Seasonal Variation In Mitochondrial Bioenergetics Of The Bluegill Sunfish, Lepomis Macrochirus, From A Shallow Midwest River, Derick Isaac Lamptey

Masters Theses

As average global temperature increase, the frequency and magnitude of extreme temperatures in shallow aquatic ecosystems are more ubiquitous. In order to understand how these changing thermal regimes affect aquatic ectotherms, it is essential to develop studies evaluating the response of ectotherms to seasonal fluctuating thermal regimes. Previous studies on fluctuating temperature regimes have reported an increased physiological stress leading to morphological, behavioral and biochemical adaptations. From the latter, the adaptive capacity and seasonal performance associated with optimal function of the oxidative phosphorylation system (OXPHOS) are key for species persistence. However, studies on this matter are scarce. This study explores …

Assessment Of The Immune Response To Posthodiplostomum Minimum Infection In Bluegills, Olamide S. Olayinka

Masters Theses

Bluegills (Lepomis macrochirus) are common intermediate hosts for white grub (Posthodiplostomum minimum). They tolerate heavy infections with minimal effect on condition and continue to accumulate metacercariae as they age. This suggests that any immune response to this parasite might not be effective. This study was conducted to better understand the immune mechanisms underlying P. minimum infection in bluegills.

Infected organs (liver, kidney, and heart) were examined histologically, and serum from infected fish was tested for antibodies to white grub. Juvenile flukes were recovered from isolated metacercarial cysts. Polyclonal antibodies were produced in mice against white grub …

Monitoring Temporal Trends In Catostomidae Larvae In Large Sized River Tributaries, Kellie Nicole Hanser

Masters Theses

Large river ecosystems can support a complex network of tributaries that provide optimal habitat for fish reproduction. Anthropogenic alteration of rivers and tributaries has been shown to have adverse effects on river fish communities, but few studies have focused on the effects river regulation may have on the reproduction of native suckers (Family Catostomidae). In this study, I evaluated differences in biotic and abiotic factors associated with catostomid reproduction between tributaries of an altered and free-flowing river. I conducted ichthyoplankton sampling using drift nets and larval push nets in tributaries of the Illinois River, which is regulated for navigation, and …

Examining Diversity In The Monarch Award, Michele Mcdaniel

Masters Theses

Bigheaded Carp Spatial Reproductive Dynamics And Population Genetics In Large River Tributaries, Samuel J. Schaick

Masters Theses

Fisheries managers are devoting considerable effort, time, and funding towards limiting the spread of invasive Bighead and Silver (bigheaded) Carp. A better understanding of factors that influence spatial patterns of bigheaded carp reproduction can help fisheries managers prevent their spread. To examine factors that influence spatial patterns of reproduction, we sampled ichthyoplankton using drift nets and larval push nets in three tributaries of the Illinois and Wabash Rivers March-September 2016-2018. We compared relative abundances of bigheaded carp eggs and larvae among tributaries using catch per unit effort (CPUE). Abiotic data were analyzed from individual study tributaries and pooled among tributaries …

A Cloning Strategy For Expression Of Fungal Hemicellulases In Plant Systems, Amer Alrudayan

Masters Theses

Lignocellulosic biomass is notoriously difficult to deconstruct into lignin, hemicellulose, and cellulose fractions without the use of biochemical, chemical, and/or mechanical pretreatments. These pretreatment strategies add operational cost and in some cases produce hazardous waste that poses health and safety risks. Direct biological pretreatment from biomass-degrading bacteria and fungi may significantly reduce the costs and risks associated with these traditional strategies due to the innate ability of these organisms to modify plant cell walls. An additional measure that could further reduce the expenses associated with lignocellulosic biomass fractionation is genetic modification of the lignocellulosic feedstocks, which can be accomplished by …

Get Out (2017), Us (2019), And Jordan Peele's New Black Body Horror, Brady Simenson

Graduate Research Theses & Dissertations

This thesis provides an analysis of Jordan Peele’s films, Get Out (2017) and Us (2019). The thesis contextualizes Get Out and Us as part of a protracted cultural conversation regarding monstrous images of the cinematic black body that began with Hollywood’s early monster films and continued into the culturally subversive era of blaxploitation horror films. While blaxploitation cinema reclaimed images of the racial Other that had been represented in the early creature feature subgenre, no such notable movement has subverted the more recent body horror subgenre. Jordan Peele’s Get Out and Us shift this subgenre toward racially inverted body horror. …

Interfaces In Lead-Free Tin Perovskite Photovoltaics: An Investigation Of Energetics, Ion Mobility, Surface Modification, And Performance, Alex Boehm

Theses and Dissertations--Chemistry

Halide perovskites have generated tremendous interest as low-cost semiconductors for optoelectronics, such as photovoltaics, lasers, and light emitting diodes due to their extraordinary optical and transport properties. Perovskite photovoltaics in particular have demonstrated a meteoric rise in power conversion efficiencies and drawn considerable interest as a next-generation solar energy technology. The rapid development has centered around lead-based derivatives, and concerns regarding the toxicity of lead has sparked interest in low toxicity and more environmentally friendly perovskite derivatives. In this regime tin (Sn) is regarded as a prominent alternative owing to the ideal bandgap and reduced toxicity exhibited by Sn-halide perovskites. …

Experiments With Suppression: The Evolution Of Repressive Legality In Britain In The Revolutionary Period, Christopher M. Roberts

Loyola of Los Angeles International and Comparative Law Review

This article is concerned with the structure of repressive governance, and how it has evolved historically. It examines this theme through an exploration of the manner which repressive laws and institutions evolved in Britain over the course of the late eighteenth century. In particular, it reviews the various measures that British authorities utilized and relied upon in order to confront a growing wave of calls for social and political reforms. These included a policy of aggressive prosecutions of dissidents; the creation of new institutions such as the Home Office designed to enhance the powers of the central authorities; extralegal measures …

Hijacking The Fusion Complex Of Human Parainfluenza Virus As An Antiviral Strategy, T. C. Marcink, E. Yariv, K. Rybkina, V. Más, F. T. Bovier, A. Des Georges, A. L. Greninger, C. A. Alabi, M. Porotto, N. Ben-Tal, A. Moscona

Advanced Science Research Center

The receptor binding protein of parainfluenza virus, hemagglutinin- neuraminidase (HN), is responsible for actively triggering the viral fusion protein (F) to undergo a conformational change leading to insertion into the target cell and fusion of the virus with the target cell membrane. For proper viral entry to occur, this process must occur when HN is engaged with host cell receptors at the cell surface. It is possible to interfere with this process through premature activation of the F protein, distant from the target cell receptor. Conformational changes in the F protein and adoption of the postfusion form of the protein …

Adaptive Filtration Of The Uav Movement Parameters Based On The Aoa-Measurement Sensor Networks, Igor Tovkach, Serhii Zhuk

International Journal of Aviation, Aeronautics, and Aerospace

Currently, the urgent task is to assess the small-sized maneuvering UAVs movement parameters. The location of an unknown UAV as a radio source can be determined using AoA measurements of the wireless sensor network. To describe the movement of a maneuvering UAV, a model is used in the form of a dynamic system with switching in discrete time. The values of switching variable determine type of UAV movement. To synthesize trajectory filtering algorithms, the Markov property of the extended process is used, which includes a vector of UAV movement parameters and a switching variable. The optimal trajectory filtering algorithm describes …

Mapping Land Use And Land Cover Change And Its Impact On Landscape Structure And Amphibian Functional Connectivity In The Prairie Pothole Region, Taylor Holm

Theses and Dissertations

Monitoring land use and land cover (LULC) change and its effect on habitat availability and connectivity is crucial for species conservation and management. This is most efficiently accomplished at a sufficiently broad scale using remote sensing technology. Current approaches benefit from freely available data sources such as National Land Cover Database (NLCD), derived from 30 m Landsat imagery. However, temporal frequency and spatial resolution of NLCD may be insufficient for some applications. Specifically, 30 m resolution data may not detect small or narrow landscape features that may be important habitat for small animals such as amphibians. Other available data sources, …

Mountain Lions In North Dakota: A Public Opinion Survey, Theodore A. Darnell

Theses and Dissertations

Breeding mountain lion (Puma concolor) populations currently inhabit the western portion of North Dakota. In recent years, apparent increases in human-lion interactions across North Dakota, and other Midwest states, have challenged wildlife managers who strive to balance biological and social carrying capacities of these animals. In 2019, we surveyed 2,000 residents of North Dakota, USA, using a self-administered mail survey to discern knowledge of and attitudes towards mountain lions, and to explore whether the presence of these animals would influence decisions to recreate in western North Dakota. Our questionnaire included 12 questions designed to ascertain respondent attitudes towards mountain lions. …

Wastewater Treatment Fatty Acids For Biodiesel Production, Zachary Christman

Department of Agronomy and Horticulture: Dissertations, Theses, and Student Research

Wastewater scum is the thick oily substance that floats on top of the primary and secondary tanks within a wastewater treatment plant. Scum has a 30% to 60% lipid content making it an excellent resource for the biodiesel industry. Also the use of scum would reduce the cost of current management practices such as landfill disposal or incineration. In this article there is an overview of lipid byproducts currently being produced at wastewater treatment plants today. This is followed by a presentation showing a full length process for turning wastewater scum into biodiesel raw material.
