A study was conducted to compare tissue displacement resulting from different techniques and impression materials for distal-extension ridges. Impression techniques used were Applegate's functional fluid wax and a single-impression technique with mercaptan rubber. A mucostatic impression technique using irreversible hydrocolloid served as control. The results showed a statistically significant ...

stabilizers have been used to improve the texture of ice cream for several decades. they added it to ice cream to control ice and lactose crystal growth during hardening and storage, to give body and stiffness during freezing for air incorporation and to impart smoothness in body and texture. nowadays, most of the industrial stabilizers are provided from abroad, so, extraction, determination of...

Xanthan gum and scleroglucan, two rod-like polysaccharide hydrocolloids, are compared using a wide range of instrumental techniques methods: steady shear flow, small amplitude oscillatory shear, first normal stress difference, capillary break-up soft-contact tribology. The aqueous solutions these hydrocolloids with similar flow viscoelastic profile show marked differences in time apparent exten...

in this work attempts were made to evaluate k+-sds and hydrocolloid polymer-sds interactions in flocculation of megestrol acetate dispersions to enhancetheir stability as a part of suspension formulation. different dispersions of micronized megestrol acetate and sds were prepared. kcl and kh2po4 and their corresponding sodium salts were added to the dispersions and the preparations were evaluat...
