Body piercing indicates the puncturing of a part of the body in which jewelry may be worn. In recent years, oral piercing is increasingly popular especially among young people. Body piercing has to be considered as a surgical procedure to all intents and purposes and, as such, has to be performed only by qualified personnel able to assure high standards of professionalism in facilities subject ...

PURPOSE OF REVIEW Body art is increasing since the 1990s. Anaesthesiologists would be more and more confronted to patient with tattooing or piercing, or both. This review discusses the anaesthetic potential risks and complications observed with tattooing and piercing, their management and prevention. RECENT FINDINGS Airway management during anaesthesia is of particular interest with oral jewe...

An integrated finite element-based modeling framework is developed to predict the hole expansion ratio (HER) of AA6111-T4 sheet by considering the piercing-induced damages around the hole edge. Using damage models and parameters calibrated from previously reported tensile stretchability studies, the predicted HER correlates well with experimentally measured HER values for different hole piercin...

Unmanned aerial vehicles are being utilized by numerous groups around the world for various missions. Most of the smaller vehicles that have been developed use commercially-offthe-shelf parts, and little information about the performance characteristics of the propulsion systems is available in the archival literature. In light of this, the aim of the present research was to determine the perfo...

An experimental study was performed to design and analyze a "pusher" propeller for use by a small, expendable, autonomous unmanned aerial vehicle (UAV) whose mission was to descend from 30,000 feet to sea level at an approximately constant descent rate over a 3-hour mission duration. The entire propeller design process, from airfoil selection to final part generation in the computer-aided draft...

This paper proposes a nonlinear dynamics model for a marine propeller able to reproduce the propeller thrust over the full four-quadrant range of propeller shaft speed and vessel speed. A two-state model has been identi…ed from experimental data. The model includes a state equation for the propeller shaft speed and one that describes the dynamics of the axial ‡ow velocity. The model reproduces ...

This paper discusses a study of the effects of pylon trailing edge blowing on pusher propeller performance and noise emissions. Experimental investigations were performed in a low speed open jet wind tunnel, using a powered propeller model and a generic pylon model. A novel pylon blowing system was integrated in the aft part of the pylon to provide a uniform outflow. The numerical analysis was ...

Fluid-structure interaction between an ice sheet on the water surface and a podded R-Class propeller was examined and analyzed in terms of numerical simulation using a newly enhanced unsteady timedomain, multiple body panel method model. The numerical model was validated and verified and also checked against various previous in-house experimental measurements. The simulation was performed in a ...
