Exempel på sulfur

• The taxa analyzed include representatives from cyanobacteria, green sulfur, green non-sulfur and purple bacteria.

• Glucosinolates consist of a glucose molecule, a sulfur moiety, and a side chain, the composition of which determines their properties.

• These differences are also consistent model predictions of sulfur isotope fractionations produced by biosynthetic networks.

• They contain clusters of iron and sulfur atoms with variable nuclearity and complexity.

• This was due to the use of wettable and dusting sulfur (a miticide) in organic fields, which was the only pesticide used by organic growers.

• Most of these organisms are anaerobes which use inorganic redox reactions of molecular hydrogen, carbon dioxide, iron-, nitrogen-, or sulfur compounds as energy sources.

• Figure 1a shows that the relationship between sulfur dioxide concentrations and freedoms is nearly linear.

• They contribute 16 per cent of all particulate matter pollution, and 43 per cent of all sulfur dioxide.

• Sodium and sulfur are very soluble, and therefore mobile, while calcium is less soluble and mobile.

• However, we find unexpected complexity in the sulfur cycle in a chemoautotrophically-based cave ecosystem.

• In 1979, an air quality standard for sulfur dioxide was established.

• The precipitated metals can subsequently be involved in reactions of the sulfur cycle.

• This classification is based on the sulfur content because this is the element that makes a fuel more or less contaminating.

• There are, however, few studies about the effect of backwash on sulfur packed-bed reactors.

• On the other hand, performance of the baghouse is not sensitive to the sulfur content of the coal.
