Electro-osmosis (EO) is a non-traditional pumping and transduction mechanism with the ability to project acoustic energy in fluids. This investigation experimentally validates the influence of zeta potential, a well-studied physical characteristic used for quantifying the efficacy of an EO pump, on generation of sound pressure level. Acoustic signals of discrete frequencies were observed from 130 Hz to over 150 kHz.

As yearly civil commitments rates have decreased in Oregon, competency to stand trial commitments to Oregon State Hospital have increased, suggesting an inverse relationship between these two important statutes.
