Many are calling for changes for internal medicine training, arguing that changes in the practice environment mandate changes in how the internal medicine residency is structured. Residency could be shorter, more conducive to role differentiation among general internists, and more supportive of subspecialization. Training could provide more experience in ambulatory care, multidisciplinary team-...

In the dynamic diffusion limit of radiation hydrodynamics, advection dominates diffusion; the latter primarily affects small scales and has negligible impact on the large scale flow. The radiation can thus be accurately regarded as an ideal fluid, i.e., radiative diffusion can be neglected along with other forms of dissipation. This viewpoint is applied here to an analysis of simple waves in an...

geophysical fluids such as atmosphere and ocean often have stable density stratification; hence internal gravity waves are generated and propagated through them which are important in momentum and energy transfer in these media. these waves are also believed to generate layered structures in such media. recently there have been numerous theoretical, experimental and numerical studies on the way...
