« The women folk often helped »: La conception inéquitable de la citoyenneté dans les manuels d’études sociales albertains de la première moitié du 20e siècle
DownloadFall 2022
The teaching of Canadian history has been a source of contention over the past century, particularly regarding the place of minorities in the nation’s narrative and cultural identity. In early 20th-century Alberta, history education was driven by male-authored textbooks which were used to...

On 23 November 2012, a sudden dropout of the relativistic electron flux was observed after an interplanetary shock arrival. The dropout peaks at ∼1 MeV and more than 80% of the electrons disappeared from the drift shell. Van Allen twin Probes observed a sharp electron flux dropout with clear...

Experimental Investigation of Near-well Fluid Mechanics on the Scaling Mechanism in Narrow Rectangular Slots
DownloadSpring 2020
This experimental study investigates the effect of near-well fluid mechanics on the scaling failure mechanism specific to SAGD production well. The scaling failure mechanism can be triggered by the pressure drop phenomenon and causes the plugging of the slots in the oilfields. The scale formation...

The current work presents the results of an experimental study on the effects of submergence on the performance of a submerged hydraulic jump with baffle blocks downstream of a sluice gate. A wide range of Froude numbers, submergence factors, and block sizes, locations and arrangements were...

Significant populations of electrons with energies of tens of keV appear in the Earth's inner central plasma sheet during the substorm expansion phase. Increasing observational evidence indicates that these injections begin at a radially narrow but azimuthally extended transition between very...

A two-dimensional numerical model of low-altitude auroral flux tubes has been developed for simulation of coupling between the magnetosphere and the ionosphere. The model considers a realistic ionosphere with multiple ion and neutral species, collisions, cooling and heating processes, as well as...
