The Effect of Thermally and Chemically Enhanced Biostimulation on the Hydraulic Properties of a Discrete Fracture Network in a Bedrock Aquifer
(2010-12-06)The impact of thermally and chemically enhanced biostimulation of indigenous bacteria in a fractured rock aquifer and the resulting changes in hydraulic properties of the discrete fracture network were investigated at the ... -
The Effect of Wall and Backfill Soil Deterioration on Corrugated Metal Culvert Stability
(2009-10-08)Ministries and departments of transportation are working to undertake assessments of deteriorated metal culverts. To assist with these assessments by developing rational methods of classifying culverts, to select those ... -
The Effects of Bio Content and Type of Resin on FRP Wet Layup Tensile and Bond Strength to Concrete and Durability Under Freeze-Thaw Cycles
This study focused on replacing conventional unsustainable resins currently used in the fabrication of externally bonded Fibre Reinforced Polymers (FRP) with bio-based resins. The first two phases of this study explored ... -
Effects of Bubble-Facilitated VOC Transport From LNAPL Smear Zones on Vapor Intrusion
Light non-aqueous phase liquid (LNAPL) sources can pose a significant threat to indoor air through vapour intrusion (VI). Most conceptual and numerical models of VI assume that the transport of volatile organic compounds ... -
The effects of climate and humic substances on disinfection performance in Arctic wastewater stabilization ponds
This thesis is an investigation of disinfection in wastewater stabilization ponds (WSPs) as it relates to adequate wastewater treatment and, ultimately source water protection (SWP) in northern, particularly Indigenous, ... -
The Effects of Climate on Microalgae Growth in Arctic Wastewater Stabilization Ponds
(2015-06-02)The research presented in this thesis consists of work conducted in two studies designed to evaluate temperature effects on microalgal growth in Arctic wastewater stabilization ponds (WSPs). These systems are commonly used ... -
