The purpose of this study was to examine the effect of opaque on resin bonding to calcium phosphate crystalline ceramics (CPCC). Disk-shaped specimens were made from the calcium phosphate crystalline ceramics (Crys-Cera). All specimens were ground with 800-grit abrasive paper, cleaned and finally air-dried. Control group (CT group) didn't undergo any treatment. Coating of one layer opaque treat...

Dense wavelength division multiplexing (DWDM) opaque networks use expensive optical/electrical/optical (O/E/O) conversion at each end of a fiber link. Several technological advances have been used in an attempt to reduce the O/E/O conversion cost component: improved optical amplifiers using distributed Raman amplification allow signals to traverse longer distances without amplification and/or r...

This paper addresses the problem of reconstructing nonoverlapping transparent and opaque surfaces from multiple view images. The reconstruction is attained through progressive refinement of an initial 3D shape by minimizing the error between the images of the object and the initial 3D shape. The challenge is to simultaneously reconstruct both the transparent and opaque surfaces given only a lim...

The purpose of this study was to evaluate the effects of acidic primers on adhesive bonding to sintered aluminum oxide (alumina). Alumina disks were primed with one of the following materials: Acryl Bond, All Bond 2 Primer B, Alloy Primer, Estenia Opaque Primer, Eye Sight Opaque Primer, M.L. Primer, MR. Bond, and Super-Bond Liquid. Specimens were then bonded with an acrylic resin initiated with...

We present a real-time technique for rendering translucent features on opaque volumetric surfaces. It relies on modern reprogrammable graphics hardware to compute the complicated visual phenomena seen in translucent materials. The proposed technique is based on relief mapping techniques, and is therefore capable of interacting with the underlying opaque surface accurately. A hard self-shadowing...

In Candida albicans the transcription factor Efg1, which is differentially expressed in the white phase of the white-opaque transition, is essential for expression of the white phenotype. It is one of six transcription factors included in a proposed interactive transcription network regulating white-opaque switching and maintenance of the alternative phenotypes. Ten sites were identified in the...

Opaque predicates are a commonly used technique in program obfuscation, intended to add complexity to control flow and to insert dummy code or watermarks. We survey a number of methods to remove opaque predicates from obfuscated programs, hence defeating the intentions of the obfuscator. Our main contribution is an obfuscation technique that introduces opaque constant predicates that are provab...
