description: We compute the conformal blocks associated with scalar-scalar-fermion-fermion 4-point functions in 3D CFTs. Together with the known scalar conformal blocks, our result completes the task of determining the so-called `seed blocks' in three dimensions. Conformal blocks associated with 4-point functions of operators with arbitrary spins can now be determined from these seed blocks by using known differential operators.

subject: fun
subject: systematic review

description: The word “fun” is in common parlance for the general public, academia, policy-makers and businesses. Many industries, public services, and interventions rely on the motivational aspects of fun to sell products, motivate students, or encourage behaviours. However, the experience of fun is understudied and there is no agreed definition nor general theory. This systematic review follows PRISMA guidelines to collate and synthesise literature regarding the topic of fun, aiming to produce a general theory and reliable definition.

Evaluation of Water Allocation Policies in China's Yellow River Basin
Creators: name: Nebiker, Steven R.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1995

description: The goal of this study was to examine the consequences of surface-water allocation policies in the Yellow River basin. This goal was accomplished using a mathematical optimization model developed by the World Bank. The first objective was to assess the economic efficiency of the upper limits on the use of river water for irrigation and other purposes as established by the Chinese government. These limits were determined to be overly restrictive for some regions, resulting in significant economic losses unless revised to reflect the optimal uses of water. The second objective was to examine the economic implications of the current 'first come, first serve' water allocation policy. Results from model simulations suggest that water should be reallocated from upstream regions to lower regions in the basin in order to maximize the value added from water use. The third objective was to estimate the economic consequences of requiring farmers to pay fees based on the marginal costs of producing irrigation water in place of current fees, which are much lower. Results indicate that farmer income in the upper and middle reaches of the river would decline substantially if marginal cost pricing were introduced, and that the government's goal of regional self-sufficiency in food production might be jeopardized. The fourth objective was to estimate the economically efficient water prices that municipal and industrial (M&I) consumers should pay to maintain projected levels of consumption. Results show that current fees should more than double to reflect the foregone economic value to other water uses. Further, as with hydropower, the M&I sector would benefit significantly if irrigators were required to pay fees reflecting the marginal costs of water production.

Investigation of Mutagenicity Due to Compounds Other than MX in Chlorinated Humic and Drinking Water
Creators: name: Singh, Ravinder
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1989

description: 3-Chloro-4-(dichloromethyl)-5-hydroxy-2(5H)-furanone, i.e MX, is recognized as a principal mutagen contributing to (on an average) 30% of the mutagenicity of chlorinated drinking water in the Ames assay. Compounds with structural similarities to MX were suggested as probable mutagens which could account for the remaining 70% of the mutagenicity of chlorinated water. The theoretical basis for the formation and activity of these MX analogues was discussed. Three such candidate mutagens, red-MX, ox-MX and ox-EMX were synthesized, and their mutagenic activities determined (in the Ames assay, strain TA 100) to be 0.13 net revs./ng; 0.36 net revs./ng and 0.03 net revs./ng respectively. It would appear that the aldehyde group is a critical structural feature that governs the mutagenicity of MX. The concentration of MX in samples of chlorinated fulvic acids, humic and drinking water was determined. MX accounted for 36%, 32% and 17% of the overall mutagenicity of these samples, respectively. SIM mode GC/MS analyses on derivatized and underivatized extracts of the chlorinated waters revealed that red-MX and ox-MX were present in concentrations equal to or slightly greater than the amount of MX, while the concentration of ox-EMX was about 20-40 times higher. Due to their weak mutagenicities however, all three compounds were found to account for (individually) less than 1% of the overall activity in each sample. Mutagenicity-directed HPLC fractionation was performed on a chlorinated solution of fulvic acids, selected because it was highly mutagenic but contained a low amount of MX (72% non-MX mutagenicity), After the second level of separation, all the activity had concentrated into a single sub-fraction (31 000 net revs./liter) which was free of MX. The responsible mutagens seem to be less polar compounds in comparison to MX.

Metals as Potential Biomarkers of Exposure to Carbon Disulfide
Creators: name: Parham, Alan G.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2001

description: Previous studies have hypothesized that Carbon Disulfide (CS2) toxicity is based on the chelation of copper and zinc ions by the dithiocarbamate derivatives arising from the reaction of CS2 with amines. The primary objective of this study was to investigate the potential involvement of trace metals in the metabolism of CS2 in exposed rats. CS2 was administered in air at 0, 50, 150, or 500 ppm to separate groups of 60 young adult male Sprague-Dawley rats for 6 hr/day, 5 days/wk, for 6.5 months. The diet consisted of NIH 07 pellets (Ziegler Brothers, Gardner, PA) and tap water from bottles. After the rats had been exposed to CS2 for 6.5 months, exposure was discontinued. Nine rats from each exposure group including controls were chosen randomly. Cumulative voided urine was collected during 0-8, 8-16, 16-24, and 24-48 hours following the last CS2 exposure. Thirty-seven metals were measured in the urine by inductively coupled plasma atomic emission spectroscopy (ICP-AES). Linear regression analysis using creatinine normalized concentrations for each exposure group over time revealed statistically significant (p<0.05) correlation coefficients for B, Ca, I, Mg, P, Pt, and Sr in the control group; Ca, I, Mg, Mn, and P in the 50 ppm group; Se and Si in the 150 ppm group; and B, Ca, Mg, Mn, and P in the 500 ppm group. With the exception of Pt, Se, and Si, the metal concentrations were decreasing over time. Linear regression analysis using total metal (μg) per time period instead of creatinine normalized (μg/mg) concentrations, yielded similar results. Since the majority of metals with a significant correlation coefficient in both analysis were in the non-exposed group, it is unlikely that the variations were a result of CS2 exposure. Future studies should concentrate on determining the natural fluctuations of urinary excretion of trace metals in rats.

Σκοπός: Μελέτη επίδρασης ιστολογικής χοριοαμνιονίτιδας στην συχνότητα εμφάνισης ενδοκοιλιακής αιμορραγίας και την περικοιλιακήςλευκομαλάκυνσης σενεογνά με ΔΚ<32εβδομάδων. Μέθοδος: Αναδρομική, μονοκεντρική μελέτη κοόρτης για το χρονικό διάστημα 2020-2021 σε νεογνά με ΔΚ <εβδομάδων, χωρισμένα σε δυο ομάδες: νεογνά μητέρων με και χωρίς ιστολογική χοριοαμνιονίτιδα. Αποτελέσματα: Σε δείγμα 91 νεογνών με μέση ΔΚ 29.1(±2.2) εβδομάδες, τα 49 νεογνά (54%) εμφάνισε ιστολογική χοριοαμνιονίτιδα του πλακούντα και 42 (46%) όχι. Από τα 91 νεογνά, 9 (10%) εμφάνισαν σοβαρή ενδοκοιλιακή αιμορραγία (III-IV), εκ των οποίων τα 7 προέρχονταν από κυήσεις της ομάδα της κλινικής χοριοαμνιονίτιδας (p=0.161). Νεογνά μητέρων με ιστολογική χοριοαμνιονίτιδα είχαν περίπου 7 φορές μεγαλύτερη συχνότητα εμφάνισης σοβαρής ενδοκοιλιακής αιμορραγίας σε σύγκριση με νεογνά μητέρων χωρίς ιστολογική χοριοαμνιονίτιδα. Μόνο 1/91 νεογνά εμφάνισε περικοιλιακή λευκομαλάκυνση. Συμπεράσματα: Σε πρόωρα νεογνά <32 εβδομάδων κύησης, η ιστολογική χοριοαμνιονίτιδα αυξάνει την πιθανότητα εμφάνισης σοβαρής ενδοκοιλιακής αιμορραγίας. Στην παρούσα μελέτη δεν αναδείχτηκε επίδραση της χοριοαμνιονίτιδας στην περικοιλιακή λευκομαλάκυνση.
description: Introduction: Chorioamnionitis is a major cause of prematurity and is believed to be associated with short-term and long-term complications in the newborn. Purpose: Study of the effect of histological chorioamnionitis on the incidence of intraventricular hemorrhage and periventricular leukomalacia in neonates with GA <32 weeks. Material-method: Retrospective single-center cohort study for the period 2020-2021 in newborns with gestational age <32 weeks, divided into two groups: newborns of mothers with and without histological chorioamnionitis. Results: In a sample of 91 newborns with mean gestational age 29.1(±2.2) weeks, 49 newborns (54%) were exposed to chorioamnionitis during pregnancy, while 42 (46%) not. Of the 91 neonates, 9 (10%) had severe intraventricular hemorrhage (III-IV), of whom, 7 were exposed to chorioamnionitis during pregnancy (p=0.161). Newborns of mothers with histologic chorioamnionitis have an approximately 7-fold increased incidence of severe intraventricular hemorrhage compared to newborns of mothers without histologic chorioamnionitis. Only 1/91 neonate developed periventricular leukomalacia. Conclusion: In preterm infants <32 weeks, histological chorioamnionitis of the placenta increases the risk of severe intraventricular hemorrhage.In the present study, no effect of chorioamnionitis on periventricular leukomalacia was shown.

description: We calculate the nonsymmetrized current noise in a quantum dot connected to two reservoirs by using the non-equilibrium Green function technique. We show that both the current auto-correlator (inside a single reservoir) and the current cross-correlator (between the two reservoirs) are expressed in terms of transmission amplitude and coefficient through the barriers. We identify the different energy-transfer processes involved in each contribution to the auto-correlator, and we highlight the fact that when there are several physical processes, the contribution results from a coherent superposition of scattering paths. Varying the gate and bias voltages, we discuss the profile of the differential Fano factor in light of recent experiments, and we identify the conditions for having a distinct value for the auto-correlator in the left and right reservoirs.

description: Qu'est-ce que la radiation? Quelle partie de la radiation intervient dans les problèmes de durabilité? Comment affecte-t-elle les matériaux organiques utilisés à l'intérieur et à l'extérieur des bâtiments? La lumière ultraviolette comprise entre 350 et 300 nm représente la radiation la plus destructrice. Elle agit en modifiant la structure chimique des polymères utilisés comme matériaux organiques de construction et affecte ainsi leurs propriétés physiques. Les UV destructeurs ne constituent heureusement qu'une faible partie de la radiation solaire totale; leur action est en outre réduite lorsque l'angle des rayons solaires décroît, et lorsque des nuages ou de la fumée forment écran. Une quantité d'UV suffisante pour dégrader les matériaux atteint malheureusement les surfaces des bâtiments; ses effets sont particulièrement nuisibles lorsqu' elle agit en conjonction avec l'oxygène, l'eau, la chaleur, ou une combinaison de ces éléments.

description: We consider the inflationary model in which the inflaton $ϕ$ couples to another scalar field $χ$ via the interaction $g^2(ϕ-ϕ_0)^2χ^2$ with a small coupling constant $g$ ($g^2 \sim 10^{-7}$). We assume that there is a sequence of "trapping points" $ϕ_{0i}$ along the inflationary trajectory where particles of $χ$-field become massless and are rather effectively produced. We calculate the power spectrum of inflaton field fluctuations originated from a backreaction of $χ$-particles produced, using the Schwinger's "in-in" formalism. We show that the primary curvature power spectrum produced by these backreaction effects is blue, which leads to a strong overproduction of primordial black holes (PBHs) in subsequent radiation era.

Ecological Residual Risk Assessments: Past, Present, Future

Year: 2006

description: Section 112(f)(2) of the Clean Air Act, known as the Residual Risk Program, authorizes the EPA to implement risk-based standards for Hazardous Air Pollutants emissions, in order to protect human and ecological health. The EPA has created human and ecological risk assessment frameworks to help determine these risks. However, due to statutory ambiguities, budget constraints and ecosystem complexities, the EPA has encountered difficulties in determining adverse environmental effects. Using basic statutory interpretation and current literature, this study attempts to provide guidanceas to the legislative intent of the Residual Risk Program. Using this interpretation, the study also attempts to identify and provide solutions to existing gaps and weaknesses in the current ecological residual risk assessment process. These solutions will help generate a more robust and valid ecological residual risk assessment framework that can be used to determine adverse environmental effects, as defined for Section 112(f)(2) of the CAA.

Fugitive Dust Emissions: Accuracy of Gas Tracer Determinations
Creators: name: Frankel, Russell G.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1995

description: Few studies have addressed the accuracy of methods for measuring fugitive dust emission rates. We measured the accuracy of the gas tracer method under specific conditions, to determine if this method warrants further study. The gas tracer method is based on the assumption that the ratio of masses of emitted dust to emitted gas equals the downwind dust to gas concentration ratio. We modify this model by multiplying the ratio of downwind concentrations of dust and gas by a constant, k. A value of k=1 would mean that the gas tracer model works perfectly. Known masses of dust and sulfur hexafluoride were emitted. The emissions were timed to determine emission rates. Concentrations of dust and tracer were measured five meters downwind of the emission site. The experiment was performed sixteen times; in each case we determined a measured dust emission rate, a gas tracer prediction of the emission rate, and a value of k. The mean k-value was 1.03; the standard deviation was 0.14. Gas tracer predictions were within twenty-five percent of the actual dust emission rate in ninety-four percent of the test runs. The gas tracer method showed excellent accuracy under the tested conditions.

Oxidation of 2'-Deoxyguanosine and 8-Oxo-2'-deoxyguanosine by Dimethyldioxirane
Creators: name: Degen, Diana E.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2004

description: Oxidative damage to DNA can lead to cancer, aging, and neurological disorders. Of the four DNA bases, guanine is the most susceptible to oxidation. To help us further our knowledge of how oxidation contributes to illness and disease, it is important to study the oxidation process and products of 2'-deoxyguanosine (2'-dG). The oxidation product of 2'-dG, 8-oxo-2'-deoxyguanosine (8-oxo-2'-dG), is even more susceptible to oxidation than 2'-dG, and for this reason, it is imperative to study its oxidation products as well. For our study, oxidations of 2'-deoxyguanosine and 8-oxo-2' -deoxyguanosine were conducted with the powerful chemical oxidant dimethyldioxirane (DMDO). Oxidation products were then characterized with the use of HPLC, proton and multidimensional heteronuclear NMR, and electrospray MS in the positive ion mode. Because DMDO reacts selectively, it was expected that oxidation would occur at all types of double bonds, and possibly at NH2 or NH. However, it was found that the major product fraction was formed from epoxidation of the C-4 to C-5 double bond followed by solvolysis. Hence, in the reaction of DMDO with 2'-deoxyguanosine, epoxidation followed by hydrolysis or methanolysis formed 4,5-dihydro-4,5-dihydroxy-2'-deoxyguanosine and 4,5-dihydro-4-hydroxy-5-methoxy-2'-deoxyguanosine respectively. When DMDO reacted with 8-oxo-2'-deoxyguanosine in a solution of water and methanol, epoxidation followed by hydrolysis resulted in the formation of 4,5-dihydro-4,5-dihydroxy-8-oxo-2'-deoxyguanosine and epoxidation followed by methanolysis resulted in the formation of 4,5-dihydro-4-hydroxy-5-methoxy-8-oxo-2'-deoxyguanosine. The latter was further verified by conducting oxidations in perdeuterated methanol. This research concludes that DMDO, which has an oxidation mechanism analogous to the mixed-function oxidases, generates products distinct from those arising from radical chemistry.

description: The next galactic core-collapse supernova (CCSN) has already exploded, and its electromagnetic (EM) waves, neutrinos, and gravitational waves (GWs) may arrive at any moment. We present an extensive study on the potential sensitivity of prospective detection scenarios for GWs from CCSNe within 5Mpc, using realistic noise at the predicted sensitivity of the Advanced LIGO and Advanced Virgo detectors for 2015, 2017, and 2019. We quantify the detectability of GWs from CCSNe within the Milky Way and Large Magellanic Cloud, for which there will be an observed neutrino burst. We also consider extreme GW emission scenarios for more distant CCSNe with an associated EM signature. We find that a three detector network at design sensitivity will be able to detect neutrino-driven CCSN explosions out to ~5.5 kpc, while rapidly rotating core collapse will be detectable out to the Large Magellanic Cloud at 50kpc. Of the phenomenological models for extreme GW emission scenarios considered in this study, such as long-lived bar-mode instabilities and disk fragmentation instabilities, all models considered will be detectable out to M31 at 0.77 Mpc, while the most extreme models will be detectable out to M82 at 3.52 Mpc and beyond.

Transport of Powdered Activated Carbon Through Porous Media for In-Situ Remediation Applications
Creators: name: Mahmood, Ferdous
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1996

description: Laboratory column experiments were conducted to investigate the transport of powdered activated carbon through porous media. A constant flow of PAC slurry was pumped through a packed bed of sand column to simulate constant flow conditions that would be encountered if the PAC slurry were to be introduced in to the subsurface using injection wells. Sand was chosen as the media for the packed bed because introduction of a PAC slurry is likely to be limited to coarse-media aquifers. The PAC particles were heterogeneous and their diameters ranged from less than 1 μm to about 10 μm. The sand media was uniform with mean diameters 0.5 mm and 1.0 mm. Transport efficiencies of PAC particles at any given time were determined by measuring the ratio of effluent to influent particle concentrations at that time. The effects of media size, column length, PAC particle size, and PAC particle concentration on transport efficiencies were investigated by running the column experiments for about 200 hours. Transport efficiencies decreased rapidly with increasing PAC particle size; 5 μm PAC particles exhibiting less than 10% transport efficiency through either the 0.5 mm or the 1.0 mm sand media. Transport efficiencies increased with decreasing PAC particle concentration, but the reduction of PAC particle concentration by one order of magnitude showed only limited increase in transport efficiency. During the later stages of the experimental run, transport efficiencies decreased for the 0.5 mm sand media but no such trend was observed for the 1.0 mm sand media during the course of the experiment (200 hours). For the 0.5 mm media, although peak transport efficiencies occurred at later times for longer column lengths, the effects of column length were not very apparent in these experiments which were conducted at the centimeter-scale of length.

description: Pharmacogenomic (PGx) testing is increasingly entering mainstream clinical practice and is of great interest to patients and providers.1 Meanwhile, patient genetic literacy is generally low and is frequently cited as a barrier to PGx implementation. Disease risk research indicates that individuals with greater genomic literacy are more equipped to make informed decisions about whether to obtain genetic testing, understand results, and take appropriate action based on the findings.2,3 Several validated survey instruments have been developed to assess patient knowledge of key genetic concepts.4–7 However, none of these measures tests concepts related to PGx and to date no PGx-specific validated instruments have been developed. Here, we describe the first steps in this process: understanding patients’ experience with PGx via scoping literature review.

description: The aim of this review is to summarise how neural activity evoked by the Hariri task and its variants, is altered by (i) a number of sample characteristic and paradigm-design choices, and in (ii) participants with a mental health diagnosis or high levels of clinically relevant symptoms, both in terms of group averages and at the level of the individual participant. We hope that through a greater understanding of the influence of these study design parameters we will uncover a more comprehensive understanding of emotional face processing in health and ill-health, as well as increasing researcher’s awareness of the impact of seemingly small task-design choices.

An Analysis of Residence Time Distributions in Clearwells of North Carolina Water Treatment Facilities
Creators: name: Jackson, Jay
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1994

description: This paper focuses on the detention time, T, in the clearwells of thirteen water treatment plants in North Carolina, with a variety of different shapes, inlet and outlet, and internal baffling configurations. This paper evaluates the residence time distributions (RTDs) in the finished water storage tanks for the thirteen facilities. Tracer data used to evaluate the RTDs were taken from tracer studies performed by consulting engineers and treatment plant personnel and submitted to the Public Water Supply Section of the North Carolina Department of Environment, Health, and Natural Resources (NCDEHNR) in Raleigh, North Carolina. The purpose of this study was to evaluate the RTDs in a sample of clearwells at water treatment facilities in North Carolina in order to relate characteristics of the RTD to clearwell design. The following are the key steps that were performed to evaluate the RTDs and the objective of each step: The RTDs were generated from the test data, normalized, and plotted for each clearwell. By calculating the mean and variance of the RTD, a description of tank behavior was made using the Tanks-in-Series model. The RTD for each clearwell was plotted against the predicted Tanks-in-Series curve. The RTD was adjusted for dead space volume (where applicable) to provide a "best-fit" to the calculated Tanks-in-Series curve. Engineering sketches showing the clearwell inlet, outlet, and internal baffling configuration were developed. Factors that cause dead space volume and shortcircuiting in the clearwell were considered based on the RTDs and clearwell configuration. From the RTDs, T10 was determined for each clearwell, and a comparison of its value to the EPA Guidance Manual "Rule of Thumb" values was made. An attempt was made to classify the behavior of the clearwells based on similarities between their RTDs and their physical configurations. A comparison was made between the level of disinfection achieved in the clearwell based on actual tank behavior and the level that would be achieved if the tank was to behave with a T10 as estimated by the Guidance Manual "rule of thumb" fractions.

Testing of a Multicomponent Model of Adsorption and Biodegradation of Natural Organic Matter on Activated Carbon
Creators: name: Garber, James B.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1990

description: Adsorption and biodegradation studies were performed to characterize the components present in natural organic material (NOM) obtained from Lake Drummond, in southeastern Virginia. NOM adsorbability was characterized by dividing it into fictive components, using the Ideal Adsorbed Solution Theory (IAST) to find the Freundlich parameters and initial concentration of each. This was done for ozonated and ozonated-biostabilized NOM. The isotherm results, along with the results of the biokinetic experiment, were used to determine the components of the model NOM solution. A batch biokinetic study was performed to determine the biokinetic parameters for the ozonated NOM solution. A first-order model was fit to the experimental data, giving a first-order rate constant, yield coefficient, and coefficient of microbial decay for the biodegradable fraction of the NOM. A multicomponent model developed by Pedit (1988) was tested using the experimentally determined adsorption and biodegradation parameters. The model failed to predict the breakthrough of total organic carbon (TOC) and the resulting total inorganic carbon (TIC) production when the biodegradable fraction of NOM was assumed to be 55 percent, as determined using a continuous flow GAC reactor which had apparently reached an exhaustion of adsorption capacity. The model results were improved when the biodegradable fraction was assumed to be 15 percent, as obtained from the batch biokinetic experiment. This suggests that slow adsorption, in addition to biodegradation, may have been responsible for long term TOC removal in the continuous flow GAC reactor.
