His mind was concrete and moved with difficulty in regions of the abstract; but, even when he could not follow the reasoning, it gave him a curious pleasure to follow the tortuosities of thoughts that threaded their nimble way on the edge of the incomprehensible.
The tortuosities of the hybrid preforms agree with those of the carbon and glass preforms, in which Hybrid 1 results in 2.15 and 2.14 for Hybrid 2 (intermediate values compared with nonhybrid laminates).
For the Springer shale, MICP tests provide the pore structure results including bulk and particle densities, porosity, pore-throat size distribution, permeability, and both effective and geometrical tortuosities (shown in Table 2); the effective tortuosity ([D.sub.0]/[D.sub.e]) is related to the extent of diffusive mass transfer while geometrical tortuosity ([L.sub.e]/L) to tortuous pathways [11, 13].
Then, the studied phases can be separately characterized by histograms of tortuosities in the corresponding directions of propagation.
Male subjects and those under treatment were more likely to show severe tortuosities. In some cases, group B subjects had blood vessels visible under the slit lamp.

This is not the case for the 100 cm starting condition: closest approach, path tortuosities, distance traveled, and time to closest approach for the normal and reversed sensors are not significantly different and in fact are numerically similar.
