To assess the anisotropy degree of the sample from the shear wave velocity the generalized

anisotropy factor [B.sub.S] was calculated by the formula:

The ellipsoid is characterized with two parameters: the

anisotropy factor for the irregularities equaling to the ratio of ellipsoid axes [chi] = [l.sub.[parallel]]/[l.sub.[perpendicular to]] (ratio of longitudinal and transverse sizes of plasma irregularities with respect to the external magnetic field) and orientation characterizes by the inclination angle [[gamma].sub.0] of the prolate irregularities with respect to the lines of forces of an external magnetic field (sometimes with respect to horizon).

The absorption coefficient and

anisotropy factor of the second layers were chosen as minimum values given in [13] for 500-550 nm wavelengths, 0.6 ([cm.sup.-1]), and 0.87, respectively.

This function is characterized by

anisotropy factor of irregularities X = [l.sub.[parallel]]/[l.sub.[perpendicular to]](ratio of longitudinal and transverse linear scales of plasma irregularities with respect to the external magnetic field) and the inclination angle of prolate irregularities with respect to the external magnetic field [[gamma].sub.0].

a = [square root of [[lambda].sub.[parallel]]/[[lambda].sub.[perpendicular to]]]] = thermal conductivity

anisotropy factorThe degree of orientation, or

anisotropy factor (AF), is defined as the difference between the principal values of (uu):

Beside paper--dye interaction (mainly, cross-section profile of raster element) our interest will also be focused on investigation of influence of

anisotropy factor in our model which could be important for optimization of paper components initial mixture.

The optical parameters absorption coefficient ([[micro].sub.a]), reduced scattering coefficient ([[micro].sub.s.sup.[]]) and

anisotropy factor (g) of tissues and phantoms were determined by Monte Carlo simulation technique.

Determination of

Anisotropy Factor. Firstly, brain tissue phantoms were made for comparative pictures of photon distribution.

8, the

anisotropy factor ranges from 0 for an isotropic distribution of orientation to 1 for the case of perfect domain alignment in the x-y plane.

The calculations of the [V.sub.P] range of changes within the depths of 5-25 km (5.82-6.60 km/s) with the average of 6.27-6.40 km/s allow the

anisotropy factor variations to be estimated from 4 % to 9 %, Table 5.

The

anisotropy factor, that means the ratio of in-plane conductivity and conductivity in the direction perpendicular to the pellet plane, was 328 (PANI/MMT pellet) and 6.7 (pure PANI pellet), respectively.
