Thermodynamic Limitations To Agricultural Productivity And Food Security: Livestock In Sub-Saharan Africa, Calvin Harman

Department of Agricultural and Biological Systems Engineering: Dissertations, Theses, and Student Research

By 2050, to feed a nearly tripling and more urbanized population in sub-Saharan Africa (SSA) will require significant increases in crop productivity throughout the region’s agricultural systems, if a greater reliance on imports is to be avoided. Increases in crop yields to maximum potential productivity (closure of crop yield gaps) can produce more calories and protein, but may be insufficient to sustain the burgeoning human population according to recent analysis (van Ittersum et al., 2016). In this thesis, alternative management options (i.e. crop allocation and crop substitutions) are found to increase total energy productivity and the thermodynamic efficiency of food …

Cultivation Of Chlorella Sorokiniana Using Beef Feedlot Runoff Holding Pond Effluent, Mitchell Klaus Goedeken

Department of Agricultural and Biological Systems Engineering: Dissertations, Theses, and Student Research

A study was conducted to test the suitability of utilizing beef feedlot runoff holding pond effluent for cultivating algae. The algae strain used, Chlorella sorokiniana, was previously identified as a potential energy feedstock for cattle. The previous research was initiated in pursuit of a goal to develop a cycle of utilizing nutrients from beef manure to cultivate algae and then utilizing dewatered algae as a feed supplement for beef cattle.

Runoff holding pond effluent samples were collected from commercial beef production operations in Nebraska during spring 2016. Equal portions of samples from each cooperating farm were composited and then aliquoted …

Assessing Relationships Between Angling Effort And Larval Trematodes In Small Bluegill, Alexis Park

School of Natural Resources: Dissertations, Theses, and Student Research

I wanted to determine if catch-and-release angling increased larval trematodes in small (50-160 mm) bluegill (Lepomis macrochirus). I used angling effort as a proxy for amount of catch-and-release angling. I assumed bluegill assessed, due to their size and age, experienced catch-and-release events. I assessed larval trematode intensity, black spot (Crassiphiala bulboglossa), and white grub (Posthodiplostomum minimum centrarchi), in 750 bluegill. The first objective was to quantify the association between angling effort and reservoir area. Angling effort and reservoir area were positively correlated. The second objective was to determine if angling effort, reservoir area, bluegill …

Effects Of Vagotomy And Fenugreek On Hyperlipidemia And Insulin Resistance, Rituraj Khound

Department of Nutrition and Health Sciences: Dissertations, Theses, and Student Research

Hyperlipidemia is the impairment of lipid metabolism marked by abnormally high levels of lipid in circulation. This has been implicated in a number of metabolic diseases including diabetes, cardiovascular diseases, and nonalcoholic fatty liver disease. Insulin resistance is the impairment of insulin action, which leads to several diseases such as obesity and type 2 diabetes. New clinical and therapeutic approaches are warranted for the prevention and treatment of hyperlipidemia and insulin resistance. In our study, we investigated the mechanism underlying the effect of complete disruption of the sub-diaphragmatic vagus nerve (vagotomy) on hyperlipidemia and insulin sensitivity. We observed that vagotomy …

The Problem Of Illusion In The Phenomenology Of Claude Romano, Joseph Cutolo

Student Theses and Dissertations

The phenomenology of Claude Romano constructs a strict distinction between perceptions and illusions. This distinction is so strict that the former excludes the latter completely. Putting this distinction into play is not a local decision about our experiences and the structures of our experiences. This decision brings with it metaphysical, ontological, and phenomenological frameworks to ground it. In what follows I attempt to draw out the consequences of Romano’s decisions about our experience, and to study the philosophical frameworks that underlie his decisions. In doing so, I reconnect his phenomenology with a wider terminology of phenomenology, in order to study …

Diversification Of The Japanese Judiciary, Daniel H. Foote

Washington International Law Journal

Japan has a career judiciary. The Courts Act of 1947 provides that judges may be appointed from among prosecutors, attorneys, and law professors. In practice, however, the vast majority of judges come from a fourth category, “assistant judges,” who are appointed directly upon completion of the legal training program and typically serve through retirement. This continues a career tradition that dates back to the late nineteenth century. For nearly that long, the Japanese bar has been advocating that the career system should be abolished and that a substantial portion of the judiciary, if not all judges, should be drawn from …

Control Surfaces Of Aquatic Vertebrates: Active And Passive Design And Function, Frank E. Fish, George V. Lauder

Biology Faculty Publications

Aquatic vertebrates display a variety of control surfaces that are used for propulsion, stabilization, trim and maneuvering. Control surfaces include paired and median fins in fishes, and flippers and flukes in secondarily aquatic tetrapods. These structures initially evolved from embryonic fin folds in fishes and have been modified into complex control surfaces in derived aquatic tetrapods. Control surfaces function both actively and passively to produce torque about the center of mass by the generation of either lift or drag, or both, and thus produce vector forces to effect rectilinear locomotion, trim control and maneuvers. In addition to fins and flippers, …

Virtual Reality Based Simulation Testbed For Evaluation Of Autonomous Vehicle Behavior Algorithms, Vibhor Rastogi

All Theses

Validation of Autonomous Vehicle behavior algorithms requires thorough testing against a wide range of test scenarios. It is not financially and practically feasible to conduct these tests entirely in a real world setting. We discuss the design and implementation of a VR based simulation testbed that allows such testing to be conducted virtually, linking a computer-generated environment to the system running the autonomous vehicle's decision making algorithms and operating in real-time. We illustrate the system by further discussing the design and implementation of an application that builds upon the VR simulation testbed to visually evaluate the performance of an Advance …

An Evaluation Of Methodologies For Measuring Antibacterial Activity Of The Epithelial Mucosa Of Farmed Tilapia (Oreochromis Niloticus) Against Streptococcus Agalactiae And Streptococcus Iniae, Betsy Virginia White Presgraves

All Theses

Tilapiine cichlids are the third largest farmed fish worldwide and are among the easiest and most profitable fish to farm. The most common pathogens affecting farmed tilapia are Streptococcus agalactiae and Streptococcus iniae, which together account for losses of more than 150 million dollars annually. Fish are at the highest risk for developing a Streptococcus infection when they are in high density stock conditions. Research indicates that the secondary effects of high stock density such as low dissolved oxygen and high ammonia levels are of less significance to infection and mortality than the damage that over stocking causes to …

Effects Of Dialogic Reading In A Special Day Class, Donna Senn

Dissertations, Masters Theses, Capstones, and Culminating Projects

Early Childhood Special Education provides services to children aged three to five years. A predominant identifier is very low communication skills (Shevell, et al, 2003; Kaiser & Roberts, 2011; Robertson & Ohi, 2016). Dialogic Reading techniques have demonstrated successes in various settings (Hargrave & Senechal, 2000; Whitehurst et al., 1988; Trivette & Dunst, 2009). The rationale for this study was grounded in Rogoff’s, “apprenticeship in thinking” (1990, p. 7) theory. The research literature reviewed centered on three primary lines of inquiry namely, 1) The social aspect of language learning; 2) Speech and language interventions; and 3) Dialogic reading strategies. This …

Assessment And Attitudes: Biodiversity In Urban Landscapes Of North Central Texas, Gray Harrison Kerry A.

Landscape Architecture Masters & Design Theses - Archive

North Central Texas is expected to undergo increased population growth and density inside and outside of current municipal boundaries. As development increases to meet the needs of the growing population, the landscape is transformed, which results in the loss or homogenization of species (McKinney, 2006; Vitousek, Mooney, Lubchenco, & Melillo, 1997). This study examined how landscape architects can quickly assess biodiversity on a project site before and after construction without specialized knowledge or skills. Three methods were used to collect data for this study: interviews, a DNA assessment of soil fungi, and a rapid biological assessment (BioBlitz). Two groups were …

Assessing The Predictability Of Highway Safety Manual Crash Prediction Models In The State Of South Carolina, Mahdi Rajabi

All Dissertations

Crash frequency has been identified by many experts as one of the most important safety measures, and the Highway Safety Manual (HSM) encompasses the most commonly accepted predictive models to predict the crash frequency for specific road segments and intersections. The HSM recommends that the models should be calibrated using data from a jurisdiction where the models will be applied. Large amounts of data collection and data analysis are required for this purpose, which presents numerous challenges. The HSM further recommends that, in case of available data and expertise, local agencies may develop jurisdiction-specific models. In this dissertation, the process …

Island Biogeography Of Small Mammals And Associated Ectoparasites In The Ozark Glades, Emily M. Beasley

Graduate Theses/Dissertations

Island Biogeography Theory (IBT) explains and quantifies broad-scale ecological patterns among islands and isolated habitat patches. IBT predicts that the number of species per habitat patch varies as a function of area and isolation as a result of local colonization and extinction. IBT has been extended to habitat islands and hosts as islands for their associated parasites. In the latter system, host body mass acts as a substitute for island area, whereas host population density is used as a measure of isolation. Using the fragmented Ozark glades and the small mammals therein as a model system, I 1) used a …

Assessment Of Reliability And Stability Of Various Visual Search Parameters, Michael Don Mizer

Graduate Theses/Dissertations

Research in social science has been on a continuous self-correcting path as scientists find new ways to look at old problems. Recent technology has given us the ability to perform compounded calculations in a fraction of previous times while recording complex measurements with greater degrees of precision. While this is helpful regarding corporeal measures, quantifying cognition is still a difficult task. Recently, many computer-aided eye tracking devices have been developed and used to validate visual search theories. However, few inquiries have been made assessing the reliability and stability of these methods. This study assessed the reliability and stability of visual …

Ecology Of Hatchling Alligator Snapping Turtles (Macrochelys Temminckii), Sarah J. Spangler

Graduate Theses/Dissertations

Little is known about the first year of life for many of the world’s freshwater turtles. This is due in part to their cryptic nature and the difficulty of locating hatchlings in the wild. The lack of information about this demographically important age group has led researchers to draw conclusions from indirect inferences about survival rates and ecological roles of hatchlings that may or may not be accurate. To begin filling in some of these gaps, I focused on the first year in an alligator snapping turtle’s life. I studied: (1) circadian and circannual patterns of activity, (2) growth rates …

High Performance Computing Techniques For Analyzing Risky Decision Making, Vinay B. Gavirangaswamy

Dissertations

The process or activity of making choices when subject to gain or loss can be understood as risky decision making (RDM). Risky Decisions consists of outcomes of decisions that may probabilistically result in unfavorable results. Every organism that lives faces this challenge and recent research suggests that there is a computational process involved in making these decisions. This has led to new approaches in the study of RDM. My dissertation is towards contributing to expand on the existing knowledge of RDM processes.

The core contribution of my work is an analysis and development of high performance computing techniques that improves …

A Deep Learníng-Based Data Minimization Algorithm For Big Genomics Data In Support Of Lot And Secure Smart Health Services, Mohammed Aledhari

Dissertations

In the age of Big Genomics Data, institutes such as the National Human Genome Research Institute (NHGRI),1000-Genomes project, and the international cancer sequencing consortium are faced with the challenge of sharing large volumes of data between internationallydispersed sample collectors, data analyzers, and researchers, a process that up until now has been plagued by unreliable transfers and slow connection speeds. These occur due to the inherent throughput bottlenecks of traditional transfer technologies. One suggested solution is using the cloud as an infrastructure to solve the store and analysis challenges. However, the transfer and share of the genomics datasets between biological laboratories …

A Spiritual Framework Of Organic Oneness: The Eco-Theological Shift Towards A Collective Ecological Consciousness, Kjirsten Francisco José Durand

Electronic Theses and Dissertations 2020 - Present

Earth’s environment has been undergoing unprecedented rates of degradation during the Anthropocene paradigm. Current projections for the near future show climate change producing grim outcomes for most habitable parts of the world. This thesis defends the argument that in order to adequately address the state of the environment, humanity must experience a shift in collective consciousness away from the current philosophical paradigm, and instead adopt a paradigm that enables a common mindset regarding the place of humans within the natural environment. Various forms of spiritual ecology are explored: deep ecology, biblical eco-theology, and eco-feminist theology. These positions are explored in …

Kdoqi Us Commentary On The 2017 Kdigo Clinical Practice Guideline Update For The Diagnosis, Evaluation, Prevention, And Treatment Of Chronic Kidney Disease-Mineral And Bone Disorder (Ckd-Mbd), Tamara Isakova, Thomas L. Nickolas, Michelle Denburg, Sri Yarlagadda, Daniel E. Weiner, Orlando M. Gutiérrez, Vinod Bansal, Sylvia E. Rosas, Sagar Nigwekar, Jerry Yee, Holly Kramer

Nephrology Articles

Chronic kidney disease-mineral and bone disorder (CKD-MBD) encompasses laboratory and bone abnormalities and vascular calcification and has deleterious effects on clinical outcomes. KDOQI (Kidney Disease Outcomes Quality Initiative), an initiative of the National Kidney Foundation, addressed this issue with the publication of a clinical practice guideline for bone metabolism and disease in CKD in 2003, and 2 years later, a new definition and classification scheme for CKD-MBD was developed following a KDIGO (Kidney Disease: Improving Global Outcomes) Controversies Conference. The initial KDIGO guideline on CKD-MBD was then published in 2009. New evidence was subsequently reviewed at the 2013 KDIGO Controversies …

The Eleanor Mann School of Nursing Undergraduate Honors Theses

This research project investigates how university students are affected by interacting with therapy horses. Stress is the factor that will be evaluated in this particular study. The self-rated stress scores will be acquired from University of Arkansas students both before and after interacting with specially trained therapy horses during an Equine Assisted Activity and Therapy (EAAT) class offered at the University. Stress will be evaluated by students taking a survey inquiring about daily stressors including finances, school, work and relationships. The data collected will be compared by pre- and post- interactions with the horses. We expect that the pre- and …

Acyl-Homoserine Lactone Based Modulators For Rhli, A Quorum Sensing Signal Synthase In Pseudomonas Aeruginosa, Daniel D. Shin

Boise State University Theses and Dissertations

Gram-negative bacteria use N-acyl-homoserine lactone (AHL) autoinducer based signal system, known as quorum sensing (QS), to modulate the gene expression for such traits as biofilm formation, toxin production, and antibiotic resistance. Therefore, there is great potential in pursuing quorum sensing inhibition (QSI) as a means of achieving antivirulence. Pseudomonas aeruginosa, an opportunistic pathogen commonly found in healthcare-related infections, use two LuxI/R type systems to regulate AHL-based quorum sensing: LasI/R and RhlI/R. LasI (initiator protein/signal synthase) and LasR (receptor) use 3-oxododecanoyl-L-homoserine lactone signal molecule while RhlI and RhlR use butanoyl-L-homoserine lactone autoinducer. Thus far, most of the studies have …

A Pilot Study Of Computerized, Tailored Intervention To Promote Hpv Vaccination In Mexican-Heritage Adolescents, Angela Chia-Chen Chen, Michael Todd, Ashish Amresh, Usha Menon, Laura Szalacha

Publications

This study examined feasibility, acceptability, and preliminary effects of a computer-tailored intervention aimed at promoting HPV vaccination in Mexican-heritage adolescents aged 11-17. Among 46 Mexican-heritage parents who had one or more eligible children who had not received HPV vaccines, 91% (n = 42) completed the intervention and assessments via touchscreen tablet computers in a vaccine clinic. Mean knowledge scores increased significantly from pre- to post-intervention. After the intervention, 95% (n = 40) of parents intended to get their children vaccinated; 50% (n=21) of them consented to vaccination immediately, resulting in 24 adolescents being vaccinated at that time. All parents reported …

Evidence For Aposematic Coloration Of The Sea Urchin Astropyga Pulvinata, December 2017, Nathan Howell

Monteverde Institute: Tropical Ecology and Conservation

Astropyga pulvinata is a brightly colored urchin found in some tropical pacific waters including the coast of Costa Rica. The aim of this study was to test a possible explanation for the coloration of A. pulvinata. I tested the hypothesis that the coloration of A. pulvinata is aposematic. I tested this by poking A. pulvinata and another species of urchin, the uniformly black Diadema mexicanum, then comparing their reactions. The results indicated that A. pulvinata were more likely to move as a response to the poking stimulus than D. mexicanum, which was contrary to the predicted hypothesis. 100% of A. …

Species Abundance Of Fungi Is Greater In Landslide Areas Compared To Undisturbed Areas Of The Forest In Monteverde, Puntarenas, Costa Rica, December 2017, Sunshine Lopez

Monteverde Institute: Tropical Ecology and Conservation

Fungi plays an important role in the ecosystem by decomposing dead plants, and other organic matter. Without this process, there would be an accumulation of organic material in the forest which would go un-decomposed. Fungi which are saprotrophic macrofungi from the phyla Basidioycota and Ascomycota have the vital job of recycling nutrients from dead plant material in the forest back into the soil. The abundance of organic material created by the landslides on the reserve behind Estación Biológica in Monteverde, Puntarenas, Costa Rica may have given rise to nearly twice the amount of different species of fungi (n=31) compared to …

Zooplankton Morphospecies And Abundance In Relation With Tide In Mangroves Of Cuajiniquil, Costa Rica, December 2017, Stephanie Li

Monteverde Institute: Tropical Ecology and Conservation

In two decades, at least 35% of the world’s mangroves have been lost, which is more than both tropical rain forests and coral reefs (Valiela et al. 2001). Mangroves act as an important habitat and feeding grounds for fish (Sasekumar et al. 1992). Zooplankton are abundant in the mangroves and are important organisms to study to get an understanding of the foundation of ecosystem’s food chain. Zooplankton eat phytoplankton and get eaten by small fish and other sea animals, providing a food source and extending the food chain. I aimed to ask and answer the following question: is there a …
