The need to destabilize foams and control their formation arises in many industrial applications. Vibrations are known to affect the structure and rheology of various soft solids but have not been exploited in destroying persistent foams. Being noninvasive, they offer elegant potential alternatives

## Abstract An ultrasonic generator was tested at 3 frequencies for its effects on __Serratia marcescens__ during fermentation. The generator controlled foam adequately at 26, 29, and 34 kc/sec at medium aeration rates up to 0ยท6 ft^3^/min. Final viable counts were in the same range as those for cul
Experiments were conducted to study the effect of ultrasonic vibrations on heat transfer during the rapid quenching of thin horizontal platinum wires in subcooled water and ethanol. The frequency of ultrasonic vibration was 24 and 44 kHz. The power input to the transducer P ranged from 0 to 280 W. T
## Abstract The shape and size of voids, and the grown region surrounding a large void were investigated in In~__x__~Ga~1โ__x__~Sb crystals, which were pulled under the introduction of ultrasonic vibrations into the source melt by using a modified Czochralski apparatus. The presence of voids in cry
