As excess water is discharged from a high dam, low frequency noise (air pulsation lower than 10 Hz, LFN) is generated and propagated in the surrounding areas, causing environmental hazards such as the vibration of windows and doors and the discomfort of local residents. To study the generation mechanisms and key influencing factors of LFN induced by flood discharge and energy dissipation from a...

BACKGROUND Substrate-based ablation is useful for nonhemodynamically tolerated postinfarct ventricular tachycardia. We assessed the accuracy of the CARTO contact and EnSite noncontact systems at identifying scar in a chronic ovine model with intramural plunge needle electrode recording and histological validation. METHODS AND RESULTS Scar mapping was performed on 8 male sheep with previous pe...

Splashing is the main atomization source for a jet impinging on liquid layer. Increased understanding of splashing rainfall characteristics can help to reduce hazard flood discharge in hydraulic engineering. In this study, spatial distribution caused by nappe flow downstream water cushion was experimentally investigated. Effects factors impingement velocity, unit discharge, and water-cushion de...
