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...

Thixotropy is the characteristic of a fluid to form a gelled structure over time when it is not subjected to shearing, and to liquefy when agitated. Thixotropic fluids are commonly used in the construction industry e.g., liquid concrete and drilling fluids , and related applications include some forms of mud flows and debris flows. This paper describes a basic study of dam break wave with thixo...

The viscous flow behavior of a 12.5 vol% hydrophobic fumed silica (Aerosil® R816) suspension in polypropylene glycol low molecular weight (PPG400) was studied stress-controlled rheometer. steady curve showed shear thickening between two thinning regions. Time-dependent viscosity response provoked by step changes stresses corresponding to the shear-thickening region apparently agrees with thixot...

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 ...

A composite gel composed of a water-soluble aromatic polyamide hydrogelator and the nanosheet Laponite®, a synthetic layered silicate, was produced and found to exhibit thixotropic behaviour. Whereas the composite gel contains the gelator at the same concentration as the molecular gel made by the gelator only, the composite gel becomes a softer thixotropic gel compared to the molecular gel made...

OBJECTIVES Increased resistance to stretch of muscles after stroke may be the result of centrally mediated neural factors such as spasticity or local, peripheral factors such as muscle contracture or thixotropy. The aim was to investigate evidence for an abnormal thixotropic response and compare this with two other factors-contracture and spasticity-which could potentially contribute to muscle ...
