several studies have shown that oil recovery significantly increased by low salinity water flooding (lswf) in sandstones. however, mechanism of oil recovery improvement is still controversial. co2 that develops buffer in presence of water is expected as a deterrent factor in lswf efficiency based on mechanism of ift reduction due to ph uprising. no bright evidence in literature supports this id...

Several studies have shown that oil recovery significantly increased by low salinity water flooding (LSWF) in sandstones. However, mechanism of oil recovery improvement is still controversial. CO2 that develops buffer in presence of water is expected as a deterrent factor in LSWF efficiency based on mechanism of IFT reduction due to pH uprising. No bright evidence in literature suppo...

This study used the general applicability of 2,6-didi-o-methyl-β-cyclodextrin (DM-β-CD) as the chiral selector in capillary electrophoresis for fast and efficient chiral separation of repaglinide enantiomers. A systematic study of the parameters affecting separation was performed with UV detection at 243 nm. The optimum conditions were determined to be 1.25% (w/v) DM-β-CD in 20 mM sodium phosph...

Personal communications and mobile computing will require a wireless network infrastructure which is fast deployable, possibly multihop, and capable of multimedia service support. The first infrastructure of this type was the Packet Radio Network (PRNET), developed in the 70’s to address the battlefield and disaster recovery communication requirements. PRNET was totally asynchronous and was bas...

Networks using wormhole switching have traditionally relied upon deadlock avoidance strategies for the design of deadlock-free routing algorithms. More recently, deadlock recovery strategies have begun to gain acceptance. In particular, progressive deadlock recovery techniques are very attractive because they allocate a few dedicated resources to quickly deliver deadlocked packets, instead of k...

We have investigated the citation impact of four pairs of journals in four subject categories including the category of multidisciplinary journals, journals in environmental sciences, applied mathematics, as well as metallurgy and metallurgical engineering. Each pair is composed of one Chinese journal and one leading international journal in the same subject category. Comparison is done between...

Implementation of a supply-chain (SC) system has crucial impacts on a company's financial performance. Overall performance of a SC network is influenced significantly by the decisions taken in its production-distribution plan which integrates the decisions in production, transport and warehousing as well as inventory management. Thus, one key issue in the current research area of performance ev...

This review is focused on the strategies and designs of magnetic nanostructured catalysts showing the enhanced and sustainable catalytic performances for the heterogeneous reduction of nitoaromatics. Magnetic catalysts have the benefits of easy recovery and reuse after the completion of the reactions and green chemical processes. Magnetic separation, among the various procedures for removing ca...
