Exploration Of The Relationship Between The Mean Power Spectral Density Of Electrogastrography And Gestational Maturation Of Preterm Infants, Elizabeth Ann Rhodes

2023 Spring Honors Capstone Projects - Archive

Feeding preterm infants can be a challenge due to gastrointestinal (GI) immaturity which can lead to feeding intolerance, malnutrition, and poor neurodevelopment. Currently there is no non-invasive and quantitative method to determine GI maturity in infants. Electrogastrography (EGG) provides a non-invasive method of measuring gastric myoelectrical activity and has been used on adults to determine gastric abnormalities. EGG was explored as an option for determining GI maturity in preterm infants by quantifying the power spectral density (PSD) of EGG data and its spectral means. The power spectral density and spectral means were calculated during three gastric rhythm (GR) bands (mPSDgr) …

Parthenogenesis Investigation Of The F1 Generation From A Cross Between Daphnia Pulex Tex 23 (Males) And Tex 85 (Females), Efe Amrovhe

2023 Spring Honors Capstone Projects - Archive

Daphnia pulex is a species of Daphnia that is capable of both cyclic and obligate parthenogenesis. In this experiment, two cyclically parthenogenetic (CP) isolates are crossed to access the frequency of obligately parthenogenetic (OP) offspring that will be produced. If OP animals are produced at a significant frequency from a CP-CP cross, the ‘why’ behind it must be examined. Prior research revealed that OP animals produced from CP isolates are genetically linked through introgression from a sister species, Daphnia pulicaria. This may be relevant to the results and serve as a focal point when researching the implications of them. The …

Life History Fitness Of F1 Hybrids Of Tex & Pa21 Populations Of Daphnia Pulex, Ohitha Reddy Sana May 2023

Life History Fitness Of F1 Hybrids Of Tex & Pa21 Populations Of Daphnia Pulex, Ohitha Reddy Sana

2023 Spring Honors Capstone Projects - Archive

Evolutionary theory suggests that fitness decreases with hybridization as a result of negative epistatic interactions between alleles that rose independently in genetic backgrounds making hybrids incompatible with parents’ species. However, heterosis can occur as a result of the deleterious effects of negative epistatic interactions making hybrids fitter than their parents. To examine this, the fitness of first-generation (F1) hybrids of Tex and PA populations of Daphnia pulex was determined using body size as a life history trait. F1 hybrids obtained from crossing between seven Tex parental isolates and PA parental isolates were taken from stock and grown under standard conditions …

Creating Tools To Investigate The Predictive Power Of Polygenic Score For The Big 5 Personality Traits And Math Ability, Roman Goff

2023 Spring Honors Capstone Projects - Archive

Studies have shown that personality and mathematical ability are heritable traits. In the past, the genetic component of this heritability was investigated using twin studies where genetically identical twins are reared apart and the siblings’ traits are compared. Genome-wide association studies (GWAS) have obviated the necessity of such methods by combining genetic data with modern computing power. The exponential decrease in cost of human genome sequencing and increase in accessibility has made it trivial to use an individual’s alleles to correlate their genome to their phenotypic traits. In this study, the results of a GWAS for the Big Five personality …

Spelunking Through A Forest Of Roots: Solutions Of Polynomials In Different Number Systems, Nathan Easley

2023 Spring Honors Capstone Projects - Archive

Most advanced college students are familiar with the fact that an equation p(x) = 0, where p(x) is a polynomial of degree n with real coefficients, will have at most n solutions. When the coefficients are complex, the Fundamental Theorem of Algebra (FTA) says that there are exactly n solutions, counting multiplicity. For example, x^3 - x = 0 has exactly three solutions, 0, 1, and -1. This thesis investigates how many solutions polynomial equations have in other number systems, particularly in hyperbolic and parabolic numbers. Our methods involve looking for how many solutions simple equations, such as x^2 - …

Batson V. Kentucky Guidelines And The Use Of Peremptory Challenges In Arkansas Courts: A Case Study, Abigail Lindsey

Political Science Undergraduate Honors Theses

The peremptory challenge is a method by which attorneys can strike a potential juror from the jury pool without a valid reason. With Batson v. Kentucky (1986), the Supreme Court ruled that peremptory challenges cannot be issued on the basis of race, however, there are many problems with the way this precedent has been followed in various states. The goal of this research is to analyze how Arkansas courts implement the Batson precedent. This research also studies whether the way in which Arkansas courts utilize the peremptory challenge creates ideologically imbalanced juries.

Novel Roles Of Standard And Non-Standard Null Lagrangians In Classical And Quantum Physics, Lesley Catherine Vestal May 2023

Novel Roles Of Standard And Non-Standard Null Lagrangians In Classical And Quantum Physics, Lesley Catherine Vestal

Physics Dissertations - Archive

The three known families of Lagrangians are standard, non-standard, and null Lagrangians. While Lagrangians are widely used in Physics for their ability to characterize physical systems, most of this work uses only standard Lagrangians. As such, standard Lagrangians have been studied in Physics for around three hundred years; however, non-standard Lagrangians for systems in Physics have been considered only for a few decades, and null have been ignored almost entirely. Although only some Lagrangians are null Lagrangians, all Lagrangians can be categorized as either standard or non-standard Lagrangians, meaning that there exist standard null Lagrangians and non-standard null Lagrangians.

Model And Observation Comparisons Of Ionospheric Current Systems, Tre'shunda James May 2023

Model And Observation Comparisons Of Ionospheric Current Systems, Tre'shunda James

Physics Dissertations - Archive

The interaction between the dynamically changing solar wind and Earth’s magnetosphere results in several different current systems. The most relevant to space weather are the Birkeland currents, a.k.a field-aligned currents (FACs), that couple the magnetosphere to the ionosphere. These currents flow into and out of the ionosphere and are closed through the ionosphere by the horizontally flowing eastward and westward electrojets. This FAC-electrojet current system is responsible for some of the most beautiful and detrimental space weather impacts. The aurora borealis (or northern lights) in the Northern Hemisphere and aurora australis (or southern lights) in the Southern Hemisphere are displays …

Exploring Numerical Simulations Of Localized Geomagnetic Disturbances, Elizabeth Vandegriff May 2023

Exploring Numerical Simulations Of Localized Geomagnetic Disturbances, Elizabeth Vandegriff

Physics Dissertations - Archive

One of the prominent effects of space weather is the formation of rapid geomagnetic field variations on Earth’s surface driven by the magnetosphere-ionosphere system. These Geomagnetic Disturbances (GMDs) cause Geomagnetically Induced Currents (GICs) to run through ground-conducting systems. GMDs can often be high amplitude and small-scale (100-500 kilometers) and we classify these as Localized GMDs (LGMDs). LGMDs are both hazardous to the power grid and difficult to predict. Modeling LGMDs is therefore a critical step for risk mitigation but is complicated due to the dynamic and sometimes highly localized nature of the phenomena. At present, global magnetohydrodynamic (MHD) models of …
