Evaluation of the environmental conditioning system as a water sensitivity test for asphalt concrete mixtures

Creator:: Allen, Wendy L.
Abstract:: The Environmental Conditioning System (ECS) was designed to evaluate the water sensitivity of asphalt concrete mixtures. The ECS subjects asphalt concrete specimens to a series of conditioning cycles including water flow, elevated and/or lowered temperature, and repeated axial loading. The purpose of this research was to: (1) evaluate the ECS...

Evaluation of water damage on asphalt concrete mixtures using the environmental conditioning system

Creator:: Al-Joaib, Ali Abdulla
Abstract:: Asphalt concrete pavement is subjected to several damaging actions from traffic loads, water (from precipitation and/or groundwater sources), and temperature. The durability of the asphalt-aggregate mixture, its ability to withstand these damaging actions for long periods, is a very important engineering property. While the durability of the asphalt-aggregates mixture depends...

Microelectrode Velocity Effects and Aquatic Eddy Covariance Measurements under Waves

Creator:: Reimers, Clare E., Özkan-Haller, H. Tuba, Albright, Andrea T., and Berg, Peter
Abstract:: Interest in validating the eddy covariance (EC) technique under wave-induced flows led to a series of experiments in a 104-m-long large wave flume (LWF) using an acoustic Doppler velocimeter (ADV) and two oxygen microelectrodes (tips ~2 mm apart) mounted on a sturdy tripod. Four additional ADVs positioned within the flume...

Measuring timber products harvested from your woodland

Creator:: Oester, Paul T., Bowers, S. (Steven Clay), and Oregon State University. Extension Service
Abstract:: This publication describes measurements used to buy and sell timber products. Managing woodland property offers you the opportunity to harvest a variety of products, depending on timber quality and quantity, harvest economics, and market availability. Among these products are saw logs, peeler logs, pulpwood, fuelwood, poles, piling, and posts. Knowledge...

Modeling Eddy Correlation Biases Created by Velocity Sensitivities of Clark-type Oxygen Microelectrodes Under Waves

Creator:: Albright, Andrea and Albright, Andrea T. P.
Abstract:: Field deployments, flume experiments, and a 2D wave model have been used to identify the characteristics of Clark-type oxygen microelectrodes and measurement parameters that could possibly bias eddy correlation (EC) flux measurements made under waves. Eddy correlation is a technique adapted from atmospheric sciences that couples concurrent and co-located velocity...

Benthic oxygen consumption rates during hypoxic conditions on the Oregon continental shelf: Evaluation of the eddy correlation method

Creator:: Reimers, Clare E., Özkan-Haller, H. Tuba, Berg, Peter, Devol, Allan, McCann-Grosvenor, Kristina, and Sanders, Rhea D.
Abstract:: Three stations, at ∼80 m water depth on the Oregon shelf between 44.7°N and 43.9 N, were studied under hypoxic conditions in late spring and summer of 2009 to determine benthic oxygen consumption rates. Oxygen fluxes were derived from eddy correlation (EC) measurements made from an autonomous lander deployed for...

Benthic oxygen consumption rates during hypoxic conditions on the Oregon continental shelf: Evaluation of the eddy correlation method

Creator:: Reimers, Clare E., Özkan-Haller, H. Tuba, Berg, Peter, Devol, Allan, McCann-Grosvenor, Kristina, and Sanders, Rhea D.
Abstract:: Three stations, at similar to ~80 m water depth on the Oregon shelf between 44.7 degrees N and 43.9 N, were studied under hypoxic conditions in late spring and summer of 2009 to determine benthic oxygen consumption rates. Oxygen fluxes were derived from eddy correlation (EC) measurements made from an...

Water content and electrical conductivity profile measurements for dispersive media using enhanced time domain and frequency domain models

Creator:: Flugstad, Benjamin A.
Abstract:: Water conservation and water quality are rapidly increasing in importance in all areas of the world. The ability to accurately measure soil water content and salinity, over a wide variety of conditions, is key to meeting this need. A set of forward prediction models and waveform interpretation algorithms to extract...

Effects of Fertilizer on Media Chemistry and Red-flowering Currant Seedling Growth Using a Subirrigation System

Creator:: Dunlap, Layla J., Pinto, Jeremiah R., and Davis, Anthony S.
Abstract:: Water conservation in nursery systems is an ever-increasing focus, yet there is relatively little guidance for growers producing seedlings intended for restoration regarding how practices such as subirrigation influence plant growth in the nursery and after outplanting. Our study investigated red-flowering currant (Ribes sanguineum Pursh) seedling development and early field...

Enhancement of thiamin in plants by metabolic engineering

Creator:: Dong, Wei, Stockwell, Virginia O., and Goyer, Aymeric
Abstract:: Thiamin is an essential nutrient in the human diet. Severe thiamin deficiency leads to beriberi, a lethal disease which is common in developing countries. Thiamin biofortification of staple food crops is a possible strategy to alleviate thiamin deficiency-related diseases. In plants, thiamin plays a role in the response to abiotic...
