For the analysis of surface loading with increase in temperature, the phenol solutions of different concentration (Co = 50, 100, 150, 200, 250 mg/l) were prepared in five conical flasks.
The design of underground spaces in urban areas must account not only for the current overburden load but also for future surface loads, such as from construction of high-rise buildings above underground structures.
However, an increased height of the contact zone enhanced the higher, plug flow region and a recommended height of 0.81 m or higher for the recommended hydraulic surface loading was suggested when both mixing and plug-flow are desired.
This new theory assumes the variation of the activation energy for surface diffusion with surface loading, and it is validated with diffusion data of propane, n-butane, n-hexane, benzene and ethanol in activated carbon.
The metrics of presentation of results for toxicants in dust surface loading (micrograms per square centimeter) or surface concentration (micrograms per gram) are discussed.
TEM revealed surface loading occurred for each core size.
In the absence of dust-fall standards, the results were compared with the U.S. Environmental Protection Agency's (U.S. EPA's) dust-lead surface loading standard for interior residential floors (40 micro g/ft2, equivalent to 431 micro g/m2); daily lead dust fall during demolition exceeded the U.S. EPA floor standard by 6-fold on average and as much as 81-fold on an individual sample basis.
Another likely explanation for the high magnetite dissolution is surface loading of Fe(II) from dissolved Fe(II).
The approach taken here is to use the elasticity solution of Pagano and Srinivas and Rao for surface traction loading of a layered, orthotropic simply supported body, and to vary the pressure distribution iteratively to achieve the best fit between the calculated surface displacements and the indentor profile.
Moreover, the applicability of solutions using the series expansion method for stresses near surface load areas is also examined.
