The various cabinet systems described above were all of rigid construction. Experience shows that rigid cabinets offer many advantages they are robust, can support heavy items of equipment and peripherals such as pass boxes and interface panels. However, it is practical to consider the use of plastic film isolator technology as an alternative approach to providing physical encapsulation. ... 

The cost of rigid Class III type cabinets varies depending on the size of the cabinet and the complexity of the various service interfaces and peripheral systems (pass boxes etc.) built in. Typically a simple large cabinet having no specialist modification would currently cost some 10,000-15,000 whilst more complex cabinets to contain, say, a 42 1 fermenter would cost in the region of 25,000. The cost of flexible isolators will likewise be dependent on size and complexity but one such as that in Figure 8.8 would currently cost in the region of 2,500.

If you have such a type of preamplifier to troubleshoot, check first whether or not the output lies within its linear range, without even opening the PA box. For such a purpose ... 

In this case you can go on by sending a signal to the test input, and see whether, according to Fig. 6.12, the output signal is acceptable or badly distorted. In the former case, your PA has successfully passed the simplest test and most likely it requires more sophisticated and specific procedures. If instead the output signal looks to be badly distorted or unexistlng at all, you must carry on a complete troubleshooting procedure. Open the PA box and start with dc analysis.

It is convenient to summarize the various reactions in a box diagram, such as Fig. 4.1 [17,275,280], illustrated with the equilibria of the weak base, propranolol. In Fig. 4.1 is an equation labeled pA °et. This constant refers to the octanol pKa, a term first used by Scherrer [280]. When the concentrations of the uncharged and the charged species in octanol are equal, the aqueous pH at that point defines p which is indicated for a weak acid as...
