Reactive Thin Film Polymers And Thin Film Composite Membranes For The Rapid Screening Of Uranium Isotopes, Abenazer W. Darge May 2022

Reactive Thin Film Polymers And Thin Film Composite Membranes For The Rapid Screening Of Uranium Isotopes, Abenazer W. Darge

All Dissertations

Traditional radiochemistry approaches for the detection of trace-level alpha-emitting radioisotopes in water require lengthy offsite sample preparations and do not lend themselves to rapid quantification. Therefore, a novel platform is needed that combines onsite purification, concentration, and isotopic screening with a fieldable detection system. My dissertation research objective was to develop novel reactive thin polymer films and thin film composite membranes for the selective separation of uranium from environmental water followed by direct isotopic analysis by alpha spectroscopy. Chapter 1 reviews progress made on uranium separation from aqueous matrices and discusses methods used for the determination of isotopic composition.

Flow Characteristics Through Granular Soil Influenced By Saline Water Intrusion: A Laboratory Investigation, Sudip Basack, Ghritartha Goswami, Hadi Khabbaz, M Karakouzian May 2022

Flow Characteristics Through Granular Soil Influenced By Saline Water Intrusion: A Laboratory Investigation, Sudip Basack, Ghritartha Goswami, Hadi Khabbaz, M Karakouzian

Civil and Environmental Engineering and Construction Faculty Research

The coastal geoenvironment initiates saline water intrusion into the freshwater aquifers, producing a geohydraulic problem. Such intrusion not only contaminates the fresh groundwater resources, making them unsuitable for human use, but also alters the hydraulic conductivity of the aquifer materials, which affects the coastal groundwater flow, influencing the water resources planning and management. Past investigations reveal that the groundwater flow can be linear or nonlinear depending upon the hydraulic gradient. Thus, the coefficients of nonlinear hydraulic conductivities are affected by saltwater intrusion. The present study focuses on an in-depth laboratory investigation into the influence of saltwater submergence on the nonlinear …

(2014). These higher summer temperatures will “increase electricity use, causing higher summer peak loads” as well as “pose physical and mental health challenges…outdoor …


The Effects Of Human Activity On Reintroduced Bighorn Sheep (Ovis Canadensis) Populations, Justine Cherovsky May 2022

The Effects Of Human Activity On Reintroduced Bighorn Sheep (Ovis Canadensis) Populations, Justine Cherovsky

Department of Environmental Studies: Undergraduate Student Theses

Since the decimation of North America’s bighorn sheep (Ovis canadensis) populations due to human impacts, translocations have been the primary conservation strategy to repopulate the native habitat. Following the extirpation of the species in Nebraska, bighorns were reintroduced with the hope to establish a stable population, but nearly four decades of management has resulted in large-scale die-offs and unstable herds. Ongoing human impacts have created similar results across the country as reintroductions struggle to establish independent bighorn herds. A systematic literature review was conducted to analyze current human related effects, evaluate the effectiveness of management practices, and compare these findings …

How Can Stakeholders In Food Sovereignty Achieve More Political Power?, Micah Dierks May 2022

How Can Stakeholders In Food Sovereignty Achieve More Political Power?, Micah Dierks

Department of Environmental Studies: Undergraduate Student Theses

Food sovereignty (FSv) is a peasant-driven, transnational movement that emerged in response to land-grabbing and the consolidation of power in food production. It advocates for the rights of people to define their own food practices and systems. To provide targeted feedback for movement reflexivity, 21 ecological conflicts referencing food sovereignty were sampled from the Global Atlas of Environmental Justice (the EJAtlas). Involved groups of actors and their forms of mobilization were correlated with interpretations of success from the EJAtlas. I recommend that stakeholders in food sovereignty pursue the acquisition of greater political power through improving messaging, leveraging or disrupting existing …

Assessing Urban Canopy Program In Redlands California, Joseph Angel Rocha Iv

Electronic Theses, Projects, and Dissertations

Climate change can cause major environmental and human health issues especially in lower income and minority communities (Ros et al. 2020; Bethel et al. 2022). Although studies note tree coverage alone cannot solve all climate related problems (Pataki, et al. 2021; Ross, 2021), tree coverage does provide alleviation for climate change related factors (Free-Smith, et al. 2004). Some ways trees can combat climate change is through improved air quality, improved water quality, and decreasing impacts of Urban Heat Island Effect (UHIE) (Nowak et al. 2018; Liu, Liu, 2021; Wang, Zhao, et al 2017). Although throughout the United States there is …

Department of Political Science: Faculty Publications

Early definitions of conservation focused largely on the end goals of protection or restoration of nature, and the various disciplinary domains that contribute to these ends. Conservation science and practice has evolved beyond being focused on just issues of scarcity and biodiversity decline. To better recognize the inherent links between human behaviour and conservation, “success” in conservation is now being defined in terms that include human rights and needs. We also know that who engages in conservation, and how, dictates the likelihood that conservation science will be embraced and applied to yield conservation gains. Here we present ideas for reconceptualizing …
