Lake trout and their egg predators' ability to locate spawning substrate using olfaction
(2014-01-22)Lake trout spawning sites, and the substrate on these sites, are structurally unique in many ways. These sites are generally at the end of the fetch of a lake, close to shore (1 m) and composed of small to medium sized ... -
Landscape genetic analysis of population structure and barriers to gene flow in boreal woodland caribou (Rangifer tarandus caribou)
(2023)This study examines patterns of population genetic structure and gene flow of boreal woodland caribou (Rangifer tarandus caribou), which are experiencing declining population sizes across North America. Compared to ... -
Landscape indicators of Old Tower Road archaeological site (DbJm-6), Thunder Bay District
(2015-10-21)This thesis addresses two research objectives. The first investigates landscape factors in the paleo-environment which may have influenced the geographic positioning of an archaeological site near Thunder Bay. The time ... -
Late Holocene paleovegetation and fire history of Northern Lake of the Woods and the Woodland Period
(2023)This thesis analyzes two Late Holocene lake sediment cores which were collected from the vicinity of two archaeological sites in northeastern Lake of the Woods, Ontario: the Bundoran Site (DjKn-5) and the Bud Site (DjKn-6). ... -
Late Paleoindian biface manufacture: a case study from the Mackenzie I site (DdJf-9) near Thunder Bay, Ontario
(2015-06-15)The Mackenzie Sites appear to form part of the Late Paleoindian Lakehead Complex that occupied the unglaciated peninsula between Glacial Lakes Agassiz and Minong during the terminal Pleistocene. A number of sites and ... -
Lead oxide (PbO) for direct conversion detectors
(2017)There is great interest in the utilization of non-crystalline photoconductors for direct conversion medical X-ray imaging detectors. Lead Oxide (PbO) is one of the most promising candidates for application in general ... -

(2012)Polycrystalline Lead Oxide (PbO) is being investigated as a photoconductive materials for application as X-ray-to-charge transducer in direct conversion x-ray detectors used in fluoroscopy and radiology. Previous usage ... -
Leaf morphological and anatomical variations of paper birch populations along environmental gradients across Canada
(2014-12-12)Leaf morphology and anatomy have been found to vary considerably among tree species, and leaf characteristics have widely been used for analyzing plant growth and resource use strategies because of their structural ... -
Learning through relationship: in-context development for teachers of Indigenous students
(2019)In this study, I explore the experiences and qualities of productive learning relationships shared by Indigenous and non-Indigenous educators in K-12 public education contexts. I know from my own teaching experience and ... -
Lesbian and gay male identity development and online communities
(2012)The aim of this study is to broaden the understanding of how online resources including blogs, chats, websites, and social networking can help support identity formation in lesbian and gay people. More specifically, my ... -
The life cycle of human papillomavirus type 16 E6 variants and its effects on the innate immune system of host keratinocytes
(2013-02-01)Persistent infection with human papillomavirus type 16 (HPV16) is the primary aetiological agent for cervical cancer. Viral particles initiate their life cycle by infecting basal keratinocytes of epithelium and amplifying ... -
Light-weight federated learning with augmented knowledge distillation for human activity recognition
(2023)The field of deep learning has experienced significant growth in recent years in various domains where data can be collected and processed. However, as data plays a central role in the deep learning revolution, there are ... -
