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...
background: studies show that vestibular rehabilitation is an important option in the treatment bppv that is common in elderly. the purpose of this study was to analyze the effect of epley maneuver on vertigo symptoms in elderly patients with benign paroxysmal positional vertigo. methods: this cross-sectional-analytic study was performed from may 2007 to february 2010 on 67 patients (29 female,...
BACKGROUND/AIMS Degradation of adenine nucleotides to adenosine has been suggested to play a critical role in ischemic preconditioning (IPC). Thus, we questioned in patients undergoing partial hepatectomy whether (i) IPC will increase plasma purine catabolites and whether (ii) formation of purines in response to vascular clamping (Pringle maneuver) can be attenuated by prior IPC. METHODS 75 p...
This paper provides a Cramer-Rao lower bound (CRLB) on range, cross range, speed and heading tracking accuracy for a class of maneuvering target trajectories using nonlinear noisy range and bearing measurements when both the target and the sensor platform are moving. It is assumed that there are no missing or false measurements. This analysis is valid only for single target two-dimensional trac...
BACKGROUND Clearing subglottic secretions has been proved to reduce ventilator-associated pneumonia. A manual method named the rapid flow expulsion maneuver was developed to clear subglottic secretions. This study evaluates its safety and effectiveness and analyzes the influential factors. METHODS This study was composed of 2 parts. In an in vitro study, secretions were instilled directly to ...
