We test the hypothesis that the response to jaw thrust is an effective predictor of insertion conditions for the ProSeal laryngeal mask airway (ProSeal LMA). One hundred and sixty patients (ASA grade 1-3, aged >18 yr) were studied. Five anesthetists blinded to the response to jaw thrust participated in the study, each performed >30 insertions. Induction of anesthesia was with propofol titrated ...

Geodetic and seismologic studies support a tectonic model for the central Himalaya wherein ~2 cm/yr of Indo-Asian convergence is accommodated along the primary décollement under the range, the Main Himalayan thrust. A steeper midcrustal ramp in the Main Himalayan thrust is commonly invoked as driving rapid rock uplift along a range-parallel band in the Greater Himalaya. This tectonic model, dev...

In order to improve the thrust characteristics of the moving-magnet type linear permanent magnet brushless DC motor (LPMBLDCM), the structural characteristics and magnetic field are analyzed. The influence rule of electrical parameters and structural parameters on the electromagnetic properties and thrust performance are researched by finite element analysis (FEA). The effect regularity of stru...

Recent observations of an association between forearc basins and slip during subduction thrust earthquakes suggest a link between processes controlling upper plate structure and seismic coupling on the subduction-zone thrust fault. We present a mechanism for the formation of these basins where sedimentation occurs on landward-dipping segments of the subduction wedge, which itself is actively gr...

To investigate the application of a cough-creating thrust for the removal of airway-obstructing foreign material, the thrust was applied to six adult male anesthetized volunteers at the waist, at the low chest level, and at the midchest level, with the subjects in both the horizontal-lateral and the sitting positions. Air volume, peak air flow rate, and airway measurements were made. Both the l...

Wherein, the thrust fluctuation is an important factor affecting the positioning accuracy of the workpiece table. Many scholars have studied the thrust fluctuation reduction methods to improve the motor performance. Some articles optimized structure size [1], or the analytical method ignoring the end effect [2], or using look-up tables [3]. Another scholars have adopted active control strategy ...

Motivated by the requirement for pinpoint landing in futureMarsmissions, we consider the problemofminimumfuel powered terminal descent to a prescribed landing site. The first-order necessary conditions are derived and interpreted for a point-mass model with throttle and thrust angle control and for rigid-bodymodel with throttle and angular velocity control, clarifying the characteristics of the...

For the case of modeling in nonlinear ideal formulation oscillations an infinitely thin profile wing-propulsion, three components thrust force coefficient were distinguished - inertial, circulating, and vortex. The contribution to traction each obtained is investigated mechanisms wing formation at different types are explained. It revealed that inertial-circulating principle underlies work wing...

average values of< 1- t >where t is the thrust are presented for e: e: amy data and are compared with their values in hadronic interactions. as far as possible, similar analysis techniques have been employed in the two different interactions. similar variation with e is observed for this average in both data. the values of < pt> and < pl > relative to the thrust axis in e e are similar to those...

allochthonous masses are common structures in zagros fold-thrust belt. they are generally considered as collapse structures formed by the influence of gravity and in rock units with competency contrast. however, large allochthonous masses mapped in dowgonbadan area in dezful embayment near the mountain front fault (mff) of zagros show characteristics different from the belt common collapse stru...
