Optics Design And Fabrication For A Lung Interferometry-Radiography System, Rachael Lyn Blair

LSU Master's Theses

Purpose: High prevalence of lung diseases leads to many people worldwide needing spirometry and imaging testing. The typical imaging done uses chest radiography and/or low-dose CT. Lung tissue is difficult to visualize, making them substandard for monitoring lung disease progression. An improvement on these systems is x-ray interferometry which produces additional images that provide better visualization of changes in the lung tissue. The set-up of x-ray interferometry builds upon other imaging systems in that it includes diffraction gratings.

Materials: This thesis focused on implementing the fabrication processes to create diffraction gratings for a lung imager prototype that is currently under …

Teaching Stem For Social Justice: An Exploration And Analysis Of Teachers’ Pedagogical Content Knowledge, Zachary Minken

Graduate Theses & Dissertations

Research Problem

Reforms in Science, Technology, Engineering, and Mathematics education over the past several decades have resulted in a somewhat steady pressure to infuse personal, social, and cultural relevance into STEM education (DeBoer, 1991; Gallagher, 1971; Hekimoglu & Sloan, 2005; ITEEA, 1996, 2020; NCTM, 2000; NRC, 1989, 2009, 2010, 2012). This emphasis on relevance eventually resulted in a push for social justice in education as a means to both engage learners and to develop students’ moral and ethical reasoning abilities in hopes that this would lead to a more just world (Dos Santos, 2009; Zeidler, 2016). Amidst rising concerns for …

Selective And Brain-Penetrant Acss2 Inhibitors Target Breast Cancer Brain Metastatic Cells, Emily Esquea, Lorela Ciraku, Riley Young, Jessica Merzy, Alexandra Talarico, Nusaiba Ahmed, Mangalam Karuppiah, Anna Ramesh, Adam Chatoff, Claudia Crispim, Adel Rashad, Simon Cocklin, Nathaniel Snyder, Joris Beld, Nicole Simone, Mauricio Reginato, Alexej Dick

Kimmel Cancer Center Faculty Papers

Breast cancer brain metastasis (BCBM) typically results in an end-stage diagnosis and is hindered by a lack of brain-penetrant drugs. Tumors in the brain rely on the conversion of acetate to acetyl-CoA by the enzyme acetyl-CoA synthetase 2 (ACSS2), a key regulator of fatty acid synthesis and protein acetylation. Here, we used a computational pipeline to identify novel brain-penetrant ACSS2 inhibitors combining pharmacophore-based shape screen methodology with absorption, distribution, metabolism, and excretion (ADME) property predictions. We identified compounds AD-5584 and AD-8007 that were validated for specific binding affinity to ACSS2. Treatment of BCBM cells with AD-5584 and AD-8007 leads to …

Isaiah 53: Grammatical, Structural And Exegetical Observations, Felipe Braz Federson

Masters Theses

Isaiah 52:13-53:12 is a famous passage from the Tanakh that contains important grammatical constructions in Hebrew which, if translated incorrectly, can lead to erroneous exegetical and theological conclusions. Among these problems, the Servant’s relationship with the other characters in the passage is addressed. Through an analysis of the literary context and the structure of the text, not only are several exegetical possibilities substantiated, but two prototype translations are also provided, one based on the Leningrad Codex and another based on the Great Isaiah Scroll (1QIsa).

This dissertation explored the intersectionality between student voice and classroom management within middle school educational settings through the perspective of ten urban middle school teachers. Classroom management is defined as the array of techniques educators employ to foster an environment conducive to learning, often characterized by order, focus, and positivity. This encompasses the establishment of explicit expectations and procedures, adept handling of student behaviors, and the promotion of an ambiance that nurtures student engagement and scholastic achievement. The significance of adept classroom management is particularly pronounced in urban middle schools, where it is pivotal for engendering affirmative learning contexts. …

Investigating Small Drinking Water System Technical Capacity To Treat For Pfas, Chloe J. Yoder, Kaycie Lane

Department of Civil and Environmental Engineering: Faculty Publications

Per- and polyfluoroalkyl substances (PFAS) presents technical challenges in small systems where advanced drinking water treatment implementation is difficult. Publicly available data were used to examine technical treatment capacity for PFAS in the US, using Nebraska as a pilot. Of 1312 PWSs in Nebraska, 441 have technologies capable of removing PFAS from drinking water. Reverse osmosis was the most common treatment technology in Nebraska with 277 total systems using this technology with, 194 PWSs with RO serving populations of <= 100 people. Fifty-two PWSs had granular activated carbon, 47 had ion exchange and 62 had ultraviolet, with UV being primarily used for disinfection. We found PWSs had different technology deployment methods, several systems had “significant deficiencies” reported in management and operation evaluations, and age and previous water quality violations were not correlated to treatment evaluations. The developed methodology models utilizing publicly available data for contaminants across the US.

High-Dimensional Data Analysis Using Parameter Free Algorithm Data Point Positioning Analysis, S. M. F. D. Syed Mustapha

All Works

Clustering is an effective statistical data analysis technique; it has several applications, including data mining, pattern recognition, image analysis, bioinformatics, and machine learning. Clustering helps to partition data into groups of objects with distinct characteristics. Most of the methods for clustering use manually selected parameters to find the clusters from the dataset. Consequently, it can be very challenging and time-consuming to extract the optimal parameters for clustering a dataset. Moreover, some clustering methods are inadequate for locating clusters in high-dimensional data. To address these concerns systematically, this paper introduces a novel selection-free clustering technique named data point positioning analysis (DPPA). …

Antiseizure Properties Of Fenamate Nsaids Determined In Mature Human Stem-Cell Derived Neuroglial Circuits., Hamed Salmanzadeh, Robert F. Halliwell

School of Pharmacy Faculty Articles

Repeated and uncontrolled seizures in epilepsy result in brain cell loss and neural inflammation. Current anticonvulsants primarily target ion channels and receptors implicated in seizure activity. Identification of neurotherapeutics that can inhibit epileptiform activity and reduce inflammation in the brain may offer significant benefits in the long-term management of epilepsy. Fenamates are unique because they are both non-steroidal anti-inflammatory drugs (NSAIDs) and highly subunit selective modulators of GABA_A receptors. In the current study we have investigated the hypothesis that fenamates have antiseizure properties using mature human stem cell-derived neuro-glia cell cultures, maintained in long-term culture, and previously shown to …

Management Of Religion Teachers’ Socioemotional Competencies In Information And Communication Technologies Integration: A Phenomenographic Study, Mario Armando Cartagena Beteta, María Inmaculada Pedrera Rodríguez, Francisco Ignacio Revuelta Domínguez, Edith Soria Valencia

The Qualitative Report

This investigation forms part of a doctoral study that examines the relation between socioemotional competencies (SECs) and teachers’ beliefs on the integration of information and communication technologies (ICTs). It addresses religion teachers’ knowledge of SECs during the curricular integration of ICTs, specifically their internal aspects in their pedagogical practice using ICTs (second-order barriers). This study also discusses the characteristics of religion teachers, who have received less attention than teachers of science, language, or mathematics disciplines, partly because religion is not considered a priority area in educational policies. To this end, this study adopted a qualitative approach in the phenomenographic tradition …

The Effect Of Visual Sensory Interference During Multitask Obstacle Crossing In Younger And Older Adults, Hyeyoung Cho, Shirley Rietdyk

Faculty Publications

When older adults step over obstacles during multitasking, their performance is impaired; the impairment results from central and/or sensory interference. The purpose was to determine if sensory interference alters performance under low levels of cognitive, temporal, and gait demand, and if the change in performance is different for younger versus older adults. Participants included 17 younger adults (20.9±1.9 years) and 14 older adults (69.7±5.4 years). The concurrent task was a single, simple reaction time (RT) task: depress button in response to light cue. The gait task was stepping over an obstacle (8 m walkway) in three conditions: (1) no sensory …

Misstatements, Misperceptions, And Mistakes In Controlling For Covariates In Observational Research, Xiaoxin Yu, Roger S Zoh, David A Fluharty, Luis M Mestre, Danny Valdez, Carmen D Tekwe, Colby J Vorland, Yasaman Jamshidi-Naeini, Sy Han Chiou, Stella T Lartey, David B Allison

Children’s Nutrition Research Center Staff Publications

We discuss 12 misperceptions, misstatements, or mistakes concerning the use of covariates in observational or nonrandomized research. Additionally, we offer advice to help investigators, editors, reviewers, and readers make more informed decisions about conducting and interpreting research where the influence of covariates may be at issue. We primarily address misperceptions in the context of statistical management of the covariates through various forms of modeling, although we also emphasize design and model or variable selection. Other approaches to addressing the effects of covariates, including matching, have logical extensions from what we discuss here but are not dwelled upon heavily. The misperceptions, …

The Race For Increasing College Costs, Mark Jayson Farol

Undergraduate Economics Working Paper Series

As higher education continues to shift to be more progressive, providing access to more students of different backgrounds, it currently is facing an obstacle. The escalating cost of tuition is growing to be a significant concern for access to higher education. The government has prioritized increasing federal financial aid to improve accessibility. However, this intervention may paradoxically worsen the rise of the cost of college, as suggested by William Bennett's famous hypothesis. As the higher education landscape evolves, a nuanced examination of tuition rise drivers is essential. This study utilizes cross-sectional data from the National Center for Education Statistics to …
