Silent Submarine Propulsion with High-Efficiency Magnetohydrodynamic Drive
Abstract: Magnetohydrodynamic (MHD) propulsion is an exciting technology that can be easily incorporated into a new submarine or existing one can also be upgraded by replacing the propeller drive with a MHD drive without difficulty. This new technology would provide many advantages like a stealth operation, no cavitation, greater maneuverability, increased payload, addition of an emergency drive system, etc. The design of an MHD motor is very simple and consists of …

Valorization of shrimp processing waste by green methodology and its application in Chitosan-PEG composite film
Abstract: Shrimp processing waste is mostly unidentified marine by product, presents considerable environmental pollution which also offers a rich but not fully exploited sources of biopolymers. The current work presents a sustainable method to convert shrimp processing waste into chitosan a biopolymer by green methodology. Isolation of chitin to chitosan from shrimp processing waste was carried through four green methodology steps i. Demineralization using citric acid ii. Deproteinization using papain iii. …
