Contaminated mineral oil may have been associated with calcaneous osteomyelitis in a newborn. Staphylococcus aureus is viable for 1 month as a suspension in mineral oil.

2. Secondary mineral deficiencies are by far the most common of the two. Secondary deficiencies are derived from the consumption of one or more mineral antagonists that interfere with the normal metabolism of another mineral. A simple mineral evaluation of a feedstuff may suggest that adequate trace mineral concentrations are present; however, the presence of a mineral antagonist will decrease ...

It has long been known that ventilation is a costeffective method to lower respirable dust concentrations in all types of mining applications. The National Institute for Occupational Safety and Health has been working on a number of different research techniques that use ventilation as a critical component to lower respirable dust levels at surface and metal/nonmetal operations in the United St...

background: the purpose of this study was to evaluate long-term changes in bone density profile among survivors of childhood acute lymphoblastic leukemia. patients and methods: this was a 5 year prospective study comprised of thirty-one survivors of childhood acute lymphoblastic leukemia with a mean age of 11.8 (4.6) years, who completed therapy at least 1 year previously (according to the all-...

Recently, two-dimensional transition metal dichalcogenides (TMDs) demonstrated their great potential as cost-effective catalysts in hydrogen evolution reaction. Herein, we systematically summarize the existing defect engineering strategies, including intrinsic defects (atomic vacancy and active edges) extrinsic (metal doping, nonmetal hybrid doping), which have been utilized to obtain advanced ...
