description: In our investigation of poly(vinylidene fluoride) (PVDF) films embedded with Au–BaTiO3 (AuBT) nanoparticles, we noted a synergistic improvement in both thermal stability and dielectric properties. PVDF films with varying concentrations of AuBT were expertly fabricated. Remarkably, the films retained their flexibility even at a high volume fraction of filler (fAuBT=0.5). The predominant phases of PVDF (α, β, and γ) were observed. An increase in fAuBT resulted in a modest decrease in the melting temperature, while simultaneously causing a significant 40% increase in thermal conductivity compared to pure PVDF. The dielectric permittivity reached ∼160 at 1 kHz, while maintaining a loss tangent of ∼0.05. These improvements were attributed to discrete Au growth on BT particles, hindering conduction in PVDF. The rise in dielectric response resulted from interfacial polarization and inherent high dielectric permittivity of BT.

The demand for public transport in Hobart
Creators: name: Kjar, J
Publisher: name: University Of Tasmania
Year: 2023

description: This dissertation is an attempt to provide a causal explanation for the changes in demand for public transport in Hobart which have occurred during the past two decades, with the use of an econometric model.In Chapter l the need for a reappraisal of existing and future plans for road construction in the city areas is examined, followed by a brief discussion of the ways in which the results obtained from this study may be found useful.The second chapter is concerned with a review of three models of the demand for public transport which have been proposed by Australian and overseas authors.Each model considered was an extension of the traditional consumer demand theory, with demand depending on price and income; however certain other behavioural hypotheses are included in each of these models and their contributions are assessed.

description: We propose a new method for computing the ground state properties and the time evolution of infinite chains based on a transverse contraction of the tensor network. The method does not require finite size extrapolation and avoids explicit truncation of the bond dimension along the evolution. By folding the network in the time direction prior to contraction, time dependent expectation values and dynamic correlation functions can be computed after much longer evolution time than with any previous method. Moreover, the algorithm we propose can be used for the study of some non-invariant infinite chains, including impurity models.

The lateral torsional buckling of open thin-walled beams
Creators: name: DeVall, Ronald Homer
Publisher: name: University of British Columbia
Year: 2011

description: This thesis is concerned with the development of a stiffness matrix for the study of a large range of stability problems for beams of arbitrary, open, thin-walled cross sections. This is done by first developing, using a consistent set of common engineering assumptions, a non-linear relation between the forces and the displacements of the beam. These relations are then substituted into the beam equilibrium equations to give a set of three differential equations of equilibrium in terms of the displacements. These differential equations are solved using an iteration technique. A member stiffness matrix is generated when the iterated solution is used with the non-linear deflection relations. The resulting fourteen by fourteen matrix includes the regular six forces plus a bi-moment at each end. The matrix is tested against known solutions and agreement is seen to be excellent in all cases. All the terms necessary for the building of the matrix are given in the Appendices.
Optimization of rectangular plane frames using box's complex method.
Creators: name: Burke, Benedict Paul
Publisher: name: University of British Columbia
Year: 2011

description: This study is concerned with the minimum cost design of a multi-storey building. The building consists of rectangular steel plane frames which are evenly spaced and support identical floors and a roof. The frame spacing, the column positions within the frame, and the number of intermediate beams spanning between frames are optimized using Box's Complex method and the optimum solution verified by an exhaustive search procedure. Member sizes for the frame and floor system are determined by a fully-stressed design criterion, for the AISC code, within the limits of a discrete set of member properties. The optimum design for several frames with various widths and heights is determined and the influence of the above variables, and the effect of cost parameters on the optimum solution is illustrated and the results discussed.

Quantum Hall plateau transition in graphene with spatially correlated random hopping

description: We investigate how the criticality of the quantum Hall plateau transition in disordered graphene differs from those in the ordinary quantum Hall systems, based on the honeycomb lattice with ripples modeled as random hoppings. The criticality of the graphene-specific n=0 Landau level is found to change dramatically to an anomalous, almost exact fixed point as soon as we make the random hopping spatially correlated over a few bond lengths. We attribute this to the preserved chiral symmetry and suppressed scattering between K and K' points in the Brillouin zone. The results suggest that a fixed point for random Dirac fermions with chiral symmetry can be realized in free-standing, clean graphene with ripples.

Validation of the SatGEM Velocity Dataset using Argo Data
Creators: name: Roach, Christopher
Publisher: name: University Of Tasmania
Year: 2023

description: The 4D SatGEM velocity model of the Southern Ocean has been derived from satellite altimetry and a Gravest Empirical Mode (GEM) model of temperature and salinity. The validity of the SatGEM model is assessed in this study by numerical forward modelling of Argo float trajectories through the 4D velocity fields. Univariate statistical analysis of simulated and actual path lengths, together with analysis of the misfit between simulated and actual surfacing positions, suggests that the SatGEM model provides an adequate representation of the gross features of the Southern Ocean. However, on a local scale there is significant variability in misfit due to a combination of statistical fluctuations, the limited SatGEM model resolution and complex local velocity fields. A high proportion of large relative misfit cycles are apparent for short Argo path lengths suggesting that the Argo float trajectories in these areas may be strongly influenced by complex small-scale flow features that cannot be adequately resolved in the SatGEM model. Argo float cycles with path lengths in excess of 50km and small relative misfits are effectively randomly distributed. However statistically significant clusters of large relative misfit cycles are apparent particularly in areas of known small-scale eddy current development such as east of the Kerguelen Plateau and also in the Brazil-Falklands Convergence where GEM models based on satellite altimetry are known to be inaccurate. The angular misfit for medium and small relative misfit Argo cycles is normally distributed suggesting that variability in this case arises due to statistical processes. The uniform distribution of angular misfit for large relative misfit cycles is suggestive of more random chaotic processes likely related to flow bifurcations in zones with complex velocity structure. In these cases the relative misfit is highly sensitive to the initial descent position of the float in the velocity model. Validation of the SatGEM model using Argo float data suggests that velocity models derived from satellite altimetry and GEM derived temperature and salinity fields can provide adequate representations of ocean dynamics for large-scale investigations but the small-scale applications of these models are limited primarily by their spatial resolution and hence their inability to accurately model complex local flow features.
title: A Phenomenological Inquiry Into the Nature of the Sacred
Creators: name: Janssen, Ana Maria
Publisher: name: Old Dominion University Libraries
Year: 1999

description: There is good reason to believe that sacred experience is available to all humans. Yet the question of the sacred is frequently reduced to a debate between believers of various religions. As the focus of contention narrows, the ubiquity of sacred experience is neglected. Keeping this in mind, this analysis of the sacred confines itself strictly to the phenomenon of the sacred as a human experience, without confirming or denying the existence of a god or the veracity of any system of belief. Heidegger's Phenomenology is a useful model for such an analysis precisely because it lays aside conjecture about the existence of realities beyond human capacity, striving instead to engage reality as it is experienced by human beings in order to gain insight into the human condition.

Being and sacred experience are equiprimordial. The sacred is a part of every Dasein's world; even those Daseins who never directly experience the sacred still receive the foundational premises of meaningfulness by way of the values put forth in myths, sacred texts and social customs. Dasein understands its self and the world as participating in the structure of sense established by sacred experience prior to any rational or conscious action it may undertake in its everyday life.

description: In this paper we show how a gravitational field generated by a given energy-momentum distribution (for all realistic cases) can be represented by distinct geometrical structures (Lorentzian, teleparallel and non null nonmetricity spacetimes) or that we even can dispense all those geometrical structures and simply represent the gravitational field as a field in the Faraday's sense living in Minkowski spacetime. The explicit Lagrangian density for this theory is given and the field equations (which are Maxwell's like equations) are shown to be equivalent to Einstein's equations. Some examples are worked in detail in order to convince the reader that the geometrical structure of a manifold (modulus some topological constraints) is conventional as already emphasized by Poincare long ago, and thus the realization that there are disctints geometrical representations (and a physical model related to a deformation of the continuum supporting Minkowski spacetime) for any realistic gravitational field strongly suggests that we must investigate the origin of its physical nature. We hope that this paper will convince readers that this is indeed the case.

description: Photo-assisted transport through a mesoscopic conductor occurs when an oscillatory (AC) voltage is superposed to the constant (DC) bias which is imposed on this conductor. Of particular interest is the photo assisted shot noise, which has been investigated theoretically and experimentally for several types of samples. For DC biased conductors, a detection scheme for finite frequency noise using a dissipative resonant circuit, which is inductively coupled to the mesoscopic device, was developped recently. We argue that the detection of the finite frequency photo-assisted shot noise can be achieved with the same setup, despite the fact that time translational invariance is absent here. We show that a measure of the photo-assisted shot noise can be obtained through the charge correlator associated with the resonant circuit, where the latter is averaged over the AC drive frequency. We test our predictions for a point contact placed in the fractional quantum Hall effect regime, for the case of weak backscattering. The Keldysh elements of the photo-assisted noise correlator are computed. For simple Laughlin fractions, the measured photo-assisted shot noise displays peaks at the frequency corresponding to the DC bias voltage, as well as satellite peaks separated by the AC drive frequency.

description: Based on the first-principles plane wave calculations, we showed that Ca adsorbed on graphene can serve as a high-capacity hydrogen storage medium, which can be recycled by operations at room temperature. Ca is chemisorbed by donating part of its 4s-charge to the empty $π^*$-band of graphene. At the end adsorbed Ca atom becomes positively charged and the semi-metallic graphene change into a metallic state. While each of adsorbed Ca atoms forming the (4x4) pattern on the graphene can absorb up to five H_2 molecules, hydrogen storage capacity can be increased to 8.4 wt % by adsorbing Ca to both sides of graphene and by increasing the coverage to form the (2x2) pattern. Clustering of Ca atoms is hindered by the repulsive Coulomb interaction between charged Ca atoms.

Non-thermal galactic background radiation

description: This thesis presents the results and analysis of data obtained using the Llanherne low-frequency array. Surveys of the Galaxy at five frequencies in the range 2 to 20 MHz have been made and the data have been assembled into maps covering the area 320¬¨‚àû ‚Äöv¢¬ß ‚Äövá‚àû ‚Äöv¢¬ß 30¬¨‚àû 30 ¬¨‚àû and -25¬¨‚àû ‚Äöv¢¬ß b ‚Äöv¢¬ß 22 ¬¨‚àû . The data from these maps are combined with data from seven earlier continuum surveys to produce galactic radio spectra in various directions. A summary is made of most of the measurements, at frequencies less than approximately 400 MHz, 'of the galactic background radiation and their interpretation. Two new composite maps, at 10 and 30 MHz, are presented. These, combined with the 85 MHz all-sky map, are used to illustrate the variation of the galactic non-thermal radiation across the sky, and with frequency. The galactic spectra are interpreted in terms of a model of the Galaxy in which synchrotron emission, and absorption in HII regions predominate in spiral arms. However, it is proposed that the synchrotron emission arms and the arms defined by HII regions are not coincident. In addition to the HII absorbing gas the model incorporates a much broader uniform absorbing HI gas which is responsible for high latitude absorption, pulsar signal dispersion and Faraday rotation. For the HI gas it is found that ‚Äöv†¬¥ne2Te¬¨vò1.35 dl ‚Äöv¢v† 1.1 x 10¬¨vò7 cm¬¨vò6 K¬¨vò1 . 35 pc For the HII gas the above quantity varies for different arms.

Legacies from nurturers in tourism; inspiring people for communities
Creators: name: Wiltshier, Peter
Publisher: name: Journal of Tourism & Development
Year: 2017

description: In this paper a review of pre-requisites for supply side competency in developing communitybased tourism is offered. Using an interpretive and phenomenological approach, the skills, aptitudes and capacity to nurture within the community, are considered in a focus on improving a destination’s ability to sustain tourism as an element of development. This development agenda is dependent on marshalling an array of skills in a complex, differentiated and individualised marketplace. It is difficult to achieve triple-bottom line sustainability without acknowledging key skills in nurturing planning, policy interpretation, building of networks and partnerships, building relationships with other hosts in the community, understanding and interpreting triple-bottom line sustainability, mentoring others, understanding lifestyle choices, innovating whilst at all times enjoying and living a chosen life (Tinsley and Lynch, 2001). Nine UK based informants prioritise the antecedents of successful tourism development from a community based approach. This paper seeks to identify and illuminate practices amongst stakeholders termed ‘nurturers’ that develop tourism and destinations through excitement of image and identity, engagement of many and often diverse groups of people, capturing values and beliefs that are often inimitable and working with supportive public sector stakeholders.

description: We present a high-resolution spectrum of a microlensed G dwarf in the Galactic bulge with spectroscopic temperature T_eff = 5600 +/- 180 K. This I~21 mag star was magnified by a factor ranging from 1160 to 1300 at the time of observation. Its high metallicity ([Fe/H] = 0.33 +/- 0.15) places this star at the upper end of the bulge giant metallicity distribution. Using a K-S test, we find a 1.6% probability that the published microlensed bulge dwarfs share an underlying distribution with bulge giants, properly accounting for a radial bulge metallicity gradient. We obtain abundance measurements for 15 elements and perform a rigorous error analysis that includes covariances between parameters. This star, like bulge giants with the same metallicity, shows no alpha enhancement. It confirms the chemical abundance trends observed in previously analyzed bulge dwarfs. At supersolar metallicities, we observe a discrepancy between bulge giant and bulge dwarf Na abundances.

title: The Theology of Father Brown
Creators: name: Flynn, Catherine Miles
Publisher: name: Old Dominion University Libraries
Year: 1991

description: This thesis explores the theological thought of G. K. Chesterton, particularly as it is found in his detective short stories about Father Brown. In his other works (e.g., Orthodoxy, Heretics, and his many books of essays), the theology of Chesterton is obvious. However, in the light, whimsical Father Brown stories the theology expressed is often profound, but underrated if not ignored by his critics. Specific examples from his stories will be used to highlight the theological points within the mysteries.

The life and times of Chesterton are discussed as having highly influenced his thought. His unconventional religious upbringing, in particular, allowed for the freedom he felt to express his thoughts on religious issues. The times in which he lived are also of importance to the religious attitudes reflected in his stories.

Other factors of note for this topic are: the genre of detective fiction and how this form was used by Chesterton to make a point within the mystery; Father John O'Connor, the model for Father Brown; and a look at Chesterton as a Thomistic thinker as reflected in his great work, The Dumb ox, and in the quaint character of Father Brown.

description: We recently performed a study of a sample of relaxed, cooling core galaxy clusters with deep Very Large Array observations at 1.4 GHz. We find that in the central regions of A1835, A2029, and Ophiuchus the dominant radio galaxy is surrounded by a diffuse low-brightness radio emission that takes the form of a mini-halo. Here we present the results of the analysis of the extended diffuse radio emission in these mini-halos. In order to investigate the morphological properties of the diffuse radio emission in clusters of galaxies we propose to fit their azimuthally averaged brightness profile with an exponential, obtaining the central brightness and the e-folding radius from which the radio emissivity can be calculated. We investigate the radio properties of the mini-halos in A1835, A2029, and Ophiuchus in comparison with the radio properties of a representative sample of mini-halos and halos already known in the literature. We find that radio halos can have quite different length-scales but their emissivity is remarkably similar from one halo to the other. In contrast, mini-halos span a wide range of radio emissivity. Some of them, like the Perseus mini-halos, are characterized by a radio emissivity which is more than 100 times greater than that of radio halos. On the other hand, the new mini-halos in cooling core clusters analyzed in this work, namely A2029, Ophiuchus, and A1835, have a radio emissivity which is much more typical of halos in merging clusters rather than similar to that of the other mini-halos previously known.

Large deflection analysis of shallow framed structures.
Creators: name: Radomske, Brian Arthur
Publisher: name: University of British Columbia
Year: 2011

description: Elastic structures exhibit instabilities which arise through the occurrence of finite displacements even when constitutive properties remain linear. A non-linear analysis which recognizes rotations in the strain displacement relationship is formulated for analyzing three-dimensional framed structures. A finite element method is used whereby the rotations within each element are restricted in size by use of a local element reference frame attached to the element. Two such coordinate systems are developed. Then an incremental solution technique based on an instantaneous linearization of a Taylor series expansion of the forces about the displacement configuration at the beginning of each increment is developed. The snap-through buckling of shallow frames, arches and domes is studied with a view to documenting the effect on the equilibrium paths of the type of moving coordinate frame, the number of elements, and the size of the increment step.
Wine tourism in an agritourism context: insight into agritourism providers’ perceptions

description: Rural regions abounding in vineyards provide a perfect setting for blending wine and agricultural tourism. Both types of tourism offer a varied combination of heterogeneous agricultural products and experiences, which add value to rural regions. In this article, wine tourism is described as part of a wider agritourism phenomenon. We start with a brief summary of an extensive literature review of the concepts of ‘wine tourism’ and ‘agritourism’. Some of the key themes resulting from this reading exercise were then confronted with the reality in the Vila Real district. Six in-depth interviews were conducted with the managers of accommodation units, which are officially categorised as agritourism units. Thus, a first set of data was collected which will allow a better understanding of the place of wine and agritourism in that area, which partially integrates the Demarcated Douro Wine Region. In other words, the supply side was analysed by comparing what happens in the Vila Real district with global widespread practices concerning the following topics: What are the main motivations of the managers, how do they perceive agritourism’s benefits, what are their attitudes towards heritage preservation and how do they profile the agritourism visitors? The research results will increase insight into the agritourism reality and allow us to formulate valuable guidelines for the future development of the sector.

Swiftian Feminity: Taylor Swift's Gender Identity and Branding
Creators: name: Gomez, Dessi
Publisher: name: University of Notre Dame
Year: 2023

description: From Introduction: 'The public constructs Taylor Swift as if she were an idea, not a person, according to her gender and her gender expression. These constructions are intertwined with her breakout into fame as “America’s sweetheart” and “ultimate good girl.” As she grew up in front of the public, she began to be attached to or associated with her most current boyfriend, and as she dated more boys and men, the construction of her as a “serial dater” developed and became almost constantly employed in gossip magazines as well as radio talk. As Swift’s career progressed, her musical storytelling became more and more detailed, which added a layer to the serial dater persona that turned her into someone who dated guys just to write songs about them. An evolution can be seen in Swift’s career when she goes from eloquently describing her relationships to responding to commentary made about her personality, her gender, and other ways in which she expresses herself. Many of her songs allow for revealing analysis of themes involving gender, specifically how she responds to portrayals of herself based on her gender and her love life. A common theme Swift employs in her songs hinges on extreme caricatures that are created around her girlhood and womanhood, mainly those of the good girl and those of the serial dater. It is important to note that Swift exhibits what scholar Jack Halberstam describes as “the idealization of white femininity,” or what is upheld as the highest racially ranked form of femininity or girlhood: that of a white woman (1). Swift demonstrates an understanding of gender as “an interlocking system of performances and forms of self-knowing.” She deftly complicates her own gender as she entertains her audience, receives commentary and scrutiny from the media and processes these perceptions in interviews (1). In this way, her self-knowing connects to her presentation of identity (further addressed in the third chapter, on politics).'

description: A new analysis of the Lunar Prospector epithermal neutron data is presented, providing an improved map of the distribution of hydrogen near to the lunar poles. This is achieved using a specially developed pixon image reconstruction algorithm to deconvolve the instrumental response of the Lunar Prospector's neutron spectrometer from the observed data, while simultaneously suppressing the statistical noise. The results show that these data alone require the hydrogen to be concentrated into the cold traps at up to 1 wt% water-equivalent hydrogen. This combination of localisation and high concentration suggests that the hydrogen is present either in the form of a volatile compound or as solar wind protons implanted into small regolith grains.

Bacterial symbionts of insect pathogenic nematodes of the families Steinernematidae and Heterorhabditidae
Creators: name: Akhurst, RJ
Publisher: name: University Of Tasmania
Year: 2023

description: Insect pathogenic nematodes of the families Steinermatidae and Heterorhabditidae from 42 populations (four, genera and over nine species) from Australasia, Europe and North America were found to be symbiotically associated with bacteria of the genus Xenorhabdus. A taxonomic study of Xenorhabdus showed that the bacterial symbionts of the Heterorhabditidae were all X. Zuminescens and those of the Steinernematidae, with one possible exception, were all X. nematophilus. Numerical analysis of the taxonomic data indicated that the genus might be heterogeneous. Although the symbionts of most of the Steinernematidae (including Steinernema kraussei which had previously been reported to be associated with a Flavobacterium sp.) were classified within one species, the differences between the bacteria associated with the various steinernematid species were great enough to warrant the erection of four subspecies. Results obtained with some tests used in the taxonomic study differed from those previously reported. Amended descriptions of the genus Xenorhabdus and its two species are proposed. Each Xenorhabdus species was found to produce two forms of colony. One form, designated the primary form, promoted significantly greater nematode fecundity than did the secondary; it produced antimicrobial substances whereas the secondary did not; and it was the form usually found in the infective stage nematodes. The primary form was unstable under many conditions, resulting in production of the secondary form which in two subspecies was also unstable reverting to the primary form.

description: In their comment \cite{Sun} on our study of phonon heat transport in Nd$_2$CuO$_4$ \cite{Li}, Sun and Ando estimate that the phonon mean free path at low temperature is roughly half the width of the single crystal used in our study, from which they argue that phonon scattering cannot be dominated by sample boundaries. Here we show that their use of specific heat data on Nd$_2$CuO$_4$, which contains a large magnetic contribution at low temperature that is difficult to reliably extract, leads to an underestimate of the mean free path by a factor two compared to an estimate based on the specific heat data of the non-magnetic isostructural analog Pr$_2$CuO$_4$. This removes the apparent contradiction raised by Sun and Ando.

Two-dimensional equivalent stiffness analysis of soil-structure interaction problems

description: The finite element technique is a powerful method to study the dynamic response of a structure taking into account the effects of ground conditions. However, limitations of computer storage capacity and cost presently prevent its general application to three-dimensional problems. In this thesis it is shown that three-dimensional problems can be analyzed by applying appropriate modification factors to two-dimensional (plane strain) analyses. Modification factors are first determined analytically by comparing the dynamic response of both strip and rectangular footings (uniform shear stress) for a range of input frequencies. It is found that for input frequencies which are less than the fundamental period of the soild layer the modification factor is essentially independent of the input frequency. This suggests that the modification factors could be obtained from static analyses. Modification factors based on static stiffness analyses for both uniform shear stress and uniform shear displacement (rigid foundation) conditions were obtained and were found to be in close agreement with those obtained from the dynamic analyses. Variation of the modification factor with both the depth of the layer and the ratio of the sides of the rectangular base are given in graphical form. These factors may be applied to finite element place strain analysis to predict the dynamic response of three-dimensional structures.
Bohmian Mechanics and Quantum Information

description: Many recent results suggest that quantum theory is about information, and that quantum theory is best understood as arising from principles concerning information and information processing. At the same time, by far the simplest version of quantum mechanics, Bohmian mechanics, is concerned, not with information but with the behavior of an objective microscopic reality given by particles and their positions. What I would like to do here is to examine whether, and to what extent, the importance of information, observation, and the like in quantum theory can be understood from a Bohmian perspective. I would like to explore the hypothesis that the idea that information plays a special role in physics naturally emerges in a Bohmian universe.

description: First-principles plane wave calculations predict that Li can be adsorbed on graphene forming a uniform and stable coverage on both sides. A significant part of the electronic charge of the Li-$2s$ orbital is donated to graphene and is accommodated by its distorted $π^*$-bands. As a result, semimetallic graphene and semiconducting graphene ribbons change into good metals. It is even more remarkable that Li covered graphene can serve as a high-capacity hydrogen storage medium with each adsorbed Li absorbing up to four H$_2$ molecules amounting to a gravimetric density of 12.8 wt%.

description: This paper recalls the proximal point method. We study two iterative algorithms: the Blahut-Arimoto algorithm for computing the capacity of arbitrary discrete memoryless channels, as an example of an iterative algorithm working with probability density estimates and the iterative decoding of the Bit Interleaved Coded Modulation (BICM-ID). For these iterative algorithms, we apply the proximal point method which allows new interpretations with improved convergence rate.
Woodfuel energy supply to rural India : problems & perspectives

Publisher: name: University Of Tasmania

description: India, in the present time, is passing through an acute shortage of fuelwood in the rural sector where three quarters of her population live. To solve this \Second Energy Crisis\" of India there have evolved several technical solutions of which the rural energy plantation or the Social Forestry Plantation Programme is the most important one. Various physical financial and technical constraints related to these programmes can be solved by technical or scientific means. But the real issues of the problem lie deeper enmeshed in the Indian social system which is highly complex in nature. There are enormous temptations to tackle the solution of the problem through technical means but this is only a partial remedy. What is more important is the forming of policy and its implementation through administrative mechanisms. This is because any attempts to apply only technical innovation in the existing unequal society of India have always resulted in failure. In spite of increased production of food grains through the \"green revolution\" the poorer sections are still starving - because they have no access to these food grains. Similarly through technical means there will be enormous generation of fuelwood resources - but that does not guarantee that the poor will have it. What is needed is a radical approach to evolve good policy through which the \"poorest of the poor\" will have access to this resource. Until that is done rural India's energy problem will remain as it is."

description: A convincing detection of primordial non-Gaussianity in the local form of the bispectrum, whose amplitude is given by the fNL parameter, offers a powerful test of inflation. In this paper we calculate the modification of two-point cross-correlation statistics of weak lensing - galaxy-galaxy lensing and galaxy-Cosmic Microwave Background (CMB) cross-correlation - due to fNL. We derive and calculate the covariance matrix of galaxy-galaxy lensing including cosmic variance terms. We focus on large scales (l<100) for which the shape noise of the shear measurement becomes irrelevant and cosmic variance dominates the error budget. For a modest degree of non-Gaussianity, fNL=+/-50, modifications of the galaxy-galaxy lensing signal at the 10% level are seen on scales R~300 Mpc, and grow rapidly toward larger scales as \propto R^2. We also see a clear signature of the baryonic acoustic oscillation feature in the matter power spectrum at ~150 Mpc, which can be measured by next-generation lensing experiments. In addition we can probe the local-form primordial non-Gaussianity in the galaxy-CMB lensing signal by correlating the lensing potential reconstructed from CMB with high-z galaxies. For example, for fNL=+/-50, we find that the galaxy-CMB lensing cross power spectrum is modified by ~10% at l~40, and by a factor of two at l~10, for a population of galaxies at z=2 with a bias of 2. The effect is greater for more highly biased populations at larger z; thus, high-z galaxy surveys cross-correlated with CMB offer a yet another probe of primordial non-Gaussianity.

Hearing the silence : responding to the call of children
Creators: name: Anderson, HI
Publisher: name: University Of Tasmania

description: It may seem odd to talk about hearing silence, given the noise and clamour of our everyday world - even more paradoxical to think about hearing silence in the world of the classroom. It seems that silence is a state that we often wish for, a kind of still emptiness where we might find momentary peace and succour amidst the hubbub of our modern, stressful lives. How do we understand silence - what meanings does it hold for us? Do we understand it merely as an absence of noise - a state of non-hearing? What does silence mean to a person who is deaf? Sometimes we talk of silence as ominous or threatening and other times we speak of a pregnant silence - a waiting or an expectation of something imminent. Musically, we appreciate silence in relation to sound. We respond to the juxtaposition of sound and silence often vicariously, being carried along by insistent rhythms and beats, or being lulled into a soporific stupor by less urgent and more ill-defined configurations of sound and silence. The setting in which silence occurs then is vital - what comes before it, what surrounds it and what follows, is the context by which we might appreciate its meaning.
The Pt isotopes: comparing the Interacting Boson Model with Configuration Mixing and the Extended Consistent-Q formalism

description: The role of intruder configurations in the description of energy spectra and B(E2) values in the Pt region is analyzed. In particular, we study the differences between Interacting Boson Model calculations with or without the inclusion of intruder states in the even Pt nuclei $^{172-194}$Pt. As a result, it shows that for the description of a subset of the existing experimental data, i.e., energy spectra and absolute B(E2) values up to an excitation energy of about 1.5 MeV, both approaches seem to be equally valid. We explain these similarities between both model spaces through an appropriate mapping. We point out the need for a more extensive comparison, encompassing a data set as broad (and complete) as possible to confront with both theoretical approaches in order to test the detailed structure of the nuclear wave functions.
