Hydraulic Tomography Analyses of Different Datasets for Subsurface Heterogeneity Characterization at Various Scales
(University of Waterloo, 2023-08-21)Hydraulic Tomography (HT) has been evaluated to be a robust approach for high-resolution characterization of subsurface heterogeneity. However, geostatistics-based HT may produce overly smooth distributions of hydraulic ... -
Hydraulic Tomography and Trichloroethene Dissolution in a Fractured Dolostone: Small Scale Laboratory Experiments
(University of Waterloo, 2011-12-21)In fractured geologic media, flow and contaminant transport are predominantly controlled by the fractures, their distribution and connectivity. The accurate characterization of fractured geologic medium, imaging of fracture ... -
Hydraulic Tomography in Unconfined Aquifers and the Importance of Geological Data: Laboratory and Field Studies
(University of Waterloo, 2017-01-10)This dissertation first demonstrates the effectiveness of hydraulic tomography (HT) in characterizing the heterogeneity of both the saturated and unsaturated zone parameters through a laboratory unconfined aquifer. ... -
Hydraulic Tomography: Field and Laboratory Experiments
(University of Waterloo, 2011-05-17)Accurately characterizing the distribution of hydraulic parameters is critical for any site investigation, particularly those dealing with solute or contaminant transport. Despite the fact that many tools are currently ... -
Hydride Generation as a Sample Introduction Technique for Detection of Arsenic by Microplasma
(University of Waterloo, 2023-12-08)Microplasma can be used as a portable analytical instrument for elemental analysis of samples due to their small size, low power consumption, low carrier gas consumption, and low cost. This is specifically important for ... -
Hydrobiogeophysics: Linking geo-electrical properties and biogeochemical processes in shallow subsurface environments
(University of Waterloo, 2018-12-13)Microbially mediated reactions drive (bio)geochemical cycling of nutrients and contaminants in shallow subsurface environments. Environmental forcings exert a strong control on the timing of reactions and the spatial ... -
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 Production and Utilization of Agricultural Residues by Thermotoga Species
(University of Waterloo, 2007-09-26)Abstract: Hydrogen can be a renewable energy source to replace conventional fossil fuels. Compared to current hydrogen production processes by consuming fossil fuels, biological hydrogen production has the advantage of ... -
Hydrogen Production by Desulfurococcus fermentans
(University of Waterloo, 2012-09-28)Desulfurococcus fermentans is a hyperthermophilic archaeon growing optimally at 82°C. This microorganism is an obligate anaerobe with optimal growth pH of 6.0. It is capable of producing H2 as an end metabolic product using ... -
