Phytoplankton Dynamics of Two North Carolina Coastal Plain Swamps: Species Composition, Seasonal Periodicity and Impact of Wastewater Discharge

description: INTRODUCTION: Wetland Values: Wetlands are valuable ecosystems which serve to interface land and water systems. Saturation of the soil and type of vegetation are major criteria which define wetlands (Cowardin, et al. 1979). These ecosystems support diverse plant and animal communities and the magnitude of primary productivity in wetlands is of global importance. In addition, wetlands provide sanctuary to many threatened and endangered species of plants and animals. Wetland ecosystems also have many valuable hydrologic functions. In palustrine forested wetlands, commonly called swamps, the inundation of the soil varies with the season and the amount of precipitation and runoff. One of the predominant values of wetlands is their capacity to serve as sites of water retention and flood control. They are also traps for suspended sediments and nutrients, thus improving the water quality downstream (Carter, et al.,1979). Because of their potential to improve water quality, wetlands have also been used as tertiary treatment for municipal wastewater discharge (Brinson and Westall, 1983; Richardson and Nichols, 1986), However, such uses are inappropriate if using the wetland as a site for sewage treatment will alter the valuable ecologic and hydrologic functions of the wetland.

description: The case studies in this document highlight five tips that may be beneficial to other countries or situations: 1. Focus on just a very few achievable indicators, foregrounding foundational learning, for a country emphasising learning. 2. Use data to drive both initial “wake-up” and stock taking but also to support teaching as the process goes along. 3. Emphasis on the teaching by the teachers who are already in place. 4. Provide strong motivation through support that works. 5. Use tight management so there is some degree of centralism and prescriptiveness as to pedagogy and other inputs, but after having iterated and adapted to context.

Phase space analysis of bulk viscous matter dominated universe

description: We consider a Friedmann model of the universe with bulk viscous matter and radiation as the cosmic components. We study the asymptotic properties in the equivalent phase space by considering the three cases for the bulk viscous coefficient as (i) $ζ= ζ_{0}$, a constant (ii) $ζ= ζ_{0} + ζ_{1}\frac{\dot{a}}{a}$, depending on velocity of the expansion of the universe and (iii) $ζ= ζ_{0} + ζ_{1}\frac{\dot{a}}{a} + ζ_{2}\frac{\ddot{a}}{\dot{a}}$, depending both on velocity and acceleration of the expansion of the universe. It is found that all the three cases predicts the late acceleration of the universe. However, a conventional realistic behaviour of the universe, i.e., a universe having an initial radiation dominated phase and then followed by decelerated matter dominated phase and then finally evolving to accelerated epoch, is shown only when $ζ= ζ_{0}$, a constant. For the other two cases, it does not show either a prior conventional radiation dominated phase or a matter dominated phase of the universe.

Effect of Operating Conditions On Pressure Drop in A Pulse-Jet Cleaned Fabric Filter

Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1986

description: A predictive model for pressure drop in a pulse-jet cleaned fabric filter and the effect of on-line vs. off-line pulse-jet cleaning on pressure drop were examined. Data were collected in experimentswith untreated polyester fabric and PTFE-laminated fabric. Twenty-four experimental conditions were studied in which each fabric repeatedly filtered limestone dust or flyash for 30, 120, or 480 s and was then cleaned either on-line or off-line. Each condition was replicated, resulting in a total of 48 experiments. Dust inlet concentration and superficial filtration velocity were maintained at 1.69 g m[-3] and 0.075 m s[-1] respectively. Based on conditions studied: 1) dust removal results from a complex interaction of the pulse pressure, pressure drop prior to pulsing, and dust areal density, w; 2) dust removal efficiency of a cleaning pulse, ε, increases as w increases, 3) the rate of increase in ε with w diminishes as w becomes larger; 4) the predictive model examined should be applied only if the dust areal density added during one filtration cycle, W[o], remains unchanged or if the rate of change in ε is small; 5) under some conditions off-line cleaning does not reduce pressure drop below that achieved by on-line cleaning; and 6) pressure drop depends primarily on fabric type and w[o].

description: Motivated by recent progress in electron quantum optics, we revisit the question of single-electron entanglement, specifically whether the state of a single electron in a superposition of two separate spatial modes should be considered entangled. We first discuss a gedanken experiment with single-electron sources and detectors, and demonstrate deterministic (i. e. without post-selection) Bell inequality violation. This implies that the single-electron state is indeed entangled and, furthermore, nonlocal. We then present an experimental scheme where single-electron entanglement can be observed via measurements of the average currents and zero-frequency current cross-correlators in an electronic Hanbury Brown-Twiss interferometer driven by Lorentzian voltage pulses. We show that single-electron entanglement is detectable under realistic operating conditions. Our work settles the question of single-electron entanglement and opens promising perspectives for future experiments.

A Cancer Risk Assessment of Low Level Vinyl Acetate Exposure Utilizing a Physiologically Based Pharmcokinetic Model
Creators: name: Baron, Karin Frances
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2001

description: Vinyl acetate (VA) is widely used in the chemical industry for the manufacturing of polyvinyl acetate emulsions, copolymers with ethylene for adhesives, and paper coatings. The International Agency for Research on Cancer (IARC) has classified vinyl acetate as a possible human carcinogen (IARC, 1995). There is sufficient evidence in the literature to indicate the carcinogenic potential to rats exposed by inhalation to vinyl acetate. There is limited epidemiological data to support a possible excess risk for cancer of the respiratory system with long-term exposure to industrial workers. In order to estimate more closely the risk at current occupational levels, a physiologically based pharmacokinetic (PBPK) model was constructed to predict human target tissue concentrations at plausible industrial exposures. These concentrations were then characterized and compared to tissue levels corresponding to doses known to be tumourigenic in animals to arrive at an estimation of human cancer risk. The model demonstrated that daily low level exposures to vinyl acetate pose a minimal threat of cancer risk to workers.

Interstrain Variability in Genotoxicity of 1,3 Butadiene May be a Result of Epigenetic and DNA Repair Mechanisms
Creators: name: O'Brien, Bridget
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2012

description: 1,3-Butadiene (BD) is a ubiquitous environmental pollutant and a widely used industrial chemical. It is known to be carcinogenic to humans via its genotoxic metabolites. Using inbred strains of mice known to have BD induced epigenetic alterations, we examined interstrain and gender differences in genotoxicity and epigenotoxicity. Males and females of each strain were inhalationally exposed to 0, 13, or 425 ppm BD for 6 hr/day, 5 days/week, for 2 weeks. DNA adducts, histone modifications, and expression of DNA repair and DNA and histone methylation genes were assessed. CAST/EiJ mice had lower levels of N-7-guanine adducts than other strains. Strain and gender differences were present in histone modifications associated with chromatin condensation and DNA damage recognition and repair. Gene expression of DNA repair enzymes suggests that ability to repair DNA damage is also important, providing additional information on interstrain and gender differences in the mode of toxicity of BD.

description: The bulk of the new empirical work on estimating the impact on learning of various education projects/ programmes/policies, while based on sound principles of estimating causal impacts, is far too inadequately theorised and specified to be of much immediate and direct use in formulating effective action to accelerate learning. Therefore, just “more of the same” empirical research is unlikely to be of much help or to add up to a coherent action or research agenda as it faces massive challenges of external and construct validity. The RISE research agenda is moving forward by: embedding research into a prior diagnostic of the overall system which allows a more precise characterisation of what “context” might mean; evaluating on-going attempts at education reform at scale (rather than isolated field experiments); specificity about the details of programme/project/policy design; and acknowledgment that policy relevant learning is itself part of the system, not a one-off exercise.

Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2005

description: Watershed modeling has emerged as an increasingly useful tool in relating water quality to specific sources of contaminants in the watershed and the mechanisms that control the dynamics of these contaminants. The United States Geological Survey's (USGS's) implementation of the spatially referenced regression SPARROW nutrient model explains much of the variation in nutrient concentrations in large, multi-state hydrologic units, but not without a considerable effort in database creation to support the model. This report explains the nature of these problems according to the tenets of the emergingfield of Geoinformatics, including proper metadata construction, database design, benchmarks, collaboration, standards and best practices. A procedure is documented for merging and correcting errors in water-related data in the translation between two federal agencies'databases.

description: An $F$-manifold is complex manifold with a multiplication on the holomorphic tangent bundle with a certain integrability condition. Important examples are Frobenius manifolds and especially base spaces of universal unfoldings of isolated hypersurface singularities. This paper reviews the construction of hermitian metrics on $F$-manifolds from $tt^*$ geometry. It clarifies the logic between several notions. It also introduces a new {\it canonical} hermitian metric. Near irreducible points it makes the manifold almost hyperbolic. This holds for the singularity case and will hopefully lead to applications there.

Assessment of predicted ozone formation in the United Arab Emirates
Creators: name: Xu, Yadong
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2011

description: We used the Community Multiscale Air Quality (CMAQ) model simulation to study ozone formation in the United Arab Emirates Model performance evaluation results indicate severe over-prediction of O3 and under-prediction of NO2 especially in the Abu Dhabi urban region with a normalized mean bias (NMB)for O3 at 179% and NO2 at -64% at urban monitoring site KHAF. We used the process analysis tools together with a post processor tool pyPA to investigate the possible factors causing the poor performance and assess potential major contributors to high ozone episodes in the model. The results indicate that the local photochemical production and advection processes were the main contributors to surface ozone in the UAE. We conducted two sensitivity runs in which NOx emissions are increased to understand model responses to different emission scenarios. Compared with the original model simulation, increasing the anthropogenic NOx emission rates by a factor of 6 in the Abu Dhabi urban region (the sensitivity run s2) caused significant predicted O3 decrease by up to 80ppb. The system switched from NOx-limited condition in the original model run to NOx-inhibited condition in the sensitivity run s2.

description: Spectral functions of the pseudoscalar $D$ meson in the nuclear medium are analyzed using QCD sum rules and the maximum entropy method. This approach enables us to extract the spectral functions without any phenomenological assumption, and thus to visualize in-medium modification of the spectral functions directly. It is found that the reduction of the chiral condensates of dimension 3 and 5 causes the masses of both $D^+$ and $D^-$ mesons to grow gradually at finite density. Additionally, we construct charge-conjugate-projected sum rules and find a $D^+$-$D^-$ mass splitting of about -15 MeV at nuclear saturation density.

Penalized complexity priors for degrees of freedom in Bayesian P-splines

Year: 2015

description: Bayesian P-splines assume an intrinsic Gaussian Markov random field prior on the spline coefficients, conditional on a precision hyper-parameter $τ$. Prior elicitation of $τ$ is difficult. To overcome this issue we aim to building priors on an interpretable property of the model, indicating the complexity of the smooth function to be estimated. Following this idea, we propose Penalized Complexity (PC) priors for the number of effective degrees of freedom. We present the general ideas behind the construction of these new PC priors, describe their properties and show how to implement them in P-splines for Gaussian data.

description: Quantum antiferromagnets have proven to be some of the cleanest realizations available for theoretical, numerical, and experimental studies of quantum fluctuation effects. At finite temperatures, however, the additional effects of thermal fluctuations in the restricted phase space of a low-dimensional system have received much less attention, particularly the situation in frustrated quantum magnets, where the excitations may be complex collective (bound or even fractionalized) modes. We investigate this problem by studying the thermodynamic properties of the frustrated two-leg S=1/2 spin ladder, with particular emphasis on the fully frustrated case. We present numerical results for the magnetic specific heat and susceptibility, obtained from exact diagonalization and quantum Monte Carlo studies, which we show can be rendered free of the sign problem even in a strongly frustrated system and which allow us to reach unprecedented sizes of L=200 ladder rungs. We find that frustration effects cause an unconventional evolution of the thermodynamic response across the full parameter regime of the model. However, close to the first-order transition they cause a highly anomalous reduction in temperature scales with no concomitant changes in the gap; the specific heat shows a very narrow peak at very low energies and the susceptibility rises abruptly at extremely low temperatures. Unusually, the two quantities have different gaps over an extended region of the parameter space. We demonstrate that these results reflect the presence of large numbers of multi-particle bound-state excitations, whose energies fall below the one-triplon gap in the transition region.

Detection of Norwalk Virus, Hepatitis A Virus, and Enterovirus in Wastewater by RT-PCR and Oligoprobe Hybridization
Creators: name: Tai, Ling
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1994

description: Acute gastroenteritis due to Norwalk Virus (NV) and infectious hepatitis due to Hepatitis A Virus (HAV) are important waterborne enteric diseases associated with sewage contamination. The levels of NV and HAV in water and wastewater are not clearly known due to the difficulties in cultivating these viruses and the insensitivity of conventional immunoassay and nucleic acid hybridization methods. The main goal of this work was to develop rapid and sensitive methods to detect NV, HAV, and entero viruses (EV) in sewage samples by RT-PCR-Oligoprobe (OP) hybridization. Three test viruses (NV, HAV, and poliovirus type 1(EV)) seeded into wastewater samples were recovered by polyethylene glycol (PEG)precipitation, organic solvent extraction (fluorocarbon or chloroform), and centrifugal ultrafiltration. When these methods were used to purify and concentrate intact viruses from 0.25 L volumes of raw sewage to <1.0 ml, virus recoveries averaged 23% for EV and 10% for HAV by infectivity assay and viruses were detected by direct RT-PCR and OP. Norwalk viruses were detectable by RT-PCR-OP in 0.25 L samples seeded with about 4 log[10] virions(lO[4]PCR unit). 80 PFU of poliovirus and 1,600 PFUof HAV in 250-ml raw sewage are detectable in the processed wastewater. The virus cconcentration and purification processes and RT-PCR-OP allowed detection of enteroviruses in unseeded raw sewage. The methods developed in this study are sensitive, simple and economical for detection of enteric viruses in wastewater samples.

description: We study the effect of varying the mass and volume fraction of a suspension of rigid spheres dispersed in a turbulent channel flow. We performed several Direct Numerical Simulations using an Immersed Boundary Method for finite-size particles changing the solid to fluid density ratio, the mass fraction and the volume fraction. We find that varying the density ratio between 1 and 10 at constant volume fraction does not alter the flow statistics as much as when varying the volume fraction at constant and at constant mass fraction. Interestingly, the increase in overall drag found when varying the volume fraction is considerably higher than that obtained for increasing density ratios at same volume fraction. The main effect at density ratios of the order of 10 is a strong shear-induced migration towards the centerline of the channel. When the density ratio is further increased up to 1000 the particle dynamics decouple from that of the fluid. The solid phase behaves as a dense gas and the fluid and solid phase statistics drastically change. In this regime, the collision rate is high and dominated by the normal relative velocity among particles.

description: Health disparities for breast cancer in African American women have been well documented; although they have a lower incidence compared to Non-Hispanic Whites, they experience a higher mortality and additionally, young African American women (less than 50 years old) experience higher prevalence of a more aggressive subtype called basal-like breast cancer. These disparities are tied to socio-economic, envirornmental and cultural factors. The most effective mechanisms of breast cancer education for this group of women involve culturally-sensitive, direct information provided through a variety of trusted sources, including media, lay community members and health professionals. Although studies have identified specific barriers that impede the relationship and communication between African American women and their health providers, few have examined how health professionals communicate breast cancer risk information to low income and/or African American women. For this reason, the UNC Breast Cancer and the Environment Research Program (UNC BCERP) explored health professionals' communication of breast cancer information with patients, with an emphasis on young African American women. Individual interviews were conducted with 34 health professionals, including physicians, physician assistants, nurses, nurse practitioners, health educators and dietitians. Interviews were transcribed, coded and analyzed based on participants' respective occupations. This paper focuses on how a subset of these professionals, health educators and dietitians, convey breast cancer risk information to African American women, and how they address environmental risk factors with this group. In addition, factors that influenced or hindered their sharing of breast cancer risk information were explored.

description: The photo-dissociation of H$_2$ by a nearby anisotropic source of radiation is seen as a critical component in creating an environment in which a direct collapse black hole may form. Employing radiative transfer we model the effect of multi-frequency (0.76 eV - 60 eV) radiation on a collapsing halo at high redshift. We vary both the shape of the spectrum which emits the radiation and the distance to the emitting galaxy. We use blackbody spectra with temperatures of $\rm{T = 10^4\ K}$ and $\rm{T = 10^5\ K}$ and a realistic stellar spectrum. We find that an optimal zone exists between 1 kpc and 4 kpc from the emitting galaxy. If the halo resides too close to the emitting galaxy the photo-ionising radiation creates a large HII region which effectively disrupts the collapsing halo, too far from the source and the radiation flux drops below the level of the expected background and the H$_2$ fraction remains too high. When the emitting galaxy is initially placed between 1 kpc and 2 kpc from the collapsing halo, with a spectral shape consistent with a star-forming high redshift galaxy, then a large central core forms. The mass of the central core is between 5000 and 10000 $\rm{M_{\odot}}$ at a temperature of approximately 1000 K. This core is however surrounded by a reservoir of hotter gas at approximately 8000 K which leads to mass inflow rates of the order of $\sim 0.1$ $\rm{M_{\odot}}$ yr$^{-1}$. This environment has the potential to form a massive primordial star which can then lead to the formation of a direct collapse black hole.

Characterization of Ionic Copper and Zinc as Disinfectants in Drinking Water
Creators: name: Malone, Alyson

description: In order to characterize the combined ionic copper and zinc metals as potential point of use drinking water disinfectants, inactivation kinetics were examined for three microorganisms: 1) Bacillus cereus, a sporulating bacteria indicator of encysted parasites, 2) Escherichia coli, a bacterial indicator of fecal contamination, and 3) MS2, an enteric indicator virus. Experiments were conducted using two sorts of laboratory buffered water with and without organic content at pH 7.2±0.3 pH units. Disinfectant concentrations were at the levels of 0.2 and 2.0 mg/L representing 10% and 100% respectively of the World Health Organization's and the United States Environmental Protection Agency's published guidelines for drinking water quality. Inactivation kinetics was determined by computing the survival ratio of organisms at measured time intervals. Bacteria and bacteriophage were assayed by enumerative culture methods, using spread plate assays for the bacteria and a plaque assay for the bacteriophage. Inductively coupled plasma mass spectrometry (ICP-MS) was used to quantify the concentration of copper and zinc metal ions both at time zero and at the conclusion of the experiment when six hours had elapsed. To compare inactivation data for the organisms in different test conditions, times to achieve a specified adequate log[10] reduction of organisms were calculated. In cases where the dataset conformed to first-order log-linear kinetics, the Chick-Watson kinetics model was used to extrapolate the times for 99% and 99.9% inactivation (2- and 3-log[10] bacteria and virus reduction). When deviations from linear kinetics were displayed by the dataset, two alternative mathematical models were used to predict the inactivation kinetics of the test organisms based on the experimental data These models were 1) the Hom model, which considers a decreasing disinfectant concentration over time, and 2) the One-Hit Two-Population model, which considers two populations of microorganisms, each with a unique disinfection rate constant. The measure of fit was determined for each model using the least-squares method and a matched-pairs correlation coefficient. The results indicate that ionic copper/zinc is an adequate disinfectant for stored drinking water in a model system under controlled conditions at several dose/microorganism combinations in both synthetic and natural organic matter (NOM)-amended buffered test waters. Specifically, at the lower ionic copper/zinc disinfectant dose of 0.2 mg/L, adequate disinfection was achieved for E. coli in 9 hours (in both test waters), for MS-2 in 10 hours (in synthetic test water), and for B. cereus spores in 24 hours (in NOM-amended test water). At the higher ionic copper/zinc disinfectant dose of 2 mg/L, adequate disinfection was achieved for E. coli within 6 hours (in synthetic test water), for MS-2 within 18 hours (in both test waters), and for B. cereus within 8 hours (in NOM-amended test water).

description: Recently the OPE coefficients of the 3D Ising model universality class have been calculated by studying the two-point functions perturbed from the critical point with a relevant field. We show that this method can be applied also when the perturbation is performed with a relevant field coupled to a non uniform potential acting as a trap. This setting is described by the trap size scaling ansatz, that can be combined with the general framework of the conformal perturbation in order to write down the correlators $$, $$ and $$, from which the OPE coefficients can be estimated. We find $C^σ_{σε}= 1.051(3)$ , in agreement with the results already known in the literature, and $C^ε_{εε}= 1.32 (15)$ , confirming and improving the previous estimate obtained in the uniform perturbation case.
