The variables most affecting the ICFB performance are solids circulation flux, gas solid feedrates, riser diameter, working bed temperatures and waste properties.
Operative hysteroscopy can also be performed using small diameter, continuous flow hysteroscopes which incorporate a small, usually 5Fr or 7Fr, diameter working channel down which mechanical or electrosurgical instruments can be passed.
Electrochemical measurement was carried out with an electrochemical analyzer (VSP, Bio-logic Science Instruments, Claix, France) using a metal wire (0.12 mm in diameter) working electrode, a silver-silver chloride (Ag/AgCl) reference electrode, and a Pt counter electrode.
Electron flow, resulting from redox half-reactions occurring at specific potentials at the 100 μm Au-amalgam diameter working electrode surface, is registered as a current that is proportional to concentration [77] [79].
On the other hand voltammetric measurements were done in situ, with the sampling volume surrounding a 100 micron diameter working electrode surface being on the order of hundreds of microliters, and a full scan requiring between 3 and 5 seconds depending on instrument settings.
Therefore, our results suggest that the pupil diameter works as a measure of both hedonic valence and emotional arousal; in addition, the effects of hedonic valence and emotional arousal presumably operate on different principles (linear in valence vs. non-linear in arousal).
The imaging catheter can be inserted through an endoscope with a 3.7 mm diameter working channel, but is still too large to be introduced through the 2.8 mm working channel of most commonly used esophagogastroduodenal (EGD) endoscopes.
Fixed-diameter working channel with 20-mm diameter (METRx II) was inserted down to the zygapophyseal joint following sequentially placing dilators over each other through the incision.
The IPOM technique allows for the placement of a large mesh through a 12-mm-diameter working port to cover a hernia defect with an adequate mesh margin.
It also needs an estimate of the graph diameter to work correctly.
