Here, we focus on three applications: nanothermometry, optically detected magnetic resonance (ODMR), and second order autocorrelation. We present novel statistical and machine learning (ML) approaches to extract information… more Year: 2025, 2025

Abstract: <p>Stress can significantly affect neurobiological processes crucial for learning and memory. While repeated stress enhances fear memory, it impairs memory retrieval. In most studies, however, stress exposure typically preceded fear and extinction learning. Thus, the impact of previously acquired memories formed before exposure to stress is not well understood. The goal of this thesis is to… more Year: 2025, 2025

Abstract: <p>Innovative strategies to manage copious waste streams by upcycling feedstocks to valorized products which are then used in environmental remediation applications is an attractive circular economy model. This thesis explores this approach using waste wood generated from the milling of Chlorocardium rodiei (greenheart), a tropical hardwood species abundant in Guyana. We evaluate the… more Year: 2025, 2025

Abstract: <p>Forests play a critical role in the global carbon cycle, acting as carbon sinks that remove and store an estimated 0.4 to 4.1 Pg of atmospheric carbon annually. However, historical acid deposition and timber harvesting have disrupted nutrient cycles, leading to nutrient-deficient soils that hinder tree growth, particularly for sugar maple (Acer saccharum), a keystone species in Ontario… more Year: 2025, 2025

Abstract: <p>This study investigates associations between self-other differentiation (the ability to distinguish and coordinate the self and other perspective during social problem-solving) and specific ego functions (reality testing, judgement, sense of reality, object relations, and synthetic-integrative function) from a cognitive perspective in two groups of adolescents aged 12 to 18 years. One… more Year: 2025, 2025

Abstract: <p>The TATA-binding protein (TBP) is a key regulator of eukaryotic transcription initiation. The TBP homolog from Giardia intestinalis (gTBP) is highly divergent among all TBPs; notably lacking three of the four phenylalanine residues to unwind double- stranded DNA. I show that gTBP preferentially binds to single-stranded DNA (ssDNA) in two modes based on sequence and protein concentration… more Year: 2025, 2025

Abstract: <p>Mutations in the CLN7 (MFSD8) gene, causes CLN7 disease, a subtype of neuronal ceroid lipofuscinosis. MFSD8 is a lysosomal transmembrane protein that transports chloride across membranes. Experimentation regarding Dictyostelium discoideum revealed that mfsd8 deficiency altered lysosomal enzyme activity. During starvation, the aggregation of mfsd8¬¬- cells was delayed, and cells formed… more Year: 2025, 2025

Abstract: <p>This thesis explores the remediation of naphthenic acids (NAs) from oil sands process-affected water (OSPW) using activated carbon (AC) derived from petroleum coke (PC) chemically activated with potassium hydroxide. The research aims to identify the most effective method for the adsorptive removal of NAs by optimizing the use of economically viable KOH quantities and to apply Fourier… more Year: 2025, 2025

Rossetti accomplishes this by fostering the conversation regarding the challenges inherent in motherhood. Sing-… more Year: 2025, 2025

DWs are interfaces that separate regions
(domains) within a material that have different orientations of spontaneous polarization.
We investigated the electronic band structure of t2g electrons, confined to 90° charged do
main walls (CDWs) in… more Year: 2025, 2025

Abstract: <p>Microsatellites and microhaplotypes are genetic markers that, through DNA amplicon sequencing, generate genotypes to distinguish between individuals from wildlife populations. Here, these markers were sequenced in caribou (Rangifer tarandus) specimens using Oxford Nanopore's MinION DNA sequencer for the first time. Microsatellite loci previously sequenced with an Illumina MiSeq were… more Year: 2025, 2025

Abstract: <p>Trait variation in wild populations is shaped by the interaction of genetics and the environment. Given these interactions, this thesis explored trait variation in white-tailed deer from two angles: one focused on broad-scale environmental factors, the other on fine-scale genetic mechanisms. The first chapter investigated how climate and habitat variation influence antler size,… more Year: 2025, 2025

Games came to symbolize the dangers of a rapidly shifting technological and cultural landscape. This led to a series of moral panics that were centered upon these new, often complex, and increasingly realistic games that were apparently… more Year: 2025, 2025

Abstract: <p>Since the mid-Pleistocene, evolutionary histories of North American species were shaped by extreme climatic oscillations involving major range and habitat shifts at a rapid pace. The peopling of the continent and the subsequent human colonisation waves created further pressures affecting North American faunal and plant populations. Cervidae (deer family) are a diverse group which arrived… more Year: 2025, 2025

Abstract: <p>While hospitals were seen as high-risk zones during the COVID-19 pandemic, little is known about how older hospital volunteers and volunteer-based programs navigated that period. Using the Peterborough Regional Health Centre (PRHC) in Ontario, Canada as a case study, this thesis research explores the pandemic and post-pandemic challenges of older voluntarism in a regional health care… more Year: 2025, 2025

Abstract: <p>Rare earth elements (REEs) are in high demand globally for the green transition and high technologies. The growing demand leads to their release into aquatic ecosystems from various point and non-point sources, which creates urgency to investigate their fate and enrichment. This thesis further investigates the biogeochemical fate and REE uptake mechanisms throughout aquatic ecosystems.… more Year: 2025, 2025

Abstract: <p>In today's digital era, smartphone use is having a profound effect on family life. There is growing concern about parental phubbing, which occurs when parents ignore their children in favour of using their phones. This study examined how parental phubbing was associated with children's problematic media use (PMU), and problem behaviours (internalizing, externalizing,attention)… more
