a semi-empirical mathematical model for predicting physical part of ignition delay period in the combustion of direct - injection diesel engines with swirl is developed . this model based on a single droplet evaporation model . the governing equations , namely , equations of droplet motion , heat and mass transfer were solved simultaneously using a rung-kutta step by step unmerical method . the...

Anticonvulsant and Antimicrobial Activity of Cu (II), Zn (II) and Co (II) Complex of Isatin 3-Glycine

      The role of Cu, Zn and Co in human physiology is well documented. Isatin and glycine have inhibitory effects on central nervous system. To capitalize on these features metal complexes of isatin-3-glycine were prepared and evaluated for anticonvulsant activity. The Cu (II) complex was found to be most active among the compounds. The compounds were screened against Staphylococcus aureus...
