Faculty & Staff Scholarship

Background Early pregnancy complaints in emergency medicine are common. Emergency physicians (EP) increasingly employ ultrasound (US) in the evaluation of these complaints. As a result, it is likely that rare and important diagnoses will be encountered. We report a case of fetal anencephaly diagnosed by bedside emergency US in a patient presenting with first-trimester vaginal bleeding.

Case Report A 33-year-old patient at 10 weeks gestation presented with vaginal bleeding. After initial history and physical examination, a bedside US was performed. The EP noted the abnormal appearance of the fetal cranium and anencephaly was suspected. This finding was confirmed by a …

Subject-Specific Biomechanics Of Trunk: Musculoskeletal Scaling, Internal Loads And Intradiscal Pressure Estimation, F. Ghezelbash, A. Shirazi-Adl, N. Arjmand, Z. El-Ouaaid, A. Plamondon

Études primaires

Development of a subject-specific computational musculoskeletal trunk model (accounting for age, sex, body weight and body height), estimation of muscle forces and internal loads as well as subsequent validation by comparison with measured intradiscal pressure in various lifting tasks are novel, important and challenging. The objective of the present study is twofold. First, it aims to update and personalize the passive and active structures in an existing musculoskeletal kinematics-driven finite element model. The scaling scheme used an existing imaging database and biomechanical principles to adjust muscle geometries/cross-sectional-areas and passive joint geometry/properties in accordance with subjects’ sex, age, body weight and …

Mapping Forest Health Using Spectral And Textural Information Extracted From Spot-5 Satellite Images, Jinghui Meng, Shiming Li, Wei Wang, Qingwang Liu, Shiqin Xie, Wu Ma

Faculty & Staff Scholarship

Forest health is an important variable that we need to monitor for forest management decision making. However, forest health is difficult to assess and monitor based merely on forest field surveys. In the present study, we first derived a comprehensive forest health indicator using 15 forest stand attributes extracted from forest inventory plots. Second, Pearson’s correlation analysis was performed to investigate the relationship between the forest health indicator and the spectral and textural measures extracted from SPOT-5 images. Third, all-subsets regression was performed to build the predictive model by including the statistically significant image-derived measures as independent variables. Finally, the …

Automated Classification Of Vowel Category And Speaker Type In The High-Frequency Spectrum, Jeremy J. Donai, Saeid Motiian, Gianfranco Doretto

Faculty & Staff Scholarship

The high-frequency region of vowel signals (above the third formant or F3) has received little research attention. Recent evidence, however, has documented the perceptual utility of high-frequency information in the speech signal above the traditional frequency bandwidth known to contain important cues for speech and speaker recognition. The purpose of this study was to determine if high-pass filtered vowels could be separated by vowel category and speaker type in a supervised learning framework. Mel frequency cepstral coefficients (MFCCs) were extracted from productions of six vowel categories produced by two male, two female, and two child speakers. Results revealed that the …

Microtubule Modification Influences Cellular Response To Amyloid-Β Exposure, Nicole Shamitko-Klingensmith, Jonathan W. Boyd, Justin Legleiter

Faculty & Staff Scholarship

During the normal aging process, cytoskeletal changes such as a reduction in density or disruption of cytoskeletal components occur that can affect neuronal function. As aging is the biggest risk factor for Alzheimer's disease (AD), this study sought to determine how microtubule (MT) modification influences cellular response upon exposure to β-amyloid1-42 (Aβ1-42), which is implicated in AD. The MT networks of hypothalamic GT1-7 neurons were modified by common disrupting or stabilizing drugs, and then the physical and mechanical properties of the modified neurons were determined. The MT modified neurons were then exposed to Aβ1-42 and the ability of the neurons …

The rise of neoliberalism is creating inequalities for women as they balance their private lives and career trajectories. Geography as a middle sized discipline bridging the social and physical sciences offers insights into the ways neoliberal policies are felt by early career women (ECW). Using a life course model, this study presents the results of a workshop which sought to explore the ways in which women geographers, in Sweden, perceive and experience obstacles in their career advancement and which coping strategies they put in place to overcome those. The results show the blurring of the ECW ́s work and private …

Effect Of Spatial Inhomogeneities On The Membrane Surface On Receptor Dimerization And Signal Initiation, Romica Kerketta, Adam M. Halasz, Mara P. Steinkamp, Bridget S. Wilson, Jeremy S. Edwards

Faculty & Staff Scholarship

Important signal transduction pathways originate on the plasma membrane, where microdomains may transiently entrap diffusing receptors. This results in a non-random distribution of receptors even in the resting state, which can be visualized as “clusters” by high resolution imaging methods. Here, we explore how spatial in-homogeneities in the plasma membrane might influence the dimerization and phosphorylation status of ErbB2 and ErbB3, two receptor tyrosine kinases that preferentially heterodimerize and are often co-expressed in cancer. This theoretical study is based upon spatial stochastic simulations of the two-dimensional membrane landscape, where variables include differential distributions and overlap of transient confinement zones (“domains”) …

Many intervention methods have been researched and implemented to assist in communication and social involvement for children with ASD. However, little research exists on helping young children with ASD effectively transition, both academically and socially, from one educational environment to another. This research will contain a case study of a six-year-old child enrolled …

Real-Time Monitoring Of Personal Exposures To Carbon Dioxide, Elliott T. Gall, Toby Cheung, Irvan Luhung, Stefano Schiavon, William W. Nazaroff

Mechanical and Materials Engineering Faculty Publications and Presentations

Elevated indoor CO₂ levels are indicative of insufficient ventilation in occupied spaces and correlate with elevated concentrations of pollutants of indoor origin. Adverse health and well-being outcomes associated with elevated indoor CO₂ levels are based on CO₂ as a proxy, although some emerging evidence suggests CO₂ itself may impact human cognition. Using portable monitors, we conducted an exposure study with 16 subjects in Singapore to understand the levels, dynamics and influencing factors of personal exposure to CO₂. Participants carried a CO₂ monitor continuously for 7-day periods recording their exposure levels at 1-min intervals. …

Analyzing The Growing Islamic Radicalization In France, Virginia Ruth Brommer

Honors Theses

Islamic radicalization in European countries is becoming more and more prevalent, as evidenced by the number of recent attacks by Muslims in Europe. I argue that the social, religious, and psychological environment in France creates a unique opportunity for Islamic radicalization, particularly through social media and in prisons. After defining radicalization and explaining two radicalization processes as well as different types of radicals, I analyze the specific factors present in France that contribute to this radicalization. I use case study analysis to examine several French citizens who radicalized, either online or in prison, in order to show how the recruiter …

Identification Of Inhibitors Of Fxii, Alexandra C. Bensel

Honors Theses

Hereditary angioedema is characterized by recurrent swelling of the extremities, larynx, and gastrointestinal tract. While type I and type II hereditary angioedema result from a C1-inhibitor deficiency, a new variant of the disease, type III hereditary angioedema, was recently discovered in individuals with functioning levels of the C1-inhibitor. Ongoing research has postulated that increased activity of factor XII is responsible for this new form of hereditary angioedema because it causes overproduction of bradykinin. The purpose of the experiment was to identify inhibitors of factor XII. One hundred and seventy six molecules were screened through a dose response using Human Factor …

This Clinic Stays Open: A Comprehensive History Of Reproductive Rights In Mississippi, 1966-2015., Alicia Bacon

Honors Theses

In 1966, Mississippi became the first state to reform its criminal abortion laws when it legalized abortion in the case of rape. From the Roe v. Wade decision of 1973 to 1986, Mississippi experienced a rapid and dramatic expansion of abortion services and the practice remained relatively unrestricted. Today, Mississippi boasts some of the most restrictive abortion laws in the nation and only one clinic remains open in the state. Through analysis of newspaper clippings, legislative documents, court rulings, and statistical analyses, this thesis discerns how and when reproductive rights came to be so threatened in Mississippi. The findings show …

The Technician Behind The Artist: Where Science Meets Art, Joella Vaughnn

Honors Theses

The thesis has two purposes: to evaluate the difference between oil, acrylic, gouache, and encaustic paint for the purpose of glazing and to integrate engineering and artistic principles into this thesis. My final evaluation across the four paints is that oil has the highest performing glaze. I believe it is the best glazer because time is not a constraint for me as an artist. If an artist has a time constraint on their painting, I recommend using acrylic mixed with an acrylic polymer medium as a glaze because the drying time is much faster than oil. I discovered that gouache …

Design And Synthesis Of Dual Opioids/Npff Ligands As Novel Analgesics With Reduced Tolerance Potential, John N. Yi

Honors Theses

Opioid use has become prevalent in today's culture. As a treatment for acute and chronic pain, opioids permeate in the public sphere as a seemingly easy solution. However, problems that come from the increased use of opiates, especially in the last fifteen years, have shown detrimental effects in society. Not only are all opioid-based analgesics considered addictive, but the nature of such painkillers also enables a phenomenon known as tolerance, where the body adapts to the use of exogenous opioids. This creates a situation where a more potent dose of painkiller is required for the same analgesic effect. The focus …

An Examination Of The College Major Decisions Of Students At The University Of Mississippi, Jonathan P. Evans

Honors Theses

Factors such as socio-economic status affect students' level of educational aspiration. Furthermore, major (and thus career choice) may be influenced by race or gender. This study demonstrates the effects of academic aptitude, race, gender, first generation status, and importance of expected future earnings on undergraduate students' college major decision. More specifically, this study examines if these factors lead to an increase or decrease in the probability of students choosing a major in a specific field. The likelihood of choosing a major in a specific field is relative a baseline category, which can be changed.

Wastewater Treatment Plants: A Comparison Of Three Different Plants And Their Processes, Facilities, And Challenges They Face, Jon Abigail Mcdonald

Honors Theses

This study compared methods of wastewater treatment, and the conditions that they must be able to accommodate. To address this issue I visited wastewater treatment plants in three locations: Clarksdale, MS; University of Mississippi; and Oxford, MS. Additionally, I examined the chemistry and microbiology of the water in their respective receiving streams. I hypothesized that the wastewater plant with the most modern facilities and resources available would have the least effect on the water quality of its receiving stream. At each plant I learned what chemicals, equipment, and other methods are used, as well as unique challenges their treatment systems …
