Simple and sensitive multi-sugar-probe gut permeability test by high-performance liquid chromatography with fluorescence labelling.
The high air-entry ceramic plate permeability is considered in analyzing the results gained from the permeability test with the modified triaxial device.
The test consisted of two basic phases after placing the specimen in a cell: (i) saturation of specimen, (ii) running permeability test. The saturation of the specimen and also the permeability measurement are carried out under the saturate pressure of 150 kPa for all tested specimens.
The average permeability reading with the new rammer was lower by comparison due to a more uniform compaction in the specimen tube, In addition, the standard deviation for permeability was 26% lower, indicating a significantly more consistent permeability test.
A 6.35-mm (.25-in) segment of the top concrete surface was sliced from two of the five cores from the sealer treated and then heavily sandblasted sectin 2 before performing the permeability test. The remaining section 2 cores were not altered.
1 to 4 are used for NMR test, and the rest are used for permeability test.
For each type of the concrete mix, three types of concrete samples, type 1 (100 x 100 x 400 [mm.sup.3]), type 2 (150 x 150 x 150 [mm.sup.3]), and type 3 (0100 x 50 [mm.sup.3]), were prepared for the freeze-thaw test, compressive strength test, and chloride ion permeability test, respectively.
For example, if you were to ask a textile or medical nonwovens person to name a permeability test, you would probably hear about the Gurley permeability first.
In a permeability test where a polyurethane glazing and construction sealant was subjected to moisture for 32 days, a PUR modified with hydrogenated polyphenyl attracted about 55% less water than a sealant modified with aromatic sulfonate ester and 12% less than one containing undecyl dodecyl phthalate.
Nuclear magnetic resonance (NMR) measurement and permeability test was carried out to evaluate the effect of microwave energy processing on pore structure and gas permeability.
[3] found that the boundary effect of crack soil also affected the permeability test precision even if CCL size was larger than 30 cm.
