The Presence Of Mercury (Hg) And Perfluoroalkyl Substances (Pfas) In The Guana And Tolomato Rivers, Morgan E. Lattomus

UNF Graduate Theses and Dissertations

The Guana and Tolomato Rivers provide essential habitat for several ecologically and economically important species and is a well-loved and recreated area. Spanning the northeastern Florida coast, the rivers are home to over 50 endangered or threatened species and host several habitat restoration projects due to their ecological significance and proximity to development along the coast. The effects of human influence and pollution, and specifically toxic metal mercury (Hg) and perfluoroalkyl substances (PFAS), are not well known within the system. Hg is known to biomagnify within food webs, and there is a considerable lack of literature concerning PFAS behavior within …

Pygoscelis Penguins Prefer Different Oceanographic And Terrestrial Habitats During The Austral Summer, Katherine L. Gallagher, Rachel Herman, Katherine Walton, Michael S. Dinniman, Heather J. Lynch

OES Faculty Publications

Pygoscelis penguins interact with both terrestrial and marine environments, especially during the austral summer when they raise their chicks. Accessible ice-free ground spaces serve as locations for penguins to build colonies and successfully raise chicks while the surrounding marine environment serves as the foraging grounds for adult birds. Penguins must be able to navigate through the waters around their colonies to forage for Antarctic krill (Euphausia superba), their primary prey during the austral summer. Krill, whose distributions are driven partially by the surrounding physics and partially by their behaviors, must also be plentiful in the waters near the …

Heterospecific Coprophagy In The White-Tailed Deer Odocoileus Virginianus (Zimmermann, 1780) In Costa Rica, Mora Manuel Jose, Juan De Dios Astorga-Acuña

Biology Faculty Publications and Presentations

Animals may engage in coprophagy, including heterospecific coprophagy, where they consume the feces of other species. The white-tailed deer, Odocoileus virginianus, primarily feeds on plant material, such as tender forbs and shrub shoots. This report documents a case of heterospecific coprophagy by the white-tailed deer in Costa Rica, where two individuals were observed consuming domestic horse feces. The reasons for heterospecific coprophagy in ruminants like the white-tailed deer are unclear. Nutritional supplementation, microbial transfer, or other ecological factors may play a role in this behavior. However, such a behavior also poses risks, including the transmission of diseases and parasites from …

Erk1/2 Inhibition Alleviates Diabetic Cardiomyopathy By Suppressing Fatty Acid Metabolism, Erin Mclean, Caroline De Roo, Annabel Maag, Megan Coble, Jefferson Cano, Ruijie Liu

Open Access Publishing Support Funded Articles

Background: Diabetes mellitus is associated with morphological and functional impairment of the heart primarily due to lipid toxicity caused by increased fatty acid metabolism. Extracellular signal-regulated protein kinases 1 and 2 (ERK1/2) have been implicated in the metabolism of fatty acids in the liver and skeletal muscles. However, their role in the heart in diabetes remains unclear. In this study, we tested our hypothesis that pharmacological inhibition of ERK1/2 alleviates cardiac remodeling in diabetic mice through a reduction in fatty acid metabolism.   Methods: ERK1/2 phosphorylation in diabetes was determined both in vitro and in vivo.

The Organization Of Serotonergic Fibers In The Pacific Angelshark Brain: Neuroanatomical And Supercomputing Analyses, Skirmantas Janušonis, Ralf Metzler, Thomas Vojta

Physics Faculty Research & Creative Works

Serotonergic axons (fibers) are a universal feature of all vertebrate brains. They form meshworks, typically quantified with regional density measurements, and appear to support neuroplasticity. The self-organization of this system remains poorly understood, partly because of the strong stochasticity of individual fiber trajectories. In an extension to our previous analyses of the mouse brain, serotonergic fibers were investigated in the brain of the Pacific angel shark (Squatina californica), a representative of a unique (ray-like) lineage of the squalomorph sharks. First, the fundamental cytoarchitecture of the angel shark brain was examined, including the expression of ionized calcium-binding adapter molecule 1 (Iba1, …

The Ever-Present Nature Of Christ In The Title Of Jehovah, Dan Belnap

Faculty Publications

In January 2000 the First Presidency and the Quorum of the Twelve Apostles of The Church of Jesus Christ of Latter-day Saints bore testimony to the world of the reality, humanity, and divinity of Jesus Christ in a document titled “The Living Christ: The Testimony of the Apostles.” Among its many truths was the following: “He [Christ] was the Great Jehovah of the Old Testament.”1 Though this was not the first time Church leadership had declared Christ to be Jehovah, the pronouncement does reemphasize this teaching. It also emphasizes the centrality of Christ in the Old Testament. In fact, the …

Understanding The Influence Of Image Enhancement On Underwater Object Detection: A Quantitative And Qualitative Study, Ashraf Saleem, Ali Awad, Sidike Paheding, Evan Lucas, Timothy C. Havens, Peter C. Esselman

Michigan Tech Publications

Underwater image enhancement is often perceived as a disadvantageous process to object detection. We propose a novel analysis of the interactions between enhancement and detection, elaborating on the potential of enhancement to improve detection. In particular, we evaluate object detection performance for each individual image rather than across the entire set to allow a direct performance comparison of each image before and after enhancement. This approach enables the generation of unique queries to identify the outperforming and underperforming enhanced images compared to the original images. To accomplish this, we first produce enhanced image sets of the original images using recent …

A Transferable Approach For Quantifying Benthic Fish Sizes And Densities In Annotated Underwater Images, Peter C. Esselman, Shadi Moradi, Joseph K. Geisz, Christopher Roussi

Michigan Tech Publications

Benthic fishes are a common target of scientific monitoring but are difficult to quantify because of their close association to bottom habitats that are hard to access. Advances in image-acquisition technologies, machine vision and deep learning have made capturing and quantifying fishes with cameras increasingly feasible. We present a method and open-source software called ‘FishScale’ to estimate benthic fish lengths, numeric abundance and biomass density in underwater environments assessed with down-looking monocular images. ‘FishScale’ estimates fish abundances and size frequencies from near-nadir monocular images where fish have already been semantically segmented. The software accounts for lens distortion, underwater magnification effects …

Now I See: Video Supports For English Language Learners, Joanna C. Zimmerle, Hanrui He, Tara Hill

Journal of English Learner Education

General education teachers are often unprepared by teacher preparation programs and limited professional development opportunities to support English Language Learners (ELLs), despite the increasing number of ELLs entering US schools and the trend towards placing them in mainstream classrooms. Video resources offer one viable approach to supporting the language learning of ELLs, drawing upon theoretical frameworks such as dual-coding, constructivist theory, and sociocultural perspectives. This paper describes the use of video resources to assist general education teachers in effectively leveraging videos to support the language learning of ELLs in mainstream classrooms.

New Reader Response: An Examination Of Three High-Achieving High School Readers And Their Literacies, Minkyu Kim

Essays in Education

Since its inception, reader response theory has battled misrepresentations. It was reduced to discursive anarchy, perceived as not rigorous, and set apart from important scholarship movements like critical theory. This research argues that by expanding the definition of “reader” in “reader response” to include digital (aka “new”) literacies, the reader-text transaction can be much more inclusive, dynamic, and most importantly, true to our students’ everyday literacies. This article also includes a discussion of why it is so important for teachers to include digital platforms as sites of interrogation in a safe educative setting. By studying the out-of-school literacy behaviors of …

The last comprehensive report on injuries related to noncanine bites and stings seen in emergency departments (EDs) across the US was between 2011 and 2015.

Methods

We performed a retrospective analysis from 2014-2019 on marine injuries from a large hospital network with over 180 hospitals, 100 freestanding EDs, and 170 urgent care centers to provide an update on the volume and …

Enhancing Image Classification Using A Convolutional Neural Network Model, Zena M. Saadi, Ahmed T. Sadiq, Omar Z. Akif, Marwa M. Eid

Journal of Soft Computing and Computer Applications

In recent years, with the rapid development of the current classification system in digital content identification, automatic classification of images has become the most challenging task in the field of computer vision. As can be seen, vision is quite challenging for a system to automatically understand and analyze images, as compared to the vision of humans. Some research papers have been done to address the issue in the low-level current classification system, but the output was restricted only to basic image features. However, similarly, the approaches fail to accurately classify images. For the results expected in this field, such as …

Crowd-Sourced Learning For Computer Graphics Applications, Yunhao Zhang

Dissertations

Computer Graphics (CG) revolves around virtual content creation using computational methods, spanning applications from games to visual effects. Typically, the creation of CG content is led by expert practitioners who guide computational algorithms towards satisfactory results. Thus, creating CG content often requires manual iterations encompassing algorithm design, parameter tuning, and aesthetic feedback. This work investigates how to leverage crowd-sourcing to streamline such creation processes, focusing on animation and simulation. In animation, a novel crowd-sourcing framework is proposed for combat animation, enabling users to analyze motion similarities, and retrieve matching motions using novel crowd-sourced motion features. Such features enable quantifying previously …

New Chronology For Neolithic Cultures In The Lake Eyasi Basin, Northern Tanzania, Musa Said Mwitondi, Pastory Magayane Bushozi

Zamani: A Journal of African Historical Studies

There have been several studies on Neolithic Cultures in the Serengeti National. The recovered archaeological materials include domestic and wild fauna remains, potsherds and lithic artefacts, ochre, and stone enclosures, dating between 7200 and 4900 BP. In the East African Rift System (EARS), conventional ages for Neolithic Cultures are inferred from the most extensively researched Neolithic sites in Kenya, where the oldest Nderit ware, cattle and caprine in the Lake Turkana Basin, northern Kenya, date ca. 5200 BP. Studies on the Neolithic of EARS have been structured to fit into the migration or diffusion models that consider the spread of …

Smallpox Outbreaks And Immunization Policies In Tanzania From The Late Nineteenth Century To The First World War, Lorne Larson

Zamani: A Journal of African Historical Studies

An estimated 300 million people died globally from smallpox in the 20th century alone. There was very much a North/South divide in the existence of the disease in that period, with countries across South America, Africa and Asia recording the majority of cases. In 1966 the World Health Organization launched an intensive effort to finally eliminate the disease. The last known endemic case of smallpox was reported in Somalia in 1977, and that outbreak was promptly contained. In 1980 smallpox was declared eradicated – the only infectious disease affecting humans to achieve this distinction. This remains among the most notable …

Revisiting African Religion As An Academic Discipline In Africa: History And Prospects, Ivan B. Kivinge

Zamani: A Journal of African Historical Studies

Three main religious traditions—indigenous African beliefs and practices (African religion), Christianity and Islam—have dominated everyday life of communities in Africa today. Scholarship on religion indicates that only African religion originated in Africa— Christianity and Islam are foreign religions. Many Africans today have been active Christians and Muslims, who are sometimes being misleadingly taught that African religion is demonic and forms of paganism. This article employs historical and philosophical approaches to show how the study of African religion has navigated through various historical currents and resultant implications on the way the current generation views it. In the end, the article proposes …
