Terms for subject Environment (6310 entries)
radioaktīvo atkritumu apsaimniekošana radioactive waste management (The total supervision of the production, handling, processing, storage and transport of materials that contain radioactive nuclides and for which use, reuse or recovery are impractical)
radioaktīvo treiseru tehnika radioactive tracer technique
radioelements radioelement (An element that is naturally radioactive)
radionuklīds radionuclide (A nuclide that exhibits radioactivity)
rādītājs rate (The amount of change in some quantity during a time interval divided by the length of the time interval)
rādītājs indicator (Something that provides an indication especially of trends)
rādītspēja demonstrability (No definition needed)
radons radon (A radioactive gaseous element emitted naturally from rocks and minerals where radioactive elements are present. It is released in non-coal mines, e.g. tin, iron, fluorspar, uranium. Radon is an alpha particle emitter as are its decay products and has been indicted as a cause of excessive occurrence of lung cancer in uranium miners. Concern has been expressed at radon levels in some housing usually adjacent to granite rocks or old tin mining regions)
rakšanas vieta excavation site (The location chosen for an excavation, meaning the act or process of removing soil and/or rock materials by digging, blasting, breaking, loading either at the surface or underground)
raksturīga pazīme attribute (A distinctive feature of an object. In mapping and GIS applications, the objects are points, lines, or polygons that represent features such as sampling locations, section corners (points); roads and streams (lines); lakes, forest and soil types (polygons). These attributes can be further divided into classes such as tree species (Douglas-fir and ponderosa pine) for forest types and paved and gravel for road types. Multiple attributes are generally associated with objects that are located on a single map layer)
raktuve mine (An opening or excavation in the earth for extracting minerals)
raktuves aizpildīšana mine filling (Filling of disused mines with soil, crushed stone, or waste materials in order to restore the geological, agricultural and landscape features of the concerned area)
rapsis rape (A Eurasian cruciferous plant, Brassica napus, that is cultivated for its seeds, which yield a useful oil, and as a fodder plant; plant)
rāpulis reptile (A class of terrestrial vertebrates, characterized by the lack of hair, feathers, and mammary glands; the skin is covered with scales, they have a three chambered heart and the pleural and peritoneal cavities are continuous)
rastrs raster (One of the two major types of internal data organization used in GIS. Raster systems superimpose a regular grid over the area of interest and associate each cell-or pixel, to use the image term- with one or more data records. The values associated with each grid cell may represent either real values or any scalar or nominal data values associated with the cell coordinates. Among the strengths of the raster method is its ability to accept data directly from remote sensing systems and to represent transitional information. Raster systems tend to be relatively storage-intensive and this imposes practical limits on the area of coverage, the resolution, or both of these. Capacity constraints are, however, becoming less significant as computer memory and storage become more powerful and as data compression techniques become more readily available)
rastrvektora konversija raster to vector (Methods to convert remotely sensed raster data to vector format. A number of raster-to-vector and vector-to-raster conversion procedures have been developed and introduced to current releases of many GIS packages)
rasu attiecības race relations (The associations, tensions or harmony between two or more groups of people distinguished by history, culture, religion or physique: distinctions erroneously construed as being based on consistent biological differences and as representing, in effect, species of a human genus)
raugs yeast (Many species of unicellular fungi, most of which belong to the Ascomycetes and reproduce by budding. The genus Saccharomyces is used in brewing and winemaking because in low oxygen concentration it produces zymase, an enzyme system that breaks down sugars to alcohol and carbon dioxide. Saccharomyces is also used in bread-making. Some yeasts are used as a source of protein and of vitamins of the B group)
raža yield (The accumulated volume or biomass remaining from gross production after accounting for losses due to respiration during production, herbivory, litterfall, and other factors that decrease the remaining available biomass; agricultural)
raža harvest (The amount or measure of the crop gathered in a season)
