From Flasks To Applications: Design And Optimization Of Giant Quantum Dots Using Traditional And Automated Synthetic Methods, Christina J. Hanson

Nanoscience and Microsystems ETDs

Semiconducting nanocrystals, also known as quantum dots (QDs), that emit light with near-unity quantum yield and are extremely photostable are attractive options as down-conversion and direct electricity-to-light materials for a variety of applications including solid-state lighting, display technologies, bio-imaging and optical tracking. Standard QDs with a core/thin shell structure display fluorescence intermittency (blinking) and photobleaching when exposed to prolonged room temperature excitation for single dot measurements, as well as significant reabsorption and energy transfer when densely packed into polymers or at high solution concentrations.

We have developed thick shell “giant” QDs (gQDs), ultra-stable photon sources both at the ensemble and …

Teachers’ Professional Identity Construction: A Narrative Inquiry Of Non-Native English Speaking Teachers In Saudi Arabia, Mustafa Abdo Hersi

Language, Literacy, and Sociocultural Studies ETDs

This qualitative study examineshow five in-service male non-native English speaking teachers (NNESTs) constructed and negotiated their professional identity as teachers to make meaning of their lived experiences in an EFL milieu, a Saudi Arabian university. The study also explores the challenges related to NNESTs’ teaching lives and how they negotiated them as they constructed their professional identities. I approached the studied phenomena by employing a narrative inquiry method. Data were collected through semi-structured interviews and an autobiography. The study draws on Clandinin and Connelly’s framework of three-dimensional space (temporality, sociality, and place), Bourdieu’s theory of forms of capital,and Gee’s …

Patient Specific Radiation Doses From Projection Radiography Images: Improving The Accuracy Of Low Dose Radiation Calculations, Daniel J. Sandoval

Nuclear Engineering ETDs

Due to an increase in regulatory scrutiny and medical facility accreditation requirements to monitor patient radiation dose from diagnostic imaging procedures, there is a growing necessity to determine and record accurate patient radiation dose from diagnostic medical imaging procedures. Current methods of patient dosimetry in diagnostic imaging are both extremely difficult and time consuming, require large computing resources (such as Monte Carlo computations), or lack accuracy due to using data based on homogeneous materials and “standard-man sized” anthropomorphic models.

This dissertation provides an algorithm that calculates a more accurate dose using patient-specific projection radiographic images. The algorithm includes measurements acquired …

An Exploration Of The Optical Detection Of Ionizing Radiation Utilizing Modern Optics Technology, Sean D. Fournier, Adam Hecht, Cassiano De Oliveira, Jeffrey B. Martin, Richard K. Harrison, Charles Potter

Nuclear Engineering ETDs

Modern ultraviolet (UV) cameras, when combined with UV-transmitting lenses/filter arrangements, can be used to detect radiation dose in air. Ionizing radiation excites nitrogen molecules in ambient air, the resulting decay includes weak emission of ultraviolet photons. Previous work has proven this phenomenon is detectable using highly-sensitive electronically cooled cameras traditionally used in astronomy for low-background imaging. While the ability to detect the presence of radiation (i.e. qualitative measurement) has been demonstrated at Sandia National Laboratories, there are several challenges in correlating images to known dose-fields (quantitative measurement). These challenges include: a low signal to background ratio, interferences due to electronic …

Moderate Prenatal Alcohol Exposure Impairs Performance In An Object-Place-Paired-Associate Task, Lilliana May Sanchez

Psychology ETDs

Memory impairments, including spatial and object processing, are often observed in individuals with Fetal Alcohol Spectrum Disorder. Much attention has been directed towards the hippocampus, which displays significant alterations after moderate prenatal alcohol exposure (PAE). In the present study, we tested a moderate PAE rat model in an object-place-paired-associate (OPPA) task, previously shown to require hippocampal processing. The OPPA task was composed of training rats to discriminate between an identical pair of objects presented in 180° opposite arms of a radial arm maze. Animals were given a total of 10 trials per day over 14 consecutive days of training and …

An Integrated Approach To Studying And Engineering Bacterial Type Ii Polyketide Core Structure Biosynthesis, Xuechen Zhu

Chemistry and Chemical Biology ETDs

Natural products including alkaloids, phenylpropanoids, polyketides, terpenoids and antibiotics provide abundant resources for drugs and drug leads. Type II polyketides (PK-IIs) are a large array of aromatic polyketides that have exhibited various bioactivities including anti-tumor, anti-cancer, anti-fungal and anti-bacteria. Based on the lengths of carbon chains and the cyclization patterns in their core structures, most bacterial PK-IIs have been classified into 6 typical classes: benzoisochromanequinone (BIQ), anthracycline (ANT), angucycline (ANG), tetracycline (TET), tetracenomycin (TCM) and pentangular (PEN). Bioengineering for diversification of PK-II core structures will generate libraries of bioactivities, which can serve the drug discovery in this family of compounds. …

An Update And Analysis Of The Corrales Bosque Preserve Vegetation Map, Brett Feldhahn

Water Resources Professional Project Reports

An updated vegetation map of the Corrales Bosque Preserve in Corrales, New Mexico was developed for this project using Hink and Ohmart community-structure survey protocol and vegetation classifications. The vegetation composition was analyzed and compared to the Middle Rio Grande Conservation Action Plan (MRG-CAP) rating criteria for dynamic mosaic vegetation, also known as the Dynamic Patch Mosaic (DPM). The DPM attribute indicates the mix of vegetation community types—the vegetation mosaic—that facilitates the best outcome for ecosystem resilience and biodiversity in the bosque. The updated vegetation community-structure types were used to classify each polygon into general vegetation types per the MRG-CAP, …

Alchemical Rulemaking And Ideological Framing: Lessons From The 40-Year Battle To Regulate Mercury Emissions From Electric Power Plants, Andrew Carter

Natural Resources Journal

Environmental mercury has long been linked to adverse health impacts on human populations. Globally ubiquitous at ambient levels in air and water, it can reach potentially unsafe levels in fish as it biologically magnifies and accumulates through aquatic and marine food webs. Vulnerable communities, including many communities of color, are particularly at risk from fish-borne mercury. Despite the fact that coal-fired electric generating units have been recognized as major sources of environmental mercury since the 1970s, and that the Environmental Protection Agency discussed possible future regulations of mercury emissions from such plants in 1975, it was not until 2014 that …

Investigation Of Anion And Cation Exchange Membranes For Enhancing Desalination And Power Generation In A Microbial Desalination Cell, Francisco Lopez Moruno

Civil Engineering ETDs

Microbial desalination cell (MDC) is a bioelectrochemical system capable of oxidizing organics, generating electricity and reducing the salinity content into the desalination chamber. In the first part of this study, quaternary ammonium poly(2,6-dimethyl 1,4-phenylene oxide) (QAPPO) anion exchange membranes (AEMs) with topographically patterned surfaces were assessed in a microbial desalination cell (MDC) system. The MDC results with these QAPPO AEMs were benchmarked against a commercially available AEM. The MDC with the non-patterned QAPPO AEM (Q1) displayed the best desalination rate (a reduction of salinity by 53±3 %) and power generation (189±5 mW m^-2) when compared against the commercially …

Brief For Professors, Lamar, Archer & Cofrin, Llp V. R. Scott Appling As Amicus Curiae, Laura Spitz

Faculty Scholarship

This brief is concerned with the Petitioner’s misinterpretation of §523(a)(2) of the United States Bankruptcy Code, 11 U.S.C. §101, et seq., which wrongly maintains that a false oral statement describing a single asset gives rise to a non-dischargeable debt. This brief shows Congress understood that §523(a)(2) simply re-enacted statutory language already having a completely settled understanding that a statement about a single asset was a “statement respecting financial condition” which must be in writing in order to give rise to a nondischargeable debt. This brief also submits that even if, arguendo, Petitioner were correct that a statement respecting financial condition …

Global Seawater Redox Trends During The Late Devonian Mass Extinction Detected Using U Isotopes Of Marine Carbonates, David Allen White

Earth and Planetary Sciences ETDs

The Late Devonian extinction ranks as one of the ‘big five’ Phanerozoic extinctions affecting up to 80% of marine species and occurred during five distinct pulses spanning /or widespread marine anoxia. We test the marine anoxia hypothesis by analyzing uranium isotopes (δ²³⁸U) across a ~7 My interval of well-dated Upper Devonian marine carbonates from the Devil’s Gate Limestone in Nevada, USA.

The measured δ²³⁸U curve shows no co-variation with local anoxic facies, water-depth dependent facies changes, redox-sensitive metals, TOC, or diagnostic elemental ratios indicating the δ²³⁸U curve was not controlled by local depositional or …

Systematic Size Control In The Synthesis Of Zero-Valent Iron Nanoparticles, Grant C. Bleier

Chemistry and Chemical Biology ETDs

A novel synthetic method for the production of highly magnetic, low size-dispersity nanoparticles through reversible magnetic agglomeration is introduced and studied in detail. Initially, a weakly coordinating surfactant (3-octadecyl-2,4-pentanedione) is employed to produce a wide range of nanoparticle sizes ranging from 8 to 20 nm in diameter. The kinetics faced in these reactions by cheap and widely available iron complex precursors can be avoided in this method with the introduction of thermodynamic control, which occurs in the form of a magnetic precipitation event that essentially halts nanoparticle growth. Utilizing this synthetic method, the length of the alkyl chain on the …

V-Atpase Roles In Prostate Cancer, Yamhilette Licon Munoz

Biomedical Sciences ETDs

Vacuolar ATPase (V-ATPase) is responsible for maintaining the acidic pH of the endomembrane system in eukaryotic cells. V-ATPase active transport of protons generates the differential luminal pH in lysosomes, endosomes, and the Golgi. In addition to intracellular V-ATPase, cancer cells have V-ATPase at the plasma membrane. Plasmalemmal V-ATPase acidifies the extracellular milieu and enhances cell motility and invasion, evidence that V-ATPase contributes to tumorigenic phenotypes. We studied V-ATPase cellular functions in prostate cancer (PCa), the most commonly diagnosed cancer for men in the United States. V-ATPase inhibitors decreased invasion and migration of PCa cells. In aggressive PCa cell lines, C4-2B …

Mathematical Modeling Of Nanoparticle Biodistribution, Prashant Dogra

Biomedical Sciences ETDs

The prospects of nanoparticle-based drug delivery and imaging have been hindered by insufficient understanding of the effects of nanoparticle physicochemical properties on their in vivo disposition. Here, we present an integrative mathematical modeling and in vivo imaging approach to quantify the relationship between nanoparticle physicochemical properties, namely, size, surface charge, and surface chemistry, on their in vivo disposition kinetics in healthy rats. We developed simple master equations in closed-form to accurately represent the time-dependent concentration of nanoparticles in different regions of the body and obtain functional relationships for predictive purpose to support rational design of nanomedicine. We further used …
