Strain and Force Measurement in Wire Guide

Weak Force Measurement in Bistable Optomechanical System

One of the main milestones in the study of opto-mechanical system is to increase the sensitivity of weak forces measurement up to the standard quantum limit. We have studied the detection of weak force under a bistable condition in red detuned regime. In this case, dynamics of the system behaves asymptotically similar to stationary state and applying external force affects phase and fluctuation...

[Lost guide wire - lessons learned].

Central venous catheter placement is a relatively common procedure in current practice, but it is not devoid of risks. Utmost care must be taken to follow a correct technique, and only appropriately trained and/or supervised medical professionals should perform this invasive act. One of the possible complications, completely avoidable by appropriate care, is the intravascular loss of the guide ...

Static Strain Aging Behavior of Low Carbon Steel Drawn Wire

The static strain aging is a phenomenon that can change the mechanical properties of low carbon steels. Thus, the static strain aging behavior of low carbon steel wires after drawing process is studied. To do so, the wires are austenitized at different temperatures and cooled in different rates. Then the wires are drawn and aged at a specific temperature and time. Before and after aging of each...

Evaluation of guide wire cannulation in reduced risk of post - ERCP pancreatitis and facilitated bile duct cannulation

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...
