Geometry constants

In the preceding Section (5.3) the CD bands in the near ultraviolet region are assigned to those of tyrosyl and phenylalanyl residues, whose thermal motions are restricted sterically keeping their geometry constant around the main chain in the proteins. The CD spectrum of aromatic moieties provides a good measure for the analysis of motional freedom around a given amino acid residue. Better examples have been reported on several kinds of amino acids and their polymers. 

Here, B is the magnetic field strength, mc is the critical mass (40), q is the charge of the ion in question, rm is the maximum radius required for ejection, a is the inside length of the cubic cell, r is a radial displacement, V-p is the voltage applied to the trap plates, and a = 1.3871 (49) a geometry constant.

For coating, sizing or pigmenting in film transfer presses the primary purpose of the cover is both to provide a soft nip and to transfer the applied Hquid film uniformly to the paper web. Abrasion resistance is important for keeping the nip geometry constant, as the film thickness of the applied coat/size is extremely thin and any nonconformity in the nip results in nonuniform film application. Good wettability and film splitting properties are also required.
