Vibration discomfort of supine human body exposed to whole-body vibration: effect of vibration direction and magnitude.

Supine postures are increasingly adopted in medical transport, long-duration flights, and other healthcare environments. This study is aimed to identify the effect of vibration direction and magnitude on the objective and subjective responses of the human body in a supine posture. The transmissibilities to the head, chest, abdomen, and thighs of 12 male subjects were measured with single-axis random vibrations in longitudinal ( axis), lateral ( axis), and vertical ( axis) direction at 0.

Dislocation Strengthening without Ductility Trade-off in Metastable Austenitic Steels.

Strength and ductility are mutually exclusive if they are manifested as consequence of the coupling between strengthening and toughening mechanisms. One notable example is dislocation strengthening in metals, which invariably leads to reduced ductility. However, this trend is averted in metastable austenitic steels.
