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...

GHG Emissions from Oil Sands Tailings Ponds: Overview and Modelling Based on Fermentable Substrates
Download2014-11-28
Burkus, Z., Pletcher, S., Wheler, J.
Surface mining of Alberta bitumen is probably the biggest mining operation in the world. It has a significant environmental footprint with about 840 km2 total active footprint in 2012 and 895 km2 in 2013 (Fig 1) (AESRD 2014). Of this area, tailings ponds covered 239.3 km2 in 2013...

Motamedi, Pouyan, Bosnick, ken, Cui, Kai, Cadien, Ken, Hogan, James D.
There is a great interest in various branches of the advanced materials industry for the development of novel methods (and improvements to existing ones) for the deposition of conformal ultrathin metallic films. In most of these applications, like enhanced solar absorbers and microelectronics,...

Impacts of climate change from 2000 to 2050 on wildfire activity and carbonaceous aerosol concentrations in the western United States
Download2009
Mickley, L.J., Westerling, A.L., Logan, J.A., Hudman, R.C., Flannigan, M.D., Spracklen, D.V., Yevich, R.
We investigate the impact of climate change on wildfire activity and carbonaceous aerosol concentrations in the western United States. We regress observed area burned onto observed meteorological fields and fire indices from the Canadian Fire Weather Index system and find that May-October mean...

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...

Kramer, J.R., McMahon, T.A., Denison, P.J.
An in-depth review of the literature related to deposition of gases and particulates by dry deposition and precipitation scavenging is reported. Recommendations are made on the hypotheses, algorithms or models considered to be most suitable for incorporation into a pollutant transport and...

Desai, A., Grant, R.F., Sulman, B.
Responses of wetland productivity to changes in water table depth (WTD) are controlled by complex interactions among several soil and plant processes, and hence are site-specific rather than general in nature. Hydrological controls on wetland productivity were studied by representing these...

Graphene has created much excitement in the scientific community since 2004, when Novoselov and Geim developed a method to exfoliate atomic layers from graphite, earning them the 2010 Nobel prize. The great interest in graphene stems from its outstanding material properties such as atomic...
