Ultrasonication offers great potential in the processing of liquids and slurries, by improving the mixing and chemical reactions in various applications and industries. Ultrasonication generates alternating low-pressure and high-pressure waves in liquids, leading to the formation and violent collapse of small vacuum bubbles. This phenomenon is termed cavitation and causes high speed impinging liquid jets and strong hydrodynamic shear-forces. These effects are used for the deagglomeration and milling of micrometre and nanometre-size materials as well as for the disintegration of cells or the mixing of reactants. In this aspect, ultrasonication is an alternative to high-speed mixers and agitator bead mills. Ultrasonic foils under the moving wire in a paper machine will use the shock waves from the imploding bubbles to distribute the cellulose fibres more uniformly in the produced paper web, which will make a stronger paper with more even surfaces. Furthermore, chemical reactions benefit from the free radicals created by the cavitation as well as from the energy input and the material transfer through boundary layers. For many processes, this sonochemical (see sonochemistry ) effect leads to a substantial reduction in the reaction time, like in the transesterification of oil into biodiesel .
CT Fletcher’s need to remain atop the world of powerlifting led him to consume lots calories from unhealthy processed foods like burgers. At first, the unhealthy habit did not affect his body; he only grew bigger and stronger. After some time, he developed hypertension, which advanced to heart problems. In 2005 he went through a life-saving open heart surgery to save his life. CT Fletcher heart attack was so severe that he flat-lined three times during the operation. He spent the next couple of months recovering in an intensive care unit.
