[1] In a recent paper by Polyakov and Nearing (2003) it was shown experimentally that the sediment transport capacity in a rill is not unique for a given soil type, slope, and flow rate. Indeed, they found that the transport capacity was dependent on whether sediment transport in the rill was occurring under net erosion or net deposition conditions. They concluded that this nonuniqueness in tra...

This paper summarizes our theoretical understanding of supernova events in a “back of the envelope” way. It is intended to aid in the recognition and understanding of those events which are not “standard”, and which may provide the most insight.

Radiography is the most widely utilized imaging modality for measuring joint damage in early rheumatoid arthritis.

The recognition of these limitations has led to intense interest in ultrasonography and magnetic resonance imaging for assessing synovitis and ...
