Decolonizing The Western Perception Of Afghan Women: A Feminist Critique, Parwana Azimi

Honors Program: Senior Projects (Public)

Abstract: Feminist theory and activism have often been reduced to singular movements from Western literature and history. Thus, the exploration of Feminist theory is often limited to Western ideology and values. In doing so, Western Feminism has primarily promoted the rights of Women living in developed countries while leaving women in developing countries or otherwise out of the discussion of women’s rights and status. Most often, women's rights struggles outside of the West are seen as colonial projects which portray Muslim women as helpless and requiring liberation from their cultures. A prominent example of this is the case of Afghan …

Drag Reduction In Channel Flow Configurations For Laminar And Turbulent Flow Past Superhydrophobic Surfaces, Henry Louis Ems

Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–

In this work, we present friction drag reduction in minichannel laminar flow past superhydrophobic metallic surfaces. Femtosecond laser surface processing (FLSP), a one-step scalable method, was used to create permanent microscale and nanoscale structures on 316 stainless steel plates. The resulting superhydrophilic plates were covered by tall (215 μm) or short (27 μm) structures. The FLSP plates were then transitioned to superhydrophobic by evaporative deposition of a fluorinated silane, a low surface energy coating. Using purified water, the friction factor was obtained by measuring pressure drop along a minichannel with a rectangular cross section for flow rates corresponding …

Exploring Subtype C Hiv-1 Tissue Reservoirs And The Impact Of Cannabis Use In Virally Suppressed African Individuals, Zhou Liu

Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–

Antiretroviral therapy (ART) has dramatically prolonged the lives of people living with HIV (PLWH), but it is not curative as it cannot eliminate integrated HIV-1 proviruses in different tissue reservoirs. Even though subtype C HIV-1 accounts for almost half of global HIV-1 infections, few studies had evaluated HIV-1 reservoirs for this subtype. Many co-factors, including the lifestyle factor cannabis use, have been investigated for their potential effects in HIV-1 infection. However, only limited information exists regarding cannabis’s effects on HIV-1 infections in vivo, and the impact of cannabis use on HIV-1 parenchymal tissue reservoirs is unexplored.

Aggregate Games: Computations And Applications, Jared Soundy

Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–

Existing computational game theory studies consider compact representations of games that capture agent interaction in real-world environments and examine computation aspects of computing equilibrium concepts to analyze or predict agent behavior.

One of the most well-studied representations that capture many commonly studied real-world environments is aggregate games. Aggregate games, first systematically studied by Nobel laureate Reinhard Selten, have various applications in modeling the decision-making interdependence of agents, where each agent’s utility function depends on their own actions and the aggregations or summarizations of the actions of all agents. These applications include Cournot oligopoly competition, public good contribution, and voting, where …

The Impact Of A Pgym Variant On Myophosphorylase Deficiency In Red Angus Composite Cattle And Changes In The Skeletal Muscle Transcriptome Due To The Intramuscular Administration Of Lidocaine In Wether Lambs, Mackenzie Christin Batt

School of Biological Sciences: Dissertations, Theses, and Student Research

Project 1 focused on eight calves in a Nebraska herd (composite Simmental, Red Angus, Gelbvieh) that displayed exercise intolerance during forced activity. Available sire pedigrees contained a paternal ancestor within 2-4 generations in all affected calves. Pedigrees of the calves’ dams were unavailable, however, the cows were ranch-raised and retained from prior breeding seasons, where bulls used for breeding occasionally had a common ancestor. Therefore, it was hypothesized that a de novo autosomal recessive variant was causative of exercise intolerance in these calves. A genome-wide association analysis followed by whole-genome sequencing led to the identification of a variant in the …
