Low-temperature C-S bond cleavage at low exposure ultimately results in nonsele...

More Information www.agilent.com/chem/icpms Introduction Biogas is the term used to describe the mixture of methane, carbon dioxide, nitrogen and other components resulting from the anaerobic fermentation of a variety of biodegradable materials including animal waste, domestic sewage sludge and municipal landfill waste. Because of its methane content (40-75%), biogas can be used as a substitute...

Why is it that different organisms do so many different things with sulfur?  Sulfur exists in many different oxidation states  Reduced sulfur is required for many biomolecules  Sulfur forms can serve as an electron sources or as electron acceptors  Oxidation states of sulfur  Sulfur assimilation in bacteria and yeasts  Sulfur-containing biomolecules  Sulfide Oxidation  Sulfate Reduction...

in order to study the effect of different levels of nitrogen and sulfur fertilizers on yield, yield components, content of some elements, qualitative and quantitative traits of spring safflower (serin cv.) an experiment was conducted at agriculture and natural resource research station of ardabil in 2008. this experiment was carried out in factorial experiment in completely randomized block des...

line wb73-6 (trompillo, cmb74a-432-25b-1y-ib-1y-ob) was first introduced in iran through a nursery received from cimmyt in 1989. it was selected in a preliminary experiment in zabol research station among the genotypes of ibon in 1990. in other preliminary and advanced yield trails carried out in zabol and other stations in southern provinces of iran with warm climate in 1991-1997, line wb73-6 ...
