We investigate the global evolution of the viscous stage of a turbulent protoplanetary disk. The time-dependent radial development of the nebula is calculated with the help of analytical onezone models of the vertical structure that relate optical properties of grains to turbulent viscosity.

## Abstract We present projected rotational velocity measurements of the red giant in the symbiotic star MWC 560, using the highβresolution spectroscopic observations with the FEROS spectrograph. We find that the projected rotational velocity of the red giant is __v__ sin __i__ = 8.2 Β± 1.5 km s^β1^
