Zhang, Yu (2013-12)This dissertation advanced the traditional hydrological prediction via multi-sensor satellite remote sensing products, numerical weather forecasts and advanced data assimilation approach in sparsely gauged or even ungauged ... -
Dialogue as a Foundation for Development: Syrian Collective Trauma and Memory, Actor Mapping, and Perspectives on Syria
Kroeger, Anne (2017-05)In 1949, President Harry S. Truman called upon the global North to aid the “underdeveloped” global South. With Truman’s “Point Four” declaration, the United States sought to combat the rising threat of communism with ... -
Educated Decision-Makers are Harder to Bias: Comparing Education and Nudges on Reliable Deliberation about Recycled Water
Tanner, Braden (2023-08)Recently, it has become important to define ethical rules governing the most appropriate ways to interact with those that decision interventions seek to influence. However, philosophical theories and current methods of ... -
The Effects of Evaporation and Capillary Forces on Fluid Motion, Solute Transport, and Water Content From the Grain Scale to the Continuum Scale in Unsaturated Porous Media
Adegbule, Aderonke (2019)This work aimed to explore how fluid motion, solute transport, and water content are influenced by evaporation and capillary forces in unsaturated porous media, across a range of scales. Experiments were conducted from the ... -
THE EFFECTS OF RANDOM AND CONTROLLED LATERAL CONFINEMENT ON SURFACTANT ADSORPTION
Hamon, Joshua Jacob (2018-07-31)Abstract The effects of temperature and surface roughness on the mass and viscoelasticity of an adsorbed surfactant layer were monitored using the quartz crystal microbalance with dissipation (QCM-D). Adsorption isotherms ... -
Encapsulated thrombolytic microspheres to prevent reocclusion after thrombolysis and triggered release microspheres to deliver therapeutic drugs
Nguyen, Hoai (2015)Cardiovascular diseases, including acute myocardial infarction, stroke, peripheral arterial diseases, and pulmonary embolism, are the most common and growing cause of morbidity and mortality in the United States. Early ... -
FISCHER-TROPSCH SYNTHESIS ON HYDROPHOBIC CATALYSTS IN BIPHASIC MEDIA
