Modification, effect

We have found that proper choice of curatives and the effective modification of polymer components im-... 

Microwave curing of polymeric materials requires the presence of dipolar materials for effective modification to occur through dielectric heating [45]. This is not an essence in the case of EB modification of polymers which requires the presence of only labile reactive site, e.g., hydrogen in the polymeric stmcture. 

Proposed modifications must reduce the risk to a level that is consistent with management s tolerance criteria and thus should be evaluated for effectiveness. Modifications that fail to sufficiently reduce the risk should be combined with other options or eliminated from the list of options before proceeding to an economic evaluation of the alternatives. Keep in mind that the modifications themselves may introduce new risks that need to be evaluated. 

An underlying assumption is that dextran is a representative polysaccharide and that results derived from its study can be applied to other polysaccharides. Effected modifications are intended to occur throughout the dextran material rather than only at the surface. This is achieved by employing solutions containing dissolved dextran. 

In its standard implementation, the suppression of the undesired one-bond correlations is far from complete using a one-step low-pass J filter HMBC pulse sequence. Effective modifications are needed to achieve this goal when there is a wide range of Vch values. There are several kinds of pulse... 

Although the presence of BINOL in the ligands so far discussed has shown itself to be particular effective, modification of the diol moiety provides new classes of ligands for this addition reaction. Alexakis, screening a number of chiral phosphites in the Cu(OTf)2-catalyzed 1,4-addition, showed that an ee of 40% could be obtained for the addition of Et2Zn to 2-cyclohexenone and of 65% for addition to chalcone, by using cyclic phosphites derived from diethyl tartrate [51].

The main purpose of this section is to analyse the NY correction and, as a come-out of this study, to suggest what we think is a more economical and effective modification of it (at least in the aaP-block case). 

The efiect is thus not related to geometrical constraints induced on complexes anchored in mesoporous charmels (sometimes also called as confinement efiect, even if this definition is not properly correct), neither to shape-selectivity effects as possible in zeolites, since the size of mesoporous charmels is much larger than those of micro-porous materials. Instead, an effective modification on the characteristics of the fluids is observed due to the electrostatic field generated by the charmel walls. This is an enthalpic effect versus an entropic effect as observed when the modification is instead related to limitations in the translation modes of molecules. Recently, it was also demonstrated that wall curvature influence the molecular orientation of the... 

It is therefore very likely that the lignin itself is highly modified by solvents, especially by phenols. In consequence, effective modification of lignin can be considered to enhance its reactivity. 

There have been many attempts to prepare resol resin adhesives from kraft lignin (23). Phenolation of lignin can, in these cases, also be considered a key reaction. That is, effective modification of lignin with phenol can enhance its reactivity, resulting in good gluability. 

One of the earliest methods, the full significance of which was not appreciated until many years later, was the addition of RPCb to o-dihydroxyarenes or 1,2- and 1,3-dihydroxy-alkanes (Scheme 25). For a more effective modification see (75TL1583). 

The chemical deposition of PB leads to an effective modification of the electrode surface, which then shows positive features as to hydrogen peroxide detection with an effective rate constant very similar to that measured for the peroxidase enzyme (2 x 104 M-1 s-1) [1]. Another major advantage of the chemical deposition is that it involves a more convenient and shorter procedure that avoids long electrochemical procedures during modification [2,3]. Moreover, the chemical deposition gives a more stable PB layer, which is only slightly affected by alkaline pH.

A previous trend in the paper industry of limiting starch purchases to unmodified grades and effecting modification on-site in the paper mill has changed. The variance in products thus obtained was frequently wider than in products supplied by the starch manufacturer. As a result, there is now more preference to utilize modified starches with specific application properties. Growth in paper recycling should lead to an increased use of starch as a coating binder in place of synthetic materials. 

Effectively modification of Autoanalyser procedures, sample throughput 70-200 h-1 depending on the chemistry used. Has been applied to diverse samples. Economical of reagent. 

To evaluate whether a factor is an effect modifier, one can stratify by the suspected modifier and calculate the relative risk for the putative risk factor. If the RR risk varies substantially across stratum, then an effect modification should be suspected and evaluated using statistical models, which calculate departure from additive or multiplicative effects. When studying effect modifiers, the impact of sample size on study power is very important therefore, large studies are needed to detect statistically significant interactions.
