The authors varied the number of red alder retained with 300 Douglas-fir per acre on a high-quality site in coastal Oregon. Alder densities of 0, 20, 40, and 80 per acre were tested. The authors' fifth treatment eliminated nitrogen-fixing alder, but substantial nitrogen fertilizer. Treatment 6 had neither thinning nor...
Horticultural and nursery crops are the leading agricultural commodity in Oregon. Among currently grown nursery plants, Verbena x hybrida is a staple ornamental. It is grown and shipped worldwide, thus requiring a high level of certainty concerning the plants’ health and potential viability. V. x hybrida cultivars have been infected...

Aristotle, as a precursor to the scientists and magical practitioners of the twelfth century or the barber-surgeons of the sixteenth century, understood monsters to be human or animal beings deformed by...
My thesis is comprised of two articles, titled "Interpreting Britomart's Encounters with Art: The Cyclic Nature of Ekphrasis in Spenser's Faerie Queene III," and "Picture This, Imagine That: Teaching Visual Literacy in the Disciplines." The purpose of my first article is to argue that Edmund Spenser uses ekphrasis in his...
In this study a method has been demonstrated by which
the departure from nucleate boiling ratio (DNBR) can be
readily determined for nuclear transients through application
of the COBRA-IIIC/MIT computer code. For input,
boundary conditions were specified relating the time-dependent
variations of core inlet coolant temperature,
system pressure, core heat...
Acoustic scattering layers of biological origin have been observed for nearly 70 years across the world’s oceans. The organisms that comprise these layers are known to be important features in most oceanic ecosystems, providing a vital trophic link between small phytoplankton grazers and larger species. There are many aspects of...
