ATPE interacts in multidisciplinary work-teams with the help of mentors, a situation that occurs during the third stage of the program.
Composed of 16 questions, the initial questionnaire (open) was sent by email to 114 engineer-trainees from two classes of ATPE in October 2008.
In the script for the trainees' interview, 11 questions attempted to capture views about the ATPE, the teamwork in the third step of the Program; the interaction with colleagues and mentors; negotiation of new ideas; learning; facilitators and difficult aspects of learning in the ATPE.
The guiding criteria were: (a) presence of concepts from the Theoretical Reference Model in terms and expressions of similar spelling or even semantic meaning; and (b) presence of other words and expressions that characterize learning in ATPE.
2] coated with ATPE were generally more brittle, yet still generated peak force data greater than that assoc iated with uncoated filler.
Crystallinity data for the high molar mass ATPE coating is intermediate to the trends for decanoic and behenic acids.
Polymeric ATPE coatings are exceptional in this respect; while excellent levels of dispersion are achieved, specific energy increases relative to the use of uncoated filler, as a result of greater physical interaction between the long aliphatic chain coating and the MDPE polymer.
Application of the polymeric ATPE coating has produced results that are in some respects significantly different from those relating to short chain fatty acid coatings, even though the reaction mechanism with the inorganic filler is identical.
As was the case in the laboratory-scale blending unit, the ATPE coating was characterized by significantly higher CH/OH ratios, owing to the long chain nature of the polymeric coating reducing the OH-absorption peak.
A similar representation of FTIR data for ATPE coating (using CH/OH peak height ratios) is inappropriate.
At coating levels higher than 10% ATPE, it was noted that the blended samples were "gritty" in nature, which is due to the chains of the ATPE having been melted and subsequently cooled during the coating process, producing small particles of what are, in effect, "highly-filled polymer composites.
But some still doubt that the increased involvement of groups like ATPE and the Texas Parent PAC in the state board races will swing their outcomes.
