Air-core microcavities and metal-dielectric filters - building blocks for optofluidic microsystems
DownloadFall 2012
This thesis describes a study on two optical devices intended to be building blocks for the creation of integrated optical/microfluidic lab-on-a-chip systems. First, arrays of curved-mirror dome-shaped microcavities were fabricated by buckling self-assembly of a-Si/SiO2 multilayers. This novel...

Air-Void Characteristics and Permeability of Fibre Reinforced Repair Mortar for Conservation
DownloadSpring 2019
Masonry is among the oldest and widespread construction materials, used to build structures traditionally, both in North America, and worldwide as well. Most of the historical buildings have been built with pre-Portland cement mortar. A large number of existing masonry buildings in Canada have...

Airborne particulate matter and a western style diet as potential environmental factors in the pathogenesis of Inflammatory Bowel Disease
DownloadFall 2012
Inflammatory bowel disease is believed to occure in response to environmental factors resulting in immune dysregulation in genetically predisposed individuals. Such environmental factors include diet, (specifically a “western diet”rich in refined sugars, and fat) and airborne particulate matter...

Airborne radar-sounding investigations of the firn layer and subglacial environment of Devon Ice Cap, Nunavut, Canada
DownloadSpring 2019
Airborne radio-echo sounding (RES) is a powerful tool to derive properties of glaciers and ice caps over spatially extensive areas, and has fundamentally improved our understanding of the distribution and structure of near-surface snow and firn, the ice thickness distribution and englacial...
