Risk factors for complications after colonic stent insertion for large bowel obstruction
This journal suppl. entitled: DDW 2014 ASGE Program and AbstractsBACKGROUND: Colonic stenting is proven to be an effective means in relieving malignant large bowel obstruction. However, severe complication such as perforation of bowel and subsequently fecal peritonitis can occur after successful of insertion of colonic stent. While colonic stenting is practiced more widely, concern also arises as a result of reports on increased complication rate from this procedure ...postprin
Automated Targeting for Property Integration
Resource conservation is an effective way for reducing operation cost and to maintain business sustainability. Most previous works have been restricted to "chemo-centric" or concentration-based systems where the characterisation of the streams and constraints on the process sinks are described in terms of the concentration of pollutants. However, there are many applications in which stream quality is characterised by physical or chemical properties rather than pollutant concentration. In this work, the automated targeting approach originally developed for the synthesis of composition-based resource conservation network is extended for property-based network. Based on the concept of insight-based targeting approach, the automated targeting technique is formulated as a linear programming (LP) model for which the global optimum is guaranteed. Two literature examples are solved to illustrate the proposed approach
Nature of Correlated Motion of Electrons in the Parent Cobaltate Superconductors
Recently discovered class of cobaltate superconductors (Na0.3CoO2.nH2O) is a
novel realization of interacting quantum electron systems in a triangular
network with low-energy degrees of freedom. We employ angle-resolved
photoemission spectroscopy to uncover the nature of microscopic electron motion
in the parent superconductors for the first time. Results reveal a large
hole-like Fermi surface (consistent with Luttinger theorem) generated by the
crossing of super-heavy quasiparticles. The measured quasiparticle parameters
collectively suggest a two orders of magnitude departure from the conventional
Bardeen-Cooper-Schrieffer electron dynamics paradigm and unveils cobaltates as
a rather hidden class of relatively high temperature superconductors.Comment: 5 pages, 4 figures, 1 tabl
