| Terms for subject Environment (5171 entries) |
| didaktikk | didactics (The art or science of teaching) | |
| diesel | diesel fuel (Heavy oil residue used as fuel for certain types of diesel engines) | |
| dieselmotor | diesel engine (An internal combustion engine operating on a thermodynamic cycle in which the ratio of compression of the air charge is sufficiently high to ignite the fuel subsequently injected into the combustion chamber) | |
| differensiering | differentiation (The development of cells so that they are capable of performing specialized functions in the organs and tissues of the organisms to which they belong) | |
| diffus forurensning | diffuse pollution (Pollution from widespread activities with no one discrete source, e.g. acid rain, pesticides, urban run-off etc.) | |
| diffus kilde | diffuse source (Pollution which arises from various activities with no discrete source) | |
| diffusjon | diffusion (The spontaneous movement and scattering of particles (atoms and molecules), of liquid, gases, and solids) | |
| digital bildebehandlingsteknikk | digital image processing technique (Techniques employed in the calibration of image data, the correction or reduction of errors occurring during capture or transmission of the data and in various types of image enhancement-operations which increase the ability of the analyst to recognize features of interest) | |
| digital terrengmodell | digital land model (A representation of a surface's topography stored in a numerical format. Each pixel has been assigned coordinates and an altitude) | |
| digitalisering | digitizing (The process of converting data to a form used in computers, transmitted or stored with digital technology and expressed as a string of 0's and 1's) | |
| digitalt GIS-format | GIS digital format (The digital form of data collected by remote sensing) | |
| digitalt GIS-system | GIS digital system (An organized collection of computer hardware, software, geographic data, and personnel designed to efficiently capture, store, update, manipulate, analyze, and display all forms of geographically referenced information that can be drawn from different sources, both statistical and mapped) | |
| dike | dyke (An artificial wall, embankment, ridge, or mound, usually of earth or rock fill, built around a relatively flat, low-lying area to protect it from flooding; a levee. A dyke may be also be constructed on the shore or border of a lake to prevent inflow of undesirable water) | |
| dikeforsterking | dyke reinforcement (The addition of material to strengthen the structure of the dykes) | |
| dikelandskap | polder (A generally fertile tract of flat, low-lying land (as in Netherlands and Belgium) reclaimed and protected from the sea, a lake, a river, or other body of water by the use of embankments, dikes, dams, or levees. The term is usually reserved for coastal areas that are at or below sea level and that are constantly protected by an organized system of maintenance and defense) | |
| dinitrogenoksid | nitrogen monoxide (A colourless gas, soluble in water, ethanol and ether. It is formed in many reactions involving the reduction of nitric acid, but more convenient reactions for the preparation of reasonably pure NO are reactions of sodium nitrite, sulphuric acid, etc.) | |
| dinoflagellatoppblomstring | red tide (Sea water which is covered or discoloured by the sudden growth of algal bloom or by a great increase in single-celled organisms, dinoflagellates. Red tides are often fatal to many forms of marine life and, in some cases, can result in human deaths because the dinoflagellates are eaten by clams and mussels which concentrate the paralysing toxins which they produce) | |
| dioksin | dioxin (A by-product formed during the preparation of the herbicide 2, 4, 5-T, and sometimes produced by the incineration of chlorinated organic compounds. It may also occur naturally and is distributed widely in the environment, except locally in extremely low concentrations. Substantial amounts were released by the industrial accident of Seveso in 1976) | |
| direkte induser | direct discharger (Factories and industrial concerns which do not discharge their sewage directly into public sewers, but directly into a waterway) | |
| direktekoplet tjeneste | on-line service (Service providing an active connection with a communications network) |
