instabilities of a thin viscous film flowing down a uniformly heated plane are investigated in this study. the heating generates a surface tension gradient that induces thermocapillary stresses on the free surface. thus, the film is not only influenced by gravity and mean surface tension but also the thermocapillary force is acting on the free surface. moreover, the heat transfer at the free su...

We experimentally revisit the flow down an inclined plane of dense granular suspensions, with particles sizes in micron range, for which thermal fluctuations cannot be ignored. In contrast standard rheology, strongly depends on size. A phenomenological model based sum a contribution describing glass transition and athermal capturing jamming is developed, reproduces well experimental observations.

Studies of insect flight have focused on aerodynamic lift, both in quasi-steady and unsteady regimes. This is partly influenced by the choice of hovering motions along a horizontal stroke plane, where aerodynamic drag makes no contribution to the vertical force. In contrast, some of the best hoverers--dragonflies and hoverflies--employ inclined stroke planes, where the drag in the down- and ups...

prior animal models have shown that rats sustaining 3-second immediate spinal cord compression had significantly better functional recovery and smaller lesion volumes than rats subjected to compression times of 1 hour, 6 hours, 3 weeks, and 10 weeks after spinal cord injury. we compare locomotor rating scales and spinal cord histopathology after 3 seconds and 10 minute compression times. . ten ...
