Fall 2010
A 9.4 T magnetic resonance imaging (MRI) system was used to evaluate the response of a human tumour xenograft model to radiation therapy. The apparent diffusion coefficient (ADC) and the transverse relaxation time (T2) of human glioblastoma multiforme (GBM) tumour xenografts in NIH-iii nude mice...

Addiction counselling self-efficacy, job satisfaction, motivation, and burnout: A mixed methods study
DownloadFall 2009
Addiction counsellors provide the majority of treatment to individuals struggling with substance abuse and problem gambling behaviour and, therefore, compose an essential workforce for providing effective treatment to individuals with addictive behaviours. Given the growing body of research...

Two alkyl-bridged aromatic compounds, with molecular weights of 899.70 g/mol and 1127.99 g/mol, were thermally cracked with 1-hexadecene, 1- octadecene, or trans-stilbene, in a batch microreactor at 375–430 °C for 15 to 45 min. The objective of the study was to investigate the kinetics of the...

In this thesis, we study theoretically and empirically the additive abstraction-based heuristics. First we present formal general definitions for abstractions that extend to general additive abstractions. We show that the general definition makes proofs of admissibility, consistency, and...

Additive Manufacturing and Other Techniques for Fabrication of Foams and Electrically Conductive Polymer Composites
DownloadSpring 2023
In this thesis, two aspects of advanced uses for additive manufacturing and microfabrication are investigated: stretchable electronics and polymer foams. These topics were initially part of an extended project effort to develop new capabilities in deformable, high-frequency antennas and the...

Additive Manufacturing of Shape Memory Polymers: Effects of Print Orientation and Infill Percentage on Mechanical and Shape Memory Recovery Properties
DownloadFall 2017
Material Extrusion Additive Manufacturing (MEAM), also known as Fused Deposition Modeling (FDM), is a manufacturing technique in which three-dimensional objects are built. These objects are built by repeatedly extruding thin layers of molten materials through a nozzle in different paths and...

Addressing Diameter Non-uniformity in the Melt Spinning of Asphaltenes-Derived Carbon Fibres
DownloadSpring 2023
Asphaltenes offer a cheap alternative to the predominant precursor currently used in the manufacture of carbon fibres. Melt spinning is typically employed for transforming asphaltenes into a fibrous form but faces two challenges: inconsistent or poor spinnability and a large diameter variation in...

Addressing exercise in therapy: Therapists’ personal exercise habits, attitudes, knowledge, and perceived barriers to addressing exercise with clients.
DownloadFall 2011
This study was designed to investigate the factors that contribute to addressing exercise in psychotherapy. Self-identified psychotherapists (n=94) completed surveys relating to: the frequency and type of conversations they have with clients regarding exercise; the frequency and length of time in...
