2) that acted to generate the rotational movement were extracted from the first force plate.
The knee and elbow are modified hinge joints that allow some rotational movement as well.
In our study, we adopted the operational definition of rolling over as a series of at least a 15[degrees] rotational movement of the trunk from one static position to another that is sustained for at least 5 min in a y-axis plane.
A single rotational slide or slump is a "more or less rotational movement, about an axis that is parallel to the slope contours, involving shear displacement (sliding) along a concavely upward-curving failure surface, which is visible or may reasonably be inferred" (Varnes, 1978).
To investigate the kinematic parameters (velocities) of the complex link 5 points using graphic- analytical method we adopt the instantaneous rotational movement of the connecting rod 5 around the VIS--point [P.sub.5] (the angular velocity [[omega].sub.5] direction is chosen arbitrarily, for example, counter-clockwise).
This rotational movement establishes a band of lower pressure that originates in Angola and migrates south until it is present over the whole coast from north to south.
The function of the ACL is to prevent the knee from forward movement of the tibia in relation to the femur and to control the rotational movement. The PCL (Posterior Cruciate Ligament) prevents the femur from sliding forwards off the tibial plateau.
It has been achieved by using completely new, specifically design movement transmission system based on three novel type piezoelectric actuators with two degrees of freedom, generating both linear and rotational movement [37, 38].
A fixed bearing permits rotational movement and prevents translation in one or more directions, while an expansion bearing permits both rotation and translations.
This device takes detailed spectra that can be displaced so that rotational movement of the galaxy can be shown.
This machine is a rock and roll rotational molding equipment enabling two main movements, the first one is the oscillation of a frame where the elements for the rotational movement are placed in; The maximum angle for oscillation movement is almost 90[degrees].
