Thixotropy: The Case of Mexico City Soils

Thixotropy implies non-equilibrium initial conditions after remolding. At the macroscale, thixotropy manifests as the regain in mechanical properties. At the microscale, thixotropy involves phenomena such as contact creep and interparticle force redistribution, homogenization of pore pressure (in saturated and partially saturated soils), altered ionic distribution and mobility, and the effects ...

Thixotropy of Blood and Proneness to Thrombus Formation

• "While the viscosity of blood lias been studied extensively (Copley, Stainsby, and Bayliss-), only a few studies have involved the use of a rotational viscometer. These included Brundage, Wells and Merril, and Wells et al.,-~ the latter applying a Brookfield cone plate viscometer. Neither study was carried out at rates of shear below 10 seer. The present author considered that the region belo...

Shear thinning and thixotropy of HMHEC and HEC water solutions

Steady state viscosity and thixotropy of hydrophobically modified hydroxyethyl cellulose ~HMHEC! and nonassociative cellulose water solutions are studied. Although all the samples are shear thinning, only the HMHEC is thixotropic, since the migration of hydrophobes to micelles is controlled by diffusion. The Cross model fits steady state curves. The Mewis model, a phenomenological model that pr...

Thixotropy and Rheopexy of Muscle Fibers Probed Using Sinusoidal Oscillations

Length changes of muscle fibers have previously been shown to result in a temporary reduction in fiber stiffness that is referred to as thixotropy. Understanding the mechanism of this thixotropy is important to our understanding of muscle function since there are many instances in which muscle is subjected to repeated patterns of lengthening and shortening. By applying sinusoidal length changes...
