Evaluation of the Potential Health Hazards Associated with the Machining of Carbon Fiber Composites
Creators: name: Zustra, Michael A.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1987

description: Industrial hygiene surveys were conducted to assess personnel exposures to carbon fibers and carbon/epoxy composite dust during carbon composite airframe sanding operations. The operation is currently performed every two to three weeks for eight hours at a time. The nature and frequency of operation performance is expected to change as more composite aircraft are put into service. Survey results showed that actual exposures ranged from 0-<.07 fibers/cc for carbon fibers and 1.25 mg/m3 to 2.81 mg/m3 for total composite dust. Chamber sampling of "worst case" exposures ranged from 0-.5 fibers/cc for fibers and 31.9 mg/m3 to 96.62 mg/m3 for total dust. The health implications of carbon composite particulate exposure are not well understood. Good industrial hygiene practices, however, suggest that exposure levels be kept to a minimum. Recommendations for reducing personnel exposure have been made. To characterize the composite debris, a particle size distribution and fiber dimension analyses were done. Additionally, several organizational standards relating to carbon composite particulates were evaluated. A recommendation for reducing the applicable Coast Guard standards has been made. Other potential hazards identified were exposure to solvents during lay-up procedures, and to primer dust during sanding work. Both require further evaluation to determine the extent of the exposure.

Radiation-driven outflows from and radiative support in dusty tori of active galactic nuclei

Subjects: subject: Astrophysics of Galaxies (astro-ph.GA)
subject: FOS: Physical sciences

description: Substantial evidence points to dusty, geometrically thick tori obscuring the central engines of active galactic nuclei (AGNs), but so far no mechanism satisfactorily explains why cool dust in the torus remains in a puffy geometry. Near-Eddington infrared (IR) and ultraviolet (UV) luminosities coupled with high dust opacities at these frequencies suggest that radiation pressure on dust can play a significant role in shaping the torus. To explore the possible effects of radiation pressure, we perform three-dimensional radiative hydrodynamics simulations of an initially smooth torus. Our code solves the hydrodynamics equations, the time-dependent multi-angle group IR radiative transfer (RT) equation, and the time-independent UV RT equation. We find a highly dynamic situation. IR radiation is anisotropic, leaving primarily through the central hole. The torus inner surface exhibits a break in axisymmetry under the influence of radiation and differential rotation; clumping follows. In addition, UV radiation pressure on dust launches a strong wind along the inner surface; when scaled to realistic AGN parameters, this outflow travels at $\sim 5000 (M/10^7 M_\odot)^{1/4} [L_\mathrm{UV}/(0.1 L_\mathrm E)]^{1/4} \mathrm{km}\,\mathrm s^{-1}$ and carries $\sim 0.1 (M/10^7 M_\odot)^{3/4} [L_\mathrm{UV}/(0.1 L_\mathrm E)]^{3/4} M_\odot\,\mathrm{yr}^{-1}$, where $M$, $L_\mathrm{UV}$, and $L_\mathrm E$ are the mass, UV luminosity, and Eddington luminosity of the central object respectively.

Alternating Anaerobic and Aerobic Reactors in Series for Biological Nutrient Removal - Treatability Study for Durham County Triangle Wastewater Treatment Plant
Creators: name: Frisher, Tom R.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1992

description: The Durham County Triangle Wastewater Treatment Plant faces new wastewater effluent restrictions with the renewal of the plant's National Pollutant Discharge Elimination System (NPDES) permit. The North Carolina Department of Environment, Health and Natural Resources, Division of Environmental Management (NCDEM), that administers the enforcement of NPDES in North Carolina, imposed more stringent effluent requirements on five-day biochemical oxygen demand (BOD5), ammonia nitrogen (NH3-N), total phosphorus (TP), fecal coliform, residual chlorine and dissolved oxygen (DO). The new effluent TP restrictions, along with recent prohibition of wastewater sludge wasting into landfills in North Carolina and potential agricultural application of waste sludge, motivated Durham County to investigate additional nutrient removal alternatives. The Biological Nutrient Removal (BNR) approach, in contrast to chemical removal of phosphorus, demonstrates potential for lowering operation and maintenance costs and reducing sludge production. Also, BNR proves more suitable for land application of sludge because it does not employ potentially harmful chemicals. This report describes a laboratory investigation of the feasibility of physical, operational and hydraulic modifications to the extended aeration basins of the Triangle Wastewater Treatment Plant for enhanced biological phosphorus removal, nitrification and denitrification, combined with effective carbonaceous oxidation. The Durham County Engineering Office funded this project to investigate the feasibility of using BNR technology at the Durham County Triangle WWTP. The focus of the study is the conversion of the existing extended aeration tanks to alternating anaerobic and aerobic sections for the purpose of facilitating BNR.

Stable-Isotope Probing of Anthracene-Degrading Bacteria in a Bioreactor Treating Polycyclic Aromatic Hydrocarbon-Contaminated Soil
Creators: name: Dunlevy, Sage
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2012

description: In a prior study examining the degradation of anthracene in untreated soil from a former manufactured-gas plant (MGP), an α-Proteobacterium designated "anthracene group 1" (AG1) was identified as the dominant bacterial anthracene degrader based on recovered 16S rRNA gene sequences during stable-isotope probing (SIP). However, quantitative real-time PCR analysis of AGl 16S rRNA genes of the same soil treated in a lab-scale, slurry-phase bioreactor indicated that these organisms were not likely the primary degraders of anthracene after biological treatment. This study used SIP with [U-^13C] anthracene to identify 168 rRNA genes associated with bacteria responsible for anthracene degradation in bioreactor-treated soil. Three bacterial groups were identified as anthracene degraders. One was closely related to members of the genus Altererythrobacter and two others were similar to bacteria within the order Rhizobiales. Members of the genus Altererythrobacter have been previously linked with PAH degradation but usually in a marine environment. Rhizobiales have been previously linked with both low- and high-molecular weight PAH degradation. These results suggest that conditions in a bioreactor can enrich for organisms capable of degrading a particular contaminant that are not the same organisms identified as dominant degraders of that contaminant in the untreated soil.
Giant Anomalous Hall Effect in the Chiral Antiferromagnet Mn3Ge

description: The external field control of antiferromagnetism is a significant subject both for basic science and technological applications. As a useful macroscopic response to detect magnetic states, the anomalous Hall effect (AHE) is known for ferromagnets, but it has never been observed in antiferromagnets until the recent discovery in Mn3Sn. Here we report another example of the AHE in a related antiferromagnet, namely, in the hexagonal chiral antiferromagnet Mn3Ge. Our single-crystal study reveals that Mn3Ge exhibits a giant anomalous Hall conductivity $|σ_{xz}|$ ~ 60 per ohm per cm at room temperature and approximately 380 per ohm per cm at 5 K in zero field, reaching nearly half of the value expected for the quantum Hall effect per atomic layer with Chern number of unity. Our detailed analyses on the anisotropic Hall conductivity indicate that in comparison with the in-plane-field components $|σ_{xz}|$ and $|σ_{zy}|$, which are very large and nearly comparable in size, we find $|σ_{yx}|$ obtained in the field along the c axis is found to be much smaller. The anomalous Hall effect shows a sign reversal with the rotation of a small magnetic field less than 0.1 T. The soft response of the AHE to magnetic field should be useful for applications, for example, to develop switching and memory devices based on antiferromagnets.
Evaluation of a Carbon Sorption Method for Sampling Gasoline Vapors in the Subsurface
Creators: name: Wallingford, Edward D.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1987

description: Monitoring of contaminant vapors in the unsaturated zone is a convenient method for detecting volatile organic contaminants in the subsurface. This technique can be used for optimizing the placement of monitoring and recovery wells. The most common method uses a driveable ground probe (DGP) to extract vapor sample followed by direct injection into a portable gas chromatograph (GC). However, many regional offices of regulatory agencies do not have ready access to such equipment. This research evaluates an alternative method- the carbon adsorption method- in which vapor is withdrawn by the DGP but concentrated on a small activated carbon trap (150 mg). The carbon traps can be returned to a central laboratory for solvent extraction and GC analysis. This provides the advantage of a reduction in field equipment and convenience of in-lab analyses (multiple GC injections are possible) and also increased sensitivity because any volume of soil vapor may be collected. A simple DGP and carbon trap system was constructed and tested at a field site. Soil vapor concentrations of target compounds present in gasoline were conveniently mapped; the concentrations ranging from 10,000 ug/liter of soil vapor to less than 10 ug/L. These concentrations were also shown to to decrease in the direction of the ground surface as expected. Measurements of target compounds in soil indicated that the soil vapor contributed a large fraction of the total contaminant mass where a non aqueous phase layer (NAPL) had been identified. As important is the rather uniform contamination of soil outside the NAPL region. Finally, the concentrations of target compounds in the soil vapor and ground water could be related in a manner roughly described by a simple equilibrium model, although exceptions were noted.

Performance Testing of Carbon Adsorption Diffusion Barrier Canisters

description: Radon is a naturally occurring, radioactive, inert gas that is one of the nuclides emitted in the uranium-238 (238U) radioactive decay series. Upon its decay, radon produces additional radioactive elements which are referred to as radon progeny. Present throughout the environment, radon-222 (222Rn) accounts for 55% of the total radiation dose to the United States population. Concern has grown over the effects of 222Rn exposures because of the increased lung cancer potential from breathing radon contaminated air in enclosed living and working spaces. Radon gas emanates from soils containing uranium deposits. If the soil under a house, or surrounding the basement of a house, contains uranium deposits, the escaping radon gas may become trapped in houses whose foundations are set in or on the soil. The concentration of radon in a building depends on the presence of uranium in the soil at that location, the ability of the radon to seep through the soil, and the entry routes of radon into the house from the soil. Radon-222 is emitted from the natural decay of radium-226 (226 Ra) which is part of the 238U decay series. The emission of radon is represented by the decay chain shown in Figure 1 beginning with 226Ra. Radon-222 and its progeny, polonium-218 (218 Po) and polonium-214 (214 Po) are alpha particle emmitters. The alpha emissions are responsible for the majority of the lung doses resulting from the inhalation of 222Rn and its progeny.

description: We present a new general relativistic magnetohydrodynamics (GRMHD) code integrated into the Athena++ framework. Improving upon the techniques used in most GRMHD codes, ours allows the use of advanced, less diffusive Riemann solvers, in particular HLLC and HLLD. We also employ a staggered-mesh constrained transport algorithm suited for curvilinear coordinate systems in order to maintain the divergence-free constraint of the magnetic field. Our code is designed to work with arbitrary stationary spacetimes in one, two, or three dimensions, and we demonstrate its reliability in a number of tests. We also report on its promising performance and scalability.

description: The effect of dilution water on the health of C. dubia and reproducibility of the Mini Chronic Pass/Fail Ceriodaohnia Effluent Toxicity Test was investigated. Three tests were done: an Initial Screening Test to evaluate rapidly a variety of dilution waters, a Long-Term Culturing Experiment to evaluate long-term survival and reproduction in dilution waters passing the Initial Screening Test, and a Sodium Chloride Antagonist Experiment to evaluate the relative sensitivity of C. dubia to toxicants when cultured in different dilution waters. Levels of survival and reproduction were acceptable for C. dubia cultured in Botany Pond water (a natural surface water), 10% Perrier[TM] solution, 20% Perrier[TM] Solution, and Reconstituted Water. Levels of survival and reproduction were not acceptable for c. dubia cultured In MS Animal Media. The addition of selenium to 10% Perrier[TM] solution did not affect survival or reproduction.

description: If dark matter inhabits an expanded "hidden sector", annihilations may proceed through sequential decays or multi-body final states. We map out the potential signals and current constraints on such a framework in indirect searches, using a model-independent setup based on multi-step hierarchical cascade decays. While remaining agnostic to the details of the hidden sector model, our framework captures the generic broadening of the spectrum of secondary particles (photons, neutrinos, e+e- and antiprotons) relative to the case of direct annihilation to Standard Model particles. We explore how indirect constraints on dark matter annihilation limit the parameter space for such cascade/multi-particle decays. We investigate limits from the cosmic microwave background by Planck, the Fermi measurement of photons from the dwarf galaxies, and positron data from AMS-02. The presence of a hidden sector can change the constraints on the dark matter annihilation cross section by up to an order of magnitude in either direction (although the effect can be much smaller). We find that generally the bound from the Fermi dwarfs is most constraining for annihilations to photon-rich final states, while AMS-02 is most constraining for electron and muon final states; however in certain instances the CMB bounds overtake both, due to their approximate independence of the details of the hidden sector cascade. We provide the full set of cascade spectra considered here as publicly available code with examples at http://web.mit.edu/lns/research/CascadeSpectra.html.

Methods for Surveillance of Antimicrobial Resistant Bacteria in Environmental Water and Wastewater
Creators: name: Brown, Katy M.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2016

description: The rise of antibiotic resistant bacteria (ARB) exacerbates the global spread and burden of infectious disease. There are no harmonized efforts for ARB surveillance and response. This study investigated the development of a culture-based indicator system for the direct detection and quantification of Extended-spectrum-β-lactamase (ESBL) and carbapenemase (KPC) producing Enterobacteriaceae in exposure-relevant environmental sites including hospital and domestic sewage, treated effluent, and surface waters. This was done by performing parallel assays using agar media supplemented with antibiotics, then analyzing the clinical media’s performances via concentrations and proportions of ESBL-and KPC-producing target organisms found at all sample sites, and then confirming resistance profiles and identities of resulting isolates. The performance of the clinical medium was comparable to the gold standard for detection indicator organisms in all samples, excepting E. coli in raw sewage and surface waters. This indicator system shows promise, but more work must be done towards its iterative improvement.

description: Bias and stigmas in healthcare have been a hot topic over the past couple of years. Diversity and inclusion boards have popped up at nearly every academic institution and hospital. Race, gender, sexuality, and disabilities have been at the center of every conversation. However, one of the most prevalent and critical stigmas remains unaddressed. The lack of scrutiny regarding this tangible bias is a missed opportunity for truly improving healthcare in Appalachia. Stigmas in healthcare shape the access and quality of care patients receive. Opioid use stigma is a complex concept that further perpetuates the opioid epidemic. To improve this disparity, it is essential to examine the literature and understand the evidence provided by these studies. Unfortunately, research on the relationship between opioid use disorder and provider stigma is greatly lacking which has created the need for this in-depth analysis. Researchers will investigate the evidence available in the peer-reviewed literature in order to better understand the ways provider bias manifests into enacted stigma in Appalachia. We are particularly interested on research in Central Appalachia (Tennessee, Kentucky, West Virginia, and Virginia), as the region is a hub for the opioid epidemic. The objective of this scoping review is to call attention to the egregious disparities in healthcare affecting those with opioid use disorder.
Revisiting the distance duality relation using a non-parametric regression method

description: The interdependence of luminosity distance, $D_L$ and angular diameter distance, $D_A$ given by the distance duality relation (DDR) is very significant in observational cosmology. It is very closely tied with the temperature- redshift relation of Cosmic Microwave Background (CMB) radiation. Any deviation from $η(z)\equiv \frac{D_L}{D_A (1+z)^2} =1$ indicates a possible emergence of new physics. Our aim in this work is to check the consistency of these relations using a non-parametric regression method namely, LOESS with SIMEX. This technique avoids dependency on the cosmological model and works with a minimal set of assumptions. Further, to analyze the efficiency of the methodology, we simulate a dataset of $200$ points of $η(z)$ data based on a phenomenological model $η(z)= (1+z)^ε$. The error on the simulated data points is obtained by using the temperature of CMB radiation at various redshifts. For testing the distance duality relation, we use the JLA SNe Ia data for luminosity distances, while the angular diameter distances are obtained from radio galaxies datasets. Since the DDR is linked with CMB temperature - redshift relation, therefore we also use the CMB temperature data to reconstruct $η(z)$. It is important to note that with CMB data, we are able to study the evolution of DDR up to a very high redshift $ z = 2.418$. In this analysis, we find no evidence of deviation from $η=1$ within a $1σ$ region in the entire redshift range used in this analysis ($0 < z \leq 2.418$).

Thermoplastic foams are not adaptable to batch mixing operations nor to on-site (in situ) placement. The major commercial types of thermoplastic foams are polystyrene, poly(vinyl chloride) and cellulose acetate; other well known commercial thermoplastic foams are based on polyethylene, polypropylene and ABS. The most widely used is polystyrene, which is available as two main types: extruded foam and moulded bead foam. The thermoplastic foams are used primarily as thermal insulation. They are also used in flotation applications and in the packaging field.

description: In this paper, we consider the elliptic collinear solutions of the classical $n$-body problem, where the $n$ bodies always stay on a straight line, and each of them moves on its own elliptic orbit with the same eccentricity. Such a motion is called an elliptic Euler-Moulton collinear solution. Here we prove that the corresponding linearized Hamiltonian system at such an elliptic Euler-Moulton collinear solution of $n$-bodies splits into $(n-1)$ independent linear Hamiltonian systems, the first one is the linearized Hamiltonian system of the Kepler $2$-body problem at Kepler elliptic orbit, and each of the other $(n-2)$ systems is the essential part of the linearized Hamiltonian system at an elliptic Euler collinear solution of a $3$-body problem whose mass parameter is modified. Then the linear stability of such a solution in the $n$-body problem is reduced to those of the corresponding elliptic Euler collinear solutions of the $3$-body problems, which for example then can be further understood using numerical results of Martinéz, Samà and Simó in \cite{MSS1} and \cite{MSS2} on $3$-body Euler solutions in 2004-2006. As an example, we carry out the detailed derivation of the linear stability for an elliptic Euler-Moulton solution of the $4$-body problem with two small masses in the middle.

Assessment of Doses for the Ingestion of H-3, C-14 and P-32 using Liquid Scintillation Urinalysis
Creators: name: Hodges, Sandra McDaniel
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1993

description: The bioassay program at The National Institute of Environmental Health Sciences (NIEHS) was evaluated to insure compliance with the revised Title 10 Code of Federal Regulations Part 20 (10 CFR 20). Of particular interest were the 10 CFR 20 revisions that require a prospective dose assessment for radiation workers who are not monitored and the potential need to measure the dose to a gravid woman at a level of 6 mrem/month. Measures were taken to reduce the minimal detectable activity (MDA) for the liquid scintillation urinalysis of H-3, C-14 and P-32. Included was the comparison of three liquid scintillation (LS) cocktails to determine the optimum scintillation material based on quenching characteristics and background count rate. In addition, a suitable control material was selected and the volume of LS cocktail was optimized. The MDA was determined for each of the radionuclides and the committed effective dose equivalent (CEDE) corresponding to the urinary excretion of the MDA was calculated using data from three sources. Based on the determination of the MDA and the calculated CEDE's, the bioassay program at NIEHS was found to be capable of monitoring radiation workers for internal contamination within the exposure limits published in the revised 10CFR20. In addition, data from this research can be used as part of a prospective dose assessment for radiation workers who are not likely to receive intakes greater than 10% of the applicable ALI and who are not monitored.

description: Elucidating the nature of the magnetism of a high-temperature superconductor is crucial for establishing its pairing mechanism. The parent compounds of the cuprate and iron-pnictide superconductors exhibit Néel and stripe magnetic order, respectively. However, FeSe, the structurally simplest iron-based superconductor, shows nematic order (Ts = 90 K), but not magnetic order in the parent phase, and its magnetic ground state is intensely debated. Here, we report inelastic neutron-scattering experiments that reveal both stripe and Néel spin fluctuations over a wide energy range at 110 K. On entering the nematic phase, a substantial amount of spectral weight is transferred from the Néel to the stripe spin fluctuations. Moreover, the total fluctuating magnetic moment of FeSe is ~ 60% larger than that in the iron pnictide BaFe2As2. Our results suggest that FeSe is a novel S = 1 nematic quantum-disordered paramagnet interpolating between the Néel and stripe magnetic instabilities.

A Simulation Model to Manage the Edwards Aquifer
Creators: name: Eskaf, Shadi S.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2003

description: The Edwards Aquifer is located in south central Texas and serves as the sole source of water to the region, which includes the City of San Antonio. Recent declines in spring flows fed by the aquifer that water the habitat of several endangered species triggered a court ruling that led to the issuance of ground water pumping permits for the Edwards Aquifer in the late 1990's. If the level in a monitor well drops below a certain elevation, municipal and industrial users of the aquifer are cut back a proportion of their monthly allocation until the water level rises above the trigger elevation. This project provides a framework for analyzing short-term alternatives for obtaining temporary pumping permits to assist the San Antonio Water System municipality (SAWS) in countering possible cutbacks. In this report, a hydrologic simulation model is developed to predict the monthly aquifer levels into the future. The probabilities of encountering cutbacks of different quantities in the short-term are determined from the simulation results and are used to calculate the non-pecuniary expected costs of shortfalls in meeting demands. This project follows a policy of minimizing the total expected cost to SAWS for any scenario; that is, the sum of non-pecuniary expected costs of shortfalls plus pecuniary costs of obtaining temporary water rights. Based on any aquifer level in December, the total expected costs during the next twelve months of 1) doing nothing, 2) leasing, and 3) optioning water are compared to determine the most appropriate course of action for SAWS to cover possible cutbacks in its withdrawals from the Edwards Aquifer.
