Total radiances and equivalent widths of Doppler lines for nonisothermal paths
(Elsevier, 1967)
An analytical method similar to that used by (1) on Lorentz lines was applied to the problem of the growth of an isolated Doppler line for the case of nonisothermal paths. The results, given in terms of the total radiance ...
Selective resonance enhanced multiphoton ionization of aromatic polymers in supersonic beam mass spectrometry
(Elsevier, 1991-07-15)
Various polymers have been studied using a pulsed laser evaporation method for volatilizing these species and entraining them into a supersonic jet expansion followed by resonance enhanced multiphoton ionization (REMPI) ...
Chemiluminescence of nitric oxide: The NO (C2[Pi]-A2[Sigma]+) rate constant
(Elsevier, 1981-05)
A rocket borne scanning 1/4-m spectrometer was used to observe the night airglow between 1900 and 2300 A at a resolution of 15 A. An attitude control system oriented the payload horizontally near apogee (150 km) and pointed ...
A Novel Application of the MIRC Repository in Medical Education
(Springer-Verlag; SCAR (Society for Computer Applications in Radiology), 2005-06)
Medical students on the radiology elective in our institution create electronic presentations to present to each other as part of the requirements for the rotation. Access was given to previous students’ presentations via ...
The “water-ida”: A simple means to separate duodenal from gallbladder activity on cholescintigraphic studies
(Springer-Verlag, 1984-07)
In some 99m Tc-iminodiacetic acid studies, separation of the gallbladder from the duodenum can be difficult, despite multiple views. When faced with this problem, we have had the patient ingest 250 cc of tap water. This ...
Successful and unsuccessful approaches to imaging carcinoids: Comparison of a radiolabelled tryptophan hydroxylase inhibitor with a tracer of biogenic amine uptake and storage, and a somatostatin analogue
(Springer-Verlag, 1996-02)
A mouse mastocytoma model was used to determine the biodistribution and tumour uptake of four radiopharmaceuticals developed to target the serotonin synthetic pathway in carcinoid tumours. Three of the compounds were ...
Resonance enhanced multiphoton ionization of nucleosides by using pulsed-laser desorption in supersonic beam mass spectrometry
(Elsevier, 1989-04-01)
Pulsed-laser desorption is used as a means of volatilizing nucleosides into the gas phase for entrainment into a supersonic jet expansion. These species are then studied in a time-of-flight mass spectrometer by resonance ...
The electronic absorption spectrum of crystallinechromyl chloride at 1.7[deg]K
(Elsevier, 1968-01)
The spectrum of chromyl chloride, CrO2Cl2 , in the region 6000 A-3800 A hasbeen obtained for the crystalline substance at temperatures down to 1.7[deg]K. Three absorption systems have been observed, together with the start ...
Interpretation of the vibrational behavior of methyl and substituted methyl radicals perturbed by alkali halide molecules
(Elsevier, 1970-12)
The observed vibrational behavior of free and alkali halide-perturbed methyl radicals in low temperature inert matrices is rationalized on the basis of the relaxation of the molecular charge distribution of the methyl ...
The emission and absorption spectra of chromyl chloride in an argon matrix at 4 K
(Elsevier, 1974-07)
The emission and absorption spectra of chromyl chloride (and the pure 35Cl isotopic species) have been obtained in an argon matrix at 4 K. In emission, two systems are obtained and these correlate with the two systems ...
