In PWRs - a different LWR system - control rods are withdrawn from the core, and the control is acheived with soluble B-10 in the coolant (which is buffered with LiOH) to maintain a pH above 6.9 or perhaps closer to 7.1 - 7.4 for purposes of minimizing the accumulation of crud (metal corrosion products) on the fuel.
Rhetorical patterns have an additional function of helping writers to organize information in ways their readers can understand easily (425). Another term for these patterns is topoi (commonplaces). Many of these topoi are useful in numerous situations.
A rhetorical pattern is a technique that is used by a writer, or in some cases, a speaker, to communicate ideas in a particular way. Readers or listeners use an understanding of rhetorical patterns to try to develop a closer analysis of what the writer or speaker is trying to express.xperts point out that the placement of an example of other rhetorical pattern is important in revealing more about the writerâs intent and what he or she is trying to express. Comparing and contrasting is another kind of rhetorical pattern that writers might use.
