Amphibole asbestos (AA) has been detected on the surface of tree bark in forests neighboring an abandoned vermiculite mine near Libby, Montana. In the present study, simulations were performed to assess potential AA exposure associated with United States Department of Agriculture Forest Service (FS) occupational activities. Bark samples were collected prior, and personal breathing zone (PBZ) an...

The fabrication of activated carbon air cathodes for larger-scale microbial fuel cells requires a diffusion layer (DL) that is highly resistant to water leakage, oxygen permeable, and made using inexpensive materials. A hydrophobic polyvinylidene fluoride (PVDF) membrane synthesized using a simple phase inversion process was examined as a low cost ($0.9/m(2)), carbon-free DL that prevented wate...

Sheet metal is one of the most important semi-finished products used in automobiles, domestic appliances, aircraft and other familiar products. Therefore sheet metal forming technology is an important engineering discipline in the area of mechanical engineering. In sheet metal forming, wipe bending process plays a major role in which the sheet metal tries to return to its original shape after r...

To the Editor—Effective disinfection of contaminated surfaces is necessary to prevent transmission of Clostridium difficile spores. In addition to disinfection of rooms after discharge of patients with C. difficile infection (CDI), daily disinfection of surfaces may useful as a measure to decrease healthcare personnel hand contamination by reducing the burden of contamination on frequently touc...

Surfaces in an outpatient setting are exposed to multiple patients b ecome colonized with microorganisms. Copper and alloys containing greater than 60% copper reduce bacterial burdens on solid surfaces by 99.9% within 2 hours.! Copper surfaces have been found to substantially diminish the density of bacte ria to levels below those considered a risk to patients for the acquisition of an infectio...

Abstract Eroders are monotonic cellular automata with a linearly ordered state set that eventually wipe out any finite island of nonzero states. One-dimensional eroders were studied by Gal’perin in the 1970s, who presented simple combinatorial characterization class. The multi-dimensional case has been Toom and others, but no such found. We prove similar for those one-dimensional even presence ...

Introduction Recent work demonstrating reduction of aerosolized contamination via a wipe-down procedure using common veterinary antiseptics offers promise regarding health concerns associated with cross-contamination from working canines to humans. While mechanical can be achieved procedure, the biocidal impact on flora within exterior coat is unknown. Methodology This study assessed bacterial ...
