  • (15) By looking at the movement of Mars, Kepler had calculated that planets orbited the sun in elliptical paths and, in a kind of celestial clockwork, his three laws of planetary motion allowed astronomers to work out the position of the planets in the future based on data from past records.

Libration


Definition:

  • (n.) The act or state of librating.
  • (n.) A real or apparent libratory motion, like that of a balance before coming to rest.

Example Sentences:

  • (1) The simulation reproduces the amplitudes of the fast librational motions of the backbone N-H bonds determined from 15N nuclear magnetic relaxation data, as well as the crystallographic B-factors.
  • (2) This has provided information on the translational and librational motions of individual groups in the complex.
  • (3) Above about 52 degrees C cholesterol improves the order by decreasing the amplitude of the librational motions.
  • (4) In its thermal vibrations, the adenosine molecule behaves as two rigid segments with a torsional libration about the glycosidic bond of 14.4 deg2 at 123 K. The force constant for this libration, as determined from the diffraction data, is 73 (10) J mol-1 deg-2.
  • (5) In the 1970s, Princeton physicist Gerald K O’Neill envisioned 100,000-person colonies, stationed at what is known as the fifth Lagrangian libration point (L5) in the moon’s orbit – like a gravitational eddy where things stay put by themselves.
  • (6) The source of the entropic elastomeric force is demonstrated to be the result of internal chain dynamics, and the mechanism is called the librational entropy mechanism of elasticity.
  • (7) The librational motions are to some extent cooperative.
  • (8) A translational, librational, and screw analysis of the thermal parameters of endothiapepsin also supports a model in which the two parts can move relative to each other.
  • (9) Collectively these results suggest that hydrophobic interactions make contributions to elastin entropy at low extensions, but that librational mechanisms make larger contributions to the elastic restoring force at longer extensions.
  • (10) Many such motions reflect peptide plane librations that result from anticorrelated crankshaft rotations of psi i and phi i+1.
  • (11) 7 nsec at 40 degrees C) where the band has been assigned to a peptide librational mode.
  • (12) The amplitude of the base motion, modeled as a fast four-site libration, or diffusion in a cone, increased slightly with higher levels of hydration.
  • (13) The TLS model has also been applied to the whole protein molecule and shows that the average motion is approximately isotropic with little librational character.
  • (14) Calculations of the relative statistical weights of these conformations confirm earlier theoretical considerations on the importance of the librational free energy of stable conformations of peptides.
  • (15) Since the spin-lattice relaxation rate for the active R-state (immobilized) phosphate is similar to that observed in other phosphoenzymes of different size it is suggested that a librational motion on the nanosecond time scale may constitute a common spin-lattice relaxation pathway for phosphates in macromolecules.
