slash and burn culture (A traditional farming system that has been used by generations of farmers in tropical forests and the savannah of north and east Africa. It is known to be an ecologically sound form of cultivation, and because the soil is poor in tropical rain forests it is a sustainable method of farming. It is still practised today, primarily in the developing countries. Small areas of bush or forests are cleared and the smaller trees burned. This unlocks the nutrients in the vegetation and gives the soil fertilizer that is easily taken up by plants. A few years later the soil is degraded and the farmer moves on to do the same at another site. The original ground is left fallow for anything up to 20 years so that the forest can regenerate. With the growth in population and in the subsequent need for more farming land to produce food, the method is increasingly being used today to clear large areas of tropical forests for cattle ranching, and in most cases the ground is not left fallow for long enough and, with modern mechanized farming systems, not enough tree stumps or suitable habitats for plant life are left to start the regeneration process) |

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) |
|
| svoveldioksid |
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) |
|
| svovelfjerning |
desulphurisation (The removal of sulphur, as from molten metals or petroleum oil. Sulphur residues in fuels end up as sulphur dioxide when the fuel is burned causing acid rain) |
|
| svovelfjerning fra brennstoff |
desulphurisation of fuel (Removal of sulfur from fossil fuels (or removal of sulfur dioxide from combustion fuel gases) to reduce pollution) |
|
| svovelkonsentrasjon |
sulphur concentration (Sulphur content in a solution) |
|
| svovelmonoksid |
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) |
|
| svoveloksid |
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) |
|
| svovelsyre |
sulphuric acid (A toxic, corrosive, strongly acid, colorless liquid that is miscible with water and dissolves most metals, and melts at 10C; used in industry in the manufacture of chemicals, fertilizers and explosives, and in petroleum refining) |
|
| svulst |
tumour (Any new and abnormal growth, specifically one in which cell multiplication is uncontrolled and progressive) |
|
| sykdom |
disease (A definite pathological process having a characteristic set of signs and symptoms which are detrimental to the well-being of the individual) |
