“…This behaviour was evident for all the sam Different letters indicate significant differences along the same column at p < 0.05. ples except t 0 , that showed a Newtonian behaviour (a constant trend) for all shears. In the third region, it was possible to observe an upper Newtonian region in which the viscosity (η∞), called the limiting viscosity at infinite shear rate, was constant with the changing of the shear rate (Aguilera and Stanley, 1999;Banerjee et al, 2010;Galindo-Rosales et al, 2010).…”
