Best Productivity Practices Implementation Index (BPPII) for Infrastructure Projects
(University of Waterloo, 2013-08-22)According to the Nobel Prize winner Paul Krugman, “productivity isn’t everything, but in the long-run it is almost everything”. It is unfortunate that the productivity in the construction industry has lagged behind the ... -
BIM-Based Decision Support for Evaluation of Architectural Submittals during Construction
(University of Waterloo, 2014-07-15)Submittal review is a formal process that takes place after construction has begun. All materials, equipment, and processes submitted by a contractor are evaluated for compliance with specifications before they can be ... -
Biofilm Dynamics in Drinking Water Biofiltration & Downstream Nanofiltration Biofouling
(University of Waterloo, 2018-05-17)Natural organic matter (NOM) is a concern in many surface waters and must be removed by water treatment processes for cost-effective production of safe and aesthetically pleasing drinking water. Biological filtration is ... -
Biofiltration in Drinking Water Treatment: Reduction of Membrane Fouling and Biodegradation of Organic Trace Contaminants
(University of Waterloo, 2010-02-17)The goal of drinking water treatment is to produce and deliver safe water to the consumers. To achieve these objectives water treatment plants are designed based on the concept of the multibarrier approach which combines ... -
Biofiltration-based “green technology” as a techno-ecological nature-based solution for drinking water treatment and climate change resilience
(University of Waterloo, 2022-06-02)While drinking water treatment process design is based on current and anticipated source water quality, changing climate makes it increasingly difficult to anticipate drinking water source quality and treatability. Although ... -
Biogeochemical Hotspots: Role of Small Water Bodies in Landscape Nutrient Processing
(University of Waterloo, 2017-05-09)Increased loading of nitrogen and phosphorus from agricultural and urban intensification has led to severe degradation of inland and coastal waters. Lakes, reservoirs, wetlands, and streams retain and transform these ... -
Biogeochemical Signatures of the Great Lakes Watersheds
(University of Waterloo, 2018-08-21)Water quality in many regions of the Great Lakes Basin (GLB) has deteriorated due to numerous anthropogenic drivers, including increases in agricultural area, increased fertilizer use, intensive livestock production, and ... -
Biogeochemistry Across Spatiotemporal Scales: The Role of Reactive Interfaces in Modulating Landscape Scale Contaminant Fluxes
(University of Waterloo, 2022-09-09)The intensification of agricultural and urban activities has been accompanied by increased fluxes of nutrients to inland and coastal waters, leading to concerns of eutrophication and drinking water contamination. Certain ... -
Biologically Active Filtration Media Properties: Practical and Mechanistic Implications
(University of Waterloo, 2017-01-16)Biologically active filtration [BAF] can be used to concurrently remove particles and natural organic matter during drinking water treatment. The selection of a given media type for use in BAF can impact filter performance, ... -
The Biomechanics of Mammary Epithelial Morphogenesis
(University of Waterloo, 2017-04-28)Major organs and tissues such as the lung, kidney, liver, and the salivary and mammary glands are complex structures, but share a fundamental building block – epithelial cells. During tissue formation – a process known as ... -
BOM removal by biofiltration- Developing a quantitative basis for comparison
(University of Waterloo, 2010-06-16)Biological filtration (Biofiltration) processes have been used first in Europe and then in North America for decades, however currently there is not a good overall parameter to guide biofiltration design and operation ... -
Bond and Development Length in Concrete Beams with Exposed Reinforcement
(University of Waterloo, 2013-09-19)Corrosion of steel reinforcement in Ontario bridges is causing severe soffit spalling in many situations. These spalled areas are often located within the lap splices and curtailment zones of the primary reinforcement. ... -
Bond and Flexural Behaviour of Self Consolidating Concrete Beams Reinforced and Prestressed with FRP Bars
(University of Waterloo, 2013-04-29)Self consolidating concrete (SCC) is widely used in the construction industry. SCC is a high performance concrete with high workability and consistency allowing it to flow under its own weight without vibration and making ... -
Bond Behaviour of Beams Reinforced with Near Surface Mounted Carbon Fibre Reinforced Polymer Rods under Fatigue Loading
(University of Waterloo, 2011-04-19)Over the past decade, extensive research has been conducted on the strengthening of reinforced concrete (RC) structures using externally bonded fibre reinforced polymer (FRP). More recently, near-surface mounted (NSM) FRP ... -
Bond Behaviour of Concrete Beams with Glass Fibre Reinforced Polymer Bars Under Fatigue Loading
(University of Waterloo, 2019-01-17)Since the 1980s and after the aerospace industries faced several periods of economic difficulty, the companies that produced fibre-reinforced polymers (FRPs) started to introduce them as new materials for construction ... -
Bond Behaviour of Corroded and CFRP Repaired RC Beams Subjected to Monotonic and Repeated Loading
(University of Waterloo, 2012-09-27)All reinforced concrete (RC) design theories are based on the assumption that concrete exhibits a perfect bond with the steel reinforcement. The bond between steel and concrete is essential to the transfer of the load ... -
Bond of Corroded Reinforcement in Partial Depth Repairs in Reinforced Concrete Elements
(University of Waterloo, 2017-08-29)The bond in a reinforcement concrete (RC) structure is represented by the force transfer between the reinforcing bar and the surrounding concrete. All the RC structures are designed to have a perfect bond between the ... -
Boundary Integral Equation Method in Elasticity with Microstructure
(University of Waterloo, 2006)Problems involving mechanical behavior of materials with microstructure are receiving an increasing amount of attention in the literature. First of all, it can be attributed to the fact that a number of recent experiments ... -
