Benthic foraminiferal δ¹³C data from site 502 in the Caribbean Sea (sill depth 1800 m) indicate that throughout the past 2.6 m.y., glacial δ¹³C values in the middepth Atlantic were higher during glaciations than interglaciations. This is interpreted as indicating a greater proportion of Upper North Atlantic Deep Water (UNADW)...
The adsorption equilibrium and kinetic behavior exhibited
by β-lactoglobulin at silanized silicon surfaces of varying
hydrophobicity were examined using ellipsometry. Adsorption
equilibrium results were used to construct adsorption
isotherms; the adsorbed mass of β-lactoglobulin was observed
to increase with increasing surface hydrophobicity, within a
defined range of hydrophobicity. Adsorption kinetics...
Ellipsometry was used to study the effects of surface energetics
and temperature on the equilibrium adsorptive behavior exhibited by
β-lactoglobulin. β-Lactoglobulin isotherms at 25, 37, and 55°C were
constructed for this purpose. The surfaces of acrylic, polycarbonate,
polyester, glass, and #304 stainless steel were contacted with protein
solutions of varying...
Zora Neale Hurston was a Black American writer

Cytokinins are a group of plant hormones mediating cell division and
differentiation. Zeatin is a naturally occurring and highly active cytokinin that is rapidly
metabolized in Phaseolus seeds. The metabolites and enzymes mediating the conversion

Ports in the United States have a special relationship to their local economies. They frequently have more economic development authority than other municipalities and are significantly affected by international and national as well as local economic events. This publication is intended to help you understand your port's role in your...
Harvesting costs were determined for commercial thinning of young stands to
achieve vegetation and wildlife objectives. This included replicated comparisons of
thinning treatments. Treatments were defined based on residual tree stocking after
thinning. Study procedures were developed and evaluated to improve statistical

Many parents want their children to have positive feelings about themselves and to believe they can succeed. Children often evaluate their selfworth and make judgments about their abilities based on experiences they have at home. Families can provide numerous
opportunities every day to develop children’s self-confidence.
Why is problem solving important for families? Naturally, conflicts arise
for children every day. Children who learn to figure out solutions
to their problems are better able to work and play with others. The
ability to solve difficult situations also builds positive self-esteem,
self-confidence, and relationships with others.
Children are naturally curious and have a strong desire to
be independent. They may go beyond the rules and limits
parents set. Sometimes parents aren’t sure how to respond to
children’s behavior. Parents may react angrily, rather than warmly
In the Pacific Northwest, a transition has begun that is shifting many practices in forest management. Traditionally, harvesting and regeneration has been done through clearcutting which removes all trees in the area being cut and plants an entirely new stand. Clearcutting is often the most efficient method for harvesting forests...
Variability in fruit set and yield is a serious problem in Oregon viticulture, particularly with Pinot noir.
Climatic variation during the flowering period contributes significantly to this problem by affecting fruit
set and cluster weight. Cool wet weather during bloom results in poor set, small clusters, and low yields.
In the past ten years, variation in Oregon vineyard yields has come from two main causes: winter injury and inconsistent fruit set. Together these factors have caused significant yield variation in almost every Oregon vineyard. In 1991, a research project was started at Oregon State to develop and evaluate a...
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...
Yellow starthistle (Centaurea solstitialis L.) is a member of the knapweed

from scattered plants to dense stands...

Several effects of xylem discontinuity in Pinot noir
and Merlot grape berries were studied. There was a
reduction in the amount of apoplastic dye (Eosin Y or
azosulfamide) uptake through cut pedicels into soft

xylem flow at that time. Both greenhouse and...

Like other social institutions, universities have been
created and administered by and for a white-male dominant
culture that continues to marginalize women and anyone else
designated as -Other- according to race, class, ethnicity,
ability, age, size, and sexuality. This discussion

The classroom practices discussed in this thesis come slowly and at a "slant" to feminism through critical reading of texts, a practice that I call a (re)presentation of the silent women in texts.

With indications that fisheries production has plateued at a global capacity of 85 million metric tons in the 1990's, further exploitation of marine stocks on a sustainable basis is unrealistic.

I studied selection of winter den sites by northern flying squirrels (Glaucomys sabrinus) in forests of the Oregon Cascades. Fifty-six squirrels were radio-collared in three managed, 80- to 1 30-year-old Douglas-fir stands on the Umpqua Nationa Forest during the winters of 1994-95 and 1995-96. Squirrels were located at their den...
