Focused open-vessel microwave-assisted extraction (FOV-MAE), closed-vessel microwave-assisted extraction (CV-MAE), and accelerated solvent extraction (ASE) were used for extraction before determination of organochlorine compounds (polychlorinated biphenyls, DDT, toxaphene, chlordane, hexachlorobenzene, hexachlorocyclohexanes, and dieldrin) in cod liver and fish fillets. Wet samples were extract...

Storing of available energy for later use is a necessity in the present world, one such method is using Phase Change Materials (PCMs). PCMs need a heat transfer medium to transfer the energy from the source to the PCM. In this present work spherical balls are used to store the PCM and water is used as a heat transfer fluid. Paraffin wax (PW) and Palmitic acid (PA) and (4060% PW-PA) eutectic mix...

The effect of dry material, glycerol and ratio of water to seed in alyssum homalocarpum films on their thickness, transparency, moisture content, tensile strength, elongation and water vapor permeability was investigated using mixture response surface methods. Dry material and glycerol were important factors influencing tensile strength, elongation and water vapor permeability. Ratio of water t...

The research presented in this thesis is concerned with the flow behaviour of two-phase, liquid-liquid, oil-water flow through horizontal pipes. The test liquids used were oil (density 828kg/rn 3, viscosity 6x iO 3 Pa s) and water, with experiments carried out in a purpose built test facility with a stainless steel pipe (internal dia. 38mm, length 8m). Visual observation of the flow was possibl...

200 ml. of isopropenyl acetate (Tennessee Eastman Corporation) are cooled in an ice bath and then, with stirring, 25 ml. of 85 per cent syrupy phosphoric acid (35 gm. of H3P04) are added dropwise, and finally 1.0 ml. of concentrated sulfuric acid is added as catalyst. The reaction mixture is placed in a water bath at 25” and stirred constantly to prevent localized heating. After 35 minutes at t...

Finite mixture models, that is, weighted averages of parametric distributions, provide a powerful way to extend parametric families of distributions to fit data sets not adequately fit by a single parametric distribution. First-order finite mixture models have been widely used in the physical, chemical, biological, and social sciences for over 100 years. Using maximum likelihood estimation, we ...
