Studies on the human umbilical cord

Creator:: Winters, Ronald Howard
Abstract:: 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...

The relationship between environmental lighting and hydroxyindole-o-methyltransferase activity in the pineal gland of steelhead trout (Salmo gairdneri)

Creator:: Smith, John Robert
Abstract:: 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....

Evaluation of cold in-place recycling of asphalt conrete pavements in Oregon

Creator:: Scholz, Todd
Abstract:: 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...

Cardiac output and respiratory measurements in the rainbow trout and their application to the study of blood and water flow limitations on chemical flux at the gill

Creator:: Schmieder, Patricia K. (Patricia Kathleen)
Abstract:: 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...

Sediment characteristics and the trophic status of four Oregon lakes

Creator:: Meyerhoff, Roger Dean
Abstract:: 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...

Landscape occupancy by free ranging cattle in northeast Oregon

Creator:: Wilson, Kerry D.
Abstract:: 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...

Pineal and retinal acetylserotonin methyl-transferase activity in trout

Creator:: Smith, John Robert
Abstract:: Pineal acetylserotonin methyltransferase (ASMT) activities in rainbow trout were reported on by Hafeez and Quay (1971). The validity of certain assay parameters used by these researchers were investigated. With the exception of incubation temperature, all parameters studied proved to be quite valid. Temperature studies indicated a low stability for trout...

A study of some physiological properties of ovine and bovine utero-ovarian arteries

Creator:: Kuhl, Lynda Marie
Abstract:: The utero-ovarian vasculature of domestic animals has been a popular research subject, especially concerning the roles of the uteroovarian artery and vein in the unilateral luteolytic phenomenon demonstrated in these animals. No reports in the literature, however, have been found regarding the smooth muscle physiology of these vessels. The present...
