Hybrid lithium-ion battery and hydrogen energy storage systems for a wind-supplied microgrid
(Elsevier, 2023-09-01)Microgrids with high shares of variable renewable energy resources, such as wind, experience intermittent and variable electricity generation that causes supply-demand mismatches over multiple timescales. Lithium-ion ... -
Hybrid Virtual Holonomic Constraints for a 2-D.O.F. Bipedal Robot
(IEEE, 2015-06-25)We apply virtual holonomic constraints (VHCs) to a fully actuated Euler-Lagrange system with impacts : a bipedal walking robot consisting of a stance leg, swing leg and hip mass. We call these hybrid virtual holonomic ... -
Hydrodynamic shrinkage of liquid CO2 Taylor drops in a straight microchannel
(IOP Publishing, 2018-02-12)Hydrodynamic shrinkage of liquid CO2 drops in water under a Taylor flow regime is studied using a straight microchannel (length/width similar to 100). A general form of a mathematical model of the solvent-side mass transfer ... -
Hydrogel porosity controlling DNA-directed immobilization of gold nanoparticles revealed by DNA melting and scanning helium ion microscopy
(Royal Society of Chemistry, 2012-04-07)Immobilization of nanomaterials is important for many applications, including sensor development, biomaterials design and catalysis. DNA-directed immobilization has been widely used because of its high specificity and ... -
Hydrogen peroxide production in a pilot-scale microbial electrolysis cell
(Elsevier, 2018-09-01)A pilot-scale dual-chamber microbial electrolysis cell (MEC) equipped with a carbon gas-diffusion cathode was evaluated for H2O2 production using acetate medium as the electron donor. To assess the effect of cathodic pH ... -
Hydrologic function of a moderate-rich fen watershed in the Athabasca Oil Sands Region of the Western Boreal Plain, northern Alberta
(Elsevier, 2019-03)Peatlands are a dominant land feature in the Athabasca Oil Sands Region (AOSR) of the Western Boreal Plain (WBP), comprising >50% of the total land area, many of which are moderate-rich fens. The carbon stocks of moderate-rich ... -
Hydrophobic and Elastic Forces Experienced by a Series of Pyrene End-Labeled Poly(ethylene oxide)s Interacting with Sodium Dodecyl Sulfate Micelles
(American Chemical Society, 2018-07-30)A series of pyrene end-labeled poly(ethylene oxide)s (Py2-PEO(x) with x equal to 2, 3.4, 5, 6, 7.8, and 10 kg mol–1) were synthesized, and their interactions with SDS micelles were characterized by steady-state and ... -
Hydrophobic esterification of cellulose nanocrystals for epoxy reinforcement
(Elsevier, 2018-10-24)The reinforcing effects of native and modified cellulose nanocrystal (CNC) materials on thermosetting epoxies are investigated. CNC modification is conducted by grafting an activated medium chain fatty acid to substitute ... -
Hysteresis bifurcation and application to delayed FitzHugh-Nagumo neural systems
(Elsevier, 2021-08)Hysteresis dynamics has been described in a vast number of biological experimental studies. Many such studies are phenomenological and a mathematical appreciation has not attracted enough attention. In the paper, we explore ... -
“I gained a skill and a change in attitude”: A Case Study Describing How an Online Continuing Professional Education Course for Pharmacists Supported Achievement of Its Transfer-to-Practice Outcomes
(The Canadian Association for University Continuing Education, 2014-11-27)The convenience and flexibility of online learning clearly make it an attractive option for learners in professional development contexts. There is less clarity, however, about how it fares as a vehicle for enabling the ... -
"I Will Not Drink With You Today": A Topic-Guided Thematic Analysis of Addiction Recovery on Reddit
(ACM, 2022-04)Recovery from addiction is a journey that requires a lifetime of support from a strong network of peers. Many people seek out this support through online communities, like those on Reddit. However, as these communities ... -
Identifying behavioural characteristics of tobacco product and e-cigarette use clusters: A repeat cross-sectional analysis
(Elsevier, 2019-03-01)Background Youth may use a variety of tobacco products and e-cigarettes. However, there is a lack of evidence for the combinations of tobacco products and e-cigarettes commonly used by youth in Canada and whether youth ... -
Identifying Feasible Physical Activity Programs for Long-Term Care Homes in the Ontario Context
(Canadian Geriatrics Society, 2015-06-30)Background Structured exercise programs for frail institutionalized seniors have shown improvement in physical, functional, and psychological health of this population. However, the ‘feasibility’ of implementation of such ... -
Identifying Fenton-Reacted Trimethoprim Transformation Products Using Differential Mobility Spectrometry
(ACS Publications, 2018-04-17)A transformation product of trimethoprim, a contaminant of emerging concern in the environment, is generated using an electro-assisted Fenton reaction and analyzed using differential mobility spectrometry (DMS) in combination ... -
Identifying model error in metabolic flux analysis - a generalized least squares approach
(BioMed Central, 2016-09-13)Background: The estimation of intracellular flux through traditional metabolic flux analysis (MFA) using an overdetermined system of equations is a well established practice in metabolic engineering. Despite the continued ... -
Identifying patterns of alcohol use among secondary school students in Canada: A multilevel latent class analysis
(Elsevier, 2020-01)Harm from alcohol use depend not only on the volume of consumption but also on drinking patterns. This study identifies patterns of alcohol consumption in youth and investigates how these patterns vary across schools and ... -
