Background—The effect of intensive blood pressure (BP) lowering on kidney function among individuals with established cerebrovascular disease and preserved estimated glomerular filtration rate (eGFR) is not established.
Methods and Results—Among 2610 participants randomized to a lower (<130 mm Hg) versus higher (130–149 mm Hg) systolic BP target with repeated measures...
OBJECTIVE: To evaluate the effectiveness of a 3-month treadmill desk intervention in eliciting changes in physical activity and sedentary behavior among overweight/obese office workers. METHODS: A randomized controlled trial was conducted among overweight/obese office workers (n=41; mean age = 40.1 ± 10.1 years) at a private workplace. Participants were randomly...
Acid deposition and repeated biomass harvest have decreased
soil calcium (Ca) availability in many temperate forests worldwide, yet
existing methods for assessing available soil Ca do not fully characterize
soil Ca forms. To account for discrepancies in ecosystem Ca budgets, it
has been hypothesized that the highly insoluble biomineral Ca...
BACKGROUND: In the prenatal period, women can have sustained contact with nurses and other clinicians, forming relationships that are likely to be health enhancing both for the woman and her unborn child. Yet first trimester care use in Oregon dropped noticeably over the past decade. In comparison with Washington State,...
International immersion experiences do not, in themselves, provide students with the opportunity to develop cultural competence. However, using an anthropological lens to educate students allows them to learn how to negotiate cultural differences by removing their own cultural filters and seeing events through the eyes of those who are culturally...
OBJECTIVE: Pharmacokinetic interactions exist between combined
oral contraceptives and protease inhibitors (PI). However, such
information is lacking for progestin-only oral contraception. We
sought to define the steady-state pharmacokinetic interaction between
norethindrone (NET) and PI in HIV-infected women.
METHODS AND DESIGN: We conducted an open-label, prospective,
nonrandomized trial to characterize the...
Fuel accumulation and climate shifts are predicted to increase the frequency of high-severity fires in pon-derosa pine (Pinus ponderosa) forests of central Oregon. The combustion of fuels containing large downedwood can result in intense soil heating, alteration of soil properties, and mortality of microbes. Previousstudies show ectomycorrhizal fungi (EMF) improve...
Dibenzo(def,p)chrysene (DBC), (also known as dibenzo[a,l]pyrene), is a high molecular weight polycyclic aromatic hydrocarbon (PAH) found in the environment, including food, produced by the incomplete combustion of hydrocarbons. DBC, classified by IARC as a 2A probable human carcinogen, has a relative potency factor (RPF) in animal cancer models 30-fold higher...

This study was conducted by the School of Forestry at Oregon State University to provide some of the information needed by the Oregon Board of Forestry to develop a forestry program for Oregon. The study makes three contributions: One, a data base that provides an up-to-date timber inventory and information...
During 1997–1998, we investigated the influence of both the relative abundance of truffles, preferred food
items, and microhabitat structure on the occurrence of northern flying squirrels (Glaucomys sabrinus Shaw) in oldgrowth
forest habitat of the Sierra Nevada Range, U.S.A. Following live-trapping sessions, we searched the forest floor
for truffle diggings...

We study a class of two-generator two-relator groups, denoted J[subscript n](m, k), that arise in the study of relative asphericity as groups satisfying a transitional curvature condition. Particular instances of these groups occur in the literature as finite groups of intriguing orders. Here we find infinite families of non-elementary virtually...

Date of coverage: 1965-1972. Sample numbers, weights of ashed tested samples, dates samples went into detector. End of book has Atomic absorption record for Zn.
During July 1970, albacore boats trolling surface jigs (jig boats) had record catches in an area off the mouth of the Columbia River. The jig fishery declined suddenly in late July and was poor throughout the remainder of the summer. No obvious oceanographic changes were correlated with these drastic changes...

The effects of precommercial thinning on the understory vegetative cover of 16- to 18-year-old spruce–hemlock (Picea sitchensis (Bong.) Carrière – Tsuga heterophylla (Raf.) Sarg.) stands were studied in seven replicate areas over seven growing seasons postthinning. Vegetative cover was analyzed at the class level, but species-specific effects were examined in...
A group defined by a finite presentation with cyclic symmetry admits a shift automorphism that is periodic and word-length preserving. It is shown that if the presentation is combinatorially aspherical and orientable, in the sense that no relator is a cyclic permutation of the inverse of any of its shifts,...
In 1868, the Oregon legislature designated Corvallis College as the state's land-grant agricultural school that would eventually become Oregon State University. The university was established as part of the 1862 Morrill Act, which granted states 30,000 acres to promote education in “agriculture and the mechanic arts.” William G. Robbins reveals...
Basaltic volcanism provides a window into the Earth’s mantle. Seeing through this window requires seeing through the processes of magma genesis and evolution that distort the view. Radiogenic isotope ratios, and to a lesser extent incompatible elements and stable isotope ratios, allow us to see through these distortions and infer...
