EVOLUTION OF GALACTIC DISCS: TWO MODES OF STAR FORMATION ABSTRACT We develop the model of the evolution of surface gas density, stellar density, star formation rates and chemical composition of galactic disc taking into account the gravitational instability of rotating gaseous layer in the scales of several kpc. ... In the model we took into account the gas return from evolved stars, a radial movement of the gas in a spiral arms and accretion of the gas into the galactic disc. ...

... Abstract: We present a search for a low-mass Standard Model Higgs boson produced in association with a z boson decaying to charged leptons at a center-of-mass energy of s\sqrt{s}=1.96~TeV with the D0 detector at the Fermilab Tevatron collider. The search is performed in a large data set of events containing two opposite-sign leptons (electron, muon) and one or two b-tagged jets. 4:00pm, 472 Willamette Hall . ...

It was concluded also from these investigations that it is problematic to produce emitting electrons from a background plasma by stochastic (Fermi) acceleration because the energy supplied by external sources in the form of Fermi acceleration is quickly absorbed by background plasma. ...
