The Effects of Biofilm on Sandy Soil Hydrology

Creator:: Runion, Danielle N.
Abstract:: It is known that soil biota affects water dynamics through various complex mechanisms. The impact on retention by soil biota are due to a combination of changes to pore geometry, pore clogging by biofilms, biofilms that serve to connect thin water films across many pores as the soil dries, and...

Approaches for Characterizing Plant Physiological Responses to Environmental Stress

Creator:: Marias, Danielle E.
Abstract:: It is uncertain how predicted changes in climate will impact vegetation responses and plant species’ distributions because the physiological mechanisms underlying thresholds for damage are not well understood, and responses to stress vary by functional type and developmental stage. Thus, it is crucial to investigate physiological responses to heat and...

Impacts of dwarf mistletoe on the physiology of host Tsuga heterophylla trees as recorded in tree ring C and O stable isotopes

Creator:: Marias, Danielle E.
Abstract:: Dwarf mistletoes, obligate, parasitic plants with diminutive aerial shoots, have long-term effects on host tree water relations, hydraulic architecture, and photosynthetic gas exchange and can eventually lead to tree death. To investigate the long-term impacts of dwarf mistletoe on gas exchange of host western hemlock trees, I compared growth, gas...

Flow processes in the dry regime : the effect on capillary barrier performance

Creator:: Jansik, Danielle P.
Abstract:: Engineered capillary barriers typically consist of two layers of granular materials designed so that the contrast in sediment hydrologic properties and sloping interface retains infiltrating water in the upper layer. We report here on the results of two bench-top capillary barrier experiments, and associated modeling. These experiments were conducted to...

Maria Susanna Cummins' "The Lamplighter" : a revisioning of a sentimental writer of the nineteenth-century United States as rhetor, social critic, and feminist

Creator:: Steinert, Laura
Abstract:: Within The Lamplighter, a novel written in 1854, Maria Susanna Cummins defines a version of the sentimental novel that significantly differs from the prescriptive analysis male critics have offered for the genre. This thesis argues that feminist theory and recent rhetorical theory have caused a critical paradigm shift that has...

Plot-Scale Field Investigation : Characterizing Water Motion in Sandy Agricultural Soils

Creator:: Nolasco, Stephanie M.
Abstract:: Irrigated agricultural production in sandy soils presents several unique challenges to growers, including naturally high permeability, low native water retention, as well as high rates of water drainage losses and leaching of chemicals to the shallow aquifers. This study is an initial investigation into water motion in the sandy agricultural...

Migration of E. coli and solutes to tile drains via preferential and matrix flow

Creator:: Moreno, Daniel
Abstract:: The extent of agricultural drainage has created concern for its potential undesirable effects on surface water quality. Land applications of liquid manure on tile drain fields have the potential to transport solutes and bacteria to the drains following precipitation or irrigation events and many times are directly sent to a...

Assessing Managed Aquifer Recharge Potential: Regional to Local Evaluation

Creator:: Gibson, Maria
Abstract:: Although surface water constitutes less than 1.5% of freshwater supply, historical development of surface water sources continues to mark the landscape. However, over- exploitation of groundwater is now at its highest, and 25% of the world’s 1.7 billion population live in water scare regions. As glaciers and snowpack disappear due...

User Interface and Database for the Intuitive, Developmental And Research Oriented, Easy To Use, Affordable, And Low Volume (IDEAL) Bioreactor

Creator:: Litzinger, Jaelyn W.
Abstract:: Expensive pricing for laboratory bioreactors proves to be the main barrier-to-entry for lab-scale academic research. Most laboratory bioreactors are priced at $100K+ and require significant training to use, thereby limiting their accessibility. The IDEAL (Intuitive, Developmental And Research Oriented, Easy To Use, Affordable, And Low Volume) Bioreactor aims to solve...

How crabs walk and what can robots learn from it?

Creator:: Shen, Nuocheng
Abstract:: Simulation has provided much design inspiration for the field of robotics. While many astute ideas can be computationally formulated, there are some good structures in animals that people call “biologically-inspired”. Many robots are designed based on natural creatures such as crabs, spiders, etc. Before we can take full advantage of...
