Wastewater Refining And Reuse And City-Level Water Decision Making, Ahmed Abuhussein

Electronic Thesis and Dissertation Repository

Direct discharge of treated and untreated wastewater to natural surface water bodies, including rivers and lakes, is generally known to produce adverse environmental impacts that have been of concern for the past 10–15 years, particularly in the Great Lakes basin. Examples of these impacts include eutrophication and the emergence of pharmaceuticals and personal care products (PPCPs). Advancement in wastewater treatment plant operations alone may not be feasible to meet the 2016–2019 Federal Sustainable Development Strategy (FSDS), especially on phosphorus reduction targets. Diverting treated wastewater to land could present a multibarrier approach for integrated PPCPs management, and could also shift current …

Tensile And Impact Behaviour Of Shape Memory Alloy Fibre Reinforced Engineered Cementitious Composites, Mohamed Ali El-Sayed Mahmoud Ali

Electronic Thesis and Dissertation Repository

Extreme loading events such as impact, blast, and earthquakes have often led to partial or total collapse of structures, associated with economic and human life loss. Therefore, civil engineers have been seeking innovative materials and systems that would allow designing resilient and smart structures which can withstand such catastrophic events. Recently, engineered cementitious composites (ECC) and shape memory alloys (SMA) have emerged as strong contenders in the production of smart and resilient structural systems.

The aims of this study are to explore the possible synergy between ECC and SMA for developing a novel hybrid fibre-reinforced ECC incorporating randomly dispersed SMA …

Development And Assessment Of An Impact Apparatus And High-Speed Camera Motion Tracking System To Quantify The Effect Of Static Muscle Loads On Fracture Threshold Measures In The Distal Radius, Jacob M. Reeves

Electronic Thesis and Dissertation Repository

Distal radius fractures are prevalent, debilitating, and costly. This thesis conducts an in vitro investigation of these injuries, examining the role of static muscle loading on fracture threshold measures (i.e., force, impulse, energy). Initially, an impact apparatus and custom LabVIEW colour-thresholding program were designed and assessed for repeatability and accuracy in quantifying fracture measures and impact kinematics. These tools were then used to test six pairs of cadaveric forearms, with static muscle loads simulated in one specimen from each pair. Distal radius fractures were achieved in 5 pairs, with perilunate dislocations in the remaining pair. None of the …
