Fall 2012
Glancing angle deposition (GLAD) is a physical vapour deposition (PVD) technique capable of fabricating highly porous thin films with controllable film morphology on the 10 nm length scale. The GLAD process is flexible and may be used on virtually any PVD-compatible material. This makes GLAD a...

Changes in peatland plant community composition and stand structure due to road induced flooding and desiccation
DownloadFall 2017
Roads built through peatlands with horizontal water flow can to act as dams that affect local hydrology and thus vegetation composition and structure. On the ‘upstream’ side of roads, soils can become waterlogged causing either increased tree mortality, or stunted tree growth; conversely, the...

Characterization of Aerosol Deposition in Children and Infants Using Idealized Extrathoracic Geometries
DownloadFall 2014
This thesis describes a number of experimental studies performed with the common goal of characterizing pharmaceutical aerosol deposition in children and infants using idealized extrathoracic geometries. First, an in vitro study of the recently proposed Alberta Idealized Child Throat showed that...

Spring 2015
Colloidal-collector interactions are of fundamental importance in separation and filtration technologies. Here, the effect of collector grains on the behavior of colloidal particles was studied in two different experimental systems, i.e., column studies with stationary collectors and batch mixing...

Consequences of peatland disturbance for dissolved organic matter and nutrient transport and fate in northern catchments
DownloadFall 2023
Northern peatlands contain ~415 Pg of carbon (C) in soil organic matter and are significant sources of dissolved organic matter (DOM) in inland waters. DOM includes a range of molecules that are C-rich and may also contain nitrogen (N) and phosphorus (P). The escalating disturbance of peatlands...

Development of Empirical Models to Predict Deposition of Aerosols in the Extrathoracic Airways of Children
DownloadSpring 2012
The experimental studies described in this thesis were performed with the goal of measuring deposition of aerosols, inhaled either nasally or orally, in the extrathoracic airways of children in different age groups. We pursued in vitro methods and characterized the deposition of aerosols in the...

Welz, M., Faulkner, S.G., Tonn, W.M., Schmitt, D.R.
Industrial development, including geophysical exploration and mining, has increased use of explosives in and near fish habitat. To protect fish and their incubating eggs, Canadian blasting guidelines contain maximum allowable limits for overpressure and peak particle velocity (PPV). Although many...

Effects of long-term nitrogen and sulfur deposition on soil microbial communities and soil properties in the Athabasca oil sands region in northern Alberta, Canada
DownloadFall 2016
Intensified oil sands activities have resulted in elevated levels of nitrogen (N) and sulfur (S) deposition in the mixedwood boreal forest in the Athabasca oil sands region (AOSR) of northern Alberta, Canada. The deposition of N and S can affect the surrounding ecosystem and it is important to...

Examination of Wet Meadow Creation as a Restoration Option for Extracted Peatland Sites in Alberta
DownloadSpring 2014
Question: Can a wet meadow plant community be established on abandoned peatlands through broadcast plant diaspore spreading in western Canada? Does fertilization impact the development and establishment of the wet meadow? Location: Evansburg, Alberta, Canada Methods: Wet meadow vascular and...

Factors influencing size inequality in peatland black spruce and tamarack: Evidence from post-drainage release growth
Download1999
1 We used tree ring analysis to determine stem radius and thus examine size variation over time in two even-aged (approximately 40-year-old) mixed populations of black spruce and tamarack established on peatlands in a boreal forest. We also followed the response of one of these populations to...
