Himalayan blackberry, also known as Armenian blackberry, is a widespread invasive species in western Oregon and also grows in some eastern Oregon riparian zones. Commonly found in riparian areas, it also grows along roadsides and fence corridors and in open woodlands, logged areas, and other disturbed sites. It grows best...

Himalayan blackberry (Rubus armeniacus, formerly Rubus discolor and Rubus procerus) is a European shrub that was introduced in the United States as a crop in the late 19th century. It escaped cultivation and has since invaded a variety of sites, including low-elevation streamside areas throughout the Pacific Northwest. Listed as...

Some important factors that affect the dimensional
control of oxide films on silicon were studied. Both N- and
P-type silicon with resistivities in the range of
0.014 to 200 ohm-cm and a (111) surface orientation
were employed in this experiment. The etching rates of
silicon dioxide in hydrofluoric acid (111)...
The purpose of this work was to develop a dynamic partial order model of II electrolyte solutions which avoids inconsistencies present in the Debye-1-Iuckel and 1n related theories. It is shown that our results are consistent with activity coefficient data in aqueous electrolyte solutions. The main features of our work...
Fiber flax (Linum usitatissimum L.) production in the Willamette Valley ended in
Oregon around 1957 before newly developed technology and fiber cultivars were
available. The purpose of this research was to explore the use of modern methods and
new cultivars.
Field studies were conducted to evaluate cultivars and optimum cultural...
Heparin was modified with adipic diliydrazide and covalently linked to surface-activated silica. Contact angle measurements were made to determine changes in surface at various stages of the derivatization. Xray photoelectron spectroscopy was used to analyze the elemental composition of the surface at each step of immobilizing heparin as well and...
Planting trees in riparian areas is increasingly common in Oregon as part
of efforts to improve fish habitat, water quality, and other riparian functions. Yet tree survival and growth are poor in many projects, and some fail outright.
