description: It is shown that a commutative Bézout ring $R$ with compact minimal prime spectrum is an elementary divisor ring if and only if so is $R/L$ for each minimal prime ideal $L$. This result is obtained by using the quotient space $\mathrm{pSpec} R$ of the prime spectrum of the ring $R$ modulo the equivalence generated by the inclusion. When every prime ideal contains only one minimal prime, for instance if $R$ is arithmetical, $\mathrm{pSpec} R$ is Hausdorff and there is a bijection between this quotient space and the minimal prime spectrum $\mathrm{Min} R$, which is a homeomorphism if and only if $\mathrm{Min} R$ is compact. If $x$ is a closed point of $\mathrm{pSpec} R$, there is a pure ideal $A(x)$ such that $x=V(A(x))$. If $R$ is almost clean, i.e. each element is the sum of a regular element with an idempotent, it is shown that $\mathrm{pSpec} R$ is totally disconnected and, $\forall x\in\mathrm{pSpec} R$, $R/A(x)$ is almost clean; the converse holds if every principal ideal is finitely presented. Some questions posed by Facchini and Faith at the second International Fez Conference on Commutative Ring Theory in 1995, are also investigated. If $R$ is a commutative ring for which the ring $Q(R/A)$ of quotients of $R/A$ is an IF-ring for each proper ideal $A$, it is proved that $R_P$ is a strongly discrete valuation ring for each maximal ideal $P$ and $R/A$ is semicoherent for each proper ideal $A$.

description: We propose the complex group theoretical Clebsch-Gordon coefficients as a novel origin of CP violation. This is manifest in our model based on SU(5) combined with the T' group as the family symmetry. The complex CG coefficients in T' lead to explicit CP violation which is thus geometrical in origin. The predicted CP violation measures in the quark sector are consistent with the current experimental data. The corrections due to leptonic Dirac CP violating phase gives the experimental best fit value for the solar mixing angle, and we also gets the right amount of the baryonic asymmetry.

title: The Oneida Community: Its Apologists and its Critics
Creators: name: Morris, Nancy C.
Publisher: name: Old Dominion University Libraries
Year: 1985

description: This thesis examines the historical literature regarding the Oneida Community (1848-81) from the society's conceptual beginnings in the 1830s to the present time. After an overview of the antebellum communitarian movement in the United States, a detailed description of the Oneida Community, one of America's most prominent nineteenth-century utopian experiments, is presented.

Chapters III, IV, and V survey the body of literature pertinent to the Oneida Community and its founder and spiritual leader, John Humphrey Noyes, over the last 145 years. The writings of the Oneida apologists, a majority of whom were Oneida Community family members and their descendants, are examined chronologically in Chapter III. In contrast, Chapter IV emphasizes the negative commentary on Oneida by "outsiders" dating from the late 1840s through the 1950s. It also highlights the favorable criticism formulated in these same years. The fifth and final chapter illustrates that contemporary opinion since 1960 has generally been favorable to the Oneida experiment, perhaps influenced by the social mores of the twentieth century.

description: We investigate the correlation between far-infrared (FIR) and radio luminosities in distant galaxies, a lynchpin of modern astronomy. We use data from the Balloon-borne Large Aperture Submillimetre Telescope (BLAST), Spitzer, the Large Apex BOlometer CamerA (LABOCA), the Very Large Array (VLA) and the Giant Metre-wave Radio Telescope (GMRT) in the Extended Chandra Deep Field South (ECDFS). For a catalogue of BLAST 250-micron-selected galaxies, we re-measure the 70--870-micron flux densities at the positions of their most likely 24-micron counterparts, which have a median [interquartile] redshift of 0.74 [0.25, 1.57]. From these, we determine the monochromatic flux density ratio, q_250 = log_10 (S_250micron / S_1400MHz), and the bolometric equivalent, q_IR. At z ~= 0.6, where our 250-micron filter probes rest-frame 160-micron emission, we find no evolution relative to q_160 for local galaxies. We also stack the FIR and submm images at the positions of 24-micron- and radio-selected galaxies. The difference between q_IR seen for 250-micron- and radio-selected galaxies suggests star formation provides most of the IR luminosity in ~< 100-uJy radio galaxies, but rather less for those in the mJy regime. For the 24-micron sample, the radio spectral index is constant across 0 < z < 3, but q_IR exhibits tentative evidence of a steady decline such that q_IR is proportional to (1+z)^(-0.15 +/- 0.03) - significant evolution, spanning the epoch of galaxy formation, with major implications for techniques that rely on the FIR/radio correlation. We compare with model predictions and speculate that we may be seeing the increase in radio activity that gives rise to the radio background.

Some fundamental aspects of static friction
Creators: name: Green, Marjorie Ann
Publisher: name: University of British Columbia
Year: 2011

description: The present report summarizes the results of an experimental study of static friction. Stick-slip type vibration was produced in a pin on disk friction system in order to determine the effect of various parameters on the static friction force. In the first part of the study it was found that two distinct types of sliding behaviour could be produced by controlling the preparation of the surfaces prior to sliding. If the surfaces were freshly polished and kept relatively free of organic contaminants then the sliding behaviour was characterized by high friction coefficients and extensive surface damage. Under lubricated conditions however, stick-slip vibration was possible at low driven surface velocities. These results show the importance of surface history with regard to friction phenomena and aid in the interpretation of subsequent experimental results. By measuring the electrical resistance of the slider-disk interface it was possible to monitor changes in the area of contact during stick-slip. It was observed that there was metallic contact throughout the complete cycle although the amount of metallic contact varied. The stick portion of the cycle was found to be a region of increasing metallic contact. The amount of metallic contact area at slip was a function of the rate at which the tangential force was applied. During slip, the area in metallic contact decreased rapidly and there was some evidence that the normal load on the slider was partially supported by a lubricant film in this part of the cycle. The amount of contact during slip was determined by the relative velocity during slip. By monitoring the resistance of the interface during a "delayed" stick cycle it was possible to show that the area in contact did not increase with time under a stationary loading condition. Instead the area of contact at slip and also the static friction force were found to be dependent on the rate of application of the tangential force. These findings contradict earlier work on time-dependent creep models for static friction and provide additional evidence in support of the visco-elastic model proposed by Johannes [27].

System size dependence of associated yields in hadron-triggered jets

description: We present results on the system size dependence of high transverse momentum di-hadron correlations at $\sqrt{s_{NN}}$ = 200 GeV as measured by STAR at RHIC. Measurements in d+Au, Cu+Cu and Au+Au collisions reveal similar jet-like correlation yields at small angular separation ($Δϕ\sim0$, $Δη\sim0$) for all systems and centralities. Previous measurements have shown that the away-side yield is suppressed in heavy-ion collisions. We present measurements of the away-side suppression as a function of transverse momentum and centrality in Cu+Cu and Au+Au collisions. The suppression is found to be similar in Cu+Cu and Au+Au collisions at a similar number of participants. The results are compared to theoretical calculations based on the parton quenching model and the modified fragmentation model. The observed differences between data and theory indicate that the correlated yields presented here will provide important constraints on medium density profile and energy loss model parameters.

description: Inúmeras são as discussões acerca do termo letramento. Há teóricos que dividem o letramento em duas categorias: autônomo e ideológico. O letramento autônomo, segundo Tfouni (2010, p. 36), “é visto como causa, tendo como suporte a escolarização”. Suas consequências seriam o desenvolvimento econômico e habilidades cognitivas, como, por exemplo, flexibilidade para mudar de perspectiva. O modelo autônomo sugere que o letramento possibilita diferenciar as “funções lógicas” da linguagem das funções interpessoais e também propõe que todas as aquisições citadas estariam intimamente ligadas com os poderes intrínsecos da escrita, entre os quais se encontrariam as possibilidades de separação entre o sujeito que conhece o objeto conhecido, as habilidades metacognitivas e a capacidade de descontextualização.

description: We investigate the two-dimensional kpc-scale structure of the extinction in a representative sample of local ULIRGs using the Halpha/Hbeta line ratio.We use optical integral field spectroscopy obtained with the INTEGRAL instrument at the William Herschel Telescope. Complementary optical and near-IR high angular resolution HST images have also been used. The extinction exhibits a very complex and patchy structure in ULIRGs on kpc scales, from basically transparent regions to others deeply embedded in dust (Av~0.0 to Av~8.0 mag). Nuclear extinction covers a broad range in Av from 0.6 to 6 mag, 69% of the nuclei having Av>2.0 mag. Extinction in the external regions is substantially lower than in the nuclei with 64% of the ULIRGs in the sample having median Av of less than 2 mag for the entire galaxy. While post-coalescence nuclei tend to cluster around Av values of 2 to 3 mag, pre-coalescence nuclei appear more homogeneously distributed over the entire 0.4 mag

description: We present the first quantitative experimental evidence for the underscreened Kondo effect, an uncomplete compensation of a quantized magnetic moment by conduction electrons, as originally proposed by Nozieres and Blandin. The device consists of an even charge spin S = 1 molecular quantum dot, obtained by electromigration of C60 molecules into gold nanogaps and operated in a dilution fridge. The persistence of logarithmic singularities in the low temperature conductance is demonstrated by a comparison to the fully screened configuration obtained in odd charge spin S = 1/2 Coulomb diamonds. We also discover an extreme sensitivity of the underscreened Kondo resonance to magnetic field, that we confirm on the basis of numerical renormalization group calculations.

A study to develop an instrument to assist nurses to assess the abilities of patients with chronic conditions to feed themselves
Creators: name: Phillips, Frances Patricia
Publisher: name: University of British Columbia
Year: 2011

description: Construction of a tool to assist nurses to assess the abilities of patients, with chronic conditions, to feed themselves was based upon twenty-one identified feeding behaviors derived from observations of a random sample of fifty such patients from two urban hospitals. Observations were also made of the nurses who cared for these patients. Identifying specific behavior items was concurrent with defining five categories along the dependence-independence continuum during analysis of the data. A 3:1:1 ratio for weighting behavioral components was established arbitrarily. The Kenny Self-care five point numerical rating scale was adapted to provide a method of determining the amount of help a patient would require to feed himself. Experts in the field agreed, with minor modifications, that the tool could determine a measure of independent feeding. A reliability test, using eight pairs of registered nurses to assess thirty-two patients produced a reliability coefficient of .849; evidence that this tool is dependable and consistent in measuring the relative state of feeding dependence-independence of patients with chronic conditions. Rating behaviors provides written evidence of the degree to which the patient is able to feed himself. The difference between what a patient can do and the criteria for independent feeding provides a measure of the help a patient will require to feed himself. Further research is indicated in the areas of usefulness of the tool for registered nurses, identifying psychosocial behaviors more precisely, testing the tool in different feeding situations and expansion of the tool to include the other activities of daily living.
Patents for pharmaceuticals and access to affordable medicines: towards an all-encompassing access paradigm for Africa
Creators: name: Owoeye, OA
Publisher: name: University Of Tasmania
Year: 2023

description: The connection between patents for pharmaceuticals and access to affordable medicines has elicited considerable attention and highly stimulating debates since the emergence of the World Trade Organisation (WTO) Agreement on Trade Related Aspects of Intellectual Property Rights (the TRIPS Agreement) as part of the Marrakesh Agreement Establishing WTO in 1994. The TRIPS Agreement is the first international convention to make it mandatory for all countries to make patents available in all fields of technology provided the invention to be patented meets the criteria for patentability. Consequently, countries like India, Brazil, China and Thailand that used to refuse to grant patents for pharmaceuticals were constrained to amend their patents laws to bring them in line with the WTO standard. Many developing countries did not even have legislation for a number of the intellectual property rights areas covered by the agreement at the time it was adopted. The TRIPS Agreement has been criticised as being a significant part of the global access to medicines problem and strong arguments have been raised for having more flexible standards for the protection of patents particularly in relation to pharmaceuticals. This thesis examines the WTO regime for patent protection in the context of pharmaceuticals and the existing flexibilities in the TRIPS Agreement that countries seeking access to affordable patented pharmaceutical products might adopt. The effectiveness of the TRIPS compulsory licensing regime is examined, with particular focus on the limitations resulting from the TRIPS requirements for test data protection. The concepts of parallel importation and exhaustion of intellectual property (IP) rights are also examined with aview to ascertaining the extent to which they may serve as legal stratagems for developing countries seeking access to affordable medicines. The thesis argues that the existing frameworks for the right to health and the right to development in international law may provide a strong justification for the broad interpretation of the existing flexibilities in the TRIPS Agreement without the need for going through the very rigorous process of amending it. The thesis considers the patents and access to medicines problem in the context of the special and highly complex challenges people in Sub-Sahara Africa are currently encountering. It recommends the establishment of an African Free Trade Area to make it easier for Africa as a continent to make better use of the TRIPS flexibilities. The thesis argues that more than ever before, the time has come for Africa to harness her resources to address her access to medicines problem through the use of all the available options in international economic law and international human rights law.

description: Chemical networks used for models of interstellar clouds contain many reactions, some of them with poorly determined rate coefficients and/or products. In this work, we report a method for improving the predictions of molecular abundances using sensitivity methods and ab initio calculations. Based on the chemical network osu.2003, we used two different sensitivity methods to determine the most important reactions as a function of time for models of dense cold clouds. Of these reactions, we concentrated on those between C and C3 and between C and C5, both for their effect on specific important species such as CO and for their general effect on large numbers of species. We then used ab initio and kinetic methods to determine an improved rate coefficient for the former reaction and a new set of products, plus a slightly changed rate coefficient for the latter. Putting our new results in a pseudo-time-dependent model of cold dense clouds, we found that the abundances of many species are altered at early times, based on large changes in the abundances of CO and atomic C. We compared the effect of these new rate coefficients/products on the comparison with observed abundances and found that they shift the best agreement from 3e4 yr to (1-3)e5 yr.

These resources are and will be designed to cover the use of NFDI4Earth services and principles in Research Data Management (RDM) and Earth System Data Science (ESDS). The initial set of NFDI4Earth-ready course materials has been published under an open license, leveraging the Open edX Tutor Instance.The Open edX-based NFDI4Earth educational portal houses content developed by the EduTrain team as well as materials from the first round of NFDI4Earth educational pilots. A content library is also under development to streamline course creation and maintain consistency across courses. Two courses, namely "Image Processing and Analysis" and "How to create publishable NetCDF-data", have been published and made accessible to the public, with more in the pipeline. A cornerstone of the project is the adoption of open licenses, particularly the Creative Commons Attribution (CC-BY) license, for all course modules. This licensing strategy ensures the widest possible dissemination and use of educational resources. Challenges encountered during the project are systematically recorded and addressed in the EduTrain project within the NFDI4Earth GitLab. The report concludes with the project's future direction, which includes enhancing platform interactivity, expanding the course catalogue, refining the curriculum, and continuously improving the learner experience.

description: We investigate theoretically the evolution of the two-point density correlation function of a low-dimensional ultracold Bose gas after release from a tight transverse confinement. In the course of expansion thermal and quantum fluctuations present in the trapped systems transform into density fluctuations. For the case of free ballistic expansion relevant to current experiments, we present simple analytical relations between the spectrum of ``density ripples'' and the correlation functions of the original confined systems. We analyze several physical regimes, including weakly and strongly interacting one-dimensional (1D) Bose gases and two-dimensional (2D) Bose gases below the Berezinskii-Kosterlitz-Thouless (BKT) transition. For weakly interacting 1D Bose gases, we obtain an explicit analytical expression for the spectrum of density ripples which can be used for thermometry. For 2D Bose gases below the BKT transition, we show that for sufficiently long expansion times the spectrum of the density ripples has a self-similar shape controlled only by the exponent of the first-order correlation function. This exponent can be extracted by analyzing the evolution of the spectrum of density ripples as a function of the expansion time.

Spectral analysis of early F-type supergiants

Publisher: name: University Of Tasmania
Year: 2023

description: High or moderately-high dispersion spectra covering the wavelength interval 3800A¬¨‚àû to 5000A¬¨‚àû were obtained for ten luminous early F-type stars and an F8Ia supergiant south of declination -15¬¨‚àû . These spectroscopic plates have been used to measure line blocking, the profiles of the strongest lines (hydrogen and calcium K), and to determine the equivalent widths of as many metal lines as possible in this wavelength range. The line blocking measurements, hydrogen-line profiles and scanner or ubvy photometry data have been used with model atmosphere predictions to determine effective temperatures and gravities. A discrepancy between the gravity indicated by the Balmer jump and the Hy line profiles has been found in the most luminous stars. The gravities determined from the H profiles have been compared with the gravities derived from cluster members and there is found to be a small discrepancy, the gravities from the profiles being lower. Some evidence for the presence of macroscopic turbulent motions in the more luminous early F Ia stars and A Ia stars is presented, and it is shown that the inclusion of a turbulent pressure term in the equation of hydrostatic equilibrium largely removes the discrepancy between the gravity indicated by the Hy profiles and that indicated by the cluster members. A study of the rotational velocities of the program stars show that the early F Jab and lb stars exhibit very little or no macroturbulence. The observed rotational velocity of 0 Sco (a lb supergiant) shows that this star must have lost very little of its angular momentum during its evolution off the main sequence and must have rotated as a rigid body for some, if not all, of this phase of its evolution.

Homing behaviour of an inter-tidal fish Oligocottus maculosus girard
Creators: name: Khoo, Hong Woo
Publisher: name: University of British Columbia
Year: 2011

description: The purpose of the study is to find out how Oligocottus maculosus homes and what mechanisms or sensory channels are involved in the homing process. The species' home range was defined from pool fidelity and movement observations. Evidence was obtained to show that the fish homes when displaced to unfamiliar areas. The roles of season, distance and direction of displacement as well as sex, size and experience of the fish in homing were assessed. The roles of both vision and olfaction and the related environmental cues were also investigated. Some fish showed strict fidelity to specific tide-pools while others moved from one pool to another but limited themselves to a restricted group of neighbouring pools. The range of movement seldom exceeded an area of about one hundred square feet which was defined as the maximum home range. Homing, i.e. striving to return to its home range instead of going to other equally habitable areas, was observed throughout the year; homing was most successful between March and August. This seasonal variation was probably the result of mortality owing to the seasonal sea conditions. In my study O. maculosus had been shown to home from as far as one thousand feet. A decrease in homing returns with increasing distances from home was observed. This was attributed to the effects of wave action which decreased the chances of survival with increasing distances from home. Direction of displacement did not seem to affect homing performance and no difference in homing performance was observed between the sexes or among fish of different sizes. Fish which were shown to home at least once seemed to home better than naive fish though no further improvement in homing was observed when the former were repeatedly displaced. There is a strong indication that there is inherent variability in homing ability, that some fish home better than others and that learning per se is not important. Displacement experiments conducted with blind and anosmic fish had shown that blind fish could home better than anosmic fish indicating that olfaction, not vision, is more important in homing. Studies on the ability to home on cloudy nights, the ability to discriminate sea water from different sources in the laboratory and the ability to return to pools with the immediate environment destroyed further indicated the importance of olfaction in the homing mechanism of O. maculosus. How the fish finds its way from the release point to its home range is still not known with certainty. However, it is suggested that the fish homed by (i) following odour streams originating from its home area or (ii) an exploratory search process or (iii) a combination of the two processes.

description: We report multi-wavelength power spectra of diffuse Galactic dust emission from BLAST observations at 250, 350, and 500 microns in Galactic Plane fields in Cygnus X and Aquila. These submillimeter power spectra statistically quantify the self-similar structure observable over a broad range of scales and can be used to assess the cirrus noise which limits the detection of faint point sources. The advent of submillimeter surveys with the Herschel Space Observatory makes the wavelength dependence a matter of interest. We show that the observed relative amplitudes of the power spectra can be related through a spectral energy distribution (SED). Fitting a simple modified black body to this SED, we find the dust temperature in Cygnus X to be 19.9 +/- 1.3 K and in the Aquila region 16.9 +/- 0.7 K. Our empirical estimates provide important new insight into the substantial cirrus noise that will be encountered in forthcoming observations.

description: Man and God in the Works of Robinson Jeffers Two of the greatest questions-any man can ask and attempt to answer in his lifetime were consistently handled by Robinson, Jeffers in his poetry: \Who is God?\" and \"What is man?\" This thesis attempts through extensive reference to Jeffers' innermost-thoughts as faithfully recorded in his short poems to plot the record of the poet's wrestling with \"these questions; old coins /Rubbed faceless dateless.\" Robinson Jeffers' considerations of the primordial human yearning for God and the conjectural provenance of man rank him in the rare company of the. great poets. Over the; years Robinson Jeffers wrote little Which revealed a basic new. concept of God but he did much to emphasize and elucidate the nature and divine attributes of God. With man the case.: s somewhat different. Jeffers' view of man did 'alter-- slightly. The early Jeffers anticipated the possibility of man embracing a rational; and natural deity. Experience indicated otherwise and the poet's view of man never warm or encomiastic became colder still and more searchingly realistic. The appalling spectacle of the Second World War only served to vindicate Jeffers' harsh view of man a view which he staunchly held to his death. On the other hand Jeffers' vision for man based as it is on the poet's love of his God did not alter over the years. Robinson Jeffers felt from the outset that man while he had not yet begun to attain his spiritual potential had an honorable future before him. Even in his own lifetime Jeffers held that man already possessed the wherewithal (but none of the resolve) to \"choose truth\" at last. This discrepancy between man's potential and his actual performance deeply grieved and dismayed the poet of Tor House. To the end however Robinson Jeffers cherished the long-term hope that man might one day \"Come of age\" that in the words of an old friend humanity might \"pass through the present crisis and emerge in a complete renascence of godliness.\" The searing impact of Jeffers' religious experience provides the core for his poetry. More than any other factor Robinson Jeffers' theology is central to the understanding of what he actually wrote. His view of the omnipotent monistic self-torturing God of fate is the primum mobile of Jeffers' achievement as poet. Because he is so intensely religious Jeffers has been intensely misunderstood in his own secular age. The God whose signature is the beauty of things is undeniably present in the natural world Jeffers felt to be divine. But an order of men devoutly in tune with the God of Robinson Jeffers' poetry is yet to be born."
title: Porta Appia e le Mura Aureliane. Fasi costruttive e risarcimenti delle strutture murarie

description:

L’idea di questo lavoro è nata dalla osservazione ravvicinata delle superfici esterne, e per tutta la loro altezza, di Porta Appia in occasione dei lavori di restauro eseguiti per il Giubileo del 2000. L’esame diretto delle murature è stato qui sviluppato sia alla luce degli studi che, con diversi approcci, hanno approfondito la storia delle Mura Aureliane, sia utilizzando un grafico vettoriale sul lato est della torre ovest della Porta (interno ed esterno), ritenuto la porzione più rappresentativa delle vicende costruttive che l’hanno interessata. Ad una panoramica sui diversi interventi che si sono susseguiti nel tempo sul complesso del circuito ad integrazione e sviluppo dell’originario impianto di Aureliano seguono alcune riflessioni su particolarità tecniche che caratterizzano le diverse tipologie costruttive identificabili lungo le mura. Tali elementi possono rivelarsi, se affiancati ad evidenze stratigrafiche ancora leggibili, un valido ausilio nel tentativo di collocare cronologicamente i differenti brani murari. Il lavoro si sofferma poi sui sistemi di addossamento delle murature delle diverse fasi costruttive che è stato possibile riscontrare in alcune torri e si conclude con una raccolta di schede sintetiche sulle tipologie murarie dei paramenti individuate nel complesso di Porta Appia e ricorrenti nel circuito di Aureliano. Nel lavoro si evidenziano: i tratti residuali della prima fabbrica di Aureliano (fondazioni e vano scale); l’attribuzione ad Onorio delle torri circolari e dei basamenti marmorei con il contributo di alcune integrazioni da parte di Valentiniano III; la plausibilità della datazione all’VIII-IX secolo del risarcimento dall’altezza del bastione laterizio della parte anteriore della torre occidentale crollata probabilmente in seguito ad un terremoto; la datazione tra la metà del XII e la metà del XIII secolo della realizzazione dei pilastri di rinforzo all’interno della torre; il consistente intervento di Niccolò V soprattutto nella zona sommitale del corpo scale delle torri.

description: Since Mandelbrot's paradigmatic revolution, fractals have become powerful tools for comprehending the scaling characteristics of natural phenomena, from the generation of coastlines to plant growth. Research has shown the robustness of fractal-mathematics for characterizing geological properties. In the realm of porous and fractured media, fractal theory has profound implications. Drawing from microscale knowledge, fractal patterns can describe transport properties in porous and fractured media, including size distributions of pores and fractures, and pore irregularities (e.g., tortuosity and constrictivity). In this contribution, we explore transformative advancements in petrophysics, applying fractal models to predict key properties like porosity, permeability, and electrical conductivity. Diverse fractal objects, such as Sierpinski carpets and Menger sponges, play pivotal roles in upscaling procedures. They allow derivations of transport properties for saturated and partially saturated media, above and below freezing temperatures, and considering hysteretic behavior and reactive media processes. The integration of fractal-based relationships into modelling approaches opens new avenues for hydrogeophysics and critical zone geophysics.

description: We present our first experimental determination of the magnetic noise of a superspinglass made of < 1 pico-liter frozen ferrofluid. The measurements were performed with a local magnetic field sensor based on Hall microprobes operated with the spinning current technique. The results obtained, though preliminary, qualitatively agree with the theoretical predictions of Fluctuation-Dissipation theorem (FDT) violation [1].

description: The long term goal of large-scale chemical tagging is to use stellar elemental abundances as a tracer of dispersed substructures of the Galactic disk. The identification of such lost stellar aggregates and the exploration of their chemical properties will be key in understanding the formation and evolution of the disk. Present day stellar structures such as open clusters and moving groups are the ideal testing grounds for the viability of chemical tagging, as they are believed to be the remnants of the original larger starforming aggregates. Until recently, high accuracy elemental abundance studies of open clusters and moving groups having been lacking in the literature. In this paper we examine recent high resolution abundance studies of open clusters to explore the various abundance trends and reasses the prospects of large-scale chemical tagging.

description: We observed (22) Kalliope and its companion Linus with the integral-field spectrograph OSIRIS, which is coupled to the adaptive optics system at the W.M. Keck II telescope on March 25 2008. We present, for the first time, component-resolved spectra acquired simultaneously in each of the Zbb (1-1.18 um), Jbb (1.18-1.42 um), Hbb (1.47-1.80 um), and Kbb (1.97-2.38 um) bands. The spectra of the two bodies are remarkably similar and imply that both bodies were formed at the same time from the same material; such as via incomplete re-accretion after a major impact on the precursor body.

description: We study and construct non-abelian hermitian Yang-Mills (HYM) instantons on Calabi-Yau cones. By means of a particular isometry preserving ansatz, the HYM equations are reduced to a novel Higgs-Yang-Mills flow on the Einstein-Kahler base. For any 2d-dimensional Calabi-Yau cone, we find explicit solutions of the flow equations that correspond to non-trivial SU(d) HYM instantons. These can be regarded as deformations of the spin connection of the Calabi-Yau cone.

The development of the theme of suffering and redemption in the novels of Patrick White
Creators: name: Bernard, Ruth
Publisher: name: University Of Tasmania
Year: 2023

description: There is a remarkable continuity and coherence of thought in the work of Patrick White. In this thesis, an attempt has been made to show the development of the underlying and recurring theme of suffering leading, ultimately, to redemption. It has been possible to trace a clear progression from the nihilism expressed in the first two books to a positive avowal of faith in the later and more mature novels. This seems to reflect a personal development in the author during the years 1939 to 1961, and, for this reason, his work has been treated chronologically. In chapters I and II, dealing with Happy Valley and The Living and the Dead, the suffering of the main characters is shown to reflect a sense of hopelessness and despair at the inevitable loneliness of man and at the futility of life itself. The Aunt's Story, discussed in chapter III, contains a more positive statement that truth is revealed to those who suffer; however, as revelation and peace seem attainable only in madness, the implicit hopefulness of The Aunt's Story remains questionable. There is a decisive change in the next book and this has been noted in chapter IV. In The Tree of Man, there is a very real attempt to see life in broader terms and to transform suffering into a beneficent experience, leading to humility and serenity. Humility is the key-word to Voss and the redemptive theme culminates in Riders in the Chariot. The author's concepts of humility, of good and evil, of revelation and redemption, are examined in chapters V and VI. Throughout, the imagery used by Patrick White, his symbolism, his mysticism, his predilection for the simple and simple-minded, even the mad, his violent reaction against the ugly manifestations of this \plastic\" age and its dehumanising effect on people his use of irony and social satire are related to his central theme. The theme itself is fundamentally religious: Patrick White proclaims his belief that by striving and suffering man is redeemable."

description: We have investigated the magnetic and dielectric properties of $A_2$CoSi$_2$O$_7$ ($A$=Ca, Sr, and Ba) crystals with a two-dimensional network of CoO$_4$ and SiO$_4$ tetrahedra connected with each other through the corners. In Ca$_2$CoSi$_2$O$_7$, a weak ferromagnetic transition occurs at 5.7 K, where the dielectric constant parallel to the c axis shows a concomitant anomaly. The large magnetocapacitance effect is observed below 5.7 K; $Δ\varepsilon (H)/\varepsilon (0) \equiv [\varepsilon (H)-\varepsilon (0)]/\varepsilon (0)$ reaches 13 % at 5.1 K\@. These results indicate a strong coupling between the magnetism and dielectricity in Ca$_2$CoSi$_2$O$_7$. Sr$_2$CoSi$_2$O$_7$ shows a similar magnetoelectric behavior to that of Ca$_2$CoSi$_2$O$_7$. In contrast, in Ba$_2$CoSi$_2$O$_7$, which has the different arrangement of SiO$_4$ and CoO$_4$ tetrahedra from that of Ca$_2$CoSi$_2$O$_7$, the magnetocapacitance is hardly observed. The key for the magnetocapacitance effect of $A_2$CoSi$_2$O$_7$ lies in the quasi-two-dimensional crystal structure.
