PURPOSE To investigate changes in dry eye symptoms and diagnostic test values after cataract surgery and to address factors that might influence those symptoms and test results. METHODS Twenty-eight eyes from 14 patients with preoperative dry eye (dry eye group) and 70 eyes from 35 patients without preoperative dry eye (non-dry eye group) were studied prospectively. In each group, we measured...

The perturbation to the momental figure of Ganymede by the impact basin Gilgamesh was modelled, and it was found that the format, ion of the basin could have significantly reoriented the satellite. Global trends of groove orientation suggest that groove sets formed in reactivated zones of weakness, which were created by tidal despinning and furrow formation. The paleo•ole n which despinning occ...

There continues to be a lot of interest in corn silage harvested with a self-propelled forage harvester (SPFH) equipped with an aftermarket processor with cross-grooved processing rolls set for 2to 3-mm roll gap and greater roll speed differential than has typically been used (32% versus 21%). Also, the developer of this processor recommends that the SPFH be set for a longer theoretical length ...

We demonstrate a multi-functional optical trap capable of trapping, motion control, position sensing and fluorescence detection of chemically treated polystyrene beads, using off-the-shelve optical components. It consists of two collinearly aligned single-mode fibers separated by a spacing of 130-170mum for trapping, another single-mode fiber for probing/pumping and a fourth multi-mode fiber fo...

We investigate the growth procedures for achieving taper-free and kinked germanium nanowires epitaxially grown on silicon substrates by chemical vapor deposition. Singly and multiply kinked germanium nanowires consisting of <111> segments were formed by employing a reactant gas purging process. Unlike non-epitaxial kinked nanowires, a two-temperature process is necessary to maintain the taper-f...

We present an experimental study of a low-Reynolds number shear flow between two surfaces, one of which has a regular grooved texture augmented with a superhydrophobic coating. The combination reduces the effective fluid-surface contact area, thereby appreciably decreasing the drag on the surface and effectively changing the macroscopic boundary condition on the surface from no slip to limited ...
