The purpose of this investigation was to study, in vitro, the antifungal effect of mineral trioxide aggregate (MTA) using a tube-dilution test. MTA was tested freshly mixed and after 24 h set on Candida albicans. The tested MTA was incubated with C. albicans for 1 h, 24 h, and 3 days. Results showed that the freshly mixed MTA was effective in killing the tested fungi after 1 day of contact, whe...

The Dirac reduction technique used previously to obtain solutions of the classical dynamical Yang-Baxter equation on the dual of a Lie algebra is extended to the PoissonLie case and is shown to yield naturally certain dynamical r-matrices on the duals of Poisson-Lie groups found by Etingof, Enriquez and Marshall in math.QA/0403283.

Mixtures of mineral aggregate and modified sulfur, wherein the modified sulfur functions as a binder, are termed sulfur concretes or sulfur mortars depending on the form of the mineral aggregate. Molten sulfur reacted with olefinic additive, at 130-140 ºC, and then mixed with preheated filler and aggregates. Sulfur mortar samples were prepared by mixing 32 % molten sulfur, 10 % filler and 5...

The influence of three material factors, namely asphalt-aggregate ratio, fiber-aggregate ratio and mineral filler–aggregate ratio (filler–aggregate ratio) on Marshall indexes of the lignin fiber SMA mixture are investigated in this study. To achieve this goal, orthogonal experiment design and implementation of Marshall stability test, residential stability test and rutting test were used to ana...
