Potential for collapse

To reduce the potential for collapse and to achieve greater integrity, slurry walls are usually placed in short, laterally separated panels (always for concrete walls). The primary panels use pipe or tubes at the ends, as shown in Figure 7.1. These are pulled after the backfill has set, forming a key for the secondary panels, as shown in Figure 7.2. Slurry walls made of the slurry excavated soil mixture can also be constructed continuously, by a carefully controlled procedure shown in Figure 7.3.

Figure 16-4. Potential for collapse. If the dirt wall at the sides of this excavation were to collapse, a fatality could result.

Potential for unacceptable damage—Potential for collapse during flood, safety of traveling public and neighbors, effect on regional transportation system, and safety of other facilities (other bridges, properties) need to be evaluated. 

In an attempt to increase the biorelevance of the Ussing chambers technique even further, the use of simulated intestinal fluids (FaSSIF and FeSSIF) as transport media was recently evaluated [105], However, the potential difference collapsed to zero after 120 min when exposed to FaSSIF solution and permeability for mannitol was increased twofold. Electron micrographs revealed erosion of the villi tips and substantial denudation of the microvilli after exposure of the ileal tissue to FaSSIF and FeSSIF [105],... 

A similar situation also is encountered in a miniaturized photoelectrochemical cell, i.e., on a metallized semiconductor powder, Figure 2. Here, the individual particle can be thought of as two electrochemical half cells which have eventually collapsed onto each other as the conductive wire connecting them became shorter and shorter. The oxidizing and reducing sites are thus found in close spatial proximity and the potential for subsequent chemical reaction between the initial oxidation and reduction products is excellent. In fact, so long as the respective rates of the oxidation and reduction half reactions differ appreciably, it may be unnecessary to metallize the semiconductor powder in order to... 

One of the primary problems with penicillin drugs is the potential for allergic reactions.65 Hypersensitivity to penicillin is exhibited by skin rashes, hives, itching, and difficult breathing. In some individuals, these reactions may be minor and can often be resolved by changing the type of penicillin or the method of administration. In others, however, penicillin hypersensitivity may be severe and lead to an anaphylactic reaction (severe bronchoconstriction and cardiovascular collapse). 

The Mott-Schottky regime spans about 1 V in applied bias potential for most semiconductor-electrolyte interfaces (i.e., in the region of depletion layer formation of the semiconductor space-charge layer, see above) [15]. The simple case considered here involves no mediator trap states or surface states at the interface such that the equivalent circuit of the interface essentially collapses to its most rudimentary form of Csc in series with the bulk resistance of the semiconductor. Further, in all the discussions above, it is reiterated that the redox electrolyte is sufficiently concentrated that the potential drop across the Gouy layer can be neglected. Specific adsorption and other processes at the semiconductor-electrolyte interface will influence Ffb these are discussed elsewhere [29, 30], as are anomalies related to the measurement process itself [31]. Figure 7 contains representative Mott-Schottky... 

Dissolved solids or salts in land-applied material can also create problems. They chemically collapse the clay structure, which normally allows soil to hold water. Plants will exhibit drought-like symptoms even with adequate rainfall. Applying sludge in liquid form greatly increases the potential for salt overload.
