Steady-shear rheology of concentrated chitosan solutions
(2004)
The rheological properties of 0.5 - 2.0% (wt/wt) chitosan solutions in steady-shear were investigated as a function of temperature (25C - 45C), acid type (acetic, lactic, and hydrochloric), and ionic strength (0 and 0.2 M ...
Thixotropic Behavior of Oil-in-Water Emulsions Stabilized with Ethoxylated Amines at Low Shear Rates
(2019)
© 2019 WILEY-VCH Verlag GmbH & Co. KGaA, WeinheimOil-in-water (O/W) emulsification is a lubricating pipeline method based on the reduction of the energy frictional loss produced during viscous flow. The flow behavior of ...
Direct Shear Test of Unsaturated Soil
(Universidad Nacional de Colombia - Sede Bogotá - Facultad de Ciencias - Departamento de Geociencia, 2017-10-01)
The present study focuses on some tentative laboratory tests using a newly-constructed modified direct shear test apparatus. The single-stage and multistage direct shear tests were performed to determine the shear rate and ...

Irreversible thermodynamics approach and modeling of shear-banding flow of wormlike micelles
(2002)
The flow in a pipe of wormlike micellar solutions is examined using a simple model that consists of the codeformational Maxwell constitutive equation and a kinetic equation that accounts for the breaking and reformation ...

Deformation and geochronology of syntectonic granitoids emplaced in the Major Gercino Shear Zone, southeastern South America
(ELSEVIER SCIENCE BV, 2010)
The Major Gercino Shear Zone is one of the NE-SW lineaments that separate the Neoproterozoic Dom Feliciano Belt, of Brazil and Uruguay, into two different domains: a northwestern supracrustal domain from a southeastern ...
INFLUENCIA DEL GAS METANO EN LAS PROPIEDADES MECÁNICAS DE LA ARCILLA MARINA
(2012-07-03)
To understand the behavior of clay soil containing gas, it is necessary to know the
compressibility and strength parameters derived from field and laboratory tests, as done for clay sediments without gas. For that, ...
Procedure to Evaluate the Shear Rate Profile and the Apparent Viscosity of Non-Newtonian Fluids in the Falling Cylinder Viscometer
(Planta Piloto de Ingeniería Química, 2007-12)
The falling cylinder viscometer (FCV) is a reliable instrument to quantify the viscosity of Newtonian fluids. Nevertheless, when non-Newtonian fluids are tested in this device, difficulties appear to determine the apparent ...
