Color agreement between nanofluorapatite ceramic discs associated with try-in pastes and with resin cements.
The aim of this study was to evaluate the in vitro color agreement between nanofluorapatite ceramic discs (e.max Ceram / Ivoclar Vivadent / A2) associated with try-in pastes and those bonded with resin cements (Vitique / DMG/ try-in shade A2½ and cement shade A2½, Variolink II / Ivoclar Vivadent / try-in shade A1 and cement shade A1, and Choice 2 / Bisco / try-in shade A2 and cement shade A2), ...
متن کاملThin Discs, Thick Discs and Transition Zones
Accretion onto a compact object must occur through a disc when the material has some initial angular momentum. Thin discs and the thicker low radiative efficiency accretion flows (LRAFs) are solutions to this problem that have been widely studied and applied. This is an introduction to these accretion flows within the context of X-ray binaries and cataclysmic variables. Accretion describes the ...
متن کاملEffect of different light curing methods on mechanical and physical properties of resin-cements polymerized through ceramic discs
OBJECTIVE The aim of this study was to compare the polimerization ability of three different light-curing units (quartz tungsten halogen, light-emitting diodes and plasma arc) and their exposure modes (high-intensity and soft-start) by determination of microhardness, water sorption and solubility, and diametral tensile strength of 5 dual-curing resin cements. MATERIAL AND METHODS A total of 7...
متن کاملBonding and structure of ceramic-ceramic interfaces.
Quantum molecular dynamics simulations of α-Al2O3(0001)/3C-SiC(111) interfaces reveal profound effects of thermal annealing for producing strong interfaces consisting solely of cation-anion bonds and their consequence on interfacial structures. A Si-terminated SiC surface and Al2O3 form a stronger interface (Si-interface) with a Si-O bond density of 12.2 nm(-2), whereas the C interface has an ...

and clatter. The Italians call them buffone — clowns. The large white grubs feed on roots and can be a major pest of grass and potatoes. Now controlled by pesticides, they were once far more abundant locally. In 1574, adult cockchafers were so numerous in the Severn Valley that their drowned bodies blocked the wheels of watermills, the book describes. In parts of Europe, if not in Britain, the ...
