Weed Management, Training, and Irrigation Practices for Organic Production of Trailing Blackberry : Plant Growth, Yield, and Nutrients

Creator:: Dixon, Emily K.
Abstract:: There is limited information available on production of trailing blackberry, particularly certified organic plantings, which are of interest to growers as there is increased consumer demand and a price premium over conventionally-produced fruit. Various production strategies were evaluated for their effect on yield, biomass production, carbon (C), and nutrient concentrations...

Dietary soy and green tea in the prevention of prostate cancer

Creator:: Hsu, Anna
Abstract:: Prostate cancer risk is significantly lower in Asian countries compared to the US, which has prompted interest in the chemo-preventative action of dietary components such as soy and green tea commonly found in Asian diets, such as soy and green tea. Studies have suggested that soy isoflavones and green tea...

Weed Management, Training, and Irrigation Practices for Organic Production of Trailing Blackberry: II. Soil and Aboveground Plant Nutrient Concentrations

Creator:: Dixon, Emily K., Strik, Bernadine C., and Bryla, David R.
Abstract:: Organic production of blackberries is increasing, but there is relatively little known about how production practices affect plant and soil nutrient status. The impact of cultivar (Black Diamond and Marion), weed management (nonweeded, hand-weeded, and weed mat), primocane training time (August and February), and irrigation (throughout the summer and none...

Weed Management, Training, and Irrigation Practices for Organic Production of Trailing Blackberry: III. Accumulation and Removal of Aboveground Biomass, Carbon, and Nutrients

Creator:: Dixon, Emily K., Strik, Bernadine C., and Bryla, David R.
Abstract:: Relatively little is known about aboveground nutrient content of organic blackberry, and there is no published work on total carbon (C) content. Treatment effects on biomass, C, and nutrient content, accumulation, and removal were assessed over 2 years in a mature organic trailing blackberry (Rubus L. subgenus Rubus, Watson) production...

Why do Trees Stop Getting Taller? Team tests treetop turgor to find an answer

Creator:: Thomas, Emily
Abstract:: Scientists use a large crane to gather samples from the tops of trees. These samples will be tested for turgor in an attempt to explain why trees stop growing. Featuring Dr. Barbara Bond, Dr. Rick Meinzer, and R.A. Dave Woodruff.

Managing for landscape resilience in the frequent-fire forests of central Oregon

Creator:: Platt, Emily K.
Abstract:: Wildfire in dry, frequent-fire forests is a pressing issue for natural resource managers, communities and politicians in the western United States. Area affected by wildfire has climbed steadily over the last twenty years and is expected to increase in the future. Recognition of the importance of both social and biophysical...

Effectiveness of curve advisory speed signs : a characterization of road operations in western Oregon

Creator:: Avelar Morán, Raúl Eduardo
Abstract:: Posting advisory speed signs at sharp horizontal curve locations is a common practice in the U.S. These signs recommend drivers safe speeds to negotiate such curves. Literature indicates that adherence to advisory speeds is, in general, poor. Moreover, limited research is available that quantifies safety implications of these signs. This...

Safety performance of curve advisory speed signs

Creator:: Avelar Moran, Raúl Eduardo
Abstract:: Posting advisory speed signs at sharp horizontal curve sites is a practice well established in the United States. The purpose of these signs is to provide the driving public with a safe speed to negotiate such curves; however, the link between these signs and safety has not yet been clearly...

Optimal sensor placement for measuring operating speeds through curves on rural two-lane highways

Creator:: Mecham, Megan E.
Abstract:: Operating speed is one of the best performance measures that can tell transportation agencies how well or how poorly the transportation system is functioning. Fluctuating operating speeds often mean there is a design flaw or something about the physical road design that violates drivers' expectations. A primary example of this...

A validation of the Oregon State University driving simulator

Creator:: Brown, Lacy S.
Abstract:: Driving simulation is widely accepted as a safe, effective, and economical alternative for investigating driver behavior in a variety of contexts. However, in order to apply simulator-based research results to real-world settings, the performance measures acquired through simulated driving experiments must first be validated. This research was aimed at validating...
