Synergistic interaction between

An active matrix provides the primary cracking sites. The acid sites located in the catalyst matrix are not as selective as the zeolite sites, but are able to crack larger molecules that are hindered from entering the small zeolite pores. The active matrix precracks heavy feed molecules for further cracking at the internal zeolite sites. The result is a synergistic interaction between matrix and zeolite, in which the activity attained by their combined effects can be greater than the sum of their individual effects [2J. 

A final, important distinction between sibutramine and (7-fenfluramine is that the actions of the former, but not the latter, rest on its modification of both 5-HT and noradrenergic transmission. Thus, the reduction in food intake by sibutramine is partially blocked by ai- or jSi-adrenoceptor antagonists as well as 5-HT2a/2C or 5-HT2b/2c antagonists. In fact, there appears to be a synergistic interaction between these two transmitter systems. This is illustrated by a study of the effects of the selective serotonin...

The larger is the value of Sy, the stronger is the mutual synergistic interaction between the coarse and fine particles. Also, an effective fine particle additive to improve the fluidizing characteristics of coarse particles calls for a large value of m produced with minimal amount of the fine material, that is, a small value of x2.

The only disadvantage inherent in the technique is that it takes no account of possible synergistic interaction between the osmogenes that constitute an odorous emission. Technical limitations which may be improved upon are thought to be -...

Higher concentrations of ozone in the forested areas of the eastern United States would undoubtedly cause greater injury to eastern white pine and other forest species. Chapter 11 reports additional studies that suggested that other conifer species, in particular Virginia pine and jack pine, may be more sensitive to ozone than eastern white pine. In addition, there is a synergistic interaction between low concentrations of ozone and sulfur dioxide that is the cause of the chlorotic dwarf disease... 

The fact that the differences (A-values) in the theoretical and experimental weight loss are all positive indicates that there exists some synergistic interaction between the components of the blend. Furthermore, the general trend of the A-values is consistent with that of dienophilicity of the bisdienophiles, suggesting that Diels-Alder polymerization plays an important role in the BCB/bisdienophile systems. 

Polymeric forms of ACC 71 were synthesized and their biological activities evaluated. Synergistic interactions between ACC polymers and the cytokinin 6-N-benzylaminopurine have been indicated [120].

Experiments were conducted with CrADP that also show synergistic interaction between substrate sites. These Mn-to-Cr distances were 5.9, 5.2, and 4.8 A with the CrADP, CrADP plus Ph and CrADP, P plus glutamine complexes, respectively.
