Study Design Case report and review of the literature. Objective To present a unique case of L5 radiculopathy caused by a sacral stress fracture without neurologic compression. Methods We present our case and its clinical evolution and review the available literature on similar pathologies. Results Relief of the unusual mechanical loading causing sacral stress fracture led to rapid resolution o...

The electrical conductance and principal structural and mechanical properties of gold nanowires, exhibiting reversibility in elongation-compression cycles at ambient conditions, were investigated using pin-plate experiments and molecular dynamics simulations. Underlying the reversible nature of the nanowires are their crystalline ordered structure and their atomistic structural transformation m...

Detached broad bean (Vicia faba L.) leaflets were water stressed; within 15 minutes, guard-cell abscisic acid (ABA) concentration increased ninefold. This result eliminates the apparent discrepancy raised by reports of no correlation between initial water-stress effects on stomata and leaf ABA concentration. Six hours after stress relief, guard-cell ABA concentration was near the prestress valu...

Current studies have not conclusively demonstrated an objective and consistent marker of an aberrant stress response; an effect of such a stress response on reproductive outcome; or a benefit of counseling on reproductive outcome in such patients.

Stress-relieving heat treatment is reported to accelerate the elastic memory process in order that the configuration of cold-worked orthodontic wires becomes more stable. In this experiment, 3 methods of stress-relieving O.036-inch cobaltchromium orthodontic wires used in the fabrication of spacemaintaining appliances were evaluated. The results showed that stress relief in a dental oven, by th...

Based on first principles calculations, we studied the structural properties of group V elements P, As, Sb and Bi on the Si(001) surface. For one monolayer of the group V atoms on the Si(001) substrate, stress and stress anisotropy scaled almost linearly with atomic size, implying that the obvious source of surface stress was atomic size effect. We found that stress relief was responsible for t...
