The effect of silica nanoparticles on colloidal stability of tannins

The use of water sources with high silica concentration has proven to be a major challenge for the operation of steam boilers. Despite advances in conventional technologies, high silica water (>150 mg/L) continues to have a major impact on the operation and efficiency of boilers mainly due to silica deposit, which reduces heat transfer.
This project will investigate the behavior of tannins as a function of colloidal silica concentration, pH, and salt concentration, using photometric dispersion analyzer (PDA) and dynamic light scattering (DLS).

Florasol Extraction Process Development of Essential Oil

This project will be with ANPI Canada Inc., a Canadian company focused on essential oil extract from softwood in Bolton, Ontario. Presently, ANPI uses various extraction techniques for isolation of essential oils particularly cedar oil from cedar leaves, branches, and mulch. These essential oils have applications in the food, flavor, fragrances, and pharmaceutical industries. ANPI have found that their current extraction methods do not provide a suitable yield of cedar oil.

Determining how differences between avid and lapsed anglers can improve license sales and angler satisfaction

Regardless of the numerous fishing opportunities, and cultural and historical significance of fishing in British Columbia, the number of freshwater fishing licenses sold to residents has been declining. Many British Columbia anglers are lapsed, meaning that they do not purchase a license every year. A better understanding of these anglers, and the difference between them and avid anglers (who purchase licenses yearly) will help Freshwater Fisheries Society of British Columbia to make regular fishing more attractive and accessible to different types of anglers.

Recovery of minerals as value-added products from source-separated urine

The Aerosan Urine-Diverting Dry Toilet is a dry toilet with urine diversion that is designed to be deployed in the field for humanitarian aid and to provide safe and affordable sanitation in a variety of settings worldwide. This source-separated urine contains almost 80% of the nitrogen, 60% of the potassium and 55% of the phosphorus that humans excrete, and these are the main minerals required by plants.

Kinetic and Reactor Models for Sugar-to-Glycol Conversion

The sustainable use of forest- and agriculture-based resources to produce clean fuels and value-added chemicals is an opportunity to reduce greenhouse gas emissions generated by non-renewable fossil fuels. Glycol, a valuable industrial chemical, can be derived from sugars that originate from agricultural and forest waste and byproducts using a catalytic process. S2G Biochem, located in Vancouver, is working to develop and demonstrate technology to convert sugars and polyols to glycols.

Predictive Models for the Manitoba Bio-Economy Atlas

The intern will develop a multi-year model of a biomass supply chain for Manitoba, which will comprise the back end for a web based Bio-Economy Atlas tool. The tool will create feasibility level assessments of the volume, consistency, variability, accessibility and logistics costs of the biofuel resource in Manitoba, including both conventional sources, such as agricultural residue, and unconventional sources, such as riparian biomass and cattails.

Predator Reduction and Habitat Influences: Impacts on Upland Duck Nest Success in Alberta Parklands

More than any other life stage, the hatching of eggs is the most important factor in the maintenance of dabbling duck populations. Rates of nest success are suppressed by predators like foxes, coyotes, skunks, and crows. Populations of these predators can be artificially high due to habitat alterations resulting from human development. The Delta Waterfowl Foundation proposes lethal trapping to reduce nest predation in Alberta parkland habitats. However, predator reduction programs can direct limited resources away from habitat-based alternatives, and are controversial.

Towards an operational database of forest bird abundance in British Columbia

Forest companies would like to reduce the number of birds, eggs, and nests that are negatively affected by logging. The problem is that we don’t have detailed knowledge of where every bird lives, so it’s difficult to make educated choices about where and how much forest to harvest. My research will provide a solution to this problem. I will relate bird data to forest characteristics like age and height to understand which forest types have the most birds, and to map out where birds are most likely to live.

Sustainable production of engineered wood products in Northwestern Ontario: Developing harmonized decision models and standards for local materials

The global demand for engineered wood products (EWP) is increasing and in the last two decades, timber has captured substantial market shares from the mineral-based solid construction materials, particularly in the construction of residential and non-residential buildings. Although, the production of glue laminated timber (Glulam) and cross laminated timber (CLT) engineered wood products has been growing in other provinces of Canada, there are no manufacturing facilities in Ontario to service the local and the Midwest and Great Lakes States markets.

Alberta High Resolution Wetland Inventory Methodology Development

This project aims to operationalize innovative methods for developing cost effective wetland inventories across Alberta by use of numerous sources of remote sensing data, namely light detection and ranging (LiDAR), synthetic aperture Radar (SAR), and optical imagery.
