Release pocket

It is also accepted that after such an event, the ruptured earth surfaces may try to settle down again. It is possible that during the course of such a realignment there may still remain pockets of energy between the two plates until they finally settle. These may develop into releases of stresses once again, leading to occasional tremors or earthquakes even for. several days tifter a major earthquake or volcanic eruption. The earthquakes in Turkey are examples where two equally devastating earthquakes occurred between September and November 1999. 

Backwashing - After exhaustion, the bed is backwashed to effect a 50 percent minimum bed expansion to release any trapped air from the air pockets, minimize the compacmess of the bed, reclassify the resin particles, and purge the bed of any suspended insoluble material. Backwashing is normally carried out at 5-6 gpm/ft. However, the backwash flow rates are directly proportional to the temperature of water. 

A serrated piece of aluminum used to work a plastic laminate. Purpose of device is to compact a laminate and to break up large air pockets to permit release of entrapped air. 

The release of oil into the dike was due to boilover, that is, production of steam from the fire-fighting foam by the hot oil. As the steam leaves the tank, it brings oil with it. Boilover usually occurs when the heat from the burning oil reaches the water layer at the bottom of the tank, but in this case it occurred earlier than usual when the heat reached pockets of water trapped on the sunken roof [14].

Release of tetracycUne hydrochloride from PCL fibers was evaluated as a means of controlled administration to periodontal pockets (69). Only small amounts of the drug were released rapidly in vitro or in vivo, and poly(ethylene-co-vinyl acetate) gave superior results. Because Fickian diffusion of an ionic hydrochloride salt in a UpophiUc polymer is unlikely, and because PCL and EVA have essentially identical Fickian permeabilities, we attribute this result to leaching of the charged salt by a mechanism similar to release of proteins from EVA (73). Poly-e-caprolactone pellets have been found unsuitable for the release of methylene blue, another ionic species (74,75). In this case, blending PCL with polyvinyl alcohol (75% hydrolyzed) increased the release rate.

The amount of exogenous drug is difficult to determine. Before conducting release experiments, loaded halloysite was always washed with a large amount of water during a 5 minute rinse to ensure removal of material from the surface. However, we cannot exclude some of the active agent being attached to the outer surface of the halloysite, especially in the natural gap-defects on the cylinder surface at the end of the rolled clay sheet (it is a natural pocket on the tubule surface). The typical 5-10 % initial release burst we observed may be related to dissolution of this material.

The reason why our eyes weep copiously when peeling an onion is because the onion contains minute pockets of sulphur trioxide, S03(g). Cutting the onion releases this gas. A mammalian eye is covered with a thin film of water-based liquid ( tears ) to minimize friction with the eyelid. The tears occur in response to SO3 dissolving in this layer of water to form sulphuric acid ... 

The gas rises into the transverse colon and can form temporary pockets, which can restrict access of water to the formulation, particularly if the design does not permit uptake of water through the surface. For this reason, distal release of drug can be hampered by poor wetting/spreading and the reduced surface area, leading to restricted absorption.
