Behavioral Thresholds in Mixtures of Sand and Kaolinite Clay

Creator:: Simpson, D. C. and Evans, T. M.
Abstract:: Nearly all soils are comprised of mixtures of coarse and fine particles. Behavior under mechanical and thermal loading of soil is strongly influenced, and in some cases governed, by the ratio of coarse to fine particles. A better understanding of the fundamental behavior of soil mixtures will provide insight to...

Behavioral thresholds in mixtures of sand and clay

Creator:: Simpson, Daniel Corder
Abstract:: Nearly all soils are comprised of mixtures of coarse and fine particles. Behavior under mechanical and thermal loading of soil is strongly influenced (and in some cases, governed) by the ratio of coarse to fine particles. A better understanding of the fundamental behavior of soil mixtures will provide insight to...

Mid-Nineteenth Century Clay Smoking Pipes from Fort Hoskins (35BE15) and Fort Yamhill (35PO75), Oregon

Creator:: Zentgraf, Diane M.
Abstract:: Over the past 42 years clay smoking pipes have been excavated from two U.S. army posts, Fort Hoskins (35BE15) and Fort Yamhill (35PO75) and curated at Oregon State University. These two forts were established in Western Oregon in 1856 and by 1866 both had been decommissioned. Numerous theses have focused...

Effect of Particle Shape on Stress-Dilatancy Responses of Medium-Dense Sands

Creator:: Xiao, Yang, Long, Leihang, Evans, T. Matthew, Zhou, Hai, Liu, Hanlong, and Stuedlein, Armin W.
Abstract:: The effect of particle shape on the strength, dilatancy, and stress-dilatancy relationship was systematically investigated through a series of drained triaxial compression tests on sands mixed with angular and rounded glass beads of different proportions (0%, 25%, 50%, 75%, and 100%). A distinct overall regularity parameter was used to define...

Near-Surface Response of Beach Sand : An Experimental Investigation

Creator:: Adams, Rachel Katie
Abstract:: The near-surface region of a coastal sediment bed is complex and dynamic. At some sites, near-surface sediment deposits are susceptible to extreme events, such as tsunamis or other large overflows, which induce high shear stresses on the sediment bed. The specific properties of sediment beds subjected to such extreme loading...

Munition Mobility in Mixed Grain (Sand and Cobble) Environments

Creator:: Paskoski, Jessica
Abstract:: Nearly 24% of Formerly Used Defense Sites (FUDS) containing military munitions are in the nearshore coastal zone with approximately 30% of those sites containing heterogeneous sediment compositions of gravel-sand. Previous exploration in munition mobility was performed on beaches of sandy or muddy bottoms leaving the influence of heterogeneous sediment properties...

Assessing Exposures and Simplifying Complex Mixtures of SVOCs for Hazard Characterization using Alternative Model Systems

Creator:: Rivera, Brianna N.
Abstract:: Throughout their lifetime individuals are exposed to complex mixtures of chemicals. The study of chemical mixtures is an internationally recognized research priority, but seemingly complex challenge. To reduce the intricacy of studying mixtures, researchers have identified different prioritization methods based on exposure or the toxicity of chemicals. However, understanding the...

A Comprehensive Mechanistic Study on Using Fine Lightweight Aggregate to Mitigate Alkali-silica Reaction

Creator:: Li, Chang
Abstract:: Previous research has shown that using fine lightweight aggregate (FLWA) can be a promising strategy to mitigate alkali-silica reaction (ASR) in mortar and concrete. While several possible theories were proposed by researchers, discrepancies in testing methods, materials, and supporting evidence still exist. Therefore, this study was initiated. There are two...

Urban and rural-residential land uses : their role in watershed health and the rehabilitation of Oregon's wild salmonids

Creator:: Independent Multidisciplinary Science Team
Abstract:: Urban areas currently cover a small fraction of Oregon’s landscape but will expand to accommodate an increasingly large proportion of the state’s growing population and economic activity. Residential developments on rural lands now cover more than twice the area occupied by Oregon’s urban developments and are growing rapidly. Oregon urban...
