Up to 0.4 mM 1,3-dimethylbenzene (m-xylene) was rapidly mineralized in a laboratory aquifer column operated in the absence of molecular oxygen with nitrate as an electron acceptor. Under continuous flow conditions, the degradation rate constant (pseudo-first order) was >0.45 h. Based on a carbon mass balance with [ring-C]m-xylene and a calculation of the electron balance, m-xylene was shown to ...

The purpose of the present study is to evaluate mass fractions group noble metals (gold, silver, platinum, ruthenium, osmium, palladium, iridium, rhodium) in ores and host rocks Pioneer deposit (the Upper Amur Region, Russia) determine their migration activity hydrochemical classification ore by sizes. object primary oxidized ores, as well hosting this mineralization. employs method quantitativ...

The Huoluotai Cu (Mo) deposit is a recently discovered porphyry in the northern Great Xing’an Range, NE China. Fluid inclusion (FI) micro-thermometry results and C–H–O–S–Pb isotope compositions of are presented this study. ore-forming process consists sulfide-barren quartz stage (I), + chalcopyrite ± pyrite molybdenite (II), polymetallic sulfide (III), calcite fluorite (IV). mineralization occu...

Supraspinatus strain Dogs with strain of the supraspinatus tendon present with a chronic foreleg lameness; some dogs will exhibit periods of non-weight bearing lameness. Although uncommon, any age or breed of dog can be afflicted; however, the condition is seen more in large breeds of dogs (Labrador, Rottweiler). Radiographic views should include standard lateral projections of both shoulders. ...
