Low-temperature heat capacities, thermophysical properties, optical spectra, and analysis of Schottky contributions to Pr(OH)3
(Elsevier, 1979-09)
From values of the heat capacity of microcrystalline Pr(OH)3 determined by precise adiabatic calorimetry from 15 to 350 K, the Schottky contribution associated with all but the lowest Stark level was resolved with the aid ...
Gas chromatographic determination of gallopamil and norgallopamil in human plasma
(Elsevier, 1989)
A highly sensitive gas chromatographic assay is described for the simultaneous determination of gallopamil, a calcium channel blocking agent, and its major metabolite, norgallopamil. A multi-step extraction procedure is ...
The effect of daily ingestion of caffeine on the microsomal enzymes of rat liver
(Elsevier, 1973-02)
The effect of repeated ingestion of caffeine on rat-liver microsoma enzymes was studied. In the rat, ingestion of 20-24 mg caffeine/kg/day in the drinking water for more than 2 wk inhibited aminopyrine N-demethylase activity. ...
Iodine analysis of biological samples by neutron activation of 127I, with scintillation counting of cerenkov radiation
(Elsevier, 1971-03)
The naturally occurring isotope, 127I, has been measured by neutron activation, postirradiation extraction of 128I plus 127I (added carrier), and timed scintillation counting of aqueous solution utilizing Cerenkov radiation. ...
Measures of viability in isolated cells
(Elsevier, 1975-06)
Various methods were compared for estimation of cell viability. Cell count, uptake of trypan blue, release of cellular LDH, as well as cell contents of K+ and Na+ were determined in leukocytes, spleen cells, and Ehrlich ...
Thermodynamics of copper sulfides I. Heat capacity and thermodynamic properties of copper(I) sulfide, Cu2S, from 5 to 950 K
(Elsevier, 1987-11)
The heat capacity of Cu2S from 5 to 950 K was determined by adiabatic-shield calorimetry and the thermodynamic properties were evaluated. Transitions occur at 376 and about 710 K with [Delta]trsSm = (1.240+/-0.006)R and ...
