Application of Variable Speed Drives for Improved Grinding Energy Efficiency

The research program is aimed at developing operating systems that enable grinding mill speeds to be controlled in responses to variations in ore properties. Although there are studies that show speed control can improve productivity and significantly reduce energy requirements, mines presently used fixed speed systems for their ball and tower mills. With development of new variable speed drive systems that can retrofitted to the fixed speed systems, there is an opportunity for mines to introduce the technology for their operation.

Passive optical remote sensing of channel bathymetry for monitoring of large river morphodynamics

Air photos and satellite images offer a comprehensive perspective on rivers that can be useful for the study and management of aquatic ecosystems. In particular, water depths can be determined remotely by relating image properties (color, brightness, etc.) to depths measured through fieldwork. However, this reliance on field data for calibration of the depth/image relationship requires costly, sometimes dangerous fieldwork and means the methods cannot be applied to data sources without associated field-measured depths.

Enteroids and enteroid derived monolayer cultures: Using primary intestinal epithelial cell cultures to define the mechanisms underlying epithelial intrinsic innate defenses

Using growth media available from Stemcell technologies, along with our own tools and techniques, we can isolate and grow intestinal stem cells from mice or human patient donors into enteroid cultures. Enteroids are 3D cell cultures that replicate many of the structures and types of cells found in the intestinal lining. We propose to work with Stemcell technologies to continue to develop their growth media for enteroid culture and apply these new media and techniques to further or understanding of how these cells help the body defend against infection.

University-to-Work Transition Project

Research on university graduates’ University-to-Work transition (UWT) is sharply polarized between two discourses: the smooth transition narrative and the crisis narrative. Proponents of the smooth transition narrative such as universities are reporting high-rates of student satisfaction, skill transferability as well as early-career earnings consistent with those of 1970s and 1980s’s graduates. At the same, the crisis narrative is pointing at rampant underemployment, a loose School-to-Work transition structure and a blunt lack of high-skilled technical labour.

Optimization and validation of carbon nanofiber catalyst supports in fuel cell stack

Motivated by the urgent need for clean and sustainable source of energy we propose to develop structurally and chemically controllable fuel cell catalyst layers based on ultrafine nanocomposite carbon fibre catalyst support. Manufacturing parameters will be controlled and optimized to investigate the effect of microstructure on key performance factors. Ultimately, the knowledge gained from this study will pave the way to building more efficient fuel cells. Current phase of the project involves validating our design by in-situ testing.

Exploratory study: modification of sludge based sorbents for nutrient removal from stormwater runoff

Nutrients (P, N) in stormwater runoff are a major cause for eutrophication and algae blooms. Kerr Wood Leidal (KWL) is a leader in proving progressive solutions for stormwater management in BC, is seeking to improve the rain garden system to effectively capture the nutrients in the runoff. The proposed project will investigate various chemical activation to produce effective biomass-/sludge-based sorbent.

Kinetics of dispersion of fine phosphate particles associated with organic matter

This research project seeks to improve the process which is used to recover fine phosphorous particles from mine tailings. Phosphorus based fertilizers are important for plant growth and essential to large-scale, high-efficiency farming methods. However, the processing method used to obtain phosphate from phosphate-bearing ore is not very efficient. Upward of 13 % of the available phosphate is lost to the waste stream during processing, which represents a major inefficiency and creates a large environmental problem.

Social and informational strategies for reducing electricity and natural gas consumption in multi-unit residential buildings

The proposed research will attempt to help residents reduce energy use in apartment buildings. The intern will provide residents with energy use feedback that shows their building’s energy use compared to a neighboring building. Buildings that reduce energy use will receive encouragement to continue conserving. The intern will work with two partnering utilities companies, FortisBC and BC Hydro. These partners will help provide energy use data for each building during the project.

Designing multi-family housing to boost social capital and psychological well-being

There is no more powerful correlate of human health and wellbeing than positive social relationships. Multi-family housing, through design, layout, and location, can exert a significant effect on local relationships, neighborhood trust and residents’ sense of belonging. We propose a program to gather, refine and illustrate the evidence linking design and social wellbeing in multi-family housing.

Evaluation of cyanide and thiosulphate lixiviant systems for KSM Seabridge gold circuit

Most of the gold that is produced by hydrometallurgical processes is recovered by cyanide leaching. However, the reactive nature of some minerals questions the applicability of cyanide technology for selected applications. The current research is designed to evaluate the cyanide technology as well as an alternative processing path for a particular material through extensive experimental program. The project will yield the mathematical models describing all chemical processes in each circuit, as well as mass and energy balances based on laboratory data and scientific reasoning.
