Abstract: There is a potential problem that hazardous and flammable materials are accidentally or intentionally released into the atmosphere, either within or close to populated urban areas. For the assessment of human health hazard from toxic substances, the existence of high concentration peaks in a plume should be considered.  »»»

When a disk rotates at constant angular velocity in otherwise still fluid a boundary layer flow is established close to the disk. Obviously the local velocity of the disk increases with radius, but to a first approximation, this radial variation of the basic flow can be neglected to produce a "local" parallel-flow linear stability theory.  »»» 

The highly accurate simulation of turbulent rotating flows within cavity is of interest for both engineering applications, such as designing rotational machinery, and fundamental research, as one of the simplest cases where the turbulent boundary layers are three-dimensional. Attempting to compute these flows using statistical approaches has had only partial success.  »»» 

Resume: The objective of ERASMUS project was further development and testing the new noninvasive diagnostics method of human skin under variable mechanical loading in-vivo. The method is based on monitoring instantaneous changes of ultrasound propagation along the skin.  »»»
