Abstract Purpose to improve the antibacterial action of a two-step total-etch dental adhesive by using titanium dioxide-doped phosphate glass microspheres (GMs) without affecting its penetration ability. Materials and methods Five 10 wt% APTES silanized [surface treated with 3-Aminopropyltriethoxysilane (APTES)] non-silanized GMs have been used as filler Adper™ Single Bond 2 Refill. The morphol...

background: many of the problems and composite filling failures are due to dentists' inadequate and passing acquaintance with bonding principles. the aim of this study is to assess dentists' acquaintance with the bonding principles and different adhesive application that are going to be used in educational programs. methods: in this descriptive and cross-sectional study, a valid and r...

Syntactic and discourse boundaries are signalled by prosodic cues as well as linguistic cues in speech. We investigated whether there is a correspondence between prosodic or linguistic cues and the boundary strengths. We measured the rates of filled pauses (FPs) and conjunctions, and the durations of silent and filled pauses and conjunctions at four types of boundaries in casual presentations i...

Widely acknowledged as an archetypal design activity, sketching is typically carried out using little more than pen and paper. Today’s designed artifacts however, are often given qualities that are hard to capture with traditional means of sketching. While pen and paper sketching catches the character of a building, it may not equally well capture how that building changes with the seasons, how...

Young sows are subordinate and vulnerable in group-housing systems because they usually lose most fights and suffer more injuries than mature sows at mixing. This study was conducted to evaluate effects of sorting by parity on reducing aggression and associated stress with the aim to improve welfare and performance of first-parity sows in a group-housed system. Sows and gilts (n = 180) from 6 b...

"Wrong patient" insulin pen injections alarmingly frequent.

AIM To evaluate the push-out bond strength of the dentine-sealer interface with and without main cone for three resin sealers. METHODOLOGY Thirty extracted maxillary premolar teeth with two separate canals were prepared using 0.04 taper Profile instruments to size 35-45. Teeth were divided into three groups for filling using AH Plus, EndoREZ or Resilon sealers. In each tooth, one canal was fi...

A high-sensitivity fiber-optic gas pressure sensor based on a Fabry-Perot interferometer filled with epoxy resin adhesive is proposed. The factors of affecting the sensitivity are theoretically analyzed and verified experimentally. In our experiment, epoxy-filled thinnest diaphragm thickness <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink...
