Clubroot, caused by Plasmodiophora brassicae Woronin, is one of the most important diseases of canola (Brassica napus L.) in western Canada. While the disease is managed most effectively by planting clubroot resistant (CR) canola cultivars, genetic resistance has been overcome in more than 200...

Tan spot is a destructive foliar disease of wheat caused by the fungus Pyrenophora tritici-repentis (Ptr). Eight races (race 1 to race 8) of Ptr have been identified globally, based on their ability to produce different combinations of three necrotrophic effectors (NE): Ptr ToxA, Ptr ToxB, and...

This thesis examines the pathophysiology of asthma, attempts to determine the cellular mechanisms behind viral-induced immune memory mediated asthma exacerbations, and investigates urinary metabolomic biomarkers of asthma and neonatal hypoxia.

Visbreaking is described as a mild thermal cracking, low conversion process, which industrially operates in the temperature range of 430 to 490 °C. Conversion is limited by the onset of coke formation. The main objective of visbreaking in conventional oil refineries is to reduce the viscosity of...

The focus of this thesis is on electro-osmotically pumped flow of viscoelastic fluids through microchannels. Fluid transport in microscaled structures is typically laminar due to the low Reynolds numbers involved. However, it is known that viscoelastic polymeric liquids can display striking...

In the year 1693, the Franco-Italian astronomer Giovanni Domenico Cassini publishedthree empirical laws describing the orbital and rotational motions of the Moon. Cassini’sThird Law describes the orientations of the lunar equatorial plane and the lunar orbital planevis-a-vis the ecliptic....

This thesis work concerns the viscous fingering instability occurring during immiscible fluid-fluid displacement experiments using a novel radially-tapered fluidic cell. We use modified Hele-Shaw cells where a negative depth gradient is introduced by tapering the upper plate, so that the gap...
