This study was designed to detect the sensitivity of different methods of eliciting knee jerks and to compare the conventional methods with the newly purposed maneuver. Knee jerk (a deep tendon reflex) was elicited in 123 apparently normal population (77 males and 46 females) with three different methods (1) without applying reinforcement, (2) applying Jendrassik maneuver (strong voluntary cont...

Applying manual uterine fundal pressure is a maneuver performed to shorten the second stage of labor. This maneuver involves the application of manual pressure to the uppermost part of the uterus (uterine fundus) and directed towards the uterine axis. How often this maneuver is performed in routine obstetric practice is unclear; however, it is much more frequently performed in developing than d...

Maneuver Regulation, Transverse Feedback Linearization and Zero Dynamics Christopher Nielsen Masters of Applied Science Graduate Department of Electrical and Computer Engineering University of Toronto 2004 The maneuver regulation (or path following) problem has received considerable attention in the control literature where feedback linearization has proven an effective approach to solving the ...

In this paper, slewing maneuver of a flexible spacecraft with large angle of rotation is considered and assuming structural frequency uncertainties a robust minimum-time optimal control law is developed. Considering typical bang-bang control commands with multiple symmetrical switches, a parameter optimization procedure is introduced to find the control forces/torques. The constrained minimizat...

PURPOSE The aim of our study was to assess the hemodynamic change of liver during the Valsalva maneuver using Doppler ultrasonography. METHODS Thirty healthy men volunteers were enrolled (mean age, 25.5±3.64 years). The diameter, minimal and maximal velocities, and volume flow of intrahepatic inferior vena cava (IVC), middle hepatic vein (MHV), and right main portal vein (RMPV) was measured d...

Although there have been a variety of studies about vehicular maneuvers on land or sea, maneuvers within a small area that require direction changes have rarely been discussed. The arrival or departure of ships to or from ports requires safe and effective turning maneuvers within a narrow area. In this study, we decompose the maneuver procedure into several operations, then establish an operati...

The use of nasopharyngoscopy during the application of intrathoracic pressure (Müller maneuver) is frequently employed to establish the site of upper airway obstruction. The Müller maneuver, however, is used when the patient is awake and therefore may not correlate with obstruction occurring during sleep. Aim: to compare the degree of pharyngeal obstruction in the retropalatal and retroglossal ...

Abnormal responses to a standardized Valsalva maneuver have been proposed as additional Criteria for heart failure. The present study was undertaken to determine the variability of these responses in normal subjects as well as frequency of abnormal responses in cardiac patients. Only phase II responses could be considered reliable for this purpose. Discrepancies between phase II responses were ...
