Virtual and Augmented Reality Simulation of Chattanooga Creek

Virtual reality involves reproducing all the details of a physical object or environment that has to be simulated in virtual space. Augmented reality is the mixing of computer-generated information with the user’s view of the real world. Augmented reality is an alternative for virtual reality. This thesis presents the interactive virtual reality simulation and augmented reality simulation of Chattanooga Creek in Chattanooga, TN. The augmented reality part involves implementation of the basic concept of augmenting the virtual graphics to the real world

Simple and sensitive spectrophotometric methods for the analysis of mesalamine in bulk and tablet dosage forms

Three simple, sensitive, economical and reproducible spectrophotometric methods (A, B and C) are described for determination of mesalamine in pure drug as well as in tablet dosage forms. Method A is based on the reduction of tungstate and/or molybdate in Folin Ciocalteu's reagent; method B describes the reaction between the diazotized drug and α-naphthol and method C is based on the reaction of the drug with vanillin, in acidic medium. Under optimum conditions, mesalamine could be quantified in the concentration ranges, 1-30, 1-15 and 2-30 µg mL-1 by method A, B and C, respectively. All the methods have been applied to the determination of mesalamine in tablet dosage forms. Results of analysis are validated statistically
