Linking soil moisture content and carbon dioxide fluxes: From batch experiments to process-based modelling
(University of Waterloo, 2020-02-19)The emissions of carbon dioxide (CO2) from soil to the atmosphere represent a major flux within the global carbon cycle. Soil CO2 fluxes depend on environmental factors including soil moisture and oxygen, and on intrinsic ... -
Lipid and condition analyses of West Greenland marine feeding Atlantic salmon (Salmo salar L.)
(University of Waterloo, 2018-09-20)A regime shift in the Northwest Atlantic in the 1990s caused changes to the diet and productivity of marine-feeding Atlantic salmon (Salmo salar L.) off the West Greenland coast. Investigations into the implications of the ... -
Lipid Deposition on Hydrogel Contact Lenses
(University of Waterloo, 2006)The primary objective of this study was to quantify and characterise lipid deposition on soft (hydrogel) contact lenses, particularly those containing siloxane components. Studies involving a variety of <em>in vitro</em> ... -

(University of Waterloo, 2020-01-24)Daptomycin is a calcium-dependent cyclic lipodepsipeptide that is used clinically in the treatment of infections caused by pathogenic Gram-positive organisms, such as methicillin-resistant Staphylococcus aureus. Another ... -
The Lipopeptide Antibiotic Daptomycin: Its Interaction With Calcium And Membranes And The Effects Of Membrane Lipid Composition On Its Activity
(University of Waterloo, 2018-01-22)Daptomycin (Dap) is a calcium-dependent cyclic lipodepsipeptide antibiotic used clinically to treat infections with pathogenic Gram-positive bacteria, including methicillin-resistant Staphylococcus aureus (MRSA). It targets ... -
Liposome Supported Metal Oxide Nanoparticles: Interaction Mechanism, Light Controlled Content Release and Intracellular Delivery
(Wiley, 2014-05-26)Zwitterionic phosphotydylcholine liposomes stably adsorb a number of metal oxide nanoparticles via its phosphate group. This is different from physisorption and fusion with SiO2. The hybrid materials can be internalized ... -
Liposome/Graphene Oxide Interaction Studied by Isothermal Titration Calorimetry
(American Chemical Society, 2015-03-15)The interaction between graphene oxide (GO) and lipid bilayers is important for fundamental surface science and many applications. In this work, isothermal titration calorimetry (ITC), cryo-TEM, and fluorescence spectroscopy ... -
Liquid Crystal State NMR Quantum Computing - Characterization, Control and Certification
(University of Waterloo, 2013-08-30)Quantum computers offer the possibility of solving some problems more efficiently than their classical counterparts. The current forerunner in the experimental demonstration of quantum algorithms is Nuclear Magnetic Resonance ... -
Lithium ion conducting inorganic solid electrolytes and all solid-state lithium batteries
(University of Waterloo, 2021-11-08)As the world transitions away from fossil energy to green and renewable energy, electrochemical energy storage techniques, especially rechargeable batteries, increasingly become a vital component for this transition. High ... -
Local and landscape drivers of aquatic biodiversity in urban stormwater management facilities
(University of Waterloo, 2022-05-20)Stormwater management facilities (SWMFs) are often constructed in urban areas to provide flood mitigation and runoff control, and thus replace some wetland functions. Yet, their suitability as habitat for wetland biota is ... -
Local Group Analogues
(University of Waterloo, 2012-09-27)The abundance of satellite galaxies is a critical small-scale test of the standard cosmological model. From comparing the predictions of structure formation in simulations with observations of Local Group dwarf galaxies ... -
Locality and Exceptional Points in Pseudo-Hermitian Physics
(University of Waterloo, 2023-05-26)Pseudo-Hermitian operators generalize the concept of Hermiticity. Included in this class of operators are the quasi-Hermitian operators, which define a generalization of quantum theory with real-valued measurement outcomes ... -
Localization and possible functions of Arabidopsis HOTHEAD protein
(University of Waterloo, 2016-10-26)Molecular analyses using sixteen insertion-deletion polymorphic markers revealed that somatic sectoring occurs relatively frequently during the course of normal vegetative development. This is the first report that documents ... -
