UNLABELLED The purpose of this study was to evaluate and compare the effect of grit blasting, chemical treatment, and application of alloy primer combinations on the shear bond strength (SBS) of a self-cure resin cement to titanium surface. MATERIALS AND METHODS Fifty cast commercially pure titanium discs (9 mm × 2 mm) were divided into five groups (n = 10), which received the following surfa...

Introduction: Although various liquid, solid, and gaseous streams of wastewater treatment plants (WWTPs) have been analyzed in many studies for the presence of SARS-CoV-2 RNA, no study was found to sample and detect SARS-CoV-2 RNA in screenings and grit samples separated from primary treatment units of WWTP. Hence, this study aims to provide an experimental protocol for sampling and extracting ...

The Gastroenterology Residents-in-Training (GRIT) course is held in conjunction with the annual Canadian Digestive Disease Week. The format of the GRIT course requires Gastroenterology trainees to submit an abstract, and if accepted, the abstract is presented. AtUBC, it is strongly recommended that trainees submit to the meeting. A questionnaire composed of 11multiple choice questions was sent ...

This study examined the effects of different treatments (polished, electropolished, and grit-blasted) on the surface morphology and chemistry of commercially pure titanium and titanium-6% aluminum-4% vanadium. The structure and composition of the surfaces were evaluated using scanning electron microscopy, atomic force microscopy, energy dispersive spectroscopy, Auger microprobe analysis, and x-...

This paper presents the effect of blade type and feeding force during resin-bonded dentin specimen preparation on microtensile bond strength (μTBS) test. Forty flat middle specimens were divided into four groups. The each group sectioned according to as follows: fine grit/20 N, grit/40 medium N obtain resin-dentin sticks with a cross-sectional area 1.0 mm2. Four from center tooth subjected μTBS...

The purpose of this study was to evaluate the generation of enamel cracks and gaps at the cavosurface margin of resin composite restorations using various burs. Saucer-shaped cavities with a bevel were prepared on mid-coronal buccal or lingual surfaces of extracted human molars using a regular-grit round diamond bur, a fine-grit diamond bur, a superfine-grit diamond bur or a six-bladed tungsten...

Research has suggested that achievement is not solely based on the cognitive abilities of the learner, but rather on the combination of cognitive ability and personality traits. This paper explores how grit affects student academic performance and success in first-year college physics students in the context of a Quebec Collège d'enseignement général et professionnel (CEGEP). Two hierarchical l...

Grit, a recently proposed personality trait associated with persistence for long-range goals, predicts achievement in a wide range of important life outcomes. Using motivational intensity theory, the present research examined the physiological underpinnings of grit during an active coping task. Forty young adults completed the Short Grit Scale and worked on a self-paced mental effort task. Effo...
