description: The high excitation planetary nebula, NGC 6302, has been imaged in two far-ultraviolet (FUV) filters, F169M (Sapphire; λ$_{\rm eff}$: 1608 Å) and F172M (Silica; λ$_{\rm eff}$: 1717 Å) and two NUV filters, N219M (B15; λ$_{\rm eff}$: 2196 Å) and N279N (N2; λ$_{\rm eff}$: 2792 Å) with the Ultra Violet Imaging Telescope (UVIT). The FUV F169M image shows faint emission lobes that extend to about 5 arcmin on either side of the central source. Faint orthogonal collimated jet-like structures are present on either side of the FUV lobes through the central source. These structures are not present in the two NUV filters nor in the FUV F172M filter. Optical and IR images of NGC 6302 show bright emission bipolar lobes in the east-west direction with a massive torus of molecular gas and dust seen as a dark lane in the north-south direction. The FUV lobes are much more extended and oriented at a position angle of 113°. They and the jet-like structures might be remnants of an earlier evolutionary phase, prior to the dramatic explosive event that triggered the Hubble type bipolar flows approximately 2200 years ago. The source of the FUV lobe and jet emission is not known, but is likely due to fluorescent emission from H$_2$ molecules. The cause of the difference in orientation of optical and FUV lobes is not clear and, we speculate, could be related to two binary interactions.

description: In cosmology minisuperspace models are described by nonlinear time-reparametrization invariant systems with a finite number of degrees of freedom. Often these models are not explicitly integrable and cannot be quantized exactly. Having this in mind, we present a scheme for the (approximate) quantization of perturbed, nonintegrable, time-reparametrization invariant systems that uses (approximate) gauge invariant quantities. We apply the scheme to a couple of simple quantum cosmological models.

Race and Sex Differences in the Association between Red and Processed Meat Consumption and Metabolic Profile in Coronary Artery Risk Development in Young Adults (CARDIA) Study (2005-2006)
Creators: name: Shetye, Aditya
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2024

description: We sought to investigate whether self-reported race and sex modifies the association between red and processed meat (RPM) consumption, a dietary component associated with cardiometabolic disease (CMD) risk, and metabolic profile. We studied 2,841 Black and White men and women (mean age: 45 years; 45% Black race; 57% women) at the year 20 follow-up (2005-06) of the U.S.-based CARDIA study. We ran race- and sex-stratified OPLS-R models to evaluate ability of metabolite combinations to explain variance in RPM consumption. We also iteratively fit each metabolite peak onto RPM consumption and identified pathways with more activity than expected.  We found metabolite combinations of White participants and men explained more variance in RPM consumption, as compared to metabolite combinations of Black participants and women, respectively. We observed differential metabolic activity by self-reported race, but not sex, than expected by chance. Identified pathways may reveal mechanistic drivers of racial disparities in diet-CMD associations.

The Prevalence of At-Risk Female Athletes for Developing Low Energy Availability in Division I and III Collegiate Athletics
Creators: name: Bacon, Caitlin Nicole
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2024

description: Low energy availability (LEA) is a disorder that can perpetuate into other negative health effects, such as REDs, and is prevalent within the collegiate female athletic community.¹ The primary purpose of this study was to determine if a difference exists in the prevalence of at-risk female athletes for developing LEA between NCAA Division I (DI)  and Division III (DIII) athletics. A secondary purpose was to analyze the pattens and themes reported by the participants on injury and menstruation. Participants completed an electronic version of the Low Energy Availability in Female Athletes Questionnaire (LEAF-Q). Questionnaire scores placed participants in the at-risk or not-at-risk category for developing LEA. 72% of DI and 64% of DIII participants were at-risk which is consistent with the literature. These percentages were not statistically significant indicating that while it is widely thought that DI athletics are more challenging than DIII, there are similar athlete demands.

description: We consider $m$ spinless Fermions in $l > m$ degenerate single-particle levels interacting via a $k$-body random interaction with Gaussian probability distribution and $k <= m$ in the limit $l$ to infinity (the embedded $k$-body random ensembles). We address the cases of orthogonal and unitary symmetry. We derive a novel eigenvalue expansion for the second moment of the Hilbert-space matrix elements of these ensembles. Using properties of the expansion and the supersymmetry technique, we show that for $2k > m$, the average spectrum has the shape of a semicircle, and the spectral fluctuations are of Wigner-Dyson type. Using a generalization of the binary correlation approximation, we show that for $k << m << l$, the spectral fluctuations are Poissonian. This is consistent with the case $k = 1$ which can be solved explicitly. We construct limiting ensembles which are either fully integrable or fully chaotic and show that the $k$-body random ensembles lie between these two extremes. Combining all these results we find that the spectral correlations for the embedded ensembles gradually change from Wigner-Dyson for $2k > m$ to Poissonian for $k << m << l$.

description: Trapping of bodies by waves is extended from electromagnetism to gravity. It is shown that gravitational waves endowed with angular momentum may accumulate near its axis all kinds of cosmic debris. The trapping mechanism in both cases can be traced to the Coriolis force associated with the local rotation of the space metric. The same mechanism causes the Trojan asteroids to librate around the Sun-Jupiter stable Lagrange points $L_4$ and $L_5$. Trapping of bodies in the vicinity of the wave center could also be related to the formation of galactic jets.

Comparing Head Impact Biomechanics During Different Drill Types in Collegiate Offensive and Defensive Linemen
Creators: name: Pattison, Carly
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2025

description: This study prospectively observed ten collegiate football linemen performing individual and team practice drills during the fall season. A total of 2,242 head impacts were recorded by the Head Impact Telemetry System, validated through video data, and categorized into one of seven standardized drill types. Results from linear mixed models indicated drill type as a main effect for peak linear acceleration (p = 0.001), peak rotational acceleration (PRA) (p = 0.023), and risk-weighted exposure (p = 0.040); therefore, subsequent pairwise comparisons were performed. Except for 1-on-1 drills, inside run recorded significantly greater impact kinematics compared to all drill types, and defensive linemen had greater PRA than offensive linemen. Offensive linemen sustained a higher cumulative load of impacts when compared to defensive linemen. An understanding of how position- and drill-specific responsibilities influence head impact kinematics may provide insight to practical strategies to alter drill execution without sacrificing the integrity of practice.
PARTISAN DIVIDE AND POLARIZATION IN GEORGIA
Creators: name: Mukasashvili, Nika
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2024

description: Polarization and partisan divide play a detrimental role in Georgia’s contemporary politics. In this thesis, I analyze the patterns of negative partisanship, the partisan divide, and the interpersonal dimensions of affective polarization in Georgian politics. This topic is crucial for the region, as the young democracy is on the path to Euro-integration but has yet to consolidate democracy efficiently. I investigate how party attachment and division affect individuals’ comfort when interacting with voters from opposing parties. Furthermore, I am eager to explore whether voters’ behavior is associated with the policy preferences and issue concerns of the parties. To explore these dimensions, I use quantitative methods and recent polls to conduct logistic regression models for the analysis. I believe this research will be a new cornerstone in partisanship studies in Georgia.

This model is related to the continuum limit of the Ising model with random bonds via the replica method. We discuss how this method may be useful in calculating correlation functions of physical operators. The identification of non-perturbative fixed points of the O(N) Gross-Neveu model is pursued by its mapping to a WZW model.

description: Here, we show that the electronic properties of a surface-supported 2-dimensional (2D) layer structure can be self-texturized at the nanoscale. The local electronic properties are determined by structural relaxation processes through variable adsorption stacking configurations. We demonstrate that the spatially modulated layer-buckling, which arises from the lattice mismatch and the layer/substrate coupling at the GdAu2/Au(111) interface, is sufficient to locally open an energy gap of ~0.5eV at the Fermi level in an otherwise metallic layer. Additionally, this out-of-plane displacement of the Gd atoms patterns the character of the hybridized Gd-d states and shifts the center of mass of the Gd 4f multiplet proportionally to the lattice distortion. These findings demonstrate the close correlation between the electronic properties of the 2D-layer and its planarity. We demonstrate that the resulting template shows different chemical reactivity which may find important applications.

Subjects: classificationCode: 40
subject: Engineering

description: This thesis performs an analysis on electrodialysis for desalination and its integration with renewable energy systems. Firstly, a literature review is performed, which summarizes the fundamental concepts of electrodialysis and its integration with renewable energy sources. It covers photo electrodialysis, photovoltaic-assisted electrodialysis, reversible electrodialysis and wind energy-driven electrodialysis. Secondly, a thermodynamic model of a combined photo-electrodialysis-chloralkali system for desalination is developed. The waste brine stream from an electrodialysis unit is sent to a chloralkali reactor to produce H2, Cl2, and NaOH. Photoactive materials and photovoltaic panels are utilized to provide the required energy for the process. The specific energy requirements for the electrodialysis and chloralkali units are found to be 1.225 kWh/m3 of freshwater and 2.5 kWh/kg Cl2. The overall combined system energy and exergy efficiencies are found to be 23.93% and 33.14%, respectively. Additionally, a solar pond-assisted reverse osmosis-electrodialysis system to produce freshwater and a hydroponic fertilizer solution for sustainable desalination and waste recovery is designed and thermodynamically modelled. The electrodialysis unit is integrated to recover Mg2+, Ca2+ and SO42- ions from the reverse osmosis waste. A solar pond with an organic Rankine cycle is also integrated to produce the electricity required. The overall energy and exergy efficiencies of the integrated system are found to be 20.36% and 2.546%, respectively. Finally, a life cycle assessment is carried out on a photo-electrodialysis process to quantify the environmental impacts for producing 1 m3 of freshwater. The life cycle impact assessment results are found to be 0.127 kg CO2-Eq, 6.41 x 10-4 kg SO2-Eq, 4.04 x 10-5 kg phosphate-Eq, 1.01 x 10-3 kg DCB-Eq and 33.7 kg DCB-Eq for global warming potential, acidification, eutrophication, freshwater aquatic ecotoxicity and marine aquatic ecotoxicity, respectively. Finally, a sensitivity analysis is performed to observe how various energy inputs (conventional and renewables) into the process affect the selected environmental impacts.

description: We present some properties of (not necessarily linear) positive maps between $C^*$-algebras. We first extend the notion of Lieb functions to that of Lieb positive maps between $C^*$-algebras. Then we give some basic properties and fundamental inequalities related to such maps. Next, we study $n$-positive maps ($n\geq 2$). We show that if for a unital $3$-positive map $Φ: \mathscr{A}\longrightarrow\mathscr{B}$ between unital $C^*$-algebras and some $ A\in \mathscr{A}$ equality $Φ(A^*A)= Φ(A)^* Φ(A)$ holds, then $Φ(XA)=Φ(X)Φ(A)$ for all $X \in \mathscr{A}$. In addition, we prove that for a certain class of unital positive maps $Φ: \mathscr{A}\longrightarrow\mathscr{B}$ between unital $C^*$-algebras, the inequality $Φ(αA)\leqαΦ(A)$ holds for all $ α\in [0,1]$ and all positive elements $ A\in \mathscr{A}$ if and only if $Φ(0)=0$. Furthermore, we show that if for some $α$ in the unit ball of $\mathbb{C}$ or in $\mathbb{R}_+$ with $|α|\neq 0,1$, the equality $Φ(αI)=αI$ holds, then $Φ$ is additive on positive elements of $\mathscr{A}$. Moreover, we present a mild condition for a $6$-positive map, which ensures its linearity.

We present the design and first results for the followup procedure of the {\tt Polgraw} all-sky search pipeline: a coherent search for almost-monochromatic gravitational-wave signals in several-day long time segments using the $F$-statistic method followed by the coincidences between the candidate signals. Approximate parameters resulting in these two initial steps are improved in the final followup step, in which the signals from detectors are studied separately, together with the network combination of them, and the true parameters and signal-to-noise values are established.

Characterization of Physical Activity Levels and Modes in College-age Native American Adults
Creators: name: Nez, Nevaeh Rose
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2024

description: The purpose of this study was to evaluate the physical activity (PA) practices of college-aged Native American (NA) adults. Seventy-seven NA adults (18-24 yrs) completed an electronic survey and reported 196.7±303.8 min/wk of PA. However, only 42% achieved the CDC-recommended PA level for moderate and/or vigorous activity. The most common modes of PA were walking (69%), dance (41%), and aerobics (40%). There was no significant difference in total PA between individuals living in different environments (e.g., on reservation, on campus) (p=0.388-0.569), between participants of different tribal regions (p=0.461-0.503), or between varying levels of income (p=0.614) or educational attainment (p=0.825). Environment significantly influenced dance min/wk and 69% of participants reported PA was emphasized in their cultural practices. With more than 50% of participants not meeting PA guidelines, these findings support the need to develop interventions that incorporate a cultural component (e.g., traditional dance) to improve PA participation in college-age Native adults.

The constraints leading to the submodel explore a decomposition of SU(2) with a complex field parametrizing the symmetric space SU(2)/U(1) and a real field in the direction of U(1). We demonstrate that the Skyrmions of topological charges $\pm 1$ belong to such integrable sector of the theory. Our results open ways to the development of exact methods, compensating for the non-existence of a BPS type sector in the Skyrme theory.

description: ABSTRACT      Margaret I. Damaré: COMPARING THE EFFECTS OF PROLONGED SITTING WITH WALKING AND PEDALING INTERRUPTION ON ARTERIAL STIFFNESS IN ADULTS AT RISK FOR CARDIOVASCULAR DISEASE      (Under the direction of Erik Hanson)      Prolonged sedentary behavior (SB) increases arterial stiffness (AS), indicative of cardiovascular disease (CVD) risk. Current SB interruption recommendations lack specificity. This study assessed efficacy and acceptability of two SB interruption strategies (walking and seated pedaling) in older adults at risk for CVD. The randomized controlled cross-over trial recruited 18 participants (55.6% female, age:64.2+5.3 years, 30.3+3.8 kg/m2) with ≥2 CVD risk factors. Participants completed ‘Familiarization’, ‘Walk’, ‘Pedal’, and ‘Control’ visits and an exit questionnaire. Experimental visits included 2.3 hours sitting with or without 5-minute interruptions every 30 minutes. No significant interaction (p=.404) or main (Condition:p=.327, Time:p=.924) effects were observed on carotid-to-femoral pulse wave velocity (measure of AS). Heart rate significantly decreased over time (p=.013). Thematic analysis of questionnaires revealed high participant acceptability for the interruption design. These findings, despite limited efficacy in older adults at risk for CVD, offer valuable insights into interruption acceptability, guiding future targeted SB interruption strategies.

description: We derive the hydrodynamic equations of motion of solid and supersolid 4He, that describe the collective modes of these phases. In particular, the usual hydrodynamics is modified in such a way that it leads to the presence of a propagating instead of a diffusive defect mode. The former is appropriate for a quantum crystal and observed in recent experiments. Furthermore, we find that in supersolid helium there are two additional modes associated with the superfluid degrees of freedom. The observation of these additional modes is a clear experimental signature of the supersolid phase.

The Intersection of Total and Wildland Fire-Attributed PM2.5 Exposure Disparities in the United States
Creators: name: Rice, Richard Byron
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2024

description: Wildland fire smoke exposure is an emerging public health threat, in part due to climate change. Previous research demonstrated disparities in fine particulate matter (PM2.5) exposure, with Black people, among others, exposed to higher concentrations. We investigate the additional PM2.5 burden contributed by wildland fire smoke in the contiguous United States by race, ethnicity, urbanicity, per-capita income, and language spoken at home, using modeled total, non-fire, and fire PM2.5 from 2007 to 2018. Wildland fires contributed 7% to 14% of total PM2.5 annually, while non-fire PM2.5 declined 24%. Wildland fires cause greater PM2.5 exposure for Black and Native American people, and those who live in non-urban and low-income areas. Disparities in 2007 to 2018 average non-fire PM2.5 concentrations where Black people live (9.1 μg/m3) were further exacerbated by the contributions of fires (1.0 μg/m3). These results support efforts by public health agencies and air quality managers to reduce smoke exposure.

This method provides a calculation scheme applicable to Kerr black holes (for which case no analytic calculation of the late time tails has been presented so far). In this paper we develop the new technique and apply it to the case of massless scalar waves evolving on the background geometry of a static spherically-symmetric thin shell with a Schwarzschild exterior. The late time behavior of the scalar field at null infinity is calculated, and is explicitly related to the form of (quite arbitrary) initial data. This reproduces the well-known late time power-law decaying tails. In an accompanying paper we apply our approach to the complete Schwarzschild black hole geometry, where we obtain the familiar inverse-power late time tails at null infinity, as well as at time-like infinity and along the event horizon. A calculation of the late time power-law tails in the Kerr geometry, based on the same approach, will be presented in a forthcoming paper.

description: It is standard practice for covariates to enter a parametric model through a single distributional parameter of interest, for example, the scale parameter in many standard survival models. Indeed, the well-known proportional hazards model is of this kind. In this paper we discuss a more general approach whereby covariates enter the model through more than one distributional parameter simultaneously (e.g., scale and shape parameters). We refer to this practice as "multi-parameter regression" (MPR) modelling and explore its use in a survival analysis context. We find that multi-parameter regression leads to more flexible models which can offer greater insight into the underlying data generating process. To illustrate the concept, we consider the two-parameter Weibull model which leads to time-dependent hazard ratios, thus relaxing the typical proportional hazards assumption and motivating a new test of proportionality. A novel variable selection strategy is introduced for such multi-parameter regression models. It accounts for the correlation arising between the estimated regression coefficients in two or more linear predictors -- a feature which has not been considered by other authors in similar settings. The methods discussed have been implemented in the mpr package in R.

description: Casablanca, the economic capital of the country, is a city where several urban forms coexist. Casablanca has specificities compared to other cities in Morocco, but like many of them, this metropolis has varied urban forms that bear witness to the economic, social, and urban history of the city. These urban forms, including the old medieval core ‘Medina’, the city center, the new medina ‘Habous’ and the worker housing estates of colonial heritage, as well as the modern urban cores resulting from post-protectorate regulatory town planning, are the result of the successive transformations of the city. The city of Casablanca is currently experiencing an urban development marked by the emergence of major urban projects to international standards, which mark the transition from purely regulatory urban planning to operational town planning. These urban projects produce new urban forms that are part of a ‘dense and varied city’ approach. This approach advocates a typological diversity that is combined with a great diversity of urban and architectural quality. These new urban morphologies are new tools for urban planning, health-friendly urban planning, and climate change urban planning. This communication deals with the evolution of the urbanization modes of the city of Casablanca and highlights the different characteristics and contributions of these new urban forms experimented in Casablanca, through the case study of the urban renewal of Casa Anfa.

description: Abstract 

Background- Undernutrition and tuberculosis are the major concerns of underdeveloped regions of the world. Tuberculosis makes undernutrition worse and undernutrition weakens immunity, thereby increasing the likelihood that latent Tuberculosis will develop into active disease. Nevertheless little has been understood about undernutrition due to infectious disease including Tuberculosis in Ethiopia. This study aimed to fill this gap by studying the magnitude of undernutrition and associated factors among adult patients with TB in Jowhar public health facilities.

 

Objective: to assess the Magnitude of Undernutrition among tuberculosis patients in Jowhar TB hospital.

Methodology: Institutional-based retrospective study was conducted in Jowhar, from February 2023 to May the total sample size of the study was 50 The source populations were TB patients who have followed up for TB treatment at public health facilities of Jowhar. The sample size was allocated to the selected health facilities proportional to their size, and study subjects were enrolled to the study during the study period. Data were collected by a structured data sheet from the selected health center registration book. Data were entered into Data software and analyzed by using SPSS version 26. Descriptive statistical methods were used to summarize the socio demographic characteristics of the study participants

Result:

In this study, the magnitude of undernutrition was found to be 48 %.( 50 patients), 5(10%) of this have normal weight, 24(48%) have underweight and 21(420% have severe Undernutrition. Furthermore, 5(10%) had normal weight based on BMI classification.

 

Conclusion: The magnitude of undernutrition was found to be high. Age greater than forty five, living in rural area problem with eating and lack of nutritional care and support were the factors independently associated with undernutrition of TB patients. The nutritional derangement could call for fast nutritional intervention in the management of pulmonary tuberculosis patients.

description: Topologically non-trivial configurations of the hypermagnetic flux lines lead to the formation of hypermagnetic knots (HK) whose decay might seed the Baryon Asymmetry of the Universe (BAU).HK can be dynamically generated provided a topologically trivial (i.e. stochastic) distribution of flux lines is already present in the symmetric phase of the electroweak (EW) theory. In spite of the mechanism generating the HK, their typical size must exceed the diffusivity length scale. In the minimal standard model (MSM) (but not necessarily in its supersymmetric extension) HK are washed out. A classical hypermagnetic background in the symmetric phase of the EW theory can produce interesting amounts of gravitational radiation.

DEVELOPMENT OF A SKIN DOSING METHOD USING METHYL SALICYLATE
Creators: name: Bocklage, Clare
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2024

description: Assessments of military protective ensembles against vapor intrusion generally employ methyl salicylate, a sulfur mustard simulant. Currently, the MeS dose reaching the skin’s surface is estimated using passive sampling. The aim of this study was to develop a skin dosing method which can then be used to interpret biomonitoring data from full body exposures. A skin dosing method was developed that can be used in a future pilot study to quantify total skin dose. The method is comprised of a flow-through chamber placed over the exposure site, using a hydrophilic polyvinylidene fluoride material as the dosing vehicle. Air is drawn through the chamber and evaporated MeS captured on a sorbent tube. Extraction efficiency for the chosen vehicle was 98%, and 95% overall mass closure was achieved by combining the evaporated mass and extracted mass (vehicle and spacer). This demonstrates that absorbed dose can be quantified by subtraction. This method will aid in quantifying MeS dose during protective clothing testing.

description: Long-time behavior of spatial power-law correlation in one-dimensional self-gravitating system is numerically investigated. It is found that the power-law structure persists even after the system is virialized. The structure gradually disappears owing to energy exchange among particles. Energy distribution is quasi-stationary after the system is virialized.

description: This paper is concerned with the uniqueness in inverse acoustic scattering problems with the modulus of the far-field patterns co-produced by the obstacle (resp. medium) and the point sources. Based on the superposition of point sources as the incident waves, we overcome the difficulty of translation invariance induced by a single incident plane wave, and rigorously prove that the location and shape of the obstacle as well as its boundary condition or the refractive index can be uniquely determined by the modulus of far-field patterns. This work is different from our previous work on phaseless inverse scattering problems [2018 Inverse Problems 34, 085002], in which the reference ball technique and the superposition of incident waves were used, and the phaseless far-field data generated only by the the scatterer were considered. In this paper, the phaseless far-field data co-produced by the scatterer and the point sources are used, thus the configuration is practically more feasible. Moreover, since the reference ball is not needed, the justification of uniqueness is much more clear and concise.

Estimation of Occupational Exposure of Artisanal Fishers following the 2019 Oil Spill in Northeastern Brazil
Creators: name: Neal, Mercy Linden
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2024

description: The 2019 Oil Spill off the coast of Northeastern Brazil dramatically impacted the health, economy and environment of the coast of the state of Bahia. Artisanal fishing communities in the region were often interacted directly with the oil due both to the oil removal efforts that were led at the community level and due to their dependence on fishing to meet basic survival needs. Crude oil is a complex mixture of compounds including PAHs, VOCs, heavy metals, and hydrogen sulfide, which can lead to health effects including oxidative stress, heart disease, severe lower pulmonary disease, and severe neurological endpoints. Government response was conflicting and disjointed, increasing economic damage and health outcomes in these communities. These communities are primarily Afro-Indigenous, and the fishing moratorium following this spill exacerbated existing environmental inequity dramatically. This thesis estimated the exposures these communities experienced, building 6 epidemiological models from survey data taken from 6 communities in the year following the disaster. Epidemiological models created matched qualitative reports of exposure provided by community members, leading to the identification of potentially useful estimates of exposure using survey-centric data collection methods.
