We sought to evaluate immediate and delayed micro-tensile bond strength of Panavia F2.0 and Multilink Sprint resin cement to superficial, deep and cervical dentin. Thirty-six freshly extracted non-carious human molars were sectioned in the mesiodistal direction to expose three different dentin regions including superficial dentin (1 mm below the dentine-enamel junction), deep dentin (1 mm above...

Objective. The aim of this study was to evaluate the radiopacity of two conventional cements (Zinc Cement and Ketac Cem Easymix), one resin-modified glass ionomer cement (RelyX Luting 2) and six resin cements (Multilink, Bistite II DC, RelyX ARC, Fill Magic Dual Cement, Enforce and Panavia F) by digitization of images. Methods. Five disc-shaped specimens (10 × 1.0 mm) were made for each materia...

Earth-moving machines such as hydraulic excavators are usually used for carrying out contact tasks. Impedance control can be employed as an approach for achieving compliant motion in such tasks. This paper describes a position-based impedance controller that has been developed in our laboratory for excavator-type manipulators, and presents supporting experimental results. First, the problem of ...

We present two patients with a displaced fracture of the small finger metacarpal base, where the shaft of the small finger metacarpal was wedged between the bases of the ring and small finger metacarpals. The striking appearance on radiographs led to initial recommendations for surgery, but both patients preferred non-operative treatment and did well in the short term without surgery

finger prints of 68 patients with down's syndrome and 93 controls have been collected and analyzed for topological of formulation of finger tip patterns suggested by loesch (1975). the results showed that there may be great differences in the dictionary of the finger patterns of the patients and their controls. mean lunar and radial patterns showed mostly significant differences among the patie...

The purpose of the TRENDS trial was to assess the safety, efficacy, and cost effectiveness of a no-predilatation ("direct") stenting strategy in the treatment of de novo native coronary artery lesions using the Multilink Tetra stent system. In this multicenter, prospective clinical trial, 1,000 patients were randomized (1:1) to receive a Multilink Tetra stent with or without balloon predilatati...

abstract  background: the goal of this report is to show our results with extension block technique for treatment of mallet fracture. the indications for this technique were the presence of a large bone fragment, and palmar subluxation.  methods: we retrospectively assessed the results of treatment in 14 mallet fractures  which have been treated by extension block technique to determine the ran...

This article presents a novel and cost-effective vector network analyzer (VNA)-based phase-compensated channel sounder operating in the frequency range of 10–50 GHz using radio-over-fiber (RoF) techniques, which can support multilink/channel long-range phase-coherent measurements. The optical cable enables measurements with dynamic 115.7 dB at 30 (for back-to-back connection). phase compensatio...

osteoid osteomata are rarely found in the distal phalanges of the hand. the usual presenting features are chronic pain, nail enlargement and increase in size of the terminal part of the digit. diagnosis is difficult but surgical excision is effective for treating the patients’pain. we reported this tumor in distal phalanx of the middle finger.
