phenolic resin is among the oldest thermoset resins that have found wide spread applications in several industries, largely due to its high thermal resistance. in this research, room temperature curing of phenolic resin and its reinforced silica composite has been investigated by p-toluene sulphonic acid as a catalyst. mechanical properties of the composites such as impact strength, flexural pr...

A Hindu lady, aged 32 years, came with a boil on her left breast, about 3 inches below the clavicle fur treatment on 31st July 1913. It was found when examined, quite mature and tit for opening. But operation was obstinately refused. Needling by the la<ly, however, brought the pus out; but there was considerable pain, swelling and redness about the region, giving indication of bagging. The exte...

INTRODUCTION It is unknown how the use of a light-cured acrylic resin is appreciated over the traditional chemically cured resins for the construction of custom trays in a teaching environment. OBJECTIVE To evaluate the acceptance of light-cured acrylic resin for custom trays by dental students. METHOD A questionnaire addressing the use and handling properties of both light-cured (Megatray,...

AIM To evaluate the influence of post design and roughness and cement system (dual- or self-cured) on the retention of glass fibre posts. METHODOLOGY Two tapered and smooth posts (Exacto Cônico No. 2 and White Post No. 1) and two parallel-sided and serrated posts (Fibrekor 1.25 mm and Reforpost No. 2) were adhesively luted with two different resin cements--a dual-cured (Rely-X ARC) and a self...

The present study demonstrates the impact of specific breed on the characteristics of dry-cured ham. Eighty thighs from Korean native pig (KNP), crossbreed (Landrace×Yorkshire)♀×Duroc♂ (LYD), Berkshire (Ber), and Duroc (Du) pig breeds (n = 10 for each breed) were used for processing of dry-cured ham. The thighs were salted with 6% NaCl (w/w) and 100 ppm NaNO2, and total processing time was 413 ...

BACKGROUND Economic evaluations often measure an intervention effect with mean overall survival (OS). Emerging types of cancer treatments offer the possibility of being "cured" in that patients can become long-term survivors whose risk of death is the same as that of a disease-free person. Describing cured and noncured patients with one shared mean value may provide a biased assessment of a the...
