Immunomodulatory Effects of Macrolide Antibiotics in Sulfur Mustard Exposed Airway Epithelial Cells: Quantum Dots-Mediated Immunocytochemical Analysis of iNOS and Diaminofluorescein-Mediated Flow Cytometric Analysis of Intracellular Nitric Oxide

October 12, 2021
Author(s)
X P. Gao, Radharaman Ray, Yan Xiao, Peter E. Barker, Prabhati Ray
Exposure of airway epithelial cells to 100 uM sulfur mustard significantly upregulated induced nitric oxide (iNOS) in cells. This response, quantitated by both flow cytometry and quantum dot-visualized antibodies, is returned to normal iNOS levels if cells

Imperfect Surface Order and Functionalization in Vertical Carbon Nanotube Arrays Probed by Near Edge X-ray Absorption Fine Structure Spectroscoy (NEXAFS)

October 12, 2021
Author(s)
T Hemraj-Benny, S Banerjee, S Sambasivan, Daniel A. Fischer, G Eres, Alexander Puretzky, David B. Geohegan, D H. Lowndes, J A. Misewich, S S. Wong
Probing surface order in nanotube systems is of fundamental importance for incorporation of these materials into practical electronic devices. The current study pertains to analysis of the surface orientation of vertically aligned single-walled and multi

Improved Facility for Optical Detector Characterization

October 12, 2021
Author(s)
T Flournoy, George P. Eppeldauer
The detector characterization and calibration facility of the Army Primary Standards Laboratory (APSL) has been extended. In addition to the traditional filter and monochromator based spectral measurements, laser-based sphere sources and high performance

Improved Theoretical X-Ray Resonant Scattering Amplitudes

October 12, 2021
Author(s)
J O. Cross, M I. Bell, M Newville, J J. Rehr, L B. Sorensen, Charles E. Bouldin, G Watson, T Gouder, G H. Lander
Resonant elastic scattering amplitudes [Δ]f = f[u'] + if[u''] in the vicinity of the absorption edges have been obtained by applying a differential Kramers-Kronig transform to theoretical absorption cross-sections calculated by the ab initio x-ray

Improved Transition Oscillator Probabilities for Laser Transitions in Xe I

October 12, 2021
Author(s)
Abhijit Dasgupta, J P. Apruzes, O Zatsarinny, K Bartschat, Charlotte F. Fischer
The atomic xenon laser is among the most efficient and powerful of thenear-infrared gas lasers, especially when pumped by molecular ions in an Ar-Xemixture. Accurate oscillator strengths for the laser transitions are criticaltodeveloping a fundamental

In-Situ Investigation of Water Transport in an Operating PEM Fuel Cell Using Neutron Radiography: Part 1 - Experimental Method and Serpentine Flow Field Results

October 12, 2021
Author(s)
T Trabold, Jon P. Owejan, David L. Jacobson, P R. Huffman
Effective management of liquid water produced in the cathodic reaction of a polymer electrolyte membrane (PEM) fuel cell is essential to achieve high cell efficiency. Few experimental methods are available for in-situ measurements of water transport within

Influence of Drawbeads in Deep Drawing of Plane-Strain Channel Sections

October 12, 2021
Author(s)
D E. Green, T B. Stoughton, Thomas H. Gnaupel-Herold, Mark Iadicola, Timothy J. Foecke
The Numisheet 2005 Benchmark 3 consisted of forming four different automotive sheet materials in a two-stage process. The first stage consisted of forming channel sections in an industrial-scale channel draw die in which material flow is controlled by
