Evaluating The Nutritional Adequacy Of Peruvian-American Children, Delainey Dietz

Honors Undergraduate Theses

As people move and integrate cultures, nutritional trends may change from those of their native country to those of their new country. With today's increasing global immigration, studies have only scratched the surface of the impact of acculturation on children's health and nutrition. Specifically, the Peruvian-American diet is one that has garnered minimal research. The purpose of this study is to evaluate the common foods and drinks that Peruvian-American children consume, assess the children's physical health, and discuss the possible causative factors of any diet trends. The population sampled is children under 18 years living in the United States whose …

Effects Of Resin Chemistries On The Selective Removal Of Industrially Relevant Metal Ions Using Wafer-Enhanced Electrodeionization, Humeyra B. Ulusoy Erol, Christa N. Hestekin, Jamie A. Hestekin

Chemical Engineering Faculty Publications and Presentations

Wafer-enhanced electrodeionization (WE-EDI) is an electrically driven separations technology that occurs under the influence of an applied electric field and heavily depends on ion exchange resin chemistry. Unlike filtration processes, WE-EDI can be used to selectively remove ions even from high concentration systems. Because every excess ion transported increases the operating costs, the selective separation offered by WE-EDI can provide a more energy-efficient and cost-effective process, especially for highly concentrated salt solutions. This work reports the performance comparison of four commonly used cation exchange resins (Amberlite IR120 Na⁺, Amberlite IRP 69, Dowex MAC 3 H⁺, and …

Black Women's Suffrage, The Nineteenth Amendment, And The Duality Of A Movement, Danielle M. Conway

Faculty Scholarly Works

America is at an unprecedented time with self-determination for Black women, and this phase of the movement is reverberating throughout this nation and around the world. There is no confusion for those who identify as Black women that this movement is perpetual, dating back to the enslavement of Black people in America by act and by law. One need only look to the intersecting crises of 2020 to discern the reality of Black women’s—and by extension the Black community and by further extension individuals and groups marginalized, subordinated, and oppressed by white patriarchy—perpetual struggle for civil and human rights.

Nanoporous Gold Monolith For High Loading Of Unmodified Doxorubicin And Sustained Co-Release Of Doxorubicin-Rapamycin, Jay Bhattarai, Dharmendra Neupane, Bishal Nepal, Alexei Demchenko, Keith Stine

Chemistry & Biochemistry Faculty Works

Nanoparticles (NPs) have been widely explored for delivering doxorubicin (DOX), an anticancer drug, to minimize cardiotoxicity. However, their efficiency is marred by a necessity to chemically modify DOX, NPs, or both and low deposition of the administered NPs on tumors. Therefore, alternative strategies should be developed to improve therapeutic efficacy and decrease toxicity. Here we report the possibility of employing a monolithic nanoporous gold (np-Au) rod as an implant for delivering DOX. The np-Au has very high DOX encapsulation efficiency (>98%) with maximum loading of 93.4 mg cm−3 without any chemical modification required of DOX or np-Au. We provide …

Qualitative Prediction Of Ligand Dissociation Kinetics From Focal Adhesion Kinase Using Steered Molecular Dynamics, Justin Spiriti, Chung Wong

Chemistry & Biochemistry Faculty Works

Most early-stage drug discovery projects focus on equilibrium binding affinity to the target alongside selectivity and other pharmaceutical properties. Since many approved drugs have nonequilibrium binding characteristics, there has been increasing interest in optimizing binding kinetics early in the drug discovery process. As focal adhesion kinase (FAK) is an important drug target, we examine whether steered molecular dynamics (SMD) can be useful for identifying drug candidates with the desired drug-binding kinetics. In simulating the dissociation of 14 ligands from FAK, we find an empirical power–law relationship between the simulated time needed for ligand unbinding and the experimental rate constant for …

Popular Methods Of Biological Control And The Future Of Baculoviruses, Michael Hutchinson

Undergraduate Review

Biological control is a pest management strategy with the goal of reducing pest populations through human collaboration. Methods of biological control used to combat pests involve the physical removal of organisms and the application of predators, parasitoids, chemical insecticides, microbes, and viruses. However, many methods of biocontrol have proven to become ineffective overtime due to target organism adaptability taking place as a part of the natural process of evolution. As a result of previously failed attempts of utilizing different forms of biocontrol, the application of viruses as an alternative is in consideration by scientists to control pest populations. Application of …

Vertex-Magic Graphs, Karissa L. Massud

Undergraduate Review

In graph theory, a graph labeling is an assignment of labels to the edges and vertices of a graph. There are many different types of graphs labelings. Some include graceful labelings, harmonious labelings, and magic labelings. In this project we will focus on a type of magic labeling. A vertex-magic total labeling is a labeling such that the vertices and edges are assigned consecutive integers between 1 and v+e, where v is the order of the graph and e is the size of the graph. When the sum of the labels of a vertex and its incident edges results in …

Democratic Disenfranchisement: Analyzing The Factors That Contribute To Or Hinder The Ability Of Marginalized Groups To Run For Public Office In Kentucky, Isaac Keller

Mahurin Honors College Capstone Experience/Thesis Projects

Much has been written about barriers that lead to unequal representation, focusing largely on situational characteristics of the individual voter (socioeconomic status, efficacy, socialization, etc.) and on structural (institutional) obstacles to voter turnout and participation. However, political participation is inclusive of more than just voting. This research seeks to identify and analyze the factors that contribute to or hinder the ability of marginalized candidates to run for public office. To explore whether or not marginalized candidates face unique obstacles when running for public office, a qualitative approach with one-on-one interviews between a convenience sampling in Kentucky of ten political candidates …

Dung Beetle (Scarabaeinae) Diversity Of The Highest Elevation In West Africa: The Nimba Mountain Range, Jacob Bowen

Mahurin Honors College Capstone Experience/Thesis Projects

The Nimba Mountain Range in Guinea, Ivory Coast, and Liberia is within the Upper Guinean Forests, a critical biodiversity hotspot highly threatened by various human activities. The region is home to many endemic species including the viviparous Nimba toad, Nimba otter-shrew, and the discrete Bossou chimpanzee population. Dung beetles can act as a focal taxon from which extrapolation to the diversity of other taxa and ecosystem health can be made. Elevational trends in dung beetle diversity were investigated on the Nimba Mountain Range and in the nearby Bossou Chimpanzee reserve in Guinea. Dung beetle species diversity surveys aimed to document …

Acoustic Communication In The Atlantic Mudskipper, Periopthalmus Barbarus, Seth Hoffman

Mahurin Honors College Capstone Experience/Thesis Projects

Mudskippers are intertidal fishes that can survive both in and out of the water. They are territorial and exhibit behaviors to attract mates and defend against competitors. Recently, it has been shown that vibrations are produced and transmitted through the mud during such displays in one species, Periophthalmodon septemradiatus. To see if similar vibrations are produced in other species of mudskippers, I recorded the behavioral interactions of pairs of the mudskipper Periophthalmus barbarus via digital video and acoustic signals via accelerometer. Comparative analysis of fish mass, sex, contest length, and contest outcome coupled with acoustic characteristics within dyadic pairings …

A Comparison Of Bee Abundance And Species Richness In Three Managed Grassland Types, Emily Russ

Mahurin Honors College Capstone Experience/Thesis Projects

Bees are threatened by environmental changes, pathogens, and pesticides (Pettis, 2012, Meeus et al., 2018). The goal of the study is to compare and evaluate the bee abundance and species richness in three different field types. My hypothesis is that bees would favor the fields planted for their benefit, and that the tall grass dominated plantings would be preferred over mowed fescue. My findings have low power considering few replicates and the use of relative abundance and relative species richness for statistical analyses. Bee abundance and species richness had an overall positive relationship of varying degrees across habitat types. Relative …

Judges, Attorneys, And Psychologists' Views Of Sole-Parent Child Custody Evaluations, Chandler Flynt

Mahurin Honors College Capstone Experience/Thesis Projects

Judges, attorneys, and psychologists are individuals in the legal system who have the most interaction with child custody evaluations (CCEs), yet there is little research regarding whether these parties have different views on what factors are important in CCEs. The present study examined how judges, attorneys, and psychologists evaluated sole-parent child custody cases. A sample of judges, attorneys, and psychologists completed a forty-item questionnaire regarding their opinions of what factors they believe are most/least important in CCEs. The goal of this study was to first observe if there were differences among the parties’ ratings, and secondly, determine why might differences …

Development Of A Dna Biosensor Using Crispr/Dcas9 On A Graphene Oxide Surface For Detecting Antibiotic Resistance Genes, Wendy Cecil

Mahurin Honors College Capstone Experience/Thesis Projects

Antibiotic resistance is a rapidly spreading global threat to human health. Previously in our lab, we developed a simple method for facile detection of antibiotic resistance genes (ARGs) in bacteria. This DNA detection system takes advantage of the CRISPR-Cas system (Clustered Regularly Interspaced Short Palindromic Repeat and CRISPRAssociated Protein). We designed CRISPR in complex with nuclease deactivated Cas9 (dCas9) on graphene oxide (GO) sheets conjugated with Cas9 antibodies. Single guide RNA (sgRNA) was customized to program dCas9 for target DNA binding. sgRNA was covalently labeled with fluorescein to provide fluorescence signal. Graphene oxide (GO) is utilized for its quenching properties …

Antibiotic Resistant Gene Concentrations In Bacteria In Groundwater From Agricultural Waste, Koji Barnaby

Mahurin Honors College Capstone Experience/Thesis Projects

The overuse of antibiotics has led to an increase in antibiotic resistant bacteria since some antibiotics are sent into the wastewater system by waste produced by both humans and agriculture, making exposure to these bacteria more likely. The evolution of these bacteria in groundwater is of particular concern, as groundwater is used as a source of drinking water, and infections by these bacteria would be more difficult to treat. There are no policies in place to monitor or regulate antibiotic resistance bacteria in groundwater, leaving the threat to public health unknown. The study area of Crumps Cave in Smiths Grove, …

Soil Research Project, Kate Donaldson

Natural Sciences Student Research Presentations

My topic is how earthworms interact with soil. Most people learn from an early age that earthworms are an important part of soil and plant life, but many do not know the actual reasoning and evidence behind it. My audience would be interested in this topic because it is interesting to expand knowledge on things already considered well know. While many earthworms are not endangered, we still need to be carful and protect the animal that is vital to plant growth and soil health.

Residue From Sequestrene 138 Fe Eddha Clogs Filters: Alternatives For Chelated Iron In Liquid Fertilizer Systems, Brendan Fatzinger, Bruce Bugbee

Nutrients

Ferric iron rapidly precipitates as FeOH and becomes biologically unavailable, so chelated iron is commonly used in liquid fertilization systems to keep it in solution. The most common chelating agents in agriculture are:

• EDDHA (ethylenediamine-N,N'-bis(2-hydroxyphenylacetic acid)
• DTPA (diethylenetriaminepentaacetic acid)
• EDTA (ethylenediaminetetraacetic acid)
• and for monocots in deep-flow hydroponics, HEDTA (also called HEEDTA)

Effect Of Acute Sleep Fragmentation Upon Inflammatory Response Of Brown And White Adipose Tissue In Male Mice, Zach Wriedt

Mahurin Honors College Capstone Experience/Thesis Projects

Sleep is an important process required for vertebrates, including humans, to function. When sleep is disrupted, it leads to deleterious effects such as inflammatory responses throughout the body. Past studies have shown that acute (24 h) sleep fragmentation (SF) leads to an inflammatory response in white adipose tissue. However, whether brown adipose tissue responds in a similar fashion is unknown. Male adult (>8 weeks of age) C57BL/6j mice were subjected to SF for 24 h using a cage outfitted with a bar that moves horizontally across the cage every 2 min to periodically awaken mice (N =10). Controls were …
