Fall 2017
Water contamination by ammonium ions presents huge risks to the ecosystems. This work evaluated the potential application of digested sludge pyrolyzed biochar on ammonium removal. Anaerobic digester sludge was collected from a municipal wastewater treatment plant in Alberta, Canada and pyrolyzed...

Carbon Dynamics across Contrasting Temperate Agroecosystems: Soil Organic Matter Pools, Mycorrhizae, Water Use-efficiency, Methane and Carbon Dioxide Fluxes
DownloadSpring 2022
Perennial grain crops have been proposed as a sustainable alternative to conventional annual grain crops, since they potentially hold multiple desirable features including increased soil C sequestration and biodiversity, mitigation of greenhouse gases (GHGs), and reduction of water loss and...

Effect of Biochar on Soil Microbial Communities, Nutrient Availability, and Greenhouse Gases in Short Rotation Coppice Systems of Central Alberta
DownloadFall 2015
Short rotation coppice (SRC) systems using willow (Salix spp.) grown on marginal soil, amended with biochar may represent a promising source of renewable green energy for rural communities of Alberta. The Ohaton Wood Energy project, an agroforestry site located in Camrose County, is one of...

Perkins, S., Zuidhof, Martin J., Feddes, John J. R., Robinson, Frank E.
Four environmental chambers housing either 75 (5.5 birds/m\") or 37 turkeys (2.8 birds/m ) were used to study the impact of stocking density on air quality, bird health, and performance under similar per bird ventilation rates (3 L/s per bird). Stocking density had little effect on air quality or...

Fall 2017
This thesis focuses on formulating and analyzing non linear models for microbial dynamics vis-a-vis human and environmental health. Firstly, we develop and investigate a stoichiometric organic matter decomposition model in a chemostat culture that incorporates the dynamics of grazers. This...

Spring 2014
Fugitive emissions of methane (CH4) and carbon dioxide (CO2) from a lagoon containing biosolids were continuously measured using an eddy covariance system for three months. Open Path Fourier Transform Infrared Spectrometry (OP-FTIR) was also used to quantify concentrations of methane and ammonia...

Respiration, Acid/Base, Ammonia and Ionoregulatory Strategies in the Pacific hagfish (Eptatretus stoutii)
DownloadFall 2016
Hagfish feed on putrefied carrion, which poses several environmental challenges to the scavenger including hypoxia (Low PO2), hypercapnia (high PCO2) and high environmental ammonia (HEA). To any other organism, these conditions would be physiologically challenging; however, hagfish seem to have...

Techno-economic feasibility of hybrid energy systems for small-scale space heating applications in Canada
DownloadSpring 2021
Given the large energy consumption for space heating demands in Canada, renewable energy heating systems are becoming increasingly more popular and more important for small scale applications. However, these face tough challenges for applicability in cold climate regions due to various physical...
