A method has been developed for the solid phase extraction of chromium(VI) based on the adsorption of its diphenylcarbazide complex on an Amberlite XAD-4 resin column. The influence of acidity, stability of the column, sample volume, flow rate and interfering ions were studied in detail. The adsorbed complex could be eluted using acetone-sulfuric acid(More)
Multi-core based systems are ubiquitous in data centers. Efficient exploitation of hardware parallelism supported by such systems is imperative on multiple fronts: minimizing latency and power consumption and maximizing throughput. This in turn calls for advanced program analysis and optimization. Call graphs have been long used to this end. Although(More)
