What's the difference between precessional and processional?
Precessional
Definition:
(a.) Of or pertaining to pression; as, the precessional movement of the equinoxes.
Example Sentences:
(1) It incorporates a stepping motor to drive the photomultiplier, two analog-to-digital converters, and a device which monitors precessional movement of the rotor.
(2) The increase of precessional motion of choline head by the inhalation anesthetic is apparently responsible for the changes.
(3) 31P NMR spectra of calf lens homogenates were obtained at 10 and 18 degrees C (below and above the cold cataract phase transition temperature, respectively) at 7.05 T. Effective rotational correlation times (tau 0,eff) for the major phosphorus metabolites present in cortical and nuclear bovine calf lens homogenates were derived from nonlinear least-squares analysis of R vs omega e (spectral intensity ratio vs precessional frequency about the effective field) data with the assumption of isotropic reorientational motion.
(4) Both CSF pulsation flow phenomena occurred secondary to harmonic modulation of proton precessional phase (temporal phase shift) by the unique pulsatile motion of spinal CSF when the repetition time was not an integral multiple of the pulsation period.
(5) Physiologic cerebrospinal fluid (CSF) pulsation causes a harmonic modulation of proton precessional phase with two-dimensional Fourier transform (2DFT) imaging, which results in predictable regions of signal loss and the presence of phase-shift images ("ghost images").
(6) Space group (P6322), parameters of the cell a-b-132 A, c = 122 A and distribution of spot intensities on precessional X-ray patterns were in full agreement with corresponding parameters for leucinaminopeptidase crystals from bovine eye lens.
Processional
Definition:
(a.) Of or pertaining to a procession; consisting in a procession.
(n.) A service book relating to ecclesiastical processions.
(n.) A hymn, or other selection, sung during a church procession; as, the processional was the 202d hymn.
Example Sentences:
(1) Pine processionary moth (Thaumetopoea pityocampa) Processional pine caterpillar tent, near Benimaurell, Alicante Province, Comunidad Valenciana, Spain.
(2) With several events planned for Hyde Park during next year's Olympics, Exhibition Road will take on a grand, processional stature.
(3) The combination of a mechanical phenomenon (penetration of the hair) and a chemical phenomenon (discharge of a toxic substance) accounts for the pathological symptomatalogy induced by the processional pine caterpillar.
(4) The processional moved throughout Louisville, visiting some of the places that bear his name: the Ali Center museum, and the boulevard named for him.
(5) In group I patients it was expressed in the absence of relapses, improvement of quality and increase in the duration of the remissions; in group II it was expressed in an increased tendency toward a regressing course with a reduced intensity of processional manifestations.
(6) The largest, most uniform and most imposing stones, carefully shaped and dressed through hundreds of hours of work with stone hammers, were set where they would be seen first by people approaching the monument from north-east along the Avenue, a processional way that would have been particularly spectacular at the midwinter sunset.
(7) English Heritage says the discovery of manmade ditches along the ancient processional route to Stonehenge is a "missing piece in the jigsaw" in our understanding of England's greatest prehistoric site.
(8) The Processional Organ Music will be J. S. Bach’s Fantasia in G (BWV 572) .
(9) Attention now turns to the Olympic Stadium, and the anticipation builds for the expected processional triumph of London 2012 poster girl Ennis, while the men's long jump, including Greg Rutherford, gets underway at 7.55pm.
