Suggestion of a standard maneuver in cap-assisted colonoscopy: hooking and dragging maneuver

Cap-assisted colonoscopy versus standard colonoscopy: is the cap beneficial? A meta-analysis of randomized controlled trials

Background In an effort to improve visualization during colonoscopy, a transparent plastic cap or hood may be placed on the end of the colonoscope. Cap-assisted colonoscopy (CAC) has been studied and is thought to improve polyp detection. Numerous studies have been conducted comparing pertinent clinical outcomes between CAC and standard colonoscopy (SC) with inconsistent results. Methods Nume...

Modified Valsalva Maneuver vs. Standard Valsalva Maneuver on Emergency Department Patients Presenting with Supraventricular Tachycardia

Background: Supraventricular tachycardia (SVT) is a relatively common dysrhythmia among the general population and a common dysrhythmia presenting to the emergency department. Generally speaking, it is assumed the provider should attempt a vagal maneuver as first-line treatment for SVT, and the most common vagal maneuver used is the Valsalva. Current resources describing the method to perform t...

Wave Effects on Free Running Ship in Standard Zigzag Maneuver

Numerical simulation of hull and propeller interaction in acceleration maneuver

Prediction of a ship’s trajectory during a maneuvering motion is so important. In this study, the acceleration maneuver for a twin-screw vessel is directly investigated using computational fluid dynamic (CFD) environment and unsteady RANS (Reynolds Averaged Navier-Stokes) solver. For this purpose, the self-propulsion and acceleration simulations with hull and propeller interaction for the well-...

Analysis of Stresses in Helicopter Composite blade in Hovering Maneuver

The main purpose of this article is the structural analysis of a composite blade of a selected helicopter. In this study, the stresses on rotors' blades caused by centrifugal forces, lift, drag and torque are analyzed. The governing equations of the structure behavior and solving processes were carried out by MATLAB software, and simulation is carried out by ABAQUS software, and they are compar...
