|
| sufre |
sulphur (A nonmetallic element existing in a crystalline or amorphous form and in four stable isotopes; used as a chemical intermediate and fungicide, and in rubber vulcanization. It is deposited from volcanic vents and fumaroles and also is found in sedimentary rocks, particularly with gypsum and limestone, and associated with salt-domes. Native sulphur is the main source of sulphur for the sulphuric acid industry, followed by sour gas (natural gas containing hydrogen sulphide) and pyrite. Sulphur is an essential plant macronutrient, S) |
|
| sufre dioxido |
sulphur dioxide (Emissions of the gas given off during the burning of fossil fuels in power stations and other boilers. Sulphur dioxide is created because sulphur is an impurity in most coal and oils. When the fuel is burned the hot sulphur reacts with oxygen in the atmosphere to form sulphur dioxide, SO2) |
|
| sufre monoxido |
sulphur monoxide (A gas at ordinary temperatures; produces an orange-red deposit when cooled to temperatures of liquid air; prepared by passing an electric discharge through a mixture of sulfur vapor and sulfur dioxide at low temperature) |
|
| sufre-kontzentrazio |
sulphur concentration (Sulphur content in a solution) |
|
| sufre-oxidoak |
sulphur oxide (An oxide of sulphur, such as sulphur dioxide and sulphur trioxide; they are formed primarily from the combustion of fossil fuels; major air pollutants and cause of damage to the respiratory tract as well as vegetation, SOx) |
|
| suge |
snake (Any reptile of the suborder Ophidia, typically having a scaly cylindrical limbless body, fused eyelids, and a jaw modified for swallowing large prey: includes venomous forms such as cobras and rattlesnakes, large nonvenomous constrictors, and small harmless types such as the grass snake) |
|
| suge |
colubrid (Any snakes of the family of Colubridae, including many harmless snakes, such as the grass snake and whip belonging to the Colubridae) |
|
| sulfato |
sulphate (A salt or ester of sulfuric acid, widely distributed in nature and often found in the atmosphere) |
|
| sulfuro |
sulphide (Any compound that includes one or more sulfur atoms with a more electropositive element, either carbon, metal or some other nonoxygen atom) |
|
| sumendi |
volcano (A vent in the surface of the Earth through which magma and associated gases and ash erupt; also, the form or structure, usually conical, that is produced by the ejected material) |
|
| sumendi-erupzio |
volcanic eruption (The ejection of solid, liquid, or gaseous material from a volcano) |
|
| sumendi-lurralde |
volcanic area (No definition needed) |
|
| suntsitze |
extinction (ecological, 1. The complete disappearance of a species of plant or animal from the planet. 2. Disappearing of animals and plants from the biota) |
|
| superpopulazio |
overpopulation (A population density that exceeds the capacity of the environment to supply the health requirements of the individual organism) |
|
| surfaktante |
surface-active agent (A substance that, when used in small quantities, modifies the surface properties of liquids or solids. A surface-active agent reduces surface tension in a fluid or the interfacial tension between two immiscible fluids, such as oil and water. Surfactants are particularly useful in accomplishing the wetting or penetration of solids by aqueous liquids and serve in the manner of detergent, emulsifying, or dispersing agents. They are more effective than soap in certain situations and are used by conservators for such purposes as cleaning, wetting, and dispersing) |
|
| surtarako egur |
fuel wood (Wood used for heating) |
|
| sustrai |
root (The absorbing and anchoring organ of a vascular plant; it bears neither leaves nor flowers and is usually subterranean) |
|
| sute |
fire (The state of combustion in which inflammable material burns, producing heat, flames and often smoke) |
|
| sute-prebentzio |
fire precaution (Measure, action or installation implemented in advance to avert the possibility of any unexpected and potentially harmful combustion of materials) |
