Similarly the boundary plane [S.sup.2], which is characterized by the radiative properties [[rho].sub.2v], [[epsilon].sub.2v], and [[tau].sub.2v] = (1 - [[epsilon].sub.2v]) (1 - [[rho].sub.2v]), scatters, absorbs, and transmits the radiation of intensities [mathematical expression not reproducible] incident on it from the volume V and external medium correspondingly.
The intensities of radiation emitting by the planes [S.sub.1], [S.sup.2] into the volume V and in external medium are defined as [mathematical expression not reproducible], correspondingly.
The second term in the right-hand part of the relations (9) takes into account the internal radiation, passing through the boundary into the external medium, whereas the last term in this part determines the spectral intensities of the external radiation, reflecting back into external medium by the boundary.
Thereafter, mesogleal calcium concentration remained significantly higher than concentrations in tissue or in the external medium. Overlap of standard deviations associated with calcium levels of the medium at 20 [per thousands] and 12 [per thousands] [ILLUSTRATION FOR FIGURE 2C OMITTED] rendered calcium data from experiment 2 equivocal.
All animals at 12 [per thousands]-20 [per thousands] exhibited overlap between seawater and mesogleal osmolality, although paired t-tests indicated that the osmolality of mesogleal fluid was significantly lower than that of the corresponding external medium at 15 [per thousands] and 20 [per thousands] (P [less than] 0.05).
In all cases, mesogleal sulfate levels were significantly lower than levels in the external medium.
