Anomalous Diffusion of Sand Tracer Particles Under Waves

Creator:: Wilson, Gregory W.
Abstract:: A model is presented for the horizontal and vertical diffusion of sand tracer particles by waves and is verified using a reanalysis of the experiments of Miller and Komar (1979, ). In the model, sand particles take random jumps at a rate associated with the wave period but also can...

Professional Decisions: The Central Role of Models

Creator:: Elms, David G. and Brown, Colin B.
Abstract:: Engineering is largely concerned with models and modelling. Models provide a context in which decisions are made. Here the modelling process is considered in a general sense and then the relationship with engineering models is developed. For understanding, a first step is to differentiate and categorize. Thus ten types of...

Professional Decisions: Responsibilities

Creator:: Elms, David G. and Brown, Colin B.
Abstract:: The responsibilities which civil engineers, and particularly the engineer of record, accept are considered. The interaction with other decision makers such as the owner, stakeholders, the law and contractors results in complexity that can be partially resolved by the introduction of protocols in the form of regulations and codes of...

Post-fire logging produces minimal persistent impacts on understory vegetation in northeastern Oregon, USA

Creator:: Peterson, David W. and Dodson, Erich Kyle
Abstract:: Post-fire forest management commonly requires accepting some negative ecological impacts from management activities in order to achieve management objectives. Managers need to know, however, whether ecological impacts from post-fire management activities are transient or cause long-term ecosystem degradation. We studied the long-term response of understory vegetation to two post-fire logging...

Estimating the Counterfactual Impact of Conservation Programs on Land Cover Outcomes: The Role of Matching and Panel Regression Techniques

Creator:: Jones, Kelly W. and Lewis, David J.
Abstract:: Deforestation and conversion of native habitats continues to be the leading driver of biodiversity and ecosystem service loss. A number of conservation policies and programs are implemented—from protected areas to payments for ecosystem services (PES)—to deter these losses. Currently, empirical evidence on whether these approaches stop or slow land cover...

Seasonal cues induce phenotypic plasticity of Drosophila suzukii to enhance winter survival

Creator:: Shearer, Peter W., West, Jessica D., Walton, Vaughn M., Brown, Preston H., Svetec, Nicolas, and Chiu, Joanna C.
Abstract:: Background: As global climate change and exponential human population growth intensifies pressure on agricultural systems, the need to effectively manage invasive insect pests is becoming increasingly important to global food security. Drosophila suzukii is an invasive pest that drastically expanded its global range in a very short time since 2008,...

Shared compatibility of ectomycorrhizae on Pseudotsuga menziesii and Betula papyrifera seedlings grown in mixture in soils from southern British Columbia

Creator:: Simard, Suzanne W., Molina, Randy, Smith, Jane E., Perry, David A., and Jones, Melanie D.
Abstract:: Seedlings of Pseudotsuga menziesii (Mirb.) Franco and Betula papyrifera Marsh. were grown in the greenhouse in monoculture and dual culture in soils collected from a young mixed species plantation in the southern interior of British Columbia. The objectives of the study were (i) to evaluate the ability of P. menziesii...

Creator:: Kannberg, Peter K., Tréhu, Anne, Pierce, Stephen D, Paull, Charles K, and Caress, David W.
Abstract:: While bubble plumes have been acoustically imaged in the water column above marine gas hydrate deposits in many studies, little is known about the temporal variation in plume intensity. In July 2008, we conducted surveys using 3.5 and 12 kHz echosounders and a 75 kHz acoustic Doppler current profiler (ADCP)...

Knapweed Hay as a Nutritional Supplement for Beef Cows Fed Low-Quality Forage

Creator:: Bohnert, David W., Sheley, Roger L., Falck, Stephanie J., and Nyman, Arthur A.
Abstract:: Advancing our ability to use invasive plants for producing commodities is central to the agricultural industry. Our objective was to evaluate Russian knapweed (Acroptilon repens [L.] DC.) as a winter feed supplement for ruminant livestock. In Experiment 1, we utilized three ruminally cannulated steers in a completely randomized design to...

Characterization of inverse diffusion flames in vitiated cross flows via two-photon planar laser-induced fluorescence of CO and 2-D thermometry

Creator:: Richardson, Daniel R., Jiang, Naibo, Blunck, David L., Gord, James R., and Roy, Sukesh
Abstract:: Two-photon, planar laser-induced fluorescence (PLIF) of carbon-monoxide (CO) and two-dimensional thermometry employing two-color, hydroxyl radical (OH) PLIF are used to characterize atmospheric-pressure inverse diffusion flames. These flames are important tools to aid the understanding of secondary reaction zones that may form in gas turbine engines when film-cooling air reacts with...
