The study evaluated the influence of different luting materials on the microtensile bond strength of glass fiber posts to root canal dentin. Thirty extracted maxillary premolars were endodontically treated, and the roots were prepared for post cementation using the FRC Postec system (Vivadent). Two luting materials (Multilink, Vivadent and Clearfil Photo Core, Kuraray) were used in combination ...

In a world with numerous heterogeneous wireless technologies (e.g. WLAN, HSPA, WiMAX, Bluetooth, etc.), devices such as cell phones and laptops are more and more often equipped with multiple communication interfaces. Motivated by this trend, major wireless providers, such as Telenor [1], are looking for solutions that can fully utilize multiple technologies when present. While the term multilin...

Multiplex networks describe a large number of complex social, biological and transportation networks where a set of nodes is connected by links of different nature and connotation. Here we uncover the rich community structure of multiplex networks by associating a community to each multilink where the multilinks characterize the connections existing between any two nodes of the multiplex networ...

Objectives To compare susceptibility of five different stent platforms with longitudinal stent deformation (LSD) using a clinically relevant bench testing model simulating both short and long malapposed lengths. Background Recent data suggest that design modifications to the Promus Element stent which led to the Promus Premier stent has reduced susceptibility to LSD. However, susceptibility t...

PURPOSE To evaluate porosity volume and localization in luting cements under fixed dental prostheses after cementation using micro-computed tomography (CT). MATERIALS AND METHODS Seventy-seven sound molars were circumferentially prepared to receive all-ceramic crowns, and IPS e.max ceramic copings were fabricated according to the manufacturer's instructions. For this study, different dental l...

BACKGROUND Debonding is one of the frequent causes of failure experienced in fiber-reinforced composite posts, and establish along post space-dentin adhesive interface. The purpose of this study was to assess push-out bond strength of a fiber-reinforced post system using four different resin cements. MATERIALS AND METHODS In this in-vitro study 40 mandibular premolars were decoronated, and ro...

In this paper, a novel multilink selection framework is developed for different applications with various quality of service (QoS) requirements in avionic systems, based on the multi-attribute decision-making model. Two metaheuristic algorithms are proposed to solve model while optimizing performances. Multilink configuration and multi-homing capabilities generally required aircrafts operating ...
