rotation

 [ro-ta´shun]
1. the process of turning around an axis.
2. in obstetrics, the turning of the fetal head (or presenting part) for proper orientation to the pelvic axis. It should occur naturally, but if it does not it must be accomplished manually or instrumentally by the obstetrician or manually by the nurse-midwife.
3. a clinical assignment for students in a specific clinical area.
4. in dentistry, the turning of a malturned tooth into its proper position.
pelvic rotation movement of the pelvis around an imaginary axis.
site rotation the selection of sequential injection locations for a patient receiving multiple injections. A chart is frequently utilized to guide the nurse in rotating sites so that the same location is not used repeatedly, which would lead to tissue damage and irregular absorption of drugs.

ro·ta·tion

(rō-tā'shŭn),
1. Turning or movement of a body around its axis.
2. A recurrence in regular order of certain events, such as the symptoms of a periodic disease.
3. In medical education, a period of time on a particular service or specialty.

rotation

Movement around an axis Graduate education A period of time during which a medical student, or a physician in an early period of his training works in a particular service. See Audition rotation, Clinical rotation, Extern, Intern Obstetrics The turning of a fetus around its long axis such that the presenting part changes. See External rotation, Internal rotation, Limb rotation.

For torque, the arm of movement was calculated dynamically between starting point of interaction and point of rotation. If the distance between interaction point and point of rotation is greater, rotation by a larger angle is produced.
The periodic changes in [w.sub.TD] show that the interfaces between the blue and green bands in Figure 4(b) are small-angle tilt boundaries causing clockwise and anticlockwise rotations around TD.
Using three replicates, with tillage treatments in main plots and crop rotations in sub-plots, a split-plot randomized complete block design was used in present study.
Despite improvements in flexion, abduction, and external rotation, the treatment results for internal rotation, such as HBB, and internal rotation in flexion and abduction were unacceptable to him due to occupational demands.
Focusing on our institutional experience transitioning from an optional to mandatory urology rotation, we demonstrated that students who rotated through urology lead to a perceived improvement in knowledge, skill sets and confidence in managing common urological conditions.
The only differences were less blood loss and a lower risk of significant hemorrhage (>1.5 L) in the rotation group (odds ratio, 0.24; 95% confidence interval, 0.13-0.64).

An absolute solution to such related health scheduling challenges is offered by Rotation Manager.
At Beresford, the experiment was started in 1991 (24 years) to study the effects of tillage management and crop rotations on crop production and soil properties.
However, over the long-term, the diverse rotation in which the frequency of cereal crops was 33 per cent increased wheat yields by about 0.2 tonnes per hectare and wheat grain protein content by 0.9 to 1.6 per cent, when compared with continuous cereal or continuous wheat rotations, he said.
It's the best way to optimize the rotation," Schaumburg Transportation Director Karen Robles said Thursday at the O'Hare Noise Compatibility Commission's Fly Quiet committee meeting.
In Section 2, we resolve the problem of the correct interpretation of 3D gyroscope measurements by invoking the expressions for the rotation that is equivalent to the three simultaneous orthogonal rotations measured by a 3D gyroscope, as derived in [30], and present proper means for computing the angular orientation.
