Dental Cement Thickening Agents For Mudslide Prevention, Kristina Emiliya Babayev, Emily Elizabeth Johnson, Diana Evet Reihaneh

Materials Engineering

The purpose of this project is to develop a non-toxic mud thickening agent for the application of decreasing mudslide intensity where performance is measured by flow rate, viscosity, and toxicity tests. We hypothesized that dental cements could be a potential candidate due to their adhesive, hydrophilic, and biocompatible properties. Zinc phosphate, glass ionomer, and polycarboxylate cement were among the dental cements tested. These tests were performed at low and high concentrations of 25 grams and 125 grams, respectively, mixed into soil to produce 3500 gram samples. The dental cements produced noticeable thickening effects in the mud, as the average viscosity …

Characterization Of Landslide Processes From Radar Remote Sensing And Hydromechanical Modeling, Yuankun Xu

Earth Sciences Theses and Dissertations

Landsides are a natural geomorphic process yet a dangerous hazard which annually causes thousands of casualties and billions of property loss in a global scale. Understanding landslide motion kinematics from early initiation to final deposition is critical for monitoring, assessing, and forecasting landslide movement in order to mitigate their hazards. Landslides occur under diverse environmental settings and appear in variable types; however, all types of landslides can be mechanically attributed to shearing failure at the basal surface due to stress regime shift contributed by internal and/or external forcing. Typical internal factors include soil/rock weathering, whereas typical external triggering forces encompass …
