Feasibility Analysis of Underground Rainwater Cistern Retrofit for Irrigation Purposes for Baity Hill Mason Farm Student Housing Complex
Creators: name: Cofield, Charles

Year: 2018

description: As part of the University of North Carolina at Chapel Hill (UNC-CH) Three Zero Environmental Initiative, the University proposes to convert an existing underground detention facility at Baity Hill at Mason Farm Student Housing Complex into a rainwater cistern. The property is currently irrigated using metered potable water from the water main running parallel with Mason Farm Road. The University would like to use the detention facility as the primary water source for irrigation. A hydrologic analysis has been conducted to determine how much runoff is reaching the existing underground detention facility.  Using ten years’ worth of irrigation demand data provided by UNC-CH and North Carolina State University Biological & Agricultural Engineering’s (NCSU-BAE) Rainwater Harvester tool, 75% (+/- 7%) of the annual irrigation demand could be met by the rainwater cistern. Two options for a secondary source for irrigation were considered: the existing potable water line and an abandoned non-potable reclaimed water line that would need to be extended to the property. The net present value cost to irrigate the property over 15 years could decrease roughly 40% compared to current operations.This report discusses the feasibility of converting the underground detention facility into a rainwater cistern and available options for secondary sources. Detailed descriptions of the project site, the overarching objectives of the Three Zeros Initiative behind this proposal. pertinent calculations, details, and cost-benefit analyses can be found in the sections, tables, and appendices to follow.

Evaluation of School Worker Exposure to Methanol from Spirit Duplicator Use
Creators: name: Susie, Pam
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1991

description: Methanol breathing zone exposures to schoolworkers using spirit duplicators were measured using a Miran IR gas analyzer. Sufficient data was collected to describe the distribution of exposures to teachers and teaching assistants. A questionnaire focusing on duplicator use patterns was distributed throughout sampled schools. The mean exposure to teachers from duplicator operation is 404 ppm with a standard deviation of 296 ppm. The mean exposure to teaching assistants is 355 ppm with a standard deviation of 423. Time weighted average exposures of two clerical workers who duplicate materials for multiple classes exceeded 780 ppm. The mean maximum daily exposure duration reported in questionnaires was: 53 minutes for clerical workers, 33 minutes for teaching assistants and 18 minutes for teachers. Collating and handling freshly duplicated materials contributes significantly to total methanol body burden. The probability that teachers and teaching assistants are receiving exposures in excess of the OSHA 15 minute STEL of 250 ppm is over 13% after 5 minutes of duplicator use. This probability increases to 61% for teachers and 46% for teaching assistants after 15 minutes of use.

description: The performance of an energy system under a real-time pricing mechanism depends on the consumption behavior of its customers, which involves uncertainties. In this paper, we consider a system operator that charges its customers with a real-time price that depends on the total realized consumption. Customers have unknown and heterogeneous consumption preferences. We propose behavior models in which customers act selfishly, altruistically or as welfare-maximizers. In addition, we consider information models where customers keep their consumption levels private, communicate with a neighboring set of customers, or receive broadcasted demand from the operator. Our analysis focuses on the dispersion of the system performance under different consumption models. To this end, for each pair of behavior and information model we define and characterize optimal rational behavior, and provide a local algorithm that can be implemented by the consumption scheduler devices. Analytical comparisons of the two extreme information models, namely, private and complete information models, show that communication model reduces demand uncertainty while having negligible effect on aggregate consumer utility and welfare. In addition, we show the impact of real-time price policy parameters have on the expected welfare loss due to selfish behavior affording critical policy insights.

The Synthesis of Deuterated Bromodichloromethane, Deuterated Chlorodibromomethane and Mixed Halogenated Acetic Acids

Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1993

description: The purpose of this research project was to develop procedures for the preparation of isotopically-labeled, mixed halogenated disinfection by-products. Deuterated bromodichloromethane (deuterated BDCM), was synthesized using an aluminum catalyzed reaction. Equal volumes of deuterated chloroform (25 mL) and bromoethane (25 mL) were mixed in a 100 mL round bottom flask. Enough AlCl3 was added to the flask such that the reaction mixture turned dark red in color. The reaction was allowed to stir for 46 hours. The product was purified through fractional distillation, in which three fractions were collected. Through GC-MS analysis, the purity of fraction 2 (65-72°C) was calculated to be 93% and that of fraction 3 (73-78°C) was 85%. For both fractions, BDCM was 99% deuterium enriched. [13]C NMR and GC-MS analyses indicated that the impurity in both of fractions 2 and 3 was deuterated chlorodibromomethane. This indicated that AlCl3 was reacting with the generated deuterated BDCM to yield deuterated chlorodibromomethane. Therefore, by letting this same reaction stir for 7 days it was possible to obtain a significant amount (approximately 5 g) of deuterated chlorodibromomethane. Bromochloro-, chlorodibromo-, and bromodichloroacetic acid were all obtained through a literature synthesis (Zimmer et al., 1990). A new experimental procedure was developed for the synthesis of bromodichloroacetic acid (CBrCl2C00H). Allowing bromodichloromethane to react with 1.6 M n-butyllithium in hexanes, yielded the bromodichloromethide anion. The anion was carboxylated by the addition of dry ice to yield CBrCl2C02-Li+. The lithium salt was added to water and acidified with concentrated hydrochloric acid. CBrCl2COOH was extracted from solution with methylene chloride. Having demonstrated the feasibility of this reaction, attempts were made to develop a procedure based on Ba^14^CO3 as a source of CO2. Pilot studies involving BaC03/H2S04 as the CO2 source proved unsuccessful. While using unrealistic quantities of BaCO3, (5 g), only trace quantities of bromodichloroacetic acid were obtained.

description: In the field of optomechanics, radiation forces have provided a particularly high level of control over the frequency and dissipation of mechanical elements. Here we propose a class of optomechanical systems in which light exerts a similarly profound influence over two other fundamental parameters: geometry and mass. By applying an optical trap to one lattice site of an extended phononic crystal, we show it is possible to create a tunable, localized mechanical mode. Owing to light's simultaneous and constructive coupling with the structure's continuum of modes, we estimate that a trap power at the level of a single intracavity photon should be capable of producing a significant effect within a realistic, chip-scale device.

Instantaneous non-local computation of low T-depth quantum circuits
Creators: name: Speelman, Florian
Publisher: name: arXiv
Year: 2015
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: Instantaneous non-local quantum computation requires multiple parties to jointly perform a quantum operation, using pre-shared entanglement and a single round of simultaneous communication. We study this task for its close connection to position-based quantum cryptography, but it also has natural applications in the context of foundations of quantum physics and in distributed computing. The best known general construction for instantaneous non-local quantum computation requires a pre-shared state which is exponentially large in the number of qubits involved in the operation, while efficient constructions are known for very specific cases only. We partially close this gap by presenting new schemes for efficient instantaneous non-local computation of several classes of quantum circuits, using the Clifford+T gate set. Our main result is a protocol which uses entanglement exponential in the T-depth of a quantum circuit, able to perform non-local computation of quantum circuits with a (poly-)logarithmic number of layers of T gates with quasi-polynomial entanglement. Our proofs combine ideas from blind and delegated quantum computation with the garden-hose model, a combinatorial model of communication complexity which was recently introduced as a tool for studying certain schemes for quantum position verification. As an application of our results, we also present an efficient attack on a recently-proposed scheme for position verification by Chakraborty and Leverrier.
Application of Flow Injection Analysis to Assess the Impact of Chlorination on Total Cyanide Concentration in Municipal Wastewaters
Creators: name: Cook, Steven J.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1999

description: Cyanide is well known as a toxin to humans and aquatic life. Consequently, limits on the discharge of cyanide have been imposed to protect the environment. Concentrations as low as 5 ppb have been reported to be detrimental to sensitive aquatic life; thus, the strictest limits for cyanide discharge are placed on waste water treatment plants. Measurements for cyanide in waste water are not very consistent at this concentration, so any type of interference or contamination will influence a facility's ability to demonstrate compliance with its discharge permit. This study formed part of a project conceived by a consortium of North Carolina waste water utilities that continued to violate discharge permits for a variety of species. The study was designed to determine sources of any interference or contamination that could lead to a bias in cyanide measurements using existing methodology. An earlier component of the larger study indicated that those plants using chlorination were most likely to have recurrent problems meeting their discharge permit levels for cyanide. In addition, the analytical method for total cyanide as practiced at the utility or contract laboratories was found to suffer many shortcomings. Published literature states that both nitrite and sulfide are known to interfere with the total cyanide analysis. This research, therefore, aimed to study the potential artifactual presence of cyanide utilizing an alternative methodology. The data collected from the various experiments were intended to validate if the cyanide formation was truly occurring in the chlorination process or if the cyanide were an artifact of the testing methodology. This was designed to be done through sampling before, during and after the chlorination process. These waste water samples were then treated to identify where the cyanide formation reaction was occurring and the chemical species involved. Determination of the levels of these chemical constituent was also performed to observe any correlation exists between these species and effluent cyanide concentrations. These collected waste water samples were treated in a variety of ways to account for possible chemical interfereces that may contribute to high cyanide concentrations. Approaches were then developed to control these reactions and to assure stabilization of collected samples during analysis. This study attempts to furnish an approach for waste water utilities to ensure accurate monitoring of total cyanide in their effluent, and there by identify the source of true cyanide contamination when permit violations occur.

description: Grand-canonical fluctuations of Bose-Einstein condensates of light are accessible to state-of-the-art experiments [J. Schmitt et al., Phys. Rev. Lett. 112, 030401 (2014).]. We phenomenologically describe these fluctuations by using the grand-canonical ensemble for a weakly interacting Bose gas at thermal equilibrium. For a two-dimensional harmonic trap, we use two models for which the canonical partition functions of the weakly interacting Bose gas are given by exact recurrence relations. We find that the grand-canonical condensate fluctuations for weakly interacting Bose gases vanish at zero temperature, thus behaving qualitatively similar to an ideal gas in the canonical ensemble (or micro-canonical ensemble) rather than the grand-canonical ensemble. For low but finite temperatures, the fluctuations remain considerably higher than for the canonical ensemble, as predicted by the ideal gas in the grand-canonical ensemble, thus clearly showing that we are not in a regime in which the ensembles are equivalent.

Identification and Quantitation of DNA Adducts from Calf Thymus DNA Exposed to 1,2-Epoxybutene
Creators: name: Lin, Yu-Pang
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1994

description: This study was conducted to characterize the DNA adducts formed when adenine, guanosine or calf thymus DNA is reacted with 1,2-epoxybutene (EB). HPLC separation coupled with diode-array detection was employed to isolate the adducts that were formed. Two EB-adenine products were identified as N^6-(2-hydroxy-3-buten-1-yI) adenine (EB-Ade I) and N^6-(1-hydroxy-3-buten-2-yI) adenine (EB-Ade II) by 1^H-NMR analysis. Two guanine adducts similar to those previously characterized as 7-(2-hydroxy-3-buten-l-yl) guanine (EB-Gua I) and 7-(l-hydroxy-3-buten-2-yl) guanine (EB-Gua II) were also collected. All four adducts were used as reference compounds to detect and quantitate the corresponding adduct species formed in DNA incubated in vitro with EB. EB-adenine and EB-guanine adducts were detected in EB-treated calf thymus DNA. The formation of EB-adenine adducts (1.0 x 10^-3 and 2.7 x 10^-3 EB-Ade I and II per adenine, respectively) in calf thymus DNA was approximately one tenth that of EB-guanine adducts (4.2 x 10^-2 and 3.0 x 10^-2 EB-Gua I and II per guanine, respectively). Since 1,3-butadiene (BD) and its metabolites, EB and diepoxybutane, induce nearly equal numbers of point mutations at A:T and G:C base pairs, the N^6-substituted adenine adducts may represent important promutagenic DNA adducts involved in BD-induced mutagenesis and carcinogenesis.

description: Coherent optical control of individual particles has been demonstrated both for atoms and semiconductor quantum dots. Here we demonstrate the emergence of quantum coherent effects in semiconductor Rydberg excitons in bulk Cu$_2$O. Due to the spectral proximity between two adjacent Rydberg exciton states, a single-frequency laser may pump both resonances with little dissipation from the detuning. As a consequence, additional resonances appear in the absorption spectrum that correspond to dressed states consisting of two Rydberg exciton levels coupled to the excitonic vacuum, forming a V-type three-level system, but driven only by one laser light source. We show that the level of pure dephasing in this system is extremely low. These observations are a crucial step towards coherently controlled quantum technologies in a bulk semiconductor.

description: We propose a novel pilot sequence design to mitigate pilot contamination in multi-cell multiuser massive multiple-input multiple-output networks. Our proposed design generates pilot sequences in the multi-cell network and devises power allocation at base stations (BSs) for downlink transmission. The pilot sequences together with the power allocation ensure that the user capacity of the network is achieved and the pre-defined signal-to-interference-plus-noise ratio (SINR) requirements of all users are met. To realize our design, we first derive new closed-form expressions for the user capacity and the user capacity region. Built upon these expressions, we then develop a new algorithm to obtain the required pilot sequences and power allocation. We further determine the minimum number of antennas required at BSs to achieve certain SINR requirements of all users. Numerical results are presented to corroborate our analysis and to examine the impact of key parameters, such as the pilot sequence length and the total number of users, on the network performance. A pivotal conclusion is reached that our design achieves a larger user capacity region than the existing designs and needs less antennas at the BS to fulfill the pre-defined SINR requirements of all users in the network than the existing designs.

description: The first order autoregressive (ARl) model proposed by Rappaport and Spear (1988) to determine physiological damping for solvent exposures over short time intervals was evaluated under field conditions. Two sets of data were collected for ethyl acetate, methylene chloride and perchloroethylene, respectively. Evaluation of the correlograms for each data set indicates that an AR(1) process may not be appropriate. The observed transmittance factors (inverse of damping) ranged from 0.47 to 0.64. The significance or causality of this observation is not presently known.

A Decision Framework for Evaluating Management Options for Potentially Hazardous Municipal Solid Waste
Creators: name: Draper, Kenyon L.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1996

description: Due to scarcity of pertinent data, much uncertainty is involved in determining how to best manage potentially hazardous products in the municipal wastestream. Thus, the objective has been to develop and demonstrate a formalized mechanism which communities can use to determine what types of information are most important and to explicitly include the best available information into a rational decision process. This decision framework evaluates alternatives with regard to both health risks and economics. Groundwater and air dispersion models are used to determine probability curves for the chemical and byproduct exposure ranges in groundwater, air, and food and the resulting health effects. The framework involves two phases: 1) determination of whether use of the present waste management system entails unacceptable health risks, and 2) determination of which alternative reduces the risk to acceptable levels at the lowest financial cost. To demonstrate the framework, a case study is conducted for plastics containing brominated fire retardants in the municipal wastestream of Charlotte, NC. Brominated dioxins and furans produced from the incineration of these plastics do not appear to involve unacceptable health risks for Charlotte and risk-reduction changes are unnecessary.
Differences in Baseline Levels of Airway Inflammation and Effect of Body Mass Index on Inflammation in Healthy, Atopic and Asthmatic Individuals
Creators: name: Patel, Rhea
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2011

description: Inflammationis a characteristic feature of airway diseases such as atopy and asthma. The presence of neutrophils, macrophages and eosinophils at baseline in the airways indicates activation of the innate immune system. Obesity, classified by Body Mass Index (BMI), is believed to be linked with a state of chronic inflammation. The Center for Environmental Medicine, Asthma and Lung Biology (CEMALB)has a database (General Screen(GS)database) which has analyzed several hundred human volunteers' sputum samples for cellular markers of inflammation. These markers or variables, all measured during the baseline state, include total and differential inflammatory cell count. This study performed a one-way Analysis of Variance (ANOVA) and a multivariate linear regression analysis on the GS database variables to investigate the relative differences in baseline levels of inflammation among healthy, atopic and asthmatic individuals, and to assess the effect of BMI on inflammation as moderated by disease status, respectively. Asthmatic individuals, on average, had significantly fewer numbers of airway macrophages than healthy individuals and a greater percentage of eosinophils than atopic and healthy individuals (p<0.05). There was a significant positive interaction between BMI and asthmatic individuals for the percentage of neutrophils (p=0.0122) and a corresponding negative interaction for the percentage of macrophages (p=0.0195). There were no significant interactions between BMI and atopic individuals. Overall, baseline levels of inflammation were significantly different among healthy, atopic and asthmatic individuals. BMI appeared to have an effect on constitutive inflammation in individuals with asthma, but not atopy without asthma.

description: We present accurate ab initio and quantum scattering calculations on a prototypical hybrid ion-atom system Yb$^+$-Rb, recently suggested as a promising candidate for the experimental study of open quantum systems, quantum information processing, and quantum simulation. We identify the second-oder spin-orbit (SO) interaction as the dominant source of hyperfine relaxation and decoherence in cold Yb$^+$-Rb collisions. Our results are in good agreement with recent experimental observations [L. Ratschbacher et al., Phys. Rev. Lett. 110, 160402 (2013)] of hyperfine relaxation rates of trapped Yb$^+$ immersed in an ultracold Rb gas. The calculated rates are 4 times smaller than predicted by the Langevin capture theory and display a weak $T^{-0.3}$ temperature dependence, indicating significant deviations from statistical behavior. Our analysis underscores the deleterious nature of the SO interaction and implies that light ion-atom combinations such as Yb$^+$-Li should be used to minimize hyperfine relaxation and decoherence of trapped ions in ultracold atomic gases.

A Mass Spectrometry/Mass Spectrometry Method for the Analysis of Polychlorinated Dibenzo-p-Dioxins and Dibenzofurans
Creators: name: Green, William Callison
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1993

description: Mass spectrometry/mass spectrometry (MS/MS) has been shown to be useful in the analysis of environmental samples for low (ppt) levels of compounds like polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs) in cases where interfering materials present in the samples made analysis by high resolution mass spectrometry (HRMS) difficult or impossible. While the technique shows promise because of its high selectivity, researchers have reported stability problems with mass spectrometry/mass spectrometry instruments and other questions regarding the reproducibility of analytical results exist. This study was undertaken to develop an MS/MS method for the analysis of PCDD/Fs, determine the stability of an MS/MS instrument over a period of months and to compare analytical results obtained by MS/MS with those obtained by HRMS. The results demonstrated that by following the protocol developed in the study, an MS/MS instrument can generate reproducible analytical results over a period of months and that quantitative results obtained by MS/MS were not significantly different from those obtained by HRMS.
The Effects of Coagulation, Ozonation, and Biodegradation on the Activated Carbon Adsorption of Aquatic Humic Substances
Creators: name: Harrington, Gregory W.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1987

description: The United States Environmental Protection Agency is currently in the process of adding or lowering the maximum contaminant levels of many organic compounds, including trihalomethanes (THMs). As a result, many water treatment facilities are expected to consider the use of processes such as ozone oxidation and granular activated carbon (GAC) adsorption. Since these processes are quite expensive, accurate design of these systems for the removal of humic substances, the precursors of THMs, is essential. This work examined the effects of bench scale coagulation, ozonation, and biodegradation processes on the adsorption of aquatic humic substances obtained from a swamp lake in southeastern Virginia. The equilibrium adsorption behavior was described by dividing each humic mixture into several fictive components and ideal adsorbed solution theory (IAST) was then used to find the Freundlich parameters and initial concentration of each component. IAST was found to provide adequate descriptions of humic substance adsorption, even though many assumptions in the model were not considered to be valid for humic solutions. This multicomponent adsorption model was used to show that compositional changes were responsible for increased adsorbability upon coagulation and for decreased adsorbability upon ozonation and biostabilization. Unfortunately, systematic changes in the IAST parameters were not found to occur with increasing ozone dose, thereby implying that accurate prediction and design of combined ozone and GAC systems may be difficult. However, a normalized adsorption isotherm showed some promise in this regard although the technique may not be applicable to kinetic systems. External mass transfer characteristics of humic solutions were examined with a mini-column adsorber. The free liquid diffusion coefficient was found to increase upon coagulation while no significant changes were observed after ozonation and biostabilization. Internal mass transfer characteristics were examined with a pore and surface diffusion model. The overall mass transfer rate was found to increase after coagulation and after ozonation and biostabilization. However, tests with three different ozone doses showed no change in mass transfer rates with ozone dose. In addition, the techniques used in this work were not found to be capable of describing the mechanism of humic substance diffusion.

description: The U.S. dairy industry faces a changing government policy environment in the year 2000. Milk producers are struggling, and will continue to struggle, to adjust to markets that are more dependent on the forces of supply and demand. Data from the 1993-95 Farm Costs and Returns Surveys and the 1996 Agricultural Resource Management Study show that dairy farm businesses in general did a fairly good job of meeting short-term debt, generating returns, and meeting long-term debt from 1993 to 1996. The analysis indicates that farm management strategies will play an important role in determining the overall profitability of a dairy farm business as Government supports decline. However, the 1996 data suggest that changes in management techniques are adopted slowly.
