A new method (thermal spokes) is proposed to simulate the guide rolls in FE analysis of the ring rolling process. So far this method is the only one, capable of calculating guide rolls reaction contact forces related to the stiffness of their adjustment mechanism. The method is simple to use, does not introduce further nonlinearities and could be used in any kind of FE formulations. The method ...

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 Hospita...

Abstract This study user-tested different data visualizations for highly uncertain life cycle assessments (LCAs) to determine what best supported decision-making. Precise LCAs can only be performed once designs are finalized, due the information necessary complete them, but design changes in such late stages costly. If designers could have environmental impact earlier process, sustainable choic...
