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...

Evaluation of Mask and Mask Material Suitability for COVID-19 Transmission Protection and Influence of Face Velocity and Exhaled Breath Condensate on Filtration Efficiency
DownloadSpring 2022
Facemask use has been a key public health measure in response to the SARS CoV-2 pandemic; they are used to reduce airborne transmission of the disease amongst the public. The facemasks used by the public are non-medical in nature and therefore are not regulated like medical masks. Cloth masks,...

Implementation and Evaluation of Spatiotemporal Prediction Algorithms and Prediction of Spatially Distributed Greenhouse Gas Inventories
DownloadFall 2011
Growing environmental concerns require monitoring and modelling of greenhouse gases. These modelling efforts require processing of massive datasets in a timely fashion. This, in turn, can lead to feasibility problems when estimating values of missing data points. This thesis examines and compares...

Improving Measurements of the Mixing State and Mass Concentration of Particulate Emissions from Aircraft Engines
DownloadSpring 2016
This research is focused towards improving techniques used to measure particulate emissions from aircraft engines, on two fronts: first, to characterize and quantify the mixing state of particulate emissions; and second, to calibrate black carbon mass instruments with a traceable mass...

The centrifugal particle mass analyzer (CPMA)-electrometer system has been proposed as an alternative method of calibration for devices that measure black carbon. This system is proposed to replace the current calibration standard of NIOSH 5040. The repeatability and intermediate precision of the...
