Slurry-Phase Biological Treatment of Tar-Contaminated Soil: Effects of Amendments on Removal of Recalcitrant Polycyclic Aromatic Hydrocarbons
Creators: name: Roy, Denise Violon
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1997

description: The primary purpose of this study was to develop, maintain, and operate slurry-phase biological reactors for treatment of soil obtained from a former manufactured gas plant (MGP) site in Greenville, SC. One of the reactors was also used to generate treated soil for preliminary testing of post-treatment strategies aimed at removing the contaminants remaining after slurry-phase treatment. Conventional slurry-phase treatment removed only a certain percentage of the low molecular weight (LMW) and high molecular weight (HMW) polycyclic aromatic hydrocarbons (PAHs) with the exception of benzo[a]pyrene, which was not removed at all. Subsequent slurry-phase treatment (longer residence times) did not increase removal rates of these recalcitrant compounds. Therefore, two additional treatment strategies were investigated. These strategies were subsequent batch treatment with a surface active agent (surfactant) and the addition of readily degradable substrates known or believed to induce the degradation of LMW PAHs. Tests were conducted to observe the rates and assess the time scale over which the surfactant Brij 30 sorbed to the soil and solubilized PAHs from the soil. The surfactant and inducing substrate amendments investigated in this study did not affect the removal rates of recalcitrant LMW or HMW PAHs; several explanations for these results are proposed and need to be investigated further.

description: Instance segmentation is the problem of detecting and delineating each distinct object of interest appearing in an image. Current instance segmentation approaches consist of ensembles of modules that are trained independently of each other, thus missing opportunities for joint learning. Here we propose a new instance segmentation paradigm consisting in an end-to-end method that learns how to segment instances sequentially. The model is based on a recurrent neural network that sequentially finds objects and their segmentations one at a time. This net is provided with a spatial memory that keeps track of what pixels have been explained and allows occlusion handling. In order to train the model we designed a principled loss function that accurately represents the properties of the instance segmentation problem. In the experiments carried out, we found that our method outperforms recent approaches on multiple person segmentation, and all state of the art approaches on the Plant Phenotyping dataset for leaf counting.

description: Tetrodotoxin (TTX) is a potent neurotoxin responsible for a human intoxication event in Spain associated with the consumption of trumpet shell Charonia lampas. In Europe, TTX is not regulated or monitored, and there is little knowledge about its presence in seafood. Here, we investigated the tissue distribution of TTX and analogues in three specimens of trumpet shell C. lampas bought in a market in southern Portugal. Toxin concentration was above the EFSA recommended limit in the non-edible tissues of all specimens and within the limit in the edible tissues of two specimens. 4,9-AnhydroTTX and 13 additional TTX analogues were detected in tissues, the most abundant being anhydrotrideoxyTTX and trideoxyTTX. These results suggest that although thorough evisceration may lower the amount of TTX consumed, it may not be sufficient to ensure consumer safety. Regular monitoring of TTX and analogues in trumpet shell and other edible gastropods is therefore recommended to avoid poisoning incidents.

Assessing Structure Activity.Relationships of Polyhalogenated Aromatic Hydrocarbons with Endometriosis as an Endpoint
Creators: name: Johnson, Krista L.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1996

description: Previous studies have shown that exposure to the environmental contaminant, 2,3,7,8-tetrachlorodibenzo-ρ-dioxin (2,3,7,8-TCDD) enhances the development of endometriotic lesions. In this study, we assessed the structure activity relationships (SARs) and mechanism(s) of endometriotic proliferation by 2,3,7,8-TCDD and related polyhalogenated aromatic hydrocarbons with ligands with varying degrees of affinity for the Ah receptor. B6C3F1 female mice were treated with 0, 1, 3, or 10 ug 2,3,7,8-tetrachlorodibenzo-ρ-dioxin/kg of body weight (bw); 3 or 30 mg 2, 4, 5, 2', 4', 5'-hexachlorobiphenyl (PCB 153)/kg bw; 100, 300, or 1000 ug 3, 4, 5, 3', 4'-pentachlorobiphenyl (PCB126)/kg of bw; 10, 30, or 100 ug 2, 3, 4, 7, 8-pentachlorodibenzofuran (4-PeCDF)/kg of bw; or 2 or 20 mg 1, 3, 6, 8-tetrachlorodibenzo-ρ-dioxin (l,3,6,8-TCDD)/kg of bw at 10 ml/kg. The animals were dosed by oral gavage a total of five times with three weeks between each dosing and terminated three weeks after the last dose. At the conclusion of sixteen weeks, endometriotic lesion diameters and weights were measured. In addition, ovaries, uterine horn, and thymus were removed from each animal. Lesions, uterine horns, and ovaries were fixed for histopathology. Livers were also excised for enzymatic analysis. Analysis of lesion diameters with the Dunnett's test revealed statistically significant results for animals treated with 1 or 3 ug 2,3,7,8-TCDD/kg bw or 100 ug 4-PeCDF/kg bw. However, animals treated with 10 ug 2,3,7,8-TCDD per kg bw did not have significantly larger lesion diameters than control animals possibly due to ovarian atrophy. Animals treated with PCB 126 showed a trend of lesions with larger mean diameters than control animals, but due to variability the increases were not statistically significant. No effect on lesion diameter was apparent in animals dosed with PCB 153 or 1,3,6,8-TCDD. Statistically significant increases in lesion diameters of animals dosed with 2,3,7,8-TCDD supports previous work stating exposure to 2,3,7,8-TCDD induces proliferation of endometriotic lesions. Because neither of the "non-dioxin-like" chemicals induced increased proliferation and both "dioxin-like" chemicals caused increased lesion diameters, the data are consistent with the hypothesis that the mechanism of increased proliferation of endometriotic lesions is Ah receptor-mediated.

description: A depth one grading $\mathfrak{g}= \mathfrak{g}^{-1}\oplus \mathfrak{g}^0 \oplus \mathfrak{g}^1 \oplus \cdots \oplus \mathfrak{g}^{\ell}$ of a finite dimensional Lie superalgebra $\mathfrak{g}$ is called nonlinear irreducible if the isotropy representation $\mathrm{ad}_{\mathfrak{g}^0}|_{\mathfrak{g}^{-1}}$ is irreducible and $\mathfrak{g}^1 \neq (0)$. An example is the full prolongation of an irreducible linear Lie superalgebra $\mathfrak{g}^0 \subset \mathfrak{gl}(\mathfrak{g}^{-1})$ of finite type with non-trivial first prolongation. We prove that a complex Lie superalgebra $\mathfrak{g}$ which admits a depth one transitive nonlinear irreducible grading is a semisimple Lie superalgebra with the socle $\mathfrak{s}\otimes Λ(\mathbb{C}^n)$, where $\mathfrak{s}$ is a simple Lie superalgebra, and we describe such gradings. The graded Lie superalgebra $\mathfrak{g}$ defines an isotropy irreducible homogeneous supermanifold $M=G/G_0$ where $G$, $G_0$ are Lie supergroups respectively associated with the Lie superalgebras $\mathfrak{g}$ and $\mathfrak{g}_0 := \bigoplus_{p\geq 0} \mathfrak{g}^p$.

description: Glycidyl fatty acid esters (GEs) are processing contaminants formed during refining steps of vegetable oils. ‘In vivo’ hydrolysis of GEs releases potentially carcinogenic and genotoxic glycidol (2,3-epoxy-1-propanol). Occurrence of GEs in vegetable oils used for infant formula manufacturing may pose a potential health concern for formula-fed infants. Refined oils are commonly used as the main fat ingredient in formula manufacturing. For this study, different infant formula products (powders, concentrates and ready-to-feed formula products) were purchased and analysed in 2015 (35 samples) and 2019 (33 samples). Seven individual GEs were analysed by LC-MS/MS via direct approach by stable isotope dilution analysis, and total bound glycidol concentrations were calculated. Concentrations of bound glycidol in reconstituted formula reached maxima of 40.3 ng/g in the 2015 samples and 31.5 ng/g in the samples collected in 2019, with respective means of 8.7 ng/g and 6.7 ng/g. The analysed bound glycidol concentrations are comparable with concentration ranges from other studies, but are higher than observed in studies from the European market. Temporal trend data show a reduction of bound glycidol concentrations in 2019. GE concentrations were compared across different manufacturers.

THE LINK BETWEEN FINANCIAL DEVELOPMENT AND ECONOMIC GROWTH IN ETHIOPIA
Creators: name: Tesfaye, Roman
Publisher: name: Zenodo
Year: 2012

description: The paper examines whether a long-run relationship between financial development and economic growth exist in Ethiopia. It employs Co-integrated Vector Autoregressive (CVAR) approach to asses how the financial sector contributes to growth. It further used the granger causality test so as to find the direction of causality between financial development and economic growth. Impulse response and variance decomposition tests are also applied so as to see the interaction between financial development and economic growth. The study utilized time-series data of Ethiopia over the period 1980-2010. The findings support the existence of a uni-directional causality from economic growth to financial development. The emperical evidence, in addition, shows the presence of positive and significant long-run relationship between financial development and economic growth and an insignificant effect in the short-run. The results of Impulse response and variance decompositions also indicate the permanent effect of financial development on economic growth. The policy implication is that long-run policies of financial development are believed to provide significant effect on economic growth.
Destruction of Indicator Organisms in Wastewater Treatment Sludge using Thermophilic Anaerobic Digestion
Creators: name: Mullennix, Robert W.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1991

description: Previous studies of thermophilic anaerobic digestion were reviewed. Batch digestion (55°C) was used to develop a thermophilic seed population from OWASA mesophilic digestion sludge. Buffering was deemed to be beneficial. A sequence of 3 digestions produced a strong, viable thermophilic population. A ratio, intermediate alkalinity to partial alkalinity, was shown to be a good measure of the important volatile acids to bicarbonate alkalinity ratio in anaerobic digestion. A continuous thermophilic anaerobic digester was operated at 10 days hydraulic residence time, at 55°C, with daily draw and feed. Operation was stable, with steady state achieved after two residence times. Volatile solids destruction was 43% and gas generated was 900 ml/g volatile solids destroyed. Fecal Coliforms and fecal streptococci were measured by the 5 tube Most Probable Number method. Fecal coliforms were reduced 5.8 logs, down to log[10]1.4. Fecal streptococci were reduced 2.75 logs down to log[10]3.19. Proposed Class A pathogen reduction requires log[10]2.00 for both indicator organisms. Therefore, the process will not meet the proposed Class A requirement based on indicator organism levels in the effluent. Additional work is needed on actual pathogen destruction using thermophilic anaerobic digestion.
Managing Event-Driven Applications in Heterogeneous Fog Infrastructures
Creators: name: Wiener, Patrick
Publisher: name: Karlsruher Institut für Technologie (KIT)
Year: 2022

description: The steady increase in digitalization propelled by the Internet of Things (IoT) has led to a deluge of generated data at unprecedented pace. Thereby, the promise to realize data-driven decision-making is a major innovation driver in a myriad of industries. Based on the widely used event processing paradigm, event-driven applications allow to analyze data in the form of event streams in order to extract relevant information in a timely manner. Most recently, graphical flow-based approaches in no-code event processing systems have been introduced to significantly lower technological entry barriers. This empowers non-technical citizen technologists to create event-driven applications comprised of multiple interconnected event-driven processing services. Still, today’s event-driven applications are focused on centralized cloud deployments that come with inevitable drawbacks, especially in the context of IoT scenarios that require fast results, are limited by the available bandwidth, or are bound by the regulations in terms of privacy and security. Despite recent advances in the area of fog computing which mitigate these shortcomings by extending the cloud and moving certain processing closer to the event source, these approaches are hardly established in existing systems. Inherent fog computing characteristics, especially the heterogeneity of resources alongside novel application management demands, particularly the aspects of geo-distribution and dynamic adaptation, pose challenges that are currently insufficiently addressed and hinder the transition to a next generation of no-code event processing systems. The contributions of this thesis enable citizen technologists to manage event-driven applications in heterogeneous fog infrastructures along the application life cycle. Therefore, an approach for a holistic application management is proposed which abstracts citizen technologists from underlying technicalities. This allows to evolve present event processing systems and advances the democratization of event-driven application management in fog computing. Individual contributions of this thesis are summarized as follows: 1. A model, manifested in a geo-distributed system architecture, to semantically describe characteristics specific to node resources, event-driven applications and their management to blend application-centric and infrastructure-centric realms. 2. Concepts for geo-distributed deployment and operation of event-driven applications alongside strategies for flexible event stream management. 3. A methodology to support the evolution of event-driven applications including methods to dynamically reconfigure, migrate and offload individual event-driven processing services at run-time. The contributions are introduced, applied and evaluated along two scenarios from the manufacturing and logistics domain.

Remediation of Coal Tar Contaminated Porous Medium Systems
Creators: name: Rylander, Seth C.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2010

description: The legacy practice of municipal gas production has led to thousands of tar contaminated subsurface systems, which have resulted from the disposal and handling practices of combustion by-products formed during gas manufacturing. These tar wastes can vary widely in composition, but they are essentially always complex mixtures that contain all of the 16 poly-nuclear aromatic hydrocarbon (PAH) priority pollutants, and lOO's of other compounds as well. Conventional physicochemical remediation methods have not proven effective for remediating such sites. In this work, a novel approach is investigated based upon alkaline flushing to mobilize the residual tar contamination using a one-dimensional column. A follow-up approach is performed with an ethanol flush to further reduce the flux of PAHs from the treated source zone. More than 50% of the tar residual was removed during the alkaline flushing. Mechanistic understanding of the effects of alkaline solution flushing on wettability and tar mobilization deserve further consideration.
Geometric Backreaction of Modified Quantum Vacua and Diffeomorphisim Covariance

Publisher: name: arXiv
Year: 2015
Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)

description: In this paper we have shown that squeezed modified quantum vacua have an effect on the background geometry by solving the semi-classical Einstein Field Equations in modified vacuum. The resultant geometry is similar to (anti) de Sitter spacetime. This geometry could explain the change of causal structure - speed of light- in such vacua without violating diffeomorphism covariance or causality.The superluminal propagation of photons in Casimir vacuum is deduced from the effective electromagnetic action in the resultant curved geometry. Singling between different vacua is shown not to violate causality as well when the geometric effect on the null rays is considered, causing a refraction of those rays when travelling between unbounded and modified vacua.

description: This paper shares lessons learned at the completion of a large multi- year project (2008-2018) to move to a next-generation digital preservation repository at Harvard Library. These final stages included activities running in parallel to migrate the metadata for millions of files, train fifty-five different units to use the new repository tools, and migrate the audio files from obsolete formats. Harvard Library’s digital preservation repository, the Digital Repository Service (DRS), holds over 69 million files and 285 TB of data from across the university. When it first launched in October 2000, it was one of the first digital preservation repositories at an academic institution. At the time it was designed, there were little- to-no digital preservation/digital library standards, best practices or tools to adopt. Planning for a next-generation DRS under the name the “DRS2 project” began in 2008, with the purpose of modernizing the DRS to take advantage of the latest technologies, standards, and practices and to provide curators, depositors, and preservation staff with significantly enhanced tools. The DRS2 project included four different types of migrations: infrastructure, metadata, file format, and repository users. It included such daunting tasks as re-architecting the entire repository; re-parsing all of the millions of files; changing the underlying data model, Archival Information Package (AIP) format, and all of the XML schemas; rewriting all of the repository metadata; retraining all of the repository users; and reformatting all of the audio deliverable files. A repository migration of this size and breadth was unprecedented in the digital preservation community, so there were few preexisting examples to learn from. By sharing the experience of this project, the authors hope that other institutions can benefit from the lessons learned during a repository migration of this magnitude. This paper provides an overview of all four migrations, but delves deepest into the results, challenges and lessons learned from the metadata migration. These lessons are applicable to preservation planning and interventions, future migrations, preventing metadata and content errors, and conducting very large projects in general. This paper was the runner up for the Best Long Paper award.

Biological Treatment of Wastewater from the Production of p-Nitrosophenol
Creators: name: McCoy, Richard P.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1990

description: The biological treatability of p-nitrosophenol wastewater was investigated using Sequencing Batch Reactors (SBRs). Two 2.5 1 SBRs were operated for more than six months and were fed both a raw waste and a synthetic feed. Removal of phenol was greater than 93% and soluble COD removal was 75% or greater. The inhibitory effects of the phenolic waste were partially overcome by increasing the number of treatment cycles per day. Significant loading rates were sustained throughout the study, the highest being achieved at two cycles per day. Loss of soluble COD by abiotic means was ruled out. The use of SBRs for treatment of p-nitrosophenol wastewaters will result in significant savings over present chemical oxidation processes.

description: We study the decay of high-Reynolds number Taylor-Couette turbulence, i.e. the turbulent flow between two coaxial rotating cylinders. To do so, the rotation of the inner cylinder (Re$_i=2 \times 10^6$, the outer cylinder is at rest) is stopped within 12 s, thus fully removing the energy input to the system. Using a combination of laser Doppler anemometry and particle image velocimetry measurements, six decay decades of the kinetic energy could be captured. First, in the absence of cylinder rotation, the flow-velocity during the decay does not develop any height dependence in contrast to the well-known Taylor vortex state. Second, the radial profile of the azimuthal velocity is found to be self-similar. Nonetheless, the decay of this wall-bounded inhomogeneous turbulent flow does not follow a strict power law as for decaying turbulent homogeneous isotropic flows, but it is faster, due to the strong viscous drag applied by the bounding walls. We theoretically describe the decay in a quantitative way by taking the effects of additional friction at the walls into account.

description: Tuning the durations of the Hamiltonian flow in Hamiltonian Monte Carlo (also called Hybrid Monte Carlo) (HMC) involves a tradeoff between computational cost and sampling quality, which is typically challenging to resolve in a satisfactory way. In this article we present and analyze a randomized HMC method (RHMC), in which these durations are i.i.d. exponential random variables whose mean is a free parameter. We focus on the small time step size limit, where the algorithm is rejection-free and the computational cost is proportional to the mean duration. In this limit, we prove that RHMC is geometrically ergodic under the same conditions that imply geometric ergodicity of the solution to underdamped Langevin equations. Moreover, in the context of a multi-dimensional Gaussian distribution, we prove that the sampling efficiency of RHMC, unlike that of constant duration HMC, behaves in a regular way. This regularity is also verified numerically in non-Gaussian target distributions. Finally we suggest variants of RHMC for which the time step size is not required to be small.

description: The behaviour of correlators at large distances plays an important role in the dynamics of quantum field theories. In many instances, correlators satisfy the so-called \textit{cluster decomposition property} (CDP), which means that they tend to zero for space-like asymptotic distances. However, under certain conditions it is possible for correlators to violate this property. In the context of quantum chromodynamics (QCD), a violation of the CDP for correlators of clusters involving coloured fields implies that the strength of the correlations between the coloured degrees of freedom in these clusters increases at large distances, which is a sufficient condition for confinement. In this paper we establish a criterion for when the CDP is violated. By applying this criterion to QCD, it turns out that certain lattice results involving the quark and gluon propagators can be interpreted as evidence that quarks and gluons are confined due to a violation of the CDP.

description: We report simultaneous transport and scanning microwave impedance microscopy to examine the correlation between transport quantization and filling of the bulk Landau levels in the quantum Hall regime in gated graphene devices. Surprisingly, a comparison of these measurements reveals that quantized transport typically occurs below the complete filling of bulk Landau levels, when the bulk is still conductive. This result points to a revised understanding of transport quantization when carriers are accumulated by gating. We discuss the implications on transport study of the quantum Hall effect in graphene and related topological states in other two-dimensional electron systems.

Characterization of Ozone Precursor Emissions from Coal Fired Power Plants and their Impacts
Creators: name: Vajjala, Kesava Anirudh
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2016

description: Ground level ozone is generated due to chemical reactions between species such as NOx and VOCs in the presence of sunlight. Coal fired power plants are known to be significant sources of NOx, VOCs, and other species. The electricity produced by coal fired power plants contributed to about 39% of the nation's energy production in 2014. Emissions from coal fired power plants will lead to increased ozone production. Emission data from 80 coal fired power plants in the eastern United States was used to analyze their impacts on ozone levels. The CAMx model was used to predict the impact on ozone concentrations when NOx emissions from these power plants were reduced. The emissions were removed or zeroed out 24 hours prior to the start of measurement. Over the majority of the domain, the model predicted that there was a decrease in hourly ozone concentrations of more than 10ppb and increases of up to 8ppb. There are 11 nonattainment areas for ozone in the eastern United States. In all these regions ozone concentrations were reduced by 1ppb to 10ppb, and increased by 1ppb to 5ppb.

description: The objective of Blue Cloud is to federate access to some data services at EU level, to ease discovery and enable cross-discipline work. The data access and discovery service covers the following infrastructures: EuroArgo: profiles of physics and biogeochemistry ICOS: carbonate system records Copernicus Marine Service: gridded fields of physics, biogeochemistry SeaDataNet: local samples of physics, chemistry, etc. EMODnet: local samples of bathymetry, chemistry, geology, physics, etc. EurOBIS: occurrences of biological organisms EuroBioImaging: microscopy images of cells ENA: nucleotide sequences of biological organisms These services cover the marine environment in its different dimensions (physics, chemistry, biogeochemistry), the biology of the organisms that live it in but the information of direct ecological relevance (e.g. composition of biological communities) is limited to EurOBIS (and some of the biology section of EMODnet). EcoTaxa provides more information in this respect: it contains occurrences of individual organisms, morphological information about them in the form of images, and can summarise those to provide ecological data tables that can be used to assess the composition of biological communities. It is focused on plankton, which is a good complement to EurOBIS/EMODnet Biology which contain more information on benthic and/or more visible organisms. The development of EcoTaxa is still very active, given that the service is quite recent, and funded by several projects concurrently. The activities in specific relation with and funded by Blue Cloud are (i) the development of some API endpoints in EcoTaxa that align with the needs of the Blue Cloud data access and discovery service, (ii) the support of Blue Cloud collaborators during the development of the interface between this API and the Blue Cloud data access and discovery service. The data pipeline hence setup will be used by Blue Cloud's demonstrators.

Determination of Respirable Mass Concentration using a High Volume Air Sampler and a Sedimentation Method for Fractionation
Creators: name: Johnson, Jeffrey
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1995

description: A preliminary study of a new method for determining respirable mass concentration is described. This method uses a high volume air sampler and subsequent fractionation of the collected mass using a particle sedimentation technique. Side-by-side comparisons of this method with cyclones were made in the field and in the laboratory. There was good agreement among the samplers in the laboratory, but poor agreement in the field. The effect of wind on the samplers' capture efficiencies is the primary hypothesized source of error among the field results.
