Recent estimates of agricultural land on the Canadian prairies suggest that 1 million ha are affected by moderate to severe soil salinity. These areas are not suitable for seeding annual grain crops. Perennial forages have the potential to remediate saline soils through salt ion uptake, lowering the water table, improved soil biological activity, and weed suppression. This project will evaluate establishment and remediation benefits in saline soils with perennial forage mixtures compared to annual grain crops.
While the benefits of uranium production bring economic and strategic advantages for Saskatchewan and Canada, the legacy of its tailings, waste rocks, flooded mines, and industrial wastewaters are the drawbacks. To safeguard both human and environmental health, the mining waste streams need to be treated prior to their release to the environment. The current research project aims to use agricultural residue-based materials (e.g., wheat and canola straws) as a cost-effective and eco-friendly alternative to the more expensive commercial adsorbents for removal of selenium from mining wastewater.
A disturbing number of aggregate pop-out cases have recently been observed in newly poured concrete throughout the City of Saskatoon. A “pop-out” is a small, often cone-shaped void in a horizontal concrete surface left after a near-surface aggregate particle has fractured. Aggregate pop-outs can accelerate the deterioration of concrete sidewalks and can result in safety hazards to pedestrians and increased maintenance costs. Every year, the City of Saskatoon removes and replaces deteriorated sidewalk panels throughout the city.
The new Canada’s Food Guide has created controversies about milk and alternatives consumption by removing it as a stand-alone food group. Recent evidence shows an inverse relationship between consumption of dairy products and risk of osteoporosis. However, evidence on the association between milk and dairy consumption and the risk of cardiovascular diseases (CVD) have provided inconsistent and even conflicting results.
This project aims to characterize the interplay between gut microbiome community and BSF larvae in different diets and establishing a standard diet for BSF larvae. Commercialized BSF larva will be purchased and grown in a standard environment with different diets purchased from markets, collected from farmers, and artificially generated. The gut microbiome of BSF in both larval and adult stages reared on these diets will be extracted and sequenced.
After being bred, sows are commonly housed in individual stalls, which restricts their movement and impacts their well-being. For this reason, Canadian farmers are transitioning to housing sows in groups where sows have social interaction and greater movement. Groups can be formed right after breeding, with either a constant group (static: the same sows remain together until farrowing) or with smaller groups of sows being periodically removed and replaced (dynamic).
Metal halide perovskite nanostructures are materials with outstanding photoluminescent properties and very promising in optoelectronic applications. With this project, we seek to explore how several synthesis parameters influence the formation and grow of the nanostructures. We will use a suite of complementary structural characterization techniques that will provide a deep understanding of the near, medium and long-range order, and we will correlate the structural and photoluminescence properties.
Breast tumor harbours breast cancer stem cells (bCSCs), responsible for drug resistance or reduced effectiveness of chemotherapy drugs. The bCSCs can escape cell death induced by different treatment modalities, hence can survive and make a replica of the original tumor, contributes to its metastatic spread to distant organs, ultimately causing death. Therefore, targeting the bCSCs is the way forward. LMTK3 protein frequently over-produced in breast cancer cells contributes to drug resistance, and associated with poor survival of BC patients.
Today, 75% of anthropogenic greenhouse gas (GHG) emissions come from CO2 produced by the energy and chemical sectors. In Canada, extreme temperatures and a dispersed population cause the figure to be over 80%. New solutions that are either CO2-free or CO2-negative are urgently needed. The approach in this project is to produce solid carbon (C) instead of CO2, where the carbon can be sequestered into the ground or cement instead of being released into the atmosphere. The solution pursued in this project will decarbonize natural gas through methane pyrolysis.
Hyaluronic acid is a natural substance that is found in the epithelial, connective, and neural tissues in the human body and rooster comb tissues. It provides lubrication and acts as a cushion in the joints for different tissues of the human body. Currently, hyaluronic acid is widely used in pharmaceutical, cosmetics, and medical applications.
