The Box-Behnken design of experiments under response surface methodology (RSM) was used to optimize the foaming process for the development of foam mat-dried muskmelon powder. The independent variables were the concentration of egg albumen (EA), carboxymethyl cellulose (CMC) and whipping time (WT). The responses were foam density, foam drainage volume and foam expansion. The optimum conditions for foaming process were EA (11.59% w/w), CMC (0.59% w/w) and WT (3.97 min). The unfoamed muskmelon pulp took longer time to dry to the final moisture content of 2% d.b than foamed pulp. The effective diffusivity for the foamed muskmelon pulp was found to be higher than the unfoamed pulp. The unfoamed pulp resulted in a sticky and dark colored powder, whereas the foamed pulp had a free-flowing and light colored powder. The flaky and porous foam-dried product can be used as an ingredient in broad range of food products.

Corrosion inhibition nature of Colocid dye on the corrosion of mild steel in acid media was analyzed using weightloss and electrochemical methods. The results of electrochemical and weightloss studies indicated that Colocid acid could act as a potential inhibitor for mild steel in acid media. It has been observed that the inhibition efficiency increases with inhibitor concentration and the inhibition efficiency of Colocid acid dye for the corrosion of mild steel in 1.0 M HCl solution is larger than that in 0.5 M H 2 SO 4 solution.Potentiodynamic polarization studies showed that the dye molecule is of mixed type inhibitor. The adsorption of the compound on the mild steel surface obeyed Langmuir adsorption isotherm. The potential of zero charge was measured to find corrosion inhibition mechanism in these media.

An attempt was made to use the waste water from textile industry for construction purpose, so that the shortage in water can be greatly reduced and the waste water can be suitably disposed for safe guarding the environment. The basic properties of the treated and untreated water from the textile industry were tested and the results were found to be satisfactory such that it can be used for construction purposes. By using the waste water from the textile industry cubes, cylinders and beams were casted and tested for its mechanical properties (compressive strength, tensile strength, flexural strength etc) and the result was found to be satisfactory. Hence the experiment was continued on for durability studies where the corrosion attack was also studied. The results of other durability studies were found to be satisfactory. In this experimental study the results of specimen's casted using treated and untreated textile water were compared with the specimens casted with potable water. Since there was some corrosion, admixtures were added to counter act the same and the results were found to be satisfactory.
