Practically eliminated condition

Face checking of plywood and parallel laminates, with phenolic resin treated faces, is practically eliminated on indoor exposure. Under out-of-doors weathering conditions face checking and erosion are materially reduced (9). 

Deflection Potentiometer Method.—A potentiometer is ordinarily used as a null instrument. The electromotive force of the couple is exactly balanced by the potential drop over a resistance through which a current from a battery is flowing. No current flows through the couple circuit when the proper setting is obtained. This condition is indicated by zero deflection of the galvanometer in series with the couple. The objection sometimes raised against the ordinary potentiometer for industrial installations is that it requires a manual adjustment of a dial or slide wire every time an observation is made. This objection is practically eliminated in the deflection potentiometer which may be constructed so that it embodies the accuracy of the ordinary potentiometer and the convenience of the galvanometer indicator. 

Figure 9 shows the curve for tobacco residues purified by TLC before analysis by the assay. It is clear that the interference seen previously was practically eliminated. However, such extensive sample preparation makes use of this assay in its present form cumbersome, at best. We are presently investigating an alternative form of immunoassay, the enzyme immunoassay (EIA) ( , 21) In this assay methoprene is conjugated directly to an enzyme and the anti-methoprene antibody is bound to the solid support. Free methoprene and methoprene-enzyme conjugate are in solution and compete for immobilized antibody binding sites. Unbound methoprene is washed from the assay prior to addition of substrate. Preliminary results under these conditions indicate that tobacco extracts of acetonitrile/water (9 1) do not require further purification steps prior to application to the EIA. 

A characteristic peculiarity of the DBTDB radiation-chemical synthesis is the induction period (I, 2, 3). Many different methods have been used, and optimum conditions for the reaction have been found, which practically eliminates the induction period. One method was the above-mentioned treatment of tin powder. Another highly effective method was the introduction of diverse activators like water or n-butyl alcohol. Figure 2 shows the DBTDB content curves in relation to the amount of activator. 

The difficulty becomes accentuated by several other requirements that cannot be achieved through the selection of a single filter medium. Therefore, selection is often reduced to determining the most reasonable compromise between different, mutually contradictory requirements as applied to the filter medium at a specified set of filtration conditions. Because of this, some problems should be solved before final medium selection. For example, should attempts be made to increase filtration rate or filtrate purity Is cost or medium life more important In some cases a relatively more expensive filter medium, such as a synthetic cloth, is only suitable under certain filtration conditions, which practically eliminates any cost consideration in the selection process. 

Safety assurance practical elimination of release of radioactive materials at normal operation and accidental conditions. 

A higher value of kgg indicates a high free radical concentration in the system, which can result in a higher degree of chain termination whereas a low kgg indicates a low radical concentration that will slow down the rate of polymerization. Under optimized ATRP conditions, a relatively lower kgg value will be normally maintained, which practically eliminates the undesired chain termination and results in the formation of polymers with narrow molecular weight distributions. A variety of functional monomers such as styrene, acrylates, acrylamides, vinyl acetate, vinyl pyridine, and vinyl pyrrolidone can be conveniently polymerized using this technique [79, 80]. 

Criterion 20. Design extension conditions Limited set of events more severe than DBAs [station blackout, anticipated transients without scram (ATWS), aircraft impact, etc.] for design extension requirements. The design shall be such that design extension conditions that could lead to significant radioactive releases are practically eliminated. 

The brief information reported indicated the great variety of the reactions of synthesis of regular LC polymers. The variations of the conditions of conducting the reactions are limited by the requirement of chemical stability of the polymer chain, however. In synthesis of irregular LC polymers (with irregular alternation of rigid and flexible fragments), this restriction is practically eliminated. 

DC electrochemical potentials (Section 1-3). This modification results in the practical elimination of the capacitive contributions to the bulk solution impedance for AC frequencies under -100 MHz, as the bulk solution resistance is decreased to an extent that all current in the bulk solution passes through However, even this condition does not always fulfill the criteri-on — 0. 

All numerical computations inevitably involve round-off errors. This error increases as the number of calculations in the solution procedure is increased. Therefore, in practice, successive mesh refinements that increase the number of finite element calculations do not necessarily lead to more accurate solutions. However, one may assume a theoretical situation where the rounding error is eliminated. In this case successive reduction in size of elements in the mesh should improve the accuracy of the finite element solution. Therefore, using a P C" element with sufficient orders of interpolation and continuity, at the limit (i.e. when element dimensions tend to zero), an exact solution should be obtaiiied. This has been shown to be true for linear elliptic problems (Strang and Fix, 1973) where an optimal convergence is achieved if the following conditions are satisfied ... 

The usual practice is to blend cmde oils of similar characteristics, although fluctuations ia the properties of the iadividual cmde oils may cause significant variations ia the properties of the blend over a period of time. Blending several cmde oils prior to refining can eliminate the frequent need to change the processiag conditions that maybe requited to process each of the cmde oils iadividually.
