Review of Maxillary expansion appliance activation methods: engineering and clinical perspectives
Download2010
Lagravère, Manuel O., Carey, Jason P., Romanyk, Dan L., Major, Paul W., Toogood, Roger W.
Objective. Review the reported activation methods of maxillary expansion devices for midpalatal suture separation from an engineering perspective and suggest areas of improvement. Materials and Methods. A literature search of Scopus and PubMed was used to determine current expansion methods. A...

Investigation into the effects of stainless steel ligature ties on the mechanical characteristics of conventional and self-ligated brackets subjected to torque
Download2014
Heo, Giseon, Nobes, David S., Al Fakir, Hussam, Major, Paul W., Melenka, Garrett W., Carey, Jason P.
Objective: Torque is applied to orthodontic brackets in order to alter the buccal-lingual angulation of a tooth. One factor that can affect torque is the ligation mode used to retain the archwire in the bracket slot. The objective of this study was to investigate the effects of stainless steel...

A new ductility exhaustion model for high temperature low cycle fatigue life prediction of turbine disk alloys
Download2011
Zhu, Shun-Peng, Sun, Rui, Zuo, Ming J., Li, Haiqing, Huang, Hong-Zhong
Based on ductility exhaustion theory and the generalized energy-based damage parameter, a new viscosity-based life prediction model is introduced to account for the mean strain/stress effects in the low cycle fatigue regime. The loading waveform parameters and cyclic hardening effects are also...

Micromechanisms Associated with the Dynamic Compressive Failure of Hot-Pressed Boron Carbide
Download2015
Ramesh, K.T., Farbaniec, Lukasz, Hogan, James
Brittle failure in boron carbide has been studied in dynamic uniaxial compression using a Kolsky bar technique. A detailed study of fragments was performed using SEM-EDS, to identify the mechanisms responsible for failure. Microstructural characterization and fracture surface observations...

Singh, Shikhar, Kumar, Amit, Jain, Siddharth
The production of biofuels (e.g., ethanol and biodiesel) requires a significant amount of water during feedstock production, transportation, and its conversion into biofuels. Therefore present study devoted to study the impact of biofuel production on water demand in Alberta. In scenario #1, it...

Marleau, L. J., Sutherland B.R., Flynn, M.R.
Bottom propagating gravity currents resulting from full- and partial-depth lock-release experiments are investigated as they approach and then propagate up a rising slope. Consistent with the prediction of a WKB-like theory, the gravity current front decelerates in a nearly uniform manner along...

The Effect on Elastic Modulus of Rigid-Matrix Tubular Composite Braid Radius and Braid Angle Change Under Tensile Loading
Download2013
Melenka, Garrett W., Leung, Cheequn K., Nobes, David S., Carey, Jason P.
The objective of this paper is to assess changes in braid radius and braid angle of braided composite tubes under tensile loading using stereomicroscope digital image correlation (DIC) based optical measurement techniques. Using this approach, displacement fields were calculated and three...

Dynamic Fragmentation of Planetary Materials: Sup-Hypervelocity Ejecta Measurements and Velocity Scaling during Impact Testing
Download2013
Hogan, James, Vincent, Gregory, Spray, John, Rogers, Robert, Schneider, Markus
Ejecta velocity measurements were made during impacts into solid planetary materials. Ejecta velocity fields overlie each other when normalized by vmax, v50%mass, and v50%KE; these correspond to the maximum velocity and median values of mass and kinetic energy among ejecta velocities....

Ullah, Mohammad, Bell, Jeff, Vaezi, Mahdi, Kumar, Amit
Alberta’s food processing industry is the second largest food waste producer after the household sector. Most of the waste currently produced from the food processing industry is landfilled. Decomposing landfill waste, moreover, emits greenhouse gases (GHG), which contribute to global warming. In...
