In this work we consider the global existence of volume-preserving crystalline curvature flow in a non-convex setting. We show that natural geometric property, associated with reflection symmetries Wulff shape, is preserved flow. Using address and regularity for smooth anisotropies. For non-smooth case establish results types anisotropies known to be globally well-posed.

The influence of pulsatile diameter changes on calculation of volume flow has been studied. In vitro studies and an animal study were carried out with a real-time imaging and pulsed Doppler velocity measurement system. For precise pulsatile diameter information a wall motion tracking device was incorporated. Whereas in vitro a high degree of accuracy was found for the measurements of volume flo...

• The Ralculation of central (thoracic, pulmonary) blood volume from indicator-dilution data was introduced by Stewart' and developed and applied mainly by Hamilton and his group.The so-called classical Stewart-Hamilton method was based on the premise that the product of flow rate and mean transit time defined the volume of the flow channels. Originally intuitive, this premise has recently been...

Interfaces, across which fluid and flow properties change significantly, are a ubiquitous feature of most turbulent flows and are present within jets, plumes, homogeneous turbulence, oceans and planetary atmospheres. Even when the interfaces occupy a small volume fraction of the entire flow, they largely control processes such as entrainment and dissipation and can act as barriers to transport....

Data on pulmonary function, with particular reference to flow-volumes, were obtained in 760 normal healthy Indians in Bombay, who had never smoked and who had no symptom or history of cardiorespiratory disease. Prediction equations were derived for spirometric parameters and for maximal expiratory flows. The maximal expiratory flow-volume curves showed considerable intersubject variability. Bot...
