An Arcminute-Resolution Imaging Study of the H-alpha & [S II] Emission of the ISM from the Local Perseus Arm Using the Virginia Tech Spectral-Line Survey
… see similar structures, and notice the same [S II]/H-alpha trend between those structures at both degree and arcminute scales. VTSS fields show three basic types of structures --- compact clouds with diameters greater than several degrees, those that are 1-degree or less in diameter, and …

Narrowing the Margin: The Role of the Black Superhero
<p>Comic books can be understood as a visualization of popular culture in the U.S. For a long time these tales were formed by a white power fantasy, circulating in mainstream culture as over-exaggerated narrations. To give an example of white power fantasy, Dwayne McDuffie, a prolific writer in …

The P Cluster of the Azotobacter vinelandii Nitrogenase Complex: Effects of Substitution at the Cluster-bridging Residue, a-Cys88
… crystal structure of the Azotobacter vinelandii MoFe protein, it was had been determined which of the highly conserved cysteinyl residues of this protein were likely P cluster ligands. After elucidation of the crystal structure, it became evident that cysteine-88 of the a-subunit (a-Cys88) and …

Proactive strategies in personal dose monitoring, prevention and mitigation
… and characterize radioactive source(s), (ii) determine the impact of localized source(s), and (iii) estimate the integrated doses in traversing/evacuating the facility. The scope of this work does not extend to the development of "proactive" dosimeter. However, the approaches developed in …

Interaction between ferric hydroxides and dissolved sulfide in anoxic aquifers: Pathway and kinetics of iron and sulfur products formation
The interaction between ferric iron (Fe(III)) and sulfide (S(-II)) is of great importance in permanent or temporary anoxic environments. It is a major component of the biogeochemical cycling of both iron and sulfur and eventually of carbon. Electron transfer between ferric iron and sulfide leads to …

Studies of TeV Gamma-Ray Sources in the Hydrogen-Alpha Optical Line
… intensity ratio of ionised sulphur to H𝛼 [S II] / H𝛼 indicating that it is a SNR. There is a need to look for similar counterparts in H𝛼 towards TeV gamma-ray surveys that have some interesting features. We use the archival data from optical H𝛼 survey, as well as the HESS galactic plane …

The biogeochemistry of 210Pb and 210Po in fresh waters and sediments
… support substantial diffusive fluxes. Fe, Mn, S(II), and alkalinity did not have similar gradients. 210Pb partition coefficients ranged from 1500 to 15000, decreasing with depth, and seemed to be controlled by sorption on iron oxides. Remobilization to the water column apparently comes from a …
