| Terms for subject Environment (5576 entries) |
| 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) | |
| alternativt materiale | alternative material (Materials employed in the place of others which are more dangerous for the environment, such as phosphate substitutes in detergents) | |
| aluminium | aluminium (A light white metal, ductile and malleable, and a good conductor of electricity. It occurs widely in nature in clays and is the third most abundant element in the Earth's crust. It is extracted mainly from bauxite by electrolysis of a molten mixture of purified bauxite and cryolite. The metal and its alloys are used for aircraft, cooking utensils, electrical apparatus, and for many other purposes where its light weight is an advantage. Aluminium became implicated as an environmental health hazard in the 1980s on two counts. Biomedical scientists looking for possible causes of Alzheimer's disease, the premature senility indicated by loss of memory and confusion, found a circumstantial link with aluminium. The theory is a controversial one, Al) | |
| aluminiumboks | aluminium container (A can or box made of aluminium in which material is held or carried) | |
| aluminiuminnhold | aluminium content (Amount of aluminium contained in a solution) | |
| aluminiumoksid | alumina (A natural or synthetic oxide of aluminum widely distributed in nature, often found as a constituent part of clays, feldspars, micas and other minerals, and as a major component of bauxite) | |
| aluminiumsindustri | aluminium industry (A sector of the economy in which an aggregate of commercial enterprises is engaged in the mining and processing of aluminum) | |
| alveole | alveolus (A tiny, thin-walled, capillary-rich sac in the lungs where the exchange of oxygen and carbon dioxide takes place. Also called air sac) | |
| amalgam | amalgam (A solution of a metal in mercury) | |
| Amerika | Americas (The landmasses and islands of North America, South America, Mexico, and Central America included in the Western Hemisphere) | |
| Ames-prøving | Ames test (A bioassay developed by Bruce N. Ames in 1974, performed on bacteria to assess the capability of environmental chemicals to cause mutations) | |
| amfibie | amphibian (A class of vertebrate animals characterized by a moist, glandular skin, gills at some stage of development, and no amnion during the embryonic stage) | |
| amin | amine (One of a class of organic compounds which can be considered to be derived from ammonia by replacement of one or more hydrogens by organic radicals) | |
| aminosyre | amino acid (Organic compounds containing a carboxyl group (-COOH) and an amino group (-NH2). About 30 amino acids are known. They are fundamental constituents of living matter because protein molecules are made up of many amino acid molecules combined together. Amino acids are synthesized by green plants and some bacteria, but some (arginine, histidine, lysine. threonine, methionine, isoleucine, leucine, valine, phenylalanine, tryptophane) cannot be synthesized by animals and therefore are essential constituents of their diet. Proteins from specific plants may lack certain amino acids, so a vegetarian diet must include a wide range of plant products) | |
| ammoniakk | ammonia (A colorless gaseous alkaline compound that is very soluble in water, has a characteristic pungent odour, is lighter than air, and is formed as a result of the decomposition of most nitrogenous organic material, NH3) | |
| ammoniakkdannelse | ammonification (Addition of ammonia or ammonia compounds, especially to the soil) | |
| ammonium | ammonium (The radical NH4+, NH4) |
