Acoustic wave propagation testing to determine quality in timber and timber products
(2020)Assessing and grading of raw materials in the timber industry is a key factor in the maximization of extracted value. Several different approaches are utilized to measure the quality of standing timber and sawn lumber. ... -
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 ... -
Alternative uses for waste products from biomass burners
(2021)Woody biomass has become an important source of renewable energy throughout the world. A major issue that has risen from the increased use of combustion technology to produce thermal energy is the large amount of waste ... -
Analysis of current and future Low Impact Development sites in Thunder Bay, Ontario
(2017)The rapid spread of urbanization in Thunder Bay has caused the increase of impermeable surfaces and the increase in flood incidents within the city. Another contributing factor to increased flood incidents is due to the ... -
An analysis of northern goshawk prey preferences by biogeoclimatic subzone across coastal British Columbia
(2020)This thesis investigates the dietary preferences of northern goshawk populations in second growth stands on Vancouver Island and the islands of the Johnstone Strait region on the BC Mainland Coast. Prey abundance was ... -
Analysis of using unmanned aerial vehicles in forestry
(2019)Unmanned aerial vehicles are a growing market within the forestry industry. They provide opportunities for enhancement of data collection, monitoring of wildlife, forest fire detection and monitoring, compliance monitoring ... -
Analysis on the influencing factors of forest natural regeneration in northern China
(2021)The purpose of this paper is to clarify that the differences in natural regeneration between the two forests in northern China are caused by precipitation, altitude, temperature, and canopy density. Similarly, the ... -
Analyzing impacts of brush saw and herbicide treatments on branching and stem quality in northern Ontario jack pine plantations
(2020)In an industry where new science is ever-evolving, forest managers must constantly look towards research to guide best practices in achieving the highest quality forest product. Three common silvicultural treatments ... -
Apparent competition and the differing effects of generalist and specialist predators on cervid populations
(2020)Apparent competition is an important ecological function that has been extensively studied in wild cervid populations, but little is known about how to manage it or why some cervid populations are more affected by it ... -
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 ... -
Application of Walki®Biomass cover as a better alternative to plastic mulching
(2022)Mulch is a material that works as a protective layer over the soil so as to retain water and prevent excess evaporation. They are either in the form of continuous sheets like plastic mulch or they come in a shredded form, ... -
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 data accessibility and quality: predicting the effect of impervious surfaces on water quality in urban centres on the west coast of Lake Superior
(2020)This research will critically examine the difference in data quality and accessibility between two cities through an analysis of predicting the effect of impervious surfaces on water quality. Through using the Impervious ... -
Assessing progress toward an effectively managed, representative, and well-connected global protected area network
(2022)Protected areas are a cornerstone of conservation efforts to prevent biodiversity loss. Aichi Target 11 of the Convention on Biological Diversity called for the area of protected areas to be increased to 17% of terrestrial ... -
