... would only annihilate with ordinary water, and could safety be kept in (say) an iron container. This is not so: it is the subatomic particles that react so destructively, and their arrangement makes no difference. Scientists at CERN in Geneva are working on a device called the LEAR (low energy anti-proton ring) in an attempt to slow the velocity of the anti-protons to a billionth of their normal speeds. The slowing of the anti-protons and positrons, which normally travel at a velocity of that near the speed of light, is neccesary so that they have a chance of meeting and combining into anti-hydrogen. The problems with research in the field of an ...
... but will also eat rodents and more rarely, fish. If a meal has been particularly big, they may have to spend hours on the ground or a low branch before they can take off again. s are fastidious birds -- after eating, they clean their heads and necks by rubbing them on grass, rocks, or tree branches. s also bathe frequently and spend hours preening and drying their feathers. s were probably never very numerous in North America. The species once ranged along the entire Pacific Coast from British Columbia to Baja California. Fossils have been found as far east as Texas, Florida, and New York. More recently, however, they were confined to a horseshoe-shaped area north ...
... and chemistry. One mistake of Dalton was his belief that atoms were round and hard. This became the primary ambition for scientists after Dalton, to find out the structure of an atom. In 1897, Joseph John Thomson discovered electrons. Using a tube, magnets and charged plates, he sent ray particles through various experiments changing the position of the charged plates. By changing the plates, he discovered he could also change the point at which the particles would hit a florescent screen at the end of the tube. He decided that the ray was made up of particles with a negative charge. He named these particles electrons. This discovery also showed that ato ...
... because of the lack of a good explanation for the movement of the continents. Wegener's theory for the movement of continents was called continental drift. This was not believable at the time because there was no way the continents could move through the rigid ocean floor. During WWII, people started to explore the ocean floor and discovered evidence that would prove Wegener's ideas about land movement. The most interesting feature of the ocean was the ridges running along the ocean floor. It was discovered that earthquakes were abundant along the ridges that let magma flow from them. The magma would flow out these ridges and push the Earth away from it. This ...
... cell junctions. Cell junctions help maintain differences in the internal environment between adjacent cells, help anchor cells together, and allow cells to communicate with one another by passing small molecules from one cell to another. Groups of two or more tissues that function together make up organs. An organ system is a group of organs that work together to carry out major life functions. Eukariotic Cell Structure: Boundaries and Control: Plasma Membrane - The plasma membrane is sometimes called the cell membrane, or the cellular membrane. It is the outermost part of the animal cell, and it's purpose is to enclose the cell, and change shape if needed. T ...
... 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 will result in death (www.cdc.gov). Deaths are rare due to antimicrobial therapy. When anthrax is contracted by inhalation the initial symptoms resemble a common cold. After several days, the symptoms may progress to a severe breathing problems and shock. The inhalation of anthrax spores usually resul ...
... and storing these wastes have been developed so they may no longer be harmful. A very advantageous way of storing radioactive wastes is by a process called 'vitrification'. Vitrification is a semi-continuous process that enables the following operations to be carried out with the same equipment: evaporation of the waste solution mixed with the ------------------------------------------------------------ 1) borosilicate: any of several salts derived from both boric acid and silicic acid and found in certain minerals such as tourmaline. additives necesary for the production of borosilicate glass, calcination and elaboration of the glass. These operations ...
... We all know "that" fire is hot but do we know "why." We also know "that" water is wet but "why" is it wet. These were questions that nobody obtained the answers to but Aristotle was determined to know, and having this type of knowledge would truly earn the title of PAGE 1 Wisdom. Now finding the knowledge and answers would be very difficult but Aristotle believed what better way to obtain this then through the use of science. He knew that everything in science deals with learning using more than just senses. There are always deeper meanings and definitions when pertaining to science. In all types of sciences whether physics, ethics, politics etc. they will dea ...

... of these factors that have to be considered when deciding the location of a Sulfuric Acid plant are: a. Whether there is ready access to raw materials; b. Whether the location is close to major transportation routes; c. Whether there is a suitable work force in the area for plant construction and operation; d. Whether there is sufficient energy resources readily available; e. Whether or not the chemical plant can carry out its operation without any unacceptable damage to the environment. Listed above are the basic deciding factors that govern the location of a plant. The following will explain ...
