In this work, a 3-D simulation is performed to study for the solid-fluid coupling effect driven by piezoelectric materials and utilizes asymmetric obstacles to control the flow direction. The result of simulation is also verified. For a micropump, it is crucial to find the optimal working frequency which produce maximum net flow rate. The PZT plate vibrates(More)
The National Environmental Education Foundation (NEEF) launched an initiative in 2005 to integrate environmental management of asthma into pediatric health care. This study, a follow-up to a 2013 study, evaluated the program's impact and assessed training results by 5 new faculty champions. We surveyed attendees at training sessions to measure knowledge and(More)
