A Review on Novel Emulsification Technique: A Nanoemulsion
Poor water solubility remains main culprit for the formulation scientist which can be overcome by nanonization. Nanoemulsion is kinetically stable and isotropic system of two immiscible liquids in sub microne size range. Nanoemulsions are composed of oil droplets dispersed in an aqueous medium and stabilized by surfactant molecules. Advantages of nanoemulsions include increased drug loading and...
متن کاملDevelopment of nanoemulsions by an emulsification-evaporation technique
The aim of this study was to investigate the preparation of oil-in-water (O/W) nanoemulsions using an emulsification–evaporation process. Nanoemulsions were formed by homogenizing 10 wt% of an organic phase composed by corn oil and hexane mixed at different ratios, and 90 wt% emulsifier solution containing 1.0 wt % of Tween 20 (T20) or β-lactoglobulin (β-Lg). Nanoemulsions were prepared using a...

In recent years, it has become increasingly fashionable to attribute a myriad 0f our economic and social difficulties to excessive government regulation. If we are to believe the rhetoric, government regulation is partly or largely to blame for soaring inflation, lagging growth in GNP, declining productivity growth, the decline in the value of the dollar, and even general reductions in the anim...
متن کاملProgress on a Mathematical Inversion Technique for Non-Destructive Evaluation
Last year, computer output was presented for synthetic pulse-echo data which was processed according to a mathematical imaging technique. This technique was based on the physical optics farfield inverse scattering (acronym, POFFIS) formalism for scattering by volume defects. This year, a number of theoretical advances have been made in the POFFIS formalism, with attendant revisions in the compu...
متن کاملPoor (Wo)man’s Bootstrap∗
The bootstrap is a convenient tool for estimating standard errors of the parameters of complicated econometric models. Unfortunately, the fact that these models are complicated often makes the bootstrap extremely slow or even practically infeasible. This paper proposes an alternative to the bootstrap which is only based on estimation of one-dimensional parameters. The paper contains no difficul...
