An Evaluation of Heat Strain Monitoring Methods for Workers In encapsulating, Impermeable Protective Clothing
Creators: name: Eley, W. David
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1987

description: Heat strain for six young, healthy, acclimatized men (mean age 26.2 yrs., weight 84.1 Kg) was measured during moderate exercise at various ambient conditions (21.5 C, 28.0 C, 31.5 C with sunshine) while wearing fully encapsulating chemical protective suits with SCBA. The total weight of the protective ensemble was 26.3 Kg. The subjects performed a total of 35 minutes (20 minutes exercise, 5 minutes rest, 15 minutes exercise) of zero grade walking on a treadmill set for 4.83 Kph (3.0 mph). The average level of energy expenditure for this exercise, determined from V(02) measurements was 383 Kcal/hr. Heart rate and mean skin temperature rose significantly as ambient temperature increased. Under the most adverse ambient conditions (31.5 C with sunshine) the mean heart rate and skin temperature were elevated 39.6 bpm and 4.1 C, respectively, over those recorded for control conditions. Significant increases in rectal temperature were not noted. A mean difference in weight loss was only observed with significance between control conditions and the most severe ambient environment (31.5 C with sunshine). The five minute recovery heart rate (SMRHR), recorded at minute 25 after 20 minutes of exercise increased significantly as ambient conditions become more adverse. The mean 5MRHR were 91.7 bpm (control), 95.8 bpm (21.5°C), 108.7 bpm (28°C), and 116.4 bpm (31.5 C with sunshine). It is concluded that wearers of impermeable protective clothing show progressive increases in heat strain as ambient temperature increase. This study indicates recovery heart rate is probably the best indicator of heat tolerance endpoints for work in encapsulating, impermeable protective clothing. Recovery heart rates are easily measured with inexpensive equipment. More study is required, however, before specific recovery heart rates can be identified as a conservative endpoint.
Modified nonlinear model of arcsin-electrodynamics
Creators: name: Kruglov, S. I.
Publisher: name: arXiv
Year: 2015
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: A new modified model of nonlinear arcsin-electrodynamics with two parameters is proposed and analyzed. We obtain the corrections to the Coulomb law. The effect of vacuum birefringence takes place when the external constant magnetic field is present. We calculate indices of refraction for two perpendicular polarizations of electromagnetic waves and estimate bounds on the parameter $γ$ from the BMV and PVLAS experiments. It is shown that the electric field of a point-like charge is finite at the origin. We calculate the finite static electric energy of point-like particles and demonstrate that the electron mass can have the pure electromagnetic nature. The symmetrical Belinfante energy-momentum tensor and dilatation current are found. We show that the dilatation symmetry and dual symmetry are broken in the model suggested. We have investigated the gauge covariant quantization of the nonlinear electrodynamics fields as well as the gauge fixing approach based on Dirac's brackets.

An Evaluation of the Information Presented in Published Articles: The Availability & Usefulness of data in Reproductive and Developmental Toxicity Risk Assessments
Creators: name: Taulbee, Stephanie M.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1996

description: The procedures for performing developmental and reproductive risk assessments have just been published by the Institute for Evaluating Health Risks. These procedures were published as guidelines and continue to be evaluated. Contained in this guidance are informational needs, some general to all toxicological risk assessment and some unique to developmental and reproductive risks. This technical report evaluates ninety-seven journal articles to assess whether the required information is contained in the articles and is in a useable form. The results show that there is a lack of detail in some articles for certain information that is necessary and useful to the risk assessor. Materials and Methods sections often lack adequate information about the parameters evaluated and the numbers of animals in the study or evaluate. Information on the analysis of the test chemical and dose formulation is more often than not incomplete or absent. One critical problem is that dose levels are sometimes presented as the concentration of the formulation and not as the delivered dose which is used by the risk assessor to compare risk levels and different study results in the results and discussion sections, there is incomplete discussion of all parameters evaluated and the relation of the results to human exposure and to assumptions made in interpreting the data in some articles. There appears to be incomplete presentation of the results for some developmental and reproductive parameters, particularly those that are not "interesting" or significant. In evaluating the results of this review, recommendations are made to authors, publishers and government regulators to promote more complete and consistent reporting of developmental and reproductive studies. The concept is to be aware of the needs of risk assessors and make a concerted effort to develop and publish data for this purpose.

Analysis of a Passive Aeration Concept to Treat Swine Waste with Dead-End, Oxygen-Permeable Membrane Tubes
Creators: name: Deng, Jing
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2015

description: The conventional method of managing swine waste using open lagoons with spray irrigation is still nearly universal in North Carolina. This project seeks to explore a new technology for anaerobic swine lagoons, that is, to apply dead-end, oxygen-permeable membrane tubes individually in lagoons, which could passively provide oxygen to further treat the anaerobically digested waste. The major advantage of such a system would be near-ideal oxygen transfer efficiency and no energy cost to supply oxygen. A membrane tube model was developed to quantify oxygen concentration gradient along the tube length and rate of oxygen mass transfer through the membrane wall. From the model, I find that oxygen concentration hardly changes along the tube, and oxygen mass transfer rate is directly related to tube parameters, especially the membrane thickness. To quantify a potential full-scale application, the lagoons at Butler Farm in Lillington, NC are used as a case study. Using waste characteristics of the anaerobically digested swine waste at Butler Farm, about 12,100 membrane tubes would be needed to meet the oxygen demand in this lagoon. Finally, membrane tube manufacture, tube supporting systems and tube maintenance issues must be considered before it can be implemented in reality.

description: We challenge the hypothesis that the ground states of a physical system whose degeneracy depends on topology must necessarily realize topological quantum order and display non-local entanglement. To this end, we introduce and study a classical rendition of the Toric Code model embedded on Riemann surfaces of different genus numbers. We find that the minimal ground state degeneracy (and those of all levels) depends on the topology of the embedding surface alone. As the ground states of this classical system may be distinguished by local measurements, a characteristic of Landau orders, this example illustrates that topological degeneracy is not a sufficient condition for topological quantum order. This conclusion is generic and, as shown, it applies to many other models. We also demonstrate that certain lattice realizations of these models, and other theories, display a ground state entropy (and those of all levels) that is "holographic", i.e., extensive in the system boundary. We find that clock and $U(1)$ gauge theories display topological (in addition to gauge) degeneracies.

description: Let (C, p_1, p_2, \ldots, p_n) be a general marked curve of genus g, and q_1, q_2, ..., q_n \in P^r be a general collection of points. We determine when there exists a nondegenerate degree d map f : C \to P^r so that f(p_i) = q_i for all i. This is a consequence of our main theorem, which states that the restricted tangent bundle f^* T_{P^r} of a general curve of genus g, equipped with a general degree d map f to P^r, satisfies the property of interpolation (i.e.\ that for a general effective divisor D of any degree on C, either H^0(f^* T_{P^r}(-D)) = 0 or H^1(f^* T_{P^r}(-D)) = 0). We also prove an analogous theorem for the twist f^* T_{P^r}(-1).

description: We construct ensembles of random integrable matrices with any prescribed number of nontrivial integrals and formulate integrable matrix theory (IMT) -- a counterpart of random matrix theory (RMT) for quantum integrable models. A type-M family of integrable matrices consists of exactly N-M independent commuting N-by-N matrices linear in a real parameter. We first develop a rotationally invariant parametrization of such matrices, previously only constructed in a preferred basis. For example, an arbitrary choice of a vector and two commuting Hermitian matrices defines a type-1 family and vice versa. Higher types similarly involve a random vector and two matrices. The basis-independent formulation allows us to derive the joint probability density for integrable matrices, in a manner similar to the construction of Gaussian ensembles in the RMT.

description: This project investigates the influence of reward on the perception of visual information. Previous studies repeatedly show that reward can capture attention even if the reward information is not behaviorally relevant or counterproductive. This indicates that the effect of reward occurs before the information reaches attention. This project explores this idea of reward's impact on early stages of brain's information-processing stream, i.e., perception.

Dynamic colour screening in diffractive deep inelastic scattering

Year: 2015
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: We present a novel Monte-Carlo implementation of dynamic colour screening via multiple exchanges of semi-soft gluons as a basic QCD mechanism to understand diffractive electron-proton scattering at the HERA collider. Based on the kinematics of individual events in the standard QCD description of deep inelastic scattering at the parton level, which at low $x$ is dominantly gluon-initiated, the probability is evaluated for additional exchanges of softer gluons resulting in an overall colour singlet exchange leading to a forward proton and a rapidity gap as the characteristic observables for diffractive scattering. The probability depends on the impact parameter of the soft exchanges and varies with the transverse size of the hard scattering subsystem and is therefore influenced by different QCD effects. We account for matrix elements and parton shower evolution either via conventional DGLAP $\log Q^2$-evolution with collinear factorisation or CCFM small-$x$ evolution with $k_\perp$-factorisation and discuss the sensitivity to the gluon density distribution in the proton and the importance of large log\,$x$-contributions. The overall result is that, with only two model parameters which have theoretically motivated values, a satisfactory description of the observed diffractive cross-section at HERA is obtained in a wide kinematical range.

The Effect of Temperature and Salinity on the Depuration of Hepatitis A Virus and Other Microbial Contaminants from Clams

Year: 1990

description: Depuration or the process of self-purification has been used for many years to reduce the enteric microbial contaminants from shellfish harvested from sewage polluted waters. Little is known however about the effectiveness of this process in eliminating enteric viral pathogens. This study compared the reduction of hepatitis A virus (HAV) to that of poliovirus 1, bacteriophage MS2, Escherichia coli, and Streptococcus faecalis, from experimentally contaminated clams (Mercenaria mercenaria). The clams were subjected standard depuration conditions in a model, laboratory-scale system. The effect of temperature (12, 18, 25°C) and salinity (8, 18, 28ppt) on virus and bacteria depuration over period of 4-5 days was studied. The viruses were not depurated as effectively as the bacteria. Elimination rates of test organisms was independent of temperature. Depuration rates were reduced at lower salinity (8 and 18ppt). The results indicate that the current the practices and conditions of depuration are ineffective in eliminating enteric viruses from clams. These studies further suggest that coliform bacteria is an inadequate indicator of virus elimination from shellfish.

Ecological Sanitation: Technical Issues on the Adequacy of On-Site Storage and Treatment of Human Waste
Creators: name: Stea, Robert G.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1999

description: A recent development in the water and sanitation sector is the concept of ecological sanitation (Eco-sanitation, or "Eco-San"); that is, the on-site storage and treatment of human fecal waste. The goal of this type of sanitation is to provide the user with a hygienic means of waste disposal, as well as a safe, stable, and useful end product. This paper examines the efficacy of such systems; namely, the type of treatment provided and the extent of pathogen destruction. Mathematical models of pathogen die-off data from experimental studies are used to estimate the hygienic quality of human fecal material under conditions normally found in Eco-San systems. A review of the literature shows major gaps in the data available to model the Eco-San systems. Lack of field data on the Eco-San process results in an incomplete description of the operating conditions. The scarcity of data on the kinetics of pathogen destruction at low temperatures also adds uncertainty to the assessment. Also, much of the available kinetic data is from studies that are carried out under conditions not necessarily encountered in Eco-San. Extrapolation of pathogen destruction from the kinetic models developed under different test conditions show inconsistent results. The use of the EPA Part503 Biosolids Rule pathogen reduction model also is not appropriate as a guide to determining treatment efficiency. More research and data on the survival of pathogens at lower temperature ranges is needed to determine the exact nature of Eco-San process efficiency. Existing data is used to develop a simplified model for the prediction of pathogen destruction. Recommendations are made to develop indicators of the efficacy of Eco-San treatment. The conclusions include a discussion on the way to operate double-vault latrines in dual phase manner that will result in a safe, hygienic end product.
Humanism, Oriental Studies, and the Birth of Philology: Learning Arabic in Europe since the Sixteenth Century
Creators: Riedel, Dagmar A.
Publisher: name: Columbia University
Year: 2006
Subjects: Islamic civilization
Islam--Customs and practices

description: I will explore the emergence of Arabic studies in western Europe between the sixteenth-century Reformation and nineteenth-century Imperialism. There is scant research on the history of Arabic studies in early modern Europe aside from Johann Fück' s Arabische Studien (1955), because previous scientific efforts in the field seemed insignificant after the pioneering work of scholars such as Antoine Silvstre de Sacy (1758–1838) and Gustav Flügel (1802–1870). Moreover, research on European Orientalism has focused on the perception of Arabs and Islam within the context of French and British Near East politics, following the lead of Edward Said' s Orientalism (1979). My starting point is the observation that the theoretical discourse of Arabic studies still appears to be largely independent of that in French, English, or Germanic studies. The continued methodological autonomy seems to reflect that neither sixteenth-century Humanists nor nineteenth-century philologists were interested in the Arabic language. While Anthony Grafton has explored how the Humanist approach to editing developed from the goal to recover the Latin and Greek heritage of antiquity, Bernard Cerquiglini has analyzed how nineteenth-century philology became the scientific methodology for editing the first literary documents written in the European vernaculars. Latin, however, was continually taught, even throughout the Dark Ages. In contrast, Thomas Erpenius (1584–1624) published the first Arabic grammar (1617), and only in the seventeenth century did European libraries begin to collect systematically Arabic literature. But the marginal position of Arabic within European university curricula is salient. During the Middle Ages Muslims and Christians competed for territory in Spain, southern Italy, Asia Minor, and the Levant, and since the Reformation, both Protestants and Catholics had relied on Islam as the prime example for spotting false prophets and Antichrists. I will use the chapter on Islam in the Cérémonies et coutumes religieuses de tous les peoples du monde by Bernard Picart (1673–1733) to examine the role of Islam in the Enlightenment discourse on idolatry. My analysis will demonstrate that religious intolerance among Christians shaped their perceptions of diverse Muslim societies from the Balkans to the Indian peninsula. I will argue that nineteenth-century Arabic studies remained distant from the modern methodological developments in the field of philology because Europeans did not encounter an Arab nation state with Arabic as its national language. Knowledge of Arabic was relevant for theological research on the Scriptures, but not for the recovery of the literary heritage of the modern national languages.

Explaining the most energetic supernovae with an inefficient jet-feedback mechanism

Subjects: subject: High Energy Astrophysical Phenomena (astro-ph.HE)

description: We suggest that the energetic radiation from core-collapse super-energetic supernovae (SESNe) is due to a long lasting accretion process onto the newly born neutron star (NS), resulting from an inefficient operation of the jet-feedback mechanism. The jets that are launched by the accreting NS or black hole (BH) maintain their axis due to a rapidly rotating pre-collapse core, and do not manage to eject core material from near the equatorial plane. The jets are able to eject material from the core along the polar directions, and reduce the gravity near the equatorial plane. The equatorial gas expands, and part of it falls back over a timescale of minutes to days to prolong the jets-launching episode. According to the model for SESNe proposed in the present paper, the principal parameter that distinguishes between the different cases of CCSN explosions, such as between normal CCSNe and SESNe, is the efficiency of the jet-feedback mechanism. This efficiency in turn depends on the pre-collapse core mass, envelope mass, core convection, and most of all on the angular momentum profile in the core. One prediction of the inefficient jet-feedback mechanism for SESNe is the formation of a slow equatorial outflow in the explosion. Typical velocity and mass of this outflow are estimated to be approximately 1000 km/s and greater than about 1 solar mass, respectively, though quantitative values will have to be checked in future hydrodynamic simulations.

description: On June 30th, 2013 a storm moved across Chapel Hill, NC causing flooding at a number of sites on the University of North Carolina at Chapel Hill campus. The Student Recreation Center (SRC) site located on campus at South Road experienced severe flooding which resulted in over $107,000 in damages. Field investigations by the UNC staff suggested a significant causative factor was mulch from the site that blocked several storm drain inlets and prevented runoff from entering the local storm pipe network. This study sought to identify all possible causes and quantify their significance. Eight technical options were developed and compared against five criteria using a combination of hydraulic modeling, technical consultations, and field observations. Two of the options, adding new inlets and soldier courses (mulch barriers), were incorporated in the recommended solution. An implementation plan was prepared, including costs which were approximately compared with costs from flood damages averted.

Fecal Coliform Pollution as a Function of Land Use and Stormwater Management Policies in North Carolina
Creators: name: Jordanova, Tania Valentinova
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2013

description: Pathogen nonpoint source (NPS) pollution is a leading cause of surface water impairment in the United States. Often, the sources of NPS pollution are difficult to ascertain. Previous studies have employed land use regression methods to develop a greater understanding of the sources of microbial NPS pollution. The results indicate that urban development and percentage of impervious surface are correlated with higher fecal coliform concentrations. In addition to the land cover and urban development variables, this study seeks to find models of fecal coliform contamination based on the spatial coverage of federal and state stormwater management policies. Such policies have not previously been included in predictive models, even though they could have an impact on water quality. Furthermore, the model we construct is on a larger, state-level geographical scale that spans multiple water sheds as opposed to the single watershed models commonly found in the literature. Nine parameters from over 30 predictor variables were selected for the final model, which has an adjusted R2 of 0.61. This model can be used to improve predictions of fecal coliform levels at unmonitored fresh water locations across North Carolina. The model also presents the first steps in examining the large-scale effects of stormwater regulations on surface water pathogen levels, though more research is needed.

description: We use Herschel 70 to 160um images to study the size of the far-infrared emitting region in about 400 local galaxies and quasar (QSO) hosts. The sample includes normal `main-sequence' star-forming galaxies, as well as infrared luminous galaxies and Palomar-Green QSOs, with different levels and structures of star formation. Assuming Gaussian spatial distribution of the far-infrared (FIR) emission, the excellent stability of the Herschel point spread function (PSF) enables us to measure sizes well below the PSF width, by subtracting widths in quadrature. We derive scalings of FIR size and surface brightness of local galaxies with FIR luminosity, with distance from the star-forming main-sequence, and with FIR color. Luminosities L_FIR ~ 10^11 L_Sun can be reached with a variety of structures spanning 2 dex in size. Ultraluminous L_FIR >~ 10^12 L_Sun galaxies far above the main-sequence inevitably have small Re_70um ~ 0.5 kpc FIR emitting regions with large surface brightness, and can be close to optically thick in the FIR on average over these regions. Compared to these local relations, first ALMA sizes for the dust emission regions in high redshift galaxies, measured at somewhat longer rest wavelengths, suggest larger sizes at the same IR luminosity. We report a remarkably tight relation with 0.15 dex scatter between FIR surface brightness and the ratio of [CII] 158um emission and FIR emission -- the so-called [CII]-deficit is more tightly linked to surface brightness than to FIR luminosity or FIR color.

Association between Personal Faith and Sexual Risk-Taking in Adolescence and Emerging Adulthood: A Systematic Review and Meta-Analysis

description: Adolescents and emerging adults are more likely to have unprotected sex and to have multiple partners compared to older adults, which puts them at a greater risk of contracting sexually transmitted infections (Panchaud, Singh, Feivelson, & Darroch, 2000). A growing body of research indicates that religion may be a protective factor for sexual risk taking in adolescence and emerging adulthood (Haglund & Fehring, 2010). However, studies that assessed the relationship between religiosity and sexual risk taking have reported mixed findings (Rostosky et al., 2004; Zimmer-Gembeck & Helfand, 2008; Boislard, van de Bongardt & Blais, 2016). These inconsistencies and conflicting findings could reflect different psychosocial mechanisms that underlie the link between sexual risk-taking behaviors on the one hand and ritualistic aspects of religiosity (i.e., formal religiosity) and more intrinsic aspects—such as personal faith and importance attached to being a religious person (Nonnemaker, McNeely, & Blum, 2003; Regnerus, 2003) on the other hand. Religious service attendance may serve as a form of social integration that increases the opportunities for social support and reinforces internalization of religious group’s norms or peer pressure from religious friends, thus reducing the possibility of risky sexual behavior. In contrast, personal faith may reflect the of internalization of religious values and rules that may affect one’s attitudes and norms on sexuality and sexual behavior. Due to the sparsity of systematic assessment and synthesis in this research field, the potential differences, and their consequences for understanding young people’s sexual risk taking remain underexplored. Following our previous meta-analysis that assessed the relationship between religious service attendance and sexual risk taking in adolescents and emerging adults (https://osf.io/swbx3), the purpose of this study is to systematically review the literature on associations between personal faith and sexual risk-taking to enable comparisons between the role of religiosity and faith in young’s people sexual risk taking.
Measurement of spin correlations in t t-bar production using the matrix element method in the muon + jets final state in pp collisions at sqrt(s) = 8 TeV
Creators: name: CMS Collaboration

Subjects: subject: High Energy Physics - Experiment (hep-ex)
subject: FOS: Physical sciences

description: The consistency of the spin correlation strength in top quark pair production with the standard model (SM) prediction is tested in the muon + jets final state. The events are selected from pp collisions, collected by the CMS detector, at a centre-of-mass energy of 8 TeV, corresponding to an integrated luminosity of 19.7 inverse femtobarns. The data are compared with the expectation for the spin correlation predicted by the SM and with the expectation of no correlation. Using a template fit method, the fraction of events that show SM spin correlations is measured to be 0.72 +/- 0.08 (stat) +0.15 -0.13 (syst), representing the most precise measurement of this quantity in the lepton + jets final state to date.

Respirable Dust Levels During Relining of Foundry Induction Furnaces
Creators: name: Buchanan, Susan K.M.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1986

description: Industrial hygiene surveys were conducted to assess employee exposures to respirable silica during induction furnace relining. The operation is performed once every 6 to 12 weeks and takes between 8 to 16 hours to complete. Survey results showed that exposures ranged between 0.87 - 19.90 mg/m3 during the process and samples contained between 40 - 65% free silica as determined by colorimetric method of analysis. The exposures which occur during the initial lining removal stage include exposures to cristobalite which is formed during furnace use. The health implications of these short-term, high exposures has not been evaluated, however, good industrial hygiene work practices suggest that exposure levels be kept to a minimum and recommendations for dust reduction have been made. Other potential hazards identified were noise created by pneumatic tools and asbestos present in the preliner fabric. Both require further evaluation to determine the extent of the exposures.
Robo-Advisers and the Suitability Requirement: How They Fit in the Regulatory Framework

description: Robo-advisers, which provide algorithmic investment advice, are becoming increasingly prevalent players in the financial services industry. As their prominence grows, regulators are working to determine where they fit in the current framework. Specifically, the Securities and Exchange Commission has been working toward setting standards for robo-advisers as they seek to provide suitable advice to investors. In November 2016, the Securities and Exchange Commission held its Fintech Forum, where regulators and industry leaders commented on the suitability requirement and how robo-advisers can meet it. This Note analyzes the current regulatory framework for robo-advisers and proposes ways that regulators can tailor the suitability requirement to digital investment advice.
