Forest Fire Effects on Radiative and Turbulent Fluxes over Snow : Implications for Snow Hydrology

Creator:: Gleason, Kelly E.
Abstract:: As a result of a warming climate, subsequent declining snowpack, and a century of fire suppression, forest fires are increasing across the western United States. However, we still do not fully understand how forest fire effects snowpack energy balance, nor the volume and availability of snow melt and associated water...

Flexural anchorage performance and strengthening on negative moment regions using near-surface mounted retrofitting in reinforced concrete bridge girders

Creator:: Barker, Laura
Abstract:: Large numbers of reinforced concrete deck girder (RCDG) bridges were built during the highway infrastructure boom of the 1950's. The advent of standardized deformed steel reinforcing bars during this time allowed for straight bar terminations in flexural tension regions. Designers of the time terminated reinforcing bars where they were no...

Defining one’s role in citizen science: an exploration of the roles, perceptions and outcomes of participation in citizen science activities

Creator:: Clarke, Karl
Abstract:: Citizen science (formally public participation in science research) has emerged in recent years as an innovative and interactive tool for engaging many diverse groups in science and research. Defined as the collaboration of science professionals and the public in science research, citizen science has tremendously improved the reach of science....

High frequency water vapor density measurements using the beat frequency method

Creator:: Elorriaga Montenegro, Estefania
Abstract:: This document describes the design and deployment of a first generation water vapor density sensing unit, the HumiSense. This device is based on an open, air-filled capacitor which is part of a resonant circuit. The frequency of the resonant circuit mixed with a fixed frequency oscillator is the basis of...

Behavior and analysis of pile caps with poor anchorage details

Creator:: Sorentino, Anthony William
Abstract:: Pile caps are structural elements used to transmit loads from structural columns into pile groups. A pile cap is generally constructed of reinforced concrete and contains only minimal flexural reinforcing steel. Using modern design methods, the anchorage of the flexural steel may limit the design capacity of existing pile caps....

Comparison of radiative feedback variability over multiple time scales in climate model and reanalysis data

Creator:: Dalton, Meghan M.
Abstract:: In a steady state, the Earth's absorbed solar radiation (ASR) balances the outgoing longwave radiation (OLR) at the top of the atmosphere (TOA). In response to a radiative forcing, that is, an external perturbation to the top of the atmosphere energy balance, the Earth's climate system adjusts until reaching a...

Initial performance assessment for implementation of hot mix asphalt containing recycled asphalt shingles in Oregon

Creator:: Samoo, Faisal Ahmed
Abstract:: This thesis documents the evaluation of the initial performance of pavement containing recycled asphalt shingles (RAS) in Oregon. The research was funded by the Oregon Department of Transportation (ODOT) and the Federal Highway Administration and was conducted at Oregon State University. The key objectives of this thesis are to document...

Antimicrobial peptide regulation by small molecules in humans and other primates

Creator:: Sinnott, Brian D.
Abstract:: Antimicrobial peptides (AMPs) play an important role in the innate immune system. Determining the pathways by which these proteins are regulated allows for modulation of their expression for better health. Two families of antimicrobial peptides have been studied in humans: cathelicidins and defensins. There is a single cathelicidin in humans...

Contact and impact dynamic modeling capabilities of LS-DYNA for fluid-structure interaction problems

Creator:: Challa, Ravi
Abstract:: Fluid-structure interaction (FSI) is a very interesting and challenging multi-disciplinary field involving interaction of a movable or deformable structure with an internal or surrounding fluid flow. FSI plays a pivotal role in many different types of real-world situations and practical engineering applications involving large structural deformation and material or geometric...
Resource Type:: Masters Thesis

Evaluation of transgenes for stress tolerance, lignin modification, and growth enhancement in poplar

Creator:: Elias, Ani Anna
Abstract:: We evaluated genes previously identified from a large scale functional genomics screen for their potential value to help enhance carbon sequestration in planted trees. We used poplar as a model tree species because of its abundant genetic variation, ease of gene transfer, and availability of large databases for genomic, anatomical,...
