Sloshing interaction in ship collisions is studied both experimentally and numerically. The rapid change in ship motions resulting from contact loading in collisions initiates violent sloshing inside partially filled liquid tanks on board. Sloshing affects the collision dynamics and reduces the amount of energy available for structural deformations. An understanding of this interaction phenomen...

Early telemetry from the spin-stabilized IMAGE spacecraft indicated that the vehicle’s initial nutation was not decaying. This behavior was especially puzzling because the spacecraft’s passive nutation damper behaved as expected while IMAGE was attached to the spinning upper stage. The lack of damping was also puzzling because the damper was a tubular ring partially filled with liquid mercury; ...

Empty sel la refers to the radiological appearance of an enlarged or deformed sella turcica that is partially or completely filled with cerebrospinal fluid. In the earlier days, the radiographic appearance of an enlarged sella turcica was frequently equated with the presence of an intra or perisellar neoplasm. It was found, however, in some of these patients on pneumoencephalography, that the e...
