Commercial synthesis of monoalkyl phosphates
Autor: David J. Tracy, Robert Lee Reierson
Publikováno v: Journal of Surfactants and Detergents. 5:169-172
Historically, phosphate esters have been prepared by the reaction of alcohols with phosphoric anhydride or polyphosphoric acid. Recently, hybrid reagents have been developed. A review of the commercial production of long-chain monoalkyl phosphate est

Effects of Permeation of Helium through the Walls of Fused Silica Capillary GC Columns
Autor: David H. Tracy, Jerry E. Cahill
Publikováno v: Journal of High Resolution Chromatography. 21:531-539
Hold-up times and peak widths have been measured in long fused silica GC capillary columns at high temperature with helium as the carrier gas. The results lead to the conclusion that the helium permeates through the column walls. The conventional Poi

Multivariate methods for interpretation of emission spectra from the inductively coupled plasma
Autor: Juan C. Ivaldi, Walter Slavin, David H. Tracy, Thomas W. Barnard
Publikováno v: Spectrochimica Acta Part B: Atomic Spectroscopy. 47:1361-1371
Multivariate methods are described which improve the quality of the information which is extracted from inductively coupled plasma (ICP) atomic emission spectra. The enhancements provided by these methods result from using more of the spectral inform

Publikováno v: Current Surgery. 56:410-412
Introduction: High-resolution computed tomography (CT) scans now detect smaller pulmonary nodules than were ever detected before, which has created new clinical challenges regarding the timing and method of obtaining a tissue diagnosis. Video-assiste

Localization of pulmonary nodules using suture-ligated microcoils
Autor: Lawrence M. Casha, Sean P Murray, John P. Reinschmidt, George J. Collins, David A. Tracy, Ronald A. Gagliano
Publikováno v: Journal of computer assisted tomography. 25(2)
Percutaneous localization of pulmonary nodules in five patients was performed utilizing suture-ligated embolization microcoils and CT guidance. Each localization was performed prior to video-assisted thoracoscopic wedge resection of the targeted nodu

Absolute spectral radiance of 27 MHz inductively coupled argon plasma background emission
Autor: S.A. Myers, David H. Tracy
Publikováno v: Spectrochimica Acta Part B: Atomic Spectroscopy. 37:1055-1068
The spectral radiance of the plasma continuum of a 27 MHz argon ICP has been measured for two sets of operating conditions in the wavelength range from 192 to 600 nm. At an rf forward power of 1250 W and a viewing height of 15 mm above the load coil,
