An attitude control strategy for maneuvers of an interconnection of planar bodies in space is developed. It is assumed that there are no exogeneous torques and that torques generated by joint motors are uscd as means of control so that the total angular momentum of the multibody system is a constant, assumed to be zero in this paper. The control strategy utilizes the nonintegrability of the exp...

This paper studies a flight load test method for helicopter blade, including the structural force of strain gauge bridge modification, calibration and establishment equation in typical maneuvers. First, blade structure was analyzed gauges were pasted profile which considered to be important positions analysis safe helicopter. Second, Load equations obtained by ground test, would used convert ti...

Mechanical ventilation can cause and perpetuate lung injury if alveolar overdistension, cyclic collapse, and reopening of alveolar units occur. The use of low tidal volume and limited airway pressure has improved survival in patients with acute lung injury or acute respiratory distress syndrome. The use of recruitment maneuvers has been proposed as an adjunct to mechanical ventilation to re-exp...

When placed on a temperature gradient, a Drosophila larva navigates away from excessive cold or heat by regulating the size, frequency, and direction of reorientation maneuvers between successive periods of forward movement. Forward movement is driven by peristalsis waves that travel from tail to head. During each reorientation maneuver, the larva pauses and sweeps its head from side to side un...

INTRODUCTION Non-contact anterior cruciate ligament (ACL) injuries are devastating knee injuries experienced by athletes who participate in sports that involve jump landings and cutting maneuvers and are 2-8 times more prevalent in females compared to males. This injury generally occurs approximately 40 milliseconds after initial ground contact while the athlete performs an abrupt, split-second...

Free-flying male praying mantises Parasphendale agrionina (Gerst.) perform evasive maneuvers when stimulated by ultrasound and when attacked by hunting, echolocating bats. They do not, however, respond in any way when standing on a substratum. The maneuvers are graded in intensity with distance from the sound source: far from the source they are simple turns, whereas close to the source they ar...

[Purpose] To investigate the effects of a pelvic compression belt (PCB) and chair height on the kinematics and kinetics of the lower extremity during sit-to-stand (STS) maneuvers in healthy people. [Subjects and Methods] Twenty-two people participated in this study. They were required to perform STS maneuvers under four conditions. Hip joint moment and angular displacement of the hip, knee, and...

Safety maneuvers are defined as strategies people use to manage or avoid their perceived threats. The present study presents the development of the Texas Safety Maneuver Scale (TSMS), an instrument that assesses the pattern and extent of use of safety maneuvers in formerly treated panic patients. Ex-patients (Nˆ 105), who had completed cognitive behavioral treatment at the Anxiety Disorders Lab...

OBJECTIVE Respiratory complications are the main causes of morbidity and mortality in patients with neuromuscular disease (NMD). The objectives of this study were to determine the effects that routine daily home air-stacking maneuvers have on pulmonary function in patients with spinal muscular atrophy (SMA) and in patients with congenital muscular dystrophy (CMD), as well as to identify associa...
