This thesis investigates the reliability of printed conductors on flexible substrates under cyclic bending. The topic is approached by studying the effects of several key design parameters on the bending lifetime of printed conductors under dynamic loading. In this thesis, the test specimens with various cross-sectional geometries were printed on different plastic and paper substrates. The test...

The purpose of this work is to use 3D finite element analyses to compute bending of a hard disk suspension using a laser. The pitch and roll of the suspension can be precisely adjusted by producing a controlled amount of residual strain using the laser as a heat source. In the computational model, an uncoupled thermo-mechanical analysis is applied to calculate the laser induced thermal loading ...

Chemically synthesized duplex oligodeoxynucleotides having different average numbers of adenine tracts (A6) per helix turn were ligated into multimers and analyzed by electrophoresis on polyacrylamide gels. The magnitude of the anomaly in gel mobility is found to be a quadratic function of the curvature of the DNA molecule. Parameters that describe intrinsic DNA bending, expressed as the tilt a...

OBJECTIVES/HYPOTHESIS Persistent direction-changing positional nystagmus (DCPN) during the supine head-roll test is a typical finding of cupulopathy. The aim of this study was to introduce a simple method of evaluating patients with cupulopathy (light cupula and heavy cupula), which is performed in a seated position, and investigate its diagnostic utility and use for lateralization. STUDY DES...

BACKGROUND Numerous studies have shown that there are better alternatives to log rolling patients with unstable spinal injuries, although this method is still commonly used for placing patients onto a spine board. No previous studies have examined transfer maneuvers involving an injured football player with equipment in place onto a spine board. PURPOSE To test 3 different transfer maneuvers ...
