Bioenergetics of mixotrophic metabolisms: A theoretical analysis
(University of Waterloo, 2019-08-29)Many biogeochemical reactions controlling surface water and groundwater quality, as well as greenhouse gas emissions and carbon turnover rates, are catalyzed by microorganisms. Representing the thermodynamic (or bioenergetic) ... -
Biogeochemical cycling of nutrient silicon in a human-impacted large lake nearshore environment (Hamilton Harbour Area of Concern, Lake Ontario, Canada)
(University of Waterloo, 2017-12-14)The biogeochemical cycling of nutrient silicon (Si) through rivers, wetlands, lakes, and artificial reservoirs regulates the magnitude and bioavailability of Si delivered downstream and to the ocean (Frings et al. 2014; ... -
Bioinformatic insights into the diversity and evolution of bacterial toxins
(University of Waterloo, 2020-01-24)Bacterial toxins are a broad category of molecules ranging from small organic compounds and peptides to large multi-domain or multi-meric enzymes. Several important diseases are caused primarily by bacterial toxins including ... -
Bioinformatic Insights into the Impacts of External Stimuli on the Human Airway
(University of Waterloo, 2021-12-21)The airway epithelium represents a critical component of the human lung that helps orchestrate defences against inhaled substances including air pollution, allergens, bacteria, and viruses. To manage these continuous ... -
Biological responses in fish exposed to municipal wastewater treatment plant effluent in situ
(IWA Publishing, 2021-04-16)Effluents from municipal wastewater treatment plants (MWTPs) are complex mixtures of chemicals including endocrine-disrupting compounds (EDCs) and 17α-ethynylestradiol (EE2). The objective of this study was to evaluate ... -
Biological responses in rainbow darter (Etheostoma caeruleum) to changes in municipal wastewater quality in the Grand River
(University of Waterloo, 2017-09-27)This thesis is a synthesis of studies that explore the effects of urbanization on a small-bodied fish species, rainbow darter (Etheostoma caeruleum), in the central Grand River (Ontario, Canada) over time. This watershed ... -
BIOMECHANICAL ALTERATION OF CORNEAL MORPHOLOGY AFTER CORNEAL REFRACTIVE THERAPY
(University of Waterloo, 2006)<strong>Purpose:</strong> Although orthokeratology (non-surgical corneal reshaping, Corneal Refractive Therapy, CRT®) has been used for almost a half century, contemporary CRT's outcomes and mechanisms still require ... -
Biomimetic sensing based on chemically induced assembly of a signaling DNA aptamer on a fluid bilayer membrane
(Royal Society of Chemistry, 2012-04-18)The adenosine aptamer was split into two halves and linked to a fluid liposome surface; addition of adenosine resulted in aptamer assembly, which did not occur if the split aptamer was attached to silica nanoparticles, ... -
Bioorthogonal Modification of the Major Sheath Protein of Bacteriophage M13: Extending the Versatility of Bionanomaterial Scaffolds
(American Chemical Society, 2016-09-04)With a mass of ~1.6 x 107 Daltons and com- posed of approximately 2700 proteins, bacteriophage M13 has been employed as a molecular scaffold in bionanomaterials fabrication. In order to extend the versatility of M13 in ... -
Biophysical Investigations of the Interactions between Calmodulin and Nitric Oxide Synthase Enzymes
(University of Waterloo, 2017-12-15)Nitric Oxide (•NO) is an essential biomolecule that has physiological functions in neurotransmission, vasodilation and immune response. •NO is produced by a family of enzymes known as nitric oxide synthases (NOS). NOS ... -
Biophysical Modelling of Antimicrobial Peptide’s Interactions with Phospholipid and Lipopolysaccharide Membranes
(University of Waterloo, 2019-05-23)Antimicrobial peptides (AMPs) are naturally-occurring peptide antibiotics. The way they work has inspired a vigorous search for optimized peptide antibiotics for fighting resistant bacteria. Cationic AMPs cleverly utilize ... -
Biophysical Studies of Lipid Membranes and their Interactions with Amyloid Peptides
(University of Waterloo, 2015-06-19)Amyloid beta peptides are known to form amyloid fibrils which are implicated in more than 20 currently incurable neurodegenerative diseases, including Alzheimer’s, Huntington’s and Parkinson’s. The proposed mechanism of ... -
Bioretention cells under cold climate conditions: Effects of freezing and thawing on water infiltration, soil structure, and nutrient removal
(Elsevier, 2019-02-01)Bioretention cells are a popular control strategy for stormwater volume and quality, but their efficiency for water infiltration and nutrient removal under cold climate conditions has been poorly studied. In this work, ... -
Biosensing at an individually addressable electrochemical array
(University of Waterloo, 2006)In this thesis, a novel electrochemical array is reported. The array consists of two planar halves, each having four carbon screen-printed band electrodes (SPEs), orthogonally facing each other and separated by a spacer ... -
Bismuth Sulfide Nanoflowers for Detection of X-rays in the Mammographic Energy Range
(Nature, 2015-03-24)The increased use of diagnostic x-rays, especially in the field of medical radiology, has necessitated a significant demand for high resolution, real-time radiation detectors. In this regard, the photoresponse of bismuth ... -
