Electron diffraction analysis of charge redistribution model and structure of SeF6
(Elsevier, 1984-08)
The bond length of the octahedral molecule SeF6 was found to be rg(3[sigma]) = 1.685(2) A. Mean amplitudes of vibration, measured by diffraction, were within the experimental error of those calculated from spectral data ...
Murine glucocorticoid receptors and the H-2 locus--A reappraisal
(Elsevier, 1984-12)
It has been demonstrated that susceptibility to glucocorticoid-induced formation of cleft palate is regulated by the mouse histocompatibility complex (H-2). This has encouraged us to examine H-2 effects on glucocorticoid ...
On Green's functions, propagators, and sturmians for the nonrelativistic coulomb problem
(John Wiley & Sons, Inc., 1984-03-01)
Recent progress in the mathematical physics and quantum chemistry of Coulomb Green's functions is summarized. Analogy with the defining relation for the Green's function has led to a finite model for the Fermi contact ...
Cholesterol monohydrate dissolution rate studies in aqueous micellar solutions of polyoxyethylene nonylphenol ether and ionic surfactants
(Elsevier, 1984-10)
The influences of electrical and other factors on the dissolution kinetics of cholesterol monohydrate in micellar solutions were quantified in terms of mass transfer resistances due to interfacial processes and ...
Fractal to classical crossover of chemical reactions
(Elsevier, 1984-05-18)
Computer simulations on binary reactions of random walkers (A + A --> A) on two- and three-dimensional percolation clusters bear out the recent superuniversality conjecture (integrated reaction rate [alpha] t213). ...
Gravity-induced flocculation
(Elsevier, 1984-09)
In polydisperse colloidal systems, flocculation can occur as a result of the differential creaming rates between small and large particles. As an improvement on earlier work, we have rigorously modelled this process of ...
Preparation of 1-deuterioaldehydes via tub use of diisobutylaluminum deuteride (DIBAL-D)
(Elsevier, 1984)
Deuterioaldehydes, essential precursors In the preparation of chiral primary deuterioalcohols, have been prepared in yields ranging from 55-75% via reduction of methyl and ethyl esters at -78[deg]C with diisobutylaluminun ...
Hydroformylation as a simple and efficient one carbon homologation of homoallylic alcohols. Synthesis of prelog-djerassi lactone.
(Elsevier, 1984)
A hydroformylation oxidation sequence is described for the efficient conversion of homoallylic alcohols to [delta]-lactones. The methodology is applied to the synthesis of Prelog-Djerassi lactone.
Changes occur in central adrenoreceptor function following long-term morphine treatment and during morphine withdrawal
(Elsevier, 1984-12)
Radioloigand binding techniques were used in combination with electrophysiological recording to characterize changes in beta adrenoreceptor activity in various brain areas in rats treated chronically with morphine. Following ...
Comparison of "selective" opiate receptor antagonists on the isolated mouse vas deferens
(Elsevier, 1984-12)
The selectivity and relative potencics of opiate receptor antagonists were compared on the mouse vas deferens preparation. ICI-174864 was found to be a highly selective antagonist at delta opiate receptors equal in potency ...
