• Pre-cementation procedures can affect both cement retention and crown strength. Zirconia materials with different amounts of yttria-stabilizer benefit from pre-cementation procedures. Disc-shaped specimens are not suitable to assess all aspects pre-treatment for prosthetic restorations. Several have been advocated enhance adhesion between zirconia resin-based cement. There is, however, limite...

The further development of Fe(0)-based remediation technology depends on the profound understanding of the mechanisms involved in the process of aqueous contaminant removal. The view that adsorption and co-precipitation are the fundamental contaminant removal mechanisms is currently facing a harsh scepticism. Results from electrochemical cementation are used to bring new insights in the process...

This research was performed to determine the efficiency effect of sedimentary environment of Kerman City area on soil structure bycomparing natural and reconstituted consolidation curves. In this regard, four different criteria such as sensitivity strength, stresssensitivity, Schmertman criteria and the result of the uniaxial compression test were used. The base of these criteria is to compare ...

This article describes CAD/CAM technology used in dentistry and different restorative materials used in conjunction with adhesive cementation with particular attention given to the evolution of the CEREC system, as well as various ceramics developed for this system. Advantages and limitations of materials and technique are also discussed.

Research has been conducted into the diagenesis of the Luxembourg Sandstone. Literature studies were followed by a visit to the outcrop, after which thin sections were studied. The Luxembourg Sandstone Formation has been deposited in the Hettangian and Sinemurian, both lower Jurassic ages. A sea strait connecting the Northern German Basin and the Paris Basin was located in present day Luxembour...

BACKGROUND Metastatic disease to the shoulder girdle is a challenging problem because of the potential for pain, pathologic fracture and loss of function of that limb. Management of the bone disease centers around palliation, prevention of further complications and the preservation of residual function. A variety of surgical options exist for managing metastatic disease to the shoulder girdle a...

UNLABELLED During post preparation, the root canal is exposed to the oral cavity, and endodontic treatment may fail because of coronal leakage, bacterial infection and sealing inability of the luting cement. OBJECTIVE this study quantified the interfacial continuity produced with conventional dual-cure and self-adhesive resin cements in the cervical (C), medium (M) and apical (A) thirds of th...

The influence of two different fluoride-based activator salts (NH4F and AlF3) was studied for diffusion aluminide coatings obtained via pack cementation on a Ni-based superalloy (René 108DS). resistance to oxidation hot corrosion assessed as function the concentration used during synthesis process by means cementation. Two concentrations were selected (respecting equimolarity fluoride in synthe...
