Terms for subject Environment (5650 entries)
colour (An attribute of things that results from the light they reflect, transmit, or emit in so far as this light causes a visual sensation that depends on its wavelengths) color
colour composition (A remote-sensing term referring to the process of assigning different colours to different spectral bands. The colour picture formed by this process is called a "colour composite" (a colour image produced through optical combination of multiband images by projection through filters) and is produced by assigning a colour to an image of the Earth's surface recorded in a particular waveband. For a Landsat colour composite, the green waveband is coloured blue, the red waveband is coloured green and the infrared waveband is coloured red. This produces an image closely approximating a false colour photograph. Colour composite images are easier to interpret than separate images recording different wavebands. US national experimental crop inventories are based upon visual interpretation of Landsat colour composites) composició cromàtica
colourimetry (Any technique by which an unknown colour is evaluated in terms of standard colours; the technique may be visual, photoelectric or indirect by means of spectrophotometry) colorimetria
colubrid (Any snakes of the family of Colubridae, including many harmless snakes, such as the grass snake and whip belonging to the Colubridae) colúbrid
combination effect (A combined effect of two or more substances or organisms which is greater than the sum of the individual effect of each) efecte combinat
combined cycle-power station (This type of plant is flexible in response and can be built in the 100-600 MW capacity range. It produces electrical power from both a gas turbine (ca. 1300°C gas inlet temperature), fuelled by natural gas or oil plus a steam turbine supplied with the steam generated by the 500°C exhaust gases from the gas turbine. The thermal efficiency of these stations is ca. 50 per cent compared with a maximum of 40 per cent from steam turbine coal fired power stations. This type of plant can be built in two years compared with six years for a coal-fired station and 10-15 years for nuclear) central elèctrica de cicle combinat
combined sewer system (A sewer intended to serve as a sanitary sewer and a storm sewer, or as an industrial sewer and a storm sewer) sistema de desaigüe col·lectiu
combined transport (Transport in which more than one carrier is used, e.g. road, rail and sea) transport combinat
combined waste water (A mixture of domestic or industrial wastewater and surface runoff) aigua residual combinada
combustibility (The property of a substance of being capable of igniting and burning) combustibilitat
combustion engine (An engine that operates by the energy of combustion of a fuel) motor de combustió
combustion gas (The exhaust gas from a combustion process. It may contain nitrogen oxides, carbon oxides, water vapour, sulfur oxides, particles and many chemical pollutants) gas de combustió
combustion residue (A residual layer of ash on the heat-exchange surfaces of a combustion chamber, resulting from the burning of fuel) residu de la combustió
commercial fishery (Such fisheries belong to one of two groups: one catching demersal (bottom-living) fish, e.g. cod, haddock, plaice, sole; the other catching pelagic (surface-living) fish, e.g. anchovy, tuna, herring) pesca professional
commercial law (The whole body of substantive jurisprudence applicable to the rights, intercourse and relations of persons engaged in commerce, trade or mercantile pursuits) dret mercantil
commercial noise (Noise emitted from commercial activities) soroll comercial i industrial
commercial traffic (The operations and movements related to the transportation and exchange of goods) tràfic comercial
commercial transaction (The conduct or carrying on of trade, business or a financial matter to a conclusion or settlement) acte de comerç
commercial vehicle (Vehicle designed and equipped for the transportation of goods) vehicle comercial
commercialisation (Holding or displaying for sale, offering for sale, selling, delivering or placing on the market in any other form) comercialització
