Modeling the emission, transport, and fate of key micropollutants and their treatment using novel titanium dioxide nanomaterials
(University of Waterloo, 2018-01-31)Endocrine disruptive effects in fish have been observed in many watersheds worldwide. The presence of intersex (ova-testes) in particular is well-documented in the Grand River watershed in southern Ontario, and is associated ... -
Modeling the growth dynamics of <em>Cladophora</em> in eastern Lake Erie
(University of Waterloo, 2005)<em>Cladophora glomerata</em> is a filamentous green alga that currently forms extensive blooms in nearshore areas of Lake Ontario, eastern Lake Erie, Lake Michigan, and isolated locations in Lake Huron. The biomass, ... -
Modeling the Interactions of Antimicrobial Peptides with Cell Membranes
(University of Waterloo, 2022-09-09)Antimicrobial peptides (AMPs) are key molecules of the innate immune system, found among a wide variety of living organisms, including animals, plants, and humans. It is typically composed of cationic and has a unique ... -
Modeling the X-ray absorption of Neodymium ions in cuprate superconductors
(University of Waterloo, 2022-07-18)Electronic nematicity, a breaking of the rotational symmetry of the electronic structure beyond what is expected from the ionic displacements of atoms, has been identified in the (La, M)₂CuO₄ family of the cuprate ... -
Modeling Water Emission from Intermediate Mass Star Formation Regions
(University of Waterloo, 2008-09-22)In this research water emission is modeled from intermediate mass star formations regions placed at 1 kpc. Nine models are created to describe these regions of varying source luminosity ($L=100,500,$ and $1000L_{\odot}$) ... -
Modelling Biogeochemical Cycles Across Scales: From Whole-Lake Phosphorus Dynamics to Microbial Reaction Systems
(University of Waterloo, 2020-01-21)Lakes are ecologically, economically, and culturally significant resources that are, at the same time, very fragile and sensitive to human disturbances. During the last decades, intensified urbanization and discharge of ... -
Modelling effects of stormwater best management practices on urban stormwater runoff phosphorus
(University of Waterloo, 2024-01-15)Phosphorus (P) is a key limiting nutrient for algal growth in freshwater whose excess loading to freshwater bodies contributes to cultural eutrophication and the associated symptoms of water quality deterioration. Urban ... -
Modelling Legacy Nitrogen Dynamics in the Transboundary Lake Erie Watershed
(University of Waterloo, 2023-01-26)Lake Erie is a source of drinking water, recreation, and commercial opportunity for both the United States and Canada, making the protection of its water quality essential. In the past decades, Lake Erie's ecosystems ... -
