The literature suggests that there is a need for measuring public health informatics (PHI) competency to further understand whether current educational modules and modalities meet the needs of PHI practitioners and researchers to perform their jobs more effectively, particularly for mid-tier practitioners that constitute the majority of public health(More)
A comprehensive gas puff capability is being developed on the Z pulsed power generator. We describe the methodology employed for developing a gas puff load on Z, which combines characterization and modeling of the neutral gas mass flow from a supersonic nozzle, numerical modeling of the implosion of this mass profile, and experimental evaluation of these(More)
We show how the “finite Quot scheme method” applied to Le Potier’s strange duality on del Pezzo surfaces leads to conjectures (valid for all smooth complex projective surfaces) relating two sets of universal power series on Hilbert schemes of points on surfaces: those for top Chern classes of tautological sheaves, and those for Euler characteristics of line(More)
The objective of this study was to determine whether prostaglandin E1 (PGE1) or prostaglandin E2 (PGE2) prevents premature luteolysis in ewes when progesterone is given during the first 6 days of the estrous cycle. Progesterone (3 mg in oil, im) given twice daily from Days 1 to 6 (estrus = Day 0) in ewes decreased (P < 0.05) luteal weights on Day 10(More)
The objective of this study was to determine whether PGE1 or PGE2 prevents a premature luteolysis when oxytocin is given on Days 1 to 6 of the ovine estrous cycle. Oxytocin given into the jugular vein every 8 hours on Days 1 to 6 postestrus in ewes decreased (P ≤ 0.05) luteal weights on Day 8 postestrus. Plasma progesterone differed (P ≤ 0.05) among the(More)
Natural Resources businesses span one or more of the following verticals: Explore &amp; Discover, Develop, Extract &amp; Transport, Market &amp; Trade. Natural Gas (NG) is a key component of the Natural Resources industry, which contributes both directly and indirectly to sustain and support the day to day energy needs of humans. Various forums drive key(More)
Surgically created arteriovenous fistulae (AVF) for hemodialysis can contribute to hemodynamic changes. We describe the cases of 2 male patients in whom new right ventricular enlargement developed after an AVF was created for hemodialysis. Patient 1 sustained high-output heart failure solely attributable to the AVF. After AVF banding and subsequent(More)
