen and the special form of hydrogen called deuterium are brought together with metals, such as palladium, titanium, and nickel. Usually, some triggering mechanism, such as electricity or even acoustic energy, is required to provoke the "cold fusion" effects. Both ordinary hydrogen and deuterium are abundant in ordinary water so the process would likely end many of the world's energy concerns, if it can be developed commercially.
One of the biggest reas .....

The Y2K Problem
.... stop working altogether.
How might systems fail? Let's look at an example program in which the omitted century is assumed to be '19' and the program's function is to figure out how old you are. If you were born in 1958, then in 1999 this program will calculate your age as 99 minus 58, or 41. That's fine, but what happens when the century rolls over to '20' in the year 2000? In this program, the year will appear as '00' but the century will still be assumed to be '19' -- so the program will calculate y .....

The Use Of Pollen Analysis In

However skill on the part of the interpreter is required here as, already mentioned, certain plant types can over-represent themselves and the transport mechanisms of different plants may also vary, some for example being dispersed by insects whilst others are wind-blown. Pollen may also be found on a site as the result of other activities such as food preparation and consumption. The question w .....

Types Of Microphones
.... of microphones as basic equipment; the hand-held omnidirectional, the tiny lavalier mic, which is used by clipping on clothing, a wireless microphone called the transmitter mic, and the shotgun mic.
The Omnidirectional Microphone comes in many different shapes and sizes. They are used when the background sound is normally low. They usually work by pointing the mic directly at the source of the sound. This mic is not good for loud background sound because the mic might not be able to distinguish b .....

The General Effects Of Fire On

NEGATIVE EFFECTS - AQUATIC ECOSYSTEMS
Contrary to the beneficial impacts of fire on terrestrial wildlife, aquatic ecosystems are negatively affected, such as the decrease in fish populations by fire. In the North Fork S .....

The Jovian Planets

Jupiter, the first of the jovian planets, reigns supreme throughout the solar system. Named after the Roman god Jove, the ruler of Olympus; Jupiter is the fifth planet from the sun and is also the largest planet in the Earth’s solar system. It is 318 times more massive than Earth and is two thirds of the planetary mass in the solar system. Jupiter’s surface, unlike earth, is gaseous and not a solid. It is about 90% hydrogen and 10% helium with traces of methane, ammonia, water and rock. Jupiter’s interi .....

Transmission Of Aids

However, the risks increase sharply in the presence of other Sexually Transmitted Diseases (STD) i.e. gonorrhea, herpes and syphilis or when the infected person has symptoms of late HIV infection. Females have an eight times greater risk of catching the infection from an infected male than vice versa whereas anal intercourse without condoms carry the highest risk of and sexual activity. The chance of catching HIV from contaminated needles is extremely high (around 80%) .....

Knee Surgery
.... my recovery time would be similar to his. Never in my life have I been so wrong. Due to the nature of the injury, the doctor elected to stitch my cartilage back together. Because of the intricacy of the operation, I was restricted to non-weight bearing activities for three weeks. If I wished to return to wrestling, the doctor stated that I would have to demonstrate a muscle strength in my injured knee equal to ninety percent of my good one. When informed of this requirement, I could barely bend my .....

Kevlar

Kevlar 49 is used in mainly body armor and making architectural structures stronger (Sci. & Inv. Enc., 1354). Kevlar 49 is mainly made out of coal, corn, air, and water; making it rot and rust resistant. Compared to steel and concrete, Kevlar 49's psi (pressure per square inch) is 525,000, steel's is 36,000, and concrete's is 3,000 (New Necessities). The blast suppression, or body armor, is strong enough to endure machine gun fire (up to .3 caliber), land mines, terroristic w .....

Killer Bees
.... colony. Africanized honeybees have increased the number of human deaths due to bee stings in Mexico and Argentina and probably in other countries. In the United States, however, although more people have been stung by bees since 1990, no more bee-related deaths than usual have been recorded.
Conclusions:
The idea of “killer bees” is one that is created more by the media and misinformation than actual fact. Killer bees rarely—if ever—kill a victim. In addition, a killer bee scare in the United State .....

Because they often don't appear any different from anyone else, many XXY males probably never learn of their extra chromosome. However, if they are to be diagnosed, chances are greatest at one of the following times in life: before or shortly after birth, early childhood, adolescence, and in adulthood (as a result of testing for infertility).

Kawasaki Disease

This belief has been furthered by the fact that brothers and sisters often end up developing the disease, even though it is not contagious. However, the ultimate cause of the disease is still unknown.
One of the questions that have yet to be answered by any of the doctors is the cause of the disease. Kawasaki disease has no apparent cause. The disease i .....
