The decrease in the relative gas permeabilities
of the TX70A and TX70B blends with increasing DCP content was attributed to two aspects.
Table 3 shows the ratios of the experimental permeabilities
toward both gases for the formulated paints.
The relationship between saturated hydraulic conductivities and air permeabilities
obtained in situ, with exhumed samples tested on site and in the laboratory, has also been examined for soils of various textures (Loll et al.
The hyaloclastites have generally higher porosities and permeabilities
than the basaltic lavas and intrusions.
Areas of the mold cavity closest to the squeeze head of a high pressure molding machine will see lower permeabilities
than other areas because the sand is more closely compacted in that area as compared to other parts of the mold.
In contrast, deck sections 5 (sprayed) had average permeabilities
of 1,397 and 1,977 coulombs for the 0- to 51-mm (0- to 2-in) and 51- to 102-mm (2- to 4-in) sections, respectively.
Table 2 contains some polymer permeabilities
towards carbon dioxide.
Also, much higher steady state permeabilities
were observed than predicted by the Maxwell model.
The foamed plaster process or permeable metalcasting plaster, has been designed to produce mold permeabilities
comparable to those obtained in the Antioch process, but without the autoclaving cycle.
This new software, Absorption Systems Caco-2 Permeability Module, will supplement the permeability model now in QMPRPlus(TM), which is based on a database of about 50 measurements of permeability in human and rat, to enable pharmaceutical companies to estimate permeabilities
for very large numbers of compounds in the computer, rather than through laboratory experiments that are very costly and time-consuming.
The apparatus developed allows for the quick determination of paint film permeabilities
, not only because the conductivity values are acquired each second using a computer, but also due to the permeation cell design, which uses a minimal lower chamber volume and thus a maximum sensitivity.
