Enhanced hydrolysis of polyethylene terephthalate (PET) plastics by ozone and ultrasound pretreatment
(2021)The rapidly accumulating post-consumer polyethylene terephthalate (PET) plastics pose a great threat to our environment as they constitute one of the most used products in our day-to-day life. As a result, degradation ... -
Evaluating DNA Extraction and Analysis of Ancient Seeds: A Study in Peach
(2015)The peach (Prunus persica) is one of the most widely grown stone fruit in the world but its origin and domestication is still being debated. Genetic research has focused on identifying desirable genes for agricultural ... -
Evaluating spatial variation in food web connectivity and energetics within the Lake Superior fish community
(2019)Habitat coupling integrates energy between habitats, a process known to contribute to food web stability, and has been observed in Lake Superior. The degree of coupling differs among species, but the extent to which it may ... -
Evaluating the utility of a point of care device to assess physiological differences among wild boreal fishes
(2022)With the increasing risk of anthropogenic impacts in boreal ecosystems there is a need for tools to rapidly assess impacts on organisms and properly inform resource managers. Though well-researched, the i-STAT a portable ... -
Evaluation of Anti-E6 Single Domain Antibodies for the Treatment of Human Papillomavirus-related Cancer
(2022)The HPV16 genome encodes two oncoproteins, E6 and E7, which are essential for viral carcinogenesis. While E7 promotes cell proliferation, E6 abolishes the resulting p53-dependent apoptotic response. We hypothesized that ... -
Examining the Role of Ascorbic Acid in Prevention of Heterotopic Ossification
(2016)Heterotopic ossification (HO) is a condition in which mature bone forms in a non-osseous tissue following extreme trauma such as injury or surgery (1]. It is thought that a particular cell type known as mesenchymal ... -
Existence and distribution of serotonin and its 5-HT2-like binding site in the brain : pituitary axis of juvenile and sexually recrudescing female rainbow trout (Oncorhynchus mykiss)
(1999)In the first phase of this study, mammalian serotonin2-like (5-HT2-like) binding sites in juvenile rainbow trout (Oncorhynchus mykiss) hypothalamus, were examined by radioligand binding assay using the tritiated analog ... -
Exploring the effect of predator experience on Yellow Perch (Perca flavescens) behaviour and predator recognition
(2020)Recreational and commercial fisheries are important resources that can be vulnerable to disruption by invasive species, particularly the introduction of top predators into water systems that have not previously supported ... -
Expression of oxidative stress response genes in Campylobacter jejuni biofilms / by David Andrew Brookes.
(2007)'Campylobacter jejuni' is a Gram-negative microaerophilic bacterium that is widely believed to be the number one cause of food borne gastroenteritis and diarrhea caused by bacteria. The ability to form biofilms may provide ... -
Expression of T4 lysozyme gene in escherichia coli and trichoderma reesei
(2014-01-22)The T4 lysozyme, from bacteriophage T4, has the ability to lyse bacterial cell walls; thus it has attracted immense attention as an antimicrobial agent. Nonetheless, the production of T4L cannot meet our needs. All of the ... -
Extraction of phytochemicals betulin and betulinic acid from the chaga mushroom and their effect on MCF-7 Cells
(2018)Chaga mushroom (Inonotus obliquus) grows on birch trees found mainly in temperate regions like Canada, Northern United States and Siberia. It contains phytochemicals such as betulin and betulinic acid, which are a ... -
Factors affecting the distribution and transmission of Elaphostrongylus rangiferi in caribou (Rangifer tarandus caribou) of Newfoundland
(2000)Elaphostrongylus rangiferi is an introduced parasite in caribou (Rangifer tararuhts caribou) of Newfoundland and has caused at least two epizootics of cerebrospinal elaphostrongylosis (CSE), a debilitating, neurologic ... -
Factors influencing distribution of aquatic macrophytes in a small northwestern Ontario lake
(1970)In October, 1968, 5.0 Kilograms of wild rice (Zizania aquatica L.) seed were planted at 11 selected sites in Grassy Lake, in an attempt to introduce a self-sustaining crop. Some success was obtained at all sites, subject ... -
Factors influencing thermal variability and fish distribution in small boreal steams / by Lisa McKee.
(2010)The spatial variability of stream temperature is an important component of habitat within streams providing optimal temperatures for foraging and thermal refugia for sensitive species such as brook trout. Riparian shading ... -
Factors that predict brook trout distribution, thermal habitat, and abundance in Northwestern Ontario streams
(1995)Predictive models were developed to improve the understanding of stream-resident brook trout (Salvelinus fontinalis) populations and habitat in northwestern Ontario, and to facilitate protection of stream-resident brook ... -
Fetal programming from sub-lethal radiation: glucose metabolism in the liver and brown adipose tissue
(2018)Exposure to ionizing radiation contributing to negative health outcomes is a widespread concern among the public, scientific community, and workers in the nuclear energy industry and diagnostic imaging field. However, ... -
Floristic composition and functional stability of black spruce-Kalmia shrub savannah
(2023)Scope: In eastern Canada, black spruce (Picea mariana)-Kalmia angustifolia forest revert into forest, or become Kalmia heath, or Kalmia-spruce shrub savannah (SS) depending on fire severity. My main research objective ... -
Floristic structure, composition and depth of edge influence at buffer and wildfire edges along small boreal streams
(2009)Within the boreal forest of northwestern Ontario clearcutting and fire are the most common edge-creating disturbances. Along streams, wild fire consumes the majority of trees to the edge of riparian zones. However, forest ... -
Foraging time activity study of breeding songbirds in a successional white spruce community
(1999)I investigated the amount of time spent on foraging by birds in a successional white spruce community, during semi-monthly time blocks, in the context of flying, singing and other activities. Five hypotheses were tested: ... -
Freeze-thaw effect on selected fecal indicator bacteria : Escherichia coli and Enterococcus faecalis / by Nicole A. Hawdon.
