Fresh Vegetable Harvesting ... 7
John Inman, who has been involved in California fresh vegetable harvesting for many decades, chronicles recent mechanized changes. With fresh-cut vegetables prevalent on grocery shopping lists and food safety a priority for quality-hungry consumers, harvesting techniques and practices have dramatically changed to meet the increasing demand for prepackaged salads and ready-to-use veggies.

Student-Centered Learning Activities ... 9
The success of a student's education may well hinge on integrating and expanding the use of diverse student-centered learning activities: portfolios, interdisciplinary team projects, problem-based learning, service-learning, and journal writing, to name only a few. Allen Zimmerman, Marybeth Lima, and Ann Christy detail innovative techniques used by proactive engineering educators.

Water-in-Oil-in-Water Double Emulsions ... 11
Louise Braud Lawson recaps recent, intriguing research done in Tulane University's Chemical Engineering Department on W₁/O/W₂ double emulsion, a continuous aqueous phase in which oil globules are dispersed. Targeted drug-delivery performance may be effected by the outcome.

Tracking Chick Locomotion ... 13
Just how much room does a chick need to be "happy"? Graduate students Kelly Persyn and Hong Li with undergrad Cary Lane experiment with cage size, keeping design, feeder space, egg productivity, and fearfulness/mortality rate under investigation. Bird welfare standards and egg production numbers are at the core of and drive their study.
