The deviations observed between the experimental and theoretical values of diffusion coefficients are explained by considering different types of interactions occurring in the ion-gel water system. The applicability of the transition state theory to the diffusion of ZnSO4 in agar gel medium is tested by varying the temperature as well as the gel concentration at high concentration of the electrolyte. The activation energy E and D 0 value decrease with increasing gel concentration in agreement with the theory.

The divergence observed between theoretical and experimental values of diffusion coefficients in both systems is explained on the basis of various types of interactions occurring in the system.

This is achieved by classifying the plants in four groups based on the increasing level of manufacturing strategy implementation using cluster analysis. The paper also highlights managerial implications, limitations and future scope of research.

Though the companies differ in terms of product types (shape, method, content and material of packaging), conversion system, sales volume and sophistication of machinery used, they share common purpose that are used for packaging the products. With growth in demand for consumer products, packaging forms basis of differentiating products from competitors. The survey shows emphasis on implementation of manufacturing strategy, key decision areas, identifies competitive priorities, order winners. To get insight, three companies are selected for detailed case studies.

Effect of various experimental parameters has been investigated at 39±1°C under batch adsorption technique. The result shows that cotton stem activated carbon adsorbs dye to a sufficient extent. The physicochemical characterization and chemical kinetics was also examined for the same dye. The overall result shows that it can be fruitfully used for the removal of dye from wastewaters.

The deviations from the theoretical values obtained in these results are explained by considering ionic hydration, complex formation and ion-ion interactions. Further, these results are compared with the previously obtained results in gel medium; the contribution of gel molecules causing deviation from the theoretical value is estimated at various concentrations of the electrolyte and appropriate explanation is offered.

Decisions in process technology improve manufacturing outputs (Miltenburg, 2008). It is necessary to understand the implications of process technology for manufacturing cost, quality, delivery, flexibility, performance, and innovativeness to develop successful manufacturing strategy. This case study assesses process technology decisions compared with the competition in a packaging product manufacturing company in India.
