Collision Work Performed By Patients With Peripheral Artery Disease, Alex Dzewaltowski, Sara A. Myers, Jason M. Johanning, Iraklis I. Pipinos

UNO Student Research and Creative Activity Fair

The goal of this study was to assess the differences in collision work performed by healthy, aged-matched controls compared to patients with peripheral artery disease (PAD) to provide foundations for an eventual exoskeleton design. Collision work is energy dissipated into the surrounding environment from impact, in this study’s case, upon heel strike. When designing an exoskeleton for patients with PAD, harvesting energy lost to collision work could be a valuable mechanism to improve walking performance. Devices designed to utilize the normally dissipated energy for assisting propulsion to improve walking performance are under-explored [1, 2]. The purpose of this study was …

Physiological Response To Exercise With Naturally-Occurring Carbon Dioxide Exposure, Megan Johnson

UNO Student Research and Creative Activity Fair

BACKGROUND: Carbon dioxide (CO₂) plays a normal part in gas exchange and acid-base equilibrium in the human body. With added stress or exposure, CO₂ levels can accumulate in the blood and tissues, causing hypercapnia. Research has shown that exposure to CO₂ at 4% or 40,000 ppm will cause cardio-respiratory changes, both at rest and during exercise. Lower levels may still cause changes under conditions of added stress, but this has not been elucidated. Preliminary data from our laboratory chamber suggests physiological changes at levels of CO₂ reaching 0.08% or 8,000 ppm during experiments with exercising …

Effect Of Local Cold Application During Exercise On Mitochondrial Gene Expression, Ben Meister

UNO Student Research and Creative Activity Fair

BACKGROUND: Different modes of exercise and temperatures can elicit different responses in mitochondrial gene expression. Stresses including exercise and cold exposure act to trigger the transcription of genes associated with mitochondrial growth (biogenesis). Traditional endurance exercise is known to have a potent effect on mitochondrial growth biogenesis. However, limited knowledge exists on the effect of local cold application during endurance exercise. Additionally, it is currently unknown how cold exposure impacts mitochondrial breakdown (mitophagy). PURPOSE: Therefore, the purpose of this study is to determine the impact of local muscle cooling during endurance exercise on human skeletal muscle gene expression related to …

Estimating Variations In Metabolic Cost Within The Stride Cycle During Level And Uphill Walking, Arash Mohammadzadeh Gonabadi

UNO Student Research and Creative Activity Fair

Indirect calorimetry provides the average cost of a stride cycle and prevents from identifying which part of the gait cycle causes increased metabolic cost in patients, however, recent simulation methods allow estimating the time profile of metabolic cost within the stride cycle. In this study, we compare the estimations of the time profile of the metabolic cost of two simulation methods for level and uphill walking. We used kinematic, kinetic and electromyography data from level and uphill walking (one participant) to estimate the time profiles of metabolic cost using the muscle-level metabolic model of Umberger using electromyography and kinematic data …

UNO Student Research and Creative Activity Fair

Halee Keller, Robert Shute, Dustin Slivka

University of Nebraska at Omaha, School of Health and Kinesiology, Omaha, NE

BACKGROUND: Mitochondria are highly concentrated in skeletal muscle tissue, and undergo damage from ROS during metabolic processes. This damage is often left unrepaired and leads to mitochondrial dysfunction, which has been linked to many common diseases. Exercise training increases mitochondrial development within skeletal muscle tissue and thus may be protective. Environmental temperature, when paired with exercise may provide an even greater effect than exercise alone. PURPOSE: The purpose of this study is to analyze the effects of three weeks of exercise …

A Correlation Network Model For Managing Safety And Performance Issues In Bridges And Civil Infrastructures, Prasad Chetti

UNO Student Research and Creative Activity Fair

Many recent studies have shown that a large percentage of bridges in many parts of the world have low safety rating. National Bridge Inventory (NBI) database contains the information of more than 600,000 bridges, where each bridge has 116 parameters. Current safety inspections require bridge inspectors to manually inspect each bridge every few years. Manpower and budget constraints limit such approach from inspecting the bridges more frequently. Clearly, more efficient approaches need to be developed to improve the process of bridge inspection and increase the overall safety of bridges and civil infrastructures. In this study, we propose a Correlation Network …

Muscle Oxygenation In Patients With Peripheral Artery Disease During Walking With And Without An Ankle Foot Orthosis, Anthony Arellano, Hafizur Rahman, Iraklis Pipinos, Jason Johanning, Sara Myers

UNO Student Research and Creative Activity Fair

Peripheral artery disease (PAD) is a cardiovascular disease caused by blockages in the arteries that reduce blood flow to the peripheral limbs. Claudication, a prominent symptom of PAD is a condition in which the lack of blood flow causes an inability to meet the metabolic demands of the muscle tissue, causes severe cramping pain. Previous studies have shown muscle oxygenation starts significantly lower and declines faster in patients with PAD compared to healthy controls. An ankle foot orthosis (AFO) can provide walking assistance by absorbing and returning the mechanical force during walking. We hypothesized oxygenation levels would be higher in …

An Investigation Of Stimulants: Reviewing Their Effects On The Brain, Including Memory And Microglia, Michael Douchey

UNO Student Research and Creative Activity Fair

Stimulants are a class of drugs that have a variety of effects on the brain, including changes in receptor activity in the brain areas responsible for- memory, attention, emotion, motor control, and the reward pathway. Stimulants may be generally classified by their availability. For example, prescription stimulants, which include drugs such as methylphenidate (Concerta™, Ritalin™) and mixed amphetamine salts (Adderall™), must be prescribed by medical professionals. Another regulated stimulant, albeit one available without a prescription, is nicotine; a highly addictive chemical that is age-restricted by the U.S. federal government. Nicotine is found in tobacco products, and in tobacco-free alternatives including …

Nurses and other medical personnel are frequently victims of what the Department of Labor defines as Type II Violence, or customer-to-employee violence, with 80% of health care workers have reported that they have experienced some type of physical aggression at some point in their career (Clements, DeRanieri, Clark, Manno, Kuhn, 2005). Patient aggression consists of direct physical assaults (with or without weapons), written or verbal threats, physical or verbal harassment, and homicide (Occupational Safety and Health Administration OSHA, 2015). The purpose of this study is to review both organizational factors and personal qualities of medical personnel that influence their responses …

Bimanual Coordination Assessment Using Prosthetic Simulators, Chris Copeland

UNO Student Research and Creative Activity Fair

There were a total of 1.6 million people living with loss of a limb in 2005. This number is projected to double to 3.6 million by 2050 [1]. While prosthetics aim to enhance the function of these individuals, it is estimated that 45% of pediatric prosthetic users reject their prosthesis [2]. The literature which describes the motor control mechanisms of prosthetic use is sparse and often low-powered due to inadequate number of subjects. However, prosthetic simulators may be a solution to chronically low-powered prosthetic studies by serving as functional homologues. The purpose of this investigation was to determine the efficacy …

UNO Student Research and Creative Activity Fair

Bridges in the US scored a C+ on the infrastructure report card in 2017. There is a need for substantial improvement in conditions of these bridges as they are structurally deficient and can become unsafe in the near future. The most recent estimate puts the nation’s backlog of bridge rehabilitation needs at $123 billion. Throughout the country, many state departments of transportation (DOT) have limited resources, leaving them with difficult decisions about where to invest and allocate their limited resources. To make cost-effective decisions, these bridge stakeholders need clean data and studies to estimate the future condition of bridges. This …

A Picture's Worth A Reputation: Visual And Environmental Arguments In Abandoned Disney Park Photographs, Allegra Hardin

UNO Student Research and Creative Activity Fair

This rhetorical criticism analyzes photographs of the Walt Disney Company's abandoned parks, River Country and Discovery Island, taken by Seph Lawless and Shane Perez respectively. Using Foss's (2004) rhetorical focus area of nature, a sample of photographs from Lawless (2016) and Perez's (2009) blogs is analyzed to identify the visual and environmental arguments within the photographs. Noting how these images and the parks themselves are shrouded in obscurity, this essay maintains that the visual and environmental arguments present within the photographs directly challenge the Walt Disney Company's image and calls into question the company's environmental stewardship. This essay contributes to …

Experienced Sexual Assault In The Military: An Exploration Of The Organizational Factors Influencing Under-Reporting And Consequences When Victims Report, Medicine Flower Blue Star

UNO Student Research and Creative Activity Fair

Sexual assault of both male and female service members is a pervasive and serious problem. In 2017, based on data from the U.S. Department of Defense, 5,200 service members reported sexual assault, representing a 10% increase from 2016. Scholars, military and government leaders are concerned that the prevalence of sexual assault is underestimated due to under-reporting. O’Brien, Keith, and Shoemaker (2015), for example, point to a 2013 report by the U.S. Department of Defense, which estimates that 67% of women and 81% of men do not report their military sexual assaults. One purpose of this study is to explore the …

Futurism In Fashion: What Does That Mean?, Jonathan Orozco

UNO Student Research and Creative Activity Fair

In fashion, the term ‘futuristic’ is often used to describe avant-garde clothing designs. It could refer to several things, such as the clothing’s method of production, the materials used, or the garment’s design. Futurism can even refer to the 20^th century Italian art movement, and indeed, this movement addressed the problem of designing fashion for the 20^th century. We would learn much by examining Futurist fashions in order to understand its legacy in relation to contemporary fashion designers viewed as futuristic today. This paper will review this legacy by looking at five specific examples—Italian Futurists and their contribution …

Skin and core temperature were recorded during the 1-hour tolerance trials. Tympanic …

Effects Of Rangeland Management On Milkweed Grazing And Monarch Conservation, Brittany Poynor

UNO Student Research and Creative Activity Fair

Cattle typically avoid consuming milkweed plants that contain high levels of toxic defense compounds, and therefore many people assume cattle avoid all milkweeds. However, common milkweed (Asclepias syriaca) contains only moderate levels of toxic compounds, and observations suggest that cattle regularly consume common milkweed and may even preferentially graze flowers and leaves of this species. These observations directly relate to efforts to add over one billion stems of milkweed to the central USA for monarch butterfly (Danaus plexippus) conservation. If cattle intentionally consume common milkweed and other milkweed species, and if certain management practices can reduce …

Data Analytics Pipeline For Rna Structure Analysis Via Shape, Quinn Nelson

UNO Student Research and Creative Activity Fair

Coxsackievirus B3 (CVB3) is a cardiovirulent enterovirus from the family Picornaviridae. The RNA genome houses an internal ribosome entry site (IRES) in the 5’ untranslated region (5’UTR) that enables cap-independent translation. Ample evidence suggests that the structure of the 5’UTR is a critical element for virulence. We probe RNA structure in solution using base-specific modifying agents such as dimethyl sulfate as well as backbone targeting agents such as N-methylisatoic anhydride used in Selective 2’-Hydroxyl Acylation Analyzed by Primer Extension (SHAPE). We have developed a pipeline that merges and evaluates base-specific and SHAPE data together with statistical analyses that provides confidence …

Marmosets Respond Consistently To Threats Across Contexts, Sarah Carp

UNO Student Research and Creative Activity Fair

Behavioral traits, such as how adventurous an individual is, can vary both across individuals and within an individual across contexts. However, there is evidence that individuals are stable across time in how they respond to certain stimuli. This consistency in behavioral responses to similar environments is termed a behavioral syndrome, or set of correlated behavior. We assessed the degree to which individual marmoset monkeys were consistent across four behavioral tests that measured different aspects of novelty seeking. The four tasks included exposure to a novel object in a familiar environment, exposure to a novel environment, behavioral flexibility in response to …

Early Communicative Characteristics Across Samples From Two Infant Populations At-Risk For Autism, Hannah Lopez, Shari Deveney, Anastasia Kyvelidou

UNO Student Research and Creative Activity Fair

Although no single etiology has been identified for Autism Spectrum Disorders (ASD), two infant populations have emerged as particularly high risk: younger siblings of children diagnosed with ASD and infants born prematurely with low birth weight. A key characteristic differentiating high-risk infants from low-risk peers is early eye gaze fixation behaviors. Early gaze fixation behavior is thought to be predictive of communication and language skills. Consequently, identifying differences in early eye gaze behaviors could lead to early intervention services tailored specifically on counteracting early social withdrawal behaviors. Though few studies have compared eye-gaze patterns of these two high-risk infant groups, …

I Am The Master Of My Fate: How One’S Locus Of Control Influences Entry Type And Level Of Extremist Participation, Steven Windisch

UNO Student Research and Creative Activity Fair

The most pertinent question in terrorism research is not who becomes a terrorist, but who becomes a bomb-maker as opposed to a gunman or a suicide-bomber. To provide a fuller understanding of the mechanisms involved in the process of accepting extremist beliefs, it is essential we embrace a larger view of extremism by linking the psychological antecedents of radicalization with the various types and levels of extremist participation. The current article addresses this issue through an analysis of historiometric data of 261 Salafi Jihadist-inspired extremists in the United States. In doing so, we seek to answer the following question: To …
