Hydrological impacts of wildfire and climate change on sediment and organic carbon loads at the watershed scale
DownloadFall 2019
Climate change, extreme weather events, and disturbances such as wildfires alter hydrology, which in turn influences the cycling of water quality constituents such as sediments and nutrients. Organic carbon (OC) is an important element affecting water quality, as it can transport heavy metals,...

Interactions among Nitrogen Input, Nitrification Inhibition, Edaphic and Environmental Conditions on N2O Fluxes and associated Biological Processes in Central Alberta Soils
DownloadFall 2020
Increasing atmospheric concentration of nitrous oxide (N2O) emissions due to intensified human activities is of concern, as N2O is not only a precursor for stratospheric ozone destruction but also an important greenhouse gas. Agriculture accounted for about 82% of the anthropogenic N2O production...

Observations of Snow and Ice Formation on Solar Photovoltaic Panels and an Enhanced Method of Modelling Snow Melting from Solar Photovoltaic Panels
DownloadSpring 2019
One of the fundamental limitations of solar photovoltaic (PV) generating systems in cold regions is snow accumulations blocking irradiance from reaching the PV cells. Snow accumulations on PV panels result in both reduced electricity generation and increased uncertainty in electricity generation...

ON THE ABILITY OF PROTECTIVE HEADGEAR TO ALTER SKULL AND BRAIN KINETICS DURING BLAST AND IMPACT: AN EXPERIMENTAL STUDY USING A SURROGATE MODEL OF THE HUMAN HEAD WITH NOVEL INSTRUMENTATION
DownloadSpring 2019
Blast-induced traumatic brain injury (bTBI) has become increasingly prevalent among military personnel over recent years. Head protection is fielded to mitigate the amount of energy imparted to head, as a result of ballistic and impact exposure. Despite the efficacy of contemporary headgear in...

Simplified seismic design methods for low-ductile steel multi-tiered concentrically braced frames
DownloadFall 2020
Multi-Tiered Concentrically Braced Frames (MT-CBFs) represent a bracing configuration where two or more concentric braced panels are stacked between the storey levels in multi-storey buildings or between the ground and roof levels in single-storey buildings such as sports facilities, airplane...

Fall 2024
Phosphogypsum (PG) is a by-product of phosphorus fertilizer production and is piled into large stacks that eventually require reclamation. The first step in the reclamation process is constructing a topsoil cap to facilitate revegetation. An alternative to traditional topsoil caps underlain with...
