In PWRs - a different LWR system - control rods are withdrawn from the core, and the control is acheived with soluble B-10 in the coolant (which is buffered with LiOH) to maintain a pH above 6.9 or perhaps closer to 7.1 -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.
Rhetoric is often defined as âthe art of language.â That might sound like a bit of a clichÃ© (which it is), but itâs actually quite a nice way of saying that rhetorical devices and figures of speech can transform an ordinary piece of writing or an everyday conversation into something much more memorable, evocative, and enjoyable.
