Proposed Inflammatory Effects of Ozone and I-Pinene Products on Human Lung Cells
Creators: name: Bray, Kirsten N.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2003

description: Ozone and aromatic compounds, like those in the volatile organic compounds (VOC), have a history of interacting with chemicals in the atmosphere. Many compounds such as terpenes are semi-volatile in nature and ozone itself is a highly reactive gas. Such combinations produce usually irritating, potentially carcinogenic by-products. Models of chemical reactions hypothesized then proved production of aromatic aerosol products from natural and man-made sources. There has been speculation surrounding multigenerational organic products concentrating on secondary aerosols (SOA). Now, there is increasing evidence of ozone's genomic effects along with specific inflammatory responses from SOA. Alpha pinene, which is related terpenes such as limonene, has multiple degradation products. So, the potential for increasing production of hazardous particulate, pollutant matter rises. Ozone and alpha pinenes separately irritate lung tissue of animals and or humans. Until recent studies, the two have not been examined together. It is the intention of this thesis to examine the hypothetical results of inflammatory reactions human lung cells undergo after combining two documented pollutants—ozone and alpha pinenes.

description: The classification of local Artinian Gorenstein algebras is equivalent to the study of orbits of a certain non-reductive group action on a polynomial ring. We give an explicit formula for the orbits and their tangent spaces. We apply our technique to analyse when an algebra is isomorphic to its associated graded algebra. We classify algebras with Hilbert function (1, 3, 3, 3, 1), obtaining finitely many isomorphism types, and those with Hilbert function (1, 2, 2, 2, 1, 1, 1). We consider fields of arbitrary, large enough, characteristic.

description: The differential cross section for gravitational photon-photon scattering calculated in Perturbative Quantum Gravity is shown to depend on the degree of polarization entanglement of the two photons. The interaction between photons in the symmetric Bell state is stronger than between not entangled photons. In contrast, the interaction between photons in the anti-symmetric Bell state is weaker than between not entangled photons. The results are interpreted in terms of quantum interference, and it is shown how they fit into the idea of distance-dependent forces.

Susceptibility to Lead Toxicity
Creators: name: Mehta, Neha J.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1999

description: Lead is a bluish-gray metal found in the earth's crust and does not occur naturally in humans. The metal is dense, malleable, resistant to corrosion, and has a low melting point. The most common forms of lead occur as lead oxides, lead salts, and organic salts. Due to its use in industrial activities, lead has been distributed widely, and is ubiquitous in the environment today. Humans have lead in their bodies as a result of exposure to the man made sources. Lead bioaccumulates and persists in living organisms. It has no known physiological function and has been identified as a toxin in humans. The toxic effects of lead in the human body are known to cause developmental, neurological, reproductive, and cellular damage (Yule, 1992). Lead is classified as a priority pollutant on the Superfund hazardous waste sites (Federal Register 1998). Increased health concerns regarding lead exposure have significantly decreased the use of lead in gasoline, paints, ceramic products, caulking, and pipe solder (Hunter 1977). Despite substantial reductions of lead exposures over the past 25 years, lead poisoning continues to be a serious health risk, especially for children. Chronic exposures to low levels of lead are an environmental reality in the United States today (NIEHS/USEPA 1999). Investigating factors that confer individual susceptibility to lead toxicity is imperative to setting environmental and occupational standards that are protective of public health. Lead abatement programs have been studied for their effectiveness in reducing blood lead levels. Several studies have found that improper lead abatement practices can actually increase lead levels in children. Results indicate that any type of abatement method—soil, dust, paint, and educational intervention—must be thorough and continual in order to be beneficial. Abated areas often become recontaminated or actually expose people to higher levels of lead than pre-abatement conditions. Favorable results are most often seen when a combination of proper abatement techniques are utilized (ISSI, 1999). Measuring the amount of lead in the blood is considered to be the most useful screening and diagnostic test for lead exposure. This measurement, referred to as the blood lead level, reflects lead's dynamic equilibrium between absorption, excretion, and deposition in soft- and hard-tissue compartments. Blood lead levels often underrepresent the total body burden, but they are still a widely accepted measurement of exposure to lead. This is due to the fact that blood lead levels respond relatively rapidly to changes in lead intake and, within a limited range, have a linear relationship to intake levels (ATSDR 1992).

description: Single-crystal diamond cavity optomechanical devices are a promising example of a hybrid quantum system: by coupling mechanical resonances to both light and electron spins, they can enable new ways for photons to control solid state qubits. However, realizing cavity optomechanical devices from high quality diamond chips has been an outstanding challenge. Here we demonstrate single-crystal diamond cavity optomechanical devices that can enable photon-phonon-spin coupling. Cavity optomechanical coupling to $2\,\text{GHz}$ frequency ($f_\text{m}$) mechanical resonances is observed. In room temperature ambient conditions, these resonances have a record combination of low dissipation (mechanical quality factor, $Q_\text{m} > 9000$) and high frequency, with $Q_\text{m}\cdot f_\text{m} \sim 1.9\times10^{13}$ sufficient for room temperature single phonon coherence. The system exhibits high optical quality factor ($Q_\text{o} > 10^4$) resonances at infrared and visible wavelengths, is nearly sideband resolved, and exhibits optomechanical cooperativity $C\sim 3$. The devices' potential for optomechanical control of diamond electron spins is demonstrated through radiation pressure excitation of mechanical self-oscillations whose 31 pm amplitude is predicted to provide 0.6 MHz coupling rates to diamond nitrogen vacancy center ground state transitions (6 Hz / phonon), and $\sim10^5$ stronger coupling rates to excited state transitions.

description: The UNC passive aerosol sampler measures mass concentrations and size distributions of indoor, outdoor, and occupational particulate matter. This study assessed the precision of passive sampler measurements using data from duplicate pairs of samplers that were deployed in a large field study. Particle count and size data were used to calculate PM[25] and PM[10] concentrations. To determine precision, the concentrations measured by duplicate samplers were compared to one another. Results showed that this sampler provides mass concentrations of PM[25] and PM[10] in the field with relative standard deviations that approach about 15%, with greater precision associated with higher concentrations. Variability between measurements was associated with counting statistics and with differences in the open area of the passive sampler mesh screen.

Application of a Lung Deposition Model to Fiber Data from Three North Carolina Asbestos Textile Plants

Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2008

description: We applied a lung deposition model to fiber data to produce nasopharyngeal, tracheobronchial, and pulmonary dose estimates received by workers in three asbestos Textile plants. A published fiber deposition model was chosen and the TPSPLINE SAS procedure was used to fit nonparametric regression models to estimate regional lung deposition fractions based on fiber aerodynamic diameter and length. These models were then applied to size-specific fiber data by transmission electron microscopy (TEM) to estimate size-specific fiber deposition by lung region. These size-specific deposition fractions were used in conjunction with the TEM-size data to estimate adjustments to phase contrast microscopy (PCM) fiber concentrations to express equivalent regional lung doses. The resulting deposition factors were compared across plants and departments. The Marshville plant had the highest deposition factor averages for all lung regions while the Davidson plant had the lowest averages for all lung regions. The range of these factors was 1.44-3.40 fibers deposited per unit PCM for nasopharyngeal deposition, 0.45-1.30 fibers deposited per unit PCM for tracheobronchial deposition, and 2.89-11.13 fibers deposited per unit PCM for pulmonary deposition. The plant and department-specific deposition factors, when multiplied by estimated daily average PCM concentrations and estimated inhaled air volumes, will result in lung region-specific fiber dose estimates. These resulting dose estimates will be used in a cohort mortality study.

description: We perform a systematic Bayesian analysis of rotation vs. dispersion support ($v_{\rm rot} / σ$) in $40$ dwarf galaxies throughout the Local Volume (LV) over a stellar mass range $10^{3.5} M_{\rm \odot} < M_{\star} < 10^8 M_{\rm \odot}$. We find that the stars in $\sim 80\%$ of the LV dwarf galaxies studied -- both satellites and isolated systems -- are dispersion-supported. In particular, we show that $6/10$ *isolated* dwarfs in our sample have $v_{\rm rot} / σ< 1.0$. All have $v_{\rm rot} / σ\lesssim 2.0$. These results challenge the traditional view that the stars in gas-rich dwarf irregulars (dIrrs) are distributed in cold, rotationally-supported stellar disks, while gas-poor dwarf spheroidals (dSphs) are kinematically distinct in having dispersion-supported stars. We see no clear trend between $v_{\rm rot} / σ$ and distance to the closest $\rm L_{\star}$ galaxy, nor between $v_{\rm rot} / σ$ and $M_{\star}$ within our mass range. We apply the same Bayesian analysis to four FIRE hydrodynamic zoom-in simulations of isolated dwarf galaxies ($10^9 M_{\odot} < M_{\rm vir} < 10^{10} M_{\rm \odot}$) and show that the simulated *isolated* dIrr galaxies have stellar ellipticities and stellar $v_{\rm rot} / σ$ ratios that are consistent with the observed population of dIrrs *and* dSphs without the need to subject these dwarfs to any external perturbations or tidal forces. We posit that most dwarf galaxies form as puffy, dispersion-dominated systems, rather than cold, angular momentum-supported disks. If this is the case, then transforming a dIrr into a dSph may require little more than removing its gas.

A Quicker, Cheaper Method to Quantify Total Carbonyls in Air and Biological Samples
Creators: name: Perlmutt, Lars D.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2009

description: Carbonyl compounds exist in air, water, food, biological fluids and tissues, as well as nonbiological materials. Many methods have been developed to detect carbonyl compounds in the air, including numerous derivatization reagents to make carbonyl compounds more stable, multiple extraction methods, as well as multiple detection methods. These methods can be costly and time consuming, and also make use of toxic solvents. We sought a quick and inexpensive method to detect and quantify total carbonyls in air samples, specifically diesel exhaust samples, as well as extra cellular media in biological samples. We derivatized standard carbonyl compounds with 2,4-dinitrophenyl hydrazine(DNPH); heptane was more efficient than pentane or hexane in extraction of the derivatives and leaves excess DNPH almost entirely in the aqueous phase. To test the usefulness of this technique carbonyls from diesel exhaust were collected on Sep-Pak DNPH-Silica cartridges, eluted, extracted with heptane, and analyzed by spectrophotometry and HPLC/UV/MS. Linear regression analysis indicated a strong correlation (0.9821) between the UV absorbance (365nm) of each sample and the total mass of carbonyl derivatives separated by HPLC and determined by MS. The usefulness of this technique was also tested on a biological sample. BEAS- 2B cells were exposed to differing concentrations of residual oil fly ash (ROFA). UV absorbance increased with increasing ROFA concentrations, suggesting that carbonyl groups (products of lipid peroxidation) increased with increasing concentrations of ROFA. These results indicate that a quick and inexpensive method to detect and quantify total carbonyls in air samples, specifically diesel exhaust samples, as well as extracellular media in biological samples, may be achieved through the extraction of carbonyl derivatives with heptane and subsequent detection by spectrophotometry. In the future, there is potential to use this method to detect carbonyls in food and water samples.

A Tight Binding Approach to Strain and Curvature in Monolayer Transition-Metal Dichalcogenides

description: We present a model of the electronic properties of monolayer transition-metal dichalcogenides based on a tight binding approach which includes the effects of strain and curvature of the crystal lattice. Mechanical deformations of the lattice offer a powerful route for tuning the electronic structure of the transition-metal dichalcogenides, as changes to bond lengths lead directly to corrections in the electronic Hamiltonian while curvature of the crystal lattice mixes the orbital structure of the electronic Bloch bands. We first present an effective low energy Hamiltonian describing the electronic properties near the K point in the Brillouin zone, then present the corrections to this Hamiltonian due to arbitrary mechanical deformations and curvature in a way which treats both effects on an equal footing. This analysis finds that local area variations of the lattice allow for tuning of the band gap and effective masses, while the application of uniaxial strain decreases the magnitude of the direct band gap at the K point. Additionally, strain induced bond length modifications create a fictitious gauge field with a coupling strength that is smaller than that seen in related materials like graphene. We also find that curvature of the lattice leads to the appearance of both an effective in-plane magnetic field which couples to spin degrees of freedom and a Rashba-like spin-orbit coupling due to broken mirror inversion symmetry.

Ultra-relativistic spinning particle and a rotating body in external fields

description: We use the vector model of spinning particle to analyze the influence of spin-field coupling on the particle's trajectory in ultra-relativistic regime. The Lagrangian with minimal spin-gravity interaction yields the equations equivalent to the Mathisson-Papapetrou-Tulczyjew-Dixon (MPTD) equations of a rotating body. We show that they have unsatisfactory behavior in the ultra-relativistic limit. In particular, three-dimensional acceleration of the particle increases with velocity and becomes infinite in the ultra-relativistic limit. The reason is that in the equation for trajectory emerges the term which can be thought as an effective metric generated by the minimal spin-gravity coupling. Therefore we examine the non-minimal interaction through the gravimagnetic moment $κ$, and show that the theory with $κ=1$ is free of the problems detected in MPTD-equations. Hence the non-minimally interacting theory seem more promising candidate for description of a relativistic rotating body in general relativity. The Lagrangian for the particle in an arbitrary electromagnetic field in Minkowski space leads to generalized Frenkel and Bargmann-Michel-Telegdi equations. The particle with magnetic moment in electromagnetic field and the particle with gravimagnetic moment in gravitational field have very similar structure of equations of motion. In particular, the spin-electromagnetic coupling also produces an effective metric for the particle with anomalous magnetic moment. If we use the usual special-relativity notions for time and distance, then the critical speed, which the particle cannot exceed during its evolution in electromagnetic field, is different from the speed of light. This can be corrected assuming that the three-dimensional geometry should be defined with respect to the effective metric.

Occupational Exposures (Metals, Solvents, and Pesticides) and Development of ANCA-Associated Small-Vessel Vasculitis (ANCA-SVV) with Glomerular Involvement: A Case-Control Study
Creators: name: Imler, Andrew J.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries

description: Workers are exposed to various environmental agents throughout their lifetimes. Several studies have identified associations between exposure to metals, solvents, and pesticides with chronic renal disease, but few studies have focused specifically on ANCA-glomerulonephritis (GN), a disease often associated with substantial morbidity and mortality. We investigated if associations exist between exposure to metals, solvents, or pesticides and ANCA-GN in a population-based (southeastern U.S.) case-control study. Occupational history and demographic data were collected from 131 cases and 109 controls using computerized telephone interviews. The data were analyzed using multivariate logistic regression while controlling for age, gender, state of residence, and silica exposure. No significant association was observed between exposure (ever versus never) to metals (OR=0.83, CI=0.38-1.81, p-value=0.64) or solvents (OR=1.09, CI=0.57-2.10, p-value=0.80) with ANCA-GNor between duration of exposure (years) and the disease. However, there was a trend observed for an association between a history of pesticide exposure (ever versus never) and ANCA-GN (OR=2.02, CI=0.96-4.24, p-value=0.06). Investigation on duration of pesticide exposure and the intensity of exposure for each of the three exposures described is warranted to gain further insight into their association with ANCA-GN.

Creators: name: Love, David C.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2004

description: Seventy-six million illnesses and 5,200 deaths are estimated to occur each year in the United States associated with foodborne transmission of microbial pathogens. Viral pathogens cause an estimated 7 out of 10 foodborne illnesses of known etiology. Improved methods to recover and detect viruses in foods may reduce morbidity and mortality associated with foodborne disease by identifying routes of viral transmission and by improving source tracking for foodborne outbreaks. Methods were developed and evaluated for recovery and detection of an enteric human virus. Hepatitis A virus (HAV), and an indicator virus, F+ RNA coliphage MS2(MS2), in foods commonly associated with viral foodborne outbreaks. In this study, HAV was inoculated into tomato sauce, strawberries, and oysters, then recovered by either an acid-adsorption-elution-concentration (AA/E) method or an alkaline-elution-concentration method. Viruses were detected and enumerated by cell infectivity or by molecular methods. For molecular detection and quantification, viral RNA was extracted and amplified by conventional, nested, or realtime RT-PCR. The results of this study indicate that the AA/E method, initially used to recover low levels of enteric viruses from shellfish, may also be applied for the recovery of viruses from other complex foods, such as produce and sauces. Additionally, produce and sauces contain fewer enzymatic inhibitors to molecular detection than oysters. Because of this, larger produce and sauce samples can be analyzed by molecular detection methods, leading to possibly lower virus detection levels and greater assay sensitivity in these foods.

description: Corda, Mosquera Cuesta and Lorduy Gomez have shown that spherically symmetric stationary states can be used as a model for galaxies in the framework of the linearized R^2 gravity. Those states could represent a partial solution to the Dark Matter Problem. Here we discuss an improvement of this work. In fact, as the star density is a functional of the invariants of the associated Vlasov equation, we show that any of these invariants is in its turn a functional of the local energy and the angular momentum. As a consequence, the star density depends only on these two integrals of the Vlasov system. This result is known as the "Jeans theorem". In addition, we find an analogous of the historical Tolman- Oppenheimer-Volkov equation for the system considered in this paper. For the sake of completeness, in the final Section of the paper we consider two additional models which argue that Dark Matter could not be an essential element.

description: We investigate the spectral statistics of the difference of two density matrices, each of which is independently obtained by partially tracing a random bipartite pure quantum state. We first show how a closed-form expression for the exact joint eigenvalue probability density function for arbitrary dimensions can be obtained from the joint probability density function of the diagonal elements of the difference matrix, which is straightforward to compute. Subsequently, we use standard results from free probability theory to derive a relatively simple analytic expression for the asymptotic eigenvalue density (AED) of the difference matrix ensemble, and using Carlson's theorem, we obtain an expression for its absolute moments. These results allow us to quantify the typical asymptotic distance between the two random mixed states using various distance measures; in particular, we obtain the almost sure asymptotic behavior of the operator norm distance and the trace distance.

description: We calculate a measure of superposition macroscopicity $\mathcal{M}$ for a superposition of screening current states in a superconducting flux qubit (SFQ), by relating $\mathcal{M}$ to the action of an instanton trajectory connecting the potential wells of the flux qubit. When a magnetized Bose-Einstein condensed (BEC) gas containing $N_{B}\sim \mathcal{O}(10^6)$ atoms is brought into a $\mathcal{O}(1)$ $μ\text{m}$ proximity of the flux qubit in an experimentally realistic geometry, we demonstrate the appearance of a two- to five-fold amplification of $\mathcal{M}$ over the bare value without the BEC, by calculating the instantion trajectory action from the microscopically derived effective flux Lagrangian of a hybrid quantum system composed of the flux qubit and a spin-$F$ atomic Bose gas. Exploiting the connection between $\mathcal M$ and the maximal metrological usefulness of a multimode superposition state, we show that amplification of $\mathcal{M}$ in the ground state of the hybrid system is equivalent to a decrease in the quantum Cramér-Rao bound for estimation of an externally applied flux. Our result therefore demonstrates the increased usefulness of the BEC--SFQ hybrid system as a sensor of ultraweak magnetic fields below the standard quantum limit.

Synthesis, Structural Characterization and Identification of Metabolites of Nitroarenes
Creators: name: Ramachandran, Priya
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1995

description: Nitroarenes are a class of fused ring aromatic hydrocarbons substituted with nitro groups. They are released into the environment by combustion processes. Nitropyrenes and nitrofluoranthenes are of particular importance because of the mutagenic and carcinogenic properties that they display. Efficient and convenient routes of preparation of the individual nitropyrenol, acetamidopyrenol, nitrofluoranthenol and acetamidofluoranthenol isomers in high purity and good yields are described here. The approach to synthesis was acetylation in the case of the pyrene metabolites and benzoylation in the case of the fluoranthene metabolites, followed by conversion to the corresponding ester and nitration. Purification was carried out before or after hydrolysis of the ester, based on the ease of separation of the esters compared to the phenols. The metabolites synthesized were then characterized by H^1-NMR and mass spectrometry.

Incorporating Astrophysical Systematics into a Generalized Likelihood for Cosmology with Type Ia Supernovae

description: Traditional cosmological inference using Type Ia supernovae (SNeIa) have used stretch- and color-corrected fits of SN Ia light curves and assumed a resulting fiducial mean and symmetric intrinsic dispersion for the resulting relative luminosity. As systematics become the main contributors to the error budget, it has become imperative to expand supernova cosmology analyses to include a more general likelihood to model systematics to remove biases with losses in precision. To illustrate an example likelihood analysis, we use a simple model of two populations with a relative luminosity shift, independent intrinsic dispersions, and linear redshift evolution of the relative fraction of each population. Treating observationally viable two-population mock data using a one-population model results in an inferred dark energy equation of state parameter $w$ that is biased by roughly 2 times its statistical error for a sample of N $ \gtrsim$ 2500 SNeIa. Modeling the two-population data with a two-population model removes this bias at a cost of an approximately $\sim20\%$ increase in the statistical constraint on $w$. These significant biases can be realized even if the support for two underlying SNeIa populations, in the form of model selection criteria, is inconclusive. With the current observationally-estimated difference in the two proposed populations, a sample of N $ \gtrsim$ 10,000 SNeIa is necessary to yield conclusive evidence of two populations.

description: There is concern that political deepfakes (AI-doctored videos of politicians speaking) may mislead voters; and there have been several studies evaluating the impact of deepfake exposure on belief in the content of the faked videos (e.g., Wittenberg et. al 2021; Vaccari & Chadwick 2020). The study in this pre-analysis plan assesses whether presenting real news articles about deepfakes makes people less likely to rely on video sources for truthful information. Much like warnings about textual fake news caused people to disbelieve real headlines (Clayton et al. 2019), we suspect news media information about deepfakes may make people less likely to rely on video footage when financially incentivized to gather factual information about politicians’ views. We also expect that the people who are least susceptible to misinformation (those who score high on Cognitive Reasoning Test (Pennycook & Rand 2019), measures of digital literacy (Guess et al. 2021), and political knowledge (Lupia 2016)) will not be less likely than other participants (i.e., those who score low on CRT, digital literacy and political knowledge metrics) to change their preferred sources of political information away from direct video as a result of a deepfake informational treatment. Instead, we predict these technically and politically savvy participants may become more skeptical of real video and commit more false positive errors than their less-informed counterparts.

WM and ADHD on image viewing

description: We report two experiments investigating the effect of working memory (WM) load on selective attention. Experiment 1 was a modified version of Lavie et al. (2004) and confirmed that increasing memory load disrupted performance in the classic flanker task. Experiment 2 used the same manipulation of WM load to probe attention during the viewing of complex scenes, while also investigating individual differences in ADHD traits. In the image viewing task, we measured the degree to which fixations targeted each of two crucial objects: (1) a social object (a person in the scene) and (2) a non-social object of higher or lower physical salience. We compared the extent to which increasing WM load would change the pattern of viewing of the physically salient and socially salient objects. If attending to the social item requires greater default voluntary top-down resources, then the viewing of social objects should show stronger modulation by WM load compared to viewing of physically salient objects. The results showed that the social object was fixated to a greater degree than the other object (regardless of physical saliency). Increased saliency drew fixations away from the background leading to slightly increased fixations on the non-social object, without changing fixations on the social object. Increased levels of ADHD-like traits were associated with fewer fixations on the social object, but only in the high salient, low load condition. Importantly, WM load did not affect number of fixations on the social object. Such findings suggest rather surprisingly that attending to a social area in complex stimuli is not dependent on the availability of voluntary top-down processes.
