Hahn, Tobias; Huuk, Thiemo; Heuveline, Vincent; Hubbuch, Ju¨rgen – Journal of Chemical Education, 2015
Industrial purification of biomolecules is commonly based on a sequence of chromatographic processes, which are adapted slightly to new target components, as the time to market is crucial. To improve time and material efficiency, modeling is increasingly used to determine optimal operating conditions, thus providing new challenges for current and…

Marrero, Meghan E.; Lam, Keira – Science Teacher, 2014
Studies show that overall seafood consumption in the United States is rising (Agriculture and Agri-Food Canada 2012). Other research estimates that as much as 40% of the seafood caught worldwide is discarded, while countless sharks, whales, dolphins, birds, sea turtles, and other animals are unintentionally killed or injured by fishing gear…

Cuperman, Dan; Verner, Igor M. – International Journal of Technology and Design Education, 2013
This paper considers an approach to studying issues in technology and science, which integrates design and inquiry activities towards creating and exploring technological models of scientific phenomena. We implemented this approach in a context where the learner inquires into a biological phenomenon and develops its representation in the form of a…

Suvannatsiri, Ratchasak; Santichaianant, Kitidech; Murphy, Elizabeth – European Journal of Engineering Education, 2015
This paper reports on a project in which students designed, constructed and tested a model of an existing early warning system with simulation of debris flow in a context of a landslide. Students also assessed rural community members' knowledge of this system and subsequently taught them to estimate the time needed for evacuation of the community…

Parametric Optimization of Some Critical Operating System Functions--An Alternative Approach to the Study of Operating Systems Design
Peer reviewed Peer reviewed
Direct linkDirect link
Sobh, Tarek M.; Tibrewal, Abhilasha – Journal of STEM Education: Innovations and Research, 2006
Operating systems theory primarily concentrates on the optimal use of computing resources. This paper presents an alternative approach to teaching and studying operating systems design and concepts by way of parametrically optimizing critical operating system functions. Detailed examples of two critical operating systems functions using the…
