In fact, as the exposure area becomes higher from the lowest tide level, chloride distribution in concrete becomes hard to be described with a single diffusion analysis since the moisture gradient in concrete simultaneously occurs during the repeated wet/dry cycles [7].
The correlation coefficient for the moisture gradient and air temperature on days with inversions reaches a statistically significant ([alpha] = 0.05) average value of 0.5.
A moisture gradient through the sapwood in the radial direction was observed owing to diffusive drying through the bark.
As expected, the drying time decreases with the increasing air temperature, so there is a greater rate of water removal from the grain because of the increased moisture gradient between the grain and the air, decreasing the time required to reduce the moisture content to the desired value for storage.
These data reveal better environmental conditions for drying samples from Treatment 1, given that higher drying temperatures result in a higher water removal rate due to the increased moisture gradient between the product and the air, as well as lower relative humidity values, which accelerate water transfer between the product and the air.
Drought stress treatment using Hsiao [14] moisture gradient design method, includes high soil moisture (mild drought stress) and low soil moisture (serve drought stress); the soil relative water content was 55%~60% and 30%~35%.
They have proposed that the drying direction (see from top, bottom, or lateral side of the specimen and so on) as well as the moisture gradient is important for the simulation of residual stresses.

Importantly, moisture gradient in coated samples is also considerably reduced.
The transient component of [DELTA][T.sub.teltd] is the sum of the temperature difference between top and bottom of slab equivalent to (producing similar response to) actual temperature gradient ([DELTA][T.sub.trans-temp-diff]) and moisture gradient ([DELTA][T.sub.trans-mots-diff]).
The results of all these evaluations showed that Aqualance[TM] (homarine and erythritol) provided a dynamic moisturizing effect which complemented the skin's natural moisture gradient. Water levels in the upper layers of the skin were rapidly increased by as much as 30%, while moisture in the deeper layers of the dermis (which naturally contains more water) increased by up to 13%.
The used numerical model based on finite volumes can be successfully applied in prediction of the moisture gradient for cross section of the laminated elements.
