Approximate solution for the flow past an impulsively started infinite porous plane wall in an elastico-viscous fluid is obtained for the velocity and shearing stress. The roles of elasticity of the liquid and the suction on the velocity and the shearing stress have been studied. 相似文献

Corrections to results of electric field gradient (EFG) already published [Pramana — J. Phys.41, 443 (1993)] are reported. The corrected net EFG is:q=−8.01×1013 esu/cm3 against the published valueq=16.06×1013 esu/cm3. The present result agrees reasonably well with the experimental result, |q
expt|=13×1013 esu/cm3.
Recently, a computational error is detected, which modifies the results of EFG, we have already published [1]. The error was
committed mainly in the part that evaluated thep-p contribution [1] to EFG by the conduction electrons. The corrected results are summarized in table 1 which must replace the
table 1 of the published work [1].
In addition, the lattice parameters as well as the temperature were also misquoted in the previous work [1]. The right parameters
are:a=6.25311 au andc=9.96509 au. The temperature at which EFG’s are calculated is 293 K instead of 11 K as reported before [1].
The discussions and conclusions made in the published work [1] remain almost unchanged except that they now refer to the corrected
numbers. Although the corrected net EFG suffers a sign reversal from the one already published [1], the agreement with experiment
is still considered reasonably good because the sign of experimental EFG is not determined. The computational error however
does not affect the introduction and theory section of the published work [1]. 相似文献

This is the report of neutrino and astroparticle physics working group at WHEPP-8. We present the discussions carried out
during the workshop on selected topics in the above fields and also indicate progress made subsequently. The neutrino physics
subgroup studied the possibilities of constraining neutrino masses, mixing and CPT violation in lepton sector from future
experiments. Neutrino mass models in the context of Abelian horizontal symmetries, warped extra dimensions and in the presence
of triplet Higgs were studied. Effect of threshold corrections on radiative magnification of mixing angles was investigated.
The astroparticle physics subgroup focused on how various particle physics inputs affect the CMBR fluctuation spectrum, and
on brane cosmology. This report also contains an introduction on how to use the publicly available code CMBFAST to calculate
the CMBR fluctuations. 相似文献

As part of a program for studying hyperfine interactions at surfaces of condensed matter systems, we have studied the nuclear quadrupole interactions associated with group VI and VII atoms adsorbed on silicon surface. The electronic structures used for these investigations were determined through the self-consistent Hartree-Fock cluster procedure using sizeable clusters of atoms to simulate the infinite systems. Results will be presented for the nuclei of halogen atoms adsorbed on the silicon (111) surface and for sulfur and selenium atoms on the (110) surface. 相似文献
