Ti6Al4V alloy forms an oxide layer on the Surface and is metallic material used as a biomaterial. The investigation determined level lof wear of corrosion fabricated by additive manufacturing in titanium specimen made forge subjected to anodizing. use NaOH (0.1M) H2SO4 (1M) was defined electrolytes, with time 5 minutes, voltage 20 40V, tests Pin Disk resistance Hank solution. Evidencing usefuln...

abstract background: distal radial fracture is one of the most common fractures of the skeletal system. although it has been believed to be a simple fracture with excellent outcomes, practical operations’ results have always been undesirable and even poor. the goal of this study was to compare two methods of treatment “pin and plaster and precautious pin fixation in patients with unstable extra...

We analyze the eigenvalues and eigenvectors of the staggered Dirac operator in quenched lattice QCD in the vicinity of the deconfinement phase transition using the Lüscher-Weisz gauge action. The spectral and localization properties of the low-lying eigenmodes show characteristic differences between the Z3 sectors above the critical temperature Tc. These findings can be interpreted in terms of ...

Introduction: The restoration material commonly used as core material for pulpless posterior teeth is mostly amalgam due to its high strength and low cost and it can be used with or without pin. The aim of this study was to evaluate the influence of post material on stress distribution in mandibular second premolar tooth by finite element analysis. Method: The stress distribution was analyzed i...

I n this paper, trading symbols of the 30 largest companies listed in the Tehran Stock Exchange (TSE) were ranked based on the asymmetry information risk. Using the Ersan and Alici (2016) modified clustering algorithm (EA), we estimated the probability of informed trading (PIN) to measure the asymmetry information among traders for each trading symbol and trading day through two-year...

Interactive video-on-demand applications pose a number of interesting problems such as the support of fast forward and rewind at arbitrary speeds. While it has been shown that no single data layout scheme can support these functions at arbitrary speeds without violating load balance conditions, researchers are now exploring methods to allow at least a wide range of speeds to be supported under ...

The use of aluminum alloys as a material for engineering components that rub against each other is increasing, so it important to know the friction characteristics these alloys. In this study, Aluminum 2024 was given heat treatment with variation in aging time and anodization. Then, wear coefficient tests were carried out using pin tool on disc. effect surface anodization are determine amount t...

Abstract The direct blending of polyether ether ketone (PEEK) with a solid lubricant such as polytetrafluoroethylene (PTFE) improves its tribological performance, but compromises outstanding mechanical properties and processability. While these negative effects might be circumvented via the hybrid wear method, influence contact temperature between multiple sliding components acting together is ...
