The transmittance minima of 18 absorption bands of a solution of 40 g/L holmium oxide in 10% ͑volume fraction͒ perchloric acid are certified as intrinsic traceable wavelength standards, by means of a multicenter measurement on material from a single source coupled with comparisons of a variety of preparations of the material evaluated on a single(More)
PURPOSE The aim of this study was to clinically assess the impact of a prefabricated implant-retained stent clipped over healing abutments on the preservation of keratinized mucosa around implants after implant surgery, and to compare it with horizontal external mattress sutures. METHODS A total of 50 patients were enrolled in this study. In the test(More)

Context-awareness is one of the most important technologies for the ubiquitous computing. To embed such a technology into applications, first of all, a well-defined architectural framework is required to support applications to obtain necessary contexts. Several studies have been proposed, but most of them overlooked one fundamental feature that contexts(More)
