Effectiveness Of Aqueous Chlorine Dioxide In Minimizing Food Safety Risk Associated With Salmonella, E. Coli O157:H7, And Listeria Monocytogenes On Sweet Potatoes, Phillip Luu, Vijay Singh Chhetri, Marlene E. Janes, Joan M. King, Achyut Adhikari

Faculty Publications

Sodium hypochlorite (NaOCl) is a commonly used sanitizer in the produce industry despite its limited effectiveness against contaminated human pathogens in fresh produce. Aqueous chlorine dioxide (ClO2) is an alternative sanitizer offering a greater oxidizing potency with greater efficacy in reducing a large number of microorganisms. We investigated the effect of aqueous chlorine dioxide treatment against human pathogens, Salmonella, Escherichia coli O157:H7, and Listeria monocytogenes seeded on sweet potatoes. Sweet potatoes were spot inoculated (4.2 to 5.7 log CFU/cm2) with multi-strain cocktails of Salmonella spp., E. coli O157:H7, and L. monocytogenes and treated for 10-30 min with 5 ppm aqueous …

Beyond The Social Cost Of Carbon: Negative Emission Technologies As A Means For Biophysically Setting The Price Of Carbon, Brian F. Snyder Sep 2020

Beyond The Social Cost Of Carbon: Negative Emission Technologies As A Means For Biophysically Setting The Price Of Carbon, Brian F. Snyder

Faculty Publications

The social cost of carbon (SCC) is an estimate of the costs that society will incur because of the emission of one tonne of CO2. Because of the large uncertainties in the effects of climate change and the subjectivity of the discount rate, estimates of SCC range widely, from − 10.2 to 105 213$ t−1 in 2010 USD. Despite this range, the SCC has been used or proposed as a basis for a wide variety of policymaking including cost–benefit analysis and carbon taxes. The SCC suffers from several practical and philosophical weaknesses: it is anthropocentric, it neglects the acidification …

Efficient Solvent-Free Microwave Irradiation Synthesis Of Highly Conductive Polypropylene Nanocomposites With Lowly Loaded Carbon Nanotubes, Xingru Yan, Jingjing Liu, Mojammel Alam Khan, Stephen Sheriff, Sravanthi Vupputuri, Rajib Das, Luyi Sun, David P. Young, Zhanhu Guo

Faculty Publications

It was well established that microwave radiation was utilized initially to enhance the electrical conductivity of polymer nanocomposites (PNCs) by introducing carbon nanotubes (CNTs) without using any solvent. High electrical conductivity was obtained in polypropylene (PP) nanocomposites with low CNTs loading levels. Under an inert gas protection, the CNTs were heated through the transformation of electromagnetic energy into mechanical vibrations. The surface of PP was easily molten by the heat generated by CNTs, then a well-formed CNTs network was built under proper microwave treatment period and subsequent hot pressing. CNTs loading levels and processing temperatures played an important role in …

Irreducibility Of The Fermi Surface For Planar Periodic Graph Operators, Wei Li, Stephen P. Shipman Sep 2020

Irreducibility Of The Fermi Surface For Planar Periodic Graph Operators, Wei Li, Stephen P. Shipman

Faculty Publications

We prove that the Fermi surface of a connected doubly periodic self-adjoint discrete graph operator is irreducible at all but finitely many energies provided that the graph (1) can be drawn in the plane without crossing edges, (2) has positive coupling coefficients, (3) has two vertices per period. If “positive” is relaxed to “complex,” the only cases of reducible Fermi surface occur for the graph of the tetrakis square tiling, and these can be explicitly parameterized when the coupling coefficients are real. The irreducibility result applies to weighted graph Laplacians with positive weights.

Behavioral Strategies During Incubation Influence Nest And Female Survival Of Wild Turkeys, Ashley K. Lohr, James A. Martin, Gregory T. Wann, Bradley S. Cohen, Bret A. Collier, Michael J. Chamberlain Sep 2020

Behavioral Strategies During Incubation Influence Nest And Female Survival Of Wild Turkeys, Ashley K. Lohr, James A. Martin, Gregory T. Wann, Bradley S. Cohen, Bret A. Collier, Michael J. Chamberlain

Faculty Publications

Females must balance physiological and behavioral demands of producing offspring with associated expenditures, such as resource acquisition and predator avoidance. Nest success is an important parameter underlying avian population dynamics. Galliforms are particularly susceptible to low nest success due to exposure of ground nests to multiple predator guilds, lengthy incubation periods, and substantive reliance on crypsis for survival. Hence, it is plausible that nesting individuals prioritize productivity and survival differently, resulting in a gradient of reproductive strategies. Fine-scale movement patterns during incubation are not well documented in ground-nesting birds, and the influence of reproductive movements on survival is largely unknown. …

Phyr: Anrpackage For Phylogenetic Species-Distribution Modelling In Ecological Communities, Daijiang Li, Russell Dinnage, Lucas A. Nell, Matthew R. Helmus, Anthony Ives Sep 2020

Phyr: Anrpackage For Phylogenetic Species-Distribution Modelling In Ecological Communities, Daijiang Li, Russell Dinnage, Lucas A. Nell, Matthew R. Helmus, Anthony Ives

Faculty Publications

Model-based approaches are increasingly popular in ecological studies. A good example of this trend is the use of joint species distribution models to ask questions about ecological communities. However, most current applications of model-based methods do not include phylogenies despite the well-known importance of phylogenetic relationships in shaping species distributions and community composition. In part, this is due to a lack of accessible tools allowing ecologists to fit phylogenetic species distribution models easily. To fill this gap, therpackagephyr(pronounced fire) implements a suite of metrics, comparative methods and mixed models that use phylogenies to understand and predict community composition and other …

Faculty Publications

OBJECTIVES: Increasing antimicrobial resistance rates limit empirical antimicrobial treatment options for Gram-negative bloodstream infections (GN-BSI). However, antimicrobial resistance may be predicted based on patient-specific risk factors using precision medicine concepts. This retrospective, 1:2 matched cohort examined clinical outcomes in hospitalized adults without major risk factors for antimicrobial resistance receiving empirical fluoroquinolones or broad-spectrum beta-lactams (BSBL) for GN-BSI at Prisma Health-Midlands hospitals in Columbia, SC, USA from January 2010 through June 2015. METHODS: Multivariable logistic regression was used to examine early treatment failure at 72-96 h from GN-BSI. Cox proportional hazards regression was used to examine 28-day mortality and hospital length …

The Impact Of Service Firm’S Environmentally Friendly Reputation In The Context Of Revenue Management, Choongbeom Choi, Miyoung Jeong Ph.D. Sep 2020

The Impact Of Service Firm’S Environmentally Friendly Reputation In The Context Of Revenue Management, Choongbeom Choi, Miyoung Jeong Ph.D.

Faculty Publications

In revenue management practice, customers’ perceived fairness is a critical issue. Prior research examined the effect of revenue management on customers’ perceptions of fairness by implementing two different conditions: fencing and framing. In this study, the authors evaluated the role of a service firm’s environmentally friendly reputation under the conditions of fencing and framing. Results indicated that an environmentally friendly reputation only moderated the effect of framing on perceived fairness. In particular, when the firm had a poor reputation, framing as a discount rather than framing as a surcharge increased customers’ fairness perceptions. When the firm had a good reputation, …

Making It Free And Easy: Exploring The Effects Of North Carolina College Application Week On College Access, Ashley B. Clayton, Paul D. Umbach Sep 2020

Making It Free And Easy: Exploring The Effects Of North Carolina College Application Week On College Access, Ashley B. Clayton, Paul D. Umbach

Faculty Publications

This study uses a series of panel models to explore the effect of North Carolina (NC) College Application Week (CAW) and free college applications during that week on the number of applications colleges receive and number of low-income students who matriculate. Our models suggest that NC saw an increase in applications and low-income student enrollments after the implementation of CAW, but these increases largely occurred at private col-leges, seemingly shifting numbers from public universities. We find that the private colleges offering free applications during CAW experienced increases in the total number of both college applications received.

Process Controls Of The Live Root Zone And Carbon Sequestration Capacity Of The Sundarbans Mangrove Forest, Bangladesh, Edwin J. Bomer, Carol A. Wilson, Tracy Elsey-Quirk

Faculty Publications

The conservation of coastal wetland ecosystems, like mangrove forests and salt marshes, represents a critical strategy for mitigating atmospheric emissions and climate change in the 21st century. Yet the existence of these environments is threatened by human-induced disturbances, namely deforestation and accelerated sea-level rise. Coastal systems maintain surface elevation in response to sea-level rise through a combination of physical and biological processes both above and below the ground surface. The quantification and relative contribution of belowground process controls (e.g., seasonal water content, organic matter decomposition) on surface elevation change is largely unexplored but crucial for informing coastal ecosystem sustainability.

High-Pressure Ignition Delay Time Measurements Of A Four-Component Gasoline Surrogate And Its High-Level Blends With Ethanol And Methyl Acetate, Sean P. Cooper, Olivier Mathieu, Ingmar Schoegl, Eric L. Petersen

Faculty Publications

Ignition delay times of a gasoline surrogate (iso-octane/toluene/n-heptane/1-hexene at 55/25/15/5% by liquid volume, developed in McCormick et al. 2017) with high-level bioblendstock-gasoline surrogate blends (50% and 85% biofuel by liquid volume of each ethanol and methyl acetate) were collected behind reflected shock waves. Post-reflected-shock temperatures ranged from 968 to 1361 K at pressures of about 4, 10, 25, and 50 atm. Data were collected for real fuel–air mixtures at fuel lean and stoichiometric conditions (φ = 0.5, 1.0) with focus on the more-practical, fuel-lean conditions. Ignition delay times were measured from OH* chemiluminescence around 307 nm using an endwall diagnostic. …

Effects Of Coupled Consolidation And Overwash Processes On A Low-Lying Headland System, Brian D. Harris, Cody Johnson, Navid H. Jafari, Qin Chen, Celalettin E. Ozdemir

Faculty Publications

Coastal barrier islands serve as the first line of defense against storm-induced hazards and coastal erosion. Due to sea-level rise and more frequently occurring storms, barrier island restoration and rehabilitation have become more important for coastal protection. The current-state-of-the practice for simulation of barrier island restoration design mostly overlooks consolidation as one of the governing processes. However, low-lying barrier islands, especially those built on loose deltaic or estuarine deposits, may further lose elevation due to consolidation and become more vulnerable to erosion. This study investigates the impacts of consolidation without overwash, overwash without consolidation, and coupled consolidation and overwash in …

Animals with complex life cycles have traits related to oviposition and juvenile survival that can respond to environmental factors in similar or dissimilar ways. We examined the preference-performance hypothesis (PPH), which states that females lacking parental care select juvenile habitats that maximize fitness, for two ubiquitous mosquito species, Aedes albopictus and Culex quinquefasciatus. Specifically, we examined if environmental factors known to affect larval abundance patterns in the field played a role in the PPH for these species. We first identified important environmental factors from a field survey that predicted larvae across different spatial scales. We then performed two experiments, …

© 2020 by the authors. Licensee MDPI, Basel, Switzerland. Ticks are blood-feeding arthropods and transmit a variety of medically important viral, bacterial, protozoan pathogens to animals and humans. Ticks also harbor a diverse community of microbes linked to their biological processes, such as hematophagy, and hence affect vector competence. The interactions between bacterial and/or protozoan pathogens and the tick microbiome is a black-box, and therefore we tested the hypothesis that the presence of a protozoan or bacterial pathogen will alter the microbial composition within a tick. Hence, this study was designed to define the microbial composition of two tick species, …
