The purpose of this evidence-based project was to determine the perceptions of anesthesia providers regarding the use of disposable laryngoscope blades. Frequency of use, ease of use, and complications encountered when using the disposable blade were evaluated before and after an in-service program designed to increase the use of disposable blades. Participants completed an anonymous questionna...

Cattail or Typha, an emergent aquatic macrophyte widely distributed in lakes and other shallow water areas, has slender blades with a chiral morphology. The wind-resilient Typha blades can produce distinct hydraulic resistance for ecosystem functions. However, their stem may rupture and dislodge in excessive wind drag. In this paper, we combine fluid dynamics simulations and experimental measur...

large-scaled blade has posed many problems related to design and production. After introducing the features of blade with thick airfoils and flatback, based on relevant parameters of Huaren 100 kW wind turbine, the paper designed blade with thick airfoils and flatback, introduced blade parameter design, and analyzed the aerodynamic performance of blades using GH bladed software, obtaining the r...

Design and development of large blades is very challenging due to economics, logistics, and technical barriers. Regarding the technical barriers, designs must satisfy deflection, buckling, fatigue, and stability requirements. This is a very challenging design problem, and one that becomes more challenging to do costeffectively as blades grow even longer. Sandia National Laboratories has been re...

Two different inverse design approaches are proposed for developing wind turbine blades for sub-scale wake testing. In the first approach, dimensionless circulation is matched for full scale and sub-scale wind turbine blades for equal shed vorticity in the wake. In the second approach, the normalized normal and tangential force distributions are matched for large scale and small scale wind turb...

the need to establish power plants to supply the required electricity of the country has been rising due to increasing demand levels as well as the lack of governmental resources. furthermore, the available traditional attitude in performing and conducting power plant projects has made government seek a modern attitude. this paper tries to use the topics that have been employed in automotive in...
