| Terms for subject Environment (6310 entries) |
| jēlnafta | crude oil (A comparatively volatile liquid bitumen composed principally of hydrocarbon, with traces of sulphur, nitrogen or oxygen compounds; can be removed from the earth in a liquid state) | |
| jods | iodine (A nonmetallic halogen element; the poisonous, corrosive dark plates or granules are readily sublimed; insoluble in water, soluble in common solvents; used as germicide and antiseptic, in dyes, tinctures, and pharmaceuticals, in engraving lithography, and as a catalyst and analytical reagent) | |
| jonīts | ion exchanger (A permanent insoluble material (usually a synthetic resin) which contains ions that will exchange reversibly with other ions in a surrounding solution. Both cation and anion exchangers are used in water conditioning. The volume of an ion exchanger is measured in cubic liters of exchanger after the exchanger bed has been backwashed and drained, and has settled into place) | |
| jonizējošā radiācija | ionising radiation (Radiation that is capable of energizing atoms sufficiently to remove electrons from them. In this state atoms become more reactive, so that ionizing radiation increases chemical activity and in this way produces biological effects, including effects that involve alterations induced in DNA. X-rays and gamma-rays are the only electromagnetic waves that cause ionization in biological material) | |
| jonosfēra | ionosphere (A region of the earth's atmosphere, extending from about 60 to 1000 kilometers above the earth's surface, in which there is a high concentration of free electrons formed as a result of ionizing radiation entering the atmosphere from space) | |
| jons | ion (An electrically charged atom or group of atoms formed by the loss or gain of one or more electrons) | |
| jonu apmaiņa | ion exchange (The process in which ions are exchanged between a solution and an insoluble solid, usually a resin) | |
| josla tīrumā traktora manevram | headland (farm, A strip of land left at the end of a furrow in a field in order to facilitate the turning of the plough) | |
| joslveida derīgo izrakteņu ieguve | strip mining (Superficial mining, in which the valuable rock is exposed by removal of overburden. Coal, numerous nonmetals and metalliferous ores (iron and copper) are worked in this way. Sinonym: strip mining, opencast mining, openpit mining) | |
| jūra | sea (1. In general, the marine section of the globe as opposed to that of the land. 2. The name given to a body of salt water smaller than an ocean and generally in proximity to a continent) | |
| jūras bioloģija | marine biology (A branch of biology that deals with those living organisms which inhabit the sea) | |
| jūras ekoloģija | marine ecology (An integrative science that studies the basic structural and functional relationships within and among living populations and their physical-chemical environments in marine ecosystems. Marine ecology focuses on specific organisms as well as on particular environments or physical settings) | |
| jūras ekosistēma | marine ecosystem (Any marine environment, from pond to ocean, in which plants and animals interact with the chemical and physical features of the environment) | |
| jūras fauna | marine fauna (Animals which live in the sea) | |
| jūras ģeoloģija | marine geology (That aspect of the study of the ocean that deals specifically with the ocean floor and the ocean-continent border, including submarine relief features, the geochemistry and petrology of the sediments and rocks of the ocean bottom and the influence of seawater and waves on the ocean bottom and its materials) | |
| jūras gultne | sea bed (The bottom of the ocean. Also known as sea floor; sea bottom. The ocean floor is defined as the near-horizontal surface of the ocean basin) | |
| jūras gultnes izmantošana | sea bed exploitation (Marine mineral resources extend far beyond those presently exploited; minerals are derived from two separate types of marine sources: from sedimentary deposits underlying the continental shelves and from inshore deposits on the surface of the continental shelves. By far the most valuable of the mineral resources exploited from marine environments is petroleum. Offshore placer deposits on the surface of the continental shelves yield gold, platinum, and tin. On the floors of the world's oceans manganese nodules are found as a result of pelagic sedimentation or precipitation; they are small, irregular, black to brown, friable, laminated concretionary masses consisting primarily of manganese salts and manganese-oxide minerals) | |
| jūras gultnes resursu ieguve | sea bed mining (The activity or processes involving the extraction of mineral deposits from the surface, or below the surface, of the ocean floor) | |
| jūras inženierija | marine engineering (The design, construction, installation, operation, and maintenance of main power plants, as well as the associated auxiliary machinery and equipment, for the propulsion of ships) | |
| jūras krasts | seashore (The zone of unconsolidated material that extends landward from the low water-line to where there is marked change in material or physiographic form or to the line of permanent vegetation) |
