Flexural behaviour of spun-cast concrete-filled fibre reinforced polymer tubes for pole applications
(2007-07-05)In this study, the feasibility of utilizing the spin casting technique with structural Fibre-Reinforced Polymer (FRP) tubes and eliminating steel reinforcement is explored for the first time. This would make spun-cast FRP ... -
Thermal Properties of Green Roofs in Cold Climates
(2007-09-26)Green roofs have, in the past 15 years or so, gained increasing acceptance as a means of replacing or offsetting the lost of green space due to urban development and urban sprawl. Green roof systems can provide numerous ... -
Time and Patterns of Development of Dunes Subjected to Sudden Changes in Flow Depth
(2007-09-26)In unsteady flows, dune dimensions may vary considerably from fully-developed dimensions produced from a flat bed under a steady and uniform flow. Specifically, dune height and length are observed to lag discharge when ... -
The Structural Capacity of Repaired Manholes
(2007-09-26)Five manhole models, three composed of brick and two composed of concrete, were created in the laboratory with the goal of simulating existing manholes in the field that have been deteriorated by stress and corrosion. The ... -
Nonlinear finite element study of deteriorated rigid sewers including the influence of erosion voids
(2007-10-01)The service life of rigid sewer pipes is often controlled by joint integrity. Leaking joints can cause ingress of water and develop voids where surrounding soil has eroded. The influence of soil voids on the stability of ... -
A METHODOLOGY FOR ENVIRONMENTAL PROTECTION OF ONTARIO WATERCOURSES WITH RESPECT TO THE PERMIT TO TAKE WATER PROGRAM
(2007-10-23)The Ontario Water Resources Act requires a Permit To Take Water (PTTW) for withdrawals greater than 50,000 L/day. The permitting process includes a requirement to minimize the environmental effects of the withdrawal, but ... -
Investigating the stability of nitric oxide synthase quaternary structure to denaturant and temperature
(2007-10-30)A limitation to investigations of homodimeric protein dissociation is that the signals produced from methods such as fluorescence and circular dichroism represent both dissociation and protein unfolding that may be occurring ... -
Influence of Foundation Stiffness on Reinforced Soil Wall
(2007-11-02)The influence of yielding foundations on the mechanical behaviour of reinforced soil walls including wall deformations and loads (strains) in the reinforcement layers is very complex. Based on a review of the literature, ... -
Structural Behaviour of Steel Columns and Steel-Concrete Composite Girders Retrofitted using CFRP
(2007-11-16)Steel bridges and structures often need strengthening due to increased life loads, or repair due to corrosion or fatigue cracking. This study explored the use of adhesively bonded Carbon Fibre Reinforced Polymers (CFRP) ... -
Investigation of the Effects of Biofouling on the Hydraulic Properties of Wells in Fractured Bedrock Aquifers
(2007-12-18)The objective of this study is to improve the understanding of the effect of biofilm growth and biofouling on well performance in a fractured rock aquifer. The study was conducted by investigating biofouling in several ... -
Remote environmental sensor array system
(2007-12-20)This thesis examines the creation of an environmental monitoring system for inhospitable environments. It has been named The Remote Environmental Sensor Array System or RESA System for short. This thesis covers the ... -
Quantification of complex phosphorus removal reactions occurring within wetland filtration treatment systems
(2007-12-20)In a constructed treatment wetland applied to domestic wastewaters, long term studies and increased operational experience indicate that phosphorus removal is variable or inconsistent, especially in cold-climate applications. ... -
Post-Fire Assessment of Unbonded Post-Tensioned Concrete Slabs: Strand Deterioration and Prestress Loss
(2007-12-21)Unbonded post-tensioned concrete slabs have been widely used in Canada and the United States since the 1960s, as they allow increased span-to-depth ratios and excellent control of deflections compared to non-prestressed ... -
Ground movements during tunnelling in sand
(2008-01-02)During soft ground tunnel construction, if the face pressure of a tunnel boring machine is not strictly controlled, excessive ground movements will propagate vertically upwards causing significant damage to adjacent buried ... -
Laboratory study evaluating thermal remediation of tetrachloroethylene impacted soil
(2008-01-04)A laboratory study was conducted to assess the relationship between degree of volatile organic compound (VOC) mass removal from soil and heating duration, initial dense non-aqueous phase liquid (DNAPL) saturation, and grain ... -
An Aquifer-Well Coupled Model: a Refined Implementation of Wellbore Boundary Conditions in Three-Dimensional, Heterogeneous Formations
(2008-01-15)This paper presents modifications to two widely used numerical groundwater flow models in an effort to improve upon the interaction between a well of finite length and conductivity with the surrounding formation. The first ... -
