Gestational weight gain, physical activity, and nutrition counselling practices of prenatal health care providers: What influences practice?
DownloadFall 2016
Appropriate gestational weight gain is important for maternal and child health. Data from a recent Alberta cohort showed 49% of pregnant women gained weight in excess of Health Canada guidelines. Regional studies have shown low rates of gestational weight gain counselling by health care...

Metallic thin films for NEMS/MEMS: from fundamental behaviour to microstructural design and fabrication
DownloadFall 2011
The main focus of this thesis is the study of thin metal films in microelectromechanical/nanoelectromechanical systems (MEMS/NEMS), ranging from application to fundamental behaviour. The use of metallic structural components is desirable since they are electrically conductive, optically reflective...

Nanophotonic detection of nanomechanical structures for use toward mass sensing applications
DownloadSpring 2014
Nanomechanical beam resonators show much promise for use in integrated on-chip mass sensing systems. This follows from their own very small masses and also their ability to store the mechanical energy of their oscillations to produce strong measurable mechanical response signals. To achieve...
