BOILERS |
|
A boiler is a closed vessel in which water or other fluid is heated under pressure. The steam or hot fluid is then circulated out of the boiler for use in various process or heating applications. A safety valve is required to prevent over pressurisation and possible explosion of a boiler.

BURN MEDICINE |
|
Burns injure the skin layers and can also injure other parts of the body, such as muscles, nerves, lungs, and eyes. Burns are defined as first-, second-, third-, or fourth-degree, depending on how many layers of skin and tissue are burned.

CANCER - ESOPHAGEAL |
|
Esophageal Cancer that forms in tissues lining the esophagus (the muscular tube through which food passes from the throat to the stomach). Two types of esophageal cancer are squamous cell carcinoma (cancer that begins in flat cells lining the esophagus) and adenocarcinoma (cancer that begins in cells that make and release mucus and other fluids).
|
CANCER - PROSTATE |
|
Prostate cancer is a disease in which cancer develops in the prostate, a gland in the male reproductive system. Cancer occurs when cells of the prostate mutate and begin to multiply out of control. These cells may spread (metastasize) from the prostate to other parts of the body, especially the bones and lymph nodes. Prostate cancer may cause pain, difficulty in urinating, erectile dysfunction and other symptoms.
|
CANCER - STOMACH |
|
Stomach cancer (also called gastric cancer) can develop in any part of the stomach and may spread throughout the stomach and to other organs, particularly the esophagus, small intestine. It also may extend through the stomach wall and spread to nearby lymph nodes and to organs such as the liver, pancreas, and colon. Stomach cancer also may spread to distant organs, such as the lungs, the lymph nodes above the collar bone, and the ovaries. Metastasis to the ovary is called a Krukenberg tumor.

CARBON MONOXIDE EMISSIONS |
|
Carbon monoxide, chemical formula CO, is a colorless, odorless, tasteless, flammable and highly toxic gas. It is a major product of the incomplete combustion of carbon and carbon-containing compounds. It is less dense than air under ordinary conditions, however it accumulates on the ground, meaning that if poisoning causes loss of consciousness the amount of carbon monoxide inhaled increases and so fatality is radically increased. It is very slightly soluble in water and burns in air with a characteristic blue flame, producing carbon dioxide; it is a component of producer gas and water gas, which are widely used artificial fuels. It is a reducing agent, removing oxygen from many compounds and is used in the reduction of metals, e.g., iron , from their ores. At high pressures and elevated temperatures it reacts with hydrogen in the presence of a catalyst to form methanol. Carbon monoxide is formed by combustion of carbon in oxygen at high temperatures when there is an excess of carbon. It is also formed with a byproduct oxygen by decomposition of carbon dioxide at very high temperatures (above 2,000 °C). It is present in the exhaust of internal-combustion engines, often the exhaust of automobiles, and is generated in coal stoves, furnaces, and gas appliances that do not get enough air. This may be due to insufficient ventilation or other reasons.

CHEMISTRY |
|
Chemistry (derived from alchemy) is the science of matter at or near the atomic scale. In this pursuit chemistry deals with the properties of such matter, the tranformations of matter and the interactions of matter with other matter and with energy.
|
LEAD |
|
Lead is a chemical element in the periodic table that has the symbol Pb (L. plumbum) and atomic number 82. A soft, heavy, toxic and malleable poor metal, lead is bluish white when freshly cut but tarnishes to dull gray when exposed to air. Lead is used in building construction, lead-acid batteries, bullets and shot, and is part of solder, pewter, and fusible alloys. Lead has the highest atomic number of all stable elements. (But see the article on Bismuth, which has a half life so long it can be considered stable.)

MICROWAVE HEATING |
|
A microwave oven, or microwave, is a kitchen appliance employing microwave radiation primarily to cook or heat food. Microwave ovens have revolutionized cooking since their use became widespread in the 1970s.

POLLUTION |
|
Pollution is the release of environmental contaminants. Carbon monoxide, sulfur dioxide, chlorofluorocarbons (CFCs), and nitrogen oxides produced by industry and motor vehicles are common air pollutants. Sunlight converts nitrogen oxides and hydrocarbons to ozone or smog. Water pollutants may consist of a wide range of organic and inorganic chemicals such as heavy metals, petrochemicals, chloroform, and bacteria. Water pollution may also occur in the form of thermal pollution and dissolved oxygen depletion. Soil contamination is an important aspect of environmental pollution; this phenomenon occurs when chemicals are released by spill or underground storage tank leakage. Among the most significant soil contaminants are hydrocarbons, heavy metals, MTBE, herbicides, pesticides and chlorinated hydrocarbons. The U.S., Russia, China and Japan are the world leaders in air pollution emissions; however, Canada is the number two country on a per capita basis.
