Instability resulting from a missed Chance fracture.

D improvements in seat and seat-belt designs, lap-belt injuries continue to occur in children. The diagnosis of abdominal and spinal injuries is often delayed or missed completely. Heightened awareness, a good history and physical examination, as well as the appropriate investigations are required for the prompt diagnosis of such injuries. We present the case of a young boy with a lap-belt inju...

Stratification instability in granular flows

When a mixture of two kinds of grains differing in size and shape is poured in a vertical two-dimensional cell, the mixture spontaneously stratifies in alternating layers of small and large grains, whenever the large grains are more faceted than the small grains. Otherwise, the mixture spontaneously segregates in different regions of the cell when the large grains are more rounded than the smal...

Conductivity-limiting bipolar thermal conductivity in semiconductors

Intriguing experimental results raised the question about the fundamental mechanisms governing the electron-hole coupling induced bipolar thermal conduction in semiconductors. Our combined theoretical analysis and experimental measurements show that in semiconductors bipolar thermal transport is in general a "conductivity-limiting" phenomenon, and it is thus controlled by the carrier mobility r...
