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...

Method comparison studies of two different methods for the analysis of weak acid dissociable (WAD) cyanide revealed analytical flaws and/or matrix interference problems with both procedures. EPA "draft" method 1677 using a Perstorp 3202 CN analyzer was compared to Standard Method 4500 CN I. It was discovered that the Perstorp analyzer produced more precise and more accurate results once appropr...

STUDY OBJECTIVE To examine the association between damp housing and adult health, taking into account a wide range of other factors that may influence health and could confound this relation. PARTICIPANTS AND SETTING A general population sample of adults, aged 18-64, from Oxfordshire, Buckinghamshire, Berkshire and Northamptonshire. DESIGN Secondary analysis of responses to a postal questio...

Polymerase eta is a member of the Y family of DNA polymerases which is able to bypass thymine dimers efficiently and in a relatively error-free manner. To elucidate the mechanism of dimer bypass, the efficiency of dAMP and pyrene nucleotide insertion opposite the thymine dimer and its N3-methyl derivatives was determined. Pol eta inserts pyrene nucleotide with greater efficiency than dAMP oppos...

The changes of defect characteristics induced by accelerated lifetime tests on solar cells of the heterostructure ZnO/CdS/Cu(In,Ga)(S,Se)2/Mo are investigated. Encapsulated modules were shown to be stable against water vapor and oxygen under outdoor conditions, whereas the fill factor and open-circuit voltage of non-encapsulated test cells are reduced after prolonged damp-heat treatment in the ...
