Expectations for technology proficiency in counseling and counselor education have increased; nevertheless, very little information is available in the counseling literature which describes how to effectively evaluate online resources from a design and utility standpoint. This study provides a model for such assessments, employing an affordable small scale usability study...
Using off-the-shelf search technology provides a single point of access into library resources,
but we found that such commercial systems are not entirely satisfactory for the academic library
setting. In response to this, Oregon State University (OSU) Libraries designed and deployed
LibraryFind, a metasearch system. We conducted a usability experiment...
Pressurized liquid extraction (PLE) was evaluated as a method for extracting semivolatile organic compounds (SOCs) from air sampling media; including quartz fiber filter (QFF), polyurethane foam (PUF), and a polystyrene divinyl benzene copolymer (XAD-2). Hansen solubility parameter plots were used to aid in the PLE solvent selection in order to...
Many industrially important reactions use immobilized enzymes in non-aqueous, organic
systems, particularly for the production of chiral compounds such as pharmaceutical precursors.
The addition of a spacer molecule (“tether”) between a supporting surface and enzyme often
substantially improves the activity and stability of enzymes in aqueous solution. Most “long”
linkers...
Ceratomyxa shasta is a myxozoan parasite identified as a contributor to salmon mortality in the Klamath River, USA. The parasite has a complex life cycle involving a freshwater polychaete, Manayunkia speciosa and a salmonid. As part of ongoing research on how environmental parameters influence parasite establishment and replication, we designed...
Analytical methods capable of trace measurement of semi-volatile organic
compounds (SOCs) are necessary to assess the exposure of tadpoles to contaminants as a
result of long-range and regional atmospheric transport and deposition. The following
study compares the results of two analytical methods, one using pressurized liquid
extraction (PLE) and the...
The immune toxicity of the ubiquitous environmental contaminant 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD), commonly referred to as dioxin, has been studied for over 35 years but only recently has the profound immune suppression induced by TCDD exposure been linked to induction of regulatory T cells (Tregs). The effects of TCDD are mediated through...
Bacteriophage S-CRM01 has been isolated from a freshwater strain of Synechococcus and shown to
be present in the upper Klamath River valley in northern California and Oregon. The genome of this
lytic T4-like phage has a 178,563 bp circular genetic map with 297 predicted protein-coding genes
and 33 tRNA genes...
OBJECTIVE – To determine the effect of 3 differing transfusion techniques on survival of autologous canine red blood cells (RBCs).
DESIGN – Prospective, blinded study.
SETTING – University Teaching Hospital.
ANIMALS – Nine healthy dogs.
INTERVENTIONS – Three distinct preparations of RBCs, each representing ~1% of red cell mass, were...
Ecohydrological connectivity is a system level property that results from the linkages in the networks of water transport through ecosystems, by which feedbacks and other emergent system behaviours may be generated. We created a system dynamics model that represents primary ecohydrological networks to examine how connectivity between ecosystem components impacts...
