Focused ultrasound (FUS) in combination with microbubbles (MBs) has been successfully used in the delivery of various-size therapeutic agents across the blood-brain barrier (BBB). This study revealed that FUS-induced BBB opening size, defined by the size of the largest molecule that can permeate through the BBB, can be controlled by the acoustic pressure as dictated by cavitational mechanisms. ...

Hydrodynamic cavitation, created by the intensive movement of secondary discrete part in an electromechanical device, is most important energy effect processing petroleum products. The presented work contains and summarizes results study main parameters cavitation processing, including geometric elements part, speed trajectory as well processed raw materials. It established that to achieve inte...

This paper numerically discusses how the performance of a NACA marine propeller is affected by the number of blades, which is one of the most crucial geometrical parameters determining the performance of a propeller. Results are presented in terms of the hydrodynamic and structural parameters. The results show that changing the number of blades changes the hydrodynamic efficiency, torque, thrus...
