Radiating spherical collapse with heat flow

We present here a simple model of radiative gravitational collapse with radial heat flux which describes qualitatively the stages close to the formation of a superdense cold star. Starting with a static general solution for a cold star, the model can generate solutions for the earlier evolutionary stages. The temporal evolution of the model is specified by solving the junction conditions appropriate for radiating gravitational collapse.Comment: 13 pages, including 3 figures, submitted to IJMP-

The Crystallography of Strange Quark Matter

Cold three-flavor quark matter at large (but not asymptotically large) densities may exist as a crystalline color superconductor. We explore this possibility by calculating the gap parameter Delta and free energy Omega(Delta) for possible crystal structures within a Ginzburg-Landau approximation, evaluating Omega(Delta) to order Delta^6. We develop a qualitative understanding of what makes a crystal structure stable, and find two structures with particularly large values of Delta and the condensation energy, within a factor of two of those for the CFL phase known to characterize QCD at asymptotically large densities. The robustness of these phases results in their being favored over wide ranges of density and though it also implies that the Ginzburg-Landau approximation is not quantitatively reliable, previous work suggests that it can be trusted for qualitative comparisons between crystal structures. We close with a look ahead at the calculations that remain to be done in order to make contact with observed pulsar glitches and neutron star cooling.Comment: 6 pages, 3 figures.

Bacteriological Status Of Meat During Various Stages Of Processing In AFD Packing Plant

Studies on eight carcasses(sheep/goat) for microbial status of meat at different stages of processing viz dressed carcass before after chilling, after boning, cocking, cooking, cooling, slicing, deep freezing, freeze drying, and packing have been carried out. No difference in microbial status has been observed in sheep and goat carcass. The lower (front body) portion of carcass has higher microbial load than the upper portion (hind body). No significant increase in total colony counts was observed on keeping the carcass for 24 hours at 5 degree centigrade. The highest microbial load has been observed on boned meat. The total colony counts (TCC) gets reduced during the process of deep freezing and freeze drying. The precooked, freeze dried meat has TCC up to 266
