Fracture Initiation And Propagation In Shale Formations With Anisotropic Toughness, Nourelhouda Benouadah

Theses and Dissertations

Hydraulic Fracturing (HF) is the prime technology for enhanced production from shale plays. Due to their laminations at different scales, shales exhibit transverse isotropic (TI) properties. In most cases the lamination planes are nearly horizontal in shales setting with the symmetric axes being vertical, therefore, shales are referred to as TI vertical (TIV) rocks. This influences significantly the initiation and propagation of the induced fracture during fracturing operation. For instance, accurate estimation of the fracture initiation pressure (FIP) and fracture morphology is essential to ensure optimum hydraulic fracturing design in unconventional reservoirs. However, majority of studies of HF modelling in …

An Exploratory Analysis Of A Time Synchronization Protocol For Uas, Marcos Fernandez-Tous

Theses and Dissertations

This dissertation provides a numerical analysis of a Receiver Only Synchronization (ROS) protocol which is proposed for use by Unmanned Aircraft Systems (UAS) in Beyond Visual Line of Sight (BVLOS) operations. The use of ROS protocols could reinforce current technologies that enable transmission over 5G cell networks, decreasing latency issues and enabling the incorporation of an increased number of UAS to the network, without loss of accuracy. A minimum squared error (MSE)-based accuracy of clock offset and clock skew estimations was obtained using the number of iterations and number of observations as independent parameters. Although the model converged after only …

A Novel Numerical Model For Transient Mixed-Flow Analysis In Pipe And Conduit Systems, David B. Khani

Theses and Dissertations

While responding to a wet weather flow event, stormwater pipe systems experience complex transient flow in which both open channel and pressurized flow regimes may coexist. The resulting transient flows may induce significant positive and negative pressure surges that can be intense enough to compromise the integrity of the system such as pipe rupture or flooding the streets and damage to properties. Unfortunately, available off-the-shelf software such as InfoWorks, Mike Urban, etc. are not comprehensive enough to capture all features of the resulting transient flows. When the elastic feature of the flow system becomes of significant importance, these models fail …

The Driving Forces Of Academic Integrity: A Survey Of Communication Disorder Students, Mary Ellen Huston

Theses and Dissertations

Academic dishonesty has been a pervasive problem in universities for decades, however, there has been limited research linking allied health students to specific cheating behaviors. For students studying to enter allied health fields, academic dishonesty is problematic as the health and safety of their clients is at risk.

Mosquito Fauna And Prevalence Of Avian Malaria In The Turtle Mountains, North Dakota, Kelsey J. Morin

Theses and Dissertations

Avian malaria is a disease caused by intracellular parasites transmitted by mosquitoes and is detrimental to individual birds and their populations. Although it is sub-lethal in most instances, avian malaria can result in anemia, lower fertility, and reduced migration ability. The Turtle Mountains is a unique ecoregion in North Dakota and provides habitat for various bird and mosquito species that differ from other parts of the state. Previous research has defined the mosquito fauna and occurrence of avian malaria in the Red River Valley region of eastern North Dakota and Northwest Minnesota; however, no research has been conducted in the …

The Key Actions Of School Leaders That Contribute To Effective Implementation Of Restorative Practice, Amy L. Starzecki

Theses and Dissertations

A growing number of students are faced with significant social, emotional, and behavioral needs that translate into a variety of problem behaviors in schools. These behaviors often result in suspension or expulsion. Exclusionary discipline practices such as suspension and expulsion negatively impact student outcomes and achievement. Additionally, these practices are often disproportionately applied to specific student populations (i.e., students of color, students with disabilities, and boys). Schools across the United States are looking for alternatives to exclusionary discipline practices that remove students from classroom instruction. Restorative practice can be an alternative to traditional punitive discipline approaches by promoting strong interpersonal …

Voice Of The Voiceless: Alumni Of A Rural North Dakota School Respond To Traditional Urban Solutions For Rural Education, Thomas Warman

Theses and Dissertations

Equitable school district funding is a constant challenge for state legislatures. When budgets must be trimmed, the panacea for state legislatures has traditionally been approached strictly through the lens of economic efficiency. Since small rural schools typically have a greater per pupil cost, they are often forced into consolidating with nearby districts based on size alone. This research looked at how North Dakota should approach any changes to N.D. Cent. Code § 15.1-12 (n.d.), dealing with mandatory consolidation. Two theoretical frameworks were used in this research. The first, isomorphism, examined definitions of proper school district size and have been defined …

In many cases, workplace culture has become more positive, employee mental health has improved, retention has increased, and collaboration and stakeholder partnerships have flourished. This qualitative study’s intent was to explore the implementation of a coaching framework inspired by executive and transformational coaching in public elementary schools. Novice principals of three North Dakota elementary schools were selected as participants for this study. These principals had a …

The Effect Of Mineral Composition On Elastic Properties Of The Bakken Formation In The Williston Basin, North Dakota, John Albert Harju

Theses and Dissertations

Hydrocarbon production from tight oil and/or shale plays requires drilling horizontal wells with very long laterals and hydraulic fracturing operations to stimulate the reservoirs which have generally very low porosity and permeability. A great amount of experience has been accumulated over the past two decades in the North America from production of these types of reservoirs. The Bakken formation in North Dakota, is one of the largest tight oil producers in the U.S.A. and currently ranks as the second largest producer of oil in the nation. The Bakken formation is divided into the upper and lower shale members, which are …

Is United States (U.S.) Policy Sufficient To Develop Earth-Moon Economic Zone Infrastructures By 2049?, Terry Jaggers

Theses and Dissertations

The nation first-to-develop infrastructures in the future Earth-Moon Economic Zone will set the standards that shape and govern use by others, increasing both economic and national power. Current U.S. economic and national power is built upon a legacy of infrastructure leadership on Earth and in Earth orbit. However, China has a goal to supplant U.S. infrastructure leadership on Earth and establish leadership before the U.S. in the Earth-Moon Economic Zone by 2049. While the U.S. acknowledges China’s terrestrial infrastructure goals as an economic challenge, China’s space infrastructure goals appear to be met as either a military challenge in Earth orbit, …

Librarian Publications

We study the process involved in diminishing consumer grudges against an industry. Through a qualitative case study of an organization tasked with changing consumer’s negative perceptions and beliefs about the Canadian agriculture industry, we uncover how the process of decaying grudges involves presenting information, creating credibile sources, and building positive affect. Our findings extend Thota and Wright’s (2006) grudgeholding decay framework.

Investigating Information Structure And Word Order In Latin Poetry: An Analysis Of Epigrams, Justin Riley Soderholm

Theses and Dissertations

This thesis examines the epigrammatic verses of the Latin poet Marcus Valerius Martialis (Martial). The emphasis is on the order of basic constituents and information structure, in particular, the concepts of sentence articulation and focus structure as modelled by Lambrecht (1994).

I categorize clauses from roughly 200 lines of epigrammatic verse by the sentence articulations topic-comment, in which propositions have predicate focus, identificational, in which propositions have argument focus, and thetic, in which whole propositions are in focus. For each articulation, I also present various examples demonstrating the variety of word orders in each. Additionally, this study examines some patterns …

Measuring Cross-Cultural Engagement Of Those Using The Growing Participator Approach, Cheryl Lea Cross

Theses and Dissertations

The Growing Participator Approach (GPA) is a language-learning approach used among global professionals living cross-culturally. Developer Greg Thomson claims that through the GPA, learners grow as active participants in their new culture by learning language primarily in relationship. Because cultural participation is central to GPA, measuring social engagement is the most appropriate form of evaluation. This research seeks to answer the questions: (1) Does focused language learning using the GPA correspond with a high degree of social integration in the host community? (2) Does the use of scales from other academic fields help evaluate social engagement for language learners?

Ecosystem transformation involves the emergence of persistent ecological or social–ecological systems that diverge, dramatically and irreversibly, from prior ecosystem structure and function. Such transformations are occurring at increasing rates across the planet in response to changes in climate, land use, and other factors. Consequently, a dynamic view of ecosystem processes that accommodates rapid, irreversible change will be critical for effectively conserving fish, wildlife, and other natural resources, and maintaining ecosystem services. However, managing ecosystems toward states with novel structure and function is an inherently unpredictable and difficult task. Managers navigating ecosystem transformation can benefit from considering broader objectives, beyond a …

Enhancing Diversity In Nursing Education, Ellen Steidl

Nursing Capstones

Diversity in the nursing workforce lags behind the demographic of the national population; therefore, diversity of the student population must be enhanced in nursing education. While racial minority groups account for 40% and men account for 50% of the total population, only 20% of racial minority groups and 9% of men are represented in nursing. The Transcultural Nursing Theory serves as the theoretical framework for this study. A thorough review of the literature was conducted and analyzed. Several barriers to achieving diversity in nursing education exist including issues with recruitment and retention of diverse populations. Strategies for effective implementation techniques …
