Copper and Zinc Nanoparticles as Microbial Disinfectants in Water
Creators: name: Komandur, Abhinav Srinivasan Ramanujam

Year: 2013

description: Waterborne illness is one of the world's most pervasive causes of morbidity and mortality, with severe health, social, environmental and economic impacts. Human faeces are often inadequately managed and contaminate community and household water supplies. Sustainable safe community and household water access is often not achieved in the developing world and adverse health impacts can result from faecal contamination of water. Metals, particularly copper and zinc, have been proposed as effective disinfectants of drinking water. This research aimed to quantify the overall disinfecting effects of a 0.2 mg/L and 2mg/L dose of copper and zinc oxide nanoparticles, as well as the kinetics of such disinfection, on three test organisms; Bacillus cereus spores, Escherichia coli log-phase cells, and MS2 coliphage. Experiments were conducted in pH 7.3, 10 g/L (approximately 42mM)HEPES-buffered water with and without about 10 mg/L added natural organic matter (NOM). The concentrations of culturable microorganisms were assayed at 0, 20, 60, 180, and 360 minutes. Copper and zinc oxide nanoparticles were found to be effective for same-day or overnight achievement of the World Health Organisation (W.H.O.) "protective" level of disinfection (2 log[10] or 99% reduction) for E. coli in both experimental waters, and B. cereus spores in waters without added NOM. Measurable inactivation was not observed against MS2 coliphage for the low dose, although some inactivation (0.53 to 0.78 log[10] reduction in 6 hours in NOM-amended and NOM-negative waters, respectively) was achieved at the high dose. Some other experimental conditions yielded inactivation, but it was not rapid or extensive enough to achieve the W.H.O. protective performance target for same-day or overnight use. Overall, the combined use of copper and zinc nanoparticles shows promise for effective point-of-use disinfection of water low in turbidity and natural organic matter.

description: All content of this pre-registration and pre-analysis plan will be added to the existing paper "Citizens' Discrimination against Street-level Bureaucrats" to provide more clarity around core results from Study 1 & 2: “Using two discrete choice designs in a single nationally representative survey, we study ethnic discrimination in citizens’ choice of general practitioner (GP) in a Nordic welfare state. We find strong evidence of discrimination as GPs with Muslim names are chosen 15 percentage point less than majority named GPs with similar characteristics…additional analysis shows that discrimination is not reduced substantively if a performance measure for the GP is provided to citizens.” (Outtake from abstract). This follow-up intends to test if the above conclusion holds if (a) it is clear all GPs are educated at the best Danish medical schools and (b) alternative objective performance measures of the GPs quality. Both are intended to rule out statistical discrimination explanations for any remaining preference for a Danish named GP over a Muslim named GP.

Minimizing Disinfection By-Product Formation by Evaluating Drinking Water Treatment Options
Creators: name: Weiss, Michael
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2015

description: Disinfection byproducts (DBPs) are a category of chemicals that form via reaction of disinfectants with organic matter during drinking water treatment. Over 600 DBPs have been identified, yet only eleven are currently regulated in the United States for their potential human health risks. Unregulated DBPs have recently been shown to have genotoxic and cytotoxic effects in laboratory studies. Many water treatment plants (WTPs) have switched from traditional chlorination to chloramination to help meet the requirements of the Disinfection/Disinfection Byproducts Rules, possibly exposing consumers to elevated levels of unregulated DBPs. When a WTP considers alternate treatment processes, consulting engineer contractors run expensive pilot testing with little independent information to guide a WTP's decision. Data obtained from state WTPs, current literature, readily available source water parameters, treatment methodologies, and economics were utilized in the design of a decision tree which can assist WTPs in choosing optimal treatment methods to minimize DBP formation.

description: Characterizing the link between small-scale chromatin structure and large-scale chromosome folding during interphase is a prerequisite for understanding transcription. Yet, this link remains poorly investigated. Here, we introduce a simple biophysical model where interphase chromosomes are described in terms of the folding of chromatin sequences composed of alternating blocks of fibers with different thicknesses and flexibilities, and we use it to study the influence of sequence disorder on chromosome behaviors in space and time. By employing extensive computer simulations,we thus demonstrate that chromosomes undergo noticeable conformational changes only on length-scales smaller than $10^5$ basepairs and time-scales shorter than a few seconds, and we suggest there might exist effective upper bounds to the detection of chromosome reorganization in eukaryotes. We prove the relevance of our framework by modeling recent experimental FISH data on murine chromosomes.

Factors Related to the Adoption of Unit-Based Pricing for Solid Waste Management: A Case Study of Luzerne County, Pennsylvania
Creators: name: Eggers, Dolores M.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1993

description: This analysis compares communities in Luzeme County, Pennsylvania that are using variable rate pricing systems to finance solid waste management activities to those using other financing methods. Communities are compared on demographic and waste management system attributes. Driving factors behind the decision to adopt variable rates are also explored. Results of the analysis indicate that communities using variable rates exercise a higher level of control over solid waste collection, have higher median family incomes, are more urban, have higher populations of retired persons, and tend to have recycling programs. These communities are also more likely to be boroughs and to be relatively small geographically. Results also suggest the existence of a progression in financing methods from tax based to flat rate to variable rate. The study further shows that the retired population can have a significant impact on waste management financing decisions.

description: We simulate a two dimensional model of self-propelled particles confined by a deformable boundary. The particles tend to accumulate near the boundary and the shape of the boundary deforms upon the collisions. We find that there are two typical stages in the variation of the morphology with the increase of active force. One is at small force characterized by radially inhomogeneous redistribution of particles and suppression of local fluctuations of the boundary. The other is at large force featured by angularly redistribution of particles and global shape deformation of the boundary. The last two processes are strongly cooperative. We also find different mechanisms in the particle redistribution and opposite force-dependences of the rate of the shape variation at low and high particle concentrations.

description: We examine the results of Chiral Effective Field Theory ($χ$EFT) for the scalar- and spin-dipole polarisabilities of the proton and neutron, both for the physical pion mass and as a function of $m_π$. This provides chiral extrapolations for lattice-QCD polarisability computations. We include both the leading and sub-leading effects of the nucleon's pion cloud, as well as the leading ones of the $Δ(1232)$ resonance and its pion cloud. The analytic results are complete at N$^2$LO in the $δ$-counting for pion masses close to the physical value, and at leading order for pion masses similar to the Delta-nucleon mass splitting. In order to quantify the truncation error of our predictions and fits as $68$\% degree-of-belief intervals, we use a Bayesian procedure recently adapted to EFT expansions. At the physical point, our predictions for the spin polarisabilities are, within respective errors, in good agreement with alternative extractions using experiments and dispersion-relation theory. At larger pion masses we find that the chiral expansion of all polarisabilities becomes intrinsically unreliable as $m_π$ approaches about $300\;$MeV---as has already been seen in other observables. $χ$EFT also predicts a substantial isospin splitting above the physical point for both the electric and magnetic scalar polarisabilities; and we speculate on the impact this has on the stability of nucleons. Our results agree very well with emerging lattice computations in the realm where $χ$EFT converges. Curiously, for the central values of some of our predictions, this agreement persists to much higher pion masses. We speculate on whether this might be more than a fortuitous coincidence.

Sewer System Planning Using Household Willingness to Pay Data
Creators: name: Swarna, Venkateswarlu
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1993

description: The planning problem of this research deals with using household willingness to pay information to improve sewer system planning in less developed countries, particularly in selecting the regions to be served by sewers and in transporting the wastewater from these regions to a treatment plant through an optimal network of trunk sewers. To address the planning problem, this report has developed three planning models of varying mathematical complexity and has demonstrated their application for a hypothetical city. The first model, the least complex of the three, approaches the planning problem by assuming that trunk sewer costs can be ignored, and it solves the model with simple arithmetic calculations. This model is best for cities in which trunk sewer costs are negligible or are covered by subsidies. The second model considers trunk sewer costs and assumes trunk sewer routing. It uses linear programming to determine the optimal solution even though the model involves binary variables. This model is applicable where trunk sewer routing choices can be made based on engineering judgment. The final model, the most complex of the three, considers trunk sewer costs and it determines optimal trunk sewer routing. This model uses mixed integer programming for solution; it is most appropriate for regions in a city that are flat and distant from treatment plants, conditions which essentially do not present an obvious engineering basis for deciding trunk sewer routing.

description: We propose a set of boundary terms for higher spin theories in AdS$_3$ that lead to a well-defined variational principle compatible with Dirichlet boundary conditions for the metric and higher spin fields. These boundary terms are valid for higher spin theories in the Fefferman-Graham gauge and they allow us to compute the canonical free energy of higher spin black holes directly from the Euclidean, covariant, on-shell action. Using these results we reproduce the thermodynamics of the higher spin black hole of Ammon, Gutperle, Kraus, and Perlmutter and comment on the corresponding theory of induced $\cal{W}$-gravity at the boundary.

description: We present experimental results on dense corn-starch suspensions as examples of non-Brownian, nearly-hard particles that undergo continuous and discontinuous shear thickening (CST and DST) at intermediate and high densities respectively. Our results offer strong support for recent theories involving a stress-dependent effective contact friction among particles. We show however that in the DST regime, where theory might lead one to expect steady-state shear bands oriented layerwise along the vorticity axis, the real flow is unsteady. To explain this, we argue that steady-state banding is generically ruled out by the requirement that, for hard non-Brownian particles, the solvent pressure and the normal-normal component of the particle stress must balance separately across the interface between bands. (Otherwise there is an unbalanced migration flux.) However, long-lived transient shear-bands remain possible.
An exploration of the emotion management of faculty staff at a Swiss private Higher Education Institute

Subjects: Emotion Management

description: The principal aim of this study was to obtain an understanding of the relative importance of emotion management for the Swiss private higher education sector, and for the lecturing profession in general. Extant literature has focused on the emotion management of teachers and lecturers working in the public sector but has somewhat overlooked the private higher education sector. A single case study design was selected for this research, which consisted of a well-established and highly regarded Swiss private higher education institute. Focus groups were conducted with three groups of faculty staff at the case institute. This was followed up by eleven individual interviews. Thematic analysis was then used to analyse the data, resulting in the identification of several core themes. The findings show that emotion management is an essential element of the lecturing profession within the Swiss private higher education sector. There was evidence of emotional labour in action, with participants enacting the various emotion regulation strategies as espoused throughout the literature. This study identified that ‘naturally felt emotions’ and ‘deep acting’ were the preferred emotion regulation strategies. The prescriptive and philanthropic categories of the typology of workplace emotion were found to be the primary motivators behind the faculty performance. This thesis has made strides in expanding the field by providing new insights into the relevance of emotion management for professional occupations, specifically those of faculty staff. Overall, participants reported more positive than negative outcomes associated with emotion management, suggesting less of a dichotomy of outcomes in comparison to previous studies. The findings show that a number of contextual factors also have an influence on the emotion management of individual lecturers. Backstage areas and humour were found to be the most common coping strategies which participants used to detach from the job. Unexpectedly, cultural diversity was considered as having implications for the emotion management of lecturers. The research findings represent a further step towards developing an understanding of emotions and their management in a private higher education setting.

Year: 1991

description: In the fluorescence-washing technique, oleic acid particles tagged with uranine are washed out and analyzed fluorometrically. The possible sources of errors in the technique are evaluated in this study. First, the sensitivity of uranine fluorescence in different solutions is compared. The results indicate that uranine in distilled water with pH 10 buffer and in sodium hydroxide have high readings. Second, the interference of oleic acid in uranine solutions is investigated. The results indicate that there is no interference of oleic acid in distilled water and sodium hydroxide under our operating conditions. However, there is a significant quenching effect of oleic acid in ethanol. Third, the extraction ability of different solutions from glass fiber and Teflon filters is tested. The results indicate that distilled water and sodium hydroxide have high extraction ability. Fourth, based on the results above, distilled water is the best washing solution for inlet washing. Fifth, two commercial samplers, the Portable Indoor Particulate Samplers (PIPS) and Saturation monitors, have been calibrated in the test chamber. Sixth, some potential errors generated using this fluorescence-washing technique in practice are discussed. Seventh, a set of optimal operating conditions and a standard operating protocol are proposed.

description: Long-distance quantum communication relies on the ability to efficiently generate and prepare single photons at telecom wavelengths. In many applications these photons must also be indistinguishable such that they exhibit interference on a beamsplitter, which implements effective photon-photon interactions. However, deterministic generation of indistinguishable single photons with high brightness remains a challenging problem. We demonstrate two-photon interference at telecom wavelengths using an InAs/InP quantum dot in a nanophotonic cavity. The cavity enhances the quantum dot emission, resulting in a nearly Gaussian transverse mode profile with high out-coupling efficiency exceeding 36% after multi-photon correction. We also observe Purcell enhanced spontaneous emission rate up to 4. Using this source, we generate linearly polarized, high purity single photons at 1.3 micron wavelength and demonstrate the indistinguishable nature of the emission using a two-photon interference measurement, which exhibits indistinguishable visibilities of 18% without post-selection and 67% with post-selection. Our results provide a promising approach to generate bright, deterministic single photons at telecom wavelength for applications in quantum networking and quantum communication.

Year: 2013

description: Using the MARKAL linear programming energy systems optimization model and US EPA Nine-Region database, the future climate change influence on US heating and cooling energy demands for the SRES A2 scenario is quantified. Changes in energy demands are estimated using population-weighted HDD and CDD. Cooling demands in 2050 for the residential and commercial sectors increase by 32.53 and 33.53% respectively, while heating demands decrease by 12.93 and 14.14%, causing national energy demands to increase by 375 PJ(0.33%). Climate change increases the 2050 residential and commercial cooling the most where CDD increase most (Pacific, East North Central and West North Central regions), and decrease space heating the most where HDD decrease most (South Atlantic, West South Central and East South Central regions). Climate change causes 2050 national residential and commercial direct and indirect emissions to increase for CO2, NOx and SO2, while residential PM10 emissions decrease and commercial PM10 increase.

Chamber Validation of a Localized Open-path FTIR Spectrometer
Creators: name: Dodson, Ashley
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1999

description: A portable open-path FTIR instrument has been developed, that incorporates a Midac FTIR spectrometer, a modified White cell, and a battery pack. The design includes a removable cover for the White cell, which allows for ease in path length determination, calibration, and background collection, which are challenging using conventional open-path FTIR spectrometers. In the new instrument, a folded open-path of up to 120 meters is created using mirrors and two retroreflectors. Due to the long path lengths which can be achieved, chemicals can be detected at the part per billion level. In addition, the IR beam is contained within a 60 L cell. Therefore, when concentrations of a chemical are detected in a room, the location of the concentration can be pinpointed. The instrument has been evaluated in an exposure chamber using a range of known concentrations. The chemicals used were nitrous oxide, trichloroethylene, and methyl ethyl ketone. The limit of detection was calculated for each chemical, and found to be in the low part per billion level for nitrous oxide and trichloroethylene. For methyl ethyl ketone, the limit of detection was found to be approximately 0.1 parts per million. For nitrous oxide, performance parameters, including precision, accuracy, and bias were evaluated according to NIOSH guidelines, and the instrument performed well within the NIOSH recommendations, having bias better than +/-10% and accuracy better than +/-25%.

Progenitor-dependent Explosion Dynamics in Self-consistent, Axisymmetric Simulations of Neutrino-driven Core-collapse Supernovae

description: We present self-consistent, axisymmetric core-collapse supernova simulations performed with the Prometheus-Vertex code for 18 pre-supernova models in the range of 11-28 solar masses, including progenitors recently investigated by other groups. All models develop explosions, but depending on the progenitor structure, they can be divided into two classes. With a steep density decline at the Si/Si-O interface, the arrival of this interface at the shock front leads to a sudden drop of the mass-accretion rate, triggering a rapid approach to explosion. With a more gradually decreasing accretion rate, it takes longer for the neutrino heating to overcome the accretion ram pressure and explosions set in later. Early explosions are facilitated by high mass-accretion rates after bounce and correspondingly high neutrino luminosities combined with a pronounced drop of the accretion rate and ram pressure at the Si/Si-O interface. Because of rapidly shrinking neutron star radii and receding shock fronts after the passage through their maxima, our models exhibit short advection time scales, which favor the efficient growth of the standing accretion-shock instability. The latter plays a supportive role at least for the initiation of the re-expansion of the stalled shock before runaway. Taking into account the effects of turbulent pressure in the gain layer, we derive a generalized condition for the critical neutrino luminosity that captures the explosion behavior of all models very well. We validate the robustness of our findings by testing the influence of stochasticity, numerical resolution, and approximations in some aspects of the microphysics.

Use of the C18 (Octadecyl) Solid Phase Extraction Column for Wastewater Toxicity Identification and Characterization
Creators: name: Champlin, Tory L.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1989

description: Biomonitoring requirements are continually being added to NPDES permits. As a result, many municipal wastewater treatment facilities have been identified as having effluent acute toxicity. To solve this problem, the Environmental Protection Agency (EPA) has developed a Toxicity Identification Evaluation (TIE) protocol. This protocol lists a set of simple procedures which are used to separate whole effluent samples into different fractions containing different classes of similar compounds. Toxic fractions are further separated and concentrated using various techniques to assist in the possible identification of certain classes of suspected toxic compounds. Once sample fractionation and toxicity testing have been thoroughly investigated, chemical-specific analyses are conducted to tentatively identify toxic constituents. The C18 (Octadecyl) Solid Phase Extraction (SPE) Column is used in the TIE protocol to separate and concentrate moderately polar to nonpolar organic compounds from toxic effluent samples. An increasing gradient of methanol (MeOH) in water is used to elute the column; the objective is to separate retained compounds into eight different fractions based on their polarity. The objective of conducting this research is to determine if the C18 SPE Column elution procedure is a viable technique for the identification and characterization of toxic effluents. This study showed that the C18 column was able to remove compounds causing acute toxicity from samples collected at the Cross Creek Wastewater Treatment Plant (WWTP) in Fayetteville, NC. The 80 to 85 percent MeOH/H20 fractions contained the most toxicity. However, laboratory tests of the procedure using known target compounds indicated that several different MeOH/H20 fractions contained each individual compound thus showing deficiencies in resolution. Moreover, the target compounds that were selected differed widely in polarity (as indicated by the compounds octanol/water partitioning coefficient), yet this did not cause a wide separation of these compounds into specific MeOH/H2O fractions. This research showed the C18 SPE column is capable of retaining relatively non-polar compounds as indicated by the target compound evaluation. These compounds were effectively eluted from the CIS SPE column with MeOH/H20, but separation was not well defined. In the situation of toxic wastewaters, where numerous nonpolar organic compounds may possibly be present in WWTP's discharge, the C18 SPE column provides little information regarding the identity of the non-polar organics causing toxicity in a toxic MeOH/H20 fraction.
Associative Yang-Baxter equation for quantum (semi-)dynamical R-matrices

description: In this paper we propose versions of the associative Yang-Baxter equation and higher order $R$-matrix identities which can be applied to quantum dynamical $R$-matrices. As is known quantum non-dynamical $R$-matrices of Baxter-Belavin type satisfy this equation. Together with unitarity condition and skew-symmetry it provides the quantum Yang-Baxter equation and a set of identities useful for different applications in integrable systems. The dynamical $R$-matrices satisfy the Gervais-Neveu-Felder (or dynamical Yang-Baxter) equation. Relation between the dynamical and non-dynamical cases is described by the IRF-Vertex transformation. An alternative approach to quantum (semi-)dynamical $R$-matrices and related quantum algebras was suggested by Arutyunov, Chekhov and Frolov (ACF) in their study of the quantum Ruijsenaars-Schneider model. The purpose of this paper is twofold. First, we prove that the ACF elliptic $R$-matrix satisfies the associative Yang-Baxter equation with shifted spectral parameters. Second, we directly prove a simple relation of the IRF-Vertex type between the Baxter-Belavin and the ACF elliptic $R$-matrices predicted previously by Avan and Rollet. It provides the higher order $R$-matrix identities and an explanation of the obtained equations through those for non-dynamical $R$-matrices. As a by-product we also get an interpretation of the intertwining transformation as matrix extension of scalar theta function likewise $R$-matrix is interpreted as matrix extension of the Kronecker function. Relations to the Gervais-Neveu-Felder equation and identities for the Felder's elliptic $R$-matrix are also discussed.
