Investigate The Rheological Behavior Of High Viscosity Friction Reducer Fracture Fluid And Its Impact On Proppant Static Settling Velocity, Mohammed Ba Geri, Abdulmohsin Imqam, Andrey Bogdan, Lingjuan Shen

Geosciences and Geological and Petroleum Engineering Faculty Research & Creative Works

The recent and rapid success of using high viscosity friction reducers (HVFRs) in hydraulic fracturing treatments is due to several advantages over other fracture fluids (e.g. linear gel), which include better proppant carrying capability, induce more complex fracture system network with higher fracture length, and overall lower costs due to fewer chemicals and less equipment on location. However, some concerns remain, like how HVFRs rheological properties can have impact on proppant transport into fractures. The objective of this study is to provide a comprehensive understanding of the influence the rheological characterization of HVFRs have on proppant static settling velocity within …

Dynamical Interference In The Vibronic Bond Breaking Reaction Of Hco, Shanyu Han, Xianfeng Zheng, Steve A. Ndengue, Yu Song, Richard Dawes, For Full List Of Authors, See Publisher's Website.

Chemistry Faculty Research & Creative Works

First-principles treatments of quantum molecular reaction dynamics have reached the level of quantitative accuracy even in cases with strong non-Born-Oppenheimer effects. This achievement permits the interpretation of puzzling experimental phenomena related to dynamics governed by multiple coupled potential energy surfaces. We present a combined experimental and theoretical study of the photodissociation of formyl radical (HCO). Oscillations observed in the distribution of product states are found to arise from the interference of matter waves-a manifestation analogous to Young's double-slit experiment.

Helpful for veterans seeking information about financing their business.

Atomistic Simulations Of Nanoindentation Response Of Irradiation Defects In Iron, M. Mustafa Azeem, Qingyu Wang, Muhammad Zubair

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

Radiation response of a material is a consequence of defects' evolution in any radiation damage event. The radiation-induced defects can significantly alter the mechanical properties of a material. Radiation damage initiates from incident neutron by bombardment on solid material causing production and evolution of Frenkel defects. Since voids are formed due to aggregation of a large number of vacancies that cause dimensional changes and hence irradiation-induced swelling. In order to characterize the effect of irradiation defects, we have performed molecular dynamics (MD) simulations to investigate nanoindentation response of point defects and voids in Fe and their effects on mechanical parameters. …

In Situ Mechanical Characterization Of The Mixed- Mode Fracture Strength Of The Cu/Si Interface For Tsv Structures, Chenglin Wu, Congjie Wei, Yanxiao Li

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

In situ nanoindentation experiments have been widely adopted to characterize material behaviors of microelectronic devices. This work introduces the latest developments of nanoindentation experiments in the characterization of nonlinear material properties of 3D integrated microelectronic devices using the through-silicon via (TSV) technique. The elastic, plastic, and interfacial fracture behavior of the copper via and matrix via interface were characterized using small-scale specimens prepared with a focused ion beam (FIB) and nanoindentation experiments. A brittle interfacial fracture was found at the Cu/Si interface under mixed-mode loading with a phase angle ranging from 16.7° to 83.7°. The mixed-mode fracture strengths were extracted …

Increasing Student Perceptions Of Success And Inclusion Through Strategic Programming Of Underrepresented Composers, Joyce J. Beyer

Dissertations and Theses @ UNI

There is a disproportional representation of women and people of color in orchestra and classical music. Both on the stage and in the music being performed, white and male musicians are more prominent than women and people of color. This disproportionality impacts underrepresented people, especially young students.

A study was done to see if introducing students to successful women and people of color who were musicians would increase student perceptions of success and inclusion in orchestra. The study included 37 students from 5 public school orchestra programs. The treatment was a series of pre-designed mini-lessons on underrepresented musicians. Growth was …

Cis/Trans Energetics In Epoxide, Thiirane, Aziridine And Phosphirane Containing Cyclopentanols: Effects Of Intramolecular Oh···O,S,N And P Contacts, Ben E. Smith, Jeremy M. Carr, Gregory S. Tschumper

Chemistry Faculty Research & Creative Works

A recent computational analysis of the stabilizing intramolecular OH···O contact in 1,2-dialkyl-2,3-epoxycyclopentanol diastereomers has been extended to thiiriane, aziridine and phosphirane analogues. Density functional theory (DFT), second-order Møller-Plesset perturbation theory (MP2) and CCSD(T) coupled-cluster computations with simple methyl and ethyl substituents indicate that electronic energies of the cis isomers are lowered by roughly 3 to 4 kcal mol⁻¹ when the OH group of these cyclopentanol systems forms an intramolecular contact with the O, S, N or P atom on the adjacent carbon. The results also suggest that S and P can participate in these stabilizing intramolecular interactions as effectively …

Machine-Learning-Based Pml For The Fdtd Method, He Ming Yao, Lijun Jiang

Electrical and Computer Engineering Faculty Research & Creative Works

In this letter, a novel absorbing boundary condition (ABC) computation method for finite-difference time-domain (FDTD) is proposed based on the machine learning approach. The hyperbolic tangent basis function (HTBF) neural network is introduced to replace traditional perfectly matched layer (PML) ABC during the FDTD solving process. The field data on the interface of conventional PML are employed to train HTBF-based PML model. Compared to the conventional approach, the novel method greatly decreases the size of a computation domain and the computation complexity of FDTD because the new model only involves the one-cell boundary layer. Numerical examples are provided to benchmark …

‘Bloodwood’ And ‘Liminal Spaces, Timeless Places: Abjection, Liminality And Landscape In Australian Gothic Fiction’, Karleah Olson

Theses : Honours

This creative honours project comprises a work of fiction titled ‘Bloodwood’ and an accompanying exegetical essay, exploring the concept of liminal space within the Australian landscape. It investigates the anxieties and consequences of past trauma that linger within the landscape of modern Australia, exploring themes such as time, connection to nature, trauma and grief. Using Julia Kristeva’s abjection theory, particularly her ideas on liminal space, this work addresses the contentious issue of postcolonial theory within the field of literary studies, as well as the concept of grief as a liminal process. These ideas are explored through the storylines of three …

Image-Based Sexual Abuse: A Qualitative Exploration Of The Lived Experience And Perceived Consequences For Women, Brienna L. Webb

Theses : Honours

Being a highly convoluted and contemporaneous issue, defining and conceptualising image based sexual abuse has proved difficult for scholars. Although research on image-based sexual abuse is limited, previous inquiries have identified serious consequences and accumulative harms for affected individuals. I aimed to explore the lived experience and consequences of image-based sexual abuse as identified by women, in an attempt to taper the research dearth on this phenomenon. An in-depth qualitative phenomenological exploration of seven women’s experiences of image-based sexual abuse saw five overarching themes emerge from participants’ discourse. The themes comprised mental health impacts; perceptions of self; loss of control; …

Cultural Diversity And Children’S Literature: Kindergarten Educators’ Practices To Support Principles Of Cultural Diversity Through Book Sharing, Helen Joanne Adam

Theses: Doctorates and Masters

Since Australia became a signatory to the United Nations Convention on the Rights of the Child in 1989, the importance of recognising, valuing and respecting a child’s family, culture, language and values has been increasingly articulated in education policy. Diversity and inclusion are now central themes guiding the principles and quality measures of early childhood education and care as encompassed by the National Quality Framework, including both the National Quality Standard and the Early Years Learning Framework (Early Childhood Development Steering Committee, 2009). Children’s literature can be a powerful tool for extending children’s knowledge and understandings of themselves and others …

Intergenerational Influences Of Hunger And Community Violence On The Aboriginal People Of Western Australia: A Review, Francesca Robertson, David Coall, Dan Mcaullay, Alison Nannup

Research outputs 2014 to 2021

There is a consensus in the literature that hunger and community violence inaugurates adverse health impacts for survivors and for their descendants. The studied cohorts do not include Western Australian Aboriginal people, although many experienced violence and famine conditions as late as the 1970s. This article describes the pathways and intergenerational impacts of studied cohorts and applies these to the contemporary Western Australian context. The authors found that the intergenerational impacts, compounded by linguistic trauma, may be a contributor to current health issues experienced by Aboriginal people, but these are also contributing to the resurgence in population numbers.

Ell's Science Meaning Making In Multimodal Inquiry: A Case-Study In A Hong Kong Bilingual School, Melanie Williams, Kok-Sing Tang, Mihye Won

Research outputs 2014 to 2021

This paper reports on a multimodal teaching approach delivered to grade 5 elementary students in a bilingual school in Hong Kong, as part of a larger research study aimed at supporting English Language Learners (ELLs) in science class. As language demands of reading, writing and talking science place additional challenges on ELLs, there is much research interest in exploring the use of multiple modes of communication beyond the dominant use of verbal and written language. Research has shown that students develop a better scientific understanding of natural phenomena by using and alternating between a variety of representations. Yet, questions remain …

Expanding University Entrepreneurial Ecosystems To Under-Represented Communities, Emma O'Brien, Thomas M. Cooney, Per Blenker

The total sprint (≥22 km·h^-1) distance (TSD), the number of sprints (NOS) classified as length (<20 >m, ≥20 m) and relative speed thresholds (90%), the between-sprint duration and the number of repeated-sprint bouts (≥2 sprints in ≤60 s) were analyzed. The NOS was 22.2 ± 6.8 accumulating …

Activity Monitoring In Professional Soccer Goalkeepers During Training And Match Play, Victor Moreno-Pérez, Shane Malone, Lluís Sala-Pérez, Manuel Lapuente-Sagarra, Miguel Angel Campos-Vazquez, Juan Del Coso

Articles

The purpose of the present study was to quantify the external load of professional soccer goalkeepers. Twenty professional goalkeepers participated in the study. Data were classified according to the number of days before or after the match day (MD) as follows: MD-4, MD-3, MD-2, MD-1 for the sessions before the match, and MD+1 for the session after the match. The total running distance covered (TD), the high metabolic load (HMLD), the number of high metabolic load efforts (HMLE) were progressively reduced from MD-4 to MD-1 but the values of these variables were always inferior to MD (ES: -3.79 to −1.11). …

The Incoherence Of Yhwh In Jeremiah As An Opening For Hermeneutical Possibilities: Deconstructing Traditional Methodological Entanglements With Text-Linguistics And Psychology, Oliver Glanz, Torben Bergland

Andrews University Seminary Studies (AUSS)

This article pursues three objectives and is interdisciplinary in nature, bringing together the skill sets of biblical scholarship and psychology. First, it seeks to critically examine the hermeneutical frameworks brought to the reading of apparently incoherent texts in Jer 7 and 8:18–9:10. Why and how are scholars finding meaning in these texts when their exegetical procedures remain limited to the tools offered by traditional historical-critical and conservative historical-grammatical methods? We argue that fruitful theological analysis of Jeremiah’s incoherent texts is compromised when following the hermeneutics of either higher-critical or traditional evangelical schools. Second, we demonstrate that the prophetic text of …
