Research in Action: Bringing new life to 17th century choral music

If you haven’t heard of Henry Aldrich, the famous 17th century composer, architect and Oxford dean, you’re likely not alone.

But Lakehead University music professor and Orillia campus principal Dr. Dean Jobin-Bevans wants to convince you to tune in.

“I was immediately drawn to his work as it’s the music I love to hear and perform myself,” says Jobin-Bevans, who came across Aldrich’s archived manuscripts in 2013 during a sabbatical researching in the Christ Church Library, Oxford. “There is also a modern appeal to his music – it’s still accessible and relevant all these centuries later.”

Aldrich’s music, most of which are anthems composed for the cathedral at Christ Church, was written for both unaccompanied choirs or those singing with an organ accompaniment. Typically thought of as an English style of church music, choral anthems have a long history of performance in the Anglican tradition and are almost exclusively sung in English.

Henry Aldrich collected, transcribed and composed as many as 8,000 scores of choral music for cathedral performances during his career at the University of Oxford’s Christ Church college, as a way to inspire his own creative work and religious musical expression. A prolific 17th century English writer, theologian, philosopher, composer, and architect, he also served as Dean of Christ Church and as the University of Oxford’s Vice-Chancellor.

Intrigued by Aldrich’s unique approach to choral music, Jobin-Bevans set out to transcribe select pieces from the 300-year old collection, editing and creating musical scores for contemporary church choirs, instrumentalists, and music scholars. Working his way through original leather-bound, handwritten manuscripts, Jobin-Bevans spent six years editing and digitizing 20 different scores, updating elements such as time signatures and adding musical bars and vocal clefs.

A CD of the new editions was released in November of 2019 and some of Aldrich’s original manuscripts are also captured on the project website. Jobin-Bevans says that hearing the music performed for the first time by the Cathedral Singers of Christ Church, who also recorded the music for the CD, was hugely rewarding and speaks to the lasting quality of Aldrich’s work.

Viewing history through the late composer’s musical lens is another takeaway of the project, says Jobin-Bevans. “Aldrich grew up, was educated and appointed Dean during the period of the English Restoration, a time of great upheaval, politically and socially. His work reflects that history and tells us a lot about what his creative mind was thinking concerning the role and function of Restoration church music and liturgy.”

Jobin-Bevans also agrees a parallel can be drawn between himself and Aldrich that goes beyond the music.

“He was passionate about connecting architecture, logic, and math through music to both teach and inspire,” reflects Jobin-Bevans. “His work has been an inspiration to me and has kept me engaged in new ways to teach, lead as a principal, and continue building this lasting digital archive of his legacy.”

Dr. Dean Jobin-Bevans’ research is a partnership with the Christ Church Library, Oxford. Samples of the music are available at:https://www.chch.ox.ac.uk/library-and-archives/henry-aldrich-project. The full album, Henry Aldrich: Sacred Choral Music, can be purchased on iTunes or borrowed from the NAXOS Music Library through your local library.

Research in Action: Research helping to improve the efficiency of motors

As the negative climate effects of fossil fuel-based energy sources become more apparent, governments, scientists and industries around the globe are putting more resources into developing sustainable and environmentally friendly alternatives.

Locally, Dr. Mohammad Nasir Uddin is contributing to the effort with his research, funded through Natural Sciences and Engineering Research Council of Canada (NSERC) Discovery Grants, on optimizing the efficiency of wind energy and electric motor drives.

A professor in the Department of Electrical Engineering at Lakehead University, Uddin and his graduate students are working on wind energy conversion systems to achieve maximum power extraction from the wind and maximum output from wind generators. They do this by creating intelligent algorithms that mimic the human brain by telling the system what to do in any given circumstance.

To illustrate what an algorithm is, Uddin gives the example of a commuter on the way to work in Toronto. “As she heads down the highway, her brain has planned out the shortest and fastest route. That’s an algorithm. Then she hears on the radio that there is an accident up ahead. Her brain takes that new information and creates an alternate route. That’s another algorithm.”

Uddin’s team has also developed control algorithms that improve the power quality and dynamic performance of wind generators by responding appropriately and quickly to unpredictable abnormal variations of wind speeds or power system fault conditions. Thanks to this kind of research the creation of a cost effective and sustainable wind energy system can be achieved.

Another area of Uddin’s research involves loss minimization in electric motors. “Fifty-five per cent of the total electric energy produced in the world is consumed by electric motors,” says Uddin. “If we use the algorithms to force the motor to follow certain conditions so that voltage and current give the minimum loss, then we can improve the overall efficiency of the system and achieve the best motor performance.”

Uddin has shared his findings in 228 papers that have published or accepted in refereed journals and conferences including 53 papers in IEEE Transactions which is considered the top ranking journal in his area of research. In 2010 he won the Lakehead University’s Distinguished Researcher Award.

Uddin’s impact in the field of Electrical Engineering goes beyond his own research. After more than 25 years of teaching and research experience at various universities in Canada, the United States, Bangladesh, Japan and Malaysia he has mentored and inspired many students. They include 50 highly qualified engineers (nine Ph.D., 24 Master’s, 14 Research Associates and three Postdoctoral fellows) and 82 undergraduate students. Most have gone on to work for companies like General Motors, Mercedes Benz, Rockwell Automation, AMEC, Caterpillar and Schneider Electric where they continue to develop optimization algorithms that improve efficiencies in motor drives used in transportation, robotics, automotive and oil industries.

Dr. Mohammed Nasir Uddin is a professor in the Department of Electrical Engineering at Lakehead University; Coordinator of the Electrical Engineering program under the Lakehead-Georgian Partnership; and the Director of the Renewable Energy, Power Systems and Drive Research Lab located in Barrie.

Research in Action: Making mathematics more meaningful through culturally responsive education

Women smiling wearing pink frame glasses and a blue flowered shirtMath is not a four-letter word. But to those with rampant math phobia, it certainly feels like it. Dr. Ruth Beatty, Associate Professor in the Faculty of Education at Lakehead University’s Orillia campus often sees students who actively dislike or even fear math. To her the problem isn’t with math itself, it’s with how the subject traditionally has been taught.

She started her research career looking at how children understand math and how educators can best teach the subject. She found that by looking beyond numbers and symbols and by taking a more holistic approach to what it means to think “mathematically” teachers could make math more accessible and fun.

Nine years ago, while teaching in the Master's program at Lakehead’s Thunder Bay campus, Beatty made a fascinating connection that has guided her work since then.

“Some of my students were First Nations educators or had been teaching in First Nation schools and we were talking about the disconnect between Indigenous culture and mathematics education in Ontario curriculum,” said Beatty. “I started visiting communities to learn more.”

While working with the Elders she realized that math is naturally embedded in Indigenous cultural practices like beadwork or birch-bark basket-, snowshoe- and moccasin-making.

“Take a beaded bracelet, for example,” says Beatty. “There's so much math in it. There is patterning and algebraic reasoning, there’s geometric transformations, proportional and spatial reasoning. There's number sense and numeration.”

With that cultural connection in mind, Beatty began a study in 2012 with the Algonquins of Pikwakanagan First Nation and teachers from the Renfrew County District School Board at a school with 20 per cent Indigenous students and 80 per cent non-Indigenous students. The project partnered community members, artists, Elders, and Knowledge Keepers with Indigenous and non-Indigenous educators to co-plan math instruction for Grade 3 and 6 students based on Algonquin loom beading. Cultural and language teachings were also integrated into the math unit.

The results were overwhelmingly positive. Indigenous students got to share their heritage and gain a sense of pride in their own knowledge systems that were valued on the same level as Western curriculum. Non-Indigenous students gained an appreciation of Indigenous culture. Most importantly, both groups learned exciting new math skills in a fun and engaging environment.

Perhaps the best endorsement of the math classes came from the students themselves. At the end of a session, with students working in their designs, making calculations to determine how many beads they would need, the teacher told them to wrap it up, math class was over. They looked up in surprise. Wait? What? Math? They had spent three hours absorbed in their learning with no idea they were, in fact, doing math.

Beatty and her team have collaborated with nine more communities around the province including The Chippewas of Rama First Nation and Simcoe County District School Board. Her work shows that math doesn’t belong to Eurocentric culture or scholars. Math is all around us and if taught in inventive, positive, and culturally responsive ways, no one needs to be afraid of it.

Faculty of Education professor Dr. Ruth Beatty and her school board partners received funding from the Social Sciences and Humanities Research Council of Canada, CanCode, and the Council of Ontario Directors of Education to carry out this important research.

Research in Action: Uncovering the importance of human capital

Before he became a university professor and author, Dr. Kunle Akingbola had a successful career as a Human Resources (HR) professional. He was the HR manager for the Canadian Red Cross in Toronto while working on the second of his three Master’s degrees. As he grappled with choosing a thesis topic, his research advisor made a suggestion that would change the course of Akingbola’s work and his life.

At the time, the Red Cross had just taken over managing a homeless shelter over the winter for the City of Toronto, which was downsizing services to the non-profit sector. On top of their regular programs, Red Cross employees had to create and staff a completely new program that they would give up in six months time, only to bring back another six months after that.

Akingbola took his advisor’s advice and used the Red Cross case study as the basis for his Master’s thesis on non-profit HR management. That line of study eventually led to his Ph.D. dissertation, which examined the entire strategy of non-profit organizations across Canada and the impact of government funding and the environment.

Akingbola’s growing expertise led to part-time university teaching. He eventually left his HR career to become a full-time professor. Today he is Associate Professor of Human Resource Management and Organizational Behaviour in the Faculty of Business Administration at Lakehead University’s Orillia campus.

With numerous publications including books, chapters in edited books, and articles in leading journals, research continues to be a large part of Akingbola’s work, which looks at ways to optimize the effectiveness of non-profit organizations while increasing employee satisfaction and improving outcomes for the communities they serve. He encourages his students to get research experience by helping him do surveys and data sorting.

“Prior to my study, no one had ever looked at HR management in non-profit organizations, says Akingbola. “There had been research on volunteers, but not employees of non-profit organizations that make up a major part of the Canadian social sector and account for about nine per cent of Canada’s Gross Domestic Product (GDP).”

His vast personal experience in HR in non-profit and healthcare sectors combined with his extensive ground-breaking research give Akingbola rare insight and expertise into social purpose enterprises. He understands the fine line organizations are forced to walk to secure the funding that is essential to support their services. It’s especially frustrating in the face of what Akingbola calls “mission drift.”

“How do you manage people who joined your organization because they believe in your mission, but now you have to go in a different direction because that’s where the funding is dictating you go?” says Akingbola.

One thing he is certain of is the importance of the human component in non-profit activities.

“The nature of service is emotional and it is human based,” says Akingbola. “You can install an ATM on Jarvis Street in Toronto that gives out blankets and coffee to the homeless on a cold winter’s night. But it can’t dispense compassion. In that regard you can’t replace human capital.”

Dr. Kunle Akingbola is the lead author of the book "Change Management in Nonprofit Organizations: Theory and Practice" (Palgrave Macmillan, 2019) and the author of "Managing Human Resources for Nonprofits" (Routledge, 2015).

Research in Action: Pediatric vaccine may offer hemodialysis patients better protection against infections

 

 

 

 

 

 

Published in The Chronicle Journal Tuesday, April 7, 2020

BY JULIO HELENO GOMES

People undergoing treatment for kidney failure may be able to avoid further complications with doses of vaccines intended for children, suggests the findings of a project being conducted by Lakehead University and researchers at the Northern Ontario School of Medicine.

The five-year study involving patients with severe chronic kidney disease found that the risk of infections was decreased if they received vaccinations normally prescribed for infants.

“We see that a pediatric pneumococcal vaccine works nicely in these people,” says Dr. Marina Ulanova, the principal investigator. “It will be the best way to prevent infection, to use a pediatric vaccine rather than the one that is given to them routinely.”

Dr. William McCready says the purpose of these trials was to understand how best to protect patients with severe kidney disease from developing other serious health issues.

“Patients with kidney failure are more susceptible to infection because their immune systems are impaired by their kidney failure,” says McCready, who has worked as a nephrologist and internist across the Northwest for more than 30 years.

A Lakehead professor and researcher with NOSM, Ulanova’s background is in immunology and pediatrics. She is leading several projects related to infection and disease, particularly in Indigenous populations. Chronic kidney disease is a significant issue in Northern Ontario, which already suffers from high rates of diabetes.

“Chronic kidney disease is a huge issue in northern communities,” she says. “We know their immune system is weakened because of diabetes and kidney disease, and they need better protection against infection.”

The trials began in 2015 and include a mixed group of patients undergoing regular hemodialysis treatment at Thunder Bay Regional Health Sciences Centre. As a result of their compromised immune system, these patients are more likely to develop other problems such as pneumonia and blood stream infections, which can be fatal.

A total of 132 people were enrolled in the program. All received the second-generation pneumococcal vaccine, Prevnar13, and were followed for one year. One group was already immunized with the adult Pneumovax23 vaccine; the other was not. Assessment included immunological response, vaccine safety and longevity of protection.

“Pneumovax23 has some weaknesses,” Ulanova says. “It’s not very strong in inducing immune response. For this reason it was suggested to use the pediatric vaccine for immunization of adult people with weakened immune system. Indeed, we found Prevnar13 worked well in both groups and, moreover, people who have not been previously vaccinated with Pneumovax23 have even stronger immune response to Prevnar13.”

Gabrielle Gaultier, a PhD student, is assisting Ulanova on this project. Her role is to collect blood samples from patients, isolate cells from the blood, and quantify the results.

“We hope our research will contribute to determining an optimal pneumococcal immunization schedule to better protect patients with severe chronic kidney disease against serious pneumococcal infections,” she says.

Gaultier hopes to use this experience to pursue a post-doctoral position in the fields of immunology and microbiology.

The last participants were immunized in February 2019. Ulanova and her group are now into the laboratory phase of the work, analyzing this data. She hopes results can be published within the year.

McCready — who has held numerous positions with NOSM and the Regional hospital — was the physician supervisor for these trials.

“These studies are an example of the synergies that can be achieved when clinicians collaborate with scientists and we are both motivated by trying to help patients from Northern Ontario,” he says.

This study was supported by Pfizer and the Northern Ontario Academic Medicine Association’s Innovation fund.

Research in Action: Wabakimi partners with Lakehead for research and experiential learning

Students canoeing in Wabakimi - view of their backs

For over 20 years, Dr. Tom Potter, Professor in Outdoor Recreation, Parks, and Tourism (ORPT) at Lakehead University, has maintained a working relationship with Wabakimi Provincial Park.
More recently, Alexa Haberer, a Technologist in the ORPT program, has also been involved.
Each year, Potter and Haberer facilitate two-week research journeys for about a dozen third year undergraduate students in the ORPT program.

The journeys are the culminating project for their field exploration course. The trips have three main learning goals: expedition planning and preparation, which they undertake throughout the year; gaining experience in remote back county travel in the northwest ecoregion; and fostering first-hand data collection.

“I am extremely grateful to the staff of Wabakimi Provincial Park who have been highly supportive of our work over the years,” said Potter.

Shannon Lawr, Park Superintendent, Wabakimi Provincial Park, along with Shannon Walshe, Park Biologist, work with Potter and Haberer to identify the types of data collection that students could do to benefit the park, as well as canoe routes through the park that need attention. For example, students might document evidence of caribou, conduct a population study of beaver, identify and document plant species, or evaluate the state of campsites and portage routes.

“The students’ research and recreation-based activities, linked to our canoe routes, fill information gaps in terms of park operations and resource management,” said Lawr.

“The partnership with Lakehead also ensures the next generation of paddlers contributes to Wabakimi’s future and builds understanding as to why it is such a treasure,” he added.

Hannah Terejko, a fourth year ORPT and Natural Sciences student from Brantford, Ont went on last year’s trip, and echoes this sentiment.

“It is one thing to hear about a park and how amazing it might be, but to get to know it and connect to it like it is home creates respect, and drives the motivation to maintain its health,” she said.

Following the journeys, students compile comprehensive research reports that they present to the park. Through the students' detailed investigations, they make meaningful and unique contributions to park planning and management. They also expand their own vision and knowledge of the cultural, recreational and biological aspects of the park.

“It's a joy for me to watch students organise and conduct their data collection, and revel in their research accomplishments as they travel through some very challenging areas and environmental conditions,” said Potter.

During the trip, students are accompanied by qualified guides, including Lakehead faculty or staff. When possible, park staff members join the expedition group, too, which gives the students a chance to learn from someone working in their field. The experts, however, encourage students to lead. Students plan out their roles for the trip, rotating between leader, navigator, chef, head researcher, and assistant researcher positions.

“Everyone gets a chance to do everything, so each gets a chance to let the leadership skills they’ve developed over the program shine,” explained Haberer.

When asked about what she will take from the experience, Terejko reflected on these leadership skills.

“Being able to work with others and take initiative where it is needed, even in small tasks, can be more help to the group than it might seem, and is a great skill to bring into future jobs and careers,” she said.

Potter also noted the unique opportunity for not only hands-on learning but personal growth.

“Their projects encourage them to struggle more, see more, learn more, and appreciate more. And, they get to learn how challenging, exciting, and useful research can be,” he said.

Research in Action: Testing shines a light on effectiveness of UV lamps

BY JULIO HELENO GOMES

Originally published in The Chronicle Journal April 28, 2020

Lakehead University professor Dr. Siamak Elyasi makes an adjustment to an instrument he has developed to test ultraviolet lamps.


A study being undertaken by Lakehead University to analyze the performance of ultraviolet lamps used to disinfect wastewater before being released into Lake Superior is moving to the next phase of testing. The aim is not just to determine which lamps perform better, but how to improve the process and optimize costs.

“The City of Thunder Bay is looking to gain a better understanding of the aging process of the ultraviolet lamps,” explains Lindsay Menard, process engineer at the City’s Water Pollution Control Plant. “The intended goal of this project is to optimize the UV system and decrease operating costs.”

The study is a collaboration with Dr. Siamak Elyasi, an associate professor in Chemical Engineering. Elyasi’s broad interest is drinking water and wastewater treatment.

“Having clean water for all human kind is my dream,” Elyasi says. “Clean water prevents many waterborne diseases, which reduces health costs and improves the economy of the people and the prosperity of the country where they live.”

About 70 million litres of wastewater flows to the City’s Water Pollution Control Plant (WPCP) each day. The wastewater is treated through various processes before being discharged into the Kaministiquia River.  Preliminary treatment, the first stage of treatment, is where large objects such as rags, paper and wood debris are removed in the bar screens and suspended solids are removed in the grit tanks. 

The next treatment process, primary treatment, involves the organic materials and dissolved contaminants settling in clarifiers.  Following primary treatment, the wastewater receives secondary treatment.  The WPCP uses a secondary treatment process referred to as the Biological Aerated Filter (BAF) process.  The BAF process removes carbonaceous biochemical oxygen demand, total suspended solids, phosphorus and ammonia. 

The treated wastewater is disinfected with ultraviolet (UV) light to destroy pathogenic bacteria.  This process adds UV light, and therefore has no impact on the chemical composition of the wastewater.

Disinfection is the primary method of destroying disease-causing bacteria, to prevent the spread of waterborne diseases, says the City’s Menard. There are various methods of disinfection used by wastewater plants. The best option for the City of Thunder Bay, says Elyasi, is to have the treated wastewater exposed to UV radiation. To that end, from mid-April to mid-October — the “disinfection season” as defined by the Ministry of Environment, Conservation and Parks — the treated wastewater flows through a channel where light from an array of UV lamps damage the cells of micro-organisms that might be in the water.  When bacteria, viruses and protozoa are exposed to the UV light, they are rendered incapable of reproducing and infecting.

The system is equipped with more than 700 UV lamps, some costing hundreds of dollars each. The lamps have an expected life of 12,000 hours, but how effective are they as they slowly lose intensity?

Elyasi has developed an instrument to test a variety of lamps, to compare their performance over their life expectancy.

“You have to be very careful the UV lamp has the exact same performance or better,” Elyasi explains. “If they are less expensive, it doesn’t mean they are better, it doesn’t mean they are worse. You have to test them. If they can meet the performance of the original UV lamp, and are less expensive, that’s definitely the best choice.

“That is the goal of every manufacturer and plant operator: to reduce the cost of the operation,” he adds.

The project involved research/thesis student Mrunmayee Ravindra Nikam. Along with reviewing the literature during the development phase, she also performed experimental analysis of UV lamp output and collected data and documented the research findings. Her two years on this project gave her valuable experience in engineering research and designs.

“Throughout this research project I acquired numerous project management skills and further developed my abilities to think analytically, critically and logically,” Nikam says.

She graduated with a Master of Science degree in Environmental Engineering and plans to pursue a doctoral degree. Her ultimate goal is to become an environmental entrepreneur and implement a sustainable approach to preserve the environment.

Elyasi is pleased with the performance of the equipment and hopes it can be deployed at the Water Pollution Control Plant when the technology is proven.

“The UV process is an important step in the treatment of wastewater,” says the City’s Menard. “We are always looking for ways to improve our operations and we believe the work Dr. Elyasi is doing is one way to help us get better.”

Research in Action: Project guides climate change communication strategies

That climate change is one of the greatest challenges facing humanity is not news. This awareness, however, does not always translate into action. To move people to action, governments and organizations need to understand how best to communicate climate change information.

In March 2020, Dr. Lindsay Galway, Associate Professor in the Faculty of Health and Behavioural Science at Lakehead University and her team completed a project that sought to understand how citizens in Thunder Bay, Ont., and Prince George, BC, can become better engaged with climate change. Northern communities are particularly vulnerable to the effects of climate change. Although research has been conducted in the arctic, until now, little was known about public responses to climate change in the provincial norths.

“Provincial norths are unique case studies, because their economic wellbeing, culture, and history is often closely connected to resource extraction. They are also more remote and politically marginalized. But there is also a strong sense of place, of community, and of connection to the land,” said Galway.

The two-year project, funded the Social Sciences and Humanities Council of Canada, involved three components: representative postal surveys in Thunder Bay and Prince George; interviews with “climate champions” in each community who are engaged in climate change education and action; and lastly, the development of climate change communication strategies based on the gathered data.

The postal surveys involved using Canada Post’s address database to randomly select 2000 households for each community and then adjusting based on census data to make sure these households represented the demographics of the community as a whole. Surveys were mailed to these households asking about climate change beliefs and attitudes, impacts of climate change, and climate change action. The team received just under 400 completed surveys for Thunder Bay which is considered a strong response rate.

Key findings from the Thunder Bay postal survey in regard to attitudes and beliefs include that 95% of respondents believe climate change is happening, and 86% feel very or somewhat worried about climate change. 40% of respondents report experiencing climate change impacts in Thunder Bay such as shifts in seasonal patterns, changing frequency and intensity of precipitation, and extremes of weather.

Other key findings, those that relate to action, highlight areas for education and change. 70% feel that addressing climate change will have positive effects on the long-term health of our communities, but paradoxically, 51% are concerned about whether addressing climate change will increase taxes. Similarly, while 80% felt Thunder Bay community members should do more to address climate change, only 60% reported taking action themselves. 70% of respondents felt that climate change is more likely to be a threat in the future than in the present.

“People still think of climate change as a threat of the future – that’s key. Climate science clearly illustrates that it is problem of now. If we are going to act to address climate change, we need to do it in the next five years” emphasized Galway.

The research was supported by an advisory group in each community made up of representatives from organizations who are working to address climate change. Following analysis of the data, 30 people from the advisory group and other organizations took part in a climate change communication workshop in March 2020 to discuss the results of the research, and to build best-practices for communicating about climate change in Thunder Bay, facilitated by Galway and Dr. Paul Berger, Associate Professor in the Faculty of Education at Lakehead.

“Dr. Galway's research provides a solid foundation from which to take strong action. Scholarly evidence of strong local support for addressing climate change helped to secure a unanimous vote in favour of the City of Thunder Bay’s declaration of a climate emergency” said Aynsley Klassen, Program Coordinator at EcoSuperior, and a member of the research advisory group.

“Eco-superior is also able to use Dr. Galway's research to guide program development, increase the effectiveness of climate-related communications, and engage community residents in climate actions,” she added.

Another outcome of the project has been a video which recently was a finalist in the Social Sciences and Humanities Council Storytellers competition. The video was created by Robert Sanderson, a Master of Health Sciences Student at Lakehead, who was a research assistant on the project.

“Working on the project expanded my own interests and knowledge – it was a great opportunity to learn and make connections and gain research experience. I got to see a whole project from start to finish – to see the steps, the challenges and how to overcome them,” he said.

Sanderson’s video can be viewed at here and the final report from the project can be accessed here.

Dr. Michael Rennie is looking specifically at Lake Herring and Walleye to help inform adaptive management plans for Quetico Park.

June 19, 2020 – Thunder Bay, Ont.

A Lakehead University researcher has secured a $75,000 Quetico Foundation grant over the next three years to evaluate how invasive spiny water flea and climate change are affecting the early growth rates and mercury loads of fish at Quetico Park.

Dr. Michael Rennie, an Associate Professor in Biology, Canada Research Chair in Freshwater Ecology and Fisheries, and Research Fellow at the Experimental Lakes Area, is looking specifically at Lake Herring and Walleye to help inform adaptive management plans for Quetico Park.

“Recreational fisheries are a keystone to local economies, worth $1.3 billion in Ontario alone per year,” Dr. Rennie said.

“This is especially true in remote park regions like Quetico Provincial Park, a mecca for backcountry canoeists and fishermen. However, invasive species like the spiny water flea and climate change threaten these pristine systems, and may require a change in management strategies given these ongoing environmental changes,” he said.

“We are extremely pleased to have received this funding from the Foundation for our first Lakehead University/Quetico Foundation Research Program,” said Dr. Andrew P. Dean, Lakehead’s Vice-President, Research and Innovation.

“This project will yield important results with regards to the ecology at Quetico Park and impacts of climate change. The park is one of those pristine treasures in our own backyard. Understanding and managing changes to the wildlife and fish in the park is essential to sustainability and resilience within a changing environment,” Dr. Dean added.

“The Quetico Foundation is thrilled to be working with Lakehead, and in particular, with Dr. Rennie who has an outstanding background in aquatic ecosystems,” said Arthur Saunders, Chair of the Foundation’s Science Committee.

“The Quetico Foundation is dedicated to the protection of wilderness and we anticipate that Dr. Rennie’s research will add to our understanding of how Quetico Park’s environment is reacting to the forces of change,” Saunders added.

Research in Action: Mass timber building components tested at one-of-a-kind lab

Tucked in a corner of Lakehead University’s campus, overlooking the placid waters of the McIntyre River, sits a nondescript building. While it may not attract much notice, this facility is the centrepiece of research that may pave the way for new kinds of materials to be used in modern building construction.

The Fire Testing and Research Laboratory boasts a custom-designed furnace that provides crucial data on the fire resistance of construction materials, building components such as beams and columns, as well as floor and wall assemblies. And with changes to national building codes that allow wood as a primary material in buildings up to six storeys in height, the benefit to local forestry and manufacturing could be significant.

“Without this facility I wouldn’t have this opportunity for advanced research in this fast-developing area of structural fire engineering, and also to help businesses develop innovative products and to serve the community,” says Dr. Sam Salem, the lab’s founder and director and an associate professor in Lakehead’s department of Civil Engineering.

This world-class fire testing facility allows the testing of new engineered-wood products taking place at Lakehead. At the Civil Engineering’s structures lab, products such as glued-laminated timber (glulam) and cross-laminated timber (CLT) are tested for strength, durability and their behaviour under normal stresses.

Next door at the fire lab, the materials are subjected to various fire scenarios, where temperatures in the furnace can reach 1,300 degrees Celsius. “Testing structural components and assemblies in the fire lab is the final stage in the research program, which is basically the main thing we look at to see how the building components behave or can withstand loads when exposed to fire,” Salem explains. “We have to design a safe building system that can first stand the load without the fire, then we expose it to the fire as the extreme loading condition.”

Opened in May 2016 at a cost of more than $1.2 million, the fire lab is the only facility of its kind at a Canadian university.


“This is very unique testing because there are very few facilities around the world that can test like this under this extreme temperature,” says Salem.

Internationally recognized as an expert in the field of structural fire engineering, Salem has conducted dozens of large-scale research projects since he arrived at Lakehead in 2012. Over the years, he has helped train several dozen highly qualified personnel, such as post-doctoral fellows and graduate students. Recently, he and graduate student Cory Hubbard have filed a patent for an innovative beam-end connection configuration for mass timber structural frame systems, which can stand fire exposure for an hour without any additional fire protection.

Salem’s doctoral student, Adam Petrycki, is involved in a project regarding the behaviour of timber-concrete composite floor systems at normal and elevated temperatures, focusing on their use in mid- and high-rise timber construction. His role is to develop a research plan, design and carry out an experimental study, analyze the results and then develop a methodology for their design and application in future construction projects.

The benefits, Petrycki explains, will be to potentially increase the use of this type of mass timber systems in multi-storey buildings. With a plentiful and renewable resource such as wood, Canadian forestry sector and wood companies can develop more mass-timber products for domestic use and export.

“The field of heavy timber construction and the fire safety of buildings is an area of research I’m passionate about, and being able to conduct experimental studies in the unique setting of the LU fire lab has been a unique and rewarding experience,” Petrycki says.

Salem has attracted more than $1.6 million in research grants and awards, from, among others: the Natural Sciences and Engineering Research Council of Canada, Canada Foundation for Innovation, Ontario Centres of Excellence, the Northern Ontario Heritage Fund Corporation, the Ontario Mass Timber Institute, and the provincial Ministry of Natural Resources and Forestry.

Research in Action highlights the work of Lakehead University in various fields of research.
