let a be a banach algebra. a is called ideally amenable if for every closed ideal i of a, the first cohomology group of a with coefficients in i* is trivial. we investigate the closed ideals i for which h1 (a,i* )={0}, whenever a is weakly amenable or a biflat banach algebra. also we give some hereditary properties of ideal amenability.
we show that every semi-artinian module which is contained in a direct sum of finitely presented modules in $si[m]$, is weakly co-semisimple if and only if it is regular in $si[m]$. as a consequence, we observe that every semi-artinian ring is regular in the sense of von neumann if and only if its simple modules are $fp$-injective.
Background: Members of the eukaryotic Hsp90 family function as important molecular chaperones in the assembly, folding and activation of cellular signaling in development. Two hsp90 genes, hsp90 alpha and hsp90 beta, have been identified in fish and homeothermic vertebrates but not in poikilothermic vertebrates. In the present study, the expression of hsp90 alpha and hsp90 beta genes in Xenopus...
استهسال انرژی ایجاد شده بر اثر ارتعاش ناشی از گردابه ها (vortex induced vibrations for aquatic clean energy) یا بطور مختصر vivace روشی نوین برای تولید انرژی پاک از جریان سیالات است.در این روش عبور جریان از اطراف یک استوانه باعث ایجاد ارتعاش شده و نیروی مورد نیاز برای حرکت دادن یک مولد الکتریکی را فراهم می آورد.
