Abstract:
Most of safety control standard studies for existing tunnels under blasting vibrations are based on the premise that the existing tunnels are intact, and the effects of existing defects under the dynamic response are not considered. Therefore, based ...

Abstract:
The “pump theory” and “wave theory” of cardiac function are analyzed. It is shown that the heart plays a role actually not as a pump but as a pulse generator, producing a series of pulse waves that carry energy. Each pulse wave consists of an ascendi...

Abstract:
The loading of bubble jet is an important part of the whole loading induced by the middle-field and near-field underwater explosion. Due to the fact that the period of the bubble jet is extremely short and the jet occurs inside the complicated underw...
