The remediation of groundwater contamination by pumping and injection is generally a long-term and costly strategy. Aquifer cleanup time is a highly nonlinear and nonconvex function of pumping rates. The cleanup objective often involves minimizing or constraining the cleanup time or cleanup cost. Linear programming and nonlinear optimization cannot guarantee the global solution. In this study, ...

An R&D division of the National Library of Medicine (NLM) has developed the Web-based Medical Article Records System (WebMARS) to create citations from online biomedical journals. This paper presents one important part of this system, the automated cleanup module that extracts bibliographic information from HTML-formatted text based on a rule-based approach. A learning scheme comparing the outp...

A procedure to immunoaffinity purify the human transcription factor IIH (TFIIH) was developed using a monoclonal antibody that recognizes an epitope in ERCC3 (XPB), the largest subunit of TFIIH. The epitope recognized by the monoclonal antibody was mapped to 20 amino acids. A peptide containing the epitope was capable of displacing TFIIH from an immunoaffinity column containing the monoclonal a...

Oil sorbents play a significant role in the treatment processes of oil spills, therefore, enhancing oil-water separation capacity has been charming consideration scientific researchers. To improve properties sorption and simplify process recovery, many advanced sorbent devices have projected recently. Different types materials are used as for separation, however, up to now, there is no review p...

This article charts the history of bioethics in Britain through the work of the academic lawyer Ian Kennedy. From the late 1970s, Kennedy claimed that external oversight, which he termed ‘bioethics’, was needed to make medicine accountable to patients and the public. I believe these arguments provide a window onto the historical factors that generated the demand for bioethics, and help us deter...

The use of volatile organic compounds (VOCs) in lithographic printing cleanup is an environmental and occupational hazard. Regulations to reduce ambient ozone levels limited VOC emissions from lithographic cleanup operations and spurred the development of low-VOC alternatives. The purpose of this project was to promote the substitution of hazardous cleanup solvents with less toxic chemicals to ...

This research is the first to quantify complex PAH mixtures in NIST SRMs using comprehensive two-dimensional gas chromatography coupled to time-of-flight mass spectrometry (GC×GC/ToF-MS), with and without extract cleanup, and reports previously unidentified PAH congeners in the NIST SRMs. We tested a novel, high orthogonality GC column combination (LC-50×NSP-35), as well as with a commonly used...

A combination of ELISA, Western blotting and immunoaffinity concentration using an anti-ginsenoside Rb1 monoclonal antibody was applied for qualitative and quantitative surveys of ginsenoside Rb1 and related ginsenosides in roots and traditional Chinese herbal medicines. To improve the low correlation between ELISA and HPLC analysis, the crude extract of roots was immunoaffinity concentrated to...

Unless an all quadrilateral (quad) finite element mesher is of a high quality, the mesh it produces can contain misshapen quads. This paper will describe “CleanUp”, written to improve an all quad mesh. CleanUp looks at improving node connectivity, boundary and flange patterns, quad shape, and to some extent, quad size. CleanUp is currently used in conjunction with the Paver algorithm developed ...
