Microbial degradation of petroleum hydrocarbons is one of the major practices in natural decontamination process. The present study investigated about the isolation of bacteria from crude oil contaminated site and gravimetric analysis of degradation in which, two bacterial isolates formed maximum clearing zone on mineral salt medium. Among these isolate S2 showed maximum growth (0.85mg/ml) and ...

STUDY OBJECTIVES The function of jet nebulizers has been measured traditionally by gravimetric methods, i.e., by weighing nebulizers before and after nebulization. Newer techniques measure aerosol output directly by analyzing aerosolized drug or tracer, i.e., radioactive 99mTc. Because of evaporation, the equivalence of these methods is uncertain. The aim of this study was to determine if the g...
