The control and fate of enteric bacteria in the environment with particular emphasis on the factors influencing fecal indicator survival in waste storage facilities

Creator:: Crane, Stuart R.
Abstract:: The indiscriminate release of fecal bacteria to the environment can present a public health hazard when pathogenic species gain access to drinking and recreational water sources. The extent of bacterial contamination of surface and ground waters associated with animal production units and waste application areas seems largely dependent on the...

Finite Element Modeling Strategies for Seismic Collapse Assessment of Non-planar Slender Reinforced Concrete Structural Wall Resisting Systems

Creator:: Mohammed, Mohammed A.
Abstract:: For mid-rise and high rise buildings, slender reinforced concrete (RC) structural walls are commonly used as the main structural elements to resist lateral applied loads in high seismically areas around the globe. These RC structural walls can provide substantial deformation capacity, stiffness, and lateral strength through the contribution of their...

Mechanics and movement of the Lookout Creek Earthflow

Creator:: Mills, Keith A.
Abstract:: The Lookout Creek Earthflow is located in the Cascade Mountain Range in western Oregon. The Cascade Mountains are mainly volcanic in origin, and deposits in and around the slide have a complex geomorphic history,, affected by glacial, mass movement, and fluvial processes. The currently moving land mass is about 1600...

Chemical characterization of asphalt cements using chromatographic techniques : relation to rheological properties and field performance

Creator:: Thenoux, Guillermo
Abstract:: This dissertation presents the findings of a literature review and information regarding selection, implementation and development of a chemical composition procedure for asphalt cements. The chemical composition analysis selected was the Corbett-Swarbrick procedure standarized as ASTM D4124. The procedure is a selective adsorption / desorption (solid / liquid) chromatography which...

Permanent deformation characteristics of dense-graded mixes using asphalt pavement analyzer

Creator:: Sandoval-Gil, Jesus A.
Abstract:: The Asphalt Pavement Analyzer (APA) device was used to characterize the impact of various mix factors on the development of permanent deformation in dense-graded mixes given a standard compactive effort. Factors included two aggregate sizes, three VMA levels, two fines contents, three binder contents and four binder types. All specimens...

Coupled Eulerian-Lagrangian Finite Element Modeling Approach Applied to Wave Structure Interaction: Effects of Shielding, Channeling, and Wall Removal

Creator:: Al-Sayhood, Zeyad A.
Abstract:: The impact of tsunamis on coastal structures gained great a new impetus following the 2004 Indian Ocean Tsunami and the 2011 Tohoku earthquake and tsunami. While several experimental programs have been performed to gain a fundamental understanding, numerical models are needed to study additional features that cannot all be tested...

Modeling of ammonia losses in sprinkler application of animal wastes

Creator:: Pote, Jonathan W. (Jonathan Woodrome)
Abstract:: A model to predict ammonia losses from sprinkler applied animal wastes was developed; in order to accomplish this, a review of literature was performed to determine possible methods of predicting ammonia losses during sprinkling. As adaptability to a large variety of situations was considered of maximum importance, the number of...

Bond strength investigations and structural applicability of composite fiber-reinforced polymer (FRP) rebars

Creator:: Kachlakev, Damian I.
Abstract:: The composite FRP rebars research at Oregon State University was initiated in 1993 principally to develop a non-metallic hollow reinforcement. It was recognized that the tensile properties of such reinforcement are unquestionably superior to steel, but its performance in concrete could be problematic. The bond between FRP rebars and concrete...

Early age performance of latex-modified concrete bridge deck overlays

Creator:: Sujjavanich, Suvimol
Abstract:: Environmental factors and physical properties of latex modified concrete (LMC) are hypothesized to contribute to early age cracking in bridge deck overlays. Cracking permits the ingress of moisture and aggressive solutions into the substrate and may contribute to other subsequent distresses. Understanding the material properties and mechanisms involved is necessary...

Pull-Oriented Faculty Development: A Multiple, Descriptive-Explanatory Case Study

Creator:: Barner, Matthew S.
Abstract:: Traditional faculty development programs aimed at disseminating research-based pedagogy and innovations at potential adopters have helped increase awareness of these innovations; however, their adoption into engineering classrooms has been limited. This paper aims to present an alternative, pull-oriented approach to faculty development where faculty participants co-develop curricular innovations with engineering...
