| Terms for subject Environment (5171 entries) |
| habitatødeleggelse | habitat destruction (Destruction of wildlife habitats by increasing pressure for land by fast-growing human populations, pollution and over-exploitation. Whole species or populations of plants and animals have disappeared causing a loss of genetic resource that is not only regrettable from an aesthetic or philosophical point of view but also threatens man's food supply. Habitat loss takes several forms: outright loss of areas used by wild species; degradation, for example, from vegetation removal and erosion, which deprive native species of food, shelter, and breeding areas; and fragmentation, when native species are squeezed onto small patches of undisturbed land surrounded by areas cleared for agriculture and other purposes) | |
| hage | garden (A piece of land next to a house where flowers and other plants are grown and which often has an area of grass) | |
| hage i engelsk stil | English garden (A plot of ground consisting of an orderly and balanced arrangement of masses of flowers, shrubs and trees, following British traditions or style) | |
| hage i fransk stil | French formal garden (No definition needed) | |
| hageavfall | garden waste (Natural organic matter discarded from gardens and yards including leaves, grass clippings, prunings, brush and stumps) | |
| hagebruk | horticulture (The art and science of growing plants) | |
| hagl | hail (Precipitation in the form of balls or irregular lumps of ice, always produced by convective clouds, nearly always cumulonimbus) | |
| haloform | haloform (A haloalkane, containing three halogen atoms, e.g. iodoform, CHI3; a haloform reaction is a reaction to produce haloforms from a ketone. For example, if propanone is treated with bleaching powder, the chlorinated ketone so formed reacts to form chloroform) | |
| halogen | element of group (Any of the elements of the halogen family, consisting of fluorine, chlorine, bromine, iodine, and astatine) | |
| halogenert bifenyl | halogenated biphenyl (Halogen derivatives of biphenyl) | |
| halogenert fenol | halogenated phenol (Halogen derivatives of phenol) | |
| halogenert forbindelse | halogenated compound (A substance containing halogen atoms) | |
| halogenert forurensende stoff | halogenated pollutant (An organic compound bonded with one of the five halogen elements (astatine, bromine, chlorine, fluorine, and iodine). Several of these compounds contribute to reductions in the concentration of ozone in the stratosphere) | |
| halogenert hydrokarbon | halogenated hydrocarbon (One of a group of halogen derivatives of organic hydrogen and carbon containing compounds; the group includes monohalogen compounds (alkyl or aryl halides) and polyhalogen compounds that contain the same or different halogen atoms) | |
| halogenert terfenyl | halogenated terphenyl | |
| halveringstid | half-life (The time required for one-half the atoms of a given amount of radioactive material to undergo radioactive decay) | |
| halvfabrikat | semimanufactured product (Product that has undergone a partial processing and is used as raw material in a successive productive step) | |
| halvleder | semiconductor (A solid crystalline material whose electrical conductivity is intermediate between that of a metal and an insulator and is usually strongly temperature-dependent) | |
| halvmetall | semi-metal (An element having some properties characteristic of metals and others of non-metals. Many metalloids give rise to an amphoteric oxide (e.g. arsenic or antimony) and many are semiconductors) | |
| halvtflytende gjødsel | semi-liquid manure (No definition needed) |
