DownloadSpring 2015
This thesis presents the formulation of geo-mechanical design parameters using a combination of laboratory and insitu test results in the heavily overconsolidated cohesive till formation in the city of Edmonton. These data were then used in the design of the recently constructed North LRT twin...

Yolk sac infections in broiler chicks: studies on Escherichia coli, chick acquired immunity, and barn microbiology
DownloadFall 2011
The avian yolk sac is a well vascularised membrane that surrounds the yolk of an embryonated egg and functions as a placenta-like structure transferring yolk nutrients including maternal antibodies, to the embryo. The absorption of the yolk sac content during the first days post-hatching is...

You Can Ride Too! An Exploration of the Guided Discovery of Two-wheeled Cycling Skills by Youth with Intellectual Disabilities
DownloadFall 2014
Learning to ride a bike is an important milestone in the life of a child, yet many children with disabilities never have the opportunity to experience this success. Few studies have examined how to teach this skill to individuals with intellectual disabilities, with techniques that do not use...
