Engineering professors, like professors in every field, have always experimented with innovative instructional methods, but traditionally little was done to link the innovations to learning theories or to evaluate them beyond anecdotal reports of student satisfaction. More scholarly approaches have become common in the past two decades as a consequence of(More)
Foam fractionation of bovine serum albumin (BSA) was studied as a model system for potato wastewater. The effects of feed concentration, superficial gas velocity, feed flow rate, bubble size, pH, and ionic strength on the enrichment and recovery of BSA were investigated in a single-stage continuous foam fractionation column. Enrichments ranged from 1.5 to(More)
Lactic acid fermentation includes several reactions in association with the microorganism growth. A kinetic study was performed of the conversion of multiple substrates to lactic acid using Lactobacillus bulgaricus. Batch experiments were performed to study the effect of different substrates (lactose, glucose, and galactose) on the overall bioreaction rate.(More)
Acetone-butanol-ethanol (ABE) fermentation was successfully carried out in an immobilized cell trickle bed reactor. The reactor was composed of two serial columns packed with Clostridium acetobutylicum ATCC 824 entrapped on the surface of natural sponge segments at a cell loading in the range of 2.03-5.56 g dry cells/g sponge. The average cell loading was(More)
The national need for engineering education reform is widely recognized. Yet, engineering faculty find the challenges to engaging in engineering education research formidable. Perceptions of what constitutes scholarly activity in the face of promotion and tenure keep many talented and passionate engineering faculty from working in this field. However,(More)
Three successful historical reforms of chemical engineering education were the triumph of chemical engineering over industrial chemistry, the engineering science revolution, and Engineering Criteria 2000. Current attempts to change teaching methods have relied heavily on dissemination of the results of engineering-education research that show superior(More)
