Predictability of Optic Foramen Location From a Ray Through the Ethmoidal Foramina.

Purpose: To determine how accurately a ray through the anterior and posterior ethmoidal foramina predicts the location of the optic foramen.

Methods: Dried, well-preserved, complete human skulls without bony defects belonging to the Hamann-Todd osteological collection of the Cleveland Museum of Natural History were examined. Photography was performed and a ray was drawn on orbit photographs extending through the center of the anterior and posterior ethmoidal foramina toward the optic canal.

Finite-element analysis of magnetic field driven transport at inlaid platinum microdisk electrodes.

We describe a computer-assisted analysis of three-dimensional magnetohydrodynamic (MHD) fluid flow resulting from the passage of electrochemically generated charge through a uniform magnetic field. Magnetic field driven molecular transport in electrochemical systems offers a number of emerging opportunities in research and technology. For instance, electrochemical microfluidic transport and molecule trapping using magnetic fields and field gradients have been demonstrated in recent reports from this laboratory.
