description: We report the results of our observations of the S255IR area with the SMA at 1.3 mm in the very extended configuration and at 0.8 mm in the compact configuration as well as with the IRAM-30m at 0.8 mm. The best achieved angular resolution is about 0.4 arcsec. The dust continuum emission and several tens of molecular spectral lines are observed. The majority of the lines is detected only towards the S255IR-SMA1 clump, which represents a rotating structure (probably disk) around the young massive star. The achieved angular resolution is still insufficient for conclusions about Keplerian or non-Keplerian character of the rotation. The temperature of the molecular gas reaches 130-180 K. The size of the clump is about 500 AU. The clump is strongly fragmented as follows from the low beam filling factor. The mass of the hot gas is significantly lower than the mass of the central star. A strong DCN emission near the center of the hot core most probably indicates a presence of a relatively cold ($\lesssim 80$ K) and rather massive clump there. High velocity emission is observed in the CO line as well as in lines of high density tracers HCN, HCO+, CS and other molecules. The outflow morphology obtained from combination of the SMA and IRAM-30m data is significantly different from that derived from the SMA data alone. The CO emission detected with the SMA traces only one boundary of the outflow. The outflow is most probably driven by jet bow shocks created by episodic ejections from the center. We detected a dense high velocity clump associated apparently with one of the bow shocks. The outflow strongly affects the chemical composition of the surrounding medium.

Diffusion of a Passive Scalar Subject to Steady Flow in a Pipe
Creators: name: Burnett, Sarah
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2015

description: The Taylor Pipe Flow experiment was designed to be a continuation of the research
on the dispersion of soluble matter through a tube conducted by G.I. Taylor [10] [11].
In two-dimensional channel models and three-dimensional circular- and square-faced
model glass pipes, we explore the theory of Taylor dispersion explaining the motion of a
passive scalar transported by laminar flow. Studies here at the University of North Carolina
in Chapel Hill are implemented to better understand the stochastic system of the
dispersion, primarily by calculating the first three moments of the advection of the solute.
Depending on the characteristic length and mean velocity, we observe the effects
of Poiseuille flow as either advection or diffusion dominates at different regimes characterized
by the Taylor time scale, t = R2/D. We conduct experiments to better understand
the regimes characterized by the dimensionless Péclet number, Pe = UR/D, where R is
the pipe radius, U is the velocity, and D is the diffusion coefficient of the solute. In experiments,
we take the intensity of a fluorescein-dyed portion of distilled water and find
its corresponding concentration by solving an inverse problem of intensity to concentration.
This serves as results to compare with the theoretical approach.

description: Twelve years after the adoption of the Optional Protocol to the Convention against Torture and Other Cruel, Inhuman or Degrading Treatment or Punishment, the designated African National Preventive Mechanisms (NPMs) are struggling to achieve effectiveness in conducting monitoring visits to places of deprivation of liberty to preventing torture and ill-treatment. In a bid to understand what makes NPMs effective, this thesis employed a comparative study between two European and African NPMs, selected for their different organisational structure, and analysed how their structures, independence, powers, working methods, and cooperation with other international monitoring bodies and stakeholders influenced their effectiveness. The NPMs’ and the international monitoring bodies’ reports, NPM-related national legislation of the case studies, torture-related UN and regional conventions, and publications by the Subcommittee for the Prevention of Torture (SPT) and Committee for the Prevention of Torture (CAT) were analysed, and an interview conducted with the Slovene Deputy-Ombudsperson, who is also the head of the Slovene NPM. This thesis finds that, while there are many factors that make an NPM effective, they cannot be isolated from each other and the general working environment of the NPM. Therefore, just as national monitoring to prevent torture should adopt a holistic approach, implementing not only law but incorporating different measures suitable to the environment of the places of deprivation of liberty, a similar approach needs to be adopted to ensure NPMs effectiveness in Africa by looking at all factors relating to an NPM.

description: The Bigeye Chub (Hybopsis amblops) once inhabited streams and rivers in eastern and southeastern Illinois and was thought to be extirpated in the state by the 1970s. However, it was rediscovered in the 1990s from the Little Vermilion River. Today, H. amblops has become widespread and locally abundant in streams of the Wabash River drainage. Currently, little is known about the spawning and reproductive ecology of H. amblops. We conducted a study in the Salt Fork Vermilion River to determine the spawning schedule and microhabitats of H. amblops. Based upon near-weekly samples in May and June in 2019 and 2021, we determined H. amblops spawns in moderate water velocity over sandy gravel substrates when water temperatures are between 18–22 °C. Understanding such ecological traits is necessary for the continued success of H. amblops throughout its range.

description: We study the formation of Majorana states in quasi-1D and 2D square lattices with open boundary conditions, with general anisotropic Rashba coupling, in the presence of an applied Zeeman field and in the proximity of a superconductor. For systems in which the length of the system is very large (quasi-1D) we calculate analytically the exact topological invariant, and we find a rich phase diagram which is strongly dependent on the width of the system. We compare our results with previous results based on a few-band approximation. We also investigate numerically open 2D systems of finite length in both directions. We use the recently introduced generalized Majorana polarization, which can locally evaluate the Majorana character of a given state. We find that the formation of Majoranas depends strongly on the geometry of the system and if the length and the width are comparable no Majorana states can form, however, one can show the formation of "quasi-Majorana" states that have a local Majorana character, but no global Majorana symmetry.

description: This study aims to assess the physicochemical characteristics regulating the distribution and abundance of M. marcella larvae in six wetlands in the northern Colombia. Standardized techniques for collecting invertebrate and physicochemical data were used in 29 sampling points in an intraannual period. Mean pH and temperature oscillated in narrow ranges within wetlands (7.7 ± 0.09–8.6 ± 0.07; 28.1 ± 0.29–32.8 ± 0.17 °C, respectively), whereas ammonium concentrations and conductivity exhibited a wide variation (0.2 ± 0.03–2.8 ± 0.54 mg NH4 L−1; 861 ± 30.7–19254 ± 1706 µS cm−1, respectively). A total of 2586 individual M. marcella larvae were collected. Abundance was greater in wetlands influenced by the Magdalena River, with 19.4 ± 1.7 and 9.3 ± 1.4 individuals; followed by wetlands hydrologically influenced by seasonal runoff, with 8.1 ± 0.4 and 6.4 ± 0.4 individuals; and lowest in wetlands with influence of the Caribbean Sea, with 3.9 ± 0.3 and 0.3 ± 0.1 individuals. Abundances of M. marcella larvae exhibited similar variations at different months during the sampling period. Abundance and distribution of M. marcella larvae in wetlands of northern Colombia is strongly dependent on water conductivity, transparency and alkalinity. This study evidence that Odonata larvae are a valuable tool as bioindicators for wetland assessment and monitoring.
Adults in age, but not in wage : does the British sub-minimum wage for workers aged 18 to 21 amount to age discrimination under European law?

description: Second semester University: KU Leuven.
description: During the past several years, governments all over Europe have tried to promote integration of young workers into the labour market by diminishing their labour protection. At the same time, there has been an important evolution of European nondiscrimination law, particularly in relation to age discrimination. Yet no in-depth analysis has been carried out on what the limits of the justification of such reductions of labour rights are under European anti-age discrimination law. This leaves governments alone with prejudices and preconceived ideas when designing such measures. Thus the prime objective of this thesis is to shed some light on these limits. In order to do so, it utilises the case study of the British sub-minimum wage for workers aged 18 to 21, which is lower than the minimum wage for the general population. Furthermore, it analyses what the greatest problems may be when presenting a case of age discrimination of young workers before the European Court of Human Rights, the Court of Justice of the European Union and the European Committee of Social Rights. 9The thesis concludes that if European non-discrimination law is interpreted globally, a subminimum wage that does not take into consideration any other individual characteristic besides age, is disproportionate to the aim sought and thus amounts to age

description: We study transport properties for a quantum dot coupled to normal leads with a pseudogap density of states at zero temperature, using the second-order perturbation theory based on the Keldysh formalism. We clarify that the hybridization function $Γ(ω)\propto |ω|^r\; (0 \le r < 1) $ induces the cusp or dip structure in the density of states in the dot when finite bias voltage is applied to the interacting quantum dot system. It is found that the current-voltage characteristics and differential conductance are drastically changed at $r=1/2$.

description: We explore the performance of a statistical learning technique based on Gaussian Process (GP) regression as an efficient non-parametric method for constructing multi-dimensional potential energy surfaces (PES) for polyatomic molecules. Using an example of the molecule N$_4$, we show that a realistic GP model of the six-dimensional PES can be constructed with only 240 potential energy points. We construct a series of the GP models and illustrate the convergence of the accuracy of the resulting surfaces as a function of the number of ${\it ab \ initio}$ points. We show that the GP model based on $\sim 1500$ potential energy points achieves the same level of accuracy as the conventional regression fits based on 16,421 points. The GP model of the PES requires no fitting of ${\it ab \ initio}$ data with analytical functions and can be readily extended to surfaces of higher dimensions.

Perspectives of Wife-Husband Pairs on Their Roles in Infant and Young Child Feeding Decision-Making in the Context of Malawi's Prevention of Mother-to-Child HIV Transmission Program

description: Studies have examined the role of male involvement in HIV counseling and testing
within prevention of mother-to-child transmission (PMTCT) programs, but there is no
corresponding data on male involvement in infant and young child feeding (IYCF)
decision-making within the context of HIV. We explored wives’ and husbands’
perceptions of their roles in feeding decision-making and practice in the context of
Malawi’s Option B+ PMTCT program through in-depth interviews conducted in the
catchment areas of 2 urban and 2 rural government clinics in Lilongwe District.
Participants were 15 wife-husband pairs (interviewed separately), where the wife was ≥
18 years, HIV-positive, and had a child < 24 months. The interviews were analyzed using
thematic content analysis. Husbands were generally less well informed about IYCF
recommendations than their wives, who were advised on IYCF during antenatal and
PMTCT clinic visits. Husbands were unable to accompany their wives to clinic
appointments and usually deferred to their wives in IYCF decision-making. Wives were
responsible for caring for children, including breastfeeding and feeding complementary
foods. Husbands provided monetary support for purchasing food and offered verbal
support to encourage their wives to continue with recommended IYCF practices. Many
husbands found it difficult to support adequate complementary feeding due to household
food insecurity. In conclusion, Malawian husbands and wives reported highly gendered
roles in relation to IYCF decision-making and practice in the context of HIV, but women
were interested in having more involvement in IYCF by their husbands. To address this
gap, strategies should be tested for getting messages on IYCF to husbands through male-friendly
radio and community-based programs or by encouraging them to participate in
PMTCT visits with their wives.

description: Mobile learning (mLearning) is the cutting-edge learning platform to really gain traction, driven mostly by the huge uptake in smartphones and their ever increasing uses within the educational society. Education has long benefitted from the proliferation of technology; however, mLearning adoption has not proceeded at the pace one might expect. There is a disconnect between the rate of adoption of the underlying platform (smartphones) and the use of that technology within learning. The reasons behind this have been the subject of several research studies. However, previous studies have mostly focused on investigating the critical success factors (CSFs) from the student perspectives. In this research, we have carried out an extensive study of the six factors that impact the success of mLearning from instructors perspectives. The results of the research showed that three factors: technical competence of instructors, Instructors autonomy, and blended learning are the most important elements that contribute to mLearning adoption from instructors perspectives.

Analysis of Weight Loss Attitudes and Behaviors of Metabolically Healthy and Unhealthy Adults in the United States, 2009-2014
Creators: name: Ranganna, Adesh
Publisher: name: The University of North Carolina at Chapel Hill University Libraries

description: BackgroundRecent evidence suggests that moderate diet-induced weight loss reduces cardiometabolic risk in individuals who are "metabolically unhealthy normal weight" (MUH-NW). However, while weight management in people with obesity is well-studied, the relevant attitudes and behaviors in lean people are unknown. The lack of information about weight loss perceptions in the MUH-NW prompted an investigation into the factors that influence weight management practices in metabolically healthy and unhealthy American adults.MethodsPopulation-based cross-sectional analysis of American adults (n=6,218; weighted n=195.7 million; age≥20) using pooled data from the 2009-2014 National Health and Nutrition Examination Surveys. The explanatory variables of interest were metabolic health, perceived weight status, and measured weight status. The outcomes of interest were weight perception, weight loss intent and successful weight loss. Logistic regression models were adjusted for known confounders including age, race/ethnicity, sex, and income-to-poverty ratio. ResultsIn adjusted models, adults who were metabolically unhealthy had 1.404 (1.167-1.689) the odds of intending to lose weight and 1.043 (0.876-1.242) the odds of successfully losing weight compared with metabolically healthy adults. Adults who perceived themselves as overweight had 6.124 (5.229- 7.172) the odds of intending to lose weight when compared to adults who perceived themselves as normal weight, and adults who measured as overweight had 3.920 (3.173-4.843) the odds of intending to lose weight when compared to adults who measured as normal weight. ConclusionsMetabolic health can influence individuals’ weight management behaviors. Weight perceptions may play a greater role than measured weight in shaping weight loss intention.

description: We investigate a possibility to generate non-classical states in light-matter coupled noisy quantum systems, namely the anisotropic Rabi and Dicke models. In these hybrid quantum systems a competing influence of coherent internal dynamics and environment induced dissipation drives the system into non-equilibrium steady states (NESSs). Explicitly, for the anisotropic Rabi model the steady state is given by an incoherent mixture of two states of opposite parities, but as each parity state displays light-matter entanglement we also find that the full state is entangled. Furthermore, as a natural extension of the anisotropic Rabi model to an infinite spin subsystem, we next explored the NESS of the anisotropic Dicke model. The NESS of this linearized Dicke model is also an inseparable state of light and matter. With an aim to enrich the dynamics beyond the sustainable entanglement found for the NESS of these hybrid quantum systems, we also propose to combine an all-optical feedback strategy for quantum state protection and for establishing quantum control in these systems. Our present work further elucidates the relevance of such hybrid open quantum systems for potential applications in quantum architectures.

description: The endangered Chinese giant salamander (Andrias davidianus) is an endangered species among the conserved Chinese amphibians. Tourism-related pressures have increased for this species recently. The effect of tourism on the hatching rate of the target species was determined by experimentally observing the influences of different intensities of tourism disturbance on salamander in the Zhangjiajie Chinese Giant Salamander National Nature Reserve. Water quality factors (e.g. total nitrogen, total phosphorus, dissolved oxygen and Escherichia coli abundance) were analysed, and hatching rate was estimated. Results showed that high levels of tourism disturbance (500,000–1,200,000 visitors per year) had active effects on the hatching time and negative effects on the hatching rate. The prediction performance of artificial neural network models was validated by the low root mean square error values of 2.2539 and 3.2612 for the training and testing data and high determination coefficient values of 0.9732 and 0.9508 for the training and testing data, respectively. The potential for positive or negative feedback mechanisms in such relationships between tourists and wildlife highlights the importance of considering both sides of the complex interaction to find a balance between the development of tourism and wild animal protection. High tourism disturbance deteriorated the water quality. Artificial neural network model was successfully used in predicting the hatching rate. A mutual relationship was observed between salamander and tourists.

description: With advances in technology over the past few decades the characteristics of an infant considered to be at the margin of viability has changed markedly. Medical interventions are now able to help sustain the life of infants born at gestational ages as young as 23 weeks and at higher acuity levels than previously seen. The birth of infants at the margin of viability has raised serious ethical questions regarding survival, parenting, and suffering. These questions challenge the way in which we view the interactions between the family and the providers in making decisions surrounding the infant’s care. Each party, the family and the providers, share concern in promoting the best interest of the infant. However, with differences in expertise, experience, and guiding ethical frameworks the two parties have the potential to hold contrasting views on the care of the infant. Further research on the process of regoaling and the incorporation of the collaborative communication model in provider education may benefit future conversations and family-provider interactions in cases of birth at the margin of viability.

Effects of Discourse Status and Planning Difficulty on Acoustic Variation
Creators: name: Keung, Lap-Ching
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2013

description: Repeated words within a discourse tend to be acoustically reduced, i.e., shorter in duration. This variation can be explained by a pragmatic selection rule (discourse status) or by speaker facilitation (planning difficulty). The main question of interest: Are these effects part of the same cognitive system or different systems? During the experiment, speakers saw an array of four objects and described a sequence of two movements like in (1).
(1) The chiddle moved above the hamel.
The cammer moved above the neeken.
The target’s discourse status (new vs. given) and planning difficulty (novel vs. familiar) were manipulated. For novel targets, the combination of abstract drawings plus nonword labels made planning more difficult. At the onset latency, determiner, and target noun, there were main effects of discourse status and planning difficulty. Durations were longer for new vs. given and novel vs. familiar. These results replicated findings from previous research. More importantly, at the target noun, there was a trend towards an interaction between discourse status and planning difficulty. Givenness had a greater effect on novel targets. Although not significant, onset latency patterned in the same way as target duration, showing a correlation between the two factors. These results together suggest that discourse status is partially mediated by planning difficulty, which further suggests that the two effects are operating from the same cognitive system.
A missense mutation in the acnB gene indirectly affects the growth, metabolism and biological fitness in a spontaneous compensatory mutant of antibiotic-resistant Neisseria gonorrhoeae

description: Neisseria gonorrhoeae, the causative agent of the sexually transmitted infection
gonorrhea, has developed resistance to every antimicrobial used against it. Ceftriaxone-resistant N. gonorrhoeae strains harbor mosaic penA alleles that encode highly mutated forms of Penicillin-Binding Protein 2 (PBP2), the lethal target of ceftriaxone. When bacteria develop resistance to antibiotics through an extensive alteration of an essential protein, they often incur a fitness cost. To have success as a pathogen, they must overcome this fitness deficit. We have hypothesized that antibiotic-resistant clinical isolates acquire compensatory mutations to help alleviate the fitness cost associated with resistance. Wild-type strains harboring a mosaic penA allele have reduced fitness both in vitro and in vivo, but compensatory mutants with increased
biological fitness were isolated. In one such strain, a mutation (G348D) in acnB, which encodes the tricarboxylic acid (TCA) cycle aconitase, was identified. The hallmark of this compensatory mutant is that it grows rapidly during log-phase growth, but then plateaus early as it enters into stationary phase growth. The acnB-G348D mutation is both necessary and sufficient to impart the growth phenotype characteristic of compensatory mutant. Western blots of AcnB during the growth cycle show that wild-type AcnB increases in abundance as the cells enter stationary phase, whereas in the AcnB mutant, expression decreases by 2- to 3- fold. Interestingly, acnB mRNA levels do not account for changes in AcnB protein levels. These data suggest that acnBG348D acts as a functional knockout in regards to the role of AcnB in the TCA cycle. Any fitness benefits associated with this mutation do not appear to be directly associated with the activity of AcnB in the TCA cycle.

description: Freshwater ecosystems are facing degradation from human activities in the form of alterations of flow regimes, changes in land-use, and intensive water abstraction, in turn generating adverse effects on biodiversity and ecological functionality. Efficient assessment of river/stream ecosystem response to such anthropogenic changes is urgently needed. Many human activities that have an effect on water quality and river health are increasing along the Mohlapitsi River, which used to be one of the rivers with good water quality in South Africa. The aim of the study was to assess spatial variation in macroinvertebrate assemblages in relation to water quality of the Mohlapitsi River. A combination of canonical correspondence analysis and univariate analyses were used to examine the macroinvertebrate assemblages at six different sites of the Mohlapitsi River. The spatial difference in macroinvertebrate abundance was mostly related to changes in water quality. The number of taxa and the diversity of macroinvertebrates remained relatively high across the river as compared to other rivers in the Olifants River System. The midstream and downstream sites were mostly dominated by macroinvertebrates tolerant to disturbance/pollution. The most abundant family was the Thiaridae (about 60%) and mainly occurred in the midstream and downstream sites of the river (more disturbed sites). The study showed a higher evenness index in the upstream than the midstream and downstream sites which is an indication of good water quality at the upstream sites of the river. The results suggest that the river is being subjected to a moderate environmental pollution, which requires continuous assessment and monitoring to determine causes and initiate remedial measures.

description: River water degradation arising from wastewater effluents is a major factor contributing to the deterioration of river ecosystems; yet direct evidence of the beneficial influence of long-term sewerage development on such ecosystems is scarce at a basin scale. The present study, over 12 years, examined changes in sewerage connection rate, water quality, and invertebrate assemblages at 10 study sites in the Shigenobu River, southwestern Japan, and investigated the relationships between them. Sewerage connection rates increased in the three main municipalities in the basin during the study period (range: 8.6%–31.4%). At the lowland sites, the concentration of total inorganic nitrogen (TIN) decreased by 38.9% on average and the richness metrics of invertebrate assemblages significantly increased at several sites. Furthermore, the richness metrics negatively related with TIN concentration, implying that invertebrate diversity recovery was the result of water quality improvement. Our findings strongly suggest that sewerage system improvement is an effective measure for restoring river ecosystems.
Migraine Self-Management: Pathways to Learning
Creators: name: Matthews, Anna
Publisher: name: The University of North Carolina at Chapel Hill University Libraries

description: Background: Self-management is the cornerstone of migraine management. How women learn to self-manage is largely unexplored. Women in lower social locations (i.e., those with lower income and education) are disproportionately affected by migraine severity and disability. Objective: To explore pathways to learning self-management of migraine in women. Methods: Part of a parent study on migraine self-management, this exploratory portion of the study used semi-structured interviews to gain insight into perceptions of how women with migraine learn to self-manage their condition. Grounded theory and content analysis were used to analyze qualitative interview data in QSR International’s NVivo 11 Pro Software (2017). Results: Women model self-management strategies as well as agency in relationship to migraine that they saw trusted family members (i.e., trusted migraineurs) use early in life. These learned behaviors and attitudes may contribute to the disparity in burden of migraine among women of lower social location. It is necessary for nursing to consider the generational and familial context in which women learn to self-manage migraine.

Functional Actuation of Mandrel Formed Twisted Coiled Polymer (TCP) Muscles in Organic Temperature Ranges
Creators: name: Witham, Nicholas
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2018

description: Mandrel formed TCP muscles are an existing, but under researched form of thermally actuated artificial muscles, which are made by coiling a highly twisted monofilament plastics such as Nylon 6/6 (sewing thread) helically. An increase in temperature causes the fiber to shrink axially and expand radially. The radial expansion causes fiber untwisting, which compounds in a much larger tensile actuation (TA) and tensile stress (TS). To cause expansions, TCP muscles can also be coiled in the opposite direction of their fiber twist. These heterochiral fibers can be used to counteract length changes of the homochiral muscles caused by ambient temperature changes. Currently, the maximum contraction of 49% for mandrel formed TCP muscles has taken place at a 5.1 spring index and has achieved a 1 MPa stress over a 70K temperature range (25°C to 95°C). Human muscle have an average TS of 0.35 MPa and TA greater than 40%. To make viable TCP muscles to be comparable with human muscle, which have an average TS of 0.35 MPa and TA greater than 40% that actuate over body temperature range of (33.2 °C to 38.2 °C) the contraction must be improved by 1143% and the stress can be reduced by 65%. The main goal of this study was to conduct an isometric test where the muscles are heated from 33.2 °C to 38.2 °C and contract while tensioned by a 1.75g (most likely 2g) weight to determine if the muscle made from 0.25mm diameter monofilament can contract 40% its length while exerting a stress of 0.35 MPa.
