Effects of clay-water interactions on water retention in porous media

Creator:: Lenhard, Robert J. (Robert James)
Abstract:: Capillary pressure-saturation data obtained for unconsolidated porous media with different liquids are examined to investigate the effects of clay-liquid interactions on liquid retention. Liquid retention functions are assumed to reflect the effective pore-size distributions. The hydraulic variables, capillary pressure and saturation, are transformed to account for changes in liquid retention...

Annual Costs of Wild Salmon Restoration Efforts in the Columbia River Basin

Creator:: Rice, Robert J.
Abstract:: The goal of this project was to estimate the total annual cost of salmon recovery efforts throughout the Columbia River Basin from all stakeholders, including direct and indirect costs. How much is spent on salmon recovery efforts each year in the Columbia River Basin? Depending on who you ask, you...

Segregation in Public Schools Through the Lens of Tiebout Theory: A case study of Oregon's open enrollment policy

Creator:: Backus, Robert J.
Abstract:: In 2011 Oregon enacted a public education open enrollment policy that gives students and families the choice of what school to attend, regardless of district lines. Despite the lack of public information, this policy will sunset this school year unless it is further extended during legislative session. This paper attempts...

In vivo Reactions of Tetrazines Incorporated through Genetic Code Expansion

Creator:: Blizzard, Robert J.
Abstract:: The inverse electron demand Diels Alder reaction between tetrazines and strained alkenes is an exceptionally useful tool in functionalizing to biomolecules since it is orthogonal to the chemistry of most living systems and have exceptionally high rate constants. In particular reactions between strained trans-cyclooctenes (sTCO) and tetrazines can achieve second...

Engineering a Profiling System for a Robotic Oceanographic Surface Sampler

Creator:: Shannon, Robert J.
Abstract:: ROSS (Robotic Oceanographic Surface Sampler) is an autonomous boat, equipped with oceanographic sensors, used for studying the ocean’s surface. One of its advantages over traditional research vessels is its ability to sample near glaciers, an area too dangerous for manned ships. In order to properly ascertain deep ocean heat’s effect...

Realized and potential climate responses of lichen and bryophyte communities in a national forest inventory

Creator:: Smith, Robert J.
Abstract:: Climate and terrestrial vegetation have had mutual feedbacks for nearly five hundred million years, yet both are now departing from recent historical norms, with uncertain implications for forest ecosystems. This dissertation outlines the current and potential future climate responses of lichen and bryophyte communities in the United States as part...

Early Predictors of Academic Achievement and Externalizing Problems for Children in Low-Income Families

Creator:: Duncan, Robert J.
Abstract:: Empirical studies and theory have identified many early predictors of children's academic achievement and externalizing problems. Moreover, research shows that children's early cognitive abilities and behavioral problems are strong predictors of later academic achievement and externalizing problems. The current dissertation studies extend previous work and unpack how early predictors relate...
