چکیده
Gas bubbles of oxygen. carbon dioxide and nitrogen are injected into the degassed plasma and whole blood. The bubble size is measured at time intervals until the bubble is completely dissolved in the liquid. Physical quantities governing the dissolution of gas bubbles are identified and their effects are examined. The applications of the study include the dissolution of gas emboli in human body and the extracorporeal oxygenation of the blood during open heart surgery.

A two-dimensional numerical model was developed to determine the effect of the non-Newtonian behavior of blood on a pulsatile flow at the aortic bifurcation. The blood rheology was described by a weak-form Casson equation. The successive-over-relaxation (SOR) method was used to solve both the vorticity and Poisson equations numerically. It was disclosed that the non-Newtonian property of blood ...

A porous medium finite element model of the passive left ventricle is presented. The model is axisymmetric and allows for finite deformation, including torsion about the axis of symmetry. An anisotropic quasi-linear viscoelastic constitutive relation is implemented in the model. The model accounts for changing fibre orientation across the myocardial wall. During passive filling, the apex rotate...

We applied the pseudostrain energy function of Humphrey et al. [J. biomech. Engng 112, 333-346 (1990a, b)] to characterize the passive biaxial mechanical properties of the right ventricle free wall myocardium [Sacks and Chuong, J. biomech. Engng 115,202-205 (1993)]. The myocardium was assumed to be incompressible, pseudoelastic, and transversely isotropic, with transmural variations in fiber or...

The interaction between the semitendinosus muscle and both hip and knee joint angles was examined in the frog (Ranu pip&s) hindlimb. Sarcomere length was measured by laser diffraction in passive muscle during hip and knee rotation. A model was then developed to predict semitendinosus sarcomere length ;Ls a function of both hip and knee Rexion angle. Based on published frog muscle fiber length-t...
