| galvanització |
galvanisation (The act of coating iron or steel with zinc, either by immersion in a bath of molten zinc or by deposition from a solution of zinc sulphate, to give protection against corrosion) |
|
| gal·linàcia |
gallinacean (The order of birds that includes grouse, ptarmigan, capercaillie, partridges, pheasants, quails, turkeys and peacocks. These are mainly grain-eating, heavy-bodied, ground-nesting birds, capable of only short, rapid flights. The cocks are usually more colourful than the hens) |
|
| garbellatge |
screening (The reduction of the electric field about a nucleus by the space charge of the surrounding electrons) |
|
| garbellatge |
sieving (The size distribution of solid particles on a series of standard sieves of decreasing size, expressed as a weight percent) |
|
| garriga |
garrigue (Mediterranean bush consisting of low evergreen shrubs and abundant herbaceous plants) |
|
| garrofa del desert |
desert locust |
|
| gas |
gas (A substance that continues to occupy in a continuous manner the whole of the space in which it is placed, however large or small this place is mad, the temperature remaining constant) |
|
| gas d'abocador |
landfill gas (Landfill gas is generated in landfill sites by the anaerobic decomposition of domestic refuse (municipal solid waste). It consists of a mixture of gases and is colourless with an offensive odour due to the traces of organosulphur compounds. Aside for its unpleasantness, it is highly dangerous as methane is explosive in concentrations in air between 5 per cent, the Lower Explosive Limit (LEL), and the Upper Explosive Limit (UEL) of 15 per cent. Landfill gas must be controlled at all operational landfill sites, whether actively or passively vented or both especially in the case of deep sites) |
|
| gas d'escapament |
exhaust gas (Offgas produced during combustion processes discharged directly or ultimately to the atmosphere) |
|
| gas d'escapament de vehicle de motor |
motor vehicle exhaust gas (Gases vented to the atmosphere by internal-combustion-engine driven vehicles) |
|
| gas de combustió |
combustion gas (The exhaust gas from a combustion process. It may contain nitrogen oxides, carbon oxides, water vapour, sulfur oxides, particles and many chemical pollutants) |
|
| gas de residus industrials |
industrial waste gas (Waste gases resulting from manufacturing and other industrial processes which may be treated and released, treated and reused or released without treatment) |
|
| gas del tub d'escapament de vehicles |
vehicle exhaust gas (An aeriform fluid of fine particles suspended in air, produced and vented as a byproduct of the operation of wheeled machines or conveyances self-propelled by internal combustion engines) |
|
| gas liquat |
liquefied gas (A gaseous compound or mixture converted to the liquid phase by cooling or compression; examples are liquefied petroleum gas (LPG), liquefied natural gas (LNG), liquid oxygen, and liquid ammonia) |
|
| gas natural |
natural gas (A natural fuel containing methane and hydrocarbons that occurs in certain geologic formations) |
|
| gas residual |
waste gas (Any unusable aeriform fluid, or suspension of fine particles in air, given off by a manufacturing process or the burning of a substance in a enclosed area) |
|
| gasificació |
gasification (1. Any chemical or heat process used to convert a substance to a gas. 2. The production of gaseous fuels by reacting hot carbonaceous materials with air, steam or oxygen. The process takes place at high temperature. The gasification product is a mixture of combustible gases and tar compounds, together with particles and water vapour. Depending on the gasification method, the proportion of components varies, but common to all the processes is that the gas has to be purified before it can be used directly in a gas engine or a gas turbine) |
|
| gasificació del carbó |
coal gasification (Process of conversion of coal to a gaseous product which is used as fuel in electric power stations) |
|
| gasoducte |
gas pipeline (A long pipe, especially underground, used to transport gas over long distances) |
|
| gasohol |
gasohol (A mixture of 80% or 90% petrol with 20% or 10% ethyl alcohol, for use as a fuel in internal combustion engines) |
