Spring 2011
This study was part of the development of an ice jam flood forecasting system for Hay River, NWT. 2-D numerical models were used to simulate ice processes in an effort to predict ice jam formation. A summer survey was conducted to finalize the bathymetry of the Hay River Delta. Observations were...

Acid-base properties of cyanobacterial surfaces II: Silica as a chemical stressor influencing cell surface reactivity
Download2008
Owttrim, G.W., Lalonde, S.V., Smith, D.S., Konhauser, K.O.
Bacteria grow in complex solutions where the adsorption of aqueous species and nucleation of mineral phases on the cell surface may interfere with membrane-dependent homeostatic functions. While previous investigations have provided evidence that bacteria may alter their surface chemical...

Lake and sea ice and their snow covers are major components of Earthâs cryosphere and act to strongly modify climatic and biological systems. Both ice types serve as an important habitat for micro-fauna and support macro-fauna and strongly modify the exchange of energy, gases, and momentum...

Atomic Force Microscopy Characterization of Hydrogen Terminated Silicon (100) 2x1 Reconstruction
DownloadFall 2015
Non-contact Atomic Force Microscopy (NC-AFM) is a Scanning Probe Microscopy tool offering unique non-perturbative analysis of surfaces and adsorbates at the atomic scale. AFM precisely oscillates a sharp tip above a sample. By monitoring the shift in resonance frequency of a quartz tuning fork...

High aspect ratio microelectromechanical structures have been found, in the literature, to collapse due to capillary forces of liquids. In this dissertation, mathematical models are developed to study (i) the collapse of a microstructure represented by a double cantilevered beam (DCB) with a free...

This dissertation investigates the influence of surface heterogeneities on colloid deposition. First, deposition of colloidal particles on a nanofiltration membrane during cross flow membrane filtration was studied under different operating pressures and solution chemistries. An atomic force...

Competitive Analysis and Value Proposition of Frozen Silt Mats as an alternative to Crane Timber Mats
DownloadFall 2018
The construction industry is adopting the modular construction paradigm with the integration of heavy crane usage. Because of the weight of the modules that are to be lifted, which currently can reach as much as hundreds of tons, ensuring proper ground integrity under the lifting equipment is...
