INTRODUCTION Since anesthesia complications associated with unexpected difficult airway are potentially catastrophic, they should be avoided. The modified Mallampati test and jaw-thrust maneuver enable the identification of difficult airway. The aim of this study was to associate the modified Mallampati test and the jaw-thrust maneuver with laryngoscopy (Cormack-Lehane) in an attempt to identif...

The time-averaged thrust of an incompressible fully pulsed jet containing a period of no flow between pulses is studied experimentally as a function of pulsing duty cycle SrL and the ratio of the ejected slug length (per pulse) to the jet diameter L/D. The parameter ranges investigated were 2 <– L/D <– 6 and 0.1 <– SrL <– 0.98. Significant thrust augmentation by pulsing was observed over the en...

Fibreoptic orotracheal endoscopy under general anaesthesia may be more difficult to perform if the upper airway cannot be fully cleared. We have studied the effectiveness of jaw thrust, lingual traction and the application of both manoeuvres simultaneously, in opening up the orolaryngeal airspace in 30 ASA group 1 or 2 patients aged between 16 and 70 yr undergoing elective general surgery requi...

during the past decade, polymer nanocomposites have emerged relatively as a new and rapidly developing class of composite materials and attracted considerable investment in research and development worldwide.direct machining of polymers can be an option for personalized products and for manufacturing product samples. to obtain high quality products and reduce machining costs, it is very importa...

the noorabad-kermanshah ophiolite is part of eastern mediterranean-zagros-oman tethyan ophiolites, that this area is located in south-southwest of the main zagros thrust fault. this ophiolite consists of peridotites, serpentinites and pegmatite gabbros as mantle sequence whereas crustal sequences are composed of locally layered gabbros, isotropic gabbros, sheeted dike complex, basaltic to andes...

Consistency and trend in the Northeast and Southwest monsoon rainfall of Tamil Nadu have been studied utilizing the data for the 60-year period from 1941 to 2000. It is seen that both the Northeast and Southwest monsoon rainfall of Tamil Nadu is consistent in double mass curve analysis method. Frequency distribution of Northeast and Southwest monsoon rainfall of Tamil Nadu is normal. Decreasing...

Knowledge of the contemporary in-situ stress orientations in Earth's crust can improve our understanding active crustal deformation, geodynamic processes, and seismicity tectonically regions such as Hikurangi Subduction Margin (HSM), New Zealand. The HSM subduction interface is characterized by varying slip behavior along strike, which may be a manifestation combined variations both state mecha...

Laser ablation of a near-Earth object (NEO) on a collision course with Earth produces a cloud of ejecta that exerts a thrust on the NEO, deflecting it from its original trajectory. Ablation may be performed from afar by illuminating an Earth-targeting asteroid or comet with a stand-off “DE-STAR” system consisting of a large phased-array laser in Earth orbit. Alternatively, a much smaller stand...

Piggyback basins on the margins of growing orogens commonly serve as sensitive recorders of the onset of thrust deformation and changes in source areas. The Bieertuokuoyi piggyback basin, located in the hanging wall of the Pamir Frontal Thrust, provides an unambiguous record of the outward growth of the northeast Pamir margin in northwest China from the Miocene through the Quaternary. To recons...

Swimming effort and oxygen consumption of newly emerged green turtle Chelonia mydas hatchlings was measured simultaneously and continuously for the first 18 h of swimming after hatchlings entered the water. Oxygen consumption was tightly correlated to swimming effort during the first 12 h of swimming indicating that swimming is powered predominantly by aerobic metabolism. The patterns of swimmi...
