background: many types of single-use blades are manufactured with different designs and materials. there have been several reports of difficulties in obtaining a view of the glottis with single-use laryngoscopes. the purpose of this prospective study was to compare the quickness and the success rate of endotracheal intubations with two different laryngoscope blades: disposable laryngoscope blad...

A detailed review of the current state-of-art for wind turbine blade design is presented, including theoretical maximum efficiency, propulsion, practical efficiency, HAWT blade design, and blade loads. The review provides a complete picture of wind turbine blade design and shows the dominance of modern turbines almost exclusive use of horizontal axis rotors. The aerodynamic design principles fo...

A cardiac catheter enclosing an extensible blade was used to enlarge the interatrial opening in seven patients. Two patients with transposition of the great arteries who had balloon atrial septostomy as newborns subsequently presented with clinical evidence of a restrictive interatrial opening at 1 and 4 months of age. Cardiac catheterization confirmed restenosis of the interatrial opening and ...

Use of on-line fault detection techniques is integral to successful operation and maintenance of a wind turbine installation. The deployment of condition monitoring systems needs to be structured and sensitive to likely faults that may occur. In this work effects of blade faults have been simulated to understand sensitivity of blade faults on torque output. It is expected that this will help in...

BACKGROUND Plastic single-use laryngoscope blades are inexpensive and carry a lower risk of infection compared with metal reusable blades, but their efficiency during rapid sequence induction remains a matter of debate. The authors therefore compared plastic and metal blades during rapid sequence induction in a prospective randomized trial. METHODS Two hundred eighty-four adult patients under...

We aimed to evaluate whether the use of a speculum blade modifies the evaluation of pelvic organ prolapse (POP) as assessed by dynamic magnetic resonance imaging (MRI). Twenty-seven women with POP Quantification (POPQ) stage II or greater, scheduled for POP surgery, were evaluated using MRI. The procedure was repeated using the posterior blade of a standard plastic Grave's speculum to successiv...

To increase the production efficiency of a typical turbine blade, it is necessary to change its material and hence its production technology. In this respect and in order to make sure that newmat...

The ability to monitor the structural health of the rotating components, especially in the hot sections of turbine engines, is of major interest to the aero community in improving engine safety and reliability. The use of instrumentation for these applications remains very challenging. It requires sensors and techniques that are highly accurate, are able to operate in a high temperature environ...
