We present a first physical application of Tsallis’ generalized entropy to the thermodynamics of self-gravitating systems. The stellar system confined in a spherical cavity of radius re exhibits an instability, so-called gravothermal catastrophe, which has been originally investigated by Antonov (Vest.Leningrad Gros.Univ. 7 (1962) 135) and Lynden-Bell & Wood (Mon.Not.R.Astron.Soc. 138 (1968) 49...

12 rearranged human VH6 immunoglobulin heavy chain genes arising from the same rearrangement were isolated without preselection from the RNA of a fragment of human spleen. The 12 clones were isolated from a pool of 31 unique VH6 clones arising from 18 unique rearrangements. 2 of the 12 related clones were expressed with IgM, 2 with IgG, and 8 with IgA1. All the clones, including those expressin...

While the oxidation of ammonia is an integral component of advanced aerobic livestock wastewater treatment, the rate of nitrification by ammonia-oxidizing bacteria is drastically reduced at colder temperatures. In this study we report an acclimated lagoon nitrifying sludge that is capable of high rates of nitrification at temperatures from 5 degrees C (11.2mg N/g MLVSS/h) to 20 degrees C (40.4 ...

Abstract The aims of this study were to estimate genetic parameters, predict genotypic values, and analyze the divergence in S0 S1 peach trees evaluated a subtropical environment by mixed model methodology. For this, twenty-two clones for plant fruit traits. Genotypic variance among was significant. individual broad-sense heritabilities ranged from 0.11 0.84, repeatability coefficients 0.15 0.8...
