Effect of Biofiltration on DBP Formation at Full-Scale and Pilot-Scale
(University of Waterloo, 2008-01-25)Over the past century chlorine has been a reliable disinfectant to reduce transmission of waterborne diseases in drinking water. Concerns about chlorination have increased since it was discovered in the 1970s that use of ... -
Effect of Bridge Geometry on Seam Weld Microstructures in AA6xxx Aluminum Porthole Die Extrusions
(University of Waterloo, 2020-05-27)A series of porthole die extrusion trials were conducted with AA6xxx aluminum alloys to understand the influence of die geometry (bridge shape and welding chamber height), extrusion process parameters (ram speed) on the ... -
Effect of Buffer on Protein Capture with Weak Cation Exchange Membranes
(University of Waterloo, 2015-08-26)Ion exchange membrane chromatography represents a potential alternative to conventional Protein A or resin chromatography for protein capture of monoclonal antibodies (mAbs), due to its high throughput and low operation ... -
The Effect of Building Construction and HVAC Systems on PM Concentration from Outdoor Sources
(University of Waterloo, 2012-09-27)Adverse health effects of human exposure to particulate matter (PM) in indoor environments and the associated costs have been of interest in recent studies conducted outside Canada. It was, therefore, necessary to investigate ... -
The Effect of Canadian Tax Policy on Executive Equity Grants: Corporate Tax Planning and Managerial Power
(University of Waterloo, 2018-08-20)This study examines how the tax treatment of corporate tax-deductible restricted share units and employee tax-favoured stock options at the employer and employee level affect the extent of their use in executive equity ... -
Effect of Club Selection and Clubhead Speed on the Knee Joint during the Golf Swing
(University of Waterloo, 2018-05-23)Golf is a sport that can be played throughout one’s lifetime providing an opportunity for competition, socialization, and improved physical activity. Golf is commonly recommended by physicians to those with knee ailments, ... -
Effect of co-ions and counter-ions on mAb capture with weak cation exchange membranes
(University of Waterloo, 2020-01-20)Cation exchange chromatography (CEX) has risen as a promising alternative to Protein-A affinity chromatography for the capture of monoclonal antibody (mAb). mAb capture with CEX works on the basis of electrostatic interactions ... -
The Effect of Coarse Gravel on Cohesive Sediment Entrapment in an Annular Flume
(University of Waterloo, 2014-03-07)The amount and type of cohesive sediment found in gravel river beds can have important implications for the health of aquatic biota, surface/groundwater interactions and water quality. Due to landscape disturbances in the ... -
The Effect of Cold Spray Coating on Fatigue Life of Magnesium Alloy, AZ31B
(University of Waterloo, 2011-10-27)Wrought magnesium alloys are considered attractive candidates for structural members in automotive and aerospace industries due to their high specific strength. Although new processes have helped to produce high purity ... -
The effect of cold spray coating parameters on the residual stress and fatigue performance of magnesium alloys
(University of Waterloo, 2020-02-14)Global warming, dwindling fossil fuels, and the low efficiency of alternative energy sources such as batteries and solar panels compared to traditional carbon-based energy sources, have shifted the industrial design paradigm ... -
