The data retrieved from gt;momic sequencing techniques provides the raw information required to infer the basis of mutations and their resulting phenotypes, wherein plant ontologies can be utilized in annotating said phenotypes using a common, shared vocabulary. By relating mutant genes of similar phenotypes both within and between plant species,...
This project describes the investigation of marine cyanobacteria collected from the Red Sea with an emphasis on the identification and prioritization of biologically active fractions for future purification and molecular structure elucidation of medicinally relevant secondary metabolites.
Five crude extracts of taxonomically unidentified Red Sea cyanobacteria supplied by Egyptian collaborators...
Recent studies have shown that novel continuous dropout methods can be viewed as a Bayesian interpretation of model parameters, though most such studies have shown results using normal distributions. As the posterior distributions over neural network nodes and parameters are intractable, given that they are a result of artificial construction...
This thesis describes the implementation of ultrasonic sensors to trigger a stimulus to increase peer interaction for children with disabilities using modified ride-on-cars for mobility. Modified ride-on-car technology has improved mobility for children with disabilities by effectively replicating the social benefits of a powered mobility device, yet there are opportunities...
Using X-ray computed tomography (CT) scanning to characterize the physical characteristics of soil and sediment cores allows scientists to observe and analyze stratigraphy without destroying the integrity of different layers. Microbiologists often work with geologists to characterize the microbial communities in such cores; however, X-rays are known to be destructive...
With the rise of resistant bacterial pathogens, currently prescribed antibiotics are rendered useless. In recent years, marine natural products (MNPs) have emerged as novel sources for drug leads. The ocean is a complex environment where marine animals cohabitate with many, and sometimes harmful microorganisms and viruses, but resist infections. Developed...
Heat flux measurements of radiation emissions from turbulent premixed flames diluted with N 2 and CO 2 were taken to identify sensitivities of radiation heat loss to diluent fraction and species. This work is motivated by the desire to better characterise radiant heat transfer in the presence of combustion products,...
Under the Paris Agreement, parties submitted documents outlining their commitments to climate change mitigation and adaptation, called Nationally Determined Contributions (NDCs), which are set to be updated to increase ambition by 2020. Costa Rica and México are known for their significant national actions on climate change, so comparing these two...
Chiropractic treatment is used to reduce stiffness and pain. While more thoroughly studied in humans, it has been shown to be effective in horses, but relatively little evidence exists to quantify the benefits. To address this shortcoming, four methods were used to assess the effects of chiropractic treatment in horses...
Electrochemical sensing provides a quantitative alternative to colorimetric reactions within paper-based devices. The paper-based devices were fabricated by screen printing the conductive and reference inks onto porous substrates that were evaluated using cyclic voltammetry. Devices were evaluated based on the magnitude of the average anodic peak height, which correlates with...
Stream light availability is an important factor influencing aquatic food webs. In forested headwaters, stream algal production is often highly light-limited, so an increase in light enhances benthic algal growth, which in turn increases food availability for primary consumers in the stream. In forested headwater streams, light availability is almost...
Oregon State laboratories are responsible for a significant portion of the university’s overall resource and energy consumption, and therefore minimizing waste in a sustainable way should be a top priority for the university while aiming for carbon neutrality by 2025. This study addresses major factors that should be considered when...
The relationship between a parent and child in the first years of life have a significant effect on the development of children. Parenting education can be a valuable resource for learning evidence-based parenting strategies, but access to parenting education is limited in many states. Oregon has a unique statewide system...
This research examined the potential for using peanut husk as a fiber alternative to wood in the production of melamine-formaldehyde (MF) particleboard. MF resin was used to produce panels with one, three, six, nine or 12 percent resin contents. Modulus of Rupture (MOR), Modulus of Elasticity (MOE), Internal Bond (IB)...
There is no shortage of challenges in modern science, including the task of obtaining high resolution images of biomolecular structures, such as proteins. Current atomic-resolution structure determination methods include x-ray crystallography and nuclear magnetic resonance (NMR), which present issues like protein crystallization and loss of resolution with increasing size. Dr....
This study sought to understand the commonality of vaccine misconceptions among college students and where individuals feel they are obtaining their vaccine information. An IRB approved survey was used to collect 126 responses from Oregon State University students. Individuals, on average, correctly answered only 54.10% of the statements based on...
Hypoproteinemia secondary to gastrointestinal disease in horses has traditionally been treated with the administration of colloids such as equine plasma or hetastarch. While plasma transfusion is common, evidence-based guidelines for its use in hypoproteinemic horses are lacking. This study involved prospective and retrospective components that aimed to weigh the efficacy...
As one of database types, CSV type database is widely used by many people because the type serves various useful purposes for business, engineering, and environment. However, the CSV type database could be complicated to understand because it is usually written on spreadsheet like Microsoft Excel format. Therefore, data visualization...
This qualitative study on the experiences of English Speakers of Other Languages (ESOL) educators in the process of reclassifying English Learner Students with Disabilities (ELSWDs) from English Language Development (ELD) services in Oregon sought the answers to two questions: (1) Who is making reclassification decisions? and (2) How are reclassification decisions made on behalf of ELSWDs?...
The proliferation of light emitting diodes (LEDs) are increasing human light exposure, yet the long-term effects of such exposure remains unknown. The current study aims to address this by measuring the longevity of Drosophila melanogaster kept in several light conditions. Initial longevity testing determined that flies kept in daily light-dark...
