Understanding the wettability of different surfaces for the fractionation of complex lipid mixtures using supercritical carbon dioxide
DownloadSpring 2024
Santos Hernandez, Eileen Vanessa
Supercritical fluid fractionation of complex lipid mixtures has emerged as a green alternative for conventional methods. Packed columns have been used to fractionate diverse lipid mixtures using supercritical carbon dioxide (SC-CO2) under different conditions. However, there is a lack of...

Spring 2016
In this study, a two-step flocculation method by combining anionic and cationic polymeric flocculants on the treatment of oil sands tailings was investigated. Compared to conventional flocculation by using a single anionic or cationic polymer, which has been a widely exploited procedure for...

Ruminal acidosis is a persisting digestive disorder in modern ruminant production; however, the susceptibility of cows to ruminal acidosis differs among cows fed a common diet. The overall objective of this research was to evaluate factors affecting the susceptibility of cows to ruminal acidosis....

Understanding youth experiences and information needs related to online mental health searching: A qualitative descriptive study
DownloadFall 2022
Background: A study of the mental health of Canadian youth from 2011-2018 showed an increase in the prevalence of perceived poor/fair mental health (1). Yet, many youth do not access mental health services provided by a health care provider. The most common help-seeking approach among youth is an...

Understanding zinc sulfide activation mechanism and impact of calcium sulfate in sphalerite flotation
DownloadSpring 2012
Quartz crystal microbalance with dissipation (QCM-D) was used to study the zinc sulfide activation with silver, copper and lead. The interactions between calcium sulfate and minerals and gypsum nucleation on functional surfaces were investigated using a QCM-D, surface forces apparatus (SFA), and...
