A search for free core nutation modes in VLBI nutation observations
Physics of the Earth and Planetary Interiors, 1995Abstract In recent decades much effort has been devoted to searching observations for evidence of free core nutations predicted by theoretical models. Polar phototube data, tidal gravity observations and very long baseline nutation measurements have all been used.

Image processing by nutation: an analysis
Applied Optics, 1976Enhancement of blurred images by nutation involves accumulation of information from displaced replicas of the degraded image. The technique is analyzed theoretically and is found to be equivalent to convolution with the weight distribution assigned to the replicas.

“Nutation” of electron spins in biradicals
Journal of Magnetic ResonanceIn this work, the nutation of the spins of unpaired electrons in the nitroxide biradical of bis‑methano[60]fullerene was experimentally studied. Nutation frequencies were found in a wide range of microwave field power. To interpret the obtained results, numerical calculations of the nutation of biradicals were carried out for a set of parameters of the

INITIATION OF NUTATION IN SUNFLOWER HYPOCOTYLS
1981Publisher Summary This chapter discusses the initiation of nutation in sunflower hypocotyls. If, prior to the onset of nutating activity, one could see random walk type movements by the epicotyl that in time grow large enough to elicit a gravitropic response with overshoot, then one should interpret this as additional support for the validity of ...

Im ersten Teil dieser Arbeit (Elemente d. N. 25 ) wurde an einer Reihe von Tatsachen dargestellt, dass die organischen Gestalten nicht ruhende, feste Formen Wie z. B. die Kristalle sind, sondern dass sie ihr Dasein einem ständig sich verwirklichenden Geschehen im Strome des Stoffwechsels verdanken.
