Identifying the underlying mechanisms of energy dissipation during post-yield deformation of bone is critical in understanding bone fragility fractures. However, the orientation-dependence of post-yield properties of bone is still poorly understood. Thus, the objective of this study was to determine the effect of loading direction on the evolution of post-yield behavior of bone using a progress...

The electron beam which IS accelerated in the SLAC two-mile accelerator exhibits both transverse and longitudinal interactions with the disk-loaded waveguide, The transverse interactions include such effects as rf steering caused by field asymmetries which exist in the couplers, and beam breakup, The latter is a growing instability which occurs above a given current threshold and deflects the b...

I c-. The acceleration and transport of beams with high currents and low emittances are very carefully controlled for the SLC Linacl. Both longitudinal and transverse wakefields affect strongly the trajectory and emittance corrections used for operations during collisions. Longitudinal beam loading introduces an internal energy spread. This loading produces the expected doubled peaked energy sp...

OBJECTIVE Diabetic neuropathic patients show a peculiar loading pattern of the foot, which led us to hypothesize that a substantial modification exists in their deambulatory strategy. The aim of the present study was to support this hypothesis by quantifying the changes of the loading patterns and by monitoring the excursion of center of pressure (COP) during gait. RESEARCH DESIGN AND METHODS...

The effect of upper airway loading on longitudinal bone growth and various components of the growth hormone (GH)/insulin-like growth factor I (IGF-I) axis has not been fully elucidated. In the present study, the effect of chronic resistive airway loading (CAL) in a prepubescent rat model on linear bone growth and weight gain was investigated. We hypothesize that CAL induced in prepubescent rats...
