Stellar density and bar strength should affect the temperatures of the cool (T ~ 20-30 K) dust component in the inner regions of galaxies, which implies that the ratio of temperatures in the circumnuclear regions to the disk should depend on Hubble type. ... The strong radiation field in the high stellar density of a galactic bulge tends to heat the cool dust component to higher temperatures, at least in early-type spirals with relatively large bulges, especially when paired with a strong bar. ...

INFLUENCE OF STRONG DISORDER ON SUPERCONDUCTIVITY OF MgB2 THIN FILMS Th. ... D-91058, Erlangen, Germany (Received 12 May 2008) Abstract We investigated the influence of disorder on superconductivity of MgB2 films, prepared in a single deposition run onto two different substrates: (100)-MgO and on (128° rot)-LiNbO3 with trigonal crystal structure which does not match to the MgB2 structure. ...
