The physical properties desired for various applications of aluminum alloys are usually modified by tailoring their precipitation behavior during heat treatment. In this study, the a cast Al–Mn alloy annealed with two heating methods (electric resistance and radiative furnace heating) at different temperature has been studied through electrical conductivity (EC) test, scanning electron microsco...

Inference on the extremal behaviour of spatial aggregates precipitation is important for quantifying river flood risk. There are two classes previous approach, with one failing to ensure self-consistency in inference across different regions aggregation and other imposing highly restrictive assumptions. To overcome these issues, we propose a model high-resolution data from which can simulate re...

hbs vaccines were prepared by three different methods: 1) heat inactivation (krugman, et.al 1971)2) ammonium sulphate precipitation followed by column chromatography (sephadex g-200) 3) peg-6000 (polyethylene glycol) precipitation followed by column chromatography using sephadex g-200. their efficacy was studied in guinea pigs, and the results compared with commercial japanese vaccine (green cr...
