Gentle interruptions: transformative approaches to clinical teaching (2007)

McAllister, M, Tower, M, Walker, R

This conceptual article, drawn from the authors’ shared teaching experiences and recent student and clinician evaluation data, set out to reveal and then address some common problems faced by...

Vertical Drain Consolidation with Parabolic Distribution of Permeability in Smear Zone (2006)

Walker, R., Indraratna, B.

A vertical drain radial consolidation equation based on a parabolic reduction in permeability toward the drain is presented. The proposed equation, based on Hansbo's equal strain theory, is compared...

Organic farming - stewardship for food security, food quality, environment and nature conservation (2006)

Schnug, E, Haneklaus, S, Rahmann, G, Walker, R

Conventional agriculture is associated with problems such as pesticide residues in soils and plants, contamination of meat with antibiotics and hormones, and eutrophication of water bodies. An...

Introducing ``Conversational'' e-Learning to Management Education: A Comparison of Student Experiences From Two MIS Courses (2002)

R. Walker, W. Baets

This paper draws on the experiences of management education students following courses using a combination of e-learning and class-based learning methods at Nyenrode University. Evidence is taken...

Bu-Abbas, A., Clifford, M.N., Walker, R., Ioannides, C.

Rats were exposed to freshly prepared aqueous extracts of green tea (2.5%w/v) as the sole source of drinking water for 4 weeks. Hepatic cytochrome P450 activity was determined using chemical probes,...

Marked antimutagenic potential of aqueous green tea extracts: mechanism of action (1994)

Bu-Abbas, A., Clifford, M.N., Walker, R., Ioannides, C.

In the present study aqueous extracts of green tea, at the concentrations customarily consumed by humans, were evaluated for their antimutagenic activity against major classes of dietary and...
