In water quality management, mathematical models are used to evaluate management alternatives, and to support the policy making process. Environmental models involve substantial uncertainty which can be very critical when striving to identify polluters, to direct the use of taxpayers' dollars, and to determine management strategies that have considerable social and economic implications.
A lack of physical infrastructure and the corresponding fear of harm are a significant barrier to urban cycling, and an impediment to the expansion of Curbside Cycle’s target demographic. Using outreach and education through a collaborative process involving partners Curbside Cycle and Cycle Toronto we will empower local experts, enlist local businesses as powerful community stakeholders, and foster coalitions of community support for improved bicycle infrastructure.
The aim of this internship is to investigate the possibility of a scaled-up green process to design, and develop an industrial plant to remove the hazardous materials from spent secondary materials such as spent petrochemical catalysts, in Atlantic Canada. The intern will be responsible to develop a whole process flow diagram, as well as a detailed cost analysis. By identifying a feasible environmentally-friendly process, the industrial plat will be able to treat various hazardous wastes locally, thus there are different potential short and long-term benefits to the partner organization
This project will upgrade the Climate and Infrastructure Forensic Analysis System (CIFAS), originally developed to characterize snow- and permafrost-related impacts to ground transportation and mine access roads in the Canadian North. My first objective is to enhance the analytical capacity of CIFAS by improving its ability to quantify uncertainties associated with empirical knowledge used to causally connect infrastructure service levels with climate-induced disturbances, as well as with climate projections from climate models.
The United States Coast Guard (USCG) recently introduced stringent regulations for the treatment of ballast water. Ultra-violet (UV) light is a useful technology in a ballast water treatment system (BWTS), for inactivating phytoplankton which could be invasive and harmful to humans and the environment. UV damages DNA and prevents replication, but the vital stain methods mandated in the USCG protocol do not detect UV damage. Alternative culture-based measures of reproductive capacity are yet to be approved, time consuming, and have limitations (not all species may grow).
Dans la conjoncture énergétique, économique et environnementale actuelle, notre société recherche des solutions profitables pour réduire ses incidences sur l’environnement et sa dépendance aux énergies fossiles. Parmi les technologies disponibles ou en développement, la culture intensive de microalgues à des fins énergétiques a été envisagée dès les années 70.
Dans un contexte de changements climatiques, les modèles prévoient une augmentation de la fréquence et de l’intensité des sécheresses estivales. Or le manque d’eau peut gravement affecter la croissance et la survie des arbres, et donc diminuer leur productivité. L’objectif de cette étude est de tester la capacité de résistance de jeunes arbres à un stress hydrique tel qu’une sécheresse estivale.
The proposed REM project aims at developing and installing a highly iconographic solar charging station that will help inspire and foster the expansion of local infrastructure for electric vehicles at York University. This effort is part of a plan to use this innovative solar charging station to offset the electrical needs of EVs and most importantly to attract autosharing companies to the campus so EVs can become highly accessible to everyone at the university.
Smart grid energy systems are considered the future of electrical grid management and delivery. These technologies and programs are innovative ways to ensure a reliable electricity grid, promote renewable energy, increase efficiency, and enhance consumer control. Smart grids operate as automated or computerized systems that centralize electricity grid control and ultimately provide a more resilient power grid. The research will examine how organizations, businesses, and jurisdictions can transition from a conventional grid management system to smart grid technologies.
Historical survey images of mountains, glaciers, vegetation, and river features captured during the 1906 Alaska Border Survey will be repeated on the Alsek River by PhD student Christopher Rhodes. The sites of the original images will be accessed by river rafting during expeditions with Canadian River Expeditions down the Alsek River. The goal is to track landscape and ecological changes using repeat photography. For the intern, this is a critical component of his PhD thesis.
