Abstract Through the study of diameter control horizontal swirling efficiency shaft and tunnel cross-section aeration sill, a flood discharge with scale about 100 meters volume more than thousand is obtained. The energy dissipation type combined diversion tunnel. At time, can be controlled determined according to average velocity 15-20m/s; hole calculated empirical formula D=(Q 2 /g) 0.2 . In o...

Herein, we report the recent proliferation of non-native serpulid worm Ficopomatus enigmaticus in parts Galveston Bay, Texas. Reef-like aggregations were first recovered from a settlement plate and submerged brick at Kemah Boardwalk Marina on 4 May 2023. By 20 May, similar growths reported to us by floating docks, boat hulls, propellers, rudders. On June 8, nearby marinas remained unaffected. W...

Near-death experience (NDE) is a complex subjective experience, which may include affective elements such as a sense of peacefulness, paranormal components such as a sensation of floating out of the body, and a perception of being in a dark tunnel and seeing a brilliant light. It is usually reported to occur in association with a wide range of life-threatening situations, as for instance, cardi...

This letter describes the fabrication and structural and electrical characterization of an aerosol-nanocrystal-based floating-gate field-effect-transistor nonvolatile memory. Aerosol nanocrystal nonvolatile memory devices demonstrate program/erase characteristics comparable to conventional stacked-gate nonvolatile memory devices. Aerosol nanocrystal devices with 0.2 mm channel lengths exhibit l...
