This study shows how patronage framed and fashioned the careers of Thomas Hobbes and
his patron William Cavendish, the earl of Newcastle. Newcastle's protection allowed
Hobbes to articulate heterodox ideas without immediate fear of reprisal. It also enabled
him to solidify his status as a gentleman and the intellectual equal...
A simple theory is presented for steady geostrophic circulation of a stratified fluid in a rectangular basin with a circumpolar connection. The interior flow obeys the β-plane Sverdrup vorticity balance, and the circulation is closed by geostrophic boundary currents. The circulation is forced by surface thermal gradients and wind-driven Ekman...
Discusses what land use practices can impact riparian areas and the techniques landowners, volunteers, and professional resource managers can use to improve and protect riparian function.
Examines the eating habits of cows, sheep, horses, and goats, and explores how forage selection, pugging, trampling, and fencing contribute to a pasture's health and sustainability.
Phenoxy herbicides include 2,4-D, MCPA, Crossbow, Banvel,
Garlon, Weed-B-Gone, and Brush Killer. They also are the active
ingredient (2,4-dichlorophenoxyacetic acid, 2-methyl 4-chlorophenoxyacetic acid, triclopyr, or dicamba) in “weed and feed” and brush control products for use in the home landscape.
Models of magnetic and gravity anomalies along two E-W transects offshore central Oregon, one of which is coincident with a detailed velocity model, provide quantitative limits on the structure of the subducting oceanic crust and the crystalline backstop. The models indicate that the backstop-forming western edge of the Siletz terrane,...
A mesoscale atmospheric model is used to address the characteristics of stratified flow bounded by a side
wall along a varying coastline. Initial Froude number values are varied through alteration of marine inversion
strength, permitting examination of supercritical, subcritical, and transcritical flow regimes encountering several
coastal configurations. Consistent with shallow...
The diffusivity dependence of internal boundary layers in solutions of the continuously stratified, diffusive
thermocline equations is revisited. If a solution exists that approaches a two-layer solution of the ideal thermocline
equations in the limit of small vertical diffusivity kᵥ, it must contain an internal boundary layer that collapses
to...

This book is offered to youth leaders and teachers as a tool to help young learners discover some of the wonders that the sea has to offer. It is also a tool for youth development. The goal of youth programming is to provide developmentally appropriate opportunities for young people to...
The European Centre for Medium-Range Weather Forecasts (ECMWF) and Institut Francais Pour la Recherche et l’Exploitation de la Mer European Remote-Sensing Satellite, named IFR2, surface wind velocity data products are compared during July 1995 over the Arabian Sea. Substantial differences were found. The central positions of the maximum isotach were...
Curly dock (Rumex crispus L.) is a perennial. It does
not have creeping roots or rhizomes (Figure 1). Leaves
are oblong to nearly lanceshaped, often 12 inches or more
long, with wavy (crisped) margins (Figure 2). Erect, generally
unbranched stems up to 5 feet tall are produced in spring
and...
The objective of this series is to help improve the competitiveness of
Oregon’s wood products manufacturers. This can be achieved by fostering a companywide focus on and dedication to continuous quality improvement.
W. Edwards Deming (1982) described the “chain reaction of quality.”
1. Quality is improved.
2. Costs decrease due...
The goal for Part 2 is to build management understanding and
confidence in SPC as a profit-making tool. It is unreasonable to expect
managers to commit to and support SPC training and implementation
if they do not understand what SPC is and how and why it works. This
publication discusses...
Most expressions for infiltration rely upon the assumption of vertical uniformity in soil texture and hydraulic properties. We present an extension of the results of Beven [1982, 1984] for infiltration and lateral flow in soils with decreasing permeability with depth. Unlike Beven, we base the derivations upon joint changes in...
High-quality forages, such as alfalfa and grasses, are important for efficient milk production from dairy cows. Forages provide the effective fiber that is critical for good health and longevity. Inadequate
effective fiber in the cow’s diet is one reason for acidosis and milk fat
depression. Historically, when forage quality changed,...
A high-resolution upper-ocean survey of a cyclonic jet meander and an adjacent cyclonic eddy in the California Current region near 38°N, 126°W was conducted as part of the summer of 1993 Eastern Boundary Currents program. Temperature and salinity were measured from a SeaSoar vehicle, and velocity was measured by shipboard...
Measurements of a fresh surface anomaly (fresh lens) produced by rainfall during a westerly wind burst have been analyzed. The measurements were made in December 1992 as part of the Coupled Ocean–Atmosphere Response Experiment in the western equatorial Pacific (2°S, 156°E). Measurements included radar estimates of rainfall, upper-ocean temperature (T),...

Annual ryegrass (Lolium multiflorum Lam. or Lolium perenne L. ssp. multiflorum (Lam.) Husnot, also called Italian rye grass) is a cool season annual bunchgrass native to southern Europe. It is closely related to perennial ryegrass (Lolium perenne L.). Both are widely distributed throughout the world, including North and South America,...
Orchardgrass (Dactylis glomerata L.) is native to western and central Europe, but has been grown in North America for more than 200 years. In the 1830s, settlers in western
Virginia recognized the forage value of shade tolerant
D. glomerata plants growing in an orchard.
Tall fescue (Festuca arundinacea Schreb.) is a perennial, cool-season bunchgrass that is grown for pasture, hay, and silage. Native to Europe and North Africa, it was introduced from Europe to North and South America.
Perennial ryegrass (Lolium perenne L.), also called English ryegrass, is a cool-season perennial bunchgrass native to Europe, temperate Asia, and North Africa. It is widely distributed throughout the world, including North and South America, Europe, New Zealand, and Australia.
A mechanism by which long planetary waves in the ocean may propagate significantly faster than the classical long baroclinic Rossby waves is investigated. The mechanism depends on the poleward thickening of intermediate density layers and the concomitant thinning of near-surface and deep layers. These features of the mass distribution are...
The hydrography in the central and east basins of the Bransfield Strait is examined using data collected along a track 340 km long through the strait in November 1995, in conjunction with historical data from the NODC database. Circumpolar Deep Water (CDW) was seen throughout most of the central basin...
Clark is a hazelnut selection developed by Oregon State University.
Trees of this genotype are about 30 percent smaller than ‘Barcelona’ yet
have comparable yields to ‘Barcelona.’ This selection has good quantitative resistance to eastern filbert blight (EFB).
Harvest is 7–10 days earlier than‘Barcelona’ and nuts are free-husking.
Nuts have...
This article describes the results of numerical experiments carried out with a general circulation ocean model to investigate the effect of the seasonal cycle of the wind forcing on the Agulhas transport. Two cases are described. The first was initialized with temperature and salinity values obtained by horizontally averaging Levitus...
The vertical structure of coastal-trapped disturbances in several idealized models of a stably stratified lower atmosphere is examined. The vertical structure and phase speeds of the trapped modes depend on the resting stratification and the height of the orographic step. The presence of a stable layer above the boundary layer...
The distributed-microstructure model for the flow of single phase
fluid in a partially fissured composite medium due to Douglas-Peszyńska-Showalter [12] is extended to a quasi-linear version. This model contains the
geometry of the local cells distributed throughout the medium, the flux exchange
across their intricate interface with the imbedded fissure...
The extent to which parent trees within breeding zones of coastal Douglas-fir (Pseudotsuga menziesii var. menziesii (Mirb.) Franco) are locally adapted to their native environments was evaluated. Forty families from each of one Coastal and one Cascade breeding population in Oregon were assessed for cold hardiness and growth phenology, and...
The response of the upper ocean to westerly wind forcing in the western equatorial Pacific was modeled by means of large-eddy simulation for the purpose of comparison with concurrent microstructure observations. The model was initialized using currents and hydrography measured during the Coupled Ocean–Atmosphere Response Experiment (COARE) and forced using...
In the Sierra Nevada, distributions of forest tree species are largely controlled by the soil-moisture balance. Changes in temperature or precipitation as a result of increased greenhouse gas concentrations could lead to changes in species distributions. In addition, climatic change could increase the frequency and severity of wildfires. We used...

The location of the Antarctic Polar Front (PF) was mapped over a 7-year period (1987-1993) within images of satellite-deprived sea surface temperature. The mean path of the PF is strongly steered by the topographic features of the Southern Ocean. The topography places vorticity constraints on the dynamics of the PF...
We characterized the structure and composition of unmanaged riparian forests in three river basins in Oregon’s coastal mountains. Our objective was to evaluate stand attributes at three spatial scales: streamside (site), drainage network (stream order), and basin (subregion). Data on basal area, species composition, snag density, canopy cover, and tree...
Alternatives to clear-cutting are being implemented to increase biodiversity of managed forests in the Pacific Northwest. Lichens are an integral component of old growth, but lichen biomass develops slowly in forests. We evaluated the long-term potential of live tree retention for lichen conservation in Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) forests....
Traditionally, winemakers have relied upon 'spontaneous' malolactic fermentation (MLF) from indigenous species which may take weeks or months to go to completion depending upon the wine and the cellar conditions. Control of MLF has increased with the development of pure MLF bacterial starter cultures. Pure cultures started from slants generally...

Increasing ecological awareness led to the conceptualization and implementation of sustainable production systems such as Integrated Production. Integrated Production (IP) aims at achieving optimum yields of high quality fruit utilizing environmentally safe procedures. Priority is given to the utilization and enhancement of natural regulating processes and to the reduction of...
Stuck and slow fermentations are a major concern of winemakers. If the levels of fermentable nitrogen in juice are too low, fermentations will be slower and may stop or 'stick' before all the fermentable sugar is utilized by the yeast. Sluggish and stuck fermentations are also sometimes accompanied by production...
A broad range of factors influence wine grape quality and manipulation of these factors has stimulated interest among grape growers, wine makers, and research scientists alike. One such factor affecting wine grape quality is crop level, particularly for Pinot noir. Since the capacity of a vine to ripen fruit depends...
The physical interpretation of simultaneous multiangle observations represents a relatively new approach to remote
sensing of terrestrial geophysical and biophysical parameters. Multiangle measurements enable retrieval of physical scene
characteristics, such as aerosol type, cloud morphology and height, and land cover (e.g., vegetation canopy type), providing
improved albedo accuracies as well...
Meanders of the shelf break front in the Mid-Atlantic Bight (MAB) during April and May of 1997 were associated with chlorophyll enhancement along a hydrographic and a topographic feature. The hydrographic feature was the surface outcrop of the front, which ranged from ~10 to >100 km seaward of the shelf...
Heartwood durability of Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco var. menziesii) was studied as a function of vertical and radial position in boles of trees with a wide range of leaf area/sapwood area ratios. Six 34- year-old trees were harvested from each of three plots established 14 years before: very dense,...
Seedlings of western redcedar (Thuja plicata Donn ex. D. Don), western hemlock (Tsuga heterophylla (Raf.) Sarg.), and Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) were transplanted into soils with low and high levels of available NO3 – (and total N). Current-year foliage was sampled after 10 weeks to determine the effect of...
