We present a new interactive paradigm for iterative information retrieval based on the automatic construction of a faceted representation for a document subset. Facets are chosen heuristically based on lexical dispersion, a measure of the number of different terms with which a word co-occurs within noun phrases appearing in the document set. The phrases in which these terms occur serve to provi...

The article describes a case in which a popliteal cyst was identified presenting as a mass on the anterior aspect of theright tibia. This occurred as a result of polyethylene wear debris from previous total knee arthroplasty. Although alternativediagnoses for an anterior tibial mass are more likely, a popliteal cyst must be considered, particularly if the patient has ahistory of total knee arth...

AIMS The effects of adrenergic activity and beta-blockade were studied in a canine experimental model of type-3 long QT syndrome (LQT3) induced by application of anthopleurin-A. METHODS AND RESULTS Boluses of epinephrine at 0.5 and/or 1.0 microg/kg were administered before and after propranolol, 0.3 mg/kg, and the distribution of the ventricular repolarization and the development of polymorph...

The ever increasing pile-up of electronic waste in dumping sites, especially in developing countries such as China, Pakistan, India and several African countries, might have caused a significant alteration in the microbial community of the contaminated sites. This change in the microbial population may have significant impact to the soil ecology function. The major pollutants of electronic wast...

an extensive study of fischer-tropsch synthesis (fts) on alumina-supported cobalt catalysts with different amounts of cobalt is reported. up to 40 wt % of cobalt, is added to the catalysts by impregnation method. the effect of the cobalt loading on the reducibility of the cobalt oxide species, dispersion of the cobalt, average clusters size, water-gas shift (wgs) activity and activity and selec...

The cysteine-rich 8K protein of Potato mop-top virus (PMTV) suppresses host RNA silencing. In this study, evolutionary analysisof 8K sequences of PMTV isolates was studied on the basis of nucleotide and amino acid sequences. Twenty-one positively selected sites were identified in 8K codingregions. Recombination events were found in the 8K of PMTV isolates with a rate of 1.8. Totally 30 haplotyp...

UNLABELLED To study the role of the dispersion of atrial repolarization (DAR) in the genesis of atrial fibrillation (AF), monophasic action potentials (MAP) were recorded simultaneously from a catheter at the high lateral right atrium (HLRA) and a catheter moving around the high, middle and low lateral right atrium (RA) the high, anterior and posterior septal RA and the RA appendage in 15 patie...
