Paleontology is a multi-faceted subject that involves taxonomy and community analysis as two of its cornerstones. Both qualitative and quantitative approaches have been incorporated into the various methods employed in such analyses. Each paleontologist obvious has his or her own preference that...

Serpe, Michael J., Gao, Yongfeng, Zhang, Qiang M., Ahiabu, Andrews
A series of pyridine-functionalized poly (N-isopropylacrylamide)- based microgels were synthesized. Subsequently, a structured photonic device was fabricated by sandwiching the microgels between two thin Au layers, and their response to CO2 investigated. We show that devices show an optical...

Fall 2009
The extraction of bitumen (heavy oil) from the oil sands is predominantly achieved through a water-based technology. This involves a slurrying process, typically called conditioning, which is categorized into three equally important steps: bitumen-sand liberation, bitumen coalescence, and...

Effect of Pairing Status on Use of Space by Territorial Willow Ptarmigan (Lagopus lagopus): Bachelor Males Choose Life on the Edge
Download2003
Hannon, Susan, J., Eason, Perri K.
One function of territorial defense may be to facilitate mate guarding by resident males. To assess the importance of mate guarding in territoriality, we examined the spatial pattern of intrusions by male Willow Ptarmigan(Lagopusla gopus) on the territories of other males and we compared use of...

Electrocoalescence of Water Droplets in Oil Emulsions: Effect of Electric Fields, Surfactants, and Chemical Demulsifiers
DownloadSpring 2019
Stabilization of water-in-oil droplets during bitumen extraction and refining process poses a major challenge in the oil sands industry. These crude oil emulsions are stabilized by rigid films at water droplet-oil interfaces. The salty water remaining in oil causes equipment corrosion, catalyst...

Fecal Pellet Counts as a Technique for Monitoring an Alpine-Dwelling Social Rodent, the Hoary Marmot (Marmota caligata)
Download2004
Karels, T. J., Koppel, L., Hik, D. S.
We evaluated fecal pellet counts as an index of hoary marmot (Marmota caligata) social group size in order to develop a simple, inexpensive method for monitoring population change of a widely distributed, but poorly studied alpine mammal. Fecal pellet counts were conducted in three separate...
