This thesis examines food insecurity in Oregon among food bank users over the course of The Great Recession. Analyzing data from the Oregon Food Bank, this thesis tells the story of the change that the recession brought upon low-income families. In examining the regional differences in food insecurity, the local...
An Achilles tendon injury can be devastating. Surgical methods to bring the muscle to full strength are not always available. Proposed is an ankle foot orthosis (AFO) that is entirely passive (does not add energy to the system) and uses the mechanical advantages provided by the walking gait of a...
Dissolved organic carbon (DOC) flux is an important mechanism to convey soil carbon (C) from aboveground organic debris (litter) to deeper soil horizons and can influence the formation of stable soil organic carbon (SOC) compounds. Aboveground litter quantity and quality was manipulated for 20-years in an old-growth Douglas fir forest...
When my mother’s mother sent her over to the new, western world, she sent her with a suitcase full of spices you couldn’t find at an American grocery store in the 90’s: tamarind and turmeric, coriander root and cumin. Ammu, my mother, had truly packed her entire life and everything...
We live in a world today where it doesn’t come as a surprise to hear about another girl being roofied at a college party, nor is it shocking to find out about how your friend was sexually harassed by an older man at work. Women are taught how to avoid...
Metal-Organic Frameworks (MOFs) are crystalline compounds formed from reacting a metal ion with an organic ligand. They represent a promising new avenue in materials science for gas separations and storage. Certain MOFs, in particular Mg-MOF-74, have shown a strong affinity for the capture of CO2. This project investigated a known...
Understanding how particles behave in detectors is a critical part of analyzing data from neutrino experiments. There are methods in place to track charged particles in scintillator material, but neutral particles such as neutrons are more difficult to characterize. The purpose of this project was to assess and calibrate methods...
Thin films of the p-type semiconductor, barium copper sulfide fluoride (BaCuSF) were deposited using pulsed laser deposition. Similar p-type conductivity in Cu2O is caused by copper vacancies. Addition of copper dopant is proposed as a method for filling the copper vacancies in BaCuSF. The films are characterized to determine quality...
Introduction Over the past century, great technological advances have enabled high-speed communication and transportation across the globe. This technology trend combined with the needs of continuous expansion of market place has motivated major corporations not to restrict their business activities to within a single principality. Engineering design activities can take...
