X-ray computed tomography is a noninvasive imaging modality capable of reconstructing exact density values of 3D objects. Computed tomography machines are deployed across the world to provide doctors with an image that reveals more detail than a standard x-ray image. We investigate algorithms based on exact computed tomography reconstruction formulas...
Benthic foraminiferal δ¹³C data from site 502 in the Caribbean Sea (sill depth 1800 m) indicate that throughout the past 2.6 m.y., glacial δ¹³C values in the middepth Atlantic were higher during glaciations than interglaciations. This is interpreted as indicating a greater proportion of Upper North Atlantic Deep Water (UNADW)...
The adsorption equilibrium and kinetic behavior exhibited
by β-lactoglobulin at silanized silicon surfaces of varying
hydrophobicity were examined using ellipsometry. Adsorption
equilibrium results were used to construct adsorption
isotherms; the adsorbed mass of β-lactoglobulin was observed
to increase with increasing surface hydrophobicity, within a
defined range of hydrophobicity. Adsorption kinetics...
Ellipsometry was used to study the effects of surface energetics
and temperature on the equilibrium adsorptive behavior exhibited by
β-lactoglobulin. β-Lactoglobulin isotherms at 25, 37, and 55°C were
constructed for this purpose. The surfaces of acrylic, polycarbonate,
polyester, glass, and #304 stainless steel were contacted with protein
solutions of varying...
The slow β relaxation is understood to be a universal feature of glassy dynamics. Its presence in bulk metallic
glasses (BMGs) is evidence of a broad relaxation time spectrum that extends to deep within the glassy state.
Despite the breadth of research devoted to this phenomenon, its microscopic origin is...
The relative enrichment of skin sebaceous gland lipids with deuterium-labeled
α-tocopherol was compared with plasma enrichment to evaluate the
delivery of vitamin E to skin. For the first week of this study, each subject
consumed a daily dose of deuterated vitamin E (150 mg of an equimolar mixture of
BACKGROUND: Little is known about α-tocopherol’s bioavailability
as a constituent of food or its dependence on a subject’s age.
OBJECTIVE: To evaluate the α-tocopherol bioavailability from food,
we used collard greens grown in deuterated water (²H collard
greens) as a source of deuterium-labeled (²H) α-tocopherol consumed
by younger and older...
What does comida rica mean? In this thesis, I explore the meanings of comida rica, sana, and de nuestra tierra through the discourses, practices, and kitchen geographies in six urban, highland households in the Ecuadorean Andes. This research, as part of a larger investigation carried out by a team of...
The purpose of this project was to investigate the roles of different languages (namely Guaraní, Jopará, and Spanish) in the formation of Paraguayan cultural identity among Paraguayan migrants to the greater Buenos Aires region of Argentina. Though the Paraguayan community makes up the largest immigrant population in Argentina, outside of...
From my personal experiences, I’ve noticed that Latinx students and families are most receptive to college-related information communicated as anecdotes. Latinx students are among the most poorly represented demographic at universities nationwide, which I believe can be mitigated through calculated efforts to increase collegiate literacy and understanding. This project is...
Juntos is a college and career readiness program that includes workshops and continuing education activities for Latino middle and high school students and their families. The Columbia Gorge Juntos Program began last year in partnership with the K-12 school districts and community college. Four middle schools implemented the program with...
Zora Neale Hurston was a Black American writer
during the period of the Harlem Renaissance. The
purpose of this study is to show that three of her four
novels form a protracted discussion of a particular
type of freedom which was of especial interest to
Hurston. The study seeks to...
The marine climate of the Galapagos is spatially and seasonally
heterogeneous. A taxonomically comprehensive study of Galapagos zooplankton has
never been done. This study is an initial effort to establish the distribution and
community structure of zooplankton in the Archipelago. I collected zooplankton
samples by vertical tows over the Galapagos...
Samples targeting crustacean zooplankton were collected from 3 upper Willamette Basin reservoirs during May-August 2015. Van Dorn sampling devices were used to collect samples at discrete depths from Fall Creek Reservoir, Lookout Point Reservoir, and Hills Creek Reservoir.
Zooplankton samples were collected during daytime and nighttime corresponding with the new...
This technical report summarizes the
results of a three year study of the zooplankton
living in the nearshore zone off
Newport, Oregon. The sampling program was
part of the Early Life History (ELH) project
of the Oregon State University Sea Grant Program
and was designed to study the ecology
