Carbon Monoxide
Carbon monoxide (chemical formula CO) is a poisonous, flammable gas that is colorless, odorless, tasteless, and slightly less dense than air. Carbon monoxide consists of one carbon atom and one oxygen atom connected by a triple bond. It is the simplest oxocarbon, carbon oxide. In coordination complexes, the carbon monoxide ligand is called ''metal carbonyl, carbonyl''. It is a key ingredient in many processes in industrial chemistry. The most common source of carbon monoxide is the partial combustion of carbon-containing compounds. Numerous environmental and biological sources generate carbon monoxide. In industry, carbon monoxide is important in the production of many compounds, including drugs, fragrances, and fuels. Indoors CO is one of the most acutely toxic contaminants affecting indoor air quality. CO may be emitted from tobacco smoke and generated from malfunctioning fuel-burning stoves (wood, kerosene, natural gas, propane) and fuel-burning heating systems (wood, oil, n ...

Continental Airlines

Continental started out as one of the smaller carriers in the United States, known for its limited operations under the regulated era that provided very fine, almost fancy, service against the larger majors in important point-to-point markets, the largest of which was Chicago/Los Angeles. However, deregulation in 1978 changed the competitive landscape and realities, as noted by Smithsonian Airline Historian R. E. G. Davies, "Unfortunately, the policies that had been successful for more than forty years under [Robert] Six's cavalier style of management were suddenly laid bare as the cold winds of airline deregulation changed all the rules—specifically, the balance between revenues and expenditures." In 1981, Texas International Airlines acquired ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Conscientious Objector
A conscientious objector is an "individual who has claimed the right to refuse to perform military service" on the grounds of freedom of conscience or religion. The term has also been extended to objecting to working for the military–industrial complex due to a crisis of conscience. In some countries, conscientious objectors are assigned to an alternative civilian service as a substitute for conscription or military service. A number of organizations around the world celebrate the principle on May 15 as International Conscientious Objection Day. On March 8, 1995, the United Nations Commission on Human Rights resolution 1995/83 stated that "persons performing military service should not be excluded from the right to have conscientious objections to military service". This was re-affirmed on April 22, 1998, when resolution 1998/77 recognized that "persons lreadyperforming military service may ''develop'' conscientious objections".
