Oroville Dam Spillway Failure Page 15 Metabunk

Feb 8, 2017 Not sure if engineers take the venturi effect lifting the concrete into account – rather than the more 'logical' weight pressing downwards. Saw this same thing happening at an airport. The apron was cracking so they laid enormous 2.5 cm thick sheets of steel on them as a temporary measure. A B757 opened 

Venturi Easy Ambient SonicSpray Ionization Analytical Chemistry

Jan 14, 2011 The sonic gas stream causes two beneficial and integrated effects: (a) the selfpumping of solutions via the Venturi effect and (b) sonicspray ionization (SSI) of analytes either in solution or resting on solid surfaces. In its liquid mode, VLEASI is applicable to analytes in solution, forming negatively and/or
