Abstract:
:We compare diverging evolution of a two-component (gas+stars) galactic disk embedded in a "live" halo with that of an identical pure stellar disk. Our modeling supports the conjecture that the growth of central concentration in galaxies dissolves the main family of regular orbits in the stellar bar and assists in the formation of a galactic bulge.

杂志文章abstract::Huperzine A has been shown to be useful in the treatment of symptoms of dementia of the Alzheimer type. Our initial attempts to synthesize (-)Huperzine A resulted in the racemic mixture of (+/-)Huperzine A. We have therefore compared the in vitro and in vivo effects of (+/-)Huperzine A with those of (-)Huperzine A in ...
