A prominent Anglo-indian‚ Derozio played a major role in introducing western attitudes into Indian intellectual life. He taught literature and history at Hindu College‚ Calcutta and was perhaps the first nationalist poet of modern India. Drawing inspiration from French Revolution‚ he inspired his pupils to think freely and rationally‚ question all authority‚ oppose meaningless customs and traditions. He started a discussion group—the Academic Association—to enable interaction amongst students. He

Chem 107 HW 8 (16‚ 26‚ 32‚ 38) 16. Determine how much energy is released or required for the reaction shown. Is this reaction exothermic or endothermic? CO2 + 2 H2O → CH4 + 2 O2 This reaction is endothermic 26. Why can’t we digest fiber? We cannot digest fiber because we lack the enzyme capable of breaking the sugar linkages in cellulose. 32. Why is unsaturated fat considered much healthier than saturated or trans fat? Unsaturated fat provides benefits of fat in the diet without the risk

F1-F4: Emulsion Solvent Diffusion Method (ESD) The microparticles of formulations from F1-F4 which are prepared by ESD method were irregularly spherical in shape. The percentage yield increased with increase in polymer concentration from 88.3 to 93.6%. Stirring speed does not show any valid effect in the percentage of yield. Particle size increased with increase in the polymer concentration due to the viscosity character of the polymer which comes in contact with the drug to form microparticles
