A breathing machine (ventilator) is the foundation of the intensive care unit and has saved many lives but it is associated with lung injury. Collapse of parts of the lungs (atelectasis) is common in these patients due pressures on the lungs from lying flat for long periods of time. Alveoli are the small sacks in the lung where gas exchange occurs. During lung collapse, some of the alveoli close during part or all of the respiratory cycle. This opening and closing of the alveoli causes lung injury and alveoli that remain open can become over distended and injured.
Problem: Airports are increasingly important, both economically and socially, for the movement of people and goods. A major risk faced by airports is the potential for collisions between aircraft and birds (bird strikes). Bird strikes are dangerous and expensive, with costs including the repair of damaged aircraft and of closed runways delaying flights and leaving planes in the air until they are cleared.
Objective: We will determine whether pest control of insects around airfields can decrease the abundance of foraging birds near runways and reduce the risk of bird strikes.
The successful commercialization of new cathode materials for lithium ion batteries requires an improved and detailed understanding of the correlations between their structure, properties, and performance. Such a correlation will provide a foundation for better understanding the degradation mechanisms and optimized operating conditions for these cathode materials; pairing new battery materials with ideal applications and standardizing the methods by which these materials are evaluated.
Canadas coastal regions are an excellent source of marine renewable energy. These regions are also popular with marine mammals, providing good feeding opportunities. However little is known about how marine mammals will be affected by tidal energy developments. Concerns include the impacts of sound on animals ability to find food and navigate, the indirect effects of changes in prey distribution and abundance, and the direct impacts of collision with tidal energy structures in the water column.
The Northern Gateway Pipeline and similar projects propose to transport oil from Alberta to tidewater terminals in British Columbia and eastern Canada. Accidental release of petroleum distillates and related by-products would have consequences on the marine ecosystem. To evaluate spill implications for seabirds, we propose to develop and apply molecular tools to assess toxicological and health endpoints in selected seabird monitoring species, using a combination of laboratory and field research.
Influencer marketing is a new and innovative way for brands to target their customers on social media in a highly accurate and trusted way. Brand partners work with hundreds of influencers over a period of time, which is called a campaign, to create marketing material. This marketing material is shared by both the brand and influencer to the audience of the influencers, who are followers on social networking platforms such blogs, YouTube, Instagram, and Facebook. A key challenge in influencer marketing is to identify influencers with the greatest social networking reach.
Across British Columbia, pacific salmon species provide nutrients for coastal food webs and ecosystems by returning to their natal rivers to complete their spawning cycle. As salmon are the main prey species of bald eagles, it is essential to further understand the effect that the current decline in salmon populations across British Columbia could have on the foraging behaviour of these apex predators.
People who use drugs (PWUD) face significant barriers in obtaining affordable housing. Single room accommodation (SRAs) housing have thus signified last resort housing for structurally vulnerable urban populations, including PWUD. While the health impacts of SRA housing among PWUD are well documented, little is known about the ways social-structural environments of SRA housing distinctly impact womens risk of overdose.
The overall objective for this project is to support the research of two masters students who would help advance the methods for modelling energy-climate policies, a field in which EMRG in the School of Resource and Environmental Management at SFU is one of the leading research units in the country and in which Navius Research Incorporated is the leading Canadian consulting firm, providing support to governments and other stakeholders in the development and assessment of energy and climate policy.
In general, hospital based medical personnel usually have little or no objective data describing an individual patient?s pre, intra and post-operative (perioperative) movement and activity. We are developing low cost and easily deployable technologies to monitor patient activity patterns and the associated intensities. We want to objectively identify medically important indicators of normal versus abnormal postoperative evolution.
