According to the new preheating mechanism of galaxy formation suggested by Mo et al., we construct a simple model of formation of disk galaxies within the curre
The brightness temperature distribution of microwave emission in a solar active region generally shows a ring structure, with a dip at the centre. However, no d
Based on a dynamic model for turbulent convection, we investigate the effects of dissipation and anisotropy of the turbulence on the convective energy transport
