| Terms for subject Environment (6279 entries) |
| rašeliniště | peat land | |
| rašeliniště | peatland | |
| rašeliniště | bog (A commonly used term in Scotland and Ireland for a stretch waterlogged, spongy ground, chiefly composed of decaying vegetable matter, especially of rushes, cotton grass, and sphagnum moss) | |
| rastr | 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) | |
| rastr na vektor | 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) | |
| řasy | alga (Simple, green, aquatic plants without stems, roots or leaves. They are among the microscopic organisms that form the start of the food chain. Algae are found floating in the sea and fresh water, but they also grow on the surface of damp walls, rocks, the bark of trees and on soil. They contain chlorophyll and other pigments that let them grow by photosynthesis. On land, algae can be useful in improving the fertility of soil by nitrogen fixation) | |
| řasy žlutohnědé | chrysophyta (The golden-brown and orange-yellow algae; a diverse group of microscopically small algae which inhabit fresh and salt water, many being planktonic. They contain carotenoid pigments and may be unicellular, colonial, filamentous or amoeboid) | |
| reakce chemická | chemical reaction (A change in which a substance is transformed into one or more new substances) | |
| reakce fotochemická | photochemical reaction (Chemical reaction which is initiated by light of a specific wavelength. In an environmental context an example is the potential action of ultraviolet light on CFCs which may bring about the detrimental degradation of the ozone layer. Photochemical reactions initiate the process of photosynthesis in which plants convert carbon dioxide into sugars, which are incorporated into cell materials) | |
| reakce jaderná | nuclear reaction (A reaction involving a change in an atomic nucleus, such as fission, fusion, neutron capture, or radioactive decay, as distinct from a chemical reaction, which is limited to changes in the electron structure surrounding the nucleus) | |
| reakce látky znečišťující | pollutant behaviour | |
| reaktivita látek | behaviour of substances (Reactivity of a compound depending on the structure of the molecules) | |
| reaktor | reactor (A device that introduces either inductive or capacitive reactance into a circuit, such as a coil or capacitor) | |
| reaktor jaderný | nuclear reactor (Device which creates heat and energy by starting and controlling atomic fission) | |
| reaktor rychlý | fast reactor (Nuclear reactor which produces more fissile material than it consumes, using fast-moving neutrons and making plutonium-239 from uranium-238, thereby increasing the reactor's efficiency) | |
| realizovatelnost ekonomická | economic viability (Capability of developing and surviving as a relatively independent social, economic or political unit) | |
| řeč | speech (An address or form of oral communication in which a speaker makes his thoughts and emotions known before an audience, often for a given purpose) | |
| recyklace | recycling (A resource recovery method involving the collection and treatment of a waste product for use as raw material in the manufacture of the same or a similar product) | |
| recyklace látek reziduálních | residue recycling (Recycling of material or energy which is left over or wasted in industrial processes and other human activities. Examples include waste heat and gaseous pollutants from electricity generation, slag from metal-ore refining, and garbage. A residual becomes an output or input when a technological advance creates economic opportunities for the waste) | |
| recyklace odpadů | waste recycling (A method of recovering wastes as resources which includes the collection, and often involving the treatment, of waste products for use as a replacement of all or part of the raw material in a manufacturing process) |
