Exploring The Deformation Mechanics Of Coal Ribs Using The Distinct Element Modeling Approach, Maurice Sunkpal, Taghi Sherizadeh

Mining Engineering Faculty Research & Creative Works

Understanding coal rib geomechanics is essential for improving rib stability and eliminating fatality and injury trends due to rib failures. There are presently no standardized rib control practices available in most countries. In light of this observed dearth, this investigation aims to improve understanding of rib failure mechanisms using the distinct element modeling (DEM) technique. DEM is chosen because of its superior advantage to explicitly represent discontinuities and their constitutive behaviors, besides that of the intact rock matrix. To analyze the rib stability, a numerical monitoring protocol is implemented to monitor the deformation characteristics of the coal rock mass as …

The Effects Of Counterfactual Thinking On Everyday Meaning, Wynn Tan

Dissertations and Theses Collection (Open Access)

Meaning-making literature largely focuses on predictors of global meaning rather than situational meaning. This is insufficient as both levels of meaning are necessary for a sustained sense of meaning. Past studies found evidence that downward counterfactuals can enhance the meaningfulness of events. However, those findings may be due to existing studies’ focus on major events and did not study how meaning could change over time. For everyday events, upward counterfactuals were proposed to be more apt in enhancing meaning. Using a multiphase diary study, this paper examined whether upward counterfactual thinking predicted event meaningfulness, and more specifically if it was …

Essays On International Trade, Shenxi Song

Dissertations and Theses Collection (Open Access)

Reciprocity is a key principle governing the negotiations under the GATT/WTO agreement, which calls for a balance of concessions among the WTO members. In recent years, however, various politicians across the world have voiced concerns about their country's excessive obligations under the WTO and a lack of reciprocation by their trading partners. The objective in the first chapter is to evaluate the degree to which the pattern of applied tariffs across WTO members deviates from a balanced-concession condition. To this end, we employ a quantitative trade model and use alternative definitions of reciprocity (based on market access or welfare) to …

Redeveloping Homeless History And Chronicity Documentation: A Study For Heartland Family Service, Rachel Riede

Theses/Capstones/Creative Projects

In recent months, the Permanent Supportive Housing (PSH) program at Heartland Family Service (HFS) has seen substantial delays during their intake process, specifically when it comes to verifying a client’s HUD-required homeless history. This has led to an increase in program vacancies, fewer clients served, and an underutilization of the program’s budget, which could also induce more permanent defunding in the future. While the agency is working to address this problem by retraining all of their case managers on how to collect homeless histories, this project seeks to instead identify and address the problem through the case managers’ perspective. Through …

Structure Of Number Theoretic Graphs, Lee Trent

Mathematical Sciences Technical Reports (MSTR)

The tools of graph theory can be used to investigate the structure
imposed on the integers by various relations. Here we investigate two
kinds of graphs. The first, a square product graph, takes for its vertices
the integers 1 through n, and draws edges between numbers whose product
is a square. The second, a square product graph, has the same vertex set,
and draws edges between numbers whose sum is a square.
We investigate the structure of these graphs. For square product
graphs, we provide a rather complete characterization of their structure as
a union of disjoint complete graphs. For …

Amphiphilic Cyclic Cell-Penetrating Peptides Containing Tryptophan And Arginine As Anticancer Agents And Drug Delivery System, Khalid Zoghebi

Pharmaceutical Sciences (PhD) Dissertations

Amphiphilic cyclic cell-penetrating peptides composed of an increasing number of alternative tryptophan (W) and arginine (R) were synthesized and evaluated as a molecular transporter and for their ability to deliver doxorubicin (Dox) and large molecular weight molecules, such as siRNA and proteins. We prepared a cyclic peptide containing alternative tryptophan (W) and arginine (R) residues and a lysine containing a free side chain amino group. Cyclic peptide [(WR)8WK βA] was conjugated through the free side chain amino group of β-alanine with Dox via a glutarate linker to afford [(WR)8WK]bA-Dox conjugate. The conjugate inhibited the cell viability of ovarian adenocarcinoma (SK-OV-3) …

Targeting Neuronal Nitric Oxide Synthase (Nnos) For Melanoma Treatment, Shirley Tong

Pharmaceutical Sciences (PhD) Dissertations

Human cutaneous melanoma is the most aggressive form of skin cancer and the incidence rates have continued to increase over the years. Neuronal nitric oxide synthase (nNOS) produces nitric oxide (NO) has been found to be overexpressed in human melanoma and the expression of nNOS is induced by interferon-gamma (IFN-γ). In our studies, nNOS has been implicated in IFN-γ-stimulated melanoma progression and the inhibition of nNOS using novel inhibitors effectively inhibited IFN-γ-stimulated tumor growth in a xenograft mouse model. Programmed death-ligand 1 (PD-L1) is overexpressed in melanoma and plays an important role in suppressing the immune system ^12-14. Our …

Repeated Targets Of Natural Selection During Ecological Transitions Of Fish Across Salinity Boundaries, Jonathan P. Velotta, Stephen D. Mccormick, Andrew Whitehead, Catherine S. Durso, Eric T. Schultz

EEB Articles

Ecological transitions across salinity boundaries have led to some of the most important diversification events in the animal kingdom, especially among fishes. Adaptations accompanying such transitions include changes in morphology, diet, whole-organism performance, and osmoregulatory function, which may be particularly prominent since divergent salinity regimes make opposing demands on systems that maintain ion and water balance. Research in the last decade has focused on the genetic targets underlying such adaptations, most notably by comparing populations of species that are distributed across salinity boundaries. Here, we synthesize research on the targets of natural selection using whole-genome approaches, with a particular emphasis …

Halodash: The Deep And Shallow History Of Aquatic Life's Passages Between Marine And Freshwater Habitats, Eric T. Schultz, Lisa Park Boush

EEB Articles

This series of papers highlights research into how biological exchanges between salty and freshwater habitats have transformed the biosphere. Life in the ocean and in freshwaters have long been intertwined; multiple major branches of the tree of life originated in the oceans and then adapted to and diversified in freshwaters. Similar exchanges continue to this day, including some species that continually migrate between marine and fresh waters. The series addresses key themes of transitions, transformations, and current threats with a series of questions: When did major colonizations of fresh waters happen? What physiographic changes facilitated transitions? What organismal characteristics facilitate …

Associations Of Dynamic Driving Pressure And Mechanical Power With Postoperative Pulmonary Complications-Posthoc Analysis Of Two Randomised Clinical Trials In Open Abdominal Surgery., Michiel T. U. Schuijt, Liselotte Hol, Sunny G. Nijbroek, Sanchit Ahuja, David Van Meenen, Guido Mazzinari, Sabrine Hemmes, Thomas Bluth, Lorenzo Ball, Marcelo Gama-De Abreu, Paolo Pelosi, Marcus J. Schultz, Ary Serpa Neto

Anesthesiology Articles

Background: While an association of the intraoperative driving pressure with postoperative pulmonary complications has been described before, it is uncertain whether the intraoperative mechanical power is associated with postoperative pulmonary complications.

Methods: Posthoc analysis of two international, multicentre randomised clinical trials (ISRCTN70332574 and NCT02148692) conducted between 2011-2013 and 2014-2018, in patients undergoing open abdominal surgery comparing the effect of two different positive end-expiratory pressure (PEEP) levels on postoperative pulmonary complications. Time-weighted average dynamic driving pressure and mechanical power were calculated for individual patients. A multivariable logistic regression model adjusted for confounders was used to assess the independent associations of driving …

Response: In And Out Of The Game, As Usual, Steven E. Jones

English Faculty Publications

In this response article, I revisit the idea of paratext in video games. I start, however, with the example of a book by Tolstoy, and the textual studies work of McKenzie and McGann, in order to make the point that paratextuality has never been limited to Genette’s rigid definition, even in the case of print texts. Video games foreground what has always been the case: the dynamic, volatile, multidirectional nature of paratexts, which can take you into but also out of the enclosure of the main text (or “game itself”) in unexpected ways. Illustrations include Animal Crossing: New Horizons and …

The theories of motivation and development have shown many theories influencing choices made by people in life. Objectives: This study aims to assess the motivation for choice of specialty among medical doctors (including registrars, residents, and specialists) in Dar es Salaam, Tanzania. Methods: A descriptive cross-sectional study was conducted at Muhimbili University of Health and Allied Sciences, Muhimbili National hospital, and the Aga Khan University Hospital Dar …

Sacred Earth: The Role Of The Natural Divine Within Wendell Berry's "Manifesto", T. Greyson Gurley Ma

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

Kentuckian writer and poet, Wendell Berry, is often associated with environmental literature and advocacy. However, often overlooked, much of Berry’s work is inherently religious in nature, specifically Christian. Berry’s poetry expresses many of his personal beliefs regarding life, spirituality, religion, interconnection, stewardship, and agriculture. In particular, Berry often uses characters to communicate these aforementioned personal ideas. This practice can be seen through his utilization of the character of the Mad Farmer within a great deal of his poetry, including poetry dedicated to the Mad Farmer himself. Although this character expresses many of the same beliefs as Berry, he is not …

The Moth Effect, Kylie Smith

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

This thesis is the start of what I envision to be a full-length memoir. I address multiple themes, specifically family and generational trauma and mental illness. I explore these themes non-linearly, through personal narrative, scientific research, and scene recreations. I begin with an introduction and then move into an essay that explores my experience meeting my estranged sister from the first time. Throughout the essay, I move in and out of this meeting, weaving the encounter together with my own struggles with mental health, research about the Peppered moth species, and scene recreations from the lives of other women in …

European Fantasies: Modernism And Jewish Absence At The Venice Biennale Of Art, 1948-1956, Frances Tanzer

History

This article examines how states with a fascist past - Germany, Austria and Italy - used modernism in the visual arts to rebrand national and European culture at the Venice Biennale of Art after 1945. I argue that post-war exhibitions of modern art, including those at the Biennale, reveal a vast confrontation with Jewish absence after the Holocaust. Christian Democrats and proponents of European integration attempted to reimagine modernism without the Jewish minority that had shaped it in crucial ways. Meanwhile, living Jewish artists resisted their exclusion from the post-war interpretations of modernism, as well as absorbtion of modernism as …

Mapping And Making Meaning From Undergraduate Student Engagement In High-Impact Educational Practices, Bridget G. Trogden, Cazembe Kennedy, Nathan K. Biyani

Publications

Institutions of higher education often have multiple entry points for first-time and transfer college students to engage in high-impact educational practices (HIPs), well documented to advance student learning outcomes. Some students may seek out repeated opportunities while others engage very little or not at all in activities such as student-faculty research, study abroad, internships, first-year cohort programs, service-learning, and the like. When institutions maintain decentralized data and records on students’ participation, obtaining a true understanding of the "who, what, when, and where" of HIPs can be difficult. In this paper, we present an institutional strategy for longitudinal collection of data …

Wolf-elk-aspen interactions: Trophic cascade or trickle?

Elaine Brice

Dan MacNulty

As one of the world’s first National Parks, Yellowstone is renowned for a dynamic landscape that is home to many charismatic species. As one of the few deciduous trees in the Park, aspen is a valuable member of the ecosystem. A century of decline is mostly attributed to elk herbivory of aspen recruitment, while climatic factors are often regarded as unimportant.

Detecting The Intensity Of Denial-Of-Service Cyber Attacks Using Supervised Machine Learning, Abigail Hubbard

Undergraduate Honors Theses

Denial-of-Service (DoS) attacks are aimed at shutting a machine or network down to block users from accessing it. These attacks can be difficult to detect and can cost millions in damages or lost earnings. Since the first DoS attack occurred in 1999, the way DoS attacks have been launched has become more complicated, making them more elusive and harder to detect. The first step to detect and mitigate a DoS attack is for a system to identify the malicious traffic.

In this experiment, we aim to identify the malicious traffic within ten seconds. To do this the project was divided …
