Sustainability Of Water And Wastewater Infrastructure: Using A Public-Private Partnership Model For Project Financial Assessment, Rebecca Werner Trotter
Sustainability Of Water And Wastewater Infrastructure: Using A Public-Private Partnership Model For Project Financial Assessment, Rebecca Werner Trotter
Electronic Theses and Dissertations
To supplement current and future budget shortfalls for improvements to water and wastewater infrastructure, Public-Private Partnerships (PPPs or P3) are being advocated by the American Society of Civil Engineers (ASCE) and others as a practical mechanism to ensure financial sustainability. A PPP involves a partnership between a government entity and a concessionaire--consisting of one or more private companies acting as a single, private incorporation--who make an agreement on funding, building, and operating a usually government-provided service, such as drinking water and wastewater infrastructure. This is different from a traditional contract between a government entity and a contractor because the concessionaire …
The Effect Of Static Pressure On The Inertial Cavitation Threshold And Collapse Strength, Kenneth Bryan Bader
The Effect Of Static Pressure On The Inertial Cavitation Threshold And Collapse Strength, Kenneth Bryan Bader
Electronic Theses and Dissertations
The amplitude of the acoustic pressure required to nucleate a gas and/or vapor bubble in a fluid, and to have that bubble undergo an inertial collapse, is termed the inertial cavitation threshold. The hydrostatic dependence of the inertial cavitation threshold was measured up to 30 MPa in ultrapure water using a high quality factor spherical resonator. The threshold increased linearly with the hydrostatic pressure and was found to be temperature dependent. The strength of the bubble collapse at the threshold was measured in terms of shock waves and light emissions. The shock amplitudes increased linearly with the hydrostatic pressure, while …
