Managing Medicaid managed care: are states becoming prudent purchasers?

Autor: J W, Fossett, M, Goggin, J S, Hall, J, Johnston, L C, Plein, R, Roper, C, Weissert

Publikováno v: Health affairs (Project Hope). 19(4)

This paper examines the extent to which five states are becoming "prudent purchasers" in their oversight of Medicaid managed care. Our conclusions are mixed. These states are making more sustained efforts along these lines than most private purchaser

Heterogeneous Polymer Blends II. Physical Properties of Binary Elastomer Composites

Autor: F. C. Weissert, G. N. Avgeropoulos

Publikováno v: Journal of Elastomers & Plastics. 9:102-119

Tensile properties of two-phase elastomer-elastomer vulcanizates were measured and evaluated in terms of the initial number average molecular weight (Mn), the crosslink density (veff) and the glass temperatures (Tg's) of the composite. Interpretation

Publikováno v: Angewandte Makromolekulare Chemie. 60:49-86

The morphology of heterogeneous blends of polybutadiene (PBD) and EPDM was selectively varied by a change of either the rheology of the blend components during mixing or of the blend composition. Under a given set of mixing conditions, the blend syst

Modelling of Shear Viscosity Behavior and Extrusion through Dies for Rubber Compounds

Autor: Nobuyuki Nakajima, James L. White, Frederick C. Weissert, Kyonsuku Min, Yeh Wang, Avraam I. Isayev

Publikováno v: Rubber Chemistry and Technology. 60:337-360

This paper marks a first effort to develop a fundamental basis for die flow analysis and design for rubber compounds. We have accomplished a modelling of the shear viscosity function and its application to one- and two-dimensional shearing in die cro

A Rheo-Optical Study of the Influence of Additives on Crystallization Rates in Cis-1,4 Polyisoprene

Autor: James L. White, Frederick C. Weissert, Kyonsuku Min, Nobuyuki Nakajima, Yun-Jin Chen

Publikováno v: Rubber Chemistry and Technology. 61:324-339

A rheo-optical study of the influence of additives on crystallization rates in synthetic cis-1,4 polyisoprene (IR2200) at room temperature is presented. Nine different additives at a 1% concentration were examined. This study has found many additives

Experimental and Theoretical Study of the Flow Characteristics of Rubber Compounds in an Extruder Screw

Autor: James L. White, Kyonsuku Min, Frederick C. Weissert, Kazuhisa Kubota, Ryszard Brzoskowski, Nobuyuki Nakajima, Kiho Chung

Publikováno v: International Polymer Processing. 1:130-136

We describe an experimental and theoretical study of the mechanisms of flow of rubber compounds in a screw extruder. Two compounds, a typical synthetic rubber (butadiene-styrene copolymer-cis-1, 4 polybutadiene) based passenger tire tread (PTT) and a

Flow Patterns in Elastomers and Their Carbon Black Compounds during Extrusion through Dies

Autor: James L. White, Frederick C. Weissert, Avraam I. Isayev, Nobuyuki Nakajima, Chin-Yuan Ma, Kyonsuku Min

Publikováno v: Rubber Chemistry and Technology. 58:815-829

A basic study of flow patterns in elastomers in the entrance region of a die has been carried out for various gum elastomers including emulsion and solution butadiene—styrene copolymers, polybutadiene, and natural rubber. All exhibit streamline flo
