| Terms for subject Environment (5171 entries) |
| alifatisk forbindelse | aliphatic compound (Any organic compound of hydrogen and carbon characterized by a straight chain of the carbon atoms) | |
| alifatisk hydrokarbon | aliphatic hydrocarbon (Hydrocarbons having an open chain of carbon atoms, whether normal or forked, saturated or unsaturated) | |
| alisyklisk forbindelse | 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 hydrokarbon | 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) | |
| alkalijord | 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) | |
| alkalimetall | element of group (Any of the monovalent metals lithium, sodium, potassium, rubidium, caesium, and francium, belonging to group 1A of the periodic table. They are all very reactive and electropositive; alkaline) | |
| alkalisk batteri | 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 jord | 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) | |
| alkan | 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) | |
| alkoholer | 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) | |
| alkylforbindelse | alkyl compound (Compound containing one or more alkyl radicals) | |
| allemannsretten | public access to land (The right or permission for all persons of a community to use government owned geographic areas such as parks, campgrounds and historical sites) | |
| allergi | allergy (A condition of abnormal sensitivity in certain individuals to contact with substances such as proteins, pollens, bacteria, and certain foods. This contact may result in exaggerated physiologic responses such as hay fever, asthma, and in severe enough situations, anaphylactic shock) | |
| allergifremkallende stoff | allergen (Any antigen, such as pollen, a drug, or food, that induces an allergic state in humans or animals) | |
| allmenndannelse | general education (Informal learning or formal instruction with broad application to human existence beyond the domain of any particular subject or discipline, often equated with liberal arts in the university setting and contrasted to courses required for a specific major or program) | |
| allokering | allocation (The assignment or allotment of resources to various uses in accord with a stated goal or policy) | |
| allsidig jordbruk | mixed farming (Type of agriculture based on the combination of crop production and cattle raising) | |
| alpint økosystem | mountain ecosystem (Ecosystems found on high-mountains at low latitudes. Mountain ecosystems are very vulnerable. They are increasingly sensitive to soil erosion, landslide and rapid loss of habitat and genetic diversity. Widespread poverty and an increase in the numbers of mountain inhabitants lead to deforestation, cultivation of marginal lands, excessive livestock grazing, loss of biomass cover and other forms of environmental degradation. Because little is known about mountain ecosystems, Agenda 21 has proposed the establishment of a global mountain database. This is essential for the launch of programmes that would contribute to the sustainable development of mountain ecosystems. The proposals also focus on promoting watershed development and alternative employment for people whose livelihoods are linked to practices that degrade mountains) | |
| alternativ energi | non-conventional energy (Energy that is renewable and ecologically safe, such as tidal power, wind power, etc.) | |
| alternativ teknologi | alternative technology (Technology that, as an alternative to resource-intensive and wasteful industry, aims to utilize resources sparingly, with minimum damage to the environment, at affordable cost and with a possible degree of control over the processes) |
