An understanding of the factors that influence surface erosion from roads is necessary to prevent and mitigate sediment production from forest roads. This study investigated the impacts of log truck traffic and road hydrology on sediment yield from ten forest road segments in the foothills of the Cascade Mountains of...
Intravenous regional limb perfusion (IVRLP) with tiludronate is a commonly used treatment for distal limb orthopedic disease in horses, but doses and protocols are anecdotal. IVRLP exposes articular cartilage within the perfused area to tiludronate, raising concerns about safety of this treatment, as high tiludronate concentrations (≥19mg/L) were harmful for...
Field and laboratory tests were carried out to investigate the
survival of the root-nodule bacterium, Rhizobium trifolii, when
inoculated onto seeds of the pasture legume subterranean clover,
(Trifolium subterraneum L.), in order to improve the nodulation
and establishment of this plant in acid soils.
Field experiments were carried out in...
State departments of transportation, transportation consultants, and other transportation agencies are always in need of data that can be used to better understand how different modes of transportation use the road and highway systems. A variety of automatic data collection technologies have been used to gather these data including video...
A mechanism is a constrained kinematic chain composed of
gears, links, cams, or the like. Mechanisms are the building blocks
of all machines, and, as such, their evaluation is of considerable
importance to the mechanical designer. Because the mathematical
analyses of systems with four or more moving members has been...
The herbicides Diquat (1, 1'-ethylene-2, 2'-dipyridylium
dibromide), Paraquat (1, 1'-dimethyl-4, 4'-dipyridylium dichloride),
and Gramoxone (1, 1'-dimethyl-4, 4'-dipyridylium dimethyl sulphate), and the spreader X-77, a mixture of alkylaryl-polyethylene
glycol, free fatty acids and isopropanol, were tested by
several soil microbial methods in an attempt to find out if concentrations of these...
This investigation was undertaken to characterize and evaluate
the forage production and utilization of the successional vegetation
of the mixed conifer forest.
Field studies were carried out during the summers of 1962
through 1964 at the Eastern Oregon Experiment Station Hall Ranch
which is located 12 miles southeast of Union,...
The purpose of this study was to determine the actual retirement
income for a selected group of retired persons from Oregon
State University in order to obtain a more comprehensive understanding
of the factors affecting retirement benefits. Statistical
data on the records of 122 retired employes who were members and...
In a search for new therapeutic agents, a series of Mannich bases
derived from the following 2-phenylindolizines were prepared: 2-phenylindolizine, 1, 2-diphenylindolizine, 3-methyl-2-phenylindolizine,
3-ethyl-2-phenylindolizine, and 1-(2-hydroxyethyl)-2-phenylindolizine.
The investigation was based on the speculation that indolizine
analogs of physiologically active indoles might be useful medicinally.
A certain group of indoles, all...
The objective of this study was to compare the total collection
(in vivo), nylon bag, and in vitro digestibility techniques under
standardized conditions. Twin steers were used simultaneously to
measure the digestibility of five rations consisting of the following
ratios of alfalfa hay to steamed roller barley: 4:0 (I), 3:1...
