Cerium oxide nanoparticles were continuously
precipitated from a solution of cerium(III) nitrate and ammonium
hydroxide using a static microchannel T-mixer. Tmixer
synthesis results were compared with synthesis results
from batch precipitation. Findings show that the method of
mixing is important in the ceria precipitation process. Uniform
porous film structures and...
North American freshwater mussels have been subjected to multiple stressors in recent decades that have contributed to declines in the status and distribution of many species. However, considerable uncertainty exists regarding the relative influence of these factors on observed population declines. 2. We used an occupancy modelling approach to quantify...
This publication describes the parasites most commonly found in sheep and goats and outlines methods for idenitfying, testing for, and treating parasite infestations.
A toolkit for farmers, Extension agents, community organizers, and other agricultural professionals interested in starting and maintaining a successful farmer network.

In 1746, Dr John Buchanan, a recently retired medical officer in the British Army, produced a manuscript, 'Regimental Practice, or a Short History of Diseases common to His Majesties own Royal Regiment of Horse Guards when abroad (Commonly called the Blews).' Revised almost until the time of Buchanan's death in...

Haiti's political and economy history has led to a maternity care system that lies out of reach, geographically and financially, of most Haitians, resulting in excessively high maternal and infant mortality. The most common birth practitioners are homebirth midwives (matwòns), who attend roughly three-fourths of all births in Haiti (UNICEF),...
The current study examines the effects of Head Start on the development of school readiness outcomes for children living in non-parental care. Data were obtained from the Head Start Impact Study, a randomized controlled trial of Head Start conducted with a nationally representative sample of Head Start programs and families....
The influence of fertilization on disease severity is unknown in most forest pathosystems. Fertilization treatments were randomly applied to 0.01 ha plots centered on individual dominant or co-dominant Douglas-fir trees in ten Douglas-fir stands from coastal Oregon to the foothills of the Oregon Cascade Range, USA. This region is affected...
An important challenge in machine learning is to find ways of learning quickly from very small amounts of training data. The only way to learn from small data samples is to constrain the learning process by exploiting background knowledge. In this report, we present a theoretical analysis on the use...
Despite concern expressed two decades ago, there has been little recent discussion about continuing declines of migrant bird populations. Monitoring efforts have been focused almost exclusively on the breeding grounds. We describe the long-term decline of a winter-resident bird population in Guánica Commonwealth Forest, Puerto Rico, one of the last...
A central goal of green chemistry is to avoid hazard in the design of new chemicals. This objective is best achieved when information about a chemical's potential hazardous effects is obtained as early in the design process as feasible. Endocrine disruption is a type of hazard that to date has...

An overview of the 2012 Oregon Tribal Archives Institute published in the Society of American Archivist's newsletter "Archival Outlook" as part of the Jan/Feb 2013 issue, pages 8-9 and 26.
Presents pesticide and herbicide application rates and recommendations, by tree growth stage, for pests that infect fruit trees. Covers apples, pears, and cherries. Provides (1) spray program for nutrients; (2) dilutions table for wettable powder and liquid products; (3) natural enemy impact guide for tree fruit pesticides; (4) illustrated bud...
This publication is prepared to assist processors of specialty food, distributors, vendors, and food regulators of backgrounds and experience in finding specific information on producing safe specialty food products. This publication discusses the unique characteristics of specialty foods, identifies food safety concerns in specialty foods production, and provides examples of...
Incorporating a life course perspective, this qualitative study used focus groups to explore the experiences of midlife adults who were simultaneously providing support to emerging adult children and aging parents. Results indicated that adults situated in middle generations held beliefs that endorsed family-based responsibility to both younger and older members....
In the final phase of their spawning migration, Pacific salmon use chemical cues to identify their home river, but how they navigate from the open ocean to the correct coastal area has remained enigmatic [1]. To test the hypothesis that salmon imprint on the magnetic field that exists where they...
With continued development of the electronic industry, the demand for highly efficient heat removal solutions requires innovative cooling technologies. A computational fluid dynamic (CFD) study, including heat transfer, is performed for an axisymmetric, confined jet impingement experiencing boiling and coupled with vapor extraction. Boiling occurs at the target surface while...
One of the least studied areas of Information Foraging Theory
is diet: the information foragers choose to seek. For
example, do foragers choose solely based on cost, or do
they stubbornly pursue certain diets regardless of cost? Do
their debugging strategies vary with their diets? To investigate
"what" and "how"...
The cultivated strawberry is one of the youngest domesticated plants, developed in France in the 1700s from chance hybridization between two western hemisphere octoploid species. However, little is known about the evolution of the species that gave rise to this important fruit crop. Phylogenetic analysis of chloroplast genome sequences of...
Obedience and showmanship contests provide an opportunity for youth to demonstrate how well they have trained their dog and how the youth and dog work as a team.
Students in Kristin Griffin's Fall 2012 WR222 Argumentation class worked in groups to create podcasts in which they considered some aspect of Oregon State's culture, community and/or geography as it was in the past and how it is today. Their research was based in the Special Collections & Archives and...

The vitamin D receptor (VDR) mediates the pleiotropic biologic effects of 1alpha,25
dihydroxy-vitamin D3. Recent in vitro studies suggested that curcumin and poly-unsaturated fatty
acids (PUFAs) also bind to VDR with low affinity. As potential ligands for the VDR, we hypothesized
that curcumin and PUFAs would induce expression of known...
