  • Examination of Dielectric Properties of BaTiO3-SrTiO3 Based Systems

    Creator:
    Trobough, Nathaniel D.
    Abstract:
    This thesis examines the dielectric properties of two systems based on the perovskite materials barium titanate and strontium titanate. A solid solution was created starting with these base materials and then adding varying amounts of bismuth-zinc titanate and sodium niobate. These compositions were calcined and sintered at temperatures determined to...

  • CO₂ capture from wet flue gas using a water-stable and cost-effective metal-organic framework

    Creator:
    Loughran, Ryan P.
    Abstract:
    We report the use of MIL-120 as a water-stable and cost-effective metal-organic framework (MOF) for selectively capturing CO₂ from wet flue gas. Synthesized using inexpensive and environmentally benign reagents in water, MIL-120 possesses one-dimensional pores decorated with hydroxyl-bridged Al(III) ions and benzene rings with an interstitial spacing of 4.78 Å....

  • Effect of acupuncture on somatic cell count, milk ion conductivity, and milk serum enzyme concentrations in dairy cattle with subclinical mastitis

    Creator:
    Ryan, Elise L.
    Abstract:
    The objective of this research was to determine if acupuncture can reduce bovine mammary inflammation. Lactating cows at the Oregon State University Dairy Research Center were selected based on Dairy Herd Improvement Association reports indicating a SCC >500,000 cells/mL. A California Mastitis Test (CMT) score of greater than one was...

  • Breeding Snap Beans for Organic Agriculture: Genomic Shifts under Different Agricultural Management Systems

    Creator:
    King, Ryan M.
    Abstract:
    Although the concept of breeding crops for organic agricultural systems has been around for decades, few studies have been reported for vegetable crops to quantify and compare how conventional and organic systems differ in their selection pressures on genotypes advancing through the breeding cycle; especially research utilizing modern sequencing capabilities....

  • Cancer Cell Detection with Mask R-CNN

    Creator:
    Wong, Ryan
    Abstract:
    Instance segmentation, the classification and localization of objects in an image, is a problem in cellular biophysics due to the physiological relevance of cell morphology. Particularly, cancer cells migrate in tissue space by changing their body shape similarly to how humans extend their limbs to swim through water. Monitoring such...

    McMinds, Ryan C.
    Abstract:
    The modern world has presented many threats to the health and stability of ecosystems worldwide. One of the most biodiverse ecosystems, coral reefs, faces particularly strong pressures, and is already declining rapidly in complexity and area. Although the stressors that affect reefs are diverse, ranging from nutrient pollution to overfishing,...

  • Evaluating the Efficiency, Capabilities, and Scalability of a LoRaWAN Network in a Fenceless Grazing Implementation

    Creator:
    Alder, Ryan
    Abstract:
    LoRaWAN networks are becoming more popular, and it is becoming common for developers to look at solutions utilizing Internet of Things concepts. In this paper, I introduce a Fenceless Grazing System utilizing the LoRaWAN network stack and discuss the limitations of this theorized network to better understand the scalability prior...

  • Effective Signage to Manage Recreation at OSU’s Research Forests

    Creator:
    Walters, Corinne A.
    Abstract:
    This thesis focuses on creating effective signage for the Oregon State University College of Forestry Research Forests (OSU Research Forests). The OSU Research Forests are a unique setting because they offer space for research, class field trips, active timber harvest, and public recreation. The public interface requires the management at...

  • Genome Size, Ploidy, and Base Composition of Wild and Cultivated Acer

    Creator:
    Contreras, Ryan N. and Shearer, Kimberly
    Abstract:
    Acer is a large and important genus of woody plants most commonly encountered as small to large trees in urban landscapes. Considerable investigation has been devoted to addressing the taxonomy of maples, but little is known about genome sizes across the genus. Relatively more work has been conducted to determine...

  • The Cosmetic Stay-Green Trait in Snap Bean and the Event Cascade that Reduces Seed Germination and Emergence

    Creator:
    Cirak, Melike
    Abstract:
    The persistent color (pc) trait in snap bean (Phaseolus vulgaris L.) belongs to a member of the cosmetic stay-green gene family. It is considered very desirable by snap bean breeders for its impacts on pod quality. Persistent color imparts a uniform dark-green color to pods and expresses in seeds as...
