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 ...
متن کاملThixotropy 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...
متن کاملThixotropy 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...
متن کاملThixotropy of rib cage respiratory muscles in normal subjects.
In this study, we searched for signs of thixotropic behavior in human rib cage respiratory muscles. If rib cage respiratory muscles possess thixotropic properties similar to those seen in other skeletal muscles in animals and humans, we expect resting rib cage circumference would be temporarily changed after deep rib cage inflations or deflations and that these aftereffects would be particularl...
متن کاملThixotropy of nasal medications—its role in clinical practice.
Optimal medication should be characterized by good bioavailability, rapid onset of action, a long period of therapeutic activity, with preserved high safety profile and the lowest possible risk of side effects. Therefore, in addition to traditional drug administration routes, such as oral or injection, novel methods for drug applications, for example in the form of a nasal application have been...
