Development of a predictive model for polymer/solvent diffusion coefficient calculations

A new calculation procedure for free‐volume parameters is considered in this work by using viscosity prediction methods and the Levenberg‐Marquardt calculation scheme. All parameters used in the Vrentas–Duda free‐volume theory can be estimated from pure component properties. The prediction results are compared with experimental data for some polymer/solvent systems. The diffusion coefficient calculated by Vrentas–Duda theory can be used in the modeling of membrane separation processes. © 2008 Wiley Periodicals, Inc. J Appl Polym Sci, 2008

Lesbian homoerotic transference in dialectic with developmental mourning: On the way to symbolism from the protosymbolic.

This clinical study illustrates the developmental nature of homoerotic transference, when the psychoanalyst is attuned to the evolving dynamics of the mourning process, in this case with a lesbian analysand. The analysand's psychic fantasies of the female analyst as a muse and a demon lover figure are seen to transform into discrete mother and father transferences, as split off feminine and aggressive parts of the self are reintegrated along with heterosexual desires and oedipal desires. Protosymbolic enactments in terms of romantic gift giving and other seductive overtures transform into symbolic expressions of love, concern, regret, and tenderness. A lesbian marriage is preserved, and the loss of intimacy with men is mourned so that desires for intimacy with men can be sublimated.

A multi-criterion interaction-oriented model with proportional rule for designing supply chain networks

Supply chain management has offered a way to improve the industrial environment becomes more competitive. While, the commonly seen methodologies may be effective in solving the production–distribution problem only from supplier- or customer-oriented consideration, those cannot present the interactive relationship between upstream and downstream enterprises. In the competitive semiconductor industry environment, considering the viewpoints of the supplier and consumer simultaneously is particularly required, because multiple manufacturing and demanding steps are performed at separate situations, concurrently. In this paper, we propose an interaction-oriented approach, which bases on the analytic hierarchy process (AHP) methodology and proportional rule, to solve the semiconductor distribution problem with multiple quantitative and qualitative criteria. The developed approach gives an expected satisfaction for the all participators of the whole chain while the cooperative information is shared perfectly and effectively. Analysis results demonstrate the proposed methodology is efficient and effective through a real world case study.
