An examination of laptop-based off-task behaviours in secondary school classrooms
(2016-01-01)
The purpose of this study was to examine factors that affect secondary school students’ off-task behaviours in laptop-based classrooms. Quantitative and qualitative data were collected from 224 secondary school students ...
Elder perspectives: leveraging digital tools in language revival initiatives
(2019-12-01)
Elders are held in high regard in First Nations, Metis, and Inuit (FNMI) communities. They are the intergenerational transmitters of ancestral language and Indigenous knowledge. Without language revival initiatives, ancestral ...
Examining the affordances and constraints of using infographics in pre-service teacher education
(2018-04-13)
Infographics are a communication tool that can be used to share large amounts of data in a more aesthetically pleasing and understandable way. The production and consumption of infographics encourages students to develop ...
Conceptual design of a thermal hydraulic loop for multiple test geometries at supercritical conditions named supercritical phenomena experimental test apparatus (SPETA)
(2012-04-01)
The efficiency of nuclear reactors can be improved by increasing the operating pressure of current nuclear reactors. Current CANDU-type nuclear reactors use heavy water as coolant at an outlet pressure of up to 11.5 MPa. ...
Study on linking a SuperCritical water-cooled nuclear reactor to a hydrogen production facility
(2011-07-01)
The SuperCritical Water-cooled nuclear Reactor (SCWR) is one of six Generation-IV nuclear-reactor concepts currently being designed. It will operate at pressures of 25 MPa and temperatures up to 625°C. These operating ...
Thermal aspects of high efficiency channel with conventional and alternative fuels in SuperCritical water-cooled reactor (SCWR) applications
(2011-03-01)
Chosen as one of six Generation‒IV nuclear-reactor concepts, SuperCritical Water-cooled Reactors (SCWRs) are expected to have high thermal efficiencies within the range of 45 ‒ 50% owing to reactor‘s high outlet temperatures. ...
Heat-transfer analysis of double-pipe heat exchangers for indirect-cycle SCW NPP
(2012-04-01)
SuperCritical-Water-cooled Reactors (SCWRs) are being developed as one of the Generation-IV nuclear-reactor concepts. SuperCritical Water (SCW) Nuclear Power Plants (NPPs) are expected to have much higher operating parameters ...
Sensitivity analysis of fuel centerline temperatures in SuperCritical water-cooled reactors (SCWRs)
(2012-12-01)
SuperCritical Water-cooled Reactors (SCWRs) are one of the six nuclear-reactor concepts currently being developed under the Generation-IV International Forum (GIF). A main advantage of SCW Nuclear Power Plants (NPPs) is ...
Study of heat transfer in a 7-element bundle cooled with the upward flow of supercritical Freon-12
(2012-04-01)
Experimental data on SuperCritical-Water (SCW) cooled bundles are very limited. Major problems with performing such experiments are: 1) small number of operating SCW experimental setups and 2) difficulties in testing and ...
An experimental study of the relative response of plastic scintillators to photons and beta particles within the context of tritium monitoring
(2011-08-01)
A scintillation counting system has been constructed with the use of BC-400 and EJ-212 series plastic scintillators along with a subminiature photomultiplier tube to investigate the effect of increasing plastic scintillator ...
