متن کاملA Novel Technique for Silver Extraction from Silver Sulphide Ore
A novel technique for silver extraction from Ag2S is described. The method utilizes thiosulphate as complexing reagent and the redox reaction between SO2 added as Na2SO3 powder and H2S gas evolved. The parameters of the reaction such as pH, the reaction temperature, the complex equilibrium of Ag ion with thiosulphate and the solubility of Ag2S were investigated. Silver ions, obtained by this me...
متن کاملVancomycin-resistant Staphylococcus aureus isolate from a patient in Pennsylvania.
A vancomycin-resistant Staphylococcus aureus (VRSA) isolate was obtained from a patient in Pennsylvania in September 2002. Species identification was confirmed by standard biochemical tests and analysis of 16S ribosomal DNA, gyrA, and gyrB sequences; all of the results were consistent with the S. aureus identification.

Mound Key, like other archaeological sites along the southwest Gulf Coast, is a large expanse of shell and other anthropogenic sediments. The challenges that these sites pose are largely due to the size and areal extent of the deposits, some of which begin up to a meter be...
