This paper details the development and pre-testing of a questionnaire designed for assessing the user experience of a View-Master virtual reality headset, and discusses the theory in the field of user experience used to carry out that effort. A group of eight researchers drafted the questionnaire collectively, with the intent...

Cover crop establishment in late-season crops, like sweet corn, may be difficult due to the relatively short operational window following crop harvest. In regions like western Oregon, where fall-precipitation can occur when the crop is still in the field, cover crops may not be able to be planted, due to...
Faithful segregation of genetic material during cell division is essential to all life on earth. In eukaryotes, the mitotic spindle – a bipolar array consisting of cytoskeletal filaments called microtubules – is the cellular machinery responsible for this function. The mitotic spindle requires both exquisite spatiotemporal organization and the generation...
A trait based approach was used to assess impacts of overstory density and thinning on understory vegetation components related to wildlife habitat. The relationship between overstory basal area and understory vegetation for species grouped by traits, such as production of flowers, fleshy-fruit and palatable leaves, was characterized in thinned and...
The North Pacific humpback whale (Megaptera novaeangliae) population has been increasing at an average annual rate of ~6% since the early 1990s. In northern Southeast Alaska alone, there are now more whales than estimated for the entire North Pacific several decades ago. An understanding of how this growing population is...
In September of 1989, the site of an active seafloor methane vent was confirmed
approximately 20 km off the coast of Oregon in shelf waters 135 m deep. The location of
the vent had been described to Oregon State University oceanographers by a local
commercial fisherman. Preliminary observations in 1989...
This research focused on anaerobic transformation of trichloroethene (TCE), a
groundwater contaminant. The mixed anaerobic Evanite culture (EV) was studied to determine community behavior and composition responses to different electron donors and chloroethene electron acceptors. The potential toxicity from high concentrations of TCE and its daughter product cis-1,2-dichloroethene (cDCE) was...
At frequencies exceeding 1-2 GHz, the reactive nature of a silicon substrate must be accounted in the substrate network models used in substrate coupling simulation. High-frequency substrate models, containing reactive components, must be validated through high-frequency network analyzer measurements. Prior fabricated test fixtures have been modified to enable high-frequency (up...
