Hydrodynamic Detonation Instability in Electroweak and QCD Phase Transitions

The hydrodynamic stability of deflagration and detonation bubbles for a first order electroweak and QCD phase transition has been discussed recently with the suggestion that detonations are stable. We examine here the case of a detonation more carefully. We find that in front of the bubble wall perturbations do not grow with time, but behind the wall modes exist which grow exponentially. We briefly discuss the possible meaning of this instability.Comment: 12 pages, 3 figures available on request, Latex, FERMILAB--PUB--93/098--

Spatial structure of 2,2-dimethyl-5-alkyl-1,3,2,5-dioxasilaphosphorinanes

A study was made of the IR spectra and dipole moments of some heterocycles that simultaneously contain phosphorus and silicon atoms. The preferential conformation of the dioxasilaphosphorinanes is discussed. © 1979 Plenum Publishing Corporation

Rotational isomerism of some 1-substituted silatranes

It was shown by the DM method that the γ′ conformation of the side chain is realized in the 1-γ-halo-propylsilatranes, the gauche form is realized predominantly in the 1-thioethoxymethylsilatranes, while a trans orientation of the C-S bond with respect to the silatrane fragment is realized in the 1-β-thioethoxye-thylsilatranes. © 1978 Plenum Publishing CorporationPlenum Publishing Corporation

Anisotropy of polarizability of the silatranes

1. Polarizability parameters have been determined for the Si-C and Si-O bonds. The Si-O bond of the siloxanes does not show axial symmetry. 2. The axes of the molecular polarizability ellipsoid for 1-methylsilatrane have been determined. 3. The transannular N → Si bond shows a pronounced anisotropy of polarizability in the silatranes. © 1977 Plenum Publishing Corporation
