A seasonal high water table is an example of a restrictive horizon. During a wet season, the water table may rise very close to the soil surface. It is assumed that under saturated condition, very little treatment will take place and that waste constituents could enter a drinking water ...
the process is somewhat similar. The difference is that the two wafers are bonded together by a combination of two technologies—a dielectric-to-dielectric and a metal-to-metal bond—all at room temperature. In this case, the metals include, for example, a copper-to-copper bond. Good bondin...
Performance of composites is determined by properties of a matrix, dispersed phase and interface between filler and matrix2. A filler-matrix adhesion can be modified by coupling agents. He and Jiang3showed that glass bead reinforced polyepichlorhydrin pretreated with a coupling agent yielded in an ...
Electrochemical two-electron water oxidation reaction (2e-WOR) has drawn significant attention as a promising process to achieve the continuous on-site production of hydrogen peroxide (H2O2). However, compared to the cathodic H2O2 generation, the anodic 2e-WOR is more challenging to establish catalyst...
The method presented here is also applicable to two- and three-dimensional problems of solids with holes or cavities and to similar thermoelastic problems. Application to plates with curved boundaries is also possible. 展开 关键词: power Doppler imaging color Doppler imaging color Doppler energy ...
An example of this newly developed FSIS capability is shown in Fig.6. This 2D example consists on a high explosive source (TNT) emplaced inside a disk made of rock material. Between the source and the disk and outside the disk there is air at room temperature (denoted by the blue color...
A process for separating solids from a solution of normally solid olefinic polymer, comprising filtering said solution containing solids in the presence of a filter aid and inversely varying the amount of filter aid used in relation to the melt index of the dissolved polymer , thereby obtaining ...
a poor selectivity. This means that not only are the metals of interest dissolved, but also large parts of the matrix or gangue minerals go into solution, which leads to unnecessary acid consumption and generation of impure leachates. Alkaline leaching is more selective, but not all metals of...
Among the scenarios evaluated, feasible designs are collected; and within the feasible designs, the best design that yields the lowest value in the objective function is identified as the solution to the design problem. In the beam example, we chose a 0.5 in. interval for varying the width ...
Compressive strength is an essential property in structural materials, for example, mortar, which comprises the interacial transtition zone in concrete, stone, and steel, since material design is normally evaluated in terms of the risk of compression failure. In addition the CBM is known as having...
