BACKGROUND Supraglottic airway devices (SGA) are commonly used in pediatric anesthesia and serve as primary or back-up devices for difficult airway management. Most SGA are marketed without proper clinical evaluation. The purpose of this study was to evaluate the performance of the pediatric LMA Supreme™, Air-Q® and Ambu® Aura-i™. METHODS This prospective observational study was performed at ...

logistics outsourcing has been at the top of the management agenda during recent decades. the selection of the proper service supplier is the key to success in logistic outsourcing firms could select the right supplier by applying appropriate methods and selection criteria. in this paper a new framework is proposed on the basis of weighted additive fuzzy programming approach and linear programm...

planners have regarded understanding urban use per capita since the beginning of new thinking of urban development. this was stared with its pragmatics toward primary comprehensive urban plans and became a source for urban development plans that have tried to adapt per capita and standards with country’s conditions. iran's supreme council for planning and architecture, determined standards...

This paper provides a non-symmetric generalization of the position value for communication situations. The definition of the weighted position value is motivated by the two different kinds of asymmetry in communication situations. It is shown that the weighted position value is characterized by component efficiency and a modification of balanced link contributions that is used by Slikker (Inter...

This paper is considering the problem of dividing fairly the worth of the grand coalition in a transferable utilities game, in case that the coalition is formed. The computational experience for the Shapley Value, the most famous solution, is extensive, but the case of the Weighted Shapley Value and that of the Kalai-Samet Value have been barely considered. Based upon some results connected to ...

the purpose of this study was to evaluate the shear bond strength (sbs) of orthodontic brackets bonded with two types of nano-composites in comparison to a conventional orthodontic composite.sixty extracted human first premolars were randomly divided into 3 groups each containing 20 teeth. in group i, a conventional orthodontic composite (transbond xt) was used to bond the brackets, while two n...

BACKGROUND AND OBJECTIVE The Supreme laryngeal mask airway (LMA) is a new single-use polyvinyl chloride supraglottic device that combines the functionality of the ProSeal and Fastrach airways. High oropharyngeal leak pressures are important as they indicate airway protection, feasibility of positive pressure ventilation and likelihood of successful LMA placement. The oropharyngeal leak pressure...

rhabdomyosarcoma is a common primary childhood malignancy that rarely metastasizes to the breast. we report a patient with a primary sinonasal rhabdomyosarcoma metastasizing to the breast, with no distant spread. we describe the imaging appearance of rhabdomyosarcoma on magnetic resonance imaging (mri), particularly on diffusion-weighted imaging (dwi) and apparent diffusion coefficient (adc) se...
