What's the difference between lutation and nutation?
Lutation
Definition:
(n.) The act or method of luting vessels.
Example Sentences:
Nutation
Definition:
(n.) The act of nodding.
(n.) A very small libratory motion of the earth's axis, by which its inclination to the plane of the ecliptic is constantly varying by a small amount.
(n.) The motion of a flower in following the apparent movement of the sun, from the east in the morning to the west in the evening.
(n.) Circumnutation.
Example Sentences:
(1) The effect on the signal intensities of cerebrospinal fluid (CSF) and iophendylate (Pantopaque) and on CSF-iophendylate contrast was studied in vitro with a small-nutation-angle (alpha) gradient refocused magnetic resonance (MR) imaging technique (GRASS) as alpha, repetition time (TR), and echo time (TE) were varied.
(2) 2D 27Al nutation MAS NMR was used to corroborate the line assignment for the as-synthesized and the rehydrated AlPO4-17.
(3) The families that do not show consistent differences are not necessarily harbouring nutations at the same locus, or the same mutation at any particular locus.
(4) The mutation which makes T7 DNA sensitive to the endonuclease is separable from the amber nutation and located between am28 and am233 (gene 6).
(5) Solid-state 27Al NMR spectra of several aluminophosphate molecular sieves have been recorded with conventional magic-angle spinning (MAS), double-rotation (DOR) and quadrupole nutation with fast MAS.
(6) Enhanced resolution was obtained in the quadrupole nutation experiment at certain radiofrequency pulse strengths.
(7) There was a high correlation between measurements obtained with the variable nutation and partial saturation techniques.
(8) The one phase is the intermediate phase where dilatation of the cervix is almost complete and where there is an instinctive reflex that delivery is going to take place and this is very strong, and this is what starts off the oscillation (contra-nutation) of the sacrum and full engagement.
(9) The apparent T2 is influenced by the magnitude of the nutation angle inhomogeneity across the slice and paradoxically is not always more accurate with larger numbers of echoes.
(10) The accuracy of measurement of the spin-lattice relaxation time (T1) in biological systems using the variable nutation angle method is discussed using computer simulations.
(11) The spin nutation properties of frequency selective (space selective in combination with a magnetic field gradient) trains of radiofrequency micropulses were studied in a numeric model.
(12) Cross-polarization magic-angle spinning 13C and 15N NMR, rotational-echo double resonance 13C NMR, and delays alternating with nutation for tailored excitation-difference 13C NMR spectra have been obtained from lyophilized cell walls of Bacillus subtilis grown on a synthetic medium containing D,L-[2-13C, 15N]aspartate and D-[1-13C]alanine.
(13) Transparent pulses are defined by the property of having no net effect on stationary spins, while selectively nutating and dephasing flowing spins.
(14) This "variable nutation" techniques was investigated using a T1 phantom.
(15) We conclude that the variable nutation method may allow measurement of T1 relaxation times with a significant reduction in acquisition time compared to partial saturation techniques.
