nu·ta·tion

 (no͞o-tā′shən, nyo͞o-)
n.
1. The act or an instance of nodding the head.
2. A wobble in a spinning gyroscope or other rotating body.
3. Astronomy A small periodic irregularity in the precessional motion of the earth's polar axis with respect to the pole of the ecliptic.
4. Botany A slight curving or circular movement in a stem, as of a twining plant, caused by variation in growth rates of different parts.

[Latin nūtātiō, nūtātiōn-, from nūtātus, past participle of nūtāre, frequentative of -nuere, to nod.]

nutation

(njuːˈteɪʃən)
n
1. (Astronomy) astronomy a periodic variation in the precession of the earth's axis causing the earth's poles to oscillate about their mean position
2. (General Physics) physics a periodic variation in the uniform precession of the axis of any spinning body, such as a gyroscope, about the horizontal
3. (Botany) Also called: circumnutation the spiral growth of a shoot, tendril, or similar plant organ, caused by variation in the growth rate in different parts
4. the act or an instance of nodding the head

(nuˈteɪ ʃən, nyu-)

n.
1. an act or instance of nodding one's head, esp. involuntarily or spasmodically.

Another finds that the phenomena of precession and nutation require that the earth, if not entirely solid, must at least have a shell not less than eight hundred to a thousand miles in thickness.
She said that FAO had started livelihood initiatives in 16 districts of Balochistan and provided training to male and female farmers about livestock farming for enhancing their income as well as improving their nutation status and overcoming the malnutrition issues.
In our previous works (Ron et al., 2014; Vondrak and Ron, 2010, 2015, 2016, 2017) we studied the influence of geophysical effects in nutation. To this end, we used numerical integration of Brzezinski's broad-band Liouville equations (Brzezinski, 1994) and different sources of excitations by the atmosphere (NCEP/NCAR, MERRA, ERA) and ocean (ECCO, OMCT).
The other is nutation, tiny wobbles in the planet's precession due to the gravitational tug of the Sun, Mars's moons, and other major planets on Mars.
The MOU was signed with special focus on Departments of Food Sciences and Nutation and Applied Linguistics in order to initiate student and faculty exchange programme between these two institutions.
The following techniques have been used to enhance the dark blood effect and to have a better visualization of lumen and vessel wall of the arteries: saturation band (14), double inversion recovery (DIR) (15), quadruple inversion recovery (QIR) (16), motion-sensitized driven-equilibrium (MSDE) (17), and delay alternating with nutation for tailored excitation (DANTE) (18), each method with its merits and shortcomings.
Besides, the rate of precession and nutation are synchronized and in the case [omega] = const., equal to half the magnitude of the angular velocity [OMEGA] = 2[omega].
(7,14,15) Specifically, in context of mid-labor forward sagittal tilting (nutation) of the sacrum facilitating flexion-rotation of the fetal head in the dorsal pelvic space, and thus the role of sacral dimensions, are not yet clearly elucidated.
Generally speaking, coning motion includes the nutation motion and the precession motion, which causes attitude coupled.
