What’s the most difficult question you’ve been asked as a maintenance instructor?
Blye Widmar
"Where are the prints?!"
This was the final question in an onslaught of verbal feedback, comments, and critiques I received from my students back in 2019. I had two years of instructor experience and was teaching a class that had been meticulously rehearsed in preparation for an accreditation visit. I knew the training material well and transferred that knowledge effectively enough for all the students to pass the class. As we wrapped up, I asked the students how they felt about my first big system-level class, and they did not hold back.
“Why was the exam from memory when we don’t work from memory in the plant?” “Why didn’t we refer to the vendor documents?” “Why didn’t we practice more on the mock-up?” And so on.

Isotherms are presented for adsorption of H2O(g) on LiAlO2 at 573, 623, and 873K together with isotherms reported earlier for 673 and 773K. From these data, isobars and isosteres were derived. Analysis of the data suggests that two adsorption processes are involved: physisorption at 573K and below, and chemisorption at 873K and above. Both processes function in the intervening temperature range. Corrections were applied to the raw adsorption data, which were obtained by the breakthrough technique, for postbreakthrough uptake of H2O(g). Adsorption on non-BET surfaces is believed to be involved in these corrections for the lower temperature isotherms.
