Satellite Laser Ranging (SLR) data have been analyzed by ourselves and other groups to provide e~imstes of the secular variations in the zonal harmonics of the geopotential field. While the SLR data available frum late-1992 onward me superior in satellite and temporal coverage (two station shifts in operation by the NASA Network), SLR alma extending back to the mid-1970s have been utilized by s...

The President's Council on Bioethics has addressed the moral status of human preembryos in its reports on stem cell research and human therapeutic cloning. Although the Council has been criticized for being hand-picked to favor the right-to-life viewpoint concerning human preembryos, it has embraced the idea that the right-to-life position should be defended in secular terms. This is an importa...

religion, as a social phenomenon, affects society and is affected by it interactively. in iran, basically with religious norms and laws, many scholars and researchers concern with religion and level of religiosity. the paper is a comparative analysis of level of religiosity based on glynn and stark’s dimensions of religiosity, in three different generations in sari city: first generation (pre-r...

For singular perturbation problems in dynamical systems, various appropriate singular perturbation methods have been proposed to eliminate secular terms appearing in the naive expansion. For example, the method of multiple time scales, the normal form method, center manifold theory, and the renormalization group method are well known. It is shown that all of the solutions of the reduced equatio...

The present investigation deals with the propagation of waves in a micropolar transversely isotropic layer. Secular equations for symmetric and skew-symmetric modes of wave propagation in completely separate terms are derived. The amplitudes of displacements and microrotation were also obtained. Finally, the numerical solution was carried out for aluminium epoxy material and the dispersion curv...

The present investigation deals with the propagation of waves in the layer of an anisotropic fibre reinforced thermoelastic solid. Secular equations for symmetric and skew-symmetric modes of wave propagation in completely separate terms are derived. The amplitude of displacements and temperature distribution were also obtained. Finally, the numerical solution was carried out for Cobalt material...
