Assessing The Influence Of Behavioural Parameterisation On The Dispersal Of Larvae In Marine Systems, M. K. James, J. A. Polton, C. G. Mayorga-Adame, K. L. Howell, A. M. Knights

School of Biological and Marine Sciences

Predicting dispersal and quantifying ecological connectivity are increasingly referenced as fundamental to understanding how biodiversity is structured across space and time. Dispersal models can provide insight, but their predictions are influenced by our capacity to simulate the biology and physics known to influence dispersal. In a marine context, vertical swimming behaviour is considered important in influencing the spatial organisation of species across seascapes, but the mechanisms underpinning these movements remain unresolved, making it unclear how best to incorporate behaviour within models. Here, using a 3-D hydrodynamic model coupled with a Lagrangian particle tracker, we show how different modelled larval behaviours, …

Three-Component Composite Phase-Change Material For Thermal Regulation, Bidisha Ojha

McKelvey School of Engineering Graduate Student Theses & Dissertations

Phase change materials can increase the efficiency of many energy-intensive applications, such as solar power plants, solar heating and cooling systems, heat recovery systems, photovoltaic electricity systems, and Earth satellite systems. In several proposed thermal management systems for high power electronic equipment, PCMs change phase and absorb latent heat at peak energy loads during operation, then dissipate this energy later to prevent overheating. More specifically, composite PCM’s, consisting of an organic material (e.g., paraffin) and an inorganic material (e.g., metallic alloys or salt hydrates), provide a superior balance of thermal conductivity and latent heat for thermal management. Organic PCMs have …

Dissecting The Recruitment And Self-Organization Of Αsma-Positive Fibroblasts In The Foreign Body Response, Maria Parlani, Matthew L Bedell, Antonios G Mikos, Peter Friedl, Eleonora Dondossola

Faculty, Staff and Student Publications

The foreign body response (FBR) is a clinically relevant issue that can cause malfunction of implanted medical devices by fibrotic encapsulation. Whereas inflammatory aspects of the FBR have been established, underlying fibroblast-dependent mechanisms remain unclear. We here combine multiphoton microscopy with ad hoc reporter mice expressing α-smooth muscle actin (αSMA) protein to determine the locoregional fibroblast dynamics, activation, and fibrotic encapsulation of polymeric materials. Fibroblasts invaded as individual cells and established a multicellular network, which transited to a two-compartment fibrotic response displaying an αSMA cold external capsule and a long-lasting, inner αSMA hot environment. The recruitment of fibroblasts and extent …

Crossing The Grebbe Line: Canada’S Faustian Bargain To Save Civilians In The Western Netherlands, April-May 1945, Nathan Dyck

Canadian Military History

Beginning at the military-political level and ending at the regimental level, this paper will explore the growth of Canadian responsibility within a failing Allied relief framework throughout the Dutch Hunger Winter 1944-1945. Beginning in early April 1945, I Canadian Corps experienced a growing responsibility to secure an independently negotiated and effective ceasefire on the Grebbe Line to enable transport of food prior to broader German surrender. Under the name of Operation Faust, I Corps utilised targeted medical and food relief practices to address gaps in Allied relief capacity, following what Canadian Military Headquarters (CMHQ) referred to as a “hastily improvised” …

Pursuit To Valenciennes 1918: The Fate Of Soldiers At The Point Of Capture, Brian Pascas

Canadian Military History

This article tracks the Canadian Corps’ pursuit of the retreating German army in the last weeks of the First World War. As French hamlets, villages and towns were liberated, the war-weary troops—nursing grudges after almost four years of war—encountered civilians who had endured poor and sometimes brutal treatment under the yoke of the cruel invader. During the Battle of Valenciennes hundreds of German soldiers were killed; the vast majority perished under immense artillery barrages. But a number who survived the onslaught of shells and bullets succumbed to Canadians’ rifles while or after surrendering. Motives are identified that drove frontline soldiers …

Doctoral Studies As Learning To Rename The World, Hyleen Mariaye

Journal of Multicultural Affairs

The reflective experience documented in this paper engages with doctoral learning from Freire’s (1968/2000) conceptual lens of naming the world. Written from the narrative lens of the supervisor, it considers how doctoral level studies in education can position both the supervisor and the candidates as agents actively reconstructing their understanding of the world and their place in it. The doctoral journey is viewed as praxis compelling researchers to expand their frames for reading the world, accommodating the other, including multiple voices and thus demonstrating commitment to a global and yet constantly contested notion of citizenship.

Invasions Of Dicamba Particles: Holding States Accountable For Taking Offsite Property Owners' Right To Exclude, Terence J. Centner

University of Cincinnati Law Review

In 2017, special formulations of dicamba herbicides known as over-the-top products were marketed for post-emergent use on genetically engineered soybeans and cotton. The use of these products was accompanied by considerable herbicide drift and volatilization that harmed millions of acres of nearby crops. In 2018, the EPA added requirements to the products’ labels to preclude offsite injuries. However, for each growing season during 2018-2021, unacceptable offsite injuries were reported in the major soybean and cotton producing states. Because they received reported injuries, state agencies issuing new registrations for dicamba products in 2018 and 2020 knew offsite spray drift and volatilization …

Mechanical and Materials Engineering Faculty Publications

Introduction: Direct quantification of hemodynamic factors applied to a cerebral aneurysm (CA) remains inaccessible due to the lack of technologies to measure the flow field within an aneurysm precisely. This study aimed to develop an in vitro validated 3D in silico patient-specific internal carotid artery sidewall aneurysm (ICASA) model which can be used to investigate hemodynamic factors on the CA pathophysiology. Methods: The validated ICASA model was developed by quantifying and comparing the flow field using particle image velocimetry (PIV) measurements and computational fluid dynamics (CFD) simulations. Specifically, the flow field characteristics, i.e., blood flowrates, normalized velocity profiles, flow streamlines, …

Highly Power Dense Dc To Three-Phase Ac Modular Converters With Tiny Module Capacitors, Wiwin Hartini Lew

Dissertations and Theses

A Modular Multilevel Converter (MMC) is an attractive candidate in high power conversion due to its modularity and scalability. The energy storage element, namely the module capacitance in the MMC submodule circuit, is typically large and when scaled to convert high power, requires very bulky module capacitors. In addition to deteriorating the power density, the design necessitates the use of electrolytic capacitors, which further affects the overall converter efficiency and reliability. This research presents an MMC submodule topology and the accompanying modulation approach that reduces the submodule capacitance requirements significantly compared to conventional MMC topology (few micro-farads versus several milli-farads). …

Surface Modification Of 3d Printed Microfluidic Devices For Controlled Wetting In Two-Phase Flow, Chandler A. Warr, Nicole G. Crawford, Gregory P. Nordin, William G. Pitt

Faculty Publications

Microfluidic devices (MFDs) printed in 3-D geometry using digital light projection to polymerize monomers often have surfaces that are not as hydrophobic as MFDs made from polydimethylsiloxane. Droplet microfluidics in these types of devices are subject to droplet adhesion and aqueous spreading on less hydrophobic MFD surfaces. We have developed a post-processing technique using hydrophobic monomers that renders the surfaces of these devices much more hydrophobic. The technique is fast and easy, and involves flowing monomer without initiator into the channels and then exposing the entire device to UV light that generates radicals from the initiator molecules remaining in the …

Efficient Crispr/Hdr-Mediated Knock-In System And Method Of Use, Jia-Wang Wang, Richard F. Lockey

USF Patents

The clustered regularly interspaced short palindromic repeat (CRISPR) gene editing technique, based on the non-homologous end-joining (NHEJ) repair pathway, can efficiently generate gene knockouts of variably sizes. More precise genome editing, either the insertion or deletion of a desired fragment, can be done by combining the homology-directed-repair (HDR) pathway with CRISPR cleavage. HDR-mediated gene knock-in experiments are inefficient, with no reports of successful gene knock-in with DNA fragments larger than 4 kb. Targeted insertion of large DNA fragments (7.4 and 5.8 kb) into the genomes of mouse embryonic stem cells and zygotes, respectively, using the CRISPR/HDR technique without NHEJ inhibitors …

The Influence Of Spatialheterogeneity On Ocean Quahog (Arctica Islandica) Population Dynamics Along The Mid-Atlantic Bight, Jillian Sower

Master's Theses

The ocean quahog (Arctica islandica) support an economically important fishery in the US, though little is known about their life history traits. To determine how these traits vary geographically, the age frequencies and growth rates from two New Jersey sites (NJ1 & NJ2) as well as Georges Bank (GB) and Long Island (LI) were analyzed. Though sexual dimorphism in bivalves is rare, recent research has shown that A. islandica display distinct differences in sizes between males and females, with females reaching larger sizes than those of males. To determine when this difference in size occurs, the growth rates …
