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.

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.

Managing clinical rotations in a manner more efficient and compliant to both professional and legal aspects proves quite challenging to most medical and educational institutions.
The nitrogen is used by subsequent crops in the rotation programme.Crop rotation will improve soil structure.
Rotation treatments significantly affected soil aggregates for both (0-5 and 5-15 cm) depths and sites.
Dr Ward said the district practice rotation in which the frequency of cereal crops was 67 per cent also resulted in higher grain yields (by about 0.4t/ha) and higher grain protein levels (by 1.2 to 1.9 per cent) when compared with continuous cereal or continuous wheat rotations.
The meeting declared that the rotation policy should be implemented across the board without any discrimination but at least three months' time may be given to the provinces or federal government, as the case may be, prior to making transfers/postings enabling the provinces to arrange their substitutes etc.
Another complexity is the fact pilots can opt out of using runways scheduled for nighttime rotation. This happened during test rotations in 2017 and 2016 when O'Hare's longest runway, stretching 13,000 feet, was often preferred for takeoffs by international cargo jets, creating a din over suburbs like Wood Dale.
And further, Venus's atmosphere is highly energetic, blowing feverishly, to go round the planet in four Earth days, while the planet takes 243 days for a rotation. The component of the energy of rotation in the whirling atmosphere of Venus is hence not negligible like it is on Earth.
In late 2016, Scott Bronson, Kathleen Harris and Scott Whisenant of the University of Kansas published a paper exploring the real effects of mandatory rotation in Italy, South Korea and Brazil.
[10] offer the solution of the task to eliminate the error in determining the north heading, which is done by exact orientation of the platform rotation axis along the local vertical.
"The rotation of the Earth does change slightly 6 by a millisecond a day sometimes 6 and that can be measured very accurately by atomic clocks," noted Bilham.
The mechanical axis was set as the axis of rotation of the femur, and we acquired the projected contours of each femoral 3D model in seven positions: 20[degrees] and 10[degrees] of internal rotation; 0[degrees] rotation; and 10[degrees], 20[degrees], 30[degrees], and 40[degrees] of external rotation [Figure 1]a.{Figure 1}
Far from being a doubtful practice, tire rotation has demonstrated in many situations to be an ideal measure for extending tire life successfully.
