Methods to improve the reliability and resiliency of near/sub-threshold digital circuits

Creator:: Crop, Joseph A.
Abstract:: Energy consumption is one of the primary bottlenecks to both large and small scale modern compute platforms. Reducing the operating voltage of digital circuits to voltages where the supply voltage is near or below the threshold of the transistors has recently gained attention as a method to reduce the energy...

Specification of local surface weather elements from large-scale general circulation model information, with application to agricultural impact assessment

Creator:: Wilks, Daniel S.
Abstract:: A procedure for model-assisted climate impact assessment is developed. The approach combines data from observations and atmospheric general circulation models (GCNs), and provides the basis for a potentially valuable means of using information derived from GCMs for climate impact assessments on local scales. The first component of this procedure is...

Visualization in environmental science

Creator:: Winters, Kirsten M.
Abstract:: The VISualization of Terrestrial and Aquatic Systems (VISTAS) software development project began with the proposition that visualization would increase the ability of scientists to explore and communicate their data, especially complex datasets that span multiple spatial and temporal scales. A case study of VISTAS articulates how and why scientists intend...

Effect of nitrogen and water stresses during tillering and grain- filling in wheat

Creator:: Ashraf, Muhammad, 1952-
Abstract:: The CERES-Wheat Crop Growth and Development model treats temperature, nitrogen and water stresses as limiting factors. For each day the model calculates a stress index for temperature, N and water, compares the magnitude of the indices, and then adjusts the calculated daily potential growth using the index of the most...

Spring establishment of orchardgrass and tall fescue seed crops with cereal companion crops

Creator:: Chastain, Thomas G.
Abstract:: Orchardgrass and tall fescue seed crops are commonly springplanted in Oregon, but do not produce a marketable crop during the first growing season. Establishing orchardgrass and tall fescue with cereal companion crops would provide income during the seeding year and could increase seed production profits. This study was conducted to...

Cover crops and biochemical functional diversity in relation to nitrogen availability in soil

Creator:: Burket, John Zimmerman
Abstract:: Nitrogen availability in agricultural soils from fertilizer, plant residue inputs, and soil organic matter has important implications beyond crop yield. Legume winter cover crops and one fourth the recommended N rate on sweet corn resulted in yields equivalent to those at the recommended rate in the Willamette Valley of western...

Foliar interception and uptake of ³⁶Cl by crops

Creator:: Bytwerk, David Paul
Abstract:: Greenhouse studies were conducted to determine interception, absorption, and translocation values for foliar applied ³⁶Cl. Foliar interception and uptake of contaminated irrigation water by crops is a major pathway for the transport of radionuclides to human beings in scenarios relevant to the waste disposal community. Performance assessments of many repositories...

Physiological responses of creeping red fescue to stubble management and plant growth regulators

Creator:: Meints, Paul David
Abstract:: Legislation to reduce open field burning in grass seed fields within the Willamette valley of western Oregon changed established production practices. In the creeping grasses such as Kentucky bluegrass (Poa pratensis L.) and creeping red fescue (Festuca rubra L.) non-thermal management resulted in reduced yield. Studies were conducted to examine...

Nitrogen partitioning and remobilization in field-grown apple trees

Creator:: Khemira, Habib
Abstract:: Uptake and cycling of nitrogen (N) in mature trees are not well understood. Fertilizer-N uptake, partitioning, and use-efficiency were studied in standard strain 'Topred Delicious' and spur strain 'Redspur Delicious' mature apple trees {Malus domestica Borck) on 'Malling 7A' (M.7A) rootstocks. The treatments consisted of a ground application in spring,...

Science education in a Philippine village

Creator:: Brush, Edwin Graham
Abstract:: Research was undertaken to describe the teaching and learning of science in a non-Western village with particular attention paid to cultural parameters. Cognitive elements in a Philippine (Tagalog) village and school were analyzed. The local language was studied for its capacity of transmitting scientific information. Verbal interaction in the science...

Water relations in red and white clover seed crops

Creator:: Oliva, Ruben N.
Abstract:: Both red (Trifolium pratense L.) and white (Trifolium repens L.) clover seed yields can be highly variable and low in western Oregon. The objectives of this study were to: i) determine crop water requirements and supplemental irrigation timing, and ii) quantify the effects of soil and water status on inflorescence...

Nutrient management and cycling in grass seed crops

Creator:: Horneck, Donald Arthur
Abstract:: Grass seed production in Oregon's Willamette Valley traditionally relied on open field burning for straw residue disposal and nutrient recycling. Changes in residue management from open field burning to methods that remove straw coincided with rapidly declining K soil test values. A survey of grass seed fields showed that many...

An evaluation of soil warming for increased crop production

Creator:: Rykbost, K. A.
Abstract:: In regions where soil temperatures limit plant growth, artificial soil warming may be an economically feasible practice. This hypothesis was evaluated in a soil warming experiment near Corvallis, Oregon. This experiment was prompted by the observation that multiple use of waste heat discharged in the condenser cooling water of thermal...
