One of the main safety concerns for dam structure is damage from the scour and erosion of rock mass downstream of spillways. Therefore, the design of dam spillways to discharge a wide-ranging quantity of water with minimum rock mass scour, is one of the most important issues in designing hydraulic structures that consider the energy […]

The increasing consumption of pharmaceutical to combat wide variety of diseases have caused pharmaceuticals as an emerging pollutant (EP) in water bodies and also in wastewater samples. The non-biodegradable nature of pharmaceuticals results their ineffective removal in biological systems including biological wastewater treatment units (BWTU). To combat the problem of secondary effluent from BWTU containing […]

Geophysical techniques are being increasingly used to monitor the structural conditions of dams, due to their widespread coverage and ability to detect subsurface issues, such as the development of seepage pathways. One such technique is Electrical Resistivity Tomography (ERT), which is sensitive to moisture content and porosity, meaning it can be useful for detecting areas […]

This project will assess the potential for using unmerchantable wood as feedstock for the production of biofuels and bioenergy. Large tracts of forests within the Great Lakes-St. Lawrence Forest (GLSL) consist of low quality pine- mixed woods that could supply feedstock if the unmerchantable wood were recovered in a sustainable and cost-effective manner. We will […]

Atmospheric oxidants are responsible for the degradation and ultimate removal of the vast majority of emissions into our atmosphere. A complete understanding of this chemistry is therefore essential if we are to develop effective and timely policies that address the pressing societal problems of air quality and climate change. Chlorine atoms are the least understood […]

Potatoes are among the top five crops worldwide. With the rate of climate change accelerating, the pressures on potato production systems (e.g., heat stress, water stress, pest pressures) will intensify adaptation efforts. Although climate change is already happening, it is often seen as an abstract and distant problem that diverts resources from current production challenges. […]

Habitat loss through anthropogenic landscape disturbance is one of the leading drivers of biodiversity loss, yet activities such as resource extraction and agriculture play a vital role in the global economy. Understanding impacts of such disturbances, through robust environmental monitoring protocols, is key to maintain a balance between economic growth and environmental sustainability. Cost-effective monitoring […]

Quantitative assessment of the thermal role and wear characteristics of multi-layer coatings in cutting tools is approached through the analysis of mechanical contact problem at the tool-chip interface and the constriction resistance phenomenon. The micro-contact configuration on the surface asperity level and the macro-contact configuration (contact pressure distribution and the size of the adhesion and […]

Water treatment plants in Manitoba use surface water with high organic content as their source of water supply. Organic carbon reacts with disinfecting chlorine forming potentially carcinogenic disinfection byproducts. Portage la Prairie water treatment plant is an example of typical Manitoba lime/soda water treatment plants facing the challenge of removal of organic carbon. Coagulation and […]

POS Bio-Sciences currently performs extractions, fractionations, and purifications on a variety of biobased materials including food ingredients, health ingredients, nutraceuticals, agricultural materials, and cosmetics. Access to improved separation techniques will allow POS Bio-Sciences to offer enhanced solutions to its current client base and potentially provide new services to the pharmaceutical industry, which has high standards […]

The use of composite materials for high temperature aerospace applications requires new studies in order to better understand the behaviour of these novel materials, and to generate appropriate design tools. The main goals of this project are to develop a set of numerical tools that will be used to predict the fatigue behaviour of advanced […]

L’érable à sucre est exploité depuis plusieurs siècles en raison de la concentration particulièrement élevée en sucre de sa sève. Malgré son importance économique, notamment au Canada, les paramètres qui régulent le mécanisme de la coulée à l’échelle de l’arbre sont encore mal connus. Des études précédentes ont mise en évidence l’influence des nombreux paramètres […]
