Urban stormwater runoff with a high impervious area can significantly impact pollution concentrations of receiving water bodies. The use of low impact development (LID), which mimics the hydrological properties of the site before development, has been studied in an increasing number of studies, and the available database has shown to...
Gonadectomy has been associated with a 1.5-2 fold increase in the occurrence of canine hip dysplasia and a 2-3 fold increase in the occurrence of canine anterior cruciate ligament (ACL) injury. In intact dogs, luteinizing hormone (LH) is secreted from the adenohypophysis to stimulate the synthesis of gonadal hormones, which...
This thesis focuses on shared use lane facilities and road user understanding. Shared use lanes (sharrows) are a common solution for road facilities that are too narrow to accommodate a full bicycle lane and where the local jurisdiction wants to reduce dooring crashes. In recent years, engineers have focused on...
The myriad of problems facing the world today are increasingly complex, dynamic, and transcend multiple domains necessitating the need for an equally complex and trans-disciplinary approach to solve these problems. Systems thinking promises to provide the skills necessary for all citizens of the world, not just the experts, to handle...
This research examines two of parameters of vectorial capacity for mosquitoes associated with catch basins in Corvallis, Oregon. The parameters of interest were determining 1) abundance of the mosquito species associated with the catch basins and 2) feeding patterns of local mosquito species. Three species of mosquitoes were collected from...
Xanthohumol, a prenylated flavonoid found in hops and beer, possesses a long-standing reputation to improve health. Xanthohumol’s cytotoxicity to a wide variety of cancer cell lines is well-established. Herein we provide further insight into the cytotoxicity of not only xanthohumol, but also its non-estrogenic derivatives, to a number of colonic...
Structural engineered wood manufacturers need a quantitative measurement technique to determine the ratio of wood to adhesive failure in their shear specimens. Visual estimation of percent wood failure has long stood as an extremely subjective quality control approach according to ASTM D5266 – Standard Practice for Estimating the Percentage of...
Over the last several decades, there has been a marked increase in the amount of science outreach to the public with little attention paid to how scientists who conduct outreach perceive learning and how that applies to their outreach activities. This increase in outreach efforts is linked to the National...
The European hazelnut (Corylus avellana L.) is a tree nut crop that is important in Oregon, which produces 99% of the United States’ hazelnuts but only 5% of the world’s supply. In order to maintain this market share, farmers in Oregon need cultivars that produce high quality nuts, mature early,...
Steep slope timber harvesting often falls under scrutiny of labor, safety, and operational challenges, but is beginning to advance past these barriers through substantial technological progression. Across previous decades, large advancements of technology have occurred in ground-based timber harvesting systems, giving mechanized options to every phase of timber harvesting. These...
Sunscreen products are used worldwide to protect the skin from ultraviolet radiation. However, some of the ingredients used in sunscreen products are fatal to coral reefs especially in areas where tourism is a large part of the economy. In this study, we explored a synthetic route to produce 4-deoxygadusol, which...
Three kkeeyy variables are examined to determine their influence on
the process of community planning at Corvallis, Oregon. These are
(1) the setting of priorities, (2) organization and (3) external
reference. Interactions of goals program participants were recorded
as the community responded to comply with Oregon Senate Bill #100's
requirement...
Globally, access to safe, reliable drinking water sources is a major challenge of this generation. Protected sources of drinking water provide communities with a sustainable, vital resource, yet many public water suppliers lack legal authority over their source water protection (SWP) area, especially in surface water systems. Absence of legal...
This study was conducted to observe the manner in which three local
public interest organizations participated in a local, environmentallyoriented
decision process. The study period began in December, 1978,
with the passage of a revised solid waste ordinance (Ord. 78-102) for
the City of Corvallis, OR. The main forum for...
This thesis is an IRB-exempt oral history focused on the non-profit Corvallis Multicultural Literacy Center (CMLC) in Corvallis, Oregon. The CMLC, formerly on 9th Street, was known to many community members as the Yellow House. The Yellow House was a dedicated community-based space where people of all cultures could come...
The WNBA is a league that has been characterized by struggle ever since its inception in 1996. The biggest reason for nearly all of its problems lies with one source: money. The WNBA simply does not have enough money to make it a functionable professional sports league. As a result...
