Evaluation of different microporous filters for the recovery of human adeno- and noroviruses from seawater
Creators: name: Lyman, Whitney
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2005

description: The presence of bacterial enteric pathogens or their indicators does not predict the presence of human enteric viruses in recreational waters. Currently, no validated filter-based method exists for the recovery and quantitative detection of human noro- or adenovirus from seawater. In this study, we evaluated the adsorption-elution characteristics of two negatively charged fiberglass filters (Whatman GF/F and Filterite) and a novel positively charged alumina filter (NanoCeram) for the recovery of noro- and adenovirus in seeded seawater. Percent adsorption and elution were calculated by realtime (RT-)PCR detection of the viruses in the filter eluates. Different elution solutions and contact times were compared for subsequent recovery of the adsorbed viruses. The negatively charged filters had both low adsorption of adenovirus type 2 from seawater (GF/F:26%; Filterite:11%) and low elution of the viruses from the filters (<10%). The positively charged Nanoceram filters adsorbed significantly more virus (>58%) than the negatively charged filters, but effective elution of the viruses from these filters was very poor (<5%) regardless of the type of elution buffer. Further research into improved elution methods or different filters for the recovery of these viral pathogens from seawater is warranted to better monitor health risks associated with exposure to contaminated recreational waters.

Creators: name: Saunders, Hannah
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2005

description: The effectiveness of ultraviolet radiation (UV) from low and medium pressure mercury lamps against relatively UV-resistant adenoviruses in drinking water is uncertain. Therefore, their effectiveness as collimated beams against adenoviruses 5 and 41 was investigated. In buffered saline (BS), log[10]Ad5 reductions at UVdoses of 40, 80, and 120 mJ/cm^2 were 1.8, 2.9, and 3.5, respectively, with LP lamps and 2.9, 3.8, and 4.7, respectively, with MP lamps. Ad41 log[10] reductions at UV doses of 50, 100, and 150 mJ/cm^2 were 0.35, 1.1, and 2.4, respectively with LP and 0.8, 1.6, and 3.4, respectively with MP. Log[10] Ad5 reductions by LP UV doses of 40, 80 and 120 mJ/cm^2 were 1.3, 2.2, and 3.0, respectively in colored natural water (DOC~20mg/L) and 1.6, 3.6, and 4.3 in this same water with 5NTU clay turbidity. These data inform decision-making on UV disinfection guidance for drinking water.

description: In a standard semiconductor laser, electrons and holes recombine via stimulated emission to emit coherent light, in a process that is far from thermal equilibrium. Exciton-polariton condensates -- sharing the same basic device structure as a semiconductor laser, consisting of quantum wells coupled to a microcavity -- have been investigated primarily at densities far below the Mott density for signatures of Bose-Einstein condensation. At high densities approaching the Mott density, exciton-polariton condensates are generally thought to revert to a standard semiconductor laser, with the loss of strong coupling. Here, we report the observation of a photoluminescence sideband at high densities that cannot be accounted for by conventional semiconductor lasing. This also differs from an upper-polariton peak by the observation of the excitation power dependence in the peak-energy separation. Our interpretation as a persistent coherent electron-hole-photon coupling captures several features of this sideband whereas many remain elusive. Understanding the observation will lead to a development in non-equilibrium many-body physics.

title: Machine Learning Emulators for Numerical Weather Prediction—Applications to Parametrization Schemes
Creators: name: Meyer, David
Publisher: name: University of Reading
Year: 2022

description: Weather prediction hinges on mathematical models implemented into software to predict the future state of the atmosphere. Despite remarkable progress, computational constraints and user demands are choking this progress. In this PhD thesis, new machine learning (ML) methods are presented to improve the parametrization of two common schemes used within numerical weather prediction (NWP): radiation and urban land surface. First, a fast and accurate ML emulator for simulating three-dimensional cloud effects as a correction term to a fast parametrization scheme is developed rather than replacing the entire radiation scheme. Second, as ML emulators' training data can be scarce or expensive, a cheap method based on statistical copulas is implemented to generate data like the original across variables and dimensions. Third, the urban land surface model Town Energy Balance (TEB) is coupled to the Weather Research and Forecasting (WRF) model through a modular implementation, verified by an integration test, to evaluate a newly devised urban neural network (UNN) emulator. By training the UNN on the mean output from several urban land surface schemes, the UNN is more accurate, cheaper to run, and simpler to set up than TEB. Furthermore, when coupled to WRF, the UNN is numerically stable with lower errors than the reference WRF-TEB implementation.

Για τον λόγο αυτό, εξετάζονται όλες οι δεδηλωμένες ετυμολογίες του πρώτου βιβλίου, και κατ’ επιλογήν κρίσιμα χωρία του έργου όπου η ετυμολογία αποκτά μείζονα ρόλο. Έτσι το πρώτο κεφάλαιο εστιάζει στα προγραμματικά χωρία του Ιανού και των Αγωναλίων, το δεύτερο κεφάλαιο ασχολείται με τη σταθερή ετυμολόγηση κάθε μήνα που απαντά στην εισαγωγική ενότητα κάθε βιβλίου, και τέλος το τρίτο κεφάλαιο με τις υπόλοιπες ετυμολογίες του 1ου βιβλίου, δηλαδή όσες δεν εντάσσονται στα χωρία του Ιανού και των Αγωναλίων. Συμπερασματικά, ο ποιητής καταφέρνει να εντάξει με ποικίλες τεχνικές την ετυμολογία στο έργο του, η οποία αποτελεί μία όψη της αιτιολογίας, και την αξιοποιεί έντεχνα ως ποιητικό εργαλείο με σκοπό να εμπλουτίσει το ημερολογιακό υλικό του έργου του.
description: The aim of the present thesis is the investigation of etymology in Ovid’s Fasti and more specifically how etymology serves the aetiological dimension of the work. Also how a scientific knowledge is used by the poet in order to successfully incorporate it into his work, presenting it as poetic material. For this reason all the declared etymologies of the first book are examined, and by choice the critical passages of the work where etymology acquires a major role. Thus, the first chapter focuses on the programmatic passages of Janus and the Agonalia, the second chapter deals with the fixed etymology of each month that corresponds to the introductory section of each book, and finally the third chapter handles the rest of the etymologies of the first book, those that not included in the passages of Janus and the Agonalia. In conclusion, the poet manages to incorporate etymology into his Fasti, which is an aspect of aetiology, with various techniques, and artfully uses it as a poetic tool in order to enrich the diary material of his work.
Effectiveness of the LifeStraw as a Personal Point-of-Use Water Purifier

Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2007

description: Point-of-use (POU) water treatment has emerged as a way to immediately and directly combat the reality that >1 billion people lack access to safe water. The LifeStraw is a personal, portable, POU water purifier. This research focused on testing various LifeStraw models in order to determine optimal configuration. Performance was judged on the basis of the ability to reduce microorganisms from water, achieve a total filtered volume of 700 L while maintaining a constant flow rate and realistic pressure, and not leach internal chemical components, specifically iodine and silver, at levels exceeding health-based standards or guidelines. Concentrations of pathogenic microbes were determined in the influent challenge water and LifeStraw filtrates to compute log[10] and percent reductions. Overall log[10] reductions were: for the bacterium, Salmonella typhimurium, >6.0 (99.9999%); for the enteric virus, Poliovirus-1, 1.1-1.4 (92-96%), and for the protozoan parasites, Cryptosporidium parvum and Giardia lamblia, <0.3 (50%). The later LifeStraw models tested consistently achieved a filtration aging volume of 700 L and effluent concentrations of iodine and silver were below standards and guidelines values. Therefore, the LifeStraw is capable of reducing pathogenic bacteria, like Salmonella to levels meeting national and international performance targets of 6.0 log[10] reduction, but log[10] reductions for viruses and protozoan parasites were far below the performance targets of 4.0 and 3.0, respectively. Therefore, some key performance criteria were achieved by LifeStraws but others, especially virus and protozoan reductions, require further research and development for improved performance.

description: We calculate the ground-state properties of unpolarized two-dimensional attractive fermions in the range from few to many particles. Using first-principles lattice Monte Carlo methods, we determine the ground-state energy, Tan's contact, momentum distribution, and single-particle correlation function. We investigate those properties for systems of $N=4,8,...,40$ particles and for a wide range of attractive couplings. As the attractive coupling is increased, the thermodynamic limit is reached at progressively lower $N$ due to the dominance of the two-body sector. At large momenta $k$, the momentum distribution displays the expected $k^{-4}$ behavior, but its onset shifts from $k \simeq 1.8 k^{}_F$ at weak coupling towards higher $k$ at strong coupling.

An Investigation of Residual Coal Tar Mobilization in Water Saturated Porous Media
Creators: name: Fitchett, Ebony V.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2004

description: The presence of dense nonaqueous phase liquids (DNAPLs) in aquifers poses a significant problem. Because DNAPLs slowly dissolve, are toxic, and tend to penetrate deep into the porous medium, they are a source of long-term contamination. Conventional pump-and-treat techniques are inadequate in remediating DNAPL contaminated aquifers. However, thermal treatments and in-situ flushing technologies have shown considerable promise for improving DNAPL recovery. One- and two-dimensional experiments were conducted to investigate several methods, including hot water flushing, surfactant flushing at elevated temperatures, and alcohol flooding in conjunction with a dense brine barrier, as a means of mobilizing and recovering coal tar by decreasing interfacial tension and/or viscosity. A mixture of polycyclic aromatic hydrocarbons (PAH's) was used in the experiments. It was designed to serve as a well-characterized model for coal tar. Results from the hot water and surfactant flushing showed no significant mobilization of the PAH mixture though there were signs of solubilization of the lighter components (e.g., naphthalene). In the experiments using alcohol, significant mobilization and removal of the PAH mixture was observed. The downward mobilization was controlled using a dense brine barrier. This also promoted pooling of the DNAPL which allowed for more efficient removal.

Application of InVitro Cell Culture Assay to Cryptosporidium Parvum Oocysts Inactive by Thermal Processes
Creators: name: Barbee, Susan Lynn

Year: 1998

description: Cryptosporidium is an important waterborne pathogen and its oocysts are very persistent in the environment and very resistant to chemical disinfection. Inactivation of Cryptosporidium parvum oocysts by heat is a potential disinfection process for water, wastewater and biosolids. We studied the kinetics and extent of thermal inactivation of C. parvum oocysts in buffered water at 35°, 49°, 50°, 55° and 60°C, and by thermophilic anaerobic digestion of cow manure at 55°C using mammalian cell culture to quantify oocysts infectivity. Comparisons of infectious oocyst concentrations between untreated controls and thermally treated samples indicated significant losses of oocyst infectivity by higher temperature thermal treatment in both milieu. While there were only minor reductions of oocyst infectivity in buffered water after 24 hours at 23° and 35°C, temperatures of 55° and 60°C reduced oocyst infectivity by 99.9% within 60 minutes. Exposure at 55°C in anaerobically digested manure for 60 minutes reduced oocyst infectivity by 99.9%, but in the untreated manure oocyst infectivity was stable for many hours at 23°C. These data demonstrate that the infectivity of C. parvum oocysts is rapidly and extensively reduced in water and bovine manure at thermophilic temperatures as low as 55°C.

The analysis is supplemented by deep simulative investigations able to provide both a preliminary overview of the experimental scenario and a posteriori validation of the achieved results. As a first step, the far-field OAM communication link is tested at various frequencies and the corresponding link budget is studied by means of an angular scan generated by the rotation of the receiving system. Then, on the same site, two digital television signals encoded as OAM modes ($\ell$=1 and $\ell$=-1) are simultaneously transmitted at a common frequency of 198.5 MHz with good mode insulation.

Determination of Trichinella Spiralis Specific IgM and IgG Antibody Titers and Total IgE Concentration in 2,3,7,8-Tetrachlorodibenzo-P-Dioxin Exposed Rats
Creators: name: Loftus, Sarah C.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries

description: Immunotoxic chemicals are a concern because of the role the immune system plays in maintaining health. The immunotoxicity of TCDD has been well documented as the immune system is highly sensitive to TCDD exposure (Smialowicz et al., 1994). In host resistance studies, functional immune system changes following TCDD exposure have been demonstrated to lead to an increase in susceptibility to bacterial, viral and parasitic diseases. In order to investigate whether TCDD treatment decreased parasite antigen-specific antibody responses, sera from adult male F344 rats dosed with 30 μg/kg TCDD or corn oil and infected with T. spiralis were analyzed at days 7, 9, 11, 14, and 28 post infection by ELISA for T. spiralis specific IgM and IgG antibody titers and total IgE concentration. An enhancement in the treated group of the IgM antibody response at days 7 and 14 (p<0.05) was observed. A slight suppression of the day 9 IgM antibody response was also noted in the treated group (p<0.05). Additionally, the IgG day 9 titer reflected a suppressed antibody response in the treated group (p<0.05). No other treatment related effects were observed in the adult rats. Aged rats were also investigated under the same parameters at days 11 and 28 post infection. No observable changes in antibody levels were recorded for the aged rats. These data were generated to further evaluate the link between decreased parasite antigen specific antibody responses and treatment with TCDD in rats.

Mixed Integer Programming Model for Optimal Operation of the Durham, North Carolina Water Reservoir System
Creators: name: Fragapane, Philip
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1996

description: The Durham, North Carolina water reservoir system is a complicated system of two raw water reservoirs in independent watersheds, four main pumping stations, many pumps of three different types, and two treatment plants, each with terminal reservoirs. The reservoir systems meets an average water demand of about 25 million gallons per day. Optimal operation of the system to meet system demands for treated water, while minimizing operating costs. Because of the many decisions involved in the operation of such a complex system, determining the optimal operation is not obvious. One approach to optimizing operation is to formulate a mathematical model of the system. Such a model may be used to determine the present and future optimal operation of the system. It can serve as a tool to gain experience in system operation by varying system inputs and examining optimal solution behavior. This report describes a mixed integer programming model of the Durham reservoir system. It begins with a description of the system and each of its components. It details the development of the model, describing its objective function, variables and constraints. A solution is presented using actual system inputs (demands, inflows, etc.) from 1994. Finally, the report identifies the differences between the "optimal" and actual pumping decisions made in 1994, and discusses ways that operational costs might be reduced.

We compared the observed results with a binomial distribution considering that the probabilities of winning or losing a point are equal. Using a $χ^2$ test we found that, excepting some players, the greatest part of the results agrees with our hypothesis that there is no hidden strategy and the points in tiebreaks are merely aleatory.

description: Surface plasma waves (SPWs) have been extensively studied in the past two decades with a promise for many applications. However, the effort has so far been met with limited success. It is widely believed that a major caveat lies with the energy losses experienced by SPWs during their propagation. To compensate for the losses, amplifiers have been designed, which are all extrinsic and need an external agent to supply the energy. Here we theoretically show that there exists an intrinsic amplification channel for SPWs in the collision-less limit. We pin down the origin of this channel and analytically calculate the amplification rate. Our finding unveils a hitherto unchartered yet fundamental property of SPWs and may bear far-reaching practical consequences.

description: MEG/EEG are non-invasive imaging techniques that record brain activity with high temporal resolution. However, estimation of brain source currents from surface recordings requires solving an ill-posed inverse problem. Converging lines of evidence in neuroscience, from neuronal network models to resting-state imaging and neurophysiology, suggest that cortical activation is a distributed spatiotemporal dynamic process, supported by both local and long-distance neuroanatomic connections. Because spatiotemporal dynamics of this kind are central to brain physiology, inverse solutions could be improved by incorporating models of these dynamics. In this article, we present a model for cortical activity based on nearest-neighbor autoregression that incorporates local spatiotemporal interactions between distributed sources in a manner consistent with neurophysiology and neuroanatomy. We develop a dynamic Maximum a Posteriori Expectation-Maximization (dMAP-EM) source localization algorithm for estimation of cortical sources and model parameters based on the Kalman Filter, the Fixed Interval Smoother, and the EM algorithms. We apply the dMAP-EM algorithm to simulated experiments as well as to human experimental data. Furthermore, we derive expressions to relate our dynamic estimation formulas to those of standard static models, and show how dynamic methods optimally assimilate past and future data. Our results establish the feasibility of spatiotemporal dynamic estimation in large-scale distributed source spaces with several thousand source locations and hundreds of sensors, with resulting inverse solutions that provide substantial performance improvements over static methods.
Acute Renal and Hepatic Toxicity of Bromodichloromethane (BDCM) in F-344 Rats Following Administration in Different Dosing Vehicles
Creators: name: Lilly, Patrick D.

Year: 1992

description: BDCM, a water disinfection byproduct, was administered by gavage at 0, 200, and 400 mg/kg in either corn oil or 10% Emulphor to 90-day-old F-344 male rats. Urine was collected from 0-6, 6-12, 12-24, 24-36, and 36-48 hours. Animals were killed at 24 or 48 hr, and serum collected. In the high dose groups for both vehicles after 48 hours, significant increases were observed in serum aspartate aminotransferase (AST), lactate dehydrogenase (LDH), blood urea nitrogen (BUN), cholesterol and bile acids. At the apparent time of peak hepatotoxicity (48 hours), 400 mg BDCM/kg caused significantly greater elevations in AST, creatinine, and bile acids when administered in corn oil than in 10% Emulphor. Significant interactions between dose and vehicle of administration were noted for serum enzymes AST, ALK, and LDH, indicating that vehicle differences observed in BDCM hepatotoxicity may be dose dependent. At 200 mg/kg, the only significant response of a serum enzyme was a slight increase in LDH following aqueous administration of BDCM. In contrast to the virtual lack of effects on liver function enzymes at 200 mg/kg, urinary enzymes were dramatically elevated at the low dose in both vehicles. At 24 hours, BDCM increased urine ALT (33%), AST (390%), LDH (300%), and alkaline phosphatase (ALK) (230%) in the low dose corn oil group with respective increases of 75%, 590%, 540%, and 380% in the 10% Emulphor group. Significant vehicle differences were noted for urinary AST and total protein at the 200 mg/kg dose after 36 hours and glucose at the high dose level at 48 hours. Significant interactions between BDCM dose and dosing vehicle were observed for urinary AST, LDH, and total protein at 36 hours post-gavage and total protein at 24 hours, suggesting again that vehicle effects noted in BDCM nephrotoxicity may be dependent on dose. At 400 mg/kg, the time to peak nephrotoxicity appeared greater with corn oil than with the aqueous vehicle. These data suggest that BDCM is more acutely hepatotoxic when administered in corn oil than in an aqueous vehicle and further suggest that the kidney may be a more sensitive indicator of BDCM toxicity than the liver.
The Privatization of Social Work: A Deviation or a Logical Progression?
Creators: Benn, Jenna
Publisher: name: Columbia University

Subjects: Social service

description: Since the 1980s, social workers have increasingly left the service of the public sector and entered into private practice. A substantial number of today’s social workers practice for-proﬁt client-based therapy rather than agency-based public service. These recent changes are causing critics to question whether social work’s new focus on for-proﬁt services has deviated from social work’s original purpose to forge allegiances with the poor, the disadvantaged, and the oppressed. Is this change in focus an abandonment of social work’s historical principles? Or is it simply a modern and logical evolution? This paper examines the debate between private and public social work practice. It describes how social work historically emerged and evolved on two interconnected fronts, one with a focus on change at the community level, and one with a focus on change at the individual level. This paper posits that the two approaches are not irreconcilable and that healthy debate has led, and continues to lead, the profession forward.

The Sibling Relationship in Foster Care: Policy Implications

description: The majority of children placed into foster care are separated from their siblings upon entering the child welfare system. Some research suggests that siblings enjoy more stable home environments and fewer behavioral problems when placed together in care. The sibling relationship may provide stability, consistency, and unconditional positive regard to the children most at risk for poor outcomes such as anxiety, depression, low self-esteem, and loss of identity. This paper argues that foster care and child welfare agencies must institute the changes necessary to make sibling relationships a priority. Recommendations for integrating the protection of sibling relationships in the placement process are proposed.

description: We describe a new class of positive linear discrete-time switching systems for which the problems of stability or stabilizability can be resolved constructively. This class generalizes the class of systems with independently switching state vector components. The distinctive feature of this class is that, for any system from this class, its components or blocks can be arbitrarily connected in parallel or in series without loss of the `constructive resolvability' property. It is shown also that, for such systems, it is possible to build constructively the individual positive trajectories with the greatest or the lowest rate of convergence to the zero.

Contrasting Pathways for Activation of Two Cyclopentafused PAH in the Ames Assay: Identification of Metabolites of Benz[j]Aceanthrylene and Cyclopentafused Benzo[e]pyrene

description: To determine the contribution of the diol-epoxide to the genotoxicity of benz[j]aceanthrylene (BjAA), the mutagenic activity of BjAA and its bay-region metabolites were evaluated in the Ames assay. BjAA, the 9,10-oxide, and the 9,lO-dihydrodiol are indirect acting mutagens with specific activities of 12.9 rev/nmole, 5.6 rev/nmol, and 9.4 rev/nmole, respectively. The 9,10-dihydrodiol-7,8-oxide was direct acting having the same activity as the parent compound, BjAA. Metabolism studies using Aroclor 1254 induced rat liver S9 were conducted on the BjAA-9,10-dihydrodiol metabolite. Four metabolites were isolated. Three metabolites were identified as 1,2,9,10-tetrahydro-l,2,9,10-tetrahydroxy-BjAA, 7,8,9,10-tetrahydro-7,8,9,10-tetrahydroxy-BJAA and the 9,10-dihydroxy-BjAA. The fourth metabolite was tentatively identified as BJAA-9,10-dihydrodiol-2-one. Similarly, the metabolism of cyclopentafused benzo[e]pyrene (cpBeP) was also investigated to determine whether the previously observed mutagenic activity of this compound was due to metabolism at the bay-region or the etheno bridge. Only one major metabolite was observed, the 3,4-dihydrodiol cpBeP. Additional minor metabolites were isolated, but not enough material was available to identify them. Oxidation occurs at the cyclopentafused ring for both BjAA and cpBeP when incubated with rat liver 59. This structure is of importance when considering mutagenic activation of a compound, and is an exception to the bay-region theory proposed by Jerina and colleagues.
