aircraft (Any structure, machine, or contrivance, especially a vehicle, designed to be supported by the air, either by the dynamic action of the air upon the surfaces of the structure or object or by its own buoyancy) |

|
aircraft engine emission (The formation and discharge of gaseous and particulate pollutants into the environment, especially the stratosphere, chiefly from airplanes, helicopters and other high-altitude aircrafts) |
utslipp fra fly |
|
aircraft noise (Effective sound output of the various sources of noise associated with aircraft operation, such as propeller and engine exhaust, jet noise, and sonic boom) |
flystøy |
|
airport (A landing and taking-off area for civil aircraft, usually with surfaced runways and aircraft maintenance and passenger facilities) |

|
airspace planning (The activity of organizing or preparing for transportation through the atmosphere above earth's surface) |

|
alcohol (A group of organic chemical compounds composed of carbon, hydrogen, and oxygen. The molecules in the series vary in chain length and are composed of a hydrocarbon plus a hydroxyl group. Alcohol includes methanol and ethanol) |
alkoholer |
|
alga (Simple, green, aquatic plants without stems, roots or leaves. They are among the microscopic organisms that form the start of the food chain. Algae are found floating in the sea and fresh water, but they also grow on the surface of damp walls, rocks, the bark of trees and on soil. They contain chlorophyll and other pigments that let them grow by photosynthesis. On land, algae can be useful in improving the fertility of soil by nitrogen fixation) |
alge |
|
algal bloom (Excessive and rapid growth of algae and other aquatic plants when they are stimulated to grow too quickly by pollution. It takes place when there are too many nutrients in the water and is aggravated when accompanied by a rise in temperature. Although the algae grow quickly they soon die because they have swallowed up all the water's nutrients. As they decompose they tend to rise to the surface and form a green slime. Algal bloom have increased because higher levels of nitrogen and phosphates from agricultural areas have leached from the fields into water courses) |
algeoppblomstring |
|
algicide (Any substance or chemical applied to kill or control algal growth) |
algemiddel |
|
alicyclic compound (Any substance composed of two or more unlike atoms held together by chemical bonds characterized by straight-chained, branched or cyclic properties) |
alisyklisk forbindelse |
|
alicyclic hydrocarbon (A class of organic compounds containing only carbon and hydrogen atoms joined to form one or more rings and having the properties of both aliphatic and cyclic substances) |
alisyklisk hydrokarbon |
|
alignment (The selection and detailed layout of public transport routes in the light of construction, operation, service, technology, and economic criteria) |
trasering |
|
aliphatic compound (Any organic compound of hydrogen and carbon characterized by a straight chain of the carbon atoms) |
alifatisk forbindelse |
|
aliphatic hydrocarbon (Hydrocarbons having an open chain of carbon atoms, whether normal or forked, saturated or unsaturated) |
alifatisk hydrokarbon |
|
alkali land (Any geomorphic area, often a level lake-like plain, with soil containing a high percentage of mineral salts, located especially in arid regions) |
alkalisk jord |
|
alkali soil (Soil that contains sufficient exchangeable sodium to interfere with water penetration and crop growth, either with or without appreciable quantities of soluble salts) |
alkalijord |
|
alkaline battery (A primary cell that uses an alkaline electrolyte, usually potassium hydroxide, and delivers about 1.5 volts at much higher current rates than the common carbon-zinc cell. Also known as alkaline-manganese cell) |
alkalisk batteri |
|
alkane (Paraffins. A homologous series of saturated hydrocarbons having the general formula CnH2n+2. Their systematic names end in -ane. They are chemically inert, stable, and flammable. The first four members of the series (methane, ethane, propane, butane) are gases at ordinary temperatures; the next eleven are liquids, and form the main constituents of paraffin oil; the higher members are solids. Paraffin waxs consists mainly of higher alkanes) |
