description: The chemical composition of a star's atmosphere reflects the chemical composition of its birth environment. Therefore, it should be feasible to recognize stars born together that have scattered throughout the galaxy, solely based on their chemistry. This concept, known as "strong chemical tagging", is a major objective of spectroscopic studies, but has yet to yield the anticipated results. We assess the existence and the robustness of the relation between chemical abundances and birth place using known member stars of open clusters. We followed a supervised machine learning approach, using chemical abundances obtained from APOGEE DR17, observed open clusters as labels and different data preprocessing techniques. We found that open clusters can be recovered with any classifier and on data whose features are not carefully selected. In the sample with no field stars, we obtain an average accuracy of $75.2\%$ and we find that the prediction accuracy depends mostly on the uncertainties of the chemical abundances. When field stars outnumber the cluster members, the performance degrades. Our results show the difficulty of recovering birth clusters using chemistry alone, even in a supervised scenario. This clearly challenges the feasibility of strong chemical tagging. Nevertheless, including information about ages could potentially enhance the possibility of recovering birth clusters.

Compatible tours for the asymmetric traveling salesman problem

Subjects: subject: Computer Science.

description: In this thesis, we consider this question through the study of a problem called the Compatible Tour Problem (CTP). Given an optimal ASEP solution x*, a compatible tour for x* is a directed Hamiltonian cycle that has exactly one edge coming in and one edge going out of the node set (henceforth called a tight set) of every tight cut of value 2 of x*. The compatible tour problem is the problem of finding a minimum cost compatible tour for x*, where x* is the optimal solution of the ASEP. Note that it is suspected that CTP is an NP-hard problem. We consider the problem of finding a minimum cost "almost" compatible tour for a given solution x* for ASEP. The "almost" compatible tour satisfies important tight sets in x* which are nested with respect to each other. We then develop a heuristic to find this tour as a heuristic solution to the ATSP which is based on the well-known cheapest insertion heuristic for the symmetric travelling salesman problem. Finally, we test this heuristic and give the results. (Abstract shortened by UMI.)

description: We present an analysis of a deep (1σ = 13 μJy) cosmological 1.2 mm continuum map based on ASPECS, the ALMA Spectroscopic Survey in the Hubble Ultra Deep Field. In the 1 arcmin2 covered by ASPECS we detect nine sources at significance at 1.2 mm. Our ALMA-selected sample has a median redshift of z = 1.6 ± 0.4, with only one galaxy detected at z > 2 within the survey area. This value is significantly lower than that found in millimeter samples selected at a higher flux density cutoff and similar frequencies. Most galaxies have specific star formation rates (SFRs) similar to that of main-sequence galaxies at the same epoch, and we find median values of stellar mass and SFRs of 4.0 × 1010 M⊙ and ∼40 M⊙yr-1, respectively. Using the dust emission as a tracer for the interstellar medium (ISM) mass, we derive depletion times that are typically longer than 300 Myr, and we find molecular gas fractions ranging from ∼0.1 to 1.0. As noted by previous studies, these values are lower than those using CO-based ISM estimates by a factor of ∼2. The 1 mm number counts (corrected for fidelity and completeness) are in agreement with previous studies that were typically restricted to brighter sources. With our individual detections only, we recover 55% ±4% of the extragalactic background light (EBL) at 1.2 mm measured by the Planck satellite, and we recover 80% ±7% of this EBL if we include the bright end of the number counts and additional detections from stacking. The stacked contribution is dominated by galaxies at z ∼ 1-2, with stellar masses of (1-3) ×1010 M⊙. For the first time, we are able to characterize the population of galaxies that dominate the EBL at 1.2 mm.

description: In this paper we use ASPECS, the ALMA Spectroscopic Survey in the Hubble Ultra Deep Field in band 3 and band 6, to place blind constraints on the CO luminosity function and the evolution of the cosmic molecular gas density as a function of redshift up to z ∼ 4.5. This study is based on galaxies that have been selected solely through their CO emission and not through any other property. In all of the redshift bins the ASPECS measurements reach the predicted 'knee' of the CO luminosity function (around 5 ×109 K km s-1 pc2). We find clear evidence of an evolution in the CO luminosity function with respect to z∼0, with more CO-luminous galaxies present at z∼2. The observed galaxies at z∼2 also appear more gas-rich than predicted by recent semi-analytical models. The comoving cosmic molecular gas density within galaxies as a function of redshift shows a drop by a factor of 3-10 from z∼2 to z∼0 (with significant error bars) and possibly a decline at z > 3.
Single-cell and hierarchical wireless data broadcast systems: Modeling, performance analysis, and optimal scheduling

Subjects: subject: Engineering, Electronics and Electrical.

description: Wireless Data Broadcast (WDB) is known as a highly efficient information delivery mechanism of nearly unlimited scalability. Over the last few years, due to the appealing properties and a wide area of possible application, a large number of new solutions and ideas related to WDB have been proposed. However, most of those solutions employ overly simplified assumptions concerning the system operation and user behaviour, and therefore fail to provide a broader insight into the nature and performance of WDB as found in the real world. The work presented in this thesis aims to overcome the main limitations of the previous published research works on WDB. In particular, the following contributions are made. (1) We propose a new model of TDM-based single-cell WDB systems, which extends over both broadcast and unicast data retrieval principles, and assumes realistic-impatient user behaviour patterns. Based on this model, we define and derive exact mathematical expressions for several performance measures that seem most appropriate for the analysis of WDB systems. Consequently, we prove that there exists a single broadcast scheduling scheme (Soptimal), which can ensure the optimal system performance with respect to all of the measures at once, as well as the system's throughput, QoS and GoS. (2) The actual search for Soptimal, both in WDB systems of uniform and variable user mobilities, turns out to be a complex non-linear double inequality-constrained optimization problem, without a tractable closed-form solution. However, by exploiting some mathematical properties of the main cost function, we prove that the given optimization problem can be considerably simplified. Based on this simplification, we derive a closed form approximate expression for Soptimal and, consequently, we propose an algorithm for fast, CPU conserving estimation of Soptimal . Experimental results verify that the proposed algorithm requires minimum computation, while providing performance almost identical to Soptimal obtained through numerical estimation. (3) For the completeness of our discussion on single-cell WDB systems, we also consider the possibility of frequency-division-multiplexing (FDM) WDB. We prove that for any given FDM-based broadcast schedule there exists a TDM-based broadcast schedule that results in a better overall system performance. With this proof, we ultimately justify our initial decision to make TDM-WDB the main focus of this work. (Abstract shortened by UMI.)
Enriching knowledge: A collaborative approach between sport coaches and a consultantfacilitator

description: The purpose of this research project was to explore how knowledge can be enriched when a sport pedagogy and psychology consultant/facilitator collaborated with sport coaches to help them learn through their everyday coaching experiences. A collaborative inquiry approach was used. As the initiating researcher, I acted as a consultant/facilitator, working with coaches of two sports, athletics and alpine skiing. Data were mostly generated using interviews (semi-structured and on-going informal), participant observation, my journal, and, in Study Two, group meetings. In Study One, I made myself available as a consultant to six coaches from one athletics club, if they wanted to share any coaching issues with me. For six months I visited the coaches while they worked. The coaches mostly shared issues relating to sport psychology. Interactions among these coaches were mostly one-on-one, with little sharing of coaching issues between themselves. My work with them was of the same individual nature. The first two parts of Study Two involved two contexts in which I acted as a facilitator with groups of ski coaches (Part One, seven coaches and Part Two, six coaches). My role was to nourish knowledge creation within the coaches' community of practice (CoP). A series of round table meetings were the site for much of the negotiation of meaning that was the result of coaches sharing knowledge about coaching issues. The coaches found they learned a lot, that communication between them was improved, they enjoyed the process, and that their athletes benefited from all of this. In Part Three of this study, I stepped back and observed what happened to the CoPs without a facilitator. Two groups were involved in this study. One group was partially successful but found it difficult to keep up the learning in the CoP without a person responsible for coordinating the process. The other group had leadership problems and never met with the purpose of learning through negotiation of issues relating to their practice. Knowledge sharing in this group was mostly one-on-one. Recommendations are made concerning coach education, especially in relation to how this approach to learning through participation can compliment existing formal education.

Cation distribution in the europium iron garnet series Eu3Fe5-xA1xO12.

Subjects: subject: Physics, Condensed Matter.

description: The cation distributions in europium iron garnet Eu3Fe5 5-xAlxO12 series have not been determined yet since they were synthesized and studied by Yamaguchi and Sakuraba twenty years ago. In this thesis, the Fe-Al distributions over the octahedral ( a) and tetrahedral (d) sites in the europium iron garnet Eu3Fe5-xAlxO12 series have been determined by powder X-ray diffraction (XRD) and 57Fe Mossbauer spectroscopy (57Fe MS). The 57Fe MS spectra are collected at temperatures above the Neel temperatures of the studied samples and the cation distributions are derived from both the raw and thickness-corrected MS spectra. It is found that Al atoms occupy both the a and d sites. Higher Al concentration in the d sites is interpreted as the evidence that Al atoms enter preferentially the d sites due to the smaller size of Al ions compared with Fe ions. MS gives more reliable results of the Fe-Al distributions than XRD, which could be ascribed to the sensitivity of MS to the local environment around the iron nucleus at the specific site.

description: Despite recent progress, the question of what regulates the star formation efficiency in galaxies remains one of the most debated problems in astrophysics. According to the dominant picture, star formation (SF) is regulated by turbulence and feedback, and the SFE is 1-2% per local free-fall time. In an alternate scenario, the SF rate in galactic disks is linearly proportional to the mass of dense gas above a critical density threshold. We aim to discriminate between these two pictures thanks to high-resolution observations tracing dense gas and young stellar objects (YSOs) for a comprehensive sample of 49 nearby massive SF complexes out to d < 3 kpc in the Galactic disk. We use data from CAFFEINE, a 350/450 $μ$m survey with APEX/ArTéMiS of the densest portions of all southern molecular clouds, in combination with Herschel data to produce column density maps at 8" resolution. Our maps are free of saturation and resolve the structure of dense gas and the typical 0.1 pc width of molecular filaments at 3 kpc, which is impossible with Herschel data alone. Coupled with SFR estimates derived from Spitzer observations of the YSO content of the same clouds, this allows us to study the dependence of the SFE with density in the CAFFEINE clouds. We also combine our findings with existing SFE measurements in nearby clouds to extend our analysis down to lower column densities. Our results suggest that the SFE does not increase with density above the critical threshold and support a scenario in which the SFE in dense gas is approximately constant. However, the SFE measurements traced by Class I YSOs in nearby clouds are more inconclusive, since they are consistent with both the presence of a density threshold and a dependence on density above the threshold. Overall, we suggest that the SFE in dense gas is primarily governed by the physics of filament fragmentation into protostellar cores.

description: Preclinical studies show that blocking Interleukin–1 (IL–1) retards the progression of Amyotrophic Lateral Sclerosis (ALS). We assessed the safety of Anakinra (ANA), an IL–1 receptor antagonist, in ALS patients. In a single arm pilot study we treated 17 ALS patients with ANA (100 mg) daily for one year. We selected patients with dominant or exclusive lower motor neuron degeneration (LMND) presentation, as peripheral nerves may be more accessible to the drug. Our primary endpoint was safety and tolerability. Secondary endpoints included measuring disease progression with the revised ALS functional rating scale (ALSFRSr). We also quantified serum inflammatory markers. For comparison, we generated a historical cohort of 47 patients that fit the criteria for enrolment, disease characteristics and rate of progression of the study group. Only mild adverse events occurred in ALS patients treated with ANA. Notably, we observed lower levels of cytokines and the inflammatory marker fibrinogen during the first 24 weeks of treatment. Despite of this, we could not detect a significant reduction in disease progression during the same period in patients treated with ANA compared to controls as measured by the ALSFRSr. In the second part of the treatment period we observed an increase in serum inflammatory markers. Sixteen out of the 17 patients (94%) developed antibodies against ANA. This study showed that blocking IL–1 is safe in patients with ALS. Further trials should test whether targeting IL–1 more efficiently can help treating this devastating disease.
Synthèse d'allocolchicinoides via une arylation directe

description: Le motif biaryle tricyclique est un motif important en chimie médicinale et est présent dans une grande variété de produits naturels. Les chimistes ont développé au cours des années différentes méthodologies pour les synthétiser. La majorité des réactions impliquent l'utilisation d'un aryle fonctionnalisé par un organometallique et réagissant avec un halogénure d'aryle. Récemment, notre laboratoire rapportait une nouvelle procédure permettant de synthétiser des biaryles tricycliques d'une façon efficace et rapide. Cette nouvelle méthodologie est une réaction d'arylation directe catalysée par le palladium, par laquelle la partie organometallique a été remplacée par un hydrogène. Ainsi, un halogénure d'aryle peut maintenant réagir avec un aryle simple pour former le biaryle désiré. Cette réaction d'arylation directe a été récemment étendue à la formation de biaryles tricycliques contenant un cycle à sept membres. Elle peut s'effectuer à partir des chlorures ou des bromures d'aryles. Cette méthodologie a donc été employée dans la synthèse formelle de l'allocolchicine et d'un de ses analogues. Pour effectuer la réaction d'arylation directe d'une façon efficace, il a été détermine que la proportion ligand/palladium jouait un rôle primordial dans la quantité de produit hydrodéhalogène obtenue. De plus, le choix du ligand, par ses propriétés stériques et électroniques, a un impact sur le pourcentage de conversion obtenu lors de la cyclisation. Les ligands riches en électrons, tels que 2-(dicyclohexylphosphino)-2'- N,N-dimethylaminobiphenyle, sont les ligands qui ont fourni les meilleurs résultats. Par ailleurs, concernant la formation du centre chiral retrouvé dans l'allocolchicine, deux stratégies de synthèse ont été explorées, soit un couplage asymétrique direct et une réduction enantiosélective. Finalement, l'alcool chiral a été obtenu à l'aide d'une réduction enantiosélective d'une cétone via un réactif de bore, dérivé d'un mélange équimolaire de pinène et de 9-BBN.
Cultural identity and branding: Insights from a multiple identities perspective in a globalised world

description: This thesis aims to better understand the influence of ethnic, national, and global cultural identities on ethnic, national and global brand behaviours from single and multiple cultural identities perspectives. The findings support assertions that consumers' cultural identities influence their brand behaviours, depending on the level of their identification with the cultural identities and the amalgamation of these identities. The findings also established the existence of anchoring cultural identity in multiple identities conditions. These key findings have implications for studying multiple cultural identities and brands' target markets.
title: “A Question of Value?” Mapping and measuring the Scottish music industries
Creators: name: Allan, Robert
Publisher: name: University of Glasgow
Year: 2024

description: The Scottish music industries have so far been neglected in favour of mapping UK-wide music activities. Although small in scale, Scotland often punches above its weight in creative output and deserves to be examined on its own merit. Therefore, this study will redirect the academic focus to the Scottish context, offering the first national mapping investigation of the last twenty years. 

The thesis is a sociological investigation exploring the working lives and experiences of music creators and cultural intermediaries living in Scotland. The thesis uses semi-structured interviews and an online survey with the additional collection of desk-based research. The study first provides a foundation for the remainder of the thesis by examining seven key sectors of activity from an artistcentric perspective. Those sectors are then measured to estimate their economic worth. The music sector is then examined for its value-creating abilities, arguing that exchange-value should not be given primacy over use-value. Finally, the thesis examines the impact of Covid-19 in Scotland, arguing that several structural flaws, identifiable pre-pandemic, were only exacerbated by lockdown measures.

description: We present a search for [C ii] line and dust continuum emission from optical dropout galaxies at z > 6 using ASPECS, our Atacama Large Millimeter submillimeter Array Spectroscopic Survey in the Hubble Ultra-deep Field (UDF). Our observations, which cover the frequency range of 212-272 GHz, encompass approximately the range of 6 < z < 8 for [C ii] line emission and reach a limiting luminosity of L [C ii] ∼ (1.6-2.5) ×108 L o. We identify 14 [C ii] line emitting candidates in this redshift range with significances >4.5σ, two of which correspond to blind detections with no optical counterparts. At this significance level, our statistical analysis shows that about 60% of our candidates are expected to be spurious. For one of our blindly selected [C ii] line candidates, we tentatively detect the CO(6-5) line in our parallel 3 mm line scan. None of the line candidates are individually detected in the 1.2 mm continuum. A stack of all [C ii] candidates results in a tentative detection with S 1.2 mm = 14 ±5 μJy. This implies a dust-obscured star-formation rate (SFR) of (3 ± 1) M o yr-1. We find that the two highest-SFR objects have candidate [C ii] lines with luminosities that are consistent with the low-redshift L [C ii] versus SFR relation. The other candidates have significantly higher [C ii] luminosities than expected from their UV-based SFR. At the current sensitivity, it is unclear whether the majority of these sources are intrinsically bright [C ii] emitters, or spurious sources. If only one of our line candidates was real (a scenario greatly favored by our statistical analysis), we find a source density for [C ii] emitters at 6 < z < 8 that is significantly higher than predicted by current models and some extrapolations from galaxies in the local universe.

description: The German Environmental Survey (GerES) is a population-representative, cross-sectional study on environ-mental exposures of the general population of Germany. GerES has repeatedly been conducted since 1985 by the German Environment Agency (UBA) in close collaboration with the Health Interview and Examination Surveys of the Robert Koch Institute (RKI). In the German Environmental Survey for Children and adolescents 2014-2017 (GerES V) pollutants and other environmental stressors were measured in human samples as well as in the homes of 3- to 17-year-old children and adolescents. Interviews were conducted about health-related behaviors and living conditions. The GerES V basic program encompassed examinations of whole blood, blood plasma, morning urine and drinking water samples, measurements of ultrafine particles and noise levels, comprehensive stan-dardized interviews, and self-administrated questionnaires. Additional modules on volatile organic compounds and aldehydes, particulate matter (PM2.5) in indoor air, organic compounds in drinking water and pollutants in house dust were conducted in subsamples. Potential GerES V participants were identified and attained by the RKI from those participants who were examined and interviewed for the cross-sectional component of the second follow-up to the German Health Interview and Examination Survey for Children and Adolescents (KiGGS Wave 2). The gross sample of GerES V comprised 3031 children and adolescents of which 2294 finally took part in the survey. This equals a total response rate of 75.7 %. Response rates varied, depending on region, type of mu-nicipality, age and sex, from 66.0 % to 78.3 %. By calculating individual case weights, discrepancies due to sample design and non-response between the GerES V sample and the whole population could be considered in statistical analysis. Therefore, the representativeness of the GerES V results with regard to age, sex, community size and region was assured. © 2021 Elsevier GmbH.
Quantitative capacitance measurements using a scanning probe microscope

Subjects: subject: Engineering, Electronics and Electrical.

description: This thesis describes the theory, simulation and experimental implementation of a method by which an atomic force microscope with scanning capacitance microscopy (SCM) capability can be employed in a nontraditional fashion to quantitatively measure the capacitance of metal-oxide-semiconductor (MOS) structures. The capability to deduce sample capacitances is based on resonant frequency shifting, which relies on the SCM's ultra-precise capacitance sensor. The technique, however, is distinct from scanning capacitance microscopy imaging, with the MOS capacitor an integral part of the system resonant circuit. SPICE simulations are performed to extract phenomenological resonant circuit parameters specific to the instrumentation, subsequently permitting sample capacitance to be quantitatively extracted from the system response. Our technique represents a novel application of SCM instrumentation and has important applications in the analysis of on-chip passive components for future technology generations. Initial experimental results are promising, suggesting the extension of the technique to advanced technology nodes.

description: Context. Airless planetary objects have their surfaces covered by craters, and these can be used to study the characteristics of asteroid populations. Planetary surfaces present binary craters that are associated with the synchronous impact of binary asteroids. Aims. We identify binary craters on asteroids (1) Ceres and (4) Vesta, and aim to characterize the properties (size ratio and orbital plane) of the binary asteroids that might have formed them. Methods. We used global crater databases developed in previous studies and mosaics of images from the NASA DAWN mission high-altitude and low-altitude mapping orbits. We established selection criteria to identify craters that were most likely a product of the impact of a binary asteroid. We performed numerical simulations to predict the orientation of the binary craters assuming the population of impactors has mutual orbits coplanar with heliocentric orbits, as the current census of binary asteroids suggests. We compared our simulations with our survey of binary craters on Ceres and Vesta through a Kolmogorov-Smirnov test. Results. We find geomorphological evidence of 39 and 18 synchronous impacts on the surfaces of Ceres and Vesta, respectively. The associated binary asteroids are widely separated and similar in diameter. The distributions of the orientation of these binary craters on both bodies are statistically different from numerical impact simulations that assume binary asteroids with coplanar mutual and heliocentric orbits. Conclusions. Although the identification of binary craters on both bodies and the sample size are limited, these findings are consistent with a population of well-separated and similarly sized binary asteroids with nonzero obliquity that remains to be observed, in agreement with the population of binary craters identified on Mars.

Development of Electrospun Fibres as a Drug Delivery Platform for Antibacterial and Antiviral Technologies
Creators: name: Dart, Alexander
Publisher: name: Swinburne
Year: 2024

description: The rising threat of antibiotic resistance is placing increasing urgency on developing new materials and technologies to dynamically combat resistant infections, particularly for immediate wound care. The research described in this Thesis demonstrates different loading strategies of antimicrobial and antiviral agents into electrospun fibres. Loaded fibres are assessed for their release profiles of active agents, and subsequently the effectiveness on the inhibition of pathogens and the biocompatibility of the fibres in mammalian cell culture. Improved drug delivery of biologically active agents has direct benefits for wound treatment and healthcare medications.
Characterization of the Mpv 20 proviral insertion site and of the Unp gene.

description: Mpv 20 is a transgenic mouse line generated by retroviral infection of embryos in the laboratory of R. Jaenisch. Of the seventy lines generated, only four displayed a recessive lethal phenotype. The fourth line Mpv 17 (Weiher et al. 1990) displays an adult lethal phenotype. The proviral integration site was cloned and a series of genomic clones were isolated from DNA libraries generated from both heterozygote and wild type animals. Using a combination of exon trapping and genomic sequencing of a 3.5 kb region surrounding the proviral integration site, it was determined that the virus integrated into an intron of the murine homologue of the human Npat (Nuclear Protein at the AT locus) gene (accession D83243, U58852, X97186). Northern analysis using a partial murine lung Npat cDNA, generated by RT-PCR, demonstrated on average a reduction of 1.6 fold Npat message in RNA obtained from heterozygote tissues relative to a wild type littermate control. A 5$\sp\prime$ RACE protocol was used to isolate a longer cDNA which was used on Southern blots to examine the possibility of methylation differences between the different animals. Under the experimental conditions utilized, no observable differences were detected between wild type and heterozygote animals. RACE product did however detect a truncated message on a Northern blot present in heterozygote animals but not in the wild type controls. During a search for candidate genes present at the Mpv 20 locus, a cDNA named Unp was isolated (Gupta et al. 1993). The second part of the thesis dealt with the determination of the genomic structure of the Unp gene. The Unp gene was found to be present in 22 exons spanning 47.3 kb and has been assigned the Genbank accession AF026469. All exons, with the exception of exon 1 which contains the transcriptional start site and exon 22 which contains the complete untranslated region, were flanked by the consensus splice acceptor/donor dinucleotides AG/GT (Mount 1982). Compilation of exonic sequences identified the presence of sequencing errors present in the initially published cDNA sequence (Gupta et al. 1993). A 1.1 kb Eco RI/Sac I region upstream of the transcriptional start site was examined for promoter activity using a CAT reporter construct. Low activity was observed in this construct. Surprisingly, a substantial increase in CAT activity was observed when a 556 bp segment at the 5$\sp\prime$ end was deleted from the reporter construct leading us to believe that some repressor element must be present in the deleted region. The promoter fragment lacking the repressor area was found to display activity in both orientations in our experimental assay. (Abstract shortened by UMI.)

description: Barium (Ba) stars help to verify asymptotic giant branch (AGB) star nucleosynthesis models since they experienced pollution from an AGB binary companion and thus their spectra carry the signatures of the slow neutron capture process (s process). For 180 Ba stars, we searched for AGB stellar models that match the observed abundance patterns. We employed three machine learning algorithms as classifiers: a Random Forest method, developed for this work, and the two classifiers used in our previous study. We studied the statistical behaviour of the s-process elements in the observational sample to investigate if the AGB models systematically under- or overpredict the abundances observed in the Ba stars and show the results in the form of violin plots of the residuals between spectroscopic abundances and model predictions. We find a significant trend in the residuals that implies an underproduction of the elements Nb, Mo, and Ru in the models relative to the observations. This may originate from a process (e.g. the intermediate neutron-capture process, i process) at the metallicity of the Ba stars not yet included in the AGB models. Correlations are found between the residuals of these elements, suggesting a common origin for the deviations. In addition, there is a weak metallicity dependence of their residuals. The s-process temperatures derived with the [Zr/Fe] - [Nb/Fe] thermometer have an unrealistic value for the majority of our stars. The most likely explanation is that at least a fraction of these elements are not produced in a steady-state s process, and instead may be due to processes not included in the AGB models. The mass distribution of the identified models confirms that our sample of Ba stars was polluted by low-mass AGB stars. Most of the matching AGB models require low accreted mass, but a few systems with high accreted mass are needed to explain the observations. (abridged)

The redemptive imagination: The fiction of John Irving.

Year: 1998
Subjects: subject: Literature, American.

description: Using Richard Rorty's Contingency, Solidarity and Irony, John Barth's "The Literature of Replenishment," and Christian theology as frames of reference, this thesis argues that Irving recognizes the contingency of language systems which shape our personal and public networks of "beliefs, desires and experiences" and presents the imagination, which enters into, selects, and shapes various public and private "texts," as a moral and unifying force. From The Water-Method Man, The World According to Garp, and The Hotel New Hampshire through to The Cider House Rules, A Prayer for Owen Meany, and A Son of the Circus. Irving's view of the intertextual relationship between the imagination, metafiction and morality evolves. In his later novels, Irving suggests that ironic questioning of "final vocabularies" leads to both personal freedom and an increased tolerance for others. Thus, this thesis argues that Irving employs post-modernist means to present what is, in effect, a Romantic-humanist view of the world.

description: Erythroid enucleation is the process by which the future red blood cell disposes of its nucleus prior to entering the blood stream. This key event during red blood cell development has been likened to an asymmetric cell division (ACD), by which the enucleating erythroblast divides into two very different daughter cells of alternate molecular composition, a nucleated cell that will be removed by associated macrophages, and the reticulocyte that will mature to the definitive erythrocyte. Here we investigated gene expression of members of the Par, Scribble and Pins/Gpsm2 asymmetric cell division complexes in erythroid cells, and functionally tested their role in erythroid enucleation in vivo and ex vivo. Despite their roles in regulating ACD in other contexts, we found that these polarity regulators are not essential for erythroid enucleation, nor for erythroid development in vivo. Together our results put into question a role for cell polarity and asymmetric cell division in erythroid enucleation.
