The nonlinear propagation through porous media is investigated in the framework of Biot theory. For illustration, and considering the current interest for the determination of the elastic properties of granular media, the case of nonlinear propagation in "model" granular media (disordered packings of noncohesive elastic beads of the same size embedded in a visco-thermal fluid) is considered. Th...

In three previous papers5,6,7),functional properties of spindle,leaf-like and tendon receptors in the frog sartorius muscle have been compared with each other during contractions or passive stretch of the muscle.It has been demonstrated that those properties were not only dependent upon the excitability of their sensory nerve endings,but also largely upon the visco-elastic properties of the und...

Commonly used polymer-based scaffolds often lack visco-elastic properties to serve as a replacement for cartilage tissue. This study explores the effect of reinforcement of silk matrix with chitosan microparticles to create a visco-elastic matrix that could support the redifferentiation of expanded chondrocytes. Goat chondrocytes produced collagen type II and glycosaminoglycan (GAG)-enriched ma...
