Terms for subject Environment (5171 entries)
karbondioksidavgift carbon dioxide tax (Compulsory charges levied on fuels to reduce the output of carbon dioxide (CO2), which is a colourless and odourless gas substance that is incombustible)
karbonkretsløp carbon cycle (The cycle of carbon in the biosphere, in which plants convert carbon dioxide to organic compounds that are consumed by plants and animals, and the carbon is returned to the biosphere in inorganic form by processes of respiration and decay)
karbonmonoksid carbon monoxide (Colorless, odourless, tasteless, non-corrosive, highly poisonous gas of about the same density as that of air. Very flammable, burning in air with bright blue flame. Although each molecule of CO has one carbon atom and one oxygen atom, it has a shape similar to that of an oxygen molecule (two atoms of oxygen), which is important with regard to it's lethality, CO)
kardiologi cardiology (The study of the heart)
Karibien Caribbean Area (A geographical region bordered on the south by South America and Panama, and on the west by Central America, and consisting of the West Indian, and nearby, islands and the Caribbean Sea, a part of the western Atlantic Ocean)
karplante tracheophyte (A large group of plants characterized by the presence of specialized conducting tissues (xylem and phloem) in the roots, stems, and leaves)
karsinogenitetsprøving carcinogenicity test (Test for assessing if a chemical or physical agent increases the risk of cancer. The three major ways of testing for carcinogens are animals tests, epidemiological studies and bacterial tests)
karstlandskap karst (1. A German rendering of a Serbo-Croat term referring to the terrain created by limestone solution and characterized by a virtual absence of surface drainage, a series of surface hollows, depressions and fissures, collapse structures, and an extensive subterranean drainage network. 2. A type of topography that is formed on limestone, gypsum, and other rocks by dissolution, and that is characterized by sinkholes, caves, and underground drainage. Etymology: German, from the Yugoslavian territory Krs; type locality, a limestone plateau in the Dinaric Alps of northwestern Yugoslavia and northeastern Italy)
kart map (A representation, normally on a flat medium, that displays the physical and political features of a surface area of the earth, showing them in their respective forms, sizes and relationships according to some convention of representation)
kartlegging mapping (The process of making a map of an area; especially the field work necessary for the production of a map)
kartlegging av lav mapping of lichens (Maps of lichens distribution indicating air quality. Fruticose lichens (with branched structures well above the surface) are more susceptible to SO2 damage than foliose lichens (whose leaflike thallus lies nearly flat on surface) and both in turn are more susceptible than crustose lichens (which embed their tissue in the cracks of bark, soil, or rocks). The use of morphological lichen types as indicators of air pollution concentrations is well developed)
kartografi cartography (The making of maps and charts for the purpose of visualizing spatial distributions over various areas of the earth)
kartproduksjon chart (A formal written record of transactions, proceedings, etc., as of a society, committee, or legislative body; act)
Kaspihavet Caspian Sea (No definition needed)
kassert dekk scrap tyre (Recyclable material from discarded motor vehicle tyres)
kassert legemiddel discarded medicinal drug
kastanje chestnut (Any north temperate fagaceous tree of the genus Castanea, such as Castanea sativa, which produce flowers in long catkins and nuts in a prickly bur)
katalysator catalyst (A substance whose presence alters the rate at which a chemical reaction proceeds, but whose own composition remains unchanged by the reaction. Catalysts are usually employed to accelerate reactions(positive catalyst), but retarding (negative) catalysts are also used)
katalyse catalysis (A phenomenon in which a relatively small amount of substance augments the rate of a chemical reaction without itself being consumed)
katalytisk omformer catalytic converter (Catalytic converters are designed to clean up the exhaust fumes from petrol-driven vehicles, which are otherwise the major threat to air quality standards in congested urban streets and on motorways. Converters remove carbon monoxide, the unburned hydrocarbons and the oxides of nitrogen. These compounds are damaging to human health and the environment in a variety of ways. The converter is attached to the vehicle' s exhaust near the engine. Exhaust gases pass through the cellular ceramic substrate, a honeycomb-like filter. While compact, the intricate honeycomb structure provides a surface area of 23.000 square metres. This is coated with a thin layer of platinum, palladium and rhodium metals, which act as catalysts that simulate a reaction to changes in the chemical composition of the gases. Platinum and palladium convert hydrocarbons and carbon monoxide into carbon dioxide and water vapour. Rhodium changes nitrogen oxides and hydrocarbons into nitrogen and water, which are harmless)
