The scotopic visibility curves of two observers have been measured by determining their absolute thresholds for monochromatic lights and by direct comparison matching just above the threshold, in a 10 degree field with its centre 15 degrees above the fixation point. The results were all similar to the CIE scotopic curve. However, the threshold results in… (More)
A comprehensive picture of the interface between aqueous solutions and the (110) surface of rutile (alpha-TiO2) is being developed by combining molecular-scale and macroscopic approaches, including experimental measurements, quantum calculations, molecular simulations, and Gouy-Chapman-Stern models. In situ X-ray reflectivity and X-ray standing-wave… (More)
When medical care is initiated at a mass casualty event, the first activity is the triage of victims, which is the grouping by victims severity of injury. Paper triage tags are often used to mark victims' triage status and to record information on injuries and treatments administered in the field. In this paper we describe the design and development of… (More)
In a mass casualty situation, medical personnel at the disaster site and other field treatment settings may need to monitor the vital signs of hundreds of seriously injured patients with minimal staffing. The conditions may be primitive and personnel may have to improvise infrastructure. As part of our research to enhance medical response to disasters with… (More)
Coronafacic acid (CFA), the polyketide component of the phytotoxin coronatine (COR), is activated and coupled to coronamic acid via amide bond formation, a biosynthetic step presumably catalyzed by the CFA ligase (cfl) gene product. The COR biosynthetic gene cluster in Pseudomonas syringae pv. glycinea PG4180 is located within a 32-kb region of a 90-kb… (More)
We report new measurements of the asymmetry in the deep inelastic scattering of longitudinally polarized electrons by longitudinally polarized protons in the kinematic range 2<w<lO, 1<Q2<4 (GeV/c)2, and-2<W<4 GeV.-We compare our results with the Bjorken sum rule and with several theoretical models of the internal spin structure of the proton.
Twenty-four observers matched monochromatic lights to a white reference light in a 10 degree field. The retinal illuminance was 1000 Td over most of the spectrum. Twelve persons' visibility curves were more or less additive and resembled the y10 color-matching function of the CIE. Eight others had a double-peaked function, which failed badly to obey Abney's… (More)
Nonadditivities in 10 degrees color matches have been studied with regard to a hypothesis about the effect of the Maxwell spot. Rod intrusion was eliminated by adding a fourth instrumental stimulus to the usual three stimuli of colorimetry and then determining the matches that were unaffected by attenuation with a rotating-sector disk. To avoid other… (More)
