The effect of collagen degradation on chondrocyte volume and morphology in bovine articular cartilage following a hypotonic challenge.

abstract：:In this paper we introduce a novel method for prescribing terminal boundary conditions in one-dimensional arterial flow networks. This is carried out by coupling the terminal arterial vessel with a poro-elastic tube, representing the flow resistance offered by microcirculation. The performance of the proposed porous m...
