South Africa adopted the GATS Basic Agreement on Telecommunications and the regulatory principles in 1998. Obligations undertaken by South Africa
This paper is a sequel to the series of papers [gr-qc/9409010, gr-qc/9505034, gr-qc/9603022, gr-qc/9609035, gr-qc/9609046, gr-qc/9704033, gr-qc/9704038, gr-qc/9708014], being an
We describe the localization transition of superfluids on two-dimensional lattices into commensurate Mott insulators with average particle density p/q (p,
In order that current and future renormalon results in QCD can be used to their full advantage it is important
We model magnetization processes that take place through tunneling in crystals of single-molecule magnets, such as Mn_12 and Fe_8. These
We review the characteristics of nucleosynthesis in 'Hypernovae', i.e., supernovae with very large explosion energies ($ \gsim 10^{52} $ ergs).
Symmetrization of bosonic wave functions produces bunching and low temperature phenomena like Bose-Einstein condensation, superfludity, superconductivity, as well as laser.
We show that the quasiparticle effective mass $M^*$ diverges as a function of the system's density $x$, $M^*\propto 1/(x-x_{FC})$, when
We derive the spin-dependent Bethe-Salpeter equation for $q\bar{q}$ bound state at finite temperature in the ladder and cross box diagram
The Cosmic Microwave Background (CMB) consists of photons that were last created about 2 months after the Big Bang, and
Here we present a pilot study into whether elliptical galaxy counts alone, can place a useful constraint on the Omega_M
We describe a research program to improve the understanding of Type Ia Supernovae (SNe Ia) by modeling and observing near
The edge-on Sc galaxy NGC 5907 has been observed in the 12CO(1-0)-line emission using the Nobeyama 45-m telescope. The radial
Cosmological limits on Lorentz invariance breaking in Chern-Simons $(3+1)-dimensional$ electrodynamics are used to place limits on torsion. Birefrigence phenomena is
We identify 998 closed hyperbolic 3-manifolds whose volumes are rationally related to Dedekind zeta values, with coprime integers $a$ and
Photoinduced dynamics of charge density and lattice displacements is calculated by solving the time-dependent Schrödinger equation for a one-dimensional extended
Quantum gravity may lead to an energy dependence in the speed of light. The high energy radiation from gamma-ray pulsars
We place limits on the linear power spectrum on small scales (k > 50 h/Mpc) using measurements of substructure in
Computational Grids are emerging as a platform for next-generation parallel and distributed computing. Large-scale parametric studies and parameter sweep applications
With approximately 6000 QSO redshifts,the 2dF QSO redshift survey is already the biggest complete QSO survey. The aim for the
In a previous publication we have shown that the gauge theory of relativistic 3-Branes can be formulated in a conformally
We present preliminary results from a 900 ks exposure of NGC 3783 with the Chandra/HETGS. This is the best combination
Accurate relative abundances have been obtained for a sample of 21 mildly metal-poor stars from the analysis of high resolution
We present a comprehensive study of the evolution of the abundances of intermediate mass elements, from C to Zn, in
