Butyl rubber (polyisobutylene-co-isoprene (IIR)) is a very important commercial elastomer with many desirable physical properties, such as low air permeability and broad damping properties. The principal uses of this material are in the tire industry for the preparation of inner tubes and inner liners of passenger car tires. Despite these unique properties, there are some deficiencies associate...

Media spaces were designed to support informal as well as formal communication among remote users. We believe that these systems must be integrated into existing environments in a lightweight way, blending support for collaboration with the user's existing computer environment. This demonstration presents videoSpace, a software toolkit that facilitates the integration of live video into documen...

A new branching blend between two natural quadrics (circular cylinders/cones or spheres) in many positions is proposed. The blend is a ring shaped patch of a PN surface (surface with rational offset) parametrized by rational bivariant functions of degree (6, 3). General theory of PN surfaces is developed using Laguerre geometry and a universal rational parametrization of the Blaschke cylinder. ...

The automatic generation of volumes bounding the intersection of two implicit surfaces (isosurfaces of real functions of 3D point coordinates) or feature based volumes (FBV) is presented. Such FBVs are defined by constructive operations, function normalization and offsetting. By applying various offset operations to the intersection of two surfaces, we can obtain variations in the shape of an F...

SUMMARY Roller compacted hydrophilic polymer combinations were used to formulate verapamil hydrochloride (HCl) extended release hydrophilic matrix tablets. The effect of roller compaction (RC) parameters on the properties of blended polymers, tablets and drug release were investigated. RC granulation improved the powder properties without affecting the pharmacotechnical properties or the drug r...

Many social researchers measure multidimensional variables, such as rural leadership, by aggregating the scores of individual dimensions / sub-dimensions. These dimensions / sub-dimensions are highly correlated and have inherent problem of multicolinearity which causes attenuation in measurement. In order to overcome this problem, the M-K-J-B-D method developed by a group of researchers, has be...

carboxymethyl cellulose (cmc)-polyvinyl alcohol (pvoh) blend film was produced through casting. cellulose nanowhisker (cnw) was produced by means of acid hydrolysis of cotton linter and cmc-pvoh-cellulose nanowhiskers through which fully degradable bionanocomposites were prepared. prepared nanowhisker suspension contained rod like particles averaging lengths of 240 nm and diameters of 13 nm. an...

In this study, we successfully report an intimate ternary blend system of polycarbonate (PC)/poly(methyl methacrylate) (PMMA)/poly(vinyl acetate) (PVAc) obtained by the simultaneous coalescence of the three guest polymers from their common -cyclodextrin ( -CD) inclusion compound (IC). The thermal transitions and the homogeneity of the coalesced ternary blend were studied by differential scannin...
