In Experiment I observers made color matches using three different adjustment control methods. The results showed that the Lightness, adjustment controls elicited significantly better performance than the display(More)
Viscoelasticity is a useful parameter for characterizing the intrinsic properties of the cross-linked polyacrylate hydrogel used in cataplasm bases. The aim of this study was to investigate the effects of various formulation parameters on the rheological characteristics of polyacrylate hydrogel. The hydrogel layers were formed using a partially neutralized(More)
