Local depressions

Local depressions are caused by local inadequate compaction of the unbound layers or failure of the subgrade. When accompanied by cracks, fatigue of asphalt layers has also [Pg.652]

Local depressions with less than 20 mm maximum depression depth may be treated by micro-surfacing (temporary maintenance). [Pg.652]

When the depression depth is higher than approximately 20 mm, determine the cause and repair by removing and replacing the affected pavement to the required depth. [Pg.652]


Dialysis is not currently performed on samples intended to be applied on buffered supporting media. Theoretically, however, this precaution should be taken because increased conductivity, increased ionic strength, and modification of pH cause several disturbances at the application spot, the most important being local depression of the electric field intensity (G10). Some substitute for dialysis is realized if the sample is diluted with a solution of buffer and serum salts, with volume and concentration calculated to give a final salt concentration corresponding to the expected result of combined dialysis and dilution (S31). This method was successful for free electrophoresis of serum and should also be useful in zone electrophoresis on stabilizing media. [Pg.40]

Mechanism-specific adverse effects. Since local anesthetics block Na+ influx not only in sensory nerves but also in other excitable tissues (A and p.206), they are applied locally. Depression of excitatory processes in the heart, while undesired during local anesthesia, can be put to therapeutic use in cardiac arrhythmias (p.138). [Pg.202]

Lake Pontchartraln is a shallow, open water embayment of a major estuarine system in southeastern Louisiana. It has surface area of approximately 630 square miles (1.60 x 10 m ). Depths in offshore areas (greater than one mile from shore) range typically from 12-18 feet (4 to 6 m) with the bottom exhibiting a gradual relief. Localized depressions proximate to three tidal passes, which connect the lake to the Gulf of Mexico, slope to depths up to 40 feet (12m). The passes themselves have depths approaching 100 feet (30m). [Pg.248]

Adaptive changes in deiodinase activity have been reported in certain regions of the brain of fetal rats exposed in utero to the PCB mixture Aroclor in order to compensate the local depression ofT4 levels (Morse et al, 1996). In chicken embryos, in ovo exposure to PCB77 temporarily reduced TH levels (Roelens et al., 2005) both in plasma and brain areas, which was combined with an adaptive increase in the activity of the type 2 deiodinase activity and decrease in activity of the T3 inactivating type 3 deiodinase Beck V. (2006). [Pg.299]

However, cut-back bitumens and, to a lesser extent, fluxed bitumens used to be extensively used in the past, mainly for the production of open or semi-dense graded bituminous mixtures. Today, their use is limited to prime coating, to in situ production of cold/semi-warm bituminous mixtures particularly in remote areas away from a hot mix plant and to the production of ready-mixed bituminous mix for repairing-filling works (potholes, utility cuts, local depressions, etc.). [Pg.113]

Distortions may take one of the following forms (a) rutting, (b) corrugations and shoving, (c) local depressions or (d) upheaval. Figure 15.12 shows schematically the different forms of surface distortion. [Pg.648]

Local depressions are localised areas with slightly lower elevations than the rest of the surrounding pavement (Figure 15.12d). They are more easily noticeable after rain. [Pg.652]

The physical phenomenon behind this law is explained as the effect of the convergence of velocities in fluid elements in a point, that is mathematically expressed by the operator minus divergence = convergence, which creates a local pressure and dissipates the energy into heat. The inverse effect, a negative convergence, or positive divergence, creates a local depression and still dissipates. [Pg.450]

The Hamr deposit occurs in a Cretaceous basin of the Bohemian Massif, in Cenomanian sandstones of continental to epicontinental facies. Uraniferous mineralization occurs in coarse sandstones interfingered with siltites, covered with lutites, in local depressions and generally close to the unconformity. The... [Pg.157]

Q.p = 9970 cm-1 (1.17 eV), 1/t = 4340 cm- (0.51 eV), and fcf A = 1.6 with an assumption of C = 1. These parameters are reasonable. The plasma frequency is close to that obtained from the reflectance minimum ( 1.4 eV) and the peak in the loss function ( 1.1 eV). The value of fcf A (= 1.6) indicates that PANI-CSA is not a good metal [1160]. Instead, this fact supports that PANI-CSA is on the metal-insulator boundary and approaching the loffe-Regel limit. Moreover, the deviations from simple Drude behavior in the far-IR are quantitatively consistent with the LMD model [1160, 1161]. As indicated by Eq. (4.18), localization depresses o(w) below the Drude curve in the far-IR. [Pg.72]

The effect of a local increase of the potential drop at the oxide surface is similar to the situation discussed for the adsorption mechanism of Section 7.4.3 and Figure 7.2c. Apparently, the defects lead to locally enhanced dissolution, however, with still maintained passivity (Figure 7.10a). Statistical fluctuations may cause even an intermediate localized activation, which, however, will not last due to the self-healing effect of passive surfaces. However, they cause local depressions at the specimen surface. Temporary local breakdown should therefore be accepted also for electrolytes free of aggressive anions. This concept is consistent with an increased general corrosion rate during the early stages of passivation that will decrease with time when the film structure becomes more crystalline with a related decrease of its defects. [Pg.367]
