Towed-body observations of mixing over the continental slope reveal the great lateral extent (several km) of continuously turbulent fluid within a few hundred meters of the boundary at 1600 m depth. The largest turbulent dissipation rates were observed over a 5 km horizontal region near a slope critical to the M 2 internal tide. Averaged over a submarine(More)
PURPOSE Extracellular matrices were tested for their ability to support the adhesion and proliferation of human corneal endothelial cells. METHODS Human corneal endothelial cells were plated onto tissue culture dishes coated with purified fibronectin or a matrix elaborated by cultured bovine corneal endothelial cells. The presence of human cells in the(More)
A 12-day series of 1749 profiles of turbulent kinetic energy dissipation above the equatorial undercurrent at 140 degrees west showed that, in the upper 110 meters of the ocean, the dissipation radically decreased during the solar heating period each day. Daily averages were linearly related to the local wind power. When integrated over the depth range of(More)
Visibility analysis has traditionally been restricted to point-to-point line-of-sight profiling or point-to-area viewshed analysis. This constrained view of visibility necessarily limits our ability to understand the visibility surface characteristics of the terrain. Recent research by the University of Edinburgh has resulted in the development of a(More)
