Numerical investigations of arctic pipeline leaks and its fate

Leak detection and location identification of leakage of arctic pipelines in a timely manner is very important because the economic impact of an oil spill to its stakeholders can be huge. It could have an adverse impact on life, the environment, the economy and corporate reputation. In this study a numerical investigations will be employed using CFD packages for simulating pipeline leaks using various test fluids. The simulation will show the influence of small leaks on local pressure and temperature gradients, and the acoustic signature contours around the leak source. This will help to identify if it is within the detection thresholds of fiber optics cable. The theoretical minimum threshold values of the parameters in order to detect small chronic leaks will be determined. The CFD study will also reveal the consequences of the fluid dispersion and its migration path after the leakage

SSE – QV Studio – Pritam Priyadarsi

We are pioneering a state-of-the-art instrument that enables 3D imaging of single electron spins in individual spin-labeled biomolecules with unparalleled nanometer spatial resolution in volumes as small as (50-nm)³. This innovative capability allows for the direct determination of coordination among spin-labeled molecules, providing unique insights into the structure of biomolecular complexes that existing technologies cannot achieve. Our instrument incorporates several advanced features to attain exceptional sensitivity in detecting single electron spins within biologically relevant volumes. We utilize ultra-sensitive silicon nanowire mechanical sensors for precise spin detection and employ nanoscale current-driven field gradient sources to facilitate 3D magnetic resonance imaging (MRI). Additionally, we implement optimal control pulse sequences to enhance spin control and achieve long spin coherence times, which are essential for high-resolution imaging. To further increase imaging efficiency, our technology employs compressed sensing measurement protocols, streamlining the data acquisition process and enabling detailed 3D imaging of nanoscale volumes. Collectively, these features position our instrument as a revolutionary tool in biomolecular research, offering unprecedented access to structural details that are critical for understanding complex biological systems. We seek seed funding to commercialize this cutting-edge technology, which has the potential to transform the study of biomolecules and pave the way for advancements in areas such as drug discovery and disease diagnostics.

Effets des variables environnementales et de la contamination sur la diversité et la distribution des ostracodes de la mangrove de la Guadeloupe

Les ostracodes sont de tout petits crustacés qui, grâce à plusieurs de leurs caractéristiques, sont de très bons indicateurs de la qualité de l’eau. Le projet de maitrise de l’étudiante a pour but de déterminer quelles espèces on retrouve dans les mangroves de Guadeloupe, un écosystème déclaré en danger par l’Union Internationale pour la Conservation de la Nature (UICN) en 2024. Ce milieu est très important dans la lutte contre les changements climatiques, puisqu’il permet de grandement diminuer la quantité de carbone dans l’air en le stockant dans le sol. Une meilleure connaissance de l’état actuel de la mangrove et de son évolution dans le temps permettra un suivi environnemental plus rigoureux et pourra aider aux futurs efforts de conservation. Ainsi, ce stage aura pour but de former l’étudiante à l’identification des ostracodes dans le laboratoire du Professeur Peter Frenzel, expert dans le sujet, à l’Université de Jena en Allemagne. Cette expertise sera très utile à ramener au Québec, et même au Canada, où il n’y actuellement pas de spécialistes dans l’étude des ostracodes. En étant formée sur leur écologie et leur taxonomie, l’étudiante pourra appliquer ces connaissances aux environnements aquatiques québécois dans des projets de conservation futurs.

Exploring the employment experiences of Inuit receiving employability services at Ivirtivik

Presently and historically, Inuit have faced unequal access to employment. Douglas Health Research Center
members and Ivirtivik, an employment centre for Inuit, seek to create a collaborative, meaningful research
relationship to better understand employment facilitators and barriers for Inuit in Tiohtià:ke (the geographical
region called “Montréal”). Inuit cultural knowledge guides this endeavour, emphasizing inclusive, collaborative and
consensus-building research that respects Inuit worldview. Inuit will be invited to share their stories in focus groups
to develop a collective understanding of employment experiences. Inuit knowledge will be distributed in search of
solutions to improve collective well-being. Researchers, Ivirtivik and Inuit will contribute to future opportunities to
develop culturally safe tools to support Inuit employment by building bridges between Inuit and non-Indigenous
researchers.

Launching and Online Career Preparation and Self Development Course for Under Resourced Youth in Canada

Purpose and Background
The “Ahead of the Game Youth Mentoring Organization” (AOTG) seeks to address the significant challenges faced by “side-lined” youth, including lack of direction, underdeveloped skills, financial literacy issues, and career preparation barriers. AOTG aims to empower youth (ages 12-29) through mentoring programs focused on leadership, emotional intelligence, and life transitions, especially for under-resourced youth in Canada.

Building on prior efforts funded by Mitacs, which included an environmental scan of challenges faced by youth in rural Nova Scotia, the current project focuses on creating and launching an online education program to bridge gaps in youth development and readiness for life transitions. The program will include online courses, webinars, mentorship, personalized coaching, and community engagement.
Impact
This project targets societal challenges such as youth disengagement, lack of preparedness for life transitions, and mental health issues. By equipping youth with skills, resources, and guidance, AOTG intends to improve their educational and career outcomes, thereby fostering a more equitable and capable generation.

This structured approach leverages technical expertise, community input, and innovative methodologies to create scalable solutions for youth mentorship and development in Canada.

Elucidating Ion Transport and Catalyst Degradation Mechanisms in Proton Exchange Membrane Electrolyzers

As one of the most promising pathways to achieve zero-emission targets, Canada and Germany launched their respective hydrogen strategies. Polymer electrolyte membrane water electrolyzers (PEMWEs) for green hydrogen production and hydrogen-fed PEM fuel cells (PEMFCs) for zero-emission vehicles are two technologies considered to be crucial parts of the future hydrogen infrastructure in both countries. Although both PEMWEs and PEMFCs are in early commercial stages, in addition to cost, two major barriers to large-scale commercialization are their durability and the increasing concerns about the environmental impact of fluorocarbon-based polymer electrolytes. Development of strategies to enhance durability via new materials discovery or new component design requires a robust experimental-evidence-based understanding of the degradation and transport phenomena in the PEM and at the membrane-electrode interfaces. Using a diagnostic microfluidic cell, transport phenomena in the membrane and at the interface can be visualized to understand phenomena in existing materials and develop novel, fluorocarbon-free materials with a deeper understanding of their impact on long-term stability and large-scale commercialization of PEMWE and PEMFC. To ensure that results from the diagnostic cell accurately reflect phenomena in larger-scale operation, the findings will be checked and cross-referenced in a benchtop-scale setup.

Development of genetic engineering in microalgae

Biopharmaceuticals are pharmaceuticals that are produced in biological systems, as opposed to being made synthetically using purely chemical approaches. Biopharmaceuticals are becoming increasingly important today, as biological systems are very good at making pharmaceuticals with very precise activity within people and with fewer side effects. However, most of the conventional approaches used to make biopharmaceuticals suffer from shortcomings such as high cost and the need to remove human pathogens. On the other hand, microalgae overcome many of the limitations of the current systems. They are low-cost, safe to humans, and even edible. Microalgae are like very small plants, and plants were the original source of biopharmaceuticals, including the cancer drug, taxol. However, in spite of their many advantages, microalgae have not yet been used commercially for biopharmaceutical production. The purpose of this Mitacs Accelerate proposal is to develop tools which are crucial to harnessing the potential of microalgae for making biopharmaceuticals.

Refining Earth’s first exit from oxygenation

The first initial buildup of oxygen in the Earth’s atmosphere – the Great Oxidation Event – started around 2.5 billion years ago, where oxygen may have reached levels comparable to today’s atmosphere. Following its debut, atmospheric oxygen levels quickly crashed, coinciding with a contraction of the global biosphere. The geologic time period of the Orosirian (2.05 – 1.8 billion years ago) records Earth’s exit from oxygenation (“OXIT”) in addition to an evolutionary milestone – the emergence of Eukaryotes. Animals (including humans), plants, and fungi are all eukaryotic organisms and without the rise of Eukaryotes, life as we know it today would not exist. The Orosirian has been overlooked for understanding early life and the environments that eventually enabled it to proliferate. Fortunately, Orosirian aged carbonates, from the Great Slave Lake region of northern Canada, may just hold the very clues we need. Trace element concentrations of these samples will be measured at the University of Western Brittany. In doing so, the environmental conditions in the aftermath of OXIT, which enabled the advance of Eukaryotes, will finally be understood. This project will offer major breakthroughs to the fields of Earth and life history and critical metals.

An Experimental and Numerical Investigation into Phase Change Material Thermal Storage using High Voltage Electric Fields

The project entails an experimental and numerical investigation into the effect of adding seeding particles into a Phase Change Material (PCM) thermal storage system under the application of Electrohydrodynamics (EHD).In previous experiments we have seen an increase in heat transfer enhancement for the same applied electric field when we have added seeding particles. The objective of the project is to investigate the underlying physics of this effect by using Particle Image Velocimetry (PIV) to measure the velocity of the seeding particles.

Ecological Restoration: A scan for determining the true costs

In order to meet our City Plan and Climate Resilient Edmonton goals of restoring ecological networks, and natural and modified ecosystems, we need to understand the true cost of restoration. The cost of ecological restoration can encompass multiple factors adding complexity to an already complex task. This project will aim to gather information from other municipalities, organizations and literature on the costs of ecological restoration. This information will then be used to analyze what the average cost of restoration would be for the City’s different natural areas based on condition and other factors. This project will help support the City’s overall restoration efforts and help to develop new budgets for it.
