Humpback whales show remarkable recovery after the impacts of commercial whaling, and their consumption of essential food resources could affect local herring and salmon populations. Little is known about the feeding ecology of humpback whales in BC waters, despite their increasing importance to fisheries and tourism. Both humpback whales and fish are vulnerable to prey depletion, and the public have a vested interest in the future of humpbacks and fisheries in BC.
QUATERNION has partnered with BOEING USA on a flight validation and evaluation program using Unmanned Aircraft System (UAS) to identify the operational system that replaces the 900MHz Autopilot Whip Antenna, integration of the printed antenna system into the UAS and related connectorization, fiber optic and strain gauge instrumentation in support of the shape prediction system and associated flight testing.
There is much about the brain we still do not understand. But, one fundamental way to understand how the brain works is to know normal range of activity. For example, how does your physician know that you have normal blood pressure? Similarly, why did the medical community choose 120 over 80? The way we do that is to collect information from as many individuals as possible thousands upon thousands! When you collect information from many people, scientists are able to paint a very clear picture of how blood pressure (or any variable of interest) varies across many people.
On the coast of British Columbia, both eelgrass meadows and Pacific salmon species are declining, yet eelgrass community dynamics and reliance of juvenile salmon on these communities are poorly understood. We will assemble the first large-scale dataset from monitoring efforts of coastal BC organizations in order to assess eelgrass community diversity and structure across environmental and human disturbance gradients (including boating, fishing, and non-native species).
Global climate change is altering the conditions in which our ecosystems exist. As those conditions gradually shift, ecosystems may cross critical points and experience irreversible collapse. Managers need tools to identify those points before they are crossed. This project will test one potential tool in the bogs of British Columbia. At the verge of collapse, ecosystems are thought to slow down in how they respond to disturbance or damage. We are trampling bog ecosystems and measuring how plant communities respond based on whether they are experiencing long term drought or not.
The performance we require from our buildings is ever increasing. Heightened security needs, the push for increasingly efficient use of resources, improved comfort, flexibility of facility space, and changing threats from climate change or other environmental factors are some of the challenges facing designers and operators. There are a complex array of interrelated components that are necessary to confront these challenges. Integrating these systems effectively is essential to meeting the challenges facing designers while providing value to the client.
This project focuses on the pyrolysis of rice husks and the analysis of the resulting products, including biochar and bio-oil. Pyrolysis is the decomposition of organic matter under high heat in the absence of oxygen. This project examines the pyrolysis of rice husks. Rice husks account for 20% of the entire weight of the grain. Currently, many rice producers perform uncontrolled burning to dispose of the rice husks due to the high cost of transportation for proper disposal.
Ocean wave energy converters (WECs) are devices that utilize ocean energy to produce electricity or fresh water. A key stage in developing these devices is scale model testing in wave tanks, as it allows the power generation capabilities of a design to be evaluated at a much lower cost and with no environmental risk compared to full scale testing in the ocean. One of the challenges with designing scale models of WECs is the power take-off (PTO) system which can be infeasible to implement at small scales.
Since 2011, radiologists at Royal Jubilee Hospital (RJH) and Victoria General Hospital (VGH) have piloted a Rapid CT (CT = Computed tomography) program to provide same-day CT scans for patients referred directly by participating community physicians, with the intent of avoiding unnecessary ED (Emergency Department) visits. This research will test the hypothesis that the Rapid CT pilot project has reduced costs by reducing ED visits.
Proposed developments (pipelines, super-tankers) along the coast of BC have the potential to negatively impact (shell)fisheries. Direct monitoring of fisheries can only detect negative impacts which have already occurred; therefore, indicator species (meiofauna) and environmental variables are monitored to detect disturbances before productivity is impacted. Our project will monitor intertidal ecosystems (numerous species and environmental variables) spanning the entire coast of BC, across a gradient of human impacts, long term.
