Item Open Access 10,000 Drowned: Commemorating the Caribou(Faculty of Graduate Studies and Research, University of Regina, 2020-01) Orr, Margaret Grace; Garneau, David; Streifler, Leesa; Chambers, RuthThis exhibition commemorates a caribou herd that drown during their fall migration in 1984. The disaster occurred when Hydro-Quebec opened the Caniapiscau reservoir spill gates two hundred and seventy miles upstream from Limestone Falls on the Caniapiscau River. This caused the river level to rise and send a torrent of water towards the Ungava Bay. At their traditional river crossing, thousands of caribou were swept over the falls and drowned. This paper supports my MFA graduating exhibition, 10,000 Drowned, installed in The Fifth Parallel Gallery from November 25 to December 6, 2019. 10,000 Drowned is an installation of six large oil paintings representing the land, sky, water, fire, four directions, and the migration of caribou. There are also four large ceramic vessels representing air, water, land, and fire, and one hundred ceramic antlers representing the lost caribou. In addition, a video installation shows the caribou’s point of view as they travel over the land and then drown. The exhibition is my delayed response to my anguish over this disaster. I grew up on the land situated around the Chisasibi River in Northern Quebec. Through my Cree and Inuit relatives, I absorbed a lot of knowledge about how to live with the land and animals; how to survive using only basic of tools. These teachings come from how we relate with the natural environment and with one another. This paper describes my life and community. This background is essential to understanding the meaning of the caribou and this event in our lives. Through stories and by reflecting on my research process, I hope to offer insight into how contemporary forms of Indigenous art-making continue from traditional Cree knowledge practices. I returned to the site of the drownings many times. I mapped the caribou migration territory from a bird’s-eye view. I talked to elders and others about this event. But it was only when I took this experiential research method to a deeper embodied level that I got close to the meaning of this event. Only by submerging myself in icy water, feeling what drowning was like, was I able to complete my connection with these beings.Item Open Access 3-methylimidazolium and pyridinium halide and halohydrogenate(s)(i) ionic liquids.(Faculty of Graduate Studies and Research, University of Regina, 2003) Driver, Gordon; Johnson, Keith E.Item Open Access 3D Terrain Mapping(Faculty of Applied Science and Engineering, University of Regina, 2011-04-02) Chan, Jackson; Suh, SukHyunA pilot uses a joystick to remotely control a robot in order to survey an unknown terrain. The acceleration of the robot is measured by an accelerometer mounted on the robot; the data from the accelerometer is sent to the user’s computer via Bluetooth. The computer uses this data to compute the position of the robot, and to generate a 3D map of the terrain.Item Open Access A 900 MHz short-distance ranging system.(Faculty of Graduate Studies and Research, University of Regina, 2007) Meng, LeiItem Open Access A Batalin-Vilkovisky algebra structure on the Hochschild cohomology of truncated polynomials.(Faculty of Graduate Studies and Research, University of Regina, 2007) Tian, YangItem Open Access A bench-scale investigation of land treatment of soil contaminated with diesel fuel.(Faculty of Graduate Studies and Research, University of Regina, 1998) Taylor, Chad Micheal; Viraraghavan, T.Item Open Access A biography of Chief Walter P.

The pathway utilized to assess the performance of the amine bi-blend for commercial application involved conducting carbon capture experiments in a laboratory bench-scale mini-pilot plant. This approach aimed to validate the solvent's performance under conditions that mimic a full-scale commercial industrial CO2 capture plant. The research also addresses the urgent need for more efficient and cost-effective carbon capture solutions to combat increasing greenhouse gas emissions and global warming. Experiments were conducted with varying feed gas compositions, with CO2 concentrations ranging from 4.5% to 30%, to simulate different industrial emission scenarios. Key performance metrics, including CO2 absorption efficiency, cyclic capacity, mass transfer rates, and energy consumption for solvent regeneration, were meticulously evaluated. For a CO2 partial pressure of 4.5%, the novel solvent blend demonstrated significant performance enhancements compared to 5M MEA. Specifically, the 4M (2:2) AMP:1-(2HE) PRLD blend exhibited an enhancement in absorption efficiency by up to 25% at a reboiler temperature of 110 °C, 41% at 100 °C, and over 700% at 90 °C. Additionally, there was a reduction in regeneration energy requirements by approximately 30% at 110 °C, 43% at 100 °C, and 84% at 90 °C. The novel blend showed robust performance across a wide range of these parameters, indicating its versatility and suitability for diverse industrial applications. The study also revealed an average increase of 150% in the overall gas phase volumetric mass transfer coefficient (KGav) and 110% for the overall liquid-phase volumetric mass transfer coefficient (KLav). These significant improvements emphasize the novel blend's superior mass transfer performance, which is crucial for maximizing CO2 capture efficiency and column design. Parametric studies were conducted to understand the influence of various operational parameters on mass transfer performance. It was observed that the absorption efficiency and mass transfer rates were significantly influenced by CO2 loading, gas flow rate, desorption temperature and pressure. Results from this exercise showed that there is a strong positive correlation between the reboiler temperature and the efficiency as well as the overall mass transfer coefficient. It was also noted that the mass transfer was mainly controlled by the liquid phase while increasing the desorber pressure had an inverse effect on the lean amine loading which was attributed to the higher gas solubility at the higher pressure. The effect of CO2 partial pressure was also studied and a negative correlation was observed between CO2 partial pressure and the absorber efficiency, overall gas phase mass transfer coefficient. Heat duty analysis revealed that the novel solvent blend required less energy for regeneration, thus offering a more energy-efficient solution. The specific energy consumption for the AMP-PRLD blend was found to be significantly lower than that for 5M MEA, highlighting its potential to reduce operational costs and environmental impacts. The study concludes that the novel solvent blend not only provides a more efficient CO2 capture solution but also aligns with the goals of reducing greenhouse gas emissions and achieving net-zero emissions from the indirect co-combustion of natural gas and biomass for energy generation even at relatively lower desorption temperature (100-110 °C) thus significantly contributing to energy savings.Item Open Access A comparative study of contemporary feminist issues and methods in Christianity, Islam and Hinduism.(Faculty of Graduate Studies and Research, University of Regina, 1996) Anderson, A.
