OBJECTIVE To determine whether ranitidine bismuth citrate, clarithromycin, or a combination of ranitidine bismuth citrate and clarithromycin would be efficacious in eradication of Helicobacter mustelae infection in ferrets. ANIMALS 60 seven-month-old ferrets. PROCEDURE To determine dosages of clarithromycin and ranitidine bismuth citrate that would suppress growth of, but not eradicate infe...

Bismuth&d platinum electrodes were investigated as pH indicating electrodes in strong KOH solutions (pH 14-16). The E-pH curve of freshly prepared bismuth electrodes is linear, but the E-pH slope altered with time. It is shown that the slope is constant if the bismuth electrode has been aged via immersion in a concentrated KOH solution. The value of the E-pH slope depends on the KOH concentrati...

PURPOSE To compare the dose and image quality of three methods for reducing the radiation dose to the eye at head computed tomography (CT): bismuth shielding, organ-based tube current modulation (TCM), and global reduction of the tube current. MATERIALS AND METHODS An anthropomorphic head phantom was scanned under six conditions: (a) without any dose reduction techniques (reference scanning);...

Conductivity and thermopower measurements of artificial three dimensional bismuth crystals are presented. Due to the size dependent band gap of bismuth, electron transport in the bismuth crystals is a combination of both metallic and hopping conduction. The conductivity and thermopower due to the hopping pathways alone can be extracted through a comparison of the properties of the artificial bi...

Stripping voltammetry as technique has proved to be very useful in the analysis of heavy and other metal ions due to its excellent detection limits and its sensitivity in the presence of different metal species or interfering ions. Recent assessments of aquatic samples have shown increased levels of platinum group metals (PGMs) in aquatic ecosystems, caused by automobile exhaust emissions and m...

We report the fabrication of thermoelectric bismuth teUuride nanowires using the template synthesis method. A simple electrodeposition procedure was used to produce the nanowires within the pores of an alumina filtration membrane. The resulting bismuth telluride/alumina composite membranes constitute an array of thermoelectric nanowires surrounded by a thermally and electrically insulating matr...

This review covers uses of bismuth catalysts since 2005 with a special emphasis on the emerging applications of such catalysts. Low toxicity, low catalytic loading, synergistic effects with other catalysts, and some hydrocompatibility properties confer to bismuth salts major advantages. The expanding activity in the field clearly highlights the growing potential of bismuth catalysts. The articl...
