The twospotted spider mite, Tetranychus urticae Koch (Acari: Tetranychidae), is a
worldwide pest of numerous agronomic and horticultural plants. Conservation
biological control of this pest can be unreliable due to asynchrony of natural enemies
and certain horticultural practices that have a direct or indirect affect on natural
enemies and the...
This investigation was a two stage study performed in two urban/
rural communities in Washington State. Stage I was an effort to replicate a study performed in an eastern Virginia school district whereby
results were obtained demonstrating that 9th graders and black students
identified teacher warmth behaviors as being important...
Wood stiffness is one of the most important properties of lumber and veneer. We studied wood stiffness (modulus of elasticity, MOE), wood density, microfibril angle, and knots in a 25 year-old wind pollinated progeny test (50 families, ~ 373 trees) of coastal Douglas-fir to understand the potential for genetically improving...

Wood modulus of elasticity (MOE), also known as wood stiffness, is one of the most important wood properties. Wood stiffness is a measure of the resistance to deflection, and is important because some products such as laminated veneer lumber, plywood, and dimension lumber require stiff and strong wood. Incorporating wood...

The purpose of this annotated bibliography is to guide middle school and high school students into critical thinking about environmental issues. Through keen observation of their bioregion and through an integration of interdisciplinary literature which focuses on Oregon writers, students will be challenged to think, write, and discuss current issues...
Foresters care about site productivity and stem quality in Douglas-fir plantations for many reasons. The profitability of forest land and the economic returns on silvicultural investments are directly related to site productivity. Thus, understanding the relationships among Douglas-fir productivity, stem form and site characteristics is important economically. My objective was...
In twentieth century America, women continue the age-old struggle for recognition
as whole, intelligent individuals, not just an "other," less hearty, less deserving
or less capable being than man. Sarah Grimke spoke of the inequalities over 150 years
ago during the abolitionist movement when she compiled her major arguments into...
Moisture durability is essential for wood composites, especially those used in building construction, where products are prone to weathering. The primary focus of this research was to determine if adhesive penetration into the cell wall has a positive influence on adhesive bond durability. To fully understand the measureable effects of...
