The purpose of this study was to assess levels of electromyographic activity measured from rectus capitis posterior major (RCPM) muscles of asymptomatic subjects as their heads moved from a self-defined neutral position to a retracted position.
Government lawyers initially tried to prevent the Sunday field test by telling the court that the FLIR camera used on April 19 no longer existed, a position they retracted after Mr. Danforth's staff located the device in England.
The syringe plunger does not move relative to the syringe when the positioning guide is returned to the retracted position.
The syringe carrier also incorporates a constant torque spring motor, which causes the positioning guide to retract automatically and holds it in the retracted position until the operator has reinserted the cannula and is ready to begin another injection stroke.
On some grease guns, the retracted piston rod will latch into the fully retracted position, and a release tab is provided on the end of the barrel to allow the piston rod to move again.
For these two situations, the hydraulic cylinder piston rod assumes extreme stroke positions position A and position B corresponding to the fully advanced and retracted positions of the hydraulic cylinder piston rod, respectively.
Figure 8 shows the Von Mises Stress gradient determined by the analysis for: (a) spherical, (b) cylindrical and (c) tulip buoys partially submerged with radius 100 mm considering the advanced position of the hydraulic cylinder piston rod. Figure 9 is similar to Fig. 8 but concerns mainly the retracted position.
Conclusions: Movement of the scapula into a protracted or retracted position results in a statistically significant reduction in isometric shoulder elevation strength as measured in this study.
Because of "arthritis" in its robot arm, it now drives with the arm extended, to avoid the risk that it will become stuck in its retracted position.
The cooling circuits in the antenna head are designed to sustain cw W7-X plasma operation in a retracted position and 2 MW ICRH pulses with maximum 10 s duration every 300 s close to the LCFS.
In particular, the tab was designed to behave as a Gurney flap when deployed as its end prong protrudes at the airfoil trailing edge, while in retracted position the tab behaves as a trailing edge flap.
