Digital-age problems

I m not talidng about fun you can have at an amusement park, but CRE fun. Now that we have an understanding on how to solve for the exit concentrations of multiple reactions in a CSTR and how to plot the species concentration down the length of a PER or PER, we can address one of the most important and fun areas of chemical reaction engineering. This area, discussed in Section 6.1, is learning how to maximize the desired product and minimize the undesired product. It is this area that can make or break a chemical process financially. It is also an area that requires creativity in designing the reactor schemes and feed conditions that will maximize profits. Here you can mix and match reactors, feed steams, and side streams as well as vary the ratios of feed concentration in order to maximize or minimize the selectivity of a particular species. Problems of this type are what I call digital-age problems - because... 

PlO-27. This problem encompasses the effects of catalyst decay with heat effects and is a t ical digital age problem.

There also are numerous highly regarded, creative, and sophisticated tests to assess attention, concentration, and ECF, and these tests usually have manuals with age-corrected norms and sometimes provide sample test profiles of people with drug problems to compare with your client s profile. The WMS, for example, has a section that assesses attention and concentration in addition to memory functions. Another well-known attention and concentration test is the Symbol-Digit Modalities Test (Smith, 1991). Some of the more well-known measures of ECF and related cognitive functions include the Wisconsin Card Sorting...
