STUDIES OF DESIGN OF HYDRAULIC JUMP TYPE STILLING BASIN IN LABORATORY FOR GUNJAWANI DAM, MAHARASHTRA, INDIA
Abstract: ABSTRACTThe water flowing over the spillway acquires a lot of kinetic energy by the time it reaches near the toe of the spillway. If precautionary measures are not made to dissipate this huge kinetic energy of water, large scale scour can take place on down-stream side near the toe of dam and away from it.The kinetic energy of this supercritical flow can be dissipated by converting supercritical flow into subcritical …

Optimization of Microbial Cellulose Production by the Newly Isolated Acetobacter sp. DR-1 under Laboratory Conditions
Abstract: Cellulose is the most abundant natural biopolymer on the earth, synthesized by plants, algae and also some species of bacteria. It is also produced by some animals (e.g., tunicates).Cellulose constitutes one of the three principal components present in plant, namely cellulose, hemi-cellulose and lignin. However, the degree of polymerization and crystallinity of bacterial cellulose is considerable high than that of plant cellulose. In microbes, cellulose is normally produced as exo-polysaccharide, …

Two Phase Retrial Queue Evaluation Using DEMATEL (Decision Making Trial and Evaluation Laboratory)
Abstract: In this study, retrial queues are characterized by calls that detect that all servers are busy joining the review team, and retrying their demands in random order and at random intervals. If the server is found to be busy, customers can join the review team at a random time. But they keep making the same demands, at random or at set intervals. Recurring queues are widely used to model many …

Petroleum Ether, A Laboratory Solvent Induced Cannibalism, Piloerection and Straub Tail Reaction in Rodents
Abstract: Petroleum ether is one of the most commonly used solvent in extraction of herbals/biological substances. In pharmacognostical studies, petroleum ether is used as a solvent for extract of herbals which was used for further pharmacological investigation. In a few of their studies, the authors have observed petroleum ether-induced piloerection which may be related to the herbal extract or trace solvent effect. Complete removal of petroleum ether solvent in herbal extract …
