this paper addresses an experimental investigation in the hydrodynamic behavior of a modified slotted sieve tray. slotted sieve tray (push valve sieve tray) is a sieve tray that the push valves have been utilized on the tray deck to eliminate liquid gradients and non-uniformity of liquid distribution on the tray. the air-water system was used in an industrial scale experimental rig with an inte...

conclusions this study suggested that chlorhexidine had no negative effect on the bond strengths of mta-treated dentin. results there were no statistically significant differences between all the experimental groups. the mode of bond failure was predominantly mixed for distilled water groups and cohesive for chx groups. materials and methods sixty dentin disks with a thickness of 1.5 ± 0.2 mm a...

In this rebuttal, I will provide an empirically supported deconstruction of Dan’s primary lines of reasoning, in order to assess the validity of his underlying assumptions. My goal in presenting this counter-perspective is not to push back against Dan (in fact, I appreciate the discussion he has stimulated as a “devil’s advocate”), but rather to give fellow advisors a framework for assessing th...
