A wireless power transfer system using inductive coupling was designed and implemented as part of a three-member project team. The system uses coupled magnetic fields at a frequency of 606kHz to transfer electromagnetic energy from a charging base to the batteries of portable devices. It succeeded in transmitting power to...
Over 70% of the Antarctic krill population exists along the Antarctic Peninsula, a region undergoing rapid climate change. Recent studies have shown a clear correlation between krill recruitment each spring and the timing and coverage of sea ice the winter before, with less sea ice and a shorter duration being...
Krascheninnikovia lanata (winterfat) is a valuable forage species with an
average of 10% crude protein during winter when there are few nutritious options for
livestock and wildlife. However, excessive grazing throughout the west has negatively
impacted survival of winterfat stands. We hypothesized that four years rest from
dormant season livestock...
Recommendations in this fertilizer guide apply to tillage fallow-winter wheat and chemical fallow-winter wheat cropping systems. This guide is one of a set of publications that address the nutritional requirements of nonirrigated cereal crops in north-central and eastern Oregon.
Recommendations for nitrogen, phosphorus, potassium, sulfur, chloride, and zinc are covered...
Recommendations in this guide apply tocontinuously cropped cereals in low-
precipitation zones. This guide is one of a set of publications that address the nutritional requirements of nonirrigated cereal crops in north-central and eastern Oregon. Recommendations for nitrogen, phosphorus, potassium, sulfur, chloride, and zinc are covered in this guide. Soils...
Winter squash is an important late winter vegetable crop for local and regional markets; however, farmers in western Oregon report that this crop is marginally profitable due to losses in storage and relatively low yields for the high culinary value kabocha and buttercup types. In order to increase the sales...
Information on winter marine bird and mammal distributions in Oregon coastal waters has been identified as a data need for marine spatial planning of ocean energy development. As part of the annual marine mammal surveys of the critical habitat for Endangered Species Act (ESA)-listed Southern Resident Killer Whales (Orcinus orca),...
Concise information on the basics of managing livestock in winter, including use of sound production practices. Particularly for the region east of the Cascade Mountains. Companion audio files describe:
audio4: Winter Livestock Care. How to keep your animals healthy in inclement weather, through shelter, feeding, and water access.
audio5: All...

Winter grain mite, Penthaleus major (Duges), is a small, colorful, cool season mite that damages grass and cereal crops throughout the Pacific Northwest as well as in most other temperate regions of the world. Hosts include most cereals and grasses of economic importance. Winter grain mite has been a frequent...
Responses of biological indicators of soil quality to winter cover cropping were measured on soil samples collected from 6 commercial growers' fields and two experiment research stations in the Willamette Valley of Oregon. The research stations were the North Willamette Research and Extension Center (Aurora, OR), and the Oregon State...
