Shear bond strength of ceramic brackets with various base designs bonded to aluminous and fluorapatite ceramics.
This study was conducted to evaluate the shear bond strength (SBS) of various ceramic bracket base designs bonded to glazed aluminous (Vitadur Alpha) and fluorapatite (IPS e.max Ceram) ceramics, to examine the mode of failure, and to determine the debonding characteristics of the brackets and the ceramic surfaces after bond failure. Forty ceramic discs (15 mm in diameter and 1.5 mm thick) of ea...
متن کاملStomatopods
What is a stomatopod? Stomatopod crustaceans are commonly known as mantis shrimp, because their preycatching (raptorial) appendages resemble those of praying mantises. They are strictly marine and are quite distinctive from all other crustaceans, having separated from them roughly 400 million years ago and having evolved on their own unique track ever since. About 500 species are recognized tod...
متن کاملInfrared Spectroscopic Studies of Calcium Sulphate heated to High Temperatures
Infrared spectroscopic investigations have shown that on the basis of changes in the v3 , S0 4 band which occur when calcium sulphate is heated from 400° to 1400 °C, there are two forms of insoluble anhydrite, designated as ß'and /?-CaS04 . /?'-CaS04 is metastable and is completely converted into /?-CaS04 by heating above 1000 °C. With longer heating periods this conversion can even take place ...
متن کاملChanges in light-reflecting properties of signalling appendages alter mate choice behaviour in a stomatopod crustacean Haptosquilla trispinosa
Stomatopod crustaceans have complex visual systems capable of excellent spatial, colour and polarization vision. Accordingly, visual signals are used widely in their intraspecific communication behaviour. We tested the role of a particular visual signal thought to be important in mate choice in a stomatopod crustacean Haptosquilla trispinosa, by manipulating the ability of a brightly blue colou...
متن کاملFlexural strength of fluorapatite-leucite and fluorapatite porcelains exposed to erosive agents in cyclic immersion
OBJECTIVE The aim of this study was to evaluate the flexural strength of two porcelain materials (IPS d.SIGN and IPS e.max Ceram) exposed to erosive agents. MATERIAL AND METHODS One hundred and twenty bar-shaped specimens were made from each of fluorapatite-leucite porcelain (IPS d.SIGN) and fluorapatite porcelain (IPS e.max Ceram) and divided into 8 groups of 15 specimens each. Six groups we...
