D distribution

The D-T2 experiments were performed [51] for a Berea sandstone sample at a proton Larmor frequency of 1.74 MHz and a static gradient of 13 G cm-1. The sample was first vacuum saturated with brine, then centrifuged when immersed in oil resulting in a saturated mixture of oil and water. A D-T2 map was obtained using FLI, shown in Figure 2.7.5. The T2 and D distributions were obtained by... 

Using the previous equations and the calculated P/t- ratios, we can determine the angular shapes of the /detection( d) distribution for m J = 0, 1, or 2. The resulting distributions are shown in Fig. 4. Note that since the ratios of V k were used, the absolute scale is arbitrary only the relative shapes and magnitudes are important. We then fit the angular distribution data to a sum of these functions multiplied by the /dissociation term to obtain the relative m,j populations and the / value ...

With the above-described heat transfer model and rapid solidification kinetic model, along with the related process parameters and thermophysical properties of atomization gases (Tables 2.6 and 2.7) and metals/alloys (Tables 2.8,2.9,2.10 and 2.11), the 2-D distributions of transient droplet temperatures, cooling rates, achievable undercoolings, and solid fractions in the spray can be calculated, once the initial droplet sizes, temperatures, and velocities are established by the modeling of the atomization stage, as discussed in the previous subsection. For the implementation of the heat transfer model and the rapid solidification kinetic model, finite difference methods or finite element methods may be used. To characterize the entire size distribution of droplets, some specific droplet sizes (forexample,.D0 16,Z>05, andZ)0 84) are to be considered in the calculations of the 2-D motion, cooling and solidification histories. 

It is not possible, using 2-D imaging, to obtain complete certainty as to whether the nanoparticles lie on the surface of the sections, or have actually penetrated the cell. It is therefore necessary to use 3-D microscopy techniques such as confocal microscopy or 3-D tomography to determine the 3-D distributions of the particles. In general a number of complementary techniques must be utilized to fully understand the 3-D distribution and structure of the nanoparticles/tubes within the cell. 

Other Springer model derivatives include those of Ge and Yi, ° van Bussel et al., Wohr and co-workers, and Hertwig et al. Here, the models described above are slightly modified. The model of Hertwig et al. includes both diffusive and convective transport in the membrane. It also uses a simplified two-phase flow model and shows 3-D distributions...

Restricted diffusion also limits tissue distribution after intraparenchymal drug administration, as shown in Figure 2.7c and d. Distribution has been measured in the rat brain after implantation of polymer discs containing NGF [66]. Drug concentrations decreased to less than 10% of the values measured on the disc surface within a distance of 2-3 mm, even after prolonged periods of several days. Therefore, applying this approach in the larger human brain would require the stereotaxic placement of multiple intraparenchymal depots, as has been evaluated in rat brain [67], on a repetitive schedule.

If 3-D distribution can be obtained accurately, uncertainty may still arise because some of the six assumptions are not necessarily satisfied. Sometimes the CSD does not follow a log-linear relation. Then the above theory cannot be applied. Even if the CSD follows a log-linear distribution, whether the crystal growth rate can be reliably inferred has not been verified experimentally. Higgins (2002) and Pan (2002) pointed out other possible uncertainties in applying the CSD theory.
