A new methodology for implementing radioactive particle tracking (RPT) in bubble columns with intense vertical rod internals was developed and implemented to investigate the effect of dense on hydrodynamics. The utilizes a hybrid Monte Carlo N-Particle (MCNP) simulation an automated RPT calibration device generate large number points accurate reconstruction instantaneous positions particles usi...

Porous Ta and Al layers that exhibit 280-nm-wide micropores, which are interconnected by 5–50-nm-wide nanopores, were grown by glancing angle deposition GLAD . The micropore nucleation is facilitated by patterning Si 001 substrates with inverted-pyramidal pit arrays using anisotropic etching through lithographic masks obtained by colloidal self-assembly. The microstructure consists of vertical ...

The initial goal of this study was to establish an accounting of the major classes of cells present in the inner nuclear layer (INL) of the rabbit's retina. Series of 80-100 radial sections 1 micron thick were cut from retinal blocks dissected at intervals along the vertical meridian. They were photographed at high magnification in the light microscope. By visualizing the initial segments of pr...

This study tested the effects of perceived t ime pressure on subjective visual vertical (SVV) perception in co llege healthy male students. Delayed down-weighting of inaccurate visual cues has been implicated in age-induced overreliance on visual informat ion, which may be disruptive for postural control. Accordingly, I hypothesized that under time pressure, participants may not have enough tim...
