Nonprofits in the United States must comply with various state and federal regulations to maintain their tax-exempt status. Despite persistent calls to increase accountability in the nonprofit sector, there is little research examining the burden imposed by existing regulatory requirements, especially at the state level. This paper uses a bunching design to estimate the avoidance behavior exhib...

Escherichia coli (E.coli) O157 that do not produce Shiga toxin and do not possess flagellar antigen H7 are of diverse H serotypes. In this study, the antibiotic resistance properties, genotype of a set of virulence associated genes and the phylogenetic background of E. coli O157:non-H7 groups were compared. Whole genome sequencing was performed on fourteen O157:non-H7 isolates collected in the ...

Mutational studies directed at evaluating the effect of the axial ligand plane orientation on electrochemical properties of cytochrome b5 have been performed. As described in the previous paper, structural consequences of one of these mutations, the A67V mutation, have been evaluated using NMR solution methods. The lack of large shifts relative to the wild-type protein in both the imidazole Nde...

Brookes, Paul S., and Victor M. Darley-Usmar. Role of calcium and superoxide dismutase in sensitizing mitochondria to peroxynitrite-induced permeability transition. Am J Physiol Heart Circ Physiol 286: H39–H46, 2004. First published August 28, 2003; 10.1152/ ajpheart.00742.2003.—The mitochondrial permeability transition pore (PTP) is a membrane protein complex assembled and opened in response t...

Accurate measurement of pulsar distances via astrometry using very long baseline interferometry enables the improvement of Galactic electron density distribution models, improving distance estimates for the vast majority of pulsars for which parallax measurements are unavailable. However, pulsars at southern declinations have been under–represented in previous interferometric astrometry campaig...

Buckwalter, John B., and Philip S. Clifford. a-Adrenergic vasoconstriction in active skeletal muscles during dynamic exercise. Am. J. Physiol. 277 (Heart Circ. Physiol. 46): H33–H39, 1999.—Sympathetic vasoconstriction in working muscles during dynamic exercise has been demonstrated by intra-arterial administration of a1-adrenergic antagonists. The purpose of this study was to examine the existe...
