Epidemiologic studies report associations between particulate air pollution and cardiovascular morbidity and mortality, but the underlying pathophysiologic mechanisms are still unclear. We tested the hypothesis that patients with preexisting coronary heart disease experience changes in the repolarization parameters in association with rising concentrations of air pollution. A prospective panel ...
A nanoporous array anodic titanium-supported co-polymeric ionic liquids (NAAT/PILs) solid-phase microextraction (SPME) fiber was prepared in situ on the titanium wire. NAAT was selected as the substrate, in view of its high surface-to-volume ratio, easy preparation, mechanical stability, and rich titanol groups on its surface which can anchor silica coupling agent containing vinyl and then intr...
Submitted for the DFD05 Meeting of The American Physical Society Hole Dynamics in Polymer Langmuir Films J. ADIN MANN, JR., JAMES ALEXANDER, Case Western Reserve University, ANDREW BERNOFF, Harvey Mudd College, LU ZOU, ELIZABETH MANN, Kent State University — We develop a model for the closing of a gaseous hole in a liquid domain within a two-dimensional fluid layer, a Langmuir film, coupled to ...
It is generally assumed that during denitrification bacteria oxidize organic substances completely to carbon dioxide concomitant with the reduction of nitrate or nitrite to nitrogen and nitrous oxide. This assumption is based upon the early experiments of Gayon and Dupetit (1886) which demonstrated that the ratio of carbon dioxide to nitrogen in denitrifying cultures corresponded to the theoret...
