The development of collateral circulation has been indirectly monitored by determining peripheral coronary pressure and Xe clearance. In the present experiments, the development of collateral blood flow following gradual (three dogs) and rapid (three dogs) complete occlusion of the central circumflex branch, during partial central occlusion, and in parallel with a rise in peripheral coronary pr...
Probabilistic Neural Network prediction of liquid- liquid two phase flows in a circular microchannel
The present work proposes towards flow pattern prediction in a liquidliquid microchannel flow through a circular channel. Mass transfer in a microchannel mainly depends on the flow regime inside the channel. The liquid-liquid two phase flow regime in a microchannel depends on the flow velocity and the junction characteristics. Hence, the prediction of patterns has a superior role for the charac...
Two-phase vertical downward flow in plate heat exchangers: Flow patterns and condensation mechanisms
SUMMARY We evaluated electrocardiogram-synchronized flow-sensitized 4-dimensional MR imaging at 3T in combination with advanced 3D visualization strategies to ascertain its feasibility for the assessment of local intracranial blood-flow patterns in vivo. In large arteries of healthy volunteers, the temporal and spatial evolution of blood flow was successfully visualized and revealed--for exampl...
