The basic aim of this study was to determine the effect of different conditioning agents on the properties of the sands and the effect of shear rate on the shear strength.
[8], at temperatures between 4[degrees]C and 20[degrees]C, the viscosity of GOS syrup with 75% of dry matter extract was correlated to a Newtonian behavior, that is, independent of the shear rate applied, whereas, at 50[degrees]C, a shear thinning effect was observed.
In the rheometer setup, rheological parameters were tested through controlling shear rate (CSR).
Flow profile showed that shear stress was increased with increase of shear rate but it decreased at higher shear rate (100 s-1) in heated emulsion.
When coated, the plastisol formulation is subjected to a wide shear rates range (up to [10.sup.5] [s.sup.-1]) and a too high viscosity at low shear rate makes its introduction between the knife and the rotating cylinder difficult.
This is called shear thinning, and the rate of deformation of the paint as it is sheared is called the shear rate (units are reciprocal seconds, [s.sup.-1]).
Another aspect concerns the yield point, which is the pair (shear rate, shear stress) where the flow is initiated.
However, BFR significantly impairs the increase in blood flow velocity and shear rate observed during exercise (18).
The unique features of the m-VROCi efficiently meet an established need in many industries for high shear rate viscometry.
It has long been established that blood is "shear thining": viscosity decreases as shear rate increases.
Research indicates that mixing equipment, water temperature and shear rate affect particle size.
