Hydrodynamic Impacts Of Expanding Aquaculture, Zhilong Liu

Electronic Theses and Dissertations

Climate change may potentially change aquatic systems and bring certain risks for aquaculture development. Understanding interactions between aquaculture and the environment helps to ensure aquaculture expansion is sustainable in the future. It is critical to determine how farms influence tidal flow patterns, turbulence, mixing and material transport in estuaries. This research aims to determine the flow response of an oyster farm, predict how expanding farms and farm placement will alter estuarine dynamics, and understand how the design of a farm influences material transport.

The hydrodynamic response of a floating oyster aquaculture farm in a low inflow estuary (the Damariscotta River …

A Theoretical Study Of Synchronous Proton Transfer In (Hf)N, (H2O) N, And (Hcl) N Where N = 3, 4, 5, Johnny Yang

Honors Theses

For (HF)_n, (H₂O)_n, and (HCl)_n (n = 3 − 5), we have rigorously characterized the structures for the minima and transition states for synchronous proton transfer (SPT) with the CCSD(T) method and aug-cc-pVTZ basis set. The electronic barrier heights (∆E^†) associated with these transition states have also been computed with the explicitly correlated CCSD(T)-F12 method and the aug-cc-pVQZ-F12 basis set (abbreviated aQZ-F12). (HCl)_n (n = 3 − 5) SPT transition states have not been previously identified to the best of our knowledge, and they have been found …

Big Data Quality Framework: A Holistic Approach To Continuous Quality Management, Ikbal Taleb, Mohamed Adel Serhani, Chafik Bouhaddioui, Rachida Dssouli

All Works

Big Data is an essential research area for governments, institutions, and private agencies to support their analytics decisions. Big Data refers to all about data, how it is collected, processed, and analyzed to generate value-added data-driven insights and decisions. Degradation in Data Quality may result in unpredictable consequences. In this case, confidence and worthiness in the data and its source are lost. In the Big Data context, data characteristics, such as volume, multi-heterogeneous data sources, and fast data generation, increase the risk of quality degradation and require efficient mechanisms to check data worthiness. However, ensuring Big Data Quality (BDQ) is …

Local Zeta Functions And Koba–Nielsen String Amplitudes, Miriam Bocardo-Gaspar, Hugo García-Compeán, Edgar Y. López, Wilson A. Zúñiga-Galindo

School of Mathematical and Statistical Sciences Faculty Publications and Presentations

This article is a survey of our recent work on the connections between Koba–Nielsen amplitudes and local zeta functions (in the sense of Gel’fand, Weil, Igusa, Sato, Bernstein, Denef, Loeser, etc.). Our research program is motivated by the fact that the p-adic strings seem to be related in some interesting ways with ordinary strings. p-Adic string amplitudes share desired characteristics with their Archimedean counterparts, such as crossing symmetry and invariance under Möbius transformations. A direct connection between p-adic amplitudes and the Archimedean ones is through the limit p→1. Gerasimov and Shatashvili studied the limit p→1 of the p-adic effective action …

Microaggressions In The Academy: One Black Professor’S Narrative, Kevin L. Jones

Journal of Multicultural Affairs

For many Black men in academia, predominantly White institutions are the epicenter of racism and hindered success. My first year as an instructor at a predominantly White institution proved to be an experience I will never forget. I had some expectations of what I would encounter, but what actually happened far exceeded anything I could have imagined. Through the lens of a racial microaggressions framework, my personal narrative describes my lived experiences as a Black male preparing for the academy at a predominantly White institution in the south. Consequently, these experiences had a long-term emotional, physiological, and psychological impact. These …

Déjà Vu Or The Repetitive Nature Of Microaggressions: An Account Of Two Life Changing Experiences, 10 Years Apart, Nina M. Ellis-Hervey

Journal of Multicultural Affairs

According to American Psychologist Angela Lee Duckworth (2016), grit is often described as passion and perseverance for very long-term goals, while encompassing courage, conscientiousness, perseverance, resilience, and passion. Embodying such characteristics has supported me in thriving in various conditions and situations as an African American girl, then a woman. Grit further assisted in me overcoming many obstacles while remaining resilient, open-minded, and inquisitive. At various points in my education, more specifically my time in undergraduate and graduate schooling, and further in my pursuit of tenure as a young professor, I was met with overt and covert exposures to microaggressions of …

Hard Work Through Heart Work: Life Lessons Learned Through My Lens Of Microaggressions, Sean E. Harness

Journal of Multicultural Affairs

According to a study by Johnson-Ahorlu’s (2013), African American students experienced racial stereotypes, which were presented to them as attacks on their academic capabilities. Many of the “attacks” included shock from faculty and peers when they achieved in the classroom and inquiries about their abilities to handle the course workload. I began my life as one of the statistics we read about. More specifically, the “poor Black kid” in inner-city Detroit Michigan who aspired to live a much better life. Although I grew up with very limited financial resources, my support system taught me to remain confident in the face …

Located in Iron County, Utah, the Parowan Gap dinosaur track site contains over one hundred natural casts of non-avian dinosaur tracks preserved in sandstones and siltstones of the Late Cretaceous (≈83 Ma) Iron Springs Formation. For this study, the authors returned to the area to survey for and describe previously unidentified tracks. Many tracks from this new study occur as in situ casts found on the basal surfaces of sandstones deposited by braided and meandering rivers on the coastal plain of the Western Interior Seaway, with some specimens from fallen talus blocks. Over the course of two years, the research …

Effects Of Amino Acid Side-Chain Length And Chemical Structure On Anionic Polyglutamic And Polyaspartic Acid Cellulose-Based Polyelectrolyte Brushes., Dmitry Tolmachev, George Mamistvalov, Natalia Lukasheva, Sergey Larin, Mikko Karttunen

Chemistry Publications

We used atomistic molecular dynamics (MD) simulations to study polyelectrolyte brushes based on anionic α,L-glutamic acid and α,L-aspartic acid grafted on cellulose in the presence of divalent CaCl₂ salt at different concentrations. The motivation is to search for ways to control properties such as sorption capacity and the structural response of the brush to multivalent salts. For this detailed understanding of the role of side-chain length, the chemical structure and their interplay are required. It was found that in the case of glutamic acid oligomers, the longer side chains facilitate attractive interactions with the cellulose surface, which forces the …

Structural Dynamics Of Membrane Interacting Viral Proteins, Nisha Bhattarai

FIU Electronic Theses and Dissertations

Viruses do not possess complete cellular machinery but have the ability to reproduce by utilizing cellular machinery inside host cells. They are nanoscale machines that rapidly modify (evolve) their molecular components to cause disease and death. Therefore, emergence of deadly infectious viruses is a monumental health concern and understanding how viruses are able to enter, replicate, assemble and egress from the host cell is important to mitigate the threat.

A fully active, infectious viral structure is known as a virion. A virion contains genetic material and is enclosed by a capsid. The capsid is a protein shell and some viruses …

Coupled Deep-Mantle Carbon-Water Cycle: Evidence From Lower-Mantle Diamonds, Wenzhong Wang, Oliver Tschauner, Shichun Huang, Zhongqing Wu, Yufei Meng, Hans Bechtel, Ho Kwang Mao

Geoscience Faculty Research

Diamonds form in a variety of environments between subducted crust, lithospheric and deep mantle. Recently, deep source diamonds with inclusions of the high-pressure H O-phase ice-VII were discovered. By correlating the pressures of ice-VII inclusions with those of other high-pressure inclusions, we assess quantitatively the pressures and temperatures of their entrapment. We show that the ice-VII-bearing diamonds formed at depths down to 800 ± 60 km but at temperatures 200–500 K below average mantle temperature that match the pressure-temperature conditions of decomposing dense hydrous mantle silicates. Our work presents strong evidence for coupled recycling of water and carbon in the …

This study quantifies the transmission potential of SARS-CoV-2 across public health districts in Georgia, USA, and tests if per capita cumulative case count varies across counties. To estimate the time-varying reproduction number, Rt of SARS-CoV-2 in Georgia and its 18 public health districts, we apply the R package ‘EpiEstim’ to the time series of historical daily incidence of confirmed cases, 2 March–15 December 2020. The epidemic curve is shifted backward by nine days to account for the incubation period and delay to testing. Linear regression is performed between log10-transformed per capita cumulative case count and log10-transformed population size. We observe …

Using Gis To Create Hazard Maps And Assess Evacuation Routes Around “The Gate To Hell”; Masaya Volcano, Nicaragua, Rebecca Hedges, Stevie Mcdermaid, Jason Kaiser, David Maxwell, Kathy Matthews

The Compass: Earth Science Journal of Sigma Gamma Epsilon

Volcán Masaya in Nicaragua is made of a series of calderas and craters that lies 7 km from the city of Masaya with a population of over 100,000. Masaya is part of the Central American Volcanic Arc (CAVA) which contains hundreds of volcanoes. While many of the volcanoes of the arc produce small, quiescent eruptions, some are capable of large explosive events. The recent cycle of volcanism at Masaya began 7000 years ago. Initial eruptions were primarily lava, small ash flows, ashfalls, and degassing events which eventually gave way to climactic Vulcanian eruptions. The hazards presented from this system affect …

Resolving A One-Year Ecesis Interval For Alaska Paper Birch: Dating A Rockfall Event, Wishbone Hill, Southcentral Alaska, Riley E. Whitney, Alexander K. Stewart, Trent D. Hubbard, Anabella S. Kowalski, Oscar A. Wilkerson

The Compass: Earth Science Journal of Sigma Gamma Epsilon

Numerous large boulders at the base of Wishbone Hill, northeast of Anchorage, Alaska, suggest a historic rockfall event and potential for future surface instability, putting lives and property at risk. The source of the rockfall-boulders is an exposed syncline with a cliff face composed of conglomerate. The age of trees growing atop boulders provides a minimum exposure-age of those boulders and, thus, the rockfall event. To determine when the rockfall occurred, we dated trees growing atop the boulders using tree-ring samples collected from 30 Alaska paper birch trees. After mounting and polishing, each tree-ring sample was dot-counted, and tree-ring widths …

Atmospheric Blocking Drives Recent Albedo Change Across The Western Greenland Ice Sheet Percolation Zone, Hans Peter Marshall, Tate Meehan

Geosciences Faculty Publications and Presentations

Greenland Ice Sheet (GrIS) albedo has decreased over recent decades, contributing to enhanced surface melt and mass loss. However, it remains unclear whether GrIS darkening is due to snow grain size increases, higher concentrations of light-absorbing impurities (LAIs), or a combination. Here, we assess albedo controls in the western GrIS percolation zone using in situ albedo, LAI, and grain size measurements. We find a significant correlation between albedo and snow grain size (p < 0.01), but not with LAIs. Modeling corroborates that LAI concentrations are too low to significantly reduce albedo, but larger grain sizes could reduce albedo by at least ∼3%. Strong atmospheric blocking increases grain sizes and reduces albedo through increased surface temperature, fewer storms, and higher incoming shortwave radiation. These findings clarify the mechanisms by which anomalously strong blocking contributed to recent GrIS albedo decline and mass loss, highlighting the importance of improving projections of future blocking.

Travel Time Patterns Of Students With Special Needs To Special Education Integrated Program-Based Schools In Johor Bahru, Malaysia: An Initial Finding, Nurul Hawani Idris, Nur Afiqah Ahmad Bakhtiar, Mohamad Hafis Izran Ishak

International Journal of Geospatial and Environmental Research

Education for all has been a global priority to ensure that all students have equal access to high-quality education regardless of disability or minority status. In Malaysia, the special education integrated programme (SEIP) is designed to close the inequality gap by integrating special education into existing government and vernacular schools. Numerous studies examine the travel patterns of regular students to school, resulting in a dearth of research on the travel patterns of special needs students to formal school. Thus, this paper uses spatial analysis to demonstrate the travel patterns of students with special needs to SEIP schools. This paper demonstrated …

Multiple myeloma (MM), a clonal plasma cell disorder, disrupts the bones' hematopoiesis and microenvironment homeostasis and ability to mediate an immune response against malignant clones. Despite prominent survival improvement with newer treatment modalities since the 2000s, MM is still considered a non-curable disease. Patients experience disease recurrence episodes with clonal evolution, and with each relapse disease comes back with a more aggressive phenotype. Bruton's Tyrosine Kinase (BTK) has been a major target for B cell clonal disorders and its role in clonal plasma cell disorders is under active investigation. BTK is a cytosolic kinase which plays a major role in …
