Fall 2012
The kinetics of vapor phase cracking of bitumen derived heavy gas oil and the quality of liquid products were investigated at temperatures of 600-700 °C. Fixed and condensed gases were analyzed by gas chromatography. The quality of liquid products was characterized using simulated distillation,...

Vapour-Liquid Equilibrium of by-Products n-Alcohols and 1,3-Propanediol from Polyol Production
DownloadSpring 2013
A new method for collecting vapour-liquid equilibrium data for binary mixtures is proposed in this work. A modified differential scanning calorimetry technique was used by evaluating the sample temperature instead of the heat flow. This method was tested on three well known systems and the...

Spring 2019
Ostrich eggshell (OES) beads are the first kind of ornaments in human history to be mass-produced, and they exhibit variations that simulate cultural boundaries. Previous research into the stylistic variation of OES beads identified the importance of bead diameter in assemblages from southern...

Variability in Summer Anticyclonic Activity over the Canadian Arctic Archipelago and west Greenland in the late 20th/early 21st centuries, and its impact on the firn stratigraphy of the Devon Ice Cap
DownloadFall 2013
Significant summer warming over the Canadian Arctic Archipelago (CAA) is linked to a doubling in the frequency of anticyclonic circulation over the region since 2007. The frequency of positive anomalies in summer 500 hPa geopotential height is related to Arctic sea ice volume/thickness in April,...
