Due to the isotropy and high thermal conductivity of metal foam, a novel idea isothermal chamber filled with graded copper foam (GCF) is developed improve characteristic chamber. Firstly, an analytical effective (ETC) prediction model proposed, relative root-mean-square error (RRMSE) 6.90%, which has higher ETC accuracy than semi-empirical models in literatures. Secondly, conventional porous ra...

alkaline hydrolysis of ethyl acetate is essentially an irreversible and second order reaction. industrial importance of the reaction product, sodium acetate, necessitate for process improvement in terms of maximum conversion and economical usage of raw materials. statistical design of experiments was utilized to enhance conversion in both batch and plug flow reactors.a full two level factorial ...

In 16 patients with hypertrophic cardiomyopathy, an acute response of the left ventricular end-diastolic pressure and volume index to intravenously administered verapamil was assessed. Verapamil decreased the left ventricular end-diastolic pressure from 20 +/- 6 to 17 +/- 5 mm Hg(p less than 0.001) and increased the end-diastolic volume index from 82 +/- 22 to 91 +/- 23 ml/sqm (p less than 0.01...
