[1] We use observations of the mass-independent oxygen isotopic composition (DO) of sulfate in the marine boundary layer (MBL) to quantify the sulfate source from aqueous SO2 (S(IV)) oxidation by O3 in alkaline sea-salt aerosols. Oxidation by O3 imparts a large DO signature to the resulting sulfate (8.8%) relative to oxidation by H2O2 (0.9%) or by OH or O2 (0%). Ship data from two Indian Ocean ...

Sulfur (S) is an important nutrient for plant growth and crop yield. In the northern U.S. Corn Belt, a decrease in atmospheric S deposition increase grain harvest have increased frequency of deficiency corn (Zea mays L.) soybean [Glycine max (L.) Merr.]. Nevertheless, remains difficult to predict owing complex interactions between production plant-available sulfate-S from soil organic matter (S...

Background. Neuropilin-1 (NRP-1) is a multidomain membrane protein with soluble isoforms interacting with a complex network of other membrane receptors, their respective ligands and heparan sulfate (HS). It is involved in the development of vasculature, neural patterning, immunological responses and pathological angiogenesis. Methods. We have characterised the binding of a Fc fusion of rat NRP-...

Today, due to the natural decline of oil exploitation, the use of methods of oil recovery, has made significant progress. However, these methods are accompanied by accumulation and deposition of mineral deposits in oil field installations. In the present study, aqueous solutions, strontium sulfate, barium sulfate, manganese sulfate and nickel sulfate are studied, in terms of EUNIQUAC model and ...
