background: pancreatitis is most common complication of post-ercp and needs to admission at least for one day. the purpose of this study was to assess the efficacy of guide wire for better common bile duct (cbd) cannulation for reducing post-ercp pancreatitis. methods: from april 2010 through march 2011, the patients who needed ercp and referred to shahid beheshti and rouhani teaching hospital ...
normal 0 false false false en-us x-none ar-sa microsoftinternetexplorer4 background : distraction osteogenesis is an established option for reconstruction of amputated fingers. in contrast to the primary method of distraction osteogenesis, using kirschner wire (k-wire) as an internal fixator is not common today. this study was conducted to evaluate distraction osteogenesis with and without k-wi...
conclusions we found the magnetic field assistant device to be an accurate, radiation-independent jig for close passing of guide wire after close reduction of femoral fracture. it can reduce the need for radiation during placement of guide wire for closed intramedullary nailing of the long bones. more studies are required to improve and evaluate the technique and equipment. results outcomes of ...
This paper presents an experimental investigation into the compression behavior of shape memory alloy hybrid composites (SMAHC) subjected to quasi-static loading taking into account of rotation effects of shape memory wire in basalt continuous filament (BCF) direct roving epoxy composite. Two types of specimen prepared, the BCF direct roving reinforced epoxy composite filled with shape memory w...
Wire bonding using copper or insulated wire leads to many advantages and new challenges. Research is intensively performed worldwide, leading to many new findings and solutions. This article reviews recent advances in wire bonding using copper wire or insulated wire for advanced microelectronics packaging. Journal articles, conference articles and patents published or issued recently are review...
in this paper, based on equations of lateral vibrations of wires, a non contact method for measuring instantaneous tension in a wire is introduced. the lateral vibration of the string is measured using an eddy current transducer and is sent to a computer. this signal is then imported to suitable software for fast fourier transform (fft) processing. the first natural frequency of the string is c...
Purpose – This paper attempts to review recent advances in wire bonding using copper wire. Design/methodology/approach – Dozens of journal and conference articles published recently are reviewed. Findings – The problems/challenges such as wire open and short tail defects, poor bondability for stitch/wedge bonds, oxidation of Cu wire, strainhardening effects, and stiff wire on weak support struc...
Current experimental investigation deals with the effects of asymmetrical rolling parameters on the inhomogeneity, microstructure, mechanical, and geometrical properties of rolled brass wire. Toward this end, a roll machine with three different roll radii ratios was set up. The asymmetrical conditions are arranged using three different sets of rolls with different diameters that result into dif...
