Heat capacity and thermodynamic properties of synthetic heazlewoodite, Ni3S2, and of the high-temperature phase Ni3±xS2
(Elsevier, 1991-01)
The heat capacity of synthetic heazlewoodite (Ni3S2) was measured over the temperature range 5 K to 350 K by equilibrium adiabatic calorimetry and compared with earlier results. High-temperature results on this phase and ...
Stereoselective high-performance liquid chromatographic assay for pirmenol enantiomers in dog plasma
(Elsevier, 1991-12-15)
Pirmenol enantiomers in dog plasma were quantified using a stereospecific high-performance liquid chromatographic method with ultraviolet detection at 262 nm. Racemic pirmenol and internal standard, (+)-propranolol, were ...
Continuous monitoring of gas-phase species at trace levels with electrochemical detectors : Part 1. Direct amperometric measurement of hydrogen peroxide and enzyme-based detection of alcohols and sulfur dioxide
(Elsevier, 1991-08-01)
A simple detection system suitable for the continuous measurement of atmospheric hydrogen peroxide in the parts per trillion (1012) volume (pptv) range is described. The proposed method involves the use of a flowing recipient ...
Ultrafiltrate of saliva collected in situ for the measurement of testosterone
(Elsevier, 1991-08-01)
A device for the in situ collection of an ultrafiltrate of saliva was investigated. The collector consists of an osmotic pump that, when placed in the mouth, accumulates a prepurified salivary filtrate within a few minutes. ...
Thermodynamic properties of ammonium haloplatinates: II. Heat capacity and thermodynamic functions of deuterated ammonium hexachloroplatinate (ND4)2PtCl6 at temperatures from 5 K to 350 K
(Elsevier, 1991-07)
The heat capacity of deuterated ammonium hexachloroplatinate (ND4)2PtCl6 was measured at temperatures from 5 K to 350 K by adiabatic calorimetry. One λ-shaped anomaly, absent in the undeuterated salt, was found in ...
A quantitative dot-blot immunoassay for integral membrane proteins: Preparation of pancreatic plasma membranes containing apical and basolateral domains
(Elsevier, 1991-01)
Modifications of standard dot-blot immunoassay techniques have been made for the quantitation of integral membrane protein antigens. The modification involves the signal development step, which is performed by using ...
A synthesis of (+)-7-Epiaustraline and (-)-7-Epialexine
(Elsevier, 1991-09-30)
Reductive cyclization of the azido epoxides 19[alpha] and 19[beta] followed by deprotection afforded the HIV inhibitor (+)-7-epiaustraline 7 and (-)-7-epialexine 9. The formation of 7 proceeded with an unusual inversion ...
Priming effect of glucagon-like peptide-1 (7-36) amide, glucose-dependent insulinotropic polypeptide and cholecystokinin-8 at the isolated perfused rat pancreas
(Elsevier, 1991-02-19)
The priming effect of glucagon-like peptide-1 (7-36) amide (GLP-1 (7-36) amide), glucose-dependent insulin-releasing polypeptide (GIP) and cholecystokinin-8 (CCK-8) on glucose-induced insulin secretion from rat pancreas ...
Hydrodesulfurization over model sulfide cluster-derived catalysts
(Elsevier, 1991)
There is growing interest in the use of organometallic clusters as precursors to model heterogeneous catalysts. This interest is partially derived from the expectation that "solid-state metal complex catalysts" will be ...
Stochastic aspects of turbulent combustion processes
(Elsevier, 1991-02)
Methods of using stochastic simulations to treat nonlinear interactions in turbulent combustion processes are described -- emphasizing the use of statistical time-series techniques to analyze the turbulence--radiation ...
