a highly convenient, selective and sensitive procedure for pre-concentration, separation and determination of sub-ppm levels of cu 2+ in aqueous samples based on modification of octadecyl silica bonded phase membrane (osbpm) disks is described using benzildithiosemicarbazone  (bdsc) as a powerful modifier. it was revealed that each loaded osbpm disk with 6.0 mg of bdsc serves as excellent bead ...

We introduce a new parallelization framework for scientific computing based on BDSC, an efficient automatic scheduling algorithm for parallel programs in the presence of resource constraints on the number of processors and their local memory size. BDSC extends Yang and Gerasoulis’s Dominant Sequence Clustering (DSC) algorithm; it uses sophisticated cost models and addresses both shared and dist...

Vehicular ad hoc networks (VANETs) have potential applications for improving on-road driving experiences including preemptive road safety measures and provision for infotainment services. This paper proposes a Bi-directional Stable Communication (BDSC) relay nodes selection scheme designed for multi-hop broadcasting protocols over a platoon of vehicles. Relay nodes selection is based on quantit...

Nateglinide has been widely used in the treatment of type-2 diabetics as an insulin secretogoga. A reliable, rapid, simple and sensitive reversed-phase high performance liquid chromatography (RP-HPLC) method was developed and validated for determination of nateglinide in rabbit plasma. The method was developed on Hypersil BDSC-18 column (250 mm×4.6 mm, 5 mm) using a mobile phase of 10 mM phosph...

Benzildithiosemicarbazone (BDTSC) is proposed as a sensitive and selective analytical reagent for the extractive spectrophotometric determination of copper(II). BDTSC reacts with copper(II) in the pH range 1.0-7.0 to form a yellowish complex. Beer's law is obeyed in the concentration range 0.5-0.4 microg cm(-3). The yellowish Cu(II)-BDTSC complex in chloroform shows a maximum absorbance at 380 ...

This thesis intends to show how to efficiently exploit the parallelism present in applications in order to enjoy the performance benefits that multiprocessors can provide, using a new automatic task parallelization methodology for compilers. The key characteristics we focus on are resource constraints and static scheduling. This methodology includes the techniques required to decompose applicat...
