Sorption to iron (Fe) minerals determines the fate of toxic metalloid arsenic (As) in many subsurface environments. Recently, thiolated As species have been shown dominate aqueous speciation under a range environmentally relevant conditions, thus highlighting need for quantitative understanding their sorption behavior. We conducted batch experiments measure time-dependent two S-substituted arsenate species, mono- and tetrathioarsenate, compared it arsenite arsenate, suspensions containing...
Sulfur isotope fractionation during dissimilatory sulfate reduction by two strains of the thermophilic archaeon Archaeoglobus fulgidus (strains VC-16 and Z) was explored over entire temperature range growth. The optimal cell-specific rate (14 fmol cell(-1) h(-1)) found at 82-84 degrees C but growth measured as low 54 C. ranged between 0.52 per thousand 27 thousand, with largest fractionations were intermediate temperatures smallest lowest highest temperatures. There an inverse relationship...
Integrated circuits (ICs) are fabricated by a sophisticated series of process steps. A complete education in the field semiconductor processing requires thorough understanding fabrication process. However, due to space, equipment, and budget constraints, hands-on microelectronics instruction is usually limited, despite high student demand. To alleviate these resource limitations enhance educational experience, an environment which simulates IC physical laboratory using interactive multimedia...
An opportunity in single-parenthood for women is the enhanced sense of competence. Yet, a well-documented hazard depressed well-being. Remarriage may reverse these outcomes. This study compared two matched samples divorced and remarried mothers. Contrary to research hypothesis, mothers had both higher competence well-being than mothers, which was significantly related feelings satisfaction areas love, community, homemaking. There were no differences other areas, such as work or parenting....
