In recent years there has been renewed activity in the literature concerning the 1,3-dipolar cycloaddition reaction (1,3-DCR) of organic azides (R-N₃) with alkynes (R'-C≡CH) to form 1,2,3-triazoles, i.e. the Huisgen synthesis. The use of catalytic Cu(I) leads to a dramatic rate enhancement (up to 10(7)-fold) and exclusive synthesis of the 1,4-disubstituted 1,2,3-triazole product. The reaction, ...

Branding has become immensely important for digital based organizations in the recent years because electronic Re tailing are identical and difficult to differentiate their product services is highly attracting public, make use of organization especially E-Tailing. Customer play an role, with increased competition Electronic Retailing sector, For that, developing implementing customer centric s...

In addition to the Poiseuille effect, a so-called temporal effect was proposed recently to elucidate the commonly observed tailing peak signals of flow injection analysis (FIA). A multi-channel absorbance detector was used in this study to obtain the FIA peaks on both the spatial and temporal coordinates. The temporal effect was analyzed by comparison of the profiles between the experimental an...

A pot experiment was conducted to investigate the feasibility of growing energy sugarcane (Saccharum spp.) in three different metal mine tailings (Cu, Sn and Pb/Zn tailings) amended with uncontaminated soil at different mixing ratios. The results indicated that sugarcane was highly tolerant to tailing environments. Amendments of 20% soil to Sn tailings and 30% soil to Cu tailings could increase...

The present paper introduces the steel production and BOF slag processing techniques in Steelmaking Sector of Bayuquan Iron and Steel Subsidiary, Ansteel. The technology of slag tailings utilization has been developed under the consideration of the properties of slag tailing and the characteristics of slag forming in BOF steelmaking operation practice. The processing of the BOF slag includes ho...

The Internet’s influence in creating e-services has been revolutionary for retailer. Clearly, The Internet is fast becoming an important new channel for businesses in retailing, raising e-services as the emergent business paradigm in the industrialized world. Unfortunately, past research on measuring e-tailing quality is scarce. This paper provides a conceptual framework for e-tailing quality a...

Online restricted access media with liquid chromatography and tandem mass spectrometry for the direct analysis of small molecules in biological fluids represents an interesting alternative to time-demanding traditional sample preparation techniques. In this study, important considerations concerning the development of a restricted access media with liquid chromatography and tandem mass spectrom...

Pfu DNA Polymerase(a)-generated blunt-end PCR fragments can be ligated into the pGEM®-T and pGEM®-T Easy Vectors(b,c) if the fragments are first A-tailed using Taq DNA Polymerase(a). We describe a method for A-tailing these PCR fragments and demonstrate its utility by cloning two different Pfu DNA Polymerase-generated fragments into the pGEM®-T Easy Vector, using the new 2X Rapid Ligation Buffe...
