Arsenic is a proven human carcinogen and associated with a myriad of other adverse health effects. This metalloid is methylated in human liver to monomethylarsonic acid (MMAV), monomethylarsonous acid (MMAIII), dimethylarsinic acid (DMAV), and dimethylarsinous acid (DMAIII) and eliminated...

In this dissertation, a hydrologic classification approach was tested using the shape factor of hydrographs to represent variation in streamflow regimes across Alberta. Hydrograph shape factor was effective at separating the forested landbase into 6 spatially distinct regions. Further statistical...

Stratford, Kevin, Williams, Richard G., Myers, Paul G.
The role of the thermohaline circulation in controlling export production, oxygenation of deep waters, and hence possible sapropel formation in the eastern Mediterranean is examined using a simple nutrient-cycling model. The model is driven by velocity fields from a general circulation model and...

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...

A high-resolution coupled ocean–sea ice model is set up within the Labrador Sea. With a horizontal resolution of 1/60◦ , this simulation is capable of resolving the multitude of eddies that transport heat and freshwater into the interior of the Labrador Sea. These fluxes strongly govern the...

Synthetic polymers are still widely used in today’s life despite all environmental issues attributed to them. Replacing synthetic polymers with natural biodegradable polymers has been considered as a way of reducing these environmental impacts partially, if not completely. Hydroxyporpyl xylan...

Relationships between variations in peak Canadian forest fire season (JJA) severity and previous winter (DJF) global sea surface temperature (SST) variations are examined for the period 1953 to 1999. Coupled modes of variability between the seasonal severity rating (SSR) index and the previous...

Microstructural and mechanical characterization of variability in porous advanced ceramics using X-ray computed tomography and digital image correlation.

Lo, Calvin, Sano, Tomoko, Hogan, James D.
This paper explores microstructural and mechanical variability in porous ceramics, combining advanced X-ray computed tomography (XCT) and digital image correlation (DIC) techniques to characterize an alumina material. The results show low variability in microstructure, with median pore size...

Minimizing invasion risk by reducing propagule pressure: a model for ballast-water exchange
Download2005-01-01
Lewis, Mark A., Wonham, Marjorie J., MacIsaac, Hugh J.
Biological invasions are a major and increasing agent of global biodiversity change. Theory and practice indicate that invasion risk can be diminished by reducing propagule pressure, or the quantity, quality, and frequency of introduced individuals. For aquatic invasions, the primary global...
