The Rain Forest - Example Of A Flourishing Ecosystem
... complicated structure which is put together from an
unlimited amount elements that all work together. A hole anywhere in this
system can cause a breakdown that effects the entire structure.
The bottom of the rainforest is the soil upon which everything must
grow. Wherever rainforests are found, sandy red coloured soil can be found
as well. This soil contains few nutrients, which is why attempting to grow
any sort of crops would be futile. On top of this soil is a thin layer of
humus, which simply said is the compost made from the millions of dead
animals and plants of the forest. When things such as leaves and a ...

Historic Model Of Science
... aided in transforming scientists, philosophers and others among them into cultural heroes. Science became a part of home life, when in previous times science was seen as a threat to religion and thus proclaimed as wrong. Once science became a part of life and began to prove and bluntly say things that the bible and religion could not come near to explaining, it became the basis for fact. The ‘heroic model’ could easily be blamed for the breakdown of the religious-infested societies that plagued the world.
This became very important to everyone involved, which proved to be more people than expected. ...

Internet History Report
... attempt, the “L” and “O” were transmitted successfully, but after they typed the letter “G” the system crashed.
From 1969 to 1983 a lot of different packet switching schemes were tried and
TCP/IP is what grew OUT of ARPANET, not what started ARPANET. During most of the
seventies, the protocol was generally referred to as just the Network Control Protocol or NCP. The term Internet was probably first applied to a 1973 research program that culminated in a demonstration system in 1977. It demonstrated networking through various mediums, including satellite, radio, telephone, ethe ...

Down Syndrome 4
... who were cretins and what he
referred to as "Mongoloids." Down based this unfortunate name on his notion
that these children looked like people from Mongolia, who were thought then
to have an arrested development. This ethnic insult came under fire in the
1960s from Asian genetic researchers, and the term was dropped from
scientific use. Instead, the condition became "Down's syndrome." In the
1970s, an American revision of scientific terms changed it simply to "Down
syndrome," while it still is called "Down's" in Europe.
In the first part of the twentieth century, there was much speculation of
the cause o ...

Frog Disection
... the anus. (Cooper, H, Hays, S, Walker.D, Linden R 1982)
The frog has three lobed livers. The functions of the liver, is to release digestive enzymes to help the stomach and the small intestine with mechanical digestion. The gall bladder stores bile, which breaks down the partially digested foods that, enters the small intestine. Bile has no enzymes but still manages to break down fat into tiny droplets that are ready for faster chemical breakdown. The frog’s stomach is not as complex as a herbivore’s because they have to break down cellulose, which takes a longer time. (Giffard R. & Nat, M 1986)

The Role Catalysts In Chemical Reactions, Their Importance In Industry, Problems And New Developments
... process of catalysis is essential to the modern day manufacturing industry.
Ninety per cent, over a trillion dollars' worth, of manufactured items are
produced with the help of catalysts every year. It is therefore logical that
scientists are constantly searching for new improved catalysts which will
improve efficiency or produce a greater yield.
An acidic catalyst works due its acid nature. Catalysts are strong
acids and readily give up hydrogen ions, or protons: H+. Protons can be released
from hydrated ions, for example H3O+, but more commonly they are released from
ionisable hydroxyl groups (R-OH) where t ...

Bridging Technology And Academe
... to present the potential of technology to faculty just beginning to consider it, as well as open a dialogue with colleagues regarding its utility as a research tool and a heuristic device in the sociology classroom. Three specific questions guide the discussion: 1) Why should sociologists concern themselves with the Internet?; 2) What are the various Internet technologies available to sociologists?, and; 3) How can faculty begin to integrate these technologies into their classrooms and research.
Key words: teaching sociology, information technology, on-line teaching

Mini-Research
... to those particles irrespective of the metal
the electrodes were made of or the kind of gas in the tube. In 1909, RA
Millikan, an American scientist, measured that charge. All electrons are found
to be identical no matter their source or the method of liberating them from
matter. From the values of e/m, and e, the mass of an electron was calculated
to be .00055 amu.
PROTON- Eugeen Goldstein used a Crookes tube with holes in the cathode, and
observed that another kind of ray was emitted from the anode and passed through
the holes. He discovered this in 1886. In 1889, William Wien showed these rays
to b ...

Abstract From: Cloning : Where Do We Draw The Line?
... in-vitro procedure, doctors will insert three to five embryos in hopes
that, at most, one or two will implant" (Elmer-Dewitt 38). And that "a woman
with only one embryo has about a 10% to 20% chance of getting pregnant through
in-vitro fertilization. If that embryo could be cloned and turned into three or
four, thechances of a successful pregnancy would increase significantly"(Elmer-
Dewitt 38).
The experiment the scientists performed is the equivalent of a mother
producing twins. The process has been practiced and almost perfected in
livestock for the past ten years, and some scientists believe that it se ...

Silicon
... electrical resistivities between 10-5 and 107 ohms. Semiconductors can be
crystalline or amorphous. Elemental semiconductors are simple-element
semiconductor materials such as silicon or germanium.
Silicon is the most common semiconductor material used today. It is used
for diodes, transistors, integrated circuits, memories, infrared detection and
lenses, light-emitting diodes (LED), photosensors, strain gages, solar cells,
charge transfer devices, radiation detectors and a variety of other devices.
Silicon belongs to the group IV in the periodic table. It is a grey brittle
material with a diamond cu ...
