description: We reformulate the second-order Schrodinger equation as a set of two coupled first order differential equations, a so-called "Shabat-Zakharov system", (sometimes called a "Zakharov-Shabat" system). There is considerable flexibility in this approach, and we emphasise the utility of introducing an "auxiliary condition" or "gauge condition" that is used to cut down the degrees of freedom. Using this formalism, we derive the explicit (but formal) general solution to the Schrodinger equation. The general solution depends on three arbitrarily chosen functions, and a path-ordered exponential matrix. If one considers path ordering to be an "elementary" process, then this represents complete quadrature, albeit formal, of the second-order linear ODE.

description: Construction of the microscopic theory of large-amplitude collective motion, capable of describing a wide variety of quantum collective phenomena in nuclei, is a long-standing and fundamental subject in the study of nuclear many-body systems. Present status of the challenge toward this goal is discussed taking the shape coexistence/mixing phenomena as typical manifestations of the large-amplitude collective motion at zero temperature. Some open problems in rapidly rotating cold nuclei are also briefly discussed in this connection.

description: We performed magnetization and electrical resistivity measurements under high pressures of up to 19 GPa for FeTe0.92. The compound shows an anomaly in magnetization and resistivity at atmospheric pressure due to a structural distortion accompanied by a magnetic transition. We also observed magnetic and resistive anomalies under high pressure, suggesting that two pressure-induced phases exist at a low temperature. Unlike in FeAs-based compounds, no superconductivity was detected under high pressures of up to 19 GPa, although the anomaly at atmospheric pressure was suppressed by applying pressure.

description: We extend the notions of conditioned and controlled invariant spaces to linear dynamical systems over the max-plus or tropical semiring. We establish a duality theorem relating both notions, which we use to construct dynamic observers. These are useful in situations in which some of the system coefficients may vary within certain intervals. The results are illustrated by an application to a manufacturing system.

description: The atomic structure, mechanical and thermodynamic stability of vacancy clusters in Cu are studied by atomistic simulations. The most stable atomic configuration of small vacancy clusters is determined. The mechanical stability of the vacancy clusters is examined by applying uniaxial and volumetric tensile strain to the system. The yield stress and yield strain of the system are significantly reduced comparing to the prefect lattice. The dependence of vacancy formation and binding energy as a function of strain is explored and can be understood from the liquid-drop model. We find that the formation energy of the vacancy clusters decreases monotonically as a function of the uniaxial strain, while the formation energy increases first then decreases under the volumetric tensile strain. The thermodynamic stability of the vacancy clusters is analyzed by calculating the Gibbs free binding energy and the total probability of dissociation of the vacancy clusters at 300 K and 900 K under uniaxial and volumetric strains. We find that although most of the vacancy clusters appear to be thermodynamically stable, some of the immediate sized clusters have high probability of dissociation into smaller clusters.

description: We are developing a purely commensal survey experiment for fast (<5s) transient radio sources. Short-timescale transients are associated with the most energetic and brightest single events in the Universe. Our objective is to cover the enormous volume of transients parameter space made available by ASKAP, with an unprecedented combination of sensitivity and field of view. Fast timescale transients open new vistas on the physics of high brightness temperature emission, extreme states of matter and the physics of strong gravitational fields. In addition, the detection of extragalactic objects affords us an entirely new and extremely sensitive probe on the huge reservoir of baryons present in the IGM. We outline here our approach to the considerable challenge involved in detecting fast transients, particularly the development of hardware fast enough to dedisperse and search the ASKAP data stream at or near real-time rates. Through CRAFT, ASKAP will provide the testbed of many of the key technologies and survey modes proposed for high time resolution science with the SKA.

Subjective response to place through convergent strategies in digital imaging and print processes
Creators: name: Ruffels, Troy
Publisher: name: University Of Tasmania
Year: 2023

description: and Print processes. The project develops visual forms for expressing poetic response to a familiar urban environment. The method evolved uses the convergent potential of digital imaging processes, enabling the development of composite 'metaphoric' imagery, to convey a sense of place. The exposure to habitat provides fleeting and highly subjective insights. Lenscaptured imagery associated with photography and video provides a means to register these incidental truths without breaking the union between mind and place. An additional attraction in using a photographic means of recording source material is the fidelity it brings to the process. Digital imaging technology has now been in use by artists for a sufficient period for the novelty to subside and to permit a mature appraisal of its potential. The considerable flexibility afforded facilitates the accommodation of a diverse range of content and media. The capacity for convergence opens the door to the possibility of bringing together the emotive and expressive warmth of painting and the documentary coolness of photography. The advantage of encompassing 'warm' and 'cool' approaches is the space it allows for both the subject and the subjective to interact. As these ideas evolved during the studio investigation, it became apparent that it was the immediacy afforded by the free application of oil paint, which permits the artist to give spontaneous expression to their subjective vision. Although there were to be time lags between the various steps in the methodology for this project, spontaneity within each step was given a high priority. These aims have been pursued through digital imaging processes with photography and painting, culminating in digital prints. Methodologies, exploring the convergent potential of digital technology for representing subjective response to intimacies uncovered in nature, were developed using both still and video cameras, commercial image manipulation software, a range of media and three generations of digital printers. Hobart and its environment was the chosen site for engagement because this incorporates urban, parkland, hill country and waterfrontage. Also, it was familiar territory and conveniently accessible. The methodology requires many repeat visits to selected sites. The main parameters for the project include the above environment and the still, two-dimensional image. The context, working processes and image developments are discussed in the body of the exegesis.

Maritime communication in an international and intercultural discourse
Creators: name: Schriever, UG
Publisher: name: University Of Tasmania
Year: 2023

description: The international maritime industry consists of a global web of shipping that covers the oceans and connects all continents on the earth. It brings together seafarers from a multitude of national, ethnic and linguistic backgrounds. The English language has emerged as the lingua franca of the sea. By consensus - and, indeed, by UN resolution - it is the most common means through which communication takes place wherever language barriers exist. This thesis explores the views mariners have on a common language and the English language in that role. It tries to identify non-English speaking background (NESB) people who appear to have greater difficulties in communicating in the tongue, and it investigates the possible existence of cultural, religious, ideological or political reasons for an aversion to English. It also makes an attempt to determine the usefulness of a standard coded language as in the Standard Maritime Communication Phrases (SMCP) and seeks to gain information about incidents in which misunderstanding played a part. It further tries to elicit statements from seafarers about English language proficiency among their colleagues in the industry and about a skill level to be attained by different ranks. The research was carried out using a qualitative and a quantitative approach. Twelve interviews with seafarers and marine pilots were conducted and 132 questionnaires received from members of 17 different nationalities. In addition, four case studies were examined and an observation by the author on a recent voyage from Singapore to Australia was described. The result of the investigation shows the overwhelming acceptance of English as the common means of communication, reveals several language groups which are perceived as hard to communicate with using maritime English, and finds some evidence of a resistance to the language. It also shows that the SMCP is not used to its full potential and that misunderstandings due to verbal and cultural barriers are still firmly in place. The present level of English proficiency is widely considered as wanting, and officers in particular were expected to reach a more advanced level of competence in the language.
Baffin Island sandar : a study of arctic fluvial environments
Creators: name: Church, Michael
Publisher: name: University of British Columbia
Year: 2010

description: Sandur (pl. sandar) is a sand, or gravel plain deposited by a rapidly aggrading, braided river. Valley sandar form the major postglacial physiographic feature in much of the Canadian Arctic. The conditions favorable for sandur development: presence of an abundant supply of detrital material and the occurrence of relatively frequent floods competent to move the material, are characteristic of proglacial and eome periglacial environments. Such conditions occur in central Baffin Island. Nival floods, summer ice-melt floods, and summer storm runoff generate significant sediment transport events. Storm runoff is particularly effective in the Arctic since there is little vegetation and the substrate is frozen, so that a high proportion of rainfall runs off immediately. The distribution of runoff events shows a disproportionate number of moderately high flows. Very active sandar are characterised by occasional extreme floods produced by catastrophic drainage of ponded water from Ice margins. Sediment transport is mainly bedload, though solution and suspended load are considerable. Transport is much greater than the rate of primary detritus production as large volumes of glacially derived material are being redistributed. Movement of extraordinary volumes of material is characteristic of the transition period from one environment (glacial) to another (fluvial). Sandur streams are extremely vide and shallow, a characteristic of bedload transporting channels. The major hydraulic adjustment to increasing discharge is made by stream velocity, indicating a sharp decline in flow resistance associated with the rapid increase of sediment transport and consequent change in the nature of the stream boundary. The long profiles of the streams are approximately parabolic: this form is probably conditioned by the nature of the aggradation on the surface as a whole. The sequence of pools and riffles along the channels constitute a fundamental feature of the river. They appear to function as regulators of energy expenditure in the stream and concomitantly influence flow resistance and the movement and storage of sediment. The sandur surface is a purely aggradational feature. Erosion and deposition occur over wide areas during major floods. Change of stage is rapid so that deposition is often chaotic, and little internal structure occurs in the sediments. Significant pattern is found only in the mean size and variance of coarse materials(cobbles), Indicating deposition under conditions of declining competence downsandur. Study of a former sandur, and of deltaic beds at its distal end, indicate that environmental conditions throughout much of postglacial time have not been dissimilar from the present ones. The more extensive sedimentation that occurred in earlier postglacial tine should be attributed to greater event duration, or to greater availability of detritus, rather than to the occurrence of appreciably greater events.
Leadership roles for women in the eighteenth century Methodist revival, and in particular, female preaching
Creators: name: Schuth, Veronica M
Publisher: name: University Of Tasmania
Year: 2023

description: This thesis examines and analyses the circumstances that led to women finding more opportunity for involvement in leadership roles in the eighteenth century Methodist revival and considers Wesley's changing views which allowed the evolution of female preaching. The pertinent period concerned is from c.1740 to c.1805 during which time women's involvement in Wesleyan Methodism reached its peak, particularly in relation to 'female preaching', and was summarily quashed by the introduction of a more formal denominational structure in the first decade of the nineteenth century.
Stable configurations of hybrid stars with colour-flavour-locked core

description: We construct static and mass-shedding limit sequences of hybrid stars, composed of colour flavour locked (CFL) quark matter core, for a set of equations of state (EOSs). The EOS for the hadronic matter is obtained using appropriately calibrated extended field theoretical based relativistic mean-field model. The MIT bag model is employed to compute the EOSs of the CFL quark matter for different values of the CFL gap parameter in the range of $50 - 150\text{MeV}$ with the deconfinement phase transition density ranging from $4ρ_0 - 6ρ_0$ ($ρ_0 = 0.16\text{fm}^{-3}$). We find, depending on the values of the CFL gap parameter and the deconfinement phase transition density, the sequences of stable configurations of hybrid stars either form third families of the compact stars or bifurcate from the hadronic sequence. The hybrid stars have masses $1.0 - 2.1 M_\odot$ with radii $9 - 13.5$ km. The maximum values of mass shedding limit frequency for such hybrid stars are $1 -2$ kHz. For the smaller values of the CFL gap parameter and the deconfinement phase transition density, mass-radius relationships are in harmony with those deduced by applying improved hydrogen atmosphere model to fit the high quality spectra from compact star X7 in the globular cluster 47 Tucanae. We observed for some cases that the third family of compact stars exist in the static sequence, but, disappear from the mass-shedding limit sequence. Our investigation suggests that the third family of compact stars in the mass-shedding limit sequence is more likely to appear, provided they have maximum mass in the static limit higher than their second family counterpart composed of pure hadronic matter.

Indirect Dark Matter Searches in the Light of ATIC, FERMI, EGRET and PAMELA

Subjects: subject: Cosmology and Nongalactic Astrophysics (astro-ph.CO)

description: Recently, new data on antiprotons and positrons from PAMELA, e- + e+ spectra from ATIC, FERMI and HESS up to TeV energies all indicate deviations from expectations, which has caused an interesting mix of new explanations, ranging from background, standard astrophysical sources to signals from dark matter (DM) annihilation. Unfortunately, the excess in positrons is not matched with obvious excesses in antiprotons or gamma rays, so a new class of DM scenarios with leptophilic WIMP candidates have been invoked. On the other hand, the increase in the positron fraction, which could have had any spectral shape for new physics, matches well the shape expected from proton background.

description: This study examines the shock speed and source height of coronal shock waves using Type II solar radio bursts. The solar radio burst data from January 2022 to October 2023 were obtained from eCALLISTO archive. The type II radio bursts were isolated from the spectra through a rigorous noise reduction process by taking the maximum intensity of each time channel. Using plasma oscillations and electron density models for the solar corona, explicit expressions for shock speed and source height were obtained. From the dynamic spectra, the starting frequency of a burst was obtained and using these parameters shock speed and source height were calculated. Results confirmed shock speeds ranging from 343 to 1032 kms$^{-1}$ with average speed of 650$\pm$226 kms$^{-1}$ and source heights 1.317-1.724 R$_\odot$, with high precision in formula predictions. The study highlights the need for broader burst type inclusion in future research and underscores the efficacy of the developed methodologies to improve space weather forecasts.

description: In Iran, as in other developing countries, the existence of shrinking cities has been observed. In the case of 13 medium-sized cities in Khuzestan province in 1977–2011, demographic growth trends differ widely, but there was no significant overall relationship between urban population growth and employment, activity development or indeed with indicators of social environmental and ecological development in these cities. Demographic growth is principally a result of natural increase and intra-regional rural–urban migration in a geopolitically important but relatively disadvantaged border province that suffers from net outmigration and the devastating effects of the Iran–Iraq War on the distribution of the population, infrastructure and important economic centres, and ports such as Abadan.

The petrology of the Cambrian volcanic rocks of Tasmania

Year: 2023

description: A spilitic suite comprising picrite basalts, spilites, keratophyres, albite dolerites and associated pyroclastics reputed to be Middle Cambrian in age forms an interesting petrographic province on the West Coast of Tasmania. The spilites are considered to have been normal basalts which later suffered soda metasomatism as a result of eugeosynclinal orogeny. Like basalts from other orogenic regions these are rich in alumina but the presence of excess alumina in this suite is regarded as being secondary and not magmatic. Fresh diopsidic augite is a feature of some of the lavas. Hydrothermal alteration has given rise to a variety of rock types which includes porphyries, kerntophyres, variolite‚ÄövÑvp, spherulitic quartz rock and jasper. Petrological-similarity exists in basaltic lavas in Tasmania, South Australia and Western Australia but the Tasmanian lavas which are eugeosynclinal show advanced metasomatic alteration whereas the Western Australian, which were erupted on to the stable shield are unaltered. The South Australian, which are miogeosyncinal, are partially metasomatised.

description: We study the metric $f(R)$ cosmology using Noether symmetry approach by utilizing the behavior of the corresponding Lagrangian under infinitesimal generators of the desired symmetry. The existence of Noether symmetry of the cosmological $f(R)$ minisuperspace helps us to find out the form of $f(R)$ function for which such symmetry exist. It is shown that the resulting form for $f(R)$ yields a power law expansion for the cosmic scale factor. We also show that in the corresponding Noether symmetric quantum model, the solutions to the Wheeler-DeWitt equation can be expressed as a superposition of states of the form $e^{iS}$. It is shown that in terms of such wavefunctions the classical trajectories can be recovered.

A partir de una acción formativa donde estos dispositivos son los medios protagonistas, y de una encuesta previa y posterior a esta acción, se presenta un análisis sobre el cambio en el uso y la percepción producido, indicando la necesidad de introducir estas herramientas en el aula para el beneficio que los mismos estudiantes perciben. Los resultados permiten reflexionar sobre la necesidad de repensar los planes docentes en los grados de comunicación, específica[1]mente ante las competencias técnicas relativas a la creación audiovisual con dispositivos móviles. Los resultados relacio[1]nados con la necesidad de formación recibida por los estudiantes y su aceptación de las herramientas en un sentido profesio[1]nal marca la discusión futura sobre su implementación en educación superior en medios audiovisuales.

description: Eine HPV-Impfung wird von der Ständigen Impfkommission (STIKO) für Jungen und Mädchen im Alter zwischen 9 und 14 Jahren empfohlen. Die Impfung kann eine Ansteckung mit Hochrisiko-HPV-Typen, insbesondere HPV 16 und 18, verhindern und damit das Risiko für Gebärmutterhalskrebs und andere Tumoren z.B. an Vulva, Scheide, Penis, After und im Mund-Rachen-Bereich deutlich senken. Die vorgestellte Unterrichtseinheit soll die Schülerinnen und Schüler durch fundierte und verständliche Informationen dabei unterstützen eine persönliche, begründete Entscheidung für oder gegen eine Impfung zu treffen. Grundlage dieser Entscheidung sind neben den bereitgestellten Informationen auch selbst recherchierte Fakten. Daher wird auch das Überprüfen von Internetseiten auf Glaubwürdigkeit und Seriosität thematisiert und so insbesondere die digitale Gesundheitskompetenz gestärkt.

Absorption of amino acids In vitro by the rectum of the desert locust (Schistocerca gregaria)
Creators: name: Balshin, Michael
Publisher: name: University of British Columbia
Year: 2011

description: Rectal sacs of Schistocerca gregaria Forskal adults are capable of active absorption of those neutral amino acids naturally found in locust hemolymph. This absorption occurs against large electrochemical gradients, is inhibited by KCN, and is enhanced only slightly by solvent flow. Metabolic conversion of the amino acids during the translocation across the epithelium is not significant. The site of active absorption appears to be located on the apical border of the epithelium. Exit of the amino acids from the epithelium to the hemolymph may occur by passive diffusion. The absorptive process exhibits stereo-specificity, saturation kinetics, and competitive inhibition. Relative rates of absorption of different amino acids correlate approximately with their relative abundance in the hemolymph. A reciprocal correlation is found between the absorption rate and the length of the hydrocarbon side chain of the transported amino acid. The glycine transport system across the rectal wall involves a large Na⁺ dependent and a small Na⁺ independent component. Partial inhibition of glycine uptake is observed when CI⁻ or K⁺ are omitted from the incubation medium. The Na⁺ dependence of net ¹⁴C-glycine uptake into the rectal epithelium from the lumen is a consequence of both an increase in influx and decrease in efflux. The tissue concentration of Na⁺ is not affected by the presence or absence of external glycine. Net transfer of glycine across KCN poisoned rectal sacs is not reversed upon reversal of the Na⁺ concentration gradient. The present work suggests the involvement of a specific carrier in the mechanism of active transport of amino acids by the locust's rectum. It would be premature to assess, however, whether the translocation of amino acids is a primary transport process, or a secondary one coupled to net Na⁺ fluxes across the rectal wall. Nonetheless, the presence of such a mechanism would suggest that the rectum plays an important role in the regulation of amino acid levels in the hemolymph of insects.

Photoabsorption by Volume Plasmons in Metal Nanoclusters

description: It is well known that plasmons in bulk metals cannot be excited by direct photoabsorption, that is, by coupling of volume plasmons to light. Here we demonstrate that the situation in nanoclusters of the same metals is entirely different. We have carried out a photodepletion measurement for Na_20 and Na_92 and identified a broad volume plasmon absorption peak centered slightly above 4 eV, revealing the possibility of optical excitation of volume-type collective electronic modes in a metallic system. The observed phenomenon is related to different selection rules for finite systems.
Reappraising forgotten fictions : the Tasmanian romances of Marie Bjelke Petersen
Creators: name: Sherwood, TA
Publisher: name: University Of Tasmania
Year: 2023

description: Marie Bjelke Petersen was a prolific writer of popular romance fiction in the early twentieth century. This thesis analyses her five Tasmanian based novels. Although popular with her contemporary reading public, the novels have been critically marginalized in the Australian literary tradition and they now languish largely unread. The work of Susan Sheridan, Fiona Giles and Robert Dixon provides a theoretical context in which Bjelke Petersen's fiction can be re-read and reappraised, for these critics identify an Australian romance tradition that is continuous, prolific and diverse. More importantly, they demonstrate such texts can be recuperated as important cultural artefacts, which articulate and debate in popular form the inherent anxieties, interests and concerns of a culture, at a particular time. The thesis consists of an introduction, three chapters and a conclusion. The first chapter demonstrates Bjelke Petersen's competence as a writer of popular fiction and argues against claims of aesthetic inadequacy. John Cawelti's work on formula fiction and Rita Felski's formulation of the popular sublime provide the theoretical basis for this chapter. The second chapter considers the representation of love and romance in Bjelke Petersen's texts. It identifies a re-imagining of the roles of heroines and heroes and a strong commitment to promoting the ideal of companionate love. It argues that such representation is influenced by mainstream feminist campaigns for women's greater agency but also reflects less widely circulated discourses about sexuality. The third chapter focuses on Bjelke Petersen's preoccupation with Tasmanian wilderness as a form of \literary placemaking.\" In each of her novels wilderness is constructed as a place of freedom adventure healing and love: a haven from modernity. This chapter evaluates and historicizes Bjelke Petersen's representation oflandscape. It concludes that Bjelke Petersen's writing whilst mindful of generic convention is also informed by local knowledge and strives to communicate a sense of aesthetic appreciation for nature. The capacity of wilderness to engender physical and spiritual wellbeing - characteristic of romantic ideology - is here compromised by discourses of evangelical religion. The thesis concludes that Bjelke Petersen's romances when considered outside the narrow framework of an Australian realist nationalist tradition are important as popular cultural artefacts. These texts reflect a variety of marginalized early twentieth-century discourses and demonstrate the diversity and complexity of Australian literary culture in this period."

description: Initiation of PINK1- and PRKN-dependent mitophagy is a highly regulated process involving the activity of the AAA-ATPase VCP/p97, a cofactor-guided multifunctional protein central to handling ubiquitinated client proteins. Removal of ubiquitinated substrates such as the mitofusin MFN2 from the outer mitochondrial membrane by VCP is critical for PRKN accumulation on mitochondria, which drives mitophagy. Here we characterize the role of the UBA and UBX-domain containing VCP cofactor UBXN1/SAKS1 during mitophagy. Following mitochondrial depolarization and depending on PRKN, UBXN1 translocated alongside VCP to mitochondria. Prior to mitophagy, loss of UBXN1 led to mitochondrial fragmentation, diminished ATP production, and impaired ER-mitochondrial apposition. When mitophagy was induced in cells lacking UBXN1, mitochondrial translocation of VCP and PRKN was impaired, diminishing mitophagic flux. In addition, UBXN1 physically interacted with PRKN in a UBX-domain depending manner. Interestingly, ectopic expression of the pro-mitophagic VCP cofactor UBXN6/UBXD1 fully reversed impaired PRKN recruitment in UBXN1-/- cells. Mechanistically, UBXN1 acted downstream of PINK1 by facilitating MFN2 removal from mitochondria. In UBXN1-/- cells exposed to mitochondrial stress, MFN2 formed para-mitochondrial blobs likely representing blocked intermediates of the MFN2 removal process partly reversible by expression of UBXN6. Presence of these MFN2 blobs strongly correlated with impaired PRKN translocation to depolarized mitochondria. Our observations connect the VCP cofactor UBXN1 to the initiation and maintenance phase of PRKN-dependent mitophagy, and indicate that, upon mitochondrial stress induction, MFN2 removal from mitochondria occurs through a specialized process.

description: We determine the phase transition of the Levy spin glass. A regularized model where the coupling constants smaller than some cutoff $ε$ are neglected can be studied by the cavity method for diluted spin glasses. We show how to handle the $ε\to 0$ limit and determine the de Almeida-Thouless transition temperature in presence of an external field. Contrary to previous findings, in zero external field we do not find any stable replica-symmetric spin glass phase: the spin glass phase is always a replica-symmetry-broken phase.
