| Terms for subject Environment (6528 entries) |
| radionuklidas | radionuclide (A nuclide that exhibits radioactivity) | |
| radonas | 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) | |
| rafinavimas | refining (The processing of raw material to remove impurities) | |
| raguotis | bovid (Any animal belonging to the Bovidae family) | |
| raidos koeficientas | evolution coefficient | |
| Ramiojo vandenyno pietinė dalis | South Pacific Ocean (An ocean south of the equator between Southeast Asia and Australia in the Eastern hemisphere and South America in the Western hemisphere, extending southward to the Antarctic region, including the Tasman and Coral seas and numerous islands, such as Galapagos, Solomon, Easter, Samoa, Fiji and Tonga islands, and also New Zealand and its islands) | |
| Ramiojo vandenyno regiono aplinkos apsaugos programa | Pacific Regional Environment Programme | |
| Ramiojo vandenyno regiono aplinkos apsaugos programa | South Pacific Regional Environment Programme | |
| Ramiojo vandenyno šiaurinė dalis | North Pacific Ocean (An ocean north of the equator between the eastern coast of Asia and the western coasts of the Americas, extending northward to the arctic region, with principal arms including the Gulf of Alaska, the Sea of Okhotsk, the Sea of Japan and the Bering, Yellow, East China, South China and Philippine seas, and islands including the Aleutian, Midway, Marshall and Hawaiian islands, the Japanese island arc and the Malay Archipelago) | |
| rankdarbiai | handicraft (A particular skill performed with the hands) | |
| rankdarbių verslas | handicraft business (The profession, commercial firm or trade involving the production and distribution of articles that are made through the skilled use of one's hands) | |
| rapsas | rape (A Eurasian cruciferous plant, Brassica napus, that is cultivated for its seeds, which yield a useful oil, and as a fodder plant; plant) | |
| rasiniai santykiai | 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) | |
| rastrinio formato pakeitimas į vektorinį | 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) | |
| raudonasis sąrašas | red list (The series of publications produced by the International Union for the Conservation of Nature and Natural Resources (IUCN). They provide an inventory on the threat to rare plants and animal species. Information includes status, geographical distribution, population size, habitat and breeding rate. The books also contain the conservation measures, if any, that have been taken to protect the species. There are five categories of rarity status: endangered species; vulnerable organisms, which are those unlikely to adapt to major environmental effects; rare organisms, which are those at risk because there are few of them in the world, such as plants which only grow on mountain peaks or on islands; out of danger species, which were formerly in the above categories, but have had the threat removed because of conservation actions; and indeterminate species, which are the plants and animals probably at risk, although not enough is known about them to assess their status) | |
| raumenų sistema | muscular system (The muscle cells, tissues, and organs that effect movement in all vertebrates) | |
| reabilitacija | rehabilitation (A conservation measure involving the correction of past abuses that have impaired the productivity of the resources base) | |
| reakcijų kinetika | reaction kinetics (That branch of physical chemistry concerned with the mechanisms and rates of chemical reactions) | |
| reaktoriaus sauga | reactor safety (Those studies and activities that seek to minimise the risk of a nuclear reactor accident) | |
| reaktorius | reactor (A device that introduces either inductive or capacitive reactance into a circuit, such as a coil or capacitor) |
