Environmental Justice Issues And Sea Level Rise In Frontline Communties Along The Gulf Coast, Karla Michel Lopez
Open Access Theses & Dissertations
Sea level rise poses a great threat to coastal areas and our way of life. As flooding increases in frequency and intensity across the country, vulnerable populations become a target to its impacts. The U.S. dedicates much research to risk communication and climate change adaptation strategies; however, these coastal areas are home to a large percentage of underserved and underrepresented communities that can be challenging to meaningfully engage. The impacts of short-term sea level rise combined with long-term sea level rise will not only cause flooding, erosion, and intrusion of saltwater into freshwater resources but also increased financial consequences, such …
Synthesis, Characterization, And Direct-Ink-Writing Of Syntactic Foams, Andrea Irigoyen
Synthesis, Characterization, And Direct-Ink-Writing Of Syntactic Foams, Andrea Irigoyen
Open Access Theses & Dissertations
This project encompasses three different methods to fabricate syntactic foams using a PDMS matrix i.e., hollow spheres inclusion, pore generator leaching by solvent, and emulsion. The foam formation by using polysiloxane hollow spheres is done in a 3-step process. The first step is to create a core of polystyrene following a dispersion polymerization process. The goal for the size of the pore is to monodisperse and have an average diameter of 5-10 ÃÂüm, so the polystyrene core must be as well within that range. After that, the cores are coated with a polysiloxane shell by following a polymerization by condensation …
Environmental Dynamics: A Compendium Of Rhetorical Application, Annalisa Perez
Environmental Dynamics: A Compendium Of Rhetorical Application, Annalisa Perez
Open Access Theses & Dissertations
Technology, albeit exceedingly useful, has exponentially exacerbated the communications dilemma between the technical and the non-technical. Additionally, based on a current new understanding of the term environmental, it can no longer be fully defined by terms such as air, water, waste, or purification. Rather, the meaning of environmental has been globally transformed in several ways. The term environmental is encompassing an expansion of understanding and is further defined with words such as essence, perception, rapport and multi-dimensional spaces. This work, Environmental Dynamics: A Compendium of Rhetorical Application (EDC), provides a framework where communication can be enhanced in areas where communication …

Design And Evaluation Of The Impact Of A Multi-Agent Control System (Framework) Applied To A Social Setting, Perez Antonio Perez
Open Access Theses & Dissertations
The objective of this research is to design and analyze the performance of a new mechanism to improve the advising of students in a nontraditional environment. This nontraditional environment includes: a minority serving, commuter campus with a high percentage of transfer students. Specifically, these demographics are unable to keep a tightly controlled cohort of students flowing through to the completion of the curriculum. Students in these circumstances usually have varied course loads and competing priorities due to family and financial needs or other societal responsibilities. Therefore, there is a need for an individualized approach to advising.
University administrations face challenges …
Printable Biodegradable Hydrogel For Skin Wound Dressing Using Inkjet Printing Technology, Maria G. Yanez
Printable Biodegradable Hydrogel For Skin Wound Dressing Using Inkjet Printing Technology, Maria G. Yanez
Open Access Theses & Dissertations
Chronic wounds are becoming more frequent. Foot ulcers affect approximately 10% - 15% of patients with diabetes throughout their lifetimes, and by 2025, it is estimated the prevalence of diabetes will be 250 million people in the worldwide. There is increased potential for patients with peripheral neuropathy and peripheral vascular disease to suffer more foot injuries. These conditions reduce the normal pain sensations and healing of minor traumas, allowing the development of chronic non-healing ulcers, often preceding lower-extremity amputation. These types of wounds are very difficult to treat and sometimes take months or even years to heal because of many …
