Effects Of Intertidal Position On Metabolism And Behavior In The Acorn Barnacle, Balanus Glandula, Kali Horn

Master's Theses

The intertidal zone is characterized by persistent, tidally-driven fluctuations in both abiotic (e.g., temperature, [O₂], salinity) and biotic (e.g., food availability, predation) conditions, which makes this a very physiologically challenging habitat for resident organisms. The magnitude and degree of variability of these environmental stressors differs between intertidal zones, with the most extreme physiological stress often being experienced by organisms in the high intertidal. Given that many of the fluctuating conditions in this environment are primary drivers of metabolic rate (e.g., temperature, [O₂], food availability), we hypothesized that sessile conspecifics residing in different tidal zones would exhibit …

Impact Of Feeding Distillers Grains Or Isolated Components In Distillers' Grains To Growing And Finishing Cattle, And The Comparison Of Protein Content And In-Situ Digestibility Of Feeds Commonly Used In Feedlot Diets, Brianna B. Conroy

Department of Animal Science: Dissertations, Theses, and Student Research

The use of distillers' grains originating from biofuel production has become widely used in feedlot diets. Distillers' grains has been identified as having an increased feeding value relative to dry-rolled corn, in recent years the composition of distillers' grains has begun to change due to greater refinement in the ethanol production process. Two feedlot trials were conducted to evaluate the contribution of fat, fiber, and protein from distillers' grains in the diets of growing and finishing cattle. Growing steers were fed a grass hay-based ration, including a corn control diet compared to a diet containing modified distillers' grains plus solubles, …

The purpose was to understand the role of dual credit STEM courses in rural Nebraska high schools and the impact these courses had on the institution. The interview process revealed the lack of uniformity in dual credit processes throughout the state.

The concept of dual credit is widely discussed. The potential benefits and challenges of these courses and programs are vast. Without national legislation, each state can make determinations and decisions about state-wide policies related …

Pharmacometabolomics Of Respiratory Phenotypic Response To Dexamethasone In Preterm Infants At Risk For Bronchopulmonary Dysplasia., Tamorah R. Lewis Md Phd, Prabhakar Chalise, Cheri Gauldin, William E. Truog

Manuscripts, Articles, Book Chapters and Other Papers

A prospective cohort study was performed in preterm infants less than 32 weeks gestation at birth who were treated with dexamethasone for developing or established bronchopulmonary dysplasia (BPD). Respiratory phenotype (Respiratory Severity Score (RSS)), serum, and urine metabolomics were assessed before and after treatment. Ten infants provided nine matched serum and nine matched urine samples. There was a significant decrease in RSS with steroid treatment. Serum gluconic acid had the largest median fold change (140 times decreased, P = 0.008). In metabolite set enrichment analysis, in both serum and urine, the urea cycle, ammonia recycling, and malate-aspartate shuttle pathways were …

Mitochondrial And Nuclear Multilocus Phylogeny Of Rhipicephalus Ticks From Kenya, Esther G. Kanduma, Richard P. Bishop, Naftaly W. Githaka, Robert A. Skilton, Heloise Heyne, Joram M. Mwacharo

All Peer-Reviewed Publications

The morphological diversity of African ticks of the genus Rhipicephalus and subgenus Boophilus have been studied in detail. However, their taxonomy remains poorly resolved with limited molecular studies performed to improve inter-species discrimination. Herein, ribosomal cytochrome c oxidase I (COI), 12S ribosomal DNA (12S rDNA) and nuclear ribosomal DNA internal transcriber spacer 2 (ITS2) were analyzed in Rhipicephalus tick populations in Kenya. While the morphological and molecular criteria separated R. e. evertsi, R. pulchellus and R. appendiculatus from other members of the genus, except the morphologically similar sibling species R. zambeziensis, this was not the case for other tick populations. …

Pharmacokinetics Of 99mTc-Hmpao In Isolated Perfused Rat Lungs, Anne V. Clough, Katherine Barry, Benjamin Michael Rizzo, Elizabeth R. Jacobs, Said H. Audi

Biomedical Engineering Faculty Research and Publications

Lung uptake of technetium-labeled hexamethylpropyleneamine oxime (HMPAO) increases in rat models of human acute lung injury, consistent with increases in lung tissue glutathione (GSH). Since ^99mTc-HMPAO uptake is the net result of multiple cellular and vascular processes, the objective was to develop an approach to investigate the pharmacokinetics of ^99mTc-HMPAO uptake in isolated perfused rat lungs. Lungs of anesthetized rats were excised and connected to a ventilation-perfusion system. ^99mTc-HMPAO (56 MBq) was injected into the pulmonary arterial cannula, a time sequence of images was acquired, and lung time-activity curves were constructed. Imaging was repeated with a range …

Insuring Nature, Carolyn Kousky, Sarah E. Light

Duke Law Journal

Scholars and policymakers have argued that insurance can shape behavior in ways that mitigate climate risks, such as by providing financial incentives to property owners to safeguard their property from increasingly intense hurricanes or from the risk of sea-level rise. But natural ecosystems like coral reefs, mangroves, and forest ecosystems can themselves protect property from these increased climate risks. This Article turns the climate governance literature on its head, examining the circumstances under which it is possible to insure nature itself in order to preserve these critical ecosystem services in the face of a changing climate.

Student Perceptions Of Trivium-Based Education In Classical Christian Schools: A Phenomenological Study, Robert Todd Mitchell

Doctoral Dissertations and Projects

The purpose of this phenomenological study is to describe the lived experiences of students who graduated from modern classical Christian schools. The theoretical framework utilized is Bandura’s Social Learning Theory (SLT) as it relates to his concept of academic self-efficacy (ASE). Bandura (1986) posited that there are four constructs that serve as predictors in the development of ASE: mastery experiences, vicarious experiences, social persuasion, and physiological response. To address the research problem, I identified a purposive criteria sampling of 8 participants who graduated from accredited and member ACCS schools having experienced all three components of the trivium. Of the eight …

Philip Scranton & Patrick Fridenson's Reimagining Business History, Laura Phillips Sawyer

Scholarly Works

Philip Scranton and Patrick Fridenson—two senior scholars from Rutgers University and École des Hautes Études en Sciences Sociales, Paris, respectively—have brought together their decades of experience as practitioners and editors to explore new directions in research and writing in business history. But this is a different kind of historiographical book. In fact, it is “the inverse of a historiographical analysis”; it seeks to provide a “prospective” “collection of ordered, grouped assertions” (9). It is a “book of perspectives” that “has purposes not an argument” and is intended to be browsed, not read cover to cover. Yet, the authors clearly take …

Strengthening Your Community By Tackling Challenges Together: Lessons From The High Desert Partnership, Jennifer H. Allen, Connie P. Ozawa, Julia Babcock

National Policy Consensus Center Publications

The people of Harney County, Oregon, have a story to tell about healing decades of conflict and coming together to ensure their community survives and thrives. Harney County, located in the southeast corner of the state, is the largest and one of the least populated of Oregon’s counties. It is a place of wide open spaces, with sagebrush deserts, rich wetlands, expansive alkali flats, stark mountains, and stately ponderosa pine forests. The economy relies heavily on the land for farming, ranching, and forestry. Yet the majority of Harney’s land is publicly owned. Historically, that was a recipe for heated disagreements …

Bewitching Power: The Virtuosity Of Gender In Dekker And Massinger's The Virgin Martyr, Thomas Fish

Faculty Articles

This paper considers Thomas Dekker and Philip Massinger’s play The Virgin Martyr (1622) in light of scientific notions of the female body circulating during the period to illustrate how the performance of martyrdom manifested a performance of gender virtuosity, elevating it to the status of the supernatural or divine. Like well-known female martyrs from the period, such as Anne Askew, the protagonist, Dorothea, takes on characteristically male attributes: she assumes the role of the soldier and defies scientific understanding of the female gender by sealing her phlegmatic “leaky” body and exuding divine heat that defies her cold, wet “nature." The …

Overhauling Ocean Spatial Planning To Improve Marine Megafauna Conservation, Ana Micaela Martins Sequeira, Graeme Clive Hays, David Sims, Víctor Eguíluz, Jorge Rodríguez, Michelle Heupel, Rob Harcourt, Hannah Calich, Nuno Queiroz, Daniel Paul Costa, Juan Fernández-Gracia, Luciana Ferreira, Simon David Goldsworthy, Mark Andrew Hindell, Mary-Anne Lea, Mark Meekan, Anthony Michael Pagano, Scott Shaffer, Julia Reisser, Michele Thums, Michael Weise, Carlos Duarte

Faculty Publications, Biological Sciences

Tracking data have led to evidence-based conservation of marine megafauna, but a disconnect remains between the many 1000s of individual animals that have been tracked and the use of these data in conservation and management actions. Furthermore, the focus of most conservation efforts is within Exclusive Economic Zones despite the ability of these species to move 1000s of kilometers across multiple national jurisdictions. To assist the goal of the United Nations General Assembly’s recent effort to negotiate a global treaty to conserve biodiversity on the high seas, we propose the development of a new frontier in dynamic marine spatial management. …

Groundwater Level Mapping Tool: Development Of A Web Application To Effectively Characterize Groundwater Resources, Steven William Evans

Theses and Dissertations

Groundwater is used worldwide as a major source for agricultural irrigation, industrial processes, mining, and drinking water. An accurate understanding of groundwater levels and trends is essential for decision makers to effectively manage groundwater resources throughout an aquifer, ensuring its sustainable development and usage. Unfortunately, groundwater is one of the most challenging and expensive water resources to characterize, quantify, and monitor on a regional basis. Data, though present, are often limited or sporadic, and are generally not used to their full potential to aid decision makers in their groundwater management.This thesis presents a solution to this under-utilization of available data …

An Analysis Of Ground Stone From The Basketmaker Communities Project In Montezuma County, Southwest Colorado, Anna R. Dempsey Alves

Department of Anthropology: Theses and Student Research

In this thesis, I analyze an assemblage of ground stone tools, including manos and metates, from Basketmaker III period (A.D. 500-725) settlements in the central Mesa Verde region of Montezuma County, Colorado. Ground stone is a historically understudied class of artifacts, and the data collection and analysis practices employed for most projects remain subpar, despite the publication of best practices guidelines (Adams 2014). Ground stone informs on critical research topics and must be analyzed to the same degree as other artifact categories. The sites include the Dillard site (5MT10647), an aggregated site with a great kiva, and five surrounding, smaller …

In Vitro Investigation Of The Effect Of Camel Milkproteins And Its Fractions On Insulin Receptor Function, Arshida Ashraf

Biology Theses

Camel milk (CM) has been reported to have anti-diabetic properties in many in vitro and in vivo studies but the molecular basis of such beneficial properties are still elusive. Recently, camel milk whey proteins (CWPs) have been shown to positively affect the activity of the human insulin receptor (hIR) in cell lines. In this study, we profiled crude CWPs and their hydrolysates as well as camel milk lactoferrin (CMLF) for their pharmacological and functional effects on hIR activity and its downstream signaling in both human embryonic kidney (HEK293) and hepatocarcinoma (HepG2) cell lines. For this, bioluminescence resonance energy transfer (BRET) …

Analysis Of Genetic Variation Of Western And Eastern Populations Of Socotra Cormorant (Phalacrocorax Nigrogularis) In The Uae, Salama Rashed Al Mansouri

Biology Theses

Understanding the genetic structure of threatened and endangered species is important in management and conservation efforts. Measuring the pattern and scale of genetic variation within and among populations is important for understanding population dynamics. It helps us improve our understanding of the ecological and genetic relation between the populations. The current research looks at the population structure of the endemic seabird of the United Arab Emirates (UAE), the Socotra cormorant (Phalacrocorax nigrogularis). The lack of genetic information, increased threats, and small breeding habitats of the Socotra cormorants, makes it important to investigate the genetic population structure in the …

Desertification Risk Analysis Based On Soils And Climate In Olive Cultivated Areas In Tulare County, California, Zehra Kavakli Karatas

USF Tampa Graduate Theses and Dissertations

Desertification is one of the most critical environmental problems caused by human activities and climate change. As a result of human activities, land degradation has been seen in many agricultural areas. Intense pressure on cultivated fields causes loss of soil fertility, which can then lead to desertification. Planting plant drought-resistant plants, such as olives, is one strategy for reducing desertification risk in cultivated areas. It is essential to find a way not only how to combat this process but also how to adapt or survive with desertification conditions. Defining desertification risks have a fundamental role in combating drought. The goal …

Estimation Of Infectious Intestinal Disease Burden And Description Of The Infectious Disease Surveillance System In Ras Al Khaimah, United Arab Emirates, Fatema Hamdan Saif Al Alkeem Al Zaabi

Dissertations

Introduction: Infectious disease (ID) is an ongoing problem worldwide. In order to manage this problem, it is important to have an integrated and effective surveillance system that can be used to estimate the burden of ID. There is a scarcity of studies published on the prevalence of IDs in the United Arab Emirates (UAE), both in hospital settings and in the community. Infectious Intestinal Disease (IIDs) have been one of the most commonest IDs that have been studied in the community around the world, there are no studies on the prevalence of IIDs in Ras Al Khaimah (RAK). Furthermore, while …

Taking Age Out Of Play: Children’S Animistic Philosophising Through A Picturebook, Joanna Haynes, Karin Murris

Plymouth Institute of Education

This paper emerges from experiences of putting picturebooks, philosophy with children and posthumanism into play. Responding to Derrida's notion of a ‘return to childhood’, we propose a different move of ‘re-turning to child/ren’, drawing from various entangled sources. First, the figuration of posthuman child (Murris, 2016) disrupts the conception of temporality that takes development and progress as inevitable. The posthuman child expresses the idea of the knowing subject as an unbounded sympoietic system. We put to work Miranda Fricker's notion of epistemic injustice to reanimate thought, with Tim Ingold and Jane Bennett. In respect of children's animistic philosophizing, our writing …

Properly Handling Negative Values In The Calculation Of Binding Constants By Physicochemical Modeling Of Spectroscopic Titration Data, Nathanael P. Kazmierczak, Douglas A. Vander Griend

University Faculty Publications and Creative Works

To implement equilibrium hard-modeling of spectroscopic titration data, the analyst must make a variety of crucial data processing choices that address negative absorbance and molar absorptivity values. The efficacy of three such methodological options is evaluated via high-throughput Monte Carlo simulations, root-mean-square error surface mapping, and two mathematical theorems. Accuracy of the calculated binding constant values constitutes the key figure of merit used to compare different data analysis approaches. First, using singular value decomposition to filter the raw absorbance data prior to modeling often reduces the number of negative values involved but has little effect on the calculated binding constant …

“Smashing Into Crowds” -- An Analysis Of Vehicle Ramming Attacks, Brian Michael Jenkins, Bruce R. Butterworth

Mineta Transportation Institute

Vehicle ramming attacks are not new. But since 2010 Jihadists have urged their use. Is this the wave of the future, or a terrorist fad? To answer this and other questions the authors expanded and updated the database used in their May 2018 MTI Security Perspective entitled An Analysis of Vehicle Ramming as a Terrorist Threat to include 184 attacks since January 1, 1970. They also reviewed literature and examined some cases in detail. This MTI Security perspective indicates that while not new, vehicle rammings are more frequent and lethal since 2014, although the number of attacks seems to be …
