Cost-Benefit Analysis Of Composting At The University Of Kentucky, Jennifer Sutton Jan 2020

Cost-Benefit Analysis Of Composting At The University Of Kentucky, Jennifer Sutton

MPA/MPP/MPFM Capstone Projects

This study is a cost-benefit analysis (CBA) of the University of Kentucky’s composting program. Food waste is collected from two major dining facilities on campus and composted at the university’s C. Oran Little Research Center in Woodford County. This CBA only considers the direct accounting costs of the program. Three models were developed and analyzed. Ultimately, all three models resulted in a deficit over the life of the project. However, it is important to note that benefits were likely understated because this CBA did not take into consideration the environmental or social benefits that exist from a composting program at …

Open Ensemble Modeling Of Confined Electrolytes, Serban Zamfir Jan 2020

Open Ensemble Modeling Of Confined Electrolytes, Serban Zamfir

Theses and Dissertations

The main purpose of my study was to work towards better understanding the behavior of salt solutions in nanoconfinements and its causes. To this end I have developed an in-house C++ code that can perform notoriously challenging open ensemble Monte Carlo molecular simulations, calculate relevant thermodynamic and extract structural information about each system. I use this code in my first project which deals with the intrusion/extrusion of aqueous NaCl into a nanopore open to a pressurized bulk environment. For my second project, I study the effect of explicitly accounting for intramolecular polarization and accompanying multi-body interactions on the uptake, structure, …

Molecular Typing Of Rickettsia Akari, Marina E. Eremeeva Jan 2020

Molecular Typing Of Rickettsia Akari, Marina E. Eremeeva

Biostatistics, Epidemiology & Environmental Health Sciences: Faculty Publications

Rickettsia akari is an obligate intracellular bacterium that causes smallpox rickettsia. Rickettsia akari is an atypical member of the rickettsia spotted fever (SFG) group because it circulates in gamasid mites; however, only limited data are available regarding the degree of genetic diversity of R. akari isolates. We examined 13 isolates of R. akari isolated from humans, rodents, and ticks in the United States, the countries of the former USSR, and the former Yugoslavia for the period from 1946 to 2003 for diversity in the composition of tandem repeats (TR) and intergenic regions (IGR). Using the Tandem Repeat Finder software (http://tandem.bu.edu) …

Toward Efficient Automation Of Interpretable Machine Learning Boosting, Nathan Neuhaus Jan 2020

Toward Efficient Automation Of Interpretable Machine Learning Boosting, Nathan Neuhaus

All Master's Theses

Developing efficient automated methods for Interpretable Machine Learning (IML) is an important and long-term goal in the field of Artificial Intelligence. Currently the Machine Learning landscape is dominated by Neural Networks (NNs) and Support Vector Machines (SVMs), models which are often highly accurate. Despite high accuracy, such models are essentially “black boxes” and therefore are too risky for situations like healthcare where real lives are at stake. In such situations, so called “glass-box” models, such as Decision Trees (DTs), Bayesian Networks (BNs), and Logic Relational (LR) models are often preferred, however can succumb to accuracy limitations. Unfortunately, having to choose …

Image Features For Tuberculosis Classification In Digital Chest Radiographs, Brian Hooper Jan 2020

Image Features For Tuberculosis Classification In Digital Chest Radiographs, Brian Hooper

All Master's Theses

Tuberculosis (TB) is a respiratory disease which affects millions of people each year, accounting for the tenth leading cause of death worldwide, and is especially prevalent in underdeveloped regions where access to adequate medical care may be limited. Analysis of digital chest radiographs (CXRs) is a common and inexpensive method for the diagnosis of TB; however, a trained radiologist is required to interpret the results, and is subject to human error. Computer-Aided Detection (CAD) systems are a promising machine-learning based solution to automate the diagnosis of TB from CXR images. As the dimensionality of a high-resolution CXR image is very …

Image Forgery Detection With Machine Learning, Lubna Alzamil Jan 2020

Image Forgery Detection With Machine Learning, Lubna Alzamil

All Master's Theses

The issue of forged images is currently a global issue that spreads mainly via social networks. Image forgery has weakened Internet users’ confidence in digital images. In recent years, extensive research has been devoted to the development of new techniques to combat various image forgery attacks. Detecting fake images prevents counterfeit photos from being used to deceive or cause harm to others. In this thesis, we propose methods using the error level analysis algorithm to detect manipulated images. We show that our combination of image pre-processing and machine learning techniques is an efficient approach to detecting image forgery attacks.

Sampling The Local Fare: Fishes At The Sam Israel House Pit (45gr76), Soap Lake, Washington, Adam Fruge Jan 2020

Sampling The Local Fare: Fishes At The Sam Israel House Pit (45gr76), Soap Lake, Washington, Adam Fruge

All Master's Theses

The Sam Israel site is a precontact archaeological complex with numerous fish bones at the north end of Soap Lake, Washington. Excavated in 1976, the fish remains recovered from there were never fully analyzed prior to this research. Since this inland Columbia Plateau site had thousands of fish bones, it contained untapped potential for our understanding of ancient local fish procurement. As such, I conducted a detailed analysis of 2,862 fish bone specimens from the Sam Israel House Pit locus to: study a larger sample of fish bones in greater detail than was done before; compare the distribution of fishes …

Documenting The Earthquake History Of The Thousand Springs Fault In Summer Lake Basin, Oregon, Usa, Elizabeth Curtiss Jan 2020

Documenting The Earthquake History Of The Thousand Springs Fault In Summer Lake Basin, Oregon, Usa, Elizabeth Curtiss

All Master's Theses

Defining seismic hazards in low-strain-rate regions such as the northwestern Basin and Range can be difficult due to the infrequency of earthquakes. Revealing the earthquake records of low-strain-rate regions can refine our understanding of the variability of earthquake sizes and recurrence intervals, however, which can ultimately improve hazard analysis. Four active normal faults form the Summer Lake basin, in the northwestern Basin and Range: The Thousand Springs (TSF), Ana River (ARF), Slide Mountain, and Winter Ridge faults. Other than the TSF, the faults in the Summer Lake basin have documented histories that include surface-rupturing (>M6) earthquakes. Scarps along the …

Toadal Isolation: Genetic Connectivity Of The Western Toad (Anaxyrus Boreas) Along I-90 In The Snoqualmie Pass Area Of Washington State, Anneliese Myers

All Master's Theses

Single-nucleotide polymorphisms (SNPs) were used to assess the genetic connectivity of western toad (Anaxyrus boreas) breeding populations along Interstate-90 near Snoqualmie Pass, WA. Sites north and south of the freeway were sampled during the breeding season of 2019. SNP loci were subsequently generated using the proprietary DArTseqTM (Canberra, ACT, Australia) method. A total of 15,468 SNPs were used to calculate pairwise FST values and three distinct breeding populations were identified, two north and one south of I-90. All pairwise FST values between these sites were low (0.02) but significantly different from 0. The lowest pairwise …

A Geochemical Assessment Of Potential Groundwater Storage Locations Within The Yakima River Basin, Silas Sleeper Jan 2020

A Geochemical Assessment Of Potential Groundwater Storage Locations Within The Yakima River Basin, Silas Sleeper

All Master's Theses

Currently in the Yakima River Basin more people possess surface water rights than there is available surface water. As a result, the local community devised the Yakima River Basin Integrated Water Management Plan, with the goal of creating a sustainable source of water for the foreseeable future. One of seven elements outlined in this plan is groundwater storage. The idea is to take available water during high spring flows and store it in the subsurface. The water will then be used to increase stream flows and decrease stream water temperatures during the summer months. A main challenge associated with groundwater …

Modeling Cle Elum Reservoir Shoreline Erosion: Gis Analysis To Support Cultural And Environmental Resource Management, Yakima Basin, Washington, Michael H. Horner Jan 2020

Modeling Cle Elum Reservoir Shoreline Erosion: Gis Analysis To Support Cultural And Environmental Resource Management, Yakima Basin, Washington, Michael H. Horner

All Master's Theses

In the Yakima Basin, managers are expanding reservoirs including Cle Elum Lake to increase the availability of water. The objective of this study was to examine areas prone to further shoreline erosion to inform resource management. This research included the use of airphotos and fieldwork to identify erosional shorelines. Erosion was verified in the field using a video survey as well as indicators such as shoreline slope, sediment size, and nearshore width. Near-term erosional segments were identified by more rapidly receding bluffs while long-term erosional segments included both bedrock cliffs and bluffs. Although most of the shoreline is depositional, near-term …

Mapping And Modeling The Seattle Fault Tsunami Inundation In Puget Sound, David Bruce Jan 2020

Mapping And Modeling The Seattle Fault Tsunami Inundation In Puget Sound, David Bruce

All Master's Theses

Coastal communities of Puget Sound are susceptible to tsunami inundation from multiple sources. Two sources of potential tsunami hazard that threaten the region are earthquakes on crustal faults in the Puget Lowlands, or earthquakes originating on the Cascadia subduction zone. This study investigated two coastal marshes in Puget Sound, Deer Lagoon and Doe-Kag-Wats, for evidence of a paleotsunami record to combine with tsunami modeling, in order to predict how future events could inundate Puget Sound. A deposit, interpreted as a paleotsunami, is traceable thought the marsh stratigraphy near the modern day tidal inlet of Deer Lagoon, a site that has …

Applying Garnet And Zircon Ree Linkages To Determine Timing Of P-T Conditions And Tectonic Implications For Uhp Eclogites And Hp Granulites, Dulan Uhp Terrane, China, Wesley Weisberg Jan 2020

Applying Garnet And Zircon Ree Linkages To Determine Timing Of P-T Conditions And Tectonic Implications For Uhp Eclogites And Hp Granulites, Dulan Uhp Terrane, China, Wesley Weisberg

All Master's Theses

The Dulan ultrahigh-pressure (UHP) terrane in western China hosts rocks that record continental collision, however; the timing of peak P-T conditions in UHP eclogites and HP granulites, and the tectonic significance of their spatial relationship within the Dulan UHP terrane are not well understood. This study, (1) evaluates rare earth element (REE) equilibrium between garnet and zircon, to assess coeval growth; (2) links timing (from zircon) to the P-T history (from garnet) to constrain the P-T-t path of the Dulan UHP terrane and interpret implications for zircon growth; (3) refines P-T conditions for HP granulite; and (4) evaluates the tectonic …

Me, Myself, And I: The Impact Of Metacognitive Strategies On Student Locus Of Control And Critical Thinking Skills, Danielle Kuchler

All Master's Theses

We live in an era when a college degree is essentially required for entry into good-paying careers, and yet achievement of a college degree is unacceptably low. Only 60% of students who enroll go on to graduate from 4-year colleges and universities in 6 years or fewer (National Center for Higher Education 2018). Why is this happening? What are the long-term intellectual and economic implications of ill-prepared students? We must ask ourselves if students are really prepared with the knowledge, skills, and dispositions to be successful in college and whether those attributes are developed while in college. Two of the …

Recovering Lost Information From Avocational Projectile Point Collections, Mackenzie Hughes Jan 2020

Recovering Lost Information From Avocational Projectile Point Collections, Mackenzie Hughes

All Master's Theses

Human prehistory in North America has sparked the interest of private citizens for decades, sometimes leading to an accumulation of avocational artifact collections that lack site-level provenience. The Wild/Clymer artifacts (n = 1,371) are one such collection where precise site provenience was lost. The analysis aims to recover regional provenience by using morphology, raw material sourcing, and typology to create a data set. The avocational collection data set was analyzed by comparing it to the professionally recorded archaeological data sets from within 100 miles of Frenchglen, Oregon. A paradigmatic classification approach identified 606 typeable points in the avocational collection, in …

Distribution Of Invasive Plant Species On Debris Cones At Mount Rainier National Park, Shaun Morrison Jan 2020

Distribution Of Invasive Plant Species On Debris Cones At Mount Rainier National Park, Shaun Morrison

All Master's Theses

Invasive plant populations within Mount Rainier National Park are a biological and ecological threat to the unique mountain landscape. A better understanding of their distribution and transport within the landscape is needed to improve invasive species monitoring for National Park Service management. This study investigates how invasive plant populations in Stevens Canyon are utilizing the debris cone disturbances and associated geomorphic processes to facilitate movement within the park. Vegetation transects were performed along Stevens Canyon Road (to observe the roadside community composition) and on the debris cone features (to observe species movement from the roadside). These vegetation observations are presented …

Modeling Of Potential Historical Tsunamis From Large Earthquakes In The Izu-Bonin Mariana Subduction Zone, Rachelle Reisinger Jan 2020

Modeling Of Potential Historical Tsunamis From Large Earthquakes In The Izu-Bonin Mariana Subduction Zone, Rachelle Reisinger

All Master's Theses

The Izu-Bonin Mariana (IBM) subduction zone is an over 3000-km long oceanic-oceanic convergence zone with no instrumental record of great subduction-zone earthquakes (Mw > 8.0). Due to the lack of great earthquakes and the oceanic-oceanic subduction style, previous researchers have speculated that the IBM does not produce great earthquakes. The same behavior was also proposed for the northern Japan and Cascadia subduction zones, which has since been proven false. We use the tsunami model GeoClaw (v5.6.0) with adjoint-guided refinement level flagging to simulate IBM earthquakes in three separate segments to produce estimates of wave heights at locations around the Pacific …

The Role Of Cumulate Plagioclase Entrainment In The Steens Basalt, Se Oregon: Insights From The Magma Chamber Simulator, Valerie Strasser Jan 2020

The Role Of Cumulate Plagioclase Entrainment In The Steens Basalt, Se Oregon: Insights From The Magma Chamber Simulator, Valerie Strasser

All Master's Theses

The Steens Basalt, located in SE Oregon, is the oldest and most mafic member of the Columbia River Basalt Group (CRBG). Because the Steens Basalt contains large (up to 6 cm) and abundant (up to 40%) plagioclase crystals, it is classified as a Giant Plagioclase basalt (GPB). Understanding the origin of these giant plagioclase yields insight into magmatic processes like recharge, crustal assimilation, cumulate entrainment, and fractional crystallization. Because large and abundant plagioclase are found in other flood basalt provinces worldwide, these results could also enhance understanding of magma evolution and storage conditions for GPB worldwide. The Steens basalt is …

Late Holocene Paleoflood Hydrology Of The Snake River In The Lower Hells Canyon, Idaho, Kent C. Allen Jan 2020

Late Holocene Paleoflood Hydrology Of The Snake River In The Lower Hells Canyon, Idaho, Kent C. Allen

All Master's Theses

The Snake River watershed spans a large geographic region from the Rocky Mountains to the inland Pacific Northwest, and a comprehensive paleoflood chronology on the mainstem of the river is key to identifying the frequency and magnitude of large prehistoric floods within the region. We examined and compared four sites of slackwater deposits along a 20-km reach of the Lower Hells Canyon on the Snake River, Idaho. The sites contain evidence of up to 34 paleofloods within the last 1700 years. Stratigraphic breaks, soils, and in-situ plant or archaeological materials demarcate distinct layers that represent discrete paleoflood events. Radiocarbon dates …

Selective Synthesis Of Trans-Fused Lactam-Lactones By Vicinal Difunctionalization Of Readily Affordable Allylic Lactams, Morgan J. Rodriguez Jan 2020

Selective Synthesis Of Trans-Fused Lactam-Lactones By Vicinal Difunctionalization Of Readily Affordable Allylic Lactams, Morgan J. Rodriguez

All Master's Theses

With intrinsic versatility and an overwhelming presence in natural products, nitrogen- and oxygen-containing heterocycles boast a plethora of medicinal properties. Specifically, lactams and lactones are the respective luminaries of the antibiotic and flavor worlds. However, the synthesis of fused lactams-lactones, especially those bearing trans-fusion, is challenging from the standpoints of chemoselectivity, stereoselectivity, and regioselectivity. In this thesis, the highly-selective, cost-effective, and high-yielding conversion of readily affordable allylic lactams into trans-fused lactam-lactones by intramolecular vicinal difunctionalization is explored. The approach is highly divergent and requires only two steps, which bodes well for the construction of medicinally pertinent fragments. It …

The Utilization Of Sex Hormone Antibodies For Screening And Separation Of Trace Biological Mixtures, Kristin N. Jones Jan 2020

The Utilization Of Sex Hormone Antibodies For Screening And Separation Of Trace Biological Mixtures, Kristin N. Jones

Master of Science in Forensic Science Directed Research Projects

Touch or trace evidence consists of epidermal cells deposited by contact with items such as handled objects, touched surfaces, or worn clothes. This type of evidence has surpassed most other sample types submitted to forensic labs and typically consists of low quantities of DNA and multiple contributors. In this study epithelial skin cells, i.e., “touch/trace evidence,” were used as they are estimated to constitute approximately half of the casework evidence items submitted for DNA analysis. For the optimization of antibody staining, male and female skin epithelial samples from donors were incubated and hybridized with antibodies of various concentrations of Alexa …

Microseismic Evidence For Bookshelf Faulting In Western Montana, Ellen Mcgough Smith Jan 2020

Microseismic Evidence For Bookshelf Faulting In Western Montana, Ellen Mcgough Smith

Graduate Student Theses, Dissertations, & Professional Papers

One of the most seismically active regions in the western United States, far from any major plate boundary, is the Intermountain Seismic Belt (ISB). On 6 July 2017, a M5.8 earthquake occurred 11 km southeast of Lincoln, Montana within the ISB. This was the largest earthquake to occur in the state of Montana since the 1959 M7.3 Hebgen Lake earthquake. Data from the University of Montana Seismic Network (UMSN), the Montana Regional Seismic Network (MRSN), and the United States Geological Survey (USGS) were used to investigate the aftershock sequences following the M5.8 Lincoln event.
