... his he needed to use another line to connect his phone and the phone of his friend . So imagine that he has X friends , he would need X(X-1)/2 lines and X-1 phones , that was impossible so the need of networks come up . The network first developed for the need of the voice communication but after the appearance of data communications need the same network was used . From the time that electricity and electronics had developed there was rapidly changes at the section of the communications . After the decade of the 1950 the computers started developing , and the communications started playing an important role in peoples life . Also the evolution of the voice commun ...
... if not properly used. Pest problems are not new; in fact, they have been around as long as agriculture itself. But the pest pressure faced by farmers is now as great as it ever was: the world's fast-growing human population needs to be fed from an always shrinking base of agricultural land, and the substantial damage that can be inflicted by pests (e.g. insects, diseases, weeds, rodents, birds) on crops is the margin between a good harvest and a bad one. Pests can reduce the quality of a harvest as well as its quantity. Since the quality of food is increasingly important to consumers, a pest could reduce the value of a crop or make it unsaleable. But it is impo ...
... slam into each other in a chaotic ceremonial dance. The purpose of the dance is to cause and endure as much physical pain as possible. The dance eventually gets so extreme that a young man in the crowd snaps his neck and dies. The man does not stop his ravings and the crowd doesn't stop their dance. Instead the man becomes entirely deranged, screaming at the body of the young man that he is now going to hell where he rot in flames of agony for eternity. The crowd roars and the man laughs. What do you suppose would now transpire? At the very least the man and the crowd would be arrested. More than likely there would be several charges of third degre ...
... he is making a hypothesis on a distinctive type of concept. The conclusions that Galileo made relate directly to the work in physics for which he is so well known. His conclusions put emphasis on shapes, numbers, and motion which are all properties that lend themselves to support through "reasoning back and forth between theory and experiment." I feel that Galileo's argument is a valid one because it explains relations in nature and the physical world through mathematical analysis. This allows him to define a world outside of human existence that can be logically calculated and explained. His view describes the world in which living creatures live and not co ...
... of ATP (adenosine triphosphate) to ADP (adenosinediphosphate). When all the ATP is broken down, phosphate in the muscle donates a phosphate group to ADP, and further energy reactions can occur. monohydrate is a precursor to phosphate. By supplementing with CM, CP levels in muscle apparently are maximized, and more muscular work can occur, since there are greater energy reserves to use. Approximately 95% of the body's supply is found in the skeletal muscles. The remaining 5% are scattered throughout the rest of the body, with the highest concentrations in the heart, brain and testes. A skeletal muscle itself does not produce , bu ...
... sulphide. Thallium was originally used to help treat ringworm and many other skin infections. It was then limited because of the narrow margin between the benefits and its health risks. Thallium bromide-iodide crystals are still used as infrared detectors. Thallium sulphate used to be widely used as a pesticide and an ant killer. It was odorless and tasteless and worked well, but it was found to be too toxic. Thallium slats which burn with a bright green flame are used in flares and rockets. Thallium is the 60th most abundant element in the Earth’s crust. There are 3.6 parts of Thallium in every million parts of the Earth’s crust. Thallium compounds a ...
... from the soil, many methods have been developed in order to find ways to improve or change the soil to suit the plant's needs. Soil, in science as well as in common gardening, must undergo detailed inspection, to detect such things as the pH of the soil. A soil with a pH above 7.0 is called an alkaline soil, and will commonly kill plants. Mineral content, as mentioned above, is also a concern, and must be clearly monitored. After inspection, it is common for minor organic materials outside fertilizers to be applied, such as peat moss, ground bark, or leaf mold. It is after these steps that fertilization must occur, leading to a debate which has plagued ga ...
... reduced by more than 40 per cent from 1980 to 1993. In the same period, Norway's emissions were reduced by more than 70 per cent. · As a result of higher precipitation in recent years, sulphur deposition has not dropped as much as might be expected from the reductions in emissions. · Estimates of how much pollution the environment can absorb without damage are called critical loads. · Sulphur, like nitrogen, is essential to all animals and plants. The natural sulphur cycle includes volcanic emissions, sulphate in sea salts, and sulphur compounds produced by marine organisms. On a global basis, emissions from such sources are of about the same order of ...
... moving neutrons created by the splitting atoms, it repels the slower moving protons and electrons, then gathers the neutrons and pulls them inward. While all these atoms are flying about they smash together then split many of many times, this is when the reactor grabs and pulls in the frictional energy to be processed into electrical watts. This usually causes heat or thermal energy, this must be removed by some kind of a coolant. Most power plants use water or another type of liquid based formula. these coolants are always base related, never acidic. Very few use gas related coolants in there reactors, these are known as thermal reactor based power plants. A ...
... article I had recently read about the dangers of scientific some advancements. Coincidentally, the article was called, “Brave New Worlds”. It stated that “Developments in the field of genetics offer the possibility of bringing all life processes under control. We must step carefully into this vast new field of science with the understanding that putting a patent on the melanoma gene or the baldness gene for that matter is simply playing God in a potentially dangerous way.” (Appleyard, Bryan, Jan 98, Smithsonian) These are only a few examples of scientific developments that in my mind raise the question: in science? Mr. Appleyard could not have been more ...
