The sulfur cycle is the collection of processes by which sulfur moves to and from minerals (including the waterways) and living systems.

Often the elemental sulfur is stored as polysulfides.

The combination of high subsidies, historically declining catches, high fuel costs and other factors make longlining unsustainable, inefficient and unprofitable to most fishers.

This furnace operates at a high temperature by using regenerative preheating of fuel and air for combustion.

Nitrogen, phosphorus, and sulfur are also needed in relatively large quantities.

Oxidation of hydrogen sulfide produces elemental sulfur (S8), oxidation state 0.

Vegetal Fuel and charcoal production was of about 15,022 m³, which meant a very high consumption of forest resources.

The exposure to the sulfur weakened the monster but also preserved him.

Brazil is leading the way with a high consumption level of ethanol and the great success of flexi fuel cars.

The wackiest plan and I'm not making this up would put what is essentially a garden hose 18 and a half miles high into the sky, suspended by balloons, to spew sulfur dioxide.

Several factors contributed to the crisis, including high oil prices, high demand for crops from the bio fuel sector, falling global stockpiles of food commodities, and lower cereal production.
