Advanced separation and anaerobic digestion technologies for value-added bioproducts and biofuel from pulp and paper mill wastes
(2022)In the first research project, the extraction of hemicellulose from the process water and synthetic hydrolyzate using liquid-liquid extraction (LLE) was examined. Specifically, the effects of the main experimental variables ... -
Advances in operations research models used in the gold mining industry
(2023)The topic addressed in this dissertation is a set of economically important operational problems in the gold mining industry that are solved using mathematical models of operations research. More specifically, the main ... -
Application of UASs to augment ground surveys in cranberry agriculture development: a proof of concept for the integration of UAS into the site identification and monitoring of cranberry farms in Newfoundland
(2017)Assessing the potential for developing wetland environments into cranberry agricultural lands is time consuming and expensive. The addition of unmanned aerial systems (UAS) to augment current ground survey techniques has ... -
Assessing community forest resources to determine potential for biomass district heating in one rural and one remote First Nation of Northwestern Ontario
(2016)The purpose of this thesis is to explore the feasibility of using biomass in rural and remote First Nations for the purpose of supplying biomass district heating plants. The availability of forest resources, including the ... -
Assessing the effectiveness of airborne thermal technology for delineating environmental thermal effluent
(2019)Bruce Power Generating Station is located on the shores of Lake Huron and is responsible for generating 30% of the Province of Ontario’s electrical need on a daily basis. Lake Huron is the 5th largest freshwater lake by ... -
Assessment and evaluation of soil health indicators with changes from boreal forest to agriculture in Thunder Bay, Ontario
(2022)The boreal forest is one of the most extensive biomes in Canada at an estimated 2.7 million ha. The requirement for a growing agricultural sector, along with a currently warming climate, has accelerated the conversion ... -
Autonomous surface vehicle for mechanized bathymetric surveys
(2022)This study evaluates the efficacy of an Autonomous Surface Vehicle (ASV) constructed from inexpensive consumer off the shelf components for suitability in surface-based bathymetry of large-scale tailing impounds found ... -
Carbon storage dynamics and tree growth response to species diversity in boreal forests
(2018)The boreal forest plays a critical role in regulating the global carbon (C) cycle. Both wildfire and harvesting affect ecosystem C. However, the long-term recovery of forest C storage with a diverse range of overstory ... -
Changes in winter habitat use by mammals following commercial thinning of lodgepole pine (Pinus contorta) in west central Alberta
(2010)In 1996, Millar Western Forest Products initiated an adaptive management experiment to assess the potential benefits of commercial thinning and to monitor its effects on winter habitat use by multiple mammalian species, ... -
Characterizing the flow regime in Brook Trout (Salvelinus fontinalis) incubation habitats and the implications for management in a hydro-regulated river
(2018)Hydropower accounts for more than one third of Ontario Power Generation’s electrical production. Hydroelectric development often occurs on rivers that also support recreational fisheries. The construction and operation of ... -
Climate change impacts on the health and livelihoods of Indigenous communities in Northern Ontario
(2021)Climate change is expected to affect people’s health and livelihoods in northern Indigenous communities more adversely than in others due to existing socio-economic conditions and direct reliance on the environment to ... -
Community-powered local energy planning and transitioning in off-grid northwestern Ontario First Nation communities
(2019)Accessing reliable and affordable electricity is a challenge for Canada’s remote First Nations in northwestern Ontario. These off-grid communities rely on expensive and environmentally harmful diesel-powered electricity, ... -
Comparative analysis of the properties of tamarack (Larix laricina (Du Roi) K. Koch) particleboard and thermally treated oriented strand board (OSB)
(2014)Engineered wood products (EWPs), for example, particleboard and oriented strand board (OSB), are normally made from wood residuals or small particles of underutilized wood species for replacing solid sawn products as its ... -
Comparing Aboriginal community-based criteria and indicators in forest management planning
(2018)Criteria and indicator (C&I) frameworks have been developed and implemented on national and international scales to measure sustainable forest management. The purpose of this research is to examine the reasons why ... -
Comparing the spatial pattern of fire and harvest disturbance in boreal Ontario watersheds
(2016)Fire and harvest are both major sources of disturbance in Ontario’s boreal forest. They are largely responsible for successional patterns in forest vegetation, and influence regimes of hydrologic change in boreal streams, ... -
Deploying an unmanned aerial vehicle (UAV) equipped with a multispectral sensor for detecting between differing levels of barley (H vulgare L.) fungal diseases in Northern Ontario
(2017)To date, no studies exist exploring the multispectral detection of fungal diseases in barley (H Vulgare L.) with UAV imagery. The purpose of this work was to determine if the spectral response (VI) of barley fungicide ... -
Diversity, phenology, and host associations of wild bees (Hymenoptera: Anthophila) in Thunder Bay, Ontario
(2020)Although extremely important to the functioning of productive ecosystems, wild bee communities are at risk due habitat loss and agricultural intensification. Wild bee species surveys provide valuable information on the ... -
Dominance and competition: a giving-up density analysis of rank-based foraging decisions of small groups of confined bison (Bison bison)
(2023)Socially foraging animals such as bison (Bison bison) modify their foraging behaviour based on social status and food availability to maximize individual fitness. Winter feeding trials were performed on juvenile bison ... -
Drought effects on soil enzyme activity
(2021)Soil extracellular enzyme activity (EEA) is a strong predictor for soil health. EEA cycle nutrients within terrestrial systems, processing carbon, nitrogen, and phosphorous, while also mineralizing and stabilizing gas. ... -
