Relations between the membrane potential and the tension associated with changes in membrane potential were analyzed in barnacle giant muscle fibers by using voltage clamp techniques. With a step change in membrane potential the tension reaches its final level with a time course which is expressed by the difference of two exponential functions. The time constants tau(1) (0.2-0.4 sec at 23 degre...

suspension polymerization processes are significantly important in polymer bead formation. one of the important factors for bead size control in these processes is variation in surface tension. in this research, the prediction of optimum concentration of a surface active agent was investigated on the basis of the experimental surface tension diagrams. the experimental data show that the desired...

1. The migrations of the chromatophores of the yolk sac of Fundulus heteroclitus seem to be chemotropic in character. 2. The determining factor seems to be either a high tension of oxygen or a comparatively low concentration of hydrogen ions.

Experiments were designed to assess the intrinsic changes in myocardial function with age and to determine the role of increasing left ventricular mass in this process. Isometric ventricular pressure-volume curves and length-tension curves were measured in isolated perfused rat hearts of different ages and masses. Incremental tension, peak active tension, and peak passive tension were less for ...

Current patches made from macromolecular compounds or composix for tension-free herniorrhaphy are still unsatisfactory in biocompatibility. The ideal patch should be a biological patch with good biocompatibility. Herein allograft patches modified by tissue engineering were used in tension-free herniorrhaphy of swines. Tough membrane tissues from swine were modified with patented tissue engineer...

he main objective of the advertising discourse is to encourage its viewer or reader to buy goods. this dialogue contains several inductive functions, including inductive functions of action and tension. the function of the induced action is an action-induced origin, whereas the function of the inductive tension is induced by the action originated. thus, tension-induced functions can be claimed ...

Abstract: In this study an algorithm for mold-filling simulation with consideration of surface tension has been developed based on a SOLA VOF scheme. As the governing equations, the Navier-Stokes equations for incompressible and laminar flows were used. We proposed a way of considering surface tension in mold-filling simulation. The proposed scheme for surface tension was based on the conti...

BACKGROUND Limited intrinsic healing potential of the meniscus and a strong correlation between meniscal injury and osteoarthritis have prompted investigation of surgical repair options, including the implantation of functional bioengineered constructs. Cell-based constructs appear promising, however the generation of meniscal constructs is complicated by the presence of diverse cell population...
