OBJECTIVES Use of a rubber dam during root canal treatment is considered the standard of care because it enhances patient safety and optimises the odds of successful treatment. Nonetheless, not all dentists use a rubber dam, creating disconnect between presumed standard of care and what is actually done in clinical practice. Little is known about dentists' attitudes towards use of the rubber da...
were performed according to the guidelines of the Spanish Contact Dermatitis Research Group (abbreviated in Spanish to GEIDAC) using the standard GEIDAC series and a rubber series (Chemotechnique, Malmö, Sweden). Readings at 48 and 96 hours were positive (++) for the carba mix, the thiuram mix, the black rubber mix, tetramethylthiuram monosulfide, tetramethylthiuram disulfide, N-cyclohexylN-phe...
This paper introduces a lab project developed for the Summer Teachers’ Workshop in Genomics at Amherst College, and is easily tailored to the weekly format of undergraduate laboratory courses in genetics, genomics, molecular biology, or evolution. The project examines single nucleotide polymorphisms associated with human taste sensitivity to the bitter compound phenylthiocarbamide (PTC). Human ...
Investigation of the stationary load-deflection behaviour of tyres reveals many details of the structure and the rubber to road friction properties. These characteristics are fundamental to the understanding of the behaviour of both the stationary and the rolling tyre. In connection with racing, tyre static stiffness characteristics are of interest as they reflect on the controllability of the ...
A distinct protein specifically recognized by its strong interaction with Hevea latex lectin (HLL) was detected in the aqueous C-serum fraction of centrifuged fresh latex. This C-serum lectin binding protein (CS-HLLBP) exhibited strong inhibition of HLL-induced hemagglutination. The CS-HLLBP was purified to homogeneity by a protocol that included ammonium sulfate fractionation, size exclusion a...
Water ingress into cracked concrete structures is a serious problem, as it can cause leakage and reinforcement corrosion and thus reduce functionality and safety of the structures. In this study, the application of water-swelling rubber particles for providing the cracked concrete a self-sealing function was developed. The feasibility of applying water-swelling rubber particles and the influenc...
Alternative sleeper technologies have been developed to address the significant need for replacement of deteriorating timber railway sleepers. The review literature indicates that sleepers might fail while in service, despite passing evaluation tests current composite standards which indicated these do not represent situ on ballast. In this research, a new five-point bending test is evaluate fl...
