Metropolitan area ring networks can be categorized into metro edge and metro core rings. The traffic characteristics of metro edge and metro core rings are quite different. While metro edge rings exhibit a strongly hubbed traffic pattern (hot spots), traffic demands in metro core rings are much more uniform. We examine the throughput-delay performance of a buffer insertion ring with destination...

Tin anode slime is a by-product of the tin electrolytic refining process. This study investigated route to separate Sn, Sb, Bi, and Cu from after leaching with hydrochloric acid. In solvent extraction process tributyl phosphate, Sb Sn were extracted into organic phase. Bi unextracted remained in liquid stripping experiment, stripped separated HCl HNO3. aqueous phase also chemical precipitation ...

Iron is the major impurity in pregnant leaching solutions (PLS) derived from heap and atmospheric acid of low-grade laterite ores. The PLS can be considered as a secondary resource for synthesis high added-value iron nanomaterials, provided that selectively separated polymetallic solution. In this study, feasibility selective separation was investigated by applying solvent extraction technique ...

Electrochemical stripping analysis (ESA) is a trace electroanalytical technique for the determination of metal cations, inorganic ions, organic compounds and biomolecules. It based on pre-concentration step target analyte(s), or compound target, suitable working electrode. This followed by accumulated analyte using an technique. Advantages ESA include high sensitivity low limits detection, mult...

This is a review of analytical methods, such as spectrophotometry, derivative spectrophotometry and various chromatographic (gas chromatography-GC, high-performance liquid chromatography-HPLC, thin-layer chromatography-TLC, high-performance thin-layer chromatography-HPTLC, liquid chromatography-tandem mass spectrometry-LC-MS, microchip electrophoresis-MCE, capillary electrophoresis-CE) and elec...

We report a "ligand stripping" method for the creation of secondary structures of colloidal nanocrystals. Using iron oxide as an example, we demonstrate that the use of diols as "stripping agents" allows the controllable removal of the original capping ligands and induces aggregation of nanocrystals into well-defined clusters.

Granisetron showed one well-defined reduction peak at Hanging Mercury Drop Electrode (HMDE) in the potential range from -1.3 to -1.5 V due to reduction of C=N bond. Solid-phase extraction technique was employed for extraction of Granisetron from spiked human plasma. Granisetron showed peak current enhancement of 4.45% at square-wave voltammetry and 5.33% at cyclic voltammetry as compared with t...
