Grassland Restoration and Climate Change: Altar Valley, Arizona Case Study

Creator:: Gondor, Anne
Abstract:: The Altar Valley is an important working landscape that supports biodiversity and vulnerable species in Pima County, Arizona (Huckelberry 2000). This semi-desert grassland, alluvial valley and 713,807-acre watershed composed of 39 subbasins serves as an aquifer to a portion of southwestern Tucson. This region of Southern Arizona has been identified...

Timescales and tectonics of oceanic plateaus : long-term evolution of Ontong Java Nui and Rio Grande Rise

Creator:: Davidson, Peter C.
Abstract:: Oceanic plateaus are regions of overthickened oceanic crust and are often thought to form from the interaction of mantle plumes with oceanic lithosphere. These regions can cover vast areas of the ocean basins and represent a highly elevated magmatic flux relative to normal mid-ocean ridge spreading. Oceanic plateaus are considered...

Design and Analysis of Free-space Optical Communications Systems for Next Generation Short-range Wireless Networks

Creator:: Liverman, Spencer
Abstract:: This dissertation focuses on indoor free-space optical communications systems for use in short range wireless networks. We propose that current radio frequency wireless links be augmented or replaced with optical frequency links due to overcrowding in the radio frequency spectrum. Optical frequencies contain hundreds of terahertz of unregulated bandwidth and...

New Treatments for HIV and Cancer: Uncovering Bioactive Compounds from Small Molecule Sources

Creator:: Overacker, Ross D.
Abstract:: Small molecule drugs have been instrumental in our fight against diseases, beginning when some of the earliest ancient cultures used plant remedies to treat illnesses. More recently, the skill of isolating and characterizing the active ingredients within bioactive plants and microbial extracts has led to the isolation and design of...

The Feminist Itinerant School: A Feminist Pedagogical Approach to Curriculum Transformation for Public School Teachers in Brazil

Creator:: Melchor, Carolina R.
Abstract:: This Thesis examines Brazil’s political and historical context to explore and understand the logics behind the high rates of violence in our society. It focuses in education as one of our main vehicles of disseminating knowledge and therefore culture, language and values that might be contributing and perpetuating sexism, racism,...

Power Efficient Hybrid Architecture for High Resolution Analog-to-Digital Converters

Creator:: Zhang, Hui
Abstract:: Analog-to-digital converters (ADCs) are the key building block for sensor applications, such as wireless communications and digital electronics. These applications require ADCs to have medium to high accuracy (normally from 10-14 bits) and relatively low signal bandwidth (ranging from 100Hz-150kHz). Since these applications are often powered by batteries, high power...

Environmental Justice Inventory – Linn-Benton County, Oregon

Creator:: Patchell, Roman, Judokusumo, Madeline, Cortes, Mariana, and Fisher, Halle
Abstract:: The purpose of this inventory is to detail the state of environmental justice in the Mid- Willamette Valley in an up-to-date, centralized format. The inventory is based on information from various government sources, and a survey to gather first-person perspective to take a pulse of the wellbeing of our community....

Disputed Spaces : Concheras, Shrimp Aquaculture, and Conservation in the Mangrove Forests of Southern Esmeraldas, Ecuador

Creator:: Treviño Peña, Melva B.
Abstract:: The mangrove ecosystem has served as a life-support system to large populations of coastal dwellers in Ecuador for many generations. Diverse communities comprised of multi-racial and multi-ethnic groups have formed along the edge of the mangrove forests throughout the Ecuadorian coast. These groups self-identify as being part of an “ancestral”...

Early post-restoration recovery of tidal wetland structure and function at the Southern Flow Corridor project, Tillamook Bay, Oregon

Creator:: Janousek, Christopher, Bailey, Scott, van de Wetering, Stan, Brophy, Laura, Bridgham, Scott, Schultz, Matthew, and Tice-Lewis, Maxwell
Abstract:: A substantial fraction of estuarine tidal wetlands have been lost to development or other human uses in the Pacific Northwest since the 1800s. Wetland restoration, typically through tidal re-connection, can restore normal tidal hydrology to these areas and improve estuarine capacity to support ecosystem functions and services. Restoration may initiate...
