Quantitative Non-Destructive Evaluation Of Rebar Corrosion In Concrete, Khadiza Binte Jalal

Civil Engineering Dissertations - Archive

ABSTRACT: Corrosion of rebar is considered the leading cause of deterioration in concrete structures. When steel rust, it occupies larger volume and creates pressure on the concrete, leading to cracking and spalling. As the cross-section is being compromised, the structural capacity of the reinforced concrete structure is reduced. Corrosion is a slow natural electrochemical process that affects the long-term performance. However, sometimes premature catastrophic failure occurs due to corrosion, especially in chloride environments. Moreover, the cost of repair and replacement of deteriorated structures has become a major liability for management agencies. Consequently, it is important to determine the level of …

Reactive Thin Film Polymers And Thin Film Composite Membranes For The Rapid Screening Of Uranium Isotopes, Abenazer W. Darge

All Dissertations

Traditional radiochemistry approaches for the detection of trace-level alpha-emitting radioisotopes in water require lengthy offsite sample preparations and do not lend themselves to rapid quantification. Therefore, a novel platform is needed that combines onsite purification, concentration, and isotopic screening with a fieldable detection system. My dissertation research objective was to develop novel reactive thin polymer films and thin film composite membranes for the selective separation of uranium from environmental water followed by direct isotopic analysis by alpha spectroscopy. Chapter 1 reviews progress made on uranium separation from aqueous matrices and discusses methods used for the determination of isotopic composition.

An Investigation Into The Roles Of Aldose Reductase And Acetate Kinase In The Metabolism Of Entamoeba Histolytica, Matthew B. Angel

All Dissertations

Entamoeba histolytica is an amoebic parasite that infects an estimated 90 million people worldwide and causes approximately 100,000 deaths per year. As the causative agent of amoebic dysentery, this food- and water-borne pathogen represents a significant public health burden worldwide, particularly in areas with poor sanitation. While treatments for amoebiasis exist, they are often limited in their effectiveness. Thus, efforts to better understand the biology and physiology of this organism are vital to the development of novel treatments for this disease.

E. histolytica lacks the enzymes for many common metabolic pathways such as the citric acid cycle and oxidative phosphorylation …

Suppression Of Microrna 124–3p And Microrna 340–5p Ameliorates Retinoic Acid-Induced Cleft Palate In Mice, Hiroki Yoshioka, Akiko Suzuki, Chihiro Iwaya, Junichi Iwata

Faculty, Staff and Student Publications

The etiology of cleft lip with or without cleft palate (CL/P), a common congenital birth defect, is complex, with genetic and epigenetic, as well as environmental, contributing factors. Recent studies suggest that fetal development is affected by maternal conditions through microRNAs (miRNAs), a group of short noncoding RNAs. Here, we show that miR-129-5p and miR-340-5p suppress cell proliferation in both primary mouse embryonic palatal mesenchymal cells and O9-1 cells, a neural crest cell line, through the regulation of Sox5 and Trp53 by miR-129-5p, and the regulation of Chd7, Fign and Tgfbr1 by miR-340-5p. Notably, miR-340-5p, but not miR-129-5p, was upregulated …

Engineering Management and Systems Engineering Faculty Research & Creative Works

PURPOSEDisparities in radiation oncology (RO) can be attributed to geographic location, socioeconomic status, race, sex, and other societal factors. One potential solution is to implement a fully mobile (FM) RO system to bring radiotherapy to rural areas and reduce barriers to access. We use Monte Carlo simulation to quantify techno-economic feasibility with uncertainty, using two rural Missouri scenarios.METHODSRecently, a semimobile RO system has been developed by building an o-ring linear accelerator (linac) into a mobile coach that is used for temporary care, months at a time. Transitioning to a more FM-RO system, which changes location within a given day, presents …

Determination Of Tissue-Level Changes In Tumors That Are Indicative Of Metastasis Using Optical Spectroscopy, Sanidhya D. Tripathi

Biomedical Engineering Undergraduate Honors Theses

Breast cancer, accounting for 12% of all new cancer cases, is one of the leading causes of death in women worldwide. Although patient survival has improved over the years, metastatic spread to other organ sites and not due to the primary tumor is the most common form of tumor recurrence, accounting for 90% deaths. Hypoxia is a common hallmark of solid tumors and is linked with metastasis, therapeutic resistance, and poor patient survival. Defined as a state of decreased oxygen availability, cells under hypoxia have an increased rate of genetic mutation, local invasion, and resistance to treatment such as radiation …

Bioelectrics Publications

In this work, we report a wafer-scale and chemical-free fabrication of nickel (Ni) and copper (Cu) heteroatomic Cu–Ni thin films using RF magnetron sputtering technique for non-enzymatic glucose sensing application. The as-prepared wafer-scale Cu–Ni thin films exhibits excellent electrocatalytic activity toward glucose oxidation with a 1.86 μM detection limit in the range of 0.01 mM to 20 mM range. The Cu–Ni film shows 1.3- and 5.4-times higher glucose oxidation activity in comparison to the Cu and Ni electrodes, respectively. The improved electrocatalytic activity is attributed to the synergistic effect of the bimetallic catalyst and high density of grain boundaries. The …

Corruption In Uganda, Jared Saxton

Ballard Brief

Corruption in Uganda accounts for ½ of government expenditure and mainly benefits the rich and well connected. Due to weak and unspecific laws, corruption is often not enforced in the nation. Additionally, when there are adequate laws in place, enforcement agencies often benefit from corruption and are therefore unmotivated to take action against it. Cultural factors mean that corruption is socially acceptable in many cases and is common throughout the nation. Foreign aid props up corrupt government expenditure because funding comes from an external source, and thus, the government feels less accountable to its citizens. Corruption results in poor service …

Inadequate Wash Infrastructure Among Rural Populations In The Pacific Islands, Olivia Wallgreen

Ballard Brief

Water, Sanitation, and Hygiene (WASH) are key aspects for development that allows families to five clean and healthy lives. However. many regions of the world. including the Pacific Islands Region. do not have proper facilities and funding to build or maintain WASH infrastructure. especially in rural areas. About 45% of rural Pacific Islanders lack access to adequate sanitation and 13% lack access to basic drinking water. Natural disasters. climate change, insufficient government action. and difficult geographic features make developing WASH infrastructure challenging. Inadequate WASH infrastructure increases the prevalence of disease and negatively affects the ecosystems of the islands. While these …

Inadequate Maternal Health Care For Women In The United States, Rebecca Stull Zundel

Ballard Brief

Although insufficient maternal health care has seen improvements in most developed countries, it is still a rising issue in the United States. This insufficiency may partly be due to the accessibility barriers that both rural and urban women face in reaching adequate care. Additionally, the expenses of maternal care or gender discrimination within medical establishments may dissuade women from seeking the care that they need. Women who receive inadequate care are at a higher risk for maternal mortality, the death of their unborn or newly born infant, and having a low-birth weight child, which comes with many issues of its …

Budesonide Embedded Sodium Alginate Thin Films For Controlled Release To The Esophagus, Norah Almahbub, Jacob Vandervaart, Rachel Chevalier

Research at Children's Mercy Month 2022

BACKGROUND: Eosinophilic esophagitis (EoE) is an allergic inflammatory disease affecting children at an increasing rate leading to poor weight gain, vomiting, esophageal strictures and increased health care burden from repeated endoscopies. Oral budesonide is the only drug commercially available for treatment, but adverse effects and compliance limit its utility.

We seek to design a microscale, low-aspect ratio, biodegradable, dispersible form of budesonide with controlled release. Our first step is to fabricate thin films utilizing common mucoadhesive polymers (chitosan and sodium alginate) embedded with budesonide. Here we report on the release characteristics of these thin films.

METHODS: Budesonide is suspended in …

Characteristics Of Hospitalized Children Associated With Restraint Use At A Free-Standing Children’S Hospital, Adrienne Deporre, Vincent S. Staggs, Ingrid Larson, Ashley Daly, Cy Nadler

Research at Children's Mercy Month 2022

Introduction:Hospitalized children are at risk for agitation and behavioral dysregulation, which may escalate to unsafe behaviors. If less restrictive de-escalation strategies fail to mitigate serious safety risks to self or others, mechanical restraints may be used on a limited basis. Restraint use, however, is problematic due to associated negative child mental health outcomes and injury risk. Pediatric studies of restraint use outside of dedicated psychiatric facilities are lacking. Specifically, clinical and demographic features associated with restraint use are poorly described. A broader understanding of restraint use among hospitalized children can guide alternative strategies for management and restraint mitigation efforts. …

The Cellular Dynamics Of Early And Transitional Human Breast Milk, Cas Lemaster, Stephen Pierce, Eric S. Geanes, Santosh Khanal, Staci Elliott, Allison Scott, Daniel A. Louiselle, Rebecca Mclennan, William E. Truog, Devika Maulik, Tamorah Lewis, Tomi Pastinen, Todd Bradley

Research at Children's Mercy Month 2022

Breast milk (BM) is a complex fluid containing factors essential for infant nutrition and immunity. Breastfeeding has been shown to be protective against infections and other immune-mediated diseases during the lacation period and beyond in later childhood. This suggests that BM also imprints the neonatal immune system and influences long-term health. BM also contains populations of maternal-derived cells. Which factors in BM that are important for neonatal health and how they change during lactation have not been well-defined. In this study, we used a single-cell transcriptomic approach to identify and define cell types of early and transitional milk. We collected …

Female Students’ Perception Of Stem Identity At Utrgv, Kristen L. Hallas

Honors Theses

Despite the increase in representation of women in science, technology, engineering, and mathematics (STEM) undergraduate programs, they are still underrepresented in the workforce. Recent statistics published by the National Science Foundation show that the rate of females and Hispanic/Latina females earning degrees does not match the rate in which they earn STEM occupations, especially advanced degrees. Moreover, out of early career doctorate holders, women are less likely to hold post-doctoral scholar positions and are more likely to hold an academic, non-tenure track position. In response to these disparities, I sought to identify the strongest motivators driving the ambition of female …

The prediction is to predict around 3000 SKUs in 19 end markets and since the data is necessary for marketing enhancement and strategies, the Forecasting accuracy must be high. Since market strategies will be based on those predictions and revenue will be lost in the case of an error. Hence, we need to keep in mind that the model is not overfitted and that it …

How Will God And The Church Fit Into The Metaverse?, Grace Rose

Comm-entary

In this paper, I tell a story about the argument over whether God and the Church will be part of our coming “metaverse.” While we can be pretty sure that the metaverse will be good for the full range of “congregations,” good, reasonable citizens disagree about whether the metaverse will be just a tool in God’s creation or whether the metaverse will move us past traditional notions of God. In this story, I introduce some of the characters who engage in and contribute to this argument. My story also animates some of the argumentative moves that these characters make.
