Current Heavy Rare Earth Element (HREE) processing techniques are expensive, environmentally-challenging, and slow. Kinetic models predict that the rate of acid permeation of a mineral is the rate controlling step. Therefore, permeation rate controls the acid quantity and residency time of the mineral in the acid bath; impacting costs. Kinetic models are based on structural assumptions including the uniform distribution of elements within a mineral. This study proposes to employ atom probe tomography on the HREE-mineral gadolinite: an ore mineral in the resource at Strange Lake, Quebec.
This project will be with Vena Medical that focused on creating a forward viewing imaging microcatheter to provide a real-time navigational perspective for interventional physicians. The Vena Microcatheter will make interventional procedures faster, easier, and safer for both patients and physicians. This project will investigate the novel polymer optical fiber with high flexibility and high-quality image transmittance for medical microcatheter.
This research will measure the effects of the Cycling Without Age program on participants by observing a variety of indicators. An existing program in a long-term care home will be observed, and 50 residents will be recruited: a biking group (n=25) who will be biked twice a week for 12 weeks and a strolls group (n=25) who will go for walks/wheelchair rides outside.
Visier Solutions Inc hopes to create a new standard for the measurement of employee diversity in organizations based on scientific research and measured baselines. With the help of the interns, this study will set a standard for the practical measurement of diversity in organizations as well as best practices in the analysis of metric results. The findings of this study will enrich our understanding of diversity and equal opportunity treatment of diverse groups in the corporate environment.
Driven by climate change induced water scarcity, further enhanced by rapid urbanization and population growth, potable water reuse initiatives are gaining interest. Potable reuse involves the indirect or direct use of highly treated municipal wastewater as a municipal drinking water source. Historically, the most commonly installed potable reuse train consisted of microfiltration, reverse osmosis (RO), and ultraviolet (UV) as treatment stages.
This research seeks to develop a process and tool for assessing the stability of an implant during shoulder replacement surgery. The proposed system will help shoulder surgeons decide whether an implant is sufficiently secure prior to completing the surgery. Researchers will measure how much torque it takes to loosen an Exactech shoulder implant from artificial bone models in a laboratory and relate this peak torque to the quality of the bone surrounding an implant.
Up to 30% of the population has a Fatty Liver Disease (FLD, a condition in which fat builds up in your liver). Non-invasive ultrasound assessment of this liver condition is an increasing demand in healthcare service due to its high risks leads to advanced liver diseases. However, an ultrasound-based examination has made the manual inspection a lengthy and tedious task and observer dependent. The proposed research aims at a computer-aided liver ultrasound assessment software toolkit facilitating the diagnosis of FLD.
Currently, mine water treatment systems within the Sydney Coalfield extract and treat mine water from depth with the aim to gradually âflushâ the mine pools of its acid-generating products and achieve good water quality over the long-term. However, since the deep, lower quality mine water is always being treated, significant annual operational costs (>$1 million) are being incurred. This project will evaluate the hydrodynamics and hydrogeochemistry of the mine pools and investigate treatment approaches that instead focus on the shallow, higher quality mine water.
Human activity near lakes can have a profound impact on the state of the lake. When nutrient-rich pollution enters the lake it can cause toxic algal blooms, decreased oxygen levels, a loss of diversity, fish kills and degradation of water quality. Aquatic plants may limit nutrients in run-off from entering the main lake. Aquatic plants along the shoreline take up the nutrients that potentially enter the lake before they get to the open water zone. At Chandos Lake, Ontario, the species of aquatic plants living along the shoreline have changed due to an invasive plant entering the area.
Mite and insect pests pose an ongoing threat to the sustainability of greenhouse vegetable production. Their control is critically reliant on pesticides. However, the intensive use of pesticides and the shrinking number of registered insecticides and acaricides increases the selection pressure against the few chemicals available and accelerates the evolution of resistance. This is critical for the two-spotted spider mite, aphid, whitefly and thrips populations as they are becoming increasingly difficult to control.
