Smear-layer debris was sonicated from dentine surfaces and trapped on microfilters for microscopy, which showed that the layers are composed, in part, of aggregates of globular subunits approx. 0.05-0.1 micron in diameter. Such globules were also seen in smear layers in situ and on fractured dentine surfaces. The composition of smear layers may reflect the(More)
We developed a 1/4-inch mild steel plate underbase with reinforced steel angles and three-inch diameter casters for our nonmotorized operating microscope floorstand. When fully weighted with an automatic focus zoom microscope head, a stereoscopic assistant scope, and a television camera, the unit proved stable and safe. It can be moved more easily than the(More)
Erosion influences the dynamical evolution of mountains. However, evidence for the impact of surface processes on tectonics mostly relies on the circumstantial coincidence of rugged topography, high stream power, erosion, and rock uplift. Using the optically stimulated luminescence (OSL) thermochronometry technique, we quantified the spatial and temporal(More)
