Dual Nature Of Magnetic Nanoparticle Dispersions Enables Control Over Short-Range Attraction And Long-Range Repulsion Interactions, Ahmed Al Harraq, Aubry A. Hymel, Emily Lin, Thomas M. Truskett, Bhuvnesh Bharti

Faculty Publications

Competition between attractive and repulsive interactions drives the formation of complex phases in colloidal suspensions. A major experimental challenge lies in decoupling independent roles of attractive and repulsive forces in governing the equilibrium morphology and long-range spatial distribution of assemblies. Here, we uncover the ‘dual nature’ of magnetic nanoparticle dispersions, particulate and continuous, enabling control of the short-range attraction and long-range repulsion (SALR) between suspended microparticles. We show that non-magnetic microparticles suspended in an aqueous magnetic nanoparticle dispersion simultaneously experience a short-range depletion attraction due to the particulate nature of the fluid in competition with an in situ tunable long-range …

Teaching The Relationship Between Multiplication And Division Through Differentiated Instructional Strategies, Teagan Vaughan

Theses/Capstones/Creative Projects

This capstone project reports the differentiated instructional strategies that were integrated throughout a math unit. The capstone will report the effectiveness of two instructional strategies that were integrated into a math unit that focused on students’ understanding of the relationship between multiplication and division. The math unit had 12 lessons taught over three weeks between the pre-and post-assessment. I will report how the strategies worked and the effect the strategies had on students learning. I collected and analyzed the pre/post-test data and found that nonlinguistic representations and multi-level questioning are effective instructional strategies for increasing student learning.

Assessing Aerodynamic Loads On Low-Rise Buildings Considering Reynolds Number And Turbulence Effects: A Review, Md Faiaz Khaled, Aly Mousaad Aly

Faculty Publications

This paper presents an extensive review of existing techniques used in estimating design wind pressures considering Reynolds number and turbulence effects, as well as a case study of a reference building investigated experimentally. We shed light on the limitations of current aerodynamic testing techniques, provisions in design standards, and computational fluid dynamics (CFD) methods to predict wind-induced pressures. The paper highlights the reasons for obstructing the standardization of the wind tunnel method. Moreover, we introduce improved experimental and CFD techniques to tackle the identified challenges. CFD provides superior and efficient performance by employing wall-modeled large-eddy simulation (WMLES) and hybrid RANS-LES …

Religiosity And Midwestern Lgbtq+ Homeless Youth, Alecia Keller, Nancy Kelley

Theses/Capstones/Creative Projects

Previous investigations have focused on the intersections of LGBTQ+ youth and religion, homelessness and religion, or homeless LGBTQ+ youth, without recognizing the multiple intersections that make up each LGBTQ+ youth’s identity. The purpose of this study was to gain more insight into how being homeless, identifying as LGBTQ+, and growing up with some religion played a role in transitional-aged (ages eighteen to twenty-five) youths’ lives. After working with Youth Emergency Services (YES) in Omaha, Nebraska, and conducting interviews with LGBTQ+ youth who were previously homeless, similar topics emerged among participants. Three participants were evicted from their homes because of their …

Patterns And Predictors Of Adherence To Breast Cancer Screening Recommendations In Alberta's Tomorrow Project, Olivia K. Loewen, Navjot Sandila, Grace Shen-Tu, Jennifer E. Vena, Huiming Yang, Kara Patterson, Jian Yi Xu

Faculty Publications

Breast cancer screening is an important prevention component as it can reduce cancer mortality and improve survival. Understanding patterns of adherence to screening recommendations is essential to guide health promotion strategies and policy implementation efforts. The 1999 Alberta screening guidelines were used to determine screening status for eligible female participants in Alberta's Tomorrow Project (n = 4,972), a longitudinal province-based cohort. Screening patterns were derived based on screening status assessed at enrollment (2001–2008) and follow-up (2008–2011). Information on reason for screening was also collected at each time point. Multinomial logistic regression was used to assess potential predictors of adherence to …

Personalized Breast Cancer Onset Prediction From Lifestyle And Health History Information, Shi Ang Qi, Neeraj Kumar, Jian Yi Xu, Jaykumar Patel, Sambasivarao Damaraju, Grace Shen-Tu, Russell Greiner

Faculty Publications

We propose a method to predict when a woman will develop breast cancer (BCa) from her lifestyle and health history features. To address this objective, we use data from the Alberta's Tomorrow Project of 18,288 women to train Individual Survival Distribution (ISD) models to predict an individual's Breast-Cancer-Onset (BCaO) probability curve. We show that our three-step approach-(1) filling missing data with multiple imputations by chained equations, followed by (2) feature selection with the multivariate Cox method, and finally, (3) using MTLR to learn an ISD model-produced the model with the smallest L1-Hinge loss among all calibrated models with comparable C-index. …

A Systematic Literature Review Of Anti-Discrimination Design Strategies In The Digital Sharing Economy, Miroslav Tushev, Fahimeh Ebrahimi, Anas Mahmoud

Faculty Publications

Applications of the Digital Sharing Economy (DSE), such as Uber, Airbnb, and TaskRabbit, have become a main facilitator of economic growth and shared prosperity in modern-day societies. However, recent research has revealed that the participation of minority groups in DSE activities is often hindered by different forms of bias and discrimination. Evidence of such behavior has been documented across almost all domains of DSE, including ridesharing, lodging, and freelancing. However, little is known about the underlying design decisions of DSE platforms which allow certain demographics of the market to gain unfair advantage over others. To bridge this knowledge gap, in …

Roots And Branches: Mimetic Reconstruction Of Women's History Through Nature In Post-Colonial Literature, Jessica D'Albero

Student Theses

Composed similarly to a mini book, this unconventionally structured thesis centralizes on how contemporary female authors, particularly Aurora Levins Morales and Yaa Gyasi, can rebuild gaps in undocumented women’s history through a fusion of nature within post-colonial fiction. A severe lack of preservation exists regarding women’s historical records due to centuries of facing oppression and dual colonization within domestic and public spheres. As a result, women’s memories have become misdirected. These memory gaps can be mimetically refurbished through fictional reconstruction to reimagine simulated pieces to the puzzle of women’s past. The paper divides into two sections, discussing first the idea …

A Drought-Tolerant Nitrogen-Fixing Symbiont For Sustainable Soybean Production, Christian James Peterson

Biology Dissertations - Archive

Bradyrhizobia are an ideal model organism to study plant-microbe interactions due to dual lifestyles as free-living soil organisms and as endosymbionts for valuable cropping systems in agriculture. Farmers have been utilizing the Soybean-Bradyrhizobium japonicum mutualism for decades to revitalize marginal soils, increase yields, and establish a regenerative approach to farming by mitigating the use of synthetic nitrogenous fertilizers. The largest impediment to bio-fertilizer success is desiccation (e.g., drought) stress before the symbiosis can be established. Due to climate change, fluctuating high temperatures and drought occur seasonally in many growing regions and are becoming a growing concern for modern agriculture. Thus, …

An Access And Equity Ranking Of Public Law Schools, Christopher L. Mathis

Grantee Research

Over the past few decades, several comprehensive ranking systems, including the influential U.S. News and World Report’s Best Law Schools rankings, have emerged to provide useful information to prospective law students seeking to enroll in law school. These ranking systems have defined what is measured as “quality” and what outcomes law schools focus on to gain a better position in the ranking. These rankings fail to measure what many law schools claim to be one of their longstanding goals—diversity, access, and equity.

One of the problematic and shocking reasons U.S. News cites for not including diversity measures in the …
