Studies were initially conducted to determine the action of
intravenous serotonin on perfused segments of human umbilical
cords in vitro. Intravenous serotonin, via bolus injection or
continuous infusion, was found to elevate venous perfusion pressure,
while intra-arterial serotonin failed to alter venous pressure.
Norepinephrine, administered to the venous perfusate, was...
Pineal hydroxyindole-0-methyltransferase (HIOMT) activity
was monitored over a 24 h period under three different photoperiods,
16L:8D, 8L: 16D, and 12 L:12D. It was observed that in all three
groups of fish HIOMT activity was high' during the dark portion of the
photoperiod in comparison to activity during the light portion....
Wheat is an important part of a healthy and balanced diet, requiring six servings per day to maintain a recommended 2000 Calorie intake (McRae, 2017). Because of this more land than almost any other kind of cereal is set aside for the purposes of growing wheat. To keep up with...
While it can be said that peer mentor-mentee relationships in college can lead to meaningful connections and interpersonal support, there is a lack of literature about how exactly mentor-relationship connections are made. This study examines the relationship building strategies that peer mentors used to connect with their mentees in the...
Significant use of cold in-place recycling (CIR) has occurred in
Oregon since 1984 as an alternative to other rehabilitation techniques
or to the reconstruction of distressed asphalt concrete (AC) pavements.
Due to the initial success of the projects cold recycled during 1984-85,
the Oregon Department of Transportation (ODOT) and Oregon...
A method has been developed for the continuous automated monitoring
of cardiac output in adult rainbow trout. Average cardiac output measured under
control conditions and varied environmental conditions of hypoxia and post-hypoxia
was significantly higher (P≤ 0.05) in male than female trout. The cardiac
output of trout in spawning condition...
There is evidence that recent ecological changes in lakes and their watersheds can be detected from analysis of lake sediments. This study was initiated to correlate
changes in some sediment characteristics of four Oregon lakes with past cultural developments of the lakes and their watersheds. The lakes chosen for this...
Global Positioning System (GPS) and Geographic Information System (GIS) technologies were employed to evaluate cattle occupancy of three landscape attributes on three different grazing allotments administered by the Wallowa Whitman National Forest in Northeast Oregon. Topographic characteristics of slope; 0-4%, 4-12%, 12-35% and >35% were evaluated as well as north...
