Abstract: Oxygen is essential to maintaining normal brain function. A large body of evidence suggests that the partial pressure of oxygen (pO2) in brain tissue is physiologically maintained within a ...

Abstract: Axial gas transport due to the interaction between radial mixing and radially nonuniform axial velocities is responsible for gas transport in thick airways during High-frequency oscillatory ...

Abstract: A microscopic velocimetry technique for evaluating the flow field over cultured endothelial cells was developed. Flow around a cell model scaled up by a factor of 100 was visualized by using ...

Abstract: The possible mechanism of wheeze generation in tracheostenosis was identified by measuring inspiratory and expiratory flow in a “morphological and distensible” realistic tracheostenosis model. The ...

Abstract: A serpentine gas exchange unit was built with cylindrical tubular microporous membranes featuring periodic arcs with a fixed curvature ratio (ratio of tube radius to radius of curvature) of ...

Abstract: We report on flow phenomena such as wall shear stress and periodic oscillations that occur in the right-angle branch during laminar steady flow in the upstream trunk. The side-branch bifurcates ...
