Exploring Regional And Telecoupled Land Use Change Impacts From Environmental Shocks, Kevin Hill, Liz Wachs, Brady Hardiman, David Yu, Shweta Singh
The Summer Undergraduate Research Fellowship (SURF) Symposium
Natural disasters or environmental shocks have the potential to disrupt local agricultural systems as well as distant agricultural systems through cascading effects. In this work we selected two distinct environmental shocks and traced their cascading effects on land use change. Quantifying cascading effects is a salient issue because climate change forecasts indicate an increase in frequency and intensity of global environmental shocks. This study incorporated the concept of telecoupled systems involving interrelating ecological, economic and political/social components. A telecoupled framework involving cascading effects was implemented using three approaches. The first approach involved using bilateral agricultural trade matrix data to analyze …
Comparative Life Cycle Assessment Of Direct And Indirect Solar Water Disinfection Processes In Developing Countries, Jason K. Hawes, Margaret M. Busse, Ernest R. Blatchley Iii
Comparative Life Cycle Assessment Of Direct And Indirect Solar Water Disinfection Processes In Developing Countries, Jason K. Hawes, Margaret M. Busse, Ernest R. Blatchley Iii
The Summer Undergraduate Research Fellowship (SURF) Symposium
In July 2010, the UN General Assembly recognized the universal human right to sufficient water for health and sanitation (UN…, 2010). The reliable disinfection of this water plays a critical role in public health (Carter and Miller, 2005), and this study investigates the use of four ultraviolet (UV) disinfection methods for use in international development and disaster relief. The study focuses on the life cycle impacts of four direct and indirect solar ultraviolet disinfection systems. Direct solar disinfection refers to exposure of water to solar radiation, while indirect solar disinfection collects solar energy and uses this to power a UV …
Pore Scale Transport Of Miscible And Immiscible Fluids In Porous Media, Tolulope O. Odimayomi, Arezoo M. Ardekani
Pore Scale Transport Of Miscible And Immiscible Fluids In Porous Media, Tolulope O. Odimayomi, Arezoo M. Ardekani
The Summer Undergraduate Research Fellowship (SURF) Symposium
The separation of harmful or valuable substances entrapped in porous media has applications in processes such as enhanced oil recovery, diffusion in tissue, and aquifer remediation. In this study the motion and removal rate of immiscible and miscible solutions have been analyzed to gain understanding of solvent effectiveness as it is diluted due to diffusion or mixing within porous materials. The extraction of oil using water, a surfactant solution of 4% CTAB in water, and a foam produced form the surfactant solution is observed using two dimensional flows between parallel slides containing cylindrical obstacles. The fluid motion is visualized. The …
Developing Methods To Characterize Cured-In-Place Pipe (Cipp), Emily N. Conkling, Mahboobeh Teimouri, Andrew Whelton
Developing Methods To Characterize Cured-In-Place Pipe (Cipp), Emily N. Conkling, Mahboobeh Teimouri, Andrew Whelton
The Summer Undergraduate Research Fellowship (SURF) Symposium
Cured-in-place pipe (CIPP) is quickly growing as a method to repair aging water pipes. It’s an attractive option for states’ Departments of Transportation, as CIPP doesn’t require any long term or invasive construction. The exact composition of CIPP is poorly understood, even though CIPP leaching is assumed to be the cause of algal blooms, fish kills, and some human illnesses. The goal of this study was to develop methods to characterize what chemicals are present in uncured and cured CIPP resin and at what magnitude. An exhaust capture system was designed, and the condensate collected from this was extracted using …
