There was a positive correlation for VO2max with diffusion tensor imaging (DTI) metrics of fractional anisotropy in about 54 percent of WM fiber tracts, and a negative correlation with mean and radial diffusivities
in about 46 and about 56 percent, respectively, of the WM fiber tracts.
Within the range of microwave output levers (200,280,460, and 640 w), effective moisture diffusivities
were found to be 3.318 x [10.sup.-9] to 1.073 x [10.sup.-8] [m.sup.2]/s and activation energywas estimated to be 4.111 W/g.
Figure 4 shows the average axial and transverse thermal diffusivities
and relative standard deviations of MG with and without the HTP process.

of silver nanoparticle colloidal suspensions by means of a frequency-resolved thermal lensing approach," Optics Expresss, vol.
Yet, the difference between the two diffusivities
is not very large showing that [H.sup.0](2) in intrinsic Si gives a small but significant contribution to the total concentration.
Note also that in permeation processes with penetrant diffusivities
D in the [10.sup.-6] [cm.sup.2]/s order, using film samples with thickness L in the 10 [micro]m range, time lag values are in the few-second order in which the result is thus comparable to that of the response time of the low-pressure gauges.
Before measuring the thermal diffusivity of the Ag nanofluids, the thermal wavelength method was applied to measure the thermal diffusivities
of some liquids, such as distilled water, glycerol, and two different types of cooking oil.
Calculation of effective diffusivities
for biofilms and tissues.
However, the values of the densities, specific heat capacities and thermal diffusivities
of the samples were found to change as the compacting pressure increased due to decreased in porosity.
where where [f.sub.+], [f.sub.-] are the diffusivities
perpendicular and parallel to structure orientations.
Dye-release studies have consistently found isopycnal diffusivities
O(1) [m.sup.2] [s.sup.-1] at 1-5-km scales, an order of magnitude larger than could be inferred from YRG82 theory (Ledwell et al.
