The new varietal trial at SOES was monitored during the growing season and during ripening by David Sugar and Porter Lombard (see Winegrape Variety Trial in Southern Oregon). The 1993 vintage was a late ripening season and not all the varieties developed sufficient maturity for experimental wine production. Tempranillo, Viognier,...
Minimal pruning continues to look like a production system worthy of consideration in small scale commercial trials. In 1993, in a trial on Chardonnay at Woodhall vineyard, minimal pruning was compared to standard cane pruned vines on a vertical trellis. This was the second year of the trial.
We have measured voltage-current characteristics for YBa₂Cu₃O₇ thin films in magnetic fields from 5
T to ambient, including some in the millitesla range. In all cases, the resistivity —current density isotherms
can be separated into two classes: those which exhibit upward curvature, and have constant
resistivity at low currents, and...
The divergence theorem as usually stated cannot be applied across a change of signature unless it is reexpressed to allow for a finite source term on the signature change surface. Consequently all conservation laws must also be ‘‘modified,’’ and therefore insistence on conservation of matter across such a surface cannot...
The divergence theorem in its usual form applies only to suitably smooth vector fields. For vector fields which are merely piecewise smooth, as is natural at a boundary between regions with different physical properties, one must patch together the divergence theorem applied separately in each region. We give an elegant...

The largest known Quaternary silicic lava body in the world is Cerro Chao in north Chile, a 14-km-long coulée with a volume of at least 26 km³. It is the largest of a group of several closely similar dacitic lavas erupted during a recent (< 100,000 year old) magmatic episode...
Sufficiently large lake loads provide a means of probing rheological stratification of the crust and upper mantle. Lake Minchin was the largest of the late Pleistocene pluvial lakes in the central Andes. Prominent shorelines, which formed during temporary still‐stands in the climatically driven lake level history, preserve records of lateral...
Satellite altimetry has previously been used to map the magnitude of the surface eddy variability of the global oceans, but the direction of the time-variable velocities have been more difficult to determine. Here, a technique is presented for resolving both magnitude and direction of residual surface geostrophic velocities at Geosat...
The decay of a downward propagating near-inertial wave was observed over four days. During this short period, the energy of the near-inertial wave decreased by 70%. The shear layers produced by the wave were regions of enhanced turbulent dissipation rates. The authors estimate that 44% of the observed change in...
A detailed investigation of the upper ocean during convection reveals
1.
• the vertical structure of potential temperature, θ, to be steady in time, and
2.
• the current shear to vanish in the bulk of the mixed layer.
These imply that a “slab”-type model may be an adequate representation...
Practical hydrostatic ocean models are often restricted to statically stable configurations by the use of a convective adjustment. A common way to do this is to assign an infinite boat conductivity to the water at a given level if the water column should become statically unstable. This is implemented in...
Length of survival of the monogenetic trematode Gyrodactylus stellatus in serum and mucus collected from English soles Pleuronectes vetulus at different stages of a laboratory epizootic suggests that both the mucus and serum may be involved in resistance to the parasite. In general, trematode survival was shorter in the serum...
Market issues are often critical to the regional and national benefits that can be generated from fisheries management. In actual policy analysis, however, market considerations are often treated as exogenous to the fisheries policy problem. Examples illustrate the relationships between product characteristics, market demand, and regulatory management. A multiple-objective socioeconomic...

in a drought, every gallon of water saved
means more crop production. There are many
places in a typical irrigation operation where
water is lost. Here are some prudent management
practices that can conserve water and
possibly make the difference between making
a profit or taking a loss.
Note: These...
The Expanded Food and Nutrition Education program (EFNEP) helps limited income families in Oregon improve their nutrition practices. These include learning to: □ Stretch family food dollars □ Choose foods for better nutrition for family members □ Purchase food for nutritional needs □ Improve food production, preparation, storage, safety, and...

Welcome to nutrition education with the Nutri-Kids! The purpose of this unit, Nutri-Kids Go Around the World, is to introduce thirdgrade children to food and food customs of other cultures, and to provide them with nutrition and health information they can use to live healthier lives.

Backpack sprayers are relatively easy to use--and to misuse. The video shows basic sprayer components and how to use them appropriately. It also outlines how to calibrate the sprayer, calculate application rates, and mix pesticides.
The Horsetail (Equisetaceae) family comprises 30 species, all in the ancient genus Equisetum. During the Carboniferous age (more than 230 million years ago), the Horsetail family was the dominant plant group in the world, with plants reaching gigantic size. Two basic forms of horsetails survive today. One is the hollow,...
Yellow toadflax (Linaria vulgaris) and Dalmatian toadflax (Linaria
dalmatica) are members of the figwort (Scrophulariaceae) family.
They were introduced into North America as ornamental plants because of their showy, snapdragon-like flowers. Yellow toadflax was brought from Wales in the mid-1800s as a garden flower by Ranstead, a Welsh Quaker who...
Squarrose knapweed, introduced from southwest Asia and the Middle East, became weedy in northern California and Utah by the early 1950s. How it
was originally introduced is not known, but its spread in California
and Utah was associated with the trailing of range sheep. Squarrose knapweed grows in the Klamath,...
Fertilizing hops improves yield and quality by supplying the crop with ample nutrition in advance of demand. Producers must combine this goal with production costs and environmental stewardship. Fertilization should be based on yield and quality response, experience, and economics. Unfortunately, limited experimental data exist linking modern cultural practices, current...

Yellow starthistle (Centaurea solstitialis L.) is a member of the knapweed
(Centaurea L.) complex. It is poor forage for all livestock and causes
“chewing disease,” a nervous disorder, in horses. Yellow starthistle infests

from scattered plants to dense stands...

The term "forest health" is being increasingly used in the context of forestry and natural resource management. For example, the term has been the subject of several articles in the JOURNAL oF FORESTRY and a recent Society of American Foresters task force report, Sustaining Long- 7•rm Forest Health and Productivity...
Blue mustard (Chorispora tenella) is a native of Russia or
southwest Asia. It first was documented in this country in
Lewiston, Idaho in 1929, and has spread throughout the
western plains states, the western portion of the United States,
and southern Canada.
Despite its widespread use, forest health is frequently used without a clear definition, making its application to forest management difficult. Where the term has been defined (McIntire 1988, Monnig and Byler 1992, USDA Forest Service 1992, USDA Forest Service I993a), alternative definitions and viewpoints of forest health have not been...
Bulbous bluegrass is another example of an introduced
European plant that escaped to become weedy. The first reports
of its growth in the United States were experimental
plantings at Arlington, Virginia, in 1907, and one at Pullman,
Washington, at about the same time. It was produced commercially
in southern Oregon...
