Studies in Oxidative Chemistry: Oxidation of Benz[a]anthracene Using a Synthetic Porphyrin Catalyst to Model Cytochrome P-450
Creators: name: Brust, Kirstin
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1991

description: Oxidations of the PAH benz[a]alanthracene were carried out using m-chloroperoxybenzoic acid as monooxygen donor and the 2,6-chlorotetraphenyl-substituted iron porphyrin as catalyst. These reactions were performed in two different modes. The first used the oxoferryl porphyrin cation radical as direct oxidant, essentially allowing only one turnover of catalyst, whereas the second used the high-valent complex in a multi-turnover, catalytic mode. Phenoxathiin hexachloroantimonate was used as a model one-electron oxidant to compare its product profile to the other modes. Identical products (or substitution at the same carbon) in the other modes would provide support for a one-electron pathway. 18^0-labelled mCPBA was used in oxidations to provide direct evidence for involvement of the peroxyacid as the monooxygen donor, and 18^0 incorporation in the oxidized PAH was observed. Analysis of the product profiles in the three different oxidations supports one-electron oxidation as the major pathway operating. The products of the porphinatoiron-mediated oxidation are also postulated to depend on the relative amounts of substrate and available catalyst present during the oxidation.

description: A Partial Victory the decision in Debra H. v.\n Id.87 North Carolina's appellate court also applied the same basic features in Mason v. Dwinnell. Although it did not articulate a specific test, the court accorded a functional parent standing to seek custody, looking to (1) the couple's agreement to share in "all major decisions regarding their child"; (2) the functional parent's deliberate assumption of "emotional and financial care and support, guidance and decision-making" to the point of "equal participation"; and (3) the functional parent's "psychological parenting relationship" with the child.89 Thus while some states call mothers like Debra H. a de facto or psychological parent, some find that she stands in loco parentis or that exceptional circumstances warrant standing, and some prefer not to rely on strict terms or tests.

description: We provide a self-contained review of master equation approaches to modelling phonon effects in optically driven self-assembled quantum dots. Coupling of the (quasi) two-level excitonic system to phonons leads to dissipation and dephasing, the rates of which depend on the excitation conditions, intrinsic properties of the QD sample, and its temperature. We describe several techniques, which include weak-coupling master equations that are perturbative in the exciton-phonon coupling, as well as those based on the polaron transformation that can remain valid for strong phonon interactions. We additionally consider the role of phonons in altering the optical emission characteristics of quantum dot devices, outlining how we must modify standard quantum optics treatments to account for the presence of the solid-state environment.

Role of Mucus in the Pulmonary Toxicology of Inhaled Pollutants
Creators: name: Samet, James M.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1992

description: Lung mucus is a complex airway secretion whose primary function as part of the mucociliary clearance system is to serve as a renewable and transportable barrier against inhaled particulates and toxicants. The rheologic properties necessary for this function of mucus are imparted by glycoproteins, or mucins. Some respiratory disease states e.g., asthma, cystic fibrosis and bronchitis are characterized by quantitative and qualitative changes in mucus biosynthesis that contribute to pulmonary pathology. Similar alterations in various aspects of mucin biochemistry and biophysics, leading to altered mucus rheology and hypersecretion, result from inhalation of certain air pollutants such as SO2, O3, NO2 and cigarette smoke. The consequences of these pollutant-induced alterations in mucus biology are discussed in the context of pulmonary pathophysiology and toxicology.

title: Analysis of Environmental Influences for Simulation of Active Perception Sensors
Creators: name: Linnhoff, Clemens
Publisher: name: UNSPECIFIED
Year: 2023

description: Automated vehicles have an inherent safety risk for passengers and other traffic participant. Rigorous testing and safeguarding is needed for approving their operation on public roads. But testing in the real world is not only very time-consuming and expensive but also quite dangerous to participants and the engineers. Therefore more and more tests are relocated to the virtual world before they are performed on proving grounds and eventually in real traffic. In the real world, perception sensors of automated vehicles are subjected to a variety of adverse environmental conditions, such as fog, rain, snow, glaring sun light or road spray from other vehicles. As previous research already showed a severe impact on perception sensors, especially lidar, these influences need to be accurately represented in the virtual world and in models of the perception sensors. To systematically quantify the influence of the named conditions, they are first sorted into two main categories of object independent conditions, such as fog, rain, snow, and object dependent conditions, like wet pavement and road spray. For the first category, measurements in a stationary setup are recorded over a period of six months. Multiple lidar sensors with additional reference sensors for rain rate, temperature, sun brightness, visibility etc. deliver the data in this experiment. The measurements are sorted according to the weather condition and lidar values like the number of detections in the atmosphere are aggregated. This yields expectation values with respect to quantified environmental conditions. As a prominent example for object dependent conditions, road spray is examined in a second experimental setup. Measurements are taken with objects driving over artificially watered pavement on a proving ground. Water film and object velocities are systematically varied between experiment repetitions. The most prominent phenomenon in the recorded data is clustering of detections in the spray plume due to the turbulent nature of the spray. The clustering as well as detection probabilities within these clusters are used as expectation values for modeling. The gathered expectation values are then utilized to develop stochastic simulation models. The models are integrated into an lidar base model in a modular approach compliant to the Open Simulation Interface. The two main modeling approaches are adding false-positive atmospheric detections and attenuating or removing detections generated by the base model. Finally, the gained experiences from the measurements and model development are used to derive requirements for ground truth data quantifying the environmental conditions. The specified ground truth data serves as input to the simulation models.

description: The properties of Josephson tunneling between a single band s-wave superconductor and a two band $s_\pm$ superconductor are studied, in relation to recent experiments involving iron-based superconductors. We study a single junction and tune the order parameter (OP) phase difference across the junction. We find a variety of behaviors which are characterized by their energy-phase difference relation. The system is modeled on a lattice and treated in self-consistent mean field approximation. We also study a loop structure made with s-wave and $s_\pm$ parts with two junctions between the parts. The phase of the order parameter is then controlled by a magnetic flux threading the loop. Our analysis suggests four types of junction behaviors which are characterized by the dependence of the junction energy on the phase difference between the s-wave and the $s_\pm$ superconductors. The energy vs. phase difference curve has either one minimum at $Δϕ= 0,π$ or somewhere in between, or a double minimum structure. This leads to four different behaviors in a loop structure as a function of the flux threaded through the loop.

description: Daylighting is an urban drainage design concept that converts a stormwater culvert into an open channel to improve stormwater management, water quality and reduce peak runoff volumes. Daylighting streams on the UNC campus can also assist the University's goal of reducing nutrient runoff to Jordan Lake. This report analyzes the options for daylighting a 450-foot section of stormwater drainage pipe near the Forest Theatre on the University of North Carolina- Chapel Hill campus. The pipe discharges into Battle Branch Creek which empties into Bolin Creek eventually draining into Jordan Lake. This project analyzes alternative methods to transport the stormwater through the area, assesses the environmental and hydrologic benefits of these alternatives and determines the ecological benefits of a daylighted stream as compared to the current stormwater drainage culvert. An implementation plan was developed and total project costs were compared to the present value of future benefits.

description: We study the properties of excited states in one-dimensional many-body localized (MBL) systems using a matrix product state algorithm. First, the method is tested for a large disordered non-interacting system, where for comparison we compute a quasi-exact reference solution via a Monte Carlo sampling of the single-particle levels. Thereafter, we present extensive data obtained for large interacting systems of L~100 sites and large bond dimensions chi~1700, which allows us to quantitatively analyze the scaling behavior of the entanglement S in the system. The MBL phase is characterized by a logarithmic growth (L)~log(L) over a large scale separating the regimes where volume and area laws hold. We check the validity of the eigenstate thermalization hypothesis. Our results are consistent with the existence of a mobility edge.

description: A scenario of moduli stabilisation based on the interplay between closed and open string sectors is explored in a bottom-up approach. We study N=1 effective supergravities inspired by type IIB orientifold constructions that include background fluxes and non-perturbative effects. The former generate the standard flux superpotential for the axiodilaton and complex structure moduli. The latter can be induced by gaugino condensation in a non-Abelian sector of D7-branes and involve the overall Kaehler modulus of the compactification as well as matter fields. We analyse the dynamics of this coupled system and show that it is compatible with single-step moduli stabilisation in a metastable de Sitter vacuum. A novelty of the scenario is that the F-term potential suffices to generate a positive cosmological constant and to stabilise all moduli, except for a flat direction that can be either lifted by a mass term or eaten up by an anomalous U(1).

Evaluating Levels of Abstraction in Modeling: The Durham Mixed Integer Program
Creators: name: Tallmadge, Gregory John
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1997

description: The City of Durham's Water Resources Department operates a complicated water supply system consisting of multiple reservoirs, treatment plants, and pumping modes. The annual electrical operating cost for this system is approximately $600,000. Almost all of this cost is attributable to electric pumping. The Water Resources Department would like to minimize these costs, however, the complexity of the system and the electric tariff make it difficult to identify least-cost pumping patterns. The Durham Mixed Integer Program (MIP) was developed to provide the Water Resources Department with guidance in identifying these pumping patterns. A fundamental part of developing the MIP program was determining the appropriate levels of abstraction to use in representing the system elements. The principle of parsimony suggests that a simple model containing only the most essential elements of a system is preferable to a more complicated model which would include more detail, but fail to provide additional useful information. The key to applying this principle is determining which elements of the system are the most essential. The determination of these elements depends on the intended use of the model. This report describes the process whereby the appropriate levels of abstraction were determined for key elements of the Durham water supply system. These levels of abstraction were then evaluated to determine whether additional detail would improve the model's ability to identify least-cost operating strategies. The results of the analyses conducted indicated that the chosen levels of abstraction were, in general, sufficient for the intended use of the model. In addition, the analyses indicated the relative importance of finished water operations in determining total operating costs.

description: We present the Born-Markov approximated Redfield quantum master equation (RQME) description for an open system of non-interacting particles (bosons or fermions) on an arbitrary lattice of $N$ sites in any dimension and weakly connected to multiple reservoirs at different temperatures and chemical potentials. The RQME can be reduced to the Lindblad equation, of various forms, by making further approximations. By studying the $N=2$ case, we show that RQME gives results which agree with exact analytical results for steady state properties and with exact numerics for time-dependent properties, over a wide range of parameters. In comparison, the Lindblad equations have a limited domain of validity in non-equilibrium. We conclude that it is indeed justified to use microscopically derived full RQME to go beyond the limitations of Lindblad equations in out-of-equilibrium systems. We also derive closed form analytical results for out-of-equilibrium time dynamics of two-point correlation functions. These results explicitly show the approach to steady state and thermalization. These results are experimentally relevant for cold atoms, cavity QED and far-from-equilibrium quantum dot experiments.

Mass Transfer from Non-Aqueous Phase Liquids to the Aqueous Phase in Groundwater Systems
Creators: name: Poirier-McNeill, Michelle
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1989

description: As immiscible organic contaminants migrate through the subsurface environment, a significant portion of non-aqueous phase liquids (NAPL's) is trapped by capillary forces and remains in the subsurface as immobile blobs or ganglia. Residual saturations of NAPL on the order of 0 - 30 percent have been observed in saturated subsurface systems. The NAPL can partition into the aqueous phase and serve as a long-term source of groundwater contamination. NAPL-aqueous mass transfer rates impact the distribution and the rate of movement of the contaminant within the subsurface. The mass transfer coefficient is a function of many variables including aqueous phase velocity and NAPL-aqueous interfacial area. One-dimensional column experiments were performed in which the NAPL (toluene) is initially at residual saturation while the velocity of the aqueous-phase flow through the porous media (glass beads) is varied. Mass-transfer rates are quantified for the NAPL-aqueous phase system as a function of aqueous-phase velocity, porous media size, and percent NAPL saturation. Aqueous-phase velocities in the range of 0.1 to 35 m/d and NAPL saturations in the range of 2.5 to 21 percent are studied. The results of column experiments are shown in dimensionless form, and criteria are derived that show where the assumption of equilibrium between the NAPL and aqueous phase is appropriate. Initial solubility and mass transfer experiments were performed to determine the effect of humic acid and a cosolvent (ethanol) on NAPL-aqueous solubility and mass transfer characteristics. The results of this research indicate that the rate of NAPL-aqueous interphase mass transfer increases as a function of increasing aqueous phase velocity and percent NAPL saturation. The data indicates that NAPL-aqueous equilibrium is a valid assumption under the experimental conditions addressed in this study.

description: Depression negatively impacts the lives of many, and the rates are continuing to increase rapidly. However, the existing treatments and interventions for depression are often insufficient in fully alleviating symptoms and preventing relapse. Depression has been characterized by valenced patterns of high negative affectivity and low positive affectivity, yet the extent to which these relative patterns of affectivity change in response to intervention remains less clear. Identifying patterns of modifiable affective psychological mechanisms that contribute to reducing depression symptoms is critical to improve the effectiveness of wellbeing interventions for individuals with depressive disorders. In order to explore how affective patterns change in individuals with depression during a wellbeing intervention, the proposed study will evaluate affective patterns in college students (n = 93) with elevated depression symptoms who participated in a randomized controlled trial (RCT) of a mindfulness-based intervention (MBI) delivered via a mobile application (app), Headspace. MBIs are theorized to decrease negative emotions and enhance the capacity for the experience of positive emotions, which may be related to decreased depressive symptomatology. The affective patterns of interest in this exploratory study are changes in positive affect, negative affect, and emodiversity (i.e., the variety, or range, of emotions that humans experience). We will first identify which affective variables are most significantly related to change in depression symptoms, and then we will subsequently run analyzes to understand how these affective mechanisms function within the context of our RCT.

The Effects of Acute Isopropanol or Ethanol Exposure on the Hepatic Partitioning of Carbon Tetrachloride: An Additional Mechanism for Alcohol-Mediated Potentiation
Creators: name: Stanton, James K.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1998

description: Possible mechanisms underlying isopropanol and ethanol potentiation of carbon tetrachloride (CCI[4]) hepatotoxicity were investigated in male Fischer-344 rats (67-77 days old) In separate experiments, animals were dosed with isopropanol (0, 2.5, 5, 10 or 20 mmol/kg, p.o.) or ethanol (0, 5, 10, 20 or 40 mmol/kg, p.o.) in aqueous solutions. Eighteen hours later, animals were either terminated to determine the effects of alcohol alone or dosed with CCI[4] (0.0 or 0.5 mmol/kg in 10 percent Alkamuls solution, p.o.) Termination of alcohol plus CCI[4] animals occurred 24 hours post CCI[4]exposure. No increases in aspartate aminotransferase (AST), alanine aminotransferase (ALT), lactate dehydrogenase (LDH) and sorbitol dehydrogenase (SDH) activities were seen for either alcohol alone. Relative to CCI[4] alone, significant increases in AST, ALT, LDH and SDH were observed at all isopropanol dosages examined and only the two highest ethanol dosages. Isopropanol alone increased CYP2E1 activity beginning at 5 mmol/kg. The isopropanol dosage eliciting peakAST, ALT, LDH and SDH levels following isopropanol and CCI[4] exposure did not correspond with the dosage eliciting peak CYP2E1 induction. Two dosages of isopropanol resulted in similar CYP2E1 increases, but differed greatly in their potentiation of CCI[4] hepatotoxicity. Ethanol alone did not induce CYP2E1 activity. A dose-related increase in liver:blood CCI[4] partitioning was observed following exposure to isopropanol alone, but not to ethanol alone. Neither alcohol alone was observed to affect hepatic lipid concentrations. In conclusion, it appears that CYP2E1 induction is not the sole mechanism responsible for acute alcohol potentiation of CCI[4] hepatotoxicity. The data from this study suggest CYP2E1 induction and alteration of hepatic CCI[4] partitioning (but not alteration of hepatic lipid concentrations) as mechanisms of acute isopropanol potentiation of CCI[4] hepatotoxicity. In contrast, neither CYP2E1 induction nor alteration of hepatic CCI[4] partitioning appears to be involved in acute ethanol potentiation of CCI[4] hepatotoxicity, implying that an other, as yet unidentified, mechanism is involved.

description: The chromoelectric field generated by a static quark-antiquark pair, with its peculiar tube-like shape, can be nicely described, at zero temperature, within the dual superconductor scenario for the QCD confining vacuum. In this work we investigate, by lattice Monte Carlo simulations of the SU(3) pure gauge theory, the fate of chromoelectric flux tubes across the deconfinement transition. We find that, as the temperature is increased towards and above the deconfinement temperature $T_c$, the amplitude of the field inside the flux tube gets smaller, while the shape of the flux tube does not vary appreciably across deconfinement. This scenario with flux-tube "evaporation" above $T_c$ has no correspondence in ordinary (type-II) superconductivity, where instead the transition to the phase with normal conductivity is characterized by a divergent fattening of flux tubes as the transition temperature is approached from below. We present also some evidence about the existence of flux-tube structures in the magnetic sector of the theory in the deconfined phase.

In North Carolina, there are almost 3,000 public water supply systems and only 2% of these systems serve over 10,000 people. Most of the systems in the state (79%) serve fewer than 500 people. The North Carolina Department of Natural Resources has reported that quite a few systems in North Carolina are deficient in quantity, quality and/or operation and maintenance. The report examines regional water management in one county to assess the possibility of regionalization in North Carolina.

description: We study generalized electric/magnetic duality in Abelian gauge theory by combining techniques from locally covariant quantum field theory and Cheeger-Simons differential cohomology on the category of globally hyperbolic Lorentzian manifolds. Our approach generalizes previous treatments using the Hamiltonian formalism in a manifestly covariant way and without the assumption of compact Cauchy surfaces. We construct semi-classical configuration spaces and corresponding presymplectic Abelian groups of observables, which are quantized by the CCR-functor to the category of $C^*$-algebras. We demonstrate explicitly how duality is implemented as a natural isomorphism between quantum field theories. We apply this formalism to develop a fully covariant quantum theory of self-dual fields.

description: Safety behaviors are unnecessary actions taken to escape, prevent, or cope with a perceived threat (Telch & Lancaster, 2012). Safety behaviors have been studied in anxiety disorders but overlooked for those coping with traumatic events. This is surprising given that significant research has established that safety behaviors cause and maintain threat appraisals, and the major theories of PTSD (e.g., Ehlers et al., 2000; Foa et al., 1989; Rauch & Foa, 2006) implicate cognitive threat appraisals as an important causal maintaining factor in PTSD. Assessment tools for safety behaviors across a range of psychometric have been developed, but none of the existing posttraumatic safety behavior assessment tools are (1) concise and (2) applicable across trauma types. We developed the Posttraumatic Safety Behaviors Inventory (PSBI) to bridge this gap, and psychometrically evaluated the measure across two samples of trauma survivors recruited through Amazon Mechanical Turk.
An Evaluation of Biological Phosphorus Removal
Creators: name: Banks, Margaret K.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1985

description: Biological phosphorus removal (BPR) was examined to determine its feasibility as a phosphorous removal method for municipal wastewater. A literature search was conducted which reviewed previous research of the mechanism of phosphorus removal and the major biological phosphorus removal processes. A BPR experiment performed at the Mason Farm Wastewater Treatment Plant was reviewed and critiqued. The plant-scale experiment did not succeed because of 1) the presence of dissolved oxygen and nitrates in the anaerobic zone, 2) the low BOD concentration of the influent wastewater, and 3) the small portion of the return activated sludge which was treated anaerobically. A bench-scale BPR experiment was performed using the Mason Farm wastewater. The conclusions from the bench-scale experiment were that: 1) the release of phosphorus is an important step in the removal mechanism, 2) the phosphorus removing organisms may have a minimum requirement for organic carbon, and 3) a BOD concentration of greater than 200 mg/1 was needed for good phosphorus removal.
Coding in the Finite-Blocklength Regime: Bounds based on Laplace Integrals and their Asymptotic Approximations
Creators: name: Erseghe, Tomaso
Publisher: name: arXiv
Year: 2015
Subjects: subject: Information Theory (cs.IT)
subject: FOS: Computer and information sciences

description: In this paper we provide new compact integral expressions and associated simple asymptotic approximations for converse and achievability bounds in the finite blocklength regime. The chosen converse and random coding union bounds were taken from the recent work of Polyanskyi-Poor-Verdu, and are investigated under parallel AWGN channels, the AWGN channels, the BI-AWGN channel, and the BSC. The technique we use, which is a generalization of some recent results available from the literature, is to map the probabilities of interest into a Laplace integral, and then solve (or approximate) the integral by use of a steepest descent technique. The proposed results are particularly useful for short packet lengths, where the normal approximation may provide unreliable results.

Concentration and Molecular Detection of Norwalk Virus and other Viruses in Water
Creators: name: Simmons, Otto DeBruhl, III
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1995

description: Norwalk Virus (NV) and other human enteric viruses in fecally contaminated waters pose a human health risk that is inadequately characterized due to the limitations of current virus detection methods. Standard methods for virus concentration from water using electropositive adsorbent filters have not been tested for NV recovery because there is no convenient infectivity assay system and because the beef extract (BE/G) used to elute the adsorbed viruses inhibits virus detection by reverse transcriptase-polymerase chain reaction (RT-PCR) amplification. Hence, we tested five alternative eluents compatible with RT-PCR (the amino acids arginine, asparagine, glycine, lysine, orthreonine) for elution of NV as well as polio virus type 1 (PVl) and coliphage MS2 (MS2). All three viruses seeded in to dechlorinated tap water were adsorbed to Virosorb 1MDS filters and then eluted with either BE/G or an alternative eluent to achieve a 100-fold volume concentration. All three viruses were assayed by endpoint dilution RT-PCR and PVl and MS2 were assayed by infectivity using the plaque technique as well. With all of the amino acids except threonine, elution efficiency for all three viruses was comparable to or greater than that by BE/G. Virus recovery efficiencies were 50-75% over a pH range of 7.0-9.8. Viruses were concentrated an other 10-fold by polyethylene glycol precipitation, which was also compatible with molecular detection techniques and gave recovery efficiencies of 10-100%. These results indicate that modified filter adsorption-elution methods using amino acid eluents and subsequent secondary concentration by polyethylene glycol precipitation provide efficient concentration of NV and other viruses in water for subsequent assay by RT-PCR.
Impact of District-level Managerial Training of Kenya of Government Officials on the Scale-up of Community-Led Total Sanitation

description: Many organizations in the water, sanitation, and hygiene (WaSH) sector educate and train local stakeholders in order to increase the effectiveness and efficiency of their WaSH interventions. A key challenge has been measuring how well these training contribute to WaSH improvements and scale-up. I used a conceptual framework to evaluate a community-led total sanitation (CLTS) management training program in Kenya. Interviews guide were administered to 52 government officials in Kenya from June 2013 through July 2015. We evaluated trainings using three main themes: resource mobilization, partnership and supervision. The results showed that partnership skills were being applied by the trainees in their jobs. Trainees identified lack of quality supervision from the reflective training they were getting. Resource mobilization skill was not being used by most participants as there was a designated person within the ministry who was in-charge of this function. We suggest that our conceptual framework can support the design of future training programs and the evaluation of outcomes in the WaSH field.
