Dear Sir, it was a pleasure reading the article “Transoral endoscopic adenoidectomy” by A. El-Badrawy andM. AbdelAziz published in Volume 2009 (2009) of this journal (Article ID 949315). Adenoidectomy has been an old surgery and has been done with various techniques [1]. The technique described in this article is definitely better than conventional technique of adenoidectomy. However, I feel th...

Physical conditioning, technical ability, contact, and protective equipment have been identified through research as factors that can potentially contribute to the incidence of injuries in ice hockey players. One safety-related factor often overlooked is the interaction between the skate blade and the ice. Skating is one of the fundamental skills of a successful hockey player, but the effect of...

conclusion high-resolution mr images of the wrist using 3d t2space, pd blade and t2 blade were superior to those using conventional sequences quantitatively. high-snr and cnr mr imaging with space and blade would be a promising method to diagnose wrist lesions. results snr of the cartilage, tfcc on 3d t2space and t1 fse was better than other sequences (p < 0.001). snr of the bone on pd blade wa...

The Axial compressor is an integrated part of a gas turbine. The central part of compressors is its blades. Blade aerodynamic has a significant effect on compressor performance. Because of the adverse pressure gradient in the compressor, any deviation in the blade profile has a significant influence on the flow field as well as the compressor performance. During the manufacturing and operation ...

In the Virtual Computing Laboratory (VCL) users request a computing resource (e.g., a blade) and customized software (an “image”). The software is loaded onto the blade from an image server. If loading is performed at the time of the request, the user experiences a delay before s/he can access the blade. This delay may be several minutes long, depending on the type of image requested. A “preloa...

A finite-volume implicit, unsteady, multiblock, multigrid, upwind solver, and structured multiblock grid generator for rotors are presented, and applied to lifting rotors in forward flight. These flows are particularly expensive to compute as the accurate capture of the detailed vortical wake requires fine meshes away from the blades and, hence, a parallel version of the code has been developed...

A numerical study of the dynamic behaviour of a turbine meter measuring solid flowrate was carried out by use of the discrete element method. The simulation was conducted with a cylindrical standpipe of 30d in diameter and 40d high, filled with 30000 mono-sized spheres of diameter d, and with a turbine fixed at the centre of the standpipe at a height of 20d. The variations of the torque and rot...

As previously discussed, because of differences in anatomy, there are differences in techniques for intubating the trachea of infants and children compared with adults.[1–4,17–19,99,114,115] Because of the smaller dimensions of the pediatric airway there is increased risk of obstruction with trauma to the airway structures. A technique to be avoided is that in which the blade is advanced into t...

Purpose: To investigate whether helical blade implant systems have advantages in terms of tip apex distance (TAD) and cut-out rate in comparison to conventional lag screws for intertrochanteric fractures in a geriatric population. Methods: Relevant articles were sourced from the MEDLINE, Embase, Ovid and Cochrane Library databases from inception through March 2015. All randomized controlled tri...
