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...
In the Columbia Basin, pre-plant soil fumigation is commonly used in potato production for pest control, but fumigation can kill non-target organisms within the soil, result in unintended shifts in the microbial community, and disrupt long-term soil health. Cover crops have been shown to strongly influence the numbers and communities...
As mass-timber building construction rises around the globe, there exists the need to verify the long-term, in-situ behavior and performance of these structural systems. Structural health monitoring (SHM), generally defined as a damage detection strategy consisting of a network of sensors, a data acquisition system, and algorithms for data analysis,...
Oxidative stress that occurs during cryopreservation may be reduced by the addition of antioxidants. Vitamin E (Vit E), Vitamin C (Vit C), glutathione (GSH), lipoic acid (LA), glycine betaine (GB) and polyvinylpyrrolidone (PVP) were applied at four steps of the PVS2 vitrification protocol (pretreatment, loading, rinsing, and regrowth). Shoot tips...

American Literature, previous to the Civil War, is
of necessity confined closely to the writers and writings
of New England and New York. At present however a gradual widening of the literary field may be clearly discernible. The South and West now contribute their share,
and no one can truly...
The peppermint industry is the largest commercial herb industry
in the United States. Oregon is the largest peppermint producing
state with nearly 60 percent of the total United States peppermint
oil production. There is a need for economic information about current
and future prospects for the national peppermint industry as...
Optimal commercial fishery management sustains each salmon species' population while maximizing economic benefits. This thesis addresses two questions. What are the Alaska Department of Fish and Game's and the Board of Fisheries' intentions when conducting a fishery management plan in Upper Cook Inlet? How does it compare to its implementation?...
Urban centers, in part, are in the process of deterioration. Consequently, land values in these areas, both in dollars and in contribution to the community, remain dormant or depressed. There seems little doubt that there will be greater pressure for urban land. Urban renewal is one method of returning deteriorated...
A cost reduction analysis is performed by coordinating
the exchange of LANDSAT (formerly ERTS) data between a CDC
3300 and a PDP8/L minicomputer. The LANDSAT data is displayed
on a 4002 Tektronix terminal by means of a grayscale output.
Large amounts of data and number manipulation are processed
in the...
Soil column studies were performed on a chromium contaminated soil from the United
Chrome Products Superfund Site currently undergoing a pump-and-treat cleanup process. The
goal of the research was to provide insight into the feasibility of chemically changing the injection
fluid of the pump-and-treat system to enhance hexavalent chromium (Cr(VI))...
The objectives of this study were to 1) measure and compare the compositional differences of essential oil among three hop cultivars ('Centennial’, 'Citra' and 'Nelson Sauvin'), 2) identify the odor-active aroma compounds in three varieties of hops and 3) investigate the behavior of hop-derived aroma compounds in beers prepared by...
Ranchers in the high desert area of Eastern Oregon traditionally
market their calves when they are weaned in late fall.
This is the time when the market prices for calves are at a
seasonal low.
In this study the economic feasibility of various alternative
management and marketing strategies for the...
Sediments are the major compartment in aquatic environments for many materials of toxic or nutrient concern. The lack of knowledge of the phase associations of toxic metals in sediments is the largest deficiency in our understanding of the environmental hazard posed by metal contamination. This study examined the sedimentary partitioning...
The mixed metal compound, Chromated Copper Arsenate, or CCA, has been widely used as a wood preservative. The metal ions in CCA, CrO²⁻₄, Cu²⁺, and AsO³⁻₄, have been found in contaminated surface and subsurface soils and groundwater nearby some wood preservative facilities and nearby wood structures. Iron oxides are a...
Chromium spills on soils are causing severe groundwater contamination
problems. To increase the performance of cleanup methods, the chemical behavior
of chromium in soils and its transport through soils have to be understood. The
objectives of this research were to investigate the sorption characteristics of
chromium(VI) in soil and to...
Chromium, an element of widespread use, is toxic in some
forms. Improper disposal of waste chromium products has
resulted in contamination of many sites throughout the United
States, including the United Chrome Products Superfund site
in Corvallis, Oregon. A better understanding of chromium
chemistry is needed to facilitate the remediation...
Feedlot finishing of beef cattle in Southern Alberta involves
income risk due to the variability of prices of feeders, feed and
finished cattle. Several strategies are available to reduce this
risk, including hedging of cattle on feed, participation in a Federal-
Provincial government and producer established income stabilization
program for...
Several potential sorbent materials containing iron oxides were prepared and evaluated for potential to remove divalent metals from waste waters. These included a ferrihydrite-coated sand, maghemite incorporated in Dowex[Trademark] ion exchange resin, gothite and two thermally activated ferrihydrites.

Commercial production of soybeans in Oregon has been limited. In
1977, less than 1,500 acres were grown, primarily in the Columbia Basin
area. However, interest in soybeans as a possible "new crop" for Oregon
has arisen because of the (1) recent strong soybean price, (2) the high
cost of transporting...
The traditional practice on beef cow-calf ranches in the high
desert region of Eastern Oregon has been to breed the cows to calve
in the Spring months. Interest has been growing recently in the practice
of Fall-calving; that is, breeding cows to calve in the months of
October and November....
