Extension tests

Finally, preliminary diagnostic evaluation criteria, based on preventive identification of critical areas of interest on the monitored item, spatial concentration of localized AE events as compared with average AE event density and evolution of local event concentration vs time and/or plant parameters, have been worked out and submitted to extensive testing under real operation conditions. Work on this very critical issue is still to be consohdated. 

It must be realized that it may eventually be necessary to undo twentieth century repairs, just as past restorations often need to be removed. A common reason is that the materials used ia restoration may have aged with unacceptable visual consequences. If the removal of the proposed repairs should ever be necessary for whatever reason, it should be possible without danger to the object. Consequentiy, extensive testing of the stabiUty of the materials used for the treatment is needed. 

Subsequent to processing, an inspection is made for incomplete bonding, inside dirt, and glass quaUty. In the case of windshields, rigid optical standards must be met, and these must be evaluated for the completed windshield. Extensive test requirements are described in the appropriate codes (11,12,15,18—24), and they include light stabiUty, resistance to optical distortion, humidity, boil test, abrasion resistance, and assorted impact tests. 

All pesticide products created for use by homeowners and farmers in the U.S. must be registered by EPA. This process includes extensive testing to determine the toxicity of the product and its potential for threatening the... 

The activity of ivermectin against the filarial parasite Dirofilaria immitis in dogs suggested a possible role for the control of filarial parasites of humans (20). It has been extensively tested in human onchocerciasis and is now considered to be the dmg of choice. In a single yearly oral dose, it suppresses microfilariae in the skin and eyes and, in most cases, prevents the progression of the disease to blindness. Table 4 shows the results of a 30-patient double-blind study recorded over one year. 

Most users require extensive composite qualification testing programs to assure acceptable end use product properties. The magnitude of the qualification depends entirely on the end use requirements and may range from extensive testing of laminates and final parts made from several production lots of fiber, to a single lot laminate evaluation or test coupon verification of properties. 

System Characterization. After all the components are assembled to produce a dmg dehvery system, extensive testing is performed to ensure that the performance and stabiUty of the dmg dehvery system meet specifications. 

Although the traditional point of reference for safety interlock systems is a hard-wired implementation, a programmed implementation is an alternative. The potential for latent defects in software implementation is a definite concern. Another concern is that solid-state components are not guaranteed to fail to the safe state. The former is addressed by extensive testing the latter is addressed by manufacturer-supplied and/or user-supplied diagnostics that are routinely executed by the processor within the safety interlock system. Although issues must be addressed in programmable implementations, the hard-wired implementations are not perfect either. 

Some tolled products can be reworked if they fail quality assurance tests. In these cases the production cost may go up, but the product is not a complete loss. However, other tolled products, some pharmaceuticals for example, could be completely ruined by similar processing mishaps. Losses in these cases can be quite extensive. Test runs and approved rework procedures for such products may help avoid these losses. 

Wood-fired power boilers are generally found at the mills where wood products are manufactured. They are fired with waste materials from the process, such as "hogged wood," sander dust, sawdust, bark, or process trim. Little information is available on gaseous emissions from wood-fired boilers, but extensive tests of particulate matter emissions are reported (19). These emissions range from 0.057 to 1.626 gm per dry standard cubic meter, with an average of 0.343 reported for 135 tests. Collection devices for particulate matter from wood-fired boilers are shown in Table 30-21. 

Extensive tests have shown that if the final creep strain is not large then a graph of Fractional Recovery against Reduced Time is a master curve which... 

For this expression to be valid, in cell A components 1 and 2 must be identical in all respects, so it is a rather special case of an ideal mixture. They are however, allowed to interact differently with the membrane, as described above, xa is the mole fraction of the solute in cell A, while p and p are the number densities of cells A and B respectively. The method was extensively tested against both Monte Carlo and equations of state for LJ particles, and the values of the chemical potential were found to be satisfactory. The method can also be extended to mixtures [29] by making... 

In almost all cases, if a flame arrester is placed in-line rather than at (or close to) the open end of a vent pipe, a detonation flame arrester is needed. Detonation flame arresters mnst be able to stop both deflagrations and detonations. They require extensive testing and mandatory testing protocols may apply. 

The Fractionation Research, Inc. design procedures are proprietary for the financial participants in this extensive test program. 

The multivariable modeling/control package is able to hold more tightly against constraints and recover more quickly from disturbances. This results in an incremental capacity used to justify multivariable control. An extensive test run is necessary to measure the response of unit variables. 

From a consideration of Table 3.10, a copper-phosphorus steel might be chosen for its resistance to corrosion in the critical tidal and splash zone. However, the variation of corrosion resistance is much greater than the difference between various alloy steels so it is improbable that low-alloy steels will corrode more slowly than mild steel in most practical environments. This conclusion is supported by Forgeson etal. who concluded from extensive tests in fresh and salt waters of the Panama Canal Zone that Proprietary low-alloy steels were not in general more resistant to underwater corrosion than the mild unalloyed carbon steel . ... 

As the protective value of the zinc coating depends largely on the corrosion resistance of zinc, the life of a coating is governed almost entirely by its thickness and by the severity of the corrosive conditions to which it is exposed. Extensive tests and field trials which have been carried out have shown that the life of a zinc coating is roughly proportional to its thickness in any particular environment and is independent of the method of application. 

Paints have their own individual data sheets, prepared by the manufacturer as the result of extensive testing including laboratory tests, field trials and experience in use. These instructions should be followed closely in respect of type of application equipment, operating air pressure, tip size, pot life, curing time at various temperatures, recoating interval, etc. The inspector should have the data sheets available at all times and refer to them.

FIGURE 8.14 Simulation for 5,000 theoretical ligands with calculated efficacy (Equation 8.11) and affinity (Equation 8.10). It can be seen that efficacy and affinity are correlated suggesting that all ligands that have been shown to bind to a receptor should be extensively tested for possible efficacy effects on the receptor directly, through agonist-effects on the receptor or changes in constitutive behavior of the receptor itself. Redrawn from [15]. 

Those familiar with processing can detect and correct visible problems or readily measure factors such as color, surface condition, and dimension. However, less-apparent property changes are another matter. These may not show up until the products are in service, unless extensive testing and quality control are used. 

Boats have been designed and built up to at least 37 x 9 m (120 x 30 ft.) in RP. Plastics have become vital for operating within the sea. In 1965 extensive test were conducted by the U.S. Navy Sealab 11 to assay man s ability to live and work in ocean depths for long periods of time (Fig. 2-56). For forty-five days three groups of ten men each lived fifteen-day periods in a 57 ft. x 12 ft. habitat at a depth of 188 m (205 ft.) one half mile off La Jolla, Calif. Plastic parts as well as other materials were used to provide a highly successful experiment.
