Orientation representing degree/type

A second problem was that we would have no way of knowing the degree of representativeness of the groups we studied, though we could attempt to sample a variety of the types of groups (oriented toward sex, magic, mysticism, etc.) that our informal explorations suggested. 

These theoretical considerations have led to the following view on a nematic solution, in particular of a solution of a para-aromatic polyamide in sulfuric acid [38]. In a quiescent solution of a lyotropic polymer the chains are more or less aligned parallel inside domains of microscopic size, see Fig. 3. The degree of orientation inside the domain, as represented by the order parameter (Pj), is determined by the concentration and temperature. The excluded volume entropy term leads to the formation of oriented blobs with a size of the order of Lp, the persistence length. These blobs line up due to their anisotropic polarizability, which implies that the formation of the anisotropic phase is governed by a dipole-dipole type of interaction, immediately leading to the Maier-Saupe mean-field potential. The entropy or excluded volume interaction merely tells us... 

Type R random orientation of the crystal grains representing the degree of imperfection in the spherulitic crystalline texture. The orientation distribution function is given by equation (39).
