Design and Development of a Novel Expanding Pedicle Screw for Use in the Osteoporotic Lumbar Spine
… A materials testing machine performed axial load to failure tests in both Sawbones and cadaveric specimens comparing the new design to traditional screws (rate = 10mm/min to 20 mm). Output parameters included yield load, ultimate load, stiffness, energy to failure and total energy. The …

Mechanical Control of Sensory Hair-Bundle Function
… range in height from 1 μm to 100 μm and in stiffness from 100 μN/m to 10,000 μN/m. They are composed of actin-filled, hypertrophic microvilli—stereocilia—that number from fewer than 20 through more than 300 per bundle. In addition, bundles may or may not possess one true cilium, the …

Development of high-response piezo servovalves for improved performance of electrohydraulic cylinder drives
This book deals with the development and testing of high-response piezo-servovalves for improved performance of electrohydraulic cylinder drives. Performance improvement means in the context of this work an enhancement of reference and disturbance response of the drive in a closed-loop pressure and …
